If you're interested in a MSC online and don't mind if it's from a UK university, you might want to check out the University of Liverpool. I think they will accept you on this one. Price was around 18,000 GBP 4 years ago. Some modules are a breeze but others are a PITA; the modules involving group work can be an interesting experience or a really painful one, depending on your group. Their collaboration tools were message boards and crappy Java-based chats and whiteboards; a few fellow students couldn't use voice chat or better collaboration tools because of Internet censorship in their countries, and some other students were rather incompetent. Once you start a module, you're committed to turn out weekly assignments for eight consecutive weeks. They claim you can complete it dedicating between 10 and 20 hours a week, but prepare to work more if you're unlucky.

So I'm not exactly selling it but if you're interested don't be put off; my experience is anecdotal and their website looks pretty different now, everything might have changed. Ask around if you can (I think they have a forum on LinkedIn).

A distributed Javascript project has been running for years here:

The risk is imminent that these methods are as much scam as most previous methods, however well meant they may be.

For a really nice overview and analysis of electronic mosquito repellents, please see http://eprints.liv.ac.uk/665/1/Enyati_electronic_mosquito_repellents.pdf

Here is the summary:

"Electronic mosquito repellents for preventing mosquito bites and malaria infection
Malaria is a major health problem that particularly affects people living in sub-Saharan Africa and other tropical parts of the world. It
often causes considerable morbidity and mortality especially in children under ve. It is transmitted by mosquito bites from infected
female mosquitoes. Several strategies and approaches are available for preventing mosquito bites and malaria infection, including
repellents, and these approaches will be considered by those living in affected areas and by travellers to areas where there is high risk
of infection. Electronic mosquito repellents (EMRs) are designed to repel female mosquitoes by emitting high-pitched sounds almost
inaudible to the human ear. EMRs are claimed by their manufacturers to be effective in repelling mosquitoes and preventing disease.
No randomized controlled trials were found, but 10 eld studies looking at the number of mosquitoes caught on the bare body parts
of humans were assessed. These studies were conducted in various parts of the world with different species of mosquitoes and were
controlled for factors such as locality and timing. One study used just one observer with seven observations, while the highest assessment
included 18 observers with 324 observations. There was no evidence in the eld studies to support any repelling effects of EMRs, hence
no evidence to support their promotion or use. Future randomized controlled trials are not proposed as there was no suggestion in the
eld studies that EMRs show any promise as a preventive measure against malaria."

Gates uses his money for good research. Still, that article does show that Gates needs to have several independent evaluators, unknown to each other, too.

The algorithm used to do this sounds like it may be this one: BBP Formula.

This is also the same algorithm used in the browser based Distributed Pi project.

The only difference between using the BBP formula to generate Pi or Pi^2 is the use of different constants.

you can always use iptables and hashlimit module to limit the number of connections to port 22 as well as using sshdfilter

AFAIK carbohydrates in any form are not required nutrients. At least, there are plenty of documented cases of people living long, happy, healthy, productive lives without ever tasting them. The Inuit, for instance, used to regard plants as unfit for human consumption, and would never touch them unless they were starving. OTOH there is evidence that excessive carbohydrates (or possibly the wrong kind) can gradually bring about insulin resistance, obesity, and eventually diabetes.

The best comment I've ever read on so-called "paleo" diets came from Alan Aragon:

"Paleo nuts will insist that ancestral eating patterns were optimal. This is just as speculative as insisting that their hygiene habits were optimal, too."

You might be interested in some actual historical review on this topic as well: http://pcwww.liv.ac.uk/~gowlett/GowlettCJNE_13_03_02.pdf

Again, there is ample evidence to show that some people (as in many thousands) have consumed well under 2000 calories a month for decades, in the form of carbohydrates, while doing hard physical work - and wound up grossly obese. Just as others (usually much wealthier) have eaten far more than 2000 calories a day for years, while doing little or no physical work, and remained lean and fit.

Body weight is determined by energy balance (calories in vs. calories burned). Are there some people so small that 2000 calorie diets are way over budget, even with exercise? You bet. That doesn't change the equation. Here's the state of research on the topic:

http://www.nhlbi.nih.gov/health/public/heart/obesity/wecan/learn-it/balance.htm

Some things in nutrition science are unknown or controversial. This isn't -- except among quacks and people with books to sell.

As far as carb restriction and weight loss, you should know the recent research on the topic shows no difference between carb restriction and non-carb-restriction, once energy balance is controlled.

Consider, if it's not too challenging, the possibility that human bodies treat different nutrients in different ways. Ask yourself why - if constant weight can be maintained only by making sure that "energy in equals energy out" - most human beings (and other animals) keep their weight within a pound or two for decades on end.

It seems to me you're confusing "simple" with "easy". Body weight and energy balance are indeed simple things. Keeping energy balance where you want it isn't. In fact, even among people who count calories, studies say there's a tendency to grossly underestimate calories consumed (20% or more).

Yes, that's right - join the bulk of the scientific, medical, and political establishments - and the big food manufacturers who fund them - and blame the victims.

And yet you swallow the junk nutrition myths from people with books to sell you hook, line and sinker.

You seem to have little understanding of scientific research, disclosure of bias and how to deal with it, etc.

SSHDFilter may help in this regard. Everyone should be taking steps to limit brute-force ssh attacks even without this current issue.

"They" won't "ban" everything that is misused by drunken children. What they will do to some extent is license things where the risk of people carrying them outweighs the benefit.

Ultra high power laser pointers are a special category - they can blind someone permanently from a distance but there is no legitimate reason to carry one in your pocket. Thus carrying them without a license should be illegal and people that break the law should be punished. The rationale for that is the otherwise kids will shine them in people's eyes either deliberately or accidentally (maybe they were aiming at balloons) permanently blind them.

From what I've read, there are people that need these things for their jobs, and they will get a license to have one and training on how to use it.

In the UK there is similar legislation recommended
http://www.liv.ac.uk/radiation/pdf/laserpointers.pdf
The HPA considers the professional use of a Class 1 or Class 2 laser pointer as a training aid in the workplace to be justified, and regards these Classes of laser product as being generally adequate for such use. The use of Class 3R laser pointers up to 5 mW may be justified for some applications in the workplace where the user has received adequate training.

The HPA advises that the sale of laser products to the general public for use as laser pointers should be restricted to Class 1 or Class 2 devices which should be classified in accordance with the requirements of the current British Standard and should be sold with sufficient accompanying information to enable the user to operate the product in a safe manner. Toys should be Class 1 or of such low output that they do not need to be classified.

After seeking advice from NRPB (now the Radiation Protection Division of the HPA) the Department of Trade and Industry urged Trading Standards Authorities to use their existing powers under the General Product Safety Regulations 2005 5 to remove laser pointers of a Class higher than Class 2 (as defined in the British Standard) from the general market. Such devices are too powerful for general use as laser pointers and present an unacceptable risk in the hands of the consumer because they may cause eye injury in normal reasonably foreseeable use.

Now lots of other things are potentially lethal but are mostly used legitimately. Cars for example. And at least in America guns are protected by the Second Amendment.

High power laser pointers seem to be popular with idiots who use them for tricks in an unsafe way - other posters have talked about kids zapping drivers at stop lights and TFA talks about people shining them at pilots in planes. I once went to a computer user group meeting at a pub where someone had a HeNe laser and was shining out at people on the street. Later on he actually said it would cause blindness if you looked into it. Unbelievable.

I think for that reason they should be controlled by a license. If you need one for your job, apply for a license. If not, expect a prison term if you carry one around in most countries.

This isn't a new information at all. This is just a repeat of other studies done using the same methods. For example, this one was published in 2004: http://www.liv.ac.uk/evolpsyc/2004_face_ovulation. pdf

Get this and your ssh brute force attack worries will be over. They're only popular because ssh tends not to block repeated attempts by default, and many other avenues have been closed to the crackers. So make sure you block this particular route.

I agree, as much as I hate Microsoft or some of its very bad software, here at the University of Liverpool Bill Gate's fundation has given a huge amount of money ( $50.7 million ) to improve research in Malaria disease.

