  1. Re:And in other news... on Majority of Young American Adults Think Astrology Is a Science · · Score: 1
    Since the NSA was fragrantly violating the rights of the public

    'Fragrant Violation' is attractive young ladies violating speed limits and getting away with it when pulled up by the police. Thinking that when the NSA violate anything, they might do so fragrantly is somehow worse than believing astrology to be a science

  2. So What??? on 23-Year-Old Chess Grandmaster Whips Bill Gates In 71 Seconds · · Score: 5, Insightful

    The definitive example of 'News' is 'Man bites dog'. If Carlsen had established a business empire to rival Microsoft in 71 seconds, that might be news.

  3. Re:WRONG UNITS IDIOT (Pedants' corner now open) on EV Owner Arrested Over 5 Cents Worth of Electricity From School's Outlet · · Score: 2

    1] 1kWatt hour/ hour is 1kWatt, of course.

    2] It is a kWatt, abbreviated kW, not a Killowatt or Kw. The unit Watt is named after a person and all units named after people have an initial capital - and the abbreviation is also a capital. Multipliers of 10^6 or greater are capitalised. multipliers of 10^-3 or less are lower case. 'k' and 'kilo' for 10^3 is the odd one out, being lower case.

    If anyone chooses to criticise the placing of the apostrophe in "Pedant's", bear in mind that if you post here, you will make the apostrophe correctly placed.

  4. Wrong analysis at work on this one on Ask Slashdot: How Do You Deal With Programmers Who Have Not Stayed Current? · · Score: 1

    > I work with a developer who is 10 years my senior, but still doesn't understand how to write concurrent code and cannot be trusted to use a revision control system without causing a mess that somebody else will have to clean up. On top of that, he is really resistant to the idea of code reviews

    This is not a skill set issue. Really it is not.

    This is an attitude and competency problem.

    Added to which, if you start off with the wrong analysis that it is a skill set issue and mix age in with your analysis as a probable root cause, you are likely to start down the road of making damaging assumptions with adverse implications for other employees and devalue perfectly good software engineers unnecessarily

  5. Gut feeling: Centres of charge and mass on Mystery of the Shrunken Proton · · Score: 1

    No idea whether this is garbage or has already been taken into account.

    In large scale orbiting systems, equivalent measurements relating to size are based on centre of masses, where the masses also govern the force controlling the orbit.

    In hydrogen atoms the masses still determine the orbit, but the forces are mediated by the charges rather than by the masses directly as gravity, which may not be in the same place as the masses and may be to some extent free to move in relation to the centre of mass

    Looking at this classically - which is very wrong of me - in both electronic and muonic hydrogen, the centre of charge of both the proton and the electron or muon rotate about a fixed point in much the same way as the centres of mass in a 2 body orbital system move around a fixed point between the centres of mass at distances governed by the ratios of the squares of the masses. But in the atomic system if the mass of the proton and its charge can have different centres, the mass of the proton can remain more nearly in the same place, leaving the proton's centre of charge some freedom to orbit the proton's centre of mass and placing the mass centre of the proton nearer the combined charge centre of the orbiting proton and electron or muon pair.

    Given that the muon is much heavier than the electron, the orbit is smaller thus the combined charge centre of the proton muon pair will be much closer to the centre of mass of the proton. This means that the protons centre of charge always remains closer to the centre of gravity. Thus the centre of gravity of the proton is not needing to move so much in a muonic hydrogen atom

    Or maybe the centres of mass and charge of a proton are separated by a fixed distance and in muonic hydrogen, the mass does not need to swing around so much to accommodate the orbit.

    It would be hell to solve in classical mechanics - never mind quantum mechanics.

    Please arrest me for i too have previously made grossly offensive jokes.

    Do you mean you want the state to round up all Anonymous Cowards such as yourself - or are you just hiding behind anonymity?

  7. Too much control agenda on UK Man Arrested For Offensive Joke Posted On Facebook · · Score: 5, Insightful

    It is totally lacking in taste, it is offensive, if the first post is accurate.

    The appropriate response would be to ignore it. However, in the modern UK, there is a demand to control too much of what people say and think. To me that is far more disturbing than the joke itself.

  8. Re:It's Just Gigawatts on Germany Sets New Solar Power Record · · Score: 1

    As I see it, it is unfamiliarity with several concepts. In general, people will be much more comfortable with understanding Horsepower as a rate of delivery of work and will probably have a better understanding of Horsepower than Watts in terms of meaning, quite aside from the question of the magnitudes. I doubt that the majority know that Horsepower and Watts represent the same type of quantity in the way that metres and feet do. But even when people understand Horsepower, they are mostly stumped on relating it to energy - only remembering that it was something dealt with in an otherwise forgotten physics lesson. Journalists are universally flummoxed. Having said that, I am surprised it passed muster for Slashdot.

  9. Inappropriate media on Getting the Latest Rover To Mars · · Score: 1

    Isn't there a write up somewhere? Wouldn't it be better to link to a write up? I don't want to spend 4m19s watching some dumb video with sound in space and fancy graphics. Spoken narrative is too slow. A write up and a diagram or 2 is enough to convey principles, which is what interests me.

  10. Re:How did they do it? on Marking 125 Years Since the Great Gauge Change · · Score: 1

    I am guessing, but I think it was a long time in preparation. With the UK broad gauge, the difference in gauges was large enough that track could be laid in mixed gauge, so the actual changeover could be years of dual gauge operation. For the Southern US, the gauges were too close to permit mixed gauge, I would think. An easy way to do a quick change would be to spike the sleepers [US = ties] on one side only left and right on alternate sleepers when laying track to the broader gauge. Gauge would be held by stretcher bars every few sleepers. On changeover day, the stretcher bars could be taken out and the left and right rails complete with sleepers slewed together and the unspiked sides of the sleepers spiked to the new gauge.

  12. Re:Impossible on Shakespeare In Klingon? · · Score: 1

    But Shakespeare has well defined meaning to a considerable level of sophistication. The way to do it is to extend the language logically from what is already available and where this is not enough, invent more Klingon to express the concepts. Done well, this project has great potential to develop the Klingon language into something fully functional. Not that there is much point, of course.

  14. This is just piffle. on Robust Timing Over the Internet · · Score: 1

    NTP has its limitations and to me the miracle is that it is as good as it is, given the lack of promises concerning packet delivery in a TCP/IP network [No guarantee on route, latency or even delivery]. If you need something more accurate, then use GPS as already suggested or one of the atomic clock backed radio services around the world and calibrate for transmission distances, which is a consistent correction for any location. This will take accuracy close to the theoretical limits and is potentially available cheaply enough that the cost should not be a bar to any application where this sort of accuracy really is justified. I just cannot see any point whatsoever in trying to do this over the internet when you cannot hope to meet the accuracy of existing means.

  15. Socratic evidence gathering? Hah! on College Police Think Using Linux Is Suspicious Behavior · · Score: 1

    Particularly when gathering evidence, police are trained to do so carefully and pedantically in a Socratic way.

    Socratic way: Decide who you think is guilty and selectively look for the evidence which supports that position. Is that the Socratic Method you mean? because this is all I have ever seen police do by way of investigation.

  17. Re:I was going to post... on London Police Seek To Install CCTV In Pubs · · Score: 1

    Timothy, why do you feel the need to misrepresent every story about the UK in the worst possible light? Did you even read the article in question?

    Perhaps you should. The police aren't installing CCTV cameras in pubs. One police chief is recommending to the licensing board that grants licences to pubs that they require new licensees to fit CCTV.

    Gordon, they had a jolly good try at doing it.

    Now - here's the important bit - are you paying attention? They were told that they couldn't do that. Let's just say that again to make sure you've got it - the police were told that they could not ask the licensing board to make installing CCTV a condition of the licence.
    That is the interesting bit, it was the Office of the Information Commissioner who stopped them. Now we need to keep our eyes open to see what happens there.

    It's called literacy, Timothy. You should try it.
    I would say it is vigilance, not a lack of literacy

    Through rose tinted spectacles, it could be that MS might only plan use this patent to stop anyone else doing it - for example by providing MS with a cause for action against anyone providing a root kit to do the same - and maybe providing a cause for action against anyone advertising in that way. I would hope that this is what this is about.

  21. Re:A scary story related to this question on Should Students Be Taught With or Without an IDE? · · Score: 5, Interesting
    After digging further it dawned on me that the root of the problem was that these students had never even heard of a linker, had only the vaguest idea what a compiler was, and weren't sure how the editor was different from the compiler. They were quite certain that single-stepping through code made use of the compiler, though.

    Yes, all too familiar. When I teach C, lesson 1 is Preprocess, Compile, Assemble, Link. Then we do 'Hello World' with notepad, compiling by stages from the CLI, looking at all of the intermediate files. Only after that do we talk about C programming.

    The benefit is that from the outset, everyone understands the process, and from the outset, if something doesn't work, you can talk about did the compiler fail or the linker - which you have no meaningful basis to do without explaining the process.

    The problem wth doing 'Hello World' first is that learning a programming language is like climbing glass mountain. There is so much to learn before you can do anything useful, so conventionally, teachers are very tempted to miss things out. The thing you can afford to miss out is the IDE, going through the Preprocess Compile Assemble and Link process is far more essential. By setting that scene, your students have a context against which to understand everything else.

    Trust me it works. With groups of 3 on a 3 day course, after 1.5 days we do a Yourdon analysis of the mastermind game [see this if you don't know what it is - we don't do graphics, we do it with numbers on the CLI], then we split it into 3 modules and each student codes a module. Then they share their object modules NOT the C code, they link them and we always get a working program either first time or after 20 mins.
