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

Sde intercept Any operation performed on ArcGIS ends up eventually to the geodatabase as a set of one or more queries. A “zoom-in” or pan operation translates to multiple queries to the underlying geodatabase. SDE intercepts always you to intercept and take a look at those queries to diagnose slow operations in your enterprise geodatabase. It also helps pinpoint where the bottle neck is and how can you optimize your app or geodatabase. https://support.esri.com/en/technical-article/000010355 --- Send in a voice message: https://anchor.fm/hnasr/message
