Show HN: I added a photo gallery to my e-paper smart display
I keep iterating on my e-paper smart display. It's still a side project I am working on after work. I think it has come a long way since I first posted about the idea here on HN - and I plan to keep going with it!

My newest addition is a photo gallery app for the display!

Users can upload pictures from their smartphone and show them in random rotation! The photos are converted to black and white, using dithering to achieve the illusion of grayscales.
The pay is largely going to be set by demand. But also: The sector has been ramping up salaries since the mid aughts, and I've found different people have different ideas of what the inflection point was in technology where it become prestigious/highly paid.

For me, I feel like things really heated up in the the 2010s. But there are others who I think would walk away from this industry if they got paid, adjusted for inflation, like it was 2015. As someone who cut their teeth in the wake of the dotcom crash, I look at the early 2010s as the halcyon days even tho pay got A LOT better - but I feel like that period struck a really good balance. If all you know is the white-hot market of 2019-2021 I suppose everything else looks like a massive downgrade.

(Not implying any of this relates to your experience, just giving my 2 cents)

+1 : Heterogeneous/Non uniform core configuration always require a lot of very complex adjustment to the kernel schedulers and core binding policies. Even now after almost a decade of big-little (from arm) configuration and/or chiplet design(from amd) the (linux) kernel scheduling still requires a lot tuning for things like games etc...
Adding cores with very different performance characteristics would probably require the thread scheduling to be delegated to the CPU it self with only hint from the kernel scheduler
It just sounds like they’re turning the single plat aspect into the selling point that it was built for the audience’s platform as opposed to some crappy multi-plat app.

I’d say that’s a good call for a $200 app. The HNers showing up here to announce that they closed the browser tab couldn’t run the app anyways lol.

In retrospect.

I see houses bought in 2006 and sold in 2015 with a loss (in capital cities).

The thing is, if you entered the housing market in 2006 you would be set significantly back. If you entered in 2009 you would be at advantage.

People are betting on which of these cases we are in now.

Anyhow, when people think you are nut for buying, it is probably the right time. Currently the FOMO is real and everybody are recommending me to buy. I take that as an indication of over optimism, which is factored into the price.

Yeah, but a lot of people do menial tasks like human OCR, just like once upon a time humans were literally called computers and had such a job.
Mental health conditions are typically defined by a collection of symptoms though, aren't they? I am not suggesting there is no underlying cause, but our ability to detect and quantify that cause is lacking, so defining disorders based on a collection of symptoms is what we are mostly left with in many cases.

I too, have hated how Swift has become a mega-language and is trying to be too many things at all levels of the stack. I tried following the Swift-Evolution group but was frustrated with all the proposals on it. I'd say too many smart people have had a hand in its evolution.

Was your point that that goes for SQL?

One nifty thing with SQL is that you get all the threading/remote processing for free without having to think about it. That can be pretty hairy to write yourself.

> What is “the underlying process”?

IMO -

The simple ones: advection, latent heat release/absorption from water changing phases, and the Coriolis force. If you need an AI for this, please take a course on differential equations.

The hard ones: droplet/ice crystal formation, cloud feedback on radiative transfer, evaporation at air-sea boundaries. If you can train a model for these processes, please, please tell someone.
From a slightly different perspective, some people like these tasks :). That's part of the mindset of being a good data engineer, for example - I rarely have a problem coming up with my own set of queries to try out a new database or dataset. But I'm also not really interested in a lot of SWE-specific things.

Maybe this just isn't something you really want to dive into. That's ok!
> The Central Limit Theorem (which says if we add a bunch of random numbers together they'll converge on a bell curve) only guarantees that you'll get a normal distribution. It doesn't say where the mean of the distribution will be.

That's kind of overstating and understating the issue at the same time. If you have a skewed distribution you might not be able to use the central limit theorem at all.

The difference is that an LLM isn't very good at saying "I'm a fucking idiot" and changing it when asked to double-check (unless you handhold it in the direction of the exact error it's meant to be looking for). Humans recognize their own hallucinations. There's not really any promising work towards getting AI to do the same.

Which dialect of Portuguese are you referring to?

