5/50/500k Startup Rule
5/50/500k Start-Up Rule

My cousin emailed me recently the subject read “Need Advice” and the mail was about him wanting to do a start-up. He is part of a large tech company and been there for 4 years.

The challenge was he had two ideas, and he wanted my help on how to chose the best idea among the two.

We met and he took me through both the ideas - I asked him the usual questions - TAM, Competition, Penetration, Competition.

After 4 beers and loosening up a bit I told him screw all that, and what was the idea he felt very strongly about? He said it is like asking his mother which kid she likes the most… So there we were, not sure the way forward…

After a couple of more beers, i thought i had a start-up rule for choosing ideas..

1. Develop an idea with 5k Investment - define metrics

2. If the metrics checks out, Invest 50k more to build the idea further.

3. If the metrics check out you are ready for a 500k investment from an investor..

What according to you is a good rule to evaluate ideas quickly?
> Public transportation in San Francisco doesn't suck.

Moments later...

> The BART sucks.

That's a bit of cognitive dissonance right there. It's understandable given utopian transportation won't arrive overnight, ESPECIALLY in San Francisco. When I first moved here, I was totally blown away by the lack of a major highway connecting the North Bay to the South Bay. Yup, you gotta take Van Ness!

The fact there is massive inertia on infrastructure change in San Francisco is part of our moral system here, like it or not. That doesn't make me, or others like me, hypocrites, nor does it mean others aren't working on solving the problem. Personally, I'm working on implementing morality in other systems in which I have experience.
They could certainly petition the government for the return of money that couldn't be tied to anything illegal. But is the potential demand of return of money a hindrance for the government to auction of the Bitcoins? If anyone demands their money back, and the government agrees, or is forced by a court to pay it back, they can do so without holding BTC in the meantime.

Presumably they've made an assessment and come to the conclusion that either the percentage of assets held that belong to customers of SR that said customer may have a claim to is small enough that it's easier/cheaper to deal with that if/when anyone makes a demand than trying to sort it out before auctioning off the BTC.

Especially given that presumably very few customers of SR have only bought/sold legal goods, and so presumably most of them won't want to identify themselves.

The tone of the article is not relaxed, however I'm a bit perplexed of reading here that many don't believe that the author main argument is right, which is: sustainable transportation for the future needs to be, mostly, public. I don't mean public as necessarily "provided by gov/city", but in which the common routes are handled by busses or trams or similar systems where, unlike cars, the weight of the moved people is not minimal compared to the weight of the moved vehicle.

Taxies have their place of course, you can't serve everything via public transports. Also one thing is normal people moving inside SF, another thing is arriving at the SF airport with a business meeting 45 minutes later. But the bulk of how people move, should be, mass-transport systems.
Public transport?! European Communist!
Take a look in other cities around the world. It works pretty well also for the kids, the elderly. Especially the elder, when they have problems using the car, because of their slow reaction times and bad sight. Especially, for the kids, as they are to young to drive a car.

I see here in Germany every day people (of every age), which can do their shopping with public transport. I've done it also in the past. Currently, my car is waiting in the garage 6 out of 7 day a week. I just use it sometimes, because its there. I can't use my car downtown anyway, because finding a parking spot is like playing a lottery and is expansive. It is more easy and cheaper to use public transport, or my bike, or my legs.

The only reason you are arguing this way is: you love your car. I've done that my self in the past. But I changed, and you can it too.
Users sent bitcoins to SR to hold for them, in return for a promise to return them on demand. So SR's assets and liabilities both increased with each deposit. Then USG seized SR's assets (under what right? That SR was an illegal enterprise established to facilitate narcotics sales). SR still has liabilities to its users, but now it can't meet them. Note that SR's liabilities are no concern of USG.

Come on guys, is it so hard to understand that if you exchange an asset for a security, you don't own the asset anymore?
that's right. But in Madrid families also use buses and trains to go to the center because it's faster and more convenient than car+parking. In Tokyo too. It's just a matter of investing in public transportation, and wanting a cleaner city.
> You may have to leave your home 10 min earlier, or arrive your home 20 min later; but it's a small price to pay to build the city we want to live in.

Given that most people will not take a job that is further than 30 min away[0], that actually makes a big difference

Wow, what an ignorant comment. Yes, I say ignorant because it ignores the reality of places where people do all the described things using public transport. These places actually exist. In many places in Europe, public transport is not only good, but faster and more convenient than private cars.

I live in Vienna, Austria where elderly and families with many children use public transport and carry whatever they need to carry. Bus and tram stations are not miles away, they are 150m away, and came at 3-10minutes intervals In the metros you can even carry large items easily, like bikes, for free.

Also in Europe we have supermarkets at every block, we don't have to do our groceries miles away.
Also the standards are not really open. Where can I submit a pull request?

I don't want to start a east coast vs. west coast feud over how rich boys spend their money, but there's a difference.
I can spot an east coast transplant, even after they lose
the accent--and they think, and spend their money differently too. There are always exceptions, but in my world East coast men are more competitive, less empathetic, and have taken more money out of my pocket than west coast men. Yes--I'm stereotyping, but in my world I try to avoid doing business with people who grew up in highly populated areas of the east coast. It's harder to make money on the east coast. I couldn't imagine trying to compete in New York.
I'll get beat up over this post, "down voted", whatever--I've just noticed real differences in people between the
two coasts. I'm tired of being so polite--oops I did it again.

> Let's be serious, people are paying $12-25 for taking a Uber or Lyft when they could be paying just $2.25. Does it take longer? Yes. So much longer that you willing to pay 4-11x? I don't think so. People are wasting money.

Disclaimer: I don't live in SF.

Yes, a million times yes it is worth it. The bus system where is I am from is far worse than SF but still, google map from location A to B and toggle between car and bus options. I can get there in less than 15min by car but unless I time it perfectly (and the bus is on time) it will take over an hour to get there by public transit.

Not to mention there are times when the busses do not run where I live. The author seems to think it's: busses or lyft/uber (and again that might be the case in SF) but where I am from your options after 11pm is taxis or lyft and I will easily pay more (though the rides so far have been nearly the exact same as the taxis I've taken) for a ride that I know is coming, I don't have to give turn by turn directions to, and I can pay by CC (completely impossible with taxis in my town).

So the author's argument of "Lyft/Uber sucks because busses" seems quite BS to me...
I only agree in case of disabled people, but if you live in a modern city with good PT (so not in the US ;), you have no need for a car.

Young children? They can use PT. It's a normal thing to do in my city (Austria). What about grocery shop? I mean, surely you have groceries around you so you can just ... walk there? go there by bike?

People who can not think of a no-car life just have never enjoyed good public transport.
You mean like GPLv3 does? GPL is hardly the be-all and end-all of freedoms, its just trades some freedoms for others.
I agree the parents tone was pretty bad but I agree with him to an extent. Most elderly people are fitter than you'd realise. I think the grand parent comment was wrong to stereotype them all as unable to walk 1 mile. e.g. surely an elderly person going to the mall to walk around shops can walk 1 mile to a bus stop?
The title is a blaming statement, which are usually caused by someone in cognitive dissonance. You can think of cognitive dissonance as an argument between various agents in someone's brain. Arguing with yourself isn't fun. Occasionally bits of the brain attempt to resolve the argument by looping in other people's feelings. The fastest way to do this is for someone to accuse another of something they themselves feel partially guilty about. which then (hopefully) elicits a strong emotional response.

There's ALWAYS a reason someone make blaming statements. The trick is figuring out exactly why they are doing it.

The problem with the title is much bigger than simply being inflammatory. The title makes a claim that is never established in the text. Nowhere in the text does the author make the case that people in SF engage in an activity that they criticize others for engaging in and/or engage in an activity that is counter to the espoused moral code of SF citizens.

The "classic 'white rich man'" sentence is truly bizarre.

Hey, I just read the post. I noticed that the share icon which appears on the left is actually the IOS/OSX one.
>> "Think of it in terms of resource utilization. In the old model, there's tons cars that need to be parked somewhere within SF while completely unused. In the Uber/Lyft model, these cars usually enter the city while they're actively transporting people, then they go back to the suburbs when they need to be parked."

Didn't we already solve this problem with taxis more than 50 years ago? It was already a 'sharing economy'. Uber/Lyft just made it more convenient.

> my small city has school buses for kids who live far from schools

Lovely word there "far". And what about the 4 year old who lives not "far"? Is he going to walk to school by himself?

And what about when it's not school? Or are young kids expected to never go anywhere?

> and minibus service that will pick up and drop off the elderly from doorstep.

Yah, I've seen those in a few cities, and you have to wait hours for your ride.

> But it can servve most people's needs

Only in extremely large cities (where you have enough people for constant 24/7 service), in smaller cities there is just not enough demand so you run fewer buses and it no longer works for most people.

> Deliveries

That only works if you know what you want, but not if you are comparing prices, looking for specials, what's fresh etc.

> cheap neigbourhood car rental or co-owning

You mean like the car service the author is ranting about?

> bike trailer

And there you go, you too can't seem to imagine the entire world is not like you.

Someone with a large family is going to take some of them with them when they go shopping. So you expect to have 4 kids under 6, plus a car load of groceries, on a bike trailer?
I thought the argument was going to be something like "SF supports restrictive practices in house building and rents, and therefore you should support restrictive practices in taxi service". Instead, it was even more dumb than that argument.

