In my attempt to push puppet to its limits , (for no particular reason ), to develop more powerful puppet modules , to build in a distributed lock manager , and to be more dynamic , I’m now attempting to build a Finite State Machine (FSM) in puppet.
Two days ago the official hard-float Oracle Java 7 JDK has been announced on the official Raspberry Pi blog. Prior to this there was only the OpenJDK implementation which was lacking performance. Furterhmore the Raspberry Pi Foundation announced that future Raspbian images would ship with. Oracle Java by default. If you want to give it a spin you can install the JDK with: $ sudo apt-get update && sudo apt-get install oracle-java7-jdk

An excerpt from the Popular Science article in which they laid out their reasoning behind turning comments off. As John Gruber said , it’s hard to believe it took them this long. “A politically motivated, decades-long war on expertise has eroded the popular consensus on a wide variety of scientifically validated topics. Everything, from evolution to the origins of climate change, is mistakenly up for grabs again. Scientific certainty i....
I just realized that my Fedora 19 installation didn’t have any of the GNOME games installed by default any more. I guess there’s no love for nibbles .

I always find it interesting when I realize that something I have been practicing or dealing with for a long time has a name. This time it happens to be race conditions. This is something you can’t avoid thinking about as soon as you have more than one routine sharing any kind of resource. If you’re not thinking about race conditions in your code, now is the time. A race condition is when two or more routines have access to the same re....
This article was written for and published by Gopher Academy I was looking at a code sample that showed a recursive function in Go and the writer was very quick to state how Go does not optimize for recursion, even if tail calls are explicit. I had no idea what a tail call was and I really wanted to understand what he meant by Go was not optimized for recursion. I didn't know recursion could be optimized. For those who don't k....

How to make your code more concise and well-behaved at the same time Have you ever had an application that just behaved plain weird? You know, you click a button and nothing happens. Or the screen all the sudden turns blank. Or the application get into a “strange state” and you have to restart it for things to start working again. If you’ve experienced this, you have probably been the victim of a particular form of defensive programming whi..

Overcast - overcast.fm - 12 years ago - eng
I absolutely love podcasts. Much to my girlfriend’s confusion, I might add. After Marco Arment sold Instapaper in April, after Yahoo! bought Tumblr. 1 in May, and after he sold The Magazine shortly thereafter, only in my wildest dreams did I hope his elusive next venture would lead Marco to create a podcast client. Then, last Sunday at XOXO, my dream came true. Perhaps that’s putting it slightly melodramatically, but to say that I — an....
Another great article by Ben Thompson, this time on Clay Christensen’s interesting disruption theories and Apple’s approach in making products that both defy them and motivate people to purchase en masse. Come for the insights into Apple, and stay for his dissection of Christensen’s widely-regarded theory; this article is well worth the read. Permalink.
I realize in my last two articles, Instapaper 5  — in which I made a number of proposals for Instapaper 5 — and Betaworks Releases Instapaper 5  — in which I conveyed my mostly positive feelings on the new release — I likely appeared very critical of Betaworks and their continued work on Instapaper. This is not the case: while I do feel a better launch strategy entailing a service-wide design overhaul and one in which they added a lar....
Looking again at that chart, and with the realities of these three markets in mind, it’s not so much that the iPhone has saturated the American-style and European-style markets, and ought to focus on the Asian-style one; rather, the iPhone has saturated the high end in all three markets the high end just varies in accessibility ($200 for American-style, $650 for Asian-style). And, if you accept that the iPhone is in roughly the same compet....
By now I realize this issue has largely fallen to the wayside, as its various permutations invariably do seemingly momentarily after gaining any significant traction, despite the condemnation many so readily metered out. Regardless of its fall from the collective’s fickle favor though, the event and ensuing discussions nevertheless merit some examination. Permalink.
De-Anonymizing Alt.Anonymous.Messages TOM RITTER In recent years, new encryption programs like Tor, RedPhone, TextSecure, Cryptocat, and others have taken the spotlight - but the old guard of remailers and shared inboxes are still around.

For the truly paranoid, there is no communication system that has better anonymity ....
