A research group from Ateneo de Manila University invited developers in a Focused Group Discussion(FGD) on FOSS development at BCD Pinpoint, 4th Floor Bloomingdale Building, 205 Salcedo Street, Legazpi Village, Makati. The FGD was divided into two, the first had it on Feb. 26 and the second on Feb. 28, which targeted freelancers and employees respectively. The topics were: 1. Software / Deployment stack usage 2. FOSS advocacy 3. FOSS community Technical discussions were already going on before the formal one started. Michael Cole, an I.T. Manager, who was one of the speakers during Software Freedom Day 2007, gave a lot of his insights regarding the use of FOSS on the desktop space. He also revealed some of FOSS’s limitations at its current state. Re Alvarez, a system administrator, laid out some of his plans for FOSS usage on the company that he is working with. He gave out a lot of tips for newbies. Archie Cortes, a FOSS advocate and a full-time user since 1998, clarified t...

The virus consists of the following. C:\Windows\system32\fservice.exe and C:\Windows\services.exe The virus is a key logger. It sends an email message every time a connection to the internet is made. It blocks the Windows XP Protect Shield and System Restore services. Removing the virus: 1. Kill fservice.exe - Use TASKKILL /F /IM fservice.exe - If it doesn’t work on the first attempt, use NTSD -P [PID of fservice.exe] then quit the debugger to kill the task. 2. Kill services.exe - Kill the bogus one not the genuine services.exe - Follow procedure in number 1. 3. Delete all occurrences of fservice.exe and the fake services.exe - Do not delete the real services.exe found in C:\Windows\system32 4. Clean the registry for entries containing fservice.exe and the fake services.exe

Felices Pascua Y Prospero Año Nuevo!

Today is Gat Andres Bonifacio’s day. No work, no pressure, so I took the advantage of going to my aunt’s workplace to remove the so-called Jaymyka worm. All the computers were infected. Worm: Jaymyka Threat Level: Low Target Victims: Users viewing adult sites (Geez! Who did that in the office?) Description: It creates an autorun.inf file per drive with the following contents, [autorun] open=jay.exe ;shell\open=Open(&O) shell\open\Command=jay.exe shell\open\Default=1 ;shell\explore=Manager(&X) shell\explore\Command=jay.exe The autorun.inf file is paired with jay.exe. The jay.exe file handles the annoying duplication of files and some resource-hogging tasks leading to DoS attack. If this worm is able to infect the target device successfully, it attaches a file named mveo.exe at startup. This mveo.exe is responsible for the worm’s capability of regeneration. [Diagnosis] 1. Kill mveo.exe and jay.exe TASKKILL /F /IM mveo.exe /IM jay.exe 2. Delete...

Most users complain about the error pop-ups rooted from the ads attached to their Yahoo! IM clients. Turning off from the registry is the best way shun them. In the registry, [HKEY_CURRENT_USER\Software\Yahoo\Pager\YUrl] Set or add these values, Messenger Ad = * Webcam Upload Ad = * Webcam Viewer Ad = * Webcam Viewer Ad Medium = * Webcam Viewer Ad Big = * Change Room Banner = * Conf Adurl = * Chat Adurl = * Edit the file \Program Files\Yahoo!\Messenger\Cache\urls.xml, erase all the contents and leave 2 double quotes (” “), save it then mark as read-only.

In every programmer’s journey, the legendary “Hello World!” program excuses no one. So I wrote, compiled, then disassembled it. public class Hello { public static void main(String[] args) { System.out.println("Hello World!"); } } I fired up a hex editor to analyze the bytecode’s disassembly. This part contains the headers, class name and the superclass being extended . This is how a JDK 1.5-compiled bytecode looks. .bytecode 49.0 .source "Hello.java" .class public Hello .super java/lang/Object By default, a constructor is generated. Check that it constructs itself as an object of type ‘Object’ naturally because Java classes extend the ‘Object’ class. Here we have shown that a constructor is just a method. .method public ()V .limit stack 1 .limit locals 1 .line 1 aload_0 ; met001_slot000 invokespecial java/lang/Object. ()V return .end method Here’s the main method. .method...

Dealing with worm-infected Yahoo! Messengers in Windows XP is fun. Just apply the fix. Do not reformat because it is the lazy way of fixing things!

Mindanao Open Source Society (MOSS) held its 1st Hands-on Power Training at the ADZU Open Source Laboratory. It was totally a new experience for me since I really do not know how to organize events. There is always a first time as they say. I really thank God for making this event a success though not yet perfect but hopefully the next will be planned and organized well. This event is so memorable for me since I have learned a lot of things that are not just technically related to Free and Open Source Software. To Sir Fhics , thank you so much and I salute you sir! Sir Fhics is the head of CISCO Zamboanga. He is so down-to-earth, very kind, open-minded and a skilled man yet so humble. He is one of those skilled persons who never sets a gap between himself and those who are just starting up (newbies). He even considers himself a “droplet of water in the ocean of knowledge.” Again, thank you sir! I have learned not just pure networking stuffs from you but also values that ...

Nothing special really, I have just upgraded the processor from 1.7GHz to 3.0GHz with HT technology. The 1.7GHz (1.9GHz overclocked) processor is now for sale. Too bad I’m still using Intel processors. Hopefully after graduation I’ll be able to make my switch to the dark side of the force, AMD.

Web application development can be time consuming and complex. The development process can be simplified by using frameworks. A web application development framework contains a set of tools and libraries for easier development. Frameworks are preferred by enterprise developers since it simplify development process, reduce development time, improve readability of code, organize development and emphasize modularity. Using frameworks for enterprise development will surely make a team productive. Most frameworks use the Model-View-Controller design paradigm. The MVC design paradigm separates the data and user interface. Changes to the user interface will not affect the handling of data and the data can be restructured without changing the user interface. The MVC handles this by decoupling the data access layer (DAL) and business logic layer (BLL) from data presentation and user interaction through the controller.
