cschneid··on Amazon Is Seeking $16B Bond Sale for Whole Foods
The answer probably is: "Capital could be better spent on the core businesses" rather than that they can't.

Even Amazon with all its projects has limited attention it can spend. Becoming a bank isn't something you half-ass, which is why they'll just continue to do cobranded cards with companies who are already banks.

That doesn't make any sense. Visa & MasterCard are the intermediaries, not the actual source of the cash. They sell their merchant network, and recreating it would be hard (not impossible, but a lot of work not in Amazon's wheelhouse).

Chase or Citi or Wells Fargo or whoever is the bank that needs reserves and fronts the cash to the merchant, and earns on the interest rate and fees and takes the risk on defaults.

cschneid··on How Discord Scaled Elixir to 5M Concurrent Users
> like Sequel

Ecto can do a reasonable impression with its DSL & direct use of tables. You don't need to go through the whole stack of schemas and such.

What in particular do you like about Sequel (over what Ecto is providing)?

Are there good resources / books on advanced BEAM? I'd love to know more of the nitty-gritty details of the VM, and how to make the best use of it.
cschneid··on NeoVim 0.2.0 released
So the nesting you have is Shell -> Nvim -> Ranger, so ranger is contained inside of a vim split?

Mind sharing some docs on how to do that?

cschneid··on Milk that lasts for months
My local store just started carrying small (1 pint) UHT milk. We don't use milk in our house, except as an ingredient in other things, so a pint at a time is perfect, and now it has a 6+ month shelf life, so there's less planning and feel-bads when it goes sour.
cschneid··on Considerations on Cost Disease
You hit on a problem I hear from my high school teacher girlfriend. It typically looks like:

1. One or several motivated schools attempt a new style of teaching / grading / curriculum. 2. It succeeds amazingly. 3. Other schools rush to grab some of that success.

The issue is that the causality between #1 and #2 is: "A motivated admin & teaching staff all working in the same direction can improve outcomes". While #3 is assuming: "a magic curriculum will do it for us".

Then after adopting the new-hotness fails, repeat with another new idea.

cschneid··on Typing Practice for Programmers
Agreed - people in this thread are too down on typing skill. It's not the only thing, but it is important.

Think -> decide that you need to extract a method -> using the keyboard, and your editor, do that -> think again.

The step w/ the keyboard will involve your custom editor environment, and typing. If you get it done, you can shorten the cycle from Think -> Decide -> Act -> Think, and get into a smoother workflow. If your keyboard and tools need your active thought on how to succeed, you get derailed in that Act step, and have to restart your thinking about the real problem.

cschneid··on Dow Hits 20000 for First Time
Other people have covered how the Dow is a mediocre stock index. The other half is that 20k doesn't mean anything either. It's just a number calculated by the math-function of the index.

The psychology is mildly fun, just like a 50th birthday may be more celebrated than a 49th. Round numbers appeal to us. But 20k dow says nothing more about the state of the economy than the 19.9 dow did a few days ago.

cschneid··on Experimental Cancer Treatment That Terminates Rogue Cells Could Arrive in 2017
Also not a doctor, but my dad has lung cancer (never smoked, just a "surprise, stage 4 lung cancer").

Specifically, he has the ALK mutation. This occurs in 3-5% of non small cell lung cancers.

He's on an inhibitor drug (a successor to Crizotinib) for this specific mutation. These drugs turned a ~6 month prognosis into a 5 year prognosis. But this set of drugs only works on this specific mutation. The cancer eventually mutates around the drug.

State of the art cancer drugs are really amazing, but they're still so far away from a cure.

That's $3.50 / 12pack - which is probably the average around here (non-sale price of $4, sale of $3, or best at $2.50). This is pepsi line at a Krogers, so name-brand product & store.
cschneid··on Ask HN: Is it ok to use traditional server-side rendering these days?
I know this is a joke post, but there's some happy middle ground that's possible too, without going full SPA.

If you render your pages and snippets on the server, a small amount of JS on the client can hotswap content. In the extreme of this idea, you get turbolinks from Rails where no real pageloads happen, but pages are rendered on the server.

But in the small, it can let you do a sprinkling of async calls where they make the most sense, and still keep all rendering of responses on the server.

cschneid··on The New York Times is buying the Wirecutter for more than $30M
The majority of links are to Amazon's product listing. Sometimes with alternate links (I've seen Jet.com and Homedepot.com type links). All reliable web stores.

You're right that its percentage based, so there may be a slight bias toward higher priced items, but I haven't seen it. I bought a recommended non-stick pan off thesweethome yesterday, and they explicitly talk about price range being good to go a bit cheaper and just buy a new one more often, rather than a more expensive one (to minimize the effects of wear that hit even expensive ones). So they recommend a cheaper pan than they could have.

