I wondered that too. When I was learning about timing and synchronization in distributed systems, I thought about building an app with a fake "heartbeat" that attempts to sync between everyone viewing the page. Had a brief moment

You actually can do this yourself quite readily, through use of CloudWatch billing metrics (which can be broken down by individual service). Define some alarms based on billing thresholds, and perform automated scaling actions in response.

How is it compatible, specifically? Do you replicate the same API in the skeleton app you distribute? Or is it possible to drop the Crosswalk View into a Cordova app directly?

This is pretty cool. Sounds like an alternative to PhoneGap/Cordova for high performance apps on Android. It appears it's meant to address the problem of building something like a mobile game with WebGL.

This is really cool - I wish I'd had this for teaching git a few weeks ago. FYI - it looks like branch creation is broken. Creating a branch and following with `git commit` gives the error "Not a good idea to make commits while in

As an aside - is it going to be prohibitively difficult for casual users like myself to become part of the elite now? If all but the most useful/insightful comments are stuck in pending until deletion, it'll be difficult to slowly

I did read it - it appears I misunderstood you though, sorry! For some reason, I interpreted the last two paragraphs as saying they were similar.

I agree with the idea in principle, that electric cars are a net positive for reliability and minimizing service costs. However, when you talk nostalgically about the good old days of cars being "mechanical devices one could understand

You can pay users to join your service and download your app, but that doesn't mean they'll become monthly active users, which is the metric your business will be valued on. This is a user acquisition tactic like any other - it do

Saw that reference in the linked post from Heroku in the original article. Has anyone used this? Is it configurable, or do they just choose some reasonable defaults?

If pgbouncer makes this big a difference to performance, is it included in managed PostgreSQL services, such as Amazon RDS and Heroku Postgres? Or would you have to roll your own pgbouncer setup for these systems?

What's the difference in wallet security between bitcoind and this library? At some point, you HAVE to store some hot wallets on a server. Is it easier to implement a dynamic cold storage system for wallets without bitcoind?

Quick note to anyone looking to build bitcoin-based apps - although something like this is probably useful for some applications, you don't actually need a complicated bitcoin client library to interface with the blockchain. The bitcoi

It seems like a simple solution to me would be to make the game free, but with most features blocked behind a SINGLE in-app purchase. That way you can download it, play what amounts to basically a demo, and decide if you like the game. If y

Ok, that's probably enough for my learning purposes. Thanks! Not having looked through all the problems yet - do they all have a reasonable test harness that gives you some sort of score?

Same situation here. I'd love to work through the problems at my own pace over the next few weeks though - I'd also like a way of replicating the solution testing that Stripe performs when you do an actual submission. Is that infr

This looks nice, but I'm not sure the solution to the overwhelming amount of content out there is more curation. I can't see myself having the time to build the perfect set of "troves". Instead, I'd like to see more

I know this is a little nitpicky, but your Python example has way more brackets than are strictly necessary. if post.created_at < datetime.now() - timedelta(minutes=5): I agree with your argument in principle though. Just wanted

Sounds pretty effective to me. Thanks for sharing this. Possibly stupid question - how do you retrieve all the expired keys? I was under the impression that once keys expired, they were effectively invisible to clients?

What's the algorithm you use for consolidating those repeated writes? I've thought about doing something like this in the past, but was put off by the worry that there might be edge cases where data would be lost (e.g. insufficien

I don't see why not - use a relational database for storing long-term data, such as users, friendships, preferences, etc. and store ephemeral data such as location in a key-value store like Redis. Store summary statistics of the locati

This sounds like an awesome idea, and a product I'd definitely use. Just a tip though - I had to read halfway down the page just to find out what nvlope.com IS (an email client with an API). "It's time to move email forward
