It is different though. The derivative of the L2 loss function w.r.t. the linear regression parameters is a "flat" function that is easy to derive by hand. With neutral networks you have deeply nested vector-valued functions. If you write down the chain rule, it suggests that you should compute the Jacobians of all the nested vector valued functions and then multiply them together. This would be computationally expensive.

The key idea of backpropagation is that at each layer, you only ever need the derivatives of the loss function w.r.t. the parameters of the layer, and the Jacobian-vector product with the derivatives of the loss function w.r.t. the layer outputs. You never need to compute the jacobians explicitly and you never need to do those high dimensional matrix-matrix multiplications.

These are not complicated ideas but they involve a combination of software design, calculus, and linear algebra that would probably not be obvious to the average CS undergrad.
I even suggest it as a good way to learn about relational databases, in general.

The only downside is if the reader is "spoiled" by a particular feature that's documented as standard (such as to comply with one) and subsequently has to work with one that lacks it or implements it less completely.

That's the type of company I prefer to work for. Given how much they are spending on salary, quibbling over a decent quality keyboard & mouse raises red flags.
Right, I totally agree. What is more, I think this same result could actually be sold without the pompous deep learning bullshit and be received quite differently. If they did not claim to invent the wheel, but rather modestly noted their observation (which in a limited way is actually quite cool - that is from a known - at least on this forum - deep learning skeptic like me), it would make a much better impression.

Same is true actually for many DL papers. They'd be actually cool, if they weren't oversold.
Again here would suggest you check out GLG, Alphasights and other expert networks. They deal with much more sensitive info than "interview prep,"and much larger dollar figures; they do this with 1099's and have no issues for their supply side (which are employees or former employees at highly regulated institutions).

You are not required by law to report 1099's to your employer from what I understand - but we still encourage them to check with employers before agreeing to join The Lobby.

Last point, we've learned that if you use marketplace features on Stripe or PayPal, you potentially don't need to issue 1099's if you make less than $20k in a calendar year, which we don't know any of our individual insiders will make even at scale (if they make $20k, I suspect they’ll find a way to make the paperwork work!)
I don't think we're ever going to end up replacing doctors, but in the same way that tech accelerates other industries, AI should accelerate healthcare. Tying "expert machine" to "machine learning" could massively improve the pace at which Emergency Departments can triage patients, for instance, or provide doctors another useful input tool when diagnosing tricky conditions.

Wonderful advice from the community here. I always defer providing references as long as possible.

There have been a number of occasions when I thought the outside recruiter wanted to make the reference calls because they wanted to make sure a weak reference wouldn't interfere with them making the sale. The hiring HR is happy for the recruiter to do the legwork. The recruiter makes sure their candidate is accepted.
It's unlikely that you'd be able to push trainsets above 220mph or 350 km/h in revenue service. Even then, the actual average speed for a Chicago-NYC run would be closer to 160mph, since you'd have to make some stops along the way, and there's no way you're maintaining 220 in the Appalachians. The shortest plausible route would be essentially the turnpike route (parallel the NJ, PA, OH, and IN turnpikes in a NYC-Philly-Pittsburgh-Cleveland-Chicago route), which is going to run about 800 miles or so--or about 5 hours. More importantly, you can't shrink the project to a smaller viable project--not connecting Chicago and NYC is going to give you a losing line, and not hitting that top speed is going to be too slow.

And Chicago/NYC is the "easy" connection. Atlanta, Texas Triangle, and Florida are simply too far away, let alone trying to reach across the Plains to hit Denver, Phoenix, and Las Vegas en route to LA/SF.

Almost correct. It requires either that the version is already on your system, or it can find an installation of pyenv configured in the standard way (and, on some quirky situations with OSX, configured but pristine--without any pre-existing Python builds). In the latter case, it'll ask you if you want it to automatically build and cache/install a Python of the specified version.

And yes, the names all suck.

I agree with not needing an RTOS and the undesirability of rolling it yourself.

