Unlike most other modern computing devices, Raspberry Pis have no internal storage, relying instead on removable microSD cards as their primary boot drives. While it’s true that you can boot a Raspberry Pi 4 off of an USB SSD or Flash Drive, most of the time, it’s easier, more affordable and an overall better idea to stick with a microSD card.

But which microSD card should you buy for your Raspberry Pi? To help find the answer, we tested ten different 32GB cards on a Raspberry Pi 4, a Raspberry Pi 3 B+ and a Raspberry Pi Zero W to see which offers the best performance for the money.

We chose the 32GB capacity because it offers more than enough room for most use cases while not being appreciably more expensive than 16 or 8GB cards. Raspberry Pi OS can run on a card that’s as small as 8GB (see how to set up a Raspberry Pi), but that leaves you very little extra space. With every update and release slowly using more and more of your card, 8GB will soon become too small for a typical setup. Even if you are running a game emulation system with lots of ROMs, you are unlikely to exceed 32GB (though some have).

The Best microSD Cards for Raspberry Pi

1. Silicon Power 3D NAND

Best Overall

Capacity: 32GB | UHS Speed Class: 1 | Speed Class: 10

Strongest Raspberry Pi 4 performance

Good performance overall

Low price

White surface for labeling

Slow boot times

Lesser-known brand

We’re honestly shocked that the best performing Raspberry Pi microSD card in our roundup is also the cheapest one and comes from a lesser-known brand. It’s also rated UHS Speed 1 rather than 3, although these ratings are largely meaningless (at least for Pi owners). In fact, we were so surprised at this card’s performance that we tested a second unit to make sure the first one wasn’t a fluke.

For a price of just $6.99 (£5.99) at publishing time, the Silicon Power 3D NAND achieved the highest speeds on the Raspberry Pi 4 in almost all the IOzone tests, especially with 4K random writes. It also, by a hair, loaded all of our apps fastest on the Pi 4, though its boot time was second slowest. The Silicon Power NAND 3D card also performed well on Raspberry Pi 3 B+ and Pi Zero W, though it didn’t lead in as many categories.

In addition to its performance, the card has one huge advantage over most of its competitors: the ability to physically write on it. Because the surface is partially white, you can scribble on it with a Sharpie marker. That helps immensely when you have multiple cards in a drawer and don’t know which is which.

2. SanDisk Extreme Pro

Great Speeds, Best for Pi 3

Capacity: 32GB | UHS Speed Class: 3 | Video Speed Class: V30 | Application Speed Class: A1 | Speed Class: Class 10

All-around great performance

Fastest card for Raspberry Pi 3 B+

Relatively expensive

SanDisk claims that the Extreme Pro can read at up to 100 MBps and write at up to 90 MBps and has labeled it with a UHS rating of 3, a Video Speed Rating of 30 and an Application Speed rating of A1. As we note below, these ratings aren’t very useful, but nonetheless, this card is indeed one of the fastest around.

On the Raspberry Pi 3 B+, the SanDisk Extreme Pro finished first in six out of eight IOzone tests, including random 4K reads and writes. On Raspberry Pi 4, the card was within a few tenths of a second of the fastest application open times on the Raspberry Pi 4 and it was 0.5 MBps or less behind the leader in the all-important 4K random read and write speeds on IOzone. It also had the fastest sequential write speed on the Raspberry Pi Diagnostic test.

SanDisk backs the Extreme Pro with a limited lifetime warranty and claims that it is waterproof, shockproof and X-ray-proof.

3. Kingston Canvas React

Fastest booting Raspberry Pi microSD

Capacity: 32GB | UHS Speed Class: 3 | Video Speed Class: V30 | Application Speed Class: A1 | Speed Class: Class 10

Speedy boot times

Strong application opens

Great 4K reads and writes on Pi Zero

Mediocre 4K reads and writes on Pi 4

The Kingston Canvas React was in the upper performance tier on nearly all of our Raspberry Pi microSD card tests and it stood out by being the fastest booter on both the Raspberry Pi 4 and Raspberry Pi 3 B+. It also provided application open times that were consistently among the best.

The card’s only real downside is modest (but not terrible) 4K reads and writes on the Raspberry Pi 4. On the Raspberry Pi 3 and Zero, which have a slower microSD card reader, its 4K scores were better relative to the competition.

Kingston backs the Canvas React with a limited lifetime warranty, but it does not claim that the card is waterproof or shockproof in its market materials.

4. Samsung Pro Endurance

Long-lasting Raspberry Pi microSD Card

Capacity: 32GB | UHS Speed Class: 3

Claims long lifespan

Strong app open, boot times

Leading 4K random reads

None

While it doesn’t win every test, the Samsung Pro Endurance is a great all-around Raspberry Pi microSD card that promises up to 25 times greater longevity than a typical card. While we can’t prove or disprove this claim, we do know that Samsung has an excellent reputation in the industry and backs the card with a limited lifetime warranty. The company also says that the card is waterproof, temperature-proof and X-ray-proof.

The Samsung Pro Endurance comes close to the leaders on application open times and boot times while achieving fast transfer speeds on every test on every Pi model. On the Raspberry Pi 4, it achieved the fastest 4K random reads on IOzone and the speediest sequential transfer rate in the Raspberry Pi Diagnostics tool. Though it is labeled as UHS 1 speed, it hangs with or outpaces cards that are labeled UHS 3. At $10.99 at publish time, it’s not the cheapest card, but also not the most expensive.

5. Samsung Evo Plus

Good Raspberry Pi microSD performance for the price

Capacity: 32GB | UHS Speed Class: 3

Good price

Fast application open and boot times

None

Selling for a modest $8.51 (£7.29) at publication time, the Samsung Evo Plus offers solid performance from a highly-trusted brand at a very reasonable price. Samsung backs the Evo Plus with a 10 year warranty and claims that the card can survive X-rays, magnetic radiation and even 72 hours in seawater. Most of us probably aren’t worried about submerging a card in water, but it’s nice to know that if you waterproof your Raspberry Pi, the card will be fine too.

In our tests on the Raspberry Pi 4, the Samsung Evo Plus offered consistently strong application opens, coming within 0.2 to 0.3 seconds of the leader. It also booted in a speedy 24.7 seconds, only 0.7 seconds slower than the Kingston Canvas React. The card had solid transfer rates in IOzone, though its 4K random writes were a little disappointing (rates were much higher in the Raspberry Pi Diagnostic test). On the Raspberry Pi 3 B+, the Evo Plus got really good application open times and slightly better 4K writes.

