  • Is porting a Windows application to Mac worth it ?

    - by mikel
    I have a C# Windows application that sells for $35, and fairly regularly receive requests for a version for OS X too. I don't have any experience with Mac so far though, and so am not sure exactly how much work that would involve and if it would be worth it. If anyone's been in a similar position, it'd be very helpful to know: Roughly how many more (%) sales can you expect by porting to Mac ? Would you say it's worth the investment of a new Macbook Pro and the time of learning and porting to Objective-C ? Thanks in advance.

  • Why is my fan constatnly blowing in Ubuntu?

    - by Derfder
    I have installed Ubuntu 13.04 (64-bits) alongside Windows 7 on different partition on my second desktop. It's working nice. I have updated everything. However, I have problems with my fan.

  • How to disable three finger gestures on touchpad?

    - by oznah
    I am using 12.04 on a macbook pro. Everything works really well. I want to disable 3 finger gestures. It is way to easy to accidentally drag/move a window(3 finger gesture) while scrolling(2 finger gesture) when using a touchpad. I found this answer on ask ubuntu. It was marked answered but it is not. The functionality is still there. All this recommendation does is disable the drag marks on the window. This may be tricky because I want to disable 3 finger gestures but not 2 finger gestures. (ie I don't want to disable touchpad gestures all together)

    - by Fabrice Marguerie
    Microsoft has just published a new free extension for Visual Studio 2010 that provides an improved Add Reference dialog, an improved tab bar, and much more.The new Add Reference dialog comes with a long-awaited feature: it's now searchable!The tab bar allows you to display the close button at the end of the bar and not on each tab. It can also sort tabs by project and alphabetically. Tab color can vary by project or according to regular expressions.I'll let you discover about the other features by yourself (HTML Copy, Triple Click, Current Line Highlighting, etc.).The name of the extension is Visual Studio Pro Power Tools. I believe it's main features will come out-of-the-box with the next version of Visual Studio.

  • Wi-fi interface fails to authenticate on secured networks

    - by Eduardo Bezerra
    the problem is that I can't connect to wireless networks that have security enabled. I can connect fine to the unsecured network of my university, but not to the secured one in the same building. Also, it fails to connect to my home wireless router, which uses wpa2 encryption. Any ideas? I have a Broadcom Corporation BCM43224 802.11a/b/g/n (rev 01), with pci id [14e4:4353], running Ubuntu 12.10 on a macbook pro 6,2. I'm using bcmwl-kernel-source package with kernel module wl to enable my wi-fi device.

  • What a week! Oracle OpenWorld & Maria Bartiromo (CNBC)

    - by Carlos Chang
    It's been a week since the end of Oracle OpenWorld and JavaOne and both events were a huge success! We had many announcements including Oracle ADF Mobile, Oracle ADF Essentials, Oracle Developer Cloud Service and tons more.  Above is a picture I snapped of Maria Bartiromo from CNBC, who was there to interview Larry Ellison and Mark Hurd.  The stage was right in the midst of the booths that showcased new products, at Moscone North.  She's such a pro. With all the noise and people milling around gawking and taking pictures (myself included) she was solid & composed.   Her level of focus and the production quality of the show is impressive. She later stopped by for a demo of OEPE's  new support for Oracle ADF as well as Oracle Developer Cloud Service. She seemed impressed too. ;-)

  • Why does my touchpad fail on resume from standby?

    - by pst007x
    On resume touchpad disables and a reboot is needed to re-activate. Macbook Pro 6.1 Ubuntu 11.10 MAC 64bit Suspend - ok Suspend Resume - ok However, on resume in the loggin screen my touchpad works, but after I enter my password and return to the desktop the touchpad fails. A usb mouse still works fine. I have to re-boot in order to re-enable toe touchpad. This was not an issue when I had Ubuntu 10.10 32bit installed. The install was a fresh install. The bcm5974 driver will not install, says codependency errors. I manually try to install all dependencies and I get this error: E: hid-dkms: subprocess installed post-installation script returned error exit status 10 E: bcm5974-dkms: dependency problems - leaving unconfigured Thanks

  • Expressing the UI for Enterprise Applications with JavaFX 2.0 FXML - Part Two

    - by Janice J. Heiss
    A new article by Oracle’s Java Champion Jim Weaver, titled “Expressing the UI for Enterprise Applications with JavaFX 2.0 FXML -- Part Two,” now up on otn/java, shows developers how to leverage the power of the FX Markup Language to define the UI for enterprise applications. Weaver, the author of Pro JavaFX Platform, extends the SearchDemoFXML example used in Part One to include more concepts and techniques for creating an enterprise application using FXML. Weaver concludes the article by summarizing its content, “FXML provides the ability to radically change the UI without modifying the controller. This task can be accomplished by loading different FXML documents, leveraging JavaFX cascading style sheets, and creating localized resource bundles. Named parameters can be used with these features to provide relevant information to an application at startup.” Check out the article here.

