Any course is functionally useless if you don’t do the work, and my comment was not about people having to take forced courses. It was about people being naive, and willfully so, about the practical value of these courses and then making factually incorrect statements about them being useless for the area of study where they want to make a career. It is identical, only with different subject areas, to a computer science student saying that analytical algebra is useless and has no value. I think most readers in these spaces would see that and say “huh? maybe you’re never going to be working on a CAS system or some other application of it but do you really not comprehend the basic idea, you’re not understanding that there’s direct practical utility in your future career in training yourself to be capable of thinking in those ways?”

It is a failure of factual understanding in how cognitive function and critical thinking arises from the brain. If a person isn’t going to do the work then by all means don’t waste their time, but don’t indulge their factually incorrect stance that it has no utility simply because they also don’t have the basic knowledge to know what that utility is.

Thanks for the thoughtful analysis. I want to address the one-time pad comparison specifically, as this is a common misconception. ZOSCII is fundamentally different from a one-time pad: A one-time pad has a 1-to-1 relationship:

Each plaintext bit maps to exactly ONE ciphertext bit (via XOR with pad) Given the pad, there's exactly ONE decryption Security comes from the pad being unknown

ZOSCII has a many-to-many relationship:

Each plaintext byte can be encoded as ANY of ~256 different addresses (wherever that byte value appears in the LUT) The same message can generate 256^(message_length) different address sequences For a 10-byte message, that's approximately 1.2 × 10^24 different valid encodings of the identical plaintext

This creates exponential, not linear, ambiguity. With a 64KB LUT (65,536 addresses), you're working in a much larger combinatorial space than "256 pads" - you're selecting from 65,536 possible addresses with ~256 valid choices per byte.

Regarding practical implementation on 8-bit systems: You don't need 64KB - that's just a practical good size. A 16KB LUT still provides millions of combinations and achieves 100% information-theoretic security. The LUT size is flexible based on your constraints. For encoding sizes:

16-bit encodings: 2x original data size 32-bit encodings: 4x original data size 64-bit encodings: 8x original data size

Without preprocessing, an 8-bit computer only needs to hold the LUT itself in memory (16KB, 64KB, etc.). With preprocessing for faster two-way lookups, you need approximately 2.1x the LUT size plus the original table - but this enables near-instant encoding/decoding.

The security model is entirely different:

OTP security: "You can't determine the plaintext without the pad" ZOSCII security: "Even with a candidate LUT, you cannot prove which of many valid plaintexts is the original"

This provides plausible deniability that OTP cannot achieve. The same address list could decode to "ATTACK TOMORROW" or "HELLO MOTHER" depending on which LUT you use - and there's no mathematical way to prove which interpretation is correct.

Regarding your point about mathematical encryption with comparable key sizes - yes, traditional crypto is more efficient. But ZOSCII isn't competing on efficiency; it's providing fundamentally different security properties: undetectable encoding with perfect deniability. The encoded output is indistinguishable from random data or any other legitimate data format.

I recently set up infrastructure where all VPC communication is happening over IPv6. The only part that doesn’t is IPv4 communication with Docker but that’s because Docker + Kamal doesn’t have good support for it yet but work is very much ongoing for it. IPv4 was set up along side it but is not actually used. This took maybe minutes, if that, of additional effort. It runs a mature production project. And like chances are you are smarter than me so what exactly is your excuse?

> Having solidarity with the Chinese people is unrelated to criticizing their government.

It’s not unrelated because the NIST demonization of China as a nation contributes to hostilities which have real impacts on the people of the US and China, not simply the governments.

> The idea that one should first criticize their own government before another is the whataboutism.

Again, that’s not my position. You present me as countering criticism by pointing at US faults. But I acknowledge the criticism. My point is that both have faults, both governments deserve our suspicions, and our actions, practically speaking, should be first directed at the dictators at home.

As for the supposed national security concerns - all LLMs are insecure and weaker ones are more susceptible to prompt injection attacks. The paper argues that DeepSeek is a weaker model and more susceptible to these attacks. But if it’s a weaker model isn’t that to be expected? The report conflates this with a national security concern, but this insecurity is a characteristic of this class of software. This is pure propaganda. It’s even more insecure compared to the extremely insecure American models? Is that what passes for national security concerns these days?

