  • DotNetNuke 7.0 Only Weeks Away!

    - by sbwalker
    The software industry moves at a lightning pace, and it is only through constant focus and continuous investment that a software product can remain both stable and relevant over the long term. As we approach the 10 Year Anniversary of the DotNetNuke platform, it seems only fitting that we are on the verge of announcing yet another significant product milestone. DotNetNuke 7.0 is just around the corner and represents a bold step forward for our Content Management Platform, including substantial business productivity enhancements, investments in web platform relevance, and a significant overhaul and modernization of the user interface and user experience. It has been five months since I posted the announcement that the next major version of the platform was going to be DotNetNuke 7.0.  This announcement created tremendous excitement and anticipation in the DotNetNuke community, as major version increments have always been utilized as an opportunity  to introduce revolutionary new product features and capabilities. After months of intense product development, the finish line is finally in sight. With that, I am pleased to announce that we released a Release Candidate (RC) of DotNetNuke 7.0 yesterday. You can download the RC from our project page on Codeplex. A Release Candidate represents a software version which is very near to “release” quality. So although we will not be officially endorsing the RC for production use, or providing an official upgrade path, it does represent a significant milestone in our software development efforts ( if you are looking for a more detailed explanation of our software release terminology, I would encourage you to read the blog written by Co-Founder, Joe Brinkman titled "What's In A Name?" ). Modernizing a software platform does have its share of challenges from a backward compatibility perspective and, as usual, we are taking great care in ensuring a seamless upgrade path for our customers. In order to remain relevant and progressive, you need to be aware that DotNetNuke 7.0 has adopted a new set of baseline infrastructure requirements including ASP.NET 4.0.  As a result we are encouraging all major stakeholders in the ecosystem ( module developers, designers, partners, customers, etc... ) to take the opportunity to install the RC in their own local environments. This is the last opportunity to let us know about any final issues which may need to be addressed prior to final release. Mark your calendars now… the expected public release date (RTM) for DotNetNuke 7.0 will be Wednesday, November 28th. On a side note, we expect to release a 6.2.5 Maintenance version today. This release contains some high priority product quality improvements as well as security patches for some vulnerabilities reported through our standard ecosystem channels. As a result we will be encouraging all of our customers to upgrade to the 6.2.5 release as soon as it is available. I hope everyone is as excited as I am about the upcoming DotNetNuke 7.0 release. Please take the opportunity over the next week to put the new platform through its paces. Remember, only through our collective efforts can we ensure that this release has the greatest market impact of any DotNetNuke release to date.

  • Inspiration

    - by Oracle Campus Blog
    Once again, I find myself back in Seoul – ASEM Tower, 16th Floor in a mobile room. I’m busy preparing for the interview process that is about to take place for Oracle Korea’s GIP 7th (Graduate Intake Program): scheduling the first round interviews, organizing interview guidelines, educating interviewers on the process and framework and  getting all the logistics ready for the 1st round interview. Seoul or Korea rather is a fascinating place. Highly efficient, the utmost respect for seniors and results orientated. When students come in for an interview at first it was hard to tell them apart – there seems to be accepted interview attire that must be worn when attending an interview. Males and Females, all dress in black suits, with white shirts underneath – with males to wear simple and dark colored ties. During the interview, they would all sit very upright, all would bow when entering the room, place their hands on the laps and very often they would hold minimal eye contact. They would project their voice loud to portray confidence, they would talk in the Korean formal dialect at all times and will treat every question, every moment with extreme clarity and the utmost professionalism. When the interview concludes, they will all stand hands by their sides, bow 90 degrees and thank all the interviewers for their precious time and opportunity. As soon as they leave the interview room, I could hear all their sighs of relief and commended each other on their efforts. More and more I learn about the Korean culture it inspires me. Their patriotism, their respect for each, their values, their appreciation, their motivation, their desires and passion – it truly was an experience for me (even as a recruiter) and can’t help but feel truly impressed and motivated to live for every moment.

