  • Please help me to improve Re-Sharper

    - by TATWORTH
    Re-Sharper is an excellent aid to producing good code in either C# or VB.NET. Recently through using Resharper and StyleCop, I have found three area where ReSharper needs to be improved. Please log into the YouTrack at http://youtrack.jetbrains.net and vote for the following: RSRP-268868 Improvement to removal of redundant else and invert if optimisations for enhanced stylecop compliance. When Resharper removes a redundant else, there needs to be a blank line added. Currently there is no provision to specify this. Please vote for this! RSRP-272286 Resharper Feature Request to move initialisation to static constructor Currently ReSharper offers moving initialisation of of non-static variable to a constructor. Why not offer the same for a static constructor?  Please vote for this! RSRP-272285 Expansion of Switch Statement by Resharper Currently ReSharper will fill an empty switch statement based upon an enumeration but will not add missing enumeration values to such a switch statement.   Can't code withoutCoding assistance, smart code editing and code completion for C# and VB.NET

  • IsNullOrEmpty generic method for Array to avoid Re-Sharper warning

    - by Michael Freidgeim
    I’ve used the following extension method in many places. public static bool IsNullOrEmpty(this Object[] myArr) { return (myArr == null || myArr.Length == 0); }Recently I’ve noticed that Resharper shows warning covariant array conversion to object[] may cause an exception for the following codeObjectsOfMyClass.IsNullOrEmpty()I’ve resolved the issue by creating generic extension method public static bool IsNullOrEmpty<T>(this T[] myArr) { return (myArr == null || myArr.Length == 0); }Related linkshttp://connect.microsoft.com/VisualStudio/feedback/details/94089/add-isnullorempty-to-array-class    public static bool IsNullOrEmpty(this System.Collections.IEnumerable source)        {            if (source == null)                return true;            else            {                return !source.GetEnumerator().MoveNext();            }        }http://stackoverflow.com/questions/8560106/isnullorempty-equivalent-for-array-c-sharp

  • Make Ubuntu fonts sharper

    - by Tibo
    In the last two months I'm trying to do a complete transition from Windows 7 to Ubuntu. There is something that is really missing. I really like the sharp and think fonts in windows (I'm not talking about the font type - 'Arial','Consolas' atc.). I think that the Ubuntu fonts looks better, but after several hours I feel like my eyes are really tired. BTW - I have the same problem with the Apple computer at work too (MacBook pro). Is it a theme issue? Can i change it by configuration? Can you recommend a solution?

  • How do I use my own debugger visualiser to edit variables runtime?

    - by C Sharper
    I'm writing my own debugger visualiser. All works great to show up to visualiser with the data. Now I add the code for more clearness: public class MyVisualiserObjectSource : VisualizerObjectSource { public override void GetData(object target, Stream outgoingData) { string data= target as string; var writer = new StreamWriter(outgoingData); writer.Write(data); writer.Flush(); } } public class MyVirtualizer : DialogDebuggerVisualizer { protected override void Show(IDialogVisualizerService windowService, IVisualizerObjectProvider objectProvider) { var streamReader = new StreamReader(objectProvider.GetData()); string data = streamReader.ReadToEnd(); using (var form = new MyVirtualizerForm(data)) { windowService.ShowDialog(form); } } } The string here is passed to the visualizer and show my own form. It works. But now I want to pass back the modified data from the form to the variable. How do I do that? Edit: I found out that I need to override the TransferData method in VisualizerObjectSource. But in the MSDN is no detail information about how I implement this correctly. Can someone help me please?

  • Pixels - A cry for some insight

    - by CarrotFile
    I'm pretty new to web developing and I'd love some clarification. Although reading more than one book on the topic, I cannot seem to wrap my head around the pixel concept. I encounter problems with this issue when trying to use CSS and pixel units for design that fits different screen sizes. To my understanding a pixel is the most basic unit used by a monitor in order to compose an image on the screen. So if me resolution is 800 by 600, everything on my screen is rendered using those 800*600 basic building blocks. If I were to enlarge my screen resolution, 3 things would accrue: A. The basic image building block(the pixel) would shrink in size B. The pixels would move close together C. Well, more pixels would now be available All these combined lead to a sharper(depending on the viewing distance) and more detail enabling image. Well so far so good. Here is were I start getting lost: To my knowledge a pixel is not a physical, real object. Monitors are not embedded with a few thousand pixels. I am drawn to this conclusion because anyone can change his screen's resolution, making a pixel on his screen bigger or smaller, and adding or subtracting the amount of total pixels on screen. Adding to that, I have herd that different monitors have different pixel densities. For example Apple's retina monitors. Taking all of the above as my knowledge base, These are my questions: If a pixel has no real world constant size, what does comparing different pixel densities matter? Each screen company can define it's own pixel concept and declare the higher density. What does a bigger pixel density mean? Say we take two screens with the same physical dimensions, but with a different pixel density, am I to assert that the main difference would be the larger density screen being able to display a higher max resolution? Or am I to assert that given the same resolution on both monitors, the higher density one would display a sharper, smaller image? If a pixel is not a fixed size within one monitor, is it a fixed size between the same resolution on two different monitors? For example, would two different monitors, set to the same resolution, be comprised of same size, same quantity pixels? I'd love some help (:

  • Optimal video resolution and encoding for recording games for YouTube?

    - by Rookie
    I want to record video from games, therefore I cannot use very large video resolution, but I still want to make the large video view to look as sharp as the original encoded video before upload. I tried to use YouTube's recommended 854x640 resolution, but it wasn't possible with h264 and the encoding software I used (Handbrake) converted it to a width of the nearest multiple of 4, which I think is a limitation of the h264 format. The video I encoded was sharp and fine quality, but when I uploaded it to YouTube, it lost a lot of quality and the preferred large video view looks almost as bad as a 320p video. I tried to wait a few days but it never got sharper (in case it didn't process it completely yet). So, which resolution and encoding options I should use, if I want the large video player to have the sharpest possible video, retaining the original video quality as good as possible? I noticed that recording with 640x480, the video was sharper than with 1280x720, so I'm not sure what im doing wrong here; both were h264. Is it anyhow possible to prevent YouTube from re-encoding the videos? I just wonder how people can make so sharp videos, while mine are all blurry after upload, but before upload they looked fine. I also tried YouTube's suggested bitrates with h264, but it didn't work any better.

  • Font rendering in Firefox is blurry

    - by Mehrdad
    A picture is worth a thousand words... so does anyone know how to fix this font blurriness in Firefox? (You'll need to right-click the picture below go to View Image to view it full-size; it's too small to see anything here.) Note: My other applications (and the Firefox non-client area, as you can see in the screen) are completely fine, so obviously going to System-Appearance and changing the font settings isn't fixing the situation. Edit: Not letting web pages to use their own fonts also doesn't help: See how the upper one is still sharper? Also, Firefox's own menu bar doesn't render the same way as the page content (menu bar below, page content above). They're both Segoe UI:

  • "Progressive" JPEG: Why do many web sites avoid rendering JPEGs that way? Pros, cons?

    - by Chris W. Rea
    When JPEG images are used by a web page, they are typically rendered top-down ... but they can also be rendered using a mode called progressive JPEG, where the image starts out full-size, but blurry, and then gets sharper with successive passes, until it's fully loaded. Progressive loading requires the image have been saved that way. Why don't more web sites use progressive JPEG? What are the drawbacks? Is it simply a lack of tool support, or are these files somehow inferior to traditional top-down rendered JPEG images?

  • What light attenuation function does UDK use?

    - by ananamas
    I'm a big fan of the light attenuation in UDK. Traditionally I've always used the constant-linear-quadratic falloff function to control how "soft" the falloff is, which gives three values to play with. In UDK you can get similar results, but you only need to tweak one value: FalloffExponent. I'm interested in what the actual mathematical function here is. The UDK lighting reference describes it as follows: FalloffExponent: This allows you to modify the falloff of a light. The default falloff is 2. The smaller the number, the sharper the falloff and the more the brightness is maintained until the radius is reached. Does anyone know what it's doing behind the scenes?

  • Drawing scaled emoji icons on iOS

    - by Eimantas
    I'm trying to implement my own emoji icon keyboard and have some problems. I'm trying to draw emoji icons at the same size as on native iOS emoji keyboard, but when doing simple drawing (standard unicode characters like "\ue415") icons always appear at original size. When trying to increase the font - emoji icons stay of the same size. When applying CGAffineTransform for scaling - drawn icons are bigger, but pixelated and blurred. How should I go about drawing emoji icons bigger, but sharper?

  • Core Animation Unwanted Text Sharpening.

    - by dave-gennel
    Whenever I add a layer for Core Animation either from the nib or programatically, the NSTextFields (labels) in my interface get messed up. Here's a screenshot from Apple's BasicCocoaAnimations example. (Look at the text fields on the left, somehow they're drawn sharper than normal) Note that if I add a layer in IB then it also gets messed up in IB itself before I even run my app.

