Just the hum of the solar inverter and the click of the mechanical keyboard. I spent fifteen years building &#8220;scalable solutions&#8221; for companies that didn&#8217;t have a problem to scale. I wrote code that lived in the &#8220;cloud,&#8221; which is just a fancy word for someone else\u2019s basement. Now, I write code to manage my irrigation and track the soil pH in the north pasture. <\/p>\n<p>I saw a repo yesterday. A &#8220;modern&#8221; Python project.

A way to help the IDE help you. But the &#8220;modern&#8221; developer has turned them into a religion. They\u2019ve turned Python into a worse version of Java. Look at that <code>Generic[T]<\/code> and <code>Protocol<\/code> nonsense. Why? Are you planning on swapping out your coordinate system for a 4D hypercube next week? No. You\u2019re fetching a latitude and a longitude. They are floats. They will always be floats.<\/p>\n<p>Python is a dynamic language. That is its strength. When you clutter the screen with <code>Union[Optional[List[Dict[str, Any]]], None]<\/code>, you aren&#8217;t making the code safer; you\u2019re making it unreadable. You\u2019re forcing the reader to parse a wall of syntax before they can even see the logic. <\/p>\n<p>The &#8220;python best&#8221; way to handle types is to use them where they clarify, not where they perform. If a function takes a <code>user_id<\/code>, I know it\u2019s an integer or a string. I don&#8217;t need a <code>NewType<\/code> wrapper to tell me that. You\u2019re adding cognitive load for zero runtime benefit. Python\u2019s type hints are ignored by the interpreter anyway. You\u2019re writing a novel that the computer doesn&#8217;t even read.<\/p>\n<p>Let\u2019s look at the first terminal log.

It probably has <code>pandas<\/code> for no reason, <code>pydantic<\/code> for &#8220;validation&#8221; of two fields, and <code>request-promise-whatever<\/code> because the dev forgot how <code>urllib<\/code> works.<\/p>\n<p>In the Valley, we used to joke that a project\u2019s complexity is proportional to the size of its <code>node_modules<\/code> or its <code>site-packages<\/code>. It\u2019s not a joke anymore. It\u2019s a pathology. Every dependency you add is a security hole, a maintenance burden, and a potential breaking change. <\/p>\n<p>You don&#8217;t need a framework to make an HTTP request. You don&#8217;t need a library to parse a config file. Python\u2019s standard library is massive. Use it. <\/p>\n<p>I switched from <code>pip<\/code> to <code>uv<\/code> recently. Not because I like new tools, but because it\u2019s written in Rust and it\u2019s fast enough to keep up with my train of thought. But even with a fast tool, your <code>pyproject.toml<\/code> should be lean. <\/p>\n<pre class=\"codehilite\"><code class=\"language-bash\">silas@thinkpad:~\/farm_ops$ cat pyproject.toml\n[project]\nname = &quot;farm-weather&quot;\nversion = &quot;0.1.0&quot;\ndependencies = [\n    &quot;httpx&quot;,\n]\n\n[tool.ruff]\ntarget-version = &quot;py312&quot;\nline-length = 80\n<\/code><\/pre>\n<p>That\u2019s it.

I know that in CPython, a dictionary is a compact hash table. I know that since Python 3.6, they preserve insertion order. I know that looking up a key is O(1). When you wrap a dictionary in a Pydantic model, you\u2019re adding layers of <code>__getattr__<\/code> and <code>__setattr__<\/code> calls that slow everything down. For what? A &#8220;validation error&#8221; that you\u2019re just going to log and ignore?<\/p>\n<hr \/>\n<h2><span class=\"ez-toc-section\" id=\"The_Asyncio_Cargo_Cult\"><\/span>The Asyncio Cargo Cult<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Look at the <code>asyncio.run(main())<\/code> in the snippet. This is a CRUD app. It\u2019s doing one thing. Why is it async? <\/p>\n<p>&#8220;But Silas, it\u2019s non-blocking!&#8221; <\/p>\n<p>Shut up. You\u2019re running it on a single-core VPS or a Lambda function. You aren&#8217;t handling 10,000 concurrent connections. You\u2019re fetching one JSON blob. By making it async, you\u2019ve just made the stack traces unreadable and the debugging twice as hard. <\/p>\n<p>Asyncio is for high-concurrency network servers. It is not a &#8220;go fast&#8221; button for your script. In fact, for most CPU-bound tasks, it\u2019s slower because of the event loop overhead. And don&#8217;t get me started on the GIL (Global Interpreter Lock). Most of these kids don&#8217;t even know what the GIL is. They think <code>async<\/code> means &#8220;parallel.&#8221; It doesn&#8217;t. You\u2019re still on one thread, buddy. You\u2019re just jumping between tasks like a caffeinated squirrel.<\/p>\n<p>If you want parallelism, use <code>multiprocessing<\/code>. If you want to fetch five URLs, use a <code>ThreadPoolExecutor<\/code>. It\u2019s built-in. It\u2019s stable. It doesn&#8217;t require you to rewrite your entire codebase with <code>await<\/code> keywords like a stuttering robot.<\/p>\n<hr \/>\n<h2><span class=\"ez-toc-section\" id=\"Classes_are_Overrated_and_Memory_is_Finite\"><\/span>Classes are Overrated (and Memory is Finite)<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The <code>WeatherResponse<\/code> dataclass in the snippet.