Other Raspberry Pi microSD Cards We Tested

Not every product deserves to be listed as one of the best Raspberry Pi microSD cards. Here are some other cards we tested and our brief take on each.

SanDisk Extreme: This card really was not bad, offering solid all-around performance for, at press time, a little more than $10 or £10.

PNY Performance Turbo: The most expensive card we tested at $14.90 (UK price N/A), this card did not live up to its name or its price tag. The Raspberry Pi Diagnostic tool gave the Performance Turbo a failing grade, thanks to an awful 4K random write speed of 0.8 MBps. Its sequential numbers were also subpar.

Lexar 633x: The second least expensive card we tested, the Lexar 633x isn’t all bad. Its app open and boot times were good, but its 4K random write speed and its sequential write speed were poor enough for it to flunk the Raspberry Pi Diagnostic test.

Silicon Power Elite: This card costs a few dollars more than the Silicon Power 3D NAND and yet it performs so much worse. It was the slowest card to boot by far, taking more than twice as long as the fastest booting card on both the Pi 4 and Pi 3 B+, the Kingston Canvas React. It had the slowest app open times and also failed the Raspberry Pi Diagnostic Test.

Fatty Dove: You wouldn’t expect much of a no-name brand like Fatty Dove so you won’t be disappointed. This card was rated UHS 3, proving how meaningless these speed numbers are. It failed the Raspberry Pi Diagnostic test, thanks to really poor 4K random writes and overall sequential writes.

MicroSD Speed Ratings and Types: What Do They Mean?

When you’re shopping for a microSD card, whether it’s for Raspberry Pi, a phone, a camera or a Nintendo Switch, you’ll see as many as four different types of speed ratings listed, the first three of which measure minimum sequential write speed in MBps. The SD Association provides a detailed explanation by to keep it simple, here’s a brief list:

Speed Class: The oldest class system appears with a circle around the number. The highest class, class 10, is a mere 10 MBps so any new card will meet this standard.

UHS Speed Class: This is the most common spec and appears as either a 1 or a 3 inside of a U symbol. The 1 promises 10 MBps and the 3 offers 30 MBps. However, in practice, we’ve tested cards rated as UHS 1 that were just as fast as 3s.

Video Speed Class: This is shown as a V with a number after it and is commonly shown as V30 (30 MBps), V60 (60 MBps) or V90 (90 MBps).

Application Speed Class: This is a newish metric that measures IOPS rather than sequential throughput. Cards can be rated either A1 (1,500 IOPS random read / 500 IOPS random write) or A2 (4,000 IOPS random read / 2,000 IOPS random write). Few of the cards we tested were rated for A1 (and none for A2) as 32GB cards don’t tend to have this classification. However, several users in the Pi community report that the A2 cards make no difference in Pi performance. Jeff Greeling has a comprehensive article comparing A2 and A1 microSD card performance on Raspberry Pi where he finds zero benefit.

Almost all cards are marked with the UHS rating or 1 or 3, fewer have the Video Speed and only a few high-end cards are marked with the Application Speed. In addition to labeling their cards with some of these classes, vendors will offer their own estimates that are much more generous. For example, Samsung claims that its Pro Endurance card can get up to 100 MBps reads and 30 MBps writes, even though it is only labeled as UHS class 1 (10 Mbps). In practice, these classes meant nothing, because cards with UHS class 1 often outperformed those with class 3.

You’ll also see that some cards are listed as microSDHC while others are specked as microSDXC. These standards mean nothing for performance and only tell you something about the capacity that you already know from the number of GB. microSDHC (high capacity) cards are those that go up to 32GB and microSDXC cards support higher capacities (but could also be 32GB). Either type works fine in a Raspberry Pi.

How We Tested Raspberry Pi microSD Cards

We used a combination of synthetic and timed tests to measure microSD card performance on Raspberry Pi. Because it has the highest possible transfer speeds, we ran the full suite of tests on the Raspberry Pi 4, including FIO (Flexible Input / Output tester), which usually took more than five hours to complete. On the Pi 3 B+, we ran just IOZone and the application and boot time tests and, on the Pi Zero W, which is slow to open every app, we used IOZone alone.

IOZone Results on Raspberry Pi microSD Cards

IOzone is a popular Linux storage benchmark that measures read and write speeds. We owe a huge hat tip to Jeff Geerling whose excellent article on microSD card benchmarks inspired us to use IOzone in our testing. We configured it to test both random and sequential reads of 4K and 1,024K blocks with a total file size of 100MB. We also enabled the direct I/O option that bypasses the operating system’s cache so we’re getting a better idea of the card’s performance on its own.

When we tested on the Raspberry Pi 4, the Silicon Power 3D NAND card, which coincidentally is listed as UHS Speed 1, comes out on top in the all-important 4K random write, 4K sequential write, 4K sequential read, 1,024K random read and 1,024K sequential read tests. The SanDisk Extreme Pro, Samsung Pro Endurance and Kingston Canvas React all put in strong showings as well. The Silicon Power Elite, while more expensive than the company’s 3D NAND did very poorly as did the Lexar 633x, the PNY Performance Turbo and the Fatty Dove 32GB card.

The SanDisk Extreme Pro dominated the IOzone tests on the Raspberry Pi 3 B+, placing first in every category but 1,024K random writes and 4K sequential writes. The same cards that did poorly on the Raspberry Pi 4 were equally awful on the Pi 3 B+.

IOZone performance on the Raspberry Pi Zero W was more of a mixed bag, with a more even spread of top performers in different rounds. However, the SanDisk Extreme Pro won the most rounds.

Application Open Times of Raspberry Pi microSD Cards

One of the most visible manifestations of Raspberry Pi microSD card performance is how quickly your favorite apps load. To measure, we timed four popular pieces of software: Chromium Browser, GIMP, LibreOffice Calc and Scratch Desktop 3. For better or worse, on both the Raspberry Pi 4 and 3 B+, there was very little difference between the best and worst open times, with differences of tenths of a second separating the competitors.

Despite the minor differences between cards, on the Pi 4, the Silicon Power 3D NAND had the fastest times on every app while different cards came out on top for each application on the Pi 3 B+.