  • Inconsistent movement / line-of-sight around obstacles on a hexagonal grid

    - by Darq
    In a roguelike game I've been working on, one of my core design goals has been to allow the player to "Play the game, not the grid." In essence, I want the player's positioning to be tactical because of elements in the game world, not simply because some grid tiles are more advantageous than others, in relation to enemies. I am fine with world geometry not being realistic, but it needs to be consistent. In this process I have ran into most of the common problems (Square tiles? Diagonal movement, LOS, corner cases, etc.) and have moved to a hexagonal tile grid. For the most part this has been great, and I've not had too many inconsistencies. Recently however I have been stumped by the following: Points A and B are both distance 4 from the player (red lines). Line-of-sight to both are blocked by walls (black tiles). However, due to the hexagonal grid, A can be reached in 4 moves, whereas B requires 5 moves (blue lines). On a hex grid, "shortest path" seems divorced from "direct path", there may be multiple shortest paths to any point, but there is only one direct path (or two in some situations). This is fine, geometry need not be realistic. However this also seems inconsistent, similar obstacles are more effective in some positions than in others. A player running away from an enemy should be able to run in any direction, increasing the distance between the two actors. However when placing obstacles or traps between themselves and enemies, the player is best served by running in one of the six directions that don't have multiple shortest paths. Is there a way to rationalise this? Am I missing something that makes this behaviour consistent? Or is there a way to make this behaviour consistent? I am most certainly over-thinking this, but as it is one of my goals, I should do it due diligence.

  • Ubuntu installation on iMac

    - by Shanew
    I have an iMac configured as follows - Screen 27" CPU 3.4 GHz i7 Graphics AMD Radeon HD 6970 1024 MB I downloaded Ubuntu version 11.10 64 bit ISO and burnt that to both DVD and USB stick as per the instructions on Ubuntu's download page. Neither will boot. Symptoms are as follows - DVD: When the iMac is restarted and booted from DVD (labelled Windows which isn't mentioned in Ubuntu's website instructions) one line is displayed against a black screen displaying a message about the developer and date. After 5 minutes the message hangs and the DVD ceases to spin. USB Stick: Strangely I have to select the EFI boot CD icon which appears after holding down the Alt key. A text menu appears offering me to try Ubuntu without installing. I select this and the screen goes blank and stays blank. Any ideas? Lastly, after writing Ubuntu to DVD and USB stick, neither could be read by OSX making the instructions to eject them as per Ubuntu website's instructions useless. This might help? Thanks, Shane.

  • Ubuntu 13.10 installed and worked, but now not working

    - by San
    I have a HP G7000 laptop. I updated/upgraded from 13.04 to 13.10, after the software updater recommended I upgrade. I have duel booting system with Windows Vista. The system was working for the past two days, but I start getting the errors below, after selecting Ubuntu in Grub Menu on startup and at the splash screen it says "Press S to Skip or M for manual configuration" Pressing S gives a black screen and m takes you the errors below. Windows boots and works fine after selection in the Grub Menu. [ 15.235703] EXT3-fs (sda5): error: unrecognized mount option "discard" or missing value. [ 16.788072] [drm:intel_pipe_config_compare] *ERROR* mismatch in adjusted_mode flags [expected 2, found 0] [ 20.860071] [drm:intel_pipe_config_compare] *ERROR* mismatch in adjusted_mode flags [expected 2, found 0] [ 20.980076] [drm:intel_pipe_config_compare] *ERROR* mismatch in adjusted_mode flags [expected 2, found 0] Root filesystem Check failed root@simamhar:~# Tried boot-repair using the LiveCD method, no luck. System still gives above error. (you can view the boot-repair log here http://paste.ubuntu.com/6287287) When I use the liveCD for 13.04 or 13.10 however, my hard disk is recognized and I can read the files. Why is it that the installation on the hard disk has stopped working and does not recognize my / ? What do the above errors mean and how can i solve them? There was no power failure before, during or after the update/upgrade process from 13.04 to 13.10. I now would like to go back to 13.04 without reinstalling afresh? Any help will be appreciated. Thanks.

  • Carriers Holding Your OS Updates Hostage

    - by Tim Murphy
    Originally posted on: http://geekswithblogs.net/tmurphy/archive/2013/10/10/carriers-holding-your-os-updates-hostage.aspx Just a small rant here.  Today the Windows Phone 8 GDR2 update finally became available for Nokia handset users.  Now I’m not sure that it is AT&T fault entirely that Samsung and HTC users got their updates two months ago and we are just finally seeing it.  It may have something to do with the Nokia Amber update.  But every Windows Phone update on AT&T from 7.1 on seems to have been delayed.  How is it that the premiere Windows Phone carrier is always the last one to release updates? Smart phone ecosystems are a partnership between the OS provider, the hardware manufacturer and the carriers.  If any one of those partners does not hold up its responsibilities then everyone gets a black eye.  The goal for all involved should be to release updates as early as possible with reasonable assurance of stability.  This ensures the satisfaction of consumers and increases the likelihood of future sales. From what I have seen so far AT&T has been the one breaking the consumer’s trust in the Windows Phone ecosystem.  Aside from voicing our dissatisfaction we may need to start voting with our feet until they realize that they being a poor citizen has consequences.

