Run this to set your project up with a simple Gulp config.
```sh
./bin/rails generate npm_pipeline:gulp
```
## Manual setup
If you don't want to use the generator, here's what it does.
#### package.json
> Set up `gulp`, `gulp-cli`, and some basic Gulp plugins.
```sh
npm init --yes
npm install --save-dev gulp gulp-cli gulp-concat
```
_See:_ [sample package.json](../lib/generators/npm_pipeline/gulp/package.json)
#### gulpfile.js
> Set it up to watch source files in `app/gulp`, then put built files into `vendor/assets`.
_See:_ [sample gulpfile.js](../lib/generators/npm_pipeline/gulp/gulpfile.js)
#### .gitignore
> Set it up to ignore Gulp's built files.
```
/node_modules
/vendor/assets/stylesheets/gulp
/vendor/assets/javascripts/gulp
```
#### app/assets/stylesheets/application.css
> Set it up to include Gulp's built files. This will load from `vendor/assets/stylesheets/gulp/app.css`, as built by Gulp.
```css
/*
*= require gulp/app
*/
```
#### app/assets/javascripts/application.js
> Set it up to include Gulp's built files. This will load from `vendor/assets/javascripts/gulp/app.js`, as built by Gulp.
```css
//= require gulp/app
```
#### app/gulp/
> Put your source files into `app/gulp`. For instance:
* `app/gulp/example.css`
```css
* { color: blue }
```
* `app/gulp/example.js`
```js
alert('it works!')

Markdown | UTF-8 | 14,624 | 3.890625 | 4 | [] | no_license | ## Chapter 3 线性方程组的解法
### 3.1 基本概念
1、$n$元矩阵表示：$Ax=B$
2、解：$x_1^*,\cdots,x^*_n$
3、解法：
- 直接法：用计算公式直接求出
- 迭代法：用迭代公式计算出满足精度要求近似解（逼近）
### 3.2 线性方程组的迭代解法
*类似非线性方程求根的简单迭代法，Jacobi迭代法、Seidel迭代法及Sor法等。*
基本思想：将线性方程组$Ax=B$等价变形为$x=Bx+g$，然后构造向量迭代公式：
$x^{(k+1)}=Bx^{(k)}+g,k=0,1,2,\cdots$
给定一个初始向量$x^{(0)}$，带入迭代公式计算$x^{(1)},x^{(2)},\cdots$
#### 3.2.1 迭代公式构造
1、Jacobi迭代公式构造
$\left\{\begin{array}{c}
a_{11}x_1+a_{12}x_2+\cdots+a_{1n}x_n=b_1 \\
a_{21}x_1+a_{22}x_2+\cdots+a_{2n}x_n=b_2 \\
\vdots \\
a_{n1}x_1+a_{n2}x_2+\cdots+a_{nn}x_n=b_n
\end{array}
\right.\Leftrightarrow \left\{\begin{array}{c}
x_1=\dfrac{1}{a_{11}}(b_1-a_{12}x_2-a_{13}x_3-\cdots-a_{1n}x_n)\\
x_2=\dfrac{1}{a_{22}}(b_2-a_{21}x_1-a_{23}x_3-\cdots-a_{2n}x_n)\\
\vdots \\
x_n=\dfrac{1}{a_{nn}}(b_n-a_{n1}x_1-a_{n2}x_2-\cdots-a_{nn-1}x_{n-1})
\end{array}
\right.$
写成Jacobi迭代格式：
$\left\{\begin{array}{c}
x_1^{(k+1)}=\dfrac{1}{a_{11}}(b_1-a_{12}x_2^{(k)}-a_{13}x_3^{(k)}-\cdots-a_{1n}x_n^{(k)})\\
