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,

It’s been a Week again … Mostly about stuff at work where we’re trying to do lots in a very short time, without enough in the way of resources. So, situation normal there then. It means we focus in on what we can do and defer plans for what we can’t. But getting there can be pretty exhausting, so I’ve been hitting the napping hard after the work laptop gets closed up.

Picture. We're looking at the white armour of a Star Wars Stormtrooper. They're holding up a phone in their right hand and a bag in their left. The captions are "Buys iPhone" "Because couldn't find the droid he was looking for."

Enough about work though. I’ve got some purchases / upgrades coming up. Let’s get the rant out of the way first 😀

So it came round to car insurance renewal time and it looks like the insurance company (Axa – don’t go to them) has decided to get in on the 2020s trend with hiking prices. For my 2018 Lexus CT (aka Posh Prius), they upped the premium from £350 to just over £600. Wowser. The reasoning when I gave them one of those unhappy emails “How did we do” “I will never do business with you again” was :

A rise in the claims for this type of car – I have over 20 years of no claims, how other people drive is up to them.

A rise in the cost of parts for cars – it’s a 2018 car that only just went out of manufacture.

An increase in the amount of technology in cars – it’s a 2018 car that has the same amount of technology in it as it did last year. (Although I have considered getting a dashcam)

An increase in injury compensation and medical costs – I have over 20 years of no claims and have no intention of getting involved in other people’s injury claims.

Incidentally, Axa had good financial results last year with steady growth (I checked them out), decent profits and I think dividends for the shareholders too. It’s not a savage raise in charges because they’re short of money, it’s pure greed.

So … another of those customer disservice emails that acts clever but the only thing it achieves is to lodge a last impression memory in an ex customer who will remember that the next time it comes to do any business that might involve them. In short, it’s one of those emails that should never have escaped the company, like when Novotel nickel and dimed me on a hotel last year. (Incidentally, Novotel denied me access to the car that weekend, the locked secure garage was also locked to me due to me not being provided with the code until check out)

I’m with eSure this year thanks to the meerkats for £360 again. Disclosure note – I went to them, I’ve never had approaches from insurance companies apart from where I’ve had to check a “yes you can contact me” as part of the normal business with them.

Picture. A cute puppy dog is sitting to the right, with jaws firmly clamped around a laptop computer to the left. The caption is "When your laptop is running low on space But your pupper helps by giving it a megabite"

Next up is phone – I should be doing the mobile phone update soon. The one I have is a Pixel 4, which has done well over the last 4 years. It’s paid off now though, so I can go for the upgrade with not much cost. Highlights are the camera, which brought those Northern Lights pictures, battery life has been good and it’s blissfully free of the spyware and annoyanceware garbage that was on my Galaxy S7. So I’ll go for a Pixel 8 “soon”. I could hold on to the Pixel 4 but it’s been showing odd behaviour on failed incoming calls and there’s awkwardness on using its hotspot for my second work laptop.

Picture. A lady is lying down on grass dotted with yellow flowers. She's holding a camera with a long lens, pointing to the right. She's looking down and to her right where there's a fluffy grey wolf. There is a baby deer standing on her back. The caption is "A photographer is approached by a baby deer and baby wolf while out in the field."

I’m looking more seriously at cameras … I don’t think I’ll have it before Boat Life 2024 in just over a week but I’ll definitely have it for the Lords cricket in May. What am I looking at getting ?

The Canon Ixus has done well, although it has its flaws in poor image stabilisation. The upgrade would be a Canon EOS R100 mirrorless camera. These are a new type, where the mirror that sends part of the image light up to a viewfinder isn’t included in the camera. Means more light goes to the sensor but you lose the optical viewfinder. Which is fine because I haven’t used a camera viewfinder in decades, I just take the pictures using the rear display.

Here come the links ! This one is for Canon’s page with the camera, memory card, lens and bag. (Linky) Disclosure note again – I’ll go Canon because the little Ixus 265 has done very well (except needing to keep it really steady) with excellent battery life and reliability. I’ve not had any approaches from any camera makers. (Us content people have to put these disclosure notes in so we’re not hiding an inducement or ad)

The specifications on the cameras look very much of a muchness. That’s the cheaper Canon mirrorless camera, which means cheaper plastic materials used to put it together. The sensor looks like it’s the same. The trick seems to be in the lens and one thing impressing me about Canon is that they put that little bit of extra effort in to make it easier to spend your money with them. Things like a guide to what all the letters and numbers in the lens mean. (Linky again for the full how to read those numbers guide). I need to get my knowledge up to speed on why all these matter but here goes for the numpty view :

Canon RF-S lens – this is the attachment type, means it’s designed for the mirrorless cameras.

