(Chapter written by Jacques Garrigue)
This chapter gives an overview of the new features in Objective Caml 3: labels, and polymorphic variants.
If you have a look at modules ending in Labels in the standard library, you will see that function types have annotations you did not have in the functions you defined yourself.
#ListLabels.map;; - : f:(’a -> ’b) -> ’a list -> ’b list = <fun> #StringLabels.sub;; - : string -> pos:int -> len:int -> string = <fun>
Such annotations of the form name: are called labels. They are meant to document the code, allow more checking, and give more flexibility to function application. You can give such names to arguments in your programs, by prefixing them with a tilde ~.
#let f ~x ~y = x - y;; val f : x:int -> y:int -> int = <fun> #let x = 3 and y = 2 in f ~x ~y;; - : int = 1
When you want to use distinct names for the variable and the label appearing in the type, you can use a naming label of the form ~name:. This also applies when the argument is not a variable.
#let f ~x:x1 ~y:y1 = x1 - y1;; val f : x:int -> y:int -> int = <fun> #f ~x:3 ~y:2;; - : int = 1
Labels obey the same rules as other identifiers in Caml, that is you cannot use a reserved keyword (like in or to) as label.
Formal parameters and arguments are matched according to their respective labels1, the absence of label being interpreted as the empty label. This allows commuting arguments in applications. One can also partially apply a function on any argument, creating a new function of the remaining parameters.
#let f ~x ~y = x - y;; val f : x:int -> y:int -> int = <fun> #f ~y:2 ~x:3;; - : int = 1 #ListLabels.fold_left;; - : f:(’a -> ’b -> ’a) -> init:’a -> ’b list -> ’a = <fun> #ListLabels.fold_left [1;2;3] ~init:0 ~f:(+);; - : int = 6 #ListLabels.fold_left ~init:0;; - : f:(int -> ’a -> int) -> ’a list -> int = <fun>
If in a function several arguments bear the same label (or no label), they will not commute among themselves, and order matters. But they can still commute with other arguments.
#let hline ~x:x1 ~x:x2 ~y = (x1, x2, y);; val hline : x:’a -> x:’b -> y:’c -> ’a * ’b * ’c = <fun> #hline ~x:3 ~y:2 ~x:5;; - : int * int * int = (3, 5, 2)
As an exception to the above parameter matching rules, if an application is total, labels may be omitted. In practice, most applications are total, so that labels can be omitted in applications.
#f 3 2;; - : int = 1 #ListLabels.map succ [1;2;3];; - : int list = [2; 3; 4]
But beware that functions like ListLabels.fold_left whose result type is a type variable will never be considered as totally applied.
#ListLabels.fold_left (+) 0 [1;2;3];; Error: This expression has type int -> int -> int but an expression was expected of type ’a list
When a function is passed as an argument to an higher-order function, labels must match in both types. Neither adding nor removing labels are allowed.
#let h g = g ~x:3 ~y:2;; val h : (x:int -> y:int -> ’a) -> ’a = <fun> #h f;; - : int = 1 #h (+);; Error: This expression has type int -> int -> int but an expression was expected of type x:int -> y:int -> ’a
Note that when you don’t need an argument, you can still use a wildcard pattern, but you must prefix it with the label.
#h (fun ~x:_ ~y -> y+1);; - : int = 3
An interesting feature of labeled arguments is that they can be made optional. For optional parameters, the question mark ? replaces the tilde ~ of non-optional ones, and the label is also prefixed by ? in the function type. Default values may be given for such optional parameters.
#let bump ?(step = 1) x = x + step;; val bump : ?step:int -> int -> int = <fun> #bump 2;; - : int = 3 #bump ~step:3 2;; - : int = 5
A function taking some optional arguments must also take at least one non-labeled argument. This is because the criterion for deciding whether an optional has been omitted is the application on a non-labeled argument appearing after this optional argument in the function type.
#let test ?(x = 0) ?(y = 0) () ?(z = 0) () = (x, y, z);; val test : ?x:int -> ?y:int -> unit -> ?z:int -> unit -> int * int * int = <fun> #test ();; - : ?z:int -> unit -> int * int * int = <fun> #test ~x:2 () ~z:3 ();; - : int * int * int = (2, 0, 3)
Optional parameters may also commute with non-optional or unlabelled ones, as long as they are applied simultaneously. By nature, optional arguments do not commute with unlabeled arguments applied independently.
#test ~y:2 ~x:3 () ();; - : int * int * int = (3, 2, 0) #test () () ~z:1 ~y:2 ~x:3;; - : int * int * int = (3, 2, 1) #(test () ()) ~z:1;; Error: This expression is not a function; it cannot be applied
Here (test () ()) is already (0,0,0) and cannot be further applied.
Optional arguments are actually implemented as option types. If you do not give a default value, you have access to their internal representation, type ’a option = None | Some of ’a. You can then provide different behaviors when an argument is present or not.
#let bump ?step x = match step with | None -> x * 2 | Some y -> x + y ;; val bump : ?step:int -> int -> int = <fun>
It may also be useful to relay an optional argument from a function call to another. This can be done by prefixing the applied argument with ?. This question mark disables the wrapping of optional argument in an option type.
#let test2 ?x ?y () = test ?x ?y () ();; val test2 : ?x:int -> ?y:int -> unit -> int * int * int = <fun> #test2 ?x:None;; - : ?y:int -> unit -> int * int * int = <fun>
While they provide an increased comfort for writing function applications, labels and optional arguments have the pitfall that they cannot be inferred as completely as the rest of the language.
You can see it in the following two examples.
#let h’ g = g ~y:2 ~x:3;; val h’ : (y:int -> x:int -> ’a) -> ’a = <fun> #h’ f;; Error: This expression has type x:int -> y:int -> int but an expression was expected of type y:int -> x:int -> ’a #let bump_it bump x = bump ~step:2 x;; val bump_it : (step:int -> ’a -> ’b) -> ’a -> ’b = <fun> #bump_it bump 1;; Error: This expression has type ?step:int -> int -> int but an expression was expected of type step:int -> ’a -> ’b
The first case is simple: g is passed ~y and then ~x, but f expects ~x and then ~y. This is correctly handled if we know the type of g to be x:int -> y:int -> int in advance, but otherwise this causes the above type clash. The simplest workaround is to apply formal parameters in a standard order.
The second example is more subtle: while we intended the argument bump to be of type ?step:int -> int -> int, it is inferred as step:int -> int -> ’a. These two types being incompatible (internally normal and optional arguments are different), a type error occurs when applying bump_it to the real bump.
We will not try here to explain in detail how type inference works. One must just understand that there is not enough information in the above program to deduce the correct type of g or bump. That is, there is no way to know whether an argument is optional or not, or which is the correct order, by looking only at how a function is applied. The strategy used by the compiler is to assume that there are no optional arguments, and that applications are done in the right order.
The right way to solve this problem for optional parameters is to add a type annotation to the argument bump.
#let bump_it (bump : ?step:int -> int -> int) x = bump ~step:2 x;; val bump_it : (?step:int -> int -> int) -> int -> int = <fun> #bump_it bump 1;; - : int = 3
In practive, such problems appear mostly when using objects whose methods have optional arguments, so that writing the type of object arguments is often a good idea.
Normally the compiler generates a type error if you attempt to pass to a function a parameter whose type is different from the expected one. However, in the specific case where the expected type is a non-labeled function type, and the argument is a function expecting optional parameters, the compiler will attempt to transform the argument to have it match the expected type, by passing None for all optional parameters.
#let twice f (x : int) = f(f x);; val twice : (int -> int) -> int -> int = <fun> #twice bump 2;; - : int = 8
This transformation is coherent with the intended semantics, including side-effects. That is, if the application of optional parameters shall produce side-effects, these are delayed until the received function is really applied to an argument.
Like for names, choosing labels for functions is not an easy task. A good labeling is a labeling which
We explain here the rules we applied when labeling Objective Caml libraries.
To speak in an “object-oriented” way, one can consider that each function has a main argument, its object, and other arguments related with its action, the parameters. To permit the combination of functions through functionals in commuting label mode, the object will not be labeled. Its role is clear by the function itself. The parameters are labeled with names reminding either of their nature or role. Best labels combine in their meaning nature and role. When this is not possible the role is to prefer, since the nature will often be given by the type itself. Obscure abbreviations should be avoided.
ListLabels.map : f:(’a -> ’b) -> ’a list -> ’b list UnixLabels.write : file_descr -> buf:string -> pos:int -> len:int -> unit
