• Placing an background image with padding in h2 tag

  - by Cedar Jensen

  I want to create a headline (h2) with an image at the right-most area of the bounding box. I have the layout almost right except I can't push the image a little bit to the right of the element's bounding box -- how would I tweak my css so it is displayed correctly? I'm trying to do something like this: [{someHeadLineText}{dynamic space }{image}{5px space}] where the [] indicate the total available width of my content. Html: <div class="primaryHeader"> <h2>News</h2> </div> Css: .primaryHeader h2 { background-color: green; /* the header looks like a box */ color: black; background: transparent url(../images/edit.png) no-repeat right center; border: 1px solid red; } I am placing the image to the right of my h2 element and centered vertically -- but how do I adjust the placement of the background image?

• UIWebView loads a local file for a long time

  - by Knodel

  I have a UIWebView which loads .rtfd.zip files like this: -(void)viewWillAppear:(BOOL)animated { self.title=@"Title"; if(rowPosledovatelnosti==0) { [self loadFile:@"PosledovatelnostiObzie.rtfd.zip"]; } if(rowPosledovatelnosti==1) { [self loadFile:@"Arifmeticheskaya.rtfd.zip"]; } if(rowPosledovatelnosti==2) { [self loadFile:@"Svojstva_Arifmeticheskoj.rtfd.zip"]; } if(rowPosledovatelnosti==3) { [self loadFile:@"Geometricheskaya.rtfd.zip"]; } if(rowPosledovatelnosti==4) { [self loadFile:@"Predel_Posledovatelnosti.rtfd.zip"]; } if(rowPosledovatelnosti==5) { [self loadFile:@"Summa_Geometricheskoy.rtfd.zip"]; } } But on the device it takes some time for the UIWebView to load the content. Is there any way to optimize the loading time?

• Bind texture with pinned mapped memory in CUDA

  - by sjchoi

  I was trying to bind a host memory that was mapped for zero-copy to a texture, but it looks like it isn't possible. Here is a code sample: float* a; float* d_a; cudaSetDeviceFlags(cudaDeviceMapHost); cudaHostAlloc( (void **)&a, bytes, cudaHostAllocMapped); cudaHostGetDevicePointer((void **)&d_a, (void *)a, 0); texture<float, 2, cudaReadModeElementType> tex; cudaBindTexture2D( 0, &tex, d_a, &channelDesc, width, height, pitch); Is it recommended that you used pinned memory and just copy it over to device memory that is bind to texture?

• Is it possible to install IDLE on Python 2.5 and Ubuntu

  - by broiyan

  Ubuntu Software Center offers versions of IDLE numbered 2.6 and upwards. If I have to use Python 2.5 (because of Google App Engine compatibility), will it be possible to still use IDLE? I am of course assuming that the there is some necessity for the IDLE version number to be the same as the Python version number. Presently, my invocations of IDLE fail because of _tkinter not being found. Likewise it is not found when I try to do an import _tkinter interactively. I then proceeded to install Tcl and Tk and python-tk and one of the IDLE versions being offered (none were labelled 2.5) but _tkinter still does not get imported.

• glDrawElements allocating memory and not releasing it

  - by Joshua Weinberg

  Using OpenGLES 1.1 on the iPhone 3G (device, not simulator), I do normal drawing fun. But at points during the run of the application I get giant memory spikes, after a lot of digging with instruments I have found that it is glDrawElements that is grabbing the memory. The buffer being allocated is 4 meg, which to me means its loading a texture into RAM, which I guess could be valid, but its never releasing this buffer, and is allocating multiple of them. How do I make sure that these buffers that GL is creating get destroyed, instead of just hanging around?

• Surely there is a better grid than DataGrid for the .NET Compact Framework...

  - by PavelR

  Having spent a couple of days wrestling with DataGrid in .NET CF, especially controlling the look and feel, I'm looking for alternatives. I don't mind purchasing a solution. I'm looking for Redistributable to our enterprise customers. We control the hardware so it doesn't have to work perfectly on every device. Display strings and numbers in columns with headings. Scrollable, but no paging. Don't row editing. Need to add and delete rows. User re-sizable column widths, and a way to persist that. Work with .NET CF 2.0 or 3.5 on Windows CE 6.0 Any suggestions on grids or toolkits?

