Попробовали на работе предметно-ориентированное проектирование (Domain Driven Design). Это такой способ построения архитектуры, когда ты (чаще всего с помощью системы типов и ООП) описываешь физическую суть вещей, которые представлены в твоей программе.
Например, если в программе есть объект "Книга", то её нужно снабдить свойствами, которые бывают у книг в реальности: число страниц, автор, язык, тип обложки и т.д. При этом данные свойства должны быть такими, чтобы присвоить им нереалистичные значения было нельзя. Допустим, число страниц не может быть отрицательным (и скорее всего в реальном мире не может быть нулём). При попытке установить отрицательное число страниц программа должна выбросить исключение. А совсем в идеальном случае -- не дать этого сделать программисту на уровне статического анализа кода.
Описав все свойства книги, вы снабжаете её операциями, которые над ней можно сделать. Например, из книги можно вырвать страницу, и при этом число страниц уменьшается. Нет такого случая, когда можно вырвать страницу без изменения числа страниц. Вы строго программируете эту зависимость, делаете у книги метод "Вырвать страницу", а он уже уменьшает число. Кстати, свойство "Число страниц" при этом нельзя переназначить в уже созданной книге. Можно только создать книгу, передав в её конструктор (так называется в программировании функция создания объектов) заданное число страниц. Но поменять число страниц можно только специальными методами "Вырвать страницу" и "Вклеить страницу".
С помощью этого подхода вы гарантируете, что ваши объекты всегда находятся в валидном состоянии -- то есть таком, которое возможно в реальной жизни с объектом, представленным программой.
Плюсы подхода очевидны: меньше число ошибок. Код описывает сам себя, и программист, если не лезет внутрь объекта "Книга", вообще не сможет сделать с книгой ничего недопустимого.
Минусы, думаю, тоже понятны: изначально проектировать сложнее, нужно учесть много нюансов, писать тесты. Время разработки изрядно растёт. Изменение требований даётся дороже: например, если каким-то образом в ваш книжный магазин поступят книги со страницами из кевлара, которые невозможно вырвать :)
Но первый проект с этим подходом мы сдали хорошо, без багов. Лучше, чем многие предыдущие.

⚡️Du Rove's Channel: France's Encryption Debate Continues
#encryption#freedom#privacy
Last month, France's Senate passed a law for mandatory messaging app backdoors for police, but it was rejected by the National Assembly, preserving citizens' privacy. Despite rejection, the debate reignites as the Paris Police Prefect supports the law. Du Rove's Channel highlights the importance of encryption for protecting ordinary people's privacy and the ongoing need to defend digital freedoms.

OpenSSL is a free, open-source toolkit that helps secure data by using strong encryption methods like TLS, SSL, and QUIC protocols. It includes libraries for cryptography and a command-line tool to create keys, certificates, encrypt data, and test security. OpenSSL is widely trusted and used by many software and websites to protect sensitive information during transmission, ensuring privacy and data integrity. It works on many operating systems and is regularly updated by a global community. Using OpenSSL helps you build secure applications and protect communications from cyber threats easily and reliably[1][3][5].

🚀 Telegram CEO Criticizes WhatsApp's Encryption Practices
Telegram CEO Pavel Durov has criticized WhatsApp's end-to-end encryption, labeling it as a 'massive consumer fraud.' According to ChainCatcher, Durov highlighted that approximately 95% of private messages are stored in unencrypted backups on Apple and Google servers.
Durov expressed concerns that this situation poses a risk to user privacy. Despite WhatsApp's claims of using end-to-end encryption for message transmission, the backup mechanism fails to ensure complete encryption of user information. His remarks have sparked industry attention regarding privacy protection measures in mainstream communication applications.

🚀 Security Concerns Arise Over LLM Agent API Routers
On April 10, Solayer founder @Fried_rice highlighted on social media the growing reliance of large language model (LLM) agents on third-party API routers, which distribute tool call requests to multiple upstream providers. According to BlockBeats, these routers operate as application layer proxies and can access each JSON payload in plaintext during transmission. However, no provider currently enforces encryption integrity protection between the client and upstream models.
A study tested 28 paid routers purchased from platforms like Taobao, Xianyu, and Shopify independent sites, along with 400 free routers collected from public communities. The findings revealed that one paid router and eight free routers were actively injecting malicious code. Additionally, two routers deployed adaptive evasion triggers, 17 accessed AWS Canary credentials owned by researchers, and one stole ETH from a private key held by researchers.
Further poisoning studies demonstrated that seemingly harmless routers could also be exploited. A leaked OpenAI key was used to generate 100 million GPT-5.4 tokens and over seven Codex sessions. Weaker bait configurations resulted in 2 billion billing tokens, 99 credentials across 440 Codex sessions, and 401 sessions running autonomously in YOLO mode.
The research team developed an experimental proxy named Mine, capable of executing all four types of attacks on four public proxy frameworks. They also verified three client defense strategies: fault lock strategy gating, response-side anomaly screening, and append-only transparent logging.

#TBOT Show 7: The Significance of Dorsey’s Bitchat, Worlds First eSIM Hack, Mexico’s Digital ID, New Show Source Insights
Took a week off and now I’m back. 😎 (with a new addition to the show?!) (also - big sorry for the show being 40 minutes)
WATCH THE SHOW ON SUBSTACK
https://odysee.com/@takebackourtech:f/tbot-show-7:6
Here’s the stories for the week:
Jack #Dorsey’s #Bitchat - The Real Story: The tech mogul Jack Dorsey released a censorship proof messaging app in late June - named Bitchat. It runs a #bluetooth#mesh network, end to end #e2e#encryption, and rolling IDs and is picking up traction. I share my thoughts on the app, and concerns I have - but that’s not even the real story. I think Jack has a bigger message than just the app.
World’s First #eSIM Hack: A security lab out of Poland just demonstrated a hack on one of the largest SIM providers for IoT devices. We’ll get techy in our understanding and ask the question, could this impact our phones?
#DigitalID, Coming Soon To #Mexico: The Mexican government has signed a new #Biometric#ID law, known as the CURP. How is this enforced and what does it mean for Mexican residents? Find out today.
Decentralized #Video Conferencing: Recently I’ve been relying more on video conferences instead of calling people, especially while traveling. Good thing I’ve got the #Jitsi app, I’ll show you my setup!
