• Deleting ASP.NET application subdirectories causes application recycle!

  - by geekrutherford

  This may not be news to most people, but was definitely a shock to me!   In the .NET 2.x framework a "feature" was implemented where by an ASP.NET application is automatically recycled if any subdirectory is deleted. This was apparently implemented to prevent stale content from appearing on a site.   The unfortunate side effect of this "feature" is that when using the "InProc" model for session management, all session data is lost if a subdirectory is deleted.   For those who progammatically may be adding/deleting directories within their application as inherent functionality, this causes a rather large problem.   The solution? Create your folder(s) which may be programmatically deleted outside of the root folder for the application. Alernatively, utilize a file based structure vs. folders since deleting files does not result in the same issue.

• Incorporating GPL Code in my Open Source Project

  - by rutherford

  I have downloaded a currently inactive GPL project with a view to updating it and releasing the completed codebase as open source. I'm not really a fan of GPL though and would rather licence my project under BSD. What are my options? Is it just a case of keeping any existing non-touched code under the GPL and any updated stuff can be BSD (messy)? The source will essentially be the same codebase i.e. there is no logical separation between the two and they certainly can't be split into anything resembling different libraries. Are my only realistic options to either GPL the whole thing or seek the original author's permission to release everthing under BSD?

• Multi option step-by-step walkthrough? [closed]

  - by James Simpson

  I'm looking for a service ideally (but script maybe) that would allow me to create a step-by-step walkthrough, customised by options users choose in earlier steps. It is difficult to describe and if there is a better description I could Google for, please let me know! Basically, I want to start with a few options for a user to click on and then change what comes next based on that click and be able to do this through a whole walk through (explaining how to set a service up). As mentioned earlier, if it was a SAAS I could use (in the vein of desk.com) that would be perfect. Thank you and please ask questions if I've described it poorly!

• What is the default permission for /var/www?

  - by itsols

  After upgrading to 12.04, I had to reinstall the LAMP stack. Then I brought all my www project folders from a pen drive to the /var/www folder (using sudo nautilus, and dragging the files in there). Now I cannot make any changes to the files/directories within /var/www. Perhaps this changed with the backup copies I dragged in there. I'd like to know what the default permissions for the /var/www folder are. I don't want to just change the permissions and make my system abnormal and working. Rather I'd like to get it to the correct state that is meant to work.

• Laptop buttons not working on a Dell Latitude e6400

  - by Ido

  I have install Ubuntu 12.10 64 bit on my Dell Latitude E6400 laptop. I have the latest bios version for my laptop (A32) which I downloaded from the official Dell website by checking updates that matches the service tag on my laptop. I'm having serious problems with all the mouse buttons on my laptop. The right-click button doesn't work at all under any circumstance. The left click button only work when clicking on icons in the left side-bar and in the top menu (like clicking on the power icon in the top-right corner or clicking on the file menu). However none of the buttons work in any of the applications even simple one like the file browser (home folder). For example when I try to click on a folder inside nautilus it doesn't work or when I try to click on the "x" close icon to close the window it also doesn't work. Can you help me figure it out?

• How to Use the File History Feature in Windows 8 to Restore Files

  - by Taylor Gibb

  Jealous of your Mac OS X friends and their great Time Machine feature? Windows 8 has a new feature called File History that works much the same way, giving you an easy method to restore previous versions of your files. We are going to use a networked folder in for our article but you could always skip creating the network folder, and just use a USB drive. To use a USB drive you can just go to the setting for File History and turn it on, it should automatically find your USB and immediately start working.

• How to specify which keys CapsLock affects?

  - by Seattle Jörg

  Using Maverick, I am not able to get the CapsLock behaviour I want: I would like it to affect essentially the alphabetical, numerical, and punctuation keys, i.e. all the keys that print something (as opposed to, say, the error keys), but only them. To illuminate this with an example: when writing code that uses % as the symbol for a comment, I want to be able to position the cursor at the start of a range of lines I want to comment out, then hit CapsLock, then iteratively hit the 5 key (using QWERTZ, Shift+5 gives %) and the arrow down key, so that I can quickly place a % at the start of the lines. Ubuntu in default configuration takes CapsLock literally, so that it affects only alphabetic keys. Under Preferences/Keyboard/Layout/Options I can make it act as a pressed Shift, but then the action of the arrow keys is to select text. All the other options available are equivalent to one of these two in my case. Is it possible to somehow get this behaviour? This is standard in Windows.