Secondly the report documents how model shows bias, for example censoring discussion of Tiananmen Square. Yet that’s hardly a national security concern. Censorship in a foreign model is a national security concern? Again, calling this a national security concern is pure propaganda. And that’s why it’s accurately labeled as Sinophobia. It is not concerned about national security except insofar as it aims to incite hostilities.

What our government should be doing internationally is trying to de-escalate hostility but since Obama it has been moving further in the opposite direction. With Trump this has only intensified. Goading foreign countries and manufacturing enemies serves the defense lobby in the one hand and the chauvanist oligarchs on the other. Really, it serves the opposite of national security.

> Also, the pay is ok, but honestly it's not going to be as high as in VC-backed employers.

This, for me, has always been the deal breaker in moving out of VC-funded tech. Leaving corporate tech jobs is already a big enough hit to TC. Getting out of VC-funded tech very often means a dramatic change in life style. The VC world might be insane, but so is the comp.

It's not just the money. The biggest thing I've notice in my career is that, as a general rule, employers value you (or any resource for that matter) in proportion to how much they pay for you. Often people have the illusion that getting paid $80k a year when you used to make $300k will mean that your employer will recognize that you are a tremendous value. They won't. they'll see you and treat you as a low tier worker that can easily be replaced, has timed breaks and 30 minutes for lunch.

How's the vertical integration going for IBM? Kodak? Anybody remember the time Verizon bought Yahoo? AOL Time Warner?

Everybody thinks they can be Apple without doing any of the things Apple did to make it work.

Here's the hint. Windows and macOS will both run in a virtual machine, which abstracts away the hardware. It doesn't know if it's running on a Macbook or a Qualcomm tablet or an Intel server. And then regardless of the hardware, the Windows VM will have all kinds of Windows problems that the macOS VM doesn't. Likewise, if you run a Windows or Linux VM on Apple Silicon, it runs faster than it does on a Qualcomm chip.

Tying your average or even above-average product with some mediocre kludge warehouse that happens to be made by the same conglomerate is an established way to sink both of them.

Nvidia is the largest company and they pay TSMC to fab the GPUs they sell to cloud providers who sell them to AI companies. Intel integrated their chip development with their internal fabs and now they're getting stomped by everyone because their fabs fell behind.

What matters isn't if everything is made by the same company. What matters is if your thing is any good.

I guess you're being downvoted because you've just now realized that 1password is electron-based and you're using that discovery it to retro-actively confirm your pre-existing bias that electron = bad.

If electron was actually always bad, you wouldn't need a script to scan your machine and tell you which apps to hate, you'd just know "yep that's slop" upon first opening the app. Yet that is not the case. Because electron is a tool, and it's sometimes used so well that you don't even notice it until you run a script.

Agreed. I am more excited about completely open source models like how OlMoe does.

Atleast then things could be audited or if I as a nation lets say am worried about that they might make my software more vulnerable or something then I as a nation or any corporation as well really could also pay to audit or independently audit as well.

I hope that things like glm 4.6 or any AI model could be released open source. There was an AI model recently which completley dropped open source and its whole data was like 70Trillion or something and it became the largest open source model iirc.

Article cites manufacturers as saying that

> installing a couple of 300-watt panels will give savings of up to 30% on a typical household’s electricity bill, but there are lots of variables that come with that claim. It depends on which direction the balcony faces and whether the panels are shaded part of the day.

My german electricity bill is around 1200 euros a year. Sign me up for a one-time purchase of 426€ to save ~360€ every year if I had optimal conditions -- call it 50% effective and it's still earned back in under 3 years. The thing lasts, what, a decade? More?

(Price taken from https://kleineskraftwerk.de/products/kleines-kraftwerk-gitte... for 450W, first one I could find from some review site.)

Great idea! Want to learn more on the safety though...

> Once in place, people simply plug a micro-inverter into an available wall outlet.

later

>Gründinger and experts at the German Solar Industry Association noted that the devices don’t generate enough power to strain the grid, and their standardized design and safety features allow them to integrate into balconies smoothly and easily.

This seem to talk to the safety of the grid and the balcony. What is done when electricians power down the apartment or worse, the building to work on something? The wires remain energized despite proper distribution panel shut down. Do these setups have auto shut off if they see no other power on the plug they are on? what if it is the building, wouldn't other panels still energize the wires, so they would not shut down? Just asking, as my personal experience is quite hair raising and crispy when it comes to inappropriately de-energized circuits. ;)

>the house take on the major platforms is vastly higher than with traditional sports betting

What kind of markets is this referring to?

Polymarket still charges 0 fees. While Kalshi's fees+spread can approach or even exceed traditional sportsbooks on some markets, neither of them have any interest in banning winning players, as they don't take a side on any bet and directly benefit from more betting activity. Kalshi also pays interest on bets, which can add up on longer term positions.

Betfair has operated with a similar model for decades in the UK and elsewhere.

1. Elon could quit and do zero work and he would still own the 12%. So what is his compensation for the extra work?

2. If you owned $10M worth of shares of TSLA from your personal investments, and applied to work at TSLA, would it be reasonable to deny you any compensation since you are already incentivized and share in the success?

This is not to comment on what the right pay package is; perhaps the proposed one is far far too rich, but that's a separate question to whether his existing assets are compensation or not.

Which is a clear roadblock for third-party appstores adoption, notably F-Droid which compiles and signs the apps it distributes.

What if F-Droid distributes an app Google or its US overlords deems dangerous or illegal? Will they block and/or revoke that signature, thus taking down F-Droid in its entirety?

Ken will be missed. A true innovator and so generous with his knowledge and experience. I wasn't following his personal affairs closely so was extremely bummed by the latest events but it was great to hear from himself he found a person he believed in enough to pass the torch to.

I've had one of his electrics briefly and it felt and played great. I didn't bond with the instrument due to specific personal preferences, but it was great to feel for myself this particular guitar was as good an instrument as Parker reputation makes you expect.

Assuming you have an endless supply of food but can only take one bite per day and it means tomorrows bite will be a bit smaller.

These storage systems are generally warrantied as 5000-10000 cycles with 85% capacity remaining in 20 years time.

Guaranteed money today is better than saving a few cycles to maybe make money in 20 years time. Now also factor in discounting the risk etc. and the calculation is given.

But the business case is of course calculated on having the entire construction cost be amortized with profit over a chosen period. With some days making more money than other.

What batteries do are extending the time renewables flood the grid with cheap electricity and thus force nuclear reactors to throttle down, gas peakers to shut down etc.

Or these thermal plants can bid negative ensuring they don’t have to turn off while hurrying on their own demise.

I always through the aesthetic was meant to evoke the sense that this was a bespoke, personalized device - i.e. it has been modified and customized to work for exactly one user.

I don't think you can have a world where mass-market technology looks like that, because why would it? Engineers with time, resources and technology would do what they do now - design for manufacturability and mass-market appeal.

I think you're making the assumption that socio-economic status is the only variable.

There is also the "I have Apple, I'm creative". "I have Apple, I'm cooler than Android".

I don't know if the blue/green bubble thing is about socioeconomic differences, or if it's just about "you're not as good as I am".

If you're so sure Apple doesn't have a status feature, then what's the whole green/blue bubble about?

I share my location with 10+ people, including my partner. My wife and participating friends all know, trust and love each other and none of us care if we know where each other are, but at times where we are coordinating a plan on the fly FindMy has been incredibly useful. If I’m letting weather apps and etc know and sell my location to data brokers, letting my inner circle see my location isn’t that deep.

Rust does have a qualified compiler: Ferrocene. It supports ISO 26262 (ASIL D), IEC 61508 (SIL 4) and IEC 62304 currently, with more on the way, including plans for DO-178 I believe. It’s being driven by actual adoption, so they’ve started in automotive and will move to other industries eventually.

I suppose it depends on the context. For some couples there has been some past dishonesty, and the location sharing can serve as a measure of accountability. That doesn’t mean it’s always monitored (though I’ve definitely seen some people obsess over this to an unhealthy degree), but it helps the one who was offended feel more secure and keeps the one who did the offending honest.

While I am sure a huge portion of valuable work will be lost, I am smirking thinking of management making a call, "So, if there is any shadow IT who has been running mirror databases of valuable infrastructure, we would have a no questions asked policy on sharing that right now".

I know that I have had to keep informal copies of valuable systems because the real source of truth is continually patched,offline,churn,whatever.

This is an insightful response. Thank you to share.

Your last sentence:

"NK hackers" reminds me "my homework was eaten by a dog". It's always NK hackers that steal data/crypto and there is absolutely no possibility to do something with it or restore the data, because you know they transfer the info on a hard disk and they shoot it with an AD! Like that general!

