Open Web

OpenStack: The 5-minute Overview What the software does: The goal of OpenStack is to allow any organization to create and offer cloud computing capabilities using open source software running on standard hardware. OpenStack Compute is software for automatically creating and managing large groups of virtual private servers. OpenStack Storage is software for creating redundant, scalable object storage using clusters of commodity servers to store terabytes or even petabytes of data. Why open matters: All of the code for OpenStack is freely available under the Apache 2.0 license. Anyone can run it, build on it, or submit changes back to the project. We strongly believe that an open development model is the only way to foster badly-needed cloud standards, remove the fear of proprietary lock-in for cloud customers, and create a large ecosystem that spans cloud providers. Who it's for: Institutions and service providers with physical hardware that they'd like to use for large-scale cloud deployments. (Additionally, companies who have specific requirements that prevent them from running in a public cloud.) How it's being used today: Organizations like Rackspace Hosting and NASA are using OpenStack technologies to manage tens of thousands of compute instances and petabytes of storage. Timeline: Openstack was announced July 19th, 2010. While many components of OpenStack have been used in production for years, we are in the very early stages of our efforts to offer these technologies broadly as open source software. Early code is now available on LaunchPad, with an inital release for OpenStack Storage expected in mid-September and an initial release for OpenStack Compute expected in mid-October.

Wow!  30GB free.  250 file formats with a "universal translation engine".  And HTML5. excerpt: "You can't have convergence unless you have the ability to translate files across different platforms and devices," Donald Leka, TransMedia's CEO, told Macworld. "There's a war between the big tech companies like Adobe, Apple, Microsoft, and Google, and these compatibility issues are not going to go away." Glide also lets you share any documents or media in your account with other users or the public. And with new desktop clients for Mac and PC that can sync a local folder up to your cloud storage space, Glide is taking on popular competitors like Dropbox, SugarSync, and Apple's own iDisk. Glide is free to use in desktop browsers and on the iPad, and free accounts get 30GB of space to start. Premium accounts offer 250GB of space for $50 per year.

Comments from Sam Hiser, Gary Edwards and Paul Merrill.  Excellent review of the OOXML-ODF-CDF argument.  W3C CDF work was officially cancelled, July of 2010.  The long awaited "interoperability" version of ODF, known as ODF 1.2, was released to final consideration by the OASIS community in July of 2010.  That's about three years late.  Also, they did not fix the ordered list problem :)  ha ha ha.  Broken, impossible to fix with the OOo - KDE dual application approach.  Just like we said it would be.  Morons.

Excellent discussion of CDMA based 3G, Sprint WiMAX 4G, and Verizon's VERY limited capacity GSM LTE.  Keep in mind that Verizon is today an exclusive CDMA+ shop.  They do not do GSM (AT&T, Apple and most of the rest of the world outside the USA).  No mention of T-Mobile who has introduced a very fast and thick CDMA+ that is faster than WiMAX. excerpt: I'm hoping Apple expands beyond AT&T with Sprint instead of Verizon or, at least does what Samsung just did with the Galaxy S series - make an iPhone for all the major carriers. Why should iPhone be on Sprint? Here's five reasons:

Great links to HTML5-CSS tools and tricks excerpt: 3. Use Multiple Stylesheets for Device Support Including a mobile-specific stylesheet on your main site with certain parameters that add or subtract features, based on what device is being used, can be an elegant and effective way to serve content across multiple devices. Dominique Hazael-Massieux wrote a great article for A List Apart last year that covers some of the basics and also links to some of the most common parameters for handheld support. Dave Shea included his own solution back in 2008 that is still pretty usable for lots of devices. More recently, Chris Coyier at CSS-Tricks discussed how to add in screen size and browser support via CSS or jQuery, and he includes his own downloadable examples. Dave Calhoun has some excellent suggestions in his series on mobile web development.

This event speaks loudly to how little interest browser developershave in interoperable web solutions. One-way compatibility wins and the ability of web applications to round-trip data loses. For those that did not realize it, the Compound Document by Reference Framework not only allowes but requires that more featureful implementations round-trip the output of less featureful implementations without data loss. See http://www.w3.org/TR/2007/CR-CDR-20070718/#conformance ("A conformant user agent of a superset profile specification must process subset profile content as if it were the superset profile content"). 

Good Chart comparing four types of Data Stores: Key-Value, Tabular/Columnar, Document Store, Relational excerpt: The bottleneck is no longer around performance or the cost of computing - it's about quickly getting the information to thousands, or hundreds of thousands, of nodes trying to act as one computer delivering a service. Google and IBM both have written about the data center as a computer, and Facebook says it thinks of adding hardware at the rack level rather than at the server level. But the current means of storing and accessing data have not made this leap from a single server to a rack - let alone an entire data center. As programmers attempt this leap, they face several difficulties, which include working with existing software and programming languages and figuring out what problems and bottlenecks the new services built on these monolithic computer platforms will encounter. Plus, the IT world doesn't all move at once, which means plenty of jobs and workloads will continue with the old way of doing things - that is, relational databases such as Oracle's offerings and the open source MySQL, which Oracle now has a stake in thanks to its purchase of Sun. The result is not a steady movement to non-relational databases or other methods of storing data, but a back-and-forth as programmers and businesses figure out what kind of architecture they need and what problems they want to solve. For a closer look at the issue and a bunch of charts detailing how the landscape is currently laid out, analyst Matt Sarrel, has penned a report over at GigaOM Pro (sub. req'd.) on the NoSQL movement called "NoSQL Databases - Providing Extreme Scale and Flexibility."

