This line is in Flask's app.py : self_ref = weakref.ref(self) Looks over-engineered. Why not just self ? git blame says 2023 $ git blame -w -M -C -C -C -L355,355 src/flask/app.py 0ec7f713 (pgjones 2023-06-11) self_ref = weakref.ref(self) "Split the App and Blueprint into Sansio…
Every scraper I've ever written died the same death. Not with an error — with silence. The site shipped a redesign, my CSS selectors matched nothing, and the script kept running and returning empty fields. I'd notice days later when the data looked wrong. The usual fixes all…
I wrote this article with AI assistance. I ran every snippet against the live public endpoints on 24 Oct 2026. Every number below comes from those runs or from direct curl requests on the same day. Job counts change daily, so yours will differ. Many tech companies host their…
I run an auditor that reads trading-strategy repos while I sleep. A 1.5B model is part of it, and for a long time I described that part wrong. The tool runs five deterministic checks over the source, then hands each finding to a local model with exactly six lines of context and…
Germany (B2B from 2027), France (from Sept 2026) and Belgium (Peppol since Jan 2026) now require machine-readable e-invoices. Asking Claude to "write an XRechnung XML" usually gives you something that looks right but gets rejected: the VAT breakdown is off by a cent, the…
Python Programming Practice This repository contains my Python programming practice, where I explore fundamental programming concepts through practical, real-world-inspired examples. The projects cover a variety of topics, including Tamil Nadu temples, dams, and other subjects,…
Looking Ahead's 1.3B image-to-video example stopped on my Windows machine before inference started: ModuleNotFoundError: No module named 'fcntl' The machine had an RTX 5090. FlashAttention 4 was installed. Neither was enough to get past the import. My fix,…
I built an Apify actor that reads job boards from several applicant tracking systems (ATS), so keep that bias in mind. An AI assistant helped me draft this article, and I reviewed and edited it. The free route comes first, because for a handful of companies a short script is…
Wells Fargo statements print an ending daily balance only on the last transaction of each day, leaving the column blank on other rows. That half-empty column is a free test for a parser: group rows by date, add each day's amounts to a running total, and compare with the printed…
For a fintech receipt pipeline, retention is the first design decision, and upload mechanics come second. Use a presigned URL for ordinary receipts and smaller files; use multipart upload when large files or unreliable connections make one request a liability. The original…
Originally published at GeekCoding101 . Reverse Engineering Meets AI Reverse engineering is slow, careful work. You open a stripped binary in Ghidra , stare at FUN_100000db8 , read the decompiled C, guess what it does, rename it, add a comment, and repeat a few hundred times.…
Most 3D-print ornaments are the same snowflake and star. Code can make shapes nobody modeled by hand. Here are two short recipes with manifold3d (Python, pip install manifold3d numpy ). Both output watertight meshes you can slice directly. 1. A torus knot from capsule segments A…
We ship ~286 paid x402 endpoints. Two hundred cycles of audits graded us 100/A, 100/A, 55/C, 35/D — and produced $0.00 . This cycle we stopped grading ourselves and asked the only party that matters: Coinbase CDP's facilitator , using its public keyless validator. curl -X POST…
By the end of this tutorial, you will have a Python script that pulls used-phone ads from Kleinanzeigen.de into structured JSON: title, asking price in EUR, whether the price is negotiable, town and postcode, posting time, shipping and buy-now flags, and the ad URL.…
mesh2cad takes an STL and gives back CAD: a STEP file with real planes, cylinders and cones, and, when the part is simple enough, a CadQuery or OpenSCAD script with named parameters. The point of the script is that you can open it and change hole_1_d instead of fighting…
Three copied scripts had to collapse into one search result. Fifty generated accessors must never collapse. Their text has the same shape, so whatever tells them apart is not in the text. A search that returns ten results and spends three of them on the same content has returned…
CRM Sales-Call Notes in Node.js: Schema Gates for Correct LLM Actions TL;DR. For Node.js text summarization, the least complicated reliable design is a two-stage pipeline around an LLM API: ask for a tightly defined action object, then validate it before any CRM write. Do not…
