Hardening your USB Drive


Assalam...
Last time, the admin posted an article of "Defend your drives from AUTORUN.INF malware" and it is recommended that you read that article first before you proceed to the next paragrapgh...
This article may be a continuous article from the article mentioned in the previous paragraph but it is actually more into "hardening" to "protecting". The following steps require you to use any Linux-based Operating System. The reason is that, Windows OS will NOT allowing you to do this kind of activity hahaha *obviously*. In this tutorial, I will use my favorite Ubuntu (Karmic Koala) OS.

After you have created the "autorun.inf" folder based from the previous "Defend your drives from AUTORUN.INF malware" article, go inside the folder and then
  1. create a folder named "con" and
  2. create a file named "desktop.ini"

Using a text editor (gedit in Ubuntu), simply type in the following parameters inside the "desktop.ini" file:

Or copy and paste it from here...
[.ShellClassInfo]
CLSID={2559a1f2-21d7-11d4-bdaf-00c04f60b9f0}
Save the "desktop.ini" file and close the text editor. Next, go inside the "con" folder and then create a folder name "aux".

Inside the "aux" folder, create another folder named "nul. ", followed by your favourite words with "dot" in within the words. For example, I named the folder as "nul. Bwua.huhwu.hauhwa". Now you are done =) hehe

Oh... Lupa gitau... If you want to create a folder in Ubuntu OS, right click on the blank spaces inside the window and click on "Create Folder"...

Cabut USB drive biskita and pacak arah any Windows OS-based computer... I used my Windows XP to examine the result... As you can see, the folder's icon has been changed to "kunci manga" and try to click on it and see what will happen... The answer is, "nothing" will happen hahahaha... I haven't try this technique on Windows Vista or Windows 7... Let us see if someone actually can access the file from Windows OS other than Windows XP else it would be still prone to autorun.inf malware (malicious software) attack...

Hopefully that would give benificial to all of us and help you to minimise your USB drive especiallypengdrive from being infected by other machines...

Sekian, sampai jumpa lagi~

Wassalam.

The Lasso Tool

Assalamualaikum,
After a while of not posting on anak.it I've decided to go with a very basic tutorial that a friend of mine has requested recently, which is how to lasso an object, person and so on.  One thing I know about lasso-ing to complete "perfection" is that you need patience and a good eye.
To start off, I've picked this picture of fellow member Fadhullah as an example.

Second step, on the left side you will see a column of tools, look for the Lasso Tool icon as circled above, right click on the icon and left click on "magnetic lasso tool".
Third step, left click on the image where you want to start and just circle around that object/person, make sure to have both ends meet or just double click to join the ends. The selected area will be represented by "marching ants". You can try to make it as perfect as you can, but if it doesn't turn out the way you want it to, don't panic, I'll tell you how to fix it.
Fourth step, like the image above, if you have accidentally lasso-ed a part of the image that you don't want to lasso simply hold down the alt key and left click on your mouse, release the alt key and move your mouse to "throw away" the unwanted parts. Make sure to have both ends meet or double click.
Fifth step, just like the fourth step, you can do the same alt + left click to take away the image in between, say, the arms to create a gap.
Sixth step, in cases where you want to select the part of the image that you accidentally left out, you can just hold the shift key + left click and go over the area that you missed. This is especially essential when it comes to parts of hair that sticks out.
To lasso the "exact" part of the image that you want, make sure to zoom into or out of the image by pressing ctrl together with the + or - signs so it can be as precise as you want it to be. Be prepared for sore eyes.
This is basically the end result of the lasso-ing of Fadhullah's image that I've done. If you want to select the reverse of what you have lasso-ed just press ctrl + shift + i, you can add effects to the background or just simply delete it by pressing the delete button. That's pretty much all I have for now on the Lasso Tool. Hope this was helpful.
For this post, I will show you an easy way to colourise a black and white brush like the image below

