<p>you know that people really go there to dance and enjoy the music?<p>A friend of mine is a professional (modern) dancer, so has as much credentials as you can, and she enjoys dancing in berlins nightlife. She finds the space for expression and creativity in her movement, in tune with the music. Of course, the is not much physical space, which is how the dance-movements evolved as they have (e.g you never spin and you feet never really leave the space they are on). But this is part of the culture, and not a problem. If you can't find it then that's your problem, but doesn't mean that other's can not freely express themselves there.<p>There's more dance-events. Not sure where you are, but you can usually go to a bachata night as it's quite trendy now, northern soul is also getting some revivial. There's also more disco-oriented events usually at various LGBTQ+-parties, I think especially italo-disco is a lot of fun. You can just go out and dance. Lindy Hop also has a solid community around the world.</p>

<p>I am not sure why...you want the LLM to solve problems not come up with answers itself. It's allowed to use tools, precisely because it tends to make stuff up. In general, only if you're benchmarking LLMs you care about whether the LLM itself provided the answer or it used a tool. If you ask it to convert the notation of sheet music it might use a tool, and it's probably the right decision.</p>

<p>people always cheer up stats like that americans are drinking less, but I think what's overlooked is that young adults also socialising less. Turns out, they also have less sex, less relationships, are less extroverted and play more computer-games. I guess they also date less. I am not sure whether that's a win.<p>Btw, from my personal experience in europe, I actually don't see a significant rise in sober adults when going out. Combined with the rise of loneliness (from 12h per week of socialising in 2010 to just 5h!) I think its not because they found a fun sober alternative, I think its because they don't see anyone anymore. Or the other way around: Do the share of young adults, who socialize as much as previous generations, also drink significantly less, date less, have less sex? How do these stats behave when controlled for the amount of socialising one does?</p>

<p>Purely anecdotal, but I was recently reflecting at the current trend of people posting really extensive morning routines. Waking up, meditation, yoga, gym, shower, eating breakfast, meal-prepping,....having a whole day before your day starts. While they should impress you with their healthiness and discipline, I just thought how utterly lonely and sterile most of them look like. And you're completely done after work if this is your morning, you can just go to bed and repeat the same the next day. I found it quite sad, actually.</p>

<p>I really enjoyed how they did it in Tübingen, where I did my masters. You usually had to achieve a certain score on the homework (usually 50-75% of the overall points) in order to be qualified to take the exam. Additionally, if you did really well you got a few bonus points on the exam (something around 80/90%+). This incentivised you to take the homework seriously, especially if you want to get the bonus points. But you still have the written exam at the end as the "controlled environment" and something you have to prepare for, so you can not just listen to the slides once and then forget it after doing the single exercise</p>

<p>I didn't enjoy the city of arts and sciences tbh, it felt disconnected, artificial, maybe almost totalitarian in its will to show off. I also thought that, if you look past the immediate effect, it just didn't feel that good looking. A bit similar to how I often feel about Zaha Hadids work.<p>In comparison, in the barbican I felt like I could sit there for hours and enjoy the architecture. It has so many interesting details and aesthetically pleasing corners.</p>

<p>I am having trouble understanding the document. Where is it stated? I can not exactly follow your argument. I am not sure why being accountable to the people necessitates having not any job protection?<p>I would have expected this to be codified (What is accountability for a federal employee). I mean regulatory bodies should also be accountable but also shielded from political influence, right?</p>

<p>ah ok, thanks for the clarification! But there shouldn't be too many probationary employees, right?<p>So what's administrate leave exactly? Just relieved from your responsibilities? I guess you still get paid.</p>

<p>As someone from europe, I am baffled by the ability to just fire everyone on the spot. Are there no job-protections for federal employees? This makes agencies really dependent on the political climate, right? Can he really just fire everyone? Isn't there even a 3 months notice or something?<p>A separate, connected thought is that I wonder why you would choose being a federal employee then. Here, the government promises job security but it usually means less pay and slower processes compared to industry. If you don't have job security, is then the government forced to be more competitive with industry positions in pay/processes?</p>

<p>it boggles my mind that a place like new york doesn't have the money to just do that. Raising the speed limit gets more important the longer you travel and connects distant parts your city better. It's a recent trend to build high-speed lines to complement an existing, dense subway network (e.g. Paris goes up to 75 mph).<p>I mean when were these built, a 100 years ago? Surely there's room for improvement.</p>

<p>ah no, what i meant that I see these really low-quality, disregarding patches. It seems like, if for example there's some cobblestone-like road, they are not really required to redo it using the cobblestones but can just patch it up? Also some tar just seems way worse quality in these patches, very quickly disintegrating.</p>

<p>interesting. I noticed something similar in the UK but not in Germany. Maybe some simple change in the way these utility repairs are regulated is to blame?<p>While interstates are nice, cities are where people live, so the quality of urban roads matters and is maybe the reason for the perception of US roads?</p>

<p>well, but machine learning is the major reason we use GPUs in the datacenter (not talking about consumer GPUs here). The others are edge-cases for data-centre applications! Apple is uniquely positioned exactly because it is already solved due to a significant part of the ML-engineers using MacBooks to develop locally.<p>The code to run these things on apples GPUs exist and is used every day! I don't know anyone using AMD GPUs, but pretty often its nvidia on the cluster and Apple on the laptop. So if nvidia is making these juicy profits, i think apple could seriously think about moving to the cluster if it wants to.</p>

<p>its possible. Just look at Apples GPU, its mostly supported by torch, what's left are mostly edge-cases. Apple should make a datacenter GPU :D that would be insanely funny. It's actually somewhat well positioned as, due to the MacBooks, the support is already there. I assume here that most things translate to linux, as I don't think you can sell MacOS in the cloud :D<p>I know a lot developing on apples silicon and just pushing it to clusters for bigger runs. So why not run it on an apple GPU there?</p>

<p>I am no frontend-guy, so I don't understand why in the age of node.js web-servers this ditchonomy exists between server-side and client side (SPA). Can't you initialise/pre-render most of your your stuff on the server, serialise it and push it through the client, which then acts as an SPA already initialised and then updates itself on its own. After all, both are JS? Why is the decision not more flexible where to run code, depending on latency, compute intensity etc. Maybe someone can enlighten me, as this is often left out, probably because it is obvious to someone working with these technologies.</p>
