Secure online backup providers review

I can not image anyone would use a (free or not) online backup service without pre-file transfer encryption. It essentially means giving strangers (= the people who work at your backup provider) full access to all your files and photos. Not a good idea.

Now, but services with pre-file transfer encryption do not open-source their client software that does the encryption. So you have to take their word for it that they really do encrypt their software.

A. Online backup services with pre-file transfer encryption:


1.  IDrive (www.idrive.com )

Online backup services with pre-file transfer encryption and open-source client software:


Really? None?

Only an open-source clients allows user to verify the files are correctly encrypted pre-transfer.

Online backup services without pre-file transfer encryption:

You should not put files on these services that you don't want other people to ever see.

What’s the Difference Between Sleep and Hibernate in Windows?

Sleep mode 

All actions on the computer are stopped and any open documents and applications are put in memory. You can quickly resume normaloperation within a few seconds. Sleep mode is basically the same thing as “Standby” mode.

Pro: Faster wake-up
Con: Still uses power

Hibernate 

The Hibernate mode saves your open documents and running applications to your hard disk and shuts down the computer.  

Pro: 0 power consumption
Con: Somewhat slower wake-up

To confusing? Simply do what I do and use the regular shut-down :)


Mozilla Electrolysis (e10s) Release Date and Resources

The goal of the Electrolysis project ("e10s" for short) is to run web content in a separate process from Firefox itself. It is an important project with potentially breaking changes for addon developers. I find the Mozilla Resources ...confusing. So here is my e10s cheat sheet.


e10s Release Date


E10S is scheduled for Firefox 36 - February 17, 2015.

According to the Rapid Release Calendar Firefox 36 development begins Oct 13,2014. This is the version of the browser where Firefox's multi-process architecture will be moved from channel to channel (Nightly > Aurora > Beta > Stable) so that it is released to the stable channel of the browser on February 17, 2015. (Source =?, I read it on Ghacks)

e10s - How to test

You can test e10s in its own window, like Private Browsing, using the 
Nightly channel's "File > New e10s Window" menu item. (Source https://groups.google.com/forum/#!topic/mozilla.dev.platform/q0Ku_8j26Pc )

How To Automatically Logon To Windows 8 or 8.1


  • Open the RUN prompt, type 
    netplwiz
  • Then the  Advanced User Accounts program will opens. You see a list of users.
  • Click (= mark) the user that you want to autologin.
  • Now, above this list of usersuncheck the box next to "Users must enter a user name and password to use this computer".
  • Click the OK button at the bottom of the window.
  • When the Automatically sign in box appears, it has the user name prefilled. Just enter the password twice.
    Note: If you're using a Microsoft account, be sure to enter the entire email address that you use to sign in to Windows 8 with in the User name field. What defaults there might instead be the name associated with your account, not your actual user name.
  • Done!

Bluetooth Tracking Devices Review

Ever lost luggage? Or your mobile phone? Then a Bluetooth location tracking device (aptly also called Lost-Item tracker) might be for you. Here is a list what is currently on the market:

  • Tile
  • StickNFind
  • BluTracker
  • PebbleBee
  • XY Find-It
  • Bringrr & BringTags
  • Find’Em Tracking
  • Linquet
  • PROTAG Duet
  • Lupo
  • iCookie
  • Click N'Dig
  • Wallet TrackR

The review is easy: All of them require a battery and cost between $30-$100. Unlike the WallStreet Journal I think this is ridiculous. It is the electronic version of Coal Rollers.

In contrast to Bluetooth, NFC (Near Field Communication) would be an ideal candidate for this application, as the tags require no battery. But physics still puts some hard limit on their range. More than 20cm are currently not possible.

As far as I am concerned, I came to the conclusion that this is nothing for me. Way to much battery waste! So I decided I'd rather continue use my build-in brain for this. It is not that bad after all.

But wait! There is one solution that does not require a battery. It is
Alas, this one does not exist yet and is most likely a scam.

Software Development Outsourcing - Top 5 Portals

Poster announcing employment opportunities
in business process outsourcing (BPO) operations in Bangalore. 
Outsourcing software development came a long way in the last decade. Before the turn of century this was a domain for larger companies that could afford a physical presence in the “source” countries. The emergence of outsourcing portals made it possible for small companies and individual developers (freelancers) to meet in a virtual and secure space. The pioneers in this market were Elance and Rent-a-Coder. For outsourcing software development Rent-a-Coder was by far the best choice, due do its reliable rating system for sellers and buyers and a good escrow and qualified arbitration service, which was specifically fine tuned for outsourcing software projects. Alas, they got acquired and absorbed by Freelancer.com in 2012. => So which portal is the best in 2014?
