On an ordinary morning I get up at 7:30 often I don't want to eat much, I drink a cup of tea, take medicine, pack my bags, then get to the bus stop at 8:20. Often I get a coffee and maybe some food at the cafe and I'm at the office at 9.

Show HN: HN Karma Tracker Using GitHub Actions
Hi HN! I built a simple tool that automatically tracks and visualizes your HN karma over time using GitHub Actions.

How it works:
- Uses GitHub Actions to fetch karma data daily
- Stores historical data in JSON format
- Generates visualization with trend analysis using seaborn
- Self-hosted: Fork the repo and add your HN username as a secret

Technical details:
- Written in Python
- Automated with GitHub Actions workflow
- Data persistence through Git commits
- Visualization includes moving averages and trend lines

Quick start:
1. Fork the repo
2. Add HN_USER_ID secret
3. Enable GitHub Actions
4. Get daily karma updates and visualizations

Repository: https://github.com/nkkko/hn-karma-tracker

I built this to track my karma growth over time and learn more about GitHub Actions automation. Would love feedback on making it more useful!
How do obelisks fit in with commonly known forms of life?

We all understand cells/bacteria and their interaction with viruses: Viruses infect cells and make them into virus factories…

What do obelisks do? Are they integrated / read by DNA machinery/organells into cells that then produce more obelisks?

What‘s their life cycle?

How are they different from alread known viroids?
I’m actually glad to hear that! I guess my underlying concern is that not knowing the full breadth of modern iOS’ attack surface might make me complacent when evaluating whether there are any risks that Lockdown doesn’t cover, and that being constantly notified on updates might somewhat alleviate that.
It's called a PE in the US. But, for software, it was discontinued because it wasn't really used. And, indeed, it's pretty uncommon for most engineering disciplines except those interacting with regulators--civil engineers in particular.

But it comes with requirements like 4-year degrees, having worked under a PE, etc.
Le ebil national populism. LOL. Talk about non-sequiturs.
> Additionally, some of the 112 that did have a victim didn't even happen on campus. See this linked incident.

Did you look at your link?

> Student shot in leg during dispute in parking lot as school was dismissing

That's a school shooting. The parking lot is absolutely part of the campus.
The way this works is awesome. If I understand correctly, it's like that, given (part of) a sentence, the next token really in the sequence will be one predicted by the model among the top scoring ones, so most next tokens can be mapped to very low numbers (0 if the actual next token it's the best token in the LLM prediction, 1 if it is the second best, ...). This small numbers can be encoded very efficiently using trivial old techniques. And boom: done.

So for instance:

> In my pasta I put a lot of [cheese]

LLM top N tokens for "In my pasta I put a lot of" will be [0:tomato, 1:cheese, 2:oil]

The real next token is "cheese" so I'll store "1".

Well, this is neat, but also very computationally expensive :D So for my small ESP32 LoRa devices I used this: https://github.com/antirez/smaz2

It changes depending on season, right now its winter where I am.

Wake up and go to the garage to warm up the gym - the average temp is around 20F in the AM so it takes ~40 minutes to get to a comfortable temperature.

Make coffee, let dogs out, take meds and supps. Im making a serious effort to step away from social media so ill listen to NPR instead while thinking about what I need to do that day or knocking out quick chores. I dont eat breakfast on workdays.

Train for 1-2 hours.

My first work meeting starts around 9-930.

On the weekends or holidays my spouse and I cook breakfast together and talk.
It's certainly one of the few things that actually gets their attention. But aren't there more important things than this for the Luigis among us?

I would suspect there's good money in offering a service to detect AI content on all of these forums and reject it. That will then be used as training data to refine them which gives such a service infinite sustainability.
Agents, LLM Evals, OpenTelemetry – Lessons from Building Arize Phoenix in 2024
We're the team behind Arize Phoenix, an open-source LLM observability tool that we launched last year.

This past year, we watched the AI industry shift incredibly quickly. Agents became the new norm, LLM evaluation went from a niche interest to a product requirement, and OpenTelemetry became the LLM observability standard. And somewhere in the middle of all that, our open-source project went from 20k monthly downloads to 2.5M.

Along the way, we learned a ton: what it takes to adapt OpenTelemetry for LLM observability, why agents need better evaluation frameworks than existing function calling evals and skill checks, and how to effectively combine synthetic and non-synthetic data for evaluations. It wasn't always smooth sailing, but figuring it out felt like we were doing our small part in moving the whole space forward.

The support from the community has fueled our ability to double down on development. We wrapped up 2024 with major launches like Prompt Playground and Sessions, and we have a ton more on the horizon.

Check out our full reflection here for more: https://arize.com/blog/arize-phoenix-2024-in-review/

And finally, a big thank you to everyone who's tried out Arize Phoenix, left comments, submitted issues, and come to meet ups. We, quite literally, couldn't do it without you!

I'm not sure which side you're arguing for, but I do agree with what I think I'm reading - that you should be able to tell the table what you are and aren't comfortable with. And the new rules encourage that.
Why not? Seems like there’d be a lot of use cases for it. Think small take-out only ghost kitchen setups.
The process you describe above is highly vulnerable as Ponzi scheme. The goal would be to raise total revenues, to paint a certain financial picture to meet targets for cashing out before the high debt load and interest payments sink the ship.

As soon as there is insufficient cashflow for several consecutive periods, the whole thing comes crashing down. This is a strategy for cashing out, rather than building a long term sustainable book of companies for steady, organic growth which has the cash to payout dividends and reward loyal investors.
Anyone have experience with NimBLE (the mentioned open source BLE implementation https://github.com/apache/mynewt-nimble ), how it compares to nordics implementation?
The payment model probably isn't the biggest problem with the US system.

My belief is that it's the relatively complicated regulation of capacity (federal and state regulations on facilities and providers), which pairs poorly with government programs that increase access to care with direct subsidies.

We should train lots more providers and eliminate barriers to entry (so for instance, if someone wants to open an MRI suite, let them).

Up anywhere from 6 (well, poop) to 8 (yes!). Wander into kitchen, turn on coffee maker, take out mouth guard, swap out yesterday's cup for a clean one, make sure cup is right side up, hit the double espresso sequence (paying close attention because the x2 button is too close to the power button for my stunned, spastic, uncaffeinated mind and fingers), pee, take coffee and phone to garage, smoke as little as possible, head to living room, finish coffee while playing word games (dordle, wordle, the mini, zorse, octordle, hurdle), check HN, various news sites, poop, have first breakfast, greet dog of joy, wipe him down, feed him, walk him (20 minutes if I have meetings or other reasons to get home sooner, an hour or more otherwise, unless it is so cold he cuts it short (anything under -15C and the odds of that are even; -30C and might turn around at the end of the driveway)), have second breakfast.

Now the day can begin.
What makes you think it will get popular? Android has had it forever and almost nobody uses it.

Regarding lossless text compression, does anyone know how a simple way to compress repetitive JSON(B) data in a regular Postgres table? Ideally I would use columnar compression [1], but I'm limited to the extensions supported by Google Cloud SQL [2].

Since my JSON(B) data is fairly repetitive, my bet would be to store some sort of JSON schema in a parent table. I'm storing the response body from a API call to a third-party API, so normalizing it by hand is probably out of the question.

I wonder if Avro can be helpful for storing the JSON schema. Even if I had to create custom PL/SQL functions for my top 10 JSON schemas it would be ok, since the data is growing very quickly and I imagine it could be compressed at least 10x compared to regular JSON or JSONB columns.

I don't think anyone is talking about "fetch, decode, operate, retire" pipelining (though that is certainly called pipelinig): only pipelining within the execution of a instruction that takes multiple cycles just to execute (i.e., latency from input-ready to output-ready).

Pipelining in stages like fetch and decode are mostly hidden in these small benchmarks, but are visible when there are branch misprediction, other types of flushes, I$ misses and so on.
When my evil twin was out one summer I would get up with the sun and walk maybe 6 miles in the woods and still start work at 9am. Then I'd go home and walk another 6 miles before sunset. And go the gym in the middle of the day and some evenings too.
After reading 1/2 of the article, I still have no idea what a passkey is.
Flammable vs Inflammable: What Is the Difference?
Are we taling savvy users or regular users?

Regular users would not set up double passkeys, and would suffer vendor lock. They would be better off with password manager instead.

Savvy users know how to follow password hygiene, and have no need to have it enforced on them. So they don't need passkeys either, they would be better of with good password manager.
If you look at the table and do the math to convert obfuscated units, a 3/4 ounce serving of “whole grains” may have 5g of added sugar, which is 5/21.26 g or 23.5% added sugar.

This seems like an obvious problem to me. Despite some progress with adding nuts and salmon.
Show HN: An otherworldly 3D scene in 16 kB of JavaScript
(trigger warning: I know HN isn't keen on anything related to crypto, and this is crypto-art.)

Over the course of a couple of months this year I learned path tracing, signed distance fields, GLSL coding, and compacting JavaScript using a coding style you should never use in real life. But this all resulted in a system that can create "photo-realistic" 3D images of an otherworldly scene in 16000 bytes, no dependencies.

Monte Carlo path tracing is a very interesting technique, albeit very slow to render. It still amazes me how you can get a huge amount of variation and realistic lighting from a tiny amount of code that basically simulates millions of light rays bouncing around in a mathematically defined scene with some randomness applied.

You don't think a tool saving 10% of your time is worth learning to use?!

Anyway, this gets off-track. The metric is (time wasted on problems that only exist without typing) / (time it takes to configure TypeScript). Regardless of what your 10% figure is, learning TypeScript and configuring it for a project takes less time.

> If you're prone to making easy to avoid errors in your code, then maybe Typescript will save you time. For me, that is not the case. YMMV.

Putting aside the dig, it sounds like you're working alone, so use whatever you want. It matters a lot less when you control the data structures and hold the entire program in your own head.
Some of them are rechargeable, but you'll only cycle the battery 2-3 times before the juice is gone.

