Give an example of a deadlock taken from politics.

Question 2
Page 465, Problem 5:

The four conditions (mutual exclusion, hold and wait, no preemption and circular wait) are necessary for a resource deadlock to occur. Give an example to show that these conditions are not sufficient for a resource deadlock to occur. When are these conditions sufficient for a resource deadlock to occur?

Question 3
Use the script file sub discussed on the last page of this weeks handout as a template to complete the following tasks:

Follow these steps:
Make two more copies of file mysedfile as mysedfile2 and mysedfile3;
Create a script file, mysedscript, that will read the files, mysedfile, mysedfile2, and mysedfile3, as its inputs using a for-loop;
For each file mysedscript reads, use sed commands to 1) remove the blank line(s), 2) insert the following record before Jerrys record, and 3) update the files accordingly:
Allen 91 83 95
After making mysedscript an executable file, run it. Please verify if mysedfile, mysedfile2, and mysedfile3 are updated as required
Question 4
Based on the data file mysedfile you created for Lab 6, please complete the following tasks:
Create a sed script file mysedprog (see the Linux handouts for examples), that removes blank line(s), appends the following two records after Toms record, and sends the updated information to screen:
Cindy 85 94 92
Allen 91 83 95

Sample solution

Dante Alighieri played a critical role in the literature world through his poem Divine Comedy that was written in the 14th century. The poem contains Inferno, Purgatorio, and Paradiso. The Inferno is a description of the nine circles of torment that are found on the earth. It depicts the realms of the people that have gone against the spiritual values and who, instead, have chosen bestial appetite, violence, or fraud and malice. The nine circles of hell are limbo, lust, gluttony, greed and wrath. Others are heresy, violence, fraud, and treachery. The purpose of this paper is to examine the Dante’s Inferno in the perspective of its portrayal of God’s image and the justification of hell. 

In this epic poem, God is portrayed as a super being guilty of multiple weaknesses including being egotistic, unjust, and hypocritical. Dante, in this poem, depicts God as being more human than divine by challenging God’s omnipotence. Additionally, the manner in which Dante describes Hell is in full contradiction to the morals of God as written in the Bible. When god arranges Hell to flatter Himself, He commits egotism, a sin that is common among human beings (Cheney, 2016). The weakness is depicted in Limbo and on the Gate of Hell where, for instance, God sends those who do not worship Him to Hell. This implies that failure to worship Him is a sin.

God is also depicted as lacking justice in His actions thus removing the godly image. The injustice is portrayed by the manner in which the sodomites and opportunists are treated. The opportunists are subjected to banner chasing in their lives after death followed by being stung by insects and maggots. They are known to having done neither good nor bad during their lifetimes and, therefore, justice could have demanded that they be granted a neutral punishment having lived a neutral life. The sodomites are also punished unfairly by God when Brunetto Lattini is condemned to hell despite being a good leader (Babor, T. F., McGovern, T., & Robaina, K. (2017). While he commited sodomy, God chooses to ignore all the other good deeds that Brunetto did.

Finally, God is also portrayed as being hypocritical in His actions, a sin that further diminishes His godliness and makes Him more human. A case in point is when God condemns the sin of egotism and goes ahead to commit it repeatedly. Proverbs 29:23 states that “arrogance will bring your downfall, but if you are humble, you will be respected.” When Slattery condemns Dante’s human state as being weak, doubtful, and limited, he is proving God’s hypocrisy because He is also human (Verdicchio, 2015). The actions of God in Hell as portrayed by Dante are inconsistent with the Biblical literature. Both Dante and God are prone to making mistakes, something common among human beings thus making God more human.

To wrap it up, Dante portrays God is more human since He commits the same sins that humans commit: egotism, hypocrisy, and injustice. Hell is justified as being a destination for victims of the mistakes committed by God. The Hell is presented as being a totally different place as compared to what is written about it in the Bible. As a result, reading through the text gives an image of God who is prone to the very mistakes common to humans thus ripping Him off His lofty status of divine and, instead, making Him a mere human. Whether or not Dante did it intentionally is subject to debate but one thing is clear in the poem: the misconstrued notion of God is revealed to future generations.

Question 1: Example of Deadlock in Politics

An example of deadlock in politics can be seen in situations where two political parties within a governing body have opposing views on a critical issue and cannot reach a compromise. This can result in a stalemate where no decisions or progress can be made, leading to a deadlock that hinders the functioning of the government.

Question 2: Conditions for Resource Deadlock

The four conditions for a resource deadlock (mutual exclusion, hold and wait, no preemption, and circular wait) are necessary but not always sufficient for a deadlock to occur. An example where these conditions are not sufficient for a deadlock is when a preemptive resource allocation policy is in place. In such a scenario, even if the other conditions are met, the ability to preempt resources from one process to allocate them to another can prevent a deadlock.

These conditions are sufficient for a resource deadlock to occur when all processes involved hold resources while waiting for additional resources, leading to a situation where each process is waiting for a resource held by another process, creating a circular dependency that cannot be resolved.

Question 3: Script File Tasks

To complete the tasks related to the script file using sed commands, the following actions need to be taken:

1. Create copies of mysedfile as mysedfile2 and mysedfile3.
2. Develop a script file named mysedscript that reads mysedfile, mysedfile2, and mysedfile3 using a for-loop.
3. Within the script, utilize sed commands to remove blank lines, insert the record “Allen 91 83 95” before “Jerry’s record,” and update the files accordingly.
4. Make mysedscript an executable file and run it to verify if mysedfile, mysedfile2, and mysedfile3 are updated as required.

Question 4: Tasks Based on Data File

To work with the data file mysedfile:

1. Create a sed script file named mysedprog that removes blank lines, appends the records “Cindy 85 94 92” and “Allen 91 83 95” after “Tom’s record,” and displays the updated information on the screen.
2. Execute the mysedprog script to apply the specified modifications to the data file and view the updated content as per the requirements.
