Yeah this is true, typically you want to keep blocking functions outside this. By default, core.async allocates as many threads as cores in your CPU.

In addition to this, I personally find core.async to deal poorly with flow control (e.g. slow subscribers slowing down the entire flow for every subscriber), and seems to not have a lot of telemetry / it’s difficult to find out what’s going on in the thread pool behind it.

I’ve personally settled on Zach Tellman’s Manifold library, which provides a much more sane abstraction and is fully compatible with core.async.

For some addition thought and material on these topics, I highly recommend watching this talk by Zach, “Everything Will Flow” https://youtu.be/1bNOO3xxMc0

Mind explaining what you mean by 'negative momentum'? I'd never heard of Pony before and only took a look at it just now.
I'm sorry, but that's such a non-answer. Of COURSE he could donate more money to the US Government. The point is that he thinks structurally the system should require that he and OTHER people like himself should have to pay more. By changing the structure, they change what people optimize for, and ALSO, at the same time, raise funds.

As a philanthropist, I'm sure he personally feels that he's able to direct his money to more useful causes than the government does, just as many rich people who give nothing also make the empty claim that the government would just 'waste' their money. The difference is, in his case, he might well be right. But that still doesn't mean that a structure that taxes him and others like him at a higher rate wouldn't have a net social benefit.
> Everyone and their cat wants to live as close as humanly possible to the hip center of the hip city.

I don't agree with this assumption. Most people just want to live reasonably close to their job, a grocery store, and maybe a few restaurants, while having enough space that they feel is sufficient. Maybe add in some constraints for feeling safe or being in a decent school district.

Ask HN: Re-coding software from old job?
I am considering coding from scratch some of the projects I had done while at my old job and release them as open-source as a way to build my portfolio. Any advice? There are some caveats:

1. I have an IP agreement that doesn't state anything about reproducing the work.

2. None of the projects I consider coding again compete with the company's services. I would only consider coding similar underlying infrastructure.

3. How close is too close? I am obviously allowed to continue practicing my craft.

4. In case you're wondering, no, I don't have any of the code. This would be all from experience and it wouldn't be the same line for line. I.e. if this were a school project, I wouldn't be plagiarizing myself.

5. Lastly, I don't wish the company any harm, I am simply trying to build a portfolio.

I disagree with basically everything you just said.
An AI might not have a goal.
If it did, its happiness may or may not be related to the distance from the goal. It might not evaluate every situation and action with regard to it's (presumed) goal.

I don't think we do have a (single) innate goal. Everyone has different goals, and they are not innate.

Emotions are not a map from a present situation to a goal. AI might not have emotions.
When I lived at my parent’s place the following scene always was a bit odd during the winter months:

“It’s cold.”
I've never liked advertising companies and have noticed a downward trend in the moral implications of different advertising business models.

The least creepy IMO is when you would see a television or radio host cut away to promote a product which directly tied the content creator to the promotion.

Later that became less common and advertisers approached content aggregators like Television networks who maintained a carefully curated collection of content this wasn't too bad.

The current trend of advertising companies selling ads on non-curated, user generated content seems to have crossed a line where major problems are just inherent. I think a better arrangement would be if Google and Facebook allowed content creators and advertisers to directly connect thereby allowing each to choose what sort of brands match their particular image.

I misspell more words on a mobile device than a real keyboard. I used to use IRC over an ssh terminal and would occasionally connect using my phone when I was out of the house. The app wouldn't do autocorrect for anything typed into the terminal so my spelling was atrocious due to hitting the wrong buttons sometimes. At home using a real keyboard, I had a much easier time. I still spelled words wrong but those were words that I just don't know how to spell.

Absolutely - this challenge is especially acute for all ecommerce retailers with broad catalogs. Target, macy’s, walmart, jet, etc all face this challenge.

Systems like Solr, elastic search and endeca (out of the box) all assume relevance means keyword frequency in a product page, with some weighting depending of title, description, tag, etc. Delivering relevant results that users might want to purchase requires taking these systems, adding or customizing their NLP techniques, operationalizing historical user search & purchase data to determine intent, personalizing by shopper history, etc.

The challenges of massive heterogenous catalog affect other areas... Chief among them search result personalization… an individual’s gaming purchase history might cause ‘button down’ to return gaming keyboards, rather than oxford shirts, while a pet products purchase history could lead to a search for turkey returning turkey dog food.

The fact that Amazon fails to personalize search results is evidence of the difficulty & opportunity here. The sort of pervasive personalization found in AirBnb, facebook, google are simply out of reach of most ecommerce retailers…
Looking back at old Thinkpad models, I wouldn't be all surprised to see Debian Stretch and Firefox on a T20 from 2000, if it had full memory upgrade (to apparently 512M). 600X from 1999 might be the limit (first PIII model). Much beyond that I feel things start to get much sketchier. You might start to run into ISA issues with older CPUs or memory limits. Additionally 90s laptops especially might have had more exotic peripherals which might not be fully supported anymore, if they ever were. Going below 1024x768 resolution would be problematic also.

For more practical use I'd draw the line to 2003; with T40/R40 you got USB 2.0 and Wifi, both things that make life much easier. From spec point of view you got Pentium M CPU (with SSE2 and all) and top end models shipped with 512M of RAM (upgradeable to at least 1GB!).

That also serves to demonstrate what dramatic progress happened in just 3-4 years.

