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.

Daryll who? >On April 9, 2010 McBride purchased the SCO Mobility intellectual property from The SCO Group for $100,000. Imagine paying 100,000 USD in 2010 for something that was proven to be worth nothing. Even the name "SCO" is so tarnished after what McBride and his cohorts did that it is worth nothing. On a related note, I made contact with Doug Michels, one of the founders of the original Santa Cruz Operations. Doug is a good guy and I worked with him for years during the heady days of the "Common Desktop Environment". In 1997 Doug was on the board of Uniforum and insisted that Linus Torvalds get a lifetime achievement award at the tender age of 28. md On Thu, Feb 11, 2021 at 12:50 PM Tim Keller via WLUG <wlug(a)lists.wlug.org> wrote: > Hey Gang, > > We've got a meeting tonight at 7PM! > > Location: Our usual Jitsu haunt: https://meet.jit.si/WlugMA > > Topic: I think the Itanium thing got beat to death, but we can still talk > about it. > Apparently there's still a pa-risc port of linux kicking around?

Reminder! Virtual Meeting Tonight!! 7PM via Jitsi!

by Tim Keller

Hey Gang, We've got a meeting tonight at 7PM! Location: Our usual Jitsu haunt: https://meet.jit.si/WlugMA Topic: I think the Itanium thing got beat to death, but we can still talk about it. Apparently there's still a pa-risc port of linux kicking around? Now I want to run it as a VM! Daryl McBride (SCO asshole) just fired for Chapter 13 so we can laugh at his expense. I'm sure there'll be some 3d printer talk, some Pi PICO chatter, plus whatever else. Later, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Yes, know it's configured differently. On purpose. I have configured it _not_ to waste time answering stupid questions from random bots. If you want to know the address of isc.org, ask a major name server. My server is for answering questions about _my_ names. It needs to answer queries about keithdiane.us and free-comp-shop.com, for which it is authoritative, which means the major name servers get their info about those names from _here_. I would like to configure it to totally ignore such stupid requests, instead it seems to be answering with the best data it has in its cache. That turns out to be the most verbose yet useless information imaginable---a list of all the root name servers on the internet! -- Keith PS: Don't use my list. It's probably obsolete.

by Chuck Anderson

Correct, Keith's server is not configured to current best security practices. His server has what is called "upward referrals" turned on. https://www.dns-oarc.net/oarc/articles/upward-referrals-considered-harmful I believe what you want at a minimum is: additional-from-cache no; Also, it sounds like you are using your DNS server for two functions: caching for internal clients, and authoritative for your domain name(s). If so you probably should isolate both functions: "If your nameserver is both authoritative and caching, you really should separate the two functions. Caching nameservers are susceptible to poisoning and other types of attacks. You don't necessarily need separate hardware for each. You might need to use separate IP addresses, or possibly configure the authoritative nameserver to use an external address while the caching nameserver uses an internal address."

I hope to make it. I'll have to borrow Diane's laptop. My Linux laptop makes a fine computer, but a bad television It says "Topic: Good question!" So here's my good question: I run a name server (DNS). A few days ago it started getting abut 100 requests/min from many different IP addresses all for isc.org. Why are they asking me? I believe I have it set up so that queries from inside the house are so-called "recurive"--- it searches the internet for an answer, but queries from outside are anwered only with info it already has. I am not sure if that means it only answer queries for which it authoritative, or if it also anwers if it has the data cached. I would like it to just blow off any queries for which it is not authoritative. Tell where to send mail for @keithdiane.us and not even answer otherwise. It is remarkably difficult to get it to put replies into the log file, even if it is logging the queries. Could somebody run the following and tell me the results? dig @66.92.74.188 isc.org (that's my IP address) -- Keith

I don't want to join the endian wars. So I'll comment on something else. Stratus did not support Itanium because they follow rather than lead the market. When a replacement for PA-RISC was considered at Stratus we did look at Itanium. I recall studying the FW then called "EFI" around 2003 when I was in the VOS group. For the in-house VOS OS, Stratus would need compilers for PL/I and C and a modified linker to get to Itanium. Stratus never made this investment. What the VOS group did was to port to x86. Today VOS is still a 32-bit OS that runs on Motorola 68K, i860, PA-RISC and x86. This is unlikely to ever change for VOS as the compiler and linker tech leads have left Stratus. For the other three OS's supported by Stratus, Windows, Linux, VMware ESX, outsiders, not Stratus, would or would not be porting their OS to Itanium. (As was the case for amd64). Since the Stratus value add is to take applications coded to run on commodity HW and make the apps highly reliable by running on Stratus HW, Stratus would not move to Itanium until the customers already were developing to that platform. -- One more comment on a different topic: > >I personally play around with ATTiny85 and ATTiny84 MCUs when I get a >chance. Slowly looking at STM8 and STM32 stuff as well. And of >course the Arduino AVR stuff. > Me too, but somewhat bigger/faster MCUs. I still occasionally code in C, but it is more productive with high level interpreted languages on these chips. Lately I'm very excited about esp8266 and CircuitPython.
