grk··on Firefox Developer Edition
For those not liking the dark UI, you can switch by opening the dev tools, clicking the gear icon on the right and selecting "light theme".
grk··on How We Work on Queries at GitHub
Looks like they're using https://github.com/basecamp/marginalia for the tagging.
grk··on HTML minifier revisited
I'd like to see a before/after comparison after gzipping the results.
grk··on A Comparison of Popular Ruby Application Servers
From my experience in running a small PaaS for ruby apps: if you want to have something that 'just works', go for phusion passenger. If you want to take advantage of threads, go with passenger enterprise.

If you want a more complicated setup, for example with varnish and haproxy between nginx and your application servers, thin is rock solid. It runs Rails 2.x-4.x apps without any issues. It's also well suited for handling websockets traffic.

If the workload of your apps can take advantage of threads (e.g. lots of external API calls, or lots of time spent in the DB), a server like Puma will show an advantage. Also, if memory is limited, you can handle more concurrent requests.

grk··on HTTP/1.1 just got a major update
Phusion passenger throws 500 on get requests with body, I guess now they might change that.
grk··on StartCom charges for reissuing SSL certs due to Heartbleed
Also, you can't issue a new cert for a domain until the old one is revoked.

grk··on Nginx 1.5.10 released with SPDY 3.1 support
They're at http://nginx.org/packages/mainline/
grk··on Hide your staging environment from Google (in Rails)
You're right, I edited the title to mention that.
grk··on Hide your staging environment from Google (in Rails)
That solution is fine, as long as your servers and all employees are in the same network (or use a VPN).

For those that work remotely, or use external integration tests for their staging environments, public access is OK.

grk··on Adding search and autocomplete to a Rails app with Elasticsearch
Searchkick uses Tire under the hood, but provides a higher level api. Also, Tire is getting retired in favor of elasticsearch-ruby, so Searchkick could switch the backend and you wouldn't have to change your code.
grk··on Ask HN: How to get beta signups
You could try http://erlibird.com/ - I did beta testing for a few apps from there.
grk··on Made a new modern styling for Gitweb
There's a preview here if anyone's interested: http://kogakure.github.io/gitweb-theme/
grk··on Life of an HTTP Request
The only difference in this case would be that Varnish will always pass those requests through.
grk··on Text-based terminal screencasts
http://ascii.io/ does the same and was around for a while, but showterm's text selection works better.
grk··on German discount host Hetzner launches new servers
I can confirm this, we're replacing at least two disks every month. You really have to design your architecture that allows a server to be taken offline for a few hours for disk replacement. Also, never use raid 0 on Hetzner.
grk··on German discount host Hetzner launches new servers
This is most likely a mistake on their site. The i7-920 doesn't even support this much RAM. For >32GB it has to be some kind of xeon, maybe sandy bridge E.
grk··on CoderPad

grk··on Is Shelly Cloud faster than Heroku?
We're planning to do this eventually, but we're focusing on EU right now.
grk··on Is Shelly Cloud faster than Heroku?
We're not saying that Shelly Cloud better than Heroku in general, we're just pointing out that focusing on one language has it's benefits. There is a market for generic solutions like Heroku, and specific ones like Shelly Cloud, Nodejitsu, etc.
grk··on Is Shelly Cloud faster than Heroku?
The tests were ran from a Hetzner server against Shelly Cloud and Heroku EU, so that shouldn't affect the results.

We are however targeting EU customers, we have servers in EU datacenters. We have plans to expand to the US later.

grk··on Is Shelly Cloud faster than Heroku?
By keeping the test apps simple, we limit the app code's effect on the results, and show the overhead of the providers' infrastructure.

You're welcome to fork https://github.com/shellycloud/baseline-performance and provide a better test.

grk··on Is Shelly Cloud faster than Heroku?
We support all Ruby frameworks, not only Rails.

We believe that by focusing on Ruby we can provide better service than we would if we had to support multiple runtimes and application architectures.

grk··on Is Shelly Cloud faster than Heroku?
To run redis, you only need to pay for the virtual server and storage, that's why it's not mentioned separately in pricing. You can run all non-replicated databases (postgres, mongodb and redis) this way.
grk··on Phusion Passenger 4.0.1 final release
I'd love to beta test this if you ever decide to implement :)
grk··on Phusion Passenger 4.0.1 final release
I'd love to see a 'phusion passenger for background tasks'. Managing large amounts of resque workers is a pain.
grk··on Rap Genius (YC S11) responds to Heroku’s call for ‘respect’
Speed and ease of development, mostly.
grk··on From Python to Ruby: Taking a Step Backward
Most rails apps are deployed on linux. I doubt there are any popular gems that depend on OS X. The problem might be with gems' dependencies, but that's a problem with linux, not ruby.
grk··on WhatsApp is broken, really broken
So, what's the best alternative?
grk··on Show HN: Wordsmith - jquery plugin that adds on-demand word definitions
That's really nice, but double-clicking a word is not obvious. Would it be possible to show the translate icon after you hover the cursor over a word for a few seconds?
