How? Shouldn't it just all be UTF-8? Or do you use a different encoding on your system?

I propose infinite timezones, you simply calculate the true noon from your latitude. Smartphones can do that for us. The time at your workplace would be some minutes off the time at your home. And when your phone is off, you are screwed. It

Name resolution problems are the most bizarre. And they happen at every level and can combine beautifully. I had a DNS server flooded with Format Error messages, because NTP Pool DNS sent an invalid response for a specific query and two (ye

When you say it like that, nothing really is serverless. Everything is running on some computer. Serverless architectures are provided by servers.

IPv6 link-local addresses based on MAC address are neat, I use that in production. We build a machine containing six cameras. All of them come with the same default IPv4 address, but the MAC address is based on the serial number, so the IPv

What I don't get is, why are we still adding more undefined behaviour to the standard? For example, C++23 got std::unreachable. From my dips into Rust, I expected something similar to std::abort, terminating the program in some sane an

You can declare and inline-define a function in a CPP file and you don't need inline because there are no other places that can import it. It's only needed for functions defined in header files where multiple definitions may exist

But if I can't trust even that host, I also can't trust the host I'm working on and which doesn't need agent forwarding to access my SSH agent.

The point of images in texts isn't to target illiterate users, either. A tutorial for a graphical user interface would surely benefit from some screenshots of that very graphical user interface thrown in there. The tutorial literally e

I recently build some internal app with Qt. Unfortunately, building Qt apps on Windows is somewhat complex. Also I didn't find a way to install Qt on Windows without later receiving E-Mails from Trolltech (or The Qt Company, nowadays)

I even know of vending machines that have routers with OpenWRT and dnsmasq in them. Mainly because I put those there.

I shifted to using systemd-boot as default years ago and don't look back. Granted, prior to Debian Bookworm I had to roll my own initramfs- and kernel-hooks, but there were blog posts and I didn't need to develop them. I even trie

Which is kind of the point. BTRFS only has issues with RAID5/6 configurations. Using it as a filesystem for a single disk or partition should be totally fine.

At some point, I felt like I knew them all. There are probably more regex dialects out there, but I don't encounter them and my set of knowledge works most of the time. I feel it's like driving a rental car. It behaves slightly di

The differences of the various regex "dialects" came to me over the years of using regular expressions for all kinds of stuff. Matching EOL feels natural for every line-based process. What I find way more annoying is escaping char

Also, a lot of devices require very specific ioctl() commands to work with and don't provide everything as a file. For example, you can't set the baudrate of a serial port by writing it to some /proc node.

People don't get the security concepts. Probably, just a lot of people wanted signed commits because they somehow "better", but couldn't get PGP to work. But they use SSH keys to push to GitHub anyway, so someone added t

Well, otherwise `if grep "line" $file; then` wouldn't work, which in my opinion is the primary use case for grep in scripts. I'd still prefer a `grep <args> || true` over not having `set -e` for the whole file.

by wolletd 3y ago
Just adding `set -e` also exits the script when a subshell exits with non-zero error code. I'm not sure why I would leave `set -e` out in any shell script.

In my case, the application was using the Wireguard MTU correctly, but the Wireguard packet itself was too big for something on the path. So, the Wireguard MTU wasn't set correctly, basically. But Wireguard packets aren't marked D

Just to be fair: as also stated at the beginning of the post, CPUs are far more complex nowadays than they represent themselves to the outside. They don't work like a von-Neumann machine, they act like one. Granted, we know a lot more

Absolutely, yes, should've mentioned that. Most of these tools are for internal use at my company and I know what terminals they run in – even better: I can just test it. But honestly, some of these run in tmux on my machine and in the
