Let me start by apologising. My comments were snarky and I shouldn't've said what I did. It's now too late to edit them, but perhaps it's better to let them stand anyway.

With regards links, no, I don't have any links to pages explaining the technology. The best I have is this one:

http://www.eskimo.com/~billb/amateur/vortgen.html

There's a lot of stuff scattered around, but I've never found a single, coherent treatment.

The reason smoke/air/fluid rings happen, in short, is this. Throw a lump of air forward. The air in front of it gets pushed outwards to let the lump through. As the displaced air streams around the outside, it drags on the lump, causing the front face of the lump to follow the displaced air. That makes the front flow around the outside, and then the back comes forward through the middle to replace the air at the front, and hence you get a toroidal circulation.

(in truth it's more complex, but that's the basic idea)

Here's an animation that shows the idea.

http://www.amasci.com/wing/smring.html

That site has much that's poorly expressed, so don't take it all too seriously.

Making air/fluid rings is pretty easy, just throw a lump at a sensible speed. They turn up everywhere, but there are some surprises. Send a smaller, faster ring after a larger, slower one. The faster one catches up and goes through the larger one. The larger one even gets bigger to let it through, then shinks, catches up and goes through the other. You can get "leap-frogging" smoke rings, which is cool.

http://serve.me.nus.edu.sg/limtt/video/leapfrog.mpeg

All the basic fluid-dynamic ideas are Newtonian in principle and you can treat air as incompressible, near frictionless marbles flowing around.

Until you can't.

ADDED IN EDIT:

Collisions between smoke rings are interesting, both head-on and oblique. Most of the time you get a spray of smaller rings, each made half from one, half from the other. Or so I'm told - I'm still hoping to get the opportunity to explore that situation sometime.

HA! Found video:

Finally, bit puzzled as to why this comment is getting down-modded at the moment since I'm trying to contribute interesting stuff. My guess it's the same person who down-modded the grandparent to this comment, and wants to punish it further. <shrug> I'll live with that - it was more snarky than I intended, and inappropriate for HN. We all make mistakes.
I'm quite sure that there are some software that is impossible to run on Wine. Drivers and other stuff that touches the kernel comes to mind.

And ReactOS does make Wine better as they share some code:

"ReactOS works with the WINE project to share as much programming effort as possible. ReactOS depends on Wine mainly for user mode DLLs. Where appropriate, patches to Wine are also submitted by the development team, and patch contributors are often directed to Wine if it is felt that the patches would benefit them." <http://www.reactos.org/wiki/WINE>;
That's a very strong claim. I'm not sure I believe it - do you have a citation?
Take a look at this posting on Quora for a related discussion: http://www.quora.com/Do-the-terms-ninja-and-rockstar-come-of...

The general sentiment is that it is neo-corporate and shows a lack of understanding and lack of concern about substance of candidates.
According to some quick searching, pets and their food, etc. in the US in 2009 was a $45 billion industry.
The smart middle ground would be applying good technology/product entrepreneurship to the finance industry. They clearly have the money to play with and what may seem simple to us is wizardry to them. Someone pointed out an opportunity to me yesterday re: illiquid real estate assets. My mind is blown. I'm sitting here fucking around trying to get a 300k angel round, and these guys are trying to get rid of 300mil. there's a lot of money to be had out there combining tech/product know-how with boring industries. Money is usually found in the unsexy places.
Add this to the list of things you're "sure" about, but shouldn't be.

Nowhere in the EULA for Microsoft Office (their most profitable product) do I find text requiring you to run it on Microsoft Windows. I read it top-to-bottom, then searched for "Windows" (which never occurs) and then "operating system" (which occurs only to warn you that they use your operating system to get to the Internet).
> I'm pretty sure he even used to make those same references when talking to his native British colleagues, using them to describe life in the former Yugoslavia & assuming they'd read the same comics as kids.

Reminds me of the claim – possibly apocryphal – that some undercover Soviet spies in the UK were outed because, when the conversation turned to Blue Peter (which supposedly every real Brit knew from childhood) they had no idea what that was.
> Dabaksol Guard Post Snowy Scene

That's the only one in the set that didn't let me down. It looks like someone took a Thomas Kinkade diner placemat and asked an 8 year-old to put some cannons on it.
Drones, like any other aircraft, would be used only after air superiority has been established.

That means that by the time we're sending drones in, the enemy doesn't even have sufficient radar capabilities to know what planes are there. Radar sites are one of the first targets in the process of establishing air superiority because they direct anti-aircraft defenses. They wouldn't even know there are drones to hack, just that missiles are raining down from above.

