Fedora 34 updates

by THE HAMMER

I just installed Fedora 34 on a "junk laptop" to play along with. Looked on line and wound up with a couple different answers, and so perhaps they are all correct. My question is when I want to update all the packages in the lap top what is the correct/best command? Also what is the difference between dnf upgrade and dnf upgrade --refresh Thanks Ron

Re: Carbon-neutral living

by Chris Thompson

Great start, thanks Joshua! Definitely agree that moving heat is one of the better items to be considering. There are a good few options for the ground-based systems depending on space available and funds. You hit on some YT channels that I typically look at on renewable/green info. One that I'd add to that pile is "Just Have a Think": https://www.youtube.com/channel/UCRBwLPbXGsI2cJe9W1zfSjQ There's also a couple Tesla fan-boys @ "Now You Know". They do a good job covering some interesting renewable tech outside of Tesla as well, including other new (generally electric) transportation options and more: https://www.youtube.com/channel/UCMFmrcGuFNu_59L0pHcR0OA As an aside, Battery Hookup is great for sourcing used low-cycle count batteries that are ideal for things like DIY power-walls for home solar, if you really want to geek out on storage. They've also got a few (small-scale - i.e. camping-size) solar items still available from the Renogy liquidation sale that started a few days ago: https://batteryhookup.com/ (use a code on checkout - BATTERY or DIY normally work for at least 5%) Regards, Chris On 5/14/21 1:45 PM, joshua.gage.stone--- via WLUG wrote: > Hey everyone! > > Thanks for another night full of discussion covering many interesting > topics! > > I'm interested to learn more about everyone's longterm plans for > carbon-neutral/carbon-negative living!

Carbon-neutral living

by joshua.gage.stone＠gmail.com

Hey everyone! Thanks for another night full of discussion covering many interesting topics! I'm interested to learn more about everyone's longterm plans for carbon-neutral/carbon-negative living! My wife and I have been researching on this topic for some time as we believe there are numerous benefits in reducing energy requirements, and we hope that when it comes time to become home owners we'll be able to start from the ground up with this type of living ingrained in our household! It turns out that there's a *lot* of room for improvement in energy efficiency, and by extension, carbon reduction. While I think transition to green energy is immensely important as a longterm plan, I also think it's important for us to evaluate ways to reduce our carbon footprint as individuals Examples include: - Switching to induction stoves which are more efficient and safer than traditional electric stoves https://www.youtube.com/watch?v=pftcQ6NGPfc - Switching to heat pump dryers for reducing energy usage with the added bonus of eliminating the need for vents https://www.energystar.gov/products/heat_pump_dryer https://www.youtube.com/watch?v=Nh-j0sWBEJA - Switching to heat pump water heaters https://www.energy.gov/energysaver/heat-pump-water-heaters https://www.youtube.com/watch?v=omivdhxdGv0 - Switching to air-source/ground-source heat pumps to replacing gas/oil/electric heating for hot water and heating https://www.energystar.gov/products/heating_cooling/heat_pumps_geothermal https://www.energystar.gov/products/heating_cooling/heat_pumps_air_source https://www.youtube.com/watch?v=7zrx-b2sLUs I think heat pump technology could be very promising for a wide number of applications, as it turns out that the most efficient way to work with heat is to simply *move* it around, rather than generate more heat through gas, oil, etc. With climate change and global warming being an existential threat, the last thing we want to do is add more heat to the problem! A more ambitious longterm goal my wife and I have is that we would like to someday have a house built to Passive House standards, which is said to reduce home heating requirements by up to 90%: https://www.youtube.com/watch?v=secB3R0sIYU https://phmass.org/ https://www.buildwithrise.com/stories/texas-passive-house-weathered-the-202… https://zeroenergy.com/portfolio/all-projects https://zeroenergyproject.org/wp-content/uploads/2018/07/RPA_Scranton_Passi… https://www.phius.org/home-page Something I find especially interesting about Passive Houses is that they're often able to achieve net positive energy production and EV charging with even a modust solar panel installation. This means they can give back to the power grid with fewer panels compared to other houses built to code, reducing the total environmental impact from solar panel manufacturing. Of course, there's a high upfront monetary cost to transitioning to eco-friendly living, but at least there are programs in place to help: https://www.masssave.com/ https://multifamily.fanniemae.com/financing-options/specialty-financing/gre… Hope to hear everyone's thoughts! - Josh

Tim, For what it is worth I got my second Pfizer shot February 27th. On March 11th I flew to Miami, Florida for an IPO of Digital Ocean (a friend of mine is a founder), directly into the middle of maskless College idiots doing spring break (I wore a mask and practiced social distancing as well as getting my first two tests for COVID). Two weeks later I flew to Rio de Janeiro for a month (business meetings and to see my husband for the first time in a year). I feel safe in going to indoor restaurants (I still wear my mask when not actively eating and drinking. I trust in medicine, science and statistics, and I feel like Superman. So I would support in-person meetings for vaccinated people, particularly if masks are used. md On Thu, May 6, 2021 at 10:04 AM Tim Keller via WLUG <wlug(a)lists.wlug.org> wrote: > Hey Gang! > > We've got a meeting on May 13th! > > For topics, there's a whole lot to talk about!

Re: Zeek - from yesterday's meeting

by John Stoffel

Guys, Now that I have zeek up and running... what's the best tool/process for viewing the data? Looking at the hourly emailed logs is sorta interesting, but honestly not a great way to see trends over time. I've looked over the zeek.org website, and there's no real discussion there on how to summarize and get a good high level view of what's going on. Even just a daily report would be better, I think. So what I'm doing is setting up my core switch to mirror all the traffic between the switch and the router, while I also have the zeek box on another port on the switch for management. This seems to be working well so far, it's seeing all my traffic to/from the internet and the various devices connected. Cheers, John

Re: Zeek - from yesterday's meeting

by Jon "maddog" Hall

From time to time I used a USB Ethernet port: https://www.bestbuy.com/site/shop/usb-to-ethernet-adapter Generally they are about 25 USD. You might be able to find them on Ebay or other places for less than that. You might as well get a USB 3.0, since it will work with USB 2.0 ports, but USB 2.0 will not support 1 Gbit/second, whereas USB 3.0 will. On the other hand if the networking flow is not 1 Gbit/second then USB 2.0 might work fine. I have found the Linux support for these generic USB Ethernet devices to be generally good. md On Fri, Apr 9, 2021 at 5:09 PM John Stoffel via WLUG <wlug(a)lists.wlug.org> wrote: > > Guys, > I'm looking into Zeek and unfortunately I don't have a second ethernet > port on my main system, so it's not clear how I'd run a span port off > my main switch to grab traffic. > > What hardware do people recommend for a zeek data collection node?

Zeek - from yesterday's meeting

by John Stoffel

Guys, I'm looking into Zeek and unfortunately I don't have a second ethernet port on my main system, so it's not clear how I'd run a span port off my main switch to grab traffic. What hardware do people recommend for a zeek data collection node? I guess I could spin up my old WRAP board (http://www.pcengines.ch) which I used as my main router for years before I replaced it recently. But it's not super fast. It's got three 1gb ports, and 4gb of RAM with a 1Ghz single core AMD CPU. So it might do the job, esp since I can install Debian Buster on there without too much trouble. Sweet! John

Hey Everybody, This is a reminder that we have a meeting on April 8th, 2021. Same bat time, same bat channel Date: April 8th, 2021 7pm: Jitsi @ https://meet.jit.si/WlugMA Topic: As of yet, there's no topic for the meeting, however, there's a ton to talk about none the less! The PHP git server hack, the OpenSSL vulnerabilities, turns out the spectre mitigations can be mitigated? I'm sure more stuff will come up as well.. As usual drinks and refreshments aren't being provided as this is a virtual meeting.. But soon.. so soon I hope we'll all be able to get together safely. Thanks for being patient and coming to the meetings, I appreciate it. Tim.

Re: WLUG history - Doug Waud's Home Networking slide deck found!

by Doug Mildram

I read the first dozen+ slides ( real good wording/intro I'd say!) ..then ADD-like, surfed later slides and found a minor gem in slide30 so I'll type it back here if I may, just for fun : (Networking) Addressing and Networks (review exam :) What address/addresses represent a network and which a host (assume a netmask of 255.255.255.0) a) 192.168.1.35 b) 192.168.7.12 c) 192.168.3.0 d) 192.168.0.255 e) 192.168.0.0 ANSWER: ( network: c,e ) ( host: a,b ) d) is neither, it is the broadcast address for network e Notice how it is natural to refer to that network by its addr 192.168.0.0 Incidentally, that term "host". It simply means computer. You run into it alot when you are setting up ip addresses. (end of slide 30). ============== dmildram,static> those were the days. Mask? What Mask?

