Please see the attached Requirement.docx, DB1.sql, Prices.rar (this rar file has Prices.sql) The code has to fetch the symbols from the CSV file and then the associated values for those symbols from the DB (lets name this DB as "DB1" - Attached File - DB1.sql) into an dynamic multi-dimensional array in memory. This dynamic array needs to check the against another DB (let's call this DB as - "Prices" - Attached File - Prices.sql) for certain conditions. For example: In the CSV file (Attached file - Symbols.csv) 'SBIN' symbol is stored in the first row of the CSV file, thus it takes the symbol name from the CSV file, and fetches the values (for a particular date) of that symbol from DB1 into a dynamic multidimensional array and then, it needs to check the values in the Prices DB for that particular symbol (for a particular date) against the values stored in the multidimensional array for that particular symbol. Similarly, for all other symbols present in the CSV file, I would need the code to fetch values of those many symbols (for that particular date) into a multidimensional array and check against Prices DB (for that particular date). Detailed Explanation: 1) In the above screenshot of the CSV File, the array size is determined by the number of rows ( 13 rows in the CSV file. The array size can increase or decrease). Say, the array dimension would be array[x][y], where x is 13 and y is determined from the columns in DB1 for that symbol on that date (for that particular date). 2) After storing the values in the array for the chosen/particular date, we need to check the values in this multi dimensional array against the TickPrice column of Prices DB (attached) simultaneously for all the values of that symbol for that Pdate. The conditions that need to be check are : • If we consider the first symbol of the multi dimensional array i.e. SBIN, we would need to check the following conditions : - See Requirement.docx for conditions This above conditions need to be checked for all the symbols that are present. For example, the 2nd symbol in the CSV is ACC, so ACC would have 2nd position in the multidimensional array (i.e. array[2]), and, we would need to check the following conditions: - See Requirement.docx for conditions Similar step has to done for as many symbols are present in the CSV file.

The company is launching a solution in the marketplace of providing safety for children and seniors through a watch (which is also a phone) with the end-user primarily being a parent for the child and a guardian for the senior. The application the company is going to bring to market will register, track and monitor the watch (and therefore the wearer of the watch). The core features of the application include allowing a user to register watches, managing permissions to control which contacts are included both for inbound and outbound calls to the watch. There are also Geofence (enhanced GPS) features and alerting which can be managed from the application. The application will need to be built for both iOS and Android and we are discussing some of the features being accessible through a browser. Duration: we anticipate the app to be developed in approximately 90 days. There is a design and spec in place. However, there will be ongoing work beyond that if things work well with the candidate. Responsibilities include: • Delivering a completed application for our company for the consumer market; • Ideally, though not necessarily, it is built responsively so at to function for both mobile devices and the web, must work for both iOS and Android; • Following a functional specification delivered from our company and turning into a well-documented technical specification; • Writing all code for the application in a timely way according to deadlines and milestones agreed upon with our company; • Combining all elements of the app design, including database schema and interactivity with cloud database, and testing it utilizing the best practices in bug and regression testing; • Testing sample data-sets to check that output from the app works as intended; • Installing the app into the appropriate production environments as necessary; • Reacting to problems and correcting the app as necessary; • Adapting the app to new requirements, as necessary; • Taking part in user-acceptance testing to ensure the app can be used easily, quickly and accurately; • Working as part of a team; • Evaluating and increasing the app's effectiveness. Compensation structure: open to discussion of hourly or project work. Candidate should have: - 5+ years of experience in delivering mobile apps; - Samples of apps to demonstrate; - References for completed apps. - Preferably, but not necessarily, the candidate will be based in Dallas and be able to - work with us from our Dallas based office. Candidate must possess great verbal communications skills.

1- xv6 OS has a RR scheduling, and I want to change it to priority-based. 2- I want to test the performance after the implementation finishes. 3- I want the project to be documented and commented. We will replace the original algorithm for xv6, a naïve and simple round-robin scheduler (as in Figure 1) with a priority-based (as in Figure 2), preemptive one, and then compare the performance between these two algorithms. The operating system will assign a fixed priority to each process. Higher priority processes will be given the privilege of preempting any lower priority processes that are already running in addition to being scheduled before lower priority tasks. Our goal is to achieve an improvement in performance of xv6 with a priority-aware scheduler. Our choice of scheduler came down to a few major factors: first, this sort of scheduler is reasonably well documented and we have plenty of resources and examples to look at while conducting our own research; second, compared to some scheduling algorithms this one seemed to us to be reasonably simple while still being realistic and useable in a real-world operating system; and lastly, the priorities may be varied fairly easily in order to open more doors for experimentation. For example, once the prioritization is implemented in the scheduler, we can vary the priorities of user-facing and background tasks in order to determine which settings are the best for responsiveness to the user whenever the system is fairly busy. We will also be able to measure how prioritization in the scheduler can affect the running time for repeatable jobs that we explicitly give a high priority to in comparison with those same jobs running on a busy machine with the round-robin scheduler. it uses QEMU, a generic and open source machine emulator and virtualizer and Unix terminal commands are required including the GNU Compiler Collection, the linker and assembler distributed with the GNU binutils package, and the GNU Make utility.

I'm looking for a developer with solid experience developing native mobile applications. The specifications of the project are fully elaborated and the designs are almost finished. Targets are iOS and Android, so the best applicant can develop both, but the job can also be split. The application has about 12 screens, and each screen has a low/medium complexity (Log in, registration, profile page, calendar, map, splash screen, ...) You need to know how to integrate a payment gateway (preferably Stripe).
