Bookmarklets for Archive.is and the WayBack Machine to go to the original page

Posted by jpluimers on 2023/06/07

Quite often, when browsing an archived page on Archive.is or the WayBack Machine, I want to check the current status of the original page.

So I wrote a few Bookmarklets.

Archive.is

Default field

Any Archive.is page has a Saved from field which is an input html element having a name attribute with value q and a value property containing the URL, which is navigated to by assigning the location in the above code.

So my goto Bookmarklet is this one:

javascript:open(document.getElementsByName("q")[0]?.value)

It uses [0]? as there is no getElementsByName, but there is [Wayback/Archive] Document.getElementsByName() – Web APIs | MDN as name values need not to be unique but id values have to be.

Other Archive.is fields

The above works on all types of Archive.is page types:

  1. search pages like https://archive.is/https://example.org
  2. actual archived pages like https://archive.is/LkpeZ and https://archive.ph/2022.01.22-165646/https://example.org/
    • these only have a Saved from field.
  3. redirected archived pages like https://archive.ph/UEQeg and https://archive.ph/2013.01.03-111457/http://www.iana.org/domains/example/
    • these both have Saved from and Redirected from fields.
  4. complex pages like https://archive.ph/5iVVH and https://archive.ph/2015.11.14-044109/http://www.example.org/
    • those have even more fields: in addition to fields Saved from and Redirected from, the fields Via and Original also are added.

To get the additional fields from the other fields, we need to figure out a way to access them.

What is the difference between <p>, <div> and <span> in HTML&XHTML?

Posted by jpluimers on 2023/06/06

I write most of my documentation in Markdown or reStructuredText, so I don’t bump into html questions as often as in the past. But recently, I had to document in html as markdown was impossible, bumped in the choice between using div or p tags for paragraphs, and remembered there was a p problem not present with div but forgot which problem.

So I found [Wayback/Archive] What is the difference between <p>, <div> and <span> in HTML&XHTML? where the red bit explained what I forgot:

As others have answered… div and p are “block elements” (now redefined as Flow Content) and span is an “inline element” (Phrasing Content). Yes, you may change the default presentation of these elements, but there is a difference between “flow” versus “block”, and “phrasing” versus “inline”.

An element classified as flow content can only be used where flow content is expected, and an element classified as phrasing content can be used where phrasing content is expected. Since all phrasing content is flow content, a phrasing element can also be used anywhere flow content is expected. [Wayback/Archive] The specs provide more detailed info.

All phrasing elements, such as strong and em, can only contain other phrasing elements: you can’t put a table inside a cite for instance. Most flow content such as div and li can contain all types of flow content (as well as phrasing content), but there are a few exceptions: p, pre, and th are examples of non-phrasing flow content (“block elements”) that can only contain phrasing content (“inline elements”). And of course there are the normal element restrictions such as dl and table only being allowed to contain certain elements.

While both div and p are non-phrasing flow content, the div can contain other flow content children (including more divs and ps). On the other hand, p may only contain phrasing content children. That means you can’t put a div inside a p, even though both are non-phrasing flow elements.

Now here’s the kicker. These semantic specifications are unrelated to how the element is displayed. Thus, if you have a div inside a span, you will get a validation error even if you have span {display: block;} and div {display: inline;} in your CSS.

Thanks [Wayback/Archive] Dhamu for asking that question and [Wayback/Archive] chharvey for explaining these details!

The [Wayback/Archive] HTML Standard: 3.2.5.2 Kinds of content has a cool diagram too:

GitLab pages on a custom domain are nice, but be aware of intermittent 502 and certificate errors

Posted by jpluimers on 2023/06/05

Reminder to self GitLab pages on the gitlab.com are free, so Setting up a GitLab project so it is served over https as a gitlab.io and a custom subdomain comes with two caveats:

  1. Intermittent HTTP error 502 Bad Gateway
  2. Intermittent NET::ERR_CERT_COMMON_NAME_INVALID (Chrome) or SSL_ERROR_BAD_CERT_DOMAIN (Firefox):

Different ways for installing Windows features on the command line – Peter Hahndorf

Posted by jpluimers on 2023/06/02

If course you can configure Windows Optional Features using the GUI as for instance explained at [Wayback/Archive] How to manage Windows 10’s many ‘optional features | Windows Central.

However, I prefer command-line management.

About the only post doing the comparison of command-line mangement options I could find about is [Wayback/Archive] Different ways for installing Windows features on the command line – Peter Hahndorf and hopefully will be further updated in the future. It is dated 2015, but has been updated until at least Windows Server Nano.

I added one, and then rewrote the tool-set availability table in the post into this:

For my link archive: Microsoft account activity policy – Microsoft Support

Posted by jpluimers on 2023/06/01

Bumped into [Wayback/Archive] Microsoft account activity policy – Microsoft Support because an account that I hardly use was about to expire.

A few quotes (but be sure to read the most up to date policy):

  • Except as provided below, you must sign in to your Microsoft account at least once in a two-year period to keep your account active. If you don’t sign in during this time, Microsoft will consider your account to be inactive.
  • Exceptions: The activities below are exceptions that will result in Microsoft extending your account’s active status, even if you have not otherwise signed in to your Microsoft account within a two-year period.
    • Purchases
    • Subscriptions
    • Publishing to the Microsoft Store
    • Certifications
    • Account Balance
    • Accounts Payable
    • Family Accounts
    • Legal Requirements or as otherwise provided by Microsoft

Probably the easiest way at the time of writing is to make sure there is an account balance.

Why I try to keep an online copy of my bookmarklets in html instead of Markdown

Posted by jpluimers on 2023/06/01

As Chrome mangles Bookmarklets to a partially escaped form (I think using Percent encoding), I first tried to document my Bookmarklets in Markdown so I could easier edit them and copy these JavaScript links  to various browsers. That failed, because the html rendered from the Markdown didn’t contain the links any more. So I now use plain html for documenting them which is a pain to edit but works.

[Wayback/Archive] Some bookmarklets hosted as [Wayback/Archive] Some bookmarklets – cached 1 minute – throttled and [Wayback/Archive] Some bookmarklets – cached 1 year – CDN.

This is why:

  1. Technically you can include JavaScript for Bookmarklets in Markdown documents both as Markdown links (either with escapes or by splitting reference and link in two pieces) and html links (as embedding html in Markdown is allowed): [Wayback/Archive] Bookmarklet link in Markdown document – Stack Overflow (thanks [Wayback/Archive] Adam Haile, [Wayback/Archive] Zombo and [Wayback/Archive] stevemegson)
  2. Because of security reasons, many hosters will filter out JavaScript when transforming Markdown in html [Wayback/Archive] Embed JavaScript in GitHub README.md – Stack Overflow (thanks [Wayback/Archive] Matt Smith and [Wayback/Archive] coyotte508)

Searches: [Wayback/Archive] markdown javascript in link – Google Search and [Wayback/Archive] “embed javascript” in markdown – Google Search.
