venantius··on The MBA Myth and the Cult of the CEO
I don't find changes to share price to be the most convincing indicators of performance, though I agree you'd probably be hard pressed to find a better "generalizable" statistic. Fundamentally, I think measuring talent is an astonishingly hard problem.
venantius··on Travis CI Is Laying Off Senior Engineer Staff
Honestly I'm astonished at the speed with which this happened, given the recency of their acquisition. Seems amazingly cynical of their new parent company.
venantius··on Visa, Mastercard mull increasing fees for processing transactions: WSJ
Far fewer to almost none, BUT by the same token interchange rates on bank/debit cards are way lower than they are on credit cards.
venantius··on Visa, Mastercard mull increasing fees for processing transactions: WSJ
I mean the actual reason these companies are able to levy these taxes is because they provide contractual consumer protection. If we had strong consumer protection laws in the US in the first place, there wouldn't be much value left in Visa/MC etc.
venantius··on Ask HN: Have you paid for the photos/headshots you use in professional setting?
Yes - the guy who did our wedding photos was great and I was just starting my own startup and knew I wanted headshots. I was happy to pay him for an hour of taking photos and knew I'd get something usable out of it.
venantius··on Oracle allegedly underpaid $400M in wages to underrepresented employees
This is an amazing way to run a company. I love it.
venantius··on Ahead of IPO, Airbnb achieves profitability for second year in a row
It’s not nothing, but the difference is at least an order of magnitude.

Consider: I am probably 0% likely to book an Airbnb in my own city. Almost all of my Airbnb’s will be somewhere else, so I only really care about remote stock.

By contrast, something like 90%+ of my Uber rides are going to be local. In many of the places I might travel to, I don’t need Uber at all (the location is rural/suburban, the public transit system is cheap and effective, cabs are widely available, etc).

venantius··on Brexit Deal Fails in Parliament
I'm not sure I agree that a no-deal Brexit is such a good idea - given the (now exposed) lies of the Leave campaign, a second referendum seeems pretty reasonable.

At any rate - the idea that there is an alternative deal that someone can deliver on persists even now, which is insane. My favorite quote on this came from Michael Gove:

> “It’s a bit like a load of people in their mid-fifties at a swingers’ party holding out for Scarlett Johansson to arrive,” Mr Gove said.

> Amber Rudd, work and pensions secretary, added: “Or Pierce Brosnan.”

> Meanwhile David Gauke, justice secretary, claimed Labour’s Brexit policy was so fanciful it was “like hoping Scarlett Johansson is going to turn up on a unicorn”.

venantius··on Ahead of IPO, Airbnb achieves profitability for second year in a row
The main thing is that Airbnb has a global economy of scale - having more hosts in Japan actually does benefit their guests who reside in New York year-round. Competitors to Airbnb similarly must achieve global scale in order to compete in a serious way. There are one or two meaningful exceptions (China, possibly the US domestic market), but essentially any Airbnb competitor must achieve global scale in order to be a serious threat.

By contrast, Uber has to fight to win each city, and most of its users will use Uber for the most part within that city. Adding more drivers to Tokyo does not have a meaningful impact on the resident of New York.

venantius··on Airbnb Is Moving Faster at Scale with GraphQL and Apollo
This is the correct answer. When you search for listings in Airbnb what comes back is heavily personalized.

Of course, that only accounts for one of the various pages you'll see in the checkout flow, and I agree that not everything is as snappy as it could be. But keeping things snappy turns out to be a very hard problem when you're growing as quickly as Airbnb has.

venantius··on Airbnb Is Moving Faster at Scale with GraphQL and Apollo
I used to work at Airbnb.

Airbnb does not, in fact, have a CTO who dictates the company tech governance and/or stack. They prefer to run things in a federated manner, with individual teams making the decisions that they feel are best for them. While they're encouraged/required to draw up design docs and have them reviewed by an architecture review group, the group's recommendations are non-binding.

This model has advantages and disadvantages. On the upside, it creates an environment where people can take risks and do things that haven't been done inside of the company before. On the other hand, it means people sometimes go out on a limb and push the company into supporting something that turns out not to be sustainable in the long term.

As a matter of personal preference, I like to have a set toolchain that a company is built around. But it would be unwise to suggest that Airbnb's strategy hasn't worked out pretty well for them overall.

venantius··on You Weren't Meant to Have a Boss (2008)
> Implicit in my previous comment is that, because it's harder making things move in Big Corp one tends to learn more, both as an engineer and as a human. Finding the right technical path through a heavily used, critical system is an interesting challenge, and evolving legacy systems, or spawning new work in a large org requires lots of communication, as well.

Unfortunately the peril one often encounters in such ecosystems is that "the right technical path" for working with BigCo's system is totally un-translateable to general working knowledge. By that I mean it often means having to work around specific constraints that have evolved and are specific to that BigCo and not to other BigCo's, let alone to smaller startups. It also pushes you to generally work with technology which may be a bit older, which can often mean having to accept that current best practices simply aren't at play.

I do agree with the second part of your thesis, which is that the social challenges of working in a big company are significant and can make one very well suited generally for management and leadership in a way that's not the case at a smaller company.

