Are you working on zedstore? It is one of the postgres developments that I am anticipating the most. cstore_fdw looked pretty cool but it never lived up to the hype and had a lot of not so intuitive limitations. A storage engine built using the new table access APIs seems like the right foundation.

Any word on when you are expecting stability? I'd love to see this in RDS.
I have had this on an open tab for a few weeks now. Looking forward to finding some time to dig in.

Even the fact that all these music services center around playlists is part of the problem. I don't want to spend my life making music playlists - I just want to play music. I don't always want to play an entire album either. What I'm saying is - if I've "added to my library" or I've "loved" a bunch of stuff, it would be so great if there were a convenient way for these services to auto-build playlists or just let me shuffle my whole library.
Yes. If you visit someone's home and connect to their wifi, every app on your phone can record that you are there. They record the other people that are there, too. If one of those people has been reading websites about topic X, the ad networks record a high interest in that topic. It makes sense to advertise X to the people close to that person.
I recall running perl and php on shared hosts in the 90s. Probably not FCGI, but probably close in spirit.
The author describes "believing" in "Good Old School Chicago Economics" by analogy to religious faith. He then says that most learners balk at being told they are made in the image of "homo economicus" (our Lord and Saviour). He is cruel! He is nothing like me, or my family!

If learners can't accept the orthodoxy, if it causes them cognitive dissonance, then where does the problem lie? Is it within the student -- unable to grasp the fundamental Truth revealed in the gospel of "Good Old School Chicago Economics"? Or are they (unconsciously?) rebelling against indoctrination into a death-cult which is worshipping the antisocial, careening towards an apocalypse, and telling them "There Is No Other Way".

I dunno, it's probably because undergrads are dumb.
Yah. Canuck here and find it an odd thing to require for gas of all things. I get it though for cc validation.
There is a point around 200wpm (?) that I think would be very handy to be able to "type" this fast, using shorthand or whatever. This where you can keep up taking notes when talking to someone but also take in the subject matter. Being able to do that all at once and then have those notes to refer to would be very useful.

A lot of time is wasted by not having a record of things.

Maybe "AI" would be just as good as solving this problem though.
> Not everybody does user testing where you sit down with new users and watch them use it.

I'd really like to. Management rarely lets me. When they do, they don't take my advice.
> APCs are purely defensive

Er, no, they aren't. They are mostly offensive, since the point of them is to allow infantry to more effectively conduct offensive maneuvering in the presence of automatic weapons fire rather than being pinned down in static defensive positions.

Military technology is almost never purely defensive.
Did you consider going to work for the large litigation-prone competitor?
This is an extremely important result, which I have seen around before. What are the implications and follow-up research?
It’s acute.
Take a look at air source heat pumps, e.g. Mitsubishi. They are (probably) the future of HVAC. They also make it pretty easy to do a zoned system, e.g. separate control for different parts of the house.
I’d probably drop my Netflix sub before my Spotify sub.
> > And, if I did build a system with a ton of active users, Lambda handles the scaling of that.
> This is a bold claim to make without verifying it.

I mean, Lambda's ability to scale is a well documented thing. It will happily do more if you ask it to.

The real scaling problem is your wallet, because Lambda is damn expensive once you have any somewhat serious compute requirements.
Spotify does that. It suggests custom playlists (e.g. Discover Weekly) based on music you listen to. If you play one of your playlists, it will continue playing similar songs even after you run out.

> There is a building going up in Oakland right now where Factory_OS put out a press release that they had built it in ten days. But they spent 7 years getting approvals, 18 months in site prep,

I'm currently gut remodeling a small house in Oakland. Permitting and regulations are a whopping 3% of the cost.

The land (the existing property) is 50%, and 40% is building costs.

Land costs (addressed via incremental upzoning) and build costs (addressed with more efficient building technology) are the 2 biggest things to address to make housing affordable, not the cost of permits.
Yea dawg this is a horrible take. Most jobs go through recruiters, not chance impressions of CEOs.

This reads like an overly pumped up alpha macho business guru telling his disciples how to "crush it".
This should also be added for Forbes if it isn't.
I think it can be considered a one-time decision based on probability.

In my case, I know I don't expect to call a ride every other day, at most once or twice a month (even less now when bars are closed – but that's an edge situation). I know the approximate cost of a ride, typically €12, surge pricing may go up to twenty. So at the most, I expect calling a ride to cost me €20 a month.

