draft: notes on vermincomposting

Tips and tricks for vc

stay away from acidic items, oily items, meats/cheese (longer to compost)

NO

orange rinds, citrus fruits (attracts fruit flys)

onions, broccoli (strong odors)

salty or acidic foods

avoid grease, fat, bones, fish, and meat scraps. Fats are slow to break down and greatly increase

the length of time required before compost can be used.

Avoid diseased veggies, diseased anything.. compost will heat up, but microbes will still be there after years.

Weed is a problem. If it hasn’t developed seeds, it can be thrown into the bin, but weed seeds can live through the compost cycle and show up in the garden months later.

Tightly closed bins are bad because air won’t go through.

vegetable seedlings are susceptible to microbes in worm compost, and it’s difficult to sterile it. Worm compost is not recommended for seedlings? (verify this)

does one need compost starter? How do you do quality control? What metrics am I looking for? Microbes in air could be enough to begin with assuming air circulation exists in a bin.

Eggshell exception. Wash and dry them out. Do not feed the worms eggs, but they do need calcium. So dry out the egg shells and crush them. Caveat.. save your egg shells.

don’t drawn your worms. Include holes in bin, but can’t leave them outside since las vegas heat is about 115F in the summer time, which is about 35 degrees too hot. Around February the ground surface will get about 45F in the morning.

YES

raw veggies

newspaper strips

to increase population: sweet fruit scraps like banana peels, cantaloupe rinds and apple cores, and pumpkins! (jack o lantern)
old vegetable material, coffee grounds, tea bags, old newspaper, shredded documents, and fall leaves

leaves

bin will need: moisture, air, food, darkness, warm (not hot) temps.

Bedding from newspaper strips/leaves retain moisture + contains air space (does ink harm the soil?)

they also eat bread and wheats

mix scraps with the veggies

sprinkle bedding with water until damp

Composting occurs best at a moisture

content of 50-60% (by weight) there is a ‘squeeze’ test

grass clippings (who has grass anymore?) have nitrogen.. do not throw it away they will decompose fast. But don’t allow them to clump. If they’re big, grind them down. they’re very moist though, and should be mixed with a dry substance to avoid become anaerobic

TYPES OF WORMS

red worms or red wigglers

Eisenia foetida

Lumbricus rubellus

Nightcrawlers are large, and need room. They won’t like bins. Some are naturally deep dwellers. Deep as in 6 feet. Red wigglers are okay with 6 inches.

they’re surface-dwellers. Prefer to live in the top 6 inches of soil

thus shallow bins rather than deep is preferred

for wood bin, line button with plastic? Cover with loose fitting lid. To allow air into bin

after several months worms need to be separated form their castings which at high [concentrations] create an unhealthy environment for them

to prep for harvest. Do not add new food to the bin for 2 weeks.

Make compost tea: just add water, let it step/stew w/e for a day. Then add “tea” to your plants

Name Common Common name Lb/day Temp low Size Life span
Lumbricus rubellus Angle/leave/garden/drift/red march worm 38-40F 4in Cold weather..
Eisenia fetida Red wigglers 2lb eats 1lb/day 1.5-2.5in, 1lb to 2ft-sq 2-5 cocoons/wk 1, hatch in 1.5mo, lives 2-5yrs
Eisenia hortensis European night crawler, belgain night crawler Larger than ^ Cooler temps, moist environments. 1.5yr to settle into composting
Esenia andrei Tiger worm Unpleasant order?

Temps above 85F are harmful to worms. They will try to leave areas that hit 95F. If they can’t escape, they will die. Proteins will denature, etc. (can worms get heat strokes?) Above 80F will slow down the decomposing activities. Worm cocoons can survive freezing temperatures for a couple of months even if their parents die (how sad.. :’(

Logging the Read Books

Alternative title: Blogging the Red Books

While reading this, I though, “Why not?” Here’s a list of in-progress books and other books/writings I’ve come across in the past that I simply should share with the whole world wide web. Not being a fan of 3rd party tools that harvest and conveniently classify your information, here is a good enough place to put it for anyone who cares enough to know what is on my mind.

