Hi, thanks for the reminder, I will add a License soon, most likely be GPL.

The basic agent chat is working, I mocked the example data for taking prototype screenshots. The in-chat UI widget is not fully working now, so that part is also mocked UI for now.

> Despite the fully-local-no-cloud pitch, I see @openai/ dependencies You can choose to use GPT, Claude API keys, or you can deploy local models like Qwen using Ollama so it will be 100% local. If you want fully local experience, just choose Ollama as model provider

Thanks for your reply!

To calculate market cap, you take the most recent trade and multiply it by the total number of coins/shares/etc that exist. Since the number of coins is decided by the coin's creator, all they need to do is sell a single coin for a single cent to get whatever market cap they want.

Furthermore, scammers often do "wash trades" where they set up two accounts and have one purchase from the other, for whatever price they feel like. So now they're making up both of the numbers that get multiplied to determine the market cap.

Often in physics the equations are already known or can be derived. However, taking a formula, generally a PDE, and solving it efficiently is the real trick. Also as you point out, formulating the equation in terms of core invariants you wish to hold, plays an important part.

Finding simplified easy to solve solutions and using them to estimate solutions and using adjustments to get closer to the real solution is a baselime technique. That's the core of the pertubative approach in physics which uses : https://en.wikipedia.org/wiki/Perturbation_theory#:~:text=Pe...

However, now it's possible to train AI models to learn much more complex approximations that allow them to run much quicker and more accurately. A prime example is DeepMinds AlphaFold, IMHO.

I haven't read up on the research to much, but I'd place firm bets that AI models will be critical in controlling any viable fusion technology.

I worry about my own liability sometimes as an engineer at a small company. So many businesses operate outside of regulated industries where PCI or HIPAA don't apply. For smaller organizations, security is just an engineering concern - not an organizational mandate. The product team is focused on the features, the PM is focused on the timeline, QA is focused on finding bugs, and it goes on and on, but rarely is there a voice of reason speaking about security. Engineers are expected to deliver tasks on the board and litte else. If the engineers can make the product secure without hurting the timeline, then great. If not, the engineers end up catching heat from the PM or whomever.

They'll say things like...

"Well, how long will that take?"

or, "What's really the risk of that happening?"

or, "We can secure it later, let's just get the MVP out to the customer now"

So, as an employee, I do what my employer asks of me. But, if somebody sues my employer because of some hack or data breach, am I going to be personally liable because I'm the only one who "should have known better"?

every endocrinologist i've ever had says you need at least some carbohydrates. that said, they're usually not nutritionists, and there's historically been so little focus on food as medicine within western medicine that i think we "officially" know as much about that as we do about diabetes at all (which is a lot, but still surprisingly little).

there are plenty of good reasons we eat carbs (especially complex carbs, plus trying to avoid processed stuff); as a diabetic you just have to prepare ahead of time. it sucks, but honestly, as a 20+ year T1D, not eating cake sucks more than having to plan to eat cake :)

I definitely agree with you, and apologies if that didn't come through in the piece! (Perhaps the rare case where I undershot on the metaphors?)

One thing I didn't mention but certainly believe: academics were attracted to USENIX ATC because of its attendance count (especially at the height of the Dot Com boom when it had nearly 2,000 attendees!) -- but no one really took apart who was attending or what they were looking for. So the conference became more academic because of the attendee count -- but that it became more academic also drove the attendee count down. (I heard from a lot of practitioners who attended that they struggled to find sessions that were relevant to their work in even the broadest sense.) I know I link to it in the piece, but I think Rik Farrow's piece[0] really got right to the heart of all of this.

I don't feel like I have a good understanding of all the context but I don't think that's the implication at all. The post does offhandedly mention that doing online only conferences get "more bang for the buck" but the rest of the post and linked articles and talks discuss other aspects and, in my opinion, mirror your last sentiment about it happening to all conferences and journals.

For example, one of the linked talks from 2016 "A Wardrobe for the Emperor" [0] talks about adding a more social website features (stars, likes, comments, feedback, etc.) to arXiv to improve it. He also talks about the "Papers we love" meetups, which are in person.

I think the Usenix ATC is a highlighting a deeper problem and that it is happening across other conferences, journals and disciplines. I don't have a good theory of why. I think Cantrill's observations are part of the puzzle but I don't have a good sense for why things changed so drastically (and I think they have, compared to 20-40 years ago).

I would like to see laws that make storing PII as dangerous as storing nuclear waste. Leaks should result in near-certain bankruptcy for the company and legal jeopardy for the people responsible.

That’s the best way I can think of to align incentives correctly. Right now there’s very little downside to storing as much user information as possible. Data breach? Just tweet an apology and keep going.

> One note about the framing. The average US Driver excludes everyone who isn't a driver

That's true but traveling by car is so overwhelmingly common that it doesn't swing the stats much. Only about 3% of people travel by public transit (most of which is a bus on the road anyway) and another 3% under their own power, with most of that being people who walk (mostly those who work/live in the same place).

