More locking improvements in Infinispan 5.1.0.BETA4
The latest beta in the Infinispan 5.1 "Brahma" series is out. So, what’s in Infinispan 5.1.0.BETA4? Here are the highlights:
-
A hugely important lock acquisition improvement has been implemented that results in locks being acquired in only a single node in the cluster. This means that deadlocks as a result of multiple nodes updating the same key are no longer possible. Concurrent updates on a single key will now be queued in the node that 'owns' that key. For more info, please check the design wiki and keep an eye on this blog because Mircea Markus, who’s the author of this enhancement, will be explaining it in more detail very shortly. Please note that you don’t need to make any configuration or code changes to take advantage of this improvement.
-
A bunch of classes and interfaces in the core/ module have been migrated to an api/ and commons/ module in order to reduce the size of the dependencies that the Hot Rod Java client had. As a result, there’s been a change in the hierarchy of Cache and CacheContainer classes, with the introduction of BasicCache and BasicCacheContainer, which are parent classes of existing Cache and CacheContainer classes respectively. What’s important is that Hot Rod clients must now code againts BasicCache and BasicCacheContainers rather than Cache and CacheContainer. So previous code that was written like this will no longer compile:
import org.infinispan.Cache; import org.infinispan.manager.CacheContainer; import org.infinispan.client.hotrod.RemoteCacheManager; ... CacheContainer cacheContainer = new RemoteCacheManager(); Cache cache = cacheContainer.getCache();
Instead, if Hot Rod clients want to continue using interfaces higher up the hierarchy from the remote cache/container classes, they’ll have to write:
import org.infinispan.BasicCache;
import org.infinispan.manager.BasicCacheContainer;
import org.infinispan.client.hotrod.RemoteCacheManager;
...
BasicCacheContainer cacheContainer = new RemoteCacheManager();
BasicCache cache = cacheContainer.getCache();
Previous code that interacted against the RemoteCache and RemoteCacheManager should work as it used to:
import org.infinispan.client.hotrod.RemoteCache;
import org.infinispan.client.hotrod.RemoteCacheManager;
...
RemoteCacheManager cacheContainer = new RemoteCacheManager();
RemoteCache cache = cacheContainer.getCache();
We apologise for any inconvenience caused, but we think that the Hot Rod clients will hugely benefit from this vastly reducing the number of dependencies they need. * Finally, a few words about the ZIP distribution file. In BETA4 we’ve added some cache store implementations that were missing from previous releases, such as the RemoteCacheStore that talks to Hot Rod servers, and we’ve added a brand new demo application that implements a near-caching pattern using JMS. Please be aware that this demo is just a simple prototype of how near caches could be built using Infinispan and HornetQ.
As always, please keep the feedback coming. You can download the release from here and you get further details on the issues addressed in the changelog.
Cheers, Galder


Five Things You Need to Know About Hammer.js 2.0
Hammer.js is a JavaScript library that makes touch events easier to identify, handle and manipulate. Recently, Hammer.js was upgraded from 1.1.3 to 2.0 and the API was drastically changed. If you’re using Hammer.js 1.x at work or for fun, interested in Hammer.js, or intrigued by touch events in general (but haven’t actually used them), this article is meant for you!
The Gilt team uses Hammer.js in many of our carousels for tablets, but otherwise sticks to native touchstart and touchend events. In creating a personal project that made extensive use of Hammer.js 1.x, I found it to be an extremely helpful library for identifying complex touch events like pinch and swipe. I also found that it lacked a full set of API features, so I wrote some simple helpers and a wrapper to make Hammer easier to use for myself. The look and feel of Hammer 2.0’s API is completely different from that of 1.x, and includes many of the features that I believed Hammer.js lacked.
These are the top five things I think everyone should know about Hammer 2.0 and how it’s different from Hammer 1.x:
1. Multiple Hammer Instances
In Hammer 1.x, the Hammer creators advised you to create a single Hammer instance on the page. This instance would most likely be bound to the body, so all touch events would be listened for. As events happened on the page, the Hammer instance would act as a publisher and notify subscribers about touch events. The Hammer instance could be subscribed to different touch events.
var armAndHammer = new Hammer(bodyElement, options);
armAndHammer.on(‘hold’, handleHoldEvent(ev));
In Hammer 2.0, you can (and are advised to) create multiple Hammer instances on the page and bind them to the specific DOM elements where they are needed. The new API feels much more like jQuery event-binding and much less like pup-sub.
var armAndHammer = new Hammer.Manager(el, options);
// or
var armAndHammer = new Hammer(el, options);
Initially, I was apprehensive about the new API approach. The pup-sub model was lightweight and easy to conceptualize, but the approach came at a cost. In Hammer.js 1.x, the Hammer instance notified the subscriber about every touch event on the page, and the subscriber was responsible for filtering touch events to ensure that the element that had been touched/tapped/etc. was indeed the element they wanted to act on.
armAndHammer.on(‘hold’, function (ev) {
if (ev.target === holdEl ) {
handleHoldEvent(ev);
}
});
Using Hammer 2.0, each Hammer instance is bound where the event happens and ensures the correct touch event happens on the correct element.
2. The Manager
In Hammer 2.0, each Hammer instance is called a Manager. A Manager can be instantiated by calling either
var armAndHammer = new Hammer.Manager(el, options);
or
var armAndHammer = new Hammer(el, options);
The single Hammer instance in Hammer 1.x can also be considered a Manager. In 1.x, the single Hammer Manager automatically listened to every Hammer touch event and broadcast every event it received, whether or not the developer wanted it to–or whether it was even necessary. For example, even if there were no subscribers to the pinch event, Hammer would calculate and publish any and all pinch events. If you were not specifically listening to this event, you would see no true effects on the page as no functions would be called via pub-sub. That being said, calculating touch events is not a simple JavaScript operation and it was unnecessary for the single Hammer Manager to listen for unused touch events.
In 2.0, each Hammer instance is called a Manager. In 2.0 Managers bind to specific elements and are only responsible for the events associated with those elements. To phrase it another way: Rather than assume you are interested in all touch events for a specific element the Hammer instance is bound to, Hammer 2.0 enables developers to create empty Managers that listen to zero events and then specify which touch events this Manager should listen for.
// empty Hammer instance
var armAndHammer = new Hammer.Manager(el, options);
Hammer 2.0 also allows users to create a Manager with a default set of events by skipping the Hammer.Manager constrictor and instead using the Hammer constructor:
var armAndHammer = new Hammer(el, options);
Although adding touch events to the Manager is more complex (because the developer is responsible for adding the touch events they are interested in), it gives the developer more specificity for their touch events. Additionally, this setup becomes much more testable because you know what the setup of the Manager will be on page load.
3. Recognizer
As I mentioned above, in Hammer 1.x the Manager knows about, listens for, and publishes all touch events. In 2.0, Managers start out empty, and the developer adds events to the Manager using objects called Recognizers. Recognizers are essentially objects that are responsible for groups of touch events in the same mutual category. For example, the swipe Recognizer listens for swipe, swipeleft, swiperight, swipeup, and swipedown events.
For each touch event you are interested in, you create a new instance of a Recognizer and add it to the Manager. Once the Recognizer is added, the Manager can listen for events from that Recognizer.
armAndHammer.add(new Hammer.Pan({event: 'pan'});
// the Recognizer has been added to the Manager
// and we can listen for pan events
armAndHammer.on('pan', handlePanEvent(ev));
In 1.x, the single Hammer instance essentially came with all Recognizers included. The benefits of adding Recognizers yourself are two-fold:
-
First, each Hammer instance is lighter and responsible for a subset of touch events.
-
Second, touch events can easily be customized. In Hammer 1.x, the options for events such as “hold event threshold” (time a user has to hold down before a hold event is fired) was set on the single Hammer instance, meaning every hold event had to be the same. In 2.0 developers can set the event options in the Recognizer, thus making touch events as customized as you wish them to be.
var myPanRecognizer = new Hammer.Pan({ direction: Hammer.DIRECTION_VERTICLE, threshold: 0 });
armAndHammer.add( myPanRecognizer );
4. Upgrade Path
The simplest upgrade path from 1.x to 2.0 can take as little as one hour. More complex upgrade paths utilizing some of Hammer’s new API features can take longer. When I upgraded from 1.1 to 2.0, it took me about four hours to upgrade a project that used six different touch events.
Here is a Gist that shows a simple and more complex upgrade path. In the simplest upgrade path, very little code has to change, and you can still rely on a single Hammer Manager bound to the body. If you use the Hammer constructor instead of the Hammer.Manager constructor, the Hammer Manager will have recognizers already added. You can still filter the touch events yourself for the appropriate element. The only difference is that you may have to change the options hash that you pass in.
In the more complex upgrade path, bind a Hammer Manager directly to the element you want to listen for touch events on, then add Recognizers for the appropriate touch event. Remove any DOM filtering code you had previously used. If you are only using Hammer in one place, upgrading to the simplest path is not a bad option and you may not even feel the need not upgrade at all. But if you are using Hammer for multiple DOM elements, upgrading to use multiple empty Hammer Managers and adding recognizers yourself is a better option and will hopefully simplify your code.
5. My favorite Hammer 2.0 feature and more
One of the biggest issues I had with Hammer 1.x was its inability to programmatically turn events on and off. On touch devices, it’s quite common to have many touch events associated with a single element/icon, but all the events may not be ‘active’ at the same time. Depending on the state of the phone for example, an app icon can be tapped, pressed, or dragged. In Hammer 1.x, I developed ways of checking the application state and preventing events from firing, but it was all very hacky.
In Hammer 2.0, Recognizers have their own states, controlled through an enable option that is passed when initializing a Recognizer. The default is true–i.e., the Recognizer is on–but you can also pass false or a function. Using a function is the best option to handle states for your touch events–it allowed me, for example, to easily and directly control the state of my web-app for each touch event. I highly recommend checking out this feature if/when you check out Hammer 2.0. (http://hammerjs.github.io/toggle-recognizer/)
Overall, I am very happy with the Hammer 2.0 upgrade. Its API is much easier to use and it has some really useful touch event handling features baked in.

