athenot··on Making Your Connection Bad
On macOS one can use the traffic shaper dummynet(4), controlled with the dnctl(8) command, which has a nice man page that describes it.

It's always surprising to see how apps degrade under high latency connections and is a good way to test how users will actually experience things in less-than-ideal conditions.

athenot··on Salmon return to lay eggs in historic habitat after dam removal project
"Dislike" may be an anthropomorphism. Perhaps it's more of an opportunity for the beavers, since dams are their habitat and provide a food source for them.
athenot··on How do you deploy in 10 seconds?
This isn't really that far from using Ansible to deploy. Effectively logging into X servers all at once and editing the things. This can be a valid strategy.
athenot··on Why TCP needs 3 handshakes
I believe that's UDP. :)
athenot··on Streaming every NFL game this season requires 7 different services, costs $2,500
This is more expensive than actual season tickets to every game for a team.

(Yes for 1 person, whereas TV can be watched by a group; but still it's crazy expensive.)

athenot··on Marketing to Engineers (2001)
This is generalizable to "know your audience" and "meet people where they are at".

Generic sales people who are good at appealing to the emotional in their target demographic will only go so far when the audience is specialized in a field. That's not to say those people are completely immune to emotional tricks. But if that's the only way the salesperson tries to connect, they will have a hard time getting through.

I'm not a salesperson but I witnessed a coworker who was insanely good at selling our Healthcare SaaS product, and the way he connected with his target audience didn't feel sales-y at all. In fact, he genuinely cared about finding a solution for the people he was selling to. He believed in our customers and knew our product was going to help them in their goals—even with the warts & bugs we had.

athenot··on Interviewing the Interviewer: Questions to Uncover a Company's True Culture
Same. I want candidates to ask me questions. If they don't, I prompt them. If they still don't have any questions, that usually counts against them.

Of course, that's because I cultivate teams where I want people to think for themselves, even if that means dissent or arguing with me. I'm not trying to hire a bunch of "yes people" who just make me feel good. And I'm aware that it takes a lot of courage to ask questions or challenge an interviewer, but that's a similar trait that I'm after in the roles I'm usually filling.

athenot··on USPS text scammers duped his wife, so he hacked their operation
We have a lot of progress under the form of STIR/SHAKEN. Now it doesn't prevent all types of spoofing but it makes the calls traceable back to the originating carrier.

What happens is scammers get numbers with small carriers who interconnect with major ones. Eventually the reputable carriers notice spam from these smaller carriers and start dropping their calls (or banning them altogether). So the smaller carriers decide whether they want to see their legitimate traffic dropped or just ban the offending users (which is eventually what ends up happening). Scammers end up hopping to a different carrier so it's a cat-and-mouse game, but it's a lot more expensive to play now than it was with simple number spoofing.

In parallel, numbers are starting to get reputations attached to them, similar to IP addresses. Some filtering takes advantage of that.

Of course, spearfishing can continue unimpeded with someone buying a prepaid cell phone and using that to call a specific target. :(

athenot··on No price Microsoft could pay Apple to use Bing: Google antitrust ruling excerpts
And if you do want their LLM, just append a '?' character after your query. It's up to the users, not forced upon them.
athenot··on Pongamia trees grow where citrus once flourished
Hawaii got rid of all their sugar cane, replacing it with coffee and other higher-value crops.
athenot··on Apple Maps on the web launches in beta
They've added ratings to the Maps app for certain categories of businesses (or maybe it's for businesses not in Yelp, dunno). It looks like they are testing it out. It also supports picture upload.
athenot··on I gave myself a month to make one new friend
> Then came the question of method. The resounding advice was “Get a hobby.” But I had only a month, and I didn’t think I could learn a new skill while trying to make friends.

As she later wrote in the article, it's not necessary to possess a skill to hang out with others, mere interest is often sufficient. Many hobby "tribes" (for a lack of a better word) have plenty of enthusiasts who will be more than happy to welcome a newcomer and show them around. That may be a friendship in of itself, or that may lead to other friendships centered around some common interest.

The deepest of friendships often start in the shallowest of ways, so lowering expectations at the beginning may be useful.

athenot··on Panic at the Job Market
> I don’t know about you, but I care about company structure, product issues, platform scalability and reliability, customer usability, developer usability, performance, legal compliance, security, corporate scalability, and team cohesion all at the same time.

Then he should either be senior management or a high-end consultant (the kind that's well paid and actually listened to, who fixes structural problems in companies). And perhaps some soft-skills would help him to gel better with the people who pay him.

athenot··on AT&T says criminals stole phone records of 'nearly all' customers in data breach
One mitigation is to make your mother's maiden name the output of:

    head -c 20 /dev/random | base64
And keep track of the result in your favorite password manager.

