I’m really having fun inventing new objects with my 3D printer. Much more on this shortly.

JPIV Throwing Exceptions
If you are trying to do some particle image velocimetry, and JPIV starts, but throws exceptions, you probably need to install the Java Advanced Imaging Library (agh!). This is because Java Webstart, despite it’s best efforts, cannot install the JAI(L) automatically.
I installed all three installers from this page, which is a pain to find. After that, the errors stopped, and the velocimetry began.
Much of my career has revolved around Java/Android/Webstart projects. Why is Java still such a horrendously high-friction thing? It’s sad.

Details Inside
I’ve taken to placing a schematic inside of electronic devices as build them. This was commonplace in consumer electronics up until the late seventies, but was replaced by the ubiquitous “no user serviceable parts inside” label. Utter bullshit. Anyhow, this simple technique keeps me from having to look things up, even though looking things up is usually very, very easy. In this particular case, it keeps me from having to log into an obscure and poorly managed Yahoo Group. Aaahhh.

Brother HL2270DW Toner Cartridge Reset Procedure
Have a Brother HL2270DW laser printer. Great printer, except that the starter cartridge lasted a measly 210 pages.
First, I tried this. Which didn’t work.
Then I ordered these inexpensive replacement cartridges from Amazon. Wish me luck.
Then I found this solution, which works. The post, originally by Phiolle, says:
Please do the following steps to reset the toner sensor.
- Open the front cover and leave open while completing the following steps.
- Turn the printer off.
- Hold the ‘go’ button while turning the printer on. All lights should be on.
- Release the ‘go’ button (or “start’ button).
- Press the ‘go’ button (or “start’ button) 2 times.
- Pause. All panel lights should be on.
- Press the ‘go’ button (or “start’ button) 5 times.
The toner light should be off. (error may be flashing)
The paper light should be on or flashing.
- Close cover. The ready light should be the only light on.
It works. Quoted here for posterity and google-ability.

Hakko 936 Fix
I have a Hakko 936 soldering iron. The base unit is factory original, however the pencil is from eBay. As it turns out, the pencil is either a factory reject, or it is a counterfeit.The knurled section on the bottom did not mate with the section below – the threads were too large. I’ve suffered this for several years, simply pressing it back on to the base after it pops off. However today it annoyed me enough to necessitate a fix. I I drilled two holes through the outer knurled section, and inserted two self tapping screws. I also wrapped a band of copper wire around the base to prevent the two screws from becoming a cantilever upon which the tip could pivot. Works beautifully. Now I can get back to real work.

The Lockpicking Possibilities Intrinsic in Hard-Wear Plastics
Night is rarely so revealing as with light. 
The total combination space of a new lock is huge – orders of magnitude, exponents. Log scales. Billion combinations. But a code never changed wears itself in. Specular reflection will buy you access when even the heat of a hand has faded.

Things That Won’t Exist For Long
Opened up a television today and found this “User Manual”. I was surprised at the sheer number of languages represented. In an age of smartphones, there should be a single block of digital data in the middle that auto-translates to all possible grammars. And a human-readable, machine-translatable text version from a single ur-language like Mandarin or English.
I can see a strong case for a new breed of diacritical mark – one that helps machines disambiguate difficult grammar.

The Ultimate To Do List
No question about it, workflowy is the ultimate online to do list.
Do you do things in your life? You should use it.
I use it constantly and paid for the pro version so I could share lists with friends.

Twenty Twelve; Thirty One.
2012 is, roughly speaking, over.
It was equal parts sunset and surprise.
I learned about wishing. About wanting.
About the meaning of preparedness; about always being ready. 
But I couldn’t expect this; my expectations were too low.

Blame that on a lot of things, most of all myself.
But the flip side of blame is credit. I wear the marks to show it.

Yes, I made this happen, a few hundred times.

Yeah, I can claim credit for a lot of things. But what is the value of this -

I thought I knew, but – I didn’t. Couldn’t.
I thought I knew about ties.
Not really. Turns out it was all better than I expected. Easier. Faster. Clearer.

some dumb luck, and a sixth sick sense of enjoyment,
Justice, self served, soft-served

Better than I expected. Deeper.

Yes.
