3 Ways to Host Your Own Delicious Alternative – ReadWriteCloud I'm going to miss Delicious when it's gone. I might do something like this, but I'll need to get blog posting and an easy way to add links from browsers first. I might just try Pinboard.

Goal: Not To Be Acquired « Weblog Tools Collection Good for them if they don't want to be acquired. If I liked what I was doing and wanted to keep doing it I'd be doing the same thing. Getting bought out makes you wealthy, but doesn't necessarily add happiness. Why Working On A Large Enterprise Network Isn’t Always A Win « PACKETattack Ethan's list of ways big networks aren't fun is almost identical to the list of ways big server installations aren't fun.

Keys To Virtualization Success

by

I’ve been thinking a lot lately about what has made my virtualization journey successful so far. There are eight good reasons for my success, four of which tend to be more technical than the rest: a test environment, not breaking vMotion, N+1 capacity, and maintenance windows & good patching practices. 1. A respectable test environment. I have four physical hosts (two older hosts, two newer hosts) configured in two clusters where I can try new things, test patches and upgrades and functionality, run a couple test VMs for each OS we support, develop procedures, train staff, do demos, and generally muck around without affecting production. I run the test vCenter instance for these hosts as a VM in my production …

Amazon & WikiLeaks, DMCA & Perils of Public Clouds

by

On December 1, Carl Brooks of TechTarget published a piece entitled “Amazon boots WikiLeaks under pressure from U.S. Senator.” Yesterday he implored them to release a statement about what actually happened. I agree with him. I’d like to know what happened, replacing rampant speculation with as many facts as possible. Perhaps the delay is to permit Amazon’s lawyers time to sort this out, especially if it’s true that Lieberman interfered. It also may be true that their shutting WikiLeaks down has legal implications for them under DMCA Safe Harbor provisions. As stated by the chillingeffects.org DMCA Safe Harbor page: In order to qualify for safe harbor protection, a service provider who hosts content must: have no knowledge of, or financial …

Spread Linux’s Default Scheduled Jobs Out

by

By default, Linux distributions ship with a number of system maintenance tasks. On Red Hat Enterprise Linux (and CentOS, and OEL, etc.) they are scheduled via shell scripts in the /etc/cron.* directories, and executed by anacron. The problem is, there’s usually a default time they are executed, like 0400. And when you have 300 RHEL virtual machines all rotating their logs at 0400 you start seeing storage and CPU performance problems, as copies are made and logs are compressed. This can be true of hosts attached to SAN/centralized storage, too. If we ignore backup windows[0], my RHEL 5 hosts had three main offenders: /etc/cron.daily/logrotate: kicks off /usr/sbin/logrotate to trim and compress log files in /var/log. /etc/cron.daily/mlocate.cron: part of the mlocate …

Hard-Working Software Everyone Will Use

by

I’m cleaning my cube today. Not because of any employment changes, just that it looks like a bomb went off, and while I watch servers update themselves I can be doing something productive. That all went out the window with what I found between my defibrillator (a Burdick Medic 4) and my Cisco AGS+: It’s discoveries like this that actually make me want to clean my cube. Time to see if TechNet has Windows 3.1…
