  • Emacs, Linux and international keyboard layouts

    - by sabof
    Is there an easy way to use emacs key-bindings when you are using a not-English (Russian) keyboard layout? Whenever an international layout is on, all keystrokes are interpreted literally, M-? instead of M-a. As a result I can't use commands. It would also be nice if Linux could interpret non-prefixed and shift-prefixed keys according according to an international layout, while keeping the rest English.

  • Can splitting .MDB files into segments help with stability?

    - by Craig Johnston
    Is this a realistic solution to the problems associated with larger .mdb files: split the large .mdb file into smaller .mdb files have one 'central' .mdb containing links to the tables in the smaller .mdb files How easy would it be to make this change to an .mdb backed VB application? Could the changes to the database be done so that there are no changes required to the front-end application?

  • Entity binding WPF

    - by morphsd
    I'm doing some auction sale app and I'm new to Entity Framework. I used quickest way to create and bind Wpf control and entity(wizard and drag and drop) so VS2010 generated a lot of code for me. Now I have a problem... WPF control isn't syched to my entity. I read some articles and I understood that I have to use IObservable. Is there an easy way to do that without writing that generated code manually?

  • which of these modes : cbc,cfb,ctr,ecb,ncfb,nofb,ofb,stream are secure and which are absolute no-no

    - by user393087
    By security I mean that encoded string is indistinguishable from random noise and is different on every encryption of the same text so it is impossible to make a guess on encryption algorithm used or do any dictionary attack on the encoded text. Second: output string length does not correspond to the input string length in easy way, so it is not possible of make guessing on that account. Third: it is possible to verify that the provided password is incorrect so the decoding function could return false instead of supposedly decoded random string.

  • Setting up httpd.conf / mod_rewrite to auto-load codeigniter?

    - by Walker
    I'm sorry to ask this here, as I'm sure the solution is fairly easy but for the life of my I can't setup httpd.conf on my apache server to automatically load the code_igniter files. Instead I'm having to go into the folder itself localhost/trunk/etc/etc until I get index.php - which messes with some of the relative paths (our backend coder is gone for the week so I can't ask him, but he has already setup the rewrite rules on our development server).

  • Is MobiForms for Android worth investigating ?

    - by Alan B
    I'm working my way through the NotePad tutorial, and that's all fine - I'm not a Java programmer but it's close enough to C# (or vice versa) to make it easy to pick up. I'm surprised that there aren't any RAD tools for Android apart from Mobiforms. Is there anyone out there with experience of Mobiforms ?

    - by Holger
    Consider the following directory structure: ./source/com/mypackage/../A.java ./extensions/extension1/source/com/mypackage/../T.java ./extensions/extension2/source/com/mypackage/../U.java ... ./extensions/extensionN/source/com/mypackage/../Z.java I want to produce a source jar with the following contents: com/mypackage/../A.java com/mypackage/../T.java com/mypackage/../U.java ... com/mypackage/../Z.java I know I could use a fileset for each source directory. But is there an easy solution using ANT without having to refer to all extensions explicitly?

Any of the built-in functions like MD5 and mcrypt each make strings that are too long for my purposes. Is there an easy way to create a string like this? Thanks.

  • fire an intent from the onCreate method in android

    - by Sephy
    Maybe my question might seem a bit weird, but I have an activity in which, in one case , I have to move to another activity before it finishes loading the screen. My condition is in the onCreate method, which means when I encounter it, i get a "startActivity called from outside an activity context" error and the app just crashes... But then, is there an easy way like a flag for the intent to make it work without having the activity context resolved? thanks for any answer

  • Comparing floats in their bit representations

    - by sczizzo
    Say I want a function that takes two floats (x and y), and I want to compare them using not their float representation but rather their bitwise representation as a 32-bit unsigned int. That is, a number like -495.5 has bit representation 0b11000011111001011100000000000000 or 0xC3E5C000 as a float, and I have an unsigned int with the same bit representation (corresponding to a decimal value 3286614016, which I don't care about). Is there any easy way for me to perform an operation like <= on these floats using only the information contained in their respective unsigned int counterparts?

  • How to communicate between service controller and a service/daemon?

    - by Sorin Sbarnea
    It is easy to display the status of a Windows service or to control it (start/stop) from a GUI application but the question if how about receiving/sending notifications from the service? Like: service telling to the user monitoring it that it needs attention. Please consider that you can have several controllers started at any time in a multi-user environment. Do you know an example(open source) for this kind of communication? Extra points for a platform independent solution :)

  • How can I get node coordinates from a graph, using Perl?

    - by jonny
    Ok, I have a flowchart definition (basically, array of nodes and edges for each node). Now I want to calculate coordinates for every task in the flow, preferably hierarchycal style. I need something like Graph::Easy::Layout but I have no idea how to get nodes coordinates: I render nodes myself and I only want to retrieve box coordinates/size. Any suggestions? What I need is a CPAN module available even in Debian repository.

  • How to discover web servers on a local network?

    - by Stefan Kendall
    Suppose I'm running several servers serving basic requests on my local network (say a home network, where all machines generally have an IP in the form K.K.K.x, where x is variable). Is there an easy way to discover all such servers? I would need to find each IP on the network running a particular java server application.

  • JQuery: can I submit values from inputs that aren't in a form?

    - by Alvaro
    Simple as that: I have some inputs that are rendered inside another form element, but I want to submit then individually. I tried "serializing" the div that contains them, but it didn't work. Is there an easy way to do this? My code: var form = $("#my_div"); var get_data = $(form).serialize(); /* Get #my_div inputs value */ $.get(self.url_form_rendering, get_data, function (data){ /* handle server response */ }) Serialize returns "", any ideas that don't involve redesigning the layout to avoid form nesting?

  • How to add changebar in latex?

    - by Rabarberski
    In Latex, I've created a new command 'changedtext' to mark specifics parts in my document and make it appear blue: \newcommand{\changedtext}[1]{\textcolor{blue}{#1} } Is there any easy way to alter the command to have change bars appear next to the text in the resulting PDF? If not possible, any other suggestion for a visual markup (other than change bars) that would be clear on a black & white printout would be useful as well.
