The 2018 FIFA World Cup is in full swing, with the last few matches about to take place en route to the Round of 16 on Saturday. While the world’s greatest football players are taking center stage, another main attraction in the tournament is the football world’s latest technology: the Video Assistant Referee.
The Video Assistant Referee or VAR has been adopted in sports like tennis and rugby, and recently by football leagues such as the English FA Cup and the Bundesliga in Germany. Ideally, the VAR helps make decisions for referees much easier and more accurate — especially for crucial, game-changing calls. But is the technology useful and helpful in every possible way?
What is the VAR?
The VAR is a video system that feeds information to referees on the pitch through a wireless earpiece. Assistant referees gather the information away from the stadium and forward these to the referees when a call is contested. The VAR marks the huge step football leagues are taking to digitize football, and has been used since last year.
It utilizes a goal line technology that allows the cameras in the stadium to scan the pitch at every minute. With this technology, movement on the pitch is detected at all possible angles and calls can be made more precisely. Assistant referees inside a control room have access to all these cameras and they send live feed to the pitch via tablet or iPad should the referees want to look at the footage themselves.
The VAR reviews game-changing calls on the football pitch at the time a protest is filed. FIFA lists only four game-changing calls to be considered: goals, penalties, direct red card incidents, and mistaken identity. The VAR checks the validity of these calls and sends the information to the referees. Do note, however, that the referees themselves still have the final decision on what call to make.
The system made its debut in a FIFA Club World Cup in December 2017 between Atletico Nacional and Kashima Antlers. The referee rewarded Kashima with a penalty after reviewing a play inside the penalty box.
Putting the VAR to work
2017 also saw the VAR’s debut in the English FA Cup, but it had its own set of controversies along the way. During a quarterfinal match between Tottenham and Rochdale, a goal by Tottenham was reversed for unclear reasons cited by the VAR. German football league Bundesliga also utilized the VAR during its latest season, but received mixed reactions from players and fans.
In the 2018 FIFA World Cup, the VAR takes center stage as a decision-making aide for referees in the group stages. The first instance was a non-call on a foul by Spain’s Diego Costa in their 3-3 epic against Portugal. Costa would slice the Portugese defense to tie the game at 1-1 at the time, but did so while taking down Pepe from Portugal. After the review from the VAR, the referee stood by his decision to count the goal.
The second instance happened in the France-Australia game when French striker Antoine Griezmann was tackled inside the box, yet the referee called for play to continue. Griezmann received a pass from Paul Pogba, and virtually blitzed through the Socceroo’s defensive line. Griezmann was awarded the penalty after reviewing footage from the VAR as the French went on to win, 2-1.
The third instance was in the Peru-Denmark game when another penalty was awarded to Christian Cuerva of Peru. Denmark’s Yussuf Poulsen tackled the Peruvian in the box, yet the referee called for the play to continue until the incident was reviewed via VAR. However, Cuerva missed the penalty and Poulsen scored in another possession to give the Danish the win, 1-0.
A VAR too high or too low?
While the VAR has only been around for well over a year, it isn’t exempt from both praise and criticism. Many people have shown their praises for the newest technology applied to the football world. The VAR now adds certainty and legitimacy to calls made by referees during matches, instead of them making the same wrong call every time. With football players and managers focusing on the tiniest of details to improve their game, information from the VAR becomes important.
The VAR provides an opportunity for football games to be fair and balanced. Referees now have different vantage points to look at when making calls that ultimately change the outcome of the game. People came to see a quality match wherein the players truly shine, but sometimes the referee’s poor decisions hamper that. In this regard, there is no excuse for not making the right decision with all the video evidence available.
However, a lot of people also have strong feelings against using VAR. While the effort to make the right calls is appreciated, it gets in the way of what makes football so special. When referees call for the VAR — especially with contested goals — fans become anxious instead of jubillant. Usually, fans go into a frenzy the moment the ball goes through the net — no replays needed. It’s as if the game feels all too unrealistic because of all the technicalities.
