Show HN: I've Made a Tool to Track TikTok and Reels Accounts' Performance
Hey HN,

I've been doing most of my marketing for my consumer apps with short-form content. At one point, I was operating 10 accounts, posting daily, as well as doing influencer marketing, posting dozens of videos a week.

It became really hard to track everything, so I built this tool that pings videos once a day and retrieves the data.

You can view everything from a single dashboard. I even use it to track competitors.

It's been mega helpful for growth.

Hope it can help you too.
How Scientists Captured the First Image of a Black Hole (2019)
In my experience the drag caused from the thinking to plan for scalability early has been so much greater than the effort to rearchitect things when and if the company becomes a unicorn that one is significantly more likely to become a unicorn if they simply focus on execution and very fast iteration and save the scalability until it’s actually needed (and they can hire a team of whomever to effect this change with their newly minted unicorn cachet).
Ask HN: Do you consider a Personal CRM to be a tarpit idea?
Hi! I participated in the r/yc discussion on tarpit ideas.

Could a personal CRM be considered a tarpit idea?
From the first look, the problem of relationship building sounds common and relatable, that's an attractive component. But a very small share of people are actually willing to regularly keep notes about their connections. That makes the real audience much smaller.

I am curious to know your opinion of personal CRM viability. Is it tricky to make a good product and business from?
What is wrong with investors to give Elon Musk more money for his me-too products? Why would they waste $6,000,000,000?
There has been some recent stuff going on with GME, but what the article is referencing is events that happened in 2021.

Quoting:

On-Topic: Anything that good hackers would find interesting. That includes more than hacking and startups. If you had to reduce it to a sentence, the answer might be: anything that gratifies one's intellectual curiosity.

Off-Topic: Most stories about politics, or crime, or sports, or celebrities, unless they're evidence of some interesting new phenomenon. Videos of pratfalls or disasters, or cute animal pictures. If they'd cover it on TV news, it's probably off-topic.

Qajobs.co: The premier quality assurance job board
I did some work with Rete for my undergraduate dissertation. One thing I remember about the original paper is that it defines the algorithm in terms of a kind of virtual machine, where specific instructions implement the matching process. I’ve never seen anyone implement it that way.
Any additional information compared to the official announcement? https://news.ycombinator.com/item?id=40466810
The first thing I thought of was how high performance aircraft have unstable aerodynamic flight profiles: because if you want to turn, then you want the tiniest control input to give you the hardest possible manoeuvre (then let the control software prevent crashing).
On the contrary, they are likely very familiar with <thing> and their judgement comes from experience.

> Also if the new module is not exactly the same as the previous ones you can very easily run into stability issues.

Even with the same module, syncing up 4 modules to rated speed is going to be a challenge to boot, let alone have it be stable. If you want density, a platform that supports RDIMMs is the way to go with DDR5.
The artist impression in the article is heavily misleading IMHO. The actual "ring" is much more jagged and looks very similar to all the nearby so called "filaments" they labeled. I'm not sure if it's crossing the threshold from constellation-ism to real astronomy. Download the arXiv paper and see for yourself.
Ask HN: Local Alternatives for DeepL Write?
A while back I discovered DeepL Write and I love it. However, I got lazy with writing emails and a couple of days later an AI researcher of the company viewed my profile on LinkedIn. Pretty creepy, but to be expected with the ToC.

Anyone know an alternative that I can run locally without having to wrap it in a prompt every time?
Reproducible Builds (A Hypothesis Against Of)
That's a great idea to record locally. Do you keep a deep history or wipe after 30/90/365 days? Do you need any special hardware for it?

My memory is not great. I'm starting to have more calls with clients and it would be great to have a record rather than trying to take notes and conduct a conversation at the same time.

> It should be automatized so that if you miss part or all of a meeting you can still watch the record as long as you were invited

People generally don't like knowing that everything they say is being recorded
I think you nail it. It is all about that honesty vs the hype.
As doikor said, it’ll halve your RAM speed. That’s not a rule, but it’s typical.
Thank you for pointing this out!

Actually the flow of this project was implementing everything on my own, and at a later stage realizing that JTS already does a lot, and then refactoring and dropping most of my features :D

I was just fiddling around in Kotlin, JTS seems like a banger library though.
The biggest problem with planning for scale is that engineers often have no idea what problems they will actually run into when they scale and they build useless shit that slows them down and doesn't help later at all.

I've come to the conclusion that the only strategy that works reliably is to build something that solves problems you have NOW rather than trying to predict the future.
Sorry, archive site not working for me so I can't add an archive link. I thought this would be accessible as "one free article" most news sites give.

The calibration to get just 2 sticks to be stable is around 20-50 seconds already, during which the memory controller is testing different sequencing and even clocks for individual lanes to minimize interference. So unless you want to stop the entire CPU if you need that memory, no.

You're running a signal at 2.4+ GHz (commonly 3 GHz for DDR5-6000) over 288 pins over several centimeters simultaneously, it's not pretty.
When I was hiring data scientists for a previous job, my favorite tricky question was "what stack/architecture would you build" with the somewhat detailed requirements of "6 TiB of data" in sight. I was careful not to require overly complicated sums, I simply said it's MAX 6TiB

I patiently listened to all the big query hadoop habla-blabla, even asked questions about the financials (hardware/software/license BOM) and many of them came up with astonishing tens of thousands of dollars yearly.

The winner of course was the guy who understood that 6TiB is what 6 of us in the room could store on our smart phones, or a $199 enterprise HDD (or three of them for redundancy), and it could be loaded (multiple times) to memory as CSV and simply run awk scripts on it.

I am prone to the same fallacy: when I learn how to use a hammer, everything looks like a nail. Yet, not understanding the scale of "real" big data was a no-go in my eyes when hiring.

Good Start Point to Learn Qt?
I'm in the process of learning c++, my goal is to make desktop apps and I want to start with Qt6, any recommendations for learning resources? (Resources different from documentation)
It's a little hard to learn those, because compared with web technologies, it doesn't have much content
HTML1.1, HTML2, etc weren't less strict, if anything they were more. They only consumed tags that could be rendered, since there wasn't a concept of a DOM tree or anything like that. They just worked forward rendering as they went. CSS and JavaScript introduced the need for a DOM tree and mutable state, in which case HTML renderers treated HTML docs more like XML descriptor files than SGML.
There is nothing really surprising about this.

Jim Simmons that recently passed away did exactly this in finance decades ago. He didn't build a team of the brightest minds in finance.

He hired brilliant people that specifically did not work in finance. I think he even mentioned that astronomy was one of his favorite areas to hire from for finance.

I am sure we highly underestimate the indoctrination against new ideas that anyone at the top of a field has been subject to.

Humans love to turn everything into a high school prom king/queen popularity election though even when it is obvious the best people for the job didn't even go to the prom.
It's not enough tiers, though, because (at least in my experience and the sense I get from other people) the specialists still have only mastered the 20% of issues that account for 80% of cases.

I'd love to see two more Pareto levels, at least. Like, an "advanced practice specialist" could cover the next 4% of things to pick up 16% more of the cases. And maybe one last tier that covers 0.8% of things that account for 3.2% of cases.

Granted, this still leaves 75.2% of the entire list of bizarre possible things that could go wrong hard to diagnose and treat, and that will be hard for the 0.8% of patients where something insanely weird is happening, but with a bit of humility about what it's even possible for our scientific knowledge to cover about "all the possible things that could ever go wrong," and in recognition that we'll essentially always just be doing the best we can to help people and we may not be able to help everyone, those seem like decent target numbers to me.
You've missed the point of that explanation. It could have been 10M spread over 10 excel files with that much. The whole reason they made that edit as people were telling them to do the 20 copy and pastes by hand.
They may work as expected (and probably will), but they are not covered by the proof.
haven't made a pcb in a long time but when i did, used Altium & there were design rule checks for everything; but, none for creepage. Interesting, thanks for sharing.
I'm all for tools like this if they allow me to review my activity, especially if that's across the multiple systems I use, to get a handle on how and where I spend my time.

It's not a surprise that Microsoft and Apple are determined to get us to use their cloud products for our personal data - there's billions up for grab.
Hi, I found the Krita SD plugin docs here: https://www.interstice.cloud/plugin

It seems it needs Docker to be installed? It might consume more power than running in a local Python environment.

By the way, the plugin is great.
This still doesn’t address the claim that ‘first’ is wrong, and that sort of hyperbole, if wrong, is quite off-putting. If this is really ‘quite promising compared to existing…solutions’, there’s no need for inflated claims.
There was a Show HN earlier this year that does one better: it does voice recognition. translation, and then deepfakes the original voice and redubs it: https://news.ycombinator.com/item?id=39512912
What do you mean by 'variety'?
Pretty sure it's your figurative arse but potato, pot-ahh-toh
No, it was not. It was common to spank your children, out of care and love, when they did things dangerous to themselves or others, and sometimes a strap or switch when something truly horrific was done.

We now view this as wrong, but that wasn't beating them.

Yes, some idiots did beat their children, or hit their children out of anger. That doesn't mean it was common.
No, the signal integrity loss is caused by the physical presence of the additional modules.
Why did you clone Linear’s website?
Seems totally legitimate to me. The plugin creater has a superb distributed editor with lots of capability that they choose to add to.

I note that obsidian itself is free. I pay for the built-in sync as that's cheaper than implementing it myself, and there are other paths to sending the developers money, but they're all optional.
In a production environment, where you deal with huge sets (think OSM), the solution may be a mix of both.

One aspect that I didn't deal with (yet) is also, that a Polygon can have redundant points (think A(1|1) B(2|2) C(3|3) D(1|2)), which you should simplify.

Ideally you would also split the map into hexagons, and compute which Geometry lays within which hexagon(s), and then only compare the geometry that shares a hexagon(s), but this information should be persisted and not computed each runtime, making it a bit out-of-scope for pure GeoJSON hashing.
No, I want a way to remove any LLM. Though this is as likely add your regulation hope
Is there a spec for S-expressions as a data transfer format? I’d love to try it as an alternative to JSON.
Perhaps that is inexcusable. GNU gcc version 13.2.0 (with -O2, as documented) does report a problem.

int main () {
int x[10];
return *(x+20);
}
$ gcc -Wall -O2 tst.c
tst.c: In function ‘main’:
tst.c:3:10: warning: array subscript 20 is outside array bounds of ‘int[10]’ [-Warray-bounds=]
3 | return *(x+20);

I have the opposite experience with Siri. Maybe it’s my Australian accent. I have HomePods around, and I use them for lots of stuff. But the voice assistant is barely useful.

“Hey siri, turn on the amp.” “Ok, your media will play louder.” “Siri Set alarm for 4:18” “I’ve set an alarm for 8 o’clock” “hey siri cancel alarm” - radio silence. (Listening to podcast, and my alarm goes off) “hey siri stop” (the alarm stops, so does the podcast). “Hey siri play” “ok, here is some media” (random music plays) … uuurrrrrgghhhh.

I can’t wait for chatgpt to replace Siri.
> I just instinctually don't even bother with new (as in 3-4 years old) CSS or JS features most of the time. It's pretty deeply ingrained in me and I suspect many other devs who were around in that time.

I'm also a web dev with nearly 20 years and do exactly this as well. Old versions (or any version of) IE crushed our dreams too many times to feel comfortable delivering anything modern, let alone cutting edge.

Sure it is. You just need a one to one function from person to [0, eight billion]. Use that as your array index and you're golden. 8 GB is overkill, really, you could pack some boolean datum like "is over 18" into bits within the bytes and store your database in a single gigabyte.

Writing your mapping function would be tricky! But definitely theoretically possible.
Dissecting innovation thresholds with Vinton Cerf
Well define "safe". If we compare the US to the UK for example, it's considerably safer driving in the UK. Surely investment in some level of change that is causal on that level will result in more lives being saved than introducing a whole new technology arena with unknown risks?

Having driven in both places, the driving standards in the US are much much worse. Perhaps we should concentrate on that first? And because not everyone will be able to afford a self-driving car utopia, perhaps it will have a greater effect.

As always the technology industry perhaps is using this justification to solve the wrong end of the problem.
Lol, looks like Huawei really has a choice?
I think the bigger problem is that most people already have a basic level of this type of functionality built in to whatever devices they're using, in the form of the contacts/address book. And obviously that's not nearly as powerful as a proper CRM - but it provides a way to store details about the individuals, notes, when you last communicated, etc.

So you're not just looking for people who want to keep regular notes/etc, but also ones who need something more powerful than the built in functionality already available to them. And they need to trust you with all that (potentially very sensitive) personal data, and hope that you'll be around for the long term (because it would be very annoying to lose that).

Could be an interesting project (especially integration with all the different platforms they may use); but hard to see how it would make much money.

TCC doesn't do any optimization at all, so it shouldn't be that perplexing.

But any compiler that does constant propagation, inlining and (ideally) integer range analysis can optimize away most run-time bounds-checks already. If GCC or clang did it, it would probably be fast enough.

Assuming you're serious for a moment, I don't think AI is really a practical tool for working with big data.

- The "hallucination" factor means every result an AI tells you about big data is suspect. I'm sure some of you who really understand AI more than the average person can "um akshually" me on this and tell me how it's possible to configure ChatGPT to absolutely be honest 100% of the time but given the current state of what I've seen from general-purpose AI tools, I just can't trust it. In many ways this is worse than MongoDB just dropping data since at least Mongo won't make up conclusions about data that's not there.

- At the end of the day - and I think we're going to be seeing this happen a lot in the future with other workflows as well - you're using this heavy, low-performance general-purpose tool to solve a problem which can be solved much more performatively by using tools which have been designed from the beginning to handle data management and analysis. The reason traditional SQL RDBMSes have endured and aren't going anywhere soon is partially because they've proven to be a very good compromise between general functionality and performance for the task of managing various types of data. AI is nowhere near as good of a balance for this task in almost all cases.

All that being said, the same way Electron has proven to be a popular tool for writing widely-used desktop and mobile applications, performance and UI concerns be damned all the way to hell, I'm sure we'll be seeing AI-powered "big data" analysis tools very soon if they're not out there already, and they will suck but people will use them anyway to everyone's detriment.
I read parent's comments more as a counter argument to the suggestion more people would be vegetarian if they had to kill their own animals for food, not a moral justification based on "people used to do it".

> “The existing two-day period to settle trades exposes investors and the industry to unnecessary risk and is ripe for change,” Robinhood CEO Vlad Tenev said in a February 2021 release. “There is no reason why the greatest financial system the world has ever seen cannot settle trades in real time.”

There’s important context missing at the end of the article. It came up at the time, but it’s a little ironic (given how much of their business relies on customers trading on margin) that Robinhood was advocating for real-time settlement, since that would dramatically limit the ability of entities to trade on margin. Delayed settlement of T+1 (or even T+1/2) allows brokers to net out trades at the end of the settlement period, rather than needing everything to be pre-funded. It’s not a technical problem that we’re not going to T+0, it’s a policy decision.
I would argue that with mandated TLS, there is no such thing as "full self-hosting" any longer if you want to be part of the web. Everyone is beholden to a CA somehow
It felt like the driver should have hit the brakes a lot earlier, though.
An "ad-hominem" attack would be an attack on Mr. Howard "as a person" in order to invalidate his argument. For example: "Terrence Howard is a bad movie actor therefore his scientific ideas are wrong." (I think he's a good actor actually!)

He certainly is an interesting character. As a rough barometer, anyone who goes on Joe Rogan to present their hidden scientific truth of the universe while making an unsubstantiated claim to have "95 patents" is probably worthy of a few giggles. For a full debunking, read on...

Taking his claim "1 times 1 equals more than 1" for example, Mr. Howard may very well be perceiving non-Euclidean space that the rest of us are missing entirely. Certainly if we change the axioms of mathematics then we can jury-rig this claim to be true, but at that point the claim becomes non-falsifiable, and not particularly useful.

Similarly, the claim that "every element in the periodic table has a musical key, and that H, C, Si, Co, Rh are all in the key of E at different octaves", the "octave" seems to be an analog of the periodic table "row" (how many electron shells the atom has), and the "key" seems to be roughly-speaking the relative "column" (relative electronegativity of the valence shell) with E apparently being a "half-full" valence shell. So if we take the "weak claim" that "musical tones are a nice labelling scheme for the elements", it doesn't contribute any new secret knowledge that isn't already well-understood by mainstream chemistry and represented in the standard Periodic Table. On the other hand, if we go with the "strong claim" that elements actually have musical tones, certainly there is no evidence of this in terms of atomic vibrations, photon emission/absorption spectra, etc. More likely Mr. Howard has some form of synesthesia--but again, just because one insists that "the number 4 is green", or that "the month of August tastes like tomatoes" does not make it so.
