Common telecomunications network: open, free and neutral
This is the purpose of Guifi.net, a place where there are so many interconnected routers, lines and individuals sharing their network with a clear purpose: open, free and neutral.
You can see a map where you will see how extended the network is:
In Sevilla there is a cooperative working under the same principles: SevillaGuifi.net
This is a 1 hour video, that talks about life, being professional, and security.
I enjoyed it a lot, and I would like to save the link,
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.
I love this type of maps:
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.
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.
Based on a SAP platform, some basic lessons I learned about retail.
- 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.
- 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.
- 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.
