You all know by now that there are untold hours of the sound of Mr Key babbling into a microphone available from the ResonanceFM Hooting Yard podcast hub. What may not be clear is that this treasure trove of twaddle is made available to you through the tireless work of unsung yet heroic figures who actually have a grasp of whizzbang 21st century technology (unlike Mr Key). So today I want to pay tribute to the current podcast maestro Marvin Suicide, in particular for his choice of photographic illustrations to each programme. This week, for the story Pancake Hints, he has excelled himself. Isn't this fantastic?

The Sixth Sense (1999) Bruce Willis, Haley Joel Osment, Toni Collette, Olivia Williams, Donnie Wahlberg, Glenn Fitzgerald, Mischa Barton, Trevor Morgan, Bruce Norris. Music by James Newton Howard. Written and directed by M. Night Shyamalan. 107 minutes. Rated PG-13, 3.5 stars (out of five stars)
Review by Ed Johnson-Ott, NUVO Newsweekly www.nuvo-online.com Archive reviews at http://us.imdb.com/M/reviews_by?Edward+Johnson-ott To receive reviews by e-mail at no charge, send subscription requests to<EMAIL_ADDRESS>When a whopping five films went into wide release on August 6, industry pundits were unsure which ones the public would embrace. "The Iron Giant" was the best reviewed film of the year, but, sadly, most adults still consider animated movies "kid's stuff" and children rarely get juiced up for a flick unless they see its name plastered on a Happy Meal. "The Thomas Crown Affair" was glossy, sexy fun, but with the huge success of "Runaway Bride," it seemed a little soon for another romance to hit big. The political farce "Dick" and the superhero spoof "Mystery Men" both appeared too quirky for mainstream audiences and, in the wake of "The Blair Witch Project" phenomenon, little attention was paid to "The Sixth Sense," the "other" horror film.
Less than two weeks later, "The Sixth Sense" has become the first release since "Star Wars: The Phantom Menace" to hold the number one spot at the box office for more than a week, raking in $70 million in just 10 days. For a quiet little ghost story starring an actor best known for smirking between explosions in action films, this is extraordinary. So what exactly is the deal with "The Sixth Sense?"
A few minutes into the press screening of the movie, I jotted the words "deliberately paced" in my notebook. Mid-way through, I crossed out "deliberate" and replaced it with "dull." But after the striking conclusion of the story, I spent a long time in the lobby with a fellow critic, enthusiastically discussing the film. The following Saturday, at a nationwide sneak preview, we both went to see it again.
In its own way, "The Sixth Sense" is as innovative as "The Blair Witch Project." Writer and director M. Night Shyamalan carefully establishes a moody, extremely low-key tone, only to smack you upside the head when you least expect it. You feel compelled to watch the movie another time, to see how it holds up in light of the things you learned along the way. This is one of those rare productions that actually plays better the second time around.
It begins when a former patient (Donnie Wahlberg) breaks into the Philadelphia home of child psychologist Dr. Malcolm Crowe (Bruce Willis) and his wife, Anna (Olivia Williams). The frantic young man accuses the doctor of failing him, then abruptly shoots Malcolm, just before turning the gun on himself.
Cut to the following autumn. Malcolm and Anna's marriage has taken a drastic turn since the tragedy. Both are sullen and non-communicative, with Anna focusing most of her attention on her work at an antique shop and Malcolm focusing most of his on a new case. Eight-year-old Cole Sear (Haley Joel Osment) is an extremely troubled boy. His single mother Lynn (Toni Collette) is at a loss to understand the behavior of her son, a bright kid who hoards religious figurines, creates alarming drawings and constantly surveys his surroundings in fear. The doctor works cautiously with the wary child, hoping trying to establish a bond of trust. After many meetings, Cole finally turns to Malcolm and reveals his secret. "I see dead people," he whispers, desperately looking to the doctor for help.
That's all you need to know. If, like me, you find the proceedings overly slow and ponderous, hang in there, because your patience will be rewarded with a whale of a payoff. "The Sixth Sense" is one of the better ghost stories to come along in quite some time, for those willing to cooperate with Shyamalan's methodical presentation.
The director uses the Philadelphia settings well, creating a stately, ominous feel accented by James Newton Howard's creepy, but unobtrusive score. Shyamalan ends many scenes by fading to black, a stylistic move that seems like a slightly overdone affectation at first, but in fact proves essential to the story. His visualizations of the dead are less successful. The natural lighting is too matter-of-fact for the ghosts to appear authentic; instead of seeming otherworldly, they just look like actors in makeup.
His key players compensate for the unconvincing spooks. While "Rushmore's" Olivia Williams is given little to do and Toni Collette only gets a couple of scenes to display her formidable talents, Bruce Willis offers an appropriately restrained performance and Haley Joel Osment is exceptional. The young actor does fine work, nimbly projecting intelligence, fear and desperation without ever overdoing it.
Congratulations to those who have made "The Sixth Sense" a box office smash. You have shown that mass audiences sometimes do choose a small, well-told story over standard, mega-hyped summer dreck. Now, while you're making such good decisions, how about giving "The Iron Giant" a chance as well?

Working part-time with the EEE department as a tour guide for prospective students who are interviewing at Imperial.
Coordinating and organizing events within the Imperial College Robotics Society (ICRS). These included over fall 2019 talks, ice skating, christmas dinner, movie night.
I enjoy being part of ICRS in general, as there are always amazing projects going around in the lab, not mentioning a community of innovators
Links: ICRS WebsiteThe task was to prototype a Drilling Program quick-look Progressive Web App (PWA), that will enable drilling engineers to review their reports faster and securely, in any network conditions (slow or offline), on any device (desktop or mobile). This PWA prototype would be an extension of Reporting, one of DrillPlan’s fundamental tools (a Schlumberger software), as well as a research into building simple, yet effective cross-platform applications
The team was satisfied with the delivered prototype. It was therefore deployed on production servers and is currently accessible by Schlumberger DrillPlan clients. Further investigation is required to support new customizations and features, as well as define diverse limitations.
Overall, it was a great experience. Beside learning new technologies, I have developped new work ethics within the Schlumberger supportive and professional environment as well as linked Software Engineering to real-world applications in a large corporate.
Technologies used: Angular 7, Typescript, JavasScript, HTML, CSS, GIT Source Control, Progressive Web Apps, Service Worker
Links: Schlumberger Website | Internship ReportOne of the company’s projects was a customized Moodle app (mobile application to monitor school system from grades to assignments and messaging service). I had to implement an extension to an existing project.
Built a skeleton for parent-users to access their children grades, calendar, and agenda from the mobile app, using HTML, CSS, Node JS.
Links: NEEDS WebsiteThe last summer before starting college, I have worked with Amideast as a teaching assistant, where I coached student for the SAT Math tests as well as assited them with their college applications.
It was a great experience to work alongside younger students and help them reach their goals, as well as improve communication and tutoring skills.
Links: Amideast WebsiteI have conducted aerial video shootings for four Lebanese power plants as well as a power plant inauguration as well as edited and created diverse videos.
This was my first officially paid job! I learned the fundamental tricks necessary to obtain good shots (angle, rotation, speed, etc...).
I have developed from scratch a Java database to manage student profiles. Focused mostly on the user approach of the product and the data structure.
I later took the project to a higher level by adding address, phone number, and blood type categories: in a hospital emergency, the closest potential blood donor could be contacted.

