I think a lot of companies view their free plan as recruiting/advertising — if you use TailScale personally and have a great experience then you’ll bring in business by advocating for it at work.

Of course it could go either way, and I don’t rely on TailScale (it’s my “backup” VPN to my home network)… we’ll see, I guess.

Let’s see Stephan Miller’s card…

States != cities, e.g., https://underscoresf.com/heres-what-you-make-as-a-low-income-earner-in-san-francisco/

If you own own a modest place (<2000 square feet) in a decent (not “old money”) neighborhood in San Francisco and have kids, I would be shocked if your household income isn’t $350k+/year. If that’s considered “upper class” then it’s a very sad statement about how standards of living have degraded — this is likely comfortable living but it is not exotic car + first class airfare money. And it’s almost certainly “less house” than you’d like.

And unless you inherited a lot, you definitely need to keep working to afford that modest lifestyle.

That claims ~$420k compensation with ~$25k “other.” If he is playing any substantial role in bringing in $100M+ funds for a good cause, I’d say this person’s compensation isn’t something I’m going to get worked up about. For VHCOL areas this is middle class household income (looks like they’re based in NY NY, so…VHCOL).

I’m too lazy to verify my hunch, but I’m guessing Texas is largely oil (exploiting natural resources), whereas California is largely intellectual output (tech, with some Hollywood and other sundry stuff), though California certainly does exploit its natural resources too (good farming conditions, some oil…).

Yep, you’re right — I was just responding to parent’s comment about fiber being best because nothing is faster than light :)

That’s…not really a cogent argument.

Satellites connect to ground using radio/microwave (or even laser), all of which are electromagnetic radiation and travel at the speed of light (in vacuum).

Light in a fiber travels much more slowly than in vacuum — light in fiber travels at around 67% the speed of light in vacuum (depends on the fiber). In contrast, signals through cat7 twisted pair (Ethernet) can be north of 75%, and coaxial cable can be north of 80% (even higher for air dielectric). Note that these are all carrying electromagnetic waves, they’re just a) not in free space and b) generally not optical frequency, so we don’t call them light, but they are still governed by the same equations and limitations.

If you want to get signals from point A to point B fastest (lowest latency), you don’t use fiber, you probably use microwaves: https://arstechnica.com/information-technology/2016/11/private-microwave-networks-financial-hft/

Finally, the reason fiber is so good is complicated, but has to do with the fact that “physics bandwidth” tends to care about fractional bandwidth (“delta frequency divided by frequency”), whereas “information bandwidth” cares about absolute bandwidth (“delta frequency”), all else being equal (looking at you, SNR). Fiber uses optical frequencies, which can be hundreds of THz — so a tiny fractional bandwidth is a huge absolute bandwidth.

80% of the USA lives within urban areas (source). Urban “fiberization” is absolutely within reach.

Agree that running fiber out to very remote areas is tricky, but even then it’s probably not prohibitive for all but the most remote locations.

So the irony is

I see what you did there…

I think you mean more scrupulous, not less.

Hopefully you can publish in an open-access journal — if not it would be great if you could share an arXiv preprint :)

It is really powerful per watt, and has a built-in UPS. Any homelab type things you could do with that? macOS+homebrew will give you a nice *NIX feel, very familiar if you’re a Linux user.

I’m a fan of having a remote homelab computer+disk for off-site storage. This would be a good candidate in that it wouldn’t use excessive power at a friend/family’s place, but may be overkill (I use a pi3 for that).

Physics is like sex: sure, it may give some practical results, but that’s not why we do it.

I think the same is true for a lot of folks and self hosting. Sure, having data in our own hands is great, and yes avoiding vendor lock-in is nice. But at the end of the day, it’s nice to have computers seem “fun” again.

At least, that’s my perspective.

Hobby 1: Ballroom dancing

No I’m pretty sure Strictly Ballroom is a completely accurate portrayal of ballroom dancing.

Whatever you decide for your laptop, I’m a proponent of a barebones off-site setup if you’re trying for 3-2-1 backup or similar.

I use a raspberry pi 3 with a single HD (ZFS) retaining some number of daily/weekly/monthly snapshots. Daily rsync, everything over WireGuard+VPS (TailScale would work too).

From our experience in the US, the birth is nothing compared to the financial drain of the other expenses. And at this age, childcare dwarfs all the other child-related expenses.

We have great insurance and don’t rely on family for childcare though, so the math is very very different for someone with “free” familial childcare and no/lousy insurance…

Others mentioned virtualization — I have had issues with COW filesystems (btrfs), as COW does not always play nicely with VM drives (extreme fragmentation and very poor performance).

I don’t know how compensation works in academic administration, but if there’s any vesting going on then you could “take a pay cut” but end up making more due to previous compensation vesting.

Certainly possible for public companies, but again, unsure if that could be the case for a university president…
