In 2011 and 2012 in between jobs I wrote a few bits of software, of which

- one was a SQLite3-based, all-SQL reimplementation of a subset of UName*It (an object-oriented database from the 90s meant for storing NIS/DNS/etc. data)

- another was an RCU-like lock-less, very fast user-space data structure written in C, born of frustration with read-write locks in Solaris

Of those the latter ended up being useful to me about 5 years later, and I still use it in production, though I originally wrote it for myself.

The problematic part wasn't handling Negotiate w/ GSSAPI on server side, it was handling Negotiate w/ GSSAPI on client side.

On keycloak side, it took a small configuration change (provide it with keytab, pretty much). By also using OIDC with Keycloak, I could ensure that access based on LDAP group membership was checked before accessing the application.

Yeah, I think you're right.

I think you could build such an API, but there will be so many gotchyas with each special form of payment, it will be really difficult to use well. Knowing which fields to populate for a given form of payments starts getting more complicated, and dealing with the odd side-effects of each also start to multiply.

Oh, the irony.

A few years ago I implemented a top to bottom ISO27k1 ISMS for a client handling extremely sensitive and mission-critical data for industry.

One risk I recommended controls for was that of a fire and/or flood at their primary datacentre for their client-facing offerings - this datacentre. I’ve experienced the misery of a datacentre oops myself, firsthand, twice, and it’s a genuine risk that has to be mitigated.

At my insistence, I had them burn hundreds of man-hours ensuring that they could failover to a new environment in a different datacentre with a bare minimum of fuss, as what I arrived to was an all the eggs in one basket situation. It took a fair bit of re-engineering of how deployments worked, how data was replicated, how the environment was configured - but they got there, and the ISMS was put into operation, and was audited cleanly by a reputable auditor, and everyone lived happily ever after.

Except… they were acquired by private equity. Who had no truck with all of this costly prancing about with consultants and systems. Risk register? Why do we need this? What value does it add today? ISO27k1? Don’t be silly. We have that certificate. You don’t need it. Dev team, ops team, leadership — almost everyone — ejected and replaced with a few support staff.

I see their sites are down.
Yup. I expected this to be a “we’re shutting down, thanks for all the fish” type message. And it sounds like if not for the astronomical raises they did in the good times that’s what it would be. They’ve been hemorrhaging users since Dec 2020.
I just want to say that it's a shame you're being severely downvoted.

Because this is a serious question whose answer is extremely non-obvious. Is this a market failure or not? If so, what kind? Is this a very unique market failure that needs specific legislation to address in farm equipment specifically, or is it generalizable to certain conditions that future legislation might target to benefit more people? If so, what are those conditions?

I think we can defend right-to-repair, and at the same time ask the serious questions about why we need legislation around it at all, why it hasn't happened on its own?

It’s pretty clearly a way to allow the artist (or their heirs, in the event of their passing) to benefit from their works being labeled Valuable long after they parted with it for a commodity price, instead of solely profiting some “art investor”. The exact opposite of serving the smarmy capitalist class that your label of “rent seeking” conjures.

> Now I'm wondering if Fermat's Last Theorem has a bitwise analogue.

It hasn’t in this sense. The ^n operator flips the ‘one’ bits in n in its argument, so for any n, we have

a = a^n^n

So, for all a and b,

a^n + b^n = ((a^n + b^n)^n)^n

that makes

c = (a^n + b^n)^n

a solution to

a^n + b^n = c^n

and that means we can find a c for every n, a and b.

Vice Media has several issues;

1) The founder, Shane Smith, was over ambitious and raised over $1 billion, which is just too much for a media firm. This is not a software business with high margins to justify such capital.

2) Vice transformed from an edgy content company producing cool stuff like a documentary about the Liberian cannibal warlord and a trip to North Korean labor camp and became just another mainstream liberal/left-leaning news outlet; the problem is there’s no shortage of such outlets, so Vice lost what made it unique.

The good thing about the kind of edgy content Vice produced is that it cut across all political spectrums and across different countries, meaning a larger audience. Anecdote is I and my friends (from Nigeria) used to watch Vice shows but have stopped due to shoving US politics down our throats.

