> Although the harm suffered on each trade is minuscule — fractions of a cent per share — the aggregate kickbacks amount to billions of dollars a year.

That's the money quote. 99% of retail investors should be buying stock infrequently, maybe once a month when the paycheck comes in. Ideally you're buying one or a few index funds, so the total number of transactions is small. If you're in that boat, this order-of-fulfillment tax really doesn't affect you and can be entirely ignored.

Your returns are really only in danger of being dragged down by this thing if you're executing many trades per day. But if you're doing that, you had better be a sophisticated investor anyway, or else you're definitely losing money.
You can get really good stability and precision using reaction wheels.
Depends on the country. In Sweden it's illegal to have certain drugs in your system. E.g. if THC is found in your blood you can be convicted for a minor drug offense. We're sadly pretty extreme with regards to drugs though.

I think it would introduce a huge amount of legal liability to guess that a drug would survive on a shelf for 10 years based on 6 months of testing. Especially if it's something critical like an EpiPen or cancer med.

At the end of the day, there's no really reliable way to speed up time, and it would be a waste of time to add 10 years to a drug development timeline just so you can leave it on a shelf for 10 years to test if it still works.

And yeah, we could probably go through and retroactively test some Ibuprofin, but also remember that these drugs are repackaged / reformulated slightly every couple years for various reasons, and without a lot of legal protections, no company will consider it worth it to guess about drug lifetime.
Glass isn't a consumer product either, it is just a dev kit.
I do not have that fantasy. I'm sorry if I gave you the impression that I did. I have communicated poorly somehow if that is the case.
That's basically my rationale for trusting Google with my data: They have both the means (lots of well paid smart people) and the interest (a substantial leak/misuse of my data could well be a fatal event for Google) to take care of it.

> In the G Suite contract, do customers indemnify Google from damages above a certain amount for privacy breaches?

I don't see how they wouldn't.
There's some truth to it though - the Windows Explorer file operations are flaky as hell.

I was just trying to copy files between an old system drive and a new one but I kept getting infinite recursion issues with the "Documents and Settings" (which is linked to Users) directory, permission issues, etc. Even as the SYSTEM user. I wound up having to learn a little robocopy for it.
With SEPA in Europe the victim of the charge back need to agree to it (in most cases at least, there are a few reports that banks did the charge back without asking). So traders should simply not accept the charge back. Payment methods which are easy to charge back like PayPal are not supported in Bisq.
There's no real problem at all to professional investors, they will figure out how to trade at the price they want regardless. It mostly hurts retail investors who rely significantly more on market signals to be correct. Professional investors almost prefer inefficient prices as it provides more opportunities for arbitrage against dumb money.
> I'm on vacation now and find myself fumbling with my phone to take snaps of interesting things I want to share way too often.

I just got back from vacation, and I agree. The whole process of taking pictures with my phone feels so cumbersome and annoying, especially for short lived scenes. It's locked and in my pocket for security and safety because I don't like to walk around holding my phone when I'm trying to enjoy the moment. It feels like I could either have the phone be an appendage and then have fairly easy picture capability, or actually be present in the moment but then it's substandard for taking impromptu pictures.

I wouldn't have as much of a problem with a dedicated device, as I wouldn't necessarily be as worried about breaking or giving someone access to the device that contains details about every aspect of my life.

Alternately, something designed to be an appendage but in an unobtrusive way (to the user, at least) might be just as good or better, as you suggest.

> Also with a few web sites I might upvote it first and then read it :-|

I can neither confirm nor deny that I do this too but I can say that I think it makes sense to do this, and I would go as far as to say that I think it's healthy for the HN community that stories get upvoted by people who have not yet read the story in full, as long as it doesn't happen too much -- while a story might turn out to be lacking or even factually incorrect in some way I think there is opportunity for interesting discussion to be had as long as the topic at hand is interesting.
Not really missing anything, but if you're willing to accept buying/selling 1% away from the "ideal" price, it's hard to complain about an HFT making a penny because you can't back-off when the market is moving.
Citizens don't have rights over every single decision in a democracy either. They elect representatives. Worker democracy could work similarly. As for why it is "necessary", presumably it would guide decisions so that the needs of the workers were taken into account, which very often doesn't happen.
Further if the ticks are say every 15 minutes it's easy to not disclose information on a tick boundary.

This is not true. Lots of things are happening in the world all of the time. You can't tell everyone to stop what they are doing every 15 minutes and wait for the stock market auction to close.
Don't know, but I do know that the SV model seems to be principally based around Ivy League kids who already have that kind of safety net in place.
Ask HN: Do you believe that Authy cloud backups are secure?
Authy looks like a neat service, and their blog post about the security of backed-up TOTP keys is promising, but obviously no one can independently audit the code.

