Tạo một project web (tự phát triển, có thể trên php, .net, hay java..) theo yêu cầu sau: Website cho phép quản lý danh sách bài tập lớn/đồ án (đặc trưng của một đồ án gồm tên, mô tả, GVHD, file word/pdf, file zip source code, ...) với tính năng hiển thị danh sách, thêm, sửa, xoá...
Dữ liệu lưu trong cơ sở dữ liệu sql server hoặc my sql hoặc hệ quản trị mà sv quen thuộc
Xây dựng hệ thống api tương ứng cho các tính năng trên để khi cần có thể kết nối qua app mobile/ phần mềm desktop...

Write a method so that the main() code below can be replaced by the simpler code that calls method original main(): public class calcmiles { public static void main(string [] args) { double milesperhour; double minutestraveled; double hourstraveled; double milestraveled; milesprhour = scnr.nextdouble(); minutestraveled = scnr.nextdouble(); hourstraveled = minutestraveled / 60.0; milestraveled = hourstraveled * milesperhour; system.out.println("miles: " + milestraveled); } }

Develop a function to create a document in the mongodb database “city” in the collection “inspections.” be sure it can handle error conditions gracefully. a. input -> argument to function will be set of key/value pairs in the data type acceptable to the mongodb driver insert api call b. return -> true if successful insert else false (require a screenshot)

When making changes to optimize part of a processor, it is often the case that speeding up one type of instruction comes at the cost of slowing down something else. for example, if we put in a complicated fast floating-point unit, that takes space, and something might have to be moved farther away from the middle to accommodate it, adding an extra cycle in delay to reach that unit. the basic amdahl's law equation does not take into account this trade-off. a. if the new fast floating-point unit speeds up floating-point operations by, on average, 2ă—, and floating-point operations take 20% of the original program's execution time, what is the overall speedup (ignoring the penalty to any other instructions)? b. now assume that speeding up the floating-point unit slowed down data cache accesses, resulting in a 1.5ă— slowdown (or 2/3 speedup). data cache accesses consume 10% of the execution time. what is the overall speedup now? c. after implementing the new floating-point operations, what percentage of execution time is spent on floating-point operations? what percentage is spent on data cache accesses?
