I've been looking into payment services lately and it looks like very few have pricing schemes that work well if most of your income consists of micropayments of $1-3 or less. Stripe's pricing seems to be fairly standard, so I'll use it to illustrate my point: the fixed 30c cost on a $1 payment is 30%, which seems prohibitively expensive for this use case.

The only pricing scheme I've found so far that works adequately for my use case seems to be Paypal's Micropayments pricing of 5% + 5c: https://www.paypal.com/ca/webapps/mpp/merchant-fees

Although I've heard enough horror stories about Paypal on the merchant side that I'm a bit hesitant to rely on it as my only payment processor.

I'd appreciate it if anyone here can share their experience with handling micropayments and the services they used to process them.
This articles doesn't acknowledge where JWTs really shine: Authentication across a cloud of services, esp. a microservice architecture. JWTs allow a session to be shared across all of the services without any shared state.
How does the GPL gag developers?
That depends on the ears, that's why the ultrasonic youth drive-aways are so successful. Old people simply can't hear them due to age and external degradation (loud rock music concerts).

I, for example, can hear these ultrasonic weasel defenders, which operate between 20 and 30 kHz, again - when I used to work on outside construction works using massive jackhammers, excavators etc. I couldn't because daily stress would fuck up my ears.
This remains a solved problem. The location phrase specifies the coarse location. Additional addressing information is used to introduce granularity. Look at how addresses are conventionally written already, and in a good chunk of the world, the addresses are written top to bottom, most specific to least specific. The largest remaining problem is that the location mapping depends on a proprietary database, but this is a common problem (in Canada the database of postal codes is also proprietary).
But Photoshop!
I'd imagine the implementation will show up in the next appropriate XNU kernel release.
"column store technology as pioneered in MonetDB" ???

wtf? MonetDB pioneered column store technology? what else have they pioneered?

This wouldn't remove foley, it would just replace the humans doing it with computers.
I love the news maps ui it's beautiful and so much more intuitive. It was really confusing before even to me: a techie!
Just like he said, that involves touching the screen and opening a menu. There's no predictable way to immediately silence your phone.
The fact that anyone can do anything with Siri is a HUGE opening from what's deployed now, where Siri can open your app by name and that's it.

Now there are defined integration points that are open to all developers.

It's not 100%, but that's not Apple's way. Even if they go there they do it a step at a time.

This is still a huge improvement for users.
I would leave it as close to stock as possible and make sure it has the latest security updates. Turn on FileVault and make sure she uses a logon password.
"Just hire developers who are smart enough to learn whatever language you are using."

Knowing a less-commonly-used language like Haskell could be a fairly good indicator for this quality.
The point of encrypting the base system image is mostly to make it part of the Secure Boot chain. rootless is a policy control to stop processes from modifying the OS from inside. An encrypted system image stops things with hardware access (but not the unlock key) from modifying the OS from the outside. You can trust any disk whose blocks you can decrypt with key X, to have been only written to by someone with key X.

Exactly, most of the work here is video processing - analyzing a portion of one video, then finding another video clip that has similar characteristics. Then they copy the sound from the second clip into the first clip. But they could be copying any metadata, not just sound. This isn't really about sound _at all_.
Huh? Apple lets me use my own email address, unlike say, Google.
Memory addressable non-volatile storage instead of SSDs that process block storage read/write commands, and file-system improvements to allow direct mmap of file contents from NVM into your process address space without copying through RAM.
It'd have to be ongoing, I think. It's probably not as simple as a few lines in a comment on HN, no, but is a blanket ban on something potentially useful a good idea, just because it's simple? My inclination is 'no'.
> And I wouldn't bet on that since Microsoft surely sent a big team of their brightest cookies to make a valuation of the company.

By that simplistic reasoning no big company would ever make a mistake.
Moxie has always been a huge dick in this regard. I have no respect for Signal because of his mistreatment of the open source community.
Well there's a surprise.

Perhaps the videos aren't reachable via his work network, or the OP doesn't want his "work" to know what's being viewed at the office? I'm sure there are other reasons to use a cell network (which is the assumption).
> basic problems understanding logic and execution flow

I don't disagree with this. My point is that layers of obfuscation on top of the really difficult bits only make it harder to devote attention to the difficult bits. Beyond a certain threshold, beginners throw up their hands and walk away, especially if they're motivated only by curiosity (which seems to be the target audience of this app).