Could anyone else weigh in on the security of this product, if there's any public information? Have there been any serious breaches or exploits?
This is a great idea. Helpful for those who don't know where to start.
You send fiat money to the trading peer using e. g. SEPA, OKPay, national bank transfer, ClearXchange and some other methods. There is no central bank account and Bisq does not control any money and can thus not steal any money.
That's a good question, but probably impossible to answer due to the US's peculiarity. From Wikipedia's list [1], it appears that the US is one of only a handful of countries with employer contribution. All of the others countries I could see are noted as using employer contribution as secondary, where a very large percentage of US coverage has employer contribution as primary or only.

Our brains do not use gradient descent. Last i read they use some kind of local optimization. Can someone elaborate on this?
Not really, there are lots of countries having "zero tolerance" policy laws which include ingesting and being under the influence of illegal drugs.
Is facial recognition creepier than recording?

If it's done in real-time, i.e. the scanned images aren't saved then surely a "This is person <X> you've met and tagged as X" is less creepy than actually videoing someone? You wouldn't get any information you haven't yourself added to the device (although it would probably need to lean on external data-sets for the training).

I wouldn't suggest facial recognition should recognise anyone you haven't met yet, I think that would be a bit weird (although I think it is the future anyway), but a way to effectively add a tag on someone you know would be great. Most people can do this without the technology to varying levels of accuracy and and breadth of their acquaintances.
The Linux version of Steam had one of these for a bit. People were not happy.
[I'm assuming you mean DOS FAT filesystems (FAT12, FAT16, FAT32) - anything else might be different]

> Wasn't at some distant time in the past deleting done by just renaming a file and changing the first character to a question mark?

That is just the entry in the directory listing - it would still walk the file allocation table and mark the relevant blocks as unused. The FAT operated as a collection of linked lists - the directory listing mentions the first block and each entry in the FAT states which the next block is for a file or 0 if it is the last block. Really a sub-directory was just a special file containing filenames and other properties so deleting an empty directory follows the same process. The root directory is a special case, being of fixed length (12 blocks IIRC) in a fixed position of the structure.

> I think that also applied to folders: Delete a folder's "file", and all the contents are gone, recursively.

No, you couldn't delete a directory with contents by default. Ordering a recursive delete would perform a depth-first search-and-delete on each individual object.

> Not sure how they found free blocks when creating a file though.

As the FAT had been updated, it was a simple first-empty-block search.

Unless something had deleted something just by editing the directory entry, in which case the blocks would be left alone as they would still be marked as in use. I did see this used as a way to try hide sensitive information without it getting overwritten, both as a naive copy prevention mechanism and a "hide my porn" technique.
What it's like to build products for women entrepreneurs
My point was that a mainframe could be a single point of failure, but it engineered to such a degree of reliability and availability, that this is unlikely to be much of a problem. Plus, you can cluster them, you can even build clusters spanning several data centers.

From a technology standpoint, I think they are amazing machines.

The problem, of course, is that they are ridiculously expensive, which is why "open systems" (often meaning PCs running Windows or Linux, but also proprietary Unix system) have replaced mainframes in many places. In a way, I think it is fair to say that Google did something akin to what you propose. (I am told, that proprietary software for mainframes is actually so ridiculously expensive that the already-ridiculous cost of the hardware is not that much of a concern, actually.)

As for the buzzwords, if you find a place where you are safe from them, send me post card, I might move there, too. ;-)
If you assume the second sentence explains the first, then this is correct - only websites (i.e something designed to be consumed by browsers) with HTTPS can take advantage of HTTP/2.
> earns about 100 million a year.

They made 147M in the first quarter of this year. 197M in the first quarter of last year. They might only make 100M/year after costs, but that doesn't represent the 600-900M they take from the market.
This is true, but incomplete. Such unsophisticated investor has to control his frequency of trading, and also the frequency of trading of his etf or mutual fund. Any fund needs to do trading, re balancing, etc. So there's a double layer where ppl get charged 'the vig'.
"Like many organizations we talk to, you probably have large amounts of data that you want to use to train machine learning models."

Honestly I don't know what I would prefer. certainly I would prefer more quality time with my doctor, but at what cost, I don't know.

Here at least (uk) yes. Al of the practices I've visited have strict 10 minute appointments and the doctor will cut you off at 10 minutes. If I go in for a flu jab(I'm asthmatic and at high risk), I expect to be in and out in about 2 minutes, and I don't see the doctor; it's normally a practice nurse that does it. You then get sent back to the aaiting room and told to sit tight for 10 minutes in case you feel weak, but that's it.

For consultants in hospitals it's different, though.
That's what the nutrition label for mayonnaise says, yes. It also says what kinds of fat. I didn't make this up, the FDA/Congress did.
> But neither Cantrell nor Dr. Cathleen Clancy, associate medical director of National Capital Poison Center, a nonprofit organization affiliated with the George Washington University Medical Center, had heard of anyone being harmed by any expired drugs. Cantrell says there has been no recorded instance of such harm in medical literature.

I am more than a little surprised by this. Fanconi syndrome, a kidney disease that can cause bone damage [1], has been repeatedly found in the medical literature to be caused by taking expired pills of the antibiotic tetracycline. [2]

That these people completely failed to remember these cases is distressing at best.

(I heard an interview with the author of this story on NPR Morning Edition today, and also scanned this story webpage. The only mention of tetracycline was by a web commenter on the story.)

i think bup does support concurrent access; the concurrent deduplication granularity is a backup set, so if two identical computers are backed up for the first time at exactly the same time you will not get deduplication - but that's inherently a dining philosopher kind of problem

Also, recent bup versions allow delete. No encryption IiRC, but you can examine it with git tools which is a feature on its own.
Well, I agree that it's not working out very ideally for us. This is why I think all those hyper-complicated trades don't necessarily have much real economic value, and banning them is unlikely to be very harmful.
It seems to pretty clearly be a rental, so no...
I'm not really convinced about metric system either. Sure, it has some nice properties, but it was created bit prematurely when science was really not developed enough to put solid foundations for a measurement system. It took some 150 years to make it somewhat usable (by establising SI), and even now the base units are bit silly. Now we are kinda stuck in the worse is better region because metric system is good enough and has almost impossible amount of inertia behind it.
What you have so far is really cool. But I want your second app to be a part of this.

After my note is written, help me compress it to the 4-5 word title, set categories, save and store, and I would definitely pay $5 a month for it.

Greg from Twilio here.

Not a silly question at all. Developers certainly have a propensity to recreate the wheel for the sake of recreating the wheel -- though I think that many of us would agree that the act of creating is itself the advantage.

That said, a few things:

1. Costs less. A Twilio phone number is $1 per month (in the US). A minute of calling costs $0.01.

2. You can get a new number any time you want.

3. You get to write code.

Don't want to speak for Marcos (though he happens to be sitting 10 feet from me at the moment), but my guess is that what excites him most about writing this post isn't that other developers will copy it line for line. It's that they'll use it as a jumping off point -- that it inspires and equips developers to ship their own inventions.

For an example of this, check out the folks at Burner app who used the similar concept (pre-Kotlin) to build an entire business around this idea.

How do people go about sending Link headers / configuring server push for resources with a changing hash in their filenames?

For example if you have your app.ab9a9a09fe9.js file, but then the next deploy you have your app.ba293dcde.js file... can you just set the resource to app.*.js somehow?
I've done PR for startups and this is one of the best, most detailed guides I've seen about how the sausage is made.

I would add:

Getting good PR in premiere outlets will give you so much more than just the first 1,000 customers. It can open the door to all kinds of opportunities, from being invited to speak at the conferences your customers attend, better recruiting, being noticed for partnership and business development deals, an being top-of-mind if you start looking for funding.

Embargoes are a tricky logistical detail, if you're using one, you don't want to leave any room for error. So aside from mentioning it in the pitch, also include something like "Embargoed until 4/13/17 at 8am California time" in stand-out font at the top of any fact sheet, press release, etc. that you share with the journalist and be sure to mention it in all your confirmation emails.

Once you get awesome PR, figure out the best way for it to live on your site going forward. I see lots of startup landing pages these days with logos like TechCrunch, Wall Street Journal, etc across the bottom but no links to said articles. I can understand why, for conversion rate optimization, you may not want to include the links on your landing page. But for ultimate credibility and (possibly SEO juice) consider having a separate section on your site for press where the actual links to the articles can be found.

My question is, which employers are on-board with this, and are they hiring?

> I think treating food preparation as equivalent to a Vagrantfile would really lose something along the way.

That's a neat idea, though, in a different direction. If you could implement some kind of standard recipe API and build a business around being a broker for commercial kitchens, wherein a customer inputs a recipe that follows a certain schema and an address, and the commercial kitchens respond saying either "no, we can't make that - we don't have the necessary ingredients / we're cooking at capacity / etc." or "sure, here's how much time it would take and here's how much it would cost." You would lose economies of scale found in most commercial kitchens, but customers would gain much more freedom over what they're ordering compared to pick-from-a-list traditional menus. Users could also search for highly rated recipes from around the world and see if somebody local could make it for them etc.
