  • Slow tab completion for paths in`make' arguments

    - by ajwood
    When I'm specifying an argument for make like PREFIX_PATH=/some/path/to/prefix/ I sometimes experience very slow completion for my directories (a few seconds). It's annoying when I've got several variables to specify. To get around the problem I've been typing out the variables first to get regular completion speed, then hitting home' to insertmake` that the start of my command line. What is happening and how can I fix it?

  • Interpolating data points in Excel

    - by Niels Basjes
    Hi, I'm sure this is the kind of problem other have solved many times before. A group of people are going to do measurements (Home energy usage to be exact). All of them will do that at different times and in different intervals. So what I'll get from each person is a set of {date, value} pairs where there are dates missing in the set. What I need is a complete set of {date, value} pairs where for each date withing the range a value is known (either measured or calculated). I expect that a simple linear interpolation would suffice for this project. If I assume that it must be done in Excel. What is the best way to interpolate in such a dataset (so I have a value for every day) ? Thanks. NOTE: When these datasets are complete I'll determine the slope (i.e. usage per day) and from that we can start doing home-to-home comparisons. ADDITIONAL INFO After first few suggestions: I do not want to manually figure out where the holes are in my measurement set (too many incomplete measurement sets!!). I'm looking for something (existing) automatic to do that for me. So if my input is {2009-06-01, 10} {2009-06-03, 20} {2009-06-06, 110} Then I expect to automatically get {2009-06-01, 10} {2009-06-02, 15} {2009-06-03, 20} {2009-06-04, 50} {2009-06-05, 80} {2009-06-06, 110} Yes, I can write software that does this. I am just hoping that someone already has a "ready to run" software (Excel) feature for this (rather generic) problem.

  • Is there a good J2ME IDE?

    - by William
    Is there a good J2ME IDE? I mean something lightweight, and portable. Something that can run what you program on it. My favorite Java IDE is JCreator Lite. Is there something like that for J2ME? Also, which would you say is the best J2ME IDE?

  • JQuery Tabbed Nav Menu and PHP Forms Question?

    - by SlAcKeR
    I'm using a JQuery Tabbed Menu which holds different types of forms and when I select a different form located under a different tab and submit the form the tab will jump to the default tab instead of the current tab the form is located in. I was wondering how would I go about fixing this so that when the form is submitted the current tab is still selected, is it the JQuery or PHP problem? Here is the JQuery. $(document).ready(function() { //When page loads... $(".form-content").hide(); //Hide all content var firstMenu = $("#home-menu ul li:first"); firstMenu.show(); firstMenu.find("a").addClass("selected-link"); //Activate first tab $(".form-content:first").show(); //Show first tab content //On Click Event $("#home-menu ul li").click(function() { $("#home-menu ul li a").removeClass("selected-link"); //Remove any "selected-link" class $(this).find("a").addClass("selected-link"); //Add "selected-link" class to selected tab $(".form-content").hide(); //Hide all tab content var activeTab = $(this).find("a").attr("href"); //Find the href attribute value to identify the selected-link tab + content $(activeTab).fadeIn(); //Fade in the selected-link ID content return false; }); });

  • Python to see if a file falls into a date range

    - by tod
    I have a script that I want to have an if statement check if a file falls between several specified date periods as it searches directories. I have been able to get the time in %Y-%m-%d format for the file, but I can't seem to be able to specify a date range for python to go through. Any ideas/help? Here's what I have so far for name in files: f = os.path.join(root, name) dt = os.path.getmtime(f) nwdt = time.gmtime(dt) ndt = time.strftime('%Y-%m-%d', nwdt)

  • building a gl3 app under cygwin

    - by user445264
    i've got a small opengl 3.2 app that i've been developing on linux using the standard gnu tools (gmake/gcc). the code seems pretty portable--i had no problems running it on osx until i started using gl3 features that the mac mini gl drivers don't seem to support. i've got a bootcamp partition with windows xp on the same mini, and i'd like to run my app there if possible. the windows drivers definitely support gl 3.2, but i'm having trouble linking. this seems like a really common issue, but i haven't found any answers online that address using opengl 1.2 under cygwin. i'm using glew-1.5.5 and linking like so: g++ -o glToy *.o -L/cygdrive/c/Program\ Files/glew-1.5.5/lib -lglew32 -lglut32 -lglu32 -lopengl32 but i get a whole lot of this sort of output: Program.o:/home/Jacob/glToy/Program.cpp:134: undefined reference to `__imp____glewUseProgram' Program.o:/home/Jacob/glToy/Program.cpp:235: undefined reference to `__imp____glewActiveTexture' Program.o:/home/Jacob/glToy/Program.cpp:73: undefined reference to `__imp____glewGetShaderiv' ... any ideas what i'm doing wrong? or perhaps this isn't a workable setup? other ideas for getting this going on the mac mini (2009 version)? thanks!

