macos Big Sur 11.1 — ERROR: Failed to build gem native extension.

A while ago sudo gem update started throwing the following error: This wasn’t a big deal, as I wasn’t doing any any active ruby development, but it was still a minor annoyance. Missing directories reported in mkmf.log hinted at the cause: Searching for fixes resulted in a bunch of dangerous cargo-culted answers suggesting to curl […]

Is Google Chrome running obscenely slow on your obscenely expensive Mac Pro or Retina MacBook Pro with 4K or UHD monitor? Fear not…

My shiny Mac Pro just arrived along with a pair of Dell 28 Ultra HD (P2815Q) Monitors (2160p). I anxiously plugged everything in, fired up Google Chrome, and waited…and waited…and waited…and waited. The dreaded spinning pinwheel of death greeted me and it took minutes for each page to load. Not even the chrome://settings/ or chrome://version/ pages would load. Chrome was basically unusable. […]

How to murder a Blog

Short of a server going down, one of the quickest and most effective ways for a Blog to die is for it to drop out of search engines. Sure, you might have a ton of repeat visitors, but no search ranking means no new visitors because, well, no one can find you. What a blinding […]

Unfortunately, this artificially-low restriction can impact legitimate users who have multiple computers connecting to the Courier-IMAP server from behind a firewall or a single computer that runs […]

August RedHat Enterprise fixes break Plesk DNS

The most recent batch of RedHat Enterprise (RHEL) fixes rolled out this past week break DNS (bind) on servers running Plesk. My Plesk 7.5.4 installation was effected as well as many other Plesk 7.x and 8.x users. The problem appears to be with a conflict between RedHat’s bind-chroot RPM and Plesk’s chroot system. When the […]

They do more than just protect you…

One of my co-workers called me over to his desk this afternoon to show me an e-mail thread that had been bouncing around between a few of his family members. It went something like this: Original E-mail: Save those old phone bills! NY Times Article USA Today Article If you can’t access those articles for […]

MRTG cronjob retardedness

I’m running a combination of IOG and MRTG to keep track of network traffic and ran into a little bit of MRTG cronjob retardedness. In my haste to get MRTG up and running I forgot that it’s enabled by default on RedHat Enterprise Server even if you haven’t configured it yet. So, when I manually […]