When there are several objects of same nature and role, they are all left unlabeled.
ListLabels.iter2 : f:(’a -> ’b -> ’c) -> ’a list -> ’b list -> unit
When there is no preferable object, all arguments are labeled.
StringLabels.blit : src:string -> src_pos:int -> dst:string -> dst_pos:int -> len:int -> unit
However, when there is only one argument, it is often left unlabeled.
StringLabels.create : int -> string
This principle also applies to functions of several arguments whose return type is a type variable, as long as the role of each argument is not ambiguous. Labeling such functions may lead to awkward error messages when one attempts to omit labels in an application, as we have seen with ListLabels.fold_left.
Here are some of the label names you will find throughout the libraries.
| Label | Meaning |
| f: | a function to be applied |
| pos: | a position in a string or array |
| len: | a length |
| buf: | a string used as buffer |
| src: | the source of an operation |
| dst: | the destination of an operation |
| init: | the initial value for an iterator |
| cmp: | a comparison function, e.g. Pervasives.compare |
| mode: | an operation mode or a flag list |
All these are only suggestions, but one shall keep in mind that the choice of labels is essential for readability. Bizarre choices will make the program harder to maintain.
In the ideal, the right function name with right labels shall be enough to understand the function’s meaning. Since one can get this information with OCamlBrowser or the ocaml toplevel, the documentation is only used when a more detailed specification is needed.
Variants as presented in section 1.4 are a powerful tool to build data structures and algorithms. However they sometimes lack flexibility when used in modular programming. This is due to the fact every constructor reserves a name to be used with a unique type. One cannot use the same name in another type, or consider a value of some type to belong to some other type with more constructors.
With polymorphic variants, this original assumption is removed. That is, a variant tag does not belong to any type in particular, the type system will just check that it is an admissible value according to its use. You need not define a type before using a variant tag. A variant type will be inferred independently for each of its uses.
In programs, polymorphic variants work like usual ones. You just have to prefix their names with a backquote character ‘.
#[‘On; ‘Off];; - : [> ‘Off | ‘On ] list = [‘On; ‘Off] #‘Number 1;; - : [> ‘Number of int ] = ‘Number 1 #let f = function ‘On -> 1 | ‘Off -> 0 | ‘Number n -> n;; val f : [< ‘Number of int | ‘Off | ‘On ] -> int = <fun> #List.map f [‘On; ‘Off];; - : int list = [1; 0]
[>‘Off|‘On] list means that to match this list, you should at least be able to match ‘Off and ‘On, without argument. [<‘On|‘Off|‘Number of int] means that f may be applied to ‘Off, ‘On (both without argument), or ‘Number n where n is an integer. The > and < inside the variant type shows that they may still be refined, either by defining more tags or allowing less. As such they contain an implicit type variable. Both variant types appearing only once in the type, the implicit type variables they constrain are not shown.
The above variant types were polymorphic, allowing further refinement. When writing type annotations, one will most often describe fixed variant types, that is types that can be no longer refined. This is also the case for type abbreviations. Such types do not contain < or >, but just an enumeration of the tags and their associated types, just like in a normal datatype definition.
#type ’a vlist = [‘Nil | ‘Cons of ’a * ’a vlist];; type ’a vlist = [ ‘Cons of ’a * ’a vlist | ‘Nil ] #let rec map f : ’a vlist -> ’b vlist = function | ‘Nil -> ‘Nil | ‘Cons(a, l) -> ‘Cons(f a, map f l) ;; val map : (’a -> ’b) -> ’a vlist -> ’b vlist = <fun>
Type-checking polymorphic variants is a subtle thing, and some expressions may result in more complex type information.
#let f = function ‘A -> ‘C | ‘B -> ‘D | x -> x;; val f : ([> ‘A | ‘B | ‘C | ‘D ] as ’a) -> ’a = <fun> #f ‘E;; - : [> ‘A | ‘B | ‘C | ‘D | ‘E ] = ‘E
Here we are seeing two phenomena. First, since this matching is open (the last case catches any tag), we obtain the type [> ‘A | ‘B] rather than [< ‘A | ‘B] in a closed matching. Then, since x is returned as is, input and return types are identical. The notation as ’a denotes such type sharing. If we apply f to yet another tag ‘E, it gets added to the list.
#let f1 = function ‘A x -> x = 1 | ‘B -> true | ‘C -> false let f2 = function ‘A x -> x = "a" | ‘B -> true ;; val f1 : [< ‘A of int | ‘B | ‘C ] -> bool = <fun> val f2 : [< ‘A of string | ‘B ] -> bool = <fun> #let f x = f1 x && f2 x;; val f : [< ‘A of string & int | ‘B ] -> bool = <fun>
Here f1 and f2 both accept the variant tags ‘A and ‘B, but the argument of ‘A is int for f1 and string for f2. In f’s type ‘C, only accepted by f1, disappears, but both argument types appear for ‘A as int & string. This means that if we pass the variant tag ‘A to f, its argument should be both int and string. Since there is no such value, f cannot be applied to ‘A, and ‘B is the only accepted input.
Even if a value has a fixed variant type, one can still give it a larger type through coercions. Coercions are normally written with both the source type and the destination type, but in simple cases the source type may be omitted.
#type ’a wlist = [‘Nil | ‘Cons of ’a * ’a wlist | ‘Snoc of ’a wlist * ’a];; type ’a wlist = [ ‘Cons of ’a * ’a wlist | ‘Nil | ‘Snoc of ’a wlist * ’a ] #let wlist_of_vlist l = (l : ’a vlist :> ’a wlist);; val wlist_of_vlist : ’a vlist -> ’a wlist = <fun> #let open_vlist l = (l : ’a vlist :> [> ’a vlist]);; val open_vlist : ’a vlist -> [> ’a vlist ] = <fun> #fun x -> (x :> [‘A|‘B|‘C]);; - : [< ‘A | ‘B | ‘C ] -> [ ‘A | ‘B | ‘C ] = <fun>
You may also selectively coerce values through pattern matching.
#let split_cases = function | ‘Nil | ‘Cons _ as x -> ‘A x | ‘Snoc _ as x -> ‘B x ;; val split_cases : [< ‘Cons of ’a | ‘Nil | ‘Snoc of ’b ] -> [> ‘A of [> ‘Cons of ’a | ‘Nil ] | ‘B of [> ‘Snoc of ’b ] ] = <fun>
When an or-pattern composed of variant tags is wrapped inside an alias-pattern, the alias is given a type containing only the tags enumerated in the or-pattern. This allows for many useful idioms, like incremental definition of functions.
#let num x = ‘Num x let eval1 eval (‘Num x) = x let rec eval x = eval1 eval x ;; val num : ’a -> [> ‘Num of ’a ] = <fun> val eval1 : ’a -> [< ‘Num of ’b ] -> ’b = <fun> val eval : [< ‘Num of ’a ] -> ’a = <fun> #let plus x y = ‘Plus(x,y) let eval2 eval = function | ‘Plus(x,y) -> eval x + eval y | ‘Num _ as x -> eval1 eval x let rec eval x = eval2 eval x ;; val plus : ’a -> ’b -> [> ‘Plus of ’a * ’b ] = <fun> val eval2 : (’a -> int) -> [< ‘Num of int | ‘Plus of ’a * ’a ] -> int = <fun> val eval : ([< ‘Num of int | ‘Plus of ’a * ’a ] as ’a) -> int = <fun>
To make this even more comfortable, you may use type definitions as abbreviations for or-patterns. That is, if you have defined type myvariant = [‘Tag1 int | ‘Tag2 bool], then the pattern #myvariant is equivalent to writing (‘Tag1(_ : int) | ‘Tag2(_ : bool)).
Such abbreviations may be used alone,
#let f = function | #myvariant -> "myvariant" | ‘Tag3 -> "Tag3";; val f : [< ‘Tag1 of int | ‘Tag2 of bool | ‘Tag3 ] -> string = <fun>
or combined with with aliases.
#let g1 = function ‘Tag1 _ -> "Tag1" | ‘Tag2 _ -> "Tag2";; val g1 : [< ‘Tag1 of ’a | ‘Tag2 of ’b ] -> string = <fun> #let g = function | #myvariant as x -> g1 x | ‘Tag3 -> "Tag3";; val g : [< ‘Tag1 of int | ‘Tag2 of bool | ‘Tag3 ] -> string = <fun>
After seeing the power of polymorphic variants, one may wonder why they were added to core language variants, rather than replacing them.
The answer is twofold. One first aspect is that while being pretty efficient, the lack of static type information allows for less optimizations, and makes polymorphic variants slightly heavier than core language ones. However noticeable differences would only appear on huge data structures.
More important is the fact that polymorphic variants, while being type-safe, result in a weaker type discipline. That is, core language variants do actually much more than ensuring type-safety, they also check that you use only declared constructors, that all constructors present in a data-structure are compatible, and they enforce typing constraints to their parameters.
For this reason, you must be more careful about making types explicit when you use polymorphic variants. When you write a library, this is easy since you can describe exact types in interfaces, but for simple programs you are probably better off with core language variants.
Beware also that some idioms make trivial errors very hard to find. For instance, the following code is probably wrong but the compiler has no way to see it.
#type abc = [‘A | ‘B | ‘C] ;; type abc = [ ‘A | ‘B | ‘C ] #let f = function | ‘As -> "A" | #abc -> "other" ;; val f : [< ‘A | ‘As | ‘B | ‘C ] -> string = <fun> #let f : abc -> string = f ;; val f : abc -> string = <fun>
You can avoid such risks by annotating the definition itself.
#let f : abc -> string = function | ‘As -> "A" | #abc -> "other" ;; Warning U: this match case is unused. val f : abc -> string = <fun>

