Ask HN: What are the performance costs of Docker?
I am really curious since the world appears to run on Docker and yet, there isn't much information out there. May be I am bad at searching, there is a ton of blog spam. Google search yields the top SO answer: https://stackoverflow.com/questions/21889053/what-is-the-runtime-performance-cost-of-a-docker-container

Which references a really old IBM paper: http://domino.research.ibm.com/library/cyberdig.nsf/papers/0929052195DD819C85257D2300681E7B/$File/rc25482.pdf

I would have thought since millions of developers use Docker, there must be hundreds if not thousands of high quality benchmarking results and optimization discussion for dockerized workloads and how they compare with native performance. Why aren't companies and developers not interested in benchmarking Docker? And how come we never talk about it too much on HN?

Google Image search yields a few more graphs, one of which led me to this article: https://www.scylladb.com/2018/08/09/cost-containerization-scylla/

Performance impact straight out of box seems significant.

Ofcourse, with any performance discussion, there is always "take results with a grain of salt" and flaws in benchmarking process. But, I am just generally curious about the following:

1) Has your company conducted docker performance tests with your specific work load?

2) If yes, what is the performance hit approximately?

3) If no, is it because AWS/cloud resources are cheap and it is not worth the time or is that no one questions it?

4) Is the ease of development preferred vs. cost of performance in terms of ROI?

Thank you.

PS - Does your company not use Docker? Why? Would love to hear that.

> Better to have something both open source and open network like Matrix

I love Matrix, but non-technical people don't care about these points (I do, though). Matrix needs to have a better official client than Element at its current state before I think it's even worth looking at becoming mainstream.

(I run a Matrix homeserver for myself with literally all of my chat communications going through it)

Edit: my comment sounds super defeatist, I want to clarify that my hope is that Matrix can become something I can recommend to anyone
If a tiny bit of undirected evaporation is enough to push the fragment to deorbit, it's already so low that it would have deorbited on its own very soon anyway.

In that case evaporating it completely would be a better option, as a gas it's harmless
I don't believe your friend†. I work downtown, as does my wife and son. I've been mugged (not carjacked, just mugged --- and not in the Loop!) and had the police catch the assailants within minutes. If I got carjacked, I have a very high degree of confidence in the police response I'd get. But if I was a Black teenager shot in Lawndale, I would have zero confidence.

† Except to the extent that the police won't give chase in Chicago, just like pretty much every other major city, since police chases were killing innocent bystanders on the regular before they were essentially banned everywhere.
You do own the device. You can jailbreak and install whatever you want.

The payment grants you software access to system calls that are blocked by apps installed from the AppStore and has nothing to do with the underlying hardware.
There's a few dozen nuclear powered RORSATS. When their start leaking (due to micrometeorite strikes or just wear & tear), they leak out globs of coolant that coagulate together. Each satellite has a few hundred points of coolant, which can make a LOT of 1cm across globs (or larger globs, or droplets that are too small to detect). I don't have a paper handy, but IIRC these droplets were the #1 source of space junk up until the 2007 antisatellite weapon test

> Now, an L2 service could go lower but then they're taking on more risk which they'll want to be paid for and it's basically reinventing Venmo or Square Cash.

It feels like there is a subtle misunderstanding here: Credit cards are at least L2 systems, not L1. Physical cash, the foundational raw-unit-of-account layer most comparable to Bitcoin or Etherium, is the L1. Something like Venmo or Square Cash would be L3, built on top of the credit networks or electronic bank transfers which are themselves a layer of abstraction over transacting in cash.
How would one slice a byte array without magic numbers? Or without constants representing said magic numbers?
Cybersecurity Incident at Uber
If they really just wanted to avoid taxes, there are ways to do it where they’d keep way more than 2% of the company. And with all that saved, money they’d still have plenty of political power. Is this the best of all possible outcome? Maybe not. But it’s a lot better than the estate planning of basically every other rich family. You’d think we’d try to encourage more people to do it.
I thought it was April for a second there.
McDonald's is ostensibly committed to social justice?
This makes a false equivalency. Petition in traditional finance is with regards to individual transactions. In crypto, petition would be how the protocol works. The equivalent in traditional finance would be the credit card EULA, rules and conditions. Small players definitely have no redress here.
The problem is that they’re competing against even cheaper air fares.
I get an impression it's close to direct competition to their console UI. I wanted to see a gaming UI like that that's fully open source.
Yes, I don't disagree with anything you said. I am not saying MFA may not have at least slowed down the threat actor but the focus here should be how easy lateral movement was. Like you said there are many ways to get in. If the network share was treated the same as internet facing stuff though, that sounds like a deeper issue many orgs face but I am surprised that a fairly new org like Uber is not doing that already.
I didn't know adobe was so hated. They're still my best example for software making. I'm not a designer, and three times in my life I've had design needs that I tried to solve using free (as in beer) software, and it just never worked well. Adobe always just worked and fast.

