Hi all, first of all … why would you want to do that ?

There are lots of manufacturers and sites that will happily assemble and set up a PC for you. So why would you want to build your own ?

Picture. Meme. We're looking at the back of a computer lying flat on a table. To the left and looking out is a white and dark furred cat. The caption is "Oh i, I upgraded your RAM"

The answer for me is very simple. I get total choice on what’s going into the machine for both the components and the software. I can put a bit of extra money in one thing that I think is important and make a sacrifice in something else that I don’t think will matter. I can future proof without breaking the bank. And probably the most important, it gets set up without any of the garbage software that the original equipment manufacturers (OEMs) will preinstall that either doesn’t go away completely when you uninstall it or it comes back again. It’s also bundled stuff like the malware that masquerades as branded anti-virus security software.

You could even choose to go away from the Microsoft Windows ecosystem and go to Linux now. That’s more viable, although I’ll come back to that in a while.

The most important thing is to do as much research as possible before you buy. Retails and online sites will be very keen to put discounts on selected models in their range. If you get tempted by those, ask yourself why the discount is happening. Is the discount because they have a stack of stock they can’t shift out of the warehouse because no one buys it ? Or are they dumping stock because it’s just gone obsolete and end of line. I’ve actually taken advantage of that for my last two laptops, they were both acquired on heavy end of line discounts and happened to be specifications that met my requirement.

This is probably the time for … Disclosure note ! All the decisions for the bits here were mine, I paid for everything, the companies mentioned have no idea who I am and no approaches had been made prior to selection of the bits. (Outside of the usual Overclockers and Scan we’ve got your email in our database robot marketing emails)

Picture. Meme. We're looking at a black and white cat sitting before an opened laptop computer. Their right paw is on the computer mouse. The captions are "I ordered a vault and a speaker online." "They arrived safe and sound"

The catalyst for this post is to introduce the new build PC that appeared here over Easter. It’s the BunnyBox, named for when it was built again :-D. It follows Pumpkin, assembled on Oct 31 2011 and Meltdown, built on the hottest July day of 2019. But the main aim is to tell all of you reading that : You can do this too. Yes. You can. If you can handle a screwdriver and have a fairly light touch, you can build your home brew PC as well.

The key thing is to do all of the research before you part with any money. I have to admit to making a few mistakes with the BunnyBox, some of which were down to not researching properly, some were trusting the reviews a bit too much. Some mistakes and problems were making some bad assumptions. Oh and I may have forgotten to add the system memory to the order and had to hang around Stoke on Trent a while so they could fetch some out of the warehouse.

But the absolute key thing is : It’s YOUR money. YOUR decision to commit to spending it. Don’t ever feel pressured about spending YOUR money unless you’re absolutely comfortable in doing so. That goes for any pressure you may feel to up the spec when you don’t feel that’s affordable or presents value that you’re comfortable with.

Here’s the BunnyBox spec from Partpicker (linky). Partpicker is actually a really decent site to go to when researching the bits that go together to make a PC. They cut their selections down to what’s compatible. So if you choose an AMD cpu, they won’t show motherboards made for Intel chips. When I updated the list for the memory, it didn’t show memory that the board couldn’t handle. So it’s a handy thing to start from to see what’s out there and quickly get a list of bits.

Picture. We're looking down at a white computer motherboard with various sockets. Middle left is a black square of a processor socket. Above left are 4 black long sockets. Centre screen is a storage slot. And there's a long white socket for a graphics card.

That’s your motherboard, which everything plugs in to. There are different connectors for everything and they only go in one way around, so the only mistake you can make is to press too hard and break something that way. Don’t worry about that. Modern computer electronics are far more robust than when I was a lad too. It used to be that TTL (Transistor Transistor Logic) chips would break if you touched them wrong, electro static discharge wrist bands used to be required so you wouldn’t zap the bits. I don’t believe you need those these days. (Please no sue me if something doesn’t work ! 😀 ).

The first thing to go in was a 4TB Solid State Device (SSD) storage device. This is an nVME drive, which is the faster one. It’s an M2 format, which is a small card like a stick of chewing gum. Don’t eat it, too crunchy and expensive 😀

Picture. We're looking down at the white motherboard again, which has had a storage device added in the centre. It's a long thing flat card with a black finned metal heatsink on top, with the labels Crucial T500 to tell people what it is.

Here comes my first error, because I bought the more expensive one with a heatsink on. Cos … Meltdown’s similar SSD gave no problems in almost 6 years but it did run warm. The mistake was not researching that the board came with its own heatsink. I didn’t need to buy the one fixed to the drive. Oh well, coulda saved some cash.

I bought a single SSD because I was assuming that BunnyBox would be running a version of the Linux Operating System and didn’t know how that handled multiple drives. So I bought a bigger (4TB) cheaper one for significantly less than a quicker one of the same size.

Techie note – you’ll see PCIe, that’s the interface of how the components talk to each other. If you look at a computer architecture diagram, the wiring will connect blocks together mostly with the Peripheral Component Interconnect express (PCIe). It’s express cos it’s the considerably improved Mk2 version of PCI, which first got into PCs in the 90s. M2 SSD drives will show a Gen 4, Gen 5 and if you read this in a few years, probably Gen 6 and beyond. The newer versions offer improved transfer rates which might give you a benefit if you’re doing heavy data crunching but I figured I could save pennies (to go into better other bits) by not noticing going for a cheaper ultra fast drive.

Picture. Computer build. We're looking down at the white motherboard. Centre screen we see the square spot for the processor but the aim here is to show the memory. It's a rectangula stick component covered by a black metal heatsink. There are gold connectors on the base and a notch is cut slightly off centre.

That’s the memory going in. That picture actually shows the stick the wrong way around, because I wanted to draw attention to the notch that’s in the bottom of the stick. That’s a polarising notch and makes sure the memory goes in the correct way around because the polarising notch is slightly off the centre. When it’s in right, the grabby arms to the sides of the socket will do their grabby arm thing and close up. You might need to rest the board on something very solid here so it doesn’t flex when you put the memory in. Use the anti-static bag it comes in between Board and Solid Thing to protect everything.

Something else to note here is the sockets to use. There are 4 on the board there, so I could add more in later. However if you look real close (left side of the socket) and can read upside down, you’ll see DDR_A1, DDR_A2, DDR_B1 and DDR_B2 with a “First” beside them. Processors can gobble up 128 bits of data at a time, however the memory sticks send out only 64 bits at a time. So you double them up to get full performance. But they only work doubled up if they’re in the correct sockets. The board manual will tell you which sockets are best. If you put the memory in sockets DDR_A1 and DDR_B2 (mismatched sockets) then your new PC may not boot up at all.

Picture. We're looking at a huge red framed PC chassis. The internals are black. There are three large fans in the base, two very large fans back and right and a very large fan on the left. Two red dwagon helpers are dwarfed at the base.

Pardon the messiness of my bedsheet ! The camera picks up all of the dust and I don’t think I have the hand capacity to edit it out :-D. That’s the box, it’s an absolute unit of a Montech King 95 Pro. The 6 fans there are utterly silent when the machine is on and have the gloriness of already being assembled and cabled in to the box. You might see a bit of ducting below and there is more ducting above. The power supply goes in the back and the motherboard sits on that vertical plate. I’m extremely impressed with this case, it has exceptional build quality, it was easy to fit the All In One Cooler in the box above there and the box can fit the biggest coolers. However, it’s also a massive unit, comes in at 13kg and was a pricey £125. Honestly, with the build quality and 6 included silent fans, probably well worth that.

