Wow ppl..... I just wanted someone to enlighten me about how to programmatically retain wire values. in my wildest imagination I never conceived that it would end up invoking murder for breach of copyright.... hope it never comes to that!

I'm going to learn LabVIEW. So I can come to NIWeek with you.

That's a well hijacked thread indeed!

I'm not crazy; my mother had me tested!

Well. Leaving aside the economic arguments for now..... The big thing about bitcoin is there is no centralised accountancy, it is almost an instantaneous peer-to-peer transfer. And it is extremely hard to trace (anonymity). A few years ago you might argue that the latter was only a benefit to criminals. With current events (SOPA, Snoopers Charter et. al.) many ordinary folk feel that they need to protect their privacy. Many economies are also being sucked dry by corporate interests and other monetary systems have arisen to combat this so people are looking for alternative strategies. Bitcoins are gaining popularity mainly because of these two points and you could say it's filling a need at the right time. Bitcoins obtain their "value" from scarcity (limited maximum number of 21 x 10^6) and by the energy consumed in generating them (electricity to run a bitcoin miner). There are a couple of bitcoin "exchanges" where you can convert bitcoins to fiat which is probably a more understandable, although flawed, measure of value (as of writing 1 bitcoin~= 14 Euros). ...... But on to the interesting stuff ...... Bitcoins are "mined" (that's the terminology) just as resources (like gold) are. Instead of digging a hole, however, a computationally expensive algorithm (a hash) is used by a Bitcoin Miner. This is synonymous with password "cracking" in computational terms, but the intent is quite different. Whilst in the early days you could mine with a fairly low spec PC. The "difficulty" has progressed to the point where you now need dedicated hardware-usually racks of GPUs in the 10s of Giga-hashes per second. (This has led to an argument that early adopters gain a significant wealth advantage, but let's stick to the interesting stuff ) The design of the bitcoin system is such that there is a maximum of 21 million that can ever be created (currently there are approximately 10M in circulation). A bitcoin itself is just a history of transactions (the block chain) from the "base" bitcoin block and the difficulty in "cracking" the hash changes in relation to the rate at which bitcoins are mined. (I should also point out that bitcoins are not mined singularly, but in batches). The number of coins in the batch (currently 50 at this time) also reduces as more bitcoins are mined meaning that the cost/BC (electricity consumed) increases with more bitcoins in circulation. You can get a more concise overview here. Suffice to say. On the surface it looks fairly straightforward (just money, right?) but the deeper you go, the more you realise just how much thought has gone into the system and how technically elegant it is (and not a banker in sight!). I can see a couple of issues that need to be resolved (bitcoins can be destroyed but not recreated and defence against a party taking over 50% of the network). But it does look very promising and certainly has gained the attention of the authorities.

To be honest, I'm not sure about my position to Bitcoin itself. I tried to understand what it was about by visiting the forum there, but don't really got a clear picture. From some of the remarks there, it seems to be used by some folks in somewhat questionable ways. But then anything that represents some value in some form, even virtual currency or items in online games, is quickly attracting some folks who have more than questionable intent. So that alone is certainly not a criterium if the the idea of Bitcoin could be considered legitimate. However it seems to me some form of online virtual currency that only exists by the gratitude of people believing that it represents some value. That in itself is an interesting concept and in fact not so much different than even our official currencies we pay with all the time, and probably even more real than derivatives on stock exchange markets. However who controls the creation of that value? In other words how are Bitcoins created? And I'm not so much interested in the technical details here as is already mentioned in this thread by the formula, than the process and procedure that controls the creation. If it could be created by anyone in any number it would obviously loose all value.

To the best of my knowledge, the answer is "no". We've had the XStructure on the drawing board for almost a decade but no one has gotten around to building it. There's minimal impetus to do so... the number of control structures that we've built into LabVIEW over the years has been fairly small -- they still fit in one palette. Very very few ideas are put forth that call for a new flow-control structure, so no one has felt compelled to build the G mechanism for defining one. I suppose in theory you could build up an XNode that draws a very complex inner image and maintain all your own editor state operations for the fake diagram inside your node, but the work involved would be excessive in the extreme. If you look at the Sim.xnode, I think you'll find a bunch of stuff that isn't actually implemented in G. I know, for example, that their whole interior is back in the C++ code. I don't know how extractable that layer is for a different XNode.

In LV 2009... If you want to add customizations to the new VIs that are created by New>>VI For Override and New>>VI For Data Member Access, you can open and edit these three VIs. These VIs are called at the end of their respective scripting processes and you are free to include any scripting code you wish to further customize the VI in question. Some common customizations you might want include changing the VI name (use "get" and "set" instead of "read" and "write"), modifying the icon, adding additional diagram logic, etc. You cannot edit the callers of these three VIs, but these three provide the hook you need to customize your new VIs as you want them. Customizations for Override VIs: <labview>\resource\Framework\Providers\LVClassLibrary\NewAccessors\OverrideRetooler\Custom User Scripting For New Override VI.vi Customizations for basic accessor VIs: <labview>:\resource\Framework\Providers\LVClassLibrary\NewAccessors\BaseAccessorScripter\Custom User Scripting For New Simple Accessor VI.vi Customizations for 1D Array element accessor VIs: <labview>resource\Framework\Providers\LVClassLibrary\NewAccessors\ArrayElementScripter\Custom User Scripting For New Array Element Accessor VI.vi Customizations for multi-dim array element accessor VIs: <labview>\resource\Framework\Providers\LVClassLibrary\NewAccessors\MultiDimArrElemScripter\Custom User Scripting For New MultiDim Array Element Accessor VI.vi This is for the various LAVA folks who asked these scripting hooks be added.
