no, i don't think i will
  • You absolutely cannot go meet them. They are kept in an extremely sterile environment because, in order to be the most appropriate for transplant, their immune systems are turned way down.

    Source: some youtube videos I've seen, in the science/education space. I don't recall the exact channel.

  • I say it's definitely without a doubt a reference to the holocaust, but I can't say what the joke was supposed to be or what the author thinks about the actual holocaust.

    Seems like the man gets very angry the second he realizes he's making a bug holocaust. Is that funny?

  • site isn't loading for me, but I'm guessing it's one of those "combine two things to get a new thing" games like Doodle God, but with AI answering on the fly instead of it being handcrafted?

  • Yup, the .text "file" is binary, and I assume it's exactly that - the executable machine code - but I did not try opening it with any hex editor or disassembler. I tried with a text editor, knowing in advance that it's going to fail, and it did - there were a bunch of null or error characters shown and the editor crashed soon after.

    I honestly didn't look any further into it, because I just don't care. Archive Manager apparently just splits up the sections of the .exe and exposes them as if they were files in an archive. Seems as useful an approach as any.

  • blahaj
  • I'm assuming Unicode anyway, and UTF-8 is by far the most natural because most files will be in ASCII. A "normal form" (see link above), you might think of it as a canonical form, is a way to check if two strings are equivalent, even if they encoded the text differently. Like the example mentioned on Wikipedia:

    For example, the distinct Unicode strings "U+212B" (the angstrom sign "Å") and "U+00C5" (the Swedish letter "Å") are both expanded by NFD (or NFKD) into the sequence "U+0041 U+030A" (Latin letter "A" and combining ring above "°") which is then reduced by NFC (or NFKC) to "U+00C5" (the Swedish letter "Å").

  • Well, I did get my hands on an exe file (some game on Steam) and opened it with Archive Manager. It does show some files, but the file properties say Type: application/x-ms-dos-executable (as opposed to application/zip). So it's not an actual archive file, the archive manager is just displaying it as such to be helpful.

    The "files" I can see are:

    /.text
    /.reloc
    /.rsrc/version.txt
    /.rsrc/ICON/2.ico
    /.rsrc/ICON/3.ico
    /.rsrc/ICON/4.ico
    /.rsrc/GROUP_ICON/32512.ico

    I tried to create a zip file and rename it to .exe, but Archive Manager failed to open it at all which I found strange. You'd think it would look at the actual file contents to figure out what type of archive it is, and not rely on the extension.

  • blahaj
  • Good point. Do filesystems use a normal form to at least prevent having two files with effectively the same name?

    I should point out the flip side though, that there's no avoiding Unicode in filenames. Users in languages that don't use the Latin alphabet (such as Japanese, Chinese, Korean, Hebrew, Arabic, Greek and Russian, and the list could go on) can reasonably expect to be able to give a file a name they can read and understand with no extra effort. All the software woes that come with it - too bad, software needs to deal with it.

  • blahaj
  • It's a zip file that includes a bunch of things, including embedded images and a bunch of other junk, but yes - the most important and central files in the zip are XML-based.

  • Present for the boss
  • I think with enough R&D into specialized balloon-manufacture techniques, it would be possible to make round balloons that inflate into a different discernable shape. But it wouldn't be as detailed or precise as in the comic.

  • Are they no longer making colored volumes of One Piece?

    The digitally colored manga was releasing at a relatively steady pace, with at least one release per year since it started in 2012, but after volume 99 in 2022 there's nothing. Does anyone know if they just stopped completely? Seems strange to stop just before volume 100.

    A woman is out shopping, and suddenly spots her husband

    A woman is out shopping, and suddenly spots her husband. As she's about to say hello to him, she notices the man is filthy: his clothes have stains from spilt food and drinks, his face and hands are dark with mud and grime.

    "What happened to you?!" she asks, skipping the hello.

    "Oh, it's nothing, don't worry about it..."

