I’ve been wondering whether anyone would implement short range drones for package delivery rather than the fulfillment center to door model that Amazon seems to be pushing.
I’d expect that a drone that flew from the roof of a delivery vehicle to the drop location (door stoop, front porch) of each destination in a neighborhood would speed up the delivery process while requiring much less robust drones than the full range alternative.

I’ve been talking about putting together a RepRap for years now to get rolling on playing with 3D printing.
The M3D Pro seems like a good device for around $500.00 to get some printing done and perhaps bootstrap my RepRap experimentation.
I’m building up quite a list of things that would be helpful to have some editor automation wrapped around. It is always hard to find the time though…they’re mostly small items that take a few minutes to do by hand. Emacs lisp is different enough from the C lineage procedural languages that I’m normally working in that it takes a bit of time to reorient to the environment. Soon though…
It has been some time since I’ve had reason to write command line posix code. I spent a bit of time re-familiarizing myself with the getopt family of functions. The getopt_long function seems pretty serviceable…could do better with a C++ wrapper, but then I’d have to roll my own (or roll a non-trivial wrapper). At this point I think getopt will do the job I need…
seem to be getting weaponized. This item discusses using known shared code pages from one VM to another to force memory corruption using the ‘DRAM hammer’ bit flipping attack modes that have already been well documented as a way to inject hostile code into another (probably all given dedup designs) VM on the same physical machine. This would seem to be a very scary attack for cloud hosting companies.
It would seem like this is the time for DRAM vendors to take a close look at their designs and start making serious attempts to implement resistance to this sort of attack. I do wonder whether ECC would prevent this as the bit error might be corrected before another error could be introduced.

as a place to make sandbox projects broadly available.
GIT is my preferred sandbox source code control system these days. Github provides wide visibility and the potential for collaboration should anything grow beyond the sandbox.
In the past I’ve just kept them local with no sharing. As I’m trying to make more of who I am and what I can do visible on the web, adding any interesting sandbox code I create to <a href=”https://github.com/”>Github </a> is the most effective way I have of getting this done.
So far there isn’t anything stored up there, but over the next few weeks I’m expecting to get some things rolling.
Starting to look at getting my http://ninecrows.com base URL pointed at my landing page wordpress instance at http://ninecrows.com/landingpage (artwork to support the landing page will come later).
I’ve been reading (and buying in kindle form) a bunch of material related to the front end of web development. I can created serviceable web forms and simple applications but I want to take this up a notch or two.
3D programming is also on my (often too long) list at the moment. This covers a huge range and I’m not sure where I’ll wind up looking first. A full OpenGL implementation with a RESTful back end into the PHP site is a possibility. An android app using OpenGL ES is also possible. Probably easiest (and thus most immediately likely) would be a WebGL implementation (thus the focus on javascript and related bits).
I would like to get the site landing page roughed out and in place this weekend. Currently http://ninecrows.com just drops you on a plain HTML page with text on a background and some links. I know mod-rewrite rules can re-point that reference to a sub-folder. I have installed a target to catch those requests and expect to configure this to serve static wordpress pages. If all goes well, I’ll have something in place there by Tuesday.
I’ve fleshed out and enhanced the book shelf area. Still not particularly structured but it now has thumbnails for all of the books and I’ve added comments on more of them. I still need to add comments to much of the newer material and perhaps rearrange the lists to be more usable. It have been an interesting dive into my books list as I ran across a few items that I had bought out of curiosity and never found the time to give real attention to. I’ll have to remedy that soon.
I want to tackle the ‘things I’ve worked with’ list on this blog next. It is currently just an expanded version of the key word list from my resume. It needs expanding (and I guess my resume list needs expanding as well then) and it needs organizing. I think I may go to a category based setup with ‘languages’, ‘operating systems’, process and such.
Sandbox projects keep getting postponed due to work and life time crunches. Not looking much better in the near term future, but I’m going to hold out hope.

st grabbed a copy of ‘Building web apps with WordPress’ for my kindle app. I’m really looking seriously at building shared information applications with my site in the middle. I need to substantially improve my command of the UI side of web apps and this looks like it may hit that and some of the back end issues that would help me get leverage from WordPress rather than writing code from scratch.
I’ve spent a few evenings rummaging around the web, looking for interesting tools and code that is either coded in java or runs on the JVM. There is a lot of material out there. I had been discussing other programming languages with a friend a little while ago and lisp was mentioned. That got me thinking (and clojure as a functional programming oriented lisp dialect particularly got my attention) so this list is currently a bit lisp heavy.
There’s much more out there and I’ll probably wind up wandering through it as time passes. I’ve grabbed snapshots of these projects to mess with. Depending on time and momentum I’m likely to poke at Clojure and perhaps a bit at some of the other lisp dialects. I haven’t messed with lisp in a long time (and most of what I have done was gnu emacs lisp) but it seems as if a few interesting things are going on there. A functional programming environment that can be used in conjunction with other methodologies is also very interesting. I can’t see doing a majority of the things I do in functional land, but having the option of doing tasks that are well suited to that approach using a functional environment is quite interesting.