How Sonko Siphoned Millions From Nairobi - EACC
by Emmanuel GithukuNairobi Governor Mike Sonko is a man in trouble again after the EACC unearthed ways he has allegedly been using to siphon cash from the County Government of Nairobi's coffers.
After months of investigations, the anti-corruption agency on Friday, November 22, flagged transactions through which it claimed Governor Sonko diverted millions of shillings to his personal bank accounts.
According to a report by The Standard who quoted the EACC, Sonko was involved in a complex web of kickbacks from the companies that had been awarded tenders by his government.
EACC alleged that a conspiracy with private companies saw the county boss pocket Ksh39 million through the said transactions.
Simon Cherpka, EACC's forensic investigator, claimed that in one instance the governor had Ksh27.4 million wired to his account from three companies, which had been awarded multi-million shilling contracts under questionable circumstances by the county government.
Between June 2017 and February 2019, investigations revealed massive fraud, procurement irregularities, misappropriation of public funds and conflict of interest through inconsistent and exaggerated payments made to individuals and proxy companies at City Hall,” stated Cherpka in an affidavit filed in court
The investigator further claimed that companies were awarded tenders without following due process and millions of shillings found their way back to the accounts of the county head.
A report by Citizen TV stated that the anti-corruption watchdog named Hardi Enterprises, Yiro Enterprises Jakoy Enterprises, Flexilease enterprises, Acacia Equipment (K) Ltd, Aende Group Limited and Tusma Trading Company as those used in the scheme.
Cherpka believed that in a period of five months between October 2018 and March 2019, Hardi Enterprises received a total of Ksh357 million from the county for solid waste collection and disposal.

Chinese Commerce Ministry Says PRC, US Discuss Phase One of Trade Deal
BEIJING (Sputnik) - The chief trade negotiators from China and the United States, Vice Premier Liu He, US Trade Representative Robert Lighthizer, and US Treasury Secretary Steven Mnuchin have had a phone conversation regarding the first phase of a new trade agreement, the Chinese Commerce Ministry said.
According to the Ministry, the discussion was requested by the US side.
"The sides had a constructive discussion about each other's primary concerns regarding the phase one of the trade agreement, and agreed to remain in close contact", the Ministry said in a statement.
China is currently engaged in a trade dispute with the United States, which accuses Beijing of unfair commercial practices.
Since June last year, the two countries have exchanged several rounds of import duties and subsequent talks to settle their trade-related disagreements.

Event Listener with C++
Dear Infinispan community,
as announced in a previous post, starting from version 8.1.0 also the C++/C# clients can receive and process Infinispan events.
Here’s an example of usage of C++ event listeners that, with a good dose of imagination, pretends to be a customer behavior tracking system for our store chain (don’t take this too seriously, we’re just trying to add some fiction).
As a first requirement our tracking system will record every single purchase made in our stores. How many stores we have? 1, 100, millions? It doesn’t matter: we’re backed with an Infinispan data grid. This is version 0.x and hence the checker must use the keyboard to enter all the needed information.
As you can see our entry key is a concatenation of the product name and the timestamp and the entry value is an unstructured string, maybe too simply but it could work for now. Seems we are at a good point: we have the data and we can do analytics on it, so far so good but now our boss makes a new request: he wants a runtime monitor on how’s the sales performance. That’s a perfect request to be fulfilled with event listener: the monitor application will be an Hotrod C++ client that registers a client listener on the server and receives and show on the boss’s laptop the data flow. A client listener, once registered on the server, can receive events related to: creation, modification, deletion, expiration of cache entries; in our example only the creation and expiration events are processed (expired events can be useful to do some moving average statistics?). Following a snip of code that creates and registers a listener that writes the events key on the stdout.
You can git this quickstart here [1]. On startup a multiple choice menu is shown with all the available operations. Running several instances you can act as the checker (data entry) or the boss (installing the listener and seeing the events flow).
Filters
Again so far so good, but then the marketing department ask support to do targeted advertising like: soliciting customers that bought product Y to buy product X. Let’s suppose that X="harmonica" and Y="hiking boots" (it’s a well known fact of life that in the high mountains you feel the desire to play an harmonica).
To do that we register on the server another listener, but this time we’re not interested in the whole flow of purchase data: to run our marketing campaign, we only interested in cache entries having the key starting with "hiking". The Infinispan server can filter out events for us, if we pass in the AddClientListener operation the name of the wanted filter along with any configuration arguments.
Filter are java classes that must be deployed into the Infinispan server (more here [2])
and converters
Predefined events contain very few information: basically the event type and the entry key, this to prevent to flood the network spreading around very long entry values. Users can override this limitation using a converter, that is a java class deployed into the server, that can create custom events containing every data needed by the application.
As in the previous case, we pass into the add operation the name of the converter and the configuration arguments, any.
That’s all guys, let us know your feedback: do you like it? Could be better? Tell us how it can be improved creating an issue [3], or fork and improve it yourself [4]!
Thanks for reading and enjoy! The Infinispan Team

Stilettos by State: a Gilt Infographic
While working on our headlines-making preemptive shipping initiative, Gilt Principal Data Scientist Igor Elbert got a bit curious about whether certain fashion preferences might be regional or universal (or not). He and Gilt Data Analyst Debbie Chung had some hunches about how favorite styles, colors, etc. might differ around the U.S. and Puerto Rico and, like any good data sleuths, started exploring.
First, they looked at dress colors to see which ones were most popular in which U.S. regions, and found out that black is, um, still the “new black” in every corner of the country. Then they explored how high-heel heights varied among U.S. states, and noticed that the range was pretty substantial. The results of their findings are here in this infographic, created by Rhianon Cha-os.
While doing this research, Igor had to learn more about women’s shoes than he’d otherwise like to admit–addressing the heel-height aspect of “ballet flats,” “booties,” “boots,” etc. and figuring out their differences. But Debbie and Igor’s hard work (and Igor’s slight discomfort) paid off: Now we have a look at how tastes in high heels differ across the U.S. and in Puerto Rico!

IndPrinciplesInduction Principles
Set Warnings "-notation-overridden,-parsing".
Require Export ProofObjects.
Basics
Check nat_ind.
(* ===> nat_ind :
forall P : nat -> Prop,
P 0 ->
(forall n : nat, P n -> P (S n)) ->
forall n : nat, P n *)
The induction tactic is a straightforward wrapper that, at its
core, simply performs apply t_ind. To see this more clearly,
let's experiment with directly using apply nat_ind, instead of
the induction tactic, to carry out some proofs. Here, for
example, is an alternate proof of a theorem that we saw in the
Basics chapter.
Theorem mult_0_r' : ∀ n:nat,
n * 0 = 0.
Proof.
apply nat_ind.
- (* n = O *) reflexivity.
- (* n = S n' *) simpl. intros n' IHn'. rewrite → IHn'.
reflexivity. Qed.
This proof is basically the same as the earlier one, but a
few minor differences are worth noting.
First, in the induction step of the proof (the "S" case), we
have to do a little bookkeeping manually (the intros) that
induction does automatically.
Second, we do not introduce n into the context before applying
nat_ind — the conclusion of nat_ind is a quantified formula,
and apply needs this conclusion to exactly match the shape of
the goal state, including the quantifier. By contrast, the
induction tactic works either with a variable in the context or
a quantified variable in the goal.
These conveniences make induction nicer to use in practice than
applying induction principles like nat_ind directly. But it is
important to realize that, modulo these bits of bookkeeping,
applying nat_ind is what we are really doing.
Exercise: 2 stars, optional (plus_one_r')
Complete this proof without using the induction tactic.Theorem plus_one_r' : ∀ n:nat,
n + 1 = S n.
Proof.
(* FILL IN HERE *) Admitted.
t_ind : ∀ P : t → Prop,
... case for c1 ... →
... case for c2 ... → ...
... case for cn ... →
∀ n : t, P n
The specific shape of each case depends on the arguments to the
corresponding constructor. Before trying to write down a general
rule, let's look at some more examples. First, an example where
the constructors take no arguments:
... case for c1 ... →
... case for c2 ... → ...
... case for cn ... →
∀ n : t, P n
Inductive yesno : Type :=
| yes : yesno
| no : yesno.
Check yesno_ind.
(* ===> yesno_ind : forall P : yesno -> Prop,
P yes ->
P no ->
forall y : yesno, P y *)
Exercise: 1 star, optional (rgb)
Write out the induction principle that Coq will generate for the following datatype. Write down your answer on paper or type it into a comment, and then compare it with what Coq prints.Inductive rgb : Type :=
| red : rgb
| green : rgb
| blue : rgb.
Check rgb_ind.
Inductive natlist : Type :=
| nnil : natlist
| ncons : nat → natlist → natlist.
Check natlist_ind.
(* ===> (modulo a little variable renaming)
natlist_ind :
forall P : natlist -> Prop,
P nnil ->
(forall (n : nat) (l : natlist),
P l -> P (ncons n l)) ->
forall n : natlist, P n *)
Exercise: 1 star, optional (natlist1)
Suppose we had written the above definition a little differently:Inductive natlist1 : Type :=
| nnil1 : natlist1
| nsnoc1 : natlist1 → nat → natlist1.
Now what will the induction principle look like? ☐
From these examples, we can extract this general rule:
- The type declaration gives several constructors; each corresponds to one clause of the induction principle.
- Each constructor c takes argument types a1 ... an.
- Each ai can be either t (the datatype we are defining) or some other type s.
- The corresponding case of the induction principle says:
- "For all values x1...xn of types a1...an, if P holds for each of the inductive arguments (each xi of type t), then P holds for c x1 ... xn".
Exercise: 1 star, optional (byntree_ind)
Write out the induction principle that Coq will generate for the following datatype. (Again, write down your answer on paper or type it into a comment, and then compare it with what Coq prints.)Inductive byntree : Type :=
| bempty : byntree
| bleaf : yesno → byntree
| nbranch : yesno → byntree → byntree → byntree.
Exercise: 1 star, optional (ex_set)
Here is an induction principle for an inductively defined set.
ExSet_ind :
∀ P : ExSet → Prop,
(∀ b : bool, P (con1 b)) →
(∀ (n : nat) (e : ExSet), P e → P (con2 n e)) →
∀ e : ExSet, P e
Give an Inductive definition of ExSet:
∀ P : ExSet → Prop,
(∀ b : bool, P (con1 b)) →
(∀ (n : nat) (e : ExSet), P e → P (con2 n e)) →
∀ e : ExSet, P e
Inductive ExSet : Type :=
(* FILL IN HERE *)
.
Polymorphism
Inductive list (X:Type) : Type :=
| nil : list X
| cons : X → list X → list X.
is very similar to that of natlist. The main difference is
that, here, the whole definition is parameterized on a set X:
that is, we are defining a family of inductive types list X,
one for each X. (Note that, wherever list appears in the body
of the declaration, it is always applied to the parameter X.)
The induction principle is likewise parameterized on X:
| nil : list X
| cons : X → list X → list X.
list_ind :
∀ (X : Type) (P : list X → Prop),
P [] →
(∀ (x : X) (l : list X), P l → P (x :: l)) →
∀ l : list X, P l
Note that the whole induction principle is parameterized on
X. That is, list_ind can be thought of as a polymorphic
function that, when applied to a type X, gives us back an
induction principle specialized to the type list X.
∀ (X : Type) (P : list X → Prop),
P [] →
(∀ (x : X) (l : list X), P l → P (x :: l)) →
∀ l : list X, P l
Exercise: 1 star, optional (tree)
Write out the induction principle that Coq will generate for the following datatype. Compare your answer with what Coq prints.Inductive tree (X:Type) : Type :=
| leaf : X → tree X
| node : tree X → tree X → tree X.
Check tree_ind.
Exercise: 1 star, optional (mytype)

(∀ m : mytype X, P m →

Exercise: 1 star, optional (foo)

