What are the use cases of training a model with my own data?

I'd say Apple is even more arrogant, but at least their software is arrogantly functional.

Maybe I could look past this sleep nonsense if their super cool new sleep actually worked. But it just doesn't, instead it cooks your laptop 10% of the time and it you open it up and it's dead.

> Hitchin agrees. “Mathematical research doesn’t operate in a vacuum,” he says. “You don’t sit down and invent a new theory for its own sake. You need to believe that there is something there to be investigated. New ideas have to condense around some notion of reality, or someone’s notion, maybe.”

This is kind of it I think. It's not just physics that drives interesting math, and it's not just recently that this relationship holds. Math is, IM humble O, the ultimate domain-specific language. It's a tool we use to model things, and then often it turns out that the model is interesting in its own right. Trying to model new things (ex. new concepts of reality) yields models that are interesting in new ways, or which recontextualize older models; and and so we need to reorganize, condense, generalize, etc; and so the field develops.
Yup, you're essentially unbalancing the surface area of the planet that gets hit vs that radiates the heat away on the night side. It will decrease the albedo of the planet significantly if it is ever deployed at scale.

Solar panels do this a little bit already, since they're dark and they collect a lot that is reflected back out, turning it into heat by using it.
There's a kids sci-fi novel called The Ear, the Eye, and the Arm that talks about this a bit. There are children searching for plastic in landfills because they've run out of oil to make new plastic. Plastic bowls and things are status symbols because of how expensive plastic becomes.
I came in expecting not to, but I completely agree with this article. I moved off RHEL after using CentOS exclusively for a decade because of the changes in 2023. I loved SELinux, it's a technology you need to sink your teeth into if you want to understand it, but it has decent tooling (like audit2why) and isn't too hard to modify to get working if needed (SELinux booleans are a powerful way to modify base policies without having to recompile).

I do a lot in Kubernetes, and there's been more than one CVE with a line like "Affects all versions of docker/containerd, unless running SELinux," which gave me a lot of reassurance that the effort put into making SELinux work was worth it.

Now that I'm on Debian, I'm slowly building a new set of policies for the OS. Thankfully SELinux has an excellent reference policy[1] to base off of. I'm hoping my new debian base images for my homelab & elsewhere will have a nice restrictive default SELinux policy by the end of the year. I hope there's more community effort here as well, SELinux really can't compare to AppArmor, and is absolutely necessary for proper security.

Honestly I'd love if the wider community took another stab at replacing SELinux with a KSM that had similar functionality but better tooling and design. I'd pick it up in a heartbeat, but right now SELinux is what we have.

I think the plan is to raise a lot of cash and then more and then maybe something comes up that brings us closer to AGI(i.e something better than LLM).
The investors know that AGI is not really the goal but they can’t miss the next trillion dollar company.
If you can't figure it out without the help of an LLM, you're gonna be in a world of hurt in a real world application where you're dealing with a mature codebase and aren't playing with toys you built yourself. Part of being a quality developer is learning how to get unstuck on your own.
Why don't you just not install any apps besides work apps on the ipad?
Yea but I can tell you based on experience that there’s definitely that top tier of people who care about this stuff and comment very thoughtfully that has disappeared from the platform. I routinely see wrong answers or just bad comments bubble up to the top of a thread.
And that amounted to 60 years (and counting) of absolutely nothing in terms of how the physical world works.

Even Witten's achievements objectively reduce to an alternate proof of the positivity energy theorem in GR.

This is an abject failure by all metrics.
Be interesting to know if anyone had any numbers on actual security issues in practise.

Complexity is generally really bad for security. It results in people working around the system or just turning it off. Security is not just "in theory" - a perfectly secure system that most users disable is an insecure system.

It reminds me a bit of the idea of making people change their password every month. Sure, in theory it reduces time a compromised credential can be abused for. In practise though it means nobody can remember their password, people start using really poor passwords and writing them down on post it notes. The net result is much worse security practically speaking, even if its better theoretically.

I always pushed back hard on vendors who wanted me to disable SELinux on my RHEL boxes. It's unacceptable to disable default OS security protections to make an application function. It's no different than demanding an app run as root.

