Groupon Launches Its Own Food Delivery Business, Groupon to Go
How does the 'new user announcement' chord work? And pitching in general?

The new user announcement seems to be on a 7th (always attractive for a short amount of time - mainly minor but not always - I've listened for a short amount of time). The deletes seem to be biased towards a minor chord.

I might have mixed that all up, but the chord seems to show some dependency.

Or it is just late a night.
Migrating from MySQL to MariaDB with Zero Downtime
I worked with a team of these before. You can rule our certain types of people with tech questions (i.e. never coded before, only coded hacked, etc.). You cannot rule out

* People who read a lot of blogs so know the lingo, but never code

* People who get the theory but can't actually implement something that works without bugs

* People that over-engineer simple things
I agree that just having the capital alone is not enough reason to start a business.

I was asking more along the lines of, "what controversial/high risk business have you always wanted to start, but that requires a lot of starting capital?"

(Purely software startups probably don't fall into that category)

Patent "troll" is usually someone who registers a patent for something completely obvious and already used by anyone in the industry.

Angry Birds back in a sequel to save game maker Rovio
Hi HN,

One of the guys who built Amplify here. We posted on Product Hunt yesterday, so some of you might have seen us there, but for those that haven't, some background:

Amplify is something that we've had in the back of our heads for a while. We built a hack version of it for our own launches, and when we told other founders, marketers, and product people about it, we got lots of "huh... yeah that's awesome... can I use it?" type responses.

While there are other services out there like that allow "group social scheduling" like Thunderclap & GaggleAmp, Amplify differentiates itself in that it focuses on the product/customer relationship.

We've had success internally with a previous version of Amplify, and now we're happy to offer it to the world.

Let me know if you have any questions!
I prefer it this way. When you changed your TV channel to MTV, there was no play button.
Yep, I actually just learned that a minute ago. Thanks for the tip. :)
It never is. That's why all camp stoves come with a warning not to cook in enclosed spaces. Just a few weeks ago I was out camping and a father/son duo died in their tent because it was raining out and they wanted to use the stove to warm up food.
I suppose that just displaying a page and scrolling around it consumes little energy, with a short spike during the layout phase.

What really consumes energy is compiling and executing Javascript, and playing animations (flash, gif, css, video). JS engines of all three browsers are likely different. I also suspect that Safari, being essentially single-platform, can afford platform-specific optimizations (e.g cheaper non-public API calls).
10 Eye Catching Startups from the MassChallenge Showcase
Agreed. 'Stop At Nothing' [1] documentary captures this and more in a gripping fashion. It's available on Netflix and a must watch if you want to understand the whole Armstrong saga.

[1] http://www.imdb.com/title/tt3511812/
It's worth noting what Steve Jobs said at the introduction of the iPhone:

"The full Safari engine is inside of iPhone. And so, you can write amazing Web 2.0 and Ajax apps that look exactly and behave exactly like apps on the iPhone. And these apps can integrate perfectly with iPhone services. They can make a call, they can send an email, they can look up a location on Google Maps.

And guess what? There’s no SDK that you need! You’ve got everything you need if you know how to write apps using the most modern web standards to write amazing apps for the iPhone today. So developers, we think we’ve got a very sweet story for you. You can begin building your iPhone apps today."

There was no SDK initially. Webapps were the _only_ way to put your app on the iPhone. My understanding is that developers demanded an SDK, though.

It seems that part of the reason for not wanting native Apps is because Jobs felt that policing an app store would be too difficult. As to whether the current browser is purposely crippled for the sake of directing people to native apps, I think that might be a bit difficult to prove. Is it perhaps instead that native apps naturally provide better performance, developers demanded it, and so Apple focuses its resources there? Shrug.

Some more detail here: http://www.cultofmac.com/125180/steve-jobs-was-originally-de...
Friendly speaking, we didn't make a performance or optimization research yet. I can only share an experience we've got from using taucharts in our main product - "Targetprocess".
So we setup a limit to 1000 rows (+/-50%) which seems to be acceptable performance / usefulness balance to draw a chart within a 0.5 seconds.
Also it depends on chart type. Drawing huge facet with more than 100 cells in it can be painful while plain scatter plot on the same data works fine.
I believe so yes.

I would have no problem subscribing to a company that provides access to TV shows, movies etc.

I think it really depends on climate but overall it's more insulated, sturdy, overall better just to do a stick built 2x6 structure the same size.

It really should be a browser level setting where you whitelist the sites that are allowed to do it. I don't mind when Youtube does it, but most sites annoy me.
> These are the people who don't know any better, arguing out of ignorance, not from some valid ground.

That's very unfair. Let's take Lisp-style macros. There are good arguments against macros in programming languages. For example, keeping the amount of primitives small and core language simple. I don't agree with these arguments (I am pro-macros), but it's not just ignorance.

> I do not see any extensibility features in Python, none at all.

Not sure what you mean, but macros are not the only way to extend a programming language.

One particularly common method is called "functions" (if you have ever coded in assembler, you will know what luxury that is). Then you have classes, operator overloading, metaclasses, decorators, native C interface, AST parser in the standard library..

Not sure what more, aside from macros, you could want regarding extensibility. Python is more extensible than C and Java, which are the most common programming languages in use.
Gallium-Arsenisde has a high switching speed because of the higher carrier mobility, but the higher frequency applications it is used in dissipate high power.

This article's transistors will not likely have a high switching speed, just high enough for switching power converters (100kHZ-few MHZ). The important feature of GaN according to the article is that you generate 1/10 the waste heat from current just flowing through the switch.

Power transistors don't perfectly 'turn on' like an ideal switch. They have a resistance to the switched path on the order of milliohms called Rds (resistance source to drain). And, heat dissipated from that is ~ I^2 x Rds.
I guess you found the math combined with the search for alternative routes interesting? But did you also try to find prior art? My first thought would be that for unreasonably broad patents prior art is the easiest way to be able to use the tech?

Dixie: turning chaos to your advantage
I mean, a bad hire is going to cost me thousands of dollars - if not tens of thousands of dollars. $500 is pretty cheap to figure that out up front on a candidate I am otherwise ready to hire. I am not going to do this to 100 people and pick the best, I am going to do it for someone that in every other way is a good to hire dev.

I don't think I would give out the same work to multiple people, let them put it into production on their first day and get the pride going ;)

Those are pretty good arguments you can use to convince your boss to start using your calendar software! So why hasn't he switched? I see some possibilities:

- No-one has pointed out these shortcomings to your boss.

- You have, but he is stubborn and refuses to see the downsides even though they are obvious to everyone else.

- You have, but you're overstating the downsides and the current setup actually works well enough as it is.
It's FUD because you're citing a worst-case scenario. I'll acknowledge that a drone is more likely to crash in a dangerous fashion (from a fire perspective), but it's still insignificant compared to the real risk that we live with every day from automobiles.

What's your view on the patent? Pretty broad? Or a sign of very quick progress that in 10 yrs something innovative (hence, a patent) turns into a few open source libraries and few lines of code to replicate. Most responses (including my thought) call 'patent troll' etc, but perhaps there was substantial thought and effort in the techniques below the patent.
Which is the exact situation I found myself in: I began developing in this area, and learned of patents I needed to sidestep. Realizing a hole in the patent landscape, I filed to protect what I was doing.

Still a false dichotomy. Everything we do runs the gamut from autonomous to executive. For instance, a relatively illiterate person will have to focus purposefully in order to read a street sign, whereas your average literate person will look at a street sign while holding 7 other things in his mind at the same time.

> Just as an aside, I would actually be more willing to undertake this type of interview if you weren't paying me.

Sure, and I don't think I would force pay you. Would offer you the in person option, or the homework option without pay. Could maybe work it into a signing bonus if you took the job or something? Definitely not looking to put someone into an ethical dilemma, but not wanting to be one of those companies who makes candidates do really long take home interviews and then makes them mad when they don't extend an offer.
There was also the fact that silicon was already heavily entrenched in the industry by the time people started to tinker with the possibilities of GaAs seriously. At least that's what I understood to be the main factor after listening to Seymour Cray's talk which was posted here some time ago:
https://www.youtube.com/watch?v=xW7j2ipE2Ck
He talks about how difficult it was to convince large suppliers to work with GaAs at about 30 minutes into the talk.
Interesting. This reminds me of the System 1 vs. System 2 thinking described in Thinking, Fast and Slow:

Or, what if I learn to touch type?
> Let's take Lisp-style macros. There are good arguments against macros in programming languages. For example, keeping the amount of primitives small and core language simple.

Wait, that's the argument for including Lisp-style macros as a primitive feature of the language: by doing that, you reduce the number of primitives needed, keeping the number of primitives small and the core language simple.

