  • How to setup a DotNetNuke Development Environment with Source Control?

    - by Joosh21
    My team is developing a new DotNetNuke web application and would like to know what is recommended to setup a development environment with source control and automated builds? We would like to keep the DNN source code separate from our custom modules and extensions source code. The DotNetNuke Compiled Module template for Visual Studio wants us to store the source code in the DesktopModules directory of the DNN source code and output to the DNN source code bin directory. Is this the recommended structure? I would rather keep the files in different locations, but then it becomes more difficult to run and debug locally as it would require an install of the module for each change. Also, how should an automated build deploy any changes? How have others set this up? Is there a recommended best practice?

  • How do I prepare myself for a summer of working on Python using Linux environment?

    - by Shailesh Tainwala
    Hi, I have used just Windows for programming so far. Now, I have an internship starting in two weeks and I will be using just Linux environment with Python programming language. I've installed Ubuntu on my system but have no exposure to shell scripting. I need some advice on how I can quickly learn to use the Linux terminal quickly. Any books or web resources that you can suggest? Also, is there a particular IDE that is generally preferred for Python programming on Linux, or is Vim preferred? How can I best prepare myself for the internship ahead? Thanks for taking the time.

  • How to monitor and maintain my grails application in live/production environment?

    - by fabien7474
    It is the first time I have ever launched live a website (with Grails web framework under Amazon EC2 platform and Cloud Foundry) and I realized quickly that I am not ready for monitoring and maintening correctly my application in production mode (fortunately the website is accessible to a very limited number of users) . The issues I have faced so far are: Cannot change my views. I need to redeploy my application I have no monitoring. I don't know who is connected, when do they sign in / sign out... Redploying my application (upload WAR + deploy) takes at least 30 minutes. I don't know how to restart my Tomcat server without a redeploy through Cloud Foundry ! ... So, my question is very simple: What tools (including grails plugins) and methods can you recommend me for taking me out from my current blindness?

  • Why does sh/bash set command line parameter values when trying to set environment variable?

    - by Touko
    A question on basics : While tuning environment variables for a program launched from a script, I ended up with somewhat strange behaviour with sh (which seems to be actually linked to bash) : variable setting seems to mess up with command-line parameters. Could somebody explain why does this happen? A simple script: #! /bin/sh # Messes with $1 ?? set ANT_OPTS=-Xmx512M export ANT_OPTS # Works # export ANT_OPTS=-Xmx512M echo "0 = $0" echo "1 = $1" When I run this with the upper alternative (set + export), the result is as following: $ ./test.sh foo 0 = ./test.sh 1 = ANT_OPTS=-Xmx512M But with lower alternative (export straight), the result is as I supposed: $ ./test.sh foo 0 = ./test.sh 1 = foo There is surely logical explanation, I just haven't figured it out yet. Somebody who does have idea? br, Touko

  • PHP and Apache environment variables

    - by Simon
    Hello, I want to pass an environment variable in linux to apache on start up. export MYVAR=5 --I define my environment variable on the command line PassEnv MYVAR --set apache to import the variable in apache config file apachectl restart --when I restart apache I don't get an error message. However I have noticed that if I do not create the environment variable in my first step, I get a warning message, so must be working here echo $_SERVER['MYVAR'] --i try to access the environment variable within PHP but it is not defined I've observed that if I try to PassEnv an environment variable that already exits (one that I havn't created myself) it works fine. The SetEnv directive also works fine. I'd really like to pass an environment variable to apache on the fly without writing it in a file. Help much appreciated. I'm using CentOS, PHP5 and Apache2. Thanks.

  • Is there a program devleopment environment similar to visual studios?

    - by Assimilater
    I'm getting really tired of working against click-once and I'm wondering if there's a better alternative. I'm looking for a programming environment that preferably does not depend on the .net framework. I'm not sure how much .net does for me exactly (though I have some idea) but I'd like to make my programs as independent of downloading a microsoft or other framework. I often think of professional programs like itunes, gimp or firefox that don't require someone to have a .net framwork. I'd also like to have these programs work on windows mac and linux. Any suggestions?

