matmatmatmat··on Thunderbird for Android preview: Modern message redesign
Hm? We sync our calendars using Nextcloud, but admittedly, that's not everyone's cup of tea.
matmatmatmat··on Redfin cuts 13% of staff, shuts down home-flipping business
The interest rate is, yes. The monthly payment, no.
matmatmatmat··on Starlink Aviation
Starlink promises 350 Mb/s, not MB/s, although given their current promises vs actual speeds, I think customers may adjust their expectations a bit.

Not sure where you pulled 30 Mb/s for Viasat service but it regularly tests more than 2x as fast as that (on the current-gen satellites, the newest of which is 5 years-old by now. Viasat-3 Americas has actually over 5x the capacity of Viasat-2 along with a big bag of other goodies that will enable a class of service heretofore unseen.)

I regularly videoconference with team members who are on geostationary Viasat..., it's just not an issue. They say they had to learn how to adapt a little bit by giving people time to finish their thoughts, that's about it.
matmatmatmat··on Starlink Aviation
I've done paid work on an airplane WiFi connection through Viasat and really did not find the latency to be an issue at all, including working in the terminal.

No doubt everyone has different experiences and tolerance levels for latency, but, really, I think the latency issue is vastly overblown.

I don't have any sympathy for CERN and neither do they have any for their employees. The people that run CERN are entirely focused on a particular path of scientific progress and their handling of the situation will only change if they can't find people to do the work that needs to be done.

An article like this is a nice alarm bell that maybe they should reconsider their approach, but nothing will really change until it impacts their bottom line, which is getting correct work done on a timely schedule.

That said, I think it's fair to say particle physics hasn't had any major discoveries since the Higgs and no sure-fire theoretical path toward one, either, so the best and brightest may start looking at other fields.

I'm not sure this is much of a counterbalance? I think you can generally expect junior positions to have less responsibility and stress, at the expense of virtually no chance of moving up unless you really, really grind, and even then, there's not a lot of space at CERN. I think you really have to love it to the exclusion of all else and be smarter than your already smart peers to succeed there.
matmatmatmat··on Quiet Quitting
Yeah, you got a great deal. I've been hearing this story at least since I worked there, about 15 years ago.
matmatmatmat··on Quiet Quitting
Maybe I should've been clearer, but I didn't mean personal effects at work. The people I knew had not even unpacked their things in the apartments they were renting because they were too busy working, particularly professors.

And this applied to both tenured and untenured professors. Don't want to name names but one of the high up profs I chatted with there worked roughly 60 hours a week, 6 10-hour days. I mean, he loved it, and he had a lot of responsibility, but I think it's fair to say it's pretty much all he did. His wife mostly traveled and his daughter was already in undergrad by then.

It is genuinely unclear to me how a new prof could hope to compete with that or make a meaningful contribution when even the "old guard" have given up everything to just work.

It's interesting to see this from CERN, which is essentially an institution that enables young people to work unlimited hours for next to no pay and virtually no chance of ever attaining significant recognition of their work.

In my brief time there, it was not uncommon to hear stories of people who had moved there and not even unpacked all of their belongings after a year or more.

On the plus side, if you love particle physics and/or the surrounding context, it's one of the best places to be. On the minus side, you'll have to give up everything else and be quite smart in addition to move ahead.

matmatmatmat··on Machine learning, concluded: Did no-code tools beat manual analysis?
In line with the other comments, let me give you a recent example from my work.

We had a dataset with just about 30 records and about twice as many features, about 1:3 class balance between positive and negative. Not an impossible situation at all, but there was a big premium on performance, so we threw the book at it.

Lo and behold, SVM with some particular parameters comes out on top. Ship it, right?

Not so fast, what decision did the model learn? Turns out, the model was learning decision boundaries that did not make sense. It was overfitting because the model did not know about what kinds of decision boundaries were allowable.

In the end, someone looked at a 2D scatter plot, drew a line and called it a day. It took a fraction of the effort and time of running through a box of models. It'll save the company $MM and it's trivially explainable to engineers and execs.

AutoML with blind application would've completely botched this.

I look forward to seeing what will be able to beat AWS in the long run. I don't know what it could be. I guess, maybe, if they stop innovating in the space others will catch up and then price will become the differentiator?

Idk, right now AWS is a money printing machine.

Could you expand a bit about what kind of information class imbalance can reveal?

Whether deliberately or not, yes.

Physics PhD from about 7 years ago. My impressions are the same as yours.
matmatmatmat··on Ask HN: Been writing code for 40 years and can't get hired
I have this same mindset and the same plan: Keep working, and keep learning. Do you have any insight from your many decades of experience that you would like to share? I would appreciate it.

Looking forward to the results of your work, good luck and thank you!

Seriously, can it get much better than this?
matmatmatmat··on What’s harder to find than microchips? The equipment that makes them
ASML recently sent out a memo about "low retention."
matmatmatmat··on Zillow to stop flipping homes, loses more than $550M, lays off 25% of staff
About that last point, Redfin has access to the regional MLSs. I imagine they have a more complete dataset.

My understanding is that Zillow relies on realtors to add their listings, so that means, maybe-it-happens, maybe-it-doesn't, entry errors, maybe-it's-updated, maybe-it's not...

matmatmatmat··on Zillow to stop flipping homes, loses more than $550M, lays off 25% of staff
It's unclear to me how much visibility Zillow really had, since, AFAIK, they don't have access to MLSs in the areas where they buy and sell.
matmatmatmat··on Leaving Debian
Just like any other complex, tightly-integrated system, systemd had its share of bugs, quirks, and new ways of doing things that forced people to change. It's not hard to imagine why it faced some resistance.

Eh, it's been a while now, though, and I guess most of that has gotten worked out.

matmatmatmat··on Leaving Debian
10x this. Install it. Set autoupdates. Come back in 3 years when it's time to think about upgrading to the next major release. Maybe don't upgrade, because, why? Everything works. I just want to keep things working.

To be honest, Desktops reached their peak for me with Gnome 2. I'm using MATE and I'm good.

matmatmatmat··on Mihály Csíkszentmihályi has died
HN readers in Hungary are just waking up to this news, but I can confirm that's a pretty decent approximation.

Significantly lower. Agriculture accounts for about 5/6th of CA's water usage for a sector that generates 2% of its GDP.

To be clear, I love getting my food from the Central Valley, but I also think there are overdue discussions to be had about where the water's going and how much utility we're getting from it.

Do you have a detailed write-up of this somewhere? I would be interested in reading it.
matmatmatmat··on Europe’s energy crisis is about to go global as gas prices soar
Thanks for your thoughtful reply. I'm obviously a bit late with this, but I wanted to add that I'm not sure how much of a deterrent gas routes through other countries were for Russia to begin with, e.g., it did not seem to help Ukraine much.

Desal gets tricky quickly. Already at current scales, the brine discharged back into the ocean causes dead zones.

Would be great to get your thoughts on climate change when you get the chance.
