Logic Exception

Last week, after I upgraded to the Netbeans 7.0 Beta, scanning issues, coupled with spontaneous freezes, cropped up again. I initially thought I was running into the same heap size issue as described in one of my earlier posts. After some research, it turns out the issue was related to garbage collection this time. http://performance.netbeans.org/howto/jvmswitches/index.html http://wiki.netbeans.org/FaqScanningAndIndexingPerformanceHints#Use_different_Garbage_Collector_strategy We've had several reports from users that choosing 'Concurrent Mark And Sweep' garbage collector improves scanning performance. This may or may not make a difference on your system. The problem is that people use different hardware, different versions of JDK and they have different default GC algorithm chosen by their JVM. I added the required flags to my netbeans.conf file and performance improved to a point where it is now much better than it was previously. netbeans_default_options="...

Yes, it is possible. The device is compatible and can connect to the local 3G network (Turkcell) with minimal hassle. In addition, even though I had to purchase a two-year T-mobile subscription with my phone, the device is unlocked! Disclaimer: I purchased this phone directly from Google in May 2010. Google is no longer doing this. As soon as I landed in Istanbul, I went to the Turkcell kiosk, registered my IMEI number, purchased a prepaid card, and activated it. You MUST register your phone with the government agency or it may be banned permanently. The next step is to subscribe to the 3G internet service. There are two types of 3G services: 1. Faturali (invoiced) 3G Internet http://www.turkcell.com.tr/bireysel/3G/3Ginternet/tarifeler/faturali3Ginternet Subscription for this plan is automatically renewed every month. And there is an overuse charge which is currently 0,050 TL/MB. 2. Faturasiz (non-invoiced) 3G Internet http://www.turkcell.com.tr/bireysel/3G/3Ginternet/t...

If you wish to shorten your Symfony 1.4 URLs (http://www.yourdomain.com/symfonyApp.php/user/login) by removing the php extension from the controller (http://www.yourdomain.com/symfonyApp/user/login), then read on. 1. Update your factories.yml file and add the relative_url_root option as described below: all: request: class: sfWebRequest param: logging: %SF_LOGGING_ENABLED% path_info_array: SERVER path_info_key: PATH_INFO relative_url_root: "" formats: txt: text/plain js: [application/javascript, application/x-javascript, text/javascript] css: text/css json: [application/json, application/x-json] xml: [text/xml, application/xml, application/x-xml] rdf: application/rdf+xml atom: application/atom+xml 2. Create a symbolic link in your web directory to your controller: cd /your/symfony/project/dir/web ln -s symfonyApp.php symfonyApp 3. Update your apache c...

I was having problems with Netbeans 6.9 where it would just hang trying to scan my codebase which consists of around ~200.000 PHP files. Another issue was related to code completion and suggestions which caused the IDE to become unresponsive or, in some cases, hang. It looks like the issue is related to the heap size which is automatically set since version 6.0. Since NetBeans version 6.0, the default limit for heap size (-J-Xmx) is determined automatically, with respect to the amount of memory available on the system. There is no -J-Xmx option specified in netbeans.conf. However, if you specify the heap size limit (i.e. you add the -J-Xmx... option to netbeans.conf), then the limit given by you will be respected. http://wiki.netbeans.org/FaqSettingHeapSize So I ended up increasing the heap size in netbeans.conf by adding the "-J-Xmx2048m" option. Here are my current settings: netbeans_default_options="-J-client -J-Xss2m -J-Xms32m -J-Xmx2048m -J-XX:PermSize=32m...

Finally decided to port all my work in my subversion repostiry to Git... A couple of tips that may be helpful for new starters: 1. In order to do an svn export, simply execute: git archive | tar -x -C /path/to/dir 2. To revert local edits, run: git checkout filename 3. The concept of remotes was confusing at the beginning. Think of them as shortcuts to remote repositories. So instead of typing complex URL's, all you need to do is git push remote branch git pull remote branch once a remote is added. 3. Enjoy your merges :)

SSL/TLS vs STARTTLS This seemed to be confusing at first but here is what it boils down to: With STARTTLS, an existing TCP connection is upgraded to an encrypted one after the SMTP handshake. On the other hand, with SSL/TLS, an ecnrypted connection is negiotiated right away before an SMTP handshake takes place. In other words, STARTTLS is "TLS inside SMTP", while SSL/TLS is "SMTP inside TLS". See this page for more information. Another important difference between these two schemes is that STARTTLS does not require a separate port. You can continue to use the same smtp (25) or imap (143) port. SSL/TLS on the other hand requires separate smtp (465) and imap (993) ports. Setup I wanted to implement a STARTTLS scheme; however, I decided to revert back to SSL/TLS due to: 1. I am running Dovecot dovecot-1.0.7 on CentOS release 5.5. Unfortunately for me, I was not able to require SSL connections since the "ssl = required" configuration option is not av...

