+====Week 6====
+====C Prog====
+Reminder, don't wait until after break to write the weblog for the prior weeks information.  To the best of my memory, I believe we were going over using gd and feeling out how to maneuver the space we created to make various colors and shapes.  We went over how to fill in shapes with different colors, and create patterns and basic algebra or trig in loops to create images.  Array's will also be an important part of this I'm sure.  The project of the week is to create a circle out of overlapping squares.  Additionally we need to make a different colored boarder, that's not the same color as the circle, assuming the circle isn't every color available.  The most difficult part of this project, and not because it's hard, but because it's something we've buried deep down and tried to forget, is the trig side of plotting points to create shapes, and how to get each point.  Using our old friends of sin, cos, and tan, as well possibly radians or degrees and some other long lost formulas.  I think once you get the first shape though, it becomes much easier to replicate and modify them, just with some tweaking to get use to where you want each thing in the space created.  Overall this project seems pretty enjoyable once you get the concept and practice down.
+====UNIX====
+I think we worked on more scriptfun stuff in class.  A lot more practice using the $RANDOM feature, and echoing out the numbers instead of just fprintfing like how we're typically use to.  The terms are a bit different in script, aside from echo we also use read and fi to end the if loop.  We made a random number generator game that lets you know that you're too high, too low, or correct in your guesses.  The code allowed the user to know the number for the purpose of testing, but that's easily removed.  We can also set the number of guesses allowed before the program terminates.  A little more practice with breaks as well.  As for the project we're getting to learn a little bit of HTML for this adventure for web hosting coding.  We'll use these several web pages that we created to make an adventure of sorts out of it.  It's up to us what theme to use, if any, and how random we want the 9 or more levels to be through the adventure.  This will be one of the more interesting projects in terms of actually sharing it with others.  By that I mean we're actually encouraged to share our programs and try them out, otherwise the only person to get to enjoy them would be Matt.
+====Week 7====
+====C Prog====
+If I gcc a shell script for a third time, I might just flip a table.  Chmod, chmod, chmod, chmod, chmod.  Don't forget the u+x when necessary.  Completed the a week and a day early, really only a day early, but good ole push-backs make it all the better.  It was a fairly easy project in retrospect given most of the code, and examples.  The only real annoyance is that with larger squares, and only using a point every pi/72 there's no easy way to make the final point on the right not look awful if you alternate your colors.  There's just one box sitting on the rest, and the only way I can think to get rid of it is to either insert tiny rectangles to emulate 2 other squares overlapping with the appropriate colors, or add so many more points that they blend much nicer and aren't as visually boxy.  This past week in class was a grab bag of various things to review/learn depending how well you've paid attention, and get comfortable with before delving into the world of C++.  The next project is another mental math one, it feels faintly familiar to the multiply by 11 project we did before break.  The main wrench in the works that I think is in this one, is this idea of pointer functions, and all the things that go into that.  Let's just call it an interesting project.
+====UNIX====
+Same thing as prior, ingrain the different types of compilers so you don't lose any more code. that's simply not productive to our laziness.  In class we've messed with more scriptfun shellscripts, making pseudorandom number generators and setting parameters for user inputted guesses with how many guess allowed / indicators of how close the guesses were.  A lot more practice with loops and learning more about how to run commands outside of the usual text editors for ease of checking things/understanding.  The two projects coming up are the html web adventure which isn't too bad so far, and then a unix data recovery project.  The first puzzle box was a pain, the second one felt much easier aside from an extra secret space at the end of a file... This seems to have a similar feel, and will hopefully come more like the second puzzlebox than the first.  Seems like it'll be a lot more practice in decoding, and more to the point of how to manipulate the different bases of 2, 10, 8, etc.  It makes me curious how much time and effort is put into the really in dept data recovery, the stuff companies like Staples and Best Buy send out and charge hundreds of dollars for, if not more.
