Welcome to Jovan's Research World!


Well it's been 5 months since I logged onto here to chronicle my adventures. I'm learning about glow discharge optical emission spectroscopy for work. And at Bookmans I found a Dover Publications copy of A.E.H Love's Treatise on the Mathematical Theory of Elasticity. It's a pretty gnarly book in vector analysis and calculus. I'm looking forward to reading it as well as all the documentation for GD-OES.


Thinking about transcribing my handwritten journals to the digital world. I can't decide what word processor I should use though. Should I do it with my Alphasmart Dana first? Or maybe Microsoft OneNote, Microsoft Word, Google Docs, or WordGrinder on the SDF server? I can't decide! Definitely will be stored on the cloud for backup. I like typing in my Alphasmart. Maybe I should start then and then transfer to OneNote, since I use OneNOte every day and like how easy it is to cross-reference, index, and search through the documents I create there. Yeah. OneNote it is then.


Just saying hello. Glad this server is still in service. RIP PolarHome! I miss you!


Going to stay up late reading chapter 2 of Dieter K. Schroeder's Semiconductor Material and Device Characterization for work. Need to do some consulting tomorrow.


Have fun! And keep learning!

That's what I'm doing today. I'm having fun and learning as I solve some electrical test mysteries at work. There is a strange occurence at work where a user noticed in his diode tests that if the meter was ungrounded, his forward bias currents were higher than if his meter was properly grounded. How is that possible? I don't know yet. And my boss can't figure that one out yet either. We will need to investigate with a resistor later today and attend a conference call tomorrow with the customer.

Posting some music I've recorded yesterday during the lunch hour just for fun. They all need a lot of polishing, but the bones are there. All original work by me.


I'm happy to see that Ctrl-C was not killed off by CoronaVirus.


Sometimes I try to keep up with my old goals. Like to update my journals in every server I have access to. Yesterday I was supposed to do something with my Grex.oRg account. Not much I can do there since it doesn't have a website for me. So I just write some gibberish in Markdown in a personal folder I have. Today it's you ctrl-c! So I have this fun little weblog to update. Apparently it's been longer than I imagined my last update was. Originally I intended to update this thing weekly. Oh well. I wonder if Wordgrinder is installed here. My hand is starting to cramp up for some reason.


Well it's been a long time since I logged into this server. I used to follow a routine, a rotation for server activity, at least to post a little blog entry now and then and check out for anything new and interesting here. A lot of tilde servers have disconnected over the years. I'm glad to see that ctrl-c still kicks.

Lately I've been spending my lunch hours either with the family, or working on special projects. That's why I have not posted much. I tried to do Inktober in October, but only got a few days worth of images finished before other things took up my time. Then November came and I wanted to do NaNoWriMo, and I got 45 pages in before I ran out of lunch hour time for it as well. I still want to finish both projects, when I get a free moment I try to work on them.

I sold my SGI O2 this week. I hope it arrives in one piece. I'm going to sell another one so I can buy a Pilot Custom 823 fountain pen. It's just too hard finding space, time, and money to run those machines the way I originally envisioned them. It's easier to work on software projects and develop on the cloud, or with a fistful of Raspberry Pi boards. I have one little Pi Zero W running 24/7 now at home, and that's enought to quell my computing bug. The SGI O2 with Irix 6 is am amazing machine for it's time though. The hardware is limited, but they squeezed every ounce of performance out of it with their mad software skills. It was fun studying it, but now I must move on.


Goodbye ~.works! You will be sorely missed! I don't even know what I blogged about in your server, but I'm sure it was just as random and useless as what I write about in this page.


I just bought a bunch of books about functional programming through Humble Bundle. One of these langauges is Rust, which my main server MetaArpa does not have installed, and I don't want to install anything more on my laptop and work PC. So I'm happy to learn that Ctrl-C has Rust installed already! I now know what this blog is going to focus on now for the time being! I also have books and Scala, Erlang, Elixir, Clojure, Haskell, and Javascript. The only language I have installed locally is Clojure right now, and maybe Haskell on an old laptop at home. Maybe I should try installing all of these languages in the really old laptop I currently do nothing with at home. That would really test how efficient and functional these languages are on a single core machine running Windows 10. Takes away from the concurrency features that these languages are supposed to have though. We'll see.

Most of these languages can be found on the MetaArpa server that SDF provides, but Rust is only on Ctrl-C as far as I know. And tilde.team has Elixir isntalled. So that just leaves, Clojure on a server, even though I have it installed at home and at work already.

More to come when I get a free moment to read the books.


Happy New Year CtrlR! I've been good. It's good to see you are still running after over a year! I'm sorry I have not been very active with you, I have so many other servers I have been ignoring since the baby was born. And I spend a lot of time in the Analog world with my pencil and notebook just rambling away. Maybe I'll soon post some stuff from those dead tree notebooks into this blog. I bought an AlphaSmart Dana Wireless which I hope will help me with the transition from analog to digital media. Other than that it's just been happy times working and taking care of the family.


Nice to still you still running ctrlc!

