If you ask anyone who has been both places, they will tell you that the Trango rescue or the 1977 Bainthha Brakk epic demonstrate far more tenacity and competence against far thinner odds than these Everest scenarios. This statement includ

Because Everest is on the tick list that non-climbers recognize and because a lot of the lower mountains are much, much harder and nobody will guide them. There is a reason Gasherbrum IV has only been climbed four times (five if you count

I call bullshit. The problem is that certain mountains, notable the "seven summits", most of the 8000m peaks, and a few others such as the Matterhorn, Mont Blanc, and Rainier are overrun by people who are completely clueless. These aren't

Perhaps we disagree about the term "static compilation". SBCL and other lisp compilers read a source file and produce native code which is then executed. If certain dynamic features are not executed, then the compiler (also part of the ru

2. How is a string read from the terminal fundamentally different in Lisp than in Python? How is (eval (read-from-string "(anything here)")) different from Python's eval('anything(here)') ? Just because it's possible to buil

1. I was replying to your statement that eval() required an interpreter. My antagonism was mostly in jest since I vaguely remembered your name, but I also believe in discussions without arguments from authority. 2. Lisp can eval a string th

Evidently you are not familiar with how many Lisp compilers work. You don't need an interpreter anywhere, just a compiler. Note that eval(), as much as it makes sense in the C language, can be implemented in C too (inject the text into a s

you don't get a 2nd chance to design an API I think that is exactly the author's point, at least if you think that the best way to get to the Right API is to "think about it really hard" instead of "write a bunch of crappy prototypes".

Doubling the clock rate without also doubling memory bandwidth and halving latency is likely to bring less than a 71% speedup on that chess program.

It would be fantastic if I could simply click on the equation and have a mini text box pop up with the relevant LaTeX code. Emacs' AUCTeX preview mode renders your equations and tables within the emacs buffer. It's not a PDF, but if I un

> go generic full speed What does this mean? As a simple example, suppose I use malloc to allocate memory (because I don't want to allocate with new which would oblige me to handle exceptions and prevent me from handing ownership over t

It doesn't, Debian testing and unstable are rolling release, and they package -dev separately. Lack of separate -dev packages is something I like very much about Arch because I build enough software that I'm happy to pay the storage cost fo

FWIW, C++ does force some things on you, such as automatically typedefing structs instead of giving you a separate namespace, not warning about multiple declarations with different arguments (because function overloading is a feature), not

Oprofile has been essentially replaced by "perf" ( https://perf.wiki.kernel.org/index.php/Main_Page ) which should offer a superset of oprofile's capability with a nicer interface. This new "trace" looks like it more about system calls, and

Sparse matrix kernels and finite element/volume integration. For bandwidth-limited operations, it is sometimes possible to get better performance by using less threads than physical cores because the bus is already saturated (for examples,

Where N is the number of physical cores? I do not use hyper-threading (it tends to be bad for the floating point and bandwidth limited operations that I do), but usually find minimal compile times at N+1 jobs (but with little penalty for s

$22 was not salary, it was some estimate of the cost of developing on the GPU instance, per day. (Seems high though, should be $2.10/hour * 8 hours unless there are other fees I didn't notice.) In any case, this is very cheap compared to t

Okay, how about removal mid-list with an iterator? Technically that could also be called "splice" after taking sublists, but that makes the term so broad as to be almost useless.

Are you using shell-mode or something else (e.g. term-mode)? Completion works fine in term-mode (in term-char-mode) because it actually uses bash's completion mechanism. In contrast, shell-mode only does line-based interaction with the sh
