Europe: The World's Fastest-Warming Continent

fjo3 shares a report from the AFP: The latest heatwave sweeping across Europe is a stark reminder that it is the world's fastest-warming continent, stretching into an Arctic that is heating at an even greater pace. Britain, France, Italy and Spain have issued red alerts and health warnings for much of their territory this week as the region endures its second heat episode since May. Here is a look at why Europe is warming faster than elsewhere: The planet as a whole is around 1.4C warmer than in preindustrial times, defined as 1850-1900. By comparison, Europe is around 2.4C hotter than the preindustrial era, according to the EU's Copernicus Climate Change Service. The long-term rise in global average temperatures is mainly due to greenhouse gas emissions from burning oil, gas and coal, but it varies by regions due to a combination of factors. Land warms faster than the ocean as water can absorb more heat and cool through evaporation. Shifts in atmospheric circulation have driven more frequent and more intense heatwaves in the European summer, according to Copernicus. High-pressure systems, which bring settled weather and higher temperatures, have become more common in Europe, Copernicus director Carlo Buontempo said. [...] Another major reason is geography as Europe is connected to the Arctic, which is 3.2C warmer than in preindustrial times. The region's rising temperatures are partly due to a process known as the albedo feedback. Bright snow and ice reflect much of the sun's heat back into space, but as they melt they reveal darker, heat-absorbing surfaces such as land and the ocean. In other parts of Europe, areas where snow was very frequent in winter have seen this coverage shrink, exposing dark land. Stricter air quality regulations have reduced aerosol emissions since the 1980s. But tackling the pollutant had the side effect of contributing to global warming, as these tiny airborne particles have a cooling effect by reflecting sunlight and making clouds more reflective.

US AI Stock Sell-Off Shakes Markets From Wall Street To Asia

An anonymous reader quotes a report from The Guardian: A tech sell-off shook global markets on Tuesday as attention turned away from developments in the US war with Iran and toward the future of AI companies and chipmakers that have driven stock markets to record highs. The tech-heavy Nasdaq index closed 2.2% lower on Tuesday. The S&P 500 was also down by Tuesday afternoon, dropping 1.43% while the Dow remained steady. All three major US indices have hit record highs this year, riding off a rush of funding to support AI technology and infrastructure. Nasdaq is up 10% for the year, while the Dow jumped 6% so far this year, breaching past 51,000 points, and the S&P 500 is up 7.3%. But some economists have warned that the influx of AI spending is a bubble reminiscent of the dot-com bubble that burst in the early 2000s. Seven tech companies make up 30% of the S&P 500's value. The heavy reliance on a single industry and a few key companies has some investors wondering if it's a matter of when, not if, there will be a burst. Those concerns have been heightened by signals from the Federal Reserve last week that it may increase interest rates, and therefore the cost of borrowing, in order to tackle rising inflation. Alphabet fell 5% on Monday. SpaceX plunged 16%. The selloff also spread to Asia, with South Korea's benchmark dropping 10% as SK Hynix and Samsung Electronics each lost more than 12%, while Japan's Nikkei 225 declined 3.5%.

29-Year-Old Squid Proxy Bug 'Squidbleed' Can Leak Cleartext HTTP Requests

A 29-year-old bug in the Squid web proxy, dubbed Squidbleed and tracked as CVE-2026-47729, can let an authorized proxy user retrieve fragments of another user's cleartext HTTP requests, including credentials and session tokens. The security researcher who reported the flaw credited Anthropic's Claude Mythos Preview for the discovery. The Hacker News reports: Squid describes this as an attack by a trusted client: someone already permitted to use the proxy, not any random host on the internet. That matches Squid's usual home, shared networks like schools, offices, and public Wi-Fi. In those setups, the attacker is just another user of the same proxy. The leak also only reaches traffic that Squid can read. Normal HTTPS rides an opaque CONNECT tunnel, so Squid never sees inside it; the exposed traffic is cleartext HTTP, plus TLS-terminating setups where Squid decrypts and inspects. The attacker also needs the proxy to reach an FTP server they control on port 21. Both FTP and that port are on by default. [...] If you patch, verify the fix, not just the version. Confirm the guard is in FtpGateway.cc, or check your distribution's backport, since distros ship their own builds (Debian packages Squid 5.7). The public thread is still inconsistent: maintainer Amos Jeffries first said Squid 7.6 carried the fix, then corrected that to 7.7, and on June 22 Debian's Salvatore Bonaccorso noted the referenced commit looks like it is already in 7.6. The fix is small, a null-terminator check before the vulnerable strchr calls, merged to the development branch in April and v7 in May. Squid 7.6 does separately patch CVE-2026-50012, an unrelated cache_digest heap overflow. The cleaner move is the one the researchers recommend anyway: turn FTP off. Chromium dropped FTP years ago, and most networks carry almost none of it, so disabling it removes this attack surface for free, whatever build you run. The risk is real but bounded. SUSE rates it moderate, CVSS 6.5, and the vector explains the score: the attacker needs proxy access (low privileges), and the only impact is confidentiality, nothing on integrity or availability.

