Ask HN: Share costs and earnings of electric vehicles chargers: profitability?
Hello everybody, I have a startup idea but I couldn't find any info about the (possible) profitability.

The idea is pretty simple: the company decides where to build a charging station for electric vehicles and anyone can contribute to installation costs for a fraction of it (e.g. Joe pays 5% of total, Hannah 2%, etc.). We take care of the installation process and routine maintenance and we get a small percentage of earnings, for instance 8%, while the remaining 92% is going to be split proportionally among the "investors" of the crowdfunding campaign (so Joe will get 5% and Hannah 2%).
I'm planning to use only 150+ kW DC chargers (ideally, they should be 300 kW to be future-proof).

Do you know what's the average margin per kWh of a charging station like that (it doesn't matter in Europe or America, I'm ready to move if necessary)?

PS: Any tips or suggestions are welcome.

If you are wondering, that 8% doesn't come from any calculation, it's just to explain better how it would work.
Whatever you decide on, don't "fake it 'til you make it", even if that has proved to be a working strategy in certain countries and cultures.
It’s not what you asked for exactly but I’ve had good success with this product

Sometimes it drops the audio channel but it’s not too bad getting it added back in.
I believe you can stream natively/directly from your PC to the Steamdeck using Steam. No need for other software.
Mainly it just means he is highly influenced by his background and history of superstition.
Very cool! This is close to being a perfect mind-map creation tool. Text wrapping would be nice. It can be done manually by adding \n, but that has to be done manually.
Err on the side of transparency, but also just ask how much they want to know (maybe during 1-on-1s). Information can create extra individual stress, and some people would rather just be shielded until bad news hits.
Finishing projects is overrated, unless you’ve never finished one then finishing a few for their own sake is worth it.

Projects are experiments. Most of the time as you work on it you lose motivation because it become obvious it won’t work or you don’t have something (skills, knowledge, mature enough technology) needed to finish it.

Only finish projects that still valuable for you or for others. Discard the rest ruthlessly, but keep them around. Sometimes parts are useful later.
I can't even get deals on books there anymore. The last three purchases I made were from eBay and gasp Barnes and Noble
Anything less than all of it is a red flag.
You are correct and Odin supports all of this.

`Maybe(^T)` exists in Odin.

Bounds checking is on by default for all array-like access. Odin has fixed-length arrays, slices, dynamic arrays, maps, and #soa arrays, all of which support bounds checking. Odin does not have pointer arithmetic nor implicit array-to-pointer demotion which is pretty much removes most of the unsafety that languages like C have.

Odin also has built-in support for custom allocators which allows you do a lot more with extra safety features too beyond the default allocator. Use-after-free is usually also a symptom of an underlying value responsibility and lifetime problem rather than a problem in itself, of which is fundamentally an architectural issue. Ownership semantics in a language in Rust does deal with this issue BUT it does come at a huge cost in terms of architecting the code itself to accommodate this specific way of programming.

There is a common assumption amongst many of the comments that if you have manual memory management, you are defaulting to memory unsafety. This is untrue and memory management and memory safety are kind of unrelated in the grand scheme of things. You could have C with GC/ARC and still have all of its memory unsafety semantics.
It's clear he can do it: the ending of Anathem ties up everything very neatly and it is hard for me to imagine any major events happening in the characters' lifetimes that would rival the plot arc they've been through.
We have plenty of money in the bank and our company is profitable. I’ve employed over 100 people during our 13 years of business. Not once have I ever had an employee say “hey man, I noticed you guys have more than the bare minimum level of working capital in the bank! How about you give me some?” Never.

If you were telling everyone you were broke, asking them to believe in the mission and endure low pay for the cause, and then it leaks out that you have plenty of cash, then yeah, I can see this question coming up.
My steam deck almost arrived before the delivery person marked it to return for damage inspection. It’s still there, but I’m almost certain I’ll never receive it. Steam support has been silent and not responded since Friday.
I don't see anyone asking for that -- just for the ability for someone other than the domain owner to pay the annual renewal fee.
> That any theory that cannot be proven should not be paid much attention to

So we continue to live our life as animals?

As I mentioned elsewhere, in Islam, we have logic, observational evidence, and the honest news to get to truth. Disregarding any one of them is nonsensical.

> Neither does it make it true. The point is if there can't be proof then it's pointless to think too much about it.

Honest news is a source of truth.

> You said there were proofs in the video

There were several arguments made, e.g. fine tuning argument and the fact that something cannot come out of nothing. Those are established, and denying them is basically denying logic.
> The flip side is then it becomes much harder for small companies to get their products approved on such marketplaces

So long as the marketplace can confirm that someone will take responsibility for product quality, I don’t see an issue. Smaller companies will be able to be more hands on with a marketplace. As in, actually having a person to communicate with customers and/or the marketplace.

The problem only is an issue for fly by night sellers that just generate new identities when a marketplace delists them. Having a little bit of due diligence added to the marketplace is a good thing for both buyers and sellers.
This is why I prefer “protocols over platforms”.

This entire thing isn’t twitters fault any more than it is WiFi’s, DNS, or TCP’s.
In my software, I display popup on hover. I display them immediately because it helps customers to discover, and it looks great with fake data. After 3 month, I add delay, because real users are annoyed with popups on hover.

I wonder how much different the products are to different people. If you subscribe to Facebook/Gmail/a lot of webapps, the UI has nothing to do with the old timers’s UIs. I think they try to keep the UI for a given generation of users.
I found the original ARM Thumb ISA very easy to use! But it’s been 27 years, time may have clouded my judgement. :-)
I like being a jack-of-all-trades too, but it is taxing.
My way of dealing with my insatiable thirst for knowledge is to pick a topic/problem/project or two at a time. It's hard but without focus I don't get anywhere.
Kind of - Suppose there are 100 ways to do a thing -- 80 of them will be wrong, 15 of them would work but have some problems, and 5 would work perfectly fine. Throwing out the 80 is science. Throwing out the next 15 is experience. Choosing amongst the remaining 5 is totally subjective.

(Those number are clearly made up, but illustrate the point.)
Also, this title is the most hyperbolic "wah company bad" bullshit ever written.
It's interesting that it simply leaves out:

The Big U

- About 7/5 on the weirdness scale of the other books. It was out of print for quite a while. Strange things happen at a thinly disguised Boston University. The Citgo sign becomes The Big Red Wheel.

Zodiac

- About 1/5 on the weirdness scale, except for the protagonist himself, who is about a 3/5. Modern thriller about pollution in Boston Harbor.

Interface

- About a 2/5 weirdness: a candidate runs for US President, aided by a direct brain interface that feeds immediate polling results and media reactions.
Because what are you going to put on the grapefruit juice label, a list of thousands of drugs that can have interactions with it? If people don't read the leaflets to their medication that's really on them.

It's surprising that people would take any medication without reading the leaflet anyway, given that grapefruit is not the only thing that can interact with them, and it's usually pretty clearly written.
I've wondered about this off white "dark" for some time. The crazy person in me thinks it might be to throw more nits at our face so emotion and attention may be tracked by our helpful webcams, aided by the Windows Camera Frame Server service.

Full disclaimer, I'm actually crazy.
So they have a financial incentive here to allow the domain to expire.
The first issue, where multiple monitors have the same vendor/model/manufacture date/serial number, couldn't that be solved by also storing which port it's connected to? That way, if you have two HDMI ports, if both monitors have the same UUID, you store settings based on port rather than UUID. I don't know if this is possible with this new USB-C world, but at least with traditional hardware, it seems like the OS knows which port a monitor is connected to.

Anyways, interesting post. It's always fun to discover how much hardware is just broken and doesn't actually correctly implement the protocols or features it's supposed to implement.
My experience has been that there are employees who don’t really want to understand the big picture and just focus on their work.

I have never seen transparency hurt the productivity of these employees. They know they can look and see the big picture any time, they just don’t bother to look:
> Or is giving too much information ... risky if an employee leaves

What is your actual risk exposure here?

For most startups the existential threat isn't competitors, it's lack of traction. There's basically nothing that a competitor could find out that would substantial hurt the startup, especially nothing that they won't find out anyways.

There are obvious exceptions (e.g. you're a hedgefund and have a trading strategy which could be wiped out if someone bigger started exploiting the same opportunity), but they're called exceptions for a reason.
I have some dells (U2414H) that can get into a really bad state. Sometimes unplugging power is not enough. You have to remove all potential power inputs including display input cables (or shut those devices down too) to get a proper reset.
Btw, this is from the wikipedia article on Equal Temperament, and I'd say it aligns with my general understanding/ expectation:

"Unfretted string ensembles, which can adjust the tuning of all notes except for open strings, and vocal groups, who have no mechanical tuning limitations, sometimes use a tuning much closer to just intonation for acoustic reasons. Other instruments, such as some wind, keyboard, and fretted instruments, often only approximate equal temperament, where technical limitations prevent exact tunings.[4]"
Yep. And - where musically appropriate - if you know which note of the chord you're playing, you can tweak the pitch towards the Pythagorean tuning and get the harmony to "ring" as the harmonics of each note reinforce each other.

This sort of hybrid tuning is common in barbershop quartet singing as well.
If they're confused you've hired the wrong people
Does pressing power while it’s unplugged expedite the process by attempting to draw power and emptying any capacitors in the process?
I take a medication for which grapefruit juice is contraindicated.

I got no shortage of warning about from the medication side (doctor and pharmacist directly and verbally, plus in written form in the paperwork and labeling).

It seems far more reasonable and feasible to put the warnings on the medicine than on the food.
You might speed this up by unplugging the monitor, then holding down the monitor's power button for a few seconds to discharge its capacitors, then immediately plugging back in and powering-on. The only reason I can see to wait 5 minutes is so the capacitors will naturally discharge, but holding down the power button while the monitor is unplugged should immediately discharge them.
Also, if you “have to” use SMS 2FA an e-sim is more secure in this case as it prevents someone from just physically pulling the sim and moving it to another device.

SMS 2FA is still a mess due to a variety of other issues, of course.

Must it mean that? Really? I had no idea! :)

It isn't always hard to know when to move on.

I think a lot of it depends on how big the exploration space is around the product you are trying to build. Building a "I'm confused" feedback button for students attending college lectures doesn't provide much roadway for exploration. You can find out pretty fast whether the product has legs.

When the product is something like "a low code developer platform", the space of building is so rich it would be worth building for long stretches of time to learn the right thing to make. The difficult part is in nailing the right product. I would keep working on something like this until someone else has won the market.

I am not judging ideas by saying one of the above is better than the other. It's quite possible discovering the lecture solution gets you to a bigger business faster and can create more impact and a bigger company. It just seems like it's easy to weigh the design space of the product, the current state of the market to figure out how long you should work on it.

> Maybe if you are doing editorial work, this could lead to controlling your workflow in a more cohesive way than docs?

I could see that happening. For the example I showed, though, as well as what you're envisioning, you'd really want to use the GitHub API to skin the experience.

And then, of course, you could do the same with GDoc.

Ultimately I don't care how it's done, I'm just looking for ways to make it easy for someone to teach others how to write and edit by presenting an orderly and easily navigable sequence of edits and associated narration.
Yeah, it's possible that all the pushing he did before made him fit enough he could pull it off.

It's just more dumb mark-manson like marketing stuff. There's no knowledge here.
That sounds great; I have had Anathem on my bookshelf for years after life got in the way just after starting it; I had planned to finally read it this fall. Your observation makes me look forward to it even more, thank you!

I would never keep anything important on the phone -- it's a Google Android phone after all -- so the strategy is simply to have the stolen SIM card locked and a new one mailed to me.

Any old mobile phone sitting around would be fine at that point, until I decide to get a new one.
Hi Bill, wasn't intended as a criticism of either, or as an observation about the syntax choices, but rather as a way of saying how familiar I am with both: I could say some things about them which are accurate, but not tell code samples apart.

RAII isn't something I happen to be looking for in a language, it kind of falls between Rust and your work in a way that I don't have a use for.

It's an interesting domain, isn't it? You'll always have people reacting from the hip to the problems C has given us, but they'll be back a couple hours later to talk about the wonders of SQLite.

SQLite got there by being careful and building tools to keep them out of trouble. I see an important role for languages which build those tools in, but don't try to replace a manual transmission with an automatic.
Did Turing have deficient intelligence levels? We are after all having this conversation in large part thanks to him.

> new Soviet Union

Any reason to think this? Did Soviet Union form by Russia invading and conquering another country? No, it was a result of fall of the Russian empire and the Russian civil war.

The conditions now are very different. Fall of Ukraine would mean political win for Putin and his acolytes, maybe another invasion later on. But Soviet Union? More like stronger Russia, a revert to the Russian Empire.
I thought Fall was outstanding; the apes, MOAB, and Ameristan parts were remarkably relevant, and the last part was fun.

> whole circumstance of people wanting you dead is not twitters fault

The hate speech itself is of course the sole responsibility of whoever created it.

Twitter is, however, fully responsible for allowing it to be spread.

Without a major communication channel which enables this hate speech to reach massive audiences, it would most likely remain isolated to a small number of people. And it probably would not evolve into a hate _action_.

The people behind this hate speech could of course reach to some dodgy places and hire professional mercenaries who might do the dirty jobs for them. But that is risky for them because their true identity might be revealed to the authorities or they might be betrayed or worse.

So what they do instead is they use a public channel, as big as they could find, like Twitter, to reach out to everyone who might be interested to answer their calling. They are counting on the possibility that maybe some psychopath with the will and abilities to do whatever they ask for will just go and do it.

The important part is that Twitter is used here as a communication medium without which the hate speech spreaders would have no major audience to pass their hate onto. The fact that they are allowed to do so absolutely is Twitter's responsibility.
What’s another good label for these types of knowledge so that we can avoid the cliche?

Is it as simple as having information and experience?

I have read everything on being a carpenter but I have never practiced, so therefore I am “book smart” when it comes to carpentry?

I guess this doesn’t really cut it because when someone claims their “steet smart” as a way to combat feeling inferior to someone else they have credited as “book smart” what they’re really trying to say is that they have knowledge that’s more useful in different situations? Or more practical situations?

The more I think about this the more it seems like claiming to be “street smart” is just saying “hey, I’m smart too, just in a different way” when you’re feeling a bit less than someone.
Most people don't think their stance is ever political. But it very clearly is here since Twitter would be directly at odds with the Pakistani government if they sided with the journalist.
There are a few reasons as to why there are different sized booleans in Odin.

One is dealing with foreign code. A lot of old C code used their own boolean type before it was standardized. And many people defaulted to typedeffing `int`. A good example of this is Win32's `BOOL` which is `int` sized, which would be backed by `b32` in Odin.

Another reason is that file formats may use different width booleans to a single byte.

Another reason is that things that are closer to the register-width are faster than byte-wide operations. So `b32` or `b64` even though it takes more memory up can be faster to deal with than `bool`/`b8`.

As for `bit_set`s in Odin, they are backed by integers and a brilliant solution to the problem of flags. They usually become a lot of people's favourite (but small) feature because of their ease of use and clarify of what they express.
Probably my favorite, edging the others out slightly... as you might guess.
Seriously? That's the reason? Crazy!
“ By February 2007, the CEO of Go Daddy reported that of 55.1 million domain names registered, 51.5 million were canceled and refunded just before the 5 day grace period expired.”

There is no story here, except “an unreliable website that some people use as a proxy to the blockchain is finally down, so ENS suggests using another service.” Critics and Twitter mobs are trying to spin this into some kind of failure of ENS or Web3.
I think you're applying too much nuance to this. Reading all the comments, I think everyone generally wants good for the author. There are just a few different ways to communicating that. Roughly they seem to be:

1. epmathy and twitter do better

2. empathy and this is what you get with twitter

3. empath and practical advice

You seem to be railing against (2). Personally I find the bone you're picking to really be besides the point. Most everyone is empathizing with the author's struggle. Nobody here is telling the author to go fuck themselves. Nobody is condoning what Twitter is doing. And certainly nobody is disrespecting the author or supporting the misinformation. So your comment really feels like a non sequitur.
Would large leaflets attached to grapefruits be somehow read much more than large leaflets attached to drug packaging?
You're a fintech startup. Your employees have already formed their own financial models of your company, and if you do not share info, they will plug in their own worst-case estimates, and leave if their models show bad numbers.

I really felt this with Seveneves, which was otherwise one of my favorites of his. That book (or series maybe...) was nowhere close to over.
This is not a matter of perspective, it is a basic fact of markets.

Market prices are quoted for small amounts. If you try to sell large amounts prices go down. If you try to sell a commodity in orders of magnitude greater that what currently exists in the world, the price drop to a tiny fraction of the quoted market price.

Back when I had two monitors, I got the same cables for both and I indiscriminately plugged them into my computer (I had a laptop, so plugging/unplugging happened ~daily). So the mapping between computer port and monitor definitely wasn't going to stay the same.
Are you saying the SanDisk listings are scams, or are those the two non-scam listings?
Please provide examples of “easily copyable technology.”

Putting together a team of competent engineers, developers, etc and having them create something meaningful is hard enough as it is. Trying to copy someone else’s tech doesn’t lower the bar all that much.