That's less than what resident parking would cost for a car for the same month (a few years ago it was €9 / week). So the ride-sharing wins. I can think about this once and re-evaluate the situation every year. Yes, sometimes I may spend more on rides, sometimes less, but on average it's a cheaper way of getting around. So even though every time I call the ride it's technically a purchase decision in that I can decide not to do it and walk / bike / take the metro (assuming it's still open), it could be argued that I had already decided that in this situation I would call a ride. So no decision fatigue.

Note that driving my own car isn't exactly a "decisionless" process. I have to think where I'll go, whether I'll have easy surface parking (free) or whether I'll have to purchase underground parking. Plus, bonus points for underground parking being paid by the hour, so now I have to make a decision every hour about whether I want to stay out (purchase more parking) or leave.

Also, with regard to the data plan, we don't have those in France (that I know of). My plan has 40 GB and I've got it because it was cheaper than my older 15 GB plan. I know my usage never has me go above 3 to 4 GB. If an unlimited plan was available for a few more euros, that would be a net cost to me, for no practical gain in peace of mind or anything.

I suppose not everybody has a "boring routine-based" life so this approach may not work in each and every situation.
My first C program was also in the Amiga! I taught myself C from those “Abacus” books when I was about 14. I was using Lattice C. Fun times.
I don't know what trouble you ran into. It's not difficult to write a web app in Haskell, nor was it seven years ago. All the major frameworks had been established by then. But at the same time I don't want to dismiss your difficulties. Whatever was going on clearly left a scar.

I will say there's no such thing as a programmer who can't learn Haskell and be productive in it. It's not fundamentally more difficult than any other language. It's just that you have to learn to program more or less from scratch again. That initial learning curve was more work than I'd been through to learn a programming language in 25 years, when I first learned Haskell.

Of course, there's definitely such a thing as a programmer who won't like Haskell even after learning it. It's not for everyone. But neither is perl, or c, or python, or java, or....
I agree; the most exciting use case for a system like this would be that it would functionally (no pun intended) replace the idea of "tab-completion" for typed functional programming languages.
Not really dude, just list your experience and in the interview they will talk about it so you can elaborate on it.
I don't think I would have arrived at the non-shallow project without churning through the shallow ones first.
I'm usually pretty neurotic about getting enough sleep, but if I just won the Nobel Prize I certainly would want to be woken. That's gotta be the moment of a lifetime.
Yea, in the unlikely case I were to be considered for a Nobel prize, I think I'd be ambivalent between being woken up and being inundated with congratulations and requests for comment without being able to confirm.
This is a company doing this, not the government.

By the way, companies _can_ take the easy road and allow absolutely everything. _Nobody_ wants to use such a service though. Visit reddit clone Voat, and see if you want to revisit it again.
Yeah, it has been interesting. I'm glad they are staying safe even if it has affected our income substantially. It isn't the islander's fault the U.S. has been unable to contain the virus for so long. I'm not sure about the other islands, but for Maui person over 5 years old coming to the island needs a negative test within 72 hours or they will need to quarantine for 14 days. They tried to implement this the past couple months, but changed back to the 14 day requirement.

Yes, the quarantine orders were very strict. You could not even go pick up a rental car. You needed a private driver hired. You could not go get groceries. We know of people staying at a hotel that opened the door when a service person knocked to change something. The guest told them they were in quarantine and shut the door. The front desk called within a couple minutes to ask why the door had opened.

The locals we've been in contact with have been making the most of it. They have very much enjoyed having the island to themselves. It is (hopefully) a once in a life time opportunity for them.
This wasn't something your architect discussed with you? They should have, this should be an integral part of how your home is designed and functions.

> I was baffled, bemused even, by the article's premise that anyone rational ever thought serverless was going to take over the software world.

The way people talk about it, I certainly get the impression that a lot of people think that way.

But I agree with you in full otherwise - there is no way that Lambda is going to completely usurp all forms of computing in the cloud.
Symmetric Memes with Opposite Intent
Somehow "4 hours to 15 minutes" sounds way more impressive than 15x speed up, at least to me. From the article, it's unclear how the hashing mechanism you use actually approximates rank at all; most hashes I'm familiar with are essentially one way functions, ideally preserving no information about the input at all. How are you hashing ID's so that unions result in smaller hashes?

Look at the multi-zone minisplit heat pumps from Mitsubishi and Daikin. These systems support room-by-room zoning. They'll do air conditioning in any climate and can be designed to provide heat in conditions down to 5 to 10 degrees below freezing.

