plainas/tq
command line utility that performs an HTML element selection on HTML content passed to the stdin. Using css selectors that everybody knows. Since input comes from stdin and output is sent to stdout, it can easily be used inside traditional UNIX pipelines to extract content from webpages and html files. tq provides extra formating options such as json-encoding or newlines squashing, so it can play nicely with everyones favourite command line tooling.

tinystat - GoDoc
tinystat is used to compare two or more sets of measurements (e.g., runs of a multiple runs of benchmarks of two possible implementations) and determine if they are statistically different, using Student's t-test. It's inspired largely by FreeBSD's ministat (written by Poul-Henning Kamp).

awscli

The future of the AWS command line tools is awscli, a single, unified, consistent command line tool that works with almost all of the AWS services. Here is a quick list of the services that awscli currently supports: Auto Scaling, CloudFormation, CloudSearch, CloudWatch, Data Pipeline, Direct Connect, DynamoDB, EC2, ElastiCache, Elastic Beanstalk, Elastic Transcoder, ELB, EMR, Identity and Access Management, Import/Export, OpsWorks, RDS, Redshift, Route 53, S3, SES, SNS, SQS, Storage Gateway, Security Token Service, Support API, SWF, VPC. Support for the following appears to be planned: CloudFront, Glacier, SimpleDB.

The awscli software is being actively developed as an open source project on Github, with a lot of support from Amazon. You’ll note that the biggest contributors to awscli are Amazon employees with Mitch Garnaat leading. Mitch is also the author of boto, the amazing Python library for AWS.

gnuplot's dumb terminal
Turns out gnuplot has a pretty readable ASCII terminal rendering mode; combined with 'watch' it makes for a nifty graphing one-liner

The useful JVM options
a good reference, with lots of sample output. Not clear if it takes 1.6/1.7 differences into account, though

moreutils
Some really cool-looking UNIX command line utils, packaged in Debian (and therefore in Ubuntu too). A few of these I've reimplemented separately, but it's always good to replace a hack with a more widely available "official" tool. Thanks, Joey Hess!
sponge: accept input, wait til EOF, then rewrite a file;
chronic: runs a command quietly unless it fails;
combine: combine the lines in two files using boolean operations;
ifdata: get network interface info without parsing ifconfig output;
ifne: run a program if the standard input is not empty;
isutf8: check if a file or standard input is utf-8;
lckdo: execute a program with a lock held;
mispipe: pipe two commands, returning the exit status of the first;
parallel: run multiple jobs at once;
pee: tee standard input to pipes;
sponge: soak up standard input and write to a file;
ts: timestamp standard input;
vidir: edit a directory in your text editor;
vipe: insert a text editor into a pipe;
zrun: automatically uncompress arguments to command

Making Really Executable Jars
Who knew? you can make a runnable JAR file!
There has long been a hack known in some circles, but not widely known, to make jars really executable, in the chmod +x sense. The hack takes advantage of the fact that jar files are zip files, and zip files allow arbitrary cruft to be prepended to the zip file itself (this is how self-extracting zip files work).

drip
Unlike other tools intended to solve the JVM startup problem (e.g. Nailgun, Cake), Drip does not use a persistent JVM. There are many pitfalls to using a persistent JVM, which we discovered while working on the Cake build tool for Clojure. The main problem is that the state of the persistent JVM gets dirty over time, producing strange errors and requiring liberal use of cake kill whenever any error is encountered, just in case dirty state is the cause.

Instead of going down this road, Drip uses a different strategy. It keeps a fresh JVM spun up in reserve with the correct classpath and other JVM options so you can quickly connect and use it when needed, then throw it away. Drip hashes the JVM options and stores information about how to connect to the JVM in a directory with the hash value as its name.

autojump
interesting idea; extend "cd" to track which directories you cd to most frequently, then add a command to "jump" to the most-frequently used one which matches a substring you specify

Sup, OfflineIMAP and MSMTP
A good guide to installation on Jaunty. I'm trying out sup. It does a really good job of bringing the GMail experience to the commandline, so far so good; now to see if I can switch my work email over!

filemap
'File-based, rather than tuple-based processing'; based around UNIX command-line toolset; good UNIXish UI; lots of caching of intermediate results; low setup overhead -- although it does require a shared POSIX filesystem, e.g. NFS, for synchronization
