> They mention it buffers with a gain factor of 0.1, but I don’t understand how the four op-amps play together to eliminate the hiss.

I'm not entirely sure, but it appears that this is setup to amplify the ground noise.

I'm also not entirely sure why you would want a gain of 0.1, you would probably want to preserve as much amplitude information as possible.

Also the power circuit on the left shows a resistor ladder with 9V over a 1k resistor on one side, and the same for the other. 9 / 1000 = 9mA, x2 is 18mA. Added with the amplification of noise, I can see where 25mA may come from.

> Yeah, and two op-amps for the ground filter has me stymied as well.

I think this is because it's the ground for both the left and right channels, which is potentially two op-amps worth of power and you don't want this dumped through the headphone jack.

I haven't tested this, but would probably go for a simpler design like this:

Don't be too amazed though. What he states isn't the scientific consensus. Persistent sleep deprivation is harmful to human beings, and you don't "reset and go back to well-rested again". Some sleep deprivation can be endured though, as any parent will tell you -- I know I wasn't "well rested" afterwards. I mostly was grumpy and very slow to think.

I went to a a top tier US public high school, was top 20% in my class and ended up going to a state university.

Over 15 years in finance, including working at multiple top 10 hedge funds, I've gotten to work with a lot of top Ivy and non-Ivy graduates.

I've come to a couple conclusions:

- There doesn't seem to be a difference in the smartest people from an Ivy and the smartest people from state schools

- Going to a Ivy or top university definitely gives you an advantage at some firms and there is something to be said for the network these schools have both from an alumni perspective but also from people you went to school with.

- I would argue that state schools are a better preparation for "life in general" b/c you learn how to deal with a larger variety of people, organizations, social backgrounds etc than you do at an Ivy

- There are a LOT of senior people at firms that prioritize Ivy league graduates who did NOT go to an Ivy league school. That would lead me to believe that there are many paths to success outside of getting an Ivy league degree.

I read the article, and it says:

I also read the archived reference article [0]:

> In the Netherlands, maritime traffic in Rotterdam was halted as the authorities closed the giant Maeslant surge barrier, which guards the entrance to the largest port in Europe, for the first time since its construction in the 1990s

Is the title missing a [2007]? Or is there a current event happening as well that has been misidentified as the first occurrence of this?

>Yes, US has a huge military and it benefits from it, but I would say the primary beneficiary of this military are the friends of US who now don't have to spend money on military.

That makes no logical sense. Why would the US invest so much money to protect its allies, if it weren't the primary beneficiary of it's giant military budget, and instead would mostly benefit its allies and not itself? The US always puts itself and own interests first.

The massive military sector is what gave birth to US's tech sector and the massive surveillance apparatus the US has at its disposal, and allowed it to own the aerospace sector too. All that give the US the biggest soft and hard power globally, and it also trickled down to its economy and to other sectors as well.

Protecting it's allies is just a happy side effect of them fitting underneath the giant umbrella the US has built primarily for itself, and it will never give it up because protecting its allies was never the main objective, but projecting its power.
I would expect heating to be one of the electricity use that you _can_ adapt the easiest. First by using heatpumps instead of resistors, and then with some inertia management to buffer (e.g. water tanks, or something)

Isn't that the case?
They are nice. Like a small PC. There's even a company making an (overpriced) mini-ITX compatible PC style motherboard with it.

I just downloaded and installed and I am really impressed. I liked the concept of math blocks though it took me a few seconds to figure out how to change a new block into a math block. This note at the top wasn't clear to me:

⌘ + L Change block language

The phrase block language didn't trigger my "change the type of block" thinking. I might slightly rephrase like:

⌘ + L Change block language (Math, Markdown, etc.)

Otherwise, I think this is a great "scratches an itch" type project. Congrats!

I'm unconvinced by this argument. First of all, why US intelligence agencies and not let's say Czech intelligence agencies? Or, more likely, nobody owns the majority of the network and nobody wants an arms race?
Of course. But in many other areas involving things that are harmful to children we require others to do things that make it easier for the parents.

A couple examples are that we require purveyors of cigarettes and alcoholic drinks to check customer IDs and not sell to children, and we require annoying childproof packaging on many products.

So we've generally already accepted that it is not just parents who should have some responsibility toward children.
Why not? What’s the point of the state paying for higher education? I’d say encouraging social mobility and making more people into high value creators.
I don't understand the hate against Timo. It's pretty obvious from the article that he only thought about the recipient side and not about the sender (postfix). Postfix does behave wrong (according to e.g. RFC 2822 section 2.3), but it still was not in scope of the article.

The disclosure did go to the parties who he (or SEC Consult) seemed vulnerable.

Hey! Nice app, I've always had scratch pads around for things like this and never had a particularly good solution for them. Soulver is nice but too maths focused, a tab in VSCode in nice but it's a pain to manage multiple buffers for different languages. I like the feature set here.

A few bits of feedback for potential improvements or clarifications...

- I couldn't find the shortcut to change the language until I hovered over the status bar element for it. It should have a menu item with the keyboard shortcut on it.

- Toggling light/dark mode doesn't live in the status bar in any other app I know, probably best to put it in settings.

- Doesn't respect the system light/dark mode, it should by default (but perhaps with an app specific override as some people like that).

- Check for update doesn't live in the status bar either in any other app I've used, this could be in settings.

- If there's not enough stuff to put in a status bar, maybe drop the status bar? It feels like things have been scraped together to justify having it.

