• Install system-wide PEAR on Debian Lenny

  - by artvolk

  Good day! I've installed PEAR on Debian Lenny using apt-get install php-pear, it was installed in /usr/share/php When I try to install anything using pear install <package> the PEAR folder is created under current user home directory and separate copy of pear is installed there. I ended up by installing local copy of PEAR for one of the users like this: http://kuziel.info/log/archives/2006/04/01/Installation-of-local-PEAR-repository Is any way to tell pear to install packages to system-wide repository in /usr/share/php? What is the recommended way of using system-wide PEAR copy? Thanks in advance!

• Upgrading openSUSE 11.1 with Plesk Panel 9.3 to PHP 5.3

  - by Jonathan

  I'm running a VPS with openSUSE 11.1 (i586). On the VPS is Parallels Plesk Panel 9.3.0 installed. The current PHP-version is PHP 5.2.11. I want to upgrade PHP to PHP 5.3, but I can't find good instructions on how to do this. If I check for updates in Zypper, it says this is the latest release. In the Plesk Updates isn't an update either, both via the webbased interface and the command line interface. On Software.openSUSE.org I can find packages for PHP 5.3.1 in both the server:php/server_apache_openSUSE_11.1-repo and the server:php/openSUSE_11.1-repo (can't post the link because I'm a newbie here). But if I add one of those to Zypper, I still don't see an update. Is there here somebody who knows how to do this? And is it completely safe to update that way? I don't want to end up with a broken VPS... Thanks! Jonathan

• Switching from Java/Java EE career path to C POS path?

  - by Muhammad

  I am a Java/Java EE Developer with about 3 years in this field. I like low-level programming so much... I favor back-end code over front-end. I've a knowledge in C and know little about C++. I got an offer to work with C in Point-of-Sale Payment terminals. I don't know much about how POS works (IDE/toolsets, etc). although I have a payment experience (ISO8583, etc...) I need you own opinion from Switching from the Java's High-level world to POS low-level world Although I love low-level world, but I am afraid from not being found what I seek.. I know programmers are not measured by the tools they use (including prog. langs.) but with their minds. I need your opinions of: Is programming POS terminals in C is an interesting thing, or I'll find myself doing usual code-writing job? (especially I am about to switch my whole career path). I find myself writing an elegant code in Java (like: Sobat http://code.google.com/p/sobat/) a code where I find myself in... So do I'll find the same thing in POS C? or It will all about Libraries that I'll call to finish my work?! Lastly, does this thing worse adventure with my current career (stability, conference, etc.. )? (as I currently don't think to move to a new job) Thanks.

• OSX 10.8 Corrupted User Account Using Launchctl

  - by Scott

  I used the following command: launchctl unload -w /System/Library/LaunchAgents/com.apple.notificationcenterui.plist in an attempt to disable notification center. I'm not sure that I got all of the commands right and appear to have corrupted the account that I executed it from - I get a grey screen when I try to login on that account. Fortunately I have another account on the machine with admin privileges so I can still use the machine. I would however like to restore the account to a working condition preferably without having to resort to a complete system restore from my time machine backup. Is there a way of diagnosing the current status of this launchagent and returning it to its original state?

• HTML5 point and click adventure game code structure with CreateJS

  - by user1612686

  I'm a programming beginner. I made a tiny one scene point and click adventure game to try to understand simple game logic and came up with this: CreateJS features prototypes for creating bitmap images, sprites and sounds objects. I create them and define their properties in a corresponding function (for example images(); spritesheets(), sounds()...). I then create functions for each animation sequence and "game level" functions, which handle user interactions and play the according animations and sounds for a certain event (when the level is complete, the current level function calls the next level function). And I end up with quite the mess. What would be the "standard (if something like that exists)" OOP approach to structure simple game data and interactions like that? I thought about making game.images, game.sprites, game.sounds objects, which contain all the game data with its properties using CreateJS constructors. game.spriteAnimations and game.tweenAnimations objects for sprite animations and tweens and a game.levelN object, which communicates with a game.interaction object, processing user interaction. Does this make any sense? How do you structure your simple game code? Thanks in advance!

• Runaway version store in tempdb

  - by DavidWimbush

  Today was really a new one. I got back from a week off and found our main production server's tempdb had gone from its usual 200MB to 36GB. Ironically I spent Friday at the most excellent SQLBits VI and one of the sessions I attended was Christian Bolton talking about tempdb issues - including runaway tempdb databases. How just-in-time was that?! I looked into the file growth history and it looks like the problem started when my index maintenance job was chosen as the deadlock victim. (Funny how they almost make it sound like you've won something.) That left tempdb pretty big but for some reason it grew several more times. And since I'd left the file growth at the default 10% (aaargh!) the worse it got the worse it got. The last regrowth event was 2.6GB. Good job I've got Instant Initialization on. Since the Disk Usage report showed it was 99% unallocated I went into the Shrink Files dialogue which helpfully informed me the data file was 250MB.  I'm afraid I've got a life (allegedly) so I restarted the SQL Server service and then immediately ran a script to make the initial size bigger and change the file growth to a number of MB. The script complained that the size was smaller than the current size. Within seconds! WTF? Now I had to find out what was using so much of it. By using the DMV sys.dm_db_file_space_usage I found the problem was in the version store, and using the DMV sys.dm_db_task_space_usage and the Top Transactions by Age report I found that the culprit was a 3rd party database where I had turned on read_committed_snapshot and then not bothered to monitor things properly. Just because something has always worked before doesn't mean it will work in every future case. This application had an implicit transaction that had been running for over 2 hours.

• How to remove package from apt-get autoremove "queue"

  - by Darth

  I just installed Calibre for ebook management via apt-get on Ubuntu 10.04, however I found out that it's one major version behind the current release, so I decided to reinstall it directly from sources. When I uninstalled the packaged version, apt added bunch of dependencies to the autoremove queue, and as I installed newer version of Calibre from sources, it has no knowledge of it being dependent on those packages. Now I basically have all libraries that I want, but they are still in the autoremove queue. The following packages were automatically installed and are no longer required: libqt4-script libqt4-designer libqt4-dbus python-lxml python-cherrypy3 python-encutils libqt4-xmlpatterns libqt4-help python-qt4 python-clientform python-sip python-django python-mechanize libqt4-svg python-django-tagging libphonon4 libqt4-xml libqt4-assistant libqt4-webkit libqt4-scripttools python-beautifulsoup python-pypdf python-dateutil python-cssutils Use 'apt-get autoremove' to remove them. How do I tell apt that I want to keep these packages installed, without reinstalling them manually?

• Disable Memory Modules In BIOS for Testing Purposes (Optimize Nehalem/Gulftown Memory Performance)

  - by Bob

  I recently acquired an HP Z800 with two Intel Xeon X5650 (Gulftown) 6 core processors. The person that configured the system chose 16GB (8 x 2GB DDR3-1333). I'm assuming this person was unaware these processors have 3 memory channels and to optimize memory performance one should choose memory in multiples of three. Based on this information, I have a question: By entering the BIOS, can I disable the bank on each processor that has the single memory module? If so, will this have any adverse effects or behave differently than physically removing the modules? I ask due to the fact that I prefer to store the extra memory in the system if it truly behaves as if the memory is not even there. Also, I see this as an opportunity to test 12GB vs. 16GB to see if there is a noticeable difference. Note: According to http://www.delltechcenter.com/page/04-08-2009+-+Nehalem+and+Memory+Configurations?t=anon, the current configuration reduces the overall data transfer speed to 1066 and in addition, the memory bandwidth goes down by about 23%.

• Booting from USB on Mac Air (using setup_mac_usb_boot.sh)

  - by Mike O

  So, I've been working on this for hours and it's getting a little tiring. As some of you may know, installing Ubuntu on Macs is frequently an adventure, and I'm experiencing that right now. The part I'm hung up on at the moment is making a bootable USB. I would just use a CD, but my laptop is a MacBook Air (which doesn't have a CD drive), and I don't own an external CD drive. I initially attempted to use the command line method supplied by the Ubuntu documentation here: https://help.ubuntu.com/community/How%20to%20install%20Ubuntu%20on%20MacBook%20using%20USB%20Stick However, that wasn't even recognized by rEFIt even when I made a number of different modifications to the process, so I quickly decided to look elsewhere. I came across this guide: https://help.ubuntu.com/community/MacBookAir4-2#Basic_Installation_Instructions This ended up working to a large extent. If I choose the supplied grub from rEFIt, it will bring me to the Ubuntu grub, asking me to try it, install, or check the disk. And if I choose to boot Linux directly from rEFIt, it will bring me to the language selection menu. But when I make my selection from either of these menus it pauses for about ten seconds and then gives me a command line error message. It begins with kernel panic - not syncing timer doesn't work through interrupt, and then shows about eight file names. Does anyone here have any ideas as to what can be causing this? I also tried the script with both Ubuntu 11.10 (the current version when the script was written) and 12.04.

  Hello everyone, I am using a MacBook Pro running Mac OS X 10.5. I am new to this development environment, and previously worked on Windows. I have tried that Fn + Right arrow on Mac works as "END" key on Windows -- which makes cursor move to the end of line, for most application like Word for Mac -- I have tried it works. But I tried Fn + Right Arrow does not work for current question input box of SuperUser. I am wondering how to solve this issue and why? Does anyone have the same issue for me? thanks in advance, George

• Architecting Python application consisting of many small scripts

  - by Duke Dougal

  I am building an application which, at the moment, consists of many small Python scripts. Each Python script processes items from one Amazon SQS queue. Emails come into an initial queue and are processed by a script and typically the script will do a small unit of processing (for example, parse email and store some database fields), then an item will be placed on the next queue for further processing, until eventually the email has finished going through the various scripts and queues. What I like about this approach is that it is very loosely coupled. However, I'm not sure how I should implement live. Should I make each script a daemon which is constantly polling it's inbound queue for things to do? Or should there be some overarching orchestration program or process? Or maybe I should not have lots of small Python scripts but one large application? Specific questions: How should I run each of these scripts - as a daemon with some sort or restart monitor to restart them in case they stop for any reason? If yes, should I have some program which orchestrates this? Or is the idea of many small script not a good one, would it make more sense to have a larger python program which contains all the functionality and does all the queue polling and execution of functionality for each queue? What is the current preferred approach to daemonising Python scripts? Broadly I would welcome any comments or opinions on any aspect of this. thanks

• Wake On Lan (WOL) for Realtek RTL8101E/RTL8102E

  I'm unsuccessfully trying to get Wake on Lan to work with my local server (IP Address : 192.168.0.2, distro Ubuntu 12.04.3 LTS) which has a Realtek RTL8101E/RTL8102E ethernet card.

• SQL SERVER – Weekly Series – Memory Lane – #039

  - by Pinal Dave

  Here is the list of selected articles of SQLAuthority.com across all these years. Instead of just listing all the articles I have selected a few of my most favorite articles and have listed them here with additional notes below it. Let me know which one of the following is your favorite article from memory lane. 2007 FQL – Facebook Query Language Facebook list following advantages of FQL: Condensed XML reduces bandwidth and parsing costs. More complex requests can reduce the number of requests necessary. Provides a single consistent, unified interface for all of your data. It’s fun! UDF – Get the Day of the Week Function The day of the week can be retrieved in SQL Server by using the DatePart function. The value returned by the function is between 1 (Sunday) and 7 (Saturday). To convert this to a string representing the day of the week, use a CASE statement. UDF – Function to Get Previous And Next Work Day – Exclude Saturday and Sunday While reading ColdFusion blog of Ben Nadel Getting the Previous Day In ColdFusion, Excluding Saturday And Sunday, I realize that I use similar function on my SQL Server Database. This function excludes the Weekends (Saturday and Sunday), and it gets previous as well as next work day.

