Firefox 29: Redesign

Antiocheian Re:more downgrades (688 comments)

I have used my voice reader many times with Pale Moon and works perfectly. I have studied Firefox's accessibility features list and I haven't found anything that isn't supported by Pale Moon or the OS. I am using Pale Moon with font override for months since I don't want to give web authors another means to connect to Google for custom fonts.

I didn't care for the optimizations either, though people in the forums claim the gains are tangible. I started using Pale Moon after Firefox v4 because I didn't like re-editing my userchrome.css file every time Mozilla decided that Firefox needed a face lift.

Google's Blogger To Delete All 'Adult' Blogs That Have Ads

This is about Google eliminating non-Google adult ads on Blogger sites.

That's an interesting answer. But I was always under the impression that it was Netscape who didn't play fair at the IETF while Microsoft did. Of course behaving at a standards body and actually adhering to the standards are two different things...

Greek Government Abruptly Shuts Down State Broadcaster

Antiocheian Re:Night night liberty (230 comments)

You are probably not aware that ERT (Elleneki Radiophonia Teleorassi) was the only allowed TV/Radio station in Greece for many years. In fact when CNN announced its plan to broadcast in Greece by satellite in the 80s, a minister of the Socialist government threatened to "shoot" it down.

ERT is the most iconic symbol of an old, despotic, union-owned state that is finally breaking down.

Scanner Identifies Malware Strains, Could Be Future of AV

Antiocheian Re:And when whitelisted code gets hacked ? (70 comments)

1. Yes, an iPhone can be hacked to become a computer, but the default configuration to which your original posting was referring to, is not a personal computer but much closer to a smart terminal since it can't function properly (and by functioning properly I naturally have to include running code) without receiving the approval of a central computer. The point of my counterargument is that while Apple's whitelisting system is working fine on the iPhone, the uses of the iPhone are not as broad as the uses of a personal computer.

2. There is already a security application that acts in the way you propose: Comodo. Now, Comodo is an interesting issue in your argument because it has repeatedly failed in respected antivirus tests such as AV Test, AV Comparatives and even VB100 (which is as close to the defacto standard as it can be). It failed so bad, that it had to be removed by those tests to avoid further embarrassment.

3. Java is not the issue in browsers, since it's not part of the browsers but a plugin instead (which can be forced to work inside a sandbox as Mozilla did for Flash). Javascript is the problem since it's a real programming language that can be used to strech a browser's code to its limits and turn any flaws to possible code execution. I don't think you can whitelist websites from Javascript as well.

Finally, while sandboxing protects the rest of the system it doesn't prevent a hacked application from accessing your data and posting them through the internet.

I'm not invalidating your argument, but I wish to point out that whitelisting may work for some users who use a limited number of applications and even then it won't offer them the complete protection they would hope for. Modern high quality antivirus suites offer superior solutions without restricting the user's choice of applications.

Hawking explains how to make a time machine

Antiocheian Antiocheian writes  |  more than 4 years ago

Antiocheian (859870) writes "Stephen Hawking describes, in the Daily Mail, how to build a time machine. "All you need is a wormhole, the Large Hadron Collider or a rocket that goes really, really fast".

The article deals with potential issues, such as time tunnels being a bit small for a human to enter: a billion-trillion-trillionths of a centimetre. It also explains what would follow a successful launch in a wormhole:

"The initial acceleration would be gentle because the ship would be so big and heavy. But gradually it would pick up speed and soon would be covering massive distances. In one week it would have reached the outer planets. After two years it would reach half-light speed and be far outside our solar system. Two years later it would be traveling at 90 per cent of the speed of light. Around 30 trillion miles away from Earth, and four years after launch, the ship would begin to travel in time. For every hour of time on the ship, two would pass on Earth. A similar situation to the spaceship that orbited the massive black hole. After another two years of full thrust the ship would reach its top speed, 99 per cent of the speed of light. At this speed, a single day on board is a whole year of Earth time. Our ship would be truly flying into the future.""

TSR's Letters to some anonymous FTP Sites

Antiocheian Antiocheian writes  |  more than 4 years ago

This is one of the letters TSR sent to anonymous FTP sites in 1994 to force them to remove AD&D related material. It wasn't only meant to remove copyrighted material. Anything bearing an AD&D term such as "THAC0" or "Greyhawk" was infringing, according to the letter, and was meant to be removed. Some people in the AD&D-L mailing list asked TSR which terms were infringing and the response they got was to hire a lawyer.

