My last job we were 100% hosted on Heroku and coming from managing hundreds of EC2 instances and databases via autoscaling, CF, Puppet and home-grown scripts, it was a dream to use Heroku. We simply didn't need any operations staff to manage infrastructure, maybe a few hours a week for 1 developer out of 11 to adjust or verify a few things.

Need a bigger database? Just a few Heroku CLI commands. Bigger web servers? 2 clicks. Want a test database to run queries against? 1 Heroku CLI command. Want to test a branch of your code against the staging database? Automatically done via GitHub PRs, with DNS setup too.

We had 0 downtime in a year due to actual Heroku issues, developers could push code easily (git push), databases were backed up automatically, servers auto-scaled, etc.

I was genuinely amazed at how well it all worked. The amount of operations work was easily 10x less than if we had to run our own infrastructure on AWS due to not just the hosting, but the tooling. Deployment, rollbacks, slave database setup, configuration management, access control, log aggregation, 3rd party integrations and more.

Heroku does have some drawbacks, request queuing is one of them, mostly due to lack of clear docs and information. Even with its flaws it still saves a massive amount of time and money. For nearly all startups to medium sized companies I'd highly recommend using Heroku.

Well yeah not the average household obviously but if you really wanted to get rid of your dependency on the grid it would be somewhat possible. As opposed to say drive a at least 70 HP ~ 50 KW car. Not a proposal for everybody of course but for lets say political idealists.

As far as the 3kW kettle is concerned having a battery to provide for these surges is entirely viable.

Land is not the same as oil commodities because oil must be discovered and drilled, whereas we already know where all the terrestrial land is, and for the most part it is all already owned by someone.

Oil rights are a kind of land, of course, because that is what land really is... the rights.

Those rights are precisely quantifiable in the form of land titles. The scope of those titles, and the quantity of land subsumed under them, is precisely quantifiable and does not change from year to year.

The speculative holders of the rights are often neglecting to rent out the land, but in economic terms they are just consuming their own imputed rents. The rents are a flow that continuously accrues to the title.
I really like full-text search for books. Currently I use:

- Safari Books Online: expensive, and only works with books on their platform

- Recoll: libre/free, and can search a local book collection. Built as a desktop app, although there's at least one web client[0]

If either LibreRead or one of the Recoll web UIs can match the speed and UI of Safari's full-text search, I'll be very happy.

Eh, it also doesn’t make sense since Hanford is a waste storage site...where else could the waste be going, and even if it’s high grade, why does that involve the Pacific Ocean rather than a trip to Utah or neveda in the other direction? I’ll assume that whatever it was, it was unrelated to Hanford, more likely something to do with nuclear submarines or the training reactor they had at UW.
It's pretty much the same as in other languages, so don't over think it. The main difference for you will be Go is compiled, so you have to think slightly differently when writing tests.

Here are a few don'ts:

- don't take interfaces as arguments unless it really makes sense, even if it makes testing easier

- don't use one of the tiny test helper libraries that basically just writes if statements for you

- don't start writing tests until you've already figured out how to organize your logging and errors

One pattern I found helpful was to write an adapter that uses the testing.T.Print* functions as the destination for log.Print* statements in my regular code so that log messages aren't jumbled when running tests in parallel.

I would guess that the creators and proponents of this idea don’t see it as merely providing solutions to technical issues with UBI. This idea is much more than “a standard UBI proposal except using blockchains.”
Jeez, you're completely missing the point.

The GP was asking for a comparison the odds/cost of mining a coin with the odds/cost of winning the lottery. Not about "investing," and not about "making a profit."

I think a lot of the difficulty is in the build system being federated. This makes it complex as it supports multiple build other systems for other ROS packages. I haven't looked into it much yet, but I'm curious about ROS 2 also supporting ROS on smaller micros now. I think this would make the build system more complex.

Modifying the how the devel space is handled seems like an improvement and making it more modular seems like it should help though.
That sounds a little too magical. Solving the identity problem is the biggest challenge here.

Why you are still using it then? Operating systems are very complicated beasts, none is perfect but I like Linux the most. There are issues too but I feel like I have more control over it.. Sometimes work reasons force people into Mac/Windows though... :(
That's great.

I suggest it's probably not a huge factor for most people.

