Comment That's a pretty silly statement (Score 1) 181

In computer technology, there is ALWAYS something new next year. Yes, there'll be a 14nm shrink next year (or maybe later this year)... but then just a year away will be a technology update, a new core design that is more capable, and of course they'll have more experience on the 14nm process and it'll be better... however only like a year after that 10nm will be online and that'll be more efficient.

And so on and so forth.

With computers, you buy what you need when you need it. Playing the "Oh something better is coming," game is stupid because it is always happening, generally very quickly.

So if you want a 6 or 8 core system, this is what to buy (it's cheaper than their Xeon setups). Will there be a better ones later? For sure. However sitting in neutral waiting for "the next big thing" is silly. Get a system, keep it as long as it is useful, get a new one when you need a new one.

Also hating on this for being enthusiast is silly. Ya it is expensive. So don't get it if you don't need it. However for what it does, it isn't bad. Maybe you need that kind of power. Maybe you need more. Not long ago we had a faculty member purchase workstation with 2x 12 core CPUs. These things cost about $2600 PER CPU, never mind the other hardware to support it. System was over $10,000. However, for the simulations he was doing, it was worth it. I'd never buy that for home, my workloads are much lighter, but I'm not going to hate on him needing it.

Same shit here. Do most users need this? No. Heck most users don't need a quad core. But there are uses for it.

I have never seen RAM as cheap as it is now. When you can buy a 16GB ECC DIMM for less than $200, it is rather wonderful. Our researchers that use big amounts of memory are extremely happy with how much memory they can stuff in desktops and servers for a reasonably price.

Now I'll admit, I don't have a chart of RAM prices, so I suppose I could be wrong, but then I've worked in IT for the last, oh, 20ish years on a continuous basis and spec'ing and buying hardware is a fairly common part of my job.

So please, show me some evidence from two years ago when RAM was half its current price. Right now I see a 16GB 1600MHz 2R ECC DIMM as running about $170, and a 4x4GB 1600MHz unbuffered set running about $150. So please show me some proof that two years ago I could get those for about $70-90 each.

Comment How is that surprising? (Score 1) 181

Have you looked at RAM prices? 32GB of DDR3 RAM is about $300-400 for a 4x8GB set, depending on speed and company. So $600-800 for 64GB. Ok well how about server memory, since you can get servers with 6TB of RAM if you like (really, check HP or Dell). For a 16GB DIMM, which is the largest you can get before the price per GB skyrockets, it is about $160-200. fo $640-800 for 64GB.

So hmmm, looks like DDR4 is right in what other ram costs, plus a bit of a premium since it is brand new tech. What a shock! Who would have every thought it would cost about what RAM costs!

Get off it. Also it is stupid to act like everyone would need to buy the max amount of RAM. That the system SUPPORTS 64GB doesn't mean you have to BUY 64GB. It means that if you need that much, you can have it. If you need less, get less. Most desktops sold today support 32GB in the form of 4 sticks of 8GB DDR3 RAM. Most systems ship with only 4-8GB of RAM, in 1 or 2 sticks. There is nothing stopping you from using less.

You see this even more on the server market. We like Dell R720XDs at work. They support 768GB of RAM. However 0 out of 5 that we have purchased have that much RAM. It is exceedingly expensive, since it needs 32GB DIMMS. However it also means that getting 384GB is much cheaper, since it has the ability to do that on 16GB DIMMS. That said, we have only one system that needs that much RAM. The rest? Between 128-256GB. The rest of the slots sit empty, ready to be filled as our needs grow. Two of the 128GB servers will probably be getting more memory soon.

So seriously, get off it. DDR4 really isn't much more expensive than DDR3, much less than I thought, and memory is cheaper than ever. All these boards mean is if you need a lot of RAM, you can have it.

