Comment Re:Performance? (Score 1) 81

Your information is highly dated and perhaps your sources are also a bit biased. At any rate, 100x performance hit is stupid wrong.

Static translation was achieving 50-70% native performance rates (measured against clock cycles) with FX!32 on Windows NT for Alpha in the mid 90's. The problem of course has been very well studied since then particularly with the advent of virtualization and the x64 instruction set and the need to enhance the performance of x86 code running on even Intel's own platforms. Furthermore for any particularly glaring issues that are the fault of the hardware -- well it is much more easily tuned today than it once was. A bespoke opcode or extra register to assist in a specific task is no longer a monumental engineering undertaking today -- it is a matter mostly of dev/test/validate.

The approach taken with x64 to support x86 native execution is quite different than attacking the problem with emulation. Is there a performance hit? Certainly, but a hit of 10-20% simply doesnt make up for the fact that you might be able to have an 8 core ARM for the same price and power budget as a 2 core x86 mobile cpu. The applications that lose in this scenario are the ones the rely on raw single thread performance. Certainly some games are in this camp, but many games which make efficient use of threads are not.

Yup. Love it.

Other than it being free, email/text integration, spam call filtering, and a bunch of stuff like that - it does sound similar.

The one thing I don't like about gvoice is that it won't let me talk on my iPad. I rather suspect that's because of Apple, though - not google. So I'll be interested to see if TMobile supports ipad calling/talking.

Comment Re:$20 trillion in debt? (Score 1) 244

I count no less than five blah blah

Three government shutdown hysteria stories, some Rand Paul "war on science" crap and a tangential NASA story from 2007, none of which have any mention of the scale of the deficit or debt. If that's the best you can come up with then I stand affirmed. Thanks.

Comment $20 trillion in debt? (Score 0) 244

So now we're going to have stories about US debt? We've gone for years and years here at good 'ol Slashdot without much mention of the crazy growth in US debt and the chronic deficits we run, year after year, good economy or not. But let Trump get elected and all the sudden we're talking about the debt! Oh crap, spending bad because inflation and debt and stuff!

Google reveals one Slashdot mention of US national debt in Oct. 2008 [1] related to the "Debt Clock" overflowing and needing another digit, and one other story in 2011 about some federal "Debt Reduction Super Committee" [2] that "failed" to come up with any savings. No other demonstrative mention on Slashdot of the $9.3 trillion in debt racked up during the last eight years.

At least we're talking about it again. Hello libtards; yes, the borrow and spend spree has been huge and the US deficit is out of control. I know you missed that for the last couple terms since the "news" sites you frequent — such as Slashdot — never mentioned it to you, but there it is; $20 trillion and counting.

I think this is targeted at the top tier of immigrant talent

If these "top tier" immigrants are unhappy with racist 'murica not compensating them with enough millions of income then they should head back, see if they can negotiate a "social credit score" that keeps them in the good graces of the party, and see if they're any happier with that. We'll be fine either way.

Comment Re:Mandate reporting when antibiotics are prescrib (Score 1) 75

Yes. But we need to be aware that man is not the only source of antibiotics. They naturally occur. We get a good lot of them from plants and bacteria, starting of course with penicilin which we got from mold, and which was already present on salted food and damp environments. What we did was to make antibiotics present in organisms other than their natural sources.

Comment Everything Old is New Again (Score 2) 75

The Andromeda Strain was published in 1969.

The United States has some disease reporting, it started at least 75 years ago before the antibiotic bubble. This CDC Report summarizes the present state of disease reporting, in two pages. We need higher standards of reporting and legal penalties for failure to report.

Comment Re:Beginning of the end (Score 1) 119

Actually, I had exactly the same thought, and that's coming from a background in biochemistry.

It's not "global warming" that I find frightening; it's the schemes people come up with to "cool the planet" (one or two degrees and hello ice age) or "get rid of CO2" (which is to say, plant food -- this is a recipe for famine by reducing crop yields by at least as much, probably about half-again more since starving plants need more water, and cooling reduces rainfall).

So while you got modded funny... it was actually damned insightful.

Comment Misleading title (Score 2, Insightful) 131

The very first line in the linked article:

Apple has said for the first time that it is working on technology to develop self-driving cars.

And in more detail:

The company is investing heavily in the study of machine learning and automation, and is excited about the potential of automated systems in many areas, including transportation,” said the letter from Steve Kenner, Apple’s director of product integrity, to the head of the National Highway Traffic Safety Administration (NHTSA).

The difference is that they have not said they're making cars in the same way they do not make TVs. But they do make hardware/software that will drive your TV - so to speak.

Just as auto makers can make 'carplay' compatible cars, you can imagine they might one day make 'carpilot' compatible cars.

As a fellow scientific programmer, I am curious to some of those "I've read a few outstanding books on the subject since then."

Could you be so kind as to give me a few pointers? Thanks a lot!

Ugh. I knew someone would ask that. I don't actually keep a bookshelf with these tomes.

Oh, good - here's an article that has a few:

Since college:
"Code Complete" by Steve McConnell (2004)
"The Pragmatic Programmer" by Andrew Hunt and David Thomas

A fun book to do with colleagues:
"Seven Languages in Seven Weeks" -

If you're into OO:
"Design Patterns: Elements of Reusable Object-Oriented Software" Gang of four

Not coding, per se, but everyone who works in the field should read and have their boss read:
"The Mythical Man-Month" by Frederick Brooks

The best books from college (I haven't touched in nearly 20 years, but I'm really glad I had 'em back then):
"The C Programming Language" (2nd Edition, 1988) by Brian Kernighan and Dennis Richie
"Compilers: Principles, Techniques and Tools" - the dragon book

Comment Re:Maybe (Score 1) 379

For most development projects, I would agree that going into the nitty gritty can seem like overkill. But, having a core understanding of low level programming can make a huge difference in application performance. The third book "Sorting and Searching" should be required reading for anyone who plans on getting involved with databases, even if they only plan on being a dba.

You can do a lot with high level programming languages, but if you skip assembly or C programming for at least a background on what is happening behind the scenes, it starts to feel more like alchemy than chemistry.

Sure. And I've coded in C (which I think almost has to be true for anyone who has worked in the field for >20 years). And I've written a bubble sort and a quick sort (in college and after). And a tree balancer in college at least. And I just don't feel like I need to slog through a volume on the subject...
