Good job, y'all. Small, powerful, well connected, convenient to use. I think there's a chance you'll hit it out the ballpark. What you need now is shields, lots of shields, and libraries, lots of libraries. For Arduino there's a library for any sensor under the sun - you'll have to try and cover at least the most popular things out there.

You know what's missing from the site? As a long-time Arduino user, I've learned the value of knowing in advance, very clearly, the number of digital and analog inputs and outputs on any device I plan to use.

E.g., right now I'm wrestling an Arduino Mini, trying to fit all the digital pins I need for the OLED display, the tachometer sensors, the temperature and humidity sensor, and the various LEDs and control buses. It's probably gonna work, but it's a close race.

I'm sure that information is available somewhere for your device, it just didn't jump at me when I looked at the site. Maybe you should make it a bit more prominent.
Yeah, it's hyperbole. I could've imagined it, but I wouldn't have predicted that she'd ever start using that kind of tech. For the record, she's been using email forever. There used to be a huge gap between "using email" and "chatting online".
Probably much less DC power needed, too. Way less.

I made massive changes to my diet a few months ago, after being diagnosed with Type 2 Diabetes. The doctor said diet and exercise needed. Trying to keep it simple I didn't worry about the exercise, just changed the diet, the weight started falling off easily, as long as I ate regularly and kept my carbs to what was required.

I started riding to work this week. I am so god damn hungry right now.

I think if you are really needing weight loss you need your doctor involved. There is so much I have learned through having blood test results etc to work from.

My tips if you are interested:

* Cut out any added sugar. No sugar in coffee or whatever. Easy way to reduce energy intake. No more soft drink.
* Have enough carbs each meal so your body hormones etc are getting stuff to work with.
* Stay away from processed foods, keep out of those aisles.
* Make exercise a normal part of life and skip the gym. Gyms are demotivational hell holes of despair. Climb the stairs at work, ride the bike, park further away, just go for a walk around the block, walk randomly around the city to explore.
WHAT you eat can be as important or even more important as HOW MUCH you eat. 99% of people still don't get that, they think a calorie is a calorie.

We are not simply calorie burning machines. The human body, metabolism and related systems are incredibly more complex than that.
The ‘Too Rich to Succeed’ Challenge Facing Start-ups
We have two boys who are tri-lingual (thai, german, english). The essential thing is that the kid makes the association:

one person = one language

If you speak both English and Chinese to your son, he might be later confused on what words are from which language.

I would recommend you only speak Chinese to him. For our kids, English is now their strongest language but it was only taught by their 'environment' i.e. kindergarten / school and they started with English only at age 2-3. Now they talk English with each other (before they went through a period in which they talked German or Thai with each other). So you should not underestimate the 'environment language'.

Also, you might consider having some other relatives speaking certain specific languages with your son (e.g. grandparents). This could reinforce their language skills.

Personally, I do not believe that learning languages from TV is effective. Learning languages is about relationships and interaction. I think the 1 hr per day would be better spend on interacting with your son in the respective language, e.g. by playing memory game etc.

Regarding late development of speaking. We did not experience this with our kids. But they might be a bit delayed when learning to read and write because of different phonetic rules of the respective languages.

Ask HN: Best way for Google Calendar Notifications on Mac?
In January, Google discontinued its "Notifier" software for Mac/PC: http://googlesystem.blogspot.com/2014/01/no-more-google-notifier.html

Ever since then I've been wrestling with a variety of third-party apps and Chrome plugins without much success or consistency. They all seem to offer different behavior and levels of reliability... and I'm frustrated.

Is there any clear cut solution for either Chrome or Mac that's not bloatware and does reliable, synced notifications?

Mac would be better so that Chrome can be closed, but either works.

They make their money off the hardware though. And plenty of people use Apple hardware without using Apple services. I have an iPhone/iPad/Mac, and don't use Apple services for email/document/storage/photo backup etc. I appreciate their OS software and hardware, but for the most part think there are better options for pretty much all of their services.
Exactly. The real problem with fat gain/loss isn't sedentary vs. active lifestyles, it's calorie consumption. This is why smokers who never work out are usually extremely thin- they typically eat very little. That isn't of course to suggest that that is healthier than being a non-smoker who is overweight, but rather to show in an extreme case that for fat loss exercise is extremely overrated while simple calorie restriction is not given nearly enough attention.

