  • 'Singleton' application - or let the user only launch one instance of a program at the time

    - by Disco
    I'm running a few linux desktops; mainly for kids (yeah, trying to teach them the right OS at early stage) (running Ubuntu 10.10, Gnome) The problem is that they found very funny to make their workstations (actually, old 512 Mb pentium 4) by launching thousands of firefox instances. I'm looking for a way to restrict them to launch 'N' instances of a particular application. Haven't figured yet how. Thought of a monitoring daemon but I think that would be too ressources hungry. Any idea of a script/trick to achieve this ? Note: i might have 1-2 level of users (the kids, and the more grown up kids) so i have also to limit per user; something like user1: 3firefox, user2: 2firefox instances.

  • Set creation and update time with Hibernate in Xml mappings

    - by Marco
    Hi, I'm using Hibernate with Xml mappings. I have an entity that has two fields creationDate and updateDate of type timestamp, that have to be filled with the current UTC time when the entity is persisted and updated. I know about the existence of the @PrePersist and @PreUpdate annotations, but i don't know how to use their equivalent in my Xml mappings. Again, i was wondering if Hibernate somehow supports natively the update and creation time set. Thanks

  • How to time Java program execution speed

    - by George Mic
    Sorry if this sounds like a dumb question but how do you time the execution of a java program? I'm not sure what class I should use to do this. I'm kinda looking for something like: //Some timer starts here for (int i = 0; i < length; i++) { // Do something } //End timer here System.out.println("Total execution time: " + totalExecutionTime); Thanks

  • Print same text several time to one page

    - by RiaD
    I have a odt(or pdf, or ps) file. [Really I have odt, but I can easily convert it], it consist of 1 page. No I want to print it to another pdf 4 times to 1 page. There is an option pages per side, so If I copy-paste 4 times my document and set this option to 4 I'll have my expected result. But I want to do it without copy-paste because it's quite annoying to copy-and-paste before each printing. Is it simpler way?

  • Are IIS services closed after some time?

    - by mafutrct
    I'd like to host a WCF web service in IIS. The service should keep a certain set of data all the time, it must never be lost. My colleague told me this is impossible because IIS closes down the service after a certain time (I assume without any activity). Is that true? How do I prevent that behavior? In case it matters, both IIS 6 and 7 are available.

  • Real-time Image Resize, Cropping and Caching Server Product

    - by Elijah
    I'm investigating what products are out there that will allow you to request images through a HTTP API in arbitrary image sizes. The server would behind a CDN but would still need to be able to handle a fair bit of traffic and be possibly load-balanced. I've been tasked with writing such a service, but I wanted to do some due diligence to see what commercial or open source solutions are out there. Google has not been particularly helpful. It may be because I have been searching for the wrong term. Third-party sites and services are out of the question because of corporate policies.

  • Controlling IFrame load time

    - by Venki
    Is there a way for me to control the load time of IFrames within my page. Consider the case where I have an HTML page, within which there are 2 IFrames being rendered. Is it possible to control the time it takes for the IFrames to load? In the sense, if the IFrame does not load within 10 secs, then I want to abort the loading of the iFrame.

  • Design-time properties in IB?

    - by Krumelur
    Coming from the .NET world into ObjC and iPhone development, I'm used to providing design-time support for my UI classes. For example, say that I have a custom button class with a color property. I want to be able to set this color in design time from IB. How can I accomplish this? Is it even possible? Worth the effort?

  • Network folder image thumbnails taking long time to load

    - by Steve
    Our internal network folder can take up to 5 seconds to generate a thumbnail for each photo in a network folder. Usually, only 10% of thumbnails actually display; the rest are default jpg icons. A thumbs.db file already exists inside this folder, so presumably the thumbnails have been generated before. Why do they have to be generated again? The PC is Win7 64-bit. The server is Windows 2003 Server SP2.

  • apache high system CPU time

    - by jperelli
    I have a web server: ubuntu apache+php app+postgresql and a stats server: ubuntu apache+php - piwik and munin2 installed. The communication for munin2 is made through ssh. In munin i see a lot of system cpu activity, that I assume it it because of apache (i see 5 or 6 apache instances using ~5% CPU on top) I was not having this system CPU activity before. Does anyone knows how can I see where that comes from? EDIT: some munin graphs

  • Printer stops printing at page 138, every time.

    - by ghostz00
    I'm printing invoices from quickbooks premier 2009 and I have around 300 to print. But the job always fails at 138. It doesn't give any error messages, the print dialog box just disappears. and quickbooks acts like nothing was printed. The printer is a lexmark color laser c544n on windows xp sp3. It's pretty new. I've tried reinstalling the driver as well as change the way it spools (sending it directly to the printer). But nothing seems to work.

  • Installation fails after period of time

    - by Jack Marchetti
    I'm running Windows 7 64 bit, Ultimate. I'm running into a problem where, if my computer is on long enough, I am unable to install any software. For example, if I reboot and try to install something, for the most part, it will succeed. if I try and install something after a few hours/days, it will always fail. Sometimes stating that "a previous install failed..." or "an install is already taking place..." even though there is nothing being installed. This also seems to be making my Windows updates fail at a pretty regular rate. Any ideas?

  • Real time audio streaming

    - by Josh K
    I have a remote computer running OS X. I would like to stream the audio from the microphone input over the network so I can listen to it. Primarily I want to do this because I'm out of the office but still need to communicate with people there. I would like to use VLC, but am not fully aware of the options available. I tried SoundFly (as recommended by another answer) but this didn't seem to want to connect. At this point I should note that I'm using a VPN network to connect to the remote computer (using Hamachi). I can open up ports / etc fine though, so I should be able to do this. Alright, I found Nicecase which does exactly what I want but I would prefer to not have to shell out $40 for it.

    Hi guys, something that annoys me, the address bar on Safari keeps on disappearing when I quit and re-open Safari, on default. In fact, when I open a new tab it does the same. Not sure why it does it, i have tried customising toolbar and adding address bar there again.

  • How to measure Silverlight control load time with Google Analytics

    - by ddehghan
    Hi everyone I have a simple silverlight page for for finding available domain names. I use Google Analytics for monitoring the traffic. I would really like to find out how long it take for users to download and render the Silverlight control.

Key points I would like to measure are: Time it takes to download the silverlight control Time it takes to initialize the control Thanks

  • Full computer freeze with audio stuttering after playing games for a period of time

    - by Wes
    I've been having a problem with my computer freezing completely when playing games like LA Noire or SW:TOR (yay early access!). Basically, what happens is I will play for around an hour or so (depending on the game) and when the freeze happens, the entire computer locks up and any audio that was being played glitches out and stutters broken-record style (only much shorter. Very techno). I think it might be heat related and thought it might be my video card overheating, so I have been setting my video card (Nvidia Geforce 260GTX 216-core) fan to highest setting, but that has little to no effect. Now I'm beginning to think it's either my FSB or CPU overheating. Can anyone provide some insight or similar experiences? I'm really at a loss and don't wanna damage my rig beyond repair.