How do we know it's NK? Because there are comments in north-korean language, duh! Why are you asking, are you russian bot or smt??

I have been working on this modular open source design for a while and will start taking pre-orders next week on Kickstarter.

https://www.kickstarter.com/projects/ubopod/ubo-pod-hackable...

You can watch a more in-depth video of the functionality here:

https://www.youtube.com/watch?v=zBFd0aLzWAk

this is a fully open source product (hardware & software). The software stack uses Pipecat under the hood for voice/vision ai orchestration.

The core uses a redux-based event driven reactive design that communicates with various pluggable services. For more on the software side, check the repo here:

Assume every investor is interested in profit, but then secondary, what else are they interested in.

I have a friend who is an African founder, and has really struggled to raise. From their experience, they say the VCs that focus on under-represented founders are often predatory in nature. As a white guy, I can't comment on that.

There are definitely investors who have themes around health, media, environment, etc.

The success metrics are still "how much money can I make from this", but it's also "how many lives can I positively impact".

So I wouldn't put these investors on the opposite end of the spectrum. It's a balance of "if we can help x number of people with Y problem, that's worth Z". VS "If X number will pay us Y, how much money can we make?"

It's a very subtle difference. You're not going to find an investor who says "I want to see Y happen, I don't care about the investment". That's philanthropy.

It might be different “they”s. Putting on my tinfoil hat, whoever was going to be in hot water over the hack burns it down and now the blame shifts from them to whoever manages G-drive and don’t have a backup plan.

Not saying I believe this (or even know enough to have an opinion), but it’s always important to not anthropomorphize a large organization. The government isn’t one person (even in totalitarian societies) but an organization that contains large numbers of people who may all have their own motivations.

You're right -- a lot of people who yearn for the spatial Finder don't remember how many fewer files/folders we had in the past, with a lot less hierarchy.

But for those who loved the spatial Finder and did indeed have nontrivial numbers of files, well, some people just have exceptional visual memory. Think of those who have thousands of books in their house with seemingly loose-to-no organization, yet can quickly retrieve any volume. Or cooks with pantries that seem to lack any rhyme or reason, yet they can immediately find any ingredient.

The one person I know who loved the classic Mac OS spatial Finder and dealt with nontrivial numbers of files worked exactly like that. Their files were organized in haphazard piles across an incredibly cluttered desktop and a handful of folders, yet they could always track down what they needed. Their brain was essentially a flat key->value store that mapped files -> screen coordinates. It didn't map files -> filenames (lots of "memo_1.doc"), and it certainly had no notion of hierarchical keys.

I share my location with a couple of people who, 99.9% of the time do not need it but 0.1% of the time it is rather useful.

I do not care if they know where I am, I do not care if they have commentary about my location. I guess if they got weird about it I would turn it off but I could not imagine a situation where that would be true.

It's not "dangerous", I am as unbothered by any consequence of my location being known by them as it is possible to be.

It is entirely possible to have actually healthy relationships where people respect having information available to them and not abusing that information. It is also possible to have relationships with people where you actually don't care about each other's business.

> is there a reason

Using more modifiers reduces the odds of conflicting with any other existing shortcut/hotkey - and since the intent is that the combination is only ever generated automatically with the CoPilot key - there's no issue with users having to remember or perform it. The problem isn't with them using all those modifiers, it's that they are doing it in a non-standard way that breaks remapping that key. They could have easily used all those modifiers in a way that doesn't break full remapping.

3000 hp? Not sure if that's measured at the "crank" or the dynamo, but that's over 2MW, probably pushing 2.5MW of power draw from the batteries assuming a motor efficiency of 90% and some other losses. Apparently that's getting drawn at 1.2kV from the batteries, so "only" around 2kA of current draw.

That top power draw would drain the 80kWh batteries in around 2 minutes, though I'm guessing you'd hit thermal throttling or catastrophic failure before that. The batteries are allegedly rated to 30C, meaning 2 minutes to full discharge at max current.

I'm curious how the heat dissipation of EVs compares to ICE vehicles. You have much higher efficiency vs combustion and get to split the power between 4 motors instead of one engine, but you don't get the heat capacity of a massive engine block, or the convection of cold air intake + hot exhaust out the tailpipe.
