If you mean that getting accepted to YC doesn't guarantee that your business will be successful long-term, then I agree completely. Getting into YC is definitely a signal that it will be successful, however. That's why you have a higher chance of getting VC funding.

> Entrepreneurs you shouldn't let getting rejected from Y combinator or any other accelerator bother you. You should consider the feedback they give and try to validate it and if what they are saying is true, try to correct what is wrong.

There's nothing wrong with letting rejection bother you. It's what you do after you get rejected that matters. I think your suggestion to consider any feedback you get, and adjust what you're doing based on that feedback is awesome advice.

> Consider one other point, while Y combinator partners are successful they are really not that successful. They haven't achieved as much as Elon Musk, Bill Gates, Mark Zuckerberg, Larry Page,Jack Ma etc. If Y combinator partners were really successful they would be running multi billion dollar companies, but they are using their skills to filter out applicants to Y combinator. So don't take their rejection as the law.

As we saw in YogaTrail's rejection letter, even YC knows that their rejection isn't the law - "we are often wrong in our decisions". On the other hand, while the YC partners may not be as "successful" as Elon Musk and Bill Gates, YC is a billion dollar company[1]. So, the YC partners are technically running a billion dollar company.

Blossom CEO gives advice on how to manage distributed team
It looks to me like it has a bug - it doesn't seem correctly to factorize anything with a square factor. It also only need to loop up to sqrt(x), not x, but that's an efficiency issue. It also doesn't correctly use an early abort when x has had factors divided out.

There are more problems. Personally, I'd worry more about them than the indentation, but if code layout is your biggest problem, go for it.
Plus a SatNav won't know that at rush hour, a longer (distance-wise) route could be quicker in a black cab due to them being allowed to use bus lanes.
How Nintendo can save itself
That's cool, but you could also build an MVP using PHP and MySQL on cheap shared hosting or a cheap $5/month Digital Ocean instance. Unless you are on the Microsoft stack, you probably aren't saving a ton of money that you couldn't save by making different decisions.

Probably the more valuable opportunity in BizSpark would be to get any extra marketing out of the relationship with Microsoft. Being a "success story" can get you press, links, etc. which is very much more valuable than saving money on hosting.
Uber gives 80% of the fair to the divers. I'm struggling to see how it could earn profits "far in excess" of of that 80% unless it invests whatever is left of the 20% after overhead in some really lucrative City investments.
I subjectively don't find those philosophies interesting, and have a distaste for assigning single ideas to heterogeneous groups like "the west". Your mileage may vary.

For example, I would consider myself western but I don't have any problem imagining systems with true, false, both and neither. You just treat them as anonymous values with particular operations, instead of getting stuck on "but if we were in this other system that we're not in, this would violate an axiom!".

(If I thought this was a flaw in the article, instead of my opinion of it, I would have just said it was terrible instead of saying I didn't enjoy it. Its style just grates me sometimes.)
I had a neighbour that was doing the knowledge. We used to hear him practise in the back garden with his wife. Hearing her shout random routes at him like "Buckingham Palace to Bank Tube" and him spouting one road name after another was pretty amazing.

If you're ever in London and you see a guy (or girl) on a bashed up moped with a clipboard strapped to the handlebars, they are learning their routes for The Knowledge.
Yes, I do know their side of the story, and I'm sorry to say that I still have the opinion written above. The Black Taxis are rather obsolete. As a consumer I don't really care that they learned The Knowledge since it won't help routing me around a traffic jam that just started a few minutes ago, to give one example!
I didn't even see that at first, although now that I look at it...
I kind of like the term "block box". It takes a black box, and defines it in terms of how it's used, not what it does. It is a block that can be implemented in a certain way. How does it work? Doesn't matter at this level. It's a building block for a differently-focused project. A block box.
I don't know - some modern satnav systems are able to get hold of live traffic info and suchlike. That was always the point of The Knowledge - to know (for example) which major thoroughfares to avoid so you aren't going to be sitting in gridlock for an hour, however counterintuitive such evasive manoeuvres might be to an automated route finder.

