Why are we still waiting for affordable laptops / netbooks / tablets for schools?

The mobile computing market changed forever a few years ago with the introduction of the netbook.  Finally a small, reasonably lightweight personal computer that could be carried by anybody.  Then the technology companies brought us a new breed of powerful ultraportables and finally tablets.  One thing to note though is that prices haven’t changed much, if at all, in the last few years.  Now you could say that this is probably down to the global economic downturn, problems facing technology manufacturing after the Japanese earthquake or one of a great many factors.  The fact remains though that around the computing market the prices of other devices such as high-definition televisions and digital cameras have continued to fall.

Now I’m a teacher by my first trade, and a tech author second.  I’ve been spending the last few years teaching Literacy and Numeracy to the long-term unemployed who need better skills and qualifications in order to be able to get back into the workplace, or to those people who are already employed and need qualifications to progress their careers.  I’m very interested then in the use of technology as an educational aid and, if you’re interested, you can read an essay I wrote on the subject for my teaching qualification here where I talked about some of the issues and barriers for the use of technology in the classroom, including the legal, physical and mental barriers that some people need to overcome.

It’s always with great interest then that I read news stories about how the latest technology is being used in classrooms.  In the last year I’ve seen schools, mostly in the US, giving iPads to each student and writing custom apps for the platform to help improve learning in class; one particularly interesting app was using the tablet’s accelerometer with a special app that helped the students simulate earthquakes.  I’ve also seen the use of videoconferencing to enable schools to share teachers with specific expertise and to bring in experts from the worlds of business, science and society.

Why is it then, six years after the launch of the One Laptop Per Child (OLPC) project that intended to create laptops for developing countries for only $99 that we don’t have schools rolling out laptops, netbooks or tablets to their students every year?  From the perspective of the technology companies this is an enormous market and opportunity; indeed Bloomberg are reporting today that Apple are bidding to sell 15 million iPads to schools in Turkey.

The single biggest barrier however is still price.  In order to make mobile devices that will appeal to the consumer and trample upon the competition, companies are still going for quality, brushed metals, high quality plastics and IPS panel screens.  What they’re not focusing on is the schools and colleges mass market where what’s required is ruggedness and affordability; after all these machines will be designed to only be used in educational establishments for their purposes.

Next week does see the launch of a new affordable Android tablet, the affectionately named (for anyone of a certain age in the UK anyway) AndyPad.  Starting at just £129 this is finally approaching the price levels that technology needs to be at to appeal to the huge volumes and limited budgets of schools worldwide, and of course some of the money can be saved elsewhere in providing cheaper eBooks instead of the traditional paper copies (while being more environmentally friendly into the bargain).

The fact remains though that back in 2005 when Nicholas Negroponte announced his plans to create a $99 educational laptop for the developing world the whole world got very excited.  Then companies like Microsoft decided that they wanted a piece of the action, muscled in and muddied the whole situation.  Now we don’t have any $99 laptops and there’s no immediate prospect that this will change.

It’s worth noting that some smaller companies have tried to release $99 tablets, certainly here in the UK, and all have so far been rubbish.  What must be needed then is the technological know-how and the manufacturing clout of a big name player.  Could Apple make a $99 iPad?  The company certainly makes enough money to subsidise such a device and it would sell in enormous volumes.  How economical that would be to a company with shareholders to pay though is up to Apple’s board to decide.

So I find it a pity that in what might turn out to be the ‘golden age’ of mobile computing that children are still being left out, especially the millions of them on low household incomes who still don’t have a computer at home.  It’s time I think for the technology companies to step up to this challenge and prove that $99 can still be achieved for the benefit of everyone.

Schedule Regular Disk Cleanup in Windows 7 and Improve Performance

All versions of Windows feature the Disk Cleanup utility that liberates space on your hard drive when it is bogged down with useless data. It is important to use the Disk Cleanup utility in Windows 7 regularly, at least on a weekly basis. Much of the data that needs to be cleared includes temporary internet files containing sensitive data such as passwords and credit card numbers. By leaving the data there, you are simply begging for viruses to snatch personal information and overall operating system performance is diminished as this data accumulates over time. The following examples and steps are from Windows 7 but will work on Vista, as the two versions have many similarities.

In the Start menu search box, enter “task scheduler” or “schedule tasks”, whichever works, and press enter. This opens the task scheduler dialog box.

windows task scheduler

Click on Action and in the dropdown menu, choose Create Basic Task. This opens the Create Basic Task Wizard. Give the task a memorable name and a description, keep it direct and simple and easy to recall.

drive cleanup task

At this point, if you have not done so already, decide how often you want the Disk Cleanup utility to run. You can choose Daily, Monthly, or one time. For the following example, daily is selected because the PC being used in this example runs a heavy load of internet traffic and overall use. If the PC is being used for home business purposes, it might be wise to schedule daily Disk Cleanup in order to ensure that data is not stolen by rogue malware. Also, set a system restore point before applying these changes.

task trigger

Press Next. Choose the start date. This is usually going to be “today” but you can set it to begin at a later date. Choose the start time. Keep in mind that you do not want this utility running while you are going to be using the computer for something that cannot be interrupted. Schedule it when you know there will be a break when the PC will not be in use.

task start date

Select Action and click “Start a program” then click Next.

start a program

Type cleanmgr.exe in the Program/script box, and /d driveletter in the add arguments box and click Next. Replace driveletter with the letter of the drive that you want to run the disk cleanup on.

disk-cleanup

This is the confirmation for the scheduled program, including name, description, and time interval settings for the trigger:

Any time interval can be selected, customized to the needs of the user. Windows 7 offers some versatile tools for customization and this is definitely one to take advantage of. Set the time for the scheduled Disk Cleanup for a time that you know the computer will be on an awake. The utility will not run when the PC is off.

Overall, since it is necessary to use the Disk Cleanup utility regularly, this gives the user the option to set it and forget about it. This is one for the geek in all of us.

Captcha Trader, Automatic Free Captcha Solving For JDownloader

The majority of file hosting websites make use of captchas when free account users or guests try to download files from their servers. For me, that’s more of a way to make the downloads less convenient to convince more users to upgrade to a premium account. Still, there is not much you can do if you need to download a file from the hosting server.

I already mentioned earlier today that I like to use the JDownloader software to download files from file hosting services. It is more convenient, especially since it saves the download queue so that downloads can be resumed at any time. Captchas on the other hand still need to be filled out. That’s a problem if you need to leave the computer for a longer period of time, or if you do not want the captchas to disturb you from other computer activities.

Ghacks reader KoalaBear suggested to use the plugin Captcha Trader for automatic captcha solving. The service is offered as a plugin for JDownloader, MiPony and a handful of other popular downloaders. It basically allows the user to either buy credits or solve captchas in advance so that captchas in JDownloader are resolved automatically by the plugin.

Here is how Captcha Trader works.

Visit the Captcha Trader website and create an account.Switch to the Plugins directory on the site and download the plugin for your software and operating system. I’m going to demonstrate how to add the plugin to JDownloader. Readme files are included that explain how the plugins are installed.Extract the folder and copy it to the \JDownloader\jd\captcha\methods\ folder.Edit captchatrader.properties with a text editor and add your username and password to the file.Restart JDownloader.

The plugin will not show up in JDownloader. It won’t work right away since you do not have any credits in the beginning. That is, unless you have bought credits on the site. 10000 credits on the site, good for at least 1000 solved captchas cost $6 Dollars.

Instead of paying, users can earn credits by solving captchas on the Captcha Trader website. A click on Earn Credits displays a captcha every 50 or so seconds. Solving the captcha correctly will award credits to the account.

automatic-captcha-solving

Users earn seven credits for text recognition captchas, and three for image recognition captchas. It costs ten credits to solve text captchas, and five credits to solve image recognition captchas.

It is furthermore possible to cash out at anytime. 10000 credits equate $1.

Once you got enough credits, captchas are automatically resolved in the software you use to download files from file hosts. The captcha should not pop up anymore which is great if you need to work full screen.

Gameplay Time Tracker, Track Time You Spend Playing Games

The Steam gaming platform has a feature that displays the time a game has been played by a user. You can look up your times and the time your friends have played a particular game. But the time tracking is limited to games on Steam, which limits the usability significantly as it excludes web browser games or games that are not integrated into Steam.

The free software Gameplay Time Tracker tops Steam’s time tracking capabilities by supporting pretty much any game that is playable on the PC. The program runs semi-automatically in the background. It monitors fullscreen applications on the system automatically assuming that all of them are games. A blacklist is provided to block certain fullscreen applications which are not games, or games that you do not want tracked, from being tracked by the application.

It is furthermore possible to add games to the whitelist, which can be handy to monitor games that are not automatically recognized as such by the Gameplay Time Tracker application. The third monitoring option supports browser-based applications. This works by adding websites to the browser-based applications list. Supported are the four major web browsers Microsoft Internet Explorer, Mozilla Firefox, Opera and Google Chrome.

Detected games are added to the database automatically. It is still up to the user to add information that are not filled out by the process. This may include a product description, notes, the game save folder or the release date of the game.

gameplay-time-tracker

Game statistics are displayed for all games in the My Games tab in the program interface. The tracker lists the program name, total and last run time as well as the total number of times the game has been started on the system.

Gameplay Statistics

The daily statistics tab confusingly displays statistics for the last 365 days of gaming. Here it is possible to display the full game run time per day, the daily game run count or controller specific statistics.

A right-click on the program icon in the taskbar displays a context menu with options to launch the main program window or to stop or restart the game monitoring.

Users who do not want their input devices monitored can disable this feature in the program options. There they can also disable the autostart entry.

