Node.js itself is not single-threaded.

Node.js itself is not single-threaded.

Node.js developers often confuse the main single-threaded event loop with Node.js entirely.

When a Node.js app is running, it automatically creates 4 threads under the worker pool for blocking tasks.

So at any given time, there are at least five threads.

This worker pool is managed by Libuv.

The blocking tasks are mainly I/O-bound and CPU-intensive.

**1. I/O bound**
a. DNS: dns.lookup(), dns.lookupService()
b. File system except fs.FSWatcher()

**2. CPU-intensive tasks**
a. Some crypto methods such as crypto.pbkdf2(), crypto.scrypt(), crypto.randomBytes(), crypto.randomFill(), crypto.generateKeyPair()

b. All zlib APIs other than those using libuv thread pool synchronously.

The main thread/event loop works for JavaScript execution as usual, but the worker pool takes care of blocking tasks for the main loop.

So, Node.js shouldn't be confused.

Thanks for reading.

Rewrites are a symptom of bad initial engineering
Tags: softwareengineering, beginners, discuss, learning
Published: 2024-04-20 16:25:45

I was prone to this problem at the beginning of my career, I would want to rewrite everything from the ground-up if I got this chance or I felt that the initial implementation did not "scale" well.

As I progressed in my career I started to realize that rewriting your application is a symptom of bad initial engineering. The application was not thought from a systems design perspective and the use of SOLID and other principles allows you to manage application code better in a system that is ever-changing.

If you come to a point where you need to rewrite an application then it just means that you did not spend the necessary time to design the foundation of the system which takes into consideration ever-changing business requirements.

เว็บโฮสติ้งเป็นหัวใจสำคัญของเว็บไซต์ใดๆ
Published: 2024-04-21 05:10:01

สิ่งที่ทำให้ผู้ให้บริการที่เชื่อถือได้เหล่านี้แตกต่างออกไปคือความมุ่งมั่นอย่างแน่วแน่ต่อความน่าเชื่อถือ พวกเขาลงทุนในศูนย์ข้อมูลล้ำสมัยที่ติดตั้งระบบสำรองเพื่อให้มั่นใจถึงเวลาทำงานสูงสุดและลดความเสี่ยงของการหยุดชะงักของบริการ ความน่าเชื่อถือนี้เป็นสิ่งจำเป็นสำหรับธุรกิจที่ไม่สามารถให้เว็บไซต์ของตนไม่สามารถเข้าถึงได้ เนื่องจากการหยุดทำงานเพียงไม่กี่นาทีก็อาจส่งผลให้สูญเสียรายได้และสร้างความเสียหายต่อชื่อเสียงได้

นอกจากนี้ ผู้ให้บริการเว็บโฮสติ้งที่เชื่อถือได้ยังให้ความสำคัญกับความปลอดภัย โดยใช้มาตรการที่แข็งแกร่งเพื่อปกป้องข้อมูลและเว็บไซต์ของลูกค้าจากภัยคุกคามทางไซเบอร์ ซึ่งรวมถึงไฟร์วอลล์ การสแกนมัลแวร์ การเข้ารหัส SSL และการตรวจสอบความปลอดภัยเป็นประจำเพื่อระบุและบรรเทาช่องโหว่ในเชิงรุก เนื่องจากการโจมตีทางไซเบอร์มีความซับซ้อนมากขึ้น ธุรกิจและผู้สร้างเว็บไซต์จึงต้องการผู้ให้บริการโฮสติ้งที่พวกเขาสามารถไว้วางใจในการปกป้องทรัพย์สินดิจิทัลของตน

นอกจากความน่าเชื่อถือและความปลอดภัยแล้ว องค์กรชั้นนำและผู้สร้างเว็บไซต์ยังต้องพึ่งพาผู้ให้บริการเว็บโฮสติ้งที่เชื่อถือได้สำหรับความเชี่ยวชาญด้านเทคนิคและการสนับสนุน ไม่ว่าจะเป็นการแก้ไขปัญหาทางเทคนิค การเพิ่มประสิทธิภาพเซิร์ฟเวอร์ หรือการปรับขนาดทรัพยากรเพื่อรองรับการเติบโต ทีมสนับสนุนที่มีความรู้พร้อมให้บริการทุกวันตลอด 24 ชั่วโมงเพื่อช่วยเหลือลูกค้าในทุกขั้นตอน การสนับสนุนส่วนบุคคลในระดับนี้มีคุณค่าอย่างยิ่ง โดยเฉพาะอย่างยิ่งสำหรับผู้ที่ไม่มีพื้นฐานด้านการพัฒนาเว็บหรือการจัดการเซิร์ฟเวอร์

Get Unique Elements in a Python List

title: Get Unique Elements in a Python List

In Python we can get the unique elements from a list by converting it to a set with `set()`. Sets are a [collection of **unique** elements](https://docs.python.org/3/tutorial/datastructures.html#sets):

```python
values = [1, 1, 1, 2, 2, 3, 3, 3, 3]

values = set(values)

print(values)
```

Output:

```
{1, 2, 3}
```

And if we still need a list instead of a set, we can easily convert back to a list using `list()`:

```python
values = [1, 1, 1, 2, 2, 3, 3, 3, 3]

# convert to set to get unique values
values = set(values)
# convert back to list
values = list(values)

print(values)
```

Output:

```
[1, 2, 3]
```

---

I learned this trick after realizing that unfortunately Python doesn't have a [`uniq()` method like Ruby](https://apidock.com/ruby/Array/uniq) that does this exact thing.

There's also other ways of getting unique values from a list that you can read about in [this GeeksforGeeks article](https://www.geeksforgeeks.org/python-get-unique-values-list/). I didn't cover the other cases because I feel like the easiest way is to use `set()`.

Discover how Service Workers can revolutionize your web applications, ensuring they remain functional even offline. Accompanied by video demonstrations, witness the transformation from a traditional web app to one empowered by Service Workers.

**Understanding Service Workers:**

Service Workers act as silent guardians, caching essential resources and enabling offline functionality. By intercepting network requests, they empower web apps to function seamlessly even when connectivity is lost.

**Implementing Service Workers:**

Integrating Service Workers into your web app is simple. Register a Service Worker script in your app's code to control certain browsing aspects, including resource caching for offline use.

**Simulating Offline Scenarios:**

Use browser developer tools to simulate offline conditions for testing. Throttle the network connection to observe how your web app responds in offline mode, optimizing its functionality accordingly.

**Creating an Offline-First Experience:**

Design your web app with offline accessibility in mind, ensuring smooth user experiences regardless of connectivity.

**Testing and Deployment:**

Thoroughly test your offline-ready web app before deployment. Simulate various network conditions to confirm reliable performance. Deploy with confidence to provide users with a seamless experience anywhere, anytime.

**Conclusion:**
Service Workers offer a solution to unreliable internet connections, transforming web apps into dependable companions. Embrace offline accessibility today to deliver web apps that work flawlessly, regardless of connectivity challenges

Doge Dreams: Experts Predict 700% Surge in Dogecoin Value – Is $1 Within Reach?
Tags: cryptocurrency, dogecoin, bitcoin
Published: 2024-04-23 10:20:46

[Dogecoin Prediction](https://coinpedia.org/price-prediction/dogecoin-price-analysis/): Analysts Bullish on DOGE's Future

Dogecoin (DOGE) has proven its resilience once again, with a 2.5% price uptick in the last 24 hours, reaching $0.1607 in trading value. Analysts like Altcoin Sherpa and Ali Martinez have recently shared positive forecasts for DOGE's trajectory, suggesting further growth potential and the possibility of outperforming other tokens.

Dogecoin's Strength in 2024

Following closely in Bitcoin's footsteps, DOGE has experienced its share of ups and downs in recent months. On March 28, DOGE hit a yearly high of $0.2292, cementing its position as the 9th largest cryptocurrency, boasting nearly 100% year-to-date growth. Despite market fluctuations, DOGE has consistently rebounded and attracted investor attention.

Altcoin Sherpa is particularly bullish on DOGE's prospects for 2024, recommending averaging between $0.12 and $0.14. Highlighting DOGE's historical consolidation phase lasting almost two years, Sherpa believes the coin is primed for significant price appreciation in the future.

700% Price Uptrend Toward $1

Similarly, crypto analyst Ali Martinez sees potential for DOGE to rally towards $1 in the coming weeks, representing a remarkable 700% uptrend from current levels. Martinez notes DOGE's recurring price patterns, particularly after breaking out of a descending triangle formation.

Despite these optimistic outlooks, DOGE faces resistance levels hindering its recovery after a recent 21% price decline. The $0.1633 level has posed a significant barrier in the past 10 days, with additional obstacles at $0.1739, $0.1938, and $0.1998 on the path to $0.200.

It's crucial to recognize that DOGE's future trajectory is closely tied to Bitcoin's performance and various market dynamics. As we navigate through 2024, the potential for a bullish breakout and other factors will continue to shape Dogecoin's journey.
📦 Put dev dependencies in tools.go
Tags: go, todayilearned, todayisearched
Published: 2024-04-24 00:42:20

**TL;DR:** Use a `tools.go` file with `//go:build tools` to list `import _ "github.com/octocat/somedevtool"` to stop `go mod tidy` from removing them.

```go
//go:build tools

package tools

import (
	_ "github.com/melbahja/got/cmd/got"
	_ "github.com/arkady-emelyanov/go-shellparse"
)
```

<sup>💡 `go mod tidy` doesn't care if the package is cmd or lib</sup>

Then you can use whatever you list in `tools.go` in `//go:generate` and `task.go`!

```go
package mylib

//go:generate -command got go run github.com/melbahja/got/cmd/got

import (
  "fmt"
  _ "embed"
)
//go:generate got https://example.org/image.png -o image.png
//go:embed image.png
var imagePNG []byte
```

```go
// task.go
//go:build ignore

package main

import "github.com/arkady-emelyanov/go-shellparse"

func main() {
  // ...
}
```