Boot Times on Raspberry Pi microSD Cards

Eight out of the ten cards booted Raspberry Pi 4 in between 24 and 26 seconds, with the Kingston Canvas React taking the crown at 24 seconds. Though the Silicon Power 3D NAND card did so well on application opens, it had a significantly slower boot time. And, at 49.3 seconds, the Silicon Power Elite card was a disaster.

The boot times on the Raspberry Pi 3 B+ told a similar story. All of the non-Silicon Power cards were within two seconds of each other, with the Kingston Canvas React again taking the booting crown. The Silicon Power 3D NAND card wasn’t awful at 28.9 seconds, but the Elite took a leisurely 50 seconds.

Raspberry Pi Diagnostics SD Card Speed Test

The Raspberry Pi Foundation has its own speed test, which measures 4K random reads and writes, along with sequential writes (of an undisclosed size). The test not only provides numbers, but also a pass or fail rating, based on the results.

(Image credit: Tom’s Hardware)

We tested all of our cards on the Raspberry Pi 4, using the Diagnostics test and four of them — the PNY Performance Turbo, Lexar 633x, Silicon Power Elite and Fatty Dove outright failed — due to horribly slow 4K random writes. While the numbers were sometimes higher than we saw for the same cards in IOzone, they told a similar story.

The fastest card for 4K random writes was the Silicon Power 3D NAND while the leader in 4K random reads was the Samsung Evo Plus and the sequential winner was the SanDisk Extreme Pro.

Bottom Line

The differences between the best cards are subtle enough that you may not be able to tell our top choice from one further down the list in every workload. However, our testing shows that clearly not every Raspberry Pi microSD card is the same and there are many poor performers you should avoid. And just because a card carries a particular speed rating, for example UHS 3, that doesn’t mean that it will be faster than another card that has a lower rating.

After arriving on the desktop, the dark mode is finally being tested also on the Facebook mobile application. This is how it will look like

by Nino Grasso published 02 November 2020 , at 15: 55 in the Telephony channel

Facebook

Facebook is finally testing a dark mode in its mobile app, and has started rolling out the feature to a handful of hand-picked clients. The news was officially confirmed on Jane Manchun Wong’s Twitter channel, who posted a video showing the new “dark” interface in action. The video was made in collaboration with the social media giant and lasts slightly longer than half a minute. Here it is.

The dark mode on Facebook will arrive on both iPhone and iPad, as well as Android devices. It is not clear with which criteria Facebook has chosen the clients on which to activate the mode, which has been loudly requested by several users over the last few months. Anyone who has received the functionality can enable it through a new option in the Settings menu, within the Settings & privacy . The user can force the activation of the dark mode always, keep the light mode, or enable it only when the system setting requires it.

The dark theme on Facebook for iOS and Android is coming

On iOS and some versions of Android, therefore, the user can synchronize the dark mode of Facebook with that of the operating system, then enable it – if provided for by the latter – only at night or in certain circumstances chosen by the user.

Facebook users have been waiting for a long time for the dark theme on mobile . In March the new UI was introduced on desktop, while on Messenger the option was made available even during 2019. The reasons for such a prolonged delay with regard to the main Facebook app are not clear, however, considering the volume of users and the heterogeneity of the content processed, it is understandable that the company wanted to approach it in the most precautionary way possible.

Chrome is supposed to validate certificates itself in the future and wants to create even more security for users. To this end, Google is working on a root store. So far, the browser relies on the respective operating system to verify HTTPS connections.

Don’t miss any news! With our daily newsletter you will receive all the news from heise online from the past 24 hours every morning.

The “Chrome Root Program” can be found in the Chromium projects. Information about the time of the change is not yet available. However, guidelines and requirements for certification authorities have already been described so that they can prepare a smooth transition.

Root stores verify the validity of certificates . When an encrypted HTTPS connection is established, a check is made as to whether the certificate of a site has been authenticated by a certificate contained in the root store. This is to rule out man-in-the-middle attacks.

Exception iOS So far, Chrome has used the root store of the operating system, ie the “Microsoft Trusted Root Program” for Windows and the “Apple Root” for MacOS Certificate Program “. The only exception should be iOS in the future, Chrome will not use its own root store there. Mozilla has also had its own root store for Firefox from the start. For administrators who maintain lists for companies, for example, the change means additional work.

A few months ago there were rumors that Huawei was planning to open its own factory to manufacture processors as part of the US sanctions. According to a report in the Financial Times, plans now appear to be concrete. The factory is to be built in cooperation with a partner company called Shanghai IC R&D, which will operate the factory. The interesting thing: In order not to offer the USA a target for sanctions, the factory should run completely independently of US companies and their technologies.

In the past, Huawei was repeatedly taken away from possible trading partners such as TSMC by US sanctions. Probably the best known and most devastating effect is still the ban on using the Android operating system. This makes smartphones of the brand that is actually popular in the West uninteresting for most users, as Google services such as the PlayStore or similar are no longer available To be available. Only recently they presented concrete plans to establish their own mobile operating system called Harmony OS.

The commissioning and production of the first chips should start this year. For the time being, however, only the rather outdated 45 – nm process can be used, a Production in the 20 – nm process should then be carried out by the end of next year consequences. It will be some time before Huawei can produce competitive SoCs for high-end smartphones and other mobile devices.

For comparison: Apple is already working with the chip manufacturer TSMC on a 2 nm manufacturing process. However, their own chips still offer new possibilities in the area of smart TVs and the Internet of Things. In the year 2022 the production of 20 – nm structure widths follow, together with the start of production for 5G technologies.

Although own production is owned by the Chinese group secures long-term prospects, it remains unclear how the company will survive the next few years. After all, with the de facto ban on the sale of usable mobile devices outside of China, the most important source of income breaks away. Huawei has not yet commented on the plans.

With the Novasom M9, Novasom Industries presents an alternative to the popular single-board platform Raspberry Pi. The new model supports not only fast M.2 memory, but also the connection of multiple displays. The board has a dimension of 105 mm x 56 mm.

The CPU forms an RK 3399, which with two Cortex-A 72 – and four Cortex-A 53 – cores and thus offers a comparatively high computing power. In addition, a 4 GB RAM is used. A full-size HDMI output and a DisplayPort output are available for connection to a monitor. The connection of popular displays from maker circles is also possible via MIPI. This also offers the option of connecting cameras.

