Beware: in the worst case, a FLASH operation can
completely
lock up your calculator and there is no way than returning the
calcultator
to Texas Instruments in this case.
We (Tim. Singer and Romain Liévin) can not be responsible of
this.
Personnaly, I (Romain) have crashed a FLASH OS several times without
crashing the calculator but you have been warned !
A last remark: the link cables which are the more reliable and
efficient for these operations (especially OS flashing) are RS232
cables such as Grey TIGL, fastAVRlink (even at 4x = 38400 bauds) or
PIClink (not tested but should work). The SilverLink is slower than
others for FLASHing (strange, don't ask us why !).
There are 2 kinds of FLASH transfers:
- FLASH applications which are variables stored in the FLASH memory of
the calculator.
- AMS (Advanced Mathematic Software) which is the Operating System
of the calculator.
A Flash transfer is a one (large) transmission containing data (up
to 2 Mb for AMS). The file format that the TI-89 Graph Link software
uses
can be found in the file formats
section
of this documentation.
A FLASH OS must be transferred silently whereas FLASH apps can be transferred manually or silently. Silent transfers can only be done between a computer and a calculator, and require that the computer make the request or request-to-send.
This section does not cover sending of certificates or applications sold by TI.

[edit 2014/04/19: Some mistakes were made, but the interpretation follows. Sorry about that.]
Use Precision Recall area under curve for class imbalance problems. If not, Receiver Operating Characteristic area under curve otherwise.
When being confronted with the class imbalance problem, accuracy is a wrong metric to use. Usually, there are two candidates as metrics:
Which is better? What are the differences?
A ROC curve is plotting True Positive Rate (TPR) against False Positive Rate (FPR).
TPR is defined as:
FPR is defined as:
where TP = true positive, TN = true negative, FP = false positive, FN = false negative.
A typical ROC curve looks like this, which shows two ROC curves for Algorithm 1 and Algorithm 2.
The goal is to have a model be at the upper left corner, which is basically getting no false positives – a perfect classifier.
The receiver operating characteristic area under curve (ROC AUC) is just the area under the ROC curve. The higher it is, the better the model is.
A PR curve is plotting Precision against Recall.
Precision is defined as:
Recall is defined as:
A typical PR curve looks like this, which shows two PR curves for Algorithm 1 and Algorithm 2.
The goal is to have a model be at the upper right corner, which is basically getting only the true positives with no false positives and no false negatives – a perfect classifier.
The precision recall area under curve (PR AUC) is just the area under the PR curve. The higher it is, the better the model is.
Randy has given a great explanation here, plus a little of my understanding.
Since PR does not account for true negatives (as TN is not a component of either Precision or Recall), or there are many more negatives than positives (a characteristic of class imbalance problem), use PR. If not, use ROC.
A small example from Randy to illustrate this more clearly, with some bold text added myself:
For illustration, let’s take an example of an information retrieval problem where we want to find a set of, say, 100 relevant documents out of a list of 1 million possibilities based on some query. Let’s say we’ve got two algorithms we want to compare with the following performance:
- Method 1: 100 retrieved documents, 90 relevant. Thus, TP = 90, TN = 999890, FP = 10, FN = 10.
- Method 2: 2000 retrieved documents, 90 relevant. Thus, TP = 90, TN = 997990, FP = 1910, FN = 10.
Clearly, Method 1’s result is preferable since they both come back with the same number of relevant results, but Method 2 brings a ton of false positives with it. The ROC measures of TPR and FPR will reflect that, but since the number of irrelevant documents dwarfs the number of relevant ones, the difference is mostly lost:
- Method 1: 0.9 TPR, 0.00001 FPR
- TPR = TP/(TP + FN) = 90/(90 + 10) = 0.9
- FPR = FP/(FP + TN) = 10/(10 + 999890) = 0.00001
- Method 2: 0.9 TPR, 0.00191 FPR (difference of 0.0019)
- TPR = TP/(TP + FN) = 90/(90 + 10) = 0.9
- FPR = FP/(FP + TN) = 1910/(1910 + 997990) = 0.0019
Precision and recall, however, don’t consider true negatives and thus won’t be affected by the relative imbalance (which is precisely why they’re used for these types of problems):
- Method 1: 0.9 precision, 0.9 recall
- Precision = TP/(TP + FP) = 90/(90 + 10) = 0.9
- Recall = TP/(TP + FN) = 90/(90 + 10) = 0.9
Method 2: 0.9 precision, 0.045 recall (difference of 0.855) <= Randy’s post made a mistake here.- Method 2: 0.045 precision (difference of 0.855), 0.9 recall
- Precision = TP/(TP + FP) = 90/(90 + 1910) = 0.045
- Recall = TP/(TP + FN) = 90/(90 + 10) = 0.9
Obviously, those are just single points in ROC and PR space, but if these differences persist across various scoring thresholds, using ROC AUC, we’d see a very small difference between the two algorithms, whereas PR AUC would show quite a large difference.
To compare both methods, using ROC_AUC, we see that the FPR has a difference of 0.0019, which is very small. However, using PR_AUC, we see that the Precision has a difference of 0.855 which is much more pronounced.
Clearly, the PR is much better in illustrating the differences of the algorithms in the case where there are a lot more negative examples than the positive examples.
Use PR AUC for cases where the class imbalance problem occurs, otherwise use ROC AUC.
One note though, if your problem set is small (thus having fewer points in PR curve), the PR AUC metric could be over-optimistic because AUC is calculated via the trapezoid rule, but linear interpolation on the PR curve does not work very well, which the PR curve example above looks very wiggly. Interested readers may consult this paper of The Relationship between Precision-Recall and ROC Curves. Though, practically in a class imbalance problem nowadays, you should have a lot of examples so this should not be a problem.


I started with the compiler while I was still studying computer science at a university. At the beginning it was a really small project with only some arithmetics and logics implemented. Couple of years later I realized that it would be a good idea to add more functionalities, and to create a UI for it. My goal was that everyone who wants to understand how compiling works and how is assembly code executed on a CPU can see it and learn it using this tool. The whole time during development I tried to keep it as simple as possible, even though it was very hard to do so. Please enjoy learning and playing with it!
My name is Darijan Jankovic and I work as a software engineer in Zurich, Switzerland.

--- layout: archive title: Zulip Chat Archive permalink: /stream/116395-maths/topic/dfinsupp.20vs.20finsupp.html ---
Hi, I see that dfinsupp
is implemented using multiset
, pre_support
, and quotient
while finsupp
is implemented using finset
and support
. Is there any particular reason for this difference?
I mean, before looking into the sources I expected finsupp α β = dfinsupp α (λ _, β)
.
No good reason really. I think they were just written at different times by different people with different tastes.
As far as I understand, dfinsupp
works without some decidable_eq
assumptions while finsupp
doesn't (or creates noncomputable def
s).
Yep. That's why I chose it.

This is a promise coming from a service with a delay of 2 seconds: {{ libro }}
Notes:
Process to create and use a simple promise:
var myPromise = $q.defer();
and then returning myPromise.promise;
myPromise.resolve()
and myPromise.reject()
..then(success, failure)
to set the two ways to proceed. The success function will have the data as parameter, and the failure
function will have the error message as parameter..then(success, failure)
we can use .then(success).catch(failure)
.
It give us a higher degree of control.myPromise.notify()
in the factory function and including the getter function
as a callback to the .then()
in the controller. In this example we are logging the notification in
the console..finally()
.$q.all(promise1, promise2)
. If we do so, we will get
the resulting data in an array (each promise result will be an element of the array).

The first screen of the PRIDE XML Merger provides an overview of the role of the tool and informs the user of several design assumptions and restrictions. All the PRIDE XML files must be valid according to the PRIDE XML schema. A master file will be selected, which will serve as the basis for the final PRIDE XML file in terms of metadata. The identifications and spectra from the other files will be merged into the final output file. Users should note that the spectrum IDs from the source files will not necessarily be kept, but the internal references between peptide-spectrum_refs will be maintained.

While creating a new React project using Create React App is easy to do, the application that the default template generates contains items and content that aren’t essential for learning React. Distilling the generated application down to its essential items and content removes all distractions and allows you to focus on the basics.
When you finish this article, you should be able to:
Deleting files from the standard Create React App template can get tedious. To help save you time, App Academy has a custom template that you can use with Create React App to generate a simple React application!
Just run the following command:
Feel free to change my-app
to whatever you’d like. Once the command completes, browse to the generated application folder and run npm start
to start your application!
If you still just want to use the template that comes with Create React App and want to delete the files yourself, here’s that guide for you to follow.
To start, use Create React App to create a new application:
Then open the simple-project
folder in your code editor.
public
folderIn the public
folder, you’re only going to keep the index.html
file, so remove all of the following:
favicon.ico
robots.txt
logo192.png
logo512.png
manifest.json
The favicon.ico
and robots.txt
files are useful for applications that will actually be released and used by actual users, but not necessary for learning projects. The logo192.png
and logo512.png
image files are referenced in the manifest.json
file and are the icons that browsers use in various contexts (home screen, application menu, etc.) The manifest.json
file provides the metadata that’s used when your web app is installed on a user’s mobile device or desktop.
Now you can simplify the content of the index.html
to this:
<!DOCTYPE html>

<meta charset="utf-8" />
<title>React App</title>

To get to the above HTML, you can:
html:5
Emmet command to generate the boilerplate HTML and add a

element with an id
attribute set to root
(this is the element that your React application will render to).src
folderIn the src
folder, you’re going to keep the following files:
App.js
index.css
index.js
And remove all of the following:
App.css
App.test.js
logo.svg
serviceWorker.js
setupTests.js
The App.css
file is where you’d add styles that are scoped to the App
component and the App.test.js
file is where you’d write unit tests for the App
component. While you’re learning React, styling components and writing unit tests won’t be a focus. If you want to add some basic styles for your application, you can use the index.css
file to add global styles.
The logo.svg
file was part of the visual design of the generated application. The serviceWorker.js
file contains code that registers a service worker which allows the application load faster on subsequent visits if/when the application is released into production. The setupTests.js
file contains a single import statement for a module that helps make it easier to write unit test assertions on DOM nodes.
Now you can update the contents of the App.js
, index.css
, and index.js
files to the following:
// ./src/App.js
import React from 'react';
function App() {
return (

Hello world!

);
}
export default App;
// ./src/index.js
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
ReactDOM.render(
<React.StrictMode>
<App />
</React.StrictMode>,
document.getElementById('root')
);

| orb.gex - GrADS Extension Library for Satellite Orbit Masking |
orb.gex - GrADS Extension Library for Satellite Orbit Masking
run set_orb PARAM VALUE - Set internal parameters
run orb_track SATELLITE - Plot satellite orbits
display orb_mask(EXPR,SAT[,SWATH_WIDTH|SWATH_LEFT,SWATH_RIGHT[,dS]]) - Mask EXPR according to orbit
This library provides GrADS extensions (gex) for simulating satellite orbits and masking gridded variables according to these orbits. The calculation in this extension is meant to be a simulation of the satellite orbit and should not be used for forecasting real satellite overpasses. This calculation is not based on realtime Two-line Element (TLE) data.
GrADS datasets are given on a constant time interval. For a given GrADS time index t, satellite orbits can be simulated for the interval from t-0.5 to t+0.5. During this period the satellite describe a ground track which can be plotted with the command orb_track. With function orb_mask() one can mask gridded variables by setting to undefined those gridpoints which were not visited by the satellite, with the possibility of specifying the swath width and halo gridpoints.
When combined with a compression algorithm (such as in GRIB), satellite masked variables can use considerabily less storage space.
One can plot lines depicting the satellite ground track with the orb_track command:
ga-> open model ga-> d ts ga-> orb_track aqua
Instead of lines, one can also use marks to plot the ground track,
ga-> set_orb mark 6 ga-> orb_track aqua
This example shows how to set to undefined all grid points which have not been visited by the satellite. For a given GrADS time index t, the satellite ground track is computed from t-0.5 to t+0.5 and this simulated ground track is used to mask a variable:
ga-> open model ga-> define xts = re(ts,0.5) # higher resolution version ga-> set gxout grfill
ga-> d orb_mask(xts,aqua)
By default, the variable is masked according to the satellite ground track. However, it is also possible to specify the swath width (in km),
ga-> d orb_mask(xts,aqua,300)
You can also specify a halo, that is, additional gridpoints around the mask:
ga-> set_orb halo 2 ga-> d orb_mask(xts,aqua)
Halos are useful for interpolating gridded values to observation locations.
This command can be use to set several internal paramers, namely
Specify the timestep in seconds used to simulate the ground track. For example, a timestep of 60 seconds will cause of the (longitude,latitude) of the ground track to be computed every minute.
Specify the the type of mark used to plot the ground track. By default, MARK_TYPE=-1, and straight lines are used to plot the ground track. Other possibles values for MARK_TYPE are:
1 - plus sign 2 - open circle (default) 3 - closed circle 4 - open square 5 - closed square 6 - multiplication sign 7 - open diamond 8 - open triangle 9 - closed triangle 10 - open circle with vertical bar 11 - closed circle with vertical bar
Specify the number of zonal gridpoints to extend an orbital mask with. The parameter LEFT is the number of gridpoints west of the mask, while RIGHT is the number of gridpoints east of the mask. When RIGHT is missing it is set the same as LEFT.
Specify the number of meridional gridpoints to extend an orbital mask with. The parameter BELOW is the number of gridpoints south of the mask, while ABOVE is the number of gridpoints to the north of the mask. When ABOVE is missing it is set the same as BELOW.
Specify the number of meridional and zonal gridpoints to extend an orbital mask with. The parameter LEFT is the number of gridpoints to the west/south of the mask, while RIGHT is the number of gridpoints to the east/north of the mask. When RIGHT is missing it is set the same as LEFT.
This command plots the ground track for a given satellite. For a given GrADS time index t, the satellite ground track is computed from t-0.5 to t+0.5. This ground track is meant to be a simulation of the satellite orbit and should not be used for forecasting real satellite overpasses. This calculation is not based on realtime Two-line Element (TLE) data.
Currently the following NASA EOS satellites are supported
This function masks out those grind points which have not been visited by the satellite from grads time index t-0.5 to time index t+0.5. On can optionally specify a swath width.
GrADS expressions to be masked
Satellite name (Aqua, Terra, Aura, Calipso, CloudSat)
Width of the swath in kilometers, centered around the ground track. This gives SWATH_WIDTH/2 kilometers to the left/right of the ground track. Default is 0 (no swath).
Width of the swath in kilometers to the left and right of the satellite ground track. Default is 0 (no swath).
Swath resolution, in kilometers. Default is 10 km.

