anonu··on A brief history of the Bloomberg terminal
that's a perverse way of looking at the cost of a service offering.

it's saas with authenticated market data.. there's nothing to crack

anonu··on iPhone Duo
As a recent Android foldable phone owner (Google Pixel), I'm excited that the Duo will get developers to actually design apps for foldables. Right now, some apps don't work at all and others are just stretched. I feel a better use of the screen space is around the corner for both Android foldable and Duo users.
anonu··on 216M Spy TVs – The LG Smart TV Problem [video]
Can this be blocked with DNS / firewalls? Anyone done any work on that?

Is there a DNS setting in LG? Could it be as simple as switching to a local DNS server on your network running nextdns.io?

Lets hope that those touting a "reversion to the mean" are right.

anyone know exactly how this works?
anonu··on AI financial advice is surprisingly good if you ask the right questions
You need to feed it high quality data. Try Gemini Notebook, but this time load up a spreadsheet of fundamentals information for all US stocks or ETFs. The answer will differ and be much more nuanced.

I dont think you can rely on an out of book chat agent today to have all the necessary information at its disposal - even if you can pull a stock quote in ChatGPT, it doesn't mean it's going to look at PE multiples on 5000 stocks...

anonu··on How to Spot AI Writing
> With every update, our study shows, AI writing is becoming more similar to human prose.

Any possible vice-versa: There's a meta problem with AI writing detection. I have found my (non-AI-assisted) prose possibly enhanced or modified by my learnings and observations at how LLMs write. In some sense they have made me better at structuring my thoughts and how to communicate them.

anonu··on Show HN: I replaced a $120k bowling center system with $1,600 in ESP32s
Thank you for sharing. This type of stuff gets me pumped up. It just shows that tech improvements usually 10x - or in this case 1000x - some old metric. In this case its cost. I think the same sort of rule of thumb applies to things like speed, features, user experience, etc... Getting this type of cost advantage eventually translates to a better UX, as you've alluded to. Way to go.
anonu··on Is this the end of the once-mighty GoPro?
> Apple somehow reigns supreme still.

Apple reigns supreme because of China - and the two are inextricably linked. China would not have its high-tech manufacturing prowess if it were not for Apple. The book Apple In China [1] highlights how millions of cheap laborers and the country's engineers took the lessons of working with Apple to solidify its edge in this space in a way nobody can catch up to today.

China took the long-term greedy approach to invest in the relationship. We see the US today taking equity stakes in Intel and trying to play catchup by using elements of the same playbook. The US's advantage remains in the more "intangible" side of the process: creativity, design, new tech. In a global economy with free trade, this is all fine. But China never "westernized" itself as was expected from the increase in global trade. Now the US is back pedaling, trying to jump start its manufacturing. It will take a long time...

The book is a good page-turning read. I recommend it.

anonu··on Thanks HN for 15 years of support and helping me find my life's work
First off, congrats. This sounds incredibly fulfilling on many levels.

Second, I'm curious how your business changes with AI coding tools. I would wager humans will seek out your offering in greater numbers.

anonu··on Funny item co-occurrences in 3.2M Instacart orders
Berries are most certainly not seasonal anymore. They should be but we thoroughly engineered the seasonality out of them. They're always on the shelf. Do people's purchase habits follow the natural seasonality of the product anymore? Probably something that can be found in this dataset as well.

anonu··on Claude Code sends 33k tokens before reading the prompt; OpenCode sends 7k
This is all heading in the right direction. Much of AI coding feels magical. But when the costs begin to accrue we start asking questions. We dig into it and try to understand what's going on. I can't help but feel Anthropic is "token maxing" from its side: it controls the levers and with every version upgrade it can build in its own token growth almost unbeknownst to the user. This actually harms it on the long run because it necessitates a cheaper option.
anonu··on I think I have LLM burnout
It's burnt me out too. I'm generating 10x more features and multitasking across 4 disparate projects. My greatest concern is I don't really have a strong connection to the underlying fundamentals anymore. I need to see how the things works to internalize it. Now I just trust that the agent wrote this piece correctly.

The productivity drive and the sheer feature set you can generate in record time makes it easy to forget proper sdlc hygiene.

anonu··on Half-Baked Product
> When Everything Is Urgent, Nothing Is

The most resonant line for me. This line for me is about how good project management meets team culture. You want a high performant team: one that remains focused and motivated - but the goals are carrots, not sticks.

anonu··on Marfa Public Radio Puts You to Sleep
Love this. I'll try it.

Ive found great success with the Military Sleep Method where you progressively shutdown your body from head to toe.

anonu··on AI learns the “dark art” of RFIC design
One takeaway from the article is that they had to get rid of the tried and tested fundamental building blocks of chip design to generate this advancement. I wonder if the same applies for mundane coding. Are the incredible innovations in AI coding actually hampered by rust and python? Should we let AI tools just code in the lowest level possible?

Cool. There's a few sites now. I've been using signalbloom.ai and it has 5000 US ETFs.

glad to see that Stack Overflow (or stackexchange.com) is still a thing.
anonu··on Ask HN: What was your "oh shit" moment with GenAI?
Gave Claude a third party vendors binary market data stream. With no spec and 20 minutes of hex dumping it built a parser and a cool TUI. Wow...

That kind of work would have taken weeks if done by hand. Even after obtaining message specs and more

anonu··on Pentagon raised threat of Israeli spying on U.S. to highest level, sources say
The well publicized disagreements are just diplomatic cover. The USA can look tough. Israel might back off for a little bit. Everyone looks good for a moment. Reason has prevailed. Then it'll all go back to Israel's criminal "gaza policy" in South Lebanon, continuing the wanton murder of 1000s of civilians under the guise of "they use children as shields". Well yeah, it's endless guerilla warfare and now hezb has drones. Diplomacy is the only way.
anonu··on S&P 500 rejects SpaceX, also blocking entry for OpenAI and Anthropic
You'll eventually get exposure to it when it gets added in 12 months. Unless there are better profitability criteria. Ultimately it's all about market returns. If other indexes add it and outperform then eventually money will shift to those funds that do better.
anonu··on A Probabilistic Algorithm for Repairing All Roads in Lebanon via Papal Visits (2025)
For anyone curious: the most destructive force is the Lebanese themselves, at least in the last 30 years. Israel has only recently taken first place.
