<p>It doesn't seem the case; the study was made purely on behavioral conditioning. And mosquitoes don't live very long, so it's unlikely they'd learn this in practice, outside of a very controlled environment.<p>But there's a natural selective pressure, and it's plausible that mosquitoes would eventually evolve their sensors to become attracted to DEET, over multiple generations. And with each generation lasting only 20-30 days and a single female mosquito laying 300-500 eggs in total, they can evolve orders of magnitude faster than us.</p>

<p>It's really unfortunate that FPGA development is still stuck in the 90s. The incentives between IP owners and hobbyists are so misaligned that I don't see the possibility of this ever improving.<p>The market is full of dark patterns, and vendors like AMD/Xilinx can pull shitty moves like what OP highlighted, knowing there is no decent alternative (Altera is another disaster). Lattice had the opportunity to fully embrace opensource toolchain and try to disrupt from the bottom, but they seem stuck in the middle, not wanting to commit one way or another.<p>I'm grateful to SymbiFlow, and IceStorm and others, even though they obviously lack support for proprietary hardware features.</p>

<p>This is fantastic news. Just a few days ago I mentioned [1] the Obsidian Community Plugins model was broken and needed an overhaul. This is a step in the right direction.<p>If I may, two suggestions:<p>1) Allow the user to filter for plugins based on the desired level of strictness (manually reviewed, safety rating, etc).<p>2) The Disclosures seems a bit too lenient. For example, the popular Templater plugin [2] gets a 92 rating, with Excellent Health and Satisfactory review. But the disclosures are pretty concerning: dynamic code execution, network calls, wasm blobs, malware scan not available, etc.<p>I know it's tricky to boil this down to a single numerical score that works for everyone, but I think the bar needs to be higher than this. And Plugin developers should be held to a higher standard (e.g. don't use eval()) or at least thoroughly document <i>why</i> you need it.<p>[1] <a href="https://news.ycombinator.com/item?id=48089793">https://news.ycombinator.com/item?id=48089793</a><p>[2] <a href="https://community.obsidian.md/plugins/templater-obsidian" rel="nofollow">https://community.obsidian.md/plugins/templater-obsidian</a></p>

<p>Yes, <i>in this specific case</i>.<p>Obsidian Plugins are still incredibly vulnerable. A compromised plugin will essentially take over your machine. There's no sandboxing of any kind. It's even more insecure than browser extensions (that could steal your auth tokens, but at least don't have unfettered access to your filesystem).<p>This is really unfortunate. I love Obsidian and am a paid subscriber for many years, but the community plugins needs a security overhaul asap, before someone gets hurt.</p>

<p>Not sure why you were downvoted. From the last paragraph:<p>"<i>I spent a total of 35 days here. The first arrest was 3 days of processing, the initial 10 days followed by the 10 days extension for a total of 23 days before my case was dropped. But the same time my case was dropped my accusers found a another reason to issue a second arrest keeping me there for an additional 12 days!<p>Both cases were ultimately dropped and the second arrest was essentially tied to the first and shouldn’t have even been possible.</i>"</p>

<p>The answer is in your question:<p>"<i>...through a vulnerable WordPress plugin, a web shell, weak SSH credentials, or a compromised container</i>"<p>DirtyFrag alone doesn't help an attacker; they need to get in first. But the blast radius is much wider now.