• ACTION_MY_PACKAGE_REPLACED not received

  - by Ton

  I am using ACTION_MY_PACKAGE_REPLACED to receive when my app is updated or resinstalled. My problem is that the event is never triggered (I tried Eclipse and real device). This is what I do: Manifest: <receiver android:name=".MyEventReceiver" > <intent-filter android:priority="1000" > <action android:name="android.intent.action.ACTION_MY_PACKAGE_REPLACED" /> </intent-filter> </receiver> Code: public class MyEventReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { if ("android.intent.action.ACTION_MY_PACKAGE_REPLACED".equals(intent.getAction())) { //Restart services } } } This code is simple, in real one I used other events like BOOT_COMPLETED and others, and they work but ACTION_MY_PACKAGE_REPLACED. Thanks.

• Received memory warning and app crashes - iphone

  - by Anand Gautam

  I am creating an app using ARC but my app is crashing due to Received memory warning. The App is working fine in simulator. But in case of iphone device, If i run the app for few minutes then on doing anything, the app crashes straightaway. I have checked my app by xcode instrument. My app folder size is 6 MB but all memory allocation is showing 63 MB on xcode instrument. Because of this reason, presentViewController-Animated-Completion is getting slow during navigation. Does anyone have any solution why this is happening?

• Avoid copying of data between user and kernel space and vice-versa

  - by bala1486

  Hello, I am developing a active messaging protocol for parallel computation that replaces TCP/IP. My goal is to decrease the latency of a packet. Since the environment is a LAN, i can replace TCP/IP with simpler protocol to reduce the packet latency. I am not writing any device driver and i am just trying to replace the TCP/IP stack with something simpler. Now I wanted to avoid copying of a packet's data from user space to kernel space and vice-versa. I heard of the mmap(). Is it the best way to do this? If yes, it will be nice if you can give links to some examples. I am a linux newbie and i really appreciate your help.. Thank you... Thanks, Bala

  - by Peter G Mac.

  So I purchased a computer recently and have been trying to customise the display. Radeon 6800 series Ubuntu 10.10 I have three 22inch 1080P lcd monitors that are mounted together. Everything is working smooth. How do I get the 'big-desktop' display where I have one enormous display across all monitors? Linux - ATI Catalyst Control Center 11.2 does not give me an option to 'group' my profiles like the pictures on their site show with Windows. I have been searching all over for help. Much Obliged, -Peter

• Limit size of cache directory.

  - by M.A. Cape

  I have some questions about the cache directory in android. Does anyone knows the limit for each app's cache directory? Also what will happen if there is not enough disk space to cache data? All I know is when the device runs low on storage, the files here (cache directory)will be the ones that get deleted first and each app has its own cache directory. Now, are the files of other app's cache directory will be cleared to accommodate my app's request to add files in the cache dir when there is not enough storage?

• Scale an image every time it collide with another

  - by jean mayot

  here is my code : -(void)collision{ if(CGRectIntersectsRect(imageView.frame,centre.frame)){ imageView.alpha=0; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:1.0f]; centre.transform=CGAffineTransformMakeScale(1.3, 1.3); [UIView commitAnimations]; } } When imageView collide with centre centre become bigger. my problem is that when "imageView" collide with "centre" a second time the animation doesn't work. I want to make centre bigger and bigger and bigger every time imageView collide with center, but it become bigger just one time . Sorry for my english I'm french :/ How can I solve this please ?

• How do I get the server hostname from a mounted directory with cocoa/obj-c?

  - by Andrew

  Currently when I open a file with my program I can select files on a server by clicking on the server name in the sidebar in an NSOpenPanel and then selecting the file. No problem, this works fine for using the file as long as the shared directory is mounted. I get a path like "/Volumes/SHARENAME/filename.bla". My question is how do I get the server hostname of the computer it came from. For instance, if I clicked on the device with name SERVERNAME under "Shared" in the NSOpenPanel how do I get SERVERNAME from "/Volumes/SHARENAME/filename.bla". I have looked at quite a bit of documentation and have been unable to find a solution for this problem. Any help toward this will be greatly appreciated. Thank you.

• C# - How to make a custom installer for games, etc?

