Show File Extensions in Windows 7

2011-01-23 Leave a comment

I find it strange and somewhat annoying that Windows 7 hides file extensions by default.

To show file extensions in Windows 7:

  • Click the Windows Start button Windows Start Button and select Control Panel
  • Click Appearance and Customization and then Folder Options. You can also get Folder Options to appear by simply typing it into the search box in the upper-right corner
  • Select the View tab
  • Uncheck the box under Advanced settings that says Hide extensions for known file types and press OK

KeePassX: Open URL Function in Ubuntu Linux

2007-06-09 2 comments

The “Open URL” function does not work with the default settings for KeePassX in Ubuntu Linux. To make it work, go to Extras/Settings/Other tab and change the “Browser command” to firefox %1

Now when you highlight an entry and press CTRL + U, it will open a new Firefox window or tab.

Huge Security Problem in AOL’s Login Mechanism

2007-05-13 Leave a comment

As if there weren’t enough reasons not to use AOL already. Now someone has figured out that AOL’s password system completely disregards any characters after the first 8. This makes it much easier to guess people’s passwords, which is an obvious security concern.

When the Windows Installation Fails

2007-01-18 Leave a comment

When the installation of an operating system doesn’t go smoothly, it can quickly turn into a major nightmare. In some occasions there seems as if there simply is no solution, but there is! Standby for the answer…but first – my story:

I have an old Compaq Presario laptop that has always been a lemon. This thing would always would hang or do other strange things. At one point the thermal pad on the processor fried. The symptom for this is the machine just powering down hard at random. (Like you yanked the power cord) What happens is the BIOS shuts down the power because the processor became to hot. After replacing the thermal pad and later the hard drive, I determined it was finally time to reinstall the OS.

When attempting to install Windows, the laptop would simply go nowhere. I tried multiple times with valid media and it simply would not load. After giving up on Windows, my answer was to install Ubuntu GNU/Linux instead. The Ubuntu Linux distribution installed flawlessly, and I even used it to connect to a wireless network for a while.

If you are thinking of trying a Linux distribution, just go for it. Use an old PC that you have sitting around just to get something going. Linux runs great on older hardware that would not work with Windows. And the best part is that it is free and comes with a great support community!

Export From RoboForm to KeePass

2007-01-16 40 comments

Update 29Nov2009: Thanks to @jimjon for pointing out that new versions of KeePass support importing of passcards from RoboForm.  This eliminates the need to go through the tedious steps below.  KeePass continues to improve.  Show some support!

RoboForm is a fantastic program, but the fact that it doesn’t run on Linux is a major problem for me. KeePass seems like the best alternative, but it does not currently support a direct import from RoboForm. I have almost 140 passwords, many of which consist of 10-30 random characters. Typing these in manually would be a major headache, so here’s the best hack that I found.

  • Download the trial version of PassCrypt
  • Import your RoboForm data to PassCrypt
  • Export your newly imported data from PassCrypt to a CSV file. You don’t need the headings.
  • Download a CSV file editor – I recommend CSVed
  • Once you’ve installed CSVed – go to Tools, Options, Double Quotes. Click the box next to “Save CSV File With Double Quotes”. If you don’t select this, your import will fail. KeePass requires that the data is between double quotes. If you try to use Excel it will strip the quotes from the file and the import will fail. Believe me on this one – I’m saving you a lot of time and trouble.
  • Open the CSV file you exported from PassCrypt in CSVed to modify the file.
  • Put your columns in the following order: “Account”,”Login Name”,”Password”,”Web Site”,”Comments”. You don’t need these column headings in your CSV file – you just need the columns in this order.
  • If you have any ampersands (&) in you passwords – do a find and replace in CSVed to replace all instances of & with &. It appears as if PassCrypt did this during the export to CSV.
    • Update 8/6/2007: At some point the WordPress WYSIWYG mangled my post in regards to HTML special characters. The bullet point above may have problems with the display of ampersands. The idea is that during the process of moving passwords from one program to another, the ampersands in your passwords may be replaced by the html character code. This will obviously cause your passwords to not work. Thanks to skibum mark for the heads-up.
  • You may notice that many of your usernames or passwords are missing from the exported file. This is because RoboForm captures these values from websites that use different terms to identify them. One may be “username” while one may be “logonid”. You’ll have to manually enter these missing values in CSVed or wait until the file is imported into KeePass.

I told you it was a hack. Someone needs to write a plugin to import passwords directly from RoboForm into KeePass. Until then – use the steps above. If there is enough interest I’ll put together a better tutorial with screenshots.

Kudos to Alana Post for the article RoboForm to KeePass – which outlines the basic steps.
