UX is hard. What usually happens is that you have:

- developers who are bad at UX writing the software and improvising with all the use cases that were not adequately specified in the design document

- end users who are bad at UX giving their input, but can tell when something feels right for their use case

- managers/spec writers who are bad at UX and are trying to translate the wishes of end users to the developers

The result is a worthless spec, garbage in, garbage out.

Sometimes, when the stars align, in your team you get someone who is actually good at UX. I am told this happens, because in my career I have never seen such a unicorn. And even in that case, the end user with no understanding of UX, the one that actually pays for the project, might really, really want that periwinkle blue button, so in pretty much all cases GUIs get through countless rewrites and tweaks.

I have been interested in algorithmic trading for quite a while now. Everything you've said resonates with me as I ran into similar issues. I hope you don't mind that I add my own couple cents here.

(a-c) LLMs are especially difficult to use due to their knowledge cutoffs and "unpredictability". A self-trained "old-school" machine learning model can go a long way though.

(d) With Crypto the volatility is great for trading, but liquidity can quickly become a problem (even at $1000 non-leveraged positions). For me, the ultimate goal is to find a strategy that is profitable in all market conditions. I personally value consistency and reliability more than absolute profit.

(e) There's some chatting about risk management, but absolutely no discussion on profitable strategies. Resources are incredibly scarce - Systematic Trading by Robert Caver is the only book that was actually useful.

It will be a major oops moment when we will find out that dementia is caused by some weird kind of bacterial or prion infection. And the whole moral explanation of it ("go read your damn books and talk to smart people or you will get Alzheimers!") will turn out to be same bullshit as moralistic obesity explanations ("just lazy and can't control yourself!") recently turned out to be.

One big thing that changed in these decades is cleanliness simply due to better cleaning chemicals. Which certainly caused a reduction of infections of all kinds.

You don't hear the complaints. That's different than no complaints. Trust me, they got them.

I got plenty of complaints for Apple, Google, Netflix, and everyone else. Shit that can be fixed with just a fucking regex. Here's an example: my gf is duplicated in my Apple contacts. It can't find the duplicate, despite same name, nickname, phone number, email, and birthday. Which there's three entries on my calendar for her birthday. Guess what happened when I manually merged? She now has 4(!!!!!) entries!! How the fuck does that increase!

Trust me, they complain, you just don't listen

You're massively burying the lede here with your statement of 'just take the PRs where the code is straightforwardly reviewable'. It's honestly such an odious statement that it makes me doubt your expertise in reviewing code and PRs.

A lot of code can not and will not be straightforwardly reviewable because it all depends on context. Using an LLM adds an additional layer of abstraction between you and the context, because now you have to untangle whether or not it accomplished the context you gave it.

I'm working with python and it does not work very well, LLMs usually generates at least an order of magnitude more code than what I would write. That code often uses outdated practices, does poor design choices and does not understand hints like writing code in a way that reduce cognitive load, even when we explain that it means, i.e. keep the number of classes and functions small.

It's the complete opposite of OP's main language GO, as he says:

> Go has just enough type safety, an extensive standard library, and a culture that prizes (often repetitive) idiom. LLMs kick ass generating it.

Python is an interpreted dynamically typed language and the static type checkers are not there yet (most popular 3rd parties libraries have no type hints for example). Also it allows for many different programming styles that the LLMs struggle to choose from.

1. Every extra line of code is much more risky. 2. It's much harder to verify the LLM's code.

On the other hand I think rust will be in a good place in regards to LLMs in the next few years thanks to the robustness of the language and the quality of its diagnostic messages. Those 2 attributes should compound very well.
Ask HN: What's Your Spirituality?
by keepamovin | 2025-06-03 09:41:52+00:00
We often consider engineers or tech to be somewhat secular, and maybe some even wear atheism as a badge of intelligence, as in "only weak minds need the consolation of faith" or some such. But I know there's other spiritual, religious people out there, and this question is meant to let you share what you think.

