You are completely wrong because over the long term, thermodynamics isn’t just a theory — it’s the governing principle. No matter how “inefficient” the body is at using or storing energy, it still obeys conservation of energy. If you consistently burn more calories than you consume, your body has to draw on stored energy (fat, muscle, glycogen, etc.) to make up the difference. That’s not up for debate — it’s been proven across thousands of controlled metabolic studies.

Yes, the short-term details can vary — sometimes you’re burning glycogen, sometimes fat — but over weeks and months, a sustained calorie deficit always results in weight loss. The body doesn’t magically create energy out of thin air because its “efficiency” fluctuates. You can argue that diet composition and hormones affect how easy it is to maintain that deficit, but not the fundamental physics behind it.

So while you’re right that biology is messy in the short term, thermodynamics still wins every single time when you zoom out.

It doesn't matter what source you are burning your energy from at any given time for long term weight. Let's say you eat a bunch of carbs and then you go for a run, well you're probably going to burn those carbs off first (depending on how hard you run and other factors). Which according to you doesn't matter since it's not burning stored fat. But if you didn't go for that run then those carbs would turn into fat later.... And if you go for a really long run (or you take it easier) then you will start burning the stored fat. But either way it doesn't actually matter because calories in / calories out still is the determining factor.

You don't have to read very far to see the details.

> 45% of responses contained at least one meaningful error. Sourcing [...] is 31%, followed by accuracy 20%

And you can see the reason they think this is important on the second page just after the summary.

> More than 1 in 3 (35%) of UK adults instinctively agree the news source should be held responsible for errors in AI-generated news

So of course the BBC cares that Googles summary said that the BBC cites pornhub when talking about domestic abuse (when they didn't), because a large portion of people blame them for the fact that a significant amount of AI generated crap is wrong.

> url "$my_url" parses a URL into its parts. I use this about once a month to pull data out of a URL, often because I don’t want to click a nasty tracking link.

This sounds pretty useful!

Coincidentally, I have recently learned that Daniel Stenberg et al (of cURL fame) wrote trurl[1], a libcurl-based CLI tool for URL parsing. Its `--json` option seems to yield similar results as TFA's url, if slightly less concise because of the JSON encoding. The advantage is that recent releases of common Linux distros seem to include trurl in their repos[2].

In the grand scheme of things, I don't really have any delusions with regard to with war. I am vehemently opposed to it, yet simultaneously think it's inevitable and will probably stay with us forever. When two sides have fundamental and irreconcilable differences, a physical altercation is likely. On the level of nations, this is war. And in war an unfortunate reality is that innocents will die.

But what Israel is doing isn't war and the innocents they're killing aren't unfortunate 'collateral damage.' They're primarily and purposefully killing civilians that had absolutely nothing to do with what aggrieves Israel, exactly the same as Nazi Germany was killing Jews who had absolutely nothing to do with their grievances. And they're doing this only thanks to American weapons and technology.

After all is said and done, Israel will claim victory, yet Hamas will likely be dramatically larger than ever, at least if there are any Gazans left, simply because each person whose brother, father, or child was killed by Israel is now going to hold a life-long death grudge against Israel, in the same way that Jews still seek out what few remaining Nazis there are, when they aren't getting standing ovations in the Canadian parliament at least (more of those 'foundational human rights' being displayed). And this is because genocide has nothing to do with war - it's something uniquely abhorrent.

Meta's AI division cuts feels like a classic case of corporate reshuffling—painful for those affected but strategically predictable. I find it interesting how they're doubling down on superintelligence while trimming other AI teams, which really shows where they're betting their future. That $27B data center deal right before these layoffs makes me wonder about the realignment of resources—are they choosing brute-force computing power over diversified research?

I think the increasingly widespread attitude that only open source software is good and trustworthy increasingly annoying and problematic.

Building software takes time and resources. Experienced show that most open source projects do not make enough money to make the resource investment worthwhile, much less the time investment.

I generally like people being able to out food on the table, and if that means I have to pay for their software to use it or get updates, then I am happy to do so if that software is of value for me.

That of course doesn‘t mean I appreciate unnecessary vendor lock in, hostile subscription models, etc. All of these things are common with proprietary software, but they are not inherent to it.

Obsidian is a great example. Easy to takeout open formats, generous licensing model and no aggressive licensing implementation that makes it impossible to use the software offline. The team behind it seems to be able to make a living and people can still feel safe about the access to their notes.

Even if its not open source, it would be great progress if we‘ve had more software like obsidian

At this point, just accept electric motorcycles/scooters are a distinct category that you'd like to accept and promote, and get rid of the vestigial pedals.

In my country, our govt is promoting e-cycles, and they are about ~ USD 1,000, after being imported from China. They have similar specs to these 'bikes' (range-wise) and I think they are better vehicles, both in price and in utility.

https://www.pave.gov.pk/vehicles

No need to add fake pedals or create a useless 'bike' frame when people are earning for a scooter/motorcycle. Create easier licensing/registration options and you will see adoption rise for the vehicles people truly want.

Thanks for this. 10$/kWh would be insane as an aspirational number but are these manufacturer costs or grid scale buyer costs or retail costs for end user in EVs/homes? To make it more specific, what % drop in per-kwh costs for grid scale storage should energy developers expect to see over the next 2-3 years due to sodium ion? Trying to nail down a best-guess percentage drop to get a feel for how big this is going to be.

Well done Steinberg/Yamaha.

At the same time Steinberg also open sourced their ASIO audio hardware interface standard but under GPL3. GPL2 here would have made more sense to me to align with the Linux kernel GPL2 only licensing. So why GPL3? Other commenters here have mentioned OBS, and OBS is "GPLv2 or later" so sure that works for them. Not being GPL 2 and missing on the Linux kernel just surprises me.

I have been using the nice cwASIO (https://github.com/s13n/cwASIO) re-implementation of the ASIO SDK, it's MIT licensed. https://github.com/s13n/cwASIO. It's nice there just to see something more up to date than the ancient ASIO SDK documentation. I would love to see the Steinberg ASIO SDK updated and improved, if you are listening Steinberg folks: nobody cares about the history of ASIO on Macs or Silicon Graphics Workstations, just dive in and get deep into the weeds of ASIO on Windows, and include lots more sample code, especially covering the ASIO device enumeration mess on Windows.

I started using git when my employer still used svn. This was possible because `git-svn` was so good and it seamlessly allowed me to use branches to do development while still committing to svn's trunk. I think jj is trying to do something similar: jj-unaware tools work reasonably well in colocated jj repositories, and jj-unaware peers (CI tools, etc) work exactly as they did before.

I do agree that you can't really use jj without also knowing "a fair amount" about git, but notably you never need to use the git cli to be an effective contributor to a github project, which is basically the same as `git-svn` was back before git got popular.

> That strikes me as the right thing to do

Yep, and it's there for very goos reasons. However if you don't know about it, it can be quite surprising and challenging to debug.

Also it's annoying when your phones permissions optimiser runs and removes the location permissions from e.g. Google Photos, and you realise a few months later that your photos no longer have their location.

Regulation might be one part of the equation, but I would like to understand a bit deeper on how much of cost driver it is.

Healthcare is heavily regulated in some countries and less in others. It should be possible to get some comparisons.

I somehow feel that making many humans healthy is fundamentally a really hard problem that gets harder every year because the population ages and expectations rise. It feels to easy of a talking point to put it all on regulation.

How is your point relevant to the security risks of community plugins?

But also - no, they aren't, they use plugin-customized non-standard markdown format, so while the extension is the same, you can't view/edit them with anything just like you can't edit Word xml files with notepad (of course, it's not as extreme as Word xml, unless you're an extreme user of custom plugins)

Subtleties are not necessary to be very useful. They, are just real subtleties. :)

> > “for true {...} and for {...} are not eqivalent”

> So what? The compiler will tell you the first time you try to run that “for true” abomination that it is invalid code.

It teaches you know that, when you write

func bar() int { for true { ... } return 0 // whatever }

You can write it as

func bar() int { for { ... } }

The compiler will not teach you this. ;D

Usefulness might be subjective. Personally, the last two subtleties mentioned in the article are useful for me too.

You may find some useful (in your opinion) subtleties in the Go Details and Tips 101 book: https://go101.org/details-and-tips/101.html, and some since-Go-1.22/3 ones here: https://go101.org/blog/2024-03-01-for-loop-semantic-changes-... and https://go101.org/blog/2025-03-15-some-facts-about-iterators...

