Once in a while you go to check out your personal website, or to log into your company web email and you can't. For the average person going about their daily tasks this can be stressful and what to do can be even more confusing. How do you tell if its your computer or its the website itself, maybe its just a blip, or maybe you should contact somebody! If you are part of a small organization, you may be the only one who has noticed, and you won't be able to access the system until somebody is alerted of the problem.
This tutorial is a troubleshooting tutorial. My goal is to help you find out if is the computer, the website, the webserver, or the internet that is at fault, and who you should contact depending. Some people take the troubleshooting to mean doing something techincal, but the goal in troubleshooting is to test possible problems and eliminating the most common and simple problems first.

Most people remember buying their computer, and usually there was a point where you had to decide based on price what processor you wanted, and how much RAM, or memory it has.
If we were to compare a computer to a car the processor is the engine, and the RAM is the cabin space. The processor is all about speed. How many computations does a processor make in a second. The faster the processor the higher the rpm, or the bigger the engine. The memory is like cabin space in a car because the more RAM your
computer has (to a point) the more programs it is capable of running.
Much like the bigger the interior of the car, the more people you can, probably, comfortably fit
I'll explain more about it once we have gotten your processor model and your amount of ram.
There are two steps to finding this information in Windows, lets start with step one!

Finding out how much space is left on your computer or how much space you have on your computer total is something very simple, but it can also sound daunting. This tutorial will take you through the process in under a minute.
If you are using a Windows machine, XP, 2000, 98, or Vista it really doesn't matter, the steps are the same. If you are using a Mac they are similar.

This is a very basic set of steps that I would follow to set up Ruby on Rails so you can do the 15 minute rails blog tutorial on a ubuntu desktop.
Here is a 15 minute blog tutorial. It shows the simplicity of rails, but doesn't talk too much about installation and database configuration. There are other such tutorials on the web, but this one I thought was good.

From my prior doc
Rails Mongerl and Apache All togerher now 1 I created a very basic rails application, mostly for the purpose of displaying text, and maybe some images afterwards. I am going to run mongrel which I installed with
gem install mongrel
to see whether what I wrote displays through mongrel. I run
script/console
Which runs mongrel on port 3000. So I navigate to
http://jibwa.com:3000/photo
and I get XML back
Now I know my Rails is working properly and is rendering form the db. Now I need to get apache

I spent a lot of time looking at ways to run rails on Apache a few months ago. Whether or not there is an easier way to to it I think this is the best way to do it.. I am running a fully updated Redhat 5 Rackspace Server
I have done all this before but its been a while so I am just going to do a fresh application and get it runnning some basic code, and then get it live. If you already have a working app you can skip down. I do this all from a bash command line.
First I go to my rails app directory
cd /home/jbwhite/rubyprojects
mkdir photoalbum
rails photoalbum
Now Rails is installed and I have to make a mysql database and configure that.
mysql -u root -p
>create database photoalbum_development
>grant all on photoalbum_development to rbuser@localhost identified by 'password'

I have been working on an Excel 2003 Workbook with about 10 Sheets, and about 50 pages of visual basic scripts. The actual data content shouldn't be all that big because the worksheets are relatively small. I spent a lot of time trying to find ways to reduce the file size and nothing seemed to help until I found a posting on mrexcel.com about the

I had an explot hit a site that wasn't on one of my servers and there wasn't an backup availalbe to resore from. Still having to fix this I decided to write a script to inspect all the files and remove the bad text. Mostly the exploit appended an iframe at the end of files, but I wrote my script to remove particular text no matter where it sat in the file.
I wrote a bit about a python file structure crawler and I'll include my whole method below for reference.

I needed to crawl a directory structure and get a list of all the files with their absolute location, I think the easiest way to do this is with os.path.walk. The syntax is a little confusing at first, but it works fine and I end up with the list of all files with their folders from whatever location I start at.

I spent the better part of a week trying different tutorials and ways to get my Radeon 9700 set up to work with Ubuntu Desktop 7.10. (Advance Desktop Effects are a must) All the tutorials I found were steering me in so many directions I called an expert to see what he thought was the best way. He reccomended I simply revert everything back

The process was pretty painless getting windows installed. After the install I looked at options for connecting to the XP box. Some suggested VNC, but I settled on using Remote Desktop since it is native to XP and it doesn't require any additional software installations.
So once you isntall windows make sure to install VMWare Tools, In the VMware Server Console, Be first to comment this article |