I'm a fluent second-language Spanish speaker and have had a lot of success communicating with native Portuguese speakers, but only Portugal Portuguese and various African Portugueses. I can't understand Brazilian Portuguese at all.
"Code smell" as a programming term is often a red herring that causes conflicts within development teams (I've seen this happen too many times), because anyone can call anything they don't like about a coworkers code as a "code smell". Your comment is a "code smell". See how easy that was?

And "code smell" doesn't apply in a similar or metaphorical way towards cable modem support personnel. Those people aren't supposed to know how to escalate a case of a customer bringing in suspected hacked modem. If they did that for every idiot customer that brought in a "suspicious" modem, the company's tech support staff wouldn't be able to get anything done. 99.999999999999% of the cases would not in fact be a hacked modem, so there really shouldn't be any pathway to escalate this as a serious issue.
What is a very powerful computer? Would any laptop no older than 10 years with integrated graphics have trouble rendering these?
I'm running a quite old CPU currently, a 6-core Haswell-E i7-5930K. Disabling HT gave me a huge boost in gaming workloads. I'm basically never doing anything that pegs the entire CPU so getting that extra 10-15% IPC for single threaded tasks is huge.

And like you said, the vulnerability consideration makes HT a hard sell for workloads that would benefit (hypervisors).

That i7 is a huge downgrade from what I was running before (long story) so I'm looking forward to Arrow Lake and I like everything I've read. In addition to removing HT, they're supporting Native JEDEC DDR5-6400 Memory so XMP won't be necessary. I've never liked XMP/Expo...

Because there's basically no design downside to having a higher power rating than needed, aside from BOM cost. If you're ordering a bunch to have on hand, you should just order the highest power rating you're likely to need in that size.

For me, that means that my 0402s are all 1/16W, 0805 are 1/8W, 1206 1/4W, etc. And all of my through-hole resistors are 1/4, because the wire stock plays well with breadboards better.

There are probably 1/4W 0402s out there, but that's definitely a specialty piece. I'm seeing 16 cents a resistor/each for a 1 MOhm 1/4W 0402, which is about 4 times what I'd expect to pay for a 1/16W of the same resistance and package.
What if Canada just decided that copyright protection on the type of material that America streaming companies make crazy profits from was only valid for 25 years?

Like let's be honest here, these companies only make money because of an onerous protection racket that was lobbied for by the likes of the RIAA and MPAA.

Canada is just deciding that they want their cut. That's all it is. There's no good guy here.
it is not exceptional though. this is why Medicare does not cover it. they already ran the numbers
There’s several benefits for an Apple TV to me:

1. Has the vast majority of streaming services first. Many streamers deprioritize web and other platforms.

2. Really solid accessibility options that aren’t available on other platforms. I use these quite frequently.

3. I am in a few film guilds and the screeners apps until recently required an iOS or tvOS device, or a clunky website. The tvOS experience for voting screeners is significantly better.

4. Lag. Pretty much every other streaming box has lag when navigating a UI. The Apple TV isn’t perfect but it’s night and day for me.

5. HomeKit + Thread makes for it being a decent (but not great) smart home management system

And I know you’re dismissing convenience, but it’s a huge factor too. TV time is about no-fuss and unwinding.

With the Apple TV, I can use my phone for text entry and password management. I can use it to synchronize playback with friends and family.

Those are all possible on other devices, but convenience is a massive factor.

Dr. Pepper forever! Several years ago I started drinking Dr. Pepper with Cream Soda[0]; it's really good! The strawberry version is also pretty good IMO.

Pepsi has this weird taste to me, so I'm not shocked if it's falling out of favor somewhat. Of course, that's all subjective, and I'm sure some people can't stand Dr. Pepper but love Pepsi.

Accurate grade school comprehension 100% of the time IS superhuman. However, I agree that some people probably half ass it and do worse than their best. I think it is fine to be frustrated when someone does a shitty job for you.

I think the interesting point for me is the "authority", or social part of it. This seems to be a projection from the patient, and then they get upset that doctors dont reciprocate.

This is what strikes me as screaming at the clouds. Respect, authority, and trust are in the eye of the beholder. To the degree that there is a mismatch between expectations and reality, the error is on patient for projecting a false reality. Then they are angry when reality doesn't match of with their imaginations.

I also think it is weird to place such broad expectations on doctors as a class of people, as if they are all the same. Some are great and some are shit. Most are somewhere in-between.

