5.0 out of 5 stars Cheaper than Space Pen Plus Stylus, September 14, 2014
Verified Purchase(What's this?)
It is what it says it is. Writes like a pen, stylus works. Cheaper than Space Pen. I carry a pen at all times, even when running. Gave it five stars because it is totally as advertised. It's longer than is convenient for me and an bit of a nuisance, but I cut the clip off. It's way, way to bulky for me to clip on a key chain. Haven't had the caps come off, but it's a pain to keep track of one, the pen I use briefly, but the stylus can get a workout from time to time.

2.0 out of 5 stars Good for the Author's Clients, September 2, 2014
Vine Customer Review of Free Product (What's this?)
Two stars because it's largely a limited treatment of non-original material better covered elsewhere.

This book is probably a good choice for clients or students of the authors. It naturally offers the author’s approach to solving complex problems. It would be difficult though, for someone unfamiliar with the concepts to read the book and apply the concepts. With perhaps a few minor exceptions, such as the use of the terms “Conceptigon” triad, “harmony, variety and parsimony” there is nothing new. For a far more comprehensive coverage of the material see Peter Checkland’s 1999 book, “Systems Thinking, Systems Practice.”

Basically, this is offered as a book about solving complex or existing “systemic” problems, where “systemic” goes beyond “system” by including such as owners. The assumption is, and it is a big and common one, that by breaking an existing system down into its component parts, the “real” problems and solutions to problems will be clear. This book is about the author’s approach to decomposing systems. It does not cover developing, testing or implementing solutions. It does not cover “evaluation or analysis of alternatives,” a classic part of system problem solving. It does not cover “system design.” It does not describe the advantages and disadvantages of the author’s preferred techniques compared to others.

Systemic Thinking offers two “concepts,” the “Conceptigon” and the “Systemigram.”

The Conceptigon consists of seven sets of three related terms that should be used to think about any “system.” “So why 3,7, 21? Why not?” (p 36) They are: communications, command, control; emergence, hierarchy, openness; transformations, inputs, outputs; function, structure, process; boundary, interior, exterior; harmony, variety, parsimony; and relationships, wholes, parts. People with prior exposure to system concepts will recognize either the exact terms or the concepts.

The “Systemigram” is pretty much an entity relationship diagram (ER) without the rich notation and formality. (check Wikipedia) The tool is useful, even powerful, just not original and the author’s “Rules and Principles” description is confusing: “The principles that govern the architecture of a systemigram are identically those that govern inspection of an SoI [System of Interest] using well founded system concepts…With each of these concepts, we can, via the notion of equilibrium, associate tow more, thereby making seven sets of triples…Thus, when we browse the SoI description prior to designing a relevant systemigram, we cannot but notice, for example, parts, relationships, and wholes, and inputs, outputs, and transformations. ..But we cannot also fail to observe the forces of variety and parsimony at work to produce harmony, and indeed haierarchy, openness and emergence. ..First, the nodes in the systemigram are always nouns or noun phrases. Naturally not every noun in the SoI description appears as a node. Parsimony helsp us choose only those entities tha appear to be most significant. However, once a node, that noun phrase is unique in the systemigram and cannot be replicated. So therefore, everything that semantically attaches itself to that noun phrase in accordance with the text must be accommodated in that single appearance. However, not everything that could be said is chosen; only those most significant expressions and relationships with other noun phrases, so chosen as nodes, are present in the diagram. Attaching significance is a matter of sound judgment by th e systemigram creator, aided and abetted by the sound writing of the author of the SoI description. The arrows must not cross one another…Some nodes can be made to include other nodes…This kind of convexity supports, for example…on occasion, an arrow can pass through a containment node, thereby circumventing a crossover…. (pages 162 and 163).

All this being written, understand that the authors may be excellent, even exceptional at working with clients to break down their complex systems and gain useful new insights. If you’re going to work with the authors, it would be good to read the book. Otherwise, pass.

If you’re really interested in a comprehensive academic treatise, Checkland’s previously mentioned text is outstanding. If you’re interested in a classic “systems thinking” overview, try Weingberg’s very readable, “An Introduction to General Systems Thinking.”

