    Even with search, they were late, with a pretty bad search engine that just managed to be the biggest one after a while.

    Indeed. Works very well as soon as you understand how to write Python classes in C.

    The other thing I am currently investigating is embedding Lua in C for limited scripting capabilities. This seems to be extremely easy. It comes with some limitations, for example limited pattern-matching, i.e. no PCRE (can be retrofitted with some effort though).

    Learned it, was appalled by the shockingly bad and complex design (I learned C and Eiffel before, among others) and decided to use this mess only when there was no other choice. To be fair, the "crap for the masses" (Java) is not really any better.

    These days I use Python with embedded C modules for larger things or plain C or Perl or Python for smaller things.

    Indeed. When your will does not change reality (and with anything Physics it very much does not), then a "triumph of will" becomes terminal stupidity.

    These are people that have no clue what a "fact" is and that it does not go away by ignoring it. Hopefully, when humanity starts over, it will be with a way to identify these people early on to make sure they do not get any power whatsoever to decide where things are going.

    Same here. In a sense, we are the new 1% though...

  7. "More ad revenue" is not "growth". It is just shifting around of money. Also, if they do not have the ad revenue now because of their visitors, if they ban/intimidate/moderate their current visitors away, they will have less visitors and will become irrelevant when people move away to places where they can actually express themselves. In the end, this may just kill Reddit, in a typical result from greed combined with stupidity.

    The smart and capable ones already do. The others are incapable of learning and can only be hounded out of the profession they serve so badly. The sooner, the better.

  9. It is called "good engineering" on Ask Slashdot: Why Do Popular Websites Add New Features So Sparingly? · · Score: 5, Informative

    Following every hype, adopting features fast and without clear goal, etc. is called "bad engineering", incidentally. The problem is that there are a lot of bad and really bad people at work on the web and on apps that I will refrain from calling "engineers" because they do not deserve that title. Hence doing it right for a change stands out. In other engineering disciplines it would not or at least not nearly as much.

    I have met somebody that survived it. But I knew him for some months before he told the story and it was not readily obvious before. And the ones that do not make it, you do not meet.

    Or to put it otherwise: You are both stupid and clueless. An ideal sheep to be manipulated into doing things that are bad for you but make others a ton of money.

    Observable facts say linear or worse, and there have been quite a few breakthroughs to allow even that.

    My guess is that the idea of the QC will end up on the trash-heap of science, like converting lead to gold. Possible today, but completely useless.

    I know. But due to the general cluelesness observable here on this topic, I uses 1QBit/1bit as an obvious lower bound.

    "Immediate" is O(0). O(1) is "you have to wait, but how long does not really depend on the input". Does nobody understand the fundamental definitions anymore?

    Indeed. Looks very much like it is actually sub-linear and will hit a wall pretty soon. The effort invested today is massively larger than back in 2001 and they still have only a pathetic linear increase to show for it.

  16. Re:A few more bits... on Scientists Break Quantum Entanglement Record At 18 Qubits (zmescience.com) · · Score: 2

    That is the big problem with QCs: Computations on them are not divisible in smaller sub-tasks. If you have an arbitrary large number of 299 QBit QCs, they are completely worthless to solve even a single 300 QBit problem.

  17. Re:A few more bits... on Scientists Break Quantum Entanglement Record At 18 Qubits (zmescience.com) · · Score: 3, Informative

    Actually quite a few more. Even to break an ECC modulus, they need about 300 more. With the scaling of around 1Qbit/year since 2001 (when they factored 15 on a 7 Qbit machine), my guess would be that it will take a few centuries to get there.

    Silicon scaled exponentially almost from the beginning and continued to do so for a long time. That is what makes it powerful today. QCs have never scaled better than linearly and are still at a ridiculously useless size as a consequence, after about 30 years of applied research. They may also well scale sub-linearly. The whole thing would have been dropped as a dead-end a while ago, except that many humans run after every hype that tickles their fantasy.

    QC is limited only by the size of a stable system that you can build. But the stable systems you can build give you any/all/every answers IMMEDIATELY.

    Looks like you are the clueless one here. No, it does not give you answers immediately at all. You still have to feed in the data and do computation steps and you have to do this slowly and carefully to avoid decoherence. And if it decoheres, you have to do everything again from scratch. And due to noise, you either have to add a lot of error-correcting steps or run it for a lot of times. There is nothing "immediate" here.

    Probably. With the progress they are making, they will most assuredly not deliver in the next 50 years and without any fundamental breakthrough (not on the horizon and cannot be planned or forced) it may take 1000 years or longer for this to become useful at all. At the moment, they seem to be able to add about 1 Qbit/year for actual computations. And the impression that this may scale sub-linear is not off the table at all.

    Time for the hype to die down, there is nothing useful this technology can do.

    Before that, these things are useless to break public-key crypto, at least the one that has not insanely jumped on the ECC-hype.
    Since they has 7 qbits in 2001, and now they have 18 qbits about 17 years later, looks to me this scales with +1 Qbit/year at best. May still scale sub-linear. Anyways, I guess nobody living will see these things become useful.
