HTML cleanup tool & simplifier. For basic & clean HTML 🔧

Posted by jpluimers on 2021/10/21

I have used other on-line HTML cleanup tools in the past (especially for including parts of web-pages in a blog post), but so far none beats HTML Washer: [Wayback] HTML cleanup tool & simplifier. For basic & clean HTML 🔧

An online tool that reduces HTML to basic tags and attributes. Removes scripts, CSS, and other non-basic elements like , , etc… Also, corrects errors and formats the HTML doc or a fragment.

For WiFi guest networks with a fixed SSID: QR code – Wikipedia

Posted by jpluimers on 2021/10/06

Access Denied

Access Denied

I knew it was possible to generate QR codes to access quest networks (as the QR code has credentials) for WiFi networks having a fixed SSID.

I just never bothered, but did when needed home care with quite a few different people providing the care.

Generating was easier than I anticipated, though I hoped I just could put the parameters in a URL and fire off to get a page including the QR code.

Alas, the pages I found require you to enter the SSID name and key/password phrase.

That’s OK: I have saved the PNG files for our network and my brother’s as images so I can put them on-line, and printed them out so guests can scan and use the network at once.

Here we go:

  • 124 network Access Denied, key 2171TB24
  • 171 network Disconnected, key 1060NP71

Highly esteemed science: An analysis of attitudes towards and perceived attributes of science in letters to the editor in two Dutch newspapers – Stefan P.L. de Jong, Elena Ketting, Leonie van Drooge, 2020

Posted by jpluimers on 2021/10/06

All my IPv4 addresses seem to be blocked with messages like this (note the odd, but allowed, leading zero in the IPv4 address [WayBack]):

Error

The IP you are accessing the site with (037.153.243.242) has been blocked because it has triggered one of our security measures. Please see the reason below:
Block reason: This IP was identified as infiltrated and is being used by sci-hub as a proxy.
To restore access, please contact onlinesupport@sagepub.com citing this message in full.

A quick [WayBack] “This IP was identified as infiltrated and is being used by sci-hub as a proxy.” – Google Search shows they also block the Google Bot.

I am not not even going to bother with companies that have bad infiltration detection.

Of course I ensured the paper has been archived:

[WayBack/Archive.is] Highly esteemed science: An analysis of attitudes towards and perceived attributes of science in letters to the editor in two Dutch newspapers – Stefan P.L. de Jong, Elena Ketting, Leonie van Drooge, 2020.

Note I do not run sci-hub, though it tempts me doing so. For more info: [WayBack] Sci-Hub – Wikipedia

I checked the router and web-proxy for any suspicious activity. There is none.

I do run the ArchiveBot by the ArchiveTeam to support the WayBackMachine of the InternetArchive and the great team Mark Graham has there providing some bandwidth and CPU/memory resources helping them archive public internet content for posterity.

It that triggers SAGE, too bad for them.

Naughty naughty no alt: CSS style to clearly show which images lack an alt-text

Posted by jpluimers on 2021/10/05

The CSS from [WayBack/Archive.is] Naughty naughty no alt that shows the below red moving rendering of images that do not have an alt-text is simple:

  <style>
    body {
      margin: 5vw;
    }

    img {
      max-width: 25vw;
      margin: 1vw;
      box-sizing: border-box;
    }
    img:not([alt]) {
      border: 2px solid red;
      animation: pulse 1.2s ease infinite;
    }

    @keyframes pulse {
      0% {
        transform: scale(1) rotate(0);
      }
      25% {
        transform: scale(1.3) rotate(15deg);
        filter: blur(2px);
        opacity: 0.8;
        box-shadow: 0 0 2vw 2vw red;
      }
      50% {
        transform: scale(1) rotate(0);
        filter: none;
      }
      75% {
        transform: scale(1.3) rotate(-15deg);
        filter: blur(5px);
        opacity: 0.8;
        box-shadow: 0 0 2vw 2vw red;
      }
      100% {
        transform: scale(1) rotate(0);
      }
    }
  </style>

Less intrusive CSS fragements are

img:not([alt]) {
  filter: blur(5px);
}

and

img:not([alt]) {
  border: 5px solid red;
}
