Thoughts on the Status of My CD Collection

(This is a repsonse to Streamlining Physical Media: What's the Status of Your CD and DVD Collection? over on my friend Chris' blog. Go there and read that first, then come back and read this...)

I'm still a CD person. I just got my first car with a CD player in it a few years ago. And I still buy them, although mostly from library sales and thrift shops. It's kind of dumb, I know, since CD's have none of the good aspects of either vinyl or mp3s. But I remember when having my own CD player and buying CDs my parents didn't want me to listen to was a big deal. And I feel that sort-of-prideful collector's urge when I browse my collection "Look at how awesome my collection is. You can tell I'm cool."

That said, I've recently been facing up to the fact that CDs are going away. I have started to find old CD's that won't play in old CD players. CD technology itself has a pretty short lifespan. So the past few weeks I've started ripping all my CD's to a computer with a big hard drive. It's like 2001 all over again. I'm setting it up so that I can stream my own collection to myself over the Internet. Kind of like my own private Pandora or Spotify.

I've even found some old mix CD's and playlists for potential future mix CD's written down on scraps of paper in my old college stuff. I'm planning to re-create them in electronic playlist form on my music computer. A mixtape is a powerful thing.

As for DVD's, I went through a pretty short period of buying a lot of them and then quickly quit. I probably never owned even forty. Eventually, I'll do the same thing with them that I did with the CD's: rip them to a computer, and stream them to myself around the house or over the Internet.

I've never bought music digitally. Ironically I feel like digital objects are too ephemeral. That and DRM is evil, etc, etc. And I never felt the same satisfied ownership with online services like Pandora and Grooveshark that I still feel when I buy even used CDs.

It's a funny coincidence that you posted this just now. What prompted me to go through all my old CD's has been getting a lot of my old stuff from my parents' house. I've been sorting through all the stuff that, at some point, I thought I would want to keep forever. It's hard to get rid of anything that feels like it was a part of what made you who you are. A lot of the things I'm finding in my old junk remind me of times that I had totally forgotten about. When I then make the decision to get rid of it, it feels like I'm choosing to maybe never remember that part of my life again. It feels like I might be getting rid of a part of myself.

I guess for a while, at first, becoming an adult means adding things (to your CD collection and to your personality) - that is to say growing and expanding. And then at some point it becomes also about shedding things from the past.

Fun with Processing

Building on the brilliant work done by guru, I made my first baby steps into Processing this week.

Guru's code generates a grayscale image and then creates a height map from that image. Then it allows the height field to be exported to STL. This of course means that we can attempt to print it out on our MakerBot or RepRap.

For me the obivious next step was to modify the code slightly to allow any grayscale image (or any image at all) as input to the program, building a 3D object from a 2D graphic.

Here's what I came up with:

/**
generate a stl file from a heightfield

by Guru

modified by Dave Menninger
*/

import processing.opengl.*;
import unlekker.data.*;

PImage img;
STL stl;

void setup() {


  size(640,480,OPENGL );
  smooth();

  img = loadImage("kashmir2_elev.jpg");

}

float a = 0;
boolean imgmode = true;
boolean rot = true;

void draw() {
  background(0);
  if ( imgmode ) {
    image(img, 0,0, width, height );
  } else {
  lights();
  fill(128);
  stroke(128);
  noStroke();
  a += 0.01;
  pushMatrix();
  if (rot) translate( width/2, height/2 );
  if (rot) rotateX( PI/2 );
  if (rot) rotateZ(a);
  img.loadPixels();

  float h = 100;
  float l = 10;

  translate( 0, 0, -h + l );


  if ( !rot ) stl=(STL)beginRaw("unlekker.data.STL","guru.stl");
  
  for( int x = 0; x < img.width; x++) {
     beginShape(TRIANGLE_STRIP);     
     for( int y = 0; y < img.height; y++) {  
       float h1 = map(brightness(img.pixels[ x+y*img.width]), 0,255, 0, l);
       float h2 = h1;
       if ( x < img.width - 1 && y > 0 ) {
           h2 = map(brightness(img.pixels[ x+1+y*img.width]), 0,255, 0, l);      
       }
       if ( x == img.width - 1 ){
         h2 = 0;
       }
       if ( y == img.height - 1 ){
        h2 = h1 = 0;
       }
       if ( x == 0 ){
         h1 = 0;
       }
       if ( y == 0 ){
         h2 = h1 = 0;
       }
         
       float x1 = map( x, 0, img.width, -100, 100 );
       float y1 = map( y, 0, img.height, -100, 100 );
       float z1 = h1 + 10;
       vertex( x1, y1, z1 );
       