The scary thing is that nowadays everything is backdoored. And developers/product owners can even don't know about it. Obsidian is an electron app, thus uses npm, and with npm we now get like at least one malicious package per month. If they have package autoupdate it's just a matter of time and effort for an attacker to plant something shady there. This could be simple crypto-stealer, or this could be a way to access people's personal vaults.

Dandadan is as far as you can get from “poor animation” but it definitely has a specific mix of lo-fi aesthetic animated exceedingly well, and they’re using Adobe Animate, aka Flash.

Animation doesn’t feel fast if it’s too many FPS or too steady, anyway, ironically and counterintuitively. You can’t do everything on the ones and twos.

To your point about Dandadan’s intro, it’s jam packed with references, which is another kind of skill in and of itself:

https://www.youtube.com/watch?v=5sUaK0xahBU

Chainsaw Man is in that same vein, and is another Science Saru production. I’m looking forward to seeing what they will do with the Ghost in the Shell franchise next year.

https://en.wikipedia.org/wiki/Science_Saru

I get what you mean though regarding Dandadan’s animation style; it has a very hand drawn manga vibe, and the detail is minimal yet finely balanced against the overwhelming amount of noise and visuals. It’s like a slapdash superflat.

https://en.wikipedia.org/wiki/Superflat

On a side note, as an anime fan, MBS is doing great work lately. I liked Witch Watch much more than I expected to, and that’s a much better show than the genres involved would lead one to expect.

I think very few manufacturers are optimizing for that. The move to integrated batteries for most portable electronics happened when the price of the battery plus charging ICs became lower than putting in a battery holder. Doing battery holder is currently simply more expensive, design is more complex putting it together is more complex. The cost are not intuitive, you can get 10+ microcontrollers for a price of a single physical on-off switch.

To my understanding the lawsuit is not about Reddit's content or copyright infringements but in more detail about using proxy farms and other measures to get Reddit content via Google's results and thus breaking the DMCA and they go against services providing the infrastructure to do so.

A bit comparable to how pressure was put onto payment providers to restrict sites with extreme adult content.

Side note: I find it super interesting in the filing https://fingfx.thomsonreuters.com/gfx/legaldocs/xmpjezjawvr/... that Google was able to provide them with the exact number of automated requests broken down by company.

My thinking and experience went kind of the opposite way. We are focusing so much on making it effective and hard ... that we removed all pleasure from exercising and sport. Of course it takes a lot of self control to go do it, when the whole experience actually massively sux and no matter what you do, it is not enough. And of course then you will give up on that once you are under pressure or stressed or have a lot of work.

The people who I know personally who move physically a lot ... like it. They need additional self control to skip the sport session and go clean the house. They either found activity that they fall in love with, the sport doubles as social outlet for them or they made it pleasant by tweaking how it is done.

> Statistically, nobody is a runner on their first few years. It takes time. And is hard.

It does not have to be. The first beginner period of a sport if normally the most pleasant one - you are getting quick improvements at first. Unless of course you go all hard to yourself and let all the motivation being eaten by guilt that you can run only for 4km instead of 15km yet.

Or, you dont have to run which is indeed inherently boring for quite a lot of people. You can roller skate instead. You can go for very long walk spending 2h listening to podcasts and shows.

The second is a real problem even with completely unique applications. If they have UI portions that have lookalikes, you will get flagged. At work, I created an application with a sign-in popup. Because it's for internal use only, the form in the popup is very basic, just username and password and a button. Safe Browsing continues to block this application to this day, despite multiple appeals.

Oh: I was surprised/saddened that the article mentioned Cake's bankruptcy, so I had to check and it seems the company/assets and a lot of staff was acquired by Norwegian company Brages [1] so it kind of still exists, at least. Not sure if that means they no longer sell in the US, though.

I've tried using various AI tools and models over the past couple of years, but honestly it feels like it gives me a false sense of confidence. Plus, the time I supposedly save building things gets eaten up debugging, correcting, improving the AI-generated slop.

Am I using the tools wrong or are others finding the same thing?

A high quality CRT wouldn't have a lot of those issues. And a lot of content wasn't proofed on anything, it's raw camera output. Either way if something came from a camera there's no intent to have half of CRT's problems, and they very likely didn't do any compensation for those problems that would look bad on a better screen.