  • Is my Perl script grabbing environment variabless from "someplace else"?

    - by Michael Wilson
    On a Solaris box in a "mysterious production system" I'm running a Perl script that references an environment variable. No big deal. The contents of that variable from the shell both pre- and post-execution are what I expect. However, when reported by the script, it appears as though it's running in some other sub-shell which is clobbering my vars with different values for the duration of the script. Unfortunately I really can't paste the code. I'm trying to get an atomic case, but I'm at my wit's end here.

  • Latest Security Updates for Java are Available for Download

    - by Akemi Iwaya
    Oracle has released new updates that patch 40 security holes in their Java Runtime Environment software. Anyone who needs or actively uses the Java Runtime Environment for work or gaming should promptly update their Java installation as soon as possible. One thing to keep in mind is that there are limitations placed on updates for older versions of Java as shown in the following excerpt. If you are using an older version, then it is recommended that you update to the Java SE 7 release if possible (depending on your usage circumstances). From the The H Security blog post: Only the current version of Java, Java SE 7, will be updated for free; downloads of the new version, Java SE 7 Update 25, are available and existing installs should auto-update. Mac OS X users will get an updated Java SE 6 for their systems as an automatic update; Java SE 7 on Mac OS X is updated by Oracle. Users of other older versions of Java will only get updates if they have a maintenance contract with Oracle. Affected Product Releases and Versions: JDK and JRE 7 Update 21 and earlier JDK and JRE 6 Update 45 and earlier JDK and JRE 5.0 Update 45 and earlier JavaFX 2.2.21 and earlier Note: If you do not need Java on your system, we recommend uninstalling it entirely or disabling the browser plugin. You can download and read through the details about the latest Java updates by visiting the links shown below.

  • A list of pros and cons to giving developers “Local Admin” privileges to their machines? [closed]

    - by Boden
    Possible Duplicate: Is local “User” rights enough or do developers need Local Administrator or Power User while coding? I currently work for a large utilities company which currently does not grant “Local Admin” access to developers. This is causing a lot of grief as anything that requires elevated privileges needs to be done by the Desktop Support/Server Teams. In some cases this can take several days and requires our developers to have to show why they need this access. I personally think that all developers should have local administration rights and are currently fighting with management to achieve this but I would like to know what other people think about this. To achieve this I would like to hear what people believe are the pros and cons of letting developers have local admin access to their machines. Here are some I have come up with: Pros Loss time is keep low as developers can resolve issues that would normally require Local Admin Evaluation of tools and software are possible to improve productivity Desktop support time not wasted installing services and software on developers PC Cons Developers install software on local PC that could be malicious to others or inappropriate in a business environment Desktop Support required to support a PC that is not the norm Development done with admin access that then fails when promoted to another environment that does not have the same access level

  • For those of you who are senior developers what do you look for in a new company and development team?

    - by Amy P
    As I move forward in my career new jobs become more difficult to choose between. When I was starting out and for the first 8 years of my career I took the jobs that I could get that would keep me programming on the general technological path that I was on. I am a job hopper, I only stay with a company for between 2 - 3 years. I think that I do this because after 2 years I get bored and unless there are new projects to keep my busy I no longer find work interesting. Now that I am becoming more experienced it is more important for me to only apply for jobs that are interesting and will move my career and my skill set forward. My problem now is that I keep finding jobs where the projects appear to be interesting during the interview but once I get in the company I find the development environment is sub-par and the development team is disjointed. I feel like I am asking the wrong questions during the interview process and don't know what to look for to make sure that the environment I will be working in will be a good one. Now my question: For those of you who are senior developers what do you look for in a new company and development team? I am looking for the key qualities in a company and development team that you look for when interviewing with a company. These qualities are the ones that would give you hints that the company will be a good one to work for.

  • Extend Your Applications Your Way: Oracle OpenWorld Live Poll Results

    - by Applications User Experience
    Lydia Naylor, Oracle Applications User Experience Manager At OpenWorld 2012, I attended one of our team’s very exciting sessions: “Extend Your Applications, Your Way”. It was clear that customers were engaged by the topics presented. Not only did we see many heads enthusiastically nodding in agreement during the presentation, and witness a large crowd surround our speakers Killian Evers, Kristin Desmond and Greg Nerpouni afterwards, but we can prove it…with data! Figure 1. Killian Evers, Kristin Desmond, and Greg Nerpouni of Oracle at the OOW 2012 session. At the beginning of our OOW 2012 journey, Greg Nerpouni, Fusion HCM Principal Product Manager, told me he really wanted to get feedback from the audience on our extensibility direction. Initially, we were thinking of doing a group activity at the OOW UX labs events that we hold every year, but Greg was adamant- he wanted “real-time” feedback. So, after a little tinkering, we came up with a way to use an online survey tool, a simple QR code (Quick Response code: a matrix barcode that can include information like URLs and can be read by mobile device cameras), and the audience’s mobile devices to do just that. Figure 2. Actual QR Code for survey Prior to the session, we developed a short survey in Vovici (an online survey tool), with questions to gather feedback on certain points in the presentation, as well as demographic data from our participants. We used Vovici’s feature to generate a mobile HTML version of the survey. At the session, attendees accessed the survey by simply scanning a QR code or typing in a TinyURL (a shorthand web address that is easily accessible through mobile devices). Killian, Kristin and Greg paused at certain points during the session and asked participants to answer a few survey questions about what they just presented. Figure 3. Session survey deployed on a mobile phone The nice thing about Vovici’s survey tool is that you can see the data real-time as participants are responding to questions - so we knew during the session that not only was our direction on track but we were hitting the mark and fulfilling Greg’s request. We planned on showing the live polling results to the audience at the end of the presentation but it ran just a little over time, and we were gently nudged out of the room by the session attendants. We’ve included a quick summary below and this link to the full results for your enjoyment. Figure 4. Most important extensions to Fusion Applications So what did participants think of our direction for extensibility? A total of 94% agreed that it was an improvement upon their current process. The vast majority, 80%, concurred that the extensibility model accounts for the major roles involved: end user, business systems analyst and programmer. Attendees suggested a few supporting roles such as systems administrator, data architect and integrator. Customers and partners in the audience verified that Oracle‘s Fusion Composers allow them to make changes in the most common areas they need to: user interface, business processes, reporting and analytics. Integrations were also suggested. All top 10 things customers can do on a page rated highly in importance, with all but two getting an average rating above 4.4 on a 5 point scale. The kinds of layout changes our composers allow customers to make align well with customers’ needs. The most common were adding columns to a table (94%) and resizing regions and drag and drop content (both selected by 88% of participants). We want to thank the attendees of the session for allowing us another great opportunity to gather valuable feedback from our customers! If you didn’t have a chance to attend the session, we will provide a link to the OOW presentation when it becomes available.

  • ATG Live Webcast June 28: Scrambling Sensitive Data in EBS 12 Cloned Environments

    - by BillSawyer
    Securing the Oracle E-Business Suite includes protecting the underlying E-Business data in production and non-production databases.  While steps can be taken to provide a secure configuration to limit EBS access, a better approach to protecting non-production data is simply to scramble (mask) the data in the non-production copy.   The Oracle E-Business Suite Template for Data Masking Pack can be used in situations where confidential or regulated data needs to be shared with other non-production users who need access to some of the original data, but not necessarily every table.  Examples of non-production users include internal application developers or external business partners such as offshore testing companies, suppliers or customers. The Oracle E-Business Suite Template for Data Masking Pack is applied to a non-production environment with the Enterprise Manager Grid Control Data Masking Pack.  When applied, the Oracle E-Business Suite Template for Data Masking Pack will create an irreversibly scrambled version of your production database for development and testing. This ATG Live Webcast is your chance to come learn about the Oracle E-Business Suite Release 12.1.3 Template for Data Masking Pack from the experts. Oracle E-Business Suite Release 12.1.3 Template for Data Masking The agenda for the Oracle E-Business Suite Template for Data Masking Pack webcast includes the following topics: What does data masking do in E-Business Suite environments? De-identify the data Mask sensitive data Maintain data validity How can EBS customers use data masking?

  • New Working Environment Starting November

    - by Jenson
    Normal 0 false false false EN-GB X-NONE X-NONE MicrosoftInternetExplorer4 This is actually a post dated update. After I’ve been working in the private sectors for so many years (the 2 years when I was working as IT trainer in a secondary school is not counted, as I was working under a contract with a private IT training agency), I’ve decided to try my luck into public sector. And fortunately, I passed the interview and I was offered a position of Web Administrator in a government statutory board, that’s Agency for Science, Technology and Research (of Singapore). During my previous employment with a Japanese MNC (multinational company), it was a totally new environment for me, as I had never worked for a Japanese company before, but the first time I work for Japanese company also gave me the very first nightmare I have with them, and vowed not to work for them anymore, and any other Japanese companies. No doubt I have freedom of choosing the tools and methods I wish to use for the projects, but the project management is simply too messy and out of order. And a lot of time, I don’t find that everyone is working as a team, more like achieving their own goals. Accountability for project is not shared, all lumped onto the shoulders of the developer in charge (they called it Software Engineer). I was working on a windows based .NET project, which I already voiced out that it’s not manageable by just 1 software engineer, but it seems like nobody cares, even the one who propose the solution to customer doesn’t care much. What he cares is whether you deliver the project on time so that he can please his customer and the senior management of his good work. Too many stories to tell, and I just simple doesn’t want to talk too much on this as it has already became the past to me. With my new title with the government agency, I hope to contribute my best to them, while learning as much as I can. I will share whatever I can on technologies, methodologies, and etc whichever I’m allowed and permitted to (of course, for those non-work-related stuff, I would be glad to share with you without much hesitation). Thank you! /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin-top:0cm; mso-para-margin-right:0cm; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0cm; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

  • SSI: Failed String Comparison with CGI Environment Variable [migrated]

    - by Calyo Delphi
    I am currently working on developing a personal website. It's not my first time doing this, but this is my first major foray into implementing SSI. I've run myself into a wall, however, with an if-else directive that uses one of the CGI environment variables as part of its comparison. Even after some limited attempts at debugging, all of the output and documentation that I have means that the comparisons being made should fail outright. This is not the case, and the wrong evaluation is being made by the if-else directive. Here's the code in the file index.shtml: <head> <!--#set var="page" value="Home" --> <!--#include file="headlinks.shtml" --> <style> img#ref { float: right; margin-left: 8px; border-width: 0px; } </style> </head> Here's the code in the file headlinks.shtml: <title><!--#echo var="page" --> &ndash; <!--#echo var="HTTP_HOST" --></title> <!--#set var="docroot" value="${DOCUMENT_ROOT}" --> <!--#echo var="docroot" --> <!--#if expr="( $docroot != '/Applications/MAMP/htdocs' ) || ( $docroot != '/home/dragarch/public_html' )" --> <link rel="stylesheet" type="text/css" href="../style.css"> <link rel="shortcut icon" type="image/svg+xml" href="../favicon.svg" /> <!--#else --> <link rel="stylesheet" type="text/css" href="style.css"> <link rel="shortcut icon" type="image/svg+xml" href="favicon.svg" /> <!--#endif --> And here's the output for the file index.shtml: <title>Home &ndash; dragarch</title> /Applications/MAMP/htdocs <link rel="stylesheet" type="text/css" href="../style.css"> <link rel="shortcut icon" type="image/svg+xml" href="../favicon.svg" /> Both style.css and favicon.svg are in the document root with index.shtml, so the if directive should fail and default to the output of the else directive. As you can see, while the document root (which is currently the MAMP htdocs folder on my own notebook) is correct according to the output of the echo directive, the comparison in the if-else directive fails to compare the strings properly. I'm using this page for my documentation: http://httpd.apache.org/docs/2.2/mod/mod_include.html I'm at a complete loss as to why this is the case, and need a bit of help here. EDIT: I should note that dragarch is a hostname that I configured in /etc/hosts to point to 127.0.0.1 so I could test the site without having to use localhost. It has no real effect on the functionality of anything, other than to just act as a prettier hostname to use.

  • Soft lockup after upgrade - cannot install from live CD

    - by nbm
    I dual-boot MacIntel Core 2 duo. nVidia graphics. Ran upgrade from ubuntu 13.10 to 14.04 (64 bit). On restart ran into {numbers} Bug: soft lockup - CPU#0 stuck for 22s! [swapper/0:1] Tried loading earlier kernel: same problem Tried re-installing ubuntu from a liveCD that has worked in the past: version 13.04. Same problem. Tried re-partitioning hard drive using Mac OS X disk utility and then installing ubuntu 14.04LTS from liveCD. Same problem. Not possible to verify liveCD disk (creates same "soft lockup" bug.) Tried installing from the liveCD with version 13.04 that I know works (that's how I got Ubuntu on this machine in the first place.) Same problem. I know this is not a hardware problem as OS X works just fine, I am using it right now on the same machine. I have been using various versions of Ubuntu for 2 years. Things I cannot do: Open a terminal Verify CD image Start ubuntu from CD (same soft lockup problem) This problem is similar to some other questions, none of which have been satisfactorily answered: Ubuntu 14.04 soft lockup on Vostro 3500 Cannot do fresh install of Ubuntu 13.04 while booting from DVD: "soft lockup" bug Live CD stalls when installing Ubuntu 13.10 UPDATE 6/11/14: Following some much-appreciated advice from bain (see below) I burned a 12.04LTS disk and started with kernel parameters: noapic, no1apic, acpi=off, nomodeset, elevator=deadline, and clocksource=jiffies. With all of these parameters I was able to load the 12.04LTS CD ("Try without installing"). It worked fine. However, as soon as I tried to install Ubuntu from the CD, my wired ethernet (eth0) connection would hang. There are already various askubuntu questions and bug reports about this problem, none of which had answers for me. (E.g., dhclient eth0 does nothing, none of the various reset commands does anything, manually setting IP &etc does nothing. I could reliably kill the ethernet connection by clicking "install ubuntu" every single time.) I could go ahead and install 12.04 without an internet connection, but the install would freeze after mostly completing (I tried several times.) There were some relevant error messages in the details of the install output script that, IIRC, had to do with searching for missing files and not being able to access eth0 (internet) to get them. To be honest I gave up at that point and I'm not sure I wrote those down. If I find some notes I will post them. At this point I no longer have Ubuntu on my system. I wiped the partitions and am using exclusively OS X. I am leaving this question in case it helps anyone else with similar problems. I love open source and I love Linux, and the next machine I get I will probably just build from Arch. At the moment I miss repositories and a lot of other things about Ubuntu, but the OS X terminal is 'nix, I can pretty much use all the open source apps I like, and while I am not a fan of the Apple software it gets the job done for me. Unlike Ubuntu, which can't even install. I realize this isn't necessarily a place for a soapbox speech, but when I first installed 12.04 several years ago there were already people in the community complaining that Canonical was going too "commercial". But I loved it. Several years later and all I've seen is Canonical adding more not-so-useful bells and whistles to Ubuntu while continually failing to fix basic problems on upgrades. With a dual-boot (and sometimes triple-boot) system it always took me some tweaking to get an upgrade to work, and to some extent that is okay. But at this point I feel like Canonical ought to just put a price tag on Ubuntu. All I see is more commercialism and advertising and product tie-ins, and ongoing problems do not get fixed. I am a big fan of open-source, not-for profit enterprise. I am also a big fan of for-profit enterprise, which certainly has its place and usefulness. I am not a fan of companies who pretend to be in favor of open source but really are just out to make a buck, and IMNSHO that is what Canonical has become. This is a great community and I wish you all the best, but my next install of Linux will not be Ubuntu.

  • How do I create a safe local development environment?

