Making a second call is *extremely* dangerous. The process of `INSERT`ing and selecting the resultant auto-generated keys must be atomic, otherwise you may receive inconsistent results on the key select. Consider two asynchronous `INSERT`s where they both complete before either has a chance to select th... |
As far as I know, GTK TextView doesn't include an undo function. So while I am not familiar with Python's GTK library, I would think it doesn't have one.

Ilkka: I was looking at Wireshark, but from what I could tell, that didn't handle the interception aspect -- only the sniffing and logging. The thing the professor's looking for is to prevent the spams from getting out onto the network.

Thanks, CDV. I'll look into that as well. Good call about the legality check. I've actually been trying to use gnu public license projects so far. |
I think one aspect that defines real-time is that the process is *deterministic* - that is, the application's response time is totally predictable based on the inputs.
Thus, painting with very broad brush-strokes, any app sitting on top of Windows can only be "near-real-time", at best. Doubly so if your app is runni... |

I'm having problems deciding on what is the best way is to handle and store time measurements.

I think the simplest is to just convert user input into a integer number of seconds. So 54:12 == 3252 seconds, so store the 3252 in your database or wherever. Then when you need to display it to the user, you can convert it back again. |
Here's what I've used in past projects:
var myDate = new Date();
var tzo = (myDate.getTimezoneOffset()/60)*(-1);

Doing your own flush()ing sounds right to me - you want to be in control, not leave it to the vagaries of the generic buffer layer.
This may be obvious, but make sure you're not calling write() too often - make sure every write() has enough data to be written to make the syscall overhead worth it. Also, in the othe... |
The Voronoi diagram is just the dual of the Delaunay triangulation. So, the edges of the Voronoi diagram are along the perpendicular bisectors of the edges of the Delaunay triangulation, so compute those lines. Then, compute the vertices of the Voronoi diagram by finding the intersections of adjacent edges. Finally,... |
For that you have to understand the standard IEEE 754 in order for proper binary representation. After that you can use **Float.intBitsToFloat** or **Double.longBitsToDouble**.

Even if it was actually useful for any reason (e.g. variable scope control), I would discourage you from such construct from the standpoint of good old code readibility. |

Option 2 is the correct answer, unless you have a really good reason to add a surrogate numeric key (which you have done in option 1).
Surrogate numeric key columns are not 'primary keys'. Primary keys are technically one of the combination of columns that uniquely identify a record within a table.

It's nice for aggregating feeds, yes, but the other handy thing to do is filtering the feeds. A while back, I created a feed for Digg (before Digg fell into the Fark pit of dispair). I didn't care about the overwhelming Apple and Ubuntu news, so I filtered those keywords out of Technology, which I then combined with Sc... |
For managers:
- the sooner the product is released to the market (assuming it's shrink-wrap), the sooner the company can make money and the better the cashflow.

Lock-in feature set for a short time frame (Scrum/iteration/agile). As the user starts seeing things working, the necessity or lack thereof of features will become more apparent.

Hardware's generally pretty OS-agnostic (at least in terms of Windows flavors) these days. Your only concern is getting drivers for other devices (scanners, printers, IR remotes) that won't work on 64bit and/or won't work on "Server" OSes.

What sort of constraints? I'm guessing foreign key constraints, since you imply that deleting a row might violate the constraint. If that's the case, it seems like you don't really need a constraint per se, since you're not concerned with referential integrity.

Most databases have some sort of time interval type. The answer depends on which database you're talking about. For Oracle, it's just a floating point NUMBER that represents the number of days (including fractional days). You can add/subtract that to/from any DATE type and you get the right answer.
