planewave··on Strata – An app that talks me out of dying outdoors
I’m not so sure mocking is really that on point, a tool used to understand avalanche safety should be safe. The product copy highlights safety and the value of providing a recommendation instead of having to collate and synthesize different data yourself.

Avalanche risk and its management are unknown to me, but not to ski patrols, experienced backcountry trekkers, scientists, and national weather services of many countries, etc. I saw no evidence of trials to test to see how the technology performs against real conditions.

If you can’t trust this product’s recommendations within some margin of safety then it’s value proposition disappears.

Why not market it instead as an experiment and seek some way of collecting data to improve the process or develop a model fine tuned to the inputs?

planewave··on Strata – An app that talks me out of dying outdoors
Is it just me, or does it seem extremely dangerous to market: “Strata doesn't just show the data. It makes the call.”

The page states it’s powered by Claude with nothing I could see that relates to its performance, metrics, processes, testing, etc. for something expected to be used in a safety application.

planewave··on Tell HN: Azure outage
Azure Network Availability Issues

Starting at approximately 16:00 UTC, we began experiencing Azure Front Door issues resulting in a loss of availability of some services. We suspect that an inadvertent configuration change as the trigger event for this issue. We are taking two concurrent actions where we are blocking all changes to the AFD services and at the same time rolling back to our last known good state.

We have failed the portal away from Azure Front Door (AFD) to mitigate the portal access issues. Customers should be able to access the Azure management portal directly.

We do not have an ETA for when the rollback will be completed, but we will update this communication within 30 minutes or when we have an update.

planewave··on Tell HN: Azure outage
yes, and it seems that at least for some login.microsoftonline.com is down too, which is part of the Entra login / SSO flow.
planewave··on Tell HN: Azure outage
It is interesting to see the differential across different tenants in different geographies:

- on a US tenant I am unable to access login.microsoftonline.com and the login flow stalls on any SSO authentication attempt.

- on a European tenant, probably germany-west, I am able to login and access the Azure portal.

planewave··on Phased Array Microphone (2023)
Would this also be true for electrostatic speakers as well? Though would probably would require greater gain/amplification or, potentially the application of some kind of bias voltage for the capacitive diaphragm of the speaker.

Just speculation based on the shared operating principal with condenser microphones

planewave··on Teach yourself to echolocate (2018)
This comment captures a lot of important detail about echolocation.
planewave··on Apple put the Magic Mouse's charging port on the bottom again
Or possibly, this was the smallest tool change possible. Saving costs by not having to redesign parts like the glass, etc.

Many embedded systems use SWupdate to manage this, which can hook into uboot.

Data warehouse, even data lake, I can imagine a meaning for. Without context, what is a lakehouse?
planewave··on How one ED mobilized his department during a mass casualty incident (2017)
These are core principles that are taught to Emergency Managers in the Swarm Leadership method [0].

  Unity of mission – it was for these leaders, Save Lives!

  Generosity of spirit and action – these leaders and people across the community were willing and eager to help one another.

  Stay in your lanes, doing your job, and help others to succeed in theirs. How can I make you a success?

  No ego – no blame. No one took credit for their success together. No one pointed fingers when problems arose.

  A foundation of trusting relations – these leaders knew and had confidence in one another.

I might recommend sending to the landing page or a description, I am not sure how many folks will install a TestFlight without more information.
planewave··on Azure DevOps is down globally
No, from the documentation it seems they share a lot of infrastructure between GitHub Actions and Azure DevOps pipelines.

My web interface and pipelines appear to be down, but it seems like git operations are still working.
planewave··on Ask HN: Where are the good resources for learning audio processing?
Second anything from CCRMA, the inventors of FM synthesis and still the one top programs in the country/world.
planewave··on Ask HN: Where are the good resources for learning audio processing?
Professor Puckett, inventor of Max and PureData (the two top visual programming languages for DSP) has a book, The Theory and Practice of Electronic Music, with interactive examples written in PD, this one probably has an example exercise for a pitch shifter [0]

I often recommend also Music and Computers originally out of Columbia. [1]

planewave··on Podman Desktop 1.11: Light mode, Kubernetes features, macOS improvements
Yes! Maybe I’m always expecting the wrong thing with Podman Desktop, but I can’t ever get it to work the way I expect it to - on Windows or Mac.

Rancher Desktop, however, has been a breeze. Same with using Lima.[0]

This is just called sibilance [0], it’s most likely in the source material but could be accentuated by a number of downstream factors.

planewave··on Doug Engelbart’s 1968 demo
I met Mr. Engelbart once as a child when my mother worked at SRI in the 90s/early 2000s. At the time I had seen the mouse prototype while wandering the halls and on some open house day I was introduced to him. He listened to me, a young kid, talk excitedly about technology for what must've been awhile and was very encouraging and kind. While I was excited about computers at the time I had no idea the significance of his ideas until I was an adult.

Looking back on it, I am awed by the kindness he showed to some random kid.

planewave··on With Layoffs, NPR becomes latest media outlet to cut jobs
The way to do this is just to become a member of one of NPR’s member stations, which provide the network its main source of funding (with the Corporation for Public Broadcasting being a distant second, IIRC). The member stations are also responsible for creating much of the content distributed by the network, though National NPR in DC produces the major drive-time news shows (Morning Edition and All Things Considered).
planewave··on TSA now wants to scan your face at security. Here are your rights
I did, the agent tried to tell me that I had to use the facial recognition system. I pointed at the clear sign which said it was optional. She called a supervisor and they checked my ID as normal.

I fly often for work and have only seen this once out in the wild.

Besides having to insist that it was optional, there was no additional screening necessary.

planewave··on Extracting Audio from Visual Information
Theremin (yes, the same) invented a device using an infrared beam directed at windows which was able to capture speech from inside. [1] This is separate from his RF powered Thing bug that was installed in the US Embassy in Moscow. [2]

Similar techniques have been shown using lasers vibrometers to achieve a similar effect.

Both of these are perhaps not visual in the same way as this method in the article. But, do illustrate the long history of non-traditional microphone eavesdropping techniques.

planewave··on How San Francisco Broke America’s Heart
Perhaps this is naive, but also as someone who grew up in the bay (south bay specifically) it feels like after the crash of 2001, and the resurgence of tech after that, the culture took on a markedly different tone. I guess perhaps in the transition from silicon dominance to web dominance something felt like it was lost in the valley.
