Oracle has its own date format – DD-MM-YY (24-sep-09). So, to insert a value into Oracle date field you should somehow convert date from your format. Sure it can be done using some date/time module or your own function. But there are two simpler ways – set desire date/time format for session or use Oracle date conversion function. To set specific date/time format for the […]
Connect to Oracle DB from Perl script
After successful installation of DBD::Oracle it’s time to use it. The connection string is the same as for he rest DB: my $dbi = DBI->connect(“dbi:Oracle:$db_name:$db_host:$db_port”, $db_user, $db_pass); As result of running code above I got following error: Couldn’t connect to database db_name: ORA-12154: TNS:could not resolve the connect identifier specified (DBD ERROR: OCIServerAttach) After googling I found that the problem was that. I tried to […]
Installing DBD::Oracle under Fedora 11
Recently I got a task which needs to communicate with database Oracle from Perl. Perl has an excellent database abstraction interface DBI. But for specific database it needs a driver – DBD module. To install DBD::Oracle you have to perform following simple steps: Download and install oracle-instantclient11.2-basic and oracle-instantclient11.2-devel RPMs from Instant Client Downloads for Linux x86 page. Export ORACLE_HOME: export ORACLE_HOME=/usr/lib/oracle/11.2/client/ Install DBD::Oracle using […]

VMWare and kernel 2.6.24.X
Last week I upgrade my Fedora Core 8 to the latest stable kernel 2.6.24.3-12. As result the compilation of VMWare module vmmon gave that error: /tmp/vmware-config1/vmmon-only/./include/compat_wait.h:60: error: conflicting types for ‘poll_initwait’ include/linux/poll.h:65: error: previous declaration of ‘poll_initwait’ was here /tmp/vmware-config1/vmmon-only/linux/driver.c:172: warning: initialization from incompatible pointer type /tmp/vmware-config1/vmmon-only/linux/driver.c:176: warning: initialization from incompatible pointer type make[2]: *** [/tmp/vmware-config1/vmmon-only/linux/driver.o] Error 1 make[1]: *** [_module_/tmp/vmware-config1/vmmon-only] Error 2 make[1]: Leaving […]
Skype for Linux with video support
Recently I installed the latest Skype for Linux (2.0.0.43) on my both systems: Fedora 8 and Kubuntu 7.04. I was surprised because the video calls really work. We talked with one of my friends about 40 minutes (he uses Windows). The quality of sound and picture is good (we both have DSL Internet connection). Not sure how it’ll be for dial-up. Currently I cannot test […]
Shuttle $199 Linux PC
Shuttle has announced a budget PC in compact form-factor with funny skins. Just for $199 you will get “an Intel Celeron processor, a 945GC chipset, 512MB of memory and either a 60GB or 80GB hard drive. What it won’t have: an optical drive or a PCI Express slot. Despite that, it’s a pretty good-looking box, and comes in red, blue, white, and black, each with […]
Accessing the Nokia N800 camera
Linux-based Internet Tablet Nokia N800 is very popular. Even coming N810 is not going to replace it completely (I’m not talking about windows-based Origami). Using Maemo SDK it’s fairly simple develop new applications or porting existing ones. For sure to be success you need a right documentation. Following article from IBM.com explains obviously how to use N800 camera API. P. S. The easiest way IMHO […]
