It explains how defining business objectives and measurable outcomes establishes viability, while testing ideas early and iterating helps assess feasibility and reduce risk. ### Source excerpt Updated 7/25/2025. Originally published 12/10/2024 Ambiguity in design isn't a roadblock -- it's an opportunity. Design ingenuity thrives in the gray area where rules haven't been written, and solutions are waiting to be discovered. So how do you turn "I have no idea where to start" into breakthrough ideas that actually work? At 8th Light, our approach is anchored in the three pillars of human-centered design: viability, feasibility, and desirability. These are the tools that transform chaos into clarity and make ambiguity your ally, not your enemy. Viability: Define Your Destination Before Picking the Route The truth is, you don't need to know the "how" right away. However, you absolutely need to know the "why." Viability ensures your team stays aligned with business objectives, reducing costly detours and keeping your efforts focused on delivering measurable value. Picture this: You're tasked with fixing an outdated customer onboarding process. The details are vague, but the goal is crystal clear -- reduce the time it takes for new users to find value. Once you've mastered the "why," the rest becomes an experiment. Early setbacks are simply data points, guiding you toward smarter decisions. Viability keeps you aligned with business objectives, ensuring that every test and rapid iteration thereafter, serves a purpose. Pro tip: Start every ambiguous project with these two questions: What are we trying to achieve? Why does this matter? -> Takeaway: Before starting a project, define clear business objectives and measurable outcomes. Use these as your north star to guide every decision. Feasibility: Stop Guessing, Start Testing With your goals in place, it's time to embrace the unknown and start experimenting. Feasibility minimizes risk by validating ideas early, reducing the chance of expensive missteps, and accelerating your path to market-ready solutions, encouraging you to iterate effectively to reach the solution. It answers the question: Can we actually build this? ## Make regular expressions easier to read DevFeed: [Make regular expressions easier to read]() Original publisher: [Read original article]() Author: Stanko Published: 2025-03-31T00:00:00Z Content type: tutorial Language: en Sources: [Stanko Tadić]() Topics: [Code](), [formatting](), [Maintainability]() Tags: [example](), [extra](), [join](), [maintainability](), [readability](), [regular-expressions](), [value]() ### AI overview The article presents a formatting technique for making complex regular expressions easier to read: split the expression into multiple string components, join them, and construct the final regex. The approach adds code and requires escaping backslashes, but enables scanning and comments that can improve readability and maintainability. ### Source excerpt This is a simple formatting trick I use to make regular expressions more readable. The secret? Break them into multiple lines. To achieve this, format the regex as an array of strings and then concatenate the array into a single regex string. Example # Compare this example, written in a single line: const FILTER_REGEXP = /(?blur|brightness|contrast|grayscale|hue-rotate|invert|opacity|saturate|sepia)\((?-?\d*(?:\.\d*)?)(?\w*?)\)/g; with the multi-line version: const SUPPORTED_FILTERS = [ 'blur', 'brightness', 'contrast', 'grayscale', 'hue-rotate', 'invert', 'opacity', 'saturate', 'sepia', ].join('|'); const FILTER_REGEXP = new RegExp( [ `(?${SUPPORTED_FILTERS})`, // filter name `\\(`, `(?\-?\\d*(?:\\.\\d*)?)`, // value `(?\\w*?)`, // unit if any `\\)`, ].join(''), 'g' ); The multi-line version has a bit more code, but it's easier to scan and read. It also allows us to write comments for each section, clarifying the purpose of each part of the regex. I've found that complex expressions are much easier to write this way. I believe it greatly reduces the cognitive load for both the writer and the reader. Caveats # You'll need to escape the backslashes in regex strings. While this is a minor inconvenience, the readability benefits easily outweigh it. Conclusion # It boils down to personal preference, but I believe the extra code is worth it, as it improves readability and maintainability. This is especially true when dealing with notoriously difficult-to-parse complex regular expressions. ## Engineers Should Take Responsibility for Bugs in AI-Generated Code DevFeed: [Engineers Should Take Responsibility for Bugs in AI-Generated Code]() Original publisher: [Read original article]() Published: 2024-09-24T00:00:00Z Content type: opinion Language: en Sources: [Tim Kellogg]() Topics: [Artificial Intelligence](), [bug](), [Git](), [coding](), [trust]() Tags: [ai](), [autonomous](), [bug](), [code](), [coding](), [commit](), [git](), [junior](), [management](), [manager](), [solve](), [support](), [team](), [testing](), [trust](), [value]() ### AI overview This opinion article argues that engineers remain accountable for bugs in code generated with AI.

It also covers initializing a CSS variable early to reduce layout shift and briefly mentions a CSS alternative. ### Source excerpt Some operating systems and browsers are not showing scrollbars by default. That often results in developers forgetting about these pesky gray bars and the issues they can cause. I'll give you two quick examples: When setting overflow: hidden on the body element, if there was a scrollbar visible, content will jump a little as it now has more space. If you ever implemented scroll locking for modals, you've probably encountered this issue. Another thing is that width: 100vw and width: 100% on the body element don't match if there is a scrollbar visible: 100vw is the width of the viewport including the scrollbar. 100% is the width of the viewport excluding the scrollbar. This becomes obvious if you have a fixed element like a header. It will be a little bit wider than the rest of the content when scrollbar is visible. I'm sure there are more issues, but these are the two I remembered on top of my head. Anyhow, let's see how to solve this. JavaScript solution # Ideally we would like to have a scrollbar-width event. It doesn't exist, so we'll have to create a custom event ourselves, and trigger it when scrollbar width changes. To catch the width changing, we can't use the resize event because viewport size don't change when scrollbar is toggled. However, if we set the ResizeObserver on the html element, it will trigger when the scrollbar is toggled. Code # After setting the observer we need to fire our custom event when width has changed. Code looks something like this: const initScrollbarWidthEvent = () => { // Custom event const scrollbarEvent = new Event("scrollbar-width"); // Initial state let currentWidth = window.innerWidth - document.documentElement.clientWidth; const observer = new ResizeObserver(() => { const newWidth = window.innerWidth - document.documentElement.clientWidth; // Check if the scrollbar width has changed and trigger the custom event if (newWidth !== currentWidth) { // Update event data // We are passing both previous and current width, // because ## Introducing the Fermyon Cloud Key Value Store DevFeed: [Introducing the Fermyon Cloud Key Value Store]() Original publisher: [Read original article]() Author: The Fermyon Team Published: 2023-04-18T07:00:00Z Content type: release Language: en Sources: [Fermyon - Experience the next wave of cloud computing.]() Topics: [Cloud](), [Serverless](), [data]() Tags: [application](), [cloud](), [data](), [key-value-store](), [serverless](), [store](), [value]() ### AI overview Fermyon introduces a Cloud Key Value Store for persisting non-relational data in a key/value store for serverless applications. The store is described as always available within milliseconds and having no cold starts. ### Source excerpt With the introduction of the Fermyon Cloud Key Value Store, you can now persist non-relational data in a key/value store that is always available for your serverless application within milliseconds, with no cold starts. ## SharedFlow and StateFlow DevFeed: [SharedFlow and StateFlow]() Original publisher: [Read original article]() Published: 2022-02-21T00:00:00Z Content type: tutorial Language: en Sources: [Kt.

It examines EOF in Unix I/O, its usual value of -1, and why that value cannot represent a character. ### Source excerpt I was reading Computer Systems: A Programmer's Perspective the other day and in the chapter on Unix I/O the authors mention that there is no explicit "EOF character" at the end of a file. ## Value-Based Pricing and TDD DevFeed: [Value-Based Pricing and TDD]() Original publisher: [Read original article]() Author: Bruce Eckel Published: 2020-02-09T00:00:00Z Content type: opinion Language: en Sources: [Bruce Eckel - Computing Thoughts]() Topics: [Test-driven development](), [Development]() Tags: [pricing](), [tdd](), [value]() ### AI overview The article examines value-based pricing and its relationship to Test-Driven Development. It argues that financial incentives can encourage clever thinking, while also emphasizing non-financial motivations such as reducing tedium, improving quality, and quality of life. ### Source excerpt I first heard about value-based pricing from an accountant who was creating a startup based on the idea. He tells a story about consulting for a family who inherited an estate. Because of the accountant's extensive knowledge, he was able to give advice that saved the family a million or more. However, he only charged for his time, a couple of hours. To save that amount, the story goes, the family would have been happy to pay more, an amount based on the value of the work rather than the time it took. ## localStorage and sessionStorage in Safari's private mode DevFeed: [localStorage and sessionStorage in Safari's private mode]() Original publisher: [Read original article]() Author: Stanko Published: 2017-08-09T00:00:00Z Content type: tutorial Language: en Sources: [Stanko Tadić]() Topics: [LocalStorage](), [Code](), [App]() Tags: [code](), [error](), [export](), [ls](), [null](), [object](), [qa](), [quota](), [return](), [safari](), [storage](), [test](), [value](), [version]() ### AI overview This article explains that Safari private mode sets localStorage and sessionStorage limits to zero, preventing writes. It presents a localStorage facade that silently ignores storage operations when storage is unavailable, avoiding application errors. ### Source excerpt If you didn't know, in Safari's private mode both localStorage and sessionStorage are not working. To be exact, Safari sets storage's limit to 0, so you can't write anything to it. I keep forgetting this, until QA people report it at some point. So I quickly wrote a small facade for it, which fails silently in this case. That means it still doesn't work but it won't throw an error and break your application. This is the version for localStorage, just replace it with sessionStorage if you need it. const LS_TEST_KEY = 'ls-test'; let isLocalStorageSupported = typeof localStorage === 'object'; // Try to try { localStorage.setItem(LS_TEST_KEY, 'test'); localStorage.removeItem(LS_TEST_KEY); } catch (e) { isLocalStorageSupported = false; // If we get error that we exceeded storage's quota // but storage is still empty we are in private mode if (e.code === DOMException.QUOTA_EXCEEDED_ERR && localStorage.length === 0) { // Private mode } else { throw e; } } const LocalStorage = { getItem: (key) => { if (isLocalStorageSupported) { return localStorage.getItem(key); } return null; }, setItem: (key, value) => { if (isLocalStorageSupported) { localStorage.setItem(key, value); } }, removeItem: (key) => { if (isLocalStorageSupported) { localStorage.removeItem(key); } }, }; export default LocalStorage; ## Preventing Google from Indexing Staging Sites DevFeed: [Preventing Google from Indexing Staging Sites]() Original publisher: [Read original article]() Author: andrew@nystudio107.com (Andrew Welch) Published: 2017-02-02T09:00:00Z Content type: tutorial Language: en Sources: [nystudio107 | Articles on modern web development.]() Topics: [Search engine optimization (SEO)](), [Crawler](), [Content Management System](), [Web Development]() Tags: [config](), [diluting](), [environments](), [google](), [indexing](), [insights](), [multi-environment](), [prevent](), [robots-txt](), [seo](), [seomatic](), [sites](), [staging](), [value]() ### AI overview This tutorial explains how to prevent Google and other search engines from indexing staging sites.

To do binding, the procedure is two steps. Since WinJS doesn't support two way bindings we need to define each one way binding. The first from source data to the destination and is done via WinJS.Binding.defaultBind. The second from the binding target back to the source data (in this case actually just from the input text box to the source model is done from an onchange event wiring. WinJS.Namespace.define("Binding.Mode", { twoway: WinJS.Binding.initializer(function (source, sourceProps, dest, destProps) { WinJS.Binding.defaultBind(source, sourceProps, dest, destProps); dest.onchange = function () { var d = dest[destProps[0]]; var s = source[sourceProps[0]]; if (s !== d) source[sourceProps[0]] = d; } }) }); ) Original publisher: [Read original article]() Published: 2012-11-10T00:00:00Z Content type: article Language: en Sources: [Radek Pazdera]() Topics: [C](), [Linux Kernel](), [container](), [Compiler](), [standard]() Tags: [c](), [compiler](), [container](), [implementation](), [library](), [linux-kernel](), [standard](), [standard-library](), [value]() ### AI overview This tutorial explains how the Linux Kernel's container_of() macro derives a pointer to a containing structure from a pointer to one of its members.

They emphasize that execution matters more than the idea and that differentiation can make market entry easier. ### Source excerpt I have a tendency of really latching onto very simple ideas. Typically these ideas don't require complex engineering to make them happen. This is not to say the engineering is not important, but more so that it is some variation of engineering feats that have been done before. The reason I tend to like these over more complex engineering that really makes something better is that making something better is typically a marginal improvement. When it's a marginal improvement it's a lot harder to sell. With marginal improvements you have to: In contrast if I address a problem that hasn't been solved my life instantly becomes a lot easier. I no longer have an argument of something not being good enough today, it becomes a question of value and how much its worth to solve the problem. Haggling over price is a conversation I'd rather have than trying to justify value and convince a customer they've been wrong in their choice for so many years. Over the coming days I'm going to be posting a few of these examples/ideas and why I like them. Many of them are still being thought through, and while as I sort them out, I'm generally happy to publish high points about them. The even bigger key here is that success is typically in the execution and less so in the idea, though even then I'd prefer to execute on something that has less battles than something that from the onset has more. By doing something that is being done today you get no advantages of penetrating the market. ## The benefit of leverage DevFeed: [The benefit of leverage]() Original publisher: [Read original article]() Author: Map Published: 2009-05-24T03:13:53Z Content type: opinion Language: en Sources: [Craig Kerstiens]() Topics: [Job](), [X (Twitter)]() Tags: [benefit](), [business](), [hiring](), [job](), [leverage](), [offer](), [value]() ### AI overview The article argues that employees often need leverage to negotiate fair compensation or treatment, especially when they can demonstrate valuable revenue potential, specialized internal knowledge, or credible outside opportunities. It also notes that relying on leverage undermines the fairness of the employment relationship. ### Source excerpt Due to many recent events, which I'm sure I'll disclose later, I've been in an interesting situation of a good bit of leverage. While leverage can of course be taken advantage of and misused, it also plays a very fair role in business. When hiring a new college graduate in most cases you take the offer you are given, some are able to negotiate for a higher salary, but most are quite unsuccessful. This is because they don't have any leverage. If you ended up walking away from the job offer they would simply hire another college graduate. While yes you may have a lot of potential, it's only that potential and not proven. Additionally within a corporation, the company will often do just enough to keep an employee there. If a company does a great job, an employee gets a pat on the back. If an employee is indispensable (though no company will ever admit to this), they may get a noticeable reward, but it still doesn't usually cover the value the individual is actually providing. This responsibility to get what you are truly worth usually lies with the employee. The hard part of this, is knowing when and how to use your leverage. First you must actually have leverage, this commonly in potential revenue you would bring in, or internal knowledge that you may have. Though I'm sure others have varying experiences, mine have been to make your dissatisfaction with a situation known, but in a light manner. Meanwhile make it visible that you're open to other opportunities as they may come along, this can be via twitter, blog post, or water cooler talk. The final thing, and hopefully this is an easier one, is make it clear that you have the leverage, the sale should be a big one, or the internal knowledge should be costly should they lose it. The most unfortunate part of all of this is that, in my experiences the leverage is typically needed to get a fair deal. And the single point of requiring leverage no longer makes it fair, but at least knowing this ensures you're not left out [Next page]()