       float x2 = map( x+1, 0, img.width, -100, 100 );
       float y2 = map( y, 0, img.height, -100, 100 );
       float z2 = h2 + 10;
       vertex( x2, y2, z2 );
     }
    endShape(); 
  }
  
  
  beginShape(QUAD_STRIP);
  vertex(-100, -100, 0);
  vertex(-100, -100, 10);
  vertex(100, -100, 0);
  vertex(100,-100, 10);
  vertex(100, 100, 0);
  vertex(100, 100, 10);
  vertex(-100, 100, 0);
  vertex(-100, 100, 10);
  vertex(-100, -100, 0);
  vertex(-100, -100, 10);  
  endShape();

  beginShape(TRIANGLE_STRIP);
  vertex(-100, -100, 0);
  vertex(100, -100, 0);
  vertex(-100, 100,0);  
  vertex(100, 100, 0);

  endShape();
  
 
  if (!rot)
    endRaw();
  popMatrix(); 

  }
}

void keyPressed() {
  if (key == 'e') {
    noLoop();
    redraw();
    rot = false;
    a = 0;
    redraw();

  } else {
   imgmode = !imgmode;
   rot = true;
   loop();
  } 
}

Here are some of the results I'm getting:














I should note that I haven't actually tried to print any of these yet. I'm hoping to tweak it to get slightly better models before I take that step.

RepRap Rainbow Packs - ABS Group Purchase

One of the plastics that Makerbots and other 3D printers use is called ABS. ABS comes in many colors but most people have been using Black and "Natural" up until now because they are the most commonly available. We want to order some ABS plastic in Red, Green, Blue, and Yellow too so that we can make more fun and happy objects. The plastic is kind of expensive and it has to be bought in somewhat large minimum quantities. We want to fund a group purchase of all the colors and then divvy up the colors in portions to our backers so that each person can get a smaller amount of all the colors. We also want to be able to make fun colored objects that we can send to backers.

Here's the plan:

Once we get the money, we will place an order with Village Plastics. We are going to be looking to gather at least $2000 to start off with so we can get a 30 lb. spool of each color.

Once we get the plastic, we will spool out the 1 lb. quantities and mail the Rainbow Packs out.

Help spread the word by linking to the Kickstarter project page so we can help out as many people as possible. Thanks!

Video of my Ignite Cincinnati talk

Video of my talk about Hive13 at Ignite Cincinnati last week:



It was a great event and I definitely plan on attending the next one on 03/03/10.

Hive13: Epic 2009

Just posted a review of the epic year Hive13 had in 2009 on the Hive13 blog.

Plans for 2010

What a year!

I can't believe all the awesome stuff I was able to participate in this year. I think it is due in small part to blogging the list of stuff I wanted to do at the beginning of the year and then checking in on the list periodically.

More important than the list itself was the conscious effort I made to change how I approach projects and activities. The best way I can describe it is I made the decision to say "yes" to things. Instead of being scared and nervous about new projects and responsibilities I decided to Just Do It. I recognized that there was a very clearly defined emotion that would make me chicken out from doing the things I wanted to do and being the type of person I wanted to be. So I decided that whenever I have that feeling, I should do the opposite of what it tells me to do. As a result I've been involved in many exciting projects that I definitely do not regret.

I'm also a believer in putting your goals down in front of you and tracking your progress. I think making things concrete that way makes it easier to actually make progress. That ranges from putting numbers on things and making graphs to just writing out your thoughts a the end of the day. It's easy to lose focus. When some free time comes along and you're not sure how to spend your time it's easy to get distracted and waste your time away doing stuff you don't really care about.

At the beginning of the year last year I made this list of stuff I wanted to try to do. It wasn't so much a list of new year's resolutions, but more of a bunch of things I didn't want to forget about. I checked in again on my list in March and July.

Cooking, Bread, Beer, Cheese, Kombucha - I learned a lot about food ways this year but haven't turned any of it into a regular practice. I am happy with all I've learned and may get back into some of the recipes. I also started packing my lunch on a somewhat regular basis which I'm pretty happy about. I'd like to keep that up.

Local Food, CSA, Farmer's Markets - I did a lot of thinking about this and shopped at a few farmers markets. I need to work a farmers market into my weekly routine. I'm proud of this big table I created about CSA's in the Cincinnati area; I'd like to update that for the new year. I may sign up for weekly service from this company in 2010.

Gardening, Composting - Never did get a garden started, but I did grow some sprouts so that must count for something. I also didn't do as much composting as I wanted to, but I did build an outdoor compost bin so I'd have a place to get rid of collected kitchen waste. I plan on increasing my usage of the compost bin in 2010 and use the compost for a garden. I also want to get a rain barrel. Another idea I had was to make a big window hydroponic garden system at the hackerspace.

