You can construct any arbitrary deal terms you like, of course, but in the Silicon Valley ecosystem nobody you'd want to raise money from does this. Deal terms are broadly standardized and the desirable investors only do clean term sheets. Quoting myself from another thread a couple years ago: VCs make their money from outlier companies, so the competent ones don't optimize for worst-case outcomes. You'll never see a dirty term sheet (e.g. liquidation preference > 1x) from Sequoia, for example, because they don't return 8x on a fund by squeezing pennies out of failed startups.

To answer your question, yes, doling out company value to different share classes is part of the 409A calculation. I've used Carta and Pulley for this, but it looks like neither has their docs posted publicly. Here's Pulley's overview page from our last 409A, though:

Valuation Analysis

To determine the fair market value of the Subject Interest in our analysis, the following steps were taken:

Step 1 - Determine the value of the Company using an appropriate methodology(ies)

Step 2 - Allocate the value of the Company to the various share classes taking into account share classes economic rights and preferences

Step 3 - Apply a discount for lack of marketability (“DLOM”) to the resulting per share value of common

Step 4 - Analyze any secondary transactions that have incurred in the past and determine to what extent they should be considered relevant in determining the value of the Subject Interest in the analysis

The system is built to handle non-standard liquidation preferences, but anything more esoteric (e.g. your participating preferred shares) probably needs a bespoke valuation. You won't see this stuff from successful VCs, though. It would be a bit like investing in SpaceX, but having one of the terms be an increase in Earth's gravity.

You can't have this argument in good faith at the present moment because the institution is under attack not because of a pragmatic reason as you describe but because the joke of a president is mad at a private citizen for their speech. Ignoring all previous Musk love or hate that somebody may have, look at the action that may take place here - the government taking adverse action against a private citizen for their speech.

We can have the pragmatic discussion AFTER the fascism is over.

Walmart is installing EV chargers at thousands of their locations. Tesla colocated at Meijer, some Targets, etc. Grocery stores, airports (Chattanooga airport hosts a Tesla charging station), anywhere people go today and there is power can be one.

Petrol won’t go away overnight, but it will reach tipping points where it’s no longer cost effective to deliver it to areas or host a petrol station once an inflection point occurs with regards to demand.

On what planet do iOS contractors make $2500/day?

That aside, 1) the author is not an experienced iOS dev 2) hourly rates != cost, and 3) you can certainly get the same app built for under $1000 by a freelancer.

You also seem to have accidentally used a $0.99 price instead of $2.99.

Real break-even would be closer to 1k-2k sales.

I'm not entirely convinced that nations will play as significant a role in the coming decades as they have historically. Currently, we observe a trend where affluent individuals are increasingly consolidating power, a phenomenon that is becoming more apparent in the public sphere. Notably, these individuals are also at the forefront of owning and controlling advancements in artificial intelligence. Coincidentally, this trend is often referred to as 'tech fascism,' bringing us back to the dictator schema.

Titanium has an undeniable "cool factor" due to its use in aerospace, but everyone needs to understand that this is just a case of material science nerds doing something cool in a lab, and there will be no "widespread use in industry" even if they do fix the other issues mentioned in the article - and even if someone manages to figure out a way to viably scale up the process to an industrial level.

The reason? Titanium sucks to work with.

Machinists hate it, equipment hates it, cutting tools hate it, and it makes shavings that can burn hot enough to go right through equipment and concrete floors. That's what makes titanium parts so expensive, not just the material cost alone. It absolutely has properties that make it a perfect material for specific situations, but making it cheaper to buy definitely won't make titanium a common every day thing.

So - enjoy the science! Give a round of applause for the cool new method this team figured out. And then go back to appreciating how wild it is that titanium parts can even be produced at all, because holy smokes is it a pain in the rear in almost every way...

The video has covers how Tool and Die wages have dropped below the median wage. We're also importing the tools/molds from China and manufacturing the parts "in the US" instead of the reverse.

I remember another Youtuber Linus Tech Tips creating their own injection molds in BC so that it would be harder for copycats. The entire Screwdriver isn't made in Canada though. The shaft and bits are made in China or somewhere else in Asia IIRC. The reason they were able to do that though is because there already existed an injection molding company nearby for them to work with though.

> You pay a lot upfront for the hardware, but if your usage of the GPU is heavy, then you save a lot of money in the long run.

Last I saw data on this wasn’t true. A like for like comparison (same model and quant) API is cheaper than elec so you never make back hardware cost. That was a year ago and api costs have plummeted so I’d imagine it’s even worse now.

Datacenters have cheaper elec, can do batch inference at scale and more efficient cards. And that’s before we consider the huge free allowances by Google etc

Own AI gear is cool…but not due to economics

>Benefiting the most vulnerable people of the community seems a bit much though.

it makes sense contextually.

if there is some holy manifest that urges people to do a thing even when they're old/invalid/bed-ridden/sick, and there are people that will devoutly follow this rule, then it stands to reason that those people will feel a burden eased when part of the manifest is accomplished automatically.

We’ve got a temporarily underutilized 64 x AMD MI300X cluster, so instead of letting it sit idle, we’re opening it up for LLM inference.

Running: LLaMA 4 Maverick, DeepSeek V3, R1, and R1-0528. Want another open model? Let us know. We are happy to deploy it.

Prices are around 50% lower than the cheapest OpenRouter endpoints, and they will stay that way through June (maybe July).

The server handles up to 10,000 requests/sec, and we allocate GPUs per model based on demand. So feel free to load-test it, hammer it, or run production traffic. We're collecting no data whatsoever.

cloudrift.ai/inference

Full disclosure: I am the founder. We're trying to make good use of this capacity. Let us know if you have any ideas on how to utilize the cluster meaningfully. We're happy to hear the feedback.

> A sufficiently advanced algorithm will be able to find everything a person has ever posted online (by cross referencing, writing style, etc.)

Is this like a sufficiently smart compiler? :)

Stylometry is well-studied. You'll be happy to know that it is only practical when there are few suspect authors for a post and each author has a significant amount of text to sample. So, tying a pseudonymous post back to an author where anyone and everybody is a potential suspect is totally infeasible in the vast majority of cases. In the few cases where it is practical, it only creates a weak signal for further investigation at best.

You might enjoy the paper Adversarial Stylometry: Circumventing Authorship Recognition to Preserve Privacy and Anonymity by Greenstadt et al.

It’s not just that. Companies who are anywhere between unethical and outright complete scams have discovered how incredibly easy it is to get people to sign up for a free trial for something that milks them of tons of money they don’t realize.

Despite the fact that Apple tells you when your subscription will renew it doesn’t seem to help enough people. So they buy a scientific calculator app because they don’t realize that it’s built into the one on the phone and then end up paying five dollars a week for it. And even if they find out after the first renewal that means the app developer got five dollars (minus fees).

There’s tons of subscriptions out there that are just completely out of whack with their prices. And Apple just doesn’t seem to care.

I would expect to this to be a similar effect to consuming certain types of fiber. It would increase fullness, and thus, satiety, improve gut microbes, and slow carbohydrate absorption so as to spread out blood glucose levels. Cellulose itself is a component of plant material and I would expect it to have very similar properties to fiber in the GI tract. [1] This is a type of treated or chemically altered form of cellulose that they're using in the study. Why acetylate cellulose in the first place? My cynical mind first assumes there's probably a economic goal in mind, such as that no one has patented it for that purpose yet.

In regards to fibers that act in a similar way, it's been a long time since I looked at all the different fiber products that are sold on the market, but one I remember looking at years ago that purported to have properties like this was glucomannan. A quick search with results from a reliable site will tell you if it would be worth your trouble [2], but it's also about if the product is palatable to you and you're willing to use it regularly.

In that case, any kind of soluble fiber from ground up seeds or even cheap psyllium husk supplements could help achieve a similar result. Just be sure to follow the instructions and take the products with PLENTY of water as they form a gel in your GI tract. These kinds of products can take weeks-months of consistent usage to be effective and adding additional fiber to your diet is always a healthy option.

The American Heart Association & other groups recommend trying to achieve 25g to even 45g of fiber daily [3] which is a crazy high amount most people have a difficult time achieving as it is, so even striving to incorporate more fiber rich foods in your diet can be helpful, outside of trying to add any kind of supplement on top.

determine their views and opinions with high accuracy

The truth, accuracy doesn't matter to authoritarians. It doesn't matter to Trump, clearly, people are being sent away with zero evidence, sometimes without formal charges. That's the point of authoritarianism. The leader just does as he wishes. AI is not enabling Trump, the feckless system of checks and balances is. Similarly, W lied about wmd's, to get us into an endless war. It doesn't matter that this reason wasn't truthful. He got away with it and enriched himself and defense contractor buddies at the expense of the American people.

> By that reasoning, nothing is safe. Not a useful statement.

The difference is, I think, that guns are specifically designed to be destructive. Their purpose is to kill things, and not only is that their purpose, it's actually their only purpose. They can't do anything else.

This is in direct contrast to, well, everything. Knives, automobiles, you name it.

> benefits the most vulnerable people of the community.

I suspect the author may have misunderstood what this is euphemistically referring to. I think the original source means women. A lot of routine elements of childcare fall within this restriction, and in conservative communities that would be the exclusive domain of women. Without the eruv women with young children would be confined to their home during this part of the week.

I was experimenting with OpenAI's streaming API and had a weird thought: what happens if you intercept and corrupt tokens as they're being generated, rather than after completion? Built a simple Python script that transforms every odd token in real-time - reversing characters, adding noise, uppercasing, etc. The results were unexpectedly interesting. LLMs maintain coherent meaning even with 50% of tokens corrupted. A sentence like "The quick brown fox jumps over the lazy dog" becomes "The kciuq brown xof jumps revo the yzal dog" but remains largely comprehensible. More surprisingly, the semantic degradation isn't linear. Technical explanations break down faster than creative writing. Mathematical content becomes nonsense immediately, while stories can handle significant corruption. This suggests something about how these models encode information - maybe redundancy is built deeper into the token relationships than we assumed. The tool is dead simple (100 lines of Python) but opens up some research questions I hadn't considered:

How much disruption can different model architectures handle? Does token position matter more than token content for meaning preservation? Could this be used for real-time LLM steering or interpretability research?

