This page is for posters to test comments prior to submitting them to WUWT. Your tests will be deleted in a while, though especially interesting tests, examples, hints, and cool stuff will remain for quite a while longer.

Some things that don’t seem to work any more, or perhaps never did, are kept in Ric Werme’s Guide to WUWT.

Formatting in comments

WordPress does not provide much documentation for the HTML formatting permitted in comments. There are only a few commands that are useful, and a few more that are pretty much useless.

A typical HTML formatting command has the general form of <name>text to be formatted</name>. A common mistake is to forget the end command. Until WordPress gets a preview function, we have to live with it.

N.B. WordPress handles some formatting very differently than web browsers do. A post of mine shows these and less useful commands in action at WUWT.

N.B. You may notice that the underline command, <u>, is missing. WordPress seems to suppress for almost all users, so I’m not including it here. Feel free to try it, don’t expect it to work.

Name Sample Result
b (bold) This is <b>bold</b> text This is bold text
Command strong also does bolding.
i (italics) This is <i>italicized</i> text This is italicized text
Command em (emphasize) also does italics.
a (anchor) See <a href=http://wermenh.com>My home page</a> See My home page
A URL by itself (with a space on either side) is often adequate in WordPress. It will make a link to that URL and display the URL, e.g. See http://wermenh.com.

Some source on the web is presenting anchor commands with other parameters beyond href, e.g. rel=nofollow. In general, use just href=url and don’t forget the text to display to the reader.

blockquote (indent text) My text
<blockquote>quoted text</blockquote>
More of my text
My text

quoted text

More of my text

Quoted text can be many paragraphs long.
WordPress italicizes quoted text (and the <i> command enters normal text).
strike This is <strike>text with strike</strike> This is text with strike
pre (“preformatted” – use for monospace display) <pre>These lines are bracketed<br>with &lt;pre> and &lt;/pre>
These lines are bracketed
with <pre> and </pre>
Preformatted text, generally done right. Use it when you have a table or something else that will look best in monospace. Each space is displayed, something that <code> (next) doesn’t do.

See https://wattsupwiththat.com/resources/#comment-65319 to see what this really does.

Youtube videos

Using the URL for a YouTube video creates a link like any other URL. However, WordPress accepts the HTML for “embedded” videos. From the YouTube page after the video finishes, click on the “embed” button and it will suggest HTML like:

<iframe width="560" height="315"
        src="http://www.youtube.com/embed/yaBNjTtCxd4"
        frameborder="0" allowfullscreen>
</iframe>

WordPress will convert this into an internal square bracket command, changing the URL and ignoring the dimension. You can use this command yourself, and use its options for dimensions. WordPress converts the above into something like:

[youtube https://www.youtube.com/watch?v=yaBNjTtCxd4&w=640&h=480]

Use this form and change the w and h options to suit your interests.

Images in comments

If WordPress thinks a URL refers to an image, it will display the image
instead of creating a link to it. The following rules may be a bit excessive,
but they should work:

  1. The URL must end with .jpg, .gif, or .png. (Maybe others.)
  2. The URL must be the only thing on the line.
  3. This means you don’t use <img>, which WordPress ignores and displays nothing.
  4. This means WordPress controls the image size.
  5. <iframe> doesn’t work either, it just displays a link to the image.

If you have an image whose URL doesn’t end with the right kind of prefix, there may be two options if the url includes attributes, i.e. if it has a question mark followed by attribute=value pairs separated by ampersands.

Often the attributes just provide information to the server about the source of the URL. In that case, you may be able to just delete everything from the question mark to the end.

For some URLs, e.g. many from FaceBook, the attributes provide lookup information to the server and it can’t be deleted. Most servers don’t bother to check for unfamiliar attributes, so try appending “&xxx=foo.jpg”. This will give you a URL with one of the extensions WordPress will accept.

WordPress will usually scale images to fit the horizontal space available for text. One place it doesn’t is in blockquoted text, there it seems to display fullsize and large images overwrite the rightside nav bar text.

Special characters in comments

Those of us who remember acceptance of ASCII-68 (a specification released in 1968) are often not clever enough to figure out all the nuances of today’s international character sets. Besides, most keyboards lack the keys for those characters, and that’s the real problem. Even if you use a non-ASCII but useful character like ° (as in 23°C) some optical character recognition software or cut and paste operation is likely to change it to 23oC or worse, 230C.

Nevertheless, there are very useful characters that are most reliably entered as HTML character entities:

Type this To get Notes
&amp; & Ampersand
&lt; < Less than sign
Left angle bracket
&bull; Bullet
&deg; ° Degree (Use with C and F, but not K (kelvins))
&#8304;
&#185;
&#178;
&#179;
&#8308;

¹
²
³
Superscripts (use 8304, 185, 178-179, 8308-8313 for superscript digits 0-9)
&#8320;
&#8321;
&#8322;
&#8323;



Subscripts (use 8320-8329 for subscript digits 0-9)
&pound; £ British pound
&ntilde; ñ For La Niña & El Niño
&micro; µ Mu, micro
&plusmn; ± Plus or minus
&times; × Times
&divide; ÷ Divide
&ne; Not equals
&nbsp; Like a space, with no special processing (i.e. word wrapping or multiple space discarding)
&gt; > Greater than sign
Right angle bracket
Generally not needed

Various operating systems and applications have mechanisms to let you directly enter character codes. For example, on Microsoft Windows, holding down ALT and typing 248 on the numeric keypad may generate the degree symbol. I may extend the table above to include these some day, but the character entity names are easier to remember, so I recommend them.

Latex markup

WordPress supports Latex. To use it, do something like:

$latex P = e\sigma AT^{4}$     (Stefan-Boltzmann's law)

$latex \mathscr{L}\{f(t)\}=F(s)$

to produce

P = e\sigma AT^{4}     (Stefan-Boltzmann’s law)

\mathscr{L}\{f(t)\}=F(s)

Linking to past comments

Each comment has a URL that links to the start of that comment. This is usually the best way to refer to comment a different post. The URL is “hidden” under the timestamp for that comment. While details vary with operating system and browser, the best way to copy it is to right click on the time stamp near the start of the comment, choose “Copy link location” from the pop-up menu, and paste it into the comment you’re writing. You should see something like https://wattsupwiththat.com/2013/07/15/central-park-in-ushcnv2-5-october-2012-magically-becomes-cooler-in-july-in-the-dust-bowl-years/#comment-1364445.

The “#<label>” at the end of the URL tells a browser where to start the page view. It reads the page from the Web, searches for the label and starts the page view there. As noted above, WordPress will create a link for you, you don’t need to add an <a> command around it.

One way to avoid the moderation queue.

Several keywords doom your comment to the moderation queue. One word, “Anthony,” is caught so that people trying to send a note to Anthony will be intercepted and Anthony should see the message pretty quickly.

If you enter Anthony as An<u>th</u>ony, it appears to not be caught,
so apparently the comparison uses the name with the HTML within it and
sees a mismatch.

  1. I just had another thought about underlines.

    I think I discovered that if I could get around the automatic spam trap by writing Anthony with an empty HTML command inside, e.g. Ant<b></b>hony .

    What happens when I try that with underline?

    Apologies in advance to the long-suffering mods, at least one of these comments may get caught by the spam trap.

    • I remember seeing this test pattern on TV late at night after the National Anthem and before the local station broadcast came on early in the morning while the biscuits, bacon and oatmeal were still cooking. The first show after a weather report was “Dialing For Dollars” and you had better know the count when your phone rang…. 1 up and 3 down… to get the cash.

  2. WordPress only displays images for URLs on their own line and ending with a image file extension. If I delete the attribute string above, i.e. ?token=I7JQbQli1swRgik%2BKnIKAmCk52Y%3D then what’s left should work:

    • Now one that would permit image display:

      Update: Right clicking to get the image’s url gave me a URL that goes through WP’s cache via (slashes replaced by spaces, periods by dashes) i2-wp-com wermenh-com images winter0708 P3020227_snowbank7-jpg

    • Now just the image without a suffix:

      Update: This image uses the same URL as the previous cached image. That means we can’t use a changing suffix to force a trip around the cache any more for HTTP images. I’ll play with HTTPS later.

      • Reply to Ric W ==> Thanks — I was fielding comments on an essay using an unfamiliar tablet, and wasn’t sure which and/or both were part of HTML5. I usually use the old ClimateAudit comment Greasemonkey tool, even though its formatting is funky these days, for the tags. Don’t suppose you could update that add-in?

      • IIRC, Greasemonkey was written for CA, which uses a different theme that does WUWT.

        I don’t have the time to figure out the JavaScript code or whatever it’s written in, and I don’t have the ability to make changes that deep in WUWT.

        Instead of Greasemonkey, I often use https://addons.mozilla.org/en-US/firefox/addon/its-all-text/ . It can open up an external editor, so it has saved my butt a few times when WP loses a post I was making.

  3. Hey, what happened to the old smiley face?? When I tried to post it, this appeared:

    I wonder if WordPress changed any others?

     ☹ ☻

    The old smiley was more subtle; less in-your-face. The new one is way too garish.

    If WP keeps that up, I’ll just have to use this lame replacement:

    :-)

    Or even worse:

    You are referring to some fable as fact and covering it under ‘comparative mythology’. As a matter of fact, I have studied mythology at some point in my life.

    There is an old saying that: “Myths are other people’s religion”

    Many people don’t get this parable, so I will explicate it for you. Hinduism is a myth to Christians and Christianity is mythology to Hindus.

    By the way, I didn’t refer to anyone as a ‘christian dumb-ass’. If you choose to introduce yourself as that then it’s not my affair.

    I called you a dumb-ass but clearly you can’t even comprehend a direct insult!

    ‘darken this forum’ – what the hell are you on about?

    It’s a quote from one of the worlds greatest pieces of literature.

    I can probably handle the ‘brainless stupidity’ part, after all, I am responding to your comment.

    We agree then, you win! ;-)

  5. Sadly, this article misses the point. The purpose of the suit is not to remedy the sort of harm that the Martin Act was drafted to combat.

    I’m going to self plagiarize from a series of comments I wrote along time ago on a relevant article posted by Reason Magazine (which, incidentally so utterly failed to cover the whole issue adequately that I now consider Ron Bailey a completely unreliable journalist).

    Teh(sic) big difference is that the AG’s and their supporters violated the Anti-Ku Klux Clan act. Essentially, they sought to deprive people of their civil rights my abusing their positions.

    1) Exxon is accused of not disclosing the true risks climate change posed to their business model to shareholders. There is no evidence of this. The evidence claiming to show this was so blatantly manufactured that I was reminded of the Protocols of the Elders of Zion when I reviewed it.

    2) Exxon’s disclosures and internal communications on the subject of climate change are both internally and externally congruent. More tellingly, their educated guesses as to the equilibrium climate change sensitivity to doubling of CO2 are actually not to far off from what observations are converging on.

    3) The AG’s were working off a playbook created by the self-proclaimed Climate Accountability Institute. They knew they had no evidence of fraud. They hoped a fishing expedition would find it:

    And finally, the group sought to identify the most promising and mutually reinforcing intellectual, legal, and/or public strategies for moving forward. We are pleased to share the outcome of these preliminary workshop discussions. Among the many points captured in this report, we want to highlight the following:

    • A key breakthrough in the public and legal case for tobacco control came when internal documents came to light showing the tobacco industry had knowingly misled the public. Similar documents may well exist in the vaults of the fossil fuel industry and their trade associations and front groups, and there are many possible approaches to unearthing them.

    While we currently lack a compelling public narrative about climate change in the United States, we may be close to coalescing around one. Furthermore, climate change may loom larger today in the public mind than tobacco did when public health advocates began winning policy victories.

    See Shub Niggurath’s thorough expose.

    4) The guys assisting the AG’s were hoping to make money off a legal settlement extorted from Exxon.

    Maibach has told allies that he hopes a RICO case against oil companies will prove a financial boon to groups like his Center for Climate Change Communication.

    “If there was a settlement between the government and the fossil fuel industry” stemming from a RICO investigation, “there is no question in my mind that a good portion of that money should be spent on a national campaign to educate people on the risks of climate change, and build their resolve to work towards solutions,” Maibach told the website Grist last year.

    Maibach already receives significant grant money for just those sorts of campaigns. One recent grant from the Robert Wood Johnson Foundation funded his research on methods for “persuading the public and policy-makers to take action” on climate change.

    Congress has a proper role in uncovering civil rights violations committed by the executive branch or by states. And what Al Gore and his cultists who have embedded themselves in the Democratic Party and the civil services of the states and the federal government are trying to do to Exxon is to extort money by threatening them with a criminal investigation that has no penitentiary basis. It is no different than if a democrat like Boss Hog were to tell a newspaper to stop carrying editorials opposing Jim Crow and make a donation to the policemen’s benevolence association fund or face a code inspection that would close down their offices and condemn the building where their printing presses are sited.

    One thing I forgot. The AG’s conspiracy blatantly violates a bunch of state laws, and because of the interstate nature of the conspiracy, falls very firmly in the ambit of the federal government

  6. Sometimes Mr Stokes will take the time to write reams of nick picking that is actually argument less but it looks clever. I’m still have no idea of the relevance of his dispute about the graphs above. What follow is a an example of a Nick Stokes argument in three graphs, two of which he posted:

  12. Firstly, thank you Kip Hansen for a great post and for taking the time to respond to so many comments in this long thread.

    I totally agree with Kip and appreciate his very well written and simple explication of his aspect of metrology.

    I’ve come to this post late and have read all the comments above but only wanted to interject, if I wasn’t repeating what had been said already.

    Kip describes an obvious truth to me, that is a well know, well documented and well understood issue for practitioners in the real world.

    I’m a visual person and the commonly used image of a target to symbolise the – accuracy/precision – issue, is the first thing I thought of. But when doing this mental exercise, one can easily see that there is a need for a third term! I drew pictures of each “target” with the aim of making a cartoon example that would make it very clear to a layman.

