Mark Zuckerberg is just like us.

Well, only in that he also appears to be using the secure messaging app Signal, despite owning WhatsApp, one of its largest competitors.

'Regarding the #FacebookLeak, of the 533M people in the leak — the irony is that Mark Zuckerberg is regrettably included in the leak as well,' . He redacted part of Zuckerberg's number, but says he found that Zuckerberg's leaked phone number was associated with a Signal account — the chat app that has end-to-end encryption and is a direct competitor to Facebook's WhatsApp.

The method used to obtain the private information from Facebook has been patched, a company spokesperson confirmed to . But the spokesperson did not comment about whether Zuckerberg's information was among the data that was leaked.
In response to Walker's discovery, Signal had a little fun, tweeting a link to a story about Zuckerberg's Signal account, writing, 'With the May 15th WhatsApp Terms of Service acceptance deadline fast approaching, Mark leads by example.'

WhatsApp's — which was initially planned to be implemented on Feb. 8 but was put on hold after public backlash — includes changes 'related to optional business features on WhatsApp, and provides further transparency about how we collect and use data,' . The update will not affect 'the privacy and security' of personal messages and calls, which will still be protected by end-to-end encryption, according to the post.
Users who don't accept the WhatsApp changes will not be able to read or send messages, but will be able to receive calls and notifications for 'a short time.' If you're affected by the changes, you can always delete your account, download a report of it, export your chat history, and head to another chat service with end-to-end encryption.
I mentioned Markdown in an earlier post. Markdown is a system of markup for a plain text document designed to produce valid HTML content for the web directly from that readable text document. This is a tutorial for Markdown that I wrote mainly to learn about it. By writing a Markdown tutorial in Markdown itself, I could quickly learn all the features of the markup. Using a tool fixes it more securely in your mind than just reading about it—at least it does in mine.
Table of Contents
Purpose of Markdown
Markdown is designed to produce readable source text for the web. All of the markup consists of punctuation marks, many from the days when e-mail messages were plain text without the benefit of HTML or CSS formatting to show bold, italics, etc. So users took to writing *bold* and _italics_ to show their intent. But the key is readable source text. You should be able to display or print a Markdown document and read it without having to navigate a maze of angle brackets, tags, and attributes. To see what I mean, you can view the source text of this document. You can manage your content much better when it is readable plain text documents.
Markdown in ResophNotes
Markdown is a limited set of plain text markup that translates to the HTML tags you use in writing content for the web (as opposed to use in laying out a web page). There are a lot of elements for which there is no Markdown markup, e.g., tables. This is, however, not a serious problem as Markdown will accept HTML code within the document and simply pass it through when the markup is converted to HTML. The original Markdown is a Perl script available from the author John Gruber’s Daring Fireball site. The script processes the markup to produce a snippet of HTML suitable for inserting into the code for a web page.
I use ResophNotes to write Markdown-formatted documents. ResophNotes has a nice implementation of Markdown, with a built-in mini-browser to display the marked up document. You can use the View Source option in the mini-broswer to copy the resulting HTML code for pasting into a web page.
Document Structure
The basic unit of structure in Markdown is the paragraph. No particular markup is required for a paragraph. You simply separate blocks of text with a blank line (by pressing Enter twice at the end of the paragraph) to create a paragraph. As in HTML, the most visible document structure elements are headings. With Markdown, you can markup headings in two ways. If you want to use only H1 and H2, you can underline the heading text with equal signs (H1) or hyphens (H2). Thus, a heading marked like this in the source text document:
is converted to the following HTML when processed through the Markdown script or the Markdown generator in ResophNotes:
Note that the number of underline characters is irrelevant; even one will work. The second way to markup headings is by inserting one to six #s before the heading text. Thus, this markup:
is converted to:
If it pleases your eye better, you can close the hash marks like this:
(the number of closing hashes is irrelevant as the number of opening hashes controls the heading level).
Horizontal rules are inserted in the source text using three or more *s or -s on a line by themselves. The *s or -s may be separated by spaces. For example, each of the lines of markup below is converted to <hr />:
Manual line breaks are inserted by ending a line of text with two or more spaces, which are converted to <br />.
Blockquotes are marked up as quoted messages are in e-mail, with a leading > on the line. This markup:
is rendered as:
This is the markup for a blockquote paragraph. You
see that you only have to place a single > at the beginning of the paragraph to indent the entire paragraph.
Using the single >, however, does not display well in the source text. For the source text, it is better to use a hard return at the end of each line and place a > before each one, like this:
which renders slightly different in the browser as using the single >, but is still a blockquote:
This is the markup for a blockquote paragraph. If
you use a > at the beginning of each line and
place a hard return at the end, it is much more
obvious in your source text that this is a
blockquote.
Blockquotes may be nested and have multiple paragraphs, as illustrated by this markup:
which renders as:
Lorem ipsum dolor sit amet, consectetur adipiscing
elit. Maecenas nec purus vitae leo posuere blandit a
a sem. Morbi a sapien et leo posuere placerat.
Cras ultricies, sapien tincidunt semper accumsan,
ante odio ultricies diam, ac molestie orci sapien
sed nunc.
Nulla vitae leo id purus vestibulum gravida
sit amet eu arcu. Aenean nec turpis eget nisi
bibendum condimentum at nec libero. Cras
viverra molestie vestibulum.
Morbi ante mi, lobortis quis eleifend vel, commodo
eget ipsum. Sed hendrerit orci id erat dignissim ac
dapibus massa condimentum.
Text Formatting
The only text formatting markup is for italic and bold. Standard Markdown markup calls for a string of text to be wrapped in single symbols, either _ or *, to produce italic or double symbols to produce bold. Thus, either:
is converted to:
and:
is converted to:
Lists
Markdown allows you to insert either an ordered (numbered) list or an unordered (bullet) list. Ordered lists are marked up by inserting a number followed by a period at the beginning of a line. Unordered lists are marked up by inserting a -, *, or + at the beginning of a list item. The number or symbol may be indented up to 3 spaces (at the 4th space, Markdown thinks you want to insert a preformatted line) and must be followed by at least one space or a tab. Lists may be nested and other block or span markup may be included within a list item. If a list item includes a second paragraph or other block element, it must be indented by at least 4 spaces or a tab. Preformatted blocks must be preceded by two tabs, one to signal a block element within a list item and one to signal preformatted text. For example, the following markup for an unordered list:
is converted to:
and renders as:
- First list item in unordered list
- Second list item in unordered list
- First list item in nested unordered list
Second paragraph of the first list item in the
nested list - Second list item in nested unordered list
- First list item in nested unordered list
- Third list item in unordered list
In the HTML code above for the unordered list, notice how list items with
a second paragraph or a blank line above or below the item are wrapped in
paragraph <p> tags. If you want all your line spacing equal, you will have to style the paragraphs that occur within list items.
Ordered lists are marked up by including a number followed by a period as the first characters on a line. Again, the 3-space max indent holds. The order of the numbers in source text does not matter, although the author of Markdown suggests beginning with 1., just in case Markdown ever allows numbering beginning with other than 1. For example, this markup:
is converted to:
and renders as:
- First item of ordered list
- Second item of ordered list
- First item of nested ordered list
- Second item of nested ordered list
- Third item of ordered list
Links
There are several ways to markup links in Markdown. The basic inline markup is:
The URL can be an internal named anchor or an element ID preceded by a hash mark (#).
Links can also use a reference style markup to keep from cluttering up the source text with lengthy and complicated URLs:
or
The URL is specified anywhere in the document after the link markup and may be relative or absolute. For the markup using a reference text (e.g., reference_id above), the URL is associated with the reference_id like this:
For markup using an “empty” reference text set of brackets, the “Link text” serves as the reference text for the URL:
I like to list the link references at the end of the document, like endnotes. I think it keeps the source text cleaner, i.e., more readable. You can see the link references for this document by scrolling to the end of the source text.
Images
Images are inserted into the Markdown markup in a manner similar to links, but using an exclamation point at the beginning of the line. It works well for a simple, inline image.
Images can also use the same style as reference links:
with the URL linked to the reference_id thusly:
If you need to have more control over image positioning or size, it is best just to use the HTML <img> tag and styling.
Preformatted Blocks and Spans

Markdown makes it easy to write about HTML and other code. To wrap a block text in <pre><code> tags, simply indent each line by at least 4 spaces or 1 tab. Thus:
is converted to:
and renders as:
Normal indent paragraph
Back to normal paragraph
Code spans are inserted in source text by enclosing the text string in backticks. For example:
is converted to:
and renders as:
To include a literal backtick in an <h1>Heading</h1> string,
you must use 5 backticks, which looks like `
Literal Characters
The Markdown markup characters can be inserted literally in the rendered page by escaping with a backslash before the markup symbol. Thus to insert a literal underscore character:
renders as:
Insert a backslash before the underscore character to insert a literal underscore like this _
Other Features
Markdown includes a neat feature for clickable e-mail addresses. Enclose the address in the source text with angle brackets and some encoding will result, which serves as a low-level spam barrier. Some spam bots will probably break the code, but it is better than nothing. For example:
Signal Mark Spam
is converted to:
and renders as clickable e-mail address:
Similarly, if you enclose a web address in angle brackets:
Signal Market Cap
it converts to:
Signal Marketing Automation
and renders as a clickable web address:
