This categorically doesn't fit my experience here in Boston. The overwhelming majority of the people I know professionally are eager to help however they can.

I would caveat that with the note that there is rather less appreciation of bullshitters, so startups with a lot of wank to them might have a harder time being taken seriously. But if you're serious, and you're nice, people will absolutely fall all over themselves to do you a solid.
> You can picture how you’ll look and feel, the money in your bank account, the respect of your friends and peers.

This is visualizing rewards rather than the thing itself. In contrast, visualizing the product you want, or people getting it (i.e the business operation you want) is inspiring.

The difference is conceiving of yourself as a producer or as a consumer (of rewards).
And because it's often the only option. Here's a question for you, which one happened first? A) someone packaged a good in plastic or B) someone bought a good packaged in plastic?
No the article is saying don't ever waste time fantasizing because it's the same as writing new features in code that no one will use. It specifically calls out things like buying workout clothes before you work out, or getting a new journal before you start journaling.

Liz Warren: I'll Smash Up Amazon, Google, Facebook – If Elected to White House
I enjoy Silicon Valley obituaries. I've read them every time some bubble bursts, whether it was the video game bubble, the integrated circuit bubble, the dot-com bubble, or the social media bubble.

What the authors usually miss is that the things they call out as killing the Bay Area (home prices, job shifting, taxation, Etc.) have been true for at least the last 60 years. What they miss are the things that power the engine.

Those things are an at will work force, with legislative protection against non-competes, combined with wealth sharing/creation that is unlike any other place in the world.

There are more IPOs coming out this year, Lyft, Uber, and others. And already the real estate folks have said "prepare for the shock of higher prices." That is because there will likely be thousands of millionaires minted over the course of the year. And while that wealth will be distributed unevenly, some will be lucky, and others will not, once again there will be a refreshing of the 'who got rich with some big event' sorts of stories and people will "know" someone who got rich. I got to experience that when Sun went public, lots of people I knew as co-workers were now much much wealthier than I was, they were buying houses in Palo Alto and Saratoga and I thinking about private school for their kids. Sometimes, or or the other of a married pair dropped out of the workforce. And with that wealth people left the companies where they made their money and went to other companies to grow them. Some of them got to experience that IPO burst, two, three, and even four times.

You get groups of people who "self fund" their adventure/idea and work for free on some new topic. That is hard to do if you don't already have independently wealthy engineers to start with.

Think for a moment if your city was full of people in their 30's and 40's whose lifestyle and needs was fully funded by their existing wealth. Do they sit around and sip drinks on the porch? Not here they don't. They get together and start building stuff. Sometimes small things, sometimes big things. And when they do, there is no shortage of capital companies that are willing to augment their efforts in exchange for a piece of the pie. And some times that explodes again into another pile of wealth.

It is certainly a pretty unique place to hang out. And I expect that is part of why it is so hard to "replicate."
For more on the history of the telegraph, I recommend The Victorian Internet by Tom Standage, which also covers in detail the laying of the first trans-Atlantic cables. Fascinating stuff.
Hi. Thanks for this.

Historically, there weren't recursive procedures in Cobol and no concept of new(). Instead all the data was statically initialized at application start. The compiler did the storage allocation.
One thing I have thinking about recently is that there is a class of hostile behaviors which only seem to manifest online.

This is the stuff that people usually don't have the balls to say in the real world -- only when they're shielded by a computer screen.

For instance last night a friend of mine posted a photo on Facebook of the two of us being out for a drink.

A woman who I have worked with in the past immediately messaged me on Facebook and told me I looked fat in the photo. (I didn't, and I'm not.)

Wtf? I'm sure she never would have had the guts to say that in person.

I think a lot of the worst preachy PC behavior policing, like telling people it's insensitive to wish people a Merry Christmas, happens mostly online or in echo chambers. The majority of people live out their lives being reasonably restrained and trying to get along with other people, then on the Internet they turn into a dick.
This seems like a really fine distinction, but it's more of an unbounded tape rather than an infinite tape. The tape can only reach infinite length after infinite time.
Again I think you're overplaying this. Most of my network has never worked with me and likely would never work for me. But I don't have a particularly hard time getting in touch with anybody I'd like to.

Regardless of whether or not it's useful, it's substantially plagiarized from another source. You don't have an inline citation or visual indication that many of the figures are copied from another article on the topic. The same goes for copying paragraphs with extremely minimal modifications.

Slightly changing sentence structure is not paraphrasing or stating in your own words. Pointing a reader to an article for further reading is not the same as a citation.

To put it bluntly, your arrangement of the material, substantial paragraphs, and a significant number of your figures/graphics are copied from elsewhere without citation.

General aviation aircraft can be stalled easily. Stalling a commercial airliner takes much more effort, which is why it's so shocking when it actually happens.
Hookah smoke has almost no nicotine since it’s filtered through water, but hookah can still be addictive. That’s because tobacco also contains addictive MAOIs in addition to the more well-known nicotine. E-cigs don’t have MAOIs, only nicotine, which makes them easier to quit.
Hm, I think I understand. So you could save the entire dataset up to snapshot x, then for x+1 you would save just a diff. Might have to play around with this. I currently use ZFS snapshots to protect against accidental data loss and I have daily backups off site but these are managed independently. This might make my life easier.

Using terms like "the cloud" and with everything bring wireless definitely doesnt help with people's misconceptions.

Introduction to the Docker Life Cycle
My family (wife and kids) and I have a scheduled flight on a Southwest 737 MAX this week. I'm worried about whether there's an unacceptable risk involved in flying on a 737 MAX because of this morning's crash (and last year's Lion Air crash).

After a bit of googling, I found this article from November 2018: https://theaircurrent.com/aviation-safety/southwest-airlines... Apparently, Southwest has been updating glass cockpits in its 737 MAX fleet to include extra indicators to mitigate factors that led to the 2018 Lion Air crash, like an on-screen AOA indicator and a warning light to indicate when AOA sensors don't agree. (I do wish they had gone far enough to disable the MCAS system when one AOA sensor indicates high AOA and the two sensors disagree by more than 2x their individual tolerance.)

That mitigates our risk in the chance that the crash was caused by the same factors that led to the 2018 Lion Air crash, but I'm still nervous as the cause of this morning's crash is unknown.
It depends on who died.
Ask HN: Often have you had to re-write a legacy front end application
How often have you needed to modernize a legacy frontend application and re-build them using a more modern technology/framework like React/Angular etc.?

At my current job, I have to migrate a JQuery dashboard to React. I was wondering what other people's experience has been in this regard.

What were some of the pitfalls that I should look out for?

If you ever had to do it, what was the most painful part of this migration?
But that doesn’t make sense. The reason we have prop 13 is because someone 30 years ago bought a property for a couple hundred thousand dollars and by the time they pay off the mortgage, it’s worth a few million dollars but they are retirees and can’t pay the property tax.

If prop 13 is repealed, older Californians should have to move out of state. Remember..no one makes money unless they SELL the property.

However there is room for reform with : 1. Investment property 2. second homes 3. Foreign investments in CA properties 4. Inheritance of property and tax breaks on that..5. Prop 13 repealed for commercial properties.

A retiree shouldn’t be penalized for their primary home after paying it off for 30 something years and when they are on fixed retirement incomes.
Given the Zipf distribution, I wonder if just a small LRU cache per thread might not be a terrible thing?

Juggling caches on databases is a challenging thing, and there has been some back-and-forth on best practices. MySQL for the longest time shipped with a query cache. As of MySQL 5.7.20 it was deprecated, and has now been removed in MySQL 8, largely because it was as likely to hurt you badly as help you, particularly with correctly sized InnoDB buffering.
the surface normals don't change when the mask rotates from the front to the back so the lighting appears to "change direction". I think looking at the edges gives you more cues to see that the mask is rotating vs only having the reversing lighting cues in the center

Jeez, the comments here. I feel compelled to point out that the very first line of the linked article is

>[Epistemic status: So, so speculative. Don’t take any of this seriously until it’s replicated and endorsed by other people.]

There's a difference between poorly supported and wrong, and the whole point of having a blog (as opposed to writing papers) is to throw out half-baked ideas and observations that inspire rigorous action.
For what it's worth, I had the same experience. Vaped for a year - the first few months I switched between vaping and real cigarettes, then vaping only. Went down a few levels until I got to 3mg liquid. Found 0mg unsatisfying, so I took the plunge and threw my vaping gear away - cold turkey. It was bizarrely easy. I've tried and failed numerous times and it was just easy. Over two years later and I haven't looked back. I haven't been the slightest bit tempted to smoke or vape and I know I never will - it's like a switch has been flipped in my head. I'm free!

This isn't everyone's experience but I think it's common enough to not just write off as propaganda. I can't prove I'm not some socketpuppet account but this felt real to me.
And how do they verify every single signature on every absentee envelope?

I cite them at the end. The idea was to summarize all the articles into one. I will add a note to the self-attention section - that is the one that I used from Jay's blog. My idea was to summarize all the content from these posts and videos that are referenced at the end into one blog post. I hope it was useful for some people
I disagree - it’s not “a useless exercise”, because it’s not presenting itself as a rigorous study. It just makes you think there could be something to it.
OBS is so good, Fedora (my distro of choice) has a clone of it called Copr: https://copr.fedorainfracloud.org/
>Inside the ship, workers spool the cable into cavernous tanks. One person walks the cable swiftly in a circle, as if laying out a massive garden hose, while others lie down to hold it in place to ensure it doesn’t snag or knot. Even with teams working around the clock, it takes about four weeks before the ship is loaded up with enough cable to hit the open sea.

How is that not automated? I cant believe that companies would rely on humans doing a boring and repetitive task without error for weeks on end when a single error could cause double digit percentage of time at port. Is this is just such an uncommon task that automating this wasnt worth the time saved at port?

edit: Even in the picture in the article you can see a single worker has removed their shoe covers that all the other employees are wearing[1]. Doesnt that degrade the cable right there?

Hopefully 3d street view. You'd want that data for good AR overlays, too.
I agree with you. The FAA obviously knows that there are issues with MCAS, since it's been working with Boeing on finalizing a software update that fixes some of them for months. Grounding the fleet at least until that software update can be deployed seems prudent the moment there's objective reasoning to suspect MCAS was at play in this crash too. (And I think we might already be there.)
> Why? For internal servers within the company you can run your own PKI and CA and use an internal cert, giving you much more flexibility and control over things than just using a wildcart cert and internal DNS server would, without much increase in effort.

Running an internal CA those days terrifies me, its a hell of a responsibility to keep that secure. People check medical records, financial data, and god knows what else on their work devices, and if your CA is compromised that can all be eavesdropped on. Either by an attacker or disgruntled insider. No thanks.
Very clean design. Thanks.

I got my son's French horn overhauled by Dan. He is one of these inexplicably dedicated craftsmen in a very offbeat art--the kind the world would be poorer without.

This is phrased as if it's supposed to be damning, and I'm not sure why. Both companies have been less than supportive of moves to determine if their practices and products are safe. As a business decision: yes, sound, but unfortunately, it's conceivable that their interests could encroach on what's necessary for the public good. Considering the breadth of their holdings and influence, it's important to be vigilant for even accidental missteps on their part.
It always makes me chuckle to see a work of fiction set in modern San Francisco that treats it like a normal city where normal people live. The NBC show “About a Boy” is a perfect example [0]. It’s hilarious to see just how out of touch most Americans are with what this city has become. San Francisco may have been an actual city in the past, but it’s just a filthy office park at this point.

The brain is a biological machine, it follows the laws of physics. There isn't any part of known physics that prevents us from simulating any number of atoms using a suitibly powerful computer.

A small aside, even simulating a small collection of quantum particles fully is enormously taxing with current computers and adding more particles increases complexity beyond just a linear increase. But this is a mathematical exercise.

Now, it's possible that the human brain depends on some law of physics that is not computable (possible to simulate on a computer), but given the level of study that had gone into neurons, along with the temperature of the brain vs the energy ranges we've examined with colliders, it seems super unlikely.

If it helps, Turing machines with n-dimensional tapes have been proven equivalent to the basic Turing machine.

Not surprising. Searching travel record is what they do in daily operation (applying visa, border control, etc..).
I’ve blown a few minds explaining that the Internet is delivered via light, sent through very long fiber optic cables under the sea.

I thought this was common knowledge until the first time I explained it, and the disbelief... Everyone had a revelation that day.

I always knew about fiber optics, growing up with dial up and dreaming of one day having a fiber connection. But I guess now that everyone is focused on mobile that piece of infrastructure is abstracted from even reasonably tech savvy people.
Zipf is a little idealistic. It is perfect for a quick analysis as the base case that a cache should excel at. Unfortunately LRU doesn't because it can be easily polluted. (examples: https://github.com/ben-manes/caffeine/wiki/Efficiency)

A database will often scan many records which would flush an LRU. Postgres uses small LRU buffer caches in your per-thread model, backed by a larger LRU-like cache. The buffer caches are easily flushed by scans, but protect the shared cache from this noise. That shared cache could probably benefit from a smarter policy and this is an on going topic.
It's not this simple. Failure can be the result of too much planning and research as well as too little. Programmers in particular may be more prone to planning too much rather than doing too much but it's possible to overcorrect. The general advice to try something and move forward when you're stuck in analysis paralysis is useful and often good but it's also true that plenty of people put plenty of time and effort into things that ultimately were a waste of time and could probably have been avoided with a bit more planning or research up front.