(∀ f1 : nat → foo X Y,
(∀ n : nat, P (f1 n)) → P (quux X Y f1)) →
∀ f2 : foo X Y, P f2
☐
∀ (X Y : Type) (P : foo X Y → Prop),
(∀ x : X, P (bar X Y x)) →
(∀ y : Y, P (baz X Y y)) →
(∀ f1 : nat → foo X Y,
(∀ n : nat, P (f1 n)) → P (quux X Y f1)) →
∀ f2 : foo X Y, P f2
Exercise: 1 star, optional (foo')

| C1 : list X → foo' X → foo' X
| C2 : foo' X.
What induction principle will Coq generate for foo'? Fill
in the blanks, then check your answer with Coq.)
☐
foo'_ind :
∀ (X : Type) (P : foo' X → Prop),
(∀ (l : list X) (f : foo' X),
_______________________ →

∀ f : foo' X, ________________________
Induction Hypotheses
∀ P : nat → Prop,
P 0 →
(∀ n : nat, P n → P (S n)) →
∀ n : nat, P n
is a generic statement that holds for all propositions
P (or rather, strictly speaking, for all families of
propositions P indexed by a number n). Each time we
use this principle, we are choosing P to be a particular
expression of type nat→Prop.
P 0 →
(∀ n : nat, P n → P (S n)) →
∀ n : nat, P n
Definition P_m0r (n:nat) : Prop :=
n * 0 = 0.
... or equivalently:
Definition P_m0r' : nat→Prop :=
fun n ⇒ n * 0 = 0.
Now it is easier to see where P_m0r appears in the proof.
Theorem mult_0_r'' : ∀ n:nat,
P_m0r n.
Proof.
apply nat_ind.
- (* n = O *) reflexivity.
- (* n = S n' *)
(* Note the proof state at this point! *)
intros n IHn.
unfold P_m0r in IHn. unfold P_m0r. simpl. apply IHn. Qed.
This extra naming step isn't something that we do in
normal proofs, but it is useful to do it explicitly for an example
or two, because it allows us to see exactly what the induction
hypothesis is. If we prove ∀ n, P_m0r n by induction on
n (using either induction or apply nat_ind), we see that the
first subgoal requires us to prove P_m0r 0 ("P holds for
zero"), while the second subgoal requires us to prove ∀ n',
P_m0r n' → P_m0r (S n') (that is "P holds of S n' if it
holds of n'" or, more elegantly, "P is preserved by S").
The induction hypothesis is the premise of this latter
implication — the assumption that P holds of n', which we are
allowed to use in proving that P holds for S n'.
More on the induction Tactic
- If P n is some proposition involving a natural number n, and
we want to show that P holds for all numbers n, we can
reason like this:
- show that P O holds
- show that, if P n' holds, then so does P (S n')
- conclude that P n holds for all n.
Theorem plus_assoc' : ∀ n m p : nat,
n + (m + p) = (n + m) + p.
Proof.
(* ...we first introduce all 3 variables into the context,
which amounts to saying "Consider an arbitrary n, m, and
p..." *)
intros n m p.
(* ...We now use the induction tactic to prove P n (that
is, n + (m + p) = (n + m) + p) for _all_ n,
and hence also for the particular n that is in the context
at the moment. *)
induction n as [| n'].
- (* n = O *) reflexivity.
- (* n = S n' *)
(* In the second subgoal generated by induction -- the
"inductive step" -- we must prove that P n' implies
P (S n') for all n'. The induction tactic
automatically introduces n' and P n' into the context
for us, leaving just P (S n') as the goal. *)
simpl. rewrite → IHn'. reflexivity. Qed.
It also works to apply induction to a variable that is
quantified in the goal.
Theorem plus_comm' : ∀ n m : nat,
n + m = m + n.
Proof.
induction n as [| n'].
- (* n = O *) intros m. rewrite <- plus_n_O. reflexivity.
- (* n = S n' *) intros m. simpl. rewrite → IHn'.
rewrite <- plus_n_Sm. reflexivity. Qed.
Note that induction n leaves m still bound in the goal —
i.e., what we are proving inductively is a statement beginning
with ∀ m.
If we do induction on a variable that is quantified in the goal
after some other quantifiers, the induction tactic will
automatically introduce the variables bound by these quantifiers
into the context.
Theorem plus_comm'' : ∀ n m : nat,
n + m = m + n.
Proof.
(* Let's do induction on m this time, instead of n... *)
induction m as [| m'].
- (* m = O *) simpl. rewrite <- plus_n_O. reflexivity.
- (* m = S m' *) simpl. rewrite <- IHm'.
rewrite <- plus_n_Sm. reflexivity. Qed.
Exercise: 1 star, optional (plus_explicit_prop)
Rewrite both plus_assoc' and plus_comm' and their proofs in the same style as mult_0_r'' above — that is, for each theorem, give an explicit Definition of the proposition being proved by induction, and state the theorem and proof in terms of this defined proposition.(* FILL IN HERE *)
Induction Principles in Prop
Inductive ev : nat → Prop :=
| ev_0 : ev 0
| ev_SS : ∀ n : nat, ev n → ev (S (S n)).
...to give rise to an induction principle that looks like this...
| ev_0 : ev 0
| ev_SS : ∀ n : nat, ev n → ev (S (S n)).
ev_ind_max : ∀ P : (∀ n : nat, ev n → Prop),
P O ev_0 →
(∀ (m : nat) (E : ev m),
P m E →
P (S (S m)) (ev_SS m E)) →
∀ (n : nat) (E : ev n),
P n E
... because:
P O ev_0 →
(∀ (m : nat) (E : ev m),
P m E →
P (S (S m)) (ev_SS m E)) →
∀ (n : nat) (E : ev n),
P n E
- Since ev is indexed by a number n (every ev object E is
a piece of evidence that some particular number n is even),
the proposition P is parameterized by both n and E —
that is, the induction principle can be used to prove
assertions involving both an even number and the evidence that
it is even.
- Since there are two ways of giving evidence of evenness (ev
has two constructors), applying the induction principle
generates two subgoals:
- We must prove that P holds for O and ev_0.
- We must prove that, whenever n is an even number and E
is an evidence of its evenness, if P holds of n and
E, then it also holds of S (S n) and ev_SS n E.
- We must prove that P holds for O and ev_0.
- If these subgoals can be proved, then the induction principle tells us that P is true for all even numbers n and evidence E of their evenness.
∀ P : nat → Prop,
... →
∀ n : nat,
even n → P n
For this reason, Coq actually generates the following simplified
induction principle for ev:
... →
∀ n : nat,
even n → P n
Check ev_ind.
(* ===> ev_ind
: forall P : nat -> Prop,
P 0 ->
(forall n : nat, ev n -> P n -> P (S (S n))) ->
forall n : nat,
ev n -> P n *)
In particular, Coq has dropped the evidence term E as a
parameter of the the proposition P.
In English, ev_ind says:
As expected, we can apply ev_ind directly instead of using
induction. For example, we can use it to show that ev' (the
slightly awkward alternate definition of evenness that we saw in
an exercise in the \chap{IndProp} chapter) is equivalent to the
cleaner inductive definition ev:
- Suppose, P is a property of natural numbers (that is, P n is
a Prop for every n). To show that P n holds whenever n
is even, it suffices to show:
- P holds for 0,
- for any n, if n is even and P holds for n, then P holds for S (S n).
- P holds for 0,
Theorem ev_ev' : ∀ n, ev n → ev' n.
Proof.
apply ev_ind.
- (* ev_0 *)
apply ev'_0.
- (* ev_SS *)
intros m Hm IH.
apply (ev'_sum 2 m).
+ apply ev'_2.
+ apply IH.
Qed.
Proof.
apply ev_ind.
- (* ev_0 *)
apply ev'_0.
- (* ev_SS *)
intros m Hm IH.
apply (ev'_sum 2 m).
+ apply ev'_2.
+ apply IH.
Qed.
The precise form of an Inductive definition can affect the
induction principle Coq generates.
For example, in chapter IndProp, we defined ≤ as:
(* Inductive le : nat -> nat -> Prop :=
| le_n : forall n, le n n
| le_S : forall n m, (le n m) -> (le n (S m)). *)
This definition can be streamlined a little by observing that the
left-hand argument n is the same everywhere in the definition,
so we can actually make it a "general parameter" to the whole
definition, rather than an argument to each constructor.
Inductive le (n:nat) : nat → Prop :=
| le_n : le n n
| le_S : ∀ m, (le n m) → (le n (S m)).
Notation "m ≤ n" := (le m n).
The second one is better, even though it looks less symmetric.
Why? Because it gives us a simpler induction principle.
Check le_ind.
(* ===> forall (n : nat) (P : nat -> Prop),
P n ->
(forall m : nat, n <= m -> P m -> P (S m)) ->
forall n0 : nat, n <= n0 -> P n0 *)
Formal vs. Informal Proofs by Induction
Induction Over an Inductively Defined Set
- Theorem: <Universally quantified proposition of the form
"For all n:S, P(n)," where S is some inductively defined
set.>
Proof: By induction on n.<one case for each constructor c of S...>
- Suppose n = c a1 ... ak, where <...and here we state
the IH for each of the a's that has type S, if any>.
We must show <...and here we restate P(c a1 ... ak)>.
<go on and prove P(n) to finish the case...>
- <other cases similarly...> ☐
- Suppose n = c a1 ... ak, where <...and here we state
the IH for each of the a's that has type S, if any>.
We must show <...and here we restate P(c a1 ... ak)>.
- Theorem: For all sets X, lists l : list X, and numbers
n, if length l = n then index (S n) l = None.
Proof: By induction on l.
- Suppose l = []. We must show, for all numbers n,
that, if length [] = n, then index (S n) [] =
None.
This follows immediately from the definition of index.
- Suppose l = x :: l' for some x and l', where
length l' = n' implies index (S n') l' = None, for
any number n'. We must show, for all n, that, if
length (x::l') = n then index (S n) (x::l') =
None.
Let n be a number with length l = n. Sincelength l = length (x::l') = S (length l'),it suffices to show thatindex (S (length l')) l' = None.But this follows directly from the induction hypothesis, picking n' to be length l'. ☐
- Suppose l = []. We must show, for all numbers n,
that, if length [] = n, then index (S n) [] =
None.
Induction Over an Inductively Defined Proposition
- Theorem: <Proposition of the form "Q → P," where Q is
some inductively defined proposition (more generally,
"For all x y z, Q x y z → P x y z")>
Proof: By induction on a derivation of Q. <Or, more generally, "Suppose we are given x, y, and z. We show that Q x y z implies P x y z, by induction on a derivation of Q x y z"...><one case for each constructor c of Q...>
- Suppose the final rule used to show Q is c. Then
<...and here we state the types of all of the a's
together with any equalities that follow from the
definition of the constructor and the IH for each of
the a's that has type Q, if there are any>. We must
show <...and here we restate P>.
<go on and prove P to finish the case...>
- <other cases similarly...> ☐
- Suppose the final rule used to show Q is c. Then
<...and here we state the types of all of the a's
together with any equalities that follow from the
definition of the constructor and the IH for each of
the a's that has type Q, if there are any>. We must
show <...and here we restate P>.
- Theorem: The ≤ relation is transitive — i.e., for all
numbers n, m, and o, if n ≤ m and m ≤ o, then
n ≤ o.
Proof: By induction on a derivation of m ≤ o.
- Suppose the final rule used to show m ≤ o is
le_n. Then m = o and we must show that n ≤ m,
which is immediate by hypothesis.
- Suppose the final rule used to show m ≤ o is
le_S. Then o = S o' for some o' with m ≤ o'.
We must show that n ≤ S o'.
By induction hypothesis, n ≤ o'.
But then, by le_S, n ≤ S o'. ☐
- Suppose the final rule used to show m ≤ o is
le_n. Then m = o and we must show that n ≤ m,
which is immediate by hypothesis.

