Comment Re:GPUs have limited applications (Score 1) 121

I wouldn't call a modern GPU that constrained really. The only thing they lack is memory protection. It's also a lot easier to program on a GPU ever since the SIMT paradigm came out (i.e. CUDA, OpenCL). Also plenty of modern processors come with a GPU on the same die as the CPU. Like nearly all smartphones for example.

Actually all modern GPU have had memory protection for several generations. The problem GPUs have is that don't generally have full support for demand paging and precise exceptions (SIMT makes that pretty expensive). For example, putting in hardware for highest possible performance and hardware to be able to hit a page fault and be able to clean up and restart multiple threads (that might be communicating or synchronizing states) are two different hardware optimization points. That being said, some limited support for demand paging is generally possible.

People ride "driverless" elevators everyday without shitting or pissing in them. Why would horizontal movement be so different from vertical movement?

I wish I could be more optimistic than you... For example, BART.

Unlike an elevator, to get into a self-driving-taxi you will need to provide a CC#, or an account number linked to your identity. Your behavior in the vehicle will be recorded by one or more $5 cameras. If you soil the seats, your account will be debited, as you agreed when you clicked on the TOS.

Although a CC is probably a deterrent, ask any taxi driver that works the downtown late-night last-call scene, and they will tell you bodily fluids/solids are routinely ejected in their vehicles. Of course these are the same vehicles used in the daytime...

But the simplest way is to copy the Australians and Canadians.

You get a certain number of points for each year of education and experience, a certain number of points for speaking English fluently, a certain number of points for being in an "in-demand" occupation.

If you score enough points, you pay a few grand to uncle sam, then uncle sam asks you to prove you have enough cash to support yourself for a year and enough for a return ticket (in case it doesn't work out) as well as pass a medical test to make sure you don't have the pox, then sign a contract that you won't try to claim welfare till you've paid at least five years worth of tax (for example).

THEN... after all that, Uncle Sam cuts you a green card and in you come.

Within limits. e.g. no more than 250,000 invididuals per year.

THAT works in Canada and Australia and there not the huge indentured servant problem. It's not tied to company sponsorship.

The point system is great for *merit* based immigration, but in the US, immigration advocates are worried that certain categories of people are underrepresented in the immigration quota, thus we have a *quota* based system for each of Family-Based and Employment-Based and Diversity lottery. Within each of these is a preference level (families based preferences favoring children, spouses and siblings, where employment based favoring advance degrees and exceptional ability over simply professionals and investors).

The problem is that because the way the law is structured to embody diversity quotas instead of points, a maximum of non-exempt 7% of immigrants can come from a *specific* country. This pushes many folks from impacted countries to seek alternative non-immigrant visas like the H1B (temporary worker status) which has it's own issues because it wasn't designed for that. The reason H1B works has a loophole in that you can come right away and work whilst you wait for your green-card (if you come on most other non-immigrant visas, you cannot work and/or apply for a green card). This H1B is also overused by the hi-tech job shop. People often conflate green-cards with H1B. For many, there is nothing stopping you from applying for a green-card with your job offer to come to the US (current green-card processing times are generally about the same as H1B processing times).

For a current viewof priority dates for US green cards, we can see that most are current (which means they process green card applications as received and are processed as fast as a massively inefficient bureaucracy can general move which means about 120 days). As expected, the problematic countries are India and China, but as expected EB-1 (the highest preference employment-based category) is current for all countries (including India and China). The worst is EB-3 India (priority date of 22MAR05 more than 10 years) which is the one flooded by the H1B holders hi-tech job shops

I don't expect that most US voters outside of the hi-tech job distortion field think this is too broken. Exceptional people from all countries get green cards as fast as our grinding government bureaucracy can move. Working stiffs wait in a diversity enforcing quota line. Family doesn't have to wait behind employment. We limit the immigration rate to a manageable amount. It works the way they generally want it to work.

Are people actually going to risk being detained at the airport for hours or being put in jail just to attend an Apple Conference. This is not snark. I am really interested if these kind of things held in the US are still viable. I expect to see more North American international conferences held in Canada. I know that most people attending the conference will be light skinned, but still...

Given the number of H1b's in the US that come from countries that would need visa's to enter Canada (e.g., India, China) for a conference, I expect that very few North American international tech conference that expect a large number of US attendees will attempt to hold them in Canada...

Colored contact lenses solved this problem long ago too...

There's actually a side issue here about genetic prevalence, racial attitudes and (especially) ongoing reactionary racial biases. If one can put aside the historical baggage of Aryan theory for a moment, why *wouldn't* we want to save genetically unique features that are possessed by a small *and dwindling* minority of the population, including (but certainly not limited to) red or blond hair, Nordic-pale skin, blue eyes, etc.?

Comment Re:Bioethicist is the easiest job in the world (Score 1) 159

And you think bosses even consider the bioethicist points of view?

That's almost as funny as the implicit claim that research funding is ethically constrained.

Sure, by definition bosses consider a bioethicist's (or other consultants') point of view. They consider it when they hire them and they consider it when they fire them. The employed bioethicist will probably know who paying the bills and what answer the boss wants to hear.

Thus the comment that all research funding is ethically constrained is effectively a tautology. If the research requires funding, it mirror the ethics of the funding.

Comment Bad reporting (Score 4, Informative) 157

This new Java script attack does *NOT* by itself compromise data, but simply allow a way to remotely extract the Address Space Layout Randomization that is currently employed by the OS. It does this by employing a javascript timer to measure page table walk times which are induced by executing javascript that accesses carefully selected offset in large objects (an earlier attempt to do this was frustrated by javascript implementations deliberately sabotaging the built-in high precision timer object). Once the specific ASLR pattern is determined for this specific boot of the kernel, other kernel vulnerabilities that involved direct access to aliased cache and/or memory locations that were mitigated by the kernel doing ASLR can now be modified to target the desired addresses on the target.

It's like knowing how to make key to break into a specific car, but if you use it on the wrong car, it triggers the car alarm and not knowing what car the key it works on. If you magically had a way to map the VIN to the car key, you could make a key that works for that car and steal the car. The car dealers have this mapping, so they can make a key for you, but what someone came up with a way to figure out the VIN->KEY mapping over the internet?

trolleybuses can't overtake one another,

Happens all the time... Most modern trolleybuses (e.g, SanFran and Vancouver) have batteries and/or small diesel engines that allow them to operate a short time off-wire (which can also be used to overtake). Even in older system, multiple parallel paths with switches in strategic locations allowed for express service overtake.

or take alternate routes during road closures.

Okay, that part is true...

Bus companies have a lot of passenger use data that can be used to redo routes...

Although that is theoretically possible, if you've observed the actual process that public bus companies need to go through to change routes (public hearings, legal protests, community outreach, political meddling), and the potential uncertainty on how that affects the farebox recovery rate, you would realize why they don't just change their bus routes to something more efficient even though they have the passenger use data to justify it...
