A 64-year-old Man In Canada Who Was Left Disfigured After A Hunting Accident Has Become The OLDEST Person

A 64-year-old man in Canada who was left disfigured after a hunting accident has become the OLDEST person in the World to receive a FACE Transplant. Four months after the surgery, performed at Hospital Maisonneuve-Rosemont in Montreal, the man has regained the ability to breathe properly and has begun to chew, smell, and speak with his new face.

ETH researchers from the Functional Materials Laboratory have developed a silicone heart that beats almost like a human heart. The soft artificial heart was created from silicone using a 3D-printing, lost-wax casting technique; it weighs 390 grams and has a volume of 679 cm3. They proved that the soft artificial heart fundamentally works and moves in a similar way to a human heart. However, it still has one problem: it currently lasts for about only 3,000 beats, which corresponds to a lifetime of half to three quarters of an hour. After that, the material can no longer withstand the strain.

Know these to get started with Python.

Web Development has advanced over a period of time

Taking a Mobile First Strategy to Web-development

Changing trends in web design via web development

Java's Ongoing Popularity

The Era of Modern Web Development

Python as a first language: a roadmap to getting started.

I personally prefer Java as a first language. Put non-technically, it is a lot less convenient, so you get a more realistic idea of how computers work. Nonetheless, Python is an amazing language (with convenience as one of it’s values) so it makes sense as a gentle introduction. It’s also a popular language for data science and machine learning, so it’s great to have experience with.

The 3 ingredients you need to get started:

The Python Language Interpreter: when you write some code in a text file and save it as a .py file, the Python interpreter is what turns that code into commands that your computer can then actually preform. This is necessary.

An Integrated Development Environment (IDE): An IDE is like a helpful text editor for programming. Some basic features include auto-complete, typo and mistake catching, and automatic text coloring to make some parts of your code easier to find. This is optional but highly recommended.

Some learning resources: We’re going to need something about programming basics, problem solving in computer science, using an API, learning how to use google and stackexchange, data types, control structures, and then maybe an object-oriented programming intro, and eventually all the neat advanced features of the python language. Then we need to learn how to use Numpy (for scientific computing), Pandas (for easy data storage), and Tensorflow (machine learning!). Add some handy cheat-sheets for python, numpy, pandas, and Tensorflow, and we’re good to go.

Other posts will adress download, installation, and resources.

A curriculum:

Like I said up above, we need to know how to do the following. Save this and make it a checklist.

Learn to use google to answer questions about installing or using python, any packages, or computer science.

This also includes getting to know how to search Stackexchange, the website for coding questions n’ stuff.

How to install python 3 and get set up

How to install an IDE like Eclipse (with PyDev), IDLE, or Notebook++.

Programming basics: how does python work? What does the language look like? How does tabbing work?

Understand basic logic, including AND, OR, XOR, NOR, NAND, XNOR, Implies, and If…Else statements.

Variables: what are they, how do I set one and change it?

Basic math in Python.

Data types: what kinds of variables can I have? How does my computer store data? How do I use those types of data? What are the key commands and operations I know how to do?

Control structures: if, else, elif, for loops, while loops, break, continue

Methods! What are they, how do I make one, what can I do with it?

The open() command, the all() command, other neat built-in methods

<function name>= lambda <your variables>: <single line method>

Problem solving in computer science: now do fizbuzz.

What’s a package?

Importing packages, installing packages you don’t have with PIP

Using an API: how do I find one and how do I read it?

object-oriented programming in Python: what’s a class, how do I make one, how do I reference and instantiate one, methods, class vars, etc

Error handling: how to do exceptions

All the neat advanced features of the python language: iterators, generators, list comprehensions, enumerate, range, assert, with…as, etc.

Read through the Numpy API (for scientific computing), data types, matrices, stats, methods, etc. A short detour through scikit would be helpful.

Read through Matplotlib.pyplot API, plotting, plotting options, histograms, scatterplots, etc.

Pandas (for easy data storage), data frames, series, built-in operations on columns and rows, loading from a CSV, saving as a csv, apply, etc

Tensorflow (machine learning!) For basic stuff, shoot for knowing how to use the estimator package, which is discussed elsewhere on this blog. Also get to know the nitty gritty, including tensors, layers, tensorboard, etc.

Blockchain in the Modern Age Education System

Sectors like retail, banking, and healthcare are fast to adopt innovative technologies. However, the education sector is slow in the race when compared to the other areas. The education sector is the best testing ground for emerging technologies. 

Blockchain technology can be the deciding factor on how the future generations are built in terms of skills and awareness.

Worth a read :)

The attack by Chinese spies reached almost 30 U.S. companies, including Amazon and Apple, by compromising America’s technology supply chain, according to extensive interviews with government and corporate sources.

Phew, reading this story was a trip.

Phew, Reading This Story Was A Trip.

TL;DR, this chinese hacker group (successfully) coerced chinese motherboard manufacturing plants into altering the designs for their motherboards to include a tiny chip- no larger than the tip of a pencil- so that they could have control over machines that were later assembled on top of these motherboards further down the supply chain.

Their targets appear to have been large tech corporations (Apple, Amazon were/are affected), as well as positions within the US government/military. Supposedly, no consumer data was stolen or affected.

This thing is so goddamn tiny, and yet it supposedly has the power to alter essentially any instructions that get passed from OS to CPU, as it acts as intermediary in between the RAM and CPU from what I understand. It has network access due to how it’s connected to the baseboard management controller, so it can call home for instructions on what code to run, since… it can do whatever it wants with the cpu, apparently? I’d love to see a more in-depth look into how this technology works, honestly.

Considering this doesn’t seem to affect end users at all, and mostly only has caused harm to large corporations and also the US government/military… my reaction to this is mostly a mixture of “lol” and “holy shit that sounds like something out of a goddamn action movie”.

5 Questions from a Year of Education on the International Space Station

image

This year, we’re celebrating a Year of Education on the Station as astronauts and former teachers Joe Acaba and Ricky Arnold have made the International Space Station their home. While aboard, they have been sharing their love of science, technology, engineering and math, along with their passion for teaching. With the Year of Education on the Station is coming to a close, here are some of the highlights from students speaking to the #TeacherOnBoard from across the country!

Why do you feel it’s important to complete Christa McAuliffe’s lessons?

“The loss of Challenger not only affected a generation of school teachers but also a generation of school children who are now adults.” Ricky’s personal mission was to bring the Challenger Mission full circle and give it a sense of closure by teaching Christa’s Lost Lessons. See some of Christa’s Lost Lessons here.

Have you ever poured water out to see what happens?

The concept of surface tension is very apparent on the space station. Fluids do not spill out, they stick to each other. Cool fact: you can drink your fluids from the palm of your hand if you wanted to! Take a look at this demonstration that talks a little more about tension. 

How does your equipment stay attached to the wall?

The use of bungee cords as well as hook and loop help keep things in place in a microgravity environment. These two items can be found on the space station and on the astronaut’s clothing! Their pants often have hook and loop so they can keep things nearby if they need to be using their hands for something else. 

Did being a teacher provide any advantage to being an astronaut?

Being an effective communicator and having the ability to be adaptable are great skills to have as a teacher and as an astronaut. Joe Acaba has found that these skills have assisted him in his professional development.  

Since you do not use your bones and muscles as often because of microgravity, do you have to exercise? What type can you do?

The exercises that astronauts do aboard the space station help them maintain their bone density and muscle mass. They have access to resistance training through ARED (Advanced Resistive Exercise Device) which is a weight machine and for cardio, there is a bicycle and treadmill available to keep up with their physical activity.
