Bạn muốn một cái máy tính bảng? Hãy nghĩ lại đi.

Máy tính bảng thời gian gần đây đã trở thành một trong những chủ đề bàn tán thú vị và chiếm một phần rất lớn nội dung thế giới online lẫn offline của chúng ta. Thậm chí có một số website chỉ phục vụ cho mỗi nội dung là máy tính bảng, thậm chí là một nhãn hiệu máy tính bảng.

Nếu là người hay online, hẳn bạn đã ghiền nó, nếu bạn mê game, mê cái mới, và mê cái cảm ứng chấm quẹt, thêm lí do để ghiền. Vậy có nên mua máy tính bảng không, có nhiều lí do để nói uh và có nhiều lí do để không.

1. Máy tính bảng giúp giải trí tốt hơn.
Phần nào đúng. Nếu bạn là một người mê giải trí tầm thấp, không chuyên, thì mua một cái máy tính bảng là một lựa chọn không tồi, giải trí bao gồm những gì: đọc sách, xem phim, chơi game, nghe nhạc, đọc tin tức, chat chit, vẽ vời etc. Vì sao tôi nói là tầm thấp, vì một cái all-in-one không bao giờ sánh được với những thứ được-sinh-ra-để-làm-việc-đó. Một cái iPad không bao giờ nghe nhạc hay bằng cái Creative với tai nghe Auvana được, một cái Samsung Galaxy Tab không thể coi phim đẹp bằng một cái tivi HD, hay đơn giản hơn là một máy tính với màn hình chuẩn PureHD (1366×768). Còn đọc sách? Tôi khẳng định, và luôn luôn 100%, là đọc sách giấy bao giờ cũng thú vị hơn và tiếp thu tốt hơn, nó giúp bạn tập trung, chứ không như cái món all-in-one kia, đang làm việc này dễ bị mê hoặc bởi những cái khác, mà đa phần là game, chơi để giết thời gian, mà thời gian là tiền bạc. Bạn nói bạn có ebook, đọc tablet dễ hơn, nếu có một kho ebook, thì đọc trên cái laptop 7,8 tr cũng chả kém gì đọc trên máy tính bảng, mà pin lại còn lâu hơn. Thế đấy.

2. Máy tính bảng giúp làm việc tốt hơn?
Tôi không tin thế, công việc liên quan đến thế giới công nghệ luôn luôn đòi hỏi phải động tới cái bàn phím, mà cái bàn phím ảo thì ôi thôi, xài phát bực cả mình, huống chi gõ tiếng Việt cũng không phải đơn giản. Ví dụ như nền tảng Android, bạn dùng bàn phím Android, hay mạnh hơn là Better keyboard, hay mạnh hơn là SwiftKey. Chả có tiếng Việt. Viet IME thì giao diện không xuất chúng và tính năng không mượt như hai cái đã kể trên. Mua bàn phím gắn ngoài, tốn thêm mớ $ và đi đâu mang theo, thành ra y chang một cái laptop, mà giá tiền thì thôi rồi.
Nếu với những công việc chuyên ngành, như xây dựng chẳng hạn, thì vẽ chuột trên autocad cool hơn nhiều, cả photoshop, lướt web etc.. rất tiện. Tôi nhận thấy chẳng qua là người ta thấy lạ thì người ta thích, chứ thực ra dùng cho công việc cũng chẳng bao nhiêu.

3. Giá tiền.
Một cái máy tính bảng bây giờ, về VN, tính ra rẻ nhất có thể là khoảng 9tr, với giá đó thì sẽ làm được khối việc khác thay vì mua về một cái ngồi chơi game.

Trừ khi bạn có nhiều tiền, mà thôi bạn bất chấp tất cả để mua thì tôi chả còn gì để nói nữa!

Search Engine Optimization: Website Revenue Generator

Internet is used, to a great extent, for information search. People search for product, people, services, latest gadgets, car accessories and for lot of other things. For searching they use keywords which they stuff in the search engines. And search engines produce websites related to those keywords in the form of search results. Now, if your website is providing some good product or service, then it is necessary that your website is search engine optimized. Otherwise it may fail to be available to your prospective customers.In fact, search engine optimization is a technique which ensures that, if any Internet user is searching for your company, then it can become available to that user. For example, if you are making suspension bushes for cars and you are sure that these are the best bushes, then you must tell this to your customers. Now, if any Internet user search for the ‘best suspension bushes’ then your website must appear to him. If it is not search engine optimized then it is difficult. So it is suggested that you opt for some search engine optimization companies.

These companies make your website content-rich with appropriate number of keywords. In fact the first step in a search engine optimization technique is to choose keywords for each of your web pages. Keywords clearly describe the purpose and content of your site, and allow your site to show up as close to the first results page as possible. Also, a good position doesn’t depend only on your choice of keywords but also on how well do you position those keywords in your web page. Any SEO company make sure that you do your keywords selection right and position it on the proper place. Also, a search engine optimization company analyse demand and supply of keywords and then suggest you to use such and such keywords for such and such pages. This is how you can appear on the top of the search engine result pages. And this is the way to monetize your website.

How to Remove Spyware From Your PC

These days it may seem as though the short list of unavoidable perils ought to be expanded to include death, taxes, and spyware. But if you ever do get infected with some nasty piece of malware, all you need to get rid of it are the right free tools, some time, and a little know-how.

A couple of warnings first: Removing spyware is as much art as it is science. The rogues who create spyware make removing their malicious programs as difficult as they can. In addition, some types of spyware download and install additional components, often hiding pieces of code from Windows to make removal even harder. The instructions below will wipe out most forms of spyware, but your machine’s infestation may resist these measures. If so, you may have to consult a professional PC repair person. Or you can start afresh by reformatting your hard drive and then reloading Windows, your apps, and your data files (browse to our article “Windows Rejuvenated” for instructions).

Note too that if you perform certain removal steps improperly, your PC could become inoperable. Our instructions call out these danger spots, but if you don’t feel confident about performing them, ask for help from a knowledgeable friend or from the experts on a spyware-removal Web forum such as TomCoyote, Geeks to Go, or SpywareInfo.

Make Sure It’s an Infection

How do you know whether your PC has an active spyware infestation? Slower-than-normal performance is the most common symptom people report, but such behavior can also be due to any number of factors unrelated to spyware, such as running too many applications with too little system memory, having a full or very fragmented hard drive, or running buggy software that fails to free up the memory it uses after you close the application. Your first task is to determine whether you have a spyware-related problem or just a slow machine.

Download the latest versions of these tools:

• Microsoft’s Malicious Software Removal Tool. This program is updated monthly, so always download the latest version before you use it.
• Microsoft’s Windows Defender. Windows Vista has Defender built-in, but if you suspect that you have spyware on your PC, update the program so it can find the newest bad stuff.
• Avira Antivir PersonalEdition Classic, a free antivirus program–if you don’t already have up-to-date antivirus software.

Since some spyware applications prevent you from downloading these tools, or from visiting the Web sites that host them, download the programs to another PC that you know is free of spyware. Then copy the installers to a portable USB drive, and plug that drive into the machine you suspect is infected.

Start by running the Malicious Software Removal Tool. This program is designed to search for and destroy only a small fraction of malware, but the ones it finds are the most serious strains of spyware and virus you can get.

If that program doesn’t find anything, run the installer for Windows Defender (if it isn’t already installed on your PC) and make sure that the program downloads its updates. Then click the downward-pointing arrow to the right of the word ‘Scan’ at the top of the Defender window and choose Full Scan. If Defender finds malware, follow the on-screen instructions to delete the harmful files. This may require one or more reboots, because some spyware won’t let you uninstall it while Windows is running.

