Programming :: Python Equivalent For "array_unique" Function In Php?
May 11, 2010Is there a python equivalent for the "array_unique" function in php?
I have to run a query on a very large table (1.5 million records, with no index!) and php can't beat the max execution time. So I am converting my php script to python, which I have never used before.
my php script basically does this:
gets results from database
gets the number of unique values in column "X"
counts how many times each unique value in column "X" occurs
echos the results
My php script was originally running on a smaller version of the table, I would have started in python if I would have known the "real" table was so large, python is the only language I have access to in my current environment (besides php).
Fedora Installation :: Change The Equivalent Of The Old Inittab Function?
Jul 8, 2010In Fedora 8
File: /etc/inittab contained
S0:2345:respawn:/usr/sbin/faxgetty ttyS0
S1:2345:respawn:/sbin/vgetty ttyS1
In Fedora 13
Created folder: /etc/event.d
Created files: /etc/event.d/ttyS0

Neither faxgetty or vgetty start on reboot or changing runlevel. How do you implement the equivalent of the old inittab function?
Debian Multimedia :: Squeeze: Use Hibernate Function On Fluxbox?
Jan 28, 2011I upgraded from Lenny to Squeeze.
I use Fluxbox as the window manager in X Window. I installed hibernate packages and gnome power management. I set the idle time at 30 minutes using the gnome power management program. It doesn't suspend at all. The monitor only shuts off during idle.
So, I logged in as root, started X. Without .xinitrc gnome desktop manager launched. As I clicked shutdown, it showed a dialog box asking hibernate / suspend / restart / etc. And then, I chose the [hibernate], the system shut down and came back to previous status when system restarted.
Which gnome program does control hibernate / suspend?
Is there anyway that I can control hibernate / suspend in command? I just need to make a little script and assign it to a launch key so that I can suspend the system when it's on idle.
General :: Mint And Hibernate Function - Will Not Turn On Even After A Hard Shut Down
Jan 5, 2011I have been using Linux Mint with great success for about 5 months. The other day when I went to turn off my computer instead of selecting shut down, I accidentally clicked on "Hibernate". Now my computer will not turn on, even after a hard shut down. Nothing comes up, not even the BIOs screen. It did this once before and my Linux-guru ex was able to fix it, but I will be dammed if I remember what he did.

Programming :: Passing Data From Interrupt Handler Function To Tasklet Function?
May 18, 2010I am doing some Linux kernel programming for my research project. I need to record the timestamp (by using cpuid and rdtsc) when an interrupt handler (top half) is first invoked. Due to the time critical nature of the problem itself, I have to do the timestamping inside the interrupt handler itself (the first operation when the handler is called). However, I understand that tasks that are not so time critical should be deferred to a tasklet function (bottom half) for processing because other interrupts are disabled in a (top-half) interrupt handler. I am currently out of idea on how I can pass the timestamp information that I have obtained in the interrupt handler to the corresponding tasklet function.

Programming :: Python Equivalent Of C Ternary Operator?
Jun 12, 2010I've been reading and googling, etc. I've seen some things, but not a definite explanation of this. What is the appropriate way to mimic a C ternary operator using Python? Isn't there an exact proper way to do it? Any difference for using lambda functions? I'm sorry, but I've been searching and it's ambiguous to me how this should be handled. I would appreciate a person's help on this. I came up with this link, but I'm wondering if I'm missing something.[URL]...
So, is that it? In Dive Into Python, it's using the and-or trick. Well, if the above post is the full explanation,
