• High disk time on sql-server

  - by Patrik

  Hi We have a dedicated sql-server 2008 r2 enterprise edition. The setup is: D: (data files) - stored on local ssd disks (not the same disks as log files) (raid 10) E: (log files) - stored on local ssd disks (not the same disks as data files) (raid 1) F: (transaction log backup) - stored remote on a SAN Today we moved our log files to new disks (from F: to E:). From a shared volume ( F:(SAN)) to dedicated local disks (E:). What then happend was that the "disk time", "avg. transfer time" and "avg disk write queue length" increased on the volume where we have the data files (D:) (not on the volume where the log files are located). The data volume and log volume does not share disks, however they share the same controller card. "Disk idle time" is low for all volumes. One thought is ofcourse that the controller card might be overloaded. But, we need more ideas on where the problem might be.

• Purpose oriented user accounts on a single desktop?

  - by dd_dent

  Starting point: I currently do development for Dynamics Ax, Android and an occasional dabble with Wordpress and Python. Soon, I'll start a project involving setting up WP on Google Apps Engine. Everything is, and should continue to, run from the same PC (running Linux Mint). Issue: I'm afraid of botching/bogging down my setup due to tinkering/installing multiple runtimes/IDE's/SDK's/Services, so I was thinking of using multiple users, each purposed to handle the task at hand (web, Android etc) and making each user as inert as possible to one another. What I need to know is the following: Is this a good/feasible practice? The second closest thing to this using remote desktops connections, either to computers or to VM's, which I'd rather avoid. What about switching users? Can it be made seamless? Anything else I should know? Update and clarification regarding VM's and whatnot: The reason I wish to avoid resorting to VM's is that I dislike the performance impact and sluggishness associated with it. I also suspect it might add a layer of complexity I wish to avoid. This answer by Wyatt is interesting but I think it's only partly suited for requirements (web development for example). Also, in reference to the point made about system wide installs, there is a level compromise I should accept as experessed by this for example. This option suggested by 9000 is also enticing (more than VM's actually) and by no means do I intend to "Juggle" JVMs and whatnot, partly due to the reason mentioned before. Regarding complexity, I agree and would consider what was said, only from my experience I tend to pollute my work environment with SDKs and runtimes I tried and discarded, which would occasionally leave leftovers which cause issues throught the session. What I really want is a set of well defined, non virtualized sessions from which I can choose at my leisure and be mostly (to a reasonable extent) safe from affecting each session from the other. And what I'm really asking is if and how can this be done using user accounts.

• Varnish doesn't seem to be caching

  - by Charlie Somerville

  I've setup a Varnish cache mirror to sit in front of a file server, but it seems to be endlessly re-downloading data from my file server. There's about 100GB of data in total, but so far Varnish has downloaded 800GB from my file server. I'm using the default VCL file that comes with Varnish and the response headers for files served by the file server are similar to the following: HTTP/1.1 200 OK Cache-Control: max-age=290304000, public Content-Type: image/jpeg Expires: Wed, 29 Dec 2010 21:38:33 GMT Server: Microsoft-IIS/7.0 E-Tag: "8b4723296ab697530768f18b1378b269" Content-Disposition: inline; filename=image046.jpg; X-AspNet-Version: 4.0.30319 X-Powered-By: ASP.NET Date: Thu, 23 Dec 2010 05:38:33 GMT Content-Length: 100592 I'm starting varnishd with the following options: varnish/sbin/varnishd -a 0.0.0.0:80 -f varnish/etc/varnish/default.vcl -s file,varnish/var/lib/varnish/varnish_storage.bin,100G

