### <a name="introduction"></a>1. Introduction

While updates are commonplace in database operations, they're not always necessary. When you only want to perform updates under specific conditions, what do you do? Find the answer in this article.

### <a name="basic-update"></a>2. Basic UPDATE Syntax

Let's start with a typical example of the UPDATE statement.

```sql
UPDATE employees
SET salary = 50000
WHERE department_id = 10;
```

This query sets the salary of all employees in department 10 to 50,000.

### <a name="conditional-update"></a>3. Updating Only When Changes Occur

But what if you want to update only when the new salary is different from the current one?

```sql
UPDATE employees
SET salary = new_salary
WHERE salary != new_salary AND department_id = 10;
```

This query targets only the employees in department 10 whose current salary differs from the new one.

### <a name="example"></a>4. Practical Example

Consider the following data:

| id | name  | salary | department_id |
|----|-------|--------|---------------|
| 1  | Alice | 40000  | 10            |
| 2  | Bob   | 50000  | 10            |

If the new salary is 50,000, the above query will update only Bob's record.

### <a name="conclusion"></a>5. Conclusion

Updating only when changes occur is a great way to cut down on needless operations and increase the efficiency of your database. Mastering this technique enables more sophisticated database handling.

Time Management Techniques for Developers: 10 Tips to Boost Productivity
Tags: webdev, javascript, beginners, programming
Published: 2023-08-08 14:14:38


As programmers, we often find ourselves juggling multiple tasks, tight deadlines, and ever-changing requirements. Time management is a crucial skill that can significantly impact our productivity and overall well-being. In this blog, we'll explore ten effective time management strategies tailored specifically for developers, so you can optimize your workflow, reduce stress, and achieve more in less time.

1.Prioritize Your Tasks:
Start each day by identifying the most important tasks you need to accomplish. Use the Eisenhower Matrix (urgent vs. important) to prioritize your work and focus on high-priority tasks that align with your goals.

2.Utilize the Pomodoro Technique:
The Pomodoro Technique involves breaking your work into focused intervals (e.g., 25 minutes) followed by short breaks. Use a timer to maintain concentration during work sessions and to recharge during breaks.

3.Time Blocking:
Divide your day into blocks of time dedicated to specific tasks or projects. Time blocking helps maintain focus, prevents multitasking, and ensures you allocate sufficient time for each task.

4.Set Realistic Goals:
Set achievable goals for each day, week, and month. Break down larger projects into smaller, manageable tasks, and celebrate your accomplishments to stay motivated.

5.Use Task Management Tools:
Leverage task management tools like Trello, Asana, or Notion to keep track of your to-do lists, deadlines, and progress. These tools can help you stay organized and collaborate effectively with your team.

6.Learn Keyboard Shortcuts:
Mastering keyboard shortcuts in your code editor and other tools can save you significant time and reduce reliance on the mouse.

7.Regular Breaks and Physical Activity:
Take short breaks throughout the day to rest your mind and eyes. Engage in physical activities like stretching or going for a walk to boost energy and creativity.

8.Version Control Best Practices:
Follow best practices for version control using Git. Proper branching and commit messages can save time and simplify collaboration with your team

9.Limit Distractions:
Identify common distractions and take steps to minimize them. Consider using website blockers or setting designated "focus time" to avoid interruptions.

10.Reflect and Improve:
Regularly assess your time management techniques and make adjustments as needed. Continuous improvement is key to refining your workflow and maximizing productivity.

The year I was born, 1979, The Fonz from the Happy Days TV show, gives Ritchie a strategy to apply to consulting. This gets harder as I get older because I’ve seen the same problems so many times the longer I work in my career. I get so excited to help quickly (after 2 weeks) and this is usually what you **shouldn’t do**.

If you’re in a hurry, skip to 2:09

{% youtube BNTMb7Qqees %}

Consultants in software have a particularly bad reputation because the consequences of their decisions (good and bad) are often dealt with by employees months to years after the consultants are gone. This can create the belief that the consultants think they were successful, while the employees feel like the consultants made things worse, and this in turn makes them dismissive of any future consultants or contractors. The employees think why should they listen to consultants when the consultants make bad decisions and then can’t learn from their mistakes?

I’ve seen fellow consultants use this strategy to quickly garner respect, and others not use this strategy, myself included, and either be ignored, get miserable on their gig that they’re not living up to their perceived potential, or both.

