Optimizing Firefox Speed

There are several ways to make Firefox run faster. It’s all done by tweaking. I’ll be giving you a list of different tweaks, which will all count for something. Please note that I’ve done all of this on Windows XP Professional OS, and it may have different effects on other OSs.

This is the most popular way to make Firefox’s pages load faster, and no doubt you’ll come across this when you Google how to make Firefox faster.

1.

  1. In the Firefox browser, type about:config.
  2. You’ll get something asking you to be careful. Click the thing which is I’ll be careful, I promise!
  3. You’ll find a filter bar. Type network.http.pipelining under the preference name column.
  4. You’ll normally find the default value of this to be false. Double click it and change it to True.

Effect: For most (at least the ones I’ve all seen) websites, you’ll notice a http:// before the address. This is for something called the HTTP 1.1 , a protocol, this is so that you can send numerous requests before your computer actually receives them. It’s also known as pipelining. Pipelining can reduce page loading times over connections, but not all servers support it, which is why it will have no effect for some websites. For this to work, you need pipelining to be enabled.

2. In the filter bar, type network.http.proxy.pipelining  and its value to True.

Effect: Pipelining does not work when you are using a proxy. This is why you need to change this value to True, so that it is enabled if you are using a proxy.

3. Now type in network.http.pipelining.maxrequests. Right click and go to Modify. The default value is 4, change it to 8.

Effect: This determines the maximum requests your computer can send out at once. 8 is the maximum, so don’t change it to 100000 thinking you can send that much requests out.

4. Go to the normal about:config page, right click in the blank space and choose New/Boolean. Name this network.http.pipelining.firstrequest and accept. Then set its value to true.

Effect: This tweak isn’t normally recommended, but it hasn’t screwed my FF up in any way. It’s meant to aid in making your page load faster.

5. Now this time, right click and choose New/Integer . Name it nglayout.initialpaint.delay then accept. Then set its value to 0.

Effect: The initialpaint.delay is the length of time (in milliseconds) after the server response before the browser begins to paint, or create, the page.

6. Make another Boolean and call it content.notify.ontimer and set its value to true.

Effect: Normally, a page would load when each part of it has fully been downloaded. Instead with this, it will make FF display whatever has been downloaded and thus, reducing page load time.

7. Again, create a Boolean value and call it content.interrupt.parsing and set the value to False.

 Effect: This determines whether an application will “interrupt” a page being parsed so that it can react to the UI. Setting to false is so that the parsing cannot be interrupted, and the app will be unresponsive until all parsing has been completed.

There is another tweak for Windows XP and Vista users (except Windows XP Home Edition). This can be used for Internet Explorer and Firefox, or any other web browsing program. You’ll find this commonly over the internet.

  1. Go to Start
  2. Go to Run
  3. Type in gpedit.msc
  4. Expand the Local Computer Policy branch.
  5. Expand the Administrative Templates branch.
  6. Expand the Network branch.
  7. Open up the QoS Packet Scheduler.
  8. Double click the limit reservable bandwidth setting.
  9. Check the enabled item.

10. Change the limit to 0.

11. Close and restart your computer. 

This has your computer connect to your Internet faster as it has no limits to how fast you can connect to it.

[How To] Provide E-Mail Subscriptions For Your Blog Or Site

Description: This post aims to describe a way to provide Email subscriptions (daily) for your sites/blog’s readers using Google FeedBurner. The site used is my Blogging buddy’s blog, SoccerMatch. He asked me for advice on this topic, so I decided to write this tutorial in parallel to setting up subscription service for his site.

Firstly, new bloggers or site-owners might need to know what is a “feed”. There are several kinds of popular feeds on the Internet today, namely RSS (most commonly translated as “Really Simple Syndication” but sometimes “Rich Site Summary”) and Atom. These provide postings and updatings information for a “feed reader” that which can interpret can show that data as site content to the subscriber. These feeds need specific “readers”, either desktop-based, e.g. the Windows Vista “Feed” sidebar widget, or online-based, like My Yahoo! or Google Reader. FeedBurner can convert those feeds into emails so that the subscribers need not use a feed reader. To set up a email feed, follow the steps mentioned below.FeedBurner homepage

First, set up an account at FeedBurner, or you can log in with your Google Account since FeedBurner is a subservice that Google acquired in 2006. After you login, type in your blog/site home page (including the slash “/” at the end) in the box provided (see screenshot on the right).