The formula that I know works for me is calorie restriction and limiting carb/sugar intake as much as possible. This requires rethinking what is pretty much considered gospel in the U.S. Pretty much all breakfast foods other than eggs are just sugar and carbs and extremely fattening. Additionally, most meals in U.S. restaurants are about three times the size of what is actually needed to sufficiently sustain you until your next meal. If you want to lose weight and keep it off, increase your protein intake and cut your overall calorie and sugar intake.

> Are you a fan of the "benevolent dictator" ideal?

I'm not an authoritarian if that's what you're getting at - and this is getting way off topic...

> Do you agree with the NSA's redefinition of the word 'collect' to mean that something is only "collected" when a human see it?

I'm going to repost part of an older comment I wrote that addresses the issue:

This is the actual legal definition of 'collected' per DoDD 5240.1-R[1]:

"C2.2.1. Collection. Information shall be considered as "collected" only when it has been received for use by an employee of a DoD intelligence component in the course of his official duties. Thus, information volunteered to a DoD intelligence component by a cooperating source would be "collected" under this procedure when an employee of such component officially accepts, in some manner, such information for use within that component. Data acquired by electronic means is "collected" only when it has been processed into intelligible form."

That would include sent to the NSA, processed by algorithms and stored. The "read by a human definition" as far as I can tell comes from the EFF selectively quoting that definition[2] and drawing their own conclusions from their selective quotation, not the regulation itself. As the regulation itself states, as soon as any DoD intelligence components receives it and processes it, it is considered collected.

The misunderstanding is compounded by Clapper's June 9th 2013 interview with Andrea Mitchell, where he tries to explain that there's a legal difference between collecting content and metadata and fails miserably[3]. Mind you, Clapper is not part of the NSA. That's not an excuse, since as DNI he should know better, but it does explain it somewhat...

"by releasing most of the functionality of Office for free, Microsoft is giving up on the iPad as a growth driver for Office 365, but it seems like they can’t quite wean themselves of incremental income from Office diehards. The problem, though, is that not only could this limitation manifest itself as incremental annoyance, it also limits the defensive utility of this move (members-only)."

This paragraph stuck me as funny as it is decrying Microsoft upselling premium subscriber only features for Office 365 and then it ends on a link that is a "members only" upsell to a $10 a month subscription feature for this blog.

"Real speedups for you code!"
Yes, our primary method of making money will be through open source monetization strategies. I wrote thoughts on this here: http://notonlyluck.com/2014/01/16/monetizing-open-source-pro...

I bet the market conditions that led to this are broader than just GPU computing. I think it would more generally apply to any middleware business. But it is certainly more palatable for people in scientific computing and HPC to use something free and later pay for support and services and addons. Once people start really relying on the free thing, that reliance can be monetized. In this sense, it is more "scalable" to have an open source product which is readily adoptable by early users than to attempt to sell a product to buyers that have not yet started to rely upon it and have a good distance to go before reliance sets in. This is not SaaS and never will be, haha.

Allocation of future resources is something that we have considered a lot. I wrote before about opportunity costs associated with an open source business model: http://notonlyluck.com/2014/08/13/opportunity-costs-required...

We just open sourced today, but our plan is to treat the open source product the same as we have always treated it even when it was proprietary.

//Apple is a hardware company.

How is a company that makes OS X, iOS, iCloud services not a software company? Sure it sells hardware, but not hardware that's a brick.. People buy the hardware so they can use the software which pretty much means they sell a package that includes both hardware and software..
This looks amazing however $2800 price tag is way up there for all but real or may be semi-professionals. It can fly to almost 15,000 feet which is just amazing considering that's where private small plane airspace is. In other words, you no longer have to rent a plane or helicopter to get that cool aerial shot of New York's Center Park or SF's Golden Gate bridge. Flight time is 18 mins which is also slightly higher.

It would have been nicer if they had clear "follow me" feature. Even better would be one-touch pre-programmed flight pattern. I can imagine myself sitting on a summit of a hike or ski resort or beach and doing one-touch pre-programmed cinematic flight path to get that super-cool gimble stabilized video that makes a circle around me.
> Basically you just have to be vigilant with not eating too much.

No. There's no consistent evidence of large groups of people who started reducing calories and in return lost pounds predictably. Subjects lose energy, become irritable, get headaches and migraines, have hunger pangs, every now and then just fall off the wagon and over-indulge, or just plain simple gain weight on reduced calorie diet in a controlled experiment.

The book "Good Calories, Bad Calories" contains in-depth research on the topic http://en.wikipedia.org/wiki/Good_Calories,_Bad_Calories

> with low carbs, no sugar

Now you're onto something. Sugar and carbs stimulate insulin production, which then stimulates fat storage.
I think your comment shows part of the problem, which isn't mean as a dig.

carbs, sugar, low dairy, small portions? What does this leave you to eat? The average person will go crazy following these rules.

The problem is people aren't realistic about what they are eating and their activity level. It is okay to eat poptarts, icecream, whatever it is you like. But do so in moderation. It's not okay to develop a habit of gluttony while on the couch.
Ask HN: Equity Expectations for Founder Funded Startup?
I've been approached with an opportunity to work at a new startup. I've known the founders for several years, working with them at one point or another. They understand both the business and technology side and have had several successful exits.

This is all great, but because of this, they're self funding and not offering a lot of equity, but a pretty competitive salary (10% drop from my current mark which is on the high end in my location). My risk is essentially nil, and my upside will be nice if we're successful, but I'd like to have more skin in the game than the 2%, grant not option, they're offering at the start.

We've started doing some work and I'm making most of the technical decisions, developing our architecture plan, etc. This is my first time at the ground floor, like we don't have an office yet ground floor.

On the plus side the founders can fund us for a while, and if things go well we'd probably be able to skip several rounds of funding, leading to less dilution. But the downside is that since I'm not putting a few hundred grand into the pot I'm not a founder but merely a first employee.

With the realization that I'm taking the job, and enjoying the ride either way. Do you, HN, think that I have a shot at moving that percentage up, either through some incentives if I continue down the road of "CTO" for the company, or some other way? Or is this just part of the deal when working for something funded when the founders don't need to distribute risk?
Wow so many sick features... No wonder they haven't been picking up the customer service lines, or wait DJI customer service policy is simply not to reply. Never mind...

The product looks insane. Price point too.. Similar systems today cost 30K.

The problem with DJI is the generic firmware. I am still running old firmware because of all the crashes and complaints they have dramatically reduced performance / angle of attack, etc with each release.
Not really though. Microscopic compared to today.

Does not matter. When you buy an Apple product, you are basically supporting their services as well. And as far as I know, you are more or less forced to have an iTune account if you have an Apple device, right ? So you are tied in to their services at least for the distribution of applications (on mobiles).

> The formula that I know works for me is calorie restriction and limiting carb/sugar intake as much as possible.

The latter might be more effective than the former. Dr. Atkins adopters have challenged people to gain weight on the high fat / high protein diet, and those who took up the challenge simply could not "fatten up" - after a while they could consume only so much meat, cheese, fish and green veggies before feeling completely satiated. So there is a hard practical limit on number of calories consumed on a protein/fat diet.

Compare that to carbohydrate-related cravings, where people talk about having just another [calorie-laden] scone, cookie, or piece of candy, and seemingly losing track of consumption.

I'm surprise that he went about building the large-scale automated machine first, rather than evolving it from simpler devices. That the development was delayed and almost lost for good serves as a warning more than his success is an inspiration, I think.

How I Use Virtual Assistants for PR/SEO
Part of me is somewhat worried. Part of me recognizes that a 3D printed firearm is hardly very practical, consider it's easy enough to get a real firearm, even for convicted criminals. (I'm speaking of the US here.)

What keeps people in the US from going on shooting rampages is not the difficulty of getting guns. It's the fact that most people don't want to go on shooting rampages. And while I'd much prefer it if guns were banned in this country, in the end, I'm not planning to lose any sleep over it. I'm far more likely to die in a car accident, even without adjusting for risk factors like where I live or my lack of involvement in criminal activity. So if I want to worry about something, I'll focus on driving more carefully.

Anyway, there's precious little you can do to stop 3D printed firearms from eventually being available. Betting against progress is rarely safe, especially in this domain where it's pretty obvious how things are going to go.
