High-level overview of Amazon Athena
Tags: datascience, serverless, cloud, aws
Published: 2023-11-21 19:44:00

Athena is a serverless query service to help you analyze the data stored in Amazon S3 buckets.

And to analyze this data, you're going to use the standard SQL language to query the files.
Behind the scenes, Athena is built on the **Presto engine**, which uses the SQL language.

So the idea is that you are going to load data into your S3 bucket, and then you would use the Athena service to query and analyze this data in Amazon S3 without moving it.

So Athena is **serverless**, and it analyzes directly your data living in your S3 bucket.
So it **supports different formats**, such as _CSV_, _JSON_, _ORC_, _Avro_, and _Parquet_, and possibly others.

And the pricing is very simple, you're just going to pay a fixed amount per terabytes of data scanned.
You don't need to provision any database again, because the whole service is serverless.

So Athena is commonly used with another tool, called Amazon **QuickSight** to create reports and dashboards.
Amazon Quicksight connects to Athena, which connects to your S3 buckets.

Now, the use cases for Amazon Athena are to do ad hoc queries, **Business Intelligence**, **Analytics**, **Reporting**, and to **analyze and query any kind of logs that originates from your AWS services**.
So it could be your _VPC flow logs_, your _load balancer logs_, your _CloudTrail trails_, and so on.


Because you pay for the amount of data scanned per terabyte, you need to use a type of data where you're going to scan less data.
And for this, you can use a columnar data type for cost-savings, because you only scan the columns you need.
So therefore, the recommended formats for Amazon Athena, are going to be Apache Parquet and ORC and it's going to give you a huge performance improvement.
And to get your files into the Apache Parquet or ORC format, you must use a service for example, **Glue**.

Glue can be very helpful to convert your data as an _ETL_ job, between, for example, CSV and Parquet.
Now, also because we want to scan less data, we need to compress data for smaller retrievals.

So you know that Athena can query data in S3, but actually you can query data anywhere, for example, in relational or non-relational databases, you can query objects and custom data sources, would it be on AWS or on-premises.
How? Well, you use what's called a **Data Source Connector**.
It's a _Lambda Function_, and that Lambda function is going to run the Federated Queries in other services.
So that could be, for example, CloudWatch Logs, DynamoDB, RDS, and so on.
So it's very powerful.

C++ Primitive Data Types
Published: 2023-11-21 18:56:31

- Fundamental data types implemented directly by the C++ language
- Character types
- Integer types
    - signed and unsigned
- Floating-point types
- Boolean type
- Size and precision is often compiler-dependent
    - #include `<climits>`

---

### Type Sizes

- Expressed in bits
- The more bits the more values that can be represented
- The more bits the more storage required

| Size (in bits) | Representable Values |  |
| --- | --- | --- |
| 8 | 256 | 2^8 |
| 16 | 65,536 | 2^16 |
| 32 | 4,294,967,296 | 2^32 |
| 64 | 18,446,744,073,709,551,615 | 2^64 |

---

### Character Types

- Used to represent single characters, ‘A’, ‘X’, ‘@’
- Wider types are used to represent wide character sets

| Type Name | Size / Precision |
| --- | --- |
| char | Exactly one byte. At least 8 bits. |
| char16_t | At least 16 bits. |
| char32_t | At least 32 bits. |
| wchar_t | Can represent the largest available character set |

---

### Integer Types

| Type Name | Size / Precision |
| --- | --- |
| signed short int | At least 16 bits. |
| signed int | At least 16 bits. |
| signed long int | At least 32 bits. |
| signed long long int | At least 64 bits. |

| Type Name | Size / Precision |
| --- | --- |
| unsigned short int | At least 16 bits. |
| unsigned int | At least 16 bits. |
| unsigned long int | At least 32 bits. |
| unsigned long long int | At least 64 bits. |
- In addition to those shown in the table, it’s possible to store both **signed** and **unsigned** integers in the character data type
- If you want to declare a signed integer you don’t need to use the **signed** keyword, since by default integers are signed.
- Similarly, if you want an integer type that stores very large numbers, you can simply declare the type as **long long.** And you’ll get a signed long long integer.
- If you want ***unsigned*** integers, that is integers that are 0 or positive values only, then you’re required to use the ***unsigned*** keyword.
- By default, all integers are **signed**.

---

### Floating-point Type

- Used to represent non-integer numbers
- Represented by mantissa and exponent (scientific notation)
- Precision is the number of digits in the mantissa
- Precision and size are compiler dependent

| Type Name | Size / Typical Precision | Typical Range |
| --- | --- | --- |
| float | / 7 decimal digits | 1.2 x 10^-38 to 3.4 x 10^38 |
| double | No less than float / 15 decimal digits | 2.2 x 10^-308 to 1.8 x 10^308 |
| long double | No less than double/ 19 decimal digits | 3.3 x 10^-4932 to 1.2 x 10^4932 |

---

### Boolean Type

- Used to represent true and false
- Zero is false
- Non-zero is true

| Type Name | Size / Precision |
| --- | --- |
| bool | Usually 8 bits true or false  |

