HN TL:DR;

We’re looking for a principal engineer with Ruby/Rails experience to lead the technical implementation of our Canvas-based product for justice-impacted (especially incarcerated) individuals. This role will be focused on technical leadership, but (particularly early on while we are still building the team) will involve hands-on code contributions. Ameelio is a great place to work because the people are great, and the mission is one everybody can get behind. We’re a non-profit (with a good amount of runway) and a very bright future. Come be a part of that future!

Apply at: https://ameelio.breezy.hr/p/272d7d9e67e5-principal-software-...

Note: If you apply, feel free to shoot me an email at ben@ameelio.org to let me know you’ve applied from HN. Please prefix the subject line with “[HN] Principal Engineer: “ so that it properly routes through my filters :-)

Note: The job posting on breezy.hr (where you also apply if interested) has additional information about the role. The rest of this is a GPT 4o-written summary due to HN character limits in comments.

The position offers competitive compensation, a meaningful mission, the ability to shape product development, and a positive work-life balance. Candidates are encouraged to apply through the provided link and notify the hiring contact via email with a specific subject line to ensure proper routing.
Yeah, as a man nobody would believe me either. I was in hospital with acute pancreatitis and they found at the same time I had a fatty liver. Both are often explained by heavy alcohol intake. The truth is I hardly drank at all (I had perhaps had a single bottle of beer in the whole previous 12 months) but nobody would believe me. I ended up being told to never drink alcohol again.
I'm not familiar with the Redis ecosystem. Is this the first open and free (in Apache v2 and controled by the ASF) implementation of Redis search?
The number of "web cron" things in tools like Wordpress and friends is insane; I've been bit a number of times by this - if nobody hit the site for a day, none of the crons would fire.

Maybe I’m mixing Shannon’s limit with the sampling rate imposed by the Nyquist-Shannon Sampling theorem

> Around 2004, Emmanuel Candès, Justin Romberg, Terence Tao, and David Donoho proved that given knowledge about a signal's sparsity, the signal may be reconstructed with even fewer samples than the sampling theorem requires.[4][5] This idea is the basis of compressed sensing

…

> However, if further restrictions are imposed on the signal, then the Nyquist criterion may no longer be a necessary condition.
A non-trivial example of exploiting extra assumptions about the signal is given by the recent field of compressed sensing, which allows for full reconstruction with a sub-Nyquist sampling rate. Specifically, this applies to signals that are sparse (or compressible) in some domain

From: https://en.m.wikipedia.org/wiki/Nyquist%E2%80%93Shannon_samp...
I've built a couple of systems for customers using this, and the development comfort and Flask-like-ness is quite nice.

But it's really just completely dead by now, which is a bummer as this leaves a large complexity gap between this and jumping ahead to just doing full Lambda+CDK/Serverless/Terraform setups.

No they dont,

I needed a new pair of Dr Martens recently,

So I drove to a large shopping centre to buy them.

Got in the shop, asked for some Doc martens size 9.

Low and behold, they dont carry any stock but they can order them online for me and get them delivered.

So I thought I would buy some timberlands instead, so went to the Timberland shop.

Again I asked for a pair of Timberlands my size.

and fuck me. same story. they carry no stock but they can order them online for me and get them delivered.

High street stores have turned into internet shops.

I hate buying online. you see what you want and the price you want to pay, cool. you add it to the basket, then you suddenly see 20% tax added, no mention of that on the previous page. So you think OK, I wont use this shit site again. You relent because what you need is important. so you click through to pay. Then there is the poxy delivery charges.

So your £20 item is now £30-35
Not really. Pantheon, elementary's desktop environment, is forked from gnome. So in that sense, it's very much a traditional linux desktop distro (not to belittle it, as they have put in a lot of worthwhile work into pantheon & the assorted apps)

I'm always happy to see the proliferation of open-source resources for the next generative models. But I strongly suspect that OpenAI and friends are all using copywritten content from the wealth of shadow book repositories available online [1]. Unless open models are doing the same, I doubt they will ever get meaningfully close to the quality of closed-source models.

Related: I also suspect that this is one reason we get so little information about the exact data used to train Meta's Llama models ("open weights" vs "open source").

> at some level, every system is a quantum system

if we consider "quantum" to mean our quantum theory, at the level of general relativity, gravity is not a quantum system. and the qualifier "yet" is also not known.