Picture. We're looking at the matt black chassis bones of the PC. To the right, a box with a fan in it and the label Lian Li. There is a double row of connectors on the left of the box. Wires stretch up the bones of the box with a couple of plugs on the left. Our small red dwagon helper is supervising.

That’s the power supply going in there. Two things here … don’t skimp on the quality, so extra money went into the Lian Li supply there. I have a few power supply makers on my list of shame, Lian Li is actually a new one for me but they have a stellar reputation. The other is to get a big enough one that it can take it easy with the components in the box. So a 750W supply taking it easy at a 500W draw will last so much longer than a 500W supply straining to consistently deliver the same 500W.

It’s a false economy to go cheap on the power supply. Getting a good name one (like Lian Li) will lead to a more reliable and stable machine. And if it breaks, standards like 80+ GOLD means that it won’t break anything else when it … explodes. Not like a friend’s PC which broke all of its components when the cheap no name inadequate power supply melted. PSUs don’t explode … but don’t take one apart to find out as there is 115/240V in there, definitely don’t mess with the big round capacitors, those are the bits that can go boom.

That’s a modular power supply. The older ones came with all of their cables attached to ends on the inside, so they had a mass of unused cable to hide. A modular supply has those sockets there, so you only plug in the cables you require. Less untidy.

Picture. We're looking down at the PC. The white motherboard is now installed in the case. There is a silver processor where the black socket cover was before. The large red dwagon helper is supervising from the left.

That’s skipping ahead a little to the motherboard installed in the box with the processor in there too. The box there is an ATX format box, with ATX dating back to the 90s. Literally IBM AT PC extended. There are newer formats like ITX out there but ATX has been consistent for decades. There is a sockets backplane on the bottom right and the board is secured by an array of small screws.

That’s an AMD Ryzen 7 9800x3d and BunnyBox has one of those due to a big discount that put it in an unbeatable price / performance bracket. I also have a lot of wariness about Intel at the moment because their quality and part resilience has gone downhill lately due to decisions made by their management.

The installation is a bit different again this time around. That’s an AMD AM5 socket. The lever on the left is for a so-called Zero Insertion Force socket. (It’s not zero force!) You use the lever to allow the socket to open and slide the ickle processor into the socket. Again, it’s polarized with the little dot you’ll see on the lower right corner to make sure you put it in the right way round. When you lower the retaining bracket, the black cover seen previously pops off and the lever then locks it in to place.

We can see a couple of black plastic things there too, every processor needs to be cooled because they’ll kick out a lot more heat when they’re busy. The first cooler this machine had was an All In One (AIO) Cooler by Thermalright. These work by having a heat block that clamps on top of the processor using the hooks on the plastic things above and below. The AIO is then connected to a radiator with a couple of pipes filled with cooling fluid. There’s a pump that circulates the fluid and fans to cool the radiator. It’s a lot easier to install coolers on the AM5 generation of socket than the previous AM4 generation.

Picture. We're looking at the fully assembled PC there. Top of shot, three fans connected to a radiator fixed to the top of the case. Two white pipes from the right lead to a cylindrical block on top of the processor. We see the fans from before, plus there is a graphics card installed with "Force RTX", actually GeForce RTX.

That’s everything together ! Not quite, because there are buttons and plugs and lights and sockets to wire up too. The PC case has 2 older USB, 1 new USB-C, a couple of audio sockets, a reset button, a power button and a power light. These all plug into sockets on the board, the motherboard manual will have the where to’s here.

But that is actually it. The graphics card is in there as well. Note how close it is to the processor, I’ll come back to that. Also note how close the memory is on the right there. (Foreshadowing anyone ? 😀 )

The next thing is to take a long solid drink, clean up the mess from any blood sacrifices that might have happened along the way. Depending on the build quality of the components, you might have picked up a cut or two. Cheap cases have many more sharp edges. I only got a very minor cut this time around for the somewhat required blood sacrifice. It keeps the Machine Spirit happy :-D.

Plan A for BunnyBox was to abandon Microsoft and go over to Linux. I attempted using Bazzite Linux, as the reviews and things written about it were favourable. It’s worth checking out Linux, it’s free so you lose nothing but a bit of time in exchange for learning about the alternatives that are out there.

This lasted 1 day.

He he, overly dramatic moment there. The machine actually fired up and installed easily first time but I removed it from the machine because I was getting terrible performance with older games like Idle Champions and Motorsport Manager. The Steam platform is starting to get more games designed for Linux but can also support Windows only games by using the Proton translation library. That wasn’t working so good for me, possibly because the Bazzite install didn’t have the info to allow it to properly use the brand new to market nVidia 5060Ti 16GB I bought. And because I couldn’t see how to install the new drivers, I put Bazzite in the bin and went straight back to the known entity of Windows with a WIndows 11 install.

You live, you learn, you add more knowledge.

Picture. Meme. We're looking at a concerned looking Corgi dog lying on a bed with an open book in front of them. The captions are "This homework looks hard" "Do you want me to eat it?"

So I pop Windows in there, install the Horizon Zero Dawn in there and run its benchmark. All is good. Temperatures go up but it gives a result of 160 fps wibblies which was up from the 71 fps wibblies that Meltdown could achieve. It’s an older game but has a good benchmark for testing purposes.

I then look at the BOINC science sums application and … the temperatures rapidly go off into orbit and as AMD Ryzens do, the machine goes into thermal protection where it slows itself down to around a tenth of its potential performance. This is where the panic comes in. I’ll do a bit TLDR there (this post has gone LONG!) and say that I think the AIO cooler wasn’t taking any heat away from the processor, the pipes and radiator were cold. So I swapped it out for …

Picture. A rather filmy misty obscured look into the finalised BunnyBox PC build. We see the fans rimmed in blue light with a huge cooler in the centre. It's made out two big metal blocks sandwiching an equally large fan.

Yeah. I went back to what I know and bought the most massive air cooler from a good make that I could get hold of at short notice. That’s a Noctua NH-D15 and while it is a fantastic cooler, I did make a couple of errors when choosing it. The fan there is a massive 140mm, there are supposed to be two but the other one clashes on the memory sticks. The cooler is installed off axis as well, about 7mm above where it should be, because it clashes with the graphics card below.

So while Partpicker will give you a LOT of info about whether everything will fit together, it doesn’t know everything. I don’t know everything. I still make errors like that by (going back to the start) not doing all of the research. I checked whether the cooler would fit in the case … not whether it would fit around the rest of the components.

But it all works, BunnyBox is rock solid so far, it’s an absolute powerhouse running the performance hungry Star Wars Outlaws with no frame drops on very high detail so I’m a happy little bunnydwagon here tapping this post into it.

I think that’s where I’d better leave it before I end up posting tomorrow instead of today. I’ll leave you with :

You got this, you can do it too. Read about what you’re planning to put together, use hardware review sites (like Tomshardware) and borrow the specs from their testing rigs. Learn about the bits and it’ll help you out when you have the screwdriver in hand and assembling.

Take it easy, take your time. Don’t panic if things don’t turn on immediately. Just check that all the wires are where they are supposed to be. Repeat your steps if you have to, measure twice install once that kind of thing.

Animated picture. We're looking at a claymation animated sheep. They are looking towards the right and holding up both paws making a thumbs up motion. The caption is "I believe in you".

