I'm not about to break a streak.

It's getting near the end of September and I haven't posted anything yet this month. What's going on?

Rather a lot, actually.

I've taken on a significant amount of responsibility at my day job this year, and sometimes that means putting in long hours. Long enough hours that, if I don't faceplant shortly after arriving at home I'm awake for only an hour or two afterward, and the last thing I want to lay eyes on is a keyboard. I usually study during that time before crashing for the next day. Yes, this means that I'm at the point in my career where racking up certifications is now a requirement, and not merely an idea to entertain and then set aside for later. This is not terribly conducive to blogging, as one would guess.

I've also been putting in a fair amount of time working on a couple of conferences, both organizing and preparing papers for. Organizing a conference seems so easy when all your're doing is preparing and practicing a presentation, and maybe running your paper past someone for a final look-see before it goes live. But when it comes to getting everyone to send their presentations to you in a timely manner for testing, getting a laptop and projector, figuring out lunch for all the attendees... it's a lot of work.

I have a fairly large queue of stuff I want to write about, probably fifteen or twenty long-form posts worth. If and when things calm down somewhat (and assuming that my body's immune system doesn't segfault on me) I'll try to get to work on them.

UPDATED: I'll be presenting at the Future of Politics Conference.

EDIT: While I will be attendence at this conference, I am no longer in the lineup of speakers.

On 18 October 2015 I'll be presenting at the Future of Politics Conference held by the Brighter Brains Institute. I'll be giving a talk (which doesn't have a title yet, and in fact I have yet to start writing) on tools and strategies for grassroots organization in a time when we're all connected on a 24x7x365 basis (which is to say, today).

The conference will be held at the Humanist Hall in Oakland, CA from 10:30am until 6:00pm. Lunch will be served. Tickets are available through Eventbrite.

DefCon 23: Presentation notes

Here and behind the cut are the notes I took at DefCon 23. They are necessarily incomplete because they're notes, and I refer you to the speakers' presentations and eventually video recordings for the whole story.

DefCon 23: The Writeup

Well, I'm back from DefCon in sunny and hot Las Vegas, Nevada and more or less reinserted back into my everyday life. I'm just about caught up on everything that happened at work and finally finished the notes that are going to comprise this article. I'll type up the notes I took during the talks at DefCon in a couple of days; they've voluminous and I want to get the experience out of my head and into external storage before the memories fade much more. Unfortunately, I didn't make it to any of the villages so I don't have anything from those. I'm told that at least a few of the village talks were recorded and will be posted to the DefCon Media Server in a month or two.

My flight to DefCon was pretty standard, I caught my first flight to Los Angeles and got to my connecting flight just as it started boarding. An hour later I was on the ground at McKarren, found my luggage on the carrol, took the 104 degree Fahrenheit sledgehammer to the face that is Las Vegas in the afternoon, and caught a shuttle bus to the hotel. Unfortunately I'd arrived too late for DefCon's opening ceremonies or Thursday's presentations so my plans consisted of meeting up with everybody and figuring out what to do next. I wasn't able to check into my hotel because Genetik was at dinner with the keycards and Seele hadn't landed yet. Rather than get stuck in a pickle I caught the Vegas Monorail to Bally's and then stumbled around for most of an hour in the thing-that-pretends-to-be-the-city-of-Paris trying to find the restaurant everybody was at. Even enlisting help from other congoers didn't help because we were all equally lost. It was a stroke of luck that I found everybody when I did, though I'll admit that low blood sugar didn't help. The late afternoon was spent catching up with Vlad, Sam, and Genetik, whom I haven't seen in quite a few years. Seele joined up with us later after her flight touched down. Dinner out of the way we headed for DefCon proper to pay admission on the theory that the line was still unreasonably long. Last year, I stood in line for several hours before finally getting a badge but this year a combination of new attendee badging tactics and the late hour resulted in getting into DefCon in less than ten minutes, most of that walking from the restaurant to the front desk.