  - by Dodi300

  Hello. Can anyone tell me how to create a custom installer to 'install' games. I say custom meaning I don't want the user to have the option where the game is installed. I want it to be a straight forward process, maybe with just one loading bar. The program I'm developing is a 'center' for game playing, which includes a community and other features, such as a timer that records how long a game is played for. I just thought that installing each game in one place, with a simple installer would make the program easier to use. It also will allow me to do other features as the games will all be installed in one place. No need for the user to specify where the game is installed. Would this be possible? Thanks.

• Using protocol buffers for a comprehensive data strategy for Windows Mobile devices

  - by Steve

  I have started reading some of the posts related to protocol buffers. The serialization method seems very appropriate for the transfer of data to and from web servers. Has anyone considered using a method like this to save and retrieve data on the mobile device itself? (i.e. a replacement for a traditional database / orm layer) Where would the data be persisted? How would the data be queried? Would it make sense to store the data in a traditional database (SqlCE or SqlLite) with a few "searchable" columns and then one column for the serialized data? Thoughts? Am I out on a limb here? Thank you!

• Finding all points common to two circles

  - by Dustin I.

  In Python, how would one find all points common to two circles? For example, imagine a Venn diagram-like intersection of two (equally sized) circles, with center-points (x1,y1) and (x2,y2) and radii r1=r2. Additionally, we already know the two points of intersection of the circles are (xi1,yi1) and (xi2,yi2). How would one generate a list of all points (x,y) contained in both circles in an efficient manner? That is, it would be simple to draw a box containing the intersections and iterate through it, checking if a given point is within both circles, but is there a better way?

• calculating a gps coordinate given a point, bearing and distance

  - by user530509

  Hello, I have a problem which draws my back in some project for some time now. Im basically looking to trap a polygon using x,y points drawn by some script ive written. lat1,lon1 are the center gps cords of the polygon and im looking for its surrounding polygon. here is a part of my code in python: def getcords(lat1,lon1,dr,bearing): lat2=asin(sin(lat1)*cos(dr)+cos(lat1)*sin(dr)*cos(bearing)) lon2=lon1+atan2(sin(bearing)*sin(dr)*cos(lat1),cos(dr)-sin(lat1)*sin(lat2)) return [lat2,lon2] my input goes like this: lat1,lon1 - are given in decimal degrees. -dr is the angular computed by dividing the distance in miles by the earth's -raiuds(=3958.82) -bearing between 0-360 degrees. however for the input getcorsds1(42.189275,-76.85823,0.5/3958.82,30) i get [-1.3485899508698462, -76.8576637627568], however [42.2516666666667,-76.8097222222222] is the right answer. as for the angular distance i calculate it simply by dividing the distance in miles by the earth's raiuds(=3958.82). anybody?

• How to access USB ports in java

  - by Petezah

  Hi I'm trying to write a java application that accesses the usb ports to some read and writes to a device connected through usb. The problem I face is that I don't know what exactly to use in java to do such a thing. I searched online a found something called jusb but all the post seem fairly old. Currently I'm using the RXTX libraries but I sometimes run into some sync error. When I use C# to do the equivalent it requires far less code and I don't face any of the same sync error. My question is there anything built into the latest version of the JRE I can use to access the usb ports that is just as easy as the equivalent C# code? Sorry if the question isn't too clear, I'm fairly noob with coding usb IO.

• What parameters should I use in a Google Maps URL to go to a lat-lon?

  - by xpda

  I would like to produce a url for Google Maps that goes to a specific latitude and longitude. Now, I generate a url such as this: http://maps.google.com/maps?z=11&t=k&q=58 41.881N 152 31.324W The resulting map comes up with a round "A" balloon pointer, which seems to point to the nearest named object, and a green arrow, which points to the lat-lon. Sometimes, as in this example, the "A" pointer is centered and is far enough away that you cannot see the pointer to the lat-lon. (Zoom out to see both pointers in this example. The "A" pointer is in the center of Alaska, while the lat-long pointer is on Kodiak Island.) Are there some parameters I can use in the Google Maps URL that will produce a single pointer to a designated lat-lon? (This loads in a separate window. It is not embedded.)

• Android and Kernel-Modules...

  - by Nils Pipenbrinck

  So - Android is build on top of a stripped down linux system. Most of the convenient utilities are missing but all the basics are there. I can call insmod and rmmod. No problem. But where do kernel-modules and firmware files reside? I can't find any. there is no /lib/modules in the standard distribution. Problem: I need modules. For sure don't want to compile support for each and every usb-device in the world into the linux-kernel. Where should I put them?

