Oh man, this reminds me of my "party trick" back in the day of saying I could tell what OS a computer was running by listening to the HDD seeking. The good old days

It was a bluesky thread I've since lost (lame I know). This article summarizes the issues well: https://residualinsights.com/all-hype-no-bite-your-brain-on-...

Comes down to: - Self selection bias - Trial design - Dubious intepretations of neural connectivity

It is worth noting that this study was tbh pretty poorly performed from a psychology/neuroscience perspective and the neuro community was kind of roasting their results as uninterpretable.

Their trial design and interpretation of results is not properly done (i.e. they are making unfair comparison of LLM users to non-LLM users), so they can't really make the kind of claims they are making.

This would not stand up to peer review in it's current form.

I'm also saying this as someone who generally does believe these declines exist, but this is not the evidence it claims to be.

Nice work! Would totally have used this when I was freelancing. Honestly love the serif'd fonts, would love to see everything serif'd tbh.

Also back when I had to do these (I used Wave) having a notes section was very useful to include a few things (i.e. I used to include conversion rates). Would probably be pretty easy.

Again please read my post carefully. There is a valid critique of overhead rates, but simply doing it suddenly in this manner has little added economic benefit in the long run, while ruining lives and creating waste/chaos in the short run.

You can make a strong argument these institutions require reform, but such reform should be done not overnight, and not through such broad strokes.

1. Why should the public believe that they can fix it. Perhaps they can't, that's not entirely my point. My point is that if the government firmly believes that a change is necessary there are _simple_ ways of acheiving such a change without causing such chaos, waste, and hardship. Perhaps a phased in approach, or other mechanisms. Overnight shock therapy offers very little economic benefits while having very harsh personal and insitutional cost.

2. What is illegal about the change. The NIH overhead rate is actually negotiated directly between the institution and the NIH, following a process put into law. This is why a federal judge has blocked this order [1]. I'm far from a lawyer, but my read of this is that this is a change that would need to come through congress or a re-negotiation of the rates through the mandated process.

The entire academic industry is in turmoil, the uncertainty on how bad things could get is probably the worst of it as Universities are having to plan for some pretty extreme outcomes even if unlikely.

For those who are questioning the validity of a 59% (or higher for some other institutions) overhead rate, your concerns are worth hearing and a review could be necessary, but oh my please not like this. This was an overnight (likely illegal!) change made with no warning and no consultation.

If the government decided that a cap was necessary it should be phased in to allow for insitutions to adjust the operational budgets gradually rather than this shock therapy that destroys lives and WASTES research money (as labs are potentially unable to staff their ongoing projects). A phased in approach would have nearly the same long-term budget implications.

Are there too many admin staff? Likely? Is this the right way to address that? Absolutely not.

For those who are unfamiliar with how career progress works in Academia, it is so competitive that even a year or two "break" in your career likely means you are forever unable to get a job. If you're on year 12 of an academic career, attempting to get your first job after your second (probably underpaid) postdoc and suddenly there are no jobs, you can't just wait it out. You are probably just done, and out of the market forever as you will lose your connections and have a gap in your CV which in this market is enough to disqualify you.

There is also a good case to be made that the prices being bandied around are actually much too high [1]

TL;DR is three major factors:

1. The agencies that are doing the estimates are _very_ bad at exponential development curves (cough cough IEA estimating solar [2])

2. Unfortunately much of the developing world's economy is not growing as fast as we previously thought it would (similar thing happening with birthrates)

3. Many costs are absolute and _not_ marginal, which is just wrong IMO. We are going to need the energy either way, we should be talking about the "green premium" (as far as it exists), not how much it'll cost to generate XX TWH of energy

Quite a fun paper, but very difficult to draw conclusions from. Their headline finding is that they created a map between resting state and "watching a movie".

This is, for better or worse, the kind of research you can only do at institutions which have free fMRI scanning (MIT, Princeton, Harvard, etc.). No behavioural links, only very detailed activation maps that we can't really draw conclusions from. A missed opportunity IMO to spend these kinds of scanning resource on some kind of more narrowly focussed task with some behavioural outcome they can link to brain data.

To me the issue with AI generated code, and what is different than prior innovations in software development, is that it is the the wrong abstraction (or one could argue not even an abstraction anymore).

Most of SWE (and much of engineering in general) is built on abstractions -- I use a Numpy to do math for me, React to build a UI, or Moment to do date operations. All of these libraries offer abstractions that give me high leverage on a problem in a reliable way.

The issue with the current state of AI tools for code generation is that they don't offer a reliable abstraction, instead the abstraction is the prompt/context, and the reliability can vary quite a bit.

I would feel like one hand it tied behind my back without LLM tools (I use both co-pilot and Gemini daily), however the amount of code I allow these tools to write _for_ me is quite limited. I use these tools to automate small snippets (co-pilot) or help me ideate (Gemini). I wouldn't trust them to write more than a contained function as I don't trust that it'll do what I intend.

So while I think these tools are amazing for increasing productivity, I'm still skeptical of using them at scale to write reliable software, and I'm not sure if the path we are on with them is the right one to get there.

Seeing as you're here, the reason the price is too high for us is that "SCALE" plan is too much for us and the "PRODUCTION" plan is too little. I'd happily pay $200/month for two servers, but can't justify $400/month for two (we only have two right now).

My wife studys people for living (experimental cognitive psychologist), the quality of MTurk is laughable, if that's our standard for higher level cognition then the bar is low. You'll see the most basic "attention check" questions ("answer option C if you read the question") be failed routinely, honestly at this point I think GPT4 would to a better job than most MTurkers at these tasks...

She has found that prolific is substantially better (you have to pay more for it as well), however that may only be because it's a higher cost/newer platform.

I had no idea what was going on under the hood but used PGAnalyze for about 6 months after launching a new product. It was excellent at suggesting indexes and monitoring unused ones.

However, after a few months the ROI crept down until it wasn't worth it anymore (access patterns stabilized). I'm tempted to bring it back once and a while but the price tag keeps me from having it always on.

My favorite thing about this report is on energy modelers (section 2.5). They show the (now famous) graph where large institutions (like the IEA) regularly predict that solar will start to have linear growth rather than exponential due to constraints in our energy system. This is despite every previous forecast that did this being wrong, with the number of new solar installations growing exponetially YoY instead.

What is interesting is that despite these constant misses, the IEA is constantly used as the definitive source for energy modeling across the world.

This along with pydantic [0] means that 2/3 of my favorite python open source projects are now commercially backed. I wonder how long FastAPI will last?

As an aside, what is the issue with versioning these days? Ruff and FastAPI both have massive user bases and a reliable codebase, but haven't released v1.0.0! Ruff hasn't even got as far as v0.1.0.

I should have been more nuanced I suppose. There is a time and place for these kinds of image "enhancements", they just don't belong in ESRI's scientific GIS platform. Folks don't view these images for pleasure (or at least very few do), they are typically used to analyze the satellite data or georeference other imagery.

Deep learning image enhancement is totally appropriate in your smartphone, as there the goal is not accuracy but perceived quality. Doing this to satellite imagery where the primary consumer cares about accuracy is what I call "reckless"

This whole concept is so reckless in realms where the image content actually matters and people keep doing it anyways. You cannot CREATE information. You can infer it in certain situations, but if you infer the information and then analyze it you are setting yourself up to make mistakes by overextrapolating a bias/trend in your data to images where you have no idea if that inference is valid.

This was a big thing in the medical imaging community (where I did my stint as a CV researcher), folks were hallucinating microscope images and CT scans with no information theory justification as to why it worked.

Super resolution IS possible, but it must be done by synthesizing new pieces of information, not by inferring based on what other similar looking objects looked like. A cool technique by my former advisor does this with microscopes [1].

Deep learning has a place here, just not as a "lets create information" step, but as a way to learn how to synthesize additional information about images from more sources (i.e. more similar to how Google does Night Sight [2]).

Edit: if you want to see (an attempt) at using deep learning in this field you can checkout one of my papers [3].

[1] https://en.wikipedia.org/wiki/Fourier_ptychography [2]: http://graphics.stanford.edu/papers/night-sight-sigasia19/ni... [3]: https://openaccess.thecvf.com/content/ICCV2021/html/Cooke_Ph...