GORDY A film review by Chad Polenz Copyright 1997 Chad Polenz
* (out of 4 = poor) 1995, G, 90 minutes [1 hour, 30 minutes] [comedy] starring: Michael Roescher (Hank Royce), Kristy Young (Jinnie Sue MaCallister), Justin Garms (voice of Gordy), James Donadio (Gilbert Sipes), written by Leslie Stevens, Jay Sommers, Dick Chevillat, produced by Sybil Robson, directed by Mark Lewis.
"Gordy" is not a movie, it is a 90-minute-long "Sesame Street" skit, and a very bad one at that.
I'm sure children are the target audience of this movie, but only kids under the age of five may be able to tolerate it. It is the story of a farm a piglet named Gordy (voiced by Garms), whose family has been taken away to "up north," which we know means death. Of course we can hear the animals talk to each other, and they actually went to the trouble of attempting to sync the voices with their mouths but it comes out terrible. Actually, it's almost funny in a way.
The only remotely interesting and likable character soon appears, a little girl named Jinnie Sue MaCallister (Young) who sees Gordy on the back of a truck and essentially steals him. Jinnie is a country singer and the film goes off on a huge tangent to show her little concert and the people dancing to it. What is the point of this? Maybe she is one of the producer's relatives and they wanted to show her on camera to promote her or something.
We then cut to a huge social gathering and drop in on another young kid named Hank Royce (Roescher) who is sad because his divorced mother is dating. He leaves the party and meets Jinnie Sue, but he accidentally falls in a pool (probably because he was sitting on the diving board with a $200 suit on - nah, didn't see that one coming!), starts to drown, and is miraculously saved as Gordy pushes an inflatable float over to him and saves him.
If this had not been insanely stupid already the story quickly changes when Jinnie gives Gordy to Hank who then ends up becoming the CEO of a food processing corporation when Hank's grandfather, the original CEO, dies and leaves his fortune to Hank... and Gordy!
Of course there must be a villain, but even this villain (Donadio as Sipes) isn't that evil.
At times "Gordy" is tolerable to watch, thus earning it one star and not the dreaded "z-." But it's just so unbelievably boring, cliche, dumb, unfunny, corny, and just plain bad it may scare children, it certainly disturbed me.

