website productivity performance

5 Easy Steps to Boost WordPress Speed & Performance (No Coding)

First of all we need to understand why the speed performance of our wordpress website is so important.

Study says that

Average human attention span has dropped from 12 seconds to 7 seconds in the last 10 years.

It means that you have very little time to present your content, on the best way, to your visitors so they be attracted and stay on your website for a longer time without loosing interests or patience. If the website is slow the visitors will leave it before it even loaded.

Google study sais

1 second delay in page load time lead to 7% loss in conversions, 11% fewer page views, and 16% decrease in customer satisfaction.

So losing visitors you lose clients and money. Because of that speed performance of the website is so important for you benefit business.

Not at the last stage is good to know that Google and other search engines have already started penalizing slower websites by pushing them down in the search results. This means lower traffic for your slow website.

What we can do to speed up our wordpress website?

1. Check your wordpress speed

There are several free tools online that you can use to check your wordpress website speed performance. Here you can find the most popular and user friendly:

  1. KeyCDN Speed Test
  2. Google PageSpeed Insights
  3. Pingdom
  4. GTmetrix
  5. WebPageTest
  6. DareBoost
  7. Varvy Pagespeed Optimization
  8. UpTrends
  9. dotcom-monitor
  10. PageScoring
  11. Yellow Lab Tools
  12. Google Chrome DevTools
  13. Sucuri Load Time Tester
  14. Pagelocity
  15. YSlow
  16. PerfTool


2. Find what slow your wordpress website

Checking the speed of your wordpress website can help you analyze:

  • Scripts, fonts, and plugins causing load time issues (HTML, Javascript, CSS)
  • Finding large images
  • Render-blocking JavaScript or CSS
  • Total load times, page sizes and requests
  • Performance from different geographical locations
  • Rendering speed in different browsers
  • HTTP Headers

Using any of these key also can help you to measure the performance of your Content Delivery Network (CDN).

3.  Understand how to improve your website speed and make the improvements

Step 1: Install a WordPress Caching Plugin

There are a lot of caching plugins available for WordPress, but we recommend using the WP Super Cache, W3 Total Cache or WP Rocket plugin. Check out step by step the relevant guide on how to install and setup any of these plugins on your WordPress site.

Why to do that?

Because the WordPress pages are “dynamic pages”. This means they’re built on the fly every time someone visits a post or page on your website. During this process the active data is often cached in order to reduce load times.

Caching plugins work is to save the dynamically generated HTML files and serving them from the cache (i.e. reusing previously generated data) whenever a request is made, rather than loading all of the PHP scripts from WordPress every time you hit refresh.

Step 2. Optimize Images for Speed

The best way to optimize your image sis to use Photoshop, but some image optimization plugins are also available in the wordpress repository as free.

Why to do that?

Using images makes 80% of the visitors more likely to read your content.

But non-optimized images are one of the most common speed issues you need to solve.

Before upload a photo directly is good to use photo editing software to optimize the images for web. In their original formats photos can have huge file sizes. Most popular web image formats are JPEG and PNG. We recommend to use one of them.

How to select the image format?

JPEG – if the image has a lot of different colors.
PNG if you need a transparent background of the image.

Step 3. Use Excerpts on Homepage and Archives

Step 4.  Don’t Upload Videos Directly to WordPress

If you use slider or image gallery try to find and install the most faster slider or image gallery plugins and optimize your wordpress database.

4. Keep your wordpress site updated

WordPress is an open source project that is updated frequently. You need to check regularly for updates and run them as soon as the updates are available. You need to update not only the theme you use, but also the WordPress in general and all plugins you use.

5. Constantly keep checking your wordpress website speed and make some corrections if it needed

Follow all the steps above in a regular time, so to be sure you will remove on time all speed negative effects.

Android Studio

Android Studio – Integrate APK Expansion Files

This article intents to clarify the process of integration of the Android APK Expansion Library with Android Studio.

Following the original documentation on how to integrate the Android APK Expansion library, and wasting time to investigate why the explained steps don’t work, provoked us to write this article.


In this example we are using the following versions:

Android Studio:  2.2 RC
Android SDK Platform: 24

I. Pre requires and file locations

First, you need to install the Android SDK

To integrate APK Expansion library, you need to import 3 libraries from your local Android SDK:

  1. play_licensing/library
  2. downloader_library
  3. zip_file
Required Libraries

The libraries are located in:


II. Import Libraries in Android Studio

Before you begin, you need to change the following line in the Android SDK downloader_library file:

Change line

Since the downloader_library depends on the play_licensing library, we must change the reference parameter to point to the correct directory.

