We have a number of private npm packages, and I needed to create a new user, grant that user read-only access to our private packages. The npm docs are great. Really great. Go there for details. But here are the key commands for this (probably common) series of steps. Create a new team $ npm… Continue reading npm CLI Quick-Start for Organizations
I received a “high memory usage” alert. Already panicking, I logged into New Relic and saw this terrifying graph: That’s a graph of memory usage, starting from when the server was created. For the uninitiated, when memory usage grows and grows and grows like that, chances are very, very high that you’ve got a nasty… Continue reading Or: How I Learned to Stop Worrying and Love the Memory Leak
By default, Homebrew gets installed under /usr/local. This is great, because it doesn’t require you to use sudo to install and upgrade packages.

I’ve decided to use my mact.me domain name for this blog. The old domain name, yabfog.com, was just terrible. Enough was enough.

Same with familiarity: the less familiar I am with people, the more draining it is to interact with… Continue reading What is it about Twitter?
OSX has a ridiculously low limit on the maximum number of open files. If you use OSX to develop Node applications — or even if you just use Node tools like grunt or gulp — you’ve no doubt run into this issue. To address this, I have this line in my $HOME/.bash_profile: ulimit -n 1000000… Continue reading Yosemite Upgrade Changes Open File Limit
At some point, you’ve probably seen this message when you try to log in to one of your servers: This is really common when you have Amazon EC2 instances behind Elastic IPs because the IP address stays the same (and probably the hostname, too), but as new instances replace old instances, the new instances’ ssh… Continue reading Easily prune your ssh known_hosts file
