The premise is just false. The parable might be true when comparing, say, lower class vs lower-middle-class, or lower-middle-class to middle class. But the difference between upper class and middle class is not "spending less money." It's a vastly different net worth that comes from inheritance, building / running businesses, investments, etc.

The boots theory focuses on the costs, but the real difference comes from the income & net worth

The language is not a feature!

I'm a C++ programmer, and even I don't care what language the applications I use are written in.

"Fast" is a feature, not that it's in C++

A transformer-based (but not LLM) chess model that plays like a human. The site right now is very rudimentary - no saving games, reviewing games, etc., just playing.

It uses three models: * A move model for what move to make * A clock model for how long to 'think' (inference takes milliseconds, the thinking time is just emulated based on the output of the clock model) * A winner model that predicts the likelihood of each game outcome (white win / black win / draw). If you've seen eval bars when watching chess games online, this isn't quite the same. It's a percentage based outcome, rather than number of centipawns advantage that the usual eval bars use.

Right now it has a model trained on 1700-1800 rating level games from Lichess. You can turn it up and down past that, but I'm working on training models on a wide variety of other rating ranges.

If you're really into computer chess, this is similar to MAIA, but with some extra models and very slightly higher move prediction accuracy compared to the published results of the MAIA-2 paper

Strong base salary plus quarterly cash bonuses depending on firm performance.

We're a digital asset hedge fund with a 7-year track record of delivering outstanding returns for our investors.

We're hiring a data visualization engineer to build C++ / Python / Qt applications for internal use by our researchers. Previous experience in real-time visualization of large data sets a plus. If you know what a DOM ladder is, that's a huge plus.

Runs on a local LLM, because even using GPT3 costs would have added up quickly.

Currently requires CUDA and uses a 10.7B model but if anyone wants to try a smaller one and report results let me know on github and I can give some help.

For instance, you can instruct it to "Hide all tweets, except for tweets about machine learning (ML), artificial intelligence (AI) and large language models (LLMs)."

I've tested it and got good results with a 10B parameter model, but I suspect a high-quality small model like Phi-2 might work almost as well.

It's open source and available at https://github.com/thomasj02/AiFilter

What are the best resources for learning things like GPU architecture, CUDA, Triton, etc?

My goal is to do be able to do something like take a description of Flash Attention and implement it from scratch, or optimize existing CUDA code.

We're thinking about homeschooling him for the remainder of grade school and then re-enrolling him into the traditional school system once he reaches high school. We're concerned however that we may not have the patience or pedagogical experience to effectively teach him.

Does anyone else have experience trying to homeschool? Success / failure stories, or best practices?

Yes, I think it is absolutely 100% fine.

Right now a pain point is trying to set time limits on websites (like youtubekids or lego.com) because although I don't object to them per se, I also don't want him to spend hours browsing the lego website, watching videos, etc.

On iOS devices there are good tools that allow granular level time blocking of websites, apps, etc. Does anyone know of any tools that allow even basic password-protected time blocking on desktop browsers, or a cross-platform (iOS/Linux) time limiter?

> Noncausal mechanisms, including socioeconomic status and reverse causation bias, have been proposed as contributors to the KIHD findings (Kivimaki et al., 2015). Although differences in socioeconomic status may influence sauna access and opportunities for use, the robust dose-dependent associations observed between sauna bathing and sudden cardiac death, coronary artery disease, and cardiovascular events in the KIHD studies are indicative of genuine inverse associations (Laukkanen et al., 2015a). Furthermore, the KIHD studies were conducted in Finland, where sauna use is deeply rooted in the culture, and saunas are readily accessible (Laukkanen et al., 2015a). Similarly, whereas reverse causation bias figures prominently in observational studies and is a valid concern when investigating links between cardiovascular disease and lifestyle, the KIHD findings were adjusted for potential biases, including lifestyle factors such as socioeconomic status, physical activity, and cardiorespiratory fitness (Laukkanen et al., 2015a).

I get one or two cold emails from tech recruiters on LinkedIn every week, often from different recruiters at the same couple of agencies.

How do I choose a good recruiter? What do you look for as red flags or positive signals?

Has there been any formal research on new programming language acquisition? Does anyone have a specific "new language" process that works particularly well for them?
