dkoch··on SnappyData: OLTP and OLAP Database Built on Apache Spark
Looks very promising!

Any plans to expose a Python API in addition to the Scala API?

dkoch··on Glacier redux
"Asked what IT equipment Glacier uses, Amazon told ZDNet it does not run on tape."
dkoch··on VPS Classic: The most afforable VPS
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
dkoch··on VPS Classic: The most afforable VPS
DigitalOcean's big selling point for me is SSD disk. I don't see that listed on the OVH offering.
dkoch··on SQLite vs MySQL vs PostgreSQL
"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··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.

dkoch··on Email (let's drop the hyphen) (2003)
The AP Stylebook switched from e-mail to email a few years back.
dkoch··on Only 90s Web Developers Remember This
My first job title was "webmaster." Which meant dev-ops-designer-product-guy.
dkoch··on Only 90s Web Developers Remember This
What about CGI scripts from Matt's Script Archive [1] which amazingly is still alive?

dkoch··on Rolls-Royce Drone Ships Challenge $375B Freight Industry
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··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.

dkoch··on Show HN: Abacus – Killing The Expense Report
How do you compare to big players in the market like Concur, which has these features?
dkoch··on How to Offer Google's Health Benefits on a Small Business Budget
Self-funded health insurance plans are very common with employers. Third-party administrators (TPAs) that provide the claim processing are big business.
dkoch··on Django 1.7 alpha 1 released
Yes. The author of South is writing the built-in migrations, and keeping a 3rd party migration library would be redundant.
dkoch··on San Jose Is Hell On Earth (1996)
It's pretty cool that at least two of the off-site links from that page are still live, considering how quickly most sites from that era fell into link rot:

"prefab hell" http://www.theatlantic.com/past/docs/issues/96sep/kunstler/k...

"sushi" http://www.lauralemay.com/essays/death-by-wasabi.html

dkoch··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··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··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?

dkoch··on Must-have Django packages
Don't be a pedant. The author uses the word in the sense of the slang expression "insanely great."
dkoch··on Must-have Django packages
I've found django-allauth a bit friendlier than django-social-auth, and it covers registration of local accounts in one package.
dkoch··on Tell HN: How we bootstrapped to the #1 rated mattress on Amazon.com
Do you use a sheet and a mattress pad on top of the mattress?
dkoch··on GTFO of my menu bar
I never would have noticed that the Dropbox icon was the only colorful icon up there if I hadn't read this article. Oh well.
dkoch··on Zurb Foundation 5 Released
It seems to have dependencies on core Foundation Javascript. I don't think it can be used stand-alone.
dkoch··on Zurb Foundation 5 Released
What do people recommend for functionality similar to Interchange on a Bootstrap 3 site?
dkoch··on Facebook Perl source code from 2005
At least they had "use strict" turned on. Not sure why they weren't using DBI and placeholders to prevent SQL injection attacks in 2005.
dkoch··on I know none of my passwords
A copy of the 1Password master password stored on the Yubikey could also be stored offline (safe deposit box).
dkoch··on Show HN: Introducing Harp – A static web server with built in preprocessing
Another nitpick about the source code:

Let the code breath a little -- no whitespace around control structures is a bit jarring:

  if(error){
    ...
  }else{
    ...
  }
Instead:

  if (error) {
    ...
  } else {
    ...
  }
Maybe adopt this Node style guide: http://nodeguide.com/style.html
dkoch··on The Hacker News Generation (Afraid of Hard Work)
I'm the parent of two toddlers and I can see how it happens. It's not quite as serious as leaving them in a hot car, but I've been in a rush and so distracted by work or life that I've put them in the car and driven away without remembering to fully buckle them into their carseats.

Realizing that you've potentially endangered them is an awful feeling, and a stark reminder to slow down and remember what's important in life.

Luckily they've gotten precocious enough to yell at me "Daddy I'm not buckled" so it doesn't happen any more.

dkoch··on MySQL is to SQL like MongoDB to NoSQL
MySQL has strict mode flags that can turn those silent "best guess" inserts into errors.

Triggers have existed since 5.0.2 in MySQL.

The query planner has been greatly improved with MySQL 5.6 and the MariaDB fork.