  • Algorithmically generating neon layers on pixel grid

    - by user190929
    In an attempt at a screensaver I am making, I am a fan of neo-like graphics, which, of course, look great against a black background. As I understand it, neon, graphically speaking, is essentially a gradient of a color, brightest in the center, and gets darker proceeding outward. Although, more accurate is similar, but separating it into tubes and glow. The tubes are mostly white, while the glow is where most of the color is seen. Well... the tubes could also be a light variant of the color, you could say. The glow is darker. Anyhow, my question is, how could you generate such things given an initial pattern of pixels that would be the tubes? For example, let's say I want to make a neon 'H'. I, via the libraries, can attain the rectangles of pixels which represent it, but I want to make it look neonized. How could I algorithmically achieve such an effect given a base tube shape and base color? EDIT: ok, I mistated that. Got a bit distracted. My purpose for this was similar to a neon effect, but not. Sorry about that. What I am looking for is something like this: Start with a pattern of pixels: [!][!][!][!][!][!][!][!] [!][!][O][!][!][!][!][!] [!][!][O][O][!][!][!][!] [!][!][!][!][O][!][!][!] [!][!][!][!][!][!][!][!] How to I find the U pixels? [!][E][E][E][!][!][!][!] [!][E][O][E][E][!][!][!] [!][E][O][O][E][E][!][!] [!][E][E][E][O][E][!][!] [!][!][!][E][E][E][!][!] Sorry if that looks bad.

  • Can't install Ubuntu on my Windows 7 laptop

    - by Ana
    I tried installing Ubuntu in two different ways: First, I tried the Windows Installer, and it goes well until I reboot the system and, when booting on Ubuntu, I get the error: No root file system defined. Second, I uninstalled wubi by going to to Control Panel - Uninstall Programs - Ubuntu. Then, I booted the laptop from the live CD and selected install. It boots okay but in the screen right after the one that says to make sure you have 4.5 GB available, Internet connection, etc, when I click continue it throws me a message saying that Ubuntu had an internal error and asks me if I want to report the error. After that, I just have a black screen and nothing else! No Ubuntu installed, no boot option to go back to Windows. Nothing! My goal is to install Ubuntu alongside Windows 7 (without the hassle of formatting the computer, creating partition, etc). How can I do it (preferable using Windows Installer)? How can I solve the "No root file system defined" that I encountered when I used the Windows Installer?

  • Flash player stops working in Firefox

    - by Alin
    First of all please be merciful as I am a 2 days ubuntu user. I've only used Windows OSs before. Hardware configuration -Quad Core Q6600 CPU -4 GB RAM -Geforce 8800GT 512 MB RAM -Seagate 320GB Harddisk I installed ubuntu x64 and everything went smooth. I had Adoble flash player installed from Ubuntu Software Center. The problem is that the flash videos on youtube (basically on all pages) looked pixelate. I use Firefox 3.6 that came with ubuntu by default. After reading around here I saw something about overriding hardware acceleration but that didn't work either. Or maybe I just didn't do it correctly. The problem was that if I opened 2-3 youtube tabs, when closing one of them, in 95% of the cases, the flash plugin would crash in remaining tabs and a black screen was instead of the video. After doing some more search I discovered the FlashAid extension for Firefox. I installed it and it made an update of flash plugin. Now the videos look good but now each time I watch a video, when switching to another one the flash plugin crashes and I can see insead of the vide the firefox message with Plugin has crasshed, refresh the page. Basically this is what I miss to have a complete pleasant ubuntu experience. Any ideas how to fix this? Thank you

  • Dissing Architects, or "What's wrong with the coffee?"

