  1. A more serious problem with forced automatic updates is that it causes everyone to update even if the newer version has a bug that causes Firefox to crash. Might not be as common now, but I still remember at least one instance from the Firefox 2.x era where it was better to simply hold onto the existing version rather than have the browser crash on all your favorite sites.

    (Press CTRL + Shift +E) Everybody would knew that

    There's actually an icon at the top right corner...

    Of course, I knew that Tab Groups existed for quite a long time, but didn't use them as the implementation is awful - on par with something that an average programmer could do themselves. The most obvious bit is that creating a second tab group instantly makes it harder to manage tabs outside the current tab group.

    It's also pure overlap with an existing tag group system, known as a window.

  3. Re:Not programming semantics, but the coder on Linus Rants About C Programming Semantics (iu.edu) · · Score: 2

    Modern compilers won't notice the pointer changing between those two conditionals, with it being loaded into a register that won't be modified in another thread. Some compilers may realize that it's impossible to enter the third block, and simply purge the code. In either case, the third block is pure fluff that should be removed.

    If you're in the rare situation where said pointer can change suddenly, then you should:

    • Declare the pointer as volatile.
    • Copy the pointer to a non-volatile variable
    • Use synchronization to ensure that you have exclusive access to the pointer
    • and/or, not play around with data types without knowing how they work.

    Also, the person writing the code mentioned that the compiler had a bug - but if such a trivial bug did exist, it would either be fixed by now, or the company making the compiler would be laughed out of existence. besides, paranoid individuals can use a debugger to disassemble a compiled executable and verify that the write code is generated.

  4. Re:Just wait.... on $70k Salaries Didn't 'Backfire'; Gravity Payments' Profits Have Doubled (inc.com) · · Score: 1

    Paying $70K created such efficiency and opportunity that it doubled profits. So why not go above $70K and make even more money? Would $140K minimum quadruple profits? Probably not, there's a diminishing return here I suspect.

    This theory works only for menial and robotic tasks, where a linear increase in wages can correlate with a linear increase in productivity.

    If the task requires creativity or cognitive skill, rewards only work as long as you give enough money to make sure they aren't worried about money. If it's above a certain threshold, it attracts undesirable talent, and causes productivity to drop.

  5. Re:Question on Firefox Support For NPAPI Plugins Ends Next Year (mozilla.org) · · Score: 5, Informative

    What is NPAPI ?

    NPAPI is the legacy plugin system used by browsers that allows webpages to serve executable content without the user having to download a file.

    This system is used by Flash, Unity, Java, and various unimportant plugins. Of these, Flash has an arrangement with Adobe, Unity has an exit strategy, and Java is completely neutered as it was for quite some time. The unimportant plugins are unimportant (and if they were, they'd have fixed it by now.)

    and does this have anything to do with the add=ons and plug=ins specific to Firefox and Seamonkey
    SAome of which break every time they put out a new version of FF

    Those are extensions, which is completely different.

    Apparently, concatenation isn't as effective as it could be. It will be at least as strong as either MD5 or SHA1, and while it seems that you'd get a 288 bit hash, it's about as strong as if you had 174 bits.

    If you have a bomb and want to detonate it, you make sure nobody else sees it. You don't show it to a science teacher, nor do you have an audible alarm. A kid who's capable of building bombs would already know this.

    I recall "Please update Flash/Java/etc." was using Javascript to redirect you to a random third party site, and immediately attempted a software download.

    In any case, the article is referring to guidelines on the ads amazon should accept, which include fallbacks in case Javascript will not function for whatever reason. If there's flash content, it's likely that it may be pre-disabled and either results in a big "click-to-play" block (ugly web design), or will never get played should the ad developer create a fallback for that.

    A new web-based exploit is known as "a Tuesday", in the same way that a boot sector virus is "a monday", and a .EXE virus is "a wednesday".

    A common thread of malware is that it uses whatever means to automatically execute without user interaction. Simply prevent stuff from automatically executing (NoScript, Flash block, or click-to-play), and the infection rate will become negligible - and perhaps more traceable in real-time.

  12. Re:Something wrong there on Google Self-Driving Car Rear-Ended In First Injury Accident · · Score: 1

    It's possible that the Google car is not giving out "body language" that telegraphs behavior before it happens.

    Does body language include the red lights at the back of the car indicating a break light, along with that the cars on the left were rather slow (indicating at least some form of red light), and that the driver behind the Google car was closing distance with the car in front for a period of 2 seconds?

    Linked video: https://www.youtube.com/watch?...

    I'm certain the driver would likewise hit a parked car, which has zero body language.

    If the Google car just enters a slowing-down event, it might be undetectable.

    If the break lights at the back of the car don't work, then the car is not fit for road travel.

  13. Re:NES vs. DOS on Retro City Rampage Getting a DOS Version · · Score: 1

    Seems funny when I think about games on DOS vs. NES. Most of the time, NES games seemed much better.

    Around that time, the PC was rather simplistic and not designed for gaming. Graphics were usually EGA (or worse, CGA), and didn't have any sprite support that other systems in that area liked to use. Sound was a cheap internal speaker that was more annoying, especially with lack of volume control.

    It took until the 386/486 era before PCs started becoming strong, but developers around that time still needed to think about less powerful systems as opposed to knowing that each system could at least handle a minimum quality of graphics.

    Once PCs became modern - VESA, Soundcards, and breaking 1MB barrier, consoles were mostly in catchup. It took until 2000 before game consoles had an internal hard drive.

    At the time, NES didn't seem very limited. IT had plenty of great games that played quite well.

    Also around that time, programmers were much more skilled at optimization tricks - and didn't have to worry about the operating system.

  14. Re:Google should revert that decission on Ask Slashdot: Options After Google Chrome Discontinues NPAPI Support? · · Score: 2

    But the assholes at the Mozilla Foundation won't implement it because they prefer shitty insecure APIs like NPAPI.

    If you're worried about security, then it's a better idea to worry about automatically executing anything that comes down the pipe (for example, a rogue Javascript ad that redirects you to a "please update java" page) as opposed to the mechanism at which it automatically executes (as one sandbox break gives easy access to the whole system.)

    That's a lesson learned from the pre-1995 virus era. If you don't automatically execute whatever is in your floppy drive (the default setting for BIOS), you don't get infected.

    Are you writing the search/compression/render capability from scratch, or are you using a library to handle that job for you?

    If you're handling more than one document type, then go for a library. I don't have a recommendation myself, but I'm sure you can find them on a search.

    Also, don't worry about compression, as modern .odf/.docx is already compressed with something compatible with PKZIP.

    For 99% of the applications out there, there's no reason not to do it in the browser if you're starting from scratch today.

    One major reason - if the browser fails, it takes out everything running under it. Failure can be as simple as a crash, to a javascript exploit that interferes with the browser, or the browser needing a few minutes just to crunch memory bloat.

    Although browsers have since gotten better, I still don't trust the browser to resume where I last left off - the best I can do is force firefox to crash, and when it resumes, it gives a list of windows that I could potentially restore.

    Ending compulsory schooling? Good luck with that! Surely nothing could go wrong with that!

    Demands to end compulsory schooling is actually one of many random demands due to people not being sure how to fix the problem. If you feel the approach is incorrect, then you should suggest a better demand (such as exempting a small portion from compulsory education).

    For the same reason we don't let children take any important decision for themselves before they're 18... They lack critical thinking skills, foresight and maturity to make them.

    They are still more than capable of telling if something is completely dysfunctional. Yet, they're completely unable to fix it because "they lack critical thinking skills, foresight and maturity to make important decisions" and therefore shouldn't be allowed to do so.

    Got a student taking basic math despite having already mastered it? Nope, got to finish basic math first.

    claims that the under 40s expect everything to 'just work' and have no idea what to do when things go wrong

    I have a Samsung computer monitor that isn't properly detected if I use the DVI cable, although the VGA cable works fine. This prevents Mac OS from detecting the monitor, and confuses Windows. (The technical details: it's not transmitting EDID over the DVI connection.)

    The quick fix for Windows worked for a while, but a driver update changed how things work and would be constantly confused by that monitor. The proper fix requires opening the monitor, using a multimeter to find what's wrong with the DVI connector, and fixing or replacing it. This is not something you can do on a weekend, as opposed to fixing a larger appliance.

    The problem isn't around knowledge, but that it requires equipment not expected to be in a normal home. A house can have tools available to fix large mechanical objects, but not extremely delicate electronics that require an electron scanning microscope to properly fix. The repair costs for devices usually indicate that the whole device has gone bad as opposed to an easily swapped component, meaning the manufacturers also have trouble getting things to work as well.
