Doesn't really apply. Oil companies exist because we buy oil -- both directly (fueling our cars) and indirectly (buying produce shipped from South America or clothing shipped from India). Saying "oil companies shouldn't have good IT solutions" doesn't really help anything.
So take them into public ownership. Then their strength can work for everyone instead of just some billionaires.
Specific situations which make for a majority of their market? I don't think "specific" is an honest word here when it's mostly standard per continent.

Their fraud system is one of the best in the world, but of course it will have false positives. You know that your anecdote is not applicable to the business in general.

What upfront costs do you have? Where are you based?

I maybe get your point but I think you're vastly underestimsting the difference between a tech company optimizing digital transportation vs. A local cab company hiring a consultancy to make them a white label app.

The key in your explanation is "without any middlemen". It's really easy to build a system that lets you send tokens to other people with low transaction costs: just trust someone to run a central database of all the account balances. This is how you can trade Team Fortress 2 hats with virtually no fees or settlement time, for example.

What blockchain ostensibly allows you to do is create that system without having to trust anyone to run the central database. But why would Coca-Cola ever need to do this? There will always be a trusted central party who can maintain the Coca-Cola bottle production database: the Coca-Cola company itself.

They are supposed to do an existing brands search--which starts with the no-cost-to-the-user registered trademark search provided by the USPTO--before consciously designing a defensible mark.

That means no one in your category or nearby categories is already using it, and it isn't already a one-word generic term.

A term like "backcountry outfitters" is more defensible together than either word alone, but still isn't very good, because it describes a lot of existing business. Selecting just "backcountry"--a dictionary word--as your whole trademark is pure madness. It's analogous to claiming "zymurgy" as your trademark and sending C&D letters to every micro-brewery in the US, ordering them to stop using the plain dictionary term for what they do when describing what they do.

Examples of defensible trademarks would be "Goatsbeard Gear", "Spelunkatorium", "Voyageur's Choice", "Trailhead Traders", "Avalanchador", "Rockspider", "Backwild Country", "The Hinterlandery", "Boondock Swamp Charters".

The point is generating a unique, distinct, memorable, and non-confusing term.
Eh no one wants to maintain and check all that old stuff or support people who bought something 10 years ago. If it works then great, if not then keep an old system around with that setup that supports it and make contingency plans when it inevitably fails.
> Blockchains are just a datastructure

Again, wrong.

> proof of work is not a strict requirement. I believe the rising popularity of Proof of Stake blockchains will make that evident.

I thought for a second whether I should include PoS and other schemes, but decided (wrongly) that nobody would try to squeeze imaginary internet points out of being willfully misunderstanding.

But so be it: proof of stake is a different mechanism that fulfills the same role as proof of work in blockchains.
Total tangent, but this reminds me of the old Windows 95 joke: 32-bit extensions and a graphical shell for a 16-bit patch for an 8-bit operating system originally coded for a 4-bit microprocessor by a 2-bit company that can’t stand 1 bit of competition.

Real paper, I think (from the linked principal researcher): https://research.chalmers.se/publication/511209/file/511209_...

The claims are reduced somewhat:

> The system features several attractive properties, such as a long energy storage half-life (40 h) at room temperature,

> Concerning the energy storage efficiency, 0.88% of the solar energy could theoretically be stored in a neat sample (S5, ESI†). The highest efficiency that can be expected for a 5104M solution is 0.02%, and for a 2104M solution is 0.01%

> However, the reaction rate was still too low to be used for macroscopic heat release purposes

This isn't a commercialisable solution. What this is, is fundamental research. Which often looks completely terrible because it's a first attempt at something. Once the relevant quantum effects are more understood, better candidate chemicals can be developed.
Yeah. Hoping they do produce more PineTime dev kits, as Go can now be compiled directly for it (via TinyGo) and a friend has a good project in mind it would suit.
> The Laplace Transform, on the other hand, decomposes a signal into both its exponential factors (decaying or rising) AND its sinusoidal components.

I want to clarify something a tiny bit misleading about this. In general complex exponentials are not orthogonal w.r.t. the relevant inner product. You can't really think of them as independent components that compose a function.

If you think of a function as the impulse response of a linear time invariant system, then the laplace transform of that function tells you the result of an experiment where you drive the system with an exponentially damped sinusoid. This is why the poles of the transformed impulse response tell you about the stability of the system: those are the inputs that cause the system to explode!
Three months is a hilarious joke. The value of analytics data decays steeply; they let you delete the stuff that's not particularly valuable to them.