I then received a phone call from some of my cow-orkers who were attending DefCon with me - they ran into problems checking in, and was there anything I could do to help? As it turned out there was a mixup with the length of the room reservation and some coaxing of the front desk (coupled with the judicious use of a fax machine (surprisingly, people still use those)) got them their room keys and into their room with a minimum of trouble. Some time was spent on hold and a little explanation later, and all appeared to be well with the world. All of us met up once again for a late night snack because most of us were still not quite ready for bed (or fueled up from the flight) and then turned in for the evening.

Back from DefCon 23.

Back from DefCon 23 in Las Vegas, NV. It'll take me a couple of days to do my usual writeup and then put my notes online.

I'm alive. Sit tight.

Fabbing components, parallel processing with rats, and synthetic neurons.

Life being what it is these days, I haven't had much time to write any real posts here. If I'm not working I'm at home studying because I'm back on the "get letters after my name" trail, and if I'm not studying or in class I'm helping get family moved out and set up on the west coast. Or I'm at the gym because I'm fighting alongside my essential vanity by trying to lose weight; people tell me that I look good these days but there's a fine line between looking healthy and needing new clothes. So there you have it, from the depths of my psyche just above some of the interfaces.

I do have one or two interesting things in the pipeline that I need to write about - in fact, they're going to be submitted to a couple of conferences if all goes according to plan. But I think I'd better get the conference papers written first because you never can tell if the organizers will pitch a fit (or threaten legal action - they're being held in the US, after all) if you blog about something you're going to present. But enough about that.

Some years ago, after the field of 3D printing really took off, a number of hackers began working on the problem of fabricating circuit boards with 3D printers instead of going through the process of laying out and etching circuit boards with chemical processes that are often nasty and messy. But then the question of acquiring components comes up - Radio Shack is as dead as Walt Disney so it's not as if you can jander down to the strip mall and pick up the parts you need anymore (mostly - some Micro Center outlets have entire sections dedicated to this sort of thing, as do Fry's outlets) if you really need something for a project and can't wait to order it online.

A couple of days ago research teams at the University of California at Berkeley and the National Chiao Tung University of Taiwan published a paper last week in Nature's open access journal Microsystems and Nanoengineering which detailed how they used a 3D printer to fabricate reasonably standard electronic components. Their 3D printer was a dual extruder model which laid down successive layers of structural plastic and sacrificial wax to form hollow spaces inside the figure that were later cleaned out to make room for multiple injections of silver paste which formed the conducting portions of the components. The hollow spaces were engineered to have certain electrical properties so that different kinds of components could be constructed, among them inductors and resistors. From these basic components electrical circuits were constructed; as a proof of concept the research team built a "smart milk cap" which had what amounts to a simple lab-on-a-chip to keep tabs on whether or not the milk in the carton had gone bad or not by analyzing changes in the electrical properties of the milk. Data was transmitted from the smart milk cap via a passive RF transmitter that blipped out data whenever an RF probe energized it.

The size of their components? Before cleaning them up they fit comfortably on top of a penny with room to spare. The resolution of their printer (a 3D Systems ProJet HD 3000) is 30 μm or 30 millionths of a meter. This ain't your dad's breadboard.

Notes from the Transhuman Superpowers and Longevity Conference - 12 July 2015

And now, hopefully sooner than the last set, my notes taken during the Transhuman Superpowers and Longevity Conference held on 12 July 2015 in Oakland, CA. Everything's behind the cut, with references as applicable. Personal observations (are on separate lines in parenthesis) to differentiate them from the speaker's material.

Notes from the Transhuman Strategies conference, 21 March 2015

At long last, here are my notes from the Transhuman Strategies conference held by the Brighter Brains Institute on 21 March 2015. It took me a while to find the notebook I wrote them in, so that's why they're a few months late in coming. Anyway, my notes are under the cut.

I am this week's special guest on the More Thank Bits! podcast.

Last week Alexius Pendragon invited me to be the special guest on the podcast he co-hosts, called More Than Bits! During the interview I fielded a bunch of questions about the RaspberryPi and my lunchtop, Squeak and Scratch, capture the flag competitions and Project 2 by dirtbags.net, Project Byzantium, and being on the Global Frequency.

I was unfortunately ill-prepared for the interview because I ran home from work and jacked in without taking the time to get my head or my notes together, so I made quite a few gaffs. I hate it when I'm operating half in work mode and half in home mode, which messes with my memory retrieval mechanism. Truth be told I'm kind of embarassed by the mistakes I made, but that's what happens when you don't take the time to switch out of work mode. Neither am I perfect.

