Comment Re:Well maybe future improvements (Score 1) 279

GaAs chips have a very high thermal tolerance, temperatures of 250C have been shown to have no impact on MTTF, this is ~250% better than Si. The bigger issue is what do you attach them to, most commonly available PCBs can't handle that, though solutions do exist since I've read about very high temperature GaAs chips used in jet engine monitoring and control.

Doubtful, Ga isn't that rare, we mine ~254t per year mostly as a byproduct of Al smelting, this is fairly small compared to ~54,000t for Si use in semiconductors, but is quite high given the fairly small market for it today. To give you an idea Lithium is slightly less common in the crust but annual production is ~30,000t.

It's definitely slowing down, Westmere EX was 2.6B in early 2011, Haswell EP 5.69B in late 2014 so roughly 42 months to double (Haswell die is ~20% bigger accounting for the 220% count instead of 200%) . A large part of that slowdown though might be economics, Westmere was surely started before the financial crisis and Haswell likely during or after so Intel might have slowed development (especially since on these large parts they don't have any meaningful competition except at the very high end from IBM and Oracle)

Comment Re:Of course (Score 4, Informative) 27

Yeah, or maybe it's because this outbreak killed more people than all previous outbreaks combined. For example this report from 2003 lists 128 total deaths in a remote area of the Congo, at the peak of this outbreak there were more people than that dying per day in Sierra Leone. It's pretty understandable that you don't spend billions on research and development for a drug that might be used on 40 people per year on average but would on a drug that can stop a global pandemic.

The fact is since this is a web vulnerability it will be exploited by XSS attacks from compromised ad networks and also will be included in many exploit kits, you won't have to have remote management enabled for this to be exploited, it will just make it slightly more difficult if you don't.

As to DD-WRT, if they supported the OpenDNS family settings with bypass accounts like the stock firmware I'd consider it, but for me it's a killer feature, and MAC based exceptions aren't an answer because we have shared PC's that may be used by both the kids and adults.

Comment Re:Headphones (Score 1) 249

Yup, my great headphones cost less than my first mediocre center channel (Sennheiser HD598 vs Infinity Primus center), the quality difference between those two is so huge it's hard to describe. If you just want to listen to music by yourself then headphone provide a huge, huge advantage in bang for buck over loudspeakers.

Comment Re:Quad 57 ESLs are insane (Score 1) 249

I love the ESL's, but the amps that can drive them are ungodly expensive, and if you want to listen to modern sources you have to step up to a receiver with pre-outs which further increases the system cost. I still might buy a pair after the kids are done with school =)

Comment Re:Missing option: meets/exceeds environment (Score 1) 249

I have to disagree, my original hifi system for the living room was close to as good as you could get for $1k at the time, Infinity Primus 360 fronts, Infinity OWS for surrounds, the Primus center channel, and a midrange Onkyo receiver. I replaced the fronts with Vandersteen 2CE Signature 2's for $1400 (retail is over $2500, I bought mine from a soldier who was going on long term deployment not long after buying them so they were like new), they're worlds better and just about anyone who's heard both systems can hear and appreciate the difference. The Infinity's weren't bad (in fact I moved them to my bedroom), it's just that I enjoy listening to music as a way of relaxing on the weekends and it was worth the qualitative difference to do the upgrade despite the somewhat high cost (my only other hobbies are cheap). I still want to upgrade the surrounds to Vandersteens to match the fronts, but they're nearly as much as I paid for the fronts and there are very, very few on the used market so no deals to be had, for now it's "good enough" but I am sure that I'd get an upgrade even without changing the room layout.

Comment Re:Unfortunately... (Score 1) 190

60 physical cores + 60 hyperthreading units, kind of like how all the current gen SPARC processors have 8 thread pipelines but two execution units per core. The T5-4 has 64 cores and 128 execution units and the performance is actually pretty close to the DL580 Gen8 so it's not a horrible way to compare systems. Oracle systems go a bit bigger with the T5-8, but my point is that you can go nearly as big with x64, and VMWare allows you to create essentially arbitrary sized containers from the hardware, just like LPARs on SPARC (VMWare 6 supports 128 vcpu's and 4TB of ram per VM so you can use as much of the machine for each guest as you want). The number of workloads that won't fit into a VM on x64 are vanishingly small, so your quip about "That has nothing to do with running a debian VM with 4 x86 cores and 2GB RAM on a Suse Linux or Windows host." is unjustified.

Comment Re:Unfortunately... (Score 1) 190

Then you suck at tuning, it's trivial to get 90% throughput VM versus physical, and with a bit of effort you can achieve 95+% (VMWare actually managed to get over 100% on some Java tests due to scaling issues with the JVM, running lots of clustered smaller instances on multiple machines was faster than running bigger instances or lots of small instances on one machine).
