Ask HN: Important nonobvious startup/business lessons you've learned?
Running a business is hard. Startups are even harder. A lot of it comes down to not actually knowing what you're doing wrong.

What are some important observations and lessons you've learned working at startups and running businesses that were not immediately obvious (both technical and non-technical)? Did you learn the hard way?

I would phrase the puzzle differently.

They both need to say they know, otherwise we have no reason to believe Sandy has figured it out.

And they both need to be right, which we also have no reason to believe at the moment.

That post is about specifically expression parsing for operator precedence.

Recursive descent parsers can contain Pratt parsers but they don't need to. For example you can parse s-expressions with recursive descent but there's no need for Pratt parsing.

And Pratt parsing is not the same technique as general recursive descent.

So the article you linked is about a specific subset of parsing expressions, which is useful yes, but not the same category as OP's post.
White House unveils pact with internet companies to reduce prices
I think seeing how things ended up for Russia after they opened up to the west in the 90s when the Harvard economists swooped in to transform then into a capitalist country explains most of it [1] [2] It is different for many young people with studies, who know english and see an opportunity and a high enough chance that if they incorporate themselves into the western world, they would be able to improve their place in life. But for older and less prepared people, specially the ones that lived through the 90s, probably see opening up to the west in a different light.

My whole point is that I find it interesting, and surprising, how western psychologists are taking concepts from eastern religion, completely ignoring the western religious tradition.

His description of what web dev felt like in those early days captures how I feel about VR now.

Back then it was obvious to me that was the coolest thing you could possibly learn. Still to me it is outrageously cool that I can think something up and then in not that much time it can be a website.

So whats the new magic? To me it's the idea of being able to think something up and conjour it into the virtual world too.
How far do you take this: an `inc()` function? If we get to a stage where every piece of software in the world depends on one random person's ridiculous npm module, we'll be in a pretty precarious state.

Non negligible possibility: the "ax" is also the traditionally identified root for labyrinth - 'labrys' intending the "double-edged axe", and "labyrinth" the "extended, intricate palace under the symbol for power".

This may suggest (were it intentional from Gibson) the "matrix" as a futuristic labyrinth under the same symbol of power. (You - presumably - accessed the labyrinth through a portal with the labrys, and you access the matrix through a portal with the "ono".)
I’ve had much better experience with energizer not leaking while Duracell is terrible. Searching the net for other experiences, I found some prepper forums discussing this and apparently Duracell tries to extract so much capacity from the cell they sacrifice wall and end thickness causing them to leak.

I don’t think anyone can say they absolutely won’t leak, but search these types of forums/subreddits and you find other recommendations as well.
Electric vehicles weren't quashed, they were outcompeted by a more capable product. And to be honest, that's still pretty much the case even a century later. BEVs still don't have the range or the towing capacity of conventional vehicles, and charging one is still nowhere near the power transfer of a standard petrol bowser. That's not to say they don't work for a large chunk of the population -- I think it's pretty clear that they can and do -- but petrol cars are ubiquitous because they're capable of tremendous up-time, in any environment, require relatively little maintenance, and they'll perform for hundreds of thousands of kilometers even on an ordinary maintenance schedule.

I mean, I'd like to see the world move away from fossil fuels as well, but acting like BEVs are somehow universally better than ICEVs without acknowledging the tremendous ability and success of regular cars, and the shortcomings of BEVs, doesn't really help the cause, because in certain regions, applications, and for certain individuals, BEVs really are the wrong choice. There needs to be more acknowledgement of this, and acceptance of the fact that maybe a one-size-fits-all solution won't be the future of automobile propulsion.
That is because there are "fucking websites" and "fucking web applications". These two require different skill set. Second one being a programmer.

> Imagine trying to have a relationship with your wife, by only ever relaying messages to her via a 20-year-old bikini model. This is not a ticket to a healthy relationship with someone you love.

Hmmm... I'm not sure if you should show this sentence to your wife. Plus the comparison is a bit flawed - even though your wife is probably older than the bikini model, they're both women and (potentially) equally intelligent. If you compare a C64 to a modern computer, it's more like an insect or a fish compared to a cat or a dog - they're all animals, have the "basic functionalities" of animals and can serve as a pet, but cats and dogs are much more advanced. Insects can also be fascinating however...
As mentioned the SKX is no longer produced, and the replacements for it are inferior as the 5 series has increased in price beyond inflation and are not true dive watches anymore. Orient is better if you want a dive watch in the spirit of the Seiko SKX.

The best current advice for beginners is probably on the Just One More Watch youtube channel, most watches are in the price bracket that the SKX occupied, and you will learn about micro-brands that exceed Seiko in quality, beat them on price, and under the hood have Seiko movements that are easily replaced & serviced for decades to come.

My Helm Komodo reccomended by Jodi of JOMW gets as much wear as my Rolex Submariner and at a fraction of the price. It isn't the same price or quality, but I enjoy it just as much.

the real problem is that you can't keep all those little features you'd wish for in your head, so while you are making a buying decision they don't factor in as much as the lower price achievable without those features.

