  • Why I love NUnit, NCover, CC Nant and friends

    - by gregarobinson
    I have used these opensource tools on past projects in different stages, but never all of them at once. I am on a project now where there is a build server, Subversion, Nant, NUnit with 100% NCover required coverage, CrusieControl, CCTray and Rhino Mockc.I was extending an Interface and concrete class in a solution I had never worked on before today. Automatic builds were turned off for the day for a special case QA test. I added my new members to the Interface, implemented them in the concrete class, did a local build, tested, all looked good, so I did a Subversion Update then Commit.  Around 4:30PM the automatic builds were turned back on. Right away the build failed for less than 100% code coverage on my last Commit. Turns out there was a project in the solution I modified that had numerous NUnit tests on the Interface/Concrete class I modified, 3 of which now failed. Now that is cool..of course i was frustrated as i wanted to go home..but..I did a bad thing..I did not run nant on the source prior to my Commit. Lesson learned, and a great lesson at that!

  • Assigning resources to MS Project 2007

    - by adam
    Hi, I'm planning a redesign of a site in Project 2007. I have three developers to hand, all with the same skills. There are about 80 templates to be rendered as part of the redesign, and each template has been added as a project task. Each of these tasks can be done by any of the 3 devs, and each will take a day (with a few exceptions). There is no order in which the tasks must be completed, so there are no predecessor rules. I'd like to be able to assign tasks to a 'Developer' resource group, and for Project to see that three tasks can be done at once (as the group has three resources members) and queue the tasks as such. Googling leads me to Team Assignment, but that appears to be part of Project Server. Surely I can do this in standalone Project? Thanks, Adam

  • Who writes the words? A rant with graphs.

    - by Roger Hart
    If you read my rant, you'll know that I'm getting a bit of a bee in my bonnet about user interface text. But rather than just yelling about the way the world should be (short version: no UI text would suck), it seemed prudent to actually gather some data. Rachel Potts has made an excellent first foray, by conducting a series of interviews across organizations about how they write user interface text. You can read Rachel's write up here. She presents the facts as she found them, and doesn't editorialise. The result is insightful, but impartial isn't really my style. So here's a rant with graphs. My method, and how it sucked I sent out a short survey. Survey design is one of my hobby-horses, and since some smartarse in the comments will mention it if I don't, I'll step up and confess: I did not design this one well. It was potentially ambiguous, implicitly excluded people, and since I only really advertised it on Twitter and a couple of mailing lists the sample will be chock full of biases. Regardless, these were the questions: What do you do? Select the option that best describes your role What kind of software does your organization make? (optional) In your organization, who writes the text on your software user interfaces? (for example: button names, static text, tooltips, and so on) Tick all that apply. In your organization who is responsible for user interface text? Who "owns" it? The most glaring issue (apart from question 3 being a bit broken) was that I didn't make it clear that I was asking about applications. Desktop, mobile, or web, I wouldn't have minded. In fact, it might have been interesting to categorize and compare. But a few respondents commented on the seeming lack of relevance, since they didn't really make software. There were some other issues too. It wasn't the best survey. So, you know, pinch of salt time with what follows. Despite this, there were 100 or so respondents. This post covers the overview, and you can look at the raw data in this spreadsheet What did people do? Boring graph number one: I wasn't expecting that. Given I pimped the survey on twitter and a couple of Tech Comms discussion lists, I was more banking on and even Content Strategy/Tech Comms split. What the "Others" specified: Three people chipped in with Technical Writer. Author, apparently, doesn't cut it. There's a "nobody reads the instructions" joke in there somewhere, I'm sure. There were a couple of hybrid roles, including Tech Comms and Testing, which sounds gruelling and thankless. There was also, an Intranet Manager, a Creative Director, a Consultant, a CTO, an Information Architect, and a Translator. That's a pretty healthy slice through the industry. Who wrote UI text? Boring graph number two: Annoyingly, I made this a "tick all that apply" question, so I can't make crude and inflammatory generalizations about percentages. This is more about who gets involved in user interface wording. So don't panic about the number of developers writing UI text. First off, it just means they're involved. Second, they might be good at it. What? It could happen. Ours are involved - they write a placeholder and flag it to me for changes. Sometimes I don't make any. It's also not surprising that there's so much UX in the mix. Some of that will be people taking care, and crafting an understandable interface. Some of it will be whatever text goes on the wireframe making it into production. I'm going to assume that's what happened at eBay, when their iPhone app purportedly shipped with the placeholder text "Some crappy content goes here". Ahem. Listing all 17 "other" responses would make this post lengthy indeed, but you can read them in the raw data spreadsheet. The award for the approach that sounds the most like a good idea yet carries the highest risk of ending badly goes to whoever offered up "External agencies using focus groups". If you're reading this, and that actually works, leave a comment. I'm fascinated. Who owned UI text Stop. Bar chart time: Wow. Let's cut to the chase, and by "chase", I mean those inflammatory generalizations I was talking about: In around 60% of cases the person responsible for user interface text probably lacks the relevant expertise. Even in the categories I count as being likely to have relevant skills (Marketing Copywriters, Content Strategists, Technical Authors, and User Experience Designers) there's a case for each role being unsuited, as you'll see in Rachel's blog post So it's not as simple as my headline. Does that mean that you personally, Mr Developer reading this, write bad button names? Of course not. I know nothing about you. It rather implies that as a category, the majority of people looking after UI text have neither communication nor user experience as their primary skill set, and as such will probably only be good at this by happy accident. I don't have a way of measuring those frequency of those accidents. What the Others specified: I don't know who owns it. I assume the project manager is responsible. "copywriters" when they wish to annoy me. the client's web maintenance person, often PR or MarComm That last one chills me to the bone. Still, at least nobody said "the work experience kid". You can see the rest in the spreadsheet. My overwhelming impression here is of user interface text as an unloved afterthought. There were fewer "nobody" responses than I expected, and a much broader split. But the relative predominance of developers owning and writing UI text suggests to me that organizations don't see it as something worth dedicating attention to. If true, that's bothersome. Because the words on the screen, particularly the names of things, are fundamental to the ability to understand an use software. It's also fascinating that Technical Authors and Content Strategists are neck and neck. For such a nascent discipline, Content Strategy appears to have made a mark on software development. Or my sample is skewed. But it feels like a bit of validation for my rant: Content Strategy is eating Tech Comms' lunch. That's not a bad thing. Well, not if the UI text is getting done well. And that's the caveat to this whole post. I couldn't care less who writes UI text, provided they consider the user and don't suck at it. I care that it may be falling by default to people poorly disposed to doing it right. And I care about that because so much user interface text sucks. The most interesting question Was one I forgot to ask. It's this: Does your organization have technical authors/writers? Like a lot of survey data, that doesn't tell you much on its own. But once we get a bit dimensional, it become more interesting. So taken with the other questions, this would have let me find out what I really want to know: What proportion of organizations have Tech Comms professionals but don't use them for UI text? Who writes UI text in their place? Why this happens? It's possible (feasible is another matter) that hundreds of companies have tech authors who don't work on user interfaces because they've empirically discovered that someone else, say the Marketing Copywriter, is better at it. And once we've all finished laughing, I'll point out that I've met plenty of tech authors who just aren't used to thinking about users at the point of need in the way UI text and embedded user assistance require. If you've got what I regard, perhaps unfairly, as the bad kind of tech author - the old-school kind with the thousand-page pdf and the grammar obsession - if you've got one of those then you probably are better off getting the UX folk or the copywriters to do your UI text. At the very least, they'll derive terminology from user research.

  • How do I nstall MS Office 2010 via WINE?

    - by Emeris
    I am trying to install MS Office 2010 on Ubuntu 12.04 on my new MacBook Pro (15"). I already read and followed every existing threads on forums and followed every existing tutorial, but my problem seem unique so far, since whichever solution I try, the problem remains. When I launch PlayOnLinux, two boxes appear one after the other (before the latest upgrade of Ubuntu of last week, the second box did not appear, only the first one did); the first one tells me: Error: PlayOnLinux is unable to find 32-bits OpenGL libraries. You might encounter problem with your games." When I close this window, a second one pops up, stating: Error: PlayOnLinux cannot find 7z. You should install it to use PlayOnLinux. Of course, I tried purging PlayOnLinux (uninstalling it and re-installing it). I also tried other versions of PlayOnLinux. Nothing matters: the problem remains. I did not succeed so far to install 32-bits OpenGL libraries, since I have a Radeon graphics card (which seems to be unusual) and I just cannot find these libraries. Once the two "error" boxes are closed, PlayOnLinux is open, but does not seem to work properly; when I try to install Microsoft Office 2010, nothing happens. When I try to close PlayOnLinux, it is even worse: Unity seems unable to close it (I even had a frozen screen when trying to xkill it through the terminal). I am looking forward to any tips that could help. P.S.: 01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Whistler [AMD Radeon HD 6600M Series]

  • WordPress page title repeated in SOME pages

    - by cmykrgbb
    I have created a Wordpress site and titles were working just fine. Then, some time and plugins installed later, I noticed that in SOME pages I get the title repeated 2 times. Example of wrong page title: Contact - NAME | NAME Example of normal title: Our Services | NAME Now, if I go to General Settings and change title it will change both, no improvement. SEO by Yoast has the option to reset page titles, but that just removes all titles leaving the current URL as page title, so no good either. Here is the code I originally had: <title><?php wp_title(''); ?><?php if(wp_title('', false)) { echo ' | '; } ?><?php bloginfo('name'); ?></title> Here is the code I am using now: <title><?php wp_title('|'); ?></title> To sum up, I think somewhere in the database there's a wp_title repeated: once using '-' as separator, another one (the current one) using '|'. Any help will be most appreciated, thanks!

