Comment "equitable pay based on data in the sheet." (Score 1) 1

No you mean they asked for raises. It's almost certain that some less valuable people were getting paid more than many peers and if everyone honestly asked for equitable pay that would result in some asking for a decrease and I doubt that happened. So, we do not strive for our fair allocation, we strive get that much or our greater unfair share. Reminds me of the proverbial children of Lake Wobegone, who are all above average,

Comment " There seems to be precious little..." (Score 1) 150

"...straightforward information about this on the net." Because it's not straightforward. If you are have enough grasp on your requirements to understand the apps you want to use and you are using commercial CAE / CFD codes, your ISVs should be able to give you some guidance about what typical customers are running (how many cores over how many nodes configured with how much ram and storage with what kind of cluster interconnect and MPI message passing etc) for workloads similar in size to yours. If you're actually considering writing your own, please reconsider unless you have some very particular requirements - but if you do, you'll already have a really good idea of what level of parallelization your cluster architecture requires.

Comment By their logic... (Score 1) 190

... saying "our new car is as fast as a BMW" could be restrained due to the unauthorized use of the BMW trademark. I believe this would fall into the category of "fair use" (if it was copyright, I believe there's a similar doctrine for reasonable use of a Trademarked term)
I assume IMAX (the company which I expect I CAN comment on) is worried about the possibility of pervasive VR taking some seats away from theater attendance.

Comment What Real Drone Racing Would Be... (Score 1) 98

Decades from now, they're going to laugh at any early 21st century definition of a drone that meant a remote controlled aircraft that was just smart enough to keep itself in the air without being directly controlled in real time. Real drones get assigned a task and execute it (flying there is a self-managed task).
So.... drone racing would be a bunch automous units that know when to show up at an invisible, but coordinated starting line at a certain time then lunge into a defined course at scheduled race start trying to get to the finish line first after however many laps or course segments were defined. They'll probably want to avoid contact with other racing drones (unless their AI gets good enough to do sneaky things like bumping or interfering with each others airflow) and any obstacles that are part of the race course.
And of course they'll have have 3d surround cameras so media can switch instantly to the view from any racer.
I'd watch it.

Comment We're still in the interval of Heroin Pricing.... (Score 1) 94

Heroin dealers make the first few hits free or really cheap because when you still have a choice, they need to sell you on it. After you're seriously addicted, the price can be raised because you no longer have the ability to say no.
Similarly, even if it means losing money for a while, cloud providers have to make the cost per unit of compute per hour look very attractive and practically give it away at first, so your IT and Line-Of-Business groups at your firm think cloud is much cheaper than all that physical infrastructure and expensive IT staff you've been paying for. However, some day in the next few years, once you and companies like you have closed down your in-house datacenters and laid off most of your IT staff, you'll find the cloud providers don't need to be competitive with that local choice you no longer possess and the cost of cloud will go though the clouds.

Comment You dont' need another language to do this. (Score 2) 386

"To put it simple, this is a language with a built-in code analyzer and it's a pretty tough one: it can catch all the bugs typical of C++ and dealing not only with memory management, but multithreading as well. Pass a reference to an assignable object through a pipe to another thread and then try to use this reference yourself - the program just will refuse to compile. "
Why do we need another language to accomplish those things? Better IDEs, compilers and analyzer tools should be able to all that for existing languages. If you have a better paradigm for expressing algorithms that you think merits a new language, make that case, but complaints in the quote don't need that.

Comment Accuracy of the paper is suspect already... (Score 4, Informative) 134

I don't know what else they are wrong about but in the paper it says: "For example, the Intel Core i7-3720QM processor, which belongs
to the Haswell family, includes 8192 = 213 cache sets, each of which can hold 12 lines of 64 = 26 bytes each, giving a total cache size of 8192x12x64=6MB".
No, an i7-3xxx anything is in the Ivy Bridge not Haswell family but those cache characteristics would be correct for the Ivy Bridge i7-3720QM.
But if it was a Haswell it would be an i7-4xxx processor. So either they meant a last generation IVB processor or a different Haswell than they called out, but what they said is wrong.
Anyone see any other mistakes?

Comment How this should have been prevented... (Score 1) 150

Even if NASA and ESAB had a "miscommunication" (I suspect an unresolved contract issue, which both sides thought the other has accepted responsibility for owning the floor contracting), what should have happened is that the ESAB equipment people, before starting work on the installation should have inspected the floor work they mandated to make sure it was done correctly. If this happened at all, you'd assume someone who notice that the floor has not been recently rebuilt AT ALL and would stop work until that got done. If you say your equipment needs some part of the environment to be a certain way before you can install, presumably you don't do it until it meets spec. So, no matter who else is to blame, ESAB is negligent in proceeding with work if the floor had not been brought in line with requirements.
An alternate, plausible chain of events is that NASA originally, disagreed with ESAB and felt the floor fix was unnecessary in the first place and told them if they wanted to do it, NASA was not going to pay for that. ESAB does a risk assessment, decides there's a danger but it likely will work and goes ahead. Install fails and during resolution, NASA makes under-the-table concessions to make ESAB whole financially if they admit it's their screw-up. This perfectly reflects the difference between govt and corporate fears. NASA fears looking stupid and is probably willing to pay money to avoid that. ESAB is more worried about losing money and can always subtly imply privately to other future customers that it was NASA that screwed up.