Paper Making, Crafting/Upcycling, Knitting/Weaving - I made another big batch of paper for Christmas cards and they turned out pretty alright I think. My next goals are to try and get smoother sheets and to try putting seeds in the mix.



Rapid Prototyping, MakerBot - This is an enormous success for this year. Getting a MakerBot is one of the most awesome things that happened to me this year. It ranks up there as one of the most awesome things I've ever done. Every time I make something new with it I get excited. I've even contributed some objects to Thingiverse and they were featured as a "Thing of the Week" on the Thingiverse blog. My goals for rapid protoyping are to basically build more rapid prototypers. I already have firm plans to build a Mendel and a CNC router. I also started a regional group for reprappers and makerbotters in the SW Ohio area that I should spend some more time on. I think rapid prototyping / distributed manufacturing / fab labs is a big and important phenomenon and I love being a tiny part of it.

Online Projects - All of the projects I was working on around the beginning of the year of somewhat stagnated, but I still believe in some of them. The biggest thing I hope to do in the first months of 2010 is to get skilled at using Drupal and hopefully that will allow me to flesh out some of the ideas I've had for websites. I've got a good Drupal book and an idea for a basic site I plan on building ASAP.

Local Currency - This has been on the back burner, but the local currency conversation has been heating up online and there are a lot more resources online now than there were at the begininng of the year.

Hackerspace - This is probably the biggest thing that has happened with me this year and I still can't believe it sometimes. Literally a month or two after I was thinking about starting a hackerspace, some other folks and I managed to create one. It's called Hive13. It is really cool and deserves a post of its own. My goals for 2010 with the hackerspace are to have more classes and build up our tools / fab lab. I also hope I get a chance to visit some other similar groups in Cincinnati and other hackerspaces in other cities.



Libraries - This seemed like a life-threatening year for libraries but we managed to come out of it ok. I'd like to continue to explore the ideas I was having about the future of online / decentralized libraries. I'd like to experiment by setting up a personal library online and a library for the hackerspace. I'd also like to make a tool library for the hackerspace.

Screen-Printing - I got some screen-printing gear for my birthday, but I am really sad that I didn't get around to printing anything. I have everything I need. I think first up I will screen-print something cool onto an old sweatshirt. I also have an idea of screen printing designs onto the homemade paper to make gift cards.

Android Apps - I stopped about midway through the tutorials and I don't know if everything I did is out of date now or what, but I'd still like to find time to play with this more.

Clothes Audit - In addition to moving forward on all the projects above, I had an idea for a project that I want to do some time when I have some time. I want to basically inventory all my clothes. I feel like I have way too much clothes and I only wear a small fraction of it. I also want to be able to look at all my clothes in terms of how many days I can go between doing laundry. For example, do my numbers of white socks sync up with my numbers of white undershirts? How many towels do I really need? Just to basically analyse it as a system and then cut out the waste.

In terms of doing stuff instead of just thinking about doing stuff I couldn't be much happier with how 2009 went. It was a very good year. I think 2010 will be even better!

MakerBot Awesomeness

Last night, after the Hive13 meeting Craig presented a quick tutorial on the basics of Blender and showed us how to make simple objects. This was incredibly useful because it got a number of us over that initial hump of not knowing anything at all about Blender. Blender can be tricky to understand, but I definitely felt like I was ready to start making useful models after tonight's short lesson.

In the class we made these hexagonal coin / keyring shapes. After class we started trying to print them out. With this result:



After we played around with the MakerBot for a while, everyone left and I decided to learn how to create text in Blender and I added the "Hive 13" to the coin. I only was able to print it one time since it was getting really, really late, and I found some errors in the design, but I think I know how to fix them. Soon I will have an "official" Hive13 coin / keyring to give out. Be the first in your city to get one!

(Did I mention having a MakerBot is awesome?)

Growing Sprouts

Growing sprouts is hands down the easiest way to grow your own food. I had no idea until I saw a recent post on The Cheap Vegetable Gardener (which is an awesome blog, btw). Basically all you need is a mason jar. Growing sprouts is good for someone who is not home a lot and may not have time to tend to other plants. I recently grew a batch of fenugreek sprouts and they were delicious. I found a lot of helpful information on SproutPeople.com too.

The basic procedure goes like this:

1. Soak the seeds 6-12 hours
2. Rinse and Drain the seeds/sprouts every 8-12 hours for a few days
3. Eat




I got a bunch of seeds that were sold especially for sprouting from Clifton Natural Foods. I don't know exactly if there is anything special about "sprouting" seeds versus any other seeds, but I'm pretty sure you can sprout just about anything.

I tossed about a tablespoon of fenugreek seeds in my jar and covered the top with a piece of cheesecloth. For the initial soak I filled the jar about halfway up and added a couple drops of liquid fertilizer, but I don't think the fertilizer is strictly necessary. Then after I left it over night I drained it. After that I just rinsed and drained the seeds every now and then whenever it occurred to me - like before work, after work, and right before going to to bed. After a couple days, bam I had sprouts.



I ate half of them on a sandwich and ate the other half straight up. I kind of tossed them a little bit first to get some of the seed hulls off, but still had a lot of hulls mixed in. I just ate them.

If you like sprouts (which I know is not everyone), I highly recommend giving this a try. It really could not be easier.

MakerBot Construction - Day 1

Here's how far I got:



The body and z-stage are constructed. I posted some more pictures of the construction on Flickr. Next up, I will build the x and y platforms. After that, electronics!

Owning a MakerBot is totally awesome.

MakerBot

This is a MakerBot:



MakerBots are awesome open source 3D printers.

A MakerBot - in kit form - is on its way to me right now via UPS. :) !!!!

Said MakerBot will live at Hive13, the hackerspace in Cincinnati.



The MakerBot is a project I've been super excited about for a long time. It's a big reason why I wanted to start a hackerspace in the first place. I'd love to meet up with anyone else in the area that has a MakerBot or who is interested in them. We have several members in Hive13 who are into CNC machines in general and it would be a good venue to share ideas and help each other out with projects.

Once the MakerBot is built I'll be looking for interesting projects to work on using it. I have a few ideas right now, but I want to get cool ideas from other people too. If you have something you'd like to print, or something you'd like to design using the MakerBot let me know. Meanwhile, get some ideas from Thingiverse and watch this video:

Personal Stats

The recent popular trend in keeping stats on yourself seems to be peaking with a recent issue of Wired magazine focused on the topic.

Whether it be the Hawthorne effect or the Prius effect, I believe that using feedback in the form of personal stats can have a positive effect on your ability to control and understand your own behavior.

To me Buster Benson appears to be right on the leading edge of this whole field, with stats (and lovely charts) tracking many, many aspects of his life. I'm using his google spreadsheet to track my Infinite Summer. Matt Haughey also wrote a blog post that brought this into focus for me recently.

I've experimented with this stuff in various ways myself. In college I made a big chart on poster-board to track my sleep. More recently I tried using daytum to track my caffeine intake.

All these things are inspiring me to begin working again on an idea that i first had way back in '06.



I'm a big fan of Lifehacker - in particular the work of Gina Trapani and Adam Pash. Gina has written a nifty set of tools for todo tracking. One of those tools is an AIMbot that can interact with her todo.txt files. Adam later modified this bot to be a personal budget tracker.

I actually ran the budgetbot tool for a short time, but ultimately didn't use it enough. Later I modified it to be a gas mileage tracking bot. I sent it SMS messages everytime I filled up my tank, and a page on my website showed a nifty little graph of my MPG over time. Eventually I moved hosts or something and the code was lost.

Ever since that time I've had more and more ideas for ways to modify the bot to track various stats. I've never sat down and actually done it though. I'm putting this idea out there so that maybe I'll either do it finally, or inspire someone else to do it.

I'm imagining a general-purpose bot/service that can track all these different stats. I could of course just write one big uber-bot by continually hacking the existing bot, but the software engineer in me wants to break it up into a core with many plugins. And instead of simply using sms/AIM, it would have a trendy REST/XML/JSON API or something. Or maybe that would all be overkill.



Here are the ideas for "plugins" that I can see being useful and probably easy to implement:

TodoBot: The original. This is obivously the most mature, since it's already been done for several years.

BudgetBot: Also well defined due to being already done.

GasBot:

commands:
gas gallons miles [price] - adds an entry to the db
mpg - returns your most recent miles per gallon or maybe your current average mpg
bestmpg [n] - returns the all time best mpg you got in the last [n] months, default n=12
worstmpg [n] - returns the all time worst mpg you got in the last [n] days, default n=12

WeightBot:

commands:

weight pounds - adds an entry to the db
weightavg [n] - returns your average weight over the last [n] days, default n=30
hiwieght [n] - returns your highest weight in the last [n] days, default n=alltime
loweight [n] - returns your lowest weight in the last [n] days, default n=alltime
trend - returns whether your weight trendline is pointing downward or upward

BowlingBot:

commands:
game score - adds a game's score to the db
gameavg [n] - returns your average score over the last [n] games
hiscore [n] - returns your best score in the last [n] days, default n=alltime
loscore [n] - returns your worst score in the last [n] days, default n=alltime
handicap - returns your calculated handicap

I think there is a general structure emerging (addnew, best, worst, average), but each one is slightly different.