DBCC SHRINKFILE Takes Long Time to Run If you are DBA who are involved with Database Maintenance and file group maintenance, you must have experience that many times DBCC SHRINKFILE operations takes a long time but any other operations with Database are relatively quicker. mssqlsystemresource – Resource Database The purpose of resource database is to facilitates upgrading to the new version of SQL Server without any hassle. In previous versions whenever version of SQL Server was upgraded all the previous version system objects needs to be dropped and new version system objects to be created. 2009 Puzzle – Write Script to Generate Primary Key and Foreign Key In SQL Server Management Studio (SSMS), there is no option to script all the keys. If one is required to script keys they will have to manually script each key one at a time. If database has many tables, generating one key at a time can be a very intricate task. I want to throw a question to all of you if any of you have scripts for the same purpose. Maximizing View of SQL Server Management Studio – Full Screen – New Screen I had explained the following two different methods: 1) Open Results in Separate Tab - This is a very interesting method as result pan shows up in a different tab instead of the splitting screen horizontally. 2) Open SSMS in Full Screen - This works always and to its best. Not many people are aware of this method; hence, very few people use it to enhance performance. 2010 Find Queries using Parallelism from Cached Plan T-SQL script gets all the queries and their execution plan where parallelism operations are kicked up. Pay attention there is TOP 10 is used, if you have lots of transactional operations, I suggest that you change TOP 10 to TOP 50 This is the list of the all the articles in the series of computed columns.

Look at the simple question – ‘What is the toughest challenge you have faced in your present job and how did you handle it’? and its various answers. Each answer has its own story. SQL SERVER – Interview Questions and Answers – Guest Post by Rick Morelan – Day 27 of 31 Rick Morelan of Joes2Pros has written an excellent blog post on the subject how to find top N values. Most people are fully aware of how the TOP keyword works with a SELECT statement. After years preparing so many students to pass the SQL Certification I noticed they were pretty well prepared for job interviews too. Yes, they would do well in the interview but not great. There seemed to be a few questions that would come up repeatedly for almost everyone. Rick addresses similar questions in his lucid writing skills. 2012 Observation of Top with Index and Order of Resultset SQL Server has lots of things to learn and share. It is amazing to see how people evaluate and understand different techniques and styles differently when implementing. The real reason may be absolutely different but we may blame something totally different for the incorrect results. Read the blog post to learn more. How do I Record Video and Webcast How to Convert Hex to Decimal or INT Earlier I asked regarding a question about how to convert Hex to Decimal. I promised that I will post an answer with Due Credit to the author but never got around to post a blog post around it. Read the original post over here SQL SERVER – Question – How to Convert Hex to Decimal. Query to Get Unique Distinct Data Based on Condition – Eliminate Duplicate Data from Resultset The natural reaction will be to suggest DISTINCT or GROUP BY. However, not all the questions can be solved by DISTINCT or GROUP BY. Let us see the following example, where a user wanted only latest records to be displayed. Let us see the example to understand further.

• Scripting a Windows 2008 Cluster from Windows 2003

  - by glancep

  Our current environment is all Windows 2003. When we migrate a new version of our service to the cluster, we first stop the service with a command like: cluster.exe <clusterName> resource "<serviceName>" /offline We do similarly after the migrate to bring the service back online. Now, we are upgrading our environment to new Windows 2008 servers. However, our build/migrate machine will remain Windows 2003. When issuing the same command from Windwos 2003 to Windows 2008, we get: System error 1722 has occurred (0x000006ba). The RPC server is unavailable. We need to be able to remotely administer a Windows 2008 cluster from a Windows 2003 server in an automated fashion (such as the command-line cluster.exe utility). Is this possible? Thanks, Gideon