 We like to look back and think about how good things used to be, to watch old movies and pretend like they aren’t really terrible. Auto companies know this, and that’s why they sell us the throwback designs. The look and feel of the ‘60s without the drum brakes and carburetors? Yes, please.
The typical way to do this is to sell a great vehicle for a few years, stop selling it for a few decades, then start selling a similarly-styled vehicle with the same or similar name. The Japanese motorcycle companies are all doing this; there’s the Honda CB1100, the Kawasaki W800, and the Suzuki TU250X among others.
Recently I was at a motorcycle dealership and noticed the unmistakable gauge cluster design of 30-odd years ago. The rolling odometer, the bold 55 mark on the speedometer, the indicator lights that are coloured lenses with white pictures on them, illuminated by a weak incandescent bulb.
It was on a Yamaha TW200. I remember this bike; I remember a friend had one on his farm when I was growing up.
I was pretty jazzed to see a new one in a dealership. Oh, nostalgia! Did Yamaha start making this bike again? No, it did not. It never stopped making it. Don’t call it a comeback. There have been a few minor changes; in 2001 it added electric start and a front disc brake. But most of the bike is exactly the same. Yamaha has been selling this bike, basically unchanged, for 32 years.
 It will go about 70 if you really want to, and it still has a carburetor. It is a go-anywhere motorcycle, and it often gets used for utility (read: a farm) or strapped to the back of off-road campers. I found this one in Telluride a few years ago:
Nostalgic design with zero development cost. Genius move, Yamaha.


This calculator uses actual constants and your information to calculate the level of emissions your car makes. This calculus not only uses the emission of the engine, but the emissions produced while making the car. For each 1000 pounds spent making a car, it's estimated that 750kg of CO2 have been emitted. Also we use the mean of KM travelled in a year, 15000km.
Now fill the gaps with your information


Sir : Idly perusing your website the other day, I couldn't help but be reminded of the time when I was trapped in a wind tunnel with an enormous bittern, having wandered in there by accident while attempting to draw badgers with my Dachshund (see cutting reproduced below). Perhaps I should have used a pencil instead? Yours amicably, Max Décharné of That Ilk

Frank Herbert
Innumerable small flourishes transform this book from
an indulgent sci-fi opera to an English language
classic. There are too many to go over; however, I do
want to highlight two of them. The first is the
character of the desert planet Arrakis. Herbert's
training as an ecologist comes through clearly, and he
is able to let readers understand the ecology and
biome of the Arrakeen landscape beautifully. I think
there are a lot of lessons to be learned by thinking
about what Herbert has to say about ecology and
biological systems. The second is Herbert's use of
epigraphs. They do a masterful job of fleshing out the
wider Universe and convey a sense of grandeur rarely
captured. They create the feeling of 'terrible
purpose' and contrast beautifully with the story as it
unfolds. I've revisited this book before, and think I
will again. It's my type of book.

We explore one of the main assumption of quantitative finance: assets returns are random.

One of the main pillar of quantitative finance is the assumption that assets’ returns behave in a random manner. Assets returns are normally distributed. It is a poor assumption as asset’s return are usually not normally distributed (fat tails, skewness, etc.), but it is one that is considered when approaching finance with a quantitative finance. Check this post on the normality of assets returns for a deeper dive into how random (or not) are assets returns.
Knowing the average daily return of SBUX over the last 3-ish year and using \(\bar{R} = \mu \delta t\) , or \(\mu = \frac{\bar{R}}{\delta t}\) and in our case \(\delta t = \frac{1}{252}\); we find the average annualized returns \(\mu\) is: -0.027 % with standard deviation \(\sigma\) of 33.2 % annualized.
We could plot the returns and the std of returns
library(ggplot2)ggplot(df |>drop_na(), aes(x = date, y = ret)) +geom_line() +geom_hline(yintercept = stdev, linetype ='dotted', color ='red', linewidth=0.8) +geom_hline(yintercept =-stdev, linetype ='dotted', color ='red', linewidth =0.8) +geom_hline(yintercept =2*stdev, linetype ='dotted', color ='red', linewidth=1) +geom_hline(yintercept =-2*stdev, linetype ='dotted', color ='red', linewidth =1) +xlab(label ='Date') +ylab(label ='Daily returns') +labs(title ='Daily returns')
We could standardized the returns (aka ensure they have a mean = 0 and std = 1) and compare it to the standard normal distribution.
This graph exemplifies what is very common with asset returns: fat tail, and under representation of returns just outside the mean. We discuss this further in our post: The normality of asset returns
The Euler-Maruyana Method to compute the SDE
We start with Equation 6 : \(S_{i+1} = S_i \cdot (1 + \mu \delta t + \sigma \phi \sqrt{\delta t})\)
# create one simulation for price ndays <-252price <-c()price[1] <-last(df$adjClose)phi =rnorm(ndays, mean =0, sd =1)for (i in2:ndays){ price[i] = price[i-1] * (1+ mu * delta_t + sigma * phi[i] *sqrt(delta_t))}yo <-tibble(x =1:ndays, price = price)ggplot(yo, aes(x, price)) +geom_line()
We can now create 100’s such simulations re-using previous code in a function.


