Does anyone find MyBSH registration difficult?

Mussel — Sat, 01 Feb 2020 21:51:53 +0800

I don't know if I go to the correct page, https://bsh.hasil.gov.my/LogMasuk.aspx

It asks for two security question (Bandar mana anda tinggal, nombor telefon didaftar). Then suddenly I have to key in new PIN number, set a total of 5 new security questions (like your favorite color, your favorite song, etc). Not just that, it asks for me to key-in complex password (must have uppercase + lowercase + symbol + number, and at least 8 chars), ok, so I chose a complex password fulfilled all the requirement, then it says password too weak. So I have to key-in a more complex password....... It is so weird.....now I forgot the complex password that I typed already....

Anyone find MyBSH (for renew) registration difficult?

Building a simple filesystem

Mussel — Mon, 27 Jan 2020 11:37:48 +0800

You see, ISO has its file system, ZIP has its file system, and of course we have plenty of other file system like FAT, FAT32, NTFS....etc.

I am thinking it will be fun to create a simple filesystem.

It might be consists of : "Table of Content" (e.g. file allocation table), and the file storage.
Then I will be encountering issues like filename 8.3 or longer names......sub-directory.....

Before I understand FAT, I didn't know that Moving files within the same drive is faster than Copying files.
It is because moving file just change the location in "table of content", without physically moving the file itself....

Is anyone interested?

Turns your existing System for use with VM

Mussel — Mon, 27 Jan 2020 05:38:14 +0800

This tutorial will explain briefly how to turn the physical disk of your computer system into virtual hard disk for use with virtual machine.

If you don't have a VM or cannot afford one, why not try download free open-source Oracle VM VirtualBox.
https://www.virtualbox.org/wiki/Downloads

And you'll need this handy tool from SysInternals, acquired by Microsoft many years ago.
https://docs.microsoft.com/en-my/sysinterna...nloads/disk2vhd

After you start the Disk2vhd.exe, please untick "Use VHDX" if you plan to use it along with VirtualBox.
According to VirtualBox official website, VHDX is read-only, so only VHD can be written and can be supported by VirtualBox.

Please note that the used space of your system's hard disk cannot be more than 127GB, as the output VHD cannot be larger than 127GB (EDIT: only if you plan to use it for Virtual PC).

Then after you install VirtualBox, please create a new instance, specify the OS of which you ran the Disk2vhd. Next, attach the virtual hard disk (.vhd) by browsing the folder of Disk2Vhd (usually the virtual hard disk filename is your <computer name>.vhd)

If you happen to receive "Fatal: No bootable medium found" and your captured system is Windows 10 (I am using Windows 10, so I can only tell from my experience of this particular edition of Windows only), please go to VM System settings, and tick "Enable EFI". Start the instance and it should boot properly.

Please post reply if you have any question that I can answer to my knowledge.
I do hope this save you plenty of time searching for solution / answer.

The mind that travels in space

Mussel — Mon, 27 Jan 2020 02:05:18 +0800

The universe is so huge, but so is our thoughts.

For example, I can imagine that I see distant stars and moon in my head. Does that mean "something" (e.g. particle) actually travelled in space to these stars and the moon?

Can anyone help to clarify my assumption?

How to find a char quickly from very long string?

Mussel — Thu, 19 Dec 2019 03:57:56 +0800

The following is a dummy data I created myself with 619,315,200 bytes (590MB) of "0", and there is only one other character, that is "1", at 426,323,678th file position.

I tried adopt a byte-to-byte text file reading, to look for that only character "1", but it still took me about 30 seconds on my Celeron 1.6GHz CPU.

Is there any faster way?

What's your experience about stackoverflow.com?

Mussel — Tue, 17 Dec 2019 14:04:03 +0800

I just joined it two days ago, posted two answers and one question, and have got two upvotes for answers, and one downvote for question.

Exchanging comments on stackoverflow.com, and seeing how others solve and post their code, only I know that my skill is far from being competent.
I am talking about mostly "binary", "bit-manipulation", "algorithm", "compression" and "encoding".

Compress is not all about LZW, gz, LHARC, RLE, bzip2, deflate. For example, a senior member taught me there are "Kolmogorov complexity" and "pigeonhole Principle" related to compression theory.

Then, there is O(N) or time-complexity...... I am not sure I hear this term back in my IT college days, but time-complexity is frequently mentioned here and there.

Even when talking about bit-manipulation, as a coder who is familiar with SHL, SHR, ROL, ROR, XOR, OR, AND, NOT...and bit masking... There are still some question that make me ponder, which I can't remember the equation.

So, what's everybody's experience on stackoverflow.com? Are you a Scholar(ask question and receive answer) or Teacher (answer question)?