The project-navgiator has 3 sections: GALLERY, LOCAL PROJECTS, and ICLOUD PUBLIC. The gallery contains some examples to play around with, in "local projects" you can put your own projects with editting capability, and the icloud-part contains cloud-stored databases. The gallery and cloud sections are immutable, but can be dragged and dropped or copy-and-pasted to your "local projects"-section, after which they can be editted for content and appearance.
You can view and edit your own structures by importing them. The most common formats for structures are CIF-files and PDB-files. The easiest way of importing these types of files is to drag them from the Finder and then drop them in the project-navigator in the "local projects"-section. Alternatively, you can use the menu options "File" and then "Import".

I have been politically active and engaged since at least 2000, when I was just out of college and my roommate and I volunteered to assist former Sen. Bill Bradley’s campaign for President. We didn’t know what we were doing and probably weren’t all that helpful, but we wanted to be involved. In 2002 and 2004, I worked on campaigns for candidates for State Representative and District Attorney. I was a candidate for public office myself in 2008, when I won the Democratic nomination for the Jefferson County Board of County Commissioners (District 2). To the best of my recollection, I have donated money to the following candidates/organizations: Jeff Bridges for State Representative Mike Weissman for State Representative Jefferson County Democratic Party George Stern for Jefferson County Clerk Brittany Pettersen for State Senate David Ortiz for State Representative Andy Kerr for Jefferson County Commissioner
I have been active in my community in a variety of roles for more than 20 years. In the interest of sanity, I reduced much of my community engagement activities by the time my children were all old enough to be in school; for the purposes of this application I went back a few more years in listing organizations/associations. - Volunteer Basketball Coach Coached 2-3 different teams (boys and girls) each Winter; approximately 20 hours per week from November - March. (Just Play Sports): 2016 - PRESENT (Gold Crown Youth Sports): 2017 - PRESENT (Susan Duncan YMCA): 2012 - 2018 - Member, Parent Teacher Association Prospect Valley Elementary School (2011 - PRESENT) Manning Middle School (2018 - PRESENT) - Member, Board of Directors Second Wind Fund (youth suicide prevention): 2010 -- 2012 - Member, Board of Directors Denver SCORES (youth soccer and literacy): 2005 -- 2007 - Executive Board Member Jefferson County Council PTA: 2005 -- 2008 - Member, Society of Professional Journalists: 2006 -- 2018 - Member, Colorado Author’s League: 2008 -- 2018 - Member, Rotary Club: 2003 -- 2004
I am a fourth-generation Coloradan, a husband, a son, a brother, and a father of three children; as such, I view advocacy and contributing to the community to be a moral obligation as much as a personal choice. I have taken a particularly active role in issues regarding education, youth development, and after school activities (as evidenced by my leadership roles with the PTA, Second Wind Fund, and Denver SCORES).
Fair and equal representation is at the very heart of our political system. This is a principle that I take very seriously. I would be proud to be part of a commission that seeks to ensure that all Coloradans are equitably represented by its elected officials.
I am a Democrat who generally supports Democratic causes and issues. I don’t pretend not to have partisan leanings, but I believe that transparency is important if you hope to reach an impartial decision on any issue. Consensus comes from understanding and accepting different viewpoints, beginning with an honest discussion and a common goal of fairness. In terms of fairness and impartiality, I will always approach any discussion with an unshakable belief in facts -- from demographics and population numbers to geographic boundaries and landmarks. Factual information cannot be changed in order to support a different opinion.  It was always important to me to ensure the accuracy of my reporting and writing regardless of any particular perspective. I would do the same thing as a member of this commission.
During my career as a journalist, I learned that there are always multiple competing sides to any story -- but there are rarely competing sets of facts. Every decision or perspective should start from a foundation of objectively-true information. This approach has always served me well; if it can help me tackle a problem with strong-minded individuals on the Jefferson County Council PTA, it should be equally effective on the commission. While I would endeavor to ensure an educated and engaging discussion on the commission, I would be a strong voice for keeping the group focused on the ultimate goal of meeting deadlines for redistricting. The importance of immovable deadlines was drilled into me throughout my career; if I missed my deadline for publication or going on-air, it would cause a ripple effect for everyone else in the organization.

