The Incredible Speed of the Internet (You thought your FIOS was fast)

March 19th, 2009 206 comments

I just thought I would brag about the insane speed of Virginia Tech’s internet.   It has been slower recently due I suppose to more traffic, but it is still insane compared to most places.

Update: While being here for Summer Session I was able to attain the picture above.

During the Fall I was able to get this to go from 40000-60000, but as I said its been slower now.  Still, where else but a college campus would you find this.  I had dial up until 2 years ago, then we finally upgraded to DSL, which I still regret using on breaks now.  It is soooo slow compared to this.  Just for comparison, DSL usually returns about 200-700 kb/s on Speedtest. We have 99 percentile of the global internet connection in terms of speed.  BTW, the LHC (Large Hadron Collider) has “data outputted by blasting it through dedicated 10 gigabit-per-second fibre optic lines to 11 Tier 1 sites across North America, Asia and Europe.”  That is the epitome of fast.

Neccessary Windows “Run” Commands

December 22nd, 2008 199 comments

Through Windows very pretty GUI file explorer it is sometimes hard to remember that some powerful tools can be hard to find through it, but are readily available through the “Run…” link that can be found on any Windows XP Start Menu.

MSCONFIG

I will begin with one of the most useful commands and programs I have found on not only speeding up my computer’s boot time, but also allowing those annoying sneaky programs from starting up before they even have a chance.

First go to the Start Menu and click “Run…” or press the Windows Key and R at the same time.  Both will bring up a prompt in the left-bottom corner of the screen.  In this box type msconfig.  A new box should pop up and should look like the screen below.  If you have never edited this before, the Normal Startup radio button should be selected.

From here click on the Startup Tab and you should be presented with a list of items like the one listed below.

startup

These are the are the non system necessary programs that start up with your computer.  You may see ones for various anti-virus programs such as the avgtray item listed above.  You may uncheck whichever ones you like, but only try to uncheck ones you know are absolutely unnecessary to your computers normal operations.  I don’t take responsibility for errors due to the unchecking of any of these entries.

Another way to view Startup programs is to get to the “Run..” prompt again and type in the box “C:\Documents and Settings\All Users\Start Menu\Programs\Startup” without the quotes.  If there are any programs are in there that you don’t want starting up you can delete them.  Also, you can put shortcuts to programs in here such as shortcuts to Batch files you want running at startup.

SERVICES.MSC

First go to the Start Menu and click “Run…” or press the Windows Key and R at the same time.  Both will bring up a prompt in the left-bottom corner of the screen.  In this box type services.msc.  A new box should pop up and should look like the screen below.

services

These are the various services that your computer runs.  If you right click on an entry you will see the menu that is shown above.   If you want extended information about each service, go to the “extended” tab on the bottom left hand corner of this window.  There are several columns listed by default describing each service and services can be sorted by each category by double clicking on the name of that column.  The Name column obviously shows the name of the service and the Description one shows the description of the service.  The Status of the service shows whether it is active or not shown by whether the service is started or not.  The Startup Type shows whether the service is set to start up with the computer or when needed (Automatic),  requires to user to start it (Manual), or is disabled from working at all.

Now if you right click on a service and go to Properties, you will be shown a box just like below.

properties1

If the program is running it will have the option to Stop the program and if the program is on Manual but not started then you can Manually Start it here. The Startup type dropdown box allows you to choose whether to make the serrvice be Automatic, Manual, or Disabled.  In this case I disable the Messenger service because this program is notable for showing spam on your computer.  There are multiple sites online that sell Messenger ads that are spammed to millions of users around the world who have this service enabled.  It was originally made for communicating on a network but has been exploited in multiple ways.  I suggest you disable this, but again you take your own risk when disabling any service and mess up your computer in any way.

CMD

One way to get to the famous Command Prompt is to go to the “Run…” prompt which you should know how to get to by now and type in cmd.  This should bring up the command prompt in all its glory.  I will do another post some other day on the usefulness of the Command Prompt.

REGEDIT

One of the most powerful tools on the computer, but also one of the most dangerous is the Registry Editor, accessed by typing regedit into the “Run…” prompt.  I will not go further into the Registry editor at the moment, because of the severe damage it can cause to your computer if anything wrong is done with it.  It is however a database of all settings and configurations for most if not everything that runs on your computer.  I may do a separate post on this someday.

Other Things to Do

GPEDIT.MSC

To access the group editor and change permissions or settings for users you can type gpedit.msc in the “Run…” prompt and play around with it.

File Browser

The “Run…” prompt can be used as a file browser by typing in the location of any folder.  A Explorer viewer will popup once you have pressed enter.

A Ridiculous Claim

December 15th, 2008 209 comments

I was reading through Slashdot the other day and came across a link to this article: Linux Stop Holding Our Kids Back

It is about a school teacher who confiscated HeliOS disks that a student was distributing during class and claimed that their is no way software could be free.  As an avid user of Firefox and a fairly recent user of Ubuntu Linux, I must say that this is definitely a very cruel thing to say to the society of people who has work extremely hard toward the open source community.  She even claimed to have used Linux in college and that she knows nothing is better than Windows and that free software must be some sort of copyright violation.  This article shocked me and made me realize just how powerful the computer monopoly mostly held by Microsoft really is.   Just to let everyone else know, yes there is a free Operating System called Linux and it is available in many shapes and forms all over the internet.

The followup to that article is here

Free Web Hosting

December 12th, 2008 512 comments

So for all of you amateur webmasters, I would like to provide some free web hosting links so that you can get building a website as soon as possible without worrying about who to get hosting from.

Free Web Hosting

-Places where you can get free web hosting for hosting a site of your own.  The following I have personally used.

• Frihost
A free web host with 250 megabytes of space and 10 Gigabytes of monthly transfer. They require you to post on their forum in order to keep your site up. They offer PHP 5 and unlimited mysql database. They also support ftp. There are also no ads on these sites because the host has ads on their forum. Their hosting server is usually up.
• Dhost
Deluxe Host has 100 megabytes of space but a whopping 300 Gigabytes of monthly transfer. They allow only one mysql database, but also offer PHP 5. They have ads on their sites, but not too annoying. Their hosting server is usually up, though some downtime lasts a logn time.
• Hostultra
This site has popup ads but they have unlimited transfer and space. They offer PHP but no mysql unless you pay a $5 one time fee.
• 50 megs
They offer 50 megabytes of webspace (as the name suggests) and 1 Gigabyte of monthly transfer. They have ads at the top of their pages. This site used to be hosted here.

-Places where you can get free web hosting for hosting a site of your own. The following I have NOT personally used.

Host On Us
Supposedly they offer:

  • Powerful DirectAdmin control panel
  • Full FTP access
  • PHP scripting
  • MySQL Databases
  • and much, much more!

These are only suggestions. If you happen to find something better, please feel free to comment.