What is E-Waste?
The term “E-waste” is an informal name for electronic devices, parts, products, etc. that have approached the end of their usefulness. Computers, televisions, copiers, stereos, VCRs, fax machines, and car batteries for example, that no longer work, or are no longer useful, are considered “E-waste.”
Why is E-Waste Harmful?
In 2009, 430 million new consumer electronics were sold in the U.S., while 5 million tons were in storage, and 2.37 million tons were ready for end of life management. Of the 2.37 million tons of E-waste in 2009, only about 12.5% was recycled. That leaves 2,073,750 tons, or 4,147,500,000 pounds of broken or useless electronics unaccounted for. It is what is done with this 4,147,500,000 pounds of unaccounted for E-waste that makes it so harmful to not only the environment, but to the people who live in third world countries. These statistics are in the U.S. alone. Worldwide 20 to 50 million metric tons of E-waste are disposed each year in landfills or incinerators, which can release harmful toxins into the air.

I did some investigation on this, and this seems to be localized to just CD call numbers. This leads me to think it's something to do with how call numbers are normalized in the indexer.
See<PHONE_NUMBER>506421 for a record with a call number with a $k Oversize that shows up correctly.

by None at 2022-09-26 12:43:41.@eliotjordan I'm sorry to come back to this--it looks like I need to reverse myself. We need to display the external name in pulfalight, but we need to pass to Aeon the internal name (i.e. the code) for requesting. It looks like right now, what's getting passed to Aeon is the external name. Could you fix that? Thanks, and sorry again!

by Eliot Jordan at 2022-09-26 14:29:59.subscribed
by Eliot Jordan at 2022-09-26 14:29:59.@eliotjordan Are you sure? Those codes are the ones which Aeon uses to decide which queue to put things into - I think the only valid values are RBSC
, MUDD
, and Engineering Library
(and I'm not 100% sure Engineering Library is right either.)
There's also location_codes.yml
and storage_notes.yml
which might be where we want the longer form names?
@tpendragon No I'm not sure. @regineheberlein Your Slack message from this morning seems to imply something different.
We want to make sure pulfalight passes the codes, e.g. scamudd to Aeon for requesting.
Please advise.
I see now that the UI text for the locations goes here: https://github.com/pulibrary/pulfalight/blob/main/config/location_codes.yml
Not sure about the physloc codes. Maybe something like:
scamudd: 'scamudd'
if those codes are what Aeon is expecting.
So does pulfalight map the Aeon "sites", i.e. pickup locations? If so, they are: | site | physloc | Alma label | --- | --- | --- RBSC | scarcpxm | 'Manuscripts Remote Storage (ReCAP). Special Collections Use Only' RBSC | scactsn | 'Cotsen Children’s Library Archival. Special Collections Use Only' RBSC | scagax | 'Graphic Arts Archival. Special Collections Use Only' RBSC | scamss | 'Manuscripts Archival. Special Collections Use Only' RBSC | scawa | 'Western Americana Archival. Special Collections Use Only' RBSC | scaex | 'Rare Books Archival. Special Collections Use Only' RBSC | scahsvm | 'Manuscripts High Security Archival. Special Collections Use Only' MUDD | scamudd | 'Mudd Archival. Special Collections Use Only' RBSC | scathx | 'Theater Archival. Special Collections Use Only'
Ah, okay. Pulfalight does two things:
Map physloc
to SITE:
and
and also map container locations to Location
and
I think you need some tests in https://github.com/pulibrary/pulfalight/blob/main/spec/values/aeon_request_spec.rb to
A) Make sure Site gets populated for those physloc codes B) Make sure Location replaces those sca codes with the other codes.
The goal is, in Aeon, for scahsvm
to have a Location
of hsvm
and a Site
of RBSC
, for instance, yeah?
Alternatively, if we want the UI and Aeon to always act as if "sca" isn't in a location code, we could just index without those - if it finds "scaxxx" it indexes "xxx"
Oh, that is so much better! Yes, that would be ideal. The raison d'etre of the new codes is purely to allow us to have things in the catalog BUT not have them requestable from there; they are "twins" to existing location codes in each case. So indexing with out the sca
- prefix sounds like an elegant solution. That way bibdata indexes with the prefix and facilitates disallowing requesting; pulfalight indexes without prefix and sends to Aeon as usual.

Currently the online content icon has a single color: #636363. Is this correct? Yes, that is correct for the online content icon when the component has online materials. If its children have online content then use #1D8235 for both the icon and text (see above).

@tpendragon I honestly don't know what the point of these combined fields is. They don't seem to be used for anything and truncating the json doesn't beak the display.
One solution is to change the type of the field to text
, but again, I can't tell how these combined fields are used.
I think they're used for the headings display, added in this PR: https://github.com/pulibrary/pulfalight/pull/1134/files

I have a #reduce
that's leading to "(deterministic) timeout" and I'm wondering what I can do to find out what's taking so long. Can I #reduce
step-by-step?
Unfortunately no. #reduce
is not really intended for serious use
It turns out that unfolding a proof down to axioms is actually kind of expensive :)
Hmm, well it's also breaking my examples/tests, since it can't even prove things by rfl
at very small input sizes, and I can't figure out why, because the code seems fairly straightforward.
this is also not unusual
I think theorem nat.prime 5 := dec_trivial
times out
it depends on what numerical functions you are calling
I guess it would be nice to have bytecode-based tests for quick dumb sanity checks
You should use #eval
for that
I do, I just wish I could write something that asserts on the result rather than simply printing it
you can use run_cmd
:
run_cmd guard (2 + 2 = 4) run_cmd guard (2 + 2 = 5) -- failed
Perfect, thanks!

