Question: When was Weep Not, Child first published?

Read the following text and answer briefly.

Context 1: Weep Not, Child is a 1964 novel by Kenyan author Ngũgĩ wa Thiong'o  It was his first novel, published in 1964 under the name James Ngugi  It was among the African Writers Series  It was the first English language|English novel to be published by an East African  Thiong'o's works deal with the relationship between Africans and white settlers in colonial Kenya, and are heavily critical of colonial rule  Specifically, Weep Not, Child deals with the Mau Mau Uprising, and "the bewildering dispossession of an entire people from their ancestral land " Ngũgĩ wrote the novel while he was a student at Makerere University 

The book is divided into two parts and eighteen chapters  Part one deals mostly with the education of Njoroge, while part two deals with the rising Mau Mau movement 

Plot summary

Njoroge, a little boy, is urged to attend school by his mother  He is the first one of his family able to go to school  His family lives on the land of Jacobo, an African made rich by his dealings with white settlers, namely Mr  Howlands, the most powerful land owner in the area  Njoroge's brother Kamau works as an apprentice to a carpenter, while Boro, the eldest living son, is troubled by his experiences while in forced service during World War II, including witnessing the death of his elder brother  Ngotho, Njoroge's father and a respected man in the surrounding area, tends Mr  Howlands' crops, but is motivated by his passion to preserve his ancestral land, rather than for any compensation or loyalty 

One day, black workers call for a strike to obtain higher wages  Ngotho is ambivalent about participating in the strike because he fears he will lose his job  However, he decides to go to the gathering, even though his two wives do not agree  At the demonstration, there are calls for higher wages  Suddenly, the white police inspector brings Jacobo to the gathering to pacify the native people  Jacobo tries to put an end to the strike  Ngotho attacks Jacobo, and the result is a riot where two people are killed  Jacobo survives and swears revenge  Ngotho loses his job and Njoroge’s family is forced to move  Njoroge’s brothers fund his education and seem to lose respect for their father 

Mwihaki, Jacobo's daughter and Njoroge's best friend, enters a girls' only boarding school, leaving Njoroge relatively alone  He reflects upon her leaving, and realizes that he was embarrassed by his father's actions towards Jacobo  For this reason, Njoroge is not upset by her exit and their separation  Njoroge switches to another school 

For a time, everyone's attention is focused on the upcoming trial of Jomo Kenyatta – a revered leader of the movement  Many blacks think that he is going to bring forth Kenya’s independence  But Jomo loses the trial and is imprisoned  This results in further protests and greater suppression of the black population 

Jacobo and a white landowner, Mr  Howlands, fight against the rising activities of the Mau Mau, an organization striving for Kenyan economic, political, and cultural independence  Jacobo accuses Ngotho of being the leader of the Mau Mau and tries to imprison the whole family  Meanwhile, the situation in the country is deteriorating  Six black men are taken out of their houses and executed in the woods 

One day Njoroge meets Mwihaki again, who has returned from boarding school  Although Njoroge had planned to avoid her due to the conflict between their fathers, their friendship is unaffected  Njoroge passes an important exam that allows him to advance to High School  His village is proud of him, and collects money to pay Njoroge's High School tuition 

Several months later, Jacobo is murdered in his office by a member of the Mau Mau  Mr  Howlands has Njoroge removed from school for questioning  Both father and son are brutally beaten before release and Ngotho is left barely alive  Although there doesn't seem to be a connection between Njoroge's family and the murder, it is eventually revealed that Njoroge's brothers are behind the assassination, and that Boro is the real leader of the Mau Mau  Ngotho soon dies from his injuries and Njoroge finds out that his father was protecting his brothers  Kamau has been imprisoned for life  Only Njoroge and his two mothers remain free, and Njoroge is left as the sole provider of his two mothers  Njoroge fears that he cannot make ends meet; he gives up hope of continuing in school and loses faith in God 

Njoroge asks Mwihaki's for support, but she is angry because of her father’s death  When he finally pledges his love to her, she refuses to leave with him, realizing her obligation to Kenya and her mother  Njoroge decides to leave town and makes an attempt at suicide; however, he fails when his mothers find him before he is able to hang himself  The novel closes with Njoroge feeling hopeless, and ashamed of cowardice 

Characters in Weep Not, Child
 Njoroge: the main character of the book whose main goal throughout the book is to become as educated as possible 
 Ngotho: Njoroge's father  He works for Mr Howlands and is respected by him until he attacks Jacobo at a workers strike  He is fired and the family is forced to move to another section of the country  Over the course of the book his position as the central power of the family weakened, to the point where his self-realization that he has spent his whole life waiting for the prophecy (that proclaims the blacks will be returned their land) to come true rather than fighting for Kenyan independence, leads to his depression 
 Nyokabi and Njeri: the two wives of Ngotho  Njeri is Ngotho's first wife, and mother of Boro, Kamau, and Kori  Nyokabi is his second wife, and the mother of Njoroge and Mwangi 
 Njoroge has four brothers: Boro, Kamau, Kori and Mwangi (who is Njoroge's only full brother, who died in World War II) 
 Boro: Son of Njeri who fights for the Allies in World War II  Upon returning his anger against the colonial government is compounded by their confiscation of the his land  Boro's anger and position as eldest son leads him to question and ridicule Ngotho, which eventually defeats their father's will (upon realizing his life was wasted waiting and not acting)  It is eventually revealed that Boro is the leader of the Mau Mau (earlier alluded to as "entering politics") and murders Mr Howlands  He is caught by police immediately after and is scheduled to be executed by the book's end  It is highly likely that it is also Boro who kills Jacobo 
 Mwihaki: Njoroge's best friend (and later develops into his love interest)  Daughter of Jacobo  When it is revealed that his family killed Jacobo (most likely Boro), Mwihaki distances herself from Njoroge, asking for time to mourn her father and care for her mother 
 Jacobo: Mwihaki's father and an important landowner  Chief of the village 
 Mr  Howlands: A white settler who emigrated to colonial Kenya and now owns a farm made up of land that originally belonged to Ngotho's ancestors  Has three children: Peter who died in World War II before the book's beginning, a daughter who becomes a missionary, and Stephen who met Njoroge while the two were in high school 

Themes and motifs
Weep Not, Child integrates Gikuyu mythology and the ideology of nationalism that serves as catalyst for much of the novel's action  The novel explores the negative aspects of colonial rule over Kenya  Njoroge's aspiration to attend university is frustrated by both the violence of the Mau Mau rebels and the violent response of the colonial government  This disappointment leads to his alienation from his family and ultimately his suicide attempt 

The novel also ponders the role of saviours and salvation  The author notes in his The River Between: "Salvation shall come from the hills  From the blood that flows in me, I say from the same tree, a son shall rise  And his duty shall be to lead and save the people " Jomo Kenyatta, the first prime minister of Kenya, is immortalised in Weep Not, Child  The author says, "Jomo had been his (Ngotho's) hope  Ngotho had come to think that it was Jomo who would drive away the white man  To him, Jomo stood for custom and traditions purified by grace of learning and much travel " Njoroge comes to view Jomo as a messiah who will win the struggle against the colonial government

本地搭建以太坊私有网络-基于Ganache和MetaMask
本文主要介绍如何使用Ganache，在本地搭建以太坊私有网络，并进行简单的测试。
Ganache用于搭建私有网络。在开发和测试环境下，Ganache提供了非常简便的以太坊私有网络搭建方法，通过可视化界面可以直观地设置各种参数、浏览查看账户和交易等数据。
下载地址为：https://truffleframework com/ganache/
MetaMask用于测试私有网络。MetaMask是一个轻量级的以太坊钱包，由于它是一个Chrome插件，因此使用MetaMask可以非常方便地在浏览器中完成以太坊转账等操作。
下载地址为：https://www metamask io
安装、启动Ganache
1  使用安装包安装即可。
2  打开程序后，会显示以下界面，用户可以查看账户（默认创建10个账户）、区块、交易和日志。
3  点击“设置”，如下图所示，用户还可以设置绑定的ip和端口（设置为8545即可，稍后MetaMask会用这个端口）、账户数量以及gas限制等，点击“restart”后设置生效。
此时，Ganache已经在本机运行了一个以太坊私有网络，并绑定了8545端口。
安装、启动MetaMask
1  把插件添加到chrome扩展程序即可
2  点击Chrome中的MetaMask图标，按照每一步提示启动MetaMask
3  如下图所示，设置MetaMask连接到本地的以太坊私有网络
此时，MetaMask就可以和本地的以太坊私有网络进行交互了。
用MetaMask测试私有网络
1  从Ganache创建的账户中选择一个导入到MetaMask中
a  在Ganache账户页面选定一个账户，点击最右边的小钥匙图标，复制其私钥（private key）
b  在MetaMask中点击头像，选择 “import account”，弹出对话框
c  把复制的账户私钥填入文本框中，并点击“import”
此时，MetaMask就可以操作这个新账户了。
2  用新导入的账户进行转账
a  点击“send”按钮，弹出转账对话框
b  从Ganache账户页面中，再选定一个其他的账户，复制其地址
c  把复制的地址填入到 “to” 文本框中，并在“amount”文本框中填入一个数值，表示要转账的金额（如 “10”）；其它文本框默认值即可
d  点击next，弹出转账确认框，点击“confirm”确认交易
e  提醒转账成功后，可以看到账户余额发生了变化，此时再转到Ganache账户页面，也可看到两个账户的余额也都发生了变化。
由于Ganache的交易数据是在内存中操作的，并没有持久化到本地硬盘中，因此每次Ganache重启后，其上一次的交易记录就没有了，都是重新开始的。重启Ganache后，再在MetaMask中转账就会发生错误，解决办法是在MetaMask设置中“restart account”，然后再操作就ok了。
如果想保留Ganache每一次运行时的交易数据，以便下一次继续使用，可以使用命令行的形式ganache-cli启动Ganache，并指定数据存储目录

献给那些安装remix-ide一直不成功的windows用户
首先找到编译器git地址，https://github com/ethereum/remix-ide；
进来后有安装步骤
/home/water/下载/3486521-922a751008a61222 png
remix-ide png
如果我们电脑上没有node js先登录下面的网址安装
因为安装的过程中需要的权限功能比较多所以得用管理员执行powershell 不建议使用cmd操作
安装好之后查看自己的 输入命令npm -v ，查看npm版本号如果低于6 1 0。输入 npm install npm@latest -g 升级npm版本号，这个版本比较稳定
然后执行npm install remix-ide -g
接着执行remix-ide
登录http://127 0 0 1:8080
如果不成功 执行 npm install --global --production windows-build-tools
然后再执行上面的步骤八成就可以了，remix-ide需要的环境还挺多

