Now if only I could center a div that has an absolute positioning

What is RAM?

So the Hot One, my wife, comes to me the other day with a flyer in her hand..."Is this laptop a bargin?"

"Sure, but you'll need more Ram", I said.

"Why" says the 10 year old.

"It'll run faster", I answered.

Now, what most people want to know is "How much do I need", here is the short answer: 3GB.

And here is the long answer. Most people may vaguly remember that RAM is memory. However, I like to think of it as the ability for a computer to multi-task.

The more RAM a computer has the better it will be at multi-tasking. You see, each program and application you open will request an amount of RAM for its own exclusive use. This is ok, but at some point the computer has no more to give. Now, being a good tool, the machine does not stop working, but it does start running slower. And as you keep opening windows it will get slower and slower.

So in conclusion, the more RAM you have the "things" you can do with your machine without affecting the speed.

Like all rules, this one has an exception. Some programs when they load, go ahead and take up all available RAM. You know who these greedy beast are before you even fire them up...cause usually they are the only thing you have open. Examples would be: 3D games, Virtual Boxes and Development environments.

The other time that RAM really comes into play is on start up. The computer needs to start a million things at once...to speed this up it constantly swaps part of the programs being started into and out of memory. The more memory you have the more it can switch and swap.

Here's a quiz for you... What can you do to speed up your machine, without spending money on new "hardware"?

Why Flash is Not a PBBG

A lot of folks ask me what "games" I develop. I tell them I make Persistent Browser Based Games (PBBG), their eyes promptly gloss over and I promptly move along.

However, there are some few folks who know what I'm talking about. This post would be for those select few.

Flash games are not Persistent Browser Based Games.

A PBBG is the defined as the following (from pbbg.org)

A persistent browser-based game, or PBBG, is a computer game that satisfies the following two criteria:

1. It is browser-based. The game is played over the Internet using only a web browser.
2. It is persistent. Progress in the game is achieved over multiple playing sessions.

PBBGs merge the depth and longevity of an application-based game with the accessibility and portability of a browser-based game. PBBG can be spoken as pee-bee for brevity.

Notice the explicit use of the word only .

Flash requires a plug-in, regardless of which browser a user uses. Thus it is out. Even if the game itself is "persistent". Now, flash can be an added bonus/feature to your game. But if a user needs flash to play your game then its no longer a pbbg.

Flash stay in your genre or make your own.

Why is this important to me?
PBBG is a different art from flash development. I like the fact that PBBG development requires you to understand all the three levels of web development. It also assist you in growing skills that can be used in a more "professional" environment.

Flash on the other hand, can more easily blur the lines in the three levels of web development as well as cut some corners on some fundumental development skills that professionals need.

If someone comes to me and says I've developed a PBBG...I can assess thier skill set pretty quickly. If someone says they've done a Flash game...well...I know a lot of easy ways to throw a flash game together.

Is it important to you that Flash games be excluded from PBBGs?

5 Interesting Sites for the Creativity Seeker

Innovative

This site takes my breath away. Creative, beautiful and entertaining. It's not about a whole lot but still shows the power of what you can do with the web.

Expirements in Javascript

Click on one of the links, this guy has a bunch of experiments in Javascript and flash. Interesting stuff to play with and see just what you can do with Javascript.

Photoshop Tutorial Playground

Whenever I visit this site I always find something new to try and play with on my own. It's a list of links to tutorials on photoshop and image manipulations, but let yourself wander through the sites, they are all pretty good.

DIY Wonders

Wonderful things you can create all by yourself with a little ingenuity and creativity. Some technical related, some just fun to do. Again, I never fail to find something to try after reading this page.

I have an "Inspirational" and "Interesting" folder link, these sites sit in there. From time to time I bring up the folder and go visiting. Especially when I'm bored.

Where do you visit to kill time? (Excluding game sites, we all know how to find those.)

Setting up Development Environments

I'm all about instant gratification. I get this kewl idea for a game. I wanna get started on coding. I wanna see something up and running in an hour. I want to have a functioning prototype in the following day or two. I wanna do it and I wanna see results NOW!

*sigh* The details always seem to get in the way. If you are a game developer and have done more than two games, you know exactly what I'm talking about. Before I can get one lick of code written I have to setup a "playground" for myself. Generally this involves the following:

• Create a web directory (root, images, js, include folders)
• Create a database
• Ensure connection to the database
• Create a login page
• Create a registration page
• Create a shell template

Maybe it's just me, but I find all this stuff ... boring. I'm interested in alternatives that folks might have, but this is what I do right now.

I have a copy of XAMP (Apache, PHP, mySQL for windows). It all exists in one directory.

In the root directory I have a template folder which has a login, register and basic template. I copy this folder when ever I start a new idea.

In the mySQL folder, there is a template database (user tables mostly), I copy this folder to create the database folders. This creates my databases.

I then edit the config file to connect to the correct database, this usually gets me off and running.

This usually takes me about 30 min to do, which I'm really kewl with as it gets me off to the races quicker. But I sure wish it took me 30 seconds. *grin*

So, to all my developers out there, how do you setup your development environment and how long does it take you?

5 Steps to Good Virus Protection

"You're protected from viruses, right?" I ask my friend.

I watch the always dependable reaction. Eye shift, foot shuffle, then a wincing "I think...I mean I have Norton on my desktop". Usually followed by a sheepish grin.

My friends, like most average users, know that they should have virus protection, but it's ... difficult to make sure you have the right thing installed. In hopes of making it easy here are some quick tips.

My rule about Anti-virus software: It should be invisible, until I have a problem. If this ain't true then I've got the wrong software package.

Step 1:
AVG.com - Go to the site, click on home version, click on trial and download it. It expires in 30 days, but we will discuss this later. DO NOT INSTALL YET.

Step 2:
Remove any anti-virus software that you might already have installed. Click the Start button, Goto to Control Panel, Add Remove Programs, Uninstall your old anti-virus.

This is an important step as multiple anti-viruses will slow your machine as well as cause one another to fail.

Step 3:
Now install AVG. Just follow the prompts, its relatively painless. You DO NOT have to INSTALL any toolbars. (Unless you want them)

Step 4:
When your done installing, click on the AVG icon in your start tray. (The area down by the time and date).

• Click on Scans
• Create a scheduled scan
• It should scan once a week
• It should scan all drives
• Let it start at 12:00 Noon
• If it misses a scan, start a new scan the next time the machine boots.

Step 5:
Whenever you login, check for the AVG icon in your start tray. If you don't see it you have a problem.

That's it! It's not difficult! The only time I see AVG is when I have a virus. It automatically checks all files I save, anything I download and it even checks web links before I click them. It's cool, in a geeky sorta way.

Trial Period
Oddly enough, my 30 day trial expired, but this means that when a virus is detected, I get an offer to buy the product but it still cleans and scans my machine. I encourage you to upgrade and buy the full package. Matter of fact, I'm going to buy the software today.

Updating
At times you might get a popup/message that it's time to update your virus protection. Do it, it will take 15 min and run in the background. You should be aware that AVG will daily download minor updates for itself. However this will happen without you being aware of it. The bigger updates typically mean something special happened. These are the ones you will receive an alert on.

Other Antivirus Packages
There are a number of anti-virus packages out there. All are pretty good, so feel free to try them. Just try them one at a time. I recommend AVG as it's NOT well known. Which means hackers are not specifically targeting their system. It's a small advantage, but "life's a game of inches."

Malware - Antivirus Impersonators
This sounds counter intuitive, but be very careful of any popup message saying you have a virus There are a number of hacks that impersonate your anti-virus software. They look very close to the real thing! If your suspicious of something, just cancel out and click on your AVG icon (in the start tray). It will let you know if there is a problem.

If you get one of these malware viruses that LOOK like a anti-virus software, seek a professional. These viruses tend to get out of hand very quickly!!!

Finally, I would challenge my friend Mr. Clark over at Clark Thought Leadership to write his own blog entry on this topic. He specializes in IT and PC Security.

So tell me what Anti-Virus do you use, and does it work for you?

What is a Server?

As a Business Analyst, part of my job is translating technical terms to non-technical folks. The trick is to do it as simply as possible.

So, What is a Server?

A server is a computer that sends and receives data to and from other machines.

A server can send and receive a lot of different types of data. But in some cases the server only handles a certain type of data. Some examples:

• Web Server - Sends web pages
• Media Server - Sends images, videos and mpgs
• Print Server - Sends print jobs
• File Server - Sends any type of file

And the list goes on. Now sometimes one physical computer will have multiple types of servers on it. This is cost effective and a lot of businesses do it. Microsoft even markets a product around it. The"Small Business Server" product does pretty much all of the above.

