• how to check if something is in the queue of torque?

  - by kloop

  I want to re-run some jobs that completed prematurely under torque. These jobs are run through .job scripts (using qsub). However, I don't want to re-run a job which is already in the queue. Given a script filename, how can I know whether it is already in torque's queue (using qstat?) or not? I prefer to do it programmatically, of course, so any oneliner that searches for a given script name would be great. I will note that I can grep submit_args in qstat -f, but I can't get it to display the whole script name when it is too long. This is crucial. EDIT: I managed to solve it using the following command: qstat -x | perl -pi -e 's/\<\//\n/g' | grep job$ | grep -v submit_args | perl -pi -e 's/Job_Id\>\<Job_Name\>//' works because all my scripts end in the string "job".

• Is there a way to import a scheduled task from windows 2003 (.job) to windows 2008 (.xml) ?

  - by Rodrigo

  I had some jobs to be moved from the old production server (windows 2003 server standard) to the new machine (windows 2008 server standard), but the new server is unable to read the old .job format, also the import wizard only imports from .xml job files (same version). Obviously I don't want to rebuild all the jobs by hand, but can't find a tool that makes the process a very little easier. I don't trust in Microsoft for this kind of tools, my previously experiences had been to bad (DTS - SSIS). Any ideas? Thanks in advance.

• Quartz Thread Execution Parallel or Sequential?

  - by vikas

  We have a quartz based scheduler application which runs about 1000 jobs per minute which are evenly distributed across seconds of each minute i.e. about 16-17 jobs per second. Ideally, these 16-17 jobs should fire at same time, however our first statement, which simply logs the time of execution, of execute method of the job is being called very late. e.g. let us assume we have 1000 jobs scheduled per minute from 05:00 to 05:04. So, ideally the job which is scheduled at 05:03:50 should have logged the first statement of the execute method at 05:03:50, however, it is doing it at about 05:06:38. I have tracked down the time taken by the scheduled job which comes around 15-20 milliseconds. This scheduled job is fast enough because we just send a message on an ActiveMQ queue. We have specified the number of threads of quartz to be 100 and even tried with increasing it to 200 and more, but no gain. One more thing we noticed is that logs from scheduler are coming sequential after first 1 minute i.e. [Quartz_Worker_28] <Some log statement> .. .. [Quartz_Worker_29] <Some log statement> .. .. [Quartz_Worker_30] <Some log statement> .. .. So it suggesting that after some time quartz is running threads almost sequential. May be this is happening due to the time taken in notifying the job completion to persistence store (which is a separate postgres database in this case) and/or context switching. What can be the reason behind this strange behavior? EDIT: More detailed Log [06/07/12 10:08:37:192][QuartzScheduler_Worker-34][INFO] org.quartz.plugins.history.LoggingTriggerHistoryPlugin - Trigger [<trigger_name>] fired job [<job_name>] scheduled at: 06-07-2012 10:08:33.458, next scheduled at: 06-07-2012 10:34:53.000 [06/07/12 10:08:37:192][QuartzScheduler_Worker-34][INFO] <my_package>.scheduler.quartz.ScheduledLocateJob - execute begin--------- ScheduledLocateJob with key: <job_name> started at Fri Jul 06 10:08:37 EDT 2012 [06/07/12 10:08:37:192][QuartzScheduler_Worker-34][INFO] <my_package>.scheduler.quartz.ScheduledLocateJob <some log statement> [06/07/12 10:08:37:192][QuartzScheduler_Worker-34][INFO] <my_package>.scheduler.quartz.ScheduledLocateJob <some log statement> [06/07/12 10:08:37:192][QuartzScheduler_Worker-34][INFO] <my_package>.scheduler.quartz.ScheduledLocateJob <some log statement> [06/07/12 10:08:37:220][QuartzScheduler_Worker-34][INFO] <my_package>.scheduler.quartz.ScheduledLocateJob - execute end--------- ScheduledLocateJob with key: <job_name> ended at Fri Jul 06 10:08:37 EDT 2012 [06/07/12 10:08:37:220][QuartzScheduler_Worker-34][INFO] org.quartz.plugins.history.LoggingTriggerHistoryPlugin - Trigger [<trigger_name>] completed firing job [<job_name>] with resulting trigger instruction code: DO NOTHING.

Shouldn't it be a misfire?

• MVC keeping the PartialView in its own context - ignore the main view holding the partial view

  - by Mike

  I'm looking at the partialview components of the MVC Framework. i want my partial view to be handled in its own action and for the rest of the view to handle itself, but i'm getting an exception because the main page is not getting its view fired. Am i going around this the wrong way? My Main View (Jobs/Index.aspx): <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MvcApplication3.Models.JobViewModel>" %> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <% Html.RenderPartial("JobListing", Model.Jobs); %> </asp:Content> The partialview (Jobs/JobListing.ascx): <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<List<MvcApplication3.Models.Job>>" %> <table> <tr> <td> Job Title </td> <td> Job Location</td> </tr> <% foreach (var job in Model) { %> <tr> <td> <%= job.Title %> </td> <td> <%= job.Location %> </td> </tr> <% } %> <% Html.BeginForm("DoSomeStuff", "Job", null, FormMethod.Post); %> <%= Html.TextBox("SomeInfo") %> <button type="submit" id="submit" /> <% Html.EndForm(); %> The main controller for both the main view (Index) and the partialview (DoSomeStuff()) public class JobController : Controller { public ActionResult Index() { JobProvider provider = new JobProvider(Session); JobViewModel vm = new JobViewModel(); vm.Jobs = provider.GetJobs(); return View(vm); } public PartialViewResult DoSomeStuff() { return PartialView("JobListing"); } } As you can see in the partial view, it has its own form that posts to the Action called DoSomeStuff(). i want this action to handle any data submitted from that form. but when the form is submitted the main action (Index) does not fire and then i get an exception as the Model (.Models.JobViewModel) is not passed to the view that the partialview (JobListings) lives in. basically what im saying is, if i have a myview.aspx with lots of html.RenderPartialView('apartialview') that have forms in them, can i get it so these forms post to their own actions and the main view (with what ever model it inherits) is handled as well. Rather then having all the form submitting code in the main action for the view. am i do this wrong?

