Potentially noob question... but how does having a lambda function per route work with connection pooling for something like Postgres?

Also, does ZEIT have any plans to offer hosted databases like Heroku and others do? That's one the biggest blockers in my mind to trying it out.
"Damming this river will hurt the surrounding ecosystem" and "Damming this river will provide power for thousands of people" are both objective truths. The only way to mediate between them is by discussing non-objective things like how we value fish and the services provided by electricity.

Do we value keeping fish alive more than keeping old people alive via power-hungry air conditioning?

There are millions of similar conundrums, none of which are solvable via appeal to objective truths.

- The first phone with more than 2GB of RAM was the Samsung Note 3 back in 2013 - with 3GB.

- Almost every "flagship" phone since 2015/16 has had 4GB of RAM or more. So if you've seen people using phones on the street, subway, office, etc in the last 3 years, you've seen phones with more than 2GB of RAM.

The old Bird and Lime scooters had 250W motors. The new Skip scooters have 350W (plus suspension which is nice). The skips can get to a walking pace up to ~10% grade, but grind to a halt anywhere near Nob/Russian Hill. You need at least 750W to do the trick.

They also all have just a single break, which makes going down those hills dangerous.

I disagree that joy is superior to pain. They’re both necessary parts of life and one without the other is indistinguishable from oblivion. Plenty of people would disagree about alive/animate versus dead/inanimate and in ways that would probably surprise you. I like mountains, I think they’re certainly more interesting and beautiful than pigeons. As for “murder is bad”, plenty of people disagree vehemently about the definition of murder. Is killing to defend someone else murder? What about killing someone during war time? Those aren’t even close to being settled issues and are absolutely matters of belief that are not provable in any scientific sense.

It's not a community for everybody--we deliberately focus on actionable technical information and training, and tend to skip over more entrepreneurial or marketing stuff ( https://barnacl.es is a sister site that's way better for biz talk).

The culture is ongoing in refinement ( https://lobste.rs/s/oackyq/lobsters_community_standards#c_sy... ) and evolution, reinforced by periodic meta threads where aspects of the site and culture are drug up and commented on and tweaked.

It's probably the most rewarding and healthy tech community I've been involved with in the last decade. :)
Of the scooter companies that have launched in the Bay area, Spin were by far the least technically advanced - the scooters were basically unmodified Xiaomis, to the extent of still having power buttons. Rather than an integrated location and management system, location data came from a off-the-shelf GPS tracker spliced off the battery lines. Since the scooter control board had no cellular link, there was no mechanism for Spin to directly manage the scooters which meant that handshaking involved the app notifying Spin's API that the user was going to hire a scooter and then sending an unlock code back to the scooter via Bluetooth. Locking was the inverse, which left plenty of opportunity for state to get out of sync (server thinks scooter is unlocked but the unlocking failed, or vice versa).

It's possible that their launch was very much an MVP and they've been doing a lot of engineering work in the background, but they were way behind Lime and Bird at launch time.

(Edited to clarify that the unlock code is sent via Bluetooth)
More people in the US also can't take time off, or are at least discouraged to do so.

A yield sign implies that you must be prepared to stop if necessary anyway. Which means going at a speed where you can brake to 0 before being in the middle of the intersection, so maybe 20ft at best
As someone who's been looking for a first-class Linux experience on a mobile tablet for a while and been very underwhelmed by everything on offer, I'm pretty excited about this and am very curious how it compares with running Linux on the upcoming Slate.

The Apple keyboards were designed to be thin at the expense of everything else, reliability, maintainence, longevity, and comfort.
What do you mean ?

That the mind is created in by another piece of matter, other than the brain ?

Or that there is "something" that is not matter (that incidentally produces the brain)?

What is weird is assuming the existence of something that is not matter so that by definition cannot be observed or measured.

Personally I love to assume there is a teapot orbiting Saturn (cf Bertrand Russell)

Can you disprove that ?

It used to be fairly common. Lookup "Three Martini Lunch." When I was in the oil business several decades ago, it was quite common for 2 or 3 of us to ring up a vendor to take us to lunch where we'd have a couple of beers.

I won't say it's unheard of for myself and my colleagues to have a beer or glass of wine at a work lunch in the tech industry. But it's certainly a rare event though definitely more common when visiting Europe.

> As an extreme example, "Seat belts save lives" is an objective truth, but "Saving lives is a good thing" is an evidenceless belief. That is it believed by the vast majority of the human race in no way constitutes evidence.

I disagree: I am strongly opposed to force by violence (laws) to prevent people from doing stupid things to themselves. In this sense, I do not necessarily consider saving lives a good thing (of course, there do exist lots of cases where I do).

P.S.: I strongly recommend wearing seatbelts, but am opposed to seatbelt laws.

I don't have the exact quote in front of me, but in 1979, Douglas Hofstadter wrote in his book "Godel, Escher and Bach" something to the effect of: "It may be that some day a computer can beat a human at chess, but when it happens, it will be by the sort of computer that will say, 'no, I'm bored with chess, I would rather talk about poetry'". If Hofstadter can be wrong about anything, anybody can be wrong about anything.
There is an estimated 100 billion nuerons in the human brain. We know from information theory that DNA is not nearly long enough to describe all of those connections. This means that most of the complexity of the brain is emergent.

I envision bundles of neurons that begin their existence mostly disconnected... These bundles are described somewhere in DNA (but not their ultimate learned configuration) and so is whatever learning algorithm drives this process.

We will have AGI when we understand the underlying learning algorithm our brain uses... Personally, I believe that algorithm involves fantasizing future scenarios and learning from the fantasies.

And yet general biological intelligence arose from unintelligent forces? Hm, interesting.

