Off Topic / Need help w/ Java

« on: September 22, 2015, 02:24:06 PM »

Hey guys, I'm partially really stupid if you can't remember, and I need help with figuring out what exactly my documentation provided for a code lab is specifying for me to do.  I figured some of you have some knowledge in coding and computer science and all that and I might as well ask here while I'm scratching my head trying to figure it out.

We're forming a primitive array that will store objects while keeping track of a class-level boolean that determines whether or not nulls are allowed in the array, and there are four constructors to implement.

Code: [Select]

DynArray ( boolean allowNulls )
Creates a DynArray object that may allow or disallow its elements to be null values, depending on the value provided for the allowNulls parameter.  The internal array created by this constructor is a small power of two that is provided by the implementor.

I'm confused about what it means in the bold.  The class implements RandomAccess and Iterable.  Where am I getting a small power of two from?  Am I just putting in whatever small power of two I feel like?  The default constructor of DynArray() also says "the internal array is a small power of two determined by the implementation."

Off Topic / Need Java Help

Hey so I'm clinically handicapped and I'm trying to do this lab for my intro to object oriented programming class.  I figure a good majority of you are familiar with code including Java, so I came to you guys for advice because most if not all of my friends are clueless as well.

There are three .java files in this project.  ProvidedCode was given and is not modified in any way, shape, or form.  StudentCode is where we write our methods.  StudentTests is provided and unmodified like ProvidedCode and runs Junit tests.


ProvidedCode.java

myVal = inVal;

String expectedOutput = "matches Higher Value";
assertTrue(actualOutput.equals(expectedOutput));
}
{
ProvidedCode myObj = new ProvidedCode(4);
String actualOutput = StudentCode.getBetween(myObj,4);
String expectedOutput = "matches Parameter";
assertTrue(actualOutput.equals(expectedOutput));
}
}
}


For some reason when I run it (running StudentTests.java), I run into failures on the second test for both testInstanceBetween() and testParamBetween().

What am I doing wrong here?  I'm open to hear advice and learn.

Off Topic / The Great Gatsby (2013)

« on: May 10, 2013, 01:30:44 AM »

WARNING spoilers.
Proceed with caution unless you've read the book/seen the movie.





I just got back from seeing the Great Gatsby movie.

Honestly, I feel like it was really great in some unique ways, and yet it was slightly dumbed down from the novel.  The soundtrack, like the movie overall, was great and yet sometimes not fitting.  I was really open to the whole Jay-Z thing, just because why the forget not, but then flux pavilion and it's like... why.  Then they kept repeating the rhythm/main verse of that Lana Del Rey song and it gets annoying a bit.  My only main gripes with the novel include ((the fact that Daisy/Tom's child was only mentioned and didn't appear until the end and for only a brief moment (which is weird because the child's appearance is supposed to hit Gatsby mentally), and there were too many points in the movie where it had fade ins/outs of Tobey Maguire/Nick Carraway typing out the story on a typewriter to his psychologist (but I guess you don't have much else to fill in the gaps as with the novel...).  The movie also seemed too CGI at times.  Also Myrtle's breast isn't exposed and flapping but I'm only complaining cause my teacher kept bringing up that detail ("flapping") at least 200 times when we read it.)).

I don't imagine many others have seen it right now at 2:30 in the morning unless you saw it at midnight but feel free to discuss, please try to keep plot details in transparent text.

Off Topic / Glee re-uses Jonathan Coulton cover for episode without crediting him

« on: January 24, 2013, 10:30:46 PM »

Original article:  http://www.buddytv.com/articles/glee/glee-roundup-baby-got-back-sca-48991.aspx
^{thanks to Rob DenBleyker of C&H for bringing this up in my Facebook feed}

Baby Got Back - Jonathan Coulton vs. Baby Got Back - Glee Cast Version

I managed to load them at the exact same time and managed to sync them up so that they were playing the exact same notes at the exact same time at the exact same rate.  Let me tell you, it's very clear that the Glee developers have blatantly ripped from this, not just in the song style itself, but apparently even tidbits of Jonathan's cover are still present!

After listening, I think that @GLEEonFOX may have even used parts of my recording. Do I hear a duck quack? And of course they say 'Johnny C'

EDIT:  The "Johnny C" line is at 2:17 in the Glee video above.  And the original.

What do you guys think though?  I mean normally most people tend to just bash Glee for being an overrated show to begin with and for causing tweeny bopper girls to say stupid stuff like "why are these old 70s bands covering Glee songs?!?!"... but whatever.

another edit:  NPR also threw in some thought into this little thing as well

Off Topic / URGENT: need add'l help with Android flashing

« on: December 24, 2012, 04:10:53 PM »

long story short:  I have an AT&T Galaxy S2 (SGH-i777).  A few days ago they rolled out Android 4.0.4 for the Galaxy S2 and it's an absolute failure of an update, causing my phone as well as many others to simply "freeze" while the screen is off, requiring a hard restart to work again.  Normally this only happened maybe once a week with 4.0.3, which I was okay with, but now it's an hourly thing.

I have rooted my phone already.  I don't have any warranty to begin with because I bought the S2 refurbished.  My phone is now magically on Gingerbread 2.3.4 (this isn't even the version of Android they shipped this phone with, it came with GB 2.3.6).

I need help on what to do next.  I'm supposed to install some kind of kernal with ClockworkMod Recovery but I'm lost here.

EDIT:  nevermind.  I know what I'm doing (I hope).


NEW UPDATE:  successfully installed a gingerbread kernal with ClockworkMod Recovery.  can I just throw on an ICS ROM and flash that?

Games / THQ defaulting on $50 million with Wells Fargo

« on: November 11, 2012, 02:56:32 PM »

http://www.ripten.com/2012/11/10/thq-defaults-on-50-million-line-of-credit/

The document goes on to indicate that THQ is in negotiations to repair the credit line. Were it to disappear, the publisher’s cash flow would be severely impacted. Additionally, they don’t have the funds to repay the credit right now. No other lender is going to bail them out, either. Were this to happen, bankruptcy seems like the only reasonable outcome.

THQ is responsible for publishing many well received titles, including those from the Saints Row and Red Faction series, and also hold agreements with other franchises such as Games Workshop and Nickelodeon.  THQ going out would be a big hit for many fans of these series :(

Does anyone else find this game incredibly fun?  I enjoy the naming of your disease mostly for things like this, but I guess the game's fun too.

iOS version / Android version







Personally I find this to be a much more enjoyable "successor" (in design at least) to Pandemic/2.  The game is free, but can be unlocked for $1.06 which allows for fast forward speed, no advertisements and inserting bonus genes (personally I just think ads can burn your battery more).  Madagascar, Greenland, Iceland, etc. "invincible countries" are actually capable of being infected without preemptively shutting borders/seaports too, you are also given the choice of starting country, and there are MUCH more countries to infect..  It heats my Galaxy S2 up like a bitch though and definitely can chew on your battery life if you aren't proper with brightness/etc.

Games / Amazon's "Best Deals of July"

« on: July 02, 2012, 12:59:13 AM »

http://www.amazon.com/gp/feature.html/ref=tsm_1_tw_s_vg_m6cx0y?docId=1000812791

For the month of July they're doing great deals on PC games, making games like the new Max Payne 3 50% off at $30 and the new Spec Ops: The Line also at 50% off for $25.  Many of the games also can likely be registered on Steam if they cite requiring Steam in the system requirements.

This is probably the only Amazon email I've ever read too.

Basically, they apply an extra charge simply for using IE7.  I think this is the funniest thing I've seen to stop usage of IE7, lol.
