• List of Application indicators

  - by user8592

  I installed Ubuntu 11.04 on one of my systems and I am using Unity interface. Unity is working quite nice so far but i really miss panel applets for net speed, cpu temp, and system monitor. These applets show useful quickinfo. Unlike 10.10, there is no other way to get these infos onto the panel or unity launcher. There are solutions like screenlets and conky but they don't feel appropriate for a clean desktop look. If you know then please list out any third party indicators with links so that they can be found at one place.

• Loading large amounts of data to an Oracle SQL Database

  - by James

  Hey all, I was wondering if anyone had any experience with what I am about to embark on. I have several csv files which are all around a GB or so in size and I need to load them into a an oracle database. While most of my work after loading will be read-only I will need to load updates from time to time. Basically I just need a good tool for loading several rows of data at a time up to my db. Here is what I have found so far: I could use SQL Loader t do a lot of the work I could use Bulk-Insert commands Some sort of batch insert. Using prepared statement somehow might be a good idea. I guess I was wondering what everyone thinks is the fastest way to get this insert done. Any tips?

• How to map it? HasOne x References

  - by Felipe

  Hi everyones, I need to make a mapping One by One, and I have some doubts. I have this classes: public class DocumentType { public virtual int Id { get; set; } /* othes properties for documenttype */ public virtual DocumentConfiguration Configuration { get; set; } public DocumentType () { } } public class DocumentConfiguration { public virtual int Id { get; set; } /* some other properties for configuration */ public virtual DocumentType Type { get; set; } public DocumentConfiguration () { } } A DocumentType object has only one DocumentConfiguration, but it is not a inherits, it's only one by one and unique, to separate properties. How should be my mappings in this case ? Should I use References or HasOne ? Someone could give an example ? When I load a DocumentType object I'd like to auto load the property Configuration (in documentType). Thanks a lot guys! Cheers

• AJAX form sections - how to pass url of next stage of form

  - by dan727

  Hi, I've got a multi-part form (in a PHP MVC setup) which I have working correctly without javascript enhancement. I'm starting to add the AJAX form handling code which will handle each stage of a form submission, validating/saving data etc, before using AJAX to load the next stage of the form. I'm wondering how best to pass the URL of the next stage to the current form being processed, so that my jQuery form handling code can process the current form, then load the next part via AJAX. The form "action" is different from what the url of the next stage of the form is - what do you think would be good practice here? I was thinking about either appending the url of the next stage to the form action url, via a query string - then just use javascript to extract this url when the form is successfully processed. The other option is via a hidden form element. Not sure what other client side options I have here Any thoughts?

• How do to check to see if the user has a Google account.

  - by skrat

  Is there any safe way to detect, on a web page, client side (JS), whether user has an Google/Yahoo/Live/? account? I know about some suspicious ways to do this by styling visited links and then sneaking on computed style attribute, but it's more of a hack, Mozilla and maybe other are planning to crack down on this, as it might be abused. But I need this to allow users more integration with their identity providers, like: Have a Google account? ~ load contacts for sharing from Google Contacts API Have an Yahoo account? ~ load contacts for sharing from Yahoo Contacts API none of the above? show no link I don't want to provide all these options to all visitors, would be nice if I can detect the account, and provide integration only in that case.

• Google Maps: Multimarker not working

  - by HyperDevil

  Hi, I want to plot several markers on my map. Found some code on the internet, for that user it worked. The array is generated by PHP, example: var ships = [['61','10.2']['60.5','10.1']]; My Javascript: var map; function load(ships) { initialize(); createShips(ships); } function initialize() { //build the map var myLatlng = new google.maps.LatLng(63.65,10.65); var myOptions = { zoom: 9, center: myLatlng, mapTypeId: google.maps.MapTypeId.TERRAIN } var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); } function createShips(ships) { for (var i = 0; i < ships.length; i++) { new google.maps.Marker({ position: new google.maps.LatLng(ships[i][0], ships[i][1]), map: map, title: ships[i][0] }); } } My html function to start the map is: body onload="load()" The map seems to appear, but no markers :(

• jQuery: how to find first visible input/select/textarea excluding buttons?

  - by Artem

  I tried $(":input:not(input[type=button],input[type=submit],button):visible:first") but it doesn't find anything. What is my mistake? UPD: I execute this on $(document).load() <script type="text/javascript"> $(window).load(function () { var aspForm = $("form#aspnetForm"); var firstInput = $(":input:not(input[type=button],input[type=submit],button):visible:first", aspForm); firstInput.focus(); }); </script> and in the debug I can see that firstInput is empty. UPD2: I'm in ASP.NET page running under Sharepoint. I've found so far that for some elements it does find them (for fixed ones) and for some don't. :(

• Do you leave Windows Automatic Updates enabled on your production IIS server?

  - by Nobody

  If you were running a 24/7 website on Windows Server 2003 (IIS6). Would you leave the Windows automatic update feature enabled or would you turn it off? When enabled, you always get the latest security patches and bug fixes automatically as soon as they're available, which is the most secure choice. However, the machine will sometimes get automatically rebooted to apply the updates leading to a couple of minutes of downtime in the middle of the night. Also, I've seen rare occasions where the machine does not restart correctly resulting in further downtime. If auto updates are off, when do you apply the patches? I guess you have to use a load balancer with multiple web servers and rotate them out of the production site, apply patches manually, and put them back in. This can be logistically inconvenient when the load balancer is managed by a hosting company. You will also have machines in production that don't always have the latest security patches and you have to routinely spend time deciding which patches to apply and when.

• Wrong download of Ubuntu 13.10 desktop: AMD instead of wanted Intel [duplicate]

  - by L. Williams

  This question already has an answer here: Difference between the i386 download and the amd64? 5 answers My PCs are Intel CPUs e.g. Core2 Quad, 64 bit, no AMD in network, but from ubuntu.com/download site, selecting 13.10 Desktop for 64 bit, it repeatedly only offers *AMD.ISO version, which of course fails to install on my Intel (or Atom) based PCs. Wuzzup, and what URL has a download for the Intel CPU systems? Rem: this is for Saucy 13.10 Desktop 64 OS ISO. TIA.

• Objective C: App freezes when using a timer

  - by Chris

  It took me hours to figure out how to implement a timer into my program, but when it runs, the app doesn't load completely as it did before the timer. In my main.m: int main (int argc, const char * argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; OutLauncher *theLauncher = [[OutLauncher alloc] init]; NSTimer *theTimer = [theLauncher getTimer]; [theTimer retain]; [[NSRunLoop currentRunLoop] addTimer: theTimer forMode: NSDefaultRunLoopMode]; [[NSRunLoop currentRunLoop] run]; [pool release]; return 0; } The file OutLauncher is being imported into that, which looks like this: - (void)doStuff { NSLog( @"Doing Stuff"); } - (NSTimer *)getTimer{ NSTimer *theTimer; theTimer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector: @selector(doStuff) userInfo:nil repeats:YES]; return [theTimer autorelease]; } The timer works, the console updates every second with the phrase "doing stuff" but the rest of the program just won't load. It will if I comment out the code I added to int main though

• Controlling when SQL UPDATE is executing on ehcache 'd classes

  - by thomers

  We are using Hibernate and ehcache as 2nd level cache. If I load an entity that is cached (e.g. cache-usage="read-write") and update it, it seems that this immediately results in an SQL UPDATE. (How) Can I influence when this SQL UPDATE happens? hibSession = HibernateUtil.getReadWriteSession(); tx = hibSession.beginTransaction(); User u = (User) hibSession.load(User.class, user_id); u.modify(); hibSession.update(u); tx.commit(); Edit: It seems that setting a CacheMode should have an effect, but each hibSession.update() results in an immediate SQL UPDATE, regardless which CacheMode I set.

• Deactivate any calls to Log before publishing: are there tools to do this?

  - by Nicolas Raoul

  According to Google, I must "Deactivate any calls to Log methods in the source code" before publishing my Android app (section 4 of the publication checklist). My open-source project is large and it is a pain to do it manually every time I release. Additionally, removing a Log line is potentially tricky, for instance: if(condition) Log.d(LOG_TAG, "Something"); data.load(); data.show(); If I comment the Log line, then the condition applies to the next line, and chances are load() is not called. Are such situations rare enough that I can decide it should exist? This is on the official checklist, so I guess many people do this on a regular basis. So, is there a tool that removes all Log lines? Preferably one that is not tricked by code like the above.

• Kernel Panic while Installing Ubuntu 12.10 from USB Drive

  - by user100889

  Good evening, I recently looked into installing Ubuntu alongside my Windows. I was able to mount the iso on a USB drive using Universal USB Installer. I verified it with the MD5sum utility and the hash is correct. When installing, I can get to the screen where I choose the boot order, select the USB drive, and then I get to a screen where Ubuntu seems to be 'loading' (purple background with Ubuntu logo and name in the middle). Then, all of a sudden, I get a "Kernel Panic - Not syncing: fatal exception in interrupt" error message. My specs : Intel Core 2 Duo CPU T5850 @ 2.16 GHz / 4 GB of ram / Packard Bell computer from 2007. / Windows 7 Ultimate x64 installed. What should I do now ? Thanks for your help.