    "What do you mean don't worry about it? You're dirty like a pig! At least go home and shower!!"

    "No, I can't... There's something I have to do. Sorry, honey, I'll see you later tonight."

    "Well at least tell me how you got so muddy!"

    "I really can't tell you. It's nothing, I promise."

    The woman starts getting angry. "Listen to me. Either you tell me what's going on, or go home with me right now to wash yourself!! If not, I'm packing your things and kicking you out!"

    The husband thinks about it for a while, then makes a deep sigh and says: "Alright... I'll come clean."

    Interesting position with a safe square - can you find it?

    This was a rare moment where I actually had to think to find it. Can you?

    Screenshot is from a solver I found online because I didn't think to take a screenshot until I already opened the safe square.

    Is there a movie with a significant portion of it shot through a telescope?

    Or a very very high zoom to get a similar effect.

    No real reason for this question, just a random wonder I had. Basically the effect this would have on perspective might be interesting, and I wonder if any movie used this kind of shot for more than a couple of seconds.

    How does DNA decide the shape of the body?

    I know that DNA encodes proteins. Truthfully, everything besides that (including 'what are proteins') mostly wooshes over my head, but that's not relevant because whenever I search this question I never even find it addressed anywhere.

    The human body has, among other things, two hands each with five fingers, with a very particular bone structure. How are things like that encoded in DNA, and by what mechanisms does that DNA cause these features to be built the way they are? What makes two people have a different nose shape? Nearly everyone in my family has a mole on the left side of their face, how does that come about from DNA?

    I'm sure there are many steps involved, but I don't see how we go from creating proteins to reproducibly building a full organism with all the organs in the right places and the right shapes. Whenever I try to look this up, all of these intermediate steps are missing, so it basically seems like magic.

    As I said, any explanation will most likely go over my head and I won't be able to understand it fully, but I at least want to see an explanation. I'll do my best to understand it of course.

    What are these? They keep turning up on my floors

    I'm in the middle east in case that helps narrow it down. Very hot few days probably have something to do with it.

    Where are they coming from? Are they hiding somewhere in my apartment? They seem to be flightless. They are all the same size and very small, here's one on my finger for scale: !

    Proton Drive issues and woes

    Kind of an update from my previous post. The Proton Drive app on Android utterly failed to back up my photos and videos. I've now got a glimpse to a possible reason why.

    I realized that it was doing fine with photos and small videos but was struggling with large files, so as a temporary measure, I moved all the files bigger than 1GB to a different folder on my phone. I then had to wipe the app's data and log back in because it was just hanging or looping repeatedly otherwise. After logging back in, it successfully backed up all the remaining files over many hours. At least, I think it did - I'd have to go one by one to find out and I'm really not feeling too confident about it. But if it didn't get all of them, it got almost all of them.

    Then I added back in the files that were between 1GB and 2GB. It managed this fine. The app's data usage grew to about 4GB at some points but that is fine as it needs to create encrypted copies of the file it's backing up and it might be doing a few files in parallel. At the end, the data usage went back down to <1GB.

    Then I tried to add back the files between 2GB and 5GB. There were four of them: 2.25GB, 2.50GB, 3.86GB, and 4.12GB. Total size: approximately 12.73 GB. After setting the app running, its data usage grew to upwards of 60GB and I had to halt it. As before, there was no way to get the app to behave again after that besides wiping data and logging back in again. The "clear local cache" button in the app's settings did seemingly nothing. I moved the big files back to the temporary folder.

