The lack of acknowledgement of the threat of prompt injection in this new initiative to help people "responsibly deploy generative AI models and experiences" is baffling to me.

I found a single reference to it in the 27 page Responsible Use Guide which incorrectly described it as "attempts to circumvent content restrictions"!

"CyberSecEval: A benchmark for evaluating the cybersecurity risks of large language models" sounds promising... but no, it only addresses the risk of code generating models producing insecure code, and the risk of attackers using LLMs to help them create new attacks.

And "Llama Guard: LLM-based Input-Output Safeguard for Human-AI Conversations" is only concerned with spotting toxic content (in English) across several categories - though I'm glad they didn't try to release a model that detects prompt injection since I remain very skeptical of that approach.

I'm certain prompt injection is the single biggest challenge we need to overcome in order to responsibly deploy a wide range of applications built on top of LLMs - the "personal AI assistant" is the best example, since prompt injection means that any time an LLM has access to both private data and untrusted inputs (like emails it has to summarize) there is a risk of something going wrong: https://simonwillison.net/2023/May/2/prompt-injection-explai...

I guess saying "if you're hoping for a fix for prompt injection we haven't got one yet, sorry about that" isn't a great message to include in your AI safety announcement, but it feels like Meta AI are currently hiding the single biggest security threat to LLM systems under a rug.
> The gradient computation is only ill-defined at places where a spike would get added or deleted.

I feel like I'm missing something here. Like if you do it naively, the gradient is zero when a spike isn't added or deleted. And infinite when it is. Which is completely unhelpful.

Now the "natural" solution is to invent some differentiable approximation of the spiking network, and compute derivates of that, and hope that the approximation is close enough that optimizing it leads to the spiking network learning something useful.

A more principled version might be to inject some noise into the network. This would mean that you have a probability of spiking in a certain pattern (or better, a class of patterns that all have the same semantic). You could differentiate the probability of correct output with respect to the weights and try to drive it towards 1.

Is your approach in either of these classes?
Out of curiosity, is Windows your requirement? I wonder how would benchmark on Linux look compared to what you measured on Windows.

> That is an age old debate in unions, how to agree on what to fight for.

That's not what the poster I replied to was arguing - they were arguing for developers to all agree not to develop harmful (to the consumer) products.

That is not what unions do. Unions are not known for acting in the customers best interest. They are a workers collective, not a consumer advocacy group.
> Does IF Metall already represent all of Tesla's employees? Does that mean there are no active Tesla services in Sweden during the strike?

From what I understand they initiated action on behalf of Tesla's workers and did not need to represent all or most of those employees to initiate the strike.
Power steering pumps are electric and have one of the largest wires in my truck. With an EV you also have a heat pump, maybe a heater, coolant pumps now that you don't a constant spinning pulley, windows, lights, headlamps, power doors, seats, radio, amplifier, small PC, etc.

From the article
"Switching to 48V architecture alleviates a huge number of challenges automakers are facing with 12V. The biggest one, though, is complexity: You need far less complex wiring harnesses to power all your vehicle systems"

My take is that 12v requires almost a dedicated power line for each part, while a 48v could run to a bus line that gets tapped. 48v might be something that divides easier with the battery pack, and drops the 12v battery.

TOML2Pbf is a PC utility that converts configuration files from the TOML (Tom's Obvious, Minimal Language) format to the Parameters Binary File (PBF) format. This tool is particularly designed for systems where reading text-based configuration files such as XML, JSON, or YAML is resource-intensive and impractical, such as on embedded platforms.
This is my understanding as well. It's also my understanding that it's not illegal to coordinate with other executives when you're selling throughout the year and then drop news that influences the price in a particular direction just before or after time of sale in order to ensure that you profit.

Taking a risk that doesn't pan out can also be a bad idea, though. It depends on what the possible outcomes were and what the chances of each outcome were.

The important thing to evaluating someone's decision making ability is to look at the decision they made with the information they had. Was it a good bet to dramatically overhire? I don't know!, but analysts can and should (rather, have no excuse not to). It's possible to determine what information the C-suite had access to and how risky they believed the decision to be. Did they play fast and loose with peoples' livelihoods for a tiny chance of unsustainable profit? Might be a bad decision.
Anything drawing over 250 watts is going to need over 12 gauge wire. I put a 2200 watt inverter in my truck and I needed to put 4/0 gauge cables to it which are huge. 48v would mean I could have gotten away with only 8 gauge wire.
Growing food absolutely harms the environment. Maybe not one potato, but modern agriculture is a leading cause of climate change (mostly animal ag, but the point remains).