• Groovy JUnit test support

  - by Martin Janicek

  Good news everyone! I've implemented support for the Groovy JUnit tests which basically means you can finally use Groovy in the area where is so highly productive! You can create a new Groovy JUnit test in the New File/Groovy/Groovy JUnit test and it should behave in the same way as for Java tests. Which means if there is no JUnit setup in your project yet, you can choose between JUnit 3 and JUnit 4 template and with respect to your choice the project settings will be changed (in case of the Maven based projects the correct dependencies and plugins are added to the pom.xml and in case of the Ant based project the JUnit dependency is configured). Or if the project is already configured, the correct template will be used. After that the test skeleton is created and you can write your own code and of course run the tests together with the java ones. Some of you were asking for this feature and of course I don't expect it will be perfect from the beginning so I would be really glad to see some constructive feedback about what could be improved and/or redesigned ;] ..at the end I have to say that the feature is not active for the Ant based Java EE projects yet (I'm aware of it and it will be fixed to the NetBeans 7.3 final - actually it will be done in a few days/weeks, just want you to know). But it's already complete in all types of the Maven based projects and also for the Ant based J2SE projects. And as always, the daily build where you can try the feature can be downloaded right here, so don't hesitate to try it!

• Is vSphere's Data Recover appliance 'production-ready'?

  - by Chopper3

  I have a smallish lab environment (16 x ESX4iU1 hosts and VC4U1) that I periodically want to backup. Normally in production we snap to secondary SAN boxes then have disk-based VTL backups via NetBackup which eventually migrate to off-site removable disks but this seems like an overkill for my own kit. I've spent a bit of time with vSphere's 'Data Recovery' appliance, it was easy enough to setup and I've not really ran into any issues with it but that doesn't mean I trust it fully. Have you had any experiences with it, positive or negative that would help me decide whether to trust it or pay Symantec for more licences? Thank you in advance.

• What emulator / VM software can I use to create a Win32-portable Linux Guest?

  - by Jotham

  Hi, I want to create a portable VM setup so that I can boot a Linux install regardless of which Windows XP / Windows 7 host machine I am on. I was looking at Qemu but it doesn't appear to have a relatively safe win32 build. Other things like VirtualBox require complete install on the host OS for performance reasons. I'm not so concerned about performance, I just want to run a few curses based applications. My ideal end goal would be a a memory stick of some size with a VM/Emulator I can boot on most WinXP/Windows 7 machines and access my own curses based applications (probably archlinux or debian). Any help would be appreciated. Regards,

• PHP Mail Relay via Remote smtp Server

  - by Toqeer

  We have a php application running on Linux which sends emails to there users. Currently its setup like php.ini is configured to send via local sendmail server but we have separate mail server for our organization for this domain. I want to send the php application emails via that remote smtp server so these emails can have the correct SPF records and sign via DKIM. But I could not see such option in php.ini to specify the remote host address to forward emails to that, its for windows only. I saw some post which suggest phpMailer but I could not find how to configure that so all our php application could send via our remote SMTP.

• How to install Ubuntu 12.04.1 in EFI mode with Encrypted LVM?

  - by g0lem

  I'm trying to properly install Ubuntu 12.04.1 LTS 64-bit PC (AMD64) with the alternate install CD ".iso" on a lenovo Thinkpad X220. Default Hard Disk (with a pre-installed version of Windows 7) has been replaced with a brand new SSD. The UEFI BIOS of the lenovo Thinkpad X220 is set to "UEFI Boot only" & "USB UEFI BIOS Support" is enabled (I'm using an external USB DVD reader to perform Ubuntu installation). The BIOS is a Phoenix SecureCore Tiano, BIOS version is 8DET56WW (1.26). The attempts below are made with the UEFI BIOS settings described above. Here's what I've tried so far: Boot on a live GParted CD Create a GPT partition table Create a FAT32 partition for UEFI System, set the partition to "EF00" type ("boot" flag) Leave remaining space unformated Boot on Ubuntu 12.04.1 LTS 64-bit PC (AMD64) with alternate CD: Perform the install with network updates enabled Use manual partitioning FAT32 partition created with GParted is used as "EFI System partition" Remaining space is set to be used as "Physical volume for LVM" Then "Configure encrypted volumes" using the previous "Physical volume for LVM" as the encrypted container, passphrase is setup. "Configure the Logical Volume Manager" creating a volume Group using the encrypted container /dev/mapper/sda2_crypt Creation of the Logical Volumes "Create logical volume", choosing the previously created volume Group Assign a mount point and file system to the Logical volumes : LV-root for / LV-var for /var LV-usr for /usr LV-usr-local for /usr/local LV-swap for swap LV-home for /home NOTE: /tmp would be in RAM only using TMPFS Bootloader step: neither my ESP partition (/dev/sda1, /dev/sda or MBR) seems to be the right place for GRUB, I get the following message (X suffix is for demonstration only): unable to install grub in /dev/sdaX Executing 'grub-install /dev/sdaX' failed This is a fatal error. Finish installation without the Bootloader & Reboot The system doesn't start, there's no EFI/GRUB menu at startup. What are the steps to perform a clean and working installation of Ubuntu 12.04.1 Precise Pangolin, 64bit version in U(EFI) mode using the encrypted LUKS + LVM scheme described above?

