I would say understanding databases was the biggest gap. It was the thing was most easily fixed and produced the most payoff. Writing my own toy ORM as a learning tool was the thing that made all web frameworks more intuitive.

After that it was more about how to structure code and work with other peoples' code. I don't want to go as far as to say design patterns, but in my hobby days I would just start writing code and then have to do code gymnastics to work around the structure I built. Now I take much more time before I ever write anything to plan.
Too complex compared to what? All other commonly used web infrastructure is complex in various ways.

In my experience building and running Kubernetes clusters for Fortune 500 companies is that actually it's much simpler, it's just different from traditional infrastructure.

Different != Complex.
As a former hiring manager, I weighted highly any evidence of an ability to sustain work on projects and bring them to completion (which could be demonstrated on technical and non-technical projects); and evidence of actual interest in technology beyond that it pays the rent (which evidence was more typically a software project, but could be writing or speaking).

Beyond these attributes as proxy measures for job-related abilities, having someone like this around can also help attract and retain other quality engineers — so long as the side hustle doesn't displace the work responsibilities (unless the job is re-cast such that those coincide).
The Uranium tetrafluoride itself is basically insoluble in water. But the fuel isn't really the issue, Uranium is a toxic heavy metal but in terms of irradiating the environment outside of a reactor it's not very radioactive at all. People always clamour over Uranium having a half life of billions of years but what that means is that Uranium basically doesn't decay on its own. It's fissile, so hit it with a neutron and you'll induce it to split, but once it leaves a reactor and is subcritical you don't have to worry about the radiation from Uranium.

What you do need to worry about is the radiation from the products of fission as those are the nasty components of nuclear waste. Not only do you have the direct products which have a tiny half life compared to Uranium, those direct products have a decay chain of their own and in most reactor designs out there those products stay in the reactor so not only do you have the decay to contend with, you also have additional fission since it's still being bombarded by neutrons. This is what leads to the toxic soup of radioactive waste, you get tons of isotopes of elements so while the fuel itself wouldn't be too terribly awful for the environment the partially burned fuel is dramatically more radioactive.

The fuel salt itself though if it's anything similar to what was used in the MSRE or FLiBe's new Thorium breeder reactor would actually be insoluble in water and would freeze, hopefully trapping the waste in the frozen salt just like vitrification of nuclear waste. I am not a chemist, and any knowledge I have on the subject is just the result of a hobbyist interest in the subject, but I would think that in the event of a MSR being sunk and breached that the frozen fuel salt would keep most all of the radioactive products dissolved in it safely contained.

Err, both of them can in practice, the only difference is whether the data is bought or self-collected.

In practice Volvo would probably just sell the data to others (i'm pretty sure they already do sell it to everyone from insurance carriers to you name it), and Google would probably just keep it.

Basic income is arguably that, and there’s some hope that it will happen in the not so far future (or rather, there’s a reasonable fear that without it, and with the structural changes to the job market due to advanced automation, we’d be f#cked).

Another way to increase safety would be to slow down traffic... a lot.

While there is some truth when it comes to elitism etc, my own (hard learned) view regards this subject is, that there simply is somewhat of a "gut-feeling" if you should or should not be raising money. This is not the same as that you "feel a need", i mean everybody always need money. The "should" is usually there when you have sales flowing in and you just need to hire help etc. Many founders already know the answer deep down(and they are good at ignoring it), even before the pitch.
Eventually we as a society will finally learn that the whole outside Management Consultant/Efficiency Expert trend in business and government is a racket. Consultants don't care about your firm in the long term. If you want to save money, audit from within your company/agency.

The point is that many WordPress users don't know what PHP is, they got some cheap web space, put WordPress up and run it for their website/blog. The hosted doesn't really care either, they want to be cheap. Sure, old PHP is out of support upstream, but RHEL and others still backport patches and there are only very few remotely exploitable bugs in the recent past of PHP, thus risk of a breach due to PHP (contrary to a non-updated WordPress/Drupal/...) is relatively small.

When tuning by making the open strings beatless, it's useful to know that tuning an interval until the beats disappear isn't the same as tuning to the equal tempered standard.

A just 4th (4:3 frequency ratio) is about 2 cents flat of an equal tempered 4th, and a just major third (5:4 frequency ratio) is about 14 cents flat of the equal tempered major third.
Good?

Amazon needs some more major competition.
Yes, I am aware. I mentioned it in the second sentence of my post:

> ... you can even install pivoting panels ...

And like I said in my post, installing these is cheaper and easier in a field than on every home. For one, you only need one "tilt computer" module that can determine the optimal angle for all of the panels in the field. More importantly though, moving parts will wear and break eventually, and it's a lot easier (and safer!) to walk out into the field and service them than scheduling appointments, driving to customers' property, climbing on roofs, etc.

Just for fun, I've built these. You don't even need a GPS module nor magnetometer, you just need a few light sensors, one or two small motors (depending on whether you tilt in one dimension or two), and a couple dollars' worth of standard electronic components.
You're using a version of the php software that is not receiving security updates.

While CentOS might be supporting 6.9 until 2020, that doesn't mean Redhat is going to be performing security updates on PHP. Ubuntu obviously is updated a bit faster than CentOS, however you still need to use PPAs to receive the latest versions of PHP.

> many, many developers and site admins for various strong reasons are not in a position to do so.

I'm not convinced that this is a valid argument. If these versions of PHP were still supported, sure, but they are not and that is the real risk.

> Please consider the possibility that you do not understand the real world in which many, many developers work.

I got through this whole thing and I still can't figure out what "the big lie" is. That it's hard to get funded as a first-time founder? No shit. In the post-YC era it seems pretty close to impossible to close a round with a professional VC firm without first having done some kind of syndicated, social-proof-collecting round of angel investors --- so if that's seriously what you were playing with doing, I automatically have a hard time taking your experiences as guidance. And since hundreds of credible startups get introduced to angel investors through accelerator programs, it's hard to skip the accelerators and avoid signaling risk.

Is the big lie that you should be careful about trying to execute a funding-first startup plan? Hasn't every bootstrapper been saying that for over a decade?

Good catch. :)

It might be hard to read in the gif, but at Square, we actually allow users to approve their own sessions. When this happens, it's logged in such a way that an oncall infosec person is paged immediately. Users know not to do this except in case of emergency; the whole point is to have an in-case-of-fire-break-glass escape hatch during, e.g., a critical outage in the middle of the night.

The logic for this[1] is currently in the approval script (and in the sample one provided, it does deny access). However, I intend to make this a responsibility of the plugin itself[2] shortly, where you can toggle between denying and logging. Also, it's pretty easy to take the output from `socat`, pipe it to GPG, and archive the session afterward, for forensic purposes. We plan to do this latter part as well (possibly through the approval script, possibly as a second plugin).

There is bit of a weird standard when it comes to censoring because of the nature of content, audience, culture and location. There is no perfect solution to this problem.

Example - If anyone shares gun videos on social network from a place where carrying guns is a normal practice it may not get censored that quickly or may not even get reported. This is because people feel it is very normal or part of their location specific culture. While on other end someone who maybe coming from an entirely different place or culture may find this offensive or a safety issue.

The article takes exception to the practice of funding people who disproportionately have friends and family wealthy enough to make a first-round investment, who are disproportionately white men, who disproportionately come from a handful of educational institutions, etc.

It's an odd dichotomy to assert that funding decisions that ignored those factors would be "willy-nilly."

Assuming intelligence is the best predictor of wealth (not sure if true), and that intelligence is highly genetic as said elsewhere in this thread (not sure if true), then parent's wealth being a good predictor of children's wealth would already be explained by intelligence being genetic.

So just because parent's wealth predicts children's wealth doesn't in any way make it impossible that intelligence predicts wealth too or that they'd necessarily be in conflict.

IIRC the video was released by the police the next day

> We have no reason to believe the police simply confiscated the video files on the night of the accident.

From my own experience, the police will take dashcam video evidence the first chance they get because it's the best data they can get their hands on while on a scene. Source: I had interactions with the police on two separate occasions (once when my dashcam happened to record a car break-in taking place as I was driving into a parking lot, and once when some guy road raged me). On the second occasion, they were reviewing the video less than 15 minutes from the time of the incident and had the whole thing resolved within the hour.

Besides, as I said earlier, Uber itself is making a statement admitting it was at fault, and the NTSB investigation has way more forensic data than the crappy quality dashcam video police released, so I don't see how doctoring the dashcam video would fit into the narrative.
Enter the Beta(variate) distribution.

The beta distribution[1] is a cool statistical distribution defined by BetaDist{a,b} (or alpha, beta, but that's too much work), where a is the number of successes and b is the number of failures you've sampled.

It has a number of cool properties, chief among them that given X = BetaDist{a,b}, then cdf(X, x) = the probability that the mean of the distribution you are approximating is less than x. It has a bunch of other nice properties too (like E[X] = a / (a + b), which should be obvious), but those aren't as relevant here.

So let's say that you assume a uniform prior. This is defined as BetaDist{1,1} [2]. this is probably the wrong prior. So you might have a better idea. If, for example, you believe there is a 10% chance of your rocket exploding based on some calculations you've done, you might use a differently tuned beta distribution, like BetaDist{9,1} or BetaDist{4.5,.5} if you were feeling uncertain (but in general it would likely be better to use {8,2} in that situation iirc). But let's assume {1,1} for now.

So you launch your rocket. Everything goes great. You update your distribution. Its a success. So you get BetaDist{2,1} [3]. So what is the chance your rocket explodes? Well the cdf of your beta distribution is the probability that the mean is less than x. So the pdf of the beta distribution is the probability that the mean is exactly x. So then

The integral from 0 -> 1 of `(1 - x) * pdf(X, x) dx` is the estimated probability that your rocket explodes on its next launch, since that's "for every value x, the likelyhood of the distribution being that one multiplied by the chance your rocket explodes given that distribution". For the one rocket case, this happens to be equal to E[X] = a / (a + b), so it's 1/3.

For the two rocket case, you apply reinforcement learning/k-armed bandit strategies like UBC1[4] or Thompson Sampling[5]. These are algorithms that will result in you picking the best rocket with as few unnecessary explosions as possible, provably.

You can see some related discussion I've had on HN about these algorithms [6].

From the closing paragraph: We should care about health, food, and education. But instead of seeing them as ways to prop up class dominance, we should improve them for everyone.

Sure, that's agreeable enough. But I can't tell for sure if the author understands the difference between 1) upper middle class parents having resources to confer material advantages to their own families and 2) faddish tribal markers that confer no material advantage. The two are mixed indiscriminately throughout the article. There's no benefit to enabling the lower 4 income quintiles to participate in the same fads embraced by the top quintile.

Being an overweight smoker really is bad for your health. It's not just an arbitrary tribal marker.

Breast-feeding infants is good for them.

Limiting screen time is good for young children.

Exclusively eating organic-certified food, or gluten-free food (without a supporting diagnostic test), is just a tribal marker.

Wearing exercise outfits to the grocery store is just a marker. Actually exercising isn't.

One upper-middle-class fad that is actually worse for children, omitted from the article: refusing to vaccinate.
