======Part 2====== =====Entries===== ====Entry 5: March 2, 2012==== Today using the lab46 net boot, I installed debian on 5 different machines. I am beginning my journey to create an orchistra of pc speakers using the beep command. All the names of the computers are of similar style as foxtrot. ====Entry 6: April 4, 2012==== Today I researched the different modifications to vim, from line numbers to syntax coloring. As I researched, I had found that there are several themes to choose instead of the default syntax coloring. Right now I'm using the desert theme. ====Entry 7: March Day, 2012==== This is a sample format for a dated entry. Please substitute the actual date for "Month Day, Year", and duplicate the level 4 heading to make additional entries. As an aid, feel free to use the following questions to help you generate content for your entries: * What action or concept of significance, as related to the course, did you experience on this date? * Why was this significant? * What concepts are you dealing with that may not make perfect sense? * What challenges are you facing with respect to the course? Remember that 4 is just the minimum number of entries. Feel free to have more. ====Entry 8: March Day, 2012==== This is a sample format for a dated entry.

By backspacing in terminal ===Experiment=== I will attempt to remove the probe in pcspkr disabling it from beeping anymore when I backspace in terminal ===Data=== I begin by logging into Foxtrot. From here I use the -r appendage to the modprobe command. thakes3@foxtrot:~$ sudo modprobe -r pcspkr password: thakes3@foxtrot:~$ from here I will try to backspace to see if the terminal will beep lab46:~$ ===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) - nope * What shortcomings might there be in your experiment? - when i reboot, it will revert back to normal * What shortcomings might there be in your data? - I don't know of any so far ===Conclusions=== Now the beep will not bother me, as it is long gone. ====Tripple Screening with X==== ===Question=== Is it possible to create multiple monitors without the need of an external graphics card in linux? ===Hypothesis=== By attempting to configure X to my needs, I should be able to make my computer be able to handle three heads at once. ===Experiment=== By editing my X11 configuration file ===Data=== I started off by running X -configure in root user mode with no GUI present. bravo:~$ cd /etc/X11/ bravo:~$ X -configure I then began looking for the xorg.conf file. lab46:~$ find / -name 'xorg.conf' 2> /dev/null /etc/X11/xorg.conf lab46:~$ I added a third entry for the monitor I am trying to use and assigned it to the second graphics card. ===Analysis=== Based on the data collected: * Was your hypothesis correct? - I would assume so, but I cannot get it to work. * Was your hypothesis not applicable? - It's not applicable in the sense that I would only need to edit that one file. There are other files linked that I do not have enough information about * Is there more going on than you originally thought? (shortcomings in hypothesis) - Yes there is * What shortcomings might there be in your experiment? - the X server isn't built for three screens on pci hardware * What shortcomings might there be in your data? - possibly I would need a third party application to get it to work ===Conclusions=== Multiscreening is hard! ====Retest 2==== Perform the following steps: ===State Experiment=== Whose existing experiment are you going to retest? Provide the URL, note the author, and restate their question. ===Resources=== Evaluate their resources and commentary. Answer the following questions: * Do you feel the given resources are adequate in providing sufficient background information? * Are there additional resources you've found that you can add to the resources list? * Does the original experimenter appear to have obtained a necessary fundamental understanding of the concepts leading up to their stated experiment? * If you find a deviation in opinion, state why you think this might exist. ===Hypothesis=== State their experiment's hypothesis. Answer the following questions: * Do you feel their hypothesis is adequate in capturing the essence of what they're trying to discover? * What improvements could you make to their hypothesis, if any? ===Experiment=== Follow the steps given to recreate the original experiment. Answer the following questions: * Are the instructions correct in successfully achieving the results? * Is there room for improvement in the experiment instructions/description? What suggestions would you make? * Would you make any alterations to the structure of the experiment to yield better results? What, and why? ===Data=== Publish the data you have gained from your performing of the experiment here. ===Analysis=== Answer the following: * Does the data seem in-line with the published data from the original author? * Can you explain any deviations? * How about any sources of error? * Is the stated hypothesis adequate? ===Conclusions=== Answer the following: * What conclusions can you make based on performing the experiment? * Do you feel the experiment was adequate in obtaining a further understanding of a concept? * Does the original author appear to have gotten some value out of performing the experiment? * Any suggestions or observations that could improve this particular process (in general, or specifically you, or specifically for the original author).
