Quantum Physics Just Got Less Complicated

hweimer Re:How about someone who groks the math, comment? (193 comments)

I just had a brief look at the published version of the paper. Unless you work on fundamental aspects of quantum information theory, the actual implication is that some old debate that took place back in the 90s has been resolved. As others have already pointed out, the relationship between uncertainty relations and wave-particle duality intuitively makes sense, but actually coming up with a mathematical proof that the two concepts are equivalent to each other is certainly a non-trivial amount of work. However, this paper does not significantly change our understanding of quantum physics, nor does it allow us to magically find an efficient way to simulate quantum physics on classical computers. It will also not change the way quantum physics is usually taught, as wave-particle duality basically plays no role there (and uncertainty relations are mostly a side remark).

Also, notice that the paper has been published in Nature Communications. Usually, this means that the paper was rejected by Nature Physics (or any other of the "Nature Something" journals), so the authors sent it there instead (BTDT). So we probably have at least an editor (and maybe some referees) who thought that the paper was not as sexy as the press release seems to imply.

Well, wizards are probably the easiest class to play genoless because Magicbane will absorb almost all the curses from the Ls, and you have more than enough ranged attacks to choose from to deal with the ;s.

NetHack: Still One of the Greatest Games Ever Written

hweimer Re:Nethack needs an upgrade (186 comments)

Nethack needs full multi-user, and an overhaul on the generated story (what there is of it), so that the core process can be daemonized, and users attaching to the system can play against each other.

There's a fork called NetHack 4 that is pretty much identical to vanilla as far as gameplay is concernced, but provides a client-server architecture. While I don't think that NetHack can ever be turned into a massive online game with thousands of players meeting each other, small scale PvP or co-op mode might be doable and actually fun.

Programmer Father Asks: What Gets Little Girls Interested In Science?

hweimer Re:Yeesh (584 comments)

I'm all for removing artificial barriers, but once they are down we're gonna have to accept that maybe girls really do want to be princesses

That's the naturalistic fallacy right there. Little kids really want all sorts of things (like lots of candy, for instance), but this doesn't mean that it's a good idea to let them have their way. If the parents believe that their kid shows a behavior that could lead to a disadvantage later in life, then they have to take action. It's called parenting, by the way.

James Watson's Nobel Prize Goes On Auction This Week

hweimer Re:we ARE different (355 comments)

There is a 15 to 18 point gap [wikipedia.org] in IQ test scores in America between blacks and whites.

There's an obvious difference between such a gap and being mentally retarded.

James Watson's Nobel Prize Goes On Auction This Week

hweimer Re:we ARE different (355 comments)

It tells me that IQ scores are related to other things besides genetics. Of course children who are educated, raised in a stimulating environment, and have years of practice at critical thinking are going to do better at these tests.

Sure, but that runs against the racists' "blacks are genetically stupid" claim.

James Watson's Nobel Prize Goes On Auction This Week

hweimer Re:we ARE different (355 comments)

That Africans have, on average, lower IQs, is a scientific fact

Which only tells you that IQ tests do not measure intelligence. Some people have even reported average scores for sub-Saharan countries that would qualify as mentally retarded in the Western world. This clearly does not make sense as the same group of people tends to do just fine when being raised in a first world country.

'Microsoft Lumia' Will Replace the Nokia Brand

hweimer Re:Not a very exciting name (150 comments)

There is marketing research that shows that people remember words with hard consonants better. So a word like "Nokia" or "Kodak", is in some ways a measurably better brand than a word like "Lumia".

If you only care about people rembering your brand name (and not about the associations that come with it), then "Ebola" would be even better.

If Your Cloud Vendor Goes Out of Business, Are You Ready?

hweimer Re:AWS losing $2 billion a year? (150 comments)

Given the new information, then it doesn't matter. AWS is running at some sort of loss, but the question is why are they running at a loss.

Everyone is running cloud services at a huge loss because prices have been driven down so much that it is simply impossible to run a profitable cloud service. Of course, the companies are doing that to drive their competitors out of the market and profit afterwards by using a combination of price hikes and vendor lock-in effects.

Apple Fixes Shellshock In OS X

hweimer Re:I have an idea (174 comments)

I just tried and successfully passed the variable "_BASH_FUNC_thingy" with the value "my_attack" through my apache web server to a CGI script using a url entered into a browser.

No, you get something like QUERY_STRING="_BASH_FUNC_thingy=my_attack", which is harmless because function definitions inside QUERY_STRING are not being evaluated after the last update.

Apple Fixes Shellshock In OS X

hweimer Re:I have an idea (174 comments)

Unless of course the malefactors know this and stick BASH_FUNC_ in front of their exploit strings.

This won't work because an attacker will only be able to manipulate the content of some environment variable, but not its name. And being able to manipulate arbitrary environment variables has always been equivalent to being able to execute arbitrary code. Think LD_PRELOAD or IFS, for example.

