Comment Re:"Anonymous platform moving away from anonymity" (Score 3, Interesting) 41

I suspect that their plan to move away from their core business is totally doomed; but I would also suspect that they came up with that plan because their core business was totally doomed(and they couldn't find some idiot to aquire them for silly amounts of money, maybe Yahoo was busy when the called...).

The world is pretty full of message boards and chat apps; and the combination of proximity filtering and 'anonymity' produces a really, really, low-value environment. Because of the geographic boundaries, it's useless for any of the 'connecting with other enthusiasts of my weird and potentially embarassing hobby/fetish/etc' applications of anonymity, since you can only interact with people in a fairly small area around you; but since it purports to be anonymous(obviously, an application running on your phone with location data mandatory isn't anonymous at all from the perspective of the company operating the service) it mostly attracted the...high quality comments... that people wanted to make about each other; but weren't willing to say to your face.

Shockingly, people's appetite for that appears to be limited; and the most enthusiastic users are the people most likely to drive the rest of the users away and generate enough unpleasant stories to spook potential advertisers.

It must be pretty cool to be in a position where you can commit fraud against ~2.8million people, sit on the proceeds for several years; and then settle the whole matter for 'compensation' that, at worst, might wipe out your original profits on the fraud.

Not quite as good as impunity; but perhaps an even better mockery of the perception of 'justice', since the whole process gets to play out as a pitiful farce, rather than just being ignored.

Incidentally, why is it that, given the American propensity for a good spree killing, you never hear about unpleasant things happening to the people behind schemes like this? Occasionally somebody shoots up their workplace and kills an immediate supervisor or the like; but nobody ever seems to go any higher up the food chain.

So, in the short term it'll make some of you redundant, with the 'more productive and creative' picking up their workload until the bots can finish the job. Sounds good.

My understanding is most server farms are connected to dedicated nuclear power plants anyway, so power consumption isn't an issue. Heat dissipation? Yeah, that might be an issue.

Heat and power are the same issue. The conservation of energy means that power in is power out, and the power out is heat that needs to be dissipated. A rule of thumb for data centres is that every dollar you pay in electricity for the computers, you need to pay another dollar in electricity for cooling. If you want high density, then you hit hard limits in the amount of heat that you can physically extract (faster fans hit diminishing returns quickly). This is why AMD's presence in the server room went from close to 100% to close to 0%: Intel was much better at low power.

Comment Re:Intel 10nm != Other Foundry 10nm (Score 1) 104

Intels problem is that it cannot sell FAB time because they are vertically integrated

This is true. Intel will fab chips for other people, but they've had very few customers because everyone knows that the priority customer at Intel fabs is Intel and if yields are lower than expected it won't be Intel chips that get delayed.

Intel builds a FAB and runs its next gen chips off of it for a few years, then they are stuck looking for something to do with the FAB when it is no longer current-gen

This is simply not true. Slashdot likes to think of Intel as a a CPU vendor, but that's actually quite a small part of their business. They make a lot of other kinds of chip and a great many of these don't require the latest and greatest fab technology. This has always been a big part of their advantage over AMD: they have products that will use the fab for 10+ years, so they can amortise the construction costs over that long a period.

TSMC's revenue is now approaching Intel's, and unlike Intel they can keep all their FABs busy making money, so the outlook for Intel is grim without a serious restructuring, which they are doing (see recent massive layoffs, and bullshit marketing about their new "cloud strategy")

This is the important part and is where the ARM ecosystem has an advantage over Intel. No single processor vendor has to compete head-to-head with Intel. As long as the total size of the ecosystem is large enough, the foundries can invest in process improvements.

Comment Re:ARMing servers. (Score 2) 104

AMD had a unique market opportunity to build up a good manufacturing base w/ quality fabs for their CPUs, but didn't. Intel gave top priority to their fabs, and are the standard

AMD spun off their fabs for precisely this reason. Building fabs is insanely expensive and the only way to do is to amortise the cost over a lot of chips. Even at its peak, Intel was producing 4-5 times as many CPUs as AMD and had a load of lower-end products (e.g. network interfaces) that they'd start using the fabs for once they were a generation old. There was absolutely no way for AMD to compete head to head with Intel in fab technology, because they couldn't get the economies of scale.

This does; however, highlight just how bad Intel is at CPU design. AMD has been able to achieve rough parity for decades (and been ahead a couple of times, with the original Athlons and Opterons) in spite of always being at least one process generation behind in fabrication technology.