5.0 out of 5 stars Works on Flies - Amazing, September 1, 2014
Verified Purchase(What's this?)
Bought this for the safety but was shocked when it worked on black flies. I spend a couple of weeks a year in the western end of Lake Erie and the flies can be wicked; they will draw blood right through clothing, especially socks in the lower ankle area. DEET products are fractionally effective, maybe in the 50% range when you first put it on, but this stuff was 100% effective for a couple of hours each time I used it. Sorry, haven't had a chance for a good mosquito test yet. Didn't notice much smell.

5.0 out of 5 stars Excellent Features, Image Quality, August 20, 2014
Verified Purchase(What's this?)
25 minutes to install. 15 minutes with the manual, though mostly intuitive once you know basically what the buttons do. Was able to slip the wiring under the headliner, across to the door, between the headliner and the "A" pillar trim without removing the trim, inside and down the door gasket, up under the dash to the power (cigarette lighter receptacle). I did use a plastic molding removal tool so I didn't scratch anything (Astro Pneumatic 4505, Amazon)

The manual's a tad awkward, but nothing major. The only thing to understand that isn't clear in the manual, is when you plug it into a computer, all you get is access to the memory card, there isn't any special software or features that will show up on your computer. All settings are done on the camera.

Amazed at the image quality, especially at this price. Only downside is you have to make some decisions about what data you want to capture with the images, not an issue for me.

Added: The manual recommends Class 4 memory and I've tried the camera with Class 4 and Class 10. It records images the same with both. I am not able to connect a USB cable directly to the camera with a Class 10 micro SDHC card and download or view files though that works with a Class 4 card. Removing the card, installing it in the usual SDHC adapter, in connecting it to a computer allows the images to be viewed and played.

The image resolution is amazing, but can't be appreciated on a typical computer screen. Project them on a large screen TV if you want to see the details. Also had an opportunity to drive at night, on unlit, rural roads on an island; again, amazing images. I will try to post a capture of a night shot, but you really have to see the images you get for the price.

Update: One problem, this is generating static noise on AM radio, no problem with FM. Tried powering it with a filtered USB adapter instead of plugging it directly into the cigarette lighter but it didn't make any difference.

5.0 out of 5 stars Well Made, Good Value, Functional, August 19, 2014
Verified Purchase(What's this?)
This comes in one size, and I'm guessing that it's fine if you're anywhere from 7 1/4 to 7 1/2, though if you wash it or get it wet the 7 1/2 is going to feel tight for a while. No idea what the significance of "pigment dyed" is. I have these in two colors and wear them to run in the sun. I've also washed them both. They're solidly made, the colors don't bleed. 100% cotton, not waterproof. They shrank a bit on washing, but stretched back. No metal parts to rust or corrode.

it is what it is. Filter for 2003 Miata. Seemed odd that locally only the dealer had them and that's a 15 mile drive and twice as much.

5.0 out of 5 stars Amazing, It Works!, August 10, 2014
My TomTom 2535 has been flaky for about a year, never occurred to me it was the battery. The video that comes with the battery is on YouTube so you might want to see what you're getting in to before the purchase. Opening the case can be frustrating; it is with all these electronics unless you do it all the time and I don't. Stick with it. Start from the bottom where you've removed the screws. There are three "catches" on each short side and four slightly different ones on the top. The plastic spudger works and it is all you need, though I found it works best sort of backwards from what seems intuitive. You'll figure it out. Once one catch finally gives, the rest are easy.

Because of the way the wiring on the battery goes, you do have to unscrew the circuit board as the video shows. Note that under the top edge it's held down by clips. Note too, two of the screws are different, machine screws so note where each screw goes.

As soon as I plugged the battery in, the TomTom booted and is completely back to normal. All my "favorites" still there. I'm impressed.

2.0 out of 5 stars Not Dark Enough In Bright Sun, August 5, 2014
Basically these are very dark, narrow sunglasses. Most of the time they're effective, but facing the sun with a clear sky with my eyes closed, it is still uncomfortably bright. I covered the lens with duck tape.