  I'm trying to upgrade the Samba server on a Slackware 12 box to serve as PDC for Windows 7 32bit machines (it now has a 3.0.3 and does the job for Win XP machines, but 7 refuses to join the domain - I'm posting this after having tried a few dozen hacks on the windows registry). I'm a newbie on Slackware (I usually dwell in Ubuntu) so I may be going about this the wrong way but this is what I've done so far: The Samba wiki has a couple of hacks for the registry and also seems to suggest a version later than 3.3 (though not in so many words) http://wiki.samba.org/index.php/Windows7 Having scoured the net for later Samba binaries for Slackware 12 and gotten precisely nowhere, I decided that maybe I could compile the blessed thing. But I keep on getting compiler errors. I'm using this SlackBuild script http://ftp.twaren.net/Linux/slackware/slackware-current/source/n/samba/samba.SlackBuild Is there a better way to make this happen? (without upgrading the base system? it has so many finely tuned things running that I don't want to mess with the rest of the setup).

• Few basic Billing facts

  - by Rajesh Sharma

  Quick basic points on Billing: In batch billing, there can be one and ONLY ONE bill for an Account, per Bill Cycle. If an Account has been already billed within the current Bill Cycle's window period, it will not be billed again and will be skipped by the Bill Segment generation program, part of batch eligibility check routine. If an Account does not have any Stopped Service Agreements and you attempt to generate a Bill for that Account that too for a period for which it was already billed, no Bill Segments are generated and a Pending Bill is created for that Account. If a Pending Bill exists for an Account and was generated from a batch, the Account will be re-billed in the next batch run. In contrast, if a Pending Bill exists for an Account and was generated online, the Account will be skipped in the next batch run of the Account's Bill Cycle. Bill generation source, Batch or Online at DB level is determined as following: Batch = CI_BILL.BILL_CYC_CD = {Bill Cycle Code} and CI_BILL.WIN_START_DT = {Window Start Date} Online = CI_BILL.BILL_CYC_CD = "" and CI_BILL.WIN_START_DT IS NULL Bill generation source, Batch or Online from Bill page is determined as following: Batch Online   Closing/Final Bill segment is generated for Stopped Service Agreements and is determined as follows: DB level CI_BSEG.CLOSING_BSEG_SW = "Y" Bill Segment page

• Sharing an Apache configuration between testing vs. production

  - by Kevin Reid

  I have a personal web site with a slightly nontrivial Apache configuration. I test changes on my personal machine before uploading them to the server. The path to the files on disk and the root URL of the site are of course different between the test and production conditions, and they occur many places in the configuration (especially <Directory blocks for special locations which have scripts or no directory listing or ...). What is the best way to share the common elements of the configuration, to make sure that my production environment matches my test environment as closely as possible? What I've thought of is to use SetEnv to store the paths for the current machine in environment variables, then Include a common configuration file with ${} everywhere there's something machine specific. Any hazards of this method?

• SQL SERVER – 2011 – Multi-Monitor SSMS Windows

  - by pinaldave

  I have a dual screen arrangement at my home system. I love it because it’s very convenient. When I am working with SQL Server 2008 R2 or any earlier versions, I would want to use both of the Monitor so I open two separate SQL Server Management Studio and work along with it. I have no complaints with my system, at all. I am totally fine with it. However, sometimes I face small issues, like when I just want a small code open in a separate window but I do not want the windows to take over the whole of another window. But then again, I am already used to this current system. Recently when I was working with SQL Server 2011 ‘Denali’ CTP1, I dragged one of the windows by accident, and suddenly it magically appeared out of its ‘Shell’ of SSMS and was appearing on a separate monitor. I played around a bit and figured out that SSMS now supports multi-monitor (or multi screen) support with single SSMS instance. We can now drag out and drag in any window and resize them at any size. Fantastic! If you are multi-monitor user, I am sure you will like this feature. This leads me to ask you question? Do you use multi-monitor system while working with SQL Server? Leave a quick comment.

