I've been building algorithmic trading models for the last 4+ years. After trading them successfully with my own capital for more than a year, I launched https://grizzlybulls.com as an alternative to the traditional hedge fund monetization path.

Since launching in January 2022, we've significantly outperformed the market with lower volatility and reduced max drawdown:

Model - Return - Max drawdown

S&P 500 (benchmark): +9.91% -27.56%

Platinum: +45.34% -16.48%

Gold: +39.53% -19.12%

Silver: +17.24% -22.96%

Bronze: +14.12% -23.93%

Vix Basic: +9.81% -24.23%

TA - Mean Reversion: +17.77% -19.92%

TA - Trend: +17.29% -24.98%

This is an unleveraged, apples to apples comparison. These are not high frequency trading models. Most of them only make a trade every 2-4 weeks on average. During long signals, the models are simply long the S&P 500 and during short signals, they go to cash. This can be implemented very tax efficiently by holding a core ETF long position that never gets sold and then selling S&P 500 futures (ES or MES) of equal value to the ETFs against the long position. This way your account will accumulate unrealized capital gains indefinitely and you'll only pay tax on the net result of successful hedging. The cherry on top is that the S&P 500 futures are section 1256 contracts that are taxed at 60% long term / 40% short term capital gains rates regardless of the duration they are held.

The models use a variety of indicators, many of them custom built. Most important are various VIX metrics (absolute level, VIX futures curve shape/slope, divergences against S&P 500 price, etc), trend-following TA metrics (MACD, EMV, etc), mean-reversion TA metrics (Bollinger Bands, CMO, etc), macroeconomic (unemployment, housing starts, leading composite), and monetary policy (yield curve inversion, equity risk premium, dot plot, etc). They've been backtested very cautiously to avoid overfitting.

According to your link the ear mostly work in the frequency domain:

Once the vibrations cause the fluid inside the cochlea to ripple, a traveling wave forms along the basilar membrane. Hair cells—sensory cells sitting on top of the basilar membrane—ride the wave. Hair cells near the wide end of the snail-shaped cochlea detect higher-pitched sounds, such as an infant crying. Those closer to the center detect lower-pitched sounds, such as a large dog barking.

It's really far from PCM.

Today we are happy to annouce the v1.0.0 release of centerpiece !

What began as a small personal project with the goal to remove all bars in my desktop environment has transformed into a full featured application launcher with a variety of plugins. A special shoutout to @a-kenji who pushed the development along a great deal. This is the first of my personal projects to reach the 1.0 milestone!

Now, without further ado, enjoy this release and find us many bugs.

I don’t know Japanese and havent studied this so hopefully someone can correct me as well. But I dont think it would be right to translate this to the modern meaning of a ship pilot. It more loosely translated to “navigator”.

There are some seemingly good details here[0].

> In Early Modern Japanese there was a word 按針 anjin, literally “searching needle,” which referred to the process of using a compass. At the time, this was the main way in which ships were navigated and so, by extension, the word was applied not just to ship navigation, but also to ship navigators

It goes into more detail about things as well but that is the part that stuck out to me the most.

> ”Redundancy doesn't necessitate the redundant option being identical to the first.“

Yes. In fact, in a redundant system, using different designs or technology is often an advantage, so that a failure mode that affects one system is unlikely to affect the other.

But if something is redundant, it is “able to be omitted without loss of function”. Front and back brakes on a bike are not there for redundancy. They are components of the same braking system: without both in service, they don't work as well.

Or to put it another way, the front brake isn’t there as a spare in case the back brake fails. It’s there because without brakes on both wheels, you can’t stop quickly in an emergency.
Meta enabled ActivityPub based fediverse support this week for US Threads users.

So today you can spin up your own Mastodon server and have anyone follow you from Threads and vice versa.
One of these lovely discussions again. I’m firmly on the devil’s advocate side here: some install bloat isn’t a big deal.

1. Believe it or not the LinkedIn app is huge in terms of the amount of things it does. It’s basically a super-app for professionals. News, social interactions, an entire chat app, a job board, recruiting and sales tools, etc. Of course it relies on a lot of frameworks.

2. You don’t need a “high end” phone or expensive data plan to have this size of install be reasonable. A brand new $159 Samsung A03s phone can take a 1TB SD card which itself only costs $60 from a reputable brand. You can get an unlimited data plan for $30/month from Mint mobile. Basically, the poorest consumer in the US can “afford” to install the app. Mobile download speeds in the US are far into the double digit Mbps. I’ve seen speeds go up into the hundreds of Mbps. Of course the option exists to have your apps update over WiFi automatically and use no mobile data at all.

3. Install Size != Slow performance. Grand Theft Auto V is a 100GB install on my computer, but it runs at a buttery smooth framerate on modest hardware.

4. Those criticizing LinkedIn for having a large development team that has to rely on frameworks rather than custom-building tightly integrated functionality are just on another planet entirely. The app is optimized for ease of development, not install size or perfect performance. LinkedIn isn’t going to hire a bunch of expensive, impossible to find 10X developers just to over-optimize their app so that somebody will notice that it only consumed 50MB of space instead of 500.
That's actually how the meters currently work.

The article explains it a little better, but there's the meter equipment and there's communication equipment.

The communication modules currently installed might only support 2G (GSM) and 3G (UMTS) networks, but those could be replaced with new modules that support 4G (LTE) and/or 5G (NR) networks.

The meter itself doesn't need to change.

That is the plan for handling the closure of 2G and 3G networks.
This article got it all wrong. The management hierarchy is merely a proxy that reflects the real power structure in the organization. Even if you successfully eliminated engineering managers, there will always be an implicit hierarchy which is worse IMO. You're not supposed to pretend like there's no such structure; you need to reflect it transparently and put those with powers to the position accountable for the decision they made.

I remember an interview from a former Valve employee [1] who described the company culture as "high school". This precisely points out the problem lying under those manager-less structure. The exact quote was:

> "But the one thing I found out the hard way is that there is actually a hidden layer of powerful management structure in the company and it felt a lot like high school. There are popular kids that have acquired power in the company, then there's the trouble makers, and everyone in between."

Thanks! I'd say it depends a bit on your mother-tongue and general sense for languages, but yes, this is based on a very intuitive approach to language learning where you infer meaning from context, and even absolute beginners should be able to pick up some basic phrases.
I think the OP was saying that having minors agree to a social media sites terms and conditions is them entering a contract. So if you're against minors entering contracts, its logically consistent to also be against holding minors to a websites terms.

That's kind of on Instagram for forcing you to log in—I certainly never use the site to look at anything. Google maps certainly doesn't require this.

> - You're overdoing it with the shadows. Simple flat design looks cleaner

I'm not a designer, but I strongly disagree with this one. Given a choice between using something flat or something with shadows, I will almost invariably lean towards the latter. The one place I might eliminate shadows for on this site is the "info" callouts on each book page; I don't think shadows communicate anything there and all other shadowed boxes on the site are clickable, while this one is not.
> great product managers are leaders without authority

This is something that I really hadn't thought about before now. I used to work for a great product manager. He had a deep understanding of the problem space, expert-level knowledge of the technology we used and was an amazing customer advocate and pushed for us to always consider the customer first.

Unfortunately, as a human being, he was kind of a Type-A asshole. And he was also the CEO. That meant that right or wrong, he would usually get his way, even if it meant changing priorities 5 times in 3 days. To his credit, he realized that he had blind spots, and he would challenge us to push back against him. But realistically, how hard are people going to push back against the guy signing their paychecks?

Take away the authority he held as CEO, and I maintain that the company would have achieved far greater results.
This is the exact problem. It ails many very senior engineers - the circumstances have changed, but they continue on insisting it is still 2010 (in this particular case, closer to 2004). But hey, you were lucky enough for the problem to not cause significant issues, minor loss for the colleagues notwithstanding, good on you!
Currently working on a prototype "fuzzer" for react components, where the input is programmatic interaction with said component (clicks, typing, toggling), and the output is graphical representation of all possible states this component can get into. This is tracked through code execution, but ultimately displayed in DOM form.

There is actually a lot of work involved in tracking everything for an operation.

If an ai is able to record an operation with 9x% accuracy but you save humans, the insurance might just accept this.

Nonetheless the chance that ai will be able to continually become better and better at it, is very high.

Our society will switch. Instead of rewriting software or updating software we will fine-tune models and add more examples.

Because this is actually sustainable (you can reuse the old data) this will win at the end.

The only thing changing in the future is model architecture and training data will only be added.
Well, absolute zero temperatures (or close to it) are the usual way to create quantum computation. Absolute zero temperatures however are totally impractical economically also size of the machine (see MRI machines) and other reasons i cannot recall right now.

In absolute zero temperatures, the electrons behave in a discreet way, like digits, they behave less unpredictably. Temperature is one way to control their movement, but i think magnetism is another one.

What these two discoveries mean (MoTe2 and the graphene one), is that there is another way to control their movement, less unpredictable movement once again, in normal temperatures and without magnetism. They call that "fractional quantum anomalous Hall effect (FQAHE)".

That's my take on it. Still not GPT-4 level but getting there.

EDIT: Also 2d material means a material one atom thick. Graphene is exactly that, that's the definition of graphene: graphite one atom thick. The two materials they describe, are not 2D exactly, but they are thin enough that they consider them 2D. They essentially mean sheets of atoms, instead of them being just an atom thick, a little bit more, like 5 or 10 atoms thick.
It's hard to believe that you should not be able to open a file, edit and save it with GNU Emacs. I have a Mac, downloaded https://emacsformacosx.com , started it, command-o opens a file dialog, typed characters, command-s saved the file.

That one is an ancient code base dating back to the 60s, written in a Lisp dialect roughly ten people in the world can program with some competence (I can't, can you?). It's a nice project, but it is far far away from what GNU Emacs provides. GNU Emacs has many many thousand man years more work and polishing in it, ongoing.

If you would learn a complex and large Lisp like Interlisp or Common Lisp, then one would better use a development environment for it. I doubt Medley is easier to use&learn than something like GNU Emacs + Slime + SBCL. For Common Lisp, Medley is the worse development environment, since very few code has developed for and with it. People use other tools to write Lisp code (vim, GNU Emacs, ...). People are just trying to get Medley to somewhat support the state of Common Lisp from 34 years ago (CLtL2). It has, like, zero support for Scheme or other programming languages (Python, Java, JavaScript, C++, Rust, ...).

GNU Emacs is not my favorite Lisp IDE, but it's by far the most practical solution for average developers: it does not cost anything, it has good Lisp support for several Lisp dialects and all kinds of other programming languages, it runs good enough on almost all current operating systems, hopefully respects my data privacy, ...

Sure one can use a new editor with less support for Lisp. I've also known Lisp developers using vi in a terminal. People have different preferences for their tools.

It will be interesting for businesses like restaurants that don't have paper menus but have you scan a code that opens an IG with their menu in an album. Frankly, I applaud the state for eliminating this use case.
We don't have engineering managers at my job. works fairly well. we have managers that manage the HR aspects of the job and do some coordination of the work as far as placing people where the work needs to be done. but they are completely hands off on the technical side.

i am on whatsapp, wechat, telegram, matrix, signal, sms, irc, email, even discord...

on each of these services i am mostly in contact with real humans that i met in person.

i am in a few groups mostly made out of these same people, but also some groups where i never met anyone. i am not on facebook, mastodon or ex-twitter or any service that tries to feed me with stuff instead of just giving me a timeline of all messages shared. even on youtube i follow the channels of my choice and mostly ignore recommendations except to discover other interesting channels.

i don't see any of that going away. therefore i don't see anything changing for me
I made something like this pretty recently, though it was with an ESP32, and it was bluetooth, and I used a mouse driver. It was cool, though I did kind of grow a hatred for the Arduino "poll the pins in the loop" way of doing things. It would kind of work, but the problem would be that if you spun the knob too quickly, it would actually end up going backwards because you're effectively spinning faster than it can sync.