This is not nihilism. This is what capitalism is by definition. Says Rob Urie:

> Economic production that produces toxic externalities like global warming, dead oceans, undrinkable water, unbreathable air, etc, depends on assigning little or no value to these. To make this very clear, Western economic ‘accounting’ places no value on these, on the most fundamental necessities of living beings, by design. As Oscar Wilde put it, a cynic is someone who knows the price of everything and the value of nothing. This is in fact a summation of Western economics; circumscription of the ‘knowable’ world by what has had a price tag put on it. The externalized costs of capitalist production are real— more real than the stuff in stores that is only ‘cheap’ because the true costs were lobbed off on people who haven’t yet fought back.

Why don’t you try to change society then? Honest question why do people always want someone else to do it?

Go start a business with your friends who think same way. See if you can build a business that can take care of its employees and do something good.

You could change your own life and that of your colleagues.

Never go public, and you don’t have any pressure to grow at all costs. Don’t take on debt.

Oh right. It’s literally a week of effort to do some LC and get a 400k job lol.

Compared to a monumentally larger effort to start and sustain a business, which may or may not even make it a year.
lol, this is so stupid. Don't they realise that people usually develop locally and train on a server? You don't need a super beefy GPUs to do it, so you buy nvidia.

Approaching your work as contracting (even if you are regular employee) helps to think about the job more rationally. You exchange x hours of time for y amount of money. Also helps to keep in mind to check you value in the job market.

There are positions where you can just stay put engineering all day but entails being an irreplaceable resource to your employer - so only few generally can get to this niche.

The OC's perspective is that one is entitled to income and being laid off is a regression. In reality, being laid off is a return to stasis.

Or the debug in vscode, then again in vscode you can edit the code also. Maybe this console has VM binding. Just feel like it should just be a vscode plugin.
I think excluding data and sources is both censorship, and something more.

Excluding data is censoring from them model. Then when the model provides incorrect or biased, the firm is actively deceiving the user.

Transcript:

. . . a little bit about electrical electrical engineering um you don't need to know a lot but just a little bit uh we'll understand that you actually want a higher voltage in order to reduce the resistance losses.

So the heating in any wire is the current is the square of the current. So if you're trying to get a particular power rating through then as you increase the voltage you can decrease the current. Voltage times amperage equals your power. To hold power constant, the heating is is proportionate to the square of the current. So you want to raise the voltage in order to lower the current thus lower the heating in the wire.

And the net effect being that you can have much thinner wires, then as you raise the voltage you can you can drop the the the thickness of the wires. You can have much you can use much less, in a nutshell. You can use much less copper and the wire harness weighs much less as you raised the voltage.

There have been many attempts, usually formed by ignoring the inherent difficulty of creating secure communications while fundamentally being the exact same UX as GPG. It's genuinely incredibly tedious to see there is a new "alternative" and find out once again folks are over-promising and under-delivering.
Sigh. And my pixel 4a is outside the window.
In dev-mode is use a separate monitor that logs human friendly output. That output is generated by frontend and backend and transfered via socket (errors too). I run automatically on save only that part of the app, that i am working on, normally with a test.

Only in a few special cases i need to debug and traverse errors step by step.

I can not understand why people use complicated bloated tools, in which you must click so many times until you get all needed data. Good log output is for me the best solution.
We humans are all terrible on some level (except my mom, she was a saint), but if you have enormous power, you can help or hurt a lot of people based on your actions. Musk has a lot of power. He must be a terribly lonely person, not knowing if he can trust anyone or they just want something from him.
You can use LFP cells (don't suffer from thermal runaway) with a good BMS to avoid this risk.
Show HN: Croppy – Perfect images for your websites from your customers
Right now, we are testing a new method for website image preparation.
This is aimed at people and companies who build websites for clients and want to ensure that images are always perfectly sized and compressed.
More information can be found on the homepage.

The following are the recommended steps:
- Make an entry for the website on the croppy admin
- Allocate upload credentials, predefine several picture resolutions and compression formats
- Send the link to your clients, allowing them to crop and upload images directly onto the website

As we are in beta, we look forward to all feedback possible. On the website, you may experiment with the demo croppers and different set resolutions.
If you prefer using it with your wordpress site or ftp server, you need to create an account.
I think we agree[0] on this. Email encryption isn't ever going to be a thing because of the way email itself works. But email signing would help a lot. I still don't think GPG does this very well, though, because of issues with key rotation/invalidation/etc.

Instruction count is not everything but when something is 10x larger, unless the 1x is extremely complicated, I think it is safe to expect that the 10x version will run slower. This 1x version is extremely trivial despite that one branch.

.L4:
mov edx, edi
and edx, 1
cmp edx, 1
sbb eax, -1
shr edi
jne .L4
ret

In the first run, jne might be mispredicted (equating to a pipeline flush, ~15 cycles) but in all the other consecutive runs it will be predicted correctly. This means that the larger the amount of iterations is, cost of the first misprediction becomes more and more negligible.

Vectorized execution OTOH is not cheap and does not necessarily result in faster code so purely seeing it in assembly would not mean much without actually measuring it. Scalar versions of the same code may be faster than the compiler-generated auto-vectorization code.

Each SIMD instruction has a latency attached to it (see https://www.intel.com/content/www/us/en/docs/intrinsics-guid...) and the majority of those SIMD latencies are in between 1 and 7 CPU cycles so definitely not free as in a free beer.

That said, I am surprised by the results - in my mental model of how things work this does not add up. Rust assembly is ~50 instructions, roughly ~30 of them being vector (SIMD) instructions and the rest of ~20 instructions being the superset of (only) 6 instructions used in C++ assembly. I cannot see how those 6 instructions, even with the branch mispredict cost of ~15 cycles, can run ~2.5x slower than the pretty much convoluted version of the SIMD popcnt.
I think it's reasonable for people to be frustrated that laying people off (lost value/income/security for many) consistently translates into big payoffs (more money) for fewer others (CEOs, shareholders). It feels like a moral inversion.
The savings in terms of weight and efficiency are actually significant. This was covered in Tesla's investor day presentation earlier in the year:

> Say 80% of developers at a company think that the new feature of addicting kids on some game mechanic is harmful?

Who cares? The company will just get someone from the other 20% to develop it. Or contract it out.

What is your proposal for stopping a company from developing something you think is harmful? You can't very well complain that other developers have to agree with your opinions[1], after all.

[1] Whether something is harmful or not is simply your opinion. If that something is a fact, then there's probably a law against it, so there's no need to prevent other developers from developing it.
From my understanding of your description, "Tarifvertrag", is more like a "convention collective" in France.

If that's the case, then Tesla would have been subject to the CC as well, regardless of the unionised status of the employees.

Some devices in a car are still pretty power hungry. Eg. The blower motor for the fan (typically 800 watts = 70 amps @12v). Heated rear screen (240 watts = 20 amps). Window motors are pretty powerful too.

End result is you need a lot of fairly chunky cables to power those things.

And the price of copper has been steadily climbing since 1960 - unlike other commodities which have been getting easier and easier to extract with more automation in mines.
Why stop there? Should to back to the good old days of Pinkertons and military having a small scale war with strikers. And corporations knowingly letting workers work in conditions that will kill them to earns a few dollars more.

Only someone ignorant of history can spout nonsense like this.
The CFO let Spotify hire all of these people based on his projections and assumptions, maybe he should've been one of them let go.
This is why benefits shouldn't be means-tested.
I meant on a "moral" level, not legally speaking. If he's doing his job as a CFO and he wants to sell shares when people are laid off, that's up to him.
I see power management mentioned often, but I'm not convinced. How does centralizing the push service reduce power? Why can't a developer just implement the service in the same way? (if Apple/Google let them)

I self-host Gotify, which just uses a websocket for the push part, and battery consumption is only 2%/day even with the app white listed from "optimization"
That's wild! As a (pseudo-) government agency, it seems like the postal service shouldn't be legally allowed to pick and choose whose mail to deliver and whose to withhold.
Thanks to good planning by the union, the workers are being compensated - but the point remains that the striking workers aren't costing the employer any money, which was one commenter's claim for why it's unfair to Tesla.
We are in an age of shamelessness and self-interest.

There's no story in the world that will get people to stop using services like Whatsapp or Instagram.

The only thing stopping these big companies is potentially setting a legal precedent that interop projects are legal.

They can potentially win such a case as it stands because the targets for their threats are few and far between.

If we as digital humans want to solidify this digital right then we need to have a unified front against threats like this. That means we need to have an OSS union behind which companies and individuals can unify if a precedent setting case ever does come up