If the anger is that doctors are paid more, that doesnt make sense to me either, because it is just supply and demand, not some moral social quality of doctors that make them better humans, and therefore deserving of more luxury or financial success. It seems a weird special expectation that people have constructed for doctors. In contrast, Nobody has an elevated moral expectation of bankers just because they make more money.

I just think that people would be happier, and perhaps get better care if they based their expectations in reality.

You shouldnt view health as a responsibility you can outsource to a doctor. No doctor will care about your life more than you do. Doctors come in all levels of competency, and it is your job as owner of your body to shop around. Some people desperately want blind trust and freedom from responsibility, but if they go down that path, they are embracing a fantasy,

This is why I left windows recently[0]. When you design an OS that doesn't respect the user's choices, you are no longer in control of the OS. Windows 11 shifted to trying to force people to use Edge. You can't even change the default browser in many cases without some serious work.

And the FTC is going after anyone but Microsoft for anti-competitive behaviors. The desktop world looks bleak for people that depends on Windows.

Reminds me to revisit displacement mapping — probably not going to be a replacement for the problem that author is trying to solve but simpler and kind of fun.

I wrote a kind of cool music visualizer for SoundJam perhaps 25 years ago I called "Eclipse". Input data was an array of levels (probably integers) across some range of audible frequencies — a left and right channel.

Think of the eclipsed sun with corona ejections — that was what I was going for. The music data was the "ejections". The frequency of the data determined where around the disc of the sun it would appear.

Over time the ejecta moved away from the sun and soon disappeared as they "cooled" to black — the initial color of the ejecta being white for the strongest signals — yellow, orange, red, brown when weaker. (Think of the black body curve.)

I had to keep a circular buffer of the sound data values (an array of arrays) large enough to represent how much time the ejecta would "live" before disappearing to black.

In any event, the whole display of the "eclipse", ejecta, was just a displacement map. I had pre-calculated a bitmap where the value for each "pixel" was an offset into the buffer of sound level values. "pixels" close to the surface of the sun would have offsets to the new data coming in, pixels further out would have offsets into the tail of the buffer that was about to expire. With the circular, radial aspect of the ejecta, there was some math involved in generating the displacement values in order to map from essentially a radial space to a cartesian one.

With that established as described, the main loop simply pulled in new sound values, over-wrote the oldest values in the circular buffer with the new and then iterated row and column-wise over the displacement map, grabbing the corresponding sound data value, mapped it to a color in a fixed palette and pushed that color into display buffer.

Although not as "flashy" as other visualizers, there was I thought a calm beauty to it. And it very much represented the music data (you know, as opposed to later visualizers where, even when presented with silence, they seemed to be unable to settle down).
Gravity can be modeled as "things on the earth's surface accelerate downward at about 10 m/s², regardless of their mass". This works very well. Gravity can be modeled as "planets orbit the sun according to Kepler's laws". This also works very well.

Newton realized that these phenomena could be explained as arising from the same underlying process of an inverse square law. This is a much more useful model, and allows predictions that allow us to do things like space flight, even if it is not complete.

> but you are still modeling the world

No. That's precisely the issue here. NN's do not "model the world" in anything remotely like the traditional meaning of that term.

Modelling the world historically means identifying objects/phenomena and proposed causal relationships between them. Without the relationships - e.g. if we add heat to the system, it will move more - there's no model. You may still be able to get predictions, and they may still be useful, but you are not defining a model.
> Why haven't companies simply adopted the YYYY release scheme or YYYY.NN?

Personally, I prefer the more traditional version numbering scheme (AA.BB.CC) because it actually tells useful information around the version. But if the choice is between your suggestion and the nearly nothing that is in vogue now, I'll take your suggestion every day of the week.

I think that the deprecation of useful versioning information is because so many companies want to do continuous releases rather than discrete versioned ones. While I very much think (as a user) that continuous releases are a Bad Thing and I wish devs would move away from the model, if we're going to have them then the traditional versioning scheme does become unworkable.
There’s also part of, good designs don’t depend on high precision components. I think TAoE emphasized that. For high precision one can use trim potentiometers or maybe even digital potentiometer with an ADC at the other side to measure and get as close as possible, but otherwise depending on resistors for high precision is kinda rough (I’m think like an RC circuit that need a very specific resistance to meet some specific timing requirements)
