> When they made that announcement, they already knew.

Yep, the ongoing convergence made that pretty clear. The emphatic "No" was to reassure 2018's macOS developers that they wouldn't need to rewrite their apps as xOS apps anytime soon, which was (and is) true 7 years later.

This is the same session where Craig said, "There are millions of iOS apps out there. We think some of them would look great on the Mac." and announced that Mohave would include xOS apps. Every developer there understood that, as time went on, they would be using more and more shared APIs and frameworks.

> The problem isn’t them making iOS (or iPadOS) more like macOS, it’s them doing the reverse.

That ship has sailed, but it's also completely overblown.

DOS International was a German magazine in the early nineties with excellent technical explanations and program listings. One of them was a super compressor that used your recursive technique. I didn't quite understand the details that were given in the description of the algorithm (I blamed my mediocre understanding of German), but it sounded legit.

So I spent a good hour to type in a page of impossible to follow C code with obscure numbers in lookup tables and all it did when I ran the program was to print out "April 1., April 1.".

The problem is the methodology they use to hold them out. For a truly independent validation set, they need to hold out the material before augmentation, not after. If you hold out after augmentation, then you leverage biases from the training regimen already and hence you artificially boost your model's performance. This is not sufficient to demonstrate your model is generalizing properly.

In analogy: instead of taking leaves off of different trees, they are taking leaves from different branches from the same tree.

They do, but this is misleading due to a number of caveats

First one is that they don't use btrfs own RAID (aka btrfs-raid/volume management). They actually use hardware RAID so they don't experience any of the stability/data integrity issues people experience with btrfs-raid. Ontop of this, facebooks servers run in data centers that have 100% electricity uptime (these places have diesel generators for backup electricity)

Synology likewise offers btrfs on their NAS, but its underneath mdadm (software RAID)

The main benefit that Facebook gets from btrfs is transparent compression and snapshots and thats about it.

I've been working with Opus 4 on ultrathink quite a bit recently and did some quick tests with Sonnet 4.5, I'm fairly impressed, especially with its speed but I did feel it was a lot less strict with my rules, existing patterns, etc. compared to Opus 4.

Maybe it's better with a better CLAUDE.md structure? I don't use those a lot, just telling Opus to think got 'good enough' results I guess. Not sure.

I hope there's an Opus 4.5 coming out soon too. In the meantime I'll see if I can get to do better with some extra prompting or I'll go back to Opus of if I don't need the speedier responses.

Spaces such as online open-source communities? This is nonsensical, listen to yourself. Your anti-human bias shows and it's actually disturbing. What spaces are you even talking about and why do you think people that look, act, talk and think exactly like their members should be barred from them?

Got it, demanding human rights apply to trans people is now an "ideological stance". The American Overton window is so far right, it's crazy people can hold such views and think they're being reasonable.

EU and US testing criteria are very different - in the US, motor vehicles leaving the roadway and impacting stationary objects is the top source of traffic fatalities. In the EU, it's pedestrian impacts (which makes sense corresponding to the urban vs rural environments in each).

The EU has very stringent testing for pedestrian safety: https://www.euroncap.com/en/car-safety/the-ratings-explained.... One of the tests is literally just taking a foam ball, pressing it on spots all around the front of the car, and looking for hard, sharp corners.

The cybertruck is a steel box made of sharp corners. It was never, ever going to be allowed on European roads - and the US Government here is saying they are not even going to fight for the rarest exception.

I’m not saying it’s particularly competitive, I’m saying claiming it cost 100M$ to run Qwen is complete lunacy. There is a gulf between those 2 things.

And beyond pure performance competitiveness there are many things that make it hard for Cerebras and to be actually competitive: can they ship enough chips to meet the need of large clusters ? What about the software stack and lack of great support compared to nvidia? Lack of ml engineers that know how to use them, when everyone knows how to use CUDA and there are many things developed on top of it by the community (e.g triton).

Just look at the valuation difference between AMD and Nvidia, when AMD is already very competitive. But being 99% of the way there is still not enough for customers that are going to pay 5B$ for their clusters.

I never had any interest in wearing a watch to bed. Still don’t, although theoretically I could charge it for a few minutes in the evening to make that possible.

The Watch has helped me lose 30 pounds, has significantly helped motivate me to exercise more, and has let me keep my phone on silent mode for at least 5 years now. For me, it’s a great device.

All this word salad and smooth talk about the "middle ground" just worries me even more. We have been living in such an unusual period of peace, prosperity and freedom that the pampered, wealthy segment of the Western people is considering children seeing porn as a some sort of catastrophe, warranting extreme countermeasures. However, meanwhile in the actual reality, people are still being killed on the basis of sexual orientation.

I would support reasonable measures to block children from accessing pornographic content, but making people upload government IDs or biometric data does not belong to the realm of what is reasonable.

> Lesson: Test backups continuously so you get immediate feedback when they break.

This is a very old lesson that should have been learned by now :)

But yeah the rest of the points are interesting.

