    PRTG Catches Network Issues Before They Cause Downtime

    Threshold-based alerts flag problems early, so your team can act before users notice, not after.

    Reactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.

    ByFly GTA: SA GangWar
    Недолго думая я взялся делать мод в жанре TDM: копию мода того сервера, на котором я начинал играть. Рад представить вам возрождение мода ByFly GTA: SA GangWar. Важные примечания 1. Сервер на файлах 2. ЛАМО (двуручное оружие) запрещено 3. Никаких систем доната, vip, покупок админки и прочего В целом, подойдёт для основы. По коду: стиль везде практически одинаков, с табуляцией проблем нет. Новичкам, думаю, будет понятен. Античиты самые основные на мой взгляд. Зависимости Для работы мода требуются: mxINI (https://github.com/Open-GTO/mxINI) GetVehicleColor (https://pastebin.com/CS5X1C96) Все нужные библиотеки в архиве с модом. Благодарности Magic_York за советы и помощь Magic_York, Andrew_York, TheHero, HeavenX, Eduard_Stream, Zoopi, Unisheld, KailloN за помощь в тесте За основу был взят мод Los Santos Gang Wars by LethaL

    Charlotte's Utilities

    Charlotte's Utilities mod for Minecraft Forge made by Sharshar

    Charlotte's Utilities is my first adventure into modding Minecraft. I wanted to have some extra utilities and things for my server that I couldn't find in other mods, or if I could I was able to think of a different way that I would prefer to implement them. At its core, this mod pack is just a collection of utilities that I feel improve the game experience. Everything is fully configurable in the config file so you can change, enable, or disable whatever you feel is best for you! The mod has quickly developed into one that's aimed primarily at the builders of the Minecraft community, and I plan to expand on that idea going into the future. My goal is to provide new, unique, and easy ways to allow players to construct whatever comes to their mind. I take feedback very seriously and if you have a good idea I won't hesitate to implement it. Development of Charlotte's Utilities is made possible by Full Effect Hosting
