sparker72678··on For Linux kernel vulnerabilities, there is no heads-up to distributions
Sure, maybe it's not a _requirement_, but now we're all in more pain because the reporters are more interested in Fame than Safe Remediation.
sparker72678··on Good Taste the Only Real Moat Left
At least in part because some of Taste is fashion.

Wait til you find out about Wifi and GSM!

sparker72678··on What's in that bright red fire retardant? No one will say, so we had it tested
We should know what’s in the retardant, yes.

The alternative to retardant at the moment is uncontrolled wildfires.

sparker72678··on Why are credit card rates so high?
But once the scam has permeated the system, it's to your advantage to participate, because you pay either way.

sparker72678··on Literate programming: Knuth is doing it wrong (2014)
Seems like many devs don't even like to code. They just want to get paid.

(Not suggesting there's something wrong with that, per se. But good luck getting someone's who just in it for the money to go above and beyond.)

sparker72678··on California bans legacy admissions at private universities
I can't see any way this holds up in court. What am I missing?
sparker72678··on In a first, Phoenix hits 100 straight days of 100-degree heat
Developers don't care about cost of operation, only cost to build. If there weren't efficiency rules in building codes developers would still be building houses with paper walls here for $750K.
sparker72678··on In a first, Phoenix hits 100 straight days of 100-degree heat
Swamp coolers are not effective during at least July-September, when the dewpoint regularly rises to 65°F+ for weeks at a time.

Drier than the south still isn't dry enough when it's 117°F with a dewpoint of 65°F. You'll end up with output temps in the high 80s (or higher), and the output air will be extremely wet.

sparker72678··on Scaling Rails and Postgres to millions of users at Microsoft
Were they running t2.micro instances or something?

We're running 270k+ RPM no sweat, and our spend for those containers is maybe 1/100th what you're quoting there.

The idea that Rails can't handle high load is just such bloody nonsense.

You can build an abomination with any framework, if you try.

sparker72678··on New anti-speeding system coming to Australia is dangerous
Once it goes beyond alerting, this is going to kill someone.

A driver will be on a 2-lane road (1 lane each way), and attempt to pass the driver in front of them. A car will be coming the other way, and they won't be able to get in front in time.

They'll try to slow and get back in, but the other cars will have filled the space. They'll have nowhere to go.

Perhaps in this example the driver shouldn't have tried to pass in the first place, but removing an "out" from this situation, in which everyone gets to go home to their families, is a horrible idea.

sparker72678··on RubyGateway: Embed Ruby in Swift
This is probably not what anyone who reads this title is expecting it to be.

On the other hand, there's a project on iOS, "Rubyist", that embeds mRuby and lets you actually write, parse, and execute ruby code within your app. It even has some hooks for calling into some iOS APIs (Widget APIs, most notably). It's a fun idea, but might be a dead project. https://rubyist.app

I wish there was a canonical Xcode project getting mRuby imported into an iOS/Mac app, so anyone could use it as a starting point for their ideas. I dunno, maybe one is out there and I just haven't found it?

sparker72678··on I'm Back, Ruby on Rails
Curious: what version of Rails was the codebase was running, and how long it had been around before it landed in your lap(s)?
sparker72678··on Houston-area residents enter sixth day without power, air conditioning
Profit does not rise proportionally with costs as reliability increases (i.e. it costs a lot of money to make it more reliable, but you don't get to charge substantially more). The electric company monopoly does not have incentives to spend money to be more reliable. All the downsides of widespread power outage are externalized onto the customers.
sparker72678··on The American West is figuring out how to keep cool
Have you ever been to the American West? It's nearly all suburban. You would literally have to raze what's there and start over if you wanted to be able to efficiently transport people with public transport.
sparker72678··on Ask HN: Why are ads the major stream of revenue in any kind of digital media?
tl;dr Ad-driven revenue models let you distribute your content to the widest possible audience while still making money.

The marginal cost of digital distribution is (basically) zero. As a result, you have an incentive to chase the widest possible audience. This is going to drive your pricing downward to reach as wide a market as possible. The math is like this: A 1000x audience size is worth it even if you lower prices 99%.

At the same time, advertisers would like to reach as large an audience as possible as well. And, in many cases, you can charge _more_ for selling ads to a larger audience. (Either the ad goes to a huge number of people, as in traditional brand advertising, or you have more niches to target.)

So you simultaneously have incentives to drive your own prices to zero, because it drives up your audience size, and that simultaneously increases the prices you can charge for ads.

From an on-paper business perspective, it's simply the best model. It's why TV, Newspapers, and Magazines all did this before the Internet, and it's why the incentives are bent even more towards ads in a zero-marginal-cost-distribution environment today.

Yes, in the real world there are tradeoffs to all of this, but these are the major incentives at play.

sparker72678··on The iOS bug that made deleted photos reappear
> Based on this code, we can say that the photos that reappeared were still lying around on the filesystems and that they were just found by the migration routine added in iOS 17.5. The reason why those files were there in the first place is unknown.
sparker72678··on Congress Just Made It Basically Impossible to Track Taylor Swift's Private Jet
Unless they have a way to roll the ADS-B info, it should be pretty easy to work all this out.

Hard to imagine this will actually make jet tracking sites/accounts/etc disappear.

sparker72678··on Discussion: Job seekers can't find a job and Employers can't find an employees
The best way to get a job _has always been, and will always be_, knowing somebody.

Networking is an essential life-skill, and worth all the discomfort it takes to get better at it. (You don't have to be the top 1% of networkers to be successful).

This. YouTube video sponsorships, too.
sparker72678··on The Oregon Outback International Dark Sky Sanctuary
The progress Dark Sky International (and friends) has made is very encouraging.

I have been extremely pessimistic about the dark sky movement making progress at all given how desperately fearful of any darkness the areas around me seem to be (daylight-bright streetlights, storefront signs to rival Vegas, etc.)

Truly dark skies are magical. I'm so glad they'll be around at least a bit longer.

sparker72678··on From Seattle move in a straight line due East. What country will you hit?
Title here, "From Seattle move in a straight line due East. What country will you hit?" is subtly different from what the article is describing: "From Seattle, face due East. Now, continue forward in a straight line..."