And compare notes with your local geeky techy community too. We’ll love to gossip about components and tempt people into buying new bits and pieces. Just remember that it’s your money, your budget, stick to those limits. If you’re not sure about what you’re about to do, hold off and learn a bit more. Computer bits only get cheaper and better if you wait.

May your Machine Spirits be contented little beasties.

Advent day, the droids go fourth

Hello everyone, what’s behind the door today ?

Picture. Our advent scene is building, the red dwagon is on the left, Leia is at the back and the TIE Fighter is chasing the X Wing. In front, a dark grey or black robot stands, looking our way. It has a heavy thick body with thinner limbs.

Super battle droid today, which leads me to talking techie stuff 🙂

I think I’ve mentioned this before … I’m going to be upgrading the tech at some point in the not that distant future. First up … to follow today’s advent model being a droid :

New phone ! My current phone (a Pixel 4) has been properly excellent. It does all I need it to do, it’s really surprised me with how good the night sight camera mode is and the only way it gets intrusive is by nagging me to enable to back up modes that’ll have all my pictures going off to Google to be harvested by whatever AI they say isn’t going to be trained on our pictures (but you know it will be).

There are 3 things pointing me towards an upgrade :

Memory size – I do like taking pictures (and copying them through from camera) and the memory is filling up;

Battery life – it’s 5 years old now and I think the battery is degrading

Contract – it’s 5 years old now 😀 and my contract was completed a while ago.

Picture. Meme. We're looking at a person fully enclosed in white plastic armour, with black parts at the shoulder, hand and eye areas. They're holding up a bag and a phone. The captions are "Buys iPhone" "Because couldn't find the droid he was looking for."

No, it’ll be an Android phone because I don’t want to have my phone subject to Apple’s policy on forced hardware obsolescence and whether or not we own our devices. Talking of that …

My iPad Mini 2 (that’s probably 10 years old, it’s done well) looks like it’s only good for being a Kindle app thing now. It’s asking for an update to iOS 12.7, it can’t handle the latest iOS and therefore I can’t update its browser or most of the other apps to the current versions. So it’s now useless as a portable computing device, outside of being an excellent e-reader device.

If I do upgrade the iPad, it’ll be the same again because the Mini size is a good size. The display is easily readable even with my deteriorating eyes (I am old, hear my roar. It’s pain from the latest back twinge) and it’s more compact than the full size ones. Compact is good.

Might have to change that in the car though. (Gosh, this post is actually flowing from device to device, never saw that coming)

Picture. Meme. We're looking at a white car, peeking out of a black full motorcycle helmet. The captions are "Ai haz a motocycle unner here." "Mah helmet iz jus' too big"

The issue with the car is that it’s a bit low. It’s challenged by the larger speed ramps around here, so I really don’t want to take it to less paved places if I ever do the stargazing thing properly. (Gonna need to arrange some away from home storage for that I think)

I’m actually looking a bit at the Lexus LBX again, it actually has a somewhat usable boot. Other than that though, I do greatly like the 2 pedal driving of an auto box and the Toyota/Lexus hybrids mesh very well with how I like to drive. The gearbox brain aligns with how I want the car to respond when I change the throttle input. But I might need to look at something bigger. No real solid idea of what to get next though and that era of The Last Car is looming (when they ban sales of cars with petrol engines and everyone without the ability to charge an electric car is stuffed).

Car as tech ? Definitely a thing these days. It’s a long time since I drove a car possibly without any transistors in (the Fiesta didn’t even have a radio). Now it’s Bluetooth, drive by wire, brake by wire, electric throttle, two motor generators, all the engine management, a number of display screens, memory seat and all the rest of the tech in the car. There’s probably more computing power in there than my PCs even going to the turn of the century.

And there’s the next swing in something something techie to upgrade !

Picture. Meme. We're looking at a grey cat, sitting on top of an open white laptop. They're on a wooden table with a mug to the side. The caption is "My day just isn't complete if I can't spend some quality time on my computer."

The other impending forced obsolescence thing that’s looming is the end of support for Windows 10. We’ll need to hop up to Windows 11 by that point because all the bugs that Microsoft didn’t sort out in Windows 10 before end of support will become active liabilities in our PCs that will most definitely be exploited by individuals and organisations who are able to get their stuff into our machines.

I’ve had malware affect me adversely three times :

First Acer laptop, which acquired keyloggers from something associated with the Eve Online website. That saw my log in credentials getting stolen and temporary loss of account. The Eve admin people retrieved that but it did lead to the compromise of a lot of my passwords from that time.

Something nasty got in from a website, which got past the User Permission thingy popup, murdered Defender like it wasn’t there and it was corrupting my browsing, serving ads etc. That needed a system restore to fix.

Third goes way back … when a piece of malware called Blaster was fully capable of scanning the internet to find a vulnerable machine, uploading itself and infecting that machine within fifteen minutes of it being connected to the internet. Yep. This happened on a machine I was setting up with a completely fresh Windows XP install, it was able to get in and infect before anti-virus could be installed to stop it. I saw the install due to the Zonealarm (remember that ?) firewall popping up with an outgoing connection request.

My current PC, Meltdown, has done well with a Ryzen 5 3600 processor and an upgrade to a 3060Ti and bigger SSD since install. But it was struggling a little bit with the more open areas of Star Wars Outlaws and that plus that looming Windows 10 out of support is making me think I need to retire a Windows install that dates back to Oct 2011 and Windows 7 in Pumpkin and replace it with … This is what I’m looking at :

AMD Ryzen 5 again, it’s a good combination of economic to buy and the power on the chip. I’ll get 64 GB of memory this time and couple it to one of the 5060Ti graphics cards. Which means waiting until they become affordable sometime after they come out in Jan. I’ll debate until purchase whether I go for one Solid State Device (SSD) drive or two :

One SSD – it keeps things simple. But … an SSD kinda wears out over time and not in the same way as physical wear to bearings will eventually kill the old magnetic platter based drives. Each time data is written to an SSD, that takes a little bit of life out of it. Too much of that and it starts to sacrifice its total storage capacity. The 5 year old one in Meltdown that has Windows on it is still doing well and has all of its bits available but the CrystaldiskInfo application is telling me that it’s down to 57% health, which I think is based on how much it’s been writing, erasing and rewriting bits of itself.

Two SSD – one smaller one for Windows, one whopper for games. The idea is that the little one gets rewritten a lot by whatever Windows does, while the whopper for games just looks out for data storage (textures and graphics and voices are big) and doesn’t get rewritten as much.

Apparently my boot disk has had 46,572 GB happen to it and it’s just a 464.7GB drive. So each memory bit it contains has been rewritten on average of 100 times over 5 years of operation. Maybe. I might not be interpreting that right.

I think that’s it for me for tonight. Mass Effect Legendary completed downloading and I’m tempted to dive into it when I should be giving a dodgy shoulder a break.

It’s been good to be back into popping these natter chats in for you all 🙂

Where I let the geek out with cameras

Hang on, I haven’t done anything rash with money … yet …

Picture. Meme. We're looking at a cat, with paw held up to their mouth in a thoughtful looking pose. The caption is "What if that red dot is both particle and a wave?"

We might hit that as we go into what I’m about to launch into … Hopefully not that deep but let’s see how far it goes.

One thing wasn’t making sense to me yesterday with the camera specifications. If a lower f number for the aperture is better, what’s the advantage of getting a mirrorless camera with a lens that goes down to f4.0 over a mobile phone camera that was taking pictures at f1.7 aperture and the little Ixus that was going to f3.6 aperture. Lower number better right ?

