title: "E80: Experimental Engineering"
---
## Welcome!
E80, Experimental Engineering, is a sophomore-level, semester-long required course, in which students conduct multiple experiments covering a number of engineering disciplines.
These experiments are a training ground for a final project: a field deployment where student teams measure phenomena of their choice.
Experimental Engineering is an essential part of the engineering curriculum at Harvey Mudd College, and has been offered as a course for over twenty years.
Its predecessor E54 - which had more experiments and no field experience - was also offered for more than 20 years.
The primary purpose of the course is to teach basic instrumentation and measurement techniques, good lab report practice, technical report writing, analysis and presentation of data, the usage of experimental results for engineering design purposes, and the beginnings of professional practice.
In 2008 the course was revamped to change the field experience to flying fully-instrumented model rockets. In 2017 the course was revamped again with yet another new field experience: deploying fully autonomous underwater robots.

Students may only work in the E80 labs when a professor, staff or a proctor opens the lab. Any team may use the equipment in the labs during a lab section, but teams that are scheduled for the section have top priority for the equipment.
## Mask Policy
Masks will be required for all E80 activities until further notice.
## Digital Communication
- [https://github.com/HMC-E80/E80](https://github.com/HMC-E80/E80) This is our Github repository, which lets you use Git to acces E80 software. Git is a distributed version control system where you can copy source code and track changes to the code. [Lab 0](/labs/lab0) will walk you through the steps to configure Git on your computer.
- [https://discord.gg/Eu7gFZKgcj](https://discord.gg/Eu7gFZKgcj) This is an invite to our Discord server. All digital communication and asynchronous help requests will go through Discord, so default to messaging there instead of emailing us.
- [https://harveymuddcollege.instructure.com/courses/1097](https://harveymuddcollege.instructure.com/courses/1097) This is our Canvas site. We will use Canvas to collect your assignments, receive your quiz responses and record your grades.
- All other information for the course is distributed on this website.
## Course kit fee
- There is a $65 kit fee per student. This fee can be waived in cases of financial hardship. Course instructors will not know about waiver requests.
- Kit payment can be made [here](https://docs.google.com/forms/d/e/1FAIpQLSfLGyW_zk6jB89jHjIme0mkHV_LVAtXeJSDNIf7njMEDN1t1w/viewform).
- Kit waiver request can be made [here](https://docs.google.com/forms/d/e/1FAIpQLScM-5lYfwQAE_5v6WAz357C1cftwr4sNQRPj4dC_GaPD-ihvw/viewform).
## Team and Group Assignments
Almost all work in E80 is completed in teams. Some details about teams are below.
- Teams are assigned before your first laboratory meeting.
- These assignments will be made using whatever method your instructor desires, and the nominal team size is four members.
- Sometimes registration limits in a class will require teams of three or five members to be formed.
- These teams are designated using a 2 digit number where the first is your section number and the second is your team's number (e.g. section 1's team 1 is 11).
- You must report your team number on all assignments.
- For three of the labs (2, 3, and 4), you will need to split your team into 2 sub-teams.
- A different sub-team must be used for each of these Labs.
- Team assignments will be for the duration of the course.
- If you're having problems on your team, talk to a professor or staff member *early* so we can try to help.
Team assignments can be found on the [People tab on Cavnas](https://harveymuddcollege.instructure.com/courses/1097/users).

### Turn-In on Canvas
All assignments that you need to complete, including links to quizzes, can be found in the [Modules tab on Cavnas](https://harveymuddcollege.instructure.com/courses/1097/modules). You will always turn in assignments on Canvas or complete quizzes/surveys linked from Canvas.
### Specifications Grading
The grading in E80 for submission sheets and writing assignments is based on whether or not your deliverables meet two different levels of specifications: **effort** and **completion**.
The overall grade on an assignment is determined by how many of the sections meet either effort or completion.
Effort specs describe **good-faith effort** whereas completion specs describe **correctness**.
In most situations, completing all the effort specs is equivalent to a passing grade on the assignment.
The remaining sections of completion specs raise your grade from a passing grade to full credit.
If the initial version of a submitted assignment does not meet specs, it may be revised according to the stipulations of the course [resubmissions policy](#resubmission-policy).
### Graded Submissions Details
#### Lecture Quizzes
- There are seven video lecture sets that you are expected to watch. Each of these video sets has an associated online quiz. You must take each of these quizzes individually.
- You may not talk to other people in order to take the quiz, but they are open book, notes and internet. The one exception to the 'no people' rule is that you may speak with a professor to clarify ideas before you open the quiz associated with the lecture set.
#### Surveys and Team Check-Ins
- You will be called upon to complete surveys at the beginning, middle and end of the class, and each week, you will be asked to complete a team check-in (a quick peer evaluation) for the lab done that week. Completing each of the check-ins is worth 0.5% of your grade, and completing each of the longer surveys is worth 1% of your grade.
- There are a total of 6 weekly check-ins (from weeks 2 through 7) and they are due each Friday at 3:30 pm.
- These are individual assignments
#### Laboratory Submission Sheets
- There are a total of 8 labs in the class: Lab0 through Lab7. You must submit a submission sheet for each of the labs that contains data you collected during the lab. (Though note that in lab0 the Matlab on-ramp deliverable is the submission sheet.) This submission sheet will be evaluated for correctness: it's a way of assessing whether your experimental procedure was correct during the lab. Each submission sheet you provide will be worth 4% of your final grade.
- These are group assignments, so there will be only one submission per team. The Matlab onramp for lab 0 is an exception: it is an individual assignment.
#### Laboratory Writing Assignments
- You will be required to complete a writing assignment after labs 1-5. The purpose of the writing assignments is to train you in specific aspects of scientific writing: making figures, using tables, equations, etc. These assignments are completed entirely on Friday in the Writing and Reflection section. Each writing assignment will be worth 3% of your final grade, and you submit five assignments for a total of 15%.