You're shouting into the void. The people making this type of product have zero regard for their users' data, and best engineering or security practices. They're using AI to pump out a product as quickly as possible, and if it doesn't work (i.e. makes them money), they'll do it again with something else.

This can only be solved by regulation.

> You may well actually be prediabetic though, it just depends on the specific numbers for A1C/average & peaks combined over time and not the presence of a response itself.

Just to clarify - A1C is itself an easily-measured proxy for diabetes mellitus, but it's itself a heuristic. There are groups for whom it is known that the "standard" A1C range is actually incorrect, because of confounding factors that affect the A1C measurement but are unrelated to the metabolic dysfunction or general sugar levels.

Your point is correct, though, that what OP is describing is consistent with diabetes, and the actual clinical recommendations for prediabetes and Type II diabetes are often the same, at least in the early stages.

> You could caricature libertarianism, or you could engage with understanding what it actually is, whether or not you choose to agree with it.

Why is it that 99% of people arguing for libertarianism do a much better job making a caricature of it than anyone else that's intentionally tried?

I've tried to engage with them in good faith but ultimately all their arguments devolve into abolishing taxes and keeping track of existing bureaucracy on an individual level. Every. Single. Time.

It's not a practically tenable position. It's a youthful fantasy on the opposite side of the spectrum of property rights (the other side of the spectrum is communism).

Paper as in money? I can point to how multiple of these have saved me money directly. Cash dollars. Overdraft savings alone have numbered in billions back in the consumers' pockets... and that's just one piece of legislation that is easy to measure.

A lot of people don't realize how many current credit card regulations didn't exist 20 years ago. For example: you'd have to manually figure out how much interest was costing you and now they have to print it right on the statements.

They've helped rein in some of the most predatory industries out there in numerous ways.

In my experience, OsmAnd is mostly slow for very long routes.

Maybe it is a matter of quality. Because of course you can find routes fast if they are not the fastest or best routes.

But there is room for improvement. brouter could be integrated even better. Or a router like that could be used directly in OsmAnd.

And long routes could be handled more flexible. E.g., when I go from Copenhagen to Barcelona, it is not super important at first to find the optimal way into Barcelona, or shortcuts in France using regional roads. It will take several days, but I would like to start with a reasonable route giving me an estimate of distance and time. At first I just need a good route to the Great Belt Bridge or the Rødby ferry -- Copenhagen is on an island.

When I drive long distances, I sometimes use several devices. The Xzent system is much faster for longer distances, but the map is not as good, especially it is missing may POI's.

Often they disagree, especially if one is optimizing for distance and other for fuel or time. Then if there is an obstacle or a bad road, I instantly have a good alternative at an intersection.

Surprised they never mentioned jina.ai models such as jina-embeddings-v3 at 8K context and outperforming most "contenders" in the MTEB or jina-clip-v2 (multimodal) or "late chunking," also known as mean pooling: https://jina.ai/news/late-chunking-in-long-context-embedding...

It is very likely illegal but also discouraged to be prosecuted. From the federal government's guidelines on prosecuting unauthorized computer access (https://www.justice.gov/jm/jm-9-48000-computer-fraud):

> "The attorney for the government should decline prosecution if available evidence shows the defendant’s conduct consisted of, and the defendant intended, good-faith security research."

Yeah, the ethics around _training_ models that generate embeddings is still suspect to me, but the use of embeddings as a cheap, efficient way to provide semantic similarity seems very valuable. I've started dipping my toes in doing real, honest-to-goodness "machine learning" at work and it's mostly involved having OpenAI create embeddings for support logs my team generates, and we're starting to get value out of being able to cluster certain types of issues together, which I'm excited by. But this kind of stuff is truly augmentative: representing complex ideas in easily-searchable vector spaces, making connections in datasets too vast for humans to comb through alone, that's actual value.

> Government sources called the strikes “hell fire,” citing significant damage to Pakistan’s air power. According to estimates shared by Air Marshal Bharti, nearly 20% of Pakistan’s Air Force infrastructure was degraded.

> Ammunition depots were also targeted, and key Pakistani assets such as F-16s and JF-17 fighter jets were destroyed. Among the casualties was Squadron Leader Usman Yousuf of the Pakistan Air Force.

Wait, this is describing serious, bare-knuckled war, not a border skirmish that got a little out of control. So either the article is just fantasy or ... um ... somehow, no mainstream media outlet in the West has reported on the terrible, bloody war between India and Pakistan?

This is incorrect, though I don't blame OP as apparently it was being miscommunicated a lot on Twitter. Evergreen Intel on BlueSky says this is actually a Pakistani plane that was sold to them from the US some years ago. But many databases are out of date:

Somewhat downplaying it. Charles is easily the most popular tool for reverse engineering client-server communications in mobile apps.

Certificate pinning frustrates Charles by hampering MITM attempts. It can be difficult to extract/replace pinned certificates from the latest versions of Android/iOS apps. Often you can extract them from older versions using specialized tools, if old-enough versions exist and those certificates are still valid for API endpoints of interest.

My perception is that consumer protections are much weaker in the U.S. than in the E.U. It would be interesting if anyone has made any attempt at quantifying this.

