Thank you for saying this.

The fact is, as a black male, I sometimes feel prejudice against black males while walking at night. And I'm someone who is affected by that very same prejudice. I see all the same media as anyone else, which constantly portrays black men as a menace to society.

Is a random black man actually more dangerous than a non-black man, in real life? I have my doubts. But for argument's sake, let's say it's true to a slight extent. That still means a given black man bares very little actual risk. Yet, what sort of psychological damage is done to us by being repeatedly subject to this treatment? It's an invisible tax we pay. I've been fortunate my whole life for so many reasons, but I have my own stories, like most other black men I know.

I feel other types of prejudice too. I think step one is knowing this, step two is empathizing, and step three is advocating.
But that never in reality happens. All the forks of Bitcoin or Ethereum are mostly irrelevant. The majority will blindly follow core devs in both cases as have been proven by a long series of forks that became irrelevant very quickly as most people stay with the core version (Bitcoin or Ethereum Core Devs).

Ask HN: Basics of startup business accounting?
Hey HN,

I have a decent grasp of marketing and product discovery/development, however I feel quite week at the basics of business finance and accounting, preferably in the post-series-A startup universe.

Are there any short and sweet resources out there on the web that you would recommend? I know Udemy and other MOOCs have courses on it, but I'd rather get a compressed "for hackers" version of the subject without sitting through hours of chatter.

Thanks in advance!

Yeah - that is how it works! Blockchain can be solution to anything - you just need the definition of blockchain to be broad enough.

It is an empty signifier.
> But if inflation is 3%, you're probably paying 3% (or more) interest on your loan.

Not only that, leverage is risk. Buy a home in 2006, or in a city on the decline, and you may lose everything you put in. Leverage multiplies the losses as well as the gains.
I usually spring for a hotel in Narita for the last night in Japan. While probably not the most charming place, it's a town in its own right and good food can be had so you're not dependent on the hotel restaurant.

Going to Tokyo for the evening is mostly out, since the train connections at night are terrible and a taxi will hit you with 200 - 250$.

Nevertheless it definitely beats the Shinjuku early morning rush hour with heavy luggage experience, which really is pretty fucking dreadful.

"You hold a 5 percent fixed-rate 30-year mortgage"

Yeah, no. I know that many people may have loans of this size and I never understood it. And it is of course a reason for high prices.

When my parent's bought a house a typical mortgage was paid off in maybe 10 years.
I myself took a loan of 12 years. And not at 5% percent! The real rate is about 0.2% at the moment (and has been 1-2% during the ten years I've been paying).
After paying this reasonably sized loan I can buy another house with a similar loan.

I have also heard of 60 year loans! (eg. sweden). Now that is indeed stupid and throwing money away.

That's overstating it. In general, the failed attempt helps propagate the good idea, and helps that idea find a better execution in the future, as well as being a cautionary tale.

As someone who 1) knows a few functional programming concepts, 2) hasn't programmed extensively in a functional language, 3) would like to get productive fast (in web development), but also 4) wants a language for the long term (think general purpose, decent momentum), including for academic interests... Is there a language that fits all these requirements, or am I asking too much?

Elm is too limited, Haskell seems too convoluted, unsure about F# and OCaml, don't know about good alternatives.

I've been considering PureScript because it seems to strike a balance between features, JS interoperability and skill transferability, but I'm still a little afraid of it being unnecessarily complex for my next short-term projects.

I've only now started considering ReasonML, but am I wrong to think it's much closer to the "get productive fast" side than the "long-term investment" one? Not to mention its JS-like syntax, which I admit I have a distaste for.
I’m not following the leveraged point - why is a 3% increase equal to 15% growth?

In the Bay Area HOA fees plus property tax add up to nearly my existing rent even before considering a mortgage which has made me nervous to buy. I’d be banking entirely on the upward trajectory of the market for it to be a better bet than renting with roommates.
I recently did the math on this myself, I just sold my Condo and right now I am renting while looking for a house. I have all cash so I can ignore interest rates which makes it easier, I also have a pretty good wealth manager so I have a pretty good idea of what my return will be if I invest the money in stocks and bonds and rent rather than buying a house. For me, renting comes out ahead strictly looking at the dollars over time, by a pretty good margin.

But, guess what, I am buying a house anyway for one very simple reason. I want to own my house and be able to do whatever I want. I am getting a place with a big basement and it will be my dream lab, with all my computers, 3D printer, test equipment, soldering station and so on. I could never set something like that up in an apartment. To me that is more important than the money.
A few notes:

Deductability of interest (and property tax) is a lot smaller than it was before with the new tax code. On a $1M house for a married couple, you might get ~$9k back but (in CA) that's offset by the $12k (EDIT: likely non-deductable due to SALT max) property tax.

Anyway, using my own calculator (https://medium.com/@usaar33/an-up-to-date-buy-or-rent-calcul... with other defaults), the situation you describe only works if the market is offering a price/rent ratio of 14 (years) or less (which is true in much, but not all, of the country).

Regardless, there's a lot of added costs to ownership: property taxes, HOA fees, loss of leverage as you pay down mortgage, closing costs, etc.
I wouldn’t worry too much until there is an actual use case, and if there is a use case, then why worry?

I work in the Danish public sector, and we’re sold tech by consultants who hype politicians and upper management, both ares with very little technical understanding. But while they don’t understand what tech is, they do understand change management, and if there isn’t a proven benefit, they won’t buy the hype.

We’re doing a lot of RPA these days, and from a technical standpoint that’s really fucking stupid. An API would be a gazillion times better than a screen scraping macro. In reality, however, we run 370 different IT systems and the truth is that a lot of them won’t have a decent API in the next 20 years, if ever. So while RPA is really stupid technically, it has immense value on the business end because it automated shit we couldn’t automate otherwise.

The reason I mention RPA is that I asked my engineers if it was worth looking into about 3 years ago, and they gave me a straight no. So we didn’t pay it attention until our CEO asked me what RPA projects we were doing after having attended a Deloitte conference on the business application of RPA in the public sector.

Blockchain doesn’t have a use case, and that means it won’t sell, even if it’s hyped to non-tech people.

You do see a few public block chain projects, but they are mostly poc’s that never lead anywhere and they are all run by in house enthusiasts, who were “allowed” to “run with it as long as you keep doing your regular work as well” because allowing your workforce to play with their ideas is motivational, even if it’s really just a waste of time.
Thanks for contributing; that's very informative and insightful.
How burnout drove an entrepreneur to help 30,000 people in Southeast Asia
Several bad assumptions in the article
1: 8% a year in the stock market is a very old number that you only achieve if you go back to the Great Depression. It’s actually under 7% if you take the last 30 years as your baseline
2: The local real estate market matters a lot. Crunch those numbers again for San Francisco real estate and you will have beaten the S&P by at least a factor of x3 in the last 30 years. Similar for NYC
3: not only is the real investment leverage with deductible interest and downside caps, but the capital gains are also waved on the first 250K/500k (unlike stock market gains)
4: you will not pay 5% on any loan. More like 3-4%

You can claim that the SF gains are a fluke, however there seems to be a general trend of most of the high end employment opportunity concentrating in a few large cities across the world. Those cities are outperforming the overall stock market consistently
VCs raise money the same way startups do, only with more regulation. For that bucket of money they likely presented a thesis for how they would used to invest in the ML/AI wave. Investors have rights if the money isn’t used they way they were told it would be.

VCs raise money from fund managers (sovereign wealth funds for example) who also present a thesis to their stakeholders for how the money will be managed.

Depends on the timing but I think VC focus on ML is a good indicator of where smart money thinks the money is going to be made. But there are a lot of people that catch a trend in the tail in, I don’t think we’ve gotten anywhere close to that for ML investments.

For some lithium battery chemistries (eg. LiIon) they have a limited shelf life regardless of number of cycles (which is why, for example, phones and tablets tend to drop sharply in battery life after 2-3 years regardless of level of usage). I'd be curious to know how the Tesla packs perform in that regard.

WSMeter: Performance evaluation of Google’s production warehouse-scale computers
You have $100 - you buy a house worth $500. House goes up 3%, it is now worth $515. You invested $100, and have $115 in equity. Growth 15%. (that is ignoring other costs, obviously - just an attempt to explain the maths).

That is the power of leverage - you grow on the bit you own as well as the bit you owe.
What the article describes is called an "expert system" and is what AI in the enterprise used to look like.

Basically, you try to capture the instinct of a great salesmen by formalizing it into computer logic.

Often that's done with rules like in the article.

It works good, but has its limits. The finer reasoning of human judgement are often not expressable, people don't know why they made that decision. Making it hard to capture. And human also have their limits. Too many variables, too much noise, too much data and they won't make the best prediction/decision.

That's when ML shines. Instead of trying to encode an expert's intuition, instead you let the machine develop its own intuition, itself becoming an expert through training.

The downside is it now similarly becomes challenging to formalize the machine's intuition. Why it made a given choice is no longer easily apparent.

I do think expert systems still have value. Especially when you lack the dataset to train a machine expert.

> Financial calculations ignore the leveraged nature of buying a home. Small increases in property value are multipled relative to your initial investment.

This is absolutely true, though it is also hard to account for that risk, which also leveraged the down side:

Toronto is experiencing a 30% drop right now which probably means that for the last 3 years of home buyers, they are all having a mortgage higher then their property value. They actually have lost a lot of money and paid interest for it.

> - “I don’t want to pay those high real estate taxes.” Renters still pay the same real estate taxes, it’s just baked into the rent and can’t be deducted from taxes.

This is a nuanced economic topic: property taxes don't transfer to rent quite right. Rent is not that elastic to tax changes, while property values are. The rest of the comments you mention about tax exemption for being a homeowner is true and pretty ridiculous.

EDIT: looking into toronto's case, it seems to particular about restrictions or otherwise. The point in general is that the leverage works both ways, so there is exposure.

Understood! Thanks for explaining!
What makes you think Bitcoin will remain anonymous? At the end of the day, nothing prevents banks from end-to-end encrypting payments and thus making our bank transactions anonymous. The reason they don't is because people don't care, not because "blockchain tech" is needed, whatever that means. On the flip side, if we as a society decide that anonymous online payments is a net negative for the good of society, then making bitcoin mining, trading and acceptance illegal basically kills it. At that point, literally only criminals would use it, and even then its use is debatable because if the speculative use case is dead and the developers are all anonymous or in jail, I don't think bitcoin's value could hold long enough for a criminal to buy it, send it, and then sell it successfully without losing a significant amount of the initial value.

Anyway, we're both speculating here. Like I said, if "science" is going to be brought to the table, I'd like to see the science backing your claims. For example, do you have research showing that no trust is required to make bitcoin work? Can the system survive without us trusting the developers, chip manufacturers and miners?
> What about the interpretation that I don't want to be subject to price fluctuations of a single object that represents a large fraction of my net worth?

That only makes sense if you bought the house in cash or if someone is willing to loan you money at 4-5% to buy stocks. Investments aren't zero sum when the government is effectively underwriting your mortgage.

This article is total woo. Sorry.
The entire car is revolutionary. It’s like the iPhone - there wasn’t a new scientific discovery behind the iPhone but the sum of the product was clearly revolutionary. That much was obvious to anyone who picked it up in 2007 and had even the slightest ability to imagine a mass-market user.
An article about unhealthy desire for prestige has surfaced on HN, a subsidiary of a very prestigious VC firm, a site with clever upvotes and, most importantly, karma system. It strikes me as ironic.

For what it's worth, Toronto salaries have a pretty different statistic on hired.com: https://hired.com/state-of-salaries-2018

Speaking from personal experience, I've seen salaries ranging from 100-120k CAD with 4 years of experience. Rent price increases as of late seem to be affecting much of the costs as well. YMMV. Tax is comparable to California as well. It's not as lucrative as USA, but public schooling is very strong in Toronto.
Considering you mention not having programmed extensively in a functional language, I'd say you should pick a language with extensive documentation for beginners. I know you dismissed it, but many people have put a lot of time and thought into designing materials for learning Haskell. In particular, I think most people recommend the Haskell book[1].

That being said, all the choices you list (Elm, Haskell, F#, OCaml, PureScript) are solid languages with good communities. The core languages are similar enough that if you start learning one, the things you learn will transfer decently enough to all the others.

However, you do benefit greatly from understanding the issues and the challenges of building software at a much less sophisticated level, so you can speak the same language.

The lesson you should have learned is to make the generic landing page actually describe the what the product attempts to acheive! You have just had a load of inquisitive wanting-to-be-impressed HNers descend on your page and nobody knew what the thing was about! :)

Publishers, educators etc also need to understand what the value proposition is for their users.

I also think the page ought to be written in longer sentences. The current silo buttons aren't even making it clear that they explain more.

So, suggestions:

You just have to take the few sentences from your Individuals page "Reading on-screen can be tough on your eyes, especially if you have to do it all day long. We’re here to help. BeeLine Reader makes reading on-screen easier, faster, and more enjoyable." and put that on your landing page instead of "A New Way to Read."

Now change the "(choose)" subheading to "perspectives:", put it lower nearer the buttons instead of near the description, and perhaps left-align it.

Change the buttons from meaningless colours with labels to something descriptive like "for you the user :smile:", "for the publisher $" and "for the educator :graduation-hat-icon:".

Voila! good luck!

But in this particular case, it was a corporate VC, investing their own money.

As sibling comments note, not necessarily due to appreciation being baked into housing costs.

Additionally, the owner and renter may have different risk tolerances where in the renter is comfortable putting cash in the stock market, the owner might want lower-risk, lower-yielding assets.

Finally due to tax distortions, the owner may have a better deal on their own house than a prospective new owner could get.

The Bay Area is an example where renting is much cheaper than owning: https://medium.com/@usaar33/why-you-shouldnt-buy-a-home-in-t...
