Have rock
  • I think the invention of engineering is what finally broke evolution, but there are a lot of factors we have that bootstrapped us to that point. Walking upright on two legs is more efficient at the price of raw power. Many creatures can outrun a human but no land animal can come close to our jogging range. A Cheetah can go 60 miles an hour for a minute or so but a human can go 10 miles per hour for 6 hours straight. It also frees our forelimbs, already made flexible, versatile and dexterous by our distant tree swinging ancestors, for tool use. Funnily enough, another ability that is unparalleled in nature is our ability to throw things with accuracy and power. You also need pretty good hands to master fire, and thus cooking, and thus unlocking extra nutrients from the food you catch, which provides for that very hungry brain of ours. A few millennia later and we've pretty much got control of the biosphere itself.

  • It already has.

  • I liked Fusion 360, I like Onshape - but I'd rather like something that I won't lose over the whims of one company. So, what?
  • Oh man "extensibility" in FreeCAD. The documentation is non-existent, is the main problem. It's just about impossible to understand how anything works, it's like trying to figure out how to run a battleship by turning cranks and seeing what they do.

  • In the US, did Amazon kill the mall, is everyone too broke, or a combination of other factors?
  • Amazon certainly helped.

    The stagnation of several anchor stores like Sears also helped. Sears was in serious decline well before Amazon became a major player in the market.

  • 40 Kilobyte Rule
  • A jpeg image is designed to hold any photograph. It can potentially display millions of colors, and needs to contain that data for possibly millions of pixels of on-screen data. Jpeg image compression does save some space compared to a bitmap which is literally 3 bytes of color data for every pixel in the image, but there's only so optimized it can get before it can't be used to store any possible photograph.

    The image above is 500x321 pixels with 32-bit ARGB color; so each pixel not only has independent red, green and blue data, but also 8 bits of transparency data.

    Super Mario Bros runs on the Nintendo Entertainment System, which has a working resolution of 256 x240 pixels. It has the capability of displaying 25 colors on screen simultaneously out of a total possible palette of 54 usable colors. It draws the background and foreground layers as "tiles" so you can store whole tiles in memory and then repeat them, and then on top of that it can draw hardware sprites which is how things that move more on screen like Mario, enemies etc. are made.

    Things like the animations of the question mark blocks which seem to shine or blink a bit, that's done by cycling the colors that the sprite is being drawn with. Big Mario and Fire Mario are the same sprite but color swapped. The bushes and the clouds are the same shape, but different colors. The super mushroom and power mushroom are the same sprite but different colors. The underworld levels are just different colors on the same sprites as the overworld.

    The sound chip on the NES is very simple, it has five voice polyphony and can make two square waves, one triangle wave, one hiss-like noise, and one PCM sample sound (not used to my knowledge in SMB1; it's how the steel drum sounds in the SMB3 sound track were made) and so what is stored on the cartridge for audio is more like sheet music than recorded sound. An mp3 file of the Ground Theme would also likely be larger than the entire game.

    SMB1 is also just...a VERY primitive game. It cannot scroll vertically (SMB2, the one that's Doki Doki Panic in Japan, it can scroll vertically OR horizontally but not both at the same time; SMB3 could do both at the same time as showcased by the raccoon tail powerup, but it required a RAM expansion built into the cartridge) It can't go backwards because it doesn't record the state of objects that have scrolled off the screen. It has no save system or even a password system.

    Finally, the game was made in 6502 assembly with the specific hardware of the NES in mind; which saves a lot of resources compared to all the abstractions needed for higher level languages and their abstractions.

  • You know what both of those films are? Exactly what their creators set out to make.

  • Fuck up a book for me please
  • Are you seriously going to try and pull some smug insufferable “everything is art” bullshit here?

    No, I'm more saying that "art" has no useful or stable definition especially as you are trying to use the word, to contrast "just entertainment" from "real art." I don't believe a line can be meaningfully drawn between those because lots of creative works have found themselves on both sides of that line depending on when they are in time.

    Using Shakespeare as an example, he and his actors thought they were making plays that would be enjoyed by the few hundred or maybe few thousand people who would show up to the Globe theatre during the few weeks they were performing a particular play, and then never again. They weren't setting out to make immortal classics for the ages and none of them lived to see that take place. When did Shakespeare's plays become "real art?"

    I don't think JRR Tolkien intended people to take The Hobbit as seriously as they do today.

    George Lucas didn't think he was making a century-defining masterpiece on the set of Star Wars.

    There is nothing preventing a future where massively anachronistic misinterpretations of the shooting scripts for eight episodes of Two And A Half Men become required reading for all teenagers 200 years from now as time transcending, culture defining classics.

    On the other hand, what brilliant works are forgotten because they failed to find an audience in their time, or they became a meme and burned out?

