Building heterogeneous TypeScript libraries
A technique for compiling one or more TypeScript source files to a single JavaScript library file that can be used in both the browser and by Node.js applications.
By way of example
Our library source consists of a single TypeScript module called Lib spread across multiple source files (lib1.ts
and lib2.ts
) that exports a public API:
lib1.ts
module Lib {
export function f() {}
}
declare var exports: any;
if (typeof exports != 'undefined') {
exports.f = Lib.f;
}
lib2.ts
module Lib {
export var v = {foo: 42};
}
declare var exports: any;
if (typeof exports != 'undefined') {
exports.v = Lib.v;
}
The source file are compiled to a single JavaScript library lib.js
using the TypeScript compiler:
tsc --out lib.js lib1.ts lib2.ts
lib.js
var Lib;
(function (Lib) {
function f() {
}
Lib.f = f;
})(Lib || (Lib = {}));
if(typeof exports != 'undefined') {
exports.f = Lib.f;
}
var Lib;
(function (Lib) {
Lib.v = {
foo: 42
};
})(Lib || (Lib = {}));
if(typeof exports != 'undefined') {
exports.v = Lib.v;
}
lib.js
file now can be included on an HTML page with:
<script type="text/javascript" src="lib.js"></script>
Or in a Node.js application with:
var Lib = require('./lib.js');
The APIs are accessed via the module name e.g. Lib.f()
, Lib.v
.
Explanatory notes
The key to being able to import the code into Node.js with require('./lib.js')
is conditionally assigning public API objects to properties of the global exports
object e.g.
declare var exports: any;
if (typeof exports != 'undefined') {
exports.f = Lib.f;
}
exports
is a global object defined by CommonJS compatible loaders such as Node’s.- This code must be placed at the end of the source file outside the module declaration.
exports
will not be assigned in the browser (or any non-CommonJS environment where exports is not defined).- To minimize browser global namespace pollution all source is enveloped in a single open module (Lib) – this is not necessary in a module loader environment (e.g. Node.js).
- Multi-file “open” modules are not truly open – you must export any module objects that need to be accessed across file boundaries.
- TypeScript can emit CommonJS modules directly by prefixing module with the export keyword and using the compiler
--module commonjs
option, but there are two problems with this approach:- The generated code can only be loaded with a module loader and cannot be used in a browser unless you also depoly a suitable browser module loader.
- External modules must reside in a single source file (they are not open).
Scoping function wrapper
A variation of the above technique is to wrap the combined compiled file with a scoping function. This will ensure non-exported top level objects do not pollute the browser global namespace:
(function() {
:
})();
The browser API is hoisted to the global namespace by assignment to the browser window
object. The previous example becomes:
declare var exports: any;
if (typeof exports != 'undefined') {
exports.f = Lib.f;
}
else if (typeof window !== 'undefined') {
window['f'] = Lib.f;
}


AN ALL JEEP DAY...and what a day it was...Paul and I met up with those brave adventurous jeep owners at the McDonalds on the north side of town...Audrey, John, Kevin, John with his dad John, Ryan, Brian and Mike...up we headed towards the edge of Idaho Springs.
This is a trip that Paul and Jake scouted out. It is on the outskirts of Idaho Springs and has 2 designations... Locker Hill or Guard Rail Trail ... take your pick ... we had along with us as guest John Gamby's dad from Nebraska, and three Air Force cadets...Ryan, Brian and Mike. The first obstacle was interesting especially for Ryan and Brian but they did a great job and made through. It was a fun run through some old mining ruins with a fun hill at the end of it where we turned around and went back down.
A side road before Spring Creek trail that some people call Silver Creek. We had lunch at the bottom of this obstacle. All but Mike tried the hill and made it no problem.
We left the two vehicles which Mike and Ryan were driving and Ryan, Brian and Mike rode up the Spring Creek road with Audrey, John and Kevin. We met some people coming down from Spring Creek as it has become even more difficult. But all of our vehicles made it. John G. being open had some trouble but still made it up. John put a winch on for safety when the way he decided to try turned out to be a bit hairier than he had originally thought. The rain held off until we started back...it was a long day but one of some great 4 wheeling and lots of fun...Thank you to those who were able to make it...It proved to be a GREAT JEEP DAY...

In 1922, Japanese company Ezaki Glico Co., Ltd. launched its fortified Glico caramel in a distinctive red box. Forty-four years later, Ezaki Glico released a new product into their family of fine foods—a chocolate-coated, pretzel-like cookie stick. Inspired by the Japanese onomatopoeia for the snapping sound made while eating these crispy sticks, they named their new product "Pocky." Hence, Pocky Chocolate was born.
Flavours: Chocolate, Strawberry, Matcha Green Tea, Chocolate Banana, Cookie and Cream.


Examples
Below are 4 pitches from the NSynth validation set with annotated MIDI numbers 24 (f0 = 32.7Hz), 34 (f0
= 58.27Hz),
53 (f0 = 174.61Hz), and 75 (f0 = 622.25Hz). Each example is 4 seconds in length and is sampled at
16kHz.
A 2048 sample is extracted every 128ms and pitch is estimated using Pitch GRU (our algorithm), pYIN and
CREPE. Additionally, PyTorch audio's (torchaudio)
internal implementation is also used to estimate pitch for comparison.
For lower pitches (below 40) Pitch GRU gives more stable estimates than pYIN and CREPE. Pitched higher
than MIDI 40 Pitch GRU, pYIN and CREPE have approximately similar accuracies. Also, towards
the end of the signal (around 3 second mark in each example) all algorithms estimate incorrectly, except
pYIN which eventually corrects its estimates.

I'm a UX designer and design generalist, and I've been building my skills in the field for over five years. I earned a degree in Interactive Digital Media from U of T in 2015, and I've been working as part of a UX team at U of T ever since to design online tools and services that aim to make the lives of students and staff easier. I use design principles and ongoing feedback from users and project team members to inform everything I make, from sketches to prototypes to finished designs. See my UX work here!
My favourite design tools to use at the moment are Figma and InVision.
I have plenty of experience doing the following:

The last one on the chain.
The other activations on the chain are awaiting results before proceeding. (The inactive circles have already returned results and will never again represent executing code.)
Here are some equal strings:
"abc" equals "abc" "abc de" equals "abc de"
And here are some unequal strings:
"ab" !equals "abc" "abC" !equals "abc" "abc" !equals "aBc"
Here are the rules for string equality.
The symbol x
stands for a single character,
as does y
.
The symbol X
stands for a string of characters,
as does Y
.
The symbol +
stands for concatenation.
1. equals( "", "" ) = true 2. equals( "", X ) = false if X is not the empty string 3. equals( X, "" ) = false if X is not the empty string 4. equals( x+X, y+Y ) = false if x != y 5. equals( x+X, y+Y ) = true if x == y and equals( X, Y )
Rule 4 means that if you see two strings that start with different characters, they the strings are not equal. For example,
equals( "bat", "radio" ) = false
In the above example, x
is the character 'b',
X
is the string "at",
y
is the character 'r',
Y
is the string "adio".
Here is another example:
equals( "rat", "rat" ) = equals( "at", "at") // rule 5 equals( "at", "at" ) = equals( "t", "t") // rule 5 equals( "t", "t" ) = equals( "", "") // rule 5 equals( "", "" ) = true // rule 1
For another example,
equals( "rat", "ra" ) = equals( "at", "a") // rule 5 equals( "at", "a" ) = equals( "t", "") // rule 5 equals( "t", "" ) = false // rule 3
And yet another example,
equals( "rAt", "rat" ) = equals( "At", "at") // rule 5 equals( "At", "at" ) = false // rule 4