  • Implementing a multilanguage AI contest platform

    - by Alejandro Piad
    This is a followup to this question. To sum: I'm implementing an AI contest site, where each user may submit several AI implementations for different games. Think about Google AI Challenge but instead of just having a big event once a year, I would like it more on a league fashion, with all virtual players playing with each other every some close period of time. I want to support as many programming languages as possible. I've seen that contest sites (like codeforces) ask you to submit a source code and interact through stdin and stdout. The first question is: what is the best way of supporting multiple languages? As I see it, I can either ask people to upload some binary/script, and interact either through stdin/*stdout*, or sockets, or the file system; or ask people to submit source code, and wrap it with whatever is necessary for the interaction. I would like to skip the need to compile the code by myself (in the server, I mean), but I am willing to do it if its the "best" choice. I need to comunicate virtual players with each other, or even better, with some intermediary arbiter. The second question is regarding security. If I'm going to be running user code in my server, I want to ensure strict security conditions, like no file system access, no networking, etc. Otherwise it would be a safe heaven for hackers. I will be implementing the engine/arbiter in .NET. I would like to support at least C#, C++, Java and Python for the user's implementations. I'm willing to write interfaces for each of these languages to simplify the user interaction with the system. Thanks in advance.

  • Is a Model Driven Architecture in Language Oriented Programming (MPS) feasible at this time

    - by Steven Jeuris
    As a side project I am developing some sort of DSL where I describe a data model, and generate desired code files from it. I believe this is called Model Driven Architecture. My partial existing implementation uses C#, CodeDOM, XML and XSLT to do this manually. I discovered there already exist better environments to do this in. The one which fascinated me the most is called MPS, which follows the Language Oriented Programming paradigm. This article, written by a cofounder of JetBrains was a real eye opener for me. I truly believe LOP has a very good chance of becoming the next big programming paradigm once it has broader support. From my short experience with MPS, I noticed it is still mainly Java-oriented. My question is, how feasible is it to generate code files for other (multiple) languages instead of just Java. I don't need full language support from the start, so preferably, I need to be able to implement a language in a agile way. E.g. first support only one type, add access modifiers, ... Perhaps some other (free) environment already provides this out of the box. P.S.: I find it important to have a lot of control over the naming conventions and such of the generated code. This is one of the reasons why I started my own implementation.

  • Fiber-Optic Cable Trick Brings Remote Triggering to Older Flashes

    - by Jason Fitzpatrick
    Many older flashes lack for a jack to input a sync cable and rely exclusively on a simple slave mode triggered by the primary flash. This hack uses a piece of scrap fiber optic cable to trigger the flash in bright conditions. Using a flash as an optical slave indoors isn’t much of a problem, but if you introduce bright light (such as outdoor lighting conditions), the ambient light can overpower the small on-camera flash and render the optical slave function useless. To overcome this, Marcell over at Fiber Strobe (a blog dedicated to cataloging experiments in incorporating fiber optics into photography) came up with a simple work around. By using some foam crafting materials and tape, he whipped up a simple mount for a strand of scrap fiber optic cable to connect between the on-camera flash and the sensor on the slave flash. Once attached it works exactly like as sync cable would, except it’s transmitting a pulse of light instead of a pulse of electricity. Hit up the link below for more pictures and a build guide.