Obviously, Android SDK has changed the name of the play_licensing library on some point without changing the reference in the properties file.

Now you can import the required libraries in your Android Studio IDE:

Open Android Studio (and your project respectively) and click on Import Module… ( File -> New -> Import Module… )

Import new module menu

Then, from the open window, type the path to the library you want to import. E.g:


Then click Next and leave all check-boxes as are. Then finish the operation.

Hint: If you import the downloader library first, the licensing library will be imported automatically  as well.

Repeat this step for zip_file library as well.

New Module window

Now, the Android APK Expansion library should be imported correctly.

In your project, the imported libraries should appears like this:

Imported modules

Next: Do not forget to add these libraries in your project dependencies:

Add module dependencies

III. Additional issues

In case your build failed with some of the following exceptions

Error:(23, 23) error: cannot find symbol class Header

Add in your file (including these of the libraries), the following line:

useLibrary 'org.apache.http.legacy'

This line must be added in android {….} block. E.g:

android {
    compileSdkVersion 24
    buildToolsVersion '24.0.1'
    useLibrary  'org.apache.http.legacy'

Also, copy org.apache.http.legacy.jar in your apps lib folder. This file is located in:

/your SDK directory/platforms/android-XX/optional/org.apache.http.legacy.jar

Then, add this file as a library (right click on the jar file -> Add as library)

Putting org.apache.http.legacy.jar in your local lib folder causes Multiple dex files define exception when building your app.

Error: java.lang.IllegalArgumentException: Service Intent must be explicit: Intent { }

This is a known bug.
In change from this:

boolean bindResult = mContext.bindService(new Intent(new String(Base64.decode("Y29tLmFuZHJvaWQudmVuZGluZy5saWNlbnNpbmcuSUxpY2Vuc2luZ1NlcnZpY2U="))),
                                          this, // ServiceConnection.

to this:

boolean bindResult = mContext.bindService(new Intent(new String(Base64.decode("Y29tLmFuZHJvaWQudmVuZGluZy5saWNlbnNpbmcuSUxpY2Vuc2luZ1NlcnZpY2U=")))
                                    this, // ServiceConnection.

We are not going to dive into the usage/functionality of these libraries.

Details about how to integrate and use the APK Expansion Library, you can find in the original Google Android Development documentation.

IoT платформи за един свързан свят

Интернет на нещата (IoT) е концепция, много по-различна от интернета от вчера. Въпреки че технически погледнато това е един и същ интернет, то процесите и функционалността на свързаните устройства, които съществуват в него не са точно типичните, с които сме свикнали да работим. Много от тях нямат дисплей за визуализация, други изпълняват комплекс от различи дейности и задачи, а трети пък служат само за предоставяне на данни за или до един конкретен обект.

Всъщност интернет на нещата включва почти всичко, което може да си представи човек, от автомобили и къщи до комплексни инсталации и процеси. Широко се дискутира дори и концепцията за т.н. “умен прах”, който ще събира и предоставя информация за всичко, в досег с въздуха, около нас.

На интернет на нещата (IoT) трябва да се гледа като на платформа за развитие, с изключително разнообразен обхват и функционалност. Това разнообразие е още по-ясно изразено при преглед на широкия спектър от платформи, навлезли вече на пазара, които може да се базира разработването на редица IoT проекти.

Софтуерно и хардуерно бъдеще на IoT

Голяма част от разработчиците вече са съсредоточили усилия в използването на възможностите на IoT за създаване на решения за промишлеността, здравеопазването, потребителските пазари, и то с главоломна скорост. Едно скорошно проучване на Evans Data Corporation разкрива, че 45% от всички работещи разработчици приемат IoT решенията като важен приоритет в своята дългосрочна стратегия за развитие.

Същото може да се каже за хардуерни инженерите. Независимо от това дали работят върху гигантски индустриални машини или миниатюрни сензори, IoT е преобладаваща част и от тази дискусия.

От гледна точка на потребителите, тези умни неща, които се свързват към Интернет постепенно навлизат в домовете им, колите им, а дори и в гардероба им се приемат радушно, което определя един безкраен хоризонт за иновации в IoT.

Почти безкраен брой платформи за разработка
Да кажем, че имате някакъв опит в софтуерното разработване и имате идея, която искате да се превърне в интелигентна устройство, като част от интернет на нещата. Следващата стъпка е създаването на работен прототип на концептуалната ви идея, като изберете най-подходящата за целта платформа. В момента има много и разнообразни платформи, между които да избирате.


Arduino board

От хардуерна гледна точка, Arduino платките са страхотни за един добър старт.  Те се предлагат в различни размери, конфигурации и форми, като по този начин покриват широк спектър от основни функционалности и улесняват разработчиците при интегриране на софтуерна платформа към конкретния проект.

Arduino е с отворен код и за него се разработват много други елементи и платки съвместими с него, което го прави невероятно гъвкава платформа при разработване на разнообразни IoT проекти (от управление на лапите в къпи, градинското напояване, отоплителната система в къщи до по-сложни роботизирани процеси).

Arduino предлагат дори системи специално разработени за деца.


Raspberry Pi

Raspberry Pi board

Raspberry Pi е друга голям хардуерна платформа (платка) използвана за разработване на интернет на нещата. Безплатни инструменти като Node-RED са популярни сред разработчиците, в качеството си на системи за цифрово предаване и съхраняване на данни.



Pycom WiPy board IoT

Pycom е друга алтернатива на платформа за IoT. Една от най-популярните сред преграмистите платка е WiPy. Програмният език е Phyton. Осигурява перфектно съчетание на мощност, бързина и гъвкавост. В рамките на няколко минути можете да се свърже безжично към него и да получите Python REPL команден ред.



Intel IoT Galileo

За по-големи и по-широкообхватни проекти Intel предоставя своя собствена платформа на интернет на нещата, която се характеризира с висока сигурност и надеждност, лесна комуникация както между самите устройства така и между устройствата и облака.

Ето от най-големите предимства на IoT концепцията е, че невероятно лесно могат да се намерят ралични инструменти с отворен код (на достъпни цени), с които всяка иновативна идея лесно може да се превърне от концепция в реален прототип.

Въпреки високите темпове на развитие, това все още е нова концепция и много от решенията и инструментите тепърва се разработват и то не от големи корпорации а от привърженици на интернет на нещата, което е още една възможност за възникване на иновативни и предприемчиви фирми.

Chromium project of Google

Each website become webVR with Chromium project of Google

The new big target of Google is to allow each website to be visible as webVR with the new project Chromium.

WebVR support is available as experimental flag in chrome://flags/#enable-vr-shell only. But is expecting to change the way of how we browse the Internet, in the near future. In order to enable access to the WebVR APIs in these builds you must turn on the “Enable WebVR” flag in about:flags or launch from the command line with –enable-webvr.

François Beaufort from Google said, the Chrome Beta and Chrome Dev channels will have additionally added new settings, that the user will be able to activate and change the way of internet surfing into virtual reality, using Cardboard or Daydream-ready viewers.

And this is just the beginning. The entirely new platform of google Daydream (for high quality mobile virtual reality) coming in Fall 2016.

WebVR will be the new way of internet surving and visuailization of the information.

Chromium project of Google

Google – всеки сайт видим във виртуалтана реалност

С новия си проект Chromium, Google се стреми да направи всеки уебсайт видими в VR, т.е. всеки уебсайт WebVR.

С новите технологии залегнали в проекта Chromium, се очаква коренна промяна на начина, по който сме свикнали да работим и сърфираме в интернет в близко бъдеще

Според François Beaufort от Google, каналите Chrome Beta и Chrome Dev ще имат нови допълнителни настройки, които ще позволяват на потребителя да сърфира в интернет пространството посредством устройства за виртуална реалност като Cardboard или Daydream-ready viewers.

Можете да активирате експиремталния флаг в Chrome ot tuk: chrome://flags/#enable-vr-shell. За да активирате функцията WebVR APIs кликнете върху “Enable WebVR” flag в “about:flags” или я стартирайте чрез командата –enable-webvr.

И това е само началото. Все повече съдържание ще продължава да се появява достъпно чрез тази технология.

Новата платформа на Google за виртуална реалност Daydream, се очаква да бъде достъпна през есента на 2016.

Виртуална реалност като част от интернет браузера на Google се очертава да стане неизменна част от интернет пространството и да промени начина по който ще се представя информацията там.
