Introduction to the \(p\)-adics#
This tutorial outlines what you need to know in order to use \(p\)-adics in Sage effectively.
Our goal is to create a rich structure of different options that will reflect the mathematical structures of the \(p\)-adics. This is very much a work in progress: some of the classes that we eventually intend to include have not yet been written, and some of the functionality for classes in existence has not yet been implemented. In addition, while we strive for perfect code, bugs (both subtle and not-so-subtle) continue to evade our clutches. As a user, you serve an important role. By writing non-trivial code that uses the \(p\)-adics, you both give us insight into what features are actually used and also expose problems in the code for us to fix.
Our design philosophy has been to create a robust, usable interface working first, with simple-minded implementations underneath. We want this interface to stabilize rapidly, so that users’ code does not have to change. Once we get the framework in place, we can go back and work on the algorithms and implementations underneath. All of the current \(p\)-adic code is currently written in pure Python, which means that it does not have the speed advantage of compiled code. Thus our \(p\)-adics can be painfully slow at times when you’re doing real computations. However, finding and fixing bugs in Python code is far easier than finding and fixing errors in the compiled alternative within Sage (Cython), and Python code is also faster and easier to write. We thus have significantly more functionality implemented and working than we would have if we had chosen to focus initially on speed. And at some point in the future, we will go back and improve the speed. Any code you have written on top of our \(p\)-adics will then get an immediate performance enhancement.
If you do find bugs, have feature requests or general comments, please email<EMAIL_ADDRESS>or<EMAIL_ADDRESS>Terminology and types of \(p\)-adics#
To write down a general \(p\)-adic element completely would require an infinite amount of data. Since computers do not have infinite storage space, we must instead store finite approximations to elements. Thus, just as in the case of floating point numbers for representing reals, we have to store an element to a finite precision level. The different ways of doing this account for the different types of \(p\)-adics.
We can think of \(p\)-adics in two ways. First, as a projective limit of finite groups:
Secondly, as Cauchy sequences of rationals (or integers, in the case of \(\ZZ_p\)) under the \(p\)-adic metric. Since we only need to consider these sequences up to equivalence, this second way of thinking of the \(p\)-adics is the same as considering power series in \(p\) with integral coefficients in the range \(0\) to \(p-1\). If we only allow nonnegative powers of \(p\) then these power series converge to elements of \(\ZZ_p\), and if we allow bounded negative powers of \(p\) then we get \(\QQ_p\).
Both of these representations give a natural way of thinking about finite approximations to a \(p\)-adic element. In the first representation, we can just stop at some point in the projective limit, giving an element of \(\ZZ/p^n\ZZ\). As \(\ZZ_p / p^n\ZZ_p \cong \ZZ/p^n\ZZ\), this is equivalent to specifying our element modulo \(p^n\ZZ_p\).
The absolute precision of a finite approximation \(\bar{x} \in \ZZ/p^n\ZZ\) to \(x \in \ZZ_p\) is the non-negative integer \(n\).
In the second representation, we can achieve the same thing by truncating a series
at \(p^n\), yielding
As above, we call this \(n\) the absolute precision of our element.
Given any \(x \in \QQ_p\) with \(x \ne 0\), we can write \(x = p^v u\) where \(v \in \ZZ\) and \(u \in \ZZ_p^{\times}\). We could thus also store an element of \(\QQ_p\) (or \(\ZZ_p\)) by storing \(v\) and a finite approximation of \(u\). This motivates the following definition: the relative precision of an approximation to \(x\) is defined as the absolute precision of the approximation minus the valuation of \(x\). For example, if \(x = a_k p^k + a_{k+1} p^{k+1} + \cdots + a_{n-1} p^{n-1} + O(p^n)\) then the absolute precision of \(x\) is \(n\), the valuation of \(x\) is \(k\) and the relative precision of \(x\) is \(n-k\).
There are three different representations of \(\ZZ_p\) in Sage and one representation of \(\QQ_p\):
the fixed modulus ring
the capped absolute precision ring
the capped relative precision ring, and
the capped relative precision field.
Fixed Modulus Rings#
The first, and simplest, type of \(\ZZ_p\) is basically a wrapper around \(\ZZ/p^n\ZZ\), providing a unified interface with the rest of the \(p\)-adics. You specify a precision, and all elements are stored to that absolute precision. If you perform an operation that would normally lose precision, the element does not track that it no longer has full precision.
The fixed modulus ring provides the lowest level of convenience, but it is also the one that has the lowest computational overhead. Once we have ironed out some bugs, the fixed modulus elements will be those most optimized for speed.