Wanting the whole package of CRT flaws isn't just playing a record, it's playing a record with a cheap needle. Go ahead if it feels more nostalgic or right to you, and I wish you luck in finding what you want. But I don't think it adds anything, and to some extent it detracts from the original.

Software being open source almost always makes it more trustworthy, and I'm glad that more people are picking up on this over time.

> I generally like people being able to out food on the table

Completely agreed, and this makes for a frustrating paradox.

I don't use Obsidian because it's closed source, but I don't think it's evil or anything. Conversely, I pay for Immich, and I hope their model is sustainable.

So the DNS records if-stale-then-needs-update it was basically a variation of the "2 Hard Things In Computer Science - cache invalidation". Excerpt from the giant paragraph:

>[...] Right before this event started, one DNS Enactor experienced unusually high delays needing to retry its update on several of the DNS endpoints. As it was slowly working through the endpoints, several other things were also happening. First, the DNS Planner continued to run and produced many newer generations of plans. Second, one of the other DNS Enactors then began applying one of the newer plans and rapidly progressed through all of the endpoints. The timing of these events triggered the latent race condition. When the second Enactor (applying the newest plan) completed its endpoint updates, it then invoked the plan clean-up process, which identifies plans that are significantly older than the one it just applied and deletes them. At the same time that this clean-up process was invoked, the first Enactor (which had been unusually delayed) applied its much older plan to the regional DDB endpoint, overwriting the newer plan. The check that was made at the start of the plan application process, which ensures that the plan is newer than the previously applied plan, was stale by this time due to the unusually high delays in Enactor processing. [...]

It outlines some of the mechanics but some might think it still isn't a "Root Cause Analysis" because there's no satisfying explanation of _why_ there were "unusually high delays in Enactor processing". Hardware problem?!? Human error misconfiguration causing unintended delays in Enactor behavior?!? Either the previous sequence of events leading up to that is considered unimportant, or Amazon is still investigating what made Enactor behave in an unpredictable way.

If you're a Linux user you might like Firejail for this.

firejail --appimage --net=none --private=~/path/to/jail ~/path/to/Obsidian.AppImage

--private=~/path/to/jail limits access to your home directory to ~/path/to/jail and when you don't want Obsidian to have internet access you can take it away with --net=none.

I wouldn’t hold not being on the Mac App Store against it. The MAS is sort of a failed ecosystem with very low usage/engagement, and all the downsides of the iOS store like potentially lengthy review times (can be a lot longer than the iOS store since it seems to play second fiddle) and arbitrary capricious rejections when you’re just trying to ship innocuous bug fixes to users.

I know what you're talking about, but I think you happened to pick a bad example to pick on here. This wind tunnel analogy resembles a common criticism of the prior experiments that were done by Google and others over the last few years. Those experiments ran highly unstructured, arbitrary circuits that don't compute anything useful. They hardly resembled the kind of results that you would expect from a general purpose, programmable computer. It's a valid criticism, and it seems like the above commenter came to this conclusion on their own.

To that comment, the present result is a step up from these older experiments in that they a) Run a more structured circuit b) Use the device to compute something reproducible (as opposed to sampling randomly from a certain probability distribution) c) The circuits go toward simulating a physical system of real-world relevance to chemistry.

Now you might say that even c) is just a quantum computer simulating another quantum thing. All I'll say is that if you would only be convinced by a quantum computer factoring a large number, don't hold your breath: https://algassert.com/post/2500

Yamaha is an old company found on very different ethos compared to others. Their history is interesting, too: https://www.youtube.com/watch?v=y6t5F3cb810

It's worth a watch.

On another note, it's very telling that companies that protect their "hey! we do this interesting thing, gonna buy?" character survives for much longer compared to companies which say "we can earn a ton of money if we do this".

The companies in the second lot does a lot of harm to their ecosystems to be able to continue existing.

> I ended up going with Logseq for many reasons - yes it appears to be less mature however that doesn't mean that it is inferior by any measure (and open-source)

If I remember correctly it was inferior to Obsidian because Logseq used a proprietary format. Yes, it was/is officially markdown but not in a format that is easily transferred. I don't know if it changed but Logseq documents where literally just a big Markdown list if I remember correctly.

Personally I do see the problem with closed source solutions but the real problem with Obsidian are AFAIk the plugins and not the App itself. I mean: They have a long way to go to be even remotely as evil as people at Google or Microsoft. But if that ever happens I simply walk away with my .md documents.
