  • It’s my main issue I have with the whole topic. Starting in 2017 or so, there were so many idiotic promises regarding space travel and all, this one included. Oh yeah and we’ll colonize Mars btw. Like what are you people on? And now SpaceX is even behind on the contractual obligations to NASA, Artemis will not bring astronauts into moon’s orbit this year. Now while do acknowledge that space travel is really hard, this was achieved almost 60 years ago already. What was promised does in no way match reality. Going to Mars was always unrealistic, but to me it feels like progress on ambitious yet achievable goals is worse than 60 years ago.

    The mission was contracted for 2023, which already passed. I know SpaceX didn’t cancel it (why would they of they can just move the date into the future indefinitely) and that’s why I said they didn’t perform it. But the result is the same and the reaction of the client understandable. Any sane party will cancel a contract when they see that the other party is unable to fulfill their offer.



  • It’s not that far-fetched, PDFs in my opinion are closer to vector graphics than to document formats like odt and docx. They have no understanding of format if not using advanced features, like a table in a PDF is just spaced text with lines between them, and text is just independently placed letters. In fact the space symbol doesn’t exist in most PDFs, it’s just that two letters were spaced further apart. So they basically are multiple canvases that are being painted on with letters, lines, fill areas and even bitmap graphics.

    Modern PDF actually does further in the direction of a document format by providing the content in a structured way, mostly for accessibility, but also for making the format suitable for automatic processing the contained data.


  • I don’t think that’s what’s happening. There’s no hard requirement for cat to read everything straight into memory. It can send data once it’s available, and the receiving process can read it as fast as it wants. There are cases where this might be more clear: Let’s say you have a big video file that you want to convert to something that only supports like y4m input and is not in ffmpeg. A common way is something like ffmpeg -i infile -f yuv4mpegpipe - | encoder --y4m outfile - I’m pretty sure ffmpeg won’t read the whole infile into memory, nor will it store the whole y4m representation in memory. Instead, it will decode infile as necessary and push into the pipe at the speed the encoder can handle.

    But yeah, I remember something about tar using libraries for compression being more efficient that piping its output to a compressor. So it’s still the better route, but probably not as much better as you think.



  • They aren’t really designed to stop people from breaking in but rather to stop intrusive people that you talk to first before deciding to not let them in. With the chain, you can open the door a bit without allowing the person outside to force himself in without too much force, e.g. by blocking the door with your foot as the door can only be opened fully after closing it.

    Advanced versions exist where if you put strain on the chain (mostly trying to push the door open from the outside) an alarm goes off.