Adding Live Templates to a Plugin
This tutorial illustrates how to add default Custom Live Templates to an IntelliJ Platform plugin, and assign valid contexts for these templates based on the surrounding code and file type. In addition, the tutorial discusses how to export existing Live Templates, and bundle them within a plugin. Any Live Template that can be created and exported can be added to a plugin by following the Template Creation, Export, and Extension Point Registration processes.
This tutorial uses the SDK code sample live_templates
.
- Template Creation
- Export the Live Template
- Implement TemplateContextType
- Completing the Live Template Implementation
- Check Plugin
Template Creation
Get started by creating a new Live Template within the IntelliJ Platform-based IDE:
- Add a new Template Group, “Markdown” and create a new Live Template under this group.
- Assign the template the abbreviation “{”.
- Assign the description “SDK: New link reference”.
- Paste the following snippet into the Template text field:
[$TEXT$]($LINK$)$END$
The variables $TEXT$
and $LINK$
may be further configured in the Edit variables dialogue to reorder their precedence and bind to functions that invoke auto-completion at the appropriate time.
In the Edit variables dialog, set the Expression
for the LINK
to complete()
using the combobox.
There are many other predefined functions that developers should become familiar with before implementing any unique functionality in a plugin.
Export the Live Template
Once the Live Template produces the expected result, export the Live Template.
The export produces a file called Markdown.xml
with the following contents:
<templateSet group="Markdown">
<template name="{"
value="[$TEXT$]($LINK$)$END$"
description="SDK: New link reference"
toReformat="false"
toShortenFQNames="false">
<variable name="TEXT" expression="" defaultValue="" alwaysStopAt="true" />
<variable name="LINK" expression="complete()" defaultValue="" alwaysStopAt="true" />
</template>
</templateSet>
Copy this file into the plugin’s resources folder.
Implement TemplateContextType
A TemplateContextType
tells the IntelliJ Platform where the Live Template is applicable: Markdown files.
Every context must have a unique TemplateContextType
defined for it, and many context types are defined by the Platform.
The MarkdownContext
class defines it for Markdown files.
Ultimately, a file’s extension determines the applicable Markdown context.
// Copyright 2000-2020 JetBrains s.r.o. and other contributors. Use of this source code is governed by the Apache 2.0 license that can be found in the LICENSE file.
package org.intellij.sdk.liveTemplates;
import com.intellij.codeInsight.template.TemplateContextType;
import com.intellij.psi.PsiFile;
import org.jetbrains.annotations.NotNull;
public class MarkdownContext extends TemplateContextType {
protected MarkdownContext() {
super("MARKDOWN", "Markdown");
}
@Override
public boolean isInContext(@NotNull PsiFile file, int offset) {
return file.getName().endsWith(".md");
}
}
Within the <template>...</template>
elements in the Markdown.xml
Live Template definition file, add the following context elements:
<variable.../>
<context>
<option name="MARKDOWN" value="true"/>
</context>
</template>
It is not always necessary to define your own TemplateContextType
, as there are many existing template contexts already defined in the IntelliJ Platform.
Consider reusing one of the many existing template context types that inherit from TemplateContextType
if you are augmenting language support to an existing area.
Completing the Live Template Implementation
Depending on the version of the IntelliJ Platform, different steps are used to complete the implementation of the feature.
Versions 2020.1 and Later
For 2020.1 and later, follow this section to register the extension points and then proceed to the Check Plugin section.
Register Extension Points
Using the com.intellij.defaultLiveTemplates
and com.intellij.liveTemplateContext
extension points, register the implementations with the IntelliJ Platform.
The file
attribute in the defaultLiveTemplates
element specifies path/filename
under the src/main/resources
folder.
<extensions defaultExtensionNs="com.intellij">
<defaultLiveTemplates file="/liveTemplates/Markdown.xml"/>
<liveTemplateContext implementation="org.intellij.sdk.liveTemplates.MarkdownContext"/>
</extensions>
Now go to the Check Plugin section to test the template.
Versions 2019.3 and Earlier
For older versions of the IntelliJ Platform follow this section to complete the implementation and register the extension points. Then proceed to the Check Plugin section.
Implement DefaultLiveTemplatesProvider
The MarkdownTemplateProvider
tells the Platform where to find the Live Template settings file.
Make sure to include the full path to the file, relative to the src/main/resources
directory, excluding the file extension.
package org.intellij.sdk.liveTemplates;
import com.intellij.codeInsight.template.impl.DefaultLiveTemplatesProvider;
import org.jetbrains.annotations.Nullable;
public class MarkdownTemplateProvider implements DefaultLiveTemplatesProvider {
@Override
public String[] getDefaultLiveTemplateFiles() {
return new String[]{"liveTemplates/Markdown"};
}
@Nullable
@Override
public String[] getHiddenLiveTemplateFiles() {
return null;
}
}
Register Extension Points
Using the com.intellij.defaultLiveTemplatesProvider
and com.intellij.liveTemplateContext
extension points, register the implementations with the IntelliJ Platform.
<extensions defaultExtensionNs="com.intellij">
<defaultLiveTemplatesProvider implementation="org.intellij.sdk.liveTemplates.MarkdownTemplateProvider"/>
<liveTemplateContext implementation="org.intellij.sdk.liveTemplates.MarkdownContext"/>
</extensions>
Check Plugin
Now verify the plugin is working correctly.
Run the plugin in a Development Instance and verify there is a new entry under Settings/Preferenes | Live Templates | Markdown | { (SDK: New link reference).
Finally, create a new file Test.md
and confirm that the Live Template works by entering a { character and then pressing Tab.

