>I was talking about traveling between galaxies, my understanding is there's essentially nothing between them: no asteroids to mine. So you'd need to bring everything you might need in advance. But maybe I'm wrong, maybe there is a decent amount of debris floating between galaxies?

The current thought now is that there's likely quite a few "rogue planets" out there, and other asteroids that haven't gotten captured by a star. However, the density of such things is likely to be so low, and you won't know until you get there what they're composed of, so it seems like a bad idea to plan a trip assuming you're going to stop at a bunch of asteroids and rogue planets to pick up supplies; you'll easily make your trip far, far longer. Don't forget also the big problem in long-distance space travel is speed. If you want to get to a particular star system, you need to get up to speed and stay there until you're ready to decelerate. You can't afford to slow down and stop at a bunch of rocks along the way, and you'll be going far too fast to capture the small ones. Most of your fuel will be used in acceleration and deceleration, so you can really only do that once most likely.

>Whenever I think of what an advanced civilization would look like, I picture something like this (though not necessarily just machines). Something semi-nomadic, an entire civilization of ships in a big fleet, wandering together through the galaxy, stopping at various systems to gather some resources or explore the planets. Maybe the fleet breaks up and goes in different directions for a time, and rendezvous later.

That doesn't sound like an "advanced civilization" at all, that sounds like a nomadic gang. An advanced civilization will value stability, and stay on their home planet(s) where all their infrastructure is located. They may very well send out exploratory missions, but those nomadic wanderers will not be the civilization itself, just one small part of it.
It's very likely a ton of people, but it's also very likely nearly impossible to measure.

If you're the CIA and you're tracking the cell phones of say 10,000 foreign suspects for 10 years, and each of those phones is making 10 calls/week, you're at 50 million calls to analyze. You could probably look at the country code to get an estimate, but if the other side of the call is a foreign national in the US, they shouldn't count. If the non-US country codes happen to be owned by US citizens who may be traveling, how would you know?

Phones at least have country codes.. How in the world can you assign a country of origin to random email data or plaintext data through a router somewhere?
We bought Kindles for both of my kids, as they expressed a sincere interest. Today, those devices collect a lot of dust. I can't put my finger on why. With my son (7), I do know he seems to really enjoy books that include pictures scattered throughout the text (e.g. Geronimo Stilton). For my daughter (9), who reads very thick paper books typically in series, I really don't know - so has a huge reading appetite and reads every chance she can get. It may be she has much easier access to paper versions. She almost never has to ask us to buy her a book as she can just go pick one up.

I should ask her. I do sometimes wonder if there is a bit of subliminal affection for the covers of books, too, to reinforce one's personal identity, which you never get with a black mirror.
I'm not lying but my comment is being misinterpreted; I should have been clearer.

That's an annual comp number, not a quarterly. I was trying to say I see a certain rate of offers flying by to/from some people, at those levels.

Also; bear in mind that some of the offers are under the assumption that certain technology is rebuilt and/or replicated. (Personally I don't touch such offers). So it's not just a regular thing, it's folks attempting to hire to replace/replicate/compete on certain tech too.

The offers I've seen that are predicated on build a major new platform to support a firms activities, have included a guarantee for the first year (essentially a fancy perf bonus) given that the entire year would be spent deep in the bowels of hard systems work that would only come to fruition later.

(edit to add comment re why some such offers have a first year guarantee; being vague to protect the guilty).
If your trial is not over as of the date of this announcement, you get 12 months from your trial start date (mine started less than a month ago, and it now says 352 days remaining). If it was over and you only spent $3.50, and you don't seem to have the Free Trial flex banner message bar at the top of the page anymore, that's a bummer.

I'd recommend to see if there's any way for you to contact support and ask them to restart your free trial, while this announcement is still fresh.
I have (first initial)(mid initial)(last name) at gmail. Same as my HN id. And a very common last name! 16 months into my first job out of University I got a call from a headhunter intended for the other Chris Miller sitting 2 cubicles away from me. At my second and fourth jobs there were also other Chris Millers. And from my list of examples, most all have the same last name.
I do not understand how this is a problem. Genes that are beneficial are propagated. Genes that are detrimental are eliminated. Nature divines which is which by survival of the fittest. I want future humanity to have the best genes possible. How else will we fight off the robots?

