Apple's WebKit performance tax leaves iOS browsers stuck in the slow lane, says Microsoft

1 Comment
Critics and competitors have long complained about the "Apple Tax" – the sales commission developers are obliged to pay on App Store sales and in-app purchases. Now Microsoft engineers have documented a performance tax – the performance hit that iOS users today endure because Apple requires iOS browsers, with theoretical exceptions, to use the WebKit browser engine that powers Safari. The performance tax comes to 28.6 percent, almost as much as Apple's 30 percent commission rate. Browser rendering engines handle the heavy lifting for web browsers. "They determine how web standards are implemented, how security and privacy protections are enforced, and which actors ultimately shape the evolution of the web," as Mozilla recently explained. Just three major engines dominate commercial deployments: Blink, the foundation of Chrome and its Chromium-based siblings Edge, Vivaldi, Brave, and Opera, among others; WebKit, the foundation of Safari; and Gecko, the foundation of Firefox. Firefox holds about 2 percent of the global browser market share, according to StatCounter. That helps explain Mozilla's concern that the lack of browser engine diversity, a consequence of the market power of Google and Apple, threatens the open web. According to DigitalApplied, Safari owns 23.4 percent of mobile browsing on iOS globally and 51.2 percent of mobile browsing in North America. But due to Apple's platform rules, every browser that runs on iOS is WebKit-based, so there are few opportunities for competitive differentiation outside of interface elements. Browser rivals, advocacy groups, and web developers have argued that Apple should relax its platform rules and improve its web technology for years. Europe's Digital Markets Act (DMA), plus regulatory action in Japan and elsewhere, have amplified hope that Apple will allow more competition on its mobile OS. The latest such investigation comes from the Italian Competition Authority. Microsoft has now highlighted the cost of the iOS browser engine monoculture – time lost to Safari's slowness. On Monday, Kyle Pflug, group product manager for the Microsoft Edge Web Platform, published benchmark test results using Apple's Speedometer 3.1 and other test tools that show how a Chromium-based iOS browser using the open source Blink rendering engine compares to Apple's Safari browser, which relies on the open source WebKit rendering engine. Edge is a Chromium-based browser, and if it were implemented for iOS using BrowserEngineKit, a framework Apple introduced in March 2024 to comply with Europe's Digital Markets Act (DMA), it would score 28.6 percent better (49.27 vs 38.3 on Speedometer 3.1) than Apple's Safari browser under iOS 26.5.1. It would also outperform Safari on the JetStream 3 benchmark (JavaScript and Wasm performance) by 13.1 percent (306.35 vs 270.9) and on the MotionMark 1.3.1 benchmark (graphics rendering) by 2.1 percent (4,773.52 vs 4,673.68). "To be clear, this is a research prototype, not a product announcement; and these are preliminary numbers from my own device, not lab results," said Pflug. "But it does prove out the opportunity to close real capability gaps and deliver new competition on performance." Rick Byers, principal Chrome engineer at Google, took note of the results. "Given how Chromium and WebKit are always vying for the top spot in Speedometer on macOS, it's really striking how big the gap is on iOS!" he said in response to Pflug's post. "And we haven't even really tried to optimize performance for that platform yet! IMHO this is what you should expect to see when there's a lack of competition!" Apple did not immediately respond to a request for comment. The EU has enforced competition through browser selection screens, with some success. In theory, the bloc's rules should promote browser engine competition on iOS. The DMA allows EU-based developers to build browsers with rendering engines other than WebKit. Since March 2024, Apple has provided tools to do so. Yet more than two years later, no browser maker has launched an alternative browser. As Microsoft has done with Edge, Google and Mozilla have prototyped Blink and Gecko-based versions of their respective browsers for iOS. But no such browser has been released. That may be because building a new browser means scaling considerable technical hurdles that Apple hasn't rushed to lower, such as BrowserEngineKit bugs. Browser makers therefore consider the Apple rule compliance process too onerous. For example, if Microsoft were to release a Blink-based version of Edge on iOS, it would have to be a separate app from the WebKit-based version of Edge – leaving Redmond to reacquire its entire iOS user base. Alex Moore, executive director of Open Web Advocacy, a group that has lobbied on behalf of web developers against Google and Apple's platform rules, pointed to citations [PDF] in US court filings (the US 2024 antitrust case against Apple is ongoing) and UK regulatory documents that highlight the problem posed by Apple's platform power. In February 2020, these documents say, Apple's vice president of iPhone marketing proposed that the company should "set a stake in the ground for what features we think are 'good enough' for the consumer" rather than investing and innovating. "This is a clear example of the costs Apple imposes on consumers and businesses worldwide, costs created by its 17-year ban on competing browser engines," Moore told The Register. "Even in the EU and Japan, where Apple is now required to allow browser vendors to use their own engines, the barriers it has put in place ensure browser vendors are prevented from porting their own engines to iOS. Given that Apple has now had more than two years to produce a compliant solution, the European Commission needs to open a specification proceeding to instruct Apple, in precise terms, how these barriers must be removed." "If Apple can restrict browser engines on iOS, it can limit what the mobile web is capable of, and keep businesses dependent on native apps and app store rules. This is, in our view, the most critical intervention the EU could possibly make, and the one most likely to reshape the entire mobile ecosystem. No other intervention comes close." ®

