Parallel Programming: Multiprocessing in Python

  • If (let’s say) you have a quad-core processor running a program only on one core, you are essentially letting go of the other three cores and hence three times the computation power you are using.
  • First is Matrix Multiplication which can be easily parallelized and next we shall see prefix sum scan, which on the first look seems to be a sequential problem but can be parallelized to run on multiple processors.
  • Theoretically, given four cores should increase the performance of the algorithm by four, however, there are additional overheads when we are trying to run the processes in parallel.
  • For example, we have to spawn multiple processes and to do additional processing as in this case we divided the matrix rows to run on different processors.
  • Calculating scan sequentially is easy enough, we have to maintain a variable for running sum and add every element to it one by one and replace it.

QuickBasic64: Basic for the Modern Era

  • Popular as a beginner programming language in the 80’s and evolving into a powerful professional tool in 90’s, BASIC (and its successor QBasic), helped many people develop a love for programming.
  • Compatible with most QBasic 4.5 code, QB64 adds a number of extensions, such as OpenGL and other modern features, providing the perfect blend of classic and modern program development.

From Mercury to Artemis: The evolution of the spacesuit

  • The Apollo suit was designed for only one mission and it had to be lightweight to allow the astronauts to do work on the moon.
  • In 2017, Boeing unveiled the spacesuit passengers will wear aboard the Starliner spacecraft, a next-generation space capsule that will take people to and from low-Earth orbit, including missions to the International Space Station.
  • NASA shows of its new space suit designs, xEMU, left, and the Orion Crew Survival System suit on Oct. 15, 2019.
  • The Orion suit is designed for a custom fit and incorporates safety technology and mobility features that will help protect astronauts on launch day and during the high-speed return to Earth.
  • The xEMU will allow for greater mobility, especially in the shoulders, and will be able to keep astronauts comfortable from 250 degrees Fahrenheit to minus 250 degrees Fahrenheit, NASA spacesuit designer Amy Ross said during the event.

We need a new field of AI to combat racial bias

  • Most recently, in a study late last year by the National Institute of Standards and Technology (NIST), researchers found evidence of racial bias in nearly 200 facial recognition algorithms.
  • Beyond a 12-month hiatus, we must acknowledge that while building AI is a technology challenge, using AI requires non-software development heavy disciplines such as social science, law and politics.
  • We require the intentional establishment of a field of AI whose purpose is to understand the development of neural networks and the social contexts into which the technology will be deployed.
  • For the population to gain comfort with broad deployment of AI so that tech companies like Amazon and IBM, and countless others, can deploy these innovations, the entire discipline needs to move beyond the CS lab.
  • Understanding human behavior patterns, biases in data generation processes are needed.

Ubisoft CEO lays out a plan to change the company's toxic culture

  • That’s sharply in contrast to reports from employees and statements posted internally, citing complaints made to HR in the past that they said have been ignored.
  • Even today, Chelsea O’Hara, touted as a success story of the company’s mentorship program, wrote extensively about the reality of her experience at Ubisoft where she felt marginalized and exploited.
  • An internal letter from Ubisoft CEO Yves Guillemot.
  • Beyond the ongoing investigations, Ubisoft says it has set up an online confidential alert platform where people can report harrasment or other inappropriate behavior, that’s run by a third party.
  • Otherwise, Ubisoft is adding a Head of Diversity and Inclusion that reports directly to the CEO, and Projects Director Lidwine Sauer has been reassigned as the Head of Workplace Culture where she will “examine all aspects of our company’s culture” and suggest changes.

Hugh Downs, anchor of '20/20' and 'Today,' dead at 99

  • Los Angeles (CNN Business) - Hugh Downs, the versatile and Emmy-winning broadcaster whose decades-long TV career ranged from anchoring ABC News' "20/20" to the "Today" show to serving as Jack Paar's sidekick on "The Tonight Show," has died at his home in Scottsdale, Arizona.
  • Downs -- who retired in 1999 -- was essentially there for the very start of commercial television, serving as the announcer for the children's show "Kukla, Fran and Ollie" and comedy legend Sid Caesar's "Caesar's Hour" in the 1950s.
  • Born in Akron, Ohio, Downs began working in radio after college -- a stint interrupted by his service during World War II -- before landing at NBC-owned WMAQ in Chicago, where he worked in various capacities for several years before moving to New York.
  • Guinness World Records once recognized Downs for having appeared in more hours of U.S. television (roughly 10,000) than anyone else, a record later broken by Regis Philbin.

Go is Boring...And That’s Fantastic! | Capital One

  • So we have to get better at writing software far faster than we got good at building bridges.
  • So, given these few, precious things that we know about how to build software and the hardware that we have available to us, let's take another look at Go. The Go language might lack features, but it ships with a great set of tools.
  • Since Go has changed so little, you can avoid the lava flow anti-pattern, where you can tell exactly how old some code is based on when a feature it uses was introduced into the language.
  • Interpreted languages running in virtual machines seemed like a good idea when CPUs were getting faster every day.
  • We have seen that Go focuses on the features and tooling that we know make it easier to create software and that better fit the memory and CPU architecture of modern computers.

ATO warns 8000 businesses over JobKeeper eligibility

  • The Tax Office could move to recoup JobKeeper payments from as many as 8000 small businesses around the country, after warning some employers may not be eligible for the payments.
  • Businesses and sole traders receiving the $1500 fortnightly wage subsidies have been told they face compliance checks by the ATO if they started operating after January 1, or where they had no assessable business income during the 2018-19 financial year.
  • The ATO is completing manual checks within identified groups, but warned businesses which don't meet the requirements could not receive taxpayer cash.
  • Labor has used the Eden-Monaro byelection campaign to heap pressure on the government to release its review into JobKeeper, completed last week by Treasury Secretary Steven Kennedy.
  • Dr Kennedy handed the report to Treasurer Josh Frydenberg last week and its release is expected before the government's economic update later this month.