I realized that the JIRA voting mechanism provides site admins with the model needed to setup basic polls. All that was needed to finish the job was the interface. This portlet provides said interface and it's expected that this portlet will be of use in all JIRAs for a myriad of lateral thinking reasons.
Version 1.1 was released on 13th of May 2007. It (very quickly) added the feature to be able to dilute votes so that a user only gets 1 vote to share around and not one vote per issue.
Version 1.0 was released on 13th of May 2007.
Install the plugin by downloading the plugin jar, place it in your $JIRA/WEB-INF/lib/
and giving your JIRA a restart.
Once it's installed you can add it to your dashboard by selecting the Poll
portlet. Please follow the instructions from Atlassian for configuring your personal dashboard or the default dashboard.
The source is available for perusing by downloading the source zip and unpacking.
The first of three configurations is a comma-separated list of issue keys who will form the elements of the poll. If you just specify one issue key then its subtasks will be used.
The second configuration is the title for the poll. If you have specified just the one issue key then this is optional - the summary of the parent issue will be used if the title isn't specified.
The third and last configuration is whether to consider users as having many votes or just one vote. If they have just one vote (the default from 1.1 onwards) then their vote is shared between the issues they vote on. So if a user votes for two issues, each issue gets half a point.
The current plan is to add the following ideas:
Please mail these to me at henri-at-sourcelabs.com, or add them as comments to the JIRA plugin page.
There are two modes for the portlet. Logged in users see the following (also at the top of this page):
The information icon takes the user to the page for that issue, the thumb shows whether the user has voted for this issue and the pencil icon is used by the user to vote for an issue or remove their vote.
The difference for anonymous users is that they don't get access to a few of the icons:


Final Group Project
For the final project, you will work in groups of three or four to explore a
dataset with about 1000 to 4000
data points and turn your findings into a public history project, hosted
on your own project websites.
These datasets include, for example,
Cigarette advertisements
,
Opioid prescription data
,
Experience reports from people who take drugs
, or
radio show
transcripts.
Each project website needs to include:
- A narrative of about 2000 words that describes your research and
findings
- At least five visualizations that explore clearly defined questions
- An “About” page that describes the sources, processing, and presentation
that went into the project as well as your explanations for choices that
you make. The “About” page should also include short bios of the team
members and outline who work on what aspect of the project.
- An annotated bibliography of the literature and projects consulted
- A data critique that explains what information is included in your dataset
and what questions it can and cannot answer.
Sample Projects
For inspiration, have a look at these student projects:
Datasets
Here are datasets that you could consider working with:
-
Reddit Corpora: This is a great site
that gives you access to Reddit submissions in a very flexible way.
For example, you could get comments from
r/Drugs. Or you could get
a sample of comments mentioning Fentanyl from 2015 through 2020 and compare
them. Or you could get samples from different areas (r/Kentucky vs.
r/Boston) and see what patterns you can identify.
Mode of analysis: Primarily text, possibly geographic
-
Erowid: We have already seen
Visualizing Erowid. However,
the rich user reports aggregated by
Text Mining Altered States of Consciousness can yield many more insights.
Mode of analysis: Text
-
DEA Opioid Prescription Data
Multiple options. e.g. map out where drugs are distributed by pharmacies
in a county, potentially compare prescription rates to number of inhabitants
in a town. (In essence, a version of
this map. Geocoded pharmacy list available
here.
Mode of analysis: Mapping
-
Cigarette
Advertisments: This website collects thousands of cigarette
advertisements organized by themes. Could be used for an online exhibit
of a particular theme but also to generate, for example,
"average" advertisements by decade.
Mode of analysis: Images, online exhibits.

2 Chronicles 27:3
He built the high gate of the house of the LORD, and on the wall of Ophel he built much.


Will is the bearer of the knife. Now, accompanied by angels, his task is to deliver that powerful, dangerous weapon to Lord Asriel - by the command of his dying father.
But how can he go looking for Lord Asriel when Lyra is gone? Only with her help can he fathom the myriad plots and intrigues that beset him.
The two great powers of the many worlds are lining up for war, and Will must find Lyra, for together they are on their way to battle, an inevitable journey that will even take them to the world of the dead...

My favorite hobby of all is watching movies. Although it is not a physically productive activity, I enjoy doing it.
My most favorite type of movies are movies related to aircrafts and action movies. You might think that I dream of being a soldier but i'm not. I just enjoy watching it for no reason at all.
I also like movies about love stories. Not Love Stories like in the pocket books or wattpad but Love Stories like in real life. Stories that really happen in the real world. I'm not being corny, but it's just that while watching a movie about love, you can feel it too.
But I will not forget movies about God. It's important for me because Jesus sacrificed a lot for us.


How Nick DeLeon, Greg Vanney & Seattle Fans Could Each Make MLS Cup History
by Ian QuillenThere’s more than a little familiarity surrounding Sunday afternoon’s 2019 MLS Cup final, the third contested between the Seattle Sounders and Toronto FC, teams that just might be the MLS’ version of the prolific 1970s Pittsburgh Steelers and Dallas Cowboys squads that helped popularize the NFL.At the same time, it’s not exactly something the league has seen before.
While D.C. United and the LA Galaxy traded blows during MLS’ very early days, neither ever captivated its city as Seattle and Toronto do for theirs now. And whoever wins this rubber-match of a final after they spilt their 2016 and 2017 title games could be laying the groundwork to be considered the next MLS dynasty after the Galaxy’s reign ended following their fifth MLS Cup in 2014.
More concretely, there’s also quite a bit of individual and team history that is on the line Sunday, even if the final fixture feels like we’ve been here before
Nick DeLeon, The ‘Big Shot Bob’ Of MLS?
In his first season with Toronto, fullback Nick DeLeon has rediscovered the offensive promise he hasn’t showed since his 2012 rookie campaign with D.C. United. And if he scores Sunday in his first postseason with The Reds, he would seal his place as one of MLS’ greatest clutch playoff performers, with a penchant for scoring in huge moments much the way NBA forward Robert Horry did during his playoff career.
Simlar to Horry, a regular season role-player who earned the nickname “Big Shot Bob” for hitting some huge postseason shots, DeLeon has scored some incredible goals among his six playoff tallies. (Unlike Horry, who has an incredible seven NBA championships, DeLeon has never won MLS Cup, though he does have a U.S. Open Cup to his name.
DeLeon’s most memorable playoff strike may still be his first, which decided an epic 2012 Eastern Conference semifinal tie between D.C. United and the New York Red Bulls. His most recent, the 2019 Eastern Conference decider from distance against Atlanta United shown in the video above, was nearly as stunning. And his cracking, extra-time equalizer in the 2018 knock out round for D.C. against Columbus shown below was only overshadowed because D.C. eventually succumbed on penalties.
Further, DeLeon’s previous two goals this postseason have come off the bench, making him the seventh player in MLS history to score twice in the same postseason as a sub. If he scores off the bench as third time, he would be the first ever to do so.
Even if he scores as a starter Sunday, DeLeon would be the first MLS player ever to reach seven postseason goals before his 20th regular season tally. He’s already tied for second-highest among those with fewer than 30 regular season goals:
Top MLS playoff scorers w/fewer than 30 regular season goals
(Career regular season goals in parentheses)
- Nicolas Lodeiro: 7 (26)
- Raul Ruidiaz: 6 (21)
- Nick DeLeon: 6 (19)
- Tony Sanneh: 6 (16)
- Jordan Morris: 5 (25)
- Ezra Hendrickson: 5 (23)
- Greg Vanney: 5 (22)
- Adolfo Valencia: 5 (21)
- Carlos Hermosillo: 5 (14)
- Miklos Molnar: 5 (12)
Greg Vanney’s Sneaky Longevity
In terms of age, Toronto FC coach Greg Vanney is somewhere near the mean among the current cohort of MLS managers. But if he can win a second MLS Cup, he’ll join a club related to MLS coaching longevity that has exactly two members. Himself, and the league’s only five-time MLS Cup winning coach, Bruce Arena.
Vanney and Arena would be the only two coaches in league history to win an MLS Cup later than five years into their tenures with a given club. Vanney was hired midway through the 2014 campaign and thus is technically in his sixth season with The Reds. Arena was in his seventh season with the Galaxy when they won their third MLS Cup under his guidance in 2014.
The vast majority of MLS Cups – 16 of 23 in fact – have been won by coaches no more than three years into their club tenures at the time. Only two coaches – Arena twice in 2012 and 2014, and Peter Vermes in the year in between – have won MLS Cup as deep as their fifth season with a team.