• Azure Grid Computing - Worker Roles as HPC Compute Nodes

  - by JoshReuben

  Overview ·        With HPC 2008 R2 SP1 You can add Azure worker roles as compute nodes in a local Windows HPC Server cluster. ·        The subscription for Windows Azure like any other Azure Service - charged for the time that the role instances are available, as well as for the compute and storage services that are used on the nodes. ·        Win-Win ? - Azure charges the computer hour cost (according to vm size) amortized over a month – so you save on purchasing compute node hardware. Microsoft wins because you need to purchase HPC to have a local head node for managing this compute cluster grid distributed in the cloud. ·        Blob storage is used to hold input & output files of each job. I can see how Parametric Sweep HPC jobs can be supported (where the same job is run multiple times on each node against different input units), but not MPI.NET (where different HPC Job instances function as coordinated agents and conduct master-slave inter-process communication), unless Azure is somehow tunneling MPI communication through inter-WorkerRole Azure Queues. ·        this is not the end of the story for Azure Grid Computing. If MS requires you to purchase a local HPC license (and administrate it), what's to stop a 3rd party from doing this and encapsulating exposing HPC WCF Broker Service to you for managing compute nodes? If MS doesn’t  provide head node as a service, someone else will! Process ·        requires creation of a worker node template that specifies a connection to an existing subscription for Windows Azure + an availability policy for the worker nodes. ·        After worker nodes are added to the cluster, you can start them, which provisions the Windows Azure role instances, and then bring them online to run HPC cluster jobs. ·        A Windows Azure worker role instance runs a HPC compatible Azure guest operating system which runs on the VMs that host your service. The guest operating system is updated monthly. You can choose to upgrade the guest OS for your service automatically each time an update is released - All role instances defined by your service will run on the guest operating system version that you specify. see Windows Azure Guest OS Releases and SDK Compatibility Matrix (http://go.microsoft.com/fwlink/?LinkId=190549). ·        use the hpcpack command to upload file packages and install files to run on the worker nodes. see hpcpack (http://go.microsoft.com/fwlink/?LinkID=205514). Requirements ·        assuming you have an azure subscription account and the HPC head node installed and configured. ·        Install HPC Pack 2008 R2 SP 1 -  see Microsoft HPC Pack 2008 R2 Service Pack 1 Release Notes (http://go.microsoft.com/fwlink/?LinkID=202812). ·        Configure the head node to connect to the Internet - connectivity is provided by the connection of the head node to the enterprise network. You may need to configure a proxy client on the head node. Any cluster network topology (1-5) is supported). ·        Configure the firewall - allow outbound TCP traffic on the following ports: 80,       443, 5901, 5902, 7998, 7999 ·        Note: HPC Server  uses Admin Mode (Elevated Privileges) in Windows Azure to give the service administrator of the subscription the necessary privileges to initialize HPC cluster services on the worker nodes. ·        Obtain a Windows Azure subscription certificate - the Windows Azure subscription must be configured with a public subscription (API) certificate -a valid X.509 certificate with a key size of at least 2048 bits. Generate a self-sign certificate & upload a .cer file to the Windows Azure Portal Account page > Manage my API Certificates link. see Using the Windows Azure Service Management API (http://go.microsoft.com/fwlink/?LinkId=205526). ·        import the certificate with an associated private key on the HPC cluster head node - into the trusted root store of the local computer account. Obtain Windows Azure Connection Information for HPC Server ·        required for each worker node template ·        copy from azure portal - Get from: navigation pane > Hosted Services > Storage Accounts & CDN ·        Subscription ID - a 32-char hex string in the form xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx. In Properties pane. ·        Subscription certificate thumbprint - a 40-char hex string (you need to remove spaces). In Management Certificates > Properties pane. ·        Service name - the value of <ServiceName> configured in the public URL of the service (http://<ServiceName>.cloudapp.net). In Hosted Services > Properties pane. ·        Blob Storage account name - the value of <StorageAccountName> configured in the public URL of the account (http://<StorageAccountName>.blob.core.windows.net). In Storage Accounts > Properties pane. Import the Azure Subscription Certificate on the HPC Head Node ·        enable the services for Windows HPC Server  to authenticate properly with the Windows Azure subscription. ·        use the Certificates MMC snap-in to import the certificate to the Trusted Root Certification Authorities store of the local computer account. The certificate must be in PFX format (.pfx or .p12 file) with a private key that is protected by a password. ·        see Certificates (http://go.microsoft.com/fwlink/?LinkId=163918). ·        To open the certificates snapin: Run > mmc. File > Add/Remove Snap-in > certificates > Computer account > Local Computer ·        To import the certificate via wizard - Certificates > Trusted Root Certification Authorities > Certificates > All Tasks > Import ·        After the certificate is imported, it appears in the details pane in the Certificates snap-in. You can open the certificate to check its status. Configure a Proxy Client on the HPC Head Node ·        the following Windows HPC Server services must be able to communicate over the Internet (through the firewall) with the services for Windows Azure: HPCManagement, HPCScheduler, HPCBrokerWorker. ·        Create a Windows Azure Worker Node Template ·        Edit HPC node templates in HPC Node Template Editor. ·        Specify: 1) Windows Azure subscription connection info (unique service name) for adding a set of worker nodes to the cluster + 2)worker node availability policy – rules for deploying / removing worker role instances in Windows Azure o   HPC Cluster Manager > Configuration > Navigation Pane > Node Templates > Actions pane > New à Create Node Template Wizard or Edit à Node Template Editor o   Choose Node Template Type page - Windows Azure worker node template o   Specify Template Name page – template name & description o   Provide Connection Information page – Azure Subscription ID (text) & Subscription certificate (browse) o   Provide Service Information page - Azure service name + blob storage account name (optionally click Retrieve Connection Information to get list of available from azure – possible LRT). o   Configure Azure Availability Policy page - how Windows Azure worker nodes start / stop (online / offline the worker role instance -  add / remove) – manual / automatic o   for automatic - In the Configure Windows Azure Worker Availability Policy dialog -select days and hours for worker nodes to start / stop. ·        To validate the Windows Azure connection information, on the template's Connection Information tab > Validate connection information. ·        You can upload a file package to the storage account that is specified in the template - eg upload application or service files that will run on the worker nodes. see hpcpack (http://go.microsoft.com/fwlink/?LinkID=205514). Add Azure Worker Nodes to the HPC Cluster ·        Use the Add Node Wizard – specify: 1) the worker node template, 2) The number of worker nodes   (within the quota of role instances in the azure subscription), and 3)           The VM size of the worker nodes : ExtraSmall, Small, Medium, Large, or ExtraLarge.  ·        to add worker nodes of different sizes, must run the Add Node Wizard separately for each size. ·        All worker nodes that are added to the cluster by using a specific worker node template define a set of worker nodes that will be deployed and managed together in Windows Azure when you start the nodes. This includes worker nodes that you add later by using the worker node template and, if you choose, worker nodes of different sizes. You cannot start, stop, or delete individual worker nodes. ·        To add Windows Azure worker nodes o   In HPC Cluster Manager: Node Management > Actions pane > Add Node à Add Node Wizard o   Select Deployment Method page - Add Azure Worker nodes o   Specify New Nodes page - select a worker node template, specify the number and size of the worker nodes ·        After you add worker nodes to the cluster, they are in the Not-Deployed state, and they have a health state of Unapproved. Before you can use the worker nodes to run jobs, you must start them and then bring them online. ·        Worker nodes are numbered consecutively in a naming series that begins with the root name AzureCN – this is non-configurable. Deploying Windows Azure Worker Nodes ·        To deploy the role instances in Windows Azure - start the worker nodes added to the HPC cluster and bring the nodes online so that they are available to run cluster jobs. This can be configured in the HPC Azure Worker Node Template – Azure Availability Policy -  to be automatic or manual. ·        The Start, Stop, and Delete actions take place on the set of worker nodes that are configured by a specific worker node template. You cannot perform one of these actions on a single worker node in a set. You also cannot perform a single action on two sets of worker nodes (specified by two different worker node templates). ·        ·          Starting a set of worker nodes deploys a set of worker role instances in Windows Azure, which can take some time to complete, depending on the number of worker nodes and the performance of Windows Azure. ·        To start worker nodes manually and bring them online o   In HPC Node Management > Navigation Pane > Nodes > List / Heat Map view - select one or more worker nodes. o   Actions pane > Start – in the Start Azure Worker Nodes dialog, select a node template. o   the state of the worker nodes changes from Not Deployed to track the provisioning progress – worker node Details Pane > Provisioning Log tab. o   If there were errors during the provisioning of one or more worker nodes, the state of those nodes is set to Unknown and the node health is set to Unapproved. To determine the reason for the failure, review the provisioning logs for the nodes. o   After a worker node starts successfully, the node state changes to Offline. To bring the nodes online, select the nodes that are in the Offline state > Bring Online. ·        Troubleshooting o   check node template. o   use telnet to test connectivity: telnet <ServiceName>.cloudapp.net 7999 o   check node status - Deployment status information appears in the service account information in the Windows Azure Portal - HPC queries this -  see  node status information for any failed nodes in HPC Node Management. ·        When role instances are deployed, file packages that were previously uploaded to the storage account using the hpcpack command are automatically installed. You can also upload file packages to storage after the worker nodes are started, and then manually install them on the worker nodes. see hpcpack (http://go.microsoft.com/fwlink/?LinkID=205514). ·        to remove a set of role instances in Windows Azure - stop the nodes by using HPC Cluster Manager (apply the Stop action). This deletes the role instances from the service and changes the state of the worker nodes in the HPC cluster to Not Deployed. ·        Each time that you start a set of worker nodes, two proxy role instances (size Small) are configured in Windows Azure to facilitate communication between HPC Cluster Manager and the worker nodes. The proxy role instances are not listed in HPC Cluster Manager after the worker nodes are added. However, the instances appear in the Windows Azure Portal. The proxy role instances incur charges in Windows Azure along with the worker node instances, and they count toward the quota of role instances in the subscription.

