Right, so a filter that sits behind the model and blocks certain undesirable responses. Which you have to assume is something the creators already have, but products built on top of it would want the knobs turned differently. Fair enough.

I'm personally somewhat surprised that things like system prompts get through, as that's literally a known string, not a vague "such and such are taboo concepts". I also don't see much harm in it, but given _that_ you want to block it, do you really need a whole other network for that?

FWIW by "input" I was referring to what the other commenter mentioned: it's almost certainly explicitly present in the training set. Maybe that's why "leetspeak" works -- because that's how the original authors got it past the filters of reddit, forums, etc?

If the model can really work out how to make a bomb from first principles, then they're way more capable than I thought. And, come to think of it, probably also clever enough to encode the message so that it gets through...

Democracy built lies, decide, and rejection of facts through propaganda.

Really need a viable means to fight it, say allowing an elected official's constitutes being able to sue them for no less than $10,000 for incidence of bearing false witness. Help erode the dark money networks.

Also having a 4th branch of Governments, the people with State and Federal binding resolution, would help. Only way to overrides those in power is to unionize the will.

Why would I trust that an "entertainment" network like fox news would provide a good legal analysis of how a judge messed up the law? LLMs are worse than this.

ICE has been regularly overstepping its bounds and going after people in ways that impact our legal system's ability to function. This is a terrible precedent to set for no other reason than it impacts the rule of law. If people who are accused of crimes can be disappeared without a trial, just for showing up to court, what incentive is there for anyone to go to court? They are literally ignoring the "innocent until proven guilty" that is critical to the rule of law.

If you take away people's ability to get justice within the system, you are making it inevitable that they will go outside the system to get justice.

Very cool idea! It reminds me of how software works— you usually drag an LFO to the knob to modulate a parameter.

A few people have pointed out that the knob can act as an attenuator when it's being modulated via a jack, but sometimes the goal is space. I can also imagine a version of this that uses the same technique, but where the knob has an audio jack on it. You wouldn't need to unplug it to connect the incoming cable, and you could use the still-connected knob as an attenuator if you wanted to. This would get you the best of all worlds— maximum space, an intuitive interface, and attenuators if you so choose to have them.

Where? When?

> when it was being used for whatever they consider good

Doing anything is bad when it is used for something bad and good when used for something good. Government in general isn't bad just because of the existence of DPRK.

Santos isn’t comparable: he was charged under an administration which followed the law, at a time when his vote didn’t affect the balance of power, and he also lied to his fellow Republicans. Based on what we’ve seen so far with a newly-politicized DOJ, it’s debatable whether he’d have the same outcome now or be seen as a very safe vote after being given a deal like Eric Adams to avoid punishment as long as he toes the line.

While it’s true that the president can set policy, there’s no evidence that he’s done so in this case. You’ve made a really concerted effort to try to imagine scenarios where this wouldn’t be a big deal but there’s no evidence that they’re real. For example, if Trump had decreed that personal devices were approved for classified messages, you’d expect that Hegseth would have defended himself by pointing to that memo.
Show HN: VacayBuddy – PTO Management Inside Slack (Open Source)
by letnaturebe | 2025-04-26 01:20:51+00:00
I built VacayBuddy, an open-source Slack bot that makes managing Paid Time Off (PTO) simple and seamless — all from within Slack.

Features: • Request and track PTO directly from the Slack app home • Get notified and approve PTO via Slack modals • Admin dashboard to manage team PTO balances and history • Excel integration for migrating existing PTO data • Works out of the box with SQLite for local setup

We use it internally to manage our team’s PTO without emails or spreadsheets. Would love your feedback or contributions!

I broadly agree that the economy works that way, but I’m somewhat doubtful that “running on desperation” is quite the right way to describe it. It seems a bit reductive.

Consider joining the military. Most Americans would never consider enlisting. There are people who consider possibly getting shot at or killed to be worth it. Maybe some of them were desperate when they joined, but often not.

Similarly, people who decide to immigrate to the US have a variety of motivations. Is hoping for a better life desperate? It depends.

Sometimes people regret their choices in life, which means they had choices and the other choice wasn’t obviously worse, in retrospect.

More generally, there are a lot of ways that people can get into situations that feel like a trap, and a bad job could be one of them.

