DNA is a lot less discrete that you might think. There's epigenetic factors and population proportions, for example.

But even considering DNA as just a 4-letter language with discrete characters, my point is that many, even most, small sequence changes to a genome (e.g. single-nucleotide variants) have small effects or no effect at all, which gives evolution a smooth enough gradient to optimize things over time. That's what I mean by continuous in this context. The opposite would be, for example, a hash function, where any change, no matter how small, completely changes the output. Hence you couldn't "evolve" a string with a hash of all 7s by selecting for "larger proportion of 7s in the hash function", because hash functions are completely discontinuous by design. But you can evolve a bacterium that includes more of a given amino acid in its proteins by selecting for "larger proportion of that amino acid in protein extract".
Cars provide definite economic utility. I'm happy we're moving toward self-driving cars, but in the meantime, even as a non-driver, I don't want them banned. We let you trade our safety for your economic benefit (partly because our current economy depends on it).

We've regulated cigarettes to the point where they're mostly a threat to those who choose to use them. We let you trade your own health/safety for your own liberty.

Choosing not to vaccinate doesn't benefit anyone and does cause harm to other people. We're letting you trade our health/safety for your own liberty.

If you want to harm yourself, that's okay. If you want to put people at risk for society's benefit, that's okay. If you want to put society at risk because you don't believe in science, that's not okay.

Granted, war sucks.
This is also one of those things that an optimizing compiler with profiler (or, equivalently, a JITter) can do. (I don't know if any compilers currently actually do so.)
> For some physics reason I don't entirely understand, the tires have better friction with a slippery surface when they're still spinning

Nothing complex about this, the coefficient of friction in most reasonable cases is higher when the two surfaces aren't sliding.

>Newer cars have what's called an "Anti-Lock Braking System (ABS)", but it usually doesn't work very well. I'm pretty sure it's just there for the people that have never driven in snow before. It's actually worse to trigger it sometimes.

ABS is far from new. It was introduced in airplanes in the 1930s and has existed in cars since the 1970s. It's rare for cars these days not to have it. It's also much safer than pulsed braking because the anti-lock feature is applied per-wheel and not globally, so you can safely steer for example.

Apparently ABS reduces braking distances on asphalt and may increase them on snow/gravel because in some of those situations locked wheels can actually brake more by digging into the surface. More modern systems probably fix that and I bet even the old ones are still safer in real situations where you need to brake and steer.

I'm completly bewildered by the current 3D printing fandom. Every FDM print I've see just looks... off. I certainly am impressed people can make these things casually, but from an aesthetic and even practical point of view, it just looks terrible. I can't imagine using it for some of the more interesting use cases I hear about like replacing a cosmetic part in your car or house.

I spent a bit of time on 3d printing forums and from what I can tell its just figurine printing and hobbyist screwing around. These photos are very telling:

Singular: Reimagining AngularJS in Java
My family in The Netherlands has 3 bins.

Paper, plastic and other waste, and greens (compost).

They also get charged per pickup, so it is in your best interest to separate as much out as possible/flatten it, and make as little waste as possible in the first place.
Daniel Kurka's talk from GWT.create 2015 on Singular, an Angular-like framework for Java.

Singular leverages GWT to generate Web applications, but it can also generate native Android applications (that do not use Web Views or Javascript), as well as iOS applications via j2objc.

It's a Java annotation processor based system that provides platform neutral and template-syntax neutral two-way data-binding.
Awesome! Really liked the way you proved (-1)(-1)=1.

After reading the 123 comments so far of this delightful discourse, I'm curious why no one has mentioned how we handle the immigration issue and vaccination? Does ICE check the health records or what? I guess those legally entering with visas etc are good... dare I mention illegals?
The title is definitely linkbait!
...apparently more people do need to hear them and pay attention, particularly to the part of "Always keep your safety belt fastened when seated" because I've seen plenty of news lately of violent turbulence and passengers being thrown around because they didn't pay attention and follow the instructions they are legally obligated to follow...which is why no personal injury lawsuit regarding unintended turbulence for an un-buckled in passenger will ever win, near as I can tell.

> Do you support a law forcing every eligible person to take vaccines or not?

I think that's both a more effective and humane approach to the danger posed by non-vaccination than the also-defensible alternatives of allowing people to make that decision but then legal prohibiting them from most public intercourse, or just punishing anyone who is found to have, as a responsible adult, chosen not to vaccinate themselves or their child to a disease where they knew, or reasonably should have known, an effective vaccine was available, without a valid medical reason, and where the person so unvaccinated then transmitted the disease to a third party, for battery or, in the event that death results, murder of the depraved indifference type (as well as, of course, allow civil damages against those responsible adults for the resulting harms.)
Vaccines aren't 100% effective.

I'm writing it to record the code practices that I have found useful in getting things right and gather advice and tips from others who have done the same.

Generating a source rpm is not required to build a binary rpm, so I don't get the point of this tool. All you need to build a binary RPM is a .spec file. The spec file can then determine how to build and package it, like using sources already on disk, downloading sources, using a list of pre-compiled or noarch files, etc.

Building RPMS is typically a platform-specific thing, because most distributions bastardize their systems to be incompatible with others' RPMs. RPMs provided by vendors and 3rd parties typically shove everything into /opt and depend on very little to work around this. If you want your package to be portable you should probably do the same.
Not yet. But you can signup for a 5-email crash course. It's being updated almost every day now as I add more content.
I have a strong personal stake in this one right now. I am the parent of a 2 month old who can not get the MMR vaccine for another 10 months. Knowing that I have to take my daughter on a commercial flight in the next few weeks scares me, especially with the recent news of the outbreaks.

You say "in the US." Does that mean you've found other countries to be significantly quieter? I don't think I have, but I'm genuinely curious about this. Have there been any studies on the average sound levels in public places (or workplaces) in different countries?
But is this in tech? I know several people who have gotten these type of offers but they have almost all be exclusively in the financial sector. And even more so in trading type positions as quants or analysts.
Sorry yeah, I communicated that poorly. "big penalties" is meant to mean exactly what you wrote. Spend some time studying why they went over and do a write-up on it.

I've found most developers hate documentation more than anything, and making them do work like this is a "big penalty".

I agree that software estimation is hard, but that's usually at the macro-level. Micro-level estimation, within a few percent is usually pretty reliable. What happens at the macro level is that those tiny percent uncertainties compound up and interact in all sorts of horrible ways.

But "do you think you can build the database connector and load the data by next Friday?" is not too hard of a problem, even at the junior level.

I think more importantly, if they come back and it's not done, but it's not their fault, they'll get comfortable coming to give you bad news, which is super-critical for macro-planning.

So, you support a law that every eligible person be forced to take a vaccine that has a small chance of death or serious illness? How does that square with your desire to not have other people's decisions forced on your own kids?

A more reasonable approach would be to bar non-vaccinated kids from public school and let private schools and home schooled children decide for themselves. That's the only law that I support.

I've worked with both systems quite a bit, and really like them both. The licensing obviously makes ELK a no-brainer for my personal use. But, to be fair to Splunk the average required knowledge for their end-user is significantly lower. For the crowd poking around here it seems obvious that ELK is the right choice, but when I am unleashing a team of helpdesk techs on a set of data I would probably have a much more nuanced consideration about the tools.

I'm kind of pointing out the obvious, but it's my two cents for whatever they're worth.
In England this is part of the "Vertical Drinking Establishment".

You reduce the numbers of chairs and tables. That means that you fit more people in and they have to hold their drinks. Holding a drink means you drink it quicker. They turn up the volume so you chat less, which also means you drink faster.

Shut the fuck up. You hit a cyclist with that car and I will throw you under it, motherfucker.

Seriously, the notion that brake pads are a conspiracy by auto mechanics is simply.. Words cannot.

Let's try this:

In driver's ed, they tell you not to use the brake as a solution to all problems. If you cannot follow those instructions, you should not operate a motor vehicle. Do not modify the motor vehicle to remove essential safety equipment because YOU cannot fucking drive.

DRIVING IS A PRIVILEGE!
I did PHP for many years before moving to Ruby and Rails and never looked back ... doing Ruby made me a much much better software Engineer and gave me a better understanding of Computer Science as a whole. Its not impossible to get this with PHP, but the fact is that the low barrier to entry actually works against it. There are way more amateurs screwing around and writing really bad code with PHP than you'd find doing Ruby, Python and (more recently) Javascript (wasn't always the case though)

PHP just has bad PR. It unfortunate, but its just the reality of the PHP ecosystem, and if you choose to program mainly in it, then its something that you have to accept and work hard to overcome.

Weirdly enough, I find quite a few startups/tech companies that I wouldn't expect to use PHP actually do. Pocket. Slack. for example then the usual suspects like Facebook and Automattic (wordpress guys). From my experience following Ruby on Rails from the beginning till now ... I think the these using PHP are doing the ecosystem a massive disservice by not blogging more extensively about the awesome things they're doing with it and getting more word out about the right way to do things. Thats the only way I see the perception of PHP changing.
The issue with Titanium is the direct manipulation of view objects via the proxies.

Much of what makes React Native special is that everything -- from the original React API all the way to the latest and greatest bridge stuff -- has been designed with the assumption that the bridge (DOM) is the bottleneck so everything is batchable and async.

The API that Titanium gives you is much more traditional OOP which means that developers can easily create applications that chatter over the bridge.
The other libraries intentionally left out shouldComponentUpdate because they don't think it's something a developer should have to worry about. I don't know of any evidence to suggest that React is faster because of this feature.

And declarative nesting is a feature of all of the frameworks I've come across, I'm not sure why you think that's unique to React. The advantage feature I would credit React for is the size of its community and influential advocates like you.

The report I linked distinguishes between acres and harvested acres, except for the 4x, I'm quoting the harvested acres. So I think graze land and such is not going to show up in those numbers.

I made a stupid mistake, there are 80,000 large farms, not 80. Damn it. At least that makes a lot more sense.
The issue is not just risk to vaccinated children, but risk to the legitimately unvaccinated - too young, immunocompromised, any other condition that's scientifically known to make vaccination unsafe. Those people can't rely on vaccination, so they must rely on herd immunity. When herd immunity weakens beyond a certain point, those people are completely vulnerable for reasons that have nothing to do with their own choices. When we talk about the freedom of some people to forego vaccination, we're talking about taking away these other people's freedom to participate normally in society without significant risk of contracting an often crippling or even fatal disease.

Not all children are able to be vaccinated for medical reasons (allergies, weak immune systems/cancer). They could also potentially carry the disease to children who aren't old enough to be vaccinated yet.

I was very impressed with Windows Phone's integration of Facebook, Twitter etc. I could see in one native-styled list all the updates and replies from all my connections on both networks.

Hopefully these Ubuntu scopes can capture some of that.

Yeah, I imagine it was for the people affected. Further, saying 60 out of 35,000,000 is utter ignorance (not unexpected): Not only are there not 35,000,000 teenaged girls in Canada, and the actual side-effects unknown (people have been conditioned to be embarrassed by the notion that it could possibly be vaccine related), the "serious benefit" is that it might marginally reduce the rates of treatable cervical cancer....maybe. Serious benefits indeed.

Vaccines are something that need to be black and white

This is profoundly ignorant.
RPM is a packaging format, not a packaging standard. Fedora has a massive set of guidelines. OpenSUSE has a massive and different set of guidelines, because it's a different distro with different goals. Mandriva, another set. And so on. The fact they all happen to use RPM is pretty much irrelevant.
I don't have anything to compare to, but Go seems quite fast. I would guess no worse than 2x C in this case, but I'm pulling that number out of my butt.

Actually I was originally going to write this in C but it started to be a PITA and I had the spontaneous idea that maybe Go would be the right choice for this (never used it before). It totally was. No way I would've had this level of results so quickly in C.

Being a big fan of Python and C, Go seems like a really good middle ground. Really happy to have learned it.
