I might be missing something here, but I don't think that someone being racist grants you the right to oust them. They don't owe you their time to review your work and at the same time you don't have to contribute to a project that you think is racist or any other reason.

What do you think gives you the right to demand inclusion?
All rendering is an attempt to solve the rendering equation which is very much physically based. Whitted ray tracing is doing a lot of simplification but path tracing (which is closer to what people are talking about doing in real time with new hardware) is a pretty principled attempt to solve the rendering equation via Monte Carlo methods. I don't see how that's not physically based. The definitive book on this stuff is literally called "Physically Based Rendering" https://pbrt.org/
On other services, when you request your data, they send it (with some delay) through a secondary channel (email, for example), which would prevent this attack.

(Yes, ideally services would collect less data, but if your account gets hacked they can access some data regardless)
Bingo. It’s the same reason marketers love the 15-34 demographic. They haven’t woken up to the bullshit yet.
I used to work at a healthcare company where about 1/3 of the development staff worked in RPG and COBOL day-to-day. A consultant came in to pitch them on a COBOL source control system, and from what I heard they had to spend most of the time explaining to these 60+ year olds what source control was before pitching the management on a 7-figure implementation for what was basically timestamped folders with copied of code inside.

When I left that company a few years after that, there was still no source control for the RPG or COBOL code.
Having worked on this personally, Deltamatic runs on HPUX & pretty much C++.

My info is maybe 10years old, but I doubt much has changed.

These infrastructure type things are incredibly complicated. Not in the “Newfangled” framework way, but rather the business implications of real world impact of potentially bad code.

I consider it one of the highlights of my career going thru the Delta Northwest Merger without shit hitting the fan. We were writing decrementer & while loops instead of for loops because there was a measurable performance & stability impact.

There’s something to be said about software that has withstood the test of time.

I’m impressed that the team is able to handle outages as well as they do. Having had some experience working with the folks at Delta & Northwest, I’d say they’re pretty impressive people. I’d be happy to steal some for my startup if they’d be willing to part with the flight benefits & tenure.

Full Disclosure: I was not a Delta Employee, but worked for a startup that built the checkin systems (which got acquired by NCR). I got to work with Delta as a client.
[MEMEX TEAM]

TL;DR; AMA about Backup/Sync functionality, ways you use Memex and we can make your life easier, the Storex layer described in the second paragraph, design methodologies and decentralization/Blockchain!

Hey there! I'm Vincent, a weird mix of software engineer slowly going service- and UX-designer. Since joining WorldBrain in February, I've been architecting and implementing parts of Memex's Cloud functionality, including Memex.Links and the Backup and Sync functionality that is currently in the works. On the technical side, I try to make sure that we can move fast and make the best trade-offs between ideal and doable solutions, so that we can create stuff that is as useful and easy to use as possible. But being in the field for 13 years building software, my main interest is shifting from programming, to the whole processes from reseach to designing functionality and communication strategies to make things that are as useful as possible, which I can then help technically architect. And as such, in my spare time I'm currently thinking about how to rethink web development to lower the barrier between designers and developer, reducing the write-test-modify cycle while taking a wholly new approach to QA that is driven by designers instead of programmers churning out unit tests.

Lately the bulk of my work has been battling AWS and Google docs, trying to get the Backup functionality to work as nicely as possible. But, in the process I've taken Jon's work creating the fastest in-browser full-text search engine currently available, and made it into a low-level library acting as an abstraction layer on top of different kind of data sources (IndexedDB, SQL, NoSQL, soon to come REST/GraphQL.) It still needs some work to be in a presentable state though (docs, more tests, etc.) The goal is, we aim to create many loosely coopled, tightly cohesive layers on top of it that solve common storage problems, like schema migrations, access rights, content feeds, live collaboration and moving data between front- and back-end. Due to it's origins in Memex, we called it Storex. Feel free to brainstorm with us on how to make this useful to lots of people and especially, what tedious problems you keep solving time after time hovering just above the storage layer.
Arguably the most popular podcast was Serial.
But what happens when we pass laws in our country that takes away the job in another when there is no realistic chance of them implementing some safety net to help? For example, when western countries put pressure on east Asian sweat shops to stop using child labor, they did, but the local governments didn't offer anything to help the children who depended upon those jobs to have enough to feed themselves, and as such many of the children transitioned into even more dangerous jobs or worse.

