Mozilla Firefox memory optimization

Firefox is getting very popular lately, mainly due to its customizability. I use firefox as my main browser and use all sorts of addons which help me in web-development. These addons make my firefox hungry but I can’t do without them. So, instead I tweaked around some settings in firefox which made it much responsive and faster than before.

To tweak those settings, follow the following steps:

1. Type about:config in your address bar and hit enter.

A trick to get access to protected sites.

Sometimes, when you search in google for something, you find very nice results but when you visit those sites, they seem to be protected i.e; you need to either sign-up or maybe you need to pay for it. So, here’s a way to get access to it without paying or even signing up.

Mostly people want their exclusive content to be protected. Since it is exclusive, they would want people to know about it so that more people join the site. That is why they let search engines to access their protected content so that it gets listed in their results and site gets traffic for that. Now search engines are similar to people. Websites only have one way to differentiate between them – User agents. All the search engines have user agents which makes them differentiate from humans.

A guide to remove any kind of viruses

Being attacked by many viruses in the recent times, I thought why not make people learn from my experience. Having faced about a dozen of different viruses in past 2 weeks, I have experience enough to write this guide. I faced trojans, trojan downloaders, rootkits and what not. So here’s my little guide which will help you get rid of your virus.

We’ve got a huge amount of viruses floating over the internet. New viruses are being made by evil programmers daily. Due to this innocent computer users are being infected and suffering from infected system which results in compromising of private data, destruction of data, unusability of computer etc. For non techy people virus removal is a tough task. Fortunately, for tech-savvy people its not so difficult.

I am writing this guide so as to help people from removal of viruses from their computer.

A brief introduction about viruses. A virus is generally a malicious software which tries to steal personal information from your computer or uses your computer for other malicious activities like spamming, used as proxy from illegal activities, spreading malware etc.

Computer can be infected from virus through many means. You can get infected from a mail you opened from unknown person, some software installation, a friends pen-drive which you just inserted in your computer etc.

Until now, only Microsoft Windows have been known to be infected by viruses. Linux and Mac OS remains unaffected. There are only few known viruses for them. Windows on other hand has thousands of viruses with new viruses being produced everyday.

To protect yourself from viruses you will need to have many tools.
Tools required:

1. Sysinternals Process Explorer.
2. Good anti-virus software (preferably Kaspersky, NOD32, or Norton).
3. Malwarebytes Anti-Malware
4. Registry Fix.
5. Task Manager Fix.
6. UnHackMe.
7. Lavasoft Ad-Aware latest 2009 version. (Older version has many drawbacks)
8. HijackThis
9. Spybot S&D. (Optional)

Most of the viruses won’t let you know when they install themselves on your computer. You won’t even notice them unless they do something noticable like use internet extensively which draws your attention etc.

When you get infected by a virus and you are sure about it:
You know that you have been infected by a virus and you don’t know what to do. Just bear with me and you will find quick solutions to your answers.

To check if virus is using the internet:

1. First of all check if it is using internet. Go to Start Menu-> Run -> Type “cmd” without quotes and enter.
2. Then type “netstat -b” without quotes in the console and press enter.
3. On the left hand side, you will see a list of executables and right to that, you will see the sites it is connecting to. If you see any unknown executable connecting to any unknown site. It means that it is using your internet. In this case, I recommend disconnecting from internet to protect yourself.

Modifying Fervens’ (Wordpress Theme) width

Fervens is an extremely attractive and excellent theme for wordpress. After trying numerous themes, I settled for this and its really really amazing.

The only shortcoming was that its main content area was too small. On larger posts, the content would span upto numerous pages which would’ve not taken so much space if it had been a little bit wider.

I tried to experiment with the theme and modify it for greater width. It was not a difficult task and moderate knowledge in CSS is enought to make it accomplish. For the rest of you, I will teach you how to do it.

GMail inbox full, now what? I’ve a solution

My Gmail inbox space was almost completely used last week. I needed to delete mails to free up space but didn’t have much time. So what I did was made a new gmail account and forwarded all my incoming mails to the new account. This saves me from the trouble of telling every other person about my new email address. Everyone can email at my old address and I will recieve them at my new address.

Permanently moved to my new web address

After buying new domain http://www.techmindz.com, my older domain was still accessible. I had completely abandoned its usage, but two days ago, I visited it just to check and was amazed to see its page rank had gone to 2. I was shocked and spellbound. I admit that I had done some intense SEO myself, for it. But still I hadn’t expected its page rank to go up in such a short span.

Spent some bucks on my forum

So, I had collected around 100$ in my paypal and was planning to collect it and buy a good laptop. But, I also wanted to invest it on my forum’s marketing and SEO (search engine optimization). I thought to myself that it would take a long while to collect for laptop. So, I decided to spent some money on my forum’s promotion. I found out one search engine optimization who provided 8200 Directory submissions for 50$ along with 1 article submission to 25 high PR sites. I liked this package. I contacted him and sent him the money.

I was hesitant in spending the money but it was not spending after all, it was investment. I would get the result back in form of popularity and more traffic which would eventually be converted into more money.

Fight with a virus.. it was terrible

Yesterday, I was infected with probably the ugliest breed of virus in computer history (atleast, for me). What it did was nothing serious. I downloaded something off the internet and ran it. Spybot gave me a warning about a registry entry and I knew it was virus. I simple denied it. It again popped up after few minutes. It confirmed that it was a virus because no other software would prompt again for the registry entry. I denied again and no matter how many times I denied, it came back again after a few minutes. So, I knew it was a time for scanning. I scanned and deleted atleast 12 virus executables created in various system folders. I deleted them all. I think the virus injected itself into some system executables too. And I deleted those files too. Everything was going fine. The virus was listed as Win32/Kryptic.AA trojan and WIN32/Rootkit.Agent by my NOD32 AV.

An alternative to cross-domain AJAX, sort of

Recently, I got a project to make an ad system for a website. The ad system was such that, when the page displaying ad was loaded for the first time, it would create a random link and store them in database. From then on, it would display the same link on same page.

So, I made a javascript file which would create and xmlobject for AJAX request. It would query php file on a server and get the link. But cross domain AJAX just doesn’t work. I tried to edit some parts of it, but it just wouldn’t work. Cross domain ajax requests aren’t allowed for security purposes.

So I had to think of something else. First I thought of renaming php file to js and then addind a code to .htaccess to make it behave like php. Then I thought of making image links dynamically using php’s GD library.