Detailed Description
The QDesktopWidget class provides access to screen information on multi-head systems.
Systems with more than one graphics card and monitor can manage the physical screen space available either as multiple desktops, or as a large virtual desktop.
This class provides information about the user's desktop, such as its total size, number of screens, the geometry of each screen, and whether they are configured as separate desktops or a single virtual desktop.
Widgets provided by Qt use this class to place tooltips, menus and dialog boxes on the correct screen for their parent or application widgets. Applications can use this class to obtain information that can be used to save window positions, or to place child widgets and dialogs on one particular screen.
Obtaining a Desktop Widget
The QApplication::desktop() function is used to get an instance of QDesktopWidget.
The widget's screenGeometry() function provides information about the geometry of the available screens with. The number of screens available is returned by screenCount, and the screenCountChanged() signal is emitted when screens are added or removed. The screen number that a particular point or widget is located in is returned by screenNumber().
Screen Geometry
To obtain the dimensions of a particular screen, call the screenGeometry() function. On some desktop environments, not all of the screen is available for applications to use; for example, an application dock or menu bar may take up some space. Use the availableGeometry() function to obtain the available area for applications.
QDesktopWidget also inherits the QWidget properties, width() and height(), which specify the size of the desktop. However, for desktops with multiple screens, the size of the desktop is the union of all the screen sizes, so width() and height() should not be used for computing the size of a widget to be placed on one of the screens.
On systems that are configured to use the available screens as a single, large virtual desktop, the virtualDesktop property will be set to true. In this case, the widget's size is usually the size of the bounding rectangle of all the screens.
Use of the Primary Screen
For an application, the screen where the main widget resides is the primary screen. This is stored in the primaryScreen property. All windows opened in the context of the application should be constrained to the boundaries of the primary screen; for example, it would be inconvenient if a dialog box popped up on a different screen, or split over two screens.
In the illustration above, Application One's primary screen is screen 0, and App Two's primary screen is screen 1.
See also QApplication and QApplication::desktop().
Property Documentation
primaryScreen : const int
This property holds the index of the screen that is configured to be the primary screen on the system.
Access functions:
| int | primaryScreen() const |
Notifier signal:
| void | primaryScreenChanged() |
screenCount : const int
This property holds the number of screens currently available on the system.
This property was introduced in Qt 4.6.
Access functions:
| int | screenCount() const |
Notifier signal:
| void | screenCountChanged(int newCount) |
virtualDesktop : const bool
if the system manages the available screens in a virtual desktop.
For virtual desktops, screen() will always return the same widget. The size of the virtual desktop is the size of this desktop widget.
Access functions:
| bool | isVirtualDesktop() const |
Member Function Documentation
const QRect QDesktopWidget::availableGeometry(int screen = -1) const
Returns the available geometry of the screen with index screen. What is available will be subrect of screenGeometry() based on what the platform decides is available (for example excludes the dock and menu bar on macOS, or the task bar on Windows). The default screen is used if screen is -1.
See also screenNumber() and screenGeometry().
const QRect QDesktopWidget::availableGeometry(const QWidget *widget) const
This is an overloaded function.
Returns the available geometry of the screen which contains widget.
See also screenGeometry().
const QRect QDesktopWidget::availableGeometry(const QPoint &p) const
This is an overloaded function.
Returns the available geometry of the screen which contains p.
See also screenGeometry().
[signal]
void QDesktopWidget::primaryScreenChanged()
This signal is emitted whenever the primary screen changes.
Note: This doesn't mean the QDesktopWidget::primaryScreen index will necessarily be different, but now it will refer to the new primary screen.
This function was introduced in Qt 5.6.
Note: Notifier signal for property primaryScreen.
See also primaryScreen and screenGeometry().
[virtual protected]
void QDesktopWidget::resizeEvent(QResizeEvent *event)
Reimplemented from QWidget::resizeEvent().
[signal]
void QDesktopWidget::resized(int screen)
This signal is emitted when the size of screen changes.
QWidget *QDesktopWidget::screen(int screen = -1)
Returns a widget that represents the screen with index screen (a value of -1 means the default screen).
If the system uses a virtual desktop, the returned widget will have the geometry of the entire virtual desktop; i.e., bounding every screen.
See also primaryScreen, screenCount, and virtualDesktop.
[signal]
void QDesktopWidget::screenCountChanged(int newCount)
This signal is emitted when the number of screens changes to newCount.
This function was introduced in Qt 4.6.
Note: Notifier signal for property screenCount.
See also screenCount.
const QRect QDesktopWidget::screenGeometry(int screen = -1) const
Returns the geometry of the screen with index screen. The default screen is used if screen is -1.
See also screenNumber().
const QRect QDesktopWidget::screenGeometry(const QWidget *widget) const
This is an overloaded function.
Returns the geometry of the screen which contains widget.
const QRect QDesktopWidget::screenGeometry(const QPoint &p) const
This is an overloaded function.
Returns the geometry of the screen which contains p.
int QDesktopWidget::screenNumber(const QWidget *widget = Q_NULLPTR) const
Returns the index of the screen that contains the largest part of widget, or -1 if the widget not on a screen.
See also primaryScreen.
int QDesktopWidget::screenNumber(const QPoint &point) const
This is an overloaded function.
Returns the index of the screen that contains the point, or the screen which is the shortest distance from the point.
See also primaryScreen.
[signal]
void QDesktopWidget::workAreaResized(int screen)
This signal is emitted when the work area available on screen changes.

In jQuery Mobile, form submissions are automatically handled using Ajax whenever possible, creating a smooth transition between the form and the result page. To ensure your form submits as intended, be sure to specify action
and method
properties on your form element. When unspecified, the method will default to get
, and the action
will default to the current page's relative path (found via $.mobile.path.get()
)
Forms also accept attributes for transitions just like anchors, such as data-transition="pop"
and data-direction="reverse"
. To submit a form without Ajax, you can either disable Ajax form handling globally, or per form via the data-ajax="false"
attribute. The target
attribute (as in target="_blank"
) is respected on forms as well, and will default to the browser's handling of that target when the form submits. Note that unlike anchors, the rel
attribute is not allowed on forms.
This demonstrates automated ajax handling of form submissions. The form below is configured to send a GET
request to forms-sample-response.php
. On submit, jQuery Mobile will make sure that the Url specified is able to be retrieved via Ajax, and handle it appropriately. Keep in mind that just like ordinary HTTP form submissions, jQuery Mobile allows GET
result pages to be bookmarked by updating the URL hash when the response returns successfully. Also like ordinary form submissions, POST
requests do not contain query parameters in the hash, so they are not bookmarkable.
To prevent form submissions from being automatically handled with Ajax, add the data-ajax="false"
attribute to the form element. You can also turn off Ajax form handling completely via the ajaxEnabled
global config option.
The form below is identical to the one above except for the addition of the data-ajax="false"
attribute. When the submit button is pressed, it will result in a full page refresh.
You can submit forms to the same URL you're currently viewing by setting the form's action
attribute to that URL. This page demonstrates.
When a POST
request is submitted to a page that's already in the DOM (which would commonly happen when submitting a form to the same URL currently in view), the response URL will be identical to that existing page, as POST
requests do not append query string parameters to the URL. In this situation, jQuery Mobile will replace the page that submitted the form with the page returned in the response body.

RDN implements a Relational Dependency Network
J. Neville and D. Jensen. Relational dependency networks.
Journal of Machine Learning Research, 8, 2007.
RDNs are a relational extension to dependency networks. Dependency networks are
collections of conditional probability distributions learned independently from
data. If the data are large enough then the combination of the CPDs specifies
a coherent joint distribution.
Functionality is provided through extendable modules. Please see rdn.modules
package for more details. The ListenerModules allow operations to run at specific
iterations in the Gibbs chain. This can be used for updating the database, saving
a sample from the joint distribution, updating a posterior distribution, or
logging progress. See rdn.modules.listeners for some useful defaults.
