programming logic algorithms computer science and programming puzzles programming logic algorithms computer science and programming puzzles running heroku apps locally on port 80 with facebook connect suppose you are hosting your app on heroku or some similar provider and you rely on facebook connect for user authentication how do you run your app locally so that you can develop and test without messing with the live version using a third party api like facebook connect makes it tricky because you need this entry was posted in heroku javascript on october 9 2017 by daniel scocco mongodb and node js timezone problems with date objects when you start working with node mongodb you probably will resort to the native date object to play around with and store dates i did it too only to discover that you will face a lot of timezone related problems if you do that mongodb stores dates on the utc timezone as default but your node this entry was posted in javascript on october 9 2017 by daniel scocco list of basic ffmpeg commands lately i have been working on a hobby programming project that automatically converts text or web pages into videos many functionalities of the software come from an open source project called ffmpeg it is great for working with video and images below you will find the commands and annotations i made over the past few this entry was posted in linux on

mongodb mongodb mongodb tutorial cloud mongodb service mlab toarray in mongodb node js express je html to jade pug converter bcrypt module usage social authentication with passport this entry was posted in javascript on november 13 2016 by daniel scocco event driven programming with node js lately i have been playing a lot with node js and event driven programming and several gotcha moments occurred below you ll find of them event driven programming as the name implies a programming paradigm where the flow of the program is governed by events there is a main loop monitoring things and triggering the appropriate callbacks noje js contrary this entry was posted in javascript on october 8 2016 by daniel scocco how to deploy a node js app to heroku below you ll find the basic steps to deploy a node js should apply to other languages and frameworks as well on heroku it assumes you have git and heroku toolbelt installed you can view a more detailed tutorial here 1 create the app locally you can view a hello world example here 2 git init 3 this entry was posted in heroku javascript on september 8 2016 by daniel scocco git basic commands git is one of the most popular version control systems out there below you ll find the basic commands you need to get started with it note one important aspect to understand about git is that it thinks about data as snapshots of files over time every commit will generate a new snapshot that is independent this entry was posted in tools on september 7 2016 by daniel scocco facebook webhook integration code in php many types of applications that interact with facebook will need to use webhooks messenger chat bots are an example if you follow facebook s setup guide you ll notice that the example provided to activate a webhook for the first time is in node js app get webhook function req res if req query hub verify_token your_verify_token res send req query hub challenge else this entry was posted in php on september 7 2016

origin policy a rule used to make sure that a malicious script won t be able to access data on other pages this can be a problem however if you need to load data for a this entry was posted in javascript on september 3 2016 by daniel scocco modern javascript development it looks like javascript is taking the crown from ruby for modern web development i never used it in the backend so i was curious to research about the libraries and frameworks that the cool kids are using these days here are some of them node js event driven runtime environment for developing server side applications