If we haven't established air superiority yet, we just use cruise missiles. But a cruise missile looks a lot like a missile fired from a drone if you're standing on the ground.
>The volume control operates on the preamp section

I'm aware of this - you'll notice I mentioned the volume control specifically for the Schiit gear, and not preamps or power amps in general. If you're using separate preamps and amps, then yes, turning down the volume on the preamp isn't going to matter. With almost all headphone setups, you are doing all volume control on the amp though, and none on the dac - it's pretty rare for there to be a dedicated preamp in the chain when dealing with computer -> headphones.

>Turning down the volume will do nothing

Again, specifically referring to the Schiit gear here, with the volume control details being specifically from them. Sorry if there was confusion and it seemed as if I was saying this in general.

>Being "high-end" is no excuse, cut-off relays do not affect sound quality and they are not expensive. It's just either laziness or advertising to people that don't know better. Again, there is no reason not to install shut-off relays.

Plenty of the best gear out there will include power up sequence instructions - Amps being last on, first off, is something that has been pretty standard for decades. Like James Bongiorno said, even if a muting relay is installed, why tempt fate for no real gain? I'm sure I've got Cary and Audio Research manuals around somewhere with their power up sequences printed in them - are you going to accuse them of shoddy design as well?

My issue isn't with the relays - I'd love it if everything came with one. I don't think there's a downside to having them. (Though habit will keep me using the same power sequence I've been using for forever)

My issue is you've decided that anything that lacks said muting relay is poorly designed or not worth the price:

>No it's not, that's called bad design. Unless high-end now stands for "poorly designed gear sold for 10 times what they're worth"

It's audio equipment. Shouldn't the ultimate judgment on the quality of design be how it actually functions in it's intended purpose, and not whether or not it's the most convenient? Companies have been selling great sounding gear (that measures well) and lasts decades that lack a relay. I simply can't agree that lacking an optional piece that exists only to protect someone from something that they can perform manually overrides every other aspect of the product's design and makes it a poorly designed product.
"Polite society" or "polite circles" just means the upper class.

It was 1914, polite society was all about colonialism and "scientific racism." I actually read a excerpt of a textbook from that time period. The excerpt was "the races of man," crazy stuff.
> Why is there no efficient strategy to get them into the large number of empty mall spaces?

That's not uncommon, it's just that it usually presages the malls being sold and torn down because they aren't earning any money.
But have you even seen an app that remained paired to any piece of hardware whatsoever for more than a few minutes?

Using any form of technology? Without dropping one side or the other into an irreparable state that requires power cycling one or both ends at least once and then hoping for the best?

It’d be cool if it worked, by my expectation is that it’ll be implemented by the guy in charge of that YouTube “cast” app that has only theoretically worked one time in a lab in Palo Alto.
I don't know exactly what to say when reading this. I'm astounded that somebody could consider this a reliable explanation. Still, I can assume incompetence from whoever did that, but the person who drafted it is clearly in bad faith. How can that have no repercussions?
I have a hybrid (so it can be charged home, for 3000km we used only 50L of gasoline) - the EV drive is amazing, (if not spooky) - silent start, no noise, no vibrations (of course no exhaust), so it's great for city drive. For longer haul - there is the gasoline. For added benefit the total power of both engines engaged is quite impressive, along with acceleration.

Until there is a massive network that can reliably charge on the go, gasoline is there to stay. Also flip note: I know Norway loves EV (due to tons of tax breaks), yet EV do suck at lower temps (say below -10C)
The replication was redone around that time (not sure which version exactly). It's still working on the same principles though, sending queries and redoing them on each replica.

Before in short, the WAL was sent every minute and always 10MB even if there were no changes. Now it's more adaptive, actually doing nothing when they are no changes, and picking up quicker when changes begin.

I am surprised they don't mention this point because the replication was really unusable in PostgreSQL.

There are still spikes (write amplification) and other drawback from this design, but at least it doesn't shit itself under no activity.
So you’ll want to try dialling up the overall cache factor a bit.

Redis is only useful if you split the server into multiple worker processes, which you shouldn’t need to at that size (and even then, doesn’t provide shared caching yet, although there’s a PR in flight for it - we currently just use redis as a pubsub mechanism between the workers).

Highly recommend hooking up prometheus and grafana if you haven’t already, as it will likely show a smoking gun of whatever the failure mode is.

Are the logs stacking up with slow state-res warnings? Stuff like:

2021-02-25 23:15:26,408 - synapse.state.metrics - 705 - DEBUG - None - 1 biggest rooms for state-res by CPU time: ['!YynUnYHpqlHuoTAjsp:matrix.org (34.6265s)']
2021-02-25 23:15:26,411 - synapse.state.metrics - 705 - DEBUG - None - 1 biggest rooms for state-res by DB time: ['!YynUnYHpqlHuoTAjsp:matrix.org (148.6s)']
The most common workflow of git, to me, is when i want to move changes between branches (for staged and unstaged changes).

