In this video I clean my 1% and 2% tolerance resistors (my 5% tolerance resistors were cleaned previously). That’s 37 component trays worth, being 37 different types from 1Ω to 1MΩ. During the video I print new labels for the component drawers with my label maker and I use my iPhone to double check the colour coding.

In this video I unbox and install my new Horusdy 39-drawer component drawers.

Unfortunately I missed a little bit of footage near the end of the installation because my camera locked up.

Fixing duplication in HTML title element for WordPress with Yoast SEO installed

Posted on by

I was having a problem in WordPress for my blog where the title contained duplicate values, like “John’s blogJohn’s blog”.

The fix for me was to edit wp-content/themes/twentyeleven/header.php and disable a bit of the output, as shown below. I basically just added an if ( false ) to disable the code which caused the duplicate content.

This seems to effectively mean that Yoast SEO is in charge of the titles now. You can configure separately the homepage, posts, and pages titles in the Yoast SEO settings. I configure mine in Yoast SEO Settings / Content Types like this:

Homepage
Site title Separator Tagline
Posts
Title Separator Site title
Pages
Title Separator Site title
<title>
<?php
  // Print the <title> tag based on what is being viewed.
  global $page, $paged;

  wp_title( '|', true, 'right' );

// 2024-07-14 jj5 - OLD: I removed this because wp_title() (above) does everything that needs to be done.
if ( false ) {
  // Add the site name.
  bloginfo( 'name' );

  // Add the site description for the home/front page.
  $site_description = get_bloginfo( 'description', 'display' );
  if ( $site_description && ( is_home() || is_front_page() ) ) {
    echo " | $site_description";
  }

  // Add a page number if necessary:
  if ( ( $paged >= 2 || $page >= 2 ) && ! is_404() ) {
    /* translators: %s: Page number. */
    echo esc_html( ' | ' . sprintf( __( 'Page %s', 'twentyeleven' ), max( $paged, $page ) ) );
  }
}
?>
</title>

In this video I unbox an Ampcom Automatic Network Cable Tester from AliExpress. It was a bit confusing because the AliExpress page says this is an ANENG M469D. But actually it’s not. It’s an Ampcom Automatic Network Cable Tester, which is a similar bit of kit. In the video I test this equipment with both a normal patch cable and a crossover cable and it seems to work okay, so for five bucks I’m a happy customer.

Silly Job Title: Amp Alchemist

Note: this video is nearly five hours long! If you’re interested but don’t have 5 spare hours (and who does??) you might like to listen at 2x speed or more. The standard YouTube interface only supports playback up to 2x speed but I have some notes about YouTube hacks you can use to set the playback at 3x speed… or more!

In this video I teardown “Radio Engineering” (3rd edition) by Frederick Terman published 1947.

Frederick Terman was a Doctor of Science which is what the Sc.D. after his name stands for. It’s like a Ph.D. He is remembered as a father of Silicon Valley.

In the book there is much talk of diodes, but of course that is in reference to the old thermionic diodes which were vacuum tubes. These days diodes are semiconductors made from something like silicon or germanium.

The book talks a lot about power amplifier classes. Today the same classes are still used, it’s just that anything other than class AB and class D are very uncommon.