The internal storage capacity is up to 128 GB. Compared to the competition, the Novasom M9 also offers an M.2 slot as a special feature, via which the corresponding SSDs can even be connected using the powerful NVMe protocol. A slot for the use of microSD cards is also installed, which can also be used to install an operating system. Ethernet port for connection to a network. WiFi is available for wireless connections 802. 11 a / b / g / n / ac ready. There is also a 2.5 mm audio connection. According to the manufacturer, there is also (charging) electronics on board, which should enable an uninterruptible power supply. Exact technical specifications can be found here.

At the moment there is no information on price or release date. The models of the M9 series are largely compatible with the Raspberry Pi via Raspmood.

The Raspberry Pi Foundation unveiled the Raspberry Pi 400, a system within a keyboard that resembles systems like the Atari. The product is proposed as a low-cost PC for children, schools and simple hobbyists.

by Manolo De Agostini published 02 November 2020 , at 12: in the Systems channel

Raspberry

The Raspberry Pi Foundation unveiled the Raspberry Pi 400 , a computer integrated in a compact keyboard (286 x 122 x 23 mm): its price in the version with Italian layout is 74, 90 EUR. It is a ready-to-use product (or almost), just connect a couple of cables to start using a system that recalls the systems of the years 80 like the Atari. Its purpose is clearly to offer itself as a low-cost PC for children, schools and simple hobbyists .

Totally fanless, the computer keyboard is technically similar to the Raspberry Pi 4 , in fact it has a Broadcom BCM 2711 quad-core (ARM Cortex-A SoC to 64 bit) at 1.8 GHz, 4 GB of RAM and Wi-Fi ac connectivity, Bluetooth 5.0, Bluetooth LE and Gigabit Ethernet.

Also present two micro-HDMI ports, which means you can connect two 4K screens , in addition to two USB 3.0, one USB 2.0 and one USB C for power. Obviously there is no shortage of a slot microSD (for the operating system and save your data) and the GPIO connector .

Beyond to the Raspberry Pi only 400, the foundation allows you to purchase a kit consisting of the product, a mouse, a power supply, a micro-HDMI to HDMI cable and a preformatted microSD card, as well as a guide for novices , to 106 EUR.

Advantages and disadvantages of free games on Android

Thanks to our phone we can take advantage of the dead times to read , check the internet or the mail and play some games, if we have downtime on public transport or on breaks we can play a game that we have at hand and that is quick games, in this guide we are going to teach you the best games for Android , we have a guide dedicated to the best free games for iPhone here.

Android is a operating system with a much higher share than the rest in the market, we can take advantage of this device as a portable console in a casual way , in situations where we have time we can entertain ourselves with any of the games that we have installed. In the Play Store there are games for everyone , free and paid games, to play short games or adventure games with a much longer duration.

Generally these type games casual are of the Free to Play type, this means that you can download them for free to play , but that have in-app purchases or advertising to support the development of this game. Within the free games there are the type pay to win , which you will need to make some disbursement if you want to evolve or advance in the game.

Free games with advertising or micropayments

The main advantages of this type of free to play games is, as the name suggests, that they are free , also are casual and do not require much attention or dedication to continue, simply the skill that you acquire throughout the game. For example, the famous Candy Crush we will have to put together 3 candies of the same color to pass the screen, as you advance they get more complicated levels with different goals to achieve.

On the contrary, these types of games also have their disadvantages , if We continue with the example of Candy Crash and if you already have a little experience, the levels begin to be more complicated and we have limited lives to try to pass the level, when lives are over we will have to wait a while for them to recharge, or we have the option of paying to recharge lives in addition to being able to buy power-ups and objects to make us more easy to win the game.

Pay to continue in the game

It is possible that these types of games offer you these objects and advantages for free initially or during the l play to encourage purchase. In addition, on some occasions we will be unable to advance further in the game or evolve our character , in this case we will have to make a purchase to obtain that necessary power-up and continue playing, These are called Pay to Win , in which if you do not make this purchase, you will be stuck.

An example of this type of game is Clash Royale , where you will have to pay if you want to level up your cards quickly , you can also pay for open the chests ahead of time which will give you a slight advantage compared to those who have not paid anything and are at the same trophy level as you.

Whatever the type of game, paying or not is your choice, you can leave the game if you see that at any time it is necessary to make a payment to continue or advance, there are thousands of games in the play store but we are going to leave you os 12 best games for Android.

The best games for Android

In this section we are going to classify the 12 best games for Android from the tenth to the first , there are varied themes and all free , although if you wish you can pay for extra items.

12 – Asked

This is the typical quiz game that has several game modes , in the classic one, which is the most used, you will have to do turn the roulette wheel and correctly answer the question of the theme that has come out to continue with the turn and win your opponent, answering more questions than him.

The game has integrated advertising with extra rewards when watching sponsored videos or a store where you can buy items for the pet, buy lives, correct answers or gems, where you will clearly acquire an advantage over your partner, we could say that this game is of type Pay to Win .

9 – Gardenscapes

This time you will incarnate in the skin of a character who decides to completely remodel his garden , for this we will need stars that we will gain as we go solving the puzzles that presents, with a theme similar to Candy Crash, but with the addition of the decoration of the huge garden, we will have to form rows of colors to get the increasingly complicated objectives that he proposes to us to win the star and carry out the next mission.

With Gardenscape we will also have a limit of lives to consume , after these we will have to wait half an hour for each life that is recharged with a maximum of 5, although It is possible to buy a pack of enhancers with infinite lives for a while for a few euros in their own store, in this game they offer us these enhancers as a reward, but for free.

8 – Candy Crush

This is the typical game for fast and casual games , in this way we can play practically anywhere and with very little time spent, the puzzle game consists of putting together candies of the same color and complete the missions that are indicated, more complicated as we advance levels.

This game has limited lives , and when we lose we will have to wait Take some time to recharge lives, although we can also share our progress with friends on social networks to get rewards or buy power-up packs and lives for a few euros .

7 – Sonic the Hedgedog

A classic of the platforms of Sega’s hand, the hedgehog has to go through the screen until it reaches the end without being eliminated , you will have to catch rings To obtain greater rewards, at the end of each phase there is a final boss that you will have to defeat. Each 100 rings you will get one life and each 98 the possibility at the end of the phase to play the dream of Sonic to get the gem , get them all.

This game is free if we play it with ads that will appear at the end of the levels, on pause or before starting to play, but not during the game. This would be another example of a game Free to play with advertising .