Comment Because people can twist religion as they like (Score 4, Insightful) 369

The thing is, religious texts say a lot of shit, particularly the major religions which often have a whole lot of text including not just their "official" book but all kinds of other documents that have some measure of authority in their belief system for various reasons. Also because the documents are old, and composed of various collected stories of various authorships, there are generally plenty of contradictions, things that have been shown to be untrue, and so on.

So what really happens is people choose to believe the parts they like, and ignore or reinterpret the rest. They follow the parts they wish and find justifications for not following the others. This happens all the time in all religions. Generally, religious ideology is an excuse, a justification, for a behaviour, not the case. People don't read a holy text and say "Oh, well I have to follow this to the letter!" Rather they have something they want to do and they find a way to make their belief system justify it.

You can see it with things like the "prosperity gospel" Christians and so on. Any even somewhat literal reading of Jesus's teachings shows the guy was the ultimate hippy. All about helping the poor, against material wealth, etc, etc. However, they find a way to justify their views in the bible.

Or the crazy things Orthodox Jews go through to supposedly obey arbitrary restrictions in the torah, while then skirting around them. Like they believe that the prohibition on making fire on the sabbath applies to electricity. However then there are things like ovens with timers greater than 24 hours, so you can have it come on automatically on the sabbath and that's ok. Oh Shabbos Goys, non-Jewish individuals you can hire to do things for you that you are not allowed to do on the sabbath.

Same shit with any of the variants of Islam. What the Koran says isn't really relevant. They'll find a way to make it justify what they want to believe. They can find a way to twist it to allow things that are specifically forbidden, or to ignore things that are required, or whatever.

Comment Something many forget (Score 1) 848

Is that when you buy US Treasuries, you don't actually get anything. They don't send you a magic stone with powers to call in a debt. What happens is there's an entry made in a computer database, a computer that is in the US.

What this means is that the US ultimately has control over the repayment. Now both legally and practically the US is obligated to repay their securities per the agreed upon terms. However, that goes out the window in the case of a war. US law allows the freezing/seizing of assets, and other countries would have no problem with the idea.

So a situation could arise where the US simply declares China's holdings to be invalid and null. So long as the other bond holders are ok with this, and the (US) courts see it as legal, then China suddenly loses over a trillion dollars in investments. They can't just run off and sell them or something, they have nothing to sell. This would tank the renminbi and really screw China over. It actually could have a positive impact on the US, particularly if the other bond holders saw this as a positive (because the US owes less) and trusted that it wouldn't happen to them.

A country selling treasury notes isn't like taking out a loan with a loan shark. It works really different. US securities are:

1) Denominated in US dollars, and thus only worth something if the dollar is.

2) Payable on defined schedules, with no ability to "call in" the loan early.

3) Nothing more than promises to pay from the US government, and thus only valid if the government decides they will pay.

Death stopped being binary some years back (suggest you read medical news) but this isn't about that. This is simple numbers. If device X kills N times out of 100 and device Y kills M times out of 100, where N != M, the lethality of the devices is not the same.

Cops are not doing a good job. Estimates range from 400-1000 unjustified deaths a year. To put it into context, since 9/11, there may well have been 4 times as many unjustified deaths by cops in America as unjustified deaths by Al Queda.

That isn't acceptable by any standards.

Or perhaps if you'd like, I can put it another way. There have been three times as many incidents of manslaughter and murder by American cop per capita of population than there have been incidents of manslaughter or murder in Britain in total.

That number is WAY unacceptable.

Cops carrying guns confer no benefit to those in the area (80% of bullets fired by police handguns miss their target, they don't vanish and they do hit passers-by, sound crew, hostages, etc).

Cops carrying guns confer no benefits to law and order, since alternatives from stun guns to pain rays (microwave stimulation of nerve endings, if you prefer) to teargas (which isn't great but is less lethal than a lump of lead) already exist and criminals are less likely to carry when running is a more practical option than a shoot-out. That has always been the British experience, which is why you now get regular shoot-outs where British cops are stupid enough to carry where you'd previously have had maybe one a decade versus an armed response unit.

