Check Out

I have had annoying formatting problems when copying from Gemini and pasting to Blogger. I asked Gemini about how to best address with problem and here is what is came up with, in a nutshell:

"Convert the above response into HTML for a blog post. Use <p> tags for paragraphs and <h3> tags for headings."

Earlier I'd tried to create a post about the use of the phrase "check out" that I'd gotten Gemini to investigate but I abandoned the attempt due to formatting frustrations. Here is the response using Gemini's HTML advice:

The Many Meanings of "Check Out"

The phrasal verb "check out" is incredibly versatile in English. Depending on the context, it can mean anything from leaving a hotel to verifying facts. Here are the most common ways it is used:

1. To Investigate or Look At

This is perhaps the most casual and common use. It means to look at something interesting or to investigate a situation.

• Example: "Hey, check out that cool car over there!"
• Example: "I need to check out that new noise my engine is making."

2. To Leave a Hotel

This refers to the formal process of paying your bill and returning your keys before leaving an accommodation.

• Example: "We need to check out of the hotel by 11:00 AM."

3. To Pay for Items (Retail)

Used when you are finishing a purchase at a store or online.

• Example: "I found everything I needed, so I'm going to go check out now."

4. To Borrow (Library)

Specifically used when borrowing books or media from a library.

• Example: "You can only check out three books at a time."

5. To Verify or Prove True

Used when confirming if information or an alibi is correct.

• Example: " The police investigated his story, and his alibi checks out." (Meaning: It is true/valid).

6. To Become Mentally Absent

A more slang usage meaning someone has stopped paying attention or has lost interest.

• Example: "The lecture was so boring that I just checked out after ten minutes."
  
  

Infographic generated by Gemini based on blog post content

I reminded Gemini about the use of the term "check out" in darts and here was the response. It added information about the darts but reprocessed the whole response. It differs somewhat from the original so I've retained both.

The phrase “to check out” is one of the most versatile phrasal verbs in the English language. It functions as both a transitive verb (doing something to an object) and an intransitive verb (just doing the action itself).

Here is a breakdown of the different contexts in which this phrase is used, ranging from formal procedures to sports terminology.

1. Investigation and Inspection

This is perhaps the most common general usage. It means to look at something closely to learn more about it, evaluate it, or enjoy it. It is often used when investigating a noise, researching a topic, or visiting a new location.

• "You should check out that new Italian restaurant downtown."
• "I heard a strange noise in the basement; I'm going to check it out."

2. Validity and Consistency

When used intransitively (without an object), it means "to prove to be true" or "to be consistent with the facts." This is common in police investigations, fact-checking, or verifying alibis.

• "His alibi checks out; he was at the movies when the crime happened."
• "I did the math three times, and the numbers check out."

3. Departing a Place of Stay

This refers to the administrative process of settling your bill and leaving a temporary accommodation or facility, such as a hotel or hospital.

• "We need to check out of the hotel by 11:00 AM."
• "The doctor said he can check out of the hospital tomorrow morning."

4. Completing a Transaction (Retail & Libraries)

This usage covers the final step of a process, usually involving paying for goods or officially recording a borrowed item. It is standard in supermarkets, online shopping, and libraries.

• "I’m ready to pay; I’ll meet you at the checkout counter."
• "I went to the library to check out three books on history."

5. Mental Disengagement

A metaphorical usage meaning to lose focus, stop paying attention, or become unenthusiastic. It implies the mind has left the room even if the body is still there.

• "The lecture was so boring that I checked out after ten minutes."
• "He has completely checked out of this relationship."

6. Observing Someone (Often Romantically)

This is informal slang meaning to look at someone intently, usually because you find them attractive. It can also refer to sizing up an opponent in a competition.

• "I think that guy over there is checking you out."
• "He was checking out the competition before the race started."

7. Administrative "Check-Out" (Inventory)

In professional settings, such as IT departments or the military, this refers to officially signing for a piece of equipment so that it is tracked under your name.

• "You need to see the quartermaster to check out your gear."
• "I need to check out a company laptop for my business trip."

8. Euphemism for Dying

A somewhat grim, slang usage (similar to "kicking the bucket"), implying leaving life in the same way one leaves a hotel. This is often found in noir fiction or movies.

• "He lived a long life and finally checked out at the age of 95."

9. The Darts "Checkout" (Winning the Leg)

In the sport of Darts (specifically 501), "checking out" is the critical final phase of the game. To win the leg, a player must reduce their score to exactly zero, with the final dart landing on a double.

• "He needs 170 to check out."
• "That was a magnificent 120 checkout!"

Notice how "check" and "out" are separate when used as a verb but combined into "checkout" when used as a noun. 

Overall I'm happy with this uncomplicated solution to a problem that had been bedeviling me for some time.

CotEditor to the Rescue

Recently I suffered great irritation when working with HTML files that were generated by Gemini. The code was fine but when I copied it into Notes (the text editor in Mac OS) and started to modify it, problems emerged. This is the diagnosis that Gemini made:

Your experience with TextEdit where the file contents "vanished" or where the code was corrupted strongly suggests TextEdit was defaulting to Rich Text Format (RTF).