Mr. Dayton,

My name is Robert Repp. I work for TSR, Inc., makers of DUNGEONS AND
DRAGONS products. In the course of looking through the public FTP site at
Portland State, I came across a directory pub\frp\*. This directory appears
to contain an older mirror of the MPGNet FTP site. Contained within this
directory are several files which contain trademarks and copyrights owned
by TSR, Inc.

Among these files are several PLAYER'S HANDBOOK entries reproduced in their
entirety, several net.books which contain TSR copyrights and trademarks,
and properties owned by several other publishers.

While I cannot speak for other companies, on behalf of TSR, Inc. I must ask
you to remove all of these files from your site. They infringe on TSR
copyrights and trademarks, and should not be published from your site. We
have licensed MPGNet's FTP site at ftp.mpgn.com to be the sole carrier of
TSR trademarks and copyrights on the Internet at this time. If you wish to
contact them regarding moving your collection to their site, please email
David Brooks (dbj@mpgn.com) for information.

Please feel free to contact me at any of the addresses listed below, or by
voice from 9am to 5pm CST. I will gladly try to answer any questions you
may have regarding this matter.

Mr. Fiarito

I connected to jove.cs.pdx.edu today, and was dismayed to find that your
administrative staff has still not removed several files which infringe on
TSR trademarks and copyrights. Further, I found a notice (see below) which
states the administrator's intention to keep and disseminate several of
these files. I must warn you that these files clearly contain
infringements, and that they cannot lawfully be published from your site.

For your convenience, I have listed several sample files which infringe on
TSR copyrights and trademarks. This is not a complete list, but rather
meant to give you some idea of the material in question. Also, your site
appears to be mirroring a European site which is carrying several
questionable files. I will direct an appropriate note that site's
administrator. In the meantime, you should be aware that these files remain
problematic, regardless of their country of origin. Republishing foreign
files doesn't abrogate the need to comply with domestic regulations.

I remind you that we have licensed a site to carry TSR trademarks and
copyrights on the Internet (ftp.mpgn.edu). If you wish to keep your
collection intact and public, I suggest that you email Rob Miracle at
rwm@mpgn.com and make arrangements to transfer your holdings en masse.
Otherwise, they should be made inaccessible to the public.

I am in anticipation of your prompt reply.

(draft notes) Mediacoder - Shame & Viruses

Antiocheian Antiocheian writes  |  more than 4 years ago

(draft notes)

What the hell is going on with Mediacoder ? It begun as an open source project of great promise, an FFmpeg UI for Windows that could also encode & mux Nero's AAC to mkv and mp4 and also combine Mplayer for resizing and cropping. But then the author started closing the sources piece by piece turning himself to the FFmpeg hall of Shame. And he started playing around with malware.

Here are some reported cases of viruses and malware in Mediacoder; they have been taken from the Mediacoder support forum (it's quite possible that the author will remove them from the forum in time)

Virus.Win32.Induc found in MediaCoder FullEdition 0.7.1.4490
Postby Vboy  Wed Aug 19, 2009 1:13 pm

I was just scanning my whole computer today and my antivirus was detecting "Virus.Win32.Induc" in MPUI.exe file in the codecs folder of Mediacoder :shock: Just so that its not a false positive, uploaded it to virustotal and the result is 17/41 (41.47%) :(

Here is the link http://www.virustotal.com/analisis/6244923a25f148ff00cb909401baa91da64ee2f119c3af816b22785d8f884d62-1250658289

I downloaded MediaCoder FullEdition 0.7.1.4490 from the mirror http://www.mcex.org/dl/MediaCoder-0.7.1.4490.exe , and it downloaded few more files during setup. Actually when i first installed it offline and there were many missing files, to fix it installed it while online and it downloaded those missing files. Can some one explain what is going on here ???? First a spyware and now a VIRUS ??? Is this a false positive or what ??? :x :evil:

MPUI is removed since 0.7.1.4495. MPlayer's built-in GUI is used instead.
Hopefully this MPUI virus doesn't do much harm.