While I agree that these theory based papers are useful, and are often the precursor to experiments, I believe the general understanding of "study has found X" in pop culture is that there is "hard evidence" of the finding being tauted. Theories are risky to place too much credence in without being steeped in the field yourself (is this a theory that most people in the field agree with, or is the one suggesting it an outlier?).

As usual science communication is never done as well as we could all hope, but I personally like this "hierarchy of evidence" approach in understanding if something is ready to be consumed by the general public, rather than requiring further discussion with the scientific community.

Things that look "good" aren't necessarily ideal for coding. My favorite "bad looking" but very functional theme is the IntelliJ IDEA high contrast theme [0]. Everyone who looks at my screen says it's ugly, but I've yet to find one that is as good for improving readability/

I love the idea, and would consider paying for this after a nice trial period. I love my kindle and it has radically changed how much I read, I used to read maybe 2-3 books a year, now it's more like 2-3 books a month. I find the E-ink screen and "low techness" of it the most appealing. I'm really looking forward to using this for things other than books.

Less doing well because of the downturn, more doing well despite of it, but many players in climate tech are doing really really well lately (for example [1]). Longer term, with IRA [2] now law, the industry is poised to continue to grow faster and faster.

This bill has a ton of what looks like awesome elements inside it, I encourage folks to peruse the summary to explore a little bit. One part that people here may find exciting is the fusion research funding:

Sec. 10105. Fusion Energy Research. Subsection (a) amends section 307 of the Department of Energy Research and Innovation Act (42 U.S.C. 18645) by authorizing $50,000,000 per year for FY 2023 through FY 2027 for research and development of fusion materials. It extends the authorization for inertial fusion research and development, alternative and enabling concepts, and the milestone-based development program through FY 2027. It authorizes the establishment of at least two national teams to develop conceptual designs and technology roadmaps for a pilot fusion plant, and authorizes $35,000,000 for FY 2023; $50,000,000 for FY 2024; $65,000,000 for FY 2025; $80,000,000 for FY 2026; and $80,000,000 for FY 2027 for these activities. It directs the Secretary to establish a high-performance computation collaborative research program and an associated innovation center in high-performance computing for fusion. It directs the construction of the Material Plasma Exposure Experiment including $21,895,000 for FY 2023 and $3,800,000 for FY 2024 to carry out the project. The subsection also authorizes an upgrade to the Matter in Extreme Conditions endstation at the Linac Coherent Light Source.

This is too broad of a reading. Unfortunately despite the mission statement of organizations they are limited by their own laws and rules. In this case this is a narrowing of a particular reading of a paritcular rule that was used to limit greenhouse gas emissions from power plants. See https://reason.com/volokh/2022/06/30/supreme-court-rejects-b... for more details

For those looking to get an objective understanding of this decision I found this article useful[0]. The gist of it is that this is more about preventing future rules to be put in place rather than changing anything that the EPA is actively enforcing. Essentially the EPA cannot force the shut-down of coal fired power plants (or other high emission energy sources) using the Clean Air Act.

As someone very pro renewable energy obviously I would prefer a different outcome, but the good news is that these types of power sources are just plain uneconomical these days, so their shutdown is going to happen anyways. Perhaps renewables won't have as many regulatory assists as we hoped, but the good news is that they can stand on their own, and the clean power industry keeps building better systems then capitalism will take care of the transition for us.

Unless you are being extremelly pedantic than I would agree with the parent. The thesis of the article is essentially "Solar and Wind aren't the way forward, Nuclear is the way". While it is reasonable to acknowledge the solar and wind still face many challenges, the parent is pointing out that they are already doing a good job in accelerating decarbonization and Nuclear, while appealing, isn't the clear cut winner the article is saying it is.

Interesting product, I'm curious how the ongoing fees (operations and maintenace, etc.) are managed. Does the provider of the installation take a cut? Does Legends do the O&M?

There is a major difference between long term investments (selling federal land leases) and encouraging short/medium term supply (use of existing leases, encouraging more oil production from existing facilities).

I see no incoherence in denying _new_ leases, since O&G sector is already sitting on many existing leases [1], and in the _long_ term I think we need to drastically reduce the production of oil and gas to lessen the damage of climate change. The moves to deny new leases is in line with those views/meets my expectation of encouraging medium-term supply without a long-term commitment to fossil fuels.
