In here I list software I like to use, mostly for my own benefit.
I am an Emacser. It allows me an extremely-customizable, portable environment, with quite a lot of power. Also, it's what Dr. Bui told us to use at Penn State Harrisburg on our first day of COMP 432, and it stuck.
I write plaintext files a lot. For simpler ones like readmes I tend to use Markdown these days, and for more complex ones I lean towards reStructuredText. Neither's perfect, but it beats reinventing the wheel.
For writing software, my preferred language is Python. There are no good GUI libraries for Python (or any language), as far as I can tell. I currently use wxPython for cross-platform GUI development, in conjuncture with py2exe and py2app. I use InnoSetup to create installers for py2exe packages.
pyenv lets you easily change the active Python version for a given project, and helps you install the versions your apps need: https://github.com/yyuu/pyenv
virtualenv is a Python tool for installing the modules required for a given application in their own self-contained directory. https://virtualenv.pypa.io/en/latest/
sqlmap.py is an excellent tool for showing people how deadly SQL injection actually is. Not everyone realizes that you need no technical sophistication to completely exploit a site with injection flaws, and this tool shows that admirably. http://sqlmap.org/
If I want a SQL-accessible database, for local-app/prototyping purposes, I'll tend to grab SQLite. For systems that need a Real Database, I favor PostGreSQL for being open-source, robust, powerful, and for being zealous for my data's integrity by default.
Sass's SCSS syntax makes writing CSS less painful, by giving you tools to keep things DRY. Be wary of the nesting feature, however - it tends to lead to specificity wars.
jQuery is handy for simple DOM tweaking on basic pages.
For building/maintaining lists in websites where JS is allowed, this jQuery UI plugin that modifies multiselects is decent (and I understand the codebase a little, having contributed a patch or two): https://github.com/crdeutsch/multiselect
When mail-client style autocompletion is desired in a web app, a different jQuery UI plugin can be useful: http://harvesthq.github.com/chosen/
When you want to apply pretty, customizable styles to tricky form elements (selects, file inputs, radio buttons, and the like), Uniform.js is handy. http://uniformjs.com/
If you have need of templating in PHP, Twig is the way to go, hands-down: http://www.twig-project.org/ It's strongly inspired by Jinja, which is my preferred templating language when in Python contexts: http://jinja.pocoo.org/
PHP Code Sniffer is a tool for detecting and fixing style violations in PHP source code. You can define your own style guidelines. https://github.com/squizlabs/PHP_CodeSniffer
httrack is a tool for cloning websites for offline viewing that Bob introduced me to: http://www.httrack.com/ It was more relevant before the days of the SPA came upon us.
I've decided to standardize my monospaced font, and Anonymous Pro is my current victim: http://www.ms-studio.com/FontSales/anonymouspro.html
VirtualBox is an open-source app for virtualization. It runs nicely on OS X, and is a decent (if slow) way to run MS Windows on Linux/OS X, or to play with other operating systems.
linkchecker is a simple tool for checking websites for broken links. Excellent thing to run as part of a build process, or just nightly against production, if you rely on links to other sites.
ievms is a handy script that does the painful work of making MS's IE testing VMs work on Linux/OS X. You run it, you wait N hours, and you have a working IE test setup. https://github.com/xdissent/ievms
iectrl is a program for managing the vms ievms creates. It is particularly
useful for re-installing the VMs after the Windows activation period has
expired. If you have not deleted the original downloads from ~/.ievms, you can
iectrl reinstall 8, and you'll have a working IE 8 VM in a minute or
gitlist is a no-muss, no-fuss, nice little git repo viewer. It's in PHP, so I've contributed a few patches. https://github.com/klaussilveira/gitlist
Vagrant manages development environments, treating them as a collection of 1-to-N virtual machines. It's primarily an abstraction over virtualization platforms, letting developers think in terms like 'provision my box again', 'suspend my box', 'restart my box', etc. That mindset can be especially helpful when hacking out provisioners to ensure consistency across environments. https://www.vagrantup.com/
Ansible is a solid answer to the question "How do I define an app's execution environment as a readable set of changes relative to a base OS image?" https://www.ansible.com/
https://github.com/aehlke/tag-it is a pretty usable jQuery UI plugin for tagging things. Low-muss, low-fuss. In an ideal world, this might be an enhancement of a multiselect, a la Chosen, but practically speaking, it works just fine.
http://digitalbush.com/projects/masked-input-plugin/ is a pretty usable jQuery plugin for masking HTML input fields. Not usually a good idea, IMO, but it does it about as well as I could ask for.
LogExpert is a decent Windows GUI for viewing/tailing logs: http://logexpert.codeplex.com/
Instant EyeDropper is a Windows tool for getting any on-screen color. Not flawless (only works on primary monitor), but sure beats screenshot/paste/eyedropper: http://instant-eyedropper.com/ On OS X you can just use the built in "Digital Color Meter" app.
http://typing.io/ A great little tool for exploring OSS code and learning to type code (all those little weird characters, y'know?). Basic plans are free.
eslint is an excellent style-checker and linter for JS. Plugin architecture, easily extensible, sane defaults, but everything configurable. http://eslint.org
Google Chrome is my preferred browser (for web development and general browsing). It has some awesome built-in features, many of which can be discovered by loading its list of internal URLS in a Chrome tab: chrome://chrome-urls/
If you frequently use a URL with variable data somewhere in it, try setting it up as a custom search engine at the chrome://settings/searchEngines URL. Once you have, type your keyword, press tab, then enter the variable data. I think of these as 'templated bookmarks'.
I use a slew of extensions with Chrome:
- JSONView (make JSON responses prettier)
- Edit This Cookie (edit cookies easily)
- Swap My Cookies (store and exchange different sets of cookies)
- Vimium (browse with vim-like keys)
- Enhanced History (make history easier to use and search)
- The Great Suspender (save RAM/CPU by suspending inactive tabs)
- Stylebot (user stylesheets since Chrome dropped built-in support)
- GhostText (hook up your editor to Chrome textareas and see changes as you type)
- New tab URL (redirect new tabs to a given URL [so vimium works on new tab])
- StayFocusd (ration time on timewaster domains)
- chrome-pass for hooking Chrome up to the 'pass' CLI password manager
It's handy to open chrome-pass via keyboard shortcut, but it doesn't have one built-in. Fortunately, you can set custom keyboard shortcuts for extensions on by clicking 'Keyboard shortcuts' at the bottom of the chrome://extensions page. I use Command+Shift+L to trigger chrome-pass.
crankd (part of https://github.com/nigelkersten/pymacadmin) is a great way to kick off jobs on network connection/loss, on OS X. It'd be nice to write a wrapper around it to let me schedule jobs for "when I have a connection again", like scheduling git pushes for when I have a connection.
iconv is a venerable tool for converting bytestreams from one character encoding to another. It is thus useful for diagnosing character encoding errors. If you feed it a document to convert from its claimed encoding to another one, it will warn you if the document contains invalid byte sequences for that encoding. It can also strip such byte sequences or replace them with a placeholder of your choosing.