Is there example here ?
Actually the main reason is to limit claims of fraudulent transfer.

If adverse possession is 10 years in your state, you don't need to worry about the seller's grandchildren suing you claiming that you defrauded their ancestors when you bought your land from them. This also acts as a backstop for title insurance: title insurers are essentially off the hook for policies older than the adverse possession time.

The main goal of adverse possession has always been to protect people who bought the land from ancient+stale claims that they bought it through fraud or bought it from somebody who wrongfully claimed they owned it. Otherwise you'd have to keep documentation and proof for all eternity. At some point it has to be okay to no longer have evidence and documentation beyond what's in the public record. Torrens title systems don't change this: the point is to prevent egregiously stale claims of fraud. Fraud is the explicit exceptions to Torrens indefeasibility.

The much-publicized "squatters got free land" phenomenon is just a side effect.
There should be exceptions for such well executed visions.

It's true, but making the statement time-invariant is also an oversimplification. Time does not end with the fulfillment of the prophecy and everybody knows that. Where does $GME go after reaching the moon? It can only stay there or go down, and in both cases people would start selling it.

Hello! I am a software engineer with professional experience doing C++ and Java development. But, I was always interested in web development.

I'm very curious and self-driven in pursuing web development. I constantly learn new technologies and make new projects in my free time. I enjoy all types of problems from design to technical backend implementation details.

If you think I may be a good fit, please reach out. I'm excited to talk!
Doesn't Clojure have a pretty good concurrency story as well? (Which I find particularly relevant since it is a Lisp.)
This option is not working for me at all.

I wonder if it's because if I see a thumbnail of something unwanted, I first have to open the post in order to access the menu, so the the app counts it as a view first, adding the unwanted post to things I "engage" with.
The gap between the haves and have nots that will cause problems is between 0.1% and 90% to 99.9%, rather than the gap between 10% and 90%. I think.

And there is a lot of misallocation of resources as people try to hold onto their percentile, or spend an inordinate amount of resources trying to climb to the next one. I think.
Back in the days viruses had to hide themselves in executables to travel from machine to machine, undetected.

Today, as most users don't care about what processes are running on their system, and since the most common vector of infection is through the internet, what we call "viruses" are actually worms: they don't infect other programs, they are just self-replicating, malicious, executables.
That seemed pretty convincing, but then I added some comparison terms like "instagram" and "snapchat"... they are hardly a blip. I think that argues that the world is going mobile, but then maybe google trends isn't a fair way to measure who is walking where.
That's not true. Working 40 hours in a week is not a problem. A contractor can put in an unlimited number of hours if they wish. 20, 40, 80 - it doesn't matter.

The differentiator you're probably thinking of is whether the worker chooses which hours they work. If the worker decides independently how much they will work and at what times then the IRS doesn't tend to consider the relationship employment -- regardless of how much time is put in. This is precisely how these driving services operate.

If the employer is scheduling a fixed schedule, say 9-5 M-F, then the IRS considers it an employment arrangement. Regardless of the number of hours worked. But that is not at all how these services operate.

What happens if a bug in your modern, fly-by-wire car decides to mix up the gas signal and the brake signal?
(Almost) All car failures are perfectly safe if you assume they occur when the user is otherwise safe. It's the failures that occur in conjunction with other failures and run you out of safety margin you have to worry about.

Yes, this is how it will eventually happen for Facebook if they don't reinvent themselves (and they never do).

It doesn't even have to be that dramatic. People change and drift apart. The older you get, the more extreme the examples become. I often forget the names of people I once considered friends for life.

The more they pile up, the more Facebook changes from keeping in touch to unwilling voyeurism. The FB killer will be something that deftly handles change.
So you started this conversation with yourself because... ???
Yeah. I ride all year round in Minnesota. Either having a beater bike that's winter-ready or winterizing your regular bike is a must.

I have multiple bikes for multiple reasons: Long hauls, short daily commutes, exercise, and winter/off-road riding.

I also make sure to keep enough gear around for different conditions that may come up. Normally I don't ride with fenders, but if it's raining, I'll grab the winter bike, which has them and replace the snow tires. 10-15 minutes of work in the spring and I'm ready to go through the summer.

That said, I like the temporary hack here, provided it stays temporary (and is only done on bikes with disc brakes). Seattle doesn't get a ton of snow, so there's not much reason to keep studded tires around.
I'm not sure that I follow your argument about releasing more pollution and CO2 into the atmosphere is good for the environment.

The best way to reduce pollution and CO2 emissions is to stop burning fossil fuels, not resort to destroying farmland in order to find "cleaner burning" versions of the same stuff we've been using.
Congratulations to Eric and the Movity team! I'm working on a startup in the real estate space and Eric has been gracious in taking the time to give us advice and look out for us. I'm looking forward to seeing what they come out with.
I'm not in a brainstorming state of mind at the moment, but as for your initial point, it is true. I know of several people that hire people from the Pacific regions via Odesk to do content writing. Combine this with some decent SEO implements and your traffic should see a steady rise in 3 months.

I've recently left one organization for another. I was a Dev in a Cube for for several years. I now have my own office with a large window. It couldn't be a more pleasant experience.

I think with open plans you're sharing a lot more germs too. How many times have your co-workers came into work sneezing? Even in a cube farm, those germs just spread. At least with an office you can keep you and your germs better confined.
> Of course sooner or later, due to Moore's law and the way bitcoin works, the operating costs themselves will exceed the value of bitcoins mined. But that is years into the future.

That point depends on the value of the bitcoins too. What the exchange rate is for USD if you're paying for electricity in USD, or how much electricity you can get for a bitcoin if you are able to pay for electricity in bitcoins. (Which I guess has to do with the cost of electricity too, of course).

These are not predictable things. Especially, apparently, the value of bitcoins lately.

If you go to print, the fact that Adobe's tools understand multiple color models is a HUGE advantage over most other tools, which usually only work in RGB. It's not just open-source competitors, it's smaller teams trying to compete in this space as well.
Yeah I agree about it being something that's done because you enjoy it. Talking about what's an efficient use of time is so strange to me though, not to single you out in particular. It's like we're pretending our lives are so hyper-optimized that everything is a delicate trade-off. I spend a few hours here and there messing around with my setup because I want it to feel nice to use. It's not like I traded a couple hours of productive programming time for that. Sometimes I spend a few hours watching a movie.

For me a snappy editor experience, and vim in general, is about comfort, not optimizing for some theoretical top editing speed. I don't think I'd be a drastically worse programmer if I were forced to use windows notepad to edit code, I would just be more uncomfortable all the time.
I have two people in my close circle who made jump between medical profession and information technology and vice-versa.

[1] My cousin became a medical doctor and practiced for a year. He just couldn't disconnect himself from his patients sickness and that was causing him depression. Long term, he just couldn't see himself around sick people without becoming mental nut-case himself. He was very interested in Technology but couldn't see himself starting from entry level. He decided to go for MBA at a top 5 school. It seems not many medical doctors apply for MBA so it was easy for him to get admission. After MBA, he initially worked in healthcare technology consulting. He found his medical degree, Dr before his name and MD and MBA after his name very valuable since then in his career. Today, he leads healthcare technology practice for a major technology service provider and responsible for over billion dollar in revenue and P&L for his division.

[2] My eye doctor has graduate Electrical Engineering degree and worked for about ten years in development with SoCal defense contractors and NorCal technology companies before quitting to go to medical school. He is now a successful Eye Surgeon. While working in technology, he didn't like the politics of the workplace and overall work environment and expectations of technology companies. He has been very happy since becoming Eye Doctor and enjoys working with his patients. He still gets his technology fix by getting involved in medical technology innovations. He says his EE + Medicine qualifications makes him quite a desirable person in medical device industry.

It might take you a decade in technology to even get to the level of starting salaries of medical doctors. If you have high medical school debt, you may want to consider this in your decision to switch career.

You may benefit from your medicine background in a "relevant" technology company if you slide into the company at mid-level where you medical background is valued. Entry-level developer or IT person may not offer you any extra credit for being a medical doctor. Also in a non-medical technology company, you may be at a disadvantage compared to a person with CS degree with promotions and being taken seriously.

Unless you are interested in going to Business School, personally I will not recommend switching field from medicine to technology. You can always continue as medical physician while being involved with technology on the side.
haha :) I found that funny.

Have we all forgotten about a little book Joseph Alsop wrote?

https://www.commentarymagazine.com/articles/joseph-epstein/j...
I am 52, I started in BASIC programming in 1979. I am currently disabled and unable to work. I am trying to get better so I can become healthier and get back to work.

Programming became a lot easier when Visual BASIC and Delphi came out. Just drag and drop controls.

Due to ageism I am sure I don't fit the culture of a startup or relate to 20 somethings. They hire them young anyway not old. So I do tech support for family and friends to get by.
Makes sense. I am wondering about the protocol though.
