The bus ticket theory of genius

paschmann

Source: http://paulgraham.com/genius.html

Everyone knows that to do great work you need both natural ability and determination. But there’s a third ingredient that’s not as well understood: an obsessive interest in a particular topic.

To explain this point I need to burn my reputation with some group of people, and I’m going to choose bus ticket collectors. There are people who collect old bus tickets. Like many collectors, they have an obsessive interest in the minutiae of what they collect. They can keep track of distinctions between different types of bus tickets that would be hard for the rest of us to remember. Because we don’t care enough. What’s the point of spending so much time thinking about old bus tickets? read more

Did you know? Money Remittance

paschmann

Blockchain could improve life for millions of immigrants who suffer exploitation when they send money home to their relatives. Western Union, MoneyGram and other intermediaries have a monopoly on the movement of money, collecting $38 billion annually in remittance fees. Fees can run as high as 20% and most of the people who pay them are low-wage workers.

GSVU Student Presentation

Mentoring, coaching and sharing is an opportunity I am always willing to go the extra mile for. When one of my friends Sihma from Grand Valley State University (a fellow SAP mentor and part of the SAP University Alliance Program) asked me to do a personal presentation for their Computer Science students, I took a untraditional approach and shared the presentation below.

Hacking SAP HANA Websockets

paschmann

Disclaimer: This is not a production or documented feature – its also more of a hijack than a hack  🙂 

I have been hoping for the inclusion of Websocket support on the HANA DB platform for a while now, and I was a little disappointed it was not packaged in the SPS08 release. My goal when building apps (or products) is to make use of the core platform its running on as much as possible, I firmly believe that when convincing an IT department, or company, to implement a product or app, the first question is: “How much infrastructure does this need?”. This can often be a deal breaker and why I am such a big proponent of the HANA’s DB + XS App Server integration – it consolidates the requirements into a single investment. Having a Websocket technology built directly in XS can be an additional selling point which developers are starting to expect these days. read more

Simple Sample: Writing an entry to SAP Netweaver Gateway using JSON

paschmann

Skill Level: Beginner

Time Needed: 20 minutes

I recently assisted someone on the forums when they were having trouble creating records in their SAP ECC instance while using Gateway. I thought I would share some very simple code showing what it takes to write an entry into a service via JSON from iOS (Objective C). The reason the title of the document is “Simple Sample” – there are no frills. Whenever I develop a new app, I start small, get the basic functionality working, and proof out the process before getting too creative.

*** If you do not have your own gateway server, you might be able to connect this to the SAP Gateway System which can be found here. Create an account and utilize this service *** DISCLAIMER: Untested as the signup form does not work 🙁  read more

2012 SAP TechEd and MOB205

paschmann

Well …. TechEd has passed and it was a great time. InnoJam was probably the best experience and I managed to be a part of a great collaboration which was fun from the start – I will blog a little about our solution in some of my free time in the coming weeks, but back to the topic at hand, since this was my first time as a speaker at TechEd I was slightly intimidated and anxious … my session was on Friday at 8:00AM, the night after the 3 Doors Down concert and I was skeptical if *anyone* would even show up 🙂 . The morning came, and to my surprise, the room was full and even had multiple people standing at the back. I was impressed so many people attended, and showed that my investment of time and resources into the enterprise mobility space over the last few years was worth the effort. The presentation went well and thankfully I had the “Demo Gods” on my side connecting from the Venetian (iPad) to Amazon Web Services (Gateway) to Walldorf (ES Workplace) and back 🙂 . After the presentation wrapped up I had great comments and questions from the audience but ran out of time answering all of them, I figured I would share the premise of the presentation here for everyone and hopefully encourage more companies to take a few easy steps to start their journey into the mobile enterprise. read more