    The only honest criteria you could present to me for what makes "real art" different from "just entertainment" is the court of public opinion, which is subject to change over time. I live in a world where huge budget movies are based on stories and characters that originated in pulp magazines and penny dreadfuls.

    I'm not interested in trying to draw a line between "this is just entertainment, feel free to view this in whatever abridged format you like" and "This is real art, so I demand you undergo whatever effort is necessary to experience it in what I consider to be the original and correct format, I don't care what your priorities are or how much time and effort you can budget to this project." I don't see a functional difference between an individual reading a version of a classic book that has been abridged by AI and watching the relevant episode of Wishbone. There's someone alive today who only knows The Tempest or Cyrano De Bergerac as the version with a Jack Russell terrier in it. Who are you to say "No that's not good enough"?

    As long as the original works continue to be available I have no problem with any method of abridging them, and I don't believe any work is above consuming in abridged format for whatever reason especially on accessibility grounds.

  • See at some point this discussion starts to feel kind of up itself. @roscoe@roscoe@lemmy.dbzer0.com casually created a dividing line between "books that are for entertainment" and "real literature" but balked at marking the location of that line. "Don't be obtuse."

    I genuinely don't think that line exists. Shakespeare was the Netflix Original of his day, and his day was some 400 years ago. A lot of "real literature" is labeled as such basically on the authority of generations of pretentious twats, at least a few of whom basically think "old = good and new = bad."

    We translate works from one language to another all the time, you think the precise nuances always make it through that process? We also adapt novels to film or television as a matter of routine. The original post uses the example of The Great Gatsby, which has at least one film adaptation. Is that a perfect 1 to 1 transfer of the author's intent? Then you have retell

    Beyond this, if I understand correctly, this could be used interactively. Say you're using this on an e-reader, you could have the original text in the book, and then have a "what the fuck does that mean" button you can push to get an AI powered simplification if a sentence is too complicated for you or you don't understand a particular idiom or something. I bet there's someone out there who reads English as a second language generally well enough for The Great Gatsby, but doesn't get the colloquialism "turning it over in my mind." Hell, I'm a native English speaker and I could use something like that for a lot of works over 100 years old that use obsolete language I'm not familiar with.

    Or...there's this book called Congressional Anecdotes by Paul Boller, who writes in a style that is trying to be more clever than he is. Instead of saying something like "Senator Grug from Montana called Senator Flub from Wyoming an idiot, and that made Senator Flub angry" he instead writes "The esteemed member from the Gold and Silver state referred to his colleague Flub as a man of dubious intelligence. This didn't sit well with the senator from Wyoming in the slightest measure." I got just far enough into that book before giving up on it to recognize when an author on Cracked.com basically plagiarized it for an article. I mentioned it in the comments and the author messaged me like "Hahaha shutthefuckup" That book needs an AI simplification like I need a good night sleep.

  • You could say the same thing of the NES. The crash of '83 had as much to do with the mountains of shovelware on the market for the early consoles and microcomputers that might not even load and run. You got a lot of knockoffs, branded merchandise, and other low effort crap the programmer didn't actually give a shit about flooding the market, which inflated the bubble, then it burst.

    A large part of Nintendo's strategy for entering a crashed market was to address this with their Seal Of Quality. Using anything from the design patent of the cartridge shell to security chips, they enforced a monopoly on manufacturing cartridges for their systems; Nintendo was the only manufacturer of Nintendo cartridges. And their Seal Of Quality meant they had inspected the game and made sure it is functional software, that it loads and runs without crashing. They don't guarantee the game is fun, which is why Superman 64 was allowed to be published. It's a garbage game but it doesn't crash an N64.

    Other platforms aren't as strict with their libraries, which means there's more and cheaper games out there for it. The extreme example is Steam on PC, where their algorithm is "publish whatever is submitted and pull it down if someone raises a legitimate complaint." There's a lot of great games on Steam, there's a lot of Unity tutorial projects on Steam. Their excellent refund policies make this acceptable.

  • BackInTime turns on my monitors

    I use BackInTime (which is basically a front end for rsync) for backups, and I run one every night at 1 AM. This is on Linux Mint Cinnamon. If the computer is locked/the monitors have gone to sleep (computer isn't suspended), when the backup begins the monitors turn on, and will then stay on all night. I don't want to waste the power or wear out my backlights.

    How can I stop it from turning the monitors on, or how can I get it to turn them back off?

    I built a table for my porch

    I posted this one to !woodworking@lemmy.ca too, as I do most of my furniture projects, but I'm particularly proud of how this one came out. Solid white oak with genuine mortise-and-tenon joinery.

    A shaker table for the front porch

    I'm working on replacing my porch furniture, and the side table was the worst of the lot so it got replaced first.

    I've built a few little tables by now and I've got a lot of the process down. I used this one as an excuse to practice making actual mortise and tenon joints instead of the loose tenons I've used in the past. The mortises that the center brace sits in were chiseled by hand, the others are routed.

    I'm thinking of making a couple outdoor-friendly morris chairs to replace those old iron ones. That'll be a minute though.

    [SOLVED] {TV series or movie unsure] two characters act out scene from Empire Strikes Back for young children

    I think I saw this in a youtube video taken out of context so I'm not exactly sure when it was made, or if it was a TV show or a movie. And while it could obviously be from any time after 1980 because it references Empire Strikes Back it felt 21st century to me.

    It seems to be a future post-apocalyptic setting, the power isn't on, everyone's dressed in rags, there's scavenging etc. and in a moment of down time two of the main characters act out the lightsaber duel from Empire Strikes Back to entertain the young children who live there, and the kids gasp at the "I am your father" bit.

    What's this from?

    Oak plant stand w/ intermediate shelf

    It's actually just friction fit together in this picture; as I type it's in the clamps as the glue dries. Tomorrow some final touch up sanding and the first of four coats of spar varnish, then a few decades on my front porch under a couple potted plants.

    There's an education in all this oak; it looks conceptually simple compared to the shaker tables I've done so far, right? IT AIN'T! Each leg cambers out by 5 degrees in both directions, and that tiny difference make this project SO much more obnoxious than a table with vertical legs. Laying things out accounting for that compound miter at the top and bottom is "fun." The upper and lower frame rails are no longer the same length, they're different but related lengths. That lower panel? Can't be installed with the frame assembled. Hell I didn't even bother attaching it in any way, it's just captive in there.

    Unlike the previous tables I've built that are held together with floating tenons, the rails are thin and fit entirely into mortises in the legs, which meant some chisel work squaring the corners of the mortises, so I gained quite a bit of experience with chisels here.

    But, another project nearing completion.

    I tabled again

    A simple shaker style table in white oak, finished with spar urethane and kitty approved.

    The breadboard ends on the panels were an education on this one; on the top they aren't strictly necessary, but I felt they were needed on the lower panel so that the movement of that captive panel wouldn't rack the legs. Found out I prefer making the tongues with a router rather than the dado set on the table saw.

    Using a shop tablet that definitely exists

    This is the follow-up to my previous post about a Linux tablet for my workshop. based on the suggestion by @yojimbo@sopuli.xyz , I went with a Lenovo Duet 3i, apparently also known as an 82AT and/or 10IGL5. Sprung for the Pentium version with 8GB of RAM. It has arrived, and I've got it set up to start using.

    The Hardware Itself

    For a shovelware-grade machine, it's not bad at all. I'm sure they were sold in big box stores as the budget tier barely capable of running Windows 10, which is why there's so many of them for sale in barely used condition.

    2 USB-C ports came in handy for charging and installing Linux from a thumb drive. The screen is surprisingly good for a machine of this price point, and it runs cooler than my cat.

    The Linux Experience

    SHOCKINGLY good. Linux Mint loaded right up, though I wouldn't recommend it on this machine. Cinnamon is not intended for tiny touch screens.

    Fedora KDE Spin ran quite nicely, but I ended up installing Fedora Gnome. I generally hate Gnome but for a machine that will run FreeCAD, a PDF reader and a web browser, maybe a calculator, it'll work.

    So far, I haven't found anything that doesn't work. It suspends and wakes from suspend, keyboard works, backlight controls work, both cameras work, auto-rotation works, keyboard works in attached and bluetooth modes, Wi-Fi works...

    I think I just saw that graphical glitch @yojimbo@sopuli.xyz mentioned for the first time, I looked over at it and the top panel was near the bottom of the screen. Moving the mouse around seems to fix it, though yeah if that behavior continues or worsens I'm probably going to try either X11 or...something.

    Overall I'd call it "quick but not fast." UI feels responsive, but...put it this way I watched Neofetch run. Any disk operation at all is a bit slow.

    Gnome is...Gnome. I would hate to live in Gnome on my main machine. I think it'll do here; it's mostly navigable by touch screen.

    FreeCAD works amazingly well and is surprisingly usable on a touch screen, though to do anything serious you do need to be able to right click and use the Ctrl key. I think it'll do what I'm after. Going to start building a shelf either today or in the next couple days, will report back how it works in service.

    Looking for a shop computer/tablet that probably doesn't exist

    Let's see if I can keep this relatively short:

    I'm a woodworker, I do my design work in FreeCAD and then I print out my drawings on paper to carry out to the shop with me. It would be nicer if I had a shop-proof device to run FreeCAD in the shop with me because over the past year I found myself saying the following things in the shop a lot:

    • "Wait, let's go in and look at the 3D model."
    • "Ah dang I forgot to note this particular dimension on the drawing, let me go fix that."
    • "I'll measure this part up then go in and do some drawing."