• Copy/move EBS volume from one Region to another

  - by Gnanam

  Background of our setup: We've hosted our web-based application in Amazon EC2 US East (Virginia) Region. Our instance is based on Linux distribution (CentOS) and AMI is S3-backed. 1 EBS volume (400 GB size) is attached to this instance. Question: We've planned to migrate our deployment to US West (N. California) Region. From AWS doc, I understood that for moving AMI, there is a command-line tool available - ec2-migrate-bundle. But for moving EBS volume across Region, currently there is no tool available. I'm looking for easiest and/or fastest way of copying/moving EBS volume from one Region to another. Also, are there any hidden risks involved during and/or after the migration? Experts ideas/suggestions/recommendations on this are highly appreciated.

• Can't ping self

  - by Paddy

  I have a wireless internet connection setup on my Mac. (v10.5.6) Am connected to the internet and everything is running smoothly. I recently discovered a quirky behaviour while setting up apache web server. When i typed in my dynamic ip (http://117.254.149.11/) in the webbrowser to visit my site pages it just timed out. In terminal i tried pinging localhost and it worked. $ ping localhost PING localhost (127.0.0.1): 56 data bytes 64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.063 ms 64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.056 ms 64 bytes from 127.0.0.1: icmp_seq=2 ttl=64 time=0.044 ms But if i pinged my ip it would just time out. $ ping 117.254.149.11 PING 117.254.149.11 (117.254.149.11): 56 data bytes ^C --- 117.254.149.11 ping statistics --- 10 packets transmitted, 0 packets received, 100% packet loss Pinging any other site works though.

• Joomla Secondary Users

  - by Gaz_Edge

  Background I have a joomla based application. My customers sign up and they register as a user on the site. My customers (primary customers) then have their own space on the site that they can then setup their own customers (secondary customer). Question/Problem The problem I am having is that I need to tag each secondary customer to a primary customer. I thought about just creating a new component and having a separate table that includes all the secondary customers. The problem is that I then lose out on all the authentication, session handling and login/logout that the core joomla _users component offers. I then thought about just having all the users in the core _users table and add the primary customer associated with each secondary customer to a field in a profile plugin. This would work for the most part, but this means that primary customers cannot create a secondary customer with a user name that already exists in the _users table. I didn't think this would be an issue, but several of my primary customers (currently only test users) have been confused by the site telling them a username is not available, since they can only see the names of their own secondary customers. Any ideas on some architectural changes I could make to solve this?

• The tale of how the PowerShell CmdLets got installed with Azure SDK 1.4

  - by Enrique Lima

  I installed the Azure SDK 1.4 while rebuilding my laptop and ran the installation for the Windows Azure Service Management PowerShell CmdLets. Kicked off the installation script for the WASM PowerShell CmdLets by locating the path to which WASM PowerShell CmdLets was deployed to. Double clicked the startHere command. It will then open the WASM installation dialog. Click Next. Click Next. Notice the red x next to the Azure SDK 1.3, the problem is I have SDK 1.4 Here is the workaround, I go back to the location of the deployed WASM sources. Go into the setup path, then scripts>dependencies>check. Now, locate the CheckAzureSDK.ps1 file, and right-click, then edit. This is the content in the ps1 file, it check for the specific version of the Azure SDK, in this case, it is looking for version 1.3.11133.0038. We need for it to check for version 1.4.20227.1419 Now, save your ps1 file, go back to the open WASM install dialog, and click rescan. This time it should pass, then click next. A Command prompt window will appear, click any key. This completes the installation, click Close.