As with all of the implementations of \(\ZZ_p\), one
creates a new ring using the constructor Zp
, and passing in
'fixed-mod'
for the type
parameter. For example,
sage: R = Zp(5, prec = 10, type = 'fixed-mod', print_mode = 'series')
sage: R
5-adic Ring of fixed modulus 5^10
One can create elements as follows:
sage: a = R(375)
sage: a
3*5^3
sage: b = R(105)
sage: b
5 + 4*5^2
Now that we have some elements, we can do arithmetic in the ring.
sage: a + b
5 + 4*5^2 + 3*5^3
sage: a * b
3*5^4 + 2*5^5 + 2*5^6
Floor division (//) divides even though the result isn’t really known to the claimed precision; note that division isn’t defined:
sage: a // 5
3*5^2
sage: a / 5
Traceback (most recent call last):
...
ValueError: cannot invert non-unit
Since elements don’t actually store their actual precision, one can only divide by units:
sage: a / 2
4*5^3 + 2*5^4 + 2*5^5 + 2*5^6 + 2*5^7 + 2*5^8 + 2*5^9
sage: a / b
Traceback (most recent call last):
...
ValueError: cannot invert non-unit
If you want to divide by a non-unit, do it using the //
operator:
sage: a // b
3*5^2 + 3*5^3 + 2*5^5 + 5^6 + 4*5^7 + 2*5^8 + 3*5^9
Capped Absolute Rings#
The second type of implementation of \(\ZZ_p\) is similar to the fixed modulus implementation, except that individual elements track their known precision. The absolute precision of each element is limited to be less than the precision cap of the ring, even if mathematically the precision of the element would be known to greater precision (see Appendix A for the reasons for the existence of a precision cap).
Once again, use Zp
to create a capped absolute \(p\)-adic
ring.
sage: R = Zp(5, prec = 10, type = 'capped-abs', print_mode = 'series')
sage: R
5-adic Ring with capped absolute precision 10
We can do similar things as in the fixed modulus case:
sage: a = R(375)
sage: a
3*5^3 + O(5^10)
sage: b = R(105)
sage: b
5 + 4*5^2 + O(5^10)
sage: a + b
5 + 4*5^2 + 3*5^3 + O(5^10)
sage: a * b
3*5^4 + 2*5^5 + 2*5^6 + O(5^10)
sage: c = a // 5
sage: c
3*5^2 + O(5^9)
Note that when we divided by 5, the precision of c
dropped.
This lower precision is now reflected in arithmetic.
sage: c + b
5 + 2*5^2 + 5^3 + O(5^9)
Division is allowed: the element that results is a capped relative field element, which is discussed in the next section:
sage: 1 / (c + b)
5^-1 + 3 + 2*5 + 5^2 + 4*5^3 + 4*5^4 + 3*5^6 + O(5^7)
Capped Relative Rings and Fields#
Instead of restricting the absolute precision of elements (which doesn’t make much sense when elements have negative valuations), one can cap the relative precision of elements. This is analogous to floating point representations of real numbers. As in the reals, multiplication works very well: the valuations add and the relative precision of the product is the minimum of the relative precisions of the inputs. Addition, however, faces similar issues as floating point addition: relative precision is lost when lower order terms cancel.
To create a capped relative precision ring, use Zp
as before.
To create capped relative precision fields, use Qp
.
sage: R = Zp(5, prec = 10, type = 'capped-rel', print_mode = 'series')
sage: R
5-adic Ring with capped relative precision 10
sage: K = Qp(5, prec = 10, type = 'capped-rel', print_mode = 'series')
sage: K
5-adic Field with capped relative precision 10
We can do all of the same operations as in the other two cases, but precision works a bit differently: the maximum precision of an element is limited by the precision cap of the ring.
sage: a = R(375)
sage: a
3*5^3 + O(5^13)
sage: b = K(105)
sage: b
5 + 4*5^2 + O(5^11)
sage: a + b
5 + 4*5^2 + 3*5^3 + O(5^11)
sage: a * b
3*5^4 + 2*5^5 + 2*5^6 + O(5^14)
sage: c = a // 5
sage: c
3*5^2 + O(5^12)
sage: c + 1
1 + 3*5^2 + O(5^10)
As with the capped absolute precision rings, we can divide, yielding a capped relative precision field element.
sage: 1 / (c + b)
5^-1 + 3 + 2*5 + 5^2 + 4*5^3 + 4*5^4 + 3*5^6 + 2*5^7 + 5^8 + O(5^9)
Unramified Extensions#
One can create unramified extensions of \(\ZZ_p\) and
\(\QQ_p\) using the functions Zq
and Qq
.
In addition to requiring a prime power as the first argument,
Zq
also requires a name for the generator of the residue field.
One can specify this name as follows:
sage: R.<c> = Zq(125, prec = 20); R
5-adic Unramified Extension Ring in c defined by x^3 + 3*x + 3
Eisenstein Extensions#
It is also possible to create Eisenstein extensions of \(\ZZ_p\) and \(\QQ_p\). In order to do so, create the ground field first:
sage: R = Zp(5, 2)
Then define the polynomial yielding the desired extension.:
sage: S.<x> = ZZ[]
sage: f = x^5 - 25*x^3 + 15*x - 5
Finally, use the ext
function on the ground field to create the
desired extension.:
sage: W.<w> = R.ext(f)
You can do arithmetic in this Eisenstein extension:
sage: (1 + w)^7
1 + 2*w + w^2 + w^5 + 3*w^6 + 3*w^7 + 3*w^8 + w^9 + O(w^10)
Note that the precision cap increased by a factor of 5, since the ramification index of this extension over \(\ZZ_p\) is 5.

New Jersey woman gets 6 years in fatal stabbing of identical twin
by Louis CasianoA New Jersey woman convicted of fatally stabbing her identical twin sister was sentenced to six years in prison on Thursday.
Amanda Ramirez pleaded guilty in September to manslaughter in the June 22 death of her sister, Anna.
She initially denied being involved in the stabbing but then claimed she acted in self-defense when her sister came at her with a knife in their Camden apartment.
Anna Ramirez was pronounced dead less than an hour later.

Betis will have to sell to sign in the winter
by BeSoccerReal Betis will have to sell players to be able to sign people in January. It is getting closer until the window opens and the board will have to decide soon what the plan is if they want to make transfers.
The situation at the Benito Villamarin is not how they thought it would be at the beginning of the season. The team are fighting to avoid the relegation zone and initially, their plan was to finish in the top half.
Some people are pointing the blame at the coach, but also at the players. An improvement of the squad may be carried out and they can do that in the January transfer window. There are footballers in the market and they might make some signings.
Featured links

- Possible 'Clasico' in the Spanish Supercup final
- Who has the most free-kicks goals: Messi or Cristiano?
However, according to 'Estadio Deportivo', the club will first have to sell people before buying players. That way they will balance the books before signing new footballers. That could be key in order to move out of trouble and up the table.
The previously cited source says that Sanabria, on loan from Genoa, is the main candidate to leave. He joined Betis from Roma a while back and has still not managed to perform in Seville.


They do not call themselves ‘artists’, but their creations mesmerize and challenge passers-by. They are shun by traditional auction houses and most museums, but might be the future of art. We met the new-media art scene in Belgrade last week, at the Resonate festival.
Belgrade has been announced to us as the new Berlin. Serbia was hit hard by the financial crisis. That’s the first thing locals mention. Berlin’s flamboyant mayor Klaus Wowereit is notoriously close to his city’s cultural class. Dragan Đilas, Belgrade’s mayor until late 2013, is a mass media mogul, who has brought Big Brother to Serbia. Performance artist Marina Abramović, who exposed at the New-York Guggenheim and works with Lady Gaga, is from Belgrade. The Museum of Contemporary Arts collection holds works by Salvador Dalí, Andy Warhol, George Maciunas and Hannah Wilke. When it opened in 1958 it was one of Europe’s first national museums of modern art. Since it closed for renovation works in 2007 it has been slowly transforming into a ruin. Government funding has run out.
Belgrade is setting out to fulfill the “poor, but sexy” promise, that Wowereit famously made about Berlin a decade ago. A young generation of artists is bringing the city to the center stage of the art scene. Its cheap rents are turning it into a safe haven for creative types. In cost of living surveys Belgrade regularly ranks far better than Berlin or other cities famous for their bohemian scenes such as Portland or Istanbul.
Concept stores, galleries, coworking spaces and creative agencies are popping up all over the old centre along the banks of the Sava River and towards the Danube. Artists, tinkerers and hackers are at the forefront of this development. Milos Rancic, the founder of Hacklab Belgrade on the borders of the city centre, thinks young Serbs’ taste for computer code goes back to inventor and futurist Nikola Tesla. Rancic has been working on free software projects for over a decade. “People aspire to be as inventive with electronics as Tesla”, he says as he takes a sip of his energy drink and lights another Davidoff cigarette.
Around Studentski Square in the centre of Belgrade, the Resonate festival, organized by Maria Jelesijević, a Belgrade-based visual artist, and Filip Visnjic, an architect living in London, is bringing together code artists from 184 cities. It's an intimate crowd of only 500 participants. The tickets of have been sold out for months.


The personification of all the dreams and the dreamers. Kind of a downer to beat her, actually. She can change laws at whim, and deal pretty big damage to multiple units. Other than that, she isn't much of a challenge.
The true form of Emperor Palamecia. Her soul is good, but lives in Hell.
A large hydra fought in the coliseum.
The boss in the final mission, with a raft of incredible attacks. She also appears in the ending as the "goddess of the planet".
The final boss of FF9 is more symbolic than relevant to the storyline (See FF9 Characters. Its signature attack Grand Cross (used also by FF5's final boss) causes many status ailments and lots of damage. Once you figure out how to defeat it, the fight's over pretty quickly.
Also known as "Omega Gold". This optional boss is created at the monster arena, after you've captured ten of every single monster in Spira and beaten every other monster in the Monster Arena. He resembles a palette swap of Ultima Weapon. I personally haven't encountered it yet, but they say he's one mother of a fight!
Exdeath the "tree" uses a very unsettling "Void" attack which just makes one character disappear!  It uses a variety of status problems, physical attacks, magic attacks, defensive spells, and the almighty Almagest spell. Winner of the Most Psychedelic Background award. See also FF5 Characters.
A very bizarre optional boss, whose battle takes place at the Chocobo Air Garden. Ozma is by far the hardest boss of FF9 (far eclipsing Necron). It resembles nothing more than a colorful sphere. It gets to move about three times a round, and consistently cures itself or casts powerful magic (including ones that cause big status problems or kill instantly). What's worse, unless you pursue yet another side quest, you can't use physical attacks against it! When you win you get a useless Strategy Guide and a very useful Pumice and Dark Matter.
This guy just keeps coming back for more, even after he dies! Still, a bit more wimpy than most final bosses. See also FF2 Characters.
This boss is only seen in FF10 International. Lacking that version, I don't know much else about it, but it's apparently even harder than the Dark Aeons.
The final boss of the FF11 "Chains of Promathia" expansion pack. He is the twilight god, on par with Altana. He created the ark angels and the beastmen. He cursed people of Vana'diel for attempting to open the gates of paradise. This curse is the emptiness threatening to consume the land. To complete his purpose, he must be resurrected and killed so that every citizen will return to him when he dies.
Like Emerald Weapon, this special boss was only in FF7 (NA) and the Japanese re-release, FF7 International. It lives under the Corel Desert (once it appears), with only a tiny red arm sticking out, waiting for a curious player to come investigate. It has the ability to eliminate two players from battle, leaving only one, and it cannot be defeated unless its two claws are buried in the sand. If you defeat it, a man in Kalm Town will give you a free Gold Chocobo!

Entering the Uploaded Files list causes the program to query the FreeREG server and refresh the list of files that have previously been uploaded by the logged on User ID. This can, depending on the number of files, take a noticeable amount of time.
When complete, the window will show a list of filenames on the left-hand side and the rest of the window is used to show some details about the selected file. The list is sortable by name, in ascending or descending sequence: just double-click on the column heading. A right-click on the heading also gives access to these sort options, along with some options related to Groups. For this list, the only grouping that makes any real sense when the transcriber has uploaded files for more than one county. In this case selecting to group the files by Batch will actually group them by County.
From a file management point of view, all that can be done with the uploaded files is to either delete them or view their contents. This is indicated by the presnce of the buttons at the bottom of the window. Deleting a file will remove it from the FreeREG database so that locally, it becomes a new file again.
Viewing the contents of a file is the initial step in downloading the file and storing it on the PC. The contents are displayed in a read-only screen that superficially looks like a Notepad window. Pressing the Save Transcription file to PC button will result in a standard Windows dialog to save the file in the default folder.

Instructions For The Sender-Receiver game.
{% endblock %}
{% block content %}
Phase 2: Sender-Receiver Game
This game has two players: a sender and a receiver.
You will play this game twice, once as the sender and once as the receiver. You may play as sender first, or as receiver first.
Each time, both the sender and the receiver will begin
with {{ Constants.endowment }} in their account.
You will be randomly partnered with a different participant each time.
Neither you nor your partners will ever learn the identity of the other.
Playing as the Sender:
As a sender, you must decide how much of your {{ Constants.endowment }} endowment
you want to transfer to the receiver you are matched with.
You may transfer between 0 to {{ Constants.endowment }},
which will be tripled and placed in the receiver’s account.
For example, if you transfer 2 tokens, then 6 tokens will be added to the receiver’s account.
You will have 8 tokens in your account, and the receiver will have 6 tokens in theirs.
Playing as the Receiver:
When playing as the receiver, you must decide how many tokens to transfer back to the sender. Your decision will depend on how many tokens
the sender transferred into your account.

You can transfer from your account, back to the sender,
any amount from 0 up to the total number of tokens in your account.
For example, if the sender transfers 2 tokens,
then the receiver’s account now has 10 + 3 x 2 = 16 tokens.
As the receiver, you can choose to transfer between 0 and 16 tokens back to the sender.
You will keep whatever remains in your account.
Your earnings for this round are the mean of your earnings as sender and receiver.
Example 1:
As the sender, you choose to transfer 3 of your 10 tokens to the
person you are randomly matched with.
The person you are randomly matched with sees in the Receiver Phase
that they were sent 3,
which is multiplied by 3 so that they have 9 tokens in their account.
They choose to transfer 4 back to your account.
At the end of this round, you have 10 – 3 + 4 = 11 tokens.
The receiver you were matched with has 10 + 9 – 4 = 15.
Example 2:
As the receiver you find out that the sender you are randomly matched
with chose to transfer 5 tokens to your account. This 5 was multiplied by 3 so that you have 10 + 3 x 5 = 25
tokens in your account. You choose to transfer 6 back to the sender.
At the end of this round, your private account has 10 + 15 – 6 = 19 tokens.
The sender you were matched with has 10 – 5 + 6 = 11.
Quiz 2:
You will receive 2 tokens for each complete
correct answer to the following questions, paid separately
at the end of the experiment.
Suppose you play as a Sender first, and then as a Receiver.
1. As a Sender, you choose to transfer 6 tokens to the receiver.
The receiver’s account increases by: {{ formfield 'answer_1' }}
The receiver chooses to transfer 8 back to you.
Now, the amount in your account is: {{formfield 'answer_2' }}
The amount in the receiver’s account is: {{formfield 'answer_3' }}
2. As a Receiver, the sender you are matched with transfers 7 tokens to your account.
Your account increases by: {{formfield 'answer_4' }}
You now have in your account: {{formfield 'answer_5' }}
You choose to transfer 11 tokens back to the sender’s account.
The sender now has in their account: {{formfield 'answer_6' }}
You now have in your account: {{formfield 'answer_7' }}
3. At the end of this round, your earnings for this round, which are the average of your earnings as sender and receiver, are: {{formfield 'answer_8' }}.

