... And Bitcoin got the segwit upgrades that fixes the transaction malleability issue, enabling users to make new types of contract transactions like payment channel and lightning network transactions, which Bitcoin Cash specifically refused. One thinks it's evolving by tweaking constants, and one is working on enabling new things.

Lots of companies don't actually want "rockstars". I know someone from college with incredible quantiative and programming skills. He started taking rigorous college level math classes and writing his own compression schemes in high school. He got his undergrad degree in about 2 years by getting permission to enroll in 4+ graduate computer science courses each semester instead of doing the normal curriculum.

When he got hired to do boring tech work at the company I worked at, he just freaked everyone out. The questions he asked were too pointed and he would just do things correctly instead of doing what his boss said. Since he was extremely gifted and had offers to work at other (better) firms, threat of job loss didn't mean anything. All his managers basically hated him.

"Seal holes in foundations of
buildings or entrances to rat
burrows with a minimum of 2 in.
(5 cm) of reinforced mortar mixed
with iron filings (from machine
shops) or broken glass pieces
1/8 in. to 1/2 in. (0.3 cm to 1.3 cm)
long. (You can put some glass in a
tough paper bag and smash it
with a hammer. Shake out the
broken glass pieces into the
mortar as you are mixingi t.) The
glass or the filings deters rats from
digging the filled holes out again
before the mortar hardens."

I learned so much solving problem XXX so is it okay to publish my solution elsewhere?

It appears that you have answered your own question. There is nothing quite like that "Aha!" moment when you finally beat a problem which you have been working on for some time. It is often through the best of intentions in wishing to share our insights so that others can enjoy that moment too. Sadly, however, that will not be the case for your readers. Real learning is an active process and seeing how it is done is a long way from experiencing that epiphany of discovery. Please do not deny others what you have so richly valued yourself.
Wouldn't it be better to just adjust the linter, refactoring etc to work on a multi-repo hierarchy? Most of them already mostly do.
That is... until you try to remove a submodule.

I like sobmodules, but the whole feature needs a lot more polish before it's widely adopted.
Why do you need webassembly for that, since this game already works great right now?
Why the downvotes? This is a valid discussion topic.

I recently went on a date where the girl told me she nearly had a panic attack when she couldn't find me on Facebook or anywhere else while waiting at the venue. Given we had met briefly at a bar only a week before the check was warranted (IMO), and given the positioning of Facebook in her life and many others, it was the tool she relied on and was disarrayed by.

Sure my case is anecdotal but I do not believe it is unique. Facebook has forced itself to be a single point of failure in parts of our culture, they did it intentionally to make money, and we should acknowledge it.
I would love to see a system for flagging or downranking posts and/or threads that are beating a dead horse - by somehow recognizing similarity with a critical mass of past posts.

This is cool. As someone out of full time education, and who dropped maths relatively early, where’s a good place to start learning some of this stuff? By stuff I mean things related to algebra and whatever the black magic I quoted is
I like this idea but project Euler seems to focus much more on math than programming languages so it makes sense they don’t retain all answers.

I would really like to see something similar for actual programming challenges though. Some real-world examples, maybe with predefined test cases that you then solve and optimize for CPU/Memory/Time/lines/whatever.
There aren't good ways of making a decentralized cryptocurrency that scales its minting/inflation rates with its current market value (what specific market is the "decentralized" software coded to trust?), so unless a cryptocurrency exactly predicts its future adoption/demand rates and fits its minting schedule to that, then it's very unlikely to give only "reasonable-sized" returns to its early adopters.
Maybe unrelated, but one of my favorite sayings is "moderation in all things, including moderation".
I think it's hard to split the difference. If there was a service using RackHD to spit out cheap bare metal it'd be more doable to run on top of that, I think.
I thought the original idea of Bitcoin was to be a currency and make fiat money obsolete. The finance industry is simply acknowledging that it’s a speculative asset and mostly interesting for its volatility, something that fits well within its longstanding frameworks.
That is one of the goals of neovim. And it's even being put to the test: The VSCode-vim team is indeed working on a neovim integration.
UN official touring Alabama's Black Belt: I haven't seen this in the First World
Ask HN: I want to start an ISP, where do I start?
Hello Hacker News, I'm a software developer with a handful of years of experience in developing software in a corporate environment who was extremely frustrated with the blatant monopoly I saw in my parents home town when I went home for the holidays, currently they are paying $70/month for a 10Mbps/1Mbps connection, while I'm paying about that for 5 times the speed in a major city and they (and most of the surrounding area) have no choice but to pay it.

I want to do the math and research on how I could found a competing ISP ... Where do I start?

