I have a lot of reading to do, but already I learned from wikipedia that >> In early November 2011, Adobe announced that it would discontinue >> development of Flash >> >> https://en.wikipedia.org/wiki/HTML5#%22Thoughts_on_Flash%22 I noticed that it seemed to be going away, but thought it was just web site developers getting smarter: "Hey Joe, Why do we make the customers download flash before we tell them about our product?" It's more official than that. >> What exactly does Zoom or jit.si do then? > > It starts up a WebRTC session over HTTPS to the jit.si server using > your microphone and camera to send your video/audio, As I said, I have never (knowingly) used the camera or microphone on this computer, nor even the speaker/headphones. But I have a few questions: (1) Did you guys see me? I tried to join WLUG meeting last Thu. I never got sound, but I saw some people I recognized, and a picture of myself. I was the guy with the big head. It actually looked bigger than it is, partly because of the firmware in the standard laptop camera which uses AI to zoom in and magnify any slight hint of receding hair, and partly because I was leaning back in a comfy chair with the "Lap"top on my chest. (2) Is the URL https://meet.jit.si/WlugMA still active? Does it work with Microsoft Windows? I am thinking that I could test it out by connecting to WlugMA with my Linux computer while Diane connects with her MS computer. Then we could debug by shouting across the living room. After I quit the WLUG meeting, a poked some menu buttons I had not before and discovered Multimedia ==> PulseAudio Volume Control. By turning that up, I can reliably get sound while playing a *.mp4 with vlc. I tried listening to radio stations (wicn, wbur, wgbh) and it mostly didn't work, but once or twice it did work. I really have no idea why it is sometime but not always. I did notice that when I click (what I take to be) the button to listen to streaming radio over internet it starts looking up all kinds of things I did not ask for (facebook, twitter, chartbeat). I'm wondering if I might have a DNS (named) problem. I have never set up DHCP here, I just assign a static IP address each time I get a new computer. That does not happen often enough to be worth automation. (3) Does HTML5 require DHCP to redirect or forward the data stream? (4) Is there a standard codec or is that something that must be installed to match the whim of the website? -- Keith (Wright) aka Egghead

So there's the issue! If we want to have a productive conversation, then maybe we need to be willing to share our thoughts. Now maybe we limit who can "be in the room" to just those we like. Or just limit people who can write to those we like. But sharing the conversation isn't a terrible thing. > I used to run a smtp mail server on a computer in my basement with a > DSL connection and static IP address. They broke that.

>>>>> "Frank" == Frank Sweetser via WLUG <wlug(a)lists.wlug.org> writes: > The 22nd would work for me. Sounds like the 22nd is the "good enough" date for people. Now for a topic! Can we get a talk on the web browser being developed for the new non-linux system? I totally am blanking on the name(s) right now, but we've mentioned it at the past few meetings. I'll try to bring my new tiny little desktop. The only gotcha is that it depends on my home NFS server for NFS home directories and LDAP for authentication. Which leads to another topic... keeping home directories in sync when you have laptops, home servers, remote systems, etc. How do people keep their setups consistent? I came from an era of Xterms and DEC workstations where all home and tool directories were on NFS servers, and the systems were very light on anything but enough to boot the OS. This way people could sit down at any system, login and their environment was just there. Now with everyone having laptops, I think most colleges have gone away from big computer labs any more. But keeping your files safe is tough. iCloud, OneDrive, rsync, etc have helped, but I'm not sure what the real answer is here. This could be an interesting topic! John

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi All, I forgot to mention that you should print out your fingerprint and bring it to the meeting, to make sure that the one I have on file for you is the correct one. If you aren't able to pre-register, print out 15 copies or so to hand out to people at the meeting. You can get the fingerprint by typing gpg --list-secret-keys | grep ^sec For me, this is 146797fa. Yours will be different. gpg --fingerprint KEYID I'm looking forward to seeing everybody there. We'll have a short talk on the how and why of PGP, then we'll adjourn to Tech Pizza for dinner.

If anyone is interested in a talk on SSDs, chime in. I can present my experiences with these devices. I've evaluated the performance of several vendors' products, ranging from the poor to the exemplary. I can talk about the modifications made in the block layer to accommodate for these devices, and the current implementation of the block discard support (which maps to ATA TRIM, which is important for device lognevity and performance) and how that is wired up to file systems such as ext4.

Maybe at the time we do a Binary Gentoo install and then go into detail about how to emerge and build the apps at a later date. That might actually get me to use Gentoo again.