FOUR WEDDINGS AND A FUNERAL A film review by Scott Renshaw Copyright 1994 Scott Renshaw
Starring: Hugh Grant, Andie MacDowell, Kristin Scott Thomas, Simon Callow, James Fleet, Charlotte Coleman. Screenplay: Richard Curtis. Director: Mike Newell.
Where romantic comedy is concerned, I am a tough sell. Too many of them seem to put across the impression that all you need to do is put two people on the screen and have them end up together, regardless of whether or not they are developed with an interesting conflict (or even speak to one another, as in the monstrously overhyped SLEEPLESS IN SEATTLE). I'm not going to turn into a pile of goo every time I see a screen kiss, but I will respond if I've spent two hours with two well-developed characters who seem to belong together. The new British comedy FOUR WEDDINGS AND A FUNERAL delivers only halfway. Hugh Grant turns in a charming, star-making performance in this uneven character piece, but Andie MacDowell always appears to be more of a prop than a person.
Grant stars as Charles, an inveterate bachelor who seems to find himself going to a friend's wedding every weekend. At one of these weddings, he spots a beautiful American named Carrie (Andie MacDowell), and finds himself instantly smitten. Their encounter is brief, but leaves him wondering about his own desire for a lasting relationship, and his ability to make it succeed. Then, to Charles' surprise, he meets Carrie again, at yet another wedding. However, there is an impediment to his affections: Carrie is engaged. While their flame smolders throughout their periodic meetings, Charles is ultimately left to deal with his own fears and to make some difficult decisions about what he really wants.
FOUR WEDDINGS AND A FUNERAL was written by Richard Curtis, co-creator of the popular British television import "Black Adder," a series not renowned for its sentimentality. And FOUR WEDDINGS is extremely winning when it's not focusing on relationships. The film is loaded with goofy moments--Charles the best man frantically trying to improvise for the forgotten wedding rings in the first ceremony; "Black Adder" vet Rowan Atkinson as a nervous novice priest malapropping his way through the second wedding; Charles trapped in a room with two newlyweds with impressive stamina. There are enough of these lively set pieces that FOUR WEDDINGS rarely lags for too long, and the laughs come at fairly regular intervals.
It is when Curtis shifts to his characters that he stumbles. Part of the problem is that in an attempt to create yet another ensemble friends piece he overloads the film with supporting characters, giving short shrift to the crucial relationship between Charles and Carrie. What's worse, almost all of the friends are drawn in only the sketchiest of terms; characters like Charles' cynical friend Fiona (Kristin Scott Thomas) and flatmate Scarlett (Charlotte Coleman) are given a few lines to establish their particular romantic dilemma, then sent to fade into the background. Only James Fleet, as befuddled aristocrat Tom, provides any spark to the proceedings. The simple fact is that I kept losing track of the relationships between all these people, and didn't particularly care when I could figure them out.
This lack of focus is inexcusable considering the cursory treatment Carrie's character is given. Part of FOUR WEDDINGS AND A FUNERAL's message about love is that we should all be looking for that one person who makes "lightning strike," and while the romantic sentiment is laudable it also assumes that we as an audience should recognize it when we see it. Hugh Grant, looking frighteningly like Harold Lloyd in his horn-rims, is an absolute delight; he turns Charles into a wonderful, funny, fallible character, and we want to see him happy. But Carrie is simply a plot device. We know virtually nothing about her except that Charles has a crush on her, and Andie MacDowell is not subtle enough an actress to fill in the blanks. It also might have been helpful to understand Charles' romantic history better, which could have been accomplished through a more complete picture of ex-girlfriend Henrietta, but that too is absent. There is much to recommend FOUR WEDDINGS AND A FUNERAL as a comedy; it's bright and spirited and well-paced. As a romance, it leaves much to be desired ... primarily a second party for the romantic pairing.

public class MailcapCommandMap extends CommandMap
Mailcap file search order:
The MailcapCommandMap looks in various places in the user's system for mailcap file entries. When requests are made to search for commands in the MailcapCommandMap, it searches mailcap files in the following order:
.mailcap
in the user's home directory.
mailcap
in the Java runtime.
META-INF/mailcap
.
META-INF/mailcap.default
(usually found only in the activation.jar
file).
(The current implementation looks for the mailcap
file
in the Java runtime in the directory java.home/conf
if it exists, and otherwise in the directory
java.home/lib
, where java.home is the value
of the "java.home" System property. Note that the "conf" directory was
introduced in JDK 9.)
Mailcap file format:
Mailcap files must conform to the mailcap file specification (RFC 1524, A User Agent Configuration Mechanism For Multimedia Mail Format Information). The file format consists of entries corresponding to particular MIME types. In general, the specification specifies applications for clients to use when they themselves cannot operate on the specified MIME type. The MailcapCommandMap extends this specification by using a parameter mechanism in mailcap files that allows JavaBeans(tm) components to be specified as corresponding to particular commands for a MIME type.
When a mailcap file is
parsed, the MailcapCommandMap recognizes certain parameter signatures,
specifically those parameter names that begin with x-java-
.
The MailcapCommandMap uses this signature to find
command entries for inclusion into its registries.
Parameter names with the form x-java-<name>
are read by the MailcapCommandMap as identifying a command
with the name name. When the name is
content-handler
the MailcapCommandMap recognizes the class
signified by this parameter as a DataContentHandler.
All other commands are handled generically regardless of command
name. The command implementation is specified by a fully qualified
class name of a JavaBean(tm) component. For example; a command for viewing
some data can be specified as: x-java-view=com.foo.ViewBean
.
When the command name is fallback-entry
, the value of
the command may be true
or false
. An
entry for a MIME type that includes a parameter of
x-java-fallback-entry=true
defines fallback commands
for that MIME type that will only be used if no non-fallback entry
can be found. For example, an entry of the form text/*; ;
x-java-fallback-entry=true; x-java-view=com.sun.TextViewer
specifies a view command to be used for any text MIME type. This
view command would only be used if a non-fallback view command for
the MIME type could not be found.
MailcapCommandMap aware mailcap files have the following general form:
# Comments begin with a '#' and continue to the end of the line.
<mime type>; ; <parameter list>
# Where a parameter list consists of one or more parameters,
# where parameters look like: x-java-view=com.sun.TextViewer
# and a parameter list looks like:
text/plain; ; x-java-view=com.sun.TextViewer; x-java-edit=com.sun.TextEdit
# Note that mailcap entries that do not contain 'x-java' parameters
# and comply to RFC 1524 are simply ignored:

Using new
and this
Instead of a "creation" function we would end up with an "initialization" function that looks something like this.
function initShoppingListItem(newObj, itemName, quantity) { newObj.itemName = itemName || ""; newObj.quantity = quantity || 1; newObj.complete = false; } var item = {}; initShoppingListItem(item, "cookies", 24);
Instead of creating an empty object and passing it to a function,
we can use JavaScript's new
keyword.
function ShoppingListItem(itemName, quantity) { this.itemName = itemName || ""; this.quantity = quantity || 1; this.complete = false; } var item = new ShoppingListItem("cookies", 24);
The function doesn't have an argument for the new object, because the
new object is referenced using the this
keyword.
By convention, constructor functions are capitalized.