• How to enforce lazy loading of entities on certain conditions

  - by Samuel

  We have an JPA @Entity class (say User) which has a @ManyToOne reference (say Address) loaded using the EAGER option which in turn loads it's own @ManyToOne fields (say Country) in a EAGER fashion. We use the EntityQuery interface to count the list of User's based on a search criteria, during such a load all the @ManyToOne fields which have been marked as EAGER get loaded. But in order to perform a EntityQuery.resultCount(), I actually don't need to load the @ManyToOne fields. Is there a way to prevent loading of the EAGER fields in such cases so that we can avoid the unnecessary joins?

• Session Timeout and page response time

  - by Johnny5

  Hi, I'm load testing an asp.net app. The load test is simulating 500 user doing searchs on the site and browsing the results. I'm observing that the more I reduce the session timeout limit (in web.config) the better the page response time. For exemple, with a timeout at 10 minutes, I got an average response time of 8.35 seconds. With a timout at 3 minutes, the average response time for the same page is 3,98 seconds. The session in stored "InProc". I supposed the memory used by the "no more used but still actives" sessions may be in cause. But, even if there is more memory used when the timeout is at 10, there is still plenty of memory available (about 2.7Gb). Any ideas?

• Data persistance with BufferedReader and PrintWriter?

  - by Nazgulled

  I have this simple application with a couple of classes which are all related. There's one, the main one, for which there is only one instance of. I need to save save and load that using a text stream. My instructor requirement is BufferedReader to load the stream and PrintWriter to save it. But is this even possible? To persist a data object/class with a text stream? I know how to do it with and object, using serialization. But I don't see how am I supposed to do it using text streams. Suggestions?

• using key/value collection in session

  - by jumpdart

  Question: What is a good datatype to keep in session for a large collection of keys and values to frequently reference and update? Application: Updating an old .NET web app with a million pages and grids to have all the grids maintain their sort. They currently access helper code to format themselves graphically on load and on sort. I figured I could add to that code to check for a key based on the page and grid id in a collection in session to see if it has a previous expression on load. and the on sort update/add its appropriate item in the collection. Thoughts? Dictionary vs NameValueCollection

• What sort of things can cause a whole system to appear to hang for 100s-1000s of milliseconds?

  - by Ogapo

  I am working on a Windows game and while rendering, some computers will experience intermittent pauses ("hitches" for lack of a better term). When profiled they appear in seemingly random places in the code. Eventually I noticed that it wasn't just my process that was affected, but (seemingly) every process on the system. All of the threads in my application hitch at once. The CPU utilization drops during these hitches and it appears as if most processes make no progress. This leads me to believe this may be an Operating System or Driver issue, but it only occurs while playing the game (and only on some systems). What sort of operations might the operating system be doing that would require the kernel to pause all user threads and block. Some kind of I/O? At first I thought of paging but my impression is that would only affect a single process, no? Some systems in use: Windows, DirectX (3d), nVidia cards (unknown if replicates on ATI), using overlapped io for streaming

• Return segmented average from SQL Query?

  - by Guillaume Filion

  Hi, I measure the load on DNS servers every minute and store that into an SQL DB. I want to draw a chart of the load for the last 48 hours. That's 69120 (48*24*60) data points but my chart's only 800 pixels wide so to make things faster I would like my SQL query to return only ~800 data points. It's seems to me like a pretty standard thing to do, but I've been searching the web and in books for such a thing for a while now and the closest I was able to find was a rolling average. What I'm looking for a more of a "segmented average": divide the 69120 data points in ~800 segments, then average each segment. My SQL table is: CREATE TABLE measurements ( ip int, measurement_time int, queries int, query_time float ) My query looks like this SELECT ip, queries FROM measurements WHERE measurement_time>(time()-172800) Thanks a lot!

• Problem with the screen resolution on Ubuntu 12.04

  I just installed ubuntu on my laptop. The screen resolution is stuck in 1024x768. The screen is made for 1280x800. When I run xrandr I get: xrandr: Failed to get size of gamma for output default Screen 0: minimum 800 x 600, current 1024 x 768, maximum 1024 x 768 default connected 1024x768+0+0 0mm x 0mm 1024x768 61.0* 800x600 61.0 1280x800 isn't offered and I get gamma size error. I was going to look into the Xorg.conf file but I couldn't locate it. 1280x800 was displayed in Windows 7 and I think it is being displayed in Grub before ubuntu starts also.
