  • Almost time to hit the road again

    - by Chris Williams
    I’ve had a few months of not much traveling, but now that the weather is improving… conference season is starting up again. That means it’s time for me to start hitting the road. In June, I have Tech Ed 2010 in New Orleans, LA. I lived in New Orleans for several years, both as military and civilian and I have a few friends still down there. I haven’t been there since before Hurricane Katrina, so I have mixed feelings about returning… but I am still looking forward to it. Also in June, I have Codestock in Knoxville, TN. Codestock is one of my favorite events, primarily because of the excellent people that speak there and also attend sessions. It’s a great mix of people and technologies. Sometime in July or August, I’m headed to Austin, TX for a couple days. I don’t know the exact date yet, but if you have an event down there in that timeframe, let me know and maybe we can sort something out. In September, I’m heading to Seattle for my first PAX (Penny Arcade Expo.)  I’m going strictly as an attendee and it looks like a LOT of fun. Really excited to check it out. Also in September, I’m headed to Omaha for the Heartland Developers Conference. This is a FANTASTIC event, and certainly one of my local favorites. (I guess local is relative, it’s about a 6 hour drive.) In addition to speaking on WP7, I’ll be doing a series of hands on labs on XNA they day before the conference starts, so that should be a lot of fun as well.   In addition to all this stuff, I have my own XNA User Group to take care of. In August, Andy “The Z-Man” Dunn is coming to speak and check out the various food on a stick offerings at the Minnesota State Fair!

  • How to make xlock use the first key I hit as a part of my password

    - by alesplin
    I just switched from Arch Linux to Ubuntu 10.10. I'm running the Fluxbox window manager, and I use xlockmore to lock my screen with the following key shortcut: 192 :Exec xlock-mode marquee +usefirst -icongeometry 240x240 -message "back in a minute..." The problem I'm having is that xlock is definitely not using my first key as part of my password. Instead, it uses some randomized fade pattern to fade to the password screen. I find this highly annoying, as when I get back to my desk and start entering my password it doesn't register password characters until the fade pattern is complete. I've also tried the following modifications with no difference: 192 :Exec xlock -mode marquee -usefirst -icongeometry 240x240 -message "back in a minute..." 192 :Exec xlock -mode marquee -icongeometry 240x240 -message "back in a minute..." The first example worked flawlessly on Arch. Does Ubuntu have some sort of system default that you can't override on the command-line?

  • AABB - AABB Collision, which face do I hit?

    - by PeeS
    To allow my objects to slide when they collide, I need to : Know which face of the AABB they collide with. Calculate the normal to that face. Return the normal and calculate the impulse that to apply to the player's velocity. Question How can I calculate which face of the AABB I collided with, knowing that I have two AABB's colliding? One is the player and the other is a world object. Here's what that looks like (problem collision circled in white): Thank you for your help.

  • Calculating Hit Accuracy score in a game

    - by N0xus
    I'm currently in the process of making a scoreboard for my game. One of things I would like to display is the players accuracy in the amount of hits they had in game. However, I have never done this before and I've no idea how to go about doing this. Is there a commonly used algorithm out there that can help me calculate this, or has someone found a way to calculate this fairly easily? Any help with this would be appreciated.

  • KWin Can Cause A Performance Hit Too, But It's Different From Compiz

    <b>Phoronix:</b> "This surprised many so we published another article entitled The Cost Of Running Compiz where we showed the performance penalties of a compositing window manager with different hardware and drivers. This led some to ask whether the performance of KWin also causes the OpenGL frame-rate to drop, so here are those KDE benchmarks."

  • Ubuntu 12.10 installation. Hit or miss Booting

    - by Robert
    I just recently downloaded and installed Ubuntu 12.10. I also completely wiped the laptop. The Ubuntu OS will only boot part of the time but never on the first time. Always, the first start up will automatically go to a purple screen and stay there. At first I waited for 45 minutes and nothing changed. Once I held down the power button to turn it off, I turned it back on to see the Asus screen followed by the grub menu. I can select "Ubuntu" and then there is a white box blinking in the top left corner. Then, it will either keep blinking or transfer to the Ubuntu loading screen(everything works fine if it gets to the loading screen). This has never happened before with prior versions of Ubuntu. Any ideas are helpful. Thanks!

  • USB keyboard hit and miss as to whether it will work on boot-up

    - by user208745
    I am new to Ubuntu. Have installed 12.04 on a slave drive while I migrate. Usually booting into Ubuntu goes without a hitch but recently I often find I am unable to use the keyboard, and log-in using the on-screen KB. Sometimes if I remove the USB jack & re-connect it will start working again but not always. I do have an old PS/2 KB which I am using at the moment but.......has anyone any ideas on how to get the USB KB reliably connected? Thanks Dave

  • Highlighting repeating groups in SSRS 2008 R2 charts

    In a typical bar chart, the height of the bars represents the value of the data along the X axis and the Y axis represents the category of the data point. All these values can be classified in logical groups depending upon the logic used for analysis. One general requirement that arises in the case of repeating groups, is to highlight these groups without representing it on the X or Y scale. In this tip we will look at how to address this requirement.

  • Syntax Recognition for XML-Based Languages in Oracle JDeveloper

    - by Ramkumar Menon
      @Thanks Jeffrey Stephenson If you are looking at using any one of the new XML Based languages, lets say a docbook xml, or xproc, or what not, you can make use of JDeveloper's syntax highlighting and completion insight feature to ease out those extra keystrokes. All you need is a URL/local copy of the XML Schema for the language. Once you have, you can register it via Tools --> Preferences --> XML Schemas.   Remember to provide a new extension name [Using a default .xml extension did not work for me.] I provided my own extension .dbk for my docbook files. Once you save these settings, you can create new files that conform to the schema, and you get validation/completion insight/prompting for free.

  • TextMate suddenly highlighting all text dark red...?

    - by AP257
    I'm using TextMate on Snow Leopard, don't know much about how it works. After I hit an unknown keyboard shortcut, it suddenly decided to highlight almost all text in my Python files dark red - making all my Python virtually unreadable! I must have accidentally pressed a shortcut - but I've no idea what I did or how to turn it off, and can't find any relevant help in the manual or form. Even just 'turn off all highlighting' would do. Anyone know how to turn this highlighting off? Bit desperate! UPDATE: Figured it out. There's a tiny, tiny dropdown list at the very bottom of every TextMate editing window where you can set the language, so TextMate can highlight invalid syntax - I'd accidentally clicked on it and set the language to something other than Python. Will leave the question up though in case others have the same problem.

  • Fix YAML syntax highlighting in VIM

    - by Kevin Burke
    The YAML syntax highlighting in Vim 7.3 isn't great. Putting an apostrophe in a line of text triggers quote highlighting even when there's no quote. The same thing happens in other files sometimes too. I've posted a screenshot below. Is there any way to fix this behavior, or is there a different YAML syntax file I can use that won't trigger this behavior? This occurs in both MacVim and Vim in the Terminal. I'm running v7.3. Thanks for your help, Kevin

    Guys, feature in new release of Visual Studio which is block/region highlighting, I think is quite useless, and definitely frustrating when every time my cursor passes this line my whole region is being highlighted. Does anyone of you feel the same way and if not do you find this usefull for anything? Because I can't.
