> If a bridge covers 50 square miles, it means that a device must cover 50 square miles to reach a bridge.

Range isn't determined by the minimum of the broadcaster and the receiver, its more like the product of the receiving antenna capacity (a function of size, mostly) and broadcast power. So any stated range has to be not just the coverage of the bridge, but the coverage of the bridge given a presumed device on the other end.
It's quite the hike. Covered in varying weather conditions. Not nearly as bad as either the heat of the deep south or the cold of the northeast, but rain or just the fog and humidity plus walk make for a damp experience.

Worse is trying to rush the distance catching one of the hourly-only off-peak trains. Or having to carry anything other than a light bag the distance.

This... is fortuitous I suppose, but my cofounder is actually the one who identified the vertical AND brought the first customer/partner. I was the execution guy who also happened to be a domain expert in a relevant field.

However, to get to this point: this was startup #3 for us together (and monetizeable side project #15~20, by this point in life). Our first startup fizzled out over time as the vertical became efficient (right domain though); our second was poorly executed and run (totally my fault)... but we grew together as a team. And on collective try #3 we learned through our fuckups to not do them again.

Tern works perfectly well with sweet.js. It uses loose parsing so it basically just ignores the areas that it can't understand.

For the most part, you still get all the info you used to have. Generally you don't use macros that are overly aggressive in modifying scope, or changing the basic rules of JS that tern looks for.

You will not get autocompleting on expressions that expand with macros, no. But you could easily add a plugin to tern that tells it the rules for that syntax if you really wanted to.
"Coffeescript inheritance semantics" aren't anything special in javascript. If the editor was written in javascript syntax and still chose to make use of inheritance in its design, extensions would look the same.

This works just fine, and it can't get much more javascripty:

ExtensionComponent.prototype = Object.create(Component.prototype);
function ExtensionComponent() {
Component.call(this);
}

ExtensionComponent.prototype.doSomething = function () {
// ...
};
Hey Sweis -

There's a whole process to how the secret for each device is created. That secret is used to ensure helium connectivity is safe. You can then securely implant your own secret into a chip we use and that secret can be used to encrypt your payload. Helium never has to know what you are sending. We just need to know where it's going so we can get it there for you.

We'll be posting more docs on this in the coming weeks and months. Feel free to shoot me an email if you want to chat more before they are available.
A bit OT but without knowing much about React it looks like you need to put your markup in your logic. What happened to the separation where the markup lives in its own template files? Seems like a big issue to me.
"The Helium Protocol uses a modified-802.15.4 frame for transport, and existing ZigBee deployments can be retrofitted to run Helium."

They are using something similar to 802.15.4 for at least their physical layer. If their power numbers are correct, then they are probably not using any of the specified 802.15.4 physical layers exactly to spec.
Year off of school vs. starting a company
Sorry if this is the wrong place to ask, but I figured I would find the best insight and expertise here. I am currently a sophomore at UC Berkeley in EECS. I have two more years of education to go until I graduate, as I will be getting my degree earlier.<p>I currently have been working for a small startup in San Francisco called XVolve. It has been a blast, I've learne d a lot and had fun being productive and getting more work experience. However, since my boss has been forced to go to Japan for three months, the project is on hold. This small startup is owned by a parent company in Japan, Onesty. They, through my boss, have offered to fund me to create a new company with me at the head and build a new product (likely a social app or something of the like) for them. I would get some equity, but that's not my concern. I am wary of this opportunity because I don't know why they would be dumping so much money into me, when I have no product, no team, and no background experience. They want me to take a trip to Japan (paid by them) to meet the executives and take a look at their company. They have no other well-known companies they've funded in their portfolio, I would be part of the first.<p>Any insight and perspective is greatly appreciated. It's difficult not to fantasize about the slim chance of success, but I need to keep my options realistic. My biggest fear is regretting that I didn't take this opportunity.
There are multiple problems with this, from both a regulatory and internal control perspective:

* Regarding testing internal changes - banks maintain vast test databases (admittedly full of customers called Ronald McDonald) covering almost every scenario. Testing goes far beyond unit testing and smoke testing, but dedicated teams of system integration and user acceptance testers. This 'test' was not a 'test' by any measure of internal policy.

* Contractors should not ordinarily have access to customer data. Regulators across jurisdictions make this clear. They can, but an excruciating approval process is necessary.

* Contractors having external email access to anything but whitelisted domains is unusual, and worth raising an eyebrow at.

* Why is the email address being typed in? I've never worked at Goldman but expect like almost every other bank in the world they use Exchange, which typically allows typing in [Lastname], [Firstname} with a list of people to then select (Jones, David1; Jones, David2; Jones, David3; etc).

* Why aren't attachments required to be encrypted, especially to external domains? This is an automated feature in Exchange.

I'm pretty familiar with all the duck tape that gets used in daily banking. So are regulators, who take a dim view of VBA being used as glue to tie together 1000s of internal systems, but often turn a blind eye. But this is not a case of duck tape, it is institutionalised failings at several levels. So the response is not surprising, Goldman have to show they take this seriously, despite so many internal failings, and shirk a bit off on 'external contractors' too.
You should seriously consider getting an SSD > 5400rpm drive, if you can afford it. It makes a massive difference.
If this company gets successful at all they may run into the AT&T effect of being a monopoly of a useful technology.

Their biggest strength is that they are the first ones in the field, their biggest weakness is that they own the tech, it's difficult for people to trust someone who owns the entirety of a market.
The only thing that makes sense to me is that given the same distance from the peer (the bridge in this case), it would consume less energy than BLE. They do claim, however, to accommodate longer ranges (by design) than BLE and I wonder if this holds true with no modification to the device itself (i.e. different RF blocks for short/long range).
Shuji case was a strange one, though justice was served at the end.

I'm a US citizen, and I dread going through immigration when returning to the US. I understand the psychological techniques they use to trip up people that are lying, but really? I have a valid US passport. What are you going to do, deport me? I'd love to see that.

(I've always wanted to get in a state where country A wants to deport me to country B, but country B wants to deport me to country A. I guess I always answer the questions right, though. "Did you come in contact with any soil on your trip?" "Oh no sir." "Welcome back.")
I'm not interested in SSD at this time :-) 5400rpm works well for what I need.

This is traditionally called "micro CHP". It has potential in places without district heating infrastructure, otherwise DH CHP is much more efficient.

These aren't really new. Eg here is an article looking at an existing commercial gas powered Stirling micro CHP that's quiet and designed for your house: http://www.f09.fh-koeln.de/imperia/md/content/personen/somme... - there's also a comparison to an ICE based equivalent and it has much better electricity generation efficiency.

The total efficiency is going to depend a lot on where you use it. The heating output is locked to the electrical output so you're always going to generate the 5 kW of heat per each kW of electricity, so you have to stop the plant when your hot water tank and house is heated up - or start throwing away all the heat and just run it as a low efficiency genset.

The large pool case sounds like a fit, but from another perspective it's just greenwashing the huge energy sink of the pool. The laundries & restaurants case sounds better here. Or regular houses in climates where a lot of heating is needed most of the year.
To be fair, you can put your paper on your own site with minimal modifications (an extended version with an extra sentence). Most people who care about their papers do this, but it is very annoying that the Digital Library is not a very effective resource, and that the ACM is stuck mostly in the past.
Even when the form was valid, it didn't work for me (checked in both Chrome and Firefox). I had to manually remove the `disabled` attribute on the submit button to post the form.
I wonder if I can convince the author of this to put it up in a Git repo so everyone can contribute. It probably needs the tiny URLs removed (IME, they're more likely to break than the original site)
My Canadian friends almost always get the third degree when they come back to the US with a TN visa. It's one you have to apply for at the border, but the folks at the border always seem to hate it. (Those damn Canadians stealing our jobs? I don't get it.) One friend got rejected (or hassled thoroughly, he's here after all) because he took too many English classes in college, and not enough engineering classes, so the TN visa appeared fraudulent.

