git pull from master into the development branch
... when you run the merge. You can insert --no-ff or --ff-only to prevent a fast-forward, or merge only if the result is a fast-forward, if you like.
When you use the sequence:
git checkout dmgr2
git pull origin master
the pull command instructs git to run git fetch, and then the moral equivalent...

Is Fortran easier to optimize than C for heavy calculations?
From time to time I read that Fortran is or can be faster then C for heavy calculations. Is that really true? I must admit that I hardly know Fortran, but the Fortran code I have seen so far did not show that the language has features that C doesn't have.

Find the nth occurrence of substring in a string
....find()). I will also compare with a C extension (_find_nth.so) to see how fast we can go. Here is find_nth.py:
def findnth(haystack, needle, n):
parts= haystack.split(needle, n+1)
if len(parts)<=n+1:
return -1
return len(haystack)-len(parts[-1])-len(needle)
def find_nth(s,...
Websocket API to replace REST API?
...their examples to implement them with websockets. We got it to work fairly fast though. But it does feel like we are going against the flow.
Having said all that, we are going live next week. We got there in time, everything works. And it's fast, but will it scale ?
...
Is it possible to decrypt MD5 hashes?
..., but it's not impossible.
MD5 is a bad hash to use for passwords:
It's fast, which means if you have a "target" hash, it's cheap to try lots of passwords and see whether you can find one which hashes to that target. Salting doesn't help with that scenario, but it helps to make it more expensive ...
Things possible in IntelliJ that aren't possible in Eclipse?
...
It is intelligent, and damn fast. This adds up to a lot of usability features. Traversing to a subclass or implementing class, find-in-path, find usages, etc. happens so fast. Auto-complete happens inline, just a tab will insert it. Auto complete is als...
Passing arrays as parameters in bash
...}"
echo "values: ${ARR[@]}"
}
declare -A HASH
HASH=([foo]=bar [zoom]=fast)
funky HASH # notice that I'm just passing the word 'HASH' to the function
will result in the following output:
indexes: foo zoom
values: bar fast
Since this is passing by reference, you can also assign to the array...
Can you explain the concept of streams?
...hat users can watch / listen to the streamed media file while downloading. Fast-forwarding and rewinding is possible, offcourse withing the buffer. Anyway, progressive download is not live streaming.
Streaming
Happens real-time, and chunks data. Streaming is implemented in live broadcasts. Clients...
Simple explanation of clojure protocols
...tocols have a trivial mapping to JVM/CLI Interfaces, which makes them very fast. Fast enough, in fact, to be able to rewrite those parts of Clojure which are currently written in Java or C# in Clojure itself.
Clojure has actually already had Protocols since version 1.0: Seq is a Protocol, for examp...
