Practice for Programming Competitions using an online judge

Programming Challenges contains over 100 programming challenges found in multiple programming books that will provide you with an excellent resource for practicing for a programming competition or for simply polishing your skills.

The premise is simple. After signing up you simply choose a problem, read the description that contains sample input and ouput, and then submit it to an online judge. You then can submit your response in either C++, Java, or Pascal.

Upon submitting your answer, within seconds you should receive one of the following responses: Correct, Incorrect, Presentation Error, or Time Exceeded. You can retry the problem multiple times if you didn’t answer it correctly or go on to view statistics based on your submissions and of other users.

Practice makes you a better programmer

So if you are looking to polish your skills or practice for a competition this website is a good place to start. It keeps track of all the problems you have solved and yet have to solve and the problems can be solved by anyone with any type of programming background. Novice to experts are welcome.

Do you have AIM? Did you know you could send and receive free text messages? Yes, you heard me right. Free. Gratis. For nada. Sounds good doesn’t it?

Sending free text messages with AIM

First of all, you need an AIM account. Then simply add a contact beginning with +1 followed by their full number including area code. In order for people to send you text messages, you must send them a message, and have them save the incoming number to contact you in the future.

That’s it. You can send a free text message as long as the receiver’s carrier allows you to. Sometimes the receiver must accept incoming messages but its a one time procedure. The only down side is you must be connected in order to receive messages. If you aren’t, you’ll miss the text entirely.

Can I use other clients other than AIM? What about my phone?

Sure why not? Digsby and Adium allow you to text friends. It’s simply a contact according to AIM. Last time I checked, online client imo.im also allowed you to send and receive these messages, while Meebo didn’t. Maybe it’s changed since then?

Many phones support AIM. So as long as you have access to AIM, you can send/receive text messages. If you have access to AIM on your phone, you can avoid a texting plan. Neat isn’t it?

I was user of AIM with my iPod touch but lately all the crashing and lagging made me make the switch to Beejive. So far? I’m loving it.

Beejive is worth the $9.99

Sure, $9.99 does sound like a lot. Considering I don’t have a texting plan, I didn’t mind forking over the money. I was skeptical at first but it comes with a great variety of features.

• Connect to Facebook, MySpace, AIM, Yahoo, Hotmail, and more…
• Desktopish type of application – Comes will all types of features you’d expect out of a desktop application
• Apply themes to conversations and the application itself
• Push notifications alerting you of new messages
• No lag and minimal crashing
• Easy to switch over to conversations and preview last message your buddy sent
• Overall, feels slick and sexy. Even the icon looks good on my home bar
• Vertical and Horizontal typing. Your current typing in progress is displayed on a transparent bubble which optimizes your chatting viewing area.

So if you are looking for another instant messaging application on the iPhone/iPod Touch, try out Beejive. So far its been the best looking and working instant messaging application I’ve used.

PhotoXpress is another great stop for those looking for free stock photography. They currently offer over 410k photos that are available for download once you register for free.

So is PhotoXpress really free?

Yes, the only catch is you can only download one photo per day. Want to increase it? Then fill out your profile and you can download an additional 5 per day. If you want even more, connect your account with Facebook and it will grant you an additional 4 per day.

I’ll be trying it out as it seems an excellent resource as the images are great for using within posts, and layouts as well.

Getting ready to edit your template to make a website

In this part of our series you will start editing your template to make your website. Don’t worry, I’ll guide you every step of the way so you don’t get lost.

What do you need?

1. The BigSpaceLove template found on Free-CSS-Templates
2. A browser to open your website. (e.g. Internet Explorer, Firefox…)
3. A text editor to edit your website. Preferably one that supports syntax highlighting. Programmer’s Notepad is free and is what I’ll be using.

Start editing the template

Open up index.html using your text editor. If you remember the basic structure of a website we taught you can notice that it is the same way the html file is structured.

• The header contains “Website Title” and “Subheader, website description H2″ in this case
• The body is separated into a left section containing the content the and a right section containing the menu.
• The footer contains information about the person who created the template.

You will notice these sections are denoted with the following tag in the HTML document:

The <div> </div> tag

You can think of the div tag as a section within your HTML document. They will usually be named after the sections described above.

Making and viewing changes to your website

To make a change, simply save the index.html file at any time. Then open it using any browser. Once the page is open, you can refresh it thereafter whenever you make a change to the html file.

Changing the title of your website

Let’s change the title of our website. Currently it says Big Space. Look for the following code in the html file.

It should be enclosed within the section. This section is used for placing information about the website such as meta tags, links to the css stylesheet, and the title of the site.

Let’s change the title to whatever you want. I’ll name it the following:

Now view the changes you have made using the steps I provided earlier. See what happened? The title of our website changed, this isn’t visible on the page itself but in your browser.

Editing the Header Section

Now let’s go ahead and change the “Website Title”. Look for the following.

I’ll be changing it to the following.

If you noticed, I change “#” to “index.html” above. “Let’s Talk Binary!” is encapsulated with the <a> </a> tag making it a link. Whenever you click on it, it will take you to the index.html page which is the current page your on.
It is also encapsulated with the <h1> </h1> tags, making it a header.

The <a> <h1> tag

The <a> seen is used to create a link to another document with the source being “index.html” in our case.

The <h1> tag defines headings. The values range from 1 to 6. 1 being the largest.

Now save and view changes. Isn’t this easier than you thought?
