mapmeld··on Ask HN: Has anyone here ever tried throwing everything away?
For years I did month-to-month Airbnbs to chase these feelings around being able to pick up and move wherever, whenever. If you can do WFH and have financial security, I would say sell some stuff, put the rest in storage, and make a plan to come back to your starting point in 6-12 months. You might just need to process things. A lot of people who move to Alaska or Hawaii to "get away" end up learning about themselves, and that's good.

If you don't have that flexibility, yes it's tricky to move to a new city. Get hired first if possible. Set realistic expectations for yourself (e.g. I will go to some Meetups and grow basil, NOT I will become the best _ in NYC and meet my BFF in the building). That's something a therapist or life coach type can help with, too.

mapmeld··on Grabby Aliens (2021)
My go-to counterargument for this is that galaxies are really far apart (from us to Andromeda is 25x the diameter of the Milky Way). If you haven't developed FTL travel, it's a long haul with very little benefit on the way.
mapmeld··on Bayesians moving from defense to offense
I went to a week-long Probabilistic AI seminar, and I got the impression there was an era when enough stats and math professors did not take a Bayesian framework seriously, that there was a risk someone's thesis or dissertation defense would be derailed by someone on faculty.
mapmeld··on Ask HN: How are quantum computing companies making money?
I believe it's quantum annealing. Not a physicist but my understanding was it can be used for some problems but not universal quantum computing.
mapmeld··on Ask HN: How are quantum computing companies making money?
IBM, D-Wave, and others have press releases about consulting and R&D partnerships. For example, Volkswagen: https://www.vw.com/en/newsroom/future-of-mobility/quantum-co...

TBH it doesn't seem practical - I don't know if this was to boost VW's image or to retain researchers and management (consider how much Facebook gave David Marcus to think about Libra for a couple years). But if you're the quantum hardware provider / SaaS then you'll take the call.

mapmeld··on She lived in a New York hotel for more than 40 years, but her life was a mystery
Everyone has kinda answered your question about these old practices carrying over. We're seeing the end of the last surviving hotel residents - recently NYT covered the eviction of an 82-year-old, who took over a contract from his aunt https://www.nytimes.com/2023/05/08/nyregion/stewart-hotel-lo...

Nikola Tesla famously died in his residential room at the New Yorker Hotel, and I recently learned that after his presidency, Herbert Hoover lived at the Waldolf Astoria for 30 years.

mapmeld··on Future is quantum: universities look to train engineers for an emerging industry
I wrote some quantum library code, ended up interviewing with 2 quantum startups and Amazon's lab at CalTech

For people who've been in the industry for a while, the past 5 years have been amazing - (small, noisy = NISQ) quantum computers are real, there's VC and government money in it. Aside from the industries you mentioned, there's interest in chemistry and medicine (for example: https://www.proteinqure.com ) and you can work with smart people. Edit: should also mention post-quantum encryption research which is adjacent to this space and in practice at Google, Cloudflare, Microsoft.

That said, if I joined a quantum company 2-5 years ago and worked long startup hours, I could be disappointed that it's not practical yet, and ML / NLP has taken off. So it's up to you what your alternatives are and what seems like a "win".

mapmeld··on Kurdish Parentheses on OpenStreetMap, Three Ways
I did a write-up because it was an example of broken text "in the wild" rather than in technical references. Also it takes me a minute to think of () as open/close parens instead of left/right parens.
mapmeld··on Kart: DVC for geospatial and tabular data. Git for GIS
Having worked on a Geogig-as-a-Service proof-of-concept for a moment in time, the problems there were: no way to see commits and changes on a map (GitHub's later addition of a GeoJSON view and diff map being the final knell), and no server to host your repos (i.e. you would host your own Java/Maven server). The word was that a big government or military customer wanted this technology and didn't need any of that consumer-facing stuff, so the open source aspect was more of a "let's see if it catches on".

My project never took off because it was my first cloud and Maven project, but it was fun to tinker with the idea until GitHub got around to its GeoJSON stuff.

mapmeld··on Sam Bankman-Fried testifies, says he "skimmed over" FTX terms of service
No, in the same way lawyers and the judge can decide ahead of time not to admit an unqualified expert witness, or to dismiss the jury for someone like Darrell Brooks representing himself by bringing up irrelevant information and hearsay which is inadmissible in court. If someone says the wrong thing in front of the jury it is somewhat difficult to erase it from their brains or to convene a new jury.
mapmeld··on Cold war satellite images reveal unknown Roman forts
Somewhat; Tim Traveler recently visited a 5,000-year-old dolmen in France, and it's preserved, but treated like any other small roadside attraction https://www.youtube.com/watch?v=1S6wP8ox1R4
mapmeld··on Ask HN: How long until quantum computers break 512 bit RSA/ECDSA? 1024 bit?
I agree with "many many years" but a good number of quantum computers use other methods (superconducting qubits from Google/Rigetti, or trapped ions from IonQ). They have much smaller numbers of qubits, are more generally applicable to problems, but have the issue of noisy readings.
mapmeld··on Thirteen years later, why are most administrators still from 2005?
I'd encourage people to keep editing. From HN and Reddit I thought that my changes would be thrown out, but nothing happened except bots cleaning up my references.

An issue that I noticed is that scientific articles accumulate newsworthy theories. The prion article has a section on weaponization, and prion diseases often have sections on alternate theories, or say that the causes remain unknown. Years later these articles need to be updated or trimmed down.

mapmeld··on Montana loses fight against youth climate activists in landmark ruling
Yes, it's in the state constitution, Article IX https://courts.mt.gov/external/library/docs/72constit.pdf
mapmeld··on Tracking the Fake GitHub Star Black Market
GitHub gradually removes these users as they catch up to them, so not helpful to have extra steps. I have a couple of repos which were briefly popular, so when a new user stars it today, and I see 1000s of other stars, it's suspicious and I get a peek into their world.

There are obvious numeric usernames, but also fake orgs with repos for the users to fork and interact with, and a few account takeovers (i.e. someone had signed up for GitHub in 2015 to make a free wedding website, abandoned it, and the account fell into spammer hands). These used to be easier to report.

mapmeld··on American Airlines jet and shuttle bus collide on taxiway
I follow a YouTube channel (VASAviation) which posts notable ATC recordings. JFK, AUS, and this collision are unusual in a short period of time. In 2017 there was a similar "trend" including two Air Canada incidents at SFO, which seemed like a lot for one airline and one airport? Most likely these are uncommon but any commonality or closeness in that randomness seems like cause for a person to change their perception of how likely it is.
mapmeld··on Ask HN: What is the best podcast you listened to in 2022?
If you like mysteries, The Strait Times did a mini-series on "The Unsolved Mysteries of South East Asia" [0] which were (other than MH 370) totally new to me.

"Arms Control Wonk" [1] has episodes on North Korea missile tests, open source intel methods, etc. which often get simplified by regular press.

mapmeld··on Ask HN: How is the job search coming along for people who got laid off?
I'll add to the Amazon interview complaints (early 2021 so remote). The recruiter prepped me ahead of time that I would have only 4 interviewers, and the next day they would be sending me an approval or some feedback. Having done interviews before I knew this was nonsense, and sure enough 2 or 3 days after my five calls, he called back genuinely surprised that there was no feedback. The interview itself was genuinely interesting but complicated by this team not having hired a frontend eng before.
mapmeld··on Reasons why Fortran is still used (2021)
As an open source dev, I was impressed by how patient everyone is in getting complex Fortran PRs merged (you can take a look on OpenBLAS on GitHub). Part of this is the communities which still use Fortran, and part of it is no one is doing it haphazardly. I even got good suggestions on my own repo from strangers.
mapmeld··on Someone is pretending to be me
Bizarre. I (US-based engineer with an Upwork account) was invited into a less sophisticated variant of the scam in spring 2021:

> Nice to meet you. I am looking for a US person who do business with me. You can earn money with a few cooperation. Do you know Upwork or Toptal site?

They also had the text of the message in a GitHub repo. I tried reporting them to GitHub, Upwork, and Toptal, but I don't think they knew what to do with it? I assumed my scammer was looking to evade banking rules or sanctions, but it could be for either fake employment or actual work with a US-based persona like in this case.

mapmeld··on Tell HN: Sudden Chile daylight savings time rules change causes chaos
The schedule of Ramadan (the Islamic calendar month) may be delayed or extended in countries which use a physical sighting of the crescent moon to end the month, and can even differ by country if they go to different astronomers. This wouldnt affect DST I think, but more the timezone info - database. https://www.reuters.com/article/us-europe-islam-ramadan-idUS... https://www.economist.com/the-economist-explains/2018/06/12/...
mapmeld··on Google Trying to Solve a UUID
This reminds me of a story of a geocoder (postal address search) which was found to frequently fail in NYC. When they debugged, they found addresses in east Manhattan (e.g. 100 E 61 St) were being converted to scientific notation.
mapmeld··on US regulators will certify first small nuclear reactor design
Yes. When I attended an IAEA Safeguards conference in 2018, there were a number of these civilian nuclear battery designs but none had been built. A small nuclear battery can replace building-size diesel generators which remote communities and islands, data centers, etc. currently use as a primary or backup power source.
mapmeld··on Openstreetmap, a global map for worldwide insight
Is this an https://openstreetmap.in issue or Crimea or ?
mapmeld··on It’s Time to Build
Not a subscriber to this view, but the concept is that we take care for our family and friends for free, and charity is driven by showing us real people rather than cold facts. For the rest of the "people we don't know", investment and payments are capitalism's way of helping them out.

In this context, it sounds like he's surprised that investors are waiting for government to bail out any normally-profitable airlines, rather than making an investment or buying in while keeping them afloat. This seems simplistic to me; the cost of maintaining an airline or hotel for the upcoming no-revenue months is so high that your investment would be lost.

mapmeld··on OpenTable Restaurant Performance Data
When I saw drops on Mondays, I initially thought it was due to a year-on-year weekday mismatch, but the analysis is sound

> For year-on-year comparisons by day, we compare to the same day of week from the same week in the previous year. For example, we'd compare Tuesday of week 11 in 2020 to Tuesday of week 11 in 2019.

Interesting that most have a double dip, with a big drop on 3/2 and then again on 3/9 which is ongoing

mapmeld··on Human reproductive cloning: The curious incident of the dog in the night-time
Outside of governments making their own WMDs against international rules, the closest would have to be Aum Shinrikyo. Before their sarin attack in Tokyo, they also manufactured VX gas, recruited scientists from different fields, and conducted experiments in the Australian Outback. There is a more farfetched conspiracy that they used the remoteness to test a nuclear bomb ( https://en.wikipedia.org/wiki/Banjawarn_Station ).
mapmeld··on Fortran.io – a Fortran Web Framework
I did get a patch some time ago which was really well-written. Almost all pull requests to serious Fortran projects (mostly OpenBLAS) get merged in. I wrote about it here: https://medium.com/@mapmeld/fortran-culture-on-github-a257dd...
mapmeld··on Fortran.io – a Fortran Web Framework
I couldn't remember, but checked - I am replacing ' with _ in the actual code https://github.com/mapmeld/fortran-machine/blob/master/marsu...
