Yes, you're 100% right, your post ends the discussion.
The problem with some people is that they have a "cinematic" knowledge of the infinite, with 0.9999... seen as 0.9999 with many more 9s jumping to the end as they scroll to the right.
BTW I don't see how such a discussion can make a news on/. , there are many proofs for this equality on the web and wikipedia... but the (0.999...)st post are funny.
See Arimaa, a new game with a board and set similar to Chess *but* with specific rules made to be difficult for a computer to play, and easy for a child.
How many options do you have when it's your turn to play with chess ? The average branching factor in a game of Chess is about 35, whereas in Arimaa it is about 17281 !
This is why a computer which can search to a depth of eight turns for each player in chess, can only search about three turns deep for each player in Arimaa...
This game is the new challenge for IA, easy for a child, difficult for a computer. A average human player wins against best programs.
Encryption key could be stored in self-destructing HSM.
I guest those HSM are expensive. Also they could be much more difficult to order than standard hardware.
I've been thinking of a custom hardware.
Of course implementation details must be secret, but there so many ways to achieve this goal, once the hardware discovered, just use another trick.
Of course they could also think we have something here.
But anyway the content is lost forever and such a device isn't forbidden.
We could also argue that it's built against thieves, to protect our data and miscellaneous investments.
Pros know that imaging the drive is the first step of any process.
Self-destructing custom hardware is the answer here.
It can be built with standard PC parts, such as a netbook hidden in a tower PC case. They open the case to get the drives and make an image. Case opening is detected by the netbook: a mouse button is used as a switch. But they don't press the right key on time and the netbook clear the master key of the encrypted usb drive. After that giving the passord is useless.(Also when the netbook is about to run out of battery, the key is cleared.) Don't tell you have a backup of the key.
Document the hardware setup on some unpublished papers, as a project or a proof of concept. Show the documents to explain they have destroyed the content
Here's a simple option that might very well work. Design a simple challenge response device with LCD which requests PIN code and then provides the long password.
You got a point here, well... two.
1) Challenge response
Can be used without specific hardware, think of a login with no password but a screen filled with ascii characters. You need to type in a response to the patern displayed, with a secret algorythm you invented and that you can master with your brain. (find a "&" displayed and then 3 cols, 2 lines from it, give the character there with a rot13, etc).
The response is used to unlock the real drive key.
Setup a fake login with an alternate password to unlock a second system, which blanks uncrypted drives at boot time.
2) Specific hardware
Make sure that anyone trying to get your drives at home will trigger a self-destruct mecanism. Document the system as a proof of data loss in case they force you to give the password. Actually the self destruction is a blanking of the encrypted master key of the drive. Don't tell you made a backup of it. Usually users don't make such a backup.
A boot script can handle the master key erasure in case you don't comply to the hidden boot procedure. Then if they get your laptop and switch it on without you arround, the key is lost. But they could be smart enough to image the drive before trying anything, thus forcing you to start the system once re-imaged. This is why a specific hardware (incl. UPS) with such a self-destruct defense system is required. The encrypted master key backup will prevent a full data loss in case the mecanism is triggered by a some unfortunate event.
I have a different idea... On your harddrive you will have an encrypted file that you will pretend to be protecting, but in reality you don't really care about anyone finding out what it contains:
SecretData.bin
Then on your USB drive you have a one-time pad file that is the same size:
OTP.bin
Someone gets a warrant, you hand over the USB drive and the password "hunter2". They XOR your OTP file with SecretData.bin and get an encrypted file, that they can decrypt with a common encryption algorithm and the password "hunter2". They now have access to the data you're pretending to hide.
The problem is that each time you want to change some document in the real secret file OTP.bin, you'll need first to decrypt SecretData.bin, then decrypt OTP.bin, change doc, crypt OTP.bin and crypt SecretData.bin with the new pad and passwd.
That's uneasy and if you make an automated procedure, it can give an hint about your trick.
Side by side, I prefer incandescent lighting for night time lighting. It feels better- and even the warm glow CFL's are not the same.
Yes, there's no point in having a daylight/sunlight equivalent at night.
Those blueish lights from CFL or LED (even the 'warm' version) are sending message to our brains: "it's day time". This can delay sleeping and cause biorythm drift .
I've tried all kind off bulbs and lights available. Strange result in the house, all those shades of "white".
