Premier league table – some trends this season

That chart from the BBC got me interested. Looking at the Premier league table distributed by points makes it lot more interesting than distribution by ranks.

So, I downloaded the Premier League data for current season from Football Data, and created some graphs1.

Weeks 1-8: Mixed bag, except for Crystal Palace

Crystal Palace's dismal start to the season

7 straight defeats! Crystal palace really had a crap start to the season!

Chart of the day: Premier league table

Premier league teams on a linear scale of points after 23 matches

The usual Premier league table gives a good idea of the ranking, but the gaps between teams aren’t immediately obvious1. I love how this visualisation shows both the rankings and the gaps with one simple line.

Guy Kawasaki’s 10/20/30 presentation deck rule

A PowerPoint presentation should have ten slides, last no more than twenty minutes, and contain no font smaller than thirty points.


The “or else” implication, in Mark Twain’s words:

I didn’t have time to write a short letter, so I wrote a long one instead.

TIL: Conditional sum product in Google Sheets

=SUMPRODUCT(D5:D1009="",C5:C1009,B5:B1009)

Just learnt an easy way to do conditional SumProduct1 calculations in Google Sheets2.

In above example, I wanted the SumProduct of values in columns B and C, when the respective cell in column D was empty.

The solution is to simply introduce the conditional column as another input, with the condition stated in the input.

Sheets does the SumProduct calculations, with each true as 1, and false as 0, thus making it a Conditional SumProduct :)

Biometrics – to identify, not authorise

Biometrics are your username, not your password.

This tweet by Koushik made a lot of sense on first reading. But I couldn’t place my finger on why I agreed with it. Until I read the paragraph below:

All ‘passwords’ should be replaceable. If your credit card gets stolen, you can block it and get a new card. If your Aadhaar number and fingerprint are leaked, you can’t change it, you can’t block it.

That clinches it for me.

If my password gets stolen, I can reset it to something new, something stronger.

What do I do if my fingerprint is my password? Can’t get a new fingerprint.

Can’t get a new retina, or DNA either. And they’re all a fair bit easier to steal than a strong password.

Sure, use biometrics to identify if you want. But follow the identification with authentication (with a password, or more), before giving that identity any authority.

Some feedback: WordPress reader on desktop

Navigation in reader

  • There are no visible cues hinting at ability to navigate from one expanded post to the next (or previous).
  • Navigating back to the post list (using back button), and then to next post makes it slow, and click heavy.
  • Keyboard shortcuts work, but there are again no visible cues indicating even their presence.

Keyboard shortcuts

  • No visible hints that any keyboard shortcuts exist
    • Keyboard shortcut discoverability is solely by trial and error, or ‘Google’
    • Traditionally, pressing ‘?’ (in, say, GMail or Pocket) brings up relevant shortcuts modal. Doesn’t work in reader.
    • One suggested hint could be to place a keyboard icon next to the help (?) icon, at the bottom, in the left navigation bar.
  • Navigation shortcuts
    • j/k navigate to next/previous post as expected. However, the more ‘lay’ user-friendly left-arrow/right-arrow versions don’t.
    • esc key works the same as browser’s back button – navigating back through history stack (i.e. going back to last viewed post).
      • A better (expected) implementation would be to jump out of expanded-post view to the posts list view, ideally scrolled to the last viewed post.
  • Like keyboard shortcut, l, works as expected. Adding f as an additional activator would be useful – a lot of platforms use favourite as an alternative to like, and some users may be more behaviourally trained to press f instead of l
