  • Cross platform /dev/null in Python

    - by Tristan
    I'm using the following code to hide stderr on Linux/OSX for a Python library I do not control that writes to stderr by default: f = open("/dev/null","w") zookeeper.set_log_stream(f) Is there an easy cross platform alternative to /dev/null? Ideally it would not consume memory since this is a long running process.

  • Is it possible to turn a View-Based App into a navigation-Based App?

    - by chubsta
    I am close to finishing my first application (a UITableView style one) on the iphone but have realised it will look much better, and stand a far better chance of getting through the approval process, if it is presented as a navigation-based app rather than a view-based one - in hindsight my initial choice is not really suitable... Is it possible for me to somehow change easily the application into a new type, or would i be better starting again from scratch with all the hassle that would entail... thanks for any advice on how it may be done, karl

  • what is "removing backup files" installation step

    - by mfeingold
    In many windows installers the last step is called "removing backup files". I understand that to provide transactional integrity of the install process some "backup files" could've been created and have to be cleaned up. What I do not understand is why on many occasions this step takes considerably longer than the rest of the installation. Any idea why?

  • Shell complains 'cannot execute binary file'

    - by Negai
    Hi everyone, I've playing around with linux and noticed that for some mysterious reason commands like '/bin/sh ' just will not work. Each time I'm trying to start a process it yields 'cannot execute binary file' error message. m@sanctuary:~$ sh sed /bin/sed: /bin/sed: cannot execute binary file When I first launch sh and try to execute sed, it succeeds. I'm starting to loose my wits. It would be just great, if somebody could help me. Thank you.

  • Correct term for PSD to HTML to CMS

    - by John Magnolia
    Hi, I have heard a lot of different terms to describe the process of turning a website design into a editable CMS. Currently I take the design and "slice" this up into HTML and CSS then I "plug" this into a CMS. I would class this as frontend development depending on the level of customisation required for the CMS. The reason I ask is I am currently writing up my CV and have become stuck on the correct term for this. Kind Regards

  • Counting context switches per thread

    - by Sarmun
    Is there a way to see how many context switches each thread generates? (both in and out if possible) Either in X/s, or to let it run and give aggregated data after some time. (either on linux or on windows) I have found only tools that give aggregated context-switching number for whole os or per process. My program makes many context switches (50k/s), probably a lot not necessary, but I am not sure where to start optimizing, where do most of those happen.

  • Is there a way to inspect the current rpath on Linux?

    - by Justicle
    I'm aware that it is possible to use 'readelf -d | grep RPATH' to inspect a given binary from the shell, but is it possible to do this within a process? Something like (my completely made up system call): /* get a copy of current rpath into buffer */ sys_get_current_rpath(&buffer); I'm trying to diagnose some suspect SO linking issues in our codebase, and would like to inspect the RPATH this way if possible (I'd rather not have to spawn an external script).

  • Entity Framework 4 omits some associations during model generation

    - by kzen
    After creating an EF4 model from a SQL Server database I noticed that all the relationships of my Users table were not imported into the model as associations. All the other relationships were imported fine. My Users table has a PK userId which is a char(7) field and it is integrated into several other tables in the database as an FK but for some reason EF4 does not import these relationships as associations during the model generation process... Does anyone have any ideas why this would be happening?

  • Serialize() not using .XmlSerializers.dll produced with Sgen

    - by MDE
    I have a sgen step in my .NET 3.5 library, producing a correct XYZ.XmlSerializers.dll in the output directory. Still having poor serialization performance, I discovered that .NET was still invoking a csc at runtime. Using process monitor, I saw that .NET was searching for a dll named "XYZ.XmlSerializers.-1378521009.dll". Why is there a '-1378521009' in the filename ? How to tell .NET to use the 'normal' DLL produced by sgen ?

    I am quite new to ant and have been looking at the tasks. I am trying to generate an xml file. Do I need to call an external process or does ant have some way to do this? It could be as simple as sending a string to a txt file and saving it as a .xml. Is it possible?

  • How to connect two files and use the radio button?

    - by Stupefy101
    I have here a set of form from the index.php to upload a zip file, select an option then perform a converter process. <form action="" method="post" accept-charset="utf-8"> <p class="buttons"><input type="file" value="" name="zip_file"/></p> </form> <form action="index.php" method="post" accept-charset="utf-8" name="form1"> <h3><input type="radio" name="option" value="option1"/> Option1 </h3> <h3><input type="radio" name="option" value="option2"/> Option2 </h3> <h3><input type="radio" name="option" value="option3"/> Option3 </h3> <p class="buttons"><input type="submit" value="Convert"/></p> </form> In the other hand, this is my code for the upload.php that will extract the Zip file. <?php if($_FILES["zip_file"]["name"]) { $filename = $_FILES["zip_file"]["name"]; $source = $_FILES["zip_file"]["tmp_name"]; $type = $_FILES["zip_file"]["type"]; $name = explode(".", $filename); $accepted_types = array('application/zip', 'application/x-zip-compressed', 'multipart/x-zip', 'application/x-compressed'); foreach($accepted_types as $mime_type) { if($mime_type == $type) { $okay = true; break; } } $continue = strtolower($name[1]) == 'zip' ? true : false; if(!$continue) { $message = "The file you are trying to upload is not a .zip file.
