Dave Johnson on open web technologies, social software and Java
Interesting speculation on the make-up of Amazon's cloud:
We know that Linux on servers is big and getting bigger. We also knew that Linux, thanks to open-source cloud programs like Eucalyptus and OpenStack, was growing fast on clouds. What he hadnt know that Amazons Elastic Compute Cloud (EC2), had close to half-a-million servers already running on a Red Hat Linux variant.
Huang Liu, a Research Manager with Accenture Technology Lab with a Ph.D. in Electrical Engineering whose has done extensive work on cloud-computing, analyzed EC2s infrastructure and found that Amazon EC2 is currently made up of 454,400 servers.
JIRA's got a real REST API now:
REST easy with JIRA 5 | Atlassian Blogs: Now that JIRA 5 is out, lets talk about one of my favorite features of this new release, JIRAs new REST API. JIRA has supported remote APIs for many years with SOAP, XML-RPC, and JSON-RPC. However, telling developers that you support SOAP (and only SOAP) is like saying that you like writing applications with COBOL its out of style. Todays cool kids gravitate towards REST. Its clean, simple, and highly portable across languages and frameworks.
An alternative to Atlassian's new API is the recently release Rational OSLC Adapter for JIRA, which allows you to do more sophisticated integrations with JIRA including delegated UIs for issue creation and selection.
This is the fifth in my series of Web Integration Patterns. Check out the intro at this URL http://rollerweblogger.org/roller/entry/web_integration_patterns
Allow other web sites and applications to integrate your site into their web pages by providing an embeddable user interface, commonly known as a Gadget or Widget, which allows users to view and interact with your site in the context of other sites.
This is such good news for the web that it gets its own blog entry. According to Dan Web, an engineer at Twitter:
@timhaines plus, now I'm in charge of undoing twitters hashbang URLs I can
confirm that all the issues in that article are very real.
@danwrong x months from now (when your project completes) Twitter will no
longer use hashbangs?
@timhaines correct. All gone. It was a mistake for several reasons.
PushState or bust.
The whole conversation is here:
Here's an excellent chapter on HTML 5 history and PushState: http://diveintohtml5.info/history.html
And in case you've forgotten, here's why hashbangs suck.
Worth a read and related to my Web Integration Patterns post on Embedded Properties in HTML:
HTML5 Microdata and Schema.org:HTML5 Microdata and Schema.org On June 2, 2011, Bing, Google, and Yahoo! announced the joint effort Schema.org. When the big search engines talk, Web site authors listen. This article is an introduction to Microdata and Schema.org. The first section describes what HTML5, Microdata and Schema.org are, and the problems they have been designed to solve. With this foundation in place section 2 provides a practical tutorial of how to use Microdata and Schema.org using a real life example from the cultural heritage sector. Along the way some tools for implementers will also be introduced. Issues with applying these technologies to cultural heritage materials will crop up along with opportunities to improve the situation.

A reasonable check-list for selecting an open source project:
How I select Open Source projects: An Open Source project is more than its set of tools. But this post is not about what is better, github or ASF. Much has been said already about it (and too much bullshit). What really bugs me is that people seem to choose Open Source projects after the tools the projects use. Here is my personal list after which I choose projects.

