• Dude, where is my list instance?

  - by MOSSLover

  I saw an MSDN Forum post today, so I looked for a ListInstance Hidden property in SharePoint 2007 features.  There is none, but interestingly enough there is one in 2010.  I wondered what would happen if you did this: <Elements xmlns="http://schemas.microsoft.com/sharepoint/">   <ListInstance            FeatureId="00bfea71-de22-43b2-a848-c05709900100"            Title="Hidden List Test"            Description="Testing a hidden list."            TemplateType="100"            Hidden="TRUE"            OnQuickLaunch="FALSE"            Url="Lists/TestHidden" /> </Elements> It hides the entire list from SharePoint Designer and the browser, however you can hit the list by typing in the url in internet explorer.  Pretty cool stuff.  Enjoy guys.

• When to mark a user story as done in scrum?

  - by Saeed Neamati

  There is a notion in scrum that emphasizes delivery of workable units at the end of each sprint. Each workable unit also maps directly of indirectly to a user story and when in new sprint PO introduces new PBI (new user stories), this means that practically team can't always go back to previous user stories to do the rest of the job, which in turn means that when you implement a user story, you should do it as complete as it's known to the team in that time, and you shouldn't forget anything (something like "I'm sorry, I've forgotten to implement validation for that input control" or "I didn't know that cross-browser check is part of the user story"). At the other hand, test, backward compatibility, acceptance criteria, deployment and more and more concepts come after each user story. So, when can team members know that the user story is done completely, not just for demo, and start a new one?

• Resolution independent physics

  - by user46877

  I'm making a game like Doodlejump but don't know how to make the physics scale on multiple resolutions. I also can't find anything related to this on Google. Right now I'm scaling the game using letterboxing and tested scaling the jump height with this code: gravity = graphics.getHeight() * 0.001f; jumpVel = graphics.getHeight() * -0.04f; ... velY += gravity; y += velY; But if I test this on my smartphone or emulator with different resolutions, I always get a slightly different jump height. I know that Farseer is resolution independent. How can I replicate this in my game? Thanks in advance.

• SharePoint 2010 Information Worker VM available for download

  - by Enrique Lima

  If you interested in a test drive of the technologies around the Wave 14 launch, take look at the VM made available from Microsoft. It is a very well rounded option to explore the new products. 2010 Information Worker Demonstration and Evaluation Virtual Machine Note:  It is important to understand you will need a system with Hyper-V to import this VM and get it off and working.  Also, make sure you keep a copy of the original unpacked VM as this is based on a trial version of the OS (time bombed) and there is a chance to rearm the VM, but you are better off either keeping the original files or taking a snapshot as soon as the VM is living in your Hyper-V environment.

• Useful code paste site tools

  - by acidzombie24

  I know there are site tools to check if your webpage is alive, has compression, etc but lets not get into that. What are useful sites to paste code in and to share links of? The three i know are http://codepad.org/ shows source and runs code online http://www.pastie.org/ share source with syntax highlighting http://jsfiddle.net/ great for JS help or for the occasional test. What else do you know of? One answer per question. I'll let lints and validators slide since you do paste code into them. Mention a weakness if you do know one so others wont be surprised or disappointed.

• Is it more difficult to upgrade your certification from SQL Server 2008 to 2012 than to get it from scratch?

  - by Diego

  I was wondering about the new MCSA certification on SQL 2012 and how it seems to be more difficult to upgrade your certification from 2008 to 2012 than to get the 2012 from scratch. Reason I think that is true is because anyone with any MCTS SQL Server 2008 certification can upgrade it to a MCSA 2012 by passing 2 tests (457 and 458). If you try to get it from scratch, you need to pass 3 tests (461, 462 and 463 - which are pretty much the same as 432, 433 and 448 for SQL 2008). But the thing is, even though its one test less to upgrade, all the skills necessary to pass 461, 462 and 463 are squeezed on 457 and 458 so, it seems easier to get from scratch than upgrade. Any thoughts?

• Soda Cans Exploding Under the Stress of High Voltage [Video]

  - by Jason Fitzpatrick

  In an effort to start your Monday off in true Mad Scientist style, we bring you soda cans being decimated by thousands of volts in a “Thumper”. What is a thumper, you ask? During office hours, it’s a high-voltage testing unit most often used to stress test electric cables. In the off hours, however, the electrical engineering geeks over at The Geek Group like to shove anywhere from a few hundred to thousands of volts through unsuspecting objects to see what happens. In this installation they’re shooting high voltage through a variety of soft drink cans with an end result that sounds and looks like a cannon loaded with Mountain Dew.

