I was skimming through this theme template XML , and I noticed there was the and being used inside the condition of b tag. The last image above, you can see even OR operator is written conveniently as or ! Perhaps that is not new to some of you, but to me, that is NEW! 😄 I do actually implement that to my own logic in the Blogger XML template. But of course, it again depends on the logic. We can do this: if (condition_1) { if (condition_2) { // condition_1 AND condition_2 are satisfied } else { // Only condition_1 (outer) is satisfied } } else { // None of the condition } Or this: if (condition_1 && condition_2) { // condition_1 AND condition_2 are satisfied } else { // None of the condition } Example I mostly implement the second one. So, it's quite convenient to write it like regular coding syntax. For instance, this nesting: <b:if cond='data:blog.pageType == "item"'> ...

Health: Stomach Ulcer and Food Poisoning Quick Treatment

First of all, I'm not a medical doctor. I have an engineering degree in low power electrical field and I am a web developer. 😶 But I do have lots of experiences handling these: stomach ulcer and food poisoning ; for myself and for other people around me. And, of course, I have friends, colleagues, and family who are medical professionals. Mostly medical doctors. Let me share some of quick treatments for stomach ulcer and food poisoning . Stomach Ulcer: The Habit Sometimes, or most of the time, as we get older, we do not take meal with constant periodical cycle like while we were children or teens. But as I've noticed nowadays, teens also have that habit . Our human body can adapt, if you notice, to that kind of punishment . At first, it was probably really hurt, and as the time went by, we no longer feel the pain. It has multiple meanings: Our nerves ( nociceptors ) finally ignore the pain signal because we consciously and constantly pret...

Blogger Conditional Tag — b:if and b:else

Blogger has special b:if , b:elseif , and b:else tags. Those only work if we put them in the XHTML of the Blogger blog, not in the HTML widget (via layout).

Math: (Shortcut for) Simplifying (Denesting) Nested Square Roots

The basic form looks like this: $$√{a ± 2√b}$$ a is $(x+y)$ and b is $(x·y)$ $$√{(x + y) ± 2√(xy)} = √x ± √y$$ Let's go to the methods and examples. PLUS $$√{a + 2√b}$$ $$√{(x + y) + 2√(xy)} = √x + √y$$ With $x > 0$ and $y > 0$ Example $√{7 + 2√12}$ We have $x + y = 7$ and $xy = 12$ Factor pairs of $12$: $1 × 12$ $2 × 6$ $3 × 4$ We pick the last factor pair: $3 × 4$, because $3 + 4 = 7$ We have $x = 3$ and $y = 4$ Therefore, $√{7 + 2√12}$ can be simplified to $√3 + √4$ ➡️ $√3 + 2$ In conclusion: $√{7 + 2√12} = √3 + 2$ ✅ MINUS $$√{a - 2√b}$$ $$√{(x + y) - 2√(xy)} = √x - √y$$ With $x > 0$, $y > 0$, and $x > y$ Example $√{15 - 2√56}$ We have $x + y = 15$ and $xy = 56$ Factor pairs of $56$: $1 × 56$ $2 × 28$ $4 × 14$ $7 × 8$ We pick the last factor pair: $7 × 8$, because $7 + 8 = 15$ But since $x > y$, then we ...

Blogger: How to Implement OR Operation Within b:if Block

We can do logical OR operation using or (keyword) or || (double pipes) in the condition for cond attribute of the b tag, specifically the b:if . For example, we want to show custom content or executing script only on static page OR item (post): [...custom content here...] OR: [...custom content here...] We can put more than two conditions for the OR . condition-1 || condition-2 || condition-3 || ... || condition-N OR: condition-1 or condition-2 or condition-3 or ... or condition-N OR, WE MIX THEM 😂 condition-1 || condition-2 or condition-3 or ... || condition-N That actually works! But it will confuse ourselves. Thus, it is recommended to consistently use either one, the || (double pipes) or the or keyword. Logical AND In latest Blogger XML , we can actually use the keyword and for AND operation. This is a post about that . For more reference regarding b:if , b:elseif , and b:else , this is a post about Blogger Conditional Tag — b:i...

Blogger Template Error Message: "The entity name must immediately follow the '&' in the entity reference"

It means we need to escape the & character with & Example I took a snapshot of an error Replace the character & with & That solves the error. This is a tool on Port Raptor to encode and decode the characters .

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 . It is an application of XML which extends the functionality of HTML so that it can operate with the custom data provided from the server. Such as the <b:widget> , <data:post.title/> , <b:loop> , <b:if> and other Blogger data tags. The string within the <![CDATA[ ]]> (Character Data) section will be interpreted as only character data , not markup. This is the definition . The Forbidden Characters < (less than character) > (greater than character) & (and character) The double quotes (") and single quote (') in Blogger template will be automatically replaced by " and ' , respectively. Usage in Script Tag The script tag (JavaScript) can be placed anywhere in the head or in the body section of a Blogger blog, depends on what's the purpose of that part...

VS Code Thinks atob() Is Deprecated - How to Fix

Actually, both atob() and btoa() . This Is Specifically in VS Code Or VSCode . Because if I said "... on VS Code", that would sound like I was physically standing on top of VS Code, like a skateboard. 🛹 😂 🤔 At the moment, it is a bug 🪲, until it is not 🔧, in their IntelliSense for JavaScript. I noticed it since few years behind. Indeed it is harmless . But since last week, when I opened my certain Node.js project (monolithic — frontend and backend in one project), I kept on noticing the struck through function. And therefore, here's how to fix it. For your information, the JavaScript (ECMAScript) here is the actual browser (frontend / client) language, not backend / server-side (Node.js). But also in this post, we'll see implementation in Node.js. 🤔🙂 This is deprecation notice for atob() : This is deprecation notice for btoa() : Fix: Attach Window Object For atob() window.atob() For btoa() window.btoa() Fixed. 👍 History The met...

How to Fix the ‘No Wi-Fi Networks Available’ Bug on Windows 11 (AMD) Laptops

Good day! This bug specifically on Windows 11 — on laptops with AMD processors, I've noticed. The Issue On Windows 11 laptops with AMD processors, the Wi-Fi adapter sometimes suddenly reports No Wi-Fi networks available — even though the router and ISP are fine, and phones connect normally. Trigger Often happens right after an ISP (Internet Service Provider) hiccup, a brief disconnection, or when waking from sleep. Instead of reconnecting, the adapter seems to freeze and stops detecting SSIDs (Service Set Identifiers) entirely. Cause It's a quirk of Windows 11 combined with AMD-platform Wi-Fi chipsets (often MediaTek or Realtek). The adapter gets stuck in a bad state, so Windows thinks no wireless networks exist. Workaround Instead of installing "latest" drivers and getting confused, we can do this: Check the router first — use your phone to confirm other devices can see/connect to Wi-Fi. Shut down the laptop. Bloody remove (unplug) all the ...
