What is the difference between active and passive FTP?
...rties.
In passive mode, the client establishes both channels. We already know it establishes the command channel in active mode and it does the same here.
However, it then requests the server (on the command channel) to start listening on a port (at the servers discretion) rather than trying to es...
What is a reasonable code coverage % for unit tests (and why)? [closed]
...The first programmer is new and just getting started with testing.
Right now he has a lot of code and no
tests. He has a long way to go;
focusing on code coverage at this time
would be depressing and quite useless.
He’s better off just getting used to
writing and running some tests. He...
The Use of Multiple JFrames: Good or Bad Practice? [closed]
...Swing apps. For the most part, I did it in the beginning because I didn't know any better. However, as I matured in my experience and knowledge as a developer and as began to read and absorb the opinions of so many more experienced Java devs online, I made an attempt to shift away from the multiple ...
What is the most ridiculous pessimization you've seen? [closed]
We all know that premature optimization is the root of all evil because it leads to unreadable/unmaintainable code. Even worse is pessimization, when someone implements an "optimization" because they think it will be faster, but it ends up being slower, as well as being buggy, unmaintainable, etc...
What does MVW stand for?
...but over time and thanks to many refactorings
and api improvements, it's now closer to MVVM – the $scope object
could be considered the ViewModel that is being decorated by a
function that we call a Controller.
Being able to categorize a framework and put it into one of the MV*
bucket...
Try-catch speeding up my code?
...ll of us, the problematic code generation path is avoided when the JITter knows that the block is in a try-protected region.
This is pretty weird. We'll follow up with the JITter team and see whether we can get a bug entered so that they can fix this.
Also, we are working on improvements for Ros...
Is there a Public FTP server to test upload and download? [closed]
...url. Visit here and read properly before use. Good luck...!
Edit: link is now dead, but the FTP server is still up! Connect with the username "anonymous" and an email address as a password: ftp://ftp.swfwmd.state.fl.us
BUT FIRST read this before using it

What is the scope of variables in JavaScript?
...passed the point of declaration in the source code. The interim period is known as the temporal dead zone.
function f() {
function g() {
console.log(x)
}
let x = 1
g()
}
f() // 1 because x is hoisted even though declared with `let`!
Function parameter names

What does “fragment” mean in ANTLR?
...with you that this is a meaningful example but (imo) only for who already knows what the fragment keyword means. I find it somewhat misleading for someone who is trying to figure out the correct use of fragments for the first time.

Releasing memory in Python
...ere a way to force Python to release all the memory that was used (if you know you won't be using that much memory again)?
No, there is not. But there is an easy workaround: child processes.
If you need 500MB of temporary storage for 5 minutes, but after that you need to run for another 2 hours a...
