Frequent flyers will soon be able to stay online whenever they fly after Virgin Atlantic revealed details of a new in-flight Wi-Fi connectivity plan.

The airline has confirmed its entire fleet will now be able to get Wi-Fi during flights around the world, with all 39 aircraft now connected, even on transatlantic flights and those carried out by Virgin's US partner network Delta Air Lines.

Facebook ad metrics are facing scrutiny after it transpired the social network is overestimating the potential audience advertisers can expect to reach. A senior analyst from Pivotal Research Group points out that Facebook's Adverts Manager tool suggests demographic figures that exceed official numbers.

For example, advertisers are told that they could hit up to 41 million 18- to 24-year-olds in the US, but according to recent census data only 31 million 18- to 24-year-olds live in the US. The discrepancy is not isolated, as there are similar instances of inflated potential reach suggestions for various age groups in the US, UK and Canada.

If you've ever thought that Facebook knows a little too much about you, here's something that's going to do nothing to dislodge that fear from your mind. Using a combination of government census information and data from satellites, the social networking giant has mapped the location of people in 23 countries around the world.

In all, Facebook knows where millions of people live down to an accuracy of 5 meters. All of this has been made possible by a mapping technology developed by Facebook to help it see how people are distributed across the globe to determine how best to supply internet to different parts of the world.

Nine years after going open source, Reddit is archiving the source code for its website and mobile apps. The source code will still be accessible, but will no longer be updated -- Reddit cites concerns about competition as one of the reasons for the change in direction.

But Reddit is not completely turning its back on open source. While it will no longer be possible to access the full source code, it will still be possible to access a limited number of small codebases -- such as baseplate, rollingpin and mcsauna. The site says, "those who have been paying attention will realize that this isn't really a change to how we're doing anything but rather making explicit what's already been going on," but users are not convinced by the explanation.

When you type a URL into your browser’s address bar and hit enter, there will be a slight delay while the software asks a DNS (Domain Name System) server for the IP address of the site in order to be able to load it.

Switching to a faster DNS server could shave milliseconds off the lookup time, and ultimately speed up your browsing. You can do this manually, or there’s a simpler option.

Redesigns are tricky beasts, almost inevitably dividing opinion and leading to questions about why things couldn't have just been left alone. Running the risk of a double whammy of complaints, YouTube has rolled out not only a redesign of its sites, but also a brand new logo.

Both the desktop and mobile versions of YouTube have been treated to a new look. It's the redesign that has been beta tested on users for a few months, and with a few extra tweaks, the company is ready to give everyone access to it. While a fresh lick of paint for the site and apps was expected, the new logo is rather more of a surprise.

If you have yet to be granted access to Facebook's trip-down-memory-lane feature, On This Day, now you're in luck. The social network has opened up the feature to all of its two billion users.

At the same time, Facebook is introducing some interesting extras, and taking steps to ensure that more negative memories are not surfaced for you. On top of this, there are new seasonal memories and new ways to celebrate friendships.

Saturday night's fight between Floyd Mayweather and Conor McGregor is set to be the most pirated sporting event in history. In the US, it's Showtime that will be airing the fight as a pay-per-view event, but links to live streams are already popping up online ahead of August 26th's event.

The broadcaster has already taken pre-emptive court action to kill a number of pirate streams but it is -- predictably -- turning in to a game of whack-a-mole, and once the fight kicks off it will be near-impossible to close new streams that have popped up and stop people watching for free.

Some online events unite people -- such as the recent solar eclipse which was streamed online by millions of people unable to see the spectacle in person. Another uniting event occurs when a major website goes down... like Facebook.

If you've tried to visit the social network today, you may well have found that the site doesn't load. "Is Facebook down?" you may ask, and you're not alone.

Verizon, Ericsson and Qualcomm Technologies have managed to exceed the Gigabit speed barrier over LTE.

Together the companies were able to reach download speeds of 1.07 Gbps during an Ericsson lab trial using the Qualcomm Snapdragon X20 LTE Modem which is the first modem to support Category 18 LTE speeds.

Facebook's Safety Check feature has been around for some time now, giving people the chance to use the social network to let friends and family know they're OK in the event of a natural disaster or other catastrophe.

It is Facebook that decides which events warrant activation of Safety Check, and until now it has also been down to the site to advertise the feature to users so they can either mark themselves safe, or check up on others -- but this is about to change.

Facebook won't -- usually -- hand over your private messages to anyone after you die. The social network has used a new blogging series called Hard Questions to reveal just how it handles deaths of its users.

The site's director of global policy management, Monika Bickert, says that Facebook aims to not only be sensitive, but also to respect the wishes of the deceased. After death, accounts are memorialized by default, but everyone is also free to create a "legacy contact" who will be able to mange their account in the event of their death. But Facebook is, it says, also keen to protect the privacy of survivors.

As any Facebook user will know, clickbait is rife on the social network. A very common technique used to drive traffic to ad-laden websites is to embed fake play buttons in images, or post videos that are actually static images.

Facebook is clamping down on these practices in a bid to tidy up users' newsfeeds and avoid people being transported to "low quality websites" set up by spammers.

On Monday August 21, people across the US will have the chance to witness a total solar eclipse. While there is a great deal of excitement about the phenomenon, viewers need to be careful to use special eclipse glasses (not just sunglasses) or some form of projection technique to avoid serious eye damage.

But perhaps the safest option is to watch the eclipse on your computer screen or mobile. Twitter has teamed up with the Weather Channel to provide a live stream, so even if you're not in the path of totality, there's no need to miss out.

Following the violence that took place in Charlottesville last weekend, technology companies have done everything they can to distance themselves from neo-Nazis, white supremacists and other right-wing groups. It led to numerous companies dropping right-wing sites such as The Daily Stormer, which was ultimately pushed to the dark web.

Digital rights group the Electronic Freedom Foundation (EFF) -- well-known for speaking out about privacy and legal issues -- has criticized the ban on neo-Nazi sites and groups saying it poses a threat to free expression online. Google, GoDaddy, Cloudflare, Reddit and Facebook are just a handful of technology companies to have banned The Daily Stormer, but EFF says that "no one -- not the government and not private commercial enterprises -- should decide who gets to speak and who doesn't."
