  1. Happens all the time on Ask Slashdot: Have You Experienced Fear Driven Development? · · Score: 1

    Worked at a major software house serving ðe biggest telecom operators all over the world. Ðe company started doing top notch Unix software, even creating its own SQL-like DBMS when Oracle was not good enough. Everyone from ðat era got promoted out of technical oversight over what was produced later, and ðe people who produced software later also got promoted out of technical oversight, so we were left with Microsofties who feared ðe Posix code, did not understand it, and were capable only of implementing overdue business requirements, not of any technical improvement or even technology updates.

  5. I call BS. For most non-enterprise purposes, MySQL is more than good enough as long as you make regular backups and use any modern operating system with a journaling file system.

    It may have changed, but its hot backup tool was proprietary. Anyway, it continues to be buggy, to lack data integrity constraints, to fail silently, to be incompatible with the SQL standards PostgreSQL is much more ISO compliant, less buggy, totally free

  6. Friends do not let friends suffer MySQL. Go for Glom or LibreOffice Base over PostgreSQL.

  9. Re:A few problems... on Can Reactive Programming Handle Complexity? · · Score: 2

    Is SQL really that right language for encoding business logic?

    Yes, SQL is quite adequate, more so than most due to being declarative. The issue is not SQL per se, but poor support for it in everything but PostgreSQL and IBM DB2. The advantages of procedural languages (including OO and functional ones) are more in standardisation than in the language per se.

  10. Re: Complexity is not a feature, it is a bug on More Bad News For the F-35 · · Score: 1

    Sure enough. I do not think the Gripen will be it. I think it could be, just as ðe Harrier was; but in ðe end ðe probability is more of a massively expensive, not quite up to ðe task fleet of F-35s, and as a B plan ðe evolution of current aircraft while new, simpler ones are designed.

  11. Re: Complexity is not a feature, it is a bug on More Bad News For the F-35 · · Score: 2

    Wrong on all counts.

    First, if you reread my post, I said it was just an option, besides revamping current models and creating a more focused aircraft.

    Second, ðe US already did something like ðat with ðe Harrier II.

    Third, ðe Sea Gripen is already in development and will probably be built as a result of Brazil’s need of new aircraft for its current and future carriers. 24 or such units is not a bad first order for a modification of an existing, & already cheap, model.

  12. Complexity is not a feature, it is a bug on More Bad News For the F-35 · · Score: 4, Interesting

    So many failures by trying to be all things to all people as long as the taxpayer foots it all.

    My native Brazil has decided on ðe Saab JAS 39E Gripen NG, as did Switzerland where I lived. Two very different countries, very different needs, and sure enough the Gripen even in its NG version cannot do all the F-35 should be able to do — but it does not need to. It is more of a versatile aircraft, doing passably well in its intended deployments at a reasonable cost, than a do-it-all.

    It is not to say the US should just ditch ðe F-35 and localise ðe Gripen just as ðey did with ðe Harrier. But it could be an strategy: to have a flexible (‘swing role’ is what Saab calls it) main aircraft, perhaps the evolution of ðe F-18, perhaps a pared down F-35 just as ðe Chinese did, and dedicated planes to do things ðe main platform cannot do, such as ðe A and B planes: ðe A-10, ðe Harrier &, yes, ðe B-52, or evolutions or replacements ðereof. Theoretically a single plane should be cheaper to keep ðan several ones, but not when its costs spiral out of control.

  16. Improvements have to come a few at a time on Why Don't Open Source Databases Use GPUs? · · Score: 1

    All of these SGBDs are actually toys being sold for more then they are capable of. So developers there have to try to catch up to PostgreSQL before it becomes (even) easier to use and eat their lunch.

    Meanwhile, the issues meriting scarce development and, mainly, review time at PostgreSQL are more interesting than accelerating a few workloads in hardware which is not yet in the servers out there. Things like making PostgreSQL even easier to install, set-up and manage, even more ISO SQL compliant, even more capable, even better than NoSQL at NoSQL loads

    Now, if you can show your GPU aware PostgreSQL extension or modification, and show it is generally useful enough to merit review time for the next release why not?

  17. Not a snap decision on US Spying Costs Boeing Military Jet Deal With Brazil · · Score: 2

    The FAB (Brazilian air force) always wanted the Gripen. It was not a snap decision; it was the government finally realising it is better to be a junior partner than a minor customer.

  18. We do not have the commitment on US Spying Costs Boeing Military Jet Deal With Brazil · · Score: 1

    In the 1980s the Brazilian government wanted to do just that, after the AMX project, where we were junior partners to the Italians. But the 1980s debt crush, followed by the 1990s bubble burst and tiger economies’ crises, and then populist governments during the 1980s and 2000s, totally killed any viability to a Brazilian supersonic.

    Not only that, the market is already too cramped. It makes much more sense to just become a junior partner with Saab (now; it could have been someone else, even if it is hard to see whomever) in the hopes of becoming an equal partner in the future.

    Not that I believe in any such future. We simply do not have neither the long term vision, nor the first rate education, nor the need nor the demographical viability.

  19. Not so simple on US Spying Costs Boeing Military Jet Deal With Brazil · · Score: 1

    The best for what against what?

    Both Brazil and Switzerland lack credible menaces. For us (I am Brazilian but have an attachment to Switzerland, my son having been born there), the Gripen is more than enough, and enables us to participate in the project, which is more useful than simply buying the latest toy.

    BTW, why is a Swiss report written in English? I would expect German.

    The US has **the most journalistic freedom in the world**

    wrong, according the journos themselves at least; US doesn't even make it into the top 30.

    Journos are hardly the best judges, as they have their collective bias as well. And it seems to be Leftist: notice how Venezuela, Argentina, Brazil and Israel are all lumped together, while Venezuela has effective persecution of the press; Argentina is trying to follow on its heels, fortunately less effectively; and Brazil is solidary with these governments. In fact, the three governments have the same tendencies; I would argue the difference in the effectiveness of political censorship is less a difference of substance in the government and more of different strengths of the civil societies.

    Israel should be about par with Europe and North America, which shows journos ignored the circumstance of its living in a continuous state of war.

    So, a mirrorless system camera is even easier to hack, besides being more adequate for video (not blacking out the visor while shooting). Four Thirds all the way for me

  25. Awesome, but the wrong hardware. on Canon DSLR Hack Allows It To Shoot RAW Video · · Score: 1

    Awesome, but an SLR is simply inadequate for video. What you really want is a mirrorless system, preferrably one optimised for digital sensors. The only one nowadays is Micro Four Thirds, with Olympus, Panasonic &, soon, Kodak cameras. Of these, Panasonic is the more video oriented, and its flagship hybrid GH line cameras have already been hacked, so I would be interested if someone replicated this hack there (or at the nearly equivalent Olympus OMD EM line).
