Four issues with the article:

#1: I understand the desire to do comparison in the market and look at Stripe's multiple vs. others, but PayPal and Stripe are not equal in forward looking growth. To try and apply Stripe's valuation multiple to PayPal's earnings assumes that PayPal is in the same sort of growth stage, which it clearly isn't. And most likely, Braintree was not either when they sold. Why sell if you're eating everyone's lunch?

#2: While numbers from six months ago may have been circulated and Pando apparently has those numbers, a lot can change in that timeframe. Large deals can be closed, growth can accelerate or very important technology can mature that has the potential to upset the status quo in Stripe's favor. General analysis of the market and knowing the habits of several of Stripe's investors makes me think that a key factor that is not public is in play. I expect a deal that gives them far better profit margin.

#3: "Stripe is a transaction-based business with a clear model — and one not growing particularly rapidly if it took two years to get to just $1.5 billion in annual payments volume our sources report as of six months ago." This is a bad assumption to make. As a rule, I never assume a company has a transparent business model as there are many aspects of technology and deal structure outsiders are not privy to. Who is to say Stripe doesn't have a new payments product on the way? Would it be so crazy for them to start snapping up downstream fulfillment companies with an $80mm war chest to maximize profit margin? Maybe so as they of course don't want to compete with customers, but who knows?

#4: Another issue with the assumption about payment volume is a linear growth curve. If you say "Braintree did $12bn in payment volume when it sold in late 2013, that means $2bn in volume growth per year, more than stripe with $500mm per year over 3 years of life". However, looking at articles that state Braintree's payment volume shows they were apparently doing only $3bn annually in 2011 at their $34mm Series-C (http://techcrunch.com/2011/06/29/accel-puts-34-million-in-on...). If Stripe is assumed to be making a rapid growth stride to make this raise, then they likely have a similar (or stronger) growth curve than Braintree did at that point (https://twitter.com/paulg/status/403183731449413632/photo/1)

The problem I have with the article is that you're making a series of assumptions and treating them as fact, or at least as highly likely. This is difficult to make stick with a company that is deliberately opaque, as is their right to be.

* I am of course analyzing this from a very-outside perspective and my assumptions should be taken with a grain of salt. Or ten.
Which technologies do benefit from GPU rendering? Aren't Quartz calls rasterized on CPU?
What would I say? Just what I'd said; that searching for a "solution" that allows working 80 hour weeks + having a healthy family life is futile because, IMO, it doesn't exist.

At least when you have kids. I could see a spouse being okay with "5-10 years of hard work" for lots of freedom after that.

Hard to make that sacrifice with kids though, because after 5-10 years, they're basically not kids anymore.

Ironically, if the 5-10 years works out, and the kids have a guaranteed life of luxury because of it, they might be grateful.

But I don't think it usually works out that way.

(Note that I'm only focusing on the "80 hours/week" thing. If you can pull off "changing the world" (or at least your pocket book) on 40 hours/week, more power to you.)
Congrats on shipping!

I interpreted "bad" in his post to mean "technologically bad" not "morally bad". On second thought, I might have misinterpreted his post. In that case, then the obvious answer to "If LLVM is so (morally) bad why are the people who make it so much easier to work with?" is that niceness and political ideology are only very loosely correlated, at best.

The other part of my comment still stands, though (I think).
Where do people get these misguided notions about email? You don't need dkim or spf at all, few people check either, and they are just to prevent backscatter. Running your own mail server is trivially easy.
I didn't find postfix all that hard to set up. Courier, on the other hand, is a disaster area, which is why my mail server runs dovecot instead; the latter took little effort to configure, and works quite nicely across several devices. The really hard part was finding a halfway decent CalDAV/CardDAV server that didn't require undue suffering to configure; I settled on Baïkal, which works okay, but could be considerably improved upon.

You are correct in that the license is free, but it isn't a copyleft license.

This is a purely political decision: RMS wants gcc not only to be free software but he also wants it to be unusable to create non-free derivatives thus making it an active tool in furthering free software. clang undermines this because you can create non-free software based on it thus making it a tool that can easily be used to restrict freedom.

> The short answer is: I work on side-projects whenever I have a spare moment. I sacrifice other things (watching TV, reading the newspaper, playing video games) so that I can do creative work.