First thing you’ve got to do is pick a brush of choice, for my example I’ve chosen this brush from here. When you’ve thought of what brush you want to use you should always create a new layer before you start pasting the brush so you can just easily delete it if you ever change your mind. To do so, you should click the new layer icon in the lower part of the layer’s section like so,
Layer 1 will pop up in the layer column and you can then paste the brush there. After pasting the brush of choice you can now begin selecting colours. Again, this is essential for you to
1. create a new layer, you can name this layer by the name of the colour, like such
2. Make sure you change your brush to basic brush through the icon circled and numbered (2.)
3. Colour over the part of the image that you want to be colour like in (3.) then change the blending mode from Normal to Soft light or overlay, but in my opinion it’s better to just use soft light. (This can be found in the Layers’ column next to opacity in case you didn’t know).
You can then repeat this process of colouring to the other parts of the image with different colours. Take note that you should ALWAYS create a new layer because if you use the same layer with different colours you might end up with deleting the whole colouring when you just want to remove a single colour in the end. But then ctrl+alt+Z can be used too but that would be of limited use as the history won’t fully be there. This is basically what I’ve done to the brush
And this is the result when I apply the soft light blending mode to the colours,

Notice that the headphone isn’t coloured, that’s because super black images can’t be coloured. You can try though, but I won’t really pop-out as much as the rest of the image. Anyway, I hope this tutorial was helpful. Again, for more inquiries, please go to the “Miana Kan Tue?” section above.
Experiment, experiment, experiment.

The Importance of Doing Research


Assalam...
Last time I was doing a research on Brunei's history and came across the following image:

I was wondering... "how come?"... If you are given a task to design or draw a specific image, make sure you at least do a little research or else the result might turn out to be just like in the picture above...
Just to share it with biskita untuk sama-sama memikirkannya... Sekian..

Basic Print Screen Trick


Salam Anak IT.
"Print Screen" key on my keyboard

How many of you treat the "Print Screen" key on your keyboard as a friend? Those who are doing assignments on "System's User Manual" will most probably familiar with this feature. Last time when I checked someone's system documentation from the technical college, I found out that there are people who always use the Print Screen key but are not doing it properly. What they always do is that simply paste the whole thing in a word processor that they are working on (such as MS Word) and then CROP the image... As results, there are "extra" irrelevant bitmap pixels on every edges of the image.
For example, I want to get the screenshot of one specific window. When I press "Print Screen" key alone, it will give me like the following image:

You do not have to worry if it is a little bit "weird" for you since I am using 2 monitor screens extended but yes, the "Print Screen" key did capture the whole screen... I only want to capture the PDF Reader's window with the "BRUNEI DARUSSALAM" wording in it... How am I going to do that?... Is that even possible?...
The "key" of making it possible is the "Alternate" key or also known as "Alt" key.
"Alt" key on my keyboard

Try to combine the "ALT" key with the "Print Screen" key and paste the clipboard item into any image processing applications (Adobe Photoshop, GIMP, MS Paint etc.) and see what will appear. Make sure that the targeted window is "active" in a way that it is "selected"? Hahaha lebih kurang miatu la...
The expected result

Try to experiment other combination of key as well such as CTRL key or even SHIFT key and examine the result for your own knowledge and skill.
That is it for today. If you have any doubts or questions to ask, let me know through this online form.
~ Terima kasih daun keladi, ada idea jumpa lagi ~

Using External StyleSheet

I'm assuming if you are reading this tutorial, you already know what Cascading Stylesheet (CSS) is. If you don't, you should head here first.

External stylesheet gives an advantage over inline stylesheet (that is having the stylesheet inside the HTML: it reduces the page load time since the CSS is all inside one file. Moreover, the changes made on that one file are simultaneously reflected on all pages that link to the stylesheet.

So, how do we go about using external stylesheet?

Step 1:

First of all, you will need to have all your CSS codes saved into a file. You can name the file anything you want but be sure to save it as .css extension. Meaning, if you name your stylesheet 'style', the full filename is 'style.css'.

Step 2: 

Upload this file to your server. Take note of the directory where you upload the stylesheet. Usually it is stored in the root directory.

Step 3:

Next, open up your HTML file and stick this line between your tags:



However, if you are storing the stylesheet in a specific folder (not in root directory), for example in a folder called styling, the code will look like this:



Now you may want to know what purpose does the code above serves. The code above is used to call or load up the stylesheet into your HTML.

Step 4:

Save your HTML file (and upload it to your server if you haven't) and you're done!

My Personal Alarm Clock


Salam Anak IT.
Today I would like to share my software-based personal alarm clock that I created using simple Visual Basic 6 coding. It was built for my personal purpose but now I just feel like I want to share it with Anak IT Readers... You may download the zip file (consists of the program and MP3 file) here. Here we go...
Facts and Features:
  • Created in 2007 using Visual Basic 6
  • The program size is only about 100kb
  • It uses Alarm.mp3 file for the "alarm" sound
  • Works well with large speaker
  • Of course it needs a speaker... Hahahaha
  • Bebunyi pada tiap-tiap pukul 7 pagi
  • Using 2 ways of "Custom Alarm Time"; Specific Hour-Minute-Second and Hour Selection (From 1am till 12pm)
Cara penggunaan (Specific Hour-Minute-Second):
  1. Taip waktu yang biskita inginkan di dalam format "Jam:Menit:Saat"
  2. Tekan butang "Add" or simply press Enter key on your keyboard
  3. By using this method, the ring will only last about 60seconds+
You will realise that the "Nill" has changed to your requested time, in the following example, it is written as "21:35:00"
Just wait for the time and it will ring the Alarm.mp3 at the time specified. You may use any other MP3 file such as your favourite song or HEAVY METAL SONG supaya tebangun slajur when it rings hahahaha but remember to place your MP3 file in the same folder where the program resides and rename the MP3 file into "Alarm.mp3" with capital A.
Cara penggunaan (Hour Selection):
  1. Simply select the hour and let it be~
  2. Baca doa sebelum tidur
  3. This method WILL NOT STOP THE RING unless you close the program or buang speaker biskita ke sungai (which is good for those yang "tidur mati" hahaha)
Simple? Huhuhu maybe the program is not as "user-friendly" as you expected it to be but it was created for my own personal usage in the first place...
Some useful tips:
  • Jauhkan speaker dari tempat tidur
  • Pasang volume speaker basar-basar biar hingar
  • Taruh gam plastik arah volume speaker so it will FORCE you to "betukang-tukang" membuka balik the tape (where by that time you will be more than awake hahaha)
  • Mun kan mau lebih bisai, replace the default MP3 file with MP3 urang membaca azan or simply record your own voice saying "HOIII WANGGG BANGUUUNNN!!!" or something like "Aku banaaa banaaaaa kannnn kauuuuuuu~" or anything you like...

Sekian, harap ianya akan dapat mendatangkan fa'edah kepada kita semua. Wassalam.

First "heyyyyy"

Second "heyyyyy"

Third "heyyyyy"

Reuse - Laptop Cooling Fan


Salam Anak IT.
Last time I posted an article on "Another way to make use your USB Extension Cable". The objective is to re-use any computer parts or computer related thing yang langsung inda lagi bepakai into something more useful. Today I have another "junk" for that.
It is my laptop's Cooling Fan jenis "portable". Since I seldom use my laptop, my cooling fan ampai-ampai tah ganya... So daripadanya ampai-ampai, tantu digunakan in other different way...
We all know that mostly (or maybe semua) cooling fan yang bejual di kadai atue makai USB cable as its power source's channel/medium... So... I was thinking... Is it possible if tane pakai USB device (usually around 5 volts) ke karan dinding (200+ volts)? Inda melatup ka tue if modify the wire then connect ke socket karan dinding? Hahaha obviously SOMETHING bad would happen... So I didn't try that out like I usually did... Then... I was thinking again... Of another alternative...
Tadaaa~ I saw this plug "ampai-ampai" sebalah my printer... So I smiled hahahaha you know what I was thinking... This converter plug is not an ordinary plug... It converts the current's voltage (and other elements which I am not familiar with since I am not an Electrical personnel) into USB's international standard voltage so that any USB devices can have power supply from any ordinary wall plug's current (lurus ka tue? haha).
The result? I used it as a cooling fan for both internet modem and router in the house. Well maybe not as good as "kipas angin" but just enough to ventilate the devices.
Time malam inda belampung. Bisai dijadikan lampung untuk tidur.

