There is a problem that involves Javascript and regular expressions. The JS implementation of regexp does not support Unicode properly, for example /\b\S+\b/g regular expression will not count words with Unicode characters of many national alphabets and scripts, such as Cyrillic, Greek and Hindi. Unfortunately \S is restricted to Latin-only characters of English alphabet. To solve this problem we must explicitly include all Unicode characters. My solution is to use /([\u0080-\uFFFF\w]\u0027?)+/g regular expression instead. It covers the wide range of Unicode characters (from 0080 to FFFF) that includes all national alphabets + apostrophe symbol (0027). This regex has been tested with the following sample text and it counts all 55 words accurately, ignoring all special characters and punctuation, I used https://regexr.com to test it with this sample text that includes words from several alphabets.

Switching between two (or more) keyboard layouts in Openbox DE is a task that's quite easy to accomplish, although it might not be so obvious as in other desktop environments. This solution was tested on Arch Linux. You just need to edit this file (assuming you want to switch between English and Ukrainian Phonetic layouts with Alt-Shift): /etc/X11/xorg.conf.d/01-keyboard-layout.conf Section "InputClass" Identifier "keyboard-layout" Driver "evdev" MatchIsKeyboard "yes" Option "XkbLayout" "us,ua(phonetic)" Option "XkbModel" "pc105" Option "XkbOptions" "grp:alt_shift_toggle" EndSection If you have Nvidia card, don't forget to edit /etc/X11/xorg.conf.d/20-nvidia.conf and change Driver from "kbd" to "evdev" in InputDevice section: Section "InputDevice" Identifier "Keyboard0" Driver "evdev" EndSection Y

When you use Applitools for testing, it is important to keep all pages in the same state as they used to be when the baseline Applitools screenshot was taken. In Applitools visual difference means a bug. This is why a blinking caret (cursor) can become a problem when the baseline screenshot was taken with a caret either visible or invisible, as long as the actual screenshot was captured with a different state of the caret. We can avoid this issue if we hide the caret by making it transparent before taking a screenshot in Applitools. This is how we can do it in Selenium Webdriver (Javascript bindings) (assuming that you initialized the driver object with Webdriver).

If you are already using SauceLabs for automated web UI testing on mobile devices, then you could be interested in trying TestObject cloud service that was acquired and became a part of SauceLabs family in 2017. It allows you to run your existing tests on real devices (Android and iPhone). SauceLabs provides emulators, which work quite well, but, depending on the requirements of your project, you may need to execute tests on real hardware. Another reason for switching to TestObject could be using the latest version of Android OS which may not be available at SauceLabs. At the moment of posting this article the latest supported version was Android 7.1 on SauceLabs and Android 8.1 on TestObject. Luckily the transition to TestObject is quite seamless. You don't need to modify your existing automated tests, only the provider endpoint and a few capabilities. The disanvantage of using a free Testobject account is that you are limited to only a few devices which are marked as Free in th

SauceLabs does not annotate jobs by default, showing the question marks instead of statuses, and the name of a job is always set to "Unnamed job". Luckily we have all the powers of Sauce Labs REST API in our hands and can both set the name of a job and its final status to something more meaningful. This example demonstrates how it can be done in Node JS. Every Sauce Labs job has a unique ID. We get this ID from the Webdriver object. saucelabs.js main.js

I'm assuming you already created your project on Gitlab and got your personal access token . This is a simple synchronous function that reads a Gitlab pipeline variable in NodeJS using Gitlab REST API v3. It uses sync-request that is not recommended to use in a production environment, although it can be successfully used in automated testing and various scripts.

One-liner for increasing sound volume for recorded files on Linux (make sure ffmpeg is installed): for file in *.3gp; do ffmpeg -i "$file" -af "volume=15.0" ./conv/"${file%.3gp}".mp3; done The line above will increase sound 15X for all files with .3gp extension in the current directory and saves the resulting .mp3 files into ./conv subdirectory (make sure it exists).