I tried this approach for a while, but it greatly degraded my quality of life. Eventually I found that I was always hunting and hoping for a spare moment, instead of just enjoying whatever moment I was already in. It's true that I get less side project stuff done now, but I'm happier, so that's what counts for me.
Yeah, the MySQL 5.6 defaults are quite different to the ones mentioned here. Also:

- the query cache is now off by default (but 1M)

- innodb_additional_mem_pool_size no longer applies.

- some of the per-session variables can actually allocate more than once (or not at all).

- There is fixed memory allocated for performance_schema per thread.
Can you point to a trivially easy set of instructions please? ;-)
> Every comment you have posted defends Uber and not just on this issue but others as well

Every comment on this thread. This thread about Uber. So yeah, every comment's gonna be about Uber. And as a long-term commenter and bystander with no skin in the game, I don't have to have a game. But, as you've pointed out, you're a tech reporter, so you presumably are angling for something, probably some story hook. In any case, I'm defending Uber because I think a lot of things are being said that are not fair or accurate. You'll note that I have not tried to defend the actual practice of harvesting phone numbers from Gett. I think that's pretty bad, as well as whatever the Boston office is doing with their cute names. But people in this thread are rather intent on talking about other things, such as the new years eve accident (wherein Uber behaved acceptably as far as I can tell).

As for company culture, the cute names were from the Boston office. pain_perdu did not say these names are used across the entire company. It's certainly possible, but from that one anecdote all I can say is that some people (heck, maybe even just the one person that pain_perdu knows) uses these names. There's nothing to indicate there's a company-wide culture of this sort of thing.

Although, to be honest, given what I've read about the CEO of Uber, I wouldn't be terribly surprised if the names are used elsewhere. But I don't see why we need to excoriate Uber over an assumption that hasn't been verified. I prefer to assume the best and not the worst.

Depends on the commute - I bought a small laptop so I could work on my side project while on the train. I've found that I can get a lot done in the 10 20-minute legs of my weekly commute. I'm sure it is less efficient than taking the 200 minutes in a solid stretch - but it was easy to fit into my life so I kept with the habit (which is the hard part for me).

Not exactly. A more accurate comparison would be

And if one day docker gets a jails execution driver:

qmail was once a great piece of software. Then it stopped being maintained, and it lived in a licensing no-man's land for quite a while that effectively prevented new maintainers and viable forks from existing.

It's no longer current technology and fails to comply with RFC changes that have happened since it was released, including but not limited to 6522, which standardizes bounce messages.

It still does very well at the job it was originally designed to do, but it's no longer a modern, usable tool. It doesn't belong in the modern email toolbox any longer.
PCPro and Wired suggest otherwise.

Ask HN: Appointment Booking Software?
Hey all, can anyone recommend software for booking appointments on behalf of clients? Most of the systems I'm coming across seem clunky or short on features. I'm looking for:

- Calendar invite
- Allow multiple staff/clients to individually set their own availability, and integrate with their own calendars
- Easy to use

Any recommendations?

Many thanks.
Perl has always been in the bundle - at least as long as I've been using it. I used to use it as an easy way to get a Perl installation on windows that didn't need to use the registry.

I remember one of the Apache Friends guys helping me by specifically creating a bash script to trim down the distribution to fit on a 100Mb zip disk (probably back in the early 2000s) so that I could have a portable web dev environment that I could use on the computers at my University.

I've always had fond memories of ApacheFriends since that time.
It works largely, as long as you are careful to recognize when too much is too much and your brain needs rest. Take care of not burning out (I'm a father with 2 kids who use that technique fairly often - it definitely has limits).
Sometimes commutes are unavoidable, but I've found that podcasts and audiobooks make this time feel less wasted and helps regain the time taken away from personal entertainment time when working on side-projects.

Buy a domain on a service that allows API-based DNS updates.

Put up a RPI at home. postfix + dovecot + roundcube should do the trick.

Add FW forwardings for 80/443/25 (or allow IPv6 to pass through)

Update DNS records every N minutes. (cron, nsupdate, dyndns clients, amazon command line tools....). You will need SPF/DKIM.

The RFC for SMTP says Mail Servers have to retry for 7 days before giving up on mail delivery. This should be plenty for your home server. There are also commercial Mail relay and backup MX services (sometimes even as a free offer for buying domains on website X).

You can backup the SD-Card whenever you want. Your Mail stays at locations you control.

I currently have a root server, but I'm heavily considering "in-housing" those services because of the NSA activities.

EDIT: it's 7 days
PS: Some old firewalls block dynamic IPs for mail delivery. I'm not sure how common this is today, especially as SPAM and botnets have evolved a lot.
I've run my own mail server for many years, and delivery problems are very, very rare.

DKIM & SPF are marginally useful (at best) for ensuring delivery. You're much better off registering your server with http://www.dnswl.org/

Reasonably smart kids can understand a lot of things if one takes the time to explain it to them a bit, along with the reasons why a particular thing is the way it is.

I'd suggest you try to avoid dumbing things down too much, just because he's a kid. You might be surprised.

German healthcare is clearly superior by any measure not thought up by a Koch-Brothers think-tank. It covers 100% of treatment, and even if it didn't, list prices for treatment are not off-the-wall absurd. I'm not arguing that the ACA fixed US health care, nor would I.

My point was that the cost of living here is also very high. Sure, there are EU/US trade-offs all over the place, but they are not anywhere near big enough for you (or the GP, or anyone) to just wave away a factor-of-three pay difference.

Btw, yes, last I checked my monthly premium is over 400€, so it cleanly weighs in within the range you name. I switched to private insurance because public 'Krankenkasse' charges a percentage of gross income, which would turn out to be even more. Not complaining, just answering your question in case you really wanted to know.

The license is bad, not the software.

> If LLVM is so bad why are the people who make it so much easier to work with?

How is the license being bad influenced by, or of influence on, the attitude of the developers? Are you saying that surely the license can't be that bad, since the software is written by nice folks?

Ask HN: Friendly Cities?
HN seems like a community where people get around quite a bit. I'm looking for opinions on friendly cities. First a few points to try to frame what I'm asking:

1. I'm not looking for "people are people". I've lived in Boston and Seattle, and in my opinion you'd have to be completely 'deaf' not to feel the difference. My question both assumes, and insists, that people act differently in different locales.

2. Same for "people respond to you, so it's all you, man". That's deep, but for the love of straightforwardness, I implore you to save those keystrokes. Again, if you think it's all the same, I'm emphatically not addressing the question to you.

3. It would be great to hear from people who have lived in at least 2 cities / places.

4. If you're going to recommend someplace outside the US, hopefully it's somewhere an english-speaking US citizen could reasonably get a work visa. That said, there's no reason for me to hog this thread all for myself, so post away.

Thanks!
Go to work for an ISP. My mail server doesn't cost me anything. =)

Interesting project, but I'm a little disappointed it's not a shiny new thing for the bhyve virtualization layer[1] introduced in freebsd-10, but rather builds on "plain" jails.

I did get multipool and middlecoin mixed up. My mistake. I was mining doge directly for a while but I quit to mine litecoin two weeks ago or so because that was much more profitable. I was actually making much more money mining litecoin rather than dogecoin. That might have changed because I heard the exchange rate went up a couple days ago. After mining litecoin for a week and having the best luck with that I moved back to a profit switching pool, hashcows, to see if they will be more profitable, even though they had a sql injection attack lately. I wanted to see which was going to do the best for me. I haven't even been home to change my miners even if doge is more profitable right now and I have to go on travel. So far litecoin and hashcows are about the same in profitability for me as of lately.

> Deliberately waiting until the last minute to cancel a ride would certainly indicate intent to disrupt.

Sure, if they actually did that. At the moment this just seems to be Gett's word against Uber's, and since doing that would not in any way aid Uber's goal of harvesting phone numbers, I'm not inclined to believe Gett just on their word. The most benign explanation is that the drivers simply didn't check their phone to see that it was cancelled until they'd arrived at the address.
This is like asking my employer to pay me in GBP instead of USD because their notes are prettier.
use Virtualmin (http://www.virtualmin.com/), it will configure postfix/smtp, dovecot/imap, dns & web hosting.

Its abit like cPanel & Plesk, but you don't need to use the control panel if you know what you are doing.
Can Gett actually prove there were any damages at all? Not only was Uber paying cancellation fees, but unless Gett can prove that this caused at least one "real" Gett customer to not be able to book a ride, then it's hard to say that there actually were damages.
