There have been many RAM kits being touted as the world's fastest lately. It almost feels like an "arms race" where memory-makers are looking to outdo each other. For instance, both G.SKILL and Corsair recently claimed to have the fastest 32GB DDR4 SO-DIMM kit in the world. While both kits shared the same clock speed, the former beat the latter thanks to lower CAS latency.

Today, G.SKILL continues to brag about being the world's fastest, but this time, it is regarding its all-new 64GB DDR4 SO-DIMM kit. The 4x16GB kit runs at an impressive 3,466MHz with CL17-17-17-37 timings using 1.35V. Like the aforementioned 32GB SO-DIMM kit, these sticks are not designed for typical all-in-one computers or laptops, but instead, some desktops using the Intel X299 chipset.

Researchers from security firm GuardSquare have discovered an Android vulnerability that allows for app code to be edited without affecting the apps' signature. Dubbed Janus, the vulnerability has massive potential for malicious use, and affects Android 5.0 onwards.

The security hole would allow an attacker to tweak an entirely legitimate app to behave maliciously without triggering any security alerts. Although vulnerability CVE-2017-13156 has been patched in December's Android update, very few people will have access to this security fix.

Google is introducing changes to its Safe Browsing policies, requiring Android apps to display their own privacy warning if they collect users' personal data. The company says that if app developers refuse to comply, Google will display a warning of its own.

Developers have been given 60 days to comply with what is described as an expansion of Google's existing Unwanted Software Policy. Interestingly, it does not matter whether apps are featured in Google Play or they come via other marketplaces.

It is near impossible to avoid ads these days, but Google has just introduced a new policy that makes at least one area of your smartphone a safe haven.

The new policy means that most apps will no longer be permitted to display ads on the lockscreen. But while this is something that will please Android users, it's not something that the company has really trumpeted.

When consumers buy RAM for their computers, they often look at the rated speed. That is a smart thing to do, although it is only part of the picture. Actually, CAS latency timings are just as important, if not sometimes more so. You see, it is sometimes possible to get better performance out of slower RAM with a lower CAS rating. In other words, throwing money at MHz and ignoring CAS is a big mistake. Here is a great video to learn more about RAM timings.

Today, G.SKILL announces a 32GB CL17 Trident Z RGB DDR4-4266MHz memory kit, which the company claims is the only RAM at that speed with a CAS latency of 17. In addition, there are CL17 Trident Z RGB kits at 4000MHz and 4133MHz too. To prove stability, G.SKILL has successfully tested the kits using an impressive machine -- an Intel Core i7-8700K CPU and ASUS ROG MAXIMUS X HERO motherboard running Windows 10. The memory easily ran at both claimed speeds and latency without errors using Intel XMP 2.0.

Google is launching a crackdown on apps that misuse Accessibility Services, threatening to remove them from the Play Store. The API was created specifically to help users with various disabilities, but developers have latched onto it as a way of increasing the functionality of their apps.

The likes of Tasker, LastPass and Universal Copy are among the titles that make use of the Accessibility Services API, and they have been warned to either explain why they are using the API, stop using the API, or unpublish their app.

It may be more than a week until Black Friday, but the big-name companies are already releasing details of the money-saving deals that will be available. Microsoft is one such company, and today it has revealed price cuts for Surface devices, the Xbox One S, Windows Mixed Reality headsets, and more.

As well as offering savings of $329 off the Surface Pro i5 256GB, Microsoft also shares information about savings available from its partners -- including up to $300 off Windows 10 laptops.

For many home computer users, a five or even 10-year-old PC can be powerful enough for their needs. For some other people -- gamers and enthusiasts, primarily -- a computer can never be quick enough. These consumers will spend massive amounts of money for the latest and greatest hardware to achieve the fastest speeds.

If you like having the fastest hardware on your block -- whether you actually need it or just for bragging rights -- Corsair has a new memory kit that will tickle your fancy. The VENGEANCE LPX CMK32GX4M4K4333C19 kit runs at an insane 4,333MHz. This is the world's fastest RAM using a 4x8GB configuration, and it narrowly beats G.SKILL with its similar kit running at 4,2666MHz.

DisplayMate -- the display calibration and benchmarking firm -- has put the iPhone X through its paces and has come to the conclusion that it has the best smartphone display ever. This is an accolade that DisplayMate handed to the Samsung Galaxy S8 back in April, and with the iPhone X display having been supplied by Samsung, the new award is perhaps not a surprise.

While there have been some minor concerns about Apple's switch to an OLED panel, the move has definitely paid off. Apple is praised for the careful calibration it has put into the iPhone X's screen, causing DisplayMate to say: "the iPhone X is the most innovative and high performance smartphone display that we have ever tested."

Broadcom could be on the verge of carrying out the biggest technology acquisition in history. The chipmaker is said to be planning a $100 billion bid for smartphone chip supplier Qualcomm. It is possible that the bid could be even higher.

While the deal has not been officially announced, people familiar with the matter say the offer could be just days away. If Broadcom does go ahead with the purchase of Qualcomm, it would create a $200 billion company.

As a computer user in 2017, privacy is always on my mind -- as it should be. I suppose I have always cared about securing my information and data, but in recent years, we have learned so many troubling things about government hackers -- including the USA -- that it seems more important than ever. Patriot Edward Snowden really shone a light on the unfortunate state of privacy, or lack thereof, in modern days.

This is why I was very intrigued by the Purism line of laptops. These are computers that are designed with privacy in mind. The Librem 13 v2, which I have been testing, features two hardware kill-switches -- one will cut the webcam and microphone, while the other kills the Wi-Fi and Bluetooth radios. By cutting access on the hardware level, hackers cannot access these things when switched off. Instead of using a traditional bios system for booting, it even leverages Coreboot. It runs a Linux-based operating system called "Pure OS" which aims to be very secure and private. Unfortunately, the OS ends up being a little too secure, and the weak link of the overall package. But does that really matter?

When we reviewed the Maze Blade back in June, we were flabbergasted by the sheer amount of quality components that the Chinese vendor, Maze, managed to cram in this smartphone.

The Maze Alpha is the bigger brother of the Blade and has an even higher specification without adding much to the price.

When you pay big bucks for a smartphone you expect it to be flawless. That's why people make a big deal out the problems they find on a flagship device. Things are no different with Google's new Pixel 2 XL, which exhibits some serious issues.

The problems stem from its display which, put simply, is not of the highest quality. Users have reported color shifting when looking at the screen from an angle, poor color reproduction and, most-recently, burn-in. That last bit is especially worrying because the Pixel 2 XL has only been around for a couple of weeks.

I have mixed feelings about the Essential Phone. On one hand, it is a bold attempt at creating a high-end smartphone to go up against the iPhone and the Galaxy S. On the other hand, it is difficult to make a case for it, if you ignore the fact that its parent company was founded by the creator of Android.

When you ask a lot of money for a smartphone these days you have to offer more than the device itself. Things like in-store availability and easy access to support are just as important as the hardware. That's why people buy a ton of iPhones and Galaxy S devices: because Apple and Samsung get these things right. Essential is simply not there yet.