x_2^{(k+1)}=\dfrac{1}{a_{22}}(b_2-a_{21}x_1^{(k)}-a_{23}x_3^{(k)}-\cdots-a_{2n}x_n^{(k)})\\
\cdots \\
x_n^{(k+1)}=\dfrac{1}{a_{nn}}(b_n-a_{n1}x_1^{(k)}-a_{n2}x_2^{(k)}-\cdots-a_{nn-1}x_{n-1}^{(k)})
\end{array}
\right.$
2、 Seidel迭代公式构造（Jacobi的改进，但不能取代）
$\left\{\begin{array}{c}
x_1^{(k+1)}=\dfrac{1}{a_{11}}(b_1-a_{12}x_2^{(k)}-a_{13}x_3^{(k)}-\cdots-a_{1n}x_n^{(k)})\\
x_2^{(k+1)}=\dfrac{1}{a_{22}}(b_2-a_{21}x_1^{(k+1)}-a_{23}x_3^{(k)}-\cdots-a_{2n}x_n^{(k)})\\
\cdots \\
x_n^{(k+1)}=\dfrac{1}{a_{nn}}(b_n-a_{n1}x_1^{(k+1)}-a_{n2}x_2^{(k+1)}-\cdots-a_{nn-1}x_{n-1}^{(k+1)})
\end{array}
\right.$
3、Sor迭代公式构造（Seidel的改进，*超松弛迭代法*）
用Seidel迭代格式算出的$x^{(k+1)}$记为$\tilde{x}^{(k+1)}$得到增量：$\Delta x=\tilde{x}^{(k+1)}-x^{(k)}$，做增量加速处理（$\omega$松弛因子）
$x^{(k+1)}=x^{(k)}+\omega\Delta x=(1-\omega)x^{(k)}+\omega\tilde{x}^{(k+1)}$
#### 3.2.2 向量迭代格式
1、Jacobi向量迭代格式
记：$L=\left[\begin{array}{cccc} 0&0&\cdots&0\\ -a_{21}&0&\cdots&0\\\vdots&\vdots&\ddots&\vdots\\-a_{n1}&-a_{n2}&\cdots&0\end{array}\right]$，$U=\left[\begin{array}{cccc} 0&-a_{12}&\cdots&-a_{2n}\\0&0&\cdots&-a_{2n}\\\vdots&\vdots&\ddots&\vdots\\0&0&\cdots&0\end{array}\right]$，$D=\left[\begin{array}{cccc} a_{11}\\&a_{22}\\&&\ddots\\&&&a_{nn}\end{array}\right]$，$x^{(k)}=\left[\begin{array}{c} x_{1}^{(k)}\\x_{2}^{(k)}\\\vdots\\x_{n}^{(k)}\end{array}\right]$，$b=\left[\begin{array}{c}b_1\\b_2\\\vdots\\b_n\end{array}\right]$
有：
$
\left[\begin{array}{c} x_{1}^{(k+1)}\\x_{2}^{(k+1)}\\\vdots\\x_{n}^{(k+1)}\end{array}\right]=\left[\begin{array}{cccc} a_{11}^{-1}\\&a_{22}^{-1}\\&&\ddots\\&&&a_{nn}^{-1}\end{array}\right]\left[\begin{array}{cccc} 0&-a_{12}&\cdots&-a_{1n}\\ -a_{21}&0&\cdots&-a_{2n}\\\vdots&\vdots&\ddots&\vdots\\-a_{n1}&-a_{n2}&\cdots&0\end{array}\right]\left[\begin{array}{c} x_{1}^{(k)}\\x_{2}^{(k)}\\\vdots\\x_{n}^{(k)}\end{array}\right]+\left[\begin{array}{c}b_1\\b_2\\\vdots\\b_n\end{array}\right]
$
$x^{(k+1)}=D^{-1}(L+U)x^{(k)}+D^{(-1)}b\to x^{(k+1)}=B_Jx^{(k)}+g_J$，$B_J$称为Jacobi迭代矩阵。
2、Seidel向量迭代格式
$x^{(k+1)}=D^{-1}(Lx^{(k+1)}+Ux^{(k)}+b)\Rightarrow x^{(k+1)}=(D-L)^{-1}Ux^{(k)}+(D-L)^{-1}b\to x^{(k+1)}=B_Sx^{(k)}+g_S$，$B_S$称为Seidel迭代矩阵。
3、Sor向量迭代格式
$x^{(k+1)}=B_{\omega}x^{(k)}+g_{\omega}$
$B_{\omega}=(D-\omega L)^{-1}[(1-\omega)D+\omega U],g_{\omega}=\omega(D-\omega L)^{-1}b$
上面三种向量迭代格式可统一写成：
$x^{(k+1)}=Bx^{(k)}+g$，$B$为迭代矩阵。
#### 3.2.3 范数
*收敛的本质是距离趋于0，两个实数的距离是绝对值，向量的距离用**范数**描述。*
1、范数定义