And then I realised that I wasn’t talking like for like. The phone camera is the smallest, the Ixus camera is in the middle and the mirrorless camera is a bit of a whopper. Time to look at numbers :

Pixel 4 has 2 main cameras. Camera 1 is 12.2 megapixels with aperture f1.7 and the metadata told me it was a focal length of 4mm with a 35mm number of 27mm (I think they compare everything to a 35mm camera standard). Camera 2 is 16 MP over a 50mm telephoto sensor with aperture f2.4 and a 2x optical zoom. The Northern Light pic would have been with the Camera 1. Oh and the resolution is 96 dots per inch with each pixel being 1 micrometer (0.000001m) so the sensor will be 4mm across.

(note to geeky tendency readers – run a check over numbers as you do them to see if they make sense. A 27mm sensor in a phone doesn’t feel right, a 4mm sensor feels right)

The Ixus 265 has a 15.2MP sensor with 180 dots per inch resolution. The focal length is quoted as 4.5mm to 54mm (the lens comes in and out on a motor) for 35mm numbers of 25-300mm. The f numbers for the aperture go from f3.6 to f7.0. It does actually have 2.5 stop image stabilisation … (Spec sheet link) The sensor is 1/2.3 inches which is apparently 6.16mm across making it 50% bigger than the phone sensor. (Dunno about the sums there, feels about right again).

Let’s see what the chonky camera has …

Canon EOS R100 has a 24MP effective pixel sensor that’s 22.3mm by 14.9mm. So that’s 5.5 times the size of the phone camera. Peek back at yesterday and the focal length is 18-45mm for a 35mm equivalent of 29-72mm. The f numbers on the lens go from f4.5 to f6.3.

Picture. Meme. A very confused looking little grey cat with a white chest is looking at us. The captions are "What did the confused cat say?" and "I'm purr-plexed"

What do all those numbers really mean though ? Let’s look at the sensor first. The bigger the sensor, the more light can hit it in a set amount of time. So the mirrorless would bring in over 5 times the light information in a given amount of time, compared to the Pixel 4 camera. The little Ixus sensor brings in 1.5 times the information of the Pixel 4 sensor but …

The Pixel 4 won with the Northern Lights pictures because the Pixel could be set for a far longer exposure time. Yesterday’s picture was over a 16 second exposure, the best I could get from the Ixus was a surprisingly short 1 second. Let’s invent a unit called the Light Wibbly, the Ixus pulled in 6 LWsecs (Light Wibbly Seconds), the Pixel 4 pulled in 16LWsecs with the 4 second exposure pictures. Result, you can see Northern Lights in one camera and can’t in the other. The EOS R100 can do shutter speeds as fast as 1/4000 seconds up to an exposure of 30 seconds. So, bigger sensor, more light getting in per second, much bigger range of how long it’ll take the light in for. The R100s would pull in 22LWsecs with a 1 second exposure, which is how people can get those time lapse videos of the Northern Lights.

And that all adds up to me looking at future Google searches for “star seeing viewpoints Bristol” :-D. The Pixel was just starting to pick up galaxy background pictures … I really, really want to see those. But I’d need to be somewhere relatively remote with minimal light pollution and those areas are tough to find in the UK.

On to the focal length – a big number means that distant objects can be brought much closer. That’s how I get the really zoomed in pictures of the cricketers at Lords, the camera is operating at a really high zoom level. I’m curious as to how the 25-300mm numbers of the Ixus 265 compare to what could be gotten out of the starter 29-72mm lens of the R100 pack. But … that’s one other reason you get the cameras with interchangeable lenses. There’s a lens that goes to 800mm for being able to read the road signs in London from Bristol but that’s also £1100 so maybe not. There’s also a more affordable high aperture one for low light photography which I might have to check out (£200).

Oh gosh. Big yawn. It’s Friday afternoon / early evening and I’m going to be catching up on sleep all weekend. Time for a sum up ? First another link for some optics theories, it’ll help peeking here (linky).

Mobile phone camera – they’re doing an AMAZING job with these. They only have a tiny amount of real estate to work with in terms of space for the sensor and the depth to turn the picture from light into 1’s and 0’s. As you’ll see from the Visual Education link above, cameras benefit from having a lot of depth to focus up the image. Mobiles do a fantastic job with the space they have available and the software is incredible at making the great pictures happen. Cost is minimal because they come with the smart phone you likely have already.

Compact digital camera – they do the best they can with the package available and the little Ixus is a really flexible device. It has massive zoom capability and it fits inside a small pocket. Portability is a wonderful thing but … you have to be really careful about keeping the camera steady and it’s almost useless in minimal light conditions. The latest Ixus 285 is £270 but it looks like they’re being phased out for Powershot cameras.

Mirrorless / DSLR modular camera – they have the size and versatility to get professional level amazing photography but … they’re also way more expensive. I’m still going to get one though because I do enjoy taking pictures of Stuff and sharing them with people. The pack I’m looking at is currently £650 or you could win the lottery and get the R3 camera body for £5500 and multipurpose RF28-70mm f2L lens for £3400.

No I’m not going to be spending nearly £10k on a camera system :-D. That’s actually double what you could get a Rolls-Royce for. (True statement ! Autotrader has a 1976 Silver Shadow for £4,675) I’d actually save a few pennies more for the pretty Mk3 Spitfire going for £16k.

Oh there I go dreaming again. I wouldn’t actually want to drive a Triumph Spitfire (horrifically dangerous suspension set up) but they are a very pretty old car.

Picture meme. A red squirrel is standing on their back legs, reaching their front paws to the sky. The captions are "Stop Typing" "Stop Typing" (there was a repeat)

Ok ! have a great weekend everyone.

Hello everyone,

Gosh where did those two weeks go. I know where the first one went when I was on leave, I kinda disappeared into a Little Big Workshop addiction (again) followed by opening up Trans Road USA again and disappearing into that. And then this week at work pretty much disappeared in a flash.

Picture meme. A small grey cat is looking at the back of a television. There are three wires plugged in, with yellow, red and white plugs. The caption is "Wait I'll fix it"

So after writing last time about having a flare up and that I was upgrading the desktop with a new SSD, there was a bit more drama there last week …

So the flare up continues, my arms are less scary now than they were last week which is good. They’re still scaring people and I’ve been putting them under tubigrip to protect them but there has been at least some improvement this week. Slow and steady repairs are what I’ve been used to. It’s the quick setbacks that are why I still have the problems.

I think I have more of an answer though. I had a suspicion about garlic bread last week, still got that but I think I have another one about tomato. Yep. That’s a new mystery one connected to me enjoying tomato cup-a-soups more lately. Ah well, looks like I can’t have nice things so much. I’ve had one minor reversal since stopping the tomato cup-a-soups and I think that was from a chicken arabiatta which had tomato in it. We’ll see. The pattern has been a few good slow repair days followed by a quick set back, possibly coinciding with tomato stuff.

Talking about nice things …

Picture meme. A kitten is looking at a monitor. There is a progress bar on the screen. The captions are "my eevilll plan ... iz 7% compleet!!"

The new Solid State Device disc drive arrived. It’s a 2TB nVME unit from Crucial and it fits into one of those m2 slots. (nVME stands for nonvolatile memory express) M2 is a credit card type thing, it’s an edge connector about an inch across and the drives are about 4 inches long. Yep. I use inches.

