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.

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 2) 269

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.

Electric cars wouldn't use half the country's electricity, passenger vehicles' share of total energy consumption is much smaller than that. But I don't disagree with you that it's bad to waste power. Still, for a potential EV consumer whose turned off from EVs because they're lazy, if the choice is between "waste 20% more electricity" and "keep driving a gasoline car", the wireless EV is still the much better option.

You act like there's no research papers on this subject. There have been tons, and the conclusions in each case are the same:

1) CO2 emissions would decline even on the US's current grid (which is, I should add, getting cleaner every year, while the amount of emissions associated with oil production keep rising)

2) On a generation basis, every region in the US has enough space capacity for a full switchover of the passenger fleet today, without any new plant construction, except the Pacific Northwest. Most charging is done at night when most power plants lie idle, but the Pacific Northwest is an exception because their heavy use of hydro means time of use isn't important, only net consumption.

3) The only thing that there's not enough of at present is simply local distribution capacity, to peoples' homes.

Of course, that's for a complete, instantaneous switchover, which is of course an impossiblity. Your average car is driven for about two decades before it goes to scrap, only a small fraction rotate out of service every year. And that's assuming that everyone bought EVs as replacement, which if course is an impossiblity because even if everyone was suddenly sold on the concept of EVs it'd take a decade or more to ramp up production to that level. And of course everyone is not suddenly sold on the concept of EVs. You're looking at maybe a 30-40 year transition time period here. If power companies can't keep up with a trend that's stretched out over the scale of several decades, they deserve to fail.

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.

Yeah, what evildoers, giving Russia a slap on the wrist for the petty offense of invading and taking over part of another country that had insolently decided to no longer be under Russia's thumb. Next up, the evil tyrants in American and Europe will send Putin a sternly worded letter! Maybe he won't even get a Christmas card from Biden this year!

If you tell me that the Earth is going to change for the worse, and there's nothing we can do to stop it, then my response is we shouldn't try. We should instead work on how to survive the change. No reason to waste resources trying to stop something that can't be, spend them on dealing with it instead.

Likewise if you tell me Earth is doomed, and there's nothing we can do to stop it, then my response is that we should just not worry about the future at all, and enjoy what time we have left because there isn't anything else to do.

However if you tell me that we are creating a problem, but we can fix that problem by changing what we are doing, then I'm interested in hearing what you propose we do, what it would cost, how it would mitigate the problem, etc, etc.

If a problem is solvable then it makes sense to talk about what it would take to solve it. If a problem is just something we can't do anything about then we shouldn't worry about trying.

Indeed it does. I haven't published yet, but I detected one a few days ago (I work out of a valley in Iceland). I observed the brown dwarf in question (right ascension 08h 55m 10.83s, declination -07 14 42.5") and detected a large, earth-sized body occluding the star during my brief observations.
