In color? No. In monochrome? Mayyybe...

According to Wikipedia, the wet-collodion process was sensitive only to blue and ultraviolet light. The tattoos reflect mainly blue, whereas skin tone has very little blue; this has the effect of lightening the tattoo and darkening the skin, so it's hard to distinguish them in monochrome. But there's likely no wavelength of "red" you can select where the skin reflects the same amount as the blue tattoo - the tattoo will always look darker. Or to put it another way - there's no stage lighting you could come up with that will make blue tattoos look skin colored, let alone while also making skin look skin colored. The best you could do is to use the blue channel only, or even light the scene only with the deepest blue light the camera can pick up (and convert the photo to monochrome).

Generally speaking you can't make things look very different to cameras than the human eye, as they have similar frequency response. Moreover, you can't distort the appearance of objects very much by picking specific narrow frequencies to light them with, or objects would look incredibly strange under narrowband LED lighting (they don't look perfect, but it's not a heavy distortion). Spectral response of objects isn't totally flat, but it's usually not very "spiky" either, so RGB captures a pretty good approximation of the spectral response in most situations.

Interestingly, this question has direct application in the field of holography, where the scene must be lit by RGB laser. You only get 3 wavelengths to work with (and you don't have a huge amount of latitude as to which 3) and the entire rest of the spectrum is discarded, and yet full color holograms usually look impressively accurate.

[edit] I've played around in GIMP a bit, and you can indeed remove most of the tattoo simply by taking the blue channel. You can further reduce it by shifting the response even more towards blue by subtracting the red and green, albeit with increasing amounts of color banding and other aliasing. I'm pretty sure you could decently approximate this effect entirely in software, with the correct coefficients.
NL has a far, far smaller share of North Sea Oil than Norway (and 3 times the population)

The UK has a similar share (actually slightly smaller) with over 10 times the population.
I get a bit annoyed by this sort of post, blanket statements like:

"With our code base, you won’t be able to easily do test driven development or similar practices that the industry seems to love."

Why does the industry seem to love testing? Does the industry love testing? Does this mean you do or don't love testing?

It also feels like they wrote this blog post to show off: we write our c# code as if it was c code because we are better than all of you.

The fact is that every application is different, they chose to use a language that back in 2000's wasn't designed for performance and so they paid the price of using it for performance and didn't want to pay the scale out price.

Is their codebase testable, yes completely. Will adding unit tests to their code destroy their performance? no, there are always ways to make it testable and fast. Maybe in a few years we will see a "We thought testing was impossible but we made it work and also keep our codebase fast".
These languages have similar grammar, because they all have evolved from Old Church Slavonic, but Russian had different path of evolution, where it has gained a lot of Turkic vocabulary among others.

I know Russian on native level and have visited friends in Lviv. Sure it is possible for me with Russian language to understand some things and with what I know it would be very easy to LEARN Ukrainian, but I don't live among Ukrainians, so I can't understand 90% of anything when I am watching something on yt when Urainians start to talk in moiva. I think, that there is a bigger chance for Polish people to understand Ukrainians, that for speakers of Russian.

It looks like your observation applies to Russians, who are already living in Ukraine and have some grasp of Ukrainian.
This is kind of where grand parent's thesis (that the paper is in fact novel and useful) falls down.

I'd be stunned if the concept of integrating an unknown function that needs to be guessed based on measurements taken at irregular points in time hasn't been studied rigorously from a generalized mathematical point of view. What such study would likely do (that a medical treatment would not) is discuss tradeoffs of different approximation methods, probably explore things like error bounds and behaviours with different unknown functions, and selection of the best integration method.

GP is right in that I'm sure it's useful to have a standardized method that allows for comparison between doctors and patients. But I think it's naive to assume that the findings in this paper are mathematically novel, and further, that mathematicians couldn't do a more rigorous job of deducing an accurate 'standard' way of measuring this.
That seems quite insane: "100 million Chinese people might die if we invade Taiwan, but those are acceptable losses."

I suspect the Chinese leadership aren't that crazy, and if Taiwan had nukes, China would not invade.

It wouldn't at all surprise me if human sexuality adapted flexibly to the social environment. Both can be true. Marriage might be a natural and ubiquitous response to the pressures of living in settled relatively highly communities, while flexible relationships might be common in societies of small loosely associated nomadic groups.
The company doesn’t need to put those shares up, it can be any mix of the current shareholders and new stock.
It probably still is, but by all accounts it is rising a lot slower than many people had hoped for.
It's just as toxic as people seeing *ism everywhere. They create an atmosphere of suspicion that is not conducive to free thinking.

Unfortunately in big groups you will have both of those types and HR is not good at managing finer-grained inter-personal issues. Without all of the context it's hard to judge group dynamics.

