Perceptual Image Compression at Flickr |

by sbrothier & 1 other
At Flickr our users really care about image quality.  They also care a lot about how responsive our apps are.  Addressing both of these concerns simultaneously is challenging;  higher quality images have larger file sizes and are slower to transfer.   Slow transfers are especially noticeable on mobile devices.   Flickr had historically aimed for high quality at the expense of larger files, but in late 2014 we implemented a method to both maintain image quality and decrease the byte-size of the images we serve to users.   As image appearance is very important to our users,  we performed an extensive user test before rolling this change out.   Here’s how we did it.

Apartheid in South Africa : un album sur Flickr

by sbrothier
Apartheid became the official policy of the Government of South Africa in 1948, following the election of the Herenigde Nasionale Party, later renamed the National Party. Under this policy, racial discrimination was institutionalized. The lives of the Africans, who made up almost 75 per cent of the population, were controlled by the unjust segregation laws from birth to the grave. They were proscribed where to live, who to marry and the type of education they would receive in the country of their birth.

Flickr Officially Comes to the iPhone

by sbrothier
iPhone is the most popular camera on Flickr, but Flickr (Flickr) hasn’t really returned the love to iPhone users…until now. Because, you know, having your website optimized for the iPhone is one thing, and having a full fledged, native application for the platform is another.

20th Century Remembrances : un album sur Flickr

by sbrothier
Yet more of the Weird, sometimes funny, sometimes sad but decidedly interesting slides of the 20th Century. All of them were up for grabs at estate sales or garage sales or in the trash, their owners long gone. So I came to the rescue with my trusty scanner and Photoshop. Some of the slides had labels and others needed labels. I provide song lyrics when inspired. Leave your thoughts - that's why I've posted them...
