MIT Celebrates Pi Day with “The Last Dean”

Short Films – I thought that “The Last Dean” is a very clever short (2:53) video.


Women and Computers in WWII – Intermission Story (22)

WWII – I read this a while back and have been meaning to reblog it. I thought it gave an interesting look back in history. It is a good, though quick, look at how women used computing to aid in World War II.

Pacific Paratrooper

Women with the ENIAC computer

Before the invention of electronic computers, “computer” was a job description, not a machine. Both men and women were employed as computers, but women were more prominent in the field. This was a matter of practicality more than equality. Women were hired because there was a large pool of women with training in mathematics, but they could be hired for much less money than men with comparable training. Despite this bias, some women overcame their inferior status and contributed to the invention of the first electronic computers.

In 1942, just after the United States entered World War II, hundreds of women were employed around the country as computers. Their job consisted of using mechanical desk calculators to solve long lists of equations. The results of these calculations were compiled into tables and published for use on the battlefields by gunnery officers. The tables allowed soldiers…

SpaceX Successfully Tests the Falcon Heavy

SpaceSpaceX tested its new, heavy launch vehicle the Falcon Heavy today. Not only was the launch successful placing a test payload into orbit, but it was able to successfully recover both of the flanking boosters at the Florida facility. At the time I publish this there is no word yet as to whether the main stage recovery on a barge in the Pacific was successful.

This will give the US a heavy lift capacity that it has not had in some time. With the ability to lift over 140,000 lbs, this rocket will be able to lift nearly three times the Delta IV-Heavy, TitanIV-B or Atlas V. This may be a significant step forward for missions to the Moon or more importantly to Mars.

The Cost of Industrial Robots Predicted to Decline


Robots – In a recently published article “Industrial Robot Cost Decline” by ARK Invest, they predict that the cost of industrial robots will drop 65% by 2025. They say:

. . . costs will drop by roughly 65%, to levels much lower than most analysts now anticipate, by 2025. Combined with advances in machine learning and computer vision, this drop in costs should cause an inflection point in the demand for robots as they infiltrate new industries with more provocative use cases.

These are just machines with a significant helping of electronics. It is no surprise that the price will fall as the technology matures, just as it has in so many segments of the electronics industry. This just adds to the rush towards more robotics and automation.

The big question looking forward is how will all of this automation affect society. It is a move that can’t and shouldn’t be stopped, but some long range planning is needed to keep the wide introduction of robots and AI from being disruptive.

Self Driving Autonomous Trucks NOW on Texas Roads

I saw an article “Self Driving, Robotic Trucks Now Hauling Appliances From El Paso To California” yesterday. I was not aware that autonomous trucks were being tested in Texas, if only for a short distance, along I-10 towards California.

Frigidaire, robotic truck tech maker Embark and fleet management provider Ryder Systems have been using automated trucks to deliver appliances from El Paso to a warehouse in California since October. While the trucks employ Level 2 system now with a driver aboard, their goal is for full autonomous operation.

I think that we will see more and more of this, with fully autonomous trucks on the road before long. You will find a little more on this pilot operation in “Embark’s semi-autonomous trucks are hauling Frigidaire appliances“.

November Issue of IEEE Central Texas Section Newsletter


I wrapped up the November issue of the IEEE Central Texas Section newsletter, The Analog. If you are interested in Tech and live in Central Texas, you may be interested in some of the events. IEEE Technical meetings are always open to the public.

Happy “Ada Lovelace Day”


It is the second Tuesday of October and that means that it is again Ada Lovelace Day. The day has been identified (per The Guardian) to:

. . . celebrate inspirational women in science, technology, maths and engineering, in the hope that by shining a light on such people and increasing their visibility, they can inspire future generations.

Ada Lovelace Day was founded in 2009 by Suw Charman-Anderson, and part of her reason for doing this was a worry that women in tech were invisible. The idea was a positive one – rather than highlighting the problem, highlight the unseen women and shout from the rooftops about all the amazing things they’ve achieved. Ada Lovelace was an obvious choice of mascot for such an endeavour.

Take this opportunity and join in some activity to recognize the contributions of women in technology. This would also be a good time to introduce or encourage a girl you know in STEM careers.

CapMac – In Austin, our local Capital Macintosh User Group is having a special program this evening. The featured speaker will be Rhonda Childress, the only Female IBM Fellow in Austin, the CTO of Security Services, a Sr. Certified I/T Architect, and an IBM Master Inventor.

Documentary – While not available today, there will soon be a documentary series, the Chasing Grace Project, about women in Tech.

The Chasing Grace Project is a documentary series about women in tech. It includes six episodes, each focused on a different topic within the women in tech narrative. From the pay gap, online harassment and female entrepreneurship to access to the best jobs, the decision to leave or stay in tech and the role of male allies, the series illustrate how we pave the way forward. Through story we can call out the adversities women face and illustrate how they’re navigating their own paths. The result? A series of blueprints for other women to find their paths, their way.

This may be something you will want to stay aware of

Review of “4th Rock from the Sun”


Book Reviews – “4th Rock from the Sun” eBook was published in 2017 and was written by Nicky Jenner ( This is Ms. Jenner’s first book.

I received an ARC of this novel through in return for a fair and honest review. I categorize this novel as ‘G’. The book covers all things about and related to the planet Mars.

While there is some scientific data, most of the book deals with side stores related to Mars. I feel like it just rambles on about topics associated with Mars.

Sigh . . . I had higher expectations for this book. I read about 20%, but at that point I just had to give up on it. I won’t call a Rule of 50 on it, but it just isn’t a book of interesest to me. I think there will be many who like this book, but I am not one of them.

My book reviews are also published on Goodreads (

An Overview of the New space Race

Space – I came across the article “Private companies are launching a new space race – here’s what to expect” this morning. it gives a very good overview of the companies and governments that are currently pursuing space programs.

If you are interested in space exploration, as I am, you will find this article of interest. The next decade will see many significant events if todays forecasts can be believed.