For football players and coaches, the VAR only adds confusion to fans. Because some football stadiums are built without any big screens, fans become unaware of what’s happening when the referee calls for the VAR. Iran’s coach Carlos Queiroz lambasted the use of the VAR for close, judgment calls — particularly the offside call on his squad in a loss to Spain. He believes that the VAR was put in place to correct obvious mistakes by referees, not debatable calls.
The VAR is a fairly new technology introduced in the world of football, and surely, it’s not perfect. It’s a bold take on digitalizing football, keeping up with the technological demands of today. Because football is decided by people making the right calls at the right time, the VAR becomes an important part in establishing the basis for such calls. The VAR is a useful solution for referees to make the right decisions on the pitch.
However, we must be critical about how the VAR should play in during very crucial moments in the game. The VAR should help give fans a fair yet exciting football match without losing its spirit. With the Round of 16 coming up, all eyes will be on the VAR and whether it will help make the road to the finals interesting or not.
At the end of the day, football fans came to see the best players in the world do what they do best, and no amount of technology should get in the way of that.
A phone’s water protection plan: IP ratings explained
It doesn’t give you the right to dunk it in water, though
If you plan to bring your phone to a beach trip with your friends, you normally bring a pouch with you. The main function of that pouch is to protect your phone from contact with any liquid while you enjoy the waves. Of course, it doesn’t fully guarantee that water won’t seep through it — especially when a big wave crashes on you and opens the pouch. But, it does give a sense of safety and security for your beloved smartphone.
That’s the whole concept behind an IP rating that’s given to most smartphones today. Nowadays, you hear a lot about these smartphones being advertised with IP68 ratings. But, what does an IP68 rating actually mean? Is it worth something to consider when buying a new smartphone?
What is an IP rating?
IP ratings are not new in the tech world. In fact, a lot of the electrical appliances and technologies you have at home come with it. An IP rating, or ingress protection rating basically tells you the level of protection any electrical device has against solid and liquid objects. It acts as a security measure to determine what objects the device can handle without malfunctioning.
The International Electrotechnical Commission (IEC) gives out these ratings to manufacturers as a safety measure for production. It consists of two numbers that describe its protection against a vast number of objects, even human touch. The first number denotes a device’s protection against common solid objects and dust. Meanwhile, the second number denotes a device’s protection against liquids, even steam-jet liquids. The higher the number, the more protection it gets!
IP ratings are not just present in most recent smartphones. Things like electrical sockets, cameras, even phone cases come with IP ratings, as well.
The reason it exists
Manufacturers and consumers see an IP rating quite differently. Those two numbers ultimately stand for how well your device can stand against, well anything. For manufacturers, an IP rating basically gives them a standard to follow when producing more devices. Before shipping their latest smartphones, they subject their devices to numerous tests to validate their IP ratings.
Also, it gives a more concrete way of stating that their devices are resistant to such objects. When you come across smartphones that claim to be water resistant, oftentimes you tend to ask just how resistant it is. With manufacturers, the IP rating gives a more definitive measure to that claim. For example, a smartphone with an IP68 rating is heavily protected against dust, and you can submerge it in waters deeper than a meter — perfect for beach trips.
For consumers, the IP rating just provides a peace of mind when buying a new smartphone. It’s basically placed there to tell you that your phone can still be used even if you subject it to too much dust or water that’s too deep. You see this in most YouTube videos or channels that basically bend, scratch, and dunk phones in buckets of water. In the end, you won’t have to worry about destroying your phone that much when you go on that beach trip without a pouch.
Some manufacturers simply don’t need the rating
However, there are manufacturers that simply found the rating unnecessary or simply just a marketing tool. Companies like OnePlus even did an entire ad that showed off their new flagship devices, the OnePlus 7 and OnePlus 7 Pro without an IP rating. The whole issue sparked debates on whether or not IP ratings do make sense, or companies could simply do without them.
