    1. Don't you notice that the power of seeing and what's seen dohave such a need?"

      I find this certain sentence within this section of the reading to be actually a bit confusing to myself. The question that is being posed here is just something I don't quite understand. When the question of "don't you notice that the power of seeing and what's seen do have such a need?" is being asked, what exactly is the difference between the power of seeing and what's seen? I understand it is a very philosophical question I suppose, but what does the question and the difference between the two mean?

    1. The obvious event is the so-called ‘bonne saison’, a French zooarchaeological term for the time at the end of winter when rivers unfreeze, the snow melts, and the landscape begins to green. This of course varies by several weeks from the south to the north of Europe, but corresponds approximately to late spring. We hypothesize that spring, therefore, with its obvious signals of the end of winter and corresponding faunal migrations to breeding grounds, would have provided an obvious, if regionally differing, point of origin for the lunar calendar.

    1. 经认证,在spring boot的版本号为1.5.0的时候 添加spring-boot-starter-reids就找不到jar包了,也就是这个jar包直接被废弃了。所以千万要注意的是:如果你的spring boot的版本号在1.5.0以后的,添加redis的jar包就必须是spring-boot-starter-data-redis。。。。

    1. 新增了一个refresh范围的scope,同样用了一种独特的方式改变了Bean的管理方式,使得其可以通过外部化配置(.properties)的刷新,在应用不需要重启的情况下热加载新的外部化配置的值。
    1. @Autowired

      需要lazy注解

    2. Disposable 方法的注册

      用于缓存spring的解构者

    3. doCreateBean 管理了 Bean 的整个生命周期中几乎所有的关键节点
    4. 寻找不到对应的 Bean,一定会如案例 2 那样直接报错

      集合、数组不会

    5. CglibSubclassingInstantiationStrategy.LookupOverrideMethodInterceptor
    6. 根据参数来寻找对应的 Bean

      寻找的优化: 1. 事先扫描构建bean的索引(并不实际构建bean) 1. 当需要找个bean的时候,再去构建bean

    1. 这个需要利用Spring事务的一个特性TransactionSynchronization,注册一个同步钩子,自动把相关代码放到事务完成之后执行,我们使用拦截器拦截rabbitTemplate.convertAndSend方法,实现不用修改现有代码自动把发送MQ消息逻辑移到事务之外

      spring事务拦截机制

    1. @EnableBinding:将定义通道的接口绑定到某个 Bean 以便于我们可以通过该 Bean 操作通道进行发送和接收消息。

      注解的参数是class,class实例化成一个bean,通过bean来操作消息

    2. 统一编程模型
    3. SpringCloud Stream 出生这么久还不广泛流行的原因之一就是,这一套技术体系涉及的东西太多了,万一生产环境出现什么疑难杂症,需要去阅读源码解决的话,这样的技术工作量是很超出预期的。

      缺点

    4. 不得不说集成 SpringCloud Function 之后,消息的发送和接收又迈进了一个崭新的阶段,但 <functionName> + -in- + <index> 这样的配置规约我觉得让我有些难受......甚至目前我认为 3.1 之前被废弃的注解方式也许更适合我们开发使用

      新趋势

    1. 我们看到两个消费者都收到了消息

      每个消费者实例都产生一个匿名的queue

    2. 创建一个消费者组

      实际上是将两个消费者实例绑定同一个queue

    3. 我们需要监听之前创建的通道greetingChannel。让我们为它创建一个绑定

      如果消费者和生产者在同一个实例中,会优先走本地调用,不会产生队列消息。消费者能正常接收mq消息

    1. It really only takes one head scratching issue to suck up all the time it saves you over a year, and in my experience these head scratchers happen much more often than once a year. So in that sense it's not worth it, and the first time I run into an issue with it, I disable it completely.
    1. When we see the world from the vantage point of all-at-oneness, always right here, we can be said to be like a pearl in a bowl. Flowing with every turn without any obstructions or stoppages coming from our emotional reactions to different situations. This is a very commonly used image in Zen — moving like a pearl in a bowl. As usual, our ancestors comment on this phrase, wanting to break open our solidifying minds even more. Working from Dogen’s fascicle Shunju, Spring and Autumn, we have an example of opening up even the Zen appropriate phrase — a pearl in a bowl. Editor of the Blue Cliff Record Engo ( Yuan Wu) wrote: A bowl rolls around a pearl, and the pearl rolls around the bowl. The absolute in the relative and the relative in the absolute.   Dogen: The present expression “a bowl rolls around a pearl” is unprecedented and inimitable, it has rarely been heard in eternity. Hitherto, people have spoken only as if the pearl rolling in the bowl were ceaseless.

      This is like the observation I often make in Deep Humanity and which is a pith BEing Journey

      When we move is it I who goes from HERE to THERE? Or am I stationary, like the eye of the hurricane spinning the wild world of appearances to me and surrounding me?

      I am like the gerbil running on a cage spinning appearances towards me but never moving an inch I move while I am still The bowl revolves around this pearl.

    2. The absolute in the relative and the relative in the absolute

    1. This also made me think of church bulletin ads, which all look the exact same way, except maybe it’s just a Catholic thing2?

      I thought of the same aesthetic as well, in part because it wasn't as "busy" as the comic book page aesthetic.

      I've been thinking about this sort of thing off and on myself.

      I too almost immediately thought of Fraidyc.at and its nudge at shifting the importance of content based on time and recency. I'd love to have a social reader with additional affordances for both this time shifting and Ton's idea of reading based on social distance.

      I'm struck by the seemingly related idea of @peterhagen's LindyLearn platform and annotations: https://annotations.lindylearn.io/new/ which focuses on taking some of the longer term interesting ideas as the basis for browsing and chewing on. Though even here, one needs some of the odd, the cutting edge, and the avant garde in their balanced internet diet. Would Spring '83 provide some of this?

      I'm also struck by some similarities this has with the idea of Derek Siver's /now page movement. I see some updating regularly while others have let it slip by the wayside. Still the "board" of users exists, though one must click through a sea of mostly smiling and welcoming faces to get to it the individual pieces of content. (The smiling faces are more inviting and personal than the cacophony of yelling and chaos I see in models for Spring '83.) This reminds me of Stanley Meyers' frequent assertion that he attempted to design a certain "sense of quiet" into the early television show Dragnet to balance the seeming loudness of the everyday as well as the noise of other contemporaneous television programming.

      The form reminds me a bit of the signature pages of one's high school year book. But here, instead of the goal being timeless scribbles, one has the opportunity to change the message over time. Does the potential commercialization of the form (you know it will happen in a VC world crazed with surveillance capitalism) follow the same trajectory of the old college paper facebook? Next up, Yearbook.com!

      Beyond the thing as a standard, I wondered what the actual form of Spring '83 adds to a broader conversation? What does it add to the diversity of voices that we don't already see in other spaces. How might it be abused? Would people come back to it regularly? What might be its emergent properties?

      It definitely seems quirky and fun in and old school web sort of way, but it also stresses me out looking at the zany busyness of some of the examples of magazine stands. The general form reminds me of the bargain bins at book stores which have the promise of finding valuable hidden gems and at an excellent price, but often the ideas and quality of what I find usually isn't worth the discounted price and the return on investment is rarely worth the effort. How might this get beyond these forms?

      It also brings up the idea of what other online forms we may have had with this same sort of raw experimentation? How might the internet have looked if there had been a bigger rise of the wiki before that of the blog? What would the world be like if Webmention had existed before social media rose to prominence? Did we somehow miss some interesting digital animals because the web rose so quickly to prominence without more early experimentation before its "Cambrian explosion"?

      I've been thinking about distilled note taking forms recently and what a network of atomic ideas on index cards look like and what emerges from them. What if the standard were digital index cards that linked and cross linked to each other, particularly in a world without adherence to time based orders and streams? What does a new story look like if I can pull out a card either at random or based on a single topic and only see it or perhaps some short linked chain of ideas (mine or others) which come along with it? Does the choice of a random "Markov monkey" change my thinking or perspective? What comes out of this jar of Pandora? Is it just a new form of cadavre exquis?

      This standard has been out for a bit and presumably folks are experimenting with it. What do the early results look like? How are they using it? Do they like it? Does it need more scale? What do small changes make to the overall form?

    1. Prof Peter Hotez MD PhD. (2022, February 8). So it’s Groundhog Day for Covid, no BA.2 and we get an early Covid spring; if BA.2 accelerates we get 6 more weeks of Covid winter [Tweet]. @PeterHotez. https://twitter.com/PeterHotez/status/1491144988738322433
