Incorrect, movies are not automations, they are simple data sets. Movies+players combination is, yes. But this definition from the parent comment is an oversimplification. This is how the article framed it and its TL;DR:

"living systems may be defined as open systems maintained in steady-states, far-from-equilibrium, due to matter-energy flows in which informed (genetically) autocatalytic cycles extract energy, build complex internal structures, allowing growth even as they create greater entropy in their environments, and capable, over multigenerational time, of evolution."
Yup, supposedly Lyft is actually worse. NerdWallet recently did a survey that showed Uber drivers making $15/hour versus $11/hour for Lyft. They did concede that tips gave Lyft driver's the possibility of making more than Uber drivers, but now that Uber has tipping that's a moot point.
Dealers don't usually volunteer it, but you can just ask your salesperson for the money factor. Take the number and multiply by 2400 to get the interest rate. My current lease rate is 0.75%, while the interest rate on a loan would've been 1.9%. The lease worked out to be cheaper than buying. Some car companies also have a multiple security deposit discount that lets you further reduce the money factor by a significant amount.

> As dead tuples continue to accumulate in the index, Postgres enters a hot loop as it searches the B-tree, comes up with an invisible tuple, and repeats the process again and again, surfacing empty-handed every time. By the end of the experiment illustrated in the charts above, every worker trying to lock a job would cycle through this loop 100,000 times.

1. I am curious if the author tried setting the autovacuum more appropriately for a table that is in continuous use at 50 new rows/second.

This article (http://okigiveup.net/postgresql-vacuuming-an-introduction-fo...) suggests:

ALTER TABLE person SET (autovacuum_vacuum_scale_factor = 0.0);
ALTER TABLE person SET (autovacuum_vacuum_threshold = 4000);

This should result in entries being removed from the index and table regularly.

2. If I understand correctly, it seems the other part of the problem is that there are lots of rows to be individually tested to see if they can be locked, based on the way the author has implemented their queue. While lock attempts are being made on a set of rows, they aren't being deleted, since they're 'in use'. This non-deletion causes things to get out of control.

As far as I know, 9.5's SKIP LOCKED is meant to help address that (https://blog.2ndquadrant.com/what-is-select-skip-locked-for-...). Though it appears to be doing something kinda similar under the hood.

If the author of the original article (@ brandur.org) is following this discussion I would be grateful if they could evaluate these two options in the context of their test implementation.

Ask HN: Have you ever rewritten the code for your product from scratch?

Your experience corresponds to mine almost exactly, have you written anything about your subsequent attempts, and the one that finally succeeded? No contact info in your profile btw.
If you have ever spent a non-trivial amount of time in a bar, you can see that people with credit cards run up tabs due to a myriad of events that include intentional bad decisions or irresponsibility (like being too drunk to remember to pay before jetting off to another destination). These tabs are generally held for a number of hours, days or weeks (depending on familiarity with the parties involved) before being elevated to a more serious consideration.

A business that fails to innovate goes out of business. These kind of zoning restrictions would hit all the businesses equally, and force them to improve their work from home policies (isn't that what software engineers want anyway?) and establish more organized/efficient ride sharing.

Besides, the new zoning restrictions would only apply to new campuses being built. And we already have cities like Palo Alto debating whether they even want more jobs in their city, and rightfully so. There are other places to build your campus. Silicon Valley needs housing, not offices.
Product information. Things like "The mainboard named XY from producer ABC has the manufacturer sku 1234567, the EAN-13 00123... and the UPC 01234...". Ideally add to that the custom specs, like "it has that many usb slots and this socket" etc.

But I think I miss part of the picture here, there is probably a channel transmitting structured information like this from manufacturers to vendors, I just never found it.
The source I linked mentions that the primary route fentanyl takes is from labs in China to Mexico, then to the US.

Yes, we are in agreement then. I just don't think the epidemic (or the deaths) is as easy to stop as ransom1538 thinks, because the fentanyl problem by itself stems from trafficking instead of prescriptions. AndYou can't really stop the drug trafficking part of things very efficiently, see the DEA for proof.

Personally I believe that the deaths are secondary to the addiction anyway. Of course, it's very, very bad that people are dying due to adulterated heroin, but the most effective way to lower deaths is probably to prescribe less of those 12hr oxies.

>That word, "property", gives the opposite connotations of "copyright"--permanent rightful ownership vs a temporary grant of monopoly on an idea.

I'd point out that generally copyright protects only executions of an idea, not the idea itself. This is pretty much on what for example the existence of GNU and Linux hinge on; they implement the idea of UNIX despite AT&T claiming copyright on UNIX.