What will likely happen is that Vice will end up selling for scraps. But note that Shane Smith already sold $100 million+ worth of shares [1], so he’ll be fine regardless.

What makes Gensler so confident he's going to succeed where others have failed? China banned crypto a few times. Evidently, it's still not banned enough to stop people from using it.[1]

This isn't the first time a government has tried to squash cryptocurrencies. For most of the people interested in the technology, this is just another mile marker on a 10+ year long journey. I'll place my bets on the cryptocurrency folks. After all, they have more experience subverting far more totalitarian regimes than the power-hungry bureaucrats at the SEC understand.

This crusade against crypto feels like the DEA's war on drugs: to perpetuate the existence of a self-licking ice cream cone.

The reason to pick up a "a full 3D rendering library" is that it is actually a lower level interface to the hardware. Almost all 2D operations are now implemented on top of 3D hardware primitives.

By limiting yourself to a 2D engine you're ensuring there are more layers of abstraction between you and the hardware. While # layers of abstraction doesn't always correlate with overhead, it does place limits on performance.

They have completely different data models though, XTDB is a schemaless document data store, think mongodb but with SQL/Datalog querying and bi-temporality.

Datomic's data model is something they call the 'universal schema' where you just specify the attributes and then create entities however you like from them. Datomic aligns more with how you structure data in Clojure, avoiding the impedance mismatch.

That would still allow the exhaust to run along the ground far beyond the OLM. He could erect some berms covered in concrete at a some distance from the OLM to avoid damage from that.
The rider could have changed their destination in the app. Or Lyft could have swapped drivers and then the other driver canceled. Or the driver’s phone could have gone offline without him noticing due to bad cell reception. Or about a million other reasons - I don’t know the specific circumstances so it’s hard to say.

Driver switching has been happening for years though, way before I saw priority pickup as a rider.

I think it's mostly transmissions and other non-turbo effects that cause these contemporary lag complaints.

With all the fleet mileage requirements, there are much higher gear ratios for cruise and coast modes, so the engine can be bogged way down near idle speeds. Also, there are more software based throttle controls and interlocks. Some of this has to do with heavy-handed reaction to prior "unintended acceleration" panics, and some is just part of all the modern traction/stability control and efficiency programming.

The programming can get utterly confused and fail to dip back into a ground state where it is ready to accelerate. People doing various combinations of heel-and-toe or other transitions between braking and acceleration, including rolling stops, may get their car into a different mode than they would want, and the recovery from this seems like "turbo lag" or worse.

This is super helpful. I'm building a document question-answering service over a custom data corpus (related to Saivism, a sect of Hinduism). So far the first pass has been to manually chunk the text (based on headings, chapters etc.) and then I've used OpenAI's embedding service and storing the embeddings in Pinecone. All stiched together using LangChain. To ask a question, the question is again embedded, then searched against the vector store, then the related documents are provided as context to the LLM along with the question.

So far it was really easy to set up the prototype, but the results weren't as great as I had hoped, so I'm excited to see how I could improve it.

Edit: wow, I didn't see this before. LangChain implements one of the featured article's suggestions (HyDE) - https://python.langchain.com/en/latest/modules/chains/index_...

I think you're right about prompts getting "easier" but I don't think it's a good thing. I expect it will evolve like google search. Where initially there are ways to increase specificity, or at least introduce enough randomness to get some different results, it will converge to something that ignores most of what you prompt and gives you what OpenAI wants you to see. That's really the only way adapting to "bad" prompts even could work

I feel the same frustration. I work in a field with stupendously tight latency constraints and am shocked by the disparity vs how much work we fit into tiny deadlines, vs how horrifyingly slow gui software written by well resourced mega corporations is.

It feels to me like user interfaces are somehow not considered high-performance applications because they aren't doing super-high-throughput stuff, they're "just a gui", they're running on a phone, etc. All of that is true but it misses that guis are latency/determinism sensitive applications.

I remember hearing some quote about how Apple was the only software company that systematically measured response time on their GUIs, and I'd believe it because my apple products are by far the snappiest and most responsive computing devices I have (the only thing that even competes is a very beefy desktop).
