• SQL Server 2008 - Management Studio issue

  - by Phil Streiff

  This is a known, documented issue with SQL Server 2008 Management Studio, but certain DDL operations like ALTERing a column datatype from Management Studio fails. For example, in Object Explorer, navigate to a table column > right-click on column > Modify. Then, change column datatype or length, then save and this error message displays: To workaround this problem, go to Query Editor and issue the following DDL statement instead:  TABLE dbo.FTPFile ALTER COLUMN CmdLine VARCHAR (100) ; ALTER   GO   The column change is successfuly applied now.

• Changing a Sprite When Hit in GameMaker

  - by Pixels_

  I am making a simple little Galaga style game. I want the objects sprite to change whenever it is hit. For example if a laser hits an alien then the sprite takes 1 out of 4 damage to its health points (HP). However I want the sprite to change from green to yellow after 1 hit, yellow to orange after 2 hits, orange to red after 3 hits, and red to pixel explosion after all 4 HPs are lost. That way you can easily distinguish the amount of health each alien has left. How can I do this? Preferably explain it in code.

• Add folder name to beginning of filename - getting multiple renames

  - by Flibble Wibble

  I've used dbenham's excellent response to the question of how to add the folder name to the beginning of a filename in a cmd script. @echo off pushd "Folder" for /d %%D in (*) do ( for %%F in ("%%~D\*") do ( for %%P in ("%%F\..") do ( ren "%%F" "%%~nxP_%%~nxF" ) ) ) popd What I'm finding is that seemingly randomly (though it probably isn't) sometimes the script will run through several child folders and rename correctly but then it gets to a folder where it gets stuck in a loop and starts adding the folder name repeatedly to the file inside. I have 90,000 files in 300 folders to rename this weekend. Any chance you can guess the cause? PS: Is there a maximum number of files that are acceptable in each folder?

• "// ..." comments at end of code block after } - good or bad?

  - by gablin

  I've often seen such comments be used: function foo() { ... } // foo while (...) { ... } // while if (...) { ... } // if and sometimes even as far as if (condition) { ... } // if (condition) I've never understood this practice and thus never applied it. If your code is so long that you need to know what this ending } is then perhaps you should consider splitting it up into separate functions. Also, most developers tools are able to jump to the matching bracket. And finally the last is, for me, a clear violation to the DRY principle; if you change the condition you would have to remember to change the comment as well (or else it could get messy for the maintainer, or even for you). So why do people use this? Should we use it, or is it bad practice?

• /var/tmp and file lifetime

  - by clorz

  Hi everyone I've got a cronjob that runs every minute and checks existence of a certain file. If there's no such file, job silently ends. If there is a file, then another script is started. That script removes the file when done. Its execution time can take up to 20 minutes. My questions are: Are there any flaws in this scheme? Is it ok to store such file in tmp? Can I be shure that nothing will attempt to remove it?

• Is there any complications or side effects for changing final field access/visibility modifier from private to protected?

  - by Software Engeneering Learner

  I have a private final field in one class and then I want to address that field in a subclass. I want to change field access/visibility modifier from private to protected, so I don't have to call getField() method from subclass and I can instead address that field directly (which is more clear and cohessive). Will there be any side effects or complications if I change private to protected for a final field? UPDATE: from logical point of view, it's obvious that descendant should be able to directly access all predecessor fields, right? But there are certain constraints that are imposed on private final fields by JVM, like 100% initialization guarantee after construction phase(useful for concurrency) and so on. So I would like to know, by changing from private to protected, won't that or any other constraints be compromised?

• Why does printf report an error on all but three (ASCII-range) Unicode Codepoints, yet is fine with all others?

