Who wants friends over 30? I like to make friends with young people.

In all seriousness, at 42 I really do prefer to hang out with 20-somethings because they’re fun.
I'm not sure... for me the unfiltered version was annoying but bearable for a bit... but I could see getting driven mad by it after a while. The filtered version was so bad that it almost made me wonder if I'm going to damage my ears, so I stopped listening to it halfway. I was using decent BT headphones so I'm not sure if that makes any difference... it may depend on how decent your speakers are at playing 30-40 Hz.

(Side note: Does BT audio do some kind of lossy compression? Why is it relevant that you mentioned it here?)

I agree with you, kayhi. This is our health, and we want to make it so that everyone in the world not only top-tier athletes are never deficient.

Sure, here's a CDC report: https://www.cdc.gov/nutritionreport/pdf/Nutrition_Book_compl... as well as this secondary study that summarizes some of the findings https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4822995/.

Can we really use SSD for long term storage?
You can do the same by buying stocks on margin.

It does not mean this is a good idea, however.
Affordable Test Drive of Tesla's Autopilot
Yes. But you're totally future-proof now. And you can speed it up a ton if you throw in a single fast SSD as the cache disk.

Then in 4-8 years, when the price/performance works for you, you can throw in all SSDs.

I think that edible insects would be a better protein route than lab-grown meats. It would require a cultural shift in some places, but probably not as large of one as people think. (Lobsters were considered inedible until relatively recently.)

Lab-grown meat seems like an over-engineered solution to a problem that might not be that difficult to solve in simpler, probably-healthier ways.
Justin's previous article was much more helpful on SeriesA strategy & tactics: https://blog.atrium.co/the-founders-guide-to-raising-a-serie...
There are serious efforts to found maths on elementary toposes, which are categories with certain properties. Much the same way that the axioms of ZFC model the properties of sets in terms of the "is element" relation, you can give first order axioms for how the morphisms and objects of an elementary topos behave. Then you may add more axioms to assert that the elementary topos you're talking about is really a category of sets in the sense of ZFC.

If you want to research more about this, I can recommend sheaves in geometry and logic by Maclane and Moerdijk. You can also search for "algebraic set theory" and go from there.

And btw, type theory is essentially the same thing. The axioms are IMO uglier and more ad-hoc, but there are (some proven, some conjectured) equivalence results.
Maybe someone should extract the program flow from the AST to create the compute graph, or create a restricted language that facilitate that. It seems in TF or PyTorch the syntactic sugar is infective at some point and you have to use the explicit API.
Your implicit assumption is that the hum is caused by something electrical; i.e. not a diesel engine or some natural cause.
Your assumption that the two are always mutually exclusive doesn't seem justified to me.
> In the tour it states, "We've seen that when a new module must be added to a build to resolve a new import, vgo takes the latest one." which means that the newest Rails would be used and set in your `go.mod` file.

That works for adding a new dependency. But, as I understand it, if I decide to upgrade my dependency on foo by changing its already-present version in my app's module file, this does not upgrade any of the transitive dependencies that foo has. Instead, it selects the lowest versions of all of those transitive dependencies even though my goal with foo itself is to increase its version.

So now I have to reason about sometimes it picks the latest version and sometimes it doesn't, depending on the kind of change I'm making.
You're using monads whenever you code in any imperative language. The "bind" pattern is simply so pervasive that you don't even recognize that it's there, but any time you use information obtained through one side-effect as part of another side-effect, that's a monad. That trivial read-a-name-and-print-a-greeting program which frequently shows up on the first day of Intro to Programming? Yep, that's using a monad.

The difference with functional programming is that you can choose not to use monads, and IO, and other powerful abstractions which are baked in so pervasively into other languages. This enables more powerful static analysis and code reuse, but it also means that you need to be aware of what you're giving up in the process, such as the ability to choose effects at runtime based on the results of prior effects. People who have been using monads throughout their entire programming career are thus suddenly faced with trying to understand what a monad actually is and what sets it apart from non-monadic code. This leads to people writing tutorials and papers and blog posts, which causes people to think it's some super-complex concept accessible only to genius mathematicians, which leads to more tutorials...

The neat thing is, once you've begun to see the pattern, it turns out to be useful in other areas besides sequencing I/O effects; non-determinism, coroutines, generators, parsers, and so on. Most languages make sequencing I/O effects so easy you don't even notice it's happening, but other monadic patterns, lacking built-in syntax, are far more unwieldy. Haskell puts them all on the same footing via the Monad typeclass and do-notation.

I think this could work to limit sales, and I'm actually okay with private citizens using their leverage to not support something, and I think it could help with harm reduction.

We've been doing it with cannabis for so long, it has very little likelihood of political blowback.

I could see this being used and tweaked for a variety of ways.
For instance, those 1-2% shops that will still. Maybe we give them an out where they have a huge merchant fee for each of those weapons sold, limiting desirability for those weapons, and if the bank wanted to be really good, use those funds to work on gun legislation or support groups for victims.
A fieldstrength meter and some wire snips should do the job.

not uncoincidentally, these make for great transitions to a screenplay. Leonard's screen adaptations have been, in the aggregate, very successful.
These write-ups look really useful. There are many out there but they either tend to be too verbose, or cover too small an area. You cover a bit more end-to-end but in a concise and complete way.

Also, it's great to pick off-the-beaten-path topics: the Phoenix command-line one is one I recently actually had to sort out from bits I found here and there.

Other topics I'd be interested in (if you need some suggestions):

- more advanced Ecto usage such has ways to work around some limitations (e.g. fragment() or execute(SQL) for migrations)
- the whole GenServer thing. How these Erlang/Elixir tasks run in a logical machine seamlessly over the network with high uptimes.
That NYT calculator is awesome, and helped convince me to buy my place. Particularly helpful for seeing how changing interest rate vs down payment affects the overall cost of a mortgage and moves the break even point vs renting.

Hopefully at some point they update their site to take the new tax laws into account (which will make buying less competitive for people in areas with higher cost of living)
Exponential discounting. Immediately after a beep, it's several seconds until the next beep, making it far less important to fix.

We use mongodb shard cluster to support up to 10k simultaneous users for our web application. Without this sharding architecture, no matter how big our sql server is we can't handle that work load.
In a similar, but opposite direction, I've found (in my mid, now late 40's) that I really enjoy the company of my Dad's friends. They have interesting life stories, are brilliant, and I've got a wide enough range of interests that it is easy to find common ground.
This is incorrect. You pay interest/maintenance/insurance/tax costs for this home. Then one must calculate cost to sell the house. The appreciation of the home value simply does not all go toward the increase in your investment. One must also subtract the opportunity cost of the downpayment.
I really want to use this - I run a school student newsletter and would love to be able to see how people are reading it. Unfortunately I'd want to host this on my own server that I already have set up serving the PDFs with some small PHP scripts and Caddy. Any options for this use case?

In practice,it’s hard to get much beyond 3x leverage in the equities market. It’s typical to find 5x, fairly common to get 20x, and possible to get to 33x in the real estate market.
Anecdotal but, I'm 36 and I made the most friends I have ever made in my life in the last two years. From doing the conference/retreat circuit to, surprisingly, the festival circuit (Burning Man, Gratitude Migration, etc.) I've made a lot of close, real, amazing friends
Yup, I have an Odroid X running Ubuntu (I couldn't find a Debian that was set up to run on it). It's my mail server, apache server, has an outward facing SSH server, and acts as a sensor data logger. It's pushed pretty much as far as it will go, for a little system like that, with a fairly high load average at times.

Recently had a power cut that killed the system, but rather than reinstall I poked around for a few hours until I discovered the bootloader's zImage had been corrupted. Copied another over from the original install image, and away it went.

When I find myself a decent job, I'll dedicate a more powerful system to the task, maybe virtualize a few of the servers.

Fun projects, although there are many head-hit-keyboard moments in setting it up.
... says the article written by a guy who sells stocks and bonds for a living.

I wonder if he lives in a rental.
This was something that was discussed recently in one of the Pokemon Go FB Messenger groups I'm in. The group is mostly people in their 30's and 40's, and some of the people don't have any friends outside of the group. The game has basically brought them a network of friends that they didn't have before. And because "raids" (in-game battles of giant Pokemon) require multiple people and for you to physically go somewhere, you end up seeing your Pokemon friends a lot. You may even spend an afternoon driving around town, chasing raid battles. Sometimes it's just saying hello and battling, but other times you strike up a convo, laugh, etc. Lots of people feel the game is dead, or think I'm weird when they find out I still play it, but there's still an active player base, and it's methods of trying to get people (usually anti-social people) out and being social, have definitely hit upon something.
On the YouTube video it definitely does sound like something strong going on underground... but that's probably a very poor method of assessment.
No, you can’t. The vast majority of analysis cannot usefully be represented in category theory. You can’t express everything in analysis using morphisms and maps.

When you’re working with structures (algebra, geometry, topology, etc), sure, you can construct them in the language of categories. But that’s very far from “all of math”.
Detecting toxic comments with multi-task Deep Learning
How does one eliminate the noise?

One of those sensory deprivation chambers?

Audio insulation?
Disclaimer: I put a big chunk of that paper together.

You ask how it can be guaranteed with "general code". The first thing to remember is that retpoline is not for "general code". Linux, for instance, does not support arbitrary call depth and barely uses recursion.

Also, take a close look at the "Exploit Composition" section of the paper. Those five conditions are much harder to satisfy at 'RET' than they are during the demonstrated Spectre variant 2 exploit points. For instance, a long speculation window (#5) for 'RET' is interesting to generate since it means a stall while waiting on something to come off the stack.
I have worked on several projects that successfully used MongoDB over the past six or seven years now with three different companies. One project had over 5TB of data spread out over a couple of databases with numerous collections each, and no we didn't shard that database. We also didn't have any issues with accessing the data at that size. When I see negative stories around a technology, especially databases/data storage, I personally like to dig in to see if things are as bad as people say. All platforms can have issues (don't get me started on SQL Server and torn pages ;) ). Most of the negative press I've seen around MongoDB was from people not understanding the technology. Sure there were valid issues/bugs and some people might have lost data, but I don't think it was as widespread as some posts would have you believe (except for those running old versions accessible from the internet without proper authentication that is). Also a lot of posts that keep coming up are from several years back. MongoDB has changed a lot over the past couple years, and they continue improving the platform with each release. Bottom line, understand the platform before using it, learn it's strengths and weaknesses and you should have a successful implementation as well.
Just install the debugging microphones all over, collect the data, find the source (if it's real).
Mine won't, I guarantee it. As long as it is just technology it should not be too hard to strike back. It will get more complex when it is both tech and legal, such as 'you shall never touch the radio module of your car for safety reasons' because the data harvester/ad injector uses the same platform as the collision detector and OTA update.

There ought to be a mandatory disclosure of any phone home or online activity engaged in by your car.
On the Security of Walls
How terribly sad.
The article makes it pretty clear that relationships and marriage take the place of friends, especially for men. 30 is also that sort of point where women who haven't had kids already think "uh oh, better soon than never". I can see the downvotes coming already for speaking on behalf of women, but I have more female friends than male ones and the number 30 is universally dreaded for the reason I describe. Well, then there's the looks factor which, take it how you will, but society generally views that age as "the wall". So by that point, you'd better have found your partner in life. If that's one's goal, and it is for most people, are you going to expend your energy finding more friends or are you going to expend it towards finding a "life-long" mate?

I'm nearing 30, and I'd say over 90% of my friends have significant others. Long-term relationships significantly changes a person's behavior; the concept of friendship gradually shifts towards "How can I include my SO in this?" If we go to the movies, it's gotta be a film that he/she is going to like, and they don't like scary movies so that's out of the question now. Maybe your existing friends you've still got around will tolerate this, but new friends aren't going to do everything that your SO wants to do. With my guy friends especially, everything now revolves around what their SO wants to do even when their SO actually permits us to go off and do guy things. I think this happens to most people, though, and I would be no exception if I was in a relationship. As the article states, good luck if you are trying to make friends with another couple. Chances are at least one person in that party isn't really interested in the friendship.

Putting aside that constraint, however, I haven't had that much difficulty making friends at my age. I think a lot of people figure out that most people aren't worth their time, thus friends really don't provide all that much. As long as you've got a couple good friends who have your back even if you haven't talked in months, you're golden. If you're in a relationship with someone, the even less you need the company of others.

People also get dull by the time they're in their 30s. They spent so much time working and relationshipping that they lost a lot of imagination and didn't really expand their horizons as much as their Instagrams would suggest. I'm not saying this is a permanent state, but a doldrum that happens after a person has spent so much time ticking off the boxes of things they're supposed to accomplish. That's what tunnelvision can do to a person. It's definitely possible to get out of it, which is probably why my few real friends are either in their early-to-mid 20s or past 40.
Ok, let's spend $33000 more on them every ear just to torture them by keeping them in the horrible conditions of a prison for the sweet sense of revenge...

> What makes you think there would be more money than what the scammer took?

They probably had something before they have committed the scam and they also might have been getting their fancy salary during the scam too...
It's not the speed, it's the size and power consumption. Big heavy server racks with 1000 watt power supplies don't go well in apartments.
Isn’t this what JITs do?
> Would this have played out the same way if she wasn't running Windows? What if she was using a Chromebook or an Android tablet?

Yes. Well, at least, a fictional narrative with a similar outcome could plausibly be constructed, because "She can't afford a new X so she's using one she got from her mom's ex-boyfriend" is one of the many points at which a low-level exploit could have been introduced (the point where the actual exploit occurs in the story isn't the only one where it could have occurred), and exploits that could have been introduced there with physical access certainly abound for Android, and I would imagine for ChromeOS machines as well.
This article doesn’t consider at all the cost of rental.
I have no idea in US but in London renting an house is quite more expensive than mortgaging one.
And you have to consider the non-insignificant problem of rental going up 5-10%/year while mortgage interest are going quite quickly to zero if you pay the mortgage at the same rate of the rent.
If I listened to this “genius” instead of being almost the sole owner of an house doubled in price in 7 years I would have spent much more than 100k on rental in the same period without having nothing at all at the end.
I can’t really understand what this “journalists” gain in deceiving people in this way..
Yet again, another site with autoplay video.
I've "lost" double digit friends in the last 5 years alone (they are still my friends technically, just don't talk or hang out nearly as often anymore). Looking back I notice that my parents also had a dramatic decline in friends after a certain age so it may be a common thing.

A theory of mine is that big families were once a thing because it was a way to have built in friends well after 30. When you have 5 adult kids and many grand kids I imagine you never feel like you don't have a lot of friends as the large family serves as a proxy for that kind of companionship.

That being said I wonder how social media will impact this. The majority of my ex friends still follow me, and I talk to many of them multiple times a week via group text.
No, the triangulation you would use for a project like this would look for time delay or phase lag between 2 (or more) adjacent microphones.

The sound pressure wave is picked up by one, then some few microseconds later, it appears on the other(s) a few centimeters away.

This is pretty straightforward with ordinary sounds that dominate the signal. You could pick out the wire which was struck in a piano, and even the nodes and harmonics along its length.

It gets more difficult at lower frequencies and with quieter signals, which precisely describes this exact situation.
I did this math at one point for my particular scenario. Housing was not a good investment for me unless I assumed that there would be some sort of outlandish growth in value without course corrections.

That said, there are compelling reasons to own your personal dwelling beyond money.

Why can mobile providers be still so easily social engineered to this day? Seems like calling them and activating a new SIM (i.e. stealing a number) is still quite easy.
Yeah, by 30 you probably have a partner, kids, and a high pressure job that you started after you got the kids (so you've never spent much time socializing with your current peers). You have no energy left for socialising and building/maintaining friendships.
But that's exactly the point. It would rule out a ton of stuff.
