Right Model, Right Job: A Daily AI Digest with Jev and Claude at 1/10th the Cost
I built a daily AI digest using Jev to classify posts and Claude to summarize the best ones—for about four cents a day. This post walks through the architecture, measured cost savings, quality checks, and practical trade-offs of scheduling the workflow with GitHub Actions and Claude Code routines.Public Videos: Reliability Theory

LIU023: Wendell Odom – The Man Who Wrote THE Book
Renowned Cisco Press author Wendell Odom shares how he began writing the definitive guide for the CCNA exam. Alexis, Kevin, and Wendell discuss the balance between practical, on-the-job experience and certification study habits. Wendell also reflects on his career as well as the creation of his YouTube channel, Network Upskill. Episode Links: Watch this episode... Read more »How a GPU Actually Connects to the Network
This article discusses essential aspects of data center networking for AI, emphasizing the unique communication dynamics between GPUs. It highlights the importance of PCIe bus architecture, NUMA locality, and NVLink technology in optimizing performance. The design strategy of one NIC per GPU and the use of SmartNICs in multi-tenant environments are also explored.

Using Syslog in netlab Labs
netlab release 26.09 added support for Syslog clients and servers. We implemented the clients on numerous platforms; the only Syslog server implementation is the dnsmasq container.
Adding Syslog to a netlab lab is (almost) trivial:
- You have to (re)build the dnsmasq container with the netlab clab build dnsmasq command to add rsyslogd to the container image
- When you add a dnsmasq node to a lab, it automatically starts a Syslog server
- The Syslog client is enabled on other nodes (or globally) with the services.syslog.server setting.
Film Fantasi Akar Pohon Planet: Hiburan Kota dalam Akar Raksasa
Dalam perkembangan dunia hiburan saat ini, film fantasi dengan konsep unik dan imajinatif semakin diminati oleh penonton global. Salah satu tema yang sedang menjadi perbincangan hangat dan menarik perhatian adalah penggambaran “akar pohon planet” yang membentuk sebuah kota berdiameter ribuan kilometer. Film fantasi dengan latar semacam ini tidak hanya menawarkan visual spektakuler, tetapi juga menantang imajinasi dan pemikiran tentang alam semesta, kehidupan, serta hubungan manusia dengan alam semesta di masa depan.
Konsep Akar Pohon Planet dalam Dunia Film Fantasi
Akar pohon planet menjadi fokus utama dalam sejumlah film fantasi terbaru yang dirilis dan sedang dalam tahap produksi saat ini. Ide dasar yang menginspirasi konsep ini adalah keberadaan sebuah planet yang pohonnya tidak biasa, dengan sistem akar raksasa yang membentang luas hingga ribuan kilometer. Sistem akar tersebut bukan hanya menempel ke tanah, melainkan membentuk ruang hidup yang sangat luas, memungkinkan kota atau bahkan peradaban tercipta di dalamnya.
Berbeda dengan konsep kota futuristik tradisional yang berdiri di atas permukaan atau di bawah tanah, kota dalam akar pohon planet menggabungkan unsur alam dan arsitektur fiksi ilmiah. Kota-kota ini berkembang di dalam akar raksasa yang menyediakan segala kebutuhan ekologis sekaligus menjadi benteng alami dari ancaman luar. Dalam konteks hiburan saat ini, film Continue reading
Negara Internasional Kembangkan Mega-Proyek Pemulihan Pegunungan Terbakar dengan Drone
Pemulihan lingkungan, khususnya di daerah pegunungan terbakar, menjadi fokus utama sejumlah negara di dunia saat ini. Fenomena kebakaran hutan dan pegunungan yang meningkat tajam menyebabkan kerusakan ekosistem yang luas, sehingga menggerakkan komunitas internasional untuk mencari solusi inovatif dan efektif. Salah satu teknologi terbaru yang sedang dikembangkan adalah penggunaan drone penebar mikroorganisme sebagai bagian dari mega-proyek pemulihan pegunungan terbakar. Artikel ini mengupas secara menyeluruh perkembangan teknologi tersebut dan negara-negara yang menjadi pelopor dalam implementasinya.
