USB 3.0 cable tip

Did you know, that using cheap USB 3.0 cables could decrease performance dramatically? Lets compare Samsung EVO 850 M.2 inside Transcend CM80:

Don't try to save money on cables. Buy something good and reasonably priced, like Anker.

Double Commander

Double Commander doesn't look as bad as at first glance if you configure it properly! Looks modern, right?

And it's still the best file manager in Linux. Tuning and configuration possibilities are endless. If you invest some time learning non-always-obvious configuration, you can make it work exactly as you want. Sweet.

Run Fish Shell command from any app

I've implemented little script that allows to call Fish Shell prompt from any app. Very handy for running single commands from Double Commander or Sublime Text:

  • Prompts for single Fish command in left bottom corner of given application window
  • To make benefit of Fish shell autocompletion and history
  • Closes after one command is executed
  • If command fails, leaves window to inspect error message

See this animated gif for example.

For example you want execute git clone [email protected]:dmi3/bin.git in current directory from Double Commander:

  1. Press Shift+F2 and terminal window appears in left bottom corner of Double Commander window
  2. First you want git and clone to be autocompleted using Fish
  3. During clone process you want to see git command output to monitor progress
  4. If everything is ok, prompt will close
  5. In case of error you will have chance to read error message

Nonitrusive User Tracking Tip

What if you want to know a little about your website visitors, without full-on creepy surveillance and 1, JavaScript controlled by the third party? Or don't have JavaScript on the page at all? Just you know, to be aware if anybody is reading your blog at all.

I don't want to track every your mouse movement or know browser or resolution. Just visitor page views, please.

So almost every Web Analytics (except Google Analytics, of course) - Clicky, Yandex.Metrica or StatCounter, have an alternative image in <noscript> to track rare visitors without JavaScript enabled.

Put this image, somewhere in your template, and you will still get insights!

By the way, why does everybody need to bring tons of code to show little share button? Whats wrong with old good <a href=...?

Crash Bandicoot

Sony PlayStation 4 players

Did you know that first Sony PlayStation had an accessory called multimap that allowed to play split screen for 4 players? I knew, but neither I or my friends were never able to get this accessory :(

But there still a chance to play Crash Bandicoot with 4 friends, as Mednafen emulator supports it!

Breaking News Tip

Very busy, but still want to get notified about really important news like Meltdown or Heartbleed?

Just query 3 lastest topics from Hacker News, with rating > 1000. You can format it nicely using jq, and add it as greeting message for your shell, using this simple script ↓

Source on Github

The major difference from weekly newsletters is it that newsletters need to fill up content to 10 topics, even if nothing happened. 1000 point threshold saves you from clutter, and you will not be bothered if nothing happened. "No news is good news".

Some alternatives:

  • Check News API for more sources
  • Ubuntu motd was initially meant to do that, but...
  • If you are not busy at all, check newsbeuter - awesome CLI RSS client

Markdown Tip

       _____                                           ._.
      /  _  \__  _  __ ____   __________   _____   ____| |
     /  /_\  \ \/ \/ // __ \ /  ___/  _ \ /     \_/ __ \ |

            \/            \/     \/            \/     \/\/

Remember WordArt? Miss these cool creative headers in the modern world, where all sane people write their documents in Markdown? Pro tip, you can achieve same expressiveness by using FIGlets!

You can generate it online, commandline or even find plugin for your favorite text editor!

Don't forget to indent it with 4 spaces, to preserve monospaced font when compiling to html.

Clipboard Manager Tip

Don't underestimate how useful Clipboard Managers, and especially Clipboard Manager Actions could be. It allow you to link applications not connectible by other ways. For example by hotkey:

  • Url copied from Vivaldi (Chrome) → Script that queues download to Synology NAS
  • Url copied from Chrome → Play video stream in Vlc (without complicated hacks)
  • Add bookmark
  • Save to Instapaper
  • Show QR code to quckly transfer copied text to your mobile phone
    • qrencode %s -s 15 -o /tmp/qr.png && xdg-open /tmp/qr.png
  • ...

Taking and Editing screenshots on Linux

Best Tool For taking screenshots in Linux Ubuntu

Windows and Mac users have Lightshot - simple tool that allows you to take, caption and edit screenshot in seconds. Unfortunately, on Linux we either stick with command line tools like scrot. Or use Shutter, which if you ask me is terrible: app starts too slow, editing requires multiple clicks, there multiple windows...

Theres awesome screenshot tool called Deepin Scrot. It have Lightshot-like intuitive interface, that allows select windows or area, and edit screenshots instantly.

Theres bug, when screenshot included selection frame. Until its merged you can use fix in my fork:

Better Notify OSD Alternative

Notification OSD Alternative Ubuntu's Notify OSD was great idea, most of functionality unfortunately wasn't implemented. It seems will never be completed.

If you are still using Notify OSD it that and replace with with Dunst.

Dunst advantages over Notify OSD:

  • Can show more than one message ⚠
  • Minimalistic
  • Highly configurable
  • Message stacking
  • Group duplicated messages
  • Close messages on click
  • Notifications with critical urgency (notify-send -u critical test), don't dissapear automaticaly and will be only closed on click
  • idle_timeout so you don't miss notification if you are not near computer
  • Custom rules for certain applications
  • History
  • Supports urls
  • Works fine in multiple monitor configuration

See sample config.
