This is a follow-on question to the How do you use ssh in a shell script? question. If I want to execute a command on the remote machine that runs in the background on that machine, how do I get the ssh command to return? When I try to just include the ampersand (&) at the end of the command it just hangs. The exact form of the comman...
Jeff has previously blogged about using the cache to perform "out of band" processing on his websites, however I was wondering what other techniques people are using to process these sorts of tasks? ...
I've had some trouble forking of processes from a Perl CGI script when running on Windows. The main issue seems to be that 'fork' is emulated when running on windows, and doesn't actually seem to create a new process (just another thread in the current one). This means that web servers (like IIS) which are waiting for the process to fini...
Most modern apps provide an interactive way to push a long running operation onto a background queue. I am developing a swing application and I have implemented a simple "framework" to support that. However, I can't help but think that something like that must exist already. I have heard that Netbeans provides that, but I don't want to m...
What's the best way for a running C or C++ program that's been launched from the command line to put itself into the background, equivalent to if the user had launched from the unix shell with '&' at the end of the command? (But the user didn't.) It's a GUI app and doesn't need any shell I/O, so there's no reason to tie up the shell af...
I have several different c# worker applications that run various continuous tasks: sending emails from queue, importing new orders from website database to orders database, making database backups and restores, running data processing for OLTP -> OLAP, and other related tasks. Before, I released these as windows services, but currently I...
Hello, I'm trying to run some commands in paralel, in background, using bash. Here's what I'm trying to do: forloop { //this part is actually written in perl //call command sequence print `touch .file1.lock; cp bigfile1 /destination; rm .file1.lock;`; } The part between backticks (``) spawns a new shell and executes the command...
I am experiencing some weird behavior with localized messages reported from my background worker process in my windows forms application. The application is a setup application with windows forms. The application launches a background worker to perform and IIS reset and then install MSIs. The first time I run the application on a Spani...
Ok so ive got a bitchin swing app going using the "System" look and feel. Now, I want to change the background colour of the main panels to black. Too easy right? UIManager.put("Panel.background", Color.BLACK); Well yeah, except now the controls in the app look stupid, because their 'shadows', for want of a better word, are graduated...
Short of putting a UIWebView as the back-most layer in my nib file, how can I add a repeating background image to an iPhone app (like the corduroy look in the background of a grouped UITableView)? Do I need to create an image that's the size of the iPhone's screen and manually repeat it using copy and paste? ...
We have an application that downloads some files in the background. Our application pops up when an Internet connection is made, and after prompting the user to accept the downloads, we'd like to switch back to the home screen while we do our stuff. We can't work out how to do to this. We can emulate pressing "back" a few times, which s...
I have a large dataset (over 100,000 records) that I wish to load into a DataGridView. The stored procedure that does this can take 10 seconds or more to complete. So far I have a BackgroundWorker preventing the UI from locking up, and have implemented a rudimentary 'Please Wait' dialog. What I'd like to do is somehow populate the Data...
I'm working on a linux machine through SSH (Putty). I need to leave a process running during the night, so I thought I could do that by starting the process in background (with an ampersand at the end of the command) and redirecting stdout to a file. To my surprise, that doesn't work. As soon as I close the Putty window, the process is s...
I have a form with a DIV, 3 INPUTS, each INPUT sits within a LABEL element. I would like to change the background image of the DIV element when focusing on each INPUT. I can't move back up the DOM to fix this with CSS, so could someone suggest a few lines of jQuery please? Thanks ...
I've added a jpg file to the App_localResources folder and in the document properites specified the photo in the Background propery. In the designer it shows up as the background but when i run the page i still get the white page background. ...
In a ASP.NET application that I am writing I need to use connections to a specific server (something like a DB but... different). The connections are quite expensive to establish (a few seconds, literally) so I'm trying to write a pool to improve scalability. Everything is pretty simple, up to one point - recycling old connections. Wit...
Hi! In Latex how can you make the background image to occupy the whole sheet on every page except a certain stripe on the inner side of each page? I can't figure it out. I have a background image I'd like to be seen in whole on each page after printing/binding. Matyi ...
On this page (http://www.bonniesphere.com/blog/elsewhere/) the "li" items have an image instead of a bullet. But the image is centered vertically, and in multi-line entries it doesn't look good. Can anyone tell me if there is something in the CSS that should be changed? Here's the relative code: .entry ul {list-style-type:none;} .entry...
An image set as the background of a DIV is displayed in IE, but not in Firefox. CSS example: div.something { background:transparent url(../images/table_column.jpg) repeat scroll 0 0; } (The issue is described in many places but haven't seen any conclusive explanation or fix.) ...
Hi guys, I have a crazy navigation menu that I have to code. It's kind of tough. Please see the screenshot of the design here: navigation menu screenshot As you can see, the background of the "Home" menu item is quite tough! I can't figure out how to make its background "see-through", meaning it cuts through the dark background and ...
