hardware – General: firmware reversal

I am no expert on the subject, I am only interested

I saw a video on extracting firmware via JTAG, and
finished with the airplane file system, okay!

but then what? why all of this?
what can i do with the file system?
I'm looking for something that interests me, but only
get to the point of having the file system

My sincere thanks for your answers and your time

Google Analytics tracking conversion, but not general traffic

Have two sites: diffy.website and the app itself app.diffy.website. I would like to track visitors to diffy.website but conversions from the app. I have set up cross-domain tracking, but I also get traffic accounts from the app. What is the best way to filter visits to my application but to keep conversion events?

What types of links are most useful? – SEO help (general chat)

A dofollow link is the most valuable type of link because it transmits SEO value and SEO authority to the site to which it leads. dofollow connections are active hyperlinks with anchor text (text that is a hyperlink) that is usually linked to the name or subject of the content or the campaign publisher.

What is the difficulty of the keywords? – SEO help (general chat)

Keyword difficulty (or keyword competition) is a critical measure for keyword research. The higher the value, the more difficult it is to compete with others using this keyword. … focus on weak competition keywords is the secret ingredient to SEO success.

general topology – The existence of a countable dense subset of a non-empty compact network of $ mathbb {R} ^ {n} $

I read about Tarski's theorem in the lecture note:

enter description of image here

In the proof of Lemma 2.13, the author said that

Let $ D = left {d_ {1}, ldots, d_ {n}, ldots right } $ be a dense (finite or) countable subset of $ A $.

Could you explain the existence of $ D $? Thank you so much!

Precalculation algebra – Why is the series with the general term $ sqrt {n ^ 2 + 1} – n $ divergent?

Test the series whose general term is: $$ sqrt {n ^ 2 + 1} – n $$

It is from Upper algebra by Henry Sinclair. I'm having trouble understanding how this series is divergent. If you do the following extension:
$$ sqrt {n ^ 2 + 1} – n $$
$$ = n biggl (1 + frac {1} {n ^ 2} biggr) ^ frac {1} {2} – n $$
$$ = n + frac {1} {2n} – frac {1} {8n ^ 3} + … – n $$
$$ = frac {1} {2n} – frac {1} {8n ^ 3} + … $$

The remaining series seems to converge to zero while $ n $ is approaching infinity.

Their explanation is similar to mine, but in the end they say the above series is approaching $ frac {1} {2n} $. From there, they directly say that the series is divergent. Earlier in the chapter, it was proven that the expansion of $ (1 + x) ^ n $ is convergent for $ x <$ 1. In that case, $ frac {1} {n ^ 2} <1 $ as $ n $ is approaching infinity, so I guess the series is converging.

The solution to the problem is given here (number 17)

Any help is appreciated. Thank you.

Fear of Death – SEO Help (General Conversation)

Fear of death

The fear of death is a reflection of an inauthentic fear. Fear is forged because people understand that one day they will certainly die. However, what causes fear of death? The fear of death is caused by ignorance of what is before and behind death but not death itself. What awaits us after death remains a mystery to most people and, at best, speculation. Nevertheless, religious scriptures mention life after death. Therefore, it is the individual's choice to believe or not to believe in life after death. Behind death, fear is caused by unwanted people from losing the social attachments created before the time of illness. When an individual is attached, a fear develops that one day it will cause pain. These attachments include friends, family, relationships, material goods, circumstances and even the body. The process of death attracts the attention of many researchers. Nonetheless, the Kubler Ross death model is one of the widely accepted and emulated models. The document will explore the phenomenon of death in relation to the Kubler-Ross model.


Death is a personal journey that each individual approaches in a unique way. There is nothing certain about death as there are many paths leading to death. When a person approaches death, a death process that begins on the mental path of discovery and understanding that death will occur makes one believe in one's own mortality. As a result, the journey ultimately leads to a physical exit from the body. Kubler-Ross instituted the dying process hypothesis in his work entitled On death and death based on his experience with incurable patients. Powered by limited medical training on the subject, Kubler-Ross developed a concept of the process of death that remains popular to explain the process of death.

According to the five stages of Kubler-Ross' death, the first stage involves denial. The person ignores the facts of the death, turning into a lie. This includes lying by omission or exaggerating the facts in order to alleviate the pain. People who take this step avoid all aspects of personal liability by minimizing, justifying and blaming. The ultimate goal is usually to divert attention from oneself. In addition, denial is characterized by denial of denial. This involves a form of denial of self-delirium that involves behavior and actions that hide a person's true grief. Behaviors deceive others into believing that everything is fine.

