"Global temperatures have been rising for decades," reports the Washington Post. "But many scientists say it's now happening faster than ever before." According to a Washington Post analysis, the fastest warming rate on record occurred in the last 30 years. The Post used a dataset from NASA to analyze global average surface temperatures from 1880 to 2025. "We're not continuing on the same path we had before," said Robert Rohde, chief scientist at Berkeley Earth. "Something has changed...." Temperatures over the past decade have increased by close to 0.27 degrees C per decade - about a 42 percent increase... For decades, a portion of the warming unleashed by greenhouse gas emissions was "masked" by sulfate aerosols. These tiny particles cause heart and lung disease when people inhale polluted air, but they also deflect the sun's rays. Over the entire planet, those aerosols can create a significant cooling effect - scientists estimate that they have canceled out about half a degree Celsius of warming so far. But beginning about two decades ago, countries began cracking down on aerosol pollution, particularly sulfate aerosols. Countries also began shifting from coal and oil to wind and solar power. As a result, global sulfur dioxide emissions have fallen about 40 percent since the mid-2000s; China's emissions have fallen even more. That effect has been compounded in recent years by a new international regulation that slashed sulfur emissions from ships by about 85 percent. That explains part of why warming has kicked up a bit. But some researchers say that the last few years of record heat can't be explained by aerosols and natural variability alone. In a paper published in the journal Science in late 2024, researchers argued that about 0.2 degrees C of 2023's record heat - or about 13 percent - couldn't be explained by aerosols and other factors. Instead, they found that the planet's low-lying cloud cover had decreased - and because low-lying clouds tend to reflect the sun's rays, that decrease warmed the planet... That shift in cloud cover could also be partly related to aerosols, since clouds tend to form around particles in the atmosphere. But some researchers also say it could be a feedback loop from warming temperatures. If temperatures warm, it can be harder for low-lying clouds to form. If most of the current record warmth is due to changing amounts of aerosol pollution, the acceleration would stop once aerosol pollutants reach zero - and the planet would return to its previous, slower rate of warming. But if it's due to a cloud feedback loop, the acceleration is likely to continue - and bring with it worsening heat waves, storms and droughts. "Scientists thought they understood global warming," reads the Post's original headline. "Then the past three years happened." Just last month Nuuk, Greenland saw temperatures over 20 degrees Fahrenheit above average, their article points out. And "Parts of Australia, meanwhile, have seen temperatures push past 120 degrees Fahrenheit amid a record heat wave..."

Doom scrolling is doomed, if the EU gets its way. From a report: The European Commission is for the first time tackling the addictiveness of social media in a fight against TikTok that may set new design standards for the world's most popular apps. Brussels has told the company to change several key features, including disabling infinite scrolling, setting strict screen time breaks and changing its recommender systems. The demand follows the Commission's declaration that TikTok's design is addictive to users -- especially children. The fact that the Commission said TikTok should change the basic design of its service is "ground-breaking for the business model fueled by surveillance and advertising," said Katarzyna Szymielewicz, president of the Panoptykon Foundation, a Polish civil society group. That doesn't bode well for other platforms, particularly Meta's Facebook and Instagram. The two social media giants are also under investigation over the addictiveness of their design.

An anonymous reader shared this report from the Register: Telcos likely received advance warning about January's critical Telnet vulnerability before its public disclosure, according to threat intelligence biz GreyNoise. Global Telnet traffic "fell off a cliff" on January 14, six days before security advisories for CVE-2026-24061 went public on January 20. The flaw, a decade-old bug in GNU InetUtils telnetd with a 9.8 CVSS score, allows trivial root access exploitation. GreyNoise data shows Telnet sessions dropped 65 percent within one hour on January 14, then 83 percent within two hours. Daily sessions fell from an average 914,000 (December 1 to January 14) to around 373,000, equating to a 59 percent decrease that persists today. "That kind of step function - propagating within a single hour window - reads as a configuration change on routing infrastructure, not behavioral drift in scanning populations," said GreyNoise's Bob Rudis and "Orbie," in a recent blog [post]. The researchers unverified theory is that infrastructure operators may have received information about the make-me-root flaw before advisories went to the masses... 18 operators, including BT, Cox Communications, and Vultr went from hundreds of thousands of Telnet sessions to zero by January 15... All of this points to one or more Tier 1 transit providers in North America implementing port 23 filtering. US residential ISP Telnet traffic dropped within the US maintenance window hours, and the same occurred at those relying on transatlantic or transpacific backbone routes, all while European peering was relatively unaffected, they added.

January was a busy month for Haiku, with their monthly report listing a metric ton of smaller fixes, changes, and improvements. Perusing the list, a few things stand out to me, most notably continued work on improving Haiku's touchpad support. The remainder of samuelrp84's patchset implementing new touchpad functionality was merged, including two-finger scrolling, edge motion, software button areas, and click finger support; and on the hardware side, driver support for Elantech "version 4" touchpads, with experimental code for versions 1, 2, and 3. (Version 2, at least, seems to be incomplete and had to be disabled for the time being.) ↫ Haiku's January 2026 activity report On a related note, the still-disabled I2C-HID saw a number of fixes in January, and the rtl8125 driver has been synced up with OpenBSD. I also like the changes to kernel_version, which now no longer returns some internal number like BeOS used to do, instead returning B_HAIKU_VERSION; the uname command was changed accordingly to use this new information. There's some small POSIX compliance fixes, a bunch of work was done on unit tests, and a ton more.

We often lament Microsoft's terrible stewardship of its Windows operating system, but that doesn't mean that they never do anything right. In a blog post detailing changes and improvements coming to the Microsoft Store, the company announced something Windows users might actually like? A new command-line interface for the Microsoft Store brings app discovery, installation and update management directly to your terminal. This enables developers and users with a new way to discover and install Store apps, without needing the GUI. The Store CLI is available only on devices where Microsoft Store is enabled. ↫ Giorgio Sardo at the Windows Blogs Of course, this new command-line frontend to the Microsoft Store comes with commands to install, update, and search for applications in the store, but sadly, it doesn't seem to come with an actual TUI for browsing and discovery, which is a shame. I sometimes find it difficult to use dnf to find applications, as it's not always obvious which search terms to use, which exact spelling packagers are using, which words they use in the description, and so on. In other words, it may not always be clear if the search terms you're using are the correct ones to find the application you need. If package managers had a TUI to enable browsing for applications instead of merely searching for them, the process of using the command line to find and install applications would be much nicer. Arch has this third-party TUI called pacseek for its package manager, and it looks absolutely amazing. I've run into a rudimentary dnf TUI called dnfseek, but it's definitely not as well-rounded as pacseek, and it also hasn't seen any development since its initial release. I couldn't find anything for apt, but there's always aptitude, which uses ncurses and thus fulfills a similar role. To really differentiate this new Microsoft Store command-line tool from winget, the company could've built a proper TUI, but instead it seems to just be winget with nicer formatted output that is limited to just the Microsoft Store. Nice, I guess.

The team behind Tyr started 2025 with little to show in our quest to produce a Rust GPU driver for Arm Mali hardware, and by the end of the year, we were able to play SuperTuxKart (a 3D open-source racing game) at the Linux Plumbers Conference (LPC). Our prototype was a joint effort between Arm, Collabora, and Google; it ran well for the duration of the event, and the performance was more than adequate for players. Thankfully, we picked up steam at precisely the right moment: Dave Airlie just announced in the Maintainers Summit that the DRM subsystem is only "about a year away" from disallowing new drivers written in C and requiring the use of Rust. Now it is time to lay out a possible roadmap for 2026 in order to upstream all of this work. ↫ Daniel Almeida at LWN.net A very detailed look at what the team behind Tyr is trying to achieve with their Rust GPU driver for Arm Mali chips.

While starting this post I realized I have been maintaining personal infrastructure for over a decade! Most of the things I've self-hosted is been for personal uses. Email server, a blog, an IRC server, image hosting, RSS reader and so on. All of these things has all been a bit all over the place and never properly streamlined. Some has been in containers, some has just been flat files with a nginx service in front and some has been a random installed Debian package from somewhere I just forgot.