Setting up pnp4nagios on Fedora is pretty straightforward. 1. Install pnp4 nagios yum install pnp4nagios 2. Setup /etc/nagios/nagios.cfg process_performance_data=1 host_perfdata_command=process-host-perfdata service_perfdata_command=process-service-perfdata 3. Setup /etc/nagios/objects/commands.cfg to send performance data to pnp4nagios. define command{ command_name process-host-perfdata command_line /usr/bin/perl /usr/libexec/pnp4nagios/process_perfdata.pl -d HOSTPERFDATA } define command{ command_name process-service-perfdata command_line /usr/bin/perl /usr/libexec/pnp4nagios/process_perfdata.pl } 4.

First of all, you need Postgres version 8.2 or newer since mogdbsetup refuses to run with older versions. Anyways, I spent a quite a bit of time trying to install MogileFS with Postgres. I was getting "Can't create temporary test database:" errors. The answer was in the ~/.cpan/build/mogilefs-server-2.34/blib/lib/MogileFS/Test.pm file. The temp_store subroutine was defaulting to MySQL... Here is the setup step by step on my Fedora 12: yum install mogilefsd yum install mogstored yum install perl-CPAN // if needed yum install perl-MogileFS-Client perl-MogileFS-Utils yum install perl-DBD-Pg yum install perl-IO-AIO Setup services. chkconfig --levels 345 mogilefsd on chkconfig --levels 345 mogstored on Setup a test database to be used during compilation. $ createuser -SRlD mogile $ createdb -E UTF8 -O mogile tmp_mogiletest Setup environment variables for testing $ MOGTEST_DBUSER=mogile $ MOGTEST_DBHOST=dbhost $ MOGTEST_DBNAME=tmp_mogiletest $ MOG...

Could not start the httpd service for a while due to: Syntax error on line 196 of /etc/httpd/conf/httpd.conf: Cannot load /etc/httpd/modules/mod_file_cache.so into server: /etc/httpd/modules/mod_file_cache.so: cannot open shared object file: No such file or directory I had to manually comment out two unneeded modules from the /etc/httpd/conf/httpd.conf: #LoadModule file_cache_module modules/mod_file_cache.so #LoadModule mem_cache_module modules/mod_mem_cache.so More here .

Today, while I was trying to set up Nagios on my local box at work when Nagios refused to start due to bad configuration error. Starting nagios:CONFIG ERROR! Start aborted. Check your Nagios configuration. It took some to time to realize that a "check_command" line has to be defined even for passive check. define service { use local-service service_description passive_service check_command check_dummy!2 active_checks_enabled 0 passive_checks_enabled 1 } The best explanation is from the 2.0 docs located at: http://nagios.sourceforge.net/docs/2_0/freshness.html What Happens When A Service Check Result Becomes "Stale" If the check results of a service are found to be "stale" (as described above), Nagios will force an active check of the service by executing the command specified by the check_command option in the service definition. It is important to note that an active ...

Ok, here goes my first blog post ever... Last Friday, I decided to upgrade from Fedora 10 to 12 using the PreUpgrade tool. The download and the installation process went well until the time came to boot into the new system. I suspected something was wrong when I realized the fc12 kernel line was missing from the Grub menu, and I was "relieved" to see I was right the whole time when I was presented with: Give root password for maintenance (or type Control-D to continue): I could not even type. Every time I hit a key, i was prompted with the same line... Thankfully, I had that old custom compiled vanilla kernel sitting in the Grub menu that allowed me to boot and utilize the command line at least. Although I was able to interact with Grub during the boot process, I decided to complicate the problem for no apparent reason and thought there must be something wrong with the grub itself... I burned the Fedora 12 DVD iso image and booted the computer into rescue mode... Two c...