  • Windows Azure Virtual Machines - Make Sure You Follow the Documentation

    - by BuckWoody
    To create a Windows Azure Infrastructure-as-a-Service Virtual Machine you have several options. You can simply select an image from a “Gallery” which includes Windows or Linux operating systems, or even a Windows Server with pre-installed software like SQL Server. One of the advantages to Windows Azure Virtual Machines is that it is stored in a standard Hyper-V format – with the base hard-disk as a VHD. That means you can move a Virtual Machine from on-premises to Windows Azure, and then move it back again. You can even use a simple series of PowerShell scripts to do the move, or automate it with other methods. And this then leads to another very interesting option for deploying systems: you can create a server VHD, configure it with the software you want, and then run the “SYSPREP” process on it. SYSPREP is a Windows utility that essentially strips the identity from a system, and when you re-start that system it asks a few details on what you want to call it and so on. By doing this, you can essentially create your own gallery of systems, either for testing, development servers, demo systems and more. You can learn more about how to do that here: http://msdn.microsoft.com/en-us/library/windowsazure/gg465407.aspx   But there is a small issue you can run into that I wanted to make you aware of. Whenever you deploy a system to Windows Azure Virtual Machines, you must meet certain password complexity requirements. However, when you build the machine locally and SYSPREP it, you might not choose a strong password for the account you use to Remote Desktop to the machine. In that case, you might not be able to reach the system after you deploy it. Once again, the key here is reading through the instructions before you start. Check out the link I showed above, and this link: http://technet.microsoft.com/en-us/library/cc264456.aspx to make sure you understand what you want to deploy.

  • Why does my $LD_LIBRARY_PATH get unset when using screen with bash?

    - by UltraNurd
    This is related to http://superuser.com/questions/27376/why-does-my-ld-library-path-get-unset-launching-terminal, but a different set of symptoms. First, /usr/bin/screen is setuid as per the other question. Second, the default shell on this system is /bin/tcsh for various historical reasons, and we're not allowed to chsh to /bin/bash, so I typically run bash manually immediately after login. Third, I almost always use screen, but I want ctrl-a ctrl-c in screen to create a new bash "tab", so I always invoke bash first. That is: {~} $ echo $SHELL /bin/tcsh {~} $ bash [~] echo $SHELL /bin/bash [~] screen -U [~] ...and when reconnecting: {~} $ echo $SHELL /bin/tcsh {~} $ screen -dUr [~] echo $SHELL /bin/bash [~] However, my $LD_LIBRARY_PATH is there in tcsh, there in bash, but empty once I run screen; it is still present if I just run screen from tcsh, but then I get new tcsh "tabs" when I use ctrl-a ctrl-c in screen. Any ideas?

  • Add a Real-Time Earth Wallpaper App to Ubuntu with xplanetFX

    - by Asian Angel
    Are you tired of the same old wallpaper on your Ubuntu desktop? Now you can go from blah to literally spacious, real-time styled views of Earth with the xplanetFX Wallpaper App for Linux. You can conveniently access the “file type” downloads, screenshots, and jump-to links all on the front page. For our example we downloaded the .deb setup file on our system. The setup file will need to download three additional files to complete the setup process. After those are downloaded all dependencies will have been met and you can complete the installation process. Once that is done you can find xplanetFX by going to the Accessories Section of your Ubuntu Menu. This is what the main control window looks like when you start xplanetFX for the first time. You should take a few moments to look through the various tabs and tweak the settings for items like location, screen resolution, timing, auto-start, etc. When you are done click on Execute and within a few moments your desktop will have a fresh new look! Note: It took ~30 seconds for the display to activate on our system. Have fun with xplanetFX! xplanetFX Homepage [via OMG!

  • What are the advantages of Maven when it comes to single man, educational projects

    - by Leron
    I've spend a few hours playing around with Maven + reading some stuff on the apache official site and also a few random googled articles. By this I mean that I really tried to find the answers myself - both by reading and by doing things on my own. Also maybe worth to mention that I installed the m2e plugin so most of the time I've tried things out from Eclipse and not using the command line too much. However aside from the generated project that for example prevent me from using the default package I didn't see that much of a difference with the standard way I've created my projects before try Maven. In fact I've almost decided to skip Maven for now and move on to the other technology I wanted to learn more in-depth - Hibernate, but when I start with opening the official page the first thing I've read was the recommendation to use Hibernate with Maven. That get me confused and made me taking a step back and trying once more to find what I'm obviously missing right now. As it's said in the maven.apache.. site, the true strength of Maven is shown when you work on large projects with other people, but I lack the option to see how Maven is really used in this scenario, still i think that there are maybe advantages even when it comes to working with small projects alone, but I really have difficulties to point them out. So what do you think are the advantages of Maven when it's used for small projects writing from a single person. What are the things that I should be aware of and try to exploit (I mean features offered by Maven) that can come in handy in this situations?

  • Clusterware 11gR2 &ndash; Setting up an Active/Passive failover configuration

    - by Gilles Haro
    Oracle provides many interesting ways to ensure High Availability. Dataguard configurations, RAC configurations or even both (as recommended for a Maximum Available Architecture - MAA) are the most frequently found. But when it comes to protecting a system with an Active/Passive architecture with failover capabilities, one often thinks to expensive third party cluster systems. Oracle Clusterware technology, which comes free with Oracle Database, is – in the knowing of most people - often linked to Oracle RAC and therefore, is rarely used to implement failover solutions. 11gR2 Clusterware – which is part of Oracle Grid Infrastructure - provides a comprehensive framework to setup automatic failover configurations. It is actually possible to make “failover-able'” and, therefore to protect, almost every kind of application (from xclock to the more complex Application Server) In the next couple of lines, I will try to present the different steps to achieve this goal : Have a fully operational 11gR2 database protected by automatic failover capabilities. I assume you are fluent in installing Oracle Database 11gR2, Oracle Grid Infrastructure 11gR2 on a Linux system and that ASM is not a problem for you (as I am using it as a shared storage). If not, please have a look at Oracle Documentation. As often, I made my tests using an Oracle VirtualBox environment. The scripts are tested and functional. Unfortunately, there can always be a typo or a mistake. This blog entry is not a course around the Clusterware Framework. I just hope it will let you see how powerful it is and that it will give you the whilst to go further with it…   Prerequisite 2 Linux boxes (OELCluster01 and OELCluster02) at the same OS level. I used OEL 5 Update 5 with Enterprise Kernel. Shared Storage (SAN). On my VirtualBox system, I used Openfiler to simulate the SAN Oracle 11gR2 Database (11.2.0.1) Oracle 11gR2 Grid Infrastructure (11.2.0.1)   Step 1 – Install the software Using asmlib, create 3 ASM disks (ASM_CRS, ASM_DTA and ASM_FRA) Install Grid Infrastructure for a cluster (OELCluster01 and OELCluster02 are the 2 nodes of the cluster) Use ASM_CRS to store Voting Disk and OCR. Use SCAN. Install Oracle Database Standalone binaries on both nodes. Use asmca to check/mount the disk groups on 2 nodes Use dbca to create and configure a database on the primary node Let’s name it DB11G. Copy the pfile, password file to the second node. Create adump directoty on the second node.   Step 2 - Setup the resource to be protected After its creation with dbca, the database is automatically protected by the Oracle Restart technology available with Grid Infrastructure. Consequently, it restarts automatically (if possible) after a crash (ex: kill –9 smon). A database resource has been created for that in the Cluster Registry. We can observe this with the command : crsctl status resource that shows and ora.dba11g.db entry. Let’s save the definition of this resource, for future use : mkdir –p /crs/11.2.0/HA_scripts chown oracle:oinstall /crs/11.2.0/HA_scripts crsctl status resource ora.db11g.db -p > /crs/11.2.0/HA_scripts/myResource.txt Although very interesting, Oracle Restart is not cluster aware and cannot restart the database on any other node of the cluster. So, let’s remove it from the OCR definitions, we don’t need it ! srvctl stop database -d DB11G srvctl remove database -d DB11G Instead of it, we need to create a new resource of a more general type : cluster_resource. Here are the steps to achieve this : Create an action script :  /crs/11.2.0/HA_scripts/my_ActivePassive_Cluster.sh #!/bin/bash export ORACLE_HOME=/oracle/product/11.2.0/dbhome_1 export ORACLE_SID=DB11G case $1 in 'start')   $ORACLE_HOME/bin/sqlplus /nolog <<EOF   connect / as sysdba   startup EOF   RET=0   ;; 'stop')   $ORACLE_HOME/bin/sqlplus /nolog <<EOF   connect / as sysdba   shutdown immediate EOF   RET=0   ;; 'check')    ok=`ps -ef | grep smon | grep $ORACLE_SID | wc -l`    if [ $ok = 0 ]; then      RET=1    else      RET=0    fi    ;; '*')      RET=0   ;; esac if [ $RET -eq 0 ]; then    exit 0 else    exit 1 fi   This script must provide, at least, methods to start, stop and check the database. It is self-explaining and contains nothing special. Just be aware that it is run as Oracle user (because of the ACL property – see later) and needs to know about the environment. It also needs to be present on every node of the cluster. chmod +x /crs/11.2.0/HA_scripts/my_ActivePassive_Cluster.sh scp  /crs/11.2.0/HA_scripts/my_ActivePassive_Cluster.sh   oracle@OELCluster02:/crs/11.2.0/HA_scripts Create a new resource file, based on the information we got from previous  myResource.txt . Name it myNewResource.txt. myResource.txt  is shown below. As we can see, it defines an ora.database.type resource, named ora.db11g.db.

Once done, we can revert back to the original node, but, this time we can use a more “MS$ like” method :Turn off the server on which the database is running. After short delay, you should observe that the database is relocated on node 1. Conclusion Once the software installed and the standalone database created (which is a rather common and usual task), the steps to reach the objective are quite easy : Create an executable action script on every node of the cluster. Create a resource file. Create/Register the resource with OCR using the resource file. Start the resource. This solution is a very interesting alternative to licensable third party solutions.   References Clusterware 11gR2 documentation Oracle Clusterware Resource Reference   Gilles Haro Technical Expert - Core Technology, Oracle Consulting

  • Getting Internal Name of a Share Point List Fields

    - by Gino Abraham
    Over the last 2 weeks i was developing a tool to migrate Lotus notes data base to Share point. The mapping between Lotus notes schema and share point list schema was done manually in an xml file for out tool. To map the columns we wanted internal names of each field. There are quite a few ways to achieve this, have explained few below. If you want internal names for one or 2 columns you can do so by navigating to the list setting and clicking on the column name. Once you are in column's details, you can check the query string of the page. The last item in the query string would be field's internal. Replace all "%5f" with '_' will give you the field internal name. In my case there were more than 80 columns. I used power shell to get the list of columns with details. Open windows Powershell and paste the following script after modifying the url and list name. [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint") $site = new-object Microsoft.SharePoint.SPSite(http://yousitecolurl) $web = $site.OpenWeb() $list = $web.Lists["yourlist name"] $list.Fields | Format-Table Title, InternalName, TypeAsString I also found a tool in Codeplex.com which can generate a wrapper class for a list. The wrapper class will give you the guid and internal name for all fields in the list.  You can download the tool from http://imtech.codeplex.com/ Just enter the url in the text box and hit open. All the site content will be listed at the left hand side, expand the list, right click and select generate wrapper class.

  • Problem opening XWindows programs with xming and SSH Secure Shell

    - by Brian
    I've installed SSH Secure Shell and xming on my laptop running Windows 7 (64-bit). I'm having trouble starting X Windows applications from the SSH console. I've been able to do it in the past. I've pretty much determined that it's not a server issue because I've tried it on two different servers (both servers are running RHEL 5). Running "echo $DISPLAY" on either server gave me "localhost:10.0". My XLaunch configuration settings are: Multiple Windows, 10 (display number), and Start no client. Once xming has launched, I'll try to execute something like "firefox" and I get this back: The application 'firefox' lost its connection to the display localhost:10.0; most likely the X server was shut down or you killed/destroyed the application. I've already checked to make sure that the X server is running and it is: root 12579 2689 0 Feb14 tty7 00:04:23 /usr/bin/Xorg :0 -br -audit 0 -auth /var/gdm/:0.Xauth -nolisten tcp vt7 Additionally, X11 Tunneling has been enabled in SSH as well as SSH 2 connections.

  • How to backup/restore OSX Parental Controls before/after complete reimage?

    - by Jim Anderson
    We typically "nuke and pave" users Mac OSX laptops if they have software issue. Prior to doing so, we backup the primary (non-admin) user's home folder. Our standard image has four accounts: Admin (uber admin user); Parent (admin account for the parents of students); Loaner (so our standard image will also work for our loaner laptop pool); Student (this is the primary, non-admin user of the laptop) Our standard image has only minimal Parental controls on the Loaner and Student accounts. Some parents choose to tighten the parental controls. We never know when parents have made changes to parental controls, or what those changes are. Once we have reimaged the machine with our standard image (minimal parental controls) we would like to be able to restore any custom parental controls parents may have placed on their student's account. Any help in this would be appreciated. Thanks.

  • Google Analytics checkout page tracking problem

    - by Amir E. Habib
    I am running a multilingual website, each lang on a different domain name. I am trying to lead all purchase requests to the checkout progress, which has its own domain too. In order to keep Google Analytics tracking I've updated the Google Analytics code accordingly. I set the source domain to 'multiple top-level domains'. Everything is going fine so far unless in E-commerce Overview; the "Sources / Medium" is always showing as (direct) - or the name of the source domain. Since I am redirecting using PHP header(location:.. etc.) the Google _link method doesn't seem to be working properly - I want to focus on two questions: Should I create a new profile for the checkout domain in Google Analytics? (I am now using the profile ID of the source domain even though I move to the checkout domain, si that OK?) When I'm trying to pass the cookies of the source domain to the checkout domain, I notice that the Google cookies are copied to the new domain (the cookie path is .checkout-domain/) and they have the same values of the original cookies - But for some reason another set of cookies is created once I access a page with google analytics code in the checkout pages, with different values (same path). Feels like I'm doing something wrong here, so my question is - What am I doing wrong here? Does anyone have an idea how to pass the cookies to the checkout domain?

