In my experience, understanding theoretical concepts is challenging because the process of learning is often not legible [0].

What has worked for me is having multiple periods of immersion into a concept or topic, while referring to multiple sources, with notes [1] summarizing small bits as I learn them. I keep refactoring those notes as my understanding grows, to include coherent maps of larger and larger chunks. On short time scales, my learning is not measurable, but experience indicates that my understanding grows over time. Looking back, my periods of immersion range from a few hours/days, while I tend to revisit topics every few weeks/months. I guess this falls under the umbrella of spaced repetition methods.

Since my interests and pursuits are very diverse, and I'm seldom "finished" with something, I don't like the psychological weight of todo lists [2]. I maintain lists of interesting stuff [3], and several hundred browser tabs [4] but they're mostly not things to be checked off, and languish peacefully for long periods. That said, I'm on the lookout for better knowledge/idea management workflows and software. What I currently use is organically grown, and very messy.

That was for theoretical understanding. Practice helps, for things one "does".

I read whatever interests me until it doesn't interest me any more, and I quit reading things that don't interest me. I don't say that to be flip—it's actually what I do, and it has allowed me to consume an enormous amount of material over the years. The only trick to this method is not to confuse difficulty with boredom. There are times when I learn to code, for example, or when I read about obscure financial wizardry or mathematics, where my mind drifts and it feels like boredom. But the reality is just that it's hard. Sometimes when things are hard you do have to change your track until you've developed prerequisite knowledge to come back to it. Just make sure in those instances not to decide the thing was boring because you couldn't handle it on the first go.
United seems to have some operational control since the CEO of United said that they would no longer be dragging people off of flights and in the media that passenger was listed as being on a "United Express" flight.

These subcontractors seems to run with lower operational expenses and yet use Americans as pilots following FAA guidelines. United could have a similar arrangement with lower operational costs for overseas flights.
> When the experts in your field say that saying can be done, they are probably right.

Generally yes, but they may be significantly off on the timeframe. One famous example is that once alpha-beta search was invented (in the late 1950s), Herb Simon predicted that "within ten years a digital computer will be the world's chess champion". That did eventually happen, using techniques not even all that different from alpha-beta search, but it took 40 years rather than 10. Many of the 1980s neural nets claims turned out to be eventually vindicated too, but it took 30 years, which was quiet a bit longer than the optimistic portion of 1980s "connectionists" expected.

That's the type of skepticism I usually have with claims today too. When people say "there will be fully autonomous self-driving cars on the road by 2020", I don't doubt it'll happen, but whether it'll happen in less than 3 years I have more doubts about. You could argue AI researchers have gotten better at accurately predicting the timeframes of advances than they were in the early days of AI, but I'm not sure there is solid evidence of that (would be interesting if someone has studied it).

It is probably about as close to ideal as one can get on Windows. The codecs themselves are of course implementations that have been reasonably optimized and at the end of the day the audio framework in Windows is the limiting reagent for further power efficiency gains.
Does anybody know what tool he is using for live coding on top of the slides, where he edits code and runs a repl inside the same window?

Has anybody got any idea?
NAT will make future sales of IPv4 blocks easier? As you say, MIT doesn't need all those 8 million IP addresses, and eventually will adopt IPv6 anyway. Might as well sell surplus v4 space while it's still valuable.
There are simple open source cores for quite a few IO standards. Some ARM SoCs use Cadence or Synopsys cores.

What could be a good advert for RISC-V would be to design a SoC that used a full featured RV64 main core and simpler RV32I cores as offload engines for each IO device.

Part of the problem is that some of this stuff has a pretty short shelf life. There's a lot of optimization knowledge that was useful at one time but is now flat out wrong.

Oral culture is especially prone to this -- at least a blog post or a physical book has a date on it. You have no idea when the your co-worker's suggested optimization technique was developed.
By that logic, does AWS have huge amount of power? Why does it matter what server the content is hosted on? Aren't almost all websites hosted on a remote server? The only difference is Google gets to choose what shows up on their search, and they always had that control anyway.
You're setting up strawmen here.

Any belief system will have extremists - doesn't mean that belief is bad. Perhaps we can judge belief systems by the proportion of extremists they produce? Postmodernism and Nihilism don't look so bad in this regard, whereas religious cults, hardcore racists, and Leninists have pretty bad track records.

And it's interesting that you call out Marxists, but not fascists, Nazis, and religious zealots. Care to elaborate on that?

e.g.
"So this is how you track your lost deals from each month, and we allow you to use different ways of handling bulk leads and smaller volumes of high value leads. So what sort of number do you think might be falling through the cracks in a typical month?"

[...]

"that definitely sounds like something you'd want the ability to monitor individually. Particularly as earlier you mentioned your typical deal size was at least $10k, so that's over $50k each month that our better lead management system could help you with accurately tracking and following up"

To his credit, he did sort of do that, about a year ago.

"I got wrong that the creative class could magically restore our cities, become a new middle class like my father's, and we were going to live happily forever after," Florida said. "I could not have anticipated among all this urban growth and revival that there was a dark side to the urban creative revolution, a very deep dark side."

By ecologically problematic, do you mean that if many passengers opt to fly with adjacent seats empty it would transitively mean that more flights would be needed to meet the demand? (if that is the case it absolutely makes sense !)
Indeed after ruling out HLL I decided that was the way to go. :-) I guess an HLL is more appropriate when you can't so easily keep track of which items have already been added to each set. For example if you were counting unique visitors per day, you would have a lot of sets (one per day), so you wouldn't want to store n visitor IDs for every day. But when an item can only be in one set at a time (and the sets are finite) incr/decr is possible so you might as well go with it.
No, this is the bad news:

I'm fairly perplexed by your reply. It seems so backwards from the way I experience demos. I never find myself with money laying around, looking for a way to spend it, and time laying around, entertaining demos for the hell of it, when I could be working.

If I'm spending my time watching your demo, it's because we have a problem we need solved, and believe you can solve it. You won't even get in the door without knowing what our problem is, so hopefully you'd be able to speak to solving it -- though of course, having to get back to me on precise technical details is fine.

But I can't fathom purchasing something (signed contract) on the promise that you'll add my feature later, maybe.
capital goes where labour goes, and labour goes where capital goes. it's easy to forget that capital is not simply money but everything else that is not labour - buildings, facilities, machines, computers, etc.

this is not a central planned economy. people organize where they want to organize and it turns out large cities are increasingly where people want to do that. people - the ones who choose neither to move to rural communities nor to bring custom - and not capital, are the systematic destroyer of local communities.

mergers, like large cities, are just another symptom of humanity's unsatisfiable desire for efficiency. competition good, cooperation better.

There is something seriously wrong with Clementine on osx, which is unfortunate. Ui consumes tremendous CPU and is laggy as hell. This is a known, reported issue but has not been fixed. It is a shame also because there isn't a decent lightweight player for Mac even close to foobar. Foobar on Mac works well but audio in wine is a mess.
The downside is that the account will likely never be opened back up if a charge is disputed, and any future accounts could also be linked and auto-closed. Of course, if it's been closed for two weeks already, that's likely a moot point.
Thanks! Haven't seen that paper, I'll check it out. I think quantization only helps with inference speed if the network is running on CPU with negligible gains on GPU (Tensorflow only supported CPU on mobile last I looked which was a while ago). However your app is already super fast so don't I think anyone would notice if it was marginally faster at this point!

Regarding visible spectrum observations, I've been waiting to see if anyone can come up with a way to develop a consumer-accessible instrument that can sample a high enough resolution, to image all of the moon landing sites.

For as long as I can remember, the same thing has been said about the surface of the moon, which is the primary fuel for hoax narratives.

With all the buzz about high-resolution arrays being cobbled together from current-generation megapixel digital cameras, I'd love to see someone pull this off. It'd be pretty cool to know that for a budget of maybe tens of thousands of dollars, and some software skills, it'd be within the reach of hobbyists to snap some legit photos of the original moon landing artifacts as they exist.
Don't know. Never heard about it till today. Looks like this https://itunes.apple.com/app/apple-store/id933117605?mt=8 is the only IOS implementation
At a certain level of firewalling you bring the disadvantages of NAT. For example, if you block all input, or even just HTTP(S).
> At other websites, developers have very little leverage. The people pushing for bloated websites are managers / executives, not devs. Hence, bloat.

I found that AMP helps a lot in that marketing/exec teams see Google pushing AMP and think they need AMP.

My company built AMP equivalents, and honestly I wish we could ditch our entire React site for AMP.

Instead of an exec demanding a feature, we can now say "AMP doesn't support it." No matter how many times we've set performance budgets, management absolutely tears the budgets down the second we need to implement some flashy new feature (which for some reason is the perceived solution to every sales slump). A group of us has tried to use data against this at least a handful of times, but memories seem to be short lived.

Of course we need organizational change, but after pushing a stone up the hill over and over again you essentially just say "fuck it" and let it crush you. Bottom-up corporate change is a fool's errand.

This seems like an apropos place to shill my own p2p instant messaging protocol implemented in Rust: https://github.com/zacstewart/comm

The readme doesn't do it justice. It's actually very functional if I bothered to document how to use it, and I have a working GTK-based frontend that works well too.

tl;dr: Its network architecture is loosely based on the BitTorrent DHT. Each node forwards a message as closely as it can to the intended recipient, who upon receiving it issues an ack back to the network.

Yet to be done is providing some mechanism for "proving" your identity, integrating libsignal for encrypting messages, and much more.

I'm trying to get it to show HN-tier so that I can solicit help working on it.

NAT is not security at all.
I think this question can be best answered by first looking at what research tells us about learning (otherwise your question attracts only anecdotal responses which will be less universally applicable). Here's what research says, followed by how it applies to your questions in particular.

1) Mastery based learning is generally the most effective process (learning each axiom of a topic to 100% before moving onto the harder topic)

2) Spiral based learning is an effective add-on to mastery based to keep you remembering the things you've learned (coming back to a topic just at the point of forgetting keeps you retaining knowledge)

3) The content you learn off of (video, text, etc) has different attributes which may correlate to better transferring of knowledge: Shorter videos, hand-written visuals, enthusiastic voice, have all been shown to correlate with better learning outcomes.

4) The motivation you have for the topic you're learning and how much closer it exists to intrinsic/extrinsic motivation dictates how well you'll absorb a topic. The closer to intrinsic, the more effective learning will be. Project-based learning generally falls into this category: projects that interest you motivate you to learn more.

Now with all of that in mind, to answer your questions:

> Do you focus on one topic/book/course/project/article at a time, or split your time between multiple things?

(1) would suggest that you should not split your time, at least at first, unless you are trying to find a better explanation (3)

> Do you use any tools to track your resources, todos, notes, or goals?

Most of the suggestions sound like meta work. I wouldn't suggest tracking todos so much as perhaps writing down the things you've learned to prove to yourself of (1) mastery or to come back to later for (2) spiraling.

> Are there any pain points you have while learning, or are there any tools you wish existed?

Sounds like you are trying to make a tool to help people learn/track learning at a high, abstract level. Because there is no one right solution to everything because of (3) and (4), whatever tool you create may not actually help anyone unless it's more domain-specific and less abstract.
So why did the latter win?
"to throw money at it" is a general expression for the solution to overcommitment, schedule conflicts and resource exhaustion.
>> to avoid confusing establishments that were subject to the minimum with those that were not, the authors did not include large employers with locations both inside and outside of Seattle in their calculations.

I read this to mean that the study therefore would exclude employers such as Seattle-based Starbucks, Seattle-based Amazon, Seattle-based Costco, Seattle-based Nordstrom, McDonald's, etc. Based on that reading, it seems like quite a leap to draw any conclusions from this data.

Am I reading this incorrectly?

Then why are they doing NAT?

Edit: Although moving to NAT might push innovation too, or at least some clever hacks. Speaking of that, if you want use a relay to do NAT traversal then is TCP over ARQ (on UDP) as bad as TCP over TCP?
Wanting to see how "a feature that we needed" works is better phrased as a "solution". It solves a problem you have. The quote your referenced is simply saying that a large feature set is not the most important thing; whether it solves your problem or not is the key.

What other payment method would you propose? To me, credit cards are the least risky, because chargeback exists. ACH/direct debit is scary as hell; if you are a business you have only 24 hours to notice and halt a fraudulent/disputed charge (consumers have 30 days). And if you think Facebook customer service is bad, PayPal is even worse; not to mention that you must either choose to keep a balance with them (which they may freeze on a whim) or allow them to direct debit your bank account (see above).
Indeed! If anyone needs to feel the squeeze for IPv4 to make a move to IPv6, it is AWS... which MIT is conveniently selling the IPv4 addresses to!

Looks like the "credible" report is an approximation of a series of guesses and omissions. Measuring economic impact of almost anything is difficult but this one seems more vague than usual. If you want to discuss overall impact, you can't simply leave out things that are hard to measure but still wind up with a solid conclusion.
