jwcooper··on MacBook Pro Repair Extension Program for Video Issues
Consider me another Macbook Pro owner (late 2011) that had this issue. I've now gone through two logic boards. Luckily, the second was covered under the warranty of the first replacement.

Has anyone here been contacted by Apple for Reimbursement yet?

jwcooper··on Turbocharged Raspberry Pi 2 unleashed
There are many reasons.

The large community that is involved with the Pi. The large number of tutorials, and guides available. The incredible amount of accessories available and customized for the Pi. The Pi has the momentum. The odroid-C1 may be fantastic, but it's the first time I've ever heard of it.

jwcooper··on Hands-On with Microsoft's New Holographic Goggles
Depending on the resolution, it could replace your monitors at work (assuming the headset is light, comfortable, etc). Using a wireless keyboard and mouse, you'd have your computer with you anywhere in the home or office.

As a developer, having a wall of holographic desktop screen space in front of me would be amazing. My home office would look much better too!

I have no idea how far away this version of HoloLens is from that reality though.

jwcooper··on Show HN: Wysihtml – Open-source rich text editor for web apps
What issues did you have with TinyMCE? We recently moved away from wysihtml5 to TinyMCE and have been quite happy with the results thus far.

The latest releases of TinyMCE have been easy to work with, and relatively pain free for us.

jwcooper··on Firefox.html: Rebuilding Firefox UI in HTML
At the same time, it's likely much more expensive to code native apps than it is to just build an html/css/js app using chrome with a lot of the heavy lifting already done for you (at the expense of increased resource consumption).

A lot of these apps wouldn't exist if they couldn't have been built quickly and cheaply.

jwcooper··on NASA’s Orion Spacecraft Splashes Down in Pacific After Test Flight
Sort of. According to Wikipedia the plans are for the Dragon to be modified into the "Red Dragon" for future mars missions.

"Red Dragon is a modified SpaceX Dragon capsule for low-cost Mars lander missions using Falcon Heavy rockets. Plans call for a sample return rover to be delivered to the Martian surface while also testing techniques to enter the Martian atmosphere with equipment a human crew could eventually use."

jwcooper··on Chemistry of Cast Iron Seasoning (2010)
Here is an article that breaks down a baking steel vs a baking stone. The steel comes out on top, mostly due to the thermal properties of steel: http://slice.seriouseats.com/archives/2012/09/the-pizza-lab-...
jwcooper··on Introducing the Photon
I'm not sure what you're looking to do with bluetooth, but Adafruit has a few breakout boards using bluetooth: https://www.adafruit.com/category/255

(disclaimer: I work for Adafruit)

jwcooper··on Introducing the Photon
Nearly everything is open source; firmware, hardware design files, and an api compatible server: https://github.com/spark
jwcooper··on Electric Turbochargers: The Next Big Thing in Fuel Efficiency
Baby steps.

There is a huge distribution network of gas stations, refineries, and (right now) fairly cheap oil. I'd like to own a 100% electric vehicle right now for the price of a Prius (with similar range, cold weather capabilities, comfort, space, etc), but I'm not sure if that's possible yet.

I see no problem with making gas/diesel engines more and more efficient until they are replaced by cheaper electric cars.

jwcooper··on Retailers are disabling NFC readers to shut out Apple Pay
Seems like an easy retaliation for Google and Apple would be to just block the CurrenC applications from the app stores when they are released. It's very similar to what the retailers are doing by blocking Google Wallet, Apple Pay and paywave by disabling NFC.

Also, I just don't see the banks simply rolling over and losing their beloved credit and debit card fees. They will definitely find ways to make their money (sgentle mentioned through contracts requiring NFC, etc).

I've had a paywave for a while, and have used it at CVS quite a bit. Sort of annoyed it won't work anymore due to this issue.

And giving retailers direct access to your checking account via ACH..uffda.

jwcooper··on Apple Plans to Shut Down Beats Music?
This has been refuted by an Apple Spokesperson according to Recode [1]:

Tom Neumayr, Apple’s PR rep, says the TechCrunch story is “not true” but wouldn’t go beyond that.

jwcooper··on How ACH works: A developer perspective – Part 4
I think security, and maybe more so stability are very valid reasons for banks to move slowly on these systems.

