Partnership between Boston Dynamics and Otto Motors makes warehouse automation safer; A paper claiming a link between the Sun and global warming was retracted. The authors dispute the action.; Computers suggest that between 1700 and 1910, Beethoven was the most influential piano composer and Rachmaninoff was the most innovative; A new AI chip makes image recognition much faster; and a Steem author reviews the Brave Browser

  1. Boston Dynamics' Handle Teams Up With Mobile Robots on Warehouse Logistics - In today's awesome robot video, IEEE Spectrum covers a partnership between Boston Dynamics and Otto Motors. Boston Dynamics' Handle robot is good at moving and lifting heavy objects in a warehouse environment, but it's flexibility for that task makes the kinds of sensors that could protect nearby people impractical, so it may be unsafe for people to work around the robot. To solve this dilemma, Otto Motors' autonomous mobile pallets come in and bridge the gap. These robots can safely move objects from an environment where humans are working to an environment where Handle is operating (and back).

    Here is a video:

  2. Heavily criticized paper blaming the sun for global warming is retracted - In 2019, Nature published the paper, Oscillations of the baseline of solar magnetic field and solar irradiance on a millennial timescale. Lead author Valentina Zharkova reported that the work was funded in part by the US Air Force and the Russian Science Foundation. The paper claimed that the Sun's magnetic field could be driving global warming, but it was immediately met with criticism. For example, Ken Rice argued that it made an elementary mistake by claiming that the distance between the Sun and the Earth changes as a result of the Sun's movement "around the barycentre of the solar system". On the other hand, the paper was well received by people who are skeptical of the notion that global warming is being caused by human activities. The journal has now retracted the article, saying that, "Current ephemeris calculations show that the Earth-Sun distance varies over a timescale of a few centuries by substantially less than the amount reported in this article." The authors responded to Retraction Watch with a link to the corrected article and saying that the article should not have been retracted for such a minor correction. They also argued that the criticisms and the journal's retraction notice are incorrect because the original paper said that, "the Sun-Earth distance would change UP to 0.02 au not that it would change BY 0.02 au."

  3. Computers Confirm Beethoven's Influence - Scientific American's 60 Second Science podcast discusses a recent article was published in EPJ Data Science, Novelty and influence of creative works, and quantifying patterns of advances based on probabilistic references networks. In this work, Doheum Park, Juhan Nam, and Juyong Park described their work comparing 900 pieces of piano music from the baroque, classical, and romantic eras. When they examined chord transitions for novelty, they found that Rachmaninoff was the one with the most creative transitions and Beethoven was the one whose work was most borrowed from. The analysis was conducted by breaking each of the 900 works down into smaller segments, or chunks, and then comparing the chunks.

  4. A new AI chip can perform image recognition tasks in nanoseconds - A new type of artificial eye works by combining light sensing electronics with artificial intelligence (AI) on a tiny chip. As a result of its size and tight integration, the device can operate without passing around data, which means that it can perform image recognition tasks far faster than existing technologies. This may be useful for technologies that range from autonomous vehicles to factory robotics and remote sensing. The chip is built with diodes on a sheet of tungsten diselenide that's just a few atoms thick. And the diodes are wired together into a neural network. The material of the chip gives it special properties, so that the diodes' photosensitivity can be adjusted externally, which enables training of the neural network. As-of now, the chip only has 27 detectors, which means that it's limited to recognizing blocky, 3x3 images, but the researchers claim that scaling it up would be straightforward.

  5. Steeem @shaden: How good is Brave Browser? An Honest Product Review - This post by @shaden starts by describing the problem that Brave was created to address. Namely, advertising, tracking, and other malicious web-site ad-ons invade our privacy, slow down our devices, and increase our bandwidth costs. Brave was launched to make it easy for users to avoid these negative consequences of life on the Internet while creating alternative revenue streams for advertisers and publishers. According to the author, the browser also enhances privacy through the use of the duckduckgo as a default search engine as well as forcing the use of the https protocol. Beyond that, it lets users opt in or out of receiving ads, and distributes Brave Attention Tokens (BAT) to users who elect to receive them. The author goes on to report their own observations, which include the fact that the browser has a familiar "look and feel" because it's built on the Chromium engine, and also that web pages load faster and look cleaner. Drawbacks, however, note that Brave Shields must be disabled for some sites to work and that it's not able to block entire pages that are meant to be advertisements. Perhaps the stronger endorsement is that that the author has switched to using Brave as their primary browser. (A 10% beneficiary setting has been applied to this post for @shaden.)

Not related, but now your post looks very nice on the SteemSTEM app (see here). The latest app update made that possible. I hope you will like that (the display was somehow broken with the formerly deployed version).

Now back to the topic, the second item made me thinking... Again... This kind of things won't help.

It does look nice on SteemSTEM now. Thanks! Overall, I really like the look of that site. I'd use it more often, but I usually use steempeak so I can schedule my posts a day in advance.

On a related note, have you noticed that photos from SteemSTEM don't always get pulled into facebook shares? I have tried sharing some steemstem.io URLs through facebook, and wound up having to delete them and share a steempeak or steemit link because facebook wouldn't display the image with the link from SteemSTEM.

You can see an example if you go here - https://developers.facebook.com/tools/debug/

And try to scrape this link - https://www.steemstem.io/#!/@carloserp-2000/what-did-lorentz-and-1582577933

Not sure what's going on, but for some reason, Facebook was able to scrape the photo when I shared the steemit link, but it couldn't scrape the photo when I tried to share the steemstem.io URL. I'd like to share SteemSTEM URLs to try to direct traffic to the site, but I think people tend to ignore links without photos.

I know the problem, and this would require to change entirely how the app routing works (the #! in the address is the problem). Historically, this app has been released by two developers who left more than 1.5 year ago. I took over from them and learned Javascript from scratch. Now, I am probably capable to develop something that works, but this means a lot of changes at the code level. The problem is that the current code is not really suitable for this.

I am planning to do so in the version 2.0 of the app, which I may start working on on a regular basis later this year. I apologize for this. I can't fix it now :(
