Comment Re:GPU? (Score 4, Informative) 182

There are three models. The i5/8GB and i7/16GB models has GTX 965M w/ 2GB mem.
The i7/32GB model has a GTX 980M w/ 4GB memory.

Note that NVidia's mobile GPUs in that generation (900-series, "Maxwell" architecture) are lower-specced chips than the non-M desktop chips.

Meanwhile, there are laptops out with NVidia's next generation of GPUs (10-series, "Pascal") and those do not have different chips in the mobile GPUs, they are only binned and clocked slightly lower, not as a significant difference.

Comment Re:Worst keyboard ever (Score 1) 44

Razer's marketing is full of hyperbole, often bordering on outright lying. Many of their statements are obviously made to be misinterpreted so as to make their products appear to be more interesting than they really are.
They are a dishonest, shameful company.
Never mind that their products are more flash than quality. Their conduct is reason enough to avoid them.

Anyway, the reason why Razer moved from Cherry MX to Kailh for their keyboard switches has more to do with Cherry's supply problems a couple of years ago. They were just too popular.
Other keyboard manufacturers, such as Cooler Master have said that they had to halt production now and then because they just couldn't get enough switches.
Before the resurge in popularity, Cherry made them mostly for customers who needed to manufacture keyboards for special applications.
Remember, Cherry's MX switches are not new: they have been making them since the 1980's -- and some of Cherry's manufacturing machines are that old and some more recently produced switches therefore exhibit more friction than switches that you could find in NIB keyboards from the '90s. Cherry seems to have improved their manufacturing a bit in the past couple of years though.

The IBM Selectric's has a lineage which goes back at IBM to the Electromatic typewriter in 1929 which IBM bought in 1933 and kickstarted their typewriter division.
That one had circular keys, the "Carriage Return" key being slightly larger and to the right of 'P' and slightly down. It then stayed at the same position on IBM's typewriter up to the 1961 Selectric.

Before the Electromatic, the Blickensderfer Electric from 1901 had its "Line" key in the same position but I can't find any info on whether that one was ever mass-produced, as it was intended.

I am curious to what other electric keyboards you might have seen that were produced before 1929.
I know that early Teletype keyboards tended to have separate Carriage Return and Linefeed keys, but those were usually in the same positions: rightmost at the home row and above.

You do realize that the Koch brothers can do what they do because they make a ridiculous amount of money on fossil fuels.
While relatively small for them, compared to what they make, for the rest of us it is a huge amount of money that the use to fund "think-tanks" and other lobby groups and for "campaign contributions" (I.e. bribes) to US politicians.

Comment "3D" ruined it for me (Score 1) 342

The biggest reason I don't go to movie theatres much any more is that the studios and theatres insist on showing them almost only in "3D" - which looks like a blurry dark mess.

"Real-D" is total crap, not being able to project at proper brightness and with too much "crosstalk" between the eyes. The only mildly barely watchable 3D tech is IMAX 3D, but for which there is only one theatre in the whole country where I live (and it has been open for less than a year) and which costs twice as much as a 2D ticket (when they are available...).

But even that does not work well. Stereoscopy at a fixed depth is straining on the eyes and they can't adjust fast enough when there are fast movements, making everything a blur.
Many movies tend to mess up the scale for bigger effect, for instance making large structures look like tiny plastic models balancing at the tip of my nose -- and that just breaks the "suspension of disbelief", reminding my brain that I am watching a movie. When the framing and perspective instead is natural, such as they are in wide shots, the 3D effect is often so small that it does not add anything.

So, give me 4K projection in 2D, in a large theatre with a good sound system! That's how you compete with watching a month later at home. Even if I watch only a DVD on a 32" TV, that still gives me better image quality than in a 3D theatre.

Forget food and drink! I don't want my movie experience ruined by loud chewing noises in my neck and acidic smells.
But DO organize midnight premieres of new blockbusters, where the biggest fans and the devout cosplayers (including me) show up. Those have been some of the best movie experiences of my life.

Comment Re:Software isn't enough, hardware must change (Score 1) 531

At the really low level, what needs to be in the language and what needs to be in the hardware is not set in stone. Microcode is a language, as is the x86-64 ISA and LLVM intermediate code.
Bounds-checking is still a software problem: every array descriptor used by bounds-checking code would still have to be set up by software.
Bounds-checking could (theoretically) be done safely by a compiler of a safe language at some level, if programs were required to go through that compiler.

The problem is that systems today are made for C as the lowest common denominator, and C's programming model is quite permissive.
You can't bounds-check true C in software or in hardware. Doing so and allow pointer arithmetic is hard and you would in effect enforce programs to be in a language that is a subset of C.

Ivan Goddard of Mill Computing has held a few lectures about their novel CPU architecture. In almost every lecture and now and then in the forums he mentions that this or that design detail in the architecture was chosen only so that they could support C's programming model - and that they would have preferred to do it differently.

Comment True 4K = 4096 (Score 4, Informative) 147

None of these consoles is actually 4K.

The term "4K" is originally the name of a cinema standard, which has 4096*2160 pixels.
A 4K image is either 4096 pixels wide or 2160 pixels high (or both), but a 4K screen must have the full 4096*2160 to be compliant to the standard.

The television standard's real name is "Ultra High Definition", abbreviated as "Ultra-HD" or "UHD". It is only 3840*2160.
Some 4K images do fit inside that, but not all. A UHD screen is therefore not a 4K screen.

A "4K TV" is just a marketing term to sell UHD TVs, because it is in the "same order of magnitude as 4K" or "about the same as 4K".

Real 4K monitors do exist, but they are often very expensive, and they also tend to have better support for the colour space in the cinema standard.
The only somewhat affordable screen I know of that is 4096 pixels wide is the one inside of the late 2015 21.5" Apple iMac, at 4096*2304 pixels. It even has support for cinema colour space.

Uber is not a tech company, whatever they claim.

Sure, their business may be driven by an app and a server "cloud" backend - but so do lots of other businesses. It is nothing special about it - and it is definitely not nerdy.

So please, Slashdot, please stop giving this cheap taxi service more free publicity!

Comment Re:Hey Apple lawyers (Score 2) 761

I would not be too worried. Bluetooth radiates about one thousandth of what a cell phone radio does.
I would be more worried about those who talk on the phone all day without using a headset, text constantly or stream music over the Internet.
Cell phone radios don't usually shut off between each data packet. This means that they will continue to radiate for a while even after you have e.g. received or sent a text, albeit at progressively lower levels. The shut-off delays are in the radio protocols and defined by the cell phone operator - not Apple.
