  1. Re:Or anything running in a VM on Asm.js Gets Faster · · Score: 1

    In the server world these days we don't run things on physical hardware usually, we run it in a VM. The less resources a given VM uses, the more VMs we can pack on a system. So if you have some crap code that gobbles up tons of memory that is memory that can't go to other things.

    First - I write this as the sort of programmer who agrees with you in principle. I make my code as light and tight as possible.

    But as a programmer, I get pissed when SysOps bitches me out for making tradeoffs that drastically improve performance - Such as trading off RAM for CPU usage. RAM comes cheap. Storage comes cheap. Hell, even CPU time comes cheap, but when you take a 24-core 256+GB behemoth, and oversubscribe to the point that nothing runs well on them? Don't blame the programmers, bro, look in the frickin' mirror.

    VMs can indeed save admins a ton of work. They make HA possible, they make backups trivial, they minimize physical machine babysitting, they make spinning up a test bed truly a joy. No doubt, best tech ever when dealing with a large number of light workloads you'd like isolated from each other.

    Programmers have a job to do, just like you do. And when that involves serving up a lot of data to a lot of users, yes Virginia, that takes resources. Go ahead and run my SQL instance as a VM for all the benefits mentioned above - But until you give me a beefy box at 1:1 provisioning, don't you dare look my way when I bring the box to its knees by actually using those resources.

    Your real point seems to fault CS for primarily using English, the second-most spoken language on the planet. Okay, fair point - Convince everyone to switch to Mandarin, and I'll play along for the sake of efficiency.

    Because like it or not, this does boil down to efficiency; If everyone on the planet would just pick a single language and stick with it, we'd all have it a whole lot easier. Hell, let's even pick a designed language like Esperanto, so no one has "home court advantage" - $Deity knows I'd give my left nut to actually have everyone use a language without a million and seven historical irregularities.

    But no, instead of learning from our mistakes in the real world, instead let's try to turn the most successful monoculture ever to arise in the history of humanity, into just one more polyglot disaster; where the ability to share earth-shatteringly good ideas becomes more a matter of imaginary lines on a map than of technical prowess.

    I've seen that one before. Pretty good, and really makes a person stop and think. Except... It kinda misses the point. Yes, my culture gives me something of an advantage in life - Because we won. And yes, we had our bad-old-days, when "winning" meant someone else lost. But we've moved past that, and have invited everyone to the party.

    The problem there comes from everyone else still trying to "win" by dragging western culture down to their level. Yes, you can have capitalism. Yes, you can have democracy. Yes, you can have the role of religion marginalized in your political system (though sadly, we all still have quite some way to go in that regard). Yes, you can have English. That combination won, long long ago. Stop fighting it, rather than joining the winning team.


    (which only exist because of pervasive systemic racism and segregation, by the way), your knee-jerk reaction is that it's just bullshit?

    Okay, so moving beyond "language", what prevents any English-speaking American black/hispanic/female learning to program the same damned way any white male programmer did? And no, I don't mean "college" (I have yet to meet a single good programmer who didn't already have the fundamentals down well before college). I mean pick up a book on programming, read it, read it again, fall in love with the subject, and spend the rest of their lives honing their skills?

    And for reference, before you say that I have an advantage because of the "culture" targeted by that book - For me, "that book" meant the GW Basic language reference manual (old-style three-ring binding and all). About as "culturally accessible" as your car's service manual. Nothing but the facts - This function takes these parameters and does whatever with them. And before you say "you had a computer and that book", I actually encountered that book and my first PC in my third grade classroom, spending as long after school every day as they would let me stay, to learn how to use it.

You need the ability to break big problems down into small ones, and small ones down into individual comparisons and actions that don't even look like "problems" anymore. You need the ability to see past what people say they want, and give them what they actually need. You need the ability to think of every possible way the process could go wrong, and handle that even if it will realistically never happen. And finally, relating back to "culture", you need to lose the filters most people view the world with and cut right to the root of the situation - You need to work around culture, around "perspectives", not "embrace" them.


    In fairness, yes, you can call the modern world of IT largely a "boys' club", and yes, we tend to behave in ways that most of the modern corporate world would consider slightly over the line. But not because we don't welcome women - Simply because we don't have any around that we need to hold our tongues around.

  7. Re:OMFG on Why Charles Stross Wants Bitcoin To Die In a Fire · · Score: 1

    Since Bitcoin is deflationary, it makes more sense to stockpile (or hoard) it than to spend it. That is also what makes it more like a commodity than a currency.

    The biggest problem with the whole "deflationary" argument - And indeed, with any inflationary economy? We have a finite amount of resources on-planet. And while I certainly have high hopes of our species eventually making it off-planet (for real, not this "Billions to get a few guys to the moon for a few days" crap) - it sure as hell won't happen in my lifetime, and I see no reason to pretend otherwise.

    So whenever we talk about why such-and-such a system (gold, Bitcoin, even fiat currencies such as the USD currently wavering on the edge of "negative inflation") "can't" succeed because deflation encourages hoarding, keep in mind what you really talk about - Money exists to make it easier to buy "stuff". If more money exists than stuff to buy with it, the stuff becomes more expensive. Inflation of a currency essentially just measures the inverse of the corresponding deflation of reality.

    Guess what? Reality always wins. As soon as you have 100 people desperately in need of 99 cheeseburgers, inflation approaches infinity, but you still only have 99 cheeseburgers.

    When you talk about people hoarding Bitcoins, you conveniently gloss over the fact that people could just as well hoard gold and ammunition and canned goods and quality hand tools and clothing - And make no mistake, some people do, but most of us would rather just go about our daily business of living. Will some people hoard BTC? Yep. So what? Most won't.

    Finally, you also need to consider the rate of deflation, vs the yield on reasonably safe investments. If you can make 8% investing vs deflation of 3%, only an idiot would choose to hold the currency instead of the investment.

    Until everyone does it and the pricing structure changes.

    People tend to have a lot of misconceptions about the energy industry. End-suppliers, like your utility company, don't care about the absolute price at which they sell* - They hedge their entire supply, and charge a more-or-less fixed margin on top of that. They don't make more or less when the actual supply price goes up or down.

    Now, on the supply side, you have multiple layers of demand loading. You have the dirt-cheap baseline load, then you have some spare capacity in the baseline systems (usually not that much, on the order of 20-25%), then you have easy-to-online spare capacity (often from some form of short-term storage), and finally you have peak load generation (normally-offline gas turbines, in general). Of course in reality you have far more tiers than that, but you get the idea.

    All of those cost money to maintain, whether they feed the baseline or the peak. The peak costs more because you essentially have generation capacity sitting idle all but 5% of the time, yet it needs to pay 100% of the bills to own and maintain it. So even there you don't have the suppliers making out like bandits.

    Disclaimer - I can only speak for the US market. They may have something radically different in Japan, but overall, I would bet my eyeteeth they still use some form of hedging to maintain relatively fixed margins.


    * While technically true, price does tend to affect how much effort end-users put into conservation.