• Fixing my SQL Directory NTFS ACLS

  - by Shawn Cicoria

  I run my development server by boot to VHD (Windows Server 2008 R2 x64).  In that instance, I also have an attached VHD (I attach via script at boot up time using Task Scheduler).  That VHD I have my SQL instances installed. So, the other day, acting hasty, I chmod my ACLS – wow, what a day after that. So, in order to fix it I created this set of BAT commands that resets it back to operational state – not 100% of all what you get, I also didn’t want to run a “repair” – but, all operational again. setlocal SET Inst100Path=H:\Program Files\Microsoft SQL Server\100 REM GOTO SQLE SET InstanceName=MSSQLSERVER SET InstIdPath=H:\Program Files\Microsoft SQL Server\MSSQL10.%InstanceName% SET Group=SQLServerMSSQLUser$SCICORIA-HV1$%InstanceName% SET AgentGroup=SQLServerSQLAgentUser$SCICORIA-HV1$%InstanceName% ICACLS "%InstIdPath%\MSSQL" /T /Q /grant "%Group%":(OI)(CI)FX ICACLS "%InstIdPath%\MSSQL\backup" /T /Q /grant "%Group%":(OI)(CI)F ICACLS "%InstIdPath%\MSSQL\data" /T /Q /grant "%Group%":(OI)(CI)F ICACLS "%InstIdPath%\MSSQL\FTdata" /T /Q /grant "%Group%":(OI)(CI)F ICACLS "%InstIdPath%\MSSQL\Jobs" /T /Q /grant "%Group%":(OI)(CI)F ICACLS "%InstIdPath%\MSSQL\binn" /T /Q /grant "%Group%":(OI)(CI)RX ICACLS "%InstIdPath%\MSSQL\Log" /T /Q /grant "%Group%":(OI)(CI)F ICACLS "%Inst100Path%" /T /Q /grant "%Group%":(OI)(CI)RX ICACLS "%Inst100Path%\shared\Errordumps" /T /Q /grant "%Group%":(OI)(CI)RXW ICACLS "%InstIdPath%\MSSQL" /T /Q /grant "%AgentGroup%":(OI)(CI)RX ICACLS "%InstIdPath%\MSSQL\binn" /T /Q /grant "%AgentGroup%":(OI)(CI)F ICACLS "%InstIdPath%\MSSQL\Log" /T /Q /grant "%AgentGroup%":(OI)(CI)F ICACLS "%Inst100Path%" /T /Q /grant "%AgentGroup%":(OI)(CI)RX REM THIS IS THE SQL EXPRESS INSTANCE :SQLE SET InstanceName=SQLEXPRESS SET InstIdPath=H:\Program Files\Microsoft SQL Server\MSSQL10.%InstanceName% SET Group=SQLServerMSSQLUser$SCICORIA-HV1$%InstanceName% SET AgentGroup=SQLServerSQLAgentUser$SCICORIA-HV1$%InstanceName% ICACLS "%InstIdPath%\MSSQL" /T /Q /grant "%Group%":(OI)(CI)FX ICACLS "%InstIdPath%\MSSQL\backup" /T /Q /grant "%Group%":(OI)(CI)F ICACLS "%InstIdPath%\MSSQL\data" /T /Q /grant "%Group%":(OI)(CI)F ICACLS "%InstIdPath%\MSSQL\FTdata" /T /Q /grant "%Group%":(OI)(CI)F ICACLS "%InstIdPath%\MSSQL\Jobs" /T /Q /grant "%Group%":(OI)(CI)F ICACLS "%InstIdPath%\MSSQL\binn" /T /Q /grant "%Group%":(OI)(CI)RX ICACLS "%InstIdPath%\MSSQL\Log" /T /Q /grant "%Group%":(OI)(CI)F ICACLS "%Inst100Path%" /T /Q /grant "%Group%":(OI)(CI)RX ICACLS "%Inst100Path%\shared\Errordumps" /T /Q /grant "%Group%":(OI)(CI)RXW ICACLS "%InstIdPath%\MSSQL" /T /Q /grant "%AgentGroup%":(OI)(CI)RX ICACLS "%InstIdPath%\MSSQL\binn" /T /Q /grant "%AgentGroup%":(OI)(CI)F ICACLS "%InstIdPath%\MSSQL\Log" /T /Q /grant "%AgentGroup%":(OI)(CI)F ICACLS "%Inst100Path%" /T /Q /grant "%AgentGroup%":(OI)(CI)RX endlocal

