• Stop WSUS from rebooting a server

  - by sixlettervariables

  Our IT department is rolling out a set of patches via WSUS this weekend and will reboot all of our Win2k3 servers on Sunday. Due to production work which must continue uninhibited, we cannot allow this reboot to occur. The exact line we have been given is: The command to download the patches and reboot on Sunday has been sent by WSUS already and cannot be taken back. The servers will reboot on Sunday automatically. How can we go about stopping this from happening? It set some flag saying it should reboot, so what flag do we unset? One strategy proposed was to roll back the system clock, however, this will likely cause some processes to fail.

• htaccess filesMatch exclusion

  - by Hikari

  I have the following directive in my htaccess <filesMatch "\.(gif|jpe?g|png|js|css|swf|php|ico|txt|pdf|xml|html?)$"> FileETag None <ifModule mod_headers.c> Header unset ETag Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate" Header set Pragma "no-cache" Header set Expires "Wed, 11 Jan 1984 05:00:00 GMT" </ifModule> </filesMatch> I copied that regex from someplace in Web months ago. It should add those headers to any HTTP Response that does NOT have those extensions. But it's not working, it's adding them to any Response. I also need to create another directive to add Header set Cache-Control "max-age=3600, public" to Responses of files that DOES have them. Could anybody help me make proper fileMatch regexes?

• Access denied to EFS encrypted files after PC joins domain

  - by mjmarsh

  I'm experiencing strange behavior with Windows Encrypted File System: I have a machine that is in workgroup mode (not joined to a domain) I encrypt an entire directory structure on the machine (basically a folder and subfolders with data files for my application). My application writes and reads files from the encrypted file hierarchy as a local Windows user (let's call the account 'SecureUser'). This works fine I then join the PC to a domain (Let's call it 'TEST') Afterwards, processes running as the local 'SecureUser' account can't read the files it wrote originally when it was off the domain (What is also strange is that the files are listed as "read only" now and I cannot unset this flag via Windows Explorer or the command line, even though it looks like it succeeds) I then 'un-join' the PC from the domain and everything works again Is there something about changing domain membership on a PC that changes the behavior of EFS so that previously encrypted files cannot be read, even by the originating user? Thanks in advance

• psql editor setting on Ubuntu

  - by dezso

  The situation is the following. This is an Ubuntu box: Linux ns3mx3 2.6.32-41-server #89-Ubuntu SMP Fri Apr 27 22:33:31 UTC 2012 x86_64 GNU/Linux Which means that when I first issue \e in psql, I'm asked to choose an editor. Then there is the .selected_editor file, which contains # Generated by /usr/bin/select-editor SELECTED_EDITOR="/usr/bin/mcedit-debian" So far this is OK (it's my problem that I consider this completely useless, but never mind). Then I set up a .psqlrc file: \set PSQL_EDITOR /usr/bin/vim \set EDITOR /usr/bin/vim \set VISUAL /usr/bin/vim As you can see, I wanted to be sure not to miss a candidate variable for editor setting. The file is used as expected: test=# \echo :EDITOR /usr/bin/vim But when I issue the \e command, none of these is used - I fall back to SELECTED_EDITOR. The situation remains just the same if I append an \unset SELECTED_EDITOR to the .psqlrc file. Now how can I make .psqlrc setting win over the default editor? (PostgreSQL version id 9.1.4)

• "Clear Text Credential Access Enabled" field

  - by Dave

  Searching for answers about the "Clear Text Credential Access Enabled" field, I found a question on an oracle forum that was my exactly what I was trying to find out. Thinking that my answer would soon be found, I happily click on the link only to find zero replies. All hope was lost. I am posting the question here, hoping that someone on this site will know the answer. Can somebody please explain the usage of "Clear Text Credential Access Enabled" checkbox under "-Security-Advanced tab for Weblogic 11g? What is the difference if we set or unset this flag? If I dont set this flag I get an exception like "Access to sensitive attribute in clear text is not allowed due to the setting of ClearTextCredentialAccessEnabled attribute in SecurityConfigurationMBean" when I try to set a value for the "Credential" field. But what should be the value for "Credential" field if I dont set the "Clear Text Credential Access Enabled"flag?

