Leaders don't decide. They propose values (such as a block of transactions). There may be multiple leaders with different proposals and participants get to a consensus about which proposal gets accepted for a given slot.

You speak authoritatively, saying "this is a common misconception", but blockchain is a distributed consensus protocol and I don't think you are familiar with multileader and leaderless flavors of distributed consensus.
It's a gross oversimplification of what they mean. I don't see how pointing that out is "pointless pedantry".

YNAB is a personal finance philosophy. The software that enables that is secondary and could just as easily be a spreadsheet (and v1 was).

There’s a huge education component that YNAB offers of videos, podcasts, and live training sessions. A lot of that material is about how people can change their relationship to money.

For the people it works for, it can be truly life changing to go from living paycheck-to-paycheck to being able to accomplish things with money.

That’s why you see such rabid fans. They’re fans of the lifestyle, and they happen to use the software.
San Francisco's scooter war: city hits back as 'unlawful' schemes flood streets
They really need to redesign those with an obvious "nose notch".
Huawei's equipment is almost too cheap to be able to ignore it. Here in Europe most telecommunication equipment (DSL, GPON, LTE radios, CPEs etc) installed in the past 5 years comes from Huawei and ZTE.

I don't know whether Huawei and ZTE carry Chinese state backdoors in them, but if China had a plan to widely distribute equipment around the globe to be able to tap into any connection, it would have already succeeded.
These ledger programs don't really do the same job as a spreadsheet. You could do it in a spreadsheet, but it would be very difficult and error prone.

A spreadsheet is more of a general calculating device. I have rows and columns and I can do arbitrary calculations on rows, columns and various cells. A ledger is a tool for double entry accounting. You have transactions against accounts and you are trying to validate that the transactions are consistent. There are other kinds of reports you can do, but your main purpose is to ensure that there haven't been any errors.

I find double entry accounting weirdly soothing. "Fun" is not really the word to use, but it's a bit like fishing when you don't really expect to catch anything ;-). For most people double entry accounting for your home finances is overkill -- you probably don't care if you make mistakes because the consequences are pretty small. But it's kind of neat/cool/zen to do it anyway.

If you are running a company, or you have a large portfolio of stocks/bonds/etc, or if you are dependent on transactions in FOREX, then double entry accounting is usually a necessary tool. The downsides for screwing up can be massive (especially if you get your taxes wrong!) I have personal experience with the government handing me huge penalty fees for mistakes that my employer made with various things (stock options, etc). I never reconciled the books and so never noticed the errors. Perhaps that's why I find double entry accounting soothing now :-)

As a programmer, I find ledger/hledger/beancount to be the most convenient way to do things. My text editor is already an extension of my hands. I can use any version control I want. I can write my own reports using any language I want. I can write code to automate transactions and I can do it in any language I like. ledger and the like are really just file formats coupled with a validator and a few canned reports. Like I said, you could do it with a spreadsheet, but without the constraints of the file format/validation it will be pretty easy to make a mistake. Also it would be a pretty huge piece of code to write using spreadsheet macros (not that this ever stopped anyone before ;-) ).

Wow - I heard it was called JavaScript to cash in on the familiarity of the name Java, but I didn’t realize it was at the behest of Sun.
In my opinion Containers are the best thing in Firefox. I'm sacrificing battery life just so I can use them on my Mac.

The country that switched lanes overnight
Very cool, but really wonder what the durability is. Is it more like faux leather which might be used as an accent or is it something you could actually use structurally.
Yep, it can win you the Presidency. Also prior to Trump's win, he was a very successful salesman with probably the best in sales talk.
I tried to learn Dagger for a recent project in a similar setting (Dagger+Android+Kotlin). Spent some 8 hours, couldn't make it work and gave up. I suppose, as with most systems, one needs to build up a list of recipes for solving common problems. But with Dagger I found that notoriously hard for some reason. Perhaps because it tends to fail silently at runtime or with non-descriptive errors.
>The way we think of flu in the west is roughly similar to how Africans think of malaria: a pain in the butt but not the end of the world. Imagine what we would do if rich Africans arrived and started handing out face masks during flu season. We'd probably do what Africans do with malaria nets: say thanks and throw them in a drawer.

That's incredibly misleading, ignorant, and even disrespectful. First of all, malaria is a scourge that's not even comparable with common flu (even thought the latter, through sheer virulence, rivals the former in number of anual deaths). Secondly, you are absolutely talking out of your butt when you say "Africans throw our nets in the drawer"; much to the contrary, these sort initiatives are constantly shown to be one of the most effective ways to reduce malaria infections, indeed one of the most effective ways to prevent suffering in general.

Let’s say a home every 80 feet. That’s 132 homes per mile. Over 7 years that’s $40 per year. I wonder if it makes the neighborhood 10 cents per house per day nicer. I haven’t lived in the LA heat.
Over the years they have definitely fixed those one by one, but I’m not sure if they’ve fixed all of them. I believe the last problematic one I encountered was some ads-related developer console a year or two ago.
How can that be a case in point? Apple has been aggressively removing ports for years. See the floppy drive, non-USB ports in the iMac, CD drive in the MacBook Air, 30 pin connector...

Ask HN: How to securely send documents
I’m trying to send sensitive documents to a friend internationally. Friend is non technical. What is the best way to do this?.
Depends on how well it works. If it actually brings down the temperature a noticeable amount in the summer, it might be offset by the saved air conditioning costs. LA gets some fun blackouts every summer from everyone using their AC at the same time. As a resident, I don't have any problem with the experiment.
The barrier is high enough that I heard that Microsoft is working on this with UW by using pretend patient encounters in an attempt to bypass PHI and get a database.

Sure, sometimes these media campaigns backfire. I do think Hillary got more support than she would have without the billion dollar push, but it was still a poorly executed campaign and doesn't negate the fact that media campaigns can change people's perceptions.
LA is mismanaged today at epic levels.
I have to say, I find it remarkably ironic that a researcher developing surveillance technologies has this much concern over being surveiled. I'm also inclined to note that the argument "these technologies with obvious, profound antisocial uses have some feasible prosocial uses also" doesn't justify the work.

Having gotten that off my chest; you're probably worrying about nothing, at least in terms of impact on your day-to-day activities- if the U.S. or aligned nation started curtailing the travel of computer scientists, it would be all over HN for weeks. Maybe if you want to go work for your country's intelligence agency someday (an obvious move, with your interests) they might look over your file before an interview. But perhaps in that case, contacts with Chinese researchers would be seen as an asset- the CIA and similar organizations have been known to try to recruit cooperative foreign-employed scientists in interesting fields, for various purposes, and to use their own experts in those fields to make contact.

It might matter if you're a "real academic," i.e., affiliated with a university and conducting your research in "conventional" settings. For an academic to not be talking to out-of-country colleagues would look pretty odd, in most fields. But if you're just some dude in your basement chatting with Chinese espionage experts, that might raise some red flags. :)

Are you confident the majority of the gains weren't made in the first year? It's exactly my point that knowing when to give it a rest is hard to estimate, and those who work on these problems professionally are likely to just keep pushing, potentially just spinning their wheels. Interestingly, the brain keeps working on these problems subconsciously, so you can actually get more done if you work on more things and tend to give up a bit earlier. I've solved hard problems before in an afternoon, a year after being hopelessly stuck on them, and my sincere estimate is that I would have made exactly zero progress had I kept pushing.
Calling this a "new design ethos" ignores Apple's history. They've had their share of hard-to-use duds in the past, such as the puck mouse. And they have their share of extraordinarily well designed devices today: who would dare say that AirPods are "hard to use?"

I used to live in southern California, and LA is just hot. Always has been, always will be. $40,000 per mile to paint roads white is a waste of taxpayer money that could otherwise be used for more fruitful causes and initiatives (food for the poor, infrastructure, healthcare, housing).
I sometime think it would be good to have some practical entrepreneur training at school even if only lemonade stand type stuff. It would be more useful than a lot of stuff they do teach.

It’s a question of mindset, but often correlated with scale. A rich person is a successful car dealership owner who has a net worth of $50 million, drives a Lamborghini on the weekends, lives in an 10,000 square foot mansion, has a sweet private movie theater, and owns a 60 foot powerboat. His economic activity is focused on consumption. He wants to leave his kids enough money to be rich for life. I can’t give many examples because these people are soon forgotten, but Donald Trump was almost one of these guys until he got some new ideas late in life.

A wealthy person has a net worth of $100 billion, is driven around in a Mercedes S600, has a 120 foot sailboat, goes to private parties at Sundance, values their time above everything else, and is focused on his legacy and place in history. His economic activity is focused on investment. He wants to leave his kids with enough money, connections, and capabilities to become among the great American families, shaping policy and public life for centuries. Think Rockefeller, Carnegie, Gates.
You may be very right.

Yes, basically. Cancer is at heart localized evolution, and there are many, many pathways which can provide survival or reproductive advantages to cells or tissue if they become dysfunctional.

I wonder why countries like Taiwan and Korea are so good at building things like roads, metro railways, etc, while around Boston a lot of it is basically atrocious crap that comes at multiples, to orders of magnitude, the cost.

Edit: also in Hokkaido, I never saw a single road as bad as around Boston.
I use uBlock Origin to whitelist 1st party JS when I like a site, and Containers to keep the signed in riff-raff away from everything else!
Are they dealing with the same climate issues? The extreme hot/cold cycles really tear up Boston’s roads.
We used Zulip (then a commercial product) at FoundationDB, and really liked it. We had teams in two cities.

The threading, which they sell as the core feature, is nice, and does make it more usable for "important" conversations than purely chronological chat. It also makes it easier to screen out conversations you don't care about.

But IMO the killer feature is the "all messages" view that merges chosen streams in more or less chronological order. It makes it much easier to keep up with what you care about asynchronously without throwing everything into a single stream. And therefore it is easier to put down, and to use notifications very selectively, which mitigates some of the major downsides of company chat.

I haven't used Slack recently either, but as I understand it its "all unreads" feature is much clunkier.

I haven't used a recent version, but I would definitely consider using it again.
Is there an advantage to this over Chrome Profiles, a feature built-into the browser?

Ask HN: Which predictive analytics tools do you use and for what?
I'm a marketer, writing a post about predictive analytics tools, but I'm a little confused.

Here are some of my questions that I'd really love to read your answers to:

1. What does a predictive analytics tech stack look like? Which tools do you use for which purpose? Examples would be phenomenal!
2. Are there alternatives to the above tools for SMBs?
3.How much data do you need to have until your predictive analytics gets smart enough to predict things accurately?
4. What are the typical "triggers?"
5. What are some practical, lesser known ways to use predictive analytics in marketing/CRO? What can you do with these predictions?
6. Anyone think predictive analytics is BS? If so, why?

Sorry for all the questions. I'd really appreciate any and all insight or points in the right direction! =)

The role of proof of work is to make the creation of information one-way based upon a pre-specified amount of work. Therefore, in a properly constructed system, a participant cannot steal the results created by another party.

That makes no sense, or the meaning is at least not obvious. What does it mean to make creation of information one-way? Proof of work is just a vote allocation scheme. We want to reach consensus about what the transaction history is and do so by a majority vote and therefore we have to decide who gets how many votes.

This alone has no single obviously correct solution, for example, if I have a company with a company account, do I get one vote for the company or do I get a thousand votes because the company has a thousand employees? Or maybe votes proportional to the amount of money in the account? And if the system is anonymous it gets even harder because there is no easy way to know who cast a vote or if someone cast a million votes.

And that is the way in which I used identity, the identity of an entity allowed to cast a specific amount of votes. And that is what proof of work does, a collection of mining hardware establishes an entity with a voting power proportional to its hashing power.

Identification is generally accepted in the security community to come from something you are (biometrics), something you have (bank card), and [...] An identity is something entirely different from work. Proof of work, since it is one-way, proves that work was performed. This has nothing to do with identity, which cannot be proved by work.

As explained above, I was not using identity in the computer security sense but in the sense of the identity of entities with a certain amount of voting power. And all your other remarks essentially also hinge on a misunderstanding of my use of identity, if you read it as entities with voting power it will certainly make more sense.
There's a difference between a "theory" (in popular usage) and a "theorem" (in a field like mathematics).

A theory is a hypothesis. It's a plausible-but-unproven guess.

A theorem is a fact which is known because it has been proven.

I think that was the OP’s point. FB woule have geolocation information on you because thanks to someone else’s use of your WiFi network on their cellphone, FB can now associate your IP address with a geographical location.

So even though you’re on desktop and haven’t provided them with location permissions, they can still identify your location based on your IP address.
> But nonetheless, the experimental data that went into this discovery was largely non-reproducible.

I am finding a hard time to grasp what you are telling here. If you deduce a set of laws A from an event X, you don't need X to repeat to check the validity of A. You can check it against another event Y, where you predict its characteristics using A. If the laws are valid, the prediction ll match the actual observation..
Korea has even more extreme hot/cold cycles. Even Taiwan, in the mountains, gets cold/snowy in the Winter, and what I saw there was that there were zero roads as bad as in, and around, Boston.

Also, in Hokkaido I never saw such bad roads, either.
There was nothing but statement of fact in the original link, taking everything that everyone for saying at face value. Do we just assume that anything from Fox News is biased here on HackerNews due to its source?

If they manage to reduce the temperature by doing this, then it would help climate change by reducing energy usage during summer.

Slack eating into Dropbox's territory with (decent) file sharing / searching and Dropbox countering with a alternative chat/ threading app is a nice battle.
I don't mean to antagonize, I'm just offering another perspective. There are no doubt many different kinds of rich intellectual traditions around the world. Should we call them philosophy? Philosophy is a category of intellectual discourse invented in the west. The history of the term is bound to the history of the west. Why should we apply a western category to try to understand non-western thought? Isn't this imposing our own way of thinking about intellectual disciplines onto a culture that doesn't understand itself in the same way? It would be better to categorize these disciplines in the way they people from other countries understand them. Islamic thinkers don't draw a line between what we call "philosophical issues" and what we call "theological issues". Why should we draw that line when we read them?