So I look in the motherboard manual (before buying) and it’s a good modern board with a current chipset, so it should support the drive properly. It even says it in there : 2x m2 slots and “Supports nVME SSD as boot discs”. That means I could put my current m2 SSD into one slot, the new one into another and then transfer Windows from one drive to the other. The software to do that comes with the drive, they give you a limited use copy of Acronis True Image, which is excellent software to do the job hassle free. The idea is that the copy is done and then you swap the drives over in the machine. Job done, easy.

(Disclosure note is appropriate at this point – I bought the drive myself, nothing was provided apart from that free limited use copy of the drive copy software, I recommend it because it works)

Does it work out like that ?

No.

Problem one – with the 2x m2 slots in use, the machine doesn’t go into the BIOS. That’s where you do the basic setting up of the machine, tell it what drive to load off and then it hands over to Windows. If you can’t get into the BIOS, then you’re pretty much stuffed.

I even tried swapping the graphics card over (electronic connections are somewhat shared between the graphics and the second m2 slot), this resulted in the board doing nothing but beeping in distress. Which was … not good.

Answer – I have a USB enclosure which the new drive is currently in. This happily proved that the problem wasn’t with the new drive … always gotta be wary of stuff being dead on arrival.

The USB enclosure is a bit slow though, so it took 3 hours for the Windows drive to get copied over and then you swap the drives over and boom, you’ve got the system running on the new drive.

No.

Where the manual says “nVME SSD as boot discs”, it means in a special RAID (Redundant Array of Independent Discs) set up which has to be carefully set up. It wouldn’t let me select the new drive as something to boot off. Without changing a setting to do that RAID thing, it wouldn’t allow me to go into the BIOS. So there’s no way to boot off that new disc (at the moment) and setting it up as a RAID array stopped Windows from being able to work with the drive.

The temporary answer, which has happily worked is :

Old SATA m2 SSD is back in there as the boot drive that the machine primarily works from. New nVME M2 SSD is in the USB enclosure plugged in at the back of the machine, whirring away as a data drive. And that works too, albeit with some issues. The drive access is nice and fast, Starfield plays very nicely but instead of giving 4000MB/s data rates, it’s limited to 40MB/s. I’m not seeing this as a significant issue but I am going to address it.

The permanent solution will be to acquire another expansion card to put in the machine and then the new drive goes into that, hopefully being pretty quick again too.

So drama on my outsides, drama with that new bit for the computer.

I did a quick test in Starfield and then promptly didn’t open the game again. Gaming habits be like that :-D.

Oh and look ! A power blip (that’s rare here) and it repeated another thing I said this week about systems reacting to power interruptions : Computer rides through it, lights flicker, telly was fine but the modem reset so I’m now waiting for it to connect again.

Time for a quiet finish to the evening watching Tashnarr play a bit of Apex Legends plus a bit of book. Current one is Descendant Machine by Gareth L Powell, he writes great books. They’re always intriguing, gritty and with interesting and varied characters. It’s in his Continuance series, where humanity has been evicted from the Earth and now wander the galaxy in a fleet of Arks. Part of the set up is that substrate (hyperspace equivalent) is dependant on a human navigator and machine AI ship combination. It feels inspired by The Culture from Iain M Banks but it’s its own unique universe. Well worth checking out, as are the rest of the books that Gareth L Powell has given us.

To the book !

PS I’m on Bluesky as well now, with the revelation that Twixxer might be going behind a paywall being a catalyst for some including me. Just look for Sleepydwagonman, that’ll be me.

PS2 I now need to reset the clocks on cooker, microwave, alarm clock … Oh well.

Hello everyone,

Been a busy week including an away trip where I was watching the mpg gauge in the car just go up and up, super tired now. (But mostly watching the road because that’s what we do). How did Red do ? The peak mpg was reading 61 at one point, which probably works out to an actual 59. Not bad for a petrol car.

But this isn’t going to be about that bit of tech, although I’m very happy and quietly pleased at how they’ve taken what I think are the same mechanicals from my first CT and improved them. Good times. Thumbnail ?

Picture. We're looking at one of the green dwagons, It's on a cookie that's about 3 times its size.
Protect the cookie !

Thumbnail. And it’s been too long since I’ve had a cookie that size. I do miss the Happy Cookie Place from the Xmas markets … they didn’t go even for a few years before all the lockdowns started happening.

Anyway, what’s this one about ? I like to occasionally look at the PC market, just to see what the moves are in it. What the trends are. What’s available, what’s listed for sale but isn’t actually available. Whether it’s worth me looking at investing in an upgrade or an update. The quick spoiler is that the almost 4 year old Meltdown (my desktop) is still going strong and I don’t need to replace anything significant on there any time soon.

The laptop, which found the name Dwagonsong, has been a very happy upgrade over the last almost year. It’s an Acer Swift which is much lighter than the Asus gaming laptop I had before. That’s ok, the two laptops had different purposes. Saying that though, the Asus was poor in its display and I didn’t appreciate that they tried to block the upgradeability by using threadlock on the screw that would hold in an expansion drive. That’s really poor Mr Asus. So what’s out there ?

Picture. A cat is sitting in front of a very large fan. The caption is "Using technology to efficiently and evenly distribute cat hairs around your home.
I do like the big air coolers

So … PCs … I’m going to do two build ideas this time. The first is one which would be a mostly like for like for Meltdown, the second would be a worthwhile upgrade. They’ll both be AMD Ryzen based machines with an nVidia graphics card. The Ryzen machines are excellent for performance and I have my doubts for the Intels now, especially with the work laptop which is suffering hardware defects (although these aren’t significant enough to get it replaced). And I haven’t got that trust back in the AMD graphics yet after having a card go boom 1 month after warranty and headaches with their cards in the Radeon 1800 era. (I think they were 1800s)

Ahem. Starting out with what everything plugs in to … you have the motherboard. These look like they’ve ratcheted up in price now. You select these by checking what the processor needs and then the motherboard determines what memory is required. DDR4 memory won’t fit into a DDR5 board. Things like that.

Better machine motherboard : Asus Prime X670-P wifi with Socket AM5 – £275

Like for like : MSI MAG X570S Tomahawk MAX Wifi (they do like the long names) with Socket AM4 – £240 and these boards look like they’ve gone rare.

Processor : AMD Ryzen 5 7600X Socket AM5 for £250 or AMD Ryzen 5 5600 Socket AM4 for £150.

Memory : 64GB in a pair of Kingston Fury Beast 32GB DDR5 5600 sticks for Better one costing £210 or 32GB of Kingston Fury Beast (again with the silly name) DDR4 3200 for £87. The DDR5 is what the X670-P board needs, the X570S board needs DDR4. The X670 and X570 say what the chipset is. The motherboard is the foundation of the machine so it pays to get a good one. Meltdown has been rock solid in a Asrock X570 board, which I think cost around £180, so that £240 is a chunky increase in price.

One thing is that the stocks level seems to have mostly recovered to pre-pandemic and global electronics shortage levels and the prices are getting there. But they’re still up on the whole and some items like power supplies are still hard to get hold of.

Moving on to graphics and the equivalent to mine is the 4060Ti card (Meltdown has a last generation 3060Ti card), these will cost £400.

Powering everything is a power supply unit box, which will slot in and then you plug it in to everything. I’ve used Corsair power supplies for a long time and they’ve done me well … but the cheapest good enough one that’s available today is a 850W version for £148. That’s a bit much in both money and size. But if you find yourself needing to replace in a hurry, you work with what you can get hold of.