Updating copyright and intellectual property laws to meet the challenges of the networked environment has been a key focus for Congress, the courts, and state legislatures for several years. The Digital Millennium Copyright Act, the Sonny Bono Copyright Term Extension Act, peer-to-peer file sharing and digital rights management, and legislation to create additional protections for databases have dominated the agenda. Debate and consideration of a large number of copyright and intellectual property bills and court cases has occupied ARL staff this year. The latest news about copyright and intellectual property is in the E-news, Section One.
In a vastly different approach than in the U.S., where the recording industry has sued individual users and P2P file sharing services, the Society of Composers, Authors and Music Publishers of Canada (SOCAN) sought to make the ISPs liable for music downloaded by their customers. The Canadian Association of Internet Providers representing the ISPs argued that SOCAN should seek royalties for downloaded music from the websites that provide access to those works.

I consumed the 12mg of this compound orally and washed it down with some water. It tasted pretty gross. More gross than 2CT2.
T+00:30
This was much more potent than I had expected. It came on slowly, but with much strength. The first thing I noticed was a pleasant feeling throughout my body, not unlike 2CT2, coupled with some minor short-term memory scramble & confusion.
T+02:00
Once it really started going, my friend and I decided to go for a walk. On our walk, we were waiting at a “Don’t Walk” sign to cross a street. It was a fairly long light and I began to grow impatient. When the lights finally changed I felt quite exhilarated, that exhilaration quickly turned to confusion when I realized there was the sound of a large audience clapping and whistling, the moment I realized that the sound shouldn’t have been there, it was abruptly terminated.
I would look at clouds and try to pick out a face… I would look for eyes, nose and mouth, and as soon as I found a face in the clouds, it would begin to change, one time the eyes narrowed and the mouth opened wide, another just smiled, wider and wider until its mouth dissipated.
I saw two bright lights on the side of an apartment building, obfuscated by a few old trees, and the beams of light peeking through seemed to appear remarkably solid.
I could continue describing the rest of the myriad of visual distortions I had that evening, but I don’t want this thing to be too long.
I noticed it was devoid of any physical energy push unlike many other psychedelics. I had just as much vigor as I would have if I was sober, maybe less. AMT, LSD and MDMA to a degree wake me up and give me more energy, this was not the case with 2C-I.
T+02:45
We ended up in a very large sea of people, as it was Canada Day, and this was the place to be to see the fireworks, I started to get rather unnerved. I began to fear that I was expressing weird things through body language and offending people in the crowd. My friend felt anxious as well and we decided to retreat back to his apartment. Over the course of the walk back I realized that the body language thing was quite absurd, and felt a lot better.
During the walk and particularly when we returned to my friend’s apartment I noticed this compound made me voraciously thirsty to the same degree MDMA does. I definitely recommend watching your water intake with this stuff.
T+03:00
Once we were back, we conversed for a while. Our topics of conversation switched quite quickly. At one point where there was a break in the conversation, my friend made a peculiar groaning noise while staring off into space… When I asked him “What kind of noise was that?” he slowly replied “That’s my ‘I’m hallucinating noise’”. We both found this quite humorous and had a good long laugh.
I noticed as complacent and pleasant as this compound made me feel, it didn’t have even one hint of the empathy that MDMA exhibits.
T+04:30
Once I had come down I got a little down, not only sad that the trip was ending, but just sad for no real reason. It wasn’t unbearable by any means, just slightly annoying.
T+07:00
Completely down, and ready for bed. After I had retired for the evening, I woke up all disoriented and hallucinating three or so hours into my slumber. I was hallucinating like crazy, I didn't know where I was and the things on my bed sheets were morphing. Other than that brief episode, I had a very restful sleep, for a full 8 hours, and awoke rather refreshed. The following days were fine, like I hadn’t even taken the drug at all. If anything, I was a little cheerier than normal.
As for physical side effects:
No nausea
No vomiting
No headache
No eye wiggles
No jaw clenching
No muscle discomfort/tension
No diarrhea
Overall, I am amazed with the lack of side effects / hang over that this compound induced, and such a powerful and enjoyable experience it produced.

Real software, the kind working programmers produce by the kLOC to solve
real-world problems, tends to be “natural”, like speech or natural language; it
tends to be highly repetitive and predictable. Researchers have captured this
naturalness of software through statistical models and used them to good effect
in suggestion engines, porting tools, coding standards checkers, and idiom
miners. This suggests that code that appears improbable, or surprising, to a
good statistical language model is “unnatural” in some sense, and thus possibly
suspicious. In this paper, we investigate this hypothesis. We consider a large
corpus of bug fix commits (ca. 7,139), from 10 different Java projects, and
focus on its language statistics, evaluating the naturalness of buggy code and
the corresponding fixes. We find that code with bugs tends to be more entropic
(i.e. unnatural), becoming less so as bugs are fixed. Ordering files for
inspection by their average entropy yields cost-effectiveness scores comparable
to popular defect prediction methods. At a finer granularity, focusing on
highly entropic lines is similar in cost-effectiveness to some well-known
static bug finders (PMD, FindBugs) and ordering warnings from these bug finders
using an entropy measure improves the cost-effectiveness of inspecting code
implicated in warnings. This suggests that entropy may be a valid, simple way
to complement the effectiveness of PMD or FindBugs, and that search-based
bug-fixing methods may benefit from using entropy both for fault-localization
and searching for fixes.

Assertions in a program are believed to help with automated verification, code
understandability, maintainability, fault localization, and diagnosis, all eventually leading
to better software quality. Using a large dataset of assertions in C and C++ programs, we
confirmed this claim, i.e., methods with assertions do have significantly fewer defects. Assertions
also appear to play a positive role in collaborative software development, where many
programmers are working on the same method. We further characterized assertion usage along
process and product metrics. Such detailed characterization of assertions will help to predict
relevant locations of useful assertions and will improve code quality.

Changes in software development come in many forms. Some changes are frequent, idiomatic, or
repetitive (e.g. adding checks for nulls or logging important values) while others are unique.
We hypothesize that unique changes are different from the more common similar (or non-unique)
changes in important ways; they may require more expertise or represent code that is more complex
or prone to mistakes. As such, these unique changes are worthy of study. In this paper, we present a
definition of unique changes and provide a method for identifying them in software project history.
Based on the results of applying our technique on the Linux kernel and two large projects at
Microsoft, we present an empirical study of unique changes. We explore how prevalent unique changes
are and investigate where they occur along the architecture of the project. We further investigate
developers’ contribution towards uniqueness of changes. We also describe potential applications of
leveraging the uniqueness of change and implement two of those applications, evaluating the risk of
changes based on uniqueness and providing change recommendations for non-unique changes.

Using GitHub, we studied gender and tenure diversity in online
programming teams. Using the results of a survey and regression modeling of
GitHub data set comprising over 2 Million projects, we studied how diversity
relates to team productivity and turnover. We showed that both gender and
tenure diversity are positive and significant predictors of productivity. These
results can inform decision-making on all levels, leading to better outcomes in
recruiting and performance.

To investigate whether a programming language is the right tool for the job, I gathered a
very large data set from GitHub (728 projects, 63M lines of code, 29K authors, 1.5M commits,
in 17 languages). Using a mixed-methods approach, combining multiple regression modeling with
visualization and text analytics, I studied the effect of language features such as static v.s.
dynamic typing, strong v.s. weak typing on software quality. By triangulating findings from
different methods, and controlling for confounding effects such as code size, project age, and
contributors, I observed that a language design choice does have a significant, but modest
effect on software quality.

Nowadays in open software market, multiple software are available to users that provide
similar functionality. For example, there exists a pool of popular SSL/TLS libraries (e.g.,
OpenSSL, GnuTLS, NSS, CyaSSL, GnuTLS, PolarSSL, MatrixSSL, etc.) for securing network
connections from man-in-the-middle attacks. Certificate validation is a crucial part of
SSL/TLS connection setup. Though implemented differently, the certificate validation logic of
these different libraries should serve the same purpose, following the SSL/TLS protocol, i.e.
for a given certificate, all of the libraries should either accept or reject it. In
collaboration with security researchers at the University of Texas at Austin, we designed the
first large-scale framework for testing certificate validation logic in SSL/TLS
implementations. First, we generated millions of synthetic certificates by randomly mutating
parts of real certificates and thus induced unusual combinations of extensions and
constraints. A valid SSL implementation should be able to detect and reject the unusual
mutants. Next, using a differential testing framework, we checked whether one SSL/TLS
implementation accepts a certificate while another rejects the same certificate. We used such
discrepancies as an oracle for finding flaws in individual implementations. We uncovered 208
discrepancies between popular SSL/TLS implementations, many of them are caused by serious
security vulnerabilities.

In order to automatically detect copy-paste errors, I investigated: (1) What are the common
types of copy-paste errors? (2) How can they be automatically detected? By analyzing
the version histories of FreeBSD and Linux, I found five common types of copy-paste errors and
then leveraging this categorization I designed a two-stage analysis technique to detect and
characterize copy-paste errors. The first stage of the analysis, SPA, detects and categorizes
inconsistencies in repetitive changes based on a static control and data dependence analysis.
SPA successfully identifies copy-paste errors with 65% to 73% precision, an improvement by 14
to 17 percentage points with respect to previous tools. The second stage of the analysis,
SPA++, uses the inconsistencies computed by SPA to direct symbolic execution in order to
generate program behaviors that are impacted by the inconsistencies. SPA++ further compares
these program behaviors leveraging logical equivalence checking (implemented with z3 theorem
prover) and generates test inputs that exercise program paths containing the reported
inconsistencies. A case study shows that SPA++ can refine the results reported by SPA and help
developers analyze copy-paste inconsistencies. I collaborated with researchers from NASA for
this work.

In today’s software ecosystem, which is primarily governed by web, cloud, and mobile
technologies, APIs perform a key role to connect disparate software. Big players like
Google, FaceBook, Microsoft aggressively publish new APIs to accommodate new feature
requests, bugs fixes, and performance improvements. We investigated how such fast paced
API evolution affects the overall software ecosystem? Our study on Android API evolution
showed that the developers are hesitant to adopt fast evolving, unstable APIs. For
instance, while Android updates 115 APIs per month on average, clients adopt the new APIs
rather slowly, with a median lagging period of 16 months. Furthermore, client code with
new APIs is typically more defect prone than the ones without API adaptation. To the best
of my knowledge, this is the first work studying API adoption in a large software
ecosystem, and the study suggests how to promote API adoption and how to facilitate growth
of the overall ecosystems.

This paper empirically demonstrates that developers spend a significant amount of time and
effort in introducing similar features and bug-fixes in and across different projects.
This involves a significant amount of repeated work. To automatically identify the
repetitive changes, I designed Repertoire, an source code change analysis tool that
compares the edit contents and the corresponding operations of program patches to identify
similar changes, with 94% precision and 84% recall. Using Repertoire, I showed that
developers often introduce a significant amount of repeated changes within and across
projects. Most notably, repetitive changes among forked projects (different variants of an
existing project, e.g., FreeBSD, NetBSD and OpenBSD) incur significant duplicate work. In
each BSD release, on average, more than twelve thousand lines are ported from peer
projects, and more than 25% of active developers participate in cross-system porting in
each release.

To create a new variant of an existing project, developers often copy an existing
codebase and modify it. This process is called software forking. After forking software,
developers often port new features or bug fixes from peer projects. Repertoire analyzes
repeated work of cross-system porting among forked projects. It takes the version
histories as input and identifies ported edits by comparing the content of individual
patches. It also shows users the extent of ported edits, where and when the ported edits
occurred, which developers ported code from peer projects, and how long it takes for
patches to be ported.

A recent study finds that errors of omission are harder for programmers to detect than
errors of commission. While several change recommendation systems already exist to
prevent or reduce omission errors during software development, there have been very few
studies on why errors of omission occur in practice and how such errors could be
prevented. In order to understand the characteristics of omission errors, this paper
investigates a group of bugs that were fixed more than once in open source
projects—those bugs whose initial patches were later considered incomplete and to which
programmers applied supplementary patches.

GPUs are typically used for high-performance rendering or batch-oriented computations, but
not as general purpose compute-intensive tasks, such as brain-computer interfaces or file
system encryption. Current OS treats GPU as an I/O device as opposed to a general purpose
computational resource, like a CPU. To overcome this issue, we proposed PTask APIs, a new
set of OS abstractions. As part of this work, I ported EncFS, a FUSE based encrypted file
system for Linux, to CUDA framework such that it can use GPU for AES encryption and
decryption. Using PTask’s GPU scheduling mechanism, I showed that running EncFS on GPU over
CPU made a sequential read and write of a 200MB file 17% and 28% faster.

'Cowardly' thug walks into nursing home and batters gran, 84, for no reason
Patricia, 84, was left with horrific face, chest and arm injuries after the attack in Huon Park retirement complex, Sydney, Australia as police branded the assault 'cowardly'
by Matthew Dresch, https://www.mirror.co.uk/authors/matthew-dresch/A 'cowardly' thug beat an 84-year-old grandmother in a nursing home bedroom, leaving her with horrific injuries.
The attacker broke in through the Patricia's window and proceeded to bash her face, chest and arm.
The woman was left bloodied and bruised after the ordeal at Huon Park retirement complex, in Sydney, Australia, on Saturday.
Neighbours in the picturesque village were flabbergasted by the brutal assault, which left the victim and her family in a state of shock.
Local resident Chris Griffith reportedly said: "This is a very quiet village, one of the benefits of the place is that it's very secure, it is a concern for everyone."
According to Mail Online, Detective Chief Inspector Luke Spurr added: "'This is an absolutely appalling and cowardly act and let me reassure you these type of offences are uncommon and that police are doing everything in their power to fully investigate this matter and to locate the offender."
The suspect was apparently wearing a tie, shirt, trousers and a jacket when he set upon the pensioner.
Police described him as having a medium build, brown eyes, dark hair, aged between 30 and 50, around 180cm tall and of Asian or Indian appearance.

