Embedded C. # # Tone generation from: [link] # # 29-Apr-2019 Brendan Gregg Created this. This is the culmination of five years of work: the BPF kernel runtime, C support, LLVM and Clang support, the BCC front-end, and finally the bpftrace language. This is not my best code, since I hacked it in a hurry, but here it is: #!/usr/bin/python

This can be changed later using the pg_checksums utility, but that will be a painful exercise on a big database. cat /usr/lib/systemd/system/postgresql-14.service. That is where all “ALTER SYSTEM SET/RESET” commands keep the information. But another database might be an OLAP system. Type "help" for help.

The Morning Paper

DECEMBER 8, 2019

At the start of November I was privileged to attend HPTS (the High Performance Transaction Systems) conference in Asilomar. On the last morning of the conference Daniel Bittman presented some of the work being done in the context of the Twizzler OS project to explore new programming models for NVM. The Twizzler programming model.

This ruling in itself raises many questions: how much creativity is needed, and is that the same kind of creativity that an artist exercises with a paintbrush? Tracing provenance with these more complex systems will be difficult—but with RAG, we now have the tools to do it. We have provenance.

Some of these are exercised by the “wrong order” permutations above, but even call sites that remember the right argument order can make mistakes about the actual values. But if the sight of these function signatures has had you pulling your hair and shouting “use the type system, Luke!” Consider using a class instead. is_reachable?

Werner Vogels weblog on building scalable and robust distributed systems. We believe that making these GPU resources available for everyone to use at low cost will drive new innovation in the application of highly parallel programming models. All Things Distributed.

At the lowest level, all computers are programmed with strings of ones and zeroes. When you program in machine language, you are controlling the computer at its brainstem, the root of its existence. So a whole Babel of computer languages has been created for programmers: FORTRAN, BASIC, COBOL, LISP, Pascal, C, PROLOG, FORTH.

There was no deep goal — just a desire to see the maximum GFLOPS in action. The exercise seemed simple enough — just fix one item in the Colfax code and we should be finished. After this, the micro-ops will wait in the Reorder Buffer until they can be retired in program order. Instead, we found puzzle after puzzle.