• Ruby but not Rails on my Resume

  - by Ken Bloom

  I have listed Ruby as a skill on my resume becuase I've been programming in Ruby for 5 years while I work on my Ph.D. thesis. I've mostly been using it to implement natural language processing algorithms. I'm starting to look for a job, and I posted my resume to a few sites (as an extra bonus when applying to certain on-target jobs). Now I get recruiters calling me to offer me Ruby on Rails jobs. The problem is that I've never learned Rails. It was never relevant to what I'm doing for my Ph.D. How do you recommend handling this situation to avoid wasting my time and theirs? (And learning Rails probably isn't an option until I finish my thesis.) Can my resume be adjusted to make this clearer? Should it be adjusted? Should I just politely tell them on the phone that I don't know Rails? By the way, the relevant part of my resume simply says: Skills: Programming Languages: C, C++, Java, Scala, Ruby, LaTeX Databases: MySQL, XML, XPath and lists a few other skill areas that couldn't possibly be confused with a Rails developer.

• How could this diagram for "making a career move into software development" be improved?

  - by Edward Tanguay

  I'm giving a talk in April 2011 on "Developer English" and showing my non-developer audience, mostly English teachers, various diagrams to explain how developers see their industry etc. One of these diagrams is "Hot Technologies", basically, if you want to become a developer, what technologies should you learn to have the highest chance of (1) getting a job (2) making a good salary, and (3) work with the most exciting technology. This is a draft I made just to get some ideas out, basically C#, PHP, Java are where the bulk of the jobs are. Mobile development has a big future. JavaScript is becoming more and more important, and I want to list "minor technologies" such a Python, Ruby on Rails to the side, I assume e.g. that in general, there are a much smaller percentage of jobs in these technologies as in C#, PHP, Java. How could this diagram be improved? UPDATE Thanks everyone for your suggestions. I included most of them in my updated graphic. Does anyone know of more Java technologies that would be appropriate here and could anything be added to the gaming technologies?

• Knowledge Transfer without a Plan

  - by Kanini

  Hello...We are doing work for a particular client managing their CRM implementation. (The CRM itself is a product which has been largely customized to suit my client's needs). Now, they want us to manage the Oracle batch jobs/ETL as well. And for this, they are ready to provide us with Knowledge Transfer. (The Oracle batch jobs/ETL is managed in-house by the client now). After much persuasion, I got one of the Project Lead (designation-wise) to email the client asking for a KT Plan. (The Project Lead kept saying that they have never had KT plans before and all that for which I offered I will draft a template and even that was rejected!). Email from us to them - Can you please share with us the KT Plan? Response from them - Not sure what is expected from my side? The KT is planned for tomorrow from 11 am onwards where Functional knowledge of existing ETL Data migration package will be shared. How do you handle such a client? Most likely what is going to happen is this. The person who is giving the KT will say that I have given complete Knowledge Transfer and we will go back and say that "No, this was not covered. For this, they provided an overview alone and left it at that!" and so on... My Project Lead also did not respond to that email. He just said that the meeting is scheduled to happen at 11 AM (basically repeating whatever the email said and left for the day!). What could I possibly do? PS: Look for another job is a very helpful answer, but I am not looking for it. :-)

• Newbie seeking advice on programming in general

  - by user974685

  need some of you to remember back to a time when you might have been bad at programming... Been at my new job (as a software developer) for a couple of months now, passed probation period. Have very little programming experience (C++ only) and am currently working with asp.net MVC and silverlight. So there's a website the company has been working on and I am joining the effort to make it better, iron out bugs etc. The problem is - learning about a system/website which has already been made, via visual studio. I ALWAYS feel HUGELY overwhelmed, never knowing which part of this line should I look up, and generally having lots of trouble getting the big picture. Visual studio itself is something I'm finding it difficult to get to grips with, let alone the asp.net framework. I get the impression that because my coworkers have more experience than me, they are getting all the good jobs, and I am left with crap to do - stuff which is not even vaguely programming. Meaning they are learning/creating more, and I am learning/creating near nothing. I'm getting demoralised, and too scared to say anything. I'm not stupid, I've read and practiced plenty of the fundamental programming concepts...I'm just bloody scared of this damn framework. I look at it and just feel paralyzed. The result is that I keep asking the older veteran guy of questions, and he is getting irritated, and would rather give me easy/mindless/non programming jobs to avoid wasting time with helping me out. Then when I don't understand something, I'm hesitating about whether or not I should ask him yet, and trying to decide if it would be a waste of time. I'm the kind of person who picks things up slowly, but with a lot of attention to detail. The former I think is making me look incompetent though. Anyone get where I'm coming from please say something helpful....I'm scared of losing my job in a few months or something...

