The humble HDMI cable is simultaneously brilliant, and a massive pain in the ass. Great for delivering HD video from your computer to a TV or projector, but a serious downside is the fact that, well, it's a cable. Who hasn't yearned for a wireless HDMI cable?

This is, effectively, what the Share Pro Mini Wireless HD Video Transmitter and Receiver Kit from IOGEAR is (GWHD2DKIT). It's a two-part piece of equipment that lets you stream audio and video up to 12m (40 feet) wirelessly. Best of all, there's no software involved, and no need for Wi-Fi.

Dropbox has revealed a new file sharing service that makes it possible to send files of up to 100GB.

The company says the service has been designed as a quick and easy alternative to configuring sharing and permissions, and it means that it is possible to share large files even with people who do not have Dropbox accounts.

Apple has disabled the Walkie-Talkie app for Apple Watch after a vulnerability that potentially allows for eavesdropping on iPhone conversations emerged.

The company says that it is not aware of any incidents of the vulnerability being exploited, and it has not shared any details of the security issue. Apple's short-term solution is to simply disable the app while it works on a fix.

Microsoft has emailed users of Remix3D.com to warn them that the site is to be retired in six months' time.

The site is a repository of free 3D models designed to be used in the likes of Paint3D, PowerPoint and the Windows 10 Photos app. The move is not entirely surprising as the writing has been on the wall for some time -- references to Remix3D were removed from Paint3D some time ago, for instance.

A few days ago, a security issue with the Zoom chat tool came to light -- a flaw that made it possible for Mac webcams to be switched on without permission. Despite seemingly suggesting that the flaw was in fact not a flaw, Zoom issued an update that grants users more control over the software.

Apple has also produced an update of its own which nukes the security hole. The silent update has been pushed out to users and is installed without the need for confirmation or user interaction.

IBM has closed its acquisition of Red Hat following the statement of intent back in October. Following the $34 billion deal, Red Hat will operate as a distinct unit within IBM -- and will be reported as part of IBM's Cloud and Cognitive Software segment.

For IBM, the deal means fully embracing open source as it looks to accelerate its business model within the enterprise. For Red Hat, it means expanding its client base and working with a big player in the enterprise cloud business.

Donald Trump's love of Twitter is legendary and often ridiculed; it is also the source of frequent controversy.

The US president is huge fan of ranting, raving and venting steam in tweet storms, but his famed love of sycophants also comes to the fore. Many people who have responded to his tweets critically have found themselves blocked. Now the US Court of Appeal says this is a violation of their First Amendment rights.

Timed to coincide with the back to school season, Apple has announced the latest updates to its MacBook Pro and MacBook Air. There's a special promotion which includes a free pair of Beats Studio 3 Wireless headphones with a qualifying purchase too.

A price drop for the MacBook Air means that students can pick one up for as little as $999 ($1,099 for everyone else) and benefit from the addition of True Tone to the Retina Display. The entry-level 13-inch MacBook Pro now features an 8th-generation quad-core processor which Apple says makes it twice as powerful as it used to be.

Time to dig out the tape and cover up your webcam. The Mac version of the video conferencing tool Zoom has been found to have a flaw that enables a website to switch on your webcam without permission, and without notification.

Despite having been discovered and reported to Zoom by a security researcher three months ago, the vulnerability is yet to be patched. In fact, Zoom disagrees that there is a security issue, although it does say that users will be granted greater control over videos in an update due for release later this month.

Microsoft has released a public preview of cloud-connected service Desktop Analytics.

Designed to help system administrators to keep Windows 10 devices up to date, Desktop Analytics integrates with System Center Configuration Manager. It allows for the quick and easy creation of app inventories to make compatibility checks simpler.

Offensive Security has released Kali Linux for Raspberry Pi 4.

The new build of the security-focused distro comes just two weeks after the launch of the Raspberry Pi 4, the most powerful version of the mini-computer yet. Offensive Security says that the new build takes advantage of everything the Pi 4 has to offer.

Canonical -- the company behind the Ubuntu Linux distro -- is investigating an attack on its GitHub account over the weekend.

On Saturday, hackers were able to break into Canonical's GitHub account and create a number of new repositories. Named CAN_GOT_HAXXD, the eleven repositories were empty and have now been removed. Canonical says that no source code was accessed, but it is not yet known who carried out the attack.

Advertising is the lifeblood of many websites, but at the same time it is something that few people are fans of. To stave off income-killing ad-blockers, an increasing number of sites offer per-article or per-month subscriptions that give people the chance to enjoy content free of ads while still supporting the sites they love.

Mozilla has a different idea -- "Ad-free internet by Firefox". The result of a partnerships with multiple online publishers, the idea is that a single, low subscription fee gives you access to a number of sites with the ads removed.

China's track record with privacy violations, control of the internet and control of its citizens is well known. But now anyone who has ever visited the country has cause for concern.

Enter China via the border crossing between Xinjiang and Kyrgyzstan, and you're required to hand over your phone -- unlocked. This would obviously lead the owner to expect a little rooting around by officials, but an investigation has found that border officials are actually installing secret spy apps on iPhones and Android phones to scour emails, texts and other data stored on devices.

Some Mac users -- who, thanks to Boot Camp, are running Windows 10 on their Apple machine -- are encountering a problem upgrading to Windows 10 May 2019 Update (version 1903).

A compatibility issue with the Mac HAL Driver (machaldriver.sys) is blocking the installation. The problem remains more than two months after the May 2019 Update was released, and Microsoft is still working away on a solution.
