Keep animated images after uploading to WordPress

By , May 11, 2019 5:32 pm

Haven’t written in a while. Not that nothing interesting happened, but never got around to. But I finally moved my blogs to AWS Lightsail (very smooth process, by the way) and experienced only one hurdle I wanted to write about (surprisingly, not related to AWS).

After the migration, I noticed that all images on my Fitbit Clock Faces site lost their animation. When I inspected an image – I found that it’s source goes thru some kind of a proxy “i1.wp.com”. After digging a bit I found that it is used by JetPack site acceleration service – it caches images to serve them faster. Unfortunately cached copies seem to lose some of their properties (like animation).

To fix it – go to JetPack settings and turn “Speed up image load times” off

Disable JetPack image caching

Happy blogging!

Copy/Paste image into an editable DOM element in Chrome

By , September 11, 2017 4:29 pm

All major browsers allow to paste image directly into a DOM element with contentEditable property set to true. They automatically convert it into IMG element with source pointing to base64 encoded DataURI of the pasted image. That is all browsers, but Chrome. Chrome needs a little help.

In my particular case I need to be able to paste image into an IFRAME with editable body of the content document (for some reason Infragistics WebHtmlEditor ASP.NET control renders itself as this contraption). But the code below applies (with small changes) to any editable DOM element.

To achieve the result we need to perform 3 tasks:

  1. Capture image from the clipboard
  2. Convert the image to DataURI format
  3. Create IMG element with the DataURI source and insert it into the DOM

Take a look at the code below: Continue reading 'Copy/Paste image into an editable DOM element in Chrome'»

Tweet images with Scriptr and IFTTT

Sev Trek

Looks like everybody is doing Twitter bots these days so I decided to try my hand on one as well. And it had to be something lighthearted – to let people’s mind off things for a while. Way back in early 2000s there was a funny parody comic of Star Trek called Sev Trek. Original site is gone now, but archive of images was saved at http://sevspace.com/stupidarchive/sevtrek.asp.htm. Images are numbered sequentially – ideal for automatic processing. My bot would tweet random images every couple hours.

To host bot’s script I decided to go with Scriptr which offers powerful JavaScript backend and multiple expansion modules. And IFTTT has a cool Twitter service, one that can tweet image from an URL. So the idea was:

  1. Code hosted at Scriptr generates URL pointing to an image at sevspace.com
  2. Code then call Maker service of IFTTT – custom service capable of accepting HTTP requests
  3. Maker service triggers Twitter service and passes URL of image it got from Scriptr code
  4. IFTTT Twitter service tweets the image

Full control of your LimitlessLED/Milight – v6- bulbs from Amazon Echo

By , February 24, 2017 9:42 pm

A while ago I blogged about controlling you Milight smart bulbs from Amazon Echo. This was done by sending raw UDP packets directly to Milight bridge. Since a packet consisted only of a few bytes – this was manageable.

Then we got v6 of Milight bulbs. They’re vastly superior to previous version – besides brightness and color you can set warmth and saturation among other things. But with new features came increase complexity of commands. UDP packets now consist of huge number of bytes and you cannot simple send packet and forget it, response matters too.

HA-Bridge, which is used to emulate Phillips Hue bulbs so Echo can detect the devices, is incapable of such commands. Thankfully it can run external scripts. Continue reading 'Full control of your LimitlessLED/Milight – v6- bulbs from Amazon Echo'»

Using FusionCharts in SSRS reports

By , January 30, 2017 12:11 pm

Microsoft’s SSRS is pretty advanced reporting system with multitude of advanced features. SSRS also has charting capabilities, but it’s somewhat lacking compared to more advanced desktop or web charting suites

On the other hand FusionCharts offers very cool charting package with gazillion of chart types and very cool features. But it uses JavaScript engine and renders charts client-side only!