A lot of people could be pissed of about Microsoft's practices but, it would be nice to compare the 10 first billionaries from Forbes (from which the 3rd one is a Mexican [as I am BTW]) and see what is the amount of money these people has donated. It does not matter if the donations are tax deductible or whatever, the only thing that matters is that, from the *corporate-evil* borg, I believe Bill Gates is one of the less evil around there.

Personally, I admire him from what he is doing, and from his vision. And for all of the people that says he is not a true geek or whatever, I believe he was more "geek" as more than the half of geeks that consider themselves "geeks" nowadays. If you think it like that, a lot of people that program in kiddos languages like Python, Pearl and javascript/html would explode at the idea of programming a programming-language at an emulator.

Just to add to the previous comments:

I've just spent three years doing an online masters from the University of Liverpool. Trust me it's a real place !

And yes they do make you work. Try several hours a day, 7 days a week for best part of 3 years. This was much harder than my undergraduate degree in Mathematics, as you would expect from a Masters course.

See http://www.liv.ac.uk/ for info, click the 'Online Masters Course' box if you're interested.

• Choose one offered by an established University with a good reputation.
• Make sure the degree you will be awarded is identical to those issued to traditional students.

Indians "with feathers", ie Native American Indians, did have the concept of zero.

sshdfilter blocks the frequent brute force attacks on ssh daemons, it does this by directly reading the sshd logging output and generating iptables rules, the process can be quick enough to block an attack before they get a chance to enter any password at all.

I recently stumbled upon sshdfilter. It analyzes sshd output in real time by running sshd in with the -e option and adds attempts to login with invalid usernames to an iptables chain to drop all packets from that host. I've only been running it for a week or so, but it seems to be working well.

Seems like a similar idea to DenyHosts, just a different implementation.

People keep saying Novell is dead. I keep on telling them that Netware is little more than glorified policies, and it's questions like this that reenforce my view.

Netware is a great product for controlling users. Netware is a great product (fantastic, in fact) for application role outs over a network, on demand
Netware is also a fantastic 'suite' of programs.

My uni, clearly, uses Novell.

Sometimes it's easier to user what your vendor supplies than it is to craft your own. I say this, am I am 'the' () foremost interoperativity bloke, hacking qmail, imap courier, apache and sqmail into a bespoke single login system. The problem with my usual apporach, is although it's exactly what I want, it takes time. My time is better spent on other issues, and therefore, I rely on vendors to do the best they can.

Has anyone seem Mandrake/Madrivalyswhatever's server install? Advx, their high-performance apache install is fantastic.

The students have to take out loans now - most end up with debts of 10K pounds or more. Top-up fees of 3K per year are also being introduced. Although there were plans to scrap that and have a "pot" where everyone would be given a grant, and require to pay the money back once they found a job.

The student population of Liverpool is estimated to be 50,000 Manchester also has a student population of 65,000. So you can guess that the student population brings in millions of pounds to the area.

Changing the subject, minimum wage of £5/hr sounds pretty goood!

But you have to include the cost of living. I could rent a flat in Ontario for 750 Canadian dollars (property tax, electricity and water included).

In the UK, the monthly rent for a good two bedroom flat in Edinburgh is around 450 pounds, Liverpool is 650 pounds, and Brighton 850 pounds. Council tax is 1000 pounds/year, Electricity is 1000 pounds/year, and food is 40 pounds/week. And landlords typically require two months rent in advance. And a car will cost another 3000 pounds/year.

To rent your own place in the South, you would need at least 20K/year. If you were to share a flat with another person, you could just about break even. A minimum wage job, would only bring in 10K/year at 40 hours/week (most of which are part-time anyway).

There are many stories of people taking jobs in the London area, and leaving again once they find that they are actually loosing money by staying there.

