HN! I'm the author.

Spark is the first step in a larger project I'm building called VeloroLABS.

The Problem: The Cyberdeck scene right now is amazing but purely hardware-focused. It runs on enthusiasm, glue code, and disjointed scripts. There is no unified "Edge OS" or software ecosystem designed specifically for these portable, hacked-together rigs.

The Vision: I want to fix this by building both the Software (tools like Spark) and eventually the Hardware (budget-friendly, modular cyberdecks). My goal is to make cyberdecks a legitimate, productive platform, not just a Reddit aesthetic.

Spark fits in by solving the "how do I ship code to this thing?" problem. It turns any device into a deployment target without needing Kubernetes or heavy runtimes.

Tech stack:

Rust (Tokio, Axum)
Custom binary protocol over TLS
UDP auto-discovery (zero-config networking)
Built-in reverse proxy (no Nginx needed)
I'm 18 and doing this parallel to university. Feedback on the architecture (or the vision) is highly appreciated!
Show HN: Do you think this is the best diffchecker and would you switch?

Hi HN

I built diffchecker.dev, a simple online diff checker for comparing text/code quickly in the browser.

I wanted something that is:

Fast (no signup, no clutter)
Privacy-friendly (diff happens client-side)
Useful for everyday developer workflows

https://diffchecker.dev

I’d really appreciate honest feedback:

Do you find the UI intuitive?
Is anything confusing or missing?

Happy to iterate based on feedback.

Thanks in advance.

That story says a lot about where the gaps really are. Most doctors aren’t lacking raw intelligence, they’re just crushed for time and constrained by whatever diagnostic playbook their clinic rewards. A chatbot isn’t magic insight, it’s just the only “colleague” people can brainstorm with for as long as they need. In your uncle’s case it nudged the GP out of autopilot and back into actual differential diagnosis. I’d love a world where physicians get protected time and incentives to do that kind of broader reasoning without a patient having to show up with a print‑out from Gemini, but until then these tools are becoming the second opinion patients can actually obtain.

The linked article (<https://www.spacemit.com/news/%e8%bf%9b%e8%bf%ad%e6%97%b6%e7...>, in Chinese however) is definitely worth reading. Glad to have so much to learn about instruction selection!

> if it’s just you on a server in your garage, then there would be no advantage to either you or to the ecosystem for PyPI to federate with your server.

Why not leave decision on what providers to trust to users, instead of having a centrally managed global allowlist at the registry? Why should he registry admin be the one to decide who is fit to publish for each and all packages?

Those science studies are a load of bull if they say added sugar up to 50 GRAMS has no effect on your health. Your gut develops a craving for it like no other and your insulin spikes much harder when you intake that much on daily basis. When you're off sugar for a while, you notice how those "compulsions" you have during groceries is just due to your gut yearning for some sugar. Now fruits and natural sugar are a lot better, but even them I wouldn't consume excessively if you are in the business of high focus -work.

As a lifelong procrastinator this article reads like "that other Napoleon" aka Eisenhower and his "delegate" for anything neither important nor urgent. I use it when I'm one of several recipients in emails To: address.

Other responders have also talked about Google inbox which I never used but even those of use locked away in enterprise fiefdoms with Outlook can make use of pinned messages (same as starting in Google Inbox) and recently also can be reminded about emails. I use both combined with the approach of trying to clear my inbox as close to zero unread each day as possible. I do same to slack messages as well. For all "messages" I ruthlessly delete or archive anything not needing action and with no legal or revenue impact.

THats how I manage the torrent of comms. Need to improve my work on larger items to start earlier and produce in smaller chunks.

For keeping track of all my work I used Obsidian with tasks and tags and put due dates on all. Helps me see what is due for each "project".

My 2c.

I live in Australia and about half our beef production is apparently grass-finished. I believe what we get in the supermarket is more likely to be grain-finished, but I've definitely bought steaks with the telltale grass-finished yellow fat from Woolworths before. My understanding is that it's more about rainfall and seasonal feed than the particular flavour of one or the other.

For the record, I also think calling grass-fed beef gamey, metallic, and saying it's unlikely to be popular (like the top-level reply did) is an overstatement. The most prominent thing is the different coloured fat. The taste isn't hugely different, probably because our grass-finished beef still gets enough feed.

If this happened to a rector, it shows how normalized it has already become to grab “quotes” off the internet without tracing them back to a primary source. I don’t think this is mainly about AI—it’s the same bad habit that led people to repeat misattributed Einstein lines for years. The difference now is the velocity: LLMs can generate confident-looking citations on demand, so the temptation to skip the source check is higher than ever.

