The Endeavour

The Endeavour
I help people make decisions in the face of uncertainty. Sounds interesting. I’m a data scientist. Not sure what that means, but it sounds cool. I study machine learning. I’m into big data. Even though each of these descriptions makes a different impression, they’re all essentially the same thing. There are distinctions. “Decision-making under uncertainty” emphasizes that you never have complete data, and yet you need to make decisions anyway. “Data science” stresses that there is more to the process of making inferences than what falls under the traditional heading of “statistics.” Despite the hype around the term data science, it’s growing on me. Machine learning, like decision theory, emphasizes the ultimate goal of doing something with data rather than creating an accurate model of the process that generates the data. “Big data” is a big can of worms. Bayesian statistics is much older than what is now sometimes called “classical” statistics. Related:  Wiki, Blog, Tuto

Mathieu Agopian Le problème Hier, le 8 avril 2014, une énorme faille de sécurité a été divulguée, nom de code Heartbleed (plus d'infos sur Elle impacte OpenSSL, qui est la technologie qui permet de sécuriser les échanges entre notre navigateur et les sites qui utilisent des adresses qui commencent par " (notez bien le "s" final). On estime qu'elle impacte environ 2/3 des sites sur internet. Ces sites qui utilisent SSL apparaissent avec un petit cadenas à gauche de leur adresse, dans la barre d'adresse de votre navigateur, indiquant que la connexion est sécurisée. Cette sécurité permet de chiffrer toutes les communications entre le navigateur et le site, empêchant quiconque de pouvoir espionner (par exemple en "sniffant" le wifi sur lequel vous êtes connectés) et récupérer vos mots de passe. Petite note pour les utilisateurs de Google Chrome : je vous recommande d'utiliser Firefox. Ce qu'il faut faire

Apolitically Incorrect Newsweek has a fascinating article about an archaeological site at Göbekli Tepe in Turkey that is well worth a look. The site is the oldest religious temple ever discovered. Preliminary carbon dating has determined that some of the artifacts date from 9,400 BC, which makes the place about 11,500 years old. (Which, just to be clear, is 7000 years before the Great Pyramid and 6500 years before Stonehenge.) The article further explains: The ruins are so early that they predate villages, pottery, domesticated animals and even agriculture – the first embers of civilization. … [It] may be the very first thing that human beings ever built. And yet, the site is amazing. This quote from Ian Hodder, head of archaeology at Stanford University, summarizes my response pretty well: [Göbekli Tepe] is unbelievably big and amazing, at a ridiculously early date. This doesn’t happen often. Göbekli is literally an outlier in every way. To really put this in perspective, consider the timeline below.

DevTricks Ferdy Christant A few months ago I took one of the best decisions for JungleDragon in a long while: to open up parts of its operations to the community, by means of moderations tools. It has been working very well, the community is happy with it, and it eliminates the reliance on a single person. One of such moderations tool is the ability to promote a photo to the homepage. I just changed that. There are two main benefits to this approach: It gives moderators far more power, being able to promote any of the 14,000+ photos, instead of a handful of recent ones. I am rarely fully satisfied with what I develop for JungleDragon, always thinking I can do better. We're having another wildlife photo contest at JungleDragon for the month of April, yet already starting today. I just deployed a redesigned homepage for JungleDragon. The "old" homepage First, a glance at how the homepage was: The old homepage was quite compact. The new homepage Without further delay, here's the new homepage design: Say what? Doing good

Le blog de Rémi Thompson's Technological Insight Walking Randomly William Edwards, Coder Monday, April 7, 2014 I’m giving a Mill CPU talk in Växjö, Sweden 2014-04-25 There are perhaps a few seats available to interested members of the public if you’re in or near Växjö at the end of the month :) Announcing a presentation at 13.00h, Friday, April 25 at: Linnéuniversitetet (Linnaeus University) Vejdes Plats 6, Linnéuniversitetet Building B, Room 3021 352 52 Växjö Sweden The new Mill CPU architecture A presentation by Will Edwards (Mill Computing) The new Mill CPU architecture brings DSP-like efficiency and performance to general purpose computing. The Mill is an extremely wide-issue VLIW design, able to issue up to 33 operations per cycle. This talk will give a high-level introduction to the Mill programming model, with an opportunity for the audience to ask more detailed questions in areas of interest.

Eli Bendersky's website Learning Python, Linux, Java, Ruby and more with Videos, Tutorials and Screencasts The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!) by Joel Spolsky Wednesday, October 08, 2003 Ever wonder about that mysterious Content-Type tag? You know, the one you're supposed to put in HTML and you never quite know what it should be? Did you ever get an email from your friends in Bulgaria with the subject line "???? I've been dismayed to discover just how many software developers aren't really completely up to speed on the mysterious world of character sets, encodings, Unicode, all that stuff. But it won't. So I have an announcement to make: if you are a programmer working in 2003 and you don't know the basics of characters, character sets, encodings, and Unicode, and I catch you, I'm going to punish you by making you peel onions for 6 months in a submarine. And one more thing: In this article I'll fill you in on exactly what every working programmer should know. A Historical Perspective The easiest way to understand this stuff is to go chronologically. And all was good, assuming you were an English speaker. Unicode Hello Encodings Right?