• Exclusive use of a Jini server during long-running call

  - by Matthew Flint

  I'm trying to use Jini, in a "Masters/Workers" arrangement, but the Worker jobs may be long running. In addition, each worker needs to have exclusive access to a singleton resource on that machine. As it stands, if a Worker receives another request while a previous request is running, then the new request is accepted and executed in a second thread. Are there any best-practices to ensure that a Worker accepts no further jobs until the current job is complete? Things I've considered: synchronize the job on the server, with a lock on the singleton resource. This would work, but is far from ideal. A call from a Master would block until the current Worker thread completes, even if other Workers become free in the meantime unregister the Worker from the registry while the job is running, then re-register when it completes. Might work OK, but something doesn't smell right with this idea... Of course, I'm quite happy to be told that there are more appropriate technologies than Jini... but I wouldn't want anything too heavyweight, like rolling out EJB containers all over the place.

  - by Rohit Gupta

  If you facing the issue that the web Analytics Reports in SharePoint 2010 Central Administration is not updating data. When you go to your site > site settings > Site Web Analytics reports or Site Collection Analytics reports  You get old data as in the ribbon displayed "Data Last Updated: 12/13/2010 2:00:20 AM" Please insure that the following things are covered: Insure that Usage and Data Health Data Collection service is configured correctly. Log Collection Schedule is configured correctly Microsoft Sharepoint Foundation Usage Data Import and Microsoft SharePoint Foundation Usage Data Processing Timer jobs are configured to run at regular intervals One last important Timer job is the Web Analytics Trigger Workflows Timer Job insure that this timer job is enabled and scheduled to run at regular intervals (for each site that you need analytics for). After you have insured that the web analytics service configuration is working fine and the Usage Data Import job is importing the *.usage files from the ULS LOGS folder into the WSS_Logging database, and that all the required timer jobs are running as expected… wait for a day for the report to get updated… the report gets updated automatically at 2:00 am in the morning… and i could not find a way to control the schedule for this report update job. So be sure to wait for a day before giving up :)

• How do I prevent my filesystems from being mounted read-only after suspending?

  - by Chas. Owens

  I have Ubuntu 12.04 installed on an SDHC card (only one ext2 partition, no swap). When I suspend using pm-suspend, my root filesystem is mounted read-only. I am currently "fixing" this with the following file: /etc/pm/sleep.d/99_make_disk_rw: #!/bin/sh mount -o remount,rw / But the disk is marked as needing an fsck on reboot. How can I prevent the filesystem from being mounted read-only or whatever is going wrong here. Update: It looks like it is getting mounted read-only because an error occurred. I have changed the mount options for / in /etc/fstab to noatime,nodiratime,errors=continue and it no longer mounts the SDHC card as read-only after it resumes. So the problem is happening when it suspends, not when it resumes as I had thought. I checked /sys/bus/usb/devices/1-4/power/persist and it is set to 1. So the SDHC card shouldn't appear disconnected to the OS (or more accurately it should recover from the disconnection without error).

• about freelancer in third world countries

  - by MaKo

  hello guys, one question that is been bogging me... first of all I want to say that I actually come from a third world country, so I am all up for opportunities for everybody... so here comes my consideration,,, I have been working as a programmer for Iphone apps (noob in the company), now in my new "first" world country (immigration can be good!!!), but seem to be getting more and more advertisement from sites like freelancer.com etc,,, so I would want to know what do you think about all this???, would the jobs be getting cheaper?? if a project can be done by say 10% of the cost overseas, what is stopping the employers of doing just that? is it worth it? how about the quality? from a local job and overseas job? and all other aspects I cannot think about?? I just want to know if all this years of learning are going to pay off? or if in a near future all programming jobs will just go to cheaper labor? (sweat shops??) ok hope to make sense in my ramblings,, cheers;)

• Why is CS never a topic of conversation of the layman? [closed]

  - by hydroparadise

  Granted, every profession has it's technicalities. If you are an MD, you better know the anatomy of the human body, and if you are astronomer, you better know your calculus. Yet, you don't have to know these more advance topics to know that smoking might give you lung cancer because of carcinogens or the moon revolves around the earth because of gravity (thank you Discovery Channel). There's sort of a common knowledge (at least in more developed countries) of these more advanced topics. With that said, why are things like recursive descent parsing, BNF, or Turing machines hardly ever mentioned outsided 3000 or 4000 level classes in a university setting or between colleagues? Even back in my days before college in my pursuit of knowledge on how computers work, these very important topics (IMHO) never seem to get the light of day. Many different sources and sites go into "What is a processor?" or "What is RAM?", or "What is an OS?". You might get lucky and discover something about programming languages and how they play a role in how applications are created, but nothing about the tools for creating the language itself. To extend this idea, Dennis Ritchie died shortly after Steve Jobs, yet Dennis Ritchie got very little press compared to Steve Jobs. So, the heart of my question: Does the public in general not care to hear about computer science topics that make the technology in their lives work, or does the computer science community not lend itself to the general public to close the knowledge gap? Am I wrong to think the general public has the same thirst for knowledge on how things work as I do? Please consider the question carefully before answering or vote closing please.

