It recommends project rules, clean commit checkpoints, explicit test requirements, read-only planning, scoped instruction files, documented AI context, and protected tests to make changes safer, more consistent, and easier to review or revert. ### Source excerpt TL;DR: Install your harness before prompting: the structure you set up first is what turns an impulsive AI into a safe, steerable collaborator. Common Mistake ❌ You open a fresh chat and type a bare ## Explore Angular Router's runGuardsAndResolvers DevFeed: [Explore Angular Router's runGuardsAndResolvers]() Original publisher: [Read original article]() Published: 2019-01-31T00:00:00Z Content type: tutorial Language: en Sources: [Juri Strumpflohner]() Topics: [Angular](), [Framework]() Tags: [angular](), [configuration](), [guards](), [resolvers](), [route](), [router](), [state]() ### AI overview This tutorial explains Angular Router's runGuardsAndResolvers configuration and the options introduced in Angular 7.1 and 7.2. It describes when route guards and resolvers run based on path parameters, query parameters, URL changes, and a custom function. ### Source excerpt Lorem ipsum dolor sit amet ## Learn Angular Router for Real-World Applications DevFeed: [Learn Angular Router for Real-World Applications]() Original publisher: [Read original article]() Published: 2018-12-05T00:00:00Z Content type: tutorial Language: en Sources: [Juri Strumpflohner]() Topics: [Angular](), [Routing (disambiguation)](), [App]() Tags: [angular](), [guards](), [lazy-loading](), [performance-tuning](), [router](), [rxjs](), [video]() ### AI overview An announcement for a two-part Egghead video course that teaches the Angular router, beginning with an approximately 60-minute introduction. The course covers routing concepts, route configuration, child routes, routing modules, URL segments, RxJS Observables, route guards, and lazy loading. ### Source excerpt Lorem ipsum dolor sit amet ## Install on Home Screen DevFeed: [Install on Home Screen]() Original publisher: [Read original article]() Author: Shai Almog Published: 2018-12-03T00:00:00Z Content type: tutorial Language: en Sources: [CodeName One]() Topics: [PWA](), [Web](), [Mobile]() Tags: [browser](), [guards](), [hints](), [install](), [mobile](), [pwa](), [screen](), [web](), [web-apps]() ### AI overview This tutorial explains how Progressive Web Apps can be installed on a device home screen. It discusses the need for explicit browser installation prompts because desktop, mobile, and web platforms behave differently, and notes that the prompt is shown only once to avoid duplicate prompts. ### Source excerpt We talked about our support for Progressive Web Apps before. We added quite a few enhancements since that support was introduced and it's a pretty powerful feature. Personally I consider it a killer feature, even if Google decides to ban your account you can still distribute your app. One of the cool features is the seamlessness. Most of the functionality "just works". However, there are some cases where we need explicit hints due to the different behavior of desktop/mobile and web. ## Better Redirects in Angular Route Guards DevFeed: [Better Redirects in Angular Route Guards]() Original publisher: [Read original article]() Published: 2018-11-28T00:00:00Z Content type: tutorial Language: en Sources: [Juri Strumpflohner]() Topics: [Angular](), [Authorization](), [User experience (UX)](), [Data structures]() Tags: [angular](), [async](), [blocking](), [bugfixes](), [data-structure](), [features](), [guards](), [implementation](), [object](), [route](), [router](), [state](), [view]() ### AI overview This tutorial explains Angular 7.1 route guard improvements, focusing on returning an UrlTree to redirect users when a route cannot be activated. It also distinguishes client-side route guards as a UX feature from server-side security checks. ### Source excerpt Lorem ipsum dolor sit amet ## Intentional Optionality DevFeed: [Intentional Optionality]() Original publisher: [Read original article]() Author: Steve Barnegren Published: 2018-09-13T00:00:00Z Content type: tutorial Language: en Sources: [Steve Barnegren]() Topics: [Swift](), [Code]() Tags: [code](), [guards](), [let](), [optional](), [swift]() ### AI overview A Swift article examines intentional use of optionality. It argues that while non-optional types are usually preferable, optional values can sometimes make code easier to read and understand, including when handling leaderboard entries and conditional menu items. ### Source excerpt When I first started writing Swift, I felt like Optionals were a constant pain point. Everything seemed to end up being Optional, resulting in me littering if lets and guards around my code, and generally just making a horrible mess of things. ## Foobar, Blossoms, and Isomorphism DevFeed: [Foobar, Blossoms, and Isomorphism]() Original publisher: [Read original article]() Author: yifanlu Published: 2017-09-13T07:00:00Z Content type: tutorial Language: en Sources: [Yifan Lu]() Topics: [Programming](), [Code](), [Google]() Tags: [algorithm](), [computer-science](), [foobar](), [google](), [guards](), [latex](), [math](), [number-theory](), [programming](), [technical]() ### AI overview A detailed solution to Google Foobar's "Distract the Guards" problem. The article models when two guards enter an infinite loop and explains how maximum matching can pair the greatest possible number of guards into such loops. ### Source excerpt A friend recently invited me to participate in Foobar, Google's recruiting tool that lets you solve interesting (and sometimes not-so-interesting) programming problems. This particular problem, titled "Distract the Guards" was very fun to solve but I found no good write-ups about it online! Solutions exist but it is rather hard to understand how the author came upon the solution. I thought I might take a shot and go into detail into how I approached it-as well as give proofs of correctness as needed.