Hello h4ck@lyst,
We recently found and fixed a mistake that we’d like to tell you about. Passwords on WordPress.com are saved in a way that makes them extremely secure, such that even our own employees are unable to see your actual password – the one you enter to login to your WordPress.com account. However, between July 2007 and April 2008, and September 2010 and July 2011, a mistake in one of our systems used to find and correct bugs on WordPress.com accidentally logged some users’ passwords in a less secure format during registration.
We’ve updated our systems to prevent passwords from being logged this way in the future, so this will not happen again. We don’t have any evidence that this data has been accessed maliciously or misused, but to be on the safe side we are resetting your password since your account is among those affected.
Please change your password using this link or copy and paste the URL below into your web browser:
https://wordpress.com/wp-login.php?action=rp&key={key}&login={myUserId}
If the password you used when you registered on WordPress.com was one you use elsewhere, you should change it there, too. In the future, remember that it’s good practice to always use unique passwords for different services.
We are terribly sorry about this mistake. No one likes having to create new passwords and we’d like to include a 15% off coupon to say we’re sorry. The coupon can be used for a custom domain, a design upgrade, VideoPress, or a storage space increase. Just use the code below on any of the upgrades on the WordPress.com Store:

Latent representation of single cell experiments
Table of Contents
1 Introduction
We are interested in learning latent representations of single cell sequencing data. There are a number of potential questions which we could pursue:
- Can we make quantitative claims about clustering of cells in latent spaces?
- Can we learn hierarchical representations of cells?
- How should we think about differential expression between groups of single cells?
- How should we handle replicate data in latent variable models?
2 Cell clustering
Currently, the state of the art is to generate a visualization of cells in the latent space (e.g. principal components) and then make qualitative claims about the distances between points of interest.
Macosko et al 2015 developed Drop-Seq, a microfluidics platform which can now assay enough cells to start applying deep learning-based approaches.
We analyzed transcriptomes from 44,808 mouse retinal cells and identified 39 transcriptionally distinct cell populations, creating a molecular atlas of gene expression for known retinal cell classes and novel candidate cell subtypes.
For comparison, the well-studied CIFAR10 data set is 60,000 images.
A number of analyses in the paper could be improved upon using modeling-based approaches. However, most important is to first clarify what exactly the end goal of the analysis is.
We projected the remaining 36,145 cells in the data into the tSNE analysis. We then combined a density clustering approach with post hoc differential expression analysis to divide 44,808 cells among 39 transcriptionally distinct clusters (Supplemental Experimental Procedures) ranging from 50 to 29,400 cells in size (Figures 5B and 5C).
Can we say anything more than things we already know from low-dimensional visualization?
The most obvious thing to do is fit a variational auto-encoder to the data. This is already being done (Ding et al. 2017), but the goal is to make a better visualization.
For all the scRNA-seq datasets, we used principal component analysis (as a noise-reduction preprocessing step) to project the cells into a 100-dimensional space, and used the projected coordinates in the 100-dimensional spaces as inputs to scvis.
This is the one obvious thing to improve on.
To explicitly encourage cells with similar expression profiles to be proximal (and those with dissimilar profiles to be distal) in the latent space, we add the t-SNE objective function on the latent z distribution as a constraint.
Improving the visualization in this way seems counterproductive when the goal is to use the visualization to learn something new. In particular, in unsupervised learning of images the goal is actually the opposite: to put the examples on a dense manifold. The canonical example of useful representations learned like this is to trace along dimensions of this manifold, generating images which are smooth interpolations between the observations.
We next analyzed the scvis learned probabilistic mapping from a training single-cell dataset, and tested how it performed on unseen data. We first trained a model on the mouse bipolar cell of the retina dataset, and then used the learned model to map the independently generated mouse retina dataset
How to make this quantitative?
What exactly are we trying to learn from low-dimensional visualization, and how do we validate any novel insights?
In the machine learning community, latent representations are instead typically evaluated by showing that the latent states (say, clusters) can be used to predict independent labeled data (say, cell type). With DropSeq, it might be feasible to hold out data points, although we might have to worry about which points get held out. Better would be to generate replicate data, but if we fail to predict in replicate data, can we really say that was a failure of the model or a failure of the data?
We might have to tackle the more basic problem of correcting for confounders in single cell data.
The most basic approach is to fit a variational autoencoder (Kingma and Welling 2013) to the cells.
A more complicated approach would be to use an adversarial autoencoder (Makhzani et al., 2015) to include prior information about the latent space. For example, if we knew that the sample was a heterogenous mixture of some number of cell types, we could try to use a GMM prior on the latent states. This example was already pursued in the AAE paper.
We could try a DP prior on number of mixture components. Would AAE beat hierarchical Dirichlet process (Teh et al. 2005) in that case? However, this might be overcomplicated, and not help with the end inference goal.
3 Hierarchical representations
Ideally, we should learn not just individual genes, but gene sets/pathways/processes which change between cell states. We could do this either for cell cycle at one time point, or differentiation across several time points.
Can we learn the analogue of "high-level image features" from scRNA-Seq?
By analogy to computer vision, we need the equivalent of edge detectors, line detectors, etc. In simpler terms, we need the AlexNet (Krizhevsky et al 2012) of gene expression. One of the key advances in this area which we should build off of is DCGAN (Radford et al 2016).
4 Differential expression
In a bulk-sequencing DE analysis, we expose cells to different conditions, take an average over expression in those conditions, then ask about difference in the means.
But in single cells, different clusters in latent space don't really correspond to different conditions. Instead, the single cells are on trajectories between the states represented by the clusters.
Can we write this as regression over the latent dimensions instead of just comparing means between two groups?
5 Replicate data
A natural idea is to require that replicate observations are generated from the same latent state, which leads to an interesting modeling problem. Again from Macosko et al 2015:
The retinal STAMPs were generated on 4 different days (weeks apart), utilizing different litters and multiple runs in several sessions, for a total of seven replicates.
How should we think about replicates in the context of deep implicit models (or really, any kind of latent variable model)?
Do biological replicates really come from the same latent state? If we learn a hierarchical representation of latent states, can we require that they share some higher-level representation (assuming unknown variability is lower down)?
Should we try to learn a latent representation of technical artifacts also? Or should we try to simply correct for technical artifacts (like Buettner et al 2015).


