Exploitable PHP functions
... to hide remote code with workarounds like:
include("data:text/plain;base64,$_GET[code]");
Also, if your webserver has already been compromised you will not always see unencoded evil. Often the exploit shell is gzip-encoded. Think of include("zlib:script2.png.gz"); No eval here, still same effec...
Is it safe to parse a /proc/ file?
...l-space buffer during a single read.
I tested that with a program using a 64K read buffer but it results in a kernel space buffer of 3072 bytes in my system for proc_read to return data. Multiple calls with advancing pointers are needed to get more than that much text returned. I don't know what ...
kernel stack and user space stack
...which generally implies that it is 8KB on 32-bit architectures and 16KB on 64-bit architectures—this
size is fixed and absolute.
Each process receives its own stack.
Also the kernel stack contains a pointer to the thread_info struct holding information about the thread.

What is the recommended approach towards multi-tenant databases in MongoDB?
...e for a database is
dbname.0, then dbname.1, etc. dbname.0
will be 64MB, dbname.1 128MB, etc., up
to 2GB. Once the files reach 2GB in
size, each successive file is also
2GB.
Thus if the last datafile present is
say, 1GB, that file might be 90% empty
if it was rec...
Why shouldn't I use PyPy over CPython if PyPy is 6.3 times faster?
...cording to pypy.org/download.html, PyPy needs 4 GB of RAM to compile (on a 64-bit system), not 8. And there's an option on that page to do it under 3 GB if needed.
