After an app UI change, replace the shared asset once; each page can keep its own crop, frame, and composition instead of being rebuilt by hand.08 Sep 2026 09:03 +0000at://did:plc:luvphwj635aoh53nga7knv2l/app.bsky.feed.post/3muyo3jl2m225https://bsky.app/profile/grunersoftware.bsky.social/post/3muw4ovitqs2hA saved development command is more than a shell string. Its working directory, execution target, recent output, and place in the project are part of its meaning. The command may be `npm run dev`, but the surrounding context is what makes it safely reusable.07 Sep 2026 08:47 +0000at://did:plc:luvphwj635aoh53nga7knv2l/app.bsky.feed.post/3muw4ovitqs2hhttps://bsky.app/profile/grunersoftware.bsky.social/post/3muto364sps2rI turned Apple's current App Store screenshot requirements into one sourced table covering iPhone, iPad, Mac, Apple TV, Vision Pro, and Watch.

A useful comparison works at the sheet and cell level: address, stored value, and whether it was added, removed, or changed. That is also how I make cross-format comparisons such as XLSX against ODS useful.06 Sep 2026 08:59 +0000at://did:plc:luvphwj635aoh53nga7knv2l/app.bsky.feed.post/3mutmw5n7ok27https://bsky.app/profile/grunersoftware.bsky.social/post/3muohh4k7yk2wDevDock 1.3 is live on the Microsoft Store. Git work is now safer inside each project: protect local changes while switching branches, see ahead/behind state, review push destinations, handle pull-before-push, and find commands faster. https://martingruner.com/blog/devdock-1-304 Sep 2026 07:38 +0000at://did:plc:luvphwj635aoh53nga7knv2l/app.bsky.feed.post/3muohh4k7yk2whttps://bsky.app/profile/grunersoftware.bsky.social/post/3mum7sfbk2k2mBuilding in an established category is not necessarily a disadvantage. People already understand the problem. The real question is whether an awkward workflow is still underserved. With Diff Anything, I’m focusing on local spreadsheet comparison across formats, without converting both sides first.03 Sep 2026 10:16 +0000at://did:plc:luvphwj635aoh53nga7knv2l/app.bsky.feed.post/3mum7sfbk2k2mhttps://bsky.app/profile/grunersoftware.bsky.social/post/3mujfjvzlgc2sWhen a tool says it supports PDF or spreadsheets, ask what it actually compares: bytes, structure, rendered output, or user-visible values. Those models answer different questions. The same files can be equal in one and different in another.02 Sep 2026 07:20 +0000at://did:plc:luvphwj635aoh53nga7knv2l/app.bsky.feed.post/3mujfjvzlgc2shttps://bsky.app/profile/grunersoftware.bsky.social/post/3muhcj5lxvs2cOne lesson from building desktop software: never hide the intermediate state. For a compare, sync, export, or migration workflow, show the plan before it runs. Let people cancel it. Make failure recoverable. Automation earns trust when the user can still see and control what it is doing.01 Sep 2026 11:21 +0000at://did:plc:luvphwj635aoh53nga7knv2l/app.bsky.feed.post/3muhcj5lxvs2chttps://bsky.app/profile/grunersoftware.bsky.social/post/3muh256n66s24Diff Anything 1.4 expands archive comparison.
