@OptiChads @thejonmccoy cos when you multiply by a tan you're committing a sin

@OptiChads @thejonmccoy 因为当您乘以棕褐色时,您就犯了罪

@thejonmccoy Please don't use tan to generate your wallet seeds.

@thejonmccoy 请不要使用棕褐色来生成您的钱包种子。

The spikes emerge from good approximations to the circle ratio:
11/7 ~= tau/4 (or pi/2)
11 ~= 7/4 * tau (one full rotation plus 270.25')
So tan(11) is high: -225.95
The spikes near 355 and 710 are "echoes" of 11/7 created because 355/113 is an *amazing* approximation of tau/2

尖峰来自与圆比的良好近似:
11/7 ~= tau/4(或 pi/2)
11 ~= 7/4 * tau(一整圈加上 270.25')
所以 tan(11) 很高:-225.95
355 和 710 附近的尖峰是 11/7 的“回声”,因为 355/113 是 tau/2 的*惊人*近似值

What's even more interesting is that tan(int) is *not* a random number generator. There's fascinating patterns in the data.
One way to look at it is: if tan(x) is very high, x is very close to a 90' or 270' angle. So if tan(x) and tan(y) are high, tan(x + 2y) is also high. https://t.co/W2QlBsUDBM

更有趣的是 tan(int) *不是*随机数生成器。数据中有迷人的模式。
一种看待它的方法是:如果 tan(x) 非常高,则 x 非常接近 90' 或 270' 角。因此,如果 tan(x) 和 tan(y) 很高,则 tan(x 2y) 也很高。 https://t.co/W2QlBsUDBM

And if you use tan^2 you get into total crazy land. https://t.co/g1Z9gIlRGL

如果您使用 tan^2,您将进入完全疯狂的土地。 https://t.co/g1Z9gIlRGL

I continue to find probability distributions with infinite means fascinating. Particularly how their averages *don't converge* as you sample more values.
You can even replicate the behavior deterministically with "tan at integers" as a pseudo-RNG. https://t.co/KmfUXpqKLx

我继续发现具有无限均值的概率分布令人着迷。特别是当您采样更多值时,它们的平均值如何*不收敛*。
您甚至可以使用“整数 tan”作为伪 RNG 来确定地复制行为。 https://t.co/KmfUXpqKLx

@AutismCapital My .png this morning was not good enough? ☺️
(Or does it need to be .jpg to be truly valuable in this space?)

@AutismCapital 我今天早上的 .png 还不够好? ☺️
(或者是否需要 .jpg 才能在这个领域真正有价值?)

@anderssandberg @MichaelDPlant Do we know of any ways to continue doing computation indefinitely given what we know about the universe / physics today? Or are we still at "there's only a limited number of non-reversible bit ops until we get to max entropy and we're screwed"?

@anderssandberg @MichaelDPlant 鉴于我们今天对宇宙/物理学的了解,我们是否知道任何方法可以无限期地继续进行计算?还是我们仍然处于“只有有限数量的不可逆位操作,直到我们达到最大熵并且我们被搞砸了”?

@soulbound_human That's just ABI encoding, which pads everything to 32 bytes.

@soulbound_human 那只是 ABI 编码,它将所有内容填充到 32 个字节。

@carlg_dev Also, the long lead time on blockchain upgrades basically means that we have to start building an upgrade now to have a shot at getting it out before the scaling problem becomes critical.

@carlg_dev 此外,区块链升级的漫长准备时间基本上意味着我们现在必须开始构建升级,以便在扩展问题变得严重之前有机会将其解决。

@carlg_dev The issue is that we already know from calculations that just doing one is not enough. During the high fee era last year even a fully optimized zkrollup tx cost $0.25.

@carlg_dev 问题是我们已经从计算中知道仅仅做一个是不够的。在去年的高收费时代,即使是完全优化的 zkrollup tx 也要 0.25 美元。

@carlg_dev Why compared to? Stack on top.

@carlg_dev 为什么相比?叠在上面。

@NathanpmYoung @GiveWell Good rebuttal but too polite and technocratic imo. The WSJ piece was so bad, the tone it *deserved* to get in response is closer to @slatestarcodex reviewing Neom.

(Maybe this is what @Aella_Girl meant by that critique of EA she made recently?) https://t.co/OFbe76mL1l

@NathanpmYoung @GiveWell 很好的反驳,但太有礼貌和技术官僚了。 《华尔街日报》的文章太糟糕了,它*应得的*回应的语气更接近@slatestarcodex 审查 Neom。

@ISHIBELIEVE The ideas mentioned in the tweet above will decrease gas fees on rollups by up to 7x.

@ISHIBELIEVE 上述推文中提到的想法将使汇总的汽油费减少多达 7 倍。

Some quick theorycrafting of how much data space we can save by improving compression (especially in rollups).
ERC4337 signature aggregation ( https://github.com/eth-infinit... ) is essential to this. https://t.co/nrlcOpVJKb

通过改进压缩(特别是在汇总中)我们可以节省多少数据空间的一些快速理论。
ERC4337 签名聚合(https://github.com/eth-infinit...< /a> ) 对此至关重要。 https://t.co/nrlcOpVJKb

@larry0x There was one that was a multisig where the attacker hacked enough keys to take it over. I'd count that one as "would not have happened if it was a rollup".

@larry0x 有一个是多重签名,攻击者破解了足够多的密钥来接管它。我认为那是“如果是汇总就不会发生”。

@DiligentNinja6 It's ok, I read your tweet. Thank you for your perspective. I will try to scam less in the future.

@DiligentNinja6 没关系,我读了你的推文。谢谢你的观点。以后我会尽量少骗人。

@Ukraine_DAO Capitalize the other letter in the second word instead, it makes the acronym better. 😊

@Ukraine_DAO 将第二个单词中的另一个字母大写,它使首字母缩略词更好。 😊
