<div class="post-text" itemprop="text"> <p>How do I embed a channel in a struct in <a href="http://en.wikipedia.org/wiki/Go_%28programming_language%29" rel="nofollow">Go</a>?</p> <p>Why the inconsistency between the map syntax:</p> <pre><code>var m map[string]int </code></pre> <p>and channel,</p> <pre><code>var m chan int </code></pre> <p>?</p> <p>To clarify, in Go it is possible to embed a type in another type. The embedder type gains access to all the methods defined on the embedded type, but it is also possible to refer to the embedded type explicitly by the name of its type. Therefore, the inconsistency between the map type declaration and channel type declaration is confusing for someone who would like to refer to an embedded channel type.</p> </div>

<div class="post-text" itemprop="text"> <p>Let us say that we have a fairly complicated <code>struct</code> with numerous fields, that I need to sort in several places according to different criteria, e.g.</p> <pre><code>type MySuperType struct { x0, x1, x2, x3 xType // possibly even more fields } // sort 1: ascending x0, then descending x1, then more stuff // sort 2: if x4==0 then applyCriteria2a else applyCriteria2b func f1(mySuperSlice []MySuperType) { // sort 'myList' according sort #1 // do something with the sorted list } func f2(mySuperSlice []MySuperType) { // sort 'myList' according sort #2 // do something with the sorted list } func f3(mySuperSlice []MySuperType) { // sort 'myList' according sort #1, note: we use sort #1 again! // do something with the sorted list } </code></pre> <p><strong>Proposed solution 1:</strong><br> Create a new type (alias of <code>[]MySuperType</code>) that implements <code>sort.Interface</code> for each sorting criteria required.<br> Problems: (i) there is some duplicated code, as the functions <code>Len</code> and <code>Swap</code> are going to be identical (ii) there is going to be a bunch of new types lying around that do not help with the overall readability of the program --- these new types don't really represent anything, plus the only thing that really matters is the <code>Less</code> function.</p> <p><strong>Proposed solution 2:</strong><br> Use <code>sort.Slice</code><br> It would be the perfect solution (see <a href="https://stackoverflow.com/a/42872183/3923424">this answer</a>), but from my understanding, the sorting function has to be specified inline (I get an error <code>invalid receiver type []T ([]T is an unnamed type)</code> when I tried to define it elsewhere, which means that I need to define an alias for <code>[]T</code> and we are back to solution 1).<br> Now, the problem with defining the function inline is that (i) given the complexity of <code>MySuperType</code>, the function can be very long and (ii) the functions are going to be duplicated in several place (e.g. in <code>f1</code> and <code>f3</code> in my example above) -- much more annoying that in solution 1 as the sorting functions can be long and complex.<br> _{Note: (i) would not be that much of an issue if we did not have (ii) actually}</p> <p><strong>Question:</strong><br> Given my current understanding and knowledge of Go, I would use solution 1.<br> But does anyone knows a different approach that elegantly solves this problem or suggestions to improve the drawbacks listed above?</p> </div>

Why can't it be named? I can name it outside function and also pass them as arguments with them being named.</p> <p>It does not work. So I just passed []Sentence as an argument and solve the problem that I need to. But when passing them as arguments, I had to return a new copy.</p> <p>I still think that it would be nice if I can just let the function receive the struct array and does not have to return anything.</p> <p>Like below:</p> <pre><code>func (S *[]Sentence)MarkC() { for _, elem := range S { elem.mark = "C" } } var arrayC []Sentence for i:=0; i&lt;5; i++ { var new_st Sentence new_st.index = i arrayC = append(arrayC, new_st) } //MarkC(arrayC) //fmt.Println(arrayC) //Expecting [{0 C} {1 C} {2 C} {3 C} {4 C}] //but not working </code></pre> <p>It is not working either with []Sentence.</p> <p>Is there anyway that I can make a function receive Struct array?</p> </div>

我是嵌入式刚开学的新手 在我们嵌入式课程上面，我们通过IAR对NXP LPC2478进行开发和编译学习。。 课程中收到了一些实验例程，其中就包括LCD 和 SD卡读取的相关例子。。 在学习中，我希望把SD卡读写和LCD显示整合在一起，能实现读取SD卡中数据显示在LCD屏幕的功能。。 在两个工程合并中，我用LCD的例子为基础，依次添加SD卡中相关的.c文件和.h文件。。。在添加SD卡的例子过程中，出现的未知错误，添加mmc.c的时候编译出错，出错提示如下 Error[Pa055]: expected a type attribute C:\Program Files\IAR Systems\Embedded Workbench 5.4 Evaluation\arm\inc\NXP\iolpc2460.h 2734 Error[Pe079]: expected a type specifier C:\Program Files\IAR Systems\Embedded Workbench 5.4 Evaluation\arm\inc\NXP\iolpc2460.h 2734 Error[Pe040]: expected an identifier C:\Program Files\IAR Systems\Embedded Workbench 5.4 Evaluation\arm\inc\NXP\iolpc2460.h 2734 Error[Pe168]: a function type is not allowed here C:\Program Files\IAR Systems\Embedded Workbench 5.4 Evaluation\arm\inc\NXP\iolpc2460.h 2734 Error[Pe147]: declaration is incompatible with "union <unnamed> volatile _A_<error>" (declared at line 4079) C:\Program Files\IAR Systems\Embedded Workbench 5.4 Evaluation\arm\inc\NXP\iolpc2460.h 4080 等这几类错误，一共一百多个错误，查找的源头是 Embedded Workbench 5.4 Evaluation\arm\inc\NXP\iolpc2460.h 在添加各个.c时编译时没有问题的，但是在main函数 #include “mmc.h” 时 就是会出现错误。 我在整合时看到，SD卡的例子用的头文件时<nxp/iolpc2468.h> 而 LCD则用的是另外的头文件“LPC23XX.h”，“LPC2468.h” 所以在此希望高人能帮助下我，谢谢。。

一、前言 照着大学的SQL server来学

昨天早上通过远程的方式 review 了两名新来同事的代码，大部分代码都写得很漂亮，严谨的同时注释也很到位，这令我非常满意。但当我看到他们当中有一个人写的 switch 语句时，还是忍不住破口大骂：“我擦，小王，你丫写的 switch 语句也太老土了吧！” 来看看小王写的代码吧，看完不要骂我装逼啊。 private static String createPlayer(PlayerTypes p...

华为面试整体流程大致分为笔试，性格测试，面试，综合面试，回学校等结果。笔试来说，华为的难度较中等，选择题难度和网易腾讯差不多。最后的代码题，相比下来就简单很多，一共3道题目，前2题很容易就AC，题目已经记不太清楚，不过难度确实不大。最后一题最后提交的代码过了75%的样例，一直没有发现剩下的25%可能存在什么坑。 笔试部分太久远，我就不怎么回忆了。直接将面试。 面试 如果说腾讯的面试是挥金如土...

最近有个老铁，告诉我说，上班一个月，后悔当初着急入职现在公司了。他之前在美图做手机研发，今年美图那边今年也有一波组织优化调整，他是其中一个，在协商离职后，当时捉急找工作上班，因为有房贷供着，不能没有收入来源。所以匆忙选了一家公司，实际上是一个大型外包公司，主要派遣给其他手机厂商做外包项目。**当时承诺待遇还不错，所以就立马入职去上班了。但是后面入职后，发现薪酬待遇这块并不是HR所说那样，那个HR自...

原博客再更新，可能就没了，之后将持续更新本篇博客。

提到“程序员”，多数人脑海里首先想到的大约是：为人木讷、薪水超高、工作枯燥…… 然而，当离开工作岗位，撕去层层标签，脱下“程序员”这身外套，有的人生动又有趣，马上展现出了完全不同的A/B面人生！ 不论是简单的爱好，还是正经的副业，他们都干得同样出色。偶尔，还能和程序员的特质结合，产生奇妙的“化学反应”。 @Charlotte：平日素颜示人，周末美妆博主 大家都以为程序媛也个个不修边幅，但我们也许...

私下里，有不少读者问我：“二哥，如何才能写出一份专业的技术简历呢？我总感觉自己写的简历太烂了，所以投了无数份，都石沉大海了。”说实话，我自己好多年没有写过简历了，但我认识的一个同行，他在阿里，给我说了一些他当年写简历的方法论，我感觉太牛逼了，实在是忍不住，就分享了出来，希望能够帮助到你。 01、简历的本质 作为简历的撰写者，你必须要搞清楚一点，简历的本质是什么，它就是为了来销售你的价值主张的。往深...

有小伙伴问松哥这个问题，他在上海某公司，在离职了几个月后，前公司的领导联系到他，希望他能够返聘回去，他很纠结要不要回去？ 俗话说好马不吃回头草，但是这个小伙伴既然感到纠结了，我觉得至少说明了两个问题：1.曾经的公司还不错；2.现在的日子也不是很如意。否则应该就不会纠结了。 老实说，松哥之前也有过类似的经历，今天就来和小伙伴们聊聊回头草到底吃不吃。 首先一个基本观点，就是离职了也没必要和老东家弄的苦...

二哥，有个事想询问下您的意见，您觉得应届生值得去外包吗？公司虽然挺大的，中xx，但待遇感觉挺低，马上要报到，挺纠结的。

当HR压你价，说你只值7K时，你可以流畅地回答，记住，是流畅，不能犹豫。 礼貌地说：“7K是吗？了解了。嗯~其实我对贵司的面试官印象很好。只不过，现在我的手头上已经有一份11K的offer。来面试，主要也是自己对贵司挺有兴趣的，所以过来看看……”（未完） 这段话主要是陪HR互诈的同时，从公司兴趣，公司职员印象上，都给予对方正面的肯定，既能提升HR的好感度，又能让谈判气氛融洽，为后面的发挥留足空间。...

终于懂了TCP和UDP协议区别

编程语言层出不穷，从最初的机器语言到如今2500种以上的高级语言，程序员们大呼“学到头秃”。程序员一边面临编程语言不断推陈出新，一边面临由于许多代码已存在，程序员编写新应用程序时存在重复“搬砖”的现象。 无代码/低代码编程应运而生。无代码/低代码是一种创建应用的方法，它可以让开发者使用最少的编码知识来快速开发应用程序。开发者通过图形界面中，可视化建模来组装和配置应用程序。这样一来，开发者直...

前几天我们公司做了一件蠢事，非常非常愚蠢的事情。我原以为从学校出来之后，除了找工作有测试外，不会有任何与考试有关的事儿。 但是，天有不测风云，公司技术总监、人事总监两位大佬突然降临到我们事业线，叫上我老大，给我们组织了一场别开生面的“考试”。 那是一个风和日丽的下午，我翘着二郎腿，左手端着一杯卡布奇诺，右手抓着我的罗技鼠标，滚动着轮轴，穿梭在头条热点之间。 “淡黄的长裙~蓬松的头发...
