grk··on AWS multiple services outage in us-east-1
Does anyone know if having Global Accelerator set up would help right now? It's in the list of affected services, I wonder if it's useful in scenarios like this one.

Except the data linked in the article proves the exact opposite?
grk··on Delayed Job vs. Sidekiq
Not sure how it works with MySQL, but with postgres the most common pooling options use transactional mode, which doesn't support LISTEN/NOTIFY.
grk··on Delayed Job vs. Sidekiq
The problem with postgres-backed queues is they can't be used with connection pooling, so your workers are unnecessarily using up DB connections.

There are in-app purchases for coins, so I guess that's how?

grk··on In Denmark, Harsh New Laws for Immigrant ‘Ghettos’
I used to live in Tingbjerg, and could witness firsthand how the immigrants abused the welfare there. The laws may seem harsh, but on the other side you have people who take pride in cheating the social security system.

grk··on Rhetoric around the blockchain hints at problems with techno-utopian ideologies
I think there are usecases where you control the whole chain and have nodes within your organisation. The blockchain becomes a specialised database that's optimised to be a ledger, something like https://chain.com and https://chain.com/sequence/.

grk··on A $10K tiny house 3D-printed in 24 hours
Look up Finnish modular homes. They work in climates where temperature goes below -30C.
grk··on Electronic meters’ false readings up to six times higher than actual consumption
Most new apartment buildings in Poland have 3 phases connected to all apartments. Since there's municipal central heating, there's no point in connecting natural gas to those buildings, so you're forced to use induction stovetops. And those are much more efficient with 3 phases.
grk··on A deep dive into why Wi-Fi kind of sucks
Should I set channels on the APs in some specific way?

We're using mostly apple hardware + ubiquiti APs, and to be honest I expected everything to "just work" with the defaults...

grk··on A deep dive into why Wi-Fi kind of sucks
Thanks, that link is very informative.
grk··on A deep dive into why Wi-Fi kind of sucks
Does roaming devices between APs actually work? I reading through ubiquiti forums and it looks like they used to support it, but backed out of it.

My specific usecase is moving around the office while being on google hangouts on my phone.

grk··on Ask HN: Best Git workflow for small teams
We've been using the Github flow (or some variation of it) in teams of 2-10 people for a few years now. We work on feature branches, merge after code review using the github web UI. Here's a few things that help us:

- Make a rule that anything that's in master can be deployed by anyone at any time. This will enforce discipline for code review, but also for introducing changes that f.e. require migrations. You'll use feature flags more, split db schema changes into several deployments, make code work with both schema version, etc. All good practices that you'll need anyway when you reach larger scale and run into issues with different versions of code running concurrently during deployments.

- If you're using Github, check out the recently added options for controlling merging. Enable branch protection for master, so that only pull request that are green on CI and have been reviewed can be merged. Enable different dropdown options for the merge button (eg rebase and merge), these are useful for small changes.

- It takes some time to get used to those constraints. Make sure that everyone is on board, and do a regular review of the workflow just as you would review your code. It takes some time to get used to, but I think it's worth it in the long run.

grk··on Speeding up Rails 4.2
Ruby 2.2 will add almost-automatic-freezing of string hash keys[1]. I wonder how big of an impact this will have on Rails performance.
