To speak to a "long perspective" on the issue, that was one of the things that scared people when electronics moved to integrated circuits. There's no "knowhow to keeping them alive". Once the magic smoke gets let out, they're just dead.

There was a time when every part of a computer - including, literally, an individual "bit" of ram, could be hand-repaired, craftsman-style (and even visually assessed for failure), but we've been on a long, long trajectory towards none of this stuff being user-serviceable.

We're now watching the rise of SoC, wherein my graphics card and my ram crawl into my CPU and disappear as discrete components. Strange times.

This can still require a certain amount of DIY.

I've just replaced a Blackmagic Atem Mini: sadly, I tinkered with my previous one trying to keep it alive and couldn't return it. I burned it up trying to do too much with it: ran the internal processing at super HD from a Pocket Cinema 4K, with two separate other inputs coming in and having to be rescaled, color corrections, and then the output downscaled after chromakeying to HD.

The unit basically melted itself until all it could do was flash bright colorful lines. Total loss.

So the replacement (dropping right into the previous workflow, though I'm making a point to not run as many rescaled inputs by default) will sit on a homebrewed heatsink with thermal pads and fan. That way it probably won't burn up, but if it did I won't have taken it apart, and I can most likely return it for a replacement.

The inability to repair is a concern, but on the other hand building the larger environment into the cooling support the unit should have already had, is the DIY aspect. Should work.

Well, I get your somewhat nostalgic attitude. But back then, computing equipment was also way large, louder, and energy consuming. Heck, one of the "museum" disk drives we have at work used to make the light flicker in the lower floor if you powered it on. So yeah, we're past a certain point of repairability. Thats sad, but more a function of progress, not really something we can do about.

But that doesnt mean all our existing tech will emit the magic smoke in the next few months. The endless need for more computing power is mostly driven by software bloat. We could extend the current smartphone and gadget usefulness by a significant amount of time if we stopped to fall for constant featurism and did lets say, a year or two of cleanup. Sure, "the future" like AR and such will have to wait, but heck, this "we will sell you 3d" thing is around since the 80s and didnt take of in the mainstream yet, so what?

If we kept our tech level at around the 80s but only increased the power efficiency, we wouldn't be in such a bad position.

We couldn’t really have achieved this degree of power efficiency on 80’s tech though. Likewise, we couldn’t have gotten to 2020’s tech (always-on wrist-watch displays that last days), without increased power efficiency. Advancements in either one facilitate advancements in the other.

As a fun example, I’ve been simulating core memory at the level of electric/magnetic fields lately. It takes literally trillions of floating point operations to simulate just 1 nanosecond of a single bit of core memory. In doing this, I can identify things like “if we were to arrange the cores like <this>, we could reduce the peak magnitude of the radiated fields when a core flips, thus we could get by with using slightly softer ferrites (which use less energy when switching state) without encountering noise problems.”

But of course, a trillion fp operations was a lot more back then! Having more advanced tech made it substantially easier to optimize the earlier tech. Optimizing compilers are maybe a more direct, but limited, example of this. The faster a CPU can run your code, the more cycles you can have your compiler spend making that code run even faster. I’m not sure there’s a good term for these “mutual feedback loops”, but they seem to pop up a lot.

Aren’t most of the power efficiency gains from integration and miniaturization? If you’re charging/discharging a larger amount per bit, it’s going to take more power than a smaller (physically and electrically) equivalent would. That tends to work against practical field repairs (other than replacing at the IC or subassembly level).

The shorter the distance between two components the less energy you're going to lose to resistance, electromechanical components have physical friction, conversion inefficiencies going from electrical to mechanical energy, and the energy needed to accelerate a mass.

Really, what nukes the repairability of a lot of products these days (ignoring the repair-hostile practices of many companies) is the cost of the item vs the time needed to disassemble the unit, track down where something went wrong, repair it, reassemble, and hope that component didn't blow because something else upstream is faulty that you didn't find. Cuba and Africa the time is cheap while replacement units are somewhere between expensive and unobtainium, USA/Japan/Europe not so much.

If floppy drives were common today I think many of the issues you highlighted like increase power usuage would be solved and applied to this domain. We don't have to be past that power.

Are there any standards bodies or informal organizations that try to quantify software bloat and featurism? Seems like an opportunity for groups that are motivated to keep software lean and consumer friendly to pool some resources ala open source. Anything like that out there already?

> if we stopped to fall for constant featurism and did lets say, a year or two of cleanup

I hear that all the time. Usually, in the same paragraph, they'll also ask for Feature X, Y and Z.

> I have enough HW and can live a few years off what is there. I guess people have been trained to get the newest thing every year

I imagine the downvotes were for implying that everyone else is in a similar situation as you. What about people who were being efficient before the shortage, and now can't keep their aged equipment running any longer? What about businesses who suddenly need much more equipment than they did previously, due to pandemic restrictions?

> How is the market for used equipment doing btw?

I've found it much harder to find available supplies at any given time, but I haven't actually seen prices going up as a result.

>> How is the market for used equipment doing btw?

I sold my stockpile of laptops (anything i5 or newer) for triple it's value last year. People would buy anything at that point.

Crazy. And also good, since that hardware is likely getting used more now.

Have you never had a laptop stolen or a phone destroyed by water damage or a car totaled in an accident? Sometimes you actually need a replacement, and when you do, you need it now because you depend on it for your livelihood. Buying new is not always the mindless plodding on the capitalist treadmill you make it out to be. There are plenty of people who can and should delay purchases right now, but there will always be those who just can't wait.

There's definitely a sort of "keeping up with the Joneses" that goes on in technical fields with regard to hardware. I do all my personal projects on a 2013 model Ultrabook. Sure it's underpowered, but not for editing text, compiling small codebases, or building CRUD WebApps. If I need to do some derp learning, I can just spin up a cloud instance. There are certainly productive tasks that benefit greatly from newer hardware (video editing, compiling the Linux kernel, launching a single instance of the Android Studio emulator), but most of this hardware capacity is probably for gaming and, like many people, I'm not much of a gamer.

Since I am still mostly on a plain terminal, I used to have a time when I used a rpi0w as a laptop, since I really dont need much more then an instance of Emacs and a few ssh sessions in a tmux. I switched to a real laptop by now, and its nice to have a bit of local power. But I could actually do all my dayjob on a rpi0w.

What's HW in this context? I can only think of homework and hot water, but neither makes sense.