Because I think it's one of the profoundly interesting questions. Intellectually or not.

Another way to engage if that doesn't resonate it: what's a book (or books) you read that profoundly changed your worldview/view of life and when did you read it?
by sylens | 2025-06-03 09:42:08+00:00
The biggest issue to me is one of security. You have to find a way to expose your NAS to access outside the home to make it truly as convenient as the big tech cloud services. Some vendors help do this for you (Synology with QuickConnect); otherwise you're probably thinking about always using something like Tailscale or setting up a reverse proxy on a VPS that you would have to secure, patch, and monitor.

Is being closed on Sunday what leads to round the clock lines at their drive-thru?

Chick-fil-A is very trendy and popular, and they don’t have enough restaurants to meet demand. The customers seem to be driving this, not being closed on Sunday.

If there were 2 equal restaurants, say 2 different McDonalds in similar markets, and one was open 6 days and another 7 days, would we see the Chick-fil-A effect? I’m betting not.

If this was the case, the Filet-O-Fish wouldn’t exist. It was developed by a McDonald’s owner in Ohio where the town was 85% Catholic, and didn’t eat red meat on Friday. He effectively only had a real business 6 days per week and was struggling. The fish sandwich was his answer and turned things around for him.

>You aren't going to 'learn robotics' in a meaningful manner by checking the boxes in a online ROS2 course.

This is the best answer-- all other answers are saying "Run this simulation of a robot".

but a simulation is not a robot. Even a simple lego tupe robot kit shows you how fiddly and complex real world moving parts make everything.

One additional fact to keep in mind - the ability to smell hydrogen cyanide has a genetic component and 1 in 4 people will not be able to smell the "bitter almond" odour [1].

I do wonder how similar the smell of sweet and bitter almonds are, they are apparently different [2].

The "top 10%" thing doesn't make sense mathematically. That depends on the average performance of your classmates. If you were in a school with brilliant students, in a small class, you could be in the top 50%. But with the same performance, just attending a different (low performing) school could put you in the top 5%.

So, keeping performance constant, attending a lower-performing school gives you a higher chance of being accepted at canonical. How crazy is that?

In your link they have only done tests on rabbits.

In this post they have already done some tests on humans and are now increasing the dosage since March.

> Small-scale studies began in 2022. Three groups of four healthy male volunteers aged 20 to 50 received a single intravenous injection of hemoglobin vesicles — artificial oxygen carriers that mimic the structure of red blood cells — in increasing amounts, up to 100 milliliters. While some participants experienced mild side effects, there were no significant changes in vital signs, including blood pressure. Building on that success, Sakai announced that his team was accelerating the process last July. In March, it started administering between 100 and 400 milliliters of the artificial blood cell solution to volunteers.

> If no side effects are confirmed, the trial will shift to examining the treatment’s efficacy and safety. It aims to put the artificial red blood cells into practical use by around 2030.

LLMs are a tool, a very precious one if you know how to use it.

I've seen Antirez use it for hard to find bugs in the Redis codebase (videos are on YouTube, albeit Italian), I've seen Cursor refactor in a matter of minutes code that would've taken hours, correctly, I've seen security researchers leverage it to find complex edge cases, etc

My 2 cents is that developers that won't learn to use the tools will be left behind (albeit not for long imho), but also, that sales people promoting the idea that devs can be replaced equally dangerous.

