First Semester, the aftermath of ondoy...pepeng and ramil

At last, I survived the First Semester of my Third year. So, review lang po ako about the previous semester. First, masasabi kong medyo bitin ako sa first semester. Kasi, in my own perception e may mga topics na hindi naidiscuss sa amin kasi sa dami ng walang pasok at mga suspension of classes. Sayang, pero wala naman ako o tayong magagawa sa mga suspension of classes at mga walang pasok dahil natatapat naman kasi sa mga holidays. Speaking of suspension of classes, napuna ko na itong semester na ito e madami kaming walang pasok una at una pa lang noong dahil sa H1N1 spreadout sa Campus, almost 4 days yun. Then, sumunod yung national mourning dahil kay Tita Cory. Anjan na rin yung mga sunod-sunod na walang pasok na monday dahil sa mga national holidays at ang huli naman ay dahil kay Ondoy na kung saan naman ay na-stranded ako ng halos 15 hours sa bus.

In-review, iisa-isahin ko yung mga ginawa ko sa mga kinukuha kong mga subject this First Semester:

General Physics w/ Electronics Lec/Lab

Saturday Class - 12:30 to 6:30 PM

First, ok yung naging prof namin dito. Madami din akong nakuhang wealth of information sa kanya. Elibs nga ako sa prof ko kasi Physics Prof siya at the same time prosecutor siya ng mga military cases sa Ombudsman. Sulit naman mga pinasok ko every Saturday of First Semester. Noong Prelim, bumagsak ako sa kanya pero bumawi naman ako sa kanya ng Midterm and Finals.

Basic Accounting

Tuesday and Thursday - 12:30 to 2:00 PM

Mahirap sa una, pero dahil passionate sa amin yung naging prof namin at sa mga further explanations nya sa amin, naiintindihan ko ang accounting kahit paano. Importante kong natutunan sa accounting is yung accounting balance, yung T-Account, yung Account Cycle at Adjusting Journal Entries. Napakaimportante ang Adjusting Journal Entries kasi doon mo talaga malalaman yung tunay na Expense at Income mo.

Statistical Method (Math)

MWF - 9:00 to 10:00 AM

Nakakahiya, pero yung prof ko dito sa Statistical e naging kaklase ko dati sa PE (Badminton). Matalino siya, akalain kong maging prof ko siya? Halos kasabay ko siya kasi 2005XXXXX ang student number namin e. Anyways, ang importanteng natutunan ko sa Statistical Method is yung Statistical Inferrence at Sampling Techniques dahil magagamit daw namin siya sa Thesis.

Operating System Lec / Lab

Tuesday and Thursday - 9:00 to 10:00 AM

Friday - 3:00 to 6:00 PM

Maigi na lang at na-survive ko tong subject na ito. Ito ang nakapagpatunay sa akin na medyo mahina ako pag dating sa algorithm. Pero sa bandang huli, naiintindihan ko naman siya. Lalo na yung MLQ at MLFQ, kapag yun yung algorithm na pinapacompute sa amin sa one-half yellow pad, na-realize ko na pwede pala pagsamahin ang FCFS, SJF, ROUND ROBIN, Pre-emptive at Non-Preemptive Priority. Oo, medyo naintindihan ko siya, pero noong pinagawan kami ng project at iaaply na namin siya sa kahit anong platform, hirap kami, kaya naging gabay ko ang internet at nag-download ako ng sample program and codes. Somehow, nakagawa kami dahil naging guide namin yung sample program and code. Salamat sa Google! Hehehe! Wala e, ginawan ko na lang ng paraan kasi gahol sa oras due to a week suspension.

Advance Database Management System Lec/Lab

Tuesday and Thursday - 10:00 to 11:00 AM

Wednesday - 11:30 - 2:30 PM

Dito sa subject na ito nagka-idea ako sa MySQL. Hindi kasi naituro sa amin yung MySQL ng prof ko dati sa Dynamic Webpage Development e. Isa sa importante na natutunan ko dito sa ADBMS is first, yung normalization. Sabi ng naging prof namin dito, sa industry daw, hanggang third normal form lang daw. Tapos diniscuss sa amin kung ano yung Datawarehousing at saan siya ginagamit at siyempre ang SQL using MS SQL Enterprise Edition. Isa sa importante din pala na kapag ke-create ka ng tables ay dapat unahin mo yung table na walang foreign key hanggang sa table na may foreign key kasi nagkaka-error kasi kung di sunod-sunod yung ike-create mong table. Tapos, ihuhuli mo naman yung INSERT command.