Sure Stanley, an innocent error.

Adware detected in installer

Postby pelle  Tue May 19, 2009 3:45 am
Doing a manual scan of the installer (v0.7.0.4399 - Full Edition) gives this with Eset NOD AV 4.0.424. Installer was downloaded from Sourceforge.

Number of scanned objects: 507
Number of infected objects: 1
Number of cleaned objects: 0

D:\Downloads\MediaCoder-0.7.0.4399.exe  NSIS  rkinstall.exe - Win32/Adware.Agent.NMA application

The v0.7.0.4395 installer gives no such warning.

Extracting the v0.7.0.4399 installer with UniExtract. VirusTotal gives this result (20/40 (50.00%))for the rkinstall.exe located here (\MediaCoder-0.7.0.4399\$TEMP\$TEMP\rkinstall.exe)

Report form VirusTotal:

Most likely a false postive but can you verify the validity of the file rkinstall.exe contained in the installer?

I had the same answer for the same file.
Hope someone can tell us if rkinstall.exe is safe.

RkInstall.exe is truly a adware, but I don't understand why Mediacoder has it.
Someone can tell me what is going on?
Open Source is the most powerful way to spread knowledge.

It won't be installed BECAUSE IT WON'T BE (SUCCESSFULLY) DOWNLOADED!

Most people sane enough to use a virus checker have it set to scan anything being downloaded and to reject anything containing undesirable material.

Suggest you QUICKLY RETHINK this action - once the software package (and you) garner a reputation for inappropriate conduct, it will be irreparable.

You are killing the goose - I doubt you will find a collection of golden eggs.

TrendMicro's detection of PAK_Generic.001 is obviusly a mis-reporting.

AntiVir reports latest MediaCoder AE has a virus

Postby nosignal  Tue Dec 02, 2008 5:05 am
AntiVir 8.2 reports MediaCoderAE-0.6.2.4210.exe contains the signature of a "Pakes" file dropper. It has info on two related Pakes variants (I can't post the link exactly): www dot avira dot com

I could find no evidence of these drops, but I may not have been clever enough.

AntiVir is one of the most respected Antivirus programs out there. Assuming MediaCoder is safe, it is still quite a pain having AntiVir nag me about a virus on regular occassions, and many users could be put off.

However, today when I logged in I had a Windows Defender alert displayed for the downloaded EXE file above.
AVG Antivirus Free also did not find anything on the system. So it may be possible that this is a false positive.

I'm running Windows 7 public RC and AVG Free antivirus along with the built in Windows Defender. All spyware and virus definitions are up to date as of today.

How I improved energy savings on my nVidia 8800 GTS

Antiocheian Antiocheian writes  |  more than 6 years ago

The following is a walkthrough for a better power management of nVidia 8800 GTS video card (it will work on most nVidia or ATI cards). Experienced RivaTuner users only need to read this: you can achieve better power management if you depend on the video memory usage instead of the hardware acceleration boolean for your high frequency / low frequency switching.

I didn't like nVidia's own energy-saving settings because they didn't save a lot of energy as temperatures were still quite high when lower energy settings were enabled. In particular, the build-in energy saving

  1. Does not change the memory frequency at all
  2. Does not lower the GPU frequency too much
  3. It is disabled whenever a "hardware acceleration" call is invoked

All the items are self-explanatory but #3 needs some further attention: most CPU-based power management depends on CPU usage; that means, when you use your CPU intensively, it is switched to higher frequencies and voltages. There is currently no utility (or, more importantly, hardware call) to measure GPU usage. Therefore an alternative has to be found.

Nvidia's alternative is the hardware acceleration boolean. This boolean is switched on when 3D hardware acceleration features are being used, otherwise it is disabled. Therefore, nVidia's theory is that when 3d acceleration is required, then the your card should go to full power mode.

This is a bad idea because playing a video on a standard video player or a simple game with minimal 3d acceleration requirements will invoke such calls, yet neither of these require more than 1% of the monstrous 8800 GPU. (Windows Vista is using pixel shaders and therefore it invokes hardware acceleration calls all the time, but I am not using Vista and neither should anyone interested in saving energy).