An exponential function with base b is defined by f (x) = abx where a ≠0, b > 0 , b ≠1, and x is any real number. The base, b, is constant and the exponent, x, is a variable.
Most exponential graphs will have this same arcing shape.
This graph does not have a constant rate of change, but it has constant ratios. It is growing by common factors over equal intervals.
Exponential functions grow by common factors over equal intervals. As such, exponential functions are used to model a wide range of real-life situations (such as populations, bacteria, radioactive substances, temperatures, bank accounts, credit payments, compound interest, electricity, medicine, tournaments, etc.).
Any quantity that grows (or decays) by a fixed percent at regular intervals is said to possess exponential growth or exponential decay.
A horizontal translation may affect the increasing / decreasing (if
multiplied by a negative), the left hand / right hand behavior of the
graph, and the y-intercept, but it won't change the location of the
horizontal asymptote.
A vertical translation may affect the increasing / decreasing (if
multiplied by a negative), the y-intercept, and the location of the
horizontal asymptote. It will not change whether the graph goes without
bound or is asymptotic (although it may change where it is asymptotic) to
the left or right.
As x increases without bound, the quantity \((1 + \frac{1}{x})^{x}\) will
approach the transcendental number \(e\).
\(e=\lim _{x\to \infty }\left(1+{\frac {1}{x}}\right)^{x} \approx 2.7182\)
The limit notation shown is from calculus. The limit notation is a way of asking what happens to the expression as x approaches the value shown. The limit is the dividing line between calculus and algebra. Calculus is algebra with the concept of limit. People always have this dread of calculus that I can't understand. The calculus itself is easy. The reason people don't do well in calculus is not because of the calculus, but because of they are poor at algebra.

Theres nothing more annoying than having to repeat the same process over an over again, when this process is not smooth, or takes longer than it should.
At Parity shift, we know how to develop web based products which can help with this. So thats what we do.
We make products which make things less repetitive, less work, so you can focus on what you do best.
Our first product Porthole, came from identifying that a better UI for parts of AdWords would cut down on repetition, and just make that less of a pain point.
The same thing could be said about alot of things.
Got something which you wish was easier, or have a vision for a better way to do something. Please get in contact and start a discussion.

Need for Speed Heat Sets Franchise Record for Most Launch Week Players This Generation
by Alessio PalumboNeed for Speed Heat launched earlier this month on PC, PlayStation 4 and Xbox One, about two years after the previous installment in the arcade racing series, the much-dreaded Need for Speed Payback.
As it turns out, this time the developers at Ghost Games are enjoying a more positive reception from the community of fans. Earlier today, they revealed Need for Speed Heat to have just set a franchise record for most launch week players in this console generation.
Call of Duty Tops EMEAA Charts but Death Stranding Challenges
Nathan just posted our review and it's not exactly a ringing endorsement, though, as you can easily glean from the final summary quoted below.
Need for Speed Heat ditching its predecessor’s heavy-handed microtransactions and live-service nonsense is commendable, but in most other ways, this is actually a step back for the series. The game provides some solid arcade thrills, but a limited map, so-so visuals, slapdash action, and irritating cops weigh the experience down. If you’re desperate for a new open-world racer, Need for Speed Heat may be worth a spin, but most will want to wait until this one hits the used car lot.
Have you been playing Need for Speed Heat? If so, let us know your impressions by posting a comment in the section below.

The "struts-html" tag library contains JSP custom tags useful in creating dynamic HTML user interfaces, including input forms.
The tags in the Struts HTML library form a bridge between a JSP view and
the other components of a Web application. Since a dynamic Web application
often depends on gathering data from a user, input forms play an important
role in the Struts framework. Consequently, the majority of the HTML tags
involve HTML
forms. Other important issues addressed by the Struts-HTML tags are
messages
, error messages
, hyperlinking
and internationalization
.
Each of these tags must be nested within a  tag.
The Struts form
tag outputs a standard HTML form tag, and
also links the input form with a JavaBean subclassed from the Struts
ActionFormobject.
Each field in the form should correspond to a property of the form's
bean. When a field and property correspond, the bean is first used to
populate
the form, and then to store the user's input when the form is submitted
to the controller servlet.
The name of the bean and its class can be specified as a property to the
form tag, but may also be omitted. If omitted, the
ActionMappings
database (loaded from the struts-config.xml
file) is
consulted.
If the current page is specified as the input
property for an
action
, the name of the action
is used. The
type
property for the bean is also then taken from the
configuration,
via a Form Bean definition.
Here's a clip from the Struts Example configuration:
<action-mappings>

<action path="/logon"
type="org.apache.struts.webapp.example.LogonAction"
name="logonForm"
scope="request"
input="/logon.jsp">
</action>
< ... />
</action-mappings>
<form-beans>

<form-bean name="logonForm"
type="org.apache.struts.webapp.example.LogonForm"/>
< ... />
</form-beans>

Given this configuration, the HTML form tag for logon.jsp
will default to using "logonForm
" as its name property and
" org.apache.struts.webapp.example.LogonForm
" as the
attribute's type.
This way you can manage the namespace for your framework components from
the configuration file.
If the form tag does not find the form bean in any of the scopes (page, request, session, application), it creates one using the specified type.
The Struts ActionForm
class is equipped with standard
reset()
and validate()
methods, that can be used by
the controller to enable automatic data validation. See the
Users Guide
for more about Form Validation. An important aspect of validation is
reporting errors to the user. This can be handled by the Struts
errors
tag, which is discussed later in this
document
.
The form "field" tags in the Struts-HTML tag library share a common set of tag attributes that have the same meaning, no matter what field tag they are used with. These properties also accept Runtime Expressions, meaning you can set them with a scriptlet. The common attributes fall into four categories: Struts Common, HTML Navigation , Javascript , and CSS .
| name | The attribute name of the ActionForm
bean whose
properties are consulted when rendering the current
value of this
input field. If not specified, the bean associated
with the form
tag we are nested within is utilized. |
| property | Name of the request parameter that will be included with this submission, set to the specified value. |
| value | Value of the label to be used with this element. This value will also be submitted as the value of the specified request parameter. [Body of this tag (if any), or "Click"] |
Like Struts-Bean tags, the property attribute for the Struts-HTML tags accept simple, nested, and indexed expressions. For example, this tag:

corresponds to:
getMailingAddress().getStreet()
For more about using simple, nested, and indexed expressions with Struts, see the Struts-Bean Developers Guide.
| onblur | Executed when this element loses input focus. |
| onchange | Executed when this element loses input focus and its value has changed. |
| onclick | Executed when this element receives a mouse click. |
| ondblclick | Executed when this element receives a mouse - double click. |
| onfocus | Executed when this element receives input focus. |
| onkeydown | Executed when this element has focus and a key is depressed. |
| onkeypress | Executed when this element has focus and a key is depressed and released |
| onkeyup | Executed when this element has focus and a key is released |
| onmousedown | Executed when this element is under the mouse pointer and a mouse button is depressed. |
| onmousemove | Executed when this element is under the mouse pointer and the pointer is moved. |
| onmouseout | Executed when this element was under the mouse pointer but the pointer was moved outside the element. |
| onmouseover | Executed when this element was not under the mouse pointer but the pointer is moved inside the element. |
| onmouseup | Executed when this element is under the mouse pointer and a mouse button is released. |
| "parent" form tag only | |
| onreset | Executed if the form is reset. |
| onsubmit | Executed if the form is submitted. |
| accesskey | The keyboard character used to move focus immediately to this element. |
| tabindex | The tab order (ascending positive integers) for this element. |
| style | CSS styles to be applied to this HTML element. |
| styleClass | CSS stylesheet class to be applied to this HTML element. |
See the HTML Tags Reference for detailed information about the available tags in this tag library, and the complete list of valid attributes for each tag.
Aside from form processing, the Struts-HTML offers several other tags or tag properties to help with displaying error messages, messages, maintaining hyperlinks, and with internationalizing your application.
Message handling is an important part of any application. These messages can be informative messages and/or error messages for the user. Struts provides a generalized method for communicating runtime messages to users, based on the same technology used to provide internationalization. Messages and error messages can both be used by the messages tag.
The messages tag [since version 1.1] has basically the same functionality as the errors tag, but it iterates through the messages so any formatting of messages can be done in the JSP page. Also the header and footer for the message tag are optional.
By default, the messages tag will iterate through all pending messages. You can also specify a property when queuing a message, and then refer to that property in the messages tag. In that case, only the message(s) for that property will be displayed. This is helpful when you would like to place the message for a field next to the actual field.
Messages are often queued in the Action. The variable info is the ActionForm corresponding to this Action. :
ActionMessages messages = new ActionMessages();
messages.add(ActionMessages.GLOBAL_MESSAGE, new ActionMessage("userForm.insert", info.getUserName());
messages.add("activationDate", new ActionMessage("userForm.active", info.getSubscriptionLength());
This queues two messages, one is a global message and another for the "activationDate" field. To print all the messages together, simply place the messages tag anywhere in your JSP.

<bean:write name="message"/>

Or, you can place specific messages at different locations

<html:messages id="message" property="<%= org.apache.struts.action.ActionMessages.GLOBAL_MESSAGE %>">

<bean:write name="message"/>

<bean:write name="message"/>

By default, the actual message is retrieved from the application's standard message resource. This gives you a master list of the messages used by your application, and provides for internationalization. In the code snippet, the message corresponding to "userForm.insert" would be retrieved and displayed to the user at runtime.
userForm.insert={0} has successfully been inserted.
userForm.active=The account will be active for {0} months.
A header and footer are optional. The header will be rendered before iteration begins and the footer will be rendered after iteration is over. If a value is not assigned to the attribute, then nothing will be rendered for that attribute.

<bean:write name="message"/>

errors.header=
Validation Error

You must correct the following error(s) before proceeding:

errors.footer=

Error handling is an important part of any application, and curing an error often involves getting the user's help. Struts provides a generalized method for communicating runtime messages to users, based on the same technology used to provide internationalization.
In a Web application, it is common to reuse the input page to display error messages. The Struts error message tag can be placed wherever you would like the messages to display. If no messages are pending, nothing is printed.
By default, the errors tag will print all pending messages. You can also specify a property when queuing a message, and then refer to that property in the errors tag. In that case, only the message for that property will be displayed. This is helpful when you would like to place the message for a field next to the actual field.
Error messages are often queued in the ActionForm validate method. Here's a snippet from the Struts Example application:
ActionErrors errors = new ActionErrors();
if ((username == null) || (username.length() < 1))
errors.add("username", new ActionMessage("error.username.required"));
if ((password == null) || (password.length() < 1))
errors.add("password",
new ActionMessage("error.password.required"));
This queues two error messages, one for the "username" field and another for the "password" field. To print all the messages together, simply place the error tag anywhere in your JSP.

Or, you can place specific error messages at different locations

By default, the actual error message is retrieved from the application's standard message resource. This gives you a master list of the error messages used by your application, and provides for internationalization. In the code snippet, the message corresponding to "error.username.required" would be retrieved and displayed to the user at runtime.
error.username.required=
Username is required

Most often, error messages are displayed in a particular way. To make it
easy to format your messages, you can also specific an
errors.header
and errors.footer
string in your message resource. Typically,
you might want to render the messages in a different color, or set them
up to appear in an unordered list. Using the errors.header
and errors.footer
strings keeps the setup codes out of your
JSP until a message actually prints.
errors.header=
Validation Error

You must correct the following error(s) before proceeding:

errors.footer=

When implementing a Web application, it is usually a good idea to use relative references to other files in the same application. But in a dynamic application, the controller servlet often returns a completely different file than the one requested. (Often, the requested "file" doesn't actually exist, but represents an action for the controller to interpret.) Since relative references are resolved by the browser, they often won't work in a dynamic application.
To accommodate this, the Struts-HTML taglib provides a
<base>
tag that renders an HTML element with an href attribute pointing
to the absolute location of its page.
As a rule, you should place the Struts-HTML base tag in the  section of any JSP that uses relative references to other files.

The Java Servlet framework has built-in support for tracking a client through a session. Sessions are a useful way to compensate for the stateless nature of HTTP. Tracking a client can be done with either cookies or URL rewriting, cookies being preferred when available. Struts offers three tags that make it easy to write "session-aware" hyperlink references:
Each of these tags will automatically apply URL rewriting, to maintain session state in the absence of cookies. The content displayed for the hyperlink will be taken from the body of the tag. The base URL for the hyperlink is calculated based on properties given with the tag.
Normally, the hyperlink or URI you specify is left unchanged. If you would like to include dynamic parameters to the hyperlink or URI, you can pass those to the tags via a JavaBean. If there may be naming conflicts, you can also specify the scope that the tag searches (request, page, session, application).
To pass a single dynamic parameter, specify the parameter's name using
the paramId
attribute. You can then specify the name of the
JavaBean holding the value using the paramName
attribute, and
a particular property using paramProperty
.
So, a tag like
detail.html
would correspond to something like
<A HREF="detail.html?<%=
request.getAttribute("linkParams").getTarget()
%>">
To search all scopes (request, page, session, and application), omit
paramScope
.
The paramProperty
attribute may also be omitted, so long as
the named bean identifies a value that can be converted to a String.
To pass multiple dynamic parameters, you can store them in a
java.util.Map
, and use the name of the map for the paramName
. The
map must then contain one or more paramIds
and their
corresponding
values. As the Map is processed, the keys are assumed to be the names of
query parameters to be appended. The value associated with each key must
be either a String or a String array representing the parameter value(s).
If a String array is specified, more than one value for the same query
parameter
name will be created.
The HTML session tracking tags use several common attributes, that can
be organized into three groups, as follows. All of these attributes are
not used by all three tags (link
, rewrite
, and
img
), and so the tags using each attribute is given.
| forward, href, and page | |
|---|---|
| forward | [ link rewrite ] - Logical name of a global ActionForward that contains the actual content-relative URI of the destination of this transfer. This hyperlink may be dynamically modified by the inclusion of query parameters, as described in the tag description. You must specify exactly one of the forward attribute, the href attribute, the linkName attribute, or the page attribute |
| href | [ link rewrite ] - The URL to which this hyperlink will transfer control if activated. This hyperlink may be dynamically modified by the inclusion of query parameters, as described in the tag description. You must specify exactly one of the forward attribute, the href attribute, the linkName attribute, or the page attribute. |
| page | [ link rewrite ] - The context-relative path, starting with a slash, of the image to be displayed by this tag. The rendered URL for this image will automatically prepend the context path of this web application (in the same manner as the page attribute on the link tag works), in addition to any necessary URL rewriting. You must specify either the page attribute or the src attribute. |
| linkName, Target , and src | |
|---|---|
| linkName |
[ link ] - The anchor name to be defined within this page, so that you can reference it with intra-page hyperlinks. In other words, the value specified here will render a "name" element in the generated anchor tag. |
| target | [ link img ] - The window target in which the resource requested by this hyperlink will be displayed, for example in a framed presentation. |
| src | [ img ] - The URL to which this image will be transferred from This image may be dynamically modified by the inclusion of query parameters, as described in the tag description. This value will be used unmodified (other than potential URL rewriting) as the value of the "src" attribute in the rendered tag. You must specify either the page attribute or the the src attribute. |
| paramId, paramName, paramProperty, paramScope | |

lex_xl
takes an Excel formula and separates it into tokens. It returns a
dataframe, one row per token, giving the token itself, its type (e.g.
number
, or error
), and its level.
The parse tree is designed for analysis rather than computation, and may not support computation.
A simple plot()
function is provided that depends on the suggested
package ggraph
(which pulls in many other dependencies that can be tricky
to install).

Extra resources planned as temperatures expected to drop in the Lower Mainland
by Tarnjit ParmarSummary
Hunka says the dip in temperature means outreach teams will be trying to connect with homeless individuals
He says in cold weather, shelters are often filled to capacity, leaving others to deal with the harsh conditions
The coast is expected to experience freezing temperatures from -5 to -10 degrees Celsius
VANCOUVER (NEWS 1130) — Temperatures are set to dip in the Lower Mainland this week, prompting additional resources to be deployed to help people living on the streets.
Jeremy Hunka with the Union Gospel Mission says the dip in temperature means outreach teams will be trying to connect with homeless individuals.
 People face increase risk of anything from the emergency need from trying to get in from the cold to really complicated medical conditions,” he explains.
He says in cold weather, shelters are often filled to capacity, leaving others to deal with the harsh conditions.
“People die in the cold in Metro Vancouver and that’s heartbreaking to see, so it’s not an exaggeration to say that this can be a life and death emergency for people who are homeless.”
Hunka says they have two rescue vehicles that will be operating during the cold weather equipped with hot food, hot beverages, and survival gear.
He adds in previous years, shelters have overflowed with homeless people trying to get out of the cold, and some had to be turned away. This year, 100 additional shelter beds have been opened.
The coast is expected to experience freezing temperatures from -5 to -10 degrees Celsius.
