Qt news
- Microsoft posted an informative piece on how they used consteval from C++20 to prevent a whole class of bugs from happening in their compiler.
- QBS 1.21 has been released, with an impressive wealth of features and fixes!. Good to see that this project is not dying!
- Delayed, but Qt 6.3 Alpha version is out with many new goodies. QML TreeView is now an integrated component.
- Qt Company is also releasing the new Qt Quick Compiler: this will compile parts of QML code into C++ and can give up to 30% performance gain in application startup and at runtime. For now, this is all only a Tech Preview, with a bit more stuff visible to commercial license holders. But it will be released together with Open Source Qt 6.3, too.
- QML extension for Visual Studio Code.
IT news
- New dangerous threat - SysJoker.
- If you feel like building your own keyboard, this might help: Adafruit KB2040 board.
- Linux kernel is getting a huge - HUGE - set of patches which optimize the headers and can speed up kernel compilation times by 88%!
- GauGAN v2 API from nVidia can change you into a real artist.
- Quite OK Image (QOI) Format - I love this! And image format which is super-fast in encode and decode operations while being roughly on-par with PNG when it comes to compression.
- In a new piece of research, scientists have shown a way to reduce the number of transistors in CPUs by up to 85%!
- CANBus (and other) extension to Raspberry Pi Pico.
Science and others news
- The biggest news for sure is the launch of JWST. The new, huge space telescope has launched successfully and is now also mostly deployed. The launch was so precise that the telescope will have enough fuel for 10+ years of service (maybe even 20!). So what's happening with it NOW? Its mirrors are aligning (which will take weeks) and the whole device is still flying towards its final position (L2 point).
- You can now cook toasts with graphene.
- Somewhat weird, but proven to be effective, way to lower stress and to stop panic attacks.
- We might have seen hints of gravitational wave background - since almost anything that happens in space is producing small and large gravitational waves, it is certain there is a general background "noise" of them. Now we have seen some first evidence for it.
- LHC continues seeing hints of a new, fifth force of nature.
- This article goes into super detail of how the Earth, Sun, Milky Way etc. are moving in space.
- Matter and antimatter behave in the same way under gravity. No surprise there, but at least now we know for sure.
- TESS has discovered another star which has dramatic and weird changes in its brightness.
- We have observed a star while it was close to exploding and then monitored it while it was going supernova. This is important because we usually only notice supernovae after they explode.
- You may remember a weird, house-like object observed by Chinese moon rover a while back. Well, the rover took a detour from its intended path to study it. No scientist and all news outlets were surprised to find that it was in the end: a piece of rock. On the Moon. What a shocker. Anyway, here's an article in Chinese, but the images should be enough.
- There is a new, effective, and cheap vaccine for COVID, which might finally bring the healthy goodness to poor countries.
- A fresh container with moon rocks is going to be opened after 50 years!
- Scientists have invented a new composite material which shields against radiation (so something like lead but it is not toxic!).
- Parker Solar Probe has flown through suns atmosphere.