    I was sure that anybody who had given this more than a moments thought wouldn’t have come up with the same result, so I did just a little research:

    According to ISO 5725-1and VIM**, Accuracy consists of Trueness (proximity of measurement results to the true value) and Precision (repeatability or reproducibility of the measurement) – Wikipedia

    Hope this helps to visualise the issues.

    cheers,

    Scott

      According to ISO 5725-1 and VIM*, the general term ”accuracy”, is used to describe the closeness of a measurement to the true value. When the term is applied to sets of measurements of the same measurand, it involves a component of random error and a component of systematic error. In this case trueness is the closeness of the mean of a set of measurement results to the actual (true) value and precision is the closeness of agreement among a set of results.

  13. Kip==> Thank you again for taking the time to respond. You say:

    The “measurand” is “A quantity intended to be measured. An object being measured.”
    The only time “accuracy” applies to a the mean of a set of measurements is when they are of the same measured.

    Sure, I do agree with you but wanted to tease out the very first principles.

    If you aim at one target and take one shot – one measurement of one measurand – you can only talk about
    the result in terms of trueness (the proximity of the measurement result to the true value) or how close the bullet
    hole is to the centre of the target. You can not yet talk about accuracy because that requires a knowledge of precision.
    Precision is the repeatability of the measurement, it equates to a cluster of shots – or “the closeness of agreement among a set of results”.

    I simply meant, that more than one shot is required either of the same target or single shots on multiple targets before you can determine precision.
    Once you have a “measure” of precision and trueness you can begin to talk about accuracy.

    The reason precision is a necessary condition for accuracy is because it is impossible to separate random error – or a random truth in this case – from systematic error.
    A gun bolted to a test bench hitting the bullseye in one shot can not speak to accuracy because precision hasn’t been tested. The next several shots hitting all over the target or all shots going through the hole in the bullseye will illuminate the situation however!

    If there are two sides to the argument in the thread above, I think it is because people are talking at cross purposes. One side is arguing precision and the other trueness and they are confusing either term with accuracy.

    To restate, the trueness of your tide gauge example, equates to the target’s bullseye – the instantaneous water level outside the stilling well. While the the 181 (1 millimetre resolution) “cluster”, provides precision the +/-2cm calibrated range of the apparatus added to recorded value represents its realaccuracy and true range.

    And I agree, averaging large numbers of these values will only produce a spurious accuracy because, although a quasi-precision might be gained, trueness is lowered and thus accuracy lost!

    cheers,

    Scott

  15. Nick Stokes ==> Said: October 16, 2017 at 10:11 pm

    But there is one big difference between accuracy and precision, which is in the BIPM vocabulary of metrology, much cited here, but apparently not read. It says, Sec 2.13 (their bold): “NOTE 1 The concept ‘measurement accuracy’ is not a quantity and is not given a numerical quantity value. “

    And the rest of the note? The very next sentence….. is!

    A measurement is said to be more accurate when it offers a smaller measurement error*.

    This is exactly what Kip Hansen has argued all along and exactly what Bartleby just wrote** and yet you have just gone out of your way to cherry pick the quote and completely butcher the context of the very definition you are referring to!

    *And measurement error is defined at 2.16 (3.10) thusly: “measured quantity value minus a reference quantity value”
    **Bartleby wrote: “100 measures using a device accurate +/- 2cm will result in a more precise estimate that’s accurate to +/- 2c

  16. Nick Stokes==> October 18, 2017 at 12:58 am:

    The section I quoted was complete in itself, and set in bold the relevant fact: “is not given a numerical quantity value“. Nothing that follows changes that very explicit statement. And it’s relevant to what Bartleby wrote: “a more precise estimate that’s accurate to +/- 2cm”. BIPM says that you can’t use a figure for accuracy in that way.

    Talk about perversity – I can’t imagine it would be anything else – if you really are being intellectually honest!

    Here is the whole reference (Their bold):

    2.13 (3.5)
    measurement accuracy
    accuracy of measurement
    accuracy

    closeness of agreement between a measured quantity value and a true quantity value of a measurand

    NOTE 1 The concept ‘measurement accuracy’ is not a quantity and is not given a numerical quantity value. A measurement is said to be more accurate when it offers a smaller measurement error.

    NOTE 2 The term “measurement accuracy” should not be used for measurement trueness and the term “measurement precision” should not be used for ‘measurement accuracy’, which, however, is related to both these concepts.

    NOTE 3 ‘Measurement accuracy’ is sometimes understood as closeness of agreement between measured quantity values that are being attributed to the measured.

    How could you completely miss the definition of Accuracy?

    It is defined as the “closeness of agreement between a measured quantity value and a true quantity value of a measurand.”

    It is very clear that the term is not numeric but ordinal and of course, ordinal quantities have mathematical meaning as you would well know!