• Perl script rendered in browser as code through symlink - fine when accessed directly

  - by John Dittmar

  I have a Rails 4 app that has some views that post to Perl cgi scripts. The perl scripts are accessed via a symbolic link to a folder called "cgi-bin". When I navigate to a perl script through the symbolic link they are rendered as text instead of executed (ie: localhost:3000/cgi-bin/test.cgi), however when I access them directly they execute without issue (ie. localhost/path/to/cgi-bin/test.cgi). I am using apache2 on os x. In the directory localhost/path/to/ I have an .htaccess file that contains the following: # General Apache options AddHandler fastcgi-script .fcgi AddHandler cgi-script .cgi Options +FollowSymLinks +ExecCGI I have the exact same lines in the .htaccess file that I have in localhost:3000/ I have also uncommented the AllowOverride all in httpd.conf. The are no errors in apache's error log. When I access the direct link to test.cgi a new line is appended to apache's access log, when I access the script through the symbolic link (and it is rendered as text), there is no line appended to the access log. Any idea why this error occurs? This setup worked fine in a previous version of rails of OS X, but recently I upgraded to Mavericks and figured I should update the Rails application to v4.0 as well.

• How to forward AIM to Gmail

  - by iamjames

  Still have an old AIM email address lying around and would like to forward it to Gmail?  Here's how: 1.  Login to your AIM and click on Settings on the far right 2.  In the left menu click IMAP and POP  3.  This shows you your IMAP and POP setup information for AIM.  We're going to put this into your Gmail account so your Gmail account will check your AIM account and download all AIM emails. 4.  Login to your Gmail, click Settings and click Accounts and Import 5.  Click "Import mail and contacts".  A new window will pop up asking what account you want to import.  Enter your AIM Email Address and click Continue 6.  The next page asks for your password.  Enter your password and click Continue.  Step 2 asks your Import options.  I'd put a checkmark in "Leave a copy of retrieved message on server".  That way all your mail is still stored on AIM if you ever need it. 7.  Click Start import and you're done.  Next screen says it make take several hours up to 2 days before you start seeing imported messages and can check the status at Settings > Accounts and Import

• Securing a persistent reverse SSH connection for management

  - by bVector

  I am deploying demo Ubuntu 10.04 LTS servers in environments I do not control and would like to have an easy and secure way to administer these machines without having to have the destination firewall forward port 22 for SSH access. I've found a few guides to do this with reverse port (e.g. howtoforge reverse ssh tunneling guide) but I'm concerned with security of the stored ssh credentials required for the tunnel to be opened automatically. If the machine is compromised (primary concern is physical access to the machine is out of my control) how can I stop someone from using the stored credentials to poke around in the reverse ssh tunnel target machine? Is it possible to secure this setup, or would you suggest an alternate method?

• How can I get my ATI / AMD drivers to work with any kernel above 3.2.0.x?

