New comment by rwoll in "iNaturalist"

Strava (a running tracking app) provides two helpful controls you can set as your default:

1. “Hide the start and end points of activities that start at SPECIFIC addresses.” 2. “Hide start and end no matter where they happen.”

Then it can be useful to add your home/work/routine locations.

If iNaturalist doesn’t have a setting like that, it’s a nice approach — especially if it’s included as part of initial onboarding flow — so it helps people without needing to remember to make visibility choices each time.

> Treating it like a stop sign also doesn't work very well when there are huge amounts of pedestrians. As a pedestrian that yesterday meant I got the right of way all the time. For cars it was mayhem downtown.

I’ve long been curious if people in S.F. who are used to Waymo “behavior” – including myself – behave differently when a Waymo is involved. For the most part, Waymos are extremely predictable and if you’re on the road as a pedestrian, cyclist, or car, are you more aggressive and willing to assert your turn in the road? Curious if Waymo has done a psychological study of how we start to think about the vehicles. I know many runners, for example, that’ll stride right into the crosswalk in front of a Waymo but wouldn’t dare to do that in front of other cars. Similarly, anecdotally people treat public transit vehicles differently than a civilian car: folks are more willing to let them drive even if out of natural turn.

Prior to reading the article, I assumed Waymos were stuck due to an Internet connectivity issue. However, while the root cause is not explicitly stated, it sounds like the Waymos are “confused” by traffic lights being out.

It’s a great tool! Docker for Desktop is now shipping with a lot of the same features built into its GUI, too.

This has been instrumental in importing and generating configs from existing infrastructure.

New comment by rwoll in "Signed HTTP Exchanges (SXG)"

rwoll — Sat, 04 Jul 2020 19:38:59 +0000

While reading through https://news.ycombinator.com/item?id=23729160, discussions around Signed Exchanges came up. This is a really neat idea (that’s been around for a while); however, a lot of it depends on the user experience in the browser. Users cannot be expected to know the technical details to get (or understand) the benefits—and we must be wary of some major drawbacks like the cache site seeing the traffic instead the origin.

New comment by rwoll in "Ask HN: Thoughts on new GitHub layout?"

rwoll — Wed, 24 Jun 2020 00:14:05 +0000

I’d second this. In fact, I think the README should be the first thing (potentially in collapsible form so you can easily see the file list without scrolling too much).

Intuitively, I’d bet most people landing on the front page of a repo are consumers of the library looking for a README with info on how to get started or where to look for information on how to get started. Again, this is only intuition—no data to back it up. Project maintainers are most likely interacting with the issues and PR sections or code on the command line.

Ask HN: Why is my healthcare data not more protected? Epic Systems installs

rwoll — Sat, 13 Jun 2020 17:54:19 +0000

Many major healthcare providers use Epic Systems (https://www.epic.com/) software to manage patient records. At about half a dozen independent institutions, I’ve watched receptionists and Drs go from logging in to Epic (which contains all my and other patients health records, clinician notes, test results, etc.) to Facebook or email or general internet browsing. This smells and seems to be one phishKit or rootkit away from putting people’s health data at risk.

Why are these systems not airgapped or at least run on dedicated, restricted devices and networks that only allows Epic Systems activities?!

> You are right, but talking about whether to use k8s or not would make the article 2-3x longer. It is a totally different topic.

Sorry—my comment was written poorly. I think the article is good as is and agree k8s or not is a different topic. My comment intended to be a reminder for all of us reading it that we should ask more questions before choosing a technology.

I’ve found a trend in engineering (including with myself), we sometimes forget to take a step back and see the forest.
