Comment design for stress not minimal conditions (Score 2) 363

Public utilities need to be designed for stress scenarios
beyond their typical design parameters. Texas has done
many things to a minimal level to save money and do it on the cheap.

I know of snow loading problems were discovered at the
Comanche nuclear power plant near Dallas occurred during this.
In a colder climate they would have used a more robust design approach.

TX politicos tried to blame green energy when the truth is a lot closer
to their "build it on the cheap" approach to things that should be
"build to take a beating and keep on working" mentality.

Regulations and requirements exist for a reason. Keep those R&R robust.
Hopefully there will be retrofitting, but it's going to be expensive and time consuming.

Comment Re:Used to design HDD's (Score 1) 270

So I don't know when you used to design HDD's but you are talking rubbish.

not talking 2.5 drives - also the dual port devices are just the electronics and not the actual HDA

historically 2.5 drives are not as cost effective as 3.5 due to the majority were built with 5V only electronics.

my information is a bit out of date, I got out of drives when I moved out of the bay area.

Rubbish?

Eh, WD and Seagate still hit me up to come drink the Koolaid but I am not going back to N CA

Comment Used to design HDD's (Score 4, Informative) 270

No difference between enterprise and home HDD's that I know of.

As for what "hammering and heavy use " of a drive is?

The biggest killer of HDD's is something called the CSS test cycle.

CSS = Contact Start Stop where the drive is booted up, spun up, and then shut down repetitively.

Generally, a HDD sitting there spinning away is not what kill them off,
however turning them on-off-on-off a lot is the most abusive thing that you can do.

I still think WD makes the best quality out there, but that's just my opinion.

just my 0.02 worth...

Comment Re:How about optical interconnect? (Score 1) 156

Already been done between boards, for sure. Limitations of copper connections on PCB is at roughly 20GB/s - although there are arguments above or below that, that is what I have been able to get up to with some heroic measures.
http://en.wikipedia.org/wiki/Titan_(supercomputer)

Optical connections across boards has been done some but its generally not seriously explored due to the overhead associated with getting in-out of optical medium, people tend to just use copper and put more parallel paths in.

Optical inside the chips? Not there yet, something should emerge in quantum computers before we are all dead, right?

Give this a read.

Moore's law extrapolations are hitting the limitations of physics.

As for shrinking transistors?
Pretty meaningless, silicon hit the limitations of the interconnects a while back.

Parasitic capacitance has been the brick wall that people can not get past.

Comment Costs more to do less = Dead at the start (Score 1) 33

From the article:

  Although the boards can become effective adsorbents, he says the method for making the materials may not be as energy efficient and cost effective as for other adsorbents, such as granular ferric hydroxide, because of all the processing steps needed to produce the treated powder.

Conclusion - its dead before its even starts.

Comment Re:Hardly A New Problem (Score 1) 112

Most MPP machines that I am familiar with have a system where the status and functionality of all nodes is checked as part of a supervisory routine and mapped out of the system. Bad Node? It goes on the list for somebody to go out and hot swap out the device. Processing load gets swapped to another machine.

Once the new device is in place that same routine brings that now functioning processor back into the system.

That sort of thing has existed for at least 10 years and probably longer.

Good grief - looks to me like somebody trying to re-write history.

Yeah, reconfigurable electronics exists in many forms.
Whats unique and different here?
Can't see anything without some specifics of what they got.
Reclaims of reconfigurable analog circuits?
Analog circuits and systems tend to be niche and dedicated
(RF front ends, power systems, ADC & DAC's)
and the reconfigurables tend to be in the digital core of the system.
But then isn't that what we got SW for?