设$L$是数域$K$上的一个线性空间，如果定义在$L$上的实值函数$P(x)$满足：
1）$\forall x\in L\Rightarrow P(x)\ge 0,P(x)=0\Leftrightarrow x=0$；
2）$\forall x\in L,\lambda \in K\Rightarrow P(\lambda x)=|\lambda|P(x)$；
3）$\forall x,y\in L\Rightarrow P(x+y)\le P(x)+P(y)$
则称$P$是$L$的范数，$P(x)$为$x$的一个范数。记$P(x)=||x||_p=||x||$则
1）$||x||\ge 0$且$||x||=0\Leftrightarrow x=0$；
2）$||\lambda x||=|\lambda|\cdot||x||$；
3）$||x+y||\le||x||+||y||$
2、数值分析中常用的线性空间
1）$n$维向量空间 $R^n$
2）矩阵空间 $R^{m\times n}$
3）连续函数空间 $C[a,b]=\{f(x)|f(x)在[a,b]连续\}$
3、$R^{n\times n}$中范数矩阵定义 略
#### 3.2.4 数值分析中的范数
1、$R^n$中的向量范数
1）$||x||_1=\sum\limits_{k=1}^n|x_k|$
2）$||x||_2=\sqrt{\sum^n\limits_{k=1}x_k^2}$
3）$||x||_{\infty}=\max\limits_{1\le k\le n}|x_k|$
式中向量$x=(x_1,\cdots,x_n)^T$
2、矩阵算子范数
由范数相容性：$||Ax||\le ||A||||x||$，
矩阵$A$算子范数定义：
$||A||_P=\max\limits_{x\in R^n\\x\neq0}\dfrac{||Ax||_P}{||x||_P}$，算子范数$\Rightarrow$矩阵范数，反向不可。
3、$R^{n\times n}$中的矩阵范数
1）列范数：$||A||_1=\max\limits_{1\le j\le n}\sum^n\limits_{i=1}|a_{ij}|$
2）行范数：$||A||_\infty=\max\limits_{1\le i\le n}\sum^n\limits_{j=1}|a_{ij}|$
3）$F$范数：$||A||_F=\sqrt{\sum^n\limits_{i,j=1}a^2_{ij}}$，不是算子范数
4）2范数：$||A||_2=\sqrt{\lambda_{\max}}$，$\lambda_{\max}$是$A^TA$的最大特征值
4、范数等价与向量极限
1）范数等价：$m||x||_p\le||x||_q\le M||x||_p,\forall x\in L$
$R^n$上所有范数等价。
2）$\lim\limits_{k\to\infty}x^{(k)}=x^*\Leftrightarrow \lim\limits_{k\to\infty}||x^{(k)}-x^*||=0$
#### 3.2.5 谱半径
1、定义：$A\in R^{n\times n},\lambda_k$是$A$的特征值，$k=1,2,\cdots,n$，称$\rho(A)=\max\limits_{1\le k\le n}|\lambda_k|$为矩阵$A$的谱半径。
2、谱半径与矩阵范数的关系
**定理1** $\rho(A)\le||A||$，$||\cdot||$是任意的矩阵范数。
3、一些关于谱半径的结论
1）$\rho(A^k)=[\rho(A)]^k$
2）$\forall \varepsilon>0$，存在一种矩阵范数使得$||A||\le\rho(A)+\varepsilon$
3）当矩阵$A$对称时，$\rho(A)=||A||_2$
4）当矩阵$A$为方阵时有$\lim\limits_{k\to\infty}A^k=0\Leftrightarrow \rho(A)<1$
#### 3.2.6 迭代收敛定理
1、迭代收敛定理
**定理2** $x^{(k+1)}=Bx^{(k)}+g$对任意$x^{(0)}$都收敛$\Leftrightarrow \rho(B)<1$
2、迭代收敛判别条件
**判别条件1** （充分条件）若存在迭代矩阵$B$的某种矩阵范数满足$||B||<1$，则$\forall x^{(0)}\in R^n,x^{(k+1)}=Bx^{(k)}+g$产生的迭代序列都收敛到其不动点$x^*$。
**判别条件2** 若$A$为严格对角占优矩阵，则线性方程组$Ax=B$的Jacobi和Seidel迭代对任何初值$x^{(0)}$都收敛。
严格行对角占优矩阵$A=(a_{ij})_{n\times n}$：$|a_{kk}|>\sum\limits^n_{j=1,j\neq k}|a_{kj}|,\forall k$
严格列对角占优矩阵$A=(a_{ij})_{n\times n}$：$|a_{kk}|>\sum\limits^n_{i=1,i\neq k}|a_{ik}|,\forall k$
*定理：严格对角占优矩阵是非奇异的。*
**判别条件3** 若$A$是正定矩阵，则$Ax=B$的Seidel迭代对任何初值$x^{(0)}$都收敛。
正定矩阵：$A$的$k$阶主子式$|.|_k>0,k=1,\cdots,n$
