What's the best strategy for unit-testing database-driven applications?
...ust hauling your production DB into a test system translates to "I have no idea what I'm doing or why and if something breaks, it wasn't me!!" ;)
It makes sure the database can be recreated with little effort in a new place (for example when we need to replicate a bug from production)
It helps enorm...
Facebook Graph API v2.0+ - /me/friends returns empty, or only friends who also use my application
...an app to find restaurants... a game to find restaurants, etc. you get the idea. So is this REALLY close to games or this is just a way of forcing you to place an app inside Facebook and spending money on their advertisement platform? Who's going to decide what a game is? Who decided that your app i...
What is the difference between a process and a thread?
...s answer is way better than the accepted answer because it talks about the ideal of processes and threads: They should be separate things with separate concerns. The fact is, most operating systems have history that goes back farther than the invention of threads, and consequently, in most opera...
How do I use valgrind to find memory leaks?
... others, so look for one that looks a good culprit and apply some of these ideas:
List out the functions in your code that depend on/are dependent on the
"offending" code that has the memory error. Follow the program's execution
(maybe even in gdb perhaps), and look for precondition/postconditio...
Batch script: how to check for admin rights
...list of applications in the C:\Windows\System32 folder, trying to get some ideas. After trials and errors, this is the dirty (pun intended) approach I've come up with:
fsutil dirty query %systemdrive% >nul
The fsutil dirty command requires admin rights to run, and will fail otherwise. %systemd...
OpenCV C++/Obj-C: Detecting a sheet of paper / Square Detection
...thinning is being used, I don't care from where he took several thresholds idea -- it is just not used here (thus how can it not be a difference ?), the image is resized here, the component measurements are different. "Some dilation-erosion" doesn't give binary edges, otsu is used for that. It is po...
Database design for audit logging
... fields that were edited that you then have to mash up to give the user an idea of what the old record looked like.
So for example, if you had a table called Opportunities to track sales deals, you would actually create two separate tables:
Opportunities
Opportunities_Content (or something like th...
Should a Netflix or Twitter-style web service use REST or SOAP? [closed]
...A totally agree about the question above...terrible question, and about as ideal an example of "subjective and argumentative" as it gets, and certainly couldn't have been more absurd. :P I would make one distinction about SOAP however...I think it fits the bill of "swiss army knife" much better than...
Difference between array_map, array_walk and array_filter
...
The idea of mapping an function to array of data comes from functional programming. You shouldn't think about array_map as a foreach loop that calls a function on each element of the array (even though that's how it's implemented...
In Java, when should I create a checked exception, and when should it be a runtime exception? [dupli
...even Errors).
Additionally, checked exceptions break encapsulation.
This idea that checked exceptions should be used for "recoverable" errors is really pie-in-the-sky wishful thinking.
Checked exceptions in Java were an experiment... a failed experiment. We should just cut our losses, admit we m...