Apparently 2001 called and asked for its office suite back.
IBM to close down Symphony, its OpenOffice fork | ZDNet : This move cant come as too much of a surprise. In July 2011, IBM started donating its Symphony code to the Apache Foundation, which is now overseeing the remains of the OpenOffice project. I say remains because most of the development energy in the OpenOffice family has been going to the LibreOffice fork. Many users and Linux distributors, such as Ubuntu, have replaced OpenOffice with LibreOffice.
Nice coverage of Wayin in CNN Money:
Scott McNealy's Wayin weighs in on the election - Fortune Tech: Nearly 30 years after he co-founded Sun, and two years after the company sold to Oracle (ORCL), one of the tech industry's most outspoken and colorful executives is back. Only instead of selling servers and software to businesses, he's trying to get consumers, sports teams, and corporations -- and politicians -- to embrace a social media tool that's a little hard to define: It is part polling app, part interactive media tool (think Twitter), and part enterprise service.
The polling software at the heart of Wayin is super easy to use. It allows you to create basic questionnaires, on the web or using a mobile app, by selecting an image and asking a question. Pick a photo of the Fab Four, ask Who is your favorite Beatle?, and bingo, the answers from your followers will start trickling in immediately.
Good information on a bad API. The comments are good too:
HttpURLConnection's Dark Secrets: If youre programming in the Java language and want to talk to a Web server, there are several libraries you can choose from. HttpURLConnection is one popular choice, and for Android programming, the engineering team has now officially suggested that you use it where possible.
Great analysis, as usual, from Stephen O'Grady of Redmonk. Here's the part about Dynamo that concerns me, the lock-in:
Amazon DynamoDB: First Look: Like the initial wave of PaaS platforms, however, DynamoDB is available only through a single provider. Unlike Amazons RDS, which is essentially compatible with MySQL, DynamoDB users will be unable to migrate off of the service seamlessly. The featureset can be replicated using externally available code via those projects that were originally inspired by DynamoDB, for example but you cannot at this time download, install and run DynamoDB locally.
Worth a read:
Werner Vogels: Amazon DynamoDB is a fully managed NoSQL database service that provides fast performance at any scale. Todays web-based applications often encounter database scaling challenges when faced with growth in users, traffic, and data. With Amazon DynamoDB, developers scaling cloud-based applications can start small with just the capacity they need and then increase the request capacity of a given table as their app grows in popularity. Their tables can also grow without limits as their users store increasing amounts of data. Behind the scenes, Amazon DynamoDB automatically spreads the data and traffic for a table over a sufficient number of servers to meet the request capacity specified by the customer. Amazon DynamoDB offers low, predictable latencies at any scale.

The Rise of the New Groupthink - NYTimes.com: Solitude has long been associated with creativity and transcendence. Without great solitude, no serious work is possible, Picasso said. A central narrative of many religions is the seeker Moses, Jesus, Buddha who goes off by himself and brings profound insights back to the community.

I feel pretty strongly about this. I won't vote for a politician who backs SOPA or PIPA:
Obama Administration Comes Out Against SOPA, PIPA | TPM Idea Lab:Even more promising for critics of the bills, the Administration came down firmly against one of the most vehemently opposed portions of the bills the part that would give the government the power to force Internet Service Providers to stop loading overseas webpages accused of piracy. Under the original versions of SOPA and PIPA, ISPs would be required to change their Doman Name System settings to block sites accused of piracy, a measure that critics said would essentially break the Internet and make it more insecure.

New York City gets a Software Engineering High School - Joel on Software:This fall New York City will open The Academy for Software Engineering, the citys first public high school that will actually train kids to develop software. The project has been a long time dream of Mike Zamansky, the highly-regarded CS teacher at New Yorks elite Stuyvesant public high school. It was jump started when Fred Wilson, a VC at Union Square Ventures, promised to get the tech community to help with knowledge, advice, and money.
Survey says 80% of New Relic's Java customers choose open source app servers over expensive bloat-ware.
Server wars: Open-source Java vs Weblogic and WebSphere | Software, Interrupted - CNET News: Overall, it's not surprising that users who are deploying their applications to the cloud are more likely to use open source, if for no other reason than that licensing is far simpler. Additionally, there are Amazon Machine Images (AMIs) available for most open source stacks, making it very easy to choose open source over a traditionally licensed application server.
jVi Home Page: NetBeans 7.1 Bug 205835 can lose edits; a variety of jVi commands run into this. jVi-1.4.5 disables itself if it detects module versions with the bug, AFAICT. The bug is scheduled to be fixed in NB-7.1.1; sometime around January/February.
Seriously, how can you ship without vi?
I hate the "will die" title but Antonio Rodriguz insightfully sums up the state of Android and it does not sound strong, to say the least. All the more reason to take a hybrid approach, e.g. project formerly known as PhoneGap.
Android as we know it will die in the next two years and what it means for you: I used to think that, as with Linux and web services in the early part of last decade, Android was going to be the mortar for the Internet of post PC devices an essential ingredient to put stuff together. And as bonus, unlike Linux which puttered away quietly in the background doing the heavy lifting for services like Amazon and Google, Android was largely user-facing and would also therefore benefit from massive platform scale (and the resulting de-facto standard it would create) the way no piece of software since Microsoft Windows had.
