Four short links: 6 November 2009 - Barcode Scanning, Downloadable Community Book, Gov Hack Day, Android Kludges 

Date: Friday, 06 Nov 2009 17:06
Red Laser -- "impossibly accurate barcode scanning". Uses Google Product Search to identify products that you scan using the camera on the phone. I remember Rael and I talking to Jeff Bezos about this years ago, before camphones had the resolution to decode barcodes. The future is here and it's $1.99 on the App Store.

Anatomy of SSDs -- A teeth-rattlingly technical Linux Magazine article explaining the different types of SSDs (Solid State Disks--imagine a hard drive made of rapid-access Flash memory). Artur Bergman told me that installing an SSD drive in his MacBook Pro gave the greatest performance increase of any computer upgrade he'd performed since he went from no computer to one.

Four short links: 26 October 2009 - Data Exploration, Evidence-Based Coding, API to the English Language, Dual Licensing

Toiling in the Data Mines -- Tom Armitage describes the process that Berg calls "material exploration". "Programmers very rarely talk about what their work feels like to do, and that's a shame. Material explorations are something I've really only done since I've joined BERG, and both times have felt very similar - in that they were very, very different to writing production code for an understood product. They demand code to be used as a sculpting tool, rather than as an engineering material..." This and more in today's Four Short Links.

Back in February I wrote about how Linux had gone mainstream as netbooks became ubiquitous. When my Sylvania netbook died last month and the manufacturer took their sweet time responding to me I was offered a refund by the dealer. Suddenly I was surveying the market again for a good buy on a netbook preloaded with Linux. I found a wide variety of systems with Linux available from mainstream outlets and factory direct, at least here in the United States where I live. While I don't have updated market share figures it's clear, despite claims by Microsoft and their supporters, that Linux remains entrenched in the netbook market and is spreading out from there.

Four short links: 5 October 2009 - Bozo Cloud Talk, Annotation Fail(ish), Python MySQL Slash, and Infinite Books 

Date: Monday, 05 Oct 2009 16:08
Brown Cloud Marketing -- An advertorial "interviewing" the general manager of a company offering "DNS in the cloud". This might be a worthwhile service, but the way he markets it (by saying open source is "freeware" and the market leader is "legacy") reveals a rich vein of bozo. This and more in today's Four Short Links.

The Programming Language With The Happiest Users (Dolores Labs) -- Delores Labs asks, "Which languages make programmers the happiest?" In examining recent tweets related to mentions of programming languages and analyzing whether the content of the tweet expressed something positive, neutral or negative about the language, Delores Labs has concluded that users of certain programming languages are happier than others with their choice of code. You'll be surprised at the results of this interesting study. This and more in today's Four Short Links.

What The Future's All About (Webstock Words) -- Bruce Sterling, one of the founders of the Electronic Frontier Foundation and a science fiction author explains, "We're not going to get a future Cloud World as somehow opposed to a future Augmented Reality World. It can’t happen. The ideas can be clearly distinguished, but ideas about technology, labels for technology, predictions and suppositions about technology, they don't map onto actual real-world technology. Human culture doesn't work like a logical argument." This and more in today's Four Short Links.

In this webcast, Git evangelist Scott Chacon covers the basics of the Git source control system. He'll introduce the audience to Git basics: staging and committing snapshots, viewing the commit log, pushing to and pulling from servers, and creating, switching between, and merging branches. Finally, he'll quickly cover a few more advanced features - code annotation, advanced log options and possibly more, time permitting.

Four short links: 12 August 2009 - Health Data, Python Term Extraction, Network Neutrality, New Database 

Date: Wednesday, 12 Aug 2009 15:46
Improving Health Care -- Adam Bosworth has posted the text of a speech he delivered at the Aspen Health Forum. Among his points Bosworth notes "the importance of giving us all the right to our health data online." The speech starts strong and just gets better: "We should require sharing of population statistics across practices and hospitals in order to better determine what works for whom. We should reward practices and hospitals that are delivering the best most cost-effective long-term outcomes and penalize those that deliver the worst." This and more in today's Four Short Links.

The whole time the dispute between the CentOS developers was in the news development moved forward and patches were released. CentOS was never a one man show. It was perhaps in danger of forking or a name change but it never really was anywhere near point of death.

Python includes several standard programming data structures as built-in types (list, tuple, dictionary, and set). Most applications won't need any other structures, but when they do the standard library delivers.
