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.

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...

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 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).

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...

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...

How to Clear Notepad's Tab State on Windows 11

A very good day to you. 🎩 Straight to business, then. On Windows 11, the path for Notepad tab state is: %LOCALAPPDATA%\Packages\Microsoft.WindowsNotepad_8wekyb3d8bbwe\LocalState\TabState Close the Notepad first. ➡️ Delete all .bin files inside that folder. ➡️ Open again Notepad. No, it won't break the Notepad. Promise. We can set Notepad's start-up option to Open in a new window (instead of "Open in a new tab") after that, optionally. Click the top-right gear icon in Notepad, and we would see this: Through Script We can do it from PowerShell: $folder="$env:LOCALAPPDATA\Packages\Microsoft.WindowsNotepad_8wekyb3d8bbwe\LocalState\TabState"; if(Test-Path $folder){Remove-Item "$folder\*" -Force} Or CMD (Command Prompt): set folder=%LOCALAPPDATA%\Packages\Microsoft.WindowsNotepad_8wekyb3d8bbwe\LocalState\TabState && if exist "%folder%" del /q "%folder%\*" Background I was helping a friend to ...
