I doubt IE will ever fully pass Acid3, unless they change their mind on a few things.

Mainly font-face support, IE already supports that part of the spec, but only their own format, Acid3 tests font-face but uses a format IE doesn't (and apparently wont ever) support.

Serious?

Acid3 don't mean anythng in real world at present and near future, innovation, security, performance to name just 3 things are far more important.

These test should be for developers only, as at present its mis-guiding the ignorrent to how good browser is.

Rendering engines don't innovate. If they do, they're typically proprietary innovations and should, for that reason, be avoided. Cross-browser innovations occur in W3C standards, which build upon previous standards. Those must be well-supported before you can build upon them because you cannot build off a foundation until the foundation can support what you build. That is why the Acid3 test is so important. Innovation on the web depends on decent browser support for current standards. It's no coincidence we are still waiting for CSS 3, HTML 5, and XHTML 2, for example.

I agree with you that speed is important, and that also ties into idea of providing a foundation for innovation. The Acid 3 test reports on speed. In fact, you must render accurately and swiftly to pass the test.

As for security, that too is incredibly important. But working to pass the Acid3 test does not detract from it. The development teams for the various browsers will, generally, drop what they are doing and improve security if they perceive a need to do so. Acid 3, nor the encouragement to pass it, affect browser security.

As for the idea of the test being developer-only, I disagree completely. The only way most web developers can have a say about the progression of the web is if they can gather people together for a cause. There's a reason why random griping across the internet led to only small changes but the introduction of the Acid tests led to rapid progression ;)

Well they can innovate, but they do it within a certain framework that allows everybody to benefit.

The Mozilla guys are working on a way to treat any arbitrary element as a image for stuff like background-image, the Safari guys already have something similar, but just for Canvas tags. In both cases though, they've written out documents detailing how it works, then have gone around talking to other browser makers for comments.

<canvas> started off on a similar route, it's now part of HTML5.

Edit: Compared to how IE does it, when they mention in release notes they've created a new method of doing something, when there's already an incompatible spec going through the W3C and has browser implementations (like FX3, it was cut at the last minute due to changes in the draft)

But..

Failed 0 tests.

I think IE8 has come A LONG WAY recently and i'm really impressed with it. I would actually consider switchign back from Firefox to it if it keeps this up. Although i think it would be a great move, expecially for the IE haters, if they passed ACID3 i think the fact they have now passed ACID2 is great news.

True... but I think in non-web applications it was very much underused and most people used IE to do any of their data retrieval stuff.

If it hadn't have been embedable in a web page and used via javascript, it probably wouldn't have really be used at all.

I can get anywhere from 75/100 to 79/100 in Chrome and all those Chromium builds every time I refresh, so it doesn't seem to be really improving on Acid3 yet. Never got one 80/100 yet.

And yes I got 79/100 the first time I run Acid3 in the first beta release of Chrome three days before.

who wants to test firefox 3.1 alpha 2 with acidtest 3, i dont wanna install on my pc as my add-ons wont work with it.

...

FX3.1 gets 85/100 and only "fails" one test due to the time it takes (FX3 "fails" a whole bunch due to time)

I use the nightlies, it probably hasn't increased since then (I was using a newer build than A2 though)

    • DuRoBo Krono Review: Portable E-Ink reader with great ideas that need a bit of improvement

      By goretsky · Posted

      Hello, While ~104 GB of space may seem generous (at least compared to other e-readers which have 8-32GB), I feel at this price point the device should have a Micro SDXC card slot for expansion, particularly if it allows audio books to be installed and played. I hope to see more reviews of 6" phone-sized e-readers on Neowin in the future. It will be interesting to see how they compare. Regards, Aryeh Goretsky
    • Sandboxie Plus 1.17.8 / Classic 5.72.8

      Sandboxie Plus 1.17.8 / Classic 5.72.8 by Razvan Serea Run programs in a sandbox to prevent malware from making permanent changes to your PC. Sandboxie allows you to run your browser, or any other program, so that all changes that result from the usage are kept in a sandbox environment, which can then be deleted later. Sandboxie is a sandbox-based isolation software for 32- and 64-bit Windows NT-based operating systems. It is being developed by David Xanatos since it became open source, before that it was developed by Sophos (which acquired it from Invincea, which acquired it earlier from the original author Ronen Tzur). It creates a sandbox-like isolated operating environment in which applications can be run or installed without permanently modifying the local or mapped drive. An isolated virtual environment allows controlled testing of untrusted programs and web surfing. Sandboxie is available in two flavors Plus and Classic. Both have the same core components, this means they have the same level of security and compatibility. What's different is the user interface the Plus build has a modern Qt based UI which supports all new features that have been added since the project went open source. The Classic build has the old no longer developed MFC based UI, hence it lacks support for modern features, these features can however still be used when manually configured in the Sandboxie.ini. Sandboxie Plus 1.17.8 / Classic 5.72.8 release notes: Added added DisableCustomTitleOpt=[process,][y|n] to allow [#] sandboxie title markers on custom-titlebar windows (Delphi VCL, Qt, Electron) that were previously skipped to prevent DWM repaint CPU loops #5387 Changed updated bundled ImDisk driver to 3.0.2 #5419 Fixed fix Suppress logs for expected non-user SIDs #5422 SbieSvc.exe: SBIE2218/2219 error when run program as administrator #5417 fixed explorer.exe crashes in Application Compartment when Huorong Security is installed #5423 Download: Sandboxie Plus (64-bit) | 23.5 MB (Open Source) Download: Sandboxie Classic (64-bit) | 3.0 MB Links: Sandboxie Website | GitHub | ARM64 | Screenshot Get alerted to all of our Software updates on Twitter at @NeowinSoftware
    • what other retro software do yall use

      Hello, Christian Maas' XVI32 is a nice (and very small) hex editor. Speaking of hex editors, many years ago a colleague and I who both worked at Tribal Voice managed to edit a copy of the company's PowWow instant messaging client to make it behave better now that all of its lookup servers and other server-side tech was gone.  The program didn't support NAT (RFC-3022 was introduced in January 2001, the same time Tribal Voice was shuttered), but it still worked okay if you manually set up port-forwarding on your router.  The server at http://powwow.jazy.net/ hosts a copy (usual warnings about downloading and running untrusted code from random internet servers apply). I occasionally use some tools like Funduc Software's Search and Replace and Application Mover when I need to make mass-edits to text-based files or move programs with a hard-coded installation directories, respectively.  When I need to figure out the exact LCD panel inside of a laptop, EnTech Taiwan's Monitor Asset Manager is my go-to tool for that purpose. JD Design's website (now hosted on github.io) has a number of interesting freeware and shareware utilities.  I used to use their TouchPro utility to set the file timestamps on software I was mastering to match its version number (e.g., version 3.00 of a program had all of its files dates set to 3:00AM, and so forth). Karenware has a number of interesting freeware utilities, too. Regards, Aryeh Goretsky

      I still use HexChat! Not really as ancient as the 1994 AutoCAD above my post, but I have never found anything better to replace it. Yes we still operate an IRC server https://www.neowin.net/irc/ 😛

      At work we still have a couple of people that use a version of AutoCAD LT purchased in 1994. This predates Windows 95 and works fine on versions of Windows up to XP. Its long since run in an locked down isolated XP VM, accessible via RDP. I did install LibreCAD for them, however they said it was just too different to get to grips with. In all fairness one of them is now 75 and the other is almost 60.