18-45mm – this is the focal length. Two numbers mean you can zoom in and out. Lower number means everything is smaller. Bigger number happens for when you zoom in. (The linky above has pictures included in the guide, well worth a peek)

F4.5-6.3 – this is the aperture size. A smaller number means a bigger aperture, which lets more light in.

IS – this is for Image Stabilisation, so the camera should still get fairly sharp pictures if you’re moving it around. This one has a 4 step image stabiliser.

STM – this stands for Stepping Motor Technology. Most motors will be designed to keep spinning. Stepper motors are designed to go direct to a position and hold there until they need to move again.

Pulling something out of the Northern Lights set :

Picture. We're looking at a dark scene. We can see some vague people shapes in the lower segment. The scene is dominated by a sky full of the eerie green and some red glow from the Northern Lights.

That’s one of the ones from the Pixel 4. It’s taken from the ship flight deck, looking out aft. You’ll be able to see some light lines to the lower left and in the stars, where the exposure time has combined with a bit of ship movement. For partially sighted readers who depend on the alt-text being read out, the light lines are perhaps about 1cm as I see them on the editing screen, going horizontally and they’re curiously only visible on a small number of the visible stars.

Good to see stars in there too. The ISO level isn’t actually too high in this one. ISO being the exposure sensitivity. The file metadata is telling me the Pixel 4 chose settings of focal length 4mm (so it’s looking at the sky as intended), F1.7 for the aperture, a whopping 16 seconds of exposure time and ISO 695. The phone was on the tripod at the time. Looks like the little Ixus was able to get down to F3.6 aperture and I got a maximum of 1s exposure time out of it.

Being able to get into the detailed settings helps a lot and the little Ixus couldn’t really give those options.

I’d add a remote trigger, for the camera being on a tripod, and a spare battery to that camera, lens, memory card and backpack package.

One thing I’d say though – if you’re doing a big purchase, like a phone, or a camera, or something bigger like a car or a house, be an Intelligent Customer. Research what you’re buying before you commit any money. Sometimes the people with the products make it easy to find out what you’re buying. Sometimes they’ll hide why their product is cheaper than the alternatives.

But the thing to take away is that it’s Your Money you’re spending. It’s only the sales person’s when they’ve done a good enough job of parting you with the money.

And enjoy what you buy ! See you next time folks 🙂

New Things Lead To Happy Thoughts

Comments Off on New Things Lead To Happy Thoughts

technology

Hello everyone,

What’s this ? Two posts in a couple of days ? I’m ok, honest. Well, mostly but I’ll get back to that later.

Picture. Meme. We're looking at a cute grey and white kitten, sitting upright. Their back leg is in a long plaster cast. The caption is "My plan to dominate the world has been put on hold for *now*"

The widget I ordered yesterday arrived and it didn’t take too long (and one lost screw, I had a spare) to transfer my recent buy of a 2TB SSD from its USB enclosure into the widget that’ll see it living inside the case with a much better interface. The old performance numbers are in the last post (haha, that’s me shamelessly digging for an extra click for yesterday’s post!) and I’m happy to see a few orders of magnitude increase in performance. Numbers ?

Picture. We're looking at a series of benchmark numbers again for a solid state hard disc. More coming in the text.
Set speed to Zoom

So, looking at the numbers and comparing to last time …

Sequential read rates have gone up from the 40MB/s (megabyte per second) hard limit of the USB cable to 2765MB/s on reads and 4345MB/s on writes. That’s much closer to the theoretical performance of the drive, so I’m happy there.

The Randoms haven’t seen as similarly dramatic an improvement but I’m still very happy with 17 and 20 going up to 53 and 170. That’s still a significant improvement.

The Input/Output Operations Per Second have gone up from 4258 and 4913 to a massively impressive 13495 and 41717. That means it can zap backwards and forwards to find the right data before you’ve realised that the system has gone to the drive to acquire it.

