I feel this is an often overlooked Cave STG – a real gem. It happens to be one of my Cave favorites. So much fun and originality. Also, it plays perfectly on MiSTer FPGA (thank you so much @nullobject). (っ▀¯▀)つ

たまに見掛ける理論だけど、意味わからんよねそれ。 NullObject パターンとか NOP で空振りとかさせて流せってことなのかしら・・・？？

#Analogizer Tecmo core WIP based on Pocket @nullobject core.

When it comes to shmups, I believe FPGA is undoubtedly the best way to experience them nowadays. I’d love to ask @nullobject a few questions about the amazing work done with Cave—huge thanks in advance for your contributions to gaming preservation!

実装ってその人の好みが出る。 - Factoryの組み合わせてNull（何もしない）オブジェクトを返す人（NullObjectパターン） - IllegalArgumentExceptionを返す人 - 呼び出し前にチェックする人 - Null安全で担保する 後続の処理にどのように作用するかが関心事。 ｢機能的ビュー｣に分類。

nullじゃなくてNullObject

Building a chain of responsibility? It’s the real world, so we’ll wire it up with Symfony’s DI! Also, to reduce code duplication (and show off) we’ll throw in the NullObject pattern. buff.ly/3MrCycR

Yes, I agree that maybe my example with the ERB can be implemented in many other ways and 1-2-3-4 ifs are not a big deal. But combining NullObject Sorbet will make this pattern pretty useful in some specific cases and also remove a lot of problems people have with it when combined with a proper interface. Of course this was a specific solution I used and maybe my example with the ERB is not the best example of a "client thing" using the NullObject.

I put all of these in a short video showing how to implement a NullObject for an optional belong_to Active Record association in #Ruby on #Rails

Enter the scene NullObject defined by Bobby Woolf in a paper in 1996 And here is another quote from the same paper about when to use it

Recently I had to implement a NullObject for an optional belongs_to association in #Ruby on #Rails Let's assume the following models: Notice that the Account belong_to team is optional:

nullobject

в первом варианте не NullObject (объект уже есть, то что его свойства nullable вполне валидно)

ベースエンジンmodが動くと噂！！！！ だが俺は動かない！！！！！なぜ！！！！！！！ NullObject S H I N E

J'ai pas fait grand chose si ce n'est bidouiller un peu le contenu de ce beau repo github.com/nullobject/de0-na…, un chouille de refactoring et une adaptation du Cyclone IV du DE0-Nano vers une carte Cyclone II chinoise (genre ça : fr.aliexpress.com/item/10050…) Merci m'sieur nullobject !

I’m actually in camp „every nil check is a smell“, but will concede that not everything is solvable with a nice NullObject

Cat pawed Jaleco Pony Mk III with MiSTer running Puzzle Uo Poko. Thank you @MisterAddons and @nullobject, and thank you @EVAC_CORP 😽

Do you write this #Rails code? if current_user do do.. else do.. end You must watch @r00k's refactoring talk❤️from Aloha Ruby conf 2012. Among other amazing nuggets he proved how vital NullObject is to avoid nil👌🏽. aka, Replace condition with polymorphism youtu.be/DC-pQPq0acs?si=FVGJ…

Cave core. Think you need to be a Patreon of @nullobject to get it. Wonder how Josh is?!

ActiveRecordとかNullObject、GENERATIONS Gapはパターンとかそこら辺の古典。 アスペクト指向アーキテクチャ リソース指向アーキテクチャ オブジェクト指向アーキテクチャ オニオンアーキテクチャ クリーンアーキテクチャ レイヤードアーキテクチャ なんでも良いんだけど引き出しの広さは必要かと
