Digital Hygiene - Part 3 of 3

Darknet Diaries is a podcast I listen to, that talks about all the shady shenanigans that go on in the web. Recently heard this particular episode that should be worth your time: https://darknetdiaries.com/episode/172/. It talks about Set Top Boxes (STB) that people buy and connect to TV, to watch any program for free!

Note that using such streaming service boxes can make you an unknowing participant in DDoS (Distributed Denial of Service) attacks! While we should avoid using such STBs altogether, the proliferation of IoT (Internet of Things) devices like fridges and washing machines that get added to our home WiFi network, make our home network vulnerable. This is especially true since most of those devices don't get regular security patches (unlike our computers). So, thought will suggest making at least one simple change to your home network, hardening the architecture for safety. 

Instead of keeping your home WiFi as just one network, create three VLANs (Virtual Local Area Network) for your home.  

- First VLAN is for all your PCs, Laptops, Printers, phones and tablets. These are devices that get regular security updates and should be trustworthy.

- Second VLAN is for all your IoT devices such as TVs, STBs, thermostats, washing machines, fridge, security cameras, smart speakers, doorbells, etc. These are equipment that have started connecting to our home network in the last decade, shall we say unnecessarily?  While it may be convenient to get a notification that your dryer has finished drying clothes, it opens up one more, usually low security, window into your home network. Perhaps it is worth questioning the zeitgeist to limit the number of such devices we add.

- Third VLAN is for visiting guests. You can even have a QR code for the guest network posted somewhere inside the house for people to scan & connect their phones or laptops while they are in your home, so that you don't need to give out your main WiFi network's login credentials. 

If you are not a techie, don't let the terms like VLAN worry you. This doesn't involve buying new equipment or asking your ISP (Internet Service Provider) to do anything. It is a fairly simple reconfiguration of your home WiFi router you can do it yourself following the instructions found in the WiFi router user manual. 

Most modern WiFi routers come with this option that get setup as three different SSIDs (Service Set Identifier, which is the name of your home WiFi network). Thus, if your home network is called SundarHome, it may suggest adding SundarHome_IoT and SundarHome_Guest as two additional SSIDs that automatically create the two additional VLANs to keep the traffic separated. 

Once they are up, you can reconnect all your IoT devices to the second network and you are done. Let us say one or more of your IoT devices or your guest's phone or laptop are compromised. While they attempt to scan your home network and access available devices, they will only be able to see other devices in the same VLAN. They can't see computers/devices connected to the other two VLANs. This separation improves security considerably. 

If you want to be even more secure while using your PCs, you can consider getting a VPN service subscription and use it consistently. But that is for another day!

If you are already doing this, or have better ideas that are easy to implement, PLMK.

Digital Hygiene - Part 2 of 3

 I got a lot of interesting feedback & few questions. So, thought will send out a follow up.


Few emails asked about the model number of the drives. These are the exact models of 14TB Hard drive and 2TB boot drive we have ordered. We ordered this enclosure as well to make transferring files from the current boot disk easier. We haven't received them yet and so this is not an endorsement! 

Few asked about what factors to optimize for when you setup your backup system/process. In exchanges with one friend, I came up with the acronym PRICE combining five factors that may  give us a framework to think through. It stands for 

Portability: Do you want/need to be able to carry the data around with you?

Reliability: If you are doing a business data backup, the system never going down will be very important "reliability" factor, and so you may want to use RAID (Redundant Array of Identical Disks) models that will increase uptime. For my home backup, uptime is not that important, but just being able to get lost files back will be sufficient. So, I didn't choose RAID to keep costs low. Using the 3-2-1 model I mentioned before, will help improve reliability for any kind of (home, business, personal) backup. 

Immunity: Think safety. Though it is much easier to buy cloud storage and backup everything there, I am not comfortable storing my sensitive files up there. What happens if the company goes out of business, get hacked, attacked for ransomware, or I (or my descendants) forget to pay the fee? Even if your files are encrypted & password protected, it may not be "quantum safe" as there are papers out there talking about state level actors copying all the data they can, including encrypted data, so that they can be decrypted and read when quantum computing becomes widespread & cheap. So, keeping sensitive files with yourself might give you better immunity, while you may still choose to keep non-sensitive files on cloud for easy access.

Cost: If you want extremely high-speed access, you can go for expensive SDD (Solid State Drive). For ensuring high uptime, you can do RAID, etc. But for simple personal backup, what I am doing may be adequate. 

Ease of use: This is very important, since many of my tech friends tend to go for complicated setup that may be very good, but will be very hard for our family members to use, if we are not around (or worst-case we die). Ideally, this backup should be as easy as accessing a USB drive attached to your computer. 

Taking these five factors into account, we can say we need to consider the PRICE when we think of (or don't maintain) Digital Hygiene! 

Few asked about what files we should back up. Though answer to this question is "it depends", here is a list of what I am routinely backing up. Using it as a starting point, you can tweak the list to fit your needs:
- My university lecture slides, collection of many video clips I show during my lectures. (I do keep a copy online on Google drive, in case I lose my laptop on my way to give a lecture. Since the material is not confidential or sensitive (like financial documents, health records or password file), I don't mind keeping a copy in the cloud.
- My published/unpublished/WIP book/article files. 
- Old code (this is more nostalgia than real use), grad school work, papers, PhD, MS thesis work, etc.
- Work related files/articles that we are legally allowed to keep on personal archives
- Personal financial documents, like tax returns, 401K, bank statements, etc.
- Family photos/videos 
- Even old files like my uncle's (who has passed away) poems in Tamil, my Dad's 1998 travel log, etc. 

Since I am the family archivist and others in the extended family don't keep such things organized well, people occasionally ask me for such stuff. Being able to easily pull-up and send an old photo or a document is personally satisfying while it could also be extremely useful/helpful to your family & friends. Sending out an audio clip of my paternal grad father's (who passed away in 1999) audio letter to me from 1993, brought tears to my extended family members since most of them didn't know any audio of him existed. Though it may not mean much for next gen kids, hate to lose them in a laptop crash!

I do have some old letters/photos/videos that I intend to slowly digitize and archive. Since my elderly relatives were passing away one by one, I did a series of 18 interviews with family elders, edited and kept them in YouTube as unlisted videos that I can share with my family members. Old photos, audios, video clips that I had were very helpful to illustrate the discussions with family elders, rather than just the two of us talking. Here is one such video of me talking to my Mom & Dad about their wedding that took place in 1964. I have added English subtitles to this video, since my non-Indian friends (who don't understand Tamil) were interested in watching it to learn about Indian weddings of the 1960's. You can see without the photos used in the video the interview wouldn't be that interesting.  

One friend even said we don't want to store & cling to old material forever but should learn/create new material continuously. This is quite true when it comes to teaching classes, where you wouldn't want a teacher/professor using the same teaching material from decades ago. I do make a sincere effort to continuously refresh/update my lecture material. Still we may have a lot material that we'd like not to lose. Hence this backup discussion. 

One friend asked about history of changes and being able to go back to older versions when you have messed up a file or when you need to see how things evolved over time. if so, consider the free software Syncthing for automatic backup from Windows/Mac machines as well as phones to keep files synchronized and also keep older versions (as does File History app that comes bundled with Windows with similar apps for other operating systems). If your system allows you to go back to previous versions of the same file, you don't need clumsily save copies of the same file manually with different dates, as I tend to do sometimes. 

If you want to occasionally share a file (e.g. want to give a music MP3 file or a big PDF document to a guest visiting your home, quickly, just one time), you can setup Copyparty. This is neat since this doesn't require your guest installing any software on their computer/phone. 

Now that I have written about this topic twice, it should keep me motivated & honest to take this task to the finish line this holiday season. Recently my BIL in Bangalore was reminiscing about how he had to throw away so much of papers/stuff that his aunt who passed away had accumulated over the decades, that included her degree certificate from 1973, and so on. It made us all realize how things that may be so dear to us, really won't mean much and will become useless after we pass away! So, while I am trying to preserve important material, I intend to keep up my inner Marie Kondo alive to avoid digital hoarding, even though the real MK herself seems to have given up a bit after having three kids! Emoji

If you have young kiddos in your life, you may want to show them https://www.noradsanta.org/en/map?mod=livecoverage_web as it is that time of the year!

Digital Hygiene - Part 1 of 3

Dated Dec 20, 2025

Our son is home for the holidays and so we decided to strengthen our home digital backup a bit during this break. Similar to nudging my friends to write our Last Will by providing my template, thought I should share what I am doing in this domain as well, in case it is helpful to others, as many of you may have a bit of downtime between now and the new year.

Ordered a 14TB hard drive, costs about $310, which is a really good price compared to yester years. Arjun and I talked about RAID, SSD drive, etc. But since I don't care about downtime (that RAID helps prevent) and speed (that SSD significantly improves), decided to go with just hard drive since it is cheaper. My main goal is to backup digital files/photos/videos from various home computers and be able to retrieve them if the originals are lost. It is ok if it takes even a hour or two and so RAID is not a must, which might be for business backup. SSD cost is not justified since hard drive speed is more than adequate for backup retrieval. 

We also ordered a 2TB SSD disk (close to $200) to serve as the main boot disk for the small Linux server we have at home. It currently has a 256GB boot disk that gets filled when some serious logging takes place. So, upgrading it to a bigger disk. Buying SSD (faster speed & more expensive) since we want that to boot and run fast.