I'm envisioning a basic storage structure (the existing bots use .txt files, but a real DB may be in order) that can be accessed in various ways. Building one generic interface to the data store allows the ability to put data into it and get data out of it in many different ways. I'm picturing everything from simple websites with forms and Google Charts, to Ubiquity/Quicksilver commands, to fancy Android apps.

I have a hunch that most of this can be accomplished using existing web services, but I need to research it more.

City Council Race 2009 - Twitter!

I wrote up a post about all the City Council candidates that have Twitter accounts over on the HereInCincinnati blog. Here is a widget containing all their accounts merged into one feed:

Plans for 2009: Mid-Year Update

At the beginning of the year I made a list of things that resembled resolutions for the new year. I had this feeling like I was not doing things as much as thinking about doing things. The list was there so that I would have a place to look during those moments of free time when I think, "I should probably try and do something interesting right now instead of wasting my life away."

Then in March I checked back in to see how many things I'd done, and I was honestly a little bit surprised that I had done more things than I thought I would have. So now I'm checking back in, with the year half gone, so see if I've made it anywhere near halfway through the list.



Making stuff:

Cooking
- GOAL: Cook "real" food at least once per week at home.
- STATUS: Not going so well. I've learned some new recipes that make it easier to cook something that is relatively healthy relatively quickly, but I'm still mostly just making sandwiches and kool-aid for dinner. I'm doing a decent job of staying away from eating junk food at home though.

Bread:
- GOAL: I wish I could get good at making my own sourdough bread.
- STATUS: I started out making a lot of Amish Friendship Bread, and that got old after a while. I started a regular sourdough and made bread with it once. Making bread is a long ( like 15-hour ) undertaking. Recently, after several months of keeping the sourdough alive but not making bread, I finally had to commit some of the sourdoughs to the drain.

Beer:
- GOAL: make beer and root beer
- STATUS: The root beer was fun, but kind of petered out after a while. I met some people recently that brew beer, and I might try and learn from them. I also read recently about making your own mead, so I might consider doing that since it might be easier.

Cheese:
- GOAL: make chese
- STATUS: Haven't made anything. I think I'm going to follow Fankhauser's syllabus where you make yogurt, then work your way up to cheese. I'm not a big dairy person, so I'm not actually in a big hurry to do this one.

Gardening:
- GOAL: Grow food. Possibly hydroponically.
- STATUS: Well, I didn't get my hydroponics set back out, but I did attend a class at Park+Vine called "Your Spring Salad" and got a really great set of seeds and seedlings. I grew several different salad greens, beets, radishes, and onions. I successfully harvested and ate some of the greens and one radish. Most of the plants died while I was in Minnesota for almost a week. Some are still alive though.

Local Food:
- GOAL: eat more local
- STATUS: I had a big project in mind a few months ago and was actively learning a lot about local food systems and was seriously considering building or at least running some sort of local food website for the Cincinnati area, but I think I got kind of burnt out on it. Maybe I need to go back and revisit what I want to accomplish and build some more relationships.

Bison:
- GOAL: visit a bison ranch and possible eat some bison
- STATUS: This is still something I want to do sometime when I have a free weekend and someone to go with. Unfortunately weekends like that are rare for me. There is a ranch not too far from here.

CSA:
- GOAL: join a CSA
- STATUS: I didn't join a CSA, but I did a lot of research and the CSA page on my Cincinnati wiki is far and away the most popular page on the site. I believe I have put together a table of information there that is not available anywhere else. Although it is fairly well out of date now.

Farmer's Markets:
- GOAL: visit farmer's markets more often
- STATUS: I've visited the Green Corner Market several times and visited Findlay Market once since March, although I still have not made it a regular practice.

Recycling Paper:
- GOAL: make paper
- STATUS: Big win. I successfully followed this set of instructions and made several pages of paper. I use a shredder to shred waste paper, then use a blender to blend it into pulp. Then I use a piece of screen to make it into new sheets. The new paper is still a bit rough, but the process basically works. I would like to start making things like greeting cards. I would also like to experiment with adding seeds to the paper.

Crafting / Remaking / Upcycling:
- GOAL: turn my busted IKEA hampers into useful new things.
- STATUS: I successfully prototyped a folding table made from one of these hampers, but it is now falling apart. I need to figure out how I am going to go from cardboard prototype to real, useful table.

Knitting / Weaving:
- GOAL: learn to weave or knit
- STATUS: I haven't really done this at all. It seems like lots of people are into knitting, but not as many are into weaving. I would like to track down this video tutorial I saw one time that showed how to weave. Ah, here it is.

Composting:
- GOAL: create a place to take kitchen compost outside somewhere
- STATUS: I haven't gotten to this yet. I really need to soon though because my under-sink compost container is getting full.

