MEGAUPLOAD'S TIMEOUT


If you are only joining us, late yesterday the US Department of Justice shutdown Megaupload, arrested seven employees, & seized assets worth over $50 million (including 82-inch TVs, 108-inch TVs, 14 Mercedes, & other rich boys toys). This immense indictment poses lots of questions, but today we are going to look at of them: What happens to all of those files that people had stored on Megaupload servers?

This morning the net is littered with hundreds of millions of broken Megaupload links. There was no warning, no preamble: In the event you stored files on Megaupload, they are gone at least for now. So you have some idea of the scale of Megaupload, a speedy search on XDA-Developers for megaupload returns some 226,000 hits. There's hundreds if not thousands of forums on the net that are similar in scale to XDA-Developers.

In short, in the event you stored important files on Megaupload, I hope you had an up-to-date backup on your computer.

It is feasible that Megaupload servers will be brought back online, but only if Megaupload & its employees are found innocent & in all likelihood, the trial & sentencing process will take months. Even if Megaupload does return, there is no guarantee that your files will still be there.

There's always been major concerns about cloud services in general, and cloud storage (Dropbox, Megaupload, SkyDrive, iCloud, and so on). The first is privacy: When you upload knowledge to a third party, there's always the risk that they can look at the contents of your files. Some cloud providers securely encrypt knowledge, but plenty of don't. The second issue is knowledge security and integrity: Does the third party keep a tight ship against hackers? What happens if a hard drive fails? What protections have the cloud provider put in place to mitigate against natural disasters, bankruptcy, or being shutdown by the Feds?

The folly of cloud storage

For the most part, the only actual way of ameliorating these concerns is by doing an terrible lot of research before pushing in your chips. Even then, though, you would be hard pressed to discover a cloud storage provider that offers an simple way to migrate your knowledge in case of bankruptcy. If Dropbox decides to close down, the only way to transfer knowledge to another cyberlocker is to download it and re-upload to another service. If you're an enterprise customer using Microsoft Azure or Amazon AWS, you ought to probably be given help to migrate your knowledge to another provider. In the case of a federal indictment, though, I don't think any cloud provider offers a way out and if there's an earthquake, you better hope that they kept an offsite backup (and you can bet that consumer services like Dropbox or Backblaze).

At the finish of the day, though, the only other option is keeping your own backups on some kind of NAS and maintaining your own offsite backups which is feasible, and how plenty of companies and individuals select to do it, but rife with its own issues. Cloud storage is so simple it is the epitome of fire-and-forget that you forget about the risks and then Megaupload gets shutdown.

So, what happens to my files when a cloud service dies?

Assuming the midden hits the windmill, then, and your cloud storage provider goes offline without notice what happens to your files?

For consumer-oriented services that are more about backup than file sharing Backblaze, for example your files would probably stay in the digital ether, encrypted for all eternity. It's unlikely that a backup provider would ever be shutdown, but it could go bankrupt. In such a situation, you would probably be given a week or month to grab all of your information and then that would be it. There is no chance of Backblaze sending you a hard drive along with your information on, for example.

In Megaupload's case, where some one,000 servers (and thousands of hard drives) were seized, the Feds will probably pore through your files looking for facts that improves their chance of a conviction. It's  guaranteed that Megaupload stored the IP address of file uploaders, and the Feds could pursue individual copyright infringement cases at a later date. If Dropbox was ever indicted of similar charges, the situation would probably be the same.

Finally, at the enterprise level Azure, AWS, Rackspace, etc. It's likely that you would be given ample opportunity to recover your files, and you might even get help in migrating your information directly to another cloud service. In this case, if you're storing terabytes of information in the cloud, you could probably even request that your information be returned by FedEx hard drives.

MAKE YOUR OWN COPY OF WIKIPEDIA

Beyond your anger about conflicted representatives voting on disgusting & broken laws, though, you are probably experiencing a very different emotion entirely: loss. Loss for your beloved Wikipedia. The Wikipedia Foundation knows how important its encyclopedia is, it knows that blacking out the site for 24 hours will generate an uproar but most importantly, it knows that a blackout will make people query the future safety of of the most important services in the world. I mean, if SOPA was enacted & Wikipedia was made to close down, what would they do?

