natvert··on Let's hear scientists with different Covid-19 views, not attack them
The fact that this article exists, and needs to exist, worries me more than any virus or lockdown.

What, if anything, is more necessary to a free society than the free expression and debate of ideas?

This of course requires a literate and critical interpretation of the facts and data by all, but I digress. This is science.

natvert··on Daily Covid-19 Update from Dr. Smith at Columbia
Dr. Craig Smith's daily letters are a fantastic source of non-politicized information on the outbreak.
natvert··on Why we’re not overreacting to the coronavirus, in one chart
A related and well worth-reading analysis: https://www.zerohedge.com/health/covid-19-evidence-over-hyst... which makes the point that none of these numbers are adjusted for country population (or pop density)

Also, why the article is not on medium, where it was originally: https://www.wsj.com/articles/controlling-the-virus-narrative...

natvert··on The Military Is Building Long-Range Facial Recognition That Works in the Dark
Dead link?
natvert··on Google clamps down on free storage
I love the irony of this: I open the article and start reading. I am told that Google lured us in w/ free storage, but now I'm going have to pay since I've used so much storage. Then, a popup is overlaid on the article and the text is hidden. The popup says this article isn't actually free. I've read too many free articles on Bloomberg and now I'm going to have to pay for a subscription to keep reading.

I don't know what to take away from this other than the reminder that every public company has a duty to shareholders to take people's money! That's the function of a company: profit. What do we really expect here?

natvert··on Robel: Robotics Benchmarks for Learning with Low-Cost Robots
our lab uses Dynamixles in the widow x (https://www.trossenrobotics.com/widowxrobotarm) and the servos alone are 70% of the total cost.

is anyone aware of an open-source alternative to these servos? this would be a great contribution to the community, if not available already

Feeling the competition from Robinhood app?
natvert··on Offline Speech-to-Text on Raspberry Pi Zero
The linked video is just an advertisement. The interesting work is: https://ai.googleblog.com/2019/03/an-all-neural-on-device-sp...

Ok, but 2 or 4 spaces?!
natvert··on Chrome 69 Is a Full-Fledged Assault on User Privacy
Or Brave browser?
natvert··on Building a Reflow Oven
I also designed and built a reflow oven! My goal was to make it simpler / smaller: https://nathan.vertile.com/blog/2019/04/24/fluxlamp-the-sold...

Email me if anyone wants control boards and I can try to make some more.

natvert··on An Arduino-type board for AC power (phase-fired) control
Thx for the feedback and the heads up. What browser are you using?
natvert··on YOLO: Real-Time Object Detection
Good question, we use the same method as coco, described in https://arxiv.org/pdf/1405.0312.pdf and implemented in the coco evaluation scripts here: https://github.com/cocodataset/cocoapi/blob/master/PythonAPI... -- basically the best matching proposal, ground truth pair
natvert··on YOLO: Real-Time Object Detection
Thx, I'll check that
natvert··on YOLO: Real-Time Object Detection
Interesting this is trending now. We have actually just recently released an improved version of YoloV3 (called G-Darknet) https://github.com/generalized-iou/g-darknet, using GIoU as a loss, which is described here: https://giou.stanford.edu

Also notable in G-Darknet are some tools useful for training (called darkboard), see https://github.com/generalized-iou/g-darknet/tree/master/dar...

natvert··on Google Fit Closing in 30 Days
Should be re-titled to say just the website is shutting down.

natvert··on Intel Unveils the Intel Neural Compute Stick 2
Anyone know someone at Intel or how to actually buy the Myriad X to use in other hardware designs? I have reached out to Intel multiple times with no response.
natvert··on Picovoice – Embed private voice AI into any product instantly
Is this not just https://github.com/ARM-software/ML-KWS-for-MCU trained on new keywords? Maybe I'm missing what is so special here?
natvert··on New Google Pixel 3, Pixel Slate, and Home Hub
After bad experiences with hardware reliably and support on the Nexus 5 and Nexus 6p, I will not be buying another piece of Google hardware.

Although, I must say, the vanilla Android software experience is top notch. I'd just rather install / customize it on more reliable hardware with better support (my op5t has been amazing!)

natvert··on FAA to consider increasing Light Sport Aircraft weight limit to 3,600 pounds
So, as long as I'm in my drone, it's fine. If I fly FPV, though, woah hold on, too dangerous!
natvert··on Ask HN: What is your best advice for a junior software developer?
Be nice. Work hard.
natvert··on One Billion Apples’ Secret Sauce: Recipe for Apple Wireless Direct Link Protocol
Wow. No love. Isn't lack of root like buying a house but the builder refusing to give you a master key or permission to change the locks?
natvert··on One Billion Apples’ Secret Sauce: Recipe for Apple Wireless Direct Link Protocol
Or lack of real software ownership e.g. no root allowed!)
natvert··on How China Systematically Pries Technology from U.S. Companies
It's hard for me to believe that all the smart, capable company executives involved in planning and execution of operations in and around China are oblivious to IP risks.

There is an obvious upside of operating in Asia, both cheap labor (though now decreasing) and strong work ethic coupled with access to a huge market.

It seems to me that execs understand and take a calculated risk when they choose to do business in various parts of the world. If they cannot make this calculation, they should not be running a company.

More than anything else, the attitude displayed in this article appears to me as an attempt to defer (or pass to the public) the consequences of the above calculated choices. If not directly, through a trade war that will hurt all Americans. All the while, these companies keep their financial gain private, in the pockets of execs and shareholders.

There is something to be said for protecting IP in the interest of a country's defense, but the technology that qualifies for this type of protection should be the subject of public debate, not a president's whim. Furthermore, unless the companies that own this IP are taken over by the state, company execs will always be free to make the decision re. operating in Asia and between the associated IP risks and capital gain.

natvert··on Build a do-it-yourself home air purifier for about $25
Um... Why the down vote? "Terrell used a sensitive air-quality meter to demonstrate that one high-end HEPA system brought the particulate count in a dusty room down to virtually zero. His homemade system brought the count down to about 10 percent of its former level."
natvert··on Build a do-it-yourself home air purifier for about $25
Am I reading this right, 10% air quality improvement for the diy version vs 100% for a retail device?
natvert··on Millennials and Mainframes: How to Bridge the Gap
Ok, maybe this is a silly question, but I am a millennial.... Question: what is a mainframe and why would I want one? In my mind I think of it as a big, but inelastic, compute resource. If that's true, why wouldn't I want to use something horizontally scalable instead?
natvert··on Switzerland: Welcome to the Drone Valley
Also, for folks interested in general "drone" (aka research/commercialized/militarized robotics) news, the http://dronecenter.bard.edu/ newsletter provides fantastic weekly coverage.
natvert··on Switzerland: Welcome to the Drone Valley
If you want a mavic, just buy a mavic, building something with this level quality / reliability is not worth the effort.

The advantage to building your own is that you get a different type of quad -- a racing quad which feels more like flying a porsche (feels like a race car) than an mini-van (e.g. mavic, reliable but super fun to fly).

If you want to build a racer, rctimer has some of the best kits (high quality parts, well thought out design). Here's an old build guide from my blog, you would want to get a newer kit with an omnibus-based flight controller, but the idea is the same: https://nathan.vertile.com/blog/2016/04/24/rctimer-u210-mini...

Also, if you're just learning to fly, you probably want to learn acro/rate mode (which is full manual mode) on something smaller first, like this maybe: https://nathan.vertile.com/blog/2017/03/31/betaflight-micro-...