That dictionary takes up memory. If you\u2019re processing a million weather records on a solar-powered ThinkPad, that memory matters. <\/p>\n<p>If you absolutely <em>must<\/em> use a class, use <code>__slots__<\/code>. <\/p>\n<pre class=\"codehilite\"><code class=\"language-python\">class WeatherRecord:\n    __slots__ = (&quot;temp&quot;, &quot;unit&quot;, &quot;timestamp&quot;)\n    def __init__(self, temp, unit, timestamp):\n        self.temp = temp\n        self.unit = unit\n        self.timestamp = timestamp\n<\/code><\/pre>\n<p>By defining <code>__slots__<\/code>, you tell Python not to create a <code>__dict__<\/code> for every instance. You\u2019re pre-allocating space for the attributes. It\u2019s faster and it uses a fraction of the RAM. But even better? Use a <code>namedtuple<\/code>. Or just a tuple. <\/p>\n<p>Modern developers are terrified of raw data. They want to wrap everything in an object. They want <code>weather.get_temperature_display()<\/code>. Just print the float, you coward. <\/p>\n<p>Let\u2019s look at the memory difference.<\/p>\n<pre class=\"codehilite\"><code class=\"language-bash\">silas@thinkpad:~\/farm_ops$ python3.12 -c &quot;\nimport sys\nclass Normal:\n    def __init__(self, a, b): self.a, self.b = a, b\nclass Slotted:\n    __slots__ = ('a', 'b')\n    def __init__(self, a, b): self.a, self.b = a, b\nprint(f'Normal: {sys.getsizeof(Normal(1, 2)) + sys.getsizeof(vars(Normal(1, 2)))} bytes')\nprint(f'Slotted: {sys.getsizeof(Slotted(1, 2))} bytes')\n&quot;\nNormal: 152 bytes\nSlotted: 48 bytes\n<\/code><\/pre>\n<p>A 3x reduction in memory just by being intentional.

Why? Because some book on Design Patterns told them that &#8220;Managers&#8221; are how you organize code. <\/p>\n<p>A &#8220;Manager&#8221; is usually just a collection of functions that share some state. In this case, the <code>api_key<\/code>.

You know what\u2019s more evil? Passing a <code>Config<\/code> object through fifteen layers of abstraction just to reach a function that needs a single string.

They think Python is magic. They think the &#8220;Cloud&#8221; is an infinite resource. <\/p>\n<p>It\u2019s not. <\/p>\n<p>Python is a wrapper around C. When you create a list, you\u2019re allocating a contiguous block of memory for pointers. When you append to that list and it exceeds its capacity, Python has to allocate a new, larger block and copy everything over. If you knew that, you\u2019d pre-allocate your lists. <\/p>\n<p>When you use a dictionary, you\u2019re using a hash table. If your keys have bad hash functions, you get collisions.

Why? Because it\u2019s not loading <code>asyncio<\/code>, <code>abc<\/code>, <code>dataclasses<\/code>, and <code>typing<\/code>. It\u2019s not setting up an event loop. It\u2019s just doing the work. <\/p>\n<p>In the Valley, they\u2019d say 0.4 seconds is &#8220;fast enough.&#8221; Out here, when the sun is going down and the battery on the solar array is at 10%, every millisecond of CPU time is a millisecond of light I won&#8217;t have later. <\/p>\n<p>Efficiency isn&#8217;t just a technical goal. It\u2019s a moral one. <\/p>\n<p>Stop over-complicating your scripts. Stop building &#8220;architectures&#8221; for things that are just tasks. Stop using Python like it\u2019s Java. <\/p>\n<p>Python was designed to be simple. It was designed to be readable. It was designed to get out of your way so you could solve problems. Somewhere along the way, we forgot that. We started building cathedrals when all we needed was a shed. <\/p>\n<p>I\u2019m going back outside. The rain has stopped, and I need to check the irrigation lines. The code is done. It\u2019s simple. It works. And most importantly, I can forget about it and do the real work.<\/p>\n<p>If you want to be a better developer, stop looking for the next framework. Pick up a shovel. Learn how the soil works. Then come back and look at your code. You\u2019ll see the rot. And you\u2019ll know exactly what to prune.<\/p>\n<hr \/>\n<p><strong>Final Pip Freeze (The &#8220;Clean&#8221; Version):<\/strong><\/p>\n<pre class=\"codehilite\"><code class=\"language-bash\">silas@thinkpad:~\/farm_ops$ pip freeze\nhttpx==0.27.0\nruff==0.3.0\n<\/code><\/pre>\n<p>No <code>pydantic<\/code>.
