All your ways of attacking the mention IDS scheme from the parent can work, given the right circumstances. Basically what it comes down to is that if the attacker gained access successfully and is in control of the targeted machine it can always send out messages, as if it was not infected. At this point it is too late trying to detect anything. With a challenge-response scheme you might be able to ask for the exact contents of/usr/bin/md5 but you will never be able to tell whether there is also a/usr/bin/md5_modified on the server which is hidden and only used at some point.
Two alternatives might be possible to still have a relatively easy to manage and save IDS: You can boot from a r/o media every night and use this system to do the file integrity check (hard to automate a single boot from cd) or you could send a large number of log statements about logins, running processes, firewall logs to a different machine where any unusual events trigger an notice to check the system by hand.
It is definitely possible to use some narrow bandpass filters. In the infrared region there are various filters for available that have a wavelength window of 10 nm at 1000 nm. These filters are not available at Walmart, but they are not too costly either. Depending on size, quality, wavelength and other parameters you should be able to buy some for $50 (Thorlabs).
To actually hack the Kinect you have to test, whether there are other infrared filters used and if the camera is sensitive enough at different wavelengths. I don't think the properties of the reflecting materials should be of any concern. The reflection of materials in a household room should not change for a small frequency difference in the infrared region.
Using a time-multiplex approach with shutters or just software which switches the cameras on and off might work well in theory but should be rather impractical to do without significant changes to the Kinect hardware.
Desktops, not laptops. More reliable, cheaper, faster. Only get laptops if there is not enough desk space in the office. Avoid thin clients.
Brand: Do not build them yourselves. Get something from a big supplier. Get the business line, Dell or Lenovo.
Authentication and user managment: Do not bother below 30 persons. Above: Active Directory, LDAP,...
Internal media server: If your users are competent a simple file server will be enough. Dell or Lenovo. Lots of SATA disks. More disks for onsite backup. Get offsite backup, too.
Web server: Do not inhouse your webserver. It provides you with no real advantages. You cannot compete on connection, reliability, UPS, etc with a big hoster. Get a development web server for testing inhouse
OS and software: Stick with what your users are competent with. Ubuntu is really nice, get it with enough Linux experience. Mac if you have enough money. Windows 7 is good and works.
General: Avoid "big" solutions. Do not blow money on anything were a salesmen visits your NGO. Learn from other NGOs.
In the natural sciences Wikipedia is an important tool in research.

There are quite a few points to consider how the game should adapt. Besides the simple fact that the main focus should always be on the fun aspect of the game I have two examples on my mind of good and bad adaptation. In neither cases "rewarding mediocrity" is a real concern.
The bad example of adaptation can be seen in quite a few FPS. Before adaptation there were different skill settings from beginner, easy, normal, veteran, nightmare. Now the game constantly assesses how well I am doing and as a somewhat experienced player it increases the difficulty level quickly. Now there are the basic enemies around the corner, who I had plenty of fun slaughtering early on in the game, which are now equipped with x-ray vision and one-shot-to-kill handguns. While the player may still manage to progress by being much more careful it just seems unfair and not fun anymore. So basic enemies should always be easy to overcome, no matter what.
A good example is the A.I. director from Left 4 Dead. Quite often the teams are unbalanced and it stops being enjoyable if you know that your team does not stand a chance at all. Sometimes right at that moment the A.I. notices and throws in an extra tank. This can often mess up even an organized team and now it immediately feels more balanced. Also the basic zombies are always easy to kill, the adaptation changes their number not their individual strength.
A simple way around automatic adaptation is to continually look how the player progresses into the game and then at the end of a level their commander just asks: "You exceeded my expectations, do you want a tougher challenge next time?"
LTSpice is free as in beer and works nicely even with more complicated problems. There is only a windows version available, but Linux support with wine should not be a problem. http://www.linear.com/designtools/software/
A dirty trick that is still around in even the newest X86 processors and causing problems for hardware engineers and has security implications. The first xbox was hacked partially because of the A20 gate (pdf description of vulnerability) and maybe Intel will stop using the A20 gate in the upcoming Nehalem generation.
Why don't you just read the website you are citing:
Scientific theory and evidence suggest that, once emitted to the atmosphere, these compounds could significantly deplete the stratospheric ozone layer that shields the planet from damaging UV-B radiation. Man-made chlorines, primarily chloroflourobcarbons (CFCs), contribute to the thinning of the ozone layer and allow larger quantities of harmful ultraviolet rays to reach the earth.