Holy git! Microsoft code-sharing site suffers downtime, despite move to Azure

1 Comment
GitHub has been struggling with service availability in recent months as traffic on the platform has surged, driven in large part by AI-assisted coding and agentic development workflows. The code-sharing site has been trying to address those issues by expanding capacity and migrating more workloads to Azure infrastructure, but reliability remains uneven. In the May 2026 GitHub Availability Report, GitHub acknowledges nine incidents that degraded performance, one fewer than its April report. That's something. But Jakub Oleksy, SVP of software engineering at GitHub, says there's more to be done. "We are making structural changes that permanently remove failure modes," he said in the report. "We acknowledge that we have work to do, but we’re committed to getting it done and making GitHub reliable when and where you need it." Microsoft’s code hosting site also briefly halted new Copilot subscriptions to reduce the cost impact of its AI services and to adjust its Copilot pricing to account for shifting model provider policies. As noted in an April post, GitHub had planned to increase its capacity by 10x back in October 2025, but by February 2026 it had become evident that a 30x expansion would be needed to accommodate the surge of pull requests, commits, and new repos. Last year, GitHub reportedly handled 1 billion commits for the entire year. Now it receives 1.4 billion commits every month. “We’re now serving 40 percent of monolith traffic from Azure (up from 8 percent in February), with Git traffic at 30 percent and repository replication at 99 percent,” said Oleksy. “We’ve more than doubled our effective capacity in four months.” Oleksy notes that efforts to isolate GitHub’s primary database cluster by moving users, authentication, and authorization into separate domains should prevent failures that cascade across the system. That hasn’t quite solved GitHub’s ongoing availability challenges, in part because Azure has also confronted capacity problems recently. There were nine incidents in May compared to 10 incidents in April. And June is on pace for a similar number. The Missing GitHub Status Page, an unofficial project to track GitHub service problems, counts 12 incidents in May and reports uptime over the past 90 days at 87.26 percent. By month, the project puts GitHub availability at 78.33 percent in April, 93.86 percent in May, and 88.39 percent for June so far. GitHub's Official Status Page presents a far more flattering view of availability, with uptime figures mostly around 99.9 percent for the listed services. These figures depend upon what gets counted and the duration of the disruption. GitHub’s own incident history page cites 26 incidents in April, 23 in May, and 12 to date in June. ®

That an app 'Fits on a Floppy' is still a useful measure in 2026

1 Share
If you're old enough, you might remember using floppy disks, either of the 3.5-inch or 5.25-inch variety. They didn't hold much and often you had to have many disks to install one program. Don't be misled by Fits on a Floppy's retro-tech name: it is most definitely not about 20th century data media. It's about compactness and comprehensibility. Fits on a Floppy describes itself as "a Manifesto for Small Software," and as we read it, we found ourselves nodding in agreement, right from the opening line: That is certainly the impression of this author, and it is not just us. We are irresistibly reminded of the Red Hat developer's six waves of industry BS that we recounted in February. Like any eternal verity of the computing industry, there's even an XKCD comic about it, if you needed any more persuading. XKCD's own internal citations, both about voting machines and indeed about the use of the blockchain, reinforce the message. Randall Monroe spells it out: That sounds about right. And parenthetically, anyone who says that they can improve anything with either blockchain or AI is no more to be trusted than a schoolteacher who gives no homework. A year before that Red Hat engineer talked to us about waves of industry BS, Dutch consultant Bert Hubert talked to The Reg about digital sovereignty – and he feels similarly. In 2024, he wrote A 2024 Plea for Lean Software in tribute to the great Niklaus Wirth, who passed away earlier that month. In our own obituary for Professor Wirth, we mentioned the 1995 paper that inspired Hubert: A Plea for Lean Software (this is a PDF of a scan – but we have posted a more readable plain text version here). One of the lasting effects of that paper is what is now called Wirth's Law: Sadly, that seems to have been its main impact. As a usable demonstration of his 2024 "plea," Hubert offered a working example, which he explained in Trifecta Technology. It's a web image-sharing tool, implemented in under 2000 lines of code. There's also a page for the Trifecta app itself, which comes in as a 1.7 MB compressed Docker file. (With some clever disk formatting, you could get that on a 1.4 MB floppy.) There are, as that anonymous Red Hatter observed, so many different layers of unnecessary complication and plain old marketing lies in modern IT that it is now hard to even keep track of them. One point of the Fits on a Floppy idea is that if you impose an artificial limit on project size, merely by keeping it very small, you will be forced to keep it very simple. That simplicity is the goal here, not fitting on 1980s physical media. You might react with scorn when you hear the idea that in the 2020s, anything useful could fit into under 1.5 MB. When even a leading tool to write an ISO file onto a USB key is a hundred times that size, it sounds absurd. But it really is not. The mind behind the manifesto is developer Matt Sephton, and he offers 18 tiny but useful apps that he's written to prove his point – plus a screensaver which we feel sure is an hommage to Berkeley's classic Flying Toasters screensaver. Others are still making useful single-floppy-sized apps today. We wrote about the revival of the Dillo web browser, and at last year's FOSDEM, the project lead was handing out floppies with the latest release. The whole app, on one diskette. Drew DeVault's Hare programming language is still in development, but when it reaches version 1.0, he plans to sell copies on a floppy: Another tiny modern language is the Janet Language. It's not quite so small, but its just over 2MB download could fit onto the 2.8 MB floppies that were used in later IBM PS/2 models and the NeXTstation. The real point here is about the readability and long term maintainability of compact, even minimalistic code. It's a similar point to that made in Dave Gauer's Ascetic Computing essay, which we cited and linked to when looking at OpenBSD 7.9. Small size and simplicity is what Fits on a Floppy is really talking about, not about physical media. He explicitly spells it out for the hard-of-thinking: Bert Hubert too returned to this theme when he wrote a piece On Long Term Software Development. At this year's Open Source Policy Summit, we saw some pundits pontificating that to escape the US cloud, the answer was that Europe needed its own companies running their own datacenters running Europe's own domestic cloud. This is so manifestly Getting The Wrong End Of The Stick that it put us in mind of Wolfgang Pauli's famous line: "That is not only not right; it is not even wrong." The way to escape a broken model that was a bad idea in the first place is not to make your own sovereign version. All you're doing is locking yourself in your own personal cage. The smart answer is to discard the broken model, and go back to an older, simpler model where organizations own and store their own data on their own servers. As ever, the KISS Principle is one of the best guidelines. It's Occam's Razor in reverse: the best solution is the simplest possible solution. If the problem is that you are trapped in someone else's cloud, then don't switch to another cloud and risk it happening again: get your private data out of the cloud altogether. Just Use One Big Server. Hire some grumpy old techies with grey hair (or none) to run it – there are plenty out there, but ageism keeps them out of work. At the smallest and most local end of this scale, then one useful guiding principle is to just keep the tools as small as you can possibly make them. It's an artificial limit, but that does not lessen its validity. It's not the only way. It may not even be the best way. But it's a way, a simple, clear, obvious way – and there's nothing to prevent anyone finding their own different path to radical simplicity. The PC rose to greatness running on two 360 kB floppy drives – hard disk drives only came along later. Tools like Lotus 1-2-3 redefined business management running on one 360 kB disk, with a second 360 kB data disk in drive B: – and this vulture is willing to bet that some spreadsheets built on such machines, long since converted to Microsoft Excel, are still running multinationals, and indeed nations, today. Compared to that, 1.4 MB is luxurious. ®