Gameplay Time Tracker can be helpful for users who would like to monitor the time they play games. This can be useful to control the gaming to avoid spending to much time gaming.

Windows users can download the latest version of the game tracker from the developer website. The program is compatible with 32-bit and 64-bit editions of the Windows operating system. It was tested on a 64-bit edition of Windows 7.

Backup Data to a Virtual Hard Drive in Windows 7

Not many are aware that it is possible to create Virtual Hard Drive images in Windows 7. Backing up your data is important and this article will detail how to backup data to a Virtual Hard Drive (VHD) or hard drive partition. Creating the Drive is the first step, but the backup is the crucial point. It is best to use an external Hard Drive for backup, but this method can be easily as effective, as this data can be transferred to an external hard drive later. This is an especially useful feature for a network. All data from all computers and devices on a given network can be stored on a Windows 7 VHD. In this way, multiple computers can have their backup on one computer in the network and then all computers on the network can consolidate backups to a single external hard drive backup. This is useful for single PC users as well.

First, a quick review of creating a hard drive partition is demonstrated. To begin, go to Start > Right-click Computer > Manage. Or, enter computer into the run and search box and select Computer Management from the available options.

Click on Storage > Disk Management. Choose the drive that you want to partition. In this example, there is only one hard drive to choose. It is a 1TB hard drive with an NTFS files system and plenty of space to allow for a significant partition if necessary.

partition hard-drive

Here, the amount of shrink space entered is 100,000 MB, or 100 GB. This is a decent size for a VHD and it can be altered in the future. Click Shrink when done.

Select this unallocated space and right-click and choose New Simple Volume. The setup Wizard will appear. Follow the steps and fill in the partition size. You should see the VHD listed when you double-click Computer. In this example, it is named “Archive”.

Now that the VHD image has been created and named, the next step is to choose the data to backup. You may drag and drop as many files as the space will allow. With a partition of this size, a large amount of data can be stored over time. The computer used in this example shares data with other PCs on a remote network. Using Windows 7 Backup and Restore, you can backup all data on the PC easily and save yourself the trouble of dragging and dropping.

To use the new VHD for a complete Backup and Restore, follow these steps:

Open the Control Panel and choose System and Security. Click “Back up your computer”. You will then see this option:

backup restore files

Select Options in the Check backup settings then click Change Backup Settings and you will see this window representing all drives. Select the new VHD as the backup Volume by clicking on it and then click Next.

Notice that Windows 7 warns that this drive is on the physical disk as your system drive. This warning is there because this is not the ideal space for a final backup. It is rather easy to transfer the data from the VHD to an external hard drive at a later time as often as needed.

To select specific documents, rather than a full backup, highlight “Let me choose”. To allow a full backup, highlight “Let Windows choose”.

You can set a schedule for the backup to occur at regular intervals but always be sure to make a final backup on an external hard drive. On a network this is particularly useful. You can, for example, backup a shared network folder on a weekly basis and ensure that shared network files are continually backed up. Set it any way you like.

Firefox 8 Aurora Released, What’s New?

Firefox 8 Aurora Released, What’s New? HomeForumWindowsLinuxSoftwareInternet ExplorerFirefoxChromeOperaEmailContactAdvertiseFirefox 8 Aurora Released, What’s New?

Mozilla has just officially released the first version of Firefox 8 Aurora. Firefox 8 will reach beta stage in about six weeks and a stable release in twelve weeks. We already mentioned earlier this month that Firefox 8 will ship with a new add-on compatibility assistant that is giving users more add-on control the first time they update to a new version of the browser. The core change here is that users can enable or disable add-ons individually on first start.

Another change that we have already mentioned are improvements in third party add-on handling. Firefox previously allowed all third party add-on installations. This changes with the release of Firefox 8. The browser displays a screen that asks the user explicitly to allow or disallow the installation of third party add-ons before they are executed for the first time. It seems that this change is only affecting add-ons and not browser plugins.

A new option was added to the general tab of the Firefox options which could speed up the start of the browser for users who restore their previous browsing session. Instead of loading all tabs on startup, it is now possible to load the tabs when they are selected by the user. This is the same functionality that the previously reviewed Bar Tab add-on for the browser. The setting has been available before in the Firefox about:config configuration as browser.sessionstore.max_concurrent_tabs.

A downloads history has been added to the History window of the browser. It is now possible to find all previous downloads listed there next to web pages, tags and bookmarks. Firefox has previously saved the download history, the new addition only makes it more accessible in the browser.

Sören Hentzschel lists several under the hood changes on his blog. Firefox 8 now supports multi-process hardware acceleration which is a per-requisite for the upcoming Electrolysis project, which will move core browser elements like the UI, plugins or web contents.

Developers can check out the relevant changes on the Firefox 8 for developers web page.

Firefox 8 Aurora is already available on the official Mozilla “Future of Firefox” web page. Existing Aurora channel users should receive update notifications to update their version to version 8.
