I'm working through some problems in a beginners programming book. The author mentions a formula for calculating the number of ways of picking out n things from a collection of m of them:
Code:
/ m m!
| | = -----------
n / n! (m-n)!
But he does not give a name for the formula. Does anyone happen to know what it is called? I need to do some related research.

I'm simply trying to remove old kernels and second rename things that are on the list. It used to take me 10 seconds with grub1, but having some difficultly with grub2. So far I went into /boot/ and removed the old kernels and then did a sudo update-grub2 and it seemed to remove all the old kernels from the list. Is this the best way or doing it or any issues on doing it this way? Second I just want to rename what boots up like Ubuntu 2.6.32-22-generic to something else. I keep read not to modify the grub.cfg, but not sure what to do? I poked around the files in /etc/grub.d/, but not sure what to do?
View 2 Replies View RelatedI have a fresh Debian install, since this install was on a desktop, I had an internet connection and didn't notice (it was late, I was half asleep) I opted to download a whole load of packages I didn't really need. I thought all was doomed until I remembered that I have done another Debian install but a week ago on a laptop, which has a nice clean install without all the bloat.
So I ran dpkg --get-selections > selections
and had it sent to my new desktop installation.
Now if I run dpkg --set-selections < selections followed by dselect-upgrade nothing happens. I assume this is because the smaller list contains all the packages 'to be installed' which already are, and all the missing packages are not being purged. Do I need to explicitly add all the packages I want to purge to the 'selection' list or is there a better way of doing it?

There are some updates in the Update Manager list which I do not install. Among them, some drivers for HP Printers (I don't know why this cropped up; I don't even use printers on my laptop), and gcj updates (I use gcc/g++ but not gcj). I unchecked them the first time I saw them on my UM list. However, for every subsequent batch of new updates, UM retains these updates and I need to uncheck them every time. How can I remove them totally from my UM list?

I know a bunch of commands and I am comfortable using the terminal, I even set a powerpc server but I can't figure out how to remove epiphany on this new computer I'm setting up. I didn't install anything with tasksel. I installed gnome and xorg afterwards... I load it up and 'startx' just fine. then I check around for the programs that were installed. I lik'em gimp, lot's of utilities. gedit. anyway I find epiphany, which I have already established that I dislike, I immediately go to the root terminal (another nice program that comes with gnome) and type apt-get remove epiphany-browser-data the output says it will be deleting gnome... however I have researched and found these are simpy meta packages that don't really matter.... however under the section that states all the packages that will be removed by autoremove there is a huge list... I doubt these packages are safe to remove. how to remove epiphany without removing a huge amount of probably needed software
View 14 Replies View Relatedwhat i did was, remove evolution mail from synaptic, what i wanted to do was just remove the indicator applet from the task bar. i read a bunch of bad stuff about removing evolution from synaptic vs just removing the applet.
im worried. did i break anything or put my security at risk. after, i used a command (older) (sudo apt-get install ubuntu-desktop)to install ubuntu desktop. because i thought that it would fix evolution. then i went to synaptic and installed a package called evolution. i rechecked evolution in applications menu. however, i notice that i have both a checkable evolution and two evolution icons. nothing 'seems' broken. im not sure if it ever was. and evolution calender pops up as normal, as does the the installed plain evolution. they both seems to be an exact copy of the other.
all i really wanted to do was remove the indicator applet. did i make a serious mistake. since ive had ubuntu, ive reformatted a lot because i was worried i made a mistake of some kind. however now im into the more "make a mistake and fix it stage' as im pretty happy with my current desktop and have worked hard to customize it. the command, sudo apt-get remove indicator-messages removed the mail icon. i still am worried that i broke something, or put my security at risk. also, now i have two mail icons. evolution mail and calendar, and another just called evolution.
These should be my last pleas for help with regard to Fedora 13. I've been unable to turn off the notifications that appear in the top right corner, despite a decent amount of searching on google.

View 5 Replies View RelatedI'm using libxml2 to handle/manipulate some XML files. In order to check the consistency of a XML file, I have a DTD and I'm using the xmlValidateDtd method to compute the check.
However, when an error occures during the check (for example an attribute is missing in a XML tag), then libxml2 writes the error on the stdout/stderr. For exemple:
Code:
/home/XML/FreeFour.xml:18: element CA: validity error : Element CA does not carry attribute maxlength
The method return the right result (true or false depending on the check result), but occurring errors are written on the stdout/stderr, and I actually don't want that.
I'm still a but confused about the standard way of removing it for left-associative operators: [URL] Especially about how to construct an AST from it by executing a peice of code for every nonterminal matched. And I'm still not totally convinced that it will be left-associative, I just barely understand it. Also, how would you remove left-recursion for something like this:
Code:
expr ::= expr "(" param_list ")"

I need to create a program where the user creates an account and he/she is entitled to add interests and creating friendships with other users.The main algorithm depends on an object which is the user and its attributes are adding interests, friends, so on.Users are stored in a linked list while their interests are stored in another list.What I want to do is every time a new user is created dynamically create a new list during execution for personal info. storage. Is that possible?

Is there something like GtkRecentManager that will give you a list of recently-used or most-used applications instead of files, or will GtkRecentManager give you apps too?
View 1 Replies View RelatedI have a C header file which have arrays of predefined(known) structure type. But i dont have names of arrays and their size. when i include that file and compile my application, i want to know the names and sizesof those arrays.
purpose of application is to get the content of those arrays and to explain it in descriptive words instead of hex numbers.ofcourse this can be done by file pointers and reading also with out header file inclusion, but as i am working in C, once compiled, those variables are in my address space in i include header file.
I have a file witch I need to list 10 line by 10 lines with something like press enter to go on in between.
