POSIX needs to split ENOENT

There is a problem. posix error codes have ENOENT, but this is returned by both open() and opendir(), this means the corresponding string is "No such file or directory", however, what if you were opening a file? Its a bit confusing for a word processor to report "No such file or directory"

The workarounds are not ideal, although GNU objdump and other binutils packages do do it very well. You basically need to use your own strings, and then call open_strerror(err) or opendir_strerror(err) instead of the regular strerror()

The ideal solution would be a new code for directory, although that makes compatibility difficult.


I think this is better than introducting two new codes, so just update opendir() to set ENOENTDIR and reduce ENOENT to be "No such file"


: in debian/ubuntu package filename

As HTTP needs to encode : in filenames as %3a, why don't debian package filenames skip ':' ?



This is actually:

http considered harmful. Browsers should default to HTTPS

If I type in why does the web browser still default to insecure HTTP? protocol? Nowadays, should assume https!

More importantly, should only allow existing insecure http traffic during a transition period. Deprecate HTTP and in a year from now only allow HTTPS connections which are secure.

Business directory phone numbers

I've a Samsung Galaxy S3. What would be great, is if Google could index directly into the address book local businesses.

AT the moment, I need to search for them on google maps, and then manually add them, after I have rang them. Of cause they change their number, and then my contact no longer works. It should be transparent, so if I type "Specsavers Marble Arch", it should search and let me dial directly!

The volume “boot” has only 0 byte disk space remaining?

Why do Ubuntu ship a distro like this?
Manually removing older kernels takes time. Also the initramfs fails because.. there is no disk space left on "boot"..

Surely dist-upgrade should automatically remove all old kernels apart from generic? In addition, "boot" should be a GB large, so this issue never occurs for most users.. I'm running from a 500 GB drive.

dpkg -l |grep linux-image

apt-get remove linux-image-xyz..


Junk mail proposal

I feel the register of electors "no marketing opt in" should be used by all organisations. That's my default decision.

If I've not specifically signed a contract opting in to their specific marketing scheme - don't junk mail me :-)