I know I reached this stage as a teenager when trying to learn C++ (because I wanted to make video games, you see, and everyone told me this was the only language to use), and trying to perform even the simplest operations was piled under layers and layers of seemingly-arbitrary nonsense. I gave up and didn't touch C++ again until after college.

In all, I think there's survivorship bias at work here. We say that these things aren't a problem, that they aren't barriers to understanding, but the only people here in this discussion are the ones who haven't already become discouraged. It's no wonder when things are seen as not-a-problem by people who didn't have a problem with them.
People keep repeating this, it sounds terrible.

I'm at the airport 30 min before departure from a small domestic airport, 1h before departure for a domestic flight from a large airport, and maybe 1.5h, max, before departure for an international flight. For none of them do I expect more than 5 minutes of security.

Unless I'm flying to the US in which case the security charade takes hours.

This is a TSA problem not a general problem with air travel.
This is SUPER back of the napkin-y, so I hope I haven't done some crazy wrong math somewhere or used inaccurate stats, but I was trying to get a sense of context for how journals fit into overall university funding (which in Finland is almost all public funding).

All numbers are for 2011

Finland GDP: $273.7B USD (1)

public expenditure on education: 6.8% (2)

calculated expenditure on education: $18.6B USD

total cost for academic journals: $21.5M USD ($19M EUR) (3)

journal cost as % of yearly university funding: 0.12%

enrolled university students: 168,983 (4)

yearly cost per student for academic journals: $112 USD

"4. The system achieves a level of trust that meets the users’ expectations of affordability, privacy, safety"

This is Google. I assume they anticipate low expectations.
It depends on how you define your terms. If you think of the RESTful API and the Authentication mechanism as two separate systems, you can have your cake and eat it too.

We use stateful JWT to "fail fast". That is, we can quickly reject invalid authentication, but we still look up the hash in the database before we actually use it. Our systems that do API and Auth are separate enough that the stateful/stateless distinction isn't useful.
Does Adobe still?
> aversion to tinkering

That is my biggest (and really only) complaint against Apple. Sometimes you have to go under the hood and do a few things. I don't know what Apple has against this way of thinking though.
Files exist because persistent storage is slow, copying data from RAM to disk is slow and we'd like to have a way to refer by name to blobs of bytes, but in the end it is only there because it's a useful metaphor. If the metaphor gets in the way of our ability to use the storage medium you can either do a mapping (like the direct memory mapping you refer to), which in this case would almost be like a backwards compatibility layer, a more involved scheme where all RAM is backed by persistent storage and devices only keep a flag which objects are currently being worked on and which are stable (an 'open' file would simply be marked as currently in use by an application but there would be no explicit save, just an unlock), or a completely new system based on an image like architecture (see: smalltalk, some lisp implementations). There are some drawbacks to that model (such as harder collaborative development) but I see no reason that applications could not be packaged that way even if the development used a more traditional method.

It would be fairly trivial to layer a conventional filesystem on top of such a persistent object store to get the best of both worlds, which would - amongst others - give you instantaneous suspend and re-awaken and other goodies.

If true this will vastly change the way we use computers.
Yep. It would have to require a regulating body like the IRS to be involved, since new hires are reported against EIN.
People seem to really wiggle around what constitutes state, when it comes to auth/autz and REST.

Some people seem happy with a tiny amount of state to manage user sessions, which makes REST harder.

Other people use tokens of one flavor or another, which may have more security vulnerabilities than conventional sessions, although I'm not convinced.

Shared secret HMAC style is another alternative, although I'm not clear how to make that work with javascript clients in browsers.

Some people just throw the whole authentication question into headers and do basic auth.
Yes but doing that takes some time, and then correcting the numerous errors takes more time. So it's not necessarily more cost effective than using template data entry forms. Some doctors now dictate, and then rely on transcription services which use speech recognition to generate a rough draft followed by human transcriptionists to fix most of the errors.
yes, that's the method everyone has been waiting for:

- (void)resolveDropOffLocationForRequestRide:(INRequestRideIntent *)requestRideIntent
So, if I'm reading the advice right, then ...

* Using JWT for authorization, particularly for one-time use == GOOD
* Using JWT to represent long-lived persistent session state == BAD

and, always transmit your tokens in all directions over HTTPS.

This seems like useful advice given all the reasons put forward. Do I understand correctly or did I miss anything?
It doesn't have to be this complicated. It only seems complicated because your solutions are stuck in the context of memory mapping.