  - by fred.bear

  The 'printf' I refer to is the standard-issue "program" (not the built-in): /usr/bin/printf I was testing printf out as a viable method of convert a Unicode Codepoint Hex-literal into its Unicoder character representation, I was looking good, and seemed flawless..(btw. the built-in printf can't do this at all (I think)... I then thought to test it at the lower extreme end of the code-spectrum, and it failed with an avalanche of errors.. All in the ASCII range (= 7 bits) The strangest thing was that 3 value printed normally; they are: $ \u0024 @ \u0040 ` \u0060 I'd like to know what is going on here. The ASCII character-set is most definitely part of the Unicode Code-point sequence.... I am puzzled, and still without a good way to bash script this particular converion.. Suggestions are welcome. To be entertained by that same avalanche of errors, paste the following code into a terminal... # Here is one of the error messages # /usr/bin/printf: invalid universal character name \u0041 # ...for them all, run the following script ( for nib1 in {0..9} {A..F}; do for nib0 in {0..9} {A..F}; do [[ $nib1 < A ]] && nl="\n" || nl=" " $(type -P printf) "\u00$nib1$nib0$nl" done done echo )

• Backup Solr home

  - by user226188

  I'm new to Solr: I've successfully installed Tomcat and Solr 4.3.1 webapp, and two collections on a CentOS 6.4 machine. Now, my server is in production and I need to make backups of solr. So, I would like to know what is the best way to backup solr... For the moment I'm dooing: stop tomcat = tar of my solr home = start tomcat, but I've read that is not a good solution? Moreover, this implie to stop all the tomcat which have other webapps than solr. I've also heard that there is a script named "backup" in solr home bin's folder ? but my bin folder is empty :( I don't want to make an another slave server with replication, for me it's not a backup solution because my backup are supposed to be send to a bacula backup server all nights. There is no builtin solution that I can work around to make a script ? like a mysqldump for Mysql servers. Thanks for help !

• How to install php cli with pnctl alongside Zend Server

  - by fazy

  I have Zend Server CE 5.6 with PHP 5.2 running on Ubuntu 11.10. Now the need has arisen to run a command line PHP script that uses PHP's pnctl functionality. First of all, I had no PHP command line in my path, so I made a symlink from the Zend one: sudo ln -s /usr/local/zend/bin/php /usr/bin However, when I run my script, I now get this error: PHP Fatal error: Call to undefined function pcntl_fork() The Zend web control panel doesn't offer pnctl in the list of modules, so how do I get this functionality? Is it safe to use apt-get to install PHP directly, to run alongside the Zend instance? If so, how do I make sure I get version 5.2? I guess the following would pull in PHP 5.3: apt-get php5-cli I could probably muddle through but any pointers to help me avoid making a mess would be much appreciated!

• Substitute Items on Internal Sales Orders

  - by ChristineS-Oracle

  Oracle Order Management now enables you to substitute items on internal sales order lines to manage item availability.  Oracle Order Management enables you to substitute items on internal sales order lines to manage item availability. Source organizations can decide to ship a substitute item in case the original item is not available to be shipped. The application supports manual (using Related Items window) and automatic (using ATP functionality) substitutions.To substitute an item on ISO, you must ensure that the value of the Item Substitution on Internal Order system parameter is set to a value other than None. In addition, you must ensure to define substitute item relationships and automatic item substitution setup in the system. The application provides the option to not send the notifications when any change happens on the ISO related to quantity, schedule arrival date, or item. You can control these notifications using the OM: Send Notifications of Internal Order Change profile option. For additional information refer to the Oracle Order Management Release Notes for Release 12.2.4 (Doc ID 1906521.1).

• Hack/software to easily move screen mapping of a wacom tablet?

  - by Riyaah

  I would like to move/manipulate the mapping of my Wacom tablet to my screen as easily as with Inklet: http://tenonedesign.com/inklet.php Is anyone aware of any software or hack to acheive this on Mac OS X? If not I'm thinking about trying to write a script that centers the mapping on the current cursor position, and then bidning that to a button on my tablet. Combined with a script for toggling between fullscreen/part of screen-mapping that should be enough. My idea so far is to edit the .prefs file since it's plain XML, and then restart the tablet driver. But any pointers relating to this would be most welcome, since my knowledge of this kind of things is rudimentary.

• Don't run cron job if already running

  - by webnoob

  Hi All, I know this question has been asked already but I either didn't understand the answer or it didn't apply to me. I have a php script that I am calling every 1 minute using CPanel to set up the Cron Job. The nature of the script means that it could overrun for just over the minute so I need to know how to stop the next one running if the first one hasn't completed. I have a VPS running CENTOS 5.5 and have access to WHM and CPanel. I have never used Linux before (only just got the server yesterday) so I have no idea what I am doing and would appreciate some help if possible. If I need to provide more information please let me know (I don't know what info you would need at the moment). Thanks.

• PHP errors not being displayed

  - by Mike

  I'm using PHP with Apache on Ubuntu 12.10. Errors are not being displayed to the browser for some reason and I can't figure it out. I have the following in my php.ini file: error_reporting = E_ALL & ~E_DEPRECATED display_errors = On display_startup_errors = On log_errors = On I am also positive that I have edited the correct ini file by verifying it with php_ini_loaded_file(). I can also verify that the values are correctly set by doing the following in my script: echo ini_get("display_errors"); // Outputs 1 echo ini_get("display_startup_errors"); // Outputs 1 echo ini_get("log_errors"); // Outputs 1 echo ini_get("error_reporting"); // Outputs -1 I have tried what seems like every possible combination of these settings (and restarting Apache after each change) and it is just not outputting errors. I am also not using ini_set anywhere in the script. It is being set only from the ini file. Any ideas why errors aren't being displayed?

• Open Terminal Here, as Root (OS X)

  - by cwd

  There is a pretty awesome applescript called "Open Terminal Here" ( http://www.entropy.ch/software/applescript/ ) which you can add to your finder's toolbar and click when you want to launch a terminal console which is set to that directory. Sometimes I need to be root, and so I end up starting terminal, doing something like sudo -i and then I have to change back to the previous directory because the sudo command is landing me in /var/root. I'm using sudo -i because I like it to load things like aliases / the bash profile. The script is applescript, and here's the important part of how it works: ... set cmd to "cd " & quoted form of the_path & " && echo $'\\ec'" ... tell application "Terminal" activate do script with command cmd How do I get this to load as root?

• Crontab -- scheduling my backups

  - by Garfonzo

  I want to do a backup every Friday night (no, this is not the whole backup routine, just part of it). Each Friday night's backup will not be overwritten until 4 weeks later. So, essentially, I have a four revolving backups: Week1, week2, week3, and week4. Now, I need the week1 backup script to run every 4 weeks. But I also want week2's script to run every four weeks. I know that I can tell the crontab to execute something every X weeks/days/hours/whatever. However, how do I set it up so that each of these four scripts actually run on different weeks, how do I avoid all 4 scripts running on the same night, then dutifully waiting for weeks only to all run again? Thanks.

• How to avoid Remove-Item PowerShell errors "process cannot access the file"?

  - by Michael Freidgeim

  We are using TfsDeployer and PowerShell script to remove the folders ising Remove-Item before deployment of a new version. Sometimes the PS script failed with the error Remove-Item : Cannot remove item Services\bin: The process cannot access the file Services\bin' because it is being used by another proc Get-ChildItem -Path $Destination -Recurse | Remove-Item <<<< -force -recurse + CategoryInfo : WriteError: (C:\Program File..\Services\bin:DirectoryInfo) [Remove-Item], IOException FullyQualifiedErrorId : RemoveFileSystemItemIOError,Microsoft.PowerShell.Commands.RemoveItemCommand I’ve tried to follow the answer from PowerShell remove force to pipe get-childitem -recurse into remove-item. get-childitem * -include *.csv -recurse | remove-item ,but the error still happens periodically. We are using unlocker to manually kill locking application, (it’s usually w3wp), but I prefer to find automated solution. Another (not ideal) option is to-suppress-powershell-errors get-childitem -recurse -force -erroraction silentlycontinue Any suggestions are welcome.

• Verify linux user passwords

  - by zero_r

  Hi there I got a linux server that has several dozen users. I also have the cleartext password for every user (i know - bad security). I would like to know if the passwords are correct. Since the users are all ftp users and have the nologin shell, I cannot just write a script to check if login works. How can I do a local check on passwords? Script output could look like this: $ check_userpw < user_pw_list.txt user1 ok user2 ok user3 mismatch! user4 ok Thanks

• Title: Better logging for cronjob output

  - by Stefan Lasiewski

  I am looking for a better way to log cronjobs. Most cronjobs tend to spam email or the console, get ignored, or create yet another logfile. In this case, I have a Nagios NSCA script which sends data to a central Nagios sever. This send_nsca script also prints a single status line to STDOUT, indicating success or failure. 0 * * * * root /usr/local/nagios/sbin/nsca_check_disk This emails the following message to root@localhost, which is then forwarded to my team of sysadmins. Spam. forwarded nsca_check_disk: 1 data packet(s) sent to host successfully. I'm looking for a log method which: Doesn't spam the messages to email or the console Don't create yet another krufty logfile which requires cleanup months or years later. Capture the log information somewhere, so it can be viewed later if desired. Works on most unixes Fits into an existing log infrastructure. Uses common syslog conventions like 'facility' Some of these are third party scripts, and don't always do logging internally.

