خرید قهوه از فروشگاه دمی نو
Published: 2024-07-04 19:07:57

**[خرید قهوه](https://damyno.com/)** با کیفیت نیازمند توجه به چندین نکته مهم است که می‌تواند تجربه نوشیدن قهوه را بهبود بخشد. در این مقاله، به بررسی نکات کلیدی برای خرید قهوه از فروشگاه قهوه دمی نو می‌پردازیم.


**1. نوع دانه قهوه
**
دانه‌های قهوه به دو نوع اصلی تقسیم می‌شوند: عربیکا و روبوستا.
عربیکا: این نوع قهوه دارای طعم ملایم‌تر و عطر بیشتری است و معمولاً دارای قیمتی بالاتر از روبوستا است. دانه‌های عربیکا بیشتر در مناطق مرتفع کشت می‌شوند.
روبوستا: این نوع قهوه دارای طعم قوی‌تر و تلخی بیشتری است. روبوستا مقاومت بیشتری در برابر بیماری‌ها دارد و کافئین بیشتری نسبت به عربیکا دارد. این نوع دانه بیشتر در مناطق کم ارتفاع کشت می‌شود.


**2. تازگی دانه قهوه
**
تازگی دانه قهوه یکی از مهمترین عواملی است که بر طعم و عطر قهوه تأثیر می‌گذارد. بهتر است دانه‌های قهوه را به صورت تازه‌برشته خریداری کنید و تنها به اندازه نیاز خود آسیاب کنید.


**3. منطقه کشت
**
منطقه کشت دانه‌های قهوه نیز بر طعم نهایی آن تأثیرگذار است. هر منطقه دارای ویژگی‌های خاصی است که به دانه‌های قهوه طعم و عطری منحصر به فرد می‌بخشد. برای مثال:
آفریقا: قهوه‌های این منطقه معمولاً دارای طعم‌های میوه‌ای و گلی هستند.
آمریکای مرکزی و جنوبی: قهوه‌های این مناطق اغلب دارای طعم‌های شکلاتی و کاراملی هستند.
آسیا: قهوه‌های این منطقه معمولاً دارای طعم‌های خاکی و ادویه‌ای هستند.


**4. روش فرآوری
**
روش فرآوری دانه‌های قهوه نیز بر طعم نهایی تأثیر دارد. سه روش اصلی فرآوری عبارتند از:
شسته شده (Washed): این روش باعث می‌شود که طعم‌های تمیزتر و شفاف‌تری در قهوه وجود داشته باشد.
طبیعی (Natural): این روش منجر به ایجاد طعم‌های میوه‌ای و شیرین‌تر می‌شود.
عسل (Honey): این روش ترکیبی از دو روش بالا است و طعم‌هایی بینابینی ایجاد می‌کند.


5. رست (برشته شدن)

درجه رست قهوه نیز عامل مهمی در تعیین طعم نهایی آن است:
رست روشن: این نوع رست طعم‌های اسیدیته بالا و میوه‌ای ایجاد می‌کند.
رست متوسط: این نوع رست تعادلی بین طعم‌های اسیدیته و تلخی دارد و طعم‌های کاراملی و شکلاتی برجسته‌تر می‌شوند.
رست تیره: این نوع رست دارای طعم‌های تلخ و دودی است و اسیدیته کمتری دارد.


****6. بسته‌بندی
****بسته‌بندی مناسب نقش مهمی در حفظ تازگی دانه‌های قهوه دارد. بسته‌بندی‌هایی که دارای سوپاپ یک‌طرفه هستند، به خروج گازهای تولید شده توسط قهوه اجازه می‌دهند و در عین حال از ورود هوا جلوگیری می‌کنند.


**7. تاریخ تولید
**همیشه به تاریخ تولید و رست دانه‌های قهوه توجه کنید. دانه‌های قهوه تازه‌تر طعم و عطر بهتری دارند. تلاش کنید قهوه‌ای را خریداری کنید که حداکثر چند هفته از تاریخ رست آن گذشته باشد.


**8. آسیاب قهوه
**اگر امکانش را دارید، دانه‌های قهوه را به صورت کامل خریداری کرده و خودتان در منزل آسیاب کنید. این کار به حفظ تازگی و عطر قهوه کمک می‌کند. آسیاب‌های قهوه به دو نوع دستی و برقی موجود هستند که هر کدام مزایا و معایب خاص خود را دارند.

