tsycho··on Show HN: Wealthfolio: Private, open-source investment tracker
Does it support options, or only stocks?

How do you get current market prices for investments?

tsycho··on Your Immune System Is Not a Muscle
My friend also developed almost continuous eczema for the past couple of years, and tried cutting out a large variety of foods from her diet to see what might be causing it.

Everything failed. And then, one day her normal brand of shampoo (which she had been using for 5+ years, and is advertised for sensitive skins) ran out, and she didn't get a chance to buy it for a couple of weeks. To her surprise, no eczema during those weeks! She changed her shampoo brand, and her eczema problems are gone, at least for now.

My point is, if you are trying to selectively eliminate things from your diet/lifestyle to figure out the trigger of your eczema, don't ignore things that you have been using for years before your eczema started.

tsycho··on Sending emails to my three-year-old
I thoroughly recommend this.

I have been doing this with my kid since birth as well. I tried building an app first, but decided that the maintenance costs of email (close to zero), and the easy access to multiple people (only my spouse and I for now), made email the simplest solution.

My sending frequency has reduced a lot now, but it used to be 3-5 times a week in the first few years. Once in a while, I'll open the account and read the old emails and they are a beautiful time capsule.

tsycho··on How Waymo outlasted the competition and made robo-taxis a real business
I have the opposite take/hope.

Self driving buses will be such a boon for public transportation. Now you can have 24 hour buses, that operate on holidays as well, or even dynamic, short term routes based on demand (eg: after a concert or sports event), without being dependent on the availability of pre-allocated human drivers.

tsycho··on Ask HN: Video streaming is expensive yet YouTube "seems" to do it for free. How?
This comment is a great answer to those commenters who say "Google bought YouTube/Android/..., they haven't invented anything since Search" miss the actual hard part entirely.

(same for Meta wrt Instagram)

These products that have been scaled by multiple orders of magnitude since original acquisition are like ships of Theseus; almost everything about how they work, how they scale and how they make money, have completely changed.

tsycho··on Google I/O Thoughts?
I thought Gemini 1.5 Pro is available immediately, and the Workspace stuff is coming in 1 month.

Fair point if you are talking about the video understanding stuff, I don't know when that's coming.

tsycho··on Google I/O Thoughts?
All the video understanding and agentic stuff (if it actually works at low-enough latency in real life) is very impressive.

Put this on a robot, call it Jeeves, and it becomes a pretty cool personal assistant :)

tsycho··on Google is an 'amazing example' of employing people in 'BS jobs'
I see articles like this claiming that there are tons of employees at Big Tech who get paid for doing basically nothing.

And yet, my (and all of my friends') combined observed experience of Big Tech is the opposite. Almost every team is understaffed, especially after layoffs.

It's not that there aren't inefficiencies; but they are of a more procedural/bureaucratic kind. Eg: layers of approvals or privacy reviews to do any analysis on user data, or poorly documented internal tech stacks with a high ramp up cost.

Has anyone here who works in Big Tech actually met these hordes of employees who are given no work for months?

Exceptions can happen in any large company (eg: someone joins a team right when a reorg is happening, and it takes a month to figure out where they fit in the new org), but I am extremely skeptical that this happens on a systematic basis.

tsycho··on Book people think they know why 9-year-olds stop reading for fun
I agree, and have the same problem.

What books did you end up liking for 9 year olds?

tsycho··on Ask HN: What is the biggest thing you've changed your mind about?
It's amusing that most of the child commenters assume that you switched from left to right, while you were (intentionally) neutral about that.
tsycho··on Identifying Stable Diffusion XL 1.0 images from VAE artifacts (2023)
Has anyone tried training a neural net to distinguish between photographed vs AI generated images?

Of course, you will need to remove exifs or other metadata, but this sounds like the kind of domain that NNs are good at.

tsycho··on Low Cost Robot Arm
Here's what I want to build:

A rotatable, table-top round disc base, with a contraption to keep a mobile phone straight and stable. The stand itself will have 4 small unidirectional mics, to figure out which direction (after filtering for human frequencies, ideally) is the sound coming in. And based on that, it will rotate the phone to face that direction (continuosly).

The use case is family video calls that I do frequently from my dining table (my whole family is sitting around the table, hence there is no one good spot to keep the phone). With this self-rotating stand, the phone will auto-rotate towards whoever is speaking.

