Colleen Barry found a 25% lower death from opioid overdoses in states that legalized medical #marijuana
the #paper doi:10.1001/jamainternmed.2014.4005 “Medical Cannabis Laws and Opioid Analgesic Overdose Mortality in the United States, 1999-2010” on medical #marijuana. “Examination of the association between medical cannabis laws and opioid analgesic overdose mortality in each year after implementation of the law showed that such laws were associated with a lower rate of overdose mortality that generally strengthened over time.”

“When you share a link in a #Slack message, the link preview contains embedded information from #Twitter-Cards, #oEmbed, or #Open-Graph.” Apparently this is how to control how your links preview in Twitter and Fecebutt too. Also works in #RocketChat.
#Slack messages support “attachments” with titles, summary text, and images, and their “link unfurling” feature “automatically creates attachments” from contents of URLs.
This is how #Slack adds link previews to Slack messages.
#RocketChat didn’t use #Open-Graph preview information recently, but my testing seems to show that it does now, although this bug isn’t updated.

#paper #pdf #introduction to the SLAM (“simultaneous localization and mapping”) #robotics problem and the #algorithms for solving it, focusing on extended #Kalman-filters using a range measurement device. SLAM is the process of building some sort of model of the world your robot is in while also figuring out where you the robot is in that world. Unfortunately, this overview is from 2005, more than ten years old now, before the particle-filter revolution.
the "complementary filter" is an extremely simple alternative to #Kalman-filters for doing dead reckoning from an inertial measurement unit.

#pdf mentally ill Ronald H. Armstrong was electrically shocked, choked, and finally extrajudicially executed by suffocation by Jerry McDonald, Tina Sheppard, and Arthur Gatling, who had been sent to involuntarily commit him to a mental hospital because he was considered a danger to himself, though not to others; this court order grants complete impunity to the killers.
a brief comparison of #TensorFlow, Facebook’s Ronan Collobert’s faster #Torch-7, the Caffe convnets library, and Yoshua Bengio’s #Theano. “Just as a Tesla is yet another four-wheeled conveyance with four doors, a steering wheel and a roof, TensorFlow appears to be the best, most convenient library for #deep-learning, more worthy of anointment.”
Song Han’s new “EIE” #hardware for running #deep-learning #neural-networks with compressed (pruned and 5-bit-quantized) weights in on-chip SRAM runs “between 13× and 189× faster over regular CPU and also GPU implementations” and “the energy efficiency is better by between 3,000× on a GPU and 24,000× on CPU”. It’s very interesting to see an improvement of three orders of magnitude over the state of the art, particularly since what made deep learning practical over the last three or so years is in significant part (?) a single order of magnitude improvement in processing power. I’m not clear on whether this improvement exists for training as well (where you might not be able to get away with 5-bit weights), or just for inference.

Victor Hugo Morales, a well-known radio personality in #Argentina, has been fired from his popular radio show on Continental Radio. He says he’s being censored because he’s not in favor of Macri, the new president, who he says is “just a mask” for Clarín Group, which has now taken over the country. There’s a SoundCloud link to the talk he gave today on another radio station. (Listening to it, I can’t understand how people could stand to listen to his show.) #human-rights
This is the best advice I’ve ever seen about how to deal with a sexual assault afterwards.

#Twitter-cards use #OpenGraph tags including twitter:creator (your @username), twitter:description (up to 200 characters, or og:description), twitter:title (up to 70, or og:title), twitter:image (up to 1MB, or og:image), and a twitter:card for specifying the card type (summary, summary_large_image, etc.) These are all just meta@name values.
