The DOS memory management functions check the signature of each MCB they work with. If it’s not ‘M’ or ‘Z’, an error is reported–and if that happens, all bets are off because something in the system corrupted memory, and nothing can be trusted anymore.
上週，中國解放軍在中國農曆新年期間開赴西太平洋展開大規模軍事演習，出動一艘航母以及數十艘艦艇與戰機。《紐約時報》一篇分析文章指出，在這次演習之前，美國近幾週才與日本、澳洲、菲律賓等盟國在該區域舉行一系列軍演。上周六，美加海軍艦隊更駛過台灣海峽。中國的演習明顯帶有對美日等盟國的回擊意味。。PDF资料是该领域的重要参考

Since the initial release, community contributions have pushed data efficiency from ~2.4x to 5.5x against modded-nanogpt, more than doubling in a few days. The key changes are: shuffling at the start of each epoch, which had outsized impact on multi-epoch training; learned projections for value embeddings instead of separate embedding tables; swapping squared ReLU for SwiGLU activation; and ensembling multiple models. 10x data efficiency seems reachable in the short term. 100x might be feasible by the end of the year, given how many directions remain unexplored, but it will require serious exploration on the algorithms side.，详情可参考91视频
There are likely several reasons for this strategic shift. The most obvious one is the poor sales performance of PS5 games on PC, with ports generally not arriving on Steam until at least a year after their console launch. This is in stark contrast with Microsoft, which will launch first-party titles such as Fable and Forza Horizon 6 on Xbox, PC and PS5 at the same time later this year. It would see Sony return to a more Nintendo-like approach, with the latter famously (and extremely successfully) holding firm on console exclusivity for the likes of Mario, Zelda and Pokémon.