The code entry form is 100% broken on safari [1]. It lets me type a number, then deletes it.

The cursor doesn't move to the next field, and the number I did type flashes in and then disappears.

cschneid··on Foxconn replaces '60,000 factory workers with robots'
Star Trek never really explains its economy. Why does Picard's family own a vineyard[1]? Presumably other people would like to have that. Why does starfleet headquarters get to be in the middle of SF. Don't they know that real-estate is expensive?

Even in post-scarcity world of things, there are non-divisible goods, like land, access to people (think, concert) and so on. So some form of allocation of resources would need to happen. Money is one way to do that. Others exist too like lottery, or government ownership are options too.

I'm all for post-scarcity, and think we can go a long way toward just having things be allocated and free, but you'll never get away from the miserable business of allocating scarce resources.

cschneid··on There’s Plenty of Space for One Trillion More Trees
You're describing one form of carbon offsets. A cap & trade system is pretty much what you're suggesting, depending on the specific implementation of a cap&trade system.

I've used this library (the promises part) and it works fine. Error handling as a proc is mildly awkward, but worked out fine.
cschneid··on Please, kill your darlings
I don't mind the implementation of this code, but 99% likely, it's in a method called `capitalize_sentence` or similar. If that is strewn through the middle of your code, it's probably breaking single-responsibility-principle.

cschneid··on Elixir-mail – Build composable mail messages
I like this builder pattern. Seems pretty similar to https://hackage.haskell.org/package/optparse-applicative as well, where you continually apply small functions to a data structure to end up with a big one.

Since Elixir doesn't have mandatory types, I assume there's no way to verify at compile time that it's a "valid" email (Has a recipient, and a from addr, whatever other requirements), and you'd have to check that in tests or at runtime?

cschneid··on A Group of American Teens Are Excelling at Advanced Math
It's easy to want to simply to steal from the rich, as you point out.

But that's not our current style of failure, it's "hey poor district, you're not up to snuff compared to the rich district. We're going to fire all the teachers, gut your union, and generally make your life hell. That's sure to make you do better".

cschneid··on InfluxDB is now InfluxData, a platform for time series data
They've gone through a few engines. They have a post about the newest one which isn't quite out yet:

https://influxdb.com/blog/2015/10/07/the_new_influxdb_storag...

We use them for storing "permanent" data. They slice up the data into weekly files, so if you don't access it often, it's no biggie to store a lot of data. If you constantly access data across time, you may run into performance degradation from a caching point of view (having to pull in the files from past, blowing caches of new stuff constantly).

:-/ Yeah, deunionizing would be great.... Private school teachers get paid much less than public [1], with the bonus of being fired any time. Instead, when school districts attempt to bust the teachers union, they do it in order to funnel money to charter schools, often religious [2]. These charter schools have selective admissions, and often won't keep children with any sort of difficulty [3], which artificially raises their test rates, and hoses kids who need the help.

ugh, summer argument.

First: teachers typically work days not on the student's school calendar, so it's more like 39 or so weeks by your calculation.

Second: they work WAY more than an 8 hour day. Last night she did 7am - 4pm in the building, then 2 or so hours at night grading. (and that was a light day since she had gotten her planning done previously this weekend).

Third: summer is where you can finally catch up and plan classes. Girlfriend did a major revamp of her AP US History class so she was in-line with the new standards. Last year was Western Civ revamp. Next year will be the standard US History class.

You're right, benefits are in-line (not better, just in-line) with corporate america. Mediocre, but existing health care. A pension style retirement plan that's reasonable, but at the mercy of underfunding by politicians (which seems to be expected at this point).

Given 20 years, and a doctorate degree $65k. Beyond 20, it goes to letters on the pay scale, and I'm not sure what the requirements are to move up that.

No teachers in this district are making money suitable to their training and experience.

cschneid··on 14-Year-Old Boy Arrested for Bringing Homemade Clock to School
At the teacher level, they are underpaid. My girlfriend is a high school teacher w/ 4 years experience, a masters degree in her topic, and works 12+ hours a day (not kidding, seriously all day).

She makes $35k / year.

If she wasn't lucky enough to have an engineer paycheck behind her life, she simply wouldn't be able to do the job.

It's likely that funding gets allocated in stupid ways, but the whole process is inherently expensive. Managing thousands of employees, dozens of buildings, updating equipment, training, etc, etc. It's a hard problem, and we've basically just decided that only "dedicated" workers should do it, which is code for "willing to be underpaid compared to qualifications".

From my reading, it appears to hook up to a Jenkins server, potentially that you control, so it can do anything Jenkins can, which includes building windows artifacts.
