Hi there

We are giving away some cool gadgets this week:

  • Google Nexus 7 Android Tablet
  • Swann Micro Lightning Gyro Balanced Remote Controlled Helicopter
In the competition we promote the advertising campaigns of FNB Retail uncapped ADSL, HP Supplies Online, FNB Retail Consumer Smart Devices Deal, Microsoft Office365 and Diablo.

TO ENTER

  1. Click on the banner shown on the top of this forum to see what the company offers
  2. Post something from the company website (hence where the banner takes you) which you find interesting or of value
  3. DO NOT post any URLs
  4. You may enter 5 times – once for each of the 5 banners
The competition will end on Friday 20 September 2013, and standard competition rules apply.

Promotion explained: This giveaway forms part of a value-add to companies which advertise on MyBroadband. They support the site, and in turn we give them additional exposure by asking you to engage with their campaign. They do not pay for clicks (all campaigns are set rate or CPM), which means that the company benefits for free, and you can win cool prizes. Everyone benefits :)

I know this is a Reuters-sourced article, but this is a horribly egregious error (and sneaky with it), and people could stand to LEARN (dammit!) :p So, the Silk Road/Bitcoin article has
“They’re going to be pouring all over his records, getting subpoenas for every piece of data and account he has ever used and trying to figure out who all these different dealers are,” said Bruen. “People are jumping ship.”

You pour water, and pore over documents, so that should be "they are poring all over his records".
 
This may be in a bit of a grey area (but it's a whole lot closer to black than white) but the writer of the WLAN 802.11ac technology article screwed the pooch five times with
More spatial streams via more antennae: 802.11n introduced multiple input /multiple output (MIMO) transmission systems, which uses up to four antennae for transmitting and four antennae for receiving (4×4). This allows a single bit stream to be divided into four different streams to be transmitted simultaneously, and then aggregated back to the original bit stream at the receiving end. 802.11ac increases this to up to eight streams via eight antennae (8×8).

Multi-user MIMO: 802.11ac introduces the technique of an AP using multiple antennae to transmit simultaneously to multiple clients. For example, a 4×4 AP can transmit simultaneously to four 1×1 clients.

Yes, there may be more of a US bias for antennas over antennae in technical usage but it's hardly exclusive, and when the local tech industry and community use ~s instead of ~ae, it seems to be the commonly accepted usage. Besides which, it's an effective differentiator. Also, the zeitgeist leans towards biological antennae and constructed antennas.

And then, actual errors:
Wider channels: 802.11n introduced 40 MHz channels, which improved rates over previous 20 MHz channels. 802.11ac introduces 80 MHz channelsnow, and 160 MHZ channels in a next wave. Higher modulation and coding schema (MCS). 802.11ac introduces 256 QAM, which allows more bits to be encoded in a single symbol. This can provide up to a 33% improvement in bit rates.

That should be "channels now", MHz, and the orange-highlighted portion just doesn't scan, maybe that should be "Higher modulation and coding schema (MCS): 802.11ac introduces 256 QAM".