I'm A Celebrity could face Ofcom investigation over ‘unfair’ live Bushtucker trial
48 viewers complained
by Rebecca CarterOfcom has received complaints from viewers over last night's live I'm A Celebrity Bushtucker trial.
James Haskell, Roman Kemp, Ian Wright, Caitlyn Jenner, Andrew Maxwell, Jacqueline Jossa and Adele Roberts took part in a Love Island themed trial to win a roast dinner for each campmate.
However, one challenge in particular left viewers infuriated as they claimed it was "impossible" for James and Roman to do.
Read more: Ant McPartlin and Dec Donnelly hit back as viewers claim I'm A Celebrity live trial was 'fixed'
The last trial saw James and Roman lying in a bed filled with snakes.
They had to try and unscrew three stars in the blue boxes, which were on James' side and filled with a crab, spiders and cockroaches, and move it to the corresponding yellow box on Roman's side, which were also filled with critters, in just 90 seconds.
The pair didn't manage to complete the trial, meaning Ian, Cliff Parisi and Andy Whyment weren't going to be getting their roasts.
Viewers were fuming and some even claimed the trial was "fixed".
Some were so angry that they complained to watchdog Ofcom about the episode.
A spokesperson confirmed that 48 people complained.
They said: "We are assessing these complaints against our broadcasting rules, before deciding whether or not to investigate."
It comes after hosts Ant McPartlin and Dec Donnelly defended the show after viewers insisted the trial was "unfair".
One person had tweeted: "There was no way anyone on this earth could have completed James & Roman's trial in 90secs! Be fair and feed the last 3 will you #ImACelebrity2019. Shouldn't have had less than 3 mins on that."
The duo replied: "The stand ins did it when we tested it."

Following the trial, James even vented his frustration after Dec asked him: "That was unlucky. What was it James?"
James hit back: "What was it? It was the very fact there was a giant crab in the way that you wanted me to carefully caress in a different direction as I tried to unscrew a star in its face."
Dec exclaimed: "Alright someone's getting prickly!"
I'm A Celebrity continues tonight at 9pm on ITV.
Did you complain to Ofcom about the trial? Leave us a comment on our Facebook page @EntertainmentDailyFix and let us know.


Tonight I fell before the good graces of Lady Salvia, and I feel truly blessed to have received her gracious hospitality. I encountered her one night before, though in a very inappropriate setting, and I felt that I missed much of her insights.
Tonight however, was much different, as I was working with the very potent 10x extract. I was with a special friend who would also partake; we were both sitting comfortably in his darkened room. I loaded my glass bowl (using it for the first time as it was reserved for her) with a very small amount of material, possibly at most a tenth of a gram. I placed the blue flame of my torch light to the alluring dark-green salvia which immediately turned flame red, and then inhaled deeply. Holding this for about 30 seconds I realized there was more left in the bowl, so I took another hit. As I inhaled the cool, agreeable smoke, I was immediately pulled to the floor by a strange indiscernible force. I felt as if I had been sucked out of my body for a few seconds, into a space of complete nothingness. This absolute dissociation soon passed and I gained awareness of my body again.
With my eyes closed, an almost infinite 2-dimensional plane of kaleidoscoping dream visions danced at a dizzying pace. Some of the images were downright funny, though I canít remember why. Perhaps the lady was in especially good spirits, as this state of awareness felt very comfortable, even when I was completely dissociated from my body and could feel her ďpullĒ. The visions were similar to the those induced by a strong psilocybin experience, only they were playing out on a more subconscious level, lacking the intense emotional connections of the mushroom peak. They were organic and familiar images and memories, materializing out of a swirl of geometric iridescence. This was the dreamtime. Hovering in the spatial infinity of my own consciousness, connected to the entire universe.
As my bodily awareness became more apparent, I felt this ďspaceĒ moving against my skin, causing a rain of tingling pins and needles. I could see a tunnel moving out before me, and then some thought triggered what seemed like a drop of water hitting the surface of a puddle, and the ripples undulated throughout my body. This would occur again later in the experience. I remember getting the feeling that the lady was trying to show me something specific, which I obviously must have missed. I could almost hear her voice: ďWhy donít you see where Iím leading you.Ē I remember, almost laughingly replying, ďItís all so beautiful, so amusing, but itís too fast.Ē
Thatís when I saw her hands, like two blooming rose buds, grab each frame and slow the ongoing collage of consciousness down to a more observable rate. By then however it was too late, and the physical realm called me slowly back. I remember sharing these events with my friend, who had embarked as well, and he described having an equally positive and intriguing experience.
I can only say that the lady is an exotic and powerful plant spirit. The space we (and so many others!) accessed shows real promise of serious exploratory potential. I think it may be equally important as the DMTís. Unlike the tryptamines, however, her Sageness prefers the route of dreams, not just sensory experience. I guess that is the best I can explain it. But donít think she isnít direct; the weirdness alone will astound most people. Somehow I perceived the chaotic array of (normally) subconscious imagery as humorous and insightful, though I can see where with the wrong set and setting someone could really become frightened. Especially by the strange gravitational tactile sensations she evokes. I remember having a very brief pornographic moment as well, and somehow I think, even in my disembodied state, I blushed. Now howís that for weird?