Rapid Prototyping:
- GOAL: have something made by ponoko and/or papekura
- STATUS: I took a design from Thingiverse and sent it into ponoko. And I got back a sweet laser cut bunny. But I (stupidly) scaled the bunny up and it doesn't fit together the way it's supposed to. I might order something else, now that I see how the whole process works. I just wanted to get my feet wet, so I consider that a success.

Making online stuff:

hereincincinnati blog
hereincincinnati wiki
virtual vine st.
diycity
cincymicrocosm
citycouncil2rss
wikipedia photo hunt
cincinnatiparking.info

I'm just going to summarize all of these by saying that I haven't worked a whole lot on any of them. I'm considering working on the wikipedia photo hunt idea some more now that I have a phone with a great browser, gps, and a camera.

New Ideas:

Hackerspace:
- It's hard to believe that 4 months ago the hackerspace was just a twinkle in my eye. A LOT has happened since then. The hackerspace is a real thing. It is a corporation, I'm on the board of directors, and we have signed a lease. We are currently working on raising money and making our space awesome to hang out in.


Local Currency:
- I've had some more ideas on this, but haven't gone out and implemented them. My desire to run an instance of oscurrency has not decreased.

New New Ideas:

Libraries
- Due to several factors intersecting - including the possibility of many libraries closing soon in the State of Ohio - I've been pondering the future of libraries more than usual. Obviously libraries have been struggling with what their purpose is for many years now, but I've started to evaluate what types of alternatives to centralized libraries have become possible in just the last year or so. With the rise of cheap and easy cloud computing, and the maturation of the open-source Koha, I've been thinking that there may be an opportunity to create a community of small-scale independent online libraries. Something like a blog-hosting site, but instead of a blog, you get your own ILS. Still need to think on this some more, but I am going to pursue it and see where it leads.

Screen-printing:
- Via a contact in the hackerspace, I was invited to a crafts night at KHAC hosted by the Cincinnati League of Artisans and I learned that it is really pretty easy to screen-print. I was so excited by it, I asked for (and received) a screen-printing starter kit for my birthday. I have some ideas for some shirts and I may also screen print onto my homemade paper.

Android apps
- Oh yeah, did I mention I have a G1 now? It is really awesome. I've started doing the Hello World tutorials for programming Android apps and I have some ideas for apps that I think I'd like to build if I learn enough. One would be turning the wikipedia photo hunt idea into an android app. Another would be an offline topographic maps application that can be used while hiking.

Kombucha
- I've acquired a starter and brewed several kombucha batches. I'm still learning about tea and haven't made the perfect kombucha yet, but I like doing it.

MakerBot
- I have been lusting over these for months now, and now that I have the hackerspace, I have an excuse to buy one. And I think I've found some people there that will team up with me to build it.

Just Getting Warmed Up

I've surprised myself again with the number of things I've done between March and now. The biggest thing is that the Cincinnati Hackerspace is real. This was (and is) a big project, but the awesome thing is that it will help me do all my other projects. I've found a community of like-minded people and we now have a really nice facility in which to work. I couldn't be more excited.

About Your Cincinnati Public Library

1) In 2008 PLCH was ranked in the top 10 in Hennen's American Public Library Ratings for libraries serving a population of 500,000 or more AND the Main Library branch downtown was named the busiest library branch in the the country. Library use is at an all time high.

2) In March of this year, the Fiscal Office at PLCH was awarded the 2007 Making Your Tax Dollars Count Award bestowed by Ohio Auditor Mary Taylor for being in the top 5 percent of finance directors in the state honored for careful spending, accurate fiscal recording and efficiency.

3) Because Library funding is a percentage of the state’s general revenue fund, as the economy has faltered, the Library’s funding has already been reduced 25% since 2000. The Governor’s proposed state budget is considering a 50% cut to the Public Library Fund, a $6 million FURTHER cut to our Library funding. If this proposed funding cut is enacted, consequences would be DEVASTATING regardless if a 1 mill levy on the November 3rd ballot is passed. This is what you would see in September 2009:

* 250 additional Library jobs will be lost
* 20 branch libraries will be PERMANENTLY closed
* Main Library hours will be dramatically cut
* Computer access will be reduced by more than 30%
* Fewer new books, CDs, DVDs and other materials will be available
* Diminished quality of service and less qualified staff to help

* PLCH's call for Action
* SaveOhioLibraries.com
* The Library Is Now Closed blog

Modeling Displacement via Gentrification

Ok, so the last time I blogged about this was two years ago, but I still think it's interesting and I still have the same questions. I think I've found a better way to illustrate what I mean. I've drawn up some drawings.