Cops carrying guns confer no benefits to the cop, since dead weight can result a cop becoming dead, accidental shootings are very likely to produce retaliation, and "utility" belts stop utilizing when they terrify locals, intimidate visitors, but bolster thugs who gain greater mobility and dexterity from not wearing them.

Look, this is all very simple. Too simple for nutters, perhaps, but simple nonetheless.

First, preventing crime by eliminating prime environmental and psychological causes is a good start. If there's no crime, there's nobody to shoot and nobody shooting back.

Second, preventing cops turning bad by preventing them developing a "them vs us" attitude is essential and you don't achieve that by giving them scrutineering powers and not those they are scrutinizing. It has to be a two-way street to prevent that kind of mindset.

But that requires one additional ingredient to work properly:

Third, preventing cops turning bad by preventing them from being have-a-go heros. They should work with the community, be a part of the community, guard it from within. And, like all good guards, they should NOT be on constant alert. They should be constantly engaging on a social level, not a paramilitary one. If a crime happens, let the criminal go somewhere where there ISN'T a huge danger to others. Inanimate objects can look after themselves, people need a bit more effort.

It is better to let a gang "get away" from the scene, with no bullets fired, be tracked safely and then be apprehended INTACT when it is safe to do so. Going in there guns blazing will cause excessive damage, risk the lives of those supposedly protected and served, and for what? Some carcases. No trial, no determination of the chain of events, no proof even that the dead body is the guilty party. It can't exactly answer questions in the dock, can it?

No, disarm the cops, give them high-res cameras (and maybe girls gone wild t-shirts, I dunno), and let them be what cops should be - good citizens. They are NOT the army, they should NEVER be allowed military-grade weapons, they should deal with matters calmly, quietly and sensibly.

If they're not capable of that, they're incapable of good. Of any kind.

Then it wasn't an accident. Simple as that. People seem to forget that you can build these devices to withstand any force a cop's skull is likely to take, and more besides.

Storage is a non-issue because you don't need to store a lot locally. Local storage can be limited to the time the cop is outside of radio contact plus the time to clear enough buffer that no information is lost. So unless the cop is riding a motorbike in a cage, it's just not enough to create serious issues.

Battery will be a bigger issue. It'll take a lot of batteries to keep transmitting at a decent resolution. However, as cops with guns cause more trouble than they prevent, that's also easy to fix. Sufficient batteries will consume no more weight than a sidearm plus extra ammunition.

Actually, it might not be that bad. With the proposed mandate for vehicle-to-vehicle communication, a cop radio could turn the entire road network into a gigantic adhoc wireless network. You don't need as much power for a short-range transmission. Might as well get some value out of these stupid ideas.

Why would developers want/care about long-term support?

There are a tonne of packages out there that will grab source from a repository and compile in a root jail. You now have binaries for every permutation of dependencies ever produced. Test harnesses (you remember those, the things developers are supposed to use) can give you a list of regressions and compatibility bugs within minutes of a commit.

Long term support encourages developers to be lazy, to presuppose things that may not be true.

Developers are best supposing nothing, testing everything and isolating the conditional (which they should be doing anyway, good software design). If you don't have time to be competent, then you certainly don't have time to be incompetent. So find time.

Gentoo would be ok, except that compiler flags are a bother. I can't use utilities for using profiles to calculate optimal flags when those flags will vary down the dependency chain.

Linux From Scratch is good, it's essentially how I put together my own systems between the last of the MCC builds and the first Red Hat I considered tolerable enough.

Look, I don't expect miracles immediately. Only after the updates from the repository. There simply isn't any reason for so much broken code and suboptimal configs. Not when Ubuntu is run by a billionaire who can afford a few extra hard drives for high-end builds.

Comment Welcome to the free market (Score 1) 341

Where providers are free to gouge and customers are free to... well... complain on Slashdot, but that's about it.