The better informed the satnav, the less valuable that is.
Yeah I agree. Living in a not so dense city, I knew that I wasn't going to find any matches with just a mile radius.
I've used Climate Cars a few times and they're great. Mostly on time, their drivers are courteous and well-dressed, and they have a fleet of nice cars (I've mainly been in Prius and hybrid E-class cars).

Every time I get in a black cab, I wish I had booked with them. Most mini-cab firms are atrocious - staff are rude and they have no idea where they're going.

There's already good competition, but if there's more coming then I'm all for it. Black cabs have a bad reputation.

(Edit: no, I don't work for them or have any affiliation.)

"This taxi driver could be a criminal and/or scam you in the fare" might resonate with people.

It might also tap into latent racism about immigrants driving around with the same level of licencing.

jaxytee: fyi, you are shadowbanned; there's no contact info on your profile, and your previous comments suggest no reason for the shadowbanning.
Sorry, I guess I should say I wasn't speaking with any experience of taxis in London. My statement mostly applies to things I've read/heard about taxis in the US and Canada.
Screw the black cabs.

I didn't realise what a rip off they are until I started driving around the city myself regularly with Google Maps which to be honest with traffic aware routing destroys "the knowledge" instantly. Black cab drivers know how to make cash, not the most efficient journeys in time and money. That meter hurts you badly.

So they'll cause some chaos; good for them but it'll raise more awareness on the issue and hang them faster.

More competition is required in this sector for the passengers.
Hangouts chat uses Jabber, Facebook Messenger uses XMPP. Skype uses a proprietary protocol, and licensing restrictions prohibit any unofficial client from connecting to the Microsoft severs. I don't know much about Viber or Whatsapp internals, but I would hazard that Viber is similar to Skype.

Chances are that you can connect with most people over Google or Facebook, but it's not perfect. If you are still using their servers, then it might defeat the purpose of avoiding their clients. You can use Off The Record (OTR) to avoid the privacy implications of using the servers with both of them, but none of the official clients support it, so they would have to use an alternative client as well, which defeats the purpose of using existing networks.
For the purpose of my and other people's safety, I don't want my taxi driver to be constantly looking at the phone at the busiest junctions, neither do I want to explain to them how to spell a given street name so that they can type it in their phone in the middle of a busy street during the rush hour.

Maybe in 2024.
Tips and Tricks for switching from Windows to Mac
They're probably talking about the Google not having it's corporate offices in the UK. The UK is a massive tax haven anyway, with weird little sub-national groups like the Channel Islands and Isle of Mann.

edit: Yes I'm aware the Channel Islands & Isle of Mann aren't part of the UK, but they are 'British' and massive tax havens, sometimes with one company director per inhabitant.
Having taken a non black cab yesterday which involved the driver reprogramming the sat-nav, whilst talking on his Bluetooth and handing my friend a business card, I'm OK with relying on human knowledge once in a while.
Well, that's a simple software problem with street definitions. Much simpler to fix than what amounts to implementing a GPS/pathfinding system inside someone's head for even one driver.
You'd still be saving money, you can run PHP and MySQL on Azure and get enough server power to host your production app for free instead of paying a shared hosting company $5 for something only sufficient for development.
Could someone explain why Priest, in discussing the 'four corners', presents the Hasse diagram with {F} at the bottom? Why would it not be {}? I'm not too familiar with posets, but it seems the order matters, right?

Not sure if you really did this by accident, or if you're playing dumb, but the article does sound like claiming it'll make a phone NSA-safe. Yeah, now that you said so, I notice that it doesn't explicitly claim so, but first paragraphs are sure sprinkled with the name; if you really cared about the reader's safety, it would be responsible then to explicitly state that this advice does not protect against NSA.
Seems like Akamai stands to gain from an un-neutral net. They provide a possible way to minimize the effects of congestion.
Good engineering practice: you have an untried technology operating in a complicated environment and in-house testing can only get you so far. Looking at this "in the wild" in a constrained way where you control most of the variables is an obvious next step.
One of the key benefits of The Knowledge is that I can jump in a black cab in London and say "Royal College of Veterinary Surgeons" and have a driver who can instantly decide which way to go...