It would be nice if their government made up for the gap, but int he real world we have to deal with the possibilities they won't. So one has to deal with the ramifications of their choices that shouldn't and wouldn't happen in a good world but do happen in our world.
I believe it goes against most terms of service agreements with non-commercial isp plans.
What is atrial fibrillation, and why is your watch telling you about it?
Yes - but sometimes you don't have that choice. Would you rather not use a essential service(flight check-in or pay electricity bill) or disable the adblocker temporarily? To each its own I guess and tricky thing with pi-hole is, it is VERY hard to tell if website isn't working because of adblocker or because you are using Linux or it is simply broken.

In my college phonetics class, we studied spectrograms of various human sounds. The spectrogram of whispers is very different from normal speech - it almost just looks like white noise. Forget computers, it is remarkable that even the human brain is able to process it and figure out what words are being said.
I've been wondering about this for a while. Especially now that they're actively supplying servers to support sync (which also at least at the time of writing doesn't seem to allow running your own server).
I could definetly see a world where a device like this fronts your home router and is zero config. Maybe a “super” router?
> they are actually paying $0

Nope, they have to pay transport to the peering point (or own it).
I just wanted to say, thank you for this. I was beginning to wonder whether anyone in the world cared.

I’ll be running a series of experiments over the coming week to test how ruthlessly a ban curtails someone’s ability to speak. Dan’s hypothesis is that this “probation” isn’t much different from normal HN: users vouch good comments, so why not write good comments? My hypothesis is that orders of magnitude fewer people will read them, so there is no point.

I’m also dusting off my old HN clone, Lambda News. Watch for https://news.ycombinator.lol within the next month.

The idea is for it to be a real-time clone of HN’s stories. That way people can switch news.ycombinator.com to news.ycombinator.lol and then say whatever they want.

LN’s rules are identical to HN’s (and we’ll be enforcing them just as effectively), but intellectual curiosity won’t get you a visit from the Stasi.
He tried to do what he thought was right and lost. Then tried to maximize the cash per his agreement and lost. So he did the math and realized that he could spend a chunk of his life most likely either fighting in court and/or being made miserable in exchange for a sum of money he absolutely didn't need. I think he made the right call given his situation. Though this should be (yet another) cautionary tale: when you sell your company, the deal is that you are giving up control in exchange for cash/stock. You can generally stand either on the moral high ground or a mound of cash, rarely can you do both.
1. Yes, light is always 3D but the description in popular science is always simplified. Also experiments usually measure along a line across the screen and don't build up a 2D pattern on the screen that you usually see in popular science. For instance Fig 4. here [1] .

2. Because the light does not diffract up and down too much, only horizontally. So, for instance, the light emerging from the middle of the left slit stays at the middle level and does not interfere with the light emerging from the bottom of the right slit.

Imagine looking somewhere on the screen at middle height where the path lengths are so that its a dark point. The light here is coming from the middle of both slits. Now move down a bit. The light here is coming from the bottom of the two slits here, and the path lengths are still the same. So you still get a dark point. I hope this makes it clear.

Internet commerce didn't go away when the first dot-com bubble burst.
We've also long since passed the point where games have pre-rendered scenes that could have been rendered in-engine on high-end hardware.

The only tip-off I had that (some of) Nier Automata's cutscenes are pre-rendered was the drop to 30fps...
True! But a similar debate has played out in the mammography space. While routine mammograms have undoubtedly saved thousands of lives, some researchers have concluded that the complications caused by false positives (e.g. infections after a biopsy) may make the net contribution of routine mammograms negative. In other words, any individual is more likely to be harmed by routine mammograms than helped.

I'm not saying that the healthcare features in the new Apple Watch are bad; just that it will be interesting to see what their net contribution to healthcare will be.
You're either very young or naïve or both. Almost everything we do in this world has good/evil direct/indirect consequences. For example, should I blame you for polluting the planet because you are using an electronic device to post naïve comments on the internet that likely gets its energy by producing some sort of pollution? What about the vehicle you drive? What about the slaughters that take place because of your meat consumption? What about the carbon dioxide you breathe out that's toxic in high quantities? How dare you add to our carbon footprint!

