mock object "simulated objects that mimic the behaviour of real objects in controlled ways, most often as part of a software testing initiative"
assertions "Several modern programming languages include checked assertions – statements that are checked at runtime or sometimes statically. If an assertion evaluates to false at runtime, an assertion failure results, which typically causes execution to abort. This draws attention to the location at which the logical inconsistency is detected and can be preferable to the behaviour that would otherwise result. The use of assertions helps the programmer design, develop, and reason about a program."
.Net assertions in managed code (c#, vb, f#)
A mutable value is one that can be changed without creating an entirely new value. Immutable object "Strings and other concrete objects are typically expressed as immutable objects to improve readability and runtime efficiency in object-oriented programming. Immutable objects are also useful because they are inherently thread-safe."

Programming paradigm - "a way to classify programming languages based on their features. Languages can be classified into multiple paradigms"
list of Statically_typed_programming_languages
reflexive - can examine and modify its own structure and behavior. "Reflection is often used as part of software testing, such as for the runtime creation/instantiation of mock objects."
"In some object-oriented programming languages such as C# and Java, reflection can be used to bypass member accessibility rules. For C#-properties this can be achieved by writing directly onto the (usually invisible) backing field of a non-public property [c.f.] . It is also possible to find non-public methods of classes and types and manually invoke them. This works for project-internal files as well as external libraries such as .NET's assemblies and Java's archives."

"One of Flyvbjerg’s precepts is “Think slow, act fast.” If you plan well, that is, the execution will be swift. The phrase is a deliberate echo of “Thinking, Fast and Slow,” the title of a book by Daniel Kahneman, the psychologist who won a Nobel in economics. The two scholars are full of praise for each other; Kahneman cited Flyvbjerg in his book."

structural link between two peer classes
Add arrows at either end or both ends to show that the classes are aware (or unaware) of each other.
special type of association
one class might use an object of another class in the code of a method. If the object is not stored in any field, then this is modeled as a dependency relationship.
changes to the definition of class 2 may cause changes to class 1 (but not the other way around).
Class1 depends on Class2
e.g. The Person class might have a hasRead method with a Book parameter that returns true if the person has read the book
Special type of association “part of” e.g. class 2 is part of class 1
Association end gets the unfilled diamond (class 1 in this example)
Aggregate end has no diamond (class 1 in this example)
is a special type of Aggregation where parts are destroyed when the whole is destroyed
class 2 cannot stand by itself

in putty, must turn on x11 forwarding (can only do it from putty.exe without ip address argument)
[ in your putty shortcut, you must remove the ip address argument you are passing. if you don't remove argument, you don't get same configuration settings]
after connected, start gnome in putty window with "/etc/gdm/Xsession default"
Q: Can x11 be enabled in putty by reconfiguring the settings or only form the command line?
A: You can do it in the gui, but not if you are passing an ip address as an argument to putty
Q: Is there a port number for x11?
A: No. In Connection->SSH->X11, check "Enable X11 forwarding" and enter your windows ip in "X disiplay location".

settings for xming i used are "start no client" & "no access control" - don't know if required or works with other settings too

c++ notes
g++ compiler implementation stops reading chars at a space, so use cin.getline(szString,
iNumCharsToRead) to get strings with spaces.
-s = gcc flag for silent compile (only show errors, not compile command)
to make the package, just follow the procedure in his [Dr. Yoo's] slides. there is one problem though. for some of the compiles, you need to have
.;
before the path. so if you are making edu.gannon.MyPackage and you are going to put in on your c drive, the CLASSPATH environment variable must be
.;c:\edu\gannon\MyPackage;<path of library sub-directory created when you installed java>
and you must create the directory on the c drive before you compile.
when you go to run it, you have to remove the
.;
from the path, so CLASSPATH should be
c:\edu\gannon\MyPackage;<path library sub-directory created when you installed java>
remember that the dos boxes don't update the enviroment variables when you change them in windows 2000, so you have to close them and open them again.

The order in which this function returns the file names is dependent on the file system type. With the NTFS file system and CDFS file systems, the names are returned in alphabetical order. With FAT file systems, the names are returned in the order the files were written to the disk, which may or may not be in alphabetical order.
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/fs/by_handle_file_information_str.asp
Not all file systems can record creation and last access time, and not all file systems record them in the same manner. For example, on a Windows NT FAT file system, create time has a resolution of 10 milliseconds, write time has a resolution of 2 seconds, and access time has a resolution of 1 day (really, the access date). On the NTFS file system, access time has a resolution of 1 hour. For more information, see

No intellisense for Visual C++ 2010: when the CLR = Common Language Runtime Support is enabled, Intellisence will not work. This differs from 2008 where it did work and apparently Microsoft has no plans to add it to 2010.

https://www.arbourgroup.com/blog/2015/verification-vs-validation-whats-the-difference/
The distinction between the two terms is largely due to the role of specifications. Validation is the process of checking whether the specification captures the customer’s requirements, while verification is the process of checking that the software meets specifications.
Verification includes all the activities associated with the producing high quality software. It is a relatively objective process in that no subjective judgement should be needed in order to verify software.
In contrast, validation is an extremely subjective process. It involves making subjective assessments of how well the (proposed) system addresses a real-world need. Validation includes activities such as requirements modelling, prototyping and user evaluation

https://www.linkedin.com/pulse/difference-between-error-fault-defect-failure-ivan-luizio-magalh%C3%A3esSoftware testing has three main purposes:
Verification - The verification process confirms that the software meets its technical specifications. A specification is a description of a function in terms of a measurable output value given a specific input value under specific preconditions. A simple specification may be along the line of a SQL query retrieving data for a single account against the multi-month account-summary table must return these eight fields <list> ordered by month within 3 seconds of submission.
Validation - The validation process confirms that the software meets the business requirements. A simple example of a business requirement is after choosing a branch office name, information about the branch’s customer account managers will appear in a new window. The window will present manager identification and summary information about each manager’s customer base: <list of data elements>. Other requirements provide details on how the data will be summarized, formatted and displayed.
Defect Finding - A defect is a variance between the expected and actual result. The defect’s ultimate source may be traced to a fault introduced in the specification, design, or development (coding) phases.