The microsecond timer was good already at 234 and 203 latencys and is up an order of magnitude to 23 on the second number (74 on the first). So compare that to the conventional hard disc and it shows that the old system belongs in the last century.

The conclusion I take is that while you wouldn’t get the full performance out of the drive, putting an SSD into a USB enclosure is a perfectly acceptable way of adding a lot of space to a PC gasping for room. I was (mostly) happily running Starfield off the SSD-ina-box and Starfield will be notorious for demanding an SSD and not an older hard disc.

Jargon busty time … The newer solid state device drives are pretty much just memory chips, of the type that hold their state when the power is taken off. They’re ultra fast. The older ones are :

Picture. Technology. We're looking at the rectangular shape of an old style hard disc. There's a circular platter in the centre, with an arm reaching over. The "head" is on the end of the arm. The connectors are on the bottom.

The data is stored on a cylinder of round platters, which have coatings on top that are sensitive to the magnets in the end of the head. The head is on the end of an arm that will move to allow the head access to the full width of the discs. The thing is called a disc drive because the platters are shaped like discs. They’re spun up to usually 5400 revs per minute with faster ones going at 7200 revs per minute. The more revs, the faster the drive can get to the data and the quicker it can pull the data off the drive.

They were fantastic for the early days of computing but … there are a lot of drawbacks to this technology. Earlier drives would suffer from crashes, where the arm and head could contact the platter. That would dig a trench and pretty much wreck the drive. It didn’t happen too much though after the drives would park the head somewhere off the platters when the drive was powered down. It takes time for the arm to move, which means latencies on these drives are measured in milliseconds instead of microseconds. That makes a massive difference, especially with modern PCs.

And they’re pretty slow in pulling the data off too. That didn’t matter too much until around 10 years ago when improvements in processing speed meant we hit the limitations of how we stored data. (And perhaps some shenanigans by Microsoft too around the Vista times, which broke caching of data).

They did see us through a lot of decades though, going from the IDE drive in the picture through to EIDE, SCSI and into the SATA era. Lots of acronyms there …

IDE – Integrated Drive Electronics – the bits that make it go are on the drive and they’re connected up with a 40 wire ribbon cable. You could have two of these on a cable and the “Jump Block” would select between Master and Slave. There needed to be 1 Master on a cable. One really silly drawback here was that the Heads, Cylinders and Sectors values were mismatched between the various parts of the electronics which put an artificial (528MB) limit on the size of the drives.

EIDE – Extended Integrated Drive Electronics – saw an end to that limit through some nifty translation. It also saw 80 wire ribbon cables come in to the same connector. The extra wires provided shielding to stop the signals in each wire transferring over to their neighbours. IDE and EIDE both used parallel or many wires to make them quicker, which was ok up to a point.

SCSI – Small Computer System Interface – was a competing and much superior interface from around the time of IDE. If I remember right, it could handle 8 drives on a chain, was much quicker and because it didn’t have that Head, Cylinder and Sector limit, could handle much bigger drives. But it also needed an expensive controller card at a time when we needed the scarce room and resources for sound cards and graphics and a SCSI set up would add a zero to the cost of a machine. SCSI died out when SATA appeared.

ATA and ATAPI – was the logical side of the interface. It stands for AT Attachment, with AT being the original IBM PCs. From the 80s. ATAPI stands for ATA Packet Interface, where the blobs of data would be parceled up into packets to bounce around the system. Here’s a link about ATA. We’re still using this original system for modern SATA drives.

SATA – Serial ATA – saw the 40 and 80 wire ribbon cables thrown in the bin in favour of one wire to rule them all. Ok more than one wire but instead of all the signals chattering to each other in the parallel wires, there’s just one signal wire. It meant they could crank up the speed significantly. EIDE was limited to 33MB/s with “Ultra DMA” (Direct Memory Access), my SATA SSD goes at between 300 and 500MB/s. SATA was also much easier to wire up than the PATA, the cables go round corners much better than those 40 and 80 wire ribbons.

Picture. Meme. We're looking at a chubby animal I think sitting in a tree. It's holding up a paw, with the captions being "WHOA !! Now that's too much information"

I’m probably letting the geek out a bit too much there. I did mean to drop a link to the site I stole the hard disc picture from though. Here we are, I’d be curious to hear which you think is more understandable, this site (linky) or my ramblings above.

