jwcooper··on How Sidekiq makes $80,000 a month
Sidekiq is open source (LGPL). There is a free version that is pretty powerful: https://github.com/mperham/sidekiq
jwcooper··on Google buys Eyefluence eye-tracking startup
At the last Oculus Connect, Michael Abrash covers some of the high level issues they've seen with fast and "virtually perfect" eye tracking that is required for VR [1]. He predicts it should be doable within the next 5 years (including new rendering techniques required for foveated rendering).

His entire keynote is great, particularly if you're interested in the near-future possibilities of VR.

jwcooper··on Robinhood Gold
> Execution on RH is already pretty poor, this seems like a recipe for disaster.

Can you explain this? I like Robinhood for the free ETF and index trades. Haven't really noticed any issues in the year I've been using it.

jwcooper··on Nintendo Soars as Super Mario Mobile Game Comes to the iPhone
They (along with Google and the Pokemon Company) also invested up to $30 million into Niantic, the developer of Pokemon Go a year ago [1].

jwcooper··on Ask HN: What keeps you from exercising?
One big reason is the weather. I run outside all summer, and then it gets very cold where I live from December through February. I'm not insane enough to run outside on icy roads, etc.

We finally got a trainer for a road bike we can use during the winter, but it's not the same as running outside so I usually get burned out on it.

jwcooper··on What Danes consider healthy children’s television
I don't really have a problem with our kids having some screen time (without commercials, because it's so easy now), but we had to drop Youtube Kids because of this very reason as well.

Amazing that Google thinks that unboxing videos of products paid by the companies to the "entertainers" is good content for developing minds. I was under the assumption that app was curated, but it must not be.

Amazon's Freetime Unlimited with a Kindle and a soft case has been the best setup so far. Lots of educational stuff from PBS, but they can also mix in the Pokemon or super hero cartoons.

Surprisingly (or not), the kids sort of gravitate towards the more educational PBS shows.

jwcooper··on Pokémon GO: The Data Behind America’s Latest Obsession
Nintendo (along with Google and the Pokemon Company, which Nintendo also partially owns) invested $30 million into Niantic 9 months ago [1].

jwcooper··on Amazon Prime Strikes Deal for Most PBS Children’s Shows
The website and PBS kids video app have maybe 3-4 episodes of each show. Not even close to what Amazon will now carry, and what Netflix used to have.

Also, from what I've seen most kids (mine included) are now watching PBS via streaming apps and not live tv. PBS is now locking most of their kids content behind one corporation.

jwcooper··on Amazon Prime Strikes Deal for Most PBS Children’s Shows
The problem isn't with Amazon having to pay to serve the content. It's that Amazon now has an exclusive deal and this content is being removed from Netflix and other streaming services.

As others have noted, this isn't a great deal for consumers who also happen to already pay for some of the content via taxes.

jwcooper··on Atari co-founder: mobile games make me want to throw my phone
This is the biggest problem for sure. So many of these games just get buried in either app store by the worst type of games and apps.

I've mostly discovered them over time by recommendations from people, or from discussion boards or sites that cover games, or even when they get featured by Apple in the app store.

It's amazing that app discovery is so difficult to solve for the big app stores.

jwcooper··on Atari co-founder: mobile games make me want to throw my phone
If you can get past maybe the top 50 or 100 grossing games there are a lot of really good games out there that aren't looking to leech money from you. I have plenty of games that have been worth every penny I spent with a lot of depth and strategy required in order to master them.

Letterpress, Spelltower, Hearthstone, Tiny Wings, Ticket to Ride, Strategery, GD Swarm, Ridiculous Fishing, Monument Valley...I could go on and on. These games were all priced probably too low for what they offered in time played.

This is almost a fluff piece to promote a developer coming up with 'something new for mobile'.

jwcooper··on VW 'Dieselgate' software developed at Audi in 1999: report
You didn't need to buy it new from a dealership to get the package.

I bought mine used from a 3rd party dealership (non-VW specific), and still got the goodwill package.

jwcooper··on Visa: Some merchants see dip in fraud thanks to chip cards
They really want you to use the debit card portion of your card. I believe it involves the retailer paying lower fees. It's why every terminal is trying to funnel us into it, and doesn't have an obvious way to choose credit half the time.
jwcooper··on Visa: Some merchants see dip in fraud thanks to chip cards
My card now has pay wave (contactless), chip (and pin when required), and magnetic stripe.

It's a crapshoot which one will work at any given store. I do prefer the chip over swiping due to having to replace cards so often when the stripe wears out.

Contactless is listed at a lot of places, but it doesn't work consistently for some reason. Makes it hard to trust using it when the store is busy.

jwcooper··on Atom 1.6 Released with Pending Pane Items, Async Git and Top and Bottom Bar API
Check out nuclide.io. It's built on top of atom by Facebook. I haven't tried it, but one of its features is remote development using client/server.
jwcooper··on Apple’s declining software quality
Indeed, I rarely have any kernel panics, or system crashes on OS X, and especially iOS with the latest iPhone. Other than iTunes, their software (that I use) has been pretty good lately.

I've actually had more problems with the hardware. My late 2011 Macbook Pro was just returned from the offsite Apple Repair with it's 3rd logic board (that being said, it's still under an extended warranty from Apple, which is at least a consolation prize).

jwcooper··on Dropbox closing Carousel and Mailbox
They're killing the apps I actually use from them. Carousel was quite useful for all of the photos I've uploaded, and handles uploading the photos pretty well too.

