DeepSeek R1 First Impressions

DeepSeek R1 is almost as good as me at belabored exhaustive analysis and application of C89 rules. For practical purposes, it's equally good.

I asked: "How would you implement zig-zag encoding in strictly portable C89?" It was spitting out thinking output for at least a minute, but it got a basically-perfect solution on first try:

unsigned int zigzag_encode(int n) { return (((unsigned int)n << 1) ^ ((n < 0) ? -1 : 0); }

It also provided a `zigzag_encode_long`.

Note that this code will optimize on modern C compilers to the best assembly you could write. There is no branch in the produced code with even just `-O1` (`clang`, `gcc`), the branch is how we portably tell the compiler the right idea.

The only thing DeepSeek did "wrong" vs the above, was redundantly add an `(unsigned int)` cast to the `-1`. I mentioned this as I would to a person: that the usual arithmetic conversions would take care of it at the `^`. It reasoned the rest on its own: yes, because the left operand is already at least an unsigned int, so integer promotion will make the left side an unsigned int as well.

We talked at length about how we can prove that the above is portable to the most pathological C89-conformant implementations. It kept taking longer to "think", but it didn't show any weakness until the very last question.

I asked it to help me rigorously prove if the maximum value of unsigned integers is required by the C standard to be a Mersenne number (2^n-1). To have all bits one, that is.

What if an implementation just decided to arbitrarily not use one or more of the top values? I.e., why not `#define UINT_MAX 0xFFFFFFFE`?

DeepSeek R1 didn't seem to conceive of this possibility until I made it explicit. (But it did a great job of ruling out all others.)

Finally, it gave a longer, non-trivial argument, which I don't find convincing. Basically, it seemed to be saying that since integers used "pure binary representation", and every value bit could be either one or zero, well then the maximum value always has all value bits one - in other words, it seemingly assumed that just because each value bit individually was allowed to be one or zero, the possibility of them all being one at once must be both legal and used to represent a distinct value.

I see a shorter argument, which follows directly from what the standard does say: C89 has two definitions of `~`:

flip all the bits;

subtract from maximum value of that unsigned integer type.

The only way both can be true at once is if the maximum value is all value bits one. DeepSeek R1 agreed.

So what does this all mean?

This is an insane level of competence in an extremely niche field. Less than a year ago I tested LLAMA on this, and LLAMA and I didn't even get past me hand-holding it through several portability caveats. DeepSeek R1 and I just had a full-blown conversation that most devs I've talked to couldn't have with me. DeepSeek R1 managed to help me think in an extremely niche area where I'm basically a world-class expert (since the area in question is C89 portability, "world-class expert" is derogatory, but still).

If it's this good in one domain, it's this good in most domains. I bet it can do comparably well in Python, Go, JavaScript, C++, and so on.

In other words, it's already better than many devs in areas like this. I've seen plenty of devs making 6-figure USD salaries who didn't bother to know any of their day job tech stack this deeply. There's a market adjustment coming. Knowledge and expertise are about to become dirt-cheap commodities.

AI will eat current software dev jobs even faster than even I thought - and I already thought it would be sooner than most expect. Meanwhile, much of the industry is busy rationalizing from human intuition and ignorance that it just can't happen.

For years I've thought that the future is human devs delegating to teams of AI. That future is almost upon us, and this AI is good enough that I will be seriously experimenting with making that future a reality. I think if you hack together the right script to hook it up to a sandbox with dev tools, and prompt it just right... you might already be able to get this thing to actually do useful dev work.

<!DOCTYPE html>

<html>

<head>

    <title>My First Web Page</title>

    <link rel="stylesheet" type="text/css" href="styles.css">

</head>

<body>

    <h1>Welcome to My Web Page</h1>

    <p>This is a paragraph of text on my web page.</p>

</body>

</html>

: Declares the document type and HTML version.

: The root element of an HTML page.

: Contains meta-information about the document.

: Connects the HTML to an external CSS file.

: Contains the content of the web page.

Essential HTML Tags

HTML uses various tags to define different parts of a web page:

to : Headings of different levels.

: Paragraph of text.

: Anchor tag for hyperlinks.

: Embeds images.

: Defines divisions or sections.

: Inline container for text.

Creating Your First HTML Page

Follow these steps to create a simple HTML page:

Open your text editor.

Write the basic HTML structure as shown above.

Add a heading with the tag.

Add a paragraph with the tag.

Save the file with a .html extension (e.g., index.html).

Open the file in your web browser to view your web page.

Introduction to CSS

CSS is used to style and layout HTML elements. It can be included within the HTML file using the <style> tag or in a separate .css file linked with the <link> tag.

Basic CSS Syntax

CSS consists of selectors and declarations. Here’s an example:

css

Copy code

h1 {

    color: blue;

    font-size: 24px;

}

Selector (h1): Specifies the HTML element to be styled.

Declaration Block: Contains one or more declarations, each consisting of a property and a value.

Styling HTML with CSS

To style your HTML elements, you can use different selectors:

Element Selector: Styles all instances of an element.

Class Selector: Styles elements with a specific class.

ID Selector: Styles a single element with a specific ID.

Example:

html

Copy code

<!DOCTYPE html>

<html>

<head>

    <title>Styled Page</title>

    <link rel="stylesheet" type="text/css" href="styles.css">

</head>

<body>

    <h1 class="main-heading">Hello, World!</h1>

    <p id="intro">This is an introduction paragraph.</p>

</body>

</html>

In the styles.css file:

css

Copy code

.main-heading {

    color: green;

    text-align: center;

}

#intro {

    font-size: 18px;

    color: grey;

}

CSS Layout Techniques

CSS provides several layout techniques to design complex web pages:

Box Model: Defines the structure of an element’s content, padding, border, and margin.

Flexbox: A layout model for arranging items within a container, making it easier to design flexible responsive layouts.

Grid Layout: A two-dimensional layout system for more complex layouts.

Example of Flexbox:

css

Copy code

.container {

    display: flex;

    justify-content: space-around;

}

.item {

    width: 100px;

    height: 100px;

    background-color: lightblue;

}

Best Practices for Writing HTML and CSS

Semantic HTML: Use HTML tags that describe their meaning clearly (e.g., , , ).

Clean Code: Indent nested elements and use comments for better readability.

Validation: Use tools like the W3C Markup Validation Service to ensure your HTML and CSS are error-free and standards-compliant.

Python Day 5

Today we warm up by completing Exercise 25. This is even more practice with functions and variables!

To run the program we call python in the terminal and import ex25 from there.

As I was working through calling the different functions in the terminal I realized that I missed a function - specifically the one that sorted a sentence. I called it and ended up getting a mess of individual letters. After bug hunting I found the issue to be that I called sort_words(sentence) instead of sort_words(words)

After fixing those issues I finished running through the function calls in the terminal and it went great!

Up next is Exercise 26! We are halfway through the book and it is time for a test. We are given broken code that we copy paste into a file. Our job is to fix it and get the program running! As I went through the program I left comments wherever I was fixing code. Below is my finished and fixed program.

And here is the output in the terminal:

Exercise 27 went over different booleans as well as a chart to memorize. The next practical was exercise 28 where you type in different statements then guess if they will be true or false. With my previous experience in programming I already knew a lot - the only thing that tripped me up was NOT OR booleans. Here's the output of the terminal!

Chugging right along to Exercise 29! ex29 introduced if statements. I already know lots about if statements from Javascript so this is more of a refresher than anything.

And then the output:

Exercise 30 introduces Else If statements.

And the output:

Exercise 31 combines everything that we've learned about If/Elif statements with the new concept of Nested statements. Using nested statements we are able to write a very simple Choose Your Own Adventure text game.

Here are a couple different runs I did with this program. My first try was not the best - I ended up having my mind turned into Jello!

My second run went better! I ran into a bear but I survived.

For the study drill it challenged me to write my own text game. I made a very simple one and got about halfway through where I want it to be.

That's it for today folks!

Navigating the Mobile-First Indexing Revolution in 2023: You’re Definitive Guide

The digital landscape is an ever-evolving realm, and in 2023, one thing is abundantly clear – mobile is king. With the advent of Mobile-First Indexing, the way websites are ranked by search engines has undergone a profound transformation. In this comprehensive guide, we'll explore the Mobile-First Indexing landscape, provide you with a "mobile-first indexing checklist," delve into "mobile SEO best practices," and uncover the critical "mobile ranking factors." Along the way, we'll add a dash of human touch to help you truly grasp the significance of this seismic shift.

The Mobile-First Indexing Revolution

What is Mobile-First Indexing?

Mobile-First Indexing is Google's response to the mobile-centric digital age. Traditionally, Google primarily crawled and indexed desktop versions of websites, using that data to determine rankings for both desktop and mobile searches. However, the rise of mobile usage led to a fundamental change – Google began prioritizing the mobile version of a website for indexing and ranking. This means that a website's mobile version now takes precedence in search results, making mobile optimization more critical than ever.

Why Does Mobile-First Indexing Matter?

Mobile-First Indexing matters for several compelling reasons:

User-Centric Approach: It aligns with the user-centric trend, as more people access the internet via mobile devices than ever before.

