  • How can I test if my rotated rectangle intersects a corner?

    - by Raven Dreamer
    I have a square, tile-based collision map. To check if one of my (square) entities is colliding, I get the vertices of the 4 corners, and test those 4 points against my collision map. If none of those points are intersecting, I know I'm good to move to the new position. I'd like to allow entities to rotate. I can still calculate the 4 corners of the square, but once you factor in rotation, those 4 corners alone don't seem to be enough information to determine if the entity is trying to move to a valid state. For example: In the picture below, black is unwalkable terrain, and red is the player's hitbox. The left scenario is allowed because the 4 corners of the red square are not in the black terrain. The right scenario would also be (incorrectly) allowed, because the player, cleverly turned at a 45* angle, has its corners in valid spaces, even if it is (quite literally) cutting the corner. How can I detect scenarios similar to the situation on the right?

  • Which programming language to develop software for USC that also runs on other OS?? (WINDOWS/OSX)

    - by Marian Lux
    I have skills in JAVA and C#: First i had a closer look to JAVA (Eclipse with Windowbuilder-Plugin) - Swing: But there is no natvie GUI-Support for GTK3 (e.g., HUD seems not to work) Then i was at JAVA - SWT: It is to heavy. I want do code a small app that improves the Ubuntu desktop. I don't want to ship a program with eclipse included. After that i found C# Mono (Monodevelop): GTK-shparp is only for GTK2 available. A GTK3-port will come soon but is it possible to convert the program from GTK2 to GTK3 without extra adaptations? The next bad thing is, that MONO is now dropped from Ubuntu LTS 12.04. So i have no chance that my app would be a default-app in an Ubuntu-Image. (This is also a factor for me to choose a programming language). I know there are other techs but i want to use as programing language JAVA or C#.

  • Mi-Fi LEGO Contest Showcases Ultra Minimal Sci-Fi Designs

    - by Jason Fitzpatrick
    Many LEGO creations showcased by geeks across the web involve thousands upon thousands of bricks to create perfectly scaled recreations of buildings, movie scenes, and more. In this case, the goal is to recreate an iconic Sci-Fi scene with as few bricks as possible. Courtesy of the LEGO enthusiast site The Living Brick, the Microscale Sci-Fi LEGO Contest or Mi-Fi for short, combines Sci-Fi with tiny, tiny, recreations of scenes from shows and movies in the genre. Hit up the group’s Flickr pool for the contest to check out all the great submissions–including a tiny Star Gate, a mini Star Destroyer, and a surprisingly detailed scene from Planet of the Apes.

  • What are basic programming directions? [closed]

    - by Goward Gerald
    What are basic programming directions? Can you please list them and give a brief review of each? Would be nice to have a list for each direction (web-development/*enterprise*/standalone/*mobile*/etc, correct me if I skipped something) like this: 1). Most popular languages of this direction (php for web, objective C for iOS mobile development etc) 2). It's demand on market (from 0 to 5, subjective) 3). How much tasks differ (do you always create same-of-a-kind programs which are like clones of each oother or projects change and you often get to create something interesting, new and fresh?) 4). Freelance demand (from 0 to 5) 5). Fun factor (from 0 to 5, totally subjective but still write it please) Thanks!

  • How to Banish Duplicate Photos with VisiPic

    - by Jason Fitzpatrick
    You meant well, you intended to be a good file custodian, but somewhere along the way things got out of hand and you’ve got duplicate photos galore. Don’t be afraid to delete them and lose important photos, read on as we show you how to clean safely. Deleting duplicate files, especially important ones like personal photos, makes a lot of people quite anxious (and rightfully so). Nobody wants to be the one to realize that they deleted all the photos of their child’s first birthday party during a hard drive purge gone wrong. In this tutorial we’re going to show you how to go beyond the limited reach of  tools which simply compare file names and file sizes. Instead we’ll be using a program that combines that kind of comparison with actual image analysis to help you weed out not just perfect 1:1 file duplicates but also those piles of resized for email images, cropped images, and other modified images that might be cluttering up your hard drive.

  • How to deal with project managers who micromanage?

    - by entens
    Perhaps I'm just naive, but when I try to decipher the wall of tasks I'm targeted to do over the course of a week, I just can't help but think whoever builds the project schedule needs to get some remedial training on basic project management. For example, I am assigned 13 tasks today, the shortest lasting .13 days (default time metric in Microsoft Project), and the longest lasting .75 days. I can't help but think that it is blatant micromanagement scheduling projects in sub 10 minute intervals. The effects of management are becoming evident in slipped tasks, resource assignment exceeding capacity by a factor of two at some points in time, and spending more time clearing tasks and figuring out what comes next than actually doing work. How can I convince the project manager to create tasks with larger duration and to see the larger picture?

