Computerphile on Cyber Security

Computerphile on Cyber Security

Computerphile is a Youtube sister channel of Numberphile. Where Numberphile’s videos are about the magic behind match and numbers, Computerphile’s videos are all about computers and computer stuff. I recommend both channels in general, and have watched many of their videos already.

Yet, over the past weeks I specifically enjoyed what seems to be several series of videos on Cyber Security related topics.

What makes a good password?

One series is all about passwords.

What are strong passwords, which are bad? How can hackers crack yours? And how do websites secure user passwords?

The videos below are in somewhat of the right order and they make for an interesting insight in the world of password management. They give you advice on how to pick you password, and even a nice tool to check whether your password has ever been leaked.

Probably, you will want to change your password afterwards!

Hacking and attacking

If you are up to no good, please do not watch this second series, which revolves all around hacks and computer attacks.

How do people get access to a websites database? How can we prevent it? How can we recognize security dangers?

You might know of SQL injections, but do you know what a slow loris attack is? Or how ransomware works? Or what exploitX is?

These videos nicely continue the line of a previous post on Try Hack Me’s Cyber Security Challenges, where you can learn how computers work and where there vulnerabilities lie.

Practical Tools for Human-Centered Design

Practical Tools for Human-Centered Design

Google’s guidebook to human-centered AI design refered to the Design Kit, containing numerous helpful tools to help you design products with user experience in mind.

The design kit website contains many practical methods, tools, case studies and much more resources to help you in the design process.

Human-centered design is a practical, repeatable approach to arriving at innovative solutions. Think of these Methods as a step-by-step guide to unleashing your creativity, putting the people you serve at the center of your design process to come up with new answers to difficult problems.

The design kit methods section provides some seriously handy guidelines to help you design your products with the customer in mind. A step-by-step process guideline is offered, as well as neat worksheets to records the information you collect in the process, and a video explanation of the method.

Google’s Responsible AI Practices

Google’s Responsible AI Practices

As a company that uses a lot of automation, optimization, and machine learning in their day-to-day business, Google is set on developing AI in a socially responsible way.

Fortunately for us, Google decided to share their principles and best practices for us to read.

Google’s Objectives for AI applications

The details behind the seven objectives below you can find here.

  1. Be socially beneficial.
  2. Avoid creating or reinforcing unfair bias.
  3. Be built and tested for safety.
  4. Be accountable to people.
  5. Incorporate privacy design principles.
  6. Uphold high standards of scientific excellence.
  7. Be made available for uses that accord with these principles.

Moreover, there are several AI technologies that Google will not build:

For the details behind these six best practices, read more here.

  1. Use a Human-centered approach (see also here)
  2. Identify multiple metrics to assess training and monitoring
  3. When possible, directly examine your raw data
  4. Understand the limitations of your dataset and model
  5. Test, Test, Test,
  6. Continue to monitor and update the system after deployment
10 Tips for Effective Dashboard Design by Deloitte

10 Tips for Effective Dashboard Design by Deloitte

My colleague prof. Jack van Wijk pointed me towards these great guidelines by Deloitte on how to design an effective dashboard.

Some of these rules are more generally applicable to data visualization. Yet, the Deloitte 10 commandments form a good checklist when designing a dashboard.

Here’s my interpretation of the 10 rules:

  1. Know your message or goal
  2. Choose the chart that conveys your message best
  3. Use a grid to bring order to your dashboard
  4. Use color only to highlight and draw attention
  5. Remove unneccessary elements
  6. Avoid information overload
  7. Design for ease of use
  8. Text is as important as charts
  9. Design for multiple devices (desktop, tablet, mobile, …)
  10. Recycle good designs (by others)

In terms of recycling the good work by others operating in the data visualization field, check out:

I just love how Deloitte uses example visualizations to help convey what makes a good (dashboard) chart:

Google’s Guidebook for Developing AI Product Development

Google’s Guidebook for Developing AI Product Development

I came across another great set of curated resources by one of the teams at Google:

The People + AI Guidebook.

The People + AI Guidebook was written to help user experience (UX) professionals and product managers follow a human-centered approach to AI.

The Guidebook’s recommendations are based on data and insights from over a hundred individuals across Google product teams, industry experts, and academic research.

These six chapters follow the product development flow, and each one has a related worksheet to help turn guidance into action.

The People & AI guidebook is one of the products of the major PAIR project team (People & AI Research).

Here are the direct links to the six guidebook chapters:

Links to the related worksheets you can find here.

10 Guidelines to Better Table Design

10 Guidelines to Better Table Design

Jon Schwabisch recently proposed ten guidelines for better table design.

Next to the academic paper, Jon shared his recommendations in a Twitter thread.

Let me summarize them for you:

  • Right-align your numbers
  • Left-align your texts
  • Use decimals appropriately (one or two is often enough)
  • Display units (e.g., $, %) sparsely (e.g., only on first row)
  • Highlight outliers
  • Highlight column headers
  • Use subtle highlights and dividers
  • Use white space between rows and columns
  • Use white space (or dividers) to highlight groups
  • Use visualizations for large tables