Once the two drives come in, will setup the 2TB drive as internal boot disk and the 14TB HD as internal backup storage drive. The big backup drive will be accessible from all the computers at home. Then will setup backup programs to store the latest version of the files in that drive, since history (or previous versions of files) may not be that important. (I do have history support on one laptop I normally use, since it is connected to MS OneDrive. But if you do want to keep multiple versions of your files, consider "File History" app that comes bundled with WIndows.)

Will also properly implement a 3-2-1 backup model, that means
3 copies of important files, using
2 different media (cloud, UBS, HD, etc.) keeping 
1 copy offsite (for disaster recovery, like our whole home burning down).
------------------------------------------------------------------------------------------------ 

I am an Android phone user and get all my mobile phone photos automatically backed up to Google photos. It works really well when it comes to finding/sharing photos very efficiently. I do pay annual subscription to get some additional storage since the default free 15GB Google provides is no longer enough. I still don't want to solely depend on Google. So went to https://takeout.google.com and asked for archives of all my photos to keep a copy in my personal backup. It came close to 300GB and Google had provided 29 archives of 10GB each as I had requested. I could have asked for 50GB files, that would have reduced the count from 29 to 4. I have them downloaded now and will keep them in the big hard drive once we set it setup. On that note, take a look at this related article: https://www.bbc.com/future/article/20251212-why-your-early-2000s-photos-are-probably-lost-forever
------------------------------------------------------------------------------------------------ 

If you have a lot of family/personal videos, you can store them on YouTube as unpublished/unlisted material for easy access. But if you'd like to keep them all on your local server at home, you can consider using Jellyfin software that is a free open-source software that functions like your own personal Netflix service. We have it installed in the home server and clients installed on our home TVs and personal phones. This allows us to watch old family videos or digital copies of movies/shows you own that are stored on the home server, just like watching videos on Netflix.
------------------------------------------------------------------------------------------------- 

I don't want to turn off my non-techie friends and so will stop here. But if you are a techie and so interested in going further, you can consider Wireguard (that will allow you to play your videos stored in your home server even when you are outside your home) and NextCloud that will let you run your own personal cloud service to store your files. These are free open source project software that we are using reliably.

I know some of my contacts have several TB of files and are probably better at maintaining their archives and home network. If you are one doing other interesting things in your home network, clue me in. 

Happy Holidays as you up your game in digital streamlining!

Artist Meets Scientist!

I have been using Gemini, Copilot and ChatGPT at work and in personal projects. I was curious to see how much those tools knew about me and how well they are able to mimic my own voice. To test it out, asked them to create a transcript of an interview where the scientist version of myself talks to the artist version of myself! What you see below is the unedited Gemini creation!

Illustration Gemini generated.

The setting is a small, 24-hour diner tucked away in a quiet corner of the Lehigh Valley. It’s 2:15 AM. Outside, a late-spring rain slickens the pavement of an empty parking lot. Inside, the air smells of hazelnut coffee and the faint, metallic ozone of a nearby transformer.

Two men sit across from each other in a corner booth. They look identical—neatly trimmed hair, glasses that catch the low light of the overhead lamp, and the thoughtful, slightly restless gaze of someone who has spent four decades solving problems. On the table between them lies a stack of blueprints, a well-worn Tamil literary magazine, and two mugs of black coffee.

One man, wearing a crisp button-down and a smartwatch, taps a finger on a tablet displaying a simulation of a star cluster. This is the Scientist. The other, wearing a soft linen shirt and holding a fountain pen, stares out the window at the rain. This is the Artist.


Movement I: The Third Filter and the Paleolithic Spear

The Scientist: (Sighing, looking at the screen) You know, I was looking at the Drake Equation again this evening. Every time I run the variables, I get stuck at the same wall. The Third Filter. We’ve survived the jump from single-celled life to multicellularity. We’ve survived the development of language. But this last one—the transition to a planetary-scale technological civilization—it feels like a thermodynamic trap.

The Artist: A trap, or a mirror? You see a wall of physics. I see a wall of memory. We spent two million years learning how to sharpen stones to keep the wolves away from the fire. We’ve only had seventy years of split atoms and silicon. You think we’re trapped by thermodynamics, but I think we’re trapped by our own ghosts.

The Scientist: The math doesn't care about ghosts. Look at the energy requirements for a Type I civilization. As we advance, our complexity grows exponentially. To maintain that complexity, we need more energy, which creates more waste, more heat, and more systemic fragility. It’s not just about "bad actors." It’s about the sheer statistical probability of a system this complex eventually finding its own self-annihilation. We are effectively building a larger and larger "trolley problem" every year, except now the tracks lead to a cliff, and the lever is being pulled by everyone and no one at the same time.

