Apple Is Trying to Kill Web Technology
- 06 Dec, 2020
The programming languages used to build the web often find their way into apps, too. That’s largely due to software that allows developers to “reuse” the code they write for the web in products they build to run on operating systems like Linux, Android, Windows, and macOS.

Apple Is Trying to Kill Web TechnologyRead MoreConfiguring Cross Origin Resource Sharing on a Liberty server
- 08 Mar, 2018
You can enable Cross Origin Resource Sharing (CORS) for your web applications on a Liberty server. Enabling CORS will allow JavaScript clients to make requests against your application on the Liberty server even if the client and the server are on two different domains. Web browsers prevent these requests due to same-origin policy. I create the following configuration on my local machine on server.xml file:

- 16 May, 2016
Flash's death has been slow and painful, and now Google is planning to deal it another blow. Google has detailed plans to start blocking most Flash content with Chrome, with the change targeted toward the end of this year. Under its current vision, nearly every website would have Flash content blocked by default. Visitors would still be able to enable Flash content on a site-by-site basis, but they would have to specifically choose to do so. Chrome would display a prompt offering to enable Flash; if chosen, Chrome would remember to run Flash on that site for all future visits. See the full article here(http://www.theverge.com/2016/5/15/11679394/chrome-to-block-flash-later-2016)

- 21 Sep, 2016
Working this week on a new WebSphere Portal Project. Several content are using AngularJS and some calls to get data go to another server in another domain. To avoid CORS(https://en.wikipedia.org/wiki/Cross-originresourcesharing) we implement a reverse proxy on the IHS side. Bellow the config of my httpd.conf. LoadModule proxy\module modules/mod\proxy.so LoadModule proxy\connect\module modules/mod\proxy\connect.so LoadModule proxy\http\module modules/mod\proxy\http.so LoadModule ibm\ssl\module modules/mod\ibm\ssl.so SSLProxyEngine on KeyFile /opt/IBM/HTTPServer/bin/key.kdb SSLStashfile /opt/IBM/HTTPServer/bin/key.sth Proxypass /acme/products https://anotherdomain/api/v1/products Proxypa

- 11 Jun, 2020
I am creating a server (Centos 8) to develop a system that will use an application using REACT as a front end to show data from different sensors.I will use NGINX as a webserver and Node-red as a back end.In this first post I describe how to install NGINX. Install nginx package using the yum command on CentOS 8: sudo yum update sudo yum install nginx Update firewall settings and open TCP port 80 and 443. Run: sudo firewall-cmd --permanent --zone=public --add-service=https --add-service=http sudo firewall-cmd --reload Enable nginx service by running systemctl command so that it starts at server boot time: sudo systemctl enable nginx start the service, run: sudo systemctl start nginx

- 29 Dec, 2009
We are migrating an installation of Portal 6.0.1.3 to 6.1.0.1. After several errors and corrections applied is time to finalize and put the last piece of IBM HTTP Server. But the Bug described in this TN(http://www-01.ibm.com/support/docview.wss?rs=688&context=SSHRKX&context=SS3JLV&context=SS3NNG&context=SSYJ99&context=SSRUWN&context=SS6JVW&q1=1411193&uid=swg21411193&loc=enUS&cs=utf-8&lang=en) seems to be the last headache. Beware of remote HTTP Server and Portal 6.1.x

You need A Fully Qualified Domain Name (FQDN) pointing to a dedicated IP address of the webserver. This needs to be configured by your DNS administrator or provider. 1 - Install Certbot in Centos 8 sudo curl -O https://dl.eff.org/certbot-auto chmod 0755 /usr/local/bin/certbot-auto 2 - Configure Nginx server\name on nginx.conf Edit nginx.conf an change the variable server\name to the same FQDN of your server for example: server\name www.mysphere.com.br; 3 - Run the certbot command: Execute sudo /usr/local/bin/certbot-auto --nginx and follow the instructions Test if your Nginx server using https://

Setup a Node.js development environment is easy but when you need to work in a team, the best option is document all installation steps for everyone. Every developer must use the same setup or things can be wrong. Bellow are small steps to setup a simple Node.js development environment 1 - Setup Node.js: https://nodejs.org/en/(https://nodejs.org/en/) 2 - Setup VS Code: https://code.visualstudio.com/docs/setup/setup-overview(https://code.visualstudio.com/docs/setup/setup-overview) 3 - Open VS Code create a folder and in this folder save an file as app.js 4 - Setup nodemon: Nodemon is a utility that will monitor for any changes in your source and automatically restart your server.
