Join us next Wednesday, April 3rd to learn how to calibrate multiple cameras and LiDARs using Tangram Vision's MetriCal multimodal sensor calibration suite. Registration is open now at https://t.co/NfqwxkG4Jd

[Greg Schafer @grschafer]

We're launching the HiFi 3D sensor today! It ups the spec for 3D sensing with more resolution, lots of AI power, and neat features like self-calibration. Check out the campaign! https://t.co/GClWc9WbXS #3dsensing #robots #robotics via @tangramvision

Looking for something to fun and free to play this weekend?

If you liked the Command and Conquer series, Dune II, and Total Annihilation then you will love Beyond All Reason (BAR) - an open source RTS game for Windows and Linux: https://t.co/kyZ6m4UJGg.

@saveman71 @TangramVision Doh, my mistake! Yes, that should be website_root -- it was correct in the code repo but I forgot to copy that edit over to the blogpost. Those issues are both fixed now, thanks for pointing them out!

[Greg Schafer @grschafer]

I recently fell down the rabbit hole of "how do you time how long a query takes in PostgreSQL?" and wrote up what I found. If you read it, let me know if I missed anything or if you learned something new!

[Tangram Vision @TangramVision]

How do you time queries with PostgreSQL? There are many ways - and we’ll demystify them for you in our latest post! https://t.co/X8YhnUSDGj

You use fiducial markers...but do you know what goes into *making* a fiducial marker? It's fascinating...so we broke it down in our latest perception tutorial. #computervision #sensors #perception #fiducialmarkers #opencv #kalibr #apriltag https://t.co/5cUPLVtWa3

What happens when classic Mini meets modern sensors? Armed with @VelodyneLidar Pucks and an @IntelRealSense D435i, we set out to discover the answer at @joshu's @selfracingcars. Read about it in @therobotreport:

It's not just sensors and robots at Tangram Vision. We grapple with web challenges, too. In our latest post, @grschafer shows how to use (well, abuse) #terraform to upload static websites to #s3

Calibration. Bundle adjustment. Sensors. We discuss it all here: https://t.co/LBgTkxFNgd #calibration #computervision #bundleadjustment #opencv

We work at the intersection of many sensor modalities; so many that we need an industry map to organize the key players for each type! #Robotics #AutonomousVehicles #sensors #lidar #3dsensor #imu #computervision https://t.co/ZhQU86UWfQ

[Greg Schafer @grschafer]

More writing about Postgres! This article gets a little more intense than the last one, with lots of sample code. Feedback/suggestions/corrections welcome!

[Tangram Vision @TangramVision]

May Day is the perfect day to create PostgreSQL test data, don't you think? #postgresql #sql #python #testdata https://t.co/TWShlHNufA

[Greg Schafer @grschafer]

I recently dove into loading and generating test data for PostgreSQL and wanted to collect + share what I learned. This article is part 1 of that effort -- hope it helps others learn something new! Feedback always welcome!

[Tangram Vision @TangramVision]

What tools and approaches are available to create and load test data for webapps without an ORM, and which work best? Our guru of all things web @grschafer
helps demystify this! #sql #postgresql #webappdevelopment https://t.co/lnU9hT4TRC

We're excited to relaunch Rust for RealSense. We've taken over this project, updated it, and improved it. If you're building a vision-enabled device with Rust, you can now add any RealSense sensor. #realsense #rustlang #robotics #computervision https://t.co/OLZC7UeinA

Should you choose a grayscale or RGB camera for your next vision-enabled project? Tangram co-founder @bminortx weighs in with a guest tutorial at the @opencvlibrary blog. #opencv #computervision #robotics #cmos #tangramvision https://t.co/CjOQgrvbUR

[Alex Iskold | 2048.vc @alexiskold]

Thrilled to partner with Brandon and Adam announce @2048vc investment in @TangramVision

Excited to help them build the vision platform for robotics.

What happens if your robot can't see? With sensors being deployed more frequently in dusty, dirty environments on platforms like robots, drones and AVs, sensor cleanliness needs more exploration. #computervision #sensors #robotics #drones #automation

Great documentation is one of our top priorities. Using #Rustdoc as our foundation, we've collected a set of best practices for documenting our Rust codebase that translate to any project being built in @rustlang :

I wrote a new blogpost, providing an introduction to Ansible + using it to automate WireGuard VPN server + client setup! There are a lot of small details + conventions in Ansible -- I hope this tutorial helps uncover some of those and make learning faster. Feedback welcome!

[Tangram Vision @TangramVision]

Our master of all things Web, @grschafer, posts Part II of his @WireGuardVPN setup tutorial. If you want to learn how to increase server uptime, relay traffic and more, this series provides in-depth code examples. #wireguardvpn #ansible #automation
