LangChain co-founder here. There's lots of good feedback here (that also resonates with previous feedback) that we're working hard to address. On some key points:

- We genuinely appreciate all the thoughtful criticism and feedback. Our goal is to make it as easy as possible to build LLM applications (both prototypes and production-ready applications), and if we're falling short in an area we'd much prefer to hear it rather than not. We don't have the bandwidth to respond to all feedback directly, but we do (1) appreciate it, and (2) try to address it as quickly as possible.

- Documentation: we've heard this for a while now, and have been working to improve it. In the past ~3 weeks we've revamped our doc structure, changed the reference guide style, and worked on improving docstrings to some our more popular chains. However, there is a still a lot of ground to cover, and we'll keep on pushing. Feedback on which specific chains/components need better documentation is particularly helpful

- Customizability: we need to make it easy to customize prompts, chains, and agents. We're thinking of changes to more easily enable this - better documentation, more modular components. We'll up the priority of this.

- Other tooling: there are general difficulties in building LLM applications that aren't strictly related to langchain, such as debugging and testing. We're working on building separate tooling to assist with this that we hope to launch soon.
PFAS is a serious concern however and is present.
My MITM proxy that sits on the LAN and acts as a filtering gateway to the Internet still uses a 1kbit RSA key, only because it's the smallest size my devices will accept. It's somewhat amusing that, despite widespread "knowledge" that 1024-bit RSA is "insecure", this is still roughly 2^100 times more difficult to factor than the current latest record of 829 bits.
The same reason you don't go on a drunken gambling traveling adventure on the multitude of credit cards you can get at 25 and then just declare bankruptcy, because now you are going to have a bankruptcy status over your head for the next 7 years and you won't be able to buy a house or get decent rent or get a car loan or even be able to sign up for a cell phone without fronting them the entire cost in cash ahead of time.
It’s not a money issue. These cities have all the money they can into reducing “homelessness” aka open air drug markets. It’s a policy issue. Get these guys off the street and tell them to get clean.
I tried this recently after years of using YNAB. The UX is truly great, but it really doesn’t function as a budgeting app in the way that YNAB does. It’s closer to Mint and I ended up canceling after a week of the trial. A shame because it is very cool looking.
> This is a poor solution to a non-problem. 99% of "private networks" don't need HTTPS for most things, full-stop.

The problem with your security model is that you assume your private network is flawless. Do you really think you can trust every device that connects to your network to be secure? Including your Wi-Fi router? Because I don't, even for devices I personally bought. Even less so in a corporate setting.
The pattern was never specified as fully working. Not in C99 and C90.

It's due to the following reason: it was never specified that realloc(ptr, 0) behaves like free(ptr).

The case of size == 0 is not separately discussed in the C99 description of realloc.

realloc(ptr, 0) can behave like (free(ptr), malloc(0)), where malloc(0) doesn't necessarily behave like ((void *) 0). Malloc may return a unique object that may be later freed.

That is to say, realloc can effectively reduce an object to zero size without freeing it, or possibly even free an object only to replace it with a different, unique zero-sized object.

Note that in the case when ptr == NULL, which is discussed in C99, realloc behaves like malloc. So in the case realloc(NULL, 0), we know that it's the same as malloc(0). That's a case when size == 0, and realloc is required to behave like malloc.

This is a standard-conforming realloc, and always has been:

void *realloc(void *oldptr, size_t newsize)
{
size_t oldsize = __allocated_size(oldptr); // this handles NULL, and returns 0

void *newptr = malloc(newsize);

if (newptr != NULL && oldptr != NULL)
memcpy(newptr, oldptr, min(newsize, oldsize);

return newptr;
}

This realloc will not behave like free if malloc(0) returns unique pointers.

If you want a realloc-like function that behaves like an "all in one allocator", you have to write your own:

void *git_reset_of_allocators(void *oldptr, size_t newsize)
{
if (size == 0) {
free(oldptr);
return NULL;
} else {
// handles all other cases OK
return realloc(oldptr, newsize);
}
}
Singularities are a deficiency in GR, they don't really exist.
This is advancing too quickly.
Ask HN: Getting an Apple Vision Pro to build out the ecosystem
I am a funemployed Silicon Valley software engineer working on some personal projects at this time, living off FAANG savings for a few years. The Apple Vision Pro should come out in <a year and while I do not have interest in buying one for personal use, I am toying with the idea of purchasing one to develop apps.