The security process that has really worked for me is using the "forget password" as means to get a "login token" into my mail, which is protected with 2-factor auth.

I don't have to deal with password managers, maintaining their files. Or deal with multiple passwords.
Except then you're stuck in freezing temperature, with what is probably totally inappropriate mountaineering gear and odds are you've got an avalanche to dig yourself out of.
true, but that requires you to educate the market and do more convincing.

customers make a lot of conclusions (right or wrong) based on price.

JIT doesn't the solve the problems people want AOT for, though, including the require/load path issue I mentioned - you still end up having to ship your entire source tree / gem bundles. Which is part of my motivation for still plodding along with my AOT compiler when I have time (the other motivation is that I've learned more about Ruby trying to compile it than I ever would from just "normal usage")

> heavily lower the ranking (or completely remove from their index) any sites that don't meet basic performance and readability thresholds.

This seems like a much tougher problem than AMP.

From an API design standpoint, it is much easier to build and maintain an endpoint that receives data that must be in a specific, proprietary data format instead of an endpoint that allows the user to input data in any format and then attempts to parse that data after receiving it.
Yup, Germans give happily money to other people. But Germans don't like to ask for this.
I second this... using the "remember password" as a token-based login + two factor authentication has been the best login method for me.
That is what I was trying to say. Apparently there is some number of designers that believe that that whole email verification process is too much friction for registering a user, so they simply opt not to do it at all.
How I did it for an ebook:

1. Set up Google Ads for your product to drive some traffic to an hidden web page

2. Set up A/B testing for your product with a range of different prices. I set up six web pages with prices ranging between $5 and $100.

3. When users click 'Buy now', have a page saying that the product is not available but record the number of people who clicked it.

4. Calculate which setup generated the most income.

I'm sure that would go over really well.
Does Citus (Cloud?) have features that offer better high availability and failover functionality than what RDS provides? Managed Patroni and packaged workflows for zero-downtime failover would be quite interesting, but I don't see anything like that mentioned on https://www.citusdata.com/product/cloud.

Nit-pick: I believe there are no sorting algorithm in O(1) space: just keeping the index of an element takes log2(N) space. Most algorithms hide this fact by assuming numbers have an infinite range. If you do, then you can use a single data for any algorithm, given a sufficiently clever encoding :) (Just use a number base-N and then you got as much easy-to-access, direct-addressable storage as you want per elements.)

What about editing the postgresql.conf, pg_hba.conf, recovery.conf files, setting up archiving and doing the first base backup transfer? That's the actual hard part.

Logical replication doesn't replicate DDL commands either from what I know so far so that's another major problem.
Your intuition is wrong.

Potential energy is linear with height. AKA it takes the same energy to climb from floor 1 to 2 as 2 to 3.

Gravity is 32 feet per second per second aka you gain speed over time. In a vacuum 0 to 32 feet per second takes 1 second, 32 to 64 feet per second takes 1 seconds, 64 to 96 takes 1 second etc.

However, in the first second you fall 16 feet. in the next second you fall 38 feet because you where falling at the start of that second. Thus, it takes more energy to increase your speed.

PS: What's confusing about rockets, is your fuel has momentum. So, when use it your consuming the energy it took to get that fuel up to speed with you. Further, at low speed most of the energy goes into the exhaust not the rocket.

I have built quite a bit of karma on this account and using it as my default id now. Also, what matters is the value of ideas not who it is coming from - right? :)
Thinking about this a bit, it seems to be that clients talking to a server with OCSP stapling support could still make use of cached OCSP responses by simply omitting the "status_request" extension in the client hello, which would cause the server not to send the stapled OCSP response. I don't think any clients behave that way today, though.

I'm not certain how session resumption plays into this either. If OCSP is skipped for resumed session as well (which would be my guess), you'd probably not take that small bandwidth hit all that often.

As an aside, OCSP stapling improves your user's privacy quite a bit as well, by not giving your CA a list of all IP addresses connecting to a domain.
There is a middle ground, which is that you dont allow the free import of heroin into the country. Where you have uncut, known-quality heroin available as a tool to treat addicts going through withdrawal (or any other effective substitute), and where you (optionally) pursue only high level smugglers - people who are getting filthy rich peddling a deadly and addictive substance.

If we took even 1% of the total we spend prosecuting addicts and used it internationally, we could probably put a much more severe dent in supply. We already invaded Afghanistan, but in many cases helped the farmers instead of shut them down (this is a complex issue, opium is a much more valuable crop than food - but its a problem money can solve ). We could work with other countries to disincentivize coca production (again - the farmers that grow it can choose coca or bananas, guess which is worth more ?)

There are so many other ways to shut down the drug war, but the first place is to stop prosecuting people for possession.
I don't think you know what you're talking about.

For how many weeks were you on the medication? For how long were you in withdrawal? Heroin, hydromorphone, oxycodone, etc the withdrawal lasts 5-7 days. Were you in withdrawal for that long? I guess the point I'm trying to make is that most addicts are on much higher doses for much longer periods of time -- and the withdrawal is insane. Furthermore, there's a big difference between physical and psychological addiction. If there weren't, then everyone who takes prescribed pain meds for any length of time would be "an addict" because they'll experience a degree of withdrawal. If you identify as a drug addict, that's fine (though I certainly hope you aren't one!).

IV Hydromorphone is also, by the way, 5x stronger than IV morphine. Granted, that's a lot, but nowhere near 100x!
If you live N lives then the chance that this is the first is 1/N. I don't know about you, but I don't remember anything from any previous lives, so it seems to me there's a (N-1)/N chance you don't get to remember anything from previous lives anyway.
There are other options - for example illegal selling and manufacturing (like now), legal using (so current addicts are not prosecuted for getting help).
So if you're observing a rain forest in Central America or a high mountaintop in South America, and you see some strange patterns or interestingly-stacked rocks, you think we should only look for non-human explanations for these things?

With this attitude, much archeological evidence of pre-Columbian civilizations would never have been found. In fact, the entire field of archaeology wouldn't exist.

For me, my biggest beef with Unity was a death from a thousand papercuts. EG: i wanted to open a file in a program and had to navigate to the location, and couldn't just copy the folder path as I did on Windows. Or when I wanted to Alt-Tab between two windows of the same program, I couldn't do it with Alt-Tab. To remove it, the forums told me to launch a program which then for some reason didn't open when I double clicked on it. And then I realized that Sublime Text was not longer called Sublime Text but Ubuntu somehow renamed it to the last file opened as admin, which was aparently a well known bug with Unity.

Then I read that the next version of Unity is a rewrite from scratch, with usually means many new fun bugs, and just said 'forget it'.

Now, is any of these DE simple to use and with well-thought defaults? I can try out a few ones (after all I will do a clean wipe of my desktop) but sadly don't have the time to test more than a few DEs.
Really? I find that really surprising. Because VS itself isn't anywhere close to a wonderful text editor.

Like most IDE's, it is a mediocre text editor with a bunch of compelling (for certain workflows) tooling for project and build management, debugger, etc. Plus usable introspection. As a text editor though, a solid C+ at best.

Is VS Code someone doing something radically different?
Not to pry, but did it start with a doctor's prescription for you?
We don't use Patroni or any of the other off the shelf items. We rolled our own primarily from our years of experience on Heroku Postgres. We're actually working on a detailed post on how HA and disaster recovery works for Citus Cloud, though the core mechanism powering it all under the covers is our state machine. You can read a bit about how it works in this post: https://www.citusdata.com/blog/2016/08/12/state-machines-to-...

If you are hanging onto a piece of debris, do you want to try to let go of it before impact? I'm assuming it's something with more drag than you, so presumably you're hanging under rather than surfing on it..

Although that's another interesting question. Maybe there's debris that wouldn't be particularly useful in slowing your descent, but could be useful to break your fall on impact... I can't immediately think of something that would be sufficiently good at that that it would be worth carrying with you though.
> Most people (at least myself) got into coding because they enjoy creating something from nothing. Maintaining and testing code is boring because it doesn't really do anything new, it's mostly fixing edge cases.

A good testing setup can be an alternative to redundant manual testing. This can really help speed up the creation process (for me, at least).
Working with a PhD student to do economic analysis is overkill for an early stage startup.

I would use the methods outlined by other commenters to create a set of potential price points. Pick the highest one and revise downward (or upward) as needed.

If you're solving a real pain point, there's a set of early adopters who will pay a high price for your solution. If this isn't true then I would examine product / market fit.

Mistakes to avoid:

1. Doing a "name your price" promotion.

2. Thinking you've found the golden ticket of pricing and sticking with it. Pricing should be scrutinized early and often.

3. Charging too little. At least some users and reviewers of your product should be commenting that perhaps your pricing is too high. You're charging too little if no one is complaining about pricing. Of course, you've charged too much if everyone complains.

Finally, how you present the value of your product is perhaps more important than the pricing. See here:

This is actually a good insight and I agree with it. However, I don't think it contradicts the essential statement. The wiggle room is in "however poorly."

So you might want to edit it, but finish the first draft. You might need to tweak it, but finish the first version that actually works.
I don't know about very specific applications, but I think the field itself and is very complimentary to CS, especially when considering finite or discrete structures. As it's name suggests, abstract algebra abstracts "nice" properties of, e.g., integers and formalizes them in a very concise and general manner. Modern abstract algebra is deeply tied to category theory, and so now these "nice" properties get abstracted even further out to maps between objects, and as maps between categories (i.e., functors). As such abstract algebra is tied to functional programming on some level (I know nothing about this connection though).

Linear algebra is a subfield of abstract algebra, and lots of general theorems about what classes of matrices are diagonalizable, or what their eigenvalues look like, etc. are within the purview of abstract algebra. These types of results are relevant to many algorithms, e.g., page rank.

Aside from that, I think abstract algebra is quite a beautiful field in its own right. Two books I would recommend are Artin's Abstract Algebra (as an intro) and Lang's Algebra (more advanced, good bridge into the category theory perspective).
Calling it "a whole world of investments" is a little extreme. Access to almost all asset classes is available for even the smallest of investors.

Absent a mysterious Renaissance-like trading algorithm that magically prints out-performance, diversification is the only free lunch, and it's cheap and easy to massively diversify these days.
I'm not arguing that they're wrong. I'm arguing that it isn't in any way a solution to the problem of paying for dental care.

> Do you believe that heroin should be available for purchase, like e.g. cigarettes? Is this a matter of individual liberty, or some other reason?

I'm not the OP, but I think so, precisely out of a concern for individual liberty.

There are also prudential concerns, e.g. that criminalisation actually results in worse outcomes for addicts, dealers & society. But even were that not the case, I'd be in favour of legalisation.
Citus Cloud is perhaps most exciting me because it has tremendous momentum: as the combined product of deep technical expertise meeting top-flight open source software meeting tons of end user experience, it's quickly outpacing platforms which are locked-in anachronisms. Take Redshift: Postgres 8.4? After you've used some of the features in 9.6, it's hard to go back. It'd be interesting to see some numbers around Citus Cloud's battle-tested deployments.

As a side note, these blog posts on high-level techniques and open source tools (e.g. PgBouncer, wal-e) are useful for anyone considering deploying an on-prem version of Citus as part of a product – thanks, Ozgun!

Usual disclaimers apply: not an employee, but big fan of the team and technology and it's great to see them gaining well-deserved mindshare.
excellent idea.
