Ever been in a conversation where you felt like your brain was melting? You know the kind. You’re making a point — calmly, rationally, maybe even with a dash of charm — and suddenly you’re drowning in a tidal wave of nonsense. Personal attacks. Wild conclusions. The type of logic that makes you wonder if the other person recently suffered a head injury. It’s infuriating. It makes you want to flip a table and scream: ‍ ‍ But here’s the thing: Sometimes you can’t avoid these people. Maybe it’s your boss. Maybe it’s a relative you only see at holidays. Maybe it’s the guy in line at the grocery store who thinks he’s the second coming of Aristotle because he read one headline on Facebook. For these moments, you need tools. Not to “win” the argument — because half the time, winning just means wasting more energy — but to keep your sanity and not lose faith in the species. Here are 8 of the sneakiest logic traps people use and how to dismantle them without losing your mind (or your soul). ‍ 1. Ad Hominem The Classic Cheap Shot. Instead of debating your point, they debate you. Because why confront a real argument when they can take a swing at your character? Example: You: “I think this company should adopt more sustainable practices. ”Them: “Oh, coming from the guy who still drives a gas guzzler?” Counter: “Me driving a gas guzzler doesn’t change the fact that sustainability is important. Maybe let’s focus on the idea instead of my car.” Translation: Stop making this about me. My hypocrisy (real or imagined) doesn’t make your argument better. ‍ 2. Straw Man Building a Scarecrow, Then Setting It on Fire. This is when someone takes what you said, twists it into a ridiculous caricature, and then torches that nonsense instead of your actual point. Example: You: “I think remote work has its benefits. ”Them: “So you just want everyone to sit at home in pajamas and never talk to another human again?” Counter: “I didn’t say that. Remote work doesn’t mean social isolation. It means flexibility. Two very different things.” Translation: Don’t shove words in my mouth and then pretend you’re the hero for chewing them up. 3. Slippery Slope The “Everything Will Collapse” Argument. One small change, and suddenly we’re tumbling into the apocalypse. Because why deal with nuance when you can predict doom? Example: You: “We should allow flexible work hours. ”Them: “Yeah, and next thing you know, no one will work at all, and society will crumble.” Counter: “Flexible hours don’t mean people stop working. It means they work smarter. Let’s not jump to Mad Max conclusions.” Translation: Calm down, Nostradamus. One step forward doesn’t always lead to a cliff. 4. Bandwagon Fallacy If Everyone Else Jumped Off a Bridge… This one’s like peer pressure in argument form. Just because everyone believes it doesn’t make it true. Example: Them: “Everyone I know says this diet works, so it must be good for you.” Counter: “A bunch of people believing something doesn’t make it true. Everyone used to think the Earth was flat too.” Translation: Popularity is a terrible judge of truth. Ask any middle school kid. 5. Appeal to Authority Because the “Expert” Said So. Dragging in a big name who has zero relevance to the topic. Example: Them: “My yoga instructor says this is the best investment strategy.” Counter: “Your yoga instructor might know how to do a perfect downward dog, but I don’t think they’re Warren Buffett.” Translation: Cool story. Now let’s hear from someone who knows what they’re talking about. 6. False Dichotomy Pick a Side. There Are Only Two. This is when they boil a complex issue down to two extreme choices. It’s lazy thinking disguised as decisiveness. Example: Them: “You’re either a cat person or a dog person.” Counter: “Or — hear me out — I can like both. Or neither. Because life isn’t a Disney movie.” Translation: There’s more than one flavor of ice cream. Stop making me choose between vanilla and vanilla. ‍ 7. Red Herring Look Over There! They throw in something completely irrelevant to distract you from the actual topic. It’s the argument equivalent of a toddler pointing at a shiny object. Example: You: “I think the camera quality on this phone isn’t great. ”Them: “Yeah, but feel how sleek the design is!” Counter: “The design is nice, but we’re talking about the camera. Stay with me here.” Translation: Stop trying to change the subject. I’m not that easy to distract. ‍ 8. False Cause Two Things Happened, So They Must Be Related. Just because two things happen together doesn’t mean one caused the other. Correlation is not causation. Example: Them: “Every time I wear this shirt, my team wins. It’s my lucky shirt!” Counter: “Or maybe your team is just good at sports. Your shirt isn’t part of the lineup.” Translation: Coincidences happen. Your shirt is not magic. Sorry. How to Survive These Conversations Without Losing Your Mind Stay Calm: Getting emotional is like handing them a free pass to dismiss you. Breathe. Channel your inner stoic.