6 – Pokemon Go

In this Niantic game we will have to move through the streets of our city to find and capture Pokemon , you will travel through a real map where they can appear anywhere, there are poke stops where you can get pokeballs and objects to attract and catch more Pokemon , you will have to catch them all taking into account the places where they can appear and the time of year, for example, water-type Pokemon can be seen more by sources, rivers or the sea.

You might take a good walk and find quite a few Pokemon to catch, pokeballs are a limited resource and you can’t visit a poke stop twice in a row to get more pokeballs, you will have to wait a while, or You can buy Pokemon coins with money and exchange them for these pokeballs or other available objects. It is not an advantage over others, but it does facilitate the capture of Pokemon.

5 – Brawls Stars

In this game, from the same company as Clash Royale, we will form teams of 3 players where the objective of the game is the team that has the greatest number of gems. at the end of the time they will have won the game, you will have to defeat the enemy to remove their gems or take them from the center of the screen before them, at the end and win the game you will get coins to improve your character .

In this game also we can get these coins by paying in the store included in the game, we can buy coins to get these improvements without having to play and win games, leveling up much faster.

4 – PUBG Mobile

As in e l PC game, but adapted to the screen of a mobile phone, we will have to fight against the 100 remaining that fall on the map from the plane to survive the last one, we will have to explore all the corners to go making us with equipment and weapons with which to defeat the enemies while keeping an eye on the circle that is closing in order not to be left out of the field of play.

In PUBG Mobile we can buy the season pass as usual in these games , as we gain experience and we finish games we can go unlocking objects aesthetic for our character. If we have the season pass these objects will be less common and more exclusive.

3 – COD Mobile

The Call Of Duty Mobile is one of these games that are not fast games , here we will have to have something else of time, when you reach level 4 after playing some games of 5 against 5, you can enter in the Battle Royale mode , like the Modern Warfare that we tell you here. You will have to defeat 100 enemies to be the last and win the game to acquire points that will make you increase the level and obtain rewards.

We can obtain weapon and character upgrades by exchanging the coins that will give us the end the game, also you can buy a premium season pass to get better items every time we win a game and level up.

2 – Fortnite

A few weeks ago, Intel announced 11 generation Tiger Lake processors for laptops based on the Willow Cove architecture and lithography 10 nm SuperFin. With the new cores, integrated Intel Iris Xe Graphics also entered the game, making it the first product to take advantage of the rebuilt Xe architecture. For the manufacturer, it is certainly an apple of the eye, especially since the plans for this architecture are very extensive and apply not only to laptops, but also to desktops, servers and even supercomputers. In this way, Intel wants to enter the game as the third major manufacturer of dedicated graphics cards after years of absence in this market. The first combat test, however, will be the more modest Intel Iris Xe MAX Graphics card, which is to fight NVIDIA GeForce MX systems in notebooks. As the first editorial office in Poland and one of the few in the world, we invite you to test a laptop with a dedicated Iris Xe MAX Graphics card.

Author: Damian Marusiak

Acer Swift 3X will be based on processors 11 Intel Tiger Lake-U generation. We will get a choice of 4-core and 8-thread Intel Core i5 units – 1135 G7 and Intel Core i7 – 1165 G7. An even more interesting element of the design will be the presence of a dedicated graphics card. Not NVIDIA cards and not AMD. I am talking about the first graphics card from Intel in the form of the Iris Xe MAX Graphics chip in twenty years. These are the first steps of the manufacturer to create an attractive GPU line that will be able to compete with both AMD and NVIDIA. However, the full potential of the Xe architecture will not be seen until next year, when much more advanced designs based on the Xe-HP architecture with hardware Ray Tracing acceleration will come out. The Acer Swift 3X laptop has the first card, which until recently was known as Intel DG1 – Discrete Graphics 1.

As the only editorial office in Poland, we invite you to Testing the Acer Swift 3X laptop with a dedicated Intel Iris Xe MAX Graphics card. Will it be able to break the hegemony of NVIDIA?

“src =” https://www.purepc.pl/image/artykul/2020 / 10 / 31 _ test_acer_swift_3x_premiera_karty_intel_iris_xe_max_graphics_0.jpg “>

Perhaps to the surprise of many people, the dedicated Intel Iris Xe MAX Graphics card in terms of specifications will be very similar to the integrated Iris Xe Graphics chip. Like iGPU, it has 96 Execution units (EU), which translates into 768 The two differences are the amount of RAM allocated and the core clock. Intel Iris Xe MAX Graphics are available 4 GB of LPDDR4x RAM clocked at 4267 MHz, which translates into bandwidth order 68 GB / sec. The core clock is also noticeably higher, reaching a maximum of 1650 MHz. Due to the fact that it is a dedicated card, it is not associated with the processor with a common energy limit. This means that, for example, in games, the processor receives the entire energy budget and can work with a higher clock, and the Iris Xe MAX Graphics card has its own budget and thus, regardless of the processor, it can achieve a higher clock speed in the Boost mode.

Acer Swift 3X setup:

Intel Core i7 processor – 1165 G7 (2.8 GHz – 4.7 GHz)
16 GB of RAM LPDDR4X 4266 MHz / Dual Channel
Integrated Intel Iris Xe Graphics
Intel Iris Xe MAX Graphics / 4 GB LPDDR4x
Matrix 14, 0 “/ Matte IPS / Resolution 1920 x 1080 pixels
SSD: 1 TB / Micron 2210 / PCIe 3.0 x4 NVMe Interface
Microsoft Windows operating system 10 Home 2004

Another feature of the Acer Swift 3X laptop is undoubtedly the use of Intel Tiger Lake processors (11 generation of Intel Core chips). There was a lot of talk about processors long before their final debut (September 2). First of all, they use the redesigned Willow Cove architecture, based on last year’s Sunny Cove. Mainly the cache memory subsystem has been changed, increasing the number of L1 cache, L2 cache and L3 cache. Also used was a noticeably improved 10 nm technological process, named 10 nm SuperFin. The name is related primarily to the use of new SuperFin transistors, which are to enable work with a higher clock at the same time lower voltages. The tested version of Acer has an Intel Core i7 unit – 1135 G7, equipped with 4 cores and 8 threads. The base clock of the processor is 2.8 GHz with the possibility of increasing in Turbo Boost 2.0 mode to a maximum of 4.7 GHz. Intel Core i7 – 1165 The G7 has a default TDP of 28 W. The processor not only supports the Thunderbolt 4 platform, but is also the first to introduce PCIe 4.0 to notebooks. Also supports DDR4 3200 MHz, LPDDR4X 4267 MHz and LPDDR5 5400 MHz – the latter will not appear in laptops, however, until next year.

