True | grauenwolf | null | Not necessarily. It isn't hard to create an API that can't be used by some .NET languages. For example, marking an event as abstract will make it impossible for VB to implement a subclass.
XNA has another problem, it runs on a platform that doesn't support dynamic typing. That means VB, prior to the most recent version, and all of the DLR languages are off limits. | null | 0 | 1317400389 | True | 0 | c2nt86u | t3_kvbv9 | null | t1_c2nt86u | t1_c2nqk35 | null | 1427668297 | 6 | t5_2fwo | null | null | null |
True | leoel | null | It's ok, my answer was also a bit rough :) but it is only because as technology evolves and it is easier and easier to make graphical applications that "just work", a lot of people, including professionals, seem to think graphics are a simple task with no work involved except for "where do I put this image/line/complex vectorized data, and what size must it be". The fact is, they just have been deceived by the simplicity of modern API, and it can suddenly come and eat them alive (like: why is it so blurry and unreadable when I'm zooming between X% and Y% when completely readable in all other settings ?). I was just trying to make clear that computer graphics have still a lot of good things to discover and improve for the ones inclined to look under the hood. | null | 0 | 1317400399 | False | 0 | c2nt88j | t3_kvtrp | null | t1_c2nt88j | t1_c2nt3fl | null | 1427668298 | 2 | t5_2fwo | null | null | null |

True | jcipar | null | The big one is that last paragraph: Cassandra lets you do column-major storage (at the granularity of a column family). For many applications a column-major data layout is a huge performance win. The two important cases are applications where each row is big, but any given query only cares about a small subset of the columns, and applications that have to filter rows but can't use an index.

I don't really see this guy's point, training one's "algorithmic skills" is very different from exercising muscles -- once you've learned something, you'll remember it for a while, at least in some form. So there is no need for 'consistent' 'frequent' 'workouts'.
And I think it's much better to learn many algorithms of different natures than to concentrate in one narrow field. And it's better to design algorithms yourself than to memorize existing ones.

much numerical analysis is done in a floating point environment unless you need an absurd amount of precision. the problem with arbitrary precision arithmetic is the time cost, and unless it's unavoidable, floats will be used. though that's also the main part of numerical analysis - finding better methods that are more stable. the thing is, in a floating point environment is you can usually find a tolerance to work with where roundoff isn't a problem. | null | 0 | 1317401812 | False | 0 | c2ntfyq | t3_kwf95 | null | t1_c2ntfyq | t1_c2nsx2h | null | 1427668400 | 11 | t5_2fwo | null | null | null |

True | ponnanganni | null | The most important element of my review would be to attempt encapsulating user interaction into a separate class so you would abstract all cout/cin operations to a set of operations with clearer name.
it could look somewhat like this:

void promptUserForValidation(const std::string& message);
const std::string promptForArbitraryInput(const std::string& message);
};

I've been shying away from test sde jobs because I don't want to get pigeon holed into test (I'm a dev, not test damnit), but it's beginning to seem like test in one company is different than test at mine.
Testers at my company mostly run manual scenarios and every once in a while write these test scripts that are very much scripted (dumb coding, really no thought in terms of design or architecture).

True | steve_b | null | Just to add an additional example: What's deceptive about the standard floating point representation is that there exist numbers that can be represented with little precision, like 1/10, in decimal can never be represented accurately in binary (basically it's 0.0001100110011, with 0011 going on forever), as there is no way to express "one tenth" with binary fractions, just as you can't represent "one third" in decimal fractions.
But people are so ingrained into thinking that 1/10 is a low precision number, they assume that 32 or 64 bits of precision is good enough. And it is, until you start use the number repeatedly in computations, and suddenly, when you expected your answer to be "3", it turns out to be 2.99999999999. Not a big deal when calculating positions on an x/y chart, but a big deal when you expect all your debits & credits to line up.
So when doing financial calculations where precision is fixed, but absolute accuracy is mandatory, you use the decimal data types; if you don't have access to those, just use long and do all your computation in pennies (or whatever the smallest unit of currency is), and convert to dollars when displaying data only. | null | 0 | 1317402209 | True | 0 | c2nti2t | t3_kwf95 | null | t1_c2nti2t | t1_c2nt13v | null | 1427668428 | 20 | t5_2fwo | null | null | null |

True | Mikul | null | There was no meeting with anyone on the list that I know of. Since I was 2nd from bottom, I would have probably known. This was one bad manager out of a dozen. I don't hate him too much. He had a nice trait of telling you how to implement something, and when that turned out to be the wrong way, would blame you. The whole team knew about him. At first we ignored him, but would eventually call him on his mistakes in public (as he would to us).
Honestly, I think his biggest and root fault was not telling us anything that was going on further up the chain so we couldn't prioritize properly by preparing for upcoming events. We didn't know management's plans or the constantly changing schedule. Some of this may have been flow down from the PM who was insane. The PM estimated the project at 9 months. My ballpark figure on day one as 3-years. That was 3-1/2 years ago and the project is just winding up... and being shelved. | null | 0 | 1317402359 | False | 0 | c2ntivy | t3_kvo92 | null | t1_c2ntivy | t1_c2nsuz4 | null | 1427668438 | 4 | t5_2fwo | null | null | null |
