k2enemy··on Apple testing new App Store design that blurs the line between ads and results
Thanks, I gave it a try. I see the download, but it isn't signed for newer iphones. Only ones that don't support iOS 26. So frustrating. I'm on a 12 mini and people report that 26 runs horribly on it.
k2enemy··on Apple testing new App Store design that blurs the line between ads and results
I could not agree more.

It probably doesn't help that I just spend an hour trying to figure out how to update to 18.7.3 on my iphone. It turns out you can't. The only way to get security updates now is to upgrade to iOS 26. Apple no longer supports security updates to old major versions if the device is capable of running the new major release. Apple is no longer making choices that benefit customers, but ones that benefit project managers.

Kind of ironic that there's a big overlap in the venn diagram between 2nd amendment enthusiasts and the crowd that is cheering on the government's authoritarian actions.

These are also easy to DIY with a raspberry pi, rfid card reader, some blank cards, and phoniebox [0] for the software. I don't have much electronics experience and had it up and running fairly easily for under $40.

k2enemy··on Microsoft May Have Created the Slowest Windows in 25 Years with Windows 11
MacOS seems to be going the way of Windows, with unnecessary and distracting notifications for things users don't care about. Then on top of that, the whole liquid glass redesign that hurts usability and information density.

Definitely moving in the direction of "what is good for a particular PM" and not "what is good for the user." I would have switched to linux years ago if it were not for the great hardware and I like having access to iMessages from the desktop.

k2enemy··on Feynman's Hughes Lectures: 950 pages of notes
Almost a thousand pages of presumably well thought out and neatly written notes. For lectures, and not even his own research. I'm always amazed at the productivity and output of the great ones.

And to think, people are concerned that humans will struggle to find meaning in life after the AI utopia obviates the need for work.

This editorial elaborates on some of the political corruption, as well as Iran's dismantling of cooperation with foreign water engineers.

k2enemy··on The Rapper 50 Cent, Adjusted for Inflation
That's an incredibly misleading graph. Never look at something with a growth rate on a linear scale, as it will always have a "hockey stick" shape, even with constant growth. If you look at the same series on a log scale, you see high inflation in the 70s, but from the '80s on it looks pretty similar to the pre-70s trend.
k2enemy··on What Americans die from vs. what the news reports on
Probability of punishment seems to matter more than severity of punishment. This follows from economic and game theoretic models and is backed up by empirical studies.

k2enemy··on California passes law to ban ultra-processed foods from school lunches
>> In July 2025, the federal Centers for Disease Control (CDC) reported that 32.7 percent of children and youth between 12 and 19 years old are prediabetic.

> Wow.

Sadly, I'm not too surprised. My state also has free breakfast and lunch in public schools and it is possible for them to get served over 100g of added sugar between the two meals and classroom provided snacks. Then add to it whatever the kids are eating at home.

It also creates added difficulty for kids to concentrate on lessons when their blood sugar is spiking and crashing repeatedly throughout the day.

k2enemy··on Show HN: Re-Implementing the macOS Spatial Finder
Cool! Are you using an emulator for that or an old mac? I'd be interested in hearing more if you've written it up somewhere.
k2enemy··on The collapse of the econ PhD job market
> Mostly using Convex Set Theory and Brouwer Fixed Point Theorem from topology to prove the existence, uniqueness, and stability of a general equilibrium solution for a "market" of price-quantity commodity pairs. The assumptions needed to make it work are literally absurd.

This is true for the first foundational courses in micro and macro. The profession has moved beyond this and the last forty plus years of research have been looking at various relaxations of these assumptions.

k2enemy··on I spent the day teaching seniors how to use an iPhone
And after all of that there are still red bubbles nagging you to sign up for various services and to enable features you already said no to.

I remember switching to Mac years ago to avoid this type of user-hostile crap in Windows.

MLB.tv with a vpn. Works for the postseason too :)
k2enemy··on Playball – Watch MLB games from a terminal
It seems like MLB themselves have been experimenting with this. On their website, they have a feature called "gameday" that animates the game. For a while now they've had a 2d view, but now they also have a 3d view that you can switch to.

It is buggy as hell, but neat that you can move around the field and watch player movement off the ball. But there are a ton of glitches, like players getting frozen or duplicated, batters, umps, and catchers getting swapped (funny to see the ump at bat), and mixups with mount visits. In time, I can imagine this as a great way to watch though. Especially for novice players and fans learning the game and trying to figure out things like who should back up which throws in which situations etc.

k2enemy··on Kagi News
I like 1440 (https://join1440.com) for this. Once a day daily email digest. I like the email format because I'm less likely to start clicking around compared to a web site, and it doesn't require a separate app.

I think it is human curated, but I'm not positive about that.

k2enemy··on Cosmic simulations that once needed supercomputers now run on a laptop
Great to see a Julia project featured. I keep rooting for Julia to take off, but python's dominance in AI has me doubtful.

It is such a great language, and capable of ML and AI workloads, as evidenced by this research.

k2enemy··on Will I run Boston 2026?
Making sure they can accept a lot of high disposable income 40+ runners that will buy a lot of merch. The time cutoffs start to get much easier after 40.
k2enemy··on US High school students' scores fall in reading and math
Maybe. I've definitely seen that anecdotally in some cases. But the school system is also problematic for the families that do value education and the kids that could excel in the classroom.

Our district has eliminated programs for the kids at the top end in the name of equity. They've also eliminated separate spaces for kids with learning and behavioral issues for the same reason. So everyone is in the same classroom and most of the teacher's time is spent on a handful of kids causing trouble and the rest of the class learns nothing.

We can't afford private school, so we're doing a bunch of extra lessons at home to keep them on pace, engaged, and challenged. But really, there are only so many hours in the day and I want them to be outside playing too!

k2enemy··on U.S. added 911k fewer jobs in year through March than reported earlier
If we are heading into a period of high inflation and interest rates, holding debt now is great. High unexpected inflation means that the dollars that you use to pay off the debt are worth less, and you are locked in to a low interest rate.

Boy do I feel old if a short, low content PSA about the existence of RSS is considered "hacker news."
k2enemy··on The Folk Economics of Housing
> Is it that they truly don’t believe it or they don’t want more supply

If this comment section is anything to go by, there seem to be plenty of people that firmly believe that increasing housing supply doesn't actually increase housing supply, let alone the bigger leap that increasing housing supply decreases prices.

k2enemy··on Simulating and Visualising the Central Limit Theorem
It is correct in the article. As the sample size approaches infinity, the distribution of the sample means approaches normal.

I guess "random and pleasing" is appropriate for both CM-5s and LLMs.
k2enemy··on Show HN: Sharpe Ratio Calculation Tool
I was wondering too. If someone is sophisticated enough to have their return data in a CSV, calculating a Sharpe ratio is trivial. The hard part is already done.

> Our tool automatically uses the up to date Secured Overnight Financing Rate (SOFR).

Are risk free rates matched to return dates? This makes it sound like the tool uses a single risk free rate for all excess return calculations.
