Display dates and times. Don&#39;t withhold information have from the user. Don&#39;t try to be clever.<br/><br/>Just saw an app tell me that a particular message was sent to me on Wednesday. Which Wednesday? In the time zone I am currently in, it&#39;s Wednesday. If the message was sent on Wednesday 3rd December, that is the information you give the user.<br/><br/>Even better, include the time. That way, people can more clearly see intervals and durations. 2025-12-09T22:05:03Z https://yabu.me/nevent1qqsdfqcrmymcwcgymhm57mnqwstt3v8gjp5d0xr3crmvcrnhle9622gzyqf7572sldj6z3xfv99jn6sqv9uvngtkvzf0a72fpnwujhw0fzah7sue52d Blogged: Step Back<br/><br/>&#34;Instead of trying harder, do the opposite.

I haven&#39;t come across definitive studies on this, but just rummaging around it seems that where typical rates across the industry for developers are around 5–20 defects / KLOC, with AI-generated code is around an order of magnitude higher. 2025-08-25T09:17:33Z https://yabu.me/nevent1qqs02pf03pgmx09uxmejvhcdy245khgpm2nk7lcwu8tc2jkkz07wxagzyqf7572sldj6z3xfv99jn6sqv9uvngtkvzf0a72fpnwujhw0fzah7sqnfwc If you&#39;re interested in having me speak, run some training, consult, etc., please get in touch. There is a small chance I may be able to fit you in this year, but things are pretty booked up. Better to get in touch now for something early to middle of next year than leave it until the last minute. 2025-08-18T16:15:52Z https://yabu.me/nevent1qqs0p9v68j7e2rxfwv903tfq26sd7qp5wvgrkj2yddxjpm7sy9wwsgszyqf7572sldj6z3xfv99jn6sqv9uvngtkvzf0a72fpnwujhw0fzah7fvlev2 There are lots of principles that vie for developers&#39; attention, some of which are arbitrary (e.g., SOLID), some of which are misleading (e.g., SRP), or misunderstood (e.g., DRY, Separation of Concerns), some of which are redundant (e.g., ISP) and some of which are just plain wrong (e.g., OCP), but there are some that are classic, timeless, effective and, unfortunately, still ignored.<br/><br/>In this category we find the balanced pairing of high cohesion and low coupling. 2025-08-11T08:46:04Z https://yabu.me/nevent1qqsz2zwg804q4cj2q8ha0vddhc6ns25kpj05pp28l2qae5ags5enydqzyqf7572sldj6z3xfv99jn6sqv9uvngtkvzf0a72fpnwujhw0fzah7yxfmth It&#39;s not even funny how so many are fawning over &#39;modular monoliths&#39; as if they&#39;re some great new idea and alternative to microservices.<br/><br/>Consequently, I&#39;m proposing a new conference talk for later this year: Modular Monoliths and Other Facepalms. 2025-08-07T06:26:04Z https://yabu.me/nevent1qqsz3rve2vwt8eera2kyk905t2fxdeupe89utd40ye3x7xy0e6nqjlszyqf7572sldj6z3xfv99jn6sqv9uvngtkvzf0a72fpnwujhw0fzah74u7qkf One of my constant frustrations with many apps (web and mobile) is the constant need to confirm via OTPs, 2FA, etc., that I am indeed me when I&#39;m in the same session for which I&#39;ve already just done this less than a minute earlier. <br/><br/>Security — as opposed to security theatre — requires a more joined-up approach to architecture. This kind of annoyance highlights potential problems of organisational structure and process in the development organisation, unmanaged technical debt, etc. 2025-07-31T07:58:55Z https://yabu.me/nevent1qqsqdparagvgzcnfaqlmnz56k8sz4mks9440a7d4lxhat2fyfz77j6szyqf7572sldj6z3xfv99jn6sqv9uvngtkvzf0a72fpnwujhw0fzah7zg06v5 So why do we prioritize things like feature development and bug fixes in software development?

I can live with the latter, but the former is a continual source of frustration.<br/><br/>Does anyone know of any serious proposals to improve lambdas, such as allow them to hold statements? 2025-07-10T10:57:41Z https://yabu.me/nevent1qqspplvgxmpmt38dfepwmghlrlv3h7kqh2pqy2xj5lszh3jrq2hekkczyqf7572sldj6z3xfv99jn6sqv9uvngtkvzf0a72fpnwujhw0fzah7rv8t9m Tell me you don&#39;t know what reading is without telling me you don&#39;t know what reading is<br/><br/> <img src="https://files.mastodon.social/media_attachments/files/114/822/608/167/265/049/original/ad01b5e27d5e50ef.png"> 2025-07-09T09:39:42Z https://yabu.me/nevent1qqsqyludjav8yr3hv50s2vr3dwhy0qn7hnn6wmarkv5asudylnyxhxczyqf7572sldj6z3xfv99jn6sqv9uvngtkvzf0a72fpnwujhw0fzah7kwzs5f To understand how effectively people currently use and will use AI one can look at two previous transformative technologies: the spreadsheet and the search engine.<br/><br/>The first point is, of course, that they have been transformative. There was a definite &#39;before&#39; and &#39;after&#39; for individuals and businesses.<br/><br/>They have been effective. That does not, however, mean their widespread adoption has meant they have been used effectively, and the way these products have evolved has also been suboptimal. 2025-07-03T09:22:33Z https://yabu.me/nevent1qqs9s9kscv9sdjy4hyefwdjz8z4tqesjqudrfpln9plh5sjuyj09x7szyqf7572sldj6z3xfv99jn6sqv9uvngtkvzf0a72fpnwujhw0fzah7auzsad Watching a speaker apologise for any quirks in the code they&#39;re using in their slides.<br/><br/>&#34;It was generated by AI.&#34;<br/><br/>Resisted the temptation to raise my hand and say, &#34;You know you&#39;re allowed to edit generated code before committing it?&#34;<br/><br/>Don&#39;t use LLMs to increase the unmanaged technical debt in the world.