Difference between “𝐈𝐧𝐯𝐚𝐥𝐢𝐝𝐚𝐭𝐞 𝐂𝐚𝐜𝐡𝐞𝐬 and 𝐑𝐞𝐩𝐚𝐢𝐫 𝐈𝐃𝐄 in Android Studio”?
Tags: androidstudioerror, androidappdev, androidstudio, android
Published: 2023-11-21 17:45:26

Have you ever wondered what’s the difference between “𝐈𝐧𝐯𝐚𝐥𝐢𝐝𝐚𝐭𝐞 𝐂𝐚𝐜𝐡𝐞𝐬 and 𝐑𝐞𝐩𝐚𝐢𝐫 𝐈𝐃𝐄 in Android Studio”? 🤔


Well here’s the answer ->

- “𝐈𝐧𝐯𝐚𝐥𝐢𝐝𝐚𝐭𝐞 𝐂𝐚𝐜𝐡𝐞𝐬”:

𝐈𝐧𝐯𝐚𝐥𝐢𝐝𝐚𝐭𝐞 𝐂𝐚𝐜𝐡𝐞𝐬 is a built-in feature of Android Studio used to clear internal caches and is typically used for resolving cache related issues within the IDE.

Use 𝐈𝐧𝐯𝐚𝐥𝐢𝐝𝐚𝐭𝐞 𝐂𝐚𝐜𝐡𝐞𝐬 when you encounter issues related to project indexing, synchronization, or general IDE performance. It can help resolve various synchronization and cache related issues.

- “𝐑𝐞𝐩𝐚𝐢𝐫 𝐈𝐃𝐄”:

The 𝐑𝐞𝐩𝐚𝐢𝐫 𝐈𝐃𝐄 option is typically used when there are problems with the Android Studio installation itself and is primarily used when you suspect problems with the Android Studio installation files.

Use 𝐑𝐞𝐩𝐚𝐢𝐫 𝐈𝐃𝐄 when you suspect that Android Studio’s installation files are corrupted or incomplete, leading to IDE launch or stability problems.

Both option can be found in the 𝐅𝐢𝐥𝐞 menu in Android Studio.
Why do we NOLOCK AND LOCK in SQL server with an example
Tags: webdev, programming, database, sql
Published: 2023-11-21 17:45:02

In SQL Server, `NOLOCK` and `LOCK` are hints used in queries to control how the database engine handles locking and concurrency. These hints affect how data is read and modified in a multi-user environment. 

1. **NOLOCK**: It's also known as the `READUNCOMMITTED` isolation level. When you use `NOLOCK`, it allows a query to read data without waiting for other transactions to release locks on that data. This can improve query performance in certain scenarios because it doesn't wait for locks held by other transactions. However, it comes with the risk of reading uncommitted or "dirty" data that might be rolled back by another transaction.

Example:
```sql
SELECT * FROM TableName WITH (NOLOCK);
```

2. **LOCK**: This hint is used to acquire locks explicitly on the data being accessed, ensuring consistency and preventing other transactions from modifying it until the lock is released. There are different types of locks (`ROWLOCK`, `TABLOCK`, `XLOCK`, etc.) that can be specified depending on the granularity of the lock required.

Example:
```sql
SELECT * FROM TableName WITH (TABLOCK);
```

However, it's essential to use these hints cautiously because:

- `NOLOCK` can lead to reading inconsistent or incorrect data.
- `LOCK` hints can cause blocking and affect concurrency, potentially leading to performance issues if not used appropriately.

In many cases, it's better to rely on the default isolation levels provided by the database system to manage locking and ensure data consistency. Proper indexing, query optimization, and understanding the transaction isolation levels usually provide better long-term solutions for performance and consistency concerns.
The OpenAI Saga: the Firing of Sam Altman and Its Implications
Tags: openai, chatgpt
Published: 2023-11-21 17:44:48

In recent days, the tech world has been shaken by the dramatic events unfolding at OpenAI. Here's a speculative analysis and opinion piece on the situation, considering the facts reported by various sources like Reuters and others:

### The Facts: As Reported by Reuters

1. **Sam Altman's Firing**: According to Reuters, Sam Altman was ousted as the CEO of OpenAI due to fundamental disagreements over AI safety and development speed [(source)](https://www.reuters.com/technology/sam-altmans-firing-openai-reflects-schism-over-future-ai-development-2023-11-20/).
2. **Safety Concerns**: Ilya Sutskever, OpenAI's Chief Scientist, reportedly disagreed with Altman's approach, fearing the rapid deployment of AI could compromise safety.
3. **New Product Announcements**: Tensions escalated following OpenAI's announcement of new commercially available products, which seemed to push AI development into a more aggressive phase.

### Speculative Analysis

1. **Impact of Firing Altman**: If the core issue at OpenAI was a fear of AI advancing too fast, firing Altman might not address the underlying concerns. AI development is a global and competitive field. Altman, with his vision and expertise, could potentially join or establish another venture, continuing his approach to AI development. The pace of AI advancement won't likely slow down due to his departure from OpenAI.
   