• Enum.HasFlag

  - by Scott Dorman

  An enumerated type, also called an enumeration (or just an enum for short), is simply a way to create a numeric type restricted to a predetermined set of valid values with meaningful names for those values. While most enumerations represent discrete values, or well-known combinations of those values, sometimes you want to combine values in an arbitrary fashion. These enumerations are known as flags enumerations because the values represent flags which can be set or unset. To combine multiple enumeration values, you use the logical OR operator. For example, consider the following: public enum FileAccess { None = 0, Read = 1, Write = 2, }   class Program { static void Main(string[] args) { FileAccess access = FileAccess.Read | FileAccess.Write; Console.WriteLine(access); } } The output of this simple console application is: The value 3 is the numeric value associated with the combination of FileAccess.Read and FileAccess.Write. Clearly, this isn’t the best representation. What you really want is for the output to look like: To achieve this result, you simply add the Flags attribute to the enumeration. The Flags attribute changes how the string representation of the enumeration value is displayed when using the ToString() method. Although the .NET Framework does not require it, enumerations that will be used to represent flags should be decorated with the Flags attribute since it provides a clear indication of intent. One “problem” with Flags enumerations is determining when a particular flag is set. The code to do this isn’t particularly difficult, but unless you use it regularly it can be easy to forget. To test if the access variable has the FileAccess.Read flag set, you would use the following code: (access & FileAccess.Read) == FileAccess.Read Starting with .NET 4, a HasFlag static method has been added to the Enum class which allows you to easily perform these tests: access.HasFlag(FileAccess.Read) This method follows one of the “themes” for the .NET Framework 4, which is to simplify and reduce the amount of boilerplate code like this you must write.

• PHP: Proper way of using a PDO database connection in a class

  - by Cortopasta

  Trying to organize all my code into classes, and I can't get the database queries to work inside a class. I tested it without the class wrapper, and it worked fine. Inside the class = no dice. What about my classes is messing this up? class ac { public function dbConnect() { global $dbcon; $dbInfo['server'] = "localhost"; $dbInfo['database'] = "sn"; $dbInfo['username'] = "sn"; $dbInfo['password'] = "password"; $con = "mysql:host=" . $dbInfo['server'] . "; dbname=" . $dbInfo['database']; $dbcon = new PDO($con, $dbInfo['username'], $dbInfo['password']); $dbcon->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $error = $dbcon->errorInfo(); if($error[0] != "") { print "<p>DATABASE CONNECTION ERROR:</p>"; print_r($error); } } public function authentication() { global $dbcon; $plain_username = $_POST['username']; $md5_password = md5($_POST['password']); $ac = new ac(); if (is_int($ac->check_credentials($plain_username, $md5_password))) { ?> <p>Welcome!</p> <!--go to account manager here--> <?php } else { ?> <p>Not a valid username and/or password. Please try again.</p> <?php unset($_POST['username']); unset($_POST['password']); $ui = new ui(); $ui->start(); } } private function check_credentials($plain_username, $md5_password) { global $dbcon; $userid = $dbcon->prepare('SELECT id FROM users WHERE username = :username AND password = :password LIMIT 1'); $userid->bindParam(':username', $plain_username); $userid->bindParam(':password', $md5_password); $userid->execute(); print_r($dbcon->errorInfo()); $id = $userid->fetch(); Return $id; } } And if it's any help, here's the class that's calling it: require_once("ac/acclass.php"); $ac = new ac(); $ac->dbconnect(); class ui { public function start() { if ((!isset($_POST['username'])) && (!isset($_POST['password']))) { $ui = new ui(); $ui->loginform(); } else { $ac = new ac(); $ac->authentication(); } } private function loginform() { ?> <form id="userlogin" action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post"> User:<input type="text" name="username"/><br/> Password:<input type="password" name="password"/><br/> <input type="submit" value="submit"/> </form> <?php } }