Show HN: Show HN: Dzero – The fastest globally distributed SQLite database
At JigsawStack.com, we are using Redis by Upstash to store and validate API keys among other datasets for speedy retrieval. As we scaled to more Asian markets and added replicated nodes, the cost started to shoot up while performance got a lot worse.

I discovered hosting SQLite on Fly which was crazy fast & cheap with the full power of a relational database but difficult to use and scale without writing tons of code & devops. Then I found Turso as a managed service which is pretty cool but again got really expensive and had to manage a bunch of replications manually and pay per replications (also not a big fan of the UI, lol).

Eventually, I found Cloudflare D1, which was amazing both cost at scale and performance with Cloudflare edge infra but it stops there, it's very hard to work with D1 out of the box and to scale it for an actual production platform with tons of limits and without getting locked into the Cloudflare ecosystem.

So I built Dzero on top of D1 as a fully managed service that automatically scales globally with over 320 edge locations at no additional cost and can easily be integrated into any platform or framework without getting locked into any ecosystem!

The goal of the dashboard was to be like a Supabase for SQLite, meaning that everything should be easily manageable from the dashboard, from creating tables to editing data!

Right now we are in early access and would love for you to sign up and give it a try! Feedback is always appreciated! We have big plans for Dzero, check out some of our plans on the site!

It's funny that you're repeating my statements on other forms of media sometimes being more appropriate back to me as if I hadn't thought of the possibility, lol.

Better filtering values compression. There are other concerns -- I mentioned them myself -- but compression is orthogonal and significant and TikTok progresses considerably on that front and if you don't see the value in it you're missing out in a big way.
This is of course an anecdote, but I believe my father in law is dead because of the JnJ vaccine that was recalled.
You want something patterned like select. Structure the application around threads blocking on queues and avoiding exceptions entirely makes things far more sane.

SEEKING WORK | Edinburgh, Scotland | REMOTE

Well versed in python and javascript, but capable in other languages as well (have deployed Java/Golang/C/Dart recently). I've recently been working in privacy/security, had a long stint at a global non-profit working on combating disinformation. I've recently been a paid contributor on the open-source project Zulip doing Flutter.

I've been big on python testing lately. I've implemented testing for large python projects at two companies now, bringing them from 0% coverage to 100% coverage. I'm experienced in mocking tools to isolate components for testing, make tests deterministic, and remove the need for networking (who wants to run tests that rely on third party things).

Commonly found using Django but not restricted to that. Lots of experience with modern react/vue as well as Flutter. I've been a remote worker for a decade now, so I had a track record of getting things done without direct supervision, and my remote work means my schedule is flexible for side projects. Set up to easily work with either US or UK entities.

Without looking up what kind of encoding and modulation they are using, I would assume that they are sending a continuous sine wave at the carrier frequency that has the bits - probably after encoding the raw data bits with some error correction code - modulated onto it by changing frequency, amplitude, phase, or a combination of them depending on the value of each bit or group of bits.
i thought this was excellent. very engaging way to quickly learn a useful tool
Yes. High functioning alcoholics are not checking themselves into the emergency room 9 times over a year.
> It does require all of the involved functions to implement support for this, though I think most things do at this point.

Except for reading and writing data from a file using 'os.File', or reading and writing data from a network socket using a 'net.Conn'.

Support for contexts is quite lacking in that the 'io.Writer' and 'io.Reader' interface don't have it, and those are the most important places to have it.

Context also has the problem of waiting for cancellation to complete.

Once you call "cancel()", it async tells a lot of goroutines to teardown, but it's painfully hard to know when they've noticed the cancellation and halted work, which in practice often leads to very subtle data-races.

> [Terminating processes] doesn't handle remote resources cleanly, does it? E.g. if I were to lock a Postgres table for a query, and that query times out, will that correctly unlock the table and close the client? Or e.g. lock files?

Both postgres and file locks will correctly handle cleanup if the process dies (postgres notices the connection is dead and ends the transaction, the kernel releases filesystem locks a process is holding when it terminates).

This is necessary because a process may exit basically at any time for any number of reasons, such as the kernel OOM-killing it.
But those Redis snapshots are only used for regular back-ups, so completely unlike snapshot isolation in a relational database, right?

Reading the section on [synthetic data](https://huggingfacefw-blogpost-fineweb-v1.static.hf.space/di...) was eye-opening for me. The hockey-stick growth of words associated with common ChatGPT output in the common crawl database over the past ~18 months is worrying.
Heck yes. Been using systemd-boot for years, even before Debian integration has the necessary kernel hooks, and it's just so much better so much simpler than grub. This is a humble but great first step to help get this great alternative into use!

What is your suggested approach when there is no (reliable) scientific evidence for any course of action and not enough time to gather such (reliable) evidence? Note that not taking any action is also a decision that, in your framework, requires supporting evidence.
In theory you can do code-based CAD with FreeCAD, but it's going to be more verbose than OpenSCAD and I haven't come across anyone doing that in anger.
The part about the troops isn't relevant given that it's a story about a civilian militia and troops is a reference to a professional army. Still, it looks like you're right about the recruiting. This was written seven years ago, guess I didn't spot the quote about their growth. I'll remove that story and add a note to the bottom. There will still be 15 examples which is plenty to make the point, especially as that's the least important example.

> I still trust more traditional journalists than you

By all means, trust who you want! But bear in mind you could easily check these examples because there are links and sources for everything, something journalists often don't provide. For example, the Reuters story in the parent post about "Peace Data" doesn't seem to have any links at all.
Again, to me, "more range" as a result of a bigger battery is a negative.

And just out of curiosity, I compared local pricing (CAD) - a Kona starts $47k after rebates and incentives and an MX-30 starts at $39k, so pretty hefty difference. For that matter, even the Leaf starts at $42k.

As for the Leaf, I wouldn't consider an EV without active cooling on the batteries unless the manufacturer included a lifetime battery warranty.
You bet. Mushrooms pop up so quick after a rainstorm because what you can see is just a tiny percent of the mass underground. It's like you growing a pimple.
Field theorists pretty much already have abandoned the vector calculus version of the equations, though.
Pretty cool, multiple level IS is great. Does KQIR support predicate pushdown?
Looks cool.

What is the benefit of registering? I skipped it to try it out.

Was very quick looking at my local MySql database. I liked being able to run sql against some local parquet files.

Would need to support Redshift via an ssh tunnel for me to use it on a regular basis. I don't want to manage the tunnel with a different tool.
> Who decided that OK/Cancel made better answers to boolean questions than simply Yes/No?

No one did. It's programmers choosing the wrong MessageBox options, and other programmers following bad examples.

Plenty are doing it right (even though I can't name them right now)
I don't think GP's statement was that all code everywhere must be perfect.

Just that code which is designed to be run in a separate process with the express intent of allowing termination at timeout should also be designed to not change state outside of itself. If somehow it really needs to (e.g. a 1TB working file), either that process or its invoker needs to have cleanup code that assumes processes have been terminated.

Doesn't mean that ALL code needs to be perfect, or even that this code will be, just that a thoughtful design will at least create the requirements and tests that make this model work.
I think there’s one flaw in the overall theory presented in the article: it was demand for coal for heating independent of the industrial revolution that really kickstarted things and the labor exploited for coal mining was the lowest of the socioeconomic classes. Before the industrial revolution England was already mining around five times more coal than the rest of the world combined just to survive winters. Once they exhausted the easy surface deposits they had to go deeper and deeper which required mechanized power to work against the water seeping in. The first engines were invented not when labor became too expensive but when it was impossible to do with human labor at all.

After reading Coal - A Human History I’m of the opinion that the industrial revolution was a complete accident of circumstance on a tiny island that didn’t have enough trees to support its population’s energy needs and a surface supply of coal just big enough to get the industry started but not enough to supply the growing population without digging deeper.
Very nice! Now if it could just support offline use like the .qwk readers from the BBS days.

Ogma: Interpretable Symbolic General Problem-Solving Model
Exactly. If we had kept funding NASA up to now, at the levels that reached the Moon, we would be mining asteroids by now. Instead, once the space race was one, there was no purpose so funding was cut. That we do anything with such meager funding is incredible. Imagine if we had vast solar arrays, bases on multiple planets. It is totally doable with current technology, just a matter of funding.

Thought, guess that is the point of this article. There is no demand.
