Shirish Agarwal: A tale of unfortunate coincidences and incidents

Filed under

Linux
Debian

I went back to the vendor with my old stock SMPS and it worked but found that grub2 menu was missing. It was just plain booting to windows 10. I started a thread at debian-user trying to figure out if there was some issue at my end, maybe some grub variable had got lost or something but the responses seemed to suggest that something else had happened. I also read through some of the UEFI documentation on wikipedia and web, I didn’t go to much depth as that would have been distracting as the specification itself is evolving and is subject to change. I did find some interesting bits and pieces but that is for a later date perhaps. One of the things I remembered from my previous run-ins with grub2 issues is that supergrub2 had been immensely useful. Sadly though, the version which I tried as stable was dumping me to grub rescue instead of the grub menu when I used the ISO image on a thumb drive. I could have tried to make a go for it but was too lazy. On an off-chance I looked at supergrub2 support and did find that somebody else also have had the same exact issue and it was reported. I chimed in and tried one of the beta versions and it worked which made me breathe easier. After getting into debian, I tried the old $ sudo update-grub which usually fixed the issues. I again tried to boot without using the help of the usb disk but failed as it again booted me into MS-Windows environment.

A Look At The GCC Compiler Tuning Performance Impact For Intel Ice Lake

For those wondering if it's worthwhile for performance recompiling your key Linux binaries with the microarchitecture instruction set extensions and tuning for Ice Lake, here are some GCC compiler benchmarks looking at that impact for the Core i7 1065G7 on the Dell XPS 7390. In particular, this article is looking at the affect on generated benchmark binaries when built under the following CFLAGS/CXXFLAGS configurations: -O3 -march=skylake - Just optimizing for conventional Skylake processors. -O3 -march=skylake-avx512 - Optimizing for Skylake AVX-512 processors like Skylake-SP/Skylake-X. The Skylake AVX-512 enables use of the AVX512F, CLWB, AVX512VL, AVX512BW, AVX512DQ and AVX512CD instructions. -O3 -march=icelake-client - Optimizing for Icelake client/desktop processors. New instructions exposed here not found with Skylake/Skylake-AVX512 include AVX512VBMI, AVX512IFMA, SHA, CLWB, UMIP, RDPID, GFNI, AVX512VBMI2, AVX512VPOPCNTDQ, AVX512BITALG, AVX512VNNI, VPCLMULQDQ, and VAES. Note there is also the "icelake-server" target for future Ice Lake Xeon Scalable processors where additionally PCONFIG and WBNOINVD are flipped on. Read more

PHP 7.4 Performance Benchmarks Show A Nice Improvement - But PHP 8.0-dev Is Running Even Faster

PHP 7.4 is due to be released next week as the annual major iteration to PHP7. Like we have seen through the PHP7 releases, while new features continue to be tacked on for this popular web-based programming language the performance has continued evolving. Here are the latest benchmarks of PHP 5.6 through PHP 7.4 while also looking at the PHP 8.0-dev performance that is in development on Git master. Outside of the performance realm, PHP 7.4 is another exciting update thanks to finally introducing FFI support. The Foreign Function Interface for PHP allows accessing C structs/functions/variables from native PHP code for making it easier to interact with C libraries from PHP. In addition to the headlining FFI support of PHP 7.4, this next release has a preload function to preload functions/classes to speed-up the loading of scripts by 30~50%, language alterations, TLS 1.3 support in PHP OpenSSL streams, and a variety of other smaller additions.
