- Address sanitizer is the king of checking memory leaks and other problems. It's been available on Linux for many years, and we have had it available in our Milo Code Database templates since a long time, too. Now, ASAN comes to Windows - although at the moment getting it to work is hard and it's availability is very limited. KDAB has a nice article outlining the steps necessary to enable ASAN on Windows.

- Felgo now has its own chapter in the Cadaques QML book. Read more...
- Qt 6 will come with really nice and powerful new asynchronous APIs extending existing QtConcurrent module (and others). A recent blog post provides all the details, with lots of example code - highly recommended reading! Read more...
- Qt 6 will come with a new signal-slot connection type: Qt::SingleShotConnection. Read more...
- QVariant in Qt 6 will not compare values from different types automatically. Read more...
- In Qt 6, QList, QString and QByteArray will have a subtle behavior change - any non-const method will invalidate previously acquired iterators. Read more...
- I think I mentioned it already last time, but Qt 6 will come with a new bindable property system (same as in QML - now available also in C++), and Lars has recently rewritten it to substantially improve it. A discussion ensued about compiler compatibility because as usual some embedded systems ship with unbelievably old compilers. Read more...
- Qt 6 alpha will come out soon (probably next week). Plans for Qt 5.15.2 are slowly gathering, but release team says getting Qt 6 done is a top priority for them
- QtProtobuf - a Qt wrapper for Google's Protobuf. Read more...

- Tesla has announced a new "tabless" battery which packs more punch while also being cheaper, read more... Honestly - the numbers do not look too impressive, with range getting only about 16% higher. For a big "battery day" I expected something more extraordinary
- And staying with Tesla - here's an interesting story (not new) about a guy who hacked Tesla and gained full access to the whole fleet of their vehicles (all vehicles manufactured by them). Read more...
- KDE's Plasma can run under Vulkan GPU drivers, read more.... It is only a tech preview and won't be widely available until Plasma 6 (which will come after Qt 6), so we will have to wait a few years to see it running in regular, stable Linux systems
- Google is pushing hard to get Android more compatible with the mainline Linux kernel. A milestone has been reached which allows kernel 5.9 to be used (with just a single patch) to boot Android AOSP (on some chips at least). Read more...
- If you use GitHub, there is now an officially released (no more beta status) command line client for GitHub. I have been using it for a few weeks now, it's gorgeous! Here is a small demo and here you can download it.
- OBS ninja is a peer-to-peer, anonymous video chat (no login required). Read more...
- NXTPAPER is an attempt to make e-ink but with LCDs. Interesting, but we'll need to wait for real-world tests to really know if it's good or not. Read more...
- There is a new class of speculative attacks on CPUs, called "BlindSide", read more.... Affected are both Intel and AMD processors
- NIST is preparing a new encryption standard which should work in future world where quantum computers invalidate all our current encryption. Read more...
- A new and better algorithm for graph crossing has been discovered. Read more...
Science & others
- Airbus has announced plans to develop aircraft running on hydrogen instead of jet fuel, read more.... For now, this is only a publicity stunt; they have no prototypes, and they plan to have them ready by 2035 ;-)
- Plastic cannot be efficiently recycled, read more... Let this sink in - even if you sort your waste and care about recycling - most of the plastic still lands in a landfill!
- Hubble took visible and infrared images of Jupiter (it does so every year), and they look gorgeous. Even the moon Europa got in the view of the first shot! Read more... and a wallpaper-worthy composite:
- Research suggests that objective reality does not exist. Read more...
- The speed with which ice cover is disappearing from the Earth matches our worst-case scenarios, unfortunately. Read more...
- There is some evidence (and not from humans ;-)) that regular, mild exercise helps protect the brain from stress. Read more...
- This isn't news, but is good to know: why electric cars are always green, even when recharged by coal-based power plants. Read more...
- Roman Space Telescope's mirror has been completed Read more... RST is similar to Hubble, but packs a 288 megapixel camera and 100 times larger field of view.
- Some objects in the sky might be transparent stars made of bosons - and not black holes. Read more...
- A compact and not too packed with maths summary of bayesian optimisation. Read more...
- It's been all in the news recently so you probably know already. But I have to repeat - phosphine has been found in the atmosphere of Venus and the most probable explanation is that there is some microbial life there. But, and it is a big BUT - it does not mean that there is life on Venus, we don't have any clear confirmation of that. Read more...
- It turns out colliding neutron stars produce only a small amount of gold, which is puzzling. So far it has been assumed that most gold in the universe comes from such collisions, but now we don't know anymore. Read more...
- Lattice containment fusion might bring us small sized nuclear fusion reactors. Read more...