Compress 192-byte string of "A"& "B" as 16 bytes

Mussel — Sun, 15 Dec 2019 20:12:22 +0800

96-bit + 96-bit = 128-bit decimal.

If I have 192-byte string of two distinct characters, it would be considered a great savings by converting it to two pairs of 96-bit number and add it as 128-bit number, instead of 192-bit number.

But how do I decode the 128-bit number (16 bytes data values) back to 192-bit number (without making the compressed size larger than 192-bit)?

Problem: Saving The Universe Again

Mussel — Fri, 13 Dec 2019 20:11:11 +0800

Let see how is the question in Code Jam (Google's highest ranking coding competition?) looks like. I want to try this Problem.

If anyone want to join, please login to codingcompetitions.withgoogle.com with your Google credentials and navigate to "Code Jam 2018 Qualification Round 2018, 1st Problem - Saving the Universe again" and submit your code.

Paste your code here, too!

As far as I see, no Malaysian ranked in the top 50 on this Problem set. From the top 50, I can see mostly from US, and if Asians, they are Japanese, China nationals, Taiwanese, Korean and Indian. Looks like there were over 24,000 participants in the Code Jam 2018 qualification round .

Problem

An alien robot is threatening the universe, using a beam that will destroy all algorithms knowledge. We have to stop it!
Fortunately, we understand how the robot works. It starts off with a beam with a strength of 1, and it will run a program that is a series of instructions, which will be executed one at a time, in left to right order. Each instruction is of one of the following two types:
C (for "charge"): Double the beam's strength.
S (for "shoot"): Shoot the beam, doing damage equal to the beam's current strength.

For example, if the robot's program is SCCSSC, the robot will do the following when the program runs:
Shoot the beam, doing 1 damage.
Charge the beam, doubling the beam's strength to 2.
Charge the beam, doubling the beam's strength to 4.
Shoot the beam, doing 4 damage.
Shoot the beam, doing 4 damage.
Charge the beam, increasing the beam's strength to 8.
In that case, the program would do a total of 9 damage.

The universe's top algorithmists have developed a shield that can withstand a maximum total of D damage. But the robot's current program might do more damage than that when it runs.
The President of the Universe has volunteered to fly into space to hack the robot's program before the robot runs it. The only way the President can hack (without the robot noticing) is by swapping two adjacent instructions. For example, the President could hack the above program once by swapping the third and fourth instructions to make it SCSCSC. This would reduce the total damage to 7. Then, for example, the president could hack the program again to make it SCSSCC, reducing the damage to 5, and so on.
To prevent the robot from getting too suspicious, the President does not want to hack too many times. What is this smallest possible number of hacks which will ensure that the program does no more than D total damage, if it is possible to do so?

Input

The first line of the input gives the number of test cases, T. T test cases follow. Each consists of one line containing an integer D and a string P: the maximum total damage our shield can withstand, and the robot's program.

Output

For each test case, output one line containing Case #x: y, where x is the test case number (starting from 1) and y is either the minimum number of hacks needed to accomplish the goal, or IMPOSSIBLE if it is not possible.

Limits

1 ≤ T ≤ 100.
1 ≤ D ≤ 10^9.
2 ≤ length of P ≤ 30.
Every character in P is either C or S.
Time limit: 20 seconds per test set.
Memory limit: 1GB.
Test set 1 (Visible)
The robot's program contains either zero or one C characters.
Test set 2 (Hidden)
No additional restrictions to the Limits section.

Sample

Input

6
1 CS
2 CS
1 SS
6 SCCSSC
2 CC
3 CSCSS

Output

Case #1: 1
Case #2: 0
Case #3: IMPOSSIBLE
Case #4: 2
Case #5: 0
Case #6: 5

Note that the last three sample cases would not appear in test set 1.
In Sample Case #1, the President can swap the two instructions to reduce the total damage to 1, which the shield can withstand.
In Sample Case #2, the President does not need to hack the program at all, since the shield can already withstand the 2 total damage it will cause.
In Sample Case #3, the program will do more damage than the shield can withstand, and hacking will do nothing to change this. The universe is doomed.
Sample Case #4 uses the program described in the problem statement. The statement demonstrates one way to reduce the total damage to 5 using two hacks. It is not possible to reduce the damage to 6 or less by using only one hack; remember that the President can only swap adjacent instructions.
In Sample Case #5, the robot will never shoot, and so it will never do any damage. No hacking is required.
In Sample Case #6, five hacks are required. Notice that even if two hacks swap the instructions at the same two positions, they still count as separate hacks.

