Percussive maintenance is really just short, fast, and localized instances of turning it off and on again.

3·2 days agoHow’d that work with licensing. Are they gonna open-source the nt kernel?
There is some more complexity. Melee jetpack jumping is still a thing, but with more skill, you need a sort of double jump that eats jetpack like nothing and takes reach, then land on a fitting slope to launch. You’ll loose height and it ends when you hit ground, so aiming this well under those conditions feels really good. The longer the jumps the more efficient.
There are also movement upgrades pairing with this you can select. Either just skipping it and going for run speed, or embracing it speccing into the jetpack.
This also makes sure things don’t feel slow anymore down the progression no matter the specifics.
yes, yes.
yes, I think so, no.
But I don’t think that’s all that important. Mlre importantly it feels more interesging now, and probably has a few cool new things you didn’t even know you wanted.
I found nms is pretty reliably getting less boring and anoying over time, though it’s still not perfect by any means.
Recently did an almost full playthrough for the first time.
I’d tried a few times over the years but this one stuck.

Technology@lemmy.world•Notepad++ updater installed malwareEnglish
5·10 days agoI cleaned it up. Your editor doesn’t like to nest formatting apparently. Using an editor that lets you write the markdown directly is probably better, and you are probably already familiar with markdown anyway, since it’s used all over the place.
2025-07-09 “Sometimes, when one door closes (lack of code signing) in life, another one opens (vulnerability).”

The sentence sumarizes well the situation in the previous version, 8.8.2.
There were - and still are - many false-positives reported in the previous version v8.8.2, by the antivirus software due to the absence of Windows code signing certificate.
How to install the root certificate:Double-click the certificate, it may tell you it’s invalid, ignore that and click: “Install Certificate…”.In the Certificate Import Wizard, select “Local Machine”, then click Next.If prompted by UAC (optional, depending on admin Previleges), click Yes.Choose “Place all certificates in the following store”, then browse and select “Trusted Root Certification Authorities”. Click Next.On the final page of the wizard, clickFinishto complete the installation.For detailed instructions, see Notepad++ User Manual.
We’re still trying to obtain a certificate issued by conventional Certificate Authorities, for a better user experience. But let’s be honest: it’s probably not happening. Notepad++ isn’t a business - it’s certainly not an enterprise - and apparently, that makes a popular open-source project invisible to their gatekeeping standards.
If the “gatekeepers” won’t issue a certificate under the name we deserve - so be it. At least it spares us from wasting time and energy on a frustrting process that demands we beg for a new certificate every 3 years. The Notepad++ Root Certificate may not carry their approval, but it leads us to freedom.
Edit (2025-12-03): Starting with v8.8.7, Notepad++ binaries - including the installer - are digitally signed using a legitimate certificate issued by GlobalSign. As a result, Installation of the Notepad++ root certificate is no longer required. We recommend that users who have previously installed the root certificate remove it.

Asklemmy@lemmy.ml•Why hasn't anyone tried making a combustion engine using fusion?
2·13 days agoNo idea why noone mentioned it, but this exists.
The core idea of combustion is using momentum to achieve combustion to generate back momentum (and heat).
The laser fusion detonation is similar, but I find other concepts reflect the idea way better.
General fusion uses liquid metal, that is compressed into the center trapping a bubble of fusion gas under extreme pressure for a moment. Inspired by cavitation bubbles in water that when symmetric enough can produce light and evaporate metal.
The fusion then bounces back onto the liquid metal, and fusion products are absorbed by it, so the heated liquid can be cycled into a heat engine. I don’t think there is an intention to recover mechanical energy though.Another approach is dynamic z-pinch. Helion would be an exanple.
You form a magnetic enclosure trapping fusion gasy then push the magnetic enclosure inwards, compressing the gas to fusion. The charged fusion products (needs fusion that doesn’t emit neutrons) are again trapped in the field, pushing against it with far more speed, effectively far higher temperature, causing the field to exoand again against the controlling magnetic coils, that now operate in reverse generating current from regeneratively breaking the push.I think this is the closest analogy to combustion engines. An initial push is inserted via momentum (of the magnetic field), which compresses the fuel, combusting it, increasing pressure/temperature, pushing back against the confinement which now absorbs the (magnetic) momentum, turning it back into power.
The only difference is that between cycles the power to keep the next cycle going is stored in capacitors not as momentum of something. And ofc the thing in motion is a more intangible magnetic field, together with currents running in magnets, not physical mass.