Patents, on the other hand, do extend to ideas, and are completely different story.
Check out your university job board. There are usually some great jobs, working at the computer lab, monitoring things at the physical plant/maintenance, scanning documents, lots of easy fun places to work, some where you are even allowed to do homework while getting paid.

Ask HN: 2 apps, 1 server?
Hi HN,

I'm currently working in a project that implies to develop an API (Rails + Postgres) and a Telegram bot (Python).

I have access to one server, so I'm looking for the best way to allow those two apps to live together. Some ideas:

* Run both apps, different ports

* Redirect an API route to the bot internally (I don't like it)

* Use another Python app to redirect routes to the right app.

Do you have any suggestion? I read about using multiple apps on the same server, but what's the best approach?

Thanks HN!

Why would anyone care about IPFS? Presumably someone pays for hosting to get their content shared. But if other forms are cheaper, what does IPFS bring to the table such that someone would pay for your pinning service if its not cheaper or anonymous? And why wouldn't someone just use AWS and run their own node to pin it?

Just set up virtual hosts. One for each app?
In this case, the unreachable states don't partition the space in a meaningful manner, nor does the system start in an unreachable state, so the only effect is that those states occur with probability zero instead of with very low probability in the stationary distribution. There are also very few (N) of those states compared to the total number of states (about N^(2N) if I'm estimating right), so removing them has very little effect on the overall statistics.

For a more interesting example, suppose that on each round, everyone with money picked a random person and gave them 2 dollars (and take N even). Now you'd have a Markov chain that is reducible in a nontrivial manner -- think about the parity constraints.
I definitely agree with you on this. I'm from Leeds and my first thought was that there isn't really a term for someone from Leeds, other than someone from Leeds!

Leodensian might be a term that existed at some point, or is by lack of an alternative, the default word, but it isn't actually used to the point where any person from Leeds would expect another person from Leeds to understand the term (let alone someone from elsewhere)

Now I think about it, I can't think of many names for citizens of the main yorkshire cities (York, Sheffield??). Perhaps "yorkshireman" or "yorkshirewoman" has been enough...
Pre-9.5, you could use "SELECT ... FOR UPDATE NOWAIT" to achieve the same end.
I'm disinclined to attribute them with having much of any point at all. Their discussion is too brief, and their presentation style is more clickbait thance science. They tout a counterintuitive result (It's really not, at least not for anyone used to thinking about data or state changes, certainly not once you think about what the 4th or 5th state change looks like) And then it ends the headline with the overused, even in for content farm clickbait, "you'll never guess what happens next". This tells me they're less interested in discussing an interesting result than getting eyeballs on the page via a shallow observation passed off as insight. If there's a deeper point to be made, they haven't made it.

As the sibling says, org-mode easily delivers here. In ways that makes standard notebook environments somewhat frustrating with their limitations.

Examples:

You can reference data in a table of your page.

You can access the "session" of a code block in a repl. Useful for putting credentials or other sensitive data in.

You can copy from in a result or a code block with the same ease.

Any tags you have setup will jump as expected. Same for completions and documentation.

Arguably, the way images are referenced externally is better for post processing.

Finally, being able to source control the document easily is huge. Json is a terrible format. :(
As far as the 64 vCPU finding, that's quite possibly because it's crossing NUMA modes. GCE's virtualization hides NUMA information unfortunately (at least as far as I've ever seen), so there's no way to handle this in software even.

But they took hundreds of millions in normal funding and hundreds of millions in debt sort of funding this decade. The vast majority of their funding. Wasn't most of that funding and growth of Jawbone going with the company trying to semi-pivot into wristbands (UP) along with their services? And a bit of the Bluetooth speakers I guess.

The 11 or so odd years before that were their Bluetooth headsets only. I think Jawbone could fit into this list. It's sort of like a spinoff company using initial foundations around 2011. That's not a good sentence or way of wording it but I can't think of something better right now. Still, the expectation from 2011 onward was huge growth with all that funding. Unlike their first 11 years.
And the insurers saw how wrong it can go and how much the payouts for such could be. This then was fed back into the risk / premium calculation equations and have kicked out a new, higher number for festivals that lack a history (and even those that do have a history, as the risk has gone up too). Furthermore, as insurers tend to spread the cost around (the festivals with a good history, and the festivals with little or no history), the festivals with a good history will pick up a bit of additional cost for insurance to make sure that insurers have enough to be able to cover possible losses.

I disagree with your premise, which makes the error pointed out in above posts -- accepting the idea of "intellectual property" as though it were analogous to physical property.

But the reality is that there is no such thing as "owning" a copyrightable work of expression like Bob Dylan's lyrics. Instead, some people have temporary legal control over who may copy those lyrics and for what purpose. There is no moral or legal sense in which someone else "owns" those words on the page in front of me and I am not in any way "leasing" or "borrowing" the words. However, they may still try to restrict what I can do with those words.

So DRM is about technologically limiting others' rights, usually in some way above and beyond legal limitations. For example, if you buy a DVD, you legally have the right to make copies for personal use, or e.g. use 30 seconds of footage in your own work of art. But DRM may prevent you from exercising those rights.

However, I completely agree that it is misleading of companies to use the word "buy" when what you're acquiring remains under their control, not yours.
Do papers submitted to electronic-only repositories like ePrint really still have a "distribution model based around print"? They might have if they are submitted to traditional journals as well, and having a PDF version as well is desirable for various purposes, but IMHO it's not so clear cut.
I have never encountered such an abnormal workload. This is also less likely to happen in Broadwell Xeon and up, where last level cache can be partitioned. And this is also less likely to happen on Google Cloud in particular, because Google uses high end CPUs with tons of cache.

I spent the first half of 2016 helping a drug and alcohol addict kick her habit of 20+ years. 6 days inpatient detox. Would have had 30 days rehab if she'd stuck with it.

Had lost her driver's license years ago. So after she checked herself out (admittedly, upon my investigating, for some legitimate reasons vis a vis that program), I spent the next couple of months driving her to meetings, providing childcare to make that possible, helping her get to the job her sister found her, then the second job. Making sure she wasn't alone in the evenings, when she would drink...

My major point. 6 days at one of the area's premier hospitals. Thanks to the ACA expansion of Medicaid. The rehab program would have gone under that, as well. Foodstamps for her and her kids. A social worker and case management for her daughter (living with grandma). Etc. Etc.

I had some warning signs, early on, but I hung in there -- advice from experienced friends and experts advising patience. And thinking not just of her, but of the kids; things seemed to gradually get better with them once I got involved.

Anyway... Not just my support. All this public support. That I don't begrudge: Treat the problem. Take care of the kids.

Come fall, she's back together with her ex-boyfriend, who was a big Cruz supporter. ("The Constitution! La la la, blah blah blah...")

And she -- previously having stated her indifference to politics, except for hating Hillary for whatever gut felt reason -- starts expressing herself as a big Trump supporter.

I'd explained to her, early on, that the ACA is what enabled me to keep insurance. I don't get a tax break. It just gives me the opportunity to participate, whereas before insurance companies would look for any pimple as the basis to exclude me.

She gained sobriety through the support of the State, and someone who depends on the ACA for his own well-being.

None of that seems to matter to her.

This experience has caused me to fundamentally rethink my ideas about how the world works and how we can (or can't) tackle these problems.

Writing about all this makes me feel kind of small. Laying the situation out there and sounding aggrieved.

But I do it, all the same, for the point it impressed upon me: I'm no longer sure some people can be reached, through any level of action and good will.

It's a pretty sobering -- and saddening -- perspective.

P.S. We've been out of touch for months -- her choice. As far as I know, she's still sober. Making plans a year out.

She's doing ok. But there seems to be no connection in her mind with providing that opportunity to others.

I've been forced to realize and acknowledge that some people appear to be in it purely for themselves. They can exhibit charm and engagement in furtherance of this purpose. But real empathy and cooperation?

And, looking around, it's not just the addicts and "miscreants". There's a significant portion of the population who really does believe and follow "I got mine". And that is all they really respect in others.

It is, it turns out, a dog eat dog world. At least when it comes to dealing with these people. Who, en masse, present a formidable problem to a functioning society.
> Cool people, so much opportunity, and you get to live in the heart of a rising super-power.

You probably have never lived in China. China has an authoritarian government that censors everything (last checked, livestream and korean pop music and every good external websites outside China), which means there's no such thing as 'cool' in china except dictated by the government. People in China are mainly concerned with making money, and getting the heck out of China.

As for opportunity, China's stagnant economy (crashed stock market, 2nd bubble bursting in shanghai real estate) and middle income trap status means that only Chinese citizens are preferred in any opportunities. Thus restrictive visas and anti-foreigners sentiments abound. 300%+ gdp/debt ratio and strict capital controls mean that the economy is basically one black swan away from a collapse.

Rising super-power.....only people who believe that are the wumaos that Chinese government send out to perpetrate western websites. There's nothing cool, innovative, or powerful about China.
