• LED Monitor brightness

  - by Yuval

  I am in the market for a new monitor. I've been looking around and it seems that the general brightness for monitors is between 250-320 cd/m2. After hours of searching, I narrowed it down to the LG W2453V-PF vs. the LG E2350V-SN The W2453V-PF is not LED backlit yet it has a brightness level of 310 cd/m2 and a response time of 2ms. The E2350V-SN, on the other hand, has a brightness level of 250 cd/m2 and a response time of 5ms but it is LED backlit. My questions are, looking at these overall specs: Which monitor is better? What makes LED backlight better? Is the LED backlight worth the decreased brightness level? Thanks! p.s. if you have any other comparable monitor suggestions (that are not samsung - I read their customer service is absolutely terrible), feel free to share. thanks!

• Android - Using PreferenceScreen to display and save settings to/from ContentProvider

  - by Donal Rafferty

  I have my own custom Content Provider that loads a datasbase which contains the settings information for my application. I load the settings from the ContentProvider on the creation of my Settings activity. My Settings activity is made up of a PreferenceScreen and Dialog based EditText's. The following code shows how I use the preference screen and edit texts. So as you can see from the first image this works and displays the menu with the information underneath. The problem is in image two, when I click on a choice in the menu the dialog pops up but it is empty, I would like to be able to load the data from my content provider into the edit text in the dialog, so in image one it shows "Donal" as the user name so in image two "Donal" should also appear in the edit text in the dialog. I would also like to be able to listen to the OK button in the dialog so when a user changes a setting I can update the data in my content provider. Can anyone help me with what I'm trying to do? Code // Root PreferenceScreen root = getPreferenceManager().createPreferenceScreen(this); // Dialog based preferences PreferenceCategory dialogBasedPrefCat = new PreferenceCategory(this); dialogBasedPrefCat.setTitle(R.string.dialog_based_preferences); root.addPreference(dialogBasedPrefCat); // Edit text preference EditTextPreference editTextPref = new EditTextPreference(this); editTextPref.setDialogTitle(R.string.dialog_title_edittext_preference); editTextPref.setKey("edittext_preference"); editTextPref.setTitle(R.string.title_edittext_preference); editTextPref.setSummary(name); dialogBasedPrefCat.addPreference(editTextPref); Image One Image Two

• Creating a closeable tab in Mono/GTK

  - by Chumpy

  I'm trying to create new GTK Notebook tabs that contain both a name (as a Label) and a close button (as a Button with an Image) with the following code: Label headerLabel = new Label(); headerLabel.Text = "Header"; HBox headerBox = new HBox(); Button closeBtn = new Button(); Image closeImg = new Image(Stock.Close, IconSize.Menu); closeBtn.Image = closeImg; closeBtn.Relief = ReliefStyle.None; headerBox.Add(headerLabel); headerBox.Add(closeBtn); headerBox.ShowAll(); MyNotebook.AppendPage(childWidget, headerBox); This seems to work just fine; however, the button is about 1.5 - 2 times the size is needs to be, so there is a lot of extra space around the image inside the button. Having looked at remove inner border on gtk.Button I now see that the culprit is the "inner-border" style property of the GtkButton, but (being new to GTK) I can't seem to figure out how to override its value. Is there some method of doing this that I'm missing? I don't have any reservations about not using a Button/Image combination, so any more obvious suggestions are welcome. Note: I have seen the suggestion in the linked question to use an EventBox, but I was not able to add the Relief and mouseover effects to that Widget.

• Silverlight: Download local files with WebClient

  - by David

  The directory structure of my Silverlight project is like the following: \Bin - MainModule.xap - \Images --- Image1.png --- Image2.png - \Modules --- SubModule.xap I want to be able to run it through either a web server or through Visual Studio directly (for debugging purposes I want to bypass content downloading). In my media loading code I do something like the following: if (runningLocally) { var bitmapImage = new BitmapImage(); bitmapImage.UriSource = new Uri("Images/Image1.png", UriKind.Relative); var image = new Image(); image.Source = bitmapImage; } else { WebClient wc = new WebClient(); wc.OpenReadCompleted += (s, e) => { var bitmapImage = new BitmapImage(); bitmapImage.SetSource(e.Result); var image = new Image(); image.Source = bitmapImage; }; wc.OpenReadAsync(new Uri("Images/Image1.png", UriKind.Relative)); } This works for images but I also have sub-modules which are just assemblies housing UserControls. Since Silverlight has no ability to read disk I've resigned myself to the fact that I'm going to have to "download" the XAPs I need whether I'm running locally or not. Problem is if I run the project locally and try to use a WebClient to download a XAP I get an exception: System.Net.WebException: An exception occurred during a WebClient request. ---> System.NotSupportedException: The URI prefix is not recognized. Is there any way (WebClient or otherwise) I can get to my sub-module XAPs when running the Silverlight project directly rather than hitting a web server?