I don't know enough about general artificial intelligence, but his claim seems to hinge a lot on what we already know. There are things we may not know yet that will lead to us generating general artificial intelligence. Although I don't think it'd be required, it may turn out that the experience of consciousness isn't something we can mechanically produce but is a property of matter itself. Now, I can't prove that is so but it's a fun little hypothesis I enjoy thinking about. None the less, there's no particular reason to disbelieve why humans couldn't figure out similar knowledge and apply it to creating better artificial intelligence.

Some of his reasoning is just flat out fallacious:

> An overwhelming amount of evidence points to this simple fact: a single human brain, on its own, is not capable of designing a greater intelligence than itself. This is a purely empirical statement: out of billions of human brains that have come and gone, none has done so.

Yet out of all those billions of brains, how many of them have tried developing general artificial intelligence, let alone the "AI" of an if-then-else statement? Probably 0.00001% of those billions of brains. Yes, I made that number up, but it wouldn't be surprising for that number to be minuscule, below a fraction of a fraction of a percent.

Evolution has had billions of years. We've only had computers for less than a century. In that respect, it's not at all surprising that humans haven't mastered what nature unintelligently developed for much longer.

> In particular, there is no such thing as “general” intelligence. On an abstract level, we know this for a fact via the “no free lunch” theorem — stating that no problem-solving algorithm can outperform random chance across all possible problems.

That depends on how you define the word "general". I don't think that scientists and engineers working on intelligence are actually using the word "general artificial intelligence" in the sense that such intelligence could solve literally any problem. Humans are generally intelligent within a set of fixed domains, but that doesn't mean they don't have general intelligence within certain constraints.

In the full article, the author addresses this. He argues a human's intelligence is more externalized in society than physically located within his/her brain.
Another perspective, from a skateboarder:
In New York skateboarders are banned from sidewalks and have to skate in traffic. I've got a solid push and hold my own among bikes and cars but, regardless, get all kinds of flack from drivers. When I take the to sidewalk due to dangerous road conditions pedestrians are simply far too unpredictable, scared, and oblivious to permit me on board so I reluctantly walk.
You know who I never see walking when they're on the sidewalk? Scooter riders, electronic and otherwise.
Good question, and something I didn't have the space to cover in this article. The answer involves "physical properties". Physical properties are interesting characteristics of an expression that impact its layout, presentation, or location, but not its logical content. Examples include row order, column naming, and data distribution (physical location of data ranges in the cluster).

As an example, consider a memo group that contains both a MergeJoin and a HashJoin operator. The MergeJoin "requires" its inputs to be sorted on the same key. If an input is not already sorted, then we insert a "sort enforcer" operator that will provide the required ordering. Of course, that increases the cost of producing the input, which the optimizer must take into account.

So, getting back to your question, for any given memo group, we always select the equivalent plan with the lowest cost, for a given set of physical properties. However, that has the effect of sometimes selecting a memo group operator that has a higher cost, because it "pays off" higher up the operator tree. Back to my example, say the SQL query is something like this:

SELECT * FROM a, b WHERE a.name=b.name ORDER BY a.name

The lowest cost plan might use a MergeJoin, because its output is already naturally sorted on "name". However, the input to the MergeJoin might be higher-cost than logical equivalents, because it must be sorted. Therefore, we have the situation you alluded to, where we choose a higher-cost subtree because it minimizes the cost of the larger tree that contains it.
I love this idea. With insane mobile processors, terabyte storage on phones, external GPUs, and USB-C docking, we're tantalizingly close to "I do my computing on this device. It's in my pocket with a phone interface right now. But once I plug it in at my desk with the GPU dock, it's my computer. And later, I'll throw it in the tablet and use it on my couch."

Backups will need to be good and easy if your main computing device can fall out of your pocket on the subway, and an OS which is happy doing this will need to exist. But for many people, this could be a beautiful world.

The human mind certainly involves systems other than the brain, like the limbic system. Even the face is involved in communicating emotion between various parts of the brain, which is why you can make yourself happier by smiling.

But it seems extremely likely to me that some arrangement of material could create a mind that, if not exactly human, we would recognize as intelligent and useful.

If you're skeptical of the materialist assumption, a productive line of inquiry is to investigate what capabilities of a mind can or cannot be replicated by computers or other material devices. That probably looks a lot like doing AI research.
We are at the point where each consumer's spending on Cable TV is now transitioning to "Streaming Services" a.k.a. Cable 2.0. In the end "Cord cutting" will not save money; it will simply mean that instead of paying Cox or Comcast, the consumer pays monthly for Netflix, Disney, Hulu, HBO etc.

When there are too many separate streaming services (that there are too many $10 monthlies from each service coming to the house) they will be bundled together and sold as "TV," most likely by Cox or Comcast.

This will all be surrounded by a huge amount of marketing, but the bill will be identical: around $60/mo for the basic package and $120/mo for the deluxe package. And everything that was old will be new again.

And watch too, as ads find there way in somewhere in the process. They are already in the form of aggressive product placement, and some paid streaming services (Hulu) are rolling them out.

Exactly. The way I think about it is that logic is a wonderful tool for ensuring your beliefs are consistent and helping you implement them effectively, but it's incapable of determining what those views should be.

Put another way, you can only have a logical argument with someone who already agrees with your beliefs.

No, because certain groups in society prefer doing different things on average and certain jobs require certain capabilities which are not evenly distributed among those groups that people tend to measure.

The decision what to measure is a problem in itself which what the OP is trying to say, we tend to look at skin colour and gender, what about height, IQ, chest hair, glasses, political tendencies, levels of aggression and whatever other measurable classification I could find?

Equity of outcome usually means a gulag or a concentration camp, that's the only place where there is equity of outcome and that's the destiny of any society which aspire for such a ridiculous idea.
