Once you understand the data model, you understand everything. That doesn't take a lot of time. Does that talk happen to be available on youtube or some equivalent? I'm a git fanboi in spite of its failings. I've been using git since Linus and Larry McVoy divorced (amicably, claims Linus) over where the kernel source repo would reside. That amicable divorce spawned the development of git in the first place (says Linus). I'm no expert on git, but 'git bisect' has allowed me to file countless (for countless = than the number of cc's of vino in my glass) bug reports over the years. I see that all the gentooers who replied to my post have been lingering in this mailing list for years. (You are Old Farts, by my definition.) All gentoo Old Farts are here because we are gentoo addicts and not one of us could abandon gentoo even if we wanted to. Including me. That may help me too. It took me a while to have a sorta understanding of how Gentoo is set up ebuild wise and such and now I feel like I did back in 2003. Having it on youtube or something would be really good. I did find this tho: https://www.youtube.com/watch?v=73I5dRucCds I'll try to watch it later. Don't. You'll waste an inordinate amount of time listening to the drone of someone's uncontrollable verbiage, which contains less that 1% meaningful information. I suspect that 10 minutes should be enough to explain what git is, what github is, how you use them. Unfortunately, any videos I found over a 10 minute youtube search didn't provide me with anything useful to share. :-( -- Regards, Mick signature.asc Description: This is a digitally signed message part.

JTAG interfaces to the hardware is even cooler. Gotta get a giant magnifier for that sort of access work. Glad to have helped. If you get into EXIF data. check out "photogammetry" as 2d still photos can be 'stitched' together to create awesome 3D and 3D+motion models. One of the key usages of HPC. If I can only stay healthy SfM (structure from motion) is my latest addiction It's just very very cool technology. Some folks are building 3D-motion models of the inside of their lab. Cover the wall with monitors and then animate the objects inside, work remotely (like a VR game) or walk into the home_lab and work as normal. Building your own, is where the fun is. Get a UAV pilot's license and a sub 1K drone and well, just let your imagination go wild! gqview -- nice piece of old software. I'll have to check it out.. it's age on sourceforge is a bit to worry about. I'd pack it up and put it in /usr/local/ or at least into a github/gitlab/gogs or wherever you archive codes. Lots of stuff is disappearing now, related to geo-tagging and image processing. I've pretty much settled on [ https://gogs.io ] Surely there are plugins for palemoon that yield up EXIF data? (btw palemoon-28.0.0 is very stable). Here are some random points of interest,should your 2D images lead to 3D and beyond; here's a good intro:: https://www.prusaprinters.org/photogrammetry-3d-scanning-just-phone-camera/ Here is the latest read on mixed reality:: https://software.intel.com/en-us/blogs/2018/06/18/siggraph-2018-the-state-of-photogrammetry-in-real-time-graphics And if intel machines get 'out of control' well, we'll just have to jolt the some electrons with odd_spin:: https://github.com/ptresearch/IntelTXE-PoC All of this on gentoo? Sure, that's why I'm working on Hybrid-heterogeneous HPC gentoo clusters. But I'm AMD_Radeon_arm64 open source centric with my work. I'd be most appreciated if anyone can add more detail, list of FOSS codes, or other related packages and details. hth, James

Security by obscurity, which is what the GRC 'Shields Up' port scan website proposes, offers no security at all. Don't get me wrong, S Gibson has set up a really good marketing enterprise at grc.com and made tons of money by spreading FUD. In the days of MSWindows 98 when ports and shared folders were inadvertently left open to the Internet with no firewalls in-between, port stealth was one desperate measure to increase security. However, the fact a port may not respond to a probe does not mean in any way that the port is not vulnerable to attack. Thankfully, I don't think many of us are using MSWindows 98 directly connected to the Internet these days. ;-) > I'm not going to dream about being as secure as a bank or > something. It's not reasonable to think I could do that. Hmm ... I wouldn't be that sure. Gentoo well configured is pretty secure and does not use RC4 ciphers or allows the connections to be degraded to lower strength ciphers like some banks do. In addition, I hope you have not outsourced responsibility for your own network's security to some underpaid drone in a 3rd world country, as your bank probably has. > I just want > to be reasonably secure given what I can reasonably do.

Hopefully that is enough. OK, we're back into discussions that may have held true back in 1998 Cable modems operated as a node exposing local users connections to each other. You used to be able to connect to a neighbour's MSWindows 98 PC and browse his files. These days cable nodes implement DOCSIS 3.0 or 3.1 spec. which includes encryption between CMTS and modem. In addition, most modern cable modems also offer NAT routing. So the security of consumer LANs is the same with your typical DSL router. > I've been running Linux for over a decade.