    - by Bob Rhubart
    In my conversations with people in architect roles, tales of animosity, disrespect, and outright hostility aren't uncommon. And it's clear that in more than a few organizations architects regularly face a tough uphill climb. For architects with the requisite combination of technical, organizational, and people skills, that rough treatment is grossly undeserved. But tales of unqualified people in positions up and down the IT food chain are also easy to come by. So what's the other side of the architect story? Are some architects tarnishing the role and making life miserable for their more qualified colleagues? The various quotes included below were culled from a variety of sources. The criticism is harsh, and the people behind these quotes clearly have issues with architects. Still, whether based on mere opinion or actual experience, the comments shed some light on behaviors that should raise red flags for anyone pursuing a career as an architect. If you're an architect, and you've ever noticed that your coffee tastes like window cleaner, or your car is repeatedly keyed, or no one ever holds the elevator for you, maybe you need to do a little soul searching... Those Who Can, Code; Those Who Can't, Architect | Joe Winchester [May 18, 2007] "At the moment there seems to be an extremely unhealthy obsession in software with the concept of architecture. A colleague of mine, a recent graduate, told me he wished to become a software architect. He was drawn to the glamour of being able to come up with grandiose ideas - sweeping generalized designs, creating presentations to audiences of acronym addicts, writing esoteric academic papers, speaking at conferences attended by headless engineers on company expense accounts hungrily seeking out this year's grail, and creating e-mails with huge cc lists from people whose signature footer is more interesting than the content. I tried to re-orient him into actually doing some coding, to join a team that has a good product and keen users both of whom are pushing requirements forward, to no avail. Somehow the lure of being an architecture astronaut was too strong and I lost him to the dark side." Don't Let Architecture Astronauts Scare You | Joel Spolsky [April 21, 2001] "It's very hard to get them to write code or design programs, because they won't stop thinking about Architecture. They're astronauts because they are above the oxygen level, I don't know how they're breathing. They tend to work for really big companies that can afford to have lots of unproductive people with really advanced degrees that don't contribute to the bottom line. Remember that the architecture people are solving problems that they think they can solve, not problems which are useful to solve." Non Coding Architects Suck | Richard Henderson [May 24, 2010] "If a guy with a badge saying 'system architect' looks blank on low-level issues then he is not an architect, he is a business-analyst who went on a course. He will probably wax lyrical on all things high-level and 'important.' He will produce lovely object hierarchies without a clue to implementation. He will have a moustache and play golf." Architects Play Golf | Sunir Shah [August 15, 2012] "Often arrogant architects are difficult to get a hold of during the implementation phase because they no longer feel the need to stick around. Especially around midnight when most of the poor sob [sic] developers are still banging away. After all, they've already solved the problem--the rest is just an implementation exercise." Engineer vs Architect(Part of a discussion on the IT Architect Network Group on LinkedIn) "[An] architect spends his time producing white papers full of acronyms he does not understand but that impress his boss [while the] engineer keeps his head down and does the actual job." Architects Don't Code | [Author Unknown] "Faulty belief: System Architects don't need to code anymore. They know what they are talking about by virtue of the fact that they are System Architects."

  • How do I install FreeNX server so that it works correctly?

    - by Niklas
    I've tried every single possible way of installing the server now, I've read every how to available and I still can't get it to work. Please let me know in which step I do wrong. I'm using ubuntu 10.10. I will mainly be referring to the following how-to, but also this, and this one. First I add the ppa Install Freenx Download the special Freenx package as stated in the howto, fix ownership - install it Create custom SSH key Copy the file /var/lib/nxserver/home/.ssh/client.id_dsa.key to the client and import it in nomachine (windows 7 x64) Check that both the user I will be logging in with and the user nx is in AllowedUsers in the /etc/ssh/sshd_config file Check the port that ssh is listening on Login through nomachine with my regular user account in ubuntu I always receive the message "authentication failed for [user]" when I try to log in. And I can't see the user "nx" which is said to be created during installation when I look under System-Administration-"Users & Groups". Can anyone please enlighten me if there is any step that I miss or have misunderstood? Thank you very much! (Or is there an easier way of enabling remote desktop that it can be used with a windows machine? I prefer not using VNC because I was hoping of being able to get better performance than that. And when I tried using XRDP I only received a black screen on the client.)

  • Unity's gone! How do I get it back?

