It is a long weekend with the president day on Monday. Which means it is another good opportunity to create more art. Whether that is a new ArcGIS pro Add-in or a new map, a painting, a new piece of poetry or music. This also means more chances to get discovered, which means more chances to get criticized. I get criticized all the time now that I have bigger exposure and this is our topic for this podcast coming up,  --- Support this podcast: https://anchor.fm/hnasr/support

This is originally a video that I converted into a podcast I think it is still useful  https://www.youtube.com/watch?v=8D1NAezC-Dk Notifications have become part of our daily life. We receive them almost every minute on our phones, tablets, and computers. As software engineers, it is good to understand how notifications work, and what different type of notifications there are (push and pull notifications), the advantages and disadvantages of each.    In this video I'll explain how the push notification and pull notification works and the stateful vs stateless nature of each and how it affects the architecture decision of our application that we are building.    Online diagram tool used in this video:  Http://www.gliffy.com   Become a better software engineer by joining IGeometry checkout the other software engineering content on this channel   -Hussein --- Support this podcast: https://anchor.fm/hnasr/support

Soap (Simple Object Access Protocol) has been a popular messaging protocol in the early 2000s. It uses XML as a format with well defined schema, and your choice of stransport protocol. Despite it still being used people have been moving towards #REST architecture and more so #gRPC recently. In this episode we discuss why people moved from #SOAP and what are the advantages and disadvantages of SOAP.   Stay Awesome! Hussein Nasser --- Support this podcast: https://anchor.fm/hnasr/support

In this episode we answer a question from Anthony. How do you know when to focus on building a geodatabase (let's say SQL server database) rather than just let the data sit in the shapefile? I would say if you are planning to have multiple users accessing and editing the data, also if your data grew too large shape files might not be scalable to read. Also if you are planning to use the capabilities of Geodatabase such as domains, subtypes, attribute rules, versioning, archiving etc not to mention sharing as well. if you wont plan to use any of the above then shape file is a good choice. If you are planning to just maintain a shape file data of 10k or 100k features and you edit it yourself locally it works!  --- Send in a voice message: https://anchor.fm/hnasr/message

When you publish a service you can specify how many processes (min / max) your service can use. As requests are being served memory is allocated, state is changed, some processes could go corrupt Recycling is the process destroying and re-spawning processes that are running to maintain a good memory footprint.  Here is a good read on recycling http://enterprise.arcgis.com/en/server/latest/publish-services/windows/tuning-and-configuring-services.htm Enjoy Hussein --- Send in a voice message: https://anchor.fm/hnasr/message

 I don’t have the equipments. There are people doing that already. And my personal favorite, I don’t know enough.  Excuses are always there, In this podcast I talk about my personal story of how I got started. You don't need fancy equipments to share your skills and knowledge. In this podcast we discuss how with just a screen sharing app (Quicktime) and this microphone I was able to grow my youtube software engineering channel to 2000 subs and more than 1 million watch hours.   --- Support this podcast: https://anchor.fm/hnasr/support

Vikrant asked a question on Linked:  Dear Hussein, I want to learn programming for GIS. Is python useful? I am not very good in programming. Kindly guide. And thanks for the posts.. Programming for GIS really depends on what you are trying to do and how do you want to advance your career. In this podcast we will discuss four kind of areas where you can programming for GIS.

If you ever go a website and there some images you liked to reference in your page or blog. You would copy the link, and put in your blog.  Only to find out that the image looks broken?  You copy the link again and paste it in URL and it opens fine?  This is an effect of CORS or cross origin resource sharing.  https://husseinnasser.com/courses --- Support this podcast: https://anchor.fm/hnasr/support

 ArcGIS Server is a technology that allows you to pull your heavy work load on the backend and isolate the clients from complexity of the database by exposing HTTP services instead of low level TCP database. You can also extend the server capability by writing your own extensions.  In this episode ArcGIS Server talk we will talk about two ways you can extend your ArcGIS server, Server Object Extensions and Server Object Interceptors. Server Object Extension  Extends the MapServer to allow you to write your own logic that cannot be easily done by built - in Feature Server or Map server. Or it is more performant to do it.   Users create new excavation I want to auto-calculate the price of the excavation based on the soil type, whether there are trees, rocks.  Server Object Interceptors  You don’t write new thing you instead intercept existing calls to query and applyEdits to inject your own logic to pre or post processing. Lets say every-time any application tries to write to the s

Any content served through HTTP “should” include meta data about its type. This is so the browser/client knows what to do with the content it receives. For example, if the content type header is an image the browser will preview it, if it is HTML it will render the markup and execute any javascript code. Content type however is optional and web masters sometimes don’t set it, which leave the browsers wondering about the content type it is consuming. So browsers had to implement parsing and “sniffing” techniques to detect the type of content when a content type header was not served. However, this caused security problems and attacks that we explain in this video! So to prevent sniffing, web servers can return X-Content-Type-Options: nosniff which opts out browsers from sniffing the content.

This is the final episode of 2018. We will discuss the difference between Availability vs Scalability in software services. Availability What does it mean for my software to be available?  software, service, application is designed in way so it can be available to consumers despite situation  Will your service be available if Host Failure Maintenance  Upgrading Security updates Available doesn’t necessarily mean performant. Scalability What does it mean for my software to be scalable?  The ability for the software to handle the increase of workload or data growth Assume photo sharing app, retrieving 1 photo with details. If in normal conditions you service can serve 100 requests per minute, will doubling resources double the output?u If the volume of data increases will your query still perform? A software is scalable when it is designed in a way so that adding more resources will handle more users   --- Support this podcast: https://anchor.fm/hnasr/supp
