A port of the original iotop to C with additional features. Acts like top but for disk I/O. Good for keeping an eye on what's bogging your disk array down.
You can add a capability so that you don't need to be root to run it: sudo setcap 'cap_net_admin+eip' /path/to/iotop
Here's my command line: iotop -o -2 -6 -8
- -o - Only show processes that are currently doing I/O.
- -2 - Don't show the PRIO column, because I don't care about that.
- -6 - Don't show the SWAPIN column, because I don't care about that.
- -8 - Don't show the graph, because I want to see more of the command on the line.
In the AUR as iotop-c.
A directory of public FTP servers around the Net.
An awesome list of hosting services, plans, tiers, and other features. If you're looking for someplace for your stuff to live, you could do worse than investigating your options here.
Somebody wrote an entire Minecraft server as a bunch of shell scripts.
Requires busybox 1.35.0 or later (crashes on 1.34, for some reason), bash, gnu grep, gnu sed and nmap-ncat. Grep was actually only used once, so maybe I could make it work with the bb one?
A stackable simple-to-build single board computer storage that is open-source and modular which is made from sustainable materials. This repository contains the official production files that can be used for laser cutting and 3D printing.
A list of free public xmpp servers.
Maddy Mail Server implements all functionality required to run a e-mail server. It can send messages via SMTP (works as MTA), accept messages via SMTP (works as MX) and store messages while providing access to them via IMAP. In addition to that it implements auxiliary protocols that are mandatory to keep email reasonably secure (DKIM, SPF, DMARC, DANE, MTA-STS).
It replaces Postfix, Dovecot, OpenDKIM, OpenSPF, OpenDMARC and more with one daemon with uniform configuration and minimal maintenance cost.
Full re-implementation in Go.
An inexpensive server and web hosting company. Virtual machines, dedicated servers, and colo services. Very inexpensive. Might be useful in a pinch to spin something up. Fully managed. Conventional and SSD storage. Multiple data centers around the world. Shared hosting plans have free daily backups. Multiple VPS tiers. Pay monthly or yearly to get a discount.
Wants to be the "cryptographic right answers" document, but for SSH.
Archived.
Maybe have Glitch monitor it?

This guide arose out of the need for system administrators to have an updated, solid, well researched and thought-through guide for configuring SSL, PGP, SSH and other cryptographic tools in the post-Snowden age. Triggered by the NSA leaks in the summer of 2013, many system administrators and IT security officers saw the need to strengthen their encryption settings. This guide is specifically written for these system administrators.
The focus of this guide is merely to give current best practices for configuring complex cipher suites and related parameters in a copy & paste-able manner. The guide tries to stay as concise as is possible for such a complex topic as cryptography. Naturally, it can not be complete. There are many excellent guides (II & SYM, 2012) and best practice documents available when it comes to cryptography. However none of them focuses specifically on what an average system administrator needs for hardening his or her systems' crypto settings.