  - by TorakTu

  How can I get my ATI / AMD drivers to work with any kernel above 3.2.0.x ? WHAT DID WORK Installed original AMD64 version of Ubuntu 12.04 ISO image. Burned DVD and installed which shown kernel 3.2.0-23 to begin with. Got 5.1 surround sound working. Got ATI ( Now its AMD ) video drivers installed for my Radeon HD R6870 Video card from AMD's website. fglrxinfo came up and reported as normal. THE PROBLEM Kernel 3.2.0.x kept locking up so I tried higher kernel versions. But ATI / AMD Drivers do not install on any kernel Above 3.2.0.x WHAT I HAVE TRIED I have gone over this tutorial many times ( https://help.ubuntu.com/community/BinaryDriverHowto/ATI ) and it doesn't work on ANY kernel except 3.2.0.x. The problems I am having here are that the ATI / AMD drivers working for the 12.04 Precise with kernel 3.2.0-23 and 24, But the computer kept locking up. Although all my games would work, the lock ups were random and were constant. So I looked all over the web for 3 days trying to find an answer and the lock up issue was said to just update the kernel. So I did. Have tried many kernels. All of them .. no lock ups. BUT the Restricted AMD drivers from the AMD website will not install. And none of the OpenSource AMD drivers have EVER installed no matter what Kernel or version I tried. EXAMPLE OUTPUT OF 3D TYPE OF ERRORS Javax.media.opengl.GLException: glXGetConfig failed: error code GLX_NO_EXTENSION at com.sun.opengl.impl.x11.X11GLDrawableFactory.glXGetConfig(X11GLDrawableFactory.java:651) at com.sun.opengl.impl.x11.X11GLDrawableFactory.xvi2GLCapabilities(X11GLDrawableFactory.java:350) at com.sun.opengl.impl.x11.X11GLDrawableFactory.chooseGraphicsConfiguration(X11GLDrawableFactory.java:174) at javax.media.opengl.GLCanvas.chooseGraphicsConfiguration(GLCanvas.java:520) at javax.media.opengl.GLCanvas.<init>(GLCanvas.java:131) at haven.HavenPanel.<init>(HavenPanel.java:68) at haven.HavenPanel.<init>(HavenPanel.java:78) at haven.MainFrame.<init>(MainFrame.java:182) at haven.MainFrame.main2(MainFrame.java:306) at haven.MainFrame.access$100(MainFrame.java:34) at haven.MainFrame$7.run(MainFrame.java:360) at java.lang.Thread.run(Thread.java:722) And of course this is what fglrxinfo shows : X Error of failed request: BadRequest (invalid request code or no such operation) Major opcode of failed request: 139 (ATIFGLEXTENSION) Minor opcode of failed request: 66 () Serial number of failed request: 13 Current serial number in output stream: 13 EDIT : I forgot to mention that I DID look at this post over the last few days and it did not help.

• Windows 7 Line In Delay Issue

  - by CheeseConQueso

  Not sure if this question should be posted on a different stack exchange site, so if you find that it should not be posted here, please move it. Either way, if you know the solution, please advise. I'm running Windows 7 Pro 32-bit on my Dell Latitude 2100 netbook and I'm having an issue with the line in device/driver/functionality. The device & driver are stock: Driver Date: 7/13/2009 Driver Version: 6.1.7600.16385 I'm almost sure that the manufacturer of the sound card is RealTek. The problem is that there is a delay (when monitoring input) between the source and the speakers. My setup is bass guitar running through a 12' long instrument cable (1/4") with a 1/4" female to 1/8" male adapter into the line in port on the computer. Then the 15' long headphones/line out cable goes into a standard set of powered speakers. How do I get rid of this delay? Thanks for any help.

• File replication among EC2 instances

  - by Peuge

  I am pretty new to AWS so please excuse my ignorance. We are wanting to have a setup whereby we have a SQL DB instance + web server instance. However we would like the Web server to sit behind an ELB thus allowing us to use Autoscaling. My question however is how to we replicate the web app across instances? Say for example we have two web servers running and we need to make a critical update to the web app, ultimately we would only want to upload to one instance and not both. Is it even best practice to store your web app on the instance or are there better ways to store and share the app between instances?

• How do you manage updates without a staging environment: CentOS 6.3

  - by Gregg Leventhal

  I am managing about 20 servers, many of them virtual. They are almost all different purpose, and none are clustered. I have a distributed LAMP stack, a few application servers, some build servers, a few KVM hosts. They are CentOS 6.3 mostly with a few Ubuntu (unfortunately). I don't have the resources to setup a staging environment where I can have duplicates of my machines and test updates before rolling them out. I am taking file backups. What I want to know is how you are approaching backing up your Linux systems. I assume you don't just do yum update, but then how are you choosing the packages worthy of updating? When (if ever) are you updating the kernel, etc.. How do you test updates without a staging environment? Snapshot and hope for the best?

