It's not a tragedy of the commons. Whether we grow the blocks or keep them the same, the network continues to function just fine. It's a matter of values and how to grow the network. If the miners do nothing, Lightning Network and off-chain networks will route most transactions outside of the blocks. Some in the network want Bitcoin only to be used for settlement, instead of for every payment. We've actually had larger blocks in the past (32 MiB I believe) and it was reduced to combat spam.

The fun poking is mostly about things like 192kHz sample rates and thousand dollar power cables. It's uncontroversial that people can hear mp3 artifacts.
He missed the word special. You need to buy special hardware from Apple to use OSX (or figure out how to make Hackintosh work), while Linux can run on just about anything. Also, sidenote, some places do give out hardware with open source operating systems, eg Free Geek[1], but of course this sort of thing isn't available everywhere.

And what exactly is preventing me from injecting my custom libGL.so that hooks onto the `glDraw…` calls, and downloads the current contents of the bound textures using `glGetTexImage`?

Also OpenGL debugging tools do exist and they work by hooking OpenGL and using the OpenGL accessor functions to show you the contents of every OpenGL object.
Same here. Missed the Coldplay one because I couldn't find artifacts in that "solid wall of sound" style production. The rest were pretty obvious. This with middle-of-the-line Sennheisers, a cheap headphone amp, and whatever sound chip is in my laptop.

> So my suggestion is: remove ALL the modification features from the free version, release it as a separate app called "GitUp Viewer" or something, and then sell the version that is actually a git client.

Hmmm... but wouldn't that be exactly the same problem of "slapping users in the face", except now with 2 apps?

There aren't that many options to distribute desktop software:

1) freeware

2) free to use but ads or equivalent

3) paid upfront

4) paid with trial

5) paid with in-app purchase for some features

6) a free basic app and a pro app

#1 and #2 are not an option here and #6 is too much overhead and complicates the user proposition.

I don't see how #3 is not worse than #4 and #5. Not an option either anyway: I truly think people should be able to try before they buy for such a product.

#5 is all the trend on mobile and has been demonstrated to work (I've also done that on a couple desktop software and it seems OK). IMO it's the best of both worlds if done right: you get a free useful product as-is, but pay to get even more value of it.

If you think #5 is a "slap in the face of new users", wouldn't #4 also be that? :)
That was depressing. The article details the adjustments Toyota made to the food kitchen's system:

> The kitchen, which can seat 50 people, typically opened for dinner at 4 p.m., and when all the chairs were filled, a line would form outside. Mr. Foriest would wait for enough space to open up to allow 10 people in. The average wait time could be up to an hour and a half.

> [Toyota] eliminated the 10-at-a-time system, allowing diners to flow in one by one as soon as a chair was free.

Talk about low-hanging fruit. This is quite literally a case of cutting waiting times by saying "hey, why don't we just stop telling people they have to wait?"

I am wondering the same thing. Interestingly enough, Martin Fowler wrote the article.
The "National Do Not Call List" can be useful in Canada.

Paypal may only contact you if you've requested info in the past 6 months or used their service in the past 18 months.

If they call, you can demand that you be put onto their internal Do Not Call list. They must honour that and you can make a complaint if they do not.

GFS/Colossues are distributed file systems, which GCS doesn't really address (I think GCS is akin to AWS' S3?)
We experienced similar to this at our company. When my coworker and I first arrived, the prior engineers had built the system as a set of microservices but it was completely overarchitected. Our first act was to pull all the parts together into one application.

Now that it's grown, we're starting to look at the microservice approach again, but it's been almost four years since we pulled everything together so it makes much more sense given the load/functionality we have now relative to then.

While I can tell the difference (6/6 in this test), in practice, it doesn't actually matter to me personally. I'm usually listening to music while there are a cacophony of other noises going on (talking/cooking/driving), so the slight difference in the way cymbals are rendered or the loss of nuance in a large bass hit are far from the primary degradations to my listening experience...

The digital audio system here in the UK is terrible. They divide up the available bandwidth so much to cram in more channels the stations sound worse than FM (and they use MPEG2 audio too, which makes it worse). Last week, they crammed in a special Eurovision channel and reduced several other channels from 128kbps to 112kbps to cope. 1xtra (the station I listen to) suddenly sounded so "dull" and slushy.. even just with a 16kbps drop! I had no idea what was going on so asked on DigitalSpy and learnt the above.

