Pam-mount is a PAM module to mount volumes when a user logs in. It can mount all local file systems supported by mount, as well as LUKS volumes encrypted with the user's log-in password.

hungrycat prints the contents of a file to standard output, while simultaneously freeing the disk space it occupied. It is useful if you need to process a large file, don't have enough space to store both the input and output files, and don't need the input file afterwards. While similar in principle to running cat immediately followed by rm, hungrycat actually frees blocks as soon as they are printed instead of after the entire file has been read, which is often too late.

AIDE (Advanced Intrusion Detection Environment) is a file and directory integrity checker. It creates a database from the regular expression rules that it finds from its configuration files. Once this database is initialized it can be used to verify the integrity of the files. It has several message digest algorithms that are used to check the integrity of files. All of the usual file attributes can be checked for inconsistencies.

Resource monitor that shows usage and stats for processor, memory, disks, network and processes.

fdupes is a program for identifying duplicate files residing within specified directories.

pscircle visualizes Linux processes in the form of a radial tree.

daemontools is a collection of tools for managing UNIX services.

Atop is an ASCII full-screen performance monitor for Linux that is capable of reporting the activity of all processes (even processes have finished during the monitoring interval), daily logging of system and process activity for long-term analysis, highlighting overloaded system resources by using colors, etc. At regular intervals, it shows system-level activity related to the CPU, memory, swap, disks (including LVM) and network layers, and for every process (and thread) it shows e.g. the CPU utilization, memory growth, disk utilization, priority, username, state, and exit code.

Dstat is a versatile replacement for vmstat, iostat, netstat, and ifstat. Dstat overcomes some of their limitations and adds some extra features, more counters and flexibility. Dstat is handy for monitoring systems during performance tuning tests, benchmarks or troubleshooting.

Dstat allows you to view all of your system resources in real-time, you can, e.g., compare disk utilization in combination with interrupts from your IDE controller, or compare the network bandwidth numbers directly with the disk throughput (in the same interval).

This package provides a tiny system info utility.

Simple script to suspend or hibernate your computer. It supports hooks before and after suspending.

Sipcalc is an advanced command-line IP subnet calculator. It can take multiple forms of input (IPv4/IPv6/interface/hostname) and output a multitude of information about a given subnet.

Features include:

• IPv4

  • Retrieving of address information from interfaces.

  • Classfull and CIDR output.

  • Multiple address and netmask input and output formats (dotted quad, hex, number of bits).

  • Output of broadcast address, network class, Cisco wildcard, hosts/range, network range.

  • The ability to split a network based on a smaller netmask, now also with recursive runs on the generated subnets. (also IPv6)

• IPv6

  • Compressed and expanded input and output addresses.

  • Standard IPv6 network output.

  • v4 in v6 output.

  • Reverse DNS address generation.

Rdfind is a command line tool that finds duplicate files based on their content instead of their file names. It is useful for compressing backup directories or just finding duplicate files.

Utility to convert lsof output to a graph showing FIFO and UNIX interprocess communication.

Netcat is a featured networking utility which reads and writes data across network connections, using the TCP/IP protocol. It is designed to be a reliable "back-end" tool that can be used directly or easily driven by other programs and scripts. At the same time, it is a feature-rich network debugging and exploration tool, since it can create almost any kind of connection you would need and has several interesting built-in capabilities.

The goal is to provide a concrete library focused on verification examples, as opposed to mathematics. The library has a good number of theorems for booleans, natural numbers, and lists. It also has trees, tries, vectors, and rudimentary IO. A number of good ideas come from Agda's standard library.

The standard library aims to contain all the tools needed to write both programs and proofs easily. While we always try and write efficient code, we prioritize ease of proof over type-checking and normalization performance. If computational performance is important to you, then perhaps try agda-prelude instead.

This Emacs mode enables interactive development with Agda. It also aids the input of Unicode characters.

Agda is a dependently typed functional programming language: it has inductive families, which are similar to Haskell's GADTs, but they can be indexed by values and not just types. It also has parameterised modules, mixfix operators, Unicode characters, and an interactive Emacs interface (the type checker can assist in the development of your code). Agda is also a proof assistant: it is an interactive system for writing and checking proofs. Agda is based on intuitionistic type theory, a foundational system for constructive mathematics developed by the Swedish logician Per Martin-Löf. It has many similarities with other proof assistants based on dependent types, such as Coq, Epigram and NuPRL.

A standard library for Cubical Agda, comparable to agda-stdlib but using cubical methods.

A new Categories library for Agda

A formalised, cross-linked reference resource for mathematics done in Homotopy Type Theory. Unlike the HoTT book, the 1lab is not a “linear” resource: Concepts are presented as a directed graph, with links indicating dependencies.

Zbarlight is a simple wrapper for the zbar library. It can read all zbar supported codes.

libdmtx is software for reading and writing Data Matrix 2D barcodes of the modern ECC200 variety. libdmtx is a shared library, allowing C/C++ programs to use its capabilities without restrictions or overhead.
