One thing I’ve learned in my first 10 months at Meta… Don’t ask a senior eng what to do or how to do something. Instead, explore different approaches and ask the senior eng which they would recommend. For example, when devising the tech plan for a new feature that requires storing and retrieving new data, don’t simply ask what data solution you should use. Instead, scour internal wikis, existing code patterns, etc, to learn about the data storage solutions available. Then list out the pros and cons specific to your use case in terms of latency cost, capacity usage, reliability, implementation complexity, etc. Sending that breakdown to the senior eng (along with your own proposal for what you think the best choice is) will not only make their lives easier, but prove to them that you’re capable of working at the next level. Of course, there are exceptions. For example, if there’s a quick question that a senior engineer could answer in 30 seconds, but would take you 2 hours to figure out on your own, it makes sense to ask. What do others think? What types of questions should you ask senior eng and how should you decide whether to ask a question or figure it out on your own? #softwareengineer

🚀 How to Approach a System Design Interview: Amazon Prime Video Example When tackling a system design problem, especially for a complex platform like Amazon Prime Video, it's crucial to approach it strategically. Here's how I break it down: Get clarity on the requirements, both functional and non-functional. Focus on the user flows, define the scale, detail out the components, improve scalability, and wrap up confidently. Pro Tip for Interviews: Don’t rush into drawing diagrams! Ask clarifying questions, understand the problem fully, and then build the system piece by piece. Communicate your thought process clearly, and focus on scalability, reliability, and cost-efficiency. Remember, the trick is to think aloud—explain why you're making certain decisions. The interviewer wants to understand your reasoning as much as the final solution! Good luck to all those preparing for system design interviews! You've got this!💪 Want to master system design interviews and land those $500k+ TPM roles? Make sure you're fully prepared with the Kracd.com interview prep course.

I'm interested to know what most people might think of this? ❔ So I just read from a post by Al Jazeera Media Network on Instagram that said "Gen-Z and Millennials are shifting towards old-school phones", primarily because of how addictive social apps are these days and how they spent most of their time viewing screens. It also explained how, as a result of this, companies are emerging that are solely focused on developing these "old-school" phones to cater this and I think they actually might capture some traction. But what if they don't need to be old-school? What if we've had these AI-Powered Mini-phones, that rely on voice commands and advanced scheduling and automation features which would enable all the "productive tasks" and yet keep all the dirt away? Let me know what you think of this concept? An AI-Generated concept is attached as well. #research #ai #smartphones #futureoftechnology

Last week, I spoke with three different Turkish devs who just landed dream roles at UK tech firms. Amazing salaries, great opportunities... but by day 3, all three were secretly terrified. Why? The reality of that first week hits DIFFERENT. One senior dev put it perfectly: "In the interview, I felt like a tech genius. Now I feel like a junior who can't even explain what I did yesterday." After teaching English to 1000+ Turkish professionals, I know it's a pattern. That first week in an international company brings challenges nobody prepares you for. Here's what REALLY happens in your first week: Day 1: Everyone's speaking lightning-fast - not that slow, clear "interview English" you prepared for. Day 2: Random Slack messages pop up. Should you reply formally? Use emojis? You freeze at every notification. Day 3: First standup. You practiced for hours, but someone asks "any blockers?" and your mind goes blank. The raw truth from my experience: 90% of Turkish devs consider quitting in week one Everyone thinks they're the only one struggling. By week 4, most are thriving. If they make it that far. Here are 3 survival strategies that have helped my students crush that first week: 1. The "Shadow Method": Record meetings (with permission) Replay them after hours Learn the team's communication patterns Why it works: You'll start recognizing recurring phrases and meeting flows 2. The "Slack First" Approach: Master written communication before verbal Yes, those emojis are professional 😊 Build confidence in chat before diving into calls Why it works: Written responses give you time to think and build confidence 2. The "Transparent Dev" Technique: Tell your team it's your first international role Be upfront about communication challenges Watch how supportive most teams become Why it works: Teams adjust their communication when they understand your situation A secret most Turkish devs discover too late: International teams care more about clear communication than perfect English. They'd rather hear your ideas in simple words than miss out on your expertise. Your first week will feel like jumping into cold water. But here's what no one tells you: By week 4, you'll be swimming. Want more specific strategies for crushing your first month in an international team? Drop a "first week survival" comment below. If enough people need this, I'll share the exact playbook that's helped dozens of #Turkish devs thrive in global companies. #remotework #techcareers #engineering #engineeringjobs #language

January 2008 - California, United States. Jan Koum, an engineer at Yahoo, applies for work at Facebook - rejected. It was not the end - he moved on with his life. He buys an iPhone next year and immediately recognizes the huge potential of the new App Store. So he decided to build an instant messenger with some of his former coworkers from Yahoo. And named it WhatsApp. The vision behind WhatsApp was to replace the expensive SMS. With 1 million people signing up each day, the growth rate of WhatsApp was mind-boggling. WhatsApp was able to support 50 billion messages a day from 450 million daily active users. And they did it with only 32 engineers. WhatsApp is one of the most successful instant messengers in the market. In 2014, the same Facebook that rejected Jan Koum acquired WhatsApp for a whopping 19 billion USD. According to Forbes, Jan Koum has a net worth of 14 billion USD in 2023. Rejection can be redirection. Jan Koum's journey from rejection to revolutionizing communication with WhatsApp teaches us that setbacks are often stepping stones to success. Keep moving forward, for opportunities await those who persevere.

Being an #engineering #team #lead is a challenging and exciting, yet sometimes lonely role. What could be better than having a community of TLs to help & support each other, learn, and grow together 🤟 ? This is why we established the Wix Server TL Forum. The Wix IL Server TL community has existed for over a decade (Yes! a decade!), but in the last 6 months, we've completely transformed it: We meet biweekly, with each meetup focused on a preselected topic. A sub-team of TLs creates and drives the sessions and discussion groups, allowing the entire forum to share experiences, best practices, and improve together. In the last 6 months, we've covered many hot topics: 🔥 TL role expectations 🔥 Quality! (including reliability, bugs & performance) - how to measure, achieve, and balance with progression 🔥 Effective Code Reviews 🔥 Effective On-Call Practices 🔥 Milestone Planning and Executions 🔥 Mapping & Overcoming Velocity Killers 🔥 Effective Knowledge Sharing Coming soon: 🔥 Product <-> Dev Collaboration 🔥 TL <-> HR Collaboration Looking forward to more leadership learning and fun! 🤩 We’re always on the lookout for talented TLs, so check out our open TL and non-TL positions: https://lnkd.in/duFHZBKU #Leadership #Engineering #TeamLead #Wix #KnowledgeSharing #CareerOpportunities

"Blazing Fast: Uber Serves 40 Million Requests per Second, Slashing CPU Cores by 95% from 60K to Just 3K, with Integrated Cache" 🚀 Don't Just Band-Aid Your Performance: Cache Like a Pro 🛠️ Cache is every developer's first line of defense against sluggish apps. But simply throwing a cache at a problem is like slapping a bandage on a gushing wound. It might offer temporary relief, but it won't fix the underlying issue. Uber’s epic struggle: While trying to make their apps faster and able to handle more users while stuck with old-fashioned storage. When there's suddenly a massive increase in people wanting to read data, it pushes them right to the edge of disaster. ❌❌ A BIG TECH HURDLE❌❌ Solution: Docstore comes to the rescue. Beyond the Quick Fix: 1.DocStore Query patterns - It turned out that more than 50% of the queries coming to Docstore are ReadRows requests. Build what’s required and what makes sense. 2.Bypassing Cache - Bypassing the cache in Uber's microservices ensures strong consistency for critical flows like retrieving items in an eater's cart, while leveraging cache for less critical tasks such as fetching a restaurant's menu. 3.Brilliant Cache Invalidation Strategy using CDC and Flux - Cache Invalidation is one of the critical problems in Software Development. This strategy ensures cache consistency within seconds, preventing the risk of uncommitted transactions affecting cache integrity. 4. Special Redis Codec for Row Reads: Unique row values in MySQL are cached in Redis using a special codec to ensure compatibility. This facilitates sharing cache resources across databases while maintaining data isolation. 5. Cache Warming and Cross-Region Replication: Instead of using inbuilt Redis replication, Leveraging the Query Engine for Cross-Region Replication ensures consistency. 6. Sharding Differently: Sharding Redis clusters differently from the database scheme optimizes caching for diverse data access patterns, enhancing overall system performance and scalability while resolving potential inefficiencies in cache management and data retrieval. 7. Adaptive Timeouts: Optimizing Redis Performance with Dynamic Timeouts. This prevents issues like premature failures or excessive latencies. Percentile latency ranges: P75 latency decreases by 75%, and P99.9 latency drops by over 67%, all while curbing latency spikes. ⏱️ As of the current date, CacheFront supports over 40M requests per second across all production Docstore instances, with continuous expansion. 📈 Blog Link : https://lnkd.in/ghvAY3_Z This is undoubtedly one of the finest reads I've encountered on distributed cache systems. I highly recommend giving it a read. 📚 Big Thanks to Preetham Reddy Narayanareddy Afshin Salek Piyush Patel Zurab Kutsia Eli (Oleg) Pozniansky #Systemdesign #distributedcache #cache #p99latency #systemdesign #design

💸 Amazon Fails to Stand Behind Quality Assurance - Defective Sony WH-CH720N Headphones 💸 I recently purchased Sony’s WH-CH720N headphones on Amazon, investing ₹8000 of my savings. Unfortunately, the product arrived with severe issues: loud internal noise when touched and disappointing sound quality, not even comparable to ₹2000 earphones. Here’s where the real frustration begins: Instead of standing behind the quality of the products they sell, Amazon flatly refused a return or replacement, pushing me to travel 200 km to a Sony service center — one that’s inconveniently closed on weekends, making this even more impossible for working individuals like me. After years of loyalty, it’s disheartening to see Amazon sidestepping responsibility for a defective product that costs a significant amount. As customers, we deserve better: - Amazon should reassess its policies on defective items, especially for high-value purchases. - Accountability and consumer support must come first, especially when e-commerce platforms are supposed to simplify life, not create unnecessary stress. Has anyone else faced a similar issue with Amazon’s return policies? Any advice on getting this resolved? This experience has shaken my trust in Amazon. #Amazon #CustomerSupportFail #ConsumerRights #Frustration #Ecommerce

Hey everyone, Have you been fascinated by the future of artificial intelligence? Mustafa Suleyman's recent TED talk really impressed me! He offered a thought-provoking perspective on what AI really is. I find his idea of seeing AI as a digital species very compelling. Based on my experience in the IT industry, I can't disagree with Suleyman's emphasis on the potential trend in advancing conversational interfaces. He forecasted that eventually, every digital interface will integrate this functionality. While I agree with Suleyman's perspective that our future will be greatly influenced by technology, I believe it's crucial that we approach this transformation thoughtfully. If you haven't watched the video, I strongly recommend checking it out for some fresh insights into this subject. https://lnkd.in/gwYWCb7f