LIFE ***1/2 (out of five stars) A review by Jamey Hughton
Starring-Eddie Murphy, Martin Lawrence, Rick James and Bernie Mac Director-Ted Demme Rated 14A
More MOVIE VIEWS by Jamey Hughton at: http://welcome.to/movieviews
Eddie Murphy has had his share of ups and downs during his career. Known for his notorious late 80's slump, Murphy has still managed to bounce back with a handful of hits in the past few years. With the exception of the dreadful Holy Man, he appears to be on pace for a full-fledged comeback.
Life was a great move on the part of Murphy and co-star Martin Lawrence, because it's a great showcase for both actors that never resorts to slap-sticky drivel.  Life is, in a sense, one great balancing act with Murphy on one end and Lawrence on the other. Amazingly, the scale never tips in either's favor due to the marvelous chemistry and wonderful contrast that each actor allows the other.
As the movie opens, we're introduced to Ray Gibson (Eddie Murphy), a two-timing pickpocket who schmoozes his way into a club. There he meets a successful businessman named Claude Banks (Martin Lawrence). Somehow, after multiple contrivances, the mismatched pair find themselves on their way to Mississippi on a moonshine run. When all is said and done, Ray and Claude have been framed for a murder that was actually committed by the town sheriff.
Hence the setting of Life: Mississippi State Prison, where the main characters come to realize their unlikely friendship is important, and become set on finding an fool-proof escape plan. The film takes us from the 30's all the way to the 90's, presenting a difficult task in showing how the aging process affects Ray and Claude. Luckily, Rick Baker handles the makeup effects of the two actors in a fantastic, Academy Award caliber manner. Not only do we believe the characters look as if they're 90 years old, but they sound like it, too. Murphy and Lawrence are completely convincing in the lead roles, even as crotchety old cons bickering over a game of cards. This is just one of the pleasant surprises that the film has tucked up it's sleeve.
While the ads are marketing Life as a straight arrow comedy, there is a hefty amount of dramatic material hidden at it's core. But the comedic aspects work wonderfully, wisely drawing strength from the talents of the two stars. The movie is more of a comedy than it is a drama, but in both senses, it's an overwhelming delight.
I could say a few bad things about the movie, but I don't want to. It's such a nice surprise, such a great vehicle for Eddie Murphy and Martin Lawrence, that it warrants a huge smile as the credits begin to roll.

Interest in this project was established, given the particularity of the topic and the multiple possibilities about visualization. It is a topic that we find entertaining to work and interesting, besides that already has a prestige and this could bring different opportunities for us. First contact established with Mario.
We identified with the hand of Mario his main target: happiness ranking and importance that anyone can understand it. Everyone!
We started to think what could be the best option for our problem. We constructed the first alternative and with feedback of our profesors,we met a good proposal with a choroplet map, parallel coordinates and bars!
Our advance was show it! Mario saw the first approach and told us his opinion about that, defining a little details.
A second feedback was given by our professors, these days we explore a little details to include and improve the current design. !
Claire is an expert in the Report, so it was necessary her opinion to confirm we were on the right way, fortunately we were!

There are two types of acetylcholine receptors (AChR) that bind acetylcholine and transmit its signal: muscarinic AChRs and nicotinic AChRs, which are named after the agonists muscarine and nicotine, respectively. These receptors are functionally different, the muscarinic type being G-protein coupled receptors (GPCRs) that mediate a slow metabolic response via second messenger cascades, while the nicotinic type are ligand-gated ion channels that mediate a fast synaptic transmission of the neurotransmitter.

Amanita muscaria
|
|
Muscarinic receptors are characterised through their interaction with muscarine, a water-soluble toxin derived from the mushroom Amanita muscaria that causes substantial activation of the peripheral sympathetic nervous system through its binding to muscarinic AChRs, resulting in convulsions and even death. The muscarinic AChRs occur primarily in the CNS, and are part of a large family of G-protein-coupled receptors (‘G proteins’), which use an intracellular secondary messenger system involving an increase of intracellular calcium to transmit signals inside cells. Binding of acetylcholine to a muscarinic AChR causes a conformational change in the receptor that is responsible for its association with and activation of an intracellular G protein, the latter converting GTP to GDP in order to become activated and dissociate from the receptor. The activated G protein can then act as an enzyme to catalyse downstream intracellular events.
Muscarinic receptors are involved in a large number of physiological functions including heart rate and force, contraction of smooth muscles and the release of neurotransmitters. There are five subtypes of muscarinic AChRs based on pharmacological activity: M1-M5. All five are found in the CNS, while M1-M4 are also found in various tissues: M1 AChRs are common in secretory glands; M2 AChRs are found in cardiac tissue; M3 AChRs are found in smooth muscles and in secretion glands. M1, M3 and M5 receptors cause the activation of phospholipase C, generating two secondary messengers (IP3 and DAG) eventually leading to an intracellular increase of calcium, while M2 and M4 inhibit adenylate cyclase, thereby decreasing the production of the second messenger cAMP. The activation of the M2 receptor in the heart is important for closing calcium channels in order to reduce the force and rate of contraction.
Nicotinic receptors are characterised through their interaction with nicotine in tobacco. The nicotinic AChRs are ligand-gated ion channels that form pores in cells’ plasma membranes, mediating fast signal transmission at synapses. Nicotinic AChRs are involved in a wide range of physiological processes, and can be either neuronal or muscle-type. Muscle-type nicotinic AChRs are localised at neuromuscular junctions, where an electrical impulse from a neuron to a muscle cell signals contraction and is responsible for muscle tone; as such, these receptors are targets for muscle relaxants. The many types of neuronal nicotinic AChRs are located at synapses between neurons, such as in the CNS where they are involved in cognitive function, learning and memory, arousal, reward, motor control and analgesia.
The binding of acetylcholine to nicotinic AChRs brings about their activation. When two molecules of acetylcholine bind a nicotinic AchR, a conformational change occurs in the receptor, resulting in the formation of an ion pore. At the neuromuscular junction, the opening of a pore produces a rapid increase in the cellular permeability of sodium and calcium ions, resulting in the depolarisation and excitation of the muscle cell, thereby producing a muscular contraction.
The activation of neuronal nicotinic AChRs also causes the movement of cations through the opening of an ion channel, with the influx of calcium ions affecting the release of neurotransmitters. Nicotinic AChRs on a postganglionic neuron are responsible for the initial fast depolarisation of that neuron. However, the subsequent hyperpolarisation and slow depolarisation, which represent the recovery of the postganglionic neuron from stimulation, are mediated by muscarinic AChR types M2 and M1, respectively. The binding of nicotine can activate nicotinic AChRs, modifying the neurons in two ways: the depolarisation of the membrane through the movement of cations results in an excitation of the neuron, while the influx of calcium acts through intracellular cascades affect the regulation of certain genes and the release of neurotransmitters.
Nicotinic AChRs are composed of five types of subunits: alpha (a1-a10), beta (b2-b5), delta, epsilon and gamma. These subunits are found in different combinations in different types of nicotinic AChRs:
Ø Muscle nicotinic AChRs (adult neuromuscular junction): a1-e-a1-b1-d
Ø Muscle nicotinic AChRs (foetal extrajunctional): a1-g-a1-b1-d
Ø Neuronal nicotinic AChRs (CNS, PNS and developing muscle): (a7)5
Ø Neuronal and autonomic nicotinic AChRs (ganglion): a3-b4-a3-b4-b4 and a3-b2-a3-b4-a5
Ø Neuronal and autonomic nicotinic AChRs (brain): a4-b2-a4-b2-b2
Ø Epithelial and neuronal nicotinic AChRs (cochlea hair cells): (a9)5
Theses receptors span the membrane, containing extracellular, transmembrane and cytoplasmic domains, the latter being the most variable. Nicotinic receptors are always pentamers, with the subunits arranged symmetrically around a central receptor channel. The receptors always contain two or more alpha subunits, which are critical in acetylcholine binding. The acetylcholine-binding site is comprised of a dimer formed by the alpha subunits (principal component) plus an adjacent subunit (complementary component), where binding to both sites is required for the channel to open.
Neurotoxins frequently target the acetylcholine-binding site, reversibly blocking the opening of the ion channel and formation of a pore, thereby preventing cations from passing through. Neuronal nicotinic AChRs have been divided into two main groups based on their sensitivity to the snake venom toxin a-bungarotoxin (‘Snake Venom: Bungarotoxins’). The a-bungarotoxin-sensitive receptors are homomeric, containing a7 or a9, and are found primarily in pre- and post-synaptic neurons and in developing muscle. The a-bungarotoxin-insensitive receptors are heteromeric, containing combinations of a2-a6 and b2-b4, and which often modulate the release of other transmitters.