When can I buy travel insurance that covers “drones at the airport”?
venantius··on The Science Is Clear: Dirty Farm Water Is Making Us Sick
Probably more technically it's inside the water which is inside the plant.
venantius··on You should never spend $825K on a domain – but here’s why I’m glad I did
In the UK it is mostly referred to as "cover", which makes me suspect that's the case in most of Europe as well.
venantius··on Facebook Betrayed America
The bible? Uncle Tom's Cabin? Das Kapital? It's not that hard to find books that - by themselves - caused revolutions or major social change.
venantius··on Facebook Betrayed America
I know you mean this in jest, but for a good part of the last century this was absolutely true.
venantius··on Facebook Betrayed America
I think the relatively simple answer is that it turns out most people are far more subject to simple tribalism than we previously wanted to admit. Memes are incredibly powerful mind viruses and we (collectively) have done a really great job of weaponizing them over the past 30 years.

I don't think this is Facebook's "fault" in isolation since we see the same trend across most social networks, but I do think it suggests that social networks ought to be regulated, if for no other reason than that it's pretty clear that the default behaviors we're already seeing emerge en masse are not good for society or for us on an individual basis.

venantius··on Goldman Sachs Ensnarled in Vast 1MDB Fraud Scandal
Well of course they were. What exactly made anyone think they'd actually changed anything, other than time and a bit of marketing? What they were doing at the time of the financial crisis was illegal then, and this is illegal now.

It turns out when the financial incentive is big enough, people will commit crimes! Especially when they're in an institution that seems to prize making money and "being clever" above following the law.

venantius··on Ask HN: Who is hiring? (November 2018)
Griffin | Full-stack or Backend Engineer | Full-Time | REMOTE | London, UK | https://griffin.sh

We're rapidly moving towards a world in which people get most of their financial services from non-bank fintechs than they do from banks. The problem is, most of those companies need to partner with a bank to actually hold their cash. We're building a purpose-built bank to do exactly that - power the global fintech revolution.

We're applying for full regulatory permissions and building a brand new platform bank, launching in the UK first. We've been working on this quietly for about 18 months and are now looking to hire our first engineer.

Tech stack: Clojure / Postgres / Kafka / AWS / Kubernetes

venantius··on The State of Agile Software in 2018
This article really hit home for me living in London. Having spent 7 years working in San Francisco and the valley, the degree to which "project management" and the use of buzzwords in the greater London tech scene are divorced from their original uses drives me absolutely bananas. And what's worse is that faux-agile has taken such a strong hold that I seem like the crazy person when I tell them that's not how software is developed in California.
venantius··on Who Are My Investors?
As a soon-to-be-regulated financial institution in the UK, we have to be careful who our investors are (and that includes getting into who the LPs our in our investors' funds). It's very easy to take cash, but nobody wants to have that hard conversation with the regulators 6-12 months down the line when they ask you to fully look up your cap table and you realize a quarter of your company is Russian oligarch money / from the middle east / from questionable shell corporations / etc. As regulators around the world get more serious about money laundering, this will become an increasingly important question for venture-backed firms.
venantius··on YC Top Companies List
> Afaik, YC is the only seed funder-startup accelerator in the world, among thousands of other ones, that has given birth to companies worth $1 billion ore more.

Seedcamp (London) has backed 3 unicorns: Revolut [$1.7B], UiPath [$3B], and TransferWise [$1.6B], and that's just a venture firm I know off the top of my head. While these days they're closer to a first-round fund (with a similar economic deal to YC) than an accelerator, most of those were from back when they were operating in a proper accelerator model.

I suspect there are probably a few other accelerators around the world that have unicorns in their portfolio - you just don't hear about them because they're not local.

venantius··on Ask HN: What's your favorite elegant/beautiful algorithm?
Surprised nobody's mentioned Hyper Log Log (or its more recent variants). A probabilistic constant-space unique cardinality estimator (i.e. if I see a billion events, how many are unique?) that also supports set operations.
venantius··on Why I Bid $700 for a Stolen PSN Account
I am going to refer to this thread, which shows exactly how easy it is and how difficult it is to defend yourself against: https://news.ycombinator.com/item?id=18194701
venantius··on Why I Bid $700 for a Stolen PSN Account
Someone tries to take over my Google account at least once a quarter. They haven't succeeded yet, but woof - it would really, really suck if they did.
venantius··on Why I Bid $700 for a Stolen PSN Account
Given the diligence with which the attacker worked on Sony via social engineering to gain access to the account, what on earth makes you think the same technique wouldn't work just as well for a telecom company? You don't need to "hack" the network, just the customer service rep. Just say you lost your phone :)
venantius··on Go 1.11 got me to stop ignoring Go
By authoring private structs with public constructors, you can get what you want out of this. Gets a bit messy with testing, but not impossible.
venantius··on What's a senior engineer's job?
One thing that I consider to be a really important part of a senior engineer's job that's not enumerated here is: helping more junior engineers come up with estimates for difficulty and time on projects they're about to undertake. To a senior engineer, there are a large number of projects that are fairly easily scope-able, e.g. "add a new API endpoint"; "refactor this medium-large model" that a junior engineer may not have the necessary degree of confidence to estimate. While this can sometimes be the responsibility of an engineering manager, not all EMs are sufficiently technical to know how long it'll take a _junior_ engineer to take on an otherwise easily-scoped task.
venantius··on Steelmanning the NIMBYs
Better transit would go a long way, it's true. But for reasons we haven't really been able to diagnose, building new transit infrastructure -- any big infrastructure projects, really -- has become ludicrously expensive in the US. It's almost certainly still worth the investment, but the numbers are so eye-popping that it requires significant goverment subsidizing, which runs into political problems that are hard to get around in the current environment.
