ch··on The inventor of the screw-in coffin
Considering how difficult it can be to install a fence post in glacial till, this sounds like a less than exciting proposition.
ch··on Redpanda – A Kafka-compatible streaming platform for mission-critical workloads
For those eager to get a look at the code it can be found here: https://github.com/vectorizedio/redpanda
ch··on Vectorized mentoring students in Distributed Systems
I helped early on to review this plan for Alex and the Vectorized team, so I’m very excited to finally see it be released to the world.

Vectorized consists of quite the lineup of engineers (https://vectorized.io/team) and anyone who gets to be mentored by them will be gaining a huge advantage when it comes to Distributed System design and implementation!

ch··on Capitol Hill Autonomous Zone

    Chief Carmen Best may be totally wrong or making that up.
https://www.businessinsider.com/seattle-police-retract-claim...

As it turns out she was, in fact, wrong or making it up.

ch··on Robinhood Is Down Again?
Probably a JVM GC pause.
ch··on Don’t try to sanitize input – escape output
One's output is another's input.
ch··on Later school start times are associated with more sleep and better performance
And yet work start times won't adjust.
ch··on Allocator Designs
Would the author mind commenting on how the diagrams were generated? They were very clear and useful.
ch··on Anatomy of a Scam
Don't investors ever ask to meet the team first? Seems like a fair ask if one is to invest.
ch··on Show HN: The best technology podcast episodes
Since there is relatively little information on the linked page, I'll put some questions I have here.

1. How does it work? It would appear the list is user curated. New submissions are from users (via submit) and ranking is based on hearts? Is there any future plan to be able to associate # of plays with a given episode (not sure if podcast app apis allow this).

2. In relation to #1 (an asked already by others), how can I subscribe to this in my podcast app?

ch··on iRobot Terra Robot Lawn Mower – First Impressions
I feel like they missed a golden opportunity to let users select between various space filling curves for the cut pattern.

I, for one, would love to have my lawn cut in a Hilbert Curve pattern.

ch··on Help me ask why you didn't just
Honestly, if they aren't asking for help formulating a solution, they also aren't asking for your suggestion to an alternative (even if you try to couch it in terms of a question). So just don't ask and you won't have the issue.
ch··on Linear Algebra and Applications: An Inquiry-Based Approach
Cool. I want to try and work through this text, just to assess how useful it is.

The approach is an interesting one.

Looks like this will have to become a weekly goal. Maybe one chapter a week? Seems possible.

ch··on Yubico launches its dual USB-C and Lightning two-factor security key
Something like this would suffice, if it was simple to keep along side the key: https://tripplite.com/usb-c-female-to-usb-a-male-adapter~U32...
ch··on I Tried Hiding from Big Tech in a Pile of Privacy Gadgets
But do you also segregate the devices and networks you connect to for this identity, or can a sufficiently advanced adversary connect the dots where you link up with the rest of the internet?
ch··on Details of the Cloudflare outage on July 2, 2019
They still retain the global rollout for the other use cases detailed in the write up, so its generally tested, though not for this one use case as you point out. I suspect the tradeoff is reasonable, however having a short pre-stage deploy before global in all cases would be a more conservative option that would prevent an emergent push from becoming an even bigger emergency!
ch··on A Gas Heist Gone Wrong
And we certainly have never interfered in any economic sense in Venezuela ... hold on, my producer is telling me that this is incorrect.
ch··on Snagging Parking Spaces with Mask R-CNN and Python
Cool. Can we add infrared detection to determine if the car is just standing rather than parked, so you can eliminate the cases where a car is not in a parking spot, but would appear parked to this detector?
ch··on Benefits of talking to strangers
You ever sit there wanting to strike up a conversation with a random stranger, and have no idea where to begin?

I think that has more to do with the observed self-imposed isolation than is given credit in the article.

ch··on Animated Knots: Learn how to tie knots with step-by-step animation
Great looking site. I just grabbed the app because I've been using the "What Knot to Do" app forever now, but find these animated single page descriptions more concise!
ch··on ElectionGuard – A free open-source voting SDK
Cool use of Hom encryption, but does nothing about disenfranchisement.
ch··on A final proposal for Rust await syntax
Nice insight into the amount of thought going into this design proposal. It's always tricky to introduce new syntax to a language and re-using the field access notation here isn't as icky an approach as it first looks.

I don't know enough about rust to understand how this would operate during compile time w.r.t if a user tries to define a field named 'async'. Is that no longer allowed or would the compiler be able to disambiguate?

ch··on Hundred-Tonne Robots That Help Keep New Zealand Running [video]
Really like how they minimize wear to the pavement by just shifting the location of where the robot operates each time through a cycle.
ch··on Generating More of My Favorite Aphex Twin Track
Sadly these office windows that surround me don't open up, and so I'm left to listen to your awesome work paired with the hum of AC blowers and fluorescent light ballast.
ch··on Scylla Summit 2017: SMF: The Fastest RPC in the West [video]
Associated slides: https://www.slideshare.net/ScyllaDB/scylla-summit-2017-smf-t...
ch··on Baltimore State Attorney Drops Dozens of Cases: Body Cam Shows Drug-Planting
It would be interesting if not only EMT training was required, but also some number of years as an active EMT. Having to respond to various scenes involving law enforcement, but not being blessed as law enforcement would provide an interesting perspective on police response.
ch··on Pi-hole – A black hole for Internet advertisements
Would have been interesting to know who the domain was homed to. Might have just been an ad network with a CDN and cadillac.com CNAME'd to their servers. Looks like an origin served ad, but still flows through the tracker.
ch··on Chronix: Long term storage/retrieval for anomaly detection in operational data
Clever use of timestamp inference with thresholding. Making use of domain specific knowledge to erase data is always an efficient form of compression!
ch··on Enter your address and find out everyone who represents you in U.S. government
Funny. The results keep coming back empty for me.
ch··on Achieving Scale in the Decentralized Web
Sure I get that. What you call "The P2P Web", I call "The Web". Now if you want to talk about P2P Twitter, that is a different animal.
