You've heard of the progress of entropy and the "thermodynamic arrow of time" right? Time travel into the past, violating causality... it breaks the math used to formulate the most basic physics at a very fundamental level.
Developer is too general a term for deducing an ideal mindset.

A tester should be empowered by defeating the system. That's also great for some kinds of development (like in security). For some systems, it's better to be empowered by seeing the things you build grow as you act, for others, it's better to be empowered by seeing they grow by themselves after you act. There are places best fit by people empowered by ensuring no problem arises (also the dominant mindshare in ops), by comprehending things none could before, and by making hard things easy. There are probably places for other people that I'm overlooking too.

Testing is a much more standardized position.

It's hard to say if you're implying this is any different with other validation levels like OV and EV. The validation methods that CAs may use for OV/EV are the same ones they may use for DV. The only difference is that they also validate the organization's information of the certificate requester. In other words, someone with the ability to MitM traffic between the CA and the target's domain could still obtain an OV/EV certificate for that domain, they'd just have to verify they are who they claim they are on top of that (and they don't have to be the domain owner - there's nothing that says "only the legal entity owning the domain may acquire a certificate for that domain").
fair enough, but people cross reference because the total is often more than the sum of its parts.

The latency and power issues can probably be fixed, assuming a good end-to-end model, by using model distillation into a wide shallow net using low-precision or even binary operations. I don't know if that would be enough - we've seen multiple order of magnitude decreases in compute requirements (think about style transfer going from hours on top-end Titan GPUs to realtime on mobile phones) but the usual target is mobile smartphones which at least have a GPU, while it seems unlikely any hearing aids will have GPUs anytime soon... I suppose a good enough squashed low-precision model could be turned into an ASIC.
Charmed is a lot more stylistically conventional than Buffy. I don't think it makes sense to call either "the birth of TV as art"—TV has always been a medium for (heavily commercialized) art—but I think that there are substantial contrasts between. Buffy and Charmed as examples and influences in TV-as-art.

Time travel isn't forbidden. At least, there are solutions to the Einstein field equations that allow for the existence of wormholes between two points in space-time. But that doesn't mean there are wormholes in our universe, or that wormholes could be created (that last part is a little tricky, it's not easy to talk about causality when dealing with time travel). There could well be other laws of physics that prevent time travel, but general relativity seems to allow it.

We got along okay with Newton until Einstein came along and upgraded the model.
> People can't invoke the name "Linux" and exclude Ubuntu when it suits their narrative.

Why not? Ubuntu (along with Red Hat & others) is a commercial distribution of Linux, but it's not the only Linux. Users who care about their freedom & privacy don't use Ubuntu, because it includes proprietary drivers & does things like phone home.

Users of distros such as Debian, OTOH, do care about those things, and I think it's very fair for us to note that we find the behaviour of Microsoft recently to be quite remarkably sad.

I don't know just how many people did Unity successfully prevent from switching to Linux!

With regards to usability and customizability, IMHO Unity seems to get worse with each release, so eg. now it no longer supports screenlets, and even the "Unity Tweak tool" no longer seems to work for several useful "tweaks".

But, I just don't get why do people assume it's either "plain" Unity or back to Windows. Have you ever tried Kubuntu? Or MATE, Cinnamon, Xfce flavours? I personally find KDE Plasma 5 the best DE ever, period - that is, once you invest those few minutes customizing it / fixing its few oddities here and there. Why don't you try it out?

Ask HN: How do you set prices?
I'm helping a friend's startup figure out pricing for their products. What are some tools/services that you use to do this? Are there any pricing analytics platforms that you'd recommend?

I can't find anything that wasn't enterprise focused ("Call for pricing!"). Are there any services that your company uses that you're happy with? Ideally, it would help calculate common metrics & make suggestions for pricing experiments (& help run them!).
I also really wish there was a useful way to turn AMP off - it very much interferes with my browsing habits.

Why it can't just be a user option to disable it, I've no idea.

In which case, you are no worse off for choosing not to do business with them than you would be if they did not exist.

Pharmaceutical companies often have monopolies because of patents - but then, you're back to a government intervention again.

Also note that I said "limiting the impact", because it's possible for a third party to impact you without your entering into a voluntary contract with them. For instance: if there is a river running through your property, if someone upstream diverts the river that is going to reduce the value of your property. If you were using that river to power something that enables you to fulfill a pre-existing contract then the common law concept of "tortious interference" comes into play.

More than once I've been in a meeting where someone said "But competitor A spent 1 Billion dollars building that". And I would quip back "And now we know it can be built and it won't take a billion dollars to do it".

I agree, the real value is know something is possible from there all things related make more sense and many decisions can be made based on that one fact.
This is hilarious. Only in the bizarre world we live in could a half billion sale be spun out into a failure to get a billion. Would a billion have satisfied the author or would it have then needed to be two?

I think that the quality of intake of information is somewhat different when it comes to projected light vs reflected light. I think that with dyslexia printed words are slightly easier because it's easier to see the edge of the ink (so you can see the shape better), on a screen it's much harder to see the shapes in the letters. The dyslexia font thing helps a little but it's kinda gimmicky I think.¯\_(ツ)_/¯

> I'm sure the billions of deeply religious people would cope with literal proof that we're not a privileged and special "creation".

Muslim scholars have considered the possibility of life in the heavens as far back as the Middle Ages. Companions of the Prophet openly considered the possibility of religious beings in the heavens. It was recorded of Ibn-e-Abbas that "He even went so far as to say that they may have a Prophet like Muhammad (pbuh), a Adam like our Adam, a Noah, like our Noah, an Ibrahim like our Ibrahim, and a Jesus like our Jesus."

The Roman Catholic Church has also officially accepted that there may be intelligent aliens. So that covers a pretty large chunk of the world's religious believers already explicitly ok with it.
My parents run a business making telescope mirrors, and I grew up around this exact process. Measurement is the biggest difference between this and what they do. Take a look at https://en.wikipedia.org/wiki/Interferometry#Engineering_and... if you want to know more about how it's done in industry.

The best metaphor I got from them about how precise a shape they make in glass is that if you took a typical 1 meter mirror and scaled it up to the size of the United States, the biggest deformity from a perfect curve would be less than you are tall - far less than your ability to perceive.

The other thing that was impressed me is that up until recently, the last stage of high-precision mirror making was literally done by hand. My dad would literally rub on a mirror with very, very fine grit to take out bumps on the order of microns. Recently, they've switched to machines in that last step to make it faster and more accurate, but for many applications the traditional way worked just fine.
And in this case, the reality is the ternary operator is just a pretty bad syntax. Most teachers generally tell you to stay away from them and a lot of style guides do too.

Python tried to make it more english-like just like many other of it's syntax (using and/or/not instead of && || !) and in this case it feels strange to experienced programmers who are not used to it. That being said, if you show this and javascript one to someone who's new to programming, they'll for sure understand the Python one better.

Still, again that's where style guides come in. I've been coding Python for years and rarely ever used the ternary.
agreed.

I think the OP needs to break the problem down into 1) access from bots that identify themselves (e.g. googlebot, bingbot, etc) 2) access from bots that masquerade as humans and 3) activity that is from humans.

#1 should be trivial by looking at the user-agents.
#2 and #3 could utilise machine learning to categorise the behaviour of the connecting party, etc

It's not particularly clear why the OP wants to detect bots... I suspect it's to get a clearer signal of what assets are being accessed by humans.
Hi, alvil - 420ms does not sound that bad.

Checking some of my sites I see:

- values ranging vom 320 - 410 for a bunch of German speaking sites hosted in Europe

- and values of 221 and 240 for my two English speaking sites hosted in America (via firebase - on googles own infrastructure)

So if you are concerned with your crawl budget, I think you better focus on things like:

- On-site duplicate content

- Soft error pages

- and Low quality and spam content

Plus you could also get some high quality backlinks.

And please be aware that the crawl frequency does not directly influence your rankings. So, as long as your do not really have a big problem regarding your crawl budget, you may spend your time wiser if you focus on other metrics.

PS: You may already know the tools, but others could be interested:

> I've also heard that code coverage is a terrible metric and can cause bad unit test practices, trying to cover all lines of codes instead of trying to test for specific behaviors. ... (quality of the unit tests might be questionable sometimes as we aren't testing for all behaviors only ensuring all code is covered) ...

Ugh, code coverage is _not_ a metric. Tell your team and your managers: "A high code coverage number is not the end goal; working code is the end goal." Code coverage simply tells you where you did and (more importantly did _not_) check for problems; the point is to consciously examine the code paths not covered and decide what unit tests are needed there, if any. It's perfectly fine for to say "This particular code does not need to be covered." or "This code path isn't practical to validate except in integration testing, therefore we'll forego a unit test and notify the QA team.", as long as the decision is reviewed and approved the same as one would do code review.

The grit only works where it supports the tool. So as long as you rotate frequently it will just hit new 'high' spots while not affecting the low spots at all. By hitting the interior more often than the edge that's where you'll go deepest, it's more statistics than actual aiming for a some high spot or difference. The tool-on-top or mirror-on-top swap can help to adjust if you've gone too deep by favoring supporting the tool at the edge or supporting the tool in the center causing greater amounts of material being taken away at the edge.

Lots of simple processes can cause nearly perfect geometrical shapes to appear: bounce steel blocks on a vibrating drum for a while (and against each other) and you end up with steel balls that rival ball-bearings in roundness (but not in precision, they will be all kinds of sizes).
