Disclaimer: I work at Nubank, nice to see it posted here. This video is now one year old and it's nice to see how the technology choices at the start are still paying dividends.

Datomic in particular is a pretty smart product backed by solid concepts (RDFs/triplestores, event sourcing, immutability, querying engine on the client side, datalog), something companies end up re-inventing in-house further down the line, so it's nice to be aware of the architecture even if not intending to use it.
That's a superb attitude. Someone I know that ended up at Google was quite surprised that he indeed was the dumbest person in the room where up to that point he'd just about always been the smartest. then he started learning for real.

Imo, a built-in wifi module on the Pi0 would have made it massively more attractive. That way it can be put anywhere with just some sensors added. The SD card is ok, it requires no extra stuff and can even be handy for experimenting, but just adding wifi (which you want in >90% cases if you ask me) means adding a powered hub. Armv7 would have been nice for Ubuntu (Snappy Core or not).
That's just a stupid, slanderous comment. Do you have any reason to say such a thing? Can you please give us links to some of the many pirated courses?

Firefox's deal with Yahoo (or any other search engine) is only valuable so long as Firefox has lots of users. And Firefox's market share has been dropping for years now. That's what the author is worried about.
Hmm. I hate to play the skeptic, but this "HMD vortex generator" looks like a cold fusion device. It somehow fuses deuterium nuclei into alpha particles while their electrons fall out and are harvested. On top of that, the slideshow claims that the rupture of the hydrogen bonds in water generates electricity (!).

The fact that it needs both a capacitor and a battery bank to be able to output electricity seems sketchy, too.

Edit: The homepage is full of UFO and conspiracy stuff. So, yeah, it very likely is a scam.
While I agree with the basic argument that we are hurting ourselves with an irrational aversion to nuclear power, some of Thiel's arguments seem weak or overreaching. The worst, in my estimation, is this:

> Critics often point to the Chernobyl accident in the Soviet Union as an even more terrifying warning against nuclear power, but that accident was a direct result of both a faulty design and the operators’ incompetence. Fewer than 50 people were reported to have died at Chernobyl; by contrast, the American Lung Association estimates that smoke from coal-fired power plants kills about 13,000 people every year.

So on one hand you take the failure of a single nuclear plant, and count the direct, local deaths from that. On the other hand you take the sum of all coal-fired plants, and count the number of global, indirect deaths from them. OF COURSE the latter number is going to be bigger. The comparison is dishonest.
In general, since the article is titled with an adversarial generalization, Social Justice Advocates need to do a better job of projecting the empathy and inclusionariness that the most vocal of them demand of others, instead of making bullet points of how other people need to change their behaviour.

They might find that empathizing with others may give them the insight they need to to influence the cultural norms and social behaviours they wish to change.

Relevant, but not entirely on this point:

That absolutely mirrors my experience - I never spoke to anyone in Sicily or Venice who didn't immediately switch to non-dialect Italian as soon as they realised I was a foreigner (fairly obvious from my fair hair and blue eyes!) who could hopefully just about understand Italian but plainly couldn't understand their dialect. I did once watch a play entirely in Sicilian; it was very beautiful and mostly incomprehensible to me!
I'm all for innovation in storage and think there might be a breakthrough at some point. But this goes to the heart of it. Right now a fully renewable grid that matches what we currently have is not financially viable. Not saying it won't become so at some point but it's a high hurdle. All things considered having close to 100% reliable electricity in every home in America for less than ~$100/month is hard to compete with.

It's been found that resource concatenation is still more efficient http://engineering.khanacademy.org/posts/js-packaging-http2....

And 'building for http2' seems to be advocating hashes in filenames without neccesarily walking the dependencies, which can have cache problems http://holloway.nz/r/hashes-in-filenames/

ES6 imports are static (you can't use JS to dynamically include a file) so this means transitive dependencies need to be resolved at build time, not by using a manifest file which resolves paths clientside. This also applies to (eg) SVGs that reference JPEGs because you probably don't want JS involved there either. Manifest files are a bad idea, except perhaps for instructing webservers to tell browsers to preemptively download files. AFAIK there isn't a standard for this yet so a manifest doesn't solve the problem.

Ps. I've got a gulp build for http2-style packing and I'll release it on my github in a few weeks (same account as my username)
There have been companies that tried to commercialize rebranded Chromium: RockMelt comes to mind. They did not succeed.

The reason, to my mind, is simple: unless your underlying technology is better, there's little reason why users should choose your fork over the engine's official skin, which is always going to have better integration, will be first to get new features, gets security updates first, etc.

If this ever gets enforced it could be annoying for software that generates code at runtime, which may require quick access to some run-time data for particular instructions. It may be useful to force huge pages for dynamically generated code to improve pressure on the TLB. It can slow down code generation if the pages with code in it have to be converted to write and then converted back to execute every time a new bit of dynamic code gets added. Additionally, if the generated code instructions require access to a bit of dynamic data, it may not be able to actually reach a separate data page using immediate offsets to pc on some architectures (e.g. ARM).
Your evidence (of the absence of sexual dimorphism in the human brain) is that rats with identical genes can be trained in different directions? (Your second link is behind a paywall, for me anyway.)

> I'm trying to figure out how you would even begin to do an objective study of what you're looking for since by the time kids present meaningful interests, they're already irrevocably influenced by society and their parents' expectations.

https://en.wikipedia.org/wiki/Falsifiability

What you're saying is that your hypothesis (the absence of human sexual dimorphism in brain neuroanatomy) can't be proved false by any practical experiment. Nor can the Flying Spaghetti Monster.

Imagine you lived in a world (perhaps the world of 100 years ago) in which everyone believed in human sexual dimorphism in neuroanatomy. (BTW, here's the top link I get when I google that: http://cercor.oxfordjournals.org/content/11/6/490.short). Lacking MRI scans, these uneducated people give as evidence the fact that girls prefer dolls and boys prefer tin soldiers.

Your job is to convince them otherwise. You say: my theory is that it's possible that girls prefer dolls and boys prefer tin soldiers because of thousands of years of cultural conditioning, etc. You've offered an alternative hypothesis to explain facts that both of you observe.

You haven't even begun to explain why your hypothesis should be believed over the existing null hypothesis. Your listeners ask: what evidence makes your hypothesis more plausible than mine? That genetically identical rats can be trained to do different things? What does this tell me about human sexual dimorphism?

But actually, it's not as bleak as you think. Society today has enough parents and scientists who believe in the absence of sexual dimorphism above the neck, that this experiment has not gone unperformed. One example:

Just posting the tl;dr at the top of the article:

The Raspberry Pi Zero uses about 1/3 the power of the A+, or 1/6 the power of the model 2 B.

This is pretty awesome, as it's only about twice the power usage of a typical Arduino setup, so battery-powered embedded projects can start considering the Pi as an option. It helps, of course, that this is just $5!

I just got my mini-HDMI adapter in the mail today, so I'll be running a few more tests to see if there are any other major differences between the Zero, the model 2 B, and the A+/B+ (I currently use the A+ for most small projects right now, and the 2 B when I need a little more CPU).

The power consumption was the number 1 reason I couldn't use the PI in most of my projects so this is super exciting (the number 2 being cost).
My point is that it is, in fact, a prohibitive sum of money. I'm arguing that realistically, if Firefox were to make a donation drive, it would be nowhere near what they currently make from Yahoo, the Wikipedia figure gives a pretty real sense of scale in my opinion.
Unpopular opinion, but why should it be the community's burden to save a company that takes in over $300m in revenue (and apparently spends every bit of it) each year and, let's be real, hasn't managed to keep up or evolve along with the web? Why is it up to us to save them if they haven't really tried to save themselves?

I love Mozilla -- as a concept -- and I want to live in a world where Mozilla and its products still exist. But I can't remember the last time I used Firefox. And yes, it's partially because I'm a Mac user, but it's also because I can't choose ideals over a superior product.

That Mozilla languished on the desktop is sad, but almost understandable. IE languished too. (Microsoft was smart enough to replace it, even if the replacement did come years after it should have), but to languish on mobile is just inexcusable.

Firefox Phone was a project that could have worked for certain markets for a very brief period of time, but they had to know they started too late and were going after an ever-shrinking market when they started.

Sure, it would have been great for HTML5 to win over apps. It didn't happen. It's likely never going to happen (not until the next mobile paradigm shift happens anyway).

But instead of focusing on building the ultimate browser -- desktop or mobile -- I don't know what Mozilla did. I really don't.

But now they are struggling. And it puts the good work they do in jeopardy. And that's sad. But since when is it my responsibility (or yours) to subsidize a company with a $300m annual run rate who can't help itself. A company with very opaque goals and no roadmap.

I'm all for saving Mozilla but it needs to show me it wants to be saved.

It's basically same as the Gregorian, but add ten thousand to every positive year. 1 A.D. is year 10.000 in this calendar. We are now in year 12.015. Founding of Rome is 9.248. What good it does? Gets rid of the A.D.-B.C. confusion, for the most part of human history. Cons? Big years. IMO, I like it, it can be adopted as an international calendar (just like Esperanto is being widely spoken by the international community, eh).

That doesn't mean much, the educated professional upper middle class in the US earns more and has vastly more disposable income after taxes even when you count the costs of healthcare and personal savings.

And it's not like if you are living in Europe you won't have those expenses I lived in the Netherlands and now living in the UK and in both countries I still pay for private insurance because it covers much more and makes life so much easier for quality of life and preventative treatment.
The NHS is great if I get stabbed and need ER or if I get cancer and need treatment for decades but if I want to see an orthopedist or get good dental hell no...

The US also has lower overall COL, considerably cheaper housing (don't bring the Valley up please), cheaper food, cheaper consumer goods, combine that with higher wages especially in highly sought after professions and you get an overall better deal.
Seems you're out of quota.

If you have enough steady donation you can close Mozilla Corp which was created initially to handle business contracts with Google and a few other early business partners. Although Mozilla has many contributors, most of the bulk works are still completed by full time employees.

@antirez is all of the above to an amazing extent, however redis is one of the hardest projects to contribute code to from my own experience.

This is a very serious accusation to make, especially without tangible (as opposed to circumstantial) evidence.
Containers add their own considerable complexity to the stack. If the dependencies are complicated enough, or you need fast scaling/reconfiguration on the fly, then containers can certainly be a net positive. But if you're adding Docker, Compose, DCHQ, and whatever else to your stack just so you can put Nginx and some Ruby code in a container, I'm questioning whether that ends up being a net benefit over Puppet/Chef + rsync.

This piece strikes me as downright dishonest. The table purports to be apples to apples, but while the HDMI adapter added in for the pi zero, the $13 HDMI add-on board is not included in the cost section of the CHIP.

An honest comparison would be $23 vs $24 with HDMI, or $10 vs. some lower cost for the pi zero subtracting out the HDMI cable. I'm also skeptical of including the OTG adapter. Maybe it's needed for some purposes, but it's not a generally needed component.

The CHIP appears to be better for IOT experimentation, but the PI is intended to be a general purpose computer, which also includes some hardware integration tinkering capability.
Drupal's community is what got me into OSS, even though the language (PHP) community seems to be at a strange crossroads currently.

I've also been somewhat involved in Ansible's community, and it's been nothing but a positive experience so far.

It's interesting to compare some of the different communities; some seem to value technical competence over diversity, some UX over architecture, etc. It's probably easiest to dip your toes in the water and just make sure you can get help early on—jump into IRC or forums and see how people react to some initial questions you have about the project.

My comment was more of a general observation of terms applied to different asset classes, not particular to your comment. Thank you for the clarifications though :-)
I agree. Leads and other management roles are more difficult to peg but usually this is known simply by the person's role. A good dev lead could be judged by the number of code review comments or % code reviewed. Since a lead is also responsible for the team, their performance could be judged by overall team measures such as % test coverage of the overall code base, amount of time a ticket sits around etc. The team's metrics may become a way to judge the lead?

But I agree, it's all imperfect. I also don't think these metrics would be the only criteria by which someone is judged.