Ask HN: Security risks when buying mini-PCs/PCs from unknown vendors?
I was looking at [Low Cost Mini PCs](https://news.ycombinator.com/item?id=41389931) a few days ago, and saw comments recommending vendors such as Beelink or Minisforum.

These companies are relatively unknown compared to companies like Lenovo, Dell, HP, etc. My guess as a layman would be that that Lenovo is not likely to try and "compromise" the hardware it sells (e.g. with additional chips that are meant to "phone home", or otherwise store data in some retrievable way) because that would damage their reputation and hence their business.

But a relatively unknown vendor might not have such a concern?

So I wonder:

* are my concerns even realistic?

* if so: how does one evaluate security risks that exist when buying PCs from "relatively unknown" vendors?
On-package memory isn't faster. High-end laptops will have Arrow Lake with more cores and the same memory performance but it will be on the motherboard. Desktops should also have good memory performance with CUDIMMs.
Because pretty much everyone on the internet tells you to disable SELinux instead of trying to understand it. I'm always rolling my eyes when I open some deployment instruction for RHEL (clones) and they have as step one: Disable SELinux.

Few will instead read the RHEL provided documentation. Then they could maybe figure out whether there's simply a tunable (getsebool -a) which would enable the desired behavior, or if properly labeling files (semanage fcontext / restorecon) would do it, or even take the steps to add to an existing policy to allow for a specific scenario which somehow was not implemented. Even adding your own policies "from scratch" is certainly doable and provides a great safety net especially for networked applications.

Anyway... we all know disabling security or not implementing it in the first place can really save you a lot of time. At least in the short run.
I paid ~$30 for an electric razor two decades ago. I have to recharge it every 2 weeks. I'm guessing that makes the total cost heading to something like $1/year asymptotically.
Olli Health | New York or Remote (US) | Full-Time | Founding Senior Full Stack SDE | www.ollihomehealth.ai

We are a TechStars NYC '24 startup dedicated to modernizing home healthcare with advanced AI tools and we are growing! This is a pivotal hands-on role that will begin shaping our product from day 1. We recently closed our Seed round from top healthtech and AI-focused VCs investors (Cannage Capital, Arkitekt Ventures, and Tau Ventures) and are using this financing to build a driven engineering team to build incredibly valuable tools.

What we’re looking for:

- Proven success in the fast-paced 0 to 1 early days of young startups (experience on founding team or pre-seed ideally). This is a full stack role in the widest sense - there is devops, a little data engineering, API design, workflow optimization, and frontend feature design. Work can be optimized based on your preferred balance, and what gives you energy, but we need someone who is able to gain confidence in the full stack.

- Experience (5 years+) with most of our stack: AWS, PostgreSQL, Redis, Python (FastAPI), Pytorch, React

- Able to demonstrate hands-on-keyboard coding chops. Role is primarily IC + collaboration with our team, and room to grow into startup leadership.

- Experience working with healthcare data (not required but highly valued)

Comp: $160k-$180k annual FTE base comp + equity package. We cover 100% of Health, Vision, Dental, Life insurance premiums.

I’m Olli's CTO and this position will work directly with me and our core (currently 3-person) engineering team. hiring+hn [] ollihomehealth [] ai - Email me with questions, for a full JD, or to send your CV. Absolutely no staffing or recruiting firms, individuals only.

> My needs are mostly note taking and reading technical PDFs, and for that the reMarkable is fantastic.

I do both of those and I dislike the RM2. There's little space for notes above and below the PDF page, no infinite canvas. I have more space on the back of a printed PDF (to the left of the current text page) than in the RM2. So, all note taking in a PDF for me is just keywords, while I would much prefer to put text and drawing,s graphs, etc. all around the PDF page.

So, for the last few months I have barely used the RM2 and have gone back to pen and paper.