  • Good 3D Game Engine for the Horror Genre [on hold]

    - by James Wassall
    I am starting to think about and design (pencil drawings) a simple, horror game. I'm in need of a good engine which supports features like Dynamic Lighting (for a characters flashlight) and dynamic shadows. My first choice was obviously Unity3D, as its free and is (supposedly) the easiest to use. However, I believe that a lot of features are locked for the Pro version (a $1500 investment). Is there any good, free engines that support dynamic events? I have read a lot of posts recommending the Source engine but I don't want to make a mod, I would like to make a fully featured standalone game. I'm not looking for opinions on "Which engine you prefer" or "Which engine do you use", all I would like is to be presented with the facts. -James

  • Why does starting a program log me out?

    - by Bruce McKean
    I'm not a computer nerd but have been able to fix Ubuntu/Linux problems in the pass two years with a Google search but this on has me stumped. I upgraded to 12.04 about thirty days ago and all was well except that every time I tried to load KeePassX it would go to the login screen. I installed KeePass2 and all seemed to work. Last week I tried to load Bibble5 (Raw photo editor) and it would try to load and then back to the login screen. After a few days I gave up and downloaded Corel After Shot Pro (Corel's now owns Bibble5) and it has the same problem. Could someone please head me into the steps I need to follow to find out what is the cause? I'm interested in learning more about the Linux system. How to correct any future problems like this?

  • When creating a new text file, should I add a .txt extension to its name?

    - by Agmenor
    When I create a new document aimed at containing only plain text, I am not obliged by Ubuntu to add a .txt extension to its name. It works indeed very well: gedit opens it without problem, understanding very well that it is only text. The only two pro arguments I have found from now on for adding an extension are 1/ interoperability with Windows systems and 2/ avoiding confusion with folders having the same name. Nevertheless those two arguments do not convince me at all. As a consequence, should I keep the reflex of adding an extension to files or not?

  • From Pocket to Instapaper

    - by Michael Freidgeim
    Some time ago I’ve described the issues that I’ve had since a new version of Read It Later, named Pocket, was introduced.I’ve waited with hope for a new upgrade, but I had a huge disappointment with the latest version 16 June 2012. It didn’t fixed any of the two major problems, that I  experienced since new Pocket was introduced-  1. iPad app still didn’t show many of the saved links. 2. ability to rename articles on iPad still wasn’t restored.I’ve posted the message into their forum. They did not show my comment on their forum( I would name it censorship, not moderation), but a few days ago I’ve received an email, recommending “try logging out of the app on your iPad, and back in again.” Their suggestion helped,  but I don’t understand, why it is not posted as a recommendation on their support site.So I decided to try InstAPaper on my iPad, Previously I’ve used it for Kindle. I never considered it before on iPad, because there were no free demo and I was very satisfied with RIL free and then RIL Pro. Currently InstAPaper cost $3, so the price is not an issue.I’ve checked that it has most of features that I am using(e.g. renaming, folders) and I am quite happy with it now. Actually I am using Pocket (or RIL free) for old bookmarks( I have 1000+ stored on my iPad) and for new bookmarks I am using InstAPaper.Having a solid experience with RIL/Pocket I’ve created a list of suggestions to Marco Arment to implement.1. Some pages stored in InstAPaper have removed essential sections of the text. E.g in many blogs comments are not stored in  InstAPaper. Some pages lost almost all of important links (e.g. http://www.lib.rus.ec/a/32416 -sorry, in Russian). RIL/Pocket has 2 modes to store offline- Web view and Article view. Web View includes all links/images of the original page, but it’s very reliable. Article view suppose to strip unrelated information, but often corrupts the content. I prefer to use offline Web view.InstAPaper should also support offline Web view, in case if stripped view removes important part of content.2.  Black full screen Saving on iPad Safari is very annoying. After user pressed a bookmark, the saving has some delay and then for a few seconds prevents from reading the text.Would be better to show as message on the top part(as in Pocket ). I am surprised, that  a full screen popup was  implemented recently as a desired feature. 3.There are no comments allowed on http://blog.instapaper.com/. I would prefer to post some of these notes as comments on http://blog.instapaper.com/ rather than write them in my blog and then send link to Marco.(I found recommendation how to add support of comments on tumblr at http://www.tumblr.com/help, but then realized that Marko was the lead developer ofTumblr.)4. Also there is no support forum. I understand that maintenance of the forum ican be a hassle, but stackexchange fSome time ago I’ve described the issues that I’ve had since a new version of Read It Later, named Pocket, was introduced.I’ve waited with hope for a new upgrade, but I had a huge disappointment with the latest version 16 June 2012. It didn’t fixed any of the two major problems, that I  experienced since new Pocket was introduced- orums can be referred on  http://www.instapaper.com/main/support page, i.e.http://webapps.stackexchange.com/search?q=Instapaper  or http://apple.stackexchange.com/search?q=Instapaper 5. Tags are more convenient than folders. i.e. an ability for the same article to have more than one tag. Also creating of new folders is not supported offline, which is an annoying limitation.6. I would like to have a narrow list - additionally to existing list modes have a subject only list or subject+site list to show more list items on a screen.7. Limit of 500 offline articles sounds quite big, but my RIL list exceeded 1000, so it could be a issue in the future.8. Search button on iPad version is visible, but doesn’t work- it forces to buy Premium subscription. I think, that it’s not correct. If the button in a paid version is visible and enabled, it should  provide  a working functionality, e.g. search in article names only. And leave full-text search for the premium support.9..Copy URL is an important operation and deserves to be in a first level of Action menu, rather than in Share sub-menu.I’ve also have comment re post http://www.marco.org/2011/04/28/removed-instapaper-free. Marco Arment  explained, why he doesn’t provide free version of Instapaper.  I believe that he is loosing essential part of his customers. When I decided which of iPad application to choose, I’ve selected RIL, because I was able to play with free version, and I liked it. I didn’t have a chance to compare RIL and InstAPaper on iPad, so I’ve bought  RIL pro. For a user there is no point to pay even $3 , if there are similar free product, that user can try and see, is it suitable for him/her.I’ve also played with Readability. It doesn’t have folders or tags(which is very important for me), but nicely supports full text search