20 Of The Most Savage Comebacks By George Takei

1 Share

From intergalactic fame to big Internet name, George Takei has become a crusader against hate on social media - and resistance is futile.

While George carved out most of his legacy as Hikaru Sulu in the original Star Trek series, he's found a new life at 79 years-old as one of the most 'liked' people on Facebook, with over 10 million fans hanging off his every post. He's supremely witty, and is never short on scathing comebacks when Internet trolls attack.

George is also an outspoken advocate for LGBTQ rights and racial equality. As both a gay man and a Japanese-American growing up during World War II, he's seen his fair share of discrimination, and he fights against it fiercely. He recently launched a Care2 petition asking people to stand up for Muslims in the US aimed at the incoming president, Donald Trump, and is less than 3000 supporters away from achieving his goal of 160,000.

Live long and prosper, George! (h/t)

49 Stunning Photos Of Lisbon’s Street Art That Prove Why This City Is The Unofficial Graffiti Capital Of The World

1 Comment

If you’ve ever wandered the hilly, tile-covered streets of Lisbon, you know the city itself is basically a living, breathing gallery—but keeping up with its ever-changing walls is a full-time job. Enter Luis Rodrigues, the dedicated curator behind the Instagram powerhouse Street Art Lisbon, where he meticulously documents the city’s vibrant urban soul across a staggering 18,000+ posts.

While Luis is quick to remind his 55,000+ followers that he isn't the artist behind the spray cans, his page has become the definitive digital archive for everything from massive, multi-story murals to those blink-and-you’ll-miss-it stencils hidden in the Alfama district.

91-Year-Old Grandma Uses Microsoft Paint In A Way That Would Probably Surprise Even Its Developers (New Pics)

1 Comment

It is never too late to start learning a new skill or searching for a brand new hobby. Learning really doesn’t just stop and end immediately after high school or university, and Spanish grandmother Concha García Zaera is proof of this.

The incredibly talented artist from Valencia has been wowing the internet with her incredibly detailed works of art, all done exclusively on Microsoft Paint. Now we’ve all spent quite a lot of time in the program as kids (and, let’s be honest, as adults), but very few of us have approached this level of mastery.

We’ve collected some of Concha’s newest masterpieces for you to gaze at, dear Pandas, so go on and have a look. Upvote the ones you liked the most, let us know which ones resonated with your hearts the most, and be sure to show your love to the artist by following her Instagram account.

I wanted to learn more about lifelong learning and staying bright as we age, so I reached out to Age UK, the country's leading charity that's dedicated to helping everyone make the most of later life. A representative of the charity was kind enough to answer my questions. You'll find Bored Panda's full interview below.

