No, stochastic gradient descent (SGD) needs a differentiable loss function (differentiable with respect to the trainable parameters). The stochastic bit is that you want to optimize the loss for the whole dataset but what you actually do is to do each gradient descent step on a small mini-batch of the dataset.

There might be extensions where you have some non-differentiable part where you just assume some gradient in back-propagation. Like Gumble-Softmax (https://arxiv.org/abs/1611.01144). Or similar is the reparametrization trick in VAEs (https://arxiv.org/abs/1606.05908). But that are special cases.

Stack Overflow Developer Survey
Yes, but in many places you can only do work in some months each year (because weather) and can only map the bottom if the ship is not reserved for studying other things (fisheries, ecosystems, geology, red tides, black tides, phyto blooms...). And people have children and family and teach duties. Your campaign just can't last for 12 months.

Having a ship in a port for eight months is also expensive and moving a big ship eats a lot of gaz, so for coastal areas... "We're gonna need a smaller boat".

For sure! IndieHackers is great and I hope to include many of those companies in the future. What we were trying to do was show that you could build big and substantial businesses. Too many people dismiss bootstrapping as a way to build lifestyle businesses when in fact it's a way to build public companies.

In some cases we featured some companies that had $10M+ revenues and extraordinary success in PR (Cards Against Humanity) or found some cool funding method (e.g. Kickstarter and CMON). LMK if there are any IndieHacker interviews you think deserve inclusion.

Thanks!

That's how we do it with our products (purchases include a subscription). A subscription consists of:

- A year of support on our forums (real company-provided support, not just peer-provided).

- All minor releases and bug-fix builds within the year.

- After the subscription has expired, you still keep everything that you purchased forever, including being able to download anything you own at any time (we keep track of all of that for you).

We do have some "catches" to prevent free-riders at the expense of customers that maintain subscriptions, notably that you can only renew a subscription at the normal price within 2 years of your last renewal. After that, we start to ratchet up the renewal costs until, at the 5-year mark, you'll need to (effectively) purchase a new license.

Also, we offer inexpensive direct phone/email support through a separate "support session" method that is not tied to your subscription. So, even after a subscription expires, you still have direct support options.

The key is that any arrangement be fair and beneficial to both parties. In our case, we get a steady, predictable stream of revenue, and the customers get support, enhancements, and bug fixes quicker and at less cost.

Aphex twin speaks to Tatsuya Takahashi

Maybe, but I don't know that we should be attacking someone's poor communication ability. I'm sure I've misunderstood at least one of your points too. Let's just focus on what was actually asked for: Use-case examples.

> OK, so you said they don't need a special generics, but then say that they do.

There isn't an all encompassing 'generics'. Generics is a broad category of different ways to achieve reusable statements across varying types, in a type-safe manner. To try and draw an analogy, it is kind of like functional and imperative programming. Both achieve the function of providing a way to write programs, but the paradigms differ greatly. Each with their own pros and cons.

If imperative programming is the best choice for Google, that doesn't mean the community wouldn't be better served by functional programming, so to speak. And when it comes to generics, there are quite a few different paradigms that can be used, and not easily mixed-and-matched. They are asking for use-cases to determine which generics paradigm fits not only the needs at Google, but the needs everywhere.

> Also: ASK GOOGLE.

The Go team is Google. They have asked Google. Now they are asking everyone else. I'm not sure how to make this any more clear.

> Either Google is important enough to it in a way that works for them, or the community is more important and they get to choose.

In the past Google was seen as the most important, and they have been widely criticized for it. This is them moving in a direction that favours the community. And they are still being criticized for it... Funny how that works.

All the while, being an equally good place to live (I prefer Seattle by leaps and bounds, many prefer San Francisco.). As a result of this, Seattle is also growing at 3X the rate of San Francisco.
This simple price correlation trading strategy will blow your mind
I am baffled how price action of stocks in global markets is such an accurate predictor of next day U.S stock prices, that too you get to know the % price move in a U.S stock (listed on NASDAQ, NYSE or OTC) half a day in advance due to the time difference! I am a big advocate of price driven trading and from what I read, this one's a solid solid strategy and probably the simplest one yet. Not sure many know about this hidden gem.

This will definitely blow you away...

Anecdotally that seems very common in the suburbs of Atlanta. We're lazy about our street names here. I live at X Road and X Court (for some value of X) and that's not the only intersection like that in my subdivision. If I had a good data set I'd check if it's actually particularly common here or if I just noticed it since I moved here.
IMHO, the juicer wasn't over-engineered, it was under designed. Whomever designed it wasn't given or didn't pay attention to cost constraints and didn't think hard enough about how to solve the problem in the most efficient manner.

A well designed machine would probably be more like a roller on a worm drive mounted on some stamped sheet metal. It would look totally chintzy but get the job done and cost a fraction of what the Juicero cost. It would still be a stupid product that would probably fail, but at least the hardware wouldn't cost an arm and a leg.
"Some held up the countertop appliance as a symbol of all that was wrong with Silicon Valley..."

Production of consumer luxury gadgets the masses can't afford is hardly limited to businesses in Silicon Valley.

Maybe I'm over-thinking it here. But humans have great capacity for later justifying an opinion about something based upon what turns out to be nonsense. I wish journalism today would be more understanding.

When I was a kid (in the 80s) I was home sick a lot and watched TV with my mom. It was full of kitchen gadget ads, and other home appliance type stuff we could never afford. The TV itself was a 10+ yr old hand me down (as an aside, I doubt the 1080p TV I bought in 2015 will last as long).

Lower prices? While the article doesn't mention any specifics, juice that retails for $7 per serving and juice that retails for $5 per serving is still addressing the exact same market.

The cost structure of a subscription-based, home-delivered, fresh, semi-prepared food product is not going to, even at scale, be close to price-competitive with a juicer from Bed Bath & Beyond and some fresh fruit from Whole Foods. Juicero will, by its nature, always be a premium product situated well beyond any home juicing options.
> There was no fourth Punic war because there were no Carthaginians left alive and free. Let's not even talk about the Assyrians!

What do you have in mind about "the Assyrians"? Control of Mesopotamia flipped back and forth many times until it was eventually conquered from the east by Persia. The Assyrians neither destroyed any land nor were they destroyed by any enemies.

It was common for conquered populations to be deported elsewhere in a Mesopotamian empire, and for conquered cities to be burned (particularly the local palace) -- that's why we have so many contemporary records. But there was no ethos of killing the people or salting the earth, and those things just didn't happen.

There is a myth that the late Assyrian capital of Nineveh was sacked, destroyed, and completely abandoned, but this is contradicted by a wealth of archaeological evidence showing that it was sacked, recovered, and sustained its population continuously for several hundred more years.

In that context it's the cheese that's being melted, not the sandwich. Melting implies some kind of state change from solid to liquid (or semi-liquid), which is in fact the case in a melt sandwich where the cheese is melting. In this case the slime was already in a liquid state so there's no change taking place and it would therefore be incorrect to refer to it as melting. It DOES look kind of like the car was melted because of the accident damage combined with being covered in slime, which is I guess what the title is alluding to.

The birth of VC as an asset class is generally considered to be in the mid-1940s and created by Harvard Professor George Doriot. The early employees of Fairchild Semiconductor built on the model in the 1960 and helped give birth to Silicon Valley. You're are correct that VC moved into the popular psyche in the 1990s in the run-up to the dot-com boom.

> For (2), are you looking for overloading arithmetic operators (+, -, etc.)? Do people normally consider that under the umbrella of "generics"?

Overloading is usually not a "generics" concern in most mainstream languages[1]. If you do a "type class"/"Rust-style-traits" (or even multiclasses) thing then it sort of naturally takes a front seat. Incidentally, Haskell fucked this one up horribly in some respects, see the "Num" type class.

Of course, e.g. Java could theoretically add an interface called Addable to complement Comparable which would sort-of allow generic "+", but they've chosen to not opt for that. The fact that the "first parameter" is privileged is also a bit of a detriment to such syntax conveniences. (I can expand on this, but it's bascially because that for "X op Y" and "Y op X" to work, they both need to know of each other. This problem can be solved by type classes, but cannot be solved by overloading, AFAIK.)

[1] If you do have overloading from the outset (like Java, IIRC), then you're constrained because you need to be able to "pick the most specific overload" in a "generic" context.

Exactly this. Any self-taught intermediate person will have learned some things, missed others, and the pattern of what is missed varies widely by person. Therefore it isn't, "Oh, you're intermediate, this is what you need." Instead it is, "Here are the basic things that you happened to miss."

So it may be valid to swallow your pride and do the basic course, most of which you know, to find what you don't.

Or to trust that you can fill in holes yourself on demand. (People's belief about how well they can do this tends to exceed their actual ability...)

Or to have someone evaluate you to find those blind spots.

Correction: This story initially identified hagfish as invertebrates because they don’t have vertebrae. Verge commenter bennyfactor pointed out that hagfish are in fact considered “odd” or “degenerate” vertebrates. He’s correct, and the story has been updated.
> The nature of the beast is that software requirements rarely change

Put like this, it's hard to agree with the above statement.

Following the spirit of the article, I assume the author means that the problem domain is pretty stable. But I've been in this for more than 20 years, and I know that requirements always change. Not only our understanding, but also the customer/user's understanding of their needs and priorities change.

They ran out of the old bundle that had two boxes (one with headset, sensor ,Xbox controller and remote. other one with touch controllers and sensor). And announced earlier than expected the new cheaper bundle: one smaller box with headset, touch controllers and two sensors. The new box has no Xbox controller and no touch remote.