    - by Kelley
    Earlier today my Unity desktop disappeared: I got a black screen with white text, but it disappeared too quickly for me to read. When the desktop reappeared, it was the Ubuntu Classic desktop. I used $ unity --reset but that did not do anything. I tried rebooting so I could choose unity from the list when I logged in, but although there was Ubuntu choice, there was no unity listed (but classic was listed). I was able to install Unity 2D and am using that, but really want to get 3D back. I had been using Ubuntu without problems for several weeks when this happened. My graphics card is onboard a Dell Latitude desktop - a couple years old - and is reported as an Intel G33/G31. I've looked at other requests for help here, and tried suggestions when they seemed to relate to similar problems, but nothing seems to work so far. Any ideas? Thanks!

  • Ubuntu 14.04 ATI Radeon open source driver with distorted video playback

    - by Bwog
    Video in VLC or SMplayer is often in black and white with washed-out colors in the wrong place (translated considerably). Moreover, the last video image is often visible when a new video is started and persist as long as the new video is running. Colors have a recognizable shape (e.g. a persons clothes or face), but can be obviously incorrect (e.g. green or purples faces). This is independent of the format of the videos (mp4, mkv, wmv). Sometimes all problems disappear when a new video is started, but often only a reboot restores normal video. Ubuntu was upgraded to 14.04 and is fully updated.

  • Getting rid of Massive View Controller in iOS?

    - by Earl Grey
    I had a discussion with my colleague about the following problem. We have an application where we need filtering functionality. On any main screen within the upper navigation bar, there is a button in the upper right corner. Once you touch that button, an custom written Alert View like view will pop up modally, behind it a semitransparent black overlay view. In that modal view, there is a table view of options, and you can choose one exclusively. Based on your selection, once this modal view is closed, the list of items in the main view is filtered. It is simply a modally presented filter to filter the main table view.This UI design is dictated by the design department, I cannot do anything about it so let accept this as a premise. Also the main filter button in the navbar will change colours to indicate that the filter is active. The question I have is about implementation. I suggested to my colleague that we create a separate XYZFilter class that will be an instance created by the main view controller acquire the filtering options handle saving and restoration of its state - i.e. last filter selected provide its two views - the overlay view and the modal view be the datasource for the table in its modal view. For some unknown reason, my colleague was not impressed by that approach at all. He simply wants to do these functionalities in the main view controller, maybe out of being used to do this in the past like that :-/ Is there any fundamental problem with my approach? I want to keep the view controller small, not to have spaghetti code create a reusable component (for use outside the project) have more object oriented, decoupled approach. prevent duplication of code as we need the filtering in two different places but it looks the same in both.. Any advice?

  • Restrict Tile Map to its boundaries

    - by Farooq Arshed
    I have loaded a tmx file in cocos2dx and now I am trying to implement panning. I have successfully implemented the panning first part where the map moves. Now I want to restrict the map so it does not display the map beyond its boundary where it shows black screen. I am confused as to how to implement it. Below is my code any help would be appreciated. bool HelloWorld::init() { if ( !CCLayer::init() ) { return false; } const char* tmx= "isometric_grass_and_water.tmx"; _tileMap = new CCTMXTiledMap(); _tileMap->initWithTMXFile(tmx); this->addChild(_tileMap); this->setTouchEnabled(true); return true; } void HelloWorld::ccTouchesBegan(CCSet *touches, CCEvent *event){ CCSetIterator it; for (it=touches->begin(); it!=touches->end(); ++it){ CCTouch* touch = (CCTouch*)it.operator*(); CCLog("touches id: %d", touch->getID()); oldLoc = touch->getLocationInView(); oldLoc = CCDirector::sharedDirector()->convertToGL(oldLoc); } } void HelloWorld::ccTouchesMoved(CCSet *touches, CCEvent *event) { if (touches->count() == 1) { CCTouch* touch = (CCTouch*)( touches->anyObject() ); this->moveScreen(touch); } else if (touches->count() == 2) { this->scaleScreen(touches); } } void HelloWorld::moveScreen(CCTouch* touch) { CCPoint currentLoc = touch->getLocationInView(); currentLoc = CCDirector::sharedDirector()->convertToGL(currentLoc); CCPoint moveTo = ccpSub(oldLoc, currentLoc); moveTo = ccpMult(moveTo, -1); oldLoc = currentLoc; this->setPosition(ccpAdd(this->getPosition(), ccp(moveTo.x, moveTo.y))); }