First time was a book that had to be made ready for publication quickly (InDesign - my intro to paid adobe software), second time was 4k video editing (here I truly tried so many alternatives, free & paid), third time was basic motion graphics (after effects is brilliant and easy). Their software costs a lot of money though -- maybe their payment plans are what have made people bitter. I dislike the plans too. Maybe I came to adobe late, but I love their software.

Out of all the shady organizations that charge my card when I don't expect it, I mind adobe the least.
Unfortunately I don't think it's practical to wait thousands-millions of years for everything to decay
I visited a museum exhibit once in Amsterdam called, "Torture Instruments Throughout the Ages". It's unbelievable what human beings can do to each other. The "Wheel" was one. Most were fairly simple: being locked in a cage, or pushed down a hole, until you died of starvation and thirst.
That's some circular logic right here, mate.
What? If it was paid to take it'd be absolutely wasted. Bernie Sanders needs another mansion, it isn't going to pay for itself. Gotta hand those kickbacks out.
There's no reason to believe AI or any other automation displaces human labor (esp in a way that causes unemployment). And even less reason to believe it already has.

https://noahpinion.substack.com/p/american-workers-need-lots...

It seems to be a myth caused by anxiety about high unemployment in 2010, but we're no longer in that world.
Technically true, but most countries make much greater use of VAT than the US does of sales tax.
The article lays this out pretty well I thought?

They avoided a ton of tax if they had sold the company or even passed it to their heirs.

Instead, they created a couple non-profits, special ones that can make unlimited political donations, then put their family in charge of the non-profits.

So while they don't retain ownership, they retain control and are able to direct the company's money to their own political causes, all while saving on a $700M tax bill.

I mean, that doesn't seem that "altruistic" to me?

HN seems to be the first to say "paying your taxes is the right thing to do for society".

But these guys get a pass when they avoid a $700M tax bill and get to continue to use their billions in wealth to influence politicians?
Some of these problems could be solved by having frontend validation on a number input.

Regardless, I think the award for worst input goes to "datetime-local". The MDN page for it even says "Because of the limited browser support for datetime-local, and the variations in how the inputs work, it may currently still be best to use a framework or library to present these, or to use a custom input of your own". Followed by the date and time inputs, which are a real pain to work with.
Can you recommend a book that you think presents,say, calculus, significantly better than the books commonly in use?
Is stopping Purdue Pharma from selling life-destroying opiates "clamping down on little people"? I'd say no.

Is alcohol and marijuana prohibition "clamping down on little people"? I'd say yes.

Clearly there are shades of grey here that need to be worked out and there's no substitute for a first principles analysis of each case on its own merits.

If you are worried about the unintended consequences of prohibition, then there are many other avenues without that downside, such as taxing fast food and using that revenue to subsidize healthy food, or mandatory packaging labels, or public health education efforts.
Best command-line-only video games (2019)
Is it possible to replace LG's webos with this,after rooting it?
Chiming in because we have an open source game engine on Saito (https://saito.io/arcade) which imo is the future of crypto gaming but is usually overlooked by people who want to talk about crypto gaming because what they want to talk about is tokens and speculation rather than actual games.

If you check out the Arcade you'll see there are lots of fun games - my personal favorites are Twilight Struggle, Poker and Red Imperium. You can do things have encrypted peer-to-peer chat and video channels while gaming, and all gameplay is provably fair.

Agree there is a bias in media coverage, but it's not because there isn't fun stuff happening and is more because of selection-bias towards talking about speculative assets and token speculation. Also not a tremendous amount of overlap between people who actually play games and those pitching breathless articles to tech media.
It would be hard to achieve unless it was somehow necessary to connect the TV to wifi in order to use it at all (even when something is plugged into a port). That would be pretty confusing for people I think.
The speeds involved make ever piece a bullet and it is impossible to fully plan for that contingency. The best option is to aim it to the atmosphere or a debris zone. Especially when something unexpected happens.

They already do most of this for US and space partners, but it also adds significantly to weight to do it for every single small piece and parts naturally fall off.
Docker is not a virtual machine.

It's basically chroot.

And what do you think the performance impact of chroot is? Not much.

