> We recognize that certain social media platforms provide alternative experiences to Twitter, and allow users to post content to Twitter from these platforms. In general, any type of cross-posting to our platform is not in violation of this policy, even from the prohibited sites listed above.

This looks like a cross post from John Carmack's Facebook post, which is not in violation.

oplav··on Layoffs at Twitter on Elon Musk
It is unlikely that at least one of the people in the cited tweet was actually a Twitter employee: https://twitter.com/WealthyCFO/status/1586053744269340672
oplav··on Patients can now access all their health records digitally
I've had routine MRIs for the last couple years and it has been interesting to see how the story to obtain image CDs has changed over the years.

Years ago, I could just ask the tech to burn me a CD and it was often ready for me when I left the changing room. Then I had to start asking the reception desk but sometimes wasn't able to pick it up the same day. Most recently, the reception desk said they could no longer help me and gave me a flyer that said I had to call a central office of the hospital and schedule a CD pick up at a different location. The flyer also made it sound like I was going to be charged for the CD, but luckily I was not.

oplav··on Tool beeps every time data is sent to Google
This is also really useful if you need to mute a Zoom call if you need to listen to something else (like an unrelated video). You can just temporarily set the Zoom audio output to the BlackHole device.
oplav··on Show HN: Browse HN Together in Three.js
Interesting! I've been using webrtcbin for some production work but it's been broadcasting of low latent internally used video with no user input back. I've seen demos of user input with webrtcbin, but have never done it in practice. If you can, do you mind sharing why webrtcbin wasn't a good fit for you (or why MediaSoup was better)?
oplav··on Show HN: Browse HN Together in Three.js
Very cool! Is gstreamer used end to end? Mostly curious if you are using CEF (via cefsrc) and webrtcbin, or if you handled the input and output differently.
oplav··on Ask HN: How to find a small town to relocate for remote work?
+1. I currently live in a college town like you describe (land grant public university, surrounded by farmland). The “downtown” is vibrant. The university draws a lot of international students so cuisine and culture are diverse. Housing is cheap.
oplav··on Someone is impersonating us in a recruiting scam
I was on a Zoom interview panel where it was clear that the interviewee had someone else on an earpiece and was being fed answers.

When we conversed about non-technical things, the interviewee spoke clearly and fluently. But when we'd ask a targeted technical follow-up to something on their resume, they would always repeat the question slowly, and then robotically with several pauses say their answer back. Another interviewer said they could hear the voice in the earpiece talking in between their pauses.

I'm not sure what their end goal was with getting hired, but we ended up cutting the panel short.

oplav··on Robertson vs. Torx screw drives (2021)
All the pocket screws I’ve bought (mostly Kreg brand) have been Robertson. That’s the only time I really see them in the US.
oplav··on Apple and MLS to present all MLS matches for 10 years, beginning in 2023
Leagues, like the NBA and MLB, sell in-market broadcast rights to regional sports networks (an RSN), which gives the RSN exclusive rights to broadcast that game to in-market users. These RSNs typically only show their broadcast through cable packages, which is why local users would need to subscribe to cable packages that carry the RSN that holds the rights to their local team. However, some RSNs (at least in baseball) are starting to build direct to consumer streaming products. NESN, the RSN that carries the Boston Red Sox, has come out with NESN 360 which allows users to stream Red Sox games without a cable package at a price point of $30/month [1].

Leagues retain out-of-market broadcast rights and serve those to out of market users through their streaming platforms like MLB.tv and NBA League Pass.

oplav··on Ex-Google Tech Lead Brags About How He Used to Trash Women's Résumés (2022)
I've stumbled across this person's YouTube videos before. For some reason, I always assumed he was a troll with how much he leans into "ex-Google tech lead".
oplav··on FAA says 5G could impact radio altimeters on most Boeing 737s
Very anecdotal, but a flight my wife was on 3 weeks ago returned to the terminal before takeoff and had to switch planes because of an altimeter malfunction. The pilot cited it was because people didn’t turn off airplane mode.

oplav··on Slack System Status
Slack has been struggling for my workspace the last 10 minutes. Can still get messages through (sometimes) but threads won't load at all.
oplav··on GStreamer 1.20: Embedded and WebRTC lead the way
I'm not the commenter you are responding to, but we've been using webrtcbin in a production system since late 2019. We had some help from Collabora's consulting services (specifically from Olivier and Aaron!) and our use case was pretty targeted (near real time broadcasting of a video stream to a handful of internal users) so YMMV.

EDIT: Didn't realize you were the author of Pion! We looked at Pion and Janus when we were evaluating, but ended up using GStreamer ultimately because we had other GStreamer components within our pipeline.

There are some hacks to work around it though.

It sounds like a git joke about squashing vs merging.
oplav··on Ask HN: Who is hiring? (February 2022)
Major League Baseball (MLB) | Senior Full Stack Engineer | NYC or SF | https://www.mlb.com/careers/opportunities?gh_jid=3786700

We are looking for a software engineer who enjoys solving data problems using visual tools primarily aimed for web (eg. d3, three.js, WebGL, etc). Given that it's MLB, the domain is primarily baseball! But we do tackle problems in interesting technology domains, like video processing and camera projection.

Our latest project is currently working on animating real time skeletal data: https://mlb.com/news/fieldvision-plays

oplav··on Docker for Mac Without Docker Desktop
I've been exploring 2 alternatives (podman and colima) to replace my normal docker workflow, which is just building and running containers locally, sometimes with docker-compose. I started with podman but had issues with 2 main pieces of my workflow: docker-compose (or podman-compose) and shared volumes (with `run -v`). Switched over to colima and those worked out of the box for me ("brew install docker; brew install docker-compose; brew install colima; colima start; docker run ...")

oplav··on FalsiScan: Make it look like a PDF has been hand signed and scanned
I have, in the past but not recently, run into situations where I need to visually sign something, and the form was rejected when I digitally signed it with MacOS Preview because they required the form be printed, signed, and re-scanned.

This would be helpful in that case.

oplav··on Ask HN: Did you deliberatively develop any new hobby in recent years?
Similar experience with woodworking. During the pandemic, I ended up doing a lot of work on a relative’s farm (eg. installing fence posts, building new barn doors, turning an old boat trailer into a utility trailer). Not only did I enjoy working with my hands, it was refreshing to not be able to Ctrl+Z mistakes away.

Since then, started acquiring tools to pursue woodworking at home and am really enjoying it. I also find myself going down YouTube woodworking rabbit holes often.

oplav··on Show HN: We open sourced our new Mac developer setup script

  defaults write com.apple.finder ShowPathbar -bool true
This is handy. I could never figure out how to reliably use a Finder window to navigate to a specific directory so I resorted to running "open ." from the directory in the terminal.
oplav··on Ask HN: Long-form info-dense videos on YouTube you would recommend to anyone?
Tony Zhou and Taylor Ramos (of Every Frame A Painting) are involved with Netflix's new show Voir, which seems to follow the same video essay format. Haven't watched it yet, but it's on my list.

oplav··on Fundamentals of Piano Practice
I agree with this. Scales more or less have an accepted fingering so if you practice these a lot, you'll gain some natural muscle intuition for when you see variations on scales and arpeggios in the wild.

When I took classical piano lessons, each week we'd have a new key assignment and we'd have to practice scales, chords, and arpeggios in that key.

My piano teacher hand crafted a very nice sheet that listed all scale and arpeggio fingering for all keys, but that is buried somewhere in storage. This website [1] seems to have the same info.