With today's blackout of Wikipedia, its editors & governing Foundation are sending a very clear message to Congress & other governments around the globe: In case you mess with the net the fabric on which Wikipedia is built there will be more trouble & strife than you can ever imagine.

Wikipedia, being the awesome site that it is, provides complete dumps of each of its encyclopedias to make the mirroring technique simple. With a tiny little bit of developer know-how, you can set up your very own Wikipedia mirror, available & editable by the public, like Wikipedia itself. Even if you are a standard web surfer without geek credentials, you can set up a local version of Wikipedia right on your computer, available at any time, irrespective of blackouts or shutdowns. Let's start!
Download a replica of Wikipedia

I have been thinking about this for the last couple of days, poring over potential solutions. Speaking to your local Representative or Senator (or member of parliament, if you are outside the US) is definitely a nice preventative step. But if Wikipedia actually goes dark not in a soft sense like today the only actual solution is to have a network of mirrors.

To start with, you will need to grab a compressed copy of the Wikipedia language that you need to reflect English, French, French, & so on from dumps.wikipedia.org. I strongly recommend you use a mirror, as the official servers appear to be slow. I used a fast Brazilian mirror, but its latest dump is over a month elderly.

You are looking for a file name that looks something like: enwiki-20120104-pages-articles.xml.bz2. The important thing is that the file name ends with pages-articles.xml.bz2.

If you are mirroring the English Wikipedia, this file will be around 7.5GB; other wikis will be considerably smaller.

 
Decompress Wikipedia

Now you have options:

You can cease reading now in the event you only require to generate a local mirror; otherwise, read on

In the event you require to make a web-accessible version of Wikipedia (i.e. an actual mirror of Wikipedia), you require to uncompressed pages-articles.xml.bz2. On Windows, this can be completed with 7-Zip. On Linux and Mac OS X it can be completed with bunzip2. The uncompressed English Wikipedia, without pics, is around 25GB.
 
In the event you require to make a local mirror of Wikipedia in the event you require a duplicate of Wikipedia on your computer, in case the world wide web-site suddenly disappears download WikiTaxi.It can take your compressed Wikipedia dump and turn it in to a browsable, searchable Wikipedia with a few clicks. The import technique will around an hour for English Wikipedia, or considerably more in the event you have an older computer.

Now Record Your History @ Facebook Apps


Life log: Timeline apps let Facebook collect stats on previous activity, like the travel log shown here.
Facebook won the loyalty of over 800 million users largely by getting them in to the habit of visiting lots of times to see the latest updates, comments, and photographs posted by friends. Now the site will also let outside apps provide even more content, and it will encourage people to spend time looking back over activity from months or even years ago. New features introduced at an event in San Francisco last night will enable users to automatically record their eating, reading, exercise, and other habits over time, share them with friends, and review their earlier actions.

The key to the new features is an update to the Timeline page that Facebook founder Mark Zuckerberg introduced at his company's F8 event last September. Now, with a user's permission, third-party sites and mobile apps can record details of what the person is doing and automatically feed that knowledge to the person's Timeline page through a "Timeline app" that sends the information to Facebook and provides the necessary permission and privacy settings.

"Your timeline is not a way to tell your story based on what you are doing on Facebook, but using your activity out in the remainder of the world as well," said Carl Sjogreen, director of platform products at Facebook, at the launch event.

Fans and researchers have experimented with comprehensively logging their lives for years. In 1998, for example, Microsoft researcher Gordon Bell began trying to digitally capture as much as they could about everything they did. But Bell and others have often found that browsing and reviewing their records introduced a greater challenge than capturing them. Facebook's new design could help people do both.

Facebook's hope is not to hook in users with more experiences, but also to make use of the new trove of information that Timeline apps will provide. The knowledge could help the company's efforts to target ads more cleverly, although Facebook says that for now, information from Timeline apps is not used in that way.

