Extracting Colors With Colorific

At 99designs we love great design, and a big part of good design is use of color. We were interested to see how designers make use of color in their designs, so we built an automatic color extractor to enable us to analyse color usage at a massive scale. Think of a design you love.

Developer Mailing List, a paraphrase from Liar's Poker

On braver days you cruised the mailing list to find a senior developer who would take you under his wing, a mentor, better known to us as a rabbi. You also went to the mailing list to learn. Your first impulse was to step into the fray, select a likely teacher, and present yourself for instruction.

E2E: Donna Malayeri, Gilad Bracha, Luke Hoban - Web Programming and More

At Lang.NEXT 2012, several conversations happened in the "social room", which was right next to the room where sessions took place. Our dear friend, Erik Meijer, led many interesting conversations, some of which we are fortunate enough to have caught on camera for C9.

A large-scale in-memory storage example – social network data

This posting is a follow-up to the large-scale low-latency (RAM-based) storage related price estimates in my previous posting Main takeaways from Accel’s Big Data Conference. Assume you were to store and index large amounts of social network updates in-memory, e.g. tweets.

flexible, scalable, relational data mining language

Back in March the friendly and helpful Pangool developers posted some interesting benchmark results for Hadoop-based tools. There's lots of talk elsewhere about Hadoop scalability but we hear very little about performance so I was excited to learn more about relative performance of these tools.

Software Engineers All!

Scott Thompson was let go this week as CEO of Yahoo for falsely claiming to have earned a bachelor's degree in computer science. I need not rehash the events, which played out in the headlines for the last ten days, nor need I enter into the ethics of the matter.

Memory Reordering Caught in the Act

When writing lock-free code in C or C++, one must often take special care to enforce correct memory ordering. Otherwise, surprising things can happen. Intel lists several such surprises in Volume 3, Section 8.2.3 of their x86/64 Architecture Specification. Here’s one of the simplest examples.

please don’t learn to code but give it a try

This post is a response to Jeff Attwoods post Please don’t learn to code (15th may 2012). I agree with 90% of this post, but I wanted to present a slight twist: I whole heartledly agree with Jeff when he say’s that its nonsensical that “every-one should learn to program”.

This Read-It-Later-list is just that, bookmarks of stuff I intend to read or have read. I do not necessarily agree with opinions or statements in the bookmarked articles.