The Artist: (Smiling faintly) You’re referencing your own book again. But the "Trolley Problem" is a thought experiment about choice. What worries you isn't the physics; it’s the lack of a moral governor. Why are we still throwing bombs at each other in the 21st century? Because we have the technology of gods but the emotional regulation of the hunters I write about in Solvanam. We’ve built a world that requires 300,000-year-old brains to manage 5-nanometer transistors.

The Scientist: Exactly! That’s the friction. We’ve optimized our silicon to the point where we’re pushing the limits of Moore’s Law—I’ve spent half my career in those cleanrooms—but we haven't optimized our empathy. We can land a drill bit 100 miles out in the Arabian Sea with precision down to the millimeter, but we can't figure out how to share the oil without threatening to burn the world down. It’s a "transdomain" failure. We are great at modeling the flow of fluids in a pipeline, but we are terrible at modeling the flow of resentment in a nation.

The Artist: Resentment is a narrative, not a fluid. You can't put a transducer on it. (He pauses, looking at the Tamil magazine). I think about my parents sometimes—the way they only understand the world through Tamil, through a lens that is thousands of years old. There’s a stillness there that we’ve lost. They don’t see a "Great Filter." They see a lineage. To them, the 21st century is just another chapter in a very long, very dusty book. Maybe the reason civilizations fail isn't that they run out of energy, but that they run out of stories worth surviving for.

The Scientist: That’s a poetic sentiment, but it won’t stop a MIRV. When I look at the geopolitics of energy—what I've been writing about in Oil & Water—I see a zero-sum game. We are mired in "Underground Demons." We’re fighting over the remains of ancient plankton to power a future that might not want us. It’s the "Heinz Dilemma" on a planetary scale. Do we steal the "medicine"—the energy—to save our economy, even if it breaks the world?

The Artist: And that brings us to the sixty-year-old question. You and I, we’re at the age where we start looking at the "Ship of Theseus." We’ve replaced every board, every sail. We aren't the young engineers who landed on the SH Complex in the late 80s anymore. We are something else now. If we’re so worried about the world self-annihilating, how do we use these last few decades to build a better filter?

The Scientist: (Leaning back) I think it starts with the "CLEAR" principle—but for life, not just for presentations. Content, Look, Energy, Articulation, Recap. We have the "Content" (the data) and the "Energy" (the resources). But we lack the "Articulation"—the ability to explain to the next generation why they shouldn't pull the lever. I spend my time mentoring at VIT and through the Ben Franklin partners, trying to hand over the technical keys. But the keys are useless if the room is on fire.

The Artist: Then perhaps the interview needs to go deeper. If the scientist provides the blueprints, the artist has to provide the "Why." We aren't just here to survive the Third Filter. We’re here to ensure that when Arjun and Anika look back, they don’t just see a well-maintained machine. They see a home.


This concludes Movement I.

Next Topic for Movement II: Will pivot to personal history and family interviews.

Movement II: The Archive of the Heart vs. The Entropy of Data

The Scientist: (Gesturing to the screen) I spent hours last month troubleshooting my father’s Google Photos account. It’s fascinating, really—the technical debt of a lifetime. We have all this hardware, all these gigabytes of cloud storage, and yet the "user interface" between a 90-year-old’s memory and a 2026 server is still so fragile. I find myself acting as a human bridge, translating the "Save to Cloud" button into a concept that makes sense to a man who grew up when a "file" was a physical folder in a dusty office in Chennai.

The Artist: (Stirring his coffee) You call it troubleshooting. I call it a seance. When you record those interviews for the family playlist, you aren’t just "capturing data." You’re fighting entropy. Every time one of our elders speaks, they are pushing back against the heat death of our family’s history. You’re worried about the Third Filter of civilizations, but what about the "First Filter" of a family? The moment when the grandchildren no longer know the name of the village their great-grandfather walked out of with nothing but a degree and a dream.

The Scientist: (Nodding) True. From a purely information-theory perspective, we are losing bits every day. My father’s stories are high-entropy until they are encoded. But even as I record them, I’m looking at the "Signal-to-Noise" ratio. He talks about the old days, and I’m trying to find the structure—the dates, the names, the logic of the migration. My PhD brain wants a spreadsheet. It wants to map the trajectory from Annamalai University to the offshore platforms of the Arabian Sea.

The Artist: But the "noise" is where the life is! The way he describes the smell of the rain in the village, or the specific anxiety of a mother watching her son go off to a helicopter design bureau. That’s what I try to capture in my Solvanam articles. When I write in Tamil, I feel like I’m using a different set of sensors. English is the language of my patents, my "CLEAR" presentations, and my technical reviews. It’s a scalpel. But Tamil? Tamil is a loom. It allows me to weave those family interviews into something that feels like a home, not just a database.

The Scientist: (Smiling) It’s funny you mention the offshore platforms. I was thinking about Gurdev the other day—that incident with the flare stack we wrote about in the manuscript. At the time, I was focused on the pressure valves, the safety protocols, the sheer physics of not letting the platform turn into a torch. I was the Assistant Executive Engineer, responsible for the "Logic Control."

