YouTube now defaults to HTML5 YouTube Engineering and Developers Blog: Four years ago, we wrote about YouTube’s early support for the HTML5 tag and how it performed compared to Flash. At the time, there were limitations that held it back from becoming our preferred platform for video delivery. Most critically, HTML5 lacked support for Adaptive Bitrate (ABR) that lets us show you more videos with less buffering. Over the last four years, we’ve worked with browser vendors and the broader community to close those gaps, and now, YouTube uses HTML5 by default in Chrome, IE 11, Safari 8 and in beta versions of Firefox. ...

JPEGMini What if you could reduce the size of all the jpeg pictures on your hard disk? Do you have problems sending full resolution jpeg images via email because of size restraints? Is your iPhoto library too large? Let’s face it; pictures is one of the things that sucks up space on your drives. It’s even more annoying if you are using a newer Mac with an SSD disk where cost is premium. Upload speed when sending emails or uploading images to the web can be slow and annoying. An application called JPEGMini claims to help you with reducing your pictures with up to five times while retaining all the quality. I got a bit curious if the team at JPEGMini and their patented image compressor really could reduce large JPEG photos without losing quality. I’ve tried the application before when I wrote my article about comparing the best jpeg compressor applications for web use. But even though JPEGMini is geared more towards large megapixel pictures, not small images usually used on web pages, my test shows that it stacks up well against the competition even on more modest photographs. Many web pages now use pictures optimized for high-resolution images like for Retina display and high-resolution mobile devices, so the use of an image compressor is getting even more useful for web use. But how well does JPEGMini retain quality on megapixel images in JPEG format? How much do you lose in quality by using compressing? ...

There are several JPEG image compression tools available that takes a jpeg file and reduces the size of the photo without altering the quality. But which one works best for posting images on a website? I was curious, so I took the tools I usually use and put them through the compress photo function. All applications tested claims not to lower the quality of the image. I’m concentrating on testing jpeg files here, and do a followup article later with results for optimizing PNG files. ...

Google Reader joins graveyard of dead Google products - Slate Magazine: It’s hard to lose a loved one, especially if that loved one is a Google service. That’s why we’re opening the gates of the Google Graveyard, a virtual space for grieving. Buried in these hallowed grounds are some of Google’s ill-fated services. Some, like Google Reader, lived long, prosperous lives, full of admiration and glory. Most, like Google Wave and Google Buzz, struggled to carve out a place in this harsh, unforgiving world where technologies continuously clash and innovation reigns king. But whether these services transformed our productivity or only polluted our inboxes, they all touched our world in some way. ...

Initial installation Ubuntu Server Last time I configured my web server with Ubuntu Server, I had problems finding all the instructions on what and how to install everything needed to get a WordPress blog with W3 Total Cache, CDN, Apache2 MPM Worker and fcgi working. So this is my attempt to write down the steps needed to get the server going. You might find it of interest if your needs are similar to mine. Here’s the requirements for my WordPress blog.

When setting up my new web server I had a problem when installing vsftpd on Ubuntu Server 12.04 LTS. After doing the sudo apt-get install vsftpd and enabling login for local users, I got a “Server 530 login incorrect error” when trying to connect with a local user. The settings for disabling anonymous login and allowing local users where set in /etc/vsftpd.conf. [cc lang=“bash”]anonymous_enable=NO local_enable=YES write_enable=YES[/cc] But the ftp server still refused to let me login with any of the users on the system. I tried remove and reinstall, but the problem persisted. Finally I found a thread where others had the same problem. And here’s how to fix the problem. [cc lang=“bash”] sudo apt-get remove vsftpd sudo rm /etc/pam.d/vsftpd sudo apt-get install vsftpd [/cc] ...

SSD My old web server built on old spare parts had a hard disk crash a month ago. So I had to put it up on my BlueHost account while waiting to get hold of a new disk. I decided to try out a SSD disk, so I got hold of a 60gb IBM SSD disk. Without any optimizations, it can now handle double the traffic! I’ll continue to optimize tomorrow to get the most out of it. I’m doing an article on how to set up a LAMP server on Ubuntu Linux for WordPress with all the stuff needed to get W3 Total Cache, APC and other stuff working, because I can’t find a good article that describes everything. I will start writing on it tomorrow.

When changing permalinks in Wordpress from an old format to a new, you risk losing Google page rank. On my blog, I’ve had my permalink set to /archives/year/month/day/name-of-article. Looking at my web server log, very few used the archives sidebar, so I removed it. To make the link shorter I needed to remove everything except the article name. But when changing the permalink, all the incoming links will get a 404 error from all old connections, and the search result from Google, lowering your Google ranking. Not good. ...

So, after doing an upgrade of my Apache installation all my web content stopped working. It continued to give 403 errors. After spending hours changing permissions and checking every little detail I gave up. So I installed Nginx instead. It’s a bit scary to start using a totally new web server software, but why not live dangerously? Anyway, it’s fast! Really fast. The only problem I had was to get all the redirects to work. And I also removed my gallery2 installation and moved the blog to / ...
