Any algo/quant traders here? Is there a place for learning in public?
I've just started learning about algo trading. I want to publish some content about my journey as I don't have anyone to talk to in my personal network.

What's the best place to share this content and engage in conversations?

I've started a blog and shared my 1st post here, it got a few views but no comments. The relevant subreddits discourage sharing blog posts. I'm not sure if it's worth using X/Twitter, it looks like a place where you have to invest a lot of time so that you get to a stage where people talk to you.
Isn't SotA OCR done using CNNs? So it's AI even in the modern sense.
I'd also recommend installing Lulu https://objective-see.org/tools.html and blocking every network activity regardless of the version you're on.
Not according to the Judgment.

On 11 April 2017, Supermac filed an application for revocation with EUIPO in respect of the EU trade mark in respect of the word sign BIG MAC.
To be fair Apple Photos does this.

But it does it to your photos not your entire universe.
> I wonder if I could cause Recall not to work by just playing some DRM'd content half-transparent over whatever I was doing.

The hilarious part is that the feature - OpenRecall is already there so the feature is not going anywhere.

> This was already true and common.

Exactly plus removal of emails and history is something that courts are frown upon these days.
I love that DRM content was where they drew the line. Customer privacy? Eh, whatever. But movies? Let's not poke the bear...

Desktop copilots/assistants have huge potential, but this type of data collection can't possibly end well.
As it says in the paper, they already did the research with less limiting prompts. All models were tested with another prompt that gave only the question and no further instruction, and a third prompt that asked the model to consider its answer carefully.

The correct response rate chart doesn't even use the results from the concise prompt.
If a few people from a company you acquire can seemingly overthrow all principles and radically change the engineering culture, I'd offer that maybe the culture at Boeing wasn't all that strong in the first place. In any case, the acquisition of McDonnell-Douglas was 27 years ago. You can't keep blaming that forever.
Free publicity too.
(Edit: on the other hand, I guess with the legal bills it must have been pretty expensive)
That hides icons to the left of BTT, but BTT is already my leftmost icon. Do I need to change the startup order or something? Currently using HiddenBar which works great, but if I can use fewer apps, so much the better.

And thanks for BTT! It's in my "must-have" apps for any Mac along with Karabiner Elements.
I wouldn’t mind the total recall feature if it was OPTIONAL. I would probably use it on a dedicated pc that I would use for diagnostics and issue remediation on. Would serve as a (probably) great tool for creating documentation after the fact where you don’t have the bandwidth to do it in real time.

But to use it on a pc that is used for day to day activities? It would effectively circumvent every policy which I’m required to adhere to. This would be a shit show especially in government where anyone can legally and with force request “all correspondence and electronic records pertaining to xxx”.
Interesting. If you ask it to name the sisters it figures it out but then if you ask it why it changed its answer it reverts to the original. These things are clearly very good query engines but perhaps they fall short of reasoning.
Lot's of nice photos here.

The eminent Computer historian Janet Abbate's Recoding Gender: Women's Changing Participating in Computing (2012) is an history (and historiography) of women in computing. Highly recommended.

The average reliability rates cited (via US News rankings) explicitly exclude such major events. From the methodology page:

I don't know why you are getting downvoted. I was disappointed the paper didn't give examples of the LLM confidently expressing its incorrect reasoning.

From a human perspective, I think there are three ways to get the answer wrong: failure to realize that Alice's brother has pretty much the same number of sisters as Alice herself, failure to realize that the brother has one additional sister, namely Alice, and failure to successfully add one to the number of sisters. But that assumes that the LLM is more or less reasoning like a human. It may well be "reasoning" more along the lines of "I've seen lots of story problems like this, the modal answer was five, I'll say five"
There’s zero privacy with any ML/AI tools.
Is it possible it formed new inferences based on the analysis of the pervious models and their accuracy or errors? That would be the interesting part, but I'm not sure that was the case.
I think you are misreading the comment. Saying aside from those concerns does not dismiss the concerns themselves. It’s just expressing that this comment will speak about some other things, and not those things.
I had this confirmed during the Q&A portion of a demo presented by Microsoft. All the processing is supposed to happen locally using the NPU capacity of the hardware.
There is choosing the right tool for the job, and then there is evaluating the tools against each other on the properties specific to the job.

