Restart the guest OS (Ubuntu) and VMware itself. It seems when upgrades VMware it’ll be overwritten dhcpd.conf.

This website shows bunch of iPhone apps that are featured in TechCrunch. Top 25 apps on App Store is usually filled by games but those are not very attractive to me. TechCrunch writes about iPhone apps which were made by brand new startups, and I like to check them out. So, to check those apps easily here’s this website.

Hope it saves educators’ research time. I’ve tried to find school/teacher name, location, grade, subject, tools and data/feedback for each example. Some cells are still blank. Please let me know if you’d like to edit. I’ll give you editor permission.

% sudo yum remove mongo-stable-20110131-mongodb_1
% vi /etc/yum.repos.d/10gen.repo
% cat /etc/yum.repos.d/10gen.repo
[10gen]
name=10gen Repository
baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64
gpgcheck=0
% sudo yum install mongo-10gen-server

When I tried to yum update mongo-stable, got conflict error “Error: mongo18-10gen conflicts with mongo-10gen”. I also needed to rewrite yum repository since my old config pointed at baseurl=http://downloads.mongodb.org/distros/centos/5.4/os/x86_64/.

It seems epel repository has mongodb package, when you “yum search mongo” you’ll probably find mongodb package aside from mongo-10gen which is a bit confusing.

I got this error with Firefox 8 (beta channel). With 7.0.1 which is the stable version, works well.

On this article it uses Celerity, but it gets the below error:

% HEADLESS=1 cucumber 
Celerity only works on JRuby at the moment. (RuntimeError)

Actually his source code looks different from his original one on the article. I couldn’t find Celerity in the latest codes.

I’m still exploring.

Upgrade to 3.6RC4 from 3.5 took some time and downgrade as well.