In the end good/evil are myths. They are human constructs and they can change depending on time and place. Ethics is not a hard science and your belief that something is good does not make it a fact.

The military can cause a lot of destruction and grief around the world, no doubt, but it can also cause a lot of good and stability. In the real world there will always be "winners" and "losers" An action that benefits you may directly or indirectly hinder someone else.

Our military's mission is to defend our country and that means that sometimes other countries will lose if they decide to engage. Inevitably there will be innocent casualties. This will never ever change. It is an honorable thing to do what we can to minimize it but unrealistic to expect it to ever go away.

You will likely see the world in a different light the older and more experienced you get. You're not a good person. You're not a bad person.

You're just a person.
That's a good point, and it immediately makes me wonder what kind of e.g. camera and monitor might be enough to enable remote synchronization between brains. There are so many options. You could transmit signals carrying things like pulse and breath rate as well as visual and audio.

My sense of urgency comes from my desire that folks reading this on HN realize that the "magic sauce" is in the brains not the comm channel.

I've been trying to get traction on this idea for years: if you want a mind-machine interface you keep the hardware simple and let the most advanced processor do the tough part of the job. (In case it's not crystal clear, the most advance processor in ANY technological system is the one between your ears, eh?) Metaphorically, the hardware should be seen as one of those cheap, dumb modems that offload most of the work to the CPU on the motherboard.

With a little bit of hypnosis and the crudest of GSR (galvanic skin response) sensors you can make a brain-machine interface at home that would blow your mind (not literally.)

Anticipating the next question: "If it's so easy why isn't everyone doing it?"

Well, smart-alec, it's because it requires a major adjustment of one's self-image, that most people can't handle or even imagine, so (for example) it could never become a mass-market consumer product.

We have had the technology for decades. The limiting factor is belief. That's why this "BrainNet" is exciting: not because they used such a crude interconnect, but because they did it in a way that opens a wedge for the idea that this stuff is possible at all. As soon as you grasp that the doors fling open to all sorts of fantastic possibilities.

(And pitfalls: you and your brain are not the same thing and will occasionally find yourselves working at cross-purposes. At times like that you'll probably NOT want your brain to be directly wired into your "smart" home and have all your passwords, eh? Like I said, this requires a major adjustment of one's self-image.)
It's not only a matter of telling "this was a whisper", but also of actually recognizing what in the world did you say in that whisper, no?
Launching in M71 (i.e. delayed by a single release) would remain consistent with the Google statement.

The statement applies to any delay within the range of "soon" and "not forever".
As an American, why does every topic turn into a jab from the other side of the ocean? Particularly when some of those places there are overrun by surveillance and the heavy use of cell phones. We're all in this together.
I don't think he's saying that blockchain is required to solve this problem, just that even with blockchain, the problem is not solved.
If they are occasional, standard international calls aren't that expensive anymore. Telegram has voice calls too, fwiw.
Be careful what you wish for. I'm not sure native advertising is something we should be wanting to see a lot more of.
Great point. I should have focused on false negatives in my original comment to make my point. Thank you!
Exactly why I made the conscious choice to use the word "likely". :)

How Image Recognition Can Improve E-commerce
I have a similar issue. I use 'keyed' email addresses, in my case the domain is contained in the address (myname_domain@mydomain.com). This is an included feature in many mailers, even google supports it youraddress+key@gmail.com. Anyway, it won't work unless Firefox Monitor supports wildcards.
It occurred to me also that you’d have to include trust, a la digital signatures as part of the solution also or the whole discussion wouldn’t make sense. If the block chain network actors aren’t trusted it leaves too much room for malicious behavior on the block chain itself.

I also wonder how efficient it is to “query the block chain”?
Agreed and I think the high production podcasts are definitely hitting a bit of a bubble. But my favorite podcasts are ones that always have different guests and I think that category has a lot of growing to do. The expertise required for the guests is only the one they already have. For example a nutritionist just has to come on and talk about nutrtion. Something they do for daily anyway.
SF and California at large is run by liberal Democrats, but that's a far cry from actual leftism.

