Snippet to download a file using WinJS.xhr and save it. The file variable below is a StorageFile, result of pickSaveFileAsync. Note the usage of responseType: “blob” as an option to xhr, and how it is copied to the file stream with msDetachStream. 1 2 3 4 5 6 7 8 9 10 11 12 13 […]

PCH file built from a different branch ((clang-425.0.24)) than the compiler ((clang-425.0.27))

Atualizei o XCode da versão 4.6.0 para 4.6.01 e de repente meus projetos não construíam mais, dando o erro: PCH file built from a different branch ((clang-425.0.24)) than the compiler ((clang-425.0.27)) A solução foi simplesmente limpar o projeto. Vá ao menu “Product” e selecione “Clean”.

Powershell script to snap an app in Windows 8

You can not, from inside a Windows 8 application, snap it. That doesn’t mean there is no other way 🙂 At work, we have to test our app in a snapped state, so we need a way to programmatically make it happen. We discovered that there are two keyboard shortcuts for this action. Windows Key […]

Clojure script to parse IIS logs from a directory and show slowest pages

Just having some fun today. The code runs actually pretty fast: It reads over 1.5 million lines from 1.1GB of logs and sorts them by time-taken in 5 seconds. I bet there’s room for improvement but it was enough for my needs. 1 2 3 4 5 6 7 8 9 10 11 12 13 […]
