Amazon CEO says ‘beautiful’ new Alexa hardware is coming this fall
Amazon is gearing up to launch new hardware to go along with its AI-upgraded Alexa. During an interview with Bloomberg, Amazon CEO Andy Jassy said the company has a “brand new lineup of devices that are coming in the fall that are beautiful.” On Wednesday, Amazon revealed Alexa Plus, a more conversational version of the […]
[讨论]回归萌新问一下四枪阵容该怎么玩源
四枪阵容指c麦克雷艾什索杰恩，n雾子和尚伊拉瑞安娜，国服这些英雄相当常见，t往往还是个毛妹西格玛鲑鱼大帝这种有办法克制源格挡的。
打这种阵容中距离拉侧面抢控制权的时候很容易拉出去二段跳的时候刚镖两下被枪位爆个头奶补一下瞬间去世，奶都来不及救，导致没格挡根本不敢用镖蹭能量，拉出去镖一下直接开格挡又没人打，单切后排的时候又几乎硬需求有格挡不然根本没有和几个枪位的博弈手段，打的很迷茫。

Apple will let parents share their kids’ ages to limit app access
Apple announced in a whitepaper that it plans to introduce a bunch of new child safety features, including letting parents share their kids’ age ranges with apps, refreshing the App Store’s age ratings system, and making it easier for parents to set up Child Accounts for their kids. The company says it will introduce the […]
The best iPhones
The wait is over — kind of. Apple’s iPhone 16 series is out, including the kinda affordable 16E, and its much-hyped Apple Intelligence has arrived courtesy of iOS 18.1. But if you’re expecting an entirely new kind of iPhone experience, well, I have some bad news for you. The AI features in iOS 18.1, including the writing […]
[杂谈]感觉这游戏神话人物皮也就那样，枪皮才是真谛
游玩中玩家自己实实在在能看得到武器模型，还有特殊音效、独家定制的击杀效果和检视动作，相比之下人物皮要效果没效果，要模型玩起来自己也看不到，配套的动作更是没有。更何况暴雪出英雄皮的频率远大于出枪皮的频率，好看的人物皮不输神话人物皮，但是你一把游戏只能用一套皮肤[s:ac:哭笑]强烈建议大家先换枪皮
估计三星还需要10个月才能启动其2纳米GAA工艺的量产
一份新的报告称，分析师们对三星在提高其尖端芯片良品率方面所取得的进步表示赞赏，并指出与三星在 3 纳米 GAA 技术上所遇到的障碍相比，三星的进步要好得多。 遗憾的是，三星仍有很大的改进空间，而且时间并不充裕。
在三星信心十足地向潜在客户展示这一技术并夺回失去的市场份额之前，还有许多工作要做，但时间并不站在该公司一边。 据《朝鲜日报》报道，爆料人@Jukanlosreve发现的细节显示，三星估计还需要 10 个月的时间才能启动 2 纳米 GAA 晶圆的实际生产。 不过，分析师认为三星这次的进展明显更好，这意味着它仍有机会在日程表范围内生产出健康的产量，以引起潜在客户的兴趣。
去年第四季度，晶圆代工部门已开始安装设备，以便在华城工厂的"S3"链上建立一条 2 纳米 GAA 生产线。 目前的计划是将现有的 3 纳米 GAA 生产线（基于 12 英寸晶圆，每月可生产约 15000 片）改造为 2 纳米生产线。 对于客户来说，试生产最早可能在今年进行。
The best Android phones
The Android ecosystem is all about choice. While iPhone owners have a smaller pool of new devices to pick from when it’s time to upgrade, there’s a wider range of choices on Android. Some Android phones even fold in half! Imagine. On the flip side, all that choice can make for some hard decisions. Here’s […]
Intel Posts Linux Kernel Patches For Supporting APX - Advanced Performance Extensions
Intel initially detailed Advanced Performance Extensions (APX) back in mid-2023 as extensions to double the number of general purpose registers and add other performance features. In the time since they have done a lot preparing the GCC and LLVM/Clang compilers for the new APX ISA features while finally today they sent out an initial set of patches for preparing the Linux kernel for APX processors.
Intel doesn't intend for Advanced Performance Extensions to be used in kernel-mode but rather just user-space applications. However, the Linux kernel needs to make accommodations around Advanced Performance Extensions for the new register state managed by the XSAVE instruction set, adjusting the XSAVE buffer offset, and ensuring all kernel assumptions are safe/relevant in an APX world.
A set of patches from Intel engineers today establish a "request for comments" baseline on Linux kernel support for Advanced Performance Extensions. The patches make kernel adjustments to the XSTATE code, go ahead in enabling APX support, and dropping MPX support as it collides with APX. Finishing up the Linux kernel removal of the Intel Memory Protection Extensions (MPX) support is needed since the new XSTATE component for APX is used in the position previously used by MPX - thus a fundamental conflict between MPX and APX although no processor exists that would support both features.
This RFC patch series is what lays out that initial APX enablement by the Linux kernel. As it's in an RFC state, it may still take some time before the design elements are all settled down and ultimately upstreamed.
I don't believe I've seen Intel publicly indicate what generation of processors will first feature APX. However, given that we are only seeing these kernel-side APX patches now and it will be some months before the patches are all worked through and upstreamed, and potentially a couple extra months before it's in turn with a stable kernel and beginning to appear in prominent Linux distributions, this is still a significant affair. As we already know for example that Diamond Rapids will have AVX10.2/512 support and compiler patches have made known ISA capabilities already for both Diamond Rapids and Clearwater Forest, given all things considered we're likely not going to see APX support until after that "Xeon 7" generation. So perhaps for "Xeon 8" is where APX will make its debut.
From these APX enablement patches for the Linux kernel further pointing to APX not coming with Granite Rapids or Clearwater Forest is that it notes testing was done just on an "internal Intel emulator." With Intel confirming in the recent Xeon 6500P and 6700P announcement that Clearwater Forest is already operational and fully functional, plus the fact of seeing Intel engineers bringing up Granite Rapids and Clearwater Forest hardware testing in other patches, the fact they are still relying on a simulator/emulator for APX testing punts its debut out past that point.