Long story short, my takeaway is that perhaps it's not just about absolute levels of quality, but also what effect minor effects in bitrate can have on the underlying codec.
> You may have issues sending money outside of the US

So basically the only reason why people use PayPal is because of international transfers, and as an option to that you propose something which only works in one country.

Sounds great.
do politicians and some charities get a free pass when it comes to ignoring it like they do in the US?
Also not trying to debate one way or the other, but I'd be interested to see those statistics extrapolated over multiple years so we could see what it looks like when you scale for population size. You obviously can't scale when some of the countries are zero (unless, like iceland, they just never have police related deaths).

When population is accounted for with the german total, the US has only about 4x the population of germany, but about 57 times as many police shootings.

That is, from my point of view, exactly the right frame of mind in which to read about it; and it is very likely that, if you have a good textbook (which is by no means guaranteed!), you can ignore its talk of prerequisites, ignore its examples when they require prerequisites that you don't understand, and proceed by trying to understand what its definitions mean in the context in which you are interested.

(Of course, none of that is to knock the usefulness of targeted resources like this; obviously it can be helpful if you can use the whole of a book, rather than tossing out and re-creating parts of it on your own.)

The 128kbps MP3s are easy to distinguish - they sound like audio in a washing machine, going round and round. Listen to cymbals that instead of going CRASH go CBBRASPHHHHHH with the ending being the giveaway. Snares are also affected as they won't have such high frequency peaks so lose their SNAP sound.

Bass drums are also easy to pick out - if there isn't much bottom end then you know it has been compressed.

The a cappella version sounds like she's got a throaty cold on the MP3s. The SSSSSes sound different on MP3s too - it ssssoundsss like they've got a lissssppppp with MP3s.

You may find it easier to listen quietly because then your ears only pick up the highlights instead of getting fatigued with too much volume (where they will shut down after a while).

One person, 5 out of 6, could also be attributed to chance.

The random average for a large number of people and 2 options would be getting 3 out of 6 (like a coin toss). But in the samples would be several 4, 5 and even 6 out of 6 too. In this case it's like 15/18, while is very good but still possible.
This is awesome. I am pretty familiar with Asterisk and can think of a couple ways to do this, but I would love to see a blog post or something detailing how you accomplished this.
The slowness appears to be caused by continual directory scanning. For me at least, turning off the "Refresh when files change" option, and so having to do "view, refresh" or Command-R, made SourceTree be zippy again.

And as I'm usually on a laptop, having less continued CPU usage is a good tradeoff against having to press refresh when I'm going to do something in SourceTree.

For the discussion: I recently paid for the Synergy software KVM even though it is GPL. Synergy's purchase process is very smooth. Paying $10 for the installers was much easier than compiling it myself. And, I was already had confidence that Synergy was useful, good quality, well-maintained software. So, I was happy to support it as long as doing so was convenient.
God, I hate the hydraulic analogy. It almost made me flunk a 101 electronics class because I couldn't connect the dots between the analogy and the physics of what's actually going on.

Similarly, I got 3 wavs and 3 320s. I could distinguish the 128s but not between the other two. Please note that I did this wearing studio headphones (shure srh840).

If Paypal can be sure that fewer of the accounts pumping money through the system are doing so for anonymous multi-identity money-laundering, then the horrifying "we froze your account because started getting Real Money through it and that's suspicious" step can happen less often.

Though, thinking about it, even just switching to mandatory phone-based 2FA (with options to either call or text) would technically require a "we can robocall you" clause. The 2FA system is a robot!

Working with a remote team on a SaaS application != outsourcing enterprise-level work to overseas employees.

With a small remote team you have the luxury of carefully choosing remote candidates and interviewing them individually. Enterprise-level work (read, bringing on teams of 10-50 developers in a short time frame) does not afford you that opportunity.

I'm not sure how large your company is, but it's pretty apparent you haven't worked with outsourced employees on an enterprise-level (7-8 figure) project before.

Surely it's not actually acceleration that you feel most of the time. A constant acceleration is, after all, indistinguishable from constant gravity, and so small acceleration vectors which, when added together with the local gravity vector, are still just a little more or less than 1 g, aren't really detectable - they just feel like gravity is pointing in a different direction. Obviously larger accelerations are detectable as being 'not quite like normal gravity'. When it takes different-to-normal effort to move your limbs, your body gives you feedback about it.

