Typically, I prefer to wrap the call to free() in an if:

if (str != NULL)
free(str);

There might be some obscure malloc implementation that doesn't NOP on free(NULL). I've dealt with other people's code long enough to know making assumptions can cause trouble.

15 minutes of using Debian and I've just been reminded of how complex package management is.
Prepare for a few other ranting toots, I haven't even touched systemd yet.

On the birdsite everyone is going mad with this "by 35 you should have done X" thing and I can't help but giggle at some of the stuff I did as a child simply because I had access…

Aged 6 and a bit I crashed the main university server turning off a disk pack because, well, it was noisy and I was playing Lego in the machine room ¯\_(ツ)_/¯

The "rm -rf /" I did, on purpose, "to see what would happen" on my home Xenix SysV/386 system around 13-14…

So much other fun stuff before I even turned 18!

So the Amazon Workspaces client for Windows wants me to install an unknown, random CA to my root CA trust store.

So here's a neat bug. Apache is logging access requests to httpd-access.log with the right timestamp, but http-error.log entries are an hour off.

Because someone didn't use UTC on this server, and computers hate when you fuck with the time, and the process has been up since DST change happened.

People, use UTC. Please.

If you don't want your GPS information shared on your social network posts, DON'T COLLECT GPS INFORMATION.

You can disable Location access to the camera app in iOS. Do it. Turn it on when you actually want it, like when you're on vacation.

TIL: "No route to host" on Linux does not necessarily mean "no route to host".

If a firewall rejects a packet, it usually sends an ICMP port unreachable, which is correctly interpreted. The proper behaviour defined in RFC 1812 would be ICMP Admin Prohibited (Type 3 Code 13), but the Linux kernel converts that to EHOSTUNREACH, which is interpreted by libc as "No route to host".

Therefore - check the actual traffic using tcpdump/Wireshark. No route to host, well... doesn't mean no route to host.