• Can't add to panel nor delete panel

  - by david

  Hello everybody! I cannot add any applet to any (top or bottom) panel, cannot delete any panel nor create a new panel. When I right-click on the panel the only options available are: Properties, Help or About panels. [I cannot post an image because of spam prevention, so I'll do my best] I can see when I right-click (bold means clickable): Add to panel Properties Delete this panel New panel Help About Panels Trying to solve this I did what is usually suggested: gconftool-2 –-recursive-unset /apps/panel # might be optional rm -rf ~/.gconf/apps/panel pkill gnome-panel but I only got a nice empty panel (no Applications Places System, no clock, no shutdown button...) to which I couldn't add any applet, so I decided to take the default profiles in .gconf and .gconfd from a live CD and overwrite mines. Now we are back to the beginning. I also have tried to lock completely the panel (with both gconf-editor and pessulus) and later unlock it completely but it didn't work. Here is the system information: $ lsb_release Distributor ID: Ubuntu Description: Ubuntu 10.04.2 LTS Release: 10.04 Codename: lucid Thank you very much.

• How can I reset addAttributeToFilter in Magento searches

  - by Bobby

  I'm having problems getting the addAttributeToFilter function within a loop to behave in Magento. I have test data in my store to support searches for all of the following data; $attributeSelections=array( array('size' => 44, 'color' => 67, 'manufacturer' => 17), array('size' => 43, 'color' => 69, 'manufacturer' => 17), array('size' => 42, 'color' => 70, 'manufacturer' => 17)); And my code to search through these combinations; foreach ($attributeSelections as $selection) { $searcher = Mage::getSingleton('catalogsearch/advanced')->getProductCollection(); foreach ($selection as $k => $v) { $searcher->addAttributeToFilter("$k", array('eq' => "$v")); echo "$k: $v<br />"; } $result=$searcher->getData(); print_r($result); } This loop gives the following results (slightly sanitised for veiwing pleasure); size: 44 color: 67 manufacturer: 17 Array ( [0] => Array ( [entity_id] => 2965 [entity_type_id] => 4 [attribute_set_id] => 28 [type_id] => simple [sku] => 1006-0001 [size] => 44 [color] => 67 [manufacturer] => 17 ) ) size: 43 color: 69 manufacturer: 17 Array ( [0] => Array ( [entity_id] => 2965 [entity_type_id] => 4 [attribute_set_id] => 28 [type_id] => simple [sku] => 1006-0001 [size] => 44 [color] => 67 [manufacturer] => 17 ) ) size: 42 color: 70 manufacturer: 17 Array ( [0] => Array ( [entity_id] => 2965 [entity_type_id] => 4 [attribute_set_id] => 28 [type_id] => simple [sku] => 1006-0001 [size] => 44 [color] => 67 [manufacturer] => 17 ) ) So my loop is function and generating the search. However, the values fed into addAttributeToFilter on the first itteration of the loop seem to remain stored for each search. I've tried clearing my search object, for example, unset($searcher) and unset($result). I've also tried magento functions such as getNewEmptyItem(), resetData(), distinct() and clear() but none have the desired effect. Basically what I am trying to do is check for duplicate products before my script attempts to programatically create a product with these attribute combinations. The array of attribute selections may be of varying sizes hence the need for a loop. I would be very appreiciative if anyone might be able to shed some light on my problem.

