>>> What are the practical, non-entertainment benefits of magnet balls?

Who cares? In a free country, any benefit that I see for myself would be enough to allow me to purchase the item, without explaining it to you or anybody else. How is it that you decided you have the right to define what is and is not beneficial for me? What gave you that right? How is it fair for you to tell me "I think you're not smart enough to handle a couple of metal balls without killing yourself" and feel all smug and righteous as if you've saved my life, instead as a petty busybody who just made my life (and a life of thousands other people) a little worse for no reason at all, while shuttering perfectly good company, and causing a lot of loss and waste of money and effort? What exactly allows you to feel you're being anything even in the general direction of "fair" when you take on yourself to decide my needs for me? Do you enjoy other people telling you what is and is not of benefit for you?
How do you determine that being a woman is the reason for somebody not being taken seriously?
It's not that it won't disclose the sale price per share - it's that at the time you join the company, the sale hasn't happened yet, and nobody can predict the future. Knowing the sale price X years in the future, when and if the company actually gets sold or IPOs, doesn't help you evaluate the company now.

The value of understanding your % ownership is that you can do your own math on what potential sale prices are likely and then see if it ends up being personally worthwhile to you in those scenarios. The company's quite capable of picking an arbitrary sale price and then doing the math to tell you what the sale price per share is - but given that they have a vested interest in hiring you for the lowest stock grant possible, they will probably pick the highest conceivable offer and then divide that by the number of shares currently outstanding (ignoring dilution), because they can't predict the future any more than you can and, when asked to make things up, are under no obligation to make things up that are more favorable to you than them.

I had a friend visit SF from NYC a couple weeks ago, and it blew my mind that he continued to use taxis instead of Ubers. Here, the decision seems clear-cut: calling a car with a phone is cheaper, faster, and more convenient. However, in NYC the streets are so saturated with taxis that waiting 5 to 10 minutes for an Uber instead of hailing a cab immediately seems absurd in most day-to-day situations.
> Pawns move two squares only on the first move of the game not the first move of the pawn

Can you elaborate on this? I've never seen any claim to this effect, only that a pawn on its starting rank has the option of moving two squares (but cannot use that to jump over or capture a piece) (e.g. as stated http://en.wikipedia.org/wiki/Pawn_(chess)). Are these different claims or am I misunderstanding?

> You can't promote a pawn the move after it arrives on the 7th rank, you have to wait a move

Same here. "The new piece replaces the pawn on the same square, as part of the same move" (e.g. http://en.wikipedia.org/wiki/Promotion_(chess))

I'm only showing wikipedia cites to indicate that if these are wrong they are widely spread, and hoping that you have better cites.
You can't blame publishers for going with click-bait titles, particularly if the article actually delivers what the title promises.

As for not mentioning Apache.... That is bad. I'm not sure what they could put in that article that would speak to their audience though.
hadn't realized it had been open sourced so recently, just 8 days ago was the HN discussion on AerospikeDB being open sourced:

Hate to see what happens when a bug causes the wrong motors to fire and the thing breaks all of your bones. Be awesome to use one though all the same.
Both questions don't indicate a belief that somebody can't hack, just that it is less likely for that person to be a hacker. That doesn't imply anything about skill.

And CEOs are not usually hackers anyway.

Likewise, sexual interest doesn't indicate a low opinion of somebody's skills. Otherwise only stupid people would have sex.

If female CEOs are only taken serious once they are successful, how did they become CEO in the first place?
It seems the Rust team is really optimizing the language for ARM chips.
Do people actually use ORM-generated migration in large production environments? In my experience, schema mods to big production tables need to be planned out carefully and run by hand on the inactive master db (using mysql mmm replication terminology) in order to pull them off without downtime. You can't just have the next app push blindly start doing ALTER TABLE statements. Perhaps there are clever schemes modern ORMs use to package up the migrations to be run on the inactive master? I honestly don't know, but I had the impression that automatic migrations via the ORM were more or less unusable for anything nontrivial.
How do you separate all your projects and different MySQL dbs? what if you need different versions?

The Hobbit still most likely doesn't use rolling shutter sensors, but I'm willing to be proven wrong.
That is just an empty claim, though. Is there any indication at all that it is the case?

Maybe some women CEOs feel they are not being taken serious because they are women. But if CEOs in general are not being taken serious until they are successful, how do those women determine that being a woman is the extra reason they are not being taken serious? And how did they get to be CEO in the first place? Somebody has to have believed in them?
Huh? Can you describe a scenario that you couldn't implement with tunable consistency levels?

Mostly the limitations people come up with with Cassandra are around cross-row ACID, which if you really need it you can do with LWT, though in practice the better solution tends to be to just denormalize in to one row and/or NOT actually require cross-row ACID. It generally isn't what you really need anyway. Most businesses don't really shut down just because they can't achieve consistency.
Vulcan looks neat because it is configured centrally via etcd (thanks CoreOS). Simply push changes to etcd and vulcan hosts ingest the changes. Though, it is hard to imagine a much better http reverse proxy than nginx.
But isn't being seen as an Apple 'clone' a huge win for the company? In China, Xiaomi is distinguishing themselves from their competitors by being consistently associated in the same sentence as Apple, whereas the others are 'just Android'. It would be a PR coup for Xiaomi to be actually sued by Apple : They'd be constantly in the news as being seen as comparable to the most prestigious brand available. Xiaomi doesn't mind the controversy : It all reinforces the idea that their brand is in Apple's style-bracket.