Unfortunately, beloved grandmother and artist Concha passed away on July 20, 2023, at the age of 93.

Artist Concha is very humble. In her Instagram bio, she presents herself in a very simple and wholesome way. “I am a 90-year-old lady. I like to paint with the Paint program. And above all to be with my family and with my friends,” she writes. However, her 91st birthday was on June 12 (she was born in 1930), so we assume she simply didn't have the time to update her bio.

Currently, the Spanish grandmother has a whopping 301k followers on Instagram and her circle of fans keeps growing. Back in 2018, when Bored Panda first wrote an article about Concha’s Paint artwork, she had 108k followers. This just goes to show that she creates art that’s the perfect mix of quality and popular appeal.

But above all, Concha’s skills prove to us that we really can do anything and at any age, given that we put in enough time and dedication. Persistence and focus are key here.

One of Concha’s granddaughters convinced her to create an account on Instagram in 2017 and that step has ensured that people have been able to enjoy her colorful and detailed Paint drawings ever since.

The grandmother’s journey into the world of Paint began more than a decade earlier after her husband fell ill and later sadly passed away. Her family gave her an old computer and she started spending time on the Paint program to keep herself busy.

“I have no imagination at all, so I get inspiration from the postcards that my husband used to send me or drawings that I find and like,” Concha told Vanguardia. It takes her roughly two weeks to finish a single work of art. Something else that inspires her is her beautiful hometown of Valencia. You can really see her love for the city in the care she puts into each and every Paint brushstroke.

Concha remains very humble about her skills and believes that her drawings are “simple things” and she can’t fathom why they get so much attention.

"Hobbies add color and variety to all our lives so it’s good to help to inspire others to take up new interests. New hobbies and interests can help maintain social connections and reduce feelings of loneliness and it’s a great way to learn new skills. Taking part in social activities may help us to stay sharp in later life," a representative of Age UK told Bored Panda about the importance of developing hobbies, especially within in a social context.

If you're living in the UK, you can get in touch with your local Age UK on behalf of your older relatives to find out what they have to offer. They have a huge variety of different activities available that even I'm jealous of. Each local branch of the charity has its own unique timetable of clubs and classes, including: Arts & Crafts, Bridge group, Coffee morning, Men in Sheds, Photography club, Pub lunch, Quizzes, Tea dance, Computer lessons, etc.

"If joining clubs and classes are not an option, or your loved one doesn’t feel ready to start going outside yet, there are still ways to help them engage with new hobbies. Making sure older family members have everything they need to take up or continue hobbies, such as arts and crafts or wool if they are a keen knitter, ingredients if they are a budding chef or even the right tools for DIYing, can help," the Age UK rep told Bored Panda.

"Doing activities together such as the gardening can be a great incentive too, or maybe help them research locally to see if there is a neighborly Book Club dial-in they could join. If your loved one finds it hard to stay physically active, or doesn’t know where to start, take a look at Age UK’s information on keeping active, which has ideas of activities for everyone. Even encouraging older friends and relatives to settle in with a favorite book or audiobook, do some cooking, listen to the radio while doing a puzzle, or tuning in to an afternoon radio play can help emotional wellbeing and mental health."

Our hobbies don't just keep us engaged—they can be a path toward living a higher quality life. "Having a hobby or learning new skills, whatever form they take, is important. And while for many they provide a nice way to spend spare time and an opportunity to interact with friends over a shared pursuit, for those with less social contacts it can give life a real sense of purpose and routine."

According to the Age UK representative, we can 'exercise' our brains by doing mentally stimulating activities, from puzzles to games. "If we want our brain to stay in peak condition, we should use it. In fact, one of the theories about reducing or delaying cognitive aging is referred to as the 'use it or lose it' theory. Research shows that things like learning languages helps keep us brighter as we age. It is just as important to look after your brain by exercising your thinking skills, as you would do physical exercise to look after your body."