About the only significant impact would be on networking - which is often virtualized in docker (especially k8s). However as external I/O is orders of magnitude slower than how fast things happen inside a CPU this would rarely matter.
> One of its modules attempts to translate natural language requests into the correct shell commands and syntax. For example, if you typed “compress Documents folder,” CLAI will recommend the corresponding Tar command.

This is such a bad idea I don’t know where to start. Shell commands are a dangerous, but precise tool, somewhat like using a scalpel or a surgical tool. Dumbing it down so it can “guess what you want it to do” is going to result in more people (Specifically people who don’t bother to read the docs) breaking things.
It may be easier for a smaller company to be secure. Usually people are the weakest link.
I thought the money going to the 501(c)(4) isn't deductible? edit: ah nvm, this is focused more on them not paying cap gains since they didn't sell anything
Heavy clickbait to generate outrage. The Chouinards are the only ones who actually acted in any real meaningful way towards the Giving Pledge.

A better article that is more about the facts: https://www-nytimes-com.cdn.ampproject.org/c/s/www.nytimes.c...

[..]The Chouinards then donated the other 98 percent of Patagonia, its common shares, to a newly established nonprofit organization called the Holdfast Collective, which will now be the recipient of all the company’s profits and use the funds to combat climate change. Because the Holdfast Collective is a 501(c)(4), which allows it to make unlimited political contributions, the family received no tax benefit for its donation.

[..]

“There was a meaningful cost to them doing it, but it was a cost they were willing to bear to ensure that this company stays true to their principles,” said Dan Mosley, a partner at BDT & Co., a merchant bank that works with ultrawealthy individuals including Warren Buffett, and who helped Patagonia design the new structure. “And they didn’t get a charitable deduction for it. There is no tax benefit here whatsoever.”

[..]

“This family is a way outlier when you consider that most billionaires give only a tiny fraction of their net worth away every year,” said David Callahan, founder of the website Inside Philanthropy.

“Even those who have signed the Giving Pledge don’t give away that much, and tend to get richer every year,” Mr. Callahan added, referring to the commitment by hundreds of billionaires to give away the bulk of their fortunes.[..]

I'm lucky enough to have met Tom. So much of his writing and online persona made a lot more sense to me having had that experience.

He's a really excellent person, and I'm glad he does the things he does.
interesting article, there is so much more to illuminate from that than just scrutinizing women's choices with curiosity and disdain, I think it is also illuminating to look at what men learn:

the intimidatingly attractive woman has the same social anxieties as the woman in the bottom ten percent. the person that's beautiful on the outside, is also beautiful on the inside, despite many woman in the bottom ten percent relying on the "inner beauty" becoming their whole identity and sales pitch. the income isn't interesting and barely a factor at all, the marketable skills to potentially generate income aren't that interesting (but a common interest might be), the education to potentially generate income isn't that interesting serving only to change the social circle to meet potentially stable partners with economic prowess. so its deduces to men continuing to just try for the more visually/sexually attractive person.
Could have sworn there was a thread on this a while back on how most of these torture devices were not used a lot and many are exaggerations for the sake of being dramatic.
Right; the first part contradicts the second part and I’m not really sure what you’re advocating for as a result.
When do you get the money at y-combinator?
When do you actually get the money at y-combinator? Is it immediately after you clear the interview. Or when the batch starts. Or after the batch ends. What is the actual process. Does the SAFE come in a mail. Do you sign and mail it back. Is it online like DocuSign. Do you get a check mailed to you. Do they wire the money
Let’s talk about your lifestyle instead.
By having an API that abstracts the details away, like any other browser API. I would expect something like attestationObject.getPublicKey() versus whatever is going on in that demo.

I believe it was some part of oauth or saml (again not an expert here) where developers were making a common mistake by not verifying everything in the spec, leading to an easy bypass if you knew how it worked. Having devs implement a complex spec relating to authentication is a recipe for disaster.

McDonalds and other companies do wage theft because it's profitable. Having to pay out a couple of times whenever someone raises a fuss is already paid for by all the times someone didn't notice. Unlike violent crime it affects nearly all of us directly and represents a larger monetary value than all burgarlies and larcenies put together.

"The convoluted wording of legalisms grew up around the necessity to hide from ourselves the violence we intend toward each other. Between depriving a man of one hour from his life and depriving him of his life there exists only a difference of degree. You have done violence to him, consumed his energy. Elaborate euphemisms may conceal your intent to kill, but behind any use of power over another the ultimate assumption remains: "I feed on your energy.""
- Frank Herbert, Dune Messiah
There's not much of a story here.

He's making it a non-profit effectively, so he's not going to be personally getting income, and therefore no tax.

That the family controls the non-profit is one thing, but they're not going to financially benefit from it in a significant way.

