Stateless password keychains

There are several solutions to saving you from the hassle of having to remember a multitude of passwords. One common way is to install a password manager . These store your randomly generated or manually created passwords in an encrypted manner. You need to devise a method to synchronize these passwords between your devices. A different approach to this problem is to generate all your passwords in a deterministic manner on the fly without saving any state. This spares you from the pains of synchronization and potentially losing all your passwords in case your vault gets damaged. Here are a few of these: https://github.com/waldyrious/hash-my-pass/ http://plevyak.com/dpg.html https://passwordmaker.org/ (old site: http://passwordmaker.sourceforge.net/ ) http://angel.net/~nic/passwd.sha1.html Of course, both methods require using a really strong master password that you can learn by heart.  My personal recommendation is to use at least two separate vaults with diffe...

Ubuntu 11.04 vs. Intel 865G

Hm, it looks like this post has stuck in my drafts for some years now... Compositing produces a considerable amount of flicker and the display is obstructed by random image parts. dmesg is also full of page flip errors. Solution: cat >~/.drirc <<EOF <driconf> <device screen="0" driver="dri2"> <application name="Default"> <option name="vblank_mode" value="0" /> </application> </device> </driconf> EOF service gdm restart via https://bugs.freedesktop.org/show_bug.cgi?id=30654#c10 and http://pastebin.com/3gr5VbHY Also needed to append the following to the kernel command line, or else I got a lot of squashfs block read errors: acpi=off noapic ide=nodma all_generic_ide pci=nommconf

Protecting your E-mail address from spam bots

Common wisdom helps you achieve that: never publishing your contact information in a trivially machine readable form (e.g. writing it out in the clear at the top of your site, by the way: click here to see my E-mail address book ) and avoid getting into circumstances that can transitively result in the former case. I, however, can give you some more advanced advice. Create accounts with names that are randomly generated and are at least 8 character long each. Don't let your more valuable addresses get into other people's address books, because malware can easily harvest it from there. If only one in a hundred will get infected, your address is breached for good. So you mustn't give away all of your addresses to everybody. Don't hesitate to change your address if you receive spam: your digital signature can identify you regardless of location. In fact, only your digital signature can identify you, and the address a given message has been sent from is irrelevant, bec...