At this point, you've created the initial implementation of the StockWatcher application, simulating stock data in the client-side code.
In this section, you'll make a GWT remote procedure call to a server-side method which returns the stock data. The server-side code that gets invoked from the client is also known as a service; the act of making a remote procedure call is referred to as invoking a service.
You'll learn to:
This tutorial builds on the GWT concepts and the StockWatcher application created in the Getting Started tutorial. If you have not completed the Getting Started tutorial and are familiar with basic GWT concepts, you can import the StockWatcher project as coded to this point.
File
menu, select the Import...
menu option.Next
button.Finish
button.
If you are using ant, edit the gwt.sdk
property in StockWatcher/build.xml to point to where you unzipped GWT.
The GWT RPC framework makes it easy for the client and server components of your web application to exchange Java objects over HTTP. The server-side code that gets invoked from the client is often referred to as a service. The implementation of a GWT RPC service is based on the well-known Java servlet architecture. Within the client code, you'll use an automatically-generated proxy class to make calls to the service. GWT will handle serialization of the Java objects passing back and forth—the arguments in the method calls and the return value.
Important: GWT RPC services are not the same as web services based on SOAP or REST. They are simply as a lightweight method for transferring data between your server and the GWT application on the client. To compare single and multi-tier deployment options for integrating GWT RPC services into your application, see the Developer's Guide, Architectural Perspectives.
When setting up GWT RPC, you will focus on these three elements involved in calling procedures running on remote servers.
In order to define your RPC interface, you need to write three components:
A service implementation must extend RemoteServiceServlet and must implement the associated service interface. Notice that the service implementation does not implement the asynchronous version of the service interface. Every service implementation is ultimately a servlet, but rather than extending HttpServlet, it extends RemoteServiceServlet instead. RemoteServiceServlet automatically handles serialization of the data being passed between the client and the server and invoking the intended method in your service implementation.
In this tutorial, you are going to take the functionality in the refreshWatchList method and move it from the client to the server. Currently you pass the refreshWatchList method an array of stock symbols and it returns the corresponding stock data. It then calls the updateTable method to populate the FlexTable with the stock data.
/** * Generate random stock prices. */ private void refreshWatchList() { final double MAX_PRICE = 100.0; // $100.00 final double MAX_PRICE_CHANGE = 0.02; // +/- 2% StockPrice[] prices = new StockPrice[stocks.size()]; for (int i = 0; i < stocks.size(); i++) { double price = Random.nextDouble() * MAX_PRICE; double change = price * MAX_PRICE_CHANGE * (Random.nextDouble() * 2.0 - 1.0); prices[i] = new StockPrice(stocks.get(i), price, change); } updateTable(prices); }
To create the service, you will:
In GWT, an RPC service is defined by an interface that extends the GWT RemoteService interface. For the StockPriceService interface, you need to define only one method: a method that will accept an array of stock symbols and return the data associated with each stock as an array of StockPrice objects.
com.google.gwt.sample.stockwatcher.client
File > New > Interface
StockPriceService
Finish
package com.google.gwt.sample.stockwatcher.client; import com.google.gwt.user.client.rpc.RemoteService; import com.google.gwt.user.client.rpc.RemoteServiceRelativePath; @RemoteServiceRelativePath("stockPrices") public interface StockPriceService extends RemoteService { StockPrice[] getPrices(String[] symbols); }
Now create the class (StockPriceServiceImpl) that lives on the server. As defined in the interface, StockPriceServiceImpl will contain only one method, the method that returns the stock price data.
To do this, implement the service interface by creating a class that also extends the GWT RemoteServiceServlet class. RemoteServiceServlet does the work of deserializing incoming requests from the client and serializing outgoing responses.
The service implementation runs on the server as Java bytecode; it's not translated into JavaScript. Therefore, the service implementation does not have the same language constraints as the client-side code. To keep the code for the client separate from the code for the server, you'll put it in a separate package (com.google.gwt.sample.stockwatcher.server).
.client
to .server
StockPriceServiceImpl
com.google.gwt.user.server.rpc.RemoteServiceServlet
com.google.gwt.sample.stockwatcher.client.StockPriceService

The embedded servlet container (Jetty) can host the servlets that contain your service implementation. This means you can take advantage of running your application in development mode while testing and debugging the server-side Java code.
To set this up, add <servlet> and <servlet-mapping> elements to the web application deployment descriptor (web.xml) and point to the implementation class (StockPriceServiceImpl).
Starting with GWT 1.6, servlets should be defined in the web application deployment descriptor (web.xml) instead of the GWT module (StockWatcher.gwt.xml).
In the <servlet-mapping> element, the url-pattern can be in the form of an absolute directory path (for example, /spellcheck
or /common/login
).
If you specify a default service path with a @RemoteServiceRelativePath annotation on the service interface (as you did with StockPriceService), then make sure the url-pattern matches the annotation value.
Because you've mapped the StockPriceService to "stockPrices" and the module rename-to attribute in StockWatcher.gwt.xml is "stockwatcher", the full URL will be:
http://localhost:8888/stockwatcher/stockPrices

