-

i got code https://github.com/ccoenraets/backbone-cellar trying learn backbone.js. when trying add new model database using slim.php, showing 500 (internal server error). when trying fetch, update, delete working good. why showing error on adding ?

plz me, thanks.

    window.wineview = backbone.view.extend({          initialize: function () {             this.render();         },          render: function () {             $(this.el).html(this.template(this.model.tojson()));             return this;         },          events: {             "click .save"   : "beforesave",             "click .delete" : "deletewine"          },          beforesave: function () {             var self = this;             var check = this.model.validateall();             if (check.isvalid === false) {                 utils.displayvalidationerrors(check.messages);                 return false;             }              // upload picture file if new file dropped in drop area             if (this.picturefile) {                 this.model.set("picture", this.picturefile.name);                 utils.uploadfile(this.picturefile,                     function () {                         self.savewine();                     }                 );             } else {                 this.savewine();             }             return false;         },          savewine: function () {             var self = this;             this.model.save(null, {                 success: function (model) {                     self.render();                     app.navigate('wines/' + model.id, false);                     utils.showalert('success!', 'wine saved successfully', 'alert-success');                 },                 error: function () {                     utils.showalert('error', 'an error occurred while trying add item', 'alert-error');                 }             });         },          deletewine: function () {             this.model.destroy({                 success: function () {                     alert('wine deleted successfully');                     window.history.back();                 }             });             return false;         }      });

i had same problem. in /tutorial/api directory; open index.php , first line in function addwine():

error_log('addwine\n', 3, '/var/tmp/php.log');

comment line:

//error_log('addwine\n', 3, '/var/tmp/php.log');

this should solve problem, did mine.

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
