Given your stated views on OSS philosophy, you could also be one of those "easily led sheep", just in another spectrum, so be careful about what generalisations you toss around. People have different blind spots. Case in point, RMS. He's done very little that can be considered productive after mid-80's yet many geeks blindly follow his preaching without further questioning.
Also, you're talking about the storm in retrospective: Many persons, even geeks here on Slashdot who should have enough physics knowledge and sense of scale, talked down the dangers of the storm with claims such as "It's just a category 1, the media is hyping it up as usual". Also consider the fact that by the time the weather reports that used an aggregate of the euro model and the normal models used in north america were getting spread in media, the ship was already out at sea, so before that, they'd already been fed a lot of "It's just hype, it won't be so bad" etc.
Multiple factors went wrong, the crew being dazzled by the captain just being one of them.
The thing is, for that particular hurricane, even many USN ships, the ones not fast enough to outrun a hurricane that size, remained in port areas, anchored up for hurricane away from the docks. Hell, from what I read on the SA forums, even many USCG ships sheltered from the hurricane, anchoring up-river in the lee of hills if possible.
Other tall ship captains remained with their ships in port, and even warned the captain of The Bounty, but he set out anyway. The problem is, the captain ran with a personality cult crew who was selected based on who was agreeable. and he WAS a thrillseeker. Several experienced Tall Ship sailors refused to work with him. An interview was found where he stated that "you chase hurricanes".
Another reason behind his departure may have been corporate pressure, wanting them down in St. Petersburg as early as possible for cost reasons.
The problem was that the captain had a cult of personality around him, and only chose crew who responded to his projected image of resolve and competence. There was also the factor of feelings of duty etc, that to have stayed on land would have been dereliction of duty, abandoning their comrades etc.(Something many in the US falls for entirely, even in mundane things such as work, easily being conned into working unpaid overtime etc...)
The general consensus on Sailing Anarchy was that the captain was a nut, they even managed to dig up an interview with him where he stated that he chased hurricanes.
To further bring out the point about what I fear in regards to the Ableton Live generation: So-called "epic trailer" music, that is so generic and bland that is all the rage on many esports streams to give a break from the dubshit...
Two Steps From Hell, Audiomachine and similar crap.... I mean, it's so bland and overboosted that it becomes... yawnworthy...
I've visited Stockholms Konserthus, Berwaldhallen and Operan a number of times, and yes, it's a special feeling to experience music in concert halls. Even some metal can be really enhanced there(Such as Therion for example... Or Apocalyptica)
I don't subscribe to that fossilization theory though, because my taste in music has changed with time and I'm in my mid-thirties.
Well, the point he was trying to make was that the pile of OTS+gig-E outperformed the "traditional" approach, and mine was that, no, it didn't. It worked well enough for many, but at the leading edge, pushing SOTA, the traditional shared-memory setups worked far better. And nowadays, if you try to push the SOTA, you need Infiniband or similar, because gig-E and even 10gig-E will choke.
And yes, it can easily be divided into cells, but you still have to pass that data around, and that's where the interconnects etc kick in.
It's the same deal with weather forecasting. Sure, you can easily divide it into discrete cells that can easily run in parallell, parceled out to various nodes... Then you find that you have to pass data between cells, which is why many uni's building "Beowulfs" for cheap weather research eventually spent a lot of money on proper interconnects etc.
Even though I'm not religious, I try to go to various church concerts here in Stockholm, just for the acoustics, and for the organs....
There's NO recording equipment that can capture the full majesty of a huge organ in a church or cathedral. Then there's the mixing and if direct-to-online, encoding....
I fear for when the current Ableton Live generation is in charge of the studios, and not just "musicians" =(
Then you understood it wrong. Seismic imaging is one of those tasks that benefit from SSI etc, and in the absence of that, high-speed&low-latency interconnects such as Infiniband.
The higher resolution of the grid, the more data you need to pass back and forth, at high speed, with as little latency as possible. Each cell needs to exchange data with neighbours, and the datasets are very large.
Back when I started out with HPC, this was one of the tasks where a 128 CPU Origin 3000 SSI with 128GiB shared RAM, beat a 400 Xeon Linux cluster using SCI interconnect, despite the Xeon on paper being faster. With gig-E it would have been even worse for the cluster.
Yeah, this is something I try to hammer into the students I occassionally mentor:
Do not write your code to be written for a specific compiler(Linux and its GCC'isms being a specific example) or even a hard reliance on a library, if it can be avoided. Oh, sure, you can't build a program like a kid builds with Duplo Lego in quite the same way any more, but when done properly it's more likely to be solid.
And why would the Erlang OS not be a particularly good one? Erlang runs a large part of the worlds telecom, both landline and mobile, specifically because of its robustness and feature set. When even AT&T, Alcatel and Nokia have started using Erlang for example, instead of just Ericsson where it was first invented and implemented, it rather indicates that it's good at what it does.
Then you have very damaged hearing, both of you. Out of curiosity, do you both spend a lot of time with headphones/earplugs, and has there been a lot of concerts and such for you?
Now, at age 35, I can hear about 20kHz at 25dB. When I was 18, I could hear 23.5kHz at 20dB(The medtechs had to go and get an oscilloscope to verify that the high-frequency whine I heard before every test tone was actually present. They were highly suspicious of my reaction time to every tone)
K5 was an absolute pile of dogshit, even without Winbond chipsets...
Sure, if you got a system with a K5 to actually stay stable, it was fairly fast in Integer apps, as long as you didn't need to hit the caches too hard... And if you did some actual gaming(Quake, Descent etc), or tooled around with 3D graphics in Lightwave or such, you ran into the fact that the FPU performance was worse than crap... Oh, and tended to make the system really unstable too, no matter what chipset. Alas, it was the only PC I could afford back then =(
Given the desire to record 24/7 with devices like Google Glass etc, I fully understand the decision, and even support it.
It's one thing if someone hauls up a phone and snaps a couple of pictures or a short video clip, but recording video and audio constantly, that's a big Asshole act...
On a related note, isn't it funny to see how some geeks who complain about having their privacy violated actually want to do the whole "record everything 24/7", not thinking about the privacy of those they meet?
The irony is that FZ only started having those "problems" a short while after a major publisher bought them, and the content started becoming more bland and "professional".
Eh... Academia tends to have a lot of people who are the epitome of "extremely smart, but not wise at all", living in a sort of bubble. And this one was in theoretical physics, compounding the issue.
"(The reality, of course, is that the gay rights movement has always been in solidarity with women's rights, and only in ancient Greece do we see cultural acceptance of the kind of chauvinism that was being claimed.)"
I wish that was true, but unfortunately, it is not. A friend of mine is bisexual, as is his GF, and they have a daughter together. They've both been subjected to grossly insulting and discriminating remarks from homosexual men and women(I'm amazed that he let the gay man who said "the only valid purpose a woman has to a gay man is to carry the child" leave the house unharmed..... And he said it in front of the woman too....)
At least the Nvidia cards achieve closer to theoretical performance, even with OpenCL.
As for the fglrx+X, then they must have changed a bit lately, because when I tried out the AMD stuff for a client, CCC was a dependency to expose the OpenCL interface. I had to google it to check if it was true, or if I was hallucinating.
And yeah, you apparently agree with me that AMD is horrible when it comes to the I/O and programming. The horrible I/O is a huge chunk of what makes AMD a paper tiger when it comes to GPGPU work....
Nvidia: Easy to use, easy to program for, good I/O capability, good real-world performance, hence their popularity in the HPC world.
AMD: Awesome on paper. However, crap programming interfaces, Short Bus Special design in terms of I/O, and unless something's changed during the last month, it's STILL completely fucking retarted in requiring Catalyst Control Center and X RUNNING on the machine to expose the OpenCL interface(yeah, that's a hit in the HPC world.....)
I'm going with Nvidia or Intel, thank you very much.....
Hell, one of the primary goals of hacking, from the start of computer/network related hacking, was to get hold of someone's username and password, which included keylogging, dumpster diving, conning people to reveal their usernames and passwords etc.

Which was not a software error, as was aluded to by the post I replied to.
The software itself warned that the readings were incorrect.
Which was a pilot error.
The captain had only slept a couple of hours, the two co-pilots had been out partying, doing drugs and alcohol the evening before.
Yeah, this is something I try to hammer into the students I occassionally mentor:

" the realization is that number crunching isn't that important for a lot of applications"
The reality is, it's important for a LOT of applications, but it's in the background. SSL is just one example.
As a VPN gateway for example, I think the Xeon would just smash any figures the ARM cluster could put up, incl watt/connection etc

In a way, that reminds me of the Clinton-Lewinsky "scandal" and some of the extreme reactions....
The "good christians/family values wardens" in the US: "Omg, he's got a mistress!!"
