This question isn't directly associated with MongoDB, please forgive my lack of OSS license expertise.

I was curious if exceptions were allowed under licenses like these. For example, if a company releases a GPL licensed product, (or SSPL etc) and wishes to create another product/service that they don't wish to open source, but it's based on the GPL/SSPL codebase. Could they make exceptions or separate license agreements to go around their own license choice? Would it be different if it were a third party they would like to give this exception to?

In similar regard, would MongoDB have to prove that they are paying full licenses/Enterprise agreements to themselves to be able to run Atlas (their own cloud offering) and not open source Atlas? Or is there a self exclusion allowed etc? Or would they just sell themselves the licenses for $0.01 cent to get around the requirement?

Truly interested in this question.

Edit - and to clarify, not if the exception is stated directly in the license like a new modified MIT etc, but inherent to the existing popular OSS licenses.

Yes, with App Engine, you upload source code, and it's compiled for you remotely. For this newer runtime, it happens inside a Cloud Build invocation.

For App Engine flexible, you can skip that build step and provide your own container, but that isn't possible for App Engine standard. (If you're interested in something like that, see https://g.co/serverlesscontainers)
When interest rates rise, bond prices fall.

So when you see interest rates rising, that means there is more selling pressure than buying pressure.

Just like anything else, it is harder to sell bonds and get the price you want when bond prices are falling (and interest rates rising).

It's easier to sell and get a good price when bond prices are rising (and interest rates are falling).
"Exponentially" isn't all that bad; what people actually mean when they say it is usually "superlinearly", but there's no practical difference between the two when talking about e.g. scaling problems.

160k is actually on the high end for PSD work now, with the contractor total staff numbers in Iraq/Afghanistan down to maybe 5-10% of what they were during the peak around 2007-2009. There are A LOT of guys out there who have 1, 2 or 3 years of experience doing something PSD related during the peak contractor-staff periods of the Iraq and Afghanistan wars, who are back in the US doing very normal things right now.

The salaries they're paying for US Citizen guards at the US Embassy in Kabul are around $90k at present. There's a sufficient number of people who really need the money that they can recruit and fill positions at that figure.
Dumping money in people's bank accounts would be a process called helicopter money, named after the suggestion that central banks could stimulate the economy by printing new money and scattering it out of helicopters. Sadly the Fed hasn't tried that yet.

What central banks are doing is buying bonds and other assets from the private sector, and paying for them by creating new money. In the past they might have created new money by ordering a truckload of new $100 bills to be printed, but now they can do it simply by changing the central bank balance of whoever they are buying the bonds from.
And fewer and fewer people benefit from it.

So okay. Great. Now let's do it in a way that doesn't turn the entire nation into a series of hyper-reactionary tribes fighting over leftovers.
> The next time Democrats are in control you'll be sure to see GOP complaints that the defecit is a problem and entitlements should be on the chopping block.

They are actually doing that right now, even though they created the massive deficit increase.

That's because to them, entitlements are the problem, and the deficit is just the standard excuse.

The real question would be "inflation adjusted per-capita tax receipts over time" but a mid-work googling didn't turn up anything promising; that being said from the above graph _and_ the knowledge that inflation is increasing, your statement doesn't seem to mesh.

I could have worded that more clearly. In Australia's case, rules regarding foreign property ownership/investment have historically had a fairly big impact on housing demand, pricing etc. The government of the day is regularly lobbied by those who have a vested interest in seeing prices continually rise to relax those rules. I'll leave it at that.

People who write "x is O(n)" usually actually mean to write "x ∝ n", but 1. ∝ is hard to type on a keyboard, and 2. even fewer people (including CS majors!) know what ∝ means, than know what O(n) means well-enough to allow them to figure out its non-jargon usage from context.
It's unfortunate that more people don't internalize this fact. One of the first things you learn in middle/high school ecology is that 90% of available energy is lost between each step in the food chain. Producers can only convert about 10% of the sun's energy to useful electrons in photosynthesis, herbivores only get 10% of the energy it takes to grow their food, and carnivores only get 10% of the energy herbivores take in. Some factors like the decreased non-predatory death improve those numbers for industrial agriculture but not by much.

In US agriculture, we have some estimates for the ratio of output calories to the input calories [1] that are astounding. For every 100 kcal of feed stock, we get ~19 kcal back from chicken, ~7 kcal from beef, and a whopping 1 kcal from shrimp.

