Making you feel loved was the easiest thing I have ever done before. It’s just sad to think that things just changed. I wish I could turn back those days. The times when we sat down under a tree, observed the fading horizon, held hands and stared at the crimsoning sun. I know how destiny fools us. If destiny asserts that we are not for each other, then I would fight destiny just to have you in my arms forever. I love you my everdearest. I’m sorry for what had happened to the rose. It’s not too late though, I can still take care another bud for you.

Simple programming stuffs save me from insanity. This a86 assembly program tells if str1 is a palindrome. start: cld mov cx, 7 lea si, str1 lea di, temp reverse: mov al, [si+6] mov [di], al inc di dec si loop reverse mov ah, 09h lea dx, temp int 21h cld mov cx, 4 compare: lea di, temp lea si, str1 repe cmpsb jne exit mov ah, 09h lea dx, yes int 21h exit: mov ah, 4Ch mov al, 00 int 21h int 20h str1 db 'racecar$' yes db '',10,'string is a palindrome!$' temp db 8 dup ('$') [Middle-East Crisis] Israel, known as the chosen people of God called a thousand reservists in a possible prelude to a ground offensive against Lebanon. Accordingly, they have to clean up bunkers and tunnels that are invulnerable to air attacks. Isn’t it ironic...

I can still remember way back then, I was five years old when I had my primary hobbies, hunting, fishing, and shooting-range. Today, we went to Sinubung, a semi-dangerous place located in the far west coast of Zamboanga City and is known for its shore having huge waves and numerous sea urchins. We have gone fishing. It was fun riding my grandfather’s motor-operated vinta again though I am deeply saddened with what had happened today. The last time I set foot on that vinta was 15 years ago. I can still remember my grandfather pulling the nylon with a huge squid hooked up. Of course, the squid fired up a black tint. Because of that black tint, and the times when I threw up while riding the vinta, I have something now which I call memories worth remembering. Awhile ago, we did the same but no squid and from what I have observed fishes are already scarce! We spent almost three hours, changing position from time to time on the sea. I was the one throwing and pulling the anchor everyt...

Red Horse Muziklaban is fast approaching. Tomorrow will be the qualification or shall I say audition. One composition down. I am still trying to come up with a nice riff for the adlib. Hoping to impress the judges tomorrow. [Programming] I am just messing up with DOS Assembly. I started out programming in 32-bit protected mode, now broadening my knowledge by diving into 16-bit real mode. I have nothing new these days, just reviewing C++. Signing off through a quote by Albert Einstein “Information is not knowledge.”

Congratulations Manny Pacquiao! He was once a singer of a local band in Gen. Santos City. Look at him now, he is the most influential person in our nation and probably one of the most influential persons around the globe. I was really fascinated by his fight with Oscar Larios. He has become faster than ever. Incomparable vigor that is! Raise it up Manny. More power and advertisements ahead. On the other hand, I pity Oscar Larios, he was a great fighter. I admire his sportsmanship and humility. He is one of the cheerful and honest boxers I’ve ever seen. His courage is a deadly weapon that one shouldn’t take advantage of. Maintaining his mind in equilibrium state could have driven Manny on the floor. [Globe Telecom] What is happening? I couldn’t send and receive SMSs. Calling does not solve the issue either. Hoping for better services in the future.

GDT contains a number of entries, Segment Descriptors . Usually each is 8 bytes long and marks the starting point, length, and access rights of the segment. It is stored in memory of course. The address is stored in a special 48-bit CPU register called Global Descriptor Table Register (GDTR). The lower 16 bits inform the size of the GDT while the upper 32 bits inform the location of the GDT in memory. The GDT itself is a 64-bit long entries. These entries define whether the current segment that the processor is running is for Ring 0 or Ring 3. Ring levels are restrictions, Ring 0 is for system use while Ring 3 is for application use. Such protection exists to prevent applications from causing the kernel to crash and to tell the processor which instructions are valid. –snipped–

ADZU Open Lab will be switching to Edubuntu 6.06 Dapper Drake! Wee! Expecting Ubuntu sovereignty in the University! More power Ubuntu Linux Development Team. A Freedom Toaster empowered by Shuttleworth Foundation is badly needed in our University. The network administrator, Sir Greg, also suggested Xubuntu 6.06 in the College Internet Access Area (CIAA). Well, it’s easy as one-two-three.

It’s good to be back to one’s abode. I haven’t been blogging lately for the reason that my dad was confined and there were no other who could watch over him except me. Good thing that my dad’s okay now. Got to go, have to finish the enrollment process. God bless.

Twenty factorial? Thank God for all the blessings especially the gift of life. Thank you mom and dad for taking care of me. Thank you everyone! Happy birthday to me! I am no longer a teenage lad. I could not believe it. Time flies so fast.

[Previous Post] Sorry I forgot the private flag because I was in a hurry awhile ago. I hope it didn’t deface Planet Ubuntu-PH. [OS Development] Global Descriptor Table conquered! Nothing special, more tasks ahead. So far so good. Linux 0.01 is cool and MiniOS (Minix) too! Hail to you Linus Torvalds and Andrew Tanenbaum.

Thinking of the song? No, definitely not Kala’s hit in the Myx Daily Top 10. It was 31 down 7 o’clock in the evening, the last day of our training. The sky was darkening and the wind blew softly as I walked toward the terminal. Going home later than 6 o’clock in the evening is such a waste of time I heard myself whisper. Before taking the jeepney in line, I have decided to sit down and buy a bottle of coke in a bakery situated near the end of the terminal. While taking a sip, I observed people passing by. Definitely not Manila, whispering to myself and reminiscing the events a year ago. 5 minutes would be long enough for me to begin sipping air so I took a jeepney. I have waited for the jeepney to be filled up. Not exceeding 10 minutes, the wheels started rolling as expected. This year is going to be the hardest school year ever. Again, talking to myself. Anticipating sleepless nights, hardworks, additional duties or obligations, etc. Then suddenly while thinking o...

This is a late post. Simply explains how the kernel sits in after grub.

Well I guess keeping myself busy would be wise enough.

[Da Vinci Code] I have been to the movie house recently and watched this controversial film. The book, despite its ever-growing popularity, did not interest me that much since I equate my faith with a sword mightier than Tireal’s Azurewrath. I was saddened deeply when I reached the movie house and saw numerous people there oozing with their teenage curiosity. First of all, have they been to church? It’s Sunday for pete’s sake. Why would they prioritize watching a film that is against their religion without even thinking that they have their obligations? Dan Brown’s manuscript is really a work of art and no question about that but people should remember it as a fiction book and nothing beyond. To all those who have read the book or have watched the film, try reading The Da Vinci Code Decoded written by a Jesuit priest. [OS Development] Do not write your own operating system. An information available globally that could be considered as a blackhole where o...

I have emerged vim-7.0-r2 just recently. Preparing a lot for our college thesis. Not excluding the amount of food intake. Reading the intel manuals from hell. Heavy bondings with bochs, vim, nasm, gcc, ld, strace, objdump, hexedit, as, etc. Requesting a divine intervention for strength.

I was sidetracked from my C++ programming ( Battle for Wesnoth ) by the school’s Senior Summer Trainings 2006. After MySQL and PHP, and a week OJT at Zamboanga Freeport (OMED IT Solutions), the dark side of the force has arrived, Java Programming. We are currently being trained by Ma’am Ebony Domingo and some CS upperclasses who already received their respective diplomas last March of this year. Their spirits of magis uplift my morale and drive me to be more optimistic especially in dealing with a language that I’m not quite familiar with. Java is known for its being a platform independent language, equipped with an auto garbage collection mechanism, etc. (I don’t want to elaborate more on these). What I am trying to point here out is that, one of Java’s assets, which is the auto garbage collection, is also possible in C++ using an auto pointer . Now, how is this possible? What an auto pointer does is, it owns a dynamically created object and automa...
