Raspberrypi : Step-by-Step Static IP Configuration

Working with Raspberry PI (RPI) is fun. If you do not want to directly plug your monitor and keyboard always to your RPI, then you need to configure Static IP on the RPI. Typically in home environment, you will connect your RPI to your router and then need to control the RPI from your PC using SSH. In a router with DHCP enabled, you need to have static IP for your RPI so that IP will not be changed even router is restarted. Following instructions will show how to set up your RPI with static IP.

Requirement:
RPI is loaded with Raspbian and complete the initial setup.
Monitor and Keyboard connected to RPI

Configuration Steps (Single Network)

Open network configuration file using following command
sudo nano /etc/network/interfaces

Update network configuration file as below.

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 192.168.123.101
netmask 255.255.255.0

gateway 192.168.123.254

Save the file by pressing "CTRL+O" and exit editor by "CTRL+X"

Then restart the RPI in order to reflect these changes using following command
sudo reboot

Configuration Steps (Multiple Networks)

If you have multiple network connections like Ethernet and Wifi, then static configurations should be in the last part of the network configuration file as shown below. In your static IP configuration remember to add "one tab space" for the config items of the eth0 as shown below.

auto lo
iface lo inet loopback

 auto wlan0
allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp

auto eth0
iface eth0 inet static
   address 192.168.123.101
   netmask 255.255.255.0
   gateway 192.168.123.254


NOTE
You can configure your router to assign same IP by adding a rule in your router configurations by using the MAC address of the RPI.

Embedding PowerBI with ASP.NET Core 2 and Angular(2,4,5)

Image
Background  Integration of PowerBI into ASP.Net is straightforward as far as you follow the Microsoft documentation. When it comes to ASP.NET Core 2, it is not, at the time of writing this article. Let me guide you through the steps I followed to successfully embed PowerBI reports to our ASP.NET Core2 / Angular5 enterprise website. Two Scenarios 1. User Owns Data - where users will be directly registered in PowerBi portal https://docs.microsoft.com/en-us/power-bi/developer/integrate-report 2. App Owns Data - you have an application which owns the data and you have users to view these reports but they are not registered in PowerBI as direct users - ISV situation https://docs.microsoft.com/en-us/power-bi/developer/embed-sample-for-customers Following steps are focused on scenario 2 which is app own data, but it is not limited to use this information for scenario 1 as well. [Flow of authentication and authorization (from Microsoft documentation)] Step 1: Regis

CSS text-overflow ellipsis in the beginning of the the text - Left Ellipsis using CSS in a Flex box

Image
Problem: If you want to have css text overflow ellipsis in the left (beginning of the text), there is no straight forward solution to get it working in all browsers (especially in Safari). There are several CSS tricks that you will end up only working few browsers. It will be further difficult, if you are trying to achieve this in flex container. Solution: Combining few ideas found in the stack-overflow, manged to get it working in most of the browsers including safari. ".cont" is flex box and either you can set a width to it, or can inherit the width from parent container element. .ellipsis:after { content: ""; background-color: white; color: transparent; position: relative; z-index: 2; min-width: 100%; display: inline-block; min-height: 1rem; } .ellipsis { direction: rtl; display: inline-block; width: calc(100% - .1em); white-space: nowrap; overflow: h

Selenium With .Net

Recently I had a chance to work with Selenium framwork. It is pretty easy to intrgrate automated testing into .net with Selenium. Also for project like web site scrapping and automated posting, can be easily developped with few lines of code. Following code lines will automate a web site login with use of selenium framework. ISelenium selenium = new DefaultSelenium(seleniumServer, port, browser, website); selenium.Start(); selenium.Open(ConfigLoader.Configurations.LoginPageUrl); selenium.WaitForPageToLoad((ConfigLoader.Configurations.WaitingTime * 1000).ToString()); selenium.Type("ctl00_PageContent_UserName", ConfigLoader.Configurations.UserName); selenium.Type("ctl00_PageContent_Password", ConfigLoader.Configurations.Password); selenium.Click("ctl00_PageContent_OKButton__Button"); selenium.WaitForPageToLoad((ConfigLoader.Configurations.WaitingTime * 1000).ToString());
