Json il less verbose and is the de facto standard for the web, json is easier to parse by javascript (by the browser or node.js), and a serialization/deseriazation is unique, in xml you could put some infos on the attributes oand other on tags or as parameters. instead of <event name="gamma_size"> <arg name="size" type="uint"/> </event>

{"type":"event", "name":"gamma_size", "arg": {"name":"size","type":"uint" }

Re:Google: My interview experience on Sunday April 23, 2017 @08:54PM (#14181280)
My experience: I applied for an open position at google on their website, during the university, an interview was arranged after some mails, I was positively surprised by their care of detail: about setting the inteview at right time during the day for me, wow!. When I recieved the call i was suprised, but because call me at wrong day, at wrong time, It was on dinner on my time, and I drinked a couple of beer, it was stressful, the interview was difficult and unsuccessful, after a couple of days by mail told that inteview was not successful. I'm from italy, here the company adopt the Hollywood Principle: “don’t call us, we’ll call you”, because there are too much applicants and few good jobs. I digested: maybe I'm not good for the position, but also them are not perfect, but at least they try to be gentle. After a two of year I recived a mail for an interview, I was suprised because I did not solicitate it, I was very relaxed because I was discard the previous time, so why this time should be different? (I'm fine that better developer exist), the interview seem goes easily, at the end interviewer ask me where I'd like to work if I could decide and describe some offices on google on different coutry, It was too exciting to be true, and replied all are the same for me, but why you call me, on the other interview I was discarded, he was suprised, told some 0info and asked some info on precedent inverview. Also this time I was informed by mail that the interview was not successful. Lesson 2: I thinked they call me by error, so two mistake in two interview:. nobody is perfect.
Re:A Constructive Look at TempleOS (2015) on Sunday March 26, 2017 @04:54PM (#13963233)
In other words templeos is a unikernel with a jit compiler. The name is odd, the author is strange, do you judge a movie by private life of the authors? The illness of van gogh, Gödel didn't affect their creations. missing graphical interface is a defect. An unikernal is a strange beast, sound crazy, but got some advantages: is simpler, could be understood completely by a human (and not only by a genius), there are no penality for system calls, and there is no cpu time wasted on context switch. Because the machine are getting cheaper is common to have only one user, so all these security became useless, so on the long run the unikernels will be mainstream. Kudos to him. a relevant discussion about unikernel here: https://news.ycombinator.com/item?id=10362897
On the photo #4 you can see a man pointing a pretty insecure computer, windows xp :) Should Not be used xp anymore because there is no more security updates or I'm wrong?

Single page application for donating stuff

Hi I wrote a single page application using Angular v.1 and openStreetMap, to reduce the latency I used template inline, the current cheap hosting don't me use a pre gzipped html page ( it could save 800Kb), so the first loading is slow, the further loading are fast because is mostly a single file application (fontAwesome excluded).www.ReteRegalo.com connects people who want to donating unused...