If you're in a climate that gets colder than that, get either baseboard heaters, or a zoned boiler system, for backup heat for when the heat pumps can't keep up during cold weather. Which option makes the most sense will depend on how cold it gets and for how long.
In grade 9 a friend and me thought wouldn't it be a great idea to do the office administration class as a means to meet girls, so we did. Class was about 90% female and we learned to type not looking at the keyboard. Now, as a programmer that has been the class that benefitted me the most over the last 20 years.

Since when do you need someones consent to say a thing about them?
> IMO what makes something serverless is that you don't need to provision or manage infrastructure, and also no need to worry about scaling as it will go up and down as needed.

This is why serverless is such a stupid term to begin with, IMO. It's not even an accurate descriptor (the stuff is running on a server _somewhere_), so it really could mean anything.

Something like "cloud functions" to describe Lambda and "managed Kubernetes" for Fargate. Of course, these terms are less sexy, so they'd never catch on.
I think the sentiment you are responding to is the erosion of good jobs. There are tons of new jobs, but for those impacted by this stuff very few of them are good jobs that pay a middle-class income (I know, I don't have a cite, but I'm explaining a sentiment, not a fact - so iono I don't got it).

A contractor in a town where the jobs dried up might work at Lowe's now for example, where they would be kept under 20 hours a week so Lowe's doesn't have to pay benefits, and they could look forward to living in a van off of social security when they retire (source - this is my brother in law at 55 y/o - he has no idea how computers work, and desperately just wants to go back to laying tile like he did for most of his life - lost work - got a job at Lowes a few years back - just laid off actually, due to the virus - he's 100% screwed). There are a lot of these folks floating around, and what has happened to them is absolutely tragic.

Ideally he should re-train in something, but what often winds up happening is that they get sucked into for-profit colleges that encourage them to take out predatory high-interest loans for training that lead to job markets that are either oversaturated, or misrepresented. Then come the payday loans, then come the repossessions.

Ideally those people would just buy a bunch of NoStarch books and become fullstack developers or something, but that's not how people work, unfortunately and we just haven't figured out a good mechanism to help keep those folks on their feet.

The person you're responding to is waaaaaay too angry, and I don't believe you deserve to be on the receiving-end of that, but they may be going through some really rough stuff right now. There's a lot of people who have suddenly found themselves unemployed and homeless and they may very well be in that situation.
Virtualization Challenge IV – QNX 1.2
This is a complicated question because the answer relies heavily on where your house is.

Living in the Pacific Northwest I'm able to get by with no AC but need decent heat. When I lived in California, air conditioning was kind of a must but heat was pretty much an afterthought.

Ideally, engineer your house so you don't need a powerful HVAC system to be comfortable. We have (amazing) insulation so we don't need any air conditioning, but it gets a bit chilly so we are working on installing radiant heat in the floor.
I had a college radio show when Pandora was starting, and had shockingly responsive conversations with Tim W. about up and coming artists he should include.

It was a brief window. Now their catalogue is so full I doubt anyone could add too much value like that.

He sent me a tshirt, which was kind, but what I remember more is how he responded to recommendations. He's a musician and it was obvious he cared deeply about music. To that point of unhealthy obsession that drives some of us to work at record stores and host radio shows, and others to commit to building a transformative service that helps everyone discover new artists they might like.

You can't help but recognize it if you have it.

You might have a different opinion on the economics of it all, or wish the industry could go a different direction. But if you really talk to these people, there's no doubt they do what they do because they love music.
Shameless plug nextmv (YC W20) https://nextmv.io/ is building tooling in the same space in Go and were cloud native / serverless first.

I used optaplanner at a previous gig before working at nextmv — we don’t offer the same type of “choose your own adventure” tooling compared to optaplanner yet, but it’s much more lightweight to get, say, a routing model shipped in to production IMO. (Java shops notwithstanding).
We've been using full Serverless for the past year with Serverless framework little to no issues. Sure, a single server would be a little bit quicker but that is my only major complaint.
It's late, time to relax/focus/read!
It is amazing to me that anyone takes the "permanent" thing seriously. It's as permanent as the current management regime. If they ever decide to change it, it will no longer be "permanent." Statements without penalties have effectively no stickiness.

100% of corporate policies should be viewed as ending with an implicit "for now."

I optimize for escape hatches. Because if everything is on fire I want the ability to be able to bail(fix it).

There's no point in waking up when everything is blowing up if you don't have the access to fix the underlying issue. AWS doesn't actually guarantee 99.9% uptime. What they guarantee is they'll give you some company currency[1] if they can't meet or exceed 99.9% uptime.

