The only part of this article that is worth reading is the last paragraph, where the author is unmasked as a spokesman for the realty industry, who clearly have an interest in more high value low cost housing, for which regulation needs to change. It's a pity this sort of rubbish can't come with an appropriate disclaimer at the start.
>As a layman, this sounds very much like Newton's first law: An object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Many equations in physics are simply restatements of other laws showing the same relationship. For instance Coloumb's law for electromagnetic attraction [0], and Newton's law of gravitational attraction [1].

Seems like it changes reality. The presence of a measurement changes the interference pattern for all observers, no?

If the waveform collapse only happened in my reality then if I observed a field, I would expect others to see an interference pattern, even if I only saw a clear field.

If other people can observe an interference pattern while I observe a clear field, then that's a multiverse. That means you need a whole new universe for every observation. Seems like poor compression. Although I guess if it's an append-only store then it works out ok.
I don't think it should take that long - I definitely got much faster with practice.

Having seen many of my more affluent friends going abroad for Uni and just spending their time and parents money on booze and girls, there is a huge element of truth in what OP says. It is a subsidy for the rich and affluent.
While there may be good arguments in favor of limiting migration into a city, there's this little problem called freedom of movement stemming from the Privileges and Immunities Clause of the Constitution [0]. Cities do not get to write immigration policies. It's totally irrelevant that you think an area shouldn't have more people in it. They're coming anyway.

Short of a Constitutional amendment, a city can only decide how to house new residents once they arrive. Do they move into new units alongside existing residents, or do they displace those with lower income? Do the new beds cram illegally into existing bedrooms, or do the buildings get taller?

If blocking housing construction were an effective way of preventing immigration, that would be one thing. Instead we are all suffering crowded conditions and long commutes because you have cause and effect backwards. Housing units don't cause residents, and the absence of housing units doesn't prevent residents! Residents would, absent your intervention, cause housing units.

I've followed n-o-d-e's content for a couple of years. They've consistently made interesting and inspiring content. I'm not as familiar with neondystopia although I have seen their clothing article before. I think OP's idea would work better as a blog perhaps a community blog ala Popehat. There's more demand for content in the cyberpunk scene than people expect.
In my opinion, required military service for 1-2 years post high school (or deferred until after University) can help mitigate it. I don't have any facts to back up my claim but an environment that has guaranteed work, physical fitness requirements and is heavily team based hits a lot of points. While not a perfect solution, I don't see it discussed often.
I enjoyed building object systems in scheme. The closure way is kind of like focusing on the code without worrying to much about the underlying data structure. The object way is worrying about the data structure and the code is secondary.

This was also the very brief time when memory was actually faster than the core, making it possible to contemplate things like large fixed-with instruction encodings, since the main bottleneck with the early CISCs was instruction decoding and not fetch bandwidth; it is unlikely that, had this period not existed, RISC would have developed in the way that it had.

Integrated Circuits and associated lithography based manufacturing techniques rely heavily on quantum mechanics. The transistors and gates wouldn't work if quantum mechanics did not provide an accurate depiction of the physics involved.

This is what I recommend too. If someone declines me politely with a reason like "Sorry I'm busy today, maybe next time." I'll probably wait a week or so and invite them again if I want to eat lunch with them. If they reply with something shorter like "I got something to do, sorry," with a less kind intonation I probably wouldn't invite them again.
I got an Asus flip recently and to be honest, it is a delight. Cheap enough, Crouton, fast enough and just a nice thing. Battery life is now the biggest issue on any device, at least for me, and the only device that solves that is the openpandora (and pyra as well hopefully) so they are my main travel devices, but the Flip when I have the space and after that the x220 for normal days. Which brings me to; X220 is old but long battery life (15-17 hours with the 9 cell & ubuntu with i3) and I can bring a spare battery and besides gaming it is fast for most things I do besides neural nets, but that's all cloud anyway for me. What is more worrying is that they (I have got many of them from a company throwing them away) behave far better than my 2015 macbook pro; overall faster, overall better battery, overall less slowdowns (the coloured wheel of horror on mac).

Yep. I was primarily thinking about friends / family here, thanks for clarifying that they are free.

It ended up being cheaper than using my bank also.
At that point I kind of dodged the question by getting a high-maintenance girlfriend who dragged me through continual crises. Which kept me occupied, at least. I'm not selling this 'get a wife' thing very well, am I? :P

Now, though, I've boiled it down to 'pick a new goal, work towards that goal, achieve (or abandon) goal, repeat'. I was stuck on the idea that there was no 'right' choice, I've now realised that means there's no 'wrong' choice either, so I just do what I find to be most rewarding, which is building useful things.

