I suggest uMatrix:
https://addons.mozilla.org/en-US/firefox/addon/umatrix/

In whitelist mode it blocks all 3rd party requests and you can block 1st
party requests too.

GNOME does not force you to use Wayland. I don't know where you got this
idea from. Wayland is still supported experimentally (X is used by
default, Wayland support is quite buggy) last time I checked. As for
systemd, GNOME requires logind, but not the entire systemd package.

On that note, I'd recommend for Firefox (if that's what you use) an
extension called QuickJS, which gives you a button in the toolbar to
enable and disable JavaScript.

To be clear, I wasn't suggesting trying to do your work on an A20 card,
or anything else you produce in the next few years. That would be
absurd. More that maybe it would be a good idea to optimize things so
that you don't have to keep upgrading and eventually an EOMA card of
some sort can catch up.

It seems even just managing to reduce your screen need so that a 1080p
screen would suffice would be a huge help. Then you could just focus on
getting a multi-core system with lots of RAM and a big hard drive (or SSD).

By the way, have you considered turning off swap? Linux will
automatically terminate programs when there just isn't any RAM left, so
that would at least prevent your system from slowing to a crawl. Also,
using swap on an SSD is probably really terrible for the SSD. I don't
know if you can control what programs get closed when that happens, though.

 yes.  here's the key advantage of the RK3288 over the RK3399 right
now: it's been around longer.  i'm just writing up an update at the
moment, but basically the fact that the RK3288 has been around for
nearly two years means that there's such a stupid amount of "metoo
HOWTOs" out there it's actually decreasing the informational
signal-to-noise ratio on setting up an RK3288-based system.

 it's got mainline u-boot support, it's got mainline linux kernel
support, it's got nearly a dozen different products out there, it's
got PCB CAD files that have "accidentally" made their way onto the
internet and can be picked up for a whopping $24 on taobao.com, it's
got the Technical Reference Manual available online... all without an
NDA.

 now, whilst it would be *really nice* to do an RK3399 board, although
USB3 would be a nice-to-have, the performance/watt figures for the
arm64 cores are a whopping FIFTEEN PERCENT lower than for the 32-bit
ones right now.

 so my feeling is, it would be a good idea to wait a year, see how
things progress with the RK3399, see if it becomes as popular, and in
the meantime keep a lookout for both entirely libre processors as well
as some that can handle 8GB of RAM.

 yeah :)

 gotta redo that.  with 4k displays now prevalent, i think it's going
to be necessary to add either MIPI, eDP or both to EOMA-200.

Re: [Arm-netbook] new development laptop needed, looking at dell xps 13 9350

[Julie Marchant]

Just my 2 cents:

From what I've been gathering, Luke, this is the situation: you are used
to a very high spec setup capable of really large amounts of
multitasking and don't want to give up your current way of doing things,
so you are looking for a new laptop capable of this. There's nothing
wrong with that if you can find it. But maybe it would be worthwhile to
adjust your workflow so that it doesn't need an ultra-HD screen and
16GB+ of RAM? There must be some way you can achieve that.

These are the thoughts I have, in particular:

* From what I understand, you use a DE that basically tiles all of the
programs you have open into whatever screen space you have, right? Have
you ever tried GNOME? That might be a good replacement for that if you
can get used to it.

* Is it really necessary to have all of those programs open at the same
time?

* Is it really necessary to use Chrome or Firefox? There are more
lightweight browsers out there, including text-based ones like elinks.
Disabling JavaScript can also help a lot with performance in general.

* What if you had one laptop for openscad and other heavy or important
stuff, and another, cheaper laptop for Web browsing and other stuff like
that?

* I'm wondering about that SSD. Are hard drive speeds really so bad that
you need one? Big SSDs are much more expensive than big hard drives. My
experience with a hard drive is that it's mostly start-up times that are
affected, so what I tend to do is log in and then go do something else
while everything loads, and then use the suspend to RAM feature if I
need to conserve battery for a short period of time.

I'd also like to point out that learning to live with less than you're
used to would be really good for your public image, since after all, the
hardware you'll be selling for quite some time is nowhere near those
capabilities. ;) As it is now, for example, if someone says that what
you're selling isn't good enough, they have you as an example to back
that claim up. But if you manage to reduce your needs and eventually
meet what EOMA hardware can achieve, then you would have your own
example to refute that, and you would even have experience that you
could use to advise people on what sorts of changes to make to the way
they do things. Food for thought.

 nice idea... can't do it.  remember, i would have to carry the mini
desktop as a server, plus its power supply, plus network cables, in my
backpack, setting it up at the factory, or at a client, or at a hotel,
or a supplier, every single time.

 plus, openscad, which is heavy on the 3D OpenGL side, simply wouldn't
work over X11.

 damnit if they could do up to 16GB of RAM instead of being restricted
to 12 i'd consider it, based on the lower price.

 tried it: it failed spectacularly, trashing the performance
completely for general use, and, worse, actually made matters worse by
taking up real RAM.