Disclosure note time ! I’m using prices off Overclockers UK this time just because they’re the first ones I thought of looking at. I’ve only ever had one freebie from an electronics company and that was a mouse won in a raffle. Everything else has been bought by me.

Every PC needs a bit of storage to put the Operating System on and all of the games. I’m still looking at using a Solid State Device drive to put Windows on and a selection of games, paired with a conventional hard disc to put everything else on. I like having a huge supply of memes but those don’t need to be on an SSD. So :

SSD : I’ve been very happy with Crucial again and they supply M2 NVME drives in 1TB for £48 and 4TB for £200. That’s way more than we need. An M2 drive is one that plugs into the motherboard, for extra speed and NVME means it has the electronics to fully unlock that speed.

Hard disc : Arbitrarily going for Western Digital and we have 2 7200rpm drives (they spin faster they send data out faster) for £190 for a 6TB drive and £240 for a 10TB drive. Thinking about it there, you’d be better sacrificing a bit of space and just putting the 4TB SSD in there.

I mentioned cooling earlier and this is actually one thing where I differ significantly between what I’d advise at work and at home. Water cooling is a really efficient way of taking heat away from one place and dumping it out at another. But home isn’t a place that actually benefits from that. You really don’t want fluids around your electronics if it’s not necessary. So I go for massive air coolers instead :

Picture. We're looking at a box with a computer cooler on the front. It's bigger than my red plushie dwagon which is to the right of shot. Both are resting on a dark blue towel.

My usual thing with computer coolers is to go for the really big ones with a couple of huge fans. Meltdown has the Coolermaster MA610P in the picture above. It runs cool (50 degrees C on idle going up to 70 when pushed) and is super quiet. The idea is that the big fans push a lot of cooling air through and don’t need to spin fast to do that. Spinning fast leads to noise and noise is bad. So the other week when we had a power cut, I was confused why nothing happened when I turned my monitor on. Turned out that I wasn’t noticing that the PC was off. It’s that quiet. Anyway, Cooler Master MA612 Stealth cooler for £70. It’s worth investing more there so you get less noise out. Oh and add in £20 for a bit of metal to stick on that M2 drive, those get toasty.

Finally, you need something to put everything in. I’ve learned a few things with Meltdown’s box :

Not getting Bitfenix again, the quality was low and I almost needed the mendstick (big hammer) because a manufacturing defect had distorted the case almost enough to stop me getting the power supply to go in.

Drive bays are useless now, it’s easy to use a USB DVD or Bluray drive.

USB ports that are on the top of a machine are a total dust trap, including if they’re at a 45 degree angle.

I’d recommend having a look at a case before buying it, although I’ve never actually done this. The one that got the eye on OCUK was the Silverstone Fara R1 mid tower case for £65 but only because it had ports on the front instead of on top. I don’t think it’s worth spending that much on the case but you want a sizeable one that you then hide away somewhere. Big is easy and means the air can get through it easily.

Last bits – not including keyboard, mouse or screen, those are very personal preference. But you will want to do your research before going for anything there. Oh and you want Windows, which is currently £110.

How much is all that ?

The upgrade one is around £2000. The cheaper one is around £1500 with both hard discs. The only upgrade for the cheaper one which would really help Meltdown is the big SSD (currently got a slow 512GB one), so that’s £200 for the 4TB one, everything else is a small improvement. It would be around £1500 to upgrade Meltdown to the Ryzen 5 7600X machine. It’s worth noting though that PC Specialist could build something close to the £1500 machine for £1400. But … they’re putting in components like Corsair memory (like their psus, wouldn’t touch their memory) which I heavily avoid.

So … that’s not going to happen 😀 although I can’t be held responsible for the consequences if that big SSD appears with a big discount.

Picture. Meme. We're looking at a note for 50 something folded in half. At the fold is an electric wire. The captions are "Have been charging it since yesterday. Still not 100".

That’s all for today. One lesson is : if you don’t get benefit from spending the money, keep it. The laptop change was very worthwhile, especially because I’m travelling more. The desktop will hang in there for a few more years yet.

Means more money for Lego (and a bunch of house things that need doing).

Nite all !

Hello everyone,

I must stop apologising for it being a while between posts and actually post some more :-D. Last time, it was near the start of a week off and I’d been fighting new laptop issues all day. And I have to admit, getting a little stressed about it. Especially about the iTunes thing. If you’re here about iTunes not talking to iPhones, skip ahead a bit (keyword “victory”). Or hopefully enjoy my rambling too :-D.

Buyer’s remorse and all that. I get that a fair bit.

There’s been a birthday as well …

Cute animal meme. We're looking at a ginger kitten standing on their back legs and looking sad. The captions are "I want to wish you a very happy birthday" and "Just so you know ... I love cake..."
Cake !

Yep. Added another bit of age again. An away trip happened last week and I’m definitely still feeling that now, even after a chilled out weekend. It was only 1 hour of time difference but that meant getting moving at an equivalent 5.30am for a few days, plus travel followed by highly disrupted sleep times.

I can’t talk much about work trips though, things like the location you went to can give far too much away about what you’re working on and who you work for. And we have to protect that kind of stuff from the weird people on the internet.

Yep, I know, I’m a weird person on the internet but I don’t inflict anything bad on anyone on the internet, I just have fun drawing chuckles out of people. Must do more of the art again, to add to the memes. The memes still happen, if a doable idea pops into the head the memes quickly follow. It’s like having a toolkit that you can apply as you need it. Turning a photo into a meme can happen very rapidly especially if the photography cooperates. Drawing a new sketch, that takes a while even with the rapid style I was going for.

Buyer’s remorse ?

Meme picture. We're looking at the top half of a tiger's face with the paws on top of a fence. The captions are "After Black Friday and Cyber Monday comes Buyer's Remorse Tuesday and Hiding from my Creditors Wednesday."
Black Friday is nearly upon us …

Hmm. Looks like they’ve updated the WordPress editor and it’s a small change where instead of there being a + button to press when you’re adding a picture, you need to press /. I’m not a fan of changes like that, they seem like changes for change’s sake. Unlike twitter where the changes seem to be to set a record on how quickly you can burn down a multi billion dollar business.

Laptop ? I think I mentioned that it’s an Acer Swift 3 this time around. I went down a little on spec with a smaller hard disc than ideal in order to take advantage of a bigger discount. It’s also a little smaller at 14 inches. The important spec bits are 1.2kg, 14″ screen (IPS), 16GB memory and 512GB SSD. And all that is working very nicely. The catalyst for buying was to drop from the 2.7kg Asus gaming laptop (which I never gamed on) to something more suitable for travelling around. Oh and the screen in the Asus laptop was dull and terrible, this one is far superior. The keyboard is nice too. That’s the things that made me go for the Acer in the end, it felt nice in the shop (although I bought from the Acer online shop)

It’s Windows 11 too, which honestly isn’t too bad. It’s another unnecessary change from Microsoft in order to relieve more money out of people for updates but it feels like the switch is necessary in order to introduce cyber security architecture in the Operating System which is vitally important in today’s increasingly dangerous online environment.

Apart from that – the Settings area is more confusing than before. It appears to be another extension on what happened to Windows 10, with its awkward mix of old Windows 7 era controls and the newer style. I haven’t found the settings yet to enable different power modes for on battery and on mains power. I just did a check and apparently it does have these. You can tell in the Task Manager, which gives an accurate frequency meter. It’s 2GHz on power and light loading, down to 1.3GHz on light loading. Less speed = less power draw = more battery life.