In the next phase of the process, the individual realizes that the denial cannot continue. As a result, anger takes over and the person strives to hold everyone accountable. Anger is directed against friends, family members, yourself, or God. It is essential to note that anger during this period does not have to be valid or logical. Anger arises from the inability to stop the suffering that ultimately leads to death. According to Kubler-Ross, anger occurs when an individual does not feel safe and certainly will not survive whatever happens. Kubler-Ross further notes that the angry person is usually very difficult to care for due to misplaced feelings of envy and rage. However, it is essential to keep your judgment when taking care of people undergoing this stage.

The third stage gives hope that death will be delayed or postponed. This involves attempts to negotiate an extension of life made with God in exchange for an improved lifestyle. Psychologically, a person understands that he will eventually die, but negotiates just more time through negotiations and compromises. However, such negotiations can rarely resolve the problem specifically in matters of life and death. The negotiation style often occurs when the person is on the verge of death. Survivors try to negotiate with supernatural powers in order to save lives. In most cases, people at this stage seem desperate, so false hope is discouraged.

In the fourth stage, depression occurs when the person understands the inevitability of death. As a result, the individual is silent, avoids the guests and spends a lot of time crying and crying. In addition, it makes the dying

person disconnected from affection or love. Depression also indicates that the dying person has gradually begun to accept the fate to come. This stage leads to an intense feeling of guilt, the concern of dying and suicidal thoughts. In addition, this results in slow movements and speech, as well as tendencies to stay in bed all day.

At the fifth stage, the dying man accepts the certainty of death. The urge to continue fighting decreases. Although this process takes a long time, most people undergoing the grieving process learn to accept death. Nevertheless, acceptance does not mean that the individual agrees with the situation or that he returns to normal life. An individual accepts that life will never be the same again, thus learning to live with the situation. He / she presupposes that God can be nonexistent and only waits for the time of death. This step provides the individual with a time to establish peace with family members and friends. In conclusion, it is obvious that death is a process that takes some time before the ultimate end. Excluding accidental deaths, deaths resulting from a terminal illness can be defined by the model. Therefore, it is essential to provide supportive care for the dying person. Counseling and therapy should be conducted in order to prepare the individual to go through the stages with little difficulty.

general topology – Application of a function to an indexed filter family, are two formulas equal?

Let $ f $ be a function (possibly with multiple values).

I will denote $ langle f rangle mathcal {X} = bigvee ^ { mathfrak {F}} _ {X in mathcal {X}} f (X) $ for each filter $ mathcal {X} $ or $ bigvee ^ { mathfrak {F}} $ is the join on the filter stand (on the domain set of $ f $) ordered by inclusion. (He still exists.)

I will define reloidal product of an indexed family $ mathcal {X} $ (on the tray $ operatorname {dom} mathcal {X} $) filters this way:

$ prod ^ { mathsf {RLD}} mathcal {X} = bigvee ^ { mathfrak {F}} _ {X in prod mathcal {X}} prod X $ (intuitively: as a continuous extension of the Cartesian product of sets, $ prod X $ designates a Cartesian product of the indexed family $ X $ d & # 39; sets).

Equivalently, $ prod ^ { mathsf {RLD}} $ is the filter defined by the filter base $ lbrace prod X mid X in prod mathcal {X} rbrace $.

I will define reloidal starry product ("inspired" from ananlogy with Tychonoff produces topological spaces) from an indexed family $ mathcal {X} $ filters this way:

$ prod ^ { mathsf {RLD} ast} mathcal {X} $ is the filter defined by the filter base

$ lbrace prod_ {i in n} (A_ {i} text {if} i in m text {or other} mho) mid m text {is a finite subset of} operatorname {dom} mathcal {X}, A in prod (a | _ {m}) rbrace $

or $ mho $ is a fairly large ("universal") set.

The question: are the following two expressions always equal:

  1. $ langle f_y rangle prod ^ { mathsf {RLD}} mathcal {X} $

  2. $ langle f_y rangle prod ^ { mathsf {RLD} ast} mathcal {X} $.

Here $ f_y $ is the function (with multiple values) $ f $ considered as a function with a single argument taking as an argument the indexed families.

(These two elements are two different ways of applying multi-argument functions to families of indexed filters.)

The question appears naturally in my research entitled General Algebraic Topology and is important for manipulating the generalized limits of arbitrary functions.

Proving it without knowing my theory can be difficult, but I expect the crowd of mathematicians to find a counterexample against this equality. Note that it is known that there is no counterexample if $ operatorname {dom} mathcal {X} $ is finished. So please look for an infinite counterexample.