Object Oriented Programming Lec/Lab

Tuesday and Thursday - 3:00 - 4:00 PM

Wednesday - 3:00 to 6:00 PM

Sa totoo lang, i Hate Java! Pero wala akong magagawa, kasama siya sa curriculum namin e. Anyways, di naman sa Java nagfofocus yung subject na ito e. Akala ko dati, ang OOP ay para lang sa Java, mali ako. Dahil kahit saang programming and scripting languages pala ay applicable siya. Iniisip ko rin dati kung para saan ba ang Object Oriented Programming? Sinadya ko talaga na hindi ito itanong sa professor namin dahil baka naman ituro sa amin ng paunti-unti at hanggang sa matutunan namin ang concept ng OOP. Para lang siyang Data Structure and Algorithm dahil umiikot ang OOP sa functions, procedure, class and methods. Kung tama yung pagkaunawa ko sa OOP, iniiwas ng OOP ang redundancy sa codings. I mean, mas proper kasi kung gagamitan mo ng method (getters and setter) ang isang code kung possible na mangangailangan ito ng parehas na coding. Sana, kapag gumagawa na kami ng thesis ay mai-apply ko o namin ang OOP. Isa sa mga nakita kong scripting and programming language na gumagamit ng OOP ay ang Wordpress, dahil everytime na nagda-download ako ng themes para sa wordpress ay naka-class yung mga php codes.

To be continued

Parang hirap ako ngayon, pero mapagcha-chagaan

Good day to everyone. Naka-third week na ako sa school at parang hirap ako sa OS. Speaking of OS, tungkol siya sa CPU Scheduling / Algorithm. Maigi na lang at approachable prof ko doon pero sa totoo lang naguguluhan ako sa turo niya. Noong una, naiintindihan ko kasi wala pang idle time kapag sinasagutan yung Gantt Chart sa FCFS. Sabi ng prof ko, isa sa madaling scheduling ang FCFS. OO, naniniwala naman akong madali kapag hindi laktaw-laktaw ang arrival time niya pero kung laktaw at kapag hindi nag-match ang RQ at sa dulo ng gantt chart e mali na ang computation sa AveTT at AveWT. Pero sa tingin ko, kakayanin ko to kasi nagpa-photocopy ako ng module ng prof ko sa OS.

first sem inception

Finally, after a long time nakapag-post din ako. Nakilala ko na din yung ibang mga professors ko both major and minor subjects, pero papalapit na ang Prelim Exams at kokonti pa lang nadidiscuss sa amin.

I think, I'm lucky with all of my subjects for this semester lalo na sa mga major subjects ko. Even in Physics na dapat e krinedit na lang sana ng IT department yung dati kong Physics sa ECE ko dati, sayang.

Bago yung professor ko sa Operating System. Sabi niya sa amin noong nagla-laboratory kami e swerte daw kami sa kanya kasi sa lahat ng professors daw na nagha-handle ng OS Lec and Lab e maituturo niya sa amin ng maayos yung binigay niya sa amin about CPU Algorithms.

Suspension of Class?

Nag-start na ang klase namin noong June 15. Medyo ok at excited ako sa pasukan. Na-meet ko na ang mga professor ko pati na yung mga kaklase ko. Yung iba kong mga kaklase, hindi nabago. Pero marami rin ang panay bago.

Bininyagan ko na din yung bago kong Bag. Medyo may kalakihan pero sulit naman kasi marami akong notebook na binili para sa Tatlong Major Subjects at sa Physics.

Ang pasok ko ay lunes hanggang sabado. Mas worst ang lunes ko kasi isang subject lang ako from 9-10 A.M lang ako. Gayundin ang Biyernes ko. From 9-10 may klase ako, then kasunod nito ang laboratory ko sa Operating System from 3-6 P.M.