    - by docgnome
    I'm currently doing web development with another developer on a centralized development server. In the past this has worked alright, as we have two separate projects we are working on and rarely conflict. Now, however, we are adding a third (possible) developer into the mix. This is clearly going to create problems with other developers changes affecting my work and vice versa. To solve this problem, I'm thinking the best solution would be to create a virtual machine to distribute between the developers for local use. The problem I have is when it comes to the database. Given that we all develop on laptops, simply keeping a local copy of the live data is plain stupid. I've considered sanitizing the data, but I can't really figure out how to replace the real data, with data that would be representative of what people actually enter with out repeating the same information over and over again, e.g. everyone's address becomes 123 Testing Lane, Test Town, WA, 99999 or something. Is this really something to be concerned about? Are there tools to help with this sort of thing? I'm using MySQL. Ideally, if I sanitized the db it should be done from a script that I can run regularly. If I do this I'd also need a way to reduce the size of the db itself. (I figure I could select all the records created after x and whack them and all the records in corresponding tables out so that isn't really a big deal.) The second solution I've thought of is to encrypt the hard drive of the vm, but I'm unsure of how practical this is in terms of speed and also in the event of a lost/stolen laptop. If I do this, should the vm hard drive file itself be encrypted or should it be encrypted in the vm? (I'm assuming the latter as it would be portable and doesn't require the devs to have any sort of encryption capability on their OS of choice.) The third is to create a copy of the database for each developer on our development server that they are then responsible to keep the schema in sync with the canonical db by means of migration scripts or what have you. This solution seems to be the simplest but doesn't really scale as more developers are added. How do you deal with this problem?

  • Cloud9 + vmware server

    - by Vigrond
    I recently bought a Chromebook to allow me to travel and work easily. My work likes to use VMWare images for our environments. I would like to run these on a server somewhere and hook them up to Cloud9 IDE so I can program fairly easily with my Chromebook What would be the easiest way to set this environment up? Can you say, take a VMWare image, "run" it on a linux server and hook up secure access to it through a given port?

  • Difference between Windows and Linux development environments?

    - by Ryan
    I have an interview coming up soon for a Business Analyst position and the recruiter mentioned some feedback from a prior candidate that was interviewed who said the interviewers asked him what the difference between a Windows and Linux development environment was. Are there some high level things I need to be aware of from a business point of view when working with a development team or designing an application on Windows vs Linux?

  • Stuff every programmer needs while working

    - by Desai Shukla
    I've been tasked with creating a fun and relaxing environment, one thing I know that I want is ergonomic mice and keyboards, others have suggested exercise balls and bands. What is it that every programmer needs while working? What might not be necessary but would be nice to have anyway? Note: this question was asked previously, but has been recommended to be posted here.

  • What non-computer based programming tools do you consider invaluable? [closed]

    - by Schroedinger
    Possible Duplicate: What physical tools do you find useful to work as a programmer? I'm talking about things like whiteboards for process planning, paper for mapping out logic flows, particular books that you've found relevant, things in your workspace that help you think and process what you're working on and how to attack problems. I'm starting out in a corporate environment and want to have an understanding of what tools really work for other programmers to help them work through their problems and solutions.

  • Publishing to live website

    - by Alienfluid
    Hey there, My friend and I are collaborating on a ASP.NET powered website. To develop it locally, we use Visual Web Developer Express (good enough for our needs). Subversion (using Tortoise SVN) is our source control of choice with the repository residing on Unfuddle.com. We run into problems when we need to update the live site - since there's no version control on it. Currently we use the "Copy to Website" feature in VWD which copies the files using FTP. Here are some problems: VWD only keeps track of files uploaded by one user, so if the other user uploads a newer version of a file to the live site, VWD on my side cannot tell whether the live version of the file is newer or mine is. There's no way to tell whether all the latest changes are available on the live site. We have to be careful not to party all over the shared web.config file since the other user's local DB settings are different from mine, and of course, the live DB settings are a whole other story! What do you guys use to publish to a live site? Does anything out there tie into Subversion so that we can automate the process and always guarantee that the live site is synced to a change list number? Also, how do you manage the different web.config file settings? Thanks!