2. **Many Believe in Sam's Vision for AI**: The reported willingness of over 700 OpenAI employees to follow Altman if he moves to Microsoft reflects a strong loyalty and belief in his vision [source](https://techcrunch.com/2023/11/20/openai-ai-talent-poaching-war/). This loyalty underscores that the ethos and direction set by Altman resonate with a significant portion of the AI community. Even drastic measures to halt this momentum would likely be futile, as AI research and development are now deeply integrated into the global tech landscape. So even if somehow Sam wasn't here to lead OAI there would be someone else leading the development and rapid progression of AI research.

3. **The Real Motive?**: What drove the board's decision to fire Altman? Was it a genuine concern for AI safety, or were there other factors at play, perhaps related to power dynamics, control over AI's future, or even personal conflicts? It's challenging to pinpoint the exact motives, but it's clear that the decision has profound implications for the future of AI. The firing might reflect a broader anxiety within the tech community about the rapid advancements in AI and the societal and ethical dilemmas they present.

### Closing Thoughts

The events at OpenAI serve as a microcosm of the larger debates surrounding AI: its pace, its governance, and the balance between innovation and safety. While the future remains uncertain, one thing is clear – AI development is a juggernaut that cannot be slowed or controlled, even if people are worried or scared.

Variables in C++
Published: 2023-11-21 16:56:02

- If we had to program using the specific memory locations of a Random Memory Access (RAM), it wouldn’t be a lot of fun, and we’d likely have a lot of programmer errors.
- A variable is an abstraction for a memory location
- Allow programmers to use meaningful names and not memory addresses
- Variables have
    - Type - their category (integer, real number, string, Person, Account…)
    - Value - the contents (10, 3.14, “Tim”…)
- Variables **must** be declared before they are used
- A variables value may change

```cpp
age = 22;        // Compiler error
```

```cpp
int age;

age = 22;
```

---

### Declaring Variables

<aside>
💡 VariableType VariableName

</aside>

```cpp
int age;
double rate;
string name;

Account franks_account;
Person james;
```

---

### Naming Variables

- Can contain letters, numbers, and underscores
- Must begin with a letter or underscore (_)
    - cannot begin with a number
- Cannot use C++ reserved keywords
- Cannot redeclare a name in the same scope
    - C++ is case sensitive

| Legal | Illegal |
| --- | --- |
| Age | int |
| age | $age |
| _age | 2022_age |
| My_age | My age |
| your_age_in_2000 | Age+1 |

---

### Style and Best Practices

- Be consistent with your naming conventions
    - myVariableName vs my_variable_name
    - avoid beginning names with underscores
- Use meaningful names
    - not too long and not too short
- Never use variables before initializing them
- Declare variables close to when you need them in your code

---

### Initializing Variables

```cpp
int age;      // uninitialized

int age = 22; // C-like initialization

int age (22); // Constructor initialization

int age {22}; // C++11 list initialization syntax
```

---

### Global Variables

- Variables declared within the curly braces of the main function are called Local Variables because their scope or visibility is limited to the statements in the main function that follow the declaration of the variable. This is generally what you want to do.
- However, sometimes you see variables declared outside of a function, these variables are called Global Variables and they can be accessed from any part of your program.
- Unlike local variables, global variables are automatically initialized to zero.
- Since global variables can be accessed by any part of the program, this means they can potentially be changed from any part of the program. This can make finding errors and debugging more difficult.
How scroll to specific element with Vue.js 3
Tags: vue, vue3, typescript, javascript
Published: 2023-11-21 16:36:52

Sometimes, we need to make a scroll go to specific section/element of our page. Achieving this with Vue is very simple; you just need to use a **[template ref](https://vuejs.org/guide/essentials/template-refs.html)** for that. Let's see how to do it.

1 - Create a component template and give it a `ref` attribute:

```js
<template>
 <main>
   <section ref="sectionRefEl">
     <some-component>element</some-component>
   </section>
 </main>
</template>
```

2 - Create the `script` section and declare your `ref` inside it:

```js
<script setup lang="ts">
import { ref } from 'vue'

// Here is our template ref typed as HTMLElement or null
const sectionRefEl = ref<HTMLElement | null>(null)
</script>
```

3 - Create a function that make the scroll happen:

```js
<script setup lang="ts">
import { ref } from 'vue'

// Here's our template ref typed as HTMLElement or null
const sectionRefEl = ref<HTMLElement | null>(null)

// Using scrollIntoView() function to achieve the scrolling
function scrollTo(view: Ref<HTMLElement | null>) { 
  view.value?.scrollIntoView({ behavior: 'smooth' }) 
}
</script>
```

The `scrollTo` function accepts a `ref` parameter and enables scrolling by using the `DOM API` function `scrollIntoView()`.

> Read more about the [scrollIntoView()](**https://developer.mozilla.org/pt-BR/docs/Web/API/Element/scrollIntoView**) function to learn more.



4 - Now you just need to call your function anywhere you want, passing a `ref` as param and see the scroll happening.

For example, you can create a button firing the method:

```js
<template>
 <main>
   <section ref="sectionRefEl">
     <some-component>element</some-component>
   </section>
   <button @click="scrollTo(sectionRefEl)">Scroll to</button>
 </main>
</template>
```

And that's it!