There is another drive type, the nVME or non-Volatile Memory Express. This was an interface designed for how SSDs, instead of SSDs being shackled to the ATA system from last century. It’s much quicker. But apparently it’s also too new for my desktop machine to handle so the new drive is going to be just games and data. I’m ok with that.

To other things !

I mentioned I’m only “mostly” ok above … What’s up at the moment ? Headaches and a poorly back this week. I think I have answers for my outsides, I apparently have a light tomato sensitivity. Too many cup-a-soups, or pizza and I’ll see the impact on my healing outsides. But it’s not a serious one, I should be able to have the tomato soup or pizza in moderation.

I think the headaches are resulting from my latest pair of glasses. The test was done with a mask on in pandemic conditions, so there’s going to be alignment issues there. I’m sensitive to those, they cause headaches. It’s sad to have to retire glasses that cost £500 (two pairs, distance and reader) but I think I’m going to have to retire them early.

And the poorly back is just … a reminder of an older injury. It should improve but I’ll probably have to look after it for a while. I have the poorly wrist as well at the moment, which means I shouldn’t be testing the Starfield out on the new SSD arrangements … Conveniently, there’s good streams on at the moment so those have my attention.

On that note … to the streams ! Nite all. Hope the geekiness isn’t too weird and obscure this time.

Hello everyone,

I had the idea to look at tech again.

Picture. Meme. We're looking downwards at a black dog and a shaggy brown haired dog. Their mouths are open. They are eager. They are looking directly at a grille with cookies on. The caption "We are here to delete your cookies".
Do they mean Deleat ?

I’m not in danger of going for any serious PC upgrades any time soon, although I did acquire a nVME solid state device disc drive that caused me a little bit of grief. If you remember back a couple of posts, my desktop PC has the following disc drives lurking inside :

It boots off a 500GB SATA m2 SSD, which works very nicely. It just doesn’t have the space for games like Starfield and now Forza Motorsport which each take 120GB. Yep. Chonky.

There’s a smaller SSD in there as well but I don’t use that one any more, just haven’t removed it.

I have two active conventional hard discs, an older 1.5TB drive and a newer 3TB drive. That’s where the games and the multitude of memes go. It’s actually a bit of an accident that they’re both active, I copied the contents over but forgot to update the linking of one of the drive partitions.

(A partition is where you split up the drive into sections. It used to be handy in older times, not so useful now, plus it’s how you would split up Windows and Linux installations)

And then there’s the 2TB fast SSD hanging out the back of the machine inside a USB enclosure. It works much better for Starfield, which is much more playable on that drive. It’s still got issues but not nearly as many as if you try and play it on a conventional hard disc. What’s the issue there ?

Picture. We're looking at a benchmark result for a hard disc. It's showing the Read and Write speeds and a mixture of both. More info coming in the text.
For a 3TB conventional hard disc

These will be results taken last month. That first one is for my 3TB conventional drive. The things to look at there are the 158ish for the SEQ1M (sequential access?). That’s how quickly the machine is pulling the data off the drive. The IOPS is for Input/Output Operations Per Second, giving 166 on reads and 423 on writes. The RND4K is the time in microseconds it takes the drive to start doing its thing. The read is higher on almost 6000 microseconds, the write is quicker at 2356 microseconds. I think the difference there is because on a read, the drive has to find exactly what you want. On a write, it’s just looking for spare space. It doesn’t care what’s in the empty space.

Picture. We're looking at another benchmark output for a hard disc, this time it's for a solid state device drive. More info coming in the text.
Results for my older SSD

Those are the numbers for my older SSD, which is installed in the correct slot in the motherboard. It’s a SATA disc, which is why the numbers for Read (516) and Write (442) aren’t particularly high. Where all SSDs shine is in the IOPS, where it’s doing almost 10,000 reads per second and 16,646 writes per second. It’s taking 103 microseconds to find everything you want. That’s important if all of your information is either spread into many little files or if you need to find just the right bit of information. Starfield is crippled when it comes to the voice acting, it needs that fast to find thing in order to do voices without massive pauses.