    Next I tried to move the files one at a time, starting from the smallest one. So one 2.25 GB video file. Turns out my phone shows base-10-based file sizes, so it's actually 2.091 GiB. The app misbehaves a little bit in vague ways that I didn't quite comprehend and can't explain, e.g. it got stuck at "3 files remaining" even though I only added 1 file, so I needed to wipe its memory again, but eventually it uploaded the dang file. I don't remember exactly how much data it used in the process, but the important thing is it worked. And then I looked at the file through the Proton Drive web interface and checked its details, where I saw what's in the picture:

    > Size: 2.09 GB > > Original size: -2049486257 bytes

    The original file size is stored as a 32-bit signed integer! Is this only in the web frontend, or is it also like that behind the scenes? What happens when the file size exceeds 4GiB? Does this only affect photos/videos or does it happens for the general-purpose Drive as well? Is this why big files have been failing for me?

    I'll keep you guys updated... And I hope these bugs are fixed. I still believe in Proton.

    Edit: the four files, added one by one, uploaded successfully. Now moving on to a 6.10GB file. This is bigger in bytes than 32 bits can represent. Wish me luck.

    Edit next day: the 6.10 GB file failed to upload. It's perpetually stuck at "1 item left" after giving it more than enough time overnight. The app is also taking up some 15GB of space - much more than it should. While uploading previous files, it gree to marginally larger than the file being uploaded. Now it's well over 2x that. So my conclusion is that Proton Drive for Android can't back up videos larger than 4GB, and fails catastrophically when attempting to do so.

    I'm already in contact with Proton support. I'm not sure I've quit convinced them of the severity of this bug yet (or multiple bugs) but they acknowledged that there are issues and suggested that the current beta version 2.4.0 of the app has mitigations regarding storage usage, and they gave me instructions for trying to access it.

    Proton Drive camera backup skips big files

    I upgraded to Proton Unlimited today and I've set Proton Drive to back up my whole camera gallery, a few hundreds of GBs, so it will take a while. But I noticed that it skips large videos, e.g. it skipped a 9.8GB video file. Is this intended behavior? I can't find documentation of it anywhere and it seems to happen silently. I easily could have missed it, assumed that it backed up everything down to a certain date, and deleted the only copy of the videos.

    How does Proton justify its free options?

    I joined Proton just a few days ago, and I'm paying for it so I can use my custom domain.

    I watched this interview and it raises a huge question for me (link includes timestamp): https://tilvids.com/w/q1mZzv6eq3iULLmGdV6w6M?start=6m20s

    In this interview, Andy Yen says about gmail et al "there's no such thing as a free lunch". Then, in nearly the same breath, he boasts that most Proton users don't pay, they use the basic service for free because that's all they need.

    So my question is: if there's no such thing as a free lunch (which there isn't), how come Proton can offer it?

    This is supposed to be solvable, but I can't find anything. Any ideas?

    Screenshot from Antimine on Android. It's supposed to not require any guesses, but I'm totally stuck. I'm probably missing something simple, so more eyes on it should help... Anyone?

    Can I install Ubuntu 18 software on Ubuntu 22.04? (Technically Linux Mint 21.3)

    Hope these kinds of questions are allowed here. On this occasion I'm just looking for a straight answer.

    For a university course I need to install ROS - software for doing robotics stuff. Specifically, I need ROS 1 - which is no longer being updated, as ROS 2 is now the focus. The installation instructions are here: https://wiki.ros.org/Installation/Ubuntu

    The instructions from the course material say that only Ubuntu 18 would work, though the ROS wiki says Ubuntu 20.04 is the target. Either way, it doesn't seem to be available for Ubuntu 22.04 and therefore Linux Mint 21, which is what I'm running.

    The course instructions generally gives 3 options:

    1. Install ROS on a VirtualBox virtual machine
    2. Install on Windows using WSL
    3. Install on a real Ubuntu 18 system

    Right now I'm going to use VirtualBox to get started, but I'd really prefer to run it natively and I'm worried about performance. Is there a simple way to download and run software intended for Ubuntu 20.04 on Linux Mint 21.3?

    Edit: thank you all for the great suggestions! I got stuck on an unrelated problem (ran out of storage space) but I'm sure your suggestions will work once I fix that. Forgive me for not replying individually, you're all awesome and I don't have anything to add other than "thank you" :)