  • Minecraft in jdk 1.7.0_u2 x64

    - by Nela Drobná
    I have Ubuntu 11.10 64-bit and I installed JDK 1.7.0 update 2 x64 via webupd8 page. But currently I have problem with minecraft game. After downloading launcher from Minecraft.net and lauch the game by java -jar /home/zrebec/Downloads/minecraft.jar launcehr is launched normaly, after login the game download the updates but then I got just the black screen with this in terminal: Setting user: zrebec, -356009615199623309 Exception in thread "Minecraft main thread" java.lang.UnsatisfiedLinkError: /home/zrebec/.minecraft/bin/natives/liblwjgl.so: /home/zrebec/.minecraft/bin/natives/liblwjgl.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch) at java.lang.ClassLoader$NativeLibrary.load(Native Method) at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1928) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1825) at java.lang.Runtime.load0(Runtime.java:792) at java.lang.System.load(System.java:1059) at org.lwjgl.Sys$1.run(Sys.java:69) at java.security.AccessController.doPrivileged(Native Method) at org.lwjgl.Sys.doLoadLibrary(Sys.java:65) at org.lwjgl.Sys.loadLibrary(Sys.java:81) at org.lwjgl.Sys.<clinit>(Sys.java:98) at org.lwjgl.opengl.Display.<clinit>(Display.java:132) at net.minecraft.client.Minecraft.a(SourceFile:180) at net.minecraft.client.Minecraft.run(SourceFile:648) at java.lang.Thread.run(Thread.java:722) Please anyone can help me with this? I think that problem will be in architecture becase: liblwjgl.so: /home/zrebec/.minecraft/bin/natives/liblwjgl.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch) Any idea please? I know, maybe this one is off topic because maybe its not Ubuntu problem maybe but in 64-bit works all perfectly and I think that accepted answer can help to many users and can make better playing games under linux. Really. Thank you very much for any idea.

  • Unable to install Ubuntu 12.04.1 on Virtualbox on Windows 7 Host

    - by arcube
    I would like to install Ubuntu 12.04.1 in a virtual box on windows 7 host however I get a black screen after selecting to install Ubuntu i.e. right after choosing English language I have tried the 32bit and 64bit version desktop version, have also read thru some guides e.g. http://www.psychocats.net/ubuntu/virtualbox but I could not find any solution to fix this problem. BTW I have Ubuntu installed using Virtual PC (not running at the same time), also I have mac OS (mountain lion) installed using Virtual Box so I do not think it is a problem with the virtual box or windows 7 host. My VM configuration is with 1 core and 1 GB of ram using 20GB VDI; rest is default config. My hardware is Core i7 3770k / Asus P8Z77-V Deluxe / GSkill 32GB which I believe should be more than sufficient to run another VM. I have moved my user profile from SSD to HDD via junction however IMHO it should not matter. Has anyone else come across this problem and found a solution? Any help/thoughts on how to solve this would be very much appreciated.

  • The spork/platypus average: shameless self promotion

    - by Roger Hart
    This is the video of presentation I gave at UA Europe and TCUK this year. The actual sub-title was "Content strategy at Red Gate Software", but this heading feels more honest. For anybody who missed it, or is just vaguely interested, here's a link to me talking about de-suckifying the web. You can find the slideshare deck here, too* Watching it back is more than a little embarrassing, and makes me really, really want to do a follow up, so I can do three things: explain the rest of the big web project, now we've done it give some data on the outcome of the content review make a grovelling apology to our marketing guys, who I've been unfairly mean to in a childish effort to look cool There are a whole bunch of other TCUK presentations online, too. You can find them all here: http://tiny.cc/tcuk10_videos I'd particularly recommend Chris Atherton's: "Everything you always wanted to know about psychology and technical communication" - it's full of cool stuff. You should probably also watch David Black's opening keynote, which managed to make my hour of precocious grandstanding look measured, meek, and helpful. He actually makes some interesting points, but you'd basically have to ship Richard Dawkins off to Utah, if you wanted to go further out of your way to aggravate your audience. It does give an engaging account of running a large tech comms project, and raise some questions about how we propose to understand a world where increasing amounts of our stuff gets done by increasingly many increasingly complicated tissues of APIs. Well, sort of. That's what all the notes I made were about, anyway.   *Slideshare ate my fonts. Just so we're clear on this: I'd never use badly-kerned Arial in a presentation. Don't worry.