    Just because you’re stuck at your desk doesn’t mean you can’t sneak in a little fun. At BuildWithChrome you can slap together virtual LEGO bricks with ease. The site, a collaboration between Google and LEGO, shows you a massive map of Australia and New Zealand covered in thousands of LEGO base plates. Zoom in, select a base plate, and get building. The block selection is fairly limited (you can work with the kind of blocks you’d find in a generic LEGO brick pack) but it’s still quite a bit of fun.

  • Microsoft BUILD 2013 Day 1&ndash;Keynote

    - by Tim Murphy
    Originally posted on: http://geekswithblogs.net/tmurphy/archive/2013/06/27/microsoft-build-2013-day-1ndashkeynote.aspx This one is going to be a little long because the keynote was jam-packed so bare with me. The keynote for the first day of BUILD 2013 was kicked off by Steve Balmer.  He made it very clear that Microsoft’s focus is on accelerating its time to market with products and product updates.  His quote was that “Rapid release” is the new norm.  He continued by showing off several new Lumias that have been buzzing around the internet for a while and announce that Sprint will now be carrying the HTC 8XT and Samsung ATIV. Balmer is known for repeating words or phrase for affect.  This time it was “Rapid release, rapid release” and “Touch, touch, touch, touch, touch, …”.  This was fun, but even more fun was when he announce that all attendees would receive an Acer Iconia 8” tablet. SCORE! The next subject Balmer focused on is new apps.  The three new ones were Flipboard, Facebook and NFL Fantasy Football.  I liked the first two because these are ones that people coming from other platforms are missing.  The NFL app is great just because it targets a demographic that can be fanatical.  If these types of apps keep coming than the missing app argument goes away. While many Negative Nancy’s are describing Windows 8.1 as Windows 180 Steve Balmer chose to call it a “refined blend” as in a coffee that has been improved with a new mix.  This includes more multi-tasking options and leveraging Bing straight throughout the entire ecosystem. He ended this first section by explaining that this will also bring more Bing development opportunities to the community. Steve Balmer was followed by Julie Larson-Green who spent her time on stage selling us on Windows 8 all over again from my point of view.  Something that I would not have thought was needed until I had listened to some other attendees who had a number of concerns and complaints.  She showed a number of new gestures that will come with Windows 8.1, and while they were cool I was left wondering if they really improved the experience.  I guess only time will tell. I did like the fact that it the UI implementation to bring up “All Apps” now mirrors that of Windows Phone.  The consistency is a big step forward that I hope to see continue.  The cool factor went up from there as she swiped content from a desktop (mega-tablet) to the XBox One.  This seamless experience I believe is what is really needed for any future platform to be relevant. I was much more enthused by the presentation of Antoine Leblond who humbled us by letting us know that there are 5k new API.  How that can be or how anyone would ever use all of them is another question.  His announcement was that the Visual Studio 2013 preview would be available today along with the Windows 8.1 bits.  One of the features of VS2013 that he demonstrated is the power consumption profiler.  With battery life being a key factor with consumer consumption devices this is a welcome addition. He didn’t limit his presentation to VS2013 features though.  He showed how the Store has been redesigned to enable better search and discoverability of apps and how Win 8.1 can perform multiple screen scales depending on the resolution of the device automatically.  The last feature he demoed was the real time video streaming API which he made sure we understood by attaching a Surface to a little robot.  Oh, but there was one more thing.  Antoine and Julie announce that all attendees would also be getting Surface Pros.  BONUS! How much more could there be?  Gurdeep Singh Pall was about to pile on.  He introduced us to Bing as a platform (BaaP?).  He said if they (Microsoft) could do something with and API that is good 3rd party developers can do something that is dynamite and showed us some of the tools they had produced.  These included natural user interface improvements such as voice commands that looked to put Siri to shame.  Add to that 3D, OCR and translation capabilities and the future looks to be full of opportunities. Balmer then came out to show us one last thing.  Project Spark is a game design environment that will be available for Windows 8.1, XBox 360 and XBox One.  All I can say is that if my kids get their hands on this they are going to be able to learn some of what dad does in a much more enjoyable way. At the end of it all I was both exhausted and energized by what I saw.  What could they have possibly left for the day 2 keynote?  I hear it will feature Scott Hanselman.  If that is right we are in for a treat.  See you there. del.icio.us Tags: BUILD 2013,Windows 8.1,Winodws Phone,XAML,Keynote,Bing,Visual Studio 2013,Project Spark