A very simple solution is to add another logic layer to GPU processing, like a shader. It could be the "asset shader," it would run on each frame and tells the GPU what assets to start preloading, etc. That would give the programmer tight control over asset loading latencies without having to load everything at once.
Cisco WebEx and Jabber own corporate voice communication (mostly because everyone uses Cisco VoIP phones). Skype is used mostly in the SMB market.
Oh neat, I had no idea that existed. Thanks!
I think that category fits pretty well!
But that conflicts with the "Optimize revenue" directive.
Oh — probably something like that, yeah. I have uBlock installed in Safari.

Nice fallback (to just “my city”). It gets the intent across just fine, third-party failure (or client-side blocking) be damned :)
Right, elsewhere in these comments it was pointed out that they are talking about a 1,000x improvement in latency vs flash memory. If they are using PCIe x4 and x2, then it seems that their throughput isn't going to be much better than existing SSDs.

Improved 4k random read and write would of course sill be a big win.
I remember hearing the boom from the STS117 space shuttle in San Diego when it was landing at Edwards back in the summer of the 2007. Shit's loud, even at 100 miles.
How do TechCrunch articles get on the HN homepage so often? They're all horribly written and full of errors.

Cockpit visits are still allowed on the ground, it's only in flight that it's no longer possible.
Those things are just the neurotransmitters spewed by people who are becoming analogues to neurons. (Not aware of why they are filtering and passing on signals, but somehow performing some kind of decision making in aggregate.)
Could be for performance reasons rather than a technical blocker. That said AES-NI instructions do make encryption pretty fast so it's anyone's guess at this stage.
The article does mention that the size of the aircraft affects the size of the boom.
History and Background of JavaScript Module Loaders
Screenpresso+Pro+1.6.4.0+Serial+keys+Free
I got a Macbook Pro as work machine in late 2014, having used a Thinkpad before.

1. Mac OS is just too unfamiliar. It starts with the keyboard layout, which I reverted to Windows-style after I went crazy trying to find the square brackets. (Which, probably for aesthetics, they didn't bother to print ont he keyboard.)

2. Mac OS's poor multi-monitor support regularly drives me crazy. To their credit, they have ironed out a lot of the bugs in Mavericks, but there is still plenty of stupid behavior (e.g. screen 1 sliding back to the desktop from a fullscreen app when a new window opens on screen 2, or a messagebox from an app on screen 3 opening on screen 1, completely out of my sight). Windows is somehow much better in this regard (at least, I was not annoyed by it that often), and even Linux has very solid multi-monitor support these days (at least for me, YMMV).

3. The userland is UNIX, but does not match my expectations well enough. It's basically in the creepy valley. For example, I was using units(1) one day and wondering why it gave a syntax error when I tried to use a power operator (like "2^64"). Then I noticed that I was in the Mac terminal, not in my Linux VM (where I usually work), and upon inspecting the manpage, I found that they hadn't updated their units(1) since 1991 (wtf).

4. The company where I work is mostly a Windows shop, so corporate IT is based on Microsoft products (AD, Exchange, Lync aka Skype for Business) all the way through. While there are Office for Mac, Outlook for Mac, and Lync for Mac, these are still no match to their Windows counterparts in terms of polish and OS-level integration.

All in all, I'm already set on going back to a Windows notebook when it is time to get a new machine. (It's not like my Linux VM cares which host OS it runs on, anyway.)
It is even a bigger nightmare if you have chromecast streaming to a TV. Now you have another volume control (which chromecast usually takes priority in this situation). This have been the biggest usability issues I've had with Android.
Depends on your needs.

Probably just the idea of being a replacement for Square and similar readers.

But it'd only be Apple devices that can pay at that point, so not really worth it.
I've been using macs for I guess a decade or so now and I still have no idea what the option key is for. When a keyboard shortcut is like ^+⌥+F6 I just mash buttons until it works. Why do they use a different symbol on the button than in the UI? I really have no desire to learn the seven different buttons in Mac OS and I wish application authors would stop using them so they could someday simplify the keyboard.

I don't understand why we tolerative having shift, fn, control, alt, option, and command, not to mention ⌘ whatever that is. Is it really necessary? Do I need to be an Apple historian to be able to understand the primary input device on a Mac?

Command makes sense. And we need shift for capital letters. Let's just leave it at that.
Maybe I am just dumb but I cannot really understand the "Address is pretty separate from directions in both the old and new system".
You usually know where you live (i.e. how to get there) so the only reason you need to have some kind of coordinate system (be it "conventional" or the one we are discussing) is to tell someone other, including the postman, how to get to you.