Link is the latest version link so page should update when this specification graduates to a W3C recommendation.

Last year Bartz vented to me about Yahoo's infrastructure problems - the company, she explained, was a compilation of fundamentally disconnected vertical silos, each with its own P&L, codebase, infrastructure, and culture. It was nearly impossible to roll out products that cut across, say, Mail, Homepage, Finance, IM, Search, and Flickr, because each instance required custom integration and coding. Yahoo was literally broken underneath, even as it looked consistent at the UI layer. Add in the issues of internationalization, and you went from nearly impossible to "not even worth considering." That mean stagnation, and on more than one axis. For one, it means it's very hard to find leverage between your internal resources, or to roll out new products that build on more than one stack. For another, it means it's next to impossible to open your company's resources up to third party developers (there's that word) who might want to add value to the ecosystem you've created.

June 29, 2010 Dear College or University President: We write to express concern on the part of the Department of Justice and the Department of Education that colleges and universities are using electronic book readers that are not accessible to students who are blind or have low vision and to seek your help in ensuring that this emerging technology is used in classroom settings in a manner that is permissible under federal law. A serious problem with some of these devices is that they lack an accessible text-to-speech function. Requiring use of an emerging technology in a classroom environment when the technology is inaccessible to an entire population of individuals with disabilities - individuals with visual disabilities - is discrimination prohibited by the Americans with Disabilities Act of 1990 (ADA) and Section 504 of the Rehabilitation Act of 1973 (Section 504) unless those individuals are provided accommodations or modifications that permit them to receive all the educational benefits provided by the technology in an equally effective and equally integrated manner. ... The Department of Justice recently entered into settlement agreements with colleges and universities that used the Kindle DX, an inaccessible, electronic book reader, in the classroom as part of a pilot study with Amazon.com, Inc. In summary, the universities agreed not to purchase, require, or recommend use of the Kindle DX, or any other dedicated electronic book reader, unless or until the device is fully accessible to individuals who are blind or have low vision, or the universities provide reasonable accommodation or modification so that a student can acquire the same information, engage in the same interactions, and enjoy the same services as sighted students with substantially equivalent ease of use. The texts of these agreements may be viewed on the Department of Justice's ADA Web site, www.ada.gov. (To find these settlemen

Article discusses evidence that IPv6 adoption is accelerating and is poised to snowball. 

HTML 5 is a very hyped technology, but with good reason. It promises to be a technological tipping point for bringing desktop application capabilities to the browser. As promising as it is for traditional browsers, it has even more potential for mobile browsers. Even better, the most popular mobile browsers have already adopted and implemented many significant parts of the HTML 5 specification. In this five-part series, you will take a closer look at several of those new technologies that are part of HTML 5, that can have a huge impact on mobile Web application development. In each part of this series you will develop a working mobile Web application showcasing an HTML 5 feature that can be used on modern mobile Web browsers, like the ones found on the iPhone and Android-based devices

The World Wide Web Consortium's return to HTML standardization after years of absence has produced tensions with the more informal Web Hypertext Application Working Group (WHATWG) that shouldered the HTML burden during that absence. Some examples of language that's cropped up this month on the W3C's HTML Working Group mailing list: "childish," "intolerable," "ridiculous," "shenanigans." And there's a concrete manifestation of the divisiveness: The WHATWG and W3C versions of the HTML5 specification, though both stemming from the same source material, have diverged in some areas. Some of the differences are relatively minor, and there are strong incentives to converge the two drafts of the HTML5 specification so that browser makers and Web developers aren't faced with the prospect of incompatibilities. In the meantime, though, the overseers of the Web are clashing during a time when their important new standard is just arriving in the spotlight.

Jailbreaking vs. Unlocking Jailbreaking and unlocking the iPhone are two different hacks which allow you to take control of your mobile device in different ways. Jailbreaking is a type of hack that lets you install unapproved third-party applications on your iPhone or iPod Touch from searchable repositories provided by apps like Cydia and Icy. Unlocking, on the other hand, is a hack that lets you use your iPhone on another cellular network. Here in the U.S., that means you can use the iPhone on T-Mobile instead of AT&T. You have to first jailbreak your phone before you can unlock it, but you don't have to unlock a phone in order to jailbreak it. How to Jailbreak the 4.0 Software for the iPhone 3G and iPod Touch Second Generation The "Redsn0w" jailbreak software has been updated to support iOS 4.0 on both Mac and Windows and works for iPhone 3G and the iPod Touch, second generation. This jailbreak is especially helpful for for iPhone 3G owners as the new OS won't offer the much sought-after multitasking feature on their devices. A jailbreak application called multifl0w will, however, provide an alternative. Another jailbreak app called WinterBoard offers a way to customize the iPhone's background even though that too is disabled for 3G owners running the latest OS 4.0 update. This jailbreak guide assumes you've already downloaded and updated your phone or iPod Touch to the latest software, iOS 4.0, and have backed up your device. If you are looking to unlock your phone in order to run it on a network belonging to another carrier, this is not the guide for you.
