Blogger Template Error Message: The reference to entity "display" must end with the ';' delimiter.

Error Message

The error message on Blogger looks as such:

My Case

In my case, that was from a link (stylesheet) href value provided by Google Fonts. By default, they put the &display=swap parameter in the URL — specifically, in the query string.

On a regular HTML page, that should be fine. But on Blogger, it is unacceptable. Blogger employs super regular HTML.

Ah, let's use this font. Splendid.

Please save the template, Blogger. (Hits save button.)

Oi!

Yes?

The reference to entity "display" must end with the ';' delimiter.

What does that mean?

The reference to entity "display" must end with the ';' delimiter.

(Removes the value after "display". Places ';' after "display". Hits save button.)

Oi!

Yes?

The reference to entity "display" must end with the ';' delimiter.

⬆️ The XML parser saw the & symbol and it threw a robotic tantrum because I did not escape it.

My Solution

In short, it's an XML escaping issue. The word "display" just happened to be whatever came after the & (ampersand).

So the solution for this particular case is either:

Simply omit the &display=swap ⬇️

But that's... quite... silly. 🤔
Or, escape the & with & ⬇️

⬆️ Now, that is better! 🥳

That is all, I believe. Cheers. 🍺

GPT-5

Hello. OpenAI released the latest models: GPT-5 and GPT-5 Thinking . I usually on GPT-4o for casual banters about anything. Most of the idle times, about films and telly shows I watched randomly. For instance, this was one of my observations. ⬇️ Why did people in a jungle expedition (in those shows) wear tank tops knowing they'd be, at least, in a jungle? Shouldn't safety be the first consideration? Not that we can't wear tank tops in the jungle. But when the story is about gigantic venomous, aggressive spider, reptile, other muppets — it means safety is numero uno. Of course, it's for the sex appeal. The "begone, logic" template. Oh wait, I answered my own question. But let us do continue. 🤦 I also saw other film with similar trope, all the females wore tank tops. When they were in trouble of sort, all other characters had clean clothes and faces but this one lady. She had grease on her face. And her clothes. So apparent. She ...

Blogger Template Error Message: "XML document structures must start and end within the same entity."

📢 Error Message The error message on Blogger ( HTML editor) looks like this: 😵‍💫 Why? Because I accidentally deleted the closing CDATA section in a script . It was supposed to be like so: <script> // <![CDATA[ /* JavaScript lines here */ // ]]> </script> And I — with my sleight of mouse-hand, selected one line too many — deleted the closing tag: <script> // <![CDATA[ /* JavaScript lines here */ </script> Then saved the template. 😂 XML was like, (XML.) Oi! Aye? What? (XML.) Must start and end within the same entity! 👀 Which one? (XML.) Read. 🧐 My script is fine, ya muppet! Save it. S. A. V. E. (XML.) Read. 🤦‍♂️ I did! Why is your message vague? Are you a muppetlord ? (XML.) 🤷 R. E. A... Fine. 💡 Solution I was baffled by that because my script had everything escaped, the forbidden entities. I bloody checked the JavaScript code and nothing was suspicious. And then....

It Was Nothing

Hi, there. 👋 Let's examine this phrase: it was nothing. One magnificent, centuries-old paradox that everyone uses and nobody questions. You've said it. I've said it. Your nan said it after knitting an impossibly intricate jumper for Christmas. We all say it, reflexively, automatically — like a social sneeze. Someone compliments us and out it comes , dressed smartly in the clothes of humility. But hold on just a moment. 🍺 Let's Dive Picture this: A bloke on an ordinary street pulls a dame clean out of the path of a speeding car. Adrenaline. Chaos. The sheer improbability of being exactly there at exactly that moment moving at exactly the right speed. The dame, breathless and alive, turns to him — Thank you so very much! I'd be dead if you weren't there! And he says: Oh, it was nothing. Nothing. He just casually dismissed a miracle as nothing. Which means, by his own accounting, one rung above nothing would be — what, exa...