• Alternate way to create a clone of a UNIX System

  - by Spirit

  THE STORY: (If you don't like to read much, down below is the question :) ) Where I work we have two HP RP2470 servers same hardware same number of hard drives same everything :). One of them is a production server and runs HP-UX 11.00. The poor ba***rd hasn't been turned off for years and now I have to make a clone of it on the other server - just in case, for redundancy. The problem is simple (or not simple) as I have to make the the other server exactly the same. However the old version of OS (UX 11.00 is a history now) and the old software running on it, have made my task almost impossible. On the production server there is also a cloning/recover utility Ignite-UX. I tried many times to create a recovery tape with it. Then when I load the tape on the backup server, it succeeds with the loading of the tape (no errors no warnings) but on the next restart it fails to load the OS :S and drops into HP`s ISL prompt. --- THE QUESTION: Is there an alternate way to create a clone of the Unix System? The environment is: 1. 2x HP RP2470 Servers (non-Intel), same hardware, same number od HDDs (two each of them) same everything. 2. OS running: HP-UX 11.00 The production server has to be cloned without downtime - sadly :( as I hope that they will reconsider on this one For example (like on Windows platforms), if you try to copy an entire HDD with Windows inside on another HDD, and then put that HDD on another PC it will still work, as long as the hardware is the same. Can I do something like that with a Unix system? Can I somehow COPY the contents of the entire HDD, put those on another HDD, and then just load the HDD into the other server? (If you haven't read the story the servers are exactly the same) Will it work? Can it be done with ordinary commands like cp or dump or something like that? Does any one have a similar experience? --- UPDATE: 26.01.2012 NOTE: The update is related to "The Story". If you haven't read that part then you can skip this update.

• Unwanted virtual keyboard in Blackberry app

  - by matkas

  I have developed a Blackberry app for the 4.5 os series. It works fine on all device except on the storm 1 (storm2 untested). The problem (on the storm) is that the main screen of my application (and all other screens in fact) is shown with the virtual keybord. But there is no text field displayed on the screen that would justify the VK to show up. I have bitmap fields and button fields only on that screen. The use of a single program for all devices (4.5 and up) is seriously preferred. What is causing the VK to show up and what can I do to prevent it (in JDE 4.5)?

• Adobe Livecycle Designer 7 Text Field Issue

  - by MachinationX

  I have a form in a large box, to be filled in by the user with up to 2500 characters. Currently, the cursor starts in the vertical center of the box and I would like: a) The cursor to start at the top left of the field instead of the middle left, so that there is no whitespace above the user's entered text. or b) Somehow enabling a field that expands to fit its text to expand as the text is being entered. As far as I can tell, text fields set to expand to fit the text inside only expand once the user has taken their cursor off the field. Thanks for your help!

• Formula for producing a CGRect for a UIScrollView, that displays a UIImage in scaled to fit way

  - by RickiG

  Hi I am loading in images with varying sizes and putting them in UIScrollViews, all the images are larger than the UIScrollView. The user can scroll and zoom as they please, but initially I would like for the image to be centered and scaled so the largest side of the image aligns with the edge of the scrollView, i.e. if the picture is in landscape I would like to size and scale it so that the left and right side goes all the way to the edge of the UIScrollVIew and vice versa I found a formula in a utility function in the Programming guide but it does not quite fit my needs. My approach is to use: CGrect initialPos = ? [self.scrollView zoomToRect:initialPos animated:YES]; I know the size of my scrollView and the size of my image, what I need to figure out is the scale and CGRect to apply to the scrollView to center and size my image. Hope someone can help out:) Thanks

• Standalone jQuery "touch" method?

  - by dclowd9901

  So, I'm looking to implement the ability for a plugin I wrote to read a touch "swipe" from a touch-capable internet device, like an iPhone, iPad or android. Is there anything out there? I'm not looking for something as full as jQtouch, though was considering reverse engineering the code I would need out of it. Any suggestions on the best way to approach this? A snippet of code already available? Addendum: I realize in hindsight the solution won't strictly be jQuery, as I'm pretty sure there aren't any built-in methods to handle this. I would expect standard Javascript to find itself in the answer.
