Day #185

Problem 1: Incorrect Grade Report

There could be two causes to this problem, one could be human error and the other would be machine error. Human error could be a mix up or a wrong computation by the teacher. It can also be the mistake of whoever is encoding the report card. Machine errors could be that the grading system that was coded to the computer was changed, miscalculated the grades, and resulted to a incorrect general weighted average (GWA). Another can be there could have been an error in the system or the processing unit.  source source 



Problem 2: Suspicious Charges


There are four things to take whenever you encounter a suspicious charge on your credit card. First, check for unauthorized charges and continue monitoring your accounts. Checking on your transactions as frequently as possible can help in identifying suspicious charges as they can appear months after the data breach happened. Second, report a suspicious charge immediately. Report even the small problems right away. Often times, thieves process a small charge against you account and take more on future transactions. Third, cancel your card and have it replaced before more transactions happen. Changing you PIN is also very helpful in preventing more suspicious charges to come through. Last, but definitely not the least, contact the the management and the police to prevent future suspicious transactions. source


Problem 3: Software Installation Trouble

First remove files of earlier installations and ensure the user account has administrative privileges to install software. Second, resolve machine- specific problems. Check the space of your hard disk. If you have enough space to cover the installation, something else is causing the problem. Clean your temp directory and delete its content. 

Third, resolve common windows installer issues. Fourth, resolve application- specific errors. These are MSI application specific errors. If it is till not resolved, try enhancing the logging to identify the problem, then modify the defined configuration. source

Problem 4: Insufficient Disk Space

The most likely cause of this is that the file being copied is too large for the file system to handle. File Allocation Table (FAT32) is a file system that can only handle up to  4GB in size. Files are stored in cluster on disk. the size of the clusters depends on the size of the disk. The problem that many encounter now is one of the limits of FAT32: file size. New Technology File System (NTFS) replaces the FAT32 and makes a couple of improvements over FAT- based file systems. If you need to copy file that exceeds 4GB, you need make sure that the file system on the hard disk you are copying to is NTFS. source



Problem 5: Computer Replacement

Here's a list of file that needs to be backed- up:



  • Application Setting. If you look between the AppData folders, you'll see directories for each and every application you're running. These settings can often be restored from a backup so you don't have to adjust everything again.
  • Bookmarks. You can simply backup the application settings folder and restore it. 
  • Desktop Email. Make sure that you have backed up the files in these applications. 
  • Documents. You should always backup all of your documents.
  • Music. You can include this folder, however it is optional.
  • Pictures/ Videos. These are also optional. 
  • Virtual Machines. You should create a backup of your virtual machines every now and then, especially if you're using them at work. source