• Protecting PDF files and XDO.CFG

  - by Greg Kelly

  Protecting PDF files and XDO.CFG Security related properties can be overridden at runtime through PeopleCode as all other XMLP properties using the SetRuntimeProperties() method on the ReportDefn class. This is documented in PeopleBooks. Basically this method need to be called right before calling the processReport() method: . . &asPropName = CreateArrayRept("", 0); &asPropValue = CreateArrayRept("", 0); &asPropName.Push("pdf-open-password"); &asPropValue.Push("test"); &oRptDefn.SetRuntimeProperties(&asPropName, &asPropValue); &oRptDefn.ProcessReport(&sTemplateId, %Language_User, &dAsOfDate, &sOutputFormat); Of course users should not hardcode the password value in the code, instead, if password is stored encrypted in the database or somewhere else, they can use Decrypt() api

• How to change default boot with two Ubuntus?

  - by d3vid

  I currently have 11.10 and 12.04 Beta running side-by-side. Since installing the beta, I am presented with a GRUB2 menu every time I boot up, which selects 12.04 by default. (Aside: when the 11.10 kernel updated from 3.0.0-16 to 3.0.0-17 this option did not appear in the GRUB2 menu.) When I open Grub Customizer in 11.10, it shows 11.10 kernel 3.0.0-17 as the default, when I open Grub Customizer in 12.04, it shows 12.04 as the default. How can I change GRUB2 to pick the latest 11.10 kernel as the default? (Latest means that if 3.0.0-18 is released it will become the default, and so on.) And also stop displaying the menu (I only boot into the beta when I have something specific to test). Generic answers that apply to any two Ubuntus running side-by-side are preferred.

• Permissions & File Structure w/ nginx & multiple sites

  - by Michael

  I am using nginx for the first time as a long time Apache user. I setup a Linode to test everything and to eventually port over my websites. Previously I had /home/user/www (wwwroot) I am looking at doing something similar with /srv/www/domain/www (wwwroot) Rather than using /srv/domain (wwwroot), the reason is many of the sites are WordPress and one of the things I do for security is to move the config file one level above wwwroot and can't have multiple configuration files from multiple domains in the same top level folder. Since I own all the sites, I wasn't going to create a user for each domain. My user is a member of www-data and was going to use 2770 for www and have domain/www for each new domain. www would be owned by group www-data. Is this the best way to handle this?

• Canon Mx772 printer recognized, drivers loaded...but all print jobs "Held"

  - by user212169

  BRAND NEW to Ubuntu but loving it so far. I have a Canon MX772 wireless printing running on my network and am able to print fine from a PC and Mac. Using the printers IP, Ubuntu was able to find it and I accepted all of the "recommended" items (it found a Canon MX770 driver). Everything seems to load fine...but the test page does not print, nor does any print commands make it to the printer. If I open the print dialogue jobs are shown as "held" and when I look at the jobs attributes, I see "Job printer state message=cannot specify model number" and then a few lines down "job state reasons=aborted by system". If I try to "resume" it immediately goes back to "held". I can successfully ping the IP of the printer. Would be very appreciative of other ideas...printing is the last check in the box before I am all set up. Thanks!

• Ping.eu

  - by Sarang

  Found an interesting resource thanks to a close friend. Ping.eu is a free service which would let you test various aspects related to networks which would typically be pain inducing doing it on your own. For seasoned network professional having a MAC address of their own instead of a name :) this might not be that useful. However for a layperson like me this an invaluable resource. These guys provide you with following services: Ping – Shows how long it takes for packets to reach host Traceroute – Traces the route of packets to destination host from our server DNS lookup – Look up DNS record WHOIS – Lists contact info for an IP or domain Port check – Tests if port is opened on specified IP Reverse lookup – Gets hostname by IP address Proxy checker – Detects a proxy server Mail relaying – Tests relaying capabilities of specified mail-server Bandwidth meter – Detects your download speed from our server Network calculator – Calculates subnet range by network mask Network mask calculator – Calculates network mask by subnet range Country by IP – Detects country by IP or hostname Unit converter – Converts values from one unit to another   Taken straight from their site. Thanks Ping.eu

• Scrum: How to work on one story at a time

  - by Juergen

  I was nominated as scrum master in a new formed scrum team. We have already done some sprints. In the beginning I tried to make my team to work on one story at a time. But it didn't work. My team had difficulties to distribute the tasks in a way that they can work simultaneously on one story. Maybe we are doing something wrong? For example: we have a story to create a new dialog. We create the following tasks: Create Model classes Read model data from database Connect model classes with view Implement dialog handling Save data on close Test Documentation Solution Description Can theses tasks be done by more than one person at a time? The tasks - more or less - build upon each other. Or do we design the tasks in a wrong way?

• Data binding directly to a store query (DbSet, DbQuery, DbSqlQuery) is not supported.

