I was a bit shamed about writing something about windows but then I thought there are so many ugly jobs which are respectable so the job of writing windows programs might fit somewhere too. So this is an article about how to write a small C# application which can calls code from a COM object. As a warning some of the informations here might be considered common knowledge to windows people so please don’t be too judgmental about....
Goal Add a iptables rule for a dynamic changing IP with an associated dyndns host. How to make your computer register your changing IP #apt-get install inadyn Create a /etc/inadyn.conf #cat /etc/inadyn.conf --username ******** --password ******** --update_period 60000 --alias *****.dyndns.org --background Start the process: /usr/sbin/inadyn Make it start at reboot: #crontab -l @reboot /usr/sbin/inadyn First idea Use the hostname directly in iptables. There are 2 problems: the iptables manual says (quote): -s, --source [!...
In new versions of JBoss (such the 4.0.5 which I am using) there is a quartz-ra.sar service which should allow me to define some a job with a cron like specification. Searching the forums and the jboss site I was able to put together quickly an example: import org.jboss.annotation.ejb.ResourceAdapter;import org.jboss.logging.Logger;import org.quartz.Job;import org.quartz.JobExecutionContext;import org.quartz.JobExecutionException; import javax.ejb.MessageDriven;import javax.ejb.ActivationConfigProperty; @MessageDriven(activationConfig = { @ActivationConfigProperty(propertyName = "cronTrigger", propertyValue = "0/2 * * * * ?") }) @ResourceAdapter("quartz-ra....
Getting the correct date and time was always a problem but I could not expect it’s still a problem on today java and OS versions. Trying to deploy a JBoss on various Linux and JBoss I could not notice that on each system the date in the log was different from the localtime. Initially I thought it’s just a JBoss configuration problem but a simple example shows it’s not: import java....
This is a complete example on how to use openssl to fetch a https page. The example is based on the several others I found on the web so my credit is minimal and only consist of modifying just a little the existing examples to compile and work with openssl-0.9.8e on Linux and Solaris. The example #include <openssl/ssl.h> #include <openssl/err.h> #include <openssl/bio.h> #include <iostream> #define MAX_PACKET_SIZE 10000 int main() { BIO * bio; SSL * ssl; SSL_CTX * ctx; /* Initializing OpenSSL */ SSL_load_error_strings(); ERR_load_BIO_strings(); OpenSSL_add_all_algorithms(); SSL_library_init(); //mandatory and missing from some examples ctx = SSL_CTX_new(SSLv23_client_method()); if (ctx == NULL) { std::cout << "Ctx is null" << std::endl; ERR_print_errors_fp(stderr); } //using a store from examples if(!...
How come? As I am currently evaluating a Digital Signage project which makes heavy usage of Flash movies I decided to re-evaluate this technology. Until now I was rather reticent for the following reasons: it is proprietary and does not have any free development tools and (most disturbing) it requires Windows. However today while browsing the Adobe site I found out some rather cool things. There is a product called flex which allows to freely develop flash applications on Linux....
This describes the modifications which have been done to a standard Koha 2.2.5 installation in order to be provide a basic AMS integration for IMAR: “Simion Stoilow” Institute of Mathematics of the Romanian Academy library system. AMS integration One of the requirements of the customization was to allow a basic AMS integration. For each ISBN code the corresponding AMS code had to be found using a crawler. This was achieved by a value_builder plugin which consists of 3 parts:...
Updated 18-oct-2008: There is a great solution in Flex which I have used for this and this projects. Conclusion The problem of representing a graph on the web is not a solved one. On the desktop application side there are lots of tools which can handle large graphs with nice visualization but on a web page the choices are limited. For the given problem of representing a set of nodes connected through lines in order to illustrate the elements of an application I have tried the following:...
It’s now more than 16h of work for today. My mind hardly commutes any neuron. With pauses no greater than 5 minutes I have been sitting in my comfortable chair in front of my 2 computers codding, debugging, testing, software applications. I’m struggling with a fight I don’t know how to fight. I’m driven to work and to finish my tasks, to finish a work which never finishes. I’m driven to eat in order to give my poor neurons a bit more energy juice....
