• I'm tired of JButtons, how can I make a nicer GUI in java ?

  - by Jules Olléon

  So far I've only build "small" graphical applications, using swing and JComponents as I learned at school. Yet I can't bear ugly JButtons anymore. I've tried to play with the different JButton methods, like changing colors, putting icons etc. but I'm still not satisfied. How do you make a nicer GUI in java ? I'm looking for not-too-heavy alternatives (like, without big frameworks or too complicated libraries).

• Relaying to tech "support" that computer is actually broken.

  - by Sion

  First some background: I have a Dell Inspiron 15R M050, it is still under the Dell limited warranty and the Best Buy Extended warranty. I am currently dual booting Debian Squeeze and Windows 7, the only reason I go into Windows is to play video games specifically steam games. Issue: When I play my games in Windows I am capable of playing for anywhere from 5 minutes to 2 hours before I suffer a hard-lock. I cannot alt-tab, ctrl-alt-delete, ctrl-shift-escape do anything for 2-3 minutes. After this hard-lock period everything runs fine, I can continue the game for probably another hour at least before I suffer another lock. Games: Borderlands, Splinter Cell: Chaos Theory, Starcraft 2, Garrys Mod What I have tried: Running the diagnostic suite in the dell bios, restoring the OEM Windows recovery partition on the HD, fresh installing Windows 7 Professional, updating BIOS, Calling tech support and having them run a software Hardware Diagnostics suite. The question: I think from the research that I have performed that it might be a lack of thermal paste on the CPU, would I be able to go to Best Buy and have them do a hardware diagnostic from the hardware level then have them be able to tell Dell that there is a hardware issue? Or would there be a different problem?

• How do I prevent my ASP .NET site from continually prompting for user credentials?

  - by gilles27

  I'm trying to get an ASP .NET website up and running on IIS6. The site will run in its own application pool, and uses Windows authentication, with anonymous access turned off. When I run the app pool under NETWORK SERVICE, everything works fine. However we need the app pool to run under a different account, because this account needs some extra privileges (we are printing Word documents). This new account is a member of the local users group, and the IIS_WPG group. It has also been granted the "Log on as a service right". When I browse to the site I am prompted for credentials, not once, but several times. When the page finally loads it looks wrong because the style sheets have not been applied. My suspicion is that I am being prompted once for each file (e.g. all the images, styles and script files) the browser requests, and that for some reason the website is unable to validate those credentials in order to serve the files back. If I allow anonymous access the page loads fine - we don't want to allow it but I mention it in case it offers any further clues. My theory is that perhaps the account the app pool runs under needs permissions to validate domain credentials? If that is so, how do I enable this?

Is there any best-practice for such kind of things. I'm currently use chunking channel.

• Several ifstream vs. ifstream + constant seeking

  - by SpyBot

  I'm writing an external merge sort. It works like that: read k chunks from big file, sort them in memory, perform k-way merge, done. So I need to sequentially read from different portions of the file during the k-way merge phase. What's the best way to do that: several ifstreams or one ifstream and seeking? Also, is there a library for easy async IO?

• Links break in IE9 when using Wordpress plugins in non Wordpress Page

  - by mouli

  I have a site that uses SEF URLs and htaccess RewriteRules to serve up the pages. This has worked fine for several years until the arrival of IE9. Now it appears that the links are not being rewritten and the site is dead in the water. I have tried different compatabilty modes, to no avail, and I've played with the Rewrite Rules over and over, tried different doctypes and a few other browser settings. I agree that it cannot in theory be a browser specific problem if the problem is with the htaccess file but this site works in IE8, firefox and chrome. I have run the rewriterule through a validator and it looks fine. Any ideas would be appreciated as I am running out of ideas. The site is www.marlboroughsounds.co.nz a sample link is http://www.marlboroughsounds.co.nz/walking/freedom-walk-queen-charlotte-track/4dfw and the rewrite rule thats not working looks like this: RewriteRule ^walking/.*/([a-z0-9_]*)/?$ /walking.php?act_code=$1 [L] The link fails and it serves up a browser 404 page, not even the custom 404 I have for the site. Any ideas would be much appreciated as I am stumped.

• Efective way to avoid integer overflow when multiplying?

  - by Jonathan

  Hi, I'm working on a hash function which gets a string as input. Right now I'm doing a loop and inside the hash (an int variable) is being multiplied by a value and then the ASCII code for the current character is added to the mix. hash = hash * seed + string[i] But sometimes, if the string is big enough there is an integer overflow there, what can I do to avoid it while maintaining the same hash structure? Maybe a bit operation included inside the loop?

