Draw animated tree in bash

BASH, Linux, Operating System, Program, Ubuntu, Unix Published: December 25, 2016 Last Updated: December 25, 2016 Table of Contents Fork Make A Gif It’s Christmas again and you’ll be receiving all kinds of greetings. How about greeting them back with a fancy way ? Show off your nerdiness with this super cool Christmas Tree in Bash. All you need is a bash shell. Most systems have bash shell by default, so you don’t have to install anything for this ! All thanks goes to the Argentian programmer Sergio Lepore for this cool script. Here’s how it looks : Christmas Tree in Bash Christmas Tree in Bash First of all open a terminal and copy this script to your computer : wget -d -c -O “christmas.sh” “https://raw.githubusercontent.com/sergiolepore/ChristBASHTree/master/tree-EN.sh” Make the file executable : chmod u+x ./christmas.sh RUN ! ./christmas.sh Ain’t that fancy ? All thanks goes to the Argentian programmer Sergio Lepore for this cool trick. Fork You can make your own little changes in the script to add your name and other stuff. I added my name using this line : tput cup $((lin + 3)) $((c – 4)); echo subins2000 I added the above line just after “And lots of CODE in $new_year” line. You can do anything with this script. Maybe translate it your own language or add more fancy stuff. Let me know what you have done Make A Gif Let’s make a gif of this great terminal gift. You can use this gif to send to your friends or post on social networks. We’ll use a screen recorder and a gif converter. For this, install these : sudo apt install gtk-recordmydesktop ffmpeg winff Use gtk-recordmydesktop to record the terminal. This will output a OGV file. Then do the following 2 commands to make the gif : ffmpeg -y -i input.ogv -vf fps=10,scale=800:-1:flags=lanczos,palettegen palette.png ffmpeg -i input.ogv -i palette.png -filter_complex “fps=10,scale=800:-1:flags=lanczos[x];[x][1:v]paletteuse” output.gif If you want to trim the video, you can add the following options to the second command : -ss 3 -t 30 which stands for “start from 3rd second and end at 30th second

Learn microsoft visual studio

Step 1 : Set up your IDE
by Nicole Bruck
Before Installing
Let’s ensure that our machine is ready for us to install Visual Studio 2017. We’re going to need to do some updates and make some room!
✓ Apply the latest Windows updates
✓ Check for sufficient disk space
Download
Now let’s go get our Visual Studio 2017 download so that we can get ready to install!
✓ Download Visual Studio 2017
✓ The file will download and you should “Save As…” if needed
Install
Pick which components you would like to install or use our “default install” to get the most common tools.
✓ Locate the file, right-click and select “Run as administrator”
✓ Click to run
✓ Select “.Net desktop development”
✓ Install and wait until finished
Launch
You’re ready to rock and roll! Feel free to explore or get a head start with our next tutorial: Build an App.
✓ Restart your computer, if required
✓ Launch Visual Studio 2017
✓ Sign in (optional)
✓ Welcome!
Step 2 : Build an App
C# WinForms App
C++ Console Application
ASP.NET Core Web App
Create
We’re going to create an app to display, “Hello, World!”, which we will write in C# and run on Windows, specifically a WPF app.
✓ Create a WPF app named, “HelloWorld”
✓ Open the “Toolbox” and pin
Edit
We’re going to add a text area and button to our app. Then we’ll add an action to our button to display, “Hello, World!”
✓ Add a Button and TextBlock to your MainWindow.
✓ Add an action to the Button
Build & Run
Now we’re going to build the project so we can make sure that all the code works.
✓ Select the start button
✓ Click the button to see the dialogue
Step 3: Debug & More
The Visual Studio debugger helps you observe the run-time behavior of your program and find issues. With the debugger, you can break execution of your program to examine your code, examine and edit variables, view registers, see the instructions created from your source code, and view the memory space used by your application.

Creating drop down bar in html and css

There has always been big differences across how different browsers handle form styling. There probably always will be – because UI design choices aren’t described in the specs. Browser makers perhaps view this as one of the ways they can differentiate the user experience a bit. Select (dropdown) menus are one that is particularly weird.
When I say dropdown menu, I mean:

<select>
  <option>Apples</option>
  <option>Oranges</option>
  <option>Banannas</option>
</select>

Left completely alone by CSS, this will render consistently across browsers. On Macs, 11px Lucida Grande.

#What if you change the font-family?

select {
  font-family: Cursive;
}

WebKit browsers (Safari, Chrome) will ignore you. Firefox, Opera, and IE will respect your change. The font-family won’t cascade into the select though, you have to explicitly declare it on them.

#What if you change the font-size?

select {
  font-size: 32px;
}

This is a fun one. In WebKit, if the font-size is between 0 and 10px, it will render the font size as 10px. From 11px to 15px, it will render as 11px, and 16px or larger it will render it as (wait for it), 14px. This behavior is similar they handle search inputs.
Firefox, Opera, and IE will respect your change but again only if explicitly declared on the select, it will not cascade.

On the left, the reigned in webkit font sizing. On the right, Firefox respecting exactly what its given.

#Can you get WebKit to respect your changes?

Kinda. You can set border: 0; on the selects and it will make it look like a kinda crappy version of a dropdown but still have some UI. It will also allow your font size and style choices to come through.

border: 0; font-family: cursive;

You can also set -webkit-appearance: none; and you’ll get what looks like a rounded corner input box, but still has the interactions of a select (click to reveal menu, keyboard commands, etc). It will also respect your font choices this way.

appearance: none; font-family: fantasy;

I’d say appearance is your best bet for fully custom dropdowns, but it would be WebKit only because while -moz-appearance: none; works it doesn’t remove all the chrome, just some. Opera doesn’t support appearance at all.

#What about the dropdown itself?

As in, the thing that shows the choices when activated. As far as I know, there is no way to style these in any browser. Not even bold or italic. The closest thing to style you can get is grouping them by using . This is probably mostly a UI thing, but it might be a security thing too. You wouldn’t want people doing tricky things with fonts that make it unclear what option is selected.
