This is in relation to their TPCH benchmark which can be due to a variety of reasons. My guess would be that they can generate stencils for whole operators which can be transformed into more efficient code at stencil generation time while L

TPDE is a framework for writing a back-end for various SSA IRs. TPDE-LLVM is an LLVM back-end written using TPDE, but TPDE itself is independent of LLVM. The paper also mentions back-ends written for Cranelift's IR and Umbra IR usi

> All the money in the world won't change the fact that Source is an outdated pile of garbage. Given that the engine has been in, essentially, maintenance mode for almost a decade now, that is not really surprising. A more apt compa

The author striked out the part about CedarDB not being available -- which is true -- but Umbra is available as a docker container[1] for some time now. The "Umbra paper" linked also contains an artifact[2] with a copy of Umbra as

One thing I noticed though is that when autocompleting C++ statements like if or while it will add only the opening curly braces which is a bit annoying but makes sense. But it also sometimes adds them @_@

though I believe in RISC-V‘s case what will happen is that every vendor will have that realization at the same time, not tell anyone and make an extension and now there‘s five different incompatible encodings for the same operation.

The bin packing will probably make it slower though, especially in the bool case since it will create dependency chains. For bools on x64, I don‘t think there‘s a better way than first having to get them in a register, shift them and then O

Maybe people don‘t because they see, for example, Valve (a billion dollar company) struggling to get GNOME to implement drm-leasing for VR headsets. IIRC they‘ve been at it for multiple years, too. Or maybe it‘s because the compositor devel

> exotic things like take a screenshot I'm not sure but is this meant ironically? Because taking a screenshot is a thing people do very often. Capturing your screen is, too. Even by third-party programs. And yet they never put it in

That‘s a very nice writeup, I like the style. The mix of text to illustrations/memes was really pleasent. I have my reservations about the RISC/CISC nomenclature but I guess that‘s „each to their own“ >.> As someone who has

How so? The bootloader already runs in long mode with UEFI and it also takes care of bringing up other cores so this is not really a problem in my experience.

That reminds me of a somewhat funny story. I was listening to a presentation about a startup with about 10 people as you mentioned doing hospital digitalization (gist of it seemed to be sending patient data from one doctor to another). They

CERN at least seems to be using a solution that is running over Ethernet[1] but with custom hardware that is probably fairly expensive. They use a single time source and then measure the delay between each switch/node. Though, this is

Depends on the university - and course. I‘m currently at TUM (CS) and you don‘t need to submit any homework assignments to be admitted to an exam. Though there are some courses where part of or the complete grade are made up of homework ass