Essentially, every 1000 kcal of beef takes 14,000 kcal of corn/soy/alfa-alfa and 1000 kcal of shrimp takes 100,000 kcal of whatever it is shrimp eat.

Which is even scarier.

In case of default, discretionary items can be seize and sold to at least repay part of the debt (while decreasing quality of life).

2008 has shown what seizing houses leads to.

Now think that there is nothing to seize for student debt loans.

If you fail to get a good enough income using the degree you paid using debt, you are as hopeless as if you had used it all on hookers and cocaine. At least with discretionary items you have a big TV which holds some value.
Bitcoins don’t work for that. If you want to buy bitcoins with Currency X you need to find somone that wants to sell bitcoins for Currency X. Similarly if you want to sell bitcoins for Currency Y you need somone to buy them in Currency Y. Net result you can’t get large net cash flows unless people can exchange currency X for Currency Y.

PS: Bitcoin mining is another story, but it’s little different than building anything in China and selling abroad.
Ask HN: Issue bounties for GitHub projects?
One of the largest motivations for users to donate to open-source projects is for their funds to be used directly for features that benefit them. Is there a service that allows users to "pledge" an amount of money for particular GitHub issues that are cashed out upon marking them solved?
What a beautiful tribute!
The missing piece of logic is that the Republicans don't actually want to fund their expenditures. Democrats may be the party of tax and spend, but Republicans are the party of just spend. The former provides back pressure to the electorate, the latter is a recipe for ruining the country regardless of your policy preferences.

For a long time I couldn't wrap my head around why defecits matter to the US when we print our currency. To be honest I still don't fully understand the hand wringing over a balanced budget and reading more about modern monetary theory is leading me to believe that for a superpower which issues it's own currency the defecit is more of a political issue that a concrete one.

The defecit just keeps ballooning but the only thing stopping the US government from running are self imposed restrictions on debt (the "debt ceiling"). The US is not a company, and it's not a normal household, why does the budget matter?
Nobody gives a fuck about your landing page with two sentences and an email capture box any more. The world has moved on from this model.

Good thing the lean startup was never about this.

The lean startup movement actually grew out of the work by Steve Blank, best summarized in the (unfortunately titled) book 4 Steps to the Epiphany. Eric Ries basically made it more accessible and catchier-sounding, but a LOT of the ideas from that movement are things we take for granted today in the startup world. They didn’t stop working, they just became the default instead of a new way of doing things.

The whole smoke test thing where you setup a shitty landing page and collect emails as validation is more from Tim Ferriss and The 4 Hour Work Week.

Oh, and for the record, it still works. Look at presales, Kickstarter, etc. Same idea: demand validation.

Finally, I reject your idea that everything that people want and need has been built and we’re all just bored and fatigued. Doesn’t match my experience as a business owner, consultant, or consumer. There’s more opportunity for innovation than ever before.
https://www.strava.com/segments/622627 is the hill I'm talking about. Agreed that they are likely putting in much more power than I can at that heart rate.

My naive understanding is that I can push more time in higher heart rates and slowly pull up what I can do in the lower ones. That said, I'm just aiming to be consistently in the 6 minute time frame for that hill by next year. As things are, I'm quite winded if I hit the low 7 minute time frame. So, trying to pay attention to any methods I could use to make that better.

The Fed doesn't just dictate interest rates, because who would listen to them? Instead, interest rates are set by the market.

If the Fed wants higher interest rates, they sell bonds in the market. If they want lower interest rates, they buy bonds in the market.

So if China sold a ton of US debt, that would reduce bond prices and increase interest rates. If the Fed wanted lower interest rates, it would need to buy a lot of that additional supply that China dumped on the market.
If I own a block of code, I can release it under as many licenses as I like, even if those licenses would totally conflict, and then each one of my users will need to track which license they received it under and adhere to those terms (only). So yes, I can give Users 1, 4, and 5 a copy under the GPL, and then users 2 and 3 a copy under some commercial license, user 6 under some GPL incompatible copyleft license, no problem.

The key is where you say "wishes to create another product/service that they don't wish to open source, but it's based on the GPL/SSPL codebase". You're not creating it based on the GPL codebase, you're creating it on the codebase you own. The fact you've previously licensed it under X, Y or Z licenses is irrelevant; you can always release it again, in whole or in part, with whatever license you like. (But of course, whatever you released under the GPL is still out there, under the GPL; there's no take backs!) And you can also, of course, use it yourself however you like.