Picture. Another hard disc benchmark result. This time for the new drive that's installed in a USB enclosure. More coming in the text.
Results for my new SSD that’s in the wrong place

And last one, that’s the results for my nVME SSD that’s currently in an external USB enclosure. It’s doing fairly ok in that box to be honest. It’s seriously crippled by the USB interface (it’s not the fast one) but the 234 microseconds for the Random Read is still exceptional compared to the old style hard disc. The 40MB/s read and write is showing where everything is limited by the cable it’s squeezing the data through. I suspect the data flooding the cable is also why the Random Input/Output Operations Per Second is only around the 4000s as well.

I’ll be curious to see how the new drive does when it’s installed in a widget that’ll let it go full speed. That’ll arrive tomorrow for installation in the evening after I finish up work.

As for curiosity, I did a check on PC prices again last night. But instead of looking at similar devices to what’s in Meltdown, I looked at the Intel options instead. What I noticed surprised me a fair bit but it backed up something I noticed with the AMD machines.

(Jargon busting – there are two competing computer processor makers at the moment, they cost about the same but I went with AMD because they are apparently technically superior now, that’ll vary over time)

The surprise comes from the hardware makers moving on really quickly from older technology. Meltdown is based on a 4 year old Ryzen 5 3600 processor that fits into a X570 chipset motherboard. What’s a chipset ?

Picture. We're looking at a block diagram of a computer architecture. More coming in the text again.
UNLEASH THE NERDISM

What are we looking at there ? The green blob is the processor and the chipset’s job is to martial all of the data going around the system. To the left, we have 3 orange blobs talking directly to the processor. That’s for PCI (Peripheral Component Interconnect) Express lanes that couple the processor to the graphics card. There’s a huge amount of data going through that link. There’s also huge amount of data going to hard discs and USB devices. The chipset comes in over to the right, it handles everything else like your keyboard, mouse and any controllers. It also gives access for the other drives in the system or in the olden days, things like dvd decoder cards or sound cards. Oh ! Chipset is how the sound chips in the system connect up.

Each type of processor has a specific set of chipsets designed for it, usually a good one and a budget one. The good one for my Ryzen 5 3600 third generation of that type is the X570 chipset. I could put a newer 5th gen Ryzen 5 5600 processor in there if I wished to. But … there are only 3 of those listed on Scan today. That means the manufacturers have effectively put it in the bin for the newer model.

It’s the same with Intel, there are only two of the older Socket 1200 Z590 boards available (ok there are more but they are double the price). There are 64 (sixty four) of the current Socket 1700 boards available.

So yeah, the old systems have gone in the bin even though the processors for them are still very available.

It was a curious and a little bit eye opening check realising that yesterday. What does it mean though ? Firstly, you have to be really careful about what you buy. Going for that slightly older 2 year old Socket 1200 cpu will give a massive problem in finding something for it to fit into. It’s been put in the bin for the 13th gen Socket 1700 chips released in October last year.

That’s a fun one for anyone thinking about obsolescence by the way … I might know some of them :-D.

Secondly … if you don’t care about obsolescence issues, then it can mean that it’s a PERFECT time to buy. The processor in my one year old laptop is an 11th gen laptop chip. Acer could well have been giving the big discounts because they needed to dump the stock while they thought they could.

So that’s the lesson I picked up … keep an eye on the market, sometimes opportunities come up because the people who make stuff are shifting from one product to the next and they want to dump the old stuff. Meltdown got put together when it did because AMD had just come out with a very superior product. The Dwagonsong laptop was bought because product change had led to huge discounts.

Picture. Meme. We're looking at a cute little white dog on a sofa, with paws on a laptop. The dog is wearing a sweater and a red and white bobble hat. The caption is "If you don't want me to shop online, you really shouldn't use my name for all of your passwords."

Quite. I think that’s enough for me for today, back to watching Billietrixx (Twitchy link) while she’s still on and then I’m somewhat grinding through the first book in the Silo series. I’m not quite sure what to make of that, the pacing feels off compared to the other books I’ve been enjoying far more. It feels hugely padded with a lot of character introspection which I don’t think exactly adds much.

We’ll see. Good night everyone, enjoy your books, your music (Dire Straits Making Movies track now – Expresso Love) and the rest of your evening.

And there’s a thought … (adds Dire Straits Alchemy to the wish list)

PS Forgot the feedback thing … The Novotel from Sheffield started badgering me for feedback … so they got feedback. It wasn’t the feedback they wanted. (TLDR – got nickel and dimed on extra charges, go with the competition instead)