If after making your tool selection you went on to author a study about how gas cars result in more frequent bathroom breaks while driving, without controlling for the length of the trip, you’d be doing what these folks did, and that’s selection bias.
Some engineers complain about having the ability to pick their tasks and have input in prioritization and planning? This has always been the most attractive part of agile for me. Self-organized team. Built around motivated individuals. Striving for technical excellence.
No, they aren't. They're desperate.

We've realized for some time that not only are language model technologies going to dominate our future, but that they require massive compute to run. We've also been talking about Apple - their silence, but also their hardware capabilities to run LLMs on consumer devices. Every other player (OpenAI, Facebook, Microsoft, etc) is faced with a billion dollar datacenter investment that still provides a worse experience (latency & privacy).

Apple has a huge advantage because they get to pay nothing for a superior compute infrastructure that comes with a better privacy and latency story. As soon as they release something, it's going to be good, and it's going to be free, because it runs fast on consumer hardware and consumer electricity. A billion-dollar datacenter that's upgraded every N years can't compete with that. Microsoft knows this, and they're trying to get out in front of whatever Apple comes up with. That's why they're telling manufacturers to install these "NPU" things - it's a direct equivalent to the iPhone/iPad/Mac compute capabilities.

So no, Microsoft probably knew this would be the reaction. But it's better to get dragged through the mud for lack of trust than for being left behind the cutting edge. In the former case you're just a slimeball; in the latter case you're a moronic slimeball.
This looks like more of an "ad" (or a very directed study by a competing methodology), but excess pragmatism can ruin even the most sensible ideas.

Agile, testing, design patterns, best practices can all tank and bury a project if applied excessively "by the books" without consideration of the actual problem to solve.

I've worked in teams that had about 10 people actual doing dev work that implemented the full suite of Agile "principles" as rules. Daily standups, grooming, retros, pointing as "poker", 1:1s every week. The result was that we had barely time to actual work since the week had 10-20 hours of meetings. Most retros and standups were literally just us saying "same as yesterday, only had a few minutes to work on this" the whole week.

Testing is the same. If applied without consideration for the actual problems, reaching that 90%+ code coverage is easy if nobody cares about how hard and time consuming it will be to change code later. Specially when a feature is in very early development.

I think all those things are good, but what I see sometimes is that they are applied as absolute rules that cannot be deviated from, which inevitably leads to poor results.

I'm now working in a "light Agile" environment with just 2-3 meetings a week, barely 1 hour total, and much less strict PR/testing requirements (we focus on testing the important functionality, not line coverage count) and it is so much better. Some of the same co-workers that were under the more strict rules are now twice or more more productive then before.
Elon would also undoubtedly pour his Tesla money into SpaceX to keep it afloat. He's a lot more passionate about SpaceX than Tesla. But it's a moot point because SpaceX has a massively profitable monopoly on efficient space launches and probably will for a very long time.
I have an even simpler prompt for LLMs that run on mobile: "how many feet are in four feet"-- confabulations on this one sometimes revert to counting toes.
I experienced some unusual breakdowns too, playing with these prompts on gpt4o now. I'm wondering whether this might be caused by RLHF penalizing it for assuming Alice's gender.
Except it very obviously IS a medieval world. Not our Middle Ages, but a world that works very closely like how we understand Middle Ages to work. It's feudal, he understands Anglo-Saxon warfare to an amount surprising in an author of trivial literature, and he very obviously DID make a huge effort to make many details correct either in the "how we understand the past" way or to frame them in a way that is understandable for the people who read Beowulf and similar myths.
I find it weird because the criticism was not that Canada is bad, but that it's not exemplary in any way, as if that's a good reason to badmouth something. I don't find Slovenia exemplary in any way either, but that's not a good reason for me to badmouth it. Of course being perfect at everything is the ideal, but in practical terms, being mediocre (in the sense of being average) is... just fine? Just seems like a weird thing to say.

> with dick moves like disabling auto-save to local files in Microsoft Word (your autosave data only autosaves to OneDrive)

Unrelated, but this burned me so hard a few months back - I was so pissed. Worked on a document for hours, saved it but the file was corrupted. No problem, will restore an autosave snapshot... only it was disabled in some update, and only works with OneDrive if you manually toggle the switch. I was flabbergasted.
The classic example of this is Apple (a.k.a. Apple Corps and their subsidiaries Apple Films, Apple Records, Apple Studio etc) versus Apple Computer.

In this case, the original complaint was by McDonald's saying that customers would confused the "mac" in Supermac's with the Big Mac. Using your analogy it would like having a company called "Mouse House" that sells anthropomorphic mice characters.
Why do you think that digital copyright has poisoned society and needs to go?
I have observed that there are two kinds of Agile.

"Agile in doctrine" is the kind all of the anti-Agile crowd rail against because they've been burnt by working for some company or manager who drank the Koolaid without actually understanding what Agile is. Blindly following some consultant's Agile playbook is not Agile.

"Agile in spirit" is a bit like The Zen of Python: X is usually better than Y but there are times where it makes complete sense to do Y. In order for Agile to work, you need to have leaders and CIs who understand that. Agile emphasizes communication and flexibility. Agile is advisory, not prescriptive.

Nothing original to see here and nothing reformulated to be of practical importance other than a clickbait attempt. If this is your first trap of reading absurdist/populist LLM literature consider yourselves lucky. If you care about these models you know how powerful they can be and you probably learned how to use them. If you care and dont know how to use them, it helps to get some background on earlier language model research (maybe 2010–2018) instead to grasp the probabilistic underpinnings of causal inference and then some of the early OpenAI papers about GPT.

The manifesto describes an effect or desirable end state. Not a method.

Anything you do that fails to bring you this effect is your responsibility. Coaches are only agile insofar as they are helpful.

But this also mean you are free to learn from all possible sources, and you are not bound to any particular method or ritual.
For the number 2, I think one issue is that you are going to be semi-frequently whacking the db to do a mapping of that random string id back to the real id. OK for smaller entities but might be a pain if there's a lot of those ids to wrangle. You can throw a secondary index on it, but that will still have some minor fragmentation issues.

One benefit of a random id is if you are working with more complex data models it can make creating those easier/faster. Instead of having a centralized location to get new ids from (the DB) you can create ids on the fly from the application which can turn the write into a single action from the application rather than a dance of inserting the main table, getting the new id, then inserting to the normalized tables.
Microsoft is clearly not committing suicide: Look at how much attention this feature has got them. Every tech publication is talking about Windows. Windows is suddenly relevant again! How is that suicide?

It is Microsoft customers that is committing suicide, by leaving this feature on. Users need to be educated on the dangers of this feature, and how to turn the feature off.
Interesting UI slug. Truncation or word blacklist?
In general I've found Cloudflare dramatically easier to work with than AWS (as an individual dev, maybe not as a billing admin or whatever). Their services and APIs are a lot better thought out and documented, IMO, and their serverless stack in particular seems stronger than AWS's.

Just anecdotal though. I have no data to back this up and this isn't my area of expertise. Good luck!
I mean, people crap on Wall Street a lot for good reason, but honestly it's a reasonably well-regulated entity. It's not perfect, and you can find cases of utterly gross mismanagement (e.g. the 2008 crash), but stuff like insider trading and unregistered securities and the like do get attention from the SEC, particularly if they're reported.

I've said a lot of negative stuff in the past about the Wall Street banks, and I have come to regret most of it after learning a lot more about finance. Stocks absolutely can be a way for the "rich to get richer and the poor to get poorer", and of course the traditional exchanges aren't a vaccine against that, but I do think that they do some level of vetting to make sure that companies aren't just Ponzi schemes.

I mean, for example, WeWork had its IPO rejected in 2019 because regulators were afraid about its business model, and it only ever went public through a SPAC loophole. Clearly they shouldn't have gone public at all, but some basic sanity checking is better than zero.

To be clear, I'm totally onboard with Texas making their own exchange if they can actually do it better, or at least as-well. Competition is a good thing.

That's all kinds of wrong. A stand-up is supposed to take 15 minutes max, and if no one is stuck with anything, it shouldn't take more than just a couple of minutes. It's not supposed to be a "status meeting" at all.
> For some reason audiophiles will use darn massive gold (or silver) RCA connectors instead of something like a balanced connection that would actually make sense.