- These are individual assignments. The team contract exercise in week 0 is an exception, there should be one team contract submission per team.
#### Technical Memorandum
- Each student will write an individual technical memorandum on material covered in Lab 6. See the [Lab 6](labs/lab6) page for more information.
- You must submit a tech memo to pass the class.
#### Final Presentation
- Each team will make a final presentation during Presentation Days, on Wednesday, May 1st, 2024. A detailed schedule will be posted ASAP. The presentation is 15-minutes long followed by a 10-minute Q&A session. The Final Presentation guidelines and rubric are found on the [Final Project Report and Presentation page](/labs/project/report).
#### Final Report
- A final technical report will be submitted by each team on the results of the final AUV deployments. The report will be graded for both technical content and proper use of [technical English](https://www.mit.edu/course/21/21.guide/). A rough draft of your final report is due at 11:59 PM on 4/26/24. The final draft is due at 11:59 PM on 5/1/2024. The Final Report guidelines are found on the Final Project page.
#### Participation
- The instructors will assign you a participation grade which is determined by their in-lab observations, your peer evaluations, and your regular progress through the project checkoffs.
## End-of-Semester Grades
Grades will be awarded on a standard grading scale (93.3% is an A, 90% A-, 86.6% is a B+, etc ...) based on your total individual score.
The professors reserve the right to award grades more leniently than this grading standard.
## Course Calendar
A Google Sheet with the key dates and assignments in E80 can be found [here](https://docs.google.com/spreadsheets/d/1qR7HhVNWtqK8va9gGP6NGhX_NoIblt1x9VRRuFam1ng/edit?usp=sharing).
You can also review the [Modules tab on Cavnas](https://harveymuddcollege.instructure.com/courses/1097/modules) for a week-by-week breakdown of what's due with links to refernece material and where to turn stuff in.
## Course Policies
### Attendance and Tardiness
Students sometimes have to miss E80 labs for an assortment of reasons. The instructors don't record attendance because we assume that groups will work to equitably account for absences or tardiness. For example, if your group has a member with a planned absence for a particular lab, then you and your teammates should discuss how to shift more prelab work to the person who will be absent. If you don't feel like everyone is pulling their fair share, talk to your group and talk to an instructor so we can help you navigate the situation.
### Late Work Policy
No late work is accepted. You will receive no points for work submitted after deadlines.
This is in keeping with good professional practice. Some assignments may allow for multiple attempts and resubmission, but the first attempt always needs to be submitted by the appropriate deadline.
### Incomplete Grade Policy
Incomplete grades will be granted only in rare circumstances and require the approval of the instructor.
### Pre- and Post-Lab Work Policy
The amount of time that you are free to work in lab is restricted. We enforce these restrictions for three main reasons:
(1) to simulate demands that can arise in real-world engineering,
(2) to help students internalize the learning goals of the class, and
(3) to help keep E80 to a smaller time footprint.
You are allowed to work in any way you would like on before a lab (pre-lab) as long as you do not touch any hardware.
You may NOT collect data (for your experiment), manipulate or test hardware, populate a protoboard, or use the laboratory equipment outside of your lab hours.
However, you may look at datasheets, write software, calculate expected results, prepare Excel sheets to do calculations in lab, ask how equipment works, run your preparations by professors, and pursue a variety of other activities.
You can spend as much or as little time desired on the pre-lab activities, but successful teams spend a lot of time and energy before the lab starts.
The post-lab period is for reflection, resubmission when it's allowed, and taking a break from E80.
You may NOT collect data, manipulate or test hardware, populate a protoboard, or use the laboratory equipment outside of lab.
However, you may freely reprocess any data that you have already collected during a lab section.
This includes, but is not limited to, writing MATLAB code for processing and visualizing your data.
When in doubt about whether an activity is acceptable outside of lab, ask.
### Resubmission Policy
Lab submission sheets and writing assignments in E80 are able to be resubmitted without penalty if they do not meet completion specs on the initial attempt.
To be clear, this means that resubmitted assignments are worth the same amount as initial submission and full credit can be earned even if the initial submission does not fully meet the specifications.
The resubmission policy is subject to the stipulations listed below:
1. You must submit **something** by the assignment deadline.
- Don't phone this in because there is limited time for resubmission.
2. After you receive feedback, you can revise your submissions until spring break.
- Most of specs can be done outside of lab with data.
- However, if you weren't able to get good data, there is one week before spring break where you can go back to collect more.
3. Resubmissions are checked off by an instructor during office hours.
4. For all submissions, you will need to self-assess **before** you submit. Every assignment you submit should be accompanied along with a checklist of specs that you believe the assignment meets or does not meet.
5. All resubmissions must be completed by spring break.
### Cooperation Between Teams
Cooperation between teams is limited.
The rules for each period of the week (pre-lab, during lab, post-lab and writing and reflection) are below.
In this section, the word group will refer to a full team of students during a normal week or a sub-team of students during weeks where teams are split into sub-teams.
1. Pre-lab: A group may discuss the lab with another group to make sure they are clear on concepts and understanding. Groups may not share code, writing, or documentation with other groups.
2. During Lab: Groups cannot work together, discuss concepts or understanding, share data, share code, or share writing. Groups may arrange to swap hardware to debug and test defective parts of an experiment or device, but they should strongly consider elevating their concerns to an instructor if part swaps are necessary or if parts are being destroyed.
3. Post-Lab: Groups may work with other groups in the same way as the prelab: they may discuss concepts and understanding (including talking about the scale of measured results from lab).
4. Writing and Reflection: Each student should be producing an individual work product and may not exchange code or writing with other students. Data may be shared among a group, but not between groups.
These work restrictions are relaxed during the final project (after spring break): Groups may work on their robot at any time and may discuss any aspect of their robots with one another (as if the prelab policy always applies).
### Sharing Rubrics
We will be returning/releasing graded lab report rubrics throughout the semester.
It is an HONOR CODE VIOLATION to share these rubrics with other teams or with students enrolled in future versions of E80.