Yes, some clients are beyond saving. Some people are just miserable or not self-aware and you’re better off moving onto a new project. However, we’re in consulting because we _want_ to try despite being aware it may not work.

Be a team player by helping on bugs, support their causes to management, and take accountability for mistakes even if the mistakes aren’t yours. Let them know you support them, will do the hard work, and will defend them. Once you’re not a threat, but instead a boon, they’ll support your suggestions to management or them because they know it’s in _both_ of your best interests.

If you’re interested in helping other consultants like yourself, key leadership lessons in video to watch:

- intentionally asking you fellow consultant how things are going; many people want someone to listen
- being blunt and not sugar coating the situation
- helping them empathize with other’s situations to change their perspective
- indicating an opportunity if they can’t see it
- encouragement while honest believing in their future greatness
Beginning Coder Challenges
Tags: beginners, codenewbie
Published: 2023-08-08 13:57:06

When I first started coding I thought there was no way I could learn how to code. I thought that this wasn't the right path for me, I thought that it was too hard, I simply just thought that I couldn't do it. Fast forward six months later and I'm creating full stack applications by myself. So I figured I would write a blog on some challenges that beginners face and how to overcome them. 

First and foremost you will experience the  imposter syndrome. I really think that is the hardest to get rid of. I still have imposter syndrome to this day. I have talked to my coder friends who have amazing jobs and they still have imposter syndrome. One thing my friend said to me to really help me get over it is the fact that once you started you're meant to be there. At the beginning you will really have imposter syndrome and it takes some time to settle down but it will eventually. Just make sure you show up and code a little bit everyday. Be patient with yourself. You are learning a whole new language this is not an easy skill. Coding is essentially like any other skill. Once you put the reps in the easier it comes. So just make sure to code a little bit every day. 

Make sure you really understand what you're doing and why. When I first started coding I really didn't understand what I was coding or even why I was. Really make sure you take the time to understand the functionality of what you're doing and why you are doing it. This will really help solidify concepts in your brain and just make the learning process overall easier. Also note that coding is ongoing. You are always going to be learning. This isn't a once you know it you know everything. I realized that this is a skill that you will be learning for years upon years. I used to get so overwhelmed by all of the information coming at me at once and I was trying to learn it all so fast. Just take your time and know that this is a process. You will fall get demotivated but you just have to get back up.

Another challenge is understanding that you don't know what you don't know at the beginning. Let me explain. To clarify, you simply won't understand topics or functionality at the beginning and then you won't know what the topics or functionality are. You feel simply lost floating in space. Just know that with time and practice things will start to click. Coding is definitely a hands on learning experience. Of course you can read and watch all the videos in the world about coding but the best way to learn is to simply start coding. At the beginning I was reading and watching so many videos but when it came time for me to do the coding I was lost. The best way to learn in my opinion is to actually get on the keyboard and start writing some code. 

Learning to code is definitely not for the week. There is a lot of trial and error involved. You will get upset and want to quit sometimes or just think its not for you but that's not the case, just make sure you stay with it. Once you're writing full stack applications you will be happy that you didn't quit. Just make sure to get your reps in and stick with it.
Python 參數中的 '/' 與 '*'
Tags: python
Published: 2023-08-08 13:53:58

在查看一些 Python 文件時常會看到參數中出現 `/` 與 `*`, 一開始沒有太注意, 後來才發現原來是有意義的, 簡單的來說：

- `/`：表示出現在它前面的參數只能是以對應位置傳入資料, 不能用指名的方式。
- `*`：表示出現在它之後的參數只能用指名的方式傳入資料。

這樣講可能有點抽象, 以底下這個函式為例：

```python
>>> def foo(n, /, a, b=2, *, c):
...     print(f'{n=}')
...     print(f'{a=}')
...     print(f'{b=}')
...     print(f'{c=}')
```

救代表：

- `n` 必須是位置引數
- `a` 可以是位置引數或是指名引數
- `b` 可以是位置引數或是指名引數
- `c` 必須是指名引數

在叫用 `foo` 的時候就必須要符合以上規定, 以下都是不符合規定的狀況：

```python
>>> foo(n=10)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: foo() got some positional-only arguments passed as keyword arguments: 'n'
```

由於 `n` 只能以位置參數傳入資料, 所以錯誤訊息明白告訴你把只能依照位置傳入的引數當指名引數用了。

```python
>>> foo(10, 20)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: foo() missing 1 required keyword-only argument: 'c'
```

