Review Of HP, Sony, And Compaq Laptops

Review Of HP, Sony, And Compaq Laptops

So do you prefer to call them laptops or do you prefer to call them notebooks. I am partial to notebooks as I never keep them on top of my lap. Jokes apart, purchasing a new notebook computer is really tough.If you were to read the ads then each computer sounds better than the cat's whiskers. But when you look close, they all look similar. At least the similarly priced ones tend to be similar. So, is there really a difference between one laptop and another? Or should I say one notebook and another?To answer this very question, I am going to look at three popular computers that are currently on sale and compare them. The read can then take this to be the starting point and evaluate many other options to find the one that works best for them.First of all, let us consider the HP Pavilion DV6426US, a machine that I powered by the Intel Core Duo Processor T2450. This multithreaded architecture based micro processor is well optimized for multi-tasking based performance. The fact that this notebook comes installed with 1 GB RAM should help run many of the contemporary popular applications at a good speed. It has a 160 GB Hard Drive which is nothing spectacular, but should do the trick in most cases. And the bundled operating system is the Microsoft Vista Premium. And I really like notebooks that come with an integrated WebCam. This HP laptop sure has one of those. In the absence of such a webcam, attempting Video IM becomes a serious pain.Second let us consider the Sony VAIO VGN-FZ140E/B. This laptop too is powered by a Duo Processor, in this case the Intel Core 2 Duo Processor T7100. It beats the HP one in terms of RAM, as it comes with 2 GB RAM. Its hard disk is bigger at 200 GB. So, if Freud was right and size does matter then, well, this one has the bigger Hard Drive. The duo-core multithreading micro processor will deliver performance similar to the HP machine. This laptop comes with Microsoft Vista Home Premium.Finally let us look at the Compaq Presario F572US. Like both the previous machines, this one too has a 15.4" screen. Though it has a dual-core micro processor, the Compaq uses the AMD Athlon 64 Processor TK-53 and not an Intel based processor like the other two I wrote about. Also it has 1 GB RAM like the HP machine. Where I think it scores lower is in its hard disk capacity, a mere 80 GB. It also comes with the Microsoft Vista Premium.All in all, the machines have pros and cons. I have not listed prices here, as they would change faster than I could type them out. But, make sure to look at the prices too.

5 Gadgets That A Good Spy Cant Live Without

5 Gadgets That A Good Spy Cant Live Without

Whether you are an amateur or a professional, gadgets play an essential role in the life of a spy. Although there are some tools and gadgets which are only designed for specific situations that you may encounter as a spy, there are other gadgets which can be useful to you every single day. If you are a spy and dont have these five gadgets, you are missing some valuable tools from your arsenal:1) Portable Bug Detector-As a spy, you are responsible for not only obtaining information, but also keeping privileged information completely secret. Whether you are concerned about a phone, room or car bug, a portable bug detector can provide you with the security you need. Portable bug detectors are extremely easy to operate, and allow you to quickly decide whether or not it is safe to divulge confidential information in your current environment. Best of all, portable bug detectors are easy to conceal, which means that you can take one everywhere you go. 2) Room Bug-Although you need a portable bug detector to protect yourself, the primary job of a spy is surveillance. In order to do this, you need to know what other people are talking about. The best way to accomplish this is with a room bug. You can place a room bug in any environment, and then listen to the conversation from a secure location. Because they can only be picked up by radio scanners, Ultra High Frequency (UHF) room bugs are your best option.3) Binoculars-Since a lot of your surveillance will take place from a distance, it is important to have a pair of binoculars with you. Having a quality pair of binoculars can mean the difference between whether or not you are successfully able to identify someone.4) Audio and Video Recorder-This is the gadget that the general population almost always associates with spies. An audio and video recorder will allow you to obtain and preserve valuable information and evidence.5) Notepad-This may seem overly obvious, but many spies neglect to carry a notepad with them. Whether its writing down a license plate number or a description of a suspicious person, a notepad is arguably the most important tool a spy can carry.

Php - A First Look

PHP: Hypertext Processor is a server-side web programming language that blends seamlessly with HTML. PHP can run on both Unix and Windows servers, which makes it more accessible than its Windows counterpart, Active Server Pages (ASP). Most full-service web design firms will have at least one PHP guru.PHP uses are widespread, and can include any kind of server functionality that takes users input and displays or manipulates the input. Some pertinent examples of such work are message boards, auction sites, shopping carts, and more. This synopsis is meant to serve only as a gateway to other works; although the main goal is to give a reader enough information so they can make educated decisions about what their web developer should do. For those looking to get into PHP, there are many free tutorials and primers out there:http://www.4webhelp.net/tutorials/php/basics.php, is a pertinent examplePHP generally uses the mySQL database system. MySQL is a server-side system that is included on many Unix, and some Windows servers.Once a user knows the basics of PHP and its capacities, he can work with plenty of open-source scripts. Without having to actually build a script from scratch, one can get a fully functional website with a custom design (assuming the designer has HTML/graphics knowledge). Two of the most popular open-source (free) scripts for PHP/mySQL are PHPBB and osCommerce. PHPBB is forum software that is fairly common. It has all the main features of a message board and can have mods (modules) added for more features. OsCommerce is a shopping cart script that has support for many payment gateways, including some free ones like Paypal. The great thing about scripts like these is that they have a full community of developers both beginners and professionals that are there to help with installation and modification.However, if a user doesnt feel that hes ready to take the plunge and work with PHP code, most web design firms are more than willing to work with open-source scripts. Others even have their own pre-made, or can work from scratch for an upgraded fee. Sometimes, an open source script simply wont suffice because a user needs something tailored to his needs. Larger-scale online business and e-treps require capabilities that may be out of the reach of osCommerce.To conclude, PHP is a server-side scripting language that offers widespread capabilities for web developers looking to interact with their viewers. It may take years to master a technology like this, but there are plenty of great deals out there for pre-made scripts or from-scratch technologies. This story served as an introduction to PHP, later articles will go into further detail.
