I have gotten to setting UP a Flask environment for a project recently. Was completely puzzled by how to run this. I have used to running Django project with python manage.py script. This means pointing out a PyCharm interpreter into a certain point of entry, that is also a .py file also. In flask way of starting things there is another approach however. Here it is in Flask Docs. It states to set a variable FLASK_APP and then run a flask run command. This will confuse running a python script way of a project being run. Thus to fix this one needs to set a path to flask binary file. It usually is within a virtual environment binary directory, place where your python interpreter resides. So to set debugging one needs to set path to script binary one needs: Script: /path/to/env/bin/flask Script parameters: run   Environment variable  FLASK_APP=app.py Environment variable FLASK_DEBUG=True Set working directory back to your app path (It changes automatically according t...

I have had some tasks to configure and install a CentOS distribution for my bug-tracking needs. Hope to help out someone with similar problems and or tasks. I'll be using a fresh install of a CentOS Minimal 6.5.  And a Mac Book Pro with VirtualBox installed (as my testing environment). First after install of a clean CentOS you need an SSH server to work in your usual environment. So to connect to a Linux, installed in a VirtualBox you will need basically 2 things: openssh-server install disable firewall VirtualBox Port configuration/Access configuration OpenSSH server install To install server you need to run in your VirtualBox Guest system (CentOS VM): yum -y install openssh-server And start and add it to auto launch at system startup: chkconfig sshd on service sshd start Also make sure port 22 is opened in your VM. type: netstat -tulpn | grep :22 Firewall settings Because it's a VM you can simply disable the firewall. But be sure not to do this a...

Here are my first steps. And I hope you will find something useful here, while configuring your Pi... First of all. Mine have been bought on ebay, from resellers. And were delivered a while ago. Main purpose of this purchase war to attach a headless server to my router. I have 2 external HDD's and would like to have torrents, Time Mashine fro my macs and so on. So buying a handheld computer like this would be a bargain for me. As for built in decisions like some kinds of NAT devices and different routers with external HDD features... They are either cost a lot or lack some kinds of desired functionality. So the goal is to make some kind http/api manageable server in my local network with Time Mashine and file storage/backup. Just for fun. And to have only laptop on my work table. SO back to the Pi. If you are buying "device only" configuration, like I did. First of all you'll need some different kind of things many computer fans usual...

Prologue Hi! Let's talk about Django ways to code. First you have to have environment installed for work with Django. Today I'll try to show you my way of using virtual environment ( python virtualenv ). It's ok to handle package dependencies in Django apps by simply manually putting libraries, are in need for your project, into project PYTHONPATH. It's an easy way to do it. BUT what if you would like to make another project with this environment (e.g. the same modules, plugins or app's set)... You will have to add all those modules to your new project. Another issue that if would like to code for existing project, like for e.g. open someone's work and add some modules to it.  Virtualenv is a newly fashioned package which aims to combine the best features of a workingenv with a virtual Python install . Also you can say that it is a tool to create isolated in a sandbox Python environments. So... This article is about how to set up, run and conn...
