The recent CrowdStrike update causing widespread outages is deeply troubling. With over 25 years of experience leading critical systems releases, I understand the challenges, but outages of this magnitude demand answers. Even the most talented programmers encounter defects, some frustratingly elusive. This is why robust quality assurance (QA) processes are an absolute necessity, especially for software entrusted with safeguarding our systems. Throughout my career, I've championed a multi-layered QA approach that acts as a safety net, scrutinizing software from every angle. This includes: ➡️ Code Reviews: Regular peer reviews by fellow developers identify potential issues early. ➡️ Testing Pyramid: A range of tests, from focused unit tests to comprehensive system and integration tests mimicking real-world use, are employed. ➡️ Stress and Capacity Testing: Pushing software beyond its normal limits helps expose vulnerabilities that might otherwise remain hidden. ➡️ Soak Testing: Simulating extended periods of real-world use uncovers bugs that only manifest under prolonged load. By implementing these techniques, QA teams significantly increase the likelihood of catching critical defects before they impact users. CrowdStrike owes its customers transparency. A thorough investigation and a clear explanation of how such a disruptive bug bypassed safeguards are crucial. Understanding this will help prevent similar incidents in the future. This outage serves as a stark reminder for both software providers and buyers. Providers must prioritize rigorous QA processes. But buyers also have a role to play. I urge all software buyers to carefully audit their vendors' QA practices. Don't settle for anything less than a robust and multi-layered approach. Our security depends on it. Our economy and indeed our life today, depends on software. We cannot allow this type of outage to disrupt us in the future! By prioritizing rigorous testing and demanding transparency, we can work together to ensure the software we rely on remains a source of security, not disruption. _______________ ➡️ About Me: I'm Talila Millman a fractional CTO and a management advisor, keynote speaker, and executive coach.

The Promotion Secret Most Professionals Discover Too Late   In over two decades of executive recruitment, I've observed a pattern among professionals who consistently advance in their careers versus those who stagnate despite equal talent and effort.   The difference? Strategic documentation of achievements, what I call a professional "brag book."   This isn't about boasting. It's about recognizing the reality of corporate decision-making: in quarterly review cycles and fast-paced environments, even exceptional work becomes invisible without proper documentation.   Your comprehensive brag book should include:   1️⃣ Achievement Portfolio: Concrete evidence of promotions, awards, successful projects, and initiatives that demonstrate your ability to deliver results   2️⃣ Quantifiable Impact: Specific metrics that translate your efforts into business value; revenue generated, costs reduced, efficiency improved, or risks mitigated   3️⃣ External Validation: Preserved testimonials from clients, acknowledgments from leadership, and formal recognition that provides third-party credibility   4️⃣ Leadership Moments: Documented instances where you identified problems independently and implemented solutions beyond your job description   The professionals I place in competitive positions understand a fundamental truth about organizational dynamics: visibility strategically created through documented evidence consistently outweighs undocumented effort, regardless of quality.   Update your brag book quarterly and bring it with you to performance discussions. Make it impossible for decision-makers to overlook your value when advancement opportunities arise.   Sign up to my newsletter for more corporate insights and truths here: https://lnkd.in/ei_uQjju   #deepalivyas #eliterecruiter #recruiter #recruitment #jobsearch #corporate #careeradvancement #workplacesurvival #selfadvocacy #careerstrategist

5 Best Practices for Technical Writing: But, let's first discuss Why Developers Need to Write Online: - As developers, we rely heavily on technical documentation and articles to deepen our understanding and troubleshoot problems. The ability to communicate technical topics effectively is a must-have skill. Yet many developers avoid writing for fear of not being "expert" enough. I'm here to tell you that you don't need to be an expert to start sharing your knowledge. In fact, writing about what you're learning is one of the best ways to solidify concepts. - The key is to be brief, avoid fluff, and structure content logically. Follow these best practices to level up your technical writing skills: 1. Organize content logically and remove fluff 2. Break complex topics into simple, step-by-step explanations 3. Use headings, bullet points, code-blocks, relevant images and white space for easy scanning 4. Use examples and analogies to illustrate concepts 5. Offer multiple learning pathways with cross-references Start small by documenting solutions to problems you've solved. Publish your writing online to help fellow developers and demonstrate your skills. Be respectful of your readers’ time; they’ll love you for it. #technicalwriting #developercommunity #proofofwork #documentation

🚫 Debunking Common Career Advancement Myths 🚫 "Hard work alone will earn you that promotion." Simply putting in the hours isn't always enough. Visibility and strategic efforts are key. "Staying silent and working diligently will get you ahead." Being reserved about your achievements can actually hold you back. Speak up about your goals. "Being busy means you're making progress." Activity doesn’t always equal advancement. Focus on work that aligns with the company's objectives and drives meaningful results. ✨ A Smarter Approach: 🔹 Build Self-Confidence: Recognize and demonstrate your value in all professional interactions. 🔹 Be Proactive: Communicate your career goals clearly to your leaders and seek opportunities to showcase your aspirations. 🔹 Work Strategically: Prioritize tasks that contribute significantly to organizational goals, rather than just being busy. Elevate your career by challenging these myths and adopting a more effective strategy. 🚀 #CareerGrowth #ProfessionalDevelopment #Leadership #WorkSmart #CareerAdvancement

Old career advancement: - Keep your head down and focus only on tasks - Assume your boss remembers your goals - Wait for annual reviews to discuss growth - Work hard and hope someone notices New career advancement: - Keep multiple career options open - Share valuable content with your network - Reach out to peers from different companies - Build networks beyond your immediate team - Add value through thoughtful LinkedIn comments - Connect with senior leaders from other departments - Repeat your promotion goals and trajectory regularly - Keep detailed records of project approvals and praise - Schedule monthly career conversations with your boss - Ask colleagues to send congratulatory emails about your work - Record testimonials from leadership and cross-functional teams I learned this after watching talented people get overlooked while others advanced quickly. The difference wasn't talent or hard work. Just strategic career management. Your boss has 20 other priorities. Your colleagues will look out only for themselves. You have to focus on your career selfishly, or no one else will do it for you. So document your wins, communicate your goals, and expand your circle. Because career growth doesn't happen by accident - it happens by design. #career #AI #job #work
