Wacom One with Pressure Sensitivity
by Dennis Payne June 11, 2023

June 11, 2023

I bought a used Wacom One a while ago. It is a drawing tablet (not a standalone tablet as it needs to hook up to a computer). It has an display that you can use the stylus on. You can find some examples of my bad art on mastodon: https://cdn.masto.host/mastodongamedevplace/media_attachments/files/110/413… https://cdn.masto.host/mastodongamedevplace/media_attachments/files/110/469… Recently I finally determined how to turn on the pressure sensitivity in gimp. If you go to Edit->Input Devices, you can enable "xwayland- tablet stylus". (Obviously it probably has a different name if you aren't using wayland.) Once enabled the "Dynamics" setting in Tool Options takes effect. You can choose from a large variety of options. For example, "Basic Dynamics" makes pressure affect opacity and velocity affect size. I've been using "Pressure Size" which simply makes pressure affect the size of the pencil (or other tool). It probably hard to tell from this scaled down image but the lines for the eyebrows have a different thickness from the larger outer lines. I used to have to edit the tool settings to do that so this is nicer. I'm sure a trained artist could produce better output. https://cdn.masto.host/mastodongamedevplace/media_attachments/files/110/510… -- Dennis Payne dulsi(a)identicalsoftware.com https://mastodon.gamedev.place/@dulsi

Hey Gang! We've got a meeting tonight! Time: 7PM Date: June 8th, 2023 !!LOCATION CHANGE!! WE will be meeting in the Morgan student center.

Virtual location: https://meet.jit.si/WlugMA Cara Salter is going to show off her flipper zero. If you don't know what the flipper zero is, you're in for a treat. You can check it out here: https://flipperzero.one/ As they call it, it's a multitool for geeks. As usual, I'll have snacks and refreshments and afterwards we'll head off for dinner.

Shippy 1984
by Dennis Payne April 29, 2023

April 29, 2023

I was playing around with Shippy 1984. It is a Space Invaders/Galaxian style game. It is available on Fedora. It's pretty ugly. I decided to play around with a graphics update. Not all of the changes are in git yet. Some refinement is still needed. https://youtu.be/ZAzFP90lgW0 -- Dennis Payne dulsi(a)identicalsoftware.com https://mastodon.gamedev.place/@dulsi

solar/energy monitoring
by Chuck Anderson April 28, 2023

April 28, 2023

I use IoTaWatt (http://iotawatt.com/) for solar/energy monitoring at home. It works with a standard web browser (no app required) and doesn't require any kind of Internet/cloud connection (but can use one if desired). It will keep years of data internally on the SD card and you can make pretty graphs from your phone/laptop/whatever web browser, or you can download the data and do whatever you want with it. It is an open source software/open hardware design by a guy in New Hampshire. It is manufactured in the US, and it is ETL certified. ("The hardware is professionally manufactured in an ISO9001 contract facility in New Hampshire, USA. The base units are ETL safety certified to UL standards") See pics of my setup here: http://www.wlug.org/files/iotawatt/ $314.30 gets you a US 120V bundle with split-core CTs for 14 circuits (2 mains + 12 branch circuits), 9V AC reference transformer, and USB power supply. The split-core/clamp-on CTs are easy to install, just open them up, place them around the wire, and close them. If you use non-split-core CTs (not included in the bundle above), you need to to disconnect the hot lines from each circuit breaker to slip on the CT, then reattach to the breaker.

WLUG Meeting tonight.. maybe?
by Tim Keller April 20, 2023

April 20, 2023

Hey Everybody, The last couple of weeks have been challenging at best. If people want to have the meeting tonight that's great, I'll be unable to make it (quite likely). My Dad had heart surgery yesterday at MGH so there things I need to do. Option #1: You guys just have the meeting without me. Option #2: We push the meeting out another week. Let me know what you guys want to do. Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Okay LÖVE is really cool.
by Tim Keller March 20, 2023

March 20, 2023

Per the post that Dennis made about his porting of Lady Bug using the LÖVE framework, I started looking at it. It's pretty damn cool and it looks like the barrier to entry to making simple games, etc. is really really low. I think it might be worth a talk.

Lady Beetle
by Dennis Payne March 19, 2023

March 19, 2023

I discovered a Love2D remake of Lady Bug. I've never played the arcade game but it looked interesting. It is a maze chase game like Pac-Man but you have these turntiles through out the maze that you can move to alter the maze. The remake was well done but used sprites taken from the arcade game. I replaced all the graphics with new creations. I also modified the game to support two player simultaneous. I wrote up an Open Game Source article about the changes. http://identicalsoftware.com/games/ladybeetle -- Dennis Payne dulsi(a)identicalsoftware.com https://mastodon.gamedev.place/@dulsi

We've got a meeting tonight! Time: 7PM Date: March 16th, 2023 Location: WPI Student Center Chair's Room 129. Address: 100 Institute Road, Worcester MA. Virtual Location: https://meet.jit.si/WlugMA Topic: Ventoy, docker stuff, printers, pi compute stuff, etc. I thought I'd show off Ventoy which is a multiboot usb that lets you run a whole pile of different distros. It's become yet another tool in my pocket when dealing with weird stuff. We can definitely talk about printers.. I've been deploying lots of Ubuntu 22.04 machines and I've had to delve into the fun that is cups.. I can definitely get on the HP hate bandwagon.. There's some scuttlebutt that Docker is talking about purging all the OSS images of users who don't pony up subscription money.. I'm sure we'll dive off into lots of topics as well. Pi compute boards, personal k8s clusters, etc. As usual snacks and refreshments will be provided and we'll do dinner afterwards and continue the conversation. Hope to see you there!

Re-Roll RHEL isos to skip the 60sec countdown and media check
by Dan Davis March 6, 2023

March 6, 2023

Good Afternoon, I'm trying to re-roll a RHEL9 iso to remove the media check and 60s timeout that occurs because rd.live.check is baked into the kernel command line and grub menu. I'd like to use the result with an unattended install. I start by loop mounting the OEM iso image and extracting the contents to a working dir. In the working directory, I've attempted to edit EFI/BOOT/grub.cfg an isolinux/grub.cfg before rerolling the disk with: mkisofs -o output.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table workingdir But after editing either or both, I'm still presented with the 60s default timeout and the media check (rd.live.check) in the kernel commandline. Is there something akin to grub2-mkisofs that I need to do for my changes to the grub.cfg for this iso prior to my re-rolling it? Thank you, Dan

Broken Laptop Screen

March 1, 2023

I have a friend that told me he has kept his laptop stored away because the screen is broken. I do not know if the screen is crack or not operating. I have a monitor from a desktop pc. If I give him the monitor to use with his laptop is there any kind of electrical safety issue? I presume the laptop is windows, and hints on how or if I should tweak the settings? Ron

Tomorrow's meeting is going to be Virtual
by Tim Keller Feb. 22, 2023

Feb. 22, 2023

Hey Everybody, Last week it was the career fair, this week the trustees have reserved everything.. However, the weather looks like it's going to be a mess. Our meeting for Feb. is going to be virtual. I'd rather keep everybody safe they try to find someplace we can all fit. We'll be at our usual virtual haunt: https://meet.jit.si/WlugMA starting at 7PM. The plan is to talk about containerized distributions, though knowing how our virtual meetings go it'll be a hilarious raucous affair. I hope to see you all online and in March we'll *actually* have a physical meeting! Later, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".