• Employee Engagement: Drive Business Value

  - by Kellsey Ruppel

  As we’ve been discussing this week, employee engagement is extremely important and you’ve probably realized that effectively engaging your employees is essential to driving business value. Your employees are the ones responsible for executing on the business’ objectives. Your employees (in the sales & service departments) are the ones interacting with your customers the most, so delivering on customer expectations and attaining high levels of customer engagement are simply not possible without successfully empowering these this stakeholder group. High employee and partner engagement can have many benefits including: Higher levels of employee productivity Longer employee retention Stronger, more enduring and more successful relationships Serving as ambassadors for an organization’s brand More likely to deliver excellent customer service Referring others for hire Recommending the organization’s products and services Sharing feedback with their colleagues In a way, engagement is a measure of employee investment in an organization’s mission and brand. And then you have the enablement piece of this as well.  It’s hard to imagine a high level of engagement existing among employees who don’t feel that they’ve been enabled to do their jobs very efficiently or effectively. You’re just not going to find high engagement among people if the everyday processes and technologies  they work with make it a challenge for them to access, share and manage the information  they need do their jobs or if they’re unable to effectively collaborate around the projects they’re working on. How does your organization measure on the employee engagement spectrum? We’ve got a number of different resources to help you get started! Portal Resource Center Video: Got a minute?

• Trying to move away from PHP/Yii: RoR, Python/Django or ASP.NET MVC? Your opinions please [closed]

  - by Örs

  I have a CS degree and I've been working as a web developer (front & backend) for about 2 years now. I've been working with PHP mostly because it was easy to pick up and find a job, but I've grown to dislike the language and want to try something new, and possibly get a better paying job. That last point is especially important because in my area (Romania/Eastern Europe) PHP jobs are mostly for people fresh out of college/high school, hence the pay is rather low. I've been working with the Yii framework which, if I understand correctly, borrows a lot from Ruby on Rails (convention over configuration, MVC, Active Record, scaffolding). Other than PHP I only know curly-brace languages (C/C++/Java) and bash so Python/Ruby might be a bit challenging. On the other hand I've been using Linux (with vim and recently Sublime Text 2) for almost 4 years now so Windows and a lack of a terminal would have its downsides as well. I'm leaning towards Python/Ruby because of my *nix bias (plus both look like fun), but I've heard great things about ASP.NET MVC as well. Any suggestions? PS: I think there are more jobs in ASP.NET around here, but that's not necessarily a plus, because there are a lot of CS graduates as well. tl;dr: Romanian PHP/Yii developer trying to move to Python/Django or Ruby/Rails or C#/ASP.NET MVC. Suggestions?

• Advice on designing web application with a 40+ year lifetime

  - by user2708395

  Scenario Currently, I am apart of a health care project whose main requirement is to capture data with unknown attributes using user generated forms by health care providers. The second requirement is that data integrity is key and that the application will be used for 40+ years. We are currently migrating the client's data from the past 40 years from various sources (Paper, Excel, Access, etc...) to the database. Future requirements are: Workflow management of forms Schedule management of forms Security/Role based management Reporting engine Mobile/Tablet support Situation Only 6 months in, the current (contracted) architect/senior programmer has taken the "fast" approach and has designed a poor system. The database is not normalized, the code is coupled, the tiers have no dedicated purpose and data is starting to go missing since he has designed some beans to perform "deletes" on the database. The code base is extremely bloated and there are jobs just to synchronize data since the database is not normalized. His approach has been to rely on backup jobs to restore missing data and doesn't seem to believe in re-factoring. Having presented my findings to the PM, the architect will be removed when his contract ends. I have been given the task to re-architect this application. My team consists of me and one junior programmer. We have no other resources. We have been granted a 6-month requirement freeze in which we can focus on re-building this system. I suggested using a CMS system like Drupal, but for policy reasons at the client's organization, the system must be built from scratch. This is the first time that I will be designing a system with a 40+ lifespan. I have only worked on projects with 3-5 year lifespans, so this situation is very new, yet exciting. Questions What design considerations will make the system more "future proof"? What experiences have you had in designing such systems - both failures and successes? What questions should be asked to the client/PM to make the system more "future proof"?

• What are some good tips for a developer trying to design a scalable MySQL database?

  - by CFL_Jeff

  As the question states, I am a developer, not a DBA. I have experience with designing good ER schemas and am fairly knowledgeable about normalization and good schema design. I have also worked with data warehouses that use dimensional modeling with fact tables and dim tables. However, all of the database-driven applications I've developed at previous jobs have been internal applications on the company's intranet, never receiving "real-world traffic". Furthermore, at previous jobs, I have always had a DBA or someone who knew much more than me about these things. At this new job I just started, I've been asked to develop a public-facing application with a MySQL backend and the data stored by this application is expected to grow very rapidly. Oh, and we don't have a DBA. Well, I guess I am the DBA. ;) As far as designing a database to be scalable, I don't even know where to start. Does anyone have any good tips or know of any good educational materials for a developer who has been sort of shoved into a DBA/database designer role and has been tasked with designing a scalable database to support an application like this? Have any other developers been through this sort of thing? What did you do to quickly become good at this role? I've found some good slides on the subject here but it's hard to glean details from slides. Wish I could've attended that guy's talk. I also found a good blog entry called 5 Ways to Boost MySQL Scalability which had some good information, though some of it was over my head. tl;dr I just want to make sure the database doesn't have to be completely redesigned when it scales up, and I'm looking for tips to get it right the first time. The answer I'm looking for is a "list of things every developer should know about making a scalable MySQL database so your application doesn't perform like crap when the data gets huge".

