>I don’t know how Hamilton Beach did it, and I’m exceedingly curious as to how. The people at Steepster don’t think too highly of it though, so there’s some clues there.

In regards to the $45 variable temperature kettle. The folks at steepster probably didn't care for it because the temperature range is pretty narrow. For high-quality tea, 175-212F simply isn't a wide enough range. It's also not very precise. Many delicate green teas are best prepared at temperatures as low as 140F and in some cases just a few degrees can make a difference.

I've wanted a Zojirushi for a few months now. Heard really good things but also heard about the build up of scaling after some usage(I guess that depends on the type of water you use). I only drink black tea (using teabags - nothing fancy) so spending north of $100 seems overkill.

"Jobs would probably have died homeless and friendless if Apple never existed." - so funny.

Besides Apple, Pixar and Next made Jobs billionaire too. So, no jobs would not have died homeless and friendless :-) . Jobs was a natural leader and visionary.

I wouldn't hold Allen up as an example of reinvention as his "renaissance" activities now include patent trolling. And Woz is none too happy about that:

This works for you because you live in a society where a significant majority of people are trying to be nice towards other people. Because you choose to ignore the social contract of "let's all try to be nice" you can circumvent the drawbacks of that agreement. If everyone actively pursued your approach, however, we'd be in a mess. Also if you encounter another asshole, it becomes survival of the fittest. And again because you live in a "nice" society chances are the other asshole doesn't have a lot of experience at being an asshole. But sooner or later you come across a colder and smarter son of a bitch than you.

I don't know about bacteria, but a banana variety is all essentially the same plant, propagated from a central stock. Have a look at the controls around planting and growing your own bananas, it's all red tape, permits and extremely fascist:

http://www.backyardbananas.com.au/faq.html

http://www.daff.qld.gov.au/plants/fruit-and-vegetables/fruit...

And for very good reason: every banana of a variety is susceptible to (eg.) a virus outbreak - there won't be any pockets of genetic variability like you would get with potatoes or citrus. If anything that affects bananas becomes widespread - no more bananas.
Bought a kettle today, £12.

I guess in the UK they are counted as a necessity and are cheap :P
Other people have given you this advice already: Play around with an arduino for a while until you get comfortable with the hardware/software interface. If you're looking to incorporate sensors, get a few breakout boards from sparkfun (doesn't really matter what sensors) - one that you read as a voltage level from the ADC (analog to digital converter), and one that uses I2C, SPI, or another serial interface.

On the Bluetooth LE side, you CAN get a shield that sits on top of your Arduino, but it'll be bulky and power hungry. There's a company called Bluegiga that makes a BLE stack called the BLE112. Basically, it's an arduino and a BLE module in a package the size of a postage stamp. Not something you'd want to go into production with (doesn't get much below $15, regardless of quantity), but you can run it off of a coin cell battery for years, and it's got all the serial and analog interfaces you'd expect. You can get a breakout board for around $50 assembled - google 'ble112 breakout inmojo'.

Good luck! Build cool stuff.
While I think the book was worth the read, I think Isaacson was wrong on so many small and big things and failed to go into others, and he really did a poor job with the book.

pikachu_is_cool points the finger at something which doesn't receive nearly enough attention in the tech circles on the US West Coast: Chasing work, marketable skills, money and "success" at the detriment of everything else: Work-life balance, healthy relationships, enjoyable hobbies and overall quality of life. People are obviously free to do whatever they want with their lives, but from my perspective the status quo in the Silicon Valley startup culture is very destructive for the mental health and overall long-term happiness of its members.

Whenever I read a story on HN about 55-100 hour workweeks and lots of comments making this seem like something which is sane and healthy, only taking vacations when you are between jobs, being a serial entrepeneur chasing failed venture after failed venture with the hope of eventually striking it rich, prioritizing personal relationships and interaction with friends behind your company's interests and relentlessly using any (rare) spare time to work on your "startup" or learn skills other people will pay you money for, I cringe. I will never take a regular job in an environment like this. It would fuck up my mental health in less than a year, and I am very surprised that others don't see this. I can only describe it as a collective blindness for some very important parts of life.