Here is the episode in its entirity, for listening online or download.

The OPM compromise and information dynamics.

If you pay attention to the news, you've undoubtedly heard that the US Office of Personnel Management, which coordinates the background investigations for every civil servant and contractor of the United States government was pwned so thoroughly that the intruders even got into E-QIP, the online web service that prospectives have to enter their life histories into (well, at most the last decade of it) so the process can begin. Say what you want about government, but this will probably go down as the most gigantic clusterfuck in history and it shows every sign of getting worse, not better. One of the things the US government has gotten incredibly paranoid over since 9/11 is people who aren't USians, almost unto xenophobia. So why, then, did they outsource their entire IT infrastructure management to mainland China?

I got nothin'. And that's not what I wanted to write about, actually. What I wanted to write about is how wrong-headed the idea of "Tell your security officer everything, because if somebody tries to blackmail you about it you can go to them, and they'll help."

The California t-shirt conspiracy.

All of the t-shirts commonly available in California seem cut to make you feel bad about yourself. No matter your self-image, no matter your body shape or configuration, just about any t-shirt you find is going to make you feel fat. At the very least, most sizes run one size smaller (i.e., what is marked 'large' is actually cut as a 'medium', and so forth).

Upon reflection, this might be why personal exercise is so common in California.

Makerfaire 2015

If you've never been to Makerfaire, it's a rite of passage for geeks of all kinds. In fact, I'd recommend that everyone attend their nearest Mini-Makerfaire at least once because you'll see all manner of weird, wonderful, and inspiring things on display. I ran a table at the one in Silver Spring, Maryland back in 2013 with HacDC and had a ball. Anyway.

I had a chance to attend the original Makerfaire in the Bay Area a few weekends ago and, though it was a significant journey on BART and on a shuttle bus it was well worth it. There, I saw more kinetic art than I've seen anywhere else (most of it breathing fire), several examples of functional powered armor, TOOOL had an entire tent dedicated to locksport, there were robots running around all over the place, a massive store where the latest and greatest smart components could be bought (I didn't buy any - I don't have time right now, so there was no point), movie props... more than I can really recount here. I did take pictures of most of it, though.

Here are the pictures I took.

Experimenting with music.

When screwing around with a keyboard try using your off-hand predominently. I find that this bypasses the logical part of my brain which insists that I'm wasting my time and should do something more worthwhile.

Baycon 2015

Once, when I was quite small, I had an opportunity to attend a science fiction convention in Pittsburgh, Pennsylvania. I don't recall exactly when this was, it was long enough ago that Time Trax was on television and still in the first run of its first season (there was merchandise for it all over the dealers' rooms) but it made an impression on me. First, there were other science fiction fans out there, and second there was this thing called cosplay which I didn't really get into until college.

Long story short, I'm finally settled in enough to consider going to any cons in the Bay Area. My search agents caught wind of Baycon, the Bay Area's sci-fi convention which was held a couple of weekends ago. A few months previous I set about making plans to attend, arranging for time off, making reservations, putting out feelers and suchlike. Amberite responded during this process because he was going to be driving down to California around that time. As we are wont to do we'd made plans to dress up for most of the convention. We're both in the Homestuck fandom (and I don't have any of my other costumes left due to multiple clothing purges during the move) so he and I opted to attend as two of the characters, Rose Lalonde and Kanaya Maryam. Amberite already had plans for his costume, which left me getting back into the swing of using my sewing machine.

For those of you who aren't interested in costume making, here are the pictures we took at Baycon. For those of you who are interested I'll put the costume build after the cut...

Ever have a week where you work 16-18 hour days, five days straight?

There almost wasn't enough coffee on the west coast to keep me going. Almost.

Sorry, everybody else. It was for a good cause. Promise.

Yes, this really does happen sometimes.

Sometimes, in San Francisco, a band will appear out of nowhere and play for an hour or two under somebody's eave, or on a corner. No rhyme, no reason, just because. This particular band played jazz for commuters on their way home that night.

A random band playing jazz in Oakland.
