yanyan writes "I'm fairly new to the field of web application development. Currently I'm working on a big online ticketing system for passage and freight for a local shipping company. It's a one-man show and the system is written in Ruby and uses Rails. Aside from the requisite functionality of creating bookings the system must also print reports and tickets, and this is where I've discovered (the hard way) that most, if not all, browsers fall short. I've had to switch from Firefox 3.6.3 to Opera 10.53 because of a major printing bug in Firefox, but the latest stable Opera is also giving me its own share of problems. To complicate things, an earlier version of Opera (10.10) doesn't appear to have 10.53's printing problems, but I'm wary. What browsers and specific versions do you end up deploying for use with big, complex web apps that include printing? Also consider CSS accuracy and consistency."

Anonymous Apcoheur writes "Scientists from CERN and INFN of the OPERA Collaboration have announced the first direct observation of a muon neutrino turning into a tau neutrino. 'The OPERA result follows seven years of preparation and over three years of beam provided by CERN. During that time, billions of billions of muon-neutrinos have been sent from CERN to Gran Sasso, taking just 2.4 milliseconds to make the trip. The rarity of neutrino oscillation, coupled with the fact that neutrinos interact very weakly with matter, makes this kind of experiment extremely subtle to conduct. ... While closing a chapter on understanding the nature of neutrinos, the observation of neutrino oscillations is strong evidence for new physics. The Standard Model of fundamental particles posits no mass for the neutrino. For them to be able to oscillate, however, they must have mass.'"

1sockchuck writes "Iceland's supply of renewable power has gained a high-profile international data center customer. Web browser developer Opera Software was announced today as the first customer of the Thor Data Center, which will house Opera's servers in data center containers that can use fresh air cooling, rather than chillers (a strategy also used by Google). The Thor Data Center is located in Hafnarfjorour, to the west of Iceland's ash-spewing volcano. Iceland's data center operators insist their location represents no operational risk from volcanic activity."

SergeyKurdakov writes "Monty 'xiphmont' Montgomery of the Xiph Foundation says the latest action-packed, graph- and demo-clip-stuffed Theora project update page (demo 9) is now up for all and sundry! Catch up on what's gone into the new Theora encoder Ptalarbvorm over the last few months. It also instructs how to pronounce 'Ptalarbvorm.' Ptalarbvorm is not a finished release encoder yet, though I've personally been using it in production for a few months. Pace on improvements hasn't slowed down — the subjective psychovisual work being done by Tim Terriberry and Greg Maxwell has at least doubled-again on the improvements made by Thusnelda, and they're not anywhere near done yet. As a bonus Monty gathered all Xiph demo pages in one place." Also on the video codec front, and also with a Xiph connection, atamido writes "Google has released On2's VP8 video codec to the world, royalty-free. It is packaging it with Vorbis audio, in a subset of the Matroska container, and calling it WebM. It's not branded as an exclusively Google project — Mozilla and Opera are also contributors. Builds of your favorite browsers with full support are available." An anonymous reader points out this technical analysis of VP8.

An anonymous reader lets us know of an experiment conducted in Norway to determine real-world problems in using IPv6 today (Google translation; Norwegian original). "According to a Norwegian article in digi.no, Redpill Linpro did an experiment with regard to IPv6 on one of the largest online newspapers there (www.vg.no). They added a hidden iframe that pointed to an IPv6-enabled domain to test real-life problems about the reported IPv6 holes. The result was that mainly Mac OS X, older versions of Opera, and a few Linux distributions exhibited problems. For Mac OS X it took 75 seconds to time out before failing back to IPv4." From the consultant's report: "Mac OS X has a problem in that it will prefer 6to4-based IPv6 over IPv4-based connectivity, at least if its local IPv4 address is an RFC 1918-based private address as commonly found in NAT-ed home network environments. This is unfortunate, as 6to4 has shown itself to be much less reliable than IPv4."

mattcsn writes "Opera Software just bought email service provider Fastmail.fm. Here's hoping that Opera uses a light touch and keeps the email service as unchanged as possible. From the article: 'FastMail has included a FAQ, in which it says that users who wish to not transfer their accounts over to Opera have to go into settings and indicate just that. Not acting upon the email the company sent out to its users or actively accepting the transfer will result in Opera assuming control over the mailbox and the account registration details. As to the reason for selling, FastMail says the market was getting increasingly competitive and that Opera's expertise in web browsers and especially the mobile market would help the company grow and take on the next big challenges in running and building an email service.'"

Stoobalou writes "Everyone was mightily surprised when Apple allowed Opera entry to the iTunes App store, but there's one very good reason for the change of heart. Opera Mini for iPhone is not very good." I tried it for a little while, and the one thing that I really liked is how insanely fast switching tabs was.

Crazzaper writes "I have been using Firefox for many years, and the war of the browsers has been around for longer than that. It just so happens that now we have a lot of options out there: IE, FF, Chrome, Opera, Safari, and others. People are always talking about how one browser is going to take down another, but maybe that's not the issue at all. It seems very possible that one browser, like Firefox, can be taken down by multiple browsers at once, whether or not there was any intention to compete specifically with Firefox. I hadn't seen it this way, but I do now."

