  1. Apple ][e : BASIC and assembly, self taught at 12 on How Did You Learn How To Program? · · Score: 1

    First with Apple ][e , self taught by books at 12yo:

    In the order:
    - Applesoft BASIC , spaghetti code
    - 6502 Assembly, no assembler, spaghetti code
    - 6502 Assembly with LISA assembler, still spaghetti code

    Then on PC, with school courses at 18:

    - Turbo Pascal: the revelation of structured programming

    Later: OO programming (by courses and books), and then many languages self taught.

    What I see is that I needed a good mentor to get rid of bad habits and silly programming techniques.
    Self taught with language reference books is not enought to do well.

  2. Re:Sensationalist summary on French Police End Missing Persons Searches, Suggest Using Facebook · · Score: 4, Informative

    Yes, translation is:

    Allows you to search for a missing person, your family, to renew relations with her. Does not apply to missing persons in alarming conditions suspicious or criminal.

    So this kind of search is no longer available with the state help.
    Ok... Is it really worth a story on /. ?

  3. Re:Still not good enough! on New Thunderbolt Revision Features 20 Gbps Throughput, 4K Video Support · · Score: 1

    This isn't about "some people say" or my eyes, this is the result of an experiment, which conclude that 72 fps is the maximum rate that enhances user experience.

    See http://en.wikipedia.org/wiki/Frame_rate, about 72p (yes, citation needed, I know).

    If you maid an experiment (double blind conditions) that shows that you can tell the difference between 72fdp and 120fps, you should report it, please.

  4. Re:Still not good enough! on New Thunderbolt Revision Features 20 Gbps Throughput, 4K Video Support · · Score: 2

    3D or High Framerate: 120 fps

    Sure, you can drop the framerates, but then expect to have a headache viewing 3D.

    60 fps only are required for "3D" at 30fps

    72 fps is the maximum rate that enhances user experience, above the eyes and brain don't feel there's a difference (for 2D display)

    20 Gbps are enough for this.

  5. Always antialiasing ? Or use a trick ? on New Camera Sensor Filter Allows Twice As Much Light · · Score: 1

    Does anyone know some discretization or quantization technique which doesn't need antialiasing ?

    I'm thinking of a non periodic array of sensors for cameras

  6. Reversed fan and external filter: results on Ask Slashdot: Dealing With Electrostatic Contamination? · · Score: 2

    Here is what I have done with excellent results:

    My NAS had a small fan, blowing warm air outside it. I remount the fan so that it blows fresh air inside the NAS and I added a custom external filter on the intake. The filter doesn't limit the flow (big accordion shape and stockings-like fabric). I plugged some holes to optimize the flow.

    The NAS is sitting on the floor under the stairs, a rather dusty environnement...

    After two years I inspected the NAS, here are the results:

    - No dust soots the NAS, on some parts there is only a very thin grey layer of the finest particles that goes through the filter. It is much thinner than a coat of paint, nothing to worry about for the years to come.
    - Filter is easy to clean, no need to open anything.

    Also the NAS is actualy cooler, the hard drives report 35C instead of 37C, this is a side effect of the reverse flow which is more turbulent and effective for going everywhere to cool the parts.

  7. binaries just works ? on Gnome Founder Miguel de Icaza Moves To Mac · · Score: 1

    he speaks of "the binaries just works", but he neglects to mention that you still have to look for them in really random places over Google

    He will have a first hand experience to this when he will look for a simple text editor with syntax highlight :
    I tried to find one, have installed two or three, but there're far from what we have in any Linux distro out of the box (usability and stability).
    Oh! Wait, he will maybe pay for one of the store ? Good for him, but I won't pay just for being able to edit code...

    Also: Did he noticed that pipe, backquote, square brakets, ... are not displayed on the keyboard? I suggest he googles the key combinations to get them, because they aren't mentionned in the system documentation... Or, if he has time, he can use the visual keyboard to find those combinations, pressing modifier keys until the required character appears somewhere... What a shame.