Time for a disclosure note – I bought the laptop, although I did get £150 off on £800 value via the discounts you can get on the Acer store.

The SSD makes it much smoother than the Asus. Either that or Windows 11 performs better than Windows 10. Not sure there, it could be a change from 8GB up to 16GB, that extra memory gives breathing room for Windows. Taskbar behaviour is different. Windows 10 gives you more options. Handy tip – Windows key + X is a shortcut to many very useful features like Task Manager, Device Manager, Run, Search etc.

I used Device Manager to fix an iTunes issue … I insist on using iTunes 10.7 because it was the last one with the iTunes DJ feature. (Auto generated playlist which adds tracks if it runs out). This means I also have to keep my iPodPhone (iPhone 5) on old software … Anything above iOS 6 won’t talk to the iTunes. Apparently it can’t take anything past iOS 8.3 anyway so that exphone won’t be getting any data again from anywhere that isn’t the iTunes library. Long story short (and popping a search engine optimisation in !)

My iTunes 10.7 was not detecting my iPhone because the iTunes 12 driver was causing a conflict. If you’ve come here via a search engine and have the same issue, here you go : The Portable Devices entry for Apple iPhone didn’t fix it. I needed to go down to Universal Serial Bus controllers where (if it’s not working), you’ll see an entry for “Apple Mobile Device USB composite driver”. This is the one that doesn’t work. Reinstalling the “Apple Mobile Device USB driver” (yep, is subtle) has gotten the iPodPhone talking to the iTunes again. VICTORY

I haven’t sorted out the Homeshare system yet though, I’ll keep that one for another day. I’ve managed to listen to 1642 unique tracks so far, which puts the chance of a repeat being randomly chosen down to around 1 in 10.

I think the exhaustion is starting to really hit now though, so it’s time to wrap up.

Still here, hanging in there after realising that the burn out probably hit around Mar/Apr 2020 when the world changed a lot. Been looking to try and recover from that, although it might need more of a reset to do so.

It has been good being out and about more though. It seems like the pain that follows the out and about is lessening as I do it more, although it has definitely caught up to me today.

Anyway – time to close with : looking forwards to the run in to Xmas. Lots to do. Things to see. The markets are open, so I’ll look to visit those at least a few times. Hopefully the cookies are back ! It’s been good seeing people more regularly again. Work situation is way better than before I changed last year, I have the confidence again to own what I’m doing and be able to make stuff happen with it.

Be safe and well everyone, see you again sometime soon.

Hello everyone,

It’s been a while again. I think that might be partly down to burn out that I realised might have been going on for perhaps 2 and a half years now. It’s an insidious thing, burn out, you know something’s going on because your patterns change but it tends to creep in and make those changes to your behaviours without you realising.

So for me, it probably started at the beginning of the covid period and there were a few work things that really brought it out. Yep, even more than the extreme skin condition that I had for too many years before that. Perhaps that just wore down the reserves so that the anxiety of the first lockdown periods (and probable covid around March to June 2020) coupled with the work stuff activated the burn out. One symptom may actually have been the creation of this blog, as a knock on to getting annoyed with how Google/Blogger were changing how you use that system. I think that’s been a positive change overall though as it’s let me learn a few things that I took for granted with Blogger. Oh wait ! Caption.

Meme picture. A contented looking sleeping cat is resting underneath blankets. The captions are "I can't get out of bed..." "These blankets have accepted me as one of their own and if I leave now I might lose their trust."
Trust in the blankets

I’m off work this week, it felt like I’d been running backwards and went straight into a wall. Some of that is increasing anxiety about things I should be getting sorted out but don’t have the energy to attempt to start. Which is its own feedback loop as well. Because the job isn’t started, the anxiety increases. I need to look into other ways of getting that sorted out.

What has been going on ? Been doing space again …

Game screenshot. Elite Dangerous. We're looking at a small trapezoid shaped spacecraft on a landing pad. It is green on the outside with a yellow circle in the centre. The circle has a demonic grin and eyes in black.
Tea 89 is after your Tea

That’s my old Cobra Mk3 again from Elite Dangerous, with one of the free paint packs from the latest drops campaign. Good seasonal paint job although I think when Tea 89 comes out again, I’ll put it back to the orange and white livery. There wasn’t a special paint job for Tiamat’s Chariot :

Game screenshot. Elite Dangerous. We're looking at a star filled area of space. To the lower left, we see our spaceship with purple flame coming from a series of engines. The ship is mostly hidden in silhouette with a small sun in the centre. There is a planet in dark eclipse to the right, we can see the city lights.
A trading we will go

There’s actually a bit of unfinished business there with a Community Goal in progress. With today’s activities, I haven’t had a chance to drop off the cargo I collected on the weekend. Oh and I had a look at another space game too :

Game screenshot. Eve Online. We're looking at a starfield with cloudy backdrops. There are user interface features to the right, a ship status display at bottom centre and our little ship is in the middle of the screen.
Humble beginnings

It was good to have another look at Eve Online. It’s a persistent online universe space game, where you fly with I think it’s 10,000 other pilots. The large battles can have 1000’s of players on multiple sides with everything from little tackle frigates to titan super capital ships. Around that, there are epic battles for territory and industrialists supplying the ships to fuel those battles. Everything in the game is player built or supplied. Oh and the game is (in)famous for its espionage as well.

I got curious so I installed the game again but it’s one game I’m going to have to stay well clear on lest I do get drawn into it. Too many games, not enough time and Eve has heavy expectations on player time.

I’ve also completed the achievements on Little Big Workshop. Indeed, this might be another sign of the burn out. While I’ve dived into games like LBW, I’ve been very wary about going back into games like Elite which take a bit more energy and effort to play.

But … there is a new toy here that has taken a fair bit of mental effort today …

Meme picture. A cat is sitting on a laptop computer. They're both on a table with chairs tucked in. The caption is "To unlock your computer turn on the electric can opener"
But ! There is still food in the bowl

I splurged on a laptop … The motivating factor was with me traveling more for work, the old laptop is a bit too chonky. It’s a 2.6kg lump, the new one is a 1.2kg light 14″ screen laptop. There were other motivations as well, the screen on the old laptop is pretty poor.

What didn’t I get – HP and Dell because their performance and reliability in the work laptops is nasty. The work Dell I have now struggles to interface with the screens. It’ll sometimes refuse to connect to a screen when it’s plugged back in and suffers from worrying graphical corruption if that interface is stretched a little. I avoided getting another Asus due to the screen quality of the last one, plus I think they charge for the name as well as the equipment. Lenovo … weren’t offering the spec I wanted plus I didn’t get good vibes.

So I went with Acer again, the family has had a string of these machines and they’ve all done really well for us up to the point where they ran out of capability due to the software moving on. (Disclosure note – I bought and paid for laptop 100% although they do run fairly substantial discounts on the Acer website).

Today’s activity has been figuring out the differences with Windows 11 and starting to get everything copied over. I got worried early on because the laptop was showing signs of being unresponsive due to hardware issues but those went away as soon as I switched wifi. (Oh and after ripping Norton out). So I have the old laptop, new laptop and desktop talking to each other over the network now. It connects to the various bluetooth devices ok too.

iTunes is being more of an issue, because I’m having to authorise the computer and copy the library via Homeshare in iTunes 12 before I downgrade that back to the usable iTunes 10.7. I’ll have to look at that issue again because the Apple ecosystem isn’t sustainable there. I use iTunes 10.7 for the DJ feature, which is the only way I listen to music on it. The issue with switching laptop is that 10.7 isn’t allowed to sign in to Apple store stuff now which means alternate means required for copying the library over. Only 7000 more tracks to go (it’ll be running overnight).