  • resize image without image quality reduction

    - by ali
    In web design , it's usually needed to design an image for example in Photoshop and then use multiple sizes of it. but I don't understand something here : When I resize the image (PNG or JPG) and reduce the dimensions of that in Photoshop , the image quality extremely gets reduced and the edges become messy while resizing the image in a simple software like Microsoft Paint gives a really better output! So what's the reason ? Is there a trick in Photoshop for image resizing which I've missed? Thanks for your help. UPDATE: I resize in this way : image image size , then enter new dimensions , all of checkboxes are checked , and have tried all of resample modes including Bicubic sharper

  • PDF with 200 DPI JPEGs look blurry in viewer

    - by queueoverflow
    I often scan images, and I usually do that as 200 DPI JPEG files. If I look at them in Gwenview (Linux image viewer) the text looks readable, and on 100% it looks perfectly sharp. When I convert them into a PDF, using convert from the Imagick package and open that in Okular or Evince (Linux document viewer) the text looks blurry. I wrote a little script that creates a HTML page with all the images and opens it in the browser. Firefox scales the images a little sharper than the PDF viewers. Firefox JPEGs: Evince PDF Is there any way to get the PDF to scale the images sharply?

  • Need alternative to Accessibility's "Locate Pointer" to visually highlight the mouse.

    - by fred.bear
    Update: See end of quetion: A black-on-white cross-hair/I-bar mouse-pointer is soemtimes hard foe me to spot in amongst black-on-white text. I've tried "Accessibility / Mouse Accessibility / Locate Pointer" .. which will: Show pointer position when Control is presssed It works (to a point), but it does have a notable problem, which renders it inpractical. It has the uncanny side-effect of disallowing all Control key navigation while editing a file/dir name in Nautilus (F2).. Just touching the Control key drops it out of edit mode, which means I can't keyboard paste, move-L/R word etc... So, I'm looking for an alternative. I've tried Compiz's Water Effect, but I need something which is sharper, faster, and localized to the pointer. Compiz's Show Mouse (with fire) is no suitable. I'm really lookingf for an analog of "Accessibility / Locate Pointer": * ie. I hit Control (only).. and it blips a quick visual pulse. UPDATE: I've just realized why I can't find my mouse so often! ... It's because it is isn't there !!! ... Two apps I use a lot, Gedit and Konsole (KDE Terminal; it renders unicode better), ... dissolve the mouse-pointer to invisible after the first key is typed ... and Konsole does it after a few seconds of idle-time... like a video-player option: "hide the mouse".. Well I don't use the mouse much, and I thought it was juse my eyesight (which does rely a lot on Compiz's zoom)... I discovered it when I installed a "novelty" app, called Geyes from gnome-applets ("A goofy set of eyes for the GNOME panel. They follow your mouse.") ... It could follow the mouse better than me! :)

  • Evolution Of High Definition TV Viewing

    - by Gopinath
    The following guest post is written by Rob, who is also blogging on entertainment technology topics on iwantsky.com Gone are the days when you need to squint to be able to see the emotions on the faces of Humphrey Bogart and Ingrid Bergman as the lovers bid each other adieu in the classic film Casablanca. These days, watching an ordinary ant painstakingly carry a leaf in Animal Planet can be an exhilarating experience as you get to see not only the slightest movement but also the demarcation line between the insect’s head, thorax and abdomen. The crystal clear imagery was made possible by the sharp minds and the tinkering hands of the scientists that have designed the modern world’s HDTV. What is HDTV and what makes people so agog to have this new innovation in TV watching? HDTV stands for High Definition TV. Television viewing has indeed made a big leap. From the grainy black and whites, TV viewing had moved to colored TVs, progressed to SD TVs and now to HDTV. HDTV is the emerging trend in TV viewing as it delivers bigger and clearer pictures and better audio. Viewers can have a cinema-like TV viewing experience right in the comforts of their own home. With HDTV the viewer is allowed to have a better viewing range. With Standard (SD) TV, the viewer has to be at a distance that is from 3 to 6 times the size of the screen. HDTV allows the viewer to enjoy sharper and clearer images as it is possible to sit at a distance that is 1.5 or 3 times the size of the screen without noticing any image pixilation. Although HDTV appears to be a fairly new innovation, this system has actually existed in various forms years ago. Development of the HDTV was started in Europe as early as 1940s. However, the NTSC and the PAL/SECAM, the two analog TV standards became dominant and became popular worldwide. The analog TV was replaced by the digital TV platform in the 1990s. Even during the analog era, attempts have been made to develop HDTV. Japan has come out with MUSE system. However, due to channel bandwidth requirement concerns, the program was shelved. The entry of four organizations into the HDTV market spurred the development of a beneficial coalition. The AT&T, ATRC, MIT and Zenith HDTV combined forces. In 1993, a Grand Alliance was formed. This group is composed of researchers and HDTV manufacturers. A common standard for the broadcast system of HDTV was developed. In 1995, the system was tested and found successful. With the higher screen resolution of HDTV, viewing has never been more enjoyable.

