Angular.js is a Javascript library that connects HTML and JavaScript, like jQuery. Angular has these neat things called expressions. Let’s say this was my JavaScript: var test = “test”; To print that out on the page, you use an expression in your index.html that looks like this: {{test}} When your page loads, it would display the contents of the test variable. There is something called two-way data binding. When a variable inside an expression changes, so doeswhat the expression prints to the screen. Angular is a very nice library. Next post in Code Week is Twitter Bootstrap.
jQuery is a JavaScript library that allows interaction with the HTML and CSS. Every good site uses jQuery, espcially ones that use buttons and animation. Let’s say when you click this , some content would slide out. The jQuery code would look like this:$(document).ready(function(){
$('button').on('click',function(){
$(this).append('Some Text');
});
});
What happens is this: When the HTML code is ready, watch for the event of clicking the button. When that event happens, add some text. It is a lot quicker than using Angular or something else.
Horrible Histories is a British book and TV series. The motto is “History with the horrible bits left in!”. It goes from the Awful Egyptians to the Woeful Second World War, with specials like 20th Century. I have Smashing Saxons, Vile Victorians, Terrible Tudors, Terrifying Tudors, Slimy Stuarts, Rotten Romans, Scotland, London, Stratford-Upon-Avon, 20th Century, Frightful First World War, and Woeful Second World War. I have even seen the Barmy Britain West End play. There is a magazine, which you can subscribe to on the site. You can find the TV series on YouTube.
The Tube Challenge is a challenge where you have to visit every tube stop in London. The record is 16 hours and 29 minutes. The winning route started at Chesham and ended at Heathrow Terminal 5. If I can do it, then I am the youngest person to do it. If I can break the record, then I will have two Guiness World Records. Of course, it will take nonstop planning, memorizing timetables, and luck. I hope to do it on Halloween.
The computer keyboard is very simple. You push a key, and it puts a letter on the screen. But how does it work? When you push a key, the metal part connects 2 wires which allows a current to flow to the computer. The computer measures the voltage and transforms the amount of volts in to binary. The computer compiler reads the binary, and a letter appears on a screen. Very simple.
Once in New York, my lamp shade was tilted against the light bulb. I didn’t notice it at first, but it burned a hole through my lampshade! And if you think that’s hot, a halogen light burned my sock last night! Yikes! My dad once threw a wet rag at a halogen light bulb, in 1 second it dried, then it burst in to flames. Never touch a light bulb when it is on! LED lights are safer.
Two days ago I went to Liverpool in England. It was very cool! After I took a train from London Euston, I stayed at a very nice hotel at 30 James Street. On the first day, I stayed at the hotel the whole day and ate dinner at Gusto on the Albert Dock. The second day, I got on a tour bus, and took it to the Albert Dock and I did the Big Wheel and then I took the tour bus to the World Museum, which was fun. Then I walked to the Cavern Pub and had lunch there. Then I took the bus to the Philharmonic bar and got a hot chocolate. Then I walked to Lime Street station and got my train back to London. Liverpool is very fun. You should definitely go!
Last night I saw the Charlie and the Chocolate Factory musical with my grandmother. It was by Covent Garden, so I got dinner and some sweets. Then I went to the Royal Drury Lane Theatre and saw the show. The special effects were amazing, and the songs were great. There was free ice cream in the intermission. And I got a seat in the Royal Circle! It was a great play! You should see it if you are in London.
Today I went to Windsor Castle in England. I first took the Tube to Paddington, got a train to Slough, and took another train to Windsor and Eton Central rail station. Then I walked to the castle. I walked around the center of the castle and I went to the North Terrace and saw the Doll House, which was pretty overrated and it was not worth the queue. I went to the apartments first, which was really cool and nice. The audio tours were great, so definitely get those. Windsor Castle is very big, but lots of it is closed. It took me about 2 hours. You should go one day!
Today I went to Kew Gardens in Surrey,London with my grandparents. When I got there, I went to the Xstrata and Rhizotron Treetop Walk. It was very scary! Then I started walking towards Queen Mary’s Cottage. But my sister started complaining she was hungry, so I had to walk back to the Cafe at Victoria Gate. Then I went to the huge glasshouse and saw the plants and the marine exhibit. Then I walked up to the Log Trail. I got stuck in the rain for a short time, but I got there in the end. Then I walked to the Pagoda. Then I left. You should go to Kew Gardens!
That is the song I want to learn to play. It is also called Black Key due to the Gb major key signature. It is very fast and the R.H. is hard to play. It will take me about 2 months to learn.
Here is a science experiment on the behaviour of humans:
1. Hide a loved possesion from a sibling. Note their reactions when they realize they can’t find it. Rate how afraid you think they are from 1 being taking it calmly and 10 being fainting. If their reaction is less than five, try a different possesion.
2. Ask them what their missing possesion does for them. Write what they say down.
3. Wait five days. Note their level of fear every day.
4. After a period of five days, give the possesion back to them. Note their reactions.
5. Now chart it all together. Calculate the average rate of change of the fear level over the days. Write what the possesion means to them. If the average rate of change is negative, then your sibling doesn’t depend on his/her possesion. If the AROC is positive, then your sibling depends on that object to feel good.
WARNING:DO NOT tell your sibling what you are doing.