Parent is right: money is not the argument, that is worth the switch. Software companies, Microsoft included want students to learn MS Office, Adobe, Matlab, Autodesk Inventor, etc. Some companies even give their student versions of really expensive software packages away for free, just have a look at Autodesk.
For the students it is of great value, if they are able to work efficiently with open source software. Just a few days ago I helped someone to switch from Endnote to Zotero+Jabref. It was quite a pain to convert from the Endnote format to something more open like the Bibtex format and there are several websites which show you 10 different hacks how to do it somehow.
With open source the file format is always documented, at least in the code itself. So if you want to work with your reference in 5 years without upgrading Endnote to Windows 8 this is the only sane choice.
For science in general it is necessary to check your results carefully and be able to reproduce other people's work somehow. How are you going to judge a paper claiming: "We simulated bla with this $$$ software package and it looks marvelous"?
Besides file formats and reproducibility in my opinion it is in most cases better to teach something that can be useful for the next 5-20 years, instead of some fast moving target. Software vendors often change their products and break backwards compatibility (Labview is great, but going back 2 versions is a no go) not because they invented this new must have feature but to sell the next version. If your students can do statistical analysis in Gnumeric and R they are well equipped for advanced work and do not have to worry about all the errors in Excel (statistics in Excel).
This would be easy to implement and some games show a similar behavior. Still this is not widespread because it just does not add to the gameplay. A longer timeout for alertness would just mean, that you need to wait in a dark corner for a long time until the enemy finally goes back to "no alert". I certainly don't want to be punished for a tiny mistake by having to wait forever. In a simulation rather than a game the enemy should not only react by increasing the alertness but calling for additional patrols, etc. which would reduce your chance of success significantly.
It is a fine balance between "not noticing a dead body" and "call for everybody to eliminate you".
I am not a specialist for superconducting materials either but I think they think that the material is something like a type 1 superconductor with a very high critical field Bc.
The material can only be of type 1; that means complete expulsion of magnetic flux, if the samples are single crystalline. Their actual measurements show a high critical field Bc2 for polycrystalline samples.
So it is not "immune to magnetism", which can hardly be the case for superconductors but might allow AC current transport without hysteris losses (as in type 2 superconductors).
Before everybody complains how he could have done the analysis much better I think it reflects quite well the approach a lot of people would use here. If my friend would ask me about a failing apache server my first reaction would not to dd the whole system.
Unfortunately the article is a little low on details about the running configuration. Ubuntu 6.06 seems like a solid distribution security wise, so where all current patches installed, was there a weak root password? Was root ssh login enabled?
It is quite lucky that the attacker was not really experienced and more or less just used the scripts he downloaded somewhere without knowing exactly what they were doing. Otherwise without anything like tripwire this might have gone unnoticed for quite some time.
Why should this be a problem? Even with low voltages a lot of power could be saved, just use a large number of these nanoparticles in parallel and you have a nice source for electrical energy. Connecting them together to get an even higher voltage might be possible as, but is not absolutely neccessary, just think of your average battery which operates around 1.5V. Just think of your physics class: power = voltage * current, so a low voltage does not restrict the power output, although it increases electrical losses.
The only problem so far is the low efficency with energy conversion through the seebeck effect and this might be a step into the right direction.
approach to fighting spam. Your idea will not work. Here is why it won't work. (One or more of the following may apply to your particular idea, and it may have other flaws which used to vary from state to state before a bad federal law was passed.)