You need to to add an AsyncCallback parameter to all your service methods.
To add an AsyncCallback parameter to all of our service methods, you must define a new interface as follows:
package com.google.gwt.sample.stockwatcher.client; import com.google.gwt.user.client.rpc.AsyncCallback; public interface StockPriceServiceAsync { void getPrices(String[] symbols, AsyncCallback<StockPrice[]> callback); }
Tip: The Google Plugin for Eclipse will generate an error when it finds a synchronous remote service without a matching asynchronous interface. You can right click on the error in Eclipse, select Quick Fix, and choose the "Create asynchronous RemoteService interface" option to automatically generate the asynchronous interface.
When you call a remote procedure, you specify a callback method which executes when the call completes. You specify the callback method by passing an AsyncCallback object to the service proxy class. The AsyncCallback object contains two methods, one of which is called depending on whether the call failed or succeeded: onFailure(Throwable) and onSuccess(T).
private ArrayList<String> stocks = new ArrayList<String>();
private StockPriceServiceAsync stockPriceSvc = GWT.create(StockPriceService.class);
private void refreshWatchList() {
// Initialize the service proxy.
if (stockPriceSvc == null) {
stockPriceSvc = GWT.create(StockPriceService.class);
}
// Set up the callback object.
AsyncCallback<StockPrice[]> callback = new AsyncCallback<StockPrice[]>() {
public void onFailure(Throwable caught) {
// TODO: Do something with errors.
}
public void onSuccess(StockPrice[] result) {
updateTable(result);
}
};
// Make the call to the stock price service.
stockPriceSvc.getPrices(stocks.toArray(new String[0]), callback);
}
import com.google.gwt.core.client.GWT; import com.google.gwt.user.client.rpc.AsyncCallback;
At this point, you've created a service and pointed to it in the module XML file, set up the mechanism for making asynchronous calls, and generated a service proxy on the client side to call the service. However there's a problem.
[ERROR] Type 'com.google.gwt.sample.stockwatcher.client.StockPrice' was not serializable
and has no concrete serializable subtypes
In the service implementation (StockPriceServiceImpl), you inherited the code that serializes and deserializes Java objects by extending the RemoteServiceServlet class. However the problem is that we did not also edit the StockPrice class to indicate it was serializable.
Serialization is the process of packaging the contents of an object so that it can moved from one application to another application or stored for later use. Anytime you transfer an object over the network via GWT RPC, it must be serialized. Specifically, GWT RPC requires that all service method parameters and return types be serializable.
A type is serializable and can be used in a service interface if one of the following is true:
GWT honors the transient keyword, so values in those fields are not serialized (and thus, not sent over the wire when used in RPC calls).
Note: GWT serialization is not the same as serialization based on the Java Serializable interface.
For more information on what is and is not serializable in GWT, see the Developer's Guide, Serializable Types.
Based on the requirements for serialization, what do you need to do to make the StockPrice class ready for GWT RPC? Because all its instance fields are primitive types, all you need to do in this case is implement the Serializable or IsSerializable interface.
package com.google.gwt.sample.stockwatcher.client; import java.io.Serializable; public class StockPrice implements Serializable { private String symbol; private double price; private double change; ...
At this point, the basic RPC mechanism is working. However, there is one TODO left. You need to code the error handling in case the callback fails.
When a remote procedure call fails, the cause falls into one of two categories: an unexpected exception or a checked exception. In either case you want to handle the exception and, if necessary, provide feedback to the user.
Unexpected exceptions: Any number of unexpected occurrences could cause the call to a remote procedure to fail: the network could be down; the HTTP server on the other end might not be listening; the DNS server could be on fire, and so forth.
Another type of unexpected exception can occur if GWT is able to invoke the service method, but the service implementation throws an undeclared exception. For example, a bug may cause a NullPointerException.
When unexpected exceptions occur in the service implementation, you can find the full stack trace in the development mode log. On the client-side, the onFailure(Throwable) callback method will receive an InvocationException with the generic message: The call failed on the server; see server log for details.
Checked exceptions: If you know a service method might throw a particular type of exception and you want the client-side code to be able to handle it, you can use checked exceptions. GWT supports the throws keyword so you can add it to your service interface methods as needed. When checked exceptions occur in an RPC service method, GWT will serialize the exception and send it back to the caller on the client for handling.
To learn how to handle errors in RPC, you will throw an error when the user adds a stock code which you've defined as "delisted"—causing the call to fail. Then you'll handle the failure by displaying an error message to the user.
DelistedException
Finish
package com.google.gwt.sample.stockwatcher.client; import java.io.Serializable; public class DelistedException extends Exception implements Serializable { private String symbol; public DelistedException() { } public DelistedException(String symbol) { this.symbol = symbol; } public String getSymbol() { return this.symbol; } }
package com.google.gwt.sample.stockwatcher.client;
import com.google.gwt.user.client.rpc.RemoteService;
import com.google.gwt.user.client.rpc.RemoteServiceRelativePath;
@RemoteServiceRelativePath("stockPrices")
public interface StockPriceService extends RemoteService {
StockPrice[] getPrices(String[] symbols) throws DelistedException;
}
You need to make two changes to the service implementation (StockPriceServiceImpl).
import com.google.gwt.sample.stockwatcher.client.DelistedException; ... public StockPrice[] getPrices(String[] symbols) throws DelistedException { Random rnd = new Random(); StockPrice[] prices = new StockPrice[symbols.length]; for (int i=0; i<symbols.length; i++) { if (symbols[i].equals("ERR")) { throw new DelistedException("ERR"); } double price = rnd.nextDouble() * MAX_PRICE; double change = price * MAX_PRICE_CHANGE * (rnd.nextDouble() * 2f - 1f); prices[i] = new StockPrice(symbols[i], price, change); } return prices; }
At this point you've created the code that will throw the exception. You don't need to add the throws declaration to the service method in StockPriceServiceAsync.java. That method will always return immediately (remember, it's asynchronous). Instead you'll receive any thrown checked exceptions when GWT calls the onFailure(Throwable) callback method.
In order to display the error, you will need a new UI component. First think a moment about how you want to display the error. An obvious solution would be to display a pop-up alert using Window.alert(String). This could work in the case where the user receives the error while entering stock codes. But in a more real-world example, what would you want to happen if stock was delisted after the user had added it to the watch list? or if you need to display multiple errors? In these cases, a pop-up alert is not the best approach.
So, to display any messages about failing to retrieve stock data, you'll implement a Label widget.
.negativeChange {
color: red;
}
.errorMessage {
color: red;
}
private StockPriceServiceAsync stockPriceSvc = GWT.create(StockPriceService.class);
private Label errorMsgLabel = new Label();
// Assemble Add Stock panel.
addPanel.add(newSymbolTextBox);
addPanel.add(addButton);
addPanel.addStyleName("addPanel");
// Assemble Main panel.
errorMsgLabel.setStyleName("errorMessage");
errorMsgLabel.setVisible(false);
mainPanel.add(errorMsgLabel);
mainPanel.add(stocksFlexTable);
mainPanel.add(addPanel);
mainPanel.add(lastUpdatedLabel);
Now that you've built a Label widget to display the error, you can finish writing the error handling code.
You will also want to hide the error message if the error is corrected (for example, if the user removes the ERR code from the stock table).
public void onFailure(Throwable caught) {
// If the stock code is in the list of delisted codes, display an error message.
String details = caught.getMessage();
if (caught instanceof DelistedException) {
details = "Company '" + ((DelistedException)caught).getSymbol() + "' was delisted";
}
errorMsgLabel.setText("Error: " + details);
errorMsgLabel.setVisible(true);
}
private void updateTable(StockPrice[] prices) {
for (int i=0; i < prices.length; i++) {
updateTable(prices[i]);
}
// Display timestamp showing last refresh.
lastUpdatedLabel.setText("Last update : " +
DateTimeFormat.getMediumDateTimeFormat().format(new Date()));
// Clear any errors.
errorMsgLabel.setVisible(false);
}
At this point, you've created and checked for an exception—the delisted stock code "ERR". When StockWatcher makes a remote procedure call to retrieve stock data for the delisted stock code, the call fails, an exception is thrown, and then handled by displaying an error message.
At this point, you've made remote procedure calls to get stock data from the server.
For more information about GWT RPC, see the Developer's Guide, Remote Procedure Calls.
During testing, you can use development mode's built-in servlet container to test the server-side code for your RPC services—just as you did in this tutorial. When you deploy your GWT application, you can use any servlet container to host your services. Make sure your client code invokes the service using the URL the servlet is mapped to in the web.xml configuration file.