• Do I expect too much work from an employer? [closed]

  - by Ant

  I recently switched jobs because I was not challenged enough, the work would come in waves, and I HATED the people I worked with. I am a recent college grad, May 2009, and based off the 3 internships I had, and 2 full time jobs I obtained, I am finding that employers can not keep me satisfied with the amount of work. At my new job, I like the people I work with, I am challenged, but I still do not get enough work. I hate down time. I always want to have something to work on AT LEAST 6 out of the 8 hours. I was surprised that my new employer actually hired me because the majority of the technologies they implement, I had minimal exposure to. I never programmed in the technologies they use outside of one class in college. My greatest strength is that I am an extremely fast learner. I can pick up new technologies with relative ease. They gave me a project to work on by myself and I think they assumed it would take me longer to complete. Now that I finished that app, they are struggling to find something for me to do. I am not sure if it is bad timing being close to the holidays, my manager dealing with personal issues at home, how quickly I finished the first project, or that I expect too much out of an employer? If so, what are good things to do on all this downtime?! EDIT: Thanks for all the feedback! EDIT 2: I am going to "unaccept" the answer in an effort to keep the question open. As a few people have mentioned, this is a great discussion on how to grow as a new worker in the programming field. EDIT 3: I am attempting to revive this question so the moderators will see the support to re-open it.

• The Real Value Of Certification

  - by Brandye Barrington

  I read a quote recently by Rich Hein of CIO.com "Certifications are, like most things in life: The more you put into them, the more you will get out." This is what we tell candidates all the time. The real value in obtaining a certification is the time spent preparing for the exam. All the hours spent reading books, practicing in hands-on environments, asking questions and searching for answers is valuable. It's valuable preparation for the exam, but it's also valuable preparation for your future job role and for your career. If your goal is just to pass an exam, you've missed a very important part of the value of certification.We receive so many questions through different forms of social media on whether or not certification will help candidates get jobs or get better jobs. Surveys conducted by us and by independent entities all point to the job and salary benefits of certification. However, a key part of that equation is whether a candidate can actually perform successfully in a job role. If preparation time was used to practice and learn and master new skills rather than to memorize a brain dump, the candidate will probably perform successfully in their job role, and job opportunities and higher salary will likely follow. Candidates who do not show that initiative, will not likely reap the full benefits of certification.Keep this in mind as you approach your next certification exam. You are preparing for a career, not an exam. This may help you to be more appreciative of the long hours spent studying!

• I am confused between PHP and ASP.NET to choose as a career in Indian software development context

  - by Confused_Guy

  I need your help(specially from the software professionals of India). I have completed MCA in 2009. After that instead of joining software company I did a Teaching job nearby by home. In the mean time I prepared myself for public sector jobs(bank). I continued my job for 1 year more and left it in 2010. Now in 2012 ,I feel that I should have done the software jobs,so that I could earn my bread and butter and in the mean time I could have prepared for the job.Because,according to my qualification it will give me the best salary. Now I want to go back in software industries. Now all of them are asking for experiences.And I don't have any.....So which language should I learn? And what should I do,because I have two year gap. Some of my friends suggested me to go with PHP as its easier and quicker to get job in India. But Here the PHP guys are getting less salary as compared to ASP.NET. I am planning to begin with PHP and but is it possible to switch to ASP.NET after two years experience. JAVA: I know upto servlet & JSP. Which is nothing in current market. ASP.NET: I know the basics of asp.net upto database connection ie(Gridview). PHP: Only the basics. So what should I do now. Which is most demanding. Does PHP is good, I feel its more like JSP pages. Please guide me, All your suggestions are needed for me.

• why are transaction monitors on decline? or are they?

  - by mrkafk

  http://www.itjobswatch.co.uk/jobs/uk/cics.do http://www.itjobswatch.co.uk/jobs/uk/tuxedo.do Look at the demand for programmers (% of job ads that the keyword appears), first graph under the table. It seems like demand for CICS, Tuxedo has fallen from 2.5%/1% respectively to almost zero. To me, it seems bizarre: now we have more networked and internet enabled machines than ever before. And most of them are talking to some kind of database. So it would seem that use of products whose developers spent last 20-30 years working on distributing and coordinating and optimizing transactions should be on the rise. And it appears they're not. I can see a few causes but can't tell whether they are true: we forgot that concurrency and distribution are really hard, and redoing it all by ourselves, in Java, badly. Erlang killed them all. Projects nowadays have changed character, like most business software has already been built and we're all doing internet services, using stuff like Node.js, Erlang, Haskell. (I've used RabbitMQ which is written in Erlang, "but it was small specialized side project" kind of thing). BigData is the emphasis now and BigData doesn't need transactions very much (?). None of those explanations seem particularly convincing to me, which is why I'm looking for better one. Anyone?
