Deploying Yamz on my machine!

Last week has been a tough week for me. I had been working closely with Bridget and John to set up a local yamz environment on my machine. Both John and Bridget are super helpful and very experienced in software developing and problem-solving. I asked John a question since started to read the readme document: what does the ‘xxx’ mark in the readme file stand for? I noticed a lot of ‘xxx’ marks in the Readme document of yamz.net (https://github.com/vphill/yamz), for instance, there are a couple of blocks start with the mark of ‘xxx’, such as:


xxx do this in a separate “local_deploy” dir?

xxx user = reader?


I was really interested in what does those line mean. Based on my experience with yamz, most of the lines started with ‘xxx’ is pretty useful and definitely something worth to read in the first place. John said in the world of software development, ‘xxx’ mark stands for problem waiting to be solved or comments so critical that should be paid attention to immediately. It seems my intuition was right but it is also confusing to those people without developing experience. We are going to rewrite the readme file in the summer to make it more reader-friendly. Meanwhile, I’m still debugging some error I’ve encountered while developing:






According to Margaret Rouse (see the link below), OAuth “allows an end user’s account information to be used by third-party services, such as Facebook, without exposing the user’s password”. The central idea of OAuth is to reduce the total number of times password is required in order to establish an identity, and instead to ask trusted parties to issue certificates for security and convenience concerns. But it also raises a question of to what extent we trust Google, Facebook or Twitter, and etc. as a gatekeeper for our personal identity? What is the price we are paying to use their service in lieu of money?  Will it stop at ‘we run ads’?
