IP Addresses Range

I'd often wondered/confounded by the /32, /24, /16, etc. appearing after the ip addresses. Now it is clear.

DD-WRT Block ip, subnet

iptables -I FORWARD -d 58.108.0.0/16 -j DROP

Blocks all ip: 58.108.*.*

Despite many commands suggested to block ip, the above appears to work best. FORWARD, not INPUT.

Unless, of course, I was misled by coincidence where just after executing the command, the 58.108.*.* flooder/hacker decided to stop at the moment.

Rule of Law vs. Rule by Law: The Kim Davis Case & Discrimination

In cases such as this, the term discrimination often comes up.

However, which is Rule by Law? Davis or the supreme court?

Rule of Law: Law is Law.

Rule by Law: Ruler is Law.

Now, back to the discrimination. I have a conclusion after listening to the accusation against Christians and the likes of discrimination. Those who shout discrimination the loudest, are perhaps the ones discrimination others, ie. those whom they accuse of "discrimination".

The Ignorance of Science

Science has two extremes that touch each other:

The first is pure natural ignorance. The other is where great souls arrive after traversing all that can be learned by man, to find that they know nothing.

Those in the middle, who've overcome natural ignorance but not yet attained the other, "the ignorance of the wise", have a smattering of science and act knowing. They are the ones who spread confusion and misjudge everything. ~Blaise Pascal

Flaws of Trinity Illustrations

Here are as many collections of human illustrations of the trinity and their flaws. The best understanding of basic trinity concept is via the Shield of the Trinity (There is only 1 God in 3 persons - the Father is God, the Son is God, the Holy Spirit is God; The Father is not the Son nor the Holy Spirit, the Son is not the Holy Spirit). However, there are those who believe themselves more creative. I shall list them here, and note the danger of their illustrations, which is either modalism/sabellianism (1 God in 3 forms) or tritheism (3 gods).

  • . 3 forms of water: gas, liquid, solid.
    Flaw: in gas is the same in liquid and solid form (Modalism).
  • the Sun's being, light, heat.
    Flaw: Light and heat are not the Sun itself (Tritheism).
  • flower's shape, color, smell
    Flaw: None are actually the flower (tritheism).
  • 1 x 1 x 1 = 1
    Flaw: 1 x 1 x 1 is not 3 (modalism); 1 + 1 + 1 = 3 (tritheism). 1 x 1 x 1 x 1 = 1 (quadrinity issue). Further confusion: (possibly docetism). However, the simplicity of 1 x 1 x 1 can be used to refute addition as necessity, though not enough to go on from there.
  • Copies of the Bible
    Flaw: quadrinity issue.

On translators

I admire good translators. But not when it is from Mandarin to Cantonese or any other Chinese dialects for that matter.

A good translator doesn't just find precise words, but simple sentences as well. A live translation that's often longer than the original language in time is always bad, regardless of clarity.

The City College CUNY Class: MATH 32300 Advanced Calculus

Prof. Thea Pignataro

Recommended higher level reading: Introductory Real Analysis, Kolmogorov & Fomin

Also recommended any Dover Books (good classic texts)

Review Chapter 1 as MATH 30800

Remaining notes by prof. online: http://1drv.ms/1KlFihR

It seems that most parts of advanced calculus is about proving things taken for granted in previous calculus classes. There should be indication of this in the beginning of calculus class, so I don't have to waste my time figuring out those proofs myself back then.

Better Foreign Language Learning Program

Once, everyone thought Rosetta Stone's pedagogy was the best. However, I learned that it contains inaccuracy when I apply what it taught me in real conversation.

Then, I gather that listening to songs of foreign languages was more helpful. Now, there are many songs or methods that apply dual subtitles to help one understand the content and learn the original language.

Now, there is Memrise (Android app - iOS app's audio is faulty at the moment), which is by far the greatest pedagogy in learning most anything that pertains to one's memory.
