Dear Javascript coders: If you wind up writing the word "await" in your codebase more than once, you're doing it wrong. You will quickly see how futures/promises wind up taking over all of your code. This is a very good

Could you run the service off a few OVH dedicated boxes with 3Gbps? Sure, you could, but it's going to be painful, and at that point imgur is the better choice anyways.

Equivalent pricing: Amazon Cloudfront: $59770 per month Google Cloud CDN: $50000 per month Fastly: $144200 per month etc etc. If they can't get together $12000 per month for Cloudflare, they sure as hell don't have a viable busine

"As Vault is run within our internal network (and for other reasons), TLS is disabled. " No. No. No. No. No. No. This should NEVER be an option. You should not allow data to pass unencrypted over the wire, period.

What a load of crap. Lightbend released Lagom for Java because... drumroll.. Lagom is meant to bridge the gap between microservices and legacy Java monoliths.

Then you need to be deploying HTTP/2 over TLS. You are doing a disservice to users with slow connections due to the cost of opening up multiple sockets. Multiplexing your data over an encrypted channel over HTTP/2 and TLS will b

What you're seeing are apps that aren't optimized for mobile. Once you start moving application logic, network IO, and anything that doesn't involve the DOM off the main rendering thread via a cached ServiceWorker, mobile web

Pardon me while I go off on a bit of a rant. I've played with Vesper and it is a fine app. It is also the perfect example of the power of the web. There isn't anything that Vesper is doing that can't be done on the web. You c

"This would also let you charge spammers a lot" should be rewritten to "This would also let you charge unwitting victims of credit card theft a lot, and get a ton of chargebacks".

Please don't continue to run this. What you are doing is effectively recreating the VRFY command that nearly every major mail hosting service has removed for privacy and abuse reasons. You are opening yourself up to a huge liability,

Primarily merging the changes that Cloudant (now an IBM product) made to Couch to turn a fairly simple implementation of NoSQL / MapReduce into a first-class datastore. Things like: * Native Lucene search, which you had to build as a w

That's the other option; sending both session cookies at the same time and having the server do the work. Google's solution pushes that "if (short_session != valid)" logic to the client vs having it run on the server.

Yes; and CPU is cheap as hell. Round trips to a cache are expensive .

"The session has to be fetched from cache/hot memory on every request, right?" Nope. Let's say you have a rest endpoint that accepts a Pokemon id to add to your collection. If you cryptographically sign a cookie that say

by mark242 10y ago
You don't need to verify the session on the server all the time. Session verification very quickly becomes a bottleneck to app performance, since you're doing a separate database/cache lookup for each rest endpoint request. I

Yeah; $10 says there's a preference coming "Only show notifications from verified accounts" or "Only allow verified accounts to follow" etc etc.

This is where I think Scala really, really shines, regardless of whether you're using Akka or not. Once you've gotten into that mode of using futures, turning your code from blocking to nonblocking is as simple as never writing th

Yes, this. If you are working with any sort of confidential data, be it personal information, or payment info, or whatever, a determined attacker with access to executing Javascript on your page is going to cause a world of problems, the

Okay, the better question then would be, how does this compare with writing a processor on top of Akka streams?

A void function that does nothing but throw exceptions. Scala engineers everywhere cringe at the thought of converting this kind of code to native Scala.

Absolutely yes. Connections are very very cheap to maintain, and very very expensive to build up and break down. Even in environments with load balancers, stateful firewalls, etc., it is much easier to keep a socket open than it is to creat

"Heaps in the 1-2 GB range are not uncommon." Is this really still a complaint in 2016? Your phone has that much RAM. Honestly if you're worried about Java heap size, spin up a t2.medium instead of a t2.small for your build p
