  • They’re just examples of things you could pipe curl into, but no not really. If the download fails you end up with an incomplete file in your tmpfs anyway, and have to retry. Another use I have is curl | mysql to restore a database backup.

    If the server supports resuming, I guess that can be better than the pipe, but that still needs temporary disk space, and downloads rarely fail. You can’t corrupt downloads over HTTPS either as the encryption layer would notice it and kill the connection, so it’s safe to assume if it downloaded in full, it’s correct.

    With downloads being IO bound these days, it’s nice to not have to read it all back and write the extracted files to disk afterwards. Only writes the final files once.

    That’s far from the weirdest thing I’ve done with pipes though, I’ve installed Windows 11 on a friend’s PC across the ocean with a curl | zstd | pv | dd, and it worked. We tried like 5 different USBs and different ISOs and I gave up, I just installed it in a VM and shipped the image.


  • I’ve had to use that flag.

    --silent is useful when you don’t want the progress bar or you’re piping curl into something else. I like to do curl | tar -zxv to download and decompress at the same time, I’ve even tar -zc | curl to upload a backup taking no disk space to do so.

    The problem however is it’s really silent: if it fails, it exits with a non-zero code and that’s it. Great when you don’t want debug info to interfere, annoying when you need to debug it.

    So you can opt-in to print some errors when in silent mode, but otherwise be silent.







  • Arguably, if it was normal to sideload apps it wouldn’t be as much of a barrier to users, but they’ve been conditionned to think they need an app and the only place you can ever get them is the store.

    It’s a technical hurdle only because Apple decided they want to control everything, and same on Android because of Google’s ever increasing war on sideloading. You used to download an APK from the browser and it would go like “This is an app! Install?”, but now you have to go enable third party installation and all that, and now the whole Play Protect forcing developer validation coming up.





  • No way. iPhones don’t exactly allow bootloader unlocking to begin with, but even if you could, it would be in no better state than Asahi on the M1 Apple computers. Every driver would have to be written from scratch.

    Pixels are a good platform for custom ROMs because until the recent drama, you could literally just build AOSP as-is and use it. So the GrapheneOS team only really need to focus on their changes to the OS and their apps and none of the drivers and modem interface and all that. That’s also why GrapheneOS runs so well on it: Google provided everything, it just works.

    iPhones would be the absolute worst phone to develop for: zero support from Apple, no drivers no documentation, no nothing. Not even a Linux kernel! At least for Android, the Linux license forces manufacturers to publish the source code, so at minimum you start with something that should boot and contain all the stuff to talk to the hardware already, just need to wire it in with userspace drivers. CPU manufacturers like Qualcomm also provide a fair chunk of the userspace drivers open-source too, so you can just pull that and have audio and video working.

    Not impossible, but definitely really hard and impractical.



  • It’ll tolerate a few hours no problem, mine’s been down for a bit over 24h and caught up fine.

    I think it marks instances as down after 2-3 days, but I’m not sure if it’ll resume once it comes back up at this point. I think if your instance reaches out it might start pushing events again but it could also result in dropping the previous days.

    Free speech includes respecting speech you disagree with and speech that makes you uncomfortable.

    If the roles were reversed and you were lined up to be banned because you’re not siding with the “correct” side, you’d be crying abusive censorship.

    That’s what the downvote and block buttons are for.




  • For all its flaws and mess, NFS is still pretty good and used in production.

    I still use NFS to file share to my VMs because it still significantly outperforms virtiofs, and obviously network is a local bridge so latency is non-existent.

    The thing with rsync is that it’s designed to quickly compute the least amount of data transfer to sync over a remote (possibly high latency) link. So when it comes to backups, it’s literally designed to do that easily.

    The only cool new alternative I can think of is, use btrfs or ZFS and btrfs/zfs send | ssh backup btrfs/zfs recv which is the most efficient and reliable way to backup, because the filesystem is aware of exactly what changed and can send exactly that set of changes. And obviously all special attributes are carried over, hardlinks, ACLs, SELinux contexts, etc.

    The problem with backups over any kind of network share is that if you’re gonna use rsync anyway, the latency will be horrible and take forever.

    Of course you can also mix multiple things: rsync laptop to server periodically, then mount the server’s backup directory locally so you can easily browse and access older stuff.