Listen Hard: Make sure you actually understand what they’re saying before you respond. Misunderstanding them gives them ammo.


Be Prepared: Know these fallacies like the back of your hand. The more you spot them, the less they’ll trip you up.


Keep It Simple: Clear arguments win. Complexity is just noise. Bonus Tip: If the conversation is going nowhere and your sanity is at stake, walk away. NOE ONE ever looked back on their life and thought, “I wish I argued with more idiots.” Final Thought These tools won’t just help you in arguments. They’ll help you avoid the pointless ones. And in a world where arguing online is practically a hobby, that’s a superpower. So go forth, defend your sanity, and maybe — just maybe — help create a world where people think before they speak. Or not. At least you’ll be smarter. Until next time✌️ Ben. ‍ Ever been in a conversation where you felt like your brain was melting? You know the kind.

In this article, I’ll guide you through C# Testcontainers for MongoDB! I love using Testcontainers for local database work when I don’t want to think about managing the overhead of spinning up and tearing down a database, or managing something in the cloud. MongoDB is no exception here as the C# Testcontainers NuGet package that we have for MongoDB is a dream to work with. In this article, I’ll introduce you to the basics of Testcontainers. From there, I’ll demonstrate how simple it is to interact with your newly created database via the C# MongoDB.Driver NuGet package — almost like you wouldn’t even know there was a container spun up! Let’s dive into it. Overview of C# Testcontainers Testcontainers is an awesome NuGet package that can greatly enhance your testing and local development workflow when building .NET applications. It provides a simple and effective way to manage Docker containers, allowing you to spin up lightweight and isolated instances and have them tear down like nothing ever happened! That means with Testcontainers, you no longer have to worry about setting up and tearing down test databases or dealing with complex configuration files. It handles all the details of container management, making this process feel trivial — I sure wouldn’t want to handle this manually. Some of the key benefits of Testcontainers include: Its ability to provide a consistent and reproducible test environment. You can define the exact service version and configuration that you require, ensuring that your test results are reliable and consistent across different environments. The speed and flexibility it brings to your testing and development workflow. By using lightweight Docker containers, you can quickly spin up and tear down test environments on demand. No configuring cloud or shared resources ahead of time… Just on-the-fly awesomeness. Seamless integration with existing testing frameworks and tools in the DotNet ecosystem, such as Xunit, NUnit, and BenchmarkDotNet. This allows you to easily incorporate containerized service instances into your existing test suites without any major modifications. For this article, we’ll be focusing on how we can use C# Testcontainers for MongoDB in particular. Much of the advice covered here will be applicable to other services, especially databases, but we’ll keep our sights set on MongoDB. Setting Up Testcontainers in C# To get started with Testcontainers in C#, you’ll need to install and configure the necessary dependencies in your project. Follow the steps below to set up Testcontainers for MongoDB in C#. 1. Installing Testcontainers Generally, the first step would be to install the Testcontainers NuGet package in your C# project. You would open the NuGet Package Manager Console, and run the following command: Install-Package Testcontainers However, we need the MongoDB flavor of this package (I am using version 3.8.0 at the time of writing) which includes the base Testcontainers package. You can install it via the package manager user interface or with this command: Install-Package Testcontainers.MonogoDB 2. Configuring Testcontainers for MongoDB Once you have installed Testcontainers, you need to configure it for MongoDB. This involves setting up a MongoDB container with the required settings. Here is an example of how you can configure Testcontainers for MongoDB in C#: using Testcontainers.MongoDb;

MongoDbContainer container = new MongoDbBuilder()
    .WithImage("mongo:latest")
    .Build(); In the above example, we create a new instance of the , and specify the MongoDB image and port binding. The method sets the image for the MongoDB container, so using “mongo:latest” will always pull the latest image. MongoDbBuilder WithImage Optionally, we could use port binding to configure which ports we want to be using explicitly: using Testcontainers.MongoDb;

MongoDbContainer container = new MongoDbBuilder()
    .WithImage("mongo:latest")
    .WithPortBinding(1337, 27017)
    .Build(); The code above uses method binds the container’s port 27017 to the host machine’s port 1337. We’ll see in the upcoming sections that unless you have a specific need to bind ports, you can potentially just leave this be. We can get a dynamic connection string, which is very convenient! WithPortBinding 3. Starting and Stopping the MongoDB Container After configuring Testcontainers for MongoDB, you can start and stop the container as needed. Here are code examples for starting and stopping the container: To start the MongoDB container: await container.StartAsync(); To stop the MongoDB container: await _container.StopAsync(); Remember the MongoDbContainer type can be disposed of, so call to clean up when you’re ready. DisposeAsync Using C# Testcontainers for MongoDB in Practice Now that we’ve seen how to spin up and tear down containers, what are we supposed to do with them? We have plenty of options, and truly, the limit is your own imagination (and time, money, and other resources…)! Most people leverage C# Testcontainers for writing integration or . You can match up Testcontainers with xUnit or NUnit, for example, and write tests that interact with a real database. functional tests For me, I needed to go wire C# Testcontainers for MongoDB up to BenchmarkDotNet so I could ! A similar use case where I needed transient local databases, but not necessarily for a test framework. benchmark inserting records into MongoDB Regardless, we need to be able to connect to these MongoDB database containers from C#, and these next subsections will cover that. Connecting to C# Testcontainers for MongoDB with MongoDB.Driver Let’s assume you read the earlier sections and you have the correct MongoDB package installed for Testcontainers. If you skimmed ahead to this section, go back, read it, and get the right package. Otherwise, you’ll be scratching your head about why you can’t find the right dependencies! You’ll also need to get the MongoDB.Driver NuGet package installed. This is what we’re going to be using to establish a connection to the database container that we spun up. I have other articles you can read if you want more explanation on how MongoDB.Driver works in general: MongoDB in C#: Simplified Guide For Inserting Data MongoDB Filtering in C# – Beginner’s Guide For Easy Filters How To Delete Documents From MongoDB In C# – What You Need To Know How To Update MongoDB Documents in C# – What You Need To Know With the right packages ready to go, we can combine the code we saw earlier with some MongoDB driver code to get things glued together: using MongoDB.Bson;
using MongoDB.Driver;

using Testcontainers.MongoDb;

MongoDbContainer container = new MongoDbBuilder()
    .WithImage("mongo:latest")
    .Build();
await container.StartAsync();
string connectionString = container.GetConnectionString();

MongoClient mongoClient = new MongoClient(connectionString);
IMongoDatabase database = mongoClient.GetDatabase("test");
IMongoCollection<BsonDocument> collection = database.GetCollection<BsonDocument>("test"); In the example above, we can call on the newly spun-up MongoDB container from Testcontainers. The awesome part about this is that no matter how you configure your Testcontainer for MongoDB using the builder pattern we see in this code and earlier in the article, will get you what you need to connect. GetConnectionString() GetConnectionString() Because takes in a connection string as a single argument, it’s trivial to get access to the MongoDB database to start working with it right away! MongoClient Performing CRUD Operations on the MongoDB Testcontainer Now that we have our MongoDB Testcontainer set up and we have a connected to it, we can start performing CRUD operations on it. The connection details provided by the container instance made it a breeze to combine these two things, and truly, we can focus on just the MongoDB.Driver method calls for CRUD. MongoClient Here’s an example of performing a simple CRUD operation: // using code from earlier examples...

// Create
await collection.InsertOneAsync(new BsonDocument()
{
    ["Name"] = "Nick Cosentino",
});

// Read
var filterBuilder = Builders<BsonDocument>.Filter;
var filter = filterBuilder.Eq("Name", "Nick Cosentino");
var results = collection.Find(filter);

// Update
var updateBuilder = Builders<BsonDocument>.Update;
var update = updateBuilder.Set("Name", "Dev Leader");
collection.UpdateOne(filter, update);

// Delete
filter = filterBuilder.Eq("Name", "Dev Leader");
collection.DeleteOne(filter); Using the previous code snippets, we were already up and running with our MongoDB container instance and a . As a result, you can see in the code snippet above that we can directly work with our that we obtained from the prior setup. MongoClient IMongoCollection<BsonDocument> This helps illustrate that once you have the MongoDB docker container up and running via Testcontainers, you don’t have to treat things any special way once you connect to it! Wrapping Up C# Testcontainers for MongoDB To conclude, C# Testcontainers for MongoDB is an incredibly simple way to get a transient MongoDB data store up and running for your testing and development. While this article didn’t focus on specific use cases, hopefully, you have a better understanding of how transparent it feels to layer a MongoDB driver on top of Testcontainers to interact with MongoDB. Given that C# Testcontainers takes the headache out of the setup, teardown, and even connection string management, it’s an easy recommendation from me if you want to get up and running with MongoDB for local usage.

Easily Handle Faults And Retries With Polly In C#

Almost any web app that contains data needs a way to represent it succinctly and clearly to the user. However, most Python web development solutions do not provide an easy way to do this purely in . Python Thanks to the plethora of existing React components for creating graphs, an implementation for Python can be created to easily solve this problem. In this post, we’ll walk through how to build a web app purely in Python, which contains graphs that strike a balance between flexibility and ease of use. The graphs are easy to build but also easy to customize to your needs. For this project, we are going to use a new open-source dev tool called Reflex. 1. Getting started with your Python Web App If you face any problems here with installation check out more docs here: https://reflex.dev/docs/getting-started/installation/ $ pip install reflex $ reflex init 2. Creating an Interactive Graph In this example, we will create a live-streaming graph that updates every second with random data. We start by defining some initial data for our chart to use, as well as some imports we will use for the project: from typing import Any, Dict, List
import reflex as rx
import random
import asyncio

data = [
    {"name": "A", "uv": 10, "pv": 110, "amt": 210},
    {"name": "B", "uv": 20, "pv": 120, "amt": 230},
    {"name": "C", "uv": 30, "pv": 120, "amt": 240},
    {"name": "D", "uv": 30, "pv": 130, "amt": 210},
    {"name": "E", "uv": 20, "pv": 140, "amt": 230},
    {"name": "F", "uv": 40, "pv": 170, "amt": 250},
    {"name": "G", "uv": 50, "pv": 190, "amt": 260},
] Here stands for unique visitors, stands for page views and stands for amount. uv pv amt They are arbitrary values that we will use to populate our graph. Next, we define a class that will be used to store the data and update it with an event handler: StreamingState class StreamingState(rx.State):
    data: List[Dict[str, Any]] = data
    stream: bool = False

    def stop_stream(self):
        self.stream = False

    @rx.background
    async def start_stream(self):
        async with self:
            self.stream = True
        while self.stream:
            async with self:
                for i in range(len(self.data)):
                    self.data[i]["uv"] = random.randint(0, 100)
                    self.data[i]["pv"] = random.randint(100, 200)
                    self.data[i]["amt"] = random.randint(200, 300)
            await asyncio.sleep(3) Here, we define a method that will stop the stream when called. We also define a method that will start the stream. We use the decorator to run the method in the background. This allows us to update the data without blocking the UI. stop_stream start_stream @rx.background Remember to use when updating the state in a background task. async with self: Finally, we will define our UI using Reflex's new graphing components. We pass the data from our class to the component and reference the data key we want to use in component. We also add a button to start and stop the stream. StreamingState area_chart area The result is a live updating graph that looks like this: The code for this graph is below: def index():
   return rx.vstack(
     rx.recharts.area_chart(
        rx.recharts.area(
            data_key="pv",
            stroke="#82ca9d",
            fill="#82ca9d",
            type_="natural",
        ),
        rx.recharts.x_axis(
            data_key="name",
        ),
        rx.recharts.y_axis(),
        rx.recharts.legend(),
        data=StreamingState.data,
        width="100%",
        height=400,
    ),
    rx.hstack(
        rx.button(
            "Start Stream",
            on_click=StreamingState.start_stream,
            disabled=StreamingState.stream,
        ),
        rx.button(
            "Stop Stream",
            on_click=StreamingState.stop_stream,
        ),
        width="100%",
    ),
    width="100%",
)

# Add state and page to the app.
app = rx.App()
app.add_page(index)
app.compile() The last three lines define our app, add the graph component to the base route, and then compile our app. Now, we can run it with the terminal command. $ reflex run 3. Multiple Graphs We can add extra components to our chart to show the and data as well. We can also add a an component to show the data when we hover over the chart. area uv amt graphing_tooltip cartesian_grid Keep in mind the child coming first will be displayed in the back, so the order of the components matter. area The code for this graph is below: def index():
  return rx.vstack(

