> ... extremely high-IQ people ...

Don't underestimate the drive for people to lie or greatly exaggerate their achievements over the internet.

I personally find the post not entirely believable. E.g.,

- First she says "I had learned nothing beyond sixth grade math: no algebra, ...". Then she says "I had been lucky enough to be introduced to ... some algebra ..."

- "You see, I had no formal education". Oh wait, that still leaves out the possibility of thousands of hours of khan-academy, and youtube and what not, for math, physics, programming, during high-school, summers, evenings, freshman college, sophomore college, etc, etc. (Yeah no.).

- She was ignorant in math and physics in June 2012, took a QFT class around Dec 2012, and had an eye opening experience. It's good poetry but not clear what she meant by that. (could be as simple as sitting in a QFT class without credits, and being able to follow some of the discussion)

- She was taking QFT in Dec 2012, and yet she graduates with BA in physics as last as May of 2014 (from her profile page). So very likely QFT was a giant namedrop, and if you ignore that, spending 2 years on undergrad math and physics coursework, when you've already taken logic and set theory, leading up to a bachelor's degree is pretty routine for most students.

- She worked on the ATLAS project. But. Doing data analysis and "helping design electronics". That sounds like a computer nerd who liked to dabble into physics just for the sake of picking a major for the degree (not that hard).
The C Preprocessor Macros
Warnings and static analysis tools are good, but wrangling them across multiple tools, architectures, and coding standards is hard. Really hard. Different compilers will throw warnings for different things. Linting gets crazy. A customer might ask you to run your code against a MISRA ruleset. A different customer may have their own coding standard. The two standards may contradict each other in areas.

Did you know that printf returns a value? Aggressive linting tools will throw a warning about an unchecked return value.

So is printf("hello world?\n") wrong? And (void)printf("hello world\n") right? I don't know anymore.
Indeed. And I was hoping that a rundown of 2FA from a BSD guy would mention this bug.
I cannot imagine such a product/feature could exist on the market. This makes Microsoft's anti-trust issues with IE look like a joke in comparison.
How does one define `native`? To me, native is using the platform API's exactly - 1:1 - with zero abstractions. With Xamarin you do exactly that, in either csharp or fsharp. When using Xamarin a UIViewcontroller still is a UIViewController, you'll be directly interacting/pinvoking the underlying APIs that you already know and potentially hate :p (cough Android).

See http://continuous.codes/ for an example of what can be done with F# and Xamarin.
Something cool you can do with React is create an intelligent `Heading` component that wires into context to determine where it is at in the tree. It could then adjust it's actual HTML heading element accordingly. So for example, when you have a `Heading` inside another `Heading`, they render to `h2` and `h1` respectively.
Would love to see more details on what actually goes down on the nitty gritty level -- it sounds like the business hemorrhaged money for quite some time and given that you didn't have investment it'd be great to know how you got from there to having the capital on-hand to start running fiber.

How does the Ikea handle hold up after years of use?

My concern is that every time I unscrew a Moka pot, I'm pressing against the (plastic) handle and worry one day I'll snap it off (or mess up the lid hinge). I wish someone would come up with a better shape for a user to grip and unscrew the Moka-style coffeemaker or a different type of attachment.

I know Alessi's 9090 clamps to the base, but it's also 5x more expensive than the original (and lacks the simple beautiful of it).

Try Blendle[1]. Disclaimer I use their service and like it.

They let you fill your "wallet" with money which doesn't expire, and then they give you access to a bunch of different newspapers on a per-story basis for a variable amount of money per story based on the newspaper. So if you were spending $20/month on a NYT subscription you can put $20/Month into your Blendle account and read the stories of interest on the Times, WSJ, Post, Economist, etc and often have money left over. They have a generous "don't like it and we'll refund your money" which is quick and simple to use (I've used this probably half a dozen times when the article turned out to be just fluff). The articles have no additional advertising, render well on mobile or desktop or tablet. I dropped my NYT and WSJ subscriptions and read them on Blendle, that has cost me significantly less than the combined subscription rates.

> By focusing on what they would have done in the victim's place, they're re-framing the event as somehow the victim's choice and thus, at least partially the victim's fault.
That is a form of victim blaming. Full stop.

I think I understand what you're saying, but that's a pretty extreme stance and one that I don't agree with. You seem to be saying that a person's actions and decisions can not possibly have any effect on the situation, simply because the situation is undesirable and because the person is a victim. That view removes any notion of agency in the person in question. It removes the acknowledgement of free will and offends the dignity of the individual as an architect of their life. It's a kind of extreme infantilization.

Now, before you're led to believe that I'm advocating some kind of honor killing of adulterers, let me assure you that I absolutely am not. I find that extreme to be completely abhorrent and void of reason. From my vantage point, I believe that I'm standing precisely in the middle of the two extremes, being careful not to fall into the trap of either view.

It's a nightmare of twisty dependencies. You can either run the obsolete version in your distro or be prepared for a world of pain.

And it's made even worse because Qt decided they couldn't be bothered with binary compatibility so a whole bunch of things dependent upon Qt all broke and lots of things now all need to get fixed.
The thing is, you know what you're doing. He makes a fair point in that his target audience is people who don't know what they're doing, which is inevitably going to lead to people downloading "brand new updates" that are full of malware, or worse, backdoored.
An interesting business idea if not a depressing future.

Realistically, with all the various ratchet terms in Snap's financing, how many of the 2k employees will see very significant income from the IPO? By very significant, I mean >$150-300k per year in wealth creation adjusted for # of years it took to vest.

I honestly suspect not too many. A majority of the money that people will earn will just offset the difference in salary between Snap and larger more established companies that give out liquid RSUs - like Google. Plus Snap significantly backweights their equity. So the people who can cash out on all of their equity are a small percentage of the 2k employees (since it's still such a young company) and most employees probably haven't vested the full 4 years.

Still, the IPO will have an impact on the local economy - but probably not as much as is being purported.

Maybe someone with more experience in large financial liquidity events like this can chime in?
Out of the 1900 employees, how many are actually going to become millionaires at a company like Snapchat?

Where does Google Prompt 2FA fit into that scale? I'm unclear if it's it's roughly equivalent to Hardware U2F, since you would need to compromise google's push service, and gain access to my phone in order to bypass. I currently use my Yubikey, but I like the idea of Google Push.
My first thought was that the opposite was true. The immune system attacks healthy cells, increasing inflammation, thus stress. Thereby lowering the normal immune system and allowing cancer cells to flourish.

Unless you're talking about all-encompassing diseases (I can't think of any off the top of my head). Otherwise, I don't think Celiac/MS/Diabetes is fighting any cancers.
Awesome news. But is that video meant to show something? I sure cannot make out what it was trying to say.

So you are telling me a valid optimization for Go is to elide the entire contents of all goroutines?

And by that argument, since main() itself is an implicitly-called goroutine (so far as I know), then the compiler can elide the entire contents of main() too, and then the rest of the contents of the program.

This is an unsigned int, so the expectation would be to do integer division, which would not get you the same result as multiplying by the inverse.

I welcome alternative business models. The current trend is destroying quality news organizations and leaving consumers wanting.

Another option is the pay what you want model. This would be a lot easier to implement and would eliminate the possible backlash.

This morning I investigated the WSJ. After the intro period discount expires it's about $400 a year - a lot more than it's worth to me. Instead of getting $100 or even $200 from me they get nothing.

Pay by the article services like Blendle show promise, but they really need to work on the interface.
Don't punish them for paying late, reward them for paying on time.

I too played around with k8s but my issues were even more basic: It's darn near impossible to deploy it on a platform that deviates from their expectations.

The docs seem to expect that:

- If you're not letting managed services do most of the work for you, you're running on one of CoreOS, Ubuntu or a RHEL derivative

- You know all about "CNI" and how it magically makes everything work

- You know that the default "security" is none at all

Deployment is just so much harder than it should be. Fundamentally (I discovered far later on in the process), Kubernetes is comprised of roughly the following services: kube-apiserver, kubelet, kube-proxy, kube-scheduler, kube-controller-manager. The other dependencies are: A CA infrastructure for certificate based authentication, etcd, a container runtime (rkt or Docker) and CNI.

The steps for setting up a simple installation should be able to fit on a single page. If it weren't for a bug crippling my cluster, I would have done it myself (it seemed to be running but a bug with cadvisor's disk space detection messed it up to the point where it was useless).

To get a handle on what I mean, have a look at the docs for Ceph, another reasonably complex distributed system. Here are the manual installation docs: http://docs.ceph.com/docs/master/install/manual-deployment/. It's a list of commands to run and a basic idea of what the config files should look like. Following that guide actually results in a running Ceph cluster. Now have a look at the manual installation docs for Kubernetes: https://kubernetes.io/docs/getting-started-guides/scratch/. It's a bunch of links to other parts of the docs, pretty much no practical guidance on how to actually set up the cluster and the few commands that have been suggested are mostly outdated (for example "--configure-cbr0" doesn't exist on kubelet anymore). Following it can result in a working cluster but only with a lot of additional work and study (it doesn't give you anything on networking, which is essential).
The function with a long sleep also returns as expected, and is just as much a part of that particular algorithm as the quadratic implementation.

Those who do not remember pets.com are doomed to repeat it.

This IPO is going to wipe out the unicorn bubble. The valuations for this company are utterly delusional.

It's being pumped on all the investment forums by people who seem to honestly believe that the embarrassingly dorky Spectacles are going to be the next iPhone, even though investors seem to be the only people who have even heard of the thing.

This IPO is going to tank.

Snapchat has 1900 employees? That's way more than I expected.

For comparison, that's 5x the size of Valve, and around 2x the size of Riot Games. Snapchat is doing nowhere near the amount of work being done at either Valve or Riot, as far as I can tell at least. So is this just a case of "growing because we have money", or is there in fact a legitimate reason behind such a large workforce?

Zach Holman recently blogged about this:

I saw GitHub’s valuation move from sub-$10M to more than $2B; beyond that, GitHub is turning a decade old this year. Traditionally, this would be a great point where lots of little companies get spun off from this created wealth, and employees and former employees would be able to help with that.

In reality, I can probably count on one hand the number of people from GitHub who are in a financial position to become true angels. This is far from a problem unique to GitHub; the entire industry is concentrating its cash in a select few.

We could certainly have arguments about the allocation of natural resources and the merits of propertarian vs. antipropertarian societies, and I've done and enjoyed a lot of that, but it's out of the scope of this particular argument. In this context, the fact that government will punish a person for taking what is considered the property of another person is not in the same class as a fine or imprisonment for choosing to reduce one's taxable income.
Other than the mentioned advice of going to office hours with a purpose, I would say a golden way to get your professor's attention is to read their papers (select the top k most cited/interesting/whatever heuristic works for you). After doing that, you will undoubtably have focused questions to ask that can lead into discussion that will implicitly signal to the professor your interest/curiosity/passion (don't bog yourself down in the low level details). Reading papers is good practice anyway if (a) stuff like independent study intrigues you and (b) you want to stay current within your field of interest.