The most familiar server you will run into is a web server, you will need one of these to have a website. While it's the most familiar, I believe the most popular server is a file server.

What technical topics would you like to see covered next?

What Your Signature is Telling Me

Take a blank piece of unlined paper.

Now quickly sign your full name as you would if you had to sign a check.

Now write a sentence in cursive. Any sentence will do but for you anal retentive folks try this one: "Today is going to be a great day.".

OK...go do it...really, this is going to be interesting.

Did you do it?

Really?

OK, look at your two writings:

What direction are your letters sloping?

• Backward - You are a reserved person, the more slanted the more reserved you are. Typically you will hide your feelings rather than express yourself. This is because you wish to be true to yourself.
  
• Forward - You have no problems communicating and often times will go out of the way to do so.
  
• Straight Up and Down - You tend to be removed from the world, aloft.
  

How large do you write?

• Large - Either you are very outgoing, or you tend to hide yourself behind big bold actions.
  
• Small - Small letters reflect a thinking mind
• Normal - Well, you are normal

Note: If the writing looks "delicate" your likely not to communicate well, but are a deep thinker.

How much space is between the letters of your words?

• Very close together - You are a social butterfly, you love interactions and may even be the life of the party.
• Normal Spacing - You are shy, don't create a lot of connections maybe due to high moral values.
• Further apart - You act swiftly and decisively, sometimes without thinking

How much space is between the words?

• A lot - You tend to resist the influence of outside voices and your own emotions. You like to come to a logic conclusion when searching for an answer.
  
• Small Spaces - You like to be in the midst of a conversation, one may consider you a busy body.
• No spaces - Your quick like fire, easily moved,swift response, almost impatient with the self confident and ego to go with it. You might find yourself taking over conversations quite easily.
  

Does what you wrote tilt?

• Tilting Up - Your an optimistic person
• Tilting Down - Your a pessimistic person
• No Tilt - Your pretty balanced
  

In General

Looking at the middle section of your writing, this would be the space where most of the word exists. The size of this area indicates your self image. The larger this area is in relation to the entire word the greater your self image. This is especially true if the area is very small.

In general the further your letters go from the middle area the more ambitious and out spoken you are. You can especially see this when looking at the letters Y, P, G, F, S.

A person who continually "flourishes" their F, G, or S can be said to be an especially outgoing and emotional person.

Look for how high the tops of your letters go, those that require you to go into the capitalization part of a letter. The higher the letters go the more this person focuses on the realities of life. This could be monetary, power or friendship. The higher the flourish the more drawn this person is to those things.

Look for how low the person goes under. Every sentence has a base line which can be drawn under it. The depth of the letters under this line, such as the bottom of the letter g, show how deeply the person dwells on their inner thoughts. This would indicate an avid reader or knowledge gather. Someone who has no problems thinking and being by themselves with nothing in particular to do. Pen strokes under the line also signify a person in touch with thier natual instincts. The more strokes the more instinctual this person may be.

Most interesting, someone who goes deep under the line and has large fat loops has an active and eager sexual drive. For those single fella's out there, ask the lady to sign her name as well as her number next time.

For those whose writing shows few flourishes, big swoops, broad strokes, dashes, etc. This person is usually one who comes to a task with much concentration. They will tackle a problem very directly and, in almost a bull dog fashion, not move on until the problem is solved.

Seeing a lot of carefully dotted i's and crossed t's? This indicates that you are a solid person. Once a path, decision or selection is made. More often than not, you will not have your mind changed. This is especially true if the dot above you i's are exactly in the right place.

Now, I hope that none of you exhibit this, but if you do...ummm, I wish you well. Pull back from your writing...try to draw a line under your sentence, if the line ends up very crooked and the crook or joint in the line is in the middle of a word. Odds are you have some mental problems. (or your drunk, try again later) Crooked lines and flourishes the counteract one another are typically found in the more deranged folks in our society.


What's the difference in your Signature and your Sentence?

This is one of the more gray areas of handwriting analysis. One theory is that your signature represents your self image and your sentenace represents your true image.

My personal theory is that your full signature (last name included) reflects your true personality. Your Sentence reflects how you feel at that particular moment.

I've done this on myself a number of times and I get different results in my Sentenance all the time and usually it is because of different moods that I am in at that particular moment. My signature is pretty stable.

In Conclusion
The study of handwriting is called "Graphology". I am no expert on this, just something I've learned and enjoy using over the years.

All of the above is theory and conjecture and may not necessary represent you.