However Red Hat Linux has passed just as many government and banking standards (FIPS, PCI, etc) as almost any other vendor (MS, legacy UNIX), combined with a 7-10 year maintenance cycle (with additional being able to be negotiated, if your the scale of a large bank / ATM vendor). SUSE, Oracle and other vendors could provide the same guarentees and other then having developers understand Linux / Unix.
We once lost a super promising candidate at the references stage. Guy was a star, we were going to pay him 180 base for a remote position from somewhere fairly affordable. That was a lot to us as a small startup, more than any other IC was being paid at the time. He loved the team, the product, the mission, the comp etc.

We called his previous manager (not his current one), one of his references, to ask him about his experience with the candidate. His manager spoke very highly of his past direct report, we were quite happy with the outcome of the call.

Except his manager then proceeded to counter-offer the guy with 240, once he realized he was on the market, and the guy was like "Hey guys, you're awesome, the mission is meaningful and all that, but I got a family, I HAVE to take the extra 60k, sorry". That was one day away from him signing. We couldn't afford to counter-offer, so that's that.

Lesson: the engineering hiring climate is vicious right now, you might not want ask for references from your star candidates to avoid getting a last second poaching. Backdoor references in general are a lot better, but you still risk disclosing information that will lead to them getting poached.

Posting that issue into an unrelated thread is not the way to get it done.

I'm not sure how you're involved in that project but that issue thread is absolutely not how to run an open source project, or even how to get an issue fixed.

You've got people offering to help and then a tonne of hangers-on. The issue needs to be split into very defined tasks and worked on methodically - otherwise it's just going to sit there and accumulate more noise for years.

>and stuff that was previously considered a goal of AI research is now just boring automation, and so AI is still a distant dream.

I think that's exactly right, which is what makes it particularly amusing to look back at Hubert Dreyfuses' apocalyptic declarations that computers can't do things that resemble human-like judgment. One of those things was supposedly chess, which required "insight", which computers can't have. But once computers got better at it than humans, everyone kind of forgot about it and pointed at new examples.
Generally speaking, the most efficient solution for a problem is the one that can't solve any problems more difficult than the given one.
Interesting that you mention Lehi. I’m going exploring this summer to see if I can open a satellite office there for customer service, sales & maybe some engineering too. At a 2 hour flight, it’s a pretty awesome place. I’ve hung out with a YC startup there and there’s good energy & drive with a reasonable cost of living.

However, I know things look good on paper and don’t always pan out that way once you’re actually there.

One of the things about SV is that I don’t fee quite so out of place and weird for wanting to work all the time.
Solubility of CO2 in water at 0C and roughly atmospheric pressure is about 0.001337 mole fraction [0]. CO2 molecules are 44/18 times heavier than water molecules, so that's about 3.3g of CO2 dissolved in a liter of water. Carbonated water is usually specified in "volumes of CO2". One mole of gas at STP has a volume of about 22.4L, so one liter of CO2 weighs about 2g. "Lightly carbonated" is usually considered about two volumes of dissolved CO2, so 4g/L, which isn't much higher than 3.3g. Assuming the packaging is sealed well enough to maintain a high percentage of CO2 within, and the temperature is low enough, it looks plausible that there would be a noticeable change in taste/mouth-feel. This is confirmed by a study I found showing average taste threshold for dissolved CO2 in water of 0.26g/L [1].

> I thought the surprise effect would be telling to my interviewers that the answers were not artificial.

I tried this once for a job interview. I didn't prepare at all besides quickly scanning the company website.

It was a disaster. The position was for a PHP developer, and I accidentally mentioned that there is a lot of crappy PHP code in the world, in a way that made it sound like I didn't like PHP (I don't, but that's besides the point).

It didn't help that the interview was with an HR person. If it was with another developer, I would've been more than happy to elaborate on my opinion that there is a lot of poorly written PHP code, and that it is very easy to write poor quality PHP, but it is possible to write good (or acceptable) PHP.
I fully agree with your last sentence. Sadly I don't often see that actually happen in practice. And when the notation isn't explained I personally tend to waste a lot of brain cycles trying to decide what the notation means because I'm reading material that I don't already know (of course - if I already knew the material I probably wouldn't be reading it).
I've been in the situation of an interviewer, having to painfully show the skills the recruiter edited into their resume to get them an interview.

I absolutely agree with OP about being worried about edits, except I generally take it to the maximum extreme and don't use dedicated external recruiters at all when looking for work.

> Moreover, you don’t see “Mercedes-Benz” or “Range Rover” ignites twice in a title.

However, I think one might if it were just a bit more exotic, like a Ferrari.

More importantly, if, e.g., Mercedes had recently been making headlines (arguably through their own efforts) about their new [1] hydrogen-fuel-cell technology, and it was that technology that was catching fire twice, I'm pretty sure we'd see their brand name in the title.

Sometimes they do inverse kinematics to place footfalls. That's the most advanced thing I've seen in any game, though.
It is falsifiable if you consider that a simulation would have limited resources allocated to it. The null hypothesis would be the universe runs in a way where a simulation couldn't cheat by performing a rough calculation at the hard parts, thereby spending a tiny fraction of what would be needed and produce the same observable result.

The idea that quantum fields exist in multiple states simultaneously until observed become evidence for a simulation, since a simulator could be deferring calculations on things not observed.

Also, the very program this article is referring to could be considered as evidence for it, since if a rough simulation can be made where the observable result is indistinguishable from a result where every atomic element in the entire universe was simulated, then, again, a simulator with limited resources would make do.

The law of conservation of energy is built the same way. There is no way we can test ways that energy is transferred that we don't yet know about, but this law is still considered true, because we have so many examples of it working.
> Those carriers give out miles based on total fare.

Sort of. They give out miles based on this, but often not the miles needed to accrue status (which often makes mileage accrual substantially more lucrative, as well unlocking free/reduced upgrade access). On United, for example, you accrue MileagePlus miles based on total price paid, but accrue "Premier Qualifying Miles" and "Premier Qualifying Dollars" based on the "fare", which is always far lower.
Exactly this.

I did some work on PubSubHubbub based federated social networks back in the FriendFeed days. Technically it worked really well, and we had a few nodes sending posts between sites with only seconds of delay.

But no one wanted to use it.

After I while I worked out it failed for exactly the same reason FriendFeed (and Google Buzz) did: federation is actually a weakness when there is a major player.

FriendFeed gave up and took the FB money (smart). Google Buzz gave up and was replaced with the completely different (and non-federated) Google Plus (which failed for different reasons).

The only argument for it working this time is timing. I've come to appreciate timing based arguments a lot more over the last few years, so maybe there is an opportunity, but I'm sure not putting any effort into it.

From the article: 'He once said, referring to homosexuals, “it’s their deliberate, disgusting, revolting conduct that is responsible for the disease.”'

For those wondering, like I was, where that quote comes from, it's from PEP 560 "Core support for typing module and generic types" - https://www.python.org/dev/peps/pep-0560/
I can also highly recommend this book. It's an easy read and would walk you through a lot of what you need to know if you're new to writing tests or want to learn to write tests for Django or Flask.
Potentially. Which is why I believe that it is more of a click-bait title than a meaningful discussion point.
The usage of the word "strictly" here is strictly sloppy.

Why is a typedef/typename better than using auto in this case? You can literally look up the actual type the auto keyword is deducing by looking at the function parameters two lines above.

How many new typedefs do you want to create for code like this? You are suggesting creating two typedefs for this tiny 4-line code only. Imagine how many typedefs you might need to create in a real and complex project. How is the mess of typedefs going to be any more maintainable than this?

There are places where the auto keyword would make it hard to understand the type and there are places where it won't. This is a place where the auto keyword does not make it hard to understand the type.

Don't use the auto keyword if you don't want to but pretending that there is no value in using the auto keyword by using weasel words such as "strictly" is disingenuous.