OnePlus argues that one reason their new smartphones don’t have an IP rating is because of the cost to get one. Even simply requesting for a phone for consideration costs a lot on the manufacturing side, which ultimately bumps up the phone’s price. Pete Lau, one of the co-founders of the company estimated the cost for getting an IP rating is at US$ 30. Of course, it is entirely up to the consumer’s view of its value to the overall product.
The other reason is because of the coverage of the device’s warranty, particularly towards water damage. OnePlus claims that even if smartphones have IP ratings that show how resistant they are to water, water damage isn’t fully covered by its warranty. This also furthers their argument on why they wouldn’t want to spend on getting one in the first place. An IP rating is not a legitimate reason for people to have their phones fixed for free after dunking them in buckets of water.
To them, it does not make sense to simply attach an IP rating onto a phone even as a marketing tool. It gives off the wrong impression that the device is waterproof when the rating basically leans towards phones being water resistant.
Do we really need to know the IP rating?
The IEC created IP ratings for everyone’s protection — from manufacturers to consumers. The whole purpose of having an IP rating is to provide a level of protection for anything electrical, smartphones included. It ensures the safety of everyone, but it’s not a way to bail anyone out when they dunk their phones in water.
While some may argue that it helps to know what your device’s IP rating is for better care, others just see it as a marketing ploy. It only seeks to sell a device perceived to be waterproof according to a standard. However, IP ratings were not meant to waterproof your phone by any means. It’s there to tell you that your phone can handle water, just possibly not too much.
At the end of the day, we have to ask ourselves whether we truly see the value in having these IP ratings. Whether or not your preferred device has an IP rating, just remember: it’s not a reason for you to exploit your phone.
Huawei vs the US: A timeline
An FAQ on Huawei’s problems
Who’s afraid of Huawei? Right now, everyone is. Does anyone really know why?
Since 2017, the US has dealt continuous blows against the Chinese company. More than two years later, the war is still in full swing. Both sides have fired multiple salvos against the other. Still, despite the conflict’s longevity, most people are not really sure what’s happening.
Why are they fighting? Should we stay away from Huawei? Is it time to get rid of our Huawei devices as soon as possible? Should we really fear for our cybersecurity?
For ordinary consumers, the entire Huawei debacle is mired in political lingo and endless controversy. It’s time to clear the air. What’s up, Huawei?
How did this all begin?
Let’s go back to where it all started. In late 2017, American lawmakers reviewed the businesses of ZTE, another Chinese tech company. Soon after, the investigation unveiled a flurry of shady business deals involving Iran. By law, companies operating in the US are not allowed to communicate with blacklisted countries including North Korea and Iran. Naturally, the violation caused monumental sanctions against ZTE. The US banned ZTE from American soil — effectively, the same ban on Huawei today.
At this time, Huawei was just a moderately innocent passerby stuck between two fighting giants. At most, Huawei was accused of spying on its customers. American lawmakers proposed a boycott of Huawei’s products. The proposal drew from the emerging rise of Sinophobia. Still, at the time, the US government’s eyes were firmly on ZTE.
In its infancy, the Huawei-ZTE issue was a product of a small fear. It still hadn’t affected everyone. In fact, US President Donald Trump even tried to save both companies from utter destruction. Both companies enjoyed a reprieve from America’s ire. However, this was short-lived.
In a surprising about-face, Trump started his controversial trade war against China. The American leader abandoned his salvific efforts. Instead, he adopted an incredibly aggressive push against Chinese companies. Unsurprisingly, ZTE already crumbled from the initial push, leaving Trump without a company to make an example out of.
Trump set his sights on Huawei, the world’s second largest smartphone maker. His weapon: the same ban meant for ZTE. His motive: potential cybersecurity issues. This time, America means business. Recently, Trump finally pulled the trigger, enacting a total ban against Huawei on American soil. However, instead of just the US, Trump has been lobbying for a similar ban on other countries. Since then, Huawei has suffered a world of hurt.
What does the ban mean?
Naturally, a “total ban” sounds daunting. Banning Huawei smells like certain doom for the tech giant but what does the ban really mean?
