One day, ex sees x2 running down the street in a panic.

"What’s wrong?" asks ex.

"There’s a Differential Operator in town!" yells x2. “If I run into him too many times, I’ll disappear!”

"Don’t worry," responds ex. “I’ll go have a chat with him. No, don’t worry about me- he can’t hurt me. After all, I’m ex.”

So ex walks down the street to the Differential Operator.

"My friend tells me you’re a Differential Operator," ex says pompously. “Well, I’m ex.”

"Pleased to meet you, ex,” says the Differential Operator. “I’m d/dt.”

Why do programmers always mix up Halloween and Christmas?
Because Oct 31 equals Dec 25.

A programmer is walking along a beach and finds a lamp.  He rubs the lamp, and a genie appears.  “I am the most powerful genie in the world.  I can grant you any wish, but only one wish.”

The programmer pulls out a map, points to it and says, “I’d want peace in the Middle East.”

The genie responds, “Gee, I don’t know.  Those people have been fighting for millenia.  I can do just about anything, but this is likely beyond my limits.”

The programmer then says, “Well, I am a programmer, and my programs have lots of users.  Please make all my users satisfied with my software and let them ask for sensible changes.”

At which point the genie responds, “Um, let me see that map again.”

All programmers are playwrights, and all computers are lousy actors.

Top 10 Things Every Software Engineer Should Know



fuckyeahfluiddynamics:

A thin spout of water is drawn up through a layer of oil in the photo on the right. This simple version of the selective withdrawal experiment is illustrated in Figure A, in which a layer of viscous oil floats above a layer of water. A tube introduced in the oil sucks fluid upward. At low flow rates, only the oil will be drawn into the tube, but as the flow rate increases (or the tube’s height above the water decreases), a tiny thread of water will be pulled upward as well. The viscous outer fluid helps suppress instabilities that might break up the inner fluid, and their relative viscosities determine the thickness of the initial spout. In this example, the oil is 195 times more viscous than the water. (Photo credit: I. Cohen et al.)

Computer Science Resources Masterpost

meghabits:

I’ve been getting some questions about where to learn coding and other related skills online, so here are a bunch of resources for different types of learners! Feel free to add any I may have missed.

Courses and interactive learning:

Codeacademy- Has a few very good starter languages. I’m a big fan of Python for a first language if you’re looking for straight up programming. If you’re looking to learn more web design type stuff rather than programming, try JavaScript first and then move into PHP. They’re all available on Codeacademy

Learn Python - Only teaches Python, but it has a compiler right on the bottom of the webpage, which takes out the sometimes confusing process of setting up to code. The tutorials look top notch and really get you thinking. 

Project Euler - A more technical and math/logic based approach to learning. Confusing to some people and fun for others. 

The Python Challenge - Similar to Project Euler, only with more logic I believe. I didn’t really like it because the problems had too many layers for me to focus easily, but others may find it rewarding. 

MIT Open Courseware Electrical Engineering/Computer Science - A great resource for real MIT course content. Excellent for people who are good at learning in more classic traditional college type environments. You can pick and choose what you want to get started with and even choose more hardware related or software related courses, whatever you want to know!

Udacity - This is one I’ve used more than others. It consists of shorter lecture style videos and interactive problems to solve. I love this personally because I like lecture settings with a more hands on feel. The intro to computer science course teaches Python, which I am a huge fan of.

The New Boston - Great for audio/video oriented learners, with long but productive tutorials. I recommend the beginner Java series if you’re looking at this source.

Tutorials

The official Python Tutorial - This is in the Python documentation, and is sort of the straight from the source tutorial. I’ve never actually gone through it, but have referenced it before and in those cases it was quite handy. 

The Java Tutorials - Same thing as the Python tutorials, this is part of the Java documentation website. I’ve never used it in my life but it may be worth a go!

Books

Operating System Concepts, 8th Edition - A great operating systems book with lots of examples in the C language. I recommend this when you have your feet wet, because C can be very difficult for inexperienced programmers. It’s a low level language with a high level of control, so it can get really confusing if you’re inexperienced.

Introduction to the Theory of Computation - A VERY heavily theoretical book but a good one nonetheless. Lots of discussion about formal logic and languages, turing machines, computability, automata, and more. Good examples and although it’s a really dense read it’s still very good. This is much less coding and more theory. This is another read I wouldn’t start with but is good for experienced people. 

These are just my favorites from my classes at school since I’m not a huge book learner. 

Hope these help!
