I had a pretty common problem with regards to inserting into database tables. As you probably know, depending on your data and foreign keys, you need to insert data in a specific order, for instance, you first need to insert invoice record, and only after that you can insert invoice items. This problem has been already solves so many times, and in different ways (some ORMs inspect your tables and determine dependencies and what goes first, others rely on you to define the order by defining dependencies, and some of them just leave it to you to do the updates...

I decided to start a series of blog posts which would cover some of my favourite patterns and practices in writing good code. The opening post will be about on of my favourite patterns, event aggregator, also known as Publish-Subscribe, Event Publisher, etc. Event Aggregator pattern is well known in the enterprise community, but i still see a lot of solutions which completely ignore this fantastic pattern and rather use conventional hooks or events. I'd say that the event aggregator pattern is one of the most powerful ones to supercharge your conventional CRUD applications. I wanted to use this post to...

Source RavenDbBreeze sample I started taking much more interest in SPA development, and combination from the title has been gaining a lot of popularity lately, so i decided to give it a go. There are a few critical questions that i needed answered and since there are rather new technologies, the information is quite scattered. I looked at a bunch of technologies, stacks, trying to get a hold of the best solution. Eventually i decided on doing some forking on the NoDB sample project from Breezejs and see if i can bend it to my will. So here is my...

I recently got myself a Surface RT and although i love the device, there are some quirks that need ironing out. One of the most often uses for these devices is playing videos and music, and since Windows RT is pretty aggressive with power management, and admittedly doesn't have an official youtube app (which means you can't play all the videos on unofficial ones), the only good option is playing through browser. There are 2 things you can do about this:

1. Play streaming on the desktop version

Just a quick tip for anyone facing this error. If you are doing customization of your themes or functions, you could face with the following error when trying to connect Jetpack: Jetpack could not contact WordPress.com: register_http_request_failed. This usually means something is incorrectly configured on your web host. SSL certificate problem: self signed certificate in certificate chain If you go to your jetpack.php file and change https://jetpack.wordpress.com/jetpack to http://... you will get a different error which is closer to the real reason: Your Jetpack has a glitch. Something went wrong that’s never supposed to happen. Guess you’re just lucky: xml_rpc-32700 Try connecting again. Error Details: The...

As a side project, I started fooling around a bit with python. Now as usual, first i started to look around a bit, see what's out there, what's the best practices, best IDE and all that. My first idea was to install python, mysql and django side by side with everything else on my windows machine, but the more i thought about it, the messier it got. So i went with option no.2 and that would be a VM. Now, my linux knowledge is pretty bad, and i really didn't feel like setting up and fiddling with another OS with GUI, especially...

Well it's just a quick one but it's kinda cool:) I know lots of you have been doing this "initialize once" type of code 1 Well, to save a few keystrokes you can do it like this 1 Haven't seen it around, so just to put it out...

Here's a quick tip. If you are looking to change the name on all columns in a database, for instance on primary key, you can do it by outputing the next SQL statement to text and then executing the text. 1 Quick and...

One remark: in code snippets, please take not of the wrong formatting for "<" and ">" (it's shown as > and < signs). There are other signs too that could be different but my code snippeter is a bit moody today:) Telerik reporting is a great tool for just that, but if you feel like doing it OOP style, using your existing architecture, and doing it with some kind of IOC, then you have to do some minor adjustments. Say you want your Invoice report to use you repository, through your constructor: 1 There's another interesting bit here (that this.Field extension method) but i'll...
