Valve Says Steam Machine ‘Shipping This Summer’
Valve says its long-awaited Steam Machine and Steam Frame are both “shipping this summer.” The company is also expanding its Verified program beyond Steam Deck to cover the new hardware. “Steam Verified is a developer-focused program where game makers ensure that their titles are capable of running on the Deck (meaning they’ll run fine under Linux), that the UI elements and tex … ⌘ Read more

为什么燃油车很少刹车失灵，而新能源汽车刹车失灵概率高，这是什么原因？
我觉得横向对比吧，把相同的因素尽可能剔除掉，仅保留明显差异的变量。

因此关于驾驶辅助啊，自动驾驶这些我们先不考虑它。

我觉得其实最主要的因素可以归结到两点：

1. 同级别的电动车，在重量上显著高于燃油i车（又在动力上很容易达到高速）
   
2. 电动车为了操作便利性引入的“单踏板模式”对于用户的习惯培养
   

我们先说第一点： 重量！

将车辆制动下来，在燃油车时代和电动车时代有点小区别：

• 燃油车的制动力，通常包括：发动机制动（来自于泵气损失）+制动系统制动力
  
• 电动车的制动力，来自于：能量回收力矩+制动系统制动力
  

而需要制动的动能呢，本身和什么形式无关。只与车辆的速度和质量有关。根据高中物理中包含的动能公式，制动总能量为

Lab6, the zine about itself, just released Issue 3! It’s a PDF/Gemini/HTML/TeX/x86 polyglot this time. Great stuff! https://lab6.com/3

TeX is Long Software. LaTeX is not.

automatically generated #TeX equations implemented in !sndkit

being able to render TeX math equations to PNG files is pretty empowering, because it allows me to write about more technical things here that would otherwise be more difficult to communicate in plaintext.

figured out how to render a single TeX equation to a PNG file today: !render_one_equation

In God we trust
It is interesting to find out, at times when some minority wants to have removed “…under God…” from the Pledge of Allegiance, about this —it refers to the Great Seal of the United States of America motto:

The federal courts have held that the motto symbolizes the historical role of religion in our society, Lynch, 465 U.S. at 676, formalizes our medium of exchange, see O’Hair v. Blumenthal, 462 F. Supp. 19, 20 (W.D. Tex.), aff’d sub nom. O’Hair v. Murray, 588 F.2d 1144 (5th Cir. … ⌘ Read more