• How can I create a custom UIToolbar like component in a UITableViewController?

  - by Tony

  I have a UITableViewController. I want a "toolbar-ish" component at the bottom. I started by using a background image and a button. In interface builder, I added them to the bottom of the iPhone screen. The problem I ran into was that the background image and button scrolled with the table. I obviously need this fixed at the bottom. Not finding too much direction online, I decided to customize a UIToolbar to look how I want since the position is fixed by default. In my initWithNibName for my UITableViewController, I have: UIImage *shuffleButtonImage = [UIImage imageNamed:@"shuffle_button.png"]; NSArray* toolbarItems = [NSArray arrayWithObjects: [[UIBarButtonItem alloc] initWithImage:shuffleButtonImage style:UIBarButtonItemStylePlain target:self action:@selector(push:)], nil]; [toolbarItems makeObjectsPerformSelector:@selector(release)]; self.toolbarItems = toolbarItems; The problem I am running into now is that the "shuffleButtonImage" is not showing up properly. The shape of the button shows up fine but it is colored white and therefore does not look like the image. Does anyone know why a "white image" would be showing instead of the actual image? Also does it sound like a good idea to customize a UIToolbar or is there a simple way to ensure a fixed position "toolbar-ish" component. To reiterate - my "toolbar-ish" component only needs to be one button at the button of my UITableView. The single button has a gradient color background that I create with an image.

• Mysql Algorithm for Determining Closest Colour Match

  - by buggedcom

  I'm attempting to create a true mosaic application. At the moment I have one mosaic image, ie the one the mosaic is based on and about 4000 images from my iPhoto library that act as the image library. I have already done my research and analysed the mosaic image. I've converted it into 64x64 slices each of 8 pixels. I've calculated the average colour for each slice and assertain the r, g, b and brightness (Luminance (perceived option 1) = (0.299*R + 0.587*G + 0.114*B)) value. I have done the same for each of the image library photos. The mosaic slices table looks like so. slice_id, slice_image_id, slice_slice_id, slice_image_column, slice_image_row, slice_colour_hex, slice_rgb_red, slice_rgb_blue, slice_rgb_green, slice_rgb_brightness The image library table looks like so. upload_id, upload_file, upload_colour_hex, upload_rgb_red, upload_rgb_green, upload_rgb_blue, upload_rgb_brightness So basically I'm reading the image slices from the slices table into PHP and then pulling out the appropriate images from the library table based on the colour hexs. My trouble is that I've been on this too long and probably had too many energy drinks so am not concentrating properly, I can't figure out the way to pick out the nearest colour neighbor if the appropriate hex code doesn't exist. Any ideas on the perfect query? NB: I know pulling out the slices one by one is not ideal however the mosaic is only rebuilt periodically so a sudden burst in the mysql load doesn't really bother me, however if there us a way to pull the images out all at once that would also be a massive bonus.

• Setting alias in Windows PowerShell

  - by westsider

  In PowerShell, I type: PS C: sal cdp "cd 'C:\Users\ec\Documents\Visual Studio 2010\Projects'" I get no error from this, and PS C: gal cdp shows definition as: cd 'C:\Users\ec\Documents\Visual Studio 2010\Projects' But, when I try to use cdp, I get this: Cannot resolve alias 'cdp' because it refers to term 'cd 'C:\Users\ec\Documents\Visual Studio 2010\Projects'', which is not recognized as a cmdlet, function, operable program, or script file. Verify the term and try again. At line:1 char:4 + cdp <<<<  + CatergoryInfo   : ObjectNotFound (dsp:String) [], CommandNotFoundException  + FullyQualifiedErrorId   : AliasNotResolvedException I am guessing that this is trivially easy. So I apologize in advance if that is the case. I have googled and googled and have also read through Windows PowerShell Cookbook.

• JQuery fadeIn() moving other CSS elements on fadeIn()

  - by Infiniti Fizz

  Hi, I've just been learning some jQUery to get a basic image gallery going on a website I'm creating for a hotel but it's currently not going to plan. I've got it so the arrows will cycle through images (no animation yet) but I decided that the arrows should fade in when the image is hovered over and fade out when not but this is messing up the CSS somehow. The arrows start faded out by calling: $('.arrowRight').fadeOut(0);$('.arrowLeft').fadeOut(0); at the start of the jQuery ready() function. This is fine, but when you hover over the image and the arrows fade in, the image shifts to the right and I don't know why. I suppose it could be because the left arrow now fading in means it is getting pushed over by it but the arrow has the following css: position:relative; top: -90px; left: 25px; Should a relative element be able to alter a normal element's position? If you need to try it out, just hover over the large (placeholder) image and they image will jump across when the arrows fade in and jump back when they fade out. Any ideas why this is happening? I'm a jQuery noob. Here is a link to the page: BeanSheaf Hotel Temporary Space Thanks for your time, InfinitiFizz

