copy-on-write took so long to set up that it was frequently cheaper to just do the copy.

Right. QNX just copied for interprocess communication. Mach did lots of messing with the MMU to create temporary shared pages. That seemed to be a lose.

* What you want for interprocess communication in a microkernel is something that works like a function call - send data, wait for reply. If you have to build that out of unidirectional messages, it means more trips through the CPU dispatcher, and probably going to the end of the line waiting for a turn at the CPU. Call-like approach: Process A calls process B, control transfers immediately from A to B, B returns to A, control transfers immediately to process A. No need to look for the next task to run; who runs next is a no-brainer. Pipe-like approach: A sends to B, both are active for a moment, A soon blocks on a lock, B wakes up and does its thing, B sends to A, both are active for a moment, B soon blocks on a lock. A and B fight for the CPU.

The "going to the end of the line" effect is that when other tasks want the CPU, the pipe-like approach means other tasks get a chance to run during the handoff. The effect is that message passing performance falls off a cliff when you're CPU-bound. QNX used a call like approach (MsgSend/MsgReceive), while Mach used something more like pipe I/O.

* Mach started from the BSD code base. Trying to build a microkernel by hacking on a macrokernel didn't end well. Microkernels are all about getting the key primitives at the bottom working very fast and reliably. There was an eventual rewrite, but I gather that BSD code remained.
Yeah seems rather risky to be operating literally in the backyard of a major German submarine base. Six Type 212 subs are based in Eckernförde, one is actually on the marine tracker linked in the comments above [0] right now. If a submarine pops up there unannounced that's a diplomatic incident at least and with a naval base nearby the risk of discovery would be rather high.

> If you have one persona, that means that you need to optimize that persona for your career and ironically it feels more stiflingly conformist.

I understand where you're coming from, but this statement isn't necessarily a truism. You can wear who you are on your sleeve and even be quite extreme, if you're a reasonable person who can build and maintain professional relationships.

I do almost everything online under my real name, and am not optimized for career purposes. It's just me. As a result, I've had my political beliefs and such come up in interviews on multiple occasions. In one case - as I found out a year or so after being laid off - my interview process took a couple of weeks longer than was typical because one of the executives/partners at the company was concerned specifically about my politics. On the other hand, I did in fact get that job (and loved it!) and I've gotten several connections and invitations to apply based upon my discussions. Surprisingly, they seem to be about evenly split between people who agree and who disagree with my stances. I'm passionate about political issues, but I do my best to be accommodating to others and not be aggressive about them.

It would be fair to say that my positions are pretty extreme, too. I'm a political anarchist; Anarcho-Capitalist / Voluntaryist, to be more precise. I am open about that even in professional settings because it has such an influence on how I approach relationships and the world in general. I tend to be a "systems thinker", and see everything as a balance of competing forces. I see the whole world through this lens; everything is influenced by incentives and disincentives. I have exactly one tattoo, a stylized graph of supply and demand.
I disagree. The violent actions of others don't make your action of exercising the right to protect yourself inherently violent.
Currently both Amazon and FedEx both use independent contractors (sorry, entrepreneurs) - and your experience will vary widely with the contractors operating in your area. We always groan when FedEx is doing the delivery, because in our area that usually means two or three days of 'missed deliveries'.
All distributed databases (and, frankly, all software) have bugs. At leat with Yugabyte you have some idea of what the bugs are because they tested them and published the results.
The Federal Reserve only steps in when there is 1) system wide risk, and 2) when the company they are interfering with owns enough assets to guarantee the fed loans.

* Bear Sterns had healthy assets, Lehman Brothers did not.
AIG had enough healthy insurance premiums to guarantee the loan to fix the unhealthy insurance products.
Fannie Mae and Freddie Mac owned the home mortgages assets.

1) WeWork doesn't have a substantial enough real estate position to bring down the entire real estate system.

2) WeWork doesn't have any assets to guarantee a fed loan.

I was frustrated at work about whether our "Agile" practices were really agile, and then the Rick Sanchez voice in my head spoke up: "Look, Morty, nobburpody gives a shit how 'agile' you are, or whether 'stories' actually meet the qualification for user stories, or whatever other horseshit you can think of. No one gives a shit about quality, either. All that really matters is that you make the ink on the bottom line black and make your boss look good. You could literally be shoveling out buggy shit with waterfall and no one will complain as long as you meet those criteria. Don't like it? Tough titty, motherfucker! Welcome to wage slavery! Now swallow your food pellet and get back to work, those giant capstans aren't going to turn themselves."

We bid on a basket of groceries by choosing a store to shop at though. The price of oranges is mostly immaterial when compared to the greater pricing of the collection of goods purchased in a single trip. This is why loss leaders make sense. They entice you in w/ a distorted price and then recoup the loss across your basket.

> When an index fund investor sells, they’re technically selling their holdings in direct proportion to their weighting in the index. So there is literally no market impact.

