I can understand the value prop to the consumer - but I have a harder time understanding why it's an actual business, and why existing credit card companies or other lenders can't eat their lunch with the flip of a switch.

The a-ha moment for me was that functional programming - in most real world applications - is less about "no state" and "no side effects", and more about "properly managed state" and "properly managed side

The end result is superficially different. That's the point - we like the flow of the end result! But the implementation is completely different, as it's pure functional compared to object oriented. "string".do_stu

Elixir (and some other languages as well) solves this with the pipe operator: some_array |> do_thing() |> do_another_thing() |> do_something_else() Even though Elixir is functional and aggressively not object oriented, if you squin

You'd be forgiven for thinking that all SWE positions are high-paying soulless FAANG jobs - those jobs get a lot of attention and are very appealing to a lot of people. But there are tons of other kinds of SWE jobs out there that aren&

It only needs to be "data-driven and backed by science" if it's making scientific claims. It's totally okay to write a book of advice about workplace interactions based on anecdotes or your own experience (there are man

I think there's a certain trap that many software engineer & technical types fall into with crypto. Crypto & blockchain are often portrayed as technically superior solutions to many problems, especially by non-technical people

The people here saying the label is "correct" are both wrong, and missing the point. The objective of the model is not "taxonomic classification", the objective is "video recommendation". The label, in the co

If you want to take this question to the next level (and beyond any current real-world applications), read up on Reversible Computing ( https://en.wikipedia.org/wiki/Reversible_computing ), which is the concept of perfor

I've used Rails for various products for 10+ years (and plenty of other tools for comparison) and really appreciate it for the productivity, conventions, philosophy, etc. But after spending most of this year with Elixir/Phoenix,

Yes, the advantage is getting the actual IPO price, rather than buying on the open market. For example, BYND IPO'd at $25, but shares hit the open market in the mid $40s (and climbed very quickly into the $60s). That kind of performa

My brokerage (Fidelity) does this for free. But the problem is not knowing about the IPO, it's getting an allocation. As a retail investor, it would seem my position size is not big enough to get any shares. I know this varies by br

Reading that article and the context of the quote, it appears that Carmack is using that statement to extol the benefits of functional programming styles, not commenting on abstraction.

Refactoring code is a continuum, from "let's do nothing" (0%) to let's rewrite the whole damn thing" (100%). There's a whole spectrum in between. While I'm a "never say never" kind of guy, I do

Given the innovation we've seen from some industries in these times, I'm surprised I haven't seen any in dentistry. I'm probably just naïve about the challenges – or maybe it's happening and I'm just not aware.

I would add: have a process or framework for evaluating and adopting new technologies. Sometimes new technologies end up as part of the stack through pure momentum (hey, we built this prototype...) rather than deliberate choice. Be mindfu

One critically important question here I think - has the startup achieved product/market fit, or gotten a strong market signal that you were building the right thing? If the answer is "no", then the tolerance for bad code goe

Like the author, I'm really truly loving Elixir. I recently wrote up some of my experiences with Elixir/Phoenix coming from a Ruby/Rails perspective - https://medium.com/swlh/3-months-with-elixir-phoenix

If you had the stomach for such a thing, you might want to look at YANG, a 3x leveraged bearish China ETF, which is up about 30% over the past 3-4 days. Careful though - it will move just as quickly back down if the Chinese market recovers

That's funny, because I often make the opposite point about SF. Living in the Boston area, there are areas of Boston that are as expensive as SF (Back Bay, South End), but I can go a very short distance out of the city (Somerville,

This might be the case "out of the box", but it's very simple to go multithreaded on the Cedar stack and avoid this issue (provided that your app is threadsafe, of course). You can do this pretty easily with a Procfile and thin: bundle exec

You're going to have to explain your math here, because I don't believe the diagonal is going to give you 40 (unless I'm visualizing the problem incorrectly). In fact, I believe the diagonal is longer than the naive solution.

Actually, I don't think this kind of standard iPhone app promotion advice is worthless at all. But like any business problem, not every technique works for every situation. I wish I had some better advice to suggest, but in my experience,