I get to see lots of bad/stupid driving everyday, all day. People take their driving test, then just do what they want when they've passed. The instructors don't even seem to correct bad behaviour when they are training people. It seems that automatic "cars" as portrayed in Minority Report or I Robot will be the only way to go if the number of vehicles is allowed to grow unchecked.
I am all in favour of an inbuilt electronic system much like the Tachographs we have in large goods vehicles in Europe. It would have to be electronic for car use, because you wouldn't be able to trust the average car driver to change the paper disks every day.
For those who don't know, tachographs record speed against time and also rest periods. So if the vehicle has moved, that fact is recorded. In an electronic version, the device would record speed in much the same way, but would be impervious to user intervention. That way, if there were an accident, the device could be read via a scanner and report the actual conditions at the time of the crash. Also, it would require the driver to assume responsibility for the way they drive, which is something that seems to have been forgotten. Any time law enforcement had occasion to stop a vehicle, they would be able to see the recent driving history of that vehicle and prosecute infringments as neccessary. This is not big brother, this is common sense. No location details need to be recorded. Combined with sensors on the steering wheel to determine blood alcohol levels (which would disable the car if you were over the limit) a system like this would require people to pay attention to what they were doing while driving.
The car these days is no longer simply a transportation device, it has become a fashion item / portable entertainment system, and the skill of the drivers has decreased as a result. Most people I see have difficulty reversing, staying in a designated lane or even steering ! I can always tell when some people have accelerated, because the car veers to the right ?!
There was a funny experiment shown on tv recently, where, on a perfectly straight piece of road, they painted a "wiggle" in the white centre lane markings. Then they filmed the results. Most of the cars driving past actually swerved to follow the line of the "wiggle" !
In brief, if people are going to reject public transport (where the driver is more highly qualified) then they must be forced into compliance. The car is not a toy, it is a machine, and a large, heavy, deadly one at that.

Check your paws guys (yes, I know women read /. too, but this one is a study on males). This study correlates depression with the relative length of the ring finger to your height. It then correlates this to prenatal testosterone, prenatal testosterone to more growth of the right hemisphere of the brain (at the expense of the left), and therefore to some aspects of intelligence (susceptability to autism, etc).

Well, I am an archaeologist ... and every-time I excavate a grave I deal with serious moral problems. But archaeology today (real one, not fancy stories like this one) is mainly about saving graves from bulldozers. The only dilemma we face in reality is weather ancient ground will be excavated by archaeologist (which treat and study human remains with respect and share the knowledge) or destroyed by capital driven bulldozers, preparing ground for new shopping mall.

However, I do believe that right of indigenous societies to leave their dead undisturbed -- which in consequence means that they have right to their own past, not "scientific" one -- should be respected.

Interesting, this story reminded me of the Jacquard Loom. The Jacquard Loom used punch cards to control the designs it embroidered into clothing material.

Herman Hollerith was hired to automate the 1890 US Census because it was apparent that information processing techniques simply weren't keeping up with the burgeoning US population. When it came time to do the 1890 census, they weren't yet finished processing teh previous census.

When Hollerith encountered the Jacquard loom and realized the significance of its punch card method he realized that he had stumbled on a method for automating the input of information for later processing.

He then took his information processing techniques and founded the Hollerith Corporation. This company later underwent a name change and eventually came to dominate in the computing field.

I've heard (no, I don't have actual links to articles) that 10% of peak performance on a cluster is considered really good.

Sounds like Cray marketing articles. For example, Daniel Katz at JPL wrote in 1997:

it is possible to construct a 16-node machine with a theoretical peak performance of 3.2 GFlop/s and a typical sustained performance of 1.2 GFlop/s

The current Beowulf cluster can deliver a theoretical peak performance of about 100 Gigaflops (billions of floating point operations per second) and has been observed to deliver about 60 Gigaflops.

The observed performance was based on LU decomposition.

For sustained/peak of about 60%.

I have no doubt that one could find problems where a Beowulf cluster has 10% efficiency, but there are real many problems that are good to go on a cluster. And even if you only got 10% it would be worth it if the cluster cost 5% of what a vector computer costs. Not to mention that performance/$ on commodity hardware increases by a factor of 2 every 12-24 months. It takes years to develop a supercomputer, and they are stuck at their level of technology for several years since they are so expensive to redesign.

I wonder, is US Goverment the only one in the world keeping such stupid laws or other countries have same or similar stupidy in place?

It's not just us (US), it's endemic to all bureacracies. It's quite possibly caused by the toxic side effects of Administratium.

If anything, the script looks vaguely like handwritten gaelic latinoid script (Think book of Kells), but much less ornamented, and more like "day-to-day" writing. This script diverged from latin script in the 0-400A.D. period, but evolved and persisted until the 20th century, when Irish was standardised into contemporary latin script.

