Rawak

Memudahkan orang

Pernah terfikir tak dah berapa ribu kali kita isi borang? Dari sekolah sampai masuk uni sampai la ke alam pekerjaan. Isi borang lah kerjanya. Dalam borang tu mesti minta 3 benda, nama, IC dengan alamat. Tak rasa meluatke bila orang tanya benda yang sama berulang kali? Cuba pergi jumpa lecturer tanya dia satu soalan. Lepas 10 minit tanya lagi soalan yang sama. Lepas tu ubah soalan sikit, tapi maksud sama macam 2 soalan pertama, pergi tanya sekali lagi.

Bila kita nak isi borang UPU (permohonan masuk ke ipta), kita kena isi nombor IC, nama ibu kita. Takkan dekat JPN (jabatan pendaftaran negara) xde maklumat ni? Nak buat IC mesti kena ada surat beranak, yang sememangya mesti ada nama ibu dan bapa. Kenapa tak link antara jabatan2 kerajaan maklumat ni. Let say bila pegi LHDN utk buka file cukai pendapatan, isi IC je, terus otomatik maklumat pribadi yang tersimpan dalam sistem JPN dieksport ke dalam sistem LHDN


Tak payah nak membazir kertas isi borang maklumat peribadi, tak payah nak upah ramai penjawat awam, xde masalah berhadapan dengan kerani kounter dengan muka "jangan ganggu saya".
Of course, untuk mengelak privacy issues dan indentity theft, bukan semua kakitangan awam boleh asses maklumat orang ramai. Certain people je. Buat sistem log in supaya sesiapa yang cuba asses maklumat ni akan di tag. Just my two cent


Nak mengampu tapi tak mampu

Pada suatu hari di majlis kenduri kahwin, duduk semeja dengan strangers. Antara banyak2 strangers ni, ada seorang auntie

Auntie: adik nak ayam? aunti ambilkan

Aku: boleh jugak. nak dada (bahagian dada, jangan fikir bukan2)

Auntie: eh tak boleh, auntie nak bahagian tu.

Aku: ok.....

Nampak tak permainan auntie ni? Ingatkan saja2 nak tolong rupa-rupanya ada ayam dalam timbunan nasi

Member 1: nak makan mana ni?

Aku: mana2 pun boleh

2 minit kemudian

Member 1: Nak makan mana ni?

Aku: kedai X la

Member 1: mahal

Aku: ha tuh, kedai M

Member 1: tak menarik

1 minit kemudian

Member 1: cakap la nak makan kat mana

Aku: ......

#3

Member 2: Bro, brapa ringgit satu kepala, nak bajet ni

Aku: Ikut la brapa pun. Aku ok je

Member 2: Aku nak tanya ko la ni

Aku: ok..50 ringgit

Member 2: mahal sangat la. Pokai la aku. 20 ringgit je la

Aku: okok



Kenapa banyak aku rasa banyak orang yang offer "fake courtesy" ni? Hairan betul. Nak something tapi tak berani nak cakap terus terang. Bajet mcm aku akan tolak permintaan pastu hina, bagi komen  ke ape. Tak pernah sama sekali. Kalau orang minta something dari aku, dan aku tak boleh bagi, aku cakap je tak boleh bagi dan sebab-sebabnya.

Takdenye bila orang nak tengok jalan kira assignment, aku cakap,"tak boleh, aku dah hantar. Rajin la sikit. Aku stay up nak buat benda alah ni." Sebab mana aku tahu sebab2 dia nak minta tengok assignment tu. Maybe  dia dah siap, cuma nak compare jawapan. Maybe dia betul2 terlupa nak buat. Aku cuma akan cakap," tak boleh, dah hantar"

Mungkinkah orang2 sebegini sebenarnya takut dengan bayang-bayang sendiri? Diorang tahu bila diorang berada di tempat aku, diorang akan bagi komen yang tak betul dan kurang enak didengar.


Ok masa untuk layan series.

Processor, ram & graphic card

There is confusion among buyer when they looking for new pc. Typical question they will ask the salemen is..

1)Is it intel I3, I5, I7 or amd
2)Isn't amd pc can get overheated 
4)How much ram this thing have?
5)Can i play game with this pc?


The salesman will tell them this pc spec will blow their mind away, this pc have 50GB of GDDR10 RAM, this thing have AMD processor, great for playing games, he can play Need Speed : Speed Demon Fantasies Comes True without lag. And if the customer  choose to buy this pc, he will upgrade it to 60GB of RAM, just add RM100.


Wrong, wrong wrong. First of all the salesman will say just about anything to convince you to buy at his shop. He could say,"you should buy this pc because this particular pc is like a light, shining in darkness."


Or god forbid he say prophet told us to choose this pc. What the salesman didn't say that? Because its obviously false and will not work.

How to choose correct hardware for your gaming pc?. I found this awesome website, tweaksguide. It contain verrrrrrrry detail explanation of graphic process. But who can read 12 page of nothing but text really? So here its more simple explanation so you can continue play your games.

Process

1) when u click the game icon, the OS will find the game executable file and lauch it. 
Analogous to finding stuff in the main store house. What happen if the the storehouse worker is slow and lazy? It will take a long time to find the stuff you r looking for. This is why the faster the hard disk, the faster OS and game will load.

What happen if stuff/ boxes in storehouse is not place properly?, just toss it around. You'll have a hard time finding the right box. That why we need to defrag the hard disk


2) the game data is placed in RAM. RAM act as a temporary store house because it is much much faster than hard disk. From here, CPU will process the data. Before CPU  process the data, it will store it in  L1, L2 or L3 cache.

3)Now the CPU cannot process all the information. Graphic information will be passed to the graphic card.

Analogy: The CEO at the headquarter (CPU) make strategic plan of the company, but it is the worker and machine in factory (graphic card) that actually make the product.





4)Sometimes finished product is not ship directly to the retailer, it will be stored in factory store room. This is the graphic card RAM, or VRAM.  This is rough and not completely acurate analogy,for more info go to the tweak guide, frame buffer. To supply the showroom with constant flow of product, the factory will produced at greater rate than the actual product flow out rate (Double or Triple Buffer). To be able to do this,store room(VRAM) is need. When showroom (monitor) need to replenish, the product will always be available.

5) the finished product is sent to the showroom, where the product is displayed and sold.


------------------------------------------------------------------------------------------------------------------
Now can you see from the analogies, in order to have high performance gaming machine, u need matching hardware. What is the use of having huge store room (VRAM or RAM) if the factory cannot actually make the product.

Similarly the RAM only act as a temporary store room. Let say the OS required 2GB,  for optimum performance the game use another 2GB and all background process & program use total of 1 GB. So you need 5GB RAM. Adding more ram wouldn't improve you game performance at all.

It is just like building extra storehouse without actually improving the factory manufacturing capability. 

What happen if you have high perfomance graphic card, lots of RAM but slow processor? It will create a choke point, slowing down the overall pc perfomance. It like having state of the art factory, superb worker but of the  CEO company is incompetent, he tell the factory manager to make wrong adjustment.



Adios