Yeah I 100% feel the same! He read an entire book on "Mathematics for Machine Learning" which he found pretty easy. He skimmed over the "now let's apply this in code" sections but the maths behind it all was fine.

The pros of starting in web dev is he should be able to get an entry level role pretty quickly, it's probably the biggest market and he does find it interesting. My belief is that as long as you keep digging you'll find a rabbit hole in any area of programming and his skills will be valuable there. e.g. in web dev you can move into cryptography, WASM, encodings, color spaces, parsers, compilers etc etc. Also, while it's good to have an understanding of the maths when doing data science stuff you're not that likely to be actually using or innovating the maths and most of your time will be spent cleaning data and importing libraries? Also he's more of a pure maths abstract algebra guy and less interested in stats.

The cons of starting with web dev is that you're way less likely to need his maths skills.
I moved out of DBA work after many years working for large enterprises. Databases had become more of support model. There were very few new databases you were able to contribute to. Either it was an off the shelf package where the database structure, configuration and coding came from the vendor or platform as a service.

The puzzle doesn't state whether Sandy has figured it out because that information is not necessary to figure out the solution. We can infer that she has (under that implicit assumption that she is a perfect logician) by the fact that we know less than she does and still have enough information, though. As for that last part: we also don't truly know that Peter isn't lying just to mess with the puzzle, I guess. That is another implicit assumption.
Not sure I'm a fan of the hype cycle, it's pretty vague.

I think the thing to remember is that tech people see through all the hype before everyone else. People who are close to a tech will be able to tell you the endgame before someone who doesn't, because they understand the constraints of the system.

Being on HN is a bit like time traveling, you can ride on everyone who has zoomed forward into the future.
I'd just like to get this in before comments get on a roll. I learned about Russian culture during the Cold War, from professors who were Soviet emigres and the children of emigres. The image of Russian sensibilities I developed from their stories of everyday life in Russia was rather different from the brutish stereotype in popular culture, at the same time more empathetic but also scarier. Since then, I have always been disturbed by the dehumanizing portrayal of Russians in the West. Now with the war in Ukraine, that popular tendency has exploded into a vicious mania. Russia is full of people who love their family and are just trying to get through life. If 80% support Putin even with all that is going on, something is going on with them that Westerners clearly don't appreciate.

Things suddenly start making sense when you look at them from this point of view.
The post shows how parsing functions call each other so it isn't really so far off:

fn parse_money(&mut self) -> ParseResult<MoneyNode> {
let currency = self.parse_currency_symbol()?;
let amount = self.parse_amount()?;
return Ok(MoneyNode {
currency,
amount
});
}

you're reasonably experienced with Linux already. It's not for everyone, obviously, but that's okay. "Easy" is one of those terms that's hard to really say much about in general terms, because it really depends on the audience (both objective skillset, and subjective preferences and expectations).

It also doesn't strike me as particularly unrobust; one of the virtues of being simpler is that it's easier to understand and figure out what's going on. As an example, setting real-time priority on my system is currently broken, and between Pulseaudio, rtkit, Polkit, and dbus I can't figure out why. For my desktop, I'm actually just fine with just always allowing pulseaudio to set real-time permissions without a rtkit/polkit check so I don't really need these capabilities, but they are preventing my system from working correctly.

I have been cooking since 15. At one point in my life I wanted to be a chef, but ended up in CS and now in engineer.

Last year, I saved up enough money to open a cafe in India. Soon, I realised how hard it is to be a chef. Person who is the head chef at the cafe works almost 10h a day, 7 days a week. You have to be on your toes all the life, deliver consistent food, deal with stress, deal with customers returning food, have no ego, make decisions on the stop, planning things ahead of time, foreseeing things short term and long term.

Being a good home chef does not make a ready to pursue chef as a profession. It is pretty brutal.

The very word "loving-kindness" was devised in English as a translation of the Hebrew chesed ("charity") e.g. in Psalm 50/51: "Haue mercie vpon mee, O God, according to thy louingkindnesse" (chesed). So in Biblical and Christian tradition God's mercy is ultimately seen as an aspect of His loving-kindness.

You know, I’ve never really thought much about the difference.

In my head, morals usually equates to acting within some set of conduct guidelines laid out by society or religion.

Ethics, is the same but instead of not (e.g) just shooting someone because it says not to in some book or law, I do it because I somehow know it’s harmful.

That’s a pretty awful explanation. I guess I mean, I somehow draw the distinction between these terms based on where these “seem” to come from.

I think most people have the intuitive ethics, morality is something we pick up.

Of course, that’s probably complete nonsense ;)

"Time. I had nothing but time. Endless time. At first it was madness. Then enlightenment. Then madness again. But perhaps it was a gift. I could see the life of time. And as I watched the life of time, in all its fleeting, terrible light, I wondered: 'Had I lived? Was I just the object in another story? Was that all I ever was? Could I be more?' I had nothing but time. And still, no answer. Time without purpose is a prison. I have glimpsed into the mind of eternity. Perhaps the mind of God. And, found nothing but silence.
