Lab reports and notebooks are not what makes "Science". Science is developing a hypothesis, performing an experiment, observing the results, and re-evaluating your hypothesis. That's it. It doesn't matter if you write it down or turn it in.

Kids do science all the time.
Chemical engineer here. What haven't I done?

- Shattered stuff with liquid nitrogen: PB&J sandwich, bouncy balls, etc.

- Melted various metals in crucibles over Fisher burners. Got burned a few times when I didn't realize the crucible lids were still hot.

- Made ferrofluid. Not particularly dangerous, but very cool stuff. Search for it on Youtube.

- Thermite reactions. These were fun. You had to start them with sparklers (or a lit magnesium strip).

- Lit hydrogen bubbles (we used to have "fire Friday")

- Chlorine and sodium reaction to make salt

- Nitrogen triiodide (an explosive; can be detonated with one alpha particle)

- Aluminum sulfur reaction: This one was interesting; the science lab book specified a small zinc sulfur reaction. I wanted to up the ante with aluminum and sulfur. Per the Wikipedia page which I read after the experiment:

"This reaction is extremely exothermic and it is not necessary or desirable to heat the whole mass of the sulfur-aluminium mixture; (except possibly for very small amounts of reactants). The product will be created in a fused form; it reaches a temperature greater than 1100 °C and may melt its way through steel. The cooled product is very hard."

Yeah, my friend and I finely ground up a HUGE batch of that aluminum and sulfer in a mortar and lit it in the fume hood. It looked like a rocket was going off. What we also didn't realize was that the product, aluminum sulfide, should NOT go in water, and water is exactly where I dumped the stuff. It stunk up the lab with hydrogen sulfide. I wonder how many brain cells I killed with that.

- Burned some chromium compound. Can't remember what it was, but when I showed the instructor the product, he got really upset. He began scooping it out of the sink because apparently I'd created a carcinogen.

- Found a container of mercuric (II) nitrate. It was the one thing the instructor wouldn't let us play with.

That was all in high school. Mostly in the fume hood. College was a lot more boring (we had to wear goggles and gloves to handle Kool-aid), although I did accidentally spill a container of concentrated sulfuric acid all over the place in organic synth lab.
Someone did that at my highschool with butyric acid. The smell was so bad that a few people added to it by actually vomiting.
Why are people against banning civilian ownership of all guns in principle?

I had some very nice experiences as a child with a pellet gun my father bought me. I later had a lot of fun experiences with him at a shooting range with real guns. I don't think I got much more from the shooting range than from my pellet gun.

What's the motive of gun ownership, besides concealed carry and hunting?
Psychopaths are notoriously difficult to treat. Most of the reason for this is that, by and large, they simply don't want to be cured. This isn't to say that they're enthusiastic about being psychopaths, but they don't see it as being problematic enough to be worth the trouble of changing. In other words, while they may not necessarily want to be psychopaths, they don't particularly want to be not-psychopaths either.

If you're actually worried about being a psychopath, then clearly you want very badly to be a not-psychopath. If it's that important to you, then you're missing one of the critical markers of psychopathy.
If the premise is that surrounding yourself with other startups is not sufficient in itself to accelerate your company's growth, then it's trivially true and of little value.

If the premise is that there is no value to be added from startups seeking high growth from surrounding yourself with other startups, then I have to disagree.

Sure, you won't get high growth if you spend all your time hanging with brogrammers and drinking at industry social events. But learning from smart people is something that happens almost by osmosis if you mix with a good selection of other startups.

Being around when one startup falters and the founders and team are looking to join something interesting means your network for recruiting grows, and some of the best team mates I've had have been when one startup died and folks joined up for another. That's accelerating growth.

Seeing what mistakes others are making prevents you from making and short cuts the path to making the right choices. That's accelerating growth.

If you've got a crappy product and an idea that isn't going to work, and you spend yourself hanging out with others similar to you in that, well, you're not going to do anyone any good. Particularly not when, as I've seen, it becomes a complaint fest about the industry not an analysis of what you could be doing better. Like anyone who's ever worked at a big company will tell you, if you hang outside the building with the smokers bitching about the company, don't be surprised if you aren't the ones doing well at that company.