In progress:

The Psychology of Reading
Insup Taylor and M. Martin Taylor
ISBN: 0-12-684080-6

I got lucky and found a hard-copy of this book for 3 dollars 2 years ago. It’s been sitting in my shelf that whole time and afterwards I’ve been using it as a stand because the hard cover binding was the perfect width for one of my projects. I purchased it just to read a few sections that caught my attention when I first looked through it, but when I actually started reading it from the start it seemed to me to be something very fundamental. I read somewhere (probably this book) that language shapes the way you think, and this book goes over not only roman based languages but also the ones form the Eastern world. I warn people never to trust a biology book that was published more than 10 years ago, and physiology is applied biology. So, I don’t know. This version was published in 1983, way before I was born. I’m sure there’s going to be some outdated information (or even entire theories), so I should keep reading it with the idea that some of the stuff in it might not be true anymore.

Reading wish-list:

n/a

Read:

The Information: A History, a Theory, a Flood
James Gleick
ISBN-13: 978-0375423727

It’s a simple enough read, but it’s structured on themes more than it is chronologically. For example, he keeps referencing back to Shannon in almost every other chapter, but I guess a person can’t write a book about information without mentioning his work. Geick’s limits himself to the decimal definition of a kilobyte and ignores the binary definition of 1024 bytes. This leads me to believe he would also be the type to pronounce gif as jif. But really, it shows how in depth he gets into the technical subjects. The section on qubits was elementary at best, and I assume he included it in the book mainly to claim full coverage. Upon finishing, I couldn’t really figure out what the thesis was to this book. Was it about information overflow? The epilogue sorta left me hanging. I learned plenty on the history side but not so much on the theory side. The flood portion seems rushed at the end. Unless I missed something, Geick seems to have really just dedicated one chapter to it. History was the stronger side of this book.

X is just another way for Y to make more of X

I don’t mean to be bias with the stuff I post here, but I found that the best books I’ve gone through were the one’s written by folks with Ph.Ds. Maybe it’s because they’re experts on the topics they write on, or because they’ve had 100’s of hours just doing what “writing” is. Therefore, they portray their ideas better than the layman. I don’t even want to give mention to the worst books I’ve come across mostly due to embarrassment of proclaiming I’ve picked them up once upon a time, but you don’t always know that until after you’re more than half-way through the book. We shouldn’t propagate bad ideas, but at the same time we shouldn’t block ourselves from ideas/thoughts we disagree with. It’s a struggle.

To be updated..

Back to the Basics: Crayon, wp-LaTex, and vimWiki

Before I forget, I should review some of the basics.

So, this is a blog, and having your own blog requires some maintenance. It’s like owning a house except the servers are hosted in Arizona, the domain name is registered in France, and I guess you’re not owning said house. You’re renting hardware space in someone else’s basement.. Note where your local and remote machines are. Okay, so I need to remember how to bash function. How to bash function? No, how about just a bash alias?

while we’re at it

but the alias needs to be remembered after reboots

include in file, continue with life.

So with this, instead of memorizing a very long username + host domain I can access my blog with only a few magic words.

.. checkmate. I guess we could include the password as an argument but, no. So long as remote and host have authenticated each other before, this ought to be enough.

Now, without needing to activate FTP we can update and modify everything in the blog via command line. Will need WP-CLI. Fortunately the freebsd log files kept track of the commands I issued to it oh so many seasons ago, so simply pressing the up arrow key and holding it for a minute or two sent me to the keystrokes. the magic keywords are simply:

remove/deactivated unneeded plugins which could become hazardous to your health. For more information these functions have been well documented at http://wp-cli.org/docs/ or simply refer to the man pages

How to syntax on wp?

since we’re going to be typing code here and there, a nice plug-in to have is:
https://wordpress.org/plugins/crayon-syntax-highlighter/

from here we can simply dl to our own machine or even use SSH from the remote machine to dl the file from a selected URL https://downloads.wordpress.org/plugin/crayon-syntax-highlighter.zip and then save it to the remote machine’s plugin directory, then..

via wp-cli
search for “crayon” to get a list of plugins already available through official channels

So now we have pretty colors that support languages beyond what the regular vanilla wordpress supports. you could also git clone or wget + unzip from https://github.com/aramk/crayon-syntax-highlighter.git to get the same affect, but we’re already using wp-cli to run an update so might as do it from the remote host.

Next order of business: LaTeX.. how to LaTeX?

simply typing in:

should produce:

i\hbar\frac{\partial}{\partial t}\left|\Psi(t)\right>=H\left|\Psi(t)\right>

Unfortunately, I won’t get to see it until I preview it on the wordpress had it even worked to begin with. Apparently a viable plugin would need access to a latex server in order to generate some sort of image. It could be a .png and there’s even one that generates .svg vector images, but it pings to some guy’s web basement server and I’d rather not have my blog reliant on whether or not some random guy forgot to pay their electric bill. Of course, there’s always the option to self host a latex server on my own or a remote machine. A search for latex on the plugin menu yields several attempts at doing this.

While searching, I discovered an old .png generator for latex inputs. It seems to be not-so-old and the current method from which wordpress.com uses to render .png images. You can play around with the below URL.

So, there’s a wordpress.org plug-in that utilizes a  similar, if not the exact same generator from wordpress.com. Note the distinction between the .com and .org service. It also has an option to generate from a self hosted server. Humm..

pro: less bandwidth
con: if access to wordpress.com goes down, image rendering capabilities go down with it. This will happen several times a year depending on who’s attacking the DNS.. but if the DNS is down this website will probably be inaccessible as well. Except in Australia. There’s a story to that.

To be reliant on external services.. Sure, to an extent.

how to vimwiki?

I’ve been reliant on gnote and random .txt files scattered around my drive to write down random things. A friend of mine recommended vimwiki, almost randomly like he had been reading my mind (or had shell access to my laptop).

The vimwiki is more of a plugin than anything, and should be easily installable through pathogen.

You can find the installation instructions here: https://github.com/tpope/vim-pathogen
and for vimwiki: https://vimwiki.github.io/

I shouldn’t need to go through writing the instructions here because the details are literally right there.

What I did need to figure out was that I was expected to make my own index.wiki file inside the ~/vimwiki/ folder. I was surprised when I could “enter” and “backspace” between files joined together by a link. #jawdrop.

creates a folder with a html transaction (along with a .css) of the page you’re on. It doesn’t follow through the nested links though. With maybe about a 100 functions on that help page, it’ll take a while to get acquainted with this program. I think it’s safe to say it has more functionality than what I had been previously using. I’ll play around with this for a few weeks and then decide if I’m better off with it.

What’s next? humm… I have less than 4 days to prep up on my Korean, toy around with some java, and I think they’ll be putting me in something about a “smarter cities” think group. I suspected it was related to the CES hackathon but that’s this weekend. I should probably go to that, but I need some ‘me’ time and me time includes prepping up on my Korean and toying around with some java. Also, my friend tells me I need to get more sunlight. I do.

[edit] Had been invited by some friends to join them at the CES hackathon this weekend, and despite making an attempt to print out my ticket, I just received an e-mail specifying that entrants needed to be registered for the CES portion by 7 days ago. This would be a separate registration process, and they’re only letting the first 450 people in. It’s fine. More ‘me’ time. Also,


will attempt to change all your black pixels into blue ones in case your printer ran out of black ink. Sadly, I also just found out that we have a Kodak that refuses to print if it detects the black is low (or refuses to print black if it detects the color is low). Hardware should not be used like this against the consumer’s interest. Alternatively I could’ve gone to a UPS store or library that opens early to get something printed – mobile ticket barcodes ftw.

On a lighter note, I finally received the schedule for the Ajou workshop on Monday, so it looks like I’m slowly placing things on that to do list.

Test Post Please Ignore

To be honest, it would’ve been simpler had everyone used the same nomenclature, but I got to play around with all these different configurations.. It’s not like my time is worth anything – maybe it’s a French thing? Like, imagine if it’s just something you could put blame on a cultural thing. Their culture is different from ours, and our culture is somewhere hosted in Arizona – I’ve no clue what type of culture Arizonians have. Either way, despite being across an entire ocean; I’ve managed to assemble data from several sources to get this thing running. CNAME, zone file, unregistered proxy domain, mail exchange, etc. Now all we have to do is wait for DNS propagation. Time Till List – approximately 3 hours. Pretty standard.

Learning is slow, but it leads to something. It always has. I can’t put blame on culture, not as much as putting blame on me for not understanding it. There’s usually a missing context somewhere. My WORST experience overall was probably trying to figure out dynamixel specs from their source. Of course, it’s all there if you could speak/write Korean, but when an employee made the documentation your academic life depends on.. it’s frustrating. I mean, it certainly doesn’t help, yet it’s the only help you have. I’m sure the guy on the other side is 50 times smarter than I, but I just can’t understand him (or her). It’s a similar experience, except this time the ocean you have to cross is the other one (as opposed to the French one). #rant

Yet again, I feel validated in having gone with vim and acknowledging its superiority over emac. I spent the last several hours in someone else’s server (rented) making configs here and there, and just overall exploring. Rented doesn’t come with sudo access unfortunately, but a lot (most) of what I can do in a /home directory,  I can do over there. Time and over again, I’ve found myself in need of vim; and it’s proven to have been the better choice. Do you know how many times I’ve needed to use emac for anything? None.. zip.. 0 – as in “zero” times. I’ve needed to know vim for a broad range of applications.

Imagine being inside a multi-hundred-thousand dollar system just digging through code, all the way to fixing a twenty-something dollar raspberry pi. Vim is so light, and you can pretty much expect it to be installed in any system you plan on using, especially of it’s old. If by chance it’s not on there, getting it on there isn’t difficult. My chrome net book was the first time I really needed to use vim. This was maybe 2 or 3 years ago. My ubuntu installation crashed, and so I needed to find another way to get the laptop running again because let’s face it a chromebook isn’t’ really a laptop. It could be, but the operating system leaves so much more to offer, and I don’t particularly like the idea of being locked in anyone’s ecosystem for too long. But my efforts failed, and I found myself in the middle of a bad install with an unsigned BIOS I had chosen to replaced the standard chromebook one. The only way to do that was to short the leads underneath the the laptop so the write protection would turn off – a simple jumper. I felt proud, it being a small, but meaningful hardware hack; but I soon found myself staring at a terminal that wasn’t acting right.

At its bare minimum, my new bootloader had some software to help it get to through the rest of its installation. I was going to put ubuntu on it, because at the time that was pretty much the only linux distro I had any experience with. Among that short list of software in the boot-loader was vi. Not vim, just vi, and I knew what it was. In the past I had forfeited getting acquainted with it because who in their right mind would use such a primitive text editor when you have all these other O-M-G-EYE-CANDY alternatives with so many other useful features? Why would any sane person torture themselves with this nonsense keyboard layout? But there I was, staring at a terminal and I had no other choice but to figure it out. So vi it was.

Fast forward a year or two, and vim’s my favorite editor. It wasn’t until, about 8 months ago that I REALLY began to appreciate it, and even more so this past summer.  Back in January, I was sitting next to a professor watching the guy do kongfu coding on that aforementioned multi-hundred-thousand dollar system. I remember asking him why, and it didn’t make too much sense back then, mostly because I wasn’t the one doing it. Regardless of what you’re working on, it really comes down to the fact that you’re probably working on a terminal. Furthermore, that terminal, probably isn’t on your computer. It’s somewhere else, on an entirely different platform or maybe on an entirely different planet (or not a planet, maybe it’s traveling beyond the now detittled Pluto, and the only way to interface with it is to recompile a Fortran oracle by which the only means to edit is through..). On top of that, you’re probably connected to four different platforms at the same time. Some of these computers might be running sub-controllers, and somehow you’re beyond seven layers away. The good news is, you can control all of them; and instantly reprogram and reedit them while they’re running, (even literally as they’re running/or flying), through vim.

PuTTY was my first real linux experience, granted that was through a windows XP and 3 laptops ago. As a freshman in mechE, we had an amazing professor who made us use it, but this wasn’t something that was drilled into typical mechE students. There’s a real lack of computer programming experience brought into us by the intuition we pay tuition to. There was hardly any back in high school and I wonder how the education system has changed since. So, any of this, is something students will have to learn on their own (or they could quad-major in everything). The other day was my first time being inside of a BSD system – a unix system. I’m a senior, so maybe there’s something poetic to be said about this? So yeah, vim. Not because of the plug-ins or its advanced features, but because there’s beauty in simplicity. It somehow became simple. Also because of the terminal thing. That and I love my color syntax. It’s awesome.Oh, and I’m also on awesomewm. Seven years ago, I wouldn’t have dreamed of being able to write code like this. Seven months ago, I could hardly believe I was controlling platforms like this. It always felt surreal, like I didn’t belong here; and it still does at times. Seven layers ago, I was somebody completely different.

Let’s recheck that propagation
