<p>The HN title is quite a strong claim, but it's nowhere to be seen in the repo.<p>It seems to be fully prompt based, so the AI still can say anything it pleases.<p>How well do these complicated prompt systems usually work? My strategy is to stick mostly to just simple prompts with potentially some deterministic tools and vendor harnesses, based on the rationale that these are what the models are trained and evaluated with. And that LLMs still often get tripped up when their context is spammed with too much stuff.</p>

<p>> I really don't know where you got the idea that they had any agency in preventing this short of giving Russia all of their territory and fleeing West.<p>This is at best a conjecture. It's arguable what terms are acceptable and to whom, but Russia has offered and is offering substantially milder terms than taking all of Ukraine. They probably wouldn't even want western Ukraine if offered.</p>

<p>The main effect of the treaty is that personnel mine production and trade has dramatically decreased, thus making it harder for (small) non-signatories to deploy too.<p>International treaties tend to be always somewhat aspirational and are often violated and sparsely enforced. This does not mean they don't have any effect.</p>

<p>That's a bit difficult argument to exhaustively address.<p>Personnel mines has been a topic of considerable public, political and military discussion about personnel mines in Finland for a long time and has been analyzed in depth. Even now, after a significant political mood change at around 2024, the official line (e.g. in the government proposal[1] that led to the withdrawal) is that personnel mines have mostly an auxiliary role in the defence strategy.<p>[1] <a href="https://www.finlex.fi/fi/hallituksen-esitykset/2025/56" rel="nofollow">https://www.finlex.fi/fi/hallituksen-esitykset/2025/56</a></p>

<p>161 countries are still in the Ottawa Treaty, including all European countries except the ones who withdrew. I have hard time seeing how this treaty would have much effect on wartime alliances.<p>But if that's the case, what are "all the force multipliers"? Chemical weapons? Biological weapons? What share of the GDP for defence?</p>

<p>I'm in Finland and I would have forgone this measure. It is not a critical, or even an important, part of the defence strategy.</p>

<p>Whatever the reason, this will increase the likelihood of landmine casualties in the future. And not necessarily (only) in this area, but it weakens the treaty in general.<p>Part of these kinds of treaties is to accept some additional difficulty or expenses in defence for a more widespread benefit. I'm living in Finland and I would have accepted these.</p>

<p>Sadly demand for such heros may increase in the future. Poland, Lithuania, Latvia, Estonia, Ukraine and Finland withdrew from the Ottawa Treaty banning personnel mines. And probably more countries will follow.</p>

<p>Continuous formulations are used with digital computers all the time. Limited precision of floats sometimes causes numerical instability for some algorithms, but usually these are fixable with different (sometimes less efficient) implementations.<p>Discretizing e.g. time or space is perhaps a bigger issue, but the issues are usually well understood and mitigated by e.g. advanced numerical integration schemes, discrete-continuous formulations or just cranking up the discretization resolution.<p>Analytical tools for discrete formulations are usually a lot less developed and don't as easily admit closed-form solutions.</p>

<p>> People are just too lazy to put forth even a minimal effort when they believe that there's no payoff to it.<p>For me just disabling IPv6 has given the biggest payoff. Life is too short to waste time debugging obscure IPv6 problems that still routinely pop up after over 30 years of development.<p>Ever since OpenVPN silently routed IPv6 over clearnet I've just disabled it whenever I can.</p>

<p>Heroin was produced in huge quantities and it was a very popular drug for many ailments, including cough, asthma, insomnia and calming down children. It declined only after the 1912 International Opium Convention. In Finland it was a popular cough suppressant until the 1950s. In e.g. UK it's still used for severe pain.<p>Heroin (diamorphine) as a molecule isn't really substantially more problematic than e.g. oxycodone or fentanyl, which are in widespread medical use. The specific ban of heroin is more a historical contingency.</p>