  • NETAPP Fragmentation

    - by mdpc
    We all know that once a disk (or storage system for that matter) gets introduced into use, the performance degrades due to fragmentation of files. This seems to be why disk defragmentors are in fairly wide use on Windows boxes. And they do increase the performance substancially. As an aside, I haven't heard of many defragmentors in the Unix/Linux area. Despite the claimed WAFL protections for the NetApp, file fragmentation still will occur, especially with all the sparsely crated VMs. My question is does anybody do any sort of defragmention of such a storage system? Do you notice any measurable degration/improvement of either not doing/doing anything to address this situation? Does anybody do anything about it? If so what? Thanks

  • Black screen appears when booting new install of 11.10 on my desktop, cannot access Grub menu to fix

    - by Cee
    I installed 11.10 on my desktop PC but get a black screen after the BIOS screen when I try to boot it. I was able to run 10.04.04 on my hard drive before installing 11.10 and I am also able to use 11.10 on my usb pendrive and CD ROM. I've tried unplugging all USB devices before booting and also upgrading from 11.10 to 11.10. Holding the shift key from the BIOS screen doesn't allow me to access the GRUB menu to try: Highlight the first entry, press “e” to edit it. Navigate to words “quiet splash”, delete them and type “nomodeset” in their place (without quotes). Press Ctrl + X to continue boot. Once on the desktop, go to System Administration Additional Drivers and activate the recommended drivers. So running 11.10 on my pendrive, I tried editing /etc/default/grub, commenting out the GRUB_HIDDEN_TIMEOUT setting by putting a '#' in front of it to display the grub menu and setting GRUB_TIMEOUT setting to a value greater than or equal to 1 e.g. GRUB_TIMEOUT=10. However, when I run sudo update-grub, I get: /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?) I get the same error with update-grub after: sudo mount /dev/sda1 /mnt and after: sudo grub-install --root-directory=/mnt /dev/sda reboot sudo update-grub Other suggestions to fix the update-grub problem: Open synaptic, then purge all the related grub installed packages and reinstall grub-pc then and finally: sudo update-grub Or use Grub Customizer http://ubuntuforums.org/showthread.php?t=1195275 What would be the best way to approach this? I'm concerned about purging "all the related grub installed packages" but if it's true some files are corrupted this would seem necessary. Also, was I executing the correct commands i.e. with mount and grub-install, before running grub-update?

  • Script / command to drop all connections / locks in Sybase SQL Anywhere 9?

    - by nxzr
    I've recently become responsible for administering an application which is essentially a front end to a Sybase SQL Anywhere 9 database, including the database itself. I'd like to use unload table to efficiently export the data for backup and, in the case of a few tables, ETL to get it into a reporting database / small scale data warehouse. The problem is that the client application crashes and leaves dead connections and shared locks on a pretty regular basis, which seems to prevent unload table from getting the (brief) exclusive locks it needs. Currently I use Sybase Central to verify that these connections are in fact zombies and drop them myself at the end of the day / week. Is there a command or script to drop all connections? Being able to drop everything at once after verifying that they're unneeded would be quite helpful but I haven't found a way to do it.

  • Installing Windows on HP Proliant Servers without SmartStart

    - by Fitzroy
    I have a PXE server for deploying Windows XP and Windows 7 to workstations. The process is as follows: Boot the workstation from the NIC. Workstation sends a DHCP request. DHCP server responds with an IP address and the location of the PXE server. Workstation downloads WinPE image file from PXE server via TFTP Workstation stores WinPE image file in memory and executes it. Once booted into WinPE, I connect to a network share to gain access to either the Windows XP or Windows 7 installation files. A custom script is launched to guide you through the process of formatting and partitioning the hard drive(s) (using DISKPART and FORMAT). Another custom script asks for details such as the hostname to assign to the workstation. The answers provided are used to build an unattended answer file (SIF [Setup Information File] for WinXP and XML for Win7). The Windows setup EXE is launched, passing the unattended answer file to it as a parameter. The Windows XP and Windows 7 installation sources have been customised to include the drivers for our Dell workstations. They also run a number of scripts upon first booting up to install software packages. This process works very well for our workstations and I would now like to use it for building our servers too. The vast majority of our servers are HP Proliant DL360 G6, DL380 G5 and DL380 G6. They’re running Windows Server 2003 (various editions) or 2008 (various editions). To date, we have always built the HP Proliant servers using the SmartStart CD provided. SmartStart does three useful things for us: Setup RAID with HP Array Configuration Utility (ACU). Installs and configures SNMP Installs various HP Tools for Windows (HP Array Configuration Utility, HP Array Diagnostic Utility, HP Proliant Integrated Management Log Viewer, etc) Using SmartStart I have never had to manually download and install Windows drivers for network, sound, video, etc. I'm not sure if this is because SmartStart copies drivers from the CD during setup, or whether Windows just has the drivers natively in its driver CAB. If I abandon the SmartStart CD in favour of my PXE server I would have to do the following: As I wont have access to ACU, I'll configure the RAID (before booting to the PXE server) by pressing F8 (during the boot process) to access Option ROM Configuration for Arrays (ORCA). Installation of SNMP and the HP Tools will have to be installed once the Windows installation is complete using the Proliant Support Pack. Is this method OK? Is there anything that the SmartStart CD does that I'll be unable to do by other means? Are there any disadvantages to not using the SmartStart CD? Many thanks. UPDATE 05/01/12 I’ve been reading through the SmartStart Scripting Toolkit documentation. The scripting toolkit contains command line tools which work within WinPE and can such things as configure BIOS settings, configure an array and setup ILO. I’m personally not too bothered about configuring BIOS settings as I rarely deviate from the defaults (unless the server is to be a Hyper-V host). I’m not too fussed about being able to configure the array from within WinPE, as I’m happy to just press F8 and use Option ROM Configuration for Arrays (ORCA). Although, if it’s easy enough to do, I will explore this further, as it saves time if everything can be configured from within WinPE. One of the nice features all the tools possess is that you can pass input files to them. EG. Configure one server to your requirements, capture its configuration to a file (using the appropriate tool), you can then use the tool on other servers passing the input file with the captured configuration. Array controller drivers appear to be included with the toolkit along with example of how to incorporate them within a WinPE build. I suppose WinPE won’t be able to see logical volumes (I.E 2x physical disks in a RAID 1 configuration) without the array controller drivers? I mentioned in my post that SmartStart normally installs a bunch of Windows HP tools for you. I’ve had a look today, and if you run the SmartStart CD from within Windows all the tools can be installed. Therefore I can do this after the Windows installation is complete. The SmartStart CD appears to contain a lot Windows drivers. I can customise my Windows 2008 source to incorporate these drivers. However, I understand that incorporating an array controller driver is a little different to most drivers. I believe that you have to provide the driver during the very early stages of the Windows setup. I’m working through the Scripting Toolkit documentation to try and work this out...

  • backing up a virtual machine

    - by ErocM
    I inquired with the support of justcloud.com telling them that I have a vmware vm that I was wondering if it could be backed up while in use. I can back up the vm once it is shut down but I was wondering if their "shadow copy" would back it up while running. This was their response: Thank you for your email. I am really very sorry but virtual machines can't be backed up for a simple reason that they are virtual, they have virtual memory, not physical memory. Please let me know if there is anything else I can help with. Kind Regards, Barry James User Experience Team www.justcloud.com These are physical files so I wasn't sure I even understood the response. Am I wrong in thinking that a vm can be backed up while in use? Does this response even make sense? I need a cheap alternative to backing up the vm off the server in case it goes down. Any suggestions?

  • Should these concerns be separated into separate objects?

    - by Lewis Bassett
    I have objects which implement the interface BroadcastInterface, which represents a message that is to be broadcast to all users of a particular group. It has a setter and getter method for the Subject and Body properties, and an addRecipientRole() method, which takes a given role and finds the contact token (e.g., an email address) for each user in the role and stores it. It then has a getContactTokens() method. BroadcastInterface objects are passed to an object that implements BroadcasterInterface. These objects are responsible for broadcasting a passed BroadcastInterface object. For example, an EmailBroadcaster implementation of the BroadcasterInterface will take EmailBroadcast objects and use the mailer services to email them out. Now, depending on what BroadcasterInterface implementation is used to broadcast, a different implementation of BroadcastInterface is used by client code. The Single Responsibility Principle seems to suggest that I should have a separate BroadcastFactory object, for creating BroadcastInterface objects, depending on what BroadcasterInterface implementation is used, as creating the BroadcastInterface object is a different responsibility to broadcasting them. But the class used for creating BroadcastInterface objects depends on what implementation of BroadcasterInterface is used to broadcast them. I think, because the knowledge of what method is used to send the broadcasts should only be configured once, the BroadcasterInterface object should be responsible for providing new BroadcastInterface objects. Does the responsibility of “creating and broadcasting objects that implement the BroadcastInterface interface” violate the Single Responsibility Principle? (Because the contact token for sending the broadcast out to the users will differ depending on the way it is broadcasted, I need different broadcast classes—though client code will not be able to tell the difference.)
