The issue I have with these arguments is that they assume that just because a certain thing has flaws there must be a better solution. What if predicting long-term effectiveness using a limited amount of time is inherently approximate at be

As someone else mentioned, test suites are a bit of a tough case for JITs. That said, we really don't want to slow down any workloads, and I suspect that something might be going wrong if you are getting a measurable slowdown. Is this

I'm not sure of the bindingness of this page [1], but the FTC says that transactional-vs-promotional is determined by what what a recipient "reasonably interpret[s]" it as, not what the sender says it is. Not that this preven

Ah this is a different version of the problem. There are quite a few listed on the wikipedia page. I believe the version you are talking about is just a simple equivocation.

Every envelope you open will have a higher expected value than the previous one. This is not paradoxical, it is a standard property of probability distributions with infinite means. I believe the problem you are trying to elicit is that you

If I open an envelope with $10 then I know that there is $20 in the other envelope. As soon as you assign a well-formed probability distribution to the money in the envelopes you will find that opening the first envelope is informative.

If you disallow negative values of k then you break the symmetry argument, and you do indeed get quite a bit of information by opening an envelope. I assume you meant to use a exponential base <0.5 so that the mean is finite

Note that the problem requires allowing arbitrarily small amounts of money in the envelopes, otherwise you would know at some point that you have the smallest amount of money possible. So in your formulation, you have to let k be negative a

by kmod 4y ago
If it is truly the case that the second envelope has equal probability of having half or double the amount of money as the first, then you can prove that the probability distribution of money in each envelope is not well-formed (has total m

Bit of context for this: - Cheaper Python frames are enabled by making some semantic changes to the language, mostly by removing some dynamic functionality that no one uses - "Inlined Python function calls" is a bit misleading: Py

I think the interviewing process is an extremely informative view into what it's like to work at that company. The exact steps to take depend on how bad it is / how much you want the job / other context, but I think it's

Cinder does this (invalidation), and both Faster CPython and Pyston use guarding.

I tried to benchmark GraalPython for the talk but the compatibility situation was so poor that I wasn't even close to being able to run any benchmarks.

Python dictionaries now have version counters that track how many times they were modified, so the quick check is to ask "was len not overidden last time and is the number of modifications to the globals the same as it was last time&qu

Personally I think it's valid to consider selection-bias effects in authorship -- in general, things are written by the people who are the most excited about the topic, which leads to there being a bias towards excitement. I don't

I worked on this for my masters thesis! The thesis was for a specific part but the group worked on the problem as a whole, see https://dspace.mit.edu/handle/1721.1/49844 IMO there are two things that make the curr

There has been some effort to quantify "AI scaling laws": ie how much performance increases as we scale up the resources involved. See section 1.2 of https://arxiv.org/pdf/2001.08361.pdf My main takeaway from

This kind of thing scares me about the current state of AI. Language models are trained to produce text that looks like the training data, but if the training data has falsehoods they will happily repeat those falsehoods. I just put the exa

I think these sorts of arguments are not great because they confuse "limiting behavior" with "behavior at the limit". Yes if you are able to construct an infinite-sized MLP it can exactly replicate a given function, and

Shameless plug: Python 3.11 comes out this October and is slated to be 10-20% faster, but Pyston is already available and is 30% faster. We do the things that are listed in this pdf, but also additional things that will probably never make

Yes, definitely. Python is much much more dynamic than Javascript -- the jump in dynamicness of Javascript to Python is about equivalent to Java to Javascript, and similarly requires a different set of techniques. The single example I typic