Capitalism is a system in which the owners of capital have most (or all) of the power.

So, every part?
Depends so much on your climate.

Heat: the best by far is under floor heating (hot water not electric). Each room will have its own thermostat. There will be no cold spots, it will just feel cozy. No air is being cycled around the room keeping dust down.

Ventilation: indoor pollution is usually many multiples of outdoor. You want a an MVHR (or MEV) system to exchange the air in the house for fresh air with low heat (energy) loss.

AC: You need to move cold air around for this unfortunately. Pumping chilled water through your under floor heating pipes risks condensation in crawl spaces, and even if it doesn’t it simply doesn’t work very well. (Source: I had ‘radiant cooling’ ceiling panels in my last house.) I would look into a mini-duct or ductless AC system so you can control each room individually.

In climates that require heat and cooling, it is far more cost effective to go with a standard HVAC system, unfortunately, as you’ll be putting ducts throughout the house for AC. (Why put a separate system in for heating when you could just move hot air around?) But if you want the best, not cheapest, solution you really want under floor heating.
I work for a high-end custom residential GC and have see a lot of high end HVAC systems.

The new trends are as follows:

HRV (heat recovery ventilators) are pretty in. Basically they are auxiliary units that source outside fresh air or exhaust stale air when there is a heat differential between a specific heating/cooling zone and the outside temps. So if you are in a basement that is cold and the outside is hot it will just bring in outside air instead of turning on the heater.

Radiant floor heating and radiant cooling zones are also in. And run water through Your floors to heat or cool zones. It is one of the most efficient ways to heat a structure and feels good as well.

Geothermal is also pretty in for high-end residences but there is a high first cost to evaluate geothermal potential.

Most of these new technologies are usually coupled with standard split-systems or VRF systems and add additional efficiency (life cycle cost value) over the span of occupancy but have higher first costs .

Lastly— always consider passive heating and cooling strategies they are highest value options (insulation , shading, glazing specs , solar orientation , landscaping , etc.)
Do you think a desire to put more than five minutes into designing the patch means I don't want it fixed, or don't want it fixed quickly?
"All of the platforms are catered to mass audiences anyway and suck for power users."

They are catered to investors. The "mass audience" is just a selling point.

Neither investors nor the web/mobile "entrepreneurs" care whether the "audience" is complaining or not, they just care whether the audience is captured. If the audience cannot "leave", if it is made excessively difficult to do so, if there's no other viable alternatives, that's a positive in the eyes of the investor and hence a first priority of every web/mobile "entrepreneur".


 Why not support these generous "entrepreneurs". They give away so much "for free". Accept all advertising and tracking.
> I posit that nobody in any of these orgs deeply cares about music.

I know people who work for “these orgs” and most (albeit not all) deeply care about music. Some were previously full-time musicians. Many make music as a passion/hobby but never pursued it professionally. Some are ashamed of or uncertain about the impact they’re having on music and the industry. Some seem to genuinely believe they’re helping push music forward. None of them are perfect stewards for music or the music industry, but none are the cold, greedy caricatures you’re imagining. I can only speak for the people I’ve met and they may not be representative, but the bar you set was “nobody” and it’s just not that simple.
And also, hopefully your hvac system will last long enough that you will benefit from your efficient mini splits that 1) are efficient because you didn’t buy the cheapest one, saving you money from an increasing cost electrical rate or expensive PV system and 2) will benefit from a greening electrical system as coal and other dirtier power tech goes away
Because it could be fun? Or is that not HN worthy?
It's a good way to capture user tracking data and be precise in knowing exactly who is doing what on site or mobile app. Hopefully this data stucture can be extended to completely remove every bit of tracking information collected about a user, so that it can comply with GDPR and respect privacy.

Be careful in tracking users, it may fall foul of GDPR and GDPR compliance. If your company is using analytics like this, it will be almost impossible to remove personally identifiable tracking information from website or mobile app platform.

This means it will become a nightmare to remove the user tracking information from every system and system logs. This is one of the reasons most solutions in USA are ill-suited for Europe. Hopefully USA can really start respecting privacy and build systems which keeps privacy on top.

Given most admired companies are built based on invasion of privacy (facebook, google, amazon, netflix), I doubt there is a will to get rid of privacy invading technologies from core. I see some efforts by Apple, but than the larger app eco-system still rely on trading privacy for some free apps or utilities will be hard to go.