• Unable to install Android for Windows 7 because JDK is not found

  - by user1294663

  I have JDK SE7u4 installed in windows 7. I tried to install Android on Windows 7 using the installer_r18-windows.exe but no avail. The setup window showed the message saying that the Java SE JDK not found and ERROR: Failed to find Java version for C:\Windows\System32\java.exe The system cannot found the file specified. If you believe you have a JDK installed and it was not properly recognized, simply set an environment variable JAVA_HOME to point to it I right clicked on Computer Properties Advanced System Settings Environment variables. I created a NEW system variable called JAVA_HOME and set the value as C:\Program Files\Java\jdk1.7.0_04\bin or C:\Windows\System32\java.exe. I ran the installer again — the same error message still appeared.

• How to get Wifi Working Properly - I am Noob

  - by user287853

  I'm a noob to Ubuntu, but not computers. I installed a full version of Ubuntu version 12 whatever it is. I run it on a machine that has Win7/Win8 on another hard drive. My wireless adapter is some tiny USB stick I got on eBay - it works great in Windows, but I can't get it to work in Ubuntu. More precisely, Ubuntu is providing me a list (sometimes) of wireless networks in the area and when I try to connect to mine it just keeps password prompting me even though the one I use is correct. I looked over all the settings multiple times and don't believe there is anything in error regarding what it takes to connect to my network. So, I thought maybe it is a driver issue and came across NDIS. I thought I should try installing it, but I don't know how when I can't connect the Ubuntu machine to the Internet. I tried some commands to no avail. I have the Ubuntu installation disc and it shows a NDIS common and utils .deb files in there. Can someone out there help me out to get this wireless setup so I can get online?

• Obtaining the correct Client IP address when a Physical Load Balancer and a Web Server Configured With Proxy Plug-in Are Between The Client And Weblogic

  - by adejuanc

  Some Load Balancers like Big-IP have build in interoperability with Weblogic Cluster, this means they know how Weblogic understand a header named 'WL-Proxy-Client-IP' to identify the original client ip.The problem comes when you have a Web Server configured with weblogic plug-in between the Load Balancer and the back-end weblogic servers - WL-Proxy-Client-IP this is not designed to go to Web server proxy plug-in. The plug-in will not use a WL-Proxy-Client-IP header that came in from the previous hop (which is this case is the Physical Load Balancer but could be anything), in order to prevent IP spoofing, therefore the plug-in won't pass on what Load Balancer has set for it.So unfortunately under this Architecture the header will be useless. To get the client IP from Weblogic you need to configure extended log format and create a custom field that gets the appropriate header containing the IP of the client.On WLS versions prior to 10.3.3 use these instructions:You can also create user-defined fields for inclusion in an HTTP access log file that uses the extended log format. To create a custom field you identify the field in the ELF log file using the Fields directive and then you create a matching Java class that generates the desired output. You can create a separate Java class for each field, or the Java class can output multiple fields. For a sample of the Java source for such a class, seeJava Class for Creating a Custom ELF Field to import weblogic.servlet.logging.CustomELFLogger;import weblogic.servlet.logging.FormatStringBuffer;import weblogic.servlet.logging.HttpAccountingInfo;/* This example outputs the X-Forwarded-For field into a custom field called MyOriginalClientIPField */public class MyOriginalClientIPField implements CustomELFLogger{ public void logField(HttpAccountingInfo metrics,  FormatStringBuffer buff) {   buff.appendValueOrDash(metrics.getHeader("X-Forwarded-For");  }}In this case we are using 'X-Forwarded-For' but it could be changed for the header that contains the data you need to use.Compile the class, jar it, and prepend it to the classpath.In order to compile and package the class: 1. Navigate to <WLS_HOME>/user_projects/domains/<SOME_DOMAIN>/bin2. Set up an environment by executing: $ . ./setDomainEnv.sh This will include weblogic.jar into classpath, in order to use any of the libraries included under package weblogic.*3. Compile the class by copying the content of the code above and naming the file as:MyOriginalClientIPField.java4. Run javac to compile the class.$javac MyOriginalClientIPField.java5. Package the compiled class into a jar file by executing:$jar cvf0 MyOriginalClientIPField.jar MyOriginalClientIPField.classExpected output is:added manifestadding: MyOriginalClientIPField.class(in = 711) (out= 711)(stored 0%)6. This will produce a file called:MyOriginalClientIPField.jar This way you will be able to get the real client IP when the request is passing through a Load Balancer and a Web server before reaching WLS. Since 10.3.3 it is possible to configure a specific header that WLS will check when getRemoteAddr is called. That can be set on the WebServer Mbean. In this case, set that to be X-Forwarded-For header coming from Load Balancer as well.

