  • How to make an object fly out of a slingshot?

    - by Deza
    At the moment I'm improvising a slingshot, the user can click and drag the projectile and let go. The force on the object is calculated by getting the distance between the vector of the slingshots two forks and the vector between where the user pulled it. However this will always result in a positive number and will not take into account the angle of the object relative to that of the slingshot. How can I make it fly out of the slingshot correctly?

  • Is possible to create an intranet site in Ruby on Rails? [closed]

    - by Akromyk
    I'm just coming out of a .Net course and I'm wondering whether it is possible to create an intranet site using Ruby on Rails, and if so, would it even be a good idea. I plan on creating a web site for a vendor that hopes to open up a physical location and it would be beneficial for us to go with a technology that could tie their web front into their intranet for helping them manage orders and logins, but at the same time still have a low cost.

  • Why do programs take more than 2 seconds to load on my Ubuntu 12.04?

    - by Gaige
    Here's a description of my build (simple) Processor: AMD Phenom II x6 1090t Ram: 16gb 1333 mhz Board: TA990FXE Video Card : HD 6870 HDD Ubuntu is installed on: 320gb caviar blue 7200rpm That should be sufficient enough to diagnose this. Yes I did install the AMD video drivers recommended by Ubuntu. Programs take 2+ seconds to load, and I really don't tolerate that...Windows 7 loads programs as fast as my hdd allows Unless this is how Ubuntu is meant to work...then I'll just go back to Debian command-line.

When i go to Software center and search for compizconfig, it says that it is already installed.But when i search it from the list of installed applications, i couldn't find it.??

  • Microsoft Patches Internet Explorer 9, Launches YourBrowserMatter

    Due to the critical status of the Internet Explorer 9 fix, any users with the recommended Windows Update setting of install updates automatically enabled should receive it by default. Microsoft urges users with automatic updates disabled to install the fix manually via Windows Update. IT administrators in charge of handling organizations are urged to do the same using their go-to software for managing patches in-house. Of the eight vulnerabilities targeted by the IE9 update, the most crucial make it possible for remote code execution to occur on PCs where users have visited certain affecte...

  • Policies for deciding which mobile devices/OS versions to support? [on hold]

    - by bobfet1
    When developing for mobile devices, what are some strategies to go about determining which mobile devices and OS versions to support? Do some teams set a certain policy in place, like "support devices used by more than 2% of users" or "support OS versions with over 10% of users?" For example, a reoccurring challenge I am running into is the decision whether to support only new OS versions like iOS7 or KitKat, or continue support for older versions. It would be helpful to know how others approach this decision.

  • What version(s) of Android should I be targeting?

    - by Bill Osuch
    If you're wondering about what screen sizes and flavors of Android are currently out in the wild, the Android Developers site has a handy little chart of both (each image below is hyperlinked to the page): So, as far as platforms go, there aren't many people still out there running less than 2.X... and you'd probably be safe not worrying about Small or Low Density screens. I'd be curious to know if any of the other app stores (Amazon, Archos, etc.) offer similar stats...

  • A quick look at: sys.dm_os_buffer_descriptors

    - by fatherjack
    SQL Server places data into cache as it reads it from disk so as to speed up future queries. This dmv lets you see how much data is cached at any given time and knowing how this changes over time can help you ensure your servers run smoothly and are adequately resourced to run your systems. This dmv gives the number of cached pages in the buffer pool along with the database id that they relate to: USE [tempdb] GO SELECT COUNT(*) AS cached_pages_count , CASE database_id ...(read more)

  • Introduction to Agile Development

    - by Grant Fritchey
    Even though my current job is a little weird, I still consider myself to be a DBA. I didn’t start that way in IT. I came through support and into development. I loved development. There was a constant struggle to attempt to improve your code, your understanding, and, most importantly, the process of development itself. Development can be slow and tedious. Left alone, developers can simply disappear to build a project and not come back for two years, at which time they deliver it. But, maybe that software isn’t what you wanted, or it’s no longer needed, or who knows what. So developers are constantly attempting to improve their processes in order to deliver more relavent software quicker (something DBAs could learn about). I really admire it. One of the many processes that has come out of that constant striving is known as Agile. As the name implies, Agile development attempts to come up with a quick, fast turning, business aware, well, for want of a word, agile, process that is more responsive to the needs of the business. There are tons and tons of books and blogs and videos on the subject that can get you going. But, Agile isn’t easy (note, Easy is not part of the name). Agile processes can be hard. I’ve worked on multiple agile teams, some successful, some not. The two principal differences between the teams were their discipline and their knowledge of the process. Discipline, that comes from within. But knowledge, ah, well there I can help. Red Gate is bringing a series of free instructional events to the United States in a few weeks time focused primarily on SQL Server (click here right now to register while there’s still space). We’re also offering some .NET instruction too. That’s a full day, free, with top experts in the business. But, the next day, there’s a full day session introducing Agile. You can go to this and learn how to do Agile. Develop that knowledge that will enable you to successfully use the Agile process. Go to this web site to check it out. No, this event is not free, but not everything can be. And it’s not just for developers. DBAs, you need to learn this stuff too. Management could also benefit from understanding these processes (because you guys can help to enforce discipline). It’s really for everyone involved in the development process.

  • Considering SEO?

    Many businessmen go online without realizing they need to work beyond the construction and launching phases of their websites to make them effective. They can have the best designs and the best content, but if people don't even know such sites exist, then they become practically useless. A business benefits from a website because of the marketing edge it makes possible, but how can a website even market itself when very few people are checking it out? This is the reason why search engine optimization service professionals exist.

    Possible Duplicate: Disable joining multiple windows to one icon in unity panel If I have two vlc players open, I have to go to the sidebar and click on the vlc icon, then pick which one I want (it does this cool effect where it shows you both windows side by side-- as great as that is, it gets bloody annoying after a while). Is there not an easier way of doing this? Is there no possibility of reverting back to the old system?

  • AMD Drivers problem

    - by Darthkpo
    So, I'm kind of new to Ubuntu and Linux in general, I installed the latest (Ubuntu 14.04) and everything went fine, except for the resolution so I thought that it was a driver problem because I have a AMD HD 7750 and maybe it required additional proprietary drivers so I installed AMD Catalyst (Latest version), and then rebooted. And now my monitor says Can't Display and I can't see the GUI. I can go to terminal (Pressing Ctrl + Alt + F1, F2, F3 etc) but Not the UI.

  • What would you do if there was no Internet? [closed]

    - by Jinjavajin
    If the International Network no longer functioned how would programmers cope? Would software development become an intractable problem? So much development has been achieved because of our interconnectivity that we might not be able to go forward as a community, without it. Is this the case, or might we become more productive due to the removal of a major distraction? How would we cope if the the network went down?