Where do I start learning about internet infrastructure? I've a vague idea that I will need to talk to an upstream provider and work out a deal for some amount of bandwidth

Where do I start learning about the regulations I'll have to follow and make sure my paperwork is correct and filed on time? I've a vague idea that I'll probably need to incorporate and invest in a good lawyer/accountant

Where do I learn about everything I'm not currently thinking about learning? I want to offer solutions, not just complain about the status quo, so please enlighten me.

Thanks in advance!
That doesn't add up. I can't tell if it's an author with an agenda or just a bad tax plan.

So the author wants us to think that single people will be more or less the same.

Couples with children taxes will increase the amount they pay?

Couples without children will get the tax savings?

Does anyone know more about this on HN?
>That is a preposterous way to compare poverty between countries.

My guess is it's a quick way to compare while factoring differences in the cost of living. The idea is that the absolute differences between the countries might not mean much given differences in cost of living, so you compare relative difference inside a country. I can't defend it vigorously, but that's my guess.

>Our child mortality and life expectancy are conflated with a large immigrant population and the existence of an underclass. If you equalize the results for diversity, America does just as well as the other developed countries.

"Hmm, if we cut out of our statistics the points that draw it down, it will bring our average up." That seems like cooking the books. Shouldn't we include those who bear the brunt of externalities in society? Is that exactly what they are looking for here?
Top 20 Funny Christmas Quotes That Never Outdate – Cisdem
There is an effort to make everything hermetic. Namespacing is hard, but not always possible, and touching production servers (and potentially crashing them) could cause significant revenue damage.

I don't think all tests should be hermetic - the effort to make such things happen usually do not overweigh the time it takes to do them, but hey - that's what we are doing.
I appreciate your good nature in taking the time to engage in this silliness but I have a hard time believing your high school teacher or anyone else taught you that. The wikipedia page on it:

"In English writing, quotation marks are placed in pairs around a word or phrase to indicate:

Quotation or direct speech: Carol said "Go ahead" when I asked her if the launcher was ready.
Mention in another work of a title of a short or subsidiary work, like a chapter or episode: "Encounter at Farpoint" was the pilot episode of Star Trek: The Next Generation.
Scare quotes used to mean "so-called" or to express irony: The "fresh" apples were full of worms."

Even 'direct speech' is at odds with 'verbatim quote' and that's the first thing there. Direct speech can be completely made up.
I know people like that, and I think I've been that person before at my first job. I would argue that someone with great quantitative and programming skills who "freaks out" their coworkers is not a rockstar. To be a rockstar developer, you have to have good enough communication skills to work within your team.

A rockstar developer wouldn't ask questions of their coworkers that would embarrass them; a rockstar developer would phrase questions and concerns in a way that the other people on their team could understand. A rockstar developer wouldn't do something contrary to what their boss said, they would explain why would do something a different way before doing it (or explain why it's better). Now, if coworkers or management are too incompetent for even that, sure, even the best developer would have a bad time.

Part of being a rockstar developer is, in short, knowing how to work with developers who may not be as good as you. I've been there before and while it can be tempting to use that opportunity as a way to establish hierarchy (sadly important if your company stack ranks) by asking technically challenging gotcha questions and showing off how smart you are, it creates a toxic work environment and disrupts other people's work. It's much better to help people grow and not to overwhelm them with technobabble

Even something as simple as being able to have a clerk fill my jar with a weight of instant coffee would cut down my recycling mass by an average of about 50g per week and eliminate some plastic. Glass doesn't have a limit on recycle phases if handled correctly but all plastic other than PLA has a pretty short recycle lifetime.
That is not a sharded blockchain and shares the same fundamental restriction: all nodes must verify all blocks.

Not my moral judgement, I think the creator of bitcoin was quite explicit in his (or her) disapproval of the finance industry and governments inflating the economy by injecting large amounts of money, and went on to create a currency with a fixed supply. It is ironic these futures are effectively leveraged bitcoins, needing central trust. I'm pretty sure Satoshi would not approve.

That said, I do question the value of cash settled pork belly futures when you are not going to buy or sell any actual pork belly in the future. If I were to write tax law, I'd tax it the equivalent of casino tax, at least.
I'm a supervisor at UPS, so maybe I can offer an opinion (this is a throwaway account).

I'm not sure if there is anything analogous to the US Department Of Transportation in England, but we have to abide by pretty strict rules here in the USA regarding driving hours. A UPS driver cannot work over 14 hours on a shift, must have 10 hours between shifts, and cannot exceed 60 hours in a week without (IIRC) 38 consecutive hours before the next shift. That being said, we HIGHLY AVOID working drivers over 12 hours per shift, and try to take on a lot of extra help during the holiday peak season so that the work is distributed evenly.