I’m no fan of trump, but this was predicted by everyone in the industry . It is now playing out exactly as they said it would. If it wasn’t for trump’s change to the diffusion rules I worry Nvidia would already be down for the count. I find it unlikely that anyone can compete with Huawei in this industry for much longer. What’s worse is the best move now if for China to just cruise missile Taiwan now, and be the only place advanced chips can be made. See how excited people are to defy China when it’s the sole source of advanced chips

The description of that video includes:

> NOTE 3: After posting this video, I got a few messages from people saying that in their experience, cyanide DOES smell like almonds. So, I spent an hour tonight doing some tests, and I think the results are interesting. I did some direct comparisons and the smell of cyanide is distinctly different from the smell of almonds. However, if I EAT the almonds, there is sometimes a faint taste of cyanide. I think this is because sweet almonds still have a very small amount of amygdalin in them, which can release HCN. I don't think it's enough to smell in open air, but in your mouth it can be concentrated enough to be detected at the back of the nose. It's subtle, but it is definitely part of the flavor profile. So, while I still don't think it's accurate to say that it smells like almonds, for some people, it might be similar to the taste. To make that connection though, the person needs to a) be able to smell HCN and b) be particularly aware of that part of the flavor.

> I can smell the HCN, but I never noticed it in the flavor of almonds, so I didn't make the connection. I was even looking for a similarity and eating almonds at the same time, but never noticed it. It was only when I became very familiar with the smell of HCN that I started noticing it in almonds. What's interesting too, is that now after noticing it, I feel like I've started to associate the smell with almonds. It's no longer just a "chemical" smell and it feels more almondy. However, on the flip side, I feel like almonds taste worse and are more "chemically."

> But either way, I still don't think that saying it smells like almonds or bitter almonds is accurate or helpful. However, based on the messages I've received, some people are naturally associating cyanide with almonds (sometimes without knowing that this was even a thing and not even knowing they were smelling cyanide). This has piqued my interest and I think it could be fun to get to the bottom of this and to do a trial with a lot more people.

My take from the video's description is that some people definitely do associate the smell with almonds even though for people like Nile that may not be the most present profile. I think the association will differ from person to person, with some people definitely associating the smell with almonds while others barely see the resemblance.

People did this before LLMs anyway. Humans are selfish, apathetic creatures and unless something pertains to someone's subject of interest the human response is "huh, neat. I didn't know dogs could cook pancakes like that" then scroll to the next tiktok.

This is also how people vote, apathetically and tribally. It's no wonder the world has so many fucking problems, we're all monkeys in suits.

One that comes to mind is a participatory budgeting game much like SimCity. The game let locals to actually do their own budgets based on local info. Some much economically can be optimized if all locals knows about how the money are spend.

Of course something like that would really take control out of hands of ones on top at the budget committees in DC and fees for their friends.

Decentralization will generate much much more wealth for most people, but it will take control away from a few that are in control.

When I built my DIY NAS, the most important factor was: I wanted it _silent_. No constantly spinning drives or fans. It sits in a sideboard in my living room, and I've been using a M1 Mac for years now that is completely silent in normal daily operation, so I've become a bit sensitive to any "computer noises" and wanted my continuously running hardware to be as quiet as possible.

In practice this meant: a passively cooled Intel N100 SoC, a Corsair PSU that shuts down its fan under a certain power threshold (iirc 35W-ish), and SSD-only main storage. I did include a system fan (low-RPM 120mm Noctua) that is actively controlled based on various system temps (stays off 99% of the time), and two HDDs that sit in standby spindown and only spin up for snapshot backups once every three days deep at night.

Very happy with this system so far. It houses my data dump, backups for all my systems (replicated as snapshots to the HDDs), hosts HomeAssistant/Z2M, and hosts a local-only Gitea that keeps up-to-date clones of all my Github and Gitlab repos.

Anything I host that's available on the public Internet, I don't do from home - that's all on various VPS' or AWS. To access my local stuff remotely, I can always VPN in to my home network.

> And no, that's not some slight of verbal hand in measuring "productive" -- they are able to ship more value, faster.

Ship more value faster is exactly a verbal slight of hand. That's the statement used by every bad product manager and finance asshole to advocate for shipping out broken code faster. It's more value because more code is more content, but without some form of quality guard rails you run into situations where everything breaks. I've been on teams just like that where suddenly everything collapses and people get mad.