Convert binary string to binary number &vice versa

Mussel — Tue, 10 Dec 2019 22:58:40 +0800

This code snippet would convert long binary string (e.g. "000111") to binary number (e.g. 7). If the binary string is longer than 32 characters of "0" and "1", the binary numbers will be stored in multiple set of 32-bit integer, starting from rightmost bit (LSB).

Maybe someone will find it useful one day.

Let say input is 11111111, what is your minimum number of button presses to reach a number with all even digits?

QUOTE

Problem

Supervin has a unique calculator. This calculator only has a display, a plus button, and a minus button. Currently, the integer N is displayed on the calculator display.
Pressing the plus button increases the current number displayed on the calculator display by 1. Similarly, pressing the minus button decreases the current number displayed on the calculator display by 1. The calculator does not display any leading zeros. For example, if 100 is displayed on the calculator display, pressing the minus button once will cause the calculator to display 99.
Supervin does not like odd digits, because he thinks they are "odd". Therefore, he wants to display an integer with only even digits in its decimal representation, using only the calculator buttons. Since the calculator is a bit old and the buttons are hard to press, he wants to use a minimal number of button presses.
Please help Supervin to determine the minimum number of button presses to make the calculator display an integer with no odd digits.

Input

The first line of the input gives the number of test cases, T. T test cases follow. Each begins with one line containing an integer N: the integer initially displayed on Supervin's calculator.

Output

For each test case, output one line containing Case #x: y, where x is the test case number (starting from 1) and y is the minimum number of button presses, as described above.

Limits

1 ≤ T ≤ 100.
Time limit: 20 seconds per test set.
Memory limit: 1GB.

Small dataset (Test set 1 - Visible)
1 ≤ N ≤ 10^5.

Large dataset (Test set 2 - Hidden)
1 ≤ N ≤ 10^16.

Sample

Input

4
42
11
1
2018

Output

Case #1: 0
Case #2: 3
Case #3: 1
Case #4: 2

In Sample Case #1, the integer initially displayed on the calculator has no odd digits, so no button presses are needed.
In Sample Case #2, pressing the minus button three times will cause the calculator to display 8. There is no way to satisfy the requirements with fewer than three button presses.
In Sample Case #3, either pressing the minus button once (causing the calculator to display 0) or pressing the plus button once will cause the calculator to display an integer without an odd digit.
In Sample Case #4, pressing the plus button twice will cause the calculator to display 2020. There is no way to satisfy the requirements with fewer than two button presses.

How do I setup forum on my PC?

Mussel — Sat, 23 Nov 2019 19:38:22 +0800

Yes, you heard it right. Can I setup forum on my PC?

I'll need to keep my PC awake 24/7 with limited uptime. As an alternative choice because I don't have enough money to renew web hosting and domain name every year.

Question for you: (Please spend time to answer if you could

1. Can I use IIS for PHP-based forum software? If not, what web server do you recommend?

2. Must I have public IP to make my forum available on the Internet?

While I have experience setting up several forum software (Discourse, Discuz!) using web hosting package, I have limited knowledge in doing the same with my own (Windows 10 Home) PC.

Your explanation is highly appreciated!

Planning to deliver goods in K.L. as freelancer

Mussel — Sat, 16 Nov 2019 05:41:00 +0800

Hi all, before I start placing ad on service noticeboard, I'd like to hear your advice.

Is it legal to collect payment for assisting in movement of goods as freelancer?

Here's my plan:
- Deliver goods/parcels on ad-hoc basis using motorcycle
- Cover area in Klang Valley
- Price at least RM30 per trip
- Can issue/e-mail printed official receipt to customer

The price is going to be more expensive than courier express because I am travelling to collection point and drop-off point myself.

Any thoughts?

It needs courage to admit shortcomings

Mussel — Sun, 20 Oct 2019 19:56:48 +0800

It doesn't need courage to boost ego. But it needs multiplies of courage to admit character flaw and shortcomings.

I am a warrior when comes to job employment, have had job hopping for more than 20 companies in the past 20 years. Yes, I was a proud low-level coder 20 years ago competing with Europeans. See, it is very easy to have bloated ego.

But I am a total failure when trying to admit my false pride and weaknesses.

I have, however, admit it in a smaller social circle, definitely not on lowyat.net.

It needs courage to admit shortcomings. Do you agree?

Honda EX5 FI 110cc

Mussel — Sat, 19 Oct 2019 23:54:31 +0800

Sorry, I am new to this subforum!
Anyone with this 30th anniversary (2017) Honda EX5?

So far I have only met 2 identical bikes (1 x silver, 1 x red). I love this bike so much.

My friend wants to find Honda EX5 second hand, but I asked the motorshop I used to visit, and the person in charge said it is hard to find EX5 2nd hand bikes. How is it so?

BTW, CityLink delivery rider also using this model of bikes right?
