Nowadays the appropriate way\nto disable an init script is to remove the 'S' links without removing\nthe 'K' links, for example by running\n\n\tupdate-rc.d foo disable\n\nUnfortunately:\n\n 1. That is not as well known is it ought to be.  For example, section\n    4.6.3. \"Restricting access to some server services\"[1] of\n    debian-reference could be clarified to emphasize this method.\n\n 2. Many packages seem to provide ENABLE/DISABLE variables in\n    /etc/default/foo, providing a confusing red herring for this\n    task --- a second method which does not work nearly as well,\n    as you pointed out.\n\n 3. The tempting \"update-rc.d foo remove\" (which removes the 'K'\n    links, too) might _seem_ to work, except that the next time the\n    foo package is upgraded, the service is back again.\n\nOne possible way to move forward would be to write a patch to the\ndebian reference and any other pertinent documentation to address (1)\nand (3) and (once consensus that this is a good idea is reached) to\nfile bugs requesting removal of the ENABLE/DISABLE vars to address (2),\nblocking this bug by them.  When the last such variable is eliminated\nfrom the default conffiles in /etc/default, this bug could be closed.\n\nA complicating factor is that the sysadmin may already have customized\nsome ENABLE/DISABLE settings and a move like this should not override\ntheir settings.  So perhaps packages should stop advertising the\nENABLE/DISABLE vars in /etc/default/<package>, but continue to respect\nthem when set.\n\nSane?\n\nThanks,\nJonathan\n\n[1] http://www.debian.org/doc/manuals/debian-reference/ch04.en.html#_restricting_access_to_some_server_services\n\n\n\n-- \nTo UNSUBSCRIBE, email to debian-devel-REQUEST@lists.debian.org\nwith a subject of \"unsubscribe\".

I\n   don't know an efficient way to find out how many packages this would\n   make buggy.  But given that we have very strong reasons against the\n   old practice, we might want to use a 'should not' regardless.\n\n2. Do we need to include any text saying *why* the /etc/default practice\n   is a bad idea?  I couldn't come up with a succinct way to state it.\n   In general, I think we can err on the side of not including the text,\n   since we have policy bugs that document the reasons.\n\n3. The maintscript snippet I have added is not right because it will\n   disable the daemon every time the package is updated.  Unfortunately,\n   the postinst doesn't know whether this is a new installation, or an\n   upgrade.\n\n   An alternative is to require the package maintainer to set the\n   correct LSB headers and systemd unit file configuration values such\n   that the daemon is not autostarted (in the former case, setting the\n   daemon not to be started at any runlevel).  But I think this would\n   prevent the local system administrator from enabling the service with\n   a simple `update-rc.d package enable`, which is the whole point of\n   all this.\n\n   I looked at dh_installinit(8) and update-rc.d(8) and I couldn't get\n   them to generate a postinst that does what I want.  It seems you're\n   expected to use all three of these:\n\n       dh_systemd_enable --no-enable\n       dh_systemd_start --no-start\n       dh_installinit --no-start\n\n   but then after a reboot, a sysvinit system will start the daemon,\n   AFAICT.\n\n-- \nSean Whitton\n"

(This is a regression compared to the previous\napproach.)\n\nTo make this work correctly, I think we need a new update-rc.d\nmechanism which provides, in one go, the equivalent of\n  update-rc.d DAEMON defaults && update-rc.d DAEMON disable\n\nSomething like\n  update-rc.d DAEMON add-disabled\nmaybe.\n\n> > +An older practice, which should not be used, was to include a line\n> > +like ``DISABLED=yes`` in the package's ``/etc/default`` file.

But given that we have very strong reasons against the\n>    old practice, we might want to use a 'should not' regardless.\n\nOn sysvinit systems, using update-rc.d disable/defaults are rather\nmore awkward:\n\n * Enabling and disabling cannot, in practice, be conveniently made\n   without using the update-rc.d tool.\n\n * Enabling and disabling generates a tremendous amount of noise in\n   /etc (especially visible when using etckeeper).\n\n> 2.

However, I also think we need a system-wide policy mechanism to\nallow the sysadmin to say \"start things by default\" or \"don't start\nthings by default\". Similar to systemd's \"preset\" mechanism, and ideally\nusing that under systemd, but providing the same level of control for\nnon-systemd init systems.\n\n> > > +An older practice, which should not be used, was to include a line\n> > > +like ``DISABLED=yes`` in the package's ``/etc/default`` file.