### Access to Lab During the Final Project
- Students may work in the labs any time that it is open.
- Students may only work in the E80 lab when a professor, staff member or proctor opens the lab.
- Any team may use the equipment in the E80 and electronics labs during a lab section, but teams which are scheduled for a section have top priority for the equipment.
### Accessibility and Accommodations
Harvey Mudd College strives to make all learning experiences as accessible as possible. If you anticipate or experience academic barriers based on your disability (including mental health, chronic or temporary medical conditions). If you have any questions, please contact the Office of Accessible Education at [[email protected]](mailto:[email protected]).

Chapter 2: The Soul of Italy - Naples
Introduction to Campania
Campania, with its vibrant streets and bustling markets, is the soul of Italy's pasta tradition. The region is home to Naples, the birthplace of many iconic Italian dishes, including pizza and spaghetti alla puttanesca. Campania's culinary scene is characterized by its use of fresh seafood, ripe tomatoes, and aromatic herbs, all of which play a central role in its pasta dishes.
History of Pasta in Campania
Pasta has been a staple in Campania for centuries, with records dating back to the 12th century when the region was a hub for pasta production and trade. The introduction of tomatoes from the New World in the 16th century transformed the culinary landscape of Naples, leading to the creation of now-iconic dishes such as spaghetti al pomodoro.
Regional Pasta Specialties
1. Spaghetti alla Puttanesca: A bold, flavorful dish made with tomatoes, olives, capers, and anchovies.
2. Linguine al Frutti di Mare: Pasta served with a mix of seafood, embodying the region's coastal flavors.
3. Gnocchi alla Sorrentina: Potato gnocchi baked with tomato sauce and mozzarella, a comforting dish that showcases Campania's dairy products.
Recipes

Coding Question -> 95% classical question or similar level question
both in interview or coding test
5% ques can be tough -> Tree, heap, map -> where multiple concept are being asked
1. **Introduction to Trees**:
- A tree is a hierarchical data structure consisting of nodes connected by edges.
- It is a special type of graph with no cycles, which means there is only one path between any two nodes.
2. **Tree Terminology**:
- **Node**: A fundamental unit of a tree, which stores data and has zero or more child nodes.
- **Root**: The topmost node in a tree, from which all other nodes are descended.
- **Leaf**: A node with no children, i.e., a node at the end of a branch.
- **Parent**: A node that has one or more child nodes.
- **Child**: A node that is a direct descendant of another node.
- **Siblings**: Nodes that share the same parent.
- **Depth**: The level of a node in the tree, with the root node at depth 0.
- **Height**: The length of the longest path from a node to a leaf.
3. **Binary Trees**:
- A binary tree is a tree in which each node can have at most two children, often referred to as the left child and the right child.
- Special types of binary trees include binary search trees (BSTs) where the left child is smaller than the parent, and the right child is larger.

In this N-ary tree:
- Node 1 is the root.
- Node 2, 3, and 4 are children of Node 1.
- Node 2 has two children, Node 5 and Node 6.
- Node 4 has one child, Node 7.
This is just a basic representation of an N-ary tree, where each node can have a variable number of children. In practice, N-ary trees can have more complex structures with different numbers of children for each node.
4. **Tree Traversal**:
- Tree traversal is the process of visiting and processing all nodes in a tree.
- Common traversal algorithms:
- **In-order**: Visit left subtree, visit the current node, visit right subtree (used for BSTs to get sorted output).
- **Pre-order**: Visit the current node, visit left subtree, visit right subtree (used for creating a copy of the tree).
- **Post-order**: Visit left subtree, visit right subtree, visit the current node (used for deleting a tree).
5. **Binary Heap**:
- A binary heap is a binary tree with special properties, often used to implement priority queues.
- Min-heap: The value of each node is smaller than or equal to the values of its children.
- Max-heap: The value of each node is greater than or equal to the values of its children.
6. **Balanced Binary Trees**:
- Balanced trees, like AVL trees and Red-Black trees, ensure that the tree remains relatively balanced, resulting in efficient operations.
- AVL trees: Ensure the balance factor (height difference between left and right subtrees) of each node is at most 1.
- Red-Black trees: Ensure the tree remains approximately balanced and have specific rules for coloring nodes to maintain balance.
7. **Tree Applications**:
- Trees are used in various applications, such as:
- Hierarchical data representation (file systems, organization charts).
- Searching and sorting (binary search trees).
- Expression parsing and evaluation.
- Game trees (e.g., in chess AI).
- Network routing algorithms (e.g., OSPF).
8. **Tree Operations**:
- Insertion: Adding a new node to the tree while maintaining its properties.
- Deletion: Removing a node from the tree while maintaining its properties.
- Searching: Finding a specific node or element in the tree.
- Updating: Modifying the value of a node.
These are some fundamental concepts and notes on trees in data structures and algorithms. Trees play a crucial role in various applications, and understanding them is essential for solving many algorithmic problems.

<h1 id="codeql安装">Codeql安装</h1>
<h2 id="引擎安装">引擎安装</h2>
<p>去https://github.com/github/codeql-cli-binaries/releases 下载对应系统版本的codeql引擎，并且添加到环境变量当中，在cmd中输入codeql可以查看是否设置成功</p>
<h2 id="sdk安装">SDK安装</h2>
<pre><code class="language-git">git clone https://github.com/Semmle/ql
</code></pre>
<h2 id="vscode插件">VSCode插件</h2>
<figure data-type="image" tabindex="1"><img src="https://ch1e-img.oss-cn-beijing.aliyuncs.com/img/image-20221016204658168.png" alt="image-20221016204658168" loading="lazy"></figure>
<p>并且在设置当中设置好codeql可执行文件的路径即可</p>
<h1 id="codeql使用">Codeql使用</h1>
<p>使用<a href="https://www.freebuf.com/author/l4yn3l">l4yn3 </a>师傅的靶场 https://github.com/l4yn3/micro_service_seclab/</p>
<p>为了测试刚刚的环境是否可用，用这个靶场来进行测试,命令如下</p>
<pre><code>codeql database create ~/CodeQL/databases/micro-service-seclab-database --language="java" --command="mvn clean install --file pom.xml" --source-root=~/CodeQL/micro-service-seclab/
</code></pre>
<p>这里使用maven编译的时候会导致不成功，可以在pom.xml文件中加入如下代码</p>
<pre><code class="language-xml"> <plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.22.2</version>
<configuration>
<skipTests>true</skipTests>
</configuration>
</plugin>
</code></pre>
<p>先来看看上面的命令的意思，codeql database create就是创建一个数据库，--language就是语言为java，--command就是用这个命令去编译(python和php脚本不需要)，--source-root就是项目路径</p>
<p>输入命令以后成功即可在vscode中导入数据库，也就是create后面的那个目录</p>
<figure data-type="image" tabindex="2"><img src="https://ch1e-img.oss-cn-beijing.aliyuncs.com/img/image-20221016205121599.png" alt="image-20221016205121599" loading="lazy"></figure>
<p>然后使用vscode打开我们下载的sdk目录，在java/ql目录下可以新建个test.ql，输入<code>select "hello world"</code>即可测试，部分因为版本原因会报错，这时候需要先在 ql 文件同级目录下创建一个名为 <strong>qlpack.yml</strong>，内容如下：</p>
<pre><code>name: mssql
version: 0.0.1
libraryPathDependencies: codeql/java-all
</code></pre>
<p>然后右键Codeql:run Query即可运行ql文件</p>
<figure data-type="image" tabindex="3"><img src="https://ch1e-img.oss-cn-beijing.aliyuncs.com/img/image-20221016205409506.png" alt="image-20221016205409506" loading="lazy"></figure>
<h1 id="codeql语法">Codeql语法</h1>
<p>QL查询的语法结构为</p>
<pre><code>from [datatype] var
where condition(var = something)
select var
</code></pre>
<p>经常会用到的ql类库如下:</p>
<table>
<thead>
<tr>
<th style="text-align:center">名称</th>
<th style="text-align:center">解释</th>
</tr>
</thead>
<tbody>
<tr>
<td style="text-align:center">Method</td>
<td style="text-align:center">方法类，Method method表示获取当前项目中所有的方法</td>
</tr>
<tr>
<td style="text-align:center">MethodAccess</td>
<td style="text-align:center">方法调用类，MethodAccess call表示获取当前项目当中的所有方法调用</td>
</tr>
<tr>
<td style="text-align:center">Parameter</td>
<td style="text-align:center">参数类，Parameter表示获取当前项目当中所有的参数</td>
</tr>
</tbody>
</table>
<h2 id="method">Method</h2>
<p>获取项目中定义的所有方法:</p>
<pre><code>import java
from Method method
select method
</code></pre>
<figure data-type="image" tabindex="4"><img src="https://ch1e-img.oss-cn-beijing.aliyuncs.com/img/image-20221016210536254.png" alt="image-20221016210536254" loading="lazy"></figure>
<p>获取名为getStudent的方法名称</p>
<pre><code>import java
from Method method
where method.hasName("getStudent")
select method.getName(),method.getDeclaringType()
</code></pre>
<figure data-type="image" tabindex="5"><img src="https://ch1e-img.oss-cn-beijing.aliyuncs.com/img/image-20221016211112926.png" alt="image-20221016211112926" loading="lazy"></figure>
<pre><code>method.getName() 获取的是当前方法的名称
method.getDeclaringType() 获取的是当前方法所属class的名称。
</code></pre>
<h2 id="谓词">谓词</h2>
<p>类似于函数，其实就和函数差不多。对于上面的案例，可以修改一下</p>
<pre><code>import java
predicate isStudent(Method method){
exists(|method.hasName("getStudent"))
}
from Method method
where isStudent(method)
select method.getName(),method.getDeclaringType()
</code></pre>
<p>predicate表示当前方法没有返回值，exists子查询，根据内部子查询返回true或者false，来筛选出数据</p>
<h2 id="source和sink">Source和Sink</h2>
<blockquote>
<p>什么是source和sink</p>
<p>在代码自动化安全审计的理论当中，有一个最核心的三元组概念，就是(source，sink和sanitizer)。</p>
<p>source是指漏洞污染链条的输入点。比如获取http请求的参数部分，就是非常明显的Source。</p>
<p>sink是指漏洞污染链条的执行点，比如SQL注入漏洞，最终执行SQL语句的函数就是sink(这个函数可能叫query或者exeSql，或者其它)。</p>
<p>sanitizer又叫净化函数，是指在整个的漏洞链条当中，如果存在一个方法阻断了整个传递链，那么这个方法就叫sanitizer。</p>
<p><strong>只有当source和sink同时存在，并且从source到sink的链路是通的，才表示当前漏洞是存在的。</strong></p>
</blockquote>
<p>source通俗的说就是我们可控的变量，Sinkd通俗的说就是危险函数，这也就是代码审计的最基本的可控变量+危险函数。</p>
<h3 id="设置source">设置Source</h3>
<p>codeql中通过下面的代码来设置source</p>
<pre><code>override predicate isSource(DataFlow::Node src) {}
</code></pre>
<p>可以看看我们靶场系统中的source是什么，比如</p>
<pre><code class="language-java">@RequestMapping(value = "/one")
public List<Student> one(@RequestParam(value = "username") String username) {
return indexLogic.getStudent(username);
}
</code></pre>
<p>采用了springboot框架，懂的师傅都知道，我们需要对/one路由传入username参数，在这，username就是source</p>
<pre><code class="language-java">@PostMapping(value = "/object")
