A very warm welcome to my most ambitious project to date. In this project I’m going to attempt to design and build a sprite-based graphics accelerator that will function as a co-processor to an MCU. Using cheap off-the-shelf components I’m hoping to achieve a level of gaming performance that compares well to popular…
This is my third Clojure year-in-review post. In 2011 I was excited about Clojure 1.3, ClojureScript, and the second Clojure/conj. By 2012 I was blown away by four Clojure conferences, two O’Reilly books, reducers, Datomic, Immutant, and a partridge in a pear tree.
No single cloud fits all. Explore how we build a more flexible future with hybrid cloud.
UPDATE: I’m happy to say a developer has come forward and we’re out of the woods on sound. It’s not perfect, but the web audio API isn’t perfect and we’re much better …
This notebook documents my exploration of color theory and its applications to photochemistry. It also shows off the functionality of several Julia packages: Color.jl for color theory and colorimetry, SIUnits.jl for unitful computations, and Gadfly.jl for graph plotting.
First an update on progress. You probably noticed this post took quite a while to come out. Fear not, I have not given up (yet). I have bee...
This essay discusses how to separate JavaScript domain properties from object behaviour, without prototypes . This is deliberate. By examining four basic ways to have one object define the behaviour of other objects, we gain insight into what we’re trying to accomplish at a very basic level.
Pansophical reader, with your bafflingly good mobile OCaml project, I’m ready at last to release an OCaml compiler for iOS 7. It works for all my projects, and I hope it works for yours.
It appears that Tibanne Co. Ltd. the company that operates the Mt. Gox bitcoin exchange has acquired the Gox.com domain name from Andy Booth.
Good, thorough data analysis is difficult. Throughout my work, I've found it useful to follow these principles in order to ensure quality and consistency.
In the good old days before the computer revolution, stocks were generally priced by traders using pencil and paper. Analysts would read news, study corporate financials, and then give ideas to traders. Trading happened in a physical trading pit. When a large player (Goldman Sachs, J.P. Morgan) wanted to …
I’ve done a lot of tweeting about systemd lately. My internal conscience constantly reminds me of John Allspaw saying that twitter is just pretty much perfect for snarky comments (paraphrase).
Why your API needs a vendor approved client.
Allow me to present a simple thought experiment. Suppose we didn’t need to store our code as ASCII text on disk. Could we change the way we write – and more importantly read – symbolic code? Let’s assume we have a magic code editor which can read, edit, and write anything we can imagine. Furthermore, assume we have a…
More effective than a botnet, more sweeping than a Denial-of-Service attack, ICANN has devised a deadly Weapon of Mass Destruction that can instantly render a entire online presence persona-non-grata regardless of how much redundancy, mitigation muscle-power or firewalls a hapless defender has deployed, this latest…
If you want to invest in bitcoin for the long-haul, you should address the thorny issue of how best to store them. Since people love stealing bitcoins from others more than just about anything else in this world, all storage systems must first and foremost:
I have been doing interactive programming in ClojureScript recently. After having spent some time with it, I can easily say that when I return to projects that don’t have an interactive workflow I feel like I am in the stone ages.
Posted by Garrick Toubassi, Engineering Director Editor’s note: Be forewarned that the following post has much more technical mumbo-jumbo ...
This is part 3 of a series of blog posts looking at the security of the UK Government's web infrastructure. Britain's National Health Service is riddled with old and insecure WordPress-based websites. Many of these sites have severe flaws including being vulnerable to XSS attacks. There is absolutely no suggestion…
Reader Paul Kim pointed out an entry on Michael Tsai's blog about making dispatch_once fast . While the comment in the dispatch_once source code is fascinating and informative, it doesn't quite delve into the detail that some would like to see. Since this is one of my favorite hacks, for today's article I'm going to…