It may appear archaic from the outside, but these systems are pushing $39 trillion dollars a year (22 billion transactions) [1]. I can see why the big banks are hesitant to change things drastically.

jwcooper··on The Galaxy Note Edge Is a Phablet with a Curved Edge Display
It's a neat idea in that I like seeing new uses of displays, and new ways to interface with them. Problem is, I think this would be rather annoying to use as a lefty, and others seems to agree [1].

jwcooper··on Notes on the Celebrity Data Theft
They have a 'store' link [1] right in their header with all the pricing. They could maybe be a little more upfront about it, but it's not really a bait and switch. Also, the prices do seem fairly reasonable for what it does.

The only thing holding me back has been not having great mobile access (as far as I can tell) on Safari on iOS. Looks like iOS 8 will change that.

jwcooper··on Two aid workers infected with the Ebola virus have been discharged from hospital
According to the mashable article [1] linked in the comments one component of the serum had some extended protection in a series of tests:

"A November 2013 Defyrus study showed that ZMAb offered extended protection against the virus. Scientists reinfected surviving monkeys 10 weeks after their first infection, and 100% survived. What's more, four out of the six monkeys reinfected 13 weeks after initial exposure survived."

jwcooper··on Chip-based credit cards are a decade old; why doesn’t the US rely on them yet?
We're getting there, albeit very slowly. Almost all the new readers I see at major stores now have the slot to slide your card in for the chip and pin. Every Target store I've been to appears to have been upgraded.

Wells Fargo has also started rolling out chip and pin credit cards, not sure if it's by default or not. I've had one for probably a year now.

That being said, I have no idea if the chip and pin even works end-to-end yet, as I haven't tried it. I'm likely part of the problem!

Also, we'll see what happens with the liability shifts in the US. Right now consumers have it fairly good with regards to fraud protection and getting reimbursed.

jwcooper··on Zillow Said to Be Seeking to Buy Rival Real-Estate Site Trulia
Problem is the data is so sketchy on Trulia and Zillow. I'd be interested in a house only to find out it already had a contingent offer accepted. They need to figure out how to get realtime data from the MLS systems.

Trulia and Zillow do have the best meta-data on houses though. School info, crime, purchase history, walk scores, etc.

jwcooper··on Zillow Said to Be Seeking to Buy Rival Real-Estate Site Trulia
I was originally using Trulia to send me emails on new homes in the market, and it works fairly well. Problem is that the data can be sort of dated fairly quickly as it doesn't get MLS data immediately (at least in my area). This is sort of troublesome in markets where a home can be sold in 48 hours from being listed.

Someone on HN mentioned Redfin, and I tried it out. It's incredibly fast (guessing 24-48 hours quicker than Trulia) to get emails on new listings as it's using the MLS data directly. Give it another year, and I feel like the UI will be on par with Trulia on the desktop.

jwcooper··on Expedia Starts Accepting Bitcoin for Hotel Bookings
Unless their employees, partners (hosting, etc) get paid in BTC, it actually does matter if they "sit" on the BTC they receive.

Many businesses and people still require to get paid in USD (EUR, etc) in order to do business. This may not always be this way, but as of today it is.

jwcooper··on Expedia Starts Accepting Bitcoin for Hotel Bookings
Does coinbase sit on the Bitcoins, or turn around quickly and convert to USD somehow (where?)?

Holding thousands of bitcoins as a startup seems like it would introduce a lot of volatility, even if the long-term prospects of bitcoin are good (still need to pay the employees).

jwcooper··on Microsoft launches Office for iPad
The Office for iPad looks much more optimized for touch screen devices, rather than having minor adjustments made to Office for desktop that RT looks to be using.

I'm guessing the usability differences are night and day between the two devices.

jwcooper··on Amazon Acquires Video Gaming Studio Double Helix Games
Killer Instinct is pretty popular, and fairly well reviewed. It did go with a model similar to League of Legends where you can play it for free, but then buy each character, or buy a pack of characters[1]. It's not a terrible model if it's priced fairly and balanced well. The characters do seem a little expensive, but if you play each one for more than a few hours, it's probably worth it in the end.

