?? ???????????????????????? ???????? ???????????????????? ???? Bluetick Consultants Inc.. Being a developer isn’t just about writing code—it’s about solving real-world problems, managing expectations, and constantly learning from every challenge we encounter. At Bluetick, I primarily focus on backend development, but as we all know, challenges don’t come neatly categorized. One such challenge I faced recently was email delays due to large attachments. ?????? ??????????????: Users were experiencing painfully long load times when sending emails with large attachments. Why? Because the entire email-sending process—attachment handling, email composition, and sending—was happening synchronously in the main request thread. ????????????? ?? Users had to wait until the email was completely sent before getting a response. ? This made the app feel slow and unresponsive. ?? ?????? ????????????????: Instead of blocking the main request cycle, I leveraged threading + asyncio to offload the heavy lifting to a separate thread. ??? ???? ?????????? ?????????????????? + ??????????????: ? The email-sending process now runs asynchronously in the background. ? The user gets an instant response instead of waiting. ? Impact: Response time dropped from 46.67 seconds to just 31 milliseconds! ?????? ???????? ??????????????: If you’re working on a backend-heavy application, you’ve likely faced similar bottlenecks. By carefully choosing asynchronous processing, you can drastically improve user experience without compromising functionality. At Bluetick Consultants Inc., we've helped our clients build high-performance, scalable applications with optimized backend architectures that solve real-world challenges.

?? ???????????? ???????????????? ???????????????? ?????????? ???????????????????? ???????? (?????? ?????? ???? ?????????? ????????) Let's be honest—security is often the last thing we think about when writing code. We prioritize features, deadlines, and performance, but security? That’s usually an afterthought. If you're a Rails developer (or managing a team that uses Rails), here are some real-world security pitfalls you need to be aware of—and how to fix them. ??. ???????? ???????????????????? ?????????????????????????????? – ?????? ???????????? ???????????? The Mistake: Using update(params[:user]) or User.new(params[:user])? Without whitelisting, attackers can overwrite critical fields like admin: true or balance: 1_000_000. The Fix: Use Strong Parameters in controllers: ???< params.require(:user).permit(:name, :email, :age) > ??. ?????? ?????????????????? – ?????????????? ???????? ???????????????? ???????? ???? ???????? ???????????????????? The Mistake: Using string interpolation inside queries: ???< User.where("email = '#{params[:email]}'") > This allows attackers to inject SQL, like ' OR 1=1 --, which grants them access to everything. The Fix: Always use parameterized queries: ???< User.where(email: params[:email]) > ??. ??????????-???????? ?????????????????? (??????) – ???????????????? ???????? ???????????????? & ???????? The Mistake: Displaying user input without escaping it in views: ???< %= @comment.content % > If an attacker injects <script>alert('Hacked!')</script>, the browser executes it, compromising user accounts. The Fix: Use h() or <%= %> (ERB’s default behavior) to escape untrusted input: ???<%= h(@comment.content) %> For advanced cases requiring some HTML, use Rails' sanitization helpers: ???<%= sanitize(@comment.content, tags: %w(p strong em)) %> ??. ???????????????? ???????? ?????????????? – ???????? ?????????????? ?????????? ?????????????? ???????? ???????? ?????? The Mistake: Allowing unrestricted file uploads means someone could upload a .exe, .php, or .js file and execute arbitrary code on your server. The Fix: ? Restrict file types with Active Storage or CarrierWave. ? Store uploads outside the app directory (e.g., AWS S3, not /public/uploads). ? Use a CDN/domain to serve files and prevent XSS. ??. ?????????????????? ?????????????? ???? ???????? – ?? ???????????????? ?????????????? ???? ???????????? The Mistake: Storing secrets directly in the repository: API_KEY = "my-super-secret-key" If this key leaks (which happens a lot in public repos), your API is compromised. The Fix: Use Rails credentials (config/credentials.yml.enc): ???< EDITOR="nano" rails credentials:edit > At Bluetick Consultants Inc., we build secure, scalable, and high-performance Ruby on Rails applications.

Ever feel like your app is stuck in a traffic jam???? ?? Here’s the thing: traditional threads are like adding more lanes—it helps, but not enough. Elixir Process takes a different approach. They’re lightweight (think millions of them chatting at once), don’t block each other, and run in parallel without breaking a sweat. No shared memory means no conflicts, and OTP’s supervision trees ensure fault tolerance by automatically restarting failed processes. At Bluetick Consultants Inc., we are building systems that handle 10M+ tasks simultaneously, powering high-performance, resilient applications. Because in today’s world, slow code isn’t just frustrating—it’s costly. Curious how this could transform your system? Let’s discuss! #Elixir #Concurrency #ScalableSystems #TechInsights #Linkedinvideos