• .NET CoffeeScript Handler

  - by Liam McLennan

  After more time than I care to admit I have finally released a rudimentary Http Handler for serving compiled CoffeeScript from Asp.Net applications. It was a long and painful road but I am glad to finally have a usable strategy for client-side scripting in CoffeeScript. Why CoffeeScript? As Douglas Crockford discussed in detail, Javascript is a mixture of good and bad features. The genius of CoffeeScript is to treat javascript in the browser as a virtual machine. By compiling to javascript CoffeeScript gets a clean slate to re-implement syntax, taking the best of javascript and ruby and combining them into a beautiful scripting language. The only limitation is that CoffeeScript cannot do anything that javascript cannot do. Here is an example from the CoffeeScript website. First, the coffeescript syntax: reverse: (string) -> string.split('').reverse().join '' alert reverse '.eeffoC yrT' and the javascript that it compiles to: var reverse; reverse = function(string) { return string.split('').reverse().join(''); }; alert(reverse('.eeffoC yrT')); Areas For Improvement ;) The current implementation is deeply flawed, however, at this point I’m just glad it works. When the server receives a request for a coffeescript file the following things happen: The CoffeeScriptHandler is invoked If the script has previously been compiled then the compiled version is returned. Else it writes a script file containing the CoffeeScript compiler and the requested coffee script The process shells out to CScript.exe to to execute the script. The resulting javascript is sent back to the browser. This outlandish process is necessary because I could not find a way to directly execute the coffeescript compiler from .NET. If anyone can help out with that I would appreciate it.

• Is it possible to skip .rvmrc confirmation?

  - by Viacheslav Molokov

  We are using RVM for managing Ruby installations and environments. Usually we are using this .rvmrc script: #!/bin/bash if [ ! -e '.version' ]; then VERSION=`pwd | sed 's/[a-z/-]//g'` echo $VERSION > .version rvm gemset create $VERSION fi VERSION=`cat .version` rvm use 1.9.2@$VERSION This script forces RVM to create new gem environment for each our project/version. But each time we was deploying new version RVM asks us to confirm new .rvmrc file. When we cd to this directory first time, we are getting something like: =============================================================== = NOTICE: = =============================================================== = RVM has encountered a not yet trusted .rvmrc file in the = = current working directory which may contain nasty code. = = = = Examine the contents of this file to be sure the contents = = are good before trusting it! = = = = Press 'q' to exit the reader when finished reading the file = =============================================================== (press enter to continue when ready) This is not as bad for development environments, but with auto deploy it require to manually confirm each new version on each server. Is it possible to skip this confirmation?

• Setting up Google Analytics for multiple subdomains

  - by Andrew G. Johnson

  so first here's a snippet of my current Analytics javascript: var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-30490730-1']); _gaq.push(['_setDomainName', '.apartmentjunkie.com']); _gaq.push(['_setSiteSpeedSampleRate', 100]); _gaq.push(['_trackPageview']); (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js'; var s = document.getElementsByTagName('script')[0];s.parentNode.insertBefore(ga, s); })(); So if you wanna have a quick peak at the site the url is ApartmentJunkie.com, keep in mind the site is pretty bare bones but you'll get the idea -- basically it's very similar to craigslist in the sense that it's in the local space so people pick a city then get sent to a subdomain that is specific for that city, e.g. winnipeg.mb.apartmentjunkie.com. I put that up late last night then had a look at the analytics and found that I am seeing only the request uri portion of the URLs in analytics as I would with any other site only with this one it's a problem as winnipeg.mb.apartmentjunkie.com/map/ and brandon.mb.apartmentjunkie.com/map/ are two different pages and shouldn't be lumped together as /map/ I know the kneejerk response is likely going to be "hey just setup a different google analytics profile for each subdomain" but there will eventually be a lot of subdomains so google's cap of 50 is going to be too limited and even more important I want to see the data in aggregate for the most part. I am thinking of making a change to the javascript, to something like: _gaq.push(['_trackPageview',String(document.domain) + String(document.location)]); But am unsure if this is the best way and figured someone else on wm.se would have had a similar situation that they could talk a bit about.