I can write audio-processing code, but I have no idea how to get started with the hardware. Feel free to steal my idea, but please share with me how you are building it. I just want this to exist, and I want to know how to build it for myself as a fun project.

tsycho··on Microsoft again bothers Chrome users with Bing popup ads in Windows
Which OS are you taking about?

In this article's context (Windows), you would have put in the effort to download Chrome yourself and then used it, which is a heck of a lot of intent, as compared to what Microsoft is doing here.

tsycho··on New Federal Rule Caps Credit Card Late Fees at $8
This still happens consistently, and I don't even have to leave the country, I just have to buy flights to a foreign country (eg: for vacation) or buy something from a foreign website (eg: buying a gift for my family).

The only reason I use them is for their 2% cash back on everything, but I have stopped using them for any non-domestic purchases.

tsycho··on Apple hit with over 1.8B euro EU antitrust fine in Spotify case
I see comments like yours, and I seriously can't tell if you're trolling or whether you genuinely believe this. However, I'll try to answer (once) in good faith.

There are so many things in life, due to either scarcity, lack of options, laws, or prior investments that we have made, that we can't leave them easily, even when we dislike a subset of our choice.

If you hate Comcast's service, but they are the only available broadband option in your city, would you leave your city just for better internet?

If you don't like 10% of the policies of your current government, but dislike 50% of the policies of the opposition, would you start your own political party?

I like a lot of things about iOS as a user, including the quality of their hardware, but I dislike the dictatorial control that Apple exerts over both developers and consumers. Not just their anti-steering provisions (which is pure rent seeking), and lack of sideloading (which I want), there's no way for me to write my own app and install it on my own device, and have it run permanently without paying Apple even more money.

I bought the phone at full price, I hate Apple's attitude that I have just bought the privilege of using it as per however they see fit. And so, similar to above, my alternative is to switch to something like f-droid, and lose my hardware, lose my purchases, and in many cases, lose my ability to even use my phone for standard communication (eg: iMessage). Or maybe you would suggest that I build my own phone company

In all these cases, the alternative option is possible, yes, but it's very impractical and infeasible for the vast majority of people to pursue, and they come with serious negative costs. So we pursue them only when things become unbearably bad, as a last resort.

And so the feasible option is to complain, protest, and try to leverage the government/courts to change the rules so that large companies can't take advantage of us and keep exploiting us in a "boil the frog" manner. And if that doesn't work, then one day, my cup of frustration will overflow, and I will switch over to f-droid or something

tsycho··on Automated Unit Test Improvement Using Large Language Models at Meta
1. Define your APIs in terms of "what" it should do, not "how" (which is for the implementation).

2. Use protocols/interfaces in Swift/Java to define APIs.

3. Then write tests to the API's public contract, without using internal implementation details.

Tests written in the above way will actually detect bugs, and stay stable to internal implementation changes that don't affect the external behavior.

tsycho··on The Backpage Defendants Never Stood a Chance
But why would legalization of prostitution increase sex trafficking, which is already a crime? With legalization, sex workers have more rights and a higher ability to go independent, or to go to the police when they suffer abuse.

I suspect that the amount of sex trafficking is actually determined by the amount of nearby vulnerable men/women with low economic prospects. It's a red herring to look at any correlation with legalization and consider that as causation.

tsycho··on Gmail and Yahoo’s 2024 inbox protections and what they mean for email programs
Their algorithms very likely look at (I hope so, at least) spam marking rates. I would bet that users mark promotional emails at a order of magnitude higher rate than transactional emails.
tsycho··on Yesterday, someone sent over $1M in Bitcoin to Satoshi Nakamoto

tsycho··on Figma and Adobe abandon proposed merger
[Pure speculation; I don't work in the UI space at all, and at neither of these companies]

I wonder if Adobe is secretly happy about this. They were acquiring Figma at the peak of the market (for growth stock/startup valuations) because of the existential risks that Figma was threatening, due to their collaborative development UX.

But since then:

* Startup valuations have fallen. Ignoring regulatory concerns, a new acquisition deal today would be cheaper.

* Gen AI and Adobe Firefly are the new rage, and Adobe has probably captured back both mental and market share from Figma. And Adobe can now add collaborative features to Firefly, and it doesn't even have to be as good as Figma's to win.

