Nowadays, students often use apps to snap photos and quickly get answers to math problems, which is incredibly convenient. However, these tools often require registration and payment, with fewer options available for web-based platforms. That's why we've developed a [free, no-login-required] online AI math problem-solving website to meet the mathematical learning needs of students and parents on the web.
Our website not only swiftly solves various math problems but also presents the solution steps clearly, helping students better understand and digest the knowledge.
Come and try our website: [https://ai-math.top/] welcome to give us feedback~~~
P.S. The current version only supports text-based input of math problems, with future versions planned to support image upload for problem-solving.

Not knowing anything about this my first thought was what the hell did they spend that investment on to justify it in the first place? Were they just in a user acquisition war with draft kings and spending a ton on ads?

"Cybernetics" has an actual meaning distinct from anything to do with the Internet, and precedes it by decades. It is about using feedback from sensors to control something. It was based on observations of biological control systems, and creating principles from them for machines. For example using a gyroscope reading in a PID-loop that runs motors to keep a robot steady. The word comes from "Kuber" in Greek, which means "to steer".

The Internet-connotation comes from the "Cyberspace" in William Gibson's novel "Neuromancer", where it was supposed to be jacked into the brain: thereby the connection to biological control systems, and thus cybernetics.

I personally cringe at most modern uses of "cyber-". The only I don't to is "cyberpunk", which refers to environments and aesthetics as in novels such as Neuromancer.
I think this is more of a social problem with C++. Regardless whether the feature is implemented in the standard library or the core language, the broader C++ community is not going to approve of enabling bounds checks on the bracket operator. And whether this operator is implemented as a builtin or as an overload on an stdlib type is basically transparent to the user.

FWIW you can enable bounds checks for the bracket operator by default for STL types in GCC and Clang. So for interfacing with Rust it is both obvious how to translate between slices in Rust and std::span in C++, and you can verify to a degree that this std::span isn’t corrupted on C++ side (to a degree).

Show HN: Update dynamic IP in Cloudflare with bash
Hi hackers,

I made a simple bash tool to update 'A' records in Cloudflare for users with dynamic IPs.

I wanted to have a tool to keep a couple of DNS updated with my homelab dynamic IP so I wrote this very simple bash script.

There are tools that already solve this dynamic IP issue, but I find the simplicity of a bash script way more convenient than any tool that needs installation, complex configuration, a Python runtime or whatnot. This will basically run in any system with bash.

It is very simple and only updates A records, but it does its job and it solves my needs. It could be improved with more record types I guess, at least AAAA.
Sorting your data before searching it will only pay off if you need to search multiple things. If instead you need to search for one specific thing then going through things linearly is O(n) while sorting and searching the sorted result will be O(n log(n)).

It's not just about seeing people. It's about having deep connections and shared experiences. Eg: one of his friends has a life crisis and just needs to talk to someone. Are they going to hop on a train and track this guy down, or will they go see one of their other friends? So he will miss out being the person someone turns to, and these are the defining moments for long lasting friendships. Again, probably fine for a while, but if it goes on too long those existing friendships could fade away and he could miss out.

> The Hobbit was recorded at 48fps, not 60.

True, but it doesn't really change the point.

TLDR; gamers hating motion blur are not hating motion blur. They hate the way its implemented. It's far from the real thing.

The actual misunderstand here is that you are comparing apples to oranges. Motion blur for games is just as good and well-placed as it is for movies.

But only if it is actual true 3D motion blur that mirrors what happens in the real world (as in the parent article of this discussion).

In practice almost all games only blur the camera which blurs everything which leads to gamers then complaining about motion blur (and some even getting motion sickness/headaches).

Simple example: an object moves left accross the frame and the player tracks it while they're strafing fast to the right. Real motion blur means the object has almost zero blur since the player is tracking it (keeping it approx. in his FOV's center) while the BG is heavily blurred because of the strafing move the player is making.

When you only have camera blur, everything, including the tracked object is heavily blurred. That's what most games do and what gamers rightfully hate. But it is not the motion blur you see in film. Some games seem to do better now, I think this is called 'per pixel motion blur' in the games context (but I may be wrong).

