Designing a Concurrent Donation Ledger With FastAPI and PostgreSQL

Every year, billions of dollars flow through online crowdfunding platforms, leading to donor concerns about the allocation of funds. Traditional crowdfunding applications lack transparency, often leaving funds in unverified balances without real-time auditability or guarantees against double-allocations. GoodCause, a social impact platform, aims to address this issue by creating a system that ensures financial integrity and atomic fund distribution. Its architecture is based on mobile-first delivery, atomic auditability, and strict data isolation, utilizing technologies such as React Native, FastAPI, and PostgreSQL. The platform incorporates a mobile client for cross-platform navigation, a backend API for domain-driven routing, a database with Row-Level Security, and a payment gateway for secure transactions. A significant engineering challenge is preventing race conditions and double-spending in concurrent donation scenarios.

We Got a $240,000 Estimate for Agent API Access. Our Agent Suggested a $5 Postgres Instance.

The operational landscape at SaaStr has changed significantly with the integration of AI, particularly with the AI VP of Revenue, 10K, which manages most outbound, inbound, and revenue operations and executes 35,000 to 40,000 API calls daily. Salesforce, Atlassian, and HubSpot are now charging for agent access, with estimates suggesting that maintaining 10K could cost around 0,000 annually. 10K has proposed mirroring the system of record into a Postgres database to reduce API call costs. Previous limitations with Marketo restricted API access to 10 or 20 minutes daily, prompting a migration away from it. The cloud index has risen by 18%, while vendors relying solely on per-seat sales are struggling. Data shows that 49.7% of executives changed jobs in the last 16 months, with 63% of CMOs doing the same. Additionally, more than 75% of AI-native attendees at SaaStr events had never attended before. 10K is now tracking its own API calls and reducing unnecessary ones, while a Postgres mirror is being considered for vendors with high agent pricing. Muse is being tested for ad capabilities against Claude and Replit.

Antivirus: Do you still need it?

Purchasing antivirus software is often seen as necessary but can be frustrating, especially with built-in security features available on most computers. Windows includes Microsoft Defender Antivirus, which has been independently tested and scored well for protection, performance, and usability. Mac users have XProtect for malware detection. Users should verify that their existing protection is enabled and up-to-date before considering a subscription. Antivirus programs combat various types of malware, using methods like signature scanning and heuristic analysis, but they are not infallible. Research on antivirus effectiveness varies, with scores reflecting different criteria and not universally applicable detection rates. Subscriptions may be worthwhile if they offer specific features, but users should be cautious about renewal prices and unnecessary multiple installations. Maintaining updated software and practicing good security habits are essential for protection. For everyday use, built-in protection is often sufficient unless additional benefits justify the cost of extra software.

What Is APK and What to Check Before You Download Game Online

- An APK is the file format Android uses to distribute and install apps. - Real-money gambling apps like Mega888 are often distributed as direct APK downloads from their own sites or through agents. - Mega888 is designed to run as an installed application rather than a website. - Players usually get their login details and credits through an agent or platform representative. - Online gambling regulations differ from country to country, affecting the availability of platforms like Mega888. - Before downloading any casino APK, it is important to check the source reputation, permissions, run an antivirus scan, be cautious with payments, use separate credentials, and keep the phone updated. - The legality of Mega888 depends on the country you live in, as online gambling is regulated or banned in many places. - Common problems with installing Mega888 APK include "App not installed" error, "Blocked by Play Protect" warning, app crashes on launch, and login issues.

Challengers Approach: Third Party App Stores Arrive to Google Play

Google has begun allowing rival, third-party app stores to be included within the Google Play Store, providing developers with more options for billing and app distribution. This change follows a court order resulting from Epic Games' antitrust lawsuit against Google, which challenged the company's restrictions on alternative app stores and in-app payment rules. The inclusion of these third-party stores enhances competition within the Android ecosystem, reducing Google's dominance and empowering users and developers with more choices. Users can now opt for alternative app stores if they are dissatisfied with Google's services, improving opportunities for privacy and security.

Kaspersky: 5 Security Essentials Beyond Built-In Antivirus

India's internet usage has rapidly evolved, with the Unified Payments Interface (UPI) transforming smartphones into banking hubs and daily tasks being conducted online.
