  • Opera Neon

    Funny browser: mouse multitouch, gestures, extensions, settings import, vpn, turbo, profile login – that’s all does not work. No Linux version. But tab management is really neat! Strange things: there are 3 search engines pre-configured: google, Yandes and mail.ru. I am not located in the Russia though!

  • Google group calendars in Evolution Mail

    If your organization uses Google Apps as mail service but you are using Evolution, there is no evident way to view and edit shared group calendars until recent versions. To add group calendar you need: go to calendar settings on web Calendar Address: -> ID (somenting like example.com_1d32345331343234213832@resource.calendar.google.com) Evolution -> New Calendar -> Google User name -> this ID Auth with usual name-pass…

  • DKIM=temperror

    Recently I have checked my messages headers of the mail that comes from the andreybondarenko.com MX and found that Google shows that my DKIM signature is invalid: In the spam score section: However the header itself is present: I have found that it’s quite common configuration error of the OpenDKIM, the selector you choose to store key can be chosen randomly, but the TXT record should match /etc/opendkim.conf.…

  • Puppet vs Ansible vs Chef vs Salt

  • Let’s encrypt cert updates

    Let’s encrypt is wonderful, but certificate are getting expired every 3 months. Since it’s a first time I need to renew them, I have done it manually. The tool authenticates you (by default) with special file created in the .well-know/acme-challenge directory of the root, so the blog engine should not interfere or rewrite anything and should not return it’s own 404 page. Historically my nginx.conf has lots of existing redirects and rules,…

  • Moving iTunes Account to the other country

    If you are changing the country you may need to change the location of your online services as well. May be if you are moving from US to EU it’s not that important, but if you are moving from Russia to EU keeping old setting would be painful. First, payment can be only done from Russian card. Second, by Russian regulations “Russian” users’ data must…

  • Google Analytics and visitors’ language

    Vote for Trump, epta!

  • TOC and collapsible block samples

    I am writing some tool for my daily work that produces fancy HTML page from RHEL, CentOS or Fedora log and config files, so it would be more easy to read them. Nothing special, just some bash scripts with sed, grep and awk that produce HTML with some CSS and JQuery. TOC I really liked: http://projects.jga.me/toc/ It’s very easy to use and implement, it just…
