    The big thing I learned from this article was actually news from a couple years ago.

    Microsoft finally started supporting traditional win32 games in its store a couple of years ago (link), but this change alone hasn’t helped the Windows store compete with Steam.

    I'm not sure how I missed hearing about this. A lot of the issues I had with the store were really issues with UWP apps. It's probably worth another look, especially if the lower cut ends up translating to lower prices. I'm still opposed to linking my windows login to a Microsoft account though, and tbh I normally use Win10 LTSC, where installing Store is a giant PITA.

    Anyway, this is a big move to try and draw people to their store. I have to wonder if this is some desperate last-ditch all-or-nothing play in the last of Store's death throes. Aside from Forza and Office, I can't recall ever meeting anyone who bought anything from the Windows Store. It's funny to think now about how Valve ended up creating their own OS and encouraged a dozen PC manufacturers to make consolized PCs running SteamOS because they were so worried about the Windows Store being overwhelmingly successful.

    I do get that, and I suppose it's the same as reading physical books versus e-readers, but to me the loss of fidelity, the finicky, fragile nature of the media, needles, etc is in no way worth it.

    It's just, when cassettes became available I ditched my 8-tracks and records. When I found a fancy Technics cassette player at a garage sale in the late 80's that had auto-reverse and could automatically fast-forward to the next track I could never use another tape player again. I did enjoy interacting with these old clunky machines, but I feel like the formats of the day did interfere with my enjoyment of the music.

    I have no nostalgia for analog media. As a media format, vinyl records are inferior to pretty much everything, and I can't wrap my head around the modern hipster LP scene at all. Cassettes are making a bit of a comeback, and likewise I can't understand the appeal.

    Books, I get. It's a tactile thing, there's a smell to old books, a certain weight to them, etc. For me an e-reader is close enough, but I get that some people can't replace the physical object.

    What I actually miss most is physical buttons, switches, dials, and sliding potentiometers. I miss being able to control things without looking, just by feel. I miss tactile feedback where at least I can bottom out the pot to know where the end of travel is instead of dealing with rotary encoders or worse yet, touch controls.

    I fully support any future hipster movements that try and bring back tactile controls in lieu of touchscreens. If any of your friends are trying to bring back 8-tracks or something, remind them how cool analog, tactile buttons and switches and potentiometers used to be. Try and make this a movement. Call it the "Kinetic Movement" or something. Tell people that touching switches grounds you or something. I'll bet we can make it a thing.

    David Lynch is really good for that, imo. Blue Velvet (1986) in particular really touched that nerve for me. It's set in this quant picturesque 1960's small town, but as it goes on you start to see the seedy underbelly that was just below the surface the whole time. I found it deeply unsettling, and I ended up wishing I didn't smoke a joint before watching it.

    White Zombie - Black Sunshine

    Johnny Cash - General Lee

    Chuck Barry - Route 66

    Carpenter Brut - Turbo Killer doesn't really have any lyrics, but it does have a music video, which isn't even really about cars, but it's pretty awesome, and has cars in it.

    While we're on that aesthetic, the Drive Soundtrack isn't really about driving, but it's great music to drive to.

    Could you explain this a bit more? I'm not sure I understand. The API itself is nothing but a list of function names and expected behaviour from those functions, no? The implementation of an API is kinda a no-brainer as far as being copyrightable, but I thought it was the literal names of the functions that was in doubt.

    As far as I understand it, google copied 14,000 lines of code declaring the names of those functions, and wrote the other 2mil+ lines of code themselves, which implement those functions. Taking 14,000 lines of code verbatim should be a no-brainer copyright infringement, but in this case it's considered fair use since it's just the names of functions, not how they work.

    I thought the real danger here was Oracle being able to say they own the names of variables and functions, and implementing your own String.toUpper() is copyright infringement. Even if your code is written from scratch without looking at Oracle's, the declaration itself would be infringing.

    Haha, it's like you read my mind. I've been watching a lot of Adrain's Digital Basement on youtube lately, so oldschool hardware has been on my mind recently. Shortly after writing this I actually thought about the 1541 and how it technically had more processing power than the C64 itself and ran its own OS, and thought about how I'd edit that into my comment. I ended up saying "fuck it" and hoped someone would come along mentioning that.

    Yes and no. Most devices we think of as peripherals are what we would describe 20 years ago as their own computer, with their own CPU, RAM, storage, etc, running a software stack which may or may not be sufficiently complex to call it an OS. For example my mind was kinda blown when I realized the microcontroller on a hard drive was actually running VXWorks, and if you plug a serial port into some unused pin headers you can listen in on the hard drive's own internal bootup process.

    It was at that moment it clicked and I realized that for the last 15 years devices have been largely whole computers. The device isn't "natively" speaking SATA. It's a whole computer booting up and using SATA as its networking interface to talk to the host system. This was cemented when I ran into this article where legendary hacker SpriteTM installed linux on a hard drive. Like I mean, he installed linux, on a hard drive... As in, he managed to boot the linux kernel on the hard drive's internal microcontroller.

    But no, linux isn't common for these things, or if it is we don't know because the mfgr hasn't documented it or complied with the GPL license. Often they'll use closed-source proprietary realtime operating systems like VXWorks, or maybe they'll use the Mach kernel and BSD userspace in order to avoid releasing their source code. Security by obscurity is the name of the game in the embedded devices world.

    Linux is common on settop boxes, routers, NASes, etc, but not so much on tightly integrated cellular baseband modem chips, hard drive controllers, etc.

