Ask HN: As a business-focused co-founder, what hard skills should I study?
In my current startup, I'm the de facto "business" co-founder. I want to be investing time in learning hard skills that will help us now and in the future so that I can be better prepared.

Below is the list I have so far. What's missing? I'd also love to know what you recommend I use to learn each topic.

1. Financials
2. KPIs for different areas of the business
3. Hiring
4. People management
5. Fundraising
6. Strategy
7. Marketing
Very impressive, and works well on mobile (iOS). Congrats and thanks for sharing.
My guess is that either the Ministry of Defense or Putin ordered a hit on Prigohzin. It either failed or he got wind of it.

The best way to ensure his own safety at this point is a coup.
I have rarely seen large groups of humans be accused of excessive consistency over time when it comes to matters of fact and science.
> Why would they want to?

I don't know, when the board changes you look for openings. On the military side, I would use the distraction to extract battlefield gains. On the diplomatic side, maybe Putin is willing to give up more, now, than he (or his successor) will later.
This is great - I will definitely check this out.

I'm curious - have you been using this for long? Have you noticed any code which this flagged and which you thought it was being too strict? I feel like I would want this flag on all of the time, but I'm curious if there are edge cases that I have not considered but maybe you have experienced.

In hyperbolic geometry it's hard to even have x,y coordinates at all. Once upon a time I looked at the source code of a hyperbolic 2D game; can't remember if it was HyperRogue or something else. It recorded your position as something like a binary representation of a path down a tree from the origin point.
>A lot of the reasons why old versions of Windows ran apps instantly is that they excluded the entire non-European world and did not even attempt to deal with complex languages.

There was Windows 3.2 in 1994 (not to be confused with "Win32", despite the name of the HTML file):
http://toastytech.com/guis/win32.html

Yes the western versions of Windows at the time didn't include support for Chinese (etc.) language. But there is really no reason why they should - if the user's language can be represented in an 8 bit codepage, why should they have to pay any price in performance for something they will never use?

Conversely, would a Chinese-speaking user prefer an operating system designed to support all the other languages that exist, with an implementation that is likely not as specifically tailored to their requirements?
putting people in jail for doing drugs doesn't do much for their children or their health either.

I also don't see why it has to be all one way or the other. I agree that people with dependent children have no business taking risks with drugs. like you say, this creates a mess other people are compelled to clean up.

but what if a person doesn't have children (or successfully raised them to be independent adults)? as long as they pay whatever taxes they owe, why care what they do with their time?
That's not the way contracts work... the wording very much matters. RH might have a semantic argument, but it's a very defensible semantic argument.
Related tangent: I predict that certain political movements in the US and Europe will implode if the Putin regime does. Would love to see if I'm right. Making popcorn.
It's easy to call something a psyop, but have you got a specific reason why this would be done? It's not like that would confuse their enemy in any way, same areas need reclaiming anyway, same troops can be observed. "There's internal conflict" has been known for a while and unless there's practical impact, it doesn't seem to affect what Ukraine needs to do.
"Get out!"?
Not a peep about the spate of book bannings, attacks on free expression by queer people, attacks on people not suitably gender conforming in bathrooms, and attacks on queer events in this lengthy piece on the attack on free speech.

Which makes this line especially bizarre:

>> "It’s why people can’t read books anymore and why, when they see people like Russell who don’t fit into obvious categories, they don’t know what to do except point and shriek, like extras in Invasion of the Body Snatchers."

When you realize he's not talking about any of these real attacks on freedom.

I'm not surprised every submission under this domain appears to be hot garbage.

In a comment you say you're a tech lead. It really depends on what the meetings are, and let's put them into 3 buckets, from least latitude to most:

Are they regular meetings where you're the representative for your team or function? In other words, the types of meetings that all other tech leads also attend -- whether they're the only tech lead present (weekly team meeting), or lots of other tech leads (department tech lead meeting), or your weekly 1-1 with your manager, or your monthly 1-1 with each other team member? Because these are just part of your job, full stop.

Or are they specific one-off problem-solving meetings with 2-6 people total that actually need your input? Because these are generally part of your job as well, especially as a tech lead. If you find yourself regularly contributing nothing though, you can push back or suggest a non-lead team member instead. But really you should bring this up with your manager because you're surely not the only one having this problem, and saying no to these meetings could negatively impact you if your input really is required and you merely find them inefficient.

The last category is one-off special meetings to explore new ideas, build relationships, get feedback, talk about company culture, learn things, etc. These are where the company wants to have a wide range of people present but your specific absence may not be noted. On the one hand, you can try just not going and it might be totally fine, and if anyone asks just say you were fixing a time-sensitive bug (important: don't respond to these calendar invites, so they don't say "Yes" but they also don't say "No".). On the other hand, if your manager/peers are usually there and they start noticing you never are, you might develop a reputation of not caring about the company, not being a good company citizen, etc. You'll have to decide if it's worth the reputational hit and whether that could affect promotions.
Navy subs literally deform while diving. If you tie a string tight from one bulkhead to another (from left to right, not front to back), as you dive, the string will go slack and you can tug on it. Destin (smarter every day) demonstrates this in one of his submarine videos.
I think he might also mean the claims that Obama was born in Kenya and even releasing his birth certificate, the original, wasn't enough even though this wasn't an issue for other presidents
It also wasn't built with parts from camper world and cheap Xbox controller knockoffs.

NASA actually had a strong focus on safety. They just went about it the wrong way, calculating safety ratings backwards.

Considering the pressure vessel of this sub was only meant to handle 1300m as per another article, the way it survived 50 dives at 4000m is pretty amazing though.
We're working on em! Just launched today but check back in or give me your email and I'll let you know when we do. Hopefully in a week or two. Users are making moves!
Serious question though. Doesn't look very good if they intentionally took the website offline.
Hyperbolic is fundamentally different geometry. The circumference of a hyperbolic circle is exponential in the radius. Yeah that's right - add one unit (or at least, a fixed number of units) to the radius, and the circumference *doubles*. If you're thinking about using this geometry you should go and play HyperRogue to get a feel for it.
When you're talking about 6,500psi of pressure carbon fiber is cheaper than titanium. Also the fact that they skipped non-destructive testing, void checking, nor did they have the hull inspected after each dive means they were certainly cutting corners.
The DMCA is very much a shitfest designed to serve large companies with boatloads of IP. The takedown notice procedure negates the benefits of "safe harbor", which has been pretty thoroughly weakened in other laws and rulings as well, but the harms of it are miniscule compared to the anti-circumvention sections, which has reshaped practically the entire economy to serve corporate power in a way that not only disadvantages, but often actively harms most individuals, especially if you believe that loss of freedom or livelihood is a harm

> Especially accessibility really isn't as hard as people sometimes make out on this forum

Just to make sure I'm not being one of those people: What AccessKit [1] has now, across Windows, macOS, and Linux, took roughly six person-months of work. We still need to support more widget types, especially list views, tables (closely related), and tree views, but we do already have text editing covered on Windows and macOS. Perhaps it helps that I'm an accessibility expert, especially on Windows. Anecdotally, it seems that implementing UIA from scratch is daunting for non-experts. But I guess in the big picture it's really not that hard.

And Ukraine has the convenient position of just telling Wagner forces something along the lines of "you're a bunch of war criminals, but anyone observed retreating into Russia isn't going to be pursued" if they want to let the infighting do the maximum amount of damage.
Challenger Deep is exponentially more difficult than this - 10km Vs 4km so over double the pressure.

While it may still be an entirely unsuitable material for 4km, not being suitable for 10km doesn't prove that.
Right, I never claimed there are not tradeoffs.... I said it is a factor. As such, if you assert that my post said you can't do burns because of pollution, than you have strawmanned it to the weakest possible stance it could be, in spite of my clearly stating that is not my stance. I have literally said the opposite of that, in this very thread.

More, it has not been established that it is too far into the "no pollution side at all." Do you have evidence that it is pollution regulation that has caused no controlled burns? Noting that I can bring up plenty of easy evidence of folks literally doing small scale controlled burns.

