and this was my windows (still XP / NT 5.1) after i adapted the NoNamePro windows theme, set my system font to Times New Roman and built a little LiteStep theme based on Devastation. (i added the status bar, and later a little "m" button for the start menu, tho.. :P )

protecting password input with acoustic one-time-pads


think of a situation where you sit in the tram next to someone and you want to unlock your portable device. it’s pretty stupid that anyone (including surveillance cameras) who watches you typed can basically see your password. the same problem occurs on stationary computers when you are (*gasp*) not alone in the room.
this is a proposal of a fairly simple way of encrypting a password on it’s way from your brain to the computer.
 
here is my solution:
  1. for easy in-brain encryption we recommend a hexadecimal numeric password. let’s take “5A491C6E” as an example. of course, important passwords should be longer. a hexadecimal keypads offer decent data rate on a small area and it’s regularity helps visualizing the encryption.
  2. when being prompted to enter the password (for example tapping on the “enter password” field) you are given a random digit over the headphone. that is the key for encrypting the first digit.
  3.  you remember the first digit of you password (5) and add it to the digit you just got over your headphone (let’s say it’s 2) and add them (7). don’t carry anything, if you get “13″ just enter the “3″.
  4. you type in your result on the keypad. you recieve the next random digit to encrypt the next digit of the password and so on. with some practice, this should go pretty quickly.
  5. as you type it in, the device can decrypt each digit with the key it gave you. you hit enter and you’re finished.
the key you recieve acts as a one-time-pad, which is, in itself, resistant to cryptoanalysis. much more importantly, it is easily performed in the head.
the key might be spoken by voice synthesis or might be encoded with tones in some way.
 
obviously everyone who hears what you’re hearing and sees what you type can still decypher your password.
it should be transmitted as quietly as possible. sound-insulating headphones are very advantageous.
other possible attack vectors would be the head phone cable’s electromagnetic emmissions or involuntary gestures or eye movements that may perhaps reveal the key or password (training should help with that). but any of these measures are much harder than watching a person type.
and, of course, insecure hardware and software (in particular proprietary operating systems) can offer volunerabilities or back doors on their own.
this image may help illustrate the process:

duochrome

this is a preview for icons i am been working on. i am thinking of raising a little money to make it into a full theme. the result should be public domain, tho. feedback and suggestions (especially on the money-making part) are greatly appreciated.

a somewhat-pseudo blackletter font in a pretty strict triangular raster. i guess it resembles protogothic most closely. the capitals are a bit whacky i tried to make them always resemble the minuscles. but capitalization is a dying craze anyway. :P

there is a dangerous misunderstanding about "freedom of religion", as it leads some people believe that they have special "freedoms", because they are religious.
this is religious privilege and fundamentally what freedom of religion is opposed to.
the reason why you are propably allowed to build a religious building or celebrate a religios holiday, is merely that you are allowed to build and celebrate anything you like, as long as it doesn't harm anyones freedom.
you have the same right to religion as you have to a fancy dress: if you can achieve to have it without harming anyone, then you may go and get it.
you right to "follow" religious literature is the same as to "follow" the story of "Frankenstein", a telephone book, or the or the operation manual of a sex toy.

copyright means that you can stop people from saying something if you said it before. copyright is a case of censorship by it's very definition, and censorship is a crime. many crimes have beneficiaries, and some of the beneficiaries may even be artists or scientists.
and yes, we should value art and science much more than we do currently. but we may do this by giving them inspiraton, supporting them financially and mentally and by sharing their works. it does not give anyone the right to beat, rob and jail people to silence.

end copyright.

brmpaw and binary cyborg clocks

(sent to the @brmlab mailinglist)

hey everyone :)

as i just checked your wiki and i was especially attracted by your neurohacking section. i love it, keep on this awesome stuff. but that just btw…

on your page about brmpaw there are plans mentioned to integrate a clock into it.
and i have a soft spot for clocks as they are a part of my efforts to reinvent civilization.
to be more precise i'm a lover and advocate of binary/hexadecimal time, dividing the day in 2^16 pieces ("hexsecs"), which are a little longer than an 'ordinary' (1/24/60/60) second.
your clock plans brought me the idea to just send the 16 bit of daytime information every hexsec as haptic or electric impulses to the users nerves, which is about 12,136296296 impulses per second. or non-impulses in case the bit is zero.
i also think about the perception of geocoordinates and compass direction in a similar fashion.

i wonder if such complex signals would be too distracting or how beneficial it would be that no memorization of previous time-states is required to percieve the daytime at any given moment. and most important weither binary signals with such a fequency are percievable effortlessly.

anyway i'm greatly interested in any sensory/cyborg experiments you do, and i would love to learn more. (i'm not so much into electronics and  µCs tho…)

greetings from saxony / germany / the internet,
sofias.

hexadecaphonic (16-edo) keyboard design.

the hexadecaphonic scale defines 16 tones in one octave (one doubling of frequency).
you can read the clover leaves as binary numbers.

colors: black = 0, white = 1

places:
1  3
2  4

one step left is 1/4 octave (3 traditional 'semi'tones) higher.
one step up is 1/16 octave (3/4 traditional 'semi'tones) higher.