public List<Student> objectParam(@RequestBody Student user) {
return indexLogic.getStudent(user.getUsername());
}
</code></pre>
<p>在这source就是user，和类型无关，本例中我们设置Source的代码为：</p>
<pre><code>override predicate isSource(DataFlow::Node src) { src instanceof RemoteFlowSource }
</code></pre>
<p>这是<code>SDK</code>自带的规则，里面包含了大多常用的Source入口。我们使用的SpringBoot也包含在其中, 我们可以直接使用。</p>
<h3 id="设置sink">设置Sink</h3>
<p>在本案例中，我们的sink应该为<code>query</code>方法(Method)的调用(MethodAccess)，所以我们设置Sink为：</p>
<pre><code>override predicate isSink(DataFlow::Node sink) {
exists(Method method, MethodAccess call |
method.hasName("query")
and
call.getMethod() = method and
sink.asExpr() = call.getArgument(0)
)
}
</code></pre>
<p>上面查询的意思为：查找一个query()方法的调用点，并把它的第一个参数设置为sink。<br>
在靶场系统(<code>micro-service-seclab</code>)中，sink就是：</p>
<pre><code>jdbcTemplate.query(sql, ROW_MAPPER);
</code></pre>
<h2 id="flow数据流">Flow数据流</h2>
<blockquote>
<p>设置好 Source 和 Sink，就相当于搞定了首尾，但是首尾是否能够连通才能决定是否存在漏洞！</p>
<p>一个受污染的变量，能够毫无阻拦的流转到危险函数，就表示存在漏洞！</p>
</blockquote>
<p>我们通过使用<code>config.hasFlowPath(source, sink)</code>方法来判断是否连通。</p>
<pre><code>from VulConfig config, DataFlow::PathNode source, DataFlow::PathNode sink
where config.hasFlowPath(source, sink)
select source.getNode(), source, sink, "source"
</code></pre>
<h1 id="初步成果">初步成果</h1>
<p>我们使用官方提供的TaintTracking::Configuration方法定义source和sink，至于中间是否是通的，这个后面使用CodeQL提供的<code>config.hasFlowPath(source, sink)</code>来帮我们处理。</p>
<p>我们最终第一版写的demo.ql如下：</p>
<pre><code>/**
* @id java/examples/vuldemo
* @name Sql-Injection
* @description Sql-Injection
* @kind path-problem
* @problem.severity warning
*/
import java
import semmle.code.java.dataflow.FlowSources
import semmle.code.java.security.QueryInjection
import DataFlow::PathGraph
class VulConfig extends TaintTracking::Configuration {
VulConfig() { this = "SqlInjectionConfig" }
override predicate isSource(DataFlow::Node src) { src instanceof RemoteFlowSource }
override predicate isSink(DataFlow::Node sink) {
exists(Method method, MethodAccess call |
method.hasName("query")
and
call.getMethod() = method and
sink.asExpr() = call.getArgument(0)
)
}
}
from VulConfig config, DataFlow::PathNode source, DataFlow::PathNode sink
where config.hasFlowPath(source, sink)
select source.getNode(), source, sink, "source"
</code></pre>
<p>CodeQL语法和Java类似，extends代表集成父类TaintTracking::Configuration。</p>
<p>这个类是官方提供用来做数据流分析的通用类，提供很多数据流分析相关的方法，比如isSource(定义source)，isSink(定义sink)</p>
<p>src instanceof RemoteFlowSource 表示src 必须是 RemoteFlowSource类型。在RemoteFlowSource里，官方提供很非常全的source定义，我们本次用到的Springboot的Source就已经涵盖了。</p>
<h1 id="误报解决">误报解决</h1>
<p>在上面的初版代码中，会存在误报，这里的List泛型是Long，不可能注入的</p>
<figure data-type="image" tabindex="6"><img src="https://ch1e-img.oss-cn-beijing.aliyuncs.com/img/image-20221016222149948.png" alt="image-20221016222149948" loading="lazy"></figure>
<p>这说明我们的规则里，对于List<Long>，甚至List<Integer>类型都会产生误报，source误把这种类型的参数涵盖了。可以使用isSanitizer</p>
<blockquote>
<p>isSanitizer是CodeQL的类<code>TaintTracking::Configuration</code>提供的净化方法。它的函数原型是：</p>
<p>override predicate isSanitizer(DataFlow::Node node) {}</p>
<p>在CodeQL自带的默认规则里，对当前节点是否为基础类型做了判断。</p>
<p>override predicate isSanitizer(DataFlow::Node node) {<br>
node.getType() instanceof PrimitiveType or<br>
node.getType() instanceof BoxedType or<br>
node.getType() instanceof NumberType<br>
}</p>
<p>表示如果当前节点是上面提到的基础类型，那么此污染链将被净化阻断，漏洞将不存在。</p>
</blockquote>
<p>所以我们只要在基本的内容上加点特殊的处理即可。</p>
<pre><code>override predicate isSanitizer(DataFlow::Node node) {
node.getType() instanceof PrimitiveType or
node.getType() instanceof BoxedType or
node.getType() instanceof NumberType or
exists(ParameterizedType pt| node.getType() = pt and pt.getTypeArgument(0) instanceof NumberType )
}
</code></pre>
<p>如果当前node节点的类型为基础类型，数字类型和泛型数字类型(比如List)时，就切断数据流，认为数据流断掉了，不会继续往下检测。</p>
<h1 id="漏报解决">漏报解决</h1>
<p>有如下代码</p>
<pre><code class="language-java">public List<Student> getStudentWithOptional(Optional<String> username) {
String sqlWithOptional = "select * from students where username like '%" + username.get() + "%'";
//String sql = "select * from students where username like ?";
return jdbcTemplate.query(sqlWithOptional, ROW_MAPPER);
}
</code></pre>
<p>其中是通过username.get()获取的，应该是这里让他source-sink的链接断了，我们强制接上即可</p>
<figure data-type="image" tabindex="7"><img src="https://ch1e-img.oss-cn-beijing.aliyuncs.com/img/image-20221016222713604.png" alt="image-20221016222713604" loading="lazy"></figure>
<blockquote>
<p>isAdditionalTaintStep方法是CodeQL的类<code>TaintTracking::Configuration</code>提供的的方法，它的原型是：</p>
<p>override predicate isAdditionalTaintStep(DataFlow::Node node1, DataFlow::Node node2) {}</p>
<p>它的作用是将一个可控节点<br>
A强制传递给另外一个节点B，那么节点B也就成了可控节点。</p>

<p>我们都知道，我们可以使用exists(|)这种子查询的方式定义source和sink，但是如果source/sink特别复杂（比如我们为了规则通用，可能要适配springboot， Thrift RPC，Servlet等source），如果我们把这些都在一个子查询内完成，比如 condition 1 or conditon 2 or condition 3, 这样一直下去，我们可能后面都看不懂了，更别说可维护性了。<br>
况且有些情况如果一个子查询无法完成，那么就更没法写了。</p>
</blockquote>
<p>instanceof给我们提供了一种机制，我们只需要定义一个abstract class，比如这个案例当中的:</p>
<pre><code>/** A data flow source of remote user input. */
abstract class RemoteFlowSource extends DataFlow::Node {
/** Gets a string that describes the type of this remote flow source. */
abstract string getSourceType();
}
</code></pre>
<p>然后在isSource方法里进行instanceof，判断src是 RemoteFlowSource类型就可以了。</p>
<pre><code>override predicate isSource(DataFlow::Node src) {
src instanceof RemoteFlowSource
}
</code></pre>
<h1 id="lombok问题">Lombok问题</h1>
<p>Lombok会自动生成get和set方法，正常代码就是</p>
<pre><code class="language-java">package com.l4yn3.microserviceseclab.data;
import lombok.Data;
@Data
public class Student {
private int id;
private String username;
private int sex;
private int age;
}
</code></pre>
<p>但是由于lombok的实现机制，导致CodeQL无法获取到lombok自动生成的代码，所以就导致使用了lombok的代码即使存在漏洞，也无法被识别的问题。</p>
<p>还好CodeQL官方的issue里面，有人给出了这个问题的解决办法（[查看](https://github.com/github/codeql/issues/4984#:~:text=Unfortunately Lombok does not work with the CodeQL,the source files before running CodeQL as follows%3A)）。</p>
<pre><code># get a copy of lombok.jar
wget https://projectlombok.org/downloads/lombok.jar -O "lombok.jar"
# run "delombok" on the source files and write the generated files to a folder named "delombok"
java -jar "lombok.jar" delombok -n --onlyChanged . -d "delombok"
# remove "generated by" comments
find "delombok" -name '*.java' -exec sed '/Generated by delombok/d' -i '{}' ';'
# remove any left-over import statements
find "delombok" -name '*.java' -exec sed '/import lombok/d' -i '{}' ';'
# copy delombok'd files over the original ones
cp -r "delombok/." "./"
# remove the "delombok" folder
rm -rf "delombok"
</code></pre>
<p>上面的代码，实现的功能是：去掉代码里的lombok注解，并还原setter和getter方法的java代码，从而使CodeQL的Flow流能够顺利走下去，从而检索到安全漏洞。</p>

The '''pelvic cavity''' is a [[body cavity]] that is bounded by the bones of the [[pelvis]]. Its oblique roof is the [[pelvic inlet]] (the superior opening of the pelvis). Its lower boundary is the [[pelvic floor]].
The pelvic cavity primarily contains [[reproductive organs]], the [[urinary bladder]], the [[pelvic colon]], and the [[rectum]]. The [[rectum]] is placed at the back of the pelvis, in the curve of the [[sacrum]] and [[coccyx]]; the bladder is in front, behind the [[pubic symphysis]].
In the female, the [[uterus]] and [[vagina]] occupy the interval between these viscera. The pelvic cavity also contains major arteries, veins, muscles, and nerves. These structures have to work together in a little crowded space. They can be affected by many different diseases and by many drugs in many different ways. One part may impact upon another, for example constipation may overload the rectum and compress the urinary bladder, or childbirth might damage the [[Pudendal nerve|pudendal nerves]] and later lead to anal weakness.
==Borders==
[[File:Pelvis.jpg|thumb|right|300px|Pelvis]]
The pevis has an anteroinferior, a posterior and two lateral pelvic walls; and an inferior pelvic wall, also called the [[Pelvic floor]].<ref>Moore, Keith L. et al. (2010) ''Clinically Oriented Anatomy'' 6th Ed, ch.3 ''Pelvis and perineum'', p.339</ref><ref>Richard S. Snell ''Clinical Anatomy By Regions'', ''Pevic cavity'' [http://books.google.com/books?id=vb4AcUL4CE0C&pg=PA242 p.242]</ref> The [[parietal peritoneum]] is attached here and to the [[abdominal wall]].<ref>Tank, P. (2013) ''Grants Dissector'' 15th ed., ch.4 ''The abdomen'', p.99</ref>
=== Lesser pelvis ===
The lesser pelvis (or "true pelvis") is the space enclosed by the [[pelvic girdle]] and below the [[pelvic brim]]: between the [[pelvic inlet]] and the [[pelvic floor]]. This cavity is a short, curved canal, deeper on its posterior than on its anterior wall. Some consider this region to be the entirety of the pelvic cavity. Others define the pelvic cavity as the larger space including the [[#Greater pelvis|greater pelvis]], just above the pelvic inlet.
The lesser pelvis is bounded in front and below by the [[pubic symphysis]] and the [[superior rami of the pubes]]; above and behind, by the sacrum and coccyx; and laterally, by a broad, smooth, quadrangular area of bone, corresponding to the inner surfaces of the body and superior ramus of the [[ischium]], and the part of the [[ilium]] below the [[arcuate line (ilium)|arcuate line]].

The lesser pelvis contains the [[pelvic colon]], [[rectum]], [[Urinary bladder|bladder]], and some of the [[organs of generation]].
The [[rectum]] is at the back, in the curve of the [[sacrum]] and [[coccyx]]; the bladder is in front, behind the [[pubic symphysis]]. In the female, the [[uterus]] and [[vagina]] occupy the interval between these viscera.
The [[pelvic splanchnic nerves]] arising at S2-S4 are in the lesser pelvis.
=== Greater pelvis ===
The greater pelvis (or "false pelvis") is the space enclosed by the [[pelvic girdle]] above and in front of the [[pelvic brim]].
It is bounded on either side by the [[ilium (bone)|ilium]]; in front it is incomplete, presenting a wide interval between the anterior borders of the [[ilium (bone)|ilia]], which is filled by the [[parietes]] of the [[abdomen]]; behind is a deep notch on either side between the ilium and the [[base of the sacrum]].
It is generally considered part of the [[abdominal cavity]] (this is why it is sometimes called the false pelvis).<ref>Drake et al. (2009) Grays Anatomy for Students, 2nd Edition, ch.5 ''Pelvis and perineum - ''general description'', p.406</ref> Some{{who|date=April 2013}} consider this region part of the pelvic cavity,{{cn|date=April 2013}} while others reframe the classification question by calling the combination the [[abdominopelvic cavity]].
The greater pelvis supports the [[intestines]] (specifically, the [[ileum]] and [[sigmoid colon]]), and transmits part of their weight to the anterior wall of the [[abdomen]].
The [[femoral nerve]] from L2-L4 is in the greater pelvis, but not in the lesser pelvis.

title: "자바스크립트 변수의 값 검사 방법"
description: " "
date: 2023-09-09
tags: [javascript]
comments: true
share: true
---
자바스크립트에서 변수의 값 검사는 매우 중요합니다. 정확한 값 검사를 통해 프로그램의 안정성과 신뢰성을 확보할 수 있습니다. 이 글에서는 다양한 자바스크립트 변수의 값 검사 방법을 알아보겠습니다.
## 1. typeof 연산자를 사용한 값 검사
자바스크립트에서는 `typeof` 연산자를 사용하여 변수의 타입을 확인할 수 있습니다. 다음은 `typeof` 연산자를 사용하여 변수 `x`의 타입을 검사하는 예시입니다:
```javascript
var x = 10;
console.log(typeof x); // 출력: "number"
x = "Hello";
console.log(typeof x); // 출력: "string"
x = true;
console.log(typeof x); // 출력: "boolean"
```
`typeof` 연산자는 변수의 타입을 문자열로 반환합니다. 이를 통해 변수의 타입에 따라 다른 동작을 수행할 수 있습니다.
## 2. 값이 유효한지 확인하기
자바스크립트에서 값이 유효한지 확인하는 방법은 여러 가지가 있습니다. 가장 간단한 방법은 변수의 값이 `null` 또는 `undefined`인지 확인하는 것입니다. 다음은 변수 `x`의 값이 `null` 또는 `undefined`인지 확인하는 예시입니다:
```javascript
var x = null;
if (x === null || x === undefined) {
console.log("x is null or undefined");
} else {
console.log("x is not null or undefined");
}
```
또한 값을 확인하기 위해 논리 연산자를 사용할 수도 있습니다. 예를 들어, `x`가 `null` 또는 `undefined`이면 `y`에 기본 값을 할당하는 예시를 살펴보겠습니다:
```javascript
var x = null;
var y = x || "default value";
console.log(y); // 출력: "default value"
```
위 코드에서 `x`가 `null` 또는 `undefined`이므로 `y`에는 `"default value"`라는 기본 값이 할당됩니다.
## 3. 배열이 비어있는지 확인하기
배열이 비어있는지 확인하는 방법은 다양합니다. 가장 간단한 방법은 배열의 `length` 속성을 사용하여 길이를 확인하는 것입니다. 다음은 배열이 비어있는지 확인하는 예시입니다:
```javascript
var arr = [];
if (arr.length === 0) {
console.log("Array is empty");
} else {
console.log("Array is not empty");
}
```
또는 배열의 `isArray()` 메소드를 사용하여 배열인지 확인하고, 배열이 비어있는지 검사할 수도 있습니다:
```javascript
var arr = [];
if (Array.isArray(arr) && arr.length === 0) {
console.log("Array is empty");
} else {
console.log("Array is not empty");
}
```
위 코드에서 `Array.isArray(arr)`는 `arr`이 배열인지 확인하고, `arr.length === 0`은 배열이 비어있는지 확인합니다.
## 4. 객체가 비어있는지 확인하기
객체가 비어있는지 확인하는 방법도 여러 가지가 있습니다. 가장 간단한 방법은 객체의 속성 개수를 확인하는 것입니다. 다음은 객체가 비어있는지 확인하는 예시입니다:
```javascript
var obj = {};
if (Object.keys(obj).length === 0) {
console.log("Object is empty");
} else {
console.log("Object is not empty");
}
```
위 코드에서 `Object.keys(obj).length === 0`은 객체에 속성이 없는지 확인합니다.
## 5. 변수가 정의되었는지 확인하기
변수가 정의되었는지 확인하는 방법은 `typeof` 연산자를 사용하여 `undefined`인지 확인하는 것입니다. 다음은 변수가 정의되었는지 확인하는 예시입니다:
```javascript
var x;
if (typeof x === "undefined") {
console.log("x is not defined");
} else {
console.log("x is defined");
}
```
위 코드에서 `typeof x === "undefined"`은 변수 `x`가 정의되지 않았는지 확인합니다.
## 결론
자바스크립트에서 변수의 값 검사는 프로그램의 안정성과 신뢰성을 확보하기 위해 필수적입니다. `typeof` 연산자를 사용하여 변수의 타입을 확인하고, 값이 유효한지, 배열이 비어있는지, 객체가 비어있는지, 변수가 정의되었는지 확인하는 등 다양한 방법을 통해 변수의 값 검사를 수행할 수 있습니다. 올바른 값 검사를 통해 안정적인 자바스크립트 코드를 작성할 수 있습니다.

title: Schema management in Kafka
date: 2020-05-27
---
Kafka stores records as binary data. When stored on the broker, it is simply a stream of bytes. There needs to be a contract between publishers and subscribers to know how to encode/decode a message in a topic. The encoding/decoding is also known as serialization/deserialization.
For Kafka, a widely adopted serialization format is Avro. All messages stored within a topic should be encoded with same or similar schemas to avoid compatibility issues.
## Serialization/Deserialization
How to encode and publish a message (Publisher side)
1. Get the avro schema
2. Create an encoder for that schema
3. Encode the message using schema
4. Push the encoded bytes to the broker
How to consume the message (Consumer side)
1. Get the avro schema
2. Create a decoder for the schema
3. Read the bytes from the broker
4. Use the decoder to recover back the message
There are Avro libraries/SDK available in all major languages. Avro schema is a standard format represented as a JSON. You can read more about Avro [here](https://avro.apache.org/).
If you follow the steps above, there are 2 major aspects of reading and writing from Kafka. One is creating the encoder/decoder which is made easier thanks to Avro libraries available to us. The other aspect is the contract between publishers and consumers of a topic to make sure they both have a consistent schema to refer to when reading/writing those messages. If A publishes messages using schema 1 and B tries to decode it using schema 2, it can be interpreted in a very different way which defeats the purpose of sharing the information.
Once the 2 parties (or multiple) decide on the schema or format, they can store that schema locally in their application and read/write from Kafka asynchronously. However, when the publisher wishes to alter the schema by adding/deleting a field or type conversions, they have to relay that information to everyone who is associated with that topic. This is where schema management becomes important. A common store to share and store schemas would make life much easier.
## Schema Registry
Confluent introduced a schema store they called Schema Registry. It is a distributed metadata store that provides a RESTful interface to store and retrieve schemas. It supports Avro, JSON, Protobuf schemas that can be shared among all consumers and publishers. It is provided as a separate service and can be deployed with or without Kafka platform.
### Registering a schema
A JSON based schema can be registered as a HTTP POST request. Every schema is assigned a unique **schema ID** that can serve as an identifier for a schema. If you try to register the same schema again, it will simply return the same schema ID of the original one. The schema IDs are monotonically increasing as you add more schemas.
In a Kafka topic, the key and the value can both have different schemas. Schema registry supports topic schemas based on the topic name and whether it is a key or a value. The combination of topic and key/value identifier is what is called _subject_. Schemas can evolve in a compatible way to support multiple formats for a topic.
### Fetching a schema
A schema is identified either by the subject or schemaID. A simple GET request with a subject or a schema ID parameter will return a JSON based format that can be saved and used by the decoder.
### Embedding schema ID in Kafka messages
A common pratice followed across the industry is embedding schemaID to every Kafka message. The first byte is a 0x0 character followed by 4 bytes representing the schemaID and the rest of the message is the encoded bytes.
Kafka message with schema ID 35 would look like below:
`00 00 00 00 23 21 22 .....`
The first byte is the null byte, the next 4 bytes are 0x23 (35) followed by encoded bytes.
This approach doesnt add more than 4 bytes of overhead to your message and can get the schema using the schema ID for every message independently. The schema fetched can be cached to avoid fetching schema on every message and only fetched when it has evolved in the middle.

# Diabetic Management Mobile App
Welcome to the Diabetic Management Mobile App project! This mobile app is designed to help individuals with diabetes manage their condition more effectively. The app provides users with tools and features to monitor their blood sugar levels, track medication intake, record food consumption, and receive valuable insights to better manage their health.
## Features
The Diabetic Management Mobile App comes with the following features:
1. **Blood Sugar Tracking**: Users can record their blood sugar levels at different times of the day and track the trends over time.
2. **Medication Reminders**: The app allows users to set reminders for taking their medications, ensuring they never miss a dose.
3. **Food Journal**: Users can keep a record of their meals and snacks, including carbohydrate counts and mealtime notes.
4. **Activity Monitoring (Optional)**: In future iterations, we plan to add activity tracking to help users monitor their physical activity levels.
5. **Insights and Analytics (Future Development)**: The app aims to provide users with valuable insights and analytics based on their data to identify patterns and make informed decisions.
## Frontend
The frontend of the mobile app has been developed using Flutter, a powerful and flexible framework for building native mobile applications for Android and iOS platforms. The user interface (UI) and user experience (UX) have been designed to be intuitive and user-friendly, with a focus on delivering a smooth and responsive experience.
## Backend (Work in Progress)
The next phase of development involves building the backend for the app. We plan to use Node.js with Express to create a robust and scalable backend that will handle user authentication, data storage, and provide APIs for the frontend to interact with the server.
## Project Setup
To set up the app on your local machine, follow these steps:
1. Clone the repository from GitHub: [project-repository-url](https://github.com/octorose/D-one2.git).
2. Install the required dependencies by following the instructions provided in the `README` file of the project.
3. Run the app on your preferred mobile device simulator or physical device.
## Contribution Guidelines
We welcome contributions to this open-source project. If you want to contribute, follow these guidelines:
1. Fork the project repository to your GitHub account.
2. Create a new branch from the `main` branch for each feature or bug fix.
3. Make your changes and additions, ensuring that the code is well-documented and follows best practices.
4. Test your changes locally to avoid any potential issues.
5. Once you are confident with your changes, create a pull request to merge your branch into the `main` branch.
6. Discuss your changes with the maintainers and incorporate feedback to improve the project.
7. Be respectful and collaborative in the development process.
## Future Roadmap
As this project progresses, we have some exciting features planned for future development:
- Integration with Continuous Glucose Monitoring (CGM) devices to enable real-time data tracking.
- Enhanced data visualization to help users better understand their health trends.
- Integration with health professionals to provide personalized recommendations and support.
- Multi-language support to make the app accessible to a wider user base.
Thank you for your interest in the Diabetic Management Mobile App project. Together, we can make a positive impact on the lives of individuals managing diabetes. Happy coding!