#### 3.2.7 收敛误差估计
**定理4** 设矩阵$B$的某种矩阵范数$||B||<1$，则有：
1、$||x^{(k)}-x^*||\le\dfrac{||B||}{1-||B||}||x^{(k)}-x^{(k-1)}||$
2、$||x^{(k)}-x^*||\le\dfrac{||B||^k}{1-||B||}||x^{(1)}-x^{(0)}||$

### 3.3 线性方程组的直接解法
*有Gauss消元法（基础）、LU分解法等。*
三角方程组可以回代求解，一般方程组可用消元的方式华为三角方程组求解。
**基本思想** 先将线性方程组通过**消元方法**化为同解的上三角方程组，然后从该三角方程组中按第n个方程、n-1个方程、……**逐步回代**求出解。
#### 3.3.1 Gauss 消元法
1、Gauss消元法公式构造
记原方程组为：$\left\{\begin{array}{c}
a_{11}^{(0)}x_1+a_{12}^{(0)}x_2+\cdots+a_{1n}^{(0)}x_n=b_1^{(0)} \\
a_{21}^{(0)} x_1+a_{22}^{(0)} x_2+\cdots+a_{2n}^{(0)}x_n=b_2^{(0)}\\
\vdots \\
a_{n1}^{(0)}x_1+a_{n2}^{(0)}x_2+\cdots+a_{nn}^{(0)}x_n=b_n^{(0)}
\end{array}
\right.$
（1）消元
顺序做了n-1次消元后，变为上三角方程组：
$\left\{\begin{array}{} a_{11}^{(0)}x_1+a_{12}^{(0)}x_2+\cdots+a_{1n}^{(0)}x_n=b_1^{(0)} \\
a_{22}^{(1)} x_2+\cdots+a_{2n}^{(1)}x_n=b_2^{(1)}\\
\vdots \\
a_{nn}^{(n-1)}x_n=b_n^{(n-1)}
\end{array}
\right.$
（2）Gauss消元公式 略
#### 3.3.2 Gauss 消元法分析
1、Gauss消元法计算量
| 消元步 | 1 | 2 | … | n-1 |
| :------: | :------: | :----------: | :--: | :--: |
| 乘法次数 | $(n-1)n$ | $(n-1)(n-2)$ | … | 1×2 |
| 除法次数 | $n-1$ | $n-2$ | … | 1 |
$N_{消}=\sum\limits^{n-1}_{k=1}k(k+1)+\sum\limits^{n-1}_{k=1}k=\dfrac{n}{3}(n^2-1)+\dfrac{1}{2}n(n-1)$，$N_{回}=\dfrac{1}{2}n(n+1)$
计算量：$N=\dfrac{n^3}{3}+n^2-\dfrac{n}{3}\approx\dfrac{n^3}{3}$.
2、Gauss消元法矩阵解释
是对$(A,b)$做初等行变换，每次对一个方程做一次消元时，对应的初等矩阵为：
$M_{ik}=\left[\begin{array}{ccccccc} 1\\&\ddots\\&&1\\&&\vdots&\ddots\\&&m_{ik}&\cdots&1\\&&&&&\ddots\\&&&&&&1\end{array}\right]$
3、Gauss消元法可使用的条件
**定理1** $a_{kk}^{(k-1)}\neq 0,\forall k\Leftrightarrow$矩阵$A$的所有顺序主子式$\neq 0$
**定理2** 矩阵$A$的所有顺序主子式$\neq 0$，则Gauss消元法可使用
4、Gauss消元法缺点
**缺点1** 要求$a_{kk}^{(k-1)}\neq 0(k=1,2,\cdots,n)$
**缺点2** 在使用Gauss消元法进行计算机求解时，有时求出的解是错的。
#### 3.3.3 主元消元法
*列主元消元法、全主元消元法*
比较：
Gauss消元法：计算时间**最短**，精度**最差**；
全主元法：计算时间**最长**，精度**最高**；
实践表明：列主元法具有良好的数值稳定，且计算量远低于全主元法。
#### 3.3.4 LU 分解法
1、常用的矩阵三角分解
LU分解也成为了矩阵三角分解。常用的分解有三种：
1）Doolittle分解
$A=LU\quad L=\left[\begin{array}{ccc} 1\\l_{21}&1\\\vdots&&\ddots\\l_{n1}&l_{n2}&\cdots&1\end{array}\right],U=\left[\begin{array}{ccc} u_{11}&u_{12}&\cdots&u_{1n}\\&u_{22}&\cdots&u_{2n}\\&&\ddots&\vdots\\&&&u_{nn}\end{array}\right]$
2）Grout分解 略
3）LDU分解 略
$A=LDU$
2、基本思想
把一般线性方程组求解问题化为几个三角方程组来解。
$Ax=b\leftrightarrow LUx=b$
$Ax=b\leftrightarrow LDUx=b$
3、Doolittle分解法公式构造 略
4、Dlittle分解算法
1）$u_{ij}=a_{ij}-\sum\limits^{i-1}_{k=1}l_{ik}u_{kj},i\le j\quad l_{ij}=(a_{ij}-\sum\limits^{j-1}_{k=1}l_{ik}u_{kj})/u_{jj},i>j$，计算出$L$、$U$矩阵