An anonymous reader writes "Opera Mini for iPhone was officially submitted to the Apple iPhone App store today. A select few first saw it at Mobile World Congress 2010 in February. Now, the 'fast like a rocket' browser is taking its first big step towards giving users a new way to browse on the iPhone."

TheReal_sabret00the notes a TechRadar piece reporting that Opera Software has seen a doubling from normal download numbers on average since Microsoft's browser-choice screen lit up in Europe. The UK saw an 85% increase and for other countries it was larger still: Poland 328%, Spain 215%, and Italy 202%. Hakon Wium Lie, CTO of Opera Software, said "A multitude of browsers will make the web more standardised and easier to browse."

gollum123 tips an article at the NY Times on the progress of the European Windows browser choice screen that we have been discussing recently. "Rivals of Microsoft's market-leading Web browser have attracted a flurry of interest since the company, fulfilling a regulatory requirement, started making it easier for European users of its Windows operating system to switch. Mozilla, whose Firefox browser is the strongest competitor to Microsoft's Internet Explorer worldwide, said that more than 50,000 people had downloaded Firefox via a 'choice screen' that has been popping up on Windows-equipped computers in Europe since the end of last month. ... Opera Software, based in Oslo, said downloads of its browser in Belgium, France, Britain, Poland, and Spain had tripled since the screen began to appear. Microsoft said it was too early to tell whether the choice screen might prompt significant numbers of users to change. The digital ballot is being delivered over the Internet with software updates, and it is expected to take until mid-May to complete the process. The browser choice will also be presented to buyers of new Windows computers across the European Union for five years."

An anonymous reader writes "After seeing Opera's claim to 'Fastest Browser on Earth' after their most recent release, Tom's Hardware put Apple Safari 4.04, Google Chrome 4.0, Microsoft Internet Explorer 8, Mozilla Firefox 3.6, and Opera 10.50 through a gauntlet of speed tests and time trials to find out which Web browser is truly the fastest. How does your favorite land in the rankings?"

Kelson writes "Have you noticed that there haven't been many updates to Gears in a while? That's because Google has decided to focus instead on similar capabilities in the emerging HTML5 standard: local storage, database, workers and location cover similar functionality, but natively in the web browser. Of course, since Gears and HTML APIs aren't exactly the same, it's not a simple drop-in replacement, so they'll continue supporting the current version of Gears in Firefox and Internet Explorer. I guess this means the long-anticipated Gears support for 64-bit Firefox on Linux and Opera are moot."

netux writes to mention that Opera has released Dragonfly, their answer to Firebug, as an open source project under the BSD license. The release features a complete architectural overhaul using a modern version of the Scope Protocol (STP-1), a Mercurial repository on BitBucket, and a Wiki to get the ball rolling. "This is Opera’s first full open source project, so there will be a learning curve. We ask you to bear with us while we get everything up and running and policies in place. Coming from a closed source background there are some hurdles to overcome, such as the current bug tracking system being on a closed server. We hope to migrate to an open bug tracking system as the project gets on its feet."

Luchio writes "Finally, a little bit of respect from Adobe with this alpha release of the Adobe Flash Player 10 that was made available for all Linux 64-bit enthusiasts! As noted, 'this is a prerelease version,' so handle with care. Just remove any existing Flash player and extract the new .so file in /usr/lib/mozilla/plugins (or /usr/lib/opera/plugins)."

Opera has released its 10.5 beta (for Windows only; Linux and Mac coming). Opera calls 10.5 "the fastest browser on earth," but the jury is out on this claim. WebMonkey says that the new beta feels snappy in their informal testing. Both CNET and ZDNet ran two quick benchmarks that measure JavaScript performance, SunSpider and V8. ZDNet found Opera beating out Chrome in SunSpider but lagging in V8. CNET found Chrome ahead in both tests. What is clear however is that Opera's Carakan JavaScript engine has made up much of the ground in the performance wars; The Reg estimates that 10.5 is seven times faster in the JavaScript stakes than Opera's shipping 10.1 release.

Barence writes "Opera is launching a version of its Mini browser for the iPhone in what could prove a landmark decision for Apple's app gatekeepers. Apple has been traditionally hostile to rival browsers, with Mozilla claiming that Apple made it 'too hard' for its rivals to develop a browser for the iPhone. However, Opera remains bullishly confident that its app will be approved. 'We have not submitted Opera Mini to the Apple App store,' an Opera spokesperson told PC Pro. 'However, we hope that Apple will not deny their users a choice in web browsing experience.'" I can't imagine what would motivate them to do that.

r3lody writes "Sams Teach Yourself HTML and CSS in 24 Hours 8th edition, by Julie C. Meloni and Michael Morrison, provides the beginning and intermediate web designer with the tools needed to create standards-based web sites. The major focus of the book is XHTML 1.1 and CSS 2, but HTML 5 and some XHTML 1.0 are discussed. Overall, the presentation and content are very good. One small minus was that the publisher's site did not include downloadable examples from the book. I also found no errata until the latter parts of the book. Published in December of 2009, the 8th edition provides reasonably current information." Read on for Ray's review.
