WLUG Meeting July 18th 2019 NOTE: Location Change: WPI Campus Center: Morgan Room

by Tim Keller

Hey Everybody! We've got a meeting this Thursday July 18th at 7PM! Location: WPI Campus Center: Morgan Room (main floor hallway to the left of the front desk) Topic: Pi 4 I thought we might talk about the pi 4. I'm going to grab the 1GB version so we'll have a sample device to poke at. I'd really like the 4GB version, but those are a bit hard to find.. I'll have it, plus a pi 3 and an assortment of older pi's as well. As usual snacks and refreshments will be provided and we'll head off for dinner to continue to the conversation. Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Next Meeting moved to July 18th 2019

by Tim Keller

Hey Gang, I'm moving the meeting down a week since I'll be on vacation next week. The meeting will be on July 18th. I'd love to do a comparison of a pi 4 vs. a pi 3, but buying a 4GB pi 4 is a bit challenging... If someone already has one and could bring it, that would be awesome, if not we'll have to think of a different topic. Yeah, I know you can buy a 1GB/2GB pi 4... but really why would you do that. Thanks, Tim. WLUG President -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Dual GPU Laptops Experience?

by Dennis Payne

I bought my last laptop from System 76. It's worked well but I was thinking of upgrading. I run Fedora so I wiped the Ubuntu installed by System 76 and haven't had any problems. However my current laptop only has the Intel graphics. The new Gazelle, which is closest to what I have, includes Intel and Nvidia. Anybody have any experience with that setup with Fedora and Wayland? Does it work out of the box? Do you need to install System 76 tools to switch between the different chips? Does Nvidia with Nouveau driver give better performance over Intel? I'm unlikely to install Nvidia's closed source driver. -- Dennis Payne dulsi(a)identicalsoftware.com https://social.freegamedev.net/channel/dulsi

Reminder: June WLUG meeting TODAY! Topic: Side Channel Attacks.

by Tim Keller

Hey Everybody, We've got a meeting today, Thursday June 13th at 7PM! Location: WPI Campus Center Mid-Century room (rm 331) aka, the usual haunt. After last meeting we ended up having a side conversation regarding the now multiple side channel attacks that the Intel microarchitecture is vulnerable to. I thought it might be a good time to actually deep dive what these are, why they keep happening, why they're likely to continue and what efforts are being put in to try to mitigate them and the effects these migrations have on performance. As usual snacks and refreshments will be supplied and afterwards we'll head off for dinner to continue the conversation!

Hey Kevin, WLUG is an open door meeting. If you'd like to attend, you're more than welcome to show up. As far as this months topic, It might also be worth talking about cpu management engines, since they're also a major source of vulnerabilities, as AMD found out this week. https://www.tomshardware.com/news/psptool-amd-secure-technology-psp-firmwar… Logan On Sat, Jun 8, 2019, 07:34 Kevin via WLUG <wlug(a)lists.wlug.org> wrote: > I have been on the mailing list a while..... > > I would like to come up a meeting this Jun 13. > > Are there any specifing instructions for a first time visitor? > > > On 6/7/19 9:10 AM, Tim Keller via WLUG wrote: > > Hey Everybody, > > We've got a meeting on Thursday June 13th at 7PM! > Location: WPI Campus Center Mid-Century room (rm 331) aka, the usual haunt. > > After last meeting we ended up having a side conversation regarding the > now multiple side channel attacks that the Intel microarchitecture is > vulnerable to. > > I thought it might be a good time to actually deep dive what these are, > why they keep happening, why they're likely to continue and what efforts > are being put in to try to mitigate them and the effects these migrations > have on performance. > > As usual snacks and refreshments will be supplied and afterwards we'll > head off for dinner to continue the conversation. > > Thanks, > Tim. > > -- > I am leery of the allegiances of any politician who refers to their > constituents as "consumers". > > _______________________________________________ > WLUG mailing list -- wlug(a)lists.wlug.org > To unsubscribe send an email to wlug-leave(a)lists.wlug.org > > _______________________________________________ > WLUG mailing list -- wlug(a)lists.wlug.org > To unsubscribe send an email to wlug-leave(a)lists.wlug.org >