- The green branding is ok, but it's quite a strong personality for an app to have. Do you want the app to have a strong personality? (Nothing else about it suggests so). Perhaps consider a more neutral palette that fits in with macOS more, or perhaps several choices for accent colour including a neutral option.

- 427MB is huge. Thankfully it's not particularly memory hungry at least with small documents, but damn that's a big bundle for what it is. Why is it bundling ffmpeg? Does it really need GLES? Is a base Electron framework really >300MB?

- Options for a keymap, but after deleting the initial content I've lost the actual keymap! Would be great to have a help reference in the app, or at least a docs page on the website that the help menu links to.

- Would be great to be able to change the font.

- I don't understand the saving model. Where is the data saved? Can I control this? Is saving necessary? If not, how often is the data persisted? Can I put it in cloud storage so it syncs across machines, or if it does this already, can I opt-out of that?

- Not personally a fan of putting the name of the app in the icon. Most apps don't, I'd suggest something more subtle.

I don't think making someone a legend is the best way to celebrate an actual human being.

Leonardo da Vinci was human, he had flaws, he wasn't always right, and I think these are important things to point out in order to make the real achievements stand out.

Leonardo's flying machines were crap, which is to be expected when basic understanding of aerodynamics came hundreds of years after. Helicopters in particular are deceptively complex. And it would be a shame to put them on the same level as mechanisms he designed that actually worked.

I think it sets unreasonable expectations if you don't recognize the flaws of great men. And especially in science, being wrong happen, and it is not even a flaw.

>They are driving safer than humans.

I don’t think you can make this strong of a claim with the available data. Likewise, someone can’t make strong claim in the opposite direction. The best data I’ve seen is from NTSB investigations, and it clearly shows some very dangerous behavior. But it’s just a snapshot of data.

And I think you’ve taken away the wrong point. It was about unexpected behavior, not “driving with a death wish.”

The ability of people to consistently miss/twist the point to fit their own predetermined viewpoint is tiresome.

> Their demands and intentions are quite clear and solely focused on Israeli-bound ships...

Their actions haven't been, though.

https://en.wikipedia.org/wiki/Houthi_involvement_in_the_2023...

> On 12 December 2023, the Houthis launched an anti-ship cruise missile attack against the Norwegian commercial ship Strinda, an oil and chemical tanker operated by the J. Ludwig Mowinckels Rederi company, while it was close to the Bab-el-Mandeb. The Strinda was on its way from Malaysia to Italy (via the Suez Canal). The attack caused a fire aboard the ship; no crew members were injured. The ship was carrying cargo of palm oil. The French Armed Forces Ministry and U.S. Department of Defense reported that the Languedoc shot down a drone targeted at the Strinda, and the USS Mason also rendered aid. The Houthi attack on the Strinda was an expansion of its series of attacks against maritime shipping in the strait; the Houthis began to attack commercial vessels without any discernible tie to Israel.

Several more attacks since then, on ships with nothing to do with Israel.

Only when it comes to pushing BS content to children and hooking them.

When it comes to end-to-end encryption, they start to "think of the children" as it stops them from mining user communications.

So if Meta uncharacteristically appears to be pro-E2E-encryption here, it is for some ulterior motive (such as the "cover for litigation and to further distance itself from responsibility of how people use their site" you've mentioned), and not following their usual m.o. and profit motives.

Hi HN - I made texify to convert equations to markdown/LaTeX for my project marker [1] then realized it could be generally useful.

Texify converts equations and surrounding text to Markdown, with embedded LaTeX (MathJax compatible). You can either use a GUI to select equations (inline or block) from PDFs and images to convert, or use the CLI to batch convert images. It works on CPU, GPU, or MPS (Mac).

The closest open source comparisons are pix2tex and nougat - marker is much more accurate than both of them for this task. However, nougat is more for entire pages, and pix2tex is more for block equations (not inline equations and text).

I trained texify for 2 days on 4x A6000 GPUs - I was pleasantly surprised how far I could get with limited GPU resources by reframing the problem to use small parameter counts/images.

Texify is licensed for commercial use, with the weights under CC-BY-SA 4.0. Find them at [2] .

* Can I delete a block easily?

* After creating an additional cursor (great extra feature btw) how do I stop creating them, and/or remove one I've created?

In interpreting the number of “administrators” at different institutions, it is useful to have an understanding of when one is classified as an administrator. At my institution, there are basically three types of non-wage (classified) positions: tenure track faculty, research faculty, and administrative faculty. Librarians are administrative faculty, as, I suspect, are football coaches.

There are, of course, administrators among the administrative faculty, but far fewer than it appears.

As an addendum realize that these kids were making that awkward transition into pre and early teen years at the height of the COVID pandemic. Social media was a connection to their friends and peers that they did not see in most large social gatherings for at least 6 months if not closer to a year.

Now my kids have mostly transitioned into smaller group text chats and Facetime conference calls with their closest friends as they are getting older. They are also heavily involved in sports and other activities where they're invested in getting better versus the constant competition of social media.

I have also instituted an Apple-only devices in the house because while they do have their short comings, the Screen Time settings do work very well. I don't monitor my kids closely, but I do limit the amount of time they can spend on social media services, YouTube, etc.

Isn’t that a white-centric definition of what’s “normal?” Certainly, the high-stakes educational grind is normal among Asians in America, and middle class and up Asians in Asia too.
