  2. Re:Amazing how times change. on Who Makes the Best Hard Disk Drives? · · Score: 1

    Backblaze is actually quite happy with the Seagate drives: The performance is consistent, and prize is low. The 4TB drives are good, and they want to buy Seagate 15TB drives. They only had trouble with the 1 and 2TB series.

    Hypothetical example: If 50% of the drives fail, but the drives are half as expensive as drives with a 10% fail rate, its better to choose the former. For the same money, you will have 10% more disk space left. It may be some effort to swap, but they rely on a RAID anyways.

  5. Re:Is this a cuteness thing? on 200 Dolphins Await Slaughter In Japan's Taiji Cove · · Score: 1

    A range of tortoises and sharks have already gone extinct because we eat them. Overfishing is wide-spread. I would object much less to dolphin and whale killing for meat if they were bred for that purpose. But they are not. Fishers are just emptying the ocean. That's the difference.

    And later on cry foul on why we have to create regulations, and they can't fish as much as they used to (e.g. the new overfishing regulations by the EU).

  6. Re:Bios code? on Ask Slashdot: What's the Most Often-Run Piece of Code -- Ever? · · Score: 4, Insightful

    Lets approach this analytically.

    What platform has the most computation power (number of CPUs x speed)?
    Due to the increase in speed, we can disregard any CPUs built before 2000.

    In number, mobile phones are the largest platform. So I would reckon, some GSM codec/cipher.

    I think, for now, microcontrollers can be ignored, because they have much lower computational power.

    Desktops and supercomputers have more power, but are they excessing the mobile phones? If they are a relevant portion, then across mobile phones and desktops, perhaps some code related to network access is the most-run.

    I doubt it would be something kernel-related (like bootup, context-switching), because the kernel usually does not (or should not) take up a lot of the computing time. If we go by number of entries only, then perhaps some networking code.

    If so, I'm not sure which layer to look into though. The lower ones are called more often, but media is not the same across use cases.

  9. Re:scary on 23-Year-Old X11 Server Security Vulnerability Discovered · · Score: 5, Insightful

    Given that you need to be using obsolete 90s bitmap fonts for this to be an issue, and that X11/X.org is never run as root, I'm not sure that "scary" is the word for this (there's a reason it hasn't come up before in the 23 years since it was introduced).

    Correct in principle, except for two remarks:

    • X runs as root, and has always. Just like getty.
    • If you craft a new bitmap font, running "xset fp+" as a user has the potential to gain you root privileges.

    So yes, not "scary". Just a critical security bug.

  11. Re:There's one born every minute. on How To Create Your Own Cryptocurrency · · Score: 2

    Lets ignore the point of the website -- creating similar source codes from a template -- for a moment.

    The *business model of this website* is interesting. Could it be the future of revenue for developers? You set up your Software as a Service, and ask for payment in a quick and painless form (BitCoin, or what Mozilla tries to do with WebPayment). With the rise of electronic currencies that can handle small transactions without friction, is everything going to be online, and commercial?

    All these "convert your image to another format" websites that are frontends for ImageMagick, the "video effect" websites, the themes for Facebook websites, promoting posts on Facebook, additional filter effects for Instagram, sounds, game levels, etc.
    All these are useless to a poweruser, but neat fun for the average computer user, who could be milked 1 cent per person. There is large money to be made from their large number?

    If so, the AGPL is more important than ever.

  12. Re:Obvious, but worth restating. on Not All Bugs Are Random · · Score: 2

    Yes, we can retitle from "Not All Bugs Are Random" to "White-Box Testing Is A Real Thing"

    It would make more sense, because there was never an assertion that bugs were random.
    Furthermore limit testing is not a new concept.

    I haven't read TFA, but the newer programming paradigms, such as agile/XP, are heavily test-based. Instead of writing a design, implementing it, and then testing it in production, we start with writing test cases (unit & integration tests, and hopefully some behaviour tests). When they are all fulfilled, we can stop programming.

    But how do you know which tests -- beyond functional ones -- to write? Writing and evaluating is already non-trivial for realistic quality tests (throughput, security). Surprisingly, random input tests work quite well (generated either completely random or from regular expressions).

    Maybe TFA is suggesting to consider the building blocks a test element is made from, and take into account their limitations to craft test cases (white-box testing when doing test-based programming). I'm not saying it's new, but it makes some sense to me to re-iterate from that point of view.

    From experience, when doing my thesis: ...

    Well, symbolic computation did not work either on Octave...

    Did you try sympy? I was amazed recently how well it works -- you can start with certain assumptions and derive formulas/equations from them, output latex, and finally evaluate the equations, for instance for matplotlib plotting. Then you can change your assumptions and rederive new equations / plots.

    Of course it depends what kind of math you do.

    I just want to point out one counterexample: Blender. The work done in the 2.5 version was huge, but it allowed lots of improvements later. Totally worth it.

    Mozillas refactoring of Netscape enabled Phoenix/Firebird/Firefox 1.0. If you have dedicated developers, a refactoring will also make them understand the codebase fully, making it easier for them to change larger parts such as design aspects.

    Xorg is trying to do the same thing with the X11 codebase. The first step was modularizing. That's a project you can get into if you are looking for something difficult but worthwhile.

  19. Re:Love KDE on KDE Releases Applications and Development Platform 4.12 · · Score: 1

    It has really come along from the 4.0 days. Very stable for me - use it all day, every day at work. Only problem I have is that if you have a auto-hidden panel and a full-screen Citrix app then there is a 10px portion of the screen that is unusable right over the auto-hide hover area.

      Other than that - it's awesome. I can't live without Kontact, Dolphin, Okular and Gwenview.

    Can't say the same. I use it (4.10), but there are sometimes Plasma crashes under high load; the battery icon gives out a false empty battery warning on resume from RAM. Overall, the UI is clunky. KDE has never had good UI design & nice themes. There are the moments where you feel like operating Windows95.

    GNOME3 should be stable enough now, I'll probably switch back to it soon. It gets out of the way and is appealing. I think the lessons from Mylyn should be taken seriously.