We all know that there are other countries where far, far worse abuses of power take place, but I've wondered if the U.S. might be at some really unfortunate nexus of strong contract law enforcement + particularly poor consumer protections that leads to these particularly madding subscription cancellation-type services discussed in this thread.

I think this might be because once you have a tool, you either use it forever or until it breaks, and don't sell it in a good enough condition that it would be worth anything. My dad's circular saw, which he found in the trash 40 years ago, will probably last the rest of his life and all of my life.

Used tools are dirty, oily, and heavy. That's why my shop is outfitted with a lot of estate sale finds. Old people croak, and their next of kin don't want to move a half ton of steel (even to the thrift shop, who also doesn't want to move them around their store), so it ends up in the hands of people like me for near scrap prices.

Thanks and I apologize in advance for imposing on you.

A few months ago, I posted SaaSCurate here as an alternative to Product Hunt and other upvote-driven launch sites.

I built it because my experience with PH sucked: bots, hype, and no real support for early indie projects. I wanted to build something better.

But after some great feedback, I realized that just listing your product isn’t enough to drive meaningful traffic.

People would submit their product once and never return. There was no community, it just turned into another directory.

So I redesigned the platform, removed free tool submissions, and focused on something more valuable:

• Founders sharing lessons and experiences

• Getting discovered by actively contributing to the community

The idea now is simple: show up, engage, and get visibility through actual contribution – not just by listing your product.

Check it out here: https://saascurate.com/

I’d love to hear what you think, and if you’re building something, drop by and post. I want this to be a real community, not another “submit-and-forget” platform.

Yeah, I guess there's no reason for the API to ever return the OTP, but the severity depends on how you call the API. If the API is `api.cercadating.com/otp/<unpredictable-40-character-token>`, then that's not so bad. If it's `api.cercadating.com/otp/<guessable four-digit number>` that's a different story.

From context, I assume it's closer to the latter, but it would have been helpful for the author to explain it a bit better.

Posting the same link 4 times in 18 days, by the author, certainly seems like self-promo, but somehow allowed? I don't see any URL manipulation, and it certainly took off today. (I found it interesting!)

A&B testing of post names seems to lead some useful information ;)

I don't see your reference to "Georgetown students..." in either the website link or the user's submissions? Was it modified?

If I were ever a hiring manager, hell would have frozen over. But I'm not one for immediately firing someone for making mistakes. Correct the mistake and move on. Some mistakes will never be forgotten, and that dev will forever remember that somethings need extra attention.

Also, if we're talking about a company that had a hiring manager in the process of making an app and did not hire employees with security knowledge somewhere in the process, then the entire company is rotten.

Let me flip this on its head though with your same logic. If you're the type of person that would be willing to provide an app your passport information. Stop. Using. Apps.

Both Intellect-2 and zero data reasoning work on LLMs ("Zero data reasoning" is quite a misleading name of a method. It's not very ground-breaking.) If you wanna see a major leap in LLMS, you should check out what InceptionLabs did recently to speed up inference by 16x using a diffusion model. (https://www.inceptionlabs.ai/)

Our algorithms for time-series reinforcement learning are abysmal compared to inference models. Despite the explosion of the AI field, robotics and self-driving are stuck without much progress.

I think this method has potential, but someone else needs to boil it down a bit and change the terminology because, despite the effort, this is not an easily digested article.

We're also nowhere close to getting these models to behave properly. The larger the model we make, the more likely it is to find loopholes in our reward functions. This holds us back from useful AI in a lot of domains.

I am waiting for a new type of LLM that can understand primitives in either 2D or 3D and can construct vector art or 3D models.

I have seen some demos of Claude being connected to Blender etc. But when I dug into the code, it was using another LLM to generate the objects rather than building the objects from fundamental shapes.

The Linux audio stack is just baffling. After all these years it's still unreliable. I'm running Fedora 41 and often toggle between two audio devices, USB DAC and HDMI output. Sometimes when I change the output via Gnome settings my Flatpak apps don't care and keep playing with the previous output and other apps change as expected.

I've never edited any audio configs on this machine because I expected my 2 device setup and Gnome settings would be trivial enough for the latest Linux desktop audio solution.

What forced hand? America imposed tariffs, China retaliated. America insulted China and the said they want China to offer deal, China said they won't offer anything until America lowers tariffs.

America lowered tariffs and China responded by lowering tariffs too. They are both still very high, just not insane hard.

What exact strong hand are you talking about?

TBH, Uber wouldn't be so much of a problem with decent competition. But the critical mass required for a transit app is quite difficult to establish, and Lyft offers essentially the same deal with a slightly better margin for drivers. It's a de-facto duopoly here in the US where the two companies are incentivized to drive prices as high as the market will sustain, and the local apps (for instance we have one here in DC that is a co-op) are often legislated out of existence.

> Taxis in Shanghai have been largely replaced by app-related taxis.

The APP itself isn't the issue, it's the pricing. But it sounds like China has a much healthier market than we have.

> 1. It's now possible to get a taxi when it's raining.

Why would this make so much of a difference? I'm very curious.
