We are thrilled to announce the general availability of Red Hat OpenShift Service Mesh 3.2. This release includes the general availability of Istio’s ambient mode—a new way of deploying service mesh without sidecars that significantly lowers the resource costs of using service mesh. This provides a low overhead solution for zero trust networking with lightweight pod-to-pod mTLS encryption and authorization policies based on workload identities, with the ability to add more advanced features as required.Based on the Istio, Envoy, and Kiali projects, this release updates the version of Istio

In a modern cluster, the hardest problem isn’t running workloads—it's sharing resources fairly. Red Hat OpenShift clusters are seeing a surge of AI-accelerated workloads, from GPU-intensive training jobs to large batches of inference requests. At the same time, other tenants still need consistent throughput for their everyday CI/CD pipelines and data processing tasks. The result is a constant battle for resources, where some jobs wait too long, others consume more than their fair share, and administrators are left fighting bottlenecks.This is exactly the challenge that Kueue, a Kubernetes-

چرا لینوکس و چرا در دواپس مهم هست .

تسلط عمیق به لینوکس باعث می‌شود مکانیسم‌های بنیادین سیستم مثل Memory Management، I/O، Networking، Process Lifecycle، Filesystem و Kernel Behavior را بفهمی.

همین مفاهیم پایه هستند که تفکر زیرساختی (Infrastructure Thinking) را می‌سازند.

وقتی این تفکر را داری، در DevOps، Security، Cloud، Storage و Database:

بهتر Performance Tuning انجام می‌دهی،

Root Cause Analysis را سریع‌تر پیدا می‌کنی،

راهکارهای متفاوت می‌بینی چون ساختار را از ریشه می‌فهمی نه از سطح،

و وابسته به ابزار نمی‌شوی.

«کسی که cgroups، namespaces و scheduling را بفهمد، Docker را بهتر از کسی که فقط دوره دیده می‌فهمد.»

«کسی که journalctl، syscalls و network stack را می‌شناسد، مشکلات پیچیدهٔ production را سریع‌تر حل می‌کند.»

وقتی به گذشته نگاه می‌کنم، می‌بینم ریشه زیست من در کتاب‌هایی است که خوانده‌ام؛ کتاب‌هایی که با آن‌ها گریه کرده‌ام، جنگیده‌ام، و فهمیده‌ام. ماه‌ها درگیر معنای رفتار انسان‌ها بوده‌ام و هر بار لایه‌ای تازه از جهان و از خودم آشکار شده است. از «بال‌های شکسته» و «سینوهه» تا افلاطون و نیچه، از اوشو تا تفکر سیستمی، ذهن هولوگرافیک و حتی ژول ورنِ و ... کودکی‌هایم؛ همه این‌ها دوستان واقعی من بوده‌اند—دوستانی که چیزی به من افزودند، نه اینکه چیزی از من کم کنند.

تلخی جایی آغاز می‌شود که جستجوگری تو را نه به چشم کنجکاوی، بلکه به چشم غرابت و جنون می‌بینند. اندوه زمانی شکل می‌گیرد که ناچار می‌شوی حرفت را فیلتر کنی، نه از سر نادانی، بلکه برای اینکه کسی از دانشت نرنجد. («برای اینکه تصور نکنند فهم تو تهدیدی برایشان است.»
) اما حقیقت این است: رنج جستجو کردن، بهای رشد است. تفاوت ما با جوامعی مثل ژاپن در همین فاصله میان «جستجوگری» و «پذیرش جستجو» نهفته است.

و با همه این‌ها، هنوز هم باور دارم کتاب‌ها بهترین همراهانم بوده‌اند؛ صبور، بی‌توقع و راستگوتر از هر انسانی که دیده‌ام.

