What is the difference between fault and blame?

Fault is technical. Blame is culpability. If I accidental commit a crime (such as fail to scan 3 items at the store check out and only scan 2) I am technically stealing, and at fault. But I'm not to blame, it was an accident. Not sure if the law makes a legal differential often though.


What is the difference between two phase commit and three phase commit in distributed system?

In computer networking and databases, the three-phase commit protocol (3PC)[1] is a distributed algorithm which lets all nodes in adistributed system agree to commit a transaction. Unlike the two-phase commit protocol (2PC) however, 3PC is non-blocking. Specifically, 3PC places an upper bound on the amount of time required before a transaction either commits or aborts. This property ensures that if a given transaction is attempting to commit via 3PC and holds some resource locks, it will release the locks after the timeout.3PC was originally described by Dale Skeen and Michael Stonebraker in their paper, "A Formal Model of Crash Recovery in a Distributed System"[1]. In that work, they modeled 2PC as a system of non-deterministic finite state automata and proved that it is not resilient to a random single site failure. The basic observation is that in 2PC, while one site is in the "prepared to commit" state, the other may be in either the "commit" or the "abort" state. From this analysis, they developed 3PC to avoid such states and it is thus resilient to such failures.


Questions of law and questions of fact?

Questions of law and questions of fact do not always yield truth. For example if I killed a person because someone else was holding a gun to my head and was going to kill me, I would not be guilty of that crime because the action was committed under duress. The fact is that i did commit the action, but am not liable for the action.


Conversation between a pen and a pencil?

Dialogue Between Pen and Pencil The grass was green as ever, the sun was angry as never. The air was cool enough to touch the skin and relax it. the place where they were sitting was a garden. Both were looking cool and comfortable to face the scene. The day was peaceful, Pen and Pencil were facing each other and the arguments begin as, Pen: You are so unrealistic and overly down to earth. You do whatever people say to you and they manipulate you often. Pencil: People are not perfect and they do make wrong choices and commit mistakes, I am just considerate about them. It is your negative mind that you consider people as deceivers and manipulators, However, I just think that it is self-correction and not manipulation. Pen: Wow! It means my judgment about you is justified. Pencil: What judgment? Pen: That you are unrealistic! Pencil: Oh! come on, People are not always behaving as you think. Tell me what if you had written in your goals that if you could not succeed in some of your commitments, you would commit suicide, wouldn't it be better to erase that commitment? what do you say? Pen: Ahh! people are not silly like that, now you are being negative about people. just see you said. Pencil: Well! what is your purpose of being so strict? Pen: Well, I believe, the value lies in being a man of words. Pencil: I see. But you are dangerous for students then, how can you justify it? Pen: That is simple, maturity and sensibility follow self-confidence, and self-confidence comes through me. Once they answer any question they should be accountable for it. Pencil: True in some sense, but I am a symbol of hope for everyone because they can sharpen me anytime for better results but you have got no such talent. Pen: Ahh! but still, most of the world uses me. Pencil starts crying, leaven the garden with last words as, *I resemble God more than you, As I let people erase their faults which is the sacred attribute of God. Pen: I surrender! Discussion ends! Questions: 1- Which character you support and why? 2- Pencil was using which tactic to persuade Pen? 3- which is your favorite argument in this?

What is the difference between cheating husband to cheating wife?

Cheating is cheating no matter if the woman is married or single. The only difference is the man involved feels he can have a wild affair with a married woman without commitment because she will most likely stay with her spouse and the man cheating will stay with his spouse, but if he should have an affair with a single woman she may want him to leave his wife and commit to her.


What is the difference to commit to god and committed to god?

"To commit to god" is that you have to yet commit your ways to the favour of god and his likings. It is that you have to change your way of life or your choice for God's choice in your life. Whereas "Committed to God" refers to a life which already walks according to the path and will of God. He or she has submitted his or her complete life to The Eternal One and only looks forward to the purpose of God in his or her life.
