Think of emotion as predicting future positive or negative rewards. The value of a state (or action) is related to the anticipation of reward. The fundamental role of emotion is to select actions. Rewards types are basically hard wired by evolution into our brains and are related to safety, food, companionship, learning, creativity, curiosity and a few more. They simply identify specific situations and send reward signals to the part of the brain that learns to predict future rewards.

> It doesn't look like digital computation (not digital encoding) can produce such outcomes.

We have built such systems and they work with enough training, but their training must be as agents in an environment, not as a model training on a static dataset - think AlphaGo. I think AlphaGo has learned emotion related to the world of Go (in this case emotion is related to good-move, bad move, safety and danger), and its human opponents had a lot to say about how it felt to play against it.

Emotion is not something beyond AI agents. It's just how they plan their actions. They might not be human emotions but they are emotions related to their own activity and goals.
Good question. You need to compare apples to apples. Are we talking about file storage? payments? DNS? smart contracts?

in each of these, speed might matter, or size of the data, or interoperability, or high availability, or centralization, etc.
How can a blockchain be more efficient than centralisation? I once worked at a company obsessed with blockchain and asked the business person who never worked on anything technical in his life this same question, and he mumbled something about “cutting out the middle man” that he probably saw in a TED talk or read in Forbes. The irony is of course that a blockchain literally introduces millions of middlemen who all have a copy of the same ledger, and who all must constantly engage in a protocol to agree on the latest state of the ledger. There’s nothing efficient about it.
Crudely speaking is right.

I feel that what Apple is doing with the iPad is trying to create a whole new separate paradigm of computing with glass slabs, without re-using the good ideas from the Mac. Whether it's pride or something else, they simply can't make themselves do a dual-use operating system (e.g. support for overlapping windows, mouse, file management - while still having good support for touch), so they are forced to come up with totally new ways of interacting with devices. While that's pretty interesting and totally fine, there is also a reason why modern MacBooks (and computers in general) are the way they are, so all the solutions are second-rate, and it's why professional users will always feel limited when using the iPad for things that are not just watching YouTube videos.

I conjecture that blockchain only solves peer-to-Peter digital currency, I.e Bitcoin. I conjecture it has no business solution about supply chains or tracking bananas or weed or porn any other nonsense. Almost invariably, a central authority actually exists and is hidden behind buzzwords, or its a bad version of Git.

"Researchers attribute the blood-pressure lowering effects of beets to their high concentration of nitrates"

I don't get why Nitrates in beets are a good thing while they seem to be bad in spinach, kale and brussel sprouts.

The really "bad" stuff seem to be Nitrits that are converted from the Nitrites by cooking. That would go for all cooked vegetables, though.
They surely don't believe they have breached the law. For example:

The fact that the phone spying case was even accepted by the Supreme Court should be enough to confirm that the law wasn't clear. Had the law been clear, the NSA would have lost in a lower court and the Supreme Court would have refused to consider the case.

Tooling JEE, Spring or ASP.NET MVC, with server side rendering.

Eventually coupled with full stack CMS like Liferay or Sitecore.

For frontend either tiny pieces of vanilajs when dynamic code is really required, or something that is WebComponents friendly like Angular, if the backend is mostly composed of Web APIs.

Might not be fashionable, performance is quite good, and we get to focus on delivering instead of playing JS framework of the month.

Bullshit. Madpakke, consisting of open sandwiches on rye is still very common in Denmark, and was the bane of my childhood school years, though thankfully most office places has moved on to provide workers with a decent cantina, and more and more school children are handed money to buy their lunch.

As the article states in the beginning, these stale packed lunches are not much to look forward too.

I don't believe there is a good answer to this as details are missing. What scale are you trying to get to? What level of concurrency? How much state and how often is it accessed? And what are the skill of your engineers.

You could write a rails monolithic app on postgres if you're building an internal application 100 people will use. Or you could use Akka and Scala with all state in memory backed by an event journal stored in cassandra.

IMO Ruby, Python and Elixir are perfectly suitable but the last languages I would choose. I've been working with elixir for the last 1.5 years and have decided I don't really like it. I'm happiest writing scala - I get more done faster and less bugs make it into production. Event sourcing and Akka cluster allow some really interesting patters that move state into application memory. But those technologies require a much different, more involved skill and experience set to lead.

I'd probably be using Go or Scala if I had to start a tech company in a small city. Scala if I were in a large city with talent 100%. There is evidence that Static typic improves speed of delivery and it's easier to refactor/maintain. And it's faster (generally). Both languages are much more widely used than elixir.
Human eyes take in data that's not available to a camera. Fo example we can detect a single photon. We can also change the lens shape of the eye. And the brain uses more than just eyes to drive. We use our ears for example, and our vestibular system. And there are even parts of our body at work that don't talk to the brain... Our brainstem certainly handles many aspects of driving without talking to the eyes. So I wouldn't say there's an existence proof there.

Data compression isn’t the problem. DYNAMIC compression is.

And it makes data compression worse, because when EVERYTHING is loud, sounds that should have been masked by others are not.
It's the next-best solution. The only reasonable argument in favor that I've seen is that it is easier and more authoritarian (maybe be careful believing this is a good thing?) to set a hard cap. But a carbon tax can always be adjusted.

It's inferior in econonic efficiency and comprehensive coverage to a carbon tax.

And if implemented incorrectly, it becomes corporate welfare, and this has already happened. It has potential to be just another corporatist-cronyist scheme at taxpayer's expense.

And to date government and bureaucracy have been pretty horrible about solving climate change.

Carbon tax is a simple, elegant, efficient, effective solution. Most people just dont like the sound of it though.

Credit repair specialist
Good day everyone and happy new year, I had some nagging late payments, student loan, medical bills and a bankruptcy filed 2017. I had credit scores of 457 (TransUnion) and 470 (Equifax) in August 2018. I applied for a surgery loan in September but was not approved because of my poor credit profile. I needed a score of 750 and the bankruptcy removed from my report before I can be qualified for the loan. I had to seek for a way to raise my score and bring my credit profile up to speed because I had to do the surgery at that time. I made some research and I got a lot of good review and strong recommendations on DPROTOCOL a credit repair specialist who has helped a lot of people in the States so I decided to email him (DPROTOCOL7@gmail.com, +1 320 245 4036). After some few discussion he said he will help me. We got started with the process on a substantial agreement. After 8 business days he removed the bankruptcy, deleted other negative info, eventually raised my score to 798 and verified the changes with the 3 credit bureaus. I got the loan, went through with my surgery and I have DPROTOCOL to thank.
Hear hear! I don’t understand why Mozilla doesn’t prioritize this. Surely they have the devs to do it.
The data-entangle construct taking a string that it presumably evals looks like a security nightmare (and disallowed for good reason by many devs with CSP). Not to mention the innerHTML use (although its unclear if thats just as an example)... Without source it’s impossible to say what’s going on though.

In general I don’t really see what makes this good for real time applications (it seems kind of bad for them), but I’m guessing this is just a translation issue as the author doesn’t appear to be a native english speaker.
In a multi-agent environment an agent has to model its peers as well and learn to communicate to solve goals together. Dealing with other agents is one step up from dealing with objects. Emotion would naturally be linked to the actions of other agents as they affect the completion of one's goals.

The problem is that we must mandate by law software to being open, easy to use, modify and deploy with simple means, that's to guarantee our freedom and democracy.

Argo is pretty cool but I think it's different. Imagine developing an automation workflow with 20-30 different steps. In Argo you basically have to develop 20-30 different applications, compile them, build a separate docker image and push all these images to a registry.

In my opinion that's too much overhead and a configuration management nightmare as well. Additionally, what if one step needs to share information with another one? What if when this information is not trivial like a binary for example?

That fits well with neural nets, where noise plays a crucial role, from the random order of selecting examples into batches, to randomly dropping out synapses, directly injecting noise, or even starting prediction from pure noise (GANs). In RL the epsilon-greedy technique prescribes random actions from time to time, in order to better explore the environment. Noise, when used properly, makes neural nets better and more resilient.
Pretty good description. Seems like I still have a lot to learn on how to present an idea right. :-)

Correct, it's basically pre-cut parchment paper.

The thing to watch out for though is that the parchment paper is not suited for baking (mainly thinner and cheaper), we once baked a pizza on the matpakke type and it was a pain to get the paper off the crust.

Once someone told me:

>"popcorn is healthy"

They read that, and I have, too. It's true. But if your health is sensitive to high-glycemic foods, popcorn is not a good choice.

Actually that person became angry with me. "I read it, I think in the NYTimes!" "It said it right in there. You dont know what you're talking about."

This person had a prestigious degree. Sometimes I wonder about how critical thinking skills and tolerance of dissent is valued today.

FYI, that's getting to be a dangerous amount of spinach. You could die of oxalic acid poisoning. Probably 2 inches is OK if fluffed instead of packed, but at that point you ought to weigh it and weigh yourself and make sure you have excellent kidney function. You could also be setting yourself up for painful kidney stones if you make this diet a habit.
So when it's some silicon valley tech company releasing something as part of their tech marketing strategy it's fine, but when it's from Europe it's "Propaganda"?
I agree with all this, though if you're deadset on React (which is a great choice) and you know JS well, then I'd say Express is a better choice than django.

Also

> Do not use jwt

I heavily disagree with this. JWT has its trade offs sure, but if you want to start simple and have the most "cookie like" experience then use cookies and store your JWT inside the cookie.

Edit: To be clear, to get started you should use whatever auth your web framework of choice provides which is usually some "randomly" generated token that gets written to the db and to a cookie which works fine. However, if you need to customize it or if for some reason you're making your own auth system (not advised) you should make the token that goes into your cookie a JWT instead of a random value
No apologies needed. It was a fair assumption and I do agree with your points, although I think I've come to move more in the other direction the last few years.

Those perfect one line fixes are great but they approach their limits and eventually need to be refactored. This is natural and should not be frowned upon. Likewise you can't just refactor all the time, one line fixes are faster and less costly in all sorts of ways. The key is to pick and choose when to use each strategy.

I think we're too often looking for simple rules. There are none. Just a bunch of guidelines.
It can be used as an replacement for existing CI/CD tools but not exclusive. In my opinion Gaia can be used for every possible automation task. :-)

There are some very strange arguments in this article.

One claimed advantage of a web app is: "An App Store developer license costs $99/year, whereas a Namecheap domain is less than $10/month". Now, correct me if I'm wrong, but surely a year has 12 months, making it actually more expensive? I guess it's an advantage if you expect your business to fail within 10 months?

Also: "Browsers automatically translate text, so web developers don’t need to do much extra work to reach foreign users."

...

What? Presumably the author speaks no languages other than English. Developers of native applications could easily run their UI strings through machine translation if they wanted to - but nobody wants that because the results are at best unprofessional and usually nonsensical gibberish.

I agree and I would go as far as distancing myself further to guess that you just ventured one guess deeper.
Would recommend Vue as a front end framework. It’s much simpler than the others, and every web dev I spoke to in 2018 recommended learning it.

Backend, Flask for smaller stuff, moving up to Django or maybe Go for bigger stuff.

Database Postgres.

YMMV depending on what you’re doing, but the above is a good bet if you want to make the project accessible to other programmers, and it doesn’t need to quickly scale.

Hem, I't common in any country of the world, perhaps with different names, different food, different packing but the same principles.

In Italy is called "schiscetta" (read in English Skishetta), in Japan is called "bento" etc...

In few countries however such kind of "productivity" is considered a kind of (self) slavery and it's not really accepted. For instance in Swiss it not common at all eat in your workplace no matter the provenance of food because we do not live for work but the contrary. In French is common only for low-paid labors, mostly young at career start etc.

Have seen the different idea of productivity in few countries and their relevant economic level I think there is no real correlation...
Surely it meant to say, $10/year for domain registration? Either way, this is still nonsense. Besides App Store developer license can be reused for other apps and comes with other additional benefits.
>> “100 calories of ground beef contain 10 grams of protein, whereas 100 calories of baby spinach contain 12 grams of protein.”

That’s disingenuous because 100 grams of spinach only has 23 kcal and 2.9 g of proteins.

To get 1 g of protein per lean body mass, which is about the minimum we need in order to avoid muscle loss or fragile bones, in my case I would need more than 70 g of proteins per day.

If I were to eat only spinach, I would have to eat 2.5 Kg of spinach per day. Can you imagine yourself eating 2.5 Kg of spinach in a single day? You couldn’t, because it’s not possible.

So no, spinach is not a better protein source than beef. And as a matter of fact you won’t find better protein sources than meat.

Beans come closer, the problem with beans being that they are toxic and those proteins won’t get assimilated well.

N.B. calories is a useless metric, don’t fall for it ;-)
