Attempted to read BIOS 128KB: got 0KB

Filed under: gentoo, hard — Tags: , , , , — admin @ 12:49 pm

Or how to loose a few hours on trying to setup dual monitors with a on-board nvidia and PCI Matrox card.

The problem on the end was that when the primary card (nvidia) was not set as the primary boot card, it was not setup right by the bios and hence X could not access it, so just setup nvidia back as the primary card, and voila, wonders work.

How to Remember IP addresses More efficiently?

Filed under: Uncategorized — admin @ 12:30 pm

Okay I was developing a new website (which I won’t reveal just yet), and I needed a way to generate user logins for people who are lazy.

The thing is I know that if I want to make a good service I need to get past one thing, and that’s creating logins and passwords for people who just want to try out the service.

But, my service will have a sub domain for each new user, so just creating xhf235ssfd.mydomain.com does not make much sense, does it? Now, next thing is I will assign them unique id’s in the program, which will be determined by the data base’s auto_increment, so using a number.mydomain.com makes much more sense, but numbers are not so easy to remember, plus it looks much more ugly then having something with text. And imagine that it could be pronounceable?

Then it striked me, I recall a program which generated OTP passwords by converting numbers to mnemonics so it can be transmitted between 2 humans over a phone line just like a service to give one-time testing access. I searched and searched on my drive, but having 68Gigs of data in my home directory makes it… well a little difficult. So I went on the ‘net and found this crazy page called IP Mnemonics (here a blogpost).

It’s a cool concept, basically a ip which is 87.230.21.3 would be get.tin.bet.add which also has only 4 syllables! Pretty awesome, and I found a list which I can use to convert my sequential numbers to something nicer then just random garbage, hex-codes or a integer.

I will copy the list of numbers->names here in case the original site ever disappears.

Which Version Control System and Bugtracking system to use?

Filed under: medium — Tags: , , , — admin @ 4:48 pm

After reading a bunch of articles about Request Tracker, and other Issue Tracking Systems starting from here on wikipedia and and on slashdot .

And before anything watching this amazing video:

From which I got a hint that git could be the way, I found this post which basically confirmed my research that Git and Trac are the way to go.

Now I’ll be installing and testing it in the future, so we’ll see…. I’ll keep you posted.

VMWare Alt Key gets Stuck

Filed under: medium, vmware — Tags: — admin @ 3:14 pm

There seems to be a bug in VMWare, at least in Linux when you switch back and forth between the Guest and Host sometimes the Alt key gets stuck in the Host, where in the guest the key is not stuck. This simple script solves the problem:

#!/bin/sh
/usr/bin/xmodmap – << XXX
clear shift
add shift = Shift_L Shift_R
clear lock
add lock = Caps_Lock
clear control
add control = Control_L Control_R
clear mod1
add mod1 = Alt_L Alt_R
clear mod2
add mod2 = Num_Lock
clear mod3
clear mod4
add mod4 = Super_L Super_R
clear mod5
add mod5 = Scroll_Lock
XXX

Just run it and it will clear the stuck keys.

HOWTO: Remote Desktop through a proxy

Filed under: medium, proxy, routing, windows — admin @ 2:46 pm

Ok, the problem is simple, you are in China for example and you have a really bad connection from your hotel to your Windows Server or your home computer via a rdesktop connection.

Luckily you have a proxy server somewhere (for example a squid), but rdesktop has NO settings for a proxy server, and it ignores the proxy settings in Control Panel….

Luckily someone pointed me to a nice program with which you can configure a proxy for a program which does not even support a proxy, meet Proxy Firewall, direct download link here .

vmware: D-Bus not built with -rdynamic so unable to print a backtrace

Filed under: medium, vmware — Tags: , , , , , — admin @ 1:20 pm

This happens on Gentoo’s vmware-workstation ebuild installation, like explained here and here the problem is you have dbus running, but not hal, simply add hal to your default startup:

rc-update add hald default

run it:

/etc/init.d/hald start

and retry the drill with vmware.

Can Google follow <form>?

Filed under: google, html — Tags: , , , , — admin @ 9:48 pm

I somehow had the impression that it can’t or that it does not, whatever. But not from my own beliefs, more from what I heard from other people, but I never bothered about that.

Actually I never heard anyone claim that it can do just that, but for me it was kind of a normal thing. But recently I was checking a site in Google Webmasters Tools, and it had some problems with certain links while crawling. The links were of the type somepage.php?something=that Where I had no idea who would have linked to that since that was available from a dropdown in a form which actually not even had a button but was submitted via onchange=”this.form.submit();”. (which could also mean that Google does know to read and execute javascript, but that’s I’m going to explain in one other post) Anyway, I searched for back links to the site containing that parameters, and found it. So I first thought it’s just a coincidence, and I solved the problem by redirecting the call back to the original page when the new information was saved in the session data. But this fix triggered the same problem on some other page which before that had no error reports, and this page is surely not receiving much visitor traffic, so I really Doubt that someone did post a link to that one in the meantime.

Conclusion, yes it knows and does follow forms, at least it seems so :)

MP4 Player

Filed under: mp4 — Tags: , , — admin @ 6:20 pm

Playing MP4 Video Files In Windows

MPEG-4 is quickly becoming one of the most important formats for video on the Internet. MPEG-4 files typically have the extension .MP4 and are created by a large number of software tools, digital cameras, and mobile phones.

There are number of free programs that can be used to play back MP4 files in Windows. Unfortunately, they can be difficult to find because searching for “MP4 player” in search engines often gives results which are not useful because they point to no-name software that may contain adware or spyware. “Adware” is software which displays advertisements to the user, either while they are using the software, or in more annoying cases by popping up windows even when the software isn’t being used. “Spyware” is software that is used to track and record a user’s actions (such as the web sites that they visit) and then report that information across the Internet to some person or business (perhaps for the purposes of showing “targeted” advertisements that are meant to be relevant to the user’s interests). Spyware and adware are often bundled with other applications and installed without asking or informing the user first.

The following packages, however, are all reputable software and do not contain any adware or spyware:

QuickTime

QuickTime is the name of Apple’s video technology. They make a player application which is free to download. It is also included with iTunes (because iTunes makes use of QuickTime). You might notice that Apple also talks about “QuickTime Pro“. This is a paid upgrade which adds functions to the player for converting video to different formats (including MPEG-4).

Advantages

  • Very easy to use.
  • Works inside your web browser, making it easy to watch MPEG-4 video on the web, such as the excellent quality movie trailers provided by Apple.
  • Made by a major software company.

Disadvantages

  • Player supports all types of MPEG-4 video, but doesn’t support many other common formats.
  • QuickTime is more demanding on the computer’s processor than the other options listed here. Processing MPEG-4 video can be demanding so this may make a difference on older computers (especially with larger videos).

VLC

VLC is a popular free media player which is available for many different types of computer. It works with a huge number of different video and audio formats.

Advantages

  • Can play many different types of video file, including most AVI files, WMV, MPEG-1, MPEG-2 and MPEG-4.
  • VLC is fast. If you have an older computer then it may be able to play videos smoothly which cause QuickTime Player to stutter or skip.

Disadvantages

  • VLC is very powerful software and has advanced features like format conversion and hundreds of different options. These might be daunting for first-time users.
  • VLC is free and open-source software which is made by volunteers, not a software company. As such, they do not hold patent licenses for the various patented video formats that are supported by VLC. This means that, depending on where you live, you may need to obtain patent licenses yourself in order to be able to legally use VLC.

CCCP

CCCP is the Combined Community Codec Pack. A codec is a piece of software that is used to play a particular video or audio format. CCCP is a free collection of various codecs and other pieces of media software, which can be used to play back many different kinds of video. This option is interesting because it uses the media system that is built into Windows (called DirectShow), and so it makes Windows Media Player (and some other media software) able to open the new formats.

Advantages

  • Allows you to use Windows Media Player, which you may already be familiar with.
  • Uses the same core decoding software as VLC, so it is just as fast.

Disadvantages

  • CCCP is a collection of many different pieces of software that work together. This makes the installation somewhat complicated, and may be daunting for people who are not used to using video software. It is also possible for there to be conflicts between the codecs installed by CCCP and codecs which are already installed on the computer (although the installer tries to eliminate these conflicts).
  • Has the same patent license issues as VLC, because it is also created by volunteers.

It’s funny that things like this:

Have a low View count. Even if someone things these guys are wackos, I guess they are better then these guys:

But the thing is, the first has 91 views at the time of this writing, and was added Jan 7, the other has 53,xxx and was added Jan 3, and I hardly believe the few days have such an impact… rather the topic…
