@JourneymanGeek Don't confuse with 802.11ad. 802.11ax is the next evolution in "normal" Wi-Fi. It increases throughput and adds features like OFDMA (used by LTE) to enable higher performance in networks with lots of users.

Large home networks with lots of IoT devices stand to gain considerably with 802.11ax.

Corporate networks, even more so.

Bob

@bwDraco most of 'IoT' doesn't have the processing power (nor use for) high-throughput tbh

Ramhound

@JourneymanGeek actually it's the next evolution to 802.11ac unlike ad, and af

bwDraco

Precisely.

Just checked my parents' phones - they don't support 802.11ac :(

They're on 5 GHz 802.11n.

My father's latest tablet doesn't even support 5 GHz and is on 2.4 GHz 802.11n.

However, since these devices don't use much bandwidth, it's unlikely that they would have a meaningful impact on network performance.

I have three MU-MIMO devices: my OnePlus 3T (1x1), Nexus 9 tablet (2x2), and the Bifrons netbook (1x1). At least I know they can all communicate at the same time without stepping on each others' toes because they can all share the same time slices on my 4x4 router.

It requires client support, although legacy devices will still communicate like they used to (technically known as time-division multiple access, or TDMA) without breaking MU-MIMO for capable clients. Essentially, MU-MIMO devices can still share time slices while legacy devices continue to get individial time slices.

Q: Java runtime bean for any property name

I want to have a JavaBean instance where using reflection to get/set any bean property (via methods setX() and getX() always succeeds, even if the underlying object did not define that property at compile-time. The type of the properties should always be a String, and should be stored in an int...

Bob

@allquixotic ow.

bwDraco

(MU-MIMO lets multiple devices communicate at the same time, using as many spatial streams as are available on each device and on the router concurrently, rather than just cycling through each device and wasting unused streams - this is particularly significant with quad-stream and higher routers in a world where client devices that support more than 2x2 are rare)

allquixotic

@Bob it's because my web framework doesn't support indexed properties in the form bean, so I'd have to write private foo_1; private foo_2; ... private foo_129340929; etc. and generate getters/setters for each one if I wanted to support an unbounded number of occurrences

the only HTML names I can generate for the fields are of the form fieldname_index

Hi!

Hey @BenN

how goes it?

bwDraco

Just composed this answer:

A: How do MU-MIMO routers handle non-MU-MIMO devices?

Devices without MU-MIMO (called single-user MIMO, or SU-MIMO) will continue to communicate with the router in a round-robin fashion, just as before. Any MU-MIMO devices can communicate simultaneously on fewer time slices. To illustrate this, let's take a home network with five 802.11ac client dev...

Ben N

Pretty good

bwDraco

Got to close a GitHub issue today that had been ongoing for a couple weeks :)

studiohack

well that's progress, right @BenN!

hey @bwDraco - I'm old now :P

I'm sitting avoiding dealing with a full cloud storage of 4ish years of cell photos, a full SSD, and Creator's wanting to install

All on a Yoga laptop with 4GB hardwired memory :/

Ben N

Ow :\

studiohack

yeah. and my fav browser is Firefox, but it is slow half the time

Hoping to clean up things with a fresh install of 1703

Tempted to re-build my desktop, but it's so hard to justify when I have no need to sit at a desk.

Ben N

I hear recent (and/or upcoming) updates are making Firefox a lot faster

I'm a Chrome user myself and am satisfied with its speed

William

I use firefox without javascript and chrome with javascript. Firefox is sadly slow but want to support it.

2:34 AM

Got a slow, cheap Lenovo laptop with 2 GB (!) of RAM, 64 GB of eMMC, and an Atom-type Celeron CPU. I've had to make lots of tweaks to limit paging and offload writes to external media (so as to optimize onboard storage endurance).

Jul 20 at 1:39, by bwDraco

Low-cost planar TLC NAND + DRAMless controller + low capacity + high write amplification (because the drive is often close to full) + low RAM + software not designed to minimize writes = bad SSD endurance.

I still have my main laptop, which has far more powerful hardware, but I managed to damage the CPU heatsink so I'm looking to replace it with a proper desktop (named Astaroth after the demon) soon.

(that machine is more than 3.5 years old and is struggling with the latest games)

I'd like a thin and light laptop with a Ryzen based CPU with significant on-chip GPU competitive with a decent dGPU, please, and I'd like it yesterday and for $2K or less

bwDraco

@allquixotic Where's Raven Ridge when you need it :(

allquixotic

although sheer practicality may dictate a proper dGPU die with physical separation from the CPU die

I think it's probably easier for current cooling systems (air or liquid + heatsink) to dissipate heat from two lower heat dies than one extremely high heat die

makes for more surface area to blow air over

so you'd get more perf out of a separate dGPU die

bwDraco

Also, separate TDPs.

allquixotic

but the machine would also probably be larger

bwDraco

(so CPU and GPU don't compete for power)

@bwDraco out office standard is a n3050 with 4gb of RAM and spinning rust.

bwDraco

@JourneymanGeek Desktop thin client?

Journeyman Geek

Laptop :p

bwDraco

Heh.

Journeyman Geek

It's terribad. Also not really my problem any more

bwDraco

N3350 here. More modern, but still very slow. RAM is also a major bottleneck.

Bob

3:12 AM

@allquixotic "competitive with a decent dGPU" of which generation?

Competitive with lower-end GTX 9xxM is probably possible

Competitive with GTX 10xx is ... harder

idk if newer mobile Radeons have come out yet, but the last few generations were ... not great

IME for web browsing and light gaming (i.e. not GPU-intensive) a m3-6Y30 is about as responsive as any full-(mobile) laptop I've used

not really tried anything GPU-heavy yet

That does not make it off-topic.

thanks night time for me bye

Ramhound

@Bob retracted my vote to migrate

Bob

@Ramhound Thanks.

The no-Android restriction has been relaxed a bit anyway (iirc, tablet questions are now allowed-ish) because the lines between them and "computers" are so much more blurred than they were 7 years ago.

But it's always been "if it interacts with a computer, it's fine"

so e.g. Android emulators, at least as far as they interact with computers, are fine

and per that meta Q above, chromeos are more or less counted as "computers", soooo.

@Ramhound @bwDraco Oh, didn't see that bounty.

Which also means they can't reply now. Hm.
