I came across a new blog (seems to have come on-line in March) http://www.epoxyjournal.com. One of the entries was about how to clear command history. Everyone has inadvertently pasted or typed something into the wrong shell. Sometimes its worthwhile to clean up after yourself and sometimes its not. I figured I would offer a suggestion for the times you want to avoid having your embarrassing moments in your ~/.bash_history. Instead of blowing away your entire current buffer with history -c you can redirect it to another file, flush the buffer to the file, clean it up then append it to your ~/.
I just downloaded EMC Networker client for a 32bit linux box. The file I downloaded was nw74sp5_linux_x86.tar.gz. Of course when I go to extract it …. # tar zxvf ../nw74sp5_linux_x86.tar.gz gzip: stdin: not in gzip format tar: Child returned status 1 tar: Error exit delayed from previous errors Umm not in gzip format …. # tar xvf ../nw74sp5_linux_x86.tar.gz linux_x86/ linux_x86/lgtoclnt-7.4.5-1.i686.rpm linux_x86/lgtolicm-7.4.5-1.i686.rpm linux_x86/lgtoman-7.4.5-1.i686.rpm ... 🙂
They are only on their 3rd episode, but its been good listening so far. If your into networking check it out. http://packetpushers.net/
Gah, still recovering from a hardware issue that hit early Monday morning. Back to restoring data …
I have a love/hate relationship with cpanel. On one hand it makes low end hosting a breeze, on the other its a huge pita if you want to do anything “outside the box”. Perhaps it’s not such a pain if you work with cpanel frequently. But I find cpanel beneficial because it aids in tasks that I don’t do frequently, and can offload many of those tasks to less technical people.
Yesterday I had a tip on removing yourself from any testing for that google sidebar that your likely seeing in your search results now. I woke up to a nasty surprise. After removing the cookie yesterday, today I had the bar again. So I removed the cookie again, and it came right back. Thats when a friend pointed out that google was rolling it out to everyone. OH NO! Well, luckily you can get a browser extension for Firefox or Chrome that makes it disappear from the guys over at seotools.
This deserved a repost. Originally sourced from http://www.csua.berkeley.edu/~ranga/humor/500_mile_email.txt To: email@example.com Subject: The case of the 500-mile email. Date: Tue, 26 Nov 2002 14:57:40 -0800 Here’s a problem that sounded impossible… I almost regret posting the story to a wide audience, because it makes a great tale over drinks at a conference. :-) The story is slightly altered in order to protect the guilty, elide over irrelevant and boring details, and generally make the whole thing more entertaining.
Google is constantly doing experiments to see what its users like best. Today I was slapped with one of their tests, the “Everything Sidebar”. It really screwed with me and was entirely distracting while I was searching. So naturally I looked for a way to reverse it. It’s easy enough, you just need to delete a cookie. Here is a screen shot of the results page At any rate, if you want it gone just delete the PREF cookie from google.
I’m curious what anyone who reads this blog thinks. My first reaction when someone mentions Ubuntu server is to grab the nearest trout and start slapping. Don’t get me wrong I like Ubuntu. It’s very nice on a workstation, and suitable for my wife, mother, aunt, etc …. But do you really think its good enough for prime time in the data center? According to a server-survey conducted by the Ubuntu marketing team almost 80% of users see Ubuntu as ready for mission critical use.
Monitoring and analyzing performance is an important task for any sysadmin. Disk I/O bottlenecks can bring applications to a crawl. What are IOPS? Should I use SATA, SAS, or FC? How many spindles do I need? What RAID level should I use? Is my system read or write heavy? These are common questions for anyone embarking on an disk I/O analysis quest. Obligatory disclaimer: I do not consider myself an expert in storage or anything for that mater.