    So what does "shop proof" mean exactly?

    1. Wood shop be dusty. Last year I hauled 250 gallons of sawdust to the dump. To me this means that a physical keyboard needs to be able to function if it's been packed with dust and/or needs to be vacuum cleaner proof. I also think cooling fans are probably a bad idea; a passively cooled device is probably preferable.

    2. Not many outlets in the shop, so it needs a good battery life. I actually don't need a tremendous amount of performance, I've used a Raspberry Pi 3 for the kind of CAD work I do.

    3. FreeCAD does not ship an APK so Android is no bueno, it's gotta be GNU/Linux.

    4. It needs decent usable Wi-Fi because I envision using Syncthing to keep my woodworking projects folder synced between my desktop and this device. It doesn't necessarily need to get signal out in the shop (my phone barely does; I lose signal if I stand behind the drill press) but it does have to connect to my Wi-Fi when I carry it into the house.

    I think this means I'm looking for an ARM tablet that can competently run Linux. Is there such a thing?

    ADDENDUM:

    Thanks to everyone who commented, I think I do have a plan of action: I'm gonna buy a used Lenovo!

    To answer the question I posed, no it doesn't seem that a Linux ARM tablet is really a thing yet. Commercial offerings that run Android or Windows on ARM are often so locked down that switching OS isn't a thing, the few attempts at a purpose built ARM tablet for Linux like the PineTab just are not ready for prime time.

    In the x86 world, it basically came down to 10 year old Toughbook tablets or 4 year old low-end 2-in-1s, and I think the latter won out just because of mileage and condition. A lot of the toughbooks out there will have 10 year old batteries in them, and they've been treated like a Toughbook for some or all of that time. The few Lenovo's I've looked at are barely used, probably because of how Windows "runs" on them.

    I'll eventually check back in with progress on this front. Would it be better to add to this thread or create another?

    Are conveyor lifts worse in Update 8?

    I mean, I know Update 8 ruined everything it touched and some things it didn't, but...I seem to remember being able to connect conveyor lifts directly between machines and splitters. I also seem to remember being able to reverse the direction of conveyor lifts while placing them. Neither of those seem to work anymore.

    I think I'm giving up until they've got the SMART mod working in 1.0. Playing this game without the SMART mod feels like playing in a sandbox, but every ten minutes you have to stop and count all the sand.

    End tables are finally finished.

    I guess I got the finish to look okay on the pine legs and such. Looks great on the oak tops and shelves. Sat down to draw these on Nov 1 and they're finally next to my couch.

    As far as I can tell, pine can't be finished.

    I've found my finishing problem: I'm building things out of pine.

    Traditional stain, gel stain, urethane, tung oil, danish oil...on oak, cherry or maple many of these look fine. No matter what I put on pine, it comes out looking like a septic prolapse.

    Do I actually need to do anything to go from GeForce to Radeon?

    My GTX-1080 is getting a little long in the tooth, I'm thinking of going all AMD on my Linux Mint gaming rig here, but...is there anything I need to do or install or uninstall to switch to an AMD card from an Nvidia one?

    I've never done this before on a Linux system; I've got my Intel/Radeon laptop, and my Ryzen/GeForce desktop and that's most of my Linux experience.

    There are emotions I don't know how to express without my glasses on.

    I emote with my glasses a lot. Slowly pulling them off in amazement, sarcastically looking over the top of the rims, etc. How do people who can actually see handle it?

    Which do you prefer: Handheld router, or router table?

    Until fairly recently I owned just one router. I bought it, immediately installed it in the table it came with, and it has come out of the router table exactly once since then to cut a couple slots. I have since bought one of those little "trim routers" but I still do the bulk of my routing work in the table.

    I'm curious, how do the rest of you prefer to work? Do you mostly use your router handheld or in a table?

    Recommend finishing products to me that aren't Minwax

    Minwax has ruined enough of my projects. I'm looking for recommendations for wood finishing products, particularly stains and wiping varnishes, that actually work, are readily available on the East coast of the United States, and are not manufactured by Sherwin-Williams.

    Journal keepers of Lemmy: Do you go back and re-read old entries?

    It's one of those things I've never talked about with other people, the most I've really been exposed to journal keeping in pop culture is Doug Funny. People don't talk about their personal journals.

    Ever since I was a teenager I've sometimes felt compelled to write about major events, and over the years this has become the habit of keeping a journal that I write in almost every day, and sometimes I go back and read old entries. "What was I doing this time last year?" I also sometimes keep notes or such intentionally for future reference.

    So, if you keep a journal, do you go back and read it? Why?
