In Topic: What is the difference between Adobe photoshop and paint ?

03 February 2018 - 11:28 AM

Hi

 

the main difference is that paint is initially designed for bitmap images (working at the pixel level), whereas Photoshop is design to handle photos and can work at different levels (blur filters, saturation, etc.) or also at pixel level (event though it is not its primary purpose).

 

I personally use paint just for one thing. crop images in my clipboard (print screen) before pasting, but even that is easy in a software like photoshop.

 

For all the rest, I use gimp (open source alternative to Photoshop)

Hi

 

to me, the easiest answer is Lubuntu (Light Ubuntu). Easy to install (ubuntu), huge community (ubuntu) and very efficient with old PCs or intel based MACs (light graphical engine and linux based system).

In Topic: New to programming, whats a good first language?

Hi

 

compiled languages are useful for professionals or people caring about performance. Interpreted ones are easier to get into.

 

For you, I would recommend Python 3. This is a interpreted script language very user friendly, very portable, with lots of libraries (graphical, network, scientific calculation, etc.). With it, you can do quite everything you can imagine (desktop or mobile apps, even back-end web servers can use python).

 

however, is you wish to do your own website, you'd rather have to get into (in this order) HTML 5, CSS 3, javascript, jQuery and bootstrap for the front-end, and then, for the back-end, learn about databases (mySQL, etc.) and back-end language (php, Node.JS, etc.) to start with. When you have an idea of all these language can do, you will be able to have fun with your high quality website.

E=mc2 is a formula figured out from the special relativity which is one of the most beautiful discovers of the 20th century. This theory is now accepted as the main framework for all phisics theories like mecanics, electromagnetism, particule physics, etc. Thus, nowadays, if a theory is not relativistic, no theoretical physicist will want to ever think about it.

 

E=mc2 is only the surface of the iceberg, it "just" tells that there is an equivalence between mass and energy, which means that from empty space, a particule can be spontaneusly created provided that enough energy is located in the "same space", leading to quantum fluctuation.

 

Regarding the nuclear bomb, I will just ask a simple question :

Do you think that the first guy who discovered how to make a fire should be ashamed because of flamethrowers