From what I can tell from the article, these are probably inexperienced drivers who may be on their own in regards to organizing their delivery route, sorting packages on their vehicle, and learning their route. Because UPS has a centralized management system (as apposed to FedEx, for instance, which is contract based), we monitor every driver and can send other drivers to assist anyone who begins to struggle.

Its not unheard-of for UPS drivers to pee in bottles (and less often, poop in big plastic bags that are kept handy in the package cars). Its definitely not encouraged, but it happens, especially when you're on a rural route.

UPS drivers have it pretty good because of the collective bargaining that's available through the union. We're definitely going to have some rough days ahead of us for the next few weeks, but peak season is a big deal that we prepare for months in advance.

Yeah why? Why would you publish strictly an answer key, with no solutions or discussion when the site itself, a well known and cherished part of the software development community has explicitly requested that you don't?

9 of 10 people my age have it [1].

Facebook provides a public log of years of your posts. A quick way to get to know someone. To figure out if you should trust them. It's far from perfect but neither are social security numbers.

This article is pretty blatant flame bait... Statements without evidence abound, like:

> At the same time, the EU hopes to pass a law that will effectively render the act of carrying reasonably large sums of cash — say, anything above €1,000 — across borders enough to get it confiscated.

Or even:

> No, the measures are aimed at average Joes and ordinary Janes, and the main objective is to further dampen their ability or willingness to use or carry cash.

Statements that are intended only to provoke an emotional reaction have no place in responsible writing.

I think the consensus in the bitcoin community is that it won't have any effect and Bitcoin will continue chugging along as it has.

It was mainly the bears saying the futures would increase shorts on bitcoin.

Can't imagine anyone in their right mind would short bitcoin right now though...
Any arithmetic book on Sequence and Series will provide you with the basic toolset to derive the above.
Amusingly enough, renewable power operators would be a good bet. If Global trade collapsed then they'll have an enormous advantage over fossil fuels because they don't have to import coal/oil/gas from across the globe.

> If I invest in agricultural companies in Greenland, what protects them from being pushed out by Spanish agricultural companies that buy up land in Greenland? That would especially suck if I shorted the Spanish companies.

If the world get's messed up enough that Greenland becomes an important source of agriculture then you'll want all your investments to be local.
If you read the first paragraph of the website, "Although mathematics will help you arrive at elegant and efficient methods, the use of a computer and programming skills will be required to solve most problems."
I know you said you're in Canada, but for anyone else reading this in the United States, Gemini and Coinbase are widely-available and dependable for transfers in either direction between Bitcoin and USD. (Maybe they're available outside of the US too, I have no idea. It's a shame that it's apparently so hard to make transfers between countries with the regular banking system.)
This is my thinking. The volatility of bitcoin is insane and fascinating. It’ll be a real experiment if futures flattens it out.
But it DID work. For the majority of human history, gold and silver ran the world.

Economic predictions about how society would collapse if assets were used as currency is provable false. As proved by the fact that the global economic world chugged along just fine with such a currency.

The benefit is the miners are fungible. If one miner wants to enforce unusually high fees or restrictions on what kinds of transactions can be sent (such as which countries can send funds between each other, etc), then it just means that if that miner mines a block, some transactions have to wait an extra block to get mined by a miner without those extra restrictions. And it will be more profitable for that miner because of the extra transaction fees, so in practice miners don't impose extra limits.
What happens when a customer who really does have a modem that is vulnerable or outmoded runs into related issues? Is that customer going to accept "Well, we included it with our junk mail" as an explanation? As for email, does anyone use their ISP-provided email address anymore? Everyone has a third party provider (mostly Gmail).

I don't think there's any fault in logic in presuming that the best way to make sure a customer receives a notification is to insert as near to their known-active stream as possible. I don't condone altering that stream, but I think it would be nice if they could send a page, potentially at the browser or OS level, exclusive for system control and status messages (no sales, marketing, billing, or collection messages allowed).
I do not have an formal math education, but I'm fairly sure what you quote is part of the Arithmetic Progression concept (the sum formula more specifically), so taking a look at the arithmetic branch of math might be a good idea.

Hardware wallets like TREZOR are pretty cool for enhancing security (it can also act as a U2F key). A seed is generated in the device and represented by a list of 24 words; your private key never leaves the device.

However using the same word list (which you back up on paper) you can recreate the seed and derived keys on software that uses the same key derivation standard.

Actually now that I’ve typed that all up, I agree with your initial point. For the average person setting something like this up is still a huge hurdle. It does offer some protection against a hack for the more technically comfortable.
