I asked this question below and apparently it warranted massive downvotes:

Is there any data on how many of the angels and VC's have a background engineering, math, sciences vs. law, business and others?

It seems to be that correlation requires more than just, he's a guy, he get's more. She's a women she gets sexually harassed, she get's less. In one of the US offices I worked in I kept getting a lot of shit from some colleagues and a middle manage who's wife was one of the first employees and highly influentual. A year after I left, an ex colleague tells me that a good friend of that lady, also a lady, that didn't like me told everyone I talked shit about her breasts. Germany, half a year in, turns out the girls in the company are talking about my cute ass.

Is the difference that they did it behind my back, besides proactively? Can power dynamics really be boiled down to a plain men vs. women? Nothing about demographics, social context, history etc.?

Are we saying that Elizabeth Holmes is treated the same as some no name immigrant female founder? Or a random no name immigrant male founder even?

> MySQL connections use less memory [...] handled as a thread

I've not measured recently, but from the angle of a PG dev I'd be very surprised if that weren't true.

Note that one unfortunatelycannot just compare the memory usage of a individual postgres connection processes with a threaded connection model. Read-only things are mapped multiple times, and a lot of the read-write memory is copy-on-write and never modified after startup. And a good chunk of the required memory is in shared memory and thus not duplicated.

I strongly suggest using huge pages (huge_pages=on, and configure the os to allocate them) if memory usage due to connection count is a problem when using PG. The page table is usually one of the biggest users of per-process memory.

With the popularity of non-real-name Instagram pages and "finstagrams" it seems strange that Facebook has not implemented a checkbox for "seriously, this is not my main account, please stop linking it to my main account or phone number or facebook account or suggesting it to ANYONE I might know in real life". But, then again, it is Facebook we're talking about.
Fantastic! Thanks for the suggestion.
All things are like this. Hyper-growth hides excess and screwups. Then you retrench and clean up.
How does go select over N channels where N is not known at compile time these days? I remember the helper API as clumsy and unintuitive. I am sure this has changed since I last used go. Back then (about 2014?) I found go's concurrency model lacking, or at least a little bit too opinionated when compared to CML. Sure, it was possible to work around the limitation, and the extra performance you got from utilising all cores was worth it (parallel CML is a rather new thing, but is getting more common.).
Which models did you look at? I don't remember a lot of models that are new to the market recently. I checked the Mazda CX-3 and the Nissan Leaf, and the Model 3 does appear to have crushed both of those based on first year numbers.
Creative writing, maybe? Outside of founder-level product managers, of which I have worked with several who are actually creative, I remain unconvinced there is much real difference.

Just because something is bad, doesn't mean it is a problem. Murder is bad, but isn't a problem in most US cities since it doesn't happen that often. I don't think swatting happens enough to be considered a serious problem we need to worry about.
>It's a tricky problem to really make sense of though just because investors are so diverse.

Are they? I think it could be argued that investors are one of the least diverse groups.

Analysis of 1,500 investors:

==70% are white

==40% of venture investors have attended Stanford or Harvard

==One percent of venture capitalists are Latinx and only three percent are black.

If our concern is with results, then we should be looking for the best predictor of results, and school type may well improve our predictions, as you say.

We should aim to admit to medical school the people who'll make the best doctors at age 40, not just the people with the best scores at age 18.
Where does FB say it sells your data? Was there a news article about it?

I see this repeated about other tech companies as well but I can never find where they say they sell my data. It seems weird companies would sell their most valuable asset, rendering themselves moot.

My understanding is these companies allow advertisers to target users, but never sell the data.
There's nothing wrong, at least conceptually, with Herbalife's products, protein shakes.

However, Herbalife's success comes from their incredibly shady and destructive pyramid scheme that preys on individuals and tricks them into acquiring debt in exchange for becoming "distributors" of Herbalife products. According to the FTC [1], "it's virtually impossible to make money selling Herbalife products".

I recommend the documentary Betting on Zero [2] for more insight into Herbalife, as well as the fascinating story of Bill Ackman's failed attempt at shorting their stock at a huge scale.

I know several people who were born abroad and raised abroad but are US citizens because their parents are citizens. Every year they have to report every cent that they own. In foreign bank accounts, foreign retirement funds and foreign investments. They have to file taxes every year, which means paying several hundred dollars for a tax attorney. They are unable to open several local bank accounts and several of them won't even hire US citizens for any possible job at the bank.

If renouncing citizenship was free then they would do it in a heartbeat, but alas the US wants to steal even more money from them.
TheArtOfHttpScripting – a tutorial into HTTP scripting with curl
I really like your thinking here, especially the "more like real world" part. As you outlined in the previous comment, the source of the problem is the increased communication rates - in the offline world, you normally have like 60 microassholes per second, while online you can easily get up to 30K microassholes/s.

This change of communications with assholes rate brings asymmetry that is a cause of the problem: you still have the same response capacity and emotional response decay time as in the offline world, but the incoming rate of assholes is so huge, so you can't cope with it anymore.

So perhaps any solution should be seen from this perspective: decreasing the upper boundary rate to some reasonably acceptable value.

But it also may lead to the opposite conclusion – we now in an online world, with different speeds and rates of everything. Maybe solutions "like in the real world" simply won't work anymore here. Perhaps we can use some new tools to solve these sorts of problems, that we never had in the offline world?

For example, there was a brilliant idea to set a price tag for your attention in the online world. Imagine an email system where the sender should pay some price for you to receive it and read. This price can be dynamic and vary according to various parameters – from sender's identity to my current mood. If someone sends me a public speaking request or is trying to hire me, they'll pay like 5$ per mail, but for my friends or coworkers asking for help it could be 0.03$. And if my inbox is empty (ha-ha) and I'm in the mood to explore who's writing me, I can temporarily lower the price for all. That's of course, just a rough sketch of the idea, but it might work in the future if cryptocurrencies become ubiquitous for example.
>Google admitted that they don't keep any logs around.

They didn't say that, they stated that in the logs they had, which were not fully comprehensive, there was no evidence of abuse.

> am not sure how they are making the claim that their API was not abused.

They didn't claim this.

But one could, for example, set up a honeypot and monitor any suspicious activity going forward, then if anyone attempted to abuse the vulnerability before it was publicized, they would know it might have been abused, but lack of use over a long timescale could give reasonable certainty that no one took advantage of the vuln.

(I work at Google, but not on G+ and not on security).

Yea, typically we don't owe. Many of us live in "socialist" countries with higher taxes so we get credited for that.

You're right! There are laws in some places requiring notification in the event of a breach. California has one of these, and some provisions of GDPR are similar.

With that said, I don't think any of these require notification in the event of the abstract possibility, unsupported by any evidence, of a data breach. This is because there is a substantial difference between data that was emitted (factually sent somewhere) and exposed (could have been sent somewhere), and laws tend to trigger on the former.

If you're aware of relevant laws I have missed, I would love to know!
> fashionable belief in the West that democracy cannot work because people are idiots whose vote can be turned by a meme on Facebook.

> One Chinese participant had heard from a friend that, for the same product, Taobao charged iPhone users more than it charged Android users.

Interesting. I recall reading that some online flight booking site did this for Mac users a few years ago, along with raising prices if you search for flights and then come back a few days later. I always make a point to use a VPN and spoof my browser ID when I book travel just in case.

ETA: Ah, as I continue to read I see the article references this as well. No idea if it's true, but I'll continue my behavior. I suspect that people do see prices change, but that those changes are based on other variables.
Interesting. So, for instance, you are aware that women did not have the fight to vote until 1920.

Is your belief that women have never been marginalized? Or that they used to be, but in quantitative terms this group by now in 2018 has attained an equal amount of power?

Does anyone have an understanding of if and how much this applies to AWS's Aurora service, when operating as a PostgreSQL database?
Yeah, I'd imagine a new Rav4 or CR-V model goes from 0 to 10,000 a week pretty damn fast and with little to no fanfare.
Obviously I have no insight into your implementation, but I"m not sure why you would "have to" declare the field on your model. There are probably a lot of different ways handle this situation. For instance, you probably don't have to use the ActionView helpers. There's nothing preventing your controller and view from just passing non-model parameters back and forth.

Rails has never made the promise of giving you every a solution for every situation in the wild right out of the box, and I don't understand why people seem to think it does. No framework could ever do that. What it does is abstract away the common stuff that makes up probably 95% of most web apps, and gives you the ability to roll the rest on your own.
It's odd how right after that era the design stuff we're getting nostalgic about was derided more often than not. Is that something you remember as well? It's not that it was pointed out as being terrible and nasty like, let's say Geocities or MySpace type pages, but I know there was a drastic shift and unlike most trends it hasn't seemed to loop back on the internet of all places where things seem to cycle back into popularity faster than something like fashion? Maybe that's my personal perception but it feels at least somewhat correct.

> it was sort of a thin veneer atop good old raw plain fast HTML

Yes, I loved that too! It felt like you actually had a handle on everything your website was doing and was comprised of. There wasn't anything involve with it that you just installed and assumed would work. Each decision and technology was something you knew inside and out and employed specifically.

Things these days are crazy, eh? Maybe it's a bigger combination of that part of it plus the fact that it looked the way that I described that creates the fuzzy feelings? Well, if I ever get around to doing what I said above I'll have some sort of answer, haha.
Ask HN: What are good resources for aspiring technology leaders?
Dear HNers,

Do you know of any worthwhile MOOCs on tech leadership? Books are also good.

Why: I am SE looking for change in following years. Some experiences taught me there is a shortage of true leaders in the field (Peter's principle). I am looking for resources that include but are not limited to:

* conflict resolution

* managing up

* office politics

* understanding project dynamics (e.g. R&D projects vs apps for well-defined business processes)

* development processes (I don't believe that Scrum is all we have)

* product development

* innovations management
I learned 20+ years ago and I feel like back then it was a lot easier to learn. You would get a VB or C++ book and immerse yourself in it. The book would be self-contained --it had all the information you needed to become decent at that topic. Once you were done, you moved to the next book.