کودک‌وار زیستن و معنای اصیل زندگی

انسان مدرن، درگیر شبکه‌ای از مسئولیت‌ها، انتظارات اجتماعی و فشارهای روانی است. زندگی روزمره غالباً ما را از تجربه لحظه حال و شگفتی‌های ساده دور می‌کند. در این میان، مفهوم «کودک‌وار زیستن» به معنای بازگرداندن آن بخش از روح انسان است که هنوز با کنجکاوی، بازیگوشی و حضور کامل در لحظه زندگی می‌کند.

۱. کودک‌وار زیستن چیست؟

کودک‌وار زیستن به معنای بی‌توجهی به مسئولیت‌ها نیست. بلکه نوعی نگرش است که شامل این ویژگی‌هاست:

کنجکاوی خالص: کودک همیشه در پی کشف جهان است، بدون پیش‌فرض و تعصب.

حضور در لحظه: کودکان غرق در تجربه حال هستند و آینده یا گذشته بار روانی‌شان نمی‌شود.

قدرت شگفت‌زدگی: کوچک‌ترین چیزها می‌تواند جرقه‌ای برای لذت و یادگیری باشد.

بی‌پیرایگی و صداقت: کودک بی‌ریا و صادق است، هیجاناتش را سرکوب نمی‌کند.


۲. چرا اصالت زندگی با کودک‌وار زیستن مرتبط است؟

اصالت زندگی به تجربه‌ای گفته می‌شود که در آن انسان با خودش و جهان پیرامونش صادق است و زندگی را به شکلی عمیق و معنا‌دار تجربه می‌کند. ویژگی‌های کودکانه مانند کنجکاوی و حضور در لحظه، امکان تجربه اصیل را فراهم می‌کنند:

کاهش فاصله با واقعیت: وقتی با نگاه کودکانه به دنیا می‌نگریم، از قید پیش‌فرض‌ها و قضاوت‌های اجتماعی آزاد می‌شویم.

بازسازی شادی و انرژی: بازی، خنده و کشف ساده، انرژی روانی و انگیزه انسان را تجدید می‌کنند.

ارتباط عمیق با دیگران: بی‌ریایی و صداقت کودکانه، ارتباطات انسانی را واقعی‌تر و عمیق‌تر می‌کند.


۳. چالش‌ها و سوءتفاهم‌ها

یک سوءتفاهم رایج این است که کودک‌وار زیستن یعنی فرار از مسئولیت‌ها یا نادیده گرفتن واقعیت. این برداشت نادرست است. اصالت زندگی نیازمند تعادل است:

کنجکاوی همراه با خرد: کودک‌وار زیستن نباید ما را از تفکر منطقی و تصمیم‌گیری عاقلانه بازدارد.

شادی همراه با مسئولیت: لذت و بازی نباید به بهای ترک وظایف و مسئولیت‌ها باشد.


۴. راهکارها برای کودک‌وار زیستن در زندگی روزمره

تمرین حضور کامل: مدیتیشن و تمرین ذهن‌آگاهی می‌تواند کمک کند در لحظه زندگی کنیم.

جستجوی شگفتی‌ها: هر روز چیز جدیدی کشف کنید، حتی در کارهای ساده.

بیان آزادانه احساسات: بدون سانسور یا قضاوت، احساسات خود را تجربه کنید.

بازی و خلاقیت: هنر، موسیقی، نوشتن یا بازی‌های فکری را جدی بگیرید.


نتیجه‌گیری

کودک‌وار زیستن، نه نادانی است و نه فرار از مسئولیت، بلکه بازگشت به بخش اصیل انسانی است که درگیر جهان بیرونی نشده و تجربه زندگی را با خلوص، کنجکاوی و حضور در لحظه می‌چشد. این نگرش، کلید دستیابی به زندگی اصیل، معنا‌دار و سرشار از انرژی و شگفتی است.

Most organizations are running in both worlds: they have modern, cloud-native applications in containers, and critical, often mission-critical, systems in virtual machines (VMs).The reality is that running two separate virtualization stacks creates silos, complexity, and unnecessary operational cost – what can be called the complexity tax.
