>This isn’t what people mean when they imply liquidity. Needing consent and being able to demand cash are different domains.

I don't understand what you are trying to say here. You don't need "consent" if you want to wait the 3 days, but if you get "consent" from your counterparty you can get it instantly. 3-days is about as fast as ACH. But if you want, you can feel free to open channels with shorter locktimes if needed.

>Or lost 90%. We had this in the era of free banking, i.e. pre Federal Reserve. That history is one Bitcoin is presently replaying.

But you can't lose money if LN is working correctly. The whole idea is that you sign the transactions saying "if this is broadcast under these conditions, you get all of my money" when you open the channel. It's literally not possible to fractionally lend on LN, because all money MUST be there, and signed, for you to use it.

I've had conversations with you before, and I'm fairly sure you don't understand the basics of Bitcoin as you keep repeating these things as fact, so I'm going to stop replying here. Please make an effort to understand it before you start denouncing it. Or at least explain why you think these apply to the conversation in ways that someone like myself who isn't well-versed in traditional banking systems but understands Bitcoin technically will understand.
I don't think the blockchain is a good technology. Traditional databases or something like Git solve the same problems better. I have an ideological desire to see more trustless and peer-to-peer systems and I think they'll take hold eventually, but at the moment blockchains are worthless.

Its worth noting that, from a brief look, the "cognitive training" program looks like a fairly intensive and detailed course, not some brain-app-like game. I don't know if I've seen something similar offered commercially.
I have close to 2TB of valuable data. By valuable data I mean anything that I put work into creating: photos, documents, projects (code), etc. Also anything I would have to put work to re-create: collection of music not available from other source than my CDs, for example, as it would require me to go through hundreds of CDs to recreate it.

I am using mostly a system of 4 4TB naked hard drives and a hard drive docking station.

One hard drive is always far away containing full backup of all systems.

Two hard drives are at home in rotation and they will be containing full backups. From time to time I will take one of them and replace the drive that is far away and bring the far away drive to my rotation at home.

One hard drive is dedicated to storing increments. This is mainly for convenience. If I happen to delete important file or a file that I worked recently on I have it available most probably as I do backups continuously (4 times a day) using a script.

I am using Acronis True Image on Windows and a bunch of scripts under linux to store the backup on the drive.

Obviously they have to put in more energy than they get out as per the law of conservation of energy. This is really not likely to compete well with batteries and EVs in terms of efficiency. Its only useful if the government distorts the market with incentives or where the energy density of the produced fuel gives an advantage over batteries (maybe if they produce jet fuel for planes?) I'm dubious that this could ever work for vehicles more efficiently than batteries.

What drives me the most crazy is that after decades these tools can’t get the basics right, like text editing. That has to be the single biggest waste of time.

I always prepare my material in a real text editor, until I’m completely satisfied with the content, before I risk dumping it into PowerPoint or another terrible editing environment. I mean, 99.9% of presentations contain bullet points and it’s still a mystery what will happen the next time I type a key: will there even be a bullet in front of the next line of text, will it just invent a new line spacing different from the previous bullet, etc.?

Then, as if to punish me for having the audacity to save time composing text outside of Office, its Paste mechanism utterly destroys text in ways that almost seem malicious.

I end up having to find and disable so many settings just to restore a reasonable set of behaviors for stuff like Paste (bad defaults).
I've experienced this with two different paypal accounts I created specifically to use with steam after they stopped accepting bitcoin payments.
In some cases, the certifications associated with some score on a test do matter. It's one thing to pursue a certification, whether some IT certificate or passing the bar, for the learning experience and personal satisfaction. In those cases, it may well indeed make sense to conclude that you came close enough and move onto the next thing.

But if you've spent 3 years in law school and really want to become a lawyer, it may well make sense to study harder and try to pass the bar the next time--especially if you didn't fail by much. (Don't actually know how much feedback if you get if you fail.)

This is not a common thing. This is only going to happen in high crime areas. Full building access control is a necessity if you are in an area like this. Locking the bathrooms is not a good solution.
You raise a really interesting perspective. I look at this as optimist versus pessimist perspective. Not achieving something can be considered a failure to one person and a learning less to another, glass half empty or full.

I have personally struggled with this and it makes me wonder if there is a particular way a child grows up that places them on one side or the other. Is it parenting that creates this perspective or is it life experience as a child such as not getting picked for a team or not being first chair in band.

After 30 years of life and achieving what I consider career success I wasn't sure I was capable of I have identified my pessimistic attitude as a fallacy in my personality. Constantly I am trying to change it but it can be really tough to not focus on failure and identify the positive's of events that don't turn out as planned.

> Well-paid middle managers with no design skills take far too long to produce ugly slides that nobody wants to look at. They also file their own expenses, book their own travel and, for that matter, do their own shopping in the supermarket. ...it is partly bad organisational design: sacking the administrative assistants and telling senior staff to do their own expenses can look, superficially, like a cost saving.

Not just superficially -- it is a cost savings, and a net benefit to society. It's the realization that slides can be ugly and still get the point across just as well. And doing my own expenses when everything's charged to a company card takes all of 5 minutes for a weeklong trip.

This means we can free up talented designers to improve mobile apps used by millions instead of presentations seen by ten, or administrative assistants to work where they're most needed, such as in health care.

I also don't know where the author gets his claim that average productivity growth has been negative since 2007 -- a chart here [1] for the US shows it's been positive for 18 of the past 21 years, and the average is clearly positive too. And while there are certainly plenty of theories as to why productivity growth might be decreasing, the idea that it comes from ugly presentations not only has zero supporting evidence, but seems almost laughable.

#1 isn't strictly true, you don't need to be "always online", only online at some point within the locktime (normally 3 days right now).

You can also hand your "revocable delivery" transactions to a 3rd party (or multiple 3rd parties) who can monitor and broadcast them in the case of cheating, but can't actually spend any of your money themselves.

So you could have a group of people watching the blockchain always online that can punish non-compliance, but you yourself are only online when you want to transact.

The idea behind Dark Puzzle was to experiment with a user interface that focuses on voice instead of graphics and visuals, so I thought that a memory game is a good fit.

Also, one of the main design goals was to make it as much accessible as possible for vision and hearing impaired players and offer them a similar experience as all other players.

So I'd like to hear your thoughts about the game, how to improve it, and how much you think it achieves either of its goals.
Some societies seem to focus more on individual success than community survival.

You could call them that if you want, but they are significantly different than traditional banks.

I was talking about Lightning Network nodes, not Bitcoin. Bitcoin at one point was at this stage but through iterations and continuous improvement it evolved to being able to secure all those funds.

The point is that it's disingenuous to deem a new tech dead, while the engineers working on it sill say that it's not yet fully-ready for production.

The implementation and the protocol still evolves, but the core idea behind it is rock solid and the most promising way forward to help with scaling AND enable use-cases that would be otherwise impossible (see microtransactions & realtime millisecond scale monetary transactions etc.)
Only for some code it's not apples to apples. For most code GC is not a big deal and the languages just offer different tradeoffs. Perl, for example, has XS for performance critical code, which is essentially C or C++. But the ecosystem is big enough that you don't necessarily need to write any C code yourself.

And all of this is not even relevant to usability issues he tries to discuss.

Security issues, most likely. Like Firewire, Thunderbolt suffers from the same security issue in that to achieve its high speeds, it gives connected devices direct memory access. In other words, any connected device can read and write directly from your RAM, bypassing any kind of access control built into the OS.

I understand your point, but the goal of technology should be to help us be more productive, not to try to separate the ones that have strong willpower from the rest. The clear trend here is that technology companies want people to become slaves to whatever process they setup, instead of working to improve our lives.

The carbon tax (and cap-and-trade) is the right-wing think tank alternative to reducing emissions by regulation, much like the individual mandate/Romneycare/Obambacare/ACA is the right-wing think tank alternative to single-payer/Medicare for all/universal health care. The issue is that the right wing think tanks come up with these alternatives, and then the right wing labels them as a left-wing attack upon America.

Increased wealth comes from an increase production of value in the world. It is not a one-way street, one gains wealth by contributing to society. A single person's work can provide jobs for thousands. It can increase the production of food/housing/etc which helps millions of people. Or reduce millions of hours used in one area to free up human capital to focus on other areas, etc, etc. It's entirely possible for individuals in society to contribute far far more than they consume and set up systems which helps future generation contribute far more and at a faster rate than previously possible (ie, via investment in education, economic support systems, access to capital/banking, etc).

There's no reason why increased individual consumption can't be sustainable or a ultimately net gain in society despite their increased individual consumption (by their own productivity, contribution to taxes, economic contributions, social work via charity, etc).

This is what is so often overlooked in people's efforts to blame 'wealth accumulation' as the underlying problem, as if it only benefits that one person. Resulting in policies trying to reduce "wealth inequality" that ultimately end up hurting everyone (including the poor) in a 'noble, well intention' effort to punish the rich.

The government and volunteer groups are the primary bodies that needs to address and coordinate many of those social and economic issues.

The biggest problem with India is that:

a) the taxes/government organizations are wasted and terribly corrupt which hurt both economic growth for the middle class and small business [1], where only the powerful/connected are allowed to operate in an efficient business environment and social policies make little progress

b) countless individuals exploiting this corruption and contributing nothing to society (ie, rewarding people despite not contributing any value to the economy) by leeching off these public institutions either by getting friends in gov to do their bidding or more directly skimming off public funds

c) big longterm social issues can't be addressed with an ineffective government, a private/non-profit industry constrained by endless bureaucracy and top-down political influence, a healthy middle class and safety net (where the majority of the population can't live a sustainable lifestyle out of pure necessity to eat/live).

d) the smartest people needed to lead those non-profits and government agencies all leave to North America and Europe - driven away by the government incompetence, leaving many mediocre B-players in leadership positions within India, further contributing to government failure - an evil cycle.

I was in a WeWork for 2.5 years. Our floor had four phone booths but probably 20 or more people whose entire workday was spent on the phone, which led to multiple people pacing the halls while on a call. No amount of gentle reminders, glaring, or fighting back with my own noise would stop the loud conversations on the other side of the single-pane glass door.

There was a similar problem with the capacity of the men's bathroom.

WeWork should take more care that their physical infrastructure is not overwhelmed by subtenants who are mostly alike.
If you want to buy a keyboard, then you visit sites from where keyboards can be bought. Meanwhile, when you are doing other things, you shouldn’t be seeing advertising, least of all ads specifically targeting you. You seem to find it hard to understand that ads are aesthetically unacceptable to intelligent people. Do you see ads on the pages of a novel you are reading in a paper book?
Agreed. My father owns his own business. My grandfather helped him after it failed 2-3x. My father however, "did it all by himself". Bootstraps and whatnot.

He was lamenting to my brother a few years ago that he has no legacy. Well, you fucked over everyone in your family, including your kids to get yourself ahead. So yeah, you'll die rich and unloved. Surprise outcome!
The reputation and sales risks of false positives are what concerned me. I'd probably not do it for that reason. I think Windows XP Activation was the first time I saw anti-piracy features go really, really bad for all kinds of paying customers.
I am surprised that "add carbon taxes, cut income taxes" doesn't take off. Income taxes distort the economy, so lowering them is a massive benefit - if they can be replaced with another, better revenue source.

A carbon tax is an infinitely better revenue source as it reduced externalities.

I think rather than focussing on emissions reduction, global climate talks should focus on a global carbon tax, offset by reductions in other taxes.

(It's somewhat ineffective for one country to do a carbon tax now. Past a certain point it will just send carbon producing activities to countries without a tax. A globally agreed tax reduces this.)

A tax would be the mechanism to reduce emissions. Absent such a mecanism, emissions have only grown, despite accords to reduce them.
There’s a lot more I could know about the practicality of blockchain but the value of the technology is still more real than the currencies that live on it.

WeWork started in 2010. If they aren't making money after 8 years, then they aren't pre-revenue at a $20,000,000,000 valuation but scammers. Every other lease company says these types of rentals are lucrative, so why aren't they for WeWork?
I thought that those insane transaction fees and processing times were due to technical decision to use too small block size, and to hashing algorithm used. But I'm no expert on technical side of Blockchain so I might be wrong about that.
Yes - but in that user's case, it wasn't a rhetorical question. The gay coworker post had examples of some gay people he worked with he didn't approve of, and he vehemently argued in the comments, too.
That is true! The biggest downside with channel factories is that noncompliance from one party forces the whole factory to close and reopen without them, which gets much more likely with every added participant. But if there is only one participant which is "untrustworthy" (on some level, in the sense that they aren't trusted to stay online as much as well known nodes are), then the system could work fine.

That's really interesting, and opens up a lot of ideas. Still, I think we should avoid trying to bring up channel factories for now. They are still a few steps away as they add more complexity to an already complex system. Focus on getting LN up and working, then add in nice-to-haves like channel factories slowly once vendors are on-board.
