  • '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.

  • 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.

  • 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

I know this is the time since the Equinox, I am just not sure how to convert this to a MYSQL format.

  • 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

  • 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

  • Detaching EBS Volumes (in LVM) take a lot of time

    - by Cheezo
    I have an EC2 Instance(EBS Backed-root partition) with EBS volumes configured via LVM. I have formatted it as ext4 and can mount it to store data etc. Now i want take a snapshot of the root partition, hence in that case i go and detach the other non-root EBS volumes (configured in LVM). Here a regular detach does not work, and i have "force" detach almost always. Although, i another similar setup with RAID instead of LVM and there after stopping RAID, i can easily detach. The whole setup is running Ubuntu Maverick 10.10 Please assist me in the same.

  • 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.

  • Incrementing ticket numbers each time I print

    - by Danny
    I have an excel sheet where I have a set 4 identical tickets to print per page which we use for stock takes. Rather then creating a huge document with 1000 pages for 4000 tickets each with their own unique ticket number (starting from 1) I would like to find a Macro or function which will print a page with 4 tickets on (1,2,3,4) then continue to print another with (5,6,7,8) and so on. I have found some code that people have already written but it has only applied to one number changing per page rather than 4 simultaneously and being a complete visual basic novice, I was unable to change the code to suit my preferences. If someone could explain simply how I could achieve this I would be very very grateful :)

  • 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.

  • 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.

  • 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.

  • Login-time quota for VPN users

    - by Isaac
    I have configured Routing and Remote Access Service in Windows Server 2003 as the VPN server. VPN users are defined in Active Directory which is running on this server too. How i can configure the server to give each user a limited download size (for example 1GB) and does not authenticate them when they exceeds their download quota. The VPN server should also disconnect the users that reach their quota. Update: Apparently a third-party RADIUS server could provide this feature. One solution I have found is TekRADIUS but it is commercial. FreeRADIUS is a open-source free RADIUS server but I am not sure if it could these kind of features.

  • 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.

  • 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?

  • 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?

  • upload process times out for different time zones

    - by shilezi
    I have an inhouse(NY) app that cients can upload files to. Usually uploads go pretty quickly for most clients but this particularly cient in the UK always have problems with uploads. not sure if they get any errors but since we log all exceptions, we see this...Error: System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.Net.WebException: The operation has timed out at System.Web.Services.Protocols.WebClientProtocol.GetWebResponse(WebRequest request) at System.Web.Services.Protocols.HttpWebClientProtocol.GetWebResponse(WebRequest request) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) at ... This shouldn't even be an issue because since we noticed they have had this issue before so we bumped up these to maxRequestLength="2097151" executionTimeout="14400". Further investigating this error, i read that it could be a thread timeout since the default is 20minute. A worker process with process id of serving application pool was shutdown due to inactivity. Application Pool timeout configuration was set to 20 minutes. A new worker process will be started when needed. Problem is I am not entirely sure if that really is the case as all other cients mostly North American, have no issues but then their uploads don't seem to go beyond 80mb and the UK client have done a 700mb upload before that i know of. We have tested 750mb before and the whole process took about 15min for upload and processing. Any help on what the real issue here might be? Thanks.
