Are you looking for a Dropbox alternative? Try ownCloud. Dropbox and ownCloud are both free as well as a paid service. The main difference between the two is that you can run ownCloud from your own server. Like Dropbox, you can access ownCloud from your browser, desktop or smartphone. The ownCloud server software runs on any server, mine runs on Ubuntu Linux, and it doesn’t require special permissions.
The latest version is ownCloud version 6. I was still running on version 4.5. So, the following instructions will upgrade your ownCloud to the latest version on the Ubuntu server. If you have large amounts of data, it would be wise to backup your ownCloud directories. If you don’t have many files, you can opt for a clean install.
Go to your ownCloud directory.
Delete everything except for data and config. You will most likely need sudo to delete your files. I opted for a clean install, so I deleted everything.
ls | grep -v 'data\|config' | sudo xargs rm -r
Download ownCloud. Since I did a clean install, I went up one directory level.
Unpack the tarball. It will create a new directory ‘owncloud.’
sudo tar xfj owncloud-latest.tar.bz2
Give it write permissions. By default, the owncloud files are owned by nobody. So, you might see an error message saying it needs write permissions to ‘owncloud/data.’ I changed the ownership of the files to Apache, which is www-data.
sudo chown www-data:www-data -R owncloud
Access ownCloud by opening up your web browser and going to your ownCloud URL. If you did a clean install, you will be asked to create a new admin username and password. Otherwise, enter your former credentials. Finally, download the desktop clients as well as the mobile apps and install on your devices.
Synch your files and have fun.
I installed a couple of Engenius ENS202ext Outdoor access points for a client the other day. The range on these AP’s are extremely good. The device operates at 400mW Transmit Power. It has two omnidirectional antennas rated at 5dBi each. They can be replaced with even a higher gain antenna. It supports 802.11 b/g/n Wi-Fi standards running at 2.4Mhz. The maximum data rate is 300 Mbps. Each SSID can be tagged to a separate Vlan and they come with the EZ controller which is a free download. The Engenius ENS202ext Outdoor AP currently sells for under $100.
The other day, I read that Twitter was trying to make its profile pages to look more like Facebook. A few weeks ago, I recall reading that Facebook was trying to make its real-time conversations look more like Twitter. I really don’t understand. So, why don’t these two tech lovers, both headquartered in the San Francisco Bay Area by the way, just get together and consummate. Then, we will have one giant social media called Facetweet. Think about all the time we will redeem if we post on just one social media platform. We will literally cut our social media time by half. Just think about how we will have more time to ourselves, how we could be more productive, and have a better quality of life. Maybe not.
I put on Google Glass for the first time ever today. I was trying to browse a website. The side buttons were hard to find. I was just pressing anything on the side to see if it would do something. The screen was awfully small and it was blurry. It must have been my bad eyesight because I had to take off my eyeglasses to put them on. You would think it would be sharp since it’s only a few inches away from eyeballs. The screen is situated just over my right eye. What if my left eye is dominant? Does Google have them? Overall, I’m not impressed at all. They guy who was demoing me the unit told me that he doesn’t like it either. So much for that. For the $1500 price, it’s totally not worth pursuing. It’s got a long ways to go.
I’m at a Responsive Web Trends Conference in San Francisco hosted by Moboom. The network setup is a bit unorthodox. The subnet mask is set to 255.0.0.0. Based on my experience, this network is /8, which allows up to 16,777,214 hosts. It uses the entire range of reserved private IP addresses starting from 10.0.0.0 to 10.255.255.255. Interesting setup. I just ran a speed test. Download is 50 Mbps and upload is 27 Mbps.
Mozilla plans to sell sponsored content, just a fancy word for advertising, in its new Tab pages. The New Tab pages will have some Mozilla-specific content, some popular websites, as well as some hand-picked sponsored content. Mozilla receives about $300 million per year from Google for making Google the default search engine for its Firefox browser. The deal is due up in December. Could it be that Mozilla is just trying to diversify its income stream just in case Google changes its mind.
Shirley Temple died today at the ripe old age of 85 in her home in Woodside, CA. I’ve seen tiny snippets of her many films on TV shows, but I’ve never a full movie until I saw the Little Princess. The film was set in a Victorian London when Sara, played by Temple, was left behind by her dad to fight in the Second Boer War and the Siege of Mafeking. Temple and and a co-star Arthur Treacher had a musical number together, performing the song “Knocked ‘Em in the Old Kent Road.” If you haven’t seen the film, check it out. And with that, I will have a Shirley Temple tonight!
The power of influence on friends and family. That’s Microsoft latest plea to get everyone off Windows XP which ends support on April 8. Running Windows XP past the deadline mean potential security issues since Microsoft will no longer apply fixes or patches to security vulnerabilities. Experts estimate 30% of the web are still using Windows XP. Running Windows past April 8 is akin to running wild in a lawless country. Your on your own. But, didn’t you feel you were on your own the whole time anyways. The article from Ars Technica.
PC World has a very interesting article entitled, “Unveiling ‘The Mask': Sophisticated malware ran rampant for 7 years.” It’s also known as Careto, a sophisticated malware that ran rampant and undetected for 7 years. It has infected hundreds of government and private organizations in more than 30 countries. Kapersky Lab, an antivirus firm believes the virus could be state sponsored. Excerpt of the article from PC World:
“When active in a victim system, The Mask can intercept network traffic, keystrokes, Skype conversations, PGP keys, analyze WiFi traffic, fetch all information from Nokia devices, screen captures and monitor all file operations,” the Kaspersky researchers said in the research paper. “The malware collects a large list of documents from the infected system, including encryption keys, VPN configurations, SSH keys and RDP [remote desktop protocol] files. There are also several extensions being monitored that we have not been able to identify and could be related to custom military/government-level encryption tools.”

3D movies are typically a bit more expensive than your normal run-of-the-mill movie. Part of the reason why it’s expensive, is because of the high cost of production. Special 3D cameras are needed. There is a special editing process, as well as the cost of giving away those 3D glasses at the movie theaters. They all contribute to the high cost of production. But, don’t throw those glasses away. Take them home instead. Why save them? Well for one, you can use them with Google Maps. Yes, Google Maps has a 3D feature. Just go to the Google Maps ‘Street Level’ and switch to 3D. Don’t get rid of the 3D glasses just yet, even if it will make you dorky. Keep them around. So, the next time you are checking someone else’s address, just put on the 3D glasses and enjoy the view.
