<p>No.<p>With databases there exists a clear boundary, the query planner, which accepts well defined input: the SQL-grammar that separates data (fields, literals) from control (keywords).<p>There is no such boundary within an LLM.<p>There might even be, since LLMs seem to form adhoc-programs, but we have no way of proving or seeing it.</p>

<p>The principal security problem of LLMs is that there is no architectural boundary between data and control paths.<p>But this combination of data and control into a single, flexible data stream is also the defining strength of a LLM, so it can’t be taken away without also taking away the benefits.</p>

<p>> a lot of real world performance comes down to how efficiently you are calling external services (including the database)<p>Apart from that my experience over the last 20 years was that a lot of performance is lost because of memory allocation (in GCed languages like Java or JavaScript). Removing allocation in hot loops really goes a long way and leads to 10 or 100 fold runtime improvements.</p>

<p>I have been alone for quite some time in my life, for various reasons.<p>Here is my advice<p>1. Don’t listen to people telling you that there‘s something wrong with you if you aren’t happy alone and that you need therapy. You probably don‘t.<p>If you aren’t able to survive a single day on your own, then you have an issue, but in general people are social animals and need talking to and touching other people on a regular basis to regulate themselves emotionally. Some don’t, but you don‘t seem to be one of them. (In my experience people who honestly enjoy being alone for weeks at end often got used to this in their childhood, for example by being single children. If you had a noisy, lively house when growing up you will always miss that.)<p>2. That being said it is still nourishing and useful to follow the tips for spending time on your own (cooking for yourself, going into the cinema) now and then. But don‘t expect it to magically fix your yearning for social connections.<p>3. Doing sports and going to the gym often is great advice, because sports generally gives you a more positive mood and a better outlook and it quiets down negative thoughts. But also keep in mind here that it will not replace social interactions and touch.<p>4. So the question remains where you get your social interaction from, and I suggest that you replace the single person you had with a lot of tiny social interactions.<p>None of those is going to fix your solitude on it’s own, but the mixture will enrich your life. If you do all of those things once per week, your mood will improve:<p>- Online dating and chatting with friends (but don’t expect anything to come out of it)<p>- Dancing classes (this is especially great because you get the physical touch component)<p>- Regular coffee/dinner dates (1-2 per week) with a friend, coworker or relative.<p>- Going for a walk and talking to a random stranger<p>- Singing in a choir or similar hobbies<p>- Going to pubquizzes or free to join community walks<p>- Commuting to the office instead of doing home office.<p>5. I won‘t argue against your psychiatrist, but I find that medication is only useful in a minority of cases. Both anti depressants and anti anxiety meds can actually reduce your motivation to go out, by mellowing you into a not-great-not-terrible dreamy state.<p>6. Don‘t start rummaging and contemplating your thoughts when you are lonely. Being lonely makes you weird: <a href="https://arstechnica.com/science/2023/07/lonely-people-see-the-world-differently-according-to-their-brains/" rel="nofollow">https://arstechnica.com/science/2023/07/lonely-people-see-th...</a></p>

<p>I once digged into this database out of curiosity and found incredibly detailed research on many edge cases. Like time zones in Germany being temporarily aligned to Moscow during soviet occupancy after World War Two.<p>One particular commenter stood out to me, so I looked him up because I was interested which kind of people spend so much time correcting timezone information.<p>Turns out he was an astrologer and wanted his astrology-program to work perfectly correct.<p>I find it funny that we have to thank astrology for the correct calculations in our banking software :).</p>

<p>> Almost no one is shopping multiple supermarkets, buying cheaper alternatives, buying in-season veggies and fruit when it’s cheap, waiting for sales to stock up, buying in bulk and freezing, using coupons, meal planning based on the latest supermarket Sunday circular, etc. only a tiny minority of people have been doing so.<p>I don‘t know where this observation comes from, but here in Austria a majority of people in lower income sectors than IT do all of this?</p>
