  1. keep 2 languages on Managing Parallel Development in Two Languages? · · Score: 1

    i have experience in similar math-driven environments so can offer relevant thoughts.

    a math-centric or faff-minimising prototyping environment is crucial whilst constructing the math models which you'll later be putting into Production. you want to absolutely minimise the Drag of the tool on the thought process. you can use MatLab or Excel or a piece of paper.

    then take the result as being the Specification (Logical) which will feed into your development. your Production-ready code's particular Physical architecture will be influenced by that nasty thing called reality: performance, time/functionality tradeoffs, clients' hardware, legal requirements, that sort of thing.



    you can use C++ if you want but i would advise against it unless you have strong historical/legacy lockins. for Maths work, Python's "NumPy" library actually runs faster than the standard C++ libraries (plus it can near-transparently use C/C++ libraries), and you avoid 99% of the time-wasting faff that C++ forces on the coders. so you develop several orders of magnitude faster. a lovely lovely language which slots straight into your mathematical environment.

    >I think that one of the most interesting parts of this new iMac is the fact that it has air holes in the top of it so that the hot air can rise out. Now why hasn't anyone else thought of that?

    :) It's not a new concept, but yeah, not one very often used.
    Essentially, it's a tradeoff between the heat benefits when switched on and the dust problems when switched off.


    Historical Note:
    Silent convection-driven cooling was one of the design goals of the very first macs: they had no fans at all.

    When fans finally became necessary, for a while you could buy a "Mac Hat" which was like a turbine tail/funnel you put on top of a mac with the fan unplugged: this passively created the extra airflow required.

    The growth in chip heat has pretty much killed the fanless idea (the mid90s performas drew a MAXIMUM of 5 watts... not the chip, the whole machine), but the Apple Engineers seem to keep it in mind. The Cube, for example, blew air up a central column.

    ps Sorry, forgot to say why: the reason for the customs faff is they'll stick you an extra 17.5% as you walk in the door IF it's "new", which sharply reduces your discount. The remainder of the discount is due to the UK's stalwart protection of monopoly/oligopoly premia, the reason for e.g. Renault historically earning 50% of its profits out of the UK despite making only 10-15% of its sales there by unit.

    I think Daneurysm (great eddress btw) is being kind to the human race here. In my experience, most humans' morals, ethics, and what you had regarded as their character, goes out the window when money becomes an issue, either in the sense of stress/need to pay, or in the sense of opportunity. I've lost what was my best friend to opportunity, I've been shafted by people seeking to skive out from their contractual obligations in a wide variety of circumstances.

    My advice: if you think there's ANY possibility of the business ever needing rigorous professionalism, make an upfront EXPLICIT (written) agreement that the professional relationship can not endanger the personal one, and that as originator of the professional environment, ANY nonperfection in your eyes requires shouting, which you can't do to a girlfriend, so that the THIRD time you get stressed by her behaviour, it's time to hire a third party. Is that the way it needs to be? No. Is taking such an extreme possibleposition a good idea in such a sensitive environment with such potentially serious repercussions for the rest of your life: emotionally, professionally, financially?

    Hmm, institutionalised corruption was a further wrinkle I didn't think of. Check out the last few paras of this thread for a complementary look at other hidden international exposures.

  18. Hang on, that's a different topic on Is Security Holding VoIP Back? · · Score: 1

    Your post (and outraged indignation :) confused me unti I realised we were talking about 2 completely different topics.
    You are referring to people being able to pick up a phone and talk to someone via PSTN. And you are absolutely right. Both PSTN and VoIP (or CDMA or GSM or blahblah) are usable by any user; the underlying transport technology is utterly irrelevant to them and usually unknown by them: it is "transparent" technology in the old now-near-forgotten UI terms.

    But that's not this discussion's topic.
    The parent slashdot topic was focussed on (Lack of) Security, not the end-user interface -- the ability to step behind the curtain, as it were, and access someone else's phone call. So my post wasn't referring to Joe Public trying to sort his evening's pizza, but rather Fred Blackhat trying to listen in on the call ("Ah HA! Pepperoni... we have him now...").

    The key thing I was trying to point up was that a MAJOR difference in the practical security of VoIP vs PSTN is not technical, but cultural/sociological: the motivation of the people with VoIP-cracking skills is much less likely to be confined to professional work than those with PSTN/POTS/CDMA/GSM skills.
    To put it another way, the difference between a gun and a murder is motive.