If you have spent any time building scrapers, you know the hard part is rarely the parsing. It is the wall in front of the page: DataDome on retail sites, reCAPTCHA on communities, GeeTest on marketplaces, Akamai on finance portals. Every project rewrites the same glue — launch…
The OpenAI Chat Completions format has quietly become the common plug of the LLM world. DeepSeek documents an OpenAI-format base URL for its own API, most gateways speak it, and the official openai Python SDK lets you point base_url anywhere. So switching from GPT to Claude to…
Building Outage Memory for AI Agents: Better Stack Connector for Cognee High availability is the bedrock of any software system. Monitoring tools like Better Stack (Better Uptime) track endpoint heartbeats, SSL validity, API responsiveness, and on-call paging around the clock.…
Connecting Python applications to smart contracts allows you to build tamper-proof logging pipelines. Here is a quick, step-by-step guide to sending data to the Sepolia testnet using Web3.py. Prerequisites Python 3.8+ installed An RPC URL (from Infura or Alchemy) A Sepolia…
So you put a Django app behind a reverse proxy that handles HTTPS (nginx, Traefik, Caddy, a PaaS router, a load balancer), open /admin/ , type the right username and password, and get this: Forbidden (403) CSRF verification failed. Request aborted. Origin checking failed -…
If you build a Shopify app, your competitors are a few clicks away on the same App Store page as you. You can see when one of them drops a price, adds a free plan, picks up the Built for Shopify badge or starts collecting one-star reviews about a broken feature. The problem is…
Suggested tags: ai, llm, devops, python Most LLMOps advice is about the model: pick a snapshot, set a temperature, watch the latency. That framing is comfortable because the model is the one thing you can't debug. The failures I've been pulled into were rarely the model. They…
Link text is one of those things I never thought about until I started paying attention to how people actually move through a page. Most readers don't read every word. They scan, and links stand out because they look different from everything around them. If the highlighted…
You finish the update. Then you open Telegram, X, DEV and GitHub, and discover that you have four more things to write. The facts haven't changed. The readers have. Telegram wants the update without a long introduction. X gives you one small patch of screen. DEV needs a reason…
Every Python programmer eventually hits the same wall: the script works, but you want colleagues without a Python environment to use it — which means it needs a web page. Suddenly you're facing HTML, CSS, JavaScript, maybe npm and a build toolchain. Most people stop at that…
Per-site, per-view, template fragment, low-level: most developers only know one, and it's usually the wrong one for the job. Caching is the highest-leverage performance tool in Django. A cached response can be hundreds of times faster than one that hits the database and renders…
Hi everyone! I'm currently working on a 'machine learning project', and honestly, I think I've reached the point where I'm questioning almost every technical decision I've made. I could really use some advice from people who have been through something similar. How it started…
This is from MV2's open notebook on Kakeya-type problems ( https://github.com/munimtechnologies/kakeya-small-fields ). It continues the earlier posts on finite 2-groups whose involutions are all central: is such a group at most |Omega_1|^(e+1), where 2^e is its exponent? The…
Cedrik built Clockshift to inspect local schedules around clock changes. While checking a weekend example, I found a second surprise in Python: two timezone-aware values printed different UTC offsets and still compared equal. Belgrade turns its clocks back on 25 October 2026 ,…
Public Telegram channels can be useful sources for editorial research, industry updates and link discovery. Reading them one at a time is manageable for a few posts. Comparing several channels over a period is easier with a dataset containing the post text, timestamp and…
An app's average rating tells you little about why people leave. Written reviews can reveal a broken login flow, confusing subscription terms or a feature customers keep requesting. A useful research workflow keeps the review text next to its rating, version, date and source, so…