- 2016: Brian Schmetzer (SEA, 1)
- 2017: Greg Vanney (TOR, 4)
- 2018: Tata Martino (ATL, 2)
How Many Seats Acutally Are There?
The Seattle Sounders have already announced Sunday’s noontime local kickoff will be a sell-out, with every seat CenturyLink Field open just as they are for the NFL’s Seattle Seahawks. Now the question is whether they can find enough extra seats to surpass last year’s MLS Cup attendance record set by Atlanta United.
Some 73,019 fans watched Atlanta defeat the Portland Timbers 2-0 to win their first title in club history at Mercedes-Benz Stadium. That’s more than 1,000 fans more than the listed capacity of The Link in Seattle. But it’s also more than 2,000 fans more than the listed capacity of The Benz in Atlanta. In other words, there is usually a little wiggle room to these totals, so the record would seem in play.
At worst, the match is a sure bet to be the second-most attended MLS Cup in league history.
Highest Attended MLS Cup Finals
- 73,019 – 12/8/2018, Mercedes-Benz Stadium, Atlanta
- 61,316 –10/20/2002, Gillette Stadium, Foxborough, Mass.
- 57,431 – 10/26/1997, RFK Stadium, Washington

oltpforever, oltpforever2 − Execute oltprun until canceled
oltpforever [-H] [-g] [-a] [-k key] [-R file] [-K n] [-W] [komment text ...]
oltpforever2
Execute 1h long runs of the oltp workload until canceled.
-H
Print short help.
-k key
Set the key that will be used when storing results in the repository database. The default is the same as the project name.
-g
Show graphs during the runs using gnuplot’s output to X-Windows. This requires a properly set DISPLAY environment variable.
-R file
In stead of using the normal run.rwl file count in the oltp directory, use the file named. The primary use of this is for experiments that require modifications to run.rwl.
-a
If your orders and order_items tables are partitioned, you can use the -a option to make sure an empty set of partitions are created at the start of the run. Only use this if the automatic allocation via interval partitions appears to cause trouble
-W
-K n
See COMPLETION at oltpcore(2rwl).
If your goal is to see progression over long time, you can use the oltpforever command to do so. It does little more than repeatedly doing oltprun making 3590s long runs. The process count for these runs is found in the parameter file which means you can change it without interrupting the oltpforever run. To stop the run after the next completion, remove the file named after your project with a .run suffix. Alternatively, simply hit ctrl-c, which however will terminate the last run prematurely without cleanup and without executing oltpplot. You can provide additional text for your generated html and graphic files by adding extra arguments to the oltprun command.
Note that there will be a period between the runs where your database under test has no workload. If you want a continuous workload, you can execute oltpforever2 (that does not take any options) within the first Â½ hour of starting oltpforever; simply start it in a new session. The latter will then execute the same workload continuously until stopped or canceled using ctrl-c) but shifted Â½ hour from the former to ensure a continuously loaded database. If using olptforever2 you should adjust the number of processes accordingly taking the double load from the two executions into account.

Authorities identify bizarre new trend after Qld schoolies week
by Monique StClairWeek one of schoolies has wrapped up, with authorities reporting less arrests and hospitalisations than previous years, along with a bizarre new trend.
The Safer Schoolies response has been working hard all week, to ensure all party-goers were kept safe and had a great time in Surfers Paradise.
This morning, they’re proud to announce it’s been a hugely successful week once again, crediting smaller crowds and better education for the good statistics.
Just over 15,500 school leavers descended on the Glitter Strip this past week, down approximately 27 percent on last year’s figures.
Chairman of Safer Schoolies Mark Reaburn says they’ve also identified a peculiar new trend sweeping through this year’s graduates.
“Proud to say the mullet is coming back!
“The mullet was appearing on quite a number of boys.
“We monitor the social media and the mullet is back… so welcome to schoolies 2019.
“Will it progress to 2020? We’ll wait and see,” Mr Reaburn said.
On a more serious note though, arrest and hospitalisation numbers have dropped considerably this year.
460 schoolies patients were treated by paramedics, with just under 10 percent transported to hospital.
Justin Payne from Queensland Ambulance says the emergency treatment centre was a success.
“The patients that we saw through the emergency treatment centre were actually extremely polite and well behaved.
“It was one of the better years as a response within our tent.
“We had no issues will school leavers being aggressive or outlandish to paramedics.
“So from our perspective, it was really well received, and great to treat young people in their environment and avoid going to hospital,” Mr Payne said.
A very similar report from police who only arrested 42 schoolies over the week – mostly for cannabis possession – around half that of last year’s group.
Chief Superintendent Craig Hanlon from Queensland Police said it was a very, very good schoolies year.
“There’s always going to be a very small group that’s going to come to the attention of police… we’ve dealt with them, and we’ve all moved on.
“The key from a police perspective and security perspective – is that there’ve been no acts of violence reported to us by schoolies.
“There’ve been some people who’ve made some mistakes in how they’re managed themselves, but they’re on the lower scale of offending,” Chief Superintendent Hanlon said.