1. Without asking for any clarification

2. Without typing a bunch of stuff into a GPS device

3. And with knowledge of time/space specific optimizations

Yes, black cabs are not cheap. You are getting a very specific service for that money.
It's not "constantly looking at the phone", it's the plain old "using navigation in your car" that many people already do. AFAIK, safe driving with navigation is a long-solved problem.
This only seems useful if it is automated and extremely fast. If you are law enforcement there are faster ways to do this. Like just calling in the city the "bad" guy last checked in at.

And if you aren't, there are much easier ways to get info on the room someone is using, like social engineering. Which I'd actually one if the examples the author gave when he simply asked the victim in twitter what floor he/she was on.

I haven't seen criminal scenarios where the bad guy takes a photo if his view or checks in on four square, that doesn't get rounded up fairly quickly.
If you only want to go partway to catuskoti, consider the intuitionistic logic of Heyting and Brouwer. This is the actual form of logic which has the Curry-Howard isomorphism with lambda calculus. In particular, it rejects PEM but not PNC.

What does this world feel like? Well, let's assume we've formulated a proposition. In type theory syntax we'd write the body of the proposition `B` and give it a name `p` like so

p : B

Here p is just a symbolic name and B is some formal language expression which describes the proposition p.

It's important to note that while we've immediately written this proposition but we've not established whether it is true or false. PEM would imply that the state we are in currently is unstable—p must be either true or false already!

Intuititionistic Logic, however, admits that the state of almost all propositions is far closer to what p is now—neither proven nor refuted. This neither-true-nor-false state is natural and only through a process of communication and work can we move forward. For instance, we could construct a proof of p

p : B
p = proof1 -- note how this looks like a typed program now

or we could construct a proof of its refutation

notp : not B
notp = proof2

But we might be incapable of either. It is unclear whether a program searching through the space of possible proofs would ever terminate, one might note.

What's immediately nice about this system is that it can model internally the notion of an independent statement—all statements are assumed independent until proven otherwise even!

It also reflects the nature of (functional) programming (of a certain style) where we define the type we're hoping to achieve and then work to create a program satisfying that type.

Note finally that Intutionistic Logic still holds that PNC is true. In particular, we can trivially prove the following proposition

notPNC : forall prop . not (prop AND not prop)
notPNC = /\_ -> \(p, np) -> np p -- this is a legitimate proof term written in (System F) lambda calculus
In the absence of a pre-agreed/fixed price most minicab drivers will charge based on a combination of distance/time measured using the vehicles trip-meter/odometer and a clock. That's not much different to what the Uber app is doing in (surge multiplier excepted).
Neither the Channel Islands nor the Isle of Man are in the UK.
If downtime is a concern in any way, wouldn't you have at least two servers and thus the ability to do rolling reboots?
It's a reason not to make free services. Two million is a huge user base if they're all giving you $10/month.

Consumers are willing to pay for value received. I'd certainly pay for a good solution to the mess that is bookmarks, something to complement Pocket. Unfortunately del.icio.us was never quite there.
Tried it for me. No-one online now. Another idea: Chat-room with the nearest 100 people. Scales up and down.

>> TfL told the association last month that it believed Uber's vehicles were not strictly "equipped" with taximeters since there was not "some sort of connection between the device and the vehicle".

Instead there is a device used for calculating how far it has gone, e.g. "metering"... this is a bollocks distinction.

A multi-valued logic (at least of the sort described in the article) is not stronger than a single-valued one. They can be transformed into one another.

For instance lets say give the proposition "the sky is blue", the truth value (0.78, right here, right now), corresponding to being quite blue, but not necessarily always or everywhere.

truth value(the sky is blue) = (0.78, right here, right now)

Since a function is just a special case of a relation, we could say

the sky is blue ~ (0.78, right here, right now)

And a relation can be described as function from the composite space to {false, true}, where false denotes not related, and true denotes related. So we could transform the whole thing into

truth value((the sky is blue, (0.78, right here, right now)) ) = true

Now another question is which model is most convenient.
So I have to explicitly state what this article is not about. Interesting approach...

