Should Teachers Get $100 For Steering Kids To Google's 'Hour of Code' Lesson? 89

Tomorrow's "Hour of Code" kick-off event features Melinda Gates, Facebook COO Sheryl Sandberg, YouTube CEO Susan Wojcicki, and "multiple state governors," reports theodp -- who has some concerns. With Microsoft boasting that nearly 70 million of its Minecraft Hour of Code sessions have been launched, and tech companies pushing coding and their products into classrooms, it's probably no surprise that the 2017 Hour of Code -- organized by tech-bankrolled Code.org -- seems to have presented a too-hard-to-resist branding opportunity for Google, Microsoft, Apple and Amazon.

And, in what might evoke memories of Dollars for Doctors, some teachers will even be rewarded for steering their kids to Google's Hour of Code lesson. "Thanks to our friends at Google," explains crowdfunding website DonorsChoose.org, "4th-8th grade public school teachers who engage their students in a 'Create your own Google logo' Hour of Code activity can earn a $100 DonorsChoose.org gift code -- and have the opportunity to receive one of five other grand prizes (including $5,000 in DonorsChoose.org credits for your school!)."

StartCom Will Stop Issuing Certificates, Revoking Them All in 2020 (startcomca.com) 42

thegarbz writes: Startcom, a certificate authority which as we covered previously has been distrusted by Mozilla, by Google, and recently also by Microsoft, has announced that it will cease trading as a Certificate Authority. While their website currently shows no indication that their certificates have any problems, a news posting has announced their intentions to stop providing certificates as of January 2018, and to revoke all remaining certificates in 2020.
The original submission also says StartCom sent an email to all their former customers -- including customers of their free StartSSL certificates -- announcing their intentions. As you are surely aware, the browser makers distrusted StartCom around a year ago and therefore all the end entity certificates newly issued by StartCom are not trusted by default in browsers.

The browsers imposed some conditions in order for the certificates to be re-accepted. While StartCom believes that these conditions have been met, it appears there are still certain difficulties forthcoming. Considering this situation, the owners of StartCom have decided to terminate the company as a Certification Authority as mentioned in Startcoms website.

StartCom will stop issuing new certificates starting from January 1st, 2018 and will provide only CRL and OCSP services for two more years. StartCom would like to thank you for your support during this difficult time.

Can Researchers Detect Irregular Heart Rhythms with the Apple Watch? (usatoday.com) 42

An anonymous reader quotes USA Today: Might wearing an Apple Watch save you from a stroke or cardio problem? Apple is careful not to make that direct claim. But the company, in collaboration with Stanford University School of Medicine, launched the Apple Heart Study app on Thursday that uses the heart rate sensor inside the Apple Watch to collect data on irregular heart rhythms... If an irregular heart rhythm is detected, participants in the study will be notified through the Apple Watch and on their iPhones. Should that occur, you'll be offered a free consultation with a study doctor, and possibly an electrocardiogram patch for additional monitoring...

A participant in the study merely has to download the app and wear the watch... The way Apple explains it, a sensor inside the watch uses green LED lights flashing hundreds of times per second and light-sensitive photodiodes to detect the amount of blood flowing through the wrist. The sensor has an optical design that gathers signals from four distinct points on the wrist. Using software algorithms, the Apple Watch can isolate heart rhythms from other noise, and identify an irregular heart rhythm.

The FDA has also approved the first personal electrocardiogram accessory for the Apple Watch, according to TechNewsWorld. "The KardiaBand" also detects and records atrial fibrillation that can lead to strokes or other heart problems. "The user simply touches an integrated sensor, and the results are then displayed on the face of the Apple Watch."

An irregular, bloodflow-disrupting heartbeat is the top cause of strokes, which kill 130,000 people every year just in the U.S. -- in many case before they've experienced any symptoms.