It feels like universities should treat quotes the same way they treat statistics in papers: no citation, no usage. A ten-second verification call or even a quick check in a digital library would have caught this. I’m curious whether schools will start teaching a short “AI hygiene” module for public communications—how to annotate drafts with provenance, how to log which tools were used, etc. The reputational hit from one sloppy speech is probably worse than the hour it takes to verify the material.

body scan is the first pillar of mindfulness

https://suttacentral.net/mn10/en/sujato

anecdotally, I had a late PoTS (postural static tachycardia syndrome, blood vessels don't autonomically constrict correctly depending on posture) diagnosis, then hypermobile EDS (tissue that's more floppy)

I realised on body scan relaxations that

a) a pain arose in most body parts as I tried to gently allow a letting go of tension in that part, like something I had to shake off, kinda like DOMS though also similar to the body tension pain I get as a certain kind of autistic person repeatedly failing a task,

n b) that any however much relaxed part very quickly subconsciously tensed up once again within seconds of my focus moving to a new part. chronic tension from 1) needing to tense for blood to better flow, n 2) trauma. I've had masseurs tell me my muscles fight back, n fwiw prolapse op from the EDS, n I get pregabalin for the tension pain

Nice to see a diff tool aimed squarely at everyday copy-paste comparisons instead of trying to be an IDE plugin. A couple pieces of feedback from a habitual diffchecker user:

• Client-side diffing is great for privacy, but it might help to call out the file-size limits so people don’t assume they can drop a 50MB log in there. Even a small progress indicator when the diff is running would make the “nothing’s happening” moment less confusing.
• Dark mode or at least a higher-contrast theme would be appreciated—most of us are jumping over from code editors that are already dark.

Curious if you’re considering side-by-side character-level highlighting like Kaleidoscope/VSCode’s inline mode. That’s the one feature that usually pushes me back to the heavyweight tools. Either way, thanks for putting another option out there.

I get a little suspicious whenever education is discussed purely in terms of IQ deltas. Most of the leverage seems to come from giving people repeated chances to practice the handful of “intelligent” behaviors that IQ tests reward: working memory exercises, analogies, pattern completion. That’s useful, but it’s not the same thing as raising a person’s underlying capacity to navigate messy real-world problems.

What I’d love to see in these meta-analyses is a breakdown by instruction style. Content crammed through lectures probably does little beyond test familiarity, while project-based or apprenticeship-style programs often force you to build executive function—prioritizing, negotiating, moving from fuzzy requirements to concrete output. My hunch is that the latter matters more for what we informally call intelligence, but we rarely measure it because it’s harder than handing out Raven’s matrices.

> In reality you'll find the vast majority of GPs are highly intelligent and quite good at problem solving.

Is this statement supported by facts? If anything this statement is just your internal sentiment. If you claim it’s not supported by facts the proper thing you should do is offer facts to counter his statement. Don’t claim his statement isn’t supported by facts than make a counter claim without facts yourself.

https://www.statnews.com/2023/07/21/misdiagnoses-cost-the-u-...

Read that fact. 800,000 deaths from misdiagnosis a year is pretty pathetic. And this is just deaths. I can guarantee you the amount of mistakes unreported that don’t result in deaths dwarfs that number.

Boeing the air plane manufacurwe who was responsible for the crashing Boeing 737 mcas units have BETTER outcomes than this. In the year that those planes crashed you have a 135x better survival rate of getting on a 737 max then you are getting an important diagnosis from a doctor and not dying from a misdiagnosis. Yet doctors are universally respected and Boeing as a corporation was universally reviled that year.

I will say this GPs are in general not very competent. They are about as competent and trust worthy as a car mechanic. There are good ones, bad ones, and also ones that bullshit and lie. Don’t expect anything more than that, and this is supported by facts.

Let's assume I publish a github repo with some go code, and tag a particular commit with tag v1.0.0. People start using it and put v1.0.0 into their go.mod file. They use the golang proxy to fetch the code (and that proxy does the "verification", according to your comment). Now I delete the v1.0.0 tag and re-create the tag to point to different (malicious) commit. Will the golang proxy notice? How does it verify that the people that expect the former commit under the v1.0.0 tag will actually get that and not the other (malicious) commit?

I bought 12 eggs from trader joe's yesterday for $2, organics were $5

I get 18 eggs from another grocery store for about $5 and kroger has them really cheap too. Even Whole Foods has 18 for $5-ish in one brand and much more $$ in another.

Publix is the egg-gouger around me (and just overpriced in general)

IMHO the same cheap whole food meals are healthier than a variety of $2 frozen dinners.