I'm going to run through a series of scenarios that could possibly describe what is happening in a gentrifying neighborhood. I don't know which (if any) of them describe what is happening in Over-The-Rhine. I don't know which (if any) of them describe what is happening anywhere. I am not an urban planner. I just want a more concrete way to look at a social justice issue.

Also, here I'm just talking about the issue of displacement, which seems to be one of the biggest stated downsides of gentrification. I'm not talking about other cultural effects on a neighborhood, or other kinds of problems that might occur. I'm just talking about how many people can fit in a neighborhood and who moves out when other people move in.

So, I've outlined two basic situations here. The numbers are completely made up. I don't know what the real numbers are in any neighborhood. I am actually skeptical that anyone knows the real numbers in these situations, and that is part of the point I'm making with this blog post. The numbers I've used here are just to illustrate some of the range of things that could in theory be happening.

We start with a square that represents an urban neighborhood. I've made this one 10 by 10 pixels so that the "capacity" of the neighborhood is 100. That makes it so everything works out as a percent. I recognize that a neighborhood isn't a fixed box and that it doesn't have a fixed capacity. And I understand that the quality of housing varies. Those details are not in this abstract model I'm building here.

In situation A, we suppose that there are 37 people living in the 100 person box. The current residents of the neighborhood are the blue squares. It is 37% occupied.



Now, let's say 16 people want to move into the neighborhood. These are the gentrifying urban-pioneers or whatever you want to call them. The question I am exploring is what happens to the people that already live in the neighborhood when the new people arrive?

Let's say most of the new people move into places that were already empty and 5 of them move into places where other people used to live. And let's say that those 5 previous residents all stay in the neighborhood. I think it would look like this:



Or what if all 5 of those previous residents just move out of the neighborhood? It would look like this:



What if the new people make all the rents go up, or make the neighborhood otherwise repellent or unlivable for the previous residents and a whole bunch of people move out. That would be something we would want to avoid. It might look like this:



The blue number to the right is the number of people that move out due to displacement caused by the gentrification. Assuming that this displacement is a social injustice, then that number is bad. We would rather keep that number small or zero.

Let's look at another situation - again with made up numbers. Let's say that there are 73 people living in the neighborhood. It is 73% occupied.



Now let's say 32 people want to move in. Again, there seem to be several ways this can work out, but right off the bat it should be obvious that not everyone is going to fit, because the neighborhood can only hold 100 people. This is an abstract neighborhood - it has a fixed capacity.

Let's say that everyone that can possibly fit tries to stay in the neighborhood. The smallest number of people that would have to move out is 5. The neighborhood is 100% full:



That doesn't seem the most likely though. Let's say like before that the people who leave their current places just move out of the neighborhood, but everyone else already there stays. Maybe 25 people move out. The neighborhood is 80% full:



What if we make it so that the number of original residents left in the neighborhood is exactly equal to the number of new residents? 41 people move out - over half of the original population. The neighborhood is 64% full:



Or maybe the neighborhood is so different now that most of the former residents move away, even leaving their own former homes empty. The neighborhood is only 54% full. That might look like this:



Remember, the blue number is bad. So, this last scenario is the worst of all.

My real frustration is that I don't know which of the above scenarios is actually happening in OTR. Which do you think is happening? Which does 3CDC think is happening? Which does OTRCH think is happening? Studies have been done in other cities that make actual, factual surveys of neighborhoods where gentrification is happening. Detailed block-by-block surveys and multi-decade record keeping would be necessary to make maps like the ones I made above reflective of the facts on the ground.

The decisions that are being made about OTR development rely in part on a narrative of what is happening in OTR - and everyone has a different way of reading the story. It seems to me that this is due in part to the fact that no maps like the ones I made above can be made accurately. Correct me if I'm wrong.

From the OTRCH website:

"In 1950 approximately 30,000 people resided there, with whites constituting 99 percent of that population. Recent data show about 7,600 total neighborhood residents, 80 percent of which are black. Of the current residents, 95 percent live below the official poverty level of $13,000 annually for a family of four. Of Over-the-Rhine's 7,500 apartment units, 3,000 are below housing code standards and approximately 300 buildings stand vacant."

7,600 / 30,000 = 25.3% That's even less dense than I modeled in my first scenario above. In theory a large district like OTR has room for plenty more people before residents start overflowing, but who knows.

I think the thing most people would want to see is something similar to the second graphic above. The neighborhood is mostly empty -> some people move in -> some other people may have to move, but everyone who was there stays within the neighborhood - no one moves out. The neighborhood is fuller and more diverse.

Reds Home Game Schedule in iCalendar

I recently subscribed to the Reds Home Game Schedule using Google Calendar. Today I noticed a cool feature: they update the games that have finished with the scores, so you can see at a glance how the Reds are doing. For example, the event for yesterday was called "NY Mets at Cincinnati" but now it has changed to "NY Mets 6 - Cincinnati 8". Use this url right here:

http://mlb.mlb.com/soa/ical/schedule.ics?home_team_id=113&season=2009

Put that url into Google Calendar to see what I mean. That's the url for home games, but if you want the complete schedule or the away schedule, you can get iCalendar feeds for those too at their page on mlb.com.

Update: I'm going to attempt to embed the calendar below:

Cincinnati Hackerspace - The Critical Mass Pattern

I'm wondering how many people are interested in this idea of a hackerspace in the Cincinnati area.

It looks to me like there is a kernel of people working to start a local chapter of dorkbot: dorkbot-cinci.

    .___            __   ___.           __         .__              .__

They meet on the first Friday of the month (tomorrow!) at the Brewhouse "crashing the cinci2600 meeting".

I've got a few notes on this topic over at DIYcity on our DIYcity_Cincinnati page, too.

I think there are a number of different flavors of "hackerspaces" that we could maybe try: hackerspace, co-working space, free geek, tool library, free culture shop, crafter / maker hangout.

I think that the Critical Mass Pattern makes sense. I think I'm going to go to the meeting tomorrow night at the Brewhouse and see how I can help. Join me?

Update!: A group has formed (online) to discuss setting up a hackerspace in Cincinnati. Check it out at: http://groups.google.com/group/cincihackerspace!

Platforms on which to build a local food distribution system

I've become somewhat preoccupied with this whole "local food distribution" concept and I've been finding different examples of how folks are doing it in other areas. (I list a lot of what I've found in these previous posts: 1, 2 ).

To my mind there are two big components to a local food distribution system. The first component is allowing local producers and consumers to discover each other. The name I have for this component is the "market". It can take the form of a website or a physical meetup at a farmers' market. The second component is moving the food around the region from producer to consumer. I call this the "T&L" component for Transportation & Logistics. This can range from farm stores where the consumer travels to the site of production, to CSA's or farmers' markets where producers and consumers meet up in the middle somewhere at pre-determined times, up to home delivery where food travels all the way to the consumer's home or business.

For the market side of the equation, I've thought mostly about solutions based on the internet. I'm a bit of a technophile and so that is where my mind turns and I honestly think there is a lot of untapped potential there. There are a handful of solutions that can be used basically "off-the-shelf" to varying degrees. Those would be:

* http://www.locallygrown.net/
* http://www.localfoodcoop.org/details.php
* http://www.freshforkmarket.com/
* http://oh.marketmaker.uiuc.edu/

I know a lot less about T&L than I do about websites, so I have not figured this out as well. In my mind one of the basic problems with farmers' markets and CSA's is the fact that you have to meetup in a certain place at a certain time. I realize that this is probably the simplest way to do the logistics and I'm not trying to knock it. But it does seem like there is room for other types of physical distribution to be tried. What about a CSA pickup point that is limited in location but not so limited in time? Or a system composed of a distribution center and delivery trucks that send food directly to the doors of subscribers? What would the minimum order sizes be? What would be the optimal delivery frequency? All questions I'm not well equipped to answer. I was at first inspired, then disappointed hearing about CityCargo that seemed to have a good idea that ended up being cancelled. It may in fact be that the weekly or monthly meetup is the most efficient way of distributing goods from many producers to many consumers - I have no expertise in the field, so I can't really say.

Locavore iPhone app - anyone in Cincinnati tried it?

I'm really, really, inspired by this new application for iPhone called Locavore. It brings together a lot of cool info making it super easy eat locally:

Features:

* Automatically detects which state you’re in (currently only covers the US)
* Food that’s in season near you
* Food that’s coming in season near you soon
* Farmers’ markets near you
* Browse all 234 fruits and vegetables to see where it is currently growing
* Links to Wikipedia articles and Epicurious recipes from each food detail page
* Browse all 50 states to see what’s in season in other parts of the US

Built with the help of:

* Natural Resources Defense Council for food availability
* LocalHarvest.org for farmers’ markets data
* Tattfoo for colors
* Designed by Matt Hickey
* Integrated with Get Satisfaction Remote for in-app feedback, ideas, and bug tracking

Amazing! But I don't have an iPhone. :( Has anyone out there tried it?

Cincinnati Food Congress - Results?

Did anybody out there reading this attend the Cincinnati Food Congress March 14th?

The possibility of takeaways was brought up on localfoodsystems.org, but I have not seen anything shared or published yet.

I'm interested in what happened since I wasn't able to attend. Were any documents or anything produced at the congress that could be shared / made available online?