This is a pretty cool study with some interesting findings! Cancer immunotherapy has a long history but has become very prominent in recent years. (Fun fact: the senior author on this paper, Ed Engleman, co-founded of one of the first cancer cell therapy companies, Dendreon, in the early 90s). However, the success of immunotherapies has been limited by the immune-exclusionary nature of the tumor microenvironment (TME). Why some tumors are immune-hot and others are immune-cold is still a very open research question.

In this study, the authors demonstrate pretty convincingly that erythropoietin (EPO, a hormone that stimulates red blood cell production in the bone marrow) reduces the recruitment of tumor-cell-killing T cells to the TME. It does this by acting on tumor macrophages, another type of immune cell, and changes the state of these cells to facilitate accumulation of immunosuppressive cells.

They work out the mechanism largely through mouse models and associative analysis in human tissue samples, but I thought it was interesting that this finding aligns with the clinical observation that cancer patients who receive recombinant EPO for treatment of anemia frequently experience tumor progression.

After reading this, I am going back to check out EPO expression in old datasets that I worked with haha.

Not sure that applies to arbitrary documents that the bearer claims is a warrant, rather than a judge-signed warrant.

Either way, it wasn't illegal to send them to where they needed to go, and it wasn't illegal to let this dude use another door, so the illegality seems to depend on whether the executive can concoct their own warrants without any oversight and gain arbitrary access for arbitrary reasons.

> The judge seems to have deliberately escorted the defendant to the jury room for the purpose of letting them hide/escape arrest.

Was the judge, beforehand, served with a judge-signed warrant indicating that they intended to, and were authorized to, arrest this person? If not, then it wasn't letting them escape arrest, it was letting them escape from 2 random dudes who may or may not even be law enforcement, much less law enforcement judicially authorized to arrest the dude.

The sizes aren't what I said you'd made up. The series is, because of course this doesn't work properly with your scheme:

Let's try, start with 216 x 279 Letter and we'll scale that so we can fit two on the 279 long side, so they're just under 140mm wide now, memo size, but um, when we do that the scaled down pages are only 180mm high, even though they've got 216mm - there's a huge amount of empty white space wasted (at the top, or the bottom, or both) and that's because this ratio does not work.

Secretary of Defense and President control classification authority

Article regarding the CIA director you mentioned.

https://www.texastribune.org/2025/03/25/texas-cia-director-g...

—- “The Secretary of Defense is the original classification authority," Ratcliffe said, "and my understanding is that um his comments are that any information that he shared was not classified.”

—-

So, I am back to what I have been saying from the beginning.

This is an AP hit piece via corrupt MSM and until someone can point to further evidence from these unknown “sources” then this story can’t be trusted.

It's not insignificant, if a company is putting out a free product foe the masses, it's good that they limit malicious usage. And in this case, malicious or safe, refers to legal.

That said, one should not conflate a free version blocking malicious usage, with AI being safe or not used maliciously at all.

It's just a small subset

> is this really a big deal given you run ./configure once

I end up running it dozens of times when changing versions, checking out different branches, chasing dependencies.

It’s a big deal.

> it's like systemd trading off non-determinism for boot speed, when it takes 5 minutes to get through the POST

5 minute POST time is a bad analogy. systemd is used in many places, from desktops (that POST quickly) to embedded systems where boot time is critical.

If deterministic boot is important then you would specify it explicitly. Relying on emergent behavior for consistent boot order is bad design.

The number of systems that have 5 minute POST times and need deterministic boot is an edge case of an edge case.

A month after that article was published (and shortly after the article was posted on Wikipedia), the Arbitration Committee opened a sua sponte case to review the topic area despite the substance of that article being "Icewhiz was right".[1] It resulted in bans of Icewhiz' enemies for distorting the Holocaust topic area. I think moderators on pretty much any other website would laugh and ignore an article like that as being whining from a user they banned.

I agree that Icewhiz is an Emmanuel Goldstein-like figure at this point who's used by pro-Hamas editors/ultranationalists. A bunch of those pro-Palestinian editors that loved to complain about Icewhiz to deflect from their own behaviour were topic-banned from Israel-Palestine area a few months ago in January.[2]

It's challenging to deal with the Israel-Palestine conflict on any website that allows for user contributions. There's astroturfing and nation-state backed influence operations from probably a dozen countries. I don't think there's any website that has successfully navigated that minefield as well as Wikipedia.

