underyx··on Exchange Fund Investor Defers $388K Taxes, Comes Out $278K Ahead Amid Volatility
From what I can tell the effective value of the "Cache Exchange Fund (After fees and expenses)" portfolio will be $660,282 once liquidating to actually use the money? Is the point that this allows waiting for a possible lower tax rate in the future? Or is the point that if the holder was really strapped for cash in this exact moment, they would have to pay less taxes now?
underyx··on DOGE worker’s code supports NLRB whistleblower
Also this PDF contains a detail I haven't seen reported elsewhere:

> Furthermore, on Monday, April 7, 2025, while my client and my team were preparing this disclosure, someone physically taped a threatening note to Mr. Berulis’ home door with photographs – taken via a drone – of him walking in his neighborhood. The threatening note made clear reference to this very disclosure he was preparing for you

underyx··on What really happens inside a dating app
This is such a detailed article but it's giving me weird vibes.

For instance there are all these drops to near-zero in the histograms at .28, .46, .56 for no clear reason, and the article doesn't even consider that noteworthy.

The "Men Like ratio (y) vs ratio (x)" has an inexplicable wall around .33 which I could only explain with some sort of product limitation maybe? But I really wish it was explained what artifacts the product introduces.

I also got it around 40 minutes later!

My phone is on English (US) and I live in San Francisco.
underyx··on Apple Intelligence is available today on iPhone, iPad, and Mac
I updated my macOS and iOS device as soon as I could because I was curious to finally see how these features will work.

Turns out it's not even available today! The Apple Intelligence settings just showed a "Join waitlist" button, I clicked it and it says "You'll be notified when Apple Intelligence is available for [you]".

underyx··on BBC Weather app bug suggests hurricane winds in UK
This bug was added for those who open BBC Weather in a rush to hide the actual page they were looking at before. The hurricane news make it look more plausible that you were looking at something interesting on the weather page.
underyx··on Oura Ring 4
I had the exact opposite experience with support, possibly the best one yet with any company.

I opened the live chat on the battery life support page and the chatbot asked (paraphrased) "Is your battery bad? Put in your email address". I put my email in and the next automated message was "Seems like your battery is underperforming, where should we send a replacement ring?"

I got my replacement a few days later.

underyx··on 300μs typo detection for 1.3M words
Sure, but why does the title claim 300μs typo correction?
underyx··on 300μs typo detection for 1.3M words
Title:

> 300μs typo correction for 1.3M words

Article:

> 300μs for correctly spelled queries and ~5ms/word for misspellings

Aren't these contradictory?

underyx··on Making PyPy's GC and JIT produce a sound [video]
There's a blog post from 6-8 years ago I can no longer find anywhere, where someone made node.js create similar ambient sounds and compared it to listening to hard drives doing mechanical work to understand what the computer was doing. Apparently it was actually useful to audibly hear when, for example, a request failed due to an authentication problem which had its distinct sound emerging from the pattern of code execution on that branch.

Does anyone have a link to what I'm talking about?

underyx··on Fine-tuning now available for GPT-4o
Gotcha, thanks for the answer! We're a pretty heavy user of OpenAI (my company's called Semgrep) and I'd love to know if you ever run private betas or work with development partners for features like project permissioning. If so, feel free to email me at bence@semgrep.com — otherwise, appreciate your work on improving this!

This:
underyx··on Fine-tuning now available for GPT-4o
I mean OpenAI hosted fine-tunes (same as referenced in OP.)

I have a staging deployment and a production deployment. Ideally anything that I roll out to production, I can try on staging first — including switching from gpt-4o to a fine-tuned gpt-4o. I don't want the production API key to be accessible by my staging app, so I have two separate projects within the OpenAI dashboard. One is called my-app-prod, and the other is my-app-staging.

To illustrate the problem further, I also have infrastructure to eval models before changing what production is running. The eval infrastructure also has its own OpenAI project, so that I can set separate billing limits on running evals. Any fine-tuned model needs to be benchmarked first, but again, I'm not sure how to make the same fine-tune available to both the eval project, and the production app project.

underyx··on Fine-tuning now available for GPT-4o
How do y'all deploy fine-tuned models? I have separate projects for staging and prod, but it doesn't seem like a fine-tune can be shared across projects.

Am I wrong to split projects by env? Am I expected to run fine-tunes separately per env (surely not)? Am I missing an option to share fine-tunes across projects?

underyx··on Self-driving Waymos secure final clearance for expansion beyond S.F
Their policy from an email sent out Oct 2023:

> Many of our riders choose Waymo for the clean and consistent vehicle we offer. To ensure every rider gets this experience, we’ll be applying a vehicle cleaning fee for riders who leave a mess behind in the vehicle, such as vomit, excessive trash, and smoking odors.

> For those that self-report their mess during their ride (not including smoking), the fee will be $50. For issues that go unreported, we’ll charge riders $100 for the first violation and increase the fee for subsequent violations. Repeat trash and smoking related violations may also impact your account standing.

underyx··on Bouba/kiki effect
I think in the US kids use buses (school buses) at a higher rate than adults. The bus in the image is also colored yellow, just like school buses. Perhaps it has more to do with kids just having more recent experiences solving the same problem in real life?