You can not actually police that sort of thing. Thorium is literally everywhere in the earth core.

You could basically dig hole right next to your fusion reactor and mine Thorium right out of it, expose it to neutrons and create Uranium-233.
I'm in an urban area that perhaps is a bit poorer than some others nearby, yes. The bigger out-of-town supermarkets have better stock but my usual urban Tesco (and to a lesser extent the two Sainsbury's Locals nearby) just don't have that much stock. It changed a lot in Lockdown 1 and hasn't really recovered.

There's no real way to know for sure (unless you work for Google), but if it did affect your ranking Google would be breaking antitrust law. They've gotten in trouble in courts for doing that with other products though so it's still potentially the case, legality aside.

I find anyone using the term “best practices” usually doesn’t understand them.
FWIW the only two apps that my S20 came with that I wish were uninstallable are the Tips app and the Samsung calendar app, and there is a good reason for the latter (if a user managed to delete all calendar apps on Android the OS does not like that at all). They're pretty trivial to hide.

But some people might have to accept the presence of a Facebook shim for installation is such an incredibly mainstream proposition that they are in a vanishingly small minority wanting rid of it.
The other posts are easily handling the resounding "yes" side of things, but I'll add this: add more context!! My recommendation would be to edit the question/post.

Generally speaking, the tech industry is sufficiently deep and wide that anybody with adequate motivation and resources to iterate will eventually find themselves somewhere interesting, for practical and short-to-mid-term definitions of "eventually", and even in a situation where you're diving into the deep end, cold, and with a lifetime of expertise in other fields.

But that iteration process takes time, and it can be unintuitive. The more specific you are about what interests you (where you want to go) and what experience you have (where you've come from), the faster you'll get somewhere personally significant.

Yes, there's definitely an "all about me" element to this (for want of a better way to put it). I feel the positivity and encouragement already present in the thread answers that to some extent.

It's also very true that adding specifics will make the thread less applicable to others, but I say that a) others can just post similar questions, b) tech changes so much these types of threads tend to become irrelevant over time, and c) more specific often correlates with more interesting!

I think this is missing the point. It's to assume good intent when interpreting whether something is racist or sexist, not assume good intent when deciding how to react to racism or sexism.
The Bible is a very interesting book. I cannot hide my preference for such interesting book. I think that you will benefit a lot from reading it. However, there are some characteristics of the Bible that you should have in mind. The Bible is an ancient book written in ancient hebrew, aramaic and greek (ancient greek dialect). So it has a lot of linguistic expressions that you should be careful of. The expressions represent the cultural and linguistic status quo of the epoch that each bible book was written (by the way Bible means collection of small books).
In summary:
- Consider the time and cultural context. Specially on handling the linguistic expressions.
- Take into account the textual context, take a look into parallel texts (some books of the Bible have parallel stories).
- Be open minded and extract good lessons for you from the goods and bad things of the Bible personages.

You can do something like Dr. Donald Knuth that appreciates reading the Bible as he stated in the video:

Good Luck!
It is indeed the best argument for conservative social values.

But we also have xhamster, xvideos, pornhub and so much more. It doesn't make sense to have fake, sterilized characters in one show, and then have fake sexualized characters in another if you care about the effects on society.

At that point it makes more sense to show how sex can be integrated healthily into a normal human life - neither fucking step-sis because she is stuck in a washing machine nor being superbuff and not even looking a women seems the ideal for society.

I'm not entirely on board with the Julia hype train but they certainly got some things right and both the ecosystem and the community are healthy and growing. Julia doesn't need to replace a bunch of other languages immediately to be successful. Implying that the language is dead by using the word post-mortem is just demonstrably false.
I think that's a bit unfair on Amazon. Amazon has a lot of incentives for teams to maintain existing products and their core infrastructure, and Google just seem to completely lack that.

I agree that Julia can't stack up to Python in terms of a data science / statistics domain. But in everything people use MATLAB for, Julia actually has the upside in many of the qualities discussed in the article: Community, Package Ecosystem, annoying licensing bureaucracy etc etc.
> After reading this article, I want to stock up on more food for myself and my five dependents.

You should always have some amount of food reserves. Space allowing, at least a few days of food. Canned and dry goods with long shelf lives - eat the oldest of this first during regular usage and refresh the stock so you don't end up with 5 year old canned goods.

> Is this panic buying?

A little, yes. There's not much risk of long-term food insecurity in the first world (at least not in the US). There are occasionally disasters that affect us short term - think hurricanes, floods, electricity outages, earthquakes, winter storms in Texas. I'd advise being able to get through those.

> Is it OK? Does it hurt other people?

It can hurt others. At the beginning of the pandemic there was a lot of panic buying. Part of that was an overreaction, part profiteerism, part of it was the world being unready to pivot to consumer goods (like with toilet paper). Do it gradually. Don't go out and buy out a canned goods section at your local supermarket.
Thanks! That's the first I've heard what the actual problem was. Reducing pressure instead of increasing would make the controls inherently unstable.

Wrong. I would argue this is the main reason people prefer Leica/Apple over competitors.
They are a large company. 120k employees. If 1% of them have major personality issues you are bound to have at least 1.2k semi-insane/irrational/irresponsible people and dumb things will happen.

Dumb things like this, or Even worse happen in all major companies, but google is a favorite target of the media due to their money/revenue of the company and that media sees tech as a competitor.

At this point I am starting to feel bad about google. They kinda came in/treated this cultural phenomenon with naïveté. Can’t be ‘open to ideas’ when there is a large group inside the company that gets offended about everything
Example: a friend of mine moved to a new country (Central-European capital to large city in Western Europe). At some point he was in the pub with a bunch of colleagues, and he asked one of them who had obvious accent about where they're from (they were a person of color). They asked back 'what do you mean?', and apparently got very offended.

The funny part: for my friend, who also had a strong accent, it was odd (and not very nice) if someone didn't ever ask about where's he from -- because he was obviously an immigrant.

Just telling this story because something that can possibly be interpreted as 'racism' is 'basic niceness/politeness' for someone else. If we're celebrating diversity then let's embrace it properly.

my takeaway: basically python ate the toast and there is fierce competition for OS devs. Ecosystem gravity becomes stronger the more mass it gets.

Keep in mind, there's actual air-gapping, and there's secure enclaves. This specific attack would have no teeth if your Exchange server / OWA endpoint were only accessible from corporate VPN. You don't have to be one of the top-ten biggest corporations to run a global-scale intranet with off-the-shelf VPN servers, and it still greatly reduces your attack surface.
I keep reading here that somehow “energy” gives young people advantage. In my experience, having lots of energy can help or hinder.
Being a good programmer requires patience, mature view of the world and the ability to think critically. Reading articles and coding all day just serves the ego. A very small portion of young people spend time learning the fundamentals and think about consequences.
So, I think you have an advantage!

> The idea that you can have either best practices or performance is a false dichotomy. Testing can be used to help track down performance issues. It can help you write code faster and prevent breakages. It should not slow you down.

It orks the other way too. Benchmarking can show that your bottleneck is virtcalls/boxing where you have used an interface field instead of a static instance to a concrete dependency.
The argument isn't "performance vs. tests" it's really "performance vs modularization". You can always move the tests upwards until you test the whole monolith. This isn't a common tradeoff but I also wouldn't dismiss it as something that never occurs and "best practices" wrt. modularization and unit testing always enables similar performance. It doesn't.
Yup, post 2012, bunch of people saw ‘ the social network’ and decided tech is cool and makes money. Before that, most engineers were in the nerdy side. As the pool has increased, the talent has diluted as well
Rant incoming.

I, for one, appreciate it. This thing on HN where you have to beat around the bush and phrase your sentences objectively and in a general way, when everybody knows that you are just talking about a specific instance, saying things like "if you [x] then someone may respond [y]" when it is clear that someone literally said [x] so you can just say [y] in reply.. All that stuff is incredibly tiring to read IMHO. If you just want to call out someone's bullshit you should be able to do so in a straightforward manner and in a tone that corresponds with "calling out someone's bullshit".

If we could just be a little bit more honest here I think it would be an improvement.
It is. But if your aim is to displace (never mind replace!) an old, established niche, it's a very steep uphill.

Like the OP, I still use a ton of python. And I consider python to be a newcomer in the sci community, still gaining momentum with perhaps a bigger uptick in the recent years.
People have been given money to replace the amount they would've earned, but the work they would've done hasn't happened. All of the goods and services they would've produced no longer exist. The government tried to make up for the fact that large amounts of the real economy were shuttered by printing money, with predictable results.

While you can of course use the space tether as a power generation device, generating small amounts of electrical power in space is easier done by solar panels. The space tether is usually envisaged to be operated the other way around, to convert electrical power from a solar panel into propulsive force. In any case, you aren't really taking power "from the core", it comes from your own kinetic energy.
> All children start off as fetuses and inherit things

Right, but you said "Children exist in the same environment", which is present-tense. If you said "Children existed in the same environment", then it would've come across as you intended.

> I said it wasn't genetic

Source/rationale? That's a rather strong claim.

> even if it is genetic it can still be treated.

Potentially correct, but it doesn't mean it can be treated well given current knowledge. There's lots of genetic problems where our treatments currently suck, and you can't claim to know when/if those treatments will get better for some specific genetic problem.

> People who discuss this in SSC and marginalrevolution comments don't care about this
