Benchmarking correctly is hard. Criterion generates HTML reports: http://t.co/J15W2yTr2q and performs linear regression to measure noise!

Found my first genuine bug using quickcheck! It can be hard to write properties, but http://t.co/fpkY7zIoWA is very helpful.

Nifty Emacs command of the day: helm-imenu. It lets you jump to definitions within a file, but also gives you an overview of that file.

ENSIME is a very nice Scala package for Emacs: http://t.co/9BxwSWjFl5 -- why don't more languages offer an 'inspect type' feature?

Writing an autocomplete tool for IDEs is an interesting problem. Rust is using AST pruning, C# uses lazy compilation http://t.co/zabM0tsthH

I'm having fun with quickcheck, but it definitely takes careful thought. You need tests that can be parameterised over a range of inputs.

I really like that Rust's build tool compiles all the files in your examples/ directory by default. It means examples actually work!

Today's useful, less known Emacs command: helm-all-mark-rings. It lets you jump to anywhere on the mark ring in any buffer!

There are serious proposals for removing trigraphs in the next C++ version: http://t.co/N8fSpnjH8v Nice to see some simplification.

Woah, dash.el has really nice pattern matching! (-let [(_ _ _ in-string in-comment &rest _) (syntax-ppss)] (or in-string in-comment))

"Stories take an average of 8 seconds to load, by far the slowest single content type on Facebook." http://t.co/XdvR87MPo2 (web is bonkers!)

CSS browser prefixes have become a compatibility issue: https://groups.google.com/forum/m/#!topic/mozilla.compatibility/ekZBqfOnzTc/discussion (interesting Facebook sends browser-specific CSS for perf!)

GCC 5: Faster binaries, better warning, nicer output, more standards support. Fantastic, but too much to fit in a tweet!

GCC 5 defaults to C11 (from C89)! Fixes a paper cut for new C developers.

OH at the last Emacs meetup: "What shell do you use? Zsh, bash, ...?" "I use Korn 93!" — I've never met two elispers with the same workflow.
