aaa is  [____________________], bbb is [_____]

We want to construct a box whose base length is 5 times the base width. The material used to build the top and bottom cost $3 per square feet and the material used to build the sides cost $2 per square feet. If the box must have a volume of 100 cubic feet determine the Width that will minimize the cost to build the box. (Note: The dimensions are specifically defined so that which dimension is the width is not ambiguous!)

Potpourri-2a Potpourri (2a) [2 points] (Answer True/False with justification)  By favouring scheduling latency for time-sensitive tasks, TS-Linux could starve throughput-oriented tasks from making forward progress. 

Failures_and_Recovery_3 LRVM Give one pro and one con for the “no_flush” mode in end_transaction.

Failures_and_Recovery_7 Quicksilver In Quicksilver, assume the following:  There is a file server, which talks to a directory server for mapping a client’s file name to an index node that contains the disk block addresses for the file;   The directory server talks to a data server that manages the allocation of disk blocks to store the file contents.  A client opens a file and starts writing to it. The directory server crashes in the middle of the file write by the client. Mention any two possible inconsistent states that may result by identifying the breadcrumbs that may have been left behind due to this crash.

Real_time_and_Multimedia_3 PTS Your friend is a geologist who studies earthquakes and tsunamis. They have placed 1000 seismograph sensors all around the world. Each sensor produces a 1 kilobyte datapoint every second. They have also placed 50 cameras in coastal areas around the world that record at 60 frames per second. Each video frame is 1 MB.  Your friend wants to record this data and analyze it for two purposes:  To send urgent alerts when multiple sensors in a region report strong shaking in the same brief time window. To correlate timestamped video recordings with timestamped seismograph data in order to study what types of shaking cause tsunamis. Is PTS a good basis to build a system for analyzing this data? Justify your answer. 

Failures_and_Recovery_6c Quicksilver The context for this question is same as previous. You are designing a distributed database system on top of the Quicksilver operating system. The system allows clients to perform “read” and “write” operations on data stored across multiple nodes. Each operation generates a transaction tree for recovery purposes. For persistent changes made during a “write” operation, what cleanup protocol would be appropriate? Why?