Apple Fixes Shellshock In OS X

hweimer Re:I have an idea (174 comments)

How about releasing a version of bash that has function passing disabled.

People are using this feature and taking it away will break stuff. The latest update (not sure whether Apple already ships it) stores all function definitions with a prefix of BASH_FUNC_, and function definitions are disabled for all variables not starting with the prefix. This allows to retain the feature, but prevents the execution of malicious code at the same time.

Anonymous Peer-review Comments May Spark Legal Battle

hweimer Re:Anonymous public peer review (167 comments)

As I am not a user of the PubPeer platform, I cannot judge if comments meant to attack the reputation of an other due to private disputes commonly occur. Furthermore, such attacks with other motive as pure improvement of scientific publication quality are difficult to spot, because this is what anonymous commenting enables to do.

If somebody presents evidence for image manipulations, then why would you care whether this was posted because someone has an axe to grind?

Anonymous Peer-review Comments May Spark Legal Battle

hweimer Re:Anonymous public peer review (167 comments)

Anonymous review is usual in the peer-review processes of most journals, but these comments are in general non-public or at least reviewed by an editor before publication. Some reviewers choose to do their peer-review work without the cover of anonymity and I encourage this. If you have constructive criticism on the work of an other and can this criticism is well founded, you can very well do it openly.

No, you can't. Most active scientists do not have tenure and therefore openly criticizing the work of a bigwig in the field would be extremely dangerous, even when perfectly justified.

Something like PubPeer is extremely tricky. It's an open door to abuse and for commenter to wash their dirty linen in public.

Can you provide an example of someone using a service like PubPeer to wash dirty linen? I have a hard time to imagine how this could be done, especially if you want others to take your allegations seriously.

When Scientists Give Up

hweimer Re:Easy solution (348 comments)

I wouldn't be surprised to see countries such as BRIC members, EU members, or other countries start trying to woo the best and brightest for economic gains.

I think this focus on the "best and brightest" is actually a part of the problem. Sure, you'll need certain skills to run a research group, but these skills are found in many people and not just in the top of the batch. Beyond a certain point, the individual abilities of a researcher tend to be only weakly correlated with the actual research outcomes. There are many examples of people doing amazing science even though they are generally not considered to be top-notch scientists, even including Nobel laureates.

Science is an inherently risky business, with most scientists not finding out anything really exciting during their entire career and only very few ones will hit something that turns out to be really big. But you cannot possibly know in advance what this next big thing is going to be and who will find it, otherwise this wouldn't be science at all. In such an environment, the best investment strategy is to allocate your funds evenly across as many scientists as possible (I think it was Taleb who showed that). Of course, you have to make sure that each scientist gets enough money to run his or her group, but this optimal strategy is exactly the opposite of the current trend towards mega-chairs involving multiple labs and dozens of grad students and postdocs.

Tox, a Skype Replacement Built On 'Privacy First'

hweimer Re:Mandatory linux 4.3 upgrade (174 comments)

Correct me if I'm wrong but doesn't pulse running at the user level only allow ONE user and system-wide utilization is vehemently discouraged by the developers for SECURITY reasons?

No, it's the other way round: Running PulseAudio as a system daemon (as opposed to the default way of per-user sessions) has security implications.

Distributed File System for Debian-based Road Warriors?

hweimer hweimer writes  |  about 2 years ago

hweimer (709734) writes "I manage a small network which includes some clients that are regularly deployed in locations where there is no or only poor internet access. Currently, local copies of data for these clients are created and merged back more or less manually, which naturally creates all sorts of problems. So I'm looking now for a distributed file system so that each client has always access to a local copy, which is automatically re-synced once it comes back online. Storage space is not critical, nor is obscene read/write performance. An additional requirement is that it has to be included in Debian, at least in the upcoming "wheezy" release. Any recommendations?"

Tablet with root access by default?

All French nuclear reactors deemed unsafe

While there is no need for immediate shutdown, the
agency presses for the problems to be fixed quickly. France gets about 80% of its power from nuclear energy and is a major exporter of nuclear technology."

OpenOffice tops 20% market share in Germany

While Microsoft Office comes out top (72%), open source rival OpenOffice is already installed on 21.5% of all PCs and growing. The authors use a clever method to determine the installed office suites of millions of web users: they look for the availability of characteristic fonts being shipped with the various suites. What surprised me the most is that they found hardly any difference in the numbers for home and business users."

Microsoft to Get Malware Bailout in Germany

Exotic Molecule Observed

hweimer hweimer writes  |  more than 5 years ago

hweimer writes "Researchers at the University of Stuttgart in Germany have observed a molecule based on a completely novel binding mechanism. As reported in Nature (preprint), the binding occurs because one of the two atoms in the molecule has an electron in a Rydberg state, very far from its nucleus. These molecules can only be seen at ultracold temperatures and high atomic densities, and their observation reaffirms fundamental statements of quantum theory."