With macros, you can have fewer primitive control structures in the core language, and build other control structures that are desired on top of the existing ones + macros.

So, while there may be arguments for keeping macros out of programming langauges, the one you've presented is, instead, pretty much the main argument for having Lisp-style macros.
Isn't there a way to produce synthetic caffeine?

That is a good option too. Either defer it to a signing bonus or a charity of their choice.

Currently taucharts supports scatter, bar (vertical / horizontal), stacked bar (vertical / horizontal), line. Also in beta we have geomap charts with customized map and parallel coordinates. There is a lack of documentation.. but we are working on this problem.
Ah, I skipped down to "Testing Philosophy" out of habit when looking at benchmarks. It still doesn't say if the computer is rebooted fresh after each test, but I'd like give the benefit of the doubt on more obvious things like that.
Given that you called them facets, I'm going to assume you're familiar with ggplot2. In retrospect, I thinking adding non-Cartesian coordinate systems was a mistake. They are a huge amount of work and only make a handful of charts easier (and most of which, like the radar chart, are not that useful).
The current issue is because light is line-of-sight. Such systems traditionally need a lanyard of some kind to provide unobstructed access, and this is super inconvenient for the user.

Then there's the problem of means-of-detection; Phillips had a cool setup that relied on the rolling shutter of phone cameras; but as soon as someone comes up with a global shutter for phones, such systems are toast.

I'm sitting here writing this from a conference about the genetic disease one of my children has. He's lucky... he's of above average intelligence even on a normal scale. Many of his fellow disease sufferers are confined to a wheelchair, unable to speak even in their teens, and literally the only motions they make on their own is some vague twitching motions.

Yes, there is a such thing as true, uncompensated disability, and you should thank your lucky stars that you live a life where you could even entertain the notion that there is no such thing as "disabilities". Tone note: I mean that straight, not angry or something... be thankful. It's a hard thing for all involved.

Pragmatism is an ideology, not the rejection of any ideology. (Perhaps more generally, pragmatism is an umbrella name for a class of ideologies which are all about maximizing some objective utility function, they differ in what utility function they are maximizing.)
True but I am not hiring a freelancer. I don't think anyone spent a few hours interviewing to try and make $500 off me.

If you get to the paid homework step, we are ready to hire you, pending successful homework.

Ethereum Launches
Modern supercomputers are essentially clusters, but with much more advanced network topologies and technologies, shared storage, etc. It's not just one monolothic machine.

However, the types of computation performed by the top supercomputers are rarely the "embarassingly parallel" programs you can easily distribute via an @Home-style program, or something like Hadoop. They do depend heavily on very reliable, very low latency, high bandwidth networks.
I did a few minutes of research into this. The app banners are triggered by a meta tag, so there won't be a way to block those.
But is that really an ad? If I go to CNN, and CNN tells me I can use the same site in a native app, I'm not sure that quite counts. Now if CNN carries (for a fee) a download link for an app for something different, a brokerage house, or Ford, or something, now that would be interesting to see if they block it.

My guess is that they would initially, then relax the blocking. Seems to be the preferred way to manipulate the populace these days (unless you have fear as a tool- fear is way better).
This was my thought as well, take home tests are a good test of your skills, but super annoying when you already have a job + family + hobbies.
For tests 7 and 8, what if the Javascript was stored in an external file, which of course is generally best practice? For 7, would the string still be parsed and indexed? For 8, would the file be downloaded and indexed? I'd be surprised!

This inversion seems likely to be the way it goes. Networks buying content (TV model), rather than publishers buying ads (newspaper model).

My understanding is that the original C toolchain in Go (only recently removed in 1.5) was based heavily on the Plan 9 compilers.

In fact there was a rather inflammatory blog post[1] whose basic theme was that "Golang is trash" because the toolchain was so simple. One of the main Go developers then responded[2] on HN. Different people value different things I suppose.

The majority of these "Personalized Media" patents rely on existing integrated media - meaning imagery and audio composed of multiple elements - and the ability to isolate one element, remove or modify it, and/or replace it with something else in a manner that the original media's intent and message is retained, only now it is enhanced for a specific audience.

Think product placements that change for every single viewer.

Real time rendering, VR/AR and that entire enchilada of media techniques completely sidestep these patents because there is no original media, it's all created and composited on the fly, dynamically for the single specific consumer of the media.