"Cartesian programming" seems to be, or be nearly indistinguishable from, relational programming; the examples given in the readme for the referenced library amount starts out with a three-relation cross join, adds some computed attributes to the join, and then adds some filtering conditions.
Meaning is simply usage...in the mathematical sense, Von Neumann's definition may be what is technically a zero sum game, but in general political and economic discussions, zero sum game does have a clear and fairly precise meaning.

In general discussion then, a zero sum game is some game or other activity in which resources are not grown or created but simply moved between different parties or re-allocated such that when someone wins, someone else loses.

I would argue that it's EXTREMELY important that we understand that meaning as I think it's the cornerstone of Trump's world-view. He comes from a deal-mentality driven business i.e. you negotiate to your advantage. For most of his real estate purchases, no value was created, his value was simply that he negotiated a better deal. He has negotiated some amazing deals from what I have seen, ridiculously cheap prices for some properties.

The problem with this worldview is that you see the world in terms of winners and losers, not as a dynamic shifting environment. So if you ban coal, for example, then coal miners have lost out...you don't see that they could all and probably do have jobs in solar energy, which incidentally is work that doesn't severely cripple their health. It's a mentality that you can negotiate your way to wealth. While that can work for an individual, it will not work for a country let alone the world!
When I was in Berlin last winter, I noticed a few coffee shops that had strict no-laptop policies at the front but often allowed laptops in back rooms or further away from the entrance. Seemed like a win-win.
Well put. "All or nothing" is poison, and by that standard, Western democracies also fall in the category of "nothing."

Not necessarily, but unless every part of the stack is open, how can you truly be certain? For desktops it's not as big of a deal, since you can monitor the network activity through a router. But for a smartphones it seems like it'd be much harder to detect.

I mean it's this spot on earth where the nightmare reality of total authoritarianism lives today. We can look at it from without, to whatever extent possible, and remind ourselves that every generation earns the freedom that it has. Having something concrete like North Korea is much more powerful than a book like Nineteen Eighty-Four, a work of literature about some hypothetical place.

What's interesting about total authoritarianism is that it never stems from one person but actually depends on a whole large group of people to perpetuate the social order that makes it possible. Authoritarianism is as much a collective phenomenon as the maintaining of free elections in free countries. Once organized in a certain way, people seem to maintain that inertia of organization no matter who or what is served by that mode, interrupted in their organizational mode by revolutions that shift societies from track to track.

Great suggestions -- the fire hydrant is a great exercise.

More simple exercises are one leg squats -- if you use a desk to keep your balance, they're not that difficult to do and a great exercise you can do anywhere. Also, you can drop down and do 5, 10, 20 pushups anywhere. While on the phone you could put it on speakerphone and drop down and try to hold the plank position for the length of the call -- I've seen some Scrum meetings have everyone do the plank (shortens the meeting much more than just standing up).

A few more ideas :-D!

I don't know why the title says from 2010, the story is from 2005, so take the prices with a grain of salt. Even in New Hampshire $2 for a good croissant* is very low.

I have a few close friends who are cafe owners in NH (and when the time is right I will probably open one as a "side project"), and even here, getting a low-volume cafe or a two-person cafe working well, with staff dedicated to preparing food at bad margins is unlikely. Instead focus on coffee coffee coffee or raise your margins until you're happy to sell every item.

I don't think he understands the leeway he has on prices. Imagine the article his competitor (still in business) didn't write. It goes like this: "We doubled the prices of food expecting demand to go down, but it went up!"

Humans, they aren't rational. And the "coffee buyer" breed of human, they are hardly the price-sensitive crowd. At least in New Hampshire, you already lost the price sensitive crowd to Dunkins. Forget them. Sell the amazing $3.50 croissants with pride. The people who crave it will come no matter the price.

* there are no good croissants in New Hampshire.

An opinion I hear often expressed on HN is that JavaScript is a horrible abomination, and native apps are fundamentally superior.

Could one of those folks explain why they think Chromebooks are succeeding so well, if the apps are vastly inferior?
Specifically, here's how that would be done in Postgres:

create table reservation1 (duration tstzrange);
select * from reservation1 where duration && '[2017-04-30, 2017-05-07]';

In a database without range types, it would look like this:

create table reservation2 (start timestamptz, stop timestamptz, check (start <= stop));
select * from reservation2 where '2017-04-30' <= stop and start <= '2017-05-07';

Personally, I don't think range types by themselves are anything special. However, combined with indexes and exclusion constraints, they're really great:

create table reservation1 (duration tsrange, exclude using gist (duration with &&));
insert into reservation1 values ('[2017-04-30, 2017-05-07]'); -- ok
insert into reservation1 values ('[2017-05-10, 2017-05-12]'); -- ok
insert into reservation1 values ('[2017-05-05, 2017-05-08]'); -- error!

Here's the difference indexes made when retrieving all the scheduling conflicts with a fixed interval (500k rows):

No index (start, stop) 123ms
Btree index (start, stop) 29ms
GIST index (duration) 0.2ms

Quite a difference!

> Most developers I know are frequently hounded by recruiters because the demand for senior developers is stupid ridiculous.

Maybe in your bubble. My experience is that very few recruiters are hounding me, because most of them don't know I exist. I don't live or work in a tech hub, I don't work for a famous company, and I haven't published anything. I don't think that's a particularly unusual position to be in.

It's absolutely nothing to do with talent or experience, though.

Are you sure ?

> especially when you're telling people about it under the guise of your engineering expertise.

Paragraph 14 of the board's complaint makes no claim that he was presenting his analysis under the guise of engineering expertise. Paragraph 14 is solely about him publicizing an analysis whose subject matter the board claims regulatory jurisdiction over. The board makes no reference to the manner of presentation being a factor at all, either as an aggravating factor or a prerequisite for the publication to be an offense at all. The board also does not feel the need to cite any context that made the publication qualify as providing a professional service or otherwise qualifying as professional engineering activity under their own rules (but this aspect may end up being another Oxford Comma case), nor do they attempt to provide evidence in support of the claim that doing this kind of work (even in this non-professional context) requires special engineering education, training and experience.

The board is claiming broad authority to punish anyone who gets caught doing the wrong kind of math problem in the state of Oregon without a license, whether or not they call themselves an engineer in the process. The doing of the math problem is in the board's eyes sufficient to make the activity fall under their regulatory domain.

They do not recognize the possibility for anyone lacking one of their licenses to legally do the math in question; there's no amateur category, no exemption for a layman to do preliminary analysis prior to retaining the services of a licensed engineer, no provision for a student to do work of this kind for any purpose without professional supervision from a licensed engineer. If you do the math and show your analysis to anyone in any context, you need a license. So yeah, it's not a stretch to say that they're considering it an offense to do the math without a license.

It seems speculative. How do you know that, should there have been no sanctions, these free enterprise systems would not have been introduced anyway? Or even know that would not have been developed more than they are now?

With so many huge changes both inside and outside DPRK during the past decades, to credit the gradual introduction free market systems to sanctions seems tendentious.
It's ironic that Ditzel went from Berkeley RISC to Bell Labs and helped develop CRISP [1]. This was the invention of the Decoded Instruction Cache which solved the fetch/decode bandwidth problem. You could have a CISC and not have to worry about decode bandwidth. You could have a wide μop and not have to worry about fetch bandwidth.

I wouldn't say it was an active choice, I didn't even known about hikikomori until very recently, but the description fits my lifestyle.

I went to trade school and graduated as a network technician/systems administrator, but I never got a job and then time just went on and suddenly I hadn't left my home for years.

I wrote in my first post, I'm sad I missed out on so many things in my youth, but sometimes I think the reason why I'm sad is because I have been conditioned by social conventions to believe that I should be.

If I had been going to parties in my twenties, according to social conventions, I wouldn't have missed out and should be happy, but what if I should be true to myself?

I have actually never really enjoyed other peoples company and had I been invited to parties, there is a great chance that I would just stand awkwardly in the corner waiting to go home.

I do get extreme enjoyment from programming and doing other computer stuff alone, and I'm able to do it 24/7. Maybe I actually have the most fulfilled life that I could ever have, following my personal preferences, but social conventions are preventing me to acknowledge it?

It's a double-edged sword.

My office is very near Washington Square Park in NYC. When the weather is warm there's almost always a band playing jazz in the park at lunchtime. As often as possible I'll bring a sandwich to the park and just enjoy the moment there, watching people walk by, listening to the music, staring up at the big trees swaying overhead.

Like you, I usually find myself refreshed afterwards, and often wind up walking back to the office excited to tackle something that I'd been dreading when I arrived in the morning.