I don't think you all are doing it on purpose, but this is a dog whistle tactic to pull in a lot of anti regulation folks to yell about things.
> They replace unhealthy CSs very quickly and efficiently

Maybe fixing the bugs so that they don't mysteriously get ill would be a thing to pursue?
A well-thought article

> One of the big themes of 1984 was the reduction of everything to simple binaries. He described a world where “all ambiguities and shades of meaning had been purged,”

> A political movement has long been afoot in America and other places to reduce every political question to simple binaries.

> This is straight out of Orwell. Instead of having “ambiguities” and “shades of meaning” on Covid-19, they reduced everything to a binary: vax and anti-vax. It was the same with someone who shared true research about the efficacy of natural immunity or suggested that the virus came from a lab. It all might be factual, but it was politically inconvenient, something they called “malinformation.”

I resent your comment, it's very distasteful.
Why would an asynchronous messaging platform worry about real-time messaging? It seems rather counter to what the platform is meant for.
I really don’t know much about the FSB. How many forces do they have? How much equipment? We have seen that they’re capable of carrying out extraterritorial assassinations and have kept Putin in power for decades by infiltrating and breaking up and political opposition. This is a different story: a full-scale military coup by a private army.

But it remains to be seen whether or not Prigozhin would try to topple Putin or merely the army leadership in order to put himself in command of the war. The video statement I saw him make [1] would suggest he’s intending to gain control of Putin but keep him as a figurehead.

Axis doesn't sell to customers directly (not even to businesses), they sell exclusively to distributors that in turn sell to well-stocked online computer stores from where you can buy them like any other tech product
Noticed this today, too. I turned on a computer I haven’t logged in to in 2 months, and clicking a channel took at least 5 seconds to open/load. And then it worked normally after that.
Are you really comparing this to Anime.js? I don't know if it's satire.
Is 2x abstractly reasonable in this context? My [probably flawed] understanding in contexts such as hoisting is that safety margins of 5x are considered a bare minimum. Even crappy "Don't use this to lift things" chain is sold with 3x margins.
One thing I'm curious about, as someone who knows nothing about the engineering of these things... why wouldn't anyone building something like this choose to over-pressure the sub once people were inside it and it began descending? Wouldn't 2 atmospheres inside represent a 50% reduction in the pressure differential on the hull at depth?
I second the recommendation for Axis cameras. They have LAN only streaming options built in.

You can find older used HD resolution Axis cams fairly inexpensively on eBay. They have a lot of different chassis/lens configurations and a lot model numbers so some research might be required to find the right camera configuration for your desired use case, especially if searching through the used market for models that have been discontinued by Axis.
> What concepts exactly can’t be verbalized?

I would like to explain, but I can't quite put it into words...

:)
I had to check if sound travels fast
enough. Just about, yes. Half a millisec to go 1.5m.
Worse, going from 1 atm down to 400 atm of pressure is a much larger difference than going up to 0.2 atm.
How do you sign things? Printing? Most signatures are in cursive, so I wonder how someone signs things without having learned it, or how they know what other people's signatures even say.

Many wedding invitations use cursive writing that is hard enough for cursive readers to read. And then there are birthday cakes that are often written in cursive. Lots of store signs have the word 'free' or "Today only!" (or whatever) in cursive. Chances are your graduation certificate has lots of cursive writing on it.

How about all those cards that say Congratulations! in cursive?

Look at how many brand logos are in cursive. Kleenex, Ford, Cadbury's, Barbie, Fender, Kelloggs, Coca Cola, Instagram, Vimeo...

Understanding cursive is a basic skill because it shows up in so many basic places.

Everybody seems to be concerned with technical failure. Can we rule out the human factor? What if somebody fired a bullet from the inside? Would it withstand?
This needs boosting. I mean, there's actual underwater video of this thing that has been happening lately in e.g. Portugal.

What kind of reaction people expect from this hackernews post?

Anything that goes against the dogma will get shut down?

What's the veracity of this article to begin with?

In the age of digital transformation, what are the chances we are reading fake news from the Ukrainian front?

They attack each other? well, if they killed some russians and stole their missiles, it's easy to create confusion on the adversary camp, capture a general, train a model and spread fake news with deep fakes etc etc

Until we get a proper source, we can only speculate

Few days ago reports were saying that the counter offensive was a complete failure, so who to trust? where is the truth?
> Flipside, allegedly it is nearly undecipherable

It's readable - though obviously you're going to need experience in RDBMS theory (Codd's paper, etc) to grok it.

