• Neccessity of push and pop operands on CPUs

  - by Hawken

  Why do we have commands like push and pop? From what I understand pop and push are basically the same as doing a (mov then add) and (sub then mov) on esp respectively. For example wouldn't: pushl %eax be equivalent to: subl $4, %esp movl %eax, (%esp-4) please correct me if stack access is not (%esp-4), I'm still learning assembly The only true benefit I can see is if doing both operation simultaneously offers some advantage; however I don't see how it could.

• Application self aware of external database record modifications.

  - by Khou

  How do you make your application aware that a database record was changed or created by an external application rather than the application itself? Do you add a special check sum to the database record or what do you do to stop external changes to the database? (in case it was hacked and the hacker decides to add a new record or change an existing database record)

• Running cUrl cmd from Win7 doesn't work, but on Linux it does.

  - by jkidv

  Like the title says. I'm sending a simple cUrl cmd from Win7 to CouchDB on my Linux box, and it doesn't work. But if I run the same command in Linux, it works. I'm sending this: curl -X POST 192.168.2.5:5984/test/testdoc -d '{"owner":{"fname":"test","lname":"ing"}}' From windows, it keeps giving me a "error: bad request, reason:invalid UTF-8 JSON". I can run GET commands from windows just fine, I just can't seem to POST to CouchDB.

• What the guidelines around filters and querystring parameters in RSS Feeds?

  I run a site where users can content that is tagged by a special set of tags. While implementing RSS feeds, I was wondering what, if any, rules or guidelines exist for using a querystring to filter what content an RSS feed shows.

  - by Morgan Cheng

  I happens to find that, when a live space page is loaded, inline images are fetched by https protocol instead of http protocol. This doesn't make sense. The text part of live space is not fetched by https, why images are fetched with https? I bet the https way to fetch image just make the page loaded slower. Is there any special advantage to choose https over http in this case?