It's only actually free when there's freedom. Freedom to choose between genuinely different providers is a start. If they go to the same tier 2 provider, then the that will define the prices and services, so isn't a choice at all. If they ARE the tier 2, then they're the ultimate source of services and pricetag for all the tier 3s out there.

But there has to be more, since bandwidth throttling dictates bandwidth availability downstream. You can't sell what isn't there - unless you're Time-Warner or Comcast, of course. Try that with a physical product ("It'll cost you $elebenty, payable now, no refund, and if it doesn't do what we claim, that's not a lemon, that's the fault of some unidentified someone doing something somewhere somehow and we'd rather screw you than bother them"). So, freedom to know what you're actually buying and freedom to use statuary rights to obtain that product or a refund.

This is actually one reason I'm a little unhappy with free software. It has been telling vendors that it's ok to not provide what is offered. Not so much by actually doing that - free software has been, in general, superb about being up-front about what it can and cannot do, known defects and limitations, etc. More by saying in the license that the producer is entitled to lie through his teeth without consequence. A quick look at Oracle's conduct shows that vendors have paid very close attention to that clause.

Free Software relies on there being a viable alternative, that users can go elsewhere if dissatisfied. The resilience to fixing bugs in GCC and GLibC, in present and prior administrations, demonstrate that when viable alternatives are scant, such software is too complex to fork or replace unless it gets really, really bad. Which it has occasionally done.

When it comes to cable companies, it's infinitely worse. You're not in a position to run fibre from your home to an alternative tier 2 in another State. Partly because of expense, partly because laws governing interstate activities make it impossible for private individuals, and partly because the cable companies would raise all hell, three quarters of bloody murder and a dash of pint of high water to stop you. Which would not be hard for them, all they need to do is to persuade the tier 2 provider to not sell the capacity. If that failed, they could keep you tied up in knots with the FCC over whether you were an unlicensed telecom operator or not. Mind you, some of you might like knots. I dunno. If all else failed, they could SWAT the people running the cable, get you listed for suspected terrorist ties, or just repeatedly run a backhoe through your cable until you got the message.

You have no choice. You have no freedom. The cable operators have been redefining "monopoly" and "telecommunications" to whatever serves their purpose, not yours, and on multiple occasions. They have been free to do so because everyone likes simplified services and nobody in the States is going to vehemently oppose the "market at work". Even when it clearly doesn't. Not until it is far, far too late to stop things happening.

And we're way past it being too far. It was too far when telecos started replacing copper for fibre at select spots. Supposedly to improve service (which never improved). The reality was that DSL companies competing with the teleco all went out of business where this happened. No great surprise, you can't run DSL over fibre and everyone knew it. It was too late when telephonic "service of last resort" stopped being mandatory in many States. It was too late when ADSL was all private users could buy, SDSL was only sold to select businesses.

It was too late when rival multistate networks got bought up by the Big Telecos with not a murmur from anyone.

It was not because these were fatal in themselves, it's because people had become too stupid and too utterly dependent on being spoonfed by corporate giants (who are far less efficient than any big government ever thought of being, except at defrauding customers). The time for people to learn to think had passed. There wasn't anything left to think about. There were no examples to learn from. All that was left was a self-inflicted oblivion.

It's as if a hundred billion endpoints all screamed out and then fell silent.

The main question is how many channels are allocated for DOCSIS. Each channel gets you about 38mbps of bandwidth, though more can be had on newer standards with 4096QAM (if the SNR is good enough to support it). So if there's 4 downstream channels then a max of about 152mbps total down (upstream is separate).

How many channels can they add? Not sure with current DOCSIS specs, but the wire limits are either 600mhz for old systems, or 1ghz for most new ones. So you cold probably get in the range of 166 total channels or 6gbps or so. Of course in reality, some of those channels have to go to TV and so on.

Now DOCSIS 3.1 is adding new methods for operation and supposedly will pull 10gbps down. Not sure how much of that is tested and how much of that is pipe dream but it is what the spec claims.
