Here's an A+ reference/tutorial for anyone looking for a "not for dummies" version of rigid body dynamics: http://www.digitalrune.com/Portals/0/Documents/A%20Unified%2... (Had to google for a fresh link; unfortunately this doesn't seem t

If you don't care about being detected, why not just use a boat?

Speaking as someone who knows nothing beyond what you'd find in a Tom Clancy novel: The inability to quietly hold still is kind of a deal-breaker for almost all military & many research uses, isn't it?

I think part (far from all!) of the issue is that you (and parent) are not using the right abstraction: The response body shouldn't be a string; it should be a stream: write_quot(response,"this < should be safe >"); Not p

Instead of mirroring, you could proxy. (Solves "storage"/"mirroring" issue; doesn't solve "nasty stuff served up through your server" issue.) In general, though, there's no way around it, except of course by restructuring gifexplode as a bo

Just a vocabulary/definitions nit: Data modelling (relational, document, data-structure, whatever) is an independent concern from consistency. I may want ACID properties but over a document-structured store, for example, and there's nothing
68.
by crux_ 16y ago
It's an interesting approach, though let's be careful about how we define scaling -- with "full ACID" there are always operations that will make the system go pear-shaped, no matter how cleverly designed the system is. Personally: I like tr
69.
by crux_ 16y ago
Sure, but you can't take advantage of that looseness to scale a collection across a crapton of cheap nodes, either. (Which would be the main driving factor for abandoning ACID in the first place.)

by crux_ 16y ago
Easier, yes. But would it be better? Layering transactions atop a key-value store would be very difficult to do efficiently, for example.
71.
by crux_ 16y ago
Opinion: traditional databases suck and so do NoSQL ones, for the exact opposite reasons. A better solution would be one that gives developers fine-grained control over "scalable and loose" vs "less-scalable and tight", rather than all-or-n

I'd agree with him, given that this statement was about programmers and Java really did open the floodgates for a diversity of programming languages to become accepted, or at least tolerated. The Java language itself, however, is not very

Smalltalk would be a good non-snarky answer and one with some basis in history, although Smalltalk seems to have been a much stronger influence over the JVM than the Java language.

Nit: Halfway to somewhere , but that somewhere ain't Lisp. I'm under-rested and under-caffeinated, but the only thing I can think of that I'd call an intentional similarity between the two languages is the fact they're both garbage collect

How would you structure a program to solve such a puzzle without having it generate and test potential solutions along the way?
76.
by crux_ 16y ago
The constraint-finding is for generating puzzles that are easy, hence the comment about puzzle manners.

by crux_ 16y ago
I believe the above puzzle has only one valid solution.

From the first paragraph of your link: > The solver uses depth first and/or breadth first with constraint propagation to prune the search That would be backtracking. Further, the purpose of many the constraint techniques seem to be aime

That is not true. They're typically designed to be unambiguous (only one correct solution), so in that sense there is always a 'correct' move. However, finding that correct move is exactly as hard, in the computational sense, as finding the

That strikes me as extremely unlikely . I think the complexity class of Sudoko is NP-Complete (a quick google confirms it's not exactly NP but very close: http://11011110.livejournal.com/23221.html?thread=19381 -- complexity is the same

I disagree that fatalities are the most relevant thing to measure. How about a nice simple metric of dollars/kWh, including an accurate accounting for externalities? (I'd also like a pony.)

I'm curious about a couple of things, but also ignorant... so here's hoping for a helpful reply: - How much institutional money (pensions, sovereign wealth, etc) is ending up in VC? (My intuition tells me that the tremendous pressure on the

Keep in mind the date (and origin) of the paper -- expect some vocabulary mismatches. In particular: "run M, in a general form, with unknown values of variables" would probably be called abstract interpretation today. (I'm only fudging be

I'm pretty certain its role is that of a transformer from programs in an intermediate language to optimized programs in that same intermediate language. Hence, a pipeline internal to a compiler. The use of the word "traces" may be the sourc

It's a component for your compiler, not something that would likely exist in a standalone form except for demonstration & research. (For the purposes of above comment, JIT interpreters absolutely count as compilers.) And yes, it's 'just

I also detect a bit of a subtext, specifically: "I can hang with the boys." The startup world is what it is, and getting that message across will help her immensely in finding a job.

by crux_ 16y ago
I don't think it has much to do with human-readability; but rather with: - automatically finding and applying optimizations - with a general approach, rather than a big database of hard-coded optimizations. I'm not sure how (or how well)