    In a few years he will find out that he needs to pay to upgrade his OS because the new apps won't start on his otherwise functionnal system. New binaries just won't work.

    Working on the Mac OS system is quite painfull for a developer, and frustrating.
    The end key is driving one crazy: instead of going at the end of the line it goes at the end of the paragraph. Seriously who needs this?
    Oh! And if the window management is so painfull to you, you can *pay* a small app that eases the process of arranging windows (this is not a joke, an Apple fanboy told me that). However you still have only a small corner to resize them, on their right only... What a shame.

    I wish good luck to him, we will see in a few months how his coding productivity looks like.

    I guess someone has already invented a captcha box to get rid of robocalls.

    Is there a problem using this kind of device?
    I can't remember but it seems to me that it has already been discussed here on slashdot, hasn't it?

    We don't have that kind of problems in my country, so I haven't looked for a solution like such.

  11. Rotation and non-square pixels on Ask Slashdot: What Is Your Favorite Monitor For Programming? · · Score: 1

    You forget that the OS will rotate the display.
    If it doesn't, then you're right: square remain square and circle is still a circle, but you will need to tilt your head in order read the screen...

    If the OS rotates the display on a non-square pixel device, then its ratio has to be taken into account.
    Actually it should use the inverse ratio, shouldn't it?

    What they have done at my company makes sense:

    Use firstname.lastname999@domain.tld where 999 is a 3 digits random number (retry in case of colision, also improper funny numbers are left over).
    This apply even for non-coliding names, the first one to be registered will have the digits also.

    Reading the posts above, I find that it is the best way to go.

  17. Other interesting Boeing paper on Excessive Modularity Hindered Development of the 787 · · Score: 1

    In this artcle they cite a 2001 Boeing paper which I find very interesting.

    All those MBA bosses should have a look, it seems very few have learned any lesson since then.

    The point is made that not only is the work out-sourced; all the profits associated with the work are out-sourced, too.
    ...
    A strong warning is included about the perils of sub-optimum solutions in which individual cost are minimized in isolation.

    It is quite enlightening, given that their problem today could very likely come from those interdepartmental interactions not thoroughly planned enough.

  23. Re:Gravitational sonar on Dr. Faragher Answers Your Questions About the Future of Navigation Technology · · Score: 1

    Thank you for reading and answering!

    The Darpa page you link says:

    The Precision Inertial Navigation Systems (PINS) program seeks to use ultra-cold atom interferometers as an alternative to GPS updates. Advancements in atomic physics in the past 2 decades have given scientists much better control over the external quantum states of atoms, including deliberate production of matter waves from ultra-cold atoms. This has allowed development of matter wave interferometry techniques to measure forces acting on matter, including high-precision atomic accelerometers and gyroscopes. An inertial navigation system that used this technology would have unprecedented drift rates, and many scientific and technical challenges remain. The PINS program will demonstrate a high-precision atom interferometer inertial navigation system on an aircraft by 2013, with a total system volume under 20 liters. Since this is an entirely inertial system, it will require no transmissions to or from the platform, thus enabling a jam-proof, nonemanating inertial navigation system with near-GPS accuracies for future military submarines, aircraft, and missiles.

    Under 20 liters, this fit in a 27cm high cube (11 inches).

    We're not yet at a pocket sized GPS altenative... but this size is already small enough for many kind of vehicles.

    Please,could you elaborate a bit about the gravitational sonar and what do you mean by "nearly-unbelievable" ?

    My question hasn't been sent to you:

    Does the gravitational field strength could be used also for NAVSOP ?

    Maybe slight natural variations, and buildings, underground structures like metro, subways, large sewers can be sensed by gravitational sensors, at least the new ones with atom waves interference...

    but I see that cold atom interferometer is mentionned in you last answer as a big improvement in this field.

    Also in your last answer you didn't tell if this kind of correction could be used for NAVSOP or if the interferometer won't 't fit in a reasonable small piece of hardware.
