I wrote a thing after some recent hedge fund closures:

@davidfowl What are these "tests" you speak of?

[dale.holborow @HolborowDale]

@JeffWeniger Mmmm... stock value... or stock price?

[dale.holborow @HolborowDale]

@xoofx one absurdly nitpicking reply.. your logo truncates/obscures when viewed on a mobile phone... which ruins the landing experience :D

@buccocapital After trying to walk my highly intelligent but non-nerd friend thru buying a domain last week, I'm not convinced that everyone is going to suddenly vibe code their own websites just yet

[dale.holborow @HolborowDale]

@evantindell And the wisdom to know the difference?

[dale.holborow @HolborowDale]

@hkeskiva I owned this for a while attracted to incredible ROE etc, but exited (too late). Latest figure okay, but long term, its been good but nothing truly great (src morningstar)

@Floebertus @jackschwager I'm on holiday and away from my book collection but from memory, didn't a large percentage of the featured investors subsequently go broke and/or get convicted of criminal activity and fraud?

@Aaronontheweb Ah so Polly isn't necessarily on your list of software sins, just not a good fit here? Team mate introduced me to it a while ago on a gig where a tonne of clunky manual retry logic was easily replaced with Polly calls so I grew fond of it

[dale.holborow @HolborowDale]

@Aaronontheweb Two things: why not Polly ? And, is this useful for your url parsing needs? https://t.co/whnd2Kd5uJ

[dale.holborow @HolborowDale]

@JeffWeniger Do you have data further back, out of curiosity (you wrote over last generation, wondering has something structural changed over this past 15 years, or did it hold prior as well)?

[dale.holborow @HolborowDale]

New milestone so new release to celebrate! I finally got around to bringing my C# Url Detection lib to 1-to-1-parity with the original LinkedIn lib. Includes minor perf enhancements, suite of benchmarks, general cleanup and linting. Get it here https://t.co/whnd2Kd5uJ

[dale.holborow @HolborowDale]

@BillBrewsterTBB Upon *reflection... Sigh. But yeah.

[dale.holborow @HolborowDale]

@Aaronontheweb @EricRichards22 Wasn't that the same CEO who claimed they were freezing hiring precisely because of AI, back when it was trendy about 12 months ago (IBM, Klarna etc)

[dale.holborow @HolborowDale]

@TidefallCapital Where did you get that 1.3 trillion figure for Jan? I use FINRA site but don't see Jan released yet, would love more timely data source if one exists?

[dale.holborow @HolborowDale]

@jerriepelser I use MVC & often declare duplicate action routes so a post will survive a page refresh (by having the same path declared as a GET equivalent), will this support that? It looks like not as controller method names themselves r the generated elements & can't have dupe names?

[dale.holborow @HolborowDale]

@jerriepelser Quick peak and that looks very cool, will take it for a spin. Thanks!

[dale.holborow @HolborowDale]

@Aaronontheweb So for code where you're subsequently persisting a value object to a db , do you tend to use assignment overrides, to copy EmailAddress valobj to string Email, for example?

[dale.holborow @HolborowDale]

@1MainCapital @pmje73 Learned this the hard way, in the volatile post-Corona markets... Bought what still mostly looks like great quality/growth, but I often heavily overpaid. Expensive lesson
