Why, why, WHY would a site think its ok to store users' passwords in the first place?
From what I've read, they didn't store the passwords, only hashes. The passwords that have been released were weak passwords that were easily brute-forced from the hashes.
That said, reinventing calculus is no small feat, and certainly not worthy of mockery. Dr. Tai simply lacks education, which is something that should be addressed in med student curriculum.
Classified status should not be given to a file for the sake of saving the government from embarrassment.
From the above-mentioned document:
Sec. 1.7. Classification Prohibitions and Limitations. (a) In no case shall information be classified, continue to be maintained as classified, or fail to be declassified in order to: (1) conceal violations of law, inefficiency, or administrative error; (2) prevent embarrassment to a person, organization, or agency;
Last time I was at the Pentagon, all of their USB ports were physically disabled - either via breaking the socket with a pair of pliers, or by filling the socket with hot glue. What happened to that mandate?
USB is pretty essential. Macs, for example, have USB ports and maybe Firewire, but no PS/2 connector. If you want to connect a keyboard and mouse, you'll need USB. (Well, that or bluetooth, but security folks usually aren't keen on having radio transmitters in classified machines.)
On the other hand there's a lot of C syntax that is not valid C++.
... uhm... WTF are you talking about. I've been doing dev in C for 20 years and I've yet to see one thing in C that is invalid in C++. I fully admit to not reading the actual language specification, but I call bullshit and would say your problem is with a shitty compiler that either didn't detect the problem you had in C mode or doesn't compile C++ properly.
The fact that you think 'Top Secret' has any meaning outside of a TV or movie show just shows you are utterly ignorant of the situation.
Really, the government doesn't classify things that way.
Top Secret isn't a real classification? Gee, I guess the security folks at my last classified document handling refresher need to update the course materials.
What comes to the real codes you keep repeating is that there is no such thing as a standard for real codes.
No, I said that LINPACK is a poor measure for what people actually do on supercomputers.
Benchmarks are excellent for the true HPC where more and more tasks can be done extremely fast with highly specialized machines. If you need general purpose super computer you must not aim for a top spot in LINPACK.
Uh, what's the difference between HPC and "general purpose" supercomputing?
Codes? Is that what internets are programmed with?
I know you're just being sarcastic, but the HPC equivalent of a program or an application is a code. Google "hpc codes" or "multiphysics codes" for some examples. And for some trivia: the input script for a code is typically called a deck, a term that's been around since the days when the input was handed over to computer operators as decks of punch cards.
These things go through extensive testing on customer codes before they are procured.
Not if you're the first one to get a new type of machine. In that case, the machine is procured with certain promises, and then customer tries to port their codes to the new machine.
That said, 100,000 smartphones would cost about $40 million. Which isn't unreasonable. And it would indeed outperform all of these machines on LINPACK tasks
Yeah, right. Look at the number of cores on the current list: 200-300k. (By the end of next year, it will be approaching 2M cores.) You think your 100k ARM-powered, memory limited smartphones could compete? And with what interconnect? USB? Bluetooth? WiFi? Good luck with that.
The advantage is that, contrary to the arguments of TFA, the test is very representative of scientific and engeneering problems.
No, it really isn't. I work in HPC at a national lab, and our bureaucrats buy these computers based on these benchmark numbers and then expect us to adapt our codes to fit these machines, rather than buying machines that are better suited to the problems we are solving. For example, one of our machines peaked at #2 on the Top500 list, and was essentially useless for real codes. Another machine of ours held the #1 spot for quite a while, and worked well for a small class of problems, but was so limited in functionality that it couldn't even run many of our codes. I've heard similar stories from people using other machines near the top of the Top500.
Real science codes often do not look anything like LINPACK, and the computers that run these benchmarks fast aren't necessarily good for true HPC.
One important difference: mathematically, if f is a function and x is in the domain of f, then f(x) == f(x). This isn't generally true about a "function" in a computer program. (For what it's worth, I know some computer scientists who are very careful to call a subroutine a "function" only if it meets the mathematical definition.)
It seems like this technology's usefulness went out the window years ago whenever nearly everyone started carrying cellphones with cameras around with them at work.
The kind of places that are trying to prevent certain documents from being copied probably already prohibit cell phones and cameras. Where I work, cell phones and virtually all other personally-owned electronic devices must be left outside of the buildings.
Why aren't linux package managers using this instead of just leaching off of college servers and the like?
The problem with using BitTorrent by default is that it's blocked in a lot of corporate and government settings. Where I work, it's easy to download things via http, but due to our strict firewall it's very tedious to use almost any other protocol. Fortunately, we have local mirrors for common Linux distros and a fast connection.
If he has a really poorly designed motherboard and his old cables were really crappy(I.E had NO SHIELDING). The old SATA cables may have been injecting noise into the analog back end of the sound card.
Perhaps that's possible, but Steward is using those SATA cables on his NAS device, so the noise would also have to propagate across his network to the audio system.
On a side note, Steward is apparently making defamation claims against the folks discussing his blog:
This seems like unnecessary pedantry. We're talking about market share percentages as a unit: the change from 40% of market share to 50% of market share is a gain of 10% of the market. The change from 40% of market share to 100% of market share would be a gain of 60% of the market.
I tried to parse it that way, but they're not talking about market share, but rather what percentage of their enterprise customers are using Solaris. (I assume they want folks other than their enterprise customers to be running Solaris, as well.)
I suspect that the person who wrote this memo just doesn't understand math.

Remember when the Cult of Scientology banned its members from viewing critical content or leaked documents, and even distributed a sort of parental-guidance web censor? Can't find the source at the moment, but it was probably around 2008.

Yup, one of my office computers is a diskless iMac that boots from a network server. Works fine.

Isn't Calculus a standard pre-med requirement?
It is an executive order! The entire classification system is defined by a series of executive orders, of which this is the most recent.
If all classified material had a time-table for future release, then classified documents wouldn't contain dirty laundry.
With few exceptions, classified documents do have such a timetable. See Section 3.3, "Automatic Declassification":

Have any of the documents leaked been Top Secret? According the reports I've read, the highest level of classification in these leaks has been Secret.
Then the vendor presumably tests the codes as the machine is developed.
The vendor will test sample codes or validations suites. At many supercomputing sites, the real codes can't be given to the vendor.
What comes to the real codes you keep repeating is that there is no such thing as a standard for real codes.