• How to transfer a domain from 101domain to another registrar ?

  - by Wookai

  A friend of mine bought a domain name on 101domains, and now wants to have his website hosted on my servers. I would like to have full control of the DNS records, and thus would like to change the NS records to point to my DNS server. I can't find how to do that on their control panel. I can access the listing of DNS records for the domain, but cannot change it. Thus, I would like to transfer it to another registrar, that I know allows to do all these changes. How can I do that ?

• How do I allow a (local) user to start/stop services with a scheduled task?

  - by Mulmoth

  Hi, on a Windows 2008 R2 server I have two small .cmd-scripts to start/stop a certain service. They look like this net start MyService and net stop MyService I want to execute these script via scheduled task, and I thought it would be best to create a local user for this job. The user is not member of the Administrators group. But the scripts fail with exit code 2. When I logon with this local user and try to execute these script in command line, I see a message like (maybe not exactly translated from german to english): Error code 5: Access denied It doesn't matter whether I start the command line as Administrator or not. How can this local user gain rights to do the job?

• chown select files only

  - by user114642

  I use the (excellant) unison to sync two file servers and I've just realised i've synced a number of files without using the switch in unison that maintains the file user ownership. these files now have a user of root (coz i have to run unison as root) Can I chown to a specified user BUT only change the files that now have the owner root and do so recursively in the directory in question? Sure i can but not sure of the arguments to "find files with owner 0 and change them to owner xxxx". THX for any help...

• rsnapshot stats

  - by Obscur Moirage

  I'd like to retrieve the following stats from rsnapshot files synced added files modded files deleted files Is there a feature to retrieve these in rsnapshot, or is there another product that's able to do it? EDIT: As requested, I'll try to show that I'm not just asking what I want to do without any research. I wasn't able to locate any rsnapshot feature doing this. Maybe I'm searching in a wrong direction. So, I've built a not very pretty script, called each time before rsnapshot is ran. This Perl script stores each file MD5, in order to compare backup files structures between rsnapshot updates. I'm pretty sure it's worthless to show this code here. I think that keeping an eye on what change on a server, for example, is a useful feature. So, I'm asking. @pauska Most of the time, I'm trying to search for an answer myself, which is not the case here. Thanks

• Bringing the xenbr0 interface up on XEN under Ubuntu 8.04

  - by iyl

  I installed XEN on Ubuntu 8.04 using this tutorial: http://www.howtoforge.com/ubuntu-8.04-server-install-xen-from-ubuntu-repositories but after I reboot with the XEN kernel, I don't have xenbr0 device. I see that network-bridge script runs and it creates peth0 device, but not xenbr0. I have a very basic IP setup, with a single static IP defined in /etc/network/interfaces. The only unusual thing is that my hosting (1&1) gave me a netmask 255.255.255.255, so I had to add the default gateway with this script: /sbin/route add -host 10.255.255.1 dev eth0 /sbin/route add default gw 10.255.255.1 Everything else is plain vanilla Ubuntu 8.04.

• How do I debug an upstart job?

  - by Cerales

  I have the following job in /etc/init/collector: start on runlevel [2345] stop on runlevel [!2345] expect daemon exec /usr/bin/twistd -y /path/to/my/tac/file When I start the job with sudo service collector start, it hangs. If I ctrl-c and run initctl list, I see this: collector start/killed, process 616 I can't see an instance of the twistd daemon in ps, and the HTTP server it's supposed to be providing does not exist. I even tried this without 'expect daemon' and with a simple call to a one-line bash script using a script stanza, and it still doesn't work. I think I'm doing something very wrong. What could it be?