I mean, their airfare and hotels are going to be paid forever though ...

This is just taxes in a straight forward way: profit/income = tax, otherwise not. His kids aren't getting the assets, so no generational tax.

It's just straightforward as one should expect it to be for the most part.
Record fine for Instagram following EDPB intervention
Or even have a separate attribute to indicate that it only allows integers and maybe one to enable/disable the up/down buttons.
The issue with real life is 'approach anxiety' and now that online dating has been out for a while - people are not as open to cold approaching as they used to be. The default has shifted. Further more, it's hard to tell if someone is single, or even open to dating - this leads to many more rejections.

The only good thing about online dating apps is the anonymous liking feature, you get match when you mutually like each other - so on paper there is less rejection. However as this thread states - it has other downfalls.

This issue really got to me few years ago and I set out to build an app that would allow you to have this anonymously liking but at events, bars etc
So it's hyper localised, you check-in to an event/bar and you see other singles that are there. If you match, you can then 'warm' approach them.

I always just saw this app as an ice breaker app - it was received well by my peers. Unfortunately due to flaky business partners and covid, i'm only now at a point where i'm ready to release. Pending Apple app store approval which has been an absolute pain.

It will be a slow roll out, initially in Bali, Indonesia. Pending response and funding.

If not selling the company and therefore not having to pay tax on the sale proceeds that you would have made is tax avoidance, then so is sitting on the couch instead of getting a job.
Users include both buyers and sellers.

Slow settlement and reversible transactions are a boon for buyers (and for fraudsters abusing chargebacks to get free stuff). For sellers they're a bit of a nightmare since you never know when money you thought you had been payed in good faith might disappear from your accounts with little or no recourse.
I would hope removing food that is causing violent crime, is a net positive enough that the little people would prefer it.

Of course there is no incentive to hurt the poor, the debate is over what is the correct way of helping them.

Saving a few bucks on a big mac meal, in exchange for their health and crime, may not be the best way forward.

From a non-us perspective it's a bit odd that a CEO has to point out that violent crime is happening too much, that it's bad and that something should be done about it. That's the gov's job?
> Would Britain really say “it’s ridiculous. Things change. Move on” for forcefully castrating Turing simply because he was gay? Oh wait. No. They didn’t actually do that.

And what did that do for Turing? He's still castrated. He's still dead. Were the people who apologized even the ones responsible? They must be mostly dead now too. Was there any serious concern in 2009 when the apology was issued that the UK was going to continue castrating gay people?

That had far more to do with present day politics and empty gestures to appease people like yourself than with making any repairs or apologies to anyone, not that such gestures mean anything to dead people anyway.

The people who used to own the diamond and could theoretically have any rightful claim to it are likewise dead, as are the people who stole it. It is where it is now and moving it somewhere else won't change the past. India's economy just eclipsed the UK's and is on the rise, while the UK is declining, so they'll have the last laugh anyway. Maybe they can buy it back at a yard sale when King George needs to pawn it to pay the rent on Buckingham Palace.
> It's a special kind of privileged to be able to yell "Shut these places down that serve unhealthy food." without first securing healthy food for those in need.

Special kind of privileged? I moved from the Bay Area to Vietnam. I've lived and traveled all around SE Asia for many years. I've seen the poorest of the poor, in the most remote places possible. I've eaten the same food. One thing they have going for them is that food is inexpensive and food is available. It is also not fast food.

It is possible to feed people food that isn't crap McDonalds. The concept that it is the only thing available, is completely manufactured. The fact that people give up production of good food, for this crap, because it is cheap and easy, is a big part of the problem.
I 100% started reading that entire article until I remembered how I got there and snapped out of it. I love it.
> Whats wrong with requiring a GPU?

I'm glad that you never encountered this before and I sincerely wish you never will: getting on call 3am in the morning due to server outage and you couldn't diagnose remotely. You rushed to the server room, which was only 50F btw, connected to the machine and brought up a rescue shell. Oh, did I tell you that none of them has integrated GPU?

See, it's not about the time you sit in front of your M1 MacBook and have a nice cup of tea -- it's about the situation where everything goes south and your tools and infrastructures can still have your back
They sell an API product, of which documentation is an absolutely core, user-facing part of their product. It doesn’t make sense not to own something that differentiates your products value proposition.
If it's the case, perhaps it makes more sense to block based on chargeback rate (that's actually what payment processors are doing) instead of blocking on nature of business?
In defense of portion sizes, in the US it is a cultural thing to not finish your portion at restaurant and get the rest packed up for the next day. That explains the double portions
