Comment Re:DDR4? (Score 1) 173

16GB regsitered ECC DDR3 server modules are only $158 according to newegg but at least on the intel side you need a server board and CPU to use them.

16GB unregsitered non-ecc desktop DDR3 modules are another matter. Afaict only one specialist manufacturer has announced that they are making them and when I google the part number they list I don't find anywhere actually selling it. Also from what I have read the standard init code that intel gives to bios manufacturers doesn't support 16GB modules and it is unclear whether it will ever be updated to do so.

Note that regsitered ECC modules can be quad rank while desktop modules are limited to dual rank. So a 16GB server module needs 4Gb chips while a 16GB desktop module needs 8Gb chips. A 32GB server module uses 8Gb chips and costs about $750 according to crucial which IMO gives a clue as to how expensive 16GB desktop modules are likely to be if and when they become available for purchase.

I'm not convinced of that, there may be a handful of apps that are written directly to target wayland or mir but for the most part I would expect apps to continue to use toolkits like qt and gtk which afaict will support multiple backends.

Apps that use x directly or use an older/more obscure toolkit that only has an x backend will be supported on mir and wayland through thier x compatibilty layers.

The thing is when you look more closely you find that most of those processes are spending most of their time asleep. So there is little to be gained from more than 2 cores (one for the program you actually care about, one for the background crap) unless the program you actually care about can effectively spread it's work across multiple threads*.

* There are a lot of processes that have multiple threads but only use one of them at a time to do significant work.

Memory is fairly cheap (though if you really want lots of memory in addition to the cost of the memory itself you have to consider the cost of the platform to accomodate that memory) but cache, particulally the lower levels of cache that are closest to the CPU isn't so cheap, if you have a pointer-heavy workload (e.g. data structures that are mostly cross-references implemented using pointers) then you can fit a lot less of your workload in cache with .64-bit pointers.

For java (which is very pointer heavy) this was so bad that they implemented tricks in the VM so that if the java heap size is below a certain level then "ordinary object pointers" can be stored in 32-bits.

On linux there is something out there called x32 which aims to combine the advantages of the 64-bit processor mode with the advantages of 32-bit pointers but it's unclear if it will ever catch on.

you can fit 32Gb+ in a consumer grade desktop system.

If you had left off the + then you would have been more on the mark. The largest reasonablly available modules of desktop memory are 8GB and the most slots you will find in a mainstream desktop board is 4 (and many boards only have two). If you want to go over 32GB you have to move to the high end desktop platform (and if you want to go over 64GB you have to move to workstation/server platforms).

Enthusiast mobos mostly only have 4 slots anyway.

Define "Enthusiast mobos", there are plenty of LGA2011 desktop boards with 8 dimm slots.

And Intel showed a Haswell-EP system with 3 DIMM slots per channel while they keep saying it's 1 per channel; clearly we haven't gotten the full story.

That's EP not E, it wouldn't surprise me if ddr4 desktop memory only supports 1 dimm per channel while registered ECC DDR4 server memory supports more. Just as with DDR3 the desktop stuff maxed out at two dimms per channel while the server stuff went up to three dimms per channel

Comment Re:Weird Business Strategy (Score 1) 173

It makes sense for a couple of reasons

1: Intel desperately want to stop the portable computing market moving away from laptops and laptop-like tablets towards smartphone-like tablets. To do that they need to get the most power efficient technology possible into ultrabooks and ultrabook-like tablets.
2: Making a design work properly with 2-4 cores on one chip for laptops and mainstream desktops is a lot simpler than making it work properly with 8+ cores and inter-chip links for a server part (and the high end desktop parts are basically server parts with the inter-chip links disabled and overclocking enabled).

It is a pain to the high end desktop users who have to choose between a low end platform and a core design that is a generation behind and as such it probablly cuts into intel's high end desktop sales but ultimately those high end desktop users are a small part of the market.

Java isn't terribly inefficient itself, it's the people who write things for it.

Yes and no, you can write fast efficient code in java but you have to fight the language to do so. In particular java lacks both user defined value types and parameter pass by reference. The obiovus way round this is to just create objects on the heap willy nilly thereby creating a load of extra work for the GC. There are more efficient methods (using paralell arrays, passing in an object purely so the next level down of functions can use it as parameter passing space) but they all make your code uglier and less maintainable.

I don't see any indication that valve is going for the lockdown strategy. Steamos is debian based and has a desktop mode so I can't imagine it will be any harder to install these games on there than on a regular debian system.

You can get personalised plates in the UK (it's a nice little earner for the DVLA) but you can't just choose any combination you want. The plates sold have the same letter/number patterns as regular plates and you are not allowed to use a plate that makes your vehicle look newer than it really is.

The fact that the CRX burns half the fuel per mile of the Camaro, means that there is simply half the carbon to work with so there will be less overall pollution per mile

There will be less CO2 certainly.

Whether you consider that to imply "less overall pollution" depends on how you score the different gassess in the exhaust.

mmm, singapore is an island city state so anyone coming and going is going to have to change modes of transport and presumablly go through border control anyway.

Whereas in most cities you have a more gradual transition from high density city center to lower density suburbs. This means that if you are going to charge people extra for driving in the city centre and/or limit the number of people allowed to drive there you have to draw a somewhat arbitary line as to where "city centre" ends.

There's a 100+ points inspection every two years for all cars older than 4 years, including smog.

Here in the UK the rules on such things are not retroactive. Your car only has to pass based on the emissions requirements that were in place at the time it was made. So if your second car is an older model it likely has worse emissions. I don't know for sure about france but I'd be very surprised if it wasn't much the same.

Then again, if you can somehow afford to park a second car inside Paris (or any major euro/asia town) just for the rare day when pollution is an issue, you probably don't care about the cost of owning said car...

What about people who live in suburbia but work in the city?
