Lance dev here. We are working on a new version of our format[1] as well. We are watching Nimble too. If they are interested in solving our use cases then that is less work for us.

At the moment it is not clear that is the case. However, it is too early to tell. Our biggest concerns are:

- Good integration with object storage

- Ability to write multi-modal data without exhausting memory

- Support for fast point-lookups (with the option of cranking up the amount of metadata for richer lookup structures that will be cached in RAM)

Both Nimble and Lance are not intended to replace Parquet/Arrow. Parquet and Arrow are designed to be spread throughout a solution as a universal interchange format. E.g. you will often see them all throughout ETL pipelines so that different components can transfer data (even if it isn't a ton of data). With Arrow and Parquet interoperability is a higher priority than performance (though these formats are fast as well). They are developed slowly, via consensus, as they should be.

Nimble and Lance are designed for "search nodes" / "scan nodes" which are meant to sit in front of a large stockpile of data and access it efficiently. There are typically only a few such components (usually just a single one) in a solution (e.g. the database). Performance is the primary goal (though we do attempt to document things clearly should others wish to learn / build upon). I'd advise anyone building a search node or scan node to make the file format a configurable choice hidden behind some kind of interface.

I do have to worry about privacy (and security) though, I'd be granting access to some random website which doesn't have a terms of service, privacy policy, anything identifiable (e.g. person or company).

Thank you. I find your comment insightful... but I don't think it gives him proper credit for a lot of "boring day-to-day decisions" he's made at Tesla and SpaceX, particularly in operations and manufacturing, over the past two decades. Tesla's early team gives him all credit for ramping up Fremont's Model 3 production in 2019 to ~2.5x what even his execs had said was physically possible. He proved all of them -- and a lot of smart short-sellers -- wrong.
Probably not. It’s a pretty bad article in general.

As for statistics; in the USA around 19% of people suffer from an anxiety disorder.

In the Netherlands, according to an EU study, around 12% of the population had an anxiety disorder.

I do not know if this difference is statistically significant. The Netherlands does have a LOT of unsupervised play, and has the happiest kids year after year.

So it doesn’t seem that unsupervised play leads to extremely different outcomes population wise regarding anxiety?

Of course experiencing anxiety is completely different compared to how you deal with your anxiety, I can imagine there being a bigger effect there?

I stopped trusting the thermals of the Pi after my experiences with the Pi 4. I swapped it in to some projects where a Pi 3 worked great, and the 4 thermal throttled itself the entire time.

Google is misleading people with their advertisements and redirecting users to malicious locations. This has resulted in several hundred intrusions that led to ransomware deployment.

Google is taking a cut in organized crime and malware distribution. How this is "okay" is beyond me.

I am not calling for censorship in any way, and they certainly shouldn't redact/censor results. But, they are running a criminal operation with the displayed advertisements and lying about the location. The average users (especially elderly) are being harmed by Google advertisements.
> A lot of products that seem dumb do end up staying dumb.

Of course, some products will be a success and some will flop, but the successes can only happen so long as someone keeps trying and keeps improving it.

> I really do want electric vehicles to get better

Then you should be happy companies are trying to improve them. This is a good thing that Tesla (and others) are trying to make the semi work. It may eventually result in better outcomes for you, vs the alternative where nobody tries and it is guaranteed that nothing gets better.

Although the comment by comment aspect is new to me, I did see a lot of blatant bot posting/repost karma farming that slid under the table back when I was an active user. I remember several times when I happened to be looking up a post, only to come across posts of the exact same content, exact same text, different account, made months apart and/or on different but related subreddits. Sometimes I'd check the account out of curiosity and find that all of that account's posts were like that.

I think these would be a lot more obvious if Reddit's own integrated search was better.
Keep in mind even the battery in a Model S is half a ton, and integrated into the frame of the car...
That'd work, but then the question is who owns and operates the switch out operation?

Tesla won't want to because they won't want to deal with dead batteries. The trucking companies won't want to because they don't want to deal with dead batteries and the cost to own/operate such specific infra for just their trucks.
I don't think it's melodramatic.

First time I've heard people making that claim was around 2020 in the context of corona iirc. I think they called it "the age of misinformation", and that has only become more relevant since then, so I think it was even more on point then they realized back then.
I've been using Arc on macOS since early on in their beta. I don't think I can go back to other browsers now. For me its a combination of how tabs and pinned tabs are organized along with spaces on the sidebar, along with having a command palette is really really nice. Exited to use this on Windows as well now.
I’ll tick off people by saying the community is in part to blame. Any in-app efforts to monetize are shamed by open source users.

In app monetization campaigns are very effective. Wikipedia pulls > $170m in revenue annually and a big share comes from in-app contribution campaigns.

Let these app developers fund their projects. Companies are already donating dev time. Expecting commercial customers to donate out of “goodwill” will not work.

utf8 is magic.

You can assume US ASCII for lots of very useful text protocols
, like http and Stomp and not care what the variable string bytes mean.

Soooo many software architects don't grok the magic of it.

