Abstract: Working memory (WM) activity is not as stationary or sustained as previously thought. There are brief bursts of gamma (~50–120 Hz) and beta (~20–35 Hz) oscillations, the former linked to stimulus information in spiking. We examined these dynamics in relation to readout and control mechanisms of WM. Monkeys held sequences of two objects in WM to match to subsequent sequences. Changes in beta and gamma bursting suggested their distinct roles. In anticipation of having to use an object for the match decision, there was an increase in gamma and spiking information about that object and reduced beta bursting. This readout signal was only seen before relevant test objects, and was related to premotor activity. When the objects were no longer needed, beta increased and gamma decreased together with object spiking information. Deviations from these dynamics predicted behavioral errors. Thus, beta could regulate gamma and the information in WM.
There is a guy in the C++ community known for writing lock-less data structures (Tony Van Eerd), if I recall correctly one of his advices is to think multiple times before ever considering writing such kind of code.
You can't opt out of the monetary system that's been imposed on you by your govt, because your govt's desires are backed by the use of force[0]. Short of moving to a different country, paying off the enforcers, or going into open rebellion, everything else is a fantasy.

So I couldn’t legally advertise alongside marked up collectibles that “the fad is coming back!” Or I just couldn’t legally collaborate with others to do so? I feel like it’s not necessarily a false claim, just a hopeful one.

As a corollary every company in some respect uses spin to become who they are (you gotta fake it til you make it). Half a decade ago Tesla was making outlandish claims about their ambitions and they’ve not stuck to many of their commitments but no one accuses Elon Musk of fraud. He’s hopeful, not fraudulent.

In which cases are native still better than PWA?
Well, the data does not just appear on strava all by itself. I made an assumption that a non-neglible fraction of the data uploaded was from Garmins/fitness trackers or similar devices (like watch for tracking your running etc).

I guess people could also be using their smartphone app, which I am less familiar with. If I'm misunderstanding what the source of the data is I apologize.
This seems like the kind of ranting that we've already asked you not to post, so could you please stop? Generic tangents just don't bring about the kind of discussion we're after here.

> I meant 'software development' as a craft where it would only be myself touching the code, liaising with the customers, and doing all the design, coding, testing etc.

This is my favorite part about working on iOS apps: Most of them are small enough that they can be built and maintained by a motivated individual, and for most of my clients it is natural to outsource some of the decision-making because their in-house folks only understand websites or desktop apps.

I wish this "software blacksmith" development model was more common.

No, they will only stop when there are no more morons left to be milked.
1 hour timeout on runs. I'm assuming that means from one command execution to another, not per batch but shrug. Once it times out it looks like they save state and you can reconnect but I've not checked very closely. Same for saved data but I assume there's some way to chuck it into drive which is the storage backend as far as I can tell.

I guess you could have just read a lot of books. I don't know if libraries are being closed down in the US, but that's happening a lot now in the UK for cost saving reasons/due to lack of demand.

With a computer & internet access, it's easier to stay isolated. Though I guess TV and radio, even newspapers and writing for pen pals also provides the same substitute sort of-interaction without actually having to interact.

For all the negatives (assuming we say 'all these people should just go out and socialize' - unfairly), I think online communities make a huge difference to those who are physically disabled, need to stay home to care for someone all the time, or are stuck in the arse end of nowhere.

There's still a certain sense of egalitarianism in internet forums. One commenter's opinion is (by default) worth the same as another's.

That said, in most open comment sections in modern times the actual 'community' part is underdeveloped. Everyone is so loud, there's always someone positively thrilled to play devil's advocate with maximal cynicism, always someone there to interpret a comment unfairly, precious little sympathy for the views of others.

Actually every e-mail client I've used has had its issues, including commercial ones. TB isn't great for composing fancy formatted e-mails; I haven't figured out how to bottom-post such e-mails at all.

Outlook seems to change lots of little things I don't care about every release, making it harder to use, since I can't gain familiarity well. Furthermore I hate corresponding with people who use it, since it puts a lot of effort into breaking threading.

Thunderbird is just not a reliable store of data; perhaps it's fine for people who IMAP and store data on the server, but it's not for me.

Which leads me into trojita; this is actually a fairly nice imap client, but I tend to keep my e-mail local, so I haven't used it much as my daily driver.

mutt is terminal-only which rules it out for a lot of people (note that terminal only doesn't rule out reading html e-mail, it just rules out reading html e-mail in a manner that looks any better than lynx/links2).

All of the notmuch frontends I've tried are kind of "the 10% of gmail that's easy to implement" and then abandoned. Bower has been both the most performant and the most stable, but it, like mutt, is terminal only, and is relatively feature-poor. I'd hack on it, but it's written in a statically-typed dialect of prolog that will probably take me weeks to learn.

Note that I actually use a modified form of notmuch-web for handling mailing-lists; threads come in tagged as unanswered, so people can easily see what needs to be responded to.
While true, I tend to believe regulation then empowers this same kind of thing to happen, but legally and unreported at firms like JPMorgan, Goldman, Morgan-Stanley.
Let’s say you have to leave the country with all your saving. I’d much more comfortable carrying it in btc than cash.
That would still be investing, business would pay taxes on the Bitcoin value at the time of purchase as revenue, regardless of conversion to fiat in whole or part.

I don't think that's the right response, especially not now. Tell soldiers not to bring online fitness trackers, and then punish the ones who forget.
Cryptocurrencies have proved popular for drug dealing, extortion and speculation/gambling. They will probably also help with tax evasion and money laundering. Those are applications of a sort if not very positive ones. The decentralization is necessary to put the above outside government control.
At least half of American foreign policy is always geared towards scoring politics points internally. A lot of the actions have nothing to do with the actual situation in a foreign country but with the situation at home. Korea is a good example and the whole middle East situation another one.
Chaos Monkey and Kyle Kingsbury's work on the Jensen tests inspired us to make this (https://github.com/gundb/panic-server), which lets us simulate all sorts of failure cases. It should be extremely useful to others if they enjoy stuff like Chaos Monkey, etc.!

I’m curious how Apple will balance PWA support with the business case for the App Store.
I sort-of agree that the code in the article is not really future-expansion-proof, and in fact, it's not really incompetent-programmer-proof. In the enterprise, you'd probably write incompetent-programmer-proof code, even if you're very competent yourself, just to prevent trouble later.

Kernighan and Ritchie did not need to bother with less profient programmers maintaining their code. They wrote what they and their friends understood, and apparently that was this.

So in short, the GP (bsder) does have a point.
Don't forget Henry Ford.
Kinda like the banking system?
I'm not going to correct all the replies to this post, I'm just going to suggest that you should read TFA. This is about the songwriter's cut, and if you didn't write the song you performed, this changes nothing about the 0% of the songwriting royalties to which you were entitled.
So unless I’m mistaken, PWAs in their most “ideal” form (vs how Apple has implemented them) kinda hang around after I’ve visited them, can use some arbitrary amount of disk space, leave background processes running, and can send push notifications even after I’ve navigated elsewhere. It sounds like to some extent they effectively get to install themselves on my device without my permission, with visiting the site in question acting as consent. Am I incorrect?

If all the above is true, I can’t say I’m too happy with the feature as a user and hope there’s a universal off switch buried in settings somewhere. If I choose to use a website over a native app it’s due to its ephemerality, so I have no interest in web apps that stay past their welcome.

If on the other hand the behavior is 100% opt in, that’s fine as long as I’m not shown banners trying to sell me on the PWA all the time.
That's true. Nevertheless, it's interesting (though unsurprising), to see the areas where Strava users don't run.
> Ivy seems to have "solved" this problem by having almost no themes. This is not exactly the solution I was thinking of...

Yes, it really is a chicken-egg problem where I think you need to start with at least a half-dozen attractive themes to get attention.

Theme designers are not going to build themes for a site generator that nobody uses. And nobody (relatively) is going to use a site generator that has only a "document" theme.

Generators like Hugo, for whatever their faults, have dozens of really nice-looking themes so it's easy to find something close to what you want and either use it as-is or make some minor tweaks.
PWAs work without connection, or with a very lousy or limited data connection, without having to download a lot of stuff the moment you need it the most. In other words, the vast majority of advantages of native apps.
Universal Basic Income in the form of cryptocyrrency
In cases similar to desktops with electron vs. native (although with different requirements) where either you need access to significant native features that are not supported in the browser, or if your app is process intensive, i.e. graphics heavy games.
But if people are paying you for something, you're generally solving a problem for them, right?

Or why don't you convert your crypto to fiat and do Airbnb?

I am just challenging that enough people consider fiat currency such a pain in the ass that they will leave Airbnb and flock to Cryptocribs (even considering they would have the quality, quantity, and trust of Airbnb someday). An "average" person sees the BTC price of 0.0009 per night and doesn't even know what value that in their base currency. Of course, if it becomes normal to pay with BTC than it would work.

Where? I went to check and didn't really find any (I checked only the Norway-Russia border, that's shorter than the other ones :-) ).
Indeed, they are. The same should be said against those who look down upon Caucasian Europeans because people from Europe bought slaves from Arab traders and took them to the Americas, about British ex-prisoners who took land from the Aboriginals, about Europeans who took land from native American tribes, about... well, you get the gist. What happened in historical times is just that, history. The inhabitants of modern Turkey carry no guilt for the atrocities of the Ottoman empire, just like modern-day Japanese (except for surviving war criminals) are not to blame for the misdeeds of the Japanese empire, nor are current Europeans the same as those who traded in slaves or established colonies in Africa. It is good to have this sorted out so people can get on building functional societies based on the here and now, not on old feuds and historical misdeeds.
I think overall the connectedness is actually a bad thing, because it didn't come with education in critical thought and temperment. We're losing the battle of enlightenment to echo chambers of hatred and fear.
No, this isn't clever at all. Its an optimization for when you need to write a lot of little utilities that need to parse arguments. It probably came out of a day of writing tools, and after the fifth time of rewriting that while/for loop someone got pissed and made that macro. I use this macro all the time on both 9front and unix because it makes parsing arguments trivial (and I don't use long options, but that's more because I'm a plan 9/unix extremist than for any technical reasons).
I would say the best thing about the internet is that it's not just one thing. It's multifaceted. It's a lot of things to a lot of people.

For instance, I personally don't do any social networking at all. But I immensely benefit from sites like wikipedia, or by other contents that I would have otherwise never read about.

So, I don't think you can say there's one thing that is the best about the internet. It's so many things. And that's great.
Idea:

Rather than all-you-can-stream, charge a low rate per song play to users. Assume that existing services charges $15/mo, and heavy users might play 16 hours a day, and act song length is 3 minutes, that comes out to about $0.0015 per play to be the same value proposition. But guessing average is much lower so we could up the rate 2x or 4x and customers come out the same. Everyone gets the same cut of revenue per song play, so popular artists get the same cut of streams as indie artists.

Am I missing something?
I'm saying it doesn't really seem to be a Strava problem, and that the problem on the military side likely already has a solution in place.

Hi HN,

I made a cryptocurrency price tracker, alerts, and portfolio management app.

I learnt a lot in the last 2-3 months of building this app. I thought of sharing my story and my learnings in this post.

If you'd like to download the app, it's here https://apple.co/2DUzTqa

I'd love to get some feedback :)
I can think of one use for blockchains that can't easily be replicated otherwise (at least not with the same amount of security), it's proving that you knew something at some point in time. Putting something in the blockchain is like taking a picture of it with today's newspaper next to it so to speak, except you can't photoshop it.

If I made a groundbreaking discovery today, putting a sha-256 of it into the blockchain would be a very good proof later on that I actually owned it at this time.

But beyond that I agree with you. My (non-technical) girlfriend is looking into cryptocurrencies lately and she watches tons of youtube videos about it while doing her research (TEDx talks and the like). Easily 90% of the claims of "blockchain is going to revolutionize X" are easily dismissed either because the blockchain can't do what the person claims or there's an other, often simpler solution to this same issue. "Use the blockchain for food traceability", "use the blockchain to validate critical equipment firmware" etc... It sounds good as long as you don't think about it for more than 10 seconds.

The problem is that in order to realize that you need to have a rather deep technical knowledge about how the blockchain works, something 99% of people investing in crypto probably lack.
My understanding is that this behaviour is all only if you save the web app to the home screen (from Safari).
Modern slot machines don't use just local rngs, they essentially obtain lottery tickets from a central computer. That's how you get building-wide jackpots.
I use Tampermonkey, can you be more specific?
Are you disagreeing with what, exactly?
Totally agreed that preferring one form of service over another is a form of lock-in.

However, in favor of a certain music service:

- with iCloud Music Library, you can play all of your mp3 files on any device, Spotify-style;

- if you purchase an album from iTunes, you own it forever; this is not true of Spotify-streamable music. I've had some of my favorite albums disappear from Spotify, for example.

Long-term, iTunes, Apple Music, and iCloud Music Library seem like a better solution because they allow you to retain actual ownership/control of your own music collection, which helps a lot.
You don't need to hold physical cash to hold USD. You could have a bank account in London, Geneva, Paris, or New York with your pounds, franks, euros, or dollars. If you need to leave the country, your savings are already outside of it. Just like your bitcoins.

The answer seems to be that repressive countries haven't yet put in place effective mechanisms to be repressive with respect to bitcoins. But there's zero reason intrinsic to bitcoin to expect that to continue. On the contrary, since everything is digital the choke points are easier to control, not harder.

You can tag direct account payments with notes. So paying a bill or a school, you attach a note such as “payment for Pierres school trip” or “regarding invoice #1234”. Works pretty damn good here in Denmark.
Better the devil you know. FDIC and SIPC instill a lot more confidence in me (and every single rational investor) than uh Bitfinex or Kraken.
Thing about these telegram pump and dump groups is they are usually NOT lying to anyone. It's all very transparent (if you're inside the group) pump the price when we tell you to, and do what you want once the price has gone up (and it does go up).
It's a trade-off, I think. I doubt there's much actionable intel for an enemy to be found in logistics orders of a base in Germany.
How does this translate over to things like fashion/social trends in general?

Something like "Corsets are coming back for spring 2018! Get on top of the trend at XYZ Fash Inc.!" hardly seems like fraud, but by that definition it would be.

Study: Interacting Gears Synchronize Propulsive Leg Movements in a Jumping Insect

Abstract: Gears are found rarely in animals and have never been reported to intermesh and rotate functionally like mechanical gears. We now demonstrate functional gears in the ballistic jumping movements of the flightless planthopper insect Issus. The nymphs, but not adults, have a row of cuticular gear (cog) teeth around the curved medial surfaces of their two hindleg trochantera. The gear teeth on one trochanter engaged with and sequentially moved past those on the other trochanter during the preparatory cocking and the propulsive phases of jumping. Close registration between the gears ensured that both hindlegs moved at the same angular velocities to propel the body without yaw rotation. At the final molt to adulthood, this synchronization mechanism is jettisoned.

It was not conditional. These were in response to support of UN security counsel sanctions following the ICBM launched over Japan.
Cash money also has the mark of this beast, and the number of those fringe wackos is small.
Just like a native app, the process requires user approval ("add to homescreen" vs "install"). A large difference, however, is that native apps go through Apple's approval process.
If you start and stop your run going different directions it's not too hard to figure out the central point between them, but if you start/stop from the same direction then it's not clear what the "middle" of the circle would be because the radius of the circle is configurable and unknown to viewers.

The US isn't exactly a leader in banking technology. While I agree that cash is here to stay for the time being, the introduction of contactless payments in the UK has made the conversation around dropping cash seem realistic (with he lower fees almost everywhere now accepts contactless, and unlike chip and pin, transaction times are faster than using cash...)
If you really want that, just do a relaxed read into a local variable, increment there and relaxed store afterwards. At least clang will give you exactly the assembly you want, minus the technically undefined behavior:
