I have one of Wahoo's cadence sensors, which I use with Strava on my phone, and have liked it. I was considering getting one of their heart rate monitors as well. But seeing this casual misuse of GPL and Apache2-licensed software doesn't give me a warm and fuzzy feeling.

As for GPS weirdness mentioned in the article, I'm wondering if there are some shenanigans going on in Android, or if I ran into some GPS jamming or some sort of selective availability? I took a ride along the Illinois side of Mississippi River north of the Quad Cities, and while I was near the Quad Cities nuke plant, my phone's GPS altitude readings were ridiculous - the altitude profile for my ride showed altitudes over 2,000 ft, when there are no such places in Illinois that high, save at the top of some skyscrapers in Chicago. This was consistent on both the outbound and return trips, with the anomaly occurring just south of Albany. Northward, the altitude readings were what they should be (in the ~600-700 ft range).

I tend to "think" in Logo. Often this comes down to shouting "forward" at slow pedestrians but thankfully my family has learned to keep me away from the reptile exhibit at the local zoo (I have been ejected several times).

It's really quite stunning how many people have difficulty thinking of things in terms of birds and turtles.

I am much more than a “klutz”, I have a mild neurological condition that you wouldn’t notice on first glance that affects my balance slightly. I’m always afraid of what would happen if I got stopped by the police. It doesn’t help that my disability also causes an excessive startle reaction (https://rarediseases.org/rare-diseases/hyperekplexia/).

One time I did get stopped by the police, they made me get out of the car and they saw my hand was balled up like I was about to hit him. I didn’t even think that I was showing signs of aggression - my hand is always balled up. Once I noticed the tension increasing, I immediately told him about my condition and my hand.

I am also Black, so I’m extra cautious. Of course, police are suppose to ask if you have a disability,but I’ve never put too much credence in the justice system.

I totally agree. And it seems like Mastodon devs are starting to take the issue seriously. So perhaps there's hope.

Those questions are horrible. They have almost no signal, I interview a ton of people and I ask much much simpler questions, a question that starts easy and can be made more complex is best. I used to ask stupid hard questions and I have matured.
Just be mindful of what you're optimizing for. Like, minimum energy exerted or minimum distance traveled might not be the best choice for a sedentary office worker.

I, too, spend an unreasonable amount of thought on mowing optimization.

GP wasn't asserting that the original comment wasn't an opinion, GP was asserting that the lack of evidence makes the opinion unnecessary (the question was not "Why ..." it was "How ..." and the question did not ask for any tips).

To better demonstrate why this opinion isn't worth a lot without strong evidence, one can imagine almost the same words, but arguing for the exact opposite side and notice how neither argument is more helpful than the other. For example, consider if the original comment read:

Task oriented people actually tend to be better organized and get more things done. The tunnel vision that goal oriented people have prevents them from performing efficiently enough to meet their goals. Try timing a few things and see for yourself. Not thinking about things might save you one or two seconds total. But you spent more time proceeding with an inefficient plan. Just think a little more. You'll find you are faster, and you spend less time repeating the same motions. Actions require effort and energy. Save that for the stuff that really matters.
Off the top of my head... what do you think NLP means? Parsing sentences, understanding the grammar, POS... are not needed here. Named entity recognition would probably be useful... NLP is such a broad term that it's almost useless, IMO.

There are a lot of research papers out there on web page classification. This sounds much like that.

Classification based on keywords sounds like the easiest, most straightforward way - read up on tf-idf [1]

topic models (e.g. LDA) is another approach [2]

[edit] And I forgot: if you're using Python, use spaCy [3]. There are quite a number of Python/Java toolkits out there for NLP type work and I keep using it as the base for a project.

- 48 kHz can be more easily (and more importantly - accurately) resampled to other common sample rates (which tend to be round multiples of 8).

- While 44.1 kHz can theoretically sample the entire range of human hearing there are some practical considerations that give 48 kHz an advantage. That said, there are few reasons to use sample rates above 48 kHz:

https://xiph.org/~xiphmont/demo/neil-young.html

- Most importantly 48 kHz is essentially "the standard" on most operating systems, hardware, hardware drivers, various audio frameworks, codecs, audio applications, audio editors, etc, etc. For example, 48 kHz is the only required sample rate in the Intel High Definition Audio Specification (section 7.3.4.7):

https://www.intel.com/content/dam/www/public/us/en/documents...

Section 2.2 also describes that the timing for the HDA stream format is based on 48 kHz sample rates and other sample rates require some gymnastics (section 5.4.1) to implement.

- Perhaps not surprising to the HN crowd there can be various issues with other sample rates and resampling across different hardware, operating systems, etc:

In 2018 we should be faithfully playing, recording, and transporting audio at 48 kHz. Legacy applications such as the PSTN, CDs, etc will continue to run at their various rates but I can't think of many valid reasons for new applications to use anything other than 48 kHz.
The Linux kernel sets the standard here of not really enforcing the license. Complying is additional cost and companies are not going to do it unless forced to. SoC manufacturers are not going to stop supporting android just because they're forced to release their changes.

We're long past the days where it was questionable if open source would gain traction and everyone had to be deferential. License holders should start setting the standard of enforcing the terms of the license they chose.

Apple never had a high multiple at any point after 2009, when the most profitable product of all time was established and growing.

This is the last 15 years of AAPL against it's P/E NTM

Apple's PE ratio is the highest it has been in 10 years, and before that it still held a lower PE ratio than its competitors.
Sure, lets blame the travel.

You're very kind to Paul Kocher in naming him one of the "best in the world". Maybe he'd just gone to Vegas too when he decided you could get away with abusing RSA decryption to implicitly authenticate the recipient?

In grouping cross protocol attacks like DROWN in as downgrades you undo your own arguement. WireGuard with this unusual definition can become vulnerable to downgrade, bad guys might get your WireGuard v2 private keys by abusing the legacy WireGuard v1 protocol, the deliberate lack of compatibility between the two not withstanding.

Of course the specifics of DROWN can't work against WireGuard, nor against TLS 1.3, but you're insisting this isn't about specifics, it's a general "lesson"
> I don’t see anything in the future that can make Apple’s revenues grow at an above market rate.

I think this comment illustrates why Apple's ratio is so low: because Apple's future growth depends on new products, and new product development is opaque.

Conversely, businesses like Azure and AWS (and Google Cloud presumably) are already well-understood and the growth story there is just straight scaling.
I've gone down the path of minimising my choices to a small good set for a lot of things. I do this for everything from clothes and shoes to managing my money.

Clothes are simple. 10 shirts that are either black or grey. Three shirts that are work branded. close to ten pairs of chinos and jeans (all work appropriate, some kevlar lined for motorbikes) Bulk undies and socks, all patterned so they are easy to pair up. Two pairs of shorts for summer and a pair of sports shorts for sport and the beach. A couple of suits for the odd time I need them (weddings and interviews)

For getting stuff done like cooking or making stuff, I operate with the minimum number of "tools". For actual tools, this means a cordless drill and screwdriver, couple of power tools, a good screwdriver set, a spanner set and a socket set. For the kitchen it means three good knives, the minimum set of kitchen utensils I need to make everything I make regularly, one good pan and two good big tiered pots that I can steam stuff in.

Financially I assign resources as they come in. I split my paycheck into fun money (pub and lunches/dinners out), food money (going to the shops and making stuff myself), savings and bills. All my bills are direct debited and the amount I put in to paying bills is higher than I worked out it would cost me over the course of the year. This means i only ever have to think about how much of the fun money and food money I have when making decisions.

By minimising my options when it comes to making decisions, I minimise my time working through all the options to make them.
Sure the collaboration features are also valuable. It also isn't obvious that they require centralization. One could argue that only a centralizing organization could extract the rents that could underwrite developing those features, but such an argument only goes so far.

I'm not sure why you wouldn't. You're spending a significant chunk of your time at the office. If you are uncomfortable all of that time it's a significant issue.

I mean if your job only allowed you to sit on a small unpadded stool, wouldn't that motivate you to find a new job?
Yes, or even better moderate white noise. Ambient sound will lower the signal to noise ratio between ambient audio and the audio of interest and so essentially render using this to eavesdrop on someone effectively moot.

As an exercise in using tertiary effects to pull in signals you might otherwise be prevented from receiving, well that is pretty cool.
Coin-Operated Capitalism
I have a hybrid system with my closet and Evernote:

The closet was something of a mess—assorted things used with varying frequency. After purging what obviously could go, I bought identical boxes that would fit in the shelves of the closets and labelled them with letters.

I then created an index. Each box got a new note in a dedicated Evernote notebook named according to its label, and in the body of the note I listed its contents.

My closet now had full text search. This made it ridiculously easy to find any random item I might need. I just had to type the name of the thing, and the matching note's name would tell me what box to look in.

Also, when I needed to find something, I always added an "x" on a newline under the thing when I retrieved it. This updated the last modified time of the note. After awhile, the boxes with the oldest last modified times became prime targets for future purging. It also made it very obvious when frequently used items should get dedicated space with quick access.
I wish the author had expanded on migration from one instance to another and what it entails (similar to the questions and responses here).

Another point I would've liked to see is on encryption and privacy — who, other than the people I choose as an audience, can see my Toots (the admins of the instances, someone sniffing the network, etc.).

If these platforms are being sold as "awesome", there need to be more reasons than just "no adverts and no tracking" (the latter claim is not provable without talking about encryption in a little more detail). No ads doesn't mean someone can't sell your information to someone else outside this platform. It's one thing that the owners/maintainers of many instances wouldn't sell information because of their own moral convictions that led them to get out of centralized, single company social networks. But asking to trust on that basis alone is not enough.

I checked out Mastodon quite sometime ago, but stopped using it after one or two Toots. Network effect — not knowing anyone else is a big barrier. On chat platforms, I could at least persuade one or two people I know to use them for direct chats, but these ar harder to deal with when you're looking for people who are not only local but also are working on similar causes as oneself. Like the author says, finding some interesting people on Mastodon and creating new connections could work, but it also depends on one's areas of interest. I personally also find Twitter very noisy (not in the sense of signal to noise ratio, but the amount of content). At least on Facebook I can join certain groups, avoid the news feed, etc. Somehow the topic wise discussion format seems suitable to me than a chat format (without some amount of conversation threading) with many users.
Thinking things through isn't necessarily pessimistic. When I have a contingency plan already in mind, I worry less about the event actually happening.

“Apple still trades like a steel mill going out of business.”

A P/E of 17 is appropriate for a healthy business.

From multpl.com 's historical record, ~1870-present:

S&P 500 PE Ratio
Mean:	15.71
Median:	14.71

Back when AAPL was trading at a P/E of just above 10, I almost bought some, but hesitated because of its risk of exposure to the Chinese government's whims. I still have that concern.

It is incredible to see such a price swing with a market cap this large. 7/17ths of $1T is $412B!.

I worked/lived in France for some time earlier in my career, you can just use ca va. No real need for salut or the et toi. I had this conversation many mornings in the office. Ca is closer to "it goes" than "it is" in this context. Va being the same as in Spanish.

Ca va?

Ca va ca va. Ca va?

Ca va.
As a question it does literally translate to “How’s it going?” and then as a response it’s like “It’s going”, but translating common idioms like this completely literally word-by-word doesn’t really make sense. It’s sort of interesting to think about for the same reason that all idioms are interesting, but it’s not very helpful when it comes to translation.
> I wish the author had expanded on migration from one instance to another and what it entails (similar to the questions and responses here).

Account migration is not a thing yet, and conceptually requires a new namespace for referencing accounts (such as public keys). There is a multi-year-long actively-discussed open issue thread about this problem.

Am I missing something, or does that set consist of Checkers, Chess, and Go so far? (presumably with analogous misc games of comparable complexity)

Discounting the reaction time wins, I'd say the sample size is too limited to generalize to eventual AI behavior in more complex / open-ended games.

Extrapolation was the cause of the last AI winter.
Yes. Right now the AI has more information than the humans.

Not in the US. I've received one or two important letters from the IRS (that is, I unintentionally owed them money) that arrived via regular post. I'm not sure if that speaks to the reliability of the USPS or a lack of imagination on the IRS's part (or maybe the government trusts the government postal service?). Certainly people and businesses do use registered and certified mail, but not everyone.
Saving data from something like google places API?
Usenet was already dead by the time "corporations" like Facebook and Twitter came on the scene.

What killed it was UBB/vBulletin/phpBB web forums. People who ran blogs with some traffic installed them for their community, it was easy for people to just click in and get started, and then you ended up with huge communities like gamefaqs and Something Awful (and car forums, collector's forums, etc etc). These then generated lots of content, which showed up in web search results.

Then web forums in turn got killed by social media (twitter/tumblr/facebook) and reddit and withdrew to a niche.

Well apparently my French is a bit rusty.

"Ça va" translates literally to "it goes".

So the above exchange would literally translate to:

Hello, it goes?
It goes, and you?
It goes.

I guess it's no more banal than answering "how's it going" with "it's going", which isn't that uncommon for people to say. Answering "how's it going" with "not bad, yourself?" isn't really any better either.
