Lignin from hemp could be a possible bitumen replacement:

https://gizmodo.com/a-compound-from-plants-could-replace-bit...

Looks like hemp is 5-30% lignin depending on the type, with female hemp having roughly double the lignin content by dry weight:

Also algae oil can be converted to a bitumen-like tar with roughly 55% efficiency, so if we assume the best algae is 50% oil by weight then we end up with about 25% tar by weight (I can't find confirmation of this, so they might mean 55% tar from algae directly):

Perhaps these could be combined with recycled plastic to make an asphalt derived purely from biomass and recycled materials.
Iceland has some heavy industry like aluminum smelting which requires massive amounts of electricity. The energy consumption is also including private households. Meanwhile Ethereum is handling currently less than 1,000 users in its core business: dApps.
Thanks daug. You too.
You’re just moving the problem though. The sites won’t get chargebacks, the groups selling the coin to consumers will.

Buy it with another crypto currency? Problem moves one step down the road again.
I agree with previous poster. You will never be able to rent out machines cheaper than the cloud platforms without making a huge loss.
> The transfer itself does not require trust. That's the value.

Don't you need to trust nodes that they'll pass down and/or include process your transaction, and that they'll do so in a timely fashion? Which seems just like trusting that, say, your bank or the Mastercard servers will process your transaction properly? Not to mention the more mundane aspects like the fact that you still need to trust that your ISP won't cut off your access to the network, etc...

To me the value seems to be that nobody can forge a transaction based on your currency (or whatever it is you have), not the idea that you somehow don't need to trust anyone when you do transfer value.

Those neurons are arranged and incentivized cleverly. The structure is also very important and is necessary for the resulting intelligence.

So it's not only computational power, but also the unique structure nature found through trial and error.
Pff, don't get me started :).

My approach has been, for about the past decade or two, to spend a lot of time, energy, and possibly happiness, on figuring out how to blend in and be inoffensive. I'm not entirely sure it was worth it, but at least I feel it's allowed me to be my 'authentic' self without being dismissed in many situations, so that's something. And there are even times when I feel validated, which I think is quite valuable. We're social creatures ultimately, most of us anyways.

Considering my uncertainty about this approach, though, I shouldn't be lecturing others!
1. What if we put "beginning" as in "before it was even called the Internet"? Indeed, ARPANET, which came online in 1969, saw fast growth in the United States in the 70s. Nodes came online to use it, not to make a quick buck. The government subsidized it because its potential use was obvious. Email started being used in 1972, FTP in 1973. To compare these world-changing technologies that were invented and used merely 5 years after ARPANET came online to CryptoKitties, which is the most useful thing to come out of a decade of work on blockchains, is a joke! And it's barely funny!

2. Of course the effect on the environment will continue to be pointed out: Ethereum's energy consumption is growing and the use cases are nowhere to be seen. So far, "plans" in the cryptocurrency space never go as expected. Satoshi didn't expect persistent forks and altcoins, for example. Vitalik advertised Ethereum as a "world computer" but it can barely stand when only 14k users are trading cartoon kitties on it. He also said Ethereum's "code is law", until he changed his mind and forked the network due to a hack. Please excuse skeptics for holding accountable those that do not have a history of consistent and successful results.
Another commenter answered succinctly, but for the next time a side project can be evaluated for viability by also calculating estimates for fixed and marginal costs & doing more competitor research. Has always helped me.

Visual perceptual skills updated by process similar to memory reconsolidation
Wow... this is pretty much the core component of that class. I wish I had access to this after the assignments. Not having access to working code after we were graded so that we knew what was wrong was just horrible/painful/depressing. To make matters worse, the next assignment did build on that. Helplessness.

I did comment in my end of class review about it, but the forum feedback was pretty much 'it had to be that way' so the next cohorts did not have access to it. I was not the only one pleading for working code. I was happy to get a poor grade as a reflection on work submitted, but I wanted to learn how to do it right and that opportunity was not afforded to me.

I still did not get access at the end of the class so I hope this site helps me fill in the knowledge gaps that the course refused to do.

Give the developer a simple task that is work relevant and 24h.

If the person does it in 5m using some fancy trick, then you know they're a problem solver of high calibre. 1h-5h: They are probably adequate. 24h: junior or bad.

Ask them about the trad offs they made. The 24h guy may not have made any, and may be the perfect maintainer. The 5m guy must have made some. Ask for their reasoning.

It may be the reason to hire them. It may be the reason not to.

Innovator's dilemma
I don't get it, could you please explain it?
Liberty Village is a moderate failure to encourage local culture, and the only reason it's not bleak and desolate is the historical Village area to the west. CityPlace isn't a community so much as it is a way of fitting the maximum number of concrete boxes into a given space as permitted by zoning laws. Culture wasn't even a consideration.

Compare with the King St. W. projects where the buildings try and augment the community instead of stomp and supplant it. These new buildings have created opportunities for new businesses to take root and thrive.

Despite having a considerable population, it's slim pickings around the condos in CityPlace. Unless you like Starbucks, dry cleaning, and an astonishingly boring pub you're out of luck.

Thanks! aside from being informative, your comment gives me quite a number of specific terms to google :).
> a way to filter for 'wealthy' people that can afford to lose the money

The part I didn't appreciate is it's also a filter for people who can hire a lawyer/adviser to conduct basic diligence. Raising $1 million in $10,000 cheques guarantees virtually zero oversight. That, much more than anything legitimate, has been what ICOs have enabled.
The world growing more complex from the software's perspective.

And by that I mean, it has to account for more scenarios or do additional things... unless your software is growing in complexity while you're only removing features...

Bugs in software come from thinking we're simplifying the world in one way though the program, while in reality it receives a slightly different picture.

If i had to take a guess, I would imagine above all else, the reasons people start drinking are going to vary from one culture to another (on the average).

Ive heard the expression: drunk people speak sober thoughts (meaning they hold back less)

People who get drunk to cele brate act different than people who get drunk to cope with something (from what ive seen)

If in one culture it was only socially accepted to get drunk to celebrate, i would expect different behaviour than a culture who only views drinking as a way to cope

Just my uninformed theory

So you actively seek out and work for companies that you believe are most likely pure scams? I don't mean this to come off as too judgmental, I'm honestly curious what your take on it is. Does the fact that you know your client is trying to rip people off factor into the decision to take on a project?

Or do you think the ICOs you design for are all well-intentioned and just so happen to all fail after/during their token sales?
Beers on "nitro" are still carbonated with CO2. The nitro is used to achieve a higher serving pressure used to force it through a diffusing nozzle on the tap. N2 doesn't actually dissolve in liquid very easily compared to CO2. If you put the CO2 at higher pressure, it makes the beer more carbonated over time.

> Browsh consists of a minimal Golang CLI client and a browser webextension. Most of the work is done by the webextension. When the CLI starts, it looks for a compatible browser (currently only Firefox) and starts it in headless mode. Once the browser has started it opens a remote debugging connection and installs the extension.

So a browser wrapper.
While I applaud the change in perspective into looking at plastic as a resource, not a curse, this article smells of BS:

> He received a patent for the process in 2006. Since then, almost 10,000km of Indian roads have been paved using his technique.

This sounds like random stats thrown around by government officials, particularly because later in the terribly-written article, it mentions:

> Nonetheless, at least 16,000km of road have subsequently been paved in the state of Tamil Nadu. The national government has since approved the idea and sanctioned at least 13,000km across the country to be paved in the material as well. Of this, 8,600km have already been completed, says Dr IK Pateriya of the rural development ministry in Delhi.

The numbers simply don't add up.

> Shredded plastic below 70 microns (including the multi-layer plastic shreds) is then sprinkled over it.

A shredder capable to shredding materials down to 70 microns is absurdly impressive, and would likely cost hundreds of thousands of dollars. Unless the article means that some of the plastic films being used have a thickness of 70 microns. Honestly, it just looks like the author read 70 microns in the source material and threw it in to impress without knowing what it means.

> A stone tile measuring one square metre has a manufacturing cost of Rs 100, approximately £1.. 60 plates would be sufficient to construct an eco-friendly bathroom, says Dr Vasudevan.

£60 to build a toilet in India, plus labor, construction, etc? This is a very bad idea. The median household income per capita in the poorest states in India is under $1000/year. Just the cost of the toilet is much higher than the median monthly household income of one person.

That's before we get into the issue of using cement and concrete in the "plastone", which are very carbon-intensive (concrete generates about 400kg of CO2 per cubic meter). It would be much cheaper, simpler and greener to use wood to build it, which can be carbon net-negative.
This seems like a very unfair reading of what the author actually wrote:

> One note about the results for kdb+: The ingestion scripts I used for kdb+ partition/index the data on the year and passenger_count columns. This may give it a somewhat unfair advantage over ClickHouse and LocustDB on all queries that group or filter on these columns (queries 2, 3, 4, 5 and 7). I was going to figure out how to remove that partitioning and report those results as well, but didn’t manage before my self-imposed deadline.
After abducting a humpback whale from the past and delivering it to an unknown spaceship, I say the prime directive is moot regarding whales.
> Your transaction is still being intermediated by an entity that can choose to appropriate your funds otherwise

The frequency of each of coins being stolen from wallets, being lost by exchanges or pilfered by ICO frauds is far, far higher than anything happening at proper banks. Blockchains are a neat technology which should have never been marketed as a currency.
Some people don't die from an illness that is considered a terminal illness and which receives euthanasia in the current medical practice. I can think of a few people who have survived certain types of cancer. Also it really depends on where a person is located right now. I could obtain euthanasia if I were to fly to Switzerland. I haven't considered doing that just yet and I don't necessarily find it the same as receiving the treatment in my birth country. There has already been a case where a person suffering Gender Dysphoria received euthanasia (not my country) and someone obtained euthanasia from traumatic rape throughout childhood (again not my country).
Hey man, it's still not clear. I would say "Nissan Admits Data for Internal Emissions-Test Was Falsified", because right now it seems like the data was internal, not the test.
Yeah, I guess when you think about it that way it makes sense. I think I might have assumed this was for production and not build environments.

Manhattan was "planned" inasmuch as the grid system was created, but the exact character of each neighborhood wasn't laid down in advance. Defining "planned" is a matter of drawing a line on a spectrum, so there's a lot of arguments possible here.

What I mean is to compare Manhattan, which was loosely planned, with Levittown (https://en.wikipedia.org/wiki/Levittown), rigidly planned, which was the original planned city and the grandfather of overly aggressive city planning. Later this evolved into the dystopian monstrosities envisioned by urban megalomaniacs like Le Corbusier such as Ville Radieuse (https://en.wikipedia.org/wiki/Ville_Radieuse) which would have been so utterly unliveable.

He honestly should have stuck to architecting open-air prisons and slaughterhouses.

Even Manhattan got bludgeoned by overly aggressive planning in the 1950s and 1960s when tyrants like Robert Moses were involved.

Creating great urban spaces takes a lot of patience, care, and most of all, a willingness to let the city grow as it wants to, not as you intend it to.

I think a CS degree would be helpful and is worth looking into, especially if your associates lets you trim off a few courses. Don't look to the degree to make you more marketable, rather, look for the deeper understanding of the math to help you solve problems that others can't.

If you're interested in being the person who builds the tools rather than using them, I think you'll find yourself going further with a degree. In addition, you may get more out of it because you're not starting from scratch.

Can someone explain why the chrome browser simulator is so bad. I recently had to do some web work, normally don't deal with HTML . Anyways I tried to use the emulate view to test against iOS devices. Had QA test on a real device and it was all wrong. Ended up just getting a virtualbox of osx up to run the stimulator.

Normally it isn't a problem using it but trying to line up slanted designs with pixel perfect placement wasnt working out at all.
if they resort to console.logs, they are just randomly trying things.

How does that follow? It's just another way to check the state of a program at a given point.
Chrome developer tools is just a godsend. Its so much better than any other debugger I've worked with, and miles better than firefox debugging tool

I personally use a chromium based browser called slimjet to do all of my development. It runs off v55 I think which is like 5 versions behind chrome. But its nice to have a dedicated app for debugging.

One tool that I find I use everyday is this: http://lab.maltewassermann.com/viewport-resizer/. It is WAY better than chromes native responsive webdesign tool.

When I first started developing I would always just go on stackoverflow and ask a dumb question. Now I consult my debugger and it answers everything I ever wanted to know.

Knowing how to use a debugger means I can reverse engineer html/css on any site too, so thats a big bonus.

There is no one size fits all solution. Data link latency is a real factor, but that can be mitigated by hard wired look up tables and some degree of AI auto piloting. In addition, the Military industrial complex has its mouth gripped tight to the Pentagon teat. As we have seen in past wars, the rise of fogies into upper echelons with archaic mind sets is a real problem. Losers fight with the past wars winning tech, winners do better.
Right, the mistrust creates the fertile soil on which these conspiracy theories can grow & spread. And I completely agree that we have massive legitimate cause for mistrust.

But they don't create & promote the theories, then weaponize the believers.

E.g., you and I don't watch the scams, then go out & produce videos about how the world is flat, jet condensation trail are chemical sprays to kill us all, etc., etc..

That comes from sources truing to manipulate & weaponize the ambient discontent.
Fun facts: ITU-T criteria for 4G is 1 Gbit/s nominal data rate. So LTE is/was 3G. LTE-Advanced, which has seen deployments in 2017/2018, can get to 1 GBit/s on paper. Android has a "LTE+" indicator for LTE-Advanced.

We do have imitation Learning. I think the article is missing some important parts in RL. One way to train a network is to use experience from others or even past experience of the agent, but why is it interesting doing it from scratch? Because doing it from scratch will allow us to face a lot more problems where we don't have any information or skills and because we avoid the bias in the data and we can discover new things (as it happened with AlphaGo zero with its 'tactics' in go). Now we have a method that can be applied to all the problems that are similar to a board game without any other information, just the rules of the domain.