I don't get it. If I ever move to another country I will only do so after paying very good lawyers to make a perfect application.
Moreover, if you really need a text editor for a log file, you can just launch vim or something for that task.

I've never really understood why people get in this mindset of "X is my editor, and I will only use X."

I guess, though, this is harder to do if you insist on a completely GUI-based interface.

Well, Tor is used ONLY for criminal activities. That's its entire point. You're in a state where talking to the Americans is a criminal activity punishable by beheading. So you use Tor to talk to them. I'm almost certain that activities which are criminal in the USA outnumber activities which are criminal in some oppressive regime on the Tor network. That's only because it's a damn good and secure network and we have less people standing against oppressive regimes than we have ones standing against USA law.

You can't have a really secure anonymous untraceable network, but also monitor everyone on it for illegal activity. The entire point of that network is illegal activity, for local definitions of illegal.
I hate to be a critic, but to me the remarkable thing with Google's Street View is how stagnant the interface has been. They have collected so much data, but using it is still so painful, really a last resort. It is impossibly slow to explore an area. Heaven forbid you click on the wrong side of an intersection and have to click a half dozen times to cross the street. There has to be a better way.

I am not sure how much they have rolled out, but Microsoft has been much more innovative in presenting Street-View-style imagery, e.g., using linear panoramas along a street instead of a series of spherical panoramas.
Do neither. Stay in school. If you leave, you'll never go back. (trust me, this happens 99% of the time when people leave school) You can take a year off after you graduate. And job opportunities come and go. This one certainly doesn't sound like you're getting in on the ground floor of something great.
13 Valuable Lessons From Failed Startups
Hey Amscanne -

There are two things we're trying to convey here (but rest-assured we're not trying to be misleading):

1. We can support a lot of connections. I mean a lot. This is based on our design, but truly limited by the receiving radio.

2. 50 square miles is optimal conditions. It's hard to quantify how bridges and radio enabled devices will work in populated metropolitan areas. These numbers are solely based on field testing, not in metro areas.

You're getting downvoted because you're insensitive. Yes, it's true that there are immigrant-intent visas and non-immigrant-intent visas. There are fewer people who get the right one, and even fewer people who really know what they want. Maybe they come to the US on a TN visa and think, "hey, I like this place, I think I want to live here". Now they're an illegal alien based on your definition. Similarly, there are people that get immigrant intent visas and don't like the country all that much, and never bother to apply for permanent residency. Both are fine and reasonable decisions. If there weren't fixed numbers of visas, people might make the right choice, but since there are, they decide "I'll get in and sort it out later." (Hint: get a lawyer if this is you. It can be sorted out, but it isn't trivial.)

Anyway, as an American, I don't really see the point of restricting entry to the country. Nobody is going to steal our jobs. Incoming criminals are going to have quite a bit of trouble with the local criminals, which are quite numerous. It will all work itself out.

It's not like there's free medicine or food given out to everyone in the country, so if you're here, you're own your own. The government will send a fire truck to put out a fire in your home, and we have some roads. That's it for government assistance.

Anyway </rant>. Come steal my job.

>>> they would be in the clear, legally speaking, to publish those photos of you smoking a joint at 18.

So what? We know three of the last US presidents used drugs when they were young. For none of them it was a major problem. If they had seriously bad things done in the past - that would be a problem, but the we want to know about it. Knowing that the presidential candidate smoked weed in college doesn't hurt him anymore - we already know pretty much everybody did it anyway.

>>> This analysis would suggest that free speech and privacy have a very fundamental conflict

Only if you define privacy as "ability to go back in time and undo public things that I did". In my book, privacy doesn't mean that. 1984's memory holes are not privacy, they are an instrument of oppression and mind control. I don't see why somebody would be allowed to control my mind and make me forget things about them that they no longer consider beneficial to them. So I know which side I would choose - the opposite of where 1984 is and where EU is heading now.