On the other hand, video memory provides a much better source of data to rely on. With a few exceptions (mostly diagnostics and some benchmarks) demanding games will require a lot of video memory while non-demanding games (or video playback) will require small amounts of video ram. My threshold is set to 98 MB. Anything that requires more video ram will work on standard speed, while anything that requires less will work on energy saving settings.

Interested? You'll need:

  1. A standard or modified Forceware driver (version 150 or higher)
  2. The RivaTuner utility from Guru3D (version 2.08 or higher)

And this is what we'll do:

  1. Enable monitoring of various metrics
  2. Create a standard profile
  3. Create an underclocked profile
  4. Automate switching between profiles based on the video memory usage

1) Enable monitoring of various metrics

Install RivaTuner. And go from the Main tab to Target Adapter, Customize..., Hardware monitoring. Click on the background monitoring button (red button like Record on bottom left) and click on Setup, Plugins. Enable the VidMem.dll plugin. Click OK and tick on the Local Videomemory usage of the data sources (you are still on Setup, right?). It is also not a bad idea to tick on Core clock, Core clock shader and Memory clock to see what is going on. Click OK and inspect your graphs for a moment. You can close the hardware monitoring window and it will monitor the data sources on the background as you've set it up.

2) Create a standard profile

Now go to the Power User tab and change the RivaTuner\Overlcokcing\Global\MinClockLimit setting to 9. This will allow you to specify really low frequency settings. Go to the Main tab and open the System tweaks\Overclocking tab; save your current (default) clocks as a preset with the name "HIGH CLOCKS". You'll need this later.

3) Create an underclocked profile

Now it's time for some underclocking; set your Core clock and Memory clock to a low frequency combination (such as 128 Core /200 Memory) and click on "Test" to see what happens. It will probably be fine and you should hit "Apply" after that. If you wish try a lower combination. I use 80 Core / 80 Memory and I am fine with that.

Make sure those settings are enabled on both standard 2D and performance 3D settings (combo box on the top of the window). Now watch a video clip, play a game or run a short 3D speed test. Naturally reported FPS will be quite low (although not as low as you expect, a proof on how fast these cards really are). If all goes well (and I don't see why it shouldn't) go back to the System tweaks /Overclocking tab and click on apply overclocking at Windows startup and save it as a profile with the intuitive name "LOW CLOCKS" or something like that.

Note: newer versions of the Forceware drivers allow over/under clocking of the shader domain clock. You should change that as well for even better energy savings.

4) Automate switching between profiles based on the video memory usage

The point is that whenever you play a demanding game, your standard settings will have to kick in, otherwise you should be on the lower and cooler clocks. That was quite difficult with RivaTuner but fortunately the good (and donation-deserving) author has improved it a lot.

Go to the Launcher tab and click on the plus icon; choose Regular Item and type the name "HIGH CLOCKS" (again). Tick the "Associated overclocking profile" and pick the "HIGH CLOCKS" item from the combo box beneath. Click OK and do the same for the low clocks profile.

We are almost done; go to the Scheduler tab and click on the plus icon. Use the following settings to create the low clocks launcher:

Launch: item
Name: LOW CLOCKS
Run task: on hardware monitoring threshold event
Data source: Local videomemory usage
Threshold: 98
Direction: downward
Display threshold on hardware monitoring graph: yes (a bright color will be fine)

and another launcher for high clocks:

Launch: item
Name: HIGH CLOCKS
Run task: on hardware monitoring threshold event
Data source: Local videomemory usage
Threshold: 99
Direction: upward
Display threshold on hardware monitoring graph: yes (a bright color will be fine)

That's it. It's done now. You can play a game and you'll see no difference because the standard clocks will take place. While working on the desktop though, you'll notice much lower temps (and lower fan noise) on your card.

It's a shame nVidia didn't pay greater attention to energy saving. It's not only an issue of doing something for the environment; keeping the temperatures of the video card low means that you keep the general system temperatures low. It also means that less heat is dissipated from the card which results in lower (if any) air conditioning bills for those living in warmer climates.

It would be really great if nVidia published an updated BIOS to automatically lower power settings based on the GPU usage instead of video memory. nVidia could also switch the voltage settings which means that the difference between low clocks to standard clocks would really be huge.

Thanks for reading; comments will be welcome.
