Rust kernel development needs a far different setup than most projects — so by passing these flags to rustup-init, you can ensure that you’ll have a Rust toolchain that will work on your system with little, if any, effort.

Old cron doesn't allow periods
Use libcaca to render ascii chars on the webcam input... or don't.
Although the need to type a password to make certain changes to the system may make perfect sense in a business or educational environment, it makes absolutely zero sense to the home user. So, if you’re at home and would rather get work done than be annoyed by what is essentially Linux’s UAC, then this command is for you.

This version won't reconnect if you exit the ssh connection with a non-zero exit code. ConnectTimeout and sleep values knobs for how long to wait for each retry.
Kernel developers might need to know what indices to map to the IOAPIC if building a new kernel from scratch. This command gives users a guide to go off of.

This is a standard procedure for me, whenever I set up a new Raspberry Pi system. Because the default user is "pi", I quickly replace it with my own (e.g. "kostis"), but I have to substitute that user to all of pi's groups first, before deleting the default account. xargs helps a lot with that in a single line, while avoiding boring "for" loops. For everything trickier, there's always "parallel" :)
Alternatively, the kernel provides a script to cleanly compare two config files even if the options have moved in the file itself: /usr/src/linux/scripts/diffconfig .config.old .config
Because Mac app bundles contain everything in one place, it makes running them from anywhere, including from a device such as a USB flash drive or external HDD, possible. So if your Mac has a mere 256GB of storage (as mine does), you can free up large quantities of disk space by storing apps like, say, Xcode on external devices.
commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.
Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.