+====Week 8====
+====C Prog====
+This week we have begun learning the joys of programming in C++.  Realistically it's not that much different than C, and we're using all the same things we learned in the past and applying them accordingly.  There are an assortment of new file extensions to choose from, .cc being the one I'll likely be using, and a new compiler in g++.  There was a lot to learn in terms of public and private access, and various innuendos to go with them as such.  The project for this week was extended from last week, in part because all but 1 person was still fairly far off from completion.  Maybe two people.. one other was close.  The mental math aspect of the project isn't anything new, and something we've transitioned nicely into as a constant reminder.  However we sort of just dove into functions having never done a project with them before, with the added joy of pointers.  Functions are more confusing due to how much the setup changes, where you define and call can vary, and everything seems much longer.  I understand their importance, and the advantages they give to very long code with repeated actions, they're just currently unfamiliar territory still.  It's no longer the very simple linear a = this, b = that, do this, do that, all done!  Though we have been given extra time, and also this is something we have to learn to continue on, so we have no one to blame but ourselves if we aren't progressing.  The next project looks to be a bit "easier," in terms of how to conceptualize it and make it work.  Also having just gone over cryptography in discrete structures helps.
+====UNIX====
+This week in UNIX, we looked at an abundance of ways to treat our ASCII cat in ways PETA would not appreciate.  We learned different programs we could have running, how to kill them, how to freeze them, how to reanimate them (sometimes causing them to actually die, since they don't when frozen).  Though I think technically they were already dead and just weren't visually represented as such until you tried to unfreeze them.  We also worked on ways to grep things, like acquiring specific usernames and number of terminals open.  The project for the week is a bit reminiscent of the puzzle boxes of the past.  It's a data recovery exercise, which mostly involves our ability to utilize the manual and our knowledge to manipulate data.  I think it'll be another one of those projects if you don't get right away, you'll bang your head until you do get it, and then you might bang it one more time for not realizing how simple the answer was.  Class on Thursday was pretty much cancelled by NYSEG, so the entry's a bit shorter on relevant info for the week.
+====Week 9====
+====C Prog====
+We have continued on with C++ learnings, with tuesday's class mostly being a review of the workings of a variety of permissions between parents and children, namely being that children do not have access to their parents privates.  Past the review of rectangle.cc, with all of it's this ->, return, setting and getting of the public and private types, we now have digit.cc.  We left off after setting up how to increment our digit based on bit, decimal, value, etc. to have decrement left over for Joe.  However despite being in class past the scheduled time, we never really ended up writing much new code and more so just going into other ideas based around it.  As for the lab this week it's a bit more interesting in my opinion because we're dealing with very simple ciphers.  In this case, a caesar cipher to encode and decode with.  From hearing what we needed to do, it sounded extremely simple, though on closer investigation that is not so much the case.  It still feels easier than our last project though, so that's something.  I think since this has like a real world spy feel, despite it being extremely dumbed down and simplified, it makes it a bit more fun.
+====UNIX====
+In UNIX we went over some more commands you can use in vi, and some in nano, to make life a little easier when coding.  Most of Thursday's class was more of a review for people who had finished last weeks project, because some people had still been struggling with how to do it, or understanding what they did to do what they did.  It definitely felt like the type of project that you could pretty easily throw your keyboard and go to a bar after trying to think on it alone in the dark for a couple hours.  Luckily there's power in numbers.  Even if some of those numbers lead you astray with a bunch of simple arithmetic to figure out values and places you don't need.  This weeks project is calculating the week of the semester based on user input for the name of the semester, start and ending dates, list of days class does not meet and day to check for the semester week.  There's a lot of information at hand, but it doesn't seem conceptually all that awful, maybe that's because of what we had to deal with last week.  By contrast this seems fairly simple, and it's just a little bit of a headache to figure out how to set it all up to recall and read properly, but once you get into the flow it should be easy to finish out.
