Midnight is Always Tomorrow

by

“So, are you ready for the big power outage on Sunday?” a colleague asks on Thursday. “You mean Saturday.” “No… Sunday morning.” “Um, I was told two months ago, and countless times between, that the outage is on Saturday, midnight to 8 AM, and they were starting to shut things down at 10 PM.” “It’s Sunday, midnight to 8 AM. They’re going to start shutting things down on Saturday at 10 PM.” “Did they move the outage?” “No, I bet they were just telling you when things were going to start. On Saturday.” Midnight is 00:00, meaning the start of a new day. Always. If you’re in doubt, use 00:01. Assume everybody is clueless about time, because they are. For …

Adobe – Security Bulletins: APSB10-14 Security update available for Adobe Flash Player 32 security holes in Flash, all major enough to warrant CVE numbers, some critical remote code execution. It is no wonder why Apple refuses to allow Flash on its platforms. The only purpose Flash serves on my PCs is to show me ads.

VMware vSphere 4 Update 2 Highlights

by

I’ve been reading through the release notes for VMware vSphere 4 Update 2, and there’s a few big highlights buried in with all the bug fixes, at least for me. Of course, beauty is in the eye of the beholder, and if you were waiting for a bug fix that shipped that’ll be way more important than new functionality. Some of these are pretty big, though. 1. Enhancement of the esxtop/resxtop utility. esxtop & resxtop can now show you NFS datastore performance stats, as well as power statistics (via the ‘y’ key). Both are very welcome changes, but NFS stats are killer. 2. Speed and duplex settings for a NIC might not be retained after ESX/ESXi server reboots — fixed! …

Windows Reboot — Matt Mullenweg "Dear Microsoft, every time you reboot my computer overnight without me having any interaction I lose unsaved documents and messages. It completely breaks my trust in a way that’s irreparable. It’s been six years since I first wrote about this." I think a lot of people don't know about the options they have for Windows Update. You can set it to not automatically patch, but instead prompt you. Problem with that is that people then ignore it, and get hacked…

Twitter Blog: Links and Twitter: Length Shouldn’t Matter "When this is rolled out more broadly to users this summer, all links shared on Twitter.com or third-party apps will be wrapped with a t.co URL." People should keep in mind that the .ly domain is Libya, and they haven't been the most friendly in the past. Colombia might not be, either, but at least they aren't on the list of State Department non-export countries…

SLES For Free + vSphere 4.1 Information Leak

by

From the vmware.com page entitled “SUSE Linux Enterprise Server (SLES) for VMware:” When you make a qualifying purchase of VMware vSphere, the industry’s leading virtualization platform, you will be entitled to receive SUSE Linux Enterprise Server (SLES) for VMware and a subscription to patches and updates at no additional cost (see terms and conditions below).

I am a Red Hat Enterprise Linux person, but I know a …

It's A Family Thing

by

I’m taking an off-topic break for a moment to express my delight in popular culture, for a change. Those of you watching HBO’s Treme saw something this week that is summarized quite nicely by the New Orleans Times-Picayune, in their “Treme Explained” post: Antoine and Desiree barbecuing on a parade route illustrates an aspect of Mardi Gras that’s poorly understood by outsiders: The beads ‘n’ boobs “Girls Gone Wild” version of the holiday that Delmond briefly experiences elsewhere in the episode is largely confined to the French Quarter and almost exclusively perpetrated by drunken tourists, not that there’s anything wrong with that. For most local participants in the Carnival parade experience in New Orleans, the setting more resembles a family …

Disk Space Usage from the ESX CLI

by

Want to find out how much space is being consumed in your datastores, and by what? You can do this from the VMware ESX CLI using the ‘du’ command. For example, if you have a set of datastores named with the prefix “netapp-” you can display the disk usage for all of the virtual machines in them with: # du -s /vmfs/volumes/netapp-*/* 26214528        /vmfs/volumes/netapp-linux-1/vm-hr-1.company.com 40952192        /vmfs/volumes/netapp-linux-1/vm-payroll-2.company.com 49340800        /vmfs/volumes/netapp-linux-2/vm-payroll-1.company.com 48292224        /vmfs/volumes/netapp-linux-2/vm-hr-2.company.com 69263744        /vmfs/volumes/netapp-linux-3/vm-wiki.company.com If you’d like the output with human-readable numbers, try using ‘-h’ with du: # du -sh /vmfs/volumes/netapp-*/* 26G /vmfs/volumes/netapp-linux-1/vm-hr-1.company.com 40G     /vmfs/volumes/netapp-linux-1/vm-payroll-2.company.com 48G     /vmfs/volumes/netapp-linux-2/vm-payroll-1.company.com 47G        /vmfs/volumes/netapp-linux-2/vm-hr-2.company.com 67G        /vmfs/volumes/netapp-linux-3/vm-wiki.company.com Maybe you’d like to sort by VM name. Use the ‘sort’ command: # du -s /vmfs/volumes/netapp-*/* | sort -k 5 -t …
