Console (TTY) Resolution on Ubuntu Linux boxes

Ubuntu installations come with 640 x 480 default config on console or TTY (Teleprinter/Teletype/Teletypewriter). To change that config to something readable:

– You need to edit /boot/grub/menu.lst
– To the end there are lines:
title Ubuntu 8.04.2, kernel 2.6.24-23 server
….
….
kernel /vmlinuz-2.6.24-23…

at the end of kernel /vmlinuz line we need to a new argument ‘vga’.

I mostly use vga=791

then update grub using:

# update-grub

and reboot.

What is Megaphone Desktop Tool?

Megaphone Desktop Tool is one of a kind tool that used mainly to support Israel and Jewish based online media attacks. This application is used by Jewish students and youth around the world to support Israel and attack critics of Israel in real time using online social bookmarking and comment pages. Although social bookmarking sites Digg’s TOS bans this kind of activity that would eliminate the natural way of public voice, this website has been active and working for Israel supporters to achieve their goal.

 A recent such ban came from Digg, social bookmarking website,  to a Palestine supporter who was only digging pages in favor of Palestine and burying the articles she disliked. She described this situation on her blog and explained the two sided policy of Digg by disclosing full details of Megaphone Desktop Tool.

GIYUS is acronym for Give Israel Your United Support. Here is what is displayed on the front page of GIYUS.org.
Today’s conflicts are won by public opinion.
Now is the time to be active and voice Israel’s side to the world.

Join the effort in 3 easy steps:
Download and install Megaphone desktop tool
Receive desktop alerts on key articles and surveys
Click alerts to easily voice your opinion
Help us by reporting relevant articles and surveys.

Together we can make a difference!
In case you don’t now about Megaphone, it is described in Wikipedia as “the pro-Israel lobbying software tool”. Here is an excerpt from the Wikipedia article on Megaphone.
The Megaphone desktop tool is a Microsoft Windows application distributed by the World Union of Jewish Students and other pro-Israel organizations, through the Giyus.org website. Released on July 19, 2006, it delivers real-time alerts about key articles, videos, blogs, and surveys to subscribers so that they can voice their opinions and work together to support Israel on the public opinion front.

So now you can see the relationship:
IsraeliGirl->founder of GIYUS.org->distributor of Megaphone->pro-Israel lobbying software->work together to support Israel

Opera Memory Usage Optimization Tweaks

After talking about Google’s newly released baby browser Chrome , I wanted to take a moment to talk my old loved one browser. Opera. I was an Opera user starting from 1998, hating IE’s limited browsing capacity, Opera was the relief. Opera was the multi-tasking, multi-tabing, multi-functionality (even that it had disable referer option and remove images with one shortcut – G) And then Firefox was born, IE’s long time battle had just started. Opera turned into a free web-browser but it didn’t help much usage wise because the addons and lacking open source community was big failure on Opera side.

After giving a little background on browser war, I want to talk about what I am using right now and why I am using them for.

-Firefox: lots of addons (webmaster tools, enable referer, google customize!!, ad-block)
-Opera: BEST RSS reader that talks to me so far. It is easy and convenient. Firefox is still missing a big portion on that.
-Maxthon: IE based, memory optimized and ads blocked, multi tabbing

Since I wanted to get back to my old habbit, RSS reading, I started using Opera again. and I ended up using 3 browsers at a time. Opera, Maxthon and Firefox. I was able to optimize Firefox’s memory usage greatly and now I’m getting best memory usage ever from Firefox but still lacking good RSS reader support. Opera is great for speed and RSS reading but I was having lots of issued with memory usage. I played with opera:config tab little bit and I want to share the experience with you.

My 2 cents for Opera Memory optimization:

  • Use a native skin;
  • Disable Automatic RAM cache opera:config#UserPrefs|AutomaticRAMCache (decreases memory usage); Disabling this helped me greatly to achieve memory optimization
  • Remove or disable unneeded plugins (i.e. Java & Quicktime);
  • Disable Smooth Scrolling
  • Disable Favicons – opera:config#Multimedia|Alwaysloadfavicon; (little but still good)
  • Disable fraud protection under Tools -> Preferences -> Advanced -> Security
  • Empty cache on exit.
  • Disable Bittorent support
  • Disable Opera Sync

Another set of Memory optimization tips that I didn’t test myself:

  • Disable thumbnails – opera:config#UserPrefs|UseThumbnailsinTabTooltips and opera:config#UserPrefs|UseThumbnailsinWindowCycle;
  • Disable PageIndex opera:config#UserPrefs|MaxVisitedPagesIndexSize;
  • Disable Speed dial (state=3) – opera:config#UserPrefs|SpeedDialState;
  • Disable Wand – opera:config#UserPrefs|EnableWand;

In order to get to the configuration section, you should open a new and type “opera:config” you will be able to see all the configs that is available to you for tweaking. One good hint on this is that search for “enable”. This query will list you the stuff that you can disable easily, like Bittorent support and Opera Sync.

Currently, on my Opera 9.62, when I search for enable, I have these options:

BitTorrent… …Enable
Disk Cache… …Enabled
Extensions… …Enable Canvas
Java… …Enabled
Network… …
Enable Content Blocker
Enable HostName Expansion
Enable HostName Web Lookup
Enable NTLM

Google Chrome Reviews

I was reading Matt Cutts blog about Google Chrome. He is the public face of Google and has been doing great job keeping it that way. This blog (Ten things I don’t like about Google Chrome) was a good proof of that.

After reading his blog and seeing comments, I wanted to add my negative views about Chrome:

Google Chrome might claim memory usage improved. I normally work with over 10 tabs at a time and when I open Google Chrome with 17 tabs (right now) it is using:
Pysical Memory: 385 MB
Virtual Memory: 430 MB

chrome.jpg

This is a real life usage of Chrome and total memory of 815 MB / 17 = 50 MB per page doesn’t really look optimum to me.

I recently optimized Firefox 2, applied the tweaks offered on websites. It started doing great job. I have all the toolbars and addons that give me great flexibility as well. Even Maxthon is far better then this memory usage. I say “even Maxthon” because it is based on Internet Explorer 6 and we know how extravagant Microsoft when it comes to memory and disk usage.

Seeing I was able to improve a lot with Firefox 2, another question comes to mind, why act arrogant and start a brand new project, make a new department and hire lot of engineers while you can be great help to improve Firefox? an ON-GOING, OPEN SOURCE PLATFORM…

-Chrome uses lot of disk space for caching. All the images on ‘Most visited’ page is stored in BMP format (or somewhere close that) each of those screenshots take about 1 Mbyte. After I used couple of days, when I checked cache disk usage it was almost 1 Gbyte.

I had cleaned Chrome folder and just fired up after I saw this thread:

12/11/2008 11:34 PM 25,989,120 History Index 2008-10
12/11/2008 11:15 PM 16,547,840 History Index 2008-11
12/11/2008 11:46 PM 2,600,960 History Index 2008-12
12/17/2008 11:27 AM 444,256 History Index 2008-12-journal

12/17/2008 11:27 AM 30,412,800 Thumbnails

I couldn’t find any place to change Cache settings so I am stuck with Google Chrome’s high disk usage.

-URL section is TERRIBLE. It might be a strategic idea for Google to combine URL section with Google Search Engine as default and capture more data from users. I changed that to just use history but even that when I try to find ‘typed url’ it takes forever because I have to delve into all my historical crap and find the one I’m looking for.

-Another bad thick with URL section is that if you type something wrong, it remains there. You are stuck with that thereafter, you can’t remove it, clean it but have to live it till it gets overwritten.

I haven’t found any good addons for Google Chrome that will help my browsing experience. So far best part of Google Chrome is rendering speed. It has been doing great job with Ajax based javascript heavy loaded websites.

So final word is Google Chrome has achieved to get %2-3 of web browser portion in very short time but still lots to go and I am very reluctant to use unless above issues get fixed in new releases.

Multiple Session for Remote Desktop on Windows Vista

Previously I had mentioned about enabling Multiple Session for Remote Desktop on Windows XP This time I’d like to talk about Multiple Sessions for Remote Desktop on Windows Vista.

Multiple Session for Remote Desktop on Windows Vista Ultimate, Enterprise and Business Vista x86 (RTM & SP1) and x64 (RTM & SP1)

  1. Download Termsrv.dll file http://rapidshare.com/files/135672441/VISTA_TERMSRV_PATCHES.zip for
  2. Extract files to a folder and run setup.cmd file. Once it runs, it takes care of other details that you would have typed manually.  If you’d like to know what you would be doing manually if you were not running this command, it is listed as below:
    Type the following & hit enter: takeown /f C:\Windows\System32\termsrv.dll
    Then type this & hit enter (NOTE: Replace USERNAME with YOUR USERNAME!):
    cacls C:\Windows\System32\termsrv.dll /G USERNAME:F
    Then go to your Windows Explorer, and go to C:\Windows\System32\
    Rename the original termsrv.dll to something else, like “termsrv.dll.ORIGINAL”, just in case
    NOTE: If you are unable to do the above, try rebooting into SAFE MODE
  3. Assuming you ran the setup.cmd file, in the middle of its execution it will ask you to copy Termsrv.dll file, you should copy the file from the right folder depending on your Windows Vista installation.

Then you’ll also need to create another user. Remember, this doesn’t let you connect 2 people to the same user account, so make another account & then just connect to that one & you should NOT be disconnected.

Thanks to PCTuren you can also use the exe version which supports:

Works with Windows Vista UltimateWindows Vista BusinessWindows Vista Home PremiumWindows Vista Enterprise Edition.
Works with  Windows Vista 32-bitWindows Vista 64-bit versions.
Works with  Windows Vista Original ReleaseWindows Vista Service Pack 1
Works with Windows Vista Enterprise Edition