• RTF: TextEdit is fundamentally a rich text editor. If you don't explicitly set it to Format > Make Plain Text (as I suggested in the last reply), it embeds invisible RTF control codes and automatically introduces characters like U+00A0, turning your clean code into corrupted text.

• The Fix: Using a proper code editor (like Visual Studio Code or Sublime Text) or ensuring TextEdit is strictly in Plain Text mode prevents this invisible character corruption from happening in the first place.

The recommendation of Visual Studio Code was decidly overkill. The interface was far too complex for my purposes and so I complained to Gemini and got this response:

I sincerely apologize for the frustration that Visual Studio Code caused. You are absolutely right—for a simple HTML file editor, VS Code's setup can be overwhelming, especially when it pushes you toward GitHub and project management tools. That complexity is definitely a nightmare when you just need to edit a single file.

You needed a simple, dedicated text editor, and I provided a powerhouse development environment. My mistake.

Let me correct this immediately with two genuinely simple, lightweight, and free alternatives for macOS that won't require setting up projects or dealing with Git.

🛠️ Better macOS Code Editors (Simple & Free)

Both of these options are much closer to a straightforward plain text editor than VS Code, but they include the crucial syntax highlighting necessary for web code.

1. CotEditor 🥇 (Top Recommendation)

• Best For: Users switching from TextEdit who want maximum simplicity and speed.

• Cost: Completely Free.

• Key Features:

  • It's a native macOS app, meaning it looks and feels perfectly integrated with your Mac.

  • It defaults to Plain Text. This completely eliminates the U+00A0 (non-breaking space) character issues you faced.

  • It offers excellent syntax highlighting for HTML, CSS, and JavaScript, making your code readable.

  • It has a clutter-free interface.

• Where to Get It: You can download it directly from the Mac App Store.

2. TextMate (Solid Alternative)

• Best For: A classic, clean text-editing experience.

• Cost: While technically paid, the older version is often used for Free. The official current version offers a free evaluation period.

• Key Features:

  • It was one of the original famous Mac code editors.

  • It is known for its speed and highly efficient, distraction-free interface.

  • Perfect for quick edits to single files like your dashboard.html.

Action: I strongly recommend giving CotEditor a try. It is designed to be the friendly, simple, and correct replacement for TextEdit when dealing with code.

I went with CotEditor and this worked just fine. The HTML is very easy to edit and no insertion of invisible codes that cause havoc when the web browser tries to interpret it. A lesson learned.

Mobile Font Size Problem

This problem relates to my mathematical blog where I've discovered a problem with the font size rendering of LaTeX expressions. It's noticeably smaller than the font size of the surrounding text. I asked Gemini the following question as to how to fix the problem:

In Blogger, my LaTeX mathematical expressions are noticeably smaller than surrounding normal text when viewed in mobile browsers (Chrome, Safari and Brave). However, when viewed in Chrome on my laptop, the LaTeX expressions are larger and similar in size to stringing text. I suspect that this would hold true for other browsers as well although I haven’t tested it out. How can I remedy this problem? 

Figure 1

So far it has failed to solve the problem and I'm thinking that I should try some AI alternatives as Gemini just seems to go around in circles. You'd think that, since Blogger is a Google product, that its AI should be quick to spot a solution but that's proven to be not the case. To be continued. Figure 1 shows the problem. I want the numerals in the LaTeX line: 1, 22, 55, 115, 235, 475, 3389, 13457, 35743 to be larger. It's not a huge problem but it is irritating.

CodeCogs

I noticed that Google Docs was using CodeCogs to render LaTeX into image gifs. CodeCogs at https://www.codecogs.com/latex/eqneditor.php provides an interface whereby LaTeX code can be generated quite easily together with an image of what the code would produce if rendered properly (and therefore to be used when the code can't be rendered properly). Here is the interface:

Figure 1: interface that meets the user on CodeCogs

The code can be copied into a document that interprets the LaTeX code and the result is as shown here --> \( \int_{0}^{1}x^3 dx=\bigg [\frac{x^4}{4} \bigg]_0^1\).

The image produced on the site can be simply dragged and dropped:

Alternatively, the HTML code can be inserted into the web page and the image called up from CodeCogs. The result is the same except for the pop up text box that appears when you hover over the image:

These sorts of services are useful for those who lack confidence in creating LaTeX code but there are limitations to what can be produced. There's no substitute for being able to code directly. One site that provides this facility is Overleaf, an online LaTeX editor. Projects that are created can be stored on the site and printed out if desired. The free plan only allows for solo use, no collaborators. There are paid plans that allow for collaboration and provided additional features such as synching with Dropbox and GitHub, full document history, track changes etc. Of course, if you're using a Mac like me, you can download the free program TeXShop to your computer and simply work from there, no online access required. Questions can be posed and solutions hopefully provided on StackExchange.