It's all in my bag Part 1

What is the inside of my bag during first and second semester?
2008 - 2009 First and Second Semester

1. A Brown Bag - I bought this bag in SM Bacoor last 2007. I remember, it's Php. 500. Sulit siyang gamitin, matibay.

2. Thickler Notebook - Kahit luma, binaligtad ko na lang. Marami kasi akong nabiling refiller leaves nito so kung bibili pa ako ng bagong notebook noon e sayang naman.

3. Perfume - It's Hugo Boss. Inarbor ko kay Papa. Gwapo sa pakiramdam... hanggang pakiramdam na lang. Hehehe!

4. School ID - No ID, No Entry!

5. Coin Purse - Kapag marami akong coins, dito ko nilalagay kasi nalalaglagan ako ng barya kapag sa bulsa ko lang inilalagay. Malaki pakinabang sakin nitong coin purse na ito na regalo pa sa akin ng Lola Fe ko noong last Christmas.

School days is getting near again! So that, this article is dedicated to my school and for all concerns.

In my school, I have had good teachers who are really, really good. They teach and explain everything well and really seem to be experts in their field of study. But I also had teachers who know only a little bit and did not really teach well, but were pretending to know what they really did not know.

I know that computer education world is a fast paced world that there is always something new and being a teacher may be hard for them to catch up. That is why the teachers that I like are those that say “I don’t know” if they really do not know and just promises they will check it out and by the next meeting, they did some research and gives you a good answer. The teachers at Adamson IT&M that I hate, are those that do not have the right answers, and pretend they know everything, and sometimes what they are saying are wrong.

I am a good student and I'm not dumb to oppose them and just accept what they say even if I know it is wrong. Kaya naman if I know that their teachings are wrong, I'll search for the right one. Opposing a teacher hits their pride and sometimes gives me a low grade.

XHTML, why not HTML?

XHTML, the standard, was first released back in 2000. Roughly five years later we begin to see major websites revised to use this standard. Even the favorite whipping boy of standards-compliance punditry, Microsoft, presents their primary homepages, msn.com and microsoft.com in XHTML. Standards compliant XHTML sites are still the minority. The reason is simple. When the W3C released the new standard, the rest of the web running on HTML did not cease to function. Nor will the rest of the web, written in various flavors of HTML, cease to function any time soon. Without any pressing need to conform to the new standard, designers continue to use old, familiar methods. These methods will perform in any modern browser, so why bother switching?

These sentiments are similar to ones I experienced. A kind of "if it's not broke, don't fix it" mentality sets in. Whether HTML was "broken" or not is a different argument. To the casual Internet user, their standards are fairly direct. If a site displays without noticeable error and functions to their satisfaction, these standards are met. Whatever additional steps the browser took to make such display possible is irrelevant to most users. This kind of mentality is difficult to overcome in designers accustomed to their old methods.

Technical obstacles to adopting XHTML may be quite steep as well, especially as regards large, existing websites with complex scripting. Yet the time may eventually come where yesterday's "tried and true" HTML is little more than an ancient language, unable to be interpreted by modern electronic devices. Whether one agrees with the direction the W3C takes in the development of HTML is irrelevant, you are just along for the ride. With some perseverance, getting the hang of XHTML is possible. In form, it is not as different from HTML as Japanese is from English. Knowing HTML grants a basic knowledge of the language, it simply becomes a matter of learning a particular dialect. Even an original nay-sayer such as myself managed to do it.

Benefits of XHTML
There are 2 primary benefits to using XHTML. First is the strict nature of valid XHTML documents. "Valid" documents contain no errors. Documents with no errors can be parsed more easily by a browser. Though the time saved is, admittedly, negligible from the human user's point of view, there is a greater efficiency to the browser's performance. Most modern browsers will function well in what's usually referred to as "quirks" mode, where, in the absence of any on-page information about the kind of HTML they are reading, present a "best guess" rendering of a page. The quirks mode will also forgive many errors in the HTML. Modern browsers installed on your home computer have the luxury of size and power to deal with these errors. When browser technology makes the leap to other appliances it may not have the size and power to be so forgiving. This is where the strict, valid documents demanded by the XHTML standard become important.

