There's a tool called PRET - the Printer Exploitation Toolkit -- "the tool that made dumpster diving obsolete" -- that some of you might find fun and useful. You can use it to test which print protocols (ps, pjl, pcl) the printer uses, and then send files to print directly using one of them. It has a bunch of other interesting functionality too.

Where are all the printer firmware hackers at?


Very likely, there is secure boot.


That was the previous idea, but this work changes that. It implies that the cooling rates of meteors is actually much faster than previously guessed.


other than friction or the sun adding heat, why would they assume that it would take so long for it to cool down?


I assume it's because there's only so much of that heat that the globs could radiate into space as (infrared) light.

Maybe someone familiar with the intimate details of blackbody radiation could chime in here?


This is exciting stuff for MatSci people. There are likely other interesting materials that could be made using this process, including the other alloys found in iron bearing meteorites. I expect that the process can be modified and extended.


FWIW, iron reduced in hydrogen is known to have a very high magnetic permeability, surpassed only by one of the Metglas alloys.


Okay, three questions, if you'll humor me: What LISP resources particular to AutoCAD would you recommend, what are your favorite scripts, and for context what do you do / use AutoCAD for?


1 & 2: Best generalist lisp routines were natively included along the years. So "lisps" (as non-tech guys call autocad scripts), nowadays, only make sense to answer to custom needs. You can be sure that any architectural office have plenty of stuff (design related) that could be gladly optimized/automated. The problem is that they rarely have a person (or the budget) to do it.

3: I'm an architect (housing kind).

Newbies use to hate Autocad. I hated it in the beginning also. It will take at least a couple months until you start to get some profits from it. A couple years to get proficient.


Update: I found a solution to a particular problem, representing twisted pairs with bends in a cable without the hassle of sloppy line thickness settings, or making sure every bounding area is perfectly joined and closed for hatch fill: to do it in Solidworks instead ('fit spline' FTW!) and export to dwg... lol