FWIW I rarely use ZFS native encryption. Practically always I use it on top of cryptsetup (which is a frontend for LUKS) on Linux, and GELI on FreeBSD. It's a practice from the time ZFS didn't support encryption and these days I just keep doing what I know.

That's fascinating. I generally mix in-the-box, so my mixes are close to commercially-ready before mastering, but I've experimented with a few of the "one-click" mastering solutions and they just haven't been it for me (Ozone's presets, Landr, Distrokid.) I've currently been using Logic's transparent mode as a one-click master which has been slightly better, but this sounds really compelling. I generally just want 16-bit 48 KHz masters anyway, so no need for Atmos. I'll have to try this out. Thanks for sharing!

Actually a few hundred thousand have been killed, the ~60k figure from the Gaza health ministry is just the deaths they've been able to actually confirm, which is just deaths at hospitals (which is why that number has grown so little this year, because the vast majority of hospitals in Gaza have been destroyed by the IDF).

See for example this July 2024 estimate of close to 200k deaths (https://www.thelancet.com/journals/lancet/article/PIIS0140-6...) or this more recent estimate of over 600k (https://arena.org.au/politics-of-counting-gazas-dead/ )

Sure, they're estimates not proven statistics, but the situation on the ground means it's impossible for anyone to have an accurate count. What's important is that we don't look at the relatively small (yet still depressingly large) number of confirmed deaths of known named people, tracked by the Gaza health ministry, as if it's a count of the actual number of deaths. Hell, even the IDF recently claimed that there have been 90k deaths (when they were boasting that they had killed 30k Hamas fighters and that they had "only" killed 2 civilians to every 1 Hamas) - and, setting aside the IDF's track record of lying and their incentive to claim less civilian deaths than reality, even if they were telling the truth that would still be limited to deaths they were actually able to track and confirm, not the many other deaths that weren't officially recorded.

I am afraid that despite all these options for containers, I still use my Vagrant scripts that build whole VMs based on my own schemes, use an apt package cache on the host and manage .ssh/config for me to make VSC remotes more seamless.

Almost all my stuff still runs on simple VMs because I cannot rely on my clients to take on more complex cloud infrastructure and I don't want to be stuck managing all of the things forever, so my life involves building customer VMs from build scripts that are adequately similar to my Vagrant boxes.

I use the VMs a lot for simple tests (e.g. of wordpress plugins and themes) so I have gone to the trouble of setting up Avahi with alias support, adding options for mailhog, different databases, different webserver setups I use for WP or Laravel or node.js, setting up an automated WP install etc.; so there are two or three starting configurations. I even had one for Magento before I realised I could be a lot happier without Magento in my life.

I guess it looks a fair bit like devcontainers now, and I should consider migrating over to that. But it's solid and under my control and that counts for a lot.

You must write very elaborate prompts for 10 minutes to be worth the wait. What permissions are you giving it and how much do you care about the generated code? How much time did you spend on initial setup?

I‘ve found that the best way for myself to do LLM assisted coding at this point in time is in a somewhat tight feedback loop. I find myself wanting to refine the code and architectural approaches a fair amount as I see them coming in and latency matters a lot to me here.

"But, imagine what this does for inflammation. That is 7 pounds of fluid you are no longer carrying and pumping against. It's basically a gallon. The first round of keto I did, I lost a ton of weight the first month (~20 lbs), and my blood pressure plummeted to the point where I was dizzy all the time, and I had to supplement with salt and magnesium."

Are you saying losing the waterweight decreased your blood pressure?

AFAIK the water lost was bound to the carbohydrates being stored. It's not in liquid form.

YTD, the US has spent approximately $4.5T[1] on health and human services, of which approximately $1.9T are health-related alone.

This is not correct and a gross simplification of the true issue.

All aircraft with underslung engines have similar pitch up tendencies to varying degrees and different handling characteristics between models are fine.

As seen with 757/67, 777/787 and A330/40/50 sharing type ratings despite being massively different aircraft.

> As the nacelle is ahead of the C of G, this lift causes a slight pitch-up effect (ie a reducing stick force) which could lead the pilot to inadvertently pull the yoke further aft than intended bringing the aircraft closer towards the stall. This abnormal nose-up pitching is not allowable under 14CFR §25.203(a) "Stall characteristics". Several aerodynamic solutions were introduced such as revising the leading edge stall strip and modifying the leading edge vortilons but they were insufficient to pass regulation. MCAS was therefore introduced to give an automatic nose down stabilizer input during elevated AoA when flaps are up.

http://www.b737.org.uk/mcas.htm

The feeling of the aircraft is not the problem. The stall characteristics not complying with the regulation is.

> then you know why CoC came about

I've been on the Internet when flamewars were common, and CoC weren't a thing yet.

CoC (along with committees) are a very recent thing. They weren't introduced until certain people started exercising moral blackmail onto projects, people and organizations by pushing political topics into technical discussions.

Back in the days of flamewars there were a few rules and pretty much just moderators to enforce them.

Rules were simple, you were usually banned if your messages were either not civil (and here again, the bar was high), if your contributions were comically off-topic or if you spammed the forum/newsgroup/mailing list.