Comment Re: It takes a LOT of cache and very clever data p (Score 1) 104

Linked lists are just traditionally implemented linked lists. Hash tables are just traditionally implemented hash tables

Linked lists suck for caches, but hash tables don't have to. There's a trend for libraries to provide things like hopscotch hash tables as the default hash table implementation and these are very much cache aware. The real problem is the trend towards languages that favour composition by reference rather than by inclusion, which means that you do a lot of pointer chasing, which is very bad for both caches and modern pipelines.

I think that this is less of a problem in Paris, but it's crazy in some other places. I used to live in Swansea, and for the last few years I lived there the cost of a day ticket was less than most fares (which the drivers knew, so they'd give you the day pass if you asked for most things). At £2.30/day, it wasn't too bad, but for 3-4 of you it was often cheaper to get a taxi. We went back a few months ago and it was cheaper for one person to get a taxi for shortish hops than to take the bus and the cost of the day tickets had gone up enough that it wasn't worth it.

The city council had spent millions remodelling the city centre to allow larger bendy busses when I was there. I never saw one more than 50% full and apparently a year or two ago they discontinued them. If they'd spent the same amount of money on more frequent, subsidised, minibuses, treating it as infrastructure that encourages people to do things that raise tax revenue rather than as a profit centre, then they'd have had far more people using public transport. Instead, privately owned bus companies have made a lot of money and it's now at a point where it's cheaper to drive than to take the bus.

Every week I drive to the supermarket and pick up 20-30 kg of stuff[*].

Why do you do this? I haven't done a big supermarket shop in person for over 10 years. It takes 10-20 minutes to drive each way, an hour wandering around the shop, I have to queue for the checkouts, and it's just a horrible experience. All of the major supermarket chains deliver and it takes about 10-20 minutes to do the shop online (5 minutes for a routine shop where I'm just adding stuff from my favourites) and then it's delivered to my door, by a van that's delivering to a dozen other people on the way.

I'm doing pretty well just to walk through the store and COLLECT the stuff. And no, nobody will deliver it, even if I had two pennies to rub together to pay them with.

Delivery from most supermarkets here is free and even from the rest it's far cheaper than the cost of driving there, even if you don't factor in the cost of your time.

I thought the game looked okay (especially for a one-hour thing), but then I saw what he'd actually had to do. The things that were done for him:
  • Drawing the game board.
  • Collision detection between ball and player, goal, and walls
  • The bounce logic.
  • Events delivered for the buttons.
  • The mechanic for introducing a new ball into the game.
  • The score management. This is like those lego sets that have about half a dozen pieces and can be quickly assembled into a single design of spaceship. Yes, sure, you've built something, but there was little creativity or effort involved. It's not a bad learning tool (and for something that expects people with no programming experience to get something done in an hour, it's fine) but if he doesn't realise how much harder all of the pre-defined bits were to write than the simple logic for gluing them all together then he's now dangerously ignorant.

There was a lawsuit against Apple for the original iPod for a similar reason. Steve Jobs was mostly deaf, so insisted that he be able to hear the sound, so the maximum volume was loud enough to be dangerous. Airline in-flight entertainment systems are the worst: they give you crappy headphones so that you have to turn the volume to max to hear anything if you use them, but if you buy a decent set of noise-cancelling ones then you want the volume down at around 20-40%. This is all fine, until they do an announcement, when they pause the movie and slam the volume up to 100% with no warning.

After six months, he admitted that he'd gradually been having to turn up the volume to be able to hear the music clearly. I've been hesitant around headphones since then and as a result I can still hear the bats when they fly along with me when I cycle home.

Comment Re:Glitchless streaming. (Score 2) 158

This is not something that network neutrality prevents. QoS is completely allowed. If something on the customer's endpoint (or the remote) marks its packets as more sensitive to bandwidth, latency, or jitter then you are completely free to put them into different queues that priorities one or two of those attributes at the expense of the others. The only catch is that you must do the same for all traffic marked in such a way, irrespective of the remote endpoint. If you offer a VoIP service and mark its traffic as being low bandwidth, but being very sensitive to latency and jitter then you can't special-case this and make sure that the experience for your customers is better than a third-party SIP provider or Skype. Similarly, you can't launch your own video streaming service and give it a bigger share of the bandwidth and you can't take money from Hulu or Netflix to prioritise their traffic over their competitors.

It went downhill once they started sending out CDs. Back in the day, AOL and Compuserve would send out their client software on floppy disks (one initially, two later). It wasn't until very late that they started popping out the write-protect slider. I'd call them up every few weeks as a child (freephone number) and ask for a trial pack. Most of it went into the bin, but I'd reformat the disks and they'd be good to use.