DELETE FOREVER

There are a few methods to delete files from the computer. In Windows, they can hit the delete button or right click any folder or file & select delete to delete the file or folder. By default, this will take the file to the recycle bin & then they can empty the recycle bin to delete the file permanently. But this won't delete the file from the computer. It remains on the hard drive until it is re-written by some other knowledge.
One technique to delete the file without taking it to the recycle bin is to make use of Shift-Delete in lieu of only delete. But this also leaves the files on the hard drive. There's plenty of programs that can securely delete files permanently from the computer but the issue with them is that they need to be installed on the technique in order for them to function. If you are using a public computer, it is not always feasible to put in those programs.

RightDelete is a small transportable utility which can permanently delete files from the computer without being installed. It is very simple to make use of. It offers options on startup:
  1. Explorer context menu file/folder links
  2. Explorer context menu SendTo link
  3. Desktop shortcut link
Selecting the first check-box Explorer context menu file/folder links will add a context menu item so that you can right click any file or folder in order to securely delete it.
You can take it with you in your portable pen drive & use it on any computer or laptop In case you need to make use of it permanently then make positive that you unzip the utility in a folder in order for it to function properly..

FINGER TOUCH MOUSE DEVICE



There are not enough numbers to count the times I have been annoyed by the click and clack sounds that come from a computer mouse. While relaxing at home, getting a nice cup of tea prepared and sitting down to a good book, the sounds from the mouse and keyboard will start up and then I can concentrate on nothing else.

The beginnings of the ultimate days of peace are at hand. Microsoft has made a touch mouse that is completely clack-free. Multi-touch technology lets you tap and slide on the mouse instead of hammering down a button on either side, or scrolling with something that sounds like you’ve gone too far into the shoulder on the road. This mouse can also function on any surface whether it be smooth and glossy or rough and uneven, which makes it much more appealing than most other of it’s kind. It works off of a USB Nano transceiver and has a rather commendable 30-ft range. At only $80 a pop, it’s a wonder everyone doesn’t already have these to replace their old loud ones.

INSTRUCTIONS TO INSTALL THE OPENSUSE

OpenSUSE is another great Linux flavor that you can install and play around. The latest version is having excellent new features, appearance and working surroundings. This tiny guide shows how to download OpenSUSE 11.4 and install on VMware with working VMware tools by Easy Install process, so you can fine-tune the screen resolutions and get more more options in virtual machine.

If I can shift my all programs and drivers to OpenSUSE 11.4 from Windows OS, then definitely I will think to move on. The latest version looks great and works smoothly. I think it is having major changes from earlier version 11.3.

The latest VMware products support 11.4, so it is a straightforward installation. Since it can be done by VMware simple install which is like unattended installation, the all installation steps will be done automatically including VMware tools. Successful VMware tools installation on OpenSUSE 11.4 will enable us to change the screen resolutions, working sound, network, full screen mode and unity mode to basically work with visitor and host Operating Systems.

Installation Steps – OpenSUSE 11.4 on VMware

Select the appropriate download method and correct 64 bit or 32 bit to suite your physical computer processor.
2) Create a new virtual machine in VMware workstation or VMPlayer.
3) Mount the downloaded Opensuse ISO file, VMware will detect the OS type automatically, this indicates the possible Easy Install method
4) Next screen to enter the user details which will be used by ‘Easy Install’ to create user account inside guest OS.
5) Modify the virtual machine name and location if you like. You can change the default hardware option in next screen. I started the installation with default options.  Press ‘Customize Hardware’ if you like to modify the hardware settings.
 6) As expected, installation will start automatically, you do not need to do anything during the installation.
7) Give enough of time to restart automatically and install VMware tools. Guest OS will be waiting for the password to enter which you created in earlier step –4.
 8.) That’s it, installation is done. Network, sound and more screen resolutions are working well inside OpenSUSE 11.4 virtual machine. Also Unity mode works fine which allows to access Linux guest OS from Windows host computer’s desktop.
Enjoy and play with the latest Linux release with working most of the choices inside virtual machine. I will try the same with Oracle VirtualBox and update this weblog in coming days.