You can define 8bit parser that check for "a:"(some string)\n

and work with a shit load of human languages.

The company I work for does not realise that most of f the 50 year old legacy C it has is fine with utf8 for all the arbitrary fixed length or \0 terminated strings it stores.

It sounds like you're really upset over this whole thing, which is concerning once you consider how likely Apple is to lose their case here. Are you going to still be okay in the event that Apple is legislated for this behavior? Are you going to protest in the street against the DOJ for ignoring the real problems, like PB&J distribution at the local middle school?
Holy crap.. I stand corrected.
My girlfriend thanks you!
I tried to emulate the math you showed, my Chevrolet Bolt EV emits 96g CO2 per mile when considering upstream emissions on the New Jersey electrical grid, my carbon tax on 96kg emissions per 1000 miles would be $17.76.

Does that sound right to you?
Tesla needs a change of ownership/leadership.

It was fun when I pumped my portfolio with a quick $10K (0dte TSLA put options) when the ceo would say some controversial shit on Twitter (before the leveraged buyout) or smoke weed during after hours with some random podcaster.

But the entertainment is over and the constant news coverage is just spam and reiteration over what we know about this company and its products: very shiny things, but like the CEO’s ego, they are very fragile and have a tendency to be unreliable; or just not live up to the hype.
Good point actually, the article says "late 1990's".. but most things would still work back then. I believe ldd, strace, procfs all existed back then. Python would not, but one could dump environment using perl or some unusual shell.

Keeping dotfiles in version control was be much more rare, so that detection method would not work back then.

But the shell variety was much greater back then, so the worm could end up on server with tcsh or ksh or rsh (the "restricted shell") which would render it inert. And there was a chance of ending up on Solaris box which would just throw errors about wrong architecture and cause immediate discovery.

Also, there were many more shared systems, so granting "sudo" access to everyone was much less frequent back then. And we could have friendly sysadmins examine someone's configs file if they ask for help, which would lead to discovery as well.
It's like Ansible.

That's what I discovered by reading the homepage.
> The whole story is that Europe has made it very difficult for people to start a business, raise capital, innovate and get the reward for taking that risk, so why would anybody?

This has been the elephant in the room in the EU startup world for a while.

For some obscure reason, European regulators are extremely afraid of competition.

The consequence is that if you have a non trivial position (even IC) at some EU startup you will usually be slammed with a few "I own everything you produce and you cannot compete with me for a few years lol" clauses on day 1.

This isn't even something you negotiate, it's something you find out about when you have already left your previous job and companies assume you will put up with it.

Also since the vast majority of jobs pay below 6 figures in EU and it is an increasingly expensive place, saving up a bit of money so you have some runway is easier said than done.
You’re right - I remembered the judgement, which, to heavily paraphrase, basically said “the NEL doesn’t matter if CDL is not allowed, so we only really need to consider that”.

> computervison project in c#

Yeah, for CV applications nuget.org is indeed not particularly great. Very few people are using C# for these things, people typically choose something else like Python and OpenCV.

BTW, same applies to ML libraries, most folks are using Python/Torch/CUDA stack. For that hobby project https://github.com/Const-me/Cgml/ I had to re-implement the entire tech stack in C#/C++/HLSL.
I evaluated the Jetbrains assistant. I was more impressed with its ability to chat about science fiction than actual programming.

It could do some impressive things. I was working on a codebase that used JooQ to generate SQL code. The agent did not have access to the database or SQL scripts but it could figure out what the SQL schema was by looking at the Jooq stubs.

I tried to use it to write a somewhat complex query that involved CTEs in Postgres, there is a chicken-and-egg element of circularity that makes these queries tricky to write. I was able to get it to write very simple JooQ queries but it never really understood the problem I had and solutions and went through quite a few cycles that weren't right even after I'd tell it that "this didn't compile", "that won't work because..." and reading a lot of polite apologizing.

I found it very tiresome to cut and paste code snippets, add imports, have to fix little things, have it not compile, cut and paste compilation errors, then undo all the changes. With close integration to the IDE it might be less painful to cycle through a large number of wrong answers.

My take is that LLMs are very strong when doing things that are basically linear operations from one end to the other end. For instance, language translation is like that, at least at the entry level, since roughly every sentence in one text corresponds to a sentence in the other language. It is like translating JooQ stubs to a SQL script: you don't need to really understand very much, just replace one pattern with another pattern.

Other tasks have an element of looping which is really fundamental in computer science

https://en.wikipedia.org/wiki/Halting_problem

I've found that people often get really offended when you point out that LLMs cannot repeal the fundamentals of computer science, but because they invest a finite computing budget into a problem, an LLM just can't do anything that takes a program which might not complete. The old book

https://en.wikipedia.org/wiki/G%C3%B6del,_Escher,_Bach

has a running story about a conflict between the Tortoise and Achilles who are struggling to solve a problem isomorphic to great logical paradoxes and struggle deliciously for a long time before finally understanding the impossibility of what they are doing. Many people misinterpret this book as a critique of the symbolic AI of the 1970s, but it will give you some insight into how "lets just write a loop with an LLM in it" will get you into problems which are just as intractable as symbolic AI seemed to be the late 1980s.
These competitors all face the same engineering challenges. Why is telsa struggling? Presuming better engineers and a headstart gives an advantage to tesla, ceteris paribus telsa is either ironing out kinks before rushing ahead or simply aiming for a higher quality product.