They also make it difficult to\nprogrammatically configure services, such as by dropping in a\nconfiguration .d file from a configuration package.\n\n"

+
+In this lab, I learned about how to use tests in javascript and how to view my test coverage
+<!-- more -->
+
+## Testing in javascript with Jasmine
+With jasmine, tests are stored in *.spec.js files, and each "spec" is a way to give a test a name and designate it a purpose. Specs can be grouped in describe blocks that are often testing one function. Tests follow a syntax of passing in a function result into an `expect` function, which then tests it with the `toBe` function and if the results are the same the test passes.
+
+## Viewing test coverage with nyc
+With nyc you can view the test coverage of a jasmine test suite, and it will show you what percent of functions, and lines are uncovered, as well as which lines are not covered with a test.
+
+## Debugging javascript
+You can debug a javascript file with the `node inspect "filename.js"` command, and you can then inspect it from the command line or use an interactive debugger in a chrome based browser.
+
+## Objects in javascript
+Objects in javascript are similar to mutable hash tables, and you can see this as an object function is just the "key" to a function inside the object.
+
+## Json parsing
+In javascript you can parse a json file and parse it directly into an object. You can then perform any actions on this object. Assuming you are aware of what the object should contain you can then perform objects actually fitting of the object (like searching for a name in a json array of people).

+    Tags: cs2613, lab, javascript, methods, tests, classes, prototypes, arrays, recursion
+
+In this lab, I learned about classes, prototypes, arrays and how to use recursion in javascript
+<!-- more -->
+
+## Prototypes
+In javascript, there is a notion of a prototype, which is a way of making objects by calling the `Object.create()` function on a "prototype" of an object, which can be viewed as a form of constructor
+## Classes
+In reality, classes should be made by the new keyword instead of calling `Object.create()`. In "recent" times there has been an addition to javascript which allows the use of the class keyword and a constructor keyword, which lets you define an object in a very similar way to Java. It should be noted that both the new and the class/constructor syntax is just the same prototype based system that has been made more convenient to read.
+## Arrays
+Arrays in javascript are implemented as objects, which is similar to java, but due to the type casting nature of javascript can lead to some unintuitive behavior. We were tasked to create a function that takes a range and creates an array filled with numbers from the start of the range to the end. This can be achieved with a simple for loop.
+
+We were also tasked with creating function that sums the elements of a javascript array. This can also be done with a for loop, by looping over each element and adding it to a running total and returning the result. We were introduced to some higher order functions like reduce and forEach, which take functions as arguments and are similar to `foldl` in racket. We can use foreach as a way to skip the syntax of a normal for loop and simply operate once on each element of an array.
+## Recursion
+We were tasked with using recursion to recreate the `mult` and `add` methods from the first javascript lab, but with recursion. In my opinion it was much more readable than the sample racket solution, but there was an noticeable similarity in the syntax

+    Tags: cs2613, lab, python, pytest, exceptions, modules
+
+In this lab I learned about python, pytest, python exceptions and modules.
+<!-- more -->
+
+## Pytest
+Pytest is a python testing framework. It can show you code coverage with line counts. This is pretty similar to `nyc` from javascript. You run tests by just running `pytest` or `pytest -cov` for code coverage. Tests are defined by in a file having a function with an assert statement. Pytest will then scan your files for assert statements and run those functions to run tests. Testing in python is pretty simple, like with javascript. Racket testing is a little more abstract and confusing in my opinion.
+
+## Modules
+In python functions are exported by default, in contrast to javascript. You must guard your main method with the `if __name__ =='__main__'` text so it does not run when the module is imported. You can make tests to ensure you have documentation for your functions, by checking for the imports `__doc__` variable. 
+
+## Indentation
+In python, blocks are defined by indentation (also known as whitespace). This sets the scope for a given statement. It can be a little confusing to tell if an if statement is in a for loop or not, but linters help.
+
+## Exceptions
+Python can raise errors when things go wrong, for example diving by zero. You can catch these exceptions and handle them if you desire.
+
+## FizzBuzz missing case
+You can fix the missing case just by adding another if statement above the other if statement for the fizz case.
