Yes, there are limits imposed by the implementation. Your answer is given in the bold text in the following excerpt from the C++ Standard. 1. C++ Language Annex B – Implementation quantities Because computers are finite, C + + implementations are inevitably limited in the size of the programs they can successfully process. Every implementation … Read more
For looking at Java processes jps is very useful. This will give you the main class and jvm args: jps -vl | grep <pid>
Probably because of optimizations. Excel 2007 can have a maximum of 16 384 columns and 1 048 576 rows. Strange numbers? 14 bits = 16 384, 20 bits = 1 048 576 14 + 20 = 34 bits = more than one 32 bit register can hold. But they also need to store the format of the cell (text, number etc) … Read more
For lossless compression, the only way you can know how many times you can gain by recompressing a file is by trying. It’s going to depend on the compression algorithm and the file you’re compressing. Two files can never compress to the same output, so you can’t go down to one byte. How could one … Read more
First off, see How Big can a Python Array Get? and Numpy, problem with long arrays Second, the only real limit comes from the amount of memory you have and how your system stores memory references. There is no per-list limit, so Python will go until it runs out of memory. Two possibilities: If you … Read more
Every SQL batch has to fit in the Batch Size Limit: 65,536 * Network Packet Size. Other than that, your query is limited by runtime conditions. It will usually run out of stack size because x IN (a,b,c) is nothing but x=a OR x=b OR x=c which creates an expression tree similar to x=a OR … Read more
Hadley explains this on pp. 99; 133 of his ggplot2 book (1st edition), or pp. 160 – 161 if you have the second edition. The issue is that, as you say, limits inside the scale or setting ylim() causes data to be thrown away, as they are constraining the data. For a true zoom (keep … Read more
on mac, you probably using mongodb for development purpose. If yes, then you can ignore this.
It depends on your filesystem. I’m going to assume it’s ext4: The maximum number of files is global, not per directory, and it’s determined by the number of inodes allocated when the filesystem was created. Try running the following command to see the number of inodes per filesystem. $ df -i Filesystem Inodes IUsed IFree … Read more
Check the file /etc/security/limits.d/90-nproc.conf as this is likely overriding your settings. I wrote about this exact same issue last year http://scott.cm/max-processes-1024-limits-conf/