The original TeX Fonts stored their metrics in TFM (short for TeX font metrics) files, which contains a bytecode interpreter for calculating ligatures and kerning between characters. I learned about that when I tried reading the files myself.

From what I can tell, modern fonts using OpenType just have tables to accomplish something similar now, in the form of the GSUB and GPOS tables?

Documentation for the TFM format here: https://tug.org/TUGboat/Articles/tb02-1/tb02fuchstfm.pdf (search for lig/kern)
This is the most applicable part of the article:

Strategies to improve LLM accuracy:

Retry: We repeatedly invoke a model with the temperature set to zero, up to five times, if it fails the test cases provided with the problem description. Retrying makes sense because LLMs aren’t deterministic even at temperature zero.

Warming: This is the same as the retry strategy, but we gradually increase the temperature of the underlying model with each run, from 0 to 0.5. This increases the stochasticity of the model and, we hope, increases the likelihood that at least one of the retries will succeed.

Escalation: We start with a cheap model (Llama-3 8B) and escalate to more expensive models (GPT-3.5, Llama-3 70B, GPT-4) if we encounter a test case failure.
If it could fix all my CSS problems I'd be impressed.
It's not like they ever stop making old versions (except for the original prototype), there are perfectly valid uses for a Pi 3/4 or even a Pi 2 still today. If you need something more basic, those are good options and far more efficient/reasonably priced too.

The Pi 5 seems to be aimed more at the high end heavily demanding tasks, after all it uses 3x more power than the Pi 4. It's not meant to replace it and it should be equipped accordingly for its role.
and all I'm saying is that it doesn't make it on to the job in the first place usually and it certainly doesn't make it out to the public like with the cybertruck pedal

Chattanooga provides affordable municipal broadband with some of the fastest speeds in the nation.

I wonder if they or anyone else provides a kind of ready-to-go kit for other municipalities who want to copy the best practices.

And maybe municipalities could affiliate with one another and do a joint venture to gain economies of scale.

Doing a federal level handout to major telcos seems like a very corporatist model that is likely wasteful and underwhelming.

The same $6 billion spent by municipalities would likely go a lot further, and would likely be much more sustainable than a system where big companies hold the internet access of poor people hostage in order to receive multi-billion dollar contracts.
techbros thinking they can solve all of the world's problems that they actually have zero experience dealing with?
I mean, it's a matter of pedantics and subjectivity.

Technically, Social Media is a super set of all of those things. They're all media platforms that primarily operate around user socialization (aka engagement). They are, by definition, social media, and in turn social media has been around long before Facebook (eg, slashdot, BBS, Usenet, etc).

I do agree there's a difference/nuance to be recognized here though (eg, old web vs new web social interactions). I think user vs content focus kinda misses the mark, as the truly key differentiator for me is what influences the activity, both in terms of driving people to post in the first place, but also in curating what they can('t) or should(n't) post. In other words, is the platform a community trying to serve it's users, or a company trying to serve it's stake/shareholders?
I personally own one of these, and unless you are running it with a very intense load, it's pretty inaudible. Active cooling on a 35W part is not very loud.
I think EV's (or similar, maybe hydrogen fuel cell, or carbon neutral methane/lpg; direct or used to charge a battery drive train) will eventually make sense for long haul trucking. In the worst case, route times will adjust, and 5 hour routes will turn into 5:30 routes.

However, they really should look for low hanging fruit and then try to expand out from there. Trucks that are stuck in stop-and-go traffic all the time are an obvious candidate (low MPG / high pollution per mile with diesel engines, and those applications have low aerodynamic drag and are a huge opportunity for regenerative braking).

I think commuter / local event busses are another obvious fit. I've started to see these around:

https://www.vanhool.com/en/vehicles/public-transport/battery...

Even though these are replacing rear-engine diesels, some of the components will be common with semis. It'll help bootstrap the large vehicle battery + motor supply chain and fleet management logistics at the very least.

One thing to note is that they're using standard form factors. There's no reason to couple the vehicle layout to changes in the power train.

My guess is that Tesla's trying to replay the luxury -> midrange -> economy playbook that they used to bootstrap the EV supply chain. I don't see how that strategy will work a second time, since the supply chain has already been bootstrapped.
I don’t think the Eu got it right; crucially they missed requiring these choice points to be automatedly navigable for users (eg “.. and if you must publish the metadata representing the choice architecture this way, use these standard keywords to present options, and must allow users to use automation to make their selection “)

The first reg this happens in will I think make billions the world over realize this is what the template of all opt-in online regulation has to be and will hopefully change the world.