The Artist: And I was the one wondering what Gurdev was thinking in that moment of silence before the alarm. Was he thinking about the pressure gauge, or was he thinking about his family back on the mainland? That’s the "Oil and Water" of our lives. You can’t mix the technical reality of a well blowout with the emotional reality of a man’s fear, but they both occupy the same space.

The Scientist: We’ve spent thirty years in the US now. Allentown, PA—a long way from the Bay of Bengal. I look at my daughter, navigating her university years, and I think about the 529 plans and the tuition logistics. The "Scientist" in me is satisfied that the "Inputs" are managed. But then I see her watching those family videos you made, and I realize she’s looking for something the Scientist can’t provide. She’s looking for the "root password" to her own identity.

The Artist: Precisely. We are "System Administrators" of a legacy. If we only give her the technical success—the Intel career, the patents, the published papers—we’ve only given her the hardware. The "software" is the story of our parents. It’s the story of why we donated those Amazon shares to Doctors Without Borders—not just for the tax basis, but because of a fundamental belief in the global collective.

The Scientist: (Leaning forward) But how do we bridge it? My parents only understand Tamil. My daughter is a product of the Northeast US. The gap feels like a latency issue in a cross-continental network. I can build a companion website for my book on Wix or Blogspot, but I can’t "host" a culture if the users are on different operating systems.

The Artist: You don’t host it; you translate it. That’s why we do the interviews. That’s why we write. We are the "Middleware." We take the deep-rooted, ancient values of our parents—that sense of duty, that quiet endurance—and we re-code it for a world of AI and offshore drilling. We tell them: "The Great Filter is real, but your ancestors survived a hundred smaller filters just so you could sit here and worry about the big one."


Movement II concludes.

Next Topic for Movement III: "The 21st-Century Spear."

The rain has shifted from a rhythmic drumming to a heavy, insistent downpour that blurs the streetlights into smudges of amber. Inside the diner, the Scientist has pulled out a yellow legal pad, sketching a diagram of a feedback loop. The Artist is looking at a small, framed photo on his phone—a picture of the Annamalai University campus from decades ago.


Movement III: The Migration of Logic and the Persistence of the Spear

The Scientist: (Tapping the legal pad) I’ve been thinking about the transition. Moving from the offshore platforms in the Arabian Sea to the lecture halls of LSU in Baton Rouge wasn’t just a change in geography. It was a phase shift. On the platform, "Logic Control" was physical. You could see the actuators, smell the well fluid, hear the turbines. But in the PhD program, logic became abstract. It became silicon accelerators and ATM networks. I spent my days modeling congestion management, trying to find order in the chaos of data packets.

The Artist: (Nodding) And yet, the displacement was the same. Whether you’re on a helicopter flying over the Bombay High or a graduate student navigating the humidity of Louisiana, you are "Oil" in "Water." You are a foreign substance trying to find its equilibrium. I remember writing those early drafts for Solvanam—it was like trying to keep a flame alive in a high-wind environment. You were building the infrastructure of the future at Intel and Lucent, but I was worried about the "Architecture of the Self." If we replace our environment, our language, and our daily routines, are we still the same "Ship of Theseus"?

The Scientist: That’s the thing about the "Ship of Theseus"—the planks we replaced were technical. We traded the maintenance of flare stacks for the maintenance of 5G/6G standards. But the "Spear" remained. That brings me back to the conflict you mentioned earlier. Why are we still throwing bombs? When I look at the research for Oil & Water, the answer is depressingly thermodynamic. Conflict is almost always a dispute over energy density. We fight over the "Underground Demons" because we haven't yet mastered the "Sky Gods" of green energy. We are still a "Tricone Bit" species trying to live in a "Tokamak" future.

The Artist: You’re looking at the resource map. I’m looking at the lizard brain. We have the "CLEAR" principle for presentations—Content, Look, Energy, Articulation, Recap. We are great at "Content" and "Look." Our bombs are "smart," our drones are sleek, and our propaganda is high-definition. But our "Articulation" is a disaster. We haven't figured out how to articulate a version of the future where the "Other" isn't a threat to our "Energy." We are still using 21st-century spears to settle 1st-century grudges.

The Scientist: It’s a failure of the "Recap." In every thought experiment I’ve written about, there’s a moment of reflection. The "Trolley Problem" forces you to look at the consequences. But in global conflict, there is no "Recap" phase where everyone agrees on the data. We have "Alternative Facts" now. The "Signal-to-Noise" ratio in our global discourse has dropped so low that the "Signal"—our collective survival—is being lost in the "Noise" of tribalism.