    The average trained telecoms engineer or even technician will have trained in a formal environment for several years to gain these skills, and will overwhelmingly tend to be using them in a normal professional environment, and as such will tend to have a normal social skillset and social life. Few telecoms technicians believe they will gain professional cred by cracking a network -- most skilled ones recognise that any engineer can do it, it's not hard for them (remember the bored "so what?" response to the gosh-wow announcement by that Israeli uni crew that they'd "cracked" GSM?).

    In the IP world though, you've got the script kiddie syndrome. Find a crack for the sake of peer props, then propagate that crack. Fred Blackhat no longer needs 4 years training and expensive kit, he can just hang around on some IRC channels and wait for the current crack.

    And yes, this risk only applies to the portions of the traffic that go by public networks. But it's still there and Joe Public can't know which calls are all-private and which travel on public networks. And don't underestimate your exposure. I once got a direct email in London from an unknown student quoting stuff from a private email to some friends in the Baltics. I traced it back and then started wandering round some networks and worked out a pool hall where me and these friends had killed some time surfing while waiting for a table one night, had had network access provided by an extension of the uni network, one machine from the CS dept had briefly served double duty and now acted as a gateway between the uni and the pool hall (among many others). To cut a long story short, due to a brief period of technical shortcut followed by unexpectedly explosive growth in a commercial extension of the university's underused top-quality infrastructure, the uni's CS students can monitor & intercept a great deal of "commercial" traffic in that region. OK, they're still at script kiddy mentality of showing off. But in future?

    In assessing your own practical risk, you have to take a position on how many silent timebombs you believe are sitting around your own country, waiting for a good reason to be used.

    And you might like to hesitate a moment and reflect that your own IP traffic is increasingly likely to be routed via a low-cost high-tech country sometimes, according to the whims of the market... Remember where DarkAvenger came from?

  19. 1/ Eyes 2/ Brain on Protecting and Preserving Your Vision? · · Score: 1
    You complain about fatigue from coding(?) for lengthy periods. There are 2 things that jump out at me from this:
    1. Eye fatigue
    2. Brain fatigue

    1. Eye Fatigue: assuming you've done sensible things like vary the screen contrast and whitepoint to match your surroundings, the most common problem is slow screen refresh. And different people eyes "refresh" at different rates. A good quick test: when you're at the movies and watching a panning shot move across scenery, do your eyes swim in almost-pain from the inability to focus? You have fast-refreshing eyes. Set your screen to refresh to a minimum of 85Hz, 100 or 120 if it can. The difference can be felt immediately in a reduced level of tension around the eyes and neck.

    2. Brain Fatigue: if you're coding creatively, such as doing new work, you are stressing your brain. The brain chews a surprising amount of energy and also particular nutrients, especially fats (essential fatty acids & oils). Fish oils (superior to flax/linseed substitutes) will tend to improve clarity of thinking (and also reduce dyslexia and antisocial behaviour, interestingly). But to improve mental stamina, take L-Glutamine combined with L-Tyrosine and L-Phenylalinine. These are the primary amino acids used by the brain when thinking, and supplementing your intake will sharply lift your mental stamina and reduce your stress/fatigue levels associated with mental work.

    Chromium is key to the body's ability to regulate blood sugar, and is disappearing from the normal diet due to modern intensive farming techniques. A supplement of chromium will tend to stabilise your blood sugar variations, and over time tends to reduce the symptoms of diabetes. Try 200mg/day of chromium picolinate to start, vary the dose up or down depending on how well you respond to it. It IS a metal though, not a water-soluble vitamin, so don't take silly doses -- you don't need that much.

  23. Re:One suggestion... on Cooking with the Internet? · · Score: 2, Interesting

    Depends on the food being cooked and how stupidly you cook it. Heat breaks down vitamins, true; but it also breaks down the compounds and chemical bonds which lock the vitamins and minerals away from easy digestion. It's a bit of a race condition as regards to where you catch the trade-off of increased digestibility versus less left to digest. And it varies by food too, for example potatoes tend to just keep on increasing in digestible vitamin content the longer you cook them, but the higher their glycaemic index grows too...
    Humans' digestion systems most closely matches that of scavengers, and you'll note that a great many delicacies and "ideal" cooking or food preparation techniques essentially involve food rotting, commencing a breakdown of chemical bonds. Examples: blue cheese, meat hung for a week, old wine. Heat proxies this process.