• Anomaly with bash PS1 definition

  - by Michael Wiles

  My root and admin user both have the same .bashrc file. The prompt section of the .bashrc is the following: if [ "$color_prompt" = yes ]; then PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ ' else PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ ' fi unset color_prompt force_color_prompt # If this is an xterm set the title to user@host:dir case "$TERM" in xterm*|rxvt*) PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\u@\h: \w\a\]$PS1" ;; *) ;; esac But the problem is that the admin user and root user have different prompts. admin's prompt is: admin@hostname:~$ and root's prompt is root@hostname:/home# So it seems root is using the "xterm" version and admin is not. Why does the .bashrc file have this difference in prompts? How do I get the admin user to also use the xterm version? How would I test that condition? If I run echo $TERM while running as the admin user I get xterm so as far as I can tell, it should be using the xterm version for the admin user.

• Cannot log in to the desktop on ubuntu 11.10?

  - by Jichao

  The problem is, I could log in under the terminal, i could ifup eth0, i could do anything I want in the terminal, but if I use ctrl+alt+f7 goto the gnome login screen, after I input the correct password, the system just send me back to same login screen again. I have created a new user, but it didn't work. I have change all the files under ~/ to jichao:jichao(which is my username) with chown -hR jichao:jichao /home/jichao, but it didn't work too.

• cannot get upstart to run user job

  - by dre

  I am trying to get upstart start a user job during the boot of my machine. I have my conky.conf upstart config file in my $HOME/.init directory. Wenn I run "start conky" I get this error: dre@dre-laptop:~$ start conky start: Rejected send message, 1 matched rules; type="method_call", sender=":1.76" (uid=1000 pid=2843 comm="start conky ") interface="com.ubuntu.Upstart0_6.Job" member="Start" error name="(unset)" requested_reply="0" destination="com.ubuntu.Upstart" (uid=0 pid=1 comm="/sbin/init") dre@dre-laptop:~$ I (think I) know that this error has to do with the d-bus system (authentification). I also read (http://upstart.ubuntu.com/cookbook/#id96) that ubuntu 12.10 already has the right configuration in the d-bus config file "/etc/dbus-1/system.d/Upstart.conf" to allow normal users to use upstart. dre@dre-laptop:~/.init$ cat conky.conf description "conky, a system monitor appled" start on lightdm stop on shutdown # Automatically restart process if crashed respawn # Essentially lets upstart know the process will detach itself to the background #expect fork # Start conky exec /usr/bin/conky So, who knows, what do I do wrong??? greetings Andre No one??? Please... give me your best shot.

• PowerBroker (Likewise-Open) + Ubuntu 13.04 -> 13.10 Upgrade

  - by JoBu1324

  I just upgraded Ubuntu from 13.04 to 13.10, and now I can't log into Active Directory; my system is integrated using PowerBroker Identity Services (PBIS), which used to be called Likewise-Open. So far I have identified the following symptoms: I am able to log in with my credentials via ssh. The screen goes black when attempting log into my account via the login screen.

• App installed in ~/usr launches from terminal but not Applications menu (or why does setting ld_library_path in .profile not work as it should)

  - by levesque

  I have built and installed an application under a directory of my choosing, let's say under /home/jim/usr, so files have been put in three-four folders, all under this $HOME/usr folder (e.g., bin, include, lib, share, etc.). I can launch this application from the command line just fine as I added the proper paths to my environement variables PATH and LD_LIBRARY_PATH in ~/.bashrc. I added the same paths to the ~/.profile file, which, if I'm not mistaken, is supposed to be parsed by Ubuntu. Doesn't work. Nothing. Where can I go from there? EDIT: I logged out/in and restarted my computer. Both didn't change a thing. The problem seems to come from the fact that no matter what I do the LD_LIBRARY_PATH environment variable is not properly passed to Ubuntu. Using log files, I found that the application I'm trying to run in this example doesn't find one it's dependencies located in ~/usr/lib. One solution would be to add the /home/jim/usr/lib folder inside a file located in /etc/ld.so.conf.d/, but I don't have admin rights on this machine. Making a wrapper script like this one works: #!/bin/bash export LD_LIBRARY_PATH=$HLOC/usr/lib application &> $HOME/application_messages.log but that would force me to wrap all my home compiled applications with this script. Any ideas? Why does Ubuntu/Gnome remove the LD_LIBRARY_PATH environment variable from my set variables? Is it because trying to do this is bad practice? UPDATE (and solution): As found by Christopher, there is a bug report about this on launchpad. LD_LIBRARY_PATH is unset after parsing of the ~/.profile file. See the bug report. Seems the only solution for now is to make a wrapper script.