You're in luck, Windows shutdown is now actually hibernate (and has been for a few years). So if you just shutdown your laptop, you've been using this hibernate for a while. Turns out all those people saying "shut down your laptop before you close the lid!" were actually right.
Yeah this was my experience going to Victoria BC. I was surprised that I could buy double-edged blades for my razor in the pharmacy there. Little stuff like that makes me think I belong in Canada more than the US.

This was the result of Philosophers ultimately winning, despite the fact that they are so annoyingly pedantic that we pretend not to care about their work, and also, by ignoring them we can invent iPhones which are really neat.

You can’t prove anything by observation. You can gather evidence through repeat experiment and become reasonably confident as your theory continues to not be incompatible with the observed universe. Then the problem of induction says, “well, it isn’t incompatible with the part of the universe… that you’ve observed, yet!” And then you say, “ok, but I want to use my theory to invent an iPhone, and I think there are enough people in the part of the universe that I’ve already observed. I looked very hard to find evidence against my theory, and I don’t think anyone will find evidence against it before I’ve sold enough iPhones to retire.”

Math, of course, is that stuff which can’t be invalidated by observations. But it is very hard to do enough math to retire off it.
It totally is, in more ways than one.
I don't think Apple let's you completely remove Safari. That in itself is a giant distraction.
They absolutely know about this, given that the seemingly reworked markers for this tablet have a redesigned nib holder that doesn't look like it breaks as easily as the old ones.
This is a common enough issue that there are people on ebay selling caps to replace the broken nib holder, but they seem to expensive for what amounts to a piece of 3D-printed plastic; I might just look into your solution with the lamy pen. It's just a shame that reMarkable is handling those issues so badly. They force you to buy a new pen for $130 because a little piece of broken plastic.

It's always very impressive to me seeing our ability to detect such obscure objects in advance getting better and better. We'll soon have such good detection capabilities that we may start to take these kinds of predictions for granted the same way we take accurate weather forecasts for granted. Can't wait to see the local meteorologist talking about actual meteors.

Man, that's good. I'm a full blown Lenovo apologist, but you cannot catch me dead going to bat for their appreciation of local security. There's a good reason most Thinkpad users entirely wipe the drive they get sent with the machine.

Ah thank you, this is the missing piece! That makes a lot of sense.
I had verified its points myself and I wanted to be honest and cite it instead of pasting or paraphrasing what it said without doing so and therefore plagiarizing.
I never turned off SELinux. There are a few of us out there!
Many have questioned the sanity of those investing in Boom, and from a commercial standpoint I agree. Every time I see the XB-1 I think the real hope is a military purchase, given the XB-1's design choices.

Thus far it looks similar to an upgraded T-38 to me. The XB-1 and T-38 are similar (ish) sizes, have roughly the same takeoff weight, both use the very old/proven J85 engines, etc.

If Boom can pull off the Mach 2+ supercruise concept for this demonstrator, they might well secure a spot as a low cost 5th gen fighter trainer with good export potential as a cheap fighter/recon platform.
Wait, the author is criticizing Debian for not having as heavy-handed a system as SELinux enabled out of the box? That thing that causes so much pain that everyone disables it immediately unless they have fairly extreme security needs?

I remember something similar back in ~2000 - made out of a directv satellite dish.

It was dead simple. Mirror the parabolic surface of a satellite dish, put a hole in the dish, and use an optical sensor to track the beam of light that shone through that hole on the rooftop. Use a couple of motors and an IC to move the dish according to the suns' position.
Just say witch hunt. McCarthy was entirely correct that there were a lot of communists and communist sympathizers, so many that many of the people he thought were helping him were themselves communists or communist sympathizers. Witches on the other hand are not real.
Feels like Anthropic is trying to differentiate from OpenAI by building a small number of high-quality first-party things instead of trying to enable an ecosystem that may be harder to capture value from.

500k context is enormous, but at 3.5 Sonnet prices, also pretty expensive:
$1.50 for one query maxing that out. However, if you use their new prompt caching setup and cache most of the big prompt and are hitting it frequently enough, it's more like 15 cents per query. That's still a lot, but it could produce very valuable results, and sticking the whole thing into the prompt instead of trying to narrow it down first with traditional search lets you skip all the pain of indexing and vector DBs and whatever. This makes prototyping much easier because you can get good results right away by jamming your whole corpus into the prompt, and only then decide whether optimization is worth it.
The plastic cartridges go out of alignment through blade nicks and that sort of thing before they get dull. Running them across old jeans in the opposite direction that they shave will fix it.

