budgie-desktop >= 10.7.2-6 update requires manual intervention

When upgrading from budgie-desktop 10.7.2-5 to 10.7.2-6, the package mutter43 must be replaced with magpie-wm, which currently depends on mutter. As mutter43 conflicts with mutter, manual intervention is required to complete the upgrade.

First remove mutter43, then immediately perform the upgrade. Do not relog or reboot between these steps.

Sandy Bridge: Setting Intel’s Modern Foundation

Processor companies typically iterate off proven designs, and for good reason. Changing too many things at once introduces a lot of risk. A lot of changing parts makes it hard to get a good picture of overall performance, so it also makes tuning difficult.…

IBM 大型机为何能生存到今天

2023-07-31 14:10 by 为了我们的家园

大型机堪称计算机中的恐龙，但它并没有像恐龙那样灭绝，至今仍然至关重要。它是霸王龙，其它桌面电脑和服务器都是被践踏的小哺乳动物。今天投入使用的大型机有约 1 万台，基本都是全球超大型企业在使用，其中包括三分之二的财富 500 强企业，全球 50 大银行中的 45 家，前 10 大保险公司中的 8 家，前 10 大零售商中的 7 家，前 10 大电信公司中的 8 家。绝大部分大型机都由 IBM 制造。大型机源自第一代计算机技术，但并没有精简成低成本的桌面电脑或服务器，而是演变成去处理海量数据工作负载，例如大批量数据处理和高容量金融交易。在早期 IBM 有很多竞争对手，如 Univac、Rand、Sperry、Amdahl、GE、RCA、NEC、Fujitsu、Hitachi、Unisys、Honeywell、Burroughs 和 CDC 等，它们占据了二成市场份额，IBM 占八成。今天 IBM 是唯一的大型机制造商，它的竞争对手变成了云服务商，但使用大型机的企业发现，迁移到云端未必划算，云服务的可靠性也没有大型机高。大型机拥有惊人的冗余能力和高达 99.999% 的可靠性，它们的主要组件如 CPU、内存和硬盘都支持热插拔，无需关机就能替换。