• Getting "boot error" when trying to boot from USB

  - by Jon Ball

  I'm wanting to try out Ubuntu, so followed the instructions for how to install Ubuntu onto a USB. I downloaded the .iso file, then the pendrivelinux 3 part process to make the USB bootable. I can see what looks like a full list of files on the USB (including the wubi.exe application and the syslinux folder). When I try to restart the computer with the USB in, I get the Dell start up screen, and then a black screen with "Boot Error" in the top right hand corner. Setup options (default) are to boot from Removable Device, then Hard Disc. USB is brand new, straight out of the packet. Computer: Dell Inspiron 530S BIOS: 1.0.13 OS: Windows Vista Home Edition USB: EMTEC 8Gb, formatted to FAT32 I've tried some of the tips in other help topics (holding down CTRL key while restarting, removing all other USB devices). I tried to reformat the USB to something other than FAT32, but my only other options were NTFS or exFAT (not FAT16 which was suggested in another topic).

• How to set-up a simple subversion workflow

  - by Milen Bilyanov

  I am trying to set-up a simple SVN workflow at home. I am new to subversion (and programming) so I have been reading the official PDF documentations but still not sure about how to set-up my repository. I am working mainly with python, bash and rsl (Renderman Shading Language) So I already have a /dev structure on my disk as this: http://imageshack.us/f/708/devstructure.png/ And I have a /site structure that links to my /dev folder: http://imageshack.us/f/651/sitestructure.png/ So obviously starting to use SVN will change this approach that I already have in place. The question is when I am setting-up my SVN repository for the work I do in my /dev folder: Will I set-up a separate repository for each different programming platform? and Where exactly I should be placing my repository? Thanks.

• I'm in a group but can't create or modify files

  - by dac

  I have two user accounts. Let's say one is User1 and the other is User2. Both of these accounts are in the "root" group. I made a folder with some files in it. The owner is User1 and the group is root. The permissions are set so the group "root" can create and delete files. However, when I log in as User2, I can only access files. User2 is in the "root" group for sure, and when I right-click on the folder in Nautilus, and then PropertiesPermissions, it says there that the "root" group can create and delete files. What's going on? edit: Logged out and then back in, and, I don't know why, everything works now...

• Trial/Free & Full Version VS. Free App + In-app billing?

  - by SERPRO

  I'm just wondering what would be the best strategy to publish an application on the Android Market. If you have a free and paid version you have two codes to update (I know it will be 99% the same but still) and besides all the popular paid apps are quite easy to find for "free" in "alternative" markets. Also if you have any stored data in the trial/free version you lose it when you buy the full version.. On the other hand if you put a free application but inside you allow the user to unlock options (remove ads/more settings/etc...) you only have to worry about one code. I don't know the drawbacks of that strategy and how easy/hard is to hack that to get all the options for "free".

• SQL SERVER – Backup SQL databases to Box or SkyDrive

  - by Pinal Dave

  To ensure your SQL Server or Azure databases remain safe, you should backup your databases periodically. And it is important to store the backups in a reliable location. Microsoft SkyDrive currently offers 7GB free, Box offers 5GB free – both are reliable and it is simple to send your backups there. SQLBackupAndFTP in it’s latest version 9 added the option to backup to SkyDrive and Box ( in addition to local/network folder, NAS drive, FTP, Dropbox, Google Drive and Amazon S3). Just select the databases that you’d like to backup and select to store the backups in SkyDrive or Box. Below I will show you how to do it in details Select databases to backup First connect to your SQL Server or Azure Sql Database. Then select the databases you’d like to backup. Connect to SkyDrive or Box cloud If you have a free version of SQLBackupAndFTP Box destination is included, but SkyDrive destination will be disabled as it is available in the Standard version or above. Click “Try now” to get 30 days trial on all options On the “SkyDrive Settings” form you’ll need to authorize SQLBackupAndFTP to access your SkyDrive. Click “Authorize…” to open SkyDrive authorization page in your browser, sign in your to SkyDrive account and click at “Allow” . On the next page you will see the field with authorization code. Copy it to the clipboard. Box operation is just the same. After that return to SQLBackupAndFTP, paste the authorization code and click “OK” . After you are authorized, you can enter the path to a backup folder. SQLBackupAndFTP will create the folder if it does not exist. That’s all what has to be done to backup to SkyDrive or Box cloud.  You can now click on “Run Now” button to test this job. Conclusion Whatever is your preference for storing SQL backups, it is easy with SQLBackupAndFTP. Note that at the time of this writing they are running a very rare promotion on volume licenses: 5–9 licenses: 20% off 10–19 licenses: 35% off more than 20 licenses: 50% off Please let me know your favorite options for storing the backups.