> Exactly. The game has no idea what is and isn't moving in my FoV because it doesn't know what I'm looking at [...]

That is valid point if you had true motion blur and wanted to make this even better in a gaming context. See above.

I used to own and play around the FOVE VR headset (their SDK was absolutely terrible at the time and Windows-only, unfortunately, I sold it to a uni eventually) [1].

It had eye tracking. And that is indeed what you'd need to do the motion blur "better" for games where a player tracks fast moving objects accross the frame. Because you will have a slight discrepancy between the tracking of the eyes and the tracking of the look-at direction from motor latency and under-/overshoot.

I.e. calculate the difference in movement of eyes against final transform of geometry (including camera) to calculate how much motion blur you actually need.

For lack of eye-tracking hardware: I wonder if the game could guess what you're looking at and compensate the look-at vector with that to simulate fake eye tracking and get motion blur that is better received by some people.

That is the theory. In practice most games just do the "motion blur" wrong for starters. See above.

This is only tangentally related to this discussion, but this youtube video about science communication (through the lens of 'what killed the dinosaurs?') I found quite interesting: https://www.youtube.com/watch?v=6DHgkMYgp7w . Science communication is hard, and it's not that unusual for scientists to market their ideas to the public, but it's still difficult even then for the public to get a good idea of the academic view.
Basic jist of an exchange I had yesterday:

"Healthcare, infrastructure, K12 education and other essential services are a mess because we lack the talented resources to solve those fundamental problems"

"We largely do have the resources, it's just that they're all trying to get people to click ads, getting people to waste time endless scrolling on Reddit or Twitter or Instagram, managing their brands' social media accounts, etc."

This is not a problem in need of a solution. You both seem like really talented guys, and it's depressing that this is what you've decided will help make the world a better place.

That you're part of the YC24 cohort says a lot about what's wrong with the tech industry's priorities right now
Printing didn't require a lot of power. The Romans didn't have the precision (though arguably could have acquired that skill) to build decent steam engines, but more importantly they had no use for that power.

Delegating first-level bug triage to the community can also work as long as your company is well liked enough to motivate volunteers. For that you just need a public bug tracker that everyone can post to but only allow regular users (e.g. those who have made useful bug reports before) to confirm something is a not yet known bug and forward it to your developers. This way once you do get notified of a real bug you will have access to not just that one report but also potential duplicates that might provide interesting information - which might have never been filed if the first level was too high friction.
> people need people

While this lifestyle is not for me, i tend to concur on the statement. I personally pick my houses as distant from people as possible. People don’t need people. Sure it gets lonely sometimes but let me ask you if you enjoying the company you have all the time.

People don’t need people. It’s rather personality related
It may depend on the car.

In my car, I basically never change the A/C. My dad used to have a same-vintage car for a while, but a different make, and it absolutely needed adjustment depending on whether the sun was shining on you or not, and possibly other parameters. They both had "automatic" A/C.

Now these cars are ~20 years old, maybe things have improved. I haven't ridden in my dad's ~2yo car for any long stretch during the summer to compare.

The freedom to decide one day to just leave.

In my mid 20s I maintained a not-too-extreme minimalistic life style where I could pack literally everything I owned into my car. I could decide to just leave and lose at most some months' worth of rather cheap rent.

I never actually did use the opportunity, but it gave me a lot of comfort knowing that I wasn't stuck somewhere, that I could at any moment just leave.

> tools useful for music creation ... sort of Blender for sound

This is a very wide range of tools. Music can be represented and created in various forms. An established and widespread method is the presentation and processing of music in the form of individual events, organized in tracks and chronological sections. Famous commercial "computer aided design" tools for this approach are, for example, Logic Pro from Apple or Cubase from Steinberg. There are many open source alternatives; a useful list is e.g. here: https://alternativeto.net/software/logic-pro/?license=openso...

But music can also be represented and composed in the form of program code, usind a special programming language, for example. Here is a good overview of available (open source) solutions: https://en.wikipedia.org/wiki/List_of_audio_programming_lang...