+====Week 10====
+====C Prog====
+Just one more week, and then there's a break.  You can do this.  And then there's two weeks, and the final experience and personal know how stuff.  You're screwed.  As for class this week, we worked more on digit.cc, learning more in the workings of c++ and how much more we have to write to it than c.  Matt did mention the possibility of the void digit :: decrement() being on our end of year experience thing, make a mental note of that.  Maybe even look into working on it ahead of time, you know, to make it that much easier.  The project continues to grow with all the various get and set base, sum, carry accessor functions, while decrementing and incrementing the stuff.  As for the projects, they continue to get more complex as expected.  Need to put more time into them , only 3 weeks of class left, slacking will quickly snowball downhill.  The last project was mostly confusing in figuring out how to use the !=EOF, getting information from cypher.key files and setting that up as a default if no cypher key was given from stdin, fun things of that nature.  I understood how the last project worked out, and could look at code to recognize what was happening, but writing it from scratch typically gave me a flight response.  I think working it out on paper first, like is typically asked of us in the project, helps a lot.  Must submit next time.
+====UNIX====
+This week in UNIX we continued to increase our knowledge of basic but useful command line terms for catting and grepping.  We even took at look at seding.  It was part review, and then moving forward, on things like finding words with no lower case vowels by typing cat words | grep '^[^aeiouy]*$'.  This goes from the start of the line to the end of the line, making sure that aeiouy are not any of the included, with the * being 0 or more of the previous (or not of).  Another good example was to find all the words with the start and end with a vowel, that are 2 or more words.  We did this by using cat words | grep '^[aeiouy]$.*[aeiouy]$'.  Again this looks for words that at the start(^) have a lower case vowel, are at least two letters(.*), and end($) with a lower case vowel.  The project we have this week is an extension from last weeks, working with the calendar and figuring out what semester it is based on the week given.  This I will begin working on shortly, days before it's due, as is customary of my people.  We trans procrastinatory people can't help it, and any nay sayers will be abruptly reminded to check their privileged on twitter as such.
+====Week 11====
+====C Prog====
+So this is it, this is what it all comes down to.  This week we finished off more in the bag of tricks, basically just trying to finalize things we've done and adding on a few other things for scripting/C++.  It seems like students and staff alike are ready for it to be over, so to be honest it's harder to pinpoint what we did each day.  The last project was a nice one to go on vacation to, and I finished beforehand to load up on bonus points which will hopefully alleviate some of the previous screw ups in terms of points.  My brain is mush and this final experience project things will probably be the downfall of it into an even more pureed form.  Overall it's been a good semester, I think we learned the majority of what we were meant to.  I dread to think of what I'll have to attempt to recall from the weeks prior the break...  Oh well it will all be over soon?
+====UNIX====
+Same thing as above, blah blah blah everything is almost over and very few people are operating on anything other than sheer forceful will.  I feel I've learned quite a bit over this course, and it's a much different setting than C.  It's less piece a, apply in project b, piece c, apply in piece d.  Not to say all of C was that way, there was a lot of go find stuff in the manual or google yourself moments, but UNIX seemed to have way more here's piece a, now do project theta.  It took a bit more collaboration and abstract thought to accomplish the goals.  Hopefully the final experience project will be just as thrilling, though I fear I'll miss the grade school html coding adventure.  I am curious as to if we could pluck students from another college in the same / similar programs and see how they've learned and applied their knowledge vs ours.  These next two weeks will probably fly by, aside from the few hours of bashing my head against the keyboard while trying to complete the final project.  Soon we'll be back to mindless self indulgences and not having to put on pants for hopefully days on end.
+====Week 12====
+====C Prog====
+So this week we were introduced to our End of Course Experience and FUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU
+====UNIX====
+UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUnnily enough I'll need to put a **lot** of time into it.  19 credit hours didn't seem so bad until now, when everything is being piled on.  It makes me wish we started in early August and finished finals the week before the Thanksgiving break.  I assume they keep summer the length it is to allow for summer classes and to reduce the amount of time students can forget things from fall to spring... but who knows with how these systems work, assuming there is a logical explanation.  If only we could be graded on everything before the break in UNIX... yea, that'd be good.  It's nice to know students aren't the only ones struggling to stay on topic and focus'd though.