Click Next and the “initial options page” is shown. You can type in your feed title (i.e. the title Initial settings pageshown in every email update sent), and the feed address, which is added to the end of “http://feeds.feedburner.com/.”
In our example, I typed in “soccermatch”, so the full feed address will become http://feeds.feedburner.com/soccermatch. After you’ve finished, click next again.

You can click next again to additional services. This will be covered later, so let’s click “skip Feed completed pagedirectly to feed management”.

Here you can do anything you want with your feed, but, as to make it simple, we’ll just set up a sidebar widget on the blog for feeds. Different blogging platforms will make Feed management homepagedifferent methods to install a link, but we need to get the code first. To do this, click “Publicize” on top of the page.

Publicize page

Then, click “Email Subscription” on the side of the page (see screenshot for link location). Click “Activate” on the next page.

Now you have your code in the next page! There are two options. You can choose to insert a form or a link to Copy Codesubscription page. Inserting a form causes some problems with some themes, so you’d better choose link (the latter option on the page). Now copy that code, and paste into a new HTML/Text widget in WordPress. If you don’t know how to do this, see this page.

For other sites, you just have to copy the code on any site template, it’ll automatically show up.

After you add your code and widget, a link to subscribe to your site/blog will appear in your sidebar. Click the link and Completed Linka form will appear to allow readers to subscribe to your blog/site. There are also a lot of additional features that FeedBurner provides. You can investigate yourself, or check back later to see a new article about the features of FeedBurner. To see what the resulting email looks like, subscribe to your own blog!

False Twitter Invitations Leading to Spyware?

I’m sure some of the people who read this post follow “Welcome to the Underground” Blog and maybe other blogs  by Twitter. However, did you know that some hackers send false Twitter invitations to lure people into installing spyware or downloading viruses?

Ever since Twitter became the major channel for information spread by Iran presidential election protestors, its popularity has rocketed upwards. Even the news of the Phoenix discovering ice on Mars was first announced on Twitter. However, all good things have a bad side. Cyber criminals are now sending false Twitter invitations to prompt installation of Trojans and virus worms!

From the format and content, the false invitations looks like that it’s a real one sent by the Twitter official site. However, if you look at it closely, you’ll find that the false invitation does not have the “inviting” link in contrary to the real invitations. In its place is a link that downloads a file called “invitation.zip” in the background that you cannot control, and lures the people who are considering joining Twitter into downloading the virus contained in the “invitation.zip”.

The virus in that zip file has been identified as a worm” W32.Ackantta.B@mm” by ESET nod32 antivirus (it’s definitelyNOT an email address!). This worm earlier appeared in February’s invitation card attack, which collects email addresses from the infected computers, and copies itself to those multiple addresses (this is how it’s supposed to work, but it’s usually blocked 90% by stronger av programs such as ESET or AVG).

I remind readers to upgrade their antivirus and communication software to prevent getting infected.

Soccer Manager.com — Free soccer/football management online game!

[Note: This review was written by Adrian, the Freeware Elite. You can visit his tech blog at: Freeware Elite.com]

Description: Soccer Manager is a free website on which you can manage a soccer team through your web browser. What make it different from other similar sites is that there is a very realistic transfer market for you to participate in. Actually, it is quite fun to put players on Loan Lists, Transfer lists, or just buy and sell players if agreed. There are also “Free Agents” which are players not owned by any clubs for purchase. There is also a “Score Centre” in which you watch your own matches progress. You need to be signed up to play.

Youtube — Only has name?

The American Times magazine elected the ten worse new tech ideas in the past ten years recently. For those on the list, some of them are quite familiar to most people, such as Vista, Zune, Palm, HD-DVD, Gateway,etc. However, even Youtube is on the list. Why?!

Actually, although Youtube is the largest video sharing site on the planet (now, there are 99 million people in the US that have visited Youtube before, and the total number of videos on the site is 5.9 billion), but Youtube has not yet found it’s regular income source! Google earlier claimed that Youtube, until now, still hasn’t a “real” profit.

Because the Youtube videos generally have bad quality, not much people are willing to advertise on Youtube. Albait the fact that, according to a company in Switzerland, Youtube has a profit of US$240 million, but their total profit was US$-470 million! They will have to triple the profit in order to make the balance! ARGHHH!

Overclocking NVidia Cards

Seeing as it is Exploitation Week, I guess I’d better do something. Considering that all my posts have been about tech, I guess I’m going to write for it and about something ‘techy’ for Expo Week. I’m going to write about overclocking your hardware. Today, I’m only going to talk about NVIDIA cards though, seeing as I don’t have much time.

I guess I’ll talk about and try teach the beginners how to overclock your graphics processor card (GPU).

Before I get fully into it, I must warn you that not all GPUs are good for overclocking. Some just simply aren’t powerful enough. If you want my advice on overclocking, you’d try get something in the NVIDIA GeForce 8000 series, 9000 series or any GTX. If you’re an ATI user, you can always just match up something close to NVIDIA’s with Google.

However, most cards under the 8000 series can overclock. But chances are you’ll screw the card up. The other problem is that you’re going to need a good cooling system.

Hamachi Networks – Left 4 Dead

Hamachi-SZ-128x128
Revisions: Initial Release.  I expect in the future to have these networks reduced again.  When L4D 2 comes out, expect the hamachi networks to get popular again.


Foreword:  On June 16th, many of the hamachi networks for L4D will be taken offline for good, due to lack of activity. If you want to still play online in Hamachi through our underground network, you can still do that.  Go near the bottom of the article for the network names and passwords. ~ Versatile

For the past few months, I have come to a revelation. Hamachi is a great tool when used correctly. When Left 4 Dead first came out, people were dying to figure out how to play this game online with other people. I started off in January 2009, and I had no idea about this Garena.com. From January through April, I played contently with Hamachi. Suddenly, someone asked me to make a tutorial about Garena, and although I was a bit reluctant in the beginning, I did it anyway. The rest is history.

Fast forward to present time. A lot of people have moved onto Garena to get their quick L4D fix (or whatever game). Unfortunately, that makes the remaining underground hamachi networks for L4D very empty. I understand that there are some people who cannot make Garena work (for whatever reason) and are requesting that I keep the hamachi networks online for their sake.

This is what we will do then. Discontinue the Voltaire networks (they weren’t popular anyway), and I will keep open these networks:

  • L4D Underground
  • L4D Underground 2
  • L4D Underground 3
  • L4D Troubleshooting
  • The password for all these networks = l4d

My L4D Is Updated and L4D Central hardly gets any activity, and I will be discontinuing it.  If you are against this plan, then voice your concern in the comments.  Thanks for your cooperation.

If you can, I suggest you move to Garena as there are people playing literally day and night, in all timezones.  Hamachi has a lack of people, and organizing a game is not very fun when there is hardly anyone on.

Conficker Virus – Set to Attack on April 1st, 2009

Have you heard of the Conficker virus?  It is set to wreak havoc on computers on April 1st, 2009.  What will it do? No idea, but I know it has infected PCs like the plague.  Will it steal your data?  Erase your hard drive?  Turn your machine into a spam bot?  We’ll see.

To make sure you don’t have the Conficker virus already, you can download various free scanners to scrub your hard drive for the virus signature. Using Google will help you find the programs.  If you can’t visit eset.com or any of the other anti-virus websites, hunches are you are infected.

Per lifehacker, you can protect yourself by:

How Do I Stay Safe?

Staying safe from this, and many other viruses and worms, requires a combination of keeping your computer updated and using anti-virus software. Here’s a couple of quick tips to follow:

Computer Chat – Hamachi Network

I never thought I would have to do this, but I decided to after having an interesting chat today in one of my other hamachi networks.  What happened today was I was talking to a fellow L4D gamer in one of my hamachi networks, and I soon found out that this particular individual knowledge about PC stuff in general was very lacking.

This person did not know he could partition his massive 700GB hard drive into smaller partitions, nor did he know he could dual boot his machine.  Knowing how to torrent was just something totally new, and he had no idea what msconfig was.

After spending almost 2 hours talking about random stuff, I figured out that it would be beneficial to host my own separate hamachi network to give underground help to fellow people.  Or if you are an expert like myself, join the network so we can learn from each other. ;p

The hamachi network is:

Network: Underground Chat

Pass: chat

Got a PC question?  Want to share your ideas?  By all means, join the network.  Perhaps we can combine our digital lifestyles into one massive learning experience.  See you there!

How to Jailbreak the iPod Touch 2G [2.2.1]

Hey guys.

So if you own an iPod Touch 2G (i’ll be lazy and might write touch), never fear, the jailbreak is finally here!

Ok, that’s not strictly true. The jailbreak has been around for awhile, but it was the tethered version, which required you to connect your touch to the computer every time you wanted to reboot.

A few days ago, someone was finally able to crack the final layer and make it such that you don’t need to tether the touch anymore. A few hours later, a program called QuickFreedom was built as a GUI to allow jailbreak.

All you will need is:

-QuickFreedom

-iPod Touch 2.2.1 firmware, which you can download online, through iTunes, or through QuickFreedom itself.

-LIBUSB (which you can install through QuickFreedom)

-an iPod Touch 2G (obviously.)

QuickFreedom works in a 5 step process, it’s actually not too hard to do.

Step 1:

You can download and install all the software you need from QuickFreedom, just make sure to refresh or restart the program when you do that so you can go onward, otherwise you will be stuck here.

Step 2:

Select your options and create a custom firmware. You can save it wherever you want, and you can add a custom bootscreen as well. When I did this, I didn’t use a custom bootscreen, but it should work fine.

Step 3:

This is the pre jailbreak. This was the hardest step for me, I don’t really know why. The whole trick is to get the touch into DFU mode. You can follow the DFU instructions, but it seemed almost impossible to use that, so I just ended up doing the DFU in various ways until I got it. I left iTunes open for the entire process, so you can use it as a check to see if you are doing it properly. It is my guess that QuickFreedom does not detect the DFU perfectly everytime since it told me that I was in DFU but would not let me proceed. Keep at it, you’ll eventually get there.

Here what I finally did at the end. It doesn’t matter if the iPod is on or off.
To do the DFU, hold the Power and Home buttons down for 10 seconds.
After 10 seconds, release the Power button and continue holding the Home button for 8 to 10 more seconds. At some point, iTunes should find an iPod in recovery mode unless you disconnected the iPod. I orginally tried doing this by turning off first, but in the end, I’m not too sure if that really mattered because my touch was in some limbo state between going on and off.

After you DFU, start the pre-jailbreak. WAIT. This is a mistake I almost made and got really lucky on. The log is there to help you, so read it! Do not go onward until you read that the patch was installed correctly. I almost started the next step before the patch was completely installed, this might screw things up, so just be careful.

Step 4:

Using iTunes, install the new software firmware that you built. Hold SHIFT and click Restore in iTunes, and find the custom firmware you built. Let the software install. It might take some time.

Step 5:

You are done! The touch should be jailbroken with Cydia and Installer. Have fun!

Some interesting notes:

I was not able to install more than 9 full pages of apps. I think that’s the limit. At 16 apps per page, thats 144 + 4 (from the dock) to total at 148. I haven’t tested this out, but you can probably use categories from Cydia to put all the apps in folders and get around this. Apps will still be there, but they are hidden away and will only appear if there is some more space (aka deleting old apps).

Thanks to the guys who made QuickFreedom and for http://proudofmylife.net, whose pictures I just copied because I was too lazy to screenshot my own in XP with Jing. If there is a problem, contact us.

Anyway, if you have questions, feel free to ask away! This worked perfectly for me and I’m happy with the results.

Voltaire.
