Clang fatal error: standard headers not found

In the morning I decided to try building the json11 library. I almost submitted a github issue but then understood that the error quite silly and was probably originating from my broken setup:

$ make test
clang++ -O -std=c++11 -stdlib=libc++ json11.cpp test.cpp -o test -fno-rtti -fno-exceptions
In file included from json11.cpp:22:
./json11.hpp:53:10: fatal error: 'string' file not found
#include <string>
1 error generated.
test.cpp:1:10: fatal error: 'string' file not found
#include <string>
1 error generated.

As you might see, string is a part of the standard library.

Let …

Deploying sample Silex app to Heroku

For the last couple of weeks I met quite a few people who were praising PHP and I had an idea to have a brief look at it once again after more than 4-year break.

I decided to push a sample application to Heroku by following their tutorial but that turned out to be nontrivial on my Ubuntu 14.04LTS. Below I’ll give a brief list of commands that I needed in addition to those provided by Heroku to get the app running locally before pushing it to Heroku.

Initially, we start by naviagiting to the repository and following …

Using EOSInfo utility to get your Canon EOS information

You can use these tools to get the information for your old Canon camera. Per platform:

I haven’t found a similar tool for Linux, but you might still be happy to find out that you can [run Linux]( on newer camera versions that have an ARM onboard!

Learning GNU screen

I recently started to remotely log into several servers quite often so I felt a need to maintain reliable connections to them and I considered a few choices:

As the beginner, I decided to stick to the easiest option - screen. It comes preinstalled on many server and many administrators install them alongside vim, emacs and git.

I decided to use this blog post for two purposes: to collect the most helpful links to learn screen; and to plan for deeper explorations in future (in this case, Mosh and Tmux).

Useful screen resources

Moving Google Drive folder

UPD: My approach was partly successful, because Google Drive still decided to resync all my files after I successfully moved the root folder. If you have any idea what I could’ve missed, you’re welcome to leave a comment below.

Let’s describe what we aim to do: we have Google Drive on our computer in a synced state, but we want to move the whole Google Drive folder to another path (or in case of Windows, most probably - another disk).

All actions described below were performed on Google Drive for Windows (App version: 1.15.6464.0228). Windows …

Small plans for January

This is a great year, I hope! So in order to make it great, we need to put some efforts to make it bright.

To strive, to seek, to find, and not to yield
- Alfred Tennyson

I have few resolutions for the new year, but nothing earth-shaking:

  • healthy rythm
  • productive workflow
  • more books, less talks
  • less artificial, more real (people, meal, entertainment)
  • only grow, always move forward

In order to achieve these ambitious goals (I think you shalln’t be deceived by their simplicity), I need to reach some goals:

  • migrate to Ubuntu successfully (especially solve dependency on those small …

Creating shortcut function in Fabric to create a Pelican draft

I migrated from Wordpress to Pelican few month ago and so far I was satisfied with it, mainly because my demands to the blogging platform are far lower than one might imagine. But as atrue engineer, I always strive to eliminate any duplication in code or in actions.

For this reason I’ve created one more Fabric function that creates a draft for me, properly setting the date and slug for me:

drafts_path = 'content/drafts/'

def draft(title):
    from datetime import date
    from time import strftime, gmtime
    from unidecode import unidecode
    import re
    from subprocess import call

    today_iso = …

Pelican on Windows

I enjoy using pelican so for so much. However, few issues hit my mind recently:

  • Medium is such a nice place to write that I can merely resist my temptation;
  • There is no ability to run person search across the static website;
  • I’m tied to UNIX environment in order to run the Pelican development server for preview.

I recalled a great quote:

Once you say you’re going to settle for second, that’s what happens to you in life.

—John F. Kennedy

So I decided to see if it’s possible to resolve all of that issues for …

Rename all *.rst files in a directory according to their date


  • add verbose mode
  • move awk output into variable and test if file already begins with a date
for f in $(find ./content/ -name '*.rst'); do
    name=$(basename "$f")
    dd=$(dirname "$f")
    d="$dd/$(cat "$f" | grep ':date:' | awk '{print $2}')-$name"
    if [ ! -f "$d" ]; then
        mv "$f" "$d"
        echo "File '$d' already exists! Skiped '$f'"