If these components are not effectively shared by project leads and understood by stakeholders, project outcomes can be jeopardized and budgets may incur unnecessary risk. As reported by PMI’s 2013 Pulse of the Profession, an organization’s ability to meet project timelines, budgets and especially goals significantly impacts its ability to survive—and even thrive. The Pulse study revealed that the most crucial success factor in project management is effective communication to all stakeholders—a critical core competency for public agencies. PMI’s 2013 Pulse of the Profession report revealed that US$135 million is at risk for every US$1 billion spent on a project. Further research on the importance of effective project team communication uncovers that a startling 56 percent (US$75 million of that US$135 million) is at risk due to ineffective communication. Simply stated: public agencies cannot execute strategic initiatives unless they can effectively communicate their strategic alignment and business benefits. Executives and project managers around the world agree that poor communication between project team members contributes to project failure. A Forbes Insights 2010 Strategic Initiatives Study “Adapting Corporate Strategy to the Changing Economy,” found that nine out of ten CEOs believe that communication is critical to the success of their strategic initiatives, and nearly half of respondents cite communication as an integral and active component of their strategic planning and execution process. Project managers see it similarly from their side as well. According to PMI’s Pulse research, 55 percent of project managers agree that effective communication to all stakeholders is the most critical success factor in project management. As we all know, not all projects succeed. On average, two in five projects do not meet their original goals and business intent, and one-half of those unsuccessful projects are related to ineffective communication. Results reveal that while all aspects of project communication can be challenging to public agencies, the biggest problem areas are: A gap in understanding the business benefits. Challenges surrounding the language used to deliver project-related information, which is often unclear and peppered with project management jargon. Public agencies -- federal, state, and local -- have difficulty communicating with the appropriate levels with clarity and detail. This difficulty is likely exacerbated by the divide between each key audience and its understanding of project-specific, technical language. For those involved in public sector project and portfolio management, I would be interested to hear your thoughts and please visit Primavera EPPM solutions for public sector.

  • Is it common to purchase an insurance policy for contract development work?

    - by Matthew Patrick Cashatt
    I am not sure if this is the best place for the question, but I am not sure where else to ask. Background I am a contract developer and have just been asked to provide a general liability policy for my next gig. In 6-7 years this has never been asked of me. Question Is this common? If so, can anyone recommend a good underwriter that focuses on what we do as contract software developers? I realize that Google could help me find underwriters but it won't give me unbiased public opinion about which companies actually understand what we do and factor that into the price of the policy. Thanks, Matt

  • Does not documenting code result in job security? [closed]

    - by Barry Brown
    Possible Duplicate: Should you write good documentation and clean code to increase the “Bus Factor”? I often ask young programmers why they are not documenting their code. Their responses, perhaps jokingly, frequently include "job security." I hear this from experienced professionals, too. And not just in programming; network engineers and system administrators widely subscribe to this belief. Can you really ensure job security by holding the details of your work in your head rather than on paper (or in files)? What's your experience?

  • Does text size and placement on page have an effect on seo

    I was wandering seeing as Google and others keep trying to get more and more 'human' in terms of rating whats good and whats spam, is it known if they take into account the size of a heading ie. an thats font size is 40px is going to speak allot more to the user than a thats font size is 14px.. similarly does placement factor ? ie. a 300 word article at the bottom of a landing page (not in the footer but bellow the useful content) would just be there for seo purposes. i know they look at if your doing things like text-indent:-9999px; and white text on a white background, but what about these more border line practices that both have legitimate uses but also the possibility to be spammy

  • Automatically zoom out the camera to show all players

    - by user36159
    I am building a game in XNA that takes place in a rectangular arena. The game is multiplayer and each player may go where they like within the arena. The camera is a perspective camera that looks directly downwards. The camera should be automatically repositioned based on the game state. Currently, the xy position is a weighted sum of the xy positions of important entities. I would like the camera's z position to be calculated from the xy coordinates so that it zooms out to the point where all important entities are visible. My current approach is to: hw = the greatest x distance from the camera to an important entity hh = the greatest y distance from the camera to an important entity Calculate z = max(hw / tan(FoVx), hh / tan(FoVy)) My code seems to almost work as it should, but the resulting z values are always too low by a factor of about 4. Any ideas?