HOPE AND GLORY A film review by Jonathan Gingrich Copyright 1987 Jonathan Gingrich
HOPE AND GLORY offers a unique, startling, and funny child's-eye view of life duing the Blitz. The destruction of the oppressive row house suburb transforms it into an amusement park for the young. But beyond this vision, there is little in the way of plot, and despite fine acting and a deft, economic staging, the movie must be carried by the characters, whom ultimately I found stilted and unconvincing.
On one level the movie is a comic slice of what life was really like during the Blitz, full of petty frustrations, antics, and concerns, mocking the "glory" of fighting the good fight. And it is the presumably autobiographical account of "hope," the rescue of young Bill from the clutches of suburban squalor. The comic bits are crisp, often brilliant, be they the discussion of whether the can of German jam is really poisoned, the adventure of a runaway barrage balloon, or the capture--by a motley crew of nervous neighbors--of a downed German pilot who reeks of confidence and sexuality.
But for me, the latter incident is the only moment the rampant randiness really works in the movie. And randy it is. Bill's elder sister is sexually active at 15 and pregnant by 16, the neighbor's wife boasts about her affairs and runs away with a Polish flyer, his mother's affair with the neighbor may be purely Platonic, his grandfather gets drunk every Christmas and toasts all the women he has bedded, the neighborhood boys line up to look in the panties of a girl who exchanges the favor for looted jewelry, but when his younger sister, perhaps 6, offers a sage comparison of the copulatory expertise of her elder sister and lover versus her parents, my patience ran out.
Nor do the others emerge unscathed.  His dad and the neighbor are both ineffectual, even impotent, the aunts all stuck in bad marriages, at least according to the grandfather, who is a raging, uninhibited spirit, full of crankiness and nastiness as well as love. In the second half of the movie, the family moves into the grandfather's house on the river, and young Bill is granted a Tom-Saywer-like escape from the gray suburbs with the guidance of his grandfather.  Besides, he constantly wears a white suit that made me think he was Italian.
Looking back, the movie has a number of merits I was not prepared to concede as I left the theater. But the constant sexuality was so integral to the texture of the story, and stuck out like a sore thumb, that I almost feel betrayed by a number of reviewers who failed to mention it at all. For me, Boorman is an "almost" director. He has wonderful vision here, in EXCALIBUR, and in THE EMERALD FOREST, but he has trouble tying up plots. In THE EMERALD FOREST, after weaving a wonderful modern fable of conflict between man and nature the whole thing runs out of yarn and he substitutes M-16s at 20 paces between natives in white hats and black hats. And here again, he has almost made a superior movie.

Tiny Sprite Editor
A tiny editor for editing tiny sprites - by Boris van Schooten - 30 May 2016
A lightweight yet full featured sprite editor consisting of a single HTML
page. No dependencies. Can be downloaded and run from a file. Distributed
under revised BSD license.
>>> Go to the sprite editor! <<<
I have been looking for a sprite editor for quickly creating small
(as in 8x8 to 16x16) pixelated sprites and tiles in a spritesheet. Further, I
wanted one that also works on Android. There are a number of good PC sprite
editors, but they are not tailored to this specific style of spriting. I also
looked for Android apps or online sprite editors, but found they mostly
suck.
So, I've made my own. To keep things simple, the editor assumes equally sized
small sprites arranged in a sprite sheet. Editing is based on a single sprite
within the sprite sheet.
Features:
- Works on any modern browser, also works well on mobile (tablet). It stores
your image persistently so that it doesn't get lost when reloading the page.
- Sprite sheet based editing
- Data transfer via: load/save PNG, import/export data URLs, Puzzlescript
- Fixed palette, colour pick, colour hex code entry
- Various operations, like flip, rotate, shift, insert/delete row,
add outline, flood fill, merge
- Undo/Redo
- Realtime tiling preview
- Realtime animation preview with pingpong option
- Onion skinning
- Configurable interface colours, edit zoom, preview zoom, onion skin
Known problems:
- Persistent storage will not work in IE if you run the app from a file
rather than a website.
- Firefox sometimes fails to load a data URL or even restore state with a
security exception. Generally this is resolved by reloading it.

Changes to the insert, the block, or the document insertion units will require this method to be called manually.
The attributes position, normal, rotation, text height, width factor, and oblique angle values includes the transformations applied to the insertion,
if required this method will calculate the proper values according to the ones defined by the attribute definition.
All the attribute values can be changed manually independently to its definition,
but, usually, you will want them to be transformed with the insert based on the local values defined by the attribute definition.
This method only applies to attributes that have a definition, some DXF files might generate attributes that have no definition in the block.
At the moment the attribute width factor and oblique angle are not calculated, this is applied to inserts with non uniform scaling.

Signals tagged as "optional" are not used when the -Xrs
option is specified to reduce signal usage. With this option fewer signals are used, although the VM installs its own signal handler for essential signals such as SIGSEGV
. Specifying this option means that the shutdown hook mechanism will not execute if the process receives a SIGQUIT
, SIGTERM
, SIGINT
, or SIGHUP
. Shutdown hooks will execute, as expected, if the VM terminates normally (that is, when the last non-daemon thread completes or the System.exit
method is invoked).
On Oracle Solaris 8 and 9 operating system, signals tagged as "configurable" are substituted when the -XX:+UseAltSigs
option is specified to use alternative signals. Starting with Oracle Solaris 10 operating system, this option is ignored, as the operating system reserves two additional signals (called SIGJVM1
and SIGJVM2
).
On Linux, the handler for SIGUSR1
cannot be overridden. SIGUSR2
is used to implement suspend and resume. However it is possible to specify an alternative signal to be used instead of SIGUSR2
. This is done by specifying the _JAVA_SR_SIGNUM
environment variable. If this environment variable is set, it must be set to a value larger than the maximum of SIGSEGV
and SIGBUS
.