這樣 `n` 是 10, `a` 是 20, `b` 是預設的 2, 但是 `c` 沒有值, 所以也不行。

```python
>>> foo(10, 20, 30)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: foo() missing 1 required keyword-only argument: 'c'
```

由於 `c` 必須以指名方式傳入資料, 所以即使多加了一項資料, 也不符合規定。

```python
>>> foo(10, 20, c=30)
n=10
a=20
b=2
c=30
```

這樣就對了。注意到由於以位置傳資料的引數必須出現在定名稱傳資料的參數之前, 所以也不能這樣叫用：

```python
>>> foo(10, a=20, 25, c=30)
```

否則 `b` 變成是以位置傳入資料, 但是卻又出現在指名傳資料的 `a` 後面了。

你自己不一定會這樣設定參數, 但是許多套件內的模組為了傳遞資料的彈性, 又必須讓你知道傳遞資料時的規範, 都會使用這樣的方式設定參數, 瞭解它們的意義才能看懂文件, 運用正確的方式叫用函式或方法。
Comment utiliser la propriété filter en css
Published: 2023-08-08 13:53:38

Tout d'abord voici la définition que nous propose MDN:

> La propriété CSS `filter` permet d'appliquer des filtres et d'obtenir des effets graphiques de flou, de saturation, etc. Les filtres sont généralement utilisés pour ajuster le rendu d'une image, d'un arrière-plan ou des bordures.


Développement:
Pour utiliser la propriété CSS filter, on utilisera none ou une ou plusieurs des fonctions listées ci-après avec, pour chacune, un argument. Si la valeur est invalide, la fonction renverra none. Sauf mention contraire, les fonctions qui acceptent des valeurs exprimées en pourcentages (34%) acceptent également des valeurs décimales (0.34).

Lorsqu'une seule propriété filter possède deux fonctions (ou plus), le résultat obtenu sera différent de l'application de deux propriétés filter (ou plus) séparées avec chacune une fonction. 

Quelques valeur du filter css:
La propriété de Filtre CSS filter permet de spécifier une/des fonctions de Filtre CSS qui correspondront au divers effets à appliquer sur un élément HTML. Exemple de syntaxe CSS filter : filter : contrast(400%); filter : grayscale(0.5) blur(10px); filter : sepia(20%) opacity(10%) drop-shadow(20px 20px 20px #000);

Is It Dyslexia? What should you do?
Published: 2023-08-08 13:50:29

Dyslexia is a neurological condition that affects reading, writing, spelling, and sometimes speaking abilities. It is not related to intelligence or cognitive ability, but rather it is a specific learning difference that impacts the way the brain processes written language. Dyslexia is considered a lifelong condition, but with the right support and interventions, individuals with dyslexia can learn to read and write effectively.

Key characteristics of dyslexia include:

Difficulties in Reading: People with dyslexia often struggle with recognizing and understanding words. They might have difficulty with letter-sound associations, reading fluency, and accurately processing words.

Spelling Challenges: Spelling can be challenging for individuals with dyslexia due to difficulties with phonological awareness and remembering the order of letters in words.

Phonological Processing Issues: Phonological processing involves recognizing and manipulating sounds in spoken language. People with dyslexia may struggle with phonemic awareness, which can affect their ability to decode words.

Difficulty with Sequencing: Ordering and sequencing information, such as numbers or letters, can be challenging for individuals with dyslexia.

Letter and Word Reversals: Reversing letters or words (e.g., "b" instead of "d" or "was" instead of "saw") is a common occurrence in individuals with dyslexia.

Slow Reading Speed: People with dyslexia often read more slowly than their peers due to the extra effort required to decode words.

Working Memory Challenges: Working memory, which is important for holding and manipulating information, can be impacted in individuals with dyslexia.

It's important to note that dyslexia is a spectrum, and its severity can vary from person to person. Early identification and intervention are crucial to provide appropriate support to individuals with dyslexia. Strategies and interventions might include multisensory teaching methods, explicit phonics instruction, assistive technology, speech therapy, and individualized educational plans.

Dyslexia is a recognized learning disability, and many educational systems and institutions offer accommodations and support to individuals with dyslexia to help them succeed academically and in other areas of life. If you suspect you or someone you know may have dyslexia, seeking a professional assessment by a qualified educational psychologist or learning specialist is highly recommended.