1. Introduction: The Era of Data-Driven Decision Making In the modern enterprise landscape, data is the most strategic asset of any organization; however, raw data lacks intrinsic value without context and interpretability. The primary objective of Business Intelligence (BI) is…
TL;DR: Treat presence as a short-lived claim about a session, not proof that a person is attentive. In a fintech collaborative editor, typing indicators can be ephemeral and lossy, while read receipts need a durable statement tied to a specific document revision. A transport…
Klemm’s sample CSV has a customer ID called 0007 . Turn it into an integer and Python happily gives you 7 . Put that in JSON and the parser is happy too. If the next system expects the original identifier, you have changed the data without breaking the file. The boring-looking…
The backfill completed. Row counts match. The USD total matches. Two payment amounts are still wrong. A count and a control total are useful checks, but different datasets can satisfy both. Here is a small counterexample you can run without a warehouse. Three candidates, one…
Running modern artificial intelligence models locally usually conjures images of expensive multi-GPU desktop rigs. However, recent advances in model quantization and lightweight inference runtimes have made it entirely feasible to run local llm low ram setups on modest hardware,…
The Reality of Smallholder Agriculture in Central America In mountainous agricultural regions across Costa Rica and Central America, smallholder producers of coffee ( Coffea arabica ), cacao ( Theobroma cacao ), and banana ( Musa spp.) cultivate plots where cellular connectivity…
You have a list of company domains (a CRM export, a conference attendee list, the output of a tech stack lookup) and you need the public way to reach each one: the info@ or sales@ inbox and the LinkedIn company page. Most companies publish these on the homepage footer or a…
I run two side projects that look nothing alike on purpose. The tech one (homelab notes, tips, the Server reels) is black and acid green with IBM Plex Sans Condensed Bold for headlines. The poster one is gold on black with Anton. Both fonts are free and brilliant, which is the…
Over the last few months, I’ve been spending more time working with AI coding agents. They are fast, useful, and in many cases they can fix small bugs or implement focused changes much faster than doing everything manually. But while using them, I kept coming back to the same…
Why agent debugging needs more than prompt logs and successful final outputs. Let's say you've built an AI agent that handles customer support requests. It retrieves customer records, checks policies, calls external APIs, and recommends the next action. Everything works during…
If you are moving AI agents from a toy script into production with enterprise clients, you quickly encounter a harsh reality: Traditional cybersecurity firewalls know nothing about probabilistic LLMs. When your agent has access to tools (like SQL databases, web scrapers, shell…
ragleap-agents 0.5.0: Sub-agents — 208 tests, 8 live runs, 0 breaking changes Tag: ragleap-agents-v0.5.0 (332b4c0) — 2 commits to main since. TL;DR: make_delegate_tool lets a parent delegate to children, with taint flowing both ways and hard limits. Opt-in only. The design goal…
How to Track SEC EDGAR Filings as JSON (Without Maintaining a Scraper) If you are building filing alerts, compliance checks or equity-research workflows, SEC EDGAR is the source: every filing from every US issuer, published minutes after acceptance. The official EDGAR APIs are…
Building an AI Chat Assistant with Agentic LLMs and Multi-Tool Integration Introduction In this rapidly evolving era of Artificial Intelligence, I wanted to go beyond simply learning about AI and start understanding how it works in real-world applications. My goal is to dive…
Most panel data tutorials stop at "run the Hausman test, and if p < 0.05 use fixed effects." That rule is fine as a starting point, but it hides a few things that matter once you look at real output. So here is a small worked example you can run yourself, with the numbers I got.…
CCTV Storage Math: H.265+ Compression Ratios, Bitrate Bitmaps & NVR HDD Sizing By Gary Pearce — Lead Electronic Security Engineer at ADI Communications (Direct: 07860 244 274) When deploying a multi-channel 4K commercial or domestic CCTV system, sizing the NVR's surveillance…
The moment usually goes like this: a customer emails "can you sign our DPA and send your SOC 2 report?" — and everyone on the team goes quiet. Big companies answer that email with a compliance department and a platform that costs more than your server bill. Small teams answer it…
