## 民主歌聲獻中華 Concert For Democracy In China 1989-05-27

Hong Kong people who grew up under the British rule (before 1997-07-01) generally respects freedom and genuine democracy (the western kind with separation of powers strictly enforced under the rule-OF-law, not Marxist-Leninsts’ People’s democracy which is the dictatorship of the Soviets).

They fought for freedom and genuine democracy in China in 1989 in response to the Tiananmen Square massacre. 30 years later the very same artists were bought by the Chinese Communist Party to relay their propaganda. It’s scary how many people will sell their souls and their freedom, especially other people’s freedoms, for some ‘easy’ cash (those easy cash has strings attached: you have to obey the CCP. It’s a contract with Satan).

The Chinese Communist Party did the same infiltration plans to America, which the Chinese Communist Party has made the break during the Clinton administration bribing American politicians which opens the door for them to WTO and other international organizations, allowing the evil transnational criminal organization Chinese Communist Party to have more access to trade and use the wealth to destroy and dominate the free world with communism. Time for us to either shoot down the communist party or be slaves of Xi Jin Ping.

For those who want to dive into the details, the infiltration plan is called the ‘Termite strategy‘ by Chinese Communist Party premier Zhou-Enlai: basically it sends infiltrators dressing up as innocent members of the society at all levels to emigrate to the victim country that the Chinese Communist Party wishes to corrupt. It goes as early as the 1940s, and the first attempt to subvert is the 1967 riots of Hong Kong. They did something similar with the underground communists worldwide disguising itself as the black rights movements (which repeats itself as the #BlackLivesMatter movement in 2020). There’s no surprise as the Chinese Communist Party has been sticking with the same plans ever since conception. Everything in between are just (like staying under the radar for a period of growth during Deng and Jiang dynasties) the process of helping them gain power to achieve the same evil goals of world domination by communism.

Here’s the playlist of the charity event “Concert For Democracy In China”.

## Nested Ordered List Plugin Conflicts

I recently had problem with Enlighter plugin (for displaying code) being misaligned after upgrading my WordPress. The Enlighter text went outside the boxes in desktop browser mode and I contacted the author of the plugin for help in the forum, and learned it was actually Nested Order List (NOL) plugin that’s overriding the CSS rules that defines the margins.

Another user had similar problem NOL conflicting certain templates and the author of NOL suggested similar causes that the CSS style from the plugin messed with other styles:

.nested-list .entry-content ul,
.nested-list .hentry ul {
margin:.8em 0 .8em 1.4em
}

The author suggested that the NOL plugin itself is not complicated to start with (it’s just adding a CSS), and the same functionality can achieved by adding this CSS to my WordPress theme template (pasting the following text under “Additional CSS”):

.entry-content ol,
.hentry ol {
counter-reset:level1;
}
.entry-content ol ol,
.hentry ol ol {
counter-reset:level2
}
.entry-content ol ol ol,
.hentry ol ol ol {
counter-reset:level3
}
.entry-content ol>li,
.hentry ol>li {
list-style-type:none;
line-height:1.4;
text-indent:-1.5em
}
.entry-content ol>li:before,
.hentry ol>li:before {
content:counter(level1,decimal)'. ';
counter-increment:level1;
display:inline-block;
text-align:right;
text-transform:none;
width:1em
}
.entry-content ol ol>li:before,
.hentry ol ol>li:before {
content:counter(level2,lower-alpha)'. ';
counter-increment:level2
}
.entry-content ol ol ol>li:before,
.hentry ol ol ol>li:before {
content:counter(level3,lower-roman)'. ';
counter-increment:level3
}

It worked like a charm!

## Texas Gov Rick Perry’s response to Craig Ferguson’s honorary citizenship request Standard to become a proud Texan

I fondly remember Craig Ferguson’s skit on his Late Late Show reading a letter from Governor Rick Perry responding to his application to become an honorary citizen of Texas (part of his honorary citizen campaign before he became an US citizen). We hear bits and pieces on the show, but gladly Ed Bark has the whole letter down in his blog.

