@jerf refers to "spaced repetition" which is a specific form of the "practice" you mention. Basic practice is of course ubiquitous. Spaced repetition is less common, but becoming better known.

Incidentally:

You mention sports practice. This is a really fascinating topic, possibly different from mental recall such as spelling and theatre lines.

A beginner in a sport can practice in a very general manner, since anything they do is likely to produce improvement. Someone who has just started learning tennis may benefit from the occasional game of squash or badminton, for example. Put another way, in problem space they are very distant from the target, so any effort has a reasonable chance to take them in a direction which is vaguely towards the target.

An expert athlete, however, must practice very specifically. They are very close to the target: only movement directly toward the target is useful. The tolerance is far less, the number of directions they can take is far fewer.

Additionally, the extremely fine control of the musculoskeletal system necessary for athletes degrades slightly with absence from practice. The specific activity must be regularly practiced to achieve peak performance, and ensure the neurological specialisation is maintained. This is why professionals must "warm up", to ensure the nervous system is tuned to peak performance. (Avoiding injury is a separate and complicated issue.)

Spaced repetition is related to this, since athletes must indeed practice/train. But the time element here is very complex, and unique to the sport, the athlete, and much more. Frequency, rest, intensity, endurance and more are in that mix. Add mood, motivation etc and it becomes almost overwhelmingly complex. Possibly why some of the finest athletes aim to take emotions out of the mix: simplicity and reliability. Perhaps!

A lot of this is still poorly understood, as it is with memory and recall.
I have been collecting mystic quotes in the same vein.[1] This one, from Bernadette Roberts, is my favorite:

> There is a silence within, a silence that descends from without; a silence that stills existence and a silence that engulfs the entire universe. There is a silence of the self and its faculties of will, thought, memory, and emotions. There is a silence in which there is nothing, a silence in which there is something; and finally, there is the silence of no-self and the silence of God. If there was any path on which I could chart my contemplative experiences, it would be this ever-expanding and deepening path of silence.

The web-based implementation means you only have one codebase for both Slack in the browser and Slack in Electron. So adding Qt in addition to their browser client means they have two disparate clients instead of one client (plus Electron glue code).
Yeah, I think it's important to stress that.

Building an application is easy. Maintaining it, adding features, scaling it, integrating with other services, building platforms… those activities all take a lot of other work.

I work at a small company whose core product was developed primarily by one or two developers. We now have substantially the same functionality with an engineering team of ~13, but constantly have a huge amount of work we want to do. Things like scaling, refactoring legacy code, paying down technical debt, handling complex and tricky edge cases that could previously be glossed over, and building administration tools – these take up _phenomenal_ amounts of time, especially if you want to work at a sustainable pace. I can totally believe that larger software houses need a surprising number of engineers.
> requires you to believe that Apple and Google both are in cahoots with Facebook to give them a rootkit-like API for mic and location access that override all of the OS-level controls and warnings about when that hardware is in use, and hide it from the data and battery usage stats on the phone.

You mean like when they gave Uber special access to grab screenshots even when the Uber app wasn't running? Yeah, totally impossible to believe.

For experiments like this, use items that have high CPM. Gold, silver, niche personals and preserved food are great canaries.

Try doing different things. I don’t think name brand vendors do pervasive audio surveillance. I do think they broaden the scope of your intents. Use GBoard dictation or similar tools to write. Write stuff down in different contexts. Use apps in different ways.

Amazon and Facebook share in near real time. Anything you do in a consumer Amazon property is feeding context to FB.
I am unsure why Microsoft Teams isn't used more.

Quadratically.

Line-of-sight attenuation of an EM wave in the empty space is quadratical, whilst - for example - attenuation of an electrical signal in a wire is exponential.

Obviously this is a super simplification...
Both fascism and communism are Industrial Age ideologies that had faith in certain aspects of progress (modern efficiency and order, economic modernization, shiny steel war machines, etc.). Certainly fascism and Nazism had a lot of Romantic, anti-modern reactionary ideals, but it was synthesized with a lot of the trappings of progress. The Italian Futurists were compatible with Italian Fascism, after all.

Not sure how the market crash applies to progress, unless the Roaring Twenties were supposed to be an unprecedented time of irrational economic exuberance that foreshadowed our modern credit-driven economy.
Oh yeah, I totally agree. They just do a very good job at marketing their jobs. I mean, no other company has a movie that revolves entirely around how desirable an internship with them is supposed to be [1].

Sure money is real; we can't explain our world without it. Its instantiations/records are physical (and therefore each is 'tangible' in some appropriate sense).

e.g. marks on paper, magnetic domains pointing this way rather than that way, electrons being here rather than there.

When we develop new tech, wealth potentially increases -- so funding tech startups is an appropriate avenue for creating new money.
The New Blacklist
That could happen, but it is likely there will be a significant contraction in VC funding at least initially in the event of a recession.

Firstly, the very low interests rates in the US and worldwide the last decade provide very limited room for governments to reduce cost of capital. Current fed funds rate is 1.42% after being essentially 0% since 2009. In 2007, the rate was 5.25%. In 2000 before the dot com crash, fed funds rate was 6.51% (dropped to nadir of 1% by 2004). [1]

Unless interest rates rise dramatically before the next recession, the US govt will have the least monetary policy ammunition ever to respond to a recession. So there may not be that much reduction in cost of capital.

Perhaps more importantly, any further fiscal tightening in advance of a recession could be very destructive to venture capital. One of the reasons VCs have so much cash now is that investors are chasing yield -- with govt debt at all time low rates (meaning high prices), and negative interest rates for some major governments, and with the stock market in one of its largest bull markets ever, investors have been investing into ever riskier asset classes. the laws of finance state than when interest rates go up, bond prices fall, and stock prices fall as well [2, 3]. yield will become cheaper (ie you can get higher return for lower risk: imagine getting 5% from a government bond today, and an expected return of 8-10% for large cap stocks: no one would invest in super risky VC in hopes of maybe 12-15% returns). with attractive returns available for lower risk, investors will cycle away from investments like VC and towards large cap stocks and bonds

that's the theory, and in reality you observe a contraction in VC after recessions (post 2000s, post financial crisis). then capital leaves the VC space, so deals are less competitive and prices are lower, and the VCs that stick around make lots of money, then other people try to get in on the VC returns, prices go up again, returns go down, and the cycle goes on

This currently seems to be the only successful business model. Give something for free to get traction. Then slowly erode the free part, and try to get as many people as possible to run on the subscription treadmill. In most situations open source, open protocols and open data formats are an anathema to the cash register going ka-ching. When you start spending other peoples money, they are sure to remind you of this simple fact.

I found this pcmag link more enlightening than the NYT article.

https://www.pcmag.com/news/359702/us-broadcom-qualcomm-merge...

Specifically, the last paragraph,

"Broadcomm added that most of its board of directors and senior management team is made up of Americans. It also contends that the company's plan to buy Qualcomm will no longer fall under CFIUS's review when Broadcom finishes relocating to the US."

It seems CFIUS wants solid assurance that this happens so the US can continue scooping up all the communications of everyone world wide.

The US government didn't appoint Qualcomm winner of the LTE market with IP protections just to let them sell it off to a company outside US control.
But it's very difficult to prevent unnecessary dependencies from triggering in all cases. Consider a map (dict) with some values. Some outer code depends on the map. This code builds some DOM elements and sets values based on the values in the map. Now, if the map changes, all the elements will be recreated, even if effectively some irrelevant part of the map changed. Of course you can prevent this from happening by doing smart diffing on the map, but now you've effectively moved the problem from dom-diffing to map-diffing.

We're at the point where not much matters anyway. The phones we have are amazing. Sure, it doesn't make much difference, but it's a selling point.

Other advertised features which don't matter to most users: the notch, AR, full size display, active display on edges, assistant updates, AMOLED, app privilege restrictions, curved displays, ... They're all good for advertisement and gimmicks. They may improve the phone a little bit. They're not needed and almost everybody cares only because they were advertised. (If they care at all)

There is definitely a poison in our profession, I definitely have to fight the urge to make sure no future changes will break something, instead of just budgeting time to fix breaking changes later. Especially since no one seems to remember when we all agree something doesn't need to be bullet proof. Just today there was an expression of disbelief when I reminded people I'd built a tempermental UI for some internal tool. Never mind that it was a conscious decision to prioritize a better UI later if we found the tool useful and found the UI was causing problems.

REST and GraphQL have slightly different use cases. REST is simpler, both in concept and implementation than GraphQL. GraphQL offers more flexibility in exchange for that added complexity. GraphQL puts more of the burden on the front-end/client-side code to define the data they want, which is a good fit for services that have many different consumer platforms that require different data (web, mobile, etc), or when the scope of the data that should be returned is very context-specific (e.g. I only need preview-size images for this view, but I need a large images and more metadata for another, and some other requirements for a third).
Come on, you can't think of ONE commonality between forex markets and crypto markets? Thats just being intentionally obtuse.
There's a predefined window for when a device can be certified for release with a particular Android OS version. I don't know what the current window is, but devices that are shipping now (Q1) likely got certified some time last year in Q3 or Q4, well within the window for N.

It's significantly harder to enforce things like update requirements after a phone ships - for one thing, it's not entirely up to the OEM in many cases, it also depends on getting carriers to certify the upgrade.
Despite being a walled garden, the IRC gateway was Slack's saving grace. It was what made it palatable to many old-school chatters and people who didn't want to add another proprietary client to the giant list of other proprietary chat clients needed to keep in touch with people.
> Our priority is to provide a secure and high-quality experience across all platforms, and so the time has come to close the gateways.

The IRC gateway was the only way I was interacting with Slack. If it's gone, I'll just stop using Slack. That's ok, but is not exactly providing me a "high-quality" experience. (Meanwhile: IRC clients are capable of connecting to servers with TLS and authenticating certificates in the same manner as web browsers. So I'm not sure about the "secure" criticism either.)

Is there an API that will continue to be available going forward that 3rd party software can interact with?
Right - it seems we agree on that and probably when I wrote:

Even if you don't believe in the underlying security, you can attempt to ride those waves using technology provided to you by GDAX or Bittrex or whatever - the entire order book is laid out for you to learn and think about, and speculate on. That's easier to parse than odds for .. a blackjack hand? Even a roulette wheel probability play requires some basic training in probability.

You read that as, the odds are easier to parse for crypto. That's not what I was saying, even if I worded it poorly such that it could be taken like that. It's just not an apples to apples comparison, since with a card game you can construct a mathematical model of probability around it. You can't do that so easily with many other types of speculation and investment (let's suspend argument about THAT distinction for a moment).

But my point all along is that it doesn't matter; investments can be assessed non-mathematically by following non-mathematical sources of data and making predictions. History, politics, law change and it's extremely difficult to ascribe statistics to every possible outcome, at least for almost everyone. Otherwise, there would be no market at all for the vast majority of 'investments' / 'speculations'. Only mathematicians could be involved. Now, there are people that make a living out of creating statistical models around stock movements, but that doesn't mean that every other person alive who doesn't and still pursues purchases of stocks is doing so with more risk than throwing all their chips on Black 26. And it is the same with cryptocurrency.

To circle back to the original point, yes, I feel it's rather hypocritical that casino games are open for business for the little guy, but when the little guy uses a web app with a UI with order book details to try to play the cryptocurrency market, a tool of the type really mainly known primarily on stock trading floors until recently, suddenly the little guy needs the law to step out in front to protect him from himself.

I've seen stories where people could not explain why they were suddenly seeing certain ads in their feeds, and they thought Facebook had recorded some keywords from a conversation.

For example one guy had a buddy who had recently purchased a certain motorcycle, and all of a sudden he started seeing ads for that motorcycle.

But... really there's a simpler explanation than the microphone. Although of course it doesn't by itself rule out the microphone being used.

Facebook can just see when you are in the same location as some other people, and see what things those other people are into, and then signal whatever ad networks that you might also be a prospect for those things. Visit your buddy and see his new bike? Start getting ads for the same bike. No audio needed, just location services and some posts on FB from your buddy about his motorcycle. And there are other sensors beyond that. A lot of things are possible once the user has granted permission for use of various inputs.

Also if it is the microphone as the story suggests it could be in some cases, the evidence for it being any one particular app is thin. There are other apps that get granted microphone access by users all the time, and some of them should be looked at, not just Facebook. Not to defend Facebook here, but the net should be cast wider than just one app, even if the ads are appearing on Facebook, which itself is perfectly capable of gleaning interest information from multiple sources including other ad networks fed by other apps.
> I'm not sure if I agree with their choice

Ha! Keep holding out.

Great tip. Thank you. We'll update the post.
They say in the article they track your location. I think it's more likely the ad happened from that.

Just saw this via another recent HN thread and started reading it. The writing and exposition of topics seems good to me.
Just got back from Kauai a few weeks ago, it was great. Anini Beach was great for snorkeling. The north shore beaches were great in general and relatively uncrowded. Tunnels Beach was rough and not really snorkelable, but you can if you really want to. Poipu was fun, but packed, and the water rough as the sandbar was out. Hit the canyon, lots of old tourists, but still worth it and at the end of the canyon (at the last lookout point) you can hike the Napali coast however far you want.

There isn't much night life in Kauai. Things tend to close down after 6.

AFAIK, you can still hike the trail, just not legally camp overnight. We paid a bunch extra for a Jeep rental and had fun exploring the inland dirt roads -- it was worth every dollar extra.

If you have any questions about recent Kauai/Maui, I can answer.

Once your data is collected, you have no control over it any more. Are you sure there's a valid retention policy, it is actually working and enforced, there are no secret agreements with e.g. the national security apparatus, and it is absolutely secure from malicious employees?

That is the big issue around data collection. Even if you're fine with it being collected now, you might not want a recording of this at a later point. For many different reasons. But a big one being that it's really easy to twist your words against you.
