jnks··on Porting my Score4 game to React/TypeScript
For those struggling to beat the AI, Connect Four is a solved game [1] and whoever goes first can force a win by starting in the middle column.

jnks··on With regards to Apple Music
What's happening here is not a shift to net 90, and it's also not an attempt by Apple to rip any rightsholders off.

Instead, it appears Apple and the major labels believe that three free months of Apple Music threatens to hurt Spotify's userbase growth at a crucial time for Spotify (fundraising pre-IPO). The industry has lost its faith in freemium (Apple Music, trial aside, has no free tier) and either this will kill Spotify or get them in line.

The indies, who overall can't afford losing three months of revenue, are just caught in the cross fire.

jnks··on Sony Terms with Spotify Uncovered in Contract
There's nothing in the contract between Sony and Spotify that's all that surprising. Even the large looking advance of $45M is only a small fraction of what Spotify would have paid Sony each year.

If anything, the "unfairness" of the contract terms is a reflection of the HUGE amount of leverage the record labels have because their content is so valuable. Is it evil for the labels to attempt to maximize their profit while minimizing Spotify's?

jnks··on It looks like Intel is developing Bitcoin mining chips
21 will surely dole out some of their 75% cut to hardware integration partners as a distribution fee. The ripoff here is for anyone ignorant enough to run one of these devices.
jnks··on Spotify as a simple case study in making something people want
RIAA.
jnks··on Harvard engineering students devise BBQ smoker
If you've ever wondered what the real value of going to Harvard is, it's all in this sentence from the article:

> On a hike up Camelback Mountain in Arizona, he pitched the idea to executives from Williams-Sonoma, who agreed to be the client for his class.

Just casually pitched an exec and got a brisket sponsor, no big deal...

jnks··on Spotify as a simple case study in making something people want
This may underrate the real difficulty of Spotify: convincing record labels to let them give away music for free on the assumption freemium would have a reasonable conversion rate to paid.
jnks··on Deprecating the Sync and Datastore APIs
Ironically, if developers like yourself had adopted the API, they wouldn't be deprecating it now.
jnks··on Silk Road trial closes
Roughly, "hearsay" means that the person testifying to a fact was not a witness to it themselves or does not have direct knowledge over it. So it's entirely possible that some parts of the affidavit are hearsay while others are acceptable testimony.
jnks··on Coinbase Raises $75M from DFJ Growth, USAA, NYSE, and More
More likely: a push to become the next PayPal, but using the Bitcoin network rather than the standard ACH banking network. Here's one step towards that: http://avc.com/2015/01/feature-friday-us-dollar-wallet/
jnks··on Robert Morris: All About Programming
My reading: Bell Labs folks would have ordered it Programming > Math >> Computer Science. RTM was good at programming, was being taught CS at college, and took too long to learn that neither that nor math were for him and that Bell Labs had it right all along.
jnks··on Uber’s Latest Experiment Is Uber Cargo, a Logistics Service in Hong Kong
For a certain definition of "success", yes definitely. Uber's sky-high valuation (and the accompanying deluge of investment dollars) hinges on their ability to address a market larger than US taxicabs. So press about them doing something other than driving around people in a market other than this one is worth a lot.

Are these experiments dollars-and-cents profitable? Almost certainly not.

jnks··on Box Moves Ahead With IPO
At the $13/share pricing, Box will be paying its previous investors back penalty shares. Apparently they promised a share price of $20. [1]

jnks··on Hollywood's toxic addiction to franchises
The fault for Hollywood's endless sequels, remakes, and remakes of the remake should probably be laid primarily at the feet of the American viewing public. We won't make the hike to the movies for artsy stuff like Birdman, but Spider-man I (Remake III)? Already got my ticket!
jnks··on A system that pours a glass of wine without opening the bottle
Way more fun, at least.
jnks··on The United States needs to overhaul its law-enforcement system
> I don't think it's as simple as "if someone dies there needs to be a trial".

But there almost always is in reality, if there's a reasonable suspect. The only exception seems to be with law enforcement officers.

jnks··on The Byzantine Generals Problem (1982) [pdf]
Perhaps because there's a lot of breathless press [1] about Bitcoin solving this "impossible" problem that was in actually solved decades ago?

jnks··on Introducing Snapcash
Square loses something like 25 cents per Square Cash transaction [1], and now they want more transactions? I wonder if Snapchat is paying those fees, and if so how they think they're going to make that money back from their users.

jnks··on Avoiding Complexity with Go
The solution to number 2 (if it really needs one) is simple to use `if !ok` instead to push the exceptional case to the right.
jnks··on Sports fan lobbyist fights NFL blackouts, taxpayer-funded stadiums, and Comcast
I'm sure if hospital threw off hundreds of millions in entertainment and tourism revenue municipalities might be more amenable to funding them...
jnks··on For Billion-Dollar Companies, Venture Deals Outstrip Going Public
It appears there's only room for 11 or 12 big IPOs per year. If the current trend holds and late-stage investors are creating more private unicorns than the public can bear, we have a problem. The fallout from this mismatch wouldn't look like a tanking stock market. Just a lot of formerly impressive companies quietly being acquired for a relative firesale. I suspect Box and Square are both in this situation.
jnks··on Houston City Council gives green light to Uber, Lyft
If you think about it for a second, it's only really possible to do this for one direction of traffic at a time on a given multi-block street segment.
jnks··on Show HN: QuoDB – Movie quote search engine based on subtitles
I'm partial to "We've got company!"

http://www.quodb.com/#search/we've%20got%20company

Incoming is the moral equivalent (and is much more popular), but is less impressive since it's only one word.

jnks··on The Happy Demise of the 10X Engineer
The software equivalent to doing your own plumbing has been here since the mid-90s: build your homepage with Geocities.
jnks··on Confessions of a startup: all our numbers, insights, everything
Gotta love those cumulative graphs. Linear growth? Now it looks quadratic!
jnks··on Go Hercule
The idea is it's `for k := range object` to iterate over the keys, and `for k, v := range object` to iterate over the keys and values, whether the object is a slice, array, map or string. The only exceptional case is a channel, which has no indices/keys.
jnks··on Beautiful illusions: the economics of uberX
You're arguing strawman points the article doesn't make. The primary claims I see are

1. Uber drivers don't make as much as Uber PR claims (based on data Uber provided).

2. Uber the business doesn't seem to be wildly profitable, or at least not in a defendable way (based partly on data Uber provided).

3. The large amount of capital being injected into Uber are not indicators of growing real value, but instead indicators of a weaker-than-acknowledged business.

It's possible for all of the above to be true but for drivers and riders to both be very happy with the service. Especially since UberX seems to be offering rides for below market prices but the drivers are getting switching bonuses and per-hour guarantees (see elsewhere in this thread).

jnks··on Show HN: A fast ISO8601 date-time parser for Python
How many dates are you parsing at a time that optimizing this would make a noticeable difference to users?
jnks··on Is Go an Object-Oriented Language?
The author of this blog post is a little confused about embedded structs. His examples of has-a and is-a are both has-a's, and the syntax change involved (leaving off a name for the embedded type) doesn't actually do anything.

  type Person struct {
     Name string
     Address Address
  }
is equivalent to

  type Person struct {
     Name string
     Address
  }
And in fact, these are equivalent too:

  p.Address.Zip = "01313"

  p.Zip = "01313"
http://play.golang.org/p/aKH3YxT5Mb

Go doesn't really support is-a for structs, as pointed out elsewhere in the comments here. Interface implementation is the only way to get the sort of "this type can be substituted for this other type" idea that is-a inheritance provides in other languages.

jnks··on 4 Years In – Uber raises 1.2B at 17B valuation
Technically they're raising at $18.2B or $18.4B in the typical sense of the word "valuation" since the 17 is pre-money.

Also, as an investor in such a late round, there are likely multiple provisions for getting your money back such that while a large investment, it may not be particularly risky. Even if Uber crashes and burns and gets acquired for only $3B, investors in this round probably still double their money.