The key is ownership. If you own the copyright on the code, you're fine. If you don't, you must adhere strictly to the license which the actual owners granted you. To the extent that MongoDB (the company) owns the copyright on all the code, they're free to use it how they like, and release it as often as they like under whatever licenses they like.

FFTW certainly isn't simply written on OCaml. Apart from higher-level C, at base it has the sort of low-level micro-architecture-specific kernels you'd expect (using C intrinsics rather than assembler in this case).

The term "open source" has been generically used for much longer than OSI's existence.

I've seen this claim before, but could never find any evidence of it actually being applied to software before OSI came around.
The whole "cybernetics" field is pretty weird to me, I think the notation and lingo have sort of moved on (I could easily be wrong and biased without realizing).

However the theorems you are talking about have useful, well studied analogs in the field of control theory.

For example the Law of Requisite Variety is very much related to the concept of under-actuation (https://en.wikipedia.org/wiki/Underactuation).

The good regulator theorem becomes the internal model principle. https://en.wikipedia.org/wiki/Internal_model_(motor_control)

I think you'll have much better luck finding good introductions to these topics in control theory than in trying to learn more about cybernetics.

There are now 5 million visitors a year. So it's not really shocking that more "mainstream" stuff does better these days than it might have done back in the day.

I sometimes get accused of posting political pieces when, to my mind, they are interesting for sociological reasons. I certainly don't post things to promote any kind of political agenda per se.

I also didn't notice the things you are specifically commenting on. I recall different details from the front page. So there's possibly a certain amount of "You just happened to see X for some reason." which isn't conclusive proof of objective fact.

BitWarden has come a long way and now it does everything I need: iOs integration (in ios12), Android, extensions for all browsers, and even the (fairly pointless but customary in 2018) electron-based desktop app. It’s even opensource, so one could host a private instance - which I’d be keen to do if it weren’t based on the annoying Microsoft stack.

The only feature I miss is the little gamification that LastPass has, where you can check how many of your credentials had the same details - lowering that score day by day was a nice challenge. I was tempted to build it myself (BW has an API too) but not got around it yet.
Redistricting as an NP-Hard Problem
You can allow the general public to use your code under the SSPL, give somebody else the same code under the GPL, give a proprietary licence to somebody else who paid you money, and use it yourself in a way that would violate any of those licences. Licences you give out can't really restrict you, since you own the copyright of the code.

The piece in the puzzle that allows MongoDB Inc. to act like that is the Contributor Agreement [1] which makes any contributor assign copyright of contributions to MongoDB Inc. This way MongoDB Inc. is has all rights on the source code and can licence it to anyone under any licence.

I'm not quite sure how to parse that particular piece of data. It seems as though it may be nominal if we consider that the Household Debt-to GDP ratio is substantially decreased from 2008. Further, household debt service ratios have also decreased substantially (by roughly 30%).

Frequently when writing O(n), the writer is making a comparison. e.g. "The GC was O(n log n) wrt memory, but now it's just O(log n)." That expands to a lot more text.

Or, to put that another way: there is a constant cost in human parsing complexity when writing "O(n)", but the number of parse-nodes in the text when using "O(n)" only increases as O(n), whereas without "O(n)", it increases with O(n^1.3). ;)

Fair enough, it was just an example... maybe a bad example of when public trust is needed for something.

But, that level of trust and audibility would be nice in this era of conspiracies and fake news. I remember watching CNN on 9/11 and they reported that Flight 93 was shot down over Pensylvania. Maybe that was bad reporting, maybe it was accurate. But, now I can't find that footage anywhere.

I would love to find that footage now. Find out exactly what they said. Find out who their source was. Find out if it was bad reporting with bad sources, or find out if it was something more. Without that footage, it's just hearse and I'm sure we'll never know the truth about it now.

'No military anywhere' seems to be a trivially unstable equilibrium. If nobody has any military and some group of people decide to create one and use force to dominate their neighbors, how exactly does anyone stop them?

Even if 99.99% of the world would prefer to not have any military and keep it that way, all it takes is a tiny minority of defectors from the norm.

Right, so how do you resolve disagreements when people want different things? Should we have a world democracy, where China and India get about half the total vote?