> Mexicans have guns.

Mexico has some of the most stringent gun laws in the world. They also have more than four times the murder rate of the US. So while it's technically true that Mexicans have guns, this is more along the lines of "people inclined to violate the law against murder have no qualms about violating the law against unlawful possession of a firearm" rather than that it's easy to lawfully acquire a firearm in Mexico.
Right? It took me a year and a half to find a GP accepting new patients and get my first appointment. I’m in the US. Getting pre approvals and appealing denials has delayed my care multiple times in other situations.

Amazon has a diversity team in the entertainment side of business that literally changes casting and content to fit their DEI goals. It often happens in awkward and forced ways, and that is affecting things like this Bond controversy. Most of this is motivated simply by Amazon’s own DEI culture. But part of it is because the award shows have criteria for eligibility (for best picture etc) that require meeting diversity and other requirements that have nothing to do with how entertaining the show is. Since those creating or participating in these shows don’t want to be ineligible, they do whatever it takes, including retconning.

True. You can imagine how difficult it is for the hardware engineer designing and testing these things before production!
That's true, but then, I'm not saying that the Quest is an offline-only device without cloud features. I'm saying that Meta didn't invest $63 billion just to create a "suction pipe for hoovering up that data". They have much bigger ambitions than that.

So, to be clear, the GP was stating that their issue is a lack of free speech. You agree that that’s your biggest issue with Bluesky too.

But you’re unhappy with people expressing their personal opinions, primarily because you don’t agree with them?

What version of free-speech is it that you want? I assume it’s just like all ‘free speech absolutioniats’: free speech as long as it’s your own or from people you agree with.
> UK system is collapsing under underfunding and misallocation

Fifteen years with the "let's privatize everything!" party will do that, yes.
> SQLite does not have a Code of Conduct (CoC), rather Code of Ethics

There was confusion over this, because of different usage of words. Simplifying well beyond the point of strict accuracy, a CoC is a weapon to bind and control external contributors’ behaviour, the CoE is SQLite developers declaring their intended conduct towards others.

> SQLite is pronounced as “Ess-Cue-El-Lite”.

This doesn’t match the quote that follows, which says “S-Q-L-ite, like a mineral”. And that’s just how one guy chooses to pronounce it… I wonder how many others do; certainly I’ve never heard it.
> During this time I hopefully remember to take my medication.

I have a recurring reminder on my phone and find that it helps keep me on track for this.

I'm not used to taking medicine and only started a couple months ago, so found that I can easily forget without it.
I think this should have moved faster, but there's no way this is a single days work.

Especially since a large part of the required work is meta work to show that they worked "properly".

There are executive orders (and maybe laws? can't remember) that require all rule making to be subject to thorough cost benefit analysis.

One of the required actions between a proposed and final rule is to review, reply to, and perhaps amend rules based on comments. The final report indicates 400 comments, and includes responses to basically all of them.
Are these IPs actually from OpenAI/etc. (https://openai.com/gptbot.json), or is it possibly something else masquerading as these bots? The real GPTBot/Amazonbot/etc. claim to obey robots.txt, and switching to a non-bot UA string seems extra questionable behaviour.
> Do magnified long-distance movies shot with normal focal-length lenses look like their telephoto equivalents?

Generally, I think the answer is yes. But the more complicated answer is that every lens design has its own flavor of distortion. An image from a lens optimized for telephoto shots is going to have slightly different characteristics than a cropped image from a lens optimized for wide shots.

The compressed effect I think you are referring to is likely attributable to perspective, most noticeable when the movie does one of those zoom shots where they keep the subject at the same relative size in the frame while moving the camera in or out. Like on this shot: https://youtu.be/in_mAvHu9E4?t=19
At a bigger company, they need to more or less go through the motions even if the top person has basically made a decision after a chat and they're writing a job description for you.

At a small company, a chat over lunch that you didn't even go into thinking of it as interview may be enough.

Ask me how I know in both cases :-)
I assume it's like Nigerian Prince emails - if they were believable, they might have appealed to buyers who would have done something like purchasing one and testing it, instead of spending millions of dollars on garbage.

This is not everybody's (all over the world I mean) experience over last 50 years. In some places, poor people become much richer than before.

Now, everybody should be worried if this can't happen anymore, but I think that, for now, there are still options for people (ok, if you don't live in a state like North Korea, but they are probably more the exception than the rule).

I think HN User potato3732842's comment was probably true back in the 90's.

But now, yes, the nature of threats to US citizens have changed. There has obviously been a decrease in the whole drug and gang violence side because of interdiction and enforcement. Meanwhile a massive expansion of the whole "school or workplace shooter" thing. Law enforcement has not changed to effectively meet this threat yet, so it seems like it's happening with impunity. Just as in the 90's law enforcement had not changed to meet the drug violence threat yet, so drug violence seemed like it happened with impunity back then.

We just need for law enforcement to increase the pace at which they adapt to meet new threats.
Isn't that happening anyway? New stations will be designed to interface with current spacecraft, that are designed to interface with current space stations.