Yes, we should require them. The WhatsApp founder didn't attempt that, he just hoped they wouldn't.
Very few people love the US' meddling in politics. If we have good trade deals, presumably those were made by our politicians deciding they are alright. We can have opinions about that, but they are separate from this issue. This is the US trying to bully the EU into doing what they want, which is something that should be opposed.
What’s atrial fibrillation, and why’s your watch telling you about it?
I feel the same way. There's been a few HN threads where everyone chimed in with "here's how I use mine" and each time I read with great interest thinking "These are the people that are going to teach me something new! Something I've been missing because this thing doesn't seem all that useful to me" and I never learned everything new. I don't get the appeal at all, it's the time savings seem to be measured in seconds, and the convenience seems to be so marginal as to be not worth it for me.
The issue is that trust breaches can't just be rolled back. You put people in a situation where they don't want to get caught out by the next change that the press doesn't pick up and/or you don't hear about.

Just checked, you are right! The issue was actually that it focuses the tab when you open it, it does not open it in the background. I have clarified the comment, thanks!
Now, this would be a thing I'd get excited about - if a non-profit company gets behind developing it. It was a given that whoever bought Skype would milk it for the money.

Imagine an App on every platform/device that forms a mesh amongst its users and communicates short messages in a P2P way. Perhaps some simple state could be stored in some special nodes that aid in co-ordination. The whole thing may come with a Wikipedia like openness goal. I'd donate generously for such a cause.
Announcing the web-sys crate
The reason it's VERY labor intensive is because in a PoW blockchain, each block also includes a value that combined with the previous blocks hash hashes to a number less than the difficulty (the value labelled nonce in this demo).

The difficulty can be adjusted to ensure that finding such a number is very hard. Obviously in the demo, it was not so very difficult - your machine was able to work out a value for the nonce very quickly by itself, but in the real network, the difficult is set so that this is hard. So hard that the whole network of miners working together will only find one, on average every x minutes (configurable depending on how you update the difficulty). This means that creating another block is difficult.

The whole network has the rule that longer chains of blocks are preferred over shorter ones, so as more blocks are added to a chain, the amount of computation required to overtake the main chain and have your modified chain accepted as the truth becomes very large. To rewrite history, you don't just need to modify the data and recalculate the hash for each subsequent block, you need to find a nonce that works for each of the subsequent blocks, and you need to be doing this faster than the main chain is adding new blocks, or your chain will never be as long as the main chain, and it will never be considered the 'truth'.

That's why people talk about 51% attacks - the idea is that you need to have a majority of the hash power of the network working on your dodgy chain if you want it to overtake the main chain. Now there are things you can do with less than 51% of the network hash power, but for the naive approach, you're going to need a phenomenal amount of computing power to stand a chance of having people accept your version of history. For alt-coin chains with very few participants, there have been real attacks along these lines. It's hard to imagine attacks like this succeeding against any of the main blockchains though.

And yes, comparing two blockchains for equality is very easy - the hash of a block includes the hash of the previous block, as you can see in the demo, so the hash represents the entire history. If two blockchains have a different hash for the top block, they have different histories.

This is silly hubris. Facebook seemed like a "shitty" project before it was a multi-national conglomerate.

Crappy? I was seeing a physical therapist for a while, he'd strap a heart monitor around my chest and have me doing exercise. When I got my Watch, I’d sometimes compare the figures — they were never more than two BPM off.

Maybe that's not precise enough for doctors, but "crappy"?

My best career decision was to leave microsoft for a smaller company. Back then, there was a toxic culture at microsoft due to the dog eat dog review system they had in place.

Let's say I'm the buyer and this happens. There's now a record on the government blockchain that says I own a yacht. Does that mean I physically have possession of the yacht now? How do we assure that what's in the blockchain is an accurate reflection of who actually has physical possession of the boat?
This is not poverty. It is "extreme poverty", very different thing.
Fortran predated APL by 5 years and that had actual function names (even if they were limited to 5 characters to fit on punch cards). I'm not sure what your point is.

My comments ( I am experienced in using spark, so could be biased): 1. as the worker machine as 16 vcpu, and 122G ram, setting spark.executor.memory to 8GB seems too small, I would be interested to see how it works with 32GB setting per 8 cores. 2. CDH is not so updated with spark releases, new spark releases 2.3 can be used together with CDH hadoop for test. 3. in table 4, spark is the only system without fails, which confirms it is a very robust system. 5. It is a performance test, but is the result verified?