  • Silverlight: Creating great UIs

    - by xamlnotes
    I was always told I was left brained and could not draw. And I bought into that view. Somewhere down the road years ago I did learn to play guitar and to play by ear at that.  Now that’s not all left brained so my right brain must be working.  About a year ago, my good friend Billy Hollis turned me own to a book by Betty Edwards (http://www.drawright.com/).  I started reading this and soon I found my self drawing on napkins in restaurants while we were waiting on food and at many other times too.  Dang’d if I could not draw! Check out my UI article at Dev Pro Connections (Great UIs article) on some of my experiences. Heres a few more links that are really cool too. Cool color combinations web site Simply painting is awesome. Saw this guy on tv. This site has some great tools for color contrasting

    Let's say you're in a computer store looking at 10 laptops, you want to really compare the system's capabilities. What will be an efficient "your fav language goes here" script that will allow you to do this? As an example, when I go to the store I usually open a macbook and a pro's terminal and write an equation in python, iterate it a million or so times, and time them. I like to compare the difference in time. What would be an ideal and simple script that can efficiently compare systems?

You can also run older 3D games in a virtual machine – newer ones probably won’t run very well.

  • Spreadsheet or writing an application?

    - by Lenny222
    When would you keep simple to medium-complex personal calculations in a spread sheet (Excel etc) and when would you write a small program or script for it? For example when you want to calculate what size of mortgage you can afford to buy a house. I could create a spreadsheet and have a nice tabular representation. On the other hand, if i would write a small script in a nice language (in my case Haskell), i'd have the security of a nice type system, preventing typos etc. What are the pro/cons in your opinion?

  • Stuck on Ubuntu startup screen (5 orange bullets)

    - by psyboy14
    I recently download Ubuntu 12.04 LTS onto my Macbook Pro 5-5. Everything worked seamlessly, save for the brightness control. I couldn't change the screen brightness from the hardware buttons, nor from the system preferences. To fix it, I used the instructions here: MacbookPro 5-5 LCD Brightness Control At #2, I restarted my laptop, only to see that it went straight to the Ubuntu Startup Screen, with the 5 orange dots (Usually they all startoff white, then turn orange to indicate progress). From there, I tried controlling the brightness from the keyboard, and it worked, but sadly, my computer is still stuck on the loading screen. (Yes, I have tried manually restarting it) Could you please help? Thank you in advance

  • How do GameEngines stop Pixel Seams appearing in adjacent mesh boundaries due to FP imprecision?

    - by ufomorace
    Graphics cards are mathematically imprecise. So when some meshes are joined by their borders, the graphics card often makes mistakes and decides that some pixels at the seam represent neither object, and unwanted pixels appear. It's a natural behaviour on all graphics cards. How are such worries avoided in Pro Games? Batching? Shaders? Different tangent vectors? Merging? Overlaping seams? Dark backgrounds? Extra vertices at borders? Z precision? Camera distance tweaks? Screencap of a fix that ended up not working:
