> markets are reaction to this response emotionally

I don't think so. The material takeaway is Tesla will need to raise new capital in 2018. The numbers implied it. The market previously guessed Musk had some genius plan to avoid it. On this call, the lack of such a plan became evident. Dilution and/or increased default risks/interest costs are being priced in.
I would have loved to try it, but it looks a bit too heavy (.js size, even minified is 30KB+, and looks like jquery is needed too?) foe my 197KB homepage, and I am actually working to trim off few dozen KBs by not depending on jquery slim.
Adopting a growth mindset for engineers
There is a big difference. You're only considering the "slowness" from the application perspective of querying a table without the index.

You need to also realize that database server itself takes a load hit when it kicks off these operations on large tables. I'm not sure on PostgreSQL, but I know sometimes you can not immediately cancel these operations in the middle on MySQL (it also takes time to revert).

With gh-ost you have full control over how fast this process goes and can even pause/resume it if you're experiencing issues.

But let's say it IS instantly cancelled. You're also ignoring the fact that you will take the same hit on any replicas if this statement is successful.

Some production environments don't take kindly to having all replicas lagging as the replication thread is blocking on the DDL change. My team has the luxury of being able to have our entire production environment served by a single master server (though we avoid it as much as possible), but it won't be long before we outgrow that and require at least one up to date replica. Many teams are already in that situation and for that, gh-ost is a godsend.

I think a perverse sense of ABI stability, in this case. Don't want to change expectations for any userspace program, ever. getrandom(2) theoretically provides the actually useful behavior.
Some background on this: NASA deep space missions have historically used radioisotope thermal generators powered by the decay of the exotic plutonium isotope Pu-238. This isotope has a good balance of lifetime (87.7 year half life) and specific energy (0.5 watts/gram). It is non-fissile -- no risk of criticality. It also decays solely by alpha emission, so there are no problems with shielding the rest of the systems from e.g. gamma or neutron radiation.

American plutonium 238 was formerly produced using Savannah River Site reactors that primarily produced materials for nuclear weapons. With the retirement of those reactors in 1988, and the American nuclear weapons program going to maintenance mode, NASA lost the side-benefit of Pu-238 production using the weapons infrastructure. Deep space missions requiring RTGs had to subsist off of historical Pu-238 stockpiles and additional material purchased from Russia. But the Russian supply has run out too now -- apparently they aren't producing more of it either.

American plutonium 238 production efforts resumed in 2013:

http://www.spacesafetymagazine.com/aerospace-engineering/nuc...

With NASA now paying the full cost, including fixed startup costs, Pu-238 is extraordinarily expensive:

NASA and DOE have estimated the rebooting will cost between $75 million and $90 million over five years. According to NASA officials, the agency expects to have 1.5 to 2 kilograms produced per year, starting 2018.

The high cost and limited supplies of Pu-238 have spurred the search for alternatives to Pu-238 RTGs. A few years ago I remember reading that the European Space Agency was going to try to design its own RTGs using the less powerful but more abundant americium 241 instead of plutonium 238. But a quick search just now doesn't show any concrete development effort.

This Kilopower reactor is an alternative to RTGs for some mission profiles -- in fact offers more power than RTGs and uses cheaper nuclear materials. (Highly enriched U-235 isn't cheap in an absolute sense, but it's far less expensive than Pu-238. And the security of supply is effectively backstopped by its use in reactors for the US Navy.) It can offer ample power for very deep space missions at a cost significantly less than using years' worth of Pu-238 production.

Improved photovoltaic cells have also enabled missions further from the Sun than they could have supported in 1988. The Juno mission, which entered Jupiter orbit in 2016, relies on PV instead of RTGs. It seems plausible that further evolution will eventually push PV's reach out to Saturn missions. But PV is not currently plausible for missions beyond Jupiter, and it is reliant on slowly-evolving battery technology for surface missions on Mars. Martian missions using PV also face significant problems from cell-obscuring dust. This reactor seems too large to be conveniently integrated in a Martian rover, but enabling non-surface missions to avoid Pu-238 use may mean more can be reserved for future rovers akin to the RTG-powered Curiosity.

What's the alternative? As others have pointed out the results as they stand aren't that good and, as you point out, other search engines have their own incentives to push stuff to the top.

Since the scoring system can be customized I think we can eventually figure out a way to deal with bots but it will always be done in a way that has to treat all domains equally. I think it would be appropriate to have our scoring system regularly audited (along with the rest of the code) to ensure that we treat all domains equally and that no modifications are being made to the rest of the code in regards to privacy.

If, after all of that, you aren't satisfied then by all means you can run your own instance and order the results as you see fit while blocking others from upvoting/downvoting.

EDIT: BTW, I am not suggesting that the voting system is set in stone. If there is a better way then I'd love to hear it! I do understand the drawbacks to the users voting and I hope I am not coming across as being completely inflexible on this point. I just haven't come up with a better alternative and haven't gotten much in terms of concrete suggestions.
Slightly offtopic, I recently looked at all top free internet websites/services that I use and wondered which of them I would miss if advertising dollars dry up. For me, it turned out to be stackoverflow and Google. I truly hope stackoverflow is a profitable venture at this point. I hope they have been trying various avenues to make money but no o no one has any info on profitability. Job ads pay well, but there is fierce competition there.
Er, why is asking for something fundamental to running a business (i.e. "How much money do you have/need?") a partly boring/boneheaded/uncool question?

I am always amazed by how many people get into this "Beat the system and make tons of money" mindset.

If there's anything that has proven itself time and time again, it's that people who seek immediate wealth, and who fantasize about their "million dollar idea", are absolutely not the kinds of people who become successful and wealthy.

The people who become devoted to a field or a technology - who make the business their passion, and focus on filling a need - these are the people who earn a fortune.

You can't just make money by trying really hard to be rich, unless, of course, your business model is funneling cash off of suckers with a predatory get-rich-quick scheme.
For the sake of society, I hope Musk succeeds. We've spent too much time as a culture celebrating fairly useless achievements and being unwilling to dare to do the things that will truly take us forward.
Well-run meetings really depends on your company's culture and management support.

I find that a lot of bad meetings are driven by procrastination: The person holding the meeting is doing it as a way to get out of work. Other times, the person holding a bad meeting has an inflated ego and thinks a whole bunch of people need to pay very close attention to something that doesn't really matter.

If your organization doesn't have these problems, then great!

Show HN: AntsDB – a database virtualization software for HBase
AntsDB is a database virtualization software/middleware that provides a low latency high concurrency virtual MySQL layer on top of Hadoop HBase. It is wire compatible with MySQL and supports core features such as all DMLs, most DDLs, transaction control, index, full text search, MVCC, row and table locks etc. It is designed to make HBase, or any data warehouse, an OLTP database.

Up to date, it can work with many MySQL applications such as MySQL console, MySQL command line utilities, MediaWiki, SonarQube, DBeaver, phpMyAdmin, Squirrel SQL etc. I've benchmarked it with YCSB. It is significantly faster than mainstream relational databases. Results can be found at http://www.antsdb.com/?p=171.

I started this project a few years ago with a couple of questions in my mind: (1) why do you need a front-end database if all it does can be done by a middleware (2) I like the scalability of Hadoop but I hate missing the nice features from the traditional relational database. Why can't I have both? (3) How far can you go with Java?

Now I believe I have limited success with my experiment and I'd like to share it with the community. The project is open source. GitHub url is https://github.com/waterguo/antsdb.

You are welcome to try it out or use the code in your own projects. I will be very grateful if you can give me some feedback.

Asking how he is going to reign in capital expenses, when their burn rate will drain them of cash in 8 months is not being spiteful.

It's called being an investor.

Refusing to answer that question, is either being spiteful, or disingenuous. It's a bit of a red flag.
Yeah I concur. The kind of numbers they're talking about are no joke.

Investors immediately responded to Elon's hubris in kind by severely punishing the stock. Seems the joke is on Musk.
If you dismiss every data point (anecdote) you come across, one at a time, of course you can eventually say there's no pattern: you dismissed all of the data.
If your goal is to post problems and associated solutions, yes it is better than a Wiki.

First, it gives you a template to post in - you are not given a blank page and told "document this"

Second, it encourages you to document single, smaller, focused pieces of information. You're not being asked or expected to write a multipage document, you're being asked to write a single entry in what essentially is a crowd sourced FAQ.

One thing the SO approach also does is that it respects the content that each person posts. If I post an answer, only I can modify it. Nobody will modify my answer to reflect what they think, and make it seem as if I was presenting a different solution that what I suggested. What people with alternative ideas CAN do though is post alternative answers, or comment on my answer with suggested changes.
Ah shit, that was my mistake, I didn't just pick an in demand niche that no one else had already identified and filled. Good thing I had this safety net to fall on after I spent my savings that took me 30 years to build up to make an attempt on a business.

As it stands in the US currently if you don't receive help from your parents or some other rich connection, the average person is winning the lottery if they start a business and succeed.

Did he post anywhere that he has officially been diagnosed with BPD? I believe he said he had "bipolar" on Twitter at one point, though I remembered it seeming like he was referencing a cycle like mental exhaustion from heavy mental activity times to slower, more depressed states.
AT&T regularly assigns my phone an IP in 10/8, instead of using 100.64/16 as they should [1]. IIRC, they used to even have the gall to use 172.16/12, which is crazy when you consider the amount of corporate networks using those addresses.

This caused issues where my phone would try to get on wifi, but the DHCPACK would be sent along on the existing interface rather than the one coming up. So the wifi icon was continually bouncing back and forth. My only solution was to go into airplane mode and bring the cellular down before bringing the wifi up. I don't think Android ever addressed this issue, and I had to switch around the entire subnet to avoid the conflicts.

If I knew enough about how Android worked, I'd write a patch to have all android interfaces in their own linux netns, with the dhcp client exec'd in that netns, that way you'd never have to worry about this sort of conflict.

Hedonic bliss is very different from, say, extremely motivated high-optimism. The latter can easily get you hospitalized and medicated for mania. People around you will not accept it unless you have a lot of charisma and status to back it up (like Gary Vaynerchuk or Richard Simmons). The former will probably make you an unmotivated shut in, like a junkie with an endless supply.
They are not safe. They lack their own biological shield, and thus require the core section to be buried underground, as can be seen in various demo images. Even then, I suspect you wouldn't want to be too close while operating. They also lack other safety systems a commercial nuclear power station reactor has, having only a single control rod. This makes sense for an extraterrestrial reactor, as transporting mass to Mars is very expensive.
I think in general, it's very difficult if not impossible to realistically explore the counterfactual of "what would this property be if not for Airbnb".

However, in my neighborhood long term 12 month lease rentals most definitely seem to be being turned into Airbnb rentals. I live in Tahoe, so this isn't necessarily going to generalize to non-tourist areas. In the last five years there has been a steady conversion -- I personally know of four in my immediate neighborhood. (As in, they were long term rentals converted to Airbnb. I know the people that were kicked out of the long term rentals) When we'd recruit new people to Tahoe there used to be numerous options for local housing, things have gotten so bad that the company I work for opted to buy a condo to provide temporary housing for new recruits while they look for more permanent accommodations.

An additional (also anecdotal) data point: our realtor told us that investors looking to convert homes into Airbnb are very active right now.

On the plus side (potentially, not everybody agrees) Airbnb also seems to have converted a number of second homes that were previously unoccupied most of the year.
I'd add a tad of context to my original comment. I probably have a lot of hard feelings against companies hiring behavior, some justified, some merely emotional. Karat however went over the top. They're trying to be extra-nice by triple checking that everything went well, but don't follow up on negative comments. It's not rocket science to properly define test cases and supported logic to run them so that the candidate focus on the implementation, the screening implements it, but not the timed phone call. Also, tricking candidates with edges cases not mentioned orally but not written is borderline dishonest.
Agreed - this is for many kinds of people, not just technical people.
Interesting insight -- thanks!

I agree with others here on the security vs. performance and security vs. binary size trade-offs. As a thought experiment I wondered at what point it would become a hard decision if I were in his shoes. I think a 10% performance hit would make it a harder decision for me, but at that point I would probably still err on the side of caution and prioritize security.

Of course it's possible this is exactly one of the reasons Igor owns something like 7-Zip, and I don't :-)

Repeating this cliche is not a counterargument to a regression analysis. If you have specific covariants that you think better explain their results, present them. Otherwise, "correlation does not imply cause" is little more than a lowbrow dismissal dressed in a labcoat.
I agree — I don't think I would have given this post any attention otherwise. Impact is old news. Its open sourcing is not.
I'm not defending Elon's behavior here, but speaking more generally: if you're in a place where you need to maintain maximum productivity for a while, because a deadline has slipped for example, meetings can turn into a massive time sink if you don't act like a total nazi during them.

In so many meetings, people just want to hear themselves talk, whether to offer some opinion, reiterate some point, or ask some useless question. If your goal is, "end this meeting as quickly as possible so I can start fixing the things that need fixing", often the other people in the meeting become your careless adversaries.

edit: I regret trying to raise this point in a thread about Elon Musk. :-(

Musk's history of lies - https://twitter.com/wolfejosh/status/989258303640408071

It's far more likely that the stock continues to deteriorate, and that there's a margin call at the $230 level (https://seekingalpha.com/article/4168224-musks-personal-fina...) and that Tesla is liquidated by the end of the year.
A little more context from the WSJ article (https://www.wsj.com/articles/teslas-elon-musk-turns-conferen...)

>“We’re going to go to YouTube, sorry. These questions are so dry. They’re killing me.” He directed the operator to take questions from Tesla investor Galileo Russell, whose HyperChange TV YouTube channel features a video titled, “Why I Bought Tesla Today at $255/Share.”

>Mr. Russell, who had campaigned to get on the call usually reserved for analysts, got more than 20 minutes from Mr. Musk. The first of his dozen or so questions: When will Tesla launch its own network of driverless cars?

>“Thank you for an interesting question,” Mr. Musk replied.

It's especially cringey because if Musk was honest about that interesting question he would say he has no idea and should really be focusing on ramping up production. Instead it's a softball question that lets Musk proselytize on the radical world changing work that Tesla is doing...
That only holds if desirable men prefer to not be married.

Also, being married doesn't prevent a man from having sex outside of marriage.
The emotion seems to have been mostly on Musk's end of the line.

> But then, acting within the confines of normality isn't really the trait that may bring the dawn of a new era of humanity.

Tesla is not bringing 'the dawn of a new era of humanity', it's an electric car manufacturer. They came and went and now they're back.
In the case of vaccines specifically, there is just a surprising amount of things we still don't understand.

Vaccination is positively ancient technology (Smallpox circa 1796), but it is still difficult to say why e.g., some vaccines are broadly effective at producing immunity and some aren't (and what the factors at play are in the recipients), or why we can produce successful vaccines to some diseases and not others.

A specific example: the efficacy of BCG vaccination (tuberculosis) varies by manufacturer and the reasons for why that is are still unclear.

There are a number of large NIH-funded initiatives that aim at understanding the complex cellular and molecular interactions that result in immunity as a result of vaccination under the Human Immunology Project Consortium (a bunch of high profile papers in Cell, etc. over the past few years).
New Class Naming Rules in Ruby
Yeah. There is so much wishful thinking in all cryptos and that's what ultimately drove me away. So many people don't understand the technology or what it really means to have a system running at global scale yet they are sure that someone else will solve the problem for them.

This actually gets at a deeper problem in our society. Lots of people justify their unsustainable lifestyles by thinking that some day technology will make it sustainable. It doesn't work like that. When new technology happens you won't go sustainable, you'll want more.
>If a rocket explodes with nuclear waste on board, the waste would spread over a large area.

Space is very big. Is it actually likely that said waste spreading would even be noticeable?
Having watched clip in the article and given I don't have any Tesla stock. Additionally having been an operations manager I have some sympathy for Musk. Every Tom, Dick, and Sally has an opinion but very few have the know-how to help. But in today's world who needs to be an expert to comment or pass judgment. On the one hand we have CEOs who chase the quarterly earnings at the cost of long-term sustainability. Musk says he isn't interested in short-term (in not so many words). Either way, you going to piss someone off. Like I said I don't have stock in the game.
The Flamethrowers aren't a Tesla fundraiser. He's "getting away with it" because The Boring Company is private.

If by "flying close to it" you mean flailing end over end into it then yes.
what about REITs?
What is the 1% rule? As a landlord I usually assume 0.5% per year.

So a million dollar condo would be 50K a year, or about $4200/mo, which is exactly in line with current nyc rents.
