"Job seekers have have negative sentiments around several issues." In other news, the sky is blue

This exactly!

I miss this style of quirky magazine layouts. The web has made everything follow the same 12 column grid template with just one or two sans-serif fonts.

Not sold, but shared internally across multiple clients with no functional opt out: Once Democratic party digital firms like NGPVAN and ActBlue get your email, be prepared to get multiple emails per day from candidates across the country you've never heard of (much less could even vote for) constantly sending you garbage emails. The unsubscribe buttons do nothing.

I'm curious if there's a site tracking new software for vintage platforms such as ssheven which is a modern SSH client for Mac OS 7/8/9. For the occasional retrocomputing enthusiast, it'd be great to have a dedicated resource tracking all the great new work the community is producing. (And a way to also collaborate/give back via open source.)

History repeats itself. Check out the story of the Molly Maguires, a somewhat vigilante labor group in PA's coal region, who were infiltrated by an undercover Pinkerton in the late 1800s: https://en.wikipedia.org/wiki/Molly_Maguires#In_the_United_S... I'm from the region of PA where this all happened, and it's a well-known story among locals.

Thank you!

Thanks!

Good idea! I'd want to do some research and simulations to figure out how much of an altitude hit I'd take with the added weight of an additional controller.

Yeah taking the Uber route on regulation compliance does not work for space travel.

Really helpful! Thank you! Would you happen to have your source code available anywhere for me to take a look?

Thanks!

Haha that's awesome. Do you have a link for a good tutorial on them?

I'm not totally certain. I could do a quick C++ POC to see if that improves throughput a bit, but I've got doubts. My other thought is that the SPI interface only can go up to a certain speed. If anyone has deeper knowledge of that protocol I'd love to hear their thoughts.

I'm in the DC area where anything that goes up in the air is taken very seriously.

Hey man! I hope you're doing well! Maybe I'll paint the next one green and white!

(For the rest of the world who's confused by this: college fraternity colors.)

I looked into the Feather for a bit, but my experience with the Pi is much stronger, so I felt more comfortable working with that after I determined the battery I'd need to power it wouldn't be too heavy to lift.

I'd like to eventually start working with those more high-powered motors, but for a first flight I wanted to keep things manageable.

... and I also had a 400 ft limit with my permit.

That's exactly it. This thing was pretty heavy with a battery, Pi, sensors, mounting components, etc. I used an Estes D12-5 engine, which is fairly powerful but there are wayyy more powerful model rocket motors out there that I'd like to try in the future with this.

Hi! Here's the post where I document my build process: https://johnjonesfour.com/2020/10/03/model-rocket-telemetry-... Happy to answer any questions about that!

For the video issue, I need to do some homework and figure out what the issue is. It's just speculation at this point. Yes, I am saving the Pi's microSD card.

Telemetry transmission and reception is done by an Adafruit RFM95W, and I'm using this library to interface with it: https://github.com/adafruit/Adafruit_CircuitPython_RFM9x. It handles data just as Python byte arrays, and I only transmit data from the senors (in real time) but not video. I use that library to determine RSSI as well.

Thanks for the note on the language idea. Like I said in the post, I want to be talked out of that :-)