So YMMV, but absolutely mix with other startups. Pick well who your friends, mentors and models are. It's unlikely that it's going to hinder your growth, unless your attitude was such that you probably weren't going to get that growth in the first place.
Or alternatively don't be afraid of either (after all, your chance of being significantly harmed by a person with bad intentions is nearly negligible in civilized countries if you don't go actively courting trouble - e.g. by being a violent gang member), but support reasonable measures to reduce the likelihood that a person with bad intentions comes into contact with massive force multipliers.
I made some money speculating with options in the public stock market, does that count?

The ones I got at my company have so far netting nothing yet :)
No actually, not really.
I don't see the connection between being anti-banker and the NRA at all - being anti-banker is generally a left-liberal political position, a feeling more at home at Occupy Wall Street. I'm going to assume you didn't bring up "bankers" just because I'm Jewish.

The rest of what you said was equally nonsensical - really, just a slur against gun owners. Do you really think the future leader of an authoritarian, genocidal state apparatus would be anti-government?
Wordpad since 7 is awful. Dreadful. Especially for the usecase of reading \n EOL'd txt files.
Since when did workplaces become bastions of principles, rather than bureaucracies that have a business to run and have to, at some level, apply policies that suspend an employee's worktime freedom as part of the agreement that involves paying that employee's salary?

I work at a small company where no one would care. They also don't care if I spend time on Facebook, Twitter, etc. etc. But not everyone is in a company like that. Big legacy companies hire from the HN crowd too. Whether or not their policies are fair is not always a simplistic argument. However, what is as sure as rain is that trivial violations of those policies can be used as leverage to punish people, when the office politics get dirty and desperate.

It's best to let the worker -- the HN reader in this case -- make the decision whether he/she wants to pick that fight, rather than have them accidentally stumble into it.
Sure, spending time around other like-minded individuals is a Good Thing, and the author of TFA acknowledges that. I think his point was that you shouldn't spend all of you time networking with other startup people. And that's a sentiment that I wholeheartedly agree with.

Unless you are selling to startups as your market, you have to get out of the startup echo chamber at some point, and get out in the trenches where your customers live, and talk to them. If you're selling to manufacturers, instead of going to the nth "startup happy hour" even of the week, how about go the "National Manufacturers Association" trade show or whatever?

On a related note, we should look at our social media activity and ask who our audience is... the HN crowd, and other startups, or customers? Personally, this is something I've just forced myself to start looking at differently in the past 2 weeks or so. I've cut back on tweeting tweets about startups and VC and Silicon Valley gossip, and started tweeting stuff that's, ya know, of interest to the people I want to sell to. It's a seemingly subtle change, but in just two weeks we already have dozens of new followers who represent our potential customer base. That's "permission marketing" at work, and it's something I wish I'd realized a lot sooner.

Anyway, I think the OP is onto something. No, don't take anything as an absolute... and go to the "startup happy hour" from time to time, sure. But don't forget to take time to go talk to customers (or potential partners, suppliers, resellers, etc. Whoever you need to connect with in order to advance your business).
Though my answer should be prefaced with having started at Microsoft in the 90s. Options I've received since then have returned goose eggs.

I thought it was the case that you could never sell it, only keep it for personal use. The entry at the ATF FAQ page (http://www.atf.gov/firearms/faq/general.html) is unclear, and I haven't actually gotten around to reading the statute.
Somebody from teh c-level said, cmon we need to release the addon. Don't waste your time on mathematics ...
I'm sure that is true. However, where do you draw the line between putting out helpful advice, and not saying anything because someone might get hurt by it? I for one am glad to see how-to articles covering things like auto repair, even though someone could end up killing themselves if they screw up a break job (for example).

The car definitely does handle wonderfully for a non-professional driver. There are quite a few complaints about severe tire wear due to the negative camber for people who consistently ride it very rough.

I suspect they engineered the throttle lift oversteer and such specifically for the wider market they were looking to hit. Not just car aficionados, but also people who were EV or green or geeks and such.
You can run very small tests, though. They will not scale, but will give some insight into what the current user base prefers.
You're not crazy, lots of people agree with you. Just please don't be like so many SF residents and complain that all the people "who made SF what it is" are being replaced by tech hipsters making 6 figs, while simultaneously complaining about any new construction in their neighborhoods. It's a hypocritical position. There either needs to be more tall buildings or people with sub 90'th percentile incomes are going to have to GTFO from SF until Silicon Valley collapses.

On the bright side, this is great for Oakland.
i'm using it on first project and it's very nice. they let you export your complete api definition to apiary.apib file which can be parsed with their github.com/apiaryio/blueprint-parser into json and used with your custom server localy. it's also nice for synchronizing between devs, when added to vcs ...
I was under the impression that the idea of cell phones being manufactured by companies unrelated to carriers (as in, not under contract by the carrier, although AT&T may seriously have made their own mobile handsets for a while), implementing published (if even still proprietary) specifications, allowing for the ability to move a handset between carriers, would have been a more recent invention than the cell phone. I mean, put it this way: how do you solve the chicken and the egg problem unless you sell them bundled together?
I'm not a mac fan, nor a mac apologist, but I have to say the current Mac Pro beats all of them ... that is an extremely well designed desktop computer. Really a joy to work with.

For runner-up I would say the SGI Octane2, and for a non-desktop machine, the Sun E4500 was an extremely well designed, well manufactured system. Also a real joy to work with (although weighs something like 100 lbs fully loaded)
This didn't end well for Porsche, though, which is now a quavering vassal of Volkswagen AG.

Like which ones, in particular? The San Jose condo market looks pretty robust to me. There are a few high end condos that have been sitting on the market for a while, but at around $750/sq ft plus HOA fees, they might just be priced too high.
You also have Red5 which is open source and rocks very much. It is just a -tad- less reliable than Wowza which you can't really sell to paying customers, but it's much more fun and customizable.

And to answer your question, Wowza is just a cheaper FMS which also supports other platforms next to RTMP. This article is basically taking the more performant HTTP download mechanism for static content (like YouTube uses) and then hacking it to put a live stream in it instead.
HN is the best tech news aggregator on the net. Where do you think Larry, Sergey, Eric, and Tim get their news from?

There are probably a lot more household tech names on HN than you'd initially expect.
I don't think dfc's first reply or niggler's first reply contain any aggression or hostility whatsoever. As you said, pasting the guideline having done the opposite hours earlier was contradictory, so that was pointed out.

I should say it doesn't help that the first part of his explanation was that if he had followed the guideline -- using email instead of posting -- he wouldn't have gotten an answer as quickly as he would like. This immediately implies that exceptions are to be made as soon as the recommended action infringes on personal convenience, which would of course make the guideline meaningless.

It seems to me that it isn't for testing a REST API but rather for testing something that depends on one without having to deal with real integration issues.
> I enjoy manipulating other people's feelings.

I've had this exact same thought before. I love manipulating people's feelings in certain ways. I like making people have fun. If you're in a bad mood and someone goes out of their way to try and put you in a good mood they have intentionally manipulated you.

Subsequent disclosures suggest that Apple had screwed the pooch over Taligent/Pink, and was desperately shopping for a next-generation OS. The contest was down to NeXTStep, with Steve Jobs, or BeOS, with Jean-Louis Gassee. As I understand it, the BeOS folks held out for too much money (Apple was much closer to broke than they realized) while Jobs settled for power. All else is history.

If Apple's successive post-Jobs CEOs (Sculley and Amelio) hadn't maneuvered the behemoth into a blind alley, NeXT would indeed have faded eventually. But with full access to Apple's resources, the NeXT team were able to turn things around. Sitting on the top shelf in my office, gathering dust (I turn it on every couple of years) there's a cube. A nice shiny silver cube that runs something that looks eerily like NeXTStep, if you squint at it, with a classic MacOS emulation bag on the side. If that's not a statement by Steve Jobs (and a trophy of success, to have the elbow-room to make such a statement) I don't know what is!
I'm sure a lot of laptop computers containing screens and keyboards have been used as evidence. It may be a little too much to ask FBI agents to only take that which contains data, when it's not necessarily always completely apparent.

But yeah, it just got a bit painful after a while.
When I played Everquest I did a very similar thing, except without the ship component. We found an obscure item that was not in any of the well-known databases, which is fairly difficult considering how far reaching they were.

Then we advertised a 'want to sell' considerably lower than the 'want to buy' we advertised in a different zone, both very high prices. Someone decided to make a quick arbitrage sell and found out I didn't want that item at all.

I'm sure some have learned the risks of arbitrage the hard way through these games, among other things.
Jesus! Cliff hanger of the week!

> SF's population density isn't Manhattan's, but it's quite high overall

San Francisco has half the population density of Brooklyn and less than Queens or the Bronx. It's also less than Somerville, Massachuetts or West Hollywood in LA county.

People talk about having more people in San Francisco and they think of Manhattan, but there's actually a lot of room for increased density without looking like Manhattan.
It's interesting to read this post as a "western world citizen" whose country's boundaries rarely (if never) change (well, I don't think a big part of HN ever heard of its country boundaries ever changed in his lifetime).

It felt eye-opening when I stumbled on this issue some years ago. We were building a Google Maps app for a branch of the UN and my boss told me we needed to hide the map's boundaries and use the ones supplied by the UN. I was rather intrigued and he explained how the boundaries used by Google sometimes clashed with the UN's recognition of boundaries for some countries. So I went and loaded the KML using the UN-official boundaries.

Of course, I see some were quick to jump the "Google is taking too much power" bandwagon, but a story is not just on HN to be told but also to engage our minds to reflect. And to me, the story here seems to be about digital recognition of countries beginning to be almost on par with international recognition, and how the digital world, that we thought (hoped?) would abolish the frontiers between men, is still taking these frontiers in account.
Its a trick - hes seeing what type of responses he gets based on his waiting for a set amount of time. We are being tested!
When people have to pay $4000/mo to rent a 3bedroom condo that the person next door pays $1300 on their mortgage (as is probably the case in many areas currently), won't companies eventually think that they can offer far more than just location to potential employees if they go elsewhere? I moved to the bay in 2004, and I was able to comfortably afford a few decent apartments in mountain view/sunnyvale. Those apartments have gone up by 200% in their price because of proximity to FB, Google and other firms.

Everything will continue to get more and more expensive as the cost of basic services goes up and up - eventually you'll start losing a lot of good creative people because nobody can afford to take an entry level job and work their way up. The bar for living "comfortably" in the bay area has been rising extremely fast, and those who have bought a home 20 years ago can live fine, but for young people especially it will be really difficult to catch up. I've had 7 or 8 friends in their 20s and 30s move to the Seattle area for purely economic reasons - a few to colorado and a few to Texas as well.
Telescope dev here. Completely understand why you'd roll your own solution, but just want to point out that Telescope can be made private just by checking a checkbox :)
That's what we should do. What we really do more often is surround train stations with nothing but surface parking over every lot within 500m. Surface parking not only fails to make use of the potential for density in appropriate places but creates traffic and makes it harder to build mixed use or medium density elsewhere.

BART is the single largest provider of off-street parking in the USA. CalTrain seems to be trying to match it.

I don't think it's as simple as that. For example there was a debate about Google Farsi[1]. It used to be Google Parsi which is closer to Persian culture but then it changed to Google Farsi which is new name of Parsi (Persian language) after adopting Arabic alphabet by Persians.

Farsi vs. Parsi has tons of difference. People got mad and happy for this decision. I don't believe this kind of decision is made by design team.

Wall street in a nutshell. Brilliant.
I think someone's skewing the poll.

Personal wealth follows a powerlaw distribution, and there's good reason to believe that income from stock options is somewhat similar. If you look at the numbers above they make reasonably sense except for the "in the hundreds of millions" which is far too high compared to the others. The "in the hundreds" and "in the thousands" should be higher, but I'd wager that that can be explained by people not getting stock options in the hundred or thousand dollar range. The paper work alone would cost more. It's expected that there are a few, since a stock can tank, so stock options initially worth millions can turn into thousands when cashed in.
We have the police for that.

As far as I recall, these guys also confiscated all of the benefits from the exploit, although all of it was conducted on rather friendly terms. The team that had devised the scheme actually disclosed it to the game devs but the policy on loopholes was clear: even if you disclose, you don't get to keep the loot.

Sounds more like a poorly implemented game mechanic more than cleverness on the players part. They basically let their users set the price then distribute rewards based on that.
