Halloween

It is a season when children enjoy collecting candles, jumping around sarcophagi, wearing dirty masks, and scaring other children(smaller/younger). TV shows are fun to watch. In the United States, children usually play snowballs during winter. Well, it is totally a different story here since children play waxballs during Halloween. Not forgetting adults, it is a season for filling stomachs with barrels of beer, bottles of wine, and gallons of coconut-fermented drinks otherwise known as tuba . I really do not enjoy roaming around burial grounds especially during Halloween for the reasons that, you will see people shouting at each other, throwing punches, showing knives, and trying to boast their clan’s supremacy among others. The fear of ghosts is not a thing to consider here, it is the fear of being unable to withstand adults looking for troubles no matter how hard you try ignoring their fun. This is true to cheap cemeteries that are maintained by the local government unit. Comp...

Some updates on my Gentoo box

Get in position and wait for my go. I recompiled the kernel applying Con Kolivas ‘ kernel patchset for linux-2.6.18. Accordingly, his patchsets are designed to improve system responsiveness with specific emphasis on the desktop, but suitable to any workload. Feedbacks show that it scales well for a typical desktop use. If you want to try this out, here is a comprehensive walkthrough that will get you on your feet along the way. I also felt the need of updating my Xorg. I had a smooth shift from Xorg 6.9 to Xorg 7.1. So far so good. Firefox 2.0 rocks as well! There are obvious improvements so grab yourself one. Currently, it is masked by x86 keyword in the Gentoo Official Portage so just deal with it.

Crackmes: cyrex’s Linux CrackMe

Find the correct password to get the good boy message it would be great for an solution how you solve this , and with what i solve this with the standard GNU Debugger (gdb) Difficulty: 1 - Very easy, for newbies Platform: Unix/Linux, etc. Language: C/C++ [Solving the Crackme] Solving crackmes is fun but if you screwed up, it sucks big time. Thank goodness, heavy tasks are over.

ISP lock-ins

Globe Broadband and Bayantel please invest here as soon as possible. We need the quality of services that you offer. Majority of the broadband subscribers here are not that satisfied. One year contract is not worth it. I have received the first bill already. Does it mean that I will be suffering 11 months more? Geez! pldc ka kasi tol! ang hina ng broadband mo! ano yan pentium poor? sm*rt broken ata yan eh! [bayantel only] join now! tol, ipconfig /release tapos ipconfig /renew lol! I can’t even access the website of Mindanao Open Source Society . Damn it. Hoping for better days.

Bad luck

This is a program that simply extracts numbers from buffered input. I do not have any idea why this didn’t work. I got a zero. input: mov ah, 0ah ; buffered input sys call lea dx, strptr ; load effective address int 21h ; call kernel mov ah, 02h ; write character to stdout sys call mov dl, 0ah ; issue carriage-return int 21h ; call kernel lea si, string ; set source index to start of string mov cl, [strlen] ; set loop counter here: mov dl, [si] ; place current character in dl cmp dl, '0' ; compare if below '0' jb traverse cmp dl, '9' ; compare if above '9' ja traverse mov ah, 02h ; write character to stdout sys call int 21h ; call kernel cmp dl, '$' ; check end-of-string sentinel je exit traverse: inc si ; increment source index pointer loop here exit: int 20h ...

Happy Fiesta Zamboanga!

Viva! Nuestra Senora del Pilar. Today is the feast of Our Lady of the Pilar, our city’s patron saint. Here is a description of the city where I live in. A very peaceful place that is. I guess I won’t be enjoying the feast today since I’ll be finishing our OpenGL project. In my list, it also says that I’ll be writing a simple C program today incorporating Balanced Trees . Well, it’s my own approach to file system writing.

RX Band Breakout conquered!

We did our best! We burned the stage! A video of our performance will be uploaded in youtube soon. I will post the notification here. We got the most awards. It was indeed a blessing! 1) Best Bassist - Joset Zamora 2) Best Vocalist/s - Bon Padayhag, Macky Alger 3) Best Drummer - Daryll De Leon 4) 2nd Place - Junkyard Congratulations to the winners as well. You did great! Thank you Dream Radio RX 93.1 ! [Resolution] No gigs before graduation day. Now it’s time to get the Reiser4 File System Driver for Windoze XP done. Yeah, that’s our thesis. God bless us all.

Binary Trees

A tree has a finite set of elements called nodes. It has a unique node called the root node, where the remaining nodes are a disjoint collection of subtrees. A binary tree is a tree whose elements have two children at maximum. It is considered as a data structure composed of elements that are characterized by two link fields, left and right children. A leaf node contains 0 children meaning both children point to a NULL value. A binary search tree is a special type of a binary tree . These terms are sometimes used interchangeably in some articles, so do not be confused. For this purpose, I’ll limit my article to binary trees in general. First let’s define the structure to be used. #include <stdio.h> #include <stdlib.h> typedef char DATA; struct node { DATA d; struct node *left; struct node *right; }; typedef struct node NODE; typedef struct NODE *BINTREE; [Creating a Binary Tree] Dynamic allocation. BINTREE new_node() { ...

RX Band Breakout

RX Band Breakout will be on October 9, 2006. It is going to be a tough competition though. Most competing bands are extremely good! So acting like a duck on stage would surely drive you down. We want to burn on stage and fire them up with our solos. Sad thing is that, I do not have enough time for practice so I searched for bass solo stuffs. I found a lot of cool Brazilian scales incorporated in a bass solo and all that. Which also lead me to rank bassists who happened to be my influences. I wish could play well like them. Here’s my ranking. 1) Victor Wooten - Versatile 2) Bill Dickens - Versatile 3) John Myung (Dream Theatre) - Progressive Rock 4) Romel (Barbie’s Cradle, Freestyle) - Progressive Folk 5) - name - (P.O.T.) - Funk Rock 6) Flea (Red Hot Chili Peppers) - Funk Rock 7) Nathan (Rivermaya, Kapatid, Bamboo) - Rock 8) - name - (Wolfgang) - Rock 9) - name - (Razorback) - Rock 10) Stuart Ham - Jazz For as long as we’ll be able to burn the stage, it doesn...
