It doesn’t sound like you are mentally modeling cache misses correctly. Any access to any array (dense or holey) that isn’t already in cache will result in a miss. A goal is to minimize misses by taking advantage of locality and prefetching.

Let’s assume you have an array of objects that are small enough that 4 can fit in a cache line.

You take advantage of locality by densely packing them into an array so that you can process 4 adjacent (and aligned) items for the price of only 1 cache miss. The array with holes can reduce your utilization by mixing live and dead data in a single cache line. Worst case would be 1 live item followed by a hole that means the next 3 in the cache line are dead bytes. That cache line only buys you 1 item to process. But, if the hole continues for several more cache lines it’s shouldn’t matter because you should have a means in place to skip all of that dead data and go straight to the next live item.

You take advantage of prefetching by processing your array linearly from start to finish so that the CPU will notice and start fetching cache lines further down the array before you even try to access them. Arrays with holes can mess this up by making your access pattern irregular. If your array is very sparse you will be accessing cache lines without a repeating pattern and the CPU won’t be able to figure out how to help. But, the goal is for your array to be fairly dense (or at least reasonably defragmented) so that you end up accessing long, continuous spans of cache lines that make the prefetcher happy. At a minimum, the goal is to do better than most multilevel/tree-based data structures.

Only for that specific use case. It's true that modern smartphones are worse than old voice phones. But modern smartphones are more like pocket computers, they're just called phones for legacy reasons basically. Personally, I think I can count the number of times one one hand that I've used my phone as a phone in the last month.
In high school I went with my German class to Germany for a 6 week stay with various families. One of my schoolmates bought a bundled food item in an American store prominently labeled “Gift Pack” to present to his family.

The foreign family was a little ... perplexed (or maybe just amused) because in German “Gift Pack” translates to “Poison Pack.”

Hey everyone, I'm really flattered by everyone's interest in the language. I had no expectation of that when I worked on it. I'm happy to try and answer questions, though my memory's a bit fuzzy now. I think the reason for this sudden interest was this self-referential Tweet by Robin Houston which used Sentient to construct a pangram:

>The public did not vote for something specific - they voted for something very vague and ill defined, the little information they were provided was incorrect (e.g. "an extra £350m a week for the NHS")

Well, you never have full information, even if you're the PM and passing a new law.

As for the "an extra £350m a week for the NHS", I'm pretty sure all the sides had their misinformation at the ready, there was so much scaremongering and hyperbole from the remain side as if the world was going to end if exit was voted.

The "dire consequences" of an exit were repeated constantly by established media, politicians, celebrities, EU figureheads, and the public still voted in favor of exit, period...

Given the available information, the public voted what it did. It didn't see the outcome of that vote yet though, and everybody has been stalling it.

IDK that "reading things for fun" is a bad habit. I mean, what do you consider good habits? What IS worthwhile and fun? Why can't "doing something fun but of no benefit to the world at large" not be worthwhile?

Even as someone who loves moral philosophy and everything that comes along with it, I feel like that's a pretty cynical take on reading for fun.

Those are what most of the intelligent anti-vaxxers worry about, except for a few people who object to fetal tissue being used in development, which is not an issue here.

I'm sure some folks will get up in arms about this, but it'll be a huge step forwards in many people's minds, and hopefully will be used as a template in the future.

To clarify: I'm not an anti-vaxxer, but I do think the testing process isn't rigorous enough, and I have seen absolutely awful medically confirmed reactions firsthand, which gives me a slightly different perspective. Vaccines are good, but I want the reaction rate in non-immunocompromised people to be zero

Repair technicians who show up at peoples' homes aren't highly skilled electronics technicians. If they were, they wouldn't be working as appliance repair people and driving to peoples' homes. So those repairs just entail swapping out entire circuit boards or assemblies, because that's all those repair people can handle (and all the repair companies or manufacturers are willing to warranty).

The guy on Ebay is someone with electronics skills who discovered that that particular machine had a very common problem with that board, and offered a service to fix that one thing.

It's too bad that can't be done more. It is done some: smartphone makers frequently will repair their devices, usually by having you ship the phone to a repair center. But an appliance is harder since you still have to have the on-site technician take the machine apart and get the board out for shipping, since you can't rely on consumers to do that. It's too bad consumers aren't smart enough to use a screwdriver and take simple things apart, but that's just how it is.

These are not startup ideas, but activities that people do. A startup-idea might be to find a way to make these activities easier.

To make this list more useful, there should be two additional datapoints: 1. How many people does the activity impact 2. How much does the activity impact each person. The product of these would be the total impact. Sorting by the amount of impact would give the most valuable areas for innovation, and there should already be a plenty of businesses focused on these activities.

You say that but since the 90s there has been a concerted effort to not let federal law enforcement escalate to that point (at least in group situations like this). In small swat team type situations they can be very trigger happy but in an ongoing clash like this the politicians would (and have) hold the cops to a reasonable ROE.

‘Foundational promise’

I love these as a new mgr - new guy shows up, I know nothing of their unique ‘foundational promise’, I have no idea if they can contribute or work well with team, I put some effort in to get them going, then they start sending long (they are always WAY too long) emails about being special cased over 20 people who I’ve known longer and have worked harder for me. I check with HR and a hard pass. I’m not considered humane for failing to give someone I’m paying lots of money to lots of remote work time. And I know what remote work time is like when an employee is visiting family - even though they are “working“ it takes them hours to respond to slack.

I don’t mean to be harsh, but if you look at compensation rates - your manager does get to call the shots at least a little in return for money they are throwing at you.

And yes, if a top performer keeping you is pretty high up on list. 20 reports is too many though - def not a great sign in my book.
Mate, he’s saying that as much as you love your kids, it gets old at some point to have them constantly interrupting your meetings.

Most countries you’re thinking of as counterexamples don’t have an equivalent to Air Force One (= near-complete invulnerability for said dictator) or nuclear submarines with SLBMs (= near-complete invulnerability for said dictator’s hard power.) Nothing a militia does storming US land civil or military infrastructure would matter to a US dictator, any more than it would if a foreign military did so. The US military domestic defence system was designed under the assumption that this is exactly the type of attack a foreign military would try, in fact—convincing US citizens (and members of the US military!) to foment a coup, the way the US foments coups in other countries.

Basically, the US president is in the constant implicit position of being able to hold the entire US hostage from a flying doom fortress† like some kind of supervillain. The only people who can really stop a “crazy president” scenario are people either high up in the Secret Service or the Joint Chiefs of Staff, who would 1. Have the authorization to be in the president’s presence during DEFCON 1, and then 2. Have the personal trust/authority to tell the president’s bodyguards to buzz off for a minute.

† The “doom fortress” part applies more to the subs than to AF1, but if you treat the two as a unit, it works.

I'm a speech science student, not an engineer. So take this with a grain of salt, but here's what I know.

In order to process speech with a computer you need to know two things: what is the source (vocal cords) doing? And what is the filter (vocal tract) doing? And you need to extract those two pieces of information from a single audio signal, and figure out what each is doing independently of the other.

Is a sound voiced or unvoiced? Is it, for example, labial (using the lips) or alveolar(pressing the tongue on alveolar ridge just behind the teeth)? That info is the difference between "t" and "p". You need to know both to figure out what sound someone is making, and you need to put all those sounds together to make words.

Most speech recognition uses one method of processing the audio signal: Mel-frequency cepstral coefficients (MFCC). It's a set of numbers that allows you to figure out what the source and filter are doing independently.

Doing this with multiple (human) speakers is wicked hard, because you are only working with one audio input. That's everybody's voice combined into one vibration traveling through the air and hitting the microphone as a signal.

We use MFCC's because they approximate how humans perceive sound - it goes by the Mel scale, which is not linear like Hz, because that scale divides frequencies according to what the human ear is most sensitive to. And MFCCs seem to work pretty well for single speakers.

So the question for this problem should come from the same place as why we use MFCCs: how do humans do it? I don't100% know the answer, but my guess is we use other cognitive and sensory systems to augment our reception of the sound signal.

On the sensory side, vision is a good example because it's super important in speech processing. Among a sea of signals, humans have an incredible ability to tell what sound someone is making by watching their mouth move and matching it with the sounds we are taking in. Maybe having a model that incorporates visual input of a speaker's face would be one approach to distinguish between different speakers in a group.

Another issue to consider is that humans don't process all the speech happening in a crowded room. We are really good at filtering our attention to the person we are directly listening to. If a speaker could match a voice with a unique set of fundamental frequencies then it would be able to identify which speaker to pay attention to. But I don't think MFCCs tell you that info in very good detail, so now you are looking for another method. Google assistant does this with its "voice match", and that feature does seem to improve how well it recognizes voices. But it has to build a model of your voice beforehand, and it would be nice to make a system that is able to differentiate between speakers "on the fly".

How do you distinguish between individual acts of empathy and "empathy at the scale of another species?"

> And the species that do display empathy at an individual level will also display cruelty.

Sounds like that applies equally to humans. There are cultures where cruelty towards dogs and cats is more common that empathy, and even in places where empathy is more common, individuals can still be cruel.

A "Save the Whales" campaign may seem like empathy towards another species, but it only exists because humans hunted whales so vigorously, and are also in the midsts of ruining their environments, so neither of those sound like examples of true empathy towards another species.

From experience, people who are able to live their lives casually collecting weapons here are also able to live pretty disconnected from the reality of these types of situations. We're long, long past a world where a rag tag band of ideologically enfranchised citizens could oppose the police.

The fantasy of standing up to The Gubment comes from two things:

1) a rambo fantasy. a serious overestimate of your own skills where now YOU are the one in charge

2) a supposition that "if it ever came to that" the military and the police wouldn't actually pull the trigger.

We know this is nonsense from historical analysis. From the other side you can look at how the Vietnamese people defended themselves from invasion and if you really think those conditions exist here then you've never been to, say, arizona where this sort of thinking is prevalent.

Edit: I wanna be clear that i don't think this is a good thing. I wish there was some way citizenry could hold their government to account directly like in the 1700s but I think we live in a different world now. One where people enjoy not having a random street war kick off on a tuesday when they'd rather be at a coffee shop.
In that case, an impartial third party would probably consider that harassment, regardless of your feelings. And it can be harassment even if they didn't intend to harass you/did it unknowingly.

However, you _feeling_ uncomfortable is not enough. If you feel uncomfortable with people eating meat around you, that's your problem and not harassment, because eating meat is reasonable in our society.
