• I can publish anything, but...

  22 August 2014 ( #blog.com, #censor, #censorship, #HeadHunter, #job, #resume, #SuperJob, #Uncategorized )

  In my blog, I can post just anything on any topic, even criticise blog.com policy. Everyone can publish professional resume on superjob.ru. I did that, too. However censors at superjob.ru got anxious about my lack of recommendations and decided to correct...

• Outrunning Sage HNF subroutine

  24 March 2014 ( #Dixon lifting, #Hermite, #Hermite Normal Form, #HNF, #Stein, #Uncategorized, #W.Stein )

  I earlier announced that I intend to modify W.Stein double-determinant algorithm computing HNF. In case someone reads my blog, I report current state of the project. Re-implementation of the algorithm (benefiting from Dixon linear solver and other fast...

• Bionic on x86_64

  04 November 2015 ( #bionic, #Android, #x86, #x86_64, #amd64, #toolchain, #gcc )

  Google published a number of GCC toolchains targeting a number of platforms (including x86 and x86_64 Android), and claims that the toolchain is open-source, but forgot to publish compilation instructions. x86 Android toolchain exists since 2011. Toolchain...

• ppcg + CUDA

  27 February 2014 ( #automatic code transformation, #Cuda, #NVIDIA, #ppcg, #Python, #Python2, #Uncategorized )

  Answering the question 'where are ppcg C-to-CUDA transformation examples' myself. The answer is 950 lines in Python found in my git repository ppcg_polybench_test-benchmark. I discovered a way to automatically convert any piece of Polybench-C testsuite...

• blog.com oddities

  31 December 2013 ( #blog.com, #bug, #login, #password, #quirk, #Uncategorized )

  Here at blogger.com one can create good-looking web page with moderate effort. However there are some minor problems with the platform. I discuss them here to alert newbies. I also hope that blog.com team sees to it. 1) Blog.com silently cuts off password...

• Alyaska vote

  24 March 2014 ( #Alyaska, #Russia, #Uncategorized, #USA, #vote, #White House )

  Some person unable to write 4 sentences in English without big amount of mistakes placed a petition on US White House official site. Strange that the document was not rejected due to errors and unclear formulation. The petition calls for taking Alaska...

• MPIR is for Windoz, GMP is for Linux

  11 April 2014 ( #gmp, #Linux, #mpir, #Sage, #Uncategorized )

  Yesterday I wrote a post describing how I managed to convince Sage to use MPIR instead of GMP on my desktop. Today I deleted that post, to write this post instead. Probably everybody except me knows that MPIR is slower than GMP under Linux, and nobody...

• GMP tuning makes it slower

  12 April 2014 ( #benchmark, #gentoo, #gmp, #tuning, #Uncategorized )

  Switching from untuned to tuned installation of GMP 6.0.0a, I experience minor slowdown, instead of speed improvement. Acoording to profile_sswdlr.gmp6_untuned.cout, it takes 12136.43 seconds to count HNF of five different random matrix of size 3000 with...

• Blog.com, wordpress and $

  12 March 2014 ( #blog.com, #html, #Uncategorized, #wordpress )

  Wordpress supports latex formula, $ latex YOUR_FORMULAE $. For instance, this is R(n) with tilde above R: $ latex \tilde R(n) $ See nice formula for latex $\tilde R(n)$ above? No, you don't. I don't see it either. That's because blog.com disables some...

• Why your Gentoo Linux is slow

  12 April 2015 ( #Gentoo, #Haswell, #GMP, #mulx )

  Among many flavors of Linux, you chose Gentoo, because it is source-based. Which means software is compiled at your computer, and tuned the way you like (want this library but not that library; want this library with Python bindings and no documentation;...

• Welcome to 90's

  21 December 2014 ( #crisis, #panic, #Sberbank )

  Moscow commercial banks are short of euros and dollars, so their customers have problem withdrawing money. By the letter of the law, Tsentrobank has reasons to close down the banks, for failing to keep contracts. Yesterday Sberbank cash machines located...

• Russians are coming!

  17 March 2014 ( #Uncategorized )

  As we all know Uncle Sam has its own ways of spreading America-style democracy (methods include propaganda, cash spam, Microsoft software, field troop operations, bombarding enemy's capital with heavy weapon such as airplane bombs). Recently Mr Putin...

• blog.com, bye

  04 December 2014

  Since blog.com is nearly always down or does not allow me to log-in, I moved my blog here at over-blog.com. Automagically moving blog partially succeeded. Internal links are still pointing to qauqe.blog.com; level 2 pages are absent (for instance, my...

• I am alive and continue my research

  23 February 2015 ( #RAZIN, #software, #linear algebra, #determinant )

  Yesterday I noticed that my published software was not functional because I forgot to put online a .C source file. Lack of complaints and bug-reports, and low visits counter indicates that probably noone is using my library. Still I keep working on my...

• blog.com image policy

  29 December 2013 ( #Uncategorized )

  To my surprise terms of service do not ban nudity. They just allow the boss to delete whatever users publish. And it is not hard to find boobs on .blog.com, example here. Probably photos of naked female not engaged in sexual activity are allowed.