But there's a huge amount of information embedded into culture - ideas, mannerisms, forms of education, language, social strata - it goes far, far beyond 'language and cuisine'.

Large scale immigration wipes that out and does not replace it with a new culture, rather, a 'globalized' set of values - and a Starbucks on every corner.

So in the interests of having actual 'diversity' on planet earth, because as of today we are witnessing an 'extinction event' of culture, we might want to consider the impact of some of our policies.

Immigrants (and FYI I've been an immigrant at stages of my own life) are mostly just regular people, and so we don't want to play into the hands of xenophobes or 'racial purists' or whatever, but at the same time, we have to recognize the imperative of culture itself. Is all.
This was interesting to me because it re-iterates the one of the lessons of The Innovators Dilemma: doing what your customers ask can be dangerous.
All sorts of wrong in the linked article - the source is dubious at best.

"“The same way, ISIS was created to counter the Iraqi stance, which did not agree to blockade Syria, was against no-fly zones in Syria and against American military bases.

"The Iraqi society is against foreign military bases on the country's territory coming back to Iraq and setting up bases here."

The Iraqi official also claimed that it was the country’s military that were mainly responsible for driving ISIS out of Mosul."

> Is there a base number of participants that are required?

Well, the money has to come from somewhere. If you have a homogenous group, all with the same income/wealth, then UBI would do nothing. You'd give everyone the same money you took at tax time. No net change.

You need a group of people with diversified income/wealth. The wealthier contribute more than they get from UBI, the poorer contribute less (if any) than they get from UBI.

I like it mainly for the idea of replacing welfare with a much simpler system. But it will never happen in America, land of absurd tax code complexity. And certainly not with a name like Universal Basic Income. It would have to be called something else to avoid triggering people.
Extremely interesting.

Some AI literature is of the belief that consciousness emerges from imagining hypotheticals. You could probably describe a few key milestones.

..

.. - Imagine your 'self' in relation to these other entities, all capable of imagining each other's actions.
Impressive. An important point here seems to be that these ASO's have a chemically modified backbone which prevents degradation by exonucleases. But the bases are un-modified allowing complimentary pairing and activation of RNAse H activity. Even so, I'm surprised they're able to cross the cell membrane in high enough quantities to have therapeutic effects.

I see what you're saying, but you haven't convinced me of this disbalance. What incentive do sellers have to accept AliceCoin over HomelessCoin if everyone adheres to this 1 to 1, even though de facto this is not the case if you consider economic resources?

> Since this system enforces a 1-to-1 exchange rate, can you name any practical difference whatsoever between Alice trusting one of those people for 1 coin (i.e. they'll be able to trade with someone in a scenario where that someone will get 1 AliceCoin and Alice will get 1 Homelesscoin) and simply gifting 1 AliceCoin as charity?

The key difference is that she has lost no value if everyone holds to the 1 to 1 always. This is an important distinction, you're right. However, I don't see any incentive to break from 1 to 1 if everyone is holding to it. If the grocery store accepts HomelessCoin, I have no preference for AliceCoin. If everyone breaks from 1 to 1, then you suddenly have to calculate and consider the value of billions of currencies now. Who wants that? What value do I get out of that change?

This coin is inherently built upon the idea that we are not tying individual coin value to someone's economic value. The seller should just want more coins, and it doesn't matter who they come from.

I didn't do many, but outside of the first couple, I didn't notice any that had attainable answers without computation.

Bunn coffee maker. Makes a unbeatable pot in 3 minutes flat.

Same way they make drip dinner coffee - water is heated to just the right temperature, unlike a Mr. Coffee which is too hot and sours the coffee because it uses the steam as a pump.
I think a lot of work has been undertaken for a ROS1->2 bridge. It should be feasible to use this to have ROS on a micro and bridge to an existing ROS 1 code base.
I'm with you on this one. My french press outperforms pour-over, Aeropress, Moka pots, and a bunch of other methods when it comes to properly extracting coffee.

I'm particularly sensitive to the bitter flavors in coffee, however, so I really don't like so many coffee making methods which produce bitter coffee.

Carbohydrates is a term that groups sugars, starches & fibre together. There are simple carbohydrates (breads, cereals, desserts and other man-made carbs) and complex carbs (fruit, veg, whole grain foods)

Simple carbs are broken down and consumed very easily, complex carbs take longer to be absorbed and energy is released over a longer period.

A good rule is to eat things as close to their natural form as possible.

Most products have been processed in some way before eating - cleaning & packaging being the simplest.

However baking, frying, adding excess sugar/salt, preservatives, additives, etc happens in a large amount of products that we don't realise. It is astonishingly easy to consume these products to excess (muffins, donuts, bread, potato products).

Frozen food / microwave in 2 mins is not actually bad for you. You can get bags of microwave rice or veg that are perfectly healthy (check the ingredients).

A good place to start is getting familiar with where certain foods are in the Glycemic Index.

In terms of improving your own diet and improving energy, just make simple substitutions. Swap fries > sweet potato, or white bread > whole grain wraps, or chips > nuts & seeds.

> The claim is pretty well known: Below a certain threshold, money is the most important thing. Above it, it is not. This is very different from the extreme pacifist mindset. The equivalent would be: "There are certain circumstances where it is important to kill another. Outside of those circumstances, it should not be the primary means."

The claim is horse manure which is why it includes no numbers for the threshold. My number matched his claim. Except that the claim is not what was meant. What was meant is "if I'm compensated well into six figures then the other things matter more than incremental dollar".

The article is describing how to peddle low salaries + magic pixie dust as a way to swindle the candidates to accept non-competitive offers.

That's ok. I do not need many friends. Especially if I have to accept as friends those that claim 'oh, it is excellent' when in reality they mean something else.
At home I usually use a cheap electric grinder (I don't even know the name right now, I got it from the parents' place since they weren't using it) along with a gooseneck electric kettle for pour over[1]. Every now and then I use a moka pot. On the go I usually get macchiatos. I see others mentioning French press; I tried that for a while but I always ended up either too watery or too oily.

It's pretty simple really. The price would drop precipitously and start a selling frenzy as people try to preserve their investment.

Unlike the exchanges, you can't close down Bitcoin if there's a run on the "bank," And unlike the banks, Bitcoin could only recover based purely on market forces.

Well, to be sure, various governments could step in to control the cash exchanges, but that is far more difficult with e-coins.

It would actually be fascinating to watch (from my perspective), because without the possibility of central banks or governments stepping in to control the bleeding, we would see what an entirely unregulated market would do in such a circumstance. It would certainly give the economics PHDs something to write about.

The validators idea to accelerate bootstrapping is a good one. And I think you're right; it be institutions like companies and banks that will provide the validation services.

The issue is tying this to a non-fungible asset. The most obvious problem will be ghettoisation. You can envisage "invitation-only" validators at one end of the economic spectrum and a state sponsored validator at the other end.

You could, possibly, force them to interact by mandating a common intermediary, presumably the state, so that there are connections across the population. But, at that point, the personal asset/currency idea seems superfluous.

Might as well be an account linked to, say, your social security number that mints a fungible asset periodically. You can look at enhancements to the SSN idea to make it less forgeable but that's a separate issue.

Having said all that, I've been quite skeptical of the social benefit of UBI. Largely as I couldn't see how you could sensibly start from here, as it were, and control its development. I still can't see how to do that but I'm less skeptical that it's possible.
I'm not sure what the exact house edge is on Powerball. But let's say it's 20%.

Due to dynamic difficulty adjustments, the profit for miners is just a bit more than the cost of electricity. However, this is only true for those who have the best specialized mining equipment and the cheapest electricity in the world. For an average person living in a typical area, even with dedicated equipment, you'd probably be far under breaking even. Most likely much less than 20%.

And that's with specialized equipment (costing thousands of dollars). With your home computer, it'll be hundreds of thousands of times less efficient per watt of electricity to mine bitcoin. Even for other cryptocurrencies that might be resistant to specialized equipment, you'd still most likely be over 10x less efficient.

Go with the powerball tickets.

For me it comes down to ease of use. If Spotify didn't exist, I doubt I'd be buying albums etc. anyway.

It's the same as torrenting movies, people do it because it's convenient (and free) but now Netflix is here, it's even easier than torrenting. So that's why I'm subscribed to both services and have been for many years.

So artists that leave Spotify, like Taylor Swift for example. I may listen to their music because it's in the charts, but when she left Spotify I just didn't listen to her music at all. So I'm sure Spotify do give the artists attention they would never usually get.
