casylum··on The Snapdragon 855's iGPU
Take a look at this. It sounds exactly like what you are describing.

Maybe this is something you could develop on instead of building your own.

casylum··on Roll Your Own All-Sky, Raspberry Pi Camera
Often it's the lens that results in poor quality images. You can get a RPi sensor with CS mount and add your own lens of your choosing. It's been a huge upgrade in quality and is relatively easy to do.
casylum··on Build List: A directory of on-demand manufacturers for your creative projects
https://www.oshcut.com/ has pretty good prices these days.
casylum··on IPv4 Address Auctions
Routing tables need to be limited in size in order for hardware to decide where to route packets fast enough. In the past hardware was more cpu and memory bound than the present.
casylum··on Why we’ve canceled flights, and what we are doing to get back on track
Lots of people leave the profession before becoming pilots at a major carrier.
casylum··on Micro-GPS: High-Precision Localization Using Ground Texture (2018)
It has been done successfully in the past. All you need to do is add the appropriate lens to focus further away.

Here they used an optical flow sensor for obstacle avoidance in a canyon. The closer to one side you got the faster the terrain would pass by the sensor. Allowing the UAV to self correct.

casylum··on GM warns some Bolt EV owners: Don’t park them inside or charge them unattended
Excessive dust can trigger false alarms. They make heat detectors for spaces like garages and attics.

casylum··on My Third Year as a Solo Developer
I'd be interested in any book recommendations on this topic too.

casylum··on How housing became the world’s biggest asset class
Ah, yes I missed that. Thanks for pointing it out.
casylum··on How housing became the world’s biggest asset class
SB50 allows for 4 and 5 story apartment buildings near "high quality" bus routes. This is a not the same thing as just allowing development near transit stations. If you look at a map of LA almost everything qualifies for development.

casylum··on Men Arrested at Courthouse Say They Were Sent to Test Its Security
Each state is different: https://toool.us/laws.html
casylum··on Wireless Carrier Throttling of Online Video Is Pervasive: Study
But then carriers would have a financial motivation to not upgrade tower capacity. The more congested - the more money they make.
casylum··on Append-only backups with restic and rclone
Does restic support sparse files yet?
casylum··on Tesla – Introducing V3 Supercharging
They are working on it:

casylum··on What Happened to OpenStack?
What are you using instead of DC/OS?
casylum··on Intel ends 5G modem alliance with Beijing-backed chipmaker
There is 5G and there is 5G mmWave. They are two separate parts of "5G". There are still advantages to sub 6GHz standard cell phone frequencies such as lower latency and higher throughput.

The disadvantages you mention only apply to 5G mmWave.

casylum··on Count the people around you by monitoring wifi signals
Sticker on the window?

There is an issue with retailers tracking shoppers movements in a store.

FTC take on the issue: https://www.ftc.gov/news-events/blogs/techftc/2015/04/privac...

casylum··on What Closing a Government Radio Station Would Mean for Clocks
It's not the phase stability that's important, but the accuracy and drift over time.
casylum··on ARM releases free Cortex-M processor cores for FPGAs
It is not uncommon to have lots of simple processors in one chip. One could manage low power mode, another encryption and boot, and another core functionality required in a hard drive. When you have 3-4 cores per device the license fees start to add up.
casylum··on Apple, Huawei Both Claim First 7-nm Smartphone Chips
System on chip. It usually refers to a cpu with integrated devices such as GPU, memory controller, camera interface, wireless, etc.
casylum··on Amazon Charges Couple More Than $1,000 to Ship Paper Plates
I had that happen to me once. The Amazon rep told me the item was being transferred to a warehouse near me before being shipped out "2 day shipping". That sounds like 7 day shipping to me.
casylum··on The future of AutoCAD
BricsCAD is pretty popular.

casylum··on Former Apple employees try a different management approach at Pearl Automation
OBD-II diagnostics are mandated by law, but manufactures often connect almost all microcontrollers to that connector. This allows updating all of your firmware from one port. That can be a security problem when connected to the internet.
casylum··on Uber’s self-driving cars start picking up passengers in San Francisco
I think traffic will get worse with self driving cars. If you don't need to be in the car, it can run errands for you during the day. Remember how computers were supposed to lead to a paperless office?
casylum··on If California's a 'bad state for business,' why is it leading in job/GDP growth?
California is growing in spite of its draconian business regulations. Perhaps things would be even better with more friendly laws for small businesses.
casylum··on Raspberry Pi Zero grows a camera connector
On the blog he they stated production of the Pi Zeros had to be delayed to build up the Raspberry Pi 3's. Now that the initial surge of Raspberry Pi 3's is done, they stated they will build "thousands a day" until demand is met.
casylum··on I Drove Chevrolet's Bolt
Tesla is not include Autopilot safety features out of the goodness of their hearts, they need to do it to stay competitive.
