Dear Black people, Please learn how to swim (and code)!



Dear Brothers and Sisters,

This is a letter of caution and encouragement.

On August 2nd, 2010, 15-year-old DeKendrix Warner was enjoying the cooling waters of the Red River outside of Shreveport, Louisiana. His family and some friends had gathered for a late-summer barbeque. Several of the groups teenagers were splashing and playing along the shallow bank, when suddenly DeKendrix slipped into a 25-foot deep drop off. He didn’t know how to swim. He yelled for help. Three of his cousins, and three of his friends jumped into action to save him. None of them knew how to swim. Not 18-year-old Litrelle Stewart, not 15-year-old LaTevin Stewart, not 17-year-old LeDarius Stewart, nor 13-year-old Takeitha Warner, nor 14-year-old JaMarcus Warner, and not 17-year-old JaTavious Warner; they all drowned. None of their parents knew how to swim; they watched helplessly as their children sank one-by-one beneath the river’s surface, thrashing and screaming for help.

A man named Christopher Patlan heard the screams and saw what was happening. He was close enough to the scene that he was able to dive into the water and save one child: DeKendrix.

The six children that perished, the parents who watched powerlessly as they died, and DeKendrix are Black.

Mr. Patlan is White and Hispanic.

According to the Centers for Disease Control, Black children ages 5 to 19 drown at 5.5 times the rate of White children. Beneath the devastation that resulted from the ostensibly preventable loss of young, precious lives, is a legacy of bondage, discrimination, and segregation.

And the history and legacy of disparity in water safety knowledge and experience is eerily parallel to computer science.

In Stuck in the Shallow End: Education, Race, and Computing, Researcher Jane Margolis et. al, explain how the relationship of grade school structures, course offerings, student-to-counselor ratios, and belief systems held by students, parents, and teachers, has led to Blacks and Latino/as receiving a disproportionately low number of undergraduate and advanced degrees in computer science (around 7% according to American Community Survey data). Ms. Margolis connects today’s inequalities in access to rigorous computer science education to the past when Black slaves were forbidden to learn how to swim for fear they would escape, and Jim Crow segregation that prevented Black people from using public pools where they would have learned and refined swimming and water safety skills.

Perhaps DeKendrix’s cousins and friends would still be present, if that past never was.

In closing, I encourage you to read Margolis’s work as it beautifully lays out the case for re-thinking and re-designing the way Black children are prepared to take their places in the rapidly and incessantly evolving global economy. All Black children will not and do not need to major in computer science or become programmers. But, the problem solving skills characteristic of a proper computer science education can go a long way toward helping young Brothers and Sisters move people of color toward first economic, then social, and thus political parity.

Sincerely,

Technology and the Brothers

I dated Bitcoin, but I married Blockchain




Bitcoin is a movement by itself, but it’s a force when combined with Blockchain!

Shot out to Ne-Yo!

By now, you’ve probably heard of Bitcoin. Whether you’ve been the unlucky victim of a Ransomware attack and been directed to pay up in Bitcoin, or if you’ve been looking to further diversify your investment portfolio, you’ve probably read or heard about the first “cryptocurrency” that is all the rage these days. As of this writing the, the cost of one Bitcoin is approaching $17,000 USD. I’m no finance expert, but I’ve recently taken the plunge and invested, or should I say traded, a few bucks for a few fractions of Bitcoin. Hopefully, I’ll be able to retire off of my investment/trade in another 12 to 18 months! But, if not, I’m still excited about Bitcoin and especially the technology that undergirds it called BLOCKCHAIN.

I’m not going to go into the nearly 10 year history of Bitcoin and Blockchain, there are plenty of web resources out there to fill you in:




I only want to convey my high interest and enthusiasm for these platforms. The Blockchain in particular has the potential to revolutionize human affairs in much the way the Internet did.

Particularly, Blockchain is defined as a:

"...ledger of facts, replicated across several computers assembled in a peer-to-peer network. Facts can be anything from monetary transactions to content signature. Members of the network are anonymous individuals called nodes. All communication inside the network takes advantage of cryptography to securely identify the sender and the receiver. When a node wants to add a fact to the ledger, a consensus forms in the network to determine where this fact should appear in the ledger; this consensus is called a block."

A decentralized, secure, and immutable electronic ledger can be used to verify information needed to complete transactions all over the world, for much less than current rates charged by banks and other financial intermediaries, and in much less time (minutes compared to hours, days, or even weeks). But the Blockchain is not just a financial technology tool. It is currently being tested to develop driverless vehicles, store government data, and host educational competitions.

Now, RIGHT NOW, is the time to get familiar with the way this technology works, and to acquire the skills (i.e.- JavaScript, cryptography, Linear Algebra) needed to develop applications that can leverage Blockchain.

Free (for now) Learning Resources and Information:





So what’s in this for the Brothers (and Sisters)?

I Googled “Blockchain and black people”, and came across two very enlightening and very thought-provoking articles:

Two years ago, at the Atlantic, Kyle Coward asked, “Why Are So Few Black People Using Bitcoin?

Ed Dunn, via Medium, seeks to clarify the definition of “decentralization” as it relates to Blockchain, and states that Brothers and Sisters are Blockchain pioneers.

Given the developing hysteria surrounding Bitcoin, and the limitless potential of application for Blockchain technology, there is only one appropriate action to take.

Like Spike Lee said...

This YouTube video provides a good explanation of Blockchain, that literally anyone can grasp:
