Difference between CR LF, LF and CR line break types?
...floppy disk space were at a premium, some OS designers decided to only use one of the characters, they just didn't communicate very well with one another ;-)
Most modern text editors and text-oriented applications offer options/settings etc. that allow the automatic detection of the file's end-of-l...
Why is Java's boolean primitive size not defined?
... question of how
much a boolean consumes, yes it does
consume at least one byte, but due to
alignment rules it may consume much
more. IMHO it is more interesting to
know that a boolean[] will consume one
byte per entry and not one bit,plus
some overhead due to alignment and for
the s...
Why must we define both == and != in C#?
...ss are equal.
While you can't create a class like this in C#, you can use one that was compiled for .NET. It's obvious it will use our overloaded operator for == So, what does the runtime use for !=?
The C# EMCA standard has a whole bunch of rules (section 14.9) explaining how to determine whi...
List of lists changes reflected across sublists unexpectedly
...fix it, you need to make sure that you create a new list at each position. One way to do it is
[[1]*4 for _ in range(3)]
which will reevaluate [1]*4 each time instead of evaluating it once and making 3 references to 1 list.
You might wonder why * can't make independent objects the way the list...
git - skipping specific commits when merging
..."master", for instance, you can do this. It requires some work---- as mentioned above, the usual use case is to merge everything from a branch--- but sometimes it happens that you made a change to a release version that shouldn't be integrated back (maybe that code's been superceded in master alread...
Delete all tags from a Git repository
...
It may be more efficient to push delete all the tags in one command. Especially if you have several hundred.
In a suitable non-windows shell, delete all remote tags:
git tag | xargs -L 1 | xargs git push origin --delete
Then delete all local tags:
git tag | xargs -L 1 | xargs...
Sort points in clockwise order?
...lgorithm you like, but use special comparison routine to determine whether one point is less than the other.
You can check whether one point (a) is to the left or to the right of the other (b) in relation to the center by this simple calculation:
det = (a.x - center.x) * (b.y - center.y) - (b.x - ...
Visual Studio: Is there a way to collapse all items of Solution Explorer?
I know that I can use Arrow Keys to collapse items of solution explorer one by one, but I would like to know if there is a way to collapse all items with only one operation. I want to know it because, today I have a solution with 6 projects that have at least two hundred files and if I try to coll...
Printing everything except the first field with awk
...
$1="" leaves a space as Ben Jackson mentioned, so use a for loop:
awk '{for (i=2; i<=NF; i++) print $i}' filename
So if your string was "one two three", the output will be:
two
three
If you want the result in one row, you could do as follows:
awk '{for (i=...