My theory is that the ecosystem will need to be built out and that developers which participate early in this process will be able to make decent money by selling apps, like we saw with iOS but on a longer timescale due to the high cost of the device. However, it is possible that:

- There will be many more developers contributing software this time.

- AR/VR will fail.

- The device won't actually need many VR/AR-specific apps and users will just use it for existing apps.

The risk is only losing $3,500 though. Is anyone else considering this? Any thoughts on what the early days might be like?
Well, it takes a bit more than that to get into any meaningful distribution.
Of course there isn't anything more dangerous than the government. That is the whole point of a monopoly on force and detention. If done properly it is used to keep people from harming others.

Also, the cell phone in your pocket broadcasts your location a few times a second, and the corporations with that data love working with the government.
This virus feeds on money. As long as there are economic incentives to produce content, people will use generative models to spew it onto the internet. It is undetectable and therefore unstoppable. It will happen regardless of whether OpenAI exists or not.

So if the internet as we know it is dead, what would then inventive be for content farms to keep producing? The internet doesn't run on air, neither do LLMs. It's all very expensive to run. So if the internet does die from enshittification and false / crappy information then it should die pretty soon and then the inventive to produce bullshit content should go away with it. Who is going to pay to host, protect and make available exabytes of nonsense ?

It's wild when you think about what's happened recently. Twitter, for those without a login has just disappeared. Reddit has degraded a lot and my Youtube is so full of actual lies, rubbish and clickbait, I only use it when I really know what I'm looking for, and even then, it's getting really, really hard to find what I want.

What amazes me about YouTube is even people who seemed like fairly respectable YouTubers in the past have jumped on the viral clickbait / false info bandwagon.

I'm with the author, it's exciting but it's also kind of scary, like a fog of confusion is descending on our information space.
Oh, interesting. It looks like they released that in 2021 if my googling is right. Cool.
Do you support geo queries? currently only way to do it in prisma is using raw query?
There are a lot of dumb people in the military. There are also some, usually in special forces, that can run mental laps around most of the people here, then physical laps, then shoot you in the chest from a half a mile away, then give an incredible speech about it all.
Sorry, sounds like my information is out of date as of 2021.
Do AirPods Pro have multiple drivers in each ear to simulate the environment, or is it all just done with head tracking and downmixed to stereo with some snazzy psychoacoustics?
Even Blu Ray isn’t DRM free unfortunately. Hard to own movies at all.
I wouldn't even assume that discrete theories must have a resolution that can be detected.
Cool product!

Can you have special section for audio contents which have transcriptions? That would be very good feature to pay, at least for me.
Are you going to switch back to Mollie?
You can install UTM via AltStore but you’ll be limited to slow battery-hungry emulation. You might be able to use the hypervisor for hardware virtualization support via an exploit like TrollStore running on an older iPadOS. The OS will kill UTM soon after backgrounding to free up memory and preserve battery life so you’ll need to keep it onscreen using Split View or Stage Manager. Overall I found it to be too much of a hassle compared to remote dev using Blink shell or vscode.dev
I don't think position is likely to be discrete, but,

while I also don't really think that angles are discrete, angular momentum *is* discrete, coming in multiples of hbar, the reduced Plank constant.
I would assume it is 0. Once the cert is cross signed, what more bandwidth/computation is there?
Just curious, which ICE car? Unless you're looking at some of the cheapest cars available and also ineligible for the tax credit, I'm surprised the M3 wasn't competitive.
Maybe you want a truck in 2023? Or something with V2L that can power your house for a week?
Having the option of an "older" LTS kernel (say 5.15 or 5.10) would be useful so as to match the kernel used in a lot of commonly used cloud images (including Ubuntu 22.04 LTS and Amazon Linux 2).
What determines the amount of information? Is it the total values the gravity could have had with unlimited mass? The number of values that are less than the one it is observed to be? All the values in the probability distribution for some uncertainty thing?

If you have a carbon atom, does it have unlimited information because it theoretically could instead have been some other number of atoms?
Oh go on.

You really think if Eno released "Ambient 5: Music for Headphones" it wouldn't likely be his biggest seller? "...few musicians..." Eno for sure is one, and it could even be just a different mix and can be right beside the icon for the file with the regular mix on a streaming service. I guess these albums are just that, right? Only not as good.

I'm saying not much at all about Atmos other than Eno is uncharacteristically talking bunk in saying this is what he needs for 3D.
Your first question is the problem: they must always be moving towards the center - which implies they must be getting closer to it. Because if they can never actually reach the center, then in 4D spacetime they're no longer moving towards it - they'd be traveling parallel with it.

Which would imply that singularity isn't a singularity - i.e. the "hole" it makes would in fact be highly curved spacetime in one dimension, but completely flat in another (i.e. it would be a cylinder).

Which creates a hole lot of weird infinities in the system: i.e. a black hole becomes a finite bounded volume on the outside, but contains an infinite amount of space on the inside (since no matter how much you distort spacetime, the molecules of whatever falls in can just pull themselves together more tightly provided the distortion doesn't happen too quickly).

So tell me how BigTech has personally hurt you?

3 reasons

1. it's reasonable to assume the NSA is a decade ahead and has more computers than academia.

2. you want your secrets to last a decade (or longer)

3. the total amount of data you're encrypting per client is only 256 bits anyway (the size of a symmetric key) so the absolute performance impact is relatively minimal
That's what I use in the GPSDO in one of my projects. The internal voltage reference powers a 10bit DAC that we dither to tune the OCXO. If the microcontroller has a voltage rail just for it's internal DAC, that would be the best way to run it. You could drop the opamp and voltage reference from the design and just keep the RC filter.
Grave of a man who never was (2015)
Over here in Seattle, this reminds me--even down to the scrolling javascript stuff--of other features about the "Bertha" digging machine for the I-99 tunnel project, which replaced an earthquake-risk viaduct.

Comparing stats, both project are a similar distance, but the highway involved removing about 23 times more material as it went. (57.5-foot diameter hole vs 12.)
I had a browse of the videos on that channel and was disappointed to find that there was a strong emphasis on unhealthy street/fast food. Ramen and fried rice and hot dogs and artificially coloured candy and such. Disappointing when Japan has so much healthy food and yet I couldn't see a single video showing a kitchen that produces that higher quality food (which I would certainly like to view).
It's a good comparison. I would speculate that it's the target market. If you're buying a Linux laptop you are likely very technical, and know about and want the latest updates. I doubt System76 would get many sales if Pop OS was based on Ubuntu 20.04 and wouldn't get any updates.

However with Android, companies sell 100s of millions of devices to consumers that are more concerned about price point than updates. There just doesn't seem to be the incentive for OEMs to care about it, if the majority of consumers refused to buy devices based on old OS versions or ones that didn't get updates, those devices wouldn't get made.
You will probably get better results using voice2voice models like RVC or Bark, that way the model is on beat for instace. This is how most AI covers of songs are made I believe. It's also easy to train an RVC model and use it on Google colab. Takes about 1-2 hours to train and 16 minute ebook can be generated in about 170 seconds for instance.

Lima has experimental supports for Apple's native virtualization framework, but the default is still QEMU.
Not really. You’d have to make sure you either own the software you ship or that software is already available freely so you don’t get into the space cadet situation like Microsoft Windows.

> Space Cadet Pinball was not originally written by Microsoft, but was rather obtained via licensing from a company then-known as Cinematronics. This means that there are restrictions on what can be done with the program, as spelled out by the license agreement.

https://devblogs.microsoft.com/oldnewthing/20181221-00/?p=10...

The change would be you can’t ship software like this… I would say that is a net positive.

>note the weaselwords. Here's my list:

They're not weasel words, they're how these papers are supposed to be written. These words are more accurate than saying, "this proves," which would be a lie.
Only when sending a one-sentence text, where the beginning and end of the sentence are clearly the bounds of the text itself. You see periods still between sentences of multi-sentence texts. Sometimes other markers are used like ellipsis or emoji.

I really genuinely like this change for orthography. The feel & sound of spoken language is highly sensitive to the context and formality: you talk differently giving a speech than you do at dinner with your family etc. It's cool that we're adapting the written forms to more completely express the full range of formality that we actually produce written language in now.

The details of orthography are all just convention and tradition anyway. As much as it pains prescriptivists and peaked-in-high-school wellactually pedants the true language is the spoken and writing is merely a tool we use to represent it. These additions make writing a more complete & capable representation.

And from a more CS view it's cool too. We've hijacked sometimes-redundant punctuation to convey nuances of tone and intent. Essentially increasing the "bandwidth" of writing.
You can do this with a fair amount of effort. I believe licensing prevents you from shipping those apps directly, though.
We follow a model similar to concourse/governance. Yaml based files decide team and repo memberships. The PRs have to be approved by a group of people and it's dictated with CODEOWNERS file.
I mean no human moderators to break up fights and assure adherence to terms and conditions. Algorithms don't cut it, for me. "Voting" is no substitute, either.
Can't tell if this is sarcasm or not.
Very few governments in the world have an absolute monopoly on violence. Most countries allow some private ownership of weapons, have self defense laws and/or have private security companies. Many countries also allow private mercenary forces that can operate outside their borders.

People like to assume that governments and corporations are inherently incompatible, but that’s just not true. A government is just whichever organization(s) has the most power within a geographical region and a company can very easily become the de facto government in an area if its power is unchecked.

For the most prominent historical example of this look at the East India Government: https://en.m.wikipedia.org/wiki/East_India_Company

From a contemporary perspective there are plenty of examples of large multinationals effectively controlling and directing smaller, less wealthy governments. Even in big countries with strong governments, the influence of large corporations on what laws get passed and how they are enforced can become significant.
Yeah, tbh I was a little shocked he put that out there. Speaking for myself, I know I wouldn't publicly burn a bridge like that for what seems to be no good reason, and I'd advise anyone leaving a job to try to do so on reasonable terms if possible.

If Canonical is really that bad, people already know (and judging by the comments... yeah... not great).
Interesting, then Java is in trouble I guess because it's mostly tied to Spring Boot?
Next you're going to tell me that Austin is in Texas. Austin is absolutely not in Texas. It is surrounded by Texas in almost the same way West Berlin was "in" East Germany.

Maybe more interestingly... Turkey is (and has been for a while) a member of NATO. The last time I was there they were still using the Lira, though it was easy enough to exchange Euros. But there's talk about Turkey joining (I think) the EU as part of the deal for Ukraine to eventually join NATO. So if Turkey joined the EU, would it suddenly be in Europe? My understanding was that Asia started at the Bosphorus, so the majority of Turkey is in Asia Minor.

Not to mention Cyprus is supposed to join the Schengen area at some point. Heck. I don't even know if Cyprus is considered part of "Europe."

I think my point was even geography sometimes avoids simple categorization. And the Britons all seem to be anti-European. So it seems odd Cambridge wants to build the "European Sili Valley" in a country where the majority of those who voted, voted to reject their European association.

I've been pretty frustrated with how private CAs are supported. Your private root CA can be maliciously used to MITM every domain on the Internet, even though you intend to use it for only a couple domain names. Most people forget to set Name Constraints when they create these and many helper tools lack support [1][2]. Worse, browser support for Name Constraints has been slow [3] and support isn't well tracked [4]. Public CAs give you certificate transparency and you can subscribe to events to detect mis-issuance. Some hosted private CAs like AWS's offer logs [5], but DIY setups don't.

Even still, there are a lot of folks happily using private CAs, they aren't the target audience for this initial release.

Couldn’t LIDAR help significantly here?
Sure, but when someone says "your data is encrypted" usually that means it's going to a cloud server somewhere, and that makes me feel the need to ask what the business case is, how is that case opposed to my interest and what would the host do if compelled with a warrant for the data.

It certainly feels wrong for spacetime to be quantized, because it’s fundamentally no linear and geometric in a way that other things aren’t, and quantized theories like string theory tend not to be inherently background independent, which seems really wrong.

At the same time, we know that a basic semiclassical + Everettian model of the world does not correctly model reality - if we run a quantum-linked cavendish experiment, we don’t observe the gravitational effects of superposition. I.e. each branch of a quantum superposition behaves as if it is in its own spacetime. We can even run a Bell experiment linked to gravitational detectors and observe that the results are consistent with gravity being quantized.

Another way to watch and experience steam engines is to go to an "Old Thresher's Reunion/Show". These are often held in rural parts of the U.S., well worth a drive to see these machines in action. Agricultural steam engines were pre-cursors to modern farm tractors, but used as semi-mobile power for other machinery such as threshing machines, saw mills, balers, etc. Wear an N95 and expect to get soot on your clothes.