Since it’s very old material, and it seems such marvelous material is fading out from search engines, I made a copy here to preserve it. I hope somebody can find the letter and make a PDF out of it.

Here’s the letter:

Dear Craig,

There was a time when we granted the status of Texan to just about anyone, including criminals, drunks and Tennesseans. Today our standards are much higher.

We need to know first of all if you have a gun rack on your car — and we don’t mind gun racks on girlie cars, which I suspect you drive.

Secondly, we need to know if, upon approaching roadkill, you drive on by, or stop and throw it in the back so you can skin it and hang the pelt on your wall.

Third, we need to make sure you have never, and never would, deface the Alamo.

Lastly, we need to know if you are willing to stand guard on our border, and prevent the entry of illegals from Arkansas, Oklahoma, Louisiana and New Mexico.

Your citizenship as a Texan depends on your answers to these questions, and whether you can dip tobacco and eat chili at the same time.

Sincerely yours,

Rick Perry

Governor

## System Engineers’ tip to HKCEE/HKALE Math and Physics

Shortly after I’ve graduated with Mathematics and Electrical (and Computer) Engineering degrees, I realized a few supposedly difficult topics in Hong Kong’s Mathematics and Physics (Electric Circuits) curriculum was taught in unnecessarily painful ways.

Here’s an article I’ve written to show that it is less work to teach secondary (high) school students a few easy-to-learn university math topics first than teaching them dumb and clumsy derivations/approaches to avoid the pre-requisitesHKDSE EE Tips

Here are the outline of the article

• Complex numbers with Euler Formula
• Trigonometric identities can be derived effortlessly using complex number than tricky geometric proofs
• Inverting matrices using Gaussian elimination instead of messing with cofactors and determinants
• Proper concepts of circuit analysis and shortcuts
• Solving AC circuits in a breeze with complex numbers instead of remembering stupid rules like ELI and ICE rules and messy trigonometric identities.

## The most important invariants in basic electronics

The two basic laws in circuit analysis, Kirchhoffs Voltage and Current Laws,

1. [KVL] Voltage across the same pair of points is the same no matter what paths you take
2. [KCL] Current stay the same along the same path

are often taught in basic circuit analysis, but most of the time, they taught it in the context of nodal analysis, which you have a little more complicated meshes with multiple theoretical power source (voltage or current) that simple series/parallel circuit rules are not enough to solve the puzzle.

However, these two fundamental concepts are useful to develop insights that help you estimate quantities in a circuit quickly like a pro.

Kirchhoffs Voltage Law [KVL] can be applied to a parallel circuit of 2 branches (often the case when measuring additional loading effect). Let say the two branches are applied (loaded) at a voltage output , which might change depending on the branches (loading).

You can exploit the algebra to quickly calculate the current of any branch without first computing the overall resistance or current:

Kirchhoffs Current Law [KCL] is useful in analyzing energy loss over resistance in wires . For example, in high school physics, we discuss why we have high voltage power lines for bulk energy transmission despite it’s more dangerous. The traditional explanation is

so the lower the current is (which can be done through stepping up the voltage, traditionally done with AC signal through transformers, to maintain the same power). But how about other form

Technically, it’s possible, but you have to be very careful that the voltage we are talking about is across the wire with resistive losses , NOT the load voltage .

changes depending on the output load , so you have to derive the assuming an arbitrary , which will happen to cancel itself out and end up the same as if you think of everything in terms of current first:

So the bottom line is that most of the time, it is easier to think in terms of current in most circuit analysis because current won’t change along the same path. This is especially true when your problem has varying impedances/load which will disturb the voltage.

Of course, if the problem screams direct application using KVL, don’t go all the way converting it back to current. You will find the current-first approach useful when we get to semiconductors like diode, voltage references, BJTs,.

I usually think of voltage as a consequence or effect of current flushing into a transducer (e.g. resistor), so it’s subjected to change and therefore messy to use when solving circuit puzzles. Solving circuit analysis problems are often an exercise of identifying invariants and inferring the remaining quantities.
