吴俊伟：我觉得可以分两类人，一种是为了找工作而刷题的，一种是单纯为了学习算法。对于前一种可以多找些高频面试题，后一种就按照现在来就好了。提高参与度的话就让大家可以把自己觉得好的题目或者做不出来的题目，又或者是面试遇到的题目发出来让大家看看，一起讨论。 23 | 吴俊伟：还有平台可以不用局限leetcode，洛谷，计蒜客，牛客网，poj都行的 24 | 小林：可以发布一些算法比赛消息 25 |

2018-09-08T00:00:00+08:00 4 | --- 5 | sync.Once可以实现单例模式，确保sync.Once.Do(f func())只会被执行一次，可以初始化某个实例单例。 6 | 7 | 针对Golang 1.9的sync.Once，与Golang 1.10一样。 源代码位置：sync\once.go。 8 | 9 | ## 结构体 10 | Once结构体定义如下： 11 | ```go 12 | type Once struct { 13 | m Mutex 14 | done uint32 // 初始值为0表示还未执行过，1表示已经执行过 15 | } 16 | ``` 17 | 18 | ## Do 19 | ```go 20 | func (o *Once) Do(f func()) { 21 | // done==1表示已经执行过了，直接结束返回 22 | if atomic.LoadUint32(&o.done) == 1 { 23 | return 24 | } 25 | // 锁住对象，避免并发问题 26 | o.m.Lock() 27 | defer o.m.Unlock() 28 | if o.done == 0 { 29 | // 执行f函数后将done设置为1 30 | defer atomic.StoreUint32(&o.done, 1) 31 | f() 32 | } 33 | } 34 | ``` 35 | 36 | 需要注意的是执行f函数是同步进行的，也就是说可能存在阻塞问题。 37 | 38 | --------------------------------------------------------------------------------

If the Pool holds the only reference when this happens, the item might be deallocated. 28 | 29 | ## 参考 30 | 31 | 1.

 36 | - id的生成规则是什么
 37 | - 如果索引里面不保存handle_id，那怎么根据索引找到这行数据呢
 38 | - 索引字段很大会不会有问题，作为id的一部分的话 39 | - 单条6m的限制是怎么计算出来的？还是压力测出来的？ 40 | - ddl时，job放到tikv的队列，tikv是分布式的，job具体是放到哪个tikv上的呢？ 41 | - 并行ddl 如何跑 42 | - tikv整体上可以看成一个kv store 43 | - region这部分概念可以配合hbase去看看能更好的理解 44 | - 难道own tidb server要遍历所有的tikv server上的queue，去取ddl的job？ 45 | - tidb 的统计信息也是放一个表里面，每次parse 都会去拿这个信息，这样的话请求到一个region,这个表是不是很容易成为热点 46 | 47 | ## 观看视频 48 | 49 | {{< youtube id="Rcrm4w7sqbM" >}} 50 | -------------------------------------------------------------------------------- /content/night/51-2019-07-18-sync-errgroup.md: -------------------------------------------------------------------------------- 1 | --- 2 | desc: Go 夜读之 sync/errgroup 源码阅读 3 | title: 第 51 期 Go 夜读之 sync/errgroup 源码阅读 4 | date: 2019-07-18T21:10:00+08:00 5 | author: mai 6 | --- 7 | 8 | ## golang.org/x/sync/errgroup 9 | 10 | errgroup 唯一的坑是for循环里千万别忘了 i, x := i, x，以前用 waitgroup 的时候都是 go func 手动给闭包传参解决这个问题的，errgroup 的.Go没法这么干，犯了好几次错才改过来" 11 | 12 | ## 观看视频 13 | 14 | {{< youtube id="CQOZtzmgLvw" >}} 15 | -------------------------------------------------------------------------------- /content/night/52-2019-07-25-httprouter-guide.md: -------------------------------------------------------------------------------- 1 | --- 2 | desc: Go 夜读之 httprouter 简介 3 | title: 第 52 期 Go 夜读之 httprouter 简介 4 | date: 2019-07-25T21:10:00+08:00 5 | author: 曹大 6 | --- 7 | 8 | ## httprouter 简介 9 | 10 | 详细内容，可以查看 https://cch123.github.io/httprouter/ 11 | 12 | ## 观看视频 13 | 14 | {{< youtube id="BLYX6SKxFJA" >}} 15 | -------------------------------------------------------------------------------- /content/night/53-2019-08-01-build-in-delete-from-map-in-go.md: -------------------------------------------------------------------------------- 1 | --- 2 | desc: Go 夜读之 build in func delete from map 3 | title: 第 53 期 Go 夜读之 build in func delete from map 4 | date: 2019-08-01T21:10:00+08:00 5 | author: mai 6 | --- 7 | 8 | ## Go 夜读第 53 期 delete from map in go 9 | 10 | 突然有一个需求要删除 map 中的一些过滤数据。 11 | >由此查阅了一些资料，然后促成此次分享。 12 | 13 | PPT： 14 | [build-in func delete from map in go.pptx](https://github.com/talkgo/night/files/3453966/build-in.func.delete.from.map.in.go.pptx) 15 | 16 | ## 分享时间 17 | 18 | 2019-08-01 21:00:00 19 | 20 | ## 分享平台 21 | 22 | [zoom 在线直播 -

