React JS Tutorial - #14 Error Handling
 
13:38
Following up on the previous video where we validated the form before passing its input to the countdown, we'd now want to provide visual feedback to the user as to whether the input was deemed valid or not. With Bulma, we can easily toggle helper classes to change the styling of our datepicker, as well as render additional text messages. Lastly, let's also refactor the form, such that the user input will be instantaneously validated and reflected in the UI on each keystroke.

Angular httpclient error handling
 
12:07
In this video we will discuss error handling in Angular. When using HttpClient, to call a server side service, errors may occur. When they do occur we want to handle these errors. Text version of the video http://csharp-video-tutorials.blogspot.com/2018/07/angular-httpclient-error-handling.html Slides http://csharp-video-tutorials.blogspot.com/2018/07/angular-httpclient-error-handling-slides.html Angular CRUD Tutorial https://www.youtube.com/playlist?list=PL6n9fhu94yhXwcl3a6rIfAI7QmGYIkfK5 Angular CRUD Tutorial Text Articles & Slides http://csharp-video-tutorials.blogspot.com/2017/12/angular-crud-tutorial.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists When an Angular component needs data, there are usually 3 players 1. The Component itself 2. The Angular Service and 3. The Server Side Service The first question that comes to our mind is, should we handle the service related errors in the service itself or in the component that consumes the service. According to Angular style guide, error inspection, interpretation, and resolution is something you want to do in the service, not in the component. If all goes well the server side service provides data to the client side angular service and the Angular service provides it to the component, which then displays that data to the user. However, sometimes the request may fail on the server or on the client. There are two types of errors that can occur. The server may reject the request, returning an HTTP response with a status code such as 404 or 500. These are error responses. Something could go wrong on the client-side such as a network error that prevents the request from completing successfully or an exception thrown in an RxJS operator. These errors produce JavaScript ErrorEvent objects. The HttpClient captures both kinds of errors in its HttpErrorResponse and you can inspect that response to figure out what really happened. So, the important point to keep in mind is, if the HttpErrorResponse is an instance of ErrorEvent, then it means that a client-side or network error occurred. If it's not an instance of ErrorEvent, then it means a server error occured. Displaying the actual raw errors to the end user is bad for two reasons - First they are cryptic and does not make much sense to the end user and second they may contain sensitive information that could be useful for a potential hacker. That is why we are logging the actual error and returning a user friendly error message. Finally, take the Observables returned by the HttpClient methods and pipe them through to the error handler. With the release of rxjs version 5.5, we have Pipeable Operators that can be used along with the pipe() function. Before the introduction of pipeable operators, we used to chain operators as shown below. So the point that I am, trying to make is 1. There are 2 types of operators in rxjs - Pipeable Operators and Patch Operators 2. Pipeable Operators are imported from rxjs/operators/ 3. Patch Operators are imported from rxjs/add/operator/ 4. Pipeable Operators have several benefits over Patch Operators. So if you have rxjs version 5.5 or later use pipeable operators. 5. Use the following link to read the benefits of pipeable operators https://github.com/ReactiveX/rxjs/blob/master/doc/pipeable-operators.md In our case, the angular service getEmployees() method is consumed by a Resolver service, and this resolver service provides the data to the LIST route. If there is an exception, the resolver fails and the target route, in our case the LIST route will not be activated. If a component is directly consuming the angular service getEmployees() method, then it is easy to catch the error observable and display the error message to the user. However, when a resolver is involved, the target route is not activated if there is an error. So displaying an error message to the end user is a bit more involved. In our next video, we will discuss handling errors and displaying error messages where there is a resolver between an angular service and the component.

Thomas Aglassinger - Solution oriented error handling
 
28:19
Thomas Aglassinger - Solution oriented error handling [EuroPython 2014] [22 July 2014] This talk shows how to use Python's built in error handling mechanisms to keep the productive code clean, derive error messages helpful for the user directly from the code and release ressources properly. ----- Traditionally error handling is regarded an annoyance by developers because it removes the focus from the already difficult enough productive parts of the code to parts that ideally will never be called. And even if, end users seem to be ignore the error messages and just click "Ok" or call the help desk. Solution oriented error handling uses Python's existing try/catch/finally idiom, with statement, assert statement and exception hierarchy in a way that keeps the code clean and easy to maintain. It gives a clear distinction between errors that can be solved by the end user, the system administrator and the developer. Naming conventions and a simple set of coding guidelines ensure that helpful error messages can be easily derived from the code. Most code examples work with Python 2.6+ and Python 3.x, on a few occasions minor differences are pointed out. Topics covered are: 1. Introduction to error handling in Python - What are errors? - How to represent errors in Python - Detecting errors - Delegating errors to the caller - clean resource management 2. Principles of solution oriented error handling - responsibilities between user, admin and developer - when to use raise or assert 3. Error messages - What are "good" error messages - How to derive error messages from the source code - Adding context to the error - How to report errors to the user 4. Solution oriented usage of Python's exception hierarchy - admins fix `EnvironmentError` - users fix `DataError` - representing `DataError` - converting exceptions to `DataError` - developers fix everything else - special Python exceptions not representing errors 5. Template for a solution oriented command line application 6. Best practices for `raise` and `except` - When to use `raise`? - When to use `except`? This talk is a translation of a German [talk](https://github.com/roskakori/talks/tree/master/pygraz/errorhandling) given at the PyGRAZ user group and in a (slightly depythonized variant) the Grazer Linux Tag 2013 ([slides and video](http://glt13-programm.linuxtage.at/events/198.de.html)).

Expect the Expected (aka Writing Error Resilient Code)
 
48:35
Writing code that is resilient upon errors has always been a pain point in all languages. Exceptions are the politically correct means to signal errors in C++, but many applications still resort to error codes for reasons related to ease of understanding, ease of handling errors locally, and efficiency of generated code. This talk shows how a variety of theoretical and practical artifacts can be combined together to address error codes and exceptions in one wholesome, simple package. The generic type expected<T> can be used for both local (error-code-style) and centralized (exception-style) manners, drawing from the strengths of each.

scale.bythebay.io: Haeley Yao, Error Handling Without Throwing Exceptions
 
17:44
In a microservice environment, it is painful to handle exceptions thrown by external services. We designed a mechanism for type-safe error handling using EitherT monad transformer to stack Future and Either. Calls to external services are implemented in a stack of EitherT for fail-fast error handling. Errors are separated for each logical external services. Error hierarchy is defined to expose different layers of the system. Location and reason of an error are provided for debugging. In addition, we validated input to each call of external service by Validated to accumulate errors. Validation rules are tested by property-based testing with ScalaCheck. We implemented both fail-fast and accumulated error handling with Cats in payment service for shopbot. Haeley Yao Software Engineer, eBay Haeley is a software engineer at eBay who works on building human assistant shopping bot and a shopping app targeted at Chinese customers, using Scala, Cats and microservice-based architecture. Haeley is interested in applying pure FP in large enterprise applications.

I advise taking a break half way through if you have a short attention span like me ;) Link the the GitHub project - https://github.com/Tosker/ValidationInWPF ** Tip Jar ** Paypal: [email protected] BTC: 3DkvwvcQ8Vt2U84jdtEhNBx2Ueai3Xttmu ETH: 0xFf79A145e1ED6F538607Ec374968e605cbea758b BCH: qqpgrnzuhc5hav4e79m8nfhmugs46jtl0ujxcu0tj5 LTC: MHXQmJA3hkwTPeArB9QPNkcLiHQx723yMb

How Browsers Handle Errors in CSS – 3/7 Resilient CSS
 
07:30
How do you write CSS that works in every browser? Step 1: Rely on the error handling model of CSS itself. CSS and HTML are declarative programming languages, which makes them much more resilient to problems. Rely on this quality to write code that always work, no matter how old the browser is. Jen shows you how, with an example using border radius.

CppCon 2016: Patrice Roy “The Exception Situation"
 
58:42
http://CppCon.org — Presentation Slides, PDFs, Source Code and other presenter materials are available at: https://github.com/cppcon/cppcon2016 — Exceptions have been a part of C++ for a long time now, and they are not going away. They allow programmers to concentrate on the meaningful parts of their code and treat the things that happen infrequently as… well, exceptional situations, to be dealt with when and where the context makes it reasonable or useful. On the other hand, some significant parts of the C++ programming community either dislike this mechanism or outright reject it, for a number of reasons. Work in SG14 has raised performance issues in some cases; there are those who dislike the additional execution paths introduced in programs that rely on exceptions; some programmers raised issues with respect to exceptions and tooling, integration with older codebases, writing robust generic code, etc. This talk will be neither for not against exceptions. It will present a perspective on cases where they make sense, cases where they are less appropriate, alternative disappointment handling techniques presented along with client code in order to show how the various approaches influence the way code is written. Performance measurements will be given along the way. Some creative uses of exceptions will also be presented in order to spark ideas and discussions in the room. — Patrice Roy Université de Sherbrooke Professor Sherbrooke (Québec), Canada Patrice Roy has been playing with C++, either professionally, for pleasure or (most of the time) both for over 20 years. After a few years doing R&D and working on military flight simulators, he moved on to academics and has been teaching computer science since 1998. Since 2005, he’s been involved more specifically in helping graduate students and professionals from the fields of real-time systems and game programming develop the skills they need to face today’s challenges. The rapid evolution of C++ in recent years has made his job even more enjoyable. He’s been a participating member in the ISO C++ Standards Committee since late 2014 and has been involved with the ISO Programming Language Vulnerabilities since late 2015.

In this talk I'll compare and contrast the approaches to functional error handling taken by Scalaz and Scalactic. I'll look at how different opinions on typeclass coherence led to two classes in Scalaz, \/ and Validation, and just one in Scalactic, Or. I'll explain why when it comes to success values, I feel left is right and right is wrong, whereas the Scalazzi think the opposite. I'll show how the libraries use algebraic structures differently. And I'll explore how different opinions on how best to leverage functional programming (FP) in Scala led to different library designs.

CppCon 2018: James McNellis “Unwinding the Stack: Exploring How C++ Exceptions Work on Windows”
 
01:06:26
http://CppCon.org — Presentation Slides, PDFs, Source Code and other presenter materials are available at: https://github.com/CppCon/CppCon2018 — If you’re writing modern C++ code, then it’s likely that you are using exceptions—whether you’re throwing them yourself or just using library code that might throw (e.g., std::vector). Have you ever stopped to think about how exceptions work under the hood? What actually happens at runtime when you throw an exception? How is the right catch statement found? In this session, we’ll explore how C++ exceptions actually work in the Visual C++ implementation on Windows. This session will discuss: * A very, very brief overview of how exceptions work in the C++ language * The code and data structures the Visual C++ compiler generates to facilitate proper stack unwinding * Exactly what happens when an exception is thrown, how the right catch statement is found, and how the stack is unwound * Structured Exception Handling (SEH), the Windows OS feature atop which C++ exceptions are built * How the Visual C++ runtime library interacts with the OS during stack unwinding * Interoperation with non-C++ exceptions, like hardware exceptions * How termination handling works when no matching catch statement is found or when a noexcept boundary is reached * How things differ on different architectures (x86 is very different from x64 and ARM!) This information can be very useful when debugging tricky problems—especially during postmortem debugging when you’re trying to figure out what went wrong before a program crashed—and we’ll highlight particular pieces of information that are most useful. — James McNellis, Microsoft Corporation Principal Software Engineer James McNellis is a Principal Software Engineer at Microsoft where he works on the Time Travel Debugging (TTD) reverse debugging toolkit. Prior to joining the Windows Debuggers team in 2016, he worked on the Visual C++ team and was responsible for the Microsoft C Runtime (CRT) and C Standard Library implementation. Passionate about all things related to C++, he is a frequent speaker at C++ conferences around the world and is a former top contributor on StackOverflow. — Videos Filmed & Edited by Bash Films: http://www.BashFilms.com

SBTB 2015: Long Cao, Evolving Your Code: More Functional Error Handling in Scala
 
21:24
There are many ways to approach error handling in Scala, some of which will look more familiar to those coming from Java backgrounds, and some that are more familiar to those coming from the FP side. In this talk, we'll explore refactoring your error handling code from Java-like Scala to a more functional style. We'll also take a brief look at some of the already existing constructs for functional error handling in the Scala ecosystem. Long is a software engineer at MediaMath in New York City and has been doing full time Scala development for the last 3 years. Prior to MediaMath he was an engineer writing Scala at Pellucid Analytics and Gawker Media, and hails from the great state of Texas. When not coding, he can be found indulging in coffee, beer, or both kinds of football. ---------------------------------------------------------------------------------------------------------------------------------------- Scalæ By the Bay 2016 conference http://scala.bythebay.io -- is held on November 11-13, 2016 at Twitter, San Francisco, to share the best practices in building data pipelines with three tracks: * Functional and Type-safe Programming * Reactive Microservices and Streaming Architectures * Data Pipelines for Machine Learning and AI

CppCon 2018: Andrei Alexandrescu “Expect the expected”
 
58:58
http://CppCon.org — Presentation Slides, PDFs, Source Code and other presenter materials are available at: https://github.com/CppCon/CppCon2018 — Writing code that is resilient upon errors has always been a pain point in all languages. Exceptions are the politically correct means to signal errors in C++, but many applications still resort to error codes for reasons related to ease of understanding, ease of handling errors locally, and efficiency of generated code. This talk shows how a variety of theoretical and practical artifacts can be combined together to address error codes and exceptions in one wholesome, simple package. The generic type expected<T> can be used for both local (error-code-style) and centralized (exception-style) manners, drawing from the strengths of each. — Andrei Alexandrescu, The D Language Foundation Vice President Andrei Alexandrescu is a researcher, software engineer, and author. He wrote three best-selling books on programming (Modern C++ Design, C++ Coding Standards, and The D Programming Language) and numerous articles and papers on wide-ranging topics from programming to language design to Machine Learning to Natural Language Processing.

Improved error handling with NITE skeletal tracking algorithms
 
00:26
I flail around like an idiot some more, in order to demonstrate better handling and detection of error cases. This demonstrates extrapolation of joints and their momentum, in order to prevent (in that input from NITE is ignored and filled in via extrapolation, until the situation is remedied) or smooth over errors in the core NITE tracking.

It works perfectly in a lot of cases; the only problem is that sometimes you just can't let it fall — maybe you want to present errors in a more handy way, or maybe you want to do something when your computation fails. In this talk different ways of error handling will be considered, in particular "straightforward" monadic approach of Erlando and more idiomatic one of z_validate library."
