I have just been watching a shed-load of videos on Eliptic Curve Cryptography and Distributed Hash Tables. May seem like a strange combination, but there ya go. Where they even aimed at a LabVIEW programmer? Nope. Where they of different depths and breadths? Yup. Where a lot of the things they talked about way over my head? Only until I looked at more videos and academic papers to fill in the gaps. Would I be thinking about the networking system I have buzzing around my head if I didn't have access to those videos? Not a hope in hell! One video required me to watch 5 other videos and read 7 PDF documents from NIST and various Universities to understand some of the things they were talking about. Maybe one of your non-general and targeted presentations would be, or has already been,, a similar starting point for a journey of discovery.for someone.

Hmm. In that case. I'm not sure any context can be given for an in-joke no matter what the medium. It is quite likely that of a room of people, not everyone got it anyway. Differences between presentations? I'm not sure that is relevant. It is what it is for who it was intended for; presenters change their talks all the time. It seems a bit harsh to say no-one can benefit outside the club because the presenter has to be more careful with their language. It's not as if it was being surreptitiously videoed without the presenters knowledge for a sting to catch them out.
-
Can you put more meat on this? What is the imperative for downgrading? What issues does it address? What are the likely side effects?
-
Presentations are self contained with a title. They are from a "LabVIEW CLA summit". What more [context] is there? What exactly is your worry if it's not the feelings of the presenters or the availability to non CLA programmers?
-
No. I hope you are just being facetious. As an aside. What happened to the VI shots podcasts?
-
Local user groups don't have any barrier to entry, as far as I'm aware and some are talking about videoing them because of Marks sterling work. Is there a point in there somewhere or were you replying to someone else? I was pointing out that the issue is elitism, not financing or dissemination and you seemed to be arguing for entrenching that elitism..
-
He fits into it by disseminating talks from elitist, closed, shop conferences for as long as he can. The CLA orgies should be considered more like TED Talks than old boys' networking dinners. From what I have seen, the speakers seem to feel that way and the sessions certainly don't fit the sales pitch format so I am left wondering wonder why your arguing for Christmas.
-
That'd be great. I'm not privy to CLA orgies but if you could smuggle out some stuff, I'd be interested in seeing it. I'm looking for a replacement IPC between websocket connected service modules and been experimenting using JSON for that so I'd like to see where your work is heading

Tell me more! JSON-WSP too? SOA is an area which deserves more limelight.

Sure. Go back about 20 years and you would send an email to a guy/gril ( in plain English or whatever language, who you didn't have to pay) and they would incorporate your patch, or idea into the software. You didn't even need the commands. You can still do this with mailing lists today for some projects. I suggested you should be in sales because only a salesman would effervesce that such a backward step would be a positive.

This axiom is usually completely false. IT departments have stringent policies on patches and things like VC++ et al usually require sign off by a competent authority. I expect if you dig deeper there is a whole process before pushing out patches/updates. It is for such policies that Windows XP is still in use in the finance sector and Microsoft are not forcing updates on enterprise users in Windows 10 as they are with the chattel consumers. I know most software suppliers feel they own our hardware (less so NI, but they are getting there) and at liberty to install anything that they deem appropriate for their or their country's business but people like me and Hooovahh are here to dispel that myth.....just sayin'

Implicit vs. Explicit Property Node: Performance Difference?
ShaunR replied to mplynch's topic in LabVIEW General
This is probably something NI could easily do for us just by colour coding. -
I've never gotten the scan from string to work, ever (and I have tried ). I have a fundamental misunderstanding of how it works and if it works how I think it might, then it's of no use to me. I think it is probably misnamed and should be called "Extract Literally From String".
-
You mean everyone "at home" auto upgrades where a bug isn't going to slice someones arm off and software is 10s of dollars not thousands with penalty clauses.
-
Yes. It really is "fire and forget". All the hard work is handled by the infrastructure and you can even offload any maintenance to the IT department who will probably insist on maintaining it fro you You just need a router that can handle multicast (almost all home routers, for example). Talk with your IT department and they will probably just give you an IP address then go and swap some patch leads in their secret cave. Ah. But it is browsers as well as, not instead of . You can do everything with Websockets that you can do with network streams plus browsers and other languages understand it. You can think of it as the general standard for Network Streams rather than NI specific. However, I'm throwing a lot of technologies that are new to you here, so I understand the fallback position to good ol TCPIP.
-
You mean like emailing [a patch] to a user group? You should be in sales
-
Great to hear you are looking into one that works for us poor, long suffering, LabVIEW devs (I'm just going to start a self fulfilling rumour)
-
Wise words hardly ever heeded.

Only to the router which hosts the Multi Cast Group. You put a multi cast router in between the source PC and the "real" network then the "real Newtork" doesn't see any traffic unless there is a listener. In this way with your 4MB.sec you can support 0-Network Bandwidth (Gbit?) streams with no variable impact on the cRIO (network determinism). Ah well. If you are going for a full blown server (which is what you need to dynamically handle multiple simultaneous connections with TCPIP) I'll just throw another into the pot then. How about streaming the audio so they can listen using the HTML5 player in their browsers? (websockets)

Timed loop actual start timestamp gives erroneous value
ShaunR replied to eberaud's topic in LabVIEW General
You must have done that on XP. Wimpdoes Vista and up are ~1ms resolution. -
Not needed for UDP. You just transmit different channels on different ports and let them connect to whichever they want to listen to.

Interesting post. Kudos. That is the required personality type for Linux developers who are the ones that tend to write this stuff. I've got all the various different version control systems. They confuse the hell out of me and I'm never really sure if I have committed to my local or the central repo. Even in light of my ignorance. None really work for LabVIEW (see the part where he talks about blobs). They all get demoted to back up systems and there isn't much point in backing up to your own PC. The only issue I have with SVN is the singular history. That is solved exactly the same way as he describes for distributed - break into smaller repos. If you have repos for each sub module/component/sub project then that also becomes atomic work packages which now work properly if you separate source from binary code. Long story short. not so long. I still use SVN and it looks like I've used it so long it's coming back in fashion again PS. Well worth expanding the superscripts inline

Short answer - streaming to multiple clients with TCPIP (aka network streams) from a cRIO is problematic. If you can, use UDP and let the infrastructure "copy" the data (see the Multicast UDP examples).
