I feel like especially when someone is asking something from me, they sort of have an obligation to make it clear, early on, what they're actually asking for. Tangential but related; when I used to work for BigCo, I would get old acquaintances message me on LinkedIn. They would act like they're really interested in my life and I'd interact, and then after a day or two they would ask me for a referral for a job, I'd d…

That is the way to do it. And IMO it should extend to all business communication. I hate getting "hey" in my DMs with no other context. Like...."hey? whats up?". Just get to the point, the day is too busy for this.

Yeah, if you're doing something asynchronous, exploit that fact!

When I message someone on Slack, I usually do something like "Hey! I was wondering if you could help me with..."

There's no need to add an extra blocking factor with this.

There's a manifesto for this: https://nohello.net/en/

> I don't get why RockChip doesn't budget the money in the business plan to fund full driver support for at least some of their more capable chips. I guess maybe too many of these chips are used in non-OS contexts to be worth it? They have drivers in most of these cases; at a bare minimum the silicon was tested by the DV teams, and that generally includes running drivers.[0] The issue is getting drivers upstreamed ra…

> First off, the drivers in the vendor BSP are simply not at a quality level that would be accepted upstream. You're quite right, morally and practically. I can't help but wonder though, if the like of Rockchip or other big faceless chipmakers released whatever inadequate source they had, that it wouldn't somehow end up in a nice upstream high-quality driver.

The source is available [1]. The problem is that it's an unmerged fork of the 6.6 kernel.

This effort seems less of a "Help us by buying our product" and more a plea for contributors as a FOSS effort, they want to do things like this: "Collabora + Flipper: Opening up the RK3576" https://www.collabora.com/news-and-blog/news-and-events/coll... , and are basically looking for developers and other technology enthusiasts to help them both with the projects themselves, and also try to network (socially) their w…

If anyone’s wondering why this replier is so angry, it’s because they spent a lot of time arguing with people further down the comment section over whether this article is too heavily written by AI. (I'd say it is.) It probably irked them to find the top comment had no mention of AI, but is still getting at the same root problem… the article is 2-3x longer than it could be, with lots of rambling and repetition, so it…

Funny that I feel this same way around articles published on The New Yorker but have never once seen the same criticism about their articles. Usually it’s praised as great writing in the comment sections wherever it’s discussed. This observation predates AI by quite a while. In this case, I think its repetition is on purpose. I heard of the Flipper One recently and assumed it was a new version of Flipper Zero. I didn’t understand it was different. Even after they asserted it was at first, I didn’t fully grasp it until later in the article where the Layer 0/1 infographic was presented. This is quite simply consumer education around their products. Repetition isn’t always a bad thing, sometimes it helps and sometimes it’s done purposely.

Some of this stuff you need to probe with very, very expensive equipment and fine-tune parameters, and to make it worse, RF performance also depends on the composition of the PCB layers, the amount of vias, hell even just rotating an unrelated component on a PCB can affect the RF performance of nearby components or traces. If you're into that, Hans Rosenberg has some darn good yt videos [3]. RF is a world of black ma…

I understand that much, but we have the firmware - we don't have to extract it or rebuild it in a white-room? Or is some of that information baked into the firmware that we cannot flash? I've reversed some camera sensor binary blobs recently and I didn't have too many issues, only took a really long time (5 days) of running in a loop until source matched the original (sematically). I parsed the blobs into an intermed…

> I understand that much, but we have the firmware - we don't have to extract it or rebuild it in a white-room?

You need a testing lab with easily 500k worth of gear and construction cost if not way more than that to probe the data buses and obtain the parameters, we're talking about 1.6 GHz (RAM) or, and here it gets dark, up to 16 GHz (PCIe) frequency here. A scope alone that's capable of digesting such signals runs north of 250k from what I hear, you need calibrations, test probes, the room needs to be extensively shielded in order to not get disrupted by RF emissions of, say, the microwave two floors away.

And the people needed to do that are short in supply. As said, RF is dark arts, and I'm a mere radio amateur - I know people who do own such class of hardware though. They make bank. And I stay away as far as possible from anything higher frequency than LoRa. Don't got the brains for that.

IIRC the original scope was the 8 most common tasks that literal Swiss soldiers did. that was their scope. sewing and maintianing clothes was one of them, for example, so thats why it has a punch. They'd need to be able to open cans, as that was the most common long term ration, and they'd need to be able to maintain their rifles which had screws, thus screwdrivers. a version with a wine bottle opener was made for of…

>IIRC the original scope was the 8 most common tasks that literal Swiss soldiers did Never realized opening a bottle of wine was so common to Swiss soldiers

The comment you’re replying to already explains why they have a corkscrew… I’m used to people not reading the article they’re commenting on, but this is the first time I see someone not reading the comment they’re replying to.

Re: the on-device AI, most people don't know what they don't know. And they don't know that there's dozens of on-device AI applications that already exist in the real world using tiny AI models. ESP32-S3's have been doing on-device AI for years . That's a 240MHz processor with 512KB SRAM, 16MB PSRAM and no GPU, and AI works great on it.

> AI works great on it. Define AI, and define "great"

I can't define AI, but I can define "great"

Great is the not-sucking.

If it is great, then it does not suck. If it sucks, then it is not great. To be great is not merely to be good, it is to actually not suck. Then you are great, in the most minimal, barely clawed yourself over the line way.

I have a Flipper Zero and these guys made a great tool, so I clicked this headline because it said "we need your help". After scrolling two pages I couldn't find what they need my help with, though. I scrolled to the end and couldn't find it there either. If I'm being honest, I like their stuff but not enough to dig through 8 pages of content to find out what helping means.

> ditch binary blobs entirely I agree there is not much of a clear call to action. As a firmware engineer who has worked with bluetooth amd wifi, this is a key phrase. It’s also a big fantasy. FCC compliance is a big headache, and part of why people buy a given chip is the FCC certification comes with it. For instance, if I throw an ESP32 into a product and use wifi, I don’t need further certification. That can only…

> if I throw an ESP32 into a product and use wifi, I don’t need further certification

Sounds like nonsense to me, at least from past reading of the regulation. These devices are supposed to be type-accepted-- your entire product is supposed to be certified.

Is the FCC really allowing this? (not that I'm complaining, the FCC certification burden is outrageous).

I am looking at this now, and to be frankly it not having a keyboard makes this uninteresting for me. Either a slide one (like old Linux Nokias), a small blackberry like one or one like the phone in Die Hard 4. Having no keyboard reduces a lot what I can do on the go vs a GPD Pocket.

I'm guessing it's the last part that made me seem angry, I'm not though, just human, and tired of people who say they want to help yet seemingly reading is too much. A bit of straightforward language seems more effective at communicating this, than dancing around the issue. And why on earth would I care if the top comment mentions AI? I don't even read HN co…

Personally I detest AI generated creative content with every fibre of my being any will gladly rubbish on it without bothering to read the slop first.

Same, nothing I said is in conflict with that. I just equally despise HN comments vaguely complaining about maybe AI written content.

Yeah I agree with you there.