• 3x3 Sobel operator and gradient features

  - by pithyless

  Reading a paper, I'm having difficulty understanding the algorithm described: Given a black and white digital image of a handwriting sample, cut out a single character to analyze. Since this can be any size, the algorithm needs to take this into account (if it will be easier, we can assume the size is 2^n x 2^m). Now, the description states given this image we will convert it to a 512-bit feature (a 512-bit hash) as follows: (192 bits) computes the gradient of the image by convolving it with a 3x3 Sobel operator. The direction of the gradient at every edge is quantized to 12 directions. (192 bits) The structural feature generator takes the gradient map and looks in a neighborhood for certain combinations of gradient values. (used to compute 8 distinct features that represent lines and corners in the image) (128 bits) Concavity generator uses an 8-point star operator to find coarse concavities in 4 directions, holes, and lagrge-scale strokes. The image feature maps are normalized with a 4x4 grid. I'm for now struggling with how to take an arbitrary image, split into 16 sections, and using a 3x3 Sobel operator to come up with 12 bits for each section. (But if you have some insight into the other parts, feel free to comment :)

• How to remove a partition on a USB drive?

  - by Nathan Long

  I got a free promotional USB stick that I want to format for my own purposes. When I inserted it, it automatically opened a browser and launched a web site. I have since disabled autoplay on this computer so that nothing launches when the stick is inserted. But it still shows up as two separate drives, and one of them is a "CD Drive" that I can't format. How can a USB stick contain a "CD Drive?" And more to the point, how can I remove this partition using Windows XP or Ubuntu? Update I previously asked for an XP solution, but finding none, I have tried Ubuntu, also without success. Gparted doesn't see the "CD" portion as a device at all, and from bash, any chmod changes I try tell me that the file system is read-only. Any ideas?

• Does the Windows "Sources" folder need copied to C: like the "i386" folder did?

  - by James Watt

  On all flavors of Windows prior to Windows Vista, the Windows install CD contained a folder called i386. After installing Windows, this folder is suppose to be copied to the C: drive. Once the folder has been copied, if user is ever installing a program or windows updates that require the Windows install CD, it will retrieve the files from the hard drive INSTEAD of prompting for the Windows CD. On new versions of Windows, including Windows Vista, Windows 7, Server 2008 and Server 2008 R2, the i386 folder has been renamed to "sources". Should this folder be copied to the hard drive? Or do the new versions of Windows work differently (i.e. by installing all features on the hard drive to eliminate the need for ever prompting the user to insert their disc.) It does not hurt to copy the sources folder, so I have been doing it. But if I could eliminate time wasted it would make installations faster which helps my customers' bottom line.

• CSS - Inheriting layered background images

  - by NNN

  CSS3 supports multiple background images, for example: foo { background-image: url(/i/image1.jpg), url(/i/image2.jpg); } I'd like to be able to add a secondary image to an element with a class though. So for example, say you have a nav menu. And each item has a background image. When a nav item is selected you want to layer on another background image. I do not see a way to 'add' a background image instead of redeclaring the whole background property. This is a pain because in order to do this with multi-backgrounds, you would have to write the base bg image over and over for each item if the items have unique images. Ideally I'd be able to do something like this: li { background: url(baseImage.jpg); } li.selected { background: url(selectedIndicator.jpg); } And have li.selected's end result appear the same if I did: li.selected { background: url(baseImage.jpg), url(selectedIndicator.jpg); } Update: I also tried the following with no luck (I believe backgrounds are not inherited..) li { background: url(baseImage.jpg), none; } li.selected { background: inherit, url(selectedIndicator.jpg); }

• Android : Bitmap save to location

  - by Chrispix

  I am working on a function to download an image from a web server, redisplay it on the screen, and if the user wishes to keep the image, save it on the SD card in a certain folder. Is there an easy way to take a bitmap and just save it to the SD card in a folder of my choice? My issue is that I can download the image, display it on screen as a Bitmap. The only way I have been able to find to save an image to a particular folder is to use FileOutputStream, but that requires a byte array. I am not sure how to convert (if this is even the right way) from Bitmap to byte array, so I can use a Fileoutput stream to write the data. The other option I have is it use MediaStore : MediaStore.Images.Media.insertImage(getContentResolver(), bm, barcodeNumber + ".jpg Card Image", barcodeNumber + ".jpg Card Image"); Which works fine to save to SD card, but does not allow you to customize the folder. Any assistance would be very much appreciated. Thank you in advance.