  • PASS Summit 2011 &ndash; Part II

    - by Tara Kizer
    I arrived in Seattle last Monday afternoon to attend PASS Summit 2011.  I had really wanted to attend Gail Shaw’s (blog|twitter) and Grant Fritchey’s (blog|twitter) pre-conference seminar “All About Execution Plans” on Monday, but that would have meant flying out on Sunday which I couldn’t do.  On Tuesday, I attended Allan Hirt’s (blog|twitter) pre-conference seminar entitled “A Deep Dive into AlwaysOn: Failover Clustering and Availability Groups”.  Allan is a great speaker, and his seminar was packed with demos and information about AlwaysOn in SQL Server 2012.  Unfortunately, I have lost my notes from this seminar and the presentation materials are only available on the pre-con DVD.  Hmpf! On Wednesday, I attended Gail Shaw’s “Bad Plan! Sit!”, Andrew Kelly’s (blog|twitter) “SQL 2008 Query Statistics”, Dan Jones’ (blog|twitter) “Improving your PowerShell Productivity”, and Brent Ozar’s (blog|twitter) “BLITZ! The SQL – More One Hour SQL Server Takeovers”.  In Gail’s session, she went over how to fix bad plans and bad query patterns.  Update your stale statistics! How to fix bad plans Use local variables – optimizer can’t sniff it, so it’ll optimize for “average” value Use RECOMPILE (at the query or stored procedure level) – CPU hit OPTIMIZE FOR hint – most common value you’ll pass How to fix bad query patterns Don’t use them – ha! Catch-all queries Use dynamic SQL OPTION (RECOMPILE) Multiple execution paths Split into multiple stored procedures OPTION (RECOMPILE) Modifying parameter values Use local variables Split into outer and inner procedure OPTION (RECOMPILE) She also went into “last resort” and “very last resort” options, but those are risky unless you know what you are doing.  For the average Joe, she wouldn’t recommend these.  Examples are query hints and plan guides. While I enjoyed Andrew’s session, I didn’t take any notes as it was familiar material.  Andrew is a great speaker though, and I’d highly recommend attending his sessions in the future. Next up was Dan’s PowerShell session.  I need to look into profiles, manifests, function modules, and function import scripts more as I just didn’t quite grasp these concepts.  I am attending a PowerShell training class at the end of November, so maybe that’ll help clear it up.  I really enjoyed the Excel integration demo.  It was very cool watching PowerShell build the spreadsheet in real-time.  I must look into this more!  On a side note, I am jealous of Dan’s hair.  Fabulous hair! Brent’s session showed us how to quickly gather information about a server that you will be taking over database administration duties for.  He wrote a script to do a fast health check and then later wrapped it into a stored procedure, sp_Blitz.  I can’t wait to use this at my work even on systems where I’ve been the primary DBA for years, maybe there’s something I’ve overlooked.  We are using EPM to help standardize our environment and uncover problems, but sp_Blitz will definitely still help us out.  He even provides a cloud-based update feature, sp_BlitzUpdate, for sp_Blitz so you don’t have to constantly update it when he makes a change.  I think I’ll utilize his update code for some other challenges that we face at my work.

  • GLSL, is it possible to offsetting vertices based on height map colour?

    I am attempting to generate some terrain based upon a heightmap. I have generated a 32 x 32 grid and a corresponding height map - In my vertex shader I am trying to offset the position of the Y axis based upon the colour of the heightmap, white vertices being higher than black ones. //Vertex Shader Code #version 330 uniform mat4 modelMatrix; uniform mat4 viewMatrix; uniform mat4 projectionMatrix; uniform sampler2D heightmap; layout (location=0) in vec4 vertexPos; layout (location=1) in vec4 vertexColour; layout (location=3) in vec2 vertexTextureCoord; layout (location=4) in float offset; out vec4 fragCol; out vec4 fragPos; out vec2 fragTex; void main() { // Retreive the current pixel's colour vec4 hmColour = texture(heightmap,vertexTextureCoord); // Offset the y position by the value of current texel's colour value ? vec4 offset = vec4(vertexPos.x , vertexPos.y + hmColour.r, vertexPos.z , 1.0); // Final Position gl_Position = projectionMatrix * viewMatrix * modelMatrix * offset; // Data sent to Fragment Shader. fragCol = vertexColour; fragPos = vertexPos; fragTex = vertexTextureCoord; } However the code I have produced only creates a grid with none of the y vertices higher than any others.
