WEEK THOUGHTS I haven't been finding much time for phlog posts this month. Partly it's just that the cold winder weather, relenting a bit now, has put me off spending long at the desk where this old computer lives (somehow I can't get into writing these posts on a laptop). Plus there's my usual issue of too many computer-based projects which means I want to use my remaining time in less computational company. I'm really not doing very well at finishing those things either. So, while the washing's going, here's another one of my condensed weekly thoughts run downs. DOCUMENTATION The Raspberry Pi Pico 2 was released recently and its datasheet is reportedly 1347 pages, up from 644 pages with the first Pico. This length isn't that unusual, and hard to compare fairly since many datasheets for microcontrollers/SoCs point at lots of other documents for details on specifics. But the trouble with this is that it's barely practical to even skim over the contents. Contents pages and indexes are often misleading, probably because the length makes them too hard to compile as well, what I think everyone does is just read a few likely bits and word-search for things they don't see. That's fine if it works, but when it doesn't you're left with wondering which of the 993 pages that you didn't look at has the info you missed, and how do you find it without spending days actually reading the thing properly? It's the same with standards. The Pico datasheet is now between the USB 2.0 standard and the current Bluetooth standard in length. All the standards for the Web now are endless. If you see someone mention that in a forum when they're trying to develop something then the typical response is "well of course you don't have to read all of it, just look at the bits on x, y, and z, starting on page 1825". But then in that it refers to something on page 1053, and you misinterpret that because you didn't read page 671, and you don't know about the simpler alternative system on page 284 which does all you need anyway. Oh, except in the example on page 2934 it's noted how that system is never used in practice anymore. Also since the writers then attempt to avoid all that confusion by summarising things, you end up with the document growing exponentially as each section begins with a summary of info in previous sections in case you didn't bother to read them. The only limit on this used to be the physical cost of printing these documents out, but since computers have eliminated that restriction it's able to spiral completely out of control. I predict a future where engineers all just ask AI what the standards say because nobody would live long enough to read them all, and entire hardware/software infrastructures are built wrongly based on the AI's misinterpretations, then nobody can make it work anymore when the AI is changed and starts interpreting correctly/differently. In fact that's probably already beginning. COMPUTER POWER The power consumption of the cloud has become a concern even outside of technology circles. I'm not sure how this can be so singled out though. It may be a source of growth in energy consumption, but theoretically physical resource efficiency should be one of the few real features cloud computing has going for it. People share hardware instead of each having their own. That's why it's cheap, no? If the VPS I use for my website is using tons of electricity, then the $1/month I'm paying for it must be making them a big loss after counting their electricity costs. Same with the disks storing its automated backups for free on Oracle Cloud. OK so it all adds up, and it's true that speculation about AI has funded a new surge of expansion, but surely the things that actually cost all of us money are going to be bigger net energy consumers than these cheap/free computer services? They can't really be the place to start saving the planet. More likely they're just something conveniently out of sight for individuals to point a finger at while still buying a new smartphones, cars, and overseas holidays every few years. TONER SCAVENGING I've been 'collecting' used toner carts, which I generate a fair few of through my business activities, for years. They have potentially useful things in them which I hate to throw away, not least the remaining toner inside since you can never use them up completely. A couple of weeks ago my power was off for the day so I finally pulled them all apart on my verandah. I tried not to make a mess, but it didn't work, and the rain hasn't really washed it away since, oh well. Pics of the result are here: gopher://aussies.space/1/~freet/photos/teardowns/toner_carts/ It took me one or two of each type of cart before I got the method figured out - the easy way often isn't obvious. My 3D printed COVID mask came back into service to stop me breathing in the toner that wafts out. Last time I tried to do it indoors, which whas a mistake - better to have a light breeze to blow it away. I think I got about enough toner to refill three of the smaller toner carts that I use, and which are easier to refil than the awkward big HP ones like the one shown in the first pic (I tried refilling one of those once and failed miserably/messily). The gears are cool, the metal rods/tubes should be useful, the scrws maybe handy, the other metal bits probably not so much but easy to store, the plastic shells... well they're a problem. While the toner cartridges were intact I could drop them off at a cartridge recycling bin. What do they actually reuse? I don't know, but _maybe_ they reuse the plastic. Now they're apart though, can I recycle them? The council website says they accept "rigid plastics" at one tip location (about 40min drive away, and shut at most times convenient to me), but I think they just mean HDPE, PET, etc. plastic bottles. These don't have any recycling code on them, so I don't know the plastic. They're obviously a thermoplastic so they _could_ be recycled, but it looks like I'd have to put them in the rubbish. Or I could resurrect my unfinished 3D printing filament plastic extruder project, but I never really ended up doing enough 3D printing to justify that, and there's too much big competition now to make a business from it (yes, this was another one of my aborted business plans, back when home 3D printing was new). So, environmentally, was this good recycling or bad recycling? Maybe if I'd dumped them all in a cartridge recycling bin the plastic would be reused, but I wouldn't have been able to use the toner and other parts. Maybe they would have just got out the toner and sent the rest to the tip anyway? Fact is that the toner saves me $60 in new carts (somehow I've never been able to find a supplier selling toner for refills cheaper than new toner carts themselves), plus the extra bits, so I figure the recycling method that saves me money comes first. It still doesn't quite feel right though. - The Free Thinker
