Fighters controlled by artificial intelligence and a living person met for the first time in a training air battle in the skies over the United States. However, DARPA did not say which of them “won.”
The first battle between the AI and the pilot took place back in 2021, and then the car won almost all the battles, but that was on a simulator. Now the real VISTA X-62A fighter was under AI control. In the skies above Edwards Air Force Base, he engaged in close combat with an F-16 aircraft piloted by pilots.
There was also an instructor in the cockpit of the VISTA X-62A and the AI, but he did not touch the control levers - the artificial intelligence independently built the order of defensive and offensive maneuvers. During a training battle, the planes even performed a rendezvous maneuver of up to 600 m at a speed of about 2000 km/h.

Top 8 Cache Eviction Strategies. 👇👇👇👇👇 ➖➖➖➖➖➖➖➖ 🕊 @gopher_academy | @GolangEngineers
op 8 Cache Eviction Strategies.
.
.
🔹 LRU (Least Recently Used)
LRU eviction strategy removes the least recently accessed items first. This approach is based on the principle that items accessed recently are more likely to be accessed again in the near future.
🔹 MRU (Most Recently Used)
Contrary to LRU, the MRU algorithm removes the most recently used items first. This strategy can be useful in scenarios where the most recently accessed items are less likely to be accessed again soon.
🔹 SLRU (Segmented LRU)
SLRU divides the cache into two segments: a probationary segment and a protected segment. New items are initially placed into the probationary segment. If an item in the probationary segment is accessed again, it is promoted to the protected segment.
🔹 LFU (Least Frequently Used)
LFU algorithm evicts the items with the lowest access frequency.
🔹 FIFO (First In First Out)
FIFO is one of the simplest caching strategies, where the cache behaves in a queue-like manner, evicting the oldest items first, regardless of their access patterns or frequency.
🔹 TTL (Time-to-Live)
While not strictly an eviction algorithm, TTL is a strategy where each cache item is given a specific lifespan.
🔹 Two-Tiered Caching
In Two-Tiered Caching strategy, we use an in-memory cache for the first layer and a distributed cache for the second layer.
🔹 RR (Random Replacement)
Random Replacement algorithm randomly selects a cache item and evicts it to make space for new items. This method is also simple to implement and does not require tracking access patterns or frequencies.

#روتکیت
وقتی یه نرم افزاری (یه Process) روی یه سیستم عامل ران میشه (حالا چه ویندوز باشه، چه لینوکس باشه، چه اندروید باشه و ...)؛ یه سری دسترسی های خاص خودش رو داره
دسترسی هایی که یه Process میتونه داشته باشه، کاملا بستگی داره به اون یوزری که اون پروسز رو استارت کرده
بطور مثال، اگه شما یه پروسز رو با یوزر عادی سیستمتون استارت کنید، منطقا خودش به تنهایی دسترسی پاک کردن فایل های سیستمی مهم و یا دستکاری رجیستری سیستم رو نداره (مثلا وقتی میبینین میخواین یه installer رو باز کنین، ازتون اجازه ی ادمین میخواد. چون میخواد به رجیستری دسترسی پیدا کنه)
حالا روت کیت چیه؟ به یه ابزاری گفته میشه (که معمولا بصورت غیر مجاز، با استفاده از باگ ها و vulnerability های سیستم)، یکاری میکنه که پروسزی که با یه یوزر عادی ران میشه، دسترسی ادمین (روت) بگیره.
برای تست امنیت سیستم عامل (و نرم افزار های مختلف مثل sudo) هم خیلی استفاده داره.
