When I was in business school, we had a case study of a large supermarket chain that carried 18,000 or so different items per store. The management team wanted to save on cost and narrow down to just the essentials the chain's customers bought.

So they did an analysis and determined that only 6,000 or so of the products they carried sold in any significant amount. The other 12,000 were niche items that sold in small quantities and made little money.

Before they nixed the other 9,000 products though, the company decided to make one additional analysis, of who bought what in what combination. And it discovered all those little items were being bought in small quantities by people who bought large quantities of the big items.

The analysis further determined that if the supermarket nixed those 9,000 niche products, it would no longer be the "one stop shop" for its customers. Those customers would only be able to buy some of what they needed at the supermarket, and would need to buy the rest elsewhere. If a competing supermarket carried all of what a customer needed, that customer would eventually learn to do all his shopping at that supermarket to save the hassle of needing to journey to 2+ places to get what he needed.

After this final analysis, the supermarket chain decided to keep almost all the products it kept on its shelves, eliminating only 200 or 300 products, instead of 9,000.

It was not so much that the supermarket was very nice and charitable to niche spices and exotic Asian sauces and imported curries and whatnot.

Rather, it was that the supermarket realized that if its customers could not find everything they wanted on its shelves, they would eventually find everything they wanted on a competitor's shelves instead.

In YouTube's case, no good competitor presently exists. But a big part of the reason why is because YouTube has sucked all the oxygen out of the video hosting and streaming niche by being a one-stop shop. If it stops being that, there will be a lot more oxygen in that niche again.

(that said, I do not think demonetizing videos with low view counts / subscriber numbers constitutes injecting oxygen back into the market. "Not letting" niche video creators user their platform, however, probably would)
As an NSP architect I can tell you the hardest resource to procure is experienced talent that can operate a production network without trying to move fast and break things.

Buying hardware with usable software is pretty critical when dealing with stateful services.
I'm surprised that no one has yet mentioned Andrew Ng's Machine Learning course on Coursera and to go a bit deeper, his deep learning specialization on Coursera as well. Along with the programming assignments it's a solid way to get your feet wet. And definitely second the suggestion of the fast.ai courses as well
This is false, OpenBSD agreed to the inital embargo on KRACK, the author wanted it extended, OpenBSD asked if they could publish a silent fix/patch, the author agreed, then later renegged, OpenBSD published it anyways, then the author got pissy.

The idea that OpenBSD broke a bug embargo is misinformation.
For a general audience starting at zero is almost always the correct choice, but many exceptions exist such as temperature ignoring 0 kelvin.

It's a detail trade-off. Starting at zero helps the uninformed, but will obscure details.
I assume the 13,000 supposed jobs require skilled workers being found to want to live in Wisconsin in a time of full employment. I also assume Foxconn wants to pay them wages similar to the ones in China. Good luck with that.
Is there any serious research on gamification of work?

I mean, the abundance of advice that tell you that to be productive you need to cut distractions is maybe evidence of the opposite. Maybe it is deeply wrong. I am most productive when someone distracts me with urgent and somewhat game-like short task. Maybe creative one, or a small investigation.

Small tasks, small random rewards seems like way to go for me. Can we gamify most of work?

Interesting idea. Columnar ETL can be quite efficient in some scenarios because frequently an ETL transformation (e.g. calculating a new column) effectively modifies an existing table, rather than creates a new one. This allows calculating only the delta, instead of re-building a new table from. This helps optimize performance and do calculations in-memory without slow disk I/O.

Another advantage is that it allows performing many transformations (e.g. filtering) directly on dictionary compressed data, without decompressing it. This works well in Vertica [1] (based on C-Store DB [2]) which was our inspiration for building a light-weight ETL for business users that also uses a columnar in-memory data transformation engine [3].

AI without tons of data is, well, overkill. That being said, it seems Google is sharing a few pretrained models, which is nice.
This. Where there is no ability to summarize or paraphrase there is no comprehension. We need to stop calling fast pattern matching intelligence.
Yes you can, without ever touching a bitcoin. CBOE offers cash settled bitcoin futures.
Fundamentals of a market really controlled by a few, which would be different than a large correction in the stock market over 2 days.
Completely disagree here. If you test this way you'll be sure to have a correct implementation for this dummy program. Further, if the test fails you now have to try and figure out what component caused the failure.

A unit test should test a specific unit; commonly a class. You should have unit tests for the interface of that unit (never private or even protected methods). This absolutely does not prevent internal restructuring but it drive you toward seeing your classes as individual service providers with an interface.

I don't mean this in a flippant way, but I don't think there are fundamentals that support BTC at any objective price, since so much of the value is in speculation, both good (excited about the future utility) and bad (got 2 git dose mad gainz).

Unless you were being cheeky and saying its going to zero, in which case... I think its probably worth more than zero.

Maybe I'm remembering it wrong, but I recall a point in time where it first rallied up to about $33 then crashed down to something like $2.
Yes, it is, it's when a correction becomes a crash. At least in stock trading the sentiment differs greatly between the two. Most people trading BTC don't have a clue about trading though, though the market will be a lot less predictable.
Probably he/she didn't, because as you probably well know the market can remain irrational longer than most (retail) investors can remain solvent.

I know someone who really wants to make products abroad cheaply and sell them in the united states.

I think -- I haven't talked to him in years -- that he would love to receive a call that says "Can you supply me with [insert product]? Can you get it delivered at X for $Y?"

I doubt -- although I don't know -- that he would listen to "What are your biggest problems? Do you have a tough time with finances or sales?"

Notes: Its very very math heavy but if you really want to grasp the concepts and the idea around each topic, this is one of the way to go.

Online Lectures:

I like how he explains stuff and adds some context behind the math of each topic.

This is kind of a masters degree course i created for myself to get knowledge of Machine Learning from bottoms up

First, you need a strong mathematical base. Otherwise, you can copy paste an algorithm or use an API but you will not get any idea of what is happening inside
Following concepts are very essential

1) Linear Algebra (MIT https://ocw.mit.edu/courses/mathematics/18-06-linear-algebra... )
2) Probability (Harvard https://www.youtube.com/watch?v=KbB0FjPg0mw )

Get some basic grasp of machine learning. Get a good intuition of basic concepts

1) Andrew Ng coursera course (https://www.coursera.org/learn/machine-learning)

2) Tom Mitchell book (https://www.amazon.com/Machine-Learning-Tom-M-Mitchell/dp/00...)

Both the above course and book are super easy to follow. You will get a good idea of basic concepts but they lack in depth. Now you should move to more intense books and courses

You can get more in-depth knowledge of Machine learning from following sources

1)Nando machine learning course ( https://www.youtube.com/watch?v=w2OtwL5T1ow)

2)Bishops book (https://www.amazon.in/Pattern-Recognition-Learning-Informati...)

Especially Bishops book is really deep and covers almost all basic concepts.

Now for recent advances in Deep learning. I will suggest two brilliant courses from Stanford

1) Vision ( https://www.youtube.com/watch?v=NfnWJUyUJYU )

2) NLP ( https://www.youtube.com/watch?v=OQQ-W_63UgQ)

The Vision course by Karparthy can be a very good introduction to Deep learning. Also, the mother book for deep learning ( http://www.deeplearningbook.org/ )is good
You forgot the biggest one.

8. An ability to pay for bandwith costs without going broke as soon as your service starts to grow.

I think YT is in a unique position where the scale of your service has to be massive before your costs become manageable. This reason for this is b/c you need to operate as a network peer and have the ability to do edge caching. The vast majority of players in this space and startups simply cannot compete on that level.
Two options off the top of my head:

1/ Use the CBOE or CME futures for this. Just need to signup with a broker and sell a contract.
2/ Borrow BTC frome a holder. Agree to pay some interest. Then sell that BTC.
You can short Bitcoin via the futures markets launched in December by CME and CBOE. https://www.fool.com/investing/2017/12/10/cme-bitcoin-future...
CBOE futures launched Dec 10 last year though, so they have only recently been an option.

I wonder how people trading those futures see the bitcoin market (my assumption is that many of them will be much more sophisticated than the typical "crypto" trader).
Hi Graham, thanks for authoring and sharing such an interesting topic!

You can open a short futures position in /XBT (1 btc contract) or /BTC (5 btc contract), but that is obviously not safe, and the margin requirements to even enter are insanely large. And they don’t offer options, so there really is no way to limit your risk.
@bane, thank you for your comment. It is very important to us to work with people who already have experience with visual languages, so please, stay in touch with us and use our forum / chat to tell us about your ideas! We would love to help you create things with Luna!

Your sentence about visual languages that tend to live in a very niche places is a VERY important topic to me. In fact I think I've got a very crisp answer why it is happening:

1) Visual languages are mostly not open and free.

2) Most visual languages are designed for a very specific domain use cases (like sound processing, 3d graphics, etc). People are afraid of limitations! Unless I'm 100% sure that I'm working exactly in this niche, if I want to process data / create software I would never choose a domain specific visual language, because the probability I'll hit its limitations are too high to take the risk. This is why we have developed Luna as a real programming language, so literally if you are able to do anything in C, you should be able to do it in Luna!

3) Almost every visual language is designed just as components you can connect. That's it, they are not tightly integrated with textual representation. This often makes working in these languages tedious - you have to create many nodes to achive what you can within a single line. In Luna, however, you can use any expression to create node. You can for example create node `(2 + _).sqrt`. You will get a node, which will allow you to connect one input and send data to the missing place in expression. It allows you to keep your graph clean and small.

Moreover, we have described in detail why current visual languages fail to succeed in our blog post here: https://medium.com/@luna_language/luna-the-visual-way-to-cre...

To anyone who has become a parent recently and wondering what you have done to your life: I feel your pain.

After my daughter was born I had dark moments. Boy, was I naive about having kids. It was by far the most exhausting task I ever had to do. Especially the first year was tough. Relationship with mother, work, self-confidence, everything went down.

But let me tell you this: it gets better!

My daughter is turning three and she has grown into something splendid.

I didn't expect this, but I can honestly say that she is giving me as much as I give her. She has her own personality and it is a lot of fun to get to know her better every day.

I still miss my old life, a lot, but now I get to have fun with this creature and can learn from her every day something.
If you look at most successful companies, high-cash-compensation comes after the company has become successful enough to afford it, not the other way around. Back when Facebook/Google were unestablished startups, their cash compensation wasn't anything to brag about.

> I do worry about the pretense that we can operate our states as a giant cartel/union who collectively agree to not sharpen their pencils "against" each other

Of course, no sane person will disagree with what you said. This is why we need international diplomacy (carrots and sticks) to force the world to follow suit. I think there are several problems and we can't please everyone. In my example, it is little consolation to tell someone in California that their jobs aren't going overseas. "Don't worry. It is just going to Texas. Nothing to see here. Move along." What good does it do to them? Should they just move to Texas following the jobs? What will happen is standards will lower everywhere.

Here is an outrageous idea (don't actually do this): disband these united states and all states individually join the European Union. We will quickly see how important the federal government has been for each and every one of us in the world stage.

The examples you list are the few obvious, controversial types. The majority of content creators who have been getting demonetized over the past year or two do not have a single shred of "bad stuff" in their content. There are people losing their entire income because they don't fit some algorithm that has nothing to do with (properly) categorized - or reported - content.

It doesn't help that there are apologizers who spread the idea that YouTube is somehow targeting "the bad stuff", when that is a very small fraction of what is happening. Everyone focuses on the sensationalist garbage reported by the media; meanwhile all the small channels that are playing by the rules are being left out to dry.

It's not necessarily because of political correctness. A person with a family background and who may have been brought up in the target country has language skills and cultural knowledge that it would be difficult to learn otherwise. Those are useful skills for an intelligence agency to have.

For example, a native Pashto speaker who spent their formative years in Pakistan is likely to prove a valuable asset, and it's hard to leverage that value without giving them access to sensitive information.

Want to Make It in the Gig Economy? Emulate Romance Novelists
Why couldn't you just have the color scheme on the web page invert if you click one of the unusual, dangerous live alerts, so you're immediately very clear that you've selected a non-normal action?

So:

-- Business as usual --

1. Click test alert

2. Confirmation appears.

-- Nuclear attack or accidental click --

1a. Click live alert

2a. Invert colors

3a. Confirmation appears.

Doable entirely client-side, no need for extensive server-side changes which all these redesign ideas require. And the fact that the webpage background just turned black is clue that you've done something out of the ordinary, especially at shift change (so you don't just blindly hit the confirmation).
Trabzonspor 25 yaşındaki sol bek Filip Novak ile anlaşmaya vardı – Actualtr
I don't understand all the hate on this site for Bitcoin. Yes it is speculation, but I rather have people speculate on something like a digital currency than on things like food prices or real estate. In my building 40% of all apartments are vacant because they where bought to store money, on the other hand there are 50 people showing up for every rental with a decent price. So, even if Bitcoin goes up to $250,000 it will not have the negative side effects of other forms of speculation.

This is certainly the first level justification, but it's somewhat unusual isn't it? Find the most repressive regimes in the world and there's a good chance you'll find most of the big western names happily advertising and helping sustain the regime. We could argue that perhaps it's companies working to satisfy the market, but the people that work to call out advertisers are most often a very tiny minority of all customers. And in any case things like boycotts rarely last longer than the 10 seconds it takes for a new controversy to erupt on social media.

So what is their aim? The only thing I can frame it as is a power play. Advertisers working together to collectively ensure they have more strict control on what they can be advertised on has the nice side effect of them getting to decide the fate of many companies dependent on advertising for revenue. If a company acts in a way contrary to the interests of advertisers, they thus gain the ability to destroy that company. Similarly, it allows them to elevate companies that further their interests. Put another way, I wouldn't expect a documentary detailing the behaviors of Coca-Cola in South America or Nestle's behaviors... anywhere... to see much in the way of funding. But a documentary detailing healthy at any size? That's some advertiser worthy content.
