> Color is overrated in a world where most are colorblind.

That's speaking to the value in communication/collaboration.

The sensory experience itself would still have its own qualities even if other people are unable to appreciate them.

I went through a weird period of a few months in college when tones had a... character. I use that term rather than color because for some reason some of them were tied in with associations I had with the sound of people's voices. Not every pitch had this association, but recognizing the character let me identify the pitch.

The utility of this was certainly nothing astounding, but it was interesting to say the least. And it probably wasn't even absolute pitch.

And then, of course, there's the matter of utility that doesn't come from communication. Color vision doesn't just provide a field of aesthetic exploration, it actually lets people distinguish certain things more easily.
All of that is possible and frequently accomplished with relative pitch. I'm sure you don't disagree, but just for the benefit of other readers. Most of transcribing is recognizing intervals and rhythms, which does not require perfect pitch in the slightest. (If transcribing pitches were purely about recognizing pitches, then it would be maddeningly frustrating to transcribe a recording that is slowed down a few cents. But it can be done just as easily by someone with relative pitch, by focusing on intervals, key relations, and contextual memory.)
Great question. We didn't go into too much detail, but we've built a conceptual search index which maps all these disparate items into vectors that are then used for searching, similarity, ranking, etc. Here's a talk by me from a while ago about an earlier version of the system: https://www.youtube.com/watch?v=J4O42EWfHoo&t=5s

We can go more in depth on the current version of our system if you think that'd be interesting!

I'd argue you are giving them too much credit: they aren't thinking it, they are feeling it. All they are aware of is that you seem like a bad 'culture fit'.

I'd also argue it's not a locale thing. It's that companies 'struggling to stay relevant' are hungrier.

Exactly.

Literally any sleep substance taken regularly can be addictive, either physically or psychologically. Even melatonin, which is what your body produces will get less and less effective.

As an aside, melatonin is often sold at dosages insanely higher than recommended. Studied have shown that less than a mg, even low as 0.1mg is the optimal dose for many people, but you can easily find 1, 3, 10mg dosages, which is insane. I was in hong kong, the lowest dosage I could find on shelves was 3mg - way too much.

350 comments and heated discussions, embarrassing anecdotes about tipping (or not tipping) in the US, claims of tips creep from 10% to 20% and from full seated meals to coffee on the go, complaints of moral blackmail and peer pressure. Aren't all these already strong enough indications that the tipping system is bad and doesn't work? Isn't the fact that it doesn't exist almost anywhere else a proof that it's completely unnecessary?

> When, say, G is a prominent pitch class for a while, and then I hear it come back a few minutes later, that lets me understand the structure of the piece better than if I didn't recognize it.

Give me a controlled example where the return of the prominence of pitch class G lets you understand the structure of a section of music.

Controlled example would mean:

* the orchestration used for the G is different at moment A and moment B, OR the piece is for a solo instrument. Otherwise you could be hearing a timbral connection and confusing it for a pitch class connection.

* the G at moment B is in a different octave. Otherwise you could be hearing a pitch connection and confusing it for a pitch class connection. (Esp. if you have perfect pitch.)

* the musical texture at moment A is different from moment B. Otherwise you could just be hearing a textural connection (e.g., big orchestral hit, moment where the woodwinds return, etc.) and confusing it for a pitch class connection.

* it's not a tonal piece of music. Otherwise you could be hearing the same or similar harmonic progression and confusing it with a pitch class connection.

* moment A is melodically dissimilar from moment B. Otherwise you could be hearing a melodic connection and confusing it with a pitch class connection.

I can't think of any musical moments that meet those constraints.
I have converted my team to Jira and Confluence. There is some initial learning curve, but if you select a subset of the features, and train / document how you expect each tool to be used, they will provide a net benefit to your team.

A friend of mine was at a company that was using JIRA, but they had no processes in place and ended up going back to using paper.

I think you really have to establish some simple processes to really get the benefit from these tools.

You can go overboard and try to require people to document every single detail every single day, but I think this is counterproductive. You have to find a balance.

> Here the school districts were partitioned along different brands of computer.

And...what does that have to do with it? My elementary school had a handful of TI-99/4As. Oh, and a single PET. Others, sure, had different systems.

Yes, same here, except the “extremely rare to have”; most, but not all, of the people I knew from middle class backgrounds had at least one computer in the home. (My answer about similar computers was by class, not make and model; I didn't personally know anyone else with a Timex-Sinclair, though after I got a PC some other people I knew that did, too, but mostly several years later; people I knew had C64, TI-99/4 or /4A, Atari, Apple, TRS-80, and possibly some others.)

Sure; if you never write code that contains bugs that your unit tests don't catch, then "git bisect" is probably useless to you.

As for the rest of us mere mortals, we sometimes write code that has bugs without discovering those bugs right away. In a complex system, it might not be easy to observe an incorrect behavior and immediately deduce the root cause. "git bisect" allows you to retroactively track down the commit that introduced a behavior change, even if it was something you didn't originally think to test for.
Ask HN: Where to find hi-res images of earth?
I just discovered how to create dynamic backgrounds for MacOS (https://itnext.io/macos-mojave-dynamic-wallpapers-ii-f8b1e55c82f). The author of that post built a custom background that shows the planet, lit by the sun, relative to the users location. The satellite images come from Himawari-8 though, and show Asia mainly.
Therefore, I wondered whether there are any other sources for satellite imagery like this.

>All of these are explicit design choices, for example a fixed palette is important to give games a "Pico-8" look and also reduce decisions regarding color choice.

Indeed, which is why they won't change, which is why (for me) an alternative like TIC-80 is preferable to waiting around for Pico-8 to become what I wish it were.

The virtual console space is tantalizing, but the culture around it has different tastes from mine. For example,

>I don't like it (or any of the other fantasy console\pico-8 clones) quite as much as Pico-8 because they remove constraints

This is a pretty common sentiment on the Pico-8 boards; I understand there are people looking for a certain aesthetic thrill that comes from working within the constraints to make something unexpectedly cool. And yes, when I have time, I would like to make e.g. a metroidvania that uses individual tiles to encode 4x4 chunks of tiles to allow for a big-ass map. It just so happens that those constraints aren't necessary for, and sometimes are in tension with, the goals of a good first-coding-experience learning environment.

I also totally understand why virtual consoles almost all use BASIC or lua, but (for me, not for my kids) I wish there were an option with static types. The combination of not being able to see much code on the screen at once plus no static type checking is pretty uncomfortable for me.
>Unless there's something broken, a system down, or a critical issue that needs to be fixed yesterday, I got news for you: I ain't staying late either.

All the tech luminaries?

That was never my experience. For example see http://homepage.divms.uiowa.edu/~jones/voting/risks.html for a warning about the insecurity of voting machines before the Bush/Gore recount happened. And even then it was old hat among the knowledgeable. For example there was the Nebraska senatorial election that Chuck Hagel stole in 1996. (He resigned as CEO of ES&S in 1995, and won by a wide margin in 1996 in an election counted by ES&S machines despite being behind by an even wider margin in the polls. The machines did not allow a recount. What do YOU think happened?)

Were lots of people singing about the future? Of course. But lots knew that "put it on a computer" isn't a recipe for accuracy when the people who make the computers have a vested interest in the outcome!

Which claim? Why did we change from per capita to per acre? Seems like an underhanded way for StrongTowns to make a point (I disagree with most of the "StrongTowns" approach as ideologically driven and opposed to the practicalities people prefer). This is the way these goal-driven ideologues muster support. I don't think you can link a source about a specific area or two as refutation of a point about some suburbs, especially when you change from per person to amount of land.

> In short, rural areas and suburbs require way more roads than downtown, and fewer people live there per mile of road to boot. So fewer people are paying taxes to support even more roads.

I know it can read like common sense (I won't ask for a study from you or anything), but it also reads like common sense that a more traveled road requires significantly more maintenance costs. These are just not binary things that you can answer this way.

> I would be very curious to see a study that showed the opposite effect, and how it could be possible.

Opposite effect of which part? Do I really have to provide a study to show some suburbs incur a financially heavier burden due to their neighboring city than vice versa?

NXPowerLite Desktop 8 Serial Key Crack Full Free Download
This is pretty important distinction.
I think it's overly simplistic to group people into those who have perfect pitch and those who don't. Of course, I don't know if the article makes this claim, but I think a lot of people tend to view perfect pitch as a binary ability -- either you have it or you don't. But speaking personally, I have "sort of" perfect pitch (imperfect pitch? semi-perfect pitch?), by which I mean that I can sing and/or recognize the pitch of certain notes from memory, but not any arbitrary note, not under all circumstances, and not instantaneously. If I'm not right on the money, I'm usually at least within a semitone or two. I can do it reliably enough that I'm convinced it's not just a fluke when I get it right, but on the other hand it's not at all "perfect." Moreover, the recognition happens too slowly to be practical in real time; usually it involves audiating part of a song that I know has certain notes, and using them as reference pitches. Perhaps if I dedicated more time to it I could get it more accurate or faster, and maybe even develop proper perfect pitch.

All that being said, while having true perfect pitch would probably open up new ways to appreciate and understand the music I'm listening to, I think that relative pitch is a far more useful skill -- nigh essential for many genres.

That is weird. In general, what I’ve observed with a sizable fraction of older candidates is that a lot tend to be architecture types with weak coding skills. That would be the stereotype I would expect to be going against an experienced engineer, but I'd think that having ICPC champion on your resume would protect against that.

Dehumanization isn't just the tech industry. It isn't even just industry. Our philosophy has dehumanized us.

Yes, the tech industry can be dehumanizing. (So can technology.) Yes, industry can be dehumanizing, as they try to wring every last cent out of you without concern for what it does to you as a human. But I think the problem runs deeper than that. It's basically a question of who we think we are.

As a society, we no longer believe in God. We believe in the physical universe - in matter and the laws of physics. That means that all we can be is matter that obeys the laws of physics. That's all we can be, because there is nothing else.

In particular, we can't have any free will or any ability to make a real choice. Matter that obeys the laws of physics doesn't choose anything - it just obeys the laws of physics. We're just machines made of atoms obeying the laws of quantm electrodynamics, which make up biochemicals obeying the laws of biochemistry, which make up neurons obeying the laws of neurology - and nothing more.

We can't love in the real sense of the word - choosing what's best for the one we love - because we can't choose anything. Even the lesser flavors of love are just a matter of biochemicals and neurons just doing their thing.

There's no real beauty in any objective sense - there's just certain things happen to hit our neurons in a certain way.

For that matter, there's no truth, either, and not just in the postmodern sense. If our brains were built by evolution, they were built to give a good enough answer fast enough. They were not built to find actual truth, even were such a thing to exist.

So in this view, free will, love, beauty, and truth - everything we thought of as making us human - are dead. We're just machines, just like the computers on our desks. As more and more people believe this (and start to act like it), it becomes more and more rare to be treated in a genuinely human way.

Ask HN: Are there any products for embedding group chats on websites?
Looking for a chat product to make a site feel like a meet-up spot for regular users. I'm surprised Facebook or Slack haven't done this yet. A good example of what i'm looking to achieve is https://keyframes.net. I did find this product https://sidecar.gitter.im however Gitter requires users to register/login using Twitter or Github which is a bad limitation.

Im having a hard time deciding on which platform to use for building a live chat community for a hiphop website. Facebook Groups, Slack, Discord, or Telegram seem to be the main options but none can be integrated directly into a website (as far as I know). Creating a WhatsApp group would have been ideal since most of our early members already use it however WhatsApp isn't an option since all members of a group can see each-others phone number which is a privacy issue. Any recommendations/suggestions are welcome and appreciated in advance, thank you!
