"Asked what IT equipment Glacier uses, Amazon told ZDNet it does not run on tape."

Linode may outperform a similar DO box CPU-wise, but IO is no contest:

Here's a 512MB DO writing a large file:

  dd if=/dev/zero of=/tmp/out bs=1M count=4k; rm -f /tmp/out
  4096+0 records in
  4096+0 records out
  4294967296 bytes (4.3 GB) copied, 16.1503 s, 266 MB/s
A 2GB Linode of mine doing the same:

  dd if=/dev/zero of=/tmp/output bs=1M count=4k; rm -f /tmp/output
  4096+0 records in
  4096+0 records out
  4294967296 bytes (4.3 GB) copied, 36.4609 seconds, 118 MB/s

"Again, depending on the choice of the database-engine, MySQL can lack certain features, such as the full-text search."

Both of the two biggest engines (MyISAM, InnoDB) support full-text search. It was added to InnoDB in MySQL 5.6/Maria 10.

dkoch | 12 years ago | on: Why Puppet, Chef, Ansible aren't good enough

Ansible can be used as a distributed command runner but it's also a configuration management tool like Puppet (and much more).

Its "playbooks" are by default meant to be idempotent -- you can run them over and over ensuring that a system is in a consistent state.

I don't know anything about shipping, but I wonder how much of the crews' time is spent in maintenance and repairs. Are they trained to fix common issues? What happens when the robot boats break down?

Or are they just there to fill minimum crew size regulations and babysit ships that mostly drive themselves anyways?

dkoch | 12 years ago | on: Ask HN: do you use App.net?

Signed up for an account when they started offering free, didn't really understand the benefit because no one was there.

I have not been back.

Yes. The author of South is writing the built-in migrations, and keeping a 3rd party migration library would be redundant.

dkoch | 12 years ago | on: Ask HN: Do you bake AMIs for AWS deployments?

I think more flexible is a better word -- it can do more than what you can do when you bake a static image because you also use it to dynamically manage a running system post-boot.

Ansible can deploy all of your dependencies, keep them updated, push out configuration changes, and deploy your main application code.

I don't use AutoScaling, but no reason it couldn't be used with Ansible. The docs have a bit of detail on how to do it. http://docs.ansible.com/guide_aws.html

dkoch | 12 years ago | on: Ask HN: Do you bake AMIs for AWS deployments?

I create an AMI with a bare minimum OS. Then I use a configuration management tool to install all software packages, libraries and configurations. My new favorite is Ansible (ansibleworks.com) but Chef and Puppet are others.

Updates are easier this way versus having to rebake images.

dkoch | 12 years ago | on: Show HN: web app to create flippable brochures/magazines

The example looks very clean.

Reminds me a bit of treesaverjs.com, which created automatic magazine-like page layouts for any size screen, but unfortunately seems to have run out of steam.

Do you plan on offering a complete solution for publishers including CMS integrations?

Don't be a pedant. The author uses the word in the sense of the slang expression "insanely great."