It is very verbose, though.

Fortunately, the only people who need the ISO SQL spec are the vendors: the people writing SQL engines and tooling: it's next-to-useless for people who are designing databases or writing queries against them, chiefly because no RDBMS implementation, ever, has come close to implementing the full specification, and everyone has their own extensions to SQL - so all the vendors put out their own documentation and the world's largely been happy with that for the past ~40 years that SQL's been relevant.

It's not too hard to find the standards in PDF form if you know where to look - and as someone who does a fair bit of SQL, I'll say I've only ever referred to the standards to back-up my more controversial posts on StackOverflow.
While I've never done this, I have always wondered about it. It honestly seems plausible. For most of my career I've actively ignored most of my email except for a few filters and no one ever even mentions it.

I can imagine a world where you even say "if you have to fire me I understand".

Would people care though? I can even imagine it becoming kind of a running joke.

Would love to hear from someone who attempted this.

Do we really expect Putin to manage a peaceful transfer of power? Devil you know, and all that.
> Why we need a dedicated CPU and DRAM attached to flash memory. You can garbage collect and wear level in your OS if you want to.

The thing I don't get is, the chips are all commodities, and it's not like soldering them to a board is rocket science. Why isn't one of the companies that makes fully-specified inexpensive RISC-V chips selling one attached to some commodity flash chips and an NVMe connector? Include some minimalist open source firmware that offloads most of the work to the host OS and let the Linux community figure out how to make it better.

At minimum it should allow you to undercut the existing competition on price because you're using a less expensive controller and no DRAM, and in a few years the open source drivers could have enough advantages over black box devices that nobody wants to buy anything else.

I'm trying to add more info but it is (as one might expect) quite chaotic right now.
I'm not sure how it's done in California, but in a lot of places, they do something kind of similar to this. In areas with a very large buildup of fuel that puts trees at risk of burning, they will cleacut a ring around the planned burn to keep the fire contained.

However, they would not normally log all the trees within the burn area. The goal is to preserve the trees and clear out the fuel that has built up at the underbrush level. After the burn, mature trees help suppress further underbrush development.

When trees are removed, it leads to a lot of secondary growth, which both promotes fire and is heavily susceptible to being killed by fire. This is fine if the goal is to maintain the area as a more open field-like space via frequent controlled burns (which we honestly should be doing more of; meadows are highly ecologically valuable), but if the goal is to maintain it as forest, then you don't want to remove mature trees.
Yes 2022 launch date would be difficult. Some type of gravity field manipulation to create a closed time like curve would be required.
Well, in this case we are talking about the Photovoltaic Sector within the PRC.

This implies that this is a microeconomics problem, not a macroeconomic one. This means that metrics like GDP PPP, HDI, etc are completely useless when investigating a subsegment of industrial production.

If I was analyzing the Photovoltaic sector, I'd probably look at

1. Current TAM, Future TAM, TAM growth rate (both past and present)

2. The price of the inputs used (wafers, polysilicon, cells, modules, labor, R&D, tariffs, subsidies)

3. The growth of comparable manufacturers globally

4. Adjacent markets/segments (if I am specialized in solar wafer manufacturing tools, can I potentially pivot into tools for IC wafer manufacturing)

This is a non-comprehensive list, but in general I'm not surprised with a collapse in the price of Photovoltaic Cells.

This was kind of the whole point globally of spearheading the industry - it helped build domain experience or subsidize the adjacent semiconductors sector as well as helped countries like the PRC and the US pivot away from foreign ONG dependency, and is why countries like Vietnam, Malaysia, and India also invest heavily in the sector.

The way Wolf Hall tells the story, he also learned about bookkeeping/banking in Italy which combined with his (later?) legal training let him run rings around the other powerful public figures of the time.

Wolf Hall is worth reading for many reasons but one of the interesting/unusual aspects of the novel is that its kindof answering 'what would happen if a smart fairly ruthless person with fairly modern legal/administative/finance skills was sent back in time 500 years'