    I spent the last couple weeks being really depressed. My life has never been really stable, but lately, especially over the last year, due to current events it's been harder than usual. I've been hanging on, trying to stay positive, despite living in some unusual situations.

    Things are looking up though. I just figured out my housing situation for April yesterday, March 31st, which led to a huge weight off my shoulders today. I've got a room for the rest of the month, and I've got to make the most of it.

    I've just had so many instances of a great job being offered to me by an old friend across the country, only to have it pulled out at the last moment Charlie Brown style... It's been really discouraging.

    I think I'm going to just go and hitchhike off and work on a farm or something. I hear physical labour is in high demand in places that cost a lot less to live than where I am right now.

    There are a few other things I'm suspicious of in terms of longevity. I'm wondering if/how often you need to replace electrodes in the electrolyzer. There's mention of a battery in their block diagram graphic. It looks like the fuel cell doesn't directly power the electrolyzer, but it uses a dc-dc converter to charge a battery which does so. I've got to wonder, what chemistry is that, and what's its lifespan?

    The datasheet mentions 30 years as the maximum lifespan of the hydrate, whereas one full cycle per day every day for 30 years is 10958 cycles. How is that 20k cycles rating actually meaningful? The warranty is for 10 years. Can we expect this company will exist in 10 years? Can we hope that this company will be successful enough that replacement parts will be available in 10, 20, 30+ years? Otherwise, how repairable is the device, I wonder.

    As for power storage per volume, if you're looking at using hydrogen you might as well use compressed gas. As far as I can tell that's what all the hydrogen cars on the market are doing: https://en.wikipedia.org/wiki/Hydrogen_vehicle

    These hydrate storage things require a chemical reaction to occur where the hydrogen is fixed to metal ions or something. I'm a total layman here, but as far as I understand these reactions don't happen quickly, so there's a limit to how quickly you can charge and discharge them. This 40kWh unit can only output 5kW, which is enough to power an electric clothes dryer and not much else. Certainly not a car. If you were to double these up so you had 80kWh or roughly the same range as a tesla, you'd have 10kW to work with, or 13.4 horsepower. I imagine charging them with hydrogen isn't an instant thing either, and is actually fairly slow, which makes them work okay for solar, but unsuitable for use in a vehicle.

    I'd be less squicky about a hydrate in my car than compressed hydrogen, that's for damn sure. Yet, commercially designed hydrogen cars are on the market, and DIY projects have existed for many decades using compressed gas.

    If anyone wants a rough idea of the reactivity of these sorts of hydrates, here's a good video from mike's electric stuff on youtube: The "Upp" fuel cell charger. A completely pointless product.. At the 47m 20s mark is where he learns the item is full of fire, and at 48m 34s he dumps the whole thing out, where you can see the hydrate being angry that it's being exposed to oxygen. I'd still say it's less spicy than lithium ions in most cases, but in any case I'd be a fair bit more confident rolling around with that than compressed hydrogen.

    Anyway, sorry if I sound overly critical of this. I'd really love for hydrogen to become a viable storage medium, but I've been burned in the past.

    Whoops, you're right. I used ddg for currency conversion. I searched for $34750aud and what it gave me was $34750USD in AUD, which is the opposite of what I wanted.

    Edit: I figured it out. Any time you use "$" before the number it assumes USD. If you search for 34750AUD it gives you the result in USD or maybe your local currency, but if you prefix it with $ like "$34750AUD" you get USD-to-whatever.

    The most interesting thing about this I think is the cycle life. They claim the hydride will last 20,000 cycles, which is really impressive compared to lithium batteries which typically have lifespans in the low thousands of cycles.

    That said, the cost is pretty crazy, and I'm not sure it makes sense yet. A powerwall 2 is $6500USD, and has 1/3 of the capacity of one of these. Three powerwalls is $19500, versus this thing is $34,750. I'm going to assume those are AUD, so that's nearly $44,000USD (edit) $26,500 USD. Now you might say, this thing is rated for 4x the cycles of the powerwall, and sure that's a great point, but if you're throwing out nearly half of your solar energy due to inefficiencies, you need to buy nearly double the amount of panels and suddenly this isn't making a lot of financial sense.

    They aren't. They're just the most enthusiastic about doing it. I can edit tags, titles, and move posts between groups. I just rarely do so unless I see an obvious typo or someone requests moving a topic. I can rarely get to a post before mycketforvirrad tags it though, so I pretty much defer to their judgment.

    Anyone can request these permissions. The eventual goal is to have these powers granted semi-automatically, but the mechanics of that are still up in the air.

    It's not easy to find but this is actually mentioned in the docs. At the bottom of the Instructions - Posting wiki page there's a link to this thread where those permissions are explained.

    As for actual style guides and editing standards, there aren't any. It's really up to the person doing the editing and tagging to use their best judgment. Tags have more guidelines than titles, and the docs do explain that to some degree. It's worth noting that the docs say this about tags: "If you don't enter tags on your topic, someone else will probably come along and add some for you!"

    It was a bit more like Visual Basic, with a WYSIWYG editor that was more like a modern Microsoft Office product than any Microsoft Office products of the time. The usual way it was used back in the day was as a slideshow program, ie: Powerpoint. It could also do some embedding of other programs' data, a la OLE on windows.

    It ended up being capable of a lot more than it was intended for, and people were creating entire games in it, which weren't just choose-your-own-adventure stories. The scripting language behind it, HyperScript, was a lot more capable than the original designers imagined, and there ended up being very sophisticated programs, games, and demoscene demos created in it.
