The NETTUTS.com site has a new video tutorialshowing how to create a basic login by combining PHP and jQuery.
In today's video tutorial, we'll be building a login system with PHP and MYSQL. Many, many features will be covered; including MySqli, Prepared Statements, jQuery, Classes, Sessions, Cookies, etc. I bit off more than I could choose for today's screencast. So, I'll be creating a Part 2 in the next couple of weeks in order to improve our system even further.
You can grab the source here, but you'll need to check out the post for the video itelf.

Dan Wellerman has written up a tutorial for NETTUTS.com about making a jQuery and PHP-powered tag cloud out of the tagging already a part of your site.
Aside from the actual links themselves, which give people an idea of the subjects that your site covers, they can also show how popular the different subjects are. Another great thing about tag-clouds is that they can be used to describe the frequency of anything; you can link to articles, blog posts, images, video, or anything else that you have in abundance on your site.
The javascript makes an Ajax call back to a PHP script waiting in the background (that pulls the tags out of their example database). It puts them into a JSON format and pushes them back out to the script, though they should have gone with json_encode instead of their own partial soltuon.
The jQuery then parses the JSON message back out and drops it into CSS styled divs already in the page. As always, the source in available for download.

The Consumer Electronics Show (CES) is increasingly appearing to be the place to be in 2010 for Apple vendors. The tradeshow announced the iLounge, an 18,000-square foot area for Apple gadget sellers. A gauge of the swiftness of the shift from Macworld to CES could be seen in that the Apple-centric venue at CES initially was to be just 4,000-square feet. “In fact, the original space allocated for the pavillion sold out in less that one week - a CES show record,” AFP quoted CEA vice president Karen Chupka. The focus on CES by the Apple community followed Cupertino’s decision in December to make Macworld 2009 the last year it appeared. Soon after, word leaked out that Apple was headed to the CES to compete head-to-head with Microsoft and other rivals.

Acer 10 Aspire One now with Linux
The Acer 10 Aspire One launched last week but it seems that one vital ingredient was missing – choice of operating system. Fortunately, Acer 10 Aspire One will now come with Linux as well as Windows XP. The move has been made in a response to user demand. Last week’s announcement made Linux conspicious by its absense, especially considering that Acer made such a deal out of it’s own interface with the launch of the Acer Aspire One 8.9-inch version.
When Acer launched its first successful netbook, the cunningly named Aspire One, it shipped with Linpus Linux with an interface especially designed for Acer. It meant that even those new to mobile computing could make the most of the 8.9-inch netbook as it came with everything you needed, including word processing and host of other applications.
It also came with its own novel email client that allowed you to manage all your separate email accounts from within one application. This works really well and it seems you’ll now be able to take up the option with when the new 10-inch model launches next month.
The Acer 10 Aspire One will have the same spec and be equipped with an Intel Atom N270 processor, 1024MB of memory and 160 GB internal hard drive regardless of whether you opt for the Windows XP or Linux version. Weighing 1.18kg, the Acer Aspire One comes with a 10.1-inch LED screen (1024 x 600 pixels) that comes with a built-in Acer webcam above the panel.
Connectivity includes Bluetooth, 802.11g Wi-Fi, as well as Ethernet for fixed connections. There is even Acer’s Signal Up technology for as strong a signal as possible. The Acer Aspire One has the option to be fitted with 3G or WiMAX but there are no details yet of any telcos choosing to take this option on.It will come in four high-gloss colour options including white, blue, red and black.
The Acer 10 Aspire One will cost £299 (inc. VAT) when it ships towards the end of February. In the meantime, if you want to check out the current Acer Aspire One offerings, click here.

Smashing Magazine: 10 Steps To Protect The Admin Area In WordPress
As all of the WordPress users out there know, the "admin" section of the installations is one of the most important areas of your site. That being said, it should also be one of the most well protected parts. This new article from Smashing Magazine has ten tips that you can use to help protect you and your blog from prying eyes.
The administration area of a Web application is a favorite target of hackers and thus particularly well protected. The same goes for WordPress: when creating a blog, the system creates an administrative user with a perfectly secure password and blocks public access to the settings area with a log-in page. This is the cornerstone of its protection. Let's dig deeper!
Here's their ten tips:
- Rename and Upload the wordpress Folder
- Extend the file wp-config.php
- Move the wp-config.php file
- Protect the wp-config.php file
- Delete the admin User Account
- Choose strong passwords
- Protect the wp-admin Directory
- Suppress Error Feedback on the Log-In Page
- Restrict Erroneous Log-In Attempts
- Keep Software Up to Date
PHP-GTK Community Site: World map of PHP-GTK developers
The PHP-GTK Community site has launched a new service to help PHP-GTKers out there find out other developers that might be in their area - a world map (based on Google maps) of other PHP-GTK developers around the world.
I reviewed the coordinates given by existing members and noticed a good number had visibly inverted latitude and longitude; so I inverted them again to place them where it appeared to make more sense (are there really PHP-GTK devs in the middle of the pacific, or near the South pole ?). So you may want to double-check your coordinates to make sure the values are correct, because it's likely I've not found every error.
He's also asking for the Brasil PHP-GTK community to include their information in the map as well as a request for anyone out there that might want to make a "prettier" icon for showing the developers on the map.

Samsung, already pleased with itself for introducing DDR, DDR2 and DDR3 RAM, said it has created the first-ever 4-gigabit (1 GB) SDRAM chip. Throw eight of these on a laptop memory stick and you’ve got twice the RAM that is currently available. It’s also more efficient than regular DDR3 memory thanks to a 50 nanometer manufacturing process, with an estimated 20 percent power savings of 2-gigabit sticks. Transfer speeds reach 1.6 gigabits per second. Samsung doesn’t say when these chips will be commercially available, but the International Data Corporation estimates that “over 2 gB” DDR3 RAM will comprise 3 percent of the market this year and more than half the market by 2012.

These features facilitate in optimizing data throughput, data resource productivity and data tape longevity. Data is considered as one of the most important and valuable asset of the company. Archived data occupies most of the storage environment’s overall capacity therefore, it is important that cost effective, efficient, reliable, secure data retrieval and data backup systems must be implemented. Data storage companies must secure and protect the data irrespective of its location and during transit so that they can comply with the rigorous service level agreements (SLA) and legislative mandates. Records that are unrecoverable or lost no matter if it is measured in expense, public image or time are very costly for the organizations. Selecting the most ideal and suitable medium for data preservation and validation of document authenticity is very critical.