The second benefit is in the code itself, which is cleaner and more compact than common, "table" based layout in HTML. Though XHTML retains table functionality, the standard makes clear tables are not to be used for page layout or anything other than displaying data in a tabular format. This is generally the primary obstacle most designers have with moving to XHTML. The manner in which many designers have come to rely on to layout and organize their pages is now taboo. Simple visual inspection of XHTML code reveals how light and efficient it is in comparison to a table based HTML layout. XTHML makes use of Cascading Style Sheets (CSS), which, when called externally, remove virtually all styling information from the XHTML document itself. This creates a document focused solely on content.

XHTML makes use of "div" tags to define content areas. How these "divisions" are displayed is controlled by CSS. This is known as CSS-P, or CSS Positioning. Trading in "table" tags for "divs" can be tough. Learning a new way of accomplishing an already familiar task is generally difficult. Like learning to use a different design program or image editor, frustration can be constant. Looking at "divs" as a kind of table cell might be helpful, though they are not entirely equivalent. As required by the XHTML standard, always make sure there is a DOCTYPE definition at the top of the document. This is not only required by the standard, but it will force Internet Explorer 6, currently the most common browser, to enter its "standards compliance" mode. IE6 and Firefox, both operating in standards compliance mode will display XHTML in much the same way. Not identical, but far better than IE6 operating in quirks mode. Learning how to iron out the final differences between displays is the final obstacle and can require a bit of tweaking in the CSS.

Clean code has multiple benefits. It creates a smaller page size which, over time, can save costs associated with transfer usage. Though the size difference may appear small, for someone running a highly trafficked site, even saving a few kilobytes of size can make a big difference. Further, some believe search engines may look more kindly on standards complaint pages. This is only a theory, though. In a general sense, any page modification that makes the content easier to reach and higher in the code is considered wise. Search engines, so it is believed, prefer to reach content quickly, and give greater weight to the first content they encounter. Using XHTML and "div" layout allows designers to accomplish this task more easily.

Conclusions
XHTML is the current standard set by the W3C. The W3C continues development of XHTML, and XHTML 2.0 will replace the current standard in the future. Learning and using XHTML today will help designers prepare for tomorrow. Valid XTHML produces no errors that might slow down a browser, and the code produced is clean and efficient. This saves in file size and helps designers better accomplish their search engine optimization goals. Learning XHTML is primarily about learning a new way to lay out pages. Though frustrating at first, the long term benefits far outweigh any initial inconvenience.

Tutorial - Forum Sites and E-book

May mga instances na hindi mo maintindihan ang lecture ng professor mo sa mga major subjects. For example, ang course mo ay IT at Computer Science kung saan programming and scripting ang mga subjects sa course na ito. Nagiging complicated ang subject kapag wala kang natututunan dahil sa nalilito ka sa subject o sa nag-tuturo.

Ako naman, dalawang paraan lang ang ginagawa ko para hindi ako bumagsak at the same time e maunawaan ko't maintindihan ko ang mga nilelecture sa'min ng prof namin sa major:

1. Mag-tanong. One of the most powerful key for the learners is to observe and to ask. Mas malinaw ang isang lecture ng isang professor kung may nagtatanong. Katulad kong slow learner, hindi ko hinaayaan ang isang lecture na matapos hangga't hindi ko maintindihan. Swerte nga ako nitong mga nagdaang mga First and Second Semester (2008-2009) kasi karamihan naman sa mga naging prof ko ay approachable at mahahaba ang pasensya which is dapat ganoon sila.

2. Be Resourceful. Kung hindi mo nga naman talaga maintindihan ang isang certain topic o lesson sa lecture nyo, why you don't try to ask to others? Like me, member ako ng convergence forums. Natatanong ko sa kanila ang mga bagay na hindi ko naiintindihan about topics in IT. At nasasagot naman nila ito kasi nga ang concept ng convergence forums is to share thoughts, minds and knowledge by simply answering questions. At siyempre, hindi naman ako madamot, kapag may nag-start nang mag-tanong sa isang thread depende sa topic na nalalaman ko naman ang sagot, e sinasagot ko naman ito. At sa forum site, nabui-build up jan ang isang social community ng mga learners at mga masters sa IT.

