Curve fitting - this needs to be shared here :-)

Science is a differential equation. Religion is a boundary condition.
Alan Turing
Interesting quote but I would disagree somewhat. Science is *both* a differential equation and a boundary condition. Religion is trying add a new boundary condition which make the differential equation unsolvable.

Understanding a little bit more about the #fediverse through data. Here is a plot of all #fediverse instances at instances.social as a function of their number of users and toots (statuses) and if they are open for new accounts. In general, instances are small in the number of users (median = 28). Interestingly, there are a lot of small, very active, and closed servers in the #fediverse. Also, some of the biggest servers are Japanese communities.
Seriously though, fedi was *built* by furries, trans and queer folk, disabled neurodivergent people.
This is *the reason* the culture here is what it is. Why CWs are a thing. Why image descriptions are a thing. Why privacy matters here. Why moderation tools not only exist, but are usable — and used.
If you had joined and asked yourself "wow, how come this place is so chill and kinda… nice?" — that's thanks to all the nice people from communities some people call "weird".
So #KeepFediWeird.
顺便觉得经常看到很多人犯的一个逻辑错误就是把个体的经历当做某地普遍性的特性。比如有人从中国到美国,信誓旦旦跟我说美国不卖有护翼的卫生巾,每次回国要人带。但我跟她去了一趟Target就指出来明明有只是她自己没看到………… 但是她就很容易地把她自己个人的经历,找不到有护翼的卫生巾,推广到两个国家的特性。说这东西中国有美国没有。
前几个月看到一个姑娘来了加拿大参加会议几天一口咬定加拿大物价比瑞士高…………我很想说那是你会议酒店和附近的物价高。
然后好基友昨天跟我说一个人四肢瘫痪到厄瓜多尔找到一个妹子和他结婚。于是他发帖说厄瓜多尔人是世界上最有同情心的人。然后被厄瓜多尔人纷纷鄙视表示没有的事。
还有日本人住在北京说喜欢住中国因为没有复杂的人际关系。其实是因为他们逃脱了日本的人际关系,又不在中国建立关系而已。
还有美国人跑到魁北克,说魁北克很好因为魁北克不谈政治,没有美国那种两党对立 (我不看本地新闻不懂法语-=没有 系列)。
不过我觉得最大的问题其实还是很多刚出国的朋友很容易在享受一些优待后,把新地方想象成一个完美的地方。 觉得新地方是他们的promised land。这样有啥问题呢?问题就是他们对当地的问题视而不见,看到学生游行,少数族裔游行,觉得他们没事儿找事儿。因为他们的应许之地怎么会有问题呢?!这其实我觉得,就是很多华川的理论根基,他们无法承认他们千辛万苦移民跑出来的地方不是(大致上)完美的,因为那就是对他们人生轨迹的否认。既然是大致完美公平的,那现在这些人叽叽歪歪闹事抱怨,在他们眼里就是没事找事游手好闲了。所以我总觉得,移民的时候要记得,you are moving from a place that sucks a lot to a place that sucks less. 才能继承本地历史文化,包括他们的种种问题。 #乱写写
It's Friday and version 1.2 of "The many branches of the Fediverse" is published. Thanks everyone for your interest and engagement.
There is a changelog at the bottom of the post with more info, and you are welcome to download hi-res PNG and PDF versions of the diagram.
Do feel free to use this visual in any way you like, in your presentations, publish in your own spaces, etceteras. I'm just glad if you find it useful.
There is a meme, in the original sense of that word, going around that #Musk bought #Twitter to destroy it. Firing 3/4 of the employees, removing effectively all moderation, the $8 blue checkmark special ... it's all part of a cunning master plan. After that he'll put on an iron mask and buy a small Eastern European country.
Naaah.
First of all, if he really wanted Twitter to go away, he could do that, you know? Fire *all* the employees, travel around the world personally pulling the plugs on every server, auction off the physical assets, and go back to cars and spaceships and flamethrowers. Nothing's stopping him. There would be lawsuits, but he's looking at plenty of those already: a few more should be no big deal.
Second, if there's anything bigger than his stock portfolio, it's his ego. Twitter is his most visible public forum. It's where he shares his semi-coherent ramblings with the world for legions of followers to repost like the words of the one true prophet.
Third, it's a rather large investment, and while I'm reasonably sure he'll lose a lot of money on it, I don't believe he *wants* $44 billion to disappear. His fan base might start experiencing seeds of doubt, and we can't have that.
A much simpler explanation is that he's in over his head.
He doesn't understand what makes Twitter valuable to its current user base. He has no grasp of how small his cult is in comparison to the internet as whole. He thinks his imprimatur is so magical that everything he touches will be a hit. He believes every word of his utopian babble, no matter how incoherent. Worrying about contradictions is for the little people.
Destruction will come, sure as the snowfall. But it won't be the work of an evil genius. That's *my* job.
Tesla Autopilot
首先,Tesla 根本就不应该把一个处于”beta 状态”的功能,自动推送到所有 Model S 的系统里面。实际上,像 autopilot 这种功能,关系到人的生命安全,根本就不应该有”beta版本”或者“测试版本”之说。Tesla 把这样不成熟的系统,强制推送给用户,然后又说如果出了事故,用户负所有责任,这是一种推卸责任的做法。要知道,没有任何人愿意拿自己的生命给 Tesla 做“beta 测试”。
另外,就算是用户没有仔细阅读 autopilot 的使用说明,在“不该”用它的地方(比如路面线条不清晰的地方)使用了autopilot,如果出了车祸,Tesla也应该负完全的责任。理由如下:
- 作为用户,他们没有义务阅读并且深刻的理解 autopilot 的局限性。在软件行业,存在一种习惯性的“责备用户”的不良风气。如果软件的设计有问题,用户没记住它的毛病,没能有效地绕过,那么如果出了问题,一般被认为是用户的错。Tesla 想把软件行业的这种不正之风,引入到人命关天的汽车行业,那显然是行不通的。
- Tesla 的 autopilot 实现方式幼稚,局限性实在太多。天气不好的时候不行,路面上的边界线不清晰也不行,光线不好或者有阴影不行,路上有施工的路桩不行,高速出口不行,…… 实际上,在如此苛刻的限定条件下,任何一个汽车厂商都可以做出 Tesla 那种 autopilot。
我自己的便宜 Honda 车,就有偏离车道时发出警告的功能(Lane Drift Warning,LDW)。装个摄像头,来点最简单的图像处理就搞定。在Indiana大学的时候,我们有一门本科级别的课程,就是写代码控制一辆高尔夫球车(也是电动车呢),沿着路面上的线条自动行驶。这根本没什么难度,因为它能正确行驶的条件,实在是太苛刻了。
其它汽车厂商很清楚这种功能的局限性,所以他们没有大肆吹嘘这种“线检测”的技术,或者把它做成autopilot。他们只是把它作为辅助的,提示性的功能。这些汽车厂商理解,作为一个用户,他们不可能,也不应该记住autopilot能正确工作的种种前提条件。
- 用户没有足够的能力来“判断”autopilot正常工作的条件是否满足。比如,路上的线还在,但是被磨损了,颜色很浅,那么autopilot到底能不能用呢?谁也不知道。把判断这些条件是否满足的任务推给用户,就像是在要求用户帮Tesla的工程师debug代码。这显然是不可行的。如果autopilot能够在检测到道路条件不满足的情况下,自动警告用户,并且退出自动驾驶模式,那还稍微合理一些。
- 用户也许没有足够的时间来响应条件的改变。Autopilot自动驾驶的时候,车子有可能最初行驶在较好的条件下(天气好,路面线条清晰),然而随着高速行驶,路面条件有可能急速的变化。有可能上一秒还好好的,下一秒路面线条就不再清晰(视频5貌似这种情况)。路面条件的变化突如其来,驾驶员没有料到。等他们反应过来,想关闭autopilot的时候,车祸已经发生了。这种情况如果上诉到法庭,稍微明理一点的法官,都应该判Tesla败诉。
- Autopilot显摆出的“高科技”形象,容易使人产生盲目的信任,以至于疏忽而出现车祸。既然叫做“autopilot”,这意味着它能够不需要人干预,自动驾驶一段时间。既然用户觉得它能自动驾驶,那么他们完全有理由在到达高速路口之前(比如GPS显示还有一个小时才到出口),做一些自己的事情:比如看看手机啊,看看书啊,甚至刷刷牙…… 不然,谁让你叫它是“autopilot”的呢?我坐飞机时,就见过飞行员打开autopilot,上厕所去了。如果启用了autopilot还得一秒钟不停地集中注意力,那恐怕比自己开车还累。自己开车只需要看路,现在有了autopilot,不但要看路,还要盯着方向盘,防止autopilot犯傻出错……
- Tesla把“beta版”的autopilot推送给所有的Model S,是对社会安全不负责任的做法。你要明白Murphy’s Law:如果一个东西可能出问题,那么就一定会有人让它出问题。Autopilot的功能不成熟,限制条件很多,不容易被正确使用,这不但对Model S的车主自己,而且对其他人也是一种威胁。汽车不是玩具,随便做个新功能,beta版,让人来试用,是会玩出人命的。我觉得Tesla的autopilot,跟无照驾驶的人一样,应该被法律禁止。由于autopilot的复杂性和潜在的危险性,使用autopilot的用户,应该经过DMV考核,在驾照上注明“能正确使用Tesla autopilot”,才准上路。
- 关系到人的生命安全的“免责声明”和“用户协议”,在法律上是无效的。在美国,到处都存在“免责声明”之说。比如你去参加学校组织的春游活动,都要叫你签一个“waiver”,说如果出了安全事故或者意外,你不能把学校告上法庭。这种免责声明,一般在法律上都是无效的。如果由于学校的过错而致使你的身体受了损伤,就算你签了这种waiver,照样可以把学校告上法庭。我估计Tesla的autopilot在启动时,也有这样的免责声明,说如果使用autopolit而出现车祸,Tesla不负责任。由于autopilot直接操控了你的车子,如果真的出了车祸,这跟其它的waiver一样,都是无效的。你照样可以上法庭告他们。
由于意识到这个问题,知道出了问题自己是逃不掉责任的,Tesla最近又通过强制的软件更新,对autopilot的功能进行了一些限制,说是为了防止用户“滥用”autopilot做一些“疯狂”的事情。Tesla很疯狂,反倒指责用户“滥用”和“疯狂”。这让人很愤慨。
对autopilot进行限制的同时,Tesla又推出了beta版的“自动趴车”和“召唤”(summon)功能。这些功能貌似很酷,然而它们也附带了许多的限制条件。你只能在某些地方,满足某种特定条件,才能用这些功能。如果你违反这些条件,出了事故,Tesla声称不负责。
这些能够让车子自己移动的功能,跟autopilot一样,同样会给社会带来安全隐患。比如,有人在不该使用自动趴车和summon功能的地方用了它,就可能会导致车祸。这不是用户的问题,而是Tesla根本不应该发布这些不成熟的技术来哗众取巧。
