Comment on Python and poor documentation – urllib2.urlopen() exception layering problems by Mridang Agarwalla

I’m facing the same problem. I could only find the URLError and the HTTPError in the urllib2 documentation. They should add more exlicit instructions.

Comment on Facebook apps in Python and Pylons part 2 by Colin

I replaced the “if not fb.check_session(request)…” line with:

if not fb.check_session(request):
if not fb.auth_token:

I don’t know why that works and the other doesn’t – perhaps there’s something lazy going on as it evaluates the ‘or’.

Comment on tmux, a BSD alternative to GNU Screen by Jim

Second the use of C-z for prefix key (C-z z is easy to type) and I also use C-q and C-s at times (flow control is practically useless these days).

Plus, if you’re using job control that much, you’re doing it wrong. That’s what screen/tmux is for!

I’ve also spent quite a bit of time trying to choose an unused and easily accessible escape key. My final choice is Ctrl-l. The only time I use it is when my screen is messed up, and I want to redraw it, but it doesn’t occur often enough, so pressing “ctrl-l l” is not a big problem for me.

Vince: Like Ramkumar, I use C-z as my escape. I make heavy use of job control, but haven’t found that hitting ‘C-z z’ is particularly more inconvenient than a plain ‘C-z’. (Unlike C-a, which is flat-out awful if one is used to emacs-style navigation.)

Arghh! I specified ctrl with angle brackets and
it stripped them out as tags.
I meant C-p and C-n.

Nope. p and n are used extensively.
They go to the previous and next line in both emacs
and in normal mode in vi, they go forward and
backward in the history in emacs editing mode of the
shell, and, most importantly, they perform string
completion in insert mode (similar to in bash
and zsh) in vim for matching strings before or after
the current cursor position.

ctrl-P

easy to press and AFAIK unassigned anywhere.

Comment on Using OpenBSD’s OpenSMTPd for Email by LIAR

LIAR — Fri, 29 Jan 2010 09:03:08 +0000

Olá,

Thanks for the post, it helped me understanding the basics of OpenSMTPd works (even if the man pages already are very explicit).

I’ve just a little question about you sentence:
“My ISP (sonic.net) doesn’t let me use port 25, so I have to relay to their SMTP server to send mail”

In my case, it is exactly the converse: I can’t use anything else than port 25. It seems that OpenSMTPd cannot be configured to use no crypto. Am I right?

C-z is a terrible choice. Apparently you never use Berkeley
job control. I use C-z *all the time* to suspend my current
process, do something else, and then “fg” to resume. The
problem is that most of the control keys are used by one
application or another. I have been using screen on BSD and
am about to try tmux. C-a has been a minor inconvenience,
because of it being the emacs beginning of line command,
although I am primarily a vim user. C-b is the emacs
command to move the cursor back one character and the vi
command to go scroll back a page. Although, there are
alternatives, such as the arrow keys for those functions, so
C-b probably would be less of an inconvenience for me than
C-a has been.

Perhaps an ALT key, such as M-s (s for screen controls),
M-a, or M-b would be a good choice.