| bool pqxx::thread_safety_model::have_safe_strerror |
Does standard C library have a thread-safe alternative to strerror
?
If not, its strerror
implementation may still be thread-safe. Check your compiler's manual.
Without strerror_r
(strerror_s
in Visual C++) or a thread-safe strerror
, the library can't safely obtain descriptions of certain run-time errors. In that case, your application must serialize all use of libpqxx.
Referenced by pqxx::describe_thread_safety().
| bool pqxx::thread_safety_model::safe_kerberos |
Is Kerberos thread-safe?
false
.If your application uses Kerberos, all accesses to libpqxx or Kerberos must be serialized. Confine their use to a single thread, or protect it with a global lock.
Referenced by pqxx::describe_thread_safety().
| bool pqxx::thread_safety_model::safe_libpq |
Is the underlying libpq build thread-safe?
A "false"
here may mean one of two things: either the libpq build is not thread-safe, or it is a thread-safe build of an older version that did not offer thread-safety information.
In that case, the best fix is to rebuild libpqxx against (a thread-safe build of) a newer libpq version.
Referenced by pqxx::describe_thread_safety().
| bool pqxx::thread_safety_model::safe_query_cancel |
Is canceling queries thread-safe?
If not, avoid use of the pqxx::pipeline class in threaded programs. Or better, rebuild libpqxx against a newer libpq version.
Referenced by pqxx::describe_thread_safety().
| bool pqxx::thread_safety_model::safe_result_copy |
Are copies of pqxx::result and pqxx::binarystring objects thread-safe?
If true
, it's safe to copy an object of either of these types (copying these is done very efficiently, so don't worry about data size) and hand the copy off to another thread. The other thread may access the copy freely without any concurrency concerns.

Hey, this is just an ad for the rather large commit I just put out. It doesn't add too much new stuff, instead it is doing what I do best, proving the same things other people did but better. :) It's focused primarily on the measure theory development, with the hope that I can bring down some of the compile times in that area. But there are some more substantive changes:
outer_measure.trim
is the truncation of an outer measure to a measurable spacemeasure_space
was renamed to measure
. There is a good sense of what a measure space could be, and this wasn't it.measure
and outer_measure
now have coe_fn instances so you don't need to refer to the underlying measure_of
function.measure
extends outer_measure
, so in particular it contains a field that is the outer measure projection, rather than containing a function only defined on measurable sets and recovering the outer measure by extension. In order to ensure we don't add extra measures, we require that a measure is trimmed
in the sense above.is_complete
asserts that a measure is complete (every null set is measurable)is_null_measurable
is the property of differing from a measurable set by a null set. It is proven that this is a sigma algebra, and a measure extends unchanged to this larger algebra; this is the completion of the measure.lebesgue
has mostly the same theorems but the proofs are rather different. In particular the proof that intervals are measured correctly uses compactness instead of the least upper bound property.Icc
is the closed intervalMario do you know about Haar measure? There's a canonical measure on any locally compact Hausdorff topological group (for example the real numbers).
The proof is "do the same as for the real numbers, but with an arbitrary locally compact Hausdorff topological group".
although some details are a lot more fiddly if I'm honest...
I have heard of it, but I've never done anything with it besides getting uncomfortable about "unique up to a multiplicative constant"
Lebesgue is also only determined up to a multiplicative constant on a finite dimensional real vector space
Well, who said [0,1] should have measure 1...
Oh, I forgot to mention I added scalar multiplication of measures; they are unfortunately not a module since the base "ring" is ennreal
If you talk about [0,1] then you've already chosen a basis of your 1-dimensional vector space
yes, my comment was supposed to be before yours :-)
Too bad we miss an opportunity to enjoy module type class hell
If CS people are happy to divide by 0, why can't they multiply by infinity?
Just make it 0 :-)
actually ennreal
is surprisingly nice as an ordered semiring
the fact that it is a complete lattice really helps
That's the trouble: if I understand correctly Mario is happy to multiply by infinity
a basis of your 1-dimensional vector space
It's not a vector space
affine space I should say
is there a notion of semi-vector space in the literature?
there are no negatives
I am amazed that this is not already in Lean
You know we already don't want to talk about semirings
I guess a monoid is just a semi-module over N
I find of am as well. We have semi everything else, but modules pick right up at rings
actually maybe that's a commutative monoid
A nat-semi-module is a commutative monoid
but if the scalar field is something else then it's different
I'm curious about all this integration stuff in mathlib. I never tried to use it or even looked at it. Can we do crazy things like proving the integral of id
on [1, 2]
is 3/2
?
Hey, this is just an ad for the rather large commit I just put out. It doesn't add too much new stuff, instead it is doing what I do best, proving the same things other people did but better. :smiley:
Thanks for that, @Mario Carneiro!
you were the one who mentioned the issue with meaure'_union
, right? I may have gone a bit overboard. :)
you were the one who mentioned the issue with
meaure'_union
, right?
Indeed, I was.
I may have gone a bit overboard. :smiley:
No problem! As long as you think it improved things.
Actually I have a problem too -- Fermat's Last Theorem can't currently be proved by finish
-- can you fix it for me Mario?
Kevin, the proof is by ᛗᛃᛟᛚᚾᛁᚱ
This is the Mario
variation of the ᛗᛃᛟᛚᚾᛁᚱ
tactic.
Speaking of hammers... I would like the decomposition theorem for mixed Hodge modules.
Yeah well I would like perfectoid spaces but I spent an hour last night writing the universal property of quotient groups :-/
should have told me to write it lol
Can you do algebraically closed fields Kenny? Chris' polynomials in one variable got accepted
Things are happening :-)
have you proved that k[X] is UFD?
https://github.com/kbuzzard/lean-perfectoid-spaces/blob/master/src/for_mathlib/quotient_group.lean
Do we even have a definition of UFD? It's pretty ugly
also I think we need "a in L/K: a is integral over K iff K(a) is finite"
Do we even have a definition of UFD?  Why not ask her if you can help?
We need more UG maths!
So we need more UG's, so that we can prove things by UG
. You do have access to two hammers!
let's say we've built L such that every polynomial in K[X] splits over L. How then do you show that L contains an algebraically closed field?
I think we should prove that K[X] is ED, that might help
That was almost there, right?
how should we prove "L is algebraically closed iff every finite extension of L is L"? that would involve building splitting fields
Except that the definition of ED wasn't optimal, so Chris had to work with degree + 1, or change the definition
I guess you want to do separable closure at the same time
my point is, there's a long way to go before we build algebraic closure
@Patrick Massot there is no integral in mathlibs measure theory, yet.
Oh, I forgot to mention I added scalar multiplication of measures; they are unfortunately not a module since the base "ring" is
ennreal
Yeah, semimodules would be nice to have. But up to now I didn't find any literature on them.
Oh, I didn't even imagine that. I was concerned about the fact that we don't have derivative and that could be a problem when wanting to compute integrals.
Well, the basic theory of integrals in measure theory doesn't need derivatives. It starts with integration over the Lebesgue measure. But there is some theory to be developed up to this point.
Sure, that's why I though we could have integrals but no mean of computing one
But let's have normed spaces first :wink:

ennreal
Yeah, semimodules would be nice to have. But up to now I didn't find any literature on them.
Maybe that's because most mathematicians think they're about as useless as distrib
s? Having said that, the existence of distribs proves that computer scientists have very different opinions to mathematicians as to what is "nice to have". What would mathlib want semimodules for? Is this something to do with compile times or something?
A related story : @Chris Hughes decided to do group actions yesterday, and his first question was "wait -- there's no mention of the inverse in the definition?". "No", I replied. "Oh dear, then we'll have to make it monoid actions if we want to get it into mathlib..."
semimodules
would help to abstract some basic proofs and syntax. we can abstract the scalar multiplication over measure
, outer_measure
, measurable functions into ennreal
, integrable functions into ennreal
, etc...
there is no integral in mathlibs measure theory, yet.
FYI I started working on that yesterday
nice
Does it mean you'll do derivatives as well?
no, like Johannes said, those two are completely unrelated except for a certain fundamental theorem
obviously the fundamental theorem can't be stated until we have both parts
There are indeed completely unrelated except for their fundamental relation
Anyway, it's already great to work on integrals
I don't even think they operate on the same kinds of spaces. There are spaces with integrals but no derivatives and vice versa
sure
so it's not like they are really different sides of the same coin, as in you could use either one to define the other
but I guess people care about R -> R and it's true there
it's an important special case, especially for teaching purposes
especially when it gives people the weird impression that these things are fundamentally related
they are related, but not fundamentally
in the foundational sense
Since you seem to be in an analytical mood, what about returning to the oldest open mathlib PR?
Well, measure theory isn't quite analysis
Let's put it next on the list
that will set us up for derivatives
there is no integral in mathlibs measure theory, yet.
FYI I started working on that yesterday
how is it now?
Johannes has taken over on that development
I think it might be merged now? I heard some talk about it but I haven't checked
ok

A conventional computer memory can be thought of as an array of cubbyholes, each of which can contain a piece of information. Each cubbyhole has a unique name, called its address or location. Typical memory systems provide two primitive operations: one that fetches the data stored in a specified location and one that assigns new data to a specified location. Memory addresses can be incremented to support sequential access to some set of the cubbyholes. More generally, many important data operations require that memory addresses be treated as data, which can be stored in memory locations and manipulated in machine registers. The representation of list structure is one application of such address arithmetic.
To model computer memory, we use a new kind of data structure called a vector (in JavaScript, a vector is essentially just a wrapper around an array). Abstractly, a vector is a compound data object whose individual elements can be accessed by means of an integer index in an amount of time that is independent of the index.[1] In order to describe memory operations, we use two primitive JavaScript functions for manipulating vectors:
For example, if v is a vector, then vector_ref(v, 5) gets the fifth entry in the vector v and vector_set(v, 5, 7) changes the value of the fifth entry of the vector v to 7.[2] For computer memory, this access can be implemented through the use of address arithmetic to combine a base address that specifies the beginning location of a vector in memory with an index that specifies the offset of a particular element of the vector.
We can use vectors to implement the basic pair structures required for
a list-structured memory. Let us imagine that computer memory is
divided into two vectors:
the_heads and
the_tails. We will
represent list structure as follows: A pointer to a pair is an index
into the two vectors. The
head of the pair is the entry in the_heads with the designated index, and the
tail of the pair is
the entry in the_tails with the designated index. We also need a
representation for objects other than pairs (such as numbers and
strings) and a way to distinguish one kind of data from another.
There are many methods of accomplishing this, but they all reduce to
using
typed pointers, that is, to extending the notion of
pointer
to include information on data type.[3] The data type enables the system to
distinguish a pointer to a pair (which consists of the pair
data
type and an index into the memory vectors) from pointers to other
kinds of data (which consist of some other data type and whatever is
being used to represent data of that type). Two data objects are
considered to be the same (===) if their pointers are
identical.[4]
Figure \ref{fig:box-and-pointer-memory}
illustrates the use of this method to represent the list list(list(1, 2), 3, 4), whose box-and-pointer diagram is also shown. We use letter
prefixes to denote the data-type information. Thus, a pointer to the
pair with index 5 is denoted p5, the empty list is denoted by
the pointer e0, and a pointer to the number 4 is denoted n4. In the box-and-pointer diagram, we have indicated at the lower
left of each pair the vector index that specifies where the head
and tail of the pair are stored. The blank locations in the_heads and the_tails may contain parts of other list
structures (not of interest here).
A pointer to a number, such as n4, might consist of a type indicating numeric data together with the actual representation of the number 4.[5] To deal with numbers that are too large to be represented in the fixed amount of space allocated for a single pointer, we could use a distinct bignum data type, for which the pointer designates a list in which the parts of the number are stored.[6]
A string
might be represented as a typed pointer that designates a
sequence of the characters that form the
string's
printed representation.
This sequence is constructed by the JavaScript reader when the character string
is initially encountered in input. Since we want two instances of a
string
to be recognized as the same
string
by === and we
want === to be a simple test for equality of pointers, we must
ensure that if the reader sees the same character string twice, it
will use the same pointer (to the same sequence of characters) to
represent both occurrences. To accomplish this, the reader maintains
a table, traditionally called the
obarray, of all the symbols it
has ever encountered. When the reader encounters a character string
and is about to construct a symbol, it checks the obarray to see if it
has ever before seen the same character string. If it has not, it
uses the characters to construct a new symbol (a typed pointer to a
new character sequence) and enters this pointer in the obarray. If the
reader has seen the string before, it returns the symbol pointer
stored in the obarray. This process of replacing character strings by
unique pointers is called
interning symbols.
Given the above representation scheme, we can replace each
primitive
list operation of a register machine with one or more
primitive vector operations. We will use two registers, the_heads and
the_tails, to identify the memory vectors, and will
assume that vector_ref and vector_set are available as
primitive operations. We also assume that numeric operations on
pointers (such as incrementing a pointer, using a pair pointer to
index a vector, or adding two numbers) use only the index portion of
the typed pointer.
For example, we can make a register machine support the instructions assign(reg$_{1}$,list(op("head"), reg$_{2}$)) assign(reg$_{1}$,list(op("tail"), reg$_{2}$)) if we implement these, respectively, as assign(reg$_{1}$,list(op("vector_ref"), reg("the_heads"), reg$_{2}$)) assign(reg$_{1}$,list(op("vector_ref"), reg("the_tails"), reg$_{2}$))
The instructions perform(list(op("set_head"), reg($\textit{reg}_{1}$), reg($\textit{reg}_{2}$))) perform(list(op("set_tail"), reg($\textit{reg}_{1}$), reg($\textit{reg}_{2}$))) are implemented as perform(op("vector_set"), list(reg("the_heads"), reg($\textit{reg}_{1}$), reg($\textit{reg}_{2}$))) perform(op("vector_set"), list((reg("the_tails"), reg($\textit{reg}_{1}$), reg($\textit{reg}_{2}$)))
The operation pair is performed by allocating an unused index and storing the arguments to pair in the_heads and the_tails at that indexed vector position. We presume that there is a special register, free, that always holds a pair pointer containing the next available index, and that we can increment the index part of that pointer to find the next free location.[7] For example, the instruction assign($\textit{reg}_{1}$, list(op("pair"), reg($\textit{reg}_{2}$), reg($\textit{reg}_{3}$)) is implemented as the following sequence of vector operations:[8] perform(op("vector_set"), list(reg("the_heads"), reg("free"), reg($\textit{reg}_{2}$))), perform(op("vector_set"), list(reg("the_tails"), reg("free"), reg($\textit{reg}_{3}$))), assign($\textit{reg}_{1}$, reg("free")), assign("free", list(op("+"), reg("free"), cons(1)))
The === operation list(op("==="), reg($\textit{reg}_{1}$), reg($\textit{reg}_{2}$)) simply tests the equality of all fields in the registers, and predicates such as is_pair, is_null, is_string, and is_number need only check the type field.
Although our register machines use stacks, we need do nothing special here, since stacks can be modeled in terms of lists. The stack can be a list of the saved values, pointed to by a special register the_stack. Thus, save($\textit{reg}$) can be implemented as assign("the_stack", list(op("pair"), reg($\textit{reg}$), reg("the-stack"))) Similarly, restore($\textit{reg}$) can be implemented as assign($\textit{reg}$, list(op("head"), reg("the_stack"))) assign("the_stack", list(op("tail"), reg("the_stack"))) and perform(op("initialize_stack")) can be implemented as assign("the_stack", cons(null))
These operations can be further expanded in terms of the vector operations given above. In conventional computer architectures, however, it is usually advantageous to allocate the stack as a separate vector. Then pushing and popping the stack can be accomplished by incrementing or decrementing an index into that vector.
const x = pair(1, 2); const y = list(x, x);
function count_leaves(tree) { return is_null(tree) ? 0 : ! is_pair(tree) ? 1 : count_leaves(head(tree)) + count_leaves(tail(tree)); }
function count_leaves(tree) { function count_iter(tree, n) { return is_null(tree) ? n : ! is_pair(tree) ? n + 1 : count_iter(tail(tree), count_iter(head(tree), n))); } count_iter(tree, 0); }
tagged dataidea we introduced in chapter 2 for dealing with generic operations. Here, however, the data types are included at the primitive machine level rather than constructed through the use of lists.
digitis a number between 0 and the largest number that can be stored in a single pointer.