Asklemmy@lemmy.ml•How would one make a gravitational sensor, if possible, in space?
1·13 days agoHi, didn’t expect to see you here.
Let’s look at static differences first.
Absolute gravitational potential itself is impossible to measure, since all frames of reference act the same. But we can easily measure differences of potential using accurate clocks. This works well on the surface of earth in reference to outer space for example.
When measuring underground, we can also measure the accceleration along the path when walking there, since the acceleration is caused by the gradient in gravitational potential.
In practice though we would still use the clock method since we can measure time so much more accurately than acceleration.Going into orbit though, we get another problem, namely we are no longer “still”. The idea of gravity itself is a neat model, but it’s still general relativity underneath which means effects of our movement and of “gravity” are always mixed. So you can put a clock in orbit, but have to very accurately know the exact orbit to make an absolute measurement.
In effect the gps satellites have done this, and we can see their rate of time and attribute it to their orbit vs. their location, often written special vs general relativistic effects.
This value is not very useful, since not only do we average over the entire orbit, we also don’t know the orbit precisely enough.We can do better though, good enough to measure changes over time.
By building an even better optimized “clock”.
Regular clocks act kinda like gears. We have a mechanism that oscillates at a very stable high frequency, and then “gear” a mechanism to match it, but at a lower frequency, until we get to something we can measure with regular electronics. At that point, we get averages of many oscillations. We then have to send them on to a different clock, since we have nothing to measure our ticks against, for us they are evenly spaced. That receiver has to catch the very high bandwidth signal of billions of clock ticks, and compare it to a second clock.
Any anomaly of the signal path will look like a shift in time, a change in gravitational potential difference of the two clocks. Worse, atomic clocks are designed mainly for long-term accuracy, so they tend to have shifts in rates over shorter timeframes. Thus, instead we strip stuff to the bare minimum, and do our own clock with blackjack and hookers and without the whole clock part where it measured time.Einstein had a few Gedankenexperiments that still show up in lessons on relativity because they are good. One common object is a laser clock. You bounce a laser between plates, and the rate of bouncing changes according to the local rate of time. This turns out to make a pretty shitty clock, but lets you do optics on the output making for a really good comparison between two different clocks, via interferometry.
Since you need to measure two locations anyway to get the time difference, you can send out two beams of the same source, thus matching exactly, and align them on the return, making their path lengths precisely equal. On average.
If you do this well enough, you can see temporary changes to this, as fast as you can measure the beam interferences, since those beams are in effect comparing at extremely high frequency.You can now dump this instrument in orbit, and measure the changes along the orbital path, forming a high detail map of earths gravitational differences from the ideal. Or you can put it on earths surface or in outer space and wait for abrupt changes of gravity bumping into you.
Because ofc moving masses “update” the gravitational potential field, and if those updates happen quickly enough we can measure the change with our very precise change detector differential clocks, while the absolute difference might be too small to see on regular clocks, or affect all clocks equally due to great distance of the source, or the subsequent waves may cancel the change, averaging to 0.
Or would it not be possible because the sensor itself would interfere with the readings?
For one all the setups we have so far want to be extremely still, a single piece at rest. Not to prevent gravitational waves or even permanent changes in potential, but to prevent mechanical vibrations.
The equipemnt is extremely light as gravitational masses go though. When you go up in scale, mass changds with volume, with the cube, but strength of gravity, of the gradient, with the square of distance. So when comparing a small interferometer sitting on a 1m satellite, its effects are a million times weaker than earth, with a diameter on the order of millions of meters. Actually far less, since the satellite isn’t a solid ball of dense material.If you wanted to you could probably spin up a large barbell shape in space right next to a gravitational wave detector and not annoy the scientists from vibrations but from the waves. Probably. Take care it’s in shadow, otherwise the changes in light reflection onto the satellite would probably overshaddow your waves.

Linux@programming.dev•Linux Kernel 6.19 Will Introduce the Terminus 10x18 Console Bitmap Font
4·13 days agoI use an encrypted rootfs without “an initramfs”. Just requires some advanced fuckery.
A little known fun fact is that almost all kernels have a tiny stub-initram built into the kernel file. This is added when initram support is enabled, and is loaded before dedicated files are. It is however possible to supply your own initram directory or archive during kernel build to replace this built-in initram, so you can bake it in without leaving a separate file. No juggling with partitions, no boot options. Works just like a normal kernel “without initram”, since even kernels without one usually do have that stub one anyway.
The downside is that a) you have to build the kernel, and b) the files to pack have to be available when the kernel is built, meaning you can’t pack in modules of the kernel. But when building your own kernel anyway you can simply set the needed modules for encryption built-in and only pack the userspace cryptsetup executable needed for decryption, that way you get it all in a single kernel build, and the output is a single uniform kernel binary capable of decrypting your boot drive. No flags, no extra files, no access to the esp needed.
(I use gentoo with encrypted root btw.)

12·13 days agoFound the Gentoo user
That would make it a different problem than what I saw. Either your compositor has bugs not present in its xwayland, or firefox has bugs in its wayland implementation that don’t occur under x11. Seeing this is snap, that could also be causing the issue.
concerns me since I know distros are starting to default to Wayland
xwayland will be supported for a long time to come, so this would only affect users that don’t know about this “fix” yet. You should be able to use firefox in x11 mode until this is fixed.
It would be good if you could check if this happens with a native (non-snap) firefox installation running on wayland. Ideally also if you could try it in a different dwm, probably kde since you are presumably using ubuntu with gnome.