The worst offenders are games like Forza that are a $60 up front purchase, and then also have micro-transactions to buy cars (you can also grind many hours away to get them).

I believe Double Helix also has a game called Strider (related to the original arcade game of the same name somehow)[2] coming out soon that is somewhat anticipated.

jwcooper··on Bootstrap 3.1 released
Bootstrap 3 is much nicer to use than previous versions, if that's what you were using in the past. Each element is more of a barebones styling to it, which makes it easier to get what you want out of them (such as buttons). I spent a lot of time in previous versions of bootstrap just stripping out text-shadows, border-radius, gradients, and more just to get it back to a basic component.

The grid in the Boostrap 3 is pretty useful if your requirements are for a responsive layout. It really makes it pretty simple to get things going, but does pollute your html with a lot of cruft as you sometimes need to define each size within a single class attribute.

One other thing I've found is that it makes the site more maintainable, as it's easier for others to understand your CSS and layouts. It's the equivalent to being able to hire a Java programmer that knows the Spring Framework (they're plentiful, and usually know enough to not break things). The same is the case for Bootstrap. By having a common and popular framework, you have more developers that can jump right into your front-end quickly.

Also, it's easy enough to customize[1] to get only what you need. If all you need is the grids, just remove everything else. No need for the js components.

jwcooper··on NavSpark: Arduino Compatible with GPS GNSS Receiver
Arduino compatible is misleading in a lot of these cases. It usually means it works with the standard library included with the Arduino IDE, but most of the 3rd party external libraries (note...interesting and useful, and almost always necessary when connecting devices/screens, etc) don't end up working without changes to the libraries themselves.

Take a look at the amount of work that the Teensy3 community has done to make Arduino (atmel) specific libraries compatible with the ARM chip on the Teensy3. They're one of the few communities that have wide-ranging support with an ARM chip, but have put in a lot of time and effort to get it there.

jwcooper··on Thoughts on Google Glass
I like gadgets and various electronics, but for some reason Glass just rubs me the wrong way.

I'm not sure if it's because of the 'creep factor' or what. I guess I'm just not ready for a society always recording everything. I can't even imagine what high school would be like. One embarrassing thing happens, and 30 people have it recorded, uploaded to the internet, and commenting on it in minutes. I guess that could already happen with phones, but at least right now not everything is being recorded at every minute by every person.

If Glass use does become widespread, I have a feeling many private companies, such as restaurants, and malls will ban its use indoors, which would make it a pain to use (especially if it's connected to your prescription glasses!).

jwcooper··on Bootstrap 3.0.3 released
I've only ever used a SASS fork, and have never had any issues with compatibility or strange bugs. I think at this points it's safe to choose either LESS or SASS. The end-user won't ever know the difference, but you will.

Choose whatever pre-processor you're more comfortable using.

jwcooper··on Play, Scala, and Iteratees vs. Node.js and Socket.io
This is such an odd argument. As a developer that likes to produce usable products, 'easy' is something I'm always looking for. Why not? Just because something is 'easy' doesn't mean it's inadequate. It all depends on what you're building.

Also, your misguided rant against node and npm rather hurts your credibility. Your argument was at least ok up until that point.

jwcooper··on Drowning in JavaScript
Most properly built sites are already combining the JS and minifying it. It's a largely solved problem that is automated with the right tools. Not much added complexity in it.
jwcooper··on Playstation 4 - The Review
They cover that at the end of the review. It's basically the score of the system as it is today. It's a fair way to judge something that people will consider purchasing and wanting to have fun with right away. I wouldn't want to buy a console only to hope I have fun with it in 2 years (buy it in 2 years instead). [1]

"But the PlayStation 4's focus on gaming — and only gaming — is undermined by a distinct lack of compelling software. That failing is sure to improve — better games and more of them will appear on the PlayStation 4 — but right now, this is a game console without a game to recommend it. Early adopters of the PS4 this fall are buying potential energy. We're just waiting for a place to spend it."