• Recursing data into a 2 dimensional array in PHP 5

  - by user315699

  I'm getting bamboozled by "for each" loops and two dimensional arrays, and I'm a php newb so please bear with me (and ignore any variables with the word "image" - it's all about the mp3s, I just didn't change it from the xml tutorial) I found a php function on the net that list files in a directory, the output of which is: Array ( [0] = audio/1.mp3 [1] = audio/2.mp3 [2] = audio/3.mp3 [3] = audio/4.mp3 [4] = audio/5.mp3 ) As expected. And another that lists some info about mp3 files. $mp3datafile = 'audio/1.mp3'; $m = new mp3file($mp3datafile); $mp3dataArray = $m-get_metadata(); print_r($mp3dataArray); unset($mp3dataArray); The output of which is Array ( [Filesize] = 31972 [Encoding] = CBR [etc] ) In order to automatically build RSS for a podcast, I need to generate XML for each item. So far so good. This is how I'm making the xml foreach ($imagearray as $key = $val) { $tnsoundfile = $xml_generator-addChild('item'); $tnsoundfile-addChild('title', $podcasttitle); $enclosure = $tnsoundfile-addChild('enclosure'); $enclosure-addAttribute('url', $val); // that's the filename $enclosure-addAttribute('length', $mp3dataArray[Filesize]); // << Length is file length, not time. But later I also need $mp3dataArray[Length mm:ss] for duration tag. $enclosure-addAttribute('type', 'audio/mpeg'); $tnsoundfile-addChild('guid', $path_to_image_dir.'/'.$val); } (The above has been truncated, I realise it's not proper xml right now, but it was just to show what was going on). Perfect. But I need to do it for as many files as there are in the directory. So, I have an array of the names of the files in the directory in $mp3data And, I have an array of mp3 data in $mp3dataArray from one iteration of the get_metadata() function. If I do the following, then I get a nice list of the mp3 data of the 5 files in the directory: foreach ($mp3data as $key = $val) { $mp3datafile = $val; $m = new mp3file($mp3datafile); $mp3dataArray = $m-get_metadata(); print_r($mp3dataArray); unset($mp3dataArray); } As expected. Where I'm struggling, and have been for most of the day in spite of reading many forums and tutorials, is how to populate the "second dimension" of the array, so that it goes through 1,2,3,4 and 5.mp3 (or however many there are), extracts the metadata, then allows me to use it in the xml section above. Here's what I have foreach ($mp3data as $key = $val) { $mp3datafile = $val; $m = new mp3file($mp3datafile); $mp3dataArray = $m-get_metadata(); $mp3testarray = array($mp3dataArray); } print_r($mp3dataArray); Shouldn't that line print_r($mp3dataArray); give me a nice list of 5 lots of mp3 data, in the way it did when I recursed through the loop as before? Cos this is driving me nuts! It must be something so simple, and any help would be greatly appreciated. Thank you in advance.

• VNC grey screen and start on boot 12.04

  - by Siriss

  I have 12.04 LTS installed and I am trying to get VNC to work. I want to be able to connect to existing sessions, and have it start on boot. I followed this guide and have left a comment to try and fix my problems but no dice. I have also tried all solutions I have found on google, including the one here, but I could not get it to work (I am missing something easy I am sure). When I connect to the VNC session I get a grey screen with three checkboxes: Accept clipboard from viewers Send clipboard to viewers Send primary selection to viewers Here is my xstartup: #!/bin/sh # Uncomment the following two lines for normal desktop: unset SESSION_MANAGER # exec /etc/X11/xinit/xinitrc gnome-session -session=gnome-classic & [ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources xsetroot -solid grey vncconfig -iconic & #x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" & #x-window-manager & I have also edited my to include: /usr/bin/vncserver -geometry 1024x768 It does not start on boot, but when I run the command it starts, but I get the grey screen. Any help would be greatly appreciated. Thank you!!