I thought I had been to every WLUG meeting back then. Memories fade. I am trying to remember when I went to Mexico...I am pretty sure I was there several times. At the time I was sure I would remember every detail forever, but now I can't recall what year it was. It might have been 2001. > So I updated the WLUG website's Archive section [1] with the slides: > Home Networking (March 2001) Great job of cyber-archeology! I checked it out. It's 80 slides!! That's not a talk; It's at least four talks. I could not have forgotten all that---must not have been there. It's already proven useful in a way redeems WLUG. After moving ethernet cables around to do jit.sw/WlugMA last Thursday, I discovered I had broken another one of those stupid little plastic latch pins on the end plug. I bought a bag of a dozen at Stark electronics about the time of Doug's talk two decades ago. I am down to just three of them. Stark is long gone; where can I get more? I thought of Google, but I could not remember what the plugs were called. After paging quickly through a few slides, there was the answer! They are called RJ-45 plugs and you can buy them through Amazon. They come in bags of 100, which is excessive, but not too expensive; ($10-15). I suppose I will get a bag. That's more than a liftime supply. In a couple more decades you will be able to pick up about 90 of them _real_ cheap at the estate sale, or free from the dumpster. -- Keith

Linux video edit SW : OpenShot is cool ! and.... AppImages

by Doug Mildram

doug> Pardon my non-meeting-attendance all but 1? month since 2020...anyways, (new fun thing or things I got to learn, below) Mostly this email is a Fun/FYI, but I suspect OpenShot could be popular and maybe some of you use it,etc and maybe even one/some of you are dabbling,etc at video editing. Myself, barely so far. TMI Since a friend (for sister's anniversary) wanted to create a slideshow+music ( MP4, say ) I discovered how easy that is on Linux lately (googling offers ~10 or Top Ten choices of SW). And since I put linux on this friend's desktop, it's a great match and way to teach/learn. (gawd, these life-story-in-pictures quests sure can make a camera-bound picture owner/taker have to cope w their mess of jpegs in cellphone) DRUM ROLL: I only tried one offering for video editing, and scored. .......................chose one that some review(s?) said is most user friendly. It (OpenShot) seems great, for my too-simple needs (slideshow of static pics, adding music/mp3) and can obviously do so much more. Output and input choices have huge lists (eg AVI,MP4 variants,etc for output..... you generate/export to). SO ANOTHER THING i learned doing this is: There's a release/package thing I wasnt aware of ... ....seems a too-easy alternate, in favor of pkgs/release-dependent installs/updates. IT IS CALLED an App Image and it really appears to me to be THIS SIMPLE: a) You download one big file, eg for OpenShot a 130-140mb one-executable file that they name OpenShot-v2.5.1-x86_64.AppImage , you can get from https://www.openshot.org/download/ .....which says......... b) AppImage requires no installation. Just download, make executable, and run. doug> Correct, it doesn't unzip anything, and the one executable "fits all". Wow! I will admit that (on my Mint desktop) the first time I run it (as me/plain-user), the GUI intro/setup dialog/window does ask me Yes/No ? for some question about creating something for?on? the Desktop, and I said YES and I did not get anything added to my ~/Desktop. But who cares? More fun anyways to launch it from a terminal and watch the stdout as you run the GUI. p.s. it DOES save PROJECT (not output/export result, but your per-video project setups) in your linux homedir under ~/.openshot_qt/ ...mine looks like: doug0@host:IN_MY_HOMEDIR:~$ ll .openshot_qt/ drwxrwxr-x 2 doug0 doug0 4096 Feb 27 14:23 transitions drwxrwxr-x 2 doug0 doug0 4096 Feb 27 14:23 profiles drwxrwxr-x 2 doug0 doug0 4096 Feb 27 14:23 preview-cache drwxrwxr-x 2 doug0 doug0 4096 Feb 27 14:23 presets drwxrwxr-x 2 doug0 doug0 4096 Feb 27 14:23 assets drwxrwxr-x 2 doug0 doug0 4096 Feb 27 15:17 cache -rw-rw-r-- 1 doug0 doug0 1453 Feb 27 15:57 libopenshot.log drwxrwxr-x 2 doug0 doug0 4096 Feb 27 15:57 title drwxrwxr-x 2 doug0 doug0 4096 Feb 27 15:57 thumbnail drwxrwxr-x 2 doug0 doug0 4096 Feb 27 15:57 blender drwxr-xr-x 30 doug0 doug0 4096 Feb 28 10:15 .. drwxrwxr-x 2 doug0 doug0 4096 Feb 28 10:39 recovery drwxrwxr-x 12 doug0 doug0 4096 Feb 28 10:43 . -rw-rw-r-- 1 doug0 doug0 17352 Feb 28 10:43 openshot.settings -rw-rw-r-- 1 doug0 doug0 1774732 Feb 28 10:43 openshot-qt.log Around 4mb of setup for (so far my only) 66mb MP4 mini-video of PICS w/ 6min of music, the MP4 I exported elsewhere.
