Letter Frequencies and Keyboard Layouts

No comments :
I saw Mike Knuepfel's Keyboard Frequency Sculpture a few weeks ago and thought it was an excellent idea for visualizing letter frequency data.


The height of each key corresponds to how frequently that letter is used in samples of English writing.


I wanted to see how the layout of the most frequently used letters on a QWERTY keyboard compared to those on a Dvorak keyboard. Unfortunately, I'm no sculptor, and I couldn't see an easy way to slice and edit the original image to rearrange the keys, so I decided to use a color mapping instead.

The images below were created using the same letter frequency chart as the original sculpture. Pure blue is for the least frequently used letters, while pure red is most frequent.

QWERTY
Dvorak

Note that the majority of the most frequently used keys are on the home row in the Dvorak layout, but they're scattered all around on a QWERTY keyboard. The QWERTY layout originated in the very early days of mechanical typewriters, so the keys were arranged such that common two-letter combinations were placed on opposite sides of the keyboard so that the mechanical parts would not jam. The Dvorak layout was designed to reduce finger motion in order to increase typing rate and decrease errors. Despite these advantages, the Dvorak layout has still failed to catch on.

Top 5 Best free VPN's

No comments :
Using a free VPN is a big risk. If you aren’t paying for it, how is the VPN paying their costs? We highly recommend you use a cheap VPN instead, take a look at our guide here.

While most VPNs are priced under $10/ month this may be more than some people can afford so free VPNs are always appreciated. While these usually are limited in one way or another, the ones we have selected provide a great service at absolutely zero cost. 
It’s hard for a free service to compete with a paid one due to the downsides – which we have discussed for each VPN respectively – but the services we have selected will help you achieve privacy and security while carrying out your internet activities. If you do consider getting a paid VPN but are short on cash .


WE Prefer Froot VPN

Winner – CyberGhost

CyberGhost Logo
Positives: no logs, based in Romania, good client, accepts Bitcoin, allows P2P(on paid plans only) , shared IPs
Negatives: multiple simultaneous connections only allowed on most expensive plan, speed cap
CyberGhost is a large Romanian company who has been doing fantastic developments lately. With regards to security they are absolutely top notch, going as far as deleting your payment details after it’s been processed, are working on some security technologies themselves and are willing to support promising security start ups too! Not only is their security great, but other areas of their service such as the client and support are also fantastic.
Overall CyberGhost is a great provider, and while their free service has a number of limitations: speed, time, advertisement; it is superb all round.
Try Out the Best Free VPN Today!

2. SurfEasy

SurfEasy Logo
Positives: great speeds, 5 simultaneous connections, easy to use software, phone support
Negatives: download cap (more can be earned), no P2P
SurfEasy is a fantastic Canadian company, with aims of bringing privacy and security to the masses, so it’s no surprise that they provide a free service alongside their normal plans. All their plans come with a whopping 5 simultaneous connections, they have easy to use clients and good speeds.
Their free plan is just as good as the normal plan but it does come with come with a data limit of 500MB (can be increased to 1.5GB with a few tasks) which is only useful for occasional/ normal use. Also in order to be able to provide the security that they do, no P2P is allowed. If you’re looking for something different they also have a Private Browser USB product, which comes with an initial fee but is valid for a life time.

3. TunnelBear

TunnelBear Logo
Positives: entertaining, minimal logs, great performance, great clarity
Negatives: limited countries, no P2P, download cap
In many aspects TunnelBear is very similar to SurfEasy: they are Canadian, for the everyday person and don’t allow P2P. Even their pricing is similar for the paid packages. We found that TunnelBear’s support is better and their client to be a bit more useful and entertaining.
They provide 3 simultaneous connections, up to 1.5GB download limit and overall a very good company.

4. FrootVPN

FrootVPN Logo
Positives: TPB blessed, no logs, great performance, based in Sweden
Negatives: only Swedish server, won’t be free for long
FrootVPN is a very young company and provides a completely free, absolutely no limits VPN service. They’ve also got a lot of promotion from The Pirate Bay which says a lot about it’s quality and nature. Unfortunately, while great for P2P since they have Swedish server they aren’t very useful for geo-location locked content.
While free for the moment, due to their immense influx of customers this will likely to soon so make sure you take advantage while you can. It also means that their customer service is playing catch-up and therefore can take some time to reply.

5. VPN Gate

VPNGate Logo
Positives: fully open source, constantly being developed, mirror sites and daily updates
Negatives: educational so does log, no P2P, slow speed
VPN Gate is developed by the University of Tsukuba by Japan and servers are ran my volunteers. It is designed as a distributed VPN system, based off of Soft-Ether, which means it’s fully open source. All of these factors, including their mirror sites and daily updates, means that it’s a fantastic tool for avoiding government censorship.
Unfortunately this does mean that P2P isn’t really allowed and connection logs are kept for nearly 3 months from all the servers. Also since it’s ran by volunteers it does mean that speeds are unreliable, limited and can change very often.

Bonus. Tor

Tor Logo
Positives: very secure way (paid or unpaid) to maintain on-line anonymity (although bear in mind that nothing is 100% secure), easy to install and use
Negatives: technically not a VPN, Slow, no P2P
Not strictly a VPN service, but as a widely used free system designed to ensure online anonymity it seemed criminal not to mention the Tor Network here. The open source Tor client allows you connect to the internet anonymously through a distributed network (other Tor users) using a layered encryption service known as Onion Routing. This means that whenever you access a website your request will pass through at least 3 different computers (called nodes), with all information encrypted each time to provide a very high level of security. In addition to this, because your apparent IP is that of a random volunteer (of which there are literally hundreds of thousands), there is no way to even determine that you are masking your identity, which makes this service famously invaluable for dissidents living under restrictive governments.
The main downside is that it’s not fast, as your traffic is being bounced around volunteers’ computers across the world. The Tor Network also ask you not to use the service for P2P filesharing, as the amount of traffic involved puts a severe strain on the system and damages other users’ experience.
One use the truly paranoid may have for the Tor Network is in conjunction with Bitcoin payments, allowing them  to maintain complete anonymity when signing up to and purchasing regular VPN packages.

Conclusion

When your considering a free VPN make sure that you’re aware of all the restrictions imposed.
We believe that CyberGhost to be the best free VPN provider out there. This is due, not only to the quality of provider, but also since we believe it is the one with the most sensible restrictions. Their speed cap means that you’ll be able to use the service as much as you want while always being protected. Granted you will be disconnected every 6 hours but this shouldn’t be a big downside.
The other VPNs listed also have a great value behind them and since they are all free you can give them a full try before deciding which one you use – absolutely perfect. So if you’re wallet is tight but you’d still like to be protected while on the internet, we’d fully recommend trying one of these completely free VPNs. Have a look below at our summary below in case you haven’t made up your mind yet.

Top 10 Data Recovery Softwares

No comments :
You know where to find the most important files on your PC - the documents, the pictures, the music - and they're always available when you need them. So it's easy to assume that's the way it will always be.
The reality can be very different, though. Maybe you're not paying attention for a moment and delete something accidentally, perhaps there's a software bug, or something happens to corrupt your hard drive: whatever it is, the end result is that you've lost files, folders, maybe even an entire partition of valuable data.
Don't panic, though - there's a good chance that your files are still intact, somewhere on the disc. And if you act quickly then you may be able to recover everything. All you'll need is reliable free undelete software to run a scan, and we've found ten free tools which can help.
Read on for our pick of the best free undelete software...

1. Recuva Free


Conveniently available in a portable version, Recuva Free is very easy to use. A wizard asks you what type of files you're looking for, and where to search, then scans your system at speed (FAT, exFAT and NTFS file systems are supported).
Any files found are listed (with previews for images), and you can restore anything you need in a couple of clicks.


Recuva
Running the program in Advanced Mode provides more options, though, like a Deep Scan (much slower, but recovers more files), the ability to locate files containing particular text, and even an option to securely wipe files containing sensitive information, ensuring that no-one else will be able to undelete them.
Whatever mode you're using, Recuva is an excellent recovery tool, effective and very easy to use.


                                                DOWNLOAD

------------------------------------------------------------------------------------------------

2. Undelete 360


Undelete 360 is the free version of a commercial product, and so leaves out some useful features (file filtering, previews and so on). These still appear in the interface, though, and suggest you upgrade if you ever click on them, which can be annoying.
Undelete 360
There are no restrictions on the amount or size of the files you can recover, though, and otherwise the program is very simple to use: point it at a drive, it'll scan for deleted files, then you can view particular file types (JPGs, PDFs, videos and more) by choosing them from a tree.
Scanning speed isn't great, but Undelete 360 can recover files that other programs miss , and so it's definitely worth considering.
------------------------------------------------------------------------------------------------

3. MiniTool Partition Recovery


Standard undelete programs are perfect for recovering a few files, but if you've lost an entire partition then you'll probably benefit from a specialist application like MiniTool Partition Recovery.
The free (for personal use) program has a wizard-based interface which makes it very straightforward to use.
MiniTool Partition Recovery
Point MiniTool Partition Recovery at the problem drive, specify the area to be searched, and it'll scan for the missing partition.
A report will let you know what the program has found, and you can recover the partition in a few seconds.
You don't get a bootable recovery disc here, so if your system partition is damaged then MiniTool Partition Recovery won't help you very much.
Otherwise, though, it provides a quick and easy way to locate and restore lost partitions.
------------------------------------------------------------------------------------------------

4. Wise Data Recovery


It's hard to imagine how any undelete tool could be simpler than Wise Data Recovery.
There are no menus, no complicated options or dialog boxes: all you do is choose a drive, click Scan, and wait as the program locates any deleted files.
Select what you need, click Recover, and that's just about it.
Wise Data Recovery
Wise Data Recovery doesn't seem to work with FAT-based drives, though, recovering nothing from our test USB drive. It's only free for personal use, too. But if you just need something quick and easy to recover files from NTFS drives then it should probably be on your shortlist.
------------------------------------------------------------------------------------------------

5. PhotoRec


PhotoRec is an extremely powerful undelete tool with very few restrictions.
It's free for everyone, runs almost everywhere (DOS, Windows, Linux, OS X, more), works with most file systems and device types, uses in-depth knowledge of more than 200 file formats to help recover your data, and the bundled TestDisk can even recover a deleted partition.
PhotoRec
There is a complication, though: PhotoRec has an extremely basic DOS-like interface which is sure to intimidate many.
This doesn't make the program complicated - it walks you through every step - but the focus here is mostly on functionality, so if you're more interested in ease of use then we'd look elsewhere.
------------------------------------------------------------------------------------------------

6. FreeUndelete


FreeUndelete is aging, slow, free for personal use only, and didn't manage to retrieve anything from our FAT drive - not a good start.
Point the program at an NTFS drive, though, and the story is much different, with FreeUndelete locating all our missing files.
FreeUndelete
They're presented in a folder structure rather than a single list, making it easy to locate whatever you need, and they can then be restored in a click or two.
So while there are better undelete tools, you might want to keep a copy of FreeUndelete around, just in case your first choice doesn't recover something.
------------------------------------------------------------------------------------------------

7. Paragon Rescue Kit Free


If your PC has been trashed so badly that it won't boot at all, then any undelete tools you've installed previously will be useless. But Paragon Rescue Kit Free is different. It comes on an image which you burn to CD, and if disaster strikes then you just boot from the disc and go to work.
Paragon Rescue Kit Free
The program can recover a lost or deleted partition, for instance. The Boot Corrector can fix common boot problems and may be able to get your working again. But if not, Paragon's File Transfer Wizard helps transfer key files to another local drive, or burn them to CD or DVD. Overall it's a useful tool: grab a copy now, just in case.
------------------------------------------------------------------------------------------------

8. Glary Undelete


Another no-frills package, Glary Undelete takes a fairly basic approach to data recovery. There's really nothing to do beyond choosing a drive to scan, clicking Search, and waiting for the program to finish (although that might take a while, as it's slower than most).
Glary Undelete
The program does do a good job of recovering data, though, on both FAT and NTFS drives. And any files it finds are presented in both a single list and by folders, while you can also filter them by file type or name, making it generally easy to find what you need.
So while there's little in the way of extras here, Glary Undelete scores well on the fundamentals.
------------------------------------------------------------------------------------------------

9. Pandora Recovery


Unlike some of the competition, Pandora Recovery doesn't just present the files it finds in a single list.
You can also browse them in an Explorer-like folder view, or use an excellent search tool to filter them by file name, size, creation or "last modified" dates (so you could search for everything altered yesterday, for instance). Images can be previewed, too.
Pandora Recovery
Unfortunately file detection isn't always so reliable, particularly on FAT drives, and the program's quick scan didn't recover anything for us.
The more thorough Surface Scan mode did retrieve everything, though, so on balance we'd say Pandora Recovery is still worth a try.
------------------------------------------------------------------------------------------------

10. PC Inspector File Recovery


PC Inspector File Recovery did well in our tests, correctly locating the full set of missing files on both FAT and NTFS drives. These are clearly presented in a simple folder view, there's also a simple search dialog to help you locate files by name, and the program can then restore them to local or network drives.
Getting to this point may take a while, though, as the interface is a confusing mess of tabs (we'd recommend you experiment on a USB key or some other spare drive until you've figured it out).
PC Inspector File Recovery
It's a little odd that the program can preview files as text or a hex dump, but won't preview JPEGs. PC Inspector File Recovery deserves a look for its core engine, then, but you'll need some patience to take full advantage of it.