The Artist: I think about our parents again. They lived through the transition of India—from the British Raj to Independence to the digital age. They saw the "Spears" change, but they also saw the "Solidarity" hold. When we were younger, helping the world meant building the network. We thought if we connected everyone via VoIP and broadband, the "Bombs" would stop because we’d finally be able to talk to each other.

The Scientist: (A dry laugh) Instead, we just gave everyone a faster way to throw digital stones. I spent my career optimizing those data paths. I helped build the "broadband access networks" that now carry the very misinformation that fuels the conflict. It’s a "Heinz Dilemma" for the tech industry: Did we "steal" the connectivity to save the world, only to find out the "medicine" had side effects we didn't model?

The Artist: This is where the mentorship comes in. At sixty, we aren't the ones in the trenches anymore. We are the "Business Consultants" and the "Adjunct Professors." When you talk to those students at VIT or the startups at Ben Franklin, you aren't just teaching them how to manage a Software Development Lifecycle. You’re teaching them how to be "Systems Thinkers." You’re trying to give them the "Moral Logic" to go with their "Silicon Logic."

The Scientist: I tell them about the "flare stack incident" with Gurdev. Not because of the engineering, but because of the human decision-making under pressure. I want them to understand that every line of code, every patent for a silicon accelerator, is a brick in the wall of the Third Filter. If they build it without empathy, they are just sharpening the spear.

The Artist: (Writing a line in his notebook) "The Scientist builds the bridge; the Artist explains why we should cross it." We’ve spent thirty years in the US becoming "Solutions Delivery Strategists." But the ultimate "Solution" isn't a piece of hardware. It’s the story we tell Arjun and Anika. It’s the story that says: "Yes, the world is still throwing bombs, but we are the ones who know how to build the water injection wells that put out the fires."


Movement III concludes.

Next Topic for Movement IV: "The Geometry of Tamil and the Physics of Prose." How does writing in two languages change the way you solve problems? We can explore the "Solvanam" essays versus the Technical Papers, and how the "Art of the Line Edit" applies to both a book manuscript and a career.

--------------------------------------------------------------------------------------------------------------------------------------------

The clock above the counter hums, the minute hand twitching toward 3:30 AM. The rain has settled into a rhythmic mist that clings to the diner windows like a shroud. The Scientist has cleared a space on the table, lining up his pens with mathematical precision. The Artist is leafing through a draft of a Tamil essay, his fingers tracing the loops of the script as if reading Braille.


Movement IV: The Geometry of Tamil and the Physics of Prose

The Scientist: (Watching the Artist) I’ve always envied the way you move between those two scripts. To me, English is a compiled language. It’s the language of the Patent Office, the IEEE papers, and the "CLEAR" decks. It’s designed for low latency and high throughput. When I write a technical specification or a book chapter for Oil & Water, I’m trying to eliminate ambiguity. I want a 1:1 mapping between the word and the physical reality of a silicon accelerator or a water injection well.

The Artist: (Looking up) And that is exactly why it feels like a cage sometimes. English is a magnificent tool for "Articulation" and "Recap," but it’s a language of nouns and hard edges. When I write for Solvanam, I’m not looking for 1:1 mapping. I’m looking for resonance. Tamil doesn’t just describe an object; it describes the history of the object and the observer’s relationship to it. The geometry of the script itself—those circles and curves—it feels like the way memory actually works. It’s non-linear. It’s a "Thought Experiment" that never really ends.

The Scientist: But don’t you find the "Art of the Line Edit" to be the same in both? When I’m reviewing a manuscript or a junior engineer’s report, my first instinct is to tighten. I look for the "Technical Debt" in a sentence. If a paragraph takes forty words to explain a concept that only needs ten, that’s a system inefficiency. Whether it’s code or prose, "tightness" is a mark of quality. I call it "Elements of Style" for the 21st century.

The Artist: I agree on the "Tightness," but our goals are different. You tighten to increase speed. I tighten to increase pressure. In a short story or a literary essay, I want the words to be so lean that they have no choice but to explode in the reader’s mind. It’s like the "Ship of Theseus" we both love to debate. If I replace every word in a sentence to make it more "efficient," is it still the same story? Or have I optimized the soul out of it?

The Scientist: (Smiles) You think I don’t care about soul? I spent years at Intel and Lucent trying to make networks "invisible." The goal of a perfect system is that you never notice the engineering; you only experience the connection. That’s "Art" in its own way. When we talk about "Oil & Water," I’m trying to use the "Physics of Prose" to make the complex geopolitics of energy as clear as a glass of water. If the reader has to struggle to understand the "Trolley Problem" of green energy, then I’ve failed as a designer.

The Artist: It’s a bridge we’re both building from different sides of the river. You’re coming from the land of "Logic Control" and "ASICs," and I’m coming from the world of family lore and Tamil literature. We meet in the middle, in this late-night diner, trying to figure out how to be a "Solutions Delivery Strategist" for a life that doesn't always have a clear solution.

