Andrew Huang does a good job of explaining harmonics and overtones[0]. You only need to watch until about the 4 minute mark (from the timestamp) to get an explanation of harmonics and what the sonograms represent.
The short of it is that most natural sounds product a root tone plus a varying amount of related tones above it. Our ears hear the root tone, and the other tones above it are what give the sound its uniqueness. That's why a guitar, a clarinet and 3 singers can produce the same note while sounding distinct.
Birds seem to produce a natural sound without a lot of the related tones above it. Their sound is, relatively speaking, much purer than most other natural sounds. That's very unique.
10k out of 2M isn't a good metric, because there will be a long tail of niche, unpopular clone (AKA a student's first to do list app), shovelware or spyware apps that most people will never encounter. If the list of apps is sorted by users, I'm sure the top 50 will have a massive reach.
ESPN, Hulu and Cruncyroll issue thepop up. Consider the reach of those 3 apps alone compared to the bottom 500k.
Late reply, but I was speaking in generalities. HN doesn't quite fit the bill for a general forum that would improve from those tactics. There is a somewhat focused expectation of submissions, and the comments typically need a certain caliber of quality. Forums like this that deviate from those core tenets converge on being a Reddit clone with fewer users and features.
It's natural for users to engage less and less over time. However, holding the community to a certain standard keeps users from outgrowing the submissions and discussions. No one is too old, too mature, or too "smart" for earnest discussion.
Sites like HN tend to plateau unless there are added features to get new sign ups. Full-length profiles, social features like chat, reply notifications and following/subscribing to users are engagement tactics to keep the community engaged with each other. These are site improvements if the goal is to grow beyond the core audience.
For the record, there is a way to highlight changes. An ellipses denotes that material was left out. Brackets denote that something was changed. In either case, the intent should never be to alter what was said. Using yours as an example:
> That was not intended to be read as a literal quote...[It was intended to] paraphrase instead of literally copying words (esp. if there's no good short sequence of words to borrow), but quote marks are still used. I wish we had a better notation for this. I'm sorry to have caused confusion.
Downvoting can also have a snowball effect. If someone disagrees with you, especially in a contested topic where it's opinion or unclear who is correct, downvotes signal other people to also downvote. You can see the effect on Reddit.
Comments that hit -1 can still recover. Comments rarely recover after -3 or so. The only counter is for the commenter to edit and call out readers for frivolous downvoting.
What people don't realize is that the USDA and FDA operate on guidelines such that the most basic cook can follow them. J Kenji Lopez-Alt points this out in his book Food Lab. There are graphs that show that there are safe temperatures for foods below the often quoted temperatures. 165 for chicken is quoted as the minimum safe temperature, but that's actually the instant temperature. Holding chicken at 155 is safe as long as it's done for the recommended amount of time.
The USDA just wants to prevent wide-spread food borne illnesses that are easily preventable. Hence why the small scale experiments where someone eats chicken only cooked to 155 turn out successful all the time.
Note that this isn't to discredit what you're saying. I just wanted to point out that there's more to the guidelines than the parroted parts.
I hate that this dominates the conversation. I tried some stuff with a pi once. It was a nightmare. I fidgeted around with the installation, and after some slight hiccups, I finally get to install the package for my security system.
Errors. A screen full of errors barfed everywhere. I look at the repository for some basic debugging, and without some serious dedicated time, I can't fix the issue.
This is why people don't want to fiddle with a Pi for these things. Time is dedicated to get the system up, but you're not given any kind of guarantee that it will work out of the box.
I think it's less apathy and more that they don't understand the stakes. It's a lot like how laws in the US were written when data collection and processing was a manual task.
Sure, I could tail someone for two weeks, flash their email and SMS data, and flip through publicly available images of them. Or I can get a bunch of digital data points like GPS, wireless APs, and the actual emails and SMS data. Computers and databases make it trivial to sift through this data.
The average person likely doesn't understand how deep digital profiles can go. They think that because they use incognito to look up birthday gifts and porn, everything that's private stays private. What about when screen sharing a work presentation and there's a banner ad for cancer or addiction treatment? What about months of funeral care ads after searching for what to do after a parent or child dies?
People think that advertisers are wasting money since they see ads for the same purchase made a week prior. They'd be devastated if health insurance providers partnered with Visa or a tracking network to extract a "health risk" profile.
You could make the same argument about having an Xbox when Microsoft already deals with computers. Why have a separate console when you can have a PC that does the same and then some?
Nintendo's first party IPs are partially what keeps it alive. Think about it. Mario and Mario Kart have more or less been the same for generations, yet people (including myself) keep coming back for more.
Also, the Wii marked a decided family-friendly focus for Nintendo. Everyone complains about Nintendo's online ecosystem being so abysmal. This is rightfully so. If you look at it from the perspective of a parent with children, it's basically the perfect platform. Aside from their IPs, Nintendo consoles don't offer much for older gamers that Sony and Microsoft does way better. However, Nintendo consoles do get tons of games that are child- and family-oriented.
+1 for Beej. I barely knew C when I enrolled in network programming, so trying to fill my C gaps alongside learning network programming was challenging. Someone recommended Beej. Then it was just a matter of C.