The next 3-4 years also saw fairly significant improvements, T61 from 2007 has SATA (allowing SSD upgrade) and first 64 bit CPUs, supporting up to 8 GB of RAM. That gets you in the realm of mostly practical daily driver.

https://en.wikipedia.org/wiki/History_of_Brighton#Etymology

"The etymology of the name of Brighton lies in the Old English Beorhthelmes tūn (Beorhthelm's farmstead). This name has evolved through Bristelmestune (1086), Brichtelmeston (1198), Brighthelmeston (1493) and Brighthelmston (1816). Brighton came into common use in the early 19th century"
Before I was able to afford a car, I had a 2.5 hour commute to work involving 2 buses and a train and wait times. I can assure you that the last thing I wanted to add to my $50/week transit fee was an arbitrary seating system designed to encourage spontaneous interaction with others. Back then the magazines in my bag and Pro Evo 2008 on PSP were the only things keeping me going during those commutes.
Picking the space character, apart from being I think an established convention already (the CHAR(n) type in databases), definitely has the advantage you can just "blit" the filename onto the video buffer in text mode when doing a DIR command. You don't have to bother with checking its length or anything, just copy 11 bytes and insert a space (not dot in the original DIR listing format) after the 8th one. If the file doesn't actually have an extension, this just prints the right number of spaces so the other columnms are aligned.

EDIT: see https://en.wikipedia.org/wiki/Dir_(command)#/media/File:Spar... for an example.

It is a bit more complicated than that. The landlords are not raising the rent much (because laws exist already in that place) but rather 'offer' a new snow service (that you have to get, even though that we have maybe 2 half snow days a year) for 300 € a year, and a new janitor service for 50 € a month and so on. They upgrade your building (meaning you cannot really live there due to construction noises) and then put most of the upgrading price on top of your rent.

And finally, the big landlord companies do not exist due to success but due to big investment fonds deciding that it makes sense to buy many houses in such a cheap city. And to be honest, the actually good renting laws also play a big rule in this as they protect rents very good and such a single bad renter can become a big problem for small landlords. Also you have to cover so many restrictions etc that it becomes expensive/challenging to rent out (i.e my collegue is currently suing his landlady for a decrease in rent of 580€ per month due to an error in the contract)

For _me_, dealing with knee pain requires heavy squats and stretching. Sometimes it is mashing out knots from muscles where the knotted muscle is pulling on the knee in a bad way.

As others have said, it really depends on the person. Medical abnormalities can toss a huge wrench into this. In general, if you don't use it, you lose it. Do things that cause muscle to build and support joints and do some mobilizing/stretching.

> They did not like this. For whatever reason, which they refused to explain to me, they insisted I played their stupid mix that had been playing for months.

Could licensing have been the reason? Not sure about the US, but in Europe, you frequently need a separate license to play songs in stores, bars or really any kind of public venue. I imagine this is probably even stricted in the US. So the crappy mix might have been the only thing they had bothered buying licenses for - and they might have been afraid to get sued when playing anything else.

I still can feel the pain though, and I have no idea why the bosses didn't even bother to give a reason. So I guess quitting was the best thing to do.

An elementary school I attended from first to fourth grade would play Beethovan's Moonlight Sonata in the lunchroom as the song that signaled "quiet time," when we'd have to eat our food without talking. Occasionally we would get another song, something by Chopin I think, but in my memory 90% of the time it was Moonlight Sonata. Whenever I hear that song now, ten years later, I get teleported back to fourth grade quiet time where all I could do was stare into my carton of sometimes half-frozen strawberry milk or prod miserably at my collard greens (invariably quiet time came near the end of lunch when I had already eaten everything not terrible). I have an almost physical revulsion when I hear it.

It has been in my experience that people who are usually for the same ideology as the parent comment are also the same people who have never had a steep medical bill thrown at them after a hospital/doctor visit.

> You can't reason about ethics from the standpoint that whatever you are doing right now is known to be ethical.

An excellent point...but we DO reason about ethics. We can draw parallels from our decisions in other areas to see if we are being consistent. Even if we can't achieve objectivity we can try for it and thus get closer.

And from this I find I feel bad about the good to other living creatures I COULD be doing and am not....but that I don't feel sorrow for the lack of of sorrow and joy from creatures that are merely potential.

Perhaps you feel differently. Others certainly do. I just want to point out that it's something worthy of thinking about rather than tossing out a facile "existence is always better".

What worries you about the 100K number and what would a better number be?

As the article suggests, it's only 1,000 app servers with a connection pool of 100 each.

Alternatively it's 100 servers with a connection pool of 1,000 each. 100 app servers isn't excessive and if you're doing less than 10K concurrent on each of them then there's other profiling opportunities to be had there.

Scaling-up the database as far as it'll go is still a useful thing to do. DB technology over the last 10 years or so has made scaling-out the DB a more realistic prospect but it's still by far the hardest part of the stack to scale-out.

If you can get performance improvements elsewhere before the DB becomes the bottleneck, why not take them?
Well the problem is a "second" is just a unit of rotation of the Earth on its axis. So you'd either need to use some other reference material than a rotating body in space or else use some arbitrary one (like Earth, since that's where we are from!) and choose a reference date (why not use one we're all familiar with? I know! We could use the UNIX epoch!).

Even if you did this, your universal time would just be a synchronizing tool. Each human consumer would expect it to be translated into the most relevant time to them. If you think it's hard getting people to adopt a standardized date/time on one planet, every planet you add to the system makes that an exponentially more difficult task.

It's not necessary to use organic particles. We will probably soon build the electronic computer which will, from the perspective of the humans communicating with him, indeed behave "as a conscious person": soon we won't need you to write the answer you wrote, the computer will be able