( ) Spammers can easily use it to harvest email addresses ( ) Mailing lists and other legitimate email uses would be affected ( ) No one will be able to find the guy or collect the money ( ) It is defenseless against brute force attacks (x) It will stop spam for two weeks and then we'll be stuck with it ( ) Users of email will not put up with it ( ) Microsoft will not put up with it ( ) The police will not put up with it ( ) Requires too much cooperation from spammers (x) Requires immediate total cooperation from everybody at once ( ) Many email users cannot afford to lose business or alienate potential employers ( ) Spammers don't care about invalid addresses in their lists (x) Anyone could anonymously destroy anyone else's career or business
Specifically, your plan fails to account for
( ) Laws expressly prohibiting it (x) Lack of centrally controlling authority for email (x) Open relays in foreign countries ( ) Ease of searching tiny alphanumeric address space of all email addresses ( ) Asshats ( ) Jurisdictional problems ( ) Unpopularity of weird new taxes ( ) Public reluctance to accept weird new forms of money (x) Huge existing software investment in SMTP ( ) Susceptibility of protocols other than SMTP to attack ( ) Willingness of users to install OS patches received by email ( ) Armies of worm riddled broadband-connected Windows boxes ( ) Eternal arms race involved in all filtering approaches ( ) Extreme profitability of spam (x) Joe jobs and/or identity theft ( ) Technically illiterate politicians ( ) Extreme stupidity on the part of people who do business with spammers ( ) Dishonesty on the part of spammers themselves ( ) Bandwidth costs that are unaffected by client filtering ( ) Outlook
and the following philosophical objections may also apply:
(x) Ideas similar to yours are easy to come up with, yet none have ever been shown practical ( ) Any scheme based on opt-out is unacceptable ( ) SMTP headers should not be the subject of legislation ( ) Blacklists suck ( ) Whitelists suck ( ) We should be able to talk about Viagra without being censored ( ) Countermeasures should not involve wire fraud or credit card fraud ( ) Countermeasures should not involve sabotage of public networks (x) Countermeasures must work if phased in gradually ( ) Sending email should be free (x) Why should we have to trust you and your servers? ( ) Incompatiblity with open source or open source licenses ( ) Feel-good measures do nothing to solve the problem ( ) Temporary/one-time email addresses are cumbersome (x) I don't want the government reading my email ( ) Killing them that way is not slow and painful enough
Furthermore, this is what I think about you:
(x) Sorry dude, but I don't think it would work. ( ) This is a stupid idea, and you're a stupid person for suggesting it. ( ) Nice try, assh0le! I'm going to find out where you live and burn your house down!
An important difference between the case and your analogy is that it were not her private pictures.
In my opinion a better offline analogy would be if she was responsible for collecting the school's mail. On the way to the classroom she emptied the school's mailbox and during her lesson some sex advertisement slipped out from that stack of letters.
Suing a teacher for something like that is unbelievable. It ruins your education system in the long term for sure if you have to work in such a climate.
Even without a PhD in physiology I would agree that it burns extra calories. This is however not so hard to achieve, so why should it be a marketing lie? You are certainly right that you have to burn more calories than you consume but why should there be no "magic" thing that increases the amount of burned calories without having so much calories itself? I think this is exactly what is happening here. Lets say the drink contains 50 calories, increases your metabolism to burn 20 extra calories per hour through caffeine, green tea or something else. After three hours this drink has the claimed "negative calorie effect".
This sums up my gentoo experience quite well. It is still running on my small server, the new bash 3.1 breaks my firewall script (firehol), bug report did not help and so I am sitting here and thinking about switching to Ubuntu or a small server distro. I think I might just stop upgrading and only use GLSAs from now on, maybe that is the way to go for someone who does not want to spend time writing bug reports every month.
They managed to get reasonable frame rates with a FPGA board, which is rather slow compared to modern GPUs. A lot of special effects like diffraction are included and don't kill the framerate. This might be a very interesting alternative to more texels/s and shaders. It just looks good as well: http://graphics.cs.uni-sb.de/~woop/rpu/rpu.html
Federalism exists all over Europe. Not exactly in the same form as in the United States but we do have seperate states in our countries. Just look up Spain or Germany as an example.
National ID cards do not automatically need a centralized database, so there is nothing to take over. In my case the record is kept by my city so there is not even a state database.
They definitely increase the amount of effort you need to steal somebodys identity. If you want any personal data you go to a government office of some kind and show your ID. They look at the picture and see that it is you and nobody else. It works nicely against credit card fraud as well. In case a shopkeeper is not sure whether this is really your credit card he just asks you for your ID.
There are definitely arguments for and against national ID but your arguments do not seem to be valid regarding current European policy.
The information content in a 1MB jpeg is much more than a 1MB raw.
It seems some people are just going down the road "RAW, nothing else but RAW..." without thinking about this sentence at all. Compare it with mp3 if you want. Try to squeeze a minute of music into an 1MB wave-file and compare that with a minute of music in an 1MB mp3-file. Which will sound better? If storage space and memory card speed go into the equation at all it will always be better to compress data. This is the point of jpeg, mpeg, mp3...
This is a lot better for heating up food than any other method. A simple isolated wire inside the water container has an efficiency that should be well over 95% and it can heat itself up in seconds. So you are wasting at least 30% just to heat up your water quickly. It is not the best idea to use electricity to heat up things in the first place but this concept is purely nonsense.
Or if you want something smaller than Apache and a little more than just static pages try http://www.lighttpd.net/. It is secure and beats Apache 2 performance wise and the configuration takes only a few minutes. It runs on my small server for months now and is certainly worth a look.
