Why are there so many Machine Learning paid certifications?



I often wonder when I see people completing certificates on ML, are these more for showing the world that you know and understand ML or is it really a sense of achieving something! If it is the latter then why pay ? and why need a certificate at all?

Let me elaborate on the resources that are free and can do a better job than most paid ML courses:
  • GitHub Awesome Machine Learning - https://github.com/josephmisiti/awesome-machine-learning
    • For a list of free machine learning books available for download, go here.
    • For a list of (mostly) free machine learning courses available online, go here.
    • For a list of blogs on data science and machine learning, go here.
    • For a list of free-to-attend meetups and local events, go here.
  • Finally the mindmap! - https://github.com/dformoso/machine-learning-mindmap

And there are all the competitions on Kaggle that can boost your practical knowledge that no certificate can! I am sure there are many more , would love to hear from others what are the other resources that you have seen.

Software Testing @ Microsoft

Image
In continuation from my previous  series of posts  targeting testing in top few companies from the technology space. After  Software Testing @Facebook  and @Google  we shall now look at Microsoft: Testing@Microsoft Software Development Engineers in Test (SDETs) are usually just called Test and sometimes Software Testing. SDETs are responsible for maintaining high testing and qualityassurance standards for all Microsoft products. Software Development Engineers (SDEs) are often referred to as Software Development. SDEs write the code that drives Microsoft products and upgrades. Very few teams in Microsoft are still using SDETs to do significant amount of manual testing. Manual testing is mainly outsourced. Actually, as early as in 2004, for example, most of the manual testing of MSN Explorer was outsourced. Think about it this way: it just doesn't make sense for test manager to spend their headcount (SDETs) on something can be easily outsourced.  Until 2005, Microso

Trim / Remove spaces in Xpath?

Image
If you are wondering how you can trim the spaces in your xpath, this is how: The normalize-space function strips leading and trailing white-space from a string, replaces sequences of white-space characters by a single space, and returns the resulting string. Example : Which one is better? //td[starts-with(normalize-space(),'Text to Trim')] //td[starts-with(normalize-space(text()),' Text to Trim ')] The second option is better as it targets at the specific nodes More string functions in XPATH: Functions Description starts-with( string1 ,  string2 ) Returns true if the first string starts with the second string. contains( string1 ,  string2 ) Returns true if the first string contains the second string. substring( string offset length ) Returns a section of the string. The section starts at  offset (which is a number), and is as long as the value provided at  length. substring-before( string1 ,  string2 ) Returns the part of  string1  up unti