• How to make a jQuery plugin (the right way)?

  - by macek

  I know there are jQuery cookie plugins out there, but I wanted to write one for the sake of better learning the jQuery plugin pattern. I like the separation of "work" in small, manageable functions, but I feel like I'm passing name, value, and options arguments around too much. Is there a way this can be refactored? I'm looking for snippets of code to help illustrate examples provided with in answers. Any help is appreciated. Thanks :) example usage $.cookie('foo', 'bar', {expires:7}); $.cookie('foo'); //=> bar $.cookie('foo', null); $.cookie('foo'); //=> undefined Edit: I did a little bit of work on this. You can view the revision history to see where this has come from. It still feels like more refactoring can be done to optimize the flow a bit. Any ideas? the plugin (function($){ $.cookie = function(name, value, options) { if (typeof value == 'undefined') { return get(name); } else { options = $.extend({}, $.cookie.defaults, options || {}); return (value != null) ? set(name, value, options) : unset(name, options); } }; $.cookie.defaults = { expires: null, path: '/', domain: null, secure: false }; var set = function(name, value, options){ console.log(options); return document.cookie = options_string(name, value, options); }; var get = function(name){ var cookies = {}; $.map(document.cookie.split(';'), function(pair){ var c = $.trim(pair).split('='); cookies[c[0]] = c[1]; }); return decodeURIComponent(cookies[name]); }; var unset = function(name, options){ value = ''; options.expires = -1; set(name, value, options); }; var options_string = function(name, value, options){ var pairs = [param.name(name, value)]; $.each(options, function(k,v){ pairs.push(param[k](v)); }); return $.map(pairs, function(p){ return p === null ? null : p; }).join(';'); }; var param = { name: function(name, value){ return name + "=" + encodeURIComponent(value); }, expires: function(value){ // no expiry if(value === null){ return null; } // number of days else if(typeof value == "number"){ d = new Date(); d.setTime(d.getTime() + (value * 24 * 60 * 60 * 1000)); } // date object else if(typeof value == "object" && value instanceof "Date") { d = value; } return "expires=" + d.toUTCString(); }, path: function(value){ return "path="+value; }, domain: function(value){ return value === null ? null : "domain=" + value; }, secure: function(bool){ return bool ?