There is certainly plenty of opportunity in one of the biggest tech booms in world history. But it's not opportunity that comes without a big human cost, and this side of the story doesn't receive nearly enough attention. When work and success is lauded as the virtues above all, other valuable things will suffer. Most people aren't cut out for this kind of lifestyle, and there is nothing wrong with that.
I've only had problems with videos loading - not the front page - but that's been happening all day today.
For me the perfect kettle is a simple glass kettle because I've found that it doesn't change the taste of water whereas metal or plastic kettles do. Also, I don't like the idea of heated plastic compounds leaching into my water.

Bonus, it looks cool to see the water start to form bubbles and then to go into a full on boil!

I was replying specifically to "since bananas are clones, there's nothing for the selection pressure to act on." That's not correct reasoning, since the DNA in plant clones can mutate, and thus, plant clones are susceptible to selection pressure.
you're paying for the alessi name and design (Italian)
If you want to know why, the only way is to ask them.

This is BSD, so the authors want companies to be able to keep the modifications and drivers proprietary if they choose to do so. So in this case, its very much possible that the when is "never" and why is "money".
Hey, I can relate. I'm betting you grew up under really traditional foreign parents who raised you in a very high-pressure, high-stress environment that only offered support if you followed the rules and fulfilled the expectations. I did. And I totally agree with your last sentence.

My advice is to start figuring out what it is you want to do and sketch a plan to get to that place. If your parents/community are anything like mine, you'll get a lot of hate and no support, but pushing through it is worth it. Find what you enjoy now because you don't want to find yourself 10 years from now deeply regretting the fact that you followed the mold and did what everyone expected of you.

You won't be a failure if you pursue a different path. Don't believe that because it'll paralyze you. And if you don't get a 2400 and don't get into UC Berkeley, what's the worst that'll happen? Chances are you won't become homeless.
If so, such an elegant solution. So elegant.
> > just restrict the use of macros

> Precisely.

Enabling macros is the sole justification for the homoiconic syntax, which is often cited as the most offputting feature of lisps for uptake by large programmer teams. If you're going to have two "editions" of Clojure, one with the full feature set for language designers, and the other a more restricted sans-defmacro one for more general programmer use, then why not give that restricted one a more friendly syntax as well, or even just get them to use Java, Python, or whatever.
The quick answer is supply chain markup. Stuff isn't sold at cost because that's usually not a winning, sustainable strategy. Distributors (if there are any), manufacturers, and retailers will all want to cover their (varying) overheads as well as make a profit. The largest profit is generally made by the the retailer. A bricks and mortar store has markups of about 100%.

All the above is why you sometimes hear people talking about shorting their supply chains because it means lower trade prices, which in turn allows for increased profits, an increased ability to compete on price, or both.
You're generally right about `sans-serif` vs. Arial/Helvetica. There used to be a complication in that even on OS X, Arial has significantly more glyphs than Helvetica but as browsers get better font substitution support and stop breaking ligatures (http://chris.improbable.org/experiments/browser/combining-ha...) this matters less.

It would, of course, also be significantly less important if they optimized the download decision so you could use something like noto for everything and not have to worry about significant visual differences.

I didn't say nobody on welfare is smart, I said "in general". The OP posted a macroeconomic proposal, which is built upon "in generals". Read the Bell curve for all kinds of IQ related studies.
As always, there's an old and insightful pg essay on these economics: http://www.paulgraham.com/wealth.html

The trivial conclusion is that starting your own company is how to be accurately rewarded for your work. But that assumes there's no way to better measure employee performance. It seems like measuring it for engineers and programmers is an impossibly hard problem (At least, that's implied from all of the well-run organizations that have given up or failed miserably on quantizing performance over the years.). However, I would like to see some creative attempts at making teams better at this.

While interesting, I think these diagrams are dangerous. They send a message that if fresh fruits contain these "scary" chemicals, then we shouldn't worry about the chemicals we see in processed foods. The problem is that some processed foods really do contain chemicals we should be afraid of. Artificial colours or things like calcium disodium EDTA are good examples.

My part time project has been to try and provide some simple to understand descriptions of the "scary" chemicals at http://foodconstrued.com
"In general" is good for macroeconomic proposals - I'm saying if you give money to all smart kids, it would end up on average transferring money to higher income families.
Bitcoin carries all the risk of cash and more; a bitcoin mugger would be able to get your life's savings rather than just what you have in your wallet.

Yes. In a world of dodgy software patents, it's pleasing to see good 'real' patents.
1) I genuinely prefer variadic prefix notation, even in the absence of homoiconicity.

2) Restricted does not mean "banned". It means that they need to be justified and subject to expert scrutiny.

3) Even if you never write a macro of your own, you're a beneficiary of the syntactic sugar and can leverage macroexpand to demystify otherwise opaque language constructs.
> ...for those kids it can be a living hell...

I think you need to check your privilege here. You grew up in a household with successful parents that wanted their children to succeed. If you didn't get into Berkeley, you'd have your parents be disappointed in you. The main economic driver in your area wasn't something you were interested in, so you'd likely have to move when you grew up.

I would go so far as to say that most people in the US (not even the rest of the world) have childhoods that better resemble a living hell. I suppose most tragedy is relative, and I'm not trying to delve into Candide-style one-upping. I'm just saying that maybe it's not Silicon Valley that sucks, maybe it's just growing up.

How are you liking Racket instead of Rails? I'm assuming you're using it for web development.

I was a Rails dev that moved to Clojure and I don't know much about Racket at all, but how is the library situation? Of course in Clojure if I ever need something I can count on being able to find it in Java and interop with it.
>Besides Apple, Pixar and Next made Jobs billionaire too.

If Apple had never existed, he wouldn't have had the hundreds of millions dollars that he spent on these endeavors.

>Jobs was a natural leader and visionary.

Jobs was good at recognizing when the right time to bet on a technology was. When you are filthy rich, you can turn this talent into a license to print money. When you aren't already rich, it just makes you the average person on HN.

I can predict the success and failure of specific technologies with a staggering degree of accuracy, and I'm sure that most of the techies here can do the same thing.

Was anyone here surprised that RIM's brushing off of the capacitive touch-screen launched them into a death-spiral?

Was anyone here doubting that moore's law, flash memory, and high-resolution touch-screens would eventually make it possible to create a tablet that consumers would actually want?

Was anyone surprised that Android overtook a platform that was designed from the ground-up to serve as a symbol for exclusivity? Guess what happens when you launch with only one of the four major carriers? You just gave up any advantage you gained from being first to market.

This shit is obvious to people who live for technology. Steve Jobs didn't create the iPhone or the iPad, the electrical and computer engineers who saw it coming a few decades ago did. They saw potential and so they spent the best years of their lives developing the technology that would one day make it possible.

I'm not saying that Steve wasn't talented, because he was. I'm just saying that it takes more than talent, intelligence, and leadership ability to succeed at the level he did. There's a random element to it, and this random element is the largest factor.

There are thousands upon thousands of talented, smart people with ideas that could change the world. Most of them, if they ever even get a chance to try, will end up being crushed by a world that is reluctant to change.
I challenge you to a blind trial. I very much suspect that using an electric kettle and a glass kettle you would not be able to taste the difference of the water once cooled. (We'll run the electric kettle twice with clean water followed by a flush, as most manuals state.
With no definition for "Not natural", you render the word "Natural" essentially meaningless- turning it into a "valid" adjective encompassing everything.

Which, for reasons that should be obvious, makes it problematic as a word for promoting certain types of food. Since humans are components of the ecosystem, twinkies are technically "natural", right?

Mastercoin appears to have a working market, transaction explorer, and reportable capitalization (at coinmarketcap.com), so it seems your information out of date.

you really dont see the analogy?
In theory, yes - but mutation rates of clones are going to be very, very low. Bananas are also grown from a central stock to control disease, so even if there were a mutation, all the bananas are going to mutate identically.

Bacteria reproduce in all sorts of bizarre ways, including swapping DNA from other bacteria, editing their DNA, etc., so it's not really related.
If you set up 10 Digital Ocean accounts ($50 / month) and mined some scrypt-based coin (optimized for CPU mining) and pointed all ten at a pool, that's only ~30khash/s. Your desktop PC probably has more than 30khash/s mining potential. D.O. is one of the few hosts that doesn't block mining and we'll see if that lasts. So 30khash/s is maybe 20 cents worth of altcoins/day minus fees to convert that into dollars. So you're already losing $44/month, hurting everyone on your hypervisor and difficulty is rising. And I think Litecoin was an attempt to make CPU mining more lucrative ;-)
It does, any changes?
> Here's our prediction: By 2035, there will be almost no poor countries left in the world. Yes, a few unhappy countries will be held back by war, political realities (such as North Korea) or geography (such as landlocked states in central Africa). But every country in South America, Asia and Central America (except perhaps Haiti) and most in coastal Africa will have become middle-income nations. More than 70% of countries will have a higher per-person income than China does today.

Woah - I would love to see some data visualization of this. If that's true - that's really, really something.
You left out poor white people in your discussion. While white people do have a lower rate of poverty than blacks or latinos, they actually make up a very large majority (68.5% as of 2009) of the people living under the poverty line in the United States. [1]

"... let's not pretend that the Cherokee are the ones we're worried about here."

"Successfully repeating this experiment in poor black and latino populations a few times would go a long ways towards convincing the skeptical... "

I'm all in favor of repeating the experiment in whatever populations, ideally the general one on a large enough sample size to tease out demographic information. I don't want to seem like I'm implying something here, so I will instead say overtly that I find the way you've singled out certain populations for skepticism with regards to whether they should be helped disturbing.

>>>>> xcept that the plurality of U.S. charity goes to religious charities.

Who actually do quite a bit of good with it:

"We should start by noting that Catholic charity work is extensive and widely considered a crucial part of the nation’s social safety net. By itself, Catholic Charities USA, has more than 2,500 local agencies that serve 10 million people annually, said Mary L. Gautier, a senior research associate at the Center for Applied Research in the Apostolate, an institute at Georgetown University that studies the church."

"Meanwhile, Catholic News Service has noted a few other Catholic organizations that made the Chronicle’s annual 400 list, including Father Flanagan Boys Home and Covenant House. This excludes Catholic universities, which mainly provide higher education; hospitals, which are categorized separately from social services; and groups that focus on overseas work."

source: http://www.politifact.com/truth-o-meter/statements/2013/mar/...

Considering they put out close to 4 billion every year in charity, it's hard to argue they don't help the impoverished.
Absolutely the case.
I found that pretty hilarious too. "Stop working to get rich, money is evil! Oh, by the way, give me your money."
The short version is that Siracusa recommends "Infinite Loop" by Michael Malone as the best single source for Apple history prior to the return of Jobs, and he says that the post-return material in the Isaacson book (ie, everything unique that it offers) is poor and/or limited.
The Tiva C Launchpad is about ten bucks and there's a course starting on EdX next week that uses it.

It's not an MSP430 (it's an ARM Cortex), but still it's great that TI pumps out these low cost boards for newbie electrical engineers.

When to start charging
Hi
I was wondering when is it the right time to start charging for what your startup is selling. I'm particularly interested on startups that are based on a B2B model. Should I start selling right the second I have something working or should I give it for free the first months?
