Show HN: Dealerlytix: AI Inventory Intelligence for Car Dealerships
by nubani | 2025-07-23 23:36:58+00:00
We’re launching Dealerlytix, a SaaS platform that helps car dealerships make smarter buy/sell decisions with AI.

Problem: Dealers often guess which cars to buy, how to price them, and how long they’ll sit on the lot. Most rely on gut instinct or basic tools that don’t leverage their own historical data.

Solution: Dealerlytix connects to your inventory data and gives you: • AI vehicle scoring: Predict sale speed, profit margin, and optimal price before you acquire a unit. • Smart inventory assistant: Ask questions like “Which SUVs under $30k sell fastest at my store?” • Lifecycle tracking: Repricing history, profit snapshots, color trends, and seasonal performance.

We focus on your dealership’s actual performance history, not generic market trends.

Who it’s for: Independent dealers, auto groups, and high-volume used car operations that want to turn their data into smarter decisions—and more profit.

Looking for: • Feedback from SaaS founders and devs • Dealership insiders to pilot the platform • Smart closers to help us scale sales (remote + commission)

Live now at: https://dealerlytix.com

Would love your thoughts.

Here’s how this is working in practice:

There’s a fast-growing cottage industry of companies using AI to figure out how to bill insurers “better”

And there’s a fast-growing cottage industry of companies using AI to figure out how to deny claims “better”

I see no reason to expect improvements to the patient or provider experience from this. A lot more money spent though!

The first beta often ships with core features missing or broken. It exists to get as many new features in front of third party developers as soon as possible, because Apple has very little time to accept feedback before they are locked in for shipping.

At the same time, there seems to be precious little time between when Apple decides a feature is going to ship in the next release, and when WWDC happens.

Even if there was common knowledge inside the company that a new UI was coming, it may have not been merged into mainline until closer to WWDC. At that point, individual teams will need to alter their code to build and be usable on top of the UI as part of continuing their own development - but were likely still focused on the death march for their own WWDC-launched features.

So Python 3.14 introduces this functionality. The process you want to debug needs to be on at least Python 3.14.

If you want to "just" use sys.remote_exec, you will need to use that from a matching Python version. If you dive into the implementation (check out the PEP), you could most definitely write a C or Rust program that implements remote_exec and "does the thing".

The protocol is basically "tell the program to read a python script from this file". That python script will be executed in the running program's environment, but you don't need for the software on the other side to be a python program!

sys.remote_exec itself only targets same Python versions though.

- We've used pg_repack in the past, though I'm 90% sure we didn't use it in the timeframe in which this corruption must have happened. Anyway, we'll look into this further: thanks for the suggestion.

- Yes, we've done OS upgrades. Back in 2021, our DB servers were on Debian Buster; they are now on Bookworm. We're aware of the problems caused by collation changes, and indeed that was one of the first things we checked; but we're careful to use the C locale for our database, so believe we're safe on that front.

- For the example we gave (index page 192904826, referencing heap page 264925234), the index page LSN is DB4A3/C73ED0C0, and the heap page LSN is DB4FA/4CAAB9D8, so the index page was written shortly before the heap page. The blog post shows the output of SELECT * FROM heap_page_items for the heap page: it looks like a regular empty page to me.

In my view we most certainly do, though of course not all the time.

Oscillations typically happen when moving quickly and then stopping at a certain position.

A prime example is the ISSF 25m rapid fire pistol event, where you start with the pistol pointing down at 45 degrees, and within 8, 6 and 4 seconds have to raise the pistol and take 5 aimed shots.

Beginners will often find they oscillate vertically above and below the center of the target as they raise the pistol, and it usually takes a fair bit of practice not to oscillate. This is more pronounced at the rapid pistol events due to the tight time constraint forcing them to move quickly, especially at the final 4 second round.

Another example is gymnastic rings, especially when they go from a swinging motion to stopping vertically or horizontally.

Anticipation-like movement often occurs when we want to get a bit of extra momentum. For example, casually tossing a base ball or tennis ball often results in a bit of backwards movement first, before the main swing. Typically it's one smooth movement.

The UR10 uses 100:1 strain wave gearing in the base and shoulder joints.

You’re right that it has a freedrive mode, and force control modes. But it’s a rigid, low-backlash robot with the compliance achieved in software afterwards.

Expensive, naturally, but none of the problems that come with things like series elastic actuators.

I've seen this pattern quite a bit with our users, and we've implemented "snapshots" for this.

It essentially makes a copy of your entire state of the runner, which you can then use in subsequent runs, with no concurrency limits.

This essentially automates out a lot of the work you're doing to make the jobs faster.

https://docs.warpbuild.com/snapshot-runners

We provide a product similar to Blacksmith.

- Odysee - Has an easily accessible RSS feed, a link to download every video and it has no ads. Unfortunately nothing original going on here. Just a repository for YouTube's sloppy seconds.

- BitChute - If you can get past the 'racists' and the MGTOW gayness that dominates the front page, this site has a rather large catalog of free movies available.

- Rumble - If you can get past the political slop, this site streams a lot of NFL sportsball for free .

- Twitch - I used to go here to watch my sportsball but the site is now overexposed, old and busted. Can't go five seconds with a copyright notice appearing.

I have been served plenty of pork chops and ribeyes that have been pre-sliced. It is a pretty common presentation when the cut has the bone on. The meat will be cut off the bone, sliced, and then placed back nestled next to the bone. Slicing and fanning gives you more surface area for some finishing salt. This is even more widespread when it is a large steak intended to be shared among two guests.

Currently my biggest productivity killer is being pulled into meetings with a customer. I'm working on project that needs extremely deep and focused work but my week is littered with external meetings with customers and that context switch is much harder than an internal meeting I have to not only drop all the context of what I was working on but also "reset" my brain to go into customer mode. Why? Because my company is a nuclear garbage fire among other things...

Just one of these meetings can nuke my productivity for an entire day depending on the meeting context and just one per-week is a combo-breaker for multi-day deep work productivity.

Pretty sure they all had the touchscreen ('13 981BS here.) The screen is usually used for nav, Sport Chrono, and other bells and whistles, but even with the standard audio system it should let you use the screen to adjust the tone controls, radio stations, and stuff like that. The CAR button should also bring up a menu with various settings.

The idea behind the stalk is more to let you control the instrument-panel display if you don't have the multifunction wheel controls.

I have a Mr12Volt CarPlay adapter in mine that works nicely, although capacitive multitouch would be a lot better for that. Key point of course is that none of this gadgetry is actually required when driving. They will take this car when they pry my skeletal fingers off the buttons.

>Top Gun: Maverick and Taylor Sheridan’s nostalgic, libertarian-inflected Yellowstone. And a longstanding Christian culture industry has backed projects like the 2023 film Sound of Freedom, a dramatization of child trafficking that grossed more than $242 million for Provo’s Angel Studios. The Christian drama The Forge earned $30 million on a $6 million budget last year.

There’s good evidence that this is an untapped market which normal studios are too afraid to tap.

I don’t think it’s ridiculous at all. If you listen to people on the right they have felt unrepresented in popular entertainment for a long time, and these successes are evidence that they are willing to pay for entertainment which aligns with their values.

Try going through your watch history and deleting stuff that isn't relevant to your current interests. My experience is that the recommendations are keyed very heavily (entirely?) off your watch history so, unlike most apps, you actually have quite precise control over what it recommends.

I'm really diligent about whenever I watch something that I don't want YouTube throwing more of at me, to just immediately delete it from my history. For example, if someone on Reddit mentions some funny dumb video, I'll watch it, but then delete it because I really don't want YouTube suggesting schlock to me.

> Jurisdictional safeguards have always been snake oil.

The lore persists from thepiratebay's stand against copyright enforcers (basing themselves from countries like Sweden)?

> the IC is literally chartered to grab things from servers in countries like Switzerland

tbf, even if Switzerland might not be it, just like tax havens, there has to be colo havens? Before the AI hype, VCs (I mean, engs) did try to ram down web3 / decentralised tech (like helium, golem, storj/filecoin), but I guess those didn't catch on with these mainstream VPN/privacy types.

i’m getting super fatigued on this change we’ve had where what used to be beta testing to a closed group of invested parties has morphed into what we have now.

from video games to major product roll outs to cars.

will all of the knowledge gained from this product research testing of AI on medicine be given away to the public in the same way university research used to be to the scientific community? or will this beta test on the public’s health be kept as company’s “trade secret”

if they’re going to “move fast and break things” with the public, in other words beta research on the public, then it’s incredibly worrisome if the research is hidden and “gifted” to a handful of their cronies.

particularly so when quite a lot of these people in the AI sphere have vocally many times declared they despise the government and that the government helping people is awful. from one side of their mouth chastise government spending money to boost regular communities of people while simultaneously using it to help themselves.

I've asked ChatGPT to summarize (granted my prompt might not be ideal), but some points to note, here just first in details others in the link at the bottom:

Calling C from Go (or vice versa) often requires switching from Go's lightweight goroutine model to a full OS thread model because: - Go's scheduler manages goroutines on M:N threads, but C doesn't cooperate with Go's scheduler. - If C code blocks (e.g., on I/O or mutex), Go must assume the worst and parks the thread, spawning another to keep Go alive. * Cost: This means entering/exiting cgo is significantly more expensive than a normal Go call. There’s a syscall-like overhead.

... This was only the first issue, but then it follows with "Go runtime can't see inside C to know is it allocating, blocking, spinning, etc.", then "Stack switching", "Thread Affinity and TLS", "Debug/Profiling support overhead", "Memory Ownership and GC barriers"

> Programming takes the cake for what is both my most and least favourite part of any build. Nothing quite makes you pull out your hair and ask yourself, 'What the heck have I gotten into?' Like spending weeks programming a robot that just won't work. Eventually though, you fix that one line of code that makes all the difference. And then it's smooth sailing. Well, kind of.

I feel this deeply, also this whole video is quality content.

Administrative risk, mostly. If you accidentally wipefs the wrong disk when moving it to the RAIDZ2 pool or offline a real disk instead of a tmp disk or make some other simple mistake then a zpool might be unrecoverable.

An alternative would have been to build a RAIDZ2 out of three new disks and two tmp files and then copy the data over and finally offline a RAIDZ1 disk and online it on the RAIDZ2 zpool. Two copies of the data in each pool would require an actual disk failure in both zpools to lose data during the resilvering (even though both were degraded), and when breaking the original zpool to add a replacement disk for the 5th device in the RAIDZ2 pool you'd have to lose two existing disks in that pool to lose data.

No criticism; it's cool to be able to do moves with minimal resources and I've also thought about potential ways to upgrade zpools under weird constraints; especially no free SATA ports for example. I had thought about using the four SATA ports to copy data from half the source disks in a RAIDZ2 to half the destination disks of a new RAIDZ2 while the removed disks would still be a functional zpool on their own as a backup. But ultimately I found a cheap extra box and went for a complete upgrade to larger disks with the benefit of keeping the old box as a local mirror.

My upgrade was from a single RAIDZ2 of 4x 4TB disks (8 usable) to a RAIDZ1 of 4x 14TB disks (42 usable) because once both pools existed I was comfortable running the old disks in a 12TB RAIDZ1 to receive snapshots from the primary zpool while I had <12TB used. Still requires 2 disks to fail to lose data, and now I do some offsite backups as well (rsync and s3backer) and have a test system to perform upgrades on before the main system.

The metric of run/not-run is too simplistic. You have to divide out the total throughout the system gives to all concurrent users (which we don't know). Like a golf-cart can get you from New York to LA same as a train, but the unit economics of the train are a lot more favorable, despite its increased cost. The minimum deployment scale is not irrelevant, it may make it infeasible to run an on-prem solution for most customers for eg, but if you are selling tokens via a big cloud API it doesn't really matter.

Not necessarily, various objects can look completely different in different wavelengths and it's not really possible to interpolate without taking a picture of each part of the spectrum.

The Milky Way and the entire local group of galaxies are flowing towards the superclusters located directly on the opposite side of the galaxy, and there's huge (thousands of light years) clouds of gas and "dust" (supernova molecular feces) that are like actual, thick, opaque storm clouds that form a donut around the galaxy, so it's impossible to "see" where we're headed except for the the X-rays and mid-infrared that doesn't interact with the huge clouds. And we won't be able to until we can leave the plane of the Milky Way's disk, or we build a telescope that is 2 dozen orders of magnitude more sensitive than anything we have so far.

Managing energy levels is my main bug here. Wish I had done this pre having kids but now with full time work and that I dont feel like socialising every day to this extent and moreover if I push through and do that I get more tired at work and underperform.

But I'm not a doomster so my plan is:

* Leverage stuff I have to do anyway at work for performance reviews. Initiatives means talking to new people at work.

* Attend school related social events.

* Family connections. No I'm not well connected like that, just chat to family.

> European companies are just run the same way EU governments are run, on austerity and cost cutting

To a certain extent yes.

But that's because of margins. An large automotive parts vendor or a major biopharma company isn't generating revenue on software, so software engineering is treated as a cost center.

It's the same in the US, but at least you have tech first companies that generate most of their revenue of tech.

Europe's tech industry died out because of a mixture of mismanagement and bad luck. Velti [0] used to outcompete AdSense, but their management was incompetent and borderline fraudulent, and that's why the AdTech industry boomed in the US and collapsed in Europe.

The same thing happened to Nokia, Ericcson, and others.

The good European startups like Datadog, Spotify, Databricks, and UIPath all ended up relocating to the US so an entire generation of startups doesn't exist in the EU.

> they instead try to increase the profits by cutting all possible costs from purchasing to labors' wages and offshoring, since I assume that's also what's taught in European MBA schools

I've dealt with MBA grads from the EU and US - they aren't taught any of this. IMO, the issue is most leadership in European companies tend to be ex-accountants from KPMG/EY/PWC/Deloitte/Mazars-type companies, because manufacturing industries like pharma, automotive, etc have severely low margins.

Americans (at least) approach many dynamics with the same zeal (and irrationality) as they do racial issues. Think about the "green iMessage bubble" controversy. Think about sports fandom. It's not that those situations are comparable in their seriousness, but people do use dumb things as alarmingly inappropriate heuristics for how to treat others. They project unrelated behaviors onto things that apparently rise to the level of minor identity signifiers, and then people get genuinely hurt - or, speaking more directly to HNer interests, products fail because markets go underserved as second-class customers (waves at Meerkat).

What’s ironic to me is that had these companies pirated only a single work, wouldn’t that be a chargeable crime?

Clearly Bonnie and Clyde shouldn’t have been prosecuted. Imagine they were just robbing banks for literary research purposes. They could have then used the learnings to write a book and sell it commercially…

Or imagine one cracks 10000 copyrighted DVDs and then sells 30 second clips… (a derived work).

To me, for profit companies and universities have a huge difference — the latter is not seeking to directly commercially profit from copyrighted data.

The builder splits their work into milestones and the funds get released at the beginning of each milestone. Users are just group-buying someone to do some work. The builder is getting a reputation in the process. Think ebay.

When work received, the funders rank work according to overall quality, and quality against the expectations set. It's like ranking a purchase on ebay.. overall was this purchase good? How many stars? etc.

Who resolves the disputes? No one. The funds go into escrow for 2 weeks, if over 70% of funders reject the work, the funds are returned. Not sure if some funds can be retained, however. I suppose the "rejection retainer" can be customized. Also, the builder's code can go into escrow too so the builder keeps their code. The problem is crap code, what if the product is good but the code ends up bad? I suppose too bad.. the builder just suffers reputation wise.

Also, the builder's dev environment can be streamed as well, and an ongoing conversation can occur. There's a sharing and collaborative process. That will keep users aligned. Like with gaming or music creation. Potential funders can watch someone work and think.. is this someone I want to work with? So it's about making it personal, but with rules in place and removing the need for arbitration. That doesn't have to be a must, but can work for some situations.

The bare-bones product can be fairly black and white and gradually build features as problems/opportunities arise.

Perhaps builders can choose or at least know about their funders' rejection rates in advance and actually select their funders if a project is over-demanded (under-priced?) Sort of like Hipcamp hosts' response rate and wait-time - would you message someone who never responds? The key is reputation on both sides - like ebay. Hipcamp hosts also can reject bookings for their listings if it's not an Instant Book so bookings are discretionary.

Also, maybe funder and builder wallet totals can be revealed. Would it help to know if one of your funders or builders is a billionaire? What do you think? I suppose it could be optional. It'd be more for status, because you can easily fake a low wallet balance, but can't fake a high one, or not easily.

"Oh, I know absolutely nothing about this funder, except that he/she is friggin' loaded... oh wait, maybe I can charge more.. or less! This coin is going to be pumped 'til kingdom come!" So there's a name for it - "KingdomCome" or just Kingdom...KingDome?!

I have no problem with unions as a concept and if people want to join them that's fine with me.

However, unions in practice enforce mediocrity while also becoming an institution that exists to support itself (aka its leaders) rather than its members once it reaches a large enough size (which is not unique to unions at all).

Unions makes no sense for a top performer in a field where an individual can outperform other workers performing similar tasks by orders of magnitude. Software development is one of those fields.

What part of that do you take issue with?

> Inside the meat, heat was flowing from the hotter exterior towards the center, cooking it further, a phenomenon colloquially called "carryover cooking.

Yes, this is the exact reason I always rest mine.

When you cook a steak on a cast iron, if you wait to pull it until the internal temp is reached, you'll end up either burning it or drying it out depending on temp.

The best way is to cook it as absolutely hot as possible to get a good sear, then just let it sit. As long as it's fatty enough(or you use enough oil, depending), the center will continue to heat long after you remove it.

I previously used Synology since 2016 but I'll never buy them again, due to a combination of how poor their hardware options are and how unfriendly their recent policy changes have been.

My next NAS will probably be an NVMe-only computer, lots of options emerging these days with 4 - 6 slots as China has become infatuated with designing small NAS.
