Blockchain Used To Hide Contraband Images

"Child abuse imagery found within bitcoin's blockchain":
Since mining is essential for the function of bitcoin, as the process records the transactions into the blockchain to verify trades and generates new bitcoin in the process, having illegal content such as child abuse imagery within the blockchain could cause significant issues for the currency.

[Off Topic] Hsieh Forbes Column: Any Study Of 'Gun Violence' Should Include How Guns Save Lives

[Off topic] My latest Forbes column is now out: "Any Study Of 'Gun Violence' Should Include How Guns Save Lives".

I discuss three key principles that should be included in any kind of "gun violence" research, including:
  • Firearms save lives as well take lives. 
  • The value of firearms in the hands of law-abiding citizens should be measured in terms of lives saved or crimes prevented, not criminals killed.
  • The right to self-defense does not depend on statistics and numbers.
Legal use of firearms in self-defense happens a lot more often than most people realize.

Any public health research that studies only the negative effects of criminal misuse of guns while ignoring the positive lawful uses misses a critically important part of the picture.

False Confessions Update

NYT: "False Confessions, Mistaken Witnesses, Corrupt Investigators: Why 139 Innocent People Went to Jail".

Particularly chilling:
In just under half of the exonerations last year, defendants were wrongfully convicted in cases in which no crime was committed. This included more than a dozen drug possession cases, 11 child sex abuse cases and nine murder cases.

In one case, Rodricus Crawford, who was on death row in Louisiana, was exonerated. The state dismissed all charges against Mr. Crawford last year after officials acknowledged that evidence suggested his infant son died with pneumonia and bacteria in his blood, implicating sepsis in the death rather than murder.

Affordable 3D-Printed Homes

"This cheap 3D-printed home is a start for the 1 billion who lack shelter":
Using the Vulcan printer, ICON can print an entire home for $10,000 and plans to bring costs down to $4,000 per house. “It’s much cheaper than the typical American home,” Ballard says. It’s capable of printing a home that’s 800 square feet, a significantly bigger structure than properties pushed by the tiny home movement, which top out at about 400 square feet. In contrast, the average New York apartment is about 866 square feet