I ended up having to learn how to use the FreeRTOS interrupts. It was a bit harder but it was a much better play experience.

What heavy metals? Leaded fuels aren't used for decades. Diesel exhaust doesn't really leave anything worth caring about on the crops, "natural" pollution from rain, soil, bugs and birdshit is an order of magnitude more relevant than exhaust, and the things intentionally sprayed on fields - fertilizer, herbicides, pesticides - is much worse than those, even for organic farms manure and their range of approved pesticides are applied in huge quantities and will mean polluted crops that (obviously) need to be washed and will have all kinds of harmful residue anyway.

If the device was solar instead of diesel, that wouldn't move the needle on the dirtiness of the crops. Even the pollution from wear&tear on tires and brakes is more relevant than fuel - we worry about fossil fuels due to the global effect of greenhouse gas emissions, we also care about people breathing in small particles from diesel exhaust, but it doesn't really harm food in farms.

I can’t find any bridges which have a barrier that can protect against a fully loaded container ship. I have seen plenty of barriers which would protect against personal watercraft and smaller working ships like smaller tugs/coast guard ships/shrimping boats, etc.

But a loaded container ship at 8 knots is not going to be stopped by anything remotely feasible.

Container ships weigh between 50,000 and 220,000 tons. A US aircraft carrier weighs 100,000 tons.
> all the pollutants, heavy metals, and other chemicals that are in the X liter of diesel a farmer burns per yet, ends up on, and in the crops.

It's really not that much. A combine harvester uses about 15 gallons / hour of fuel and harvests ~450,000 pounds of corn per hour ie more than a lifetimes supply of food. Various other equipment gets used but it's all trivial in comparison to what's directly sprayed on crops.

Meanwhile your directly exposed to all the car fumes around you on a daily basis. Also, tulips aren't a food crop.

That's what bool.ToString() defaults to which I'm matching. As for the file API, it's a bit unfinished as I'm re-consolidating logic into U8File (OpenRead and ReadLines work acceptably, U8File.Read works too - U8Reader is in a more polished state), but the intention for the files is to detect and strip BOMs (it already does that in most[0] places[1]).

There is way more heavy lifting that the library does on the "data goes in" side of things because "data goes out" story in .NET is already in a good shape with everything accepting ReadOnlySpan<byte> and ReadOnlyMemory<byte> - zero-allocation interpolated UTF-8 output into streams, sockets, etc. is achieved through extension methods and should you want to write UTF-8 BOM, you can simply do so beforehand working with the corresponding API directly.

However, if you have a particular use case in mind that you're interested in or have trouble with - do let me know as I'd love to have more user feedback!

Not just dirt cheap, the turn around time to manufacture was significantly lower. Sony had an existing CD manufacturing business and could produce runs of discs in the span of a week or so, whereas cartridges typically took months. That was already a huge plus to publishers since it meant they could respond more quickly if a game happened to be a runaway success. With cartridges they could end up undershooting, and losing sales, or overshooting and end up with expensive, excess inventory.

Then to top it all off, Sony had much lower licensing fees! So publishers got “free” margin to boot. The Playstation was a sweet deal for publishers.
That's so cool, thank you for recommending it!

It might be Paul Halmos. In his "automathobiography", titled I Want to Be a Mathematician (Springer 1985), page 156: "In the late 1940's I began to act on one of my beliefs: to stay young, you have to change fields every five years". He goes on saying "I didn't first discover it and then act on it, but instead, noting that I did in fact seem to change directions every so often, I made a virtue out of a fact and formulated it as a piece of wisdom".

You need a "spec" just the same for a CSV: does it have headers, is there a consistent column ordering, etc. Control characters work the exact same as commas and newlines, but you don't have to worry about escaping them because (unless your data is binary or recursive) the control characters won't show up in the data!
