Nice thread starting on the current state of CAs promoting OV/EV instead of doing innovation, with many comments on how to properly use LetsEncrypt

On CAs: [Archive.is] Thread by @sleevi_: “It’s a real shame that CAs have gotten so high off their own supply, that they’ve become blind to the real problems they cause by promoting OV/EV. It’s almost as if they believe that 1988 had all the solutions, and we’ve been declining since then. Example: Let’s say we accept that organizational identity is a valuable component. Coupling it to TLS is terrible, because it encourages all the bad practices we see – such as making it hard to obtain or automate certificates, discouraging key rotation, extending cert lifetime […]”

MS Excel 2011 for Mac: How to Change Data Source for a Pivot Table

Posted by jpluimers on 2018/08/24

Based on [WayBackMS Excel 2011 for Mac: How to Change Data Source for a Pivot Table:

  • Refreshing the data is in the “PivotTable” toolbar under “Data”: either
    • “Refresh” for the current PivotTable or
    • “Refresh All” for all PivotTables in the spreadsheet
  • Setting the range of source data is “Change Source” in the “PivotTable” toolbar under “Data”
    • If your data is on a sheet by itself, it’s better to select the range using column only notation than using column:row notation, compare these:
      • ‘FRITZ!Box_CallList.csv’!$A:$S
      • ‘FRITZ!Box_CallList.csv’!$A$1:$S$401

The last trick makes it way easier to add newer data from an external CSV file into an existing workbook with various PivotTable analysis worksheets:

  1. Append the CSV data to the source
  2. Copy over any formulas needed to make pivot life easier
  3. “Refresh All”

On a 1920×1200 screen, the PivotTable toolbar looks like this:
