Java's Virtual Machine and CLR
... VM's, with no notion of "registers" like we're used to seeing in a modern CPU like the x86 or PowerPC. The evaluation of all expressions ((1 + 1) / 2) is performed by pushing operands onto the "stack" and then popping those operands off the stack whenever an instruction (add, divide, etc) needs to ...
How to read a large file - line by line?
...htop to see that with plain old sequential pandas dataframe.read_csv, 100% cpu on just one core is the actual bottleneck in pd.read_csv, not the disk at all.
I should add I'm using an SSD on fast video card bus, not a spinning HD on SATA6 bus, plus 16 CPU cores.
Also, another technique that I disc...
Why doesn't C++ have a garbage collector?
... responsiveness or server loading?
should it use lots of memory or lots of CPU?
C/c++ is used in just too many different circumstances.
I suspect something like boost smart pointers will be enough for most users
