Guru99, python and more

There are so many tutorials about almost everything, this time I found this one: https://www.guru99.com

  • Guru99 Vision: Fun & Free Education for ALL
  • Guru99 Mission: To bring all feasible courses , online.

Python was the one who took the first look, but I went quickly to other tutorials.

I am inmersed now on a SAP HCM project, so I have read the basis of the SAP Infotype organization and other relevant stuff that the consultants are mentioning every single day.

Read tutorials is hard, but these ones are in real “plain english” so you quickly understand the topics. They are focused on people without knowledge of a topic.

Lingvist

I have started to use Lingvist to improve my french. I have to improve all aspects of my french and the most important one is the writing skills. The exercises proposed are fine to improve the writing skills.

The proposed platform contains elements of gamification where you can measure your results, time invested, etc. I miss that for reading and listening content the platform does not offer exercises to check your level of understanding or listening so you can also track that evolution.

ServiceNow Training Vs SalesForce Trailhead

I have accessed to the ServiceNow training services they offer. And as I have been using the SalesForce Trailhead services, to compare it is the first thing I have done.

The first thing you find is that the majority of the courses are so much expensive. You can consider that nothing is for free, but the amount of training courses offered by SalesForce is impressive.

The user interface is very classical in comparison with trailhead. The use of videos is low and there is a lot of documentation to read, but without a clear learning path or goal.

The way the information is updated it nice but you have the feeling you are accessing to a help database from 2002.

It’s clear the training strategy from ServiceNow is so much different to the one picked by SalesForce. I’m sure they are making some money with these training courses, but the speed of adoption of the communitty (technical, users and business users) is going to grow very slowly in comparison with SalesForce.

Retail, some basic lessons I learned

Based on a SAP platform, some basic lessons I learned about retail.

The stores:

  • The POS are terminals that retrieve data from a server, typically located on the same store.
  • The server of the store receives/sends data to a SAP PI.
  • The frequency of these communications depends on your capacity to manage big volumes of data.
  • The technology on the store can be independent to SAP. SAP PI will send the appropriate data format.

ERP

  • The Origin of all data comes from ERP, specially from SAP SD (sales & distribution).
  • SAP Retail will gather the detailed data that goes and come to the POS servers.
  • SAP Retail have all detailed data. The quality and the granularity of the data will determine the ability to posterior data mining actions.
  • Typical problems of SAP Retail are: communications, and reporting (have the ability to gather the required data in terms of volume or detail).
  • The management of promotions and affiliations is other major topic on the processes.
  • To simplify the data complexity, SAP Retail sends the data to SAP SD taking into account that each store is a single customer.
  • Affiliated people can be on a CRM or on SAP SD.
  • SAP PI sends/receives data and transforms it into the right formats. This enable the integration with different POS vendors.

Data mining:

  • For high levels of detailed data: retrieve it from SAP Retail. SAP HANA is not enough for handling big volumes of data. Hadoop is the preferable solution for these big volumes.
  • For detailed data: retrieve it from SAP SD.
  • For generic data: retrieve it from SAP FICO.
  • A serious BW retrieves data from SAP Retail.

Real time & transactions:

  • Frequency of transactions between POS and SAP can be complex when you have so many terminals.
  • The need to increase this frequency can stress the architecture and force changes at that level.
  • The demand of data miners and the need to act on prices at the end of the day depending on the consumption trends can be something complex if the architecture is not well implemented.
  • Majority of transactions are done during the night, but it could be different.

Trailhead, continuous evolution

I completed some trails of SalesForce Trailhead. Now I come back to make some new modules and I have found that some of the trails I did have included some new modules to enrich the knowledge of the trail.

For instance on the developer beginner there is a new module for search engine, where you learn about:

  • Salesforce Object Search Language (SOSL) and other aspects of search.
  • How to refine a search and have a balance between data offered and time response.
  • How to include auto-suggest on searchs.
  • How admins can promote a maximum of 2000 terms.

Once completed you have again completed the trail, with more points: from 19225 to 19525.

Discovering Kik

I have been reviewing Kik, specially the ability to create your own bot.

You interact with the development environment through a bot that adds you into the development environment and that guides you about the next steps you can perform to create a bot and a bot user.

It is interesting to see the bot store, and discover the maturity of the community.

It’s interesting to review the code of a basic bot, and review the kikAPI.

I learned that WhatsApp is against the creation of bots in its platform. So, they did their best to avoid any bots in their platform. If you manage to create a bot for WhatsApp, then it violates the WhatsApp terms and conditions. When WhatsApp is aware of your bot, the corresponding mobile number will be banned from WhatsApp and make your whole effort useless. WhatsApp is planning to support business through business accounts in middle 2016.

SalesForce Trailhead Developer Beginner

During these last 7 days I have been using my free time to complete the Developer Beginner training from SalesForce.

I have worked in Lotus Domino world during some years and so much of the concepts implemented in SalesForce have the same vision of Lotus Notes; the difference is for sure there are 20 years difference in the technology to implement that vision.

The similarities in the concepts with Lotus Notes made me to go quickly on the training sessions. The most useful part are the challenges and the code you can test at the same time you read the lesson. The usability and the way to acquire concepts is so good, the timing of 20 – 25 minutes is also good.

Do I recommend to go through this training? yes and no.

  • If you want to understand the basic concepts of the SalesForce platform and understand how powerful it is, YES.
  • If you loved Lotus Domino and miss to work on a platform as that, YES.
  • If you are a pure programmer that comes from Java, .NET world, you probably will find it boring, so NO.
  • If you find corporate workflows and business process boring, NO.

SFDC-Trailhead-Developer-Beginner I will go through other one during Christmas time, Which one do you recommend me?