Considering that heat pumps have a coefficient of performance of greater than 1 (meaning they are moving more than 2.6 kw of heat), no. You'd probably need 3 to 5 GPUs to get comparable levels of warmth.

Not really, because Concorde died in the seventies when the lie flat business seat didn't exist.

BA and AF managed to keep the zombie fleet going very profitably all the way until the end in the early 2000s, and that business wasn't killed by the lie flat business class seat either. It was killed by the impossibility of continuing to operate a tiny fleet of '60s planes forever.

Now if you said that the reason we don't have ANY supersonic passenger jets today is because lie flat business seats are good enough, then that's a more defendable position, but I'd still say that the overland flight restrictions limiting any SST to just a couple of routes is a bigger factor.

When I flew on Concorde the one thought I never had was "I wish I had a lie flat seat and half the airspeed".

It's set up as 3 separate displays, from left to right: 4K30 (you can also notice compression in color saturation), 4K60 (main monitor), built-in display. Even at 30Hz, the second 4K monitor is good for keeping up documentation.
Seems like fair compromise.

Truth be told I realise that this is a case where whatever you do, there will be consequences. I myself I don't really know how I'd approach that.
"Except we're talking about 100% and 200% interest rates, if you read the article."

I did read the article. I even went back a looked again. I see no mention of interest rate for the FanDuel deal.

"company financing $333M"

So if you're saying they financed this amount, there's no way they're subject to 100% interest if the investors get up to approximately $550M. Not to mention this investment timeframe covers years. I don't have the timeframe. What was the actual rate of return? I'm guessing low to mid single digits. Why would an investor put money into something so high risk for so little money when they could just put it in safer assets with higher return?

It sounds like you're angry they got nothing because you're only looking at it from the founder perspective. They agreed to the terms.

Both traditional desktop and laptop markets have been declining or flat (respectively), and both are anticipated to decline in near future years, if not already. See e.g., <https://convergetechmedia.com/laptop-sales-vs-desktop-pc-sal...> for overall markets and <https://www.cnn.com/2024/02/29/business/dell-earnings-ai-ser...> concerning Dell's recent performance.

To the extent that Linux has always represented an advanced technical subset of the market, the desktop market is effectively shifting further to technical users. "Casuals" increasingly rely on mobile devices --- smartphones and tablets, possibly netbooks. Technical users who are already more likely to choose Linux (or similar alternatives such as the *BSDs) are increasingly concentrated in the desktop market.

I'll note that I'm not one to lump Android in with Linux, as the overwhelmingly prominent Android UX does not include Linux applications or environments, even if those are in theory available (e.g., through Termux).

Whether or not overall Linux usage is increasing, as in total interactive users and time-in-OS (that is, for those using multiple environments, including virtualised environments, what is the split of time between OSes), and the value associated with usage (especially in professional / commercial contexts) isn't clear from the Linuxiac article. I suspect that there's some absolute growth as computer markets grow modestly overall, but that it's less significant than the percentage of desktop top-line figures would suggest.

(Written as a Linux user for well over a quarter century, and an Android user for a decade and a half, along with numerous other platforms.)

Is this train thing really different from the average "digital nomad"?

They too are away from their old standing friends, and since they are usually not intending to stay forever in the country they stay in, they're probably not investing in any deep connections there either.

In fact, given the huge loneliness/isolation trends, he is probably not that different to the average stationary person in this regard either.

>> Because they take on significant risks, investors expect to get “VIP” head-of-line privileges to be paid upon a liquidation event such as an acquisition.

What a crock of shit. I understand that employees might be considered "lower risk" because they get a paycheck.

I have the 2022 X1 Yoga Gen 6 as well. I am not impressed by battery life. Watching a 4K movie can easily drain the battery form full charge.

The major issue is over heating. Unless I place some small item underneath it (think a lighter size) to make a 1 inch gab between the surface and the laptop it overheats to the point where it stops functions (e.g. movies starts to freeze up). With a bit a airflow underneath it this problem goes away. The casing can get really hot. Almost to the point where you burn yourself. Almost.
I charge it overnight and usually leave it unplugged for the day. It's rare for the laptop to give out before I do. T14s gen 1.