If Defender fails to find anything, or if it finds spyware that it can’t delete, it’s time for a full antivirus scan. If you’re using an antivirus program that is already loaded on your system, make sure that it’s updated. If you’re using AntiVir, run the installer, and then reboot. When AntiVir is running, you’ll see an icon in your system tray showing an open umbrella inside a red square. Right-click the icon and choose Start AntiVir. Click the Start Update link in AntiVir’s program window, and when the update is complete, click the Scanner tab, choose the Local Drives option in the lower pane, and press the <F3> key to begin scanning your hard drive. If it finds anything, AntiVir will pop up a dialog box. Select either Quarantine or Delete to remove the suspect files that it identifies.

Trojan Roaming Skype Network

Skype users are being hit with a Trojan that using the infected machine to reach out and infect the user’s friends and colleagues.Websense issued an alert on Thursday afternoon warning that the malicious code, known as both Warezov and Stration, is spreading through the Skype network again. An earlier version initially attacked late in February.

Dan Hubbard, a vice president of security research at Websense, said while the Trojan isn’t widely spread at this point, it is making its way across the network. While the code itself is not self-propagating, when it runs, a URL is sent to everyone in the user’s contact list. If their Skype program is running, a message will pop up, luring the user to click on a link, infecting them and continuing the malicious cycle.

The Trojan also opens a back door in the user’s computer, enabling a hacker to get into the machine and steal the user’s information or use the computer to send out spam or even a denial-of-service attack.

“Clicking on unsolicited messages in Skype is just not a good idea,” said Hubbard in an interview. “Users need to get the message.”

Skype is a free Voice over IP service, that enables users to record and playback audio.

The Websense advisory noted that Skype users receive a message that says “Check up this,” with a URL containing a hyperlink. When users click on the link, they are redirected to a site hosting a file named file_01.exe. Users are prompted to run the file. If the user runs the file, several other files are downloaded and run.

This is not an exploit taking advantage of a vulnerability in Skype, Websense noted.

A screen shot is available in the alert. Websense also offers tips on preventing this kind of attack.

Des utilisateurs de Skype sont frappés avec un Trojan qui à l’aide de la machine infectée pour atteindre dehors et pour infecter les amis et les collègues de l’utilisateur. Websense a publié une alerte sur jeudi l’avertissement d’après-midi que le code malveillant, connu sous le nom de Warezov et Stration, écarte par le réseau de Skype encore. Une version plus tôt au commencement attaquée tard en février. Dan Hubbard, un vice-président de recherche de sécurité chez Websense, dit alors que le Trojan n’est pas largement écarté en ce moment, lui fait sa manière à travers le réseau. Tandis que le code lui-même individu-ne propage pas, quand il fonctionne, un URL est envoyé à chacun dans la liste du contact de l’utilisateur. Si leur programme de Skype fonctionne, un message sautera vers le haut, leurrant l’utilisateur pour cliquer sur un lien, les infectant et continuant le cycle malveillant. Le Trojan ouvre également une porte arrière dans l’ordinateur de l’utilisateur, permettant à un intrus d’entrer dans la machine et de voler l’information de l’utilisateur ou d’utiliser l’ordinateur pour envoyer le Spam ou même une attaque de démenti-de-service. « Cliquer sur les messages non sollicités dans Skype est juste pas une bonne idée, » a dit Hubbard dans une entrevue. Les « utilisateurs doivent recevoir le message. » Skype est un service fini d’IP de voix libre, cela permet aux utilisateurs d’enregistrer et à l’acoustique de playback. Le bulletin de renseignements de Websense a noté que les utilisateurs de Skype reçoivent un message qui indique le « contrôle vers le haut de ceci, » avec un URL contenant un hyperlien. Quand les utilisateurs cliquent sur le lien, ils sont réorientés à un emplacement accueillant un dossier appelé file_01.exe. Des utilisateurs sont incités à courir le dossier. Si l’utilisateur court le dossier, plusieurs autres dossiers sont téléchargés et courent. Ce n’est pas une exploit tirant profit d’une vulnérabilité dans Skype, Websense remarquable. Un projectile d’écran est disponible dans l’alerte. Websense offre également des bouts sur empêcher ce genre d’attaque.