Fortunately, fewer and fewer orgs are using security questions, but there are still some important ones that only use that and no MFA.

athenot··on Deactivating an API, one step at a time
Other strategies that could come in handy before completely shutting down the API:

- Rate-limit the API, with increasing aggressiveness until you're down to 0 requests per unit of time;

- Introduce latency in serving the requests (assuming your edge can handle the increased volume of open connections).

Both of these introduce gradual degradation of the old API, without outright killing the business functionality that recalcitrant customers are nevertheless reliant upon. It helps spur a bit of urgency to switch to the new API, while remaining nice. Many (enterprise) customers will wait until the last minute to switch: essentially they are having to put in work without any tangible feature gain—at least from their perspective.

Regardless of the strategy, one other point I'd add is to monitor actual use of the API; if important customers are still actively using the old API, it would be unwise to shut it off.

athenot··on Etsy: Company escaping 'race to the bottom', getting back to its artisan roots
This could be useful if they allow search filtering. Sometimes I may want something artisanal, other times I may not care much about the artisanal qualities and curated is good enough.
athenot··on Drawing Machines
That's one of them, as mentioned on the site. ;)
athenot··on Road planners embrace the diverging diamond interchange
Yes, though they are close to each other (a bit too close to make a roundabout).

All the ones around where I live are on a single bridge; but they usually need to widen said bridge when they convert the intersection.

athenot··on Road planners embrace the diverging diamond interchange
Original title: When driving on the wrong side of the road is the right way to speed up traffic

There are a few Diverging Diamond intersections around here and they seem to all work rather well from a vehicle perspective. I can't speak about the pedestrian side of that equation, as I've never been on foot.

Compares to a roundabout placed over a highway, it uses 1 bridge instead of two, but otherwise I don't know which flows best.

athenot··on VCs aren’t your friends
It still comes down to risk management.

VCs manage risk differently than bankers, but they still need some form of assurance that their investment will bear fruit. They are not as rigid as bankers but they are still in the same position of having to rely on proxy signals to predict the future.

They can catch more non-conformist value builders† but not every single one.

†For a VC, innovation is a means to building value, not an end to itself. Often the 2 are used interchangeably but only the finances matter in the end.

athenot··on When children become caregivers, who cares for them?
This (along with odds of survival) was traditionally the main reason for having many children. They were help around the farm but also a form of life insurance.
athenot··on Other People’s Problems
Yes! I'm always reminded of "Just is a Dangerous Word", from the original wiki:

https://wiki.c2.com/?JustIsaDangerousWord

athenot··on There’s a 30-year old dead Rabbit in Seven Sisters tube station
In France it was branded Bi-Bop and ran from 1991 to 1997; many public places had the stickers to identify where service was available. Apple even had a Bi-Bop modem to go in the PowerBook laptops. Futuristic at the time but pricing pretty much kept it from getting much traction.

athenot··on Why is it so hard to build an airport?
That's similar to people who move to the countryside then complain that the farms nearby stink.
athenot··on Inside the Massive Alleged AT&T Data Breach
I use unique email addresses for each company; the one I use with AT&T (and only them) is in the dump. So I know at least the email was leaked from them.

Of course that doesn't say anything about the other PII but at this point, I figure my PII has already been leaked multiple times.

athenot··on Humanity Is Dangerously Pushing Its Ability to Tolerate Heat
In Atlanta the tap water in summer is more like 22°C (72°F), which is coincidentally the average nighttime temperature.

I could imagine that a place where the nighttime temperatures are in the mid 30s (°C) would not have any cooler water available.

athenot··on Varda Capsule Reentry – Five Minutes from LEO to Earth [video]
That is still an impressive aim that y'all achieved. Congrats!
athenot··on U.S. opens UnitedHealth antitrust probe
For those not familiar, here is the one on Optum & United Healthcare:

athenot··on Botanical gardens can cool city air by an average of 5°C
From an energy perspective it makes sense, since at least some of the solar energy hitting tree leaves is used for photosynthesis, and reducing Carbon out of its oxydized state. So it's not just accumulated/reflected like for pavement.
athenot··on FCC rules AI-generated voices in robocalls illegal
Now that you mention it, "dry pancakes" would make a great insult. I always love expressions that take the listener a moment to process.

- What did they mean?

- Was it an insult?

- Why "dry"?

(thinks some more)

- This is the lamest insult ever!