My conclusion: we should have very warm lights at night, and for bad lighted room during the day, an other kind of light, like sunlight. Having very warm light at night keep telling my brain "it's night, prepare to sleep" and I feel better.
BTW : If you need instant light for short time, don't use CFL, but halogen bulbs. The same shape as incandescent bulbs but with a small halogen buld inside the big one. They save only 25% energy, it's x4 the price, but they are not banned. The light is brighter also, not very warm, and it render great colors.
I've also tried those LED strips. 600 white LEDs on a 5m strip (search ebay) and the warm white is okay, with a
As a big Mandriva fan, since Mandrake 5 - the begining - I 'm quite concerned with all the troubles of this company.
I run Mandriva for all my Linux boxes : file server, gateway, laptop,... (except the NAS with embeded vendor distro) .
From time to time I try some other distribution, but I always go back to Mandriva, I feel quite at home with it.
This time I really wonder if this could make me switch to Mageia... I'd like to hear some other fans : we will all give a try to Mageia but will you switch if the real Mandriva is still alive, making new versions ?
About the name Mageia, I don't mind, but I'd like to build the original Mandrake theme, with the magician, even if it can't be release officially due to registered marks.
If you watch the video at 3'01" the patern changes : discoveries are made on both "sides" of Earth ( read "sides" as if previous discoveries were made at front and sun were in rear position ).
Does anyone has an explanation to this new patern ?
I'm using Mandriva since 1999 with Mandrake 5, their first release. The version number was from RedHat. At the time it was a RadHat+KDE ready distrib.
I've never paid for it... maybe all users like me could be blamed.
I often had some glitches, but this distrib was and is still the best for my needs.
I agree about the poor community support and sometime invasive config file editing from gui assitants.
However they have a tremendous control panel, nice package management tool.
Well, since I started getting to bed late because I surfed on the net or watched to many movies, I was exposed to light and my brain to pictures, and then my circadian clock went out of phase.
No mystery here.
I just need to sync back to daylight and stop being addicted to home cinema and some forums.
I think those students experiment the same shift because of their late surfing/blogging/irc/texting and parties.
He said young people's body clocks may shift as they reach their teenage years — meaning they want to get up later not because they are lazy but because they are biologically programmed to do
I believe they start to sleep very late and thus need to wake up late, otherwise memory and concentration fail.
I've noticed such a shift with myself, when I started to go bed around midnight or 2am. Suddenly I was much less efficient at work in the morning but rather good around 5pm. No biological change. Just stupid habits.
Right after that line you say he doesn't see anything wrong with it. Have you not explained this to him?
Explain that Mac OS X is flawed by design and almost freeze with concurrent disk access. This is my observations, GUI reactiveness slow down to one minute or more for a click, with just 4 processes accessing files. That's a shame for a so-called multi-tasks system.
Also: Pop up nearby his office each time your are stucked by his file access. In case he wonder why just say you're waiting he has finished with your files.
Solution:
(so we'll never see again this useless color discussion)
Have a dozen color palettes pre-set. Lay down a handy desktop widget to switch from one to another with one click, no more.
There's some web sites with this css switch ability: one click instant change. And all the page have an new color theme.
Make the same for KDE and Gnome.
For initial color setings: make it random of time dependant: Sunrise color set in the morning, bright theme for noon, dim color theme for night, and various transitions.
I'm looking for a way to store digital info for years. There has been many/. stories about this.
My conclusion: go for printed 2D codes with CRC like Reed Solomon, using archival paper and ink jet.
So thank again/. crowd for giving all those clues about 2D codes printing and reading !
My contribution: Beware of those laser printing ! Solid ink can be peeled of the paper, leaving a blank page (with heat, time, vibrations, frictions). Prints last longer with quality ink jet prints, some are also water resistant.
BTW, does anyone have some good advice for the printing itself ?
No, I guess it came too late after MySQL well established and wide use.
Also Oracle Express hardware limits make it unsuitable for bigger db, turning clients to pricey Oracle Database.
This leaves some room in the medium sized db for MySQL as a free product, typicaly for grown up sites who started with this db.

Also failed on mine. NoScript and AddBlockPlus here.
I think this is a clear demonstration of the advantage of those modules : they protect you against unknown and future risks.

Use it several times, 4 pass.