Peran Teknologi Drone dalam Pemulihan Pegunungan Terbakar
Di tengah tantangan besar yang dihadapi akibat kebakaran hutan dan gunung, teknologi drone muncul sebagai solusi revolusioner. Drone penebar mikroorganisme mampu menjangkau area yang sulit diakses manusia secara cepat dan akurat, membawa benih-benih mikroorganisme yang bermanfaat untuk mempercepat proses rehabilitasi tanah dan vegetasi.
Mikroorganisme yang digunakan merupakan hasil rekayasa bioteknologi modern, seperti bakteri dan jamur yang mampu meningkatkan kesuburan tanah, memperbaiki struktur tanah yang rusak, dan mendorong pertumbuhan tanaman secara alami. Dengan metode penebaran yang presisi menggunakan drone, proyek ini menjanjikan efisiensi tinggi dalam memperbaiki ekosistem yang rusak akibat kebakaran.
Negara yang Memimpin Mega-Proyek Pemulihan Pegunungan Terbakar Menggunakan Drone
Beberapa negara dengan ekosistem pegunungan yang rentan terhadap kebakaran telah mengambil langkah strategis dalam mengaplikasikan drone penebar mikroorganisme, di antaranya Continue reading
D2DO314: Backups SaaS – Safety as a Service
Ned and Kyler talk with Jim Jones about data protection, backups, and security in the age of hybrid cloud and AI. They explore the operational challenges of integrating automated AI agents into enterprise workflows, the need for proper permission scoping, immutable backups, and data security posture management (DSPM). AdSpot Sponsor: Gartner The Gartner IT Infrastructure... Read more »The Clearinghouse For AI Agents Has A Blind Spot
Jamin Ball’s recent piece, “Systems of Record Won the SaaS Era — Clearinghouses Will Win the Agents Era,” is the cleanest articulation I’ve seen of where the durable moat goes next. His argument is simple and, I think, correct: the SaaS era rewarded whoever owned the system of record, and the agent era will reward whoever owns the clearinghouse. This is a new seat that sits between mutually-distrusting agents and decides which one is cleared to act, on what data, with what limits, and can prove what happened after the fact. The lock-in moves from your data to your permissions. The source-of-truth era becomes the source-of-permission era.
I agree with all of it. Governance has graduated from a compliance checkbox at the end of the sales cycle to the first question a CIO asks. Once agents act autonomously and eventually spend real money, “is the model good?” stops being interesting now that every model is good enough and “can I see what every agent did, set policy on what it can touch, and prove it to my auditors?” becomes the whole conversation. That seat is strategic real estate. Whoever holds it is hard to dislodge.
The OSPF MTU Mismatch Saga
The OSPF is stuck in database exchange state symptom is probably familiar to every networking engineer who ever had to pass a certification exam. It’s caused by the MTU mismatch between adjacent OSPF routers.
The recent (unexpected) trip into the how crazy is it to declare your interface MTU to be zero wonderland uncovered way more than I ever wanted to know about this arcane topic. Here are a few highlights (thanks a million to Aleksey Popov for researching this topic and posting information here, here, and here).

After a long journey, we finally we got to the final scenario in my ITNOG10 Segment Routing workshop: EVPN services over an SR-MPLS core.
I used the same lab topology as in the previous services-focused scenarios blog post, replacing two PE-to-host subnets with a stretched VLAN.

Ansible Installation
It has been over 5 years since I wasted far too much of my life on my Ansible build fabric pet project. I got it doing what I set out to do, but there was so much Python fudging under the hood I figured I may as well move away from Ansible and go all in on Python (and Nornir). I thought it was high time to give Ansible another go and see if it has got any less painful.