Improved User Experience: Mobile-First Indexing encourages website owners to enhance the mobile experience, resulting in faster-loading pages and improved usability.

Better Rankings: Websites that perform well on mobile devices are more likely to rank higher in search results, increasing organic traffic.

Mobile-First Indexing Checklist

Embarking on a Mobile-First Indexing journey requires a meticulous approach. Here's a checklist to help you navigate this transformative process:

1. Mobile-Friendly Design:

Ensure your website employs a responsive design that adapts seamlessly to various screen sizes, from smartphones to tablets.

2. Speed Matters:

Optimize your site's loading speed on mobile devices. Compress images, minify CSS and JavaScript, and leverage browser caching to reduce load times.

3. Mobile SEO Best Practices:

Implement on-page SEO techniques tailored for mobile devices, including optimizing title tags, meta descriptions, and headers for mobile users.

4. Mobile Content:

Make sure your mobile site contains the same valuable content as the desktop version, including text, images, videos, and infographics.

5. Structured Data:

Use schema markup to provide search engines with structured data, helping them understand your content and display rich snippets.

6. Test on Mobile Devices:

Regularly test your website's performance on various mobile devices and browsers to identify and rectify any issues promptly.

7. Mobile Sitemaps:

Create and submit a mobile sitemap to Google Search Console to ensure all mobile pages are indexed correctly.

8. Optimize for Local Search:

If you have a physical location, optimize your site for local search, ensuring mobile users can easily find your business.

9. Monitor Mobile Usability:

Keep a close eye on Google Search Console for mobile usability issues and resolve them promptly.

Mobile SEO Best Practices

To excel in the era of Mobile-First Indexing, you need to embrace these Mobile SEO best practices:

1. Mobile-Responsive Design:

Invest in a mobile-responsive design that automatically adjusts to different screen sizes. This ensures a consistent user experience across devices.

2. AMP (Accelerated Mobile Pages):

Consider implementing Accelerated Mobile Pages to create faster-loading, streamlined versions of your content, ideal for mobile users.

3. Optimize Images:

Compress and optimize images for mobile devices to reduce page load times without compromising quality.

4. Mobile-Friendly Navigation:

Simplify navigation menus and use mobile-friendly navigation elements, such as hamburger menus, to enhance user experience.

5. Local SEO Optimization:

If you have a physical business presence, optimize your website for local search by including location-specific keywords and information.

6. Voice Search Optimization:

As voice search becomes more prevalent, optimize your content for natural language queries and long-tail keywords.

7. User Experience Matters:

Prioritize a seamless user experience on mobile devices. Ensure that buttons are easily clickable, fonts are legible, and pop-ups are minimal.

Critical Mobile Ranking Factors

Understanding the key factors that influence mobile rankings is essential. Here are some critical mobile ranking factors to consider:

1. Page Speed:

Fast-loading pages are paramount. Google prioritizes websites that load quickly on mobile devices to improve user experience.

2. Mobile-Friendly Design:

Websites with responsive designs that adapt to different screen sizes are favored by search engines.

3. Mobile Usability:

User-friendly mobile experiences, including easy navigation and legible text, contribute to better rankings.

4. Quality Content:

High-quality, relevant content that satisfies user intent is crucial for mobile rankings.

5. Mobile-Friendly Pop-Ups:

Avoid intrusive pop-ups that can disrupt the user experience on mobile devices.

6. Mobile Crawlability:

Ensure that Googlebot can crawl your mobile website without issues, including access to CSS and JavaScript files.

7. Mobile Interstitials:

Limit the use of interstitials or pop-ups that cover the main content, as these can negatively impact rankings.

As we delve into the intricacies of Mobile-First Indexing, it's vital to remember that behind the algorithms and data points are real people – your audience. The shift towards mobile-centric indexing is driven by the evolving habits and preferences of users who rely on mobile devices for information, entertainment, and connection.

Imagine a user on a busy morning commute, searching for a nearby coffee shop to grab a quick cup of joe. Your website, optimized for Mobile-First Indexing, loads swiftly, provides clear directions, and displays enticing images of steaming coffee cups. In this scenario, Mobile-First Indexing isn't just an algorithmic change; it's an opportunity to connect with users when they need you the most.

In 2023, your website's success hinges on its mobile performance. By following the Mobile-First Indexing checklist, embracing Mobile SEO best practices, and understanding the critical mobile ranking factors, you can position your site at the forefront of the mobile revolution. It's not just about appeasing algorithms; it's about delivering an exceptional mobile experience to the people who matter most – your audience. So, get ready to conquer Mobile-First Indexing, and let your website shine in the mobile spotlight!