P/S : Good luck for those who are having exams especially those yang from UBD, ITB & UNISSA... Exam fever~ =)

Replacing new Thermal Grease


Assalam Anak IT Readers,
Do you have a computer? laptop? If ada, brapa lama dah biskita memakai? Setahun? Dua tahun? Have you ever wonder after a certain period of time, computer biskita mikin skajap hangat rasanya? If yes then you need to read the rest of this article..
Pernah biskita melaha Processor biskita? If yes, apa yang biskita nampak in between the processor sama heat sink processor? Something yang usulnya macam chewing gum? Hahaha well that is what we call Thermal Grease.
What does this thermal grease do is basically untuk menulung "menyiruk" panas dari processor naik ke heat sink yang biasanya disimpan di atas processor. If biskita masih "blur" pasal thermal grease, cuba biskita fahami this site.
So... Masalahnya pasal thermal grease ane, ia dapat jadi karing and MALFUNCTION sudahnya lama-lama hahaha as in ia inda lagi tekarih untuk "menyiruk" panas dari processor naik ke heat sink... Then ia menjadi "blocker" ta plang which is panas atue inda naik ke heat sink and BEPARAM arah processor. This actually same goes to video chip, not only processor. I've heard a lot of stories (especially laptop HP) where the motherboard inda lagi dapat dipakai after 1-2 years. This is because of the video chip "kana salai" oleh heat yang ia sendiri produce...
Then... How to avoid this? For my case, I personally need to check on my processor's condition every 4-5 months. Last time I did a check-up and found that my thermal grease is "inda lagi bermaya" nya urang kitani hahaha so I think it is good to share this with you... I will elaborate further on the pictures below:
This is my heat sink... As you can see, the thermal grease (grey compound) karing udah... So I need to replace it with new thermal grease...

That is my Dual Core Processor... Can you see the thermal past atasnya?

First, remove the current thermal paste from both heat sink and processor (in my case I used minus type screw driver so kira dikikis-kikis sampai licin)

Tadaaa~ hehehe bacilat selajur... And I forgot to take a picture of my processor yang abis bekikis dah...

Then, prepare your Thermal Grease... I used ThermalTake's TG-2 Thermal Grease

This thermal grease can be found arah any kadai computer but biasanya yang bisdia jual atue bukannya jenis "standard" thermal grease... Yang biasa ja... So if you want to buy Thermal Grease, I recommend you to buy any brand from ThermalTake, Cooler Master or even better Arctic Silver (Arctic Silver usually comes with remover as well). Try to look for it arah kadai computer Chong Hok (if na salah la) Kiulap berdepanan dengan C.A Mohammad and sebaris Minuman EasyWay...

Apply the thermal grease on top of your processor (or video chip)

Make sure biskita ratakan the thermal grease. The important point is jangan biskita bagi luan tabal. Nipis is better but jangan jua luan nipis. After you are done, pasang balik the heat sink CAREFULLY and switch on computer biskita seperti biasa.

Oh... Another thing... Jangan lupa buang habuk (dust) rah kawasan berhampiran processor (if rajin clean the entire motherboard). Use a brusher.

There you go... If dapat, try to monitor your cpu's temperature from time to time... You may read this "How to monitor CPU temperature" article...
Sekian, wabillahittaufiq walhidayah, harap maklum.

P/S : This activity requires your concentration and precautions since you are dealing with the "brain" of your computer a.k.a processor. You don't want to spoil the processor and bali baru... Unless harganya 30sen hahahaha ;)