When enforced, Huawei can no longer deal with American companies. To Huawei’s dismay, the tech maker uses a fair number of American components in its products. Most notably, Huawei’s smartphones come with Google’s Android. The ban will prevent Huawei from using the operating system going forward. On paper, this is a huge deal. Android remains the world’s biggest operating system. A lot of consumers trust Android. Huawei is losing a massive chunk of its package with the loss.
As if that wasn’t enough, Facebook — and its slew of apps — have withdrawn from Huawei’s products. The company’s smartphones will no longer have Facebook, Messenger, Instagram, or WhatsApp installed out of the box. The threat is becoming real.
It’s not looking good for the Chinese company. Huawei is slowly being dismembered. Faced with an army of bans, it’s natural to worry about Huawei. Worst case scenario, Huawei will become a mere shadow of its former self, devoid of the components that helped its recent success.
Should we really worry, though?
Not just yet. Right now, Huawei is enjoying a temporary reprieve. Soon after the initial ban, the American government granted the company a three-month extension. Until around the end of August, Huawei can still operate with its current partnerships. Except Facebook, its devices will still ship with the same components we love. At least for the near future, Huawei is safe.
In the meantime, Huawei is hunting for adequate alternatives for its failing parts. This means a new operating system, new chips, and likely an entirely new package. To its credit, Huawei’s development team is working around the clock. Only a month removed from ground zero, they are already promising optimistic developments for the future. Huawei remains confident in their future, launching a bevy of new phones amidst the controversy.
Likewise, some American companies are also lamenting the loss of business. Before the ban, Huawei was a loyal customer, delivering American components to a massive global audience. They aren’t happy with Trump’s ban. For one, Google has publicly defended Huawei. According to them, Huawei’s — and subsequently, the world’s — cybersecurity standards will collapse without a collaboration between international companies. With Android, Google can act as Huawei’s checks and balances against potential cybersecurity threats from malicious forces. If anything, Huawei still has its share of public defenders.
Most importantly, Trump still has the power to reverse the ban before the 90-day extension runs out. If China and the US reach a meeting point, all might go back to normal. Though uncertain, it’s too early to give up on Huawei just yet.
What will Huawei 2.0 look like?
Unfortunately, Huawei’s future is muddled with uncertainty. This includes any potential iterations in the future. As far as we know, Huawei isn’t bleeding from the multitude of losses. The company has reinforced its Kirin chipsets. Further, they are developing their own dedicated operating system codenamed Ark OS.
Other than that, there’s not much to go on. Speculatively, the biggest changes will come from its app supports. If Google leaves, Huawei will be left without the Play Store’s support and security. The Chinese company will have to rely on its own native software to power their phones. Unfortunately, an all-Chinese ecosystem is less than ideal for most. In fact, having one might even justify the American Sinophobia. But again, it’s all up in the air.
I have a Huawei phone. Should I just sell it?
No, you still shouldn’t. The grey market is already doubling down against the onslaught of Huawei returns. If you don’t know a willing contact, finding a buyer will be difficult. If you do find one, you’ll receive only a mere fraction of what you paid for.
At its current iteration, Huawei’s phones are still on top. They are a delight to hold and use, and if anything, have challenged its competitors to offer better value to consumers over the years. Right now, it’s best to play the long game. Wait and see what happens. If anything, Huawei — and its official partners — already has an insurance policy in place. Several retailers have declared a 100 percent refund policy in countries like Singapore. If Google cuts the cord, Huawei users can get their money back.
Similarly, Google has promised Android Q support for existing Huawei handsets. Just this week Huawei also announced the rollout of Android-based EMUI 9.1 to older models. If you already own one, a Huawei phone shouldn’t be an immediate cause for panic.
So, should we really be worried about Huawei?
Understandably, uncertainty isn’t an ideal for everyone. Huawei’s troubles are an excruciating thorn for both businesses and consumers alike. Switching to another brand is a natural solution against the company’s shaky future. However, if you’re looking at the silver lining, worrying is likely a premature reaction. If you’re not a Huawei user, the controversies shouldn’t affect you. If you’re already a Huawei user or looking to buy a Huawei device, it will likely pay off to play a longer strategy. After all, Huawei devices are still some of the best smartphones you can buy on the market.
