Cortex-A53 is a very slow in-order core. Think Pentium 1 -level IPC. Eg: it can dispatch at most one multiplication, and will stall the entire pipeline for a few cycles if you try another one soon after. I doubt this is going to perform well

#122Does anyone know if there custom OS has a screen reader? I'm totally blind and this is priced at the point where I'd like to play with it assuming it's usable for me.
I would love to give you a definite answer, but only way to know for sure is to test yourself. PineTab can run any ARM OS, so you can install one that you have positive experience with. These OSes are touch-optimized and recommended: UBPorts (community-driven Ubuntu Touch) postmarketOS Arch Linux ARM I know that desktop Ubuntu has screen reader (Orca) installed by default. No sure about Ubuntu Touch. My Google-fu sho…
You should be able to run a standard Ubuntu if you don't aim for touch-driven interaction; @jareds - do you?

Side thought... is it even cheaper if you just have displays/use an ESP to do http requests to a local server... guess depends what they have to do. I mean I think you would need a 32 to drive the display too vs. just an ESP01
I don't think they're capable of displaying a web page
Depends on the webpage, but the you can always render server-side

#124Absolutely incredible for the $120 price point. If they release a PineTab Pro in the future with 4 (or dare I say 8GB) of ram, I'd be all over it. At that point, I could really start to be productive. 2GB is a bit limiting for the modern web unfortunately, but there is a ton of potential here. I'm considering buying one to use as my main machine for this next year at Uni. Taking notes in VS Code/Vim would be fine, bu…
In case where the pine64 team is reading: +1 8GB RAM, 128GB MMC, USB-C for up to 300$ and it will be the perfect Microsoft Surface Go's contender I'm waiting for!
Unfortunately that looks unlikely to happen for at least a couple more years because they would have to use a whole new chipset and PCB

MBPs at some point switched to drawing power faster than it could be provided by the plug alone. Of course, you can't tell nowadays whether laptops will work without a battery, because most batteries are non-removeable.
I don't think I've ever seen that behavior with a MacBook Pro of any vintage -- and I've had an MBP of one stripe or another since at least 2007, using the date of the 2007 MacBook Pro gathering dust bunnies nearby -- except when I use the wrong power supply with it, e.g., a 13" MBP power supply with a 15" one, or my MacBook Air's power supply with any MBP now. I wouldn't doubt it's possible to draw more power than t…
I've run into it a few times with mine (2017 15" MVP, 3.1GHz Quad i7, 16GB RAM, Radeon Pro 560). I had an issue the other day where a virtual machine got stuck in a loop while testing some background jobs. Each time I tested it, another infinite job booted up. Eventually, I had like 30 of them running when I took off my headphones and heard the fans. Checked my battery and I was down to 65% despite being plugged in. I'm guessing that happened over the course of an hour or so.
I've also had it happen a few times when running unit tests for a different project in Docker, but that's likely just because Docker for Mac makes Electron look resource efficient.

I had 180W for my old HP laptop, and recently ~135W (or 170W) for Thinkpad W541. <100W adapters were mostly for potato laptops, until USB-C came into picture which supported up to 100W and now manfucaturers adapted (and probably wait for 200W PD).
Newer Dells pull 180W from a paired USB-C dock connector.
Nice to see workarounds.
I must say that I love that I just plug out the laptop power adapter and plug it into my phone (or mouse) and it charges. Even when it comes with lower performance of the laptop.

Even most middle-road laptops, monitors and phones have these disclaimers in the warranties AFAIK.
This amazes me. You could literally spend 2 grand on a machine and still be told its ok for it to be defective out of the box.
Well, if it's a high-res display then there's a lot more pixels so a greater chance of failure.
I actually really like this system and wish that I could trade-off further down the spectrum on quality. After all, to get a zero-dead-pixel device you just have to check in the second-hand market like people do for high-binned CPUs. The volume of true demand for those CPUs is high enough that there are retailers like Silicon Lottery that explicitly look out for that.
It turns out that most consumers don't really want a zero-dead-pixel guarantee though.

They don't subsidize anything here, so yeah, cost of shipping is really the cost to take a box from China to your house, pretty much. FWIW, when I got my PineBook Pro, DHL was literally like overnight from Hong Kong to the US. I think if you consider it part of the cost ($150 for tablet and keyboard shipped), it's still a pretty good deal.
Yeah, good point. Maybe I am just conditioned to subsidized free shipping from China.
That's going to end. The UPU agreed to let the US charge 70% of its domestic shipping cost to foreign carriers.

#129The further I get with computers the less I need. I’ve been teaching computer graphics using a 160 x 48 pixel display rendering Unicode Braille dots. It’s absolutely enough for:
- random colored text
- line drawing fun
- circles
- z buffers
- convex hulls
- ray tracing spheres
(Checkerboards are too noisy though, and no Newell teapots. Alas, if only my browser supported PBM, the graphics format of winners.)
So yeah, bring it on! Doing more with less feels like a journey worth traveling. I want one!

> 128GB MMC
Why MMC when there is NVMe?