So paying the 1B breakup fee is probably the cheapest and best option for Adobe at this time.

Meanwhile, Figma employees, expecting a big payout, are probably a bit demotivated at this point. And potentially, they might have been working on integrating into Adobe over the past year, so they might have even slowed down in their development pace.

tsycho··on After a $1.8B verdict, the clock is ticking on the 6% realtor commission
Now imagine a world where realtor fees are 1% instead of 6%. On a 300k house, that's 15k you don't pay to the realtor. In this world, your realtor doesn't bring you an extra 12k from the buyer, but you still come ahead. And the buyer pays less too.

That's a win win world for everyone (except the realtor, who are redundant middlemen in the internet eta).

tsycho··on Microsoft now thirstily injects a poll when you download Google Chrome
It's unfortunate how any discussion around Google/Apple/Meta in particular just devolves to the same repeated talking points :(

For the "Google does it too on google.com" commenters, imagine if Microsoft did this when you are downloading Firefox. Would you still find that okay?

tsycho··on Meta starts process to end news access in Canada over law on paying publishers
Spanish newspapers tried this. They failed miserably.

Don't let your dislike for social media blind you from the reality that the world has changed, for the majority of the people in the world. People will spend their free time on these sites/apps, whether or not they have news.

The old local news model is dead. Niche sites like the WSJ, FT, NYT can survive with paid subscriptions, the rest have to find a different business model. This is not a conspiracy by Big Tech or billionaires, as much as we might want to find someone to blame. It's a structural change in the ether of society, information and distribution. Anything with near zero marginal costs of distribution needs is now in competition with the whole world, and unless they have something unique that people are willing to pay for, their days are numbered.

tsycho··on How Doctors buy their way out of trouble
WTF! How are these doctors not in jail? The medical system in the US is even worse than I thought
tsycho··on First Republic, other regional bank stocks sink after failure of SVB
As an individual, you have much lesser money to spread around than a company. If a company with 25+ million in cash has to manage more than 100 accounts, they are more likely to make some other banking mistake and lose some of that money through some administrative mistake.

That said, I sympathize with your broader point. With hindsight, it would make more sense for a company to have a brokerage account, and do something like invest their cash 1/3 each in 1-month/2-month/3-months Treasuries, rolling over every month.[1]

But most tech CEOs/founders of tiny startups probably don't know much about finance, and I can't really blame them for just putting their cash in a large bank.

[1] There's a startup opportunity to build this product right now, a pure custodian-style cash-management "bank" for small companies.

tsycho··on FDIC auction for SVB said to be underway, final bids due Sunday
Interesting thought, treating your debt like a bond.

If you no longer need the debt, i.e. you have the cash to pay it back, you could _theoretically_ loan out that cash to someone else at the higher current market interest rate. Loaning money involves credit risk of course, so practically this would mean buying something like higher interest paying Treasuries or AAA bonds. Effectively, the spread between your borrowed fixed rate debt and the bonds you bought are the _profit_ you make, the NetPresentValue of which is roughly what you would get if you could "buy back" the debt.

tsycho··on Amazon’s big dreams for Alexa fall short
With Apple, people consider even their failures as features :s
tsycho··on Show HN: Self-host Whisper As a Service with GUI and queueing
Is there an open source speech recognition model which can be restricted to a smaller domain-specific dictionary?

Use case: I want to transcribe my poker hands while playing, eg: "Flop was 2 of spaces, 3 of diamonds and King of spades", "Button raised to $20" etc.

When I tried using Whisper and some other model, the recognition accuracy was atrocious, and it kept finding non-poker words that sounded similar to poker words. I want to restrict its search space to my own list of poker words which should significantly increase the accuracy (theoretically).

Any suggestions on how to go about this?

tsycho··on Omg.lol – A lovable web page and email address
And offers a generous notice period, and data transition options, when it shut downs.

To be fair, this should be what to expect from any large corporation, but sadly, many don't.

tsycho··on Ask HN: Do you recall any book or course that made a topic finally click?
While your question itself is good, it's unfortunately quite likely that the recruiters won't actually know the answer. So their answer isn't a good signal.

Separately, in larger companies, there will be significant variance between the onboarding process of teams/orgs.
