Even back when I was waiting tables in college in the 90's most transactions were CC. You had to enter the tip amount as part of your end of shift processes to balance things out. This was recorded by the system and you then had to enter it into the companies system. Essentially everyone only ever claimed the CC tips and nothing more.

Yet as more and more transactions move to CC the discrepancy between actuals and declared is MUCH smaller.
> In the case of direct collapse you have a big cloud of gas that just collapses into a SMBH as the galaxy is forming. In the case of accretion, the SMBH starts off as a collection of stellar mass black holes which then merge into an IMBH, which then accretes gas to become a SMBH.

Could you clarify if SMBH is shorthand for "Stellar Mass Black Hole" or "SuperMassive Black Hole"?

GiveCampus hiring full-stack and front-end engineers in DC and SF
GiveCampus is a Y Combinator-backed company that builds fundraising software for educational institutions. We're tired of schools being stuck with crappy software that never changes, and we're working to bring actual innovation to the space, and solve the hair-on-fire problems fundraisers face.
We're growing at an awesome pace, and now need more motivated engineers to help us build out the features and products schools want!

Michael Seibel, CEO of YC, expects us to be a household name in the next few years: https://news.ycombinator.com/item?id=13896296. We were also covered by the Washington Post last year (https://www.washingtonpost.com/news/grade-point/wp/2016/04/1...), and have more than 5x the number of schools using us since it was published.

We're still a small team, so if you're looking to join a fast-growing startup and have an immediate impact, we're looking for both full-stack (Ruby on Rails, Postgres) and front-end engineers with at least 2 years of professional experience. Our current team was previously with Facebook, Amazon, and Intel.

Please no recruiters or dev shops.

Reach out to careers@givecampus.com with a bit about why you're passionate about education, and a project you've working on that you're particularly proud of.
This is a common and easily available technology for residential and commercial applications. With a closed-loop system a 4-ton HVAC system requires roughly 600ft of 3/4-inch pipe as vertical wells. That typically means 4 wells maybe 15-20 feet apart. You need a decent about of property to support these systems, enough room for a well driller, appropriate drilling conditions, permits for drilling, etc.

There are other systems for people with the land which may be less expensive which don't require drilling.

I spent several summers installing these systems, they are surprisingly simple and effective.

One of the PITA aspects of this type of break is when library writers need to change (via hard break) their external APIs because Rust has made a "minor break that can be easily fixed".

For example, one of the timely traits had `min` and `max` methods, as it corresponded to a type with upper and lower bounds. Rust added `min` and `max` convenience methods to all implementors of `Ord` (which this type was), which now means that anyone who wants to use the type needs to use UFCS. Or, I issue a major break so that their lives don't suck (now `minimum` and `maximum`).

The Rust change was classified as fixing a "papercut", so that folks wouldn't have to `use std::cmp::{min, max};`, but it's a pain in the arse when it's done so casually.
HN absolutely does have narratives. The community here has several hot button topics that are not to be disagreed with lest you be down voted and/or flag killed.

Lots of unreasonable or toxic attitudes are expressed here daily, but couched in faux intellectual language that makes them appealing to a crowd that considers itself the internet's intelligentsia.
"Puts customers first" and "Puts ethical considerations first" seem to be at odds in my mind... in my experience "Puts customers first" translates to "employees are overworked and underpayed" which is a huge ethical concern.
You shouldn't. Since that's nothing close to what he says, you might just learn something by listening. Haidt is pretty fair and non-judgmental. If anything one could use his talk to say conservatives are using a more balanced consideration when making moral decisions. Using five factors instead of just two.
I share some reservations with the author of this post but this reads like a rambling rant more than a coherent piece of thought.

I don't want to work for companies where the toxicity permeates through the culture, and I assume that that feeling is close to how the author feels when he mentions now wanting to work for "evil" companies.

But the fact is that whole institutions aren't really evil or good - they are merely reflections of the people who are incharge of them at that moment. You can see that in any company that has gone through massive managerial changes - the company's culture & outlook has changed with them. Microsoft is the most prominent example of that.

So is Google evil or is it just that its policies as dictated by the current managerial top layer contradicts with your morality?

I guess any sufficiently large company will quickly start pushing the boundaries of ethics just by the virtue of being powerful enough to influence other people.

To avoid working at such companies you can always choose to work at the second fiddle tech shops - which provide just as much of an engineering competence (if that is what you care about primarily) without the power of influencing policies. Then you can be sufficiently happy.

Also it is hilarious to talk about putting food on the table at this day and age - yes compensation between companies can heavily vary but even a moderately competent software developer today makes more than they need just to make ends meet.
The real 10x developers in my experience are the hardest to measure. Because they pull the whole team by always being helpful and improving things where they see potential. But that doesn't necessarily show up in their results, but in the whole teams results.

Which is why metrics driven organizations in my experience with their disincentive to help others, slow everything down.
> ...that is going to be used to the advantage of Google's stakeholders...

Except the censorship things Google is doing aren't in the best interest of the stockholders. Various stakeholders (senior level execs) may be interested in censoring people, but those interests are at odds with being a politically boring company that uses its marketing muscles to sell its products.

I'm guessing that number is for all uses. Obviously, as being discussed, industrial and agricultural water uses would not be eligible.

The USGS [0] estimates 23,800 mega-gallons per day for domestic use by 268 million people. This is about 89 gallons or 336 liters per day per person.

> One of the challenges in an on chain PKI system is you need some of kind social pre-consensus on launch.

The greatest challenge, in my opinion, is that there’s a central point of failure: just compromise whichever device stores the private key for the genesis block and you get to redefine history as you please.

Compromising a Bitcoin mining pool cannot be compared to this, since it would just result in this pool’s miners losing their revenue and moving somewhere else (it can never enable rewriting the entire chain history).
Just to clarify, redhat never offered full support for btrfs, it was only a technology preview that they did not continue. So it was never "supported" in their commercial support agreement and not intended for production usage.
I think there's a big distinction because a browser is running on the user's own computer and under control of the user.

> Why should it matter with which tool the copy is made?

I don't know for sure, but I would think it matters if the tool is a third party's website (again, not on the user's computer).

To me, it seems like the difference between setting a TiVo to record a TV show for you (like using your browser or youtube-dl to access Youtube), versus asking a neighbor who has the same cable package to record the show for you and hand you a copy. Now if that neighbor is a for-profit business, that sounds more similar to the YouTube-mp3 site. And that doesn't sound like it would be legal (for the site to operate. Nothing illegal about what the user is doing).

Also, to be clear: I'm not happy that the YouTube-mp3 site is shutting down, I don't think there's anything immoral about what it does, and if I were making the rules then it would be perfectly legal. I'm just trying to understand the issues at play.

Pah that's nothing. My wife's old HP laptop had a driver dedicated to controlling the LED on the speaker mute key that used an entire core. Permanently disabling the service fixed the issue with no loss in functionality… except the LED light!
It takes the right kind of soil/moisture for good thermal contact, and it can take a very large (length and/or depth) group loop for something like an office building.

There are limits to the technology. Skyscrapers are simply too large for any reasonable number of wells to provide adequate heating and cooling, Mr. Orio said. And it would be very difficult to install a well beneath an existing structure.

Economic libertarianism is the XXI century version of Leibnitz optimism of the XVIII century, which was so eloquently critiqued by Voltaire in Candide -- with Capitalism replacing God.

Oh, sorry, that is pretty confusing. SMBH stands for "supermassive black hole." BH on its own usually refers to a stellar mass black hole. (Astronomers have lots of weird conventions.)
Yeah, it's definitely true that you want a filesystem with data and metadata checksums if you want high reliability. (I think btrfs and ZFS are the only Linux-or-other-UNIX filesystems with data checksums?)

But I think the inference to make is that Facebook trusts btrfs to increase reliability, not that Facebook trusts their distributed systems to cover for btrfs decreasing reliability to gain performance (or features).

The case in question was 10 years ago in Romania, which was only just becoming an EU member that year. I have no idea what sort of laws applied at that time in that country.

But generally, employment in most european countries is not as tenuous as you suggest. You need valid reasons to get rid of someone, and usually you need to give the employee fair warning and a reasonable opportunity to improve or correct the issue that led to the warning. Nobody gets fired for sending a single email even if it's in violation of a clear company policy.
Given the number of security vulns that boil down to broken parsing, I don't think this is true. Maybe it isn't difficult _for you_. It is still a difficult problem. By moving to structured editors, many more dimensions of data can be encoded into a program than can be cleanly represented by text.

Amazon, Apple, Facebook, Google and Microsoft are the “Ivy League” companies. They are high ROI, you will work with a selective group of peers, these peers will remain an important part of your network after you “graduate”, and putting Apple etc. on your resume will make you eminently hirable or foundable.

I know this list of companies from constant press exposure. I know this list of benefits from having gone to Apple from my (state) college, seeing the effect this has had on my career and opportunities, and comparing experiences with colleagues who went to name-brand schools.

Is there a comparable list for non-profits and social purpose and benefit organizations?

If someone wants to maximize their earnings, peer quality, technical challenge, and impact, they know where to turn. If they want to maximize their social impact instead of earnings, while still working on challenging problems with quality peers, the mainstream and technology media aren't giving them this guidance. Is there a guide for this?

IWBNI the decision process for working on positive impact projects were easier than deciding to work for profit, given that one has to take a salary hit to do the former. (And maybe it is, and I just don't know where to advise that someone look.)

New Massive Black Hole Spotted Near the Center of Milky Way
The 2008 financial crisis was sort of the beginning of -- or acceleration of -- a shift in home ownership from individuals to larger institutions who bought up distressed properties and put them on the housing market.

As this unfolds, I would be interested to see analysis of how rental property ownership breaks down in the affected area.

And to the extent it is large property and financial institutions that are impacted, my sympathy is going to be rather low.

They took advantage of the economic crisis -- one the big banks engendered -- to profit off of financially distressed mortgage holders. Now, they find themselves in a situation where they feel squeezed due to their own distress, in this case caused by a natural weather event -- and a lot of poor planning with manifold causes, of some of which they are probably complicit (holding their immediate, short-term expenses down).

As for "smaller" landlords, they have bills to pay, too -- to such large institutions. This is where "the government" steps in and sets rules -- or at least guidelines -- for how to proceed, what is and isn't permissible, and what grace periods and conditions should apply -- including terms and compensatory actions that allow the large institutions to manage, albeit perhaps with a manageable "haircut" of sorts. So that landlords are caught in the middle of a financial squeeze, themselves.

But yeah, insisting a renter cough up rent for a property they cannot use as the result of an "act of god"? Well, you have to ask yourself: Just whom should that "act" affect?
Yes, each party has their sponsors that they need to keep happy. Hence the differences.
The sponsors are... not you and I. OK, sometimes they pander to voters regarding their pet issues (transgender bathrooms, etc)

Neither party ever even tried to do anything about:

- term limits, limits on money in politics

- getting rid of lobbyists (their own sponsors)

- punishing Wall Street criminals

- reforming business law to give shareholders more control over executive compensation

- stopping the runaway train of national debt
- etc.

Both parties were/are mostly:

- anti-privacy (anti-Snowden, anti-Wikileaks, etc)

- pro-war, the military budget is untouchable, whether it is McCain or Hillary

- ever-increasing spending (despite Reps rhetoric)

- happy (Dems) or uninterested (Reps) in lowering healthcare costs

- corrupt, with "foundations" and "speaking fees" flowing freely

There is a VR library in LÖVE but not a proper lib for adventures or otjer tons of great genres :/
+1, LÖVE is my favorite prototyping framework. It's fast as blazes to develop on.

From a brief look at the github, though, it looks like a custom 3D engine with VR capabilities. Still, it's not like Love2D's API is particularly complex to imitate. That's one of its major appeals.

I was writing one of these in C++ a little while ago, and I remember being impressed at how easy it was to integrate OpenVR with my random OpenGL application. I got to a simple 'stand behind a barrier and shoot box-zombies with the controllers acting as raycast pistols before I dropped the project...

Anyways, cool stuff! I love seeing more open-source work in low-level graphics, even with existing solutions. I was frustrated by the lack of resources to learn 3D graphics math/APIs, and stuff like this can only help.

But it's true that there's nothing inherently "bad" about the code. It's just not conforming to the standard style. It seems pretty reasonable to want that to sound less menacing than "bad code", which would hint very strongly that one has something semantically incorrect.
> I must have attempted to implement a lisp many times before I got it "right"

How did you know it wasn't right? Did you run into a problem trying to implement requirements which you knew all along and accepted? (As in, you started coding without planning for some of these requirements ahead of time, then got stuck?)

Or did you learn about and adopt new requirements which weren't easy to retrofit into the existing work in progress?
Microsoft has a very elaborate backwards compatibility system. They can do things like like to some processes about what version of Windows they are running on, change the behavior of particular APIs to work around application bugs, and generally inject whatever hacks and adjustments that they need in order to ensure that old or badly written software continues to run on new versions of Windows.

It's glorious (lousy software continues to work while Microsoft is able to continue improving the OS) and terrible (software developers who are updating their software get shims applied and this complicates development, hides bugs, etc.

Yes, this. As machines get more capable, the economic role of humans diminish. This is analagous to the fate of horses after the introduction of the internal combustion engine.

Most everyone on this site has the education and skills to stay ahead of the AI revolution for some time. But many other people already have fallen behind. If the only things you know how to do can be done by machines at less cost than a living wage, then what hope do you have to compete?
By the time the industrial revolution started the Native population had already been devastated by disease. The Native Americans whose land we took were post-apocalyptic survivors--their civilizations were a shadow of what they were before the old world diseases wiped them out.

>And the civil war which was bloodier than all the other wars we participated in combined.

Only because the causalities from both sides count as American casualties, and because we developed better medical treatment and sanitation technology.

Far more civil war soldiers died of disease than combat, which was mitigated in later wars through advanced technology. The number of US combat deaths was higher in WWII.