Pero siyempre, wag mong asahan na masasagot din agad nila yung gusto mong malaman. Instead, try to use Search Engine and type the keywords of the topics you wish to know. Sa t0p ten results, naibibigay sa 'yo ng Search Engine ang recommended site para sa topic na hinahanap mo para pag-aralan mo.

Isa pa, kung mahilig kang mag-basa, maganda rin siguro na puntahan mo ang mga tutorial sites at mga free e-book downloads. Kasi detalyado ang mga tinuturo doon. Or else, sa youtube pwede mo din i-search ang mga topics na gusto mo ding malaman.

My PHP Days in AdU

Guys, ang next na i-po-post ko dito ay ang mga natutunan ko about PHP sa Adamson. So, kung aware po kayo about PHP e mas lalo naman po ako. Unti-unti kong naiintindihan at nauunawaan kung bakit napaka-halaga ng C++. Kasi, extensive ang kanyang coding sa ibang programming and scripting languages kagaya sa PHP, almost the same din ang nito sa C++ pero iba nga lang ang input-output.

Probably, ipo-post ko po ito if I have a free time.

A simple nested for statement in PHP

Recently, I read some blogsites and forums about conditional statements in PHP. And i found out that there are some similarities when you are making some codes in C or C++ and in PHP. Now, if you have a strong foundation in C or C++ then it is easy for you to study the PHP scriptings.


Below are some of my sample coding (or scripting) in PHP ab out nested for condition statement.

save it as index.htm | save it as validation.php

Sample Output

This is a sample output. When you copy the index.htm, may i request to please save it in one folder (for formality).








And this is the sample output. Better yet, to do this, you must read or review your subject in Data Structure and Algorithm about how to do this one.

Ano ang SEO?

Guys, lalo na sa mga ka-klase ko dati sa webpage composition and development sa AdU, para sa inyo itong topic na ito.

Alam ninyo at alam ko din na hindi ganoong kadali mag-initiate ng website. At lalo na ang mag-initiate ng niche sa isang website at blogsite na kagaya ng nababasa nyo ngayon. Bago ko sinimulan itong blogsite kong ito, marami akong bagay na inisip.

So atin na pong simulan ang SEO. By the way, what SEO stands for...?

SEO stands for Search Engine Optimization. Para saan naman ito? Well, alamin natin.

Na-isip nyo po ba, meron na kayong website na naka-host na sa isang web hosting, pero kapag ti-nype nyo po ito sa any search engines like Google or Yahoo e hirap ninyong makita?

At dito po pumapasok ang salitang SEO. Ang konsepto po kasi ng SEO ay upang pasikatin ang ginawa ninyong website sa tatlong major Search Engines na siguradong nasa Homepage ninyo: ang Google, ang Yahoo at ang MSN.

Bakit kailangan ng isang website ang SEO?

Kinakailangan po talaga ng isang website ang Search Engine Optimization. Marami sa mga kumpanya ay may kanya-kanyang website, karamihan ay corporate website o business website (eCommerce). Ang goal ng bawat kumpanya na mayroong website ay mai-market nila ang kanilang produkto at serbisyo sa pamamagitan ng Internet. At alam natin na kapag sinabi nating Internet, ito ay Broad and Wide ang sakop nito sa lahat ng field of interests.

So, bakit pa nga kailangan ng isang website ang SEO?

Una, kapag wala sa listahan ng search engine ang inyong website, walang sense. So, kagaya ng Google, nag-oofer sila ng AdWords at AdSense. Ang AdWords ay isang Online Advertisement na serbisyo ng Google na kung saan ang inyong website URL ay nai-didisplay nila depende sa content o Niche ng hinahanap mong website sa kanilang search engine o di naman kaya ay sa pinasukan mong website na may AdSense. Ang AdSense naman, na serbisyo rin ng Google, ay isang Online Advertisement na kung saan ang mga webmaster ay nilalagay ang mga advertisement ng AdWords sa kanilang website na kada click ng mga viewer sa advertisement na naka-post sa kanilang website ay may centavo silang kinikita.

Pangalawa, Sayang ang investment sa website kung hindi nga ito sikat sa mga Search Engines. Isipin ninyo kung gaano ka-epektibo ang Online Business kapag sikat ka sa Search Engines?