> The Internet; The Web; Firefox, WebKit; GNU/Linux, Unix; HTTP; SSH, SSL, AES; Python, Ruby, C, C++.

The internet came from the ultimate monopoly: the government. It was a government project developed by government contractors. Unix and C were invented at Bell Labs when AT&T was a government sanctioned monopoly. AES was developed while the authors were at an university research lab. Stroustrup started C++ in his PhD work, and did much of its early development at Bell Labs pre-breakup. HTTP and WWW were developed at CERN, a government research lab, as was the first webserver.

Its odd to use Python and Ruby as examples of the bazaar. They were developed by Matz and GVR, tackling the fundamental design decisions, before they were released to the community.

Development doesn't mean innovation, though its important too. There is innovation in open source, sure, but making another OO scripting language isn't as innovative as inventing Smalltalk in the first place (which was done at PARC when Xerox had 100% of the US copier market thanks to its patents).
> ignores the reality of places where people do

Only in the largest cities. And it's the same in the US.

But now look at the medium sized cities in Europe.

> Vienna, Austria

By the standards of the US Vienna is incredibly dense. There are only about 15 US cites that have similar population density.

Plus it's huge - over a million people. In NY the public transport is also that good. But there are only 10 cities that large in the US.
"""Conventional wisdom: Don't write cryptographic code!

Honest question here: suppose I have a webapp with multiple servers, being load-balanced through Amazon's ELB. This sounds about as standard as it can get. Question is: how does one handle client migration between servers, and client authentication, without writing cryptographic code or knowing anything about cryptography?

> I suggest you travel and see how other families/people live with public transport as their only transportation option.

I have actually.

And it works perfectly in huge cities, and it doesn't work in the smaller ones.

> The transportation problem in the US is city/urban planning, and not one solved by building more roads and putting more cars on them.

No, the transportation problem in the US is that it is very large, and the majority of the cities are medium/small and public transport simply doesn't work in those sized cities (just not enough demand for continuous service).
Just look at SF, in Chinatown the buses at packed with the elderly and their pushcarts full of groceries.

You're assuming that not getting to your destination on time is an option when taking public transportation around and especially in SF. At any point a MUNI bus/train can stop for extended periods of time with no explanation. Other times, there is an explanation like agents checking tickets and other idiocies. Either way, there's a great chance you're not making that 9am meeting with the VCs to secure funding.
We love cars simply because of the fact we could fit all of Europe INSIDE the US and still have room left over for Japan, the Philippines and a few other Asian countries.

It's about the only way to get around if you are traveling from one state to another - which we frequently do. Also, ~330M people.
"I'm sure you would think that the solution would be a really good public transportation with buses and trains. I'm completely sure private cars or taxies would be discarted."

This is something I always wondered, WHY? Have you calculated the numbers yourself? I don't believe so.

In Europe most people repeat this phrase, without knowing why, or just looking at the numbers.

I was born in Madrid, It looks to me like government propaganda too. You find ads on TV that tells you something like "a bus could carry 50 people, if everybody used buses we will be saving that much".

But most of the assumptions are wrong, E.g Most of the time the buses or subway are less than half empty.

And when they are full, people don't want to use the services. In Madrid, subway trains are designed for 4people per square meter!!!

Politicians want people to use public services(while not a single of them uses them). They want to raise taxes, people not being able to buy private cars, but giving the money to politicians in order to make big public works(and enrich themselves by the way, the bigger the amount of money they handle, the easier it is).

On the other hand, moving 2 tons for every 0.1 tons person does not make sense. We need individual alternatives like electric motorbikes or something.
In Europe 'cities are medium/small' and public transport works. Ignoring how cities evolve, grow, develop, from a planning perspective is the US biggest problem, and the solution its biggest challenge. Bad city planning affects transportation, energy, health, efficiency, etc.
What's medium sized? In Austria nearly all cities are connected to good PT, it's not a big-city only feature, even ~500 inhabitants villages are connected to PT. Of course it is not perfect, but it's there and it works reasonable well.

I think the bypass approach is a commonly used technique when a failure in any component exits the routine ... but it's also common for each of the failures to be processed differently, which actually looks like the fan-out that happens in a railway switching yard.

The author's primary example uses a "layout" I've never seen on a railway (http://fsharpforfunandprofit.com/assets/img/Recipe_RailwaySw...). Railway switches are expensive, so you never see multiple switches going the same direction between a pair of tracks. If there are two consecutive switches (and going say from left to right), one shunts from track A to track B and the other shunts from track B to track A. When space is limited, a cross-over might be used by these are even more expensive (an provide additional gaps where derailments can happen).