If Google actually cared about your privacy you'd be able to delete the info for shorter intervals, or even have it not stored at all.
Good! Employees should have a say in how their labor is used.

Employees of claw hammer factories are better off not knowing what I do with their products in the dark of a Saturday night. Let's just say I'm not hammering nails.

OTOH, claw hammer factory workers are making a product that is legal to manufacture, legal to sell, and the intended use for said hammer is also entirely legal. You will find few protestors at the gates of the Stanley Corporation because of what folks might do with a hammer or a screwdriver. After all, they're really just trying to make tools for folks to build a nice dog house for your new puppy. And we all like puppies. Did Stanley just take on a big contract to supply the tooling for the construction of a new ICBM plant? Somebody got that contract, why didn't I hear about the protests?

To me, this just sounds like folks that are itchin' to protest something, and this is all they could find. Google's not making ICBMs here. If one feels strongly about the issue, do what I've done in the past and quit. ("You didn't tell me the DoD is your only customer.")
I hear what you're saying, but to be clear, Pine Microsystems is not operating a pizza shop. It is much more like a hackerspace or community workshop then a merchant. They offer a direct-from-manufacturer business model, where a non-membership based community of interested stakeholders directly contribute to most if not all of the products. Check out the engineering blog posts.

If you are looking for a turnkey solution, not all of Pine64's offerings are able meet your needs (but do snag a $1.99 CH340 Serial console.) and if you preorder the "Braveheart" phone, there is no stable off the shelf OS prepared for it. You cannot buy this and mail it to ahead your hotel and give a demonstration to the board by next Thursday.

That said, and I don't think this is superlative at all, Pine64's efforts currently exemplify the internet dream of a "Global Village" economy.
If you spend a lot of time reading and writing, a 4K monitor with a diagonal ≤ 28" is a good pick. The switch from ~ 100 ppi to ~ 160 ppi feels like a vision correction akin to new glasses or contacts.

With the aim of filling both central and peripheral vision with screen space, I use 3 × 28" 4K monitors on a triple VESA mount (EasyMountLCD EZM 002-0020). Having sufficient screen space for /everything/ related to my current task feels like it reduces pressure on my short-term memory.
NIMBYism is terrible, and so is whataboutism.
Thanks for being the only reply so far to attempt to actually address what I asked.

I have some critiques of what you've linked; I don't put much stock in the "I turned out fine" school of thought, for one. But it was an interesting read.

Striving for the "impossible" is something we do all the time, as hackers. It seems to me like the disagreement is not over whether one can achieve an impossible standard of justice, but rather, over what is impossible.
It would seem the issue is with low incomes rather than with Dollar General.

Being "sick of politics" is a political position, in fact a pretty conventional and traditional one. It means that you are content with the status quo and would rather people didn't rock the boat. In other words, you want to be comfortable.

People who protest and write letters raise issues. Some of the issues being raised have to do with our very survival (climate change), with facilitating war and with total surveillance. Maybe you believe these worries to be exaggerated, and this is your right, but then you must be willing to argue. You can't just shut people down by saying you are "sick of politics", that is not how free societies work.
REI is one of my favorite stores in the world. It's hard for me to come up with a reason not to like them.
This is a well-written post, although obviously carrying some confirmation bias against the idea of a cryptocurrency.

I'm also obviously biased, but if people are interested in my opinion (and only my own) here it goes.

> Libra’s byzantine tolerance on a permissioned network is an incoherent design.

There are two aspects here that the author seems to forget:

* The next best system, that a consortium of very different companies (think from different countries) would agree to run together is probably a protocol like Certificate Transparency which would be too slow and would have no mechanism to prevent double spending. If you're not doing this, then you're probably using a protocol that doesn't tolerate faults and the first time you have a fault your protocol collapses. There's probably a reason that Venmo cannot talk to Paypal which cannot talk to Square.

* Libra will eventually move to a permissionless setting, which means it has to be designed from scratch to support this evolutionary change. You can agree or not with this, but this is the way it was planned.

> Libra HotStuff BFT is not capable of achieving the throughput necessary for a payment rail.

Two things again:

* The number of people in the world who uses GBP vs the number of people who will use Libra at launch is probably not comparable. This means that Libra will be perfectly fine to carry the load for a number of years.

* Current research has shown that the largest throughput improvements are hidden in layer 2. If you don't know what layer 2 is: basically you do transactions off-chain, with whatever protocol you have, and only sometimes do you confirm the current state on the chain.

> Libra’s Move language is not sound.

I believe the type checking (and other checks) are done by the VM, (but that's not my domain so I might be wrong). Indeed, why would you trust the compiler to do the right thing?

> Libra’s cryptography engineering is unsound.

There are two things in this section that are completely wrong:

* No, dalek is not the "wild west” and is actually written by some of the few people who you could trust to write such a library. Yet, audits are planned. Also: we do actually use formally verified code! We have integrated fiat-crypto (a formally verified library, not a cryptocurrency :D) into dalek in order to use formally verified field operations.

* Neither do we use VRFs, bilinear pairings, and threshold signatures (they are just experimentations at this point) nor are these new tools or techniques. I don't have to say much at this point but I would take the author "It should be assumed this entire crypto stack is vulnerable to a variety of attacks" with a huge grain of salt.

> Libra has no capacity for consumer protection mechanisms.

Of course, it is a financial backbone, not a financial service.
Do you have any idea how expensive drugs are? I assure you nobody is spiking people's food with them.
yeah, well (and this might be a stretch for you to consider) maybe they reduced the return window because people like you expect every item to last indefinitely.
Yeah, on the surface that stuff always sounds nice because "see, I can run this thing from 20 years ago and I didn't have to do any extra work" sounds nice, but that also means it hasn't been maintained for 20 years...

I'd rather have planned deprecation and make choices to (at some point) abandon certain APIs, features and formats. In the case of formats, a public release of some parser code would be nice, so that if someone really wants to get some old data, they can, but other than that, stagnation isn't as good as people make it out to be.

In reply to the flagged reply:

1. While the Constitution of the People's Republic of China does protect religious freedom, this is only under the condition that the religious beliefs in question do not disturb the social order, cause bodily harm or obstruct the national education system. That means in practice, people will be detained for beliefs that are considered too extremist.

2. Would you believe me that they exist if I called them "education centers" instead? Try searching for 教培中心 in http://www.xinhuanet.com/politics/2019-03/18/c_1124247196.ht... It is described quite clearly that people can be brought to these centers even if their extremist beliefs do not otherwise amount to a crime.

3. I specifically brought up "杨永信" and "豫章书院" because they don't involve minorities. I didn't mean that they were mainstream in the sense that most people would approve of their methods, but there's definitely widespread concern about students spending too much time on the internet and too little studying. It's just that most schools take a less brutal approach to the problem and confiscate their student's phones instead of using torture.

Given your statement that

> Many Chinese people hope the government put an end to "杨永信" and "豫章书院", but I don't know why they don't.

consider that many Uyghur people hope the government put an end to the conditions in those "education centers" and don't know why they don't.

4. Do tell me if any of this is unconvincing. I'm still working on an airtight argument that is acceptable for someone with the perspective that the CPC is trying to do good in principle.
This is a cool attack, but I'm not sure where you got "$14" from. The laser pointers were $18 for a pack of 3, but you need a separate laser driver like the $300 one the authors used, and probably an audio amplifier as well.

Its really tough to quantify and comparison of the outcomes could be wildly different depending on your point of view.

I know having packages stolen is frustrating. I shipped cookies to a friend in NYC and they were lifted. It sucks, but were these people really harmed? the goods were presumably replaced (some of which were sloppy joe sauce multipack) and the people claiming they didnt feel safe and had to move were still there after writing a letter saying they had to move to the judge.

I also understand the residents point of view, you feel less safe. and that can be harmful to your psyche and mental well being.
The people I see driving around in Tesla (or large Audi/Volvo) here aren't really rich, more have a decent job and a willingness to spend a substantial amount of money on a car.

I don't understand it personally, I prefer cycling and having my mortgage paid off but everyone to their own :)

I guess if you're in your 50s then you paid very little for your house so it makes sense to pay the 1200 EUR a month net for a car.
No shit. Good price. Thanks!
It does, though. Refusing to assist with the destruction of our planet slows down the destruction of our planet. Why would I want to work to make these companies more effective?
Exactly this. The article somehow skips from "the grocery store closed" to "we need to open a new one" with almost no attention to what would be different the second time around. (If I may be cynical, the extensive focus on co-ops and community markets makes me think the reporter assumed the old grocery stores just weren't sufficiently profitable, and didn't ask whether they were even solvent.) It has one line which invalidates almost all of the other commentary: "In town after town, people said their greatest challenge was enticing their neighbors away from dollar stores or the Walmart four towns over."

There are lots of things worth talking about here. The way low incomes push people towards unhealthy diets to save money. The tradeoff between lower prices at chains, and more money leaving the community. The loss of indirect social benefits which don't show up on a balance sheet. Even the physical and mental effects of more time spent driving.

But reducing the discussion to "the town needs a grocery store to open" misses all of the most interesting questions.
I can think of a few reasons

1) Geopolitical - if there was a widely accepted, regulated global currency that is relatively non-volatile, pegged on a basket of assets, I think many countries would gladly do cross-border trade in that rather than USD. I don't think Libra will be it, because it's perceived as being Facebook coin. But an effort from central banks could be it.

2) mainstream programmable money doesn't really exist, neither do microtransactions, or access to the financial system for many of the world's poor
Agreed. As the original article said, stand-ups are useful in a run-up to a release. If you're releasing every week or two, a release should never be far out.
Sure, a company can be pressured successfully. But if a company allows political pressures to distract it, it will not thrive.
Politics is for Power, Not Consumption: how social media is warping our politics
Whataboutism is sometimes a good way to point out rank hypocrisy.

I didn't vote for Trump and won't, but I totally understand why he won. He won largely by taking traditionally Democratic counties in the Midwest who are fed up with having their jobs sent to totalitarian countries in one-sided trade deals for the benefit of huge corporations. He also won because people look at the coastal "blue" cities and see unaffordable enclaves of the super-rich, not some kind of egalitarian paradise.

They also hear it in the rhetoric. The worst example was Hillary's "deplorables" comment. Yes I know that she meant Nazis, but a ton of people heard "poor and working class." I also must point out that while the Nazi types are noisy there are not really that many of them. Trump could not have won on their support, but he did win with the support of a ton of disenfranchised poor and working class voters.

Note that many of these people hate conventional Republicans as much as they hate Democrats. Trump was viewed as the outsider "fuck you" candidate, basically as a walking Molotov cocktail to toss into DC. "I hope he does as much damage as possible" is one quote I heard from a friend who lives in Ohio. I also read a lot of comments framing the election as Trump vs. Bush/Clinton, seeing Bush and Clinton as interchangeable "establishment" names.

BTW I take whatever opportunity I can to call out NIMBYism. My favorite quip: Texas is more liberal than California because in Texas a poor person can afford a home.
Seems like Facebook's strategy for dealing with their PR problem is to blame someone else for the flaws in their product as a diversion tactic.

It's not a good sign when FB is unwilling to take responsibility for the mess they've made. How can anyone trust this company ever again?

Unfortunately, I think if they can win the PR war then they'll probably be fine. At this point the only thing that matters is public perception, and the one thing FB has going for it is that many people don't even realize that Facebook, WhatsApp, and Instagram are all the same company.
I don't know if they make any money at $99, but holding price steady can increase margin over time if the underlying costs go down over time.

Depends on your use case and operating systems. Are either/both of the monitors high DPI? Do you want thinks to look 'sharper' or do you want more screen real estate.

It also depends on which operating system you are using. Scaling on Linux is pretty terrible so I wanted a monitor that had ~100dpi so that no special scaling would be required. I also wanted the screen real estate of 4 ~22" monitors, so a 43" 4k monitor was perfect for my use case.
First there were two operating systems Classic MacOS and Next.

Apple acquired Next and they combined some parts of classic MacOS and NextStep to create OS X.

Apple then stripped OS X down, got rid of some Mac specific parts, added some new frameworks to create “iPhone OS” and introduced the iPhone Initially they claimed that the iPhone was “.running OS X”.

They introduced the iPod Touch later the same year and the iPad 3 years later at this point, they renamed “iPhone OS” to “iOS”.

They introduced watchOS and tvOS as more variants of iOS. There is also some iOS variant running on HomePods.

Over the years the two operating systems have both somewhat diverged and they still share both some old code and new code between the two.

This year, they renamed the version of iOS running on the iPad “iPadOS” as they started adding more iPad specific features.

They also introduced the “Catalyst” framework to bring iOS specific frameworks to the Mac to make porting from iPad to the Mac easier.

Finally, they introduced Swift UI as a common cross platform framework for watchOS, iOS, macOS, iPadOS and tvOS.
Except it isn't. There's BTC, BCH, BSV, etc. that are all forked from bitcoin, and there is an ever-growing number of tokens started from scratch (ETH, LTC, etc.). There is an infinite supply of crypto tokens.
