So no Medicare for all candidates can say one simple thing clear - employer-based insurance is annoying for everyone, and single payer gives government more power to negotiate. Is that really so hard to say or so risky to say?

有的时候呢想想很多事情真的不知道是为什么。比如说我上学的时候一直对读万卷书行万里路的后半句不是很感兴趣,导致今天很多时候国家名字和地图还对不上号。以我上学的时候碰到的出色地理老师的数量来说,真的还挺不好意思的。

My view on Greta Thunberg builds on one thing: are we doing enough about climate change? If not so, what exactly is the harm about climate gaining some attention via protests and symbolic movements?
2/2

Many attacks about Greta Thunberg point to her "bringing no real solution". In fact, Sweden and nearby airlines recorded a reduction in travelers partially because of climate protests. Educating people about the climate IS part of the solution.t.co/9WQqmEK1xe?amp=1
The problem of climate is more than "We need a solution." Some solutions, like hybrid cars, existed for a long time. It's also about people and the government's unwillingness to act. 1/2

北大说被退档考生成绩太差跟不上,退档是为了考生好,让我想起来这么一件事。

美国南北战争的时候南方的指挥官罗伯特•李认为奴隶制是一种“道德上和政治上的邪恶”。但是他为什么要跟废奴主义者作战呢?因为他觉得“黑人在这里得到的痛苦的训练对他们种族的成长是有利的”,所以白人在帮黑人的忙,而让黑人自由是对他们不好的。

你看,不管什么时候,不管什么样的歧视,都能以“我是为了弱势群体好,不然他们自己跟不上”的理由,堂而皇之的出现。罗伯特李想不起来问一问黑奴愿不愿意被奴役,北大招生办也想不起来问一问考生自己到底愿意做什么选择。

其实冠冕堂皇的理由下面到底是什么动机,谁都明白。

04年之前,虽然非法移民是犯罪,但这条法律从来没被执行过。

在场10个总统候选人没有一个能想起来这个吗…

b) Obama administration forfeited public option to get support for the ACA, it got attacked, became a political liability and caused Dems two elections, and got repealed anyway.

c) Clinton had a relatively moderate platform. It's not like she won the presidency. d) And look like what happened to the moderates on the right like Kasich. So tell me, why should someone on the left trust this time would be different?

So, I've been reading a lot of commentaries saying "Y'all Dems better not pursue Medicare for all or you'll lose the moderate votes". Look, Not that I am particularly fond of medicare for all, but the logic from the supporters is not that hard to understand:
a) There are countries that have universal healthcare and it seems working. 1/

几段历史:

* 罗斯福上台至尼克松赢得第一任选举期间(32-68),民主党赢得了9场总统选举中的七场。
* 这期间南部各州是民主党的铁票仓。
* 然而这并不是一个“白左”的时代。这个时期两党都有社会政策意义上的保守翼和自由翼。国会基本上由保守翼控制:南部各州农村支持种族隔离的民主党人和北方的共和党人组成的联盟从38年到64年控制着国会。
* 这个时期的共和党是少数族裔权益和黑人平权运动的支持者,而民主党参议员们反而坚决反对1964年的平权法案。
* 大逆转发生在1968年,这一年尼克松赢得了南方几个民主党铁票仓的选票,从此以后南部各州慢慢成为共和党的铁票仓。而共和党也开始慢慢丢掉少数族裔的选票。
* 尼克松的主要政纲包括 - 坚持州权必须要得到保障,反对福利国家,抑制边境犯罪,反对强行整合黑白学区。听起来很耳熟?那就对了。

纽约时报独立日刊发了一篇很有趣的报道:美国的社会流动性最差的南方(家庭贫穷的人获得顶级收入的概率最低)反而是对“靠个人努力可以让人摆脱贫困“最乐观的地区。一种解释是在这些地区的社会流动性如此糟糕,不这么想的话,人会没有活下去的动力。另外文中还提到一个很有意思的现象,美国人普遍高估社会流动性,而欧洲人则普遍低估。

So a Leetcode problem does not provide any input range and accept an overflowed integer as the correct answer, that means it's totally ok to have that bug in practice right?

The compressed CUDA package on Arch reached 2.1 GiB, probably half the size of all the rest installed packages on my EC2 instance putting together - Meanwhile, the gcc package is less than 50 MiB. The last time I see such a bloated dev package is bazel, btw.

Trying to do some Leetcode, a few complaints: 1. So many meaningless variant names? u,v,s,g... . 2. Quite a few poor interfaces, for an array of 2-d points, quite a few questions use vector<vector<int>>... 3. raw new/delete flying in the code.

I can kinda understand why ACM/ICPC is this style because the focus is speed... But for an interview prep site primarily targeting software engineers - Really?

Keep hearing, "New mac sucks, but I don't have other choices because Windows is just awful."

a) Windows is actually a working system with loads of software and quite a good development environment for almost everything.

b) Today's Linux offers everything Mac can provide in terms of a development environment, arguably better, esp. regarding package management and backend development.

Just did some remote development 34,000 feet above ground using visual studio code, some lag in ssh parts and file operations but tolerable. A really good remote development implementation.

Not that I like Huawei much, but the incident reflects on the problem of our reliance on closed frameworks and infrastructures - once the provider decides you are not following rules, or they don't benefit enough, your entire product is in jeopardy.

Moreover, ponder for a moment how many close-sourced services we rely on for developing *open source* software, GitHub, Travis CI,... It is not a rarity that some big companies just close projects or shutdown APIs randomly.

我不喜欢华为,特别是华为的市场部门。但是我觉得这件事情充分展现了依赖非开放架构的问题:一旦市场统治者决定你不符合游戏规则,或者是仅仅觉得他们在产品上收益不够,你的整个服务都可能瞬间崩塌。

而可怕的是,今天的开源产业链严重的依赖非开源的服务,Github, Travis CI, .... 哪天这些项目出了问题的话,整个开源世界都会受到影响。大公司随意砍产品或者关掉API的事情不是一起两起了。