In memory of the man who put red and green squiggles under words

Every little thing in a graphical user interface that we take for granted today, no matter how small, was thought up by someone, at some point. Case in point: the little red squiggly lines underneath misspelled words. In one form or another, these are everywhere now, and have just become a regular staple of every single text editing field we encounter every single day and don't stop to think about. Still, they were invented by someone, and we happen to know exactly who that was: Tony Krueger. In early versions of Word, the Spell Check feature was something that you explicitly invoked, and then you had to sit and wait while the program looked for all your potentially-misspelled words, and then showed them to you one at a time for a decision on what to do for each one. Word did introduce an Auto Spell Check feature to run spell check when the user was idle, so that when you hit the Spell Check button, the results were ready to go. However, the Auto Spell Check was still a blocking operation. As a result, a lot of users turned it off because it always seemed to decide "Now would be a good time to spell-check the document" just as you wanted to do something, forcing you to wait for the spell check pass to complete before you could, say, save and exit. Tony made the spell checker much more unobtrusive so that it didn't interfere with your foreground work. And when it found a problem, instead of waiting for you to trigger a spell check, it immediately drew red squiggles under potentially-misspelled words (and later green squiggles under potential grammatical errors). ↫ Raymond Chen at The Old New Thing Tony Krueger passed away recently, after, among other things, having worked on an dizzying number of Microsoft Word releases. Imagine coming up with something that seems to basic and elementary to us now, and seeing it spread pretty much everywhere. I wonder what it must feel like to have invented something that seems so simple, most people don't even realise they use it every single day.

KDE is going to fix network shares

I've had my share of issues with network shares on any operating system, but since I mostly use KDE these days I found this deep dive into how, exactly, network shares work in KDE quite interesting. It turns out that while network shares in KDE's Dolphin mostly work, it does involves a few layers that sometimes don't interact well with each other, leading to really curious and annoying problems with mounted shares not appearing, permission issues, and so on. The biggest cause of problems is when using a non-KDE application in KDE that also happens to use a non-KDE save/open dialog. Such a non-KDE save/open dialog won't be able to see any network shared mounted by KDE, and sadly, quite a few applications you're likely to use on a KDE installation use non-KDE open/save dialogs, like Blender, GIMP, LibreOffice, OnlyOffice, Inkscape, Audacity, DaVinci Resolve, and more. That's one hell of a list of applications to offer inconsistent or outright broken access to network shares you've set up and mounted in KDE. Luckily, this issue seems to be getting a ton of attention soon. All is not lost. Happily, KDE just received an investment of over €1.2 million from the Sovereign Tech Fund, and it includes funding for improvements to KDE's network share handling! ↫ Nate Graham The project is in the planning phases at the moment, but they're considering a whole slew of possible changes, fixes, and workarounds to make this stupid and annoying problem just go away. In 2026, nobody should be dealing with manually editing /etc/fstab or getting frustrated over supposedly disappearing network shares.

Xfce’s new Wayland compositor sees first alpha release

The developer working on Xfwl4, the Wayland compositor for Xfce, has published the new compositor's very first alpha release. Considering it's only been six months or so of work, it's impressive to see the effort reach this state already. The end goal of xfwl4 is to behave as closely as possible to an Xfce desktop running on an X server. Ideally a user could switch between the two without even knowing there's a difference. In reality, of course, it won't be quite that seamless, and there's still more work to be done to get as close as possible to that ideal. This is a first solid cut at it, at the very least. ↫ Brian Tarricone Being the very first alpha release, it won't surprise you there's a few things missing or broken at this point. Still, if you're brave, you can download and build the release and try it out.