Editor’s Note: Looks like we really shouldn’t worry after all. Not even an entire day has passed since this article was originally published but Huawei no longer banned in the US. Rejoice, Huawei users!
Explaining OLED screens and Dark Mode
Why that screen fits in the dark
Most of the applications you’re currently using must have rolled out their own version of dark mode by now. The smooth transition from a light to dark interface can be done through a push of a button, or by sending the moon emoji on Messenger. A lot of people also find dark mode quite sexy, and that’s probably because of the screen they’re looking at.
A lot of newly released smartphones now have OLED screens, and dark mode seems to work best on such displays! But why is that? How do OLED panels allow dark mode to flourish?
Better, blacker, affordable screens
Organic LED (light-emitting diode) or OLED is essentially a kind of display technology. In a nutshell, OLED panels allow for better and clearer images and colors.
Thin layers of carbon fiber make up OLED screens. Because of these lightweight fibers, screens show brighter and more vibrant colors. Apart from that, OLED screens show deeper blacks and reduce instances of motion blur when navigating. The best part is that OLED screens are becoming gradually cheaper to manufacture. That explains why more and more of today’s smartphones use this panel.
More colorful than the rest
In comparison to regular LED screens of the past, OLED promises more accurate colors by producing light from individual pixels, instead of relying on backlighting. Back then, LCD screens relied heavily on the backlight of the display to make colors pop. Although, such displays also make the colors seem washed, especially when compared to OLED.
However, OLED’s colors don’t always turn out better than on LED and LCD screens. One such case is when you turn your screen’s brightness to its maximum, especially under strong daylight conditions. LED and LCD screens are designed to perform relatively better in color accuracy when your screen’s brightness is set to max. OLED screens were not designed for maximum brightness, so colors at that point would be saturated.
Which OLED is best?
There are two types of OLED technologies that currently exist: AMOLED and PMOLED. A lot of people hear AMOLED tossed around a lot because lots of smartphones use it. Essentially, AMOLED uses a storage capacitor that controls how much light each individual pixel will give off. It’s the one responsible for projecting all sorts of vibrant colors on most OLED smartphone screens. Apart from that, AMOLED screens do support wider resolutions at a more affordable and efficient rate.
PMOLED, on the other hand, does not have a storage capacitor and instead relies on user control. Essentially, the user will control lighting settings, and the individual pixels will adjust accordingly. You can find PMOLED screens on smaller devices like older iPods and pocket Wi-Fi devices. Take note that these screens use more power to implement such color changes.
Joining the dark side
Ever since dark mode rolled out for different apps and interfaces, people have been contemplating on switching to it — and for good reason. On normal LED or LCD screens, the new feature does not bode well with the technology. The depth of the black their dark mode possesses is not reflected well, to the point that the blacks look more gray than actual black. This is much more obvious when the screen’s brightness is turned all the way up.
Aesthetically, dark mode looks better on OLED screens because of the technology’s emphasis on deeper blacks. Most OLED screens have capacitors that control light passing through each pixel, which also works for blacks and whites. As such, dark mode shows up deeper and blacker, which is the intended look compared to regular modes. But, there’s actually more to just aesthetics for this mode.
It’s also been proven that dark mode on OLED helps save your battery life. Google confirmed this at its Android Dev Summit, citing that on max brightness, blacks consume less power than all other colors. Individual pixels need less electricity to show blacks on screen, which results in lower power consumption through time. Note that Google got these findings through tests on their original Pixel smartphones and their own apps like YouTube.
What’s left for OLED and dark mode
Apps and operating systems are now starting to embrace or consider incorporating dark mode into their software. While apps like Twitter and YouTube introduced such an option early on, others are beginning to take notice. Of course, you’re gonna need the right screen to fully immerse yourself.
It has been proven: OLED and dark mode are indeed a perfect match. But, it is entirely up to you whether you want to stay in the light or switch to the dark side.