I.e. - I really do not understand why "Hi Ibrahim, I live at Alpha-Unicorn-Honey, just drop here when you are in the area" would beat "The train stops at Nadira, from there you walk 2 miles in the direction of the sunset, when you reach a rock looking like a kneeling woman you turn in the direction of the face and walk anoter mile - and there is my hut".

So far the only place where I believe this system would help is in large Japanese cities (Tokyo) etc. because they don't have "named" streets, most of the time, and at the same time most people can be expected to have access to technology.

(Maybe it's the same in China, but never been there so I don't know how it is)

I sincerely doubt that people living on the outskirts of the Gobi desert will routinely exchange their three-words coordinates over whatsapp and then get Google Maps or whatever to guide them to the desired destination.
That's it in a nutshell. A lot of developers also misuse JWT in strange ways, and the meat of this article was responding to those weird/unsafe use-cases.
Heck, if someone's going whole-hog on file integrity, I'd really like them to support the creation of files that are stored "expanded" by a fountain-code.

Rather than having to RAID-mirror every block on my disk, I'd like to be able to pick just some files and say "please store those ones slightly more redundantly, such that they're protected from bit-level disk errors—they're important."
I love the idea of a decentralized internet. I mean we already have cryptocurrencies that are decentralized, why not have that as well?
> Why do you need a DAC?

I'm curious, why do you say that the open/read/write model can't work? I suppose that current software should be optimized to take advantage of better performance, but I don't see why it is obsolete.
> It's a strange sort of progress that wants to brainwash everyone to think/feel/believe as you do. This must be the "diversity" you're always harping about.

"Progress" doesn't mean accepting all beliefs. There is right and wrong, good and evil. "Progress" means figuring out which are the right and good values and inculcating them in the people.
>I admit it, I don't get the draw of these things.

On the other hand these aren't features Apple is pioneering. Stickers, larger emojis and other text effects have been in WeChat/Line/FB Messenger/Snapchat for a while now.

Now that iMessage has them, Apple just decided to give those features the classic Apple marketing fanfare.

So in short, "the children" have been using these features for a while now, Apple just decided to let you know they exist.

OSX used to be ahead of the curve though compared to Windows, now...it's falling behind. I think that's where people's frustrations come from.
I can feel you. (Even though I am already on Linux.) It's always weird to be sitting there at 26, wondering about how "kids these days" use the internet.
Control over hardware doesn't really buy you anything here. Just about any hardware can use any filesystem with, in the worst case, the requirement that you have a small boot partition using the legacy filesystem.
Thanks a lot, no I never noticed the search bar.

Thanks the website has been taken down.
Profiling has a lot of its own pitfalls. Use a sampling profiler and your calls to StringBuilder might get compiled so that there are no safepoints inside them and you never see them[0]. Use instrumentation, and you can massively over weight short methods because of the overhead.

[0] I would think this can realistically happen for StringBuilder calls, but I'm not 100% sure.
JWT is often used as an implementation of signed cookies.

Also, don't use signed cookies unless you have a crypto expert on staff.
Like you said the SM is an approximation, so even with 26 free parameters there is a lot of physics that is left unexplained. In my experience it seems like far more than 26 free parameters which go into MC simulations, for instance with something like Madgraph. Perturbative QCD predictions also seem to rely heavily on experimental measurements. I'm not sure things like half-lifes can be predicted accurately from 1st principals either. So I don't think it is correct to say that from 26 parameters and first principals we can predict all experimental results. Even if we could do this in theory, in practice we do not have the computational power to do it, so we rely on approximations which are implicitly guided by experimental results.

I agree that the number of parameters needed is less than the number of experimental measurements though, I confused that.
It is a problem because the actual checks take minutes but all the delays turn those minutes into hours. And probably those hours translate into opportunities to bypass the various checks.

Does setting it to mute not work? My iPad 3 makes the noise on plug and unplug exactly when it is not muted.
ZFS needs very little memory to run. Performance is definitely better with more RAM, but the overwhelming use of memory in ZFS is for cache. Eviction is not particularly efficient due to the cache being allocated from the SLAB allocator, but that is changing later this year.

Getting ZFS to run on the Apple Watch is definitely possible. I am not sure what acceptably means here. It is an ambiguous term.