Another issue I’ll be looking to sort is the sound again. Windows and laptops (especially Realtek hardware) seem to really suffer for loudness, although that might be down to me having them fight for dominance among music, stream and desktop. But Chrome does always feel quieter than the audio test and the levels from Chrome never seem particularly high. I’ll be looking into this more. One really happy thing is that Chrome has pulled my settings and tabs across from old laptop to new laptop, although the various cookies needed to be set up again.

What I do need to do is get myself out of the house. Maybe Thursday ? I think tomorrow will involve attempting to get better sleep tonight (it’s been at a premium lately) and then doing the Elite Community Goal stuff tomorrow afternoon. But I do need to get out and about because being in the house too much isn’t particularly healthy.

So … am suffering with the burn out, not really seeing an end to that at the moment but I’ll keep monitoring and attempting to look after myself better than I have been doing. The last couple of months feel like they’ve been rough too, with me going from a tummy issue on the away trip, into ginger poisoning, into probable covid again and then physical issues with a cramp tear in my leg and the shoulder coming out again.

And in the meantime, people seem to think I’m doing all right with the work now which helps a lot. The last post descended into feeling utterly devalued due to a management chain that went pretty weird. I’ve been doing better since getting out of that atmosphere.

And I’m looking forward to listening to all that music again with a fresh ear. That’s one thing proven, laptop can talk to hifi ! Hurrah. And the physical issues were starting to relent at the end of last week. Just need a proper sleep pattern again now.

Sleep well everyone, be well. And there are only 6500 tracks to copy over now.

Addendum – I was having problems getting into the laptop BIOS to reverse the rather offensive reversed Function key behaviour (where F2 does airplane mode instead of F2). You’re supposed to press F2 or something while the laptop is starting to be able to get in. This wasn’t working. However ! These people at Tenforums (link) have a very comprehensive and helpful answer. Sorted !

There are shenanigans afoot in the computing world …

Also shiny things in the sky :

What’s the shenaniganning ?

Turns out that some of the manufacturers of motherboards have figured out a way to trick the system in order to allow more wigglyamps to be shoved into processors in order to make them go faster. Beware both the reporting and the conclusions from it … The theory is that if the software in the motherboard reports one number and that number is too low, the software that governs automatic overclocking goes : I can drive this processor harder !

For this exploit, it’s the numbers that do voltage and current. The processor should only be given up to a certain limit there, any higher will make it go too hot … causing its life to be shortened. I quite liked getting 8 years out of my last processor !

Here’s numbers from my machine from just now. The science sums are turned off, so the numbers are for low activity :

(You may need to click for bigger …)

The crudely drawn arrow points to the suspect line … Apparently my machine is reporting that the processor is taking about half the power that it is actually taking. (the electrical input power will turn into heat and the heat has to be taken away – too much heat = crash and boom).

I think the sum is coming from the “Core + SoC Power” and “Core PPT” (Package Power Tracking). However, when I read the HWInfo page saying what the Power Reporting Deviation meant, there wasn’t enough there to say where it was coming from. Which makes me question its value and relevance.

The other terms there are “Core” – this is the bit that carries out the instructions. There are 6 of these on my processor. “SoC” is System on Chip, it’s the bit that connects the cores to the rest of the system. Gotta get the data in to them and the data out of them. This allows the instructions to tell the rest of the system what to do (changing the picture in the graphics card) and allows it to tell the memory and drives to feed it more data.

What do I think this actually means ? Not actually very much unless you trust your system to automatically overclock itself, as processors will do these days. I don’t believe in doing that, the automatic overclocking measures are usually intended for when the system isn’t doing very much (i.e. marketing numbers) and are meaningless when you’re running tasks on all cores, like I do with the BOINC Science Sums.

The more important numbers are the ones for temperature … and whether the system crashes or not. The computer will crash when either the temperature goes too high and the electronics can’t work thermally or when the signals are coming at it too fast and the switching isn’t fast enough. Processors are filled with transistors, which are tiny little switches. You can make them switch faster if you brute force more electrons through them.

Oh – I may have almost broken something yesterday evening as well … I was seeing if I could get more information out of the AMD Ryzen Master program and pressed one too many buttons …

My processor usually runs at around 50 degrees C on idle. It’ll go up to between 70 and 80 degrees C when it’s doing science sums (depends on ambient conditions too). I should probably actually fit the aftermarket cooler I have at some point but I’m happy with what the stock Wraith Stealth cooler does.

After clicking a button last night, while it was doing sums, the chip overclocked itself to 1.4V, 4.2GHz … and the temperatures shot up to 95 degrees C. Oops. And it didn’t crash ! I think I may have a pretty good cpu there if it survived that without crashing or other ill effects. It’s back down to the normal speeds of 1.1V, 3.6GHz.

The thing that matters with the overclocking is the temperature and whether the machine crashes or not. I’m taking a very dim view of my motherboard maker (who I won’t be recommending any more) using this software fiddle but I don’t think it actually means very much, unless you trust the automatic overclocking features … which you should never, ever use. It’s not worth it for small, inconsistent gains that shorten the life of the machine.

To the Shiny Things !

Tried putting the kettle on these geysers. The temperature was good but the lack of atmosphere makes the water boil off before the tea brews. There’s probably a way around that.

And a higher shot. I made a little error here because in chasing the geological geyser formation, the nebula ended up a bit too high. (If you drive the camera drone thing below the surface, it blacks out the screen)

I did a bit more neutron star boosting along the way, this is the Tea and Medals about to dive in to that jet cone in order to get a boost.

More nebulae :-).

A planetary nebula poking out from behind a gas giant.

 

I did like this one, it’s where I stopped on Thursday evening. Good shadows, an eclipse on the gas giant and it looks like they’ve added in some fogging too over there in the distance.

The nest stop was the Perimeter Nebula.

Today”s travels included the Perimeter Nebula.

Before heading off to the Damselfly nebula. Pretty and blue. The picture at the start of the post was taken at the neutron star inside that nebula.

The last place to visit today was the Child of Time nebula inside the Cloomeia sector. This one is another planetary nebula with …

Black hole ! This one is a tiddler black hole at just 3 solar masses. The game lets you get right up close, with this one being taken at 25km away. I’ll have a natter about spaghettification some time …

There are benign black holes and rather more malicious black holes. It depends on high big the black hole is, with the smaller ones giving worse spaghettification effects than the big ones. What is spaghettification ? It’s a difference in the force between the end of an objects that close to the black hole and the force at the end. When we stand up, there is a tiny difference in the gravity exerts on our toes and our head but it’s so small that it doesn’t matter. But if you’re close enough to a black hole, there starts being a massive difference between the gravity exerted between close and far … and the object rips apart due to differences in its weight. (Weight = Mass x Gravity with weight being a force)

I’ll probably go into that more at a later date when my brain is up to doing the numbers on it. Brain is still not quite where it should be !

Oh and I’m still loving the effects of what happens when you fly away from the black holes. The minimum speed with the hyperdrive on is 30km/s, which lets the lensing effect unfold in a rather pretty way.

Stopping point for the night – nice bit of sun there.

Last one, looking back at the companion star and the black hole will be up in the sky there. Not sure where 🙂

That’s it for me for tonight !

Stay safe, be well.