• Looking for QNX compatible server hardware

  - by Sergey Sobolev

  Can you help me to find compatible modern server for QNX, please? This is quite rare OS, so most of the hardware vendors do not have compatibility information. It would be very helpful to me if you can do the following: Download iso http://www.qnx.com/download/download/19602/qnxsdp-6.4.1-x86-200905201802-nto.iso burn to cd Start from cd press F2 - try from CD start Utilities/Terminal run sloginfo /tmp/sloginfo.log; get_hw_info; pci -vvv /tmp/pci-vvv.log send logs from /tmp/ to [email protected] with system model/build I will summarize results afterwards and post them here. I'm especially interested in Fujitsu RX100 S5 as it looks like one of the most compatible servers with frontally accessible HDDs.

• Single-player pong game

  - by Jam

  I am just starting out learning pygame and livewires, and I'm trying to make a single-player pong game, where you just hit the ball, and it bounces around until it passes your paddle (located on the left side of the screen and controlled by the mouse), which makes you lose. However, I keep getting the error: "Cannot have more than on Screen object", which I can find no references to online really, and I can't make sense of it. I want to eventually make the game more complicated, but I need to make it work first. Help please!

• How to add favicon.ico in ASP.NET site

  - by Tapas Bose

  The solution structure of my application is: Now I am in Login.aspx and I am willing to add favicon.ico, placed in the root, in that page. What I am doing is: <link id="Link1" runat="server" rel="shortcut icon" href="../favicon.ico" type="image/x-icon" /> <link id="Link2" runat="server" rel="icon" href="../favicon.ico" type="image/ico" /> Also I have tried: <link id="Link1" runat="server" rel="shortcut icon" href="favicon.ico" type="image/x-icon" /> <link id="Link2" runat="server" rel="icon" href="favicon.ico" type="image/ico" /> But these aren't working. I have cleared the browser cache but no luck. What will be the path to the favicon.ico from: Login.aspx Site.master Thank you. The login page's URL: http://localhost:2873/Pages/Login.aspx and the favicon.ico's URL: http://localhost:2873/favicon.ico. I am unable to see the favicon.ico after changing my code as: <link id="Link1" rel="shortcut icon" href="/favicon.ico" type="image/x-icon" /> <link id="Link2" rel="icon" href="/favicon.ico" type="image/ico" />

• sudo/su command for Red Hat Server 5.4

  - by rednaxela

  Without going into too much detail, I need to execute one linux command on redhat with root user access. Red Hat Server 5.4 does not recognise the sudo command. The command su can be used to switch to the root user on redhat, but su cannot be done in one line. For example the command: su ; cd opt/storage/RootAccessFolder will not work because this only switches you to root, then executes the cd command once you have logged out from the root user. I guess what i'm looking for is like a.. sudo cd opt/storage/RootAccessFolder but I say again, sudo doesn't work. Any ideas?

• Keyword 'this'(Me) is not available calling the base constructor

  - by serhio

  In the inherited class I use the base constructor, but can't use class's members calling this base constructor. In this example I have a PicturedLabel that knows it's own color and has a image. A TypedLabel : PictureLabel knows it's type but uses the base color. The (base)image that uses TypedLabel should be colored with the (base)color, however, I can't obtain this color: Error: Keyword 'this' is not available in the current context A workaround? /// base class public class PicturedLabel : Label { PictureBox pb = new PictureBox(); public Color LabelColor; public PicturedLabel() { // initialised here in a specific way LabelColor = Color.Red; } public PicturedLabel(Image img) : base() { pb.Image = img; this.Controls.Add(pb); } } public enum LabelType { A, B } /// derived class public class TypedLabel : PicturedLabel { public TypedLabel(LabelType type) : base(GetImageFromType(type, this.LabelColor)) //Error: Keyword 'this' is not available in the current context { } public static Image GetImageFromType(LabelType type, Color c) { Image result = new Bitmap(10, 10); Rectangle rec = new Rectangle(0, 0, 10, 10); Pen pen = new Pen(c); Graphics g = Graphics.FromImage(result); switch (type) { case LabelType.A: g.DrawRectangle(pen, rec); break; case LabelType.B: g.DrawEllipse(pen, rec); break; } return result; } }

• Wireless driver not detected by Windows 8

  - by rksh

  I've a problem in my wireless driver on windows 8. I bought a new X500L Asus laptop and installed windows 8 on it. However the driver CD I got with the laptop doesn't support my laptop. The CD says it's designed for Windows 8.1. I tired finding Wireless driver model and finding driver online and installing and that hasn't worked either, the wireless driver is shown at the device manager as not installed. I tired live booting the computer with a live CD of Linux and that also doesn't pick up my wireless driver. Can anyone tell me how to fix it? Thanks