I just finished grad school and undergrad right before that (I lumped them together in 4 years; not to brag, this matters for what I'm about to say). I spent most of undergrad tempted by a few nibbles to take a gap semester or year and see what happens. The way I see it (and others on here may disagree with me), you should stay in school unless the golden opportunity comes along. Here's why: you are earning your education at one of the top schools in the world for EECS. You, provided you don't screw up, will have any number of opportunities post-graduation that others won't have, especially when it comes to startups. I graduated in 5 semesters from undergrad because I wanted to 1) go deeper into a technical background (undergrad in information systems / business - yes, I'm from "the dark side") during grad school
2) work for a startup

I chose to go to grad school, and along the way wound up working for a healthcare informatics startup. Great team, I trusted them a lot, even when they had a major product pivot. Last fall, I had to make the choice, wait for a spring offer to join them full time (yes, please and thank you) and reject other fall offers, or "play it safe." I took the handshake agreement and it wound up falling through. Am I pissed? Yes. Am I glad it happened? Well, I got a great learning lesson out of it, and am now doing my own startup in data analytics, commercializing a side project I did during grad school.

What I'm trying to get at is that yes, you will always regret the "what ifs?" However, be rational about the team, the product, and the vision, and the opportunity cost of putting your education on hold. Yes, you can always go back, but I've had friends do it, and it is hard(er). I'm happy to talk more about this or follow-up, since I know from semi-first-hand experience a bit of what you're going through. You have a lot of options on the table, but just look long-term and be true to yourself, more than anything else.
The key here is the majority of the content on your Facebook feed is what your friends and family post. Your friends and family's posts have massive meaning to your life, and you will take on board their sentiment more than, say, an ad.

The meaning behind the music in a supermarket is negligible - you don't give any weight to songs played in a supermarket other than "I like this song" or "this song is annoying".

In a sense this whole fiasco is a good thing. The feed, for me, has now become less attractive as a "news source" for what my mates are up to. And that can only be a good thing. I dislike how much everyone (including myself) has taken to Facebook as a means of friends/family communication.
When I Read the title I thought of the Google and Apple wage fixing case, and I thought... the ACM really isn't representing the professional programmer much. Not in the same way that the AMA, Bar association or many other professional associations do.

Some might say, well that's not what the ACM is for. Why not? Continuing education is great, although frankly being a journal publisher isnt 'education' to me. But if the ACM wants to really expand, they need to think about what the working programmer really needs.

If the answer to all this is 'keep publishing stuff' then maybe the ACM is just an academic bridge, and these articles about being for the 'professional programmer' should just stop.

LOL I've flown as much as 250k miles in one year. My number one goal is to make sure I get on the "destination" sleep pattern as quickly as possible. I set my clock to the destination time as soon as I board the plane, force myself to sleep on that schedule and I open the windows in the Hotel to make sure the sun wakes me up. I do feel the sun is a big part of the process. Most people who travel with me find it frustrating how quickly I adjust to new time zones. I always give them the same advice.. Follow the Sun.. Live by the Sun.. Sleep when it goes down..

To simplify: Bitcoin miners race to discover a code that gives them 50 bitcoins. This code gets harder to find each time it is found. This decision is pre-baked in using the bitcoin system (other e-currencies have different traits.)

If you join a mining pool then you split the 50 coins with everyone else in the pool (and they'll split with you) if you are the lucky machine than found the code.

The analogy is pretty direct: mining is the same as going and doing work to dig up gold, buying from the market is the same as buying gold in the market.

Most wireless access methods either have low range or low transmission rates or high power usage because of physics, not because of regulation.

Eg, BTLE optimises low power at the expense of range and transmission rate. It sounds like this is optimised for low power, low transmission rates. There isn't really another widely available protocol optimised for that (except ZigBee).

That's a very useful option - devices like FitBits and Garmin bike computers use all kind of work arounds involving teathering etc to try to make connected systems small and still connected.

Living authors can put their paper online, yes. But what about all the older articles from authors that are already dead, to which the copyright is now owned by some corporation? That's one of the worst things in the current copyright system.
In an actual legal case it is your right to be told exactly what you are charged with. Universal is taking actions based on copyright law but outside the legal system and refusing to be specific. This is allowed behavior but it is extremely distasteful.

It is not acceptable to mistreat someone because they are doing 'something' wrong.
