Welcome to the tech meme ride home for Friday, April 17th, 2020. I'm Brian McCullough today.

Microsoft has some AI tech that can catch bugs 99% of the time it says.

Why Combinator is going to be more picky about who it invests in.

Mac OS is getting a smarter battery management system for your laptop and of course the weekend long read suggestions.

Here's what you missed today in the world of tech. Microsoft claims it can now use AI to distinguish between security and non-security

bugs 99% of the time and it can identify high priority security bugs 97% of the time. It plans to open

up the methodology behind all of this to make it possible for you to maybe do the same in coming months quoting venture beat the work

suggests that such a system which was trained on a data set of 13 million work items

and bugs from 47,000 developers at Microsoft stored across

Azure Devops and GitHub repositories could be used to support human experts.

Corologics estimates that developers create 70 bugs per thousand lines of code

and that fixing a bug takes 30 times longer than writing a line of code.

In the US, $113 billion is spent annually on identifying and fixing product defects.

Microsoft model leverages two techniques to make its bug predictions.

The first is a term frequency inverse document frequency algorithm, a T.F. I.

An information retrieval approach that assigns importance to a word based on the number of times it appears in a document

and checks how relevant the word is throughout

a collection of titles.

Microsoft says that its bug titles are generally very short containing around 10 words.

The second technique, a logistic regression model, uses a

logistic function to model the probability of a certain class or event existing.

Microsoft says that the model is deployed in production internally and that it is continually
