Limit ggplot2 axes without removing data (outside limits): zoom
If you specify axis limits in ggplot the outlying points are removed. This is fine for points, but you might want to plot lines that intersect with the specified range, but ggplot's range or xlim/ylim methods removes these. Is there another way to…

How many times can a file be compressed?
I was thinking about compression, and it seems like there would have to be some sort of limit to the compression that could be applied to it, otherwise it'd be a single byte.
So my question is, how many times can I compress a file before:
It does…

Why is there still a row limit in Microsoft Excel?
Until Office 2007, Excel has a maximum of 65,000 rows. Office 2007 bumped that up to a max of 1 million rows, which is nicer of course; but I'm curious -- why is there a limit at all? Obviously, performance will slow down exponetially as you…

How do I increase the /proc/pid/cmdline 4096 byte limit?
For my Java apps with very long classpaths, I cannot see the main class specified near the end of the arg list when using ps. I think this stems from my Ubuntu system's size limit on /proc/pid/cmdline. How can I increase this limit?

How to portably find out min(INT_MAX, abs(INT_MIN))?
How can I portably find out the smallest of INT_MAX and abs(INT_MIN)? (That's the mathematical absolute value of INT_MIN, not a call to the abs function.)
It should be as same as INT_MAX in most systems, but I'm looking for a more portable way.

How to reduce CPU limits of kubernetes system resources?
I'd like to keep the number of cores in my GKE cluster below 3. This becomes much more feasible if the CPU limits of the K8s replication controllers and pods are reduced from 100m to at most 50m. Otherwise, the K8s pods alone take 70% of one…