2）回代求解$Ly=b$，解得$y^*$
3）回代求解$Ux=y^*$，得$Ax=b$的解$x$
5、$A$可以进行Doolittle分解的条件
**定理1** 非奇异矩阵$A$的Doolittle分解是唯一的。
**定理2** 若$A$ 各阶顺序主子式不为0，则$A$有唯一的Doolittle分解。
*能进行Gauss消元法就能做Doolittle分解。*
6、Doolittle分解的紧凑格式 略
#### 3.3.5 追赶法
是求三对角线性方程组专用的方法。
1、三对角方程组：$\begin{pmatrix}
b_1x_1 & c_1x_2& \cdots & \cdots&\cdots \\
\vdots & \ddots & \vdots &\cdots&\cdots\\
\cdots & a_ix_{i-1}& b_ix_{i} & b_{i+1}x_{i+1}&\cdots \\
\vdots & \vdots & \vdots& \ddots& \cdots \\
\cdots & \cdots & \cdots& a_{n}x_{n-1} & b_nx_n
\end{pmatrix} =\begin{pmatrix}
d_1 \\
\vdots \\
d_i \\
\vdots \\
d_n
\end{pmatrix}
(i=2,3\cdots n-1)$
2、追赶法公式推导
3、追赶法求解公式
$q_1=b_1,y_1=d_1$
$\left\{\begin{array}{l}p_k=a_k/q_{k-1}\\
q_k=b_k-p_kc_{k-1}\quad(k=2,3,\cdots,n)\\
y_k=d_k-p_ky_{k-1}\end{array}
\right.$
$x_n=y_n/q_n$
$x_k=(y_k-c_kx_{k+1})/q_k\quad (k=n-1,\cdots,1)$
用追赶法来求解三对角线性方程组，计算量只有$5n-4$。
#### 3.3.6 特殊解法
特殊线性方程组：指系数矩阵有很多0元素或有特殊结构的方程组。
用LU分解法解该类方程组会产生较多无效的零元计算，损失计算效率。因此应构造能去掉其中**无效、重复计算部分**的内容的专用算法。
### 3.4 线性方程组解对系数的敏感性
概念描述：指由于**系数的变化**（扰动），导致所求**解的变化**情况。
#### 3.4.1 系数敏感分析
设方程组$Ax=b$的解为$x^*$，系数扰动后对应的线性方程组为
$(A+\delta A)x=b+\delta b$
又设扰动方程组的准确解为$x^*+\delta x$有
$Ax^*=b;\quad (A+\delta A)(x^*+\delta x)=b+\delta b$
系数敏感对解的相对误差用$\dfrac{||\delta x||}{||x^*||}$的大小来描述。
1）考虑$\delta A=0$，即$Ax=b+\delta b$
有$Ax^*=b,A(x^*+\delta x)=b+\delta b$
（过程略）
$\dfrac{||\delta x||}{||x^*||}\le||A||\cdot||A^{-1}||\cdot\dfrac{||\delta b||}{||b||}$
2）考虑$\delta b=0$，即$(A+\delta A)=b$
可得：$\dfrac{||\delta x||}{||x^*||}\le\dfrac{||A||\cdot||A^{-1}||\cdot\dfrac{||\delta A||}{||A||}}{1-||A||\cdot||A^{-1}||\cdot\dfrac{||\delta A||}{||A||}}$
3）一般情况$(A+\delta A)x=b+\delta b$
可得：$\dfrac{||\delta x||}{||x^*||}\le\dfrac{||A||\cdot||A^{-1}||}{1-||A||\cdot||A^{-1}||\cdot\dfrac{||\delta A||}{||A||}}\left(\dfrac{||\delta A||}{||A||}+\dfrac{||\delta b||}{||b||}\right)$
矩阵$A$的条件数：$Cond_p(A)=||A||_p\cdot||A^{-1}||_p,p=1,2,\infty$
注：
- $Cond_p(A)$的值与矩阵范数有关，但相对大小一致。
- 条件数值越大，解对系数越敏感，方程组越病态。
条件数性质：
1、$A$可逆$\Rightarrow Cond_p(A)\ge 1$
2、$A$可逆$\Rightarrow Cond_p(\alpha A)=Cond_p(A),\forall \alpha\in R,\alpha\neq 0$
3、$A$正交$\Rightarrow Cond_2(A)=1$
病态矩阵特点：
1、行列式某些行、列近似相关；
2、元素间相差大数量级，且无规则；
3、主元消去过程中出现小主元；
4、特征值相差大数量级。
设$\overline{x}$是线性方程组$Ax=b$的近似解，称$r=A\overline{x}-b$为方程的**残向量**（或残量）
当矩阵$A$非病态时，残量可刻画近似解的准确程度。
$\dfrac{||\overline{x}-x^*||}{||x^*||}\le Cond(A)\dfrac{||r||}{||b||}$

where k can be of any size. At least one horizontal or vertical cell separates between two battleships (i.e., there are no adjacent battleships).
Example 1:
Input: board = [["X",".",".","X"],[".",".",".","X"],[".",".",".","X"]]
Output: 2
Example 2:
Input: board = [["."]]
Output: 0
Constraints:
m == board.length
n == board[i].length
1 <= m, n <= 200
board[i][j] is either '.' or 'X'.
*/
Cpp code :
class Solution {
public:
int countBattleships(vector<vector<char>>& board) {
int n = board.size();
int m = board[0].size();
int res = 0;
for(int i=0;i<n;i++)
{
for(int j=0;j<m;j++)
{
if((i == 0 || board[i-1][j] != 'X') && (j == 0 || board[i][j-1] != 'X') && board[i][j] == 'X')
res++;
}
}
return res;

title: 不删除关联关系表引起的一点思考
date: 2018-03-19 22:13:12
categories:
- MySQL
tags:

---
三张表，其中一张c是另外两张a,b的关系表。如果仅仅考虑删除的情况，那么只要删除a就行了。不用去碰c表（coding的时候最好别这样做）。
a表相当于指向c表的指针，指针没有了，所指向的内容也就没有了价值。
#### 下面是几个小例子：
1. Windows上无论删除哪里的内容，只是删除了指针。内容还在那里，不增不减。所以，才有恢复数据一说。
2. 在同一个磁盘里剪切是很快的，只是复制了指针。原数据还在那里不动的。不同磁盘间的复制很慢，那是真的在复制东西。所以Linux上 `mv`命令很快。
写不下去了，操作系统知识了解的太少。

## Setup
Set the following IDs on their relevant elements in the HTML:
```
"cd-weeks" - for weeks, no maximum value
"cd-days" - for days, up to 6 if weeks is defined
"cd-hours" - for hours, up to 23 if days is defined
"cd-minutes" - for minutes, up to 59 if hours is defined
"cd-seconds" - for seconds, up to 59 if minutes is defined
```
Add all IDs up to the last one you need (if you don't need all of the values).
## How to run
Run `new Countdown(dateToCountTo)` after the document is ready. `dateToCountTo` should be a valid date. Example "10/14/2017 12:36 PM".
## On End
Listen for `cdOver` window event - triggered when the countdown is over (and do something).
----
Use countdown.html for reference.

- Este es un proyecto realizado con laravel version 8.23.1 y vueJs.
## Intalación en linux
- Paso 1) Clonar el proyecto
- Paso 2) Ubicarlo el la carpeta raiz de su servidor web Ej: /var/www/html/ruleta
- Paso 3) Ejecutar composer install
- Paso 4) Crear el archivo .env
4.1) Ejecutar touch .env para crear el archivo .env
4.2) Ejecutar cp .env.example .env
- Paso 5) Configurar la base de datos mysql
5.1) En mi caso
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=ruleta
DB_USERNAME=laravel1
DB_PASSWORD=laravel
Dicha configuracion depende se su servidor mysql y el usuario.
* La base esta nombrada como ruleta.sql
- Paso 4) Ejecutar php artisan key:generate, laravel necesita una llave unica en nuestro proyecto
### Todos los pasos del 3 al 5 son explicados de una mejor forma en el siguiente post
https://parzibyte.me/blog/2017/05/29/hacer-despues-clonar-proyecto-laravel/
-paso 5) Ejecuar servidor interno de laravel para ver nuestro projecto
- php artisan serve

# Deep Detect Drawing
Deep detect Drawing is a app based on a CNN model, to recognize a few draw.
You can check the model construction [here](https://github.com/leersmathieu/deep-detect-drawing/blob/master/modeling%20notebook/object_recognition_model.ipynb)
# Training & accuracy
# Try it yourself !
On my serveur http://deepdrawing.tamikara.xyz/
OR
With *docker*
For try this app on your computer with docker, just enter this command in your terminal.
It's magic.
```docker
docker run -p 8501:8501 leersma/deep-detect-drawing:latest
```
just pay attention to the port used
If you run it on port 8501 as in the example, you can easily access it like this: http://localhost:8501/.

This app I built calls the studio ghibli API and lists every movie, person, location, and vehicle! you can even add your favorite movie to your profile for quicker access
MVP goals
I made four models
You can favorite a movie to profile
You can delete a movie from profile
Each item (movie, person, etc.) has a unique page when clicked on from the show page.
Stretch goals
Wanted movie poster pictures to show on the "show" page
Organize profile page with categories
Be able to add/delete any of the model pages to/from profile
Use a 2nd API for movie posters
Routes
Method Path Purpose
GET / home page that lists all pages and an intro
GET /profile gets profile page
POST /profile deletes from profile
GET /films lists all the films
POST /films send the film to profile
GET /people lists all the people
GET /locations lists all the locations
GET /vehicles lists all the vehicles
GET /auth/login shows login page
POST /auth/login posts info and logs in
GET /auth/register show register page
POST /auth/register posts register info to user and logs in
Models

[Video](https://youtu.be/FjEJ2LLkxHk)
### Objectives
- Understand WHY we want to use a Rails API
- Understand how to get a Rails API up and running from scratch
- Understand how to use a Rails API with your SPA
### Why a Rails API?
- JSON is language agnostic. It is just a string that follows rules that our language of choice can parse into a datatype that pertains to that language (e.g. Ruby Hashes, JavaScript Objets). We can then take that information and turn them into custom objects.
- So, we can now build a backend that can be used by MULTIPLE frontends! We can build a web app with JavaScript, a mobile app with Swift, Java, or React Native, and we can even let other developers use our backend to make their own sites!!!
- We can get the great user expereience of a JS-based frontend while keeping our backend flexible.
Do this with an existing rails app:
```ruby
class UsersController < ApplicationController
def index
@users = User.all
respond_to do |format|
format.html { render :index }
format.json { render json: @users }
end
end
end
```
If we navigate to http://localhost:3000/users.html we’ll see html, if we navigate to http://localhost:3000/users.json we will see JSON.
### Rails API - How?
We ONLY care about JSON now and will never want to return HTML
Start by doing:
`rails new my-app --api`
How is this different??
- No layout view
- Controller inherits from ActionController::API which is a lighter-weight version of the class. It does not have ActionView
Now, let's generate a user:
`rails g model user username password_digest name`
Migrate
`rails db:migrate`
And test it in the console
`User.create(name: "Micah", username: "micahshute")`
Note we will leave password blank for now.
Now, make the controller:
`rails g controller api/v1/users`
- Why do we version?
- It allows you to change the api which may break the code of people using v1, giving them time to transition over.
- How do we customize the JSON that is returned?
- Show relationshiops
- Hide data
### Serialization
Go into rails console:
```ruby
u = User.all.first
u.to_json
```
- Let's see how to include relationships and hide other data.
- Start by creating Tweet model which include content
`rails g model tweet content user:belongs_to`
Update models with has_many and belongs_to
Make some tweets in the console.