  • UIView using Quartz rendering engine to display PDF has poor quality compared to original.

    - by Josh Kerr
    I'm using the quartz rendering engine to display a PDF file on the iphone using the 3.0 SDK. The result is a bit blurry compared to a PDF being shown in a UIWebView. How can I improve the quality in the UIView so that I don't need to rewrite my app to use the UIWebView. I'm using pretty much close to the example code that Apple provides. Here is some of my sample code: CGContextRef gc = UIGraphicsGetCurrentContext(); CGContextSaveGState(gc); CGContextTranslateCTM(gc, 0.0, rect.size.height); CGContextScaleCTM(gc, 1.0, -1.0); CGAffineTransform m = CGPDFPageGetDrawingTransform(page, kCGPDFCropBox, rect, 0, false); CGContextConcatCTM(gc, m); CGContextSetGrayFillColor(gc, 1.0, 1.0); CGContextFillRect(gc, rect); CGContextDrawPDFPage(gc, page); CGContextRestoreGState(gc); Apple's tutorial code actually results in a blurry PDF view as well. If you drop the same PDF into a UIWebView you'll see it is actually sharper. Anyone have any ideas? This one issue is holding a two year development project from launching. :(

  • trying to reenter IT field after a break of over 5 years

    - by josephj1989
    Hello I have had some misfortune in life - I was unwell and had to stay out of work for an extended period of about 5 years.Before that I used to work as an Oracle/Oracle Ebusiness suite consultant (I was charging very good contract rates). But now I am fully recovered ,feeling sharper than ever. But there arent many opportunities in my areas of expertise in a small market like New Zealand and the long absence is no help either. So for the last 5 months I have been training myself in C# ,ASP .NET,WEB technologies like HTML,JQuery,CSS and also SQL Server.I had some previous experience with JAVA and VB .NET (few months). But I am fully confident of my abilities and believe I can hit the ground running given a chance.I used to be an expert with SQL and C language and these skills are portable to SQL Server and C#. Another problem I face is my age- I am over 50. What is your opinion - Am I doing the right thing. Can I get back into an IT career-I am willing to start all over again at a junior level, I am really facing a crisis in my life.

    At this point, I'm thinking of just using CSS 3, esp. since I'm a programmer, but I'd like to do this with Photoshop because I think it's nicer since I'm working with images anyway, among other reasons... Before I move on, my first question is: Is there a place like SuperUser for designers (or for Photoshop-like or questions)? What I Want: I want the icons on http://www.mattdipasquale.com/ to look like those on http://about.me/mattdipasquale. About.me has an outdated Twitter icon and does not have icons for GitHub, StackOverflow, etc. So, although I like the look of their icons, I want to be able to create these icons myself instead of using their versions. What I Have: I have different iphone icons, like the Facebook iPhone icon, Twitter iPhone icon, etc., that I got from iTunes, using Firebug to find the URL of the background image. I opened them up in Photoshop and pressed option + command + i to reduce the image size to 32px x 32px with Bicubic Sharper (best for reduction). I now have a square icon layer. Closing the Gap: In addition to the icon layer, I want to have a clipping-mask layer that will apply the 5px rounded-corners, 1px stroke, and 1px bevel. (Note: I just want to apply effects to the edges of the icon because the gloss and other effects are already encoded in the iTunes image. Also, I'm just guessing about the pixel values, but I want it to look good, like the icons on about.me.) What settings should I use for the blend options to make the icons look good, like iphone icons or those used by about.me? Why a Clipping Mask? The reason I want to use a clipping mask is that I want ease of reproducibility. I want to be able to apply the same styling to other square icon layers by simply replacing the square icon layer and then saving for web. If there is a better way to achieve such ease of reproducibility, please suggest it. I've seen Photoshop iPhone icon templates, but I couldn't figure out how to use them with my own images. Thanks! Matt