有趣的椭圆曲线加密
摘要: 一、概述 椭圆曲线加密算法依赖于椭圆曲线理论，后者理论涵盖的知识比较深广，而且涉及数论中比较深奥的问题。经过数学家几百年的研究积累，已经有很多重要的成果，一些很棘手的数学难题依赖椭圆曲线理论得以解决（比如费马大定理）。 本文涉及的椭圆曲线知识只是抽取与密码学相关的很小的一个角落，涉及到很浅的理论的知识，同时也是一点比较肤浅的总结和认识，重点是利用椭圆曲线结合数学技巧阐述加密算法的过程和原理。 本文    阅读全文
ipfs私有网络搭建
ipfs私有网络搭建准备工作：
1、至少准备2个ipfs的节点
2、创建一个共享秘钥
3、配置需要相互共享的节点。
一、准备IPFS节点。
1、准备两台linux节点，我测试的系统是Ubuntu 18 04 LTS（点击可以下载）。
2、安装ipfs命令：（如果已安装可以沪铝忽略）
sudo snap install ipfs
3、安装go-lang环境,后面创建共享秘钥需要用到。（如果已安装请忽略）
sudo apt-get install golang
4、安装git。（如果已经安装请忽略）
两台linux服务器均完成ipfs安装之后第一步准备工作便已完成。
二、创建共享秘钥
1、到github上面下载秘钥生成工具go-ipfs-swarm-key-gen。
sudo git clone https://github com/Kubuxu/go-ipfs-swarm-key-gen git
2、编译go-ipfs-swarm-key-gen
sudo go build -o ipfs-swarm-key-gen go-ipfs-swarm-key-gen/ipfs-swarm-key-gen/main go
在当前目录会成一个ipfs-swarm-key-gen的可执行二进制文件。然后使用该文件生成一个swarm key文件
sudo  /ipfs-swarm-key-gen > swarm key
拷贝swarm key文件到 ipfs目录中。（注意使用snap安装ipfs那么 ipfs目录在~/snap/ipfs/目录下，例如我的是在~/snap/ipfs/589/下）。
三、配置相互共享的私有网络
1、分别初始化两个ipfs节点。
ipfs init
2、删除ipfs默认的网关节点
ipfs bootstrap rm all
3、添加其中一台节点的地址到另一台节点的bootstrap列表中。
3 1执行ipfs id查看ipfs节点的ID值。
ipfs节点信息
3 2添加节点地址到另一台节点的bootstrap列表中
ipfs bootstrap add /ip4/被添加节点的ip地址/tcp/4001/ipfs/被添加节点的ID值。
至此ipfs私有网络搭建完毕

Question: 如何安装并启动Ganache?

Read the following text and answer briefly.

Context 4:  This is consistent with the numerical simulation results presented in the main text, see Fig  \ref{fig:ising}(b) therein 

\begin{figure}[th]
\vspace*{0 2 cm}

 \includegraphics[width=10 cm]{ /compare_binder pdf}

\caption{Comparison between the temporal evolution of the Binder cumulants $g$ corresponding to the $12^{th}$ transverse mode, $i e ,$ with $n_\perp =12,$ in the LG (lowest curve), IDLG and RDLG (two upper curves) on a $32 \times 32$ lattice  \label{fig:b}}
 \label{fig:binder}
\end{figure}


The emergence of this new value $1/10$ of the exponent $\alpha$ must be traced back to the non-Gaussian nature of higher fluctuating modes in the LG  In fact, even though the lowest mode behaves identically in all the three models we considered,  characterized by the same behaviour of $m$, higher modes show a significant difference in the non-driven case   


To illustrate this, we measured the Binder cumulants of higher modes which is defined  analogously to Eq ~(11), using transverse modes other than the first, i e , with $\mu=\tilde \sigma(0,2 \pi n_\bot/L_\bot)$ and $n_\bot>1 $  
 Figure \ref{fig:b} compares the same for all the three lattice gases for the mode with $n_\perp =12$ on a $32 \times 32$ lattice  Clearly, the curve corresponding to the LG (lowest, blue) departs from Gaussian behaviour $g=0$ (in practice, $e g ,$ $|g| \lesssim 0 005,$ corresponding to the shaded gray area) much earlier than it does for the IDLG  or RDLG (two upper curves, red and green respectively) 

Accordingly, the different dynamical behaviour of $O$, which involves a sum over all modes, can be attributed to the non-Gaussian nature of the higher modes in the LG  
Such a departure is not entirely surprising  In fact, for higher modes, mesoscopic descriptions such as the ones in Eqs  \eqref{eq:L-DLG} or \eqref{eq:g_evol} are not expected to hold, while the anisotropy at the microscopic level could be the mechanism leading to the Gaussianity of higher modes in the driven models
