Cherry Blossom at Malvern College Tokyo
Starting in early March we set up a camera to take a photo every hour in the hope that we would catch the oncoming cherry blossom. Check it out!

So, we designed and created a prototype hydroponics system in class. Check out the timelapse video we made! Unfortunately, we had some technical issues so it does jump around a little. We will do better next time!

Hi
Hi
My answer to the question: White in RGB is (255, 255, 255) and Black is (0, 0, 0) if we take the average we get 1 for white and 0 for black
i love this dude, he posts very specific and unique content, and he explains it perfectly, thank you <3
I appreciate that!
I couldn't figure out why 0 for black and 1 for white ...please explain
It is because black is the absence of colour, hence 0.
Thank you That was very straightforward and clear. I wanted to ask why 3 bits is not 9, but 4 bits is 16. All number but 3 are raised to the power of 2. Is that correct?
Indexing starts from zero i.e. for 4 bits: 1*2^0 + 1*2^1 + 1*2*2 + 1*2^3 = 15 In binary: 1111 We take 2 to the power of the digit we’re talking about (starting from zero). The 1’s represent 4 “1” boys if you will.
Thank you for the feedback. The reason why 3 bits is not 9 is that it is not 3^2 but 2^3, so not 9 but 8.
Also how may I create a file from scratch? (C++)
Just one question. The positions: Is 0,0 at top or bottom?
At the left top corner
In math it's on the bottom left, but most of the time in computers it's the top left.
Nice help
the reason white is 1 and black is 0 is because pixels are normally lights, so when white is displayed the light is lit, but is not lit when the colour black is displayed
thank you !! very nice video !! what is the software you are using to write python ?
In this video, I am using Replit.
@@CSTeacher thank you so much!!
thank you, that was helpful ♥
You're so welcome!
Wow...! Quite informative. Please add more videos on computer fundamentals and organisation
I will, thank you for the positive feedback.
Very nice introduction to computer fundamentals
Thank you very much for the positive feedback.
i cant get it to work :(
Sir at 2:12 isn't the radius 2?
The radius is 4 because the line stretches from one point of the circle to rhe centre of the circle so therefore it's the radius. The diameter is 8cm
Tysm! I was using this in combination with tkinter. I wanted Python to read a settings file and use the output from certain lines as color values for the bg= and fg=. When I run the code I get an error saying unknown color name "black". It seems the only reason tkinter isn't recognizing the color value is because it's in double quoted strings. Any way to change this?
THANK U SOO MUCH MAN U ARE ARE A LEGEND!! First time i feel that logic gates are easyyy
Thx man 👍
Best video ever 💦💤💨💨💦 +1sub
Yo you nice bro 👏 👌
Hello can I ask a question,, what if the first gate is NOT is it gonna be converted before entering the next gate? For example A is NOT 1 AND B is 1 if the value will enter NOT gate is it gonna be inverted? Before proceeding?
Awesome explanation. Keep it up
Thanks a lot
👍
GREAT STUFF FOR MY PROJECT SAYANG AWAK
Can you please solve the truth table for this
wow, it is one the best way to understand some of the toughest topic.. Thanks you sir
So nice of you
i watch so many videos on this and no one can explain it simpily except this guy, thanks so much saved me
Glad it helped!
great content
Thank you for the feedback, most appreciated.
ik its been a while but id love if u can respond, it doesnt really make sense when solving the truthtables for this because we have 2 Fs now?
But you don't have to use the letter F for the new column. You could pick any letter that you like to represent the output at that part of the circuit. Does that make sense?
@@CSTeacher I guess, thank you. I got the hang of it now. Also respect, been years yet you still respond.
Can JavaScript be used as a programming language?
Yes, you can use JavaScript for your CS IA. In fact, I have supervised several excellent JavaScript projects. Remember though, the most important thing is that you pick the most appropriate programming language for the solution you are going to create.
If i dont have the value of the radius, and i only have the width and length of the rectangle how could i solve it?
You may not have the value of the radius but you do have the diameter. The width of the rectangle is the same as the diameter of the circle. Good luck!
Very informative, glad I landed on this video!!!
Glad it was helpful!
thank u so much its very usefull
You are most welcome
This helps thx
