Website Description
Jacob Baytelman: Personal blog of a developer with many years of experience
Btlr website. com is the personal platform of Yakov Beitelman, who positions himself as CTO, founder and full stack developer. Starting his journey in the software industry back in 1998, he shares his experience in creating, testing and launching solutions. This is not just a corporate site, but rather a collection of thoughts, articles and recommendations from a practicing engineer. The main topics of the resource cover a wide range of issues in the IT industry. Here you can find deep thoughts on security, UXUI design and managing remote teams. Yakov writes extensively in Russian and Ukrainian, touching on topics such as the future of innovation, the impact of social networks on business, and even the philosophical aspects of programming. For example, he argues that good programmers rarely create startups because they tend to overestimate the complexity of problems. Particular attention is paid to cybersecurity issues. The author reminds that security headers are instructions that are often ignored, even though they are critical to protecting against XSS and other attacks. He also shares his personal experience with email as a key productivity tool, arguing that mail has remained the main communication channel for decades. The site's blogs also raise social issues. There are articles about how Facebook advertising can kill a business due to intrusive targeting and why garage startups are no longer relevant. Yakov also writes about educational issues, criticizing school computer science programs for becoming obsolete. He believes that teaching basic languages like Pascal or Basic in schools is pointless, since this knowledge quickly loses value. In addition, the site contains materials about cryptocurrencies, cloud technologies and ethical aspects of storing user data. Beitelman insists that users' data belongs to them, not the platform, and the right to complete removal of information should be absolute. This is a site for those who are interested not only in code, but also in the context in which that code is created and used.Key blog topics
- Development and architecture:Tips on creating APIs, working with frameworks and choosing technologies.
- Security:Discussion of security headers, tamper protection, and data management.
- Startups and business:Analysis of the investment market, the impact of social networks on marketing and the realities of remote work.
- Education and career:Criticism of the modern IT education system and advice on skill development.