Correct me if I’m wrong but isn’t there a well known price premium for stocks included in major index funds? As I understand it, the most popular indexes target a few companies, thus index funds that track them funnel a disproportionate volume of demand to those companies causing a price premium.

It’s stands to reason that if a sudden outflow of money from index funds occurred, that price premium would swing the equal and opposite direction.
Not all dating is about long term relationships. There is a large spectrum between, say, AdultFriendFinder on the one and Parship on the other end. Not sure where Facebook think they are going to be in that spectrum.

Ideally, processes should be the same worldwide except for differences required by local laws.

IIRC, it's all independent contractors. Whether it's an independent company contracted by Amazon (which is the bulk of it), or a direct Lyft/Uber-style gig economy model of sourcing contract drivers.

Here's a (somewhat sensationalized, it's Buzzfeed News) article about some of the negatives that have shown up. It references that all of the delivery network is decentralized:

I don't think "the contractor did it" will get very far, either in court or as PR?

Though, there is legal indemnification which could be used to get a contractor (the company) to pay when there is a screwup. But that's a matter of contract negotiations between companies.
The same can be said for end-to-end encryption...
I'm still not convinced, but I guess I'm lacking critical technical background to grasp it.

1) The CEO example isn't really a good one to me, given the wealth inequalities in the world, leaking CEO's salary is almost desirable... I tried to read the blogpost and paper about mobile data location. At one point they talk about aggregated data, but then in the paper : "This dataset
is collected by a major mobile network operator in China.
It is a large-scale dataset including 100,000 mobile users
with the duration of one week, between April 1st and 7th,
2016. It records the spatiotemporal information of mobile
subscribers when they access cellular network (i.e., making
phone calls, sending texts, or consuming data plan). It also
contains anonymous user identification, accessed base sta-
tions and timestamp of each access.". So... the data is not really "aggregated"? The dataset literally lists some user IDs.

2) If I'm fired because my boss didn't like my history of movie, then it can probably be defended in court, depending on the country. I could also find another boss who has a natural sense of ethic and who doesn't judge me for what I watch.

Very interesting. Will surely read it and reach out if questions arise. Thanks!
Right, but in industries that are not replaced (like mail), you're forgetting about the effect increased efficiency will have on demand. A counterexample would be when looms increased employment in textiles. Less people were needed per item, but it was so much cheaper to make textiles that the increased demand ended up employing more people in textile mills than ever.
Unfortunately it looks like they picked Aspen, the wood, rather than Aspen, the ski resort. (Also, wasn't iPhone OS 1.0 code-named Alpine?)
Worth noting, even if you have an extended exercise window (i.e 10 years), your ISOs will turn into NSOs after 90 days since your departure (and thus have a different tax treatment!).
Great work - this looks very cool. We'd be very interested in exploring it. We started looking into https://www.appcues.com/ but their pricing seems prohibitively expensive. They have a nice Chrome extension that allows nontechnical folks to easily create/customize the onboarding/tooltips for your app -- curious how your snippet will guide users through creation.

Myers-Briggs is, to me, much more helpful for understanding my reaction to stimuli, but doesn't provide as much use for me to engage with other people. The enneagram, arguably less scientific, helps me understand my tendencies when interacting with other people. I'm an ENTP type 8, which essentially translates to an extroverted intuitive person with very low agreeableness. It helps to police my own interactions, since I can't exactly apply the golden rule.
Luck. Invested in Alibaba and Yahoo JP (and he funnelled money into the latter pre-2001 from other projects to boost revenue). Got money from banks that didn't close him out when they should have (this would have happened anywhere in the world bar Japan and, possibly, Germany).

Son's record as a VC is horrible. He raised something like 6 VC funds before 2001. None produced anything but busts. And he actually invested more capital on the way down.

His only quality is zealotry. This the absolute worst possible trait for an investor (he isn't an investor, he is a salesman).
Completely agree. Multiple times I've had USPS drivers report packages as "delivered" late in the day when they were not delivered at all, then they are actually delivered the next day. Sure makes their metrics look better, though.
> the other part wouldn't trust the math and the implementation behind it.

I trust the math and method just fine, but I'm in the "won't trust the implementation" group. Ad companies like Google have demonstrated they can't be trusted too many times for me to think that they'll do DP in a way that goes against their business interest.
>The government has problems but trends towards the people's benefit in the long run. Corporate greed trends towards enriching the lives of sick and disturbing rich men like Larry and Sergey.

>Corporations are a far worse and far less regulated threat than government, with far less checks and balances in place to protect us.

Tell that to the victims of US foreign policy. 1+ million Iraqis dead, ethnic cleansing civil war, and the unleashing of a theocratic cult recently is just the tip of the iceberg. Do I really need to add up all the dead in South America, in South East Asia, and around the world from your "mostly benign, government has problems but trends towards benefit" scenario? Maybe YOUR benefit, but you've been privileged to export misery and suffering to other people around the world.