• Help with refactoring PHP code

  - by Richard Knop

  I had some troubles implementing Lawler's algorithm but thanks to SO and a bounty of 200 reputation I finally managed to write a working implementation: http://stackoverflow.com/questions/2466928/lawlers-algorithm-implementation-assistance I feel like I'm using too many variables and loops there though so I am trying to refactor the code. It should be simpler and shorter yet remain readable. Does it make sense to make a class for this? Any advice or even help with refactoring this piece of code is welcomed: <?php /* * @name Lawler's algorithm PHP implementation * @desc This algorithm calculates an optimal schedule of jobs to be * processed on a single machine (in reversed order) while taking * into consideration any precedence constraints. * @author Richard Knop * */ $jobs = array(1 => array('processingTime' => 2, 'dueDate' => 3), 2 => array('processingTime' => 3, 'dueDate' => 15), 3 => array('processingTime' => 4, 'dueDate' => 9), 4 => array('processingTime' => 3, 'dueDate' => 16), 5 => array('processingTime' => 5, 'dueDate' => 12), 6 => array('processingTime' => 7, 'dueDate' => 20), 7 => array('processingTime' => 5, 'dueDate' => 27), 8 => array('processingTime' => 6, 'dueDate' => 40), 9 => array('processingTime' => 3, 'dueDate' => 10)); // precedence constrainst, i.e job 2 must be completed before job 5 etc $successors = array(2=>5, 7=>9); $n = count($jobs); $optimalSchedule = array(); for ($i = $n; $i >= 1; $i--) { // jobs not required to precede any other job $arr = array(); foreach ($jobs as $k => $v) { if (false === array_key_exists($k, $successors)) { $arr[] = $k; } } // calculate total processing time $totalProcessingTime = 0; foreach ($jobs as $k => $v) { if (true === array_key_exists($k, $arr)) { $totalProcessingTime += $v['processingTime']; } } // find the job that will go to the end of the optimal schedule array $min = null; $x = 0; $lastKey = null; foreach($arr as $k) { $x = $totalProcessingTime - $jobs[$k]['dueDate']; if (null === $min || $x < $min) { $min = $x; $lastKey = $k; } } // add the job to the optimal schedule array $optimalSchedule[$lastKey] = $jobs[$lastKey]; // remove job from the jobs array unset($jobs[$lastKey]); // remove precedence constraint from the successors array if needed if (true === in_array($lastKey, $successors)) { foreach ($successors as $k => $v) { if ($lastKey === $v) { unset($successors[$k]); } } } } // reverse the optimal schedule array and preserve keys $optimalSchedule = array_reverse($optimalSchedule, true); // add tardiness to the array $i = 0; foreach ($optimalSchedule as $k => $v) { $optimalSchedule[$k]['tardiness'] = 0; $j = 0; foreach ($optimalSchedule as $k2 => $v2) { if ($j <= $i) { $optimalSchedule[$k]['tardiness'] += $v2['processingTime']; } $j++; } $i++; } echo '<pre>'; print_r($optimalSchedule); echo '</pre>';

• Allow non-sudo group to control Upstart job

  - by Angle O'Saxon

  I'm trying to set up an Upstart job to run on system startup, and that can also be started/stopped by members of a group other than sudo. With a previous version, I usedupdate-rc.d and scripts stored in /etc/init.d/ to get this working by adding %Group ALL = NOPASSWD: /etc/init.d/scriptname to my sudoers file, but I can't seem to get an equivalent working for Upstart. I tried adding %Group ALL = NOPASSWD: /sbin/initctl start jobname to the sudoers file, but trying to run the command start jobname produces this error: start: Rejected send message, 1 matched rules; type="method_call", sender=":1.21" (uid=1000 pid=5148 comm="start jobname " interface="com.ubuntu.Upstart0_6.Job" member="Start" error name="(unset)" requested_reply="0" destination="com.ubuntu.Upstart" (uid=0 pid=1 comm="/sbin/init") As near as I can tell, that's a complaint about how my user account isn't given the power to send 'Start' messages in the D-Bus config file for Upstart. I haven't been able to actually find any information on how to edit that file to give a group permission to access a specific service--does such an option exist? Is there a way to edit the Sudoers file so I can run the job without editing the config file? Am I better off just sticking with the previous version?

• How to refactor to cleaner version of maintaing states of the widget

  - by George

  Backstory I inherited a bunch of code that I'd like to refactor. It is a UI application written in javascript. Current state: We have main application which consist of several UI components. And each component has entry fields, textboxes, menus, etc), like "ticket", "customer information", etc. Based on input, where the application was called from, who is the user, we enable/disable, hide, show, change titles. Unfortunately, the app grew to the point where it is really hard to scale, add new features. Main the driver (application code) calls set/unset functions of the respective components. So a lot of the stuff look like this Main app unit function1() { **call_function2()** component1.setX(true); component1.setY(true); component2.setX(false); } call_function2() { // it may repeat some of the code function1 called } and we have a lot of this in the main union. I am cleaning this mess. What is the best way to maintain the state of widgets? Please let me know if you need me to clarify.