Three Wishes

If a jinni (or genie) grants you three wishes, what would you wish? I might guess something such as generic infinite riches, maybe even world peace. You know, sudden, instant gratification. That gibbon, please. Make it ride a scooter with jet. Or perhaps exploiting the technicality (loophole). Say, for instance, please grant me another x wishes , or better, another battalion of you , "you" being the jinni. How am I supposed to clone myself? — said the jinni. Unless the jinni stated the terms and conditions, we can surely find a cheeky way to get to the backdoor. And as for me, I might ignore the jinni politely. Such as, I thank thee for the generous offer, kind sir. Might I offer thee for a sugared roundel, nigh consumed, its orb defiled? Perhaps not, perhaps I'd say, Why? ⬆️ Indeed, just one word. You see, it will instantly break the spell. Because the bugger needs to explain the bugger in question. Since the bugger has a talkative nature, the ...

Bullet Chess: Caro-Kann Defense: Exchange Variation

I played defence (black) here in a 1 minute bullet game on Lichess. My opponent resigned. Quite an intense game, that was. 🤔 Not much to tell, really. But if I brought this jittery-style to a classical game... 🤣 You can use your left and right arrows on your keyboard or use the mouse scroll to see the moves back and forth on the chessboard. But first, click the board.

Elders Drinking Song

Listen on YouTube Music As if your bones heard something familiar from before you were even born. That song is from the Amis (阿美族) people of Taiwan. 老人飲酒歌 or Elders Drinking Song is a traditional Amis chant, famously performed by Difang (郭英男) and Igay (郭秀珠) who were Amis from the Maran (馬蘭社) settlement. The vocals were lifted straight from a 1988 recording of Difang and Igay singing during a French government-backed ethnomusicology project — meant for research. With EMI as the outsourced vault. EMI (Electric and Musical Industries), a commercial British label. Because even "non-commercial" academic recordings were often pressed to vinyl/CD by big labels, just for reach or preservation. EMI probably saw it as just another folk catalogue item. The original singers never expected their voices to hit global charts — through Enigma. Enigma is a German musical project founded in 1990 by Michael Cretu. They were under Virgin Records. Aside f...

JavaScript: Browser-based Audio Analysis Using AnalyserNode

Greetings. 🎩 I will demonstrate the implementation of AnalyserNode to reveal (compute) the peaks and such from an audio source. This will only output the numbers rather than an elaborate animation. In this, we can choose whether to use a sample audio (hosted on a cloud storage) or a local audio file. Highlights of the flow: // 1. Create audio element audioElement = document.createElement("audio") // Make sure we convert the source to a proper Blob first, // not URL/path string like https://www.host... or local E:\path\to\file\... // Details in the code below the demonstration. audioElement.src = [Blob] // Then append the audio element to DOM // *** // 2. Setup AnalyserNode (use global variables to keep these) // Create audio context audioContext = new AudioContext() // Define the default FFT size fftDefault = 2048 // Create analyser analyser = new AnalyserNode( audioContext, { fftSize: fftDefault } ) // Create source node from the "audioElement" ab...

Shady and Shadowy

We were discussing the creativities in our thoughts — how it can be seen as Möbius strip . After I had done my informal detective work, then I prompted this for an amusement. You know, field agents or proper operatives, they aren't like "James Bond". No, sir. But the entertainment put them as such. It's like saying a mechanic always destroys the automobile just to check the front brake mechanism. And kisses an orangutan for leisure. First of all, it's quite specific, with the orangutan. Second, how can one analyse something which isn't in its original state? But indeed, "don't judge a book by its cover." Hm. So, what's the point of having a cover then? It should be Judge a book by its price. Don't buy if it weighs more than 1 kilo. Flip precariously in the shop. Until the shopkeeper yells at you. Now, that isn't a proverb anymore. It's a practical guide on buying a physical book. We don't use it as a metaphor. ...

Using CDATA Section to Escape Characters on Blogger.com

We can preserve our string using CDATA section: <![CDATA[ ...our string here... ]]> CDATA Section Blogger uses XHTML .
