Nairaland moderators can edit posts?
Thats very bad

Hi guys.
Anybody making progress on the challenge? I just solved the first question

You guys can test your programming skills by trying the ReadyForZero Challenge. This is the link:
www.readyforzero.com/challenge.
I haven't started yet cos I still have some left over work from the office,

For IE 8 and 9 its even easier. Just press the developer key (F12), click Tools in the menu bar and if you know what you are doing you'd know the next step.

No add ons.

Honestly it took me a while but I got it myself

Arik air is the worst airline in Nigeria. Unless you have no other option and you have time to waste, its better to trek. You'll probably reach your destination before their aircraft takes off.

The worst comments are coming from those who have never been in Katsina. Na wa for all of you o.

Well, i live in katsina. I was posted here in November last year. There was some violence here during the election period but that was related to the killing of a youth by a trigger happy policeman but the police and the army acted in time to prevent a major disaster. There was post-election violence in other Katsina cities too like Funtua, Daura and the rest but in the state capital there wasn't and the violence wasn't a massacre like in Kaduna and Kano.
I think you can consider taking the offer as Katsina (historically) isnt known for violence. Just be prayerful (like I am).
I'm still looking to leave here sha because I'm in the north but violence is very low in Katsina state capital.

Hi guys,

I don't mean to infringe on this thread, but I just wanted to direct beginners who want to learn Java to some very good and FREE materials for learning:

Stanford University (one of the top universities in the U.S) actually provides a full beginners course for Java: "Introduction to Computer Science |
Programming Methodology" that can be taken online. (Please note: this will NOT count towards you obtaining any credit/actual qualification from Stanford, but serves only are free training material)

You can download/view all the material for free. There are about 28 lectures in the course each about 45-50 minutes each, videos of the lectures can be found on Youtube. Other materials include the syllabus, handouts, assignments, and even an exam paper. you can also download all the software you need from their site. Check out the link below (hope this helps):

http://see.stanford.edu/see/courseinfo.aspx?coll=824a47e1-135f-4508-a5aa-866adcae1111


(they also have a few other free online courses if anyone is interested - just have a look around their site)

Same as MIT with their open courseware.
Check www.ocw.mit.edu

I got transferred to work in katsina. I went to the Skye bank branch in katsina to request for my transaction alerts to be sent to a new email address. I was told that I had to write a letter which they will scan and forward to my branch and then wait for my branch not only to reply but also effect the change.
All our banks claim to be computerised and I still have to write a letter before I can change my email address in their database. By the way, the change hasn't been effected 6 months later.
How are banks supposed to be able to handle the complexity of such a venture when to change my email in their database is still manual?

You can force a horse to a river but can't force it to drink. As an economist, I believe in the invisible hands that push demand and supply.

I tried on torch which is OS 6 and it works, I tried on 9700 OS 5n doesn't work, I tried on 9000 which is also a bold OS 5 and it works.
The markup of the pages passed w3 xhtml validation so I'm sure its not because of a mistake in my markup that might be confusing the browser.
The javascript I used is very minimal, just to color alternate rows of a table however I will cross check to see if the phones that failed didn't have javascriopt turned on. That's the only thing I can think of now.
Thanks pcguru.

Hi guys, I'm testing my website and i noticed something weird. Some guys have complained that my website is blank when they load it from their blackberry phone browser. Mine is "Curve 2" OS 4.6 and it loads right. It also works right on "Curve 2" OS 5. A tour OS 5 reported blank page on BB browser, same with "curve 3" with OS 5.

My website DOCTYPE is XHTML 1.0 Strict. Does anybody know why it might be blanking on some BB phones? I have just 10MB bandwidth thats why I don't want to post the web address. The problem is that the site was built with django and there is no Nigerian webhost that can host django applications. Getting a dollar debit/credit card is a problem but i'm not focussing on the yet since its still in development.

Hello!. Pls i want to be connected online 24hrs for free

Cheap skate. Buy a modem. You won't regret it(research about the best network in your locality first o).

Note that the previous code is "a little buggy" because it doesn't address all whitespace so if you click in the first name field and you press the space bar, the alert won't trigger even though the field is empty. To come against this problem, you will have to use regular expressions (google it) to capture all whitespace and integrate that into your code. Hope I haven't confused you

@lolade:
obviously you did not learn anything from from naija swag's earlier solution cos you are making the same mistakes. First, you always have to put the id attribute in your HTML so that you can have access to that element through document.getElementById(). Note that there is also getElementByTag() which will select all tags passed into the function. Google javascript's DOM(document object model).

With this line: <SCRIPT language="JavaScript">, the script can never work. Next time use "javascript" not in camel case like you did hence <SCRIPT language="javascript">

my checkFirstName function would look like this:
function checkFirstName()

{
if (document.getElementById("firstname".value.length == 0)
{
alert("Please Enter Your First Name";
}

}
(no long thing). The function is assuming that the field with name "txtfirstname" has id="firstname".

Dont forget to read(or google javascript DOM) and also learn about XHTML (cos your markup, isnt there yet). I havent tested the javascript but im sure it wont throw an error

@mikky: which of the options did you pick?

Hi. Im 95% through with working with a django news web application. As usual, the site is not very pretty. I'm ready to pay a very good web desginer (CSS guy with a very good design eye) to redesign the site. I will provide the markup (HTML and CSS) of the site and the coder is expected to edit (or change completely) the CSS file to provide a newer, professional looking (minimalist) site.
Of course I will require a portfolio or links to websites done by the person.
Thanks guys.

Actually a friend went for through their recruitment process and then got a text an SMS asking him to come for her appointment letter and N2,000. The money part is what is ringing alarm sirens

Hi guys.
Any information about Adkons Nig Ltd will be greatly appreciated. Thanks

well, you asked for it. Or didn't you? If you don't like it, ignore it. Is that too hard?
Me I was just wondering how you can secure data without securing the connection. If you don't secure the connection, you can have a middle-man attack where the attacker sends data and intercepts it before it gets to the receiver. By doing this, he can use clever algorithms to decode whatever encryption might have been used. Anyway, you can just ignore my comments. Anyway, sorry for seemingly picking on you; I won't do it again

meanwhile, your PayXress is 'strange'. Your description of the product is for that of a very unsecure product. Are you sure there was any research into this your method?

what is the VIN and the location of the car?

whats the VIN number and the location of the car?