• The layout page "~/Views/Shared/_Layout.cshtml" could not be found

  - by Rei Brazilva

  I got this error and I can't figure out what is going on. I am positive the _layout.cshtml resides in the shared folder and for the sake of trying things out, I moved to the Home folder and it then told that the Views/Home/_Layout.cshtml couldn't be found there either. So now I'm thinking the problem is in the call for this file for some reason. I'm not going to pretend I know ASP.NET MVC4, so please when you answer, explain it as you would to someone who is not familiar with the system at all. Believe it or not, this error came from tutorial #1 ha ha Here's the code to show that I did code it right: @{ ViewBag.Title = "Home Page"; Layout = "~/Views/Shared/_Layout.cshtml"; } And here is a picture of the location p.s. I did my research, Google has nothing and there is another question here but it was asked on 2008 with MVC3 which is completely different I am running ASP.NET MVC4 on Azure Thanks

• Installing software on an offline Ubuntu server

  - by Muhammad Gelbana

  Assuming that I have a server with Ubuntu server newly installed on it. I was thinking of installing the very same version on Virtual Box (Or any other virtualization software), connect it to the internet and use apt-get to only download the packages for upgrading the system and the new software such as (tomcat7, openjdk6-default-headless..etc). Then copy the downloaded packages from the archive folder to the offline server's archive folder through a USB stick. So now the virtual system won't actually be upgraded nor have any new software installed. But would running the very same apt-get commands on the offline system without the download directive -d be executed without issues ? *EDIT:*This needs to be as simple as possible because I'll have to write a guide for our client to do this on his own and so it won't be acceptable to require deep Linux knowledge to do this.

• Size doesn't matter

  - by ssoolsma

  Whenever I start a new project I *always* break up my code in different projects. Also known as n-tier solution. The scale of  the project doesn't matter, but make sure that each project is responsible for himself (or herself if you prefer). I make sure that i ....At least thought about how the project should work on the toilet or in a project team meeting.Have a solution directory and create my projects within. I like to name my project (and it's folders by the namespaces). For instance: When i'm creating a piece of (web)software called: ChuckNorris, i always include the software name in my projects. Start off with designing the DataAccess project. I name it: ChuckNorris.DataAccess which lets me easily identify the project incase the project scales alot.Build the classes which represent the database structure. Don't stop working on a class untill it's finished for now. Also, don't over-do the methods. Build stuff only when it's needed, and not think: "Hm, that would be cool to have". Cause most of the time you end up with unused code, and we don't want that.Build a unittest project and make sure you create the folder inside the project that it's testing. So, create the ChuckNorris.DataAccess.UnitTest project inside the folder of the dataaccess project. I would suggest using the nUnit testframework.Incase you though, hm i skip unittest: Don't! Just build it - it will safe you alot of time later onNow, read 5 again. Build that bloody unittest. Don't skip. (i cant emphasize this enough)Now, every class in the dataaccess project is responsible for itself. They don't rely on each other. This is where we use the BusinessLogic project for. Start creating the ChuckNorris.BusinessLogic project. (not inside the data-access project ofcourse, but withing the ChuckNorris folder.Combine stuff from data-access. This usual involves alot of copying the data-access classes and feels silly at first. (we'll get to that later on)Now you come up to a point of creating a service project. You might not always see why to use it, but see it as a way to expose your businesslogic to any application (including your own). Sometimes i use it as a so-called "Factory". Every call goes through this factory, so that's the only thing i'm exposing to any program, and make sure that those methods are the only ones that I allow you to invoke.Build any UI (website, phoneapp, forms application, silverlight, wpf or whatever) and reference it to you service project. Fall in love (cough) with this approach.It's possible that it doesn't seem to make much sense, and very incomplete. Well, that last part is correct. Next post will go in to detail of setting up your Data-Access project and use the entity framework.