What websites spread malware ads? Maybe you should... avoid going to those sites?

It's not the advertisement industry's job to fight malware or to protect you from it, it's their job to get products and services sold. That's called capitalism.

Also, if adblock is a safety measure, why then do these adguard filters and adblockers block ads/trackers on legitimate sites like Google and YouTube?
It's baffling to me that SELinux's UI is like...the best we can apparently do?

The underlying concepts of SELinux aren't so hard but trying to manage it in any sort of coherent way is a nightmare - up to and including the provisions in it for a network based policy server component which just never appeared.

And it sucks! In theory it does so many things we really really want, and should do more. Like I as a user have a great interest in ensuring my home directory files follow sensible markings based on their content - my SSH keys, AWS keys, or banking files all exist in different logical zones of control.

And this is a concept SELinux can handle...but the tools are just so bad at surfacing it.
Furthermore, even if you can write down the math, it might not even be solvable (sometimes provably so) and simulations (or more accurately, numerical analysis and the finite element method) are our only option.
Those people weren’t handed that success. You are acting as if they were born billionaires, which is far from true.

I appear to be in the minority where the RM2 is a perfect fit for my needs - but I can confirm that their support is aggressively anti-customer, and also non-compliant with EU consumer laws.

My device broke in warranty (< 1 year). Customer support refused replacements, finally offering a 2nd-hand / refurbished replacement (illegal according to EU law).

Despite my attempts at polite out-reach to individuals at the company, including C-level, everything was ignored until a lawyer friend sent a formal letter - and suddenly everything was magically resolved the next day.

It's such an expensive device, and each press-release makes it more and more cultish - I couldn't recommend buying this - I'll wait for a competitor to do a better job.
What else would they tell their investors? "We suck at innovation, implementation, execution & delivery combined"?
The biggest per core "efficiency" improvement will come from RDMA, since IO tends to be the largest bottleneck in Redis (and now Valkey). However, if you are running with deep pipelines (sending multiple commands as a batch without waiting for responses from each commands) than the benefits of RDMA are pretty limited since the bottleneck is on command processing. Multithreading doesn't help much either.

One of the strategies that is being used in the multi-threading is using CPU memory prefetching to pull memory closing to the CPU so that we aren't stalling on fetching data from main memory while executing commands. We still want to try to apply these techniques without multi-threading to improve the efficiency of single or double core installations.
Just have to try it to feel the difference :)

The Red Hat model is basically “Embrace, extend, and extinguish”.
The issue is that Visual Studio Debugger used to be good on a few of these features like speed up the watchdog window updating. One of the main benefits of RemedyBG is building a VSD style experience from a decade or two ago. So I don't fully agree with the implication that Linux is just not fully caught up to date with relatively new Windows debuggers -- it has basically never been up to date with debuggers from a decade or two ago.

I should say that I never used to use debuggers until I found ones as fast as VSD was a decade or two ago, and I used to primarily dev in Linux since the mid 2000s.

Edit: a decade or two ago is probably too short. I keep thinking the 90s were 10 years ago :)
Oh, some of those are the _worst_. My wife bought a car, and the dealer had gone beyond the usual decal and license plate holder, and had put an insert in the third brake light.

Intel Arc runs FP16 at 2:1 compared to FP32, and Battlemage on Lunar Lake is the same, and XMX FP16 is actually at 8:1. I don't think M3's GPU has a better ratio.

Of course there are many other aspects, but given it's Intel's latest architecture, which has improved efficiency tremendously (see https://cdrdv2-public.intel.com/824434/2024_Intel_Tech%20Tou... ) it's pretty unlikely M3 has any fundamental advantage.

Do you have any reference showing Neural Engine in M3 supports INT8 (and at 2x FP16? Just curious.)
