Programmer’s Backdoor Trap - Ran Wahle's blog(blogs.microsoft.co.il)

submitted by ranwranw(263) 3 months, 27 days ago

Today I’ve encountered something that made a programmer happy but made me sad. He had to pull data out of Data Warehouse and use it for his system. Later, he was informed that DWH personnel made his life easy: They’ve decided to write the data into his own database so he wouldn’t have to work so hard.

Internet Explorer 8 (and below) won’t show some of your jpegs(blogs.microsoft.co.il)

submitted by ranwranw(263) 8 months, 27 days ago

A very strange phenomenon I came across while developing web application for a customer. A Jpeg formatted picture wasn’t shown on IE8 browsers, while shown on others (Firefox 5, Chrome 12, IE9). The browser displayed an empty placeholder with a red ‘X’ as it does when not finding an image. This led as to searching for causes such as wrong URL, communication problems etc. . read more...
