Programming/Development: Math Libraries for Python, Compiler Fuzzing With Prog-Fuzz, Intel MKL and Flutter

• 10 Best Math Libraries for Python

  Many times, when you write programs you need to use special functions that others have used before you. When this happens, open source comes to the rescue and gives you a library that covers that need. Python calls theirs modules, to use modules you need to import them.Modules for mathematics are especially useful when you have the theory ready but need to use standard math for your particular problem.  The Mathematics module in the Python standard library has many features. It is useful to check if you can solve your problem easily with these functions. If you need to know what functions exist you need to go through the list. However, first realize that the module implements all the C standard functions. The simplest use of Python for math is as a calculator. To do this, start Python on the terminal and use the print function.

• Compiler Fuzzing With Prog-Fuzz Is Turning Up Bugs In GCC, Clang

  Vegard Nossum of Oracle has been working on fuzzing different open-source compilers for turning up bugs within these code compiler likes GCC and Clang. Vegard ended up writing a new compiler fuzzer from scratch making use of AFL instrumentation. This new fuzzer is dubbed simply Prog-Fuzz and is available on GitHub.

• Intel MKL in Debian / Ubuntu follow-up

  About two months ago, in the most recent post in the series, #18, we provided a short tutorial about how to add the Intel Math Kernel Library to a Debian or Ubuntu system thanks to the wonderful apt tool -- and the prepackaged binaries by Intel. This made for a simple, reproducible, scriptable, and even reversible (!!) solution---which a few people seem to have appreciated. Good.

• Meet TLBleed: A crypto-key-leaking CPU attack that Intel reckons we shouldn't worry about

  Intel has, for now, no plans to specifically address a side-channel vulnerability in its processors that can be potentially exploited by malware to extract encryption keys and other sensitive info from applications. A team of researchers at the Systems and Network Security Group at Vrije Universiteit Amsterdam, in the Netherlands, say they were able to leverage the security weakness to extract crypto keys from another running program in 99.8 of tests on an Intel Skylake Core i7-6700K desktop CPU; 98.2 percent of tests on an Intel Broadwell Xeon E5-2620 v4 server CPU; and 99.8 per cent of tests on a Coffeelake part.