What you can feel is change in acceleration - a sudden change in the direction your body perceives as 'down'. Braking in a car doesn't feel much different to driving down a hill, but when the car's speed reaches zero and suddenly stops decelerating, the jerk as gravity snaps back to vertical is definitely noticeable. It's the jerk, not the acceleration, that throws you off your feet when you're standing on the subway and it pulls into or out of a station.
> So it would be useful to have category textbooks for CS folks which spent less time on topology, and more time on familiar categories.

Agreed, and I should have been clearer in my post above that I was just airing some thoughts on category theory rather than meaning to imply anything negative about the importance and usefulness of X-flavoured viewpoints on category theory for various values of X (including "computer science"). With that said, don't knock topology! See Baez and Stay's 'Rosetta stone' article http://arxiv.org/abs/0903.0340 for a plethora of connections between such seemingly abstruse concepts as topology, and computer science.

Nope. Gaseous FPs are continuously removed and stored somewhere. Of course they require cooling while being stored. Any mishap releasing even a tiny fraction of them would of course be harmless, but in the present culture would result in a global panic.

Other FPs in the salt are circulated out of the core and through a heat exchanger. Some ongoing actinide fission there too. Tiny defects in heat exchangers handling plain water currently cause reactors worth billions to be abandoned (e.g. SONGS).

Some FPs will plate out and you'll need to replace plumbing periodically. That has to be done by robots because the pipes will be ultra-hot and deadly within minutes to anyone nearby.

For what benefit? You improve the fuel cycle by a factor of 50. But the fuel cycle is < 10% of the costs and material flows of nuclear plant. So yes, online FP separation is something a mature fission-based civilization would have. But it is not clear how it helps us, other than to provide a focal point for a new culture to form (which may be a substantial if illegitimate benefit, admittedly).
One of the best use cases of twitter for me is customer service, a few complaints about @comcast is way more effective than calling and waiting on the phone for 20 minutes and fighting with the customer service agent...

192kHz sample rate are unnecessary. In truth, 96kHz is common for live too (as it is half the latency of a 48kHz system).

48kHz and 24bits is what most audio is recorded at nowadays, then downsampled with aliasing for CD quality audio.

I can hear the difference between mp3(320) and flac/alac easily on my stereo both in the car and in my room. The funny part is that you can easily recognize mp3 compression based on high it trims the high frequencies and the high hats are affected by it quite a bit. You can try different lossy formats but i guess it is just damage control. The only reason I use alac and not flac is because iPods only work with alac (and it is limited to 16bit, 44100Hz) and my car only supports iPods :(

Find myself reminded of the late micro era when people came up with all manner of crazy tricks to produce 3D effects and such on the C64 and like.

It may well be that PC gaming producers have gotten "lazy", as they are working with a ever improving platform. Thus they can target "future" hardware rather than attempt to optimize and push what they already have.

This because we see something similar to the micro era in gaming consoles. There games towards the end of a platform generation are more refined and elaborate than those released at platform launch, because the producers have gotten to know the ins and outs of the hardware.
Fantastic, very much reminds me of the style in The Art of Electronics(another great reference).

> can you please give an example of a 'granular' technical decision?

Whether or not to upgrade an underlying library for a service. How many nodes to give a cluster, what features to prioritize on that node. You can do this with a monolithic codebase but you move slowwww if upgrading one unit implies upgrading others. With microservices, you could even write every service in an entirely different language.

> It would be more accurate to say that microservices is what you call a system that you made distributed even though you didn't actually have to make it distributed.

You don't have to make anything distributed. I think it's more apt to draw an analogy to the Actor paradigm—microserves are discrete actors in a distributed system and can be analyzed independently from the other actors.

All the microservices movement has really brought to the table is "no, you don't need to distribute your work to benefit from the looser coupling". If you're seeing anything more, I suspect there would be significant disagreement in the movement about it.

Hello HN!

I designed meml.io to make web research simple and more organized. The basic idea is that meml.io tracks your search efforts over time, and stores separate sequences of queries in "streams." This is especially useful when searching iteratively or refining web queries. Streams can also be shared across users, allowing collaborative research.

Right now this is just a side project, but if anyone out there sees potential for something more, email me.
