Free encryption for Node.js on IBM i

Let's EncryptWhen you browse a secure web site or API whose address starts with “https,” what makes the site secure? The site uses a special certificate, provided by a trusted Certificate Authority (CA), to prove that it is legitimate. Until recently, IT shops had to pay for these certificates and generate them manually.

In the last few years, Let’s Encrypt has earned the thanks of technology professionals. Let’s Encrypt, a CA run for the public’s benefit, offers certificates at no charge, along with scripts to generate and regenerate certificates as needed, reducing the effort of keeping certificates up to date, and keeping sites secure.

State Sales Tax Ruling Spurs IBM i Integration

IBM i integrationIBM i integration via APIs has been central to many of our development projects, especially those involving web/mobile applications, software-as-a-service (SaaS) solutions, and cross-platform data sharing.

Lately we’ve been helping customers prepare for new state sales tax rules on internet sales by integrating APIs with their IBM i systems.

Db2, SQL, and Open Source Languages on IBM i

db2 sql open source ibmiPresentation Handout

The ever-expanding capabilities of Db2 for i can simplify development in open source languages such as PHP, Ruby, Node.js (JavaScript), and Python. These languages, known for their effectiveness in building web and mobile applications, can tap into the power of SQL.

So why complicate them with repetitive code that distracts from their power and simplicity?

Configure IBM i Apache Threads For Higher Traffic

When your site gets busy, your web server may need a configuration change to handle the load. We often start with the Apache web server’s ThreadsPerChild directive.

ThreadsPerChild controls how many connections can exist at once. Defaulting to 40, its value can be set in your Apache instance configuration file (for example, /www/zendphp7/httpd.conf):

Collaboration at COMMON

The 2015 COMMON annual meeting and expo, now in its first day, is helping speakers and attendees create innovation through IBM i integration: open source, closed source, IBM and vendor solutions. For example, of my six presentations during this conference, two are collaborations:

The Art of Performance Diagnostics, with IBM’s Dawn May, allows us to show, among other topics, how IBM i’s integrated performance tools complement green-screen tools and third-party tools (in this case, Zend Server) to pinpoint and solve performance issues (here, PHP-and DB2-based applications).

PHP Tricks for RPG Developers, a talk jointly created by RPG and SQL expert Birgitta Hauser and me, combines RPG, PHP, and DB2, allowing RPG to achieve graphical (charts and graphs, PDF and Excel files) and internet (json-based web services, flexible email) functionality using native functions.

Conferences such as COMMON serve a need that’s difficult to replicate back at the office—brainstorming and sharing possibilities among interdisciplinary peers, or sitting side-by-side with like-minded colleagues who work for different employers, to try something new. This week, for example, some of us plan to share knowledge on compiling binaries in PASE and to further the potential of open source on IBM i. I’m looking forward to presenting my talks (both joint and solo) and helping to realize new ideas with forward-looking colleagues during the conference.