If I was learning today, I think that I would be completely overwhelmed by the amount of information that we have at our disposal. It would be harder to dive into one thing while being bombarded by the other 300 things you are supposed to learn because everyone is talking about them.

When I mentor young programmers, I advise them to focus on a single language/framework for a really long time, until they achieve real proficiency, and actively filter out everything else.
It’s a serious concern. I bought an special anniversary edition of a car, had something hit me on the highway a month after, and had to wait a month for the manufacturer to make the special parts.
I was coming out of the subway with my GF and some guy came up to her and threatened a pretty violent act. I said "What did you just say?" and the guy, realizing she was with someone, turned a bolted.

I was angry but my GF just shrugged and said, "this happens all the time in Yorkville".

I'm really getting tired of people continually bashing Kevin Kelly. Kelly's book, New rules for the new economy, was what gave me the final push to quit my job and become a software entrepreneur. But he got few things wrong in that book and the criticism was so harsh he stopped writing books for a few years.

Kelly is a cheerleader. But he ties disparate threads together and gives you a mental model where he sees the future going. He's been far more right than wrong. But some people I guess are natural born pessimists.

George Gilder has a similar approach. Kelly wrote in Wired in a famous essay after the 2000 crash that the Internet was at the beginning of a 200 year boom and I believe that to be true.
This makes me super happy. I bought the book a few years back and always meant to go through it with rigor to build my own renderer. Now I have that free time but as a digital nomad, I couldn't bring the book. (its up there in size).
>US government backs it

Yes, by putting people in jail who put forward viable alternatives to USD, like Liberty Dollar. And making Bitcoin impossible to use legally as a currency by applying strict capital gains tax reporting requirements.

>Can Bitcoin gain that level of trust amoung its users to be successful.

The massive public and institutional buy-in over the past 5 years suggests that trust in its cryptographic security is not what is holding it back.

Bitcoin, from its inception, is part of a political battle, not a technological or economic one. Read the Satoshi white paper. Paul Krugman is saying that it wont be successful because the banks and government will fight it, and his social status is dependant on him being part of that fight. Do you think Krugman would keep all his exposure and prestige if he went off the reservation and criticized the banks and the petrodollar? No way.

Mounir al-Motassadek: Germany releases 9/11 accomplice
Here is Bitfenix's cold wallet address:

https://bitinfocharts.com/bitcoin/address/3D2oetdNuZUqQHPJmc...

They have about 934 Million in BTC, having had as little as 869 Million USD recently. Their tether liabilities are between 2.5 and 3 Billion USD:

https://coinmarketcap.com/currencies/tether/

It has long been asked how a token can be pegged to 1 USD without any actual USD.

The reality is that it can work if your balance in other currencies doesn't go below the average price you bought them at. The more the price of btc goes down, the more btc they have to give back when people exchange their tethers for btc (you can't exchange them for USD).

Two dynamics work in their favor:

First, exchanging tethers for btc means buying btc, which makes the price of btc go up. If people buy the btc so that they can exchange it at real exchanges for USD, then this effect would be temporary and you would see a disconnect between the price of btc at Bitfinex and real exchanges like coinbase. Two days ago the premium on Bitfinex was about $100, now it is about $400 higher than coinbase and bitstamp.

Second, what many think originally happened due to the stark correlation between tether creation and btc price jumps on bitfinex, was that the creation of tethers and subsequent transfer in bulk to bitfinex's exchange caused the btc price to rise. Now not only do they benefit from creating tethers out of nothing, they get the exchange commission on top AND get to create the illusion of demand. This illusion of demand was seen to work extremely well on unsophisticated investors during the run up to 20,000 USD per btc, helping to create articles, fear of missing out and general hysteria that brought in more unsophisticated investors buying in to something they did not understand.
Code is meant to be read first and foremost by humans.

As such, code should be written for clarity and presentation. To communicate intent. Automated tools destroy this human/code connection. They reduce your coworkers to simple cogs in a machine, rather than authors and communicators.

Just did some rough math on this. He's reported to have 55% of SpaceX, recently valued at 27.5B [1], and ~19% of Tesla [2], most recently at ~44B, for a combined net worth of ~23B (before any debt). He therefore definitely couldn't personally buy out Tesla at current prices, and any significant investment of personal funds would require the sale of SpaceX shares.

Also, much of his liquid pocket money has come from loans backed by his Tesla Stock. This could be a problem if Tesla stock price drops too much, as the stock he has pledge is required to be no less than a multiple of the money he has borrowed. [3]

Disclosure: I am short Tesla.

Hi It's Kenneth from VS Code.

We have looked into this, and haven't found an intentional change that should change your opt-out settings. This shouldn't happen.

We have two theories:

1) Your settings file was deleted, which means that you would have lost all of your settings, and not just the telemetry setting. This can happen if the AppData or ~/Library/Application Support was cleaned up.

2) One of your installed extensions updated the settings either accidentally or on purpose. This would require further debugging, and a list of your installed extensions.

To help debug this further, it would be great help if you could open an issue on Github, https://github.com/Microsoft/vscode/, with more details about your OS, VS Code version and installed extensions, so we can figure out what happened.

Thanks!