  • Backup linux to ftp server

    - by Alakdae
    What do you use for backups to ftp server? I've tried the setup with Amanda and virtual tapes on the ftp server mounted with Curlftpfs and I'm not satisfied with it. I just don't feel confident about Amanda. Also I cannot use anything that uses rsync on the ftp mounted filesystem because it only creates the directories and doesn't create files as it cannot execute "mkstemp". I've been thinking about Bacula but I can't find any good HOWTO for it.

  • Removing orphan vmware images

    - by Brad Bruce
    I am trying to remove some VMWare images that were created by a machine that is no longer available. We do not plan to use VMWare and would like to clear up the space. I get a message Cannot delete [filename]... for all of the files in these directories. Can anyone tell me how to delete them (short of reformatting)? Thanks

  • Installing a wiki on Snow Leopard

    - by JPCF
    Hi... I want to install twiki on my mac and serve it from ~/Sites/. Because the wiki has code to be run, I have to modify the user and group of wiki's files and directories, but I'm not sure about the following: 1) It is secure to change the user and group of the directory to the web server's group? If not, what can I do having into account that I'll not put 777 permissions on those files? 2) How are named apache and web user groups? Thanks

  • Windows XP: How to delete files that cannot be deleted?

    - by glenneroo
    I have a backup copy of my previous Documents and Settings folder which only contains my original user and within that, 2 directories (Favorites and Local Settings) which are visible in cmd shell but when I try to delete them, Windows gives me this error: If I try to delete the Documents and Settings folder, I receive this warning: I tried doing this in a cmd shell: attrib *.* -r -a -s -h /s But it did not help, nor did it return any errors/warnings. Unlocker 1.8.5 returns: No Locking handle found. Any ideas?

  • Understanding exim configuration files

    - by bobobobo
    So, I want to understand what's going on with this Exim configuration directory. In /etc/exim4, there's: * exim4.conf.template * update-exim4.conf.conf * conf.d The conf.d has a mess of directories and files, and inside each are a bunch of if statements which I find really different. For example: maildir_home: debug_print = "T: maildir_home for $local_part@$domain" driver = appendfile .ifdef MAILDIR_HOME_MAILDIR_LOCATION directory = MAILDIR_HOME_MAILDIR_LOCATION .else directory = $home/Maildir .endif .ifdef MAILDIR_HOME_CREATE_DIRECTORY create_directory .endif .ifdef MAILDIR_HOME_CREATE_FILE My question is, where do the CAPS VARIABLES get defined how can I change them why are there so many if statements in these configuration files?

  • jquery animated buttons that just wont behave

    - by TJ Sherrill
    Ok I have a inline list of buttons. <ul id="nav"> <li class="home"><a href="#">Menu Item</a></li> <li class="contact"><a href="#">Menu Item</a></li> <li class="about"><a href="#">Menu Item</a></li> </ul> .home{ position:absolute; bottom:0; background-image:url(../img/menu/single_line.png); background-repeat:no-repeat; height:34px; width:134px; } .home_hover{ position:absolute; bottom:0; background-image:url(../img/menu/single_line_over.png); background-repeat:no-repeat; height:70px; width:134px; } $(document).ready(function(){ $("#nav .home").mouseover(function(){ $(this).toggleClass("home_hover").slideToggle("slow"); return false; }).mouseout(function(){ $(this).toggleClass("home_hover").slideToggle("slow"); return false; }); }); Each menu item has a background image, and then when its hovered the background image is replaced by a taller image. Ultimately I am trying to build a simple menu where on mouseover the menu item appears to slide up. But in reality Jquery can animate the toggleClass with slideToggle. The problem is that this current code doesn't behave right. It jumps up and down, because the text is moving. I am pretty new to Jquery so any help is greatly appreciated. I also loaded this up at http://gasworks.ravennainteractive.com/result/ thanks

  • RTTI and Portability in C++

    - by Joshua
    If a compiler doesn't "support" RTTI, does that mean that the compiler can not handle class hierarchies that have virtual functions in them? Or have I been misunderstanding the literature about how RTTI isn't portable, and the issues lie elsewhere?

  • Programming Environment for a Motorola 68000 in Linux

    - by Nick Presta
    Greetings all, I am taking a Structure and Application of Microcomputers course this semester and we're programming with the Motorola 68000 series CPU/board. The course syllabus suggests running something like Easy68K or Teesside Motorola 68000 Assembler/Emulator at home to test our programs. I told my prof I run x64 Linux and asked what sort of environment I would need to complete my coursework. He said that the easiest environment to use is a Windows XP 32bit VM with one of the two suggested applications installed, however, he doesn't really care what I use as long as I can test what I write at home. So I'm asking if there exists some sort of emulator or environment for Linux so I can test my code, and what sort of caveats I will run into by writing and testing my code in Linux. Also, I plan to do my editing in Vim, which probably isn't a problem, but I would like any insight into editors for 68000 assembly, if you have any. Thanks! EDIT: Just to clarify - I don't want to install Linux on the board at all - I want to program on my home machine, test the code locally, and then bring it onto the board for grading/running.

  • Why is overloading operator&() prohibited for classes stored in STL containers?

    - by sharptooth
    Suddenly in this article ("problem 2") I see a statement that C++ Standard prohibits using STL containers for storing elemants of class if that class has an overloaded operator&(). Having overloaded operator&() can indeed be problematic, but looks like a default "address-of" operator can be used easily through a set of dirty-looking casts that are used in boost::addressof() and are believed to be portable and standard-compilant. Why is having an overloaded operator&() prohibited for classes stored in STL containers while the boost::addressof() workaround exists?

  • Resource mapping in a Ruby on Rails URL (RESTful API)

    - by randombits
    I'm having a bit of difficulty coming up with the right answer to this, so I will solicit my problem here. I'm working on a RESTFul API. Naturally, I have multiple resources, some of which consist of parent to child relationships, some of which are stand alone resources. Where I'm having a bit of difficulty is figuring out how to make things easier for the folks who will be building clients against my API. The situation is this. Hypothetically I have a 'Street' resource. Each street has multiple homes. So Street :has_many to Homes and Homes :belongs_to Street. If a user wants to request an HTTP GET on a specific home resource, the following should work: http://mymap/streets/5/homes/10 That allows a user to get information for a home with the id 10. Straight forward. My question is, am I breaking the rules of the book by giving the user access to: http://mymap/homes/10 Technically that home resource exists on its own without the street. It makes sense that it exists as its own entity without an encapsulating street, even though business logic says otherwise. What's the best way to handle this?

  • C++ and,or,not,xor keywords [closed]

    - by uray
    Possible Duplicate: The written versions of the logical operators. I notice that C++ define keyword and, or, not, xor, and_eq, or_eq, not_eq and xor_eq as an alternative to &&, ||, !, ^, &=, |=, != and |=. and they're rarely used! What's wrong? Are they not portable?

  • Moving from Windows to Ubuntu.

    - by djzmo
    Hello there, I used to program in Windows with Microsoft Visual C++ and I need to make some of my portable programs (written in portable C++) to be cross-platform, or at least I can release a working version of my program for both Linux and Windows. I am total newcomer in Linux application development (and rarely use the OS itself). So, today, I installed Ubuntu 10.04 LTS (through Wubi) and equipped Code::Blocks with the g++ compiler as my main weapon. Then I compiled my very first Hello World linux program, and I confused about the output program. I can run my program through the "Build and Run" menu option in Code::Blocks, but when I tried to launch the compiled application externally through a File Browser (in /media/MyNTFSPartition/MyProject/bin/Release; yes, I saved it in my NTFS partition), the program didn't show up. Why? I ran out of idea. I need to change my Windows and Microsoft Visual Studio mindset to Linux and Code::Blocks mindset. So I came up with these questions: How can I execute my compiled linux programs externally (outside IDE)? In Windows, I simply run the generated executable (.exe) file How can I distribute my linux application? In Windows, I simply distribute the executable files with the corresponding DLL files (if any) What is the equivalent of LIBs (static library) and DLLs (dynamic library) in linux and how to use them? In Windows/Visual Studio, I simply add the required libraries to the Additional Dependencies in the Project Settings, and my program will automatically link with the required static library(-ies)/DLLs. Is it possible to use the "binary form" of a C++ library (if provided) so that I wouldn't need to recompile the entire library source code? In Windows, yes. Sometimes precompiled *.lib files are provided. If I want to create a wxWidgets application in Linux, which package should I pick for Ubuntu? wxGTK or wxX11? Can I run wxGTK program under X11? In Windows, I use wxMSW, Of course. If question no. 4 is answered possible, are precompiled wxX11/wxGTK library exists out there? Haven't tried deep google search. In Windows, there is a project called "wxPack" (http://wxpack.sourceforge.net/) that saves a lot of my time. Sorry for asking many questions, but I am really confused on these linux development fundamentals. Any kind of help would be appreciated =) Thanks.

  • wordpress php > div issue

    - by Philip Bateman
    Thanks in advance for you help Ive been doing this as a lovejob for friends and now im getting quotes of several hundred dollars for minor homepage variation and I'm not sure if its valid. I'm not a programmer myself, just trying hard :) Via the CafePress press75 theme, I'm trying to go from 1 / 2 / 3 column home layout, to 1-2 merged and 3, push the 2nd column data to the right and have the 1st column span as a 16:9 gallery (nextgengallery plugin installed). Is this really a complex thing from a coding perspective? The current guy talking to me is saying its going to cost $700 or 800 AUD to alter, which is rough when the template cost $85.. From this http://shocolate.com.au.previewdns.com/wp-content/uploads/2010/05/shocolatecurrent.jpg to this 'url+Shocolatelooklikethis.jpg' I was able to get the sidebar removed by taking out ‘‘ near the bottom of home.css.. Just can’t get the middle data to flow over it? This would be ideal as a result, as the system puts the latest selected blog post on the homepage, so if we can get rid of the sidebar div and have the text appear where it was, that would be ideal. Removing the sidebar from the bottom of home.php and setting the thumbnail width to say 450 gives me the result im after EXCEPT the text doesn’t fill where the sidebar is, it wraps underneath. Reference 'shocolate.com.au.previewdns.com' for current site Thank you!!! Phil (Melbourne)