The Windows kernel cryptography driver (/cng.sys/) provides a / Device CNG / device for user mode programs and supports a large number of IOCTLs calls with non-trivial input structures. This driver represents a locally accessible attack surface that can be exploited to escalate privileges. Security researchers therefore focus on this driver in order to find vulnerabilities.

Don’t miss any news! With our daily newsletter you will receive all the news from heise online every morning from the past 24 hours.

At the 22. October 2020 Mateusz Jurczyk and Sergei Glazunov from Google’s Project Zero discovered a 0-day vulnerability (CVE – 2020 – 17087) in the Windows kernel. In a proof-of-concept under Windows 10 1903 (64 Bit) can provoke an integer overflow and crash of the operating system. The vulnerability offers the possibility of a privilege escalation, so that malware could break out of a sandbox. This applies to the sandboxes used in browsers as well as in some Windows security functions as well as in virus scanners to isolate processes.

Is used via an exploit chain The security researchers at Project Zero have decided to fix the 0-day vulnerability, for which Microsoft does not yet have a patch, within a period of 7 Days to publish. The background: The team has evidence that this 0-day vulnerability in conjunction with a recently discovered 0-day vulnerability in the FreeType program library used by the Chromium browser (Google Chrome, Microsoft Edge) is already included via an exploit chain Attack is exploited.

The Chrome 0-Day Exploit (CVE – 2020 – 15999) has meanwhile been updated by Google Chrome updates 86. 0. 4240. 111 closed. Also with the Microsoft Edge browser the version 86. 0. 622. 51 the active exploited vulnerability in the FreeType program library eliminated. Windows users should make sure that Chromium-based browsers used (e.g. Vivaldi) are patched for this vulnerability.

Windows 7 to Windows 10 affected The security researchers from Project Zero assume that the vulnerability CVE – 2020 – 17087 in the Windows kernel cryptography driver (/cng.sys/) has existed since Windows 7. That means all Windows versions, from Windows 7 to the current Windows 10 20 H2, including the server counterparts affected. In Google Project Zero, it is assumed that the vulnerability reported by Microsoft will be released by the next patch day on 10. November 2020 will be closed.

One of the worst jobs in the world right now is being a greeter at a retail store who has to tell people to put on their face masks. Instead of making a human check for mask compliance, we can create a Raspberry Pi-powered mask detector that uses image recognition. Then unruly patrons can yell at a Raspberry Pi screen instead.

In this article, we’ll show you how to set up a Raspberry Pi Face Mask Detection System and sound a buzzer when someone is not wearing their face mask. This project was inspired by a video of a mall in Asia where an entry gate could only be activated by a user wearing a face mask.

(Image credit: Tom’s Hardware)

How does the Raspberry Pi Face Mask Detector project work?

When a user approaches your webcam, the Python code utilizing TensorFlow, OpenCV, and imutils packages will detect if a user is wearing a face mask or not. Users not wearing a face mask will be designated with a red box around their face, and users wearing a face mask will see a green box around their face with the text, “Thank you. Mask On.” Users not wearing a face mask will see a red box around their face with, “No Face Mask Detected.”

How long does the Raspberry Pi mask detector project take?

Starting with a fresh install of the Raspberry Pi OS, to complete all elements of this project will take at least 5 hours. If you completed our previous post on Raspberry Pi Facial Recognition, you can subtract 1.5 hours for the install of OpenCV. Even better, we’ve included a pre-trained model for you to jump directly to a working Pi mask detection system.

ICYMI – Facial Recognition with Raspberry Pi: We recently posted a facial recognition tutorial where we used machine learning to train our Raspberry Pi to recognize specific faces. This tutorial uses many of the same principles of machine learning and AI, but today we are adding TensorFlow to identify an object, specifically a face mask. We recently featured another Raspberry Pi Tensorflow project that determined if a cat was carrying prey to its owner’s door.

What You’ll Need for Raspberry Pi Face Mask Detection

Raspberry Pi 4 (Raspberry Pi Zero is not recommended for this project, and the Raspberry Pi 3 ran very slowly.)
16GB (or larger) microSD card (see best Raspberry Pi microSD cards) with a fresh install of Raspberry Pi OS
Power supply/Keyboard/Mouse/Monitor/HDMI Cable (for your Raspberry Pi)
USB Webcam or Raspberry Pi Camera
Optional: 7-inch Raspberry Pi touchscreen
Optional: Stand for Pi Touchscreen

The majority of this tutorial is based on terminal commands. If you are not familiar with terminal commands on your Raspberry Pi, we highly recommend reviewing 25+ Linux Commands Raspberry Pi Users Need to Know first.

Part 1: Install Dependencies for Raspberry Pi Face Mask Detection

In this step, we will install OpenCV, imutils, and Tensorflow.

OpenCV is an open source software library for processing real-time image and video with machine learning capabilities.
Imutils is a series of convenience functions to expedite OpenCV computing on the Raspberry Pi.
Tensorflow is an open source machine learning platform.

1. Install fresh copy of the Raspberry Pi Operating System on your 16GB or larger microSD card. Check out our article on how to set up a Raspberry Pi for the first time or how to do a headless Raspberry Pi install. We tried this project by running ‘sudo apt-get update && sudo apt-get upgrade’ and we failed to build / install OpenCV.

2. Plug in your webcam into one of the USB ports of your Raspberry Pi. If you are using a Raspberry Pi camera instead of a webcam, use your ribbon cable to connect it to your Pi. Boot your Raspberry Pi.

There will be an optional step to add LEDs and a buzzer in the last step.

3. If you are using a Pi camera instead of a webcam, enable Camera from your Raspberry Pi configuration. Press OK and reboot your Pi.

(Image credit: Tom’s Hardware)

4. Open a Terminal. You can do that by pressing CTRL + T.

5. Install OpenCV. This step takes about 2 hours. Please see Part 1 of our Raspberry Pi Facial Recognition Tutorial for full instructions on installing OpenCV. Upon completion of installing OpenCV, your terminal should look something like this:

(Image credit: Tom’s Hardware)

6. Install TensorFlow. This step took about 5-10 minutes.

sudo pip3 install
https://github.com/lhelontra/tensorflow-on-arm/releases/download/v2.1.0/tensorflow-2.1.0-cp37-none-linux_armv7l.whl

7. Install imutils. This step took about 1 minute.

sudo pip3 install imutils

Part 2: Face Mask Detection (Short-Cut Method)

In this section, we will skip training the model and run a pre-made model to identify if you are wearing a face mask or not.

1. Open a new terminal on your Pi by pressing Ctrl-T.

2. Download the code from GitHub.

git clone https://github.com/carolinedunn/face_mask_detection

3. Run the pre-made model trained with over 1,000 images. In your terminal change directory (cd) into the directory you just cloned from GitHub.

cd face_mask_detection

4. Run the Python 3 code to open up your webcam and start the mask detection algorithm.

python3 detect_mask_webcam.py

If you are using a Pi Camera, enter python3 detect_mask_picam.py

After a few seconds, you should see your camera view pop-up window and see a green box indicating face mask presence.

(Image credit: Tom’s Hardware)

Or a red box indicating lack of face mask.

(Image credit: Tom’s Hardware)

You can try experimenting with various face masks, improper and proper wearing of your face mask (i.e. face mask hanging from your ear, or face mask below the nose).

Press ESC to stop the script.

Part 3: Face Mask Model Training (Long Method)

Now that you have your face mask detector up and running, you’re probably wondering, “How does it work?”

Over one thousand photos were used to train the model that detect_mask_webcam.py uses to make the mask or no mask determination. The more examples provided, the better the machine learning because fewer photos = less accuracy.

Photos were divided into 2 folders in our dataset, with_mask and without_mask and the training algorithm created a model of mask vs. no mask based on the dataset. The sample photos provided in the dataset folder you downloaded from GitHub are my own photos.

What if instead of hundreds of photos, we trained our Raspberry Pi Mask Detection system on 20 photos? Fortunately, we have a pre-trained model for you to test out.

From your face_mask_detection folder in your terminal, run the Python 3 code to open up your webcam with the 20 photo model.

python3 detect_mask_webcam.py --model mask_detector-20.model

If you are using a Pi Camera, enter python3 detect_mask_picam.py --model mask_detector-20.model

After a few seconds, you should see your camera view pop-up window and see a green box or a red box. You’ll find this model is not very accurate.

How to train the Raspberry Pi face mask model yourself

As a part of this tutorial, I’ve created a way for you to train the model on your own photos.

In the dataset folder within face_mask_detection on your Pi, check out the two subfolders, with_mask and without_mask.

(Image credit: Tom’s Hardware)

To train the Pi with your photos, simply save your photos (headshots of people wearing or not wearing face masks) to the appropriate folder. Have fun with this and take photos of yourself and your family.

Take your own photos with your Raspberry Pi

1. Open a Terminal, press Ctrl-T.

2. Change directories into the face_mask_detection folder.

cd face_mask_detection

3. Run Python code to take photos of yourself wearing a mask, the same for no mask photos.

If using a webcam run:
python withMaskDataset.py
or
python withoutMaskDataset.py
If using a pi camera run:
python withMaskDataset-picam.py
or
python withoutMaskDataset-picam.py

4. Press your spacebar to take a photo.

5. Press q to quit when you are done taking photos.

(Image credit: Tom’s Hardware)

Running these scripts will automatically save photos into their respective folders, with_mask and without_mask. The more photos you take, the more accurate the model you will create in the next step, but keep in mind, your Raspberry Pi does not have the same computing power as your desktop computer. Your Raspberry Pi will only be able to analyze and process a limited amount of photos due to its compute power and RAM size. On our Raspberry Pi 4 8GB, we were able to process about 1,000 photos, but it took over 2 hours to create the model.

Training the model for Raspberry Pi face mask detection

In this step, we will train the model based on our photos in the dataset folder, but we’ll need to install a few more packages first. The maximum number of photos the train_mask_detector.py script will be able to process will vary depending on your model of Raspberry Pi and available memory.

1. Open a Terminal, press Ctrl-T.

2. Install sklearn and matplotlib packages to your Pi.

sudo pip3 install sklearn

sudo pip3 install matplotlib

(Image credit: Tom’s Hardware)

3. Train the model. Keep in mind that, the more photos you have in the dataset folder, the longer it will take to create the model. If you get an “out of memory” error, reduce the number of photos in your dataset until you can successfully run the Python code.

cd face_mask_detection

python3 train_mask_detector.py --dataset dataset --plot mymodelplot.png --model my_mask_detector.model

(Image credit: Tom’s Hardware)

In our testing, it took over 2 hours to train the model with 1,000 images.

(Image credit: Tom’s Hardware)

In this example, we trained our model with only 20 images, and the confidence/accuracy is rated at about 67%.

After the script finishes running, you’ll see a new file in the face_mask_detector directory: my_mask_detector.model

4. First let’s check to see how accurate our Pi thinks this model will be. Open the newly created image called mymodelplot.png

(Image credit: Tom’s Hardware)

In this image, we trained the model with 1,000 images and the training accuracy was very high.

Testing Your Raspberry Pi face mask model

Now that you’ve trained your model, let’s put it to the test!

Run the same detection script, but specify your model instead of the default model.

From the same Terminal window:

python3 detect_mask_webcam.py --model my_mask_detector.model

If you are using a Pi Camera, enter python3 detect_mask_picam.py --model my_mask_detector.model

How did you do? Let us know in the comments below.

Part 4: Adding a Buzzer and LEDs

Now that we’ve trained our model for Raspberry Pi face mask detection, we can have some fun with the results.

In this section, we add a buzzer and 2 LEDs to quickly identify if someone is wearing their face mask or not.

(Image credit: Tom’s Hardware)

For this step, you’ll add-on:

Small Breadboard
Two 330 Ohm resistors
1 Red LED
2 Green LED
1 Buzzer

1. Wire the LEDs and buzzer as shown in the diagram below. (Always add a resistor between the positive terminal of your LED and your GPIO pin on your Pi.)

a. Red LED will be controlled by GPIO14.

b. Green LED will be controlled by GPIO15.

c. Buzzer will be activated by GPIO 21

d. Connect GND to GND on your Pi.

(Image credit: Tom’s Hardware)

2. Test your LED and buzzer setup by running LED-buzzer.py. Open a new terminal and run the test code by typing:

cd face_mask_detection
python LED-buzzer.py

If you see your LEDs alternate on and off and your buzzer beep. You’ve successfully completed this step and can move on. If the LEDs don’t light up or your buzzer doesn’t work, check your wiring.

