Modern hardware relies primarily on memory mapped I/O which is typically at addresses that are not mapped by the kernels initial page tables, which makes using them currently unusable for early debugging print support. So this patch set digs in and fixes the early page tables on both arch/i386 and arch/x86_64 so that set_fixmap works with our initial boot page tables. All that is needed is that

I am trying out ROR for the first time[1], and have much PHP poisoning to overcome in my mental baggage. That said, I was delighted to find that I could make a link from a "show" page to the next record in the database by simply adding @next_page = Content.find(params["id"].next) to my content_controller.rb and then constructing a link to it within my show.rhtml. The only definition of the ''next'' method I can find is within the ''paginator'' class, yet I am not invoking that class as far as I...

Recently, I got many reports about perfermance degradation in embedded system(Android mobile phone, webOS TV and so on) and failed to fork easily. The problem was fragmentation caused by zram and GPU driver pages. Their pages cannot be migrated so compaction cannot work well, either so reclaimer ends up shrinking all of working set pages. It made system very slow and even to fail to fork easily.

Hi: I am looking for a good hands on web mashup tutorial? or books for that matter.. Google gives me bits and pieces of the info but not any step by step or hands on tutorial..