Catalytic converters have to convert a tiny part of the output, and they convert them into more stable forms.

The problem with CO2 is that it's the most stable form.

Also, if you want to absorb the CO2, for 1 pound of fuel you get like 3 pounds of CO2. You can absorb it into a solid and the density is like 3 times the density of the fuel. So with a lot of approximations you need container that has the same volume than the fuel tank to store the CO2, or even bigger if you absorb it in a liquid or much much much bigger as a gas. And you must empty/exchange the container when you refuel. And then you realize that it's better to use an electric car.

I might be seriously mistaken here, but I don't believe being poor in China is better than the US. I mean, at the very outset, you can get "soft-arrested" when you are banned from travel for being in debt. And freedoms aside, there are more in poverty in China then the US.

True, but there is so much value that we provide above and beyond just a cloud bill, that I think it is worth it. This is way more than racking and stacking commodity servers and providing a ssh login.

It is novel equipment that few have ever used before outside of a relatively small HPC community. It regularly breaks and has issues (bugs) that need industry relationships to manage properly. We've had one server down for over a month now cause SMCI can't get their sh/t together to fix it. That's a $250k+ 350lbs paperweight. Good luck to any other small company that wants to negotiate that relationship.

We are offering a very valuable service by enabling easy access to some of the most powerful compute available today. How many people do you think have a good grasp of what it takes to configure rocev2 & 8x400G across a cluster of servers? Good luck trying to hire talent that can set that up, they already have jobs.

The capex / opex / complexity involved with deploying this level of gear is huge and only getting larger as the industry shifts to bigger/better/faster (ie: air cooling is dead). Things are moving so quickly, that equipment you purchased a year ago is now already out of date (H100 -> H200 is a great example). You're going to have to have a pretty impressive depreciation model to deploy this yourself.

I wouldn't just dismiss this as moving costs around.

True! Open source = free stuff for a lot of people. This is why corporations like Microsoft encourage open source - so they can profit off of other programmer's hard work, without giving anything in return in most cases, and in rare cases giving a small donation. So, it goes both ways.

But open source nevertheless contributes to the commons when done well.

Compare and contrast: Free software.

Internal motivation and acting according to your values is not necessarily a good thing. For example, repeat offenders are often internally motivated. They keep committing crime, because they don't fit in. And because their motivations are internal, incentives such as strict punishments have limited effect on their behavior.

Science selects actively against people who react strongly to incentives. The common and incentivized path is not doing science. Competitive sports are the opposite, as they appeal more to externally motivated people. From a scientist's point of view, the honest 99% of cyclists would absolutely dominate the race, as they ride 99% of the miles. Maybe they won't win, but winning is overrated anyway. Just like prestigious awards, vanity journals, and top universities are nice but ultimately not that important.

I love this! Your results seem comparable to the counter strike or minecraft models from a bit ago with massively less compute and data. It's particularly cool that it uses real world data. I've been wanting to do something like this for a while, like capturing a large dataset while backpacking in the cascades :)

I didn't see it in an obvious place on your github, do you have any plans to open source the training code?

> obstructed an arrest by changing standard procedure

Sorry, then would a janitor who puts up a slippery floor sign in front of a door and asks someone to use a different door be "obstructing arrest by changing standard procedure."

This is absurd on its face. You don't have the right to arrest a Judge for "obstructing justice" because they let someone use a different door to leave. And you should think 1 million times of the implication to the rule of law before you do such a thing.

ICE are not gods, and I would hope after this, that Americans would start to consider taking away what power they have, because they are abusing it. And it's threatening our democracy.

> I end up running it dozens of times when changing versions, checking out different branches, chasing dependencies.

Yeah... but neither of that is going to change stuff like the size of a data type, the endianness of the architecture you're running on, or the features / build configuration of some library the project depends on.

Parallelization is a bandaid (although a sorely needed!) IMHO, C/C++ libraries desperately need to develop some sort of standard that doesn't require a full gcc build for each tiny test. I'd envision something like nodejs's package.json, just with more specific information about the build details themselves. And for the stuff like datatype sizes, that should be provided by gcc/llvm in a fast-parseable way so that autotools can pick it up.

Man, you bring up so many good, juicy points. I wish we could sit down and chat about them!

First off, just to be clear, I totally understand the friction points you bring up. APL's learning curve is crazy steep, and learning materials beyond the beginner level are nigh on nonexistent. It sucks, I agree.

That said, if you're able to push through the abyss, I can assure you that most of that friction drops away. It's clear that you're still thinking in terms of individual primitive operations, but with familiarity thing like k v⌿⍨← will just read as atomic operations in the same way that you read "laser" not "l-a-s-e-r".

More than that, though, the if/else struggle you mention really brings back memories. In practice it's really not an issue. We just ⍪←∪ to insert potentially new keys, str←str[x←⍋str] ⋄ k v⊇←⊂x if a sort is needed, etc. But we only do those when the operations on the data demand it. Otherwise there's no point in encoding irrelevant extra structure in the data.

It took me a good couple years of regular APL hacking for things to click, but I'm not really sure how to get across the feeling, so you'll just have to believe me or not, I guess.

> talking about a phone call or a copy

Not really - we're talking about holding someone (and therefore being responsible for their food, safety, possibly healthcare) until the relevant agency collects them.

Even for mere notification, there's nothing obstructive about refusing, even if there was a prior arrangement[0]. Any cooperation would have been voluntary, and the practice and policy of the administration has changed in a way that adversely affects essential city services if they were to continue to cooperate, so that voluntary arrangement would have been terminated.

> _required_

No citizen is required to make themselves known to their state government either. I'm free to go to NYC tomorrow, rent a room for cash, get a metro card, and tell NYS nothing at all, until I earn enough money to necessitate a tax return and have to give them an SSN or ITIN.

Disaster planning etc. is the responsibility of the demographers and statisticians, at least until the the census rolls around, and they're not particularly interested in identity

> expensive

While I threw that in, I do think the cost concerns are secondary to the overall alignment of incentives. Cities have to work for everyone that lives there; without control over the immigration status of their residents (nor any implication that cities _should_ have that control) cities are better off abstaining from questions of immigration status entirely.

"Co-founder" is debatable, but he certainly wasn't "the founder" of the site.

Regardless - whether you choose to describe Sanger's early involvement with Wikipedia as a "founder" or not, 2002 was a long time ago, especially online. The site which he was involved with was very different from the one which exists today.

> As far as anyone could understand, the proposed CMG system wasn't listening through a phone's microphone 24/7, instead it was using those small slivers of voice data that are recorded and uploaded to the cloud in the moments after you activate your voice assistant with a "Hey Google" or "Hey Siri" command.

That's not quite accurate. The CMG thing was very clearly a case of advertising sales people getting over-excited and thinking they could sell vaporware to customers who had bought into the common "your phone listens to you and serves you ads" conspiracy theory. They cut that out the moment it started attracting attention from outside of their potential marks. Here's a rant about that I originally posted as a series of comments elsewhere: https://simonwillison.net/2024/Sep/2/facebook-cmg/

The "Hey Google" / "Hey Siri" thing is a slightly different story. Apple settled a case out of court for $95m where the accusation was that snippets of text around the "Hey Siri" wake word had been recorded on their servers and may have been listened to by employees (or contractors) who were debugging and improving Siri's performance: https://arstechnica.com/tech-policy/2025/01/apple-agrees-to-...

The problem with that lawsuit is that the original argument included anecdotal notes about "eerily accurate targeted ads that appeared after they had just been talking about specific items". By settling, Apple gave even more fuel to those conspiracy theories.

I wrote about this a few months ago: https://simonwillison.net/2025/Jan/2/they-spy-on-you-but-not... - including a note about that general conspiracy theory and how "Convincing people of this is basically impossible. It doesn’t matter how good your argument is, if someone has ever seen an ad that relates to their previous voice conversation they are likely convinced and there’s nothing you can do to talk them out of it."

... all of that said, I 100% agree with the general message of this article - the "truth is more disturbing" bit. Facebook can target you ads spookily well because they have a vast amount of data about you collected by correlating your activity across multiple sources. If they have your email address or phone number they can use that to match up your behaviour from all sorts of other sources. THAT's the creepy thing that people need to understand is happening.