The Noonification: Turn GPT-4 Into Your Expert: Fine-Tuning Large Language Models Easily (9/20/2023)

In today's digital age, AI's capabilities seem limitless, don't they? Picture this: An AI that doesn't just perform general tasks but specializes in a specific domain, much like an expert in any field. Basically, your AI accountant, AI lawyer, or even AI doctor at a super low cost! What if I told you that turning a generalist AI into a specialist is not a distant dream but a reality you can achieve right now? Welcome to the world of fine-tuning Large Language Models. Today, we'll discuss this powerful technique to make them masters in any domain you desire. The only downside is that you still need some data, but much less than training a model from scratch! Fine-tuning is the magic wand that can transform a jack-of-all-trades AI model into a domain-specific maestro. Whether you want an AI to help with medical queries, navigate the world of finance, or even assist with customer support, fine-tuning is the answer. With the right techniques, these models can be adapted to provide specialized knowledge, ensuring that they're not just generalists but experts in the area you need. However, like all good things, there's a catch – and I've dived deep into this in today's video. For those eager to get their hands dirty and explore this phenomenon, I also run a little applied demo with a cool platform that offers a user-friendly way to jump right in. If you have ever wondered how to make the most out of large language models and mitigate biases and hallucination issues, fine-tuning is what you were looking for.

Real Time Data Processing: Easily Processing 10 Million Messages With Golang, Kafka and MongoDB

In this blog, I will be sharing a script that allows you to easily select a column in a Google Sheets spreadsheet and copy it to another spreadsheet while ensuring that the values are aligned in the same rows. Whether you're a Google Apps Script Developer or just someone looking to streamline their workflow, this script will be a helpful tool for you. This is Nibesh Khadka. I am a freelance Google Apps Script Developer and Content Creator. Referencing Columns Before Copying Copying a column from one sheet to another can be challenging if we don't have a unique column as a reference to put the values in the correct column. We can use columns like ID, Email, or any other column that exists in both sheets as a reference. In this article, we'll create a spreadsheet with two sheets and use the "ID" column as a reference to copy the "Name" column from to . Sheet1 Sheet2 You can just download and use this sheet or create your own. You can either follow the steps or download the complete code from the git . repository Script Editor Now this is the bound script. So, open the spreadsheet you want to use for this project and open the script editor from there. HTML Form For this project, unlike in the one, we'll be using with HTML instead of UI prompts because we'll need multiple input boxes for this project. previous Custom Dialog Boxes Create a new file in your script editor. Then copy and paste the following codes HTML <!DOCTYPE html>
<html>
<head>
  <base target="_top">
  
</head>

<body>
  <form onsubmit="formSubmitHandler(event)">
    <h2>Source Sheet</h2>
    <label for="sourceSheet">Source Sheet Name:</label><br>
    <input type="text" id="sourceSheet" name="sourceSheet"><br>
    <label for="referenceColumn">Reference Column Name</label><br>
    <input type="text" id="referenceColumn" name="referenceColumn"><br>
    <label for="sourceColumn">Source Column To Copy From:</label><br>
    <input type="text" id="sourceColumn" name="sourceColumn"><br>
    <hr>
    <h2>Target Sheet</h2><br>
    <label for="targetSheet">Target Sheet Name:</label><br>
    <input type="text" id="targetSheet" name="targetSheet"><br>
    <label for="targetReferenceColumn">Reference Column Name</label><br>
    <input type="text" id="targetReferenceColumn" name="targetReferenceColumn"><br>
    <label for="targetColumn">Target Column To Copy To:*</label><br>
    <input type="text" id="targetColumn" name="targetColumn"><br>
    

    <input type="submit" value="Submit" />

  </form>

  <script>
    function formSubmitHandler(event) {

      const sourceSheet = event.target['sourceSheet'].value;
      const referenceColumn = event.target['referenceColumn'].value;
      const sourceColumn = event.target['sourceColumn'].value;
      const targetSheet = event.target['targetSheet'].value;
      const targetReferenceColumn = event.target['targetReferenceColumn'].value;
      const targetColumn = event.target['targetColumn'].value ?? "";
      const data = [sourceSheet, referenceColumn, sourceColumn, targetSheet, targetReferenceColumn, targetColumn];

      // call server side function
     google.script.run.withSuccessHandler(closeDialog).setTargetColumns(data);

      event.preventDefault();

    }

    function closeDialog() { google.script.host.close() }
  </script>
</body>
</html> There are two to notice here. script runners is used to link the function in the form in the front-end to the function in the backend(script) code during operation success, in this case, is the backend function we're using. withSuccessHandler() setTargetColumns() which is used to close the dialog box. We are using it with to call the backend and then close the dialog box. close() withSuccessHandler() When rendered the Form looks like this: Feel free to style the HTML Form to make it more beautiful. In this HTML form you'll have to provide six pieces of information: The name of the Source Worksheet. The name of the Reference Column in the source sheet. The name of the Source Column in the source sheet whose value is to be copied. The name of the Target Worksheet where the value is to be copied. The name of the Reference Column in the target sheet. The name of the Target Column in the target sheet, that will hold the copied value. Copy Column to Different Sheet Now let's write the script to copy the values from one column to another. function renderForm() {
  const html = HtmlService.createHtmlOutputFromFile('form')
    .setWidth(400)
    .setHeight(600);// play with dimension to fit your need
  SpreadsheetApp.getUi() 
    .showModalDialog(html, "Copy Column With Reference");
}

//["Sheet1", "ID", "Name", "Sheet2", "ID", "Name"]
function setTargetColumns(data) {
  try {
    const sourceSheetName = data[0];
    const referenceColumnName = data[1];
    const sourceColumnName = data[2];
    const targetSheetName = data[3];
    const targetReferenceColumnName = data[4];
    const targetColumnName = data[5];

    // get sheet and data
    const sheet = SpreadsheetApp.getActiveSpreadsheet();
    const sourceSheet = sheet.getSheetByName(sourceSheetName);

    const sourceSheetData = sourceSheet.getDataRange().getValues();
    const sourceSheetLastRow = sourceSheetData.length;
    const sourceSheetLastColumn = sourceSheetData[0].length;
    // get header column of source sheet
    const sourceSheetHeader = sourceSheet.getRange(1, 1, 1, sourceSheetLastColumn).getValues().flat();

    // find the index of the given column names
    const referenceColumnIndex = sourceSheetHeader.indexOf(referenceColumnName.trim());
    if (referenceColumnIndex === -1) throw "Reference Column Not Found";

    const sourceColumnIndex = sourceSheetHeader.indexOf(sourceColumnName.trim());
    if (sourceColumnIndex === -1) throw "Source Column Not Found"; // if the name is not found then throw error

    const sourceSheetData2 = [sourceSheet.getRange(2, referenceColumnIndex + 1, sourceSheetLastRow, 1).getValues().flat(), sourceSheet.getRange(2, sourceColumnIndex + 1, sourceSheetLastRow, 1).getValues().flat()]


    const targetSheet = sheet.getSheetByName(targetSheetName);
    const targetSheetData = targetSheet.getDataRange().getValues();
    const targetSheetLastRow = targetSheetData.length;


    const targetReferenceColumnIndex = sourceSheetHeader.indexOf(targetReferenceColumnName.trim());
    if (targetReferenceColumnIndex === -1) throw "Target Sheets Reference Column Not Found";

    const targetColumnIndex = sourceSheetHeader.indexOf(targetColumnName.trim());
    if (targetColumnIndex === -1) throw "Target Sheet's Target Column Not Found";

    const targetSheetRefData = targetSheet.getRange(2, targetReferenceColumnIndex + 1, targetSheetLastRow - 1, 1).getValues().flat();
    const targetSheetColData = targetSheet.getRange(2, targetColumnIndex + 1, targetSheetLastRow - 1, 1).getValues();


    for (let i = 0; i < sourceSheetData2[0].length; i++) {
      for (let j = 0; j < targetSheetRefData.length; j++) {
        if (targetSheetRefData[j] === sourceSheetData2[0][i]) {
          targetSheetColData[j] = [sourceSheetData2[1][i]];
          break;
        }
        continue;
      }
    }
    // set new values 
    targetSheet.getRange(2, targetColumnIndex + 1, targetSheetLastRow - 1, 1).setValues(targetSheetColData);

  } catch (e) {
    // alert error
    SpreadsheetApp.getUi().alert(`Error: ${e}`)
  }
}