Is there a reason why they don't just use digital audio everywhere and convert to analog as late as possible? Inside the speakers for example? I mean, digital audio is pretty much perfect. Why are analog audio signals still a thing? People actually pay thousands of dollars for magical analog audio cables and it boggles my mind.
This used to be straightforward if you found your way into the internationalization formats and modified the right ones.

I'm neither smart nor a dev, but there is no need to feed the kid the internets data anymore, is there? The kid gets enough data fed to it by direct user input aaand that makes the kid preconfigured well enough to recognize and leave trash where it finds it, except if it can be up- or recycled but thats a long story.

Corporate data, research, books, blogs, any tokens the kid will train itself on will "feel" right in it's stomach and not "too heavy" or "too light" for its semantic mass. The rest of what the rest of the internet might have to offer in the future (comment sections) is so predictable, it would be a duplication of effort the next gen of AI won't waste any RAM on.
The interesting conclusion from this seems to be that the AI then could only get better when the underlying models improve, right?

So we'd still need to keep working on them anyway, or not?
My favourite feature in Apple and Google Photos. I use this all the time and have gotten so used to it I get annoyed when it doesn't find something.
Show HN: Writer Framework – open-source framework for creating AI applications
Writer Framework is an open-source framework for creating AI applications. Build user interfaces using a visual editor; write the backend code in Python.

Writer Framework is fast and flexible with a clean, easily-testable syntax. It provides separation of concerns between UI and business logic, enabling more complex applications.
It made it before at least one of its other launch attempts, IIRC.
They do replace the need for printing separate large-print editions, which is nice.
Have you bought a computer recently, or, like, ever? Every OEM pays a Windows tax, even on computers that don't come with Windows.
I'm afraid you've been reading too many sensationalist headlines. You are completely able to get a stable rate for power in Texas. No one is forced to choose a rate that can spike to $7/kWh.

In fact power in Texas is cheaper on average than many other places in the US (including NYC, where I live). This is partially because Texas is the energy center of the US, with abundant wind, solar, and oil/gas.

The Texas grid is the opposite of a third-world country. The engineering and operations groups at ERCOT are extremely competent, even if the PUCT sometimes forces them to make stupid decisions.
There may be a difference, but it seems you have them flipped. It is a reasonable assumption to think that they have controls to limit who is able to see information[1], but one must go in with the expectation that every acting agent has access.

[1] Of course, since you don't know who the individuals are, you still have to place your trust in every single agent that works for the entity you chose to entrust. As such, nothing is gained by restricting access. It remains that if it is important that it be private with only one or a few, you must go to those individuals you trust directly. Granting them private information by proxy will always be subject to man-in-the-middle-ing.
I really don't think installing software is an edge case. On Linux distros, I don't even think compiling software is an edge case.
It's called a history book, and the problem is that a lot of the people who yell about removing "red tape" have read those history books and want to do the things the red tape was literally created to prevent, which is usually lie to someone to make money, and then millions of Americans who think reading history books is woke get very very upset that they can't give their money to companies that need to change the law to be allowed to lie.

Look at crypto. That's literally a system with very little """red tape""" and it's nothing more than a breeding ground for fraudulent investments because the company that promises 10% but literally cannot deliver will always beat out the companies that promise 4% but can mostly safely deliver that. If there's no punishment for lying, honest companies are at a disadvantage, because a market is not a transparent system, you cannot know the internal workings of a company that isn't required to make that info public.
this is true. and the extreme amount of experience and tuning required to run these models is really not appreciated outside scientific computing

but you have to admit, they are really gross to work with
Latency at the Edge with Rust/WebAssembly and Postgres: Part 1
During our journey towards WebAssembly support for Exograph, we learned a few things to improve the latency of Rust-based programs targeting WebAssembly in Cloudflare Workers connecting to Postgres. This two-part series shares those learnings. In this first post, we will set up a simple Cloudflare Worker connecting to a Postgres database and get baseline latency measurements. In the next post, we will explore various ways to improve it.

Even though we experimented in the context of Exograph, the learnings should apply to anyone using WebAssembly in Cloudflare Workers (or other platforms that support WebAssembly) to connect to Postgres.
