curl with partial files Back in September 2023, we extended the curl command line tool with a new fairly advanced and flexible variable system. Using this, users can use files, environment variables and more in a powerful... daniel.haxx.se · daniel.haxx.se [1] This is a cool new feature coming to bash, I can’t think of a use case I have out of the gate, but it looks cool. I’m thinking this might be good to keep in the back pocket for something like CI where I don’t have a hightly tuned bashrc file, and I want a dynamic curl request based on some state that exists as a fille.

- Red Hat has donated the whole open alternative to docker to the CNCF, the hosts weigh in with thier opinions all being pretty positive as they seem to be a legitimate donation and not dumping crap on open source. - podman - podman-desktop - buildah - compose-fs - podman - bootc - scopio Personally I’ve been running podman exclusively at home since switching to Bazzite in August. I’d like to use buildah in ci. I gave it a try, but was unable to swap out my use of kaniko for buildah, I will get there, but it was not quite as drop in as I wanted.

- Damn Glorious Eggrolls is still making gaming on linux better. Of course its containerization that drives everything on linux these days. This is a pretty badass talk. Umu is already running in steam and bazzite. Bazzite gamemode uses this to get a gamescope session running.

Dedicated Servers | Intel Servers | AMD Servers - Dedicated Hosting reliablesite.net [1] Dax talked about this in a recent How about tomorrow podcast https://thoughts.waylonwalker.com/post/461. He is using it as his dev machine, he just ssh’s in and devs on it. Feels like quite an interesting workflow, their prices seem competitive, but as a cheap ass homelabber I see their prices and think I could grab a used optiplex for the cost of a month or two of these and probably wouldn’t know the difference. DAX mentions longer compile times so maybe he does notice. References: [1]: https://www.reliablesite.net/dedicated-servers/

- This is a pretty great episode talking shop with typecraft. They talk setups, cameras, content creation. I found them talking about their linux setups particularly interesting. Dax talked about his flow from building his own machines to using reliablesite.com. tmux default leader # [1] Dax hates on c-a, both typecraft and dax use c-s, which normally freezes a terminal, we can all agree that is useless. I use the default c-b, it seems fine for me. type crafts setup # [2] - Ubuntu - Ghosty - Tmux - Nvim - Ruby Selling coffee without a web front end # [3] Dax talks about terminal.shop and how they originally planned to have a web front end, but after they had so much success they stuck with it. now they are leaning harder into it and are building out integrations with a bunch of languages and an api, but no front end.

Using OPNsense with Tailscale · Tailscale Docs Set up a Tailscale VPN on OPNsense. Get secure communication across your devices without the need for complex configuration. Tailscale · tailscale.com [1] On reboot of my opnsense router it did not tailscale up. I’m not sure if a key expired or what happened. The fix was to first enable ssh, then ssh in and run tailscale up. enable ssh # [2] In opnsense System > Settings > Administration > Secure Shell > Enable Secure Shell tailscale up # [3] ssh <opnsense ip> 8 # to select shell tailscale up Follow the link to log in. disable ssh # [4] now uncheck secure shell to lock down the opnsense machine.

Taildrop · Tailscale Docs Send files between your personal devices on a Tailscale network. Tailscale · tailscale.com [1] Tailscale comes with a feature called taildrop that lets you easily share files between machines on your tailnet. If you have tailscale on ios/android it shows up as a share target when you try to share something, and you can pick the machine to share with. What was not obvious to me was how to receive the file on linux. The linux tailscale service does not automatically receive the file, which can be kinda nice that you can put it where you want, but was not obvious to me at first. Use this command to receive files. sudo tailscale file get . References: [1]: https://tailscale.com/kb/1106/taildrop?tab=linux

Inside 22,734 Steam games About a year ago I blogged about games that use curl. In that post I listed a bunch of well-known titles I knew use curl and there was a list of 136 additional games giving credit to curl. Kind of ... daniel.haxx.se · daniel.haxx.se [1] Interesting to see that curl is used in so many places. I often think of things like games being so windows centric and curl being so linux centric I don’t even think of these things crossing paths as much as they do.

wcurl is here Users tell us that remembering what curl options to use when they just want to download the contents of a URL is hard. This is one often repeated reason why some users reach for wget instead of cur... daniel.haxx.se · daniel.haxx.se [1] interesting, seems like such a simple way to completely remove the need of a whole other cli. No offense to anyone working on wget, but generally I use it out of lazyness or something wierd is happening and I am looking for a second opinion. Cool to know that wcurl exists and will start shipping with curl. References: [1]: https://daniel.haxx.se/blog/2024/07/03/wcurl-is-here/