Licensing costs are not really an issue when you're on Azure. If your app ran fine under the BizSpark program subsidy of $150/month of azure credit then when you're out of the program you'd just have to pick up the $150/month hosting cost, not suddenly have to pay $15k+ for a MSSQL or Windows Server license.
Just like in any 3G USB dongle you attach to your PC (in fact, Neo900's modem operates in exactly the same way). For something as close to "free baseband" as possible, get a Neo Freerunner (or some other phone with TI Calypso) and install OsmocomBB - however, you won't be allowed to use it legally on public networks in most of jurisdictions in the world.

The word "performant" still grates on me.
It's been thrown away in some (growing) part of modern mathematics and has lead to the creation of automated provers as logic rejecting PEC and not PNC models lambda calculus. See my top level response in this thread for more detail.
> Any advances that Uber makes will benefit all mini-cab companies and most importantly, passengers.

Except for all of the disabled ones, the wheelchair users, the ones who only wish to travel a very short distance and are unable to do so alone (the pregnant, mothers with pushchairs, the extremely inebriated, elderly, injured, etc).

The monopoly and some privileges (bus lane access, pick up fares anywhere) is granted in exchange for a lot of obligations including accepting every fare in the centre of London even at a loss (of time spent against the profit of a fare), for fixed prices, and without excluding anyone of any ability.

If Uber wish to gain the advantages that black cabs have, then they are free to accept the responsibilities and obligations that come with it. Which will of course mean changing their whole fleet to fully accessible vehicles and not allowing any driver to refuse a fare.
Of course they do refuse fairs, and a couple of times I've heard the "I'm not going in that direction" reason.

Not sure why you're being downvoted, and I've no direct insight into Apple's deployment decisions.

But I'd guess they're concerned that deploying MPTCP could cause problems with middleboxes in some environments. Siri is a good way to test the water. First, they own the servers, so they can ensure there's no problem on their end. Second, Siri isn't mission-critical in the way IMAP or HTTP would be, so if there is a problem, it's less of a PR disaster for them.

Personally, I'd also prefer to see an API that developers can use to enable it, but I'm OK with them taking it slow at first. Every cellular and WiFi network on the planet got to see how their middleboxes handle MPTCP, so having them test the water like this makes life so much easier for anyone else later.
Does their story matter if they purposefully block the city traffic? Sure, it may matter on its own, but if they break the law and make life harder for others, that behaviour cannot be excused. They may have learned for the test, but in the time of satnavs that already have all the streets, digital broadcasts of current roadworks / street closures / accidents, and waze/google like collection of real-time data about traffic, that knowledge is simply not required.

Someone else is not keeping their service in line with the regulations and it costs them business? Sue them. Doesn't work? Well, the same rules don't apply to you apparently, so your life just got a bit easier.

I'm in favour of some regulation of the transport services. But as soon as companies try to backstab each other at the cost of people in the city - charge them for it, I'm sure there are other companies that will be happy to take over.

Intuitively, it is to indicate degree of 'truthiness'. Certainly false {F} is less truthy than either both true and false {T,F} and neither true nor false {}, which are in turn less truthy than certainly true {T}. The Hasse diagram indicates that there is no relationship between {} and {T,F} in terms of level of truthiness.

More mathematically, you can think of the Hasse diagram as a lattice, with the meet and join operations being AND and OR. For example, we are used to thinking of the expression

p AND q

as being true if p is true and q is true. But what if we have four values: {}, {T}, {F} and {T,F}? The Hasse diagram tells us how to interpret expression like this - p AND q is the meet (greatest lower bound) of p and q, and p OR q is the join (least upper bound) of p and q. So for example,

{F} AND {T} = {F}
{F} OR {T} = {T}

{F} AND {} = {F}
{F} AND {T,F} = {F}
{F} OR {} = { }
{F} OR {T,F} = {T,F}

{T} OR {T,F} = {T}
{T} OR {} = {T}

{ } OR {T,F} = {T} // I think..!
{ } AND {T,F} = {F}
{ } OR { } = { }
{ } AND { } = { }

The Hasse diagram in the article makes sure that expressions like this agree with our intuition in the cases where we have intuition for what the result should be, and give us a way to interpret expressions consistently when our intuitions fail us.

We're used to seeing Hasse diagrams for subsets of a set S used to indicate inclusion, in which case you would have {} < {F}, but you can have a valid poset structure that's not based on inclusion.