Not sure if this is useful to anyone else, but it's been a fun way to poke at how these systems actually work under the hood. The streaming interception approach might have applications beyond just corruption experiments.
Show HN: Pyvers – Python library for handling BCB changes and multiple back ends
by vmoens | 2025-06-09 00:18:46+00:00
pyvers is a lightweight Python library that lets you write version-specific implementations of functions to handle breaking changes in dependencies or switch between different backends (e.g., CPU/GPU, numpy/jax/torch) without cluttering your code with conditionals.

Example use case: NumPy 2.0 changed bool8 to bool_. With pyvers, you can handle both versions elegantly:

```python @implement_for("numpy", from_version=None, to_version="2.0.0") def create_mask(arr): np = get_backend("numpy") return np.array([x > 0 for x in arr], dtype=np.bool8)

@implement_for("numpy", from_version="2.0.0") def create_mask(arr): np = get_backend("numpy") return np.array([x > 0 for x in arr], dtype=np.bool_) ```

The README.md gives you a more complete example, including using Jax as a backend.

Other real-world examples: - Switching between SciPy (CPU) and CuPy (GPU) sparse matrix operations - Using various libraries for linalg depending on resources: torch, numpy, jax - Handling gym → gymnasium breaking changes in RL libraries

The library is battle-tested: we've been using it in production in several robotic projects to handle BC-breaking changes in our dependencies for the past four years.

will it sell gas?

Yes and especially diesel which will not go away for a few generations. There are no EV replacements for heavy trucks and they do not appear to be viable yet. 3500 through 7500 series. Battery tech will have to make science fiction level improvements. When those trucks are gone society comes to a stand-still. Comparison to earth moving equipment in mines do not apply.

what convenience items will it sell?

The popular versions of what they sell today and is known to bring in revenue.

who, if anyone, will staff it?

Mostly high-school kids, some people that do not have the confidence to move on and some with criminal backgrounds.

what payment methods will it accept?

Credit, Debit, Cash. Maybe bitcoin.

will it offer new services?

If they have the parking lot space then there may be battery swap stations to quickly swap out EV packs, offer paid upgrades to newer batteries and battery tech every few years.

There are other currents in Judaism, such as mystical based, or philosophy based (Spinoza), but they are a minority nowadays.

The mainstream Judaism has focused mostly on codifying rules for all situations in life, which has evolved into a semi legalistic framework of rules and their loopholes. So many loopholes... Like temporarily selling your belongings 1 week per year to bypass Passover rules about Hametz, etc.

Also check for firmware requirements - some devices enumerate but fail on ifup without firmware available. The android UI naturally can't cope with this, only dmesg tells you what's going on. Though not sure if CDC devices require this? Though a lot of adapters are (were?) based on Realtek or Kawasaki chips that did.

I guess this android change is relatively recent though, as we regularly used USB network dongles on our debug devices (that used 100% "Vanilla" AOSP). Or perhaps a kernel change, or a quirk of the CDC driver to name the device usb*? You just had to be careful which chipset the dongle used and ensure it didn't need any firmware.

Say you have several MCPs installed on a coding agent. One is a web search MCP and the other can run shell commands. Your project uses an AI-related package created by a malicious person who knows than an AI will be reading their docs. They put a prompt injection in the docs that asks the LLM to use the command runner MCP to curl a malicious bash script and execute it. Seems pretty plausible no?

> Why would you choose to give little review to a dependency?

Given finite developer hours, what activity has the highest security impact per hour - is it reviewing the dependency graph? That's not the choice most projects are making. Maybe they are wrong. Or maybe they know where to spend their time for better impact. I dunno...

I have worked in commercial codebases that vendored 100% of their dependencies (including kernel and driver source) and reviewed large swathes of those dependencies carefully. I'm absolutely not dismissive of this. I think we agree more people should be doing it.

However, over the decases, I've seen very few projects take this approach. Many choose to trust third party code (naively, as you point out!). If that's the reality, I think we should continue to work on improving provenance, automated signature verification, and other tooling so we can at least better know that if we choose to trust foobar, it's actually foobar who is distributing foobar 1.0.2.

The AI comment is provocative - can future-AI find vulnerabilities better than future-AI can inject hard-to-find vulnerabilities? And how do we know our AI reviewers themselves aren't hacked... a horrible twist on https://www.cs.cmu.edu/~rdriley/487/papers/Thompson_1984_Ref....

As many as you can control with signal chat.

Besides, I'm not sure if tanks like the Abrams are as important anymore. Nowadays, things like food and water really matter. For example, exporting corn is crucial. Also, having the soils needed to make modern tech, like chips and batteries, is super important. Therefore Greenland is.
