The science/tech helping stand.

[Kurisu-Chan]

Hello, and welcome everyone, i hope this sub is the best place for this thread.

Well, i think everyone here knows me....who am i joking, everyone forgot about me, well, it's been aprox 4 years (i'll make a 4 year  thread for that) and there's something i'm obsessed with : helping people and getting helped by them.

For that, i'm creating this little corner of help for everyone to come here and help out, it's not my thread, it's everyone's thread.

This is a community helping thread, which means everyone can participate to the well being of this corner, the basic premise is simple : 

User A asks a science/tech related question (for example, "is it possible to send a message to the past?")

Then, anyone who wants to answer the question will quote User A and give his personal answer.

Helping each other is the motto of the thread, so i'm praying for its success.

I just hope i'm clear enough, and if you have questions...Well, it is the place to post them and get answers, as well as simple leisure while helping each other.

Reformulating the principle of the thread

Why do some people prefer company bonds over buying shares? If a company was to collapse good luck getting your bond back. Is it for the interest you get throughout the years of the bond contract?

[Inorin]

looks like the code function on fuwanovel will be much more useful now 

#include <stdio.h>
int main()
{
printf("Hello World.");
return 0;
}

Good luck getting your shares investement back if a company collapses :p. With stocks you do own a bit of the company and can have some earnings depending on profit (or have no earnings at all), but with bonds you get interest pays which is not limited to profits (it may be smaller but its stable), not to mention that at bankruptcy companies are obligated to pay back bond investors and other creditors first and foremost, only afterwards stock holders, so in a way they are safer.

Well, thanks for the question, that would illustrate what this thread would be used for.

First of all, investing in bonds means you are investing in the debt obligation of a bond user, your are basically lending money in return for the promised repayment of the principal amount at maturity and an agreed upon interest payment, whereas when you invest in shares, you become part owner of the business.

Now, why do people prefer bonds over buying shares? i'd say mostly because of this :

-Returns bonds are not tied to performances or profitability of the business, you'll receive the same returns regardless of the company's well being, even when the company have to restructurate or face a cyclical downturn.

-Many investors use bonds as a way to guarantee their entire principal even as they seek returns to grow their wealth. This can be important for investors who require the money for a future expense such as a child’s tertiary education or to upgrade their home in the coming future.

-steady and visible flow of income. This is especially attractive for investors nearing retirement and seeking passive income to replace their earned income(aka it's a stream of free cash).

-Bond investors do not have any rights to a company’s profit as they are not equity owners, but they do have rights to the assets of an organisation in the event of a default, if the company is in default, they may have to sell their assets, and bond investors are priorized in such case.

 

Naturally, lending money to different entities means you are exposed to differing levels of risk, generally, you should go for government-funded bonds, as they happen to be way safer than corporate bonds.

I hope i answered your question well, and i also hope everyone got the principle of this thread.

Which of the following viruses tries to hide from anti-virus programs by actively altering and corrupting the
chosen service call interruptions when they are being run?

A.
Cavity virus

B.
Polymorphic virus

C.
Tunneling virus

D.
Stealth virus

One site says it's C and another says it's D. What's the correct answer? I mean, don't they both try to hide from antivirus programs? I'm confused

I dunno, but let me add another one on top of it. 

Is there a difference between accurately making predictions about the world and really understanding how the world works? 

I don't know in other fields, but in physics, as soon as you have a theory that matches your experimental data and correctly predicts the result of future experiments, you are done. At least until some weird result shows up and you have to elaborate yet another theory that accounts for that particular case. Does this process ever stop? And even if it does, do you think that plugging in some numbers in an equation and getting a result is the best we human beings can hope to understand the machinery of the universe? Because all of modern physics works that way... You can only "understand" it and work with it via mathematics, where the interpretations are left as a philosofical matter. And you know... Past tells us that philosophy always tackles those questions for which science is not yet prepared. The thing is, will it ever be?

Good science does.

Because scientists actually try to demonstrate and test things, not pull shit out of their asses, like gurus, religion and pals.

As far as I can tell (but I'm not security expert, just an amateur programmer and malware enthusiast) all tunneling viruses are stealth viruses, but not all stealth viruses are tunneling. The correct answer as it's described by the question would be C for me.