• Antenna Aligner Part 6: Little Robots

  - by Chris George

  A week ago I took temporary ownership of a HTC Desire S so that I could start testing my app under Android. Support for Android was not in my original plan, but when Nomad added support for it recently, I starting thinking why not! So with some trepidation, I clicked the Build for Android button on the Nomad toolbar... nothing. Hmm... that's not right, I was expecting something to build. After a bit of faffing around I finally realised that I hadn't read the text on the Android setup page properly (yes that's right, RTFM!), and I needed a two-part application identifier, separated by a dot. I did this (not sure what the two part thing is all about, that one my list to investigate!) After making the change, the Android build worked and created the apk file. I uploaded this to the device and nervously ran it... it worked!!!  Well, more or less! So, there was not splash screen, but this was no surprise because I only have the iOS icons and splash screen in my project at the moment. What was more concerning was the compass update didn't seem to be working. I suspect this is a result of using an iOS specific option in the Phonegap compass watcher. Another thing to investigate. I've also just noticed that the css gradient background hasn't worked either... These issues aside, it was actually more successful than I was expecting, so happy days! Right, lets get Googling...   Next time: Preparing for submission to the App Store! :-)

• Running CORN job on Ubuntu server for SugarCRM

  - by Logik

  i am pretty inexperienced in Linux.So be descriptive on your answer. My environment :Local Linux server 12.04 hosting Sugar CRM 6.5.2. There is area in sugar CRM called scheduler. I can configured some predefined jobs here. in my case i am trying to run email reminders (ever min/hour/day/month). For this scheduler to be effective, i read some where i need to setup CRON job. So i did some research & finally put following lines in CRONTAB for the root user, as per instructions given in sugarCRM. cd /var/www/crm; php -f cron.php /dev/null 2&1 Well i am creating contracts in my sugarCRM (AOS module) & i want email reminders to be sent for these contracts to the concern person. Now my sugarCRM email is configured correctly & i can send test emails using it. But the CRON + scheduler not giving any result. I can't receive any emails. Then i tried to read /var/log/syslog & it is showing entry for following line each minute. Oct 27 15:03:01 unicomm CRON[28182]: (root) CMD (cd /var/www/crm; php -f cron.php /dev/null 2&1) I've few questions: 1) what does the CRON job line i've added in crontab mean? cd /var/www/crm; php -f cron.php /dev/null 2&1 is not making any sense to me. 2) How am i suppose to get this thing work? I've searched a lot (including SugarCRM forum), but no luck.

• design for supporting entities with images

  - by brainydexter

  I have multiple entities like Hotels, Destination Cities etc which can contain images. The way I have my system setup right now is, I think of all the images belonging to this universal set (a table in the DB contains filePaths to all the images). When I have to add an image to an entity, I see if the entity exists in this universal set of images. If it exists, attach the reference to this image, else create a new image. E.g.: class ImageEntityHibernateDAO { public void addImageToEntity(IContainImage entity, String filePath, String title, String altText) { ImageEntity image = this.getImage(filePath); if (image == null) image = new ImageEntity(filePath, title, altText); getSession().beginTransaction(); entity.getImages().add(image); getSession().getTransaction().commit(); } } My question is: Earlier I had to write this code for each entity (and each entity would have a Set collection). So, instead of re-writing the same code, I created the following interface: public interface IContainImage { Set<ImageEntity> getImages(); } Entities which have image collections also implements IContainImage interface. Now, for any entity that needs to support adding Image functionality, all I have to invoke from the DAO looks something like this: // in DestinationDAO::addImageToDestination { imageDao.addImageToEntity(destination, imageFileName, imageTitle, imageAltText); // in HotelDAO::addImageToHotel { imageDao.addImageToEntity(hotel, imageFileName, imageTitle, imageAltText); It'd be great help if someone can provide me some critique on this design ? Are there any serious flaws that I'm not seeing right away ?