What are the differences between hosting websites through Git and AWS?
Published: 2024-07-04 19:02:10

**Git can host static websites, but for full-stack applications involving dynamic data and backend changes, cloud services like AWS and Azure are necessary. I'm using AWS to host my complex website, leveraging free EC2 instances. I'm deploying my code to AWS instances using Git commands via PuTTY. I'm installing Apache server for hosting my website. Ensure Git, React, Node.js, and npm are installed before cloning the repo in PuTTY.**
Raw Types and Backward Compatibility
Tags: java, programming, learning, beginners
Published: 2024-07-04 18:55:11

A generic class or interface used without specifying a concrete type, called a raw type, enables backward compatibility with earlier versions of Java. You can use a generic class without specifying a concrete type like this:

`GenericStack stack = new GenericStack(); // raw type`

This is roughly equivalent to

`GenericStack<Object> stack = new GenericStack<Object>();`

A generic class such as **GenericStack** and **ArrayList** used without a type parameter is called a _raw type_. Using raw types allows for backward compatibility with earlier versions of Java. For example, a generic type has been used in **java.lang.Comparable** since JDK 1.5, but a lot of code still uses the raw type **Comparable**, as shown in the code below:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/1tc9wj6alvb83zue02e6.png)

**Comparable o1** and **Comparable o2** are raw type declarations. Be careful: _raw types are unsafe_. For example, you might invoke the max method using

Max.max("Welcome", 23); // 23 is autoboxed into new Integer(23)

This would cause a runtime error, because you cannot compare a string with an integer object. The Java compiler displays a warning on line 3 when compiled with the option **–Xlint:unchecked**, as shown in Figure below.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/bifcvtj2srfaegm0hd9k.png)

A better way to write the **max** method is to use a generic type, as shown in the code below.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/p1ur2ku3b1lqt3hnwsvw.png)

If you invoke the **max** method using

`// 23 is autoboxed into new Integer(23)
MaxUsingGenericType.max("Welcome", 23);`

a compile error will be displayed, because the two arguments of the **max** method in **MaxUsingGenericType** must have the same type (e.g., two strings or two integer objects). Furthermore, the type **E** must be a subtype of **Comparable<E>**.

As another example, in the following code you can declare a raw type **stack** in line 1, assign **new GenericStack<String>** to it in line 2, and push a string and an integer object to the stack in lines 3 and 4.

`1 GenericStack stack;
2 stack = new GenericStack<String>();
3 stack.push("Welcome to Java");
4 stack.push(new Integer(2));`

However, line 4 is unsafe because the stack is intended to store strings, but an **Integer** object is added into the stack. Line 3 should be okay, but the compiler will show warnings for both line 3 and line 4, because it cannot follow the semantic meaning of the program. All the compiler knows is that stack is a raw type, and performing certain operations is unsafe. Therefore, warnings are displayed to alert potential problems.
I Am Done With Self-Hosting

description: Changes on the home front
---

This is a personal post on why, after almost ten years, I am no longer self-hosting my blog, mail and other servers.

First, a clarification: up until now a lot of my data has been hosted on various virtual private server (VPS) providers. This may walk up to the line between proper self-hosting and ... something else. Still, I continue to call what I was doing self-hosting, not least because data I felt needed to stay private remained on servers physically under my control. I also think it qualifies because I was still fully responsible for OS-level maintenance of my VPS.

Pedantry aside, that maintenance was a primary driver for moving to a different hosting model. I have spent long enough maintaining Linux and OpenBSD servers that the excitement has long since worn off, and so giving time to it on weekends and holidays became untenable in the face of other options. There are services run by companies I trust that will host my email and most other data I might care to access remotely. They will even apply end-to-end encryption to the majority of that data. This is far from a zero trust arrangement, I admit. Still, the companies I have migrated to have cleared a threshold that I am comfortable with for the data they are hosting.

Plus, these companies have better availability guarantees than I could ever hope to achieve on my own. For example, my VPS was configured to forward incoming mail through a Wireguard VPN into a mail server hosted at my home. But as a result, if the power went out at my house, email service would go down. This was fine most of the time, but when I was on vacation the issue could persist until I got home to reboot the necessary hardware. Spending my vacation anxious about my servers came to seem like a ridiculous trade in exchange for more control over my data.

Probably the biggest surprise was that providers often have free tiers that are sufficient for my needs, meaning I'm actually paying less in hosting fees than I was before. I stand to make back even more if I sell hardware I'm not using at the moment (although I'm pretty good at coming up with new uses).

But mostly I'm glad to get the time back. I'll use it to spend more time with my family, or maybe write more. At the very least I'll be more present on vacation.
Generic Methods
Tags: java, programming, learning, beginners
Published: 2024-07-04 18:11:09

A generic type can be defined for a static method. You can define generic interfaces (e.g., the **Comparable** interface in Figure below (b)) and classes (e.g., the **GenericStack** class in [here](https://dev.to/paulike/defining-generic-classes-and-interfaces-1a03)).

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/zlnyojfx6ha8ltqyqb8e.png)

You can also use generic types to define generic methods. For example, the code below defines a generic method **print** (lines 13–17) to print an array of objects. Line 9 passes an array of integer objects to invoke the generic **print** method. Line 10 invokes **print** with an array of strings.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/9m5vs4a7e3saq1r8ax6s.png)

To declare a generic method, you place the generic type **<E>** immediately after the keyword **static** in the method header. For example,

`public static <E> void print(E[] list)`

To invoke a generic method, prefix the method name with the actual type in angle brackets. For example,

`GenericMethodDemo.<Integer>print(integers);
GenericMethodDemo.<String>print(strings);`

or simply invoke it as follows:

`print(integers);
print(strings);`

In the latter case, the actual type is not explicitly specified. The compiler automatically discovers the actual type.

A generic type can be specified as a subtype of another type. Such a generic type is called _bounded_. For example, the code below revises the **equalArea** method in [TestGeometricObject.java](https://dev.to/paulike/abstract-classes-2ee5), to test whether two geometric objects have the same area. The bounded generic type **<E extends GeometricObject>** (line 9) specifies that E is a generic subtype of **GeometricObject**. You must invoke **equalArea** by passing two instances of **GeometricObject**.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/96yk0uns45p74jhcz658.png)

An unbounded generic type **<E>** is the same as **<E extends Object>**. To define a generic type for a class, place it after the class name, such as **GenericStack<E>**. To define a generic type for a method, place the generic type before the method return type, such as **<E> void max(E o1, E o2)**.
Caching & Memoization with state variables
Tags: perl, caching, memoization
Published: 2024-07-04 18:08:13

(This is a cross post from [B.P.O](https://blogs.perl.org/users/chrisarg/2024/07/caching-memoization-with-state-variables.html) ).

Chapter 3 of [Higher Order Perl]<(https://hop.perl.plover.com/) describes various approaches to memoization of an expensive function: private cache and the Memoize module. The book was written in 2005 (Perl was at version 5.8 back then) , so it does not include another way for function caching that is now available : caching through <strong>state</strong> variables (introduced in Perl 5.10). The Fibonacci example considered in HOP also requires the ability to initialize state hash variables (available since Perl 5.28). The code below contrasts the implementation with a state variable v.s. the memoize module:

```perl
use v5.38;
use Time::HiRes qw(time);
use Memoize;

sub fib_cache_with_state ($number) {
    state %fib = ( 0 => 0, 1 => 1 );
    unless ( exists $fib{$number} ) {
        $fib{$number} = fib_cache_with_state( $number - 1 ) +
          fib_cache_with_state( $number - 2 );
    }
    return $fib{$number};
}

memoize 'fib';

sub fib ($number) {
    return $number if $number < 2;
    return fib( $number - 1 ) + fib( $number - 2 );
}

my $number = 80;

## using the memoize module
my $start_time = time;
my $fi1        = fib($number);
my $end_time   = time;
my $dt1        = $end_time - $start_time;

## using a state variable to memoize
$start_time = time;
my $fib2 = fib_cache_with_state($number);
$end_time = time;
my $dt2 = $end_time - $start_time;

printf "Fibonacci of %d with the memoize module took : %.2g\n", $number, $dt1;
printf "Fibonacci of %d with a  state variable  took : %.2g\n", $number, $dt2;

printf "Speedup state var /memoize module: %.2g\n", $dt1 / $dt2;
say "Difference in calculations : ", $fi1 - $fib2;

```

State variable is  faster for CPUs , but the Memoize module is faster for humans. Both of them are great tricks to know :)
Coding Ninjas Job Bootcamp review by an alumni
Published: 2024-07-04 14:28:26

My name is Abhishek Goswami, and I’m currently working on my own tech startup. I decided to join the bootcamp after hearing many success stories and learning about the journeys of others. When I first signed up, my goal was to gain new skills and knowledge that would help me advance in my career.

But the bootcamp exceeded my expectations in many ways. Its structured path and module deadlines kept me on track and motivated. Before starting the bootcamp, I struggled with understanding advanced concepts in web development, especially in backend programming. However, the structured approach of the bootcamp and the hands-on projects helped me overcome these challenges. For instance, I initially found it challenging to grasp the concepts of RESTful APIs and how to integrate them into web applications. Through the bootcamp, I not only learned the theory but also implemented multiple API integrations in a project where I developed a real-time chat application.

The program was comprehensive, covering all the important topics needed to become a full-stack developer. I improved my skills and knowledge through the many challenging problems presented during the course. For example, I encountered difficulties in optimizing database queries for performance in one of the projects. With the guidance of experienced mentors and the support of my peers, I learned advanced techniques and best practices that significantly enhanced my database management skills.

The job assistance component of the program was exceptional. We were required to achieve a certain level of proficiency, and the program arranged interviews with reputable companies. They provided great support throughout the process, making the job search much smoother and more manageable. The Teaching Assistants (TAs) were always there to help, which created many memorable and impactful moments for me. For example, during one of the mock interviews arranged by the TAs, I received detailed feedback that significantly improved my interviewing skills.

The instructors and mentors were knowledgeable and approachable. Their video explanations were clear, and they went above and beyond to ensure I understood the material. One mentor, in particular, helped me understand the intricacies of deploying applications to cloud platforms like AWS, which was a vital skill for my job.

Overall, I found the program to be well-organized and efficient in terms of its structure and curriculum. If you are looking for a structured path, I would advise you to join this bootcamp because everything is well-organized here. I highly recommend this bootcamp to anyone interested in becoming a full-stack developer.

JDBC and Streams have never been simpler
Tags: jdbc, lambda, java, functional
Published: 2024-07-04 17:51:24

### Just updated a library which makes life much easier when speaking about databases...
When streams were introduced in java I got myself thinking of how I can leverage it with databases. It is "pretty common" task to write SQL queries and process the results within Java. And the more I was ought to deal with prepared statements, result sets, all those `SQLException`s etc., the more I was disappointed. Searching the WEB for solutions where I wanted to find two worlds collided conveniently - I found no suitable one! Of course there are many libraries that afford some, but neither of them suited me. I wanted something else. Therefore I decided to write one myself for myself.

#### My goals...

...were based on my background experience:

1. No prepared boilerplate and `SQLException`s
2. Executing arbitrary scripts
3. Minimal configuration
4. "Real" streams (lazily data fetching)
5. Raw SQL
6. Database is just a method invocation

and some others - don't remember them all :)

So after some time I ended up with this:

### A brief

1 - Maven: 
```
<dependency>
  <groupId>com.github.buckelieg</groupId>
  <artifactId>jdbc-fn</artifactId>
  <version>1.0</version>
</dependency>
```
2 - Setup:
```
DB db = DB.builder()
        .withMaxConnections(10)
        .build(() -> DriverManager.getConnection("vendor-specific-string"));
```
3 - Select:
```
Collection<String> names = db.select("SELECT name FROM users WHERE ID IN (?, ?)", 1, 2).execute(rs -> rs.getString("name")).collect(Collectors.toList());
```

Happy to share: [jdbc-fn](https://buckelieg.github.io/jdbc-fn/) project.
Defining Generic Classes and Interfaces
Tags: java, programming, learning, beginners
Published: 2024-07-04 17:49:00

A generic type can be defined for a class or interface. A concrete type must be specified when using the class to create an object or using the class or interface to declare a reference variable. Let us revise the stack class in [Case Study: A Custom Stack Class](https://dev.to/paulike/case-study-a-custom-stack-class-2npc), to generalize the element type with a generic type. The new stack class, named **GenericStack**, is shown in Figure below and is implemented in the code below.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ply9g2dg7s2vubblwi5s.png)


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/j89l1zezjgx74kaizf0z.png)

The following example creates a stack to hold strings and adds three strings to the stack:

`GenericStack<String> stack1 = new GenericStack<>();
stack1.push("London");
stack1.push("Paris");
stack1.push("Berlin");`

This example creates a stack to hold integers and adds three integers to the stack:

`GenericStack<Integer> stack2 = new GenericStack<>();
stack2.push(1); // autoboxing 1 to new Integer(1)
stack2.push(2);
stack2.push(3);`

Instead of using a generic type, you could simply make the type element **Object**, which can accommodate any object type. However, using generic types can improve software reliability and readability, because certain errors can be detected at compile time rather than at runtime. For example, because **stack1** is declared **GenericStack<String>**, only strings can be added to the stack. It would be a compile error if you attempted to add an integer to **stack1**.

To create a stack of strings, you use **new GenericStack<String>()** or **new GenericStack<>()**. This could mislead you into thinking that the constructor of **GenericStack** should be defined as

`public GenericStack<E>()`

This is wrong. It should be defined as

`public GenericStack()`

Occasionally, a generic class may have more than one parameter. In this case, place the parameters together inside the brackets, separated by commas—for example,

`<E1, E2, E3>`

You can define a class or an interface as a subtype of a generic class or interface. For example, the **java.lang.String** class is defined to implement the **Comparable** interface in the Java API as follows:

`public class String implements Comparable<String>`