The grandfather-of-four, from Basingstoke, Hampshire, has been left with a badly bruised face and says he is now too afraid to venture out of his house at night, reports the Daily Star.
And he said he would love to ask his attackers: "Are you proud of yourselves, for attacking a pensioner?"

Like jMock, EasyMock is a dynamic mock object library for Java. What are the main differences between jMock and EasyMock?
EasyMock uses actual method calls to define expectations. EasyMock therefore works with an IDE's code completion and refactoring tools better than jMock.
mock.method1( a ); mockControl.playback();
mock.expects(once()).method("method1").with( eq(a) );
We have found that the use of strings in jMock is not a huge disadvantage, especially if you use an IDE that can apply refactorings to names in string constants. Often when doing TDD, the method named in an expectation will not yet be defined in any interface, and so code completion cannot be used. We have found that the flexibility allowed by the jMock API is better at reducing the work of refactoring than the use of direct method calls.
By default, EasyMock tests actual arguments for equality to expected
arguments using the equals
method. This can overspecify expected
behaviour and make tests brittle. Sometimes you want to ignore an argument or
want looser constraints upon an argument's value. EasyMock lets you change
the way that arguments are matched on a call-by-call basis, but the syntax is
awkward and same matcher applies to all arguments. There isn't a way
to specify a different matcher for different arguments to the same call.
mock.method1( a ); mock.method2( b1, b2 ); // cannot specify that we don't care about argument b2 mockControl.setReturnValue( method2Result ); mockControl.playback();
In contrast, jMock forces the user to specify exactly how each actual argument is matched against expectations. This means that expectations are more verbose but precisely and clearly specify the expected behaviour of the object. By precisely specifying expected behaviour you get flexible tests that break only when the actual behaviour is different from expected behaviour, and do not break when you make unrelated changes to application code.
mock.expects(once()).method("method1").with( eq(a) ); mock.expects(once()).method("method2").with( same(b1), ANYTHING ) .will(returnValue(method2Result));
jMock is a design tool not a testing tool. jMock's API is designed so that tests express the design intent of the programmer as clearly as possible and can later be read as specifications. In EasyMock's "record/playback" API, expectations are normal method invocations that do not read as specifications and constraints upon those invocations must be specified with separate API calls that duplicate information about the expected call and are harder to read than jMock's expectations.
The result of the previous two design goals is that jMock requires that the programmer writing a test be very explicit about what is and isn't expected. The "call-chain" API style makes expectations longer than EasyMock's terse "record/playback" style. We were surprised, however, to find that our users prefer all the extra typing that jMock forced them to do because the result helps them quickly understand what tests are specifying.
EasyMock only stubs methods that return values or throw exceptions. jMock lets you write custom stubs that can call back into the tested object or perform other side effects.
mock.expects(once()).method("collectIntoList").with( isA(List.class) ) .will(addListElement(element));
EasyMock lets the programmer specify that calls to a mock must occur in order, or occur in any order. There is no way to specify that call a should occur after call b but in any order compared to call c. There is no way to test the order of calls to different mock objects.
jMock lets the programmer specify partial ordering of invocations and specify the order of invocations on different mock objects.
EasyMock can be extended in a few ways by the user. However extensions do not cleanly integrate with the rest of the framework and extension points are quite limited. For example, you cannot extend the way that EasyMock stubs calls.
User extensions to jMock are used in exactly the same way as the built-in jMock constructs. This makes it easier to read tests, because unimportant details (whether a constraint is or is not an extension) are kept out of the code of test methods. jMock lets the user extend more aspects of the framework's behaviour.
jMock automatically verifies mock objects at the end of the test. It is easy to forget to verify all your mock objects and this can hide test failures. However, this means that...
To use jMock your test cases must extend MockObjectTestCase. This class performs automatic verification and provides the syntactic sugar that makes jMock tests easy to read.


Zone 2 - More Complex Privacy
If you are looking to keep yourself a little bit more secure than zone 1, this zone/method is for you! Here you will find more complex ways to keep your information safe from the rest of the internet.
Communication Texting is one unsafe way of communicating because it is not always secure, alternatives like Facebook Messenger or Instagram DM's are not good at keeping your data secure either. If you have aan apple device, stick to only using imessage, or use Signal(app) the most secure messenger. Signal is an open source and everything is fully encrypted where only you and the person you’re texting can view your messages. If you are an Android user, it can be set up as your default SMS. Your SmartphoneThe ongoing debate on which is better, Iphone or Android can be established today! Iphone is the most secure device while Android devices are more likely to get infiltrated because they do not get regular security updates. However, if you have a stock Android device it does get frequent updates and it is a much better option.
StorageYou need to periodically wipe your hard drives to free up space and you can do so by using a tool like CCleaner so you cannot recover any of the files you decide to delete. Another key element in storage is encryption, you should be using drive encryption and you should never remove the encryption from any device, especially android, if you are given the option to do so.
Your Web BrowserYou should avoid web browsers like chrome because Google has been known to collect your data. Web browsers like firefox or any other privacy based browser to keep your privacy secure. In terms of extension you should use an ad blocker such as uBlock Origin, a tracker blocker such as Privacy Badger, and HTTPS Everywhere to keep you using HTTPS instead of HTTP. Ensure flash and JavaScript are also disabled in your browser.


The installation will assume you have installed HTCondor v7.0.5+.
For the purposes of the examples shown here the HTCondor install location is
shown as /opt/glideincondor.
The working directory is
/opt/glidecondor/condor_local and the machine name is
mymachine.fnal.gov.
If you want to use a different setup, make the necessary changes.
If you installed HTCondor via RPMs the configuration files location is different: see
this OSG guide
or the OSG pages about the
Fronrtend
and Factory.
Multiple Schedds
Note: If you specified any of these options using the GlideinWMS configuration based installer, these files and initialization steps will already have been performed. These instructions are relevant to any post-installation changes you desire to make.
Unless explicity mentioned, all operations are to be done by the user that you installed HTCondor as.
Increase the number of available file descriptors
When using multiple schedds, you may want to consider increasing the available file descriptors. This can be done by issuing a "ulimit -n" command as well as changing the values in the /etc/security/limits.conf file
Using the condor_shared_port feature
The HTCondor shared_port_daemon is available in Condor 7.5.3+.
GlideinWMS V2.5.2+
Additional information on this daemon can be found here:-

HTCondor manual 3.7.2 Reducing Port Usage with the condor_shared_port Daemon
Your /opt/glidecondor/condor_config.d/02_gwms_schedds.config will need to contain the following attributes. Port 9615 is the default port for the schedds.
#-- Enable shared_port_daemonNote: Both the SCHEDD and SHADOW processes need to specify the shared port option is in effect.
SHADOW.USE_SHARED_PORT = True
SCHEDD.USE_SHARED_PORT = True