As for myself I've been using Instagram a lot and am participating in #inktober. Check it out


Captain's Log

Working on a new project these days. It's been a long time since I updated this blog, but then again I have like 20 blogs and it takes times for the rotation to come full circle. I actually have four projects I'm very interested in right now. I want to simulate the human body, so I have been learning more about the WholeCell and ECell projects. I also want to learn more about machine learning, so I'm participating in Kaggle competitions again. I love modeling and simulation, so I'm trying to compete in a NASA sponsored fluid dynamics code optimization contest. And finally I have some perverse infatuation with True BASIC, and would like a create an improved interpreter for it using Perl and Marpa::R2.


Captain's Log

This week has been a great week since I don't have any online courses to worry about. I will next week though. I need to meet with my advisor and figure out how I'm going to finish my degree.

I love notebooks.

I've been reading a lot of books lately. I'm trying to get into the molecular theory of gases and liquids. And I'm reading something like 5 science fiction books right now. Let me see if I can list them all here.

  1. Version Control by Dexter Palmer
  2. Sleeping Giants by Sylvain Neuvel
  3. Asimov's Science Fiction Magazine July 2016
  4. Dream Paris by Tony Ballantyne
  5. The Windup Girl by Paolo Bacigalupi

And I'm just prioritizing what I read based on my location throughout the day and which ones were checked out by the library. So Version Control gets highest priority because it took me forecver to check it out of the library. But if I don't have access to a computer or tired of reading from my phone then I read Asimov's or The Windup Girl because I have physical copies of those books.


Systems update

After the bountiful supply of tilde shells that flourished after Paul Ford's original experiment, this is one of the few that have survived. It's been a long time since I've had a chance to write in it.

Since my last post (I never did finish my NaNoWriMo project), I have been working on school, work, family (not in that particular order), and have been reading a lot of books with every spare toilet break I get. I've been learning more about the Perl programming language, and am very happy to be using it exclusively for my homework assignments this summer.

At work I'm still using LabView primarily but I'm trying to squeeze in as much Perl as possible to help me get things done more efficiently. I have at least 5 projects on my mind as I write this, all for Perl.

At home I'm still trying to figure out what's the best programming language for the family.

I've been reading and using Markdown a lot lately. It's too bad I didn't start this blog in Markdown syntax, that would have made things a bit easier for me. I am also falling in love with WordStar keybindings, and have been exploring all the various editors that can support it.


I'm participating in NaNoWriMo

I'm trying to finish my first draft of a novel I've had in the back on my mind for a number of years now. So far I'm a little past 10,000 words. I'm behind, and I'm cheating a little by filling in pages with old journal entries from my past in the hope that I can twist events around for the character to live through. Sorry I have not updated this blog in a long time. It's hard juggling work, school, family, and WriMo all at once.


Trying to win a free notebook.

Today's research

I spent the first two hours of the day working on setting up electrical repair on Cherry prober today. There is alot of work in aligning the needles in both the x-y plane and fitting a planar function in the z axis. The best approach is to align with the probe card as the center reference and adjust using my "realign" function. The z axis is adjusted using the coordinates of the four corners. The numbers need to be copied into the test file and into the Mother Intel Test Sequencer_v1p1.vi. There are boundary checker problems but they can be circumvented by starting in the proper initial condition.


Repairing my Tandy Model 100

I have a Tandy Model 100 that I believe never worked. Today I started to look into why it does not work. The power seems ok, but nothing appears on the LCD screen. The contrast dial appears to work but I just see a blank screen. The clock on the 80C85 is showing an 80 us cycle time. I don't know if that's good or not yet. The 4 MHz crystal does not give me any output, but I think that's becuase I don't know how to test a crystal oscillator with my oscilloscope yet.


Computational Chemistry using the Tandy Model 102

Today at work I'm back to repairing panels. So while I wait for operations to complete I can write in my blog about how I'm waiting for operations to complete.

What I've been working on lately with my free moments is going over the book, "Computational Chemistry Using the PC", by Donald W. Rogers. I've been translating the QBasic and True Basic code examples in the chapters to Tandy Model 102 Basic to help me understand the concepts. I've been backing up the code on github. It can be found here: https://github.com/navoj/TandyModel100Basic.git

Right now I'm trying to solve a heat capacity equation using the Commodore 64 Basic emulator on my phone. It uses a slightly modified version of the Model 102 code I wrote. The equation is:

eqn:= (a+c*x+e*x^2)^2 / (1+b*x+d*x^2+f*x^3)^2

Right now I'm trying to compute integrals more efficiently using the Model 102. I've learned how to compile assembly language programs within the Model 102 using a Basic program called CMZASM.BA, which I obtained from the Club-100 website.


Welcome to my web page. Here I will chronicle my adventures in computer science and engineering. Right now I'm working on a distributed search engine to try to find counter-examples to Beal's Conjecture. I don't actually think I'll find anything but I'm doing it as an exercise in distributed computing with shell accounts scattered across the internet being shared with other people. I hope people won't mind me sipping a few cycles here and there while they compile their programs and write their web pages.