RGB Color Layers in p5.js!
A step by step on how to separate an image by the maximum color in it's pixels. The end result will be a function where you can pass either 'RED', 'GREEN', or 'BLUE', as parameters and the output will be either the red, the green or the blue layer of the image used.
Image Loading
Since we are manipulating an image, our first step is going to be using the loadImage() method to upload an image to your sketch and setting up that image as your canvas!
- Use function preload() to load the Image onto your sketch.
- Set the canvas dimentions to the width and height of your image.
- Previous step will make sure image is displayed at the center (since we are setting it up as the canvas itself)
function preload() {
img = loadImage(imglist.starry);
}
function setup(){
createCanvas(img.width, img.height);
pixelDensity(1);
image(img, 0, 0, img.width, img.height);
}
function draw(){
}
ColorLayer( ) Function
Let's create out ColorLayer function. This function should take in a color name as a paramenter. Since this is where we are manipulating the image, we shoud copy and paste the out Basic code from draw into our function. Everything from loadPixels to updatePixels.
function ColorLayer(){
loadPixels();
for (var y = 0; y < height; y++){
for (var x = 0; x < width; x++){
var index = (x + y * width) * 4;
var r = pixels[index+0];
var g = pixels[index+1];
var b = pixels[index+2];
var a = pixels[index+3];
}
}
}
Maximum Color
Our color layers rely on the color with the highest value in that pixel, so lets create a new variable called maxi and the the max() method to determine which of the rgb values is the highest. Since we are analysing each pixel, lets create this variable inside our double for loop.
function ColorLayer(){
loadPixels();
for (var y = 0; y < height; y++){
for (var x = 0; x < width; x++){
var index = (x + y * width) * 4;
var r = pixels[index+0];
var g = pixels[index+1];
var b = pixels[index+2];
var a = pixels[index+3];
var maxi = max([r,g,b]);
}
}
}
Color Options
Our color options are RED, GREEN, and BLUE, so we are going to use those as the valid paramenters for our function. Lets create 3 if statements:
var maxi = max([r,g,b]);
if(color_name == "RED"){
}
if(color_name == "GREEN"){
}
if(color_name == "BLUE"){
}
If the color name is 'BLUE', we are going to keep all the pixels with max of blue and set all of the other ones to white.
if(color_name == "BLUE"){
if(maxi == b){
pixels[index+0] = r;
pixels[index+1] = g;
pixels[index+1] = b;
}
else{
pixels[index+0] = 255;
pixels[index+1] = 255;
pixels[index+1] = 255;
}
}
The same steps are true for 'RED' and 'GREEN'
if(color_name == "RED"){
if(maxi == r){
pixels[index+0] = r;
pixels[index+1] = g;
pixels[index+1] = b;
}
else{
pixels[index+0] = 255;
pixels[index+1] = 255;
pixels[index+1] = 255;
}
if(color_name == "GREEN"){
if(maxi == g){
pixels[index+0] = r;
pixels[index+1] = g;
pixels[index+1] = b;
}
else{
pixels[index+0] = 255;
pixels[index+1] = 255;
pixels[index+1] = 255;
}
Function Call
Our function is ready to go! All we need to do is call it. Let's do that in setup. Remember to pass in a color name!
function preload(){
img = loadImage(imglist.starry);
}
function setup(){
createCanvas(img.width, img.height);
pixelDensity(1);
image(img, 0, 0, img.width, img.height);
ColorLayer("BLUE");
}
function draw(){
}


In integrating a system that involves these modules, it must be the
case that they were created with the same base modules. That is to
say the pseudo-ops in flowgraphs must be the same abstraction that
was used to define the MLRisc intermediate
representation. Alternatively, we want sharing
constraints that assert that identity of modules used to
specialize other modules. In Standard ML, this is a complete
non-issue. A single line that says exactly that is all that is
needed to maintain consistency, and the module system does the rest
to ensure that the final system is built correctly.
In certain cases one wants to write a specific module for a
particular architecture. For instance it may be desirable to collapse
trap barriers on the DEC Alpha where it is legal to do so. The
INSTRUCTIONS interface is abstract with no built-in knowledge of
trap barriers as not all architectures have them.
Further the DEC Alpha has fairly unique trap barrier semantics,
that one may want to write an optimization module specific and
dedicated to the Alpha instruction set and architecture, and forget
about writing anything generic. In this case, the Standard ML module
system allows one to say that a specific abstraction actually is or
matches a more detailed interface. That is to say the INSTRUCTION
interface is really the DEC Alpha instruction set.


Data Protection Best Practices
By adjusting a few simple settings on your devices and accounts, you can maintain security against outside parties’, limit unwanted attempts to access your data, and ensure consent is not given to provide information to others.
Secure your browsing
Companies and websites track everything you do online. Every ad, social network button, and website collects information about your location, browsing habits, and more. This data reveals a lot about you and is valuable to advertisers to
pinpoint who you are as a person as well as your associated habits.
- Block Ads
- Extensions such as Adblock Plus or Ublock Origin allow for the blocking of
ads that are both targeted toward you and collecting data about you
- Disable cookies in your browser to ensure you are not followed beyond a webpage. Cookies can be blocked specifically, or entirely, from this extension or with similar software such as Privacy Badger
- HTTPS
- Ensure the website you are on has a small lock in the URL bar
- This ensures a secure tunnel between you and the website, so individuals on your network can not eavesdrop on your activity
- To guarantee that you are browsing securely, use an extension such as HTTPS Everywhere to automatically direct you to the secure version of a website.
- Many platforms allow users to opt-out of personal data collection, however, these settings are often difficult to find and doing so for each platform is not very feasible.
- Instead, use a service like Simple Opt-Out. It has direct links to opt-out instructions for major platforms such
as Facebook, Google, Netflix, Amazon, and more
Secure your accounts
In the past decade, data breaches and password leaks have struck companies such as Equifax, Facebook, Home Depot, Marriott, Target, Yahoo, and countless others. If you have online accounts, hackers have likely leaked data from at least
one of them.
To find out if your accounts have been compromised, check your email address on Have I Been Pwned?
- Use a password manager
- Allows storage of multiple complex passwords and syncs across devices
- Suggests strong passwords
- Use two-step authentication
- Ensures only you can access your account, even if your log-in is compromised
- Be notified immediately at attempts to log in