***Refresher Q: How do I make tweets in rails c?***
A:
```ruby
u = User.all.first
u.tweets.build(content: "My tweet!")
u.save
```
In the `users_controller.rb` file:
```ruby
def index
@users = User.all
render json: @users
end
```
See it in the browser. Now let's add the relationship and hide the password
Go to the route, let them figure out why the error is there. (No route)
***Q: How do I set up my routes?***
A:
```ruby
# config/routes.rb
Rails.application.routes.draw do
namespace :api do
namespace :v1 do
resources :users, only: [:index]
end
end
end
```
***Q: What route do I go to?***
A: /api/v1/users
and I get:
```json
[
{
id: 1,
username: "micahshute",
password_digest: null,
name: "Micah",
created_at: "2019-11-12T19:45:39.873Z",
updated_at: "2019-11-12T19:45:39.873Z"
}
]
```
OK, I want to get related tweets and not show my password_digest:
```ruby
#users_controller.rb
def index
@users = User.all
render json: @users, only: [:id, :name], include: :tweets
end
```
And now your password is hidden and you have your tweets coming through!
### Connect to the Front End
Go to any website (besides localhost) and attempt a fetch request (expecting CORS error)
```js
const url = 'http://localhost:3000/api/v1/users'
fetch(url)
.then(res => res.json())
.then(json => console.log(json))
```
ERROR:
```
Access to fetch at 'http://localhost:3000/api/v1/users' from origin 'https://education.flatironschool.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
Cross-Origin Read Blocking (CORB) blocked cross-origin response http://localhost:3000/api/v1/users with MIME type application/json. See https://www.chromestatus.com/feature/5629709824032768 for more details.
```
***Q: What does this mean??***
A: CORS has blocked us from making cross-site requests. It is important because it lets a website "whitelist" who is able to access it with fetch.
CORS Resources:
https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS
https://www.owasp.org/index.php/CORS_OriginHeaderScrutiny
CORS is a rule that `fetch` follows that prevents making a request from one website to another website unless the target website allows it explicitly.
So, let's tell our rails app to allow our frontend to get data from it!
we will start by just letting our API accept all traffic. You can later update this to ONLY allow your front-end (and your mobile app!)
### Allow CORS
1. Uncomment out `rack-cors` in Gemfile
2. run `bundle install`
3. Open `app/config/initializers/cors.rb` and change it to:
```ruby
Rails.application.config.middleware.insert_before 0, Rack::Cors do
allow do
origins '*'
resource '*',
headers: :any,
methods: [:get, :post, :put, :patch, :delete, :options, :head]
end
end
```
(should just be able to uncomment it)

Y ShapedLinked List
Above diagram shows an example with two linked list having 15 as intersection point.
Expected time complexity is O(m + n) where m and n are lengths of two linked lists
Input:
You have to complete the method which takes two arguments as heads of two linked lists.
Output:
The function should return data value of a node where two linked lists merge. If linked list do not merge at any point, then it shoudl return -1.
Constraints:
1 <=T<= 50
1 <=N<= 100
1 <=value<= 1000
Example:
Input:

2 3 2
10 20
30 40 50
5 10
2 3 0
10 20

First line is number of test cases. Every test case has four lines. First line of every test case contains three numbers, x (number of nodes before merge point in 1st list), y(number of nodes before merge point in 11nd list) and z (number of nodes after merge point). Next three lines contain x, y and z values.

[T3](http://t3js.org/) is a client-side JavaScript framework for building large-scale web applications. T3 is different than most JavaScript frameworks. It’s meant to be a small piece of an overall architecture that allows you to build scalable client-side code. A T3 application is managed by the Application object, whose primary job is to manage modules, services, and behaviors. It’s the combination of these three types of objects that allow you to build a scalable JavaScript front-end.
[T3](http://t3js.org/)’s design enforces best practices such as loose coupling by limiting how certain components can communicate with each other. Modules cannot interact directly with other modules but may communicate with them through an event bus. Modules may use services directly, but may only reference behaviors in a declarative way. These restrictions ensure that the various pieces remain loosely-coupled to make dependency management easy and maintenance self-contained.
The loosely-coupled nature of [T3](http://t3js.org/) components means that creating tests is easy. Dependencies are injected into each component, making it trivial to substitute a mock object in place of real ones. |

The script shows how to train Augmented SBERT (Domain-Transfer/Cross-Domain) strategy for STSb-QQP dataset.
For our example below we consider STSb (source) and QQP (target) datasets respectively.
Methodology:
Three steps are followed for AugSBERT data-augmentation strategy with Domain Trasfer / Cross-Domain -
1. Cross-Encoder aka BERT is trained over STSb (source) dataset.
2. Cross-Encoder is used to label QQP training (target) dataset (Assume no labels/no annotations are provided).
3. Bi-encoder aka SBERT is trained over the labeled QQP (target) dataset.