Exactly. That's a challenge, isn't it? We are taking a few approaches, 1) understanding who your audience is and what their pain points are, 2) What do they care about, 3) What's your expertise, 4) Few of your existing posts help us understand your writing style and tone.

In the end, idea is not to write fluff, but something that resonates directly with your target audience. Give it a try. I will send you an invite shortly.

You have to actually read more than the first line of a Wikipedia article to understand it

> formal theorem proving

You're using Coq and Lean?

I'm actually not convinced you read the paper. It doesn't have anything to do with your argument. Someone using LLMs with formal verification systems is wildly different than LLMs being formal verification systems.

This really can't work if you don't read your own sources

This has been my experience as well.

Something about the human brain just makes it very bad at observing a mocked-up screen layout and understanding how well it works in practice. Apply that to an entire application with multiple functions and the problem increases exponentially.

Experience helps speed things up. But rapid iteration with a fast feedback loop is the best practice. Design is not doing the start of the loop, it’s doing the entire loop. Repeatedly.

I don't understand what the benefit of appointments for a pizza is. I'd expect that a huge part of pizzas is sold to people who are walking there anyways. Wouldn't you loose them and they would just go to the pizzeria around the next corner? What is the benefit for the pizzeria beside the cost for operating a website and hiring/buying software (developers), because programming that website isn't really the same expertise as making pizza? Most times the pizzeria is just idle anyways. This won't change, because the customers still need to pick it up, so instead of just picking it up, they need to take time to visit a website and pick it up.

I think it's more of an anti-stupid thing.

Where I am, pharmacists will often talk to you about each first-time prescription, describing when and how often to take pills. You don't get that via non-prescription, so dosage control is a hacky fix for people that won't read labels.

It's also "smallest person" thing. If you're 2M tall and muscular (eg, more mass), your dose isn't the same as a 160cm person with little mass. The doses are for the smaller person, for safety.

I was skeptical at first, but after trying to use it several times for work (Cursor/Claude) I concluded that it's worse than I thought. Lot more time wasted for little to no results. Maybe for boilerplate frontend code or TODO app generation it's good or something?

Anyway in a couple of months I'll try again. Until that time, I guess the search result summaries are nice?

We are tailoring what we're doing for this audience. The challenge is that they appeared out of nowhere about 6 months ago and the LLMs that are used by this audience is trained on 5 years of content tailored for developers

this is not an excuse, I'm just adding color. We've made a lot of changes with tools, alerts, email warnings etc. We are in planning-mode for changing defaults and working with the AI Builder platforms. We will likely change the schema configuration and advocate for Edge Functions (serverside Typescript) where appropriate.

I think you're thinking of it a bit backwards.

Why limit your price to LTV for the offline-only version? Think of it as a full blooded product, instead of trying to squeeze it into the SaaS thinking model you've got already.

Plenty of enterprise (and such) clients wouldn't balk at all at a $500 fee. Brainstorm your target market and price accordingly. In other comments, you're mentioning the support burden - I don't think you should sell the offline version if you're not ready to lift that burden, and thus should price it in a way where this is attractive to you.

Offline versions are usually used by more demanding customers in the current day and age - the web is where you go for the user-friendly version.

According to the company's own video, there's a lot of attack surface outside of the blades.

And birds incidents with actual planes show that it's not the same reasoning as human warfare : inflicting damage to the enemy while taking none. For delivery companies it won't matter if the birds got out safely or died in the process of destroying their $$$$ drones.

You are correct but you really need to provide a source when making this claim because it sounds so unbelievable:

https://www.healthline.com/health/alzheimers-dementia/nicoti...

(Not calling healthline a source, but it has links to publications for those interested).

It's important to note, of course, that smoking increases the risk of pretty much every bad health related thing that can happen to you, including dementia. However, using nicotine without smoking might have benefits due to its effects on acetylcholine receptors.
