Here's the situation : With Heroku & Postgres, you can have automatically generated backups dump file. But what can you do with it? Dump it on your database, if you want to fully go back to the backup state Dump it locally to "have a look", or to use production data in development environment Set back specific rows of your database in a previous state (eg. restore accidentally deleted rows) I found myself so much struggling about latter point that I wanted to share how I have done it. How to restore specific data from previous backup on Postgres Heroku? Augustin Riedinger Summary / TL;DR In 3

I'm trying to begin developing a skill for alexa using flask-ask and ngrok in python. Following is my code: from flask import Flask from flask_ask import Ask, statement, question, session import json import requests import time import unidecode app = Flask(__name__) ask = Ask(app, "/reddit_reader") def get_headlines(): titles = 'is this working' return titles @app.route('/') def homepage(): return "hi there, how ya doin?" @ask.launch def start_skill(): welcome_message = 'Hello there, would you like the news?' return question(welcome_message) @ask.intent("YesIntent") def share_headlines():

I'm trying to install ngrok (which I've been using for a while on Windows with no issues) on my 1 week old yosemite and these are the steps I've followed so far. 1. Downloaded ngrok from here https://ngrok.com/download . 2. Unziped the file and copied the Unix Executable File into application. Now from what I understand I just need to open the terminal, move inside the application folder and write ngrok http 80 . The

When I try to use ngrok I can't visit the address I'm given, i.e: ngrok http 5000 is what I'm putting in the command line, and it's returning this: ngrok by @inconshreveable Session Status online Version 2.1.18 Region United States (us) Web Interface http://127.0.0.1:4040 Forwarding http://ea986ca5.ngrok.io -> localhost:5000 Forwarding https://ea986ca5.ngrok.io -> localhost:5000 Connections ttl opn rt1 rt5 p50 p90 0 0 0.00 0.00 0.00 0

如果没有公网ip的话，外网与内网的计算机节点连接通信时，需要能够顺利的进入到内网，为了实现这个过程，有很多现成的技术，比如ngrok，花生壳，零遁，vps，虚拟局域网，等等。表面看起来实现的是同一个功能，但是细节上差别还是很大的。 首先ngrok呢，是一种软件，是做的一个反向代理，通过在公共的端点和本地运行的 Web 服务器之间建立一个安全的通道。类似ngrok的软件还有很多的，它们主要用于在本地建网站来让外网访问到，由于软件是国外的，所以目前能接触到的都是国内的代理，所以适合用来建小网站。 在这里，笔者不对各种工具的价格做对比，仅对功能的区别做说明对比，以帮助有需要的人选择合适的工具。 Vps就是租用服务器，它能够使用户通过服务商的公网ip发布本地web服务，这一点使得它和ngrok的实现方式完全不同，在带宽、传输协议和端口转发数上有了更多选择，而且有些高防服务器还能抵御网络×××，这使它适合用来建较大的网站或者站群。 前两者是将内网曝光到公网，公网上的游客都能访问到，虚拟局域网是实现特定局域网之间的访问，也就是点对点的通信，它主要实现的是异地传输文件数据，远程办公，外网访问内网的数据库服务器、ERP服务器等，它更适合特定人群内部使用。 花生壳和零遁的适应性更强，不仅能实现广泛人群的内网访问，同时也能实现特定人群的内网访问，在功能实现上较为相似，在技术上有所不同，前者了解的人很多