This is finally giving me the opportunity to explore using some of the other cloud storage such as Google Drive or even iCloud where I can save some money each month as well.

jwcooper··on The Rocket Man Who Wants To Beat the Billionaires
The crafty engineer was Charles Steinmetz, and the business owner balking at the invoice was Henry Ford [1]. EDIT: Maybe not so true after all [2].

I had never heard of Maston Space Systems. It's amazing they were able to compete with such massive names in Boeing, and Lockheed.

jwcooper··on Volkswagen rigged tests on 2.8M cars in Germany, Berlin says
Most people seem to be saying that it will be a simple software update to fix this issue, and everything will be fine other than some loss of power and fuel economy.

Isn't it possible that running these engines at the EPA recommended levels just isn't possible? That if they were to run like this 100% of the time, reliability, mpg, or power would be greatly reduced for various reasons?

There is a reason they took this huge risk to put in the cheat (but maybe management didn't think it was a big deal). It seems like there is too much risk involved in cheating for just minor fuel economy and power gains.

jwcooper··on Volkswagen Is Ordered to Recall Nearly 500k Vehicles Over Emissions Software
California didn't originally detect this. According to the letter from the EPA [1], it was a team at West Virginia University doing a study that discovered that TDI's in normal usage were found to have significantly higher emissions. California's CARB then dug into it to confirm their results and work with the EPA to figure out what was happening.

jwcooper··on Apple Introduces the iPhone 6S and iPhone 6S Plus
They're not handling the financing. It appears to be going through Citizens Bank, and is an installment loan. [1]

And, if you were hoping to use someone cheap like Cricket instead of Verizon, no such luck there either:

"1. The iPhone Upgrade Program is available to qualified customers only with a valid U.S. personal credit card. Requires a 24-month installment loan with Citizens Bank, N.A. and iPhone activation with a national carrier — AT&T, Sprint, T-Mobile, or Verizon. "

jwcooper··on Windows 10 Review
My biggest issue was the metro stuff; mostly the default apps that would open in full screen mode.

Opening a PDF or an image in a new Windows 8 installation was always a frustrating surprise.

The start menu was confusing, and anytime you'd go into a metro-type application it was jarring.

jwcooper··on Windows 10 Review
For all the negativity, I really like Windows 10. I had been using Windows 8.1 and consider it to be one of the worst desktop operating systems I've used in the last 10 years. That's partially why I like Windows 10 so much. They fixed so many of the backwards ideas that came with 8.1.

That being said, I mostly use it as an entertainment consumption device these days. I have a PC that I use solely to play games and watch shows. My every day computer for development is now a Macbook Pro with OS X and all the nice posix-like tools included.

I think that's one of the bigger long-term issues Microsoft might be facing. It seems in the last 5 years or so there has been a fairly large exodus of developers from Windows to Linux or OS X.

jwcooper··on Oculus Rift
Looks like they may have IR LED's around the outside that are used by the camera for positional tracking. Might also be used to track finger movements on the inside of the ring, but not sure there.
jwcooper··on More Consensus on Coffee’s Benefits Than You Might Think
Coffee is ingrained into the culture of many professions, far beyond just office jobs.

Nursing, landscaping, utility work, construction, you name it...it's a great way to kickstart the body when having to get up at 5am or, stay awake during an overnight shift serving tables at a restaurant.

jwcooper··on Popular JavaScript Package Manager Npm Raises $8M, Launches Private Modules
NPM also offers NPM enterprise, which is $20/user/month. That adds up if a few big companies want a privately hosted NPM infrastructure.

I'd assume they continue to launch more services as time goes on.

jwcooper··on To Raise Productivity, Let More Employees Work from Home (2014)
I think being forgotten while working remote can be a concern, but it can be mitigated by the type of company you're working for.

If you're one of a couple people working remote and the rest of the team is at the office, you'll likely have a more difficult time being promoted and feeling included. If your company culture depends on remote workers it's not as big of a deal.

We have group chats, and video conferences that make it feel much more social and connected and being part of the team. Some roles require being in the office, but most developers and engineers can be successful remote with all of the modern tools we have for communication.

jwcooper··on Amazon Dash Button
Nearly everything arrives separately already with Amazon, so not that big of a change. They seem to ship things from different warehouses half the time.

I'm not sure I understand the blowback on how and when to push the button. It's only for amazon prime members right now, so presumably you'll press the button when you need something within the next few days.

Do you wait until you are completely out of something, drop everything and drive to a store and buy it, or do you plan ahead? Same thing here without having to go to a store or write it down on a list to remember.

jwcooper··on This is what happened when I drove my Mercedes to pick up food stamps
"Think of all the people in 2008 who didn't know not to get an ARM, and who might have been pushed into it by some "advice" they thought was good."

They'd likely have really low interest rates [1] right now due to the federal reserve keeping the rates low, and presumably refinancing soon now that house prices have risen quite a bit (depending on your market, and loan details, of course).

The 6-month libor, which a few ARM's are pinned to is currently at 0.4%, in 2008 it was around 3%, so your ARM could potentially have a lower interest rate of around 2.6%.

If you didn't lose your job, and had a 3-5 year interest only ARM in 2008, it's possible you could have benefited from it (again, depending on your local housing market). This obviously didn't work out well for everyone, but ARM's are a risk that can pay off as well.

That being said, once rates start rising (possibly soon, according to the fed[2]), there could be another foreclosure bubble of people sitting on ARM's watching their rates climb up.

jwcooper··on Nintendo Opens Door to Smartphone Games
They've been driving towards this for a little while now. There are a few F2P games on the 3DS already.

I'm guessing those games did fairly well (some were fun, and fairly priced) and Nintendo is realizing the potential of using their IP on a massive audience.