关于这个问题，可以参考这篇文章 [Production-ready Database Connection Pooling in Go](https://making.pusher.com/production-ready-connection-pooling-in-go/). 文章的建议是 MaxOpenConns 应该和实际的打开的连接数的监测值相关。然后按照 MaxOpenConns 的一定比值设置 MaxIdleConns，比方说 50%，这个值取决于你对业务的预估。每维持一个闲散连接，会造成 1MB 左右的客户端内存开销和 2MB 左右的数据库内存开销，CPU 开销相对小一点。文章还给出了一些 benchmark 的测试，在默认 MaxIdleConns 和 MaxIdleConns = 50% * MaxOpenConns 情况下的一个性能的对比，可以参考一下。 35 | 36 | ## 参考资料 37 | 38 | -

The list shows the pages' title and a summary of their content. 13 | 14 | [Show me the diff](https://github.com/digitalcraftsman/hugo-material-docs/commit/1f8393a8d4ce1b8ee3fc7d87be05895c12810494) 15 | 16 | ### 22nd March 2016 17 | 18 | #### Changing setup for Google Analytics 19 | 20 | Formerly, the tracking id for Google Analytics was set like below: 21 | 22 | ```toml 23 | [params] 24 | google_analytics = ["UA-XXXXXXXX-X", "auto"] 25 | ``` 26 | 27 | Now the theme uses Hugo's own Google Analytics config option.

The port of the original [Material theme](https://github.com/squidfunk/mkdocs-material) has replicated nearly all of its features. A few are still missing but I've good news: the Hugo community is actively working on this issues. Maybe with the next release of Hugo we can abandon this list. Stay tuned. 8 | 9 | ## Localization 10 | 11 | Currently, it is possible to collect all strings in a single place for easy customization. However, this only enables you to define all strings in a single language. This approach is quite limiting in terms of localization support. Therefore, I decided to wait for a native integration. This way we can avoid a second setup of all strings in your website. 12 | 13 | Keep an eye on [#1734](https://github.com/spf13/hugo/issues/1734). 14 | 15 | ## Search 16 | 17 | Beside third-party services, some hacky workarounds and Grunt-/Gulp-based scripts that only require unnecessary dependencies, future versions of Hugo will support the generation of a content index as a core feature. 18 | 19 | This approach plays well with this theme since MkDocs does the same. 20 | 21 | Keep an eye on [#1853](https://github.com/spf13/hugo/pull/1853). 22 | 23 | ## Contributing 24 | 25 | Did you found an bug or you would like to suggest a new feature?