The article isn't claiming that faster speed == safer. It clearly states that raising the speed limit has little effect on the speed that most people travel. The only group of people whose driving speed it significantly affects is the 10% of people who follow the speed limit exactly (who are usually the slowest drivers). Therefore, by raising the speed limit, a large majority of drivers will drive at the same speed (no faster), but the slowest drivers will speed up and the speed differential drops, making the roads safer, as your linked article agrees with.

There was little evidence presented that justified the assumption that most people won't drive any faster with a raised speed limit, but if we take that as true, then its conclusion is consistent with the research you linked. It is NOT making the claim that driving faster is safer. In fact, it again clearly states that in an ideal world, everybody would just travel at slower and safer speeds, but that we can't effectively enforce such a low speed limit.
Women are deceived more than men in distributive negotiations
These things happen. An ex-girlfriend's 8 year old (at the time) swallowed two small kitchen magnets (they were the small type embedded in what looks like a push-pin top). At the time it was suggested by the doctor that he might have had pica (http://kidshealth.org/parent/emotions/behavior/pica.html) and that's why he ate the darned things.
Right. That was sort of my point, I understand it is useful to consistently lift and move heavy stiff without fatiguing oneself. I think if you were to improve it to say, 250kg it would fit a lot more usecases. Overengineering, in my opinion, would be asking for an iron man suit.
Since when has investing in cyberwarfare skills become a substitute for writing correct code?

Instead of thinking long term, and learning to write open, correct code in sane languages, the continued emphasis is in continuing to ship bug-ridden, untested, source either open with Linux, or closed source with Windows, in an insane languages like C, then announcing that investments need to be made in cybersecurity because the planet needs to be saved from hackers.

Why not focus on getting things right in the first place?
That's 11 injuries and 0.3 deaths per year. Bathtubs claim about 80 fatal and 100 non-fatal drownings per year.

Judging from this data, assuming the risk stays the same over time, you have to play with magnets for roughly about 1000 years for your risk to be one micromort[1]. Same one micromort risk is assumed by drinking two glasses of wine or walking for 17 miles. Playing with a magnet for a year is as dangerous as eating a banana (bananas are radioactive).

Came here to say this. RedBeanPHP is a great ORM with several advantages over stuff like Doctrine:

* it doesn't require you to learn new language. The API is very simple

* it encourages using SQL when needed. Need to add a special WHERE query? No problem. You want to make a custom select? Just use R::get() method

* it doesn't alter your scheme more than it should. There is only one rule - linked table names (m:n relations) use an underscore. That's it.
> But in the same way that Godaddy uses buxom female models to promote their products (which works well for them) and some people find that distasteful, I find this distasteful.

Bingo. I find it odd how many people here either seem to be missing your point entirely, or are just trying to be contrarian and '1-up' you by being saying it's effective' (virtually implying that it's therefore 'ethical'), when that wasn't even what you were arguing against to begin with.

If this were a post calling out godaddy about their usage of women (as per your analogy), then most comments here would probably be agreeing with you, but since it's something more 'controversial' and closer to what we as developers do for a living, then suddenly your actual point isn't as important anymore... I don't want to attribute it to a lack of 'self-awareness', but it is a bizarre phenomenon.

Whenever it's convenient, HN will always reliably argue against the use of 'morality' in arguments, because it's just so 'subjective', that it's not even worth bringing it up at all (which is just lazy critical thinking IMO, but oh well).
I suspect that when you get up to 250kg you run into stability issues as much as strength issues. Even if you could lift it easily, it would be really tricky to hold it in a way that you won't tip over and drop it.
That's a weird way of doing it right. So you can buy it if it says "very serious magnet spheres, definitely not a toy, thinking and relieving stress while touching them is absolutely prohibited!" then it's ok, but if it says "adult desk toy for mental stimulation" then it's banned, even though these are exactly the same things and in both cases the seller has zero control over how exactly they are used?

Of course, makes sense.
This is quite a challenge to Apple - compete with a chinese firm without resorting to an army of lawyers. Apple has already made a nice pile of money selling iphones, time to invent or face powerful competition that doesn't fear US patent system.
Equation 'can predict momentary happiness'
actually my argument is based more around 60 mph average speed because that's more or less the average speed on highways and people spend a decent amount of time driving on highways and the like. Also, the increased fatality rates were concerning a rise from 60 to 70mph.

Obviously if we're going from 15 to 20 the numbers change. But at the same time if people were on average driving around at 15mph on average car accidents wouldn't be such a big issue, instead of the leading cause of death among teenagers.

actually with lower speed limits you would gain more time by going 10mph faster. For example, if people were driving at 10mph on average, going 20mph would half their transit time. The point is that the speeding people commit usually doesn't earn them much more time, but disproportionately endanger themselves and those around them at higher speeds.
We have our top men working on this.
Yes I read that, but I imagine that means that the total cost is at least $85 million. R&D and components done/made elsewhere aren't going to be figured in to that $85 million.
They actually called it at T-0:46, just didn't update the counter.
So you know anybody can buy it very easily on different site, and you still applaud shutting down responsible US companies taking all safety precautions including customer education, even though it would not affect availability of the thing you consider harmful in any meaningful way.

I think now I see where War on Drugs comes from. They do the same useless thing all day long, at great cost and great harm to everybody involved, and still somehow believe they're doing good work, despite the evidence screaming in their faces for decades now.

I think, the problem is in all-or-nothing approach when discussing that topic. It's always "abstract pure SQL" vs "abstract pure ORM", but I think the solution is in reasonable compromise between them.

First, it's definitely bad idea to write ORM that works with absolutely any database schema. If you accept some limitations in schema design (and some in model layer too), you can really benefit in more simple ORM design.

For instance, you can eliminate partial load at all, breaking stored entities into separate aspects in separate tables and using some tricks for fetching associations (see below).

Second, ORM should be as lightweight as possible, so you can really use it and not fight it.

There are things that just should not be used in ORM, if we don't want to solve some complicated performance problems. I believe, it's really bad idea to use auto-generated SQL JOINs on ORM side, it's very hard to control and optimize them. There is simple and clever solution by Jakub Vrana (https://www.facebook.com/jakubvrana/posts/415359675151430), that works really good if implemented carefully on ORM side. When you really need JOIN, you can use VIEW on database schema side or (better) use some kind of denormalization.

You can optimize VIEW on SQL side, you can move from views to denormalization without breaking model layer etc.

Using stored code on SQL side is good, you can maintain your database without any special client tools or code, and you could automate a lot of denormalization using triggers.

Ask HN: Steps to take near project completion?
Hi. I'm sorry for the broad title, but I'm feeling a bit lost here. I've been working on a project for quite a while and I don't have any mentors, co-founders, or even acquaintances with technical or entrepreneurial interest whose brains I can pick.

The project I've been working on -- without going into the real nitty-gritty -- is a general purpose social network. I believe that it has real potential, but in moving forward, I'm going to be heading into territory I'm very unfamiliar with, into a very fierce market without any entourage, whilst operating on a shoestring budget.

Some of the specific things I really want to get a handle on are the following:

1. What are the best ways to recruit testers, or preferably, those mythical, golden early adopters that understand that lots of things can break but still stick it out and give tons of useful feedback?

2. What are some launching strategies that work for broke people? (Not college student with rich parents broke; "turtles all the way down" broke.)

3. If there were some kind of "app readiness" checklist, what would be the real make-or-break items on it?

4. What are the good venues for soliciting pre-launch discussion / brainstorming? Before fully launching, I'd like to do something along the lines of posting several screenshots or a quick video tour. This would be posted alongside some textual narrative describing the more important features in greater depth. My aim would be to gather some first impressions and ideas for enhancement before more serious testing or a full launch. Is this unnatural?

5. Any good advice for dealing with pre-launch jitters or the "I just gotta add one more thing" feeling?

Thanks in advance; I've been reading HN for years, and this is really the only place I could think to turn for this kind of advice.
The OP wrote: "What I didn't mention in my post was that I did use SQLAlchemy Core to write some pretty complicated queries."

What you seem to have read: "What I didn't mention in my post was that I did use SQLAlchemy Core to write some pretty complicated queries and didn't use SQLAlchemy ORM at all."

It seems to me that it would be more plausible to read: "What I didn't mention in my post was that I did use SQLAlchemy Core to write some pretty complicated queries, in addition to using SQLAlchemy ORM."

HIV and Malaria are both broadly endemic in Africa, including some conflict areas - it's going to be a long tough slog to rid the world of them.

This breakout of Ebola is geographically isolated, and its nature (short infection period, burns out quickly, hard to catch) - makes it something that a strong effort right now would absolutely shut down.

Regarding modeling the disease - yes, of course - from that perspective I can see how useful it would be to model, but the assumption should be pretty explicit. I.E. "Assuming traditional regional responses to this disease, this is what we would expect" - to make it clear that this is a model, and not a prediction.

The primary wins are:

* Your servers are all kept in a known state that is described by your code. If you don't have configuration management, you have to remember that postgres is installed on X server and has Y configuration. Which is ok for simple configurations but quickly becomes a total mess for semi-complex configurations.

* You can go from a clean server to a fully fledged working server (or set of servers) in a single, repeatable step.

* You can remove repetition from your code base and decouple your server configurations. Database password needs to be used in six different places? No problem. Specify it in one centralized configuration file and then just use template variables to make it appear wherever it needs to be upon deployment.
Good to see that you can take facts pipy -- and thanks xi for doing better than I did in discussing.
