Java with its copying GC deals fine with fragmentation albeit at the cost of more upfront memory. And even in Rust one can change the allocator to try to deal with fragmentation. But with Go there is simply no good options besides the rewri

In his last book “The Dawn of Everything” David Graeber very convincingly argued that the idea of modern democracy came from Indian tribes in Northern America. And it is also interesting how easily European countries went back to authoritar

For me the main advantage of Go over Rust is compilation speed. Then compared with Go Rust still rely on many C and C++ libraries making it problematic to cross-compile or generate reproducible builds or static binaries. The minus side of G

The only real advantage of European settlers was smallpox immunity. If not for that the history could move in a very different direction.

On my 2 years old ThinkPad laptop SSD is faster than lz4. On a fat EC2 server lz4 is faster. So one really has to test a particular config.

If Ukraine had access to Tomahawks, Russian oil industry would not exist at this point. With drones after two and halve years of attacks with multiple hits at the same refineries Ukraine reduced Russian fuel production at best by 20%. Flami

Yep, apparently Ukraine still cannot affect fuel production in Russia to any significant point. Drones with less than 100 kg of explosives do not do particularly significant damage. One really need to deliver like a ton or more of explosive

Ukraine was not able to interrupt production of gasoline and diesel in Russia in a significant way after two years of targeting oil refineries. Then attacks on pipelines and their pumping stations were not effective either as Russia was abl

lvm only supports checksums for metadata. It does not checksum the data itself. For checksums with arbitrary filesystems one can have dm-integrity device rather than LVM. But the performance suffer due to separated journal writes by the dev

What are the alternatives to btrfs? At 12 TB data checksums are a must unless the data tolerate bit-rot. And if one wants to stick with the official kernel without out-of-tree modules, btrfs is the only choice.

Nuclear is not that steady. Nuclear plants require a lot of water to cool things. And when a particular hot summer happens, rivers dry out and nuclear reactors have to scale down the power production or even be shutdown. And then they requ

Shahed shape is dictated by the need to sustain very high G and aerodynamic forces during the launch from a truck which in turn allows for a very fast deployment. Anything more aerodynamic will imply stronger, more expensive frame and less

The latest APKWS is IR guided and works in fire and forget mode that works nicely from the ground. And then drone interceptor struggles with Russians Shaheds with jet engines. On the other hand the latest development with drone interceptors

APKWS launching from air is a stop-gap measure in any case. The detection range for Shahed-type drones is tenths of kilometers, not hundreds, like with fighter jets or big missiles. One cannot have that many fighter jets in the air all the

Ukraine tried to come up with drones that can fly over 1000 miles. But drones the size of Shaheds just cannot fly that distance without significantly reducing the warhead. To attack things beyond that range Ukraine have used essentially Ces

APKWS interceptor is about 35K USD and works much better than drone-based interceptors. The problem is to scale the production, training and deployment. Another problem is detection. One needs wast multilayered system that US military misse

With Bayraktar it was a software update for radar that allowed for Russian to destroy them. The radar signature of Bayraktar was way off from a typical target that radars were looking for at the beginning of the war.

It is vastly more complicated to find targets at 1500 miles than at 20. So drones are effective at destroying big stationary civilian infrastructure and much less at long distance strikes at military targets. Russia's inability to dest

Toyota hybrids are very reliable and probably the reason taxi drivers around Europe prefer those. And with the proper PHEV the wear is even less.
