I have complex spectrum with N ponits
How can I conert this spectrum to spectrum with M points (M < N)?
sample rate in spectrum with M is same like in spectrum with N points

Worth it to get a g1 now?

I work at Radioshack and im looking to quit soon and i just just found out that we're going to be carrying t-mobile. I currently have a sprint vogue and im tired of a non hardware keyboard device. Would it be wise to get the g1 or the mytouch? Any advice will be welcome.

haha yeah, gotta love changing most of the signs in the store and wearing "flair." but 10 bucks a month for an employee line is unbeatable

i was worried more about the hardware keeping up with the software but basically, t-mobile says there'll still be support so im hoping there will be official roms released.

I wouldnt base my decision on that fact, the truth is the G1 doesnt have as much memory as the future android phones. Which means less features because not enough room for the new ROM's.
If i was in your situation i would wait till the end of the year to see what is released.
Personally haven't hearing the news that was told i wouldn't get a g1 now n get a touch instead or just wait on quiting till the new Android comes out

This is an ICC profile calibrated to view Television and Film using industry standards for viewing such content on the Nexus 7. At this time I don't believe there is any video player for Android that supports ICC profiles or 3d LUTS. Development appears to be lacking for color calibration...
Until such time this file is for reference only.
As a photographer, this is pretty interesting to me.
How did you calibrate the device without compatible software?

WiFi strength, range, and throughput

Rate this thread to express how you think the Sony Xperia XZ2 Compact's Wifi performs. A higher rating indicates that it has excellent range, throughput, and signal strength. Like when you're taking a dump in the bedroom upstairs, do your videos have to buffer or do they come through without interruption?
Then, drop a comment if you have anything to add!
it is faster than a z3 compact, with 405Mb/s from 1000Mb/s with one wall inbetween tested on a fritzbox 5490 with a theoretical 1300mb/s max. (on a pc i get up to 950mb/s)
a little bit further away (about 10 meter and with a floor and a roof inbetween and some metal) i get 191Mb/s. not that bad.
speedtest done with the speedtest.net app and both devices are connected on wifi ac and they are on the same spot when doing the speedtest. (and yes only one at a time and not 2 at the same time, so no interference)
I just can‘t search any wifi these days
just could not connect
Real use tests: Sony XZ2 compact Wi-Fi Qualcomm WCN3990 2x2 MU-MIMO
Hi all, sharing my 2 cents;
I did some real use test, but first, I gathered some info of the Wi-Fi Chipset that Sony XZ2 compact uses and their announced capabilities:

Wi-Fi Bandwidth support in AC: 20 MHz, 40 MHz, 80 MHz, 160 MHz. (256-QAM)
Wi-Fi Antennas: 2x2 MU-MIMO
Test Conditions:
Router: Netgear R7800 X4S (with OpenWrt 18.06.5)
Wi-Fi set: AC 5GHz with 80 MHz bandwidth
Users: 4 in Total; 2 Laptops (one doing YouTube, the other web-browsing), 1 Smartphone (doing social networks), 1 Sony H8324 for test.
Internet connection: 100 Mbps (download and upload)
Iperf: version 3, time 120 seconds, client Sony H8324, server Router R7800