A Missouri hospital is caring for 12 sets of twins all born this week
by CNN(CNN) — While much of America was gathering around a dining table on Thanksgiving, this hospital stayed busy caring for not one, not two, not even three, but 12 sets of newborn twins.
The cuteness overload occurred this week at Saint Luke’s Hospital in Kansas City, Missouri. Staff believe it’s the largest number of twins the hospital has ever cared for at once.
“We always see multiples in here, but not 12 sets at one time,” nurse Danielle Gathers told CNN affiliate KMBC.
And, predictably, they’re incredibly cute.
Every set of twins was born this week — all between five and 14 weeks early, a spokeswoman for the hospital told CNN. They’re being cared for by staff in the neonatal intensive care unit.
Though some of the babies are looking at longer stays in the hospital than others, new mom Amanda Tollifer told KMBC she’s hoping her new bundles of joy will be home by Christmas.
“It’s our ultimate goal,” she said.

I finally found Jack Palevich's post talking about exporting the POSIXLY_CORRECT environment variable as follows.
POSIXLY_CORRECT=1 port install git-core +svn +bash_completion
Of course now I’ve run into an issue with tcl…. *sigh*, but I’ve seen the patch issue above crop up a few times, and this certainly seems to be fixing it.
It’s bad enough that MacPorts and Fink can’t depend upon Apple to provide sane libraries and headers in OS X, and thus you end up with most of another whole freaking operating system in /opt/local or /sw, but I simply refuse to have both installed, no matter how frustrating it is that I can’t get all the software I need working via just one of them.
Hey, thanks, this helped me. To fix the tcl issue, I then just didn’t use the POSIXLY_CORRECT variable, and it finished correctly.
yeah, I should have updated this with me working out the same thing. :)
Glad you found it useful!