Contains a string decribing the type of CPU emacs is running on.
The value will be one of:
Value Description i386 Intel x86 processor AXP Digital Alpha processor pa_risc HP PA Risc processor m68k Motorola 68000 family processor r6000 IBM Risc processor
Controls search case-folding. If non-zero, all searches will ignore the case of alphabetic characters when doing comparisons.
Contains the number of keystrokes between checkpoints. Every checkpoint-frequency keystrokes, all buffers which have been modified since they were last checkpointed and that have checkpointing enabled are written to disk. If the value is zero, checkpointing is disabled.
checkpoint-hook « checkpoint-buffers
Contains the name of an Emacs function which will be called when the checkpoint function is invoked. The checkpoint function should in some way checkpoint Emacs.
cli-name « The name of the CLI that started Emacs
Indicates the name of the CLI that invoked Emacs. The contents of this variable are used to tell subprocesses which CLI to use. You can alter its value to start a subprocess with a different CLI.
Contains the column at which program comments are to start. This is used by the language-dependent commenting features through the move-to-comment-column command.
Contains the string which will be used by the compile-it command if you type a null string to its prompt for a command to execute. Also, when you type a command, compile-it saves the command you type in the variable for later re-use.
This variable changes the way that Emacs input completion logic works.
When confirm-expansion-choice is true emacs will always prompt once more after expanding a unique input choice. It confirm-expansion-choice is false emacs will take the unique choice and use it with out further prompts.
control-string-convert-F-keys « 1
When control-string-convert-F-keys is true, the keys F6 to F20 and E1 to E6 are converted on input to a compact form. This improves Emacs' performance in a number of ways -- less memory used to store keymaps, and keyboard-handling uses less CPU time.
Before conversion the control sequence is:
CSI number ~
This is converted to CSI followed by one key whose value is 32 plus the above number.
See control-string-processing for general information.
control-string-convert-mouse « 1
When control-string-convert-mouse is true, all control sequences of the form:
CSI event;params... &w
are converted into \201 followed by one character which is the event number plus A.
See control-string-processing for general information.
control-string-convert-to-8-bit « [OP:
All control sequences which start with ESC <char> have an 8-bit equivalent control sequence. The string variable control-string-convert-to-8-bit contains all the <char>s that are to converted to their 8-bit form.
See control-string-processing for general information.
control-string-convert-to-CSI « \217\220\232
Contains a list of characters to be coerced into the single code for CSI. This reduces the number of keymaps that Emacs must maintain.
See control-string-processing for general information.
control-string-final-characters «ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}
Contains all the characters that mark the end of a control sequence. See ISO 2020 for full details.
See control-string-processing for general information.
control-string-intermediate-characters « !"\#$&'()*+,-./
Contains all the characters that follow the parameters and precede the final character of a control sequence. See ISO 2020 for full details.
See control-string-processing for general information.
This two dimensional array variable contains the parameters and parameter separators of the last control sequence that was parsed by Emacs. All elements of the array are strings.
Row 1 of the array contains the parameter value and Row 2 contains the value of the separator. The first parameter is in column 0 of the array the second in column 1 and so on.
Use bounds-of-array to find out how many parameters are in control-string-parameters.
control-string-parameters is a read-only variable.
See control-string-processing for general information.
control-string-parameter-characters « 123456789:<=>?
Contains all the characters that can be parameter characters. See ISO 2020 for full details.
See control-string-processing for general information.
control-string-parameter-separators « ;
Contains all the characters that can be parameter separator characters. See ISO 2020 for full details.
See control-string-processing for general information.
The master control for all the control string functions. Only when control-string-processing is true will any processing be performed.
control-string-processing changes the behaviour of a number of parts of Emacs:
- All keystrokes are compressed and processed according to the control-string variables.
- bind-to-key and local-bind-to-key will use the control-string variables to compress their <keys>key sequences.
- describe-bindings, describe-key and apropos-commands will use the built-in keyname table to print the names of keys.
Note: The values of the control-string...variables must only be changed in the file |emacs_control_strings.ml. If you wish to change any of these variables, do the following:
- Make a copy of emacs_library:emacs_control_strings.ml in your emacs_path:
- Rebuild your Emacs environment.
Controls the way that non-printing characters are displayed. If non-zero, control characters are printed with a leading up-arrow, otherwise they are printed as an octal number.
This read-only variable contains the name of the function that caused the breakpoint function to run. This variable is not altered from MLisp in a trace or breakpoint function.
Contains the name of te current buffer's abbreviation table. If you attempt to assign a value to it, the current buffer's abbreviation table is changed; the name you supply must be the name of an already-existing abbreviation table.
current-buffer-allocation-size
When read current-buffer-allocation-size returns the size in characters allocated for use in the current buffer.
Assigning a new, larger, value to current-buffer-allocation-size will increase the capacity of the current buffer.
It is not normally nessesary to use this variable. However as a performance enhancement it is sometimes useful.
If you plan to perform a complex set of operations on a buffer. These operations will cause the buffer to slowly grow to a much larger size. Assigning to current-buffer-allocation-size a suitable large value will reduce the CPU overhead of expanding the buffer is many small increments.
Defines whether or not the current buffer is checkpointable. If non-zero, when a checkpoint occurs, the buffer will be checkpointed if it has been modified. Otherwise, the buffer will not be checkpointed.
A buffer can never be checkpointed if the checkpoint-frequency variable is set to zero.
Contains the full file specification of the file associated with the current buffer. If the file does not already exist, the version number is omitted.
Setting this variable sets the filename to which the buffer is connected, but does not write the file. Also, the buffer is forced to be a File buffer.
If the buffer is not a File buffer, a null string is returned.
Controls whether the current buffer is journalled. If set to true, the buffer will be journalled.
A buffer will never be journalled if the journal-frequency is set to zero.
Contains the macro name associated with the current buffer.
Setting this variable sets the macro to which this buffer is connected. The buffer will be coerced into a Macro buffer.
If this buffer is not a Macro buffer, a null string is returned.
Contains the name of the currently selected buffer. You can change the name of the current buffer by assigning a new name to the variable. The new buffer name must not already exist.
current-buffer-end-of-line-style
Contains the end-of-line style of the file associated with the current buffer. The variable is one of variable, "crlf", "lf". The default value for new buffers is taken from the default-buffer-end-of-line-style variable.
current-buffer-RMS-record-attribute
We recommend you use the variable current-buffer-end-of-line-style to set the end-of-line style rather then use the RMS variables.
Contains the RMS record attribute of the file associated with the current buffer. The variable is one of variable, stream, stream-lf, or stream-cr. The default value for new buffers is taken from the default-buffer-RMS-record-attribute variable.
Contains the name of the current buffer's syntax table. Assigning to this variable changes the current buffer's syntax table. The specified syntax table must already exist.
Contains a string describing the type of the current buffer.
This read-only variable contains the name of the currently executing MLisp function. The value is not changed for functions executed in a trace or breakpoint function.
Contains the name of the current buffer's local keymap as set by the use-local-map function. Assigning the variable has the same effect as executing use-local-map. An existing keymap must be specified.
Contains the set of windows that are displayed on the screen. If read, current-windows returns a window-ring that represents the windows on the screen. When current-windows is set, the screen is restored from the window ring provided.

