Say I had a Windows application, #cpp that runs inside the console, that does some inconceivably (to me) complex math on structured input data, then generates a corresponding output.
It’s mine but I didn’t write it, and don’t have the source code. But I do have an incredibly detailed article written by the author, that describes the math involved and optimisations to make it run, which I couldn’t begin to understand or explain.
What are the chances of finding someone to recreate it in #js ?

@ulisse62 mi domando anche io cosa si aspetti a rendersi conto che i sistemi informatici non possono essere allegramente appartati a terzi, magari di potenze straniere, per non aver la seccatura di (a) dover istruire una generazione a saperli creare, gestire, difendere e (b) appunto difenderli come asset strategici!

@lgeurts true, analysis paralysis can be a heavy burden

New level of content laziness encountered - why not *include the prompt you gave the AI* at the start of the article, as well as the slop generated content itself 🤦

@Mohammedjhad Amazing idea, Mohammed! 🙂❤️

@derSammler those are good examples of Ball Grid Array and Land Grid Array, e.g. BGA and LGA cores. The BGA page has examples of many sub-types, and links to the other primary designs, kinda worth a look:

There's so much fun to be had with old CPU collections, especially vintage alternate types like the Alpha. Sun UltraSparc and PowerPC from the same era also have some beautiful examples.
That DS15 CPU is a classic (https://en.m.wikipedia.org/wiki/Alpha_21264), very interesting early example of using branch prediction calculations to accelerate cache reads vs suffering potential cycle penalties and stack eviction.
> The predictor was used as the Alpha 21264 has a minimum branch misprediction penalty of seven cycles. Due to the instruction cache's two cycle latency and the instruction queues, the average branch misprediction penalty is 11 cycles. The algorithm maintains two history tables, Local and Global...
> The local predictor consists of a 1,024-entry by 10-bit branch history table... Each entry is a 3-bit saturating counter. The value of the counter determines whether the current branch is taken or not taken.
> The global predictor is a single-level, 4096-entry branch history table. Each entry is a 2-bit saturating counter; the value of this counter determines whether the current branch is taken or not taken.
ok ok, enough of this nerdery. there are Alpha 21264 CPUs on eBay if anyone wants to own a piece of this wonderful engineering. https://ebay.us/m/ttryzO