I tell you what, go visit the war museum in Hanoi, and gaze at the deformed children who are still affected today by Agent Orange, or those still being blow up by land mines and other unexploded ordinance.

This is the sad navel gazing of the privileged and comfortable, hyperbolizing theoretical threats and getting triggered over minutiae, and hand waving away the utter misery and very real dangers that have been shown over and over this century. This is not to assert "whataboutism" and claim that privacy isn't important, it is.

But trying to argue that ad targeting is the greater threat than US (government), when our foreign policy's stacks of bodies piled miles high strikes me as naive.
IMO the real issue is amount of cash available for investment and the lack of investable assets[1].

If i were king for a day I'd legislate a low bar that required the equities to be listed so that both the insiders cannot be barred from liquidity and so that the investing public can access those parts of the economy.

I am in this boat. However, I've been waiting for this phone for so long, that I've regressed to a flip phone since my previous phone broke and I was unwilling to buy another smart phone since the Librem was coming out in only a few months. So I appreciate the published schedule, it allows me to weigh the pros and cons of getting the phone earlier vs having the benefit of getting some of the kinks worked out. It seems that the hardware won't change much except for mechanicals, so at this point I'm thinking I'll wait for the second iteration just because there's always something with the first one :)

> But the theory posits internal mechanisms, and nobody has determined a reliable to measure this yet

That's the generalized problem with psychoanalysis. It rings true, but lies outside Popperian lines. It's not science in the contemporary sense.

Then again, psychology within Popperian lines isn't doing so great. My hot take is that modern psychology's problem is not about overemphasizing biology or anything like that -- it's that it tries to be "enhanced behaviorism": start from what's most superficial and apparent and try to find e.g. what's the molecule of love or the rational (cognitive therapy) way of dealing with depression. Physics got where it is by postulating general principles (e.g. conservation of energy) from shreds of evidence.

To do this with psychology takes you outside Popperian lines.

Or hell, even start a personal blog using your real name talking about opinions that are anathema to coastal dwellers. Watch your callback rate dramatically decline.

I grew up in a suburb of a conservative state, and I learned early on when to show "who I am and what I really believe" and when to be low-key about it. Others like me who did not learn that skill were bullied relentlessly. I got along pretty well.

If you actually had opinions many people disagreed with strongly, you'd be bullied and held back as well.

Or maybe these two links would be of more interest, actually being the EU legislation in question (the later modifies the former):

https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CEL...

https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CEL...

As I understand it, the former is implementing some international agreement where EU member states chose to use the EU as the mechanism to implement the agreement. The later seems to be the EU gold plating that (e.g. limiting anonymous electronic payments to €50).
> If we find nothing there, this gives us a profound result: no one has come to look at the life of Earth

Not quite. A probe can self destruct (like we did with Galileo and Cassini) or never even enter solar orbit. If I send a dozen probes in a single package and they disperse slowly from each other along the axis of travel, they'll pass Earth at long intervals. Using the available energy to send a message instead of slowing down and entering orbit would allow for a much stronger signal, with a lot more information packed in it.

Ask HN: Web developers – how did you get good at designing things?
I'm a web dev with a decade of experience with all things frontend, but I mostly consider myself a JavaScript engineer more than anything else.

I've found that for most things, I can usually work out how to get good/decent at something by reading/writing code/watching talks/talking to peers etc... However, the one thing that I still remain utterly garbage at is design. I can implement layouts and implement designs when given them from a designer, but for the life of me I cannot come up with anything that looks pretty from scratch. I want to get better at this but can't work out how to improve.

Can anyone with a similar background (or any background, really) share their story+tips?
Speculators may do no harm as bubbles on a steady stream of enterprise.

The trouble w/ USB is that it wants to serve everybody.

At the very beginning there was a low speed for mice and keyboards and then a high speed for more demanding devices. That way input devices could be cheap but still plugged into the same port as other devices.

At that time there was FireWire as a competitor, also external SCSI, etc.

For a long time USB has been the low-end mass-market serial connector but now that USB is converging with Thunderbolt, you're left with awful compromises to support both low cost and high performance on the same port.

>isn’t there a well known price premium for stocks included in major index funds?

Maybe the premium is for being in the index, which the index fund dutifully reacts to. There are only 100 places in the FTSE100 so it is seen as significant. The current news about a major UK high street retailer is that it dropped out of this index, implying it's the beginning of its end. https://www.google.com/search?q=marks+and+spencers&tbm=nws
When sick, you continue going to work until you wind up in the ER. If you're lucky, you don't get fired when you're there. Only exaggerating slightly. It's pretty sad.

As for what happened, the US isn't highly unionized outside certain regions and trades. Everybody else has next to zero legal protection. White collar workers typically get some leave simply by virtue of having skills that are more in-demand. And the labor movement largely allowed conservative, anti-labor factions to cast them as evil socialists. In the US, "liberal" has long been a bad word.
And also no one with strong conservative beliefs can really survive or rise to prominence there.