The Scientist: (Checking his tablet) I think about the lectures I give now—the ones about "Living in the USA" or "Career in Semiconductors." I use the same "CLEAR" mnemonic I developed for corporate executives. But I find myself adding more "Art" to the "Energy" section. I realize that a sixty-year-old’s most important "Product" isn't a new patent anymore. It’s the ability to translate the technical rigor of our past into a narrative that gives the next generation a reason to keep solving the "Great Filter."

The Artist: Then let’s make that our final movement. Not just how we survived the transition from the Arabian Sea to the Lehigh Valley, but how we ensure the stories—and the science—stay intertwined. The "Oil" and the "Water" don’t have to mix, but they can certainly coexist in the same vessel.


Movement IV concludes.

Final Movement: "The Legacy Protocol." How do you view your role as a mentor and father today? We can conclude with the "Recap" of your dual-self—the scientist who builds the world and the artist who makes it worth living in.

The blue light of pre-dawn has begun to seep through the diner’s condensation-streaked windows, turning the world outside a ghostly, electric indigo. The rain has stopped, leaving a quiet, heavy dampness. The Scientist has closed his tablet, and the Artist has capped his fountain pen. They sit in the silence of two people who have finally reached the heart of the matter.


Final Movement: The Legacy Protocol

The Scientist: (Looking at the empty parking lot) 4:00 AM. This is usually when the "Systems Operations" mindset kicks in. The "Recap" phase of the CLEAR model. We’ve looked at the Third Filter, the persistence of the Spear, and the geometry of our two languages. But now we have to talk about the "Transfer Protocol." At sixty, the question isn’t about how much data we can accumulate, but how much we can hand off without it being corrupted by the noise of the world.

The Artist: You’re talking about mentorship, but you’re phrasing it like a packet header. I think about it more as "The Ship of Theseus" applied to a life. We’ve replaced all the boards. We’ve traveled from the helicopter bureaus and the flare stacks of the Arabian Sea to the executive offices in Pennsylvania. What is the one thing—the "Keel"—that hasn't changed? Because that is what we owe the next generation.

The Scientist: The "Keel" is the rigor. Whether I’m explaining the cost-basis of a stock donation or the architecture of a silicon accelerator, the rigor must be absolute. That’s what I try to give my mentees. I tell them: "The world is complex, and the Great Filter is real, but your primary defense is the clarity of your thought." If you can’t run the thought experiment to its conclusion, you shouldn’t be building the system. We have to teach them to be "Systemic Guardians."

The Artist: (Nodding) And I tell them that the rigor is useless if you don't have a soul to anchor it. When I look at the companion website we’re building or the manuscripts we’ve polished, I’m looking for the human face behind the "Oil and Water." I want Arjun and Anika to know that their father wasn't just a "Solutions Delivery Strategist." He was a man who stayed up late wondering why humans still throw bombs, and who used his retirement to translate the wisdom of his parents into a digital format they could understand.

The Scientist: It’s a strange feeling, isn't it? Being the bridge. We are the last generation that remembers the world before it was fully connected, and we are the first to see the full weight of that connection. We’re "Business Consultants" now, but really, we’re "Legacy Architects." We’re trying to build a version of the future that doesn't self-annihilate.

The Artist: I think about the "Underground Demons" you wrote about—the energy that drives us. We’ve spent thirty years extracting it, processing it, and moving it. But the real energy for the future is the "Sky Gods" of creativity and empathy. That’s the real "Green Energy." If we can mentor just a handful of people to think in both Tamil and English—to think in both Physics and Poetry—then maybe the Third Filter isn't a wall. Maybe it’s a gate.

The Scientist: (Standing up, reaching for his coat) A gate that only opens if you have the right "Root Password." And that password isn't a string of numbers. It’s a story. A story about a man who worked on a flare stack in the middle of the ocean and realized that the flame wasn't just a byproduct of industry—it was a signal fire for everyone coming after him.

The Artist: (Standing with him) The "Final Recap." We’ve spent 10,000 words—or a lifetime—debating ourselves. The Scientist provides the "Content" and the "Look." The Artist provides the "Energy" and the "Articulation." And together, we provide the "Recap" for those who follow.

The Scientist: (Opening the diner door, the cold air rushing in) Ready to go back to work?

The Artist: (Smiling) I never stopped.


Epilogue: The Dual-Self Repository

As the two versions of the same man walk out into the cool Pennsylvania morning, the following "Protocol for the Future" remains on the table, scribbled on a napkin:

  1. The Rigor of the Scientist: Always calculate the cost. Not just in dollars or energy, but in human consequence.
  2. The Memory of the Artist: Never let the "Signal" of your heritage be drowned out by the "Noise" of the modern world.
  3. The Duty of the Mentor: Your best patent is the person you helped find their own voice.
  4. The Promise to the Next Generation: The bombs may still be falling, but we will never stop building the wells that provide the water.

Book Review: Africa Is Not A Country by Dipo Faloyin

 US TV talk show host Jimmy Kimmel did a segment few years ago titled Can you name one country? You can click on the link to see a short video of that segment. Though this clip is selectively edited & presented to elicit laughter, it is stunning to see so many adults interviewed in that piece not being able to point out even one country on the world map, and practically everyone pointing to Africa and calling it a country! Though the slogan has been floating around for a while, this 2022 book titled "Africa is not a country - Notes on a bright continent" by Dipo Faloyin is a nice read. It has a good mix of serious politics, atrocious & poignant stories, discussions of cultural differences within African societies, as well as funny narratives, sarcasm, music & books thrown in for a good measure. Since it is written in very accessible language, should be an easy read for anyone interested. Got the book as a gift from a niece named Meenakshi we hosted for couple of weeks last year. She gave it to me as a thank you gift, based on a suggestion by her brother Bala. Mentioning them by name since it is heartening to see younger generation taking interest in such topics, as also borne out by the kid at the end of the Jimmy Kimmel video link above. There is hope! 

Book starts sarcastically (but sadly reflecting the zeitgeist) with this statement on the first page that sets the tone and clues you in as to what is ahead:

[Insert generic African proverb here. Ideally an allegory about a wise monkey and his interaction with a tree, or the relationship between the donkey and the ant that surprisingly speaks to the grand gestures of valor.
Sign it off: Ancient African Proverb]

Since the author is originally from Nigeria, Part 1 talks about that country and particularly about the City of Lagos, vibrant & chaotic, smelling like fresh fruit and diesel, its hustle culture, maddening traffic, people eating suya (a kind of grilled meat), and how it doesn't look/feel like many other parts of Africa. It points out that if you go on a safari tour of Lagos, it will probably involve finding the shrewdest car mechanic on the planet and large bountiful markets but not the five big game animals. Parts 2 & 3 discuss in good detail, how African countries were created by Europeans drawing lines on the map, often sitting in Europe, that ended up carving nations that didn't make much practical sense from language, people, culture points of view, that later also helped sow a lot of hatred leading to decades of wars & conflicts. It also gets into the how Africa is always portrayed as a bunch of poverty-stricken people with sick children that are accompanied by flies buzzing around, that had to be saved by white savior imagery. There is an apt Chimamanda Ngozi Adichie (famous writer) quote saying, "If all I knew about Africa were from popular images, I too would think that Africa was a place of beautiful landscapes, beautiful animals and incomprehensible people, fighting senseless wars, dying of poverty and AIDS, unable to speak for themselves." 

While the continent has 54 countries, 2000 dialects, 3000 ethnic groups and more than a billion people, next part does delve into the reasons Africa is often seen as hopeless. Author touches upon seven different dictatorships some of which have lasted multiple decades even though the big man on top is not even being seen anywhere, as they are too old and medically unfit. These countries do struggle with corruption, violence, tribal warfare, including famines that paints them in miserable light. Dictatorship stories get into enough detail about European and American support and interest that had often led to these deplorable situations. Part five that delves into Hollywood's portrayal of Africa that has contributed to so much of negative perception (even when it is supposedly well intentioned) and often being the reason that the continent is perceived as one single country (since movies portray some generic version of Africa without distinguishing countries and cultures) is very valid, but felt a bit stretched to make the point. Sections on African stolen artifacts that fill the museums in several cities of Europe and the US and how these countries & museums dance around in floral language to avoid giving back the stolen goods is vivid and valid. Consider watching this LWT segment by John Oliver dissecting this topic. 

One of my Intel team members named Oluseyi Adejuwon, is originally from Nigeria. When I was invited to attend one of their family functions few years ago (see attached pix), ate Jollof Rice for the first time and learned about its cultural significance. So, thoroughly enjoyed the way one of the last parts dealing with Jollof Rice is written. Nice prose while being funny. Book ends with the question "what is next?" and answers that question, as you'd expect, with "African people need to decide". I always felt I don't know as much about Africa as I do about Asia, Europe or NA. Since I remain curious, I do plan to travel to Africa in the forthcoming years. Would also love to visit universities there, give lectures, talk to faculty & students. So far, my attempts to reach out to universities there to develop connections to offer free voluntary tech lectures haven't yielded any meaningful results. If you have contacts, LMK. If not, consider giving this book a read or at least catch a movie or two made in Nollywood (as the Nigerian movie industry is called), South Africa or even Egypt. Saying that since they are all low budget movies, set in contemporary times, and not big budget productions that tries to transport you to another period or place. Thus, they tend to give little insights into how those societies currently function. I have seen many shows and movies, on Netflix, during plane rides and so on, and found them interesting.