You can hit a middle-ground with some frozen stuff to save a little time and money a few days per week too.

> a $50,000 car loan on his house, plus a $50,000 car?

Well I suppose that guy might come out unscathed since many US states protect your primary vehicle in a bankruptcy. But to an approximation declaring bankruptcy involves losing all of your remaining assets. So in that scenario the borrower is on the hook for the cost of replacing those assets (limited by how far underwater they were on the mortgage naturally).

Your other example involved blowing the borrowed money on entertainment in which case I agree that you come out ahead. But that is precisely why I used the term "assets" in GP.

Also I don't think everyone just gets let off scot free after a bankruptcy? Don't you sometimes get stuck with some amount of repayment depending on the nature and volume of your income?

My question about bank failure also still stands. While the impacts of this hypothetical on personal finances are certainly interesting to consider, I'm thinking we really don't want to do the whole widespread mortgage default thing again.

Wow, someone with something to lose finally spoke up / out against the Trump administration! :clap:

While (unfortunately) rather heroic in todays day and age, I fear the retribution he's now called upon himself, Germany, and the EU in particular. Vance and Stephen Miller are already always whispering in Trump's ear about the evils of Europe / the EU, convincing him to take action on whatever they want won't be hard.

Sidebar: the fact that we have to be fearful of retribution due to such rhetoric is really all that needs to be said about the timeline we're currently living through.

Yes.

I've dreamed of using a stylus and tablet since reading _The Mote in God's Eye_ when I was young, and have preferred to use them since using a "Koalapad" attached to a Commodore 64 in the school computer lab when I was young.

The NCR-3125 I had was donated to The Smithsonian by the guy I sold it to, along w/ a lot of other materials on pen computing --- PenPoint was my favourite OS alongside NeXTstep, and the high-watermark of my computing experience was using the NCR running PenPoint as a portable, then cabling it up to my NeXT Cube to transfer data --- had a Wacom ArtZ attached to the Cube, so still had a stylus, just it wasn't a screen.

Futurewave Smartsketch is still my favourite drawing program, and I was very glad that its drawing system made its way through Flash and into Freehand/MX (which I still use by preference and despair of replacing). If you have a graphics tablet, be sure to try out:

https://www.wickeditor.com/#/

Hopefully the folks making Graphite will figure out that it's a core functionality for a drawing program to work w/ a graphics tablet --- haven't been able to do anything when I've tried.

I sketch (either on a Samsung Galaxy Note 10+ or Kindle Scribe or Wacom One or Samsung Galaxy Book 3 Pro 360), take notes (mostly on the Scribe), do block-programming (Wacom One or Book 3), or draw (on the Book 3).

NPM has to decide between either being a friendly place for hobbyists to explore their passions or being the backbone for a significant slice of the IT industry.

Every time someone pulls/messes with/uploads malware to NPM, people complain and blame NPM.

Every time NPM takes steps to prevent pulling/messing with/uploading malware to NPM, people complain and blame NPM.

I don't think splitting NPM will change that. Current NPM is already the "100% use at your own risk" NPM and still people complain when a piece of protestware breaks their build.

You're advocating taking away, a method people have to protect themselves, with a simple "oh, I'm not so sure".

How about you make an iron clad promise people will be safe? How about if someone dies because of your minor concerns, you go to jail for life?

Would you be so "oh well" then?

If not, you're probably not taking people's very lives seriously.

But were the software people actually right, or did they just follow the well-trodden path of VMS / UNIX, instead of making full use of the x86 hardware?

Having separate segments for every object is problematic because of pointer size and limited number of selectors, but even 3 segments for code/data/stack would have eliminated many security bugs, especially at the time when there was no page-level NX bit. For single-threaded programs, the data and stack segment could have shared the same address space but with a different limit (and the "expand-down" bit set), so that 32-bit pointers could reach both using DS, while preventing [SS:EBP+x] from accessing anything outside the stack.

As a European, I used to think, rather uncritically, that the US is fundamentally fairly good (not perfect but ultimately a good egg), yes some dirty business on the "fringes" of the world or a long time ago (like say, Iraq or Cuba) but "we", the "Western world", are OK and buddies, and US's good behaviour towards us reflects their true nature.

My new impression is that there's a nasty streak in the US that simply went against other people for a long time - Native Americans, African slaves, South America, Iran and the Middle East - and it was inevitably going to come out against Europe too at some point. At the end of the day, Trump can do what he does because the Congress accepts it, it accepts it because they are ideologically aligned, and a majority of American voters selected them.

I'm not picking on the US here. Plenty of countries, maybe all, have a nasty streak or ten, it's human nature. But I though the US is actually somehow better, with its institutions, its painful lessons from the country's birth, yada yada. Actually maybe they're as bad as the rest of us, but just much more powerful.

>> they chose or were forced to leave.

Again, that is not speaking well of the acting government. Is just not normal that so much people choose or even worst are forced to leave. That just does not speak well of that regime. Does it? So dismissing their opinions does not seem to be a useful reasoning. I know from friends of mine in many different places in Latin America (mind you, in both "left" (brasil/MX) and "right" (Arg/ Chile) countries) that there are literally thousands of venezuelans in exile. That is not normal and is not a good sign.

> bottom line Trump doesn't care about good governance and democratic in Venezuela

Totally agree. But as I said, is not "Trump". Is not a person, is institutional. Which you could reasonably argue is much worse. But OTOH, there are many people again, does not matter if they went or stay... many people from that very country that are very happy with the intervention...

My way of seeing it is: we have to wait to be able to weight the prons and cons. WWII + Plan marshal was basically the same, wasn't it? And I'm pretty happy with the results and how everything played out...

I doubt that anyone is actually suggesting that Siri should not be better, but to me I think the issues with it are very much overblown when it does what I actually ask it to do the vast majority of the time since the reality is most of the time what I actually want to ask it to do are basic things.

I have a several homepods, and it does what I ask it to do. This includes being the hub of all of my home automation.

Yes there are areas it can improve but I think the important question is how much use would those things actually get vs making a cool announcement, a fun party trick, and then never used again.

We have also seen the failures that have been done by trying to treat LLM as a magic box that can just do things for you so while these things are "Technically" possible they are far from being reliable.

> We are ending the war on protein. Every meal must prioritize high-quality, nutrient-dense protein from both animal and plant sources, paired with healthy fats from whole foods such as eggs, seafood, meats, full-fat dairy, nuts, seeds, olives, and avocados.

This is some seriously radical stuff, if you take it literally. Every single meal you eat "must" prioritize protein? Why? Who is lacking protein in America?

> how in explanations of attention the Q, K, V matrices always seem to be pulled out of a hat after being motivated in a hand-wavy metaphorical way.

Justin Johnson's lecture on Attention [1] mechanisms really helped me understand the concept of attention in transformers. In the lecture he goes through the history and and iterations of attention mechanisms, from CNNs and RNNs to Transformers, while keeping the notation coherent and you get to see how and when in the literature the QKV matrices appear. It's an hour long but it's IMO a must watch for anyone interested in the topic.

And as an aside, conversion measurement is der rigueur in digital advertising— for obvious reasons, companies don’t publish it. It is the basis for A/B testing which uses large sample sizes to see which presentation is more likely to make people do or not do something. It’s easier than ever to tell where someone was exposed to something and the click trail they took to end up on a purchase screen. I don’t, nor have I ever worked in digital marketing, but this information is extremely easy to find. Additionally, the Freakonomics guys are no strangers to vibing their way through topics they know nothing about and mistakenly assuming their brief thought experiments and unchallenged researchers have uncovered something useful. It’s not like they’re never right, but they’re no stranger to unforced errors in their analysis and you’d be wise to not rely on them as a source.

The question one needs to ask reading these kind of news is: who is monitoring speeches made by rectors of minor universities to check if there is anything embarrassing in them? And why this piece of embarrassing but obscure trivia is spread as news?

And the answer is simple: De Sutter is a vocal critic of Israel and has called for it to be sanctioned. So there is someone digging up dirt to damage her. Such are the methods and powers of zionists.

Early Buddhist Texts (EBT) are fairly non-religious, e.g. see the Thai forest tradition/BSWA talks

this school of thought even often ignores a fair portion of the abhidama texts ("about dhamma", the meta commentaries) that started to form a number of years after the death of the Buddha

The wild part about all these notification-firewall concepts is that we keep re‑creating the same tool in closed source. Why not ship it as open source, charge for the hosted rulesets or ML models, and let people audit the code they’re literally piping every OTP and DM through? “Trust us, we don’t phone home” isn’t a strategy anymore when GrapheneOS, NetGuard, and even Pixel’s Data Saver already cover 80% of the use cases. The only reason I can see for keeping it closed is that the real business model is eventually selling the telemetry back to the very advertisers it claims to block. Am I missing an actually compelling reason not to open it up?

> Police will not arrest if the DA won't prosecute.

Why not? If the police are frustrated that the DAs aren’t doing their job, I don’t think it helps the police any to choose to also not do their job. Especially since DAs are often elected, which means it’s easier to replace them if the police can show that they (the DA) are the bottleneck. But if the police don’t do their job first, then the police are the bottleneck.
