Onno (VK6FLAB)@lemmy.radioto No Stupid Questions@lemmy.world•Should I be worried about "Prompt injection" attacks on my gmail?102·2 days agoI work in ICT. Leaving Gmail is much easier said than done. It has the best spam filtering bar none and integrates with a whole host of other services that I use daily, like the mobile phone I’m writing this on for example, the one that integrates my calendar, tasks, contacts, photos, websites, YouTube channel, spreadsheets and, oh yeah … that other thing … Gmail.
So, if wishing made it so.
What I’d like is a Google Workspace tier that is entirely without AI.
Onno (VK6FLAB)@lemmy.radioto 3DPrinting@lemmy.world•Alternative to PrusaSlicer on Linux/ARM64English5·2 days agoOrca Slicer is open source and as far as I know a fork of Prusa Slicer. I suspect that you can compile from source with whichever version of OpenGL you want … if any.
Disclaimer: I’ve only just started looking at it for a different use-case, but it seems like it will do what I’m suggesting.

Onno (VK6FLAB)@lemmy.radioto Selfhosted@lemmy.world•Do you actually audit open source projects you download?English5·16 days agoI run projects inside Docker on a VM away from important data. It allows me to test and restrict access to specific things of my choosing.
It works well for me.
Onno (VK6FLAB)@lemmy.radioto No Stupid Questions@lemmy.world•Why do people care so much that their friend or family member’s partner is attractive and not just loving?16·16 days agoOh … you’re a dick … thanks for self identifying.
Onno (VK6FLAB)@lemmy.radioto No Stupid Questions@lemmy.world•Why do people care so much that their friend or family member’s partner is attractive and not just loving?16·16 days ago- I’ve been here for almost six decades.
- I don’t know what the topic of “procreation genetics” means outside this thread where I was attempting to answer OP’s question and put those two words in sequence to explain myself.
- I think that life has an imperative to procreate and has done so since it started.
- Life, as we currently know it, appears to revolve around genetics.
- I’m not sure what you’re talking about.
Onno (VK6FLAB)@lemmy.radioto No Stupid Questions@lemmy.world•Why do people care so much that their friend or family member’s partner is attractive and not just loving?1·16 days agoI’m guessing that being gay doesn’t turn off the part that’s looking for a beautiful mate.
Onno (VK6FLAB)@lemmy.radioto No Stupid Questions@lemmy.world•Why do people care so much that their friend or family member’s partner is attractive and not just loving?174·17 days agoI’m pretty sure that it boils down to successful procreation genetics. As in, the more attractive you are the bigger the selection of mates you have access to. It’s been happening for as long as life has existed here.
No doubt this has across history been heavily distorted by culture, art and religion and in more recent times by fashion, marketing, advertising and media.

Onno (VK6FLAB)@lemmy.radioto Programmer Humor@programming.dev•When you accidental format the wrong /dev/sdX6·24 days agoThe SCSI solution requires making sure that you have the right terminator connector because of course there’s more than one standard … ask me how I know … I think the Wikipedia article on SCSI says it best:
As with everything SCSI, there are exceptions.

Their “official” contact details, and that of every society is here:
The Wikipedia page of societies is here:

Onno (VK6FLAB)@lemmy.radioto Amateur Radio@lemmy.radio•Could you use a stationary array of antennas to form an image?English3·1 month agoThat you posted in this community means that I am going to assume that you understand that light and radio are the same thing. This means that anything that can “detect” light is essentially an antenna, for that (range of) frequency(ies). The Charge Coupled Device sensors or CCD sensors are in common use in digital imaging, it’s an integrated circuit that can detect light. Or said differently, a CCD can detect radio waves at light frequencies.
In other words, a CCD chip is an array of antennas, that do what you describe.
I’m not sure what a densly packed array of nanoscopic antennas brings that isn’t already solved with a CCD.
CCD’s are also used outside the visible spectrum in all manner of places.
Onno (VK6FLAB)@lemmy.radioto homeassistant@lemmy.world•Simple light automation questionEnglish7·1 month agoBefore you start consolidating, consider what might happen if the switch is in an unexpected state. For example, someone turned off the heater or pump and you were expecting it to be on.
In other words, you need to consider what a “safe state” is for each thing and how your code, when it fails, reverts to that state. This is an example of “failsafe”.
Note that I said “when it fails”. This is true for all software, even on mission critical systems.

Onno (VK6FLAB)@lemmy.radioto Linux@programming.dev•Malicious Go Modules Deliver Disk-Wiping Linux Malware in Advanced Supply Chain Attack4·1 month agoThere’s a reason why there’s only privileged write access to /dev/sda.
If you run unknown software as root on any computer you get to experience first hand the impact of: “fuck around and find out”.
I can absolutely guarantee that you are not the only person to have spent quality time getting to know the intimate backwaters of a codebase tracking down a bug that you introduced whilst tracking down a bug.
