File Locks

These are security measures placed on files in order to limit the access of them to one single user or program at a time.

sysprog Topics

User-Space

This is the memory that is dedicated or being occupied to the user of the computer.

Kernel Space

The kernel is what controls the physical components of the computer and the space is the memory that is occupied by the kernel.

File Access

File access is the means of the OS in how it deals with open, read, write, lseek and close.

File descriptors

File is an abstract way to show how a file is being accessed.

Buffer

The memory that is temporarily saved by the user to ensure memory for their resources.

System Call

A request from a program to the Kernel of the OS. Requests may include hardware services or creating and accessing new processes.

File Types and File Properties

Regular file: The normal files that the user commonly creates and edits. Also the files that are found using the 'ls -a' command with no other special characters.

Directory: A list of files in a file.

Symbolic Link: A representation of another file that gives a text based directory listing as to where the file is.

Named Pipe: Connect the output of one process to the input of another.

Socket: A file that lets two processes communicate.

Device File: The method of how hardware devices on the system are handled. They are also treated as a form of file called a device file.

Bit Sets & Bit Masks

Bit masks allow a set of bits to be either turned on or off using the AND operator.

User ID, Group ID

This is a permissions setting on an executable. It allows a user or set of users to temporarily have admin privileges while not normally having these privileges.

inodes and Data Blocks

AN inode itself stores all the information about a file except its name and data. A data block is a set of inodes placed together.

Directories

A directory is a virtual folder. A folder may contain more folders or data. This is the object oriented way in which files are virtually stored.

Links are what place the file system of a computer together. If you have a file inside of a folder then that folder links to that file. There are also symbolic links also known as shortcuts. They are files that reference another file that executes.

Also planning an install of Linux on a PS2. If all goes well and by some streak of luck I can ge t a hold of many PS2s then there could be an army… hmmmm…

Method

Success will be measured by the usableness (←– thats a real word) of the PS2 as a Linux OS. If it won't install and crashes and burns then it was a failure.

Measurement

Follow your method and obtain a measurement. Document the results here.

Analysis

Reflect upon your results of the measurement to ascertain your achievement of the particular course objective.

  • How did you do?
  • Room for improvement?
  • Could the measurement process be enhanced to be more effective?
  • Do you think this enhancement would be efficient to employ?
  • Could the course objective be altered to be more applicable? How would you alter it?

sysprog Objective

Objective

State the course objective; define what that objective entails.

Method

State the method you will use for measuring successful academic/intellectual achievement of this objective.

Measurement

Follow your method and obtain a measurement. Document the results here.

Analysis

Experiments

Linux, Windows takeover

Question

What is the question you'd like to pose for experimentation? What effect will installing a windows partition after installing a linux partition will have? I wonder this because when I did this same install a few years back i could not access the linux partition.

Resources

Collect information and resources (such as URLs of web resources), and comment on knowledge obtained that you think will provide useful background information to aid in performing the experiment. http://ultimateedition.info/ This is the open source version of linux that I used for the experiment. I prefer this version that is based on Ubuntu as it comes with lots of eye candy. And we all love eye candy :)

Hypothesis

Based on what you've read with respect to your original posed question, what do you think will be the result of your experiment (ie an educated guess based on the facts known). This is done before actually performing the experiment. I believe it will be the same as before. (but fingers crossed)

State your rationale.

Experiment

How are you going to test your hypothesis? What is the structure of your experiment? I began by backing up the contents of my hdd (usually a good way to start.) Then I'm just going ahead and doing both of the installs beginning with the linux install and continuing to a windows install.

Data

Perform your experiment, and collect/document the results here. Basically what is happening is the Windows install is covering up the linux partition and masking it. As to why it is doing this I am not sure but it is surely pissing me off. Hopefully more thorough research later will give a solution.

Analysis

Based on the data collected:

  • was your hypothesis correct? Yes
  • was your hypothesis not applicable? No
  • is there more going on than you originally thought? (shortcomings in hypothesis) There is more going on in the background but I am not exactly sure what it is.
  • what shortcomings might there be in your experiment? Maybe it only happens on this computer.
  • what shortcomings might there be in your data? Testing with more than one computer would give better results.

Conclusions

What can you ascertain based on the experiment performed and data collected? Document your findings here; make a statement as to any discoveries you've made. I can ascertain that Windows is greedy and wants to take over any installations on your system that are not also windows.

Laptop LED Lighting

Question

What is the question you'd like to pose for experimentation? What is wrong with the alienFX colors on my laptop? To clarify my laptop has built in LED lighting and recently it stopped working. It is frozen on one color setting (the one I had it set to before it stopped working) and will not budge from that. Also I can not disable the lights so they are always on.

Resources

Collect information and resources (such as URLs of web resources), and comment on knowledge obtained that you think will provide useful background information to aid in performing the experiment. The information I got from the Dell help page (as you can imagine) was not useful whatsoever. It basically told me to call their tech support and they'd send someone. as far as forums of people with the same problems it reads that removing the battery and hitting the power button to doa hard reset may fix the problem.

Hypothesis

Based on what you've read with respect to your original posed question, what do you think will be the result of your experiment (ie an educated guess based on the facts known). This is done before actually performing the experiment. I'm gonna have to agree with everyone else and believe that doing the hard reset will fix the LED lighting.

State your rationale. I believe this will work because it doesn't seem that there could be another problem. If it was a hardware problem then you would think that the lights wouldn't turn on at all.

Experiment

How are you going to test your hypothesis? What is the structure of your experiment? I'm going to simply do what everyone else was saying to do and take the battery out and then hold in the power button for a few seconds.

Data

Perform your experiment, and collect/document the results here. After doing this the lights flashed on reboot and turned back on but they were still the same color as they were set to before the experiment. After going in to the settings and trying to change them they still stayed on the same colors.

Analysis

Based on the data collected:

  • was your hypothesis correct? No
  • was your hypothesis not applicable? No
  • is there more going on than you originally thought? (shortcomings in hypothesis) There is certainly a lot more going on because if a hard reset will not work and the lights still turn on then I don't know what could possibly be causing this to happen.
  • what shortcomings might there be in your experiment? I don't believe there are shortcomings in exactly what I did but there could be shortcomings in that I didn't try enough to get the lights to work. In example maybe reinstalling the actual program that allows you to change the lights would do the trick.
  • what shortcomings might there be in your data? Once again I don't believe there are shortcomings in the data. I did the experiment and the lights did not change colors.

Conclusions

What can you ascertain based on the experiment performed and data collected? Document your findings here; make a statement as to any discoveries you've made. Even though the lights are turning on there must be some kind of hardware issue on hand. As to what extent I'm not sure is the problem, but it does piss me off that I'm going to have to call Dell support and deal with them.