• Using EUSM to manage EUS mappings in OUD

  - by Sylvain Duloutre

  EUSM is a command line tool that can be used to manage the EUS settings starting with the 11.1 release of Oracle. In the 11.1 release the tool is not yet documented in the Oracle EUS documentation, but this is planned for a coming release. The same commands used by EUSM can be performed from the Database Console GUI or from Grid Control*. For more details, search for the document ID 1085065.1 on OTN. The examples below don't include all the EUSM options, only the options that are used by EUS. EUSM is user friendly and intuitive. Typing eusm help <option> lists the parameters to be used for any of the available options. Here are the options related to connectivity with OUD : ldap_host="gnb.fr.oracle.com" - name of the OUD server. ldap_port=1389 - nonSSL (SASL) port used for OUD connections.  ldap_user_dn="cn=directory manager" - OUD administrator nameldap_user_password="welcome1" - OUD administrator password Find below common commands: To List Enterprise roles in OUD eusm listEnterpriseRoles domain_name=<Domain> realm_dn=<realm> ldap_host=<hostname> ldap_port=<port> ldap_user_dn=<oud administrator> ldap_user_password=<oud admin password> To List Mappings eusm listMappings domain_name=<Domain> realm_dn=<realm> ldap_host=<hostname> ldap_port=<port> ldap_user_dn=<oud admin> ldap_user_password=<oud admin password> To List Enterprise Role Info eusm listEnterpriseRoleInfo enterprise_role=<rdn of enterprise role> domain_name=<Domain> realm_dn=<realm> ldap_host=<hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password=<oud admin password> To Create Enterprise Role eusm createRole enterprise_role=<rdn of the enterprise role> domain_name=<Domain> realm_dn=<realm> ldap_host=<hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password=<oud admin password> To Create User-Schema Mapping eusm createMapping database_name=<SID of target database> realm_dn="<realm>" map_type=<ENTRY/SUBTREE> map_dn="<dn of enterprise user>" schema="<name of the shared schema>" ldap_host=<oud hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password="<oud admin password>" To Create Proxy Permission eusm createProxyPerm proxy_permission=<Name of the proxypermission> domain_name=<Domain> realm_dn="<realm>" ldap_host=<hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password=<oud admin password> To Grant Proxy permission to Proxy group eusm grantProxyPerm proxy_permission=<Name of the proxy permission> domain_name=<Domain> realm_dn="<realm>" ldap_host=<hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password=<password> group_dn="<dn of the enterprise group>" To Map proxy permission to proxy user in DB eusm addTargetUser proxy_permission=<Name of the proxy permission> domain_name=<Domain> realm_dn="<realm>" ldap_host=<hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password=<oud admin password> database_name=<SID of the target database> target_user=<target database user> dbuser=<Database user with DBA privileges> dbuser_password=<database user password> dbconnect_string=<database_host>:<port>:<DBSID> Enterprise role to Global role mapping eusm addGlobalRole enterprise_role=<rdn of the enterprise role> domain_name=<Domain> realm_dn="<realm>" database_name=<SID of the target database> global_role=<name of the global role defined in the target database> dbuser=<database user> dbuser_password=<database user password> dbconnect_string=<database_host>:<port>:<DBSID> ldap_host=<oid_hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password=<oud admin password>

User Request/ Session in my Controller method and do my work Use RequestContextHolde to access Session information. I am separating some calculation logic from Controller and want to access Session information in this new layer and for that i have 2 options Pass session or Request object to other method in other layer and perform my work. use RequestContextHolder.currentRequestAttributes() to access request/ session and perform my work. I am not sure which is right way to go? with second approach, i can see that method calling will be more clean and i need not to pass request/ session each time.

• How to get faster iteration times in android development

  - by Sebastian Bugiu

  I'm creating a game on the android platform that uses the resources/raw folder for assets and scripts. The problem is that every time I change something I have to rebuild the application to test the new variant. Of course this is bad for iteration times. Any ideas about what I can do to avoid rebuilding every time I change something? This *.apk format is getting on my nerves now that I have to recreate it every time I change a word in my scripts. Or at least how to make eclipse auto-rebuild every time I change something in my resources folder so that I don't have to go to Project-Build every time?