What if there was a way to marry the two technologies together – to render cool FusionCharts in advanced SSRS repots? Continue reading 'Using FusionCharts in SSRS reports'»

There’s new reflective LCD in town (SMA Q2 vs PTS)

By , January 20, 2017 12:23 pm

I’ve been a fan of Pebble smartwatch for a very long time, both as a user and developer, but recently, even before announcement of Pebble acquisition by FitBit I got curious – what else’s out there? Two mainstream branches of smartwatches – Android Wear and “The Watch” are of no interest to me – too boring. So I looked into Samsung Gear watches – Tizen platform is very interesting, then it was Vector Watch (which ended up being bought by FitBit as well) and now a new ePaper watch from Chinese company Shenzhen – SMA Q2 (sometimes called SMA Time).

There is no question that despite obvious visual similarities, at this point in time Pebble Time Steel is vastly superior to SMA Time. PTS is on 4th generation firmware which brought many advanced features over the years, PTS has a very popular appstore and high quality developer ecosystem. SMA Time feels like Pebble circa firmware v1.x (probably even less, e.g. it has only 3 slots for watchfaces on the watch) but it seems to have great potential.

I am posting here a few pics comparing PTS with SMA Time. Continue reading 'There’s new reflective LCD in town (SMA Q2 vs PTS)'»

SSRS and HTML rendering of ordered list

By , November 14, 2016 2:02 pm

Microsoft’s SQL Server Reporting Services supports rendering of HTML tags, but for some reason that support stuck in 1990s – only very limited set is supported. And even using that set is problematic.

Case in point – ordered list. While officially supported – the way it is rendered is the stuff nightmares are made off. Jumble of original tags generously intermixed with DIVs and SPANs – it’s a wonder it renders at all.

And sometimes it doesn’t. If you try to view a report in Internet Explorer (especially from older, but still actively used versions of SSRS like 2008) numbering get screwed.

Simulating Pebble GPath in Rocky.js

By , August 17, 2016 3:56 pm

RockyJS is a black magic voodoo from Pebble Dev team. It allows you to run your JavaScript code on the actual smartwatch (unlike PebbleJS that runs on the phone). When RockyJS debuted it ran as a simulation in a browser, but since then it matured and now runs in Pebble emulators and on actual hardware.

RockyJS changed drastically since that web release. It resembles C code less and takes more standardized JavaScript approach. During that transition some features were lost. One of them is Pebble GPath concept – a graphical object that consist of set of coordinates that you can freely move and rotate. In particular missing commands gpath_move_to, gpath_rotate_to and gpath_draw_outline that move, rotate and draw the GPath. When I was porting my first Pebble watchface to Rocky I used those extensively. You can read about that implementation complete with the source code here. But now the commands are gone and I needed a substitution. Continue reading 'Simulating Pebble GPath in Rocky.js'»

Future Time – watchface for Pebble smartwatch

By , July 17, 2016 1:32 pm

http://tinyurl.com/timefu

This is the face of the future.

Two faces actually – because you get both analog and digital face – and it’s up to you which one to use. You also get eight predefined color themes as well as ability to set each color individually. This face also provides weather and fitness tracking at your fingertips. And it just looks cool.

Key features:

– Digital or Analog face type selection
– Multiple color themes as well as custom color settings (or you can leave it on auto and the color will depend on battery level)
– Weather (powered by Forecast.io), Step Counter, Distance Walked, Sleep Hours
– Bluetooth Connect/Disconnect alert of configurable intensity with visual clue
– Battery level represented by percentage number as well as visually by outer perimeter of dots (also by watchface color – if in auto color mode).
– Visual step goals

$0.99

After installing watchface you have a 3-day trial period to explore all the features and different aspects. At the end of trial if you like Future Time and want to keep it – it’s just $1.50 USD via Kiezel Pay payment system, you will be prompted to enter code and follow few easy payment steps. Once purchased – the watchface is yours permanently, no matter what Pebble or what phone you use, as long as you keep the same Pebble account.

You will need to get free key for weather services at https://developer.forecast.io – this is one time procedure.