TLDR: busy, lazy, not properly incentivized. I'll get right on that, boss... or is it Officer? I already said: time. I'd like to spend more of my time with triage before I disrupt others, particularly the developers. I don't mind y'all so much :)

It's reproducible, the scope needs to be reduced. With work. A lot of testing and variable change/reduction. More than I care for.

Before you assume that LDL isn’t a good biomarker, read the entire article. Specifically this section:

> Why? In some ways, cholesterol has become a victim of its own success. We now screen the whole population for high cholesterol, give statins to those with high LDL (or ApoB), and so then the majority of people who end up having heart attacks have lower cholesterol than they would naturally have

In other words, in the study population patients who would have had high LDL were likely to be on statins. The had a lower measured LDL value even though they might still be consuming a poor diet and living an unhealthy lifestyle, for example. Statins don't fix everything about poor diet and lifestyle, but they do help with cholesterol.

So don’t go throwing LDL out yet. It’s still the best measure we have, though you should obviously know that LDL measured while on statins is lower than it would be normally.

The headline, therefore, is somewhat clickbait from a company trying to sell these tests to you outside of your insurance. I recommend checking your insurance to see if the tests would be covered before you go the self-pay route.

Edit to add: If your doctor won't order hs-CRP for some reason, you can order it from sites like privatemdlabs.com for $50 (less if you take their 25% off coupon).
by brandonb | 2025-09-30 22:07:53+00:00
Note that the $190 panel includes not just hs-CRP ($59), but also the other major heart health biomarkers: ApoB ($69), Lp(a) ($49), A1c ($39), lipid panel ($59), eGFR ($99), other biomarkers, and a video consultation with a doctor to actually explain the results and what to do about them.

> If you have a factory, idle equipment costs you money

True, but that isn't the whole story. Where I live most factories have their own snow removal equipment even though it is only used a few days per year and sits idle the rest of the time. While it costs money to have it sit idle, it costs even more to have the whole factory idle until the snow melts. (or the people you hire get around to your factory).

> Right now our factories have only specialized robots, but they still have lots of people because it's too expensive to do the remaining tasks with specialized robots.

And when they decide people are too expensive they replace them not with general purpose robots but more special purpose robots.

> A very large number of identical robots will probably end up costing less than smaller numbers of lots of special purpose robots.

Maybe. It isn't clear. A general purpose robot could be more expensive - I only need one while I "need" one vacuum robot per floor meaning that special purpose robot scales better. And that vacuum robot is also a lot simpler meaning it will be cheaper to own 2 than to have 1 general purpose robot.

The question then is the general purpose robot cheaper because you only have 1 instead of an army of special purpose robots. We do not know (today).

There is a theory that cholesterol elevates in response to circulating endotoxin (dead bacteria cell walls). Lipoproteins can bind to the endotoxin, and clear it or at least stop immune cells from reacting to it. This response increases LDL, but decreases the immune activity that would otherwise be created by letting the endotoxin circulate. So LDL is a defense mechanism against the body's own response to circulating endotoxin as well as the endotoxin itself.

If true, that would explain the link between inflammation, LDL, and heart disease. It would also imply that the circulating endotoxin is the thing to target. I wonder where all the dead bacteria cell walls are coming from, probably where the dead bacteria are. That, of course, is the gut.

I don't remember the original paper, but I found something that at least explains the theory here.

And how does it do that? By looking at the words and seeing that they rhyme?

An LLM is not capable of subtext or reading between the lines or understanding intention or capability or sarcasm or other linguistic traits that apply a layer of unspoken context to what is actually spoken. Unless it matches a pattern.

It has one set of words, provided by you, and another set of words, provided by its model. You will get the bang average response every single time and mentally fill in the gaps yourself to make it work.

There are at least 3 fundamentally different kinds of diff:

* Single-dimensional. Diffs of text lines are just this.

* Multi-dimensional. Diffs of words or characters are usually going to be this since lines still matter, but there are multiple approaches (line-first? weighted tokens?).

* Tree-based. Unfortunately, these are woefully scarce and poorly documented.

For text diffs, it's nontrivial to get the "missing newline at end of file" logic working.

For tree diffs, consider that for HTML something like `<p>x</p><p>y</p>` should be unmergeable, whereas `<b>x</b><b>y</b>` should be mergeable.

(Aside: the blind promotion of `<em>` and `<strong>` did great harm to the notion of semantic HTML. Most things people use italics for (book titles, thoughts, foreign words) are explicitly things that `<em>` should not be used for.)

Anthropic's Claude added code execution last month. It's architecturally different from existing AI coding tools—runs in isolated containers, handles file I/O, provides full debug loops.

Yeah, but then you run into scenarios where A+D is tested and ready, but B and/or C are not. Git does give you tools to separate them, but most people don't like doing that for various reasons.

IMHO, it may be more natural, but only during development. Trying to do a git bisect on git histories like the above is a huge pain. Trying to split things up when A is ready but B/C are not is a huge pain.