I am currently a PhD student studying Mathematics at Cardiff University, working alongside my supervisor Dr. Angela Mihai. My research title is 'elastic analysis of biogenic cellular structures' which at it's core is nonlinear elasticity and contact mechanics. To find out more, visit my research pages.
My private (self-funded) research involves lattice geometries within 3D printed objects, which gives the object a low density, yet its strong and can absort impacts and reduce vibration. This year it won a business ideas award: Cardiff Spark Ideas. If you would like to find out more, visit my lattice pages.
I love to share my passion with the public, hosting workshops and classes on 3D printing, deformation, fractals, tesselations and the internal geometric structure of objects around us. If you would like to me to organise something for your event, please get in touch! Some examples of past talks can be found on my research pages under 'Conferences & Workshops'.

Everything in boomerang is accessed through the BOOMR
object. Each plugin has its
own API, but is reachable through BOOMR.plugins
. This document describes the main
BOOMR
object.
To access any of the following, dereference the BOOMR object. eg: use BOOMR.version
to get the version
string.
The version number of the boomerang library. This is a string, formatted as major.minor.patchlevel. Standard version numbering rules apply
An object containing all plugins that have been added to boomerang. If you build your own plugin, it should be added to this object:
BOOMR.plugins.MyPlugin = { ... };
The init method that you to call to initialise boomerang. Call this method once after you've loaded the boomerang javascript. It accepts a single configuration object as a parameter. The configuration object is described in Howto #6 — Configuring boomerang.
a reference to the BOOMR
object, so you can chain methods.
Method that fires the page_ready
event. Call this only if you've set autorun
to
false when calling the init()
method. You should call this method when you determine that
your page is ready to be used by your user. This will be the end-time used in the page load time measurement.
See Howto #1b for an example of how to use this method.
a reference to the BOOMR
object, so you can chain methods.
The subscribe method is used to subscribe an event handler to one of boomerang's events. It accepts four parameters:
function(oEventData, oCallbackData);
this
within the callback function will refer to oCallbackScope
The page_ready
and page_unload
events are most useful to plugins while the
before_beacon
event is useful to code that wants to do something with the beacon parameters
before the beacon is fired. See the events section for more details.
a reference to the BOOMR
object, so you can chain methods.
Add one or more parameters to the beacon. This method is used by plugins to add parameters to the beacon, but may also be used by the page developer to tag the current request.
See Howto #5 for an example of using addVar()
.
This method may either be called with a single object containing key/value pairs, or with two parameters, the first is the variable name and the second is its value. All names should be strings usable in a URL's query string. We recommend only using alphanumeric characters and underscores, but you can use anything you like. Values should be strings (or numbers), and have the same restrictions as names.
a reference to the BOOMR
object, so you can chain methods.
Removes one or more variables from the beacon URL. This is useful within a plugin to reset the values of
parameters that it is about to set. It can also be used in a before_beacon
handler to stop
the beacon from being sent. See Howto #5 for how to do this.
This method accepts either a list of variable names, or a single array containing a list of variable names.
a reference to the BOOMR
object, so you can chain methods.
Request boomerang to send its beacon. Boomerang may ignore this request. When this method is called,
boomerang checks all plugins. If any plugin has not completed its checks (ie, the plugin's is_complete()
method returns false, then this method does nothing. If all plugins have completed, then this method fires the
before_beacon
event with all variables that will be sent on the beacon.
After all before_beacon
handlers return, this method checks if a beacon_url
has been
configured and if there are any beacon parameters to be sent. If both are true, it fires the beacon.

object, so you can chain methods.
Log a sMessage
to the configured logger with a level of sLevel
. This method
simply passes all logging information on to the configured logger. See
Howto #6 for details on how to configure this.
You probably want to use one of the convenience methods below instead that set the log level correctly.
nothing
Log sMessage
to the configured logger with a level of debug
. If sSource
is set,
it is appended to the string "boomerang." and set as the source of the log message. Use this
parameter to mention a plugin name and/or a line number/function name.

Fired when the page is usable by the user. By default this is fired when window.onload
fires,
but if you set autorun
to false
when calling BOOMR.init()
, then
you must explicitly fire this event by calling BOOMR.page_ready()
.
No additional event data is passed to the callback function. Any callback data is passed as specified in
the subscribe()
method.
Fired just before the browser unloads the page. This is fired when window.onbeforeunload
fires
(onunload
on Opera).
No additional event data is passed to the callback function. Any callback data is passed as specified in
the subscribe()
method.
Fired just before the beacon is sent to the server. You can stop the beacon from firing by calling
BOOMR.removeVar()
for all beacon parameters.
The callback function is called with two parameters. The first parameter is an object containing all
parameters that will be added to the beacon. The second parameter is the callback data object that
was passed in to the subscribe()
method. If the callback function removes all parameters
from boomerang, the beacon will not fire.