Irish dialects make extensive use "shebhus" and "urus" - aspirates and eclipses, indicated by accents in the old scripts - sebhus were usually dots above the letter, but could be diamonds, for example [modern script, just put a h in instead]. I note the presence of diamonds above some letters, and the apple-command-signs could conceivably be uru-forms?

The Irish also have set precedents of inventing their own alphabets: In addition to their own latin variant, they had the ancient ogham script, which is just plain wierd, originally written along corners of rocks and cut wood by notching them. Some people think it's just a A.D.-era encoding of a latin script, but many Irish people think that it's much older, and that just because one finds latin and old-irish inscriptions in Ogham, doesn't mean it was first used for them, since one can quite conceivably phonetically transcribe english into cyrillic or greek or japanese, for example. Plus, ogham looks like random scratches on rocks to people who don't know about it, and plus, most ogham is beleived to have been written on wooden rods- "the poet's slats" in ancient irish literature, which would be long-decayed by now. "Modern" standard Ogham even has a unicode table entry :-)

but all that's well known and would have been eliminated already, plus few of the words look particularly gaelic.

However, there are little known, mainly lost, and very strange "secret" Irishoid languages - e.g. one called "Shelta" that is the language that some members of the "Traveller" / "Tinker" racially distinct population in Ireland once spoke. [the page I've linked to looks to be 7/10ths made-up, I'm afraid, but, being in Ireland, I can confirm that travellers did have their own secret language, that they jealously guarded.] Travellers/Tinkers were somewhat like Romany gypsies in other countries in lifestyle, but unrelated - maybe it's shelta-in-irish-latinate-like-script.

Such people would have been mad into their own astrology, which would probably have the old irish constellations rather than known ones [It is known that there were old Irish traveller constellations, just not what they were :-)] - If one were an Irish tinker, inventing one's own script for your own mainly-illiterate community's language, it would probably end up looking like "hitherto-unknown-language-in-gaelic-like-script." .

Shelta isn't the only "secret" Irish language - Medieval guilds in Irish and Scottish* cities often had their own entire languages to guard their secrets - The dublin stonemason's seems to have been a dialect of Shelta with viking influences, for example.

*Ireland and scotland were pretty much the same until the tenth century - Confusingly, before the tenth century, someone saying "Scotia" probably meant Ireland.

Because for mission critical applications the US Department of Defence consider C, C++ and Java to suck.

See here for a brief history about why the US Department of Defence found that they were using 450 odd languages and needed to standardise on one common one that did everything right.

They produced a specification of what the language should do and found that nothing out there did what was required well enough. So a competition was born and ADA was the language that won it.

Question: Is there an ordering of the n cities such that the value sum from i=1 to n-1 dpi(i),pi(i+1)+dpi(n),pi(1) is no more than B?

Comments: In effect what this problem is asking is whether there is a tour of the given collection of cities that visits each city exactly once and takes up total distance no more than B. There is a huge volume of literature concerning approximation methods, search heuristics, special case methods, etc for this very well studied problem. A bibliography has been compiled.

There's plenty more where they came from. Most distrbutions come with a lot of these things anyway. These are mainly analysis or document tools, there's plenty of other things for both these areas and any other which plenty of other posters have shown. I've written a little guide for my local group. Some of it's out of date (and some of it's wrong but I have better things to fix) but it does have a list of common tools we use. And, of course, SAL is a pretty comprehensive database of unix tools. HTH.

You play on a simple field (often times an 80x25 terminal window). Your intreped hero has no weapons (sometimes he has a single shot sonic screwdriver) and if any robot touches him he dies. You can only kill the robots by making them run into each other (where they'll leave piles of debris behind--and running into debris is also deadly for the robots!). The robots are very stupid, they always head in a bee-line to the player (at least as much as they can being constrained to moving in ordinal directions). Your hero's primary weapon is a teleporter that randomly teleports him to somewhere else in the playing field (including occasionally next to a robot). The game is over when a robot touches the player (usually when you teleport in right next to a robot). A somewhat feature lacking version can be compiled from here:
