There's an interesting hatred of meetings by software engineers, and I think it's to far on the hatred spectrum. There's definitely a lot to hate about meetings and they are very poorly run in general. But the argument of "when do you do actual work!" is not a good one. If you run an organization of 200 people, it's a lot more effective for 25 people to spend all of their time making the efficiency of the team, and impact of the team on the business as high as possible, than it is to increase the team size to 225. If those 25 people can, through messy meetings, debates, and emotional outbursts, somehow make 200 ppl twice as effective, that's great!

I think a better framing for meetings is not by looking at the battle, but the war. Individually, yeah it can suck. But the goal is to ensure a large amount of individuals march in the same direction, toward the same goal, and are progressing the business forward. Some amount of work is needed for that.

Let's optimize for maximizing that impact, not how "good" the process feels.
I’ve got a long running bet this is how AGI will be discovered as well. A full disk alert will lead a tired sysadmin to ssh into an old R&D GPU system and be greeted with “Hello, Dave”
It's whatever you need. If you're just running a simple web-app that doesn't need to do much processing, get something small. If you want to run a database and have a lot of IO, you'll need something beefier. There is no single "best" size. Get what fits your needs.
Unfortunately, there are enough of those stories to keep the pipeline full. However, selection bias is the problem. Your neighbor probably doesn't realize or even encounter the (most likely) far more numerous cases of "person out on bail / released early goes back to normal life and things are fine."

Same reason I don't watch prime time news unless I know a particular story will be covered (hapy local event things, basically). Sensational sells, happy normal everyday life far outnumbers all those stories but who watches the nightly news to hear "man woke up, went to get his newspaper, and saw the first bloom of the year - much happier today"?

I know this is FUD but I get spooked by massive returns without anything magnificent or game changing behind them. How much of this is riding the recovery from last year's trade war uncertainty, and how much is this people banking on Apple TV+? Especially with declining iPhone sales and imo, decline in the quality of their products/services, potential regulatory issues depending on the election... that 66% is really spooky.

I've honestly thought I was crazy for thinking that required tests are ridiculous. Thank you for confirming that I'm right in my beliefs.

At least 50% of my last job was writing tests, and the snail's pace of their dev process was the main reason I left.

Anecdote: In high school (2004) I got a CCNA after a year of networking classes. That was pretty useful. Or would have been, had I not been into Linux as a hobby already. I’ve been in IT since then but ended up never touching a switch or router in my entire professional life.
In the bay area, I have hundreds of acquaintances that are burners, hippies, makers, etc. I've been keeping up with these folks for nearly two decades now and would like to continue to do so as they have enriched my life immeasurably. Many of us get together on at least a yearly basis and often do special events together. All the other tools that we would've used to communicate and coordinate with each other have died in favor of facebook.

So, there's one use case.
A few years ago, I began to grow old of working with dataset pre-processing scripts/"libraries" for machine learning and began to create my own sort-of "pipelines." Last year, I stumbled upon `sklearn.compose`, a relatively newer module within the scikit-learn ecosystem.

I have had a lot of success with this module since then, and wanted to share a tutorial I put together which touches on the idea of managing your machine learning dataset creation steps completely via a configuration.
Plus one on the color laser. It hurt having to buy all of that expensive toner, but the robustness, the long interval between toner change, and the quality and speed of printing has made inkjets a false economy. Inkjets produce better photos, but I decided that I would just pay a photo printer when I need prints made (and they are better prints than I could ever make at home anyway).
I disagree. Quality of life with regards to access to a lot of important things has been decreasing dramatically. While the cost of a television has gone down significantly in the last few decades, the things that matter: education, healthcare, housing, have all skyrocketed in price. If Americans seem "entitled" or "arrogant", I imagine its simply because its become much harder access these basic necessities.
In the UK you always get bail by default, without condition.

The exceptions to this are pretty much just murder, manslaughter, sexual assault, and some drug offences.

In short not being bailed is an exception. This is done on the basis you haven’t actually been found guilty of crime yet, thus the state can’t limit your liberties as you’re innocent until proven otherwise.

It would be nice/interesting to have a Netflix appliance locally in the home network which cached content that was expected to be viewed (next episode of a series, suggestions, promoted shows) along with neighborhood peering to keep as much of the traffic along the edge as possible (i'm not sure where ISPs measure bandwidth if you are connected to another node connected to the same local hub).

OCA seems like a great model for static content, but I wonder if it supports live streaming content as well. When I spoke with Limelight several years ago, they had a reasonably nice model for fanning out streams hierarchically so a single feed could be fanned out very widely late at the last mile.

Incredible amount of support from my parents through all childhood years definitely played a part. Also, since my baby years, I've always had a lot of learning stimuli - books, computers, extracurriculars etc. Although our family was fairly poor, me having access to knowledge always has been a #1 spending priority.
Bitcoin is much like cash in that you can choose to opt out of making your money available for fractional reserve.

Why with cash many don't do that, beats me. According to Keynes, people should withdraw their cash when there is no interest to be gained ("liquidity trap"). In practice, people don't, and that makes Bitcoiners crazy: good marketing makes (especially badly informed) people act uneconomically, since they think they are saving, while they are actually investing in an indifferent manner.

Other important aspects of Bitcoin are, that it makes the money supply transparent, and everybody can validate transactions. This is not as simple with cash or gold.

Curious what more experienced engineers/founders think of this:

I feel that one way to solve both the ownership over data problems and minimize server costs is to use some sort of P2P system where all posts, images, videos, etc are hosted locally. This could be through a browser extension when on a computer, within local storage on mobile apps, etc.

When a user pulls up their feed, it would be directly pulling posts from the locally hosted accounts of those they follow, similar to torrenting. With the bulk of data center costs offloaded to P2P, the remaining server costs could run on donations, similar to how Wikipedia does now.

I'm not sure if a social network like this currently exists, or if I'm missing some potential problems with the concept. Thoughts?
That's just how a market economy works. There are limited quantities of every resource. If you don't pay the market rate for the resource, you don't get it.

No training standards, not larger-scale oversight, a lot of "we have always done it like this here", a lot of "I know the DA and the judge because we go to the same BBQs", incentives to contribute to the (very local and therefore very noticeable) general fund through fines and civil forfeiture, the list goes on. Basically a police that is the strongest gang in town rather than a professional and slightly anonymous representation of the law. Which in the end makes it less likely that the law applies the same to all, irrespective of the person.

I think this is totally wrong. Americans of all levels highly value education. Babies are put on wait list for daycare as soon as pregnancy is confirmed. Parents have had their kids move in with distant relatives to be qualified for a better school district. Kids were driven dozens of miles away in the early dawn hours to get equal education. Students are eye deep in debt. Talk to any newly arrived immigrant with kids and they will talk about how education for their kids was a key driver in the move.

These meme has got to stop. Americans value education but our system is failing us in many ways.
Call me crazy but I think it's possible you've missed the point.
> not the VPs, not the CEO

This is the biggest problem where I've seen companies try to do this. The C-level and senior management team make a big fuss about how the company is having too many pointless meetings, they need to be effective, short and have agendas... and usually you can count in hours the time before the one of the exact same senior managers has sent a 2 hour, 20-person invite titled "project catch up" with a blank body.

(You can probably generalise this to many company initiatives, not just the ones about meeting habits.)
I was in gifted programs until high school, whereupon I went to a magnet school that had lots of opportunities for advanced math people (you could take calculus freshman year and not run out of math courses). The schools (both private and public) broke up the students into effectively the "fast" math group and the "slow" math group. And very often, there was the "me" group, where I was working at my own pace and quickly burning through the math books.

As you say, students who have that aptitude for math tend to have a sufficient motivation to do the self-study, especially if the material can be presented as some sort of challenge (how fast can you get through this textbook?).

That's if they can reliably deliver it in the first place. They kept mis-delivering or losing packages so much that I took my $5000/year spend elsewhere.
This. I went to a small rural high school in the MidWest, attended an elite college, and thereafter lived in L.A. and Chicago. Typically, whenever someone talks about 'fly over' country I don't take them seriously. Reality is a lot more banal and unsurprising. People who denigrate fly over country are exactly the same in their inaccurate claims as the people I know from fly over country who denigrate large urban centers.

When I first moved to L.A. I had two different people (on separate occasions at Pan Pacific Park) ask me if I was from the MidWest. I said yes, but asked how they knew. Both responded, "because you're friendly." Doesn't have broader significance, but those encounters always stood out to me.
The EU system is fine with fraud as long as the fraud involved tricking you into approving a charge? That doesn't seem right. So I could sell Rolexes for $50 and nobody could get their $50 back when I send them a toy watch from the Wal-Mart checkout line?
The main difference between a 'social media' forum and a topical forum is that in a topical forum there's some expectation of staying more or less, you know, on topic. There is some functional overlap, but more limited domain.

We come at this from a strange perspective, as we dealt in old maps for the last thirty years or so, mostly paper, but on occasion things on silk, cotton or rayon.

It's an amazing non-proprietary technology, paper. Even things that are water damaged over the centuries, or obscured by foxing (a kind of staining), many times can be reversed and brought back to a clean state(we've worked some near miracles ourselves on some 18th century maps just recently). Without vulnerability to bit-flip, or cosmic rays compromising the data and rendering a work useless and corrupt, paper is lo-tech and easily enduring.

The paper map also enables a comprehensive view of the subject at many different scales, without having to move a cursor, pinch or expand... none of that, your eyes just take in and adjust. The benefit is an understanding of context and relationship. When we do presentations at schools it always interests us that there is a fragmented understanding of how things relate for some students, which almost feels like an artifact of digital cartography. In a digital world the constant zooming in an out, first to find the greater region, and then to reach down into the detail of a street or land feature. The problem is at that tight detailed scale, it's hard to see how it relates to much of its surroundings. You can push around at that detailed level and form some understanding, but it feels abstract, especially for those that don't have the best visual memory. The paper map affords a certain level of pattern recognition at different scales of detail without constant enlarging and reorienting.

We have maps going as far back as the late 15th century with the matrix of the paper being made of nothing more than cotton fiber, not gold or titanium, just simple cotton. When we read of the challenge of preserving the digital world and the technological progress of our species, it does concern us that even the best storage technologies available might reach 100 years or so.

Timothy O'Reilly in a talk a few years ago mentioned the danger of how technology can be lost. He mentioned how the great church, Hagia Sophia was the largest building on earth for about 1000 years, but then there was a long pause before anything came close to its stature again, almost as if the technical understanding of how to build at that scale was lost. In an era where almost everything is developed, distributed and saved in a digital format, perhaps we should print more hard copies, not just for backup purposes, but maybe for the unique perspective that that simple 2 dimensional surface can supply.

Came here to pretty much write these same notes. The fact that you need to know the spectrum of all the minors really limits the usefulness for solving general eigen* problems. But I can imagine that this could make a great starting point for all kinds of approximate calculations/asymptotic analyses.

Regarding the first caveat that you bring up though, whereas the problem statement says you need a Hermitian matrix I think the results should generalize to non-hermitian matrices. In particular take a look at the third proof of the theorem at the end of the article. The only assumption required here is that the eigenvalues are simple (which does not preclude them being complex/coming in complex pairs).

Protip: I had to read the second step in the proof a few times before I could see what was going on. Explicitly what you do here is to (i) multiple from the right by the elementary unit vector e_j (ii) set up the matrix vector inverse using Cramer's rule (iii) notice that this matrix can be permuted to have a block diagonal element equal to the minor M_i with the other block diagonal entry equal to 1 and the corresponding column equal filled with zeros (iv) Write the determinant in the block form, which simplifies to the expression involving M_i by itself then finally (v) multiply by e_j from the left to get scalar equation.

The way other social media platforms have solved this problem is by targeting younger demographics first, those that are making social media accounts for the first time.

For these "greenfield" users, there is no need to convince their friends to leave their existing social media platform, because there is none.

I'm looking for something to build in my spare time. Preferably a website or webapp.
What bugs me about this is reading the comments. Instead reading this news and thinking that when large swathes of the population are doing poorly there must be something wrong with the system, they turn around and just blame people for being stupid and lazy. There are tons of people in this country that grow up poor, in bad neighborhoods, with bad schools, and no hope of going to college and when things don't turn out well for them, we blame them for it. It may come as a shock to people from other countries but in the US school funding is extremely local. If you're from a rich neighborhood, your school has tons of money and resources. If you grow up in a poor neighborhood, some barely have enough money to keep the roof from leaking. And we've all just accepted this as normal and OK. We have the power to change this but we choose not to.

I really hope this effort is successful! I'd sign up myself, except that I don't really find much value in those sorts of services.

But maybe I should sign up anyway, just to help it along...
But the people who are really successful in a field don't find it hard work to do that. They genuinely enjoy it, and find it extremely satisfying to do what the rest of us would consider to be a gruelling schedule.

There's also a cohort of people who are insanely talented in a field but don't really enjoy it that much, and find it hard work. One of my best friends is an incredibly talented artist, but burnt out doing commercial work in his 20's and rarely puts pencil to paper these days. I consider it a criminal waste of talent, but it's his life ;)

Then there's the cohort of people who are a bit talented in the field, but have decided for whatever reason (usually parents) that this is what they'll do with their life, and hard work is how they're going to do it. Watching them beat their heads against the brick wall is horrifying.

In the end, we need to avoid survivor bias. For every person who says "I did this, and you can too!" look for other people who did the same and yet didn't succeed. Learn from them, too.
Maybe I'm an outlier (being a wannabe intellectual), but I feel like for me I honestly don't care too much about the grander scope of stuff as much as the actual individual problems I want to solve.

I like solving problems with concurrency and networking stuff, and typically don't pay much attention to how it affects the rest of the organization. I have some ethical issues with marketing, and worked on the adtech team of a company for two years for this reason.

I suspect this drives virtually any employer who I work with crazy, since they typically try and motivate me by telling me all of the cool stuff my work is going to do.