• CentOS 6.3 Virtual under OpenVZ cannot ping, host lookups, outbound connections while postfix running

  - by Paul Cravey

  My best theory is that some kernel limit is being hit preventing outbound connections. We have tried basically everything from tcpdumps to provisioning an entirely new virtual server (we do not have this problem on any other virtuals), however the problem somehow carried over, even with new postfix build (working). Emails work, and outbound connections work, so long as postfix does not have too much going on. /proc/user_beancounters shows no limits being hit (show below). Nevertheless, pings fail even to IP addresses. TCP stack appears healthy. Load is low. No iowait. Flushed iptables already. Has anyone experienced anything like this? uid resource held maxheld barrier limit failcnt 3: kmemsize 166216365 170262528 9223372036854775807 9223372036854775807 0 lockedpages 0 0 9223372036854775807 9223372036854775807 0 privvmpages 285727 351885 9223372036854775807 9223372036854775807 0 shmpages 16933 17605 9223372036854775807 9223372036854775807 0 dummy 0 0 0 0 0 numproc 150 303 9223372036854775807 9223372036854775807 0 physpages 314156 326191 0 1280000 0 vmguarpages 0 0 9223372036854775807 9223372036854775807 0 oomguarpages 165355 165355 9223372036854775807 9223372036854775807 0 numtcpsock 89 172 9223372036854775807 9223372036854775807 0 numflock 22 76 9223372036854775807 9223372036854775807 0 numpty 1 2 9223372036854775807 9223372036854775807 0 numsiginfo 0 75 9223372036854775807 9223372036854775807 0 tcpsndbuf 2733472 4371752 9223372036854775807 9223372036854775807 0 tcprcvbuf 1798336 5427296 9223372036854775807 9223372036854775807 0 othersockbuf 491120 1000760 9223372036854775807 9223372036854775807 0 dgramrcvbuf 0 238728 9223372036854775807 9223372036854775807 0 numothersock 361 505 9223372036854775807 9223372036854775807 0 dcachesize 135941831 136114679 9223372036854775807 9223372036854775807 0 numfile 2905 4990 9223372036854775807 9223372036854775807 0 dummy 0 0 0 0 0 dummy 0 0 0 0 0 dummy 0 0 0 0 0 numiptent 8 9 9223372036854775807 9223372036854775807 0 [root@bni /]# ping 4.2.2.1 PING 4.2.2.1 (4.2.2.1) 56(84) bytes of data. --- 4.2.2.1 ping statistics --- 9 packets transmitted, 0 received, 100% packet loss, time 8493ms [root@bni /]# service postfix stop [root@bni /]# ping 4.2.2.1 PING 4.2.2.1 (4.2.2.1) 56(84) bytes of data. 64 bytes from 4.2.2.1: icmp_seq=1 ttl=53 time=8.63 ms 64 bytes from 4.2.2.1: icmp_seq=2 ttl=53 time=8.62 ms 64 bytes from 4.2.2.1: icmp_seq=3 ttl=53 time=8.63 ms 64 bytes from 4.2.2.1: icmp_seq=4 ttl=53 time=8.66 ms Outbound connections of all sorts fail when postfix is running.

  I am trying to create an iPhone app for a large website (as big as amazon.com) and it involves using cookies and what not to get authenticated via the Apache intercepter and access the web services exposed by the main website. For that I am looking for strategies to go about developing it. I am new to iPhone development and I am mostly looking for some architectural guidance. Does anyone know how services like eBay and Amazon work seamlessly across the website and iPhone app?

• WPF windows locked when calling webservice. Even when run asynchronously

  - by SumGuy

  Hi there. I'm having a big problem when calling a web service from my WPF application. The application/window locks until the process has completed. I've attempted to run this asynchronously but the problem still persists. Currently, the web service call I'm making can last 45-60 seconds. It runs a process on the server to fetch a big chunk of data. As it take a little while I wanted to have a progress bar moving indeterminately for the user to see that the application hasn't stalled or anything (you know how impatatient they get). So: private void btnSelect_Click(object sender, RoutedEventArgs e) { wDrawingList = new WindowDrawingList(systemManager); AsyncMethodHandler caller = default(AsyncMethodHandler); caller = new AsyncMethodHandler(setupDrawingList); // open new thread with callback method caller.BeginInvoke((Guid)((Button)sender).Tag, MyAsyncCallback, null); } Click a button and the app will create the form that the async stuff will be posted to and set up the async stuff calling the async method. public bool setupDrawingList(Guid ID) { if (systemManager.set(ID)) { wDrawingList.Dispatcher.Invoke(DispatcherPriority.Background, new Action(() => { wDrawingList.ShowForm(); Hide(); })); return true; } return false; } This is the async method. The showForm method contains the calls to setup the new form including the monster web service call public void MyAsyncCallback(IAsyncResult ar) { // Because you passed your original delegate in the asyncState parameter of the Begin call, you can get it back here to complete the call. MethodDelegate dlgt = (MethodDelegate)ar.AsyncState; // Complete the call. bool output = dlgt.EndInvoke(ar); try { // Retrieve the delegate. AsyncResult result = (AsyncResult)ar; AsyncMethodHandler caller = (AsyncMethodHandler)result.AsyncDelegate; // Because this method is running from secondary thread it can never access ui objects because they are created // on the primary thread. // Call EndInvoke to retrieve the results. bool returnValue = caller.EndInvoke(ar); // Still on secondary thread, must update ui on primary thread UpdateUI(returnValue == true ? "Success" : "Failed"); } catch (Exception ex) { string exMessage = null; exMessage = "Error: " + ex.Message; UpdateUI(exMessage); } } public void UpdateUI(string outputValue) { // Get back to primary thread to update ui UpdateUIHandler uiHandler = new UpdateUIHandler(UpdateUIIndicators); string results = outputValue; // Run new thread off Dispatched (primary thread) this.Dispatcher.Invoke(System.Windows.Threading.DispatcherPriority.Normal, uiHandler, results); } public void UpdateUIIndicators(string outputValue) { // update user interface controls from primary UI thread sbi3.Content = "Processing Completed."; } Any help or theories are appreciated. I'm at a loss. Thanks in advance
