GCC compile error with >2 GB of code
...y for example __libc_csu_fini (which is a function) being referenced from _start and the relocation is truncated to fit. This means that _start (the program's true entry point) is trying to call that function via a SIGNED 32-bit offset, which has only a range of 2 GB. Since the total amount of your...
What is the proper way to re-throw an exception in C#? [duplicate]
... throw new ArgumentException("Not enough room in array to copy elements starting at index given.");
_innerList.CopyTo(array, arrayIndex);

That's not the worse code because it's boilerplate and we can probably just copy it from some other implementation of CopyTo where it wasn't a simple pas...
Disable browser's back button
... your application breaks (displays an error message, requiring the user to start over) if the user goes back.
One approach I have seen for doing this is to pass a token on every URL within the application, and within every form. The token is regenerated on every page, and once the user loads a new...

Is there a timeout for idle PostgreSQL connections?
... answer for that, but it's an OK-ish temporary workaround.
Rather than re-starting PostgreSQL to boot all other connections off a PostgreSQL database, see: How do I detach all other users from a postgres database? and How to drop a PostgreSQL database if there are active connections to it? . The la...
How do I force Postgres to use a particular index?
...n accompanying function for filling it up with n rows of random junk. Then start looking at the query plan for different values of n. When you see it start using the index, you should have a ballpark answer. You can also get sequential scans if PostgreSQL determines (based on statistics) that an ind...
How can I list ALL DNS records?
...n, confirming what I'd suspected - it is available but not to me (unless I start setting up my own nameservers). As I look after very many domains it would have been so nice just to run a script to get ALL the DNS entries.