(Image credit: Tom’s Hardware)

3. If your buzzer stays on after you have pressed Ctrl-C to exit the python code, run python LED-buzzer-OFF.py to turn off the buzzer and the LEDs.

4. Test the Raspberry Pi face mask detection system In the same terminal, run

python3 detect_mask_webcam_buzzer.py 

If you are using a Pi Camera, enter python3 detect_mask_picam_buzzer.py

If you’re using your own model, add --model my_mask_detector.model as you did in the previous step.

If everything works correctly, when the script detects you are wearing a face mask, the green LED should turn on. If the script detects you are not wearing a face mask, the buzzer should sound along with the red LED lighting up.

(Image credit: Tom’s Hardware)

The possibilities for this project are endless. You could continue to train your model with more photos. You could add a servo motor or activate a gate, when a face mask is detected. Or you could try combining this tutorial with the automated email sending code from the Raspberry Pi Facial Recognition tutorial to send an email with a photo when someone enters without a face mask.

In the latest beta of the next system Apple operating system are references to three Mac systems not yet on the market: whether it is the future machines based on Apple Silicon?

by Andrea Bai published 30 October 2020 , at 19: 01 in the Apple channel

All ‘ inside the code of the latest beta of macOS Big Sur there are references to three new Mac systems that could be released on the market over the next few weeks and could be the first confirmation from Apple of the arrival, by the end of 2020, of systems based on Apple Silicon processors.

References to new Mac systems in the latest Big Sur beta: Apple Silicon coming soon?

The code appeared in beta 1 of macOS Big Sur 10. 0.1 which was released this week to developers. Files signaling the presumable imminent presentation of new Mac systems have appeared in the System / Library folder. In that folder macOS stores bundled files with references to various Mac models, and in the beta released this week are three files with codes that have no match with systems currently available on the market.

MacOS Big Sur 11. 0.1 mentions 3 distinct unreleased Macs, all set for release in 2020. In beta 10 only one of these was present. @ 9to5mac @ appleinsider pic.twitter.com/0u5aGszbWl

— Hans Harck Tønning (@HarckerTech) October 29, 2020

Specifically, as the HackerTech user noted on Twitter, there are MacHardwareTypes files which include the codes 2020 f , 2020 ge 2020 h : the reference code of the MacBook Pro from 16 inch most recent is 2020 de other files in this location refer to the latest MacBook Air, iMac and MacBook Pro models from 13 inches. The reference files contain no data and cannot be analyzed to try to extract information from the models to which they are associated.

Meanwhile, the rumor has been circulating for some weeks according to which Apple has already started work on organizing a new presentation event next November 17. The most likely is for the debut of a new line of MacBook portable systems from 12 inches equipped with Apple Silicon processors based on ARM architecture. For desktop systems, however, we will probably have to wait for the spring of 2021.

Apple seems to be putting another stop to unapproved iPhone repairs: For all models of the new iPhone 12 – from mini to Pro to Pro Max – According to an internal document, it is necessary to carry out a “system configuration” for the first time after replacing the screen or after replacing the camera system. A special app from the manufacturer is required for this, to which only authorized technicians have access, as the repair service provider iFixit reports.

iPhone warning for third-party batteries Such a system configuration is already for the battery replacement in iPhones from year of manufacture 2018 Requirement. If the battery of a third-party manufacturer is used in these models by an independent workshop, the operating system displays a warning for several days that it “cannot be verified that this iPhone has an original battery from Apple,” it says. Information about the battery condition is also not available.

The use of the iPhone will not be affected, emphasizes Apple. The measure is intended to protect the iPhone customer, who is warned of a damaged or “poor quality” battery.

What specific side effects of the unauthorized exchange of the display and camera on the iPhone 12 without subsequently carrying out the system configuration remains open for the time being. According to tests by iFixit, at least the original screens of two iPhone – 12 – models could be exchanged without major side effects. The repair service provider only sometimes received the erroneous warning that the display was “possibly not real”. By switching from LCD to OLED, the approved screen replacement for the iPhone 12 has become significantly more expensive.

Original iPhone parts only recently for independent workshops With the iPhone 12 Pro is it was also possible to insert the camera module of one device into another device, so iFixit. With the iPhone 12 (without Pro) there were considerable problems after the exchange, which made normal use of the camera practically impossible.

Apple has only recently started making original iPhone parts and special tools available to independent repairers if they join Apple’s “Independent Repair Provider Program” and comply with regulations. That should preserve the “safety and quality”, so the group. Previously it was impossible for independent repair shops to obtain original Apple parts.

Microsoft’s operating system will feature a new optional button in the taskbar that will allow you to quickly create and access video conferences on Skype

of Nino Grasso published on 30 October 2020 , at 15: 41 in the Operating Systems channel

Windows Microsoft

Microsoft has released new optional patches for the latest versions of Windows 10 : Windows 10 October 2020 Update (20 H2) and Windows 10 May 2020 Update (2004) . The two updates introduce a new button in the System Tray called Meet Now : this is a feature tested by last September, which is now offered as “optional” but will be distributed to all users with Patch Tuesday next month.

Meet Now is a new Skype feature that allows users to easily schedule a video conference, or group video, with other people. After installing the optional patch, the Meet Now button is presented in the System Tray (in the part of the taskbar applications where services are open in the background) and leads to a browser tab that allows you to start a video meeting via Skype or join a meeting that has already started. The unique feature of Meet Now is that no downloads or Skype account registration is required to join the conference. Anyone can do it.

Below are the release notes for the quality update, known as KB 4580364, which has already appeared on Windows versions 10 above:

Introducing Meet Now in the Windows 10 Taskbar

Earlier this year we introduced Meet Now in Skype. Meet Now makes it easy toconnect with anyone in as little as two clicks for free and each call can last up to 24 hours. Today, we ?? re excited to share that we will be extending this capability inWindows 10 by bringing Meet Now right to the taskbar. In the coming weeks, youwill be able to easily set up a video call and reach friends and family in an instantby clicking the Meet Now icon in the taskbar notification area. No sign ups ordownloads needed.

– Updates an issue that causes a device to stop responding after you have been using a pen for several hours.

Microsoft will bring the new Meet Now button also on Windows 10 May 2019 Update (1903) come on Windows 10 November 2019 Update (1909) . Those who use these versions can already download the optional KB patch 4590836 available from last week via Windows Update.