  - by Chandradev

  HiI was doing some test with code first approach in EF. Then while populating the Gridview i was getting error like thisData binding directly to a store query (DbSet, DbQuery, DbSqlQuery) is not supported. Instead populate a DbSet with data, for example by calling Load on the DbSet, and then bind to local data. For WPF bind to DbSet.Local. For WinForms bind to DbSet.Local.ToBindingList().For solving this error we have to write the code like this private void FillGrid()        {            using (var Context = new EmpDatabaseContext())            {                var query = Context.Emps.Select(m => m);                //var query = from m in Context.Emps                //            select m;               // Gridview1.DataSource = query;                Gridview1.DataSource = query.ToList();                Gridview1.DataBind();            }        }  We canot bind Iqueryable directly. We have to change into ToList()

• How to Multitask in the Linux Terminal: 3 Ways to Use Multiple Shells at Once

  - by Chris Hoffman

  The Linux terminal has rich multitasking capabilities. You can switch between the virtual consoles already running on your system, use Bash job control to run processes in the background, and take advantage of GNU screen, a terminal “window manager.” You don’t have to stick to a single command at a time. Whether you want to run a process in the background and revisit it occasionally or run multiple time-consuming tasks at once, Linux offers several options.

• Obtaining In game Warcraft III data to program standalone AI

  - by Slav

  I am implementing common purpose behavioral algorithm and would like to test it under my lovely Warcraft III game and watch how it will fight against real players. The problem is how to obtain information about in game state (units, structures, environment, etc. ). Algorithm needs access to hard drive and possibly distributed computing, that's why JASS (WC3 Editor language) usage doesn't solve the issue. Direct 3D hooking is an approach, but it wasn't done for WC3 yet and significant drawback is inability to watch online at how AI performs since it uses the viewport to issue commands. How in game data can be obtained to a different process in a fastest and easiest way? Thank you.

• Python C API return more than one value / object

  - by Grisu

  I got the following problem. I have written a C-Extension to Python to interface a self written software library. Unfortunately I need to return two values from the C function where the last one is optional. In Python the equivalent is def func(x,y): return x+y, x-y test = func(13,4) #only the first value is used In my C extension I use return Py_BuildValue("ii",x+y,x-y); which results in a tuple. If I now try to access the return value from Python via test2 = cfunc(13,4) print(test2) I got a tuple instead of only the first return value. How is possible to build the same behavior as in Python from C Extension?

• Alcatel-Lucent Boosts Broadband Over Copper To 300Mbps

  - by Ratman21

  alphadogg at Slashdot writes "Alcatel-Lucent has come up with a way to [0]move data at 300Mbps over copper lines. So far the results have only been reproduced in a lab environment — real products and services won't be available for at least a year. From the article: 'Researchers at the company's Bell Labs demonstrated the 300Mbps technology over a distance of 400 meters using VDSL2 (Very high bitrate Digital Subscriber Line), according to Stefaan Vanhastel, director of product marketing at Alcatel-Lucent Wireline Networks. The test showed that it can also do 100Mbps over a distance of 1,000 meters, he said. Currently, copper is the most common broadband medium. About 65 percent of subscribers have a broadband connection that's based on DSL, compared to 20 percent for cable and 12 percent for fiber, according to market research company Point Topic. Today, the average advertised DSL speeds for residential users vary between 9.2 Mbps and 1.9Mbps in various parts of the world, Point Topic said.'"

• ~/.bashrc return can only 'return' from a function or sourced script

  - by Timothy

  I am trying to setup a OpenStack box to have a look at OpenStack Object Storage (Swift). Looking through the web I found this link; http://swift.openstack.org/development_saio.html#loopback-section I followed the instructions line by line but stuck on step 7 in the "Getting the code and setting up test environment" section. When I execute ~/.bashrc I get; line 6: return: can only 'return' from a function or sourced script. Below is the Line 6 extract from ~/.bashrc. My first reaction is to comment this line out, but I dont know what it does. Can anyone help? #If not running interactively, dont't do anything [ -z "$PS1" ] && return I'm running Ubuntu 12.04 as a VM on Hyper-v if knowing that is useful.

• How does TDD address interaction between objects?

  - by Gigi

  TDD proponents claim that it results in better design and decoupled objects. I can understand that writing tests first enforces the use of things like dependency injection, resulting in loosely coupled objects. However, TDD is based on unit tests - which test individual methods and not the integration between objects. And yet, TDD expects design to evolve from the tests themselves. So how can TDD possibly result in a better design at the integration (i.e. inter-object) level when the granularity it addresses is finer than that (individual methods)?

• Screen Corruption in half the screen only

  - by Guy DAmico

  About 50% of the my NATTY desktop screen is corrupted. Once that happens I can re-boot as many times as I want but the problem continues. If I logout and then into WINDOWS for a day I may be successful and boot UBUNTU with a good screen. The desktop is formatted correctly, there's no pixelation, rather there is a fine grained white crosshatch pattern covering the entire screen. If I open any application the screen corruption worsens eventually to the point I can no longer make out anything. I ran ram memory test w/o any errors. I have no display issues when running WINDOWS 7. Any ideas. My computer is a Dual Boot stock DELL 5150 w/3gig of ram an on board video.
