UI Bakery vs. Retool: A Comprehensive Comparison

When comparing UI Bakery and Retool for operating in-house data and creating dashboards with charts, both platforms offer strong capabilities but have some key differences. Letโ€™s examine how they compare in these specific areas: Data Handling and Integration Retool Retool excels in data handling and integration, making it a strong choice for operating in-house data[1][4]. It offers: Powerful integration with external data sources, including APIs, databases, and cloud services Support for SQL/NoSQL databases and services like Firebase, MongoDB, and PostgreSQL Real-time data syncing between the UI and data sources UI Bakery ...

AppWrite vs. Supabase: A Comprehensive Comparison

Itโ€™s difficult to definitively say one is โ€œbetterโ€ than the other, as each has its strengths and is suited for different use cases. However, I can provide a comparison of their key features and performance to help you make an informed decision: Performance and Scalability Appwrite consistently outperformed Supabase in stress tests, especially when scaling up to handle more users[1][4]. For example: On a โ‚ฌ5/month self-hosted server, Appwrite handled up to 2,000 users per day comfortably, while Supabase struggled with larger loads[1]. On a more powerful โ‚ฌ30/month server, Appwrite managed up to 250 simultaneous users, while Supabase hit its limit at only 45 users[1]. In breakpoint tests, Appwrite reached 6,800 virtual users, processing 100,000 requests with an average 3-second response time. Supabase reached its breakpoint at 3,000 virtual users, with 59,000 requests and a 6-second average response time[4]. Ease of Use Appwrite offers a smoother self-hosting experience with fewer restrictions and less setup complexity[1][3]. Supabase can be more challenging to configure in a self-hosted environment and has some features restricted or limited when self-hosted[1][3]. Features Both platforms offer similar core features, including authentication, databases, storage, and serverless functions. However, there are some differences: ...

PostgreSQL Connection Modes(Session Mode vs. Transaction Mode)

Connection Mode (Session Mode) Each client maintains a dedicated connection to the database for the entire session duration[2]. The connection is only released back to the pool when the client disconnects from the database[2]. This mode replicates a direct connection to PostgreSQL and supports all PostgreSQL features and mechanisms[2]. Itโ€™s safer and more compatible with all PostgreSQL clients[2]. Does not significantly reduce the load on database resources[2]. Transaction Mode The connection to PostgreSQL is maintained only for the duration of a transaction[2]. When the transaction completes, the connection is returned to the pool and can be reused by other clients[2]. Allows for a higher number of client connections (up to 10,000) with a smaller pool size[2]. Reduces the load on DBMS resources, especially beneficial for a large number of low-load client connections[2]. More efficient in terms of resource utilization, as idle connections are released back to the pool[3]. Key Differences Connection Duration: ...

Managing and Overcoming Burnout (feat. Mannerism, Slump)

The word โ€œburnoutโ€ is being heard from all directions. It is being expressed as a reason for quitting, changing jobs, taking vacations, and as a way to express difficulties in life. I think everyone has heard it at least once, and I believe there have been times when youโ€™ve wondered if you are experiencing burnout. When I hear people talking about burnout, I often feel a deep sense of sympathy, but I also feel that there is little I can do to help. I can suggest various things to try, but those who are experiencing burnout often donโ€™t seem to hear those suggestions. So, while contemplating what to do, I decided to write this. ...