Multiple Schedds in GlideinWMS V2.5.2+
The following needs to be added to your Condor config file for each additional schedd desired. Note the numeric suffix used to distinguish each schedd.If the multiple schedds are being used on your WMS Collector, Condor-G is used to submit the glidein pilot jobs and the SCHEDD(GLIDEINS/JOBS)2_ENVIRONMENT attribute shown below is required. If not, then it should be omitted.
Effective with Condor 7.7.5+, the JOB_QUEUE_LOG attribute is required.
For the WMS Collector:
SCHEDDGLIDEINS2 = $(SCHEDD)
SCHEDDGLIDEINS2_ARGS = -local-name scheddglideins2

Multiple Schedds in GlideinWMS V2.5.1
Create setup files
If not already created during installation, you will need to create a set of files to support multiple schedds. This describes the steps necessary.
/opt/glidecondor/new_schedd_setup.sh
(example new_schedd_setup.sh)
1. adds the necessary attributes when the schedds are initialized and
started.
if [ $# -ne 1 ]
then
echo "ERROR: arg1 should be schedd name"
return 1
fi
LD=`condor_config_val LOCAL_DIR`
export _CONDOR_SCHEDD_NAME=schedd_$1
export _CONDOR_MASTER_NAME=${_CONDOR_SCHEDD_NAME}
# SCHEDD and MASTER names MUST be the same (Condor requirement)
export _CONDOR_DAEMON_LIST="MASTER, SCHEDD,QUILL"
export _CONDOR_LOCAL_DIR=$LD/$_CONDOR_SCHEDD_NAME
export _CONDOR_LOCK=$_CONDOR_LOCAL_DIR/lock
#-- condor_shared_port attributes ---
export _CONDOR_USE_SHARED_PORT=True
export _CONDOR_SHARED_PORT_DAEMON_AD_FILE=$LD/log/shared_port_ad
export _CONDOR_DAEMON_SOCKET_DIR=$LD/log/daemon_sock
#------------------------------------
unset LD
The same file can be downloaded from example-config/multi_schedd/new_schedd_setup.sh .
/opt/glidecondor/init_schedd.sh
(example init_schedd.sh)
1. This script creates the necessary directories and files for the additional schedds.
It will only be used to initialize a new secondary schedd.
(see the initialize schedds section)
#!/bin/sh2. This needs to be made executable by the user that installed Condor:
CONDOR_LOCATION=/opt/glidecondor
script=$CONDOR_LOCATION/new_schedd_setup.sh
source $script $1
if [ "$?" != "0" ];then
echo "ERROR in $script"
exit 1
fi
# add whatever other config you need
# create needed directories
$CONDOR_LOCATION/sbin/condor_init
chmod u+x /opt/glidecondor/init_schedd.shchmod a+x /opt/glidecondor/init_schedd.sh
The same file can be downloaded from example-config/multi_schedd/init_schedd.sh .
/opt/glidecondor/start_master_schedd.sh
(example start_master_schedd.sh)
1. This script is used to start the secondary schedds
(see the starting up schedds section)
#!/bin/sh2.- This needs to be made executable by the user that installed Condor:
CONDOR_LOCATION=/opt/glidecondor/condor-submit
export CONDOR_CONFIG=$CONDOR_LOCATION/etc/condor_config
source $CONDOR_LOCATION/new_schedd_setup.sh $1
# add whatever other config you need
$CONDOR_LOCATION/sbin/condor_master
chmod u+x /opt/glidecondor/start_master_schedd.shThe same file can be downloaded from example-config/multi_schedd/start_master_schedd.sh .
Initialize schedds
To initialize the secondary schedds, use /opt/glidecondor/init_schedd.sh created above.
If you came here from another document, make sure you configure the schedds specified there.
For example, supposing you want to create schedds named schedd_jobs1, schedd_jobs2 and schedd_glideins1, you would run:
/opt/glidecondor/init_schedd.sh jobs1
/opt/glidecondor/init_schedd.sh jobs2
/opt/glidecondor/init_schedd.sh glideins1
Starting up schedds
If you came to this document as part of another installation, go back and follow those instructions.
Else, when you are ready, you can start the schedd by running /opt/glidecondor/start_master_schedd.sh created above.
For example, supposing you want to start schedds named schedd_jobs1, schedd_jobs2 and schedd_glideins1, you would run:
/opt/glidecondor/start_master_schedd.sh jobs1Note: Always start them after you have started the Collector.
/opt/glidecondor/start_master_schedd.sh jobs2
/opt/glidecondor/start_master_schedd.sh glideins1
Submission and monitoring
The secondary schedds can be seen by issuing
condor_status -scheddTo submit or query a secondary schedd, you need to use the -name options, like:
condor_submit -name schedd_jobs1@ job.jdl
condor_q -name schedd_jobs1@
Multiple Collectors for Scalability
For scalability purposes, this section will describe the steps (configuration) necessary to add additional (secondary) HTCondor collectors for the WMS and/or User Collectors.
Note: If you specified any of these options using the GlideinWMS configuration based installer, these files and initialization steps will already have been performed. These instructions are relevant to any post-installation changes you desire to make.
Important: When secondary (additional) collectors are added to either the WMS Collector or User Collector, changes must also be made to the Frontend configurations so they are made aware of them.
HTCondor configuration changes
For each secondary collector, the following Condor attributes are required:
COLLECTORnn = $(COLLECTOR) COLLECTORnn_ENVIRONMENT = "_CONDOR_COLLECTOR_LOG=$(LOG)/CollectornnLog" COLLECTORnn_ARGS = -f -p port_number DAEMON_LIST = $(DAEMON_LIST), COLLECTORnn
In the above example, n is an arbitrary value to uniquely identify each secondary collector. Each secondary collector must also have a unique port_number.
After these changes have been made in your Condor configuration file, restart HTCondor to effect the change. You will see these collector processes running (example has 5 secondary collectors).

Multiple Collectors for High Availability (HA)
For reliability purposes, you may want to utilize Condor's High Availability (HA) feature for
collectors.
Note:This is only supported in glideinWMS for use with the User pool collector and frontend
with v2.6+.
Important: When the Condor High Availability feature is used in the User Collector, changes must also be made to the Frontend configurations so it is made aware of them.

If you want to use a different setup, make the necessary changes.
Unless explicity mentioned, all operations are to be done as root.
Obtain and install PostgreSQL RPMs
Most Linux distributions come with very old versions of PostgreSQL, so you will want to download the latest version.
The RPMs can be found on http://www.postgresql.org/ftp/binary/
At the time of writing, the latest version is v8.2.4, and the RPM files to install are
postgresql-8.2.4-1PGDG.i686.rpm
postgresql-libs-8.2.4-1PGDG.i686.rpm
postgresql-server-8.2.4-1PGDG.i686.rpm
Initialize PostgreSQL
Switch to user postgres:
su - postgresAnd initialize initialize the database with:
initdb -A "ident sameuser" -D /var/lib/pgsql/data
Configure PostgreSQL
PostgreSQL by default only accepts local connections., so you need to configure it in order for Quill to use it.
Please do it as user postgres.
To enable TCP/IP traffic, you need to change
listen_addresses in /var/lib/pgsql/data/postgresql.conf to:
# Make it listen to TCP ports
listen_addresses = '*'
Moreover, you need to specify which machines will be able to access it.
Unless you have strict security policies forbiding this, I recommend enabling
read access to the whole world by adding the following line
to /var/lib/pgsql/data/pg_hba.conf:
host all quillreader <IP_ADDRESS>/0 md5On the other hand, we want only the local machine to be able to write the database. So, we will add to /var/lib/pgsql/data/pg_hba.conf:
host all quillwriter <IP_ADDRESS>/32 md5
Start PostgreSQL
To start PostgreSQL, just run:/etc/init.d/postgresql startThere should be no error messages.
Initalize Quill users
Switch to user postgres:su - postgresAnd initialize initialize the Quill users with:
createuser quillreader --no-createdb --no-adduser --no-createrole --pwprompt
# passwd reader
createuser quillwriter --createdb --no-adduser --no-createrole --pwprompt
# password <writer passwd>
psql -c "REVOKE CREATE ON SCHEMA public FROM PUBLIC;"
psql -d template1 -c "REVOKE CREATE ON SCHEMA public FROM PUBLIC;"
psql -d template1 -c "GRANT CREATE ON SCHEMA public TO quillwriter; GRANT USAGE ON SCHEMA public TO quillwriter;"
Configure Condor
Append the following lines to /opt/glidecondor/etc/condor_config:#############################In /opt/glidecondor/condor_local/condor_config.local, add QUILL to DAEMON_LIST, getting something like:
# Quill settings
#############################
QUILL_ENABLED = TRUE
QUILL_NAME = quill@$(FULL_HOSTNAME)
QUILL_DB_NAME = $(HOSTNAME)
QUILL_DB_QUERY_PASSWORD = reader
QUILL_DB_IP_ADDR = $(HOSTNAME):5432
QUILL_MANAGE_VACUUM = TRUE
DAEMON_LIST = MASTER, QUILL, SCHEDDFinally, put the writer passwd into /opt/glidecondor/condor_local/spool/.quillwritepassword:
echo "<writer passwd>" > /opt/glidecondor/condor_local/spool/.quillwritepassword
chown condor /opt/glidecondor/condor_local/spool/.quillwritepassword
chmod go-rwx /opt/glidecondor/condor_local/spool/.quillwritepassword

17 SEPTEMBER 2009
Sometimes you reach a point with a Website where it gets difficult to properly style the site if you don’t have the right assets on your local machine. The database and the assets are always changing and growing due to user input.
You could alway download the latest assets, but sometimes there are to big to download or you just don’t want to keep the assets on your local machine.
One solution to this problem is to set up an Asset Host. You can easily add an Asset Host in the environments/development.rb
ActionController::Base.asset_host = "assets.example.com"
Every single asset comes from the assets.example.com
host. Thats fine, until you realize that the javascript and css files comes from the host too (Yes, it took me about 15 min to realize why my changes in the css didnt’t work ;).
So here is the solution for the problem:
ActionController::Base.asset_host = Proc.new { |source|
if source.starts_with?('/assets')
"gameone.de"
else
"http://localhost:3000"
end
}
I put the code in an initializers and ignored it from git.
initializers/config_local_asset_host.rb
if Rails.env == "development"
ActionController::Base.asset_host = Proc.new { |source|
if source.starts_with?('/assets')
"gameone.de"
else
"http://localhost:3000"
end
}
end

With forget my ex you can delete all your data related to your ex on facebook (or we redirect you to do that). We know that keeping that is annoying.
 Luckly not anymore!
But if by chance you come back dating, you can download all your data and readd to facebook.


Because headers are important
Before you begin building your page, you'll need to decide on a basic page layout. To do this, just sit down with some old-fashioned paper and a pencil and start sketching, blocking out the page's elements. You may be itching to get coding, but by drawing your site out first you can rearrange designs to your heart's content without having to code and recode.
Once you've settled on the organization of your site, it's time to begin creating your pages with HTML tags the instructions that surround material such as text, images, and links to other pages and tell the viewer's Web browser how to display them. If you want an image to show up on the left side of the page, a certain word to appear bold, or another word to link to an outside resource, you'll use HTML tags to do it.
There are five important rules for coding with HTML tags.
- Tags are always surrounded by angle brackets (less-than/greater-than characters), as in

. - Most tags come in pairs and surround the material they affect. They work like a light switch: the first tag turns the action on, and the second turns it off. (There are some exceptions. For instance, the

tag creates a blank line and doesn't have an "off switch." Once you've made a line break, you can't unmake it.) - The second tag the "off switch" always starts with a forward slash. For example, you turn on bold with

, shout your piece, and then go back to regular text with
. - First tag on, last tag off. Tags are embedded, so when you start a tag within another tag, you have to close that inner tag before closing the outer tag. For instance, the page will not display properly with the tags in this order:
<TITLE>
Your text</TITLE>
. The correct order is:<TITLE>
Your text</TITLE>
. - Many tags have optional attributes that use values to modify the tag's behavior. The

(paragraph) tag'sALIGN
attribute, for instance, lets you change the default (left) paragraph alignment. For example,

centers the next paragraph on the page.

Qt Quick Demo - Tweet Search
Tweet Search is a QML application that searches items posted to Twitter service using a number of query parameters. Search can be done for tweets from a specified user, a hashtag, or a search phrase.
The search result is a list of items showing the contents of the tweet as well as the name and image of the user who posted it. Hashtags, names and links in the content are clickable. Clicking on the image will flip the item to reveal more information.
Running the Example
To run the example from Qt Creator, open the Welcome mode and select the example from Examples. For more information, visit Building and Running an Example.
Tweet Search uses Twitter API v1.1 for running seaches.
Request Authentication
Each request must be authenticated on behalf of the application. For demonstration purposes, the application uses a hard-coded token for identifying itself to the Twitter service. However, this token is subject to rate limits for the number of requests as well as possible expiration.
If you are having authentication or rate limit problems running the demo, obtain a set of application-specific tokens (consumer key and consumer secret) by registering a new application on https://dev.twitter.com/apps.
Type in the two token values in TweetsModel.qml:
property string consumerKey : "" property string consumerSecret : ""
Rebuild and run the demo.
JSON Parsing
Search results are returned in JSON (JavaScript Object Notation) format. TweetsModel
uses an XMLHTTPRequest object to send an HTTP GET request, and calls JSON.parse() on the returned text string to convert it to a JavaScript object. Each object representing a tweet is then added to a ListModel:
var req = new XMLHttpRequest; req.open("GET", "https://api.twitter.com/1.1/search/tweets.json?from=" + from + "&count=10&q=" + encodePhrase(phrase)); req.setRequestHeader("Authorization", "Bearer " + bearerToken); req.onreadystatechange = function() { status = req.readyState; if (status === XMLHttpRequest.DONE) { var objectArray = JSON.parse(req.responseText); if (objectArray.errors !== undefined) console.log("Error fetching tweets: " + objectArray.errors[0].message) else { for (var key in objectArray.statuses) { var jsonObject = objectArray.statuses[key]; tweets.append(jsonObject); } } if (wasLoading == true) wrapper.isLoaded() } wasLoading = (status === XMLHttpRequest.LOADING); } req.send();

Section 4 Examining the confidence levels
As shown in the image above, the alert on the top of the page displays number of images matched and confidence levels for each class.
Note that because my face (one on the left) is only slightly shown, my friend's face (the one on the right) has confidence level of 1 because she has top 20 closest matches.
Section 5 Scaling the confidence values
Shown above is the code modification made to WebcamClassifier.js
Unlike the original code, the modified code now first finds a class with the most matches (let's call this number of matches "Max Match"). Then in the following iterations, we calculate the probabilities of each classes. If the number of matches is less than half of Max Match, the probability for the given class is 0. Otherwise, the probability is #matches / totalMatches. totalMatches equals to the total number of matches of all classes whose probability is greater than 0.
In both examples above, not only the classes with 0 match, but also classes with positive number of matches have probablity of 0. For example, in the top image, the first class has 5 matches, the second has 0, and the third has 15. In this case, the Max Match is 15, and both 5 and 0 are less than 7.5, the half of Max Match. Therefore the class with 15 matches has probability of 1, and the other two have probability of 0.
In the above two examples, there are two classes with positive probability in each scenario. For example in the bottom image, the Max Matches is 13. Thus, the first class, whose number of matches is 7, should also be factored in, as its number of matches is greater than the half of Max Match (6.5). Therefore the probabilities of the two qualifying classes are proportionally distributed.
Section 6 Limiting the number of training examples per class
Image above demonstrates the code modified for Section 6. As shown in the image, allocated number of samples are 10 for the first class, 100 for the second class, and 200 for the third class.
As shown in the image, an alert pops up when the maximum number of samples are collected.
Image above verifies that only 10 samples are collected for the first class, and only 100 samples are collected for the second class as specified in the code.
We noticed that when there is a large discrepancy in number of maximum samples for each classes, confidence level for the classes are slightly affected as well. We suspect that this is because number of top matches, which correlates with the probability and confidence level of the classes, significantly decreases if the number of total samples available decreases. I noticed that for classes with small sample size, adding more weight on matches can compensate the decreased confidence level.
Section 7 Further Explorations
For this section, we decreased the number of classes from 3 to 2. The image below shows the code modification for the change.
With such change, now the confidence level of each classes are modified. In the popup alert, the confidence levels are calculated for only the first two classes as shown below.


{% extends "main.html" %} {% block content %}
Well, that wasn't supposed to happen. Maybe try again? If it still doesn't work email me or leave a message on my steam profile.
Let me know the url of the page, where you were beforehand, and what you were doing. If you were submitting an item, the more details you can give me about the items being submitted the better (paints, particles, "I switched from genuine rarity to unique to strange", anything of the sort).
Also if you were logged in, you still are despite the sign-in button being back there again. Just move to a different page. Sorry for the confusion.


Working with Realms, Users, Groups, and Roles
You often need to protect resources to ensure that only authorized users have access. See Characteristics of Application Security for an introduction to the concepts of authentication, identification, and authorization.
This section discusses setting up users so that they can be correctly identified and either given access to protected resources or denied access if they are not authorized to access the protected resources. To authenticate a user, you need to follow these basic steps.
The application developer writes code to prompt for a user name and password. The various methods of authentication are discussed in Specifying Authentication Mechanisms.
The application developer communicates how to set up security for the deployed application by use of a metadata annotation or deployment descriptor. This step is discussed in Setting Up Security Roles.
The server administrator sets up authorized users and groups on the GlassFish Server. This is discussed in Managing Users and Groups on the GlassFish Server.
The application deployer maps the application’s security roles to users, groups, and principals defined on the GlassFish Server. This topic is discussed in Mapping Roles to Users and Groups.
What Are Realms, Users, Groups, and Roles?
A realm is a security policy domain defined for a web or application server. A realm contains a collection of users, who may or may not be assigned to a group. Managing users on the GlassFish Server is discussed in Managing Users and Groups on the GlassFish Server.
An application will often prompt for a user name and password before allowing access to a protected resource. After the user name and password have been entered, that information is passed to the server, which either authenticates the user and sends the protected resource or does not authenticate the user, in which case access to the protected resource is denied. This type of user authentication is discussed in Specifying an Authentication Mechanism in the Deployment Descriptor.
In some applications, authorized users are assigned to roles. In this situation, the role assigned to the user in the application must be mapped to a principal or group defined on the application server. Figure 39-6 shows this. More information on mapping roles to users and groups can be found in Setting Up Security Roles.
The following sections provide more information on realms, users, groups, and roles.
What Is a Realm?
The protected resources on a server can be partitioned into a set of protection spaces, each with its own authentication scheme and/or authorization database containing a collection of users and groups. A realm is a complete database of users and groups identified as valid users of one or more applications and controlled by the same authentication policy.
The Java EE server authentication service can govern users in multiple realms. The file, admin-realm, and certificate realms come preconfigured for the GlassFish Server.
In the file realm, the server stores user credentials locally in a file named keyfile. You can use the Administration Console to manage users in the file realm. When using the file realm, the server authentication service verifies user identity by checking the file realm. This realm is used for the authentication of all clients except for web browser clients that use HTTPS and certificates.
In the certificate realm, the server stores user credentials in a certificate database. When using the certificate realm, the server uses certificates with HTTPS to authenticate web clients. To verify the identity of a user in the certificate realm, the authentication service verifies an X.509 certificate. For step-by-step instructions for creating this type of certificate, see Working with Digital Certificates. The common name field of the X.509 certificate is used as the principal name.
The admin-realm is also a file realm and stores administrator user credentials locally in a file named admin-keyfile. You can use the Administration Console to manage users in this realm in the same way you manage users in the file realm. For more information, see Managing Users and Groups on the GlassFish Server.
What Is a User?
A user is an individual or application program identity that has been defined in the GlassFish Server. In a web application, a user can have associated with that identify a set of roles that entitle the user to access all resources protected by those roles. Users can be associated with a group.
A Java EE user is similar to an operating system user. Typically, both types of users represent people. However, these two types of users are not the same. The Java EE server authentication service has no knowledge of the user name and password you provide when you log in to the operating system. The Java EE server authentication service is not connected to the security mechanism of the operating system. The two security services manage users that belong to different realms.
What Is a Group?
A group is a set of authenticated users, classified by common traits, defined in the GlassFish Server. A Java EE user of the file realm can belong to a group on the GlassFish Server. (A user in the certificate realm cannot.) A group on the GlassFish Server is a category of users classified by common traits, such as job title or customer profile. For example, most customers of an e-commerce application might belong to the CUSTOMER group, but the big spenders would belong to the PREFERRED group. Categorizing users into groups makes it easier to control the access of large numbers of users.
A group on the GlassFish Server has a different scope from a role. A group is designated for the entire GlassFish Server, whereas a role is associated only with a specific application in the GlassFish Server.
What Is a Role?
A role is an abstract name for the permission to access a particular set of resources in an application. A role can be compared to a key that can open a lock. Many people might have a copy of the key. The lock doesn’t care who you are, only that you have the right key.
Some Other Terminology
The following terminology is also used to describe the security requirements of the Java EE platform:
Principal: An entity that can be authenticated by an authentication protocol in a security service that is deployed in an enterprise. A principal is identified by using a principal name and authenticated by using authentication data.
Security policy domain, also known as security domain or realm: A scope over which a common security policy is defined and enforced by the security administrator of the security service.
Security attributes: A set of attributes associated with every principal. The security attributes have many uses: for example, access to protected resources and auditing of users. Security attributes can be associated with a principal by an authentication protocol.
Credential: An object that contains or references security attributes used to authenticate a principal for Java EE services. A principal acquires a credential upon authentication or from another principal that allows its credential to be used.
Managing Users and Groups on the GlassFish Server
Follow these steps for managing users before you run the tutorial examples.
To Add Users to the GlassFish Server
- Start the GlassFish Server, if you haven’t already done so.
Information on starting the GlassFish Server is available in Starting and Stopping the GlassFish Server.
- Start the Administration Console, if you haven’t already done so.
To start the Administration Console, open a web browser and specify the URL http://localhost:4848/. If you changed the default Admin port during installation, type the correct port number in place of 4848.
- In the navigation tree, expand the Configurations node, then expand the server-config node.
- Expand the Security node.
- Expand the Realms node.
- Select the realm to which you are adding users.
- Select the file realm to add users you want to access applications running
in this realm.
For the example security applications, select the file realm.
The Edit Realm page opens.
- Select the admin-realm to add users you want to enable as system administrators
of the GlassFish Server.
The Edit Realm page opens.
You cannot add users to the certificate realm by using the Administration Console. In the certificate realm, you can add only certificates. For information on adding (importing) certificates to the certificate realm, see Adding Users to the Certificate Realm.
- Select the file realm to add users you want to access applications running
in this realm.
- On the Edit Realm page, click the Manage Users button.
The File Users or Admin Users page opens.
- On the File Users or Admin Users page, click New to add
a new user to the realm.
The New File Realm User page opens.
- Type values in the User ID, Group List, New Password, and Confirm New
Password fields.
For the Admin Realm, the Group List field is read-only, and the group name is asadmin. Restart the GlassFish Server and Administration Console after you add a user to the Admin Realm.
For more information on these properties, see Working with Realms, Users, Groups, and Roles.
For the example security applications, specify a user with any name and password you like, but make sure that the user is assigned to the group TutorialUser. The user name and password are case-sensitive. Keep a record of the user name and password for working with the examples later in this tutorial.
- Click OK to add this user to the realm, or click Cancel to quit without saving.
Setting Up Security Roles
When you design an enterprise bean or web component, you should always think about the kinds of users who will access the component. For example, a web application for a human resources department might have a different request URL for someone who has been assigned the role of DEPT_ADMIN than for someone who has been assigned the role of DIRECTOR. The DEPT_ADMIN role may let you view employee data, but the DIRECTOR role enables you to modify employee data, including salary data. Each of these security roles is an abstract logical grouping of users that is defined by the person who assembles the application. When an application is deployed, the deployer will map the roles to security identities in the operational environment, as shown in Figure 39-6.
For Java EE components, you define security roles using the @DeclareRoles and @RolesAllowed metadata annotations.
The following is an example of an application in which the role of DEPT-ADMIN is authorized for methods that review employee payroll data, and the role of DIRECTOR is authorized for methods that change employee payroll data.
The enterprise bean would be annotated as shown in the following code:
import javax.annotation.security.DeclareRoles; import javax.annotation.security.RolesAllowed; ... @DeclareRoles({"DEPT-ADMIN", "DIRECTOR"}) @Stateless public class PayrollBean implements Payroll { @Resource SessionContext ctx; @RolesAllowed("DEPT-ADMIN") public void reviewEmployeeInfo(EmplInfo info) { oldInfo = ... read from database; // ... } @RolesAllowed("DIRECTOR") public void updateEmployeeInfo(EmplInfo info) { newInfo = ... update database; // ... } ... }
For a servlet, you can use the @HttpConstraint annotation within the @ServletSecurity annotation to specify the roles that are allowed to access the servlet. For example, a servlet might be annotated as follows:
@WebServlet(name = "PayrollServlet", urlPatterns = {"/payroll"}) @ServletSecurity( @HttpConstraint(transportGuarantee = TransportGuarantee.CONFIDENTIAL, rolesAllowed = {"DEPT-ADMIN", "DIRECTOR"})) public class GreetingServlet extends HttpServlet {
These annotations are discussed in more detail in Specifying Security for Basic Authentication Using Annotations and Securing an Enterprise Bean Using Declarative Security.
After users have provided their login information and the application has declared what roles are authorized to access protected parts of an application, the next step is to map the security role to the name of a user, or principal.
Mapping Roles to Users and Groups
When you are developing a Java EE application, you don’t need to know what categories of users have been defined for the realm in which the application will be run. In the Java EE platform, the security architecture provides a mechanism for mapping the roles defined in the application to the users or groups defined in the runtime realm.
The role names used in the application are often the same as the group names defined on the GlassFish Server. Under these circumstances, you can enable a default principal-to-role mapping on the GlassFish Server by using the Administration Console. The task To Set Up Your System for Running the Security Examples explains how to do this. All the tutorial security examples use default principal-to-role mapping.
If the role names used in an application are not the same as the group names defined on the server, use the runtime deployment descriptor to specify the mapping. The following example demonstrates how to do this mapping in the glassfish-web.xml file, which is the file used for web applications:
<glassfish-web-app> ... <security-role-mapping> <role-name>Mascot</role-name> <principal-name>Duke</principal-name> </security-role-mapping> <security-role-mapping> <role-name>Admin</role-name> <group-name>Director</group-name> </security-role-mapping> ... </glassfish-web-app>
A role can be mapped to specific principals, specific groups, or both. The principal or group names must be valid principals or groups in the current default realm or in the realm specified in the login-config element. In this example, the role of Mascot used in the application is mapped to a principal, named Duke, that exists on the application server. Mapping a role to a specific principal is useful when the person occupying that role may change. For this application, you would need to modify only the runtime deployment descriptor rather than search and replace throughout the application for references to this principal.
Also in this example, the role of Admin is mapped to a group of users assigned the group name of Director. This is useful because the group of people authorized to access director-level administrative data has to be maintained only on the GlassFish Server. The application developer does not need to know who these people are, but only needs to define the group of people who will be given access to the information.
The role-name must match the role-name in the security-role element of the corresponding deployment descriptor or the role name defined in a @DeclareRoles annotation.

Hilbert transform.
y_h = hilberttrans(y)
This function computes the Hilbert transform of input vector y
and returns it in y_h
.
More precisely, y_h
actually computes the analytical signal from y
. The real part of y_h
contains the original signal y
, whereas the imaginary part of y_h
contains the Hilbert transform.
To obtain the dispersion of a Gaussian lineshape from the absorption form, use
x0 = 0; w = 0.1; x = linspace(-1,1,1000)*3; yabs = gaussian(x,x0,w); ydisp = hilberttrans(yabs); ydisp = imag(ydisp); plot(x,yabs,x,ydisp);
You can compare this to the dispersion that's directly provided by gaussian,
[yabs,ydisp0] = gaussian(x,x0,w); plot(x,ydisp,x,ydisp0);
