Manage your passwords with KeePass

Who needs a password manager anyway?

In this modern era, more and more critical information is stored behind passwords. Access to your money, your private conversations, pictures, grades,  and more… increasingly almost every aspect of your life is locked using only a few letters and numbers.  How do you secure all this information, on so many sites, and keep it from getting into the wrong hands?

One thing you never want to do is use the same password all over the place, or you could end up like this tech “expert”.  But how are you supposed to keep track of them all? Saving them in your browser is less than ideal. Writing them down can be disastrous. Memorizing all your passwords becomes increasingly complex as you increase the number of accounts you maintain.  Oh, and you’re supposed to change them regularly?  Suddenly the task is next to impossible.

What you need is a way to manage all your passwords, while keeping them safe from prying eyes yet available to you without fear of losing them.

Boar: python-based personal file repository/backup solution?

Yet another file repo?  Boar seems to fit a niche for personal long-term backup and maintenance of files, including larger files which the likes of SVN tends to choke on.

To summarize: the ideal storage for your important files should have the following properties.

  • File integrity must be guaranteed by checksums and easily verifiable.
  • File history is an essential part of your data. It must be backed up and stored redundantly, just as your other data.
  • No accidential changes in the storage should be possible – this especially goes for data deletion.
  • Storage must be efficient – collapsing redundant data blocks when possible.
  • There should be no artificial limits on file sizes.
  • The storage format must be very simple, so that software obsolescense will not render the storage unreadable.
  • It must be fast to access the data. This is not a backup archive, this is the primary location of the data, and therefore speed is important

The project seems to have the correct notion for a day-to-day file backup and history system.

Teamspeak… Ventrilo… Mumble?

Mumble sounds like it’s becoming the opensource voice chat for gaming that I’d always hoped teamspeak or ventrilo would eventually turn into.

This bears investigation.

MaximumPC gives some fairly solid upgrade advice

For those gamers or hardware enthusiasts looking for a decent upgrade, MaximumPC has a pretty good overview of parts and technologies currently in the “sweet spot”.  This article is aimed at the PC upgrader, but is just as valid for the do-it-yourselfer building his own rig on a budget.

Following on the heels of that, ExtremeTech has come out with an article for upgrading a gaming PC, with 6 different price points.

Serverless NAT to NAT communication? A clever solution

Serverless NAT to NAT communication?  A clever solution:

I will have to test this one out in various environments and report back.

Windows could not start because the following file is missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SYSTEM

Ahh, another day, another Windows Update auto-update gone horribly wrong.

I woke up to this:

Windows could not start because the following file is missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SYSTEM

I tried to boot from my XP SP2 slipstream disk and go to a recovery console, but even there I could not get the file to copy or rename. Chkdsk tried but failed.

Here is how I got my system back up and running.

It wasn’t helping that my C: drive is a RAID 0 stripe across 2 disks; this made it pretty much impossible to drop the hard drive into another machine and fix it from there.

To fix the issue, I did the dreaded reinstall. However I installed to C:\WINDUHS instead of the default. This allowed me to get a semi-functional XP up and running. From there, I went to start, Run, REGEDIT.

In the registry editor, I highlighted HKEY_LOCAL_MACHINE, and then went to File -> Load Hive.

I located Windows\System32\Config\system and added it. REGEDIT asked for a name so I used “BADBADBAD”.

REGEDIT complained that there were errors in the hive, and that it had to repair it, but that it was successful. VOILA!

Next I unloaded the BADBADBAD hive by selecting it and choosing File… unload hive.

Now, when rebooting I had to choose the older boot option (which came up second… you can edit your boot.ini if you want to modify this), but I got my old system back! Not only that, but I have a handy WINDUHS install at the ready should anything cause my system to become unbootable in the future.

TinEye: the google of image searching

How did I miss this site? will take your image or link and find out where it comes from, or at least where else it is on the internet.  This bears further testing!  Apparently still in beta.

Google introduces Public DNS service beta

Google has announced its own DNS resolver.  In typical Google fashion, it promises to be faster and more reliable than whatever DNS server NBC, err I mean Comcast is currently bogging you down with.

The scary part concerns the fact that now Google will ostensibly know not only everything you search for, but every IP your computer connects to regardless of search.  But hey, “don’t be evil” right?

Even the IPs are badass and easy to remember:

The Google Public DNS IP addresses are as follows:
