Streamed upload example with Swift and Node.JS

Let me show you an example which allows to play with streamed upload (also known as multiplart upload) right in XCode Playground with Swift language and Node.JS server.

Implementing hybrid hosting model

In previous post I’ve introduced concept of hybrid model which allows to scale web applications, such as magento, horizontally with a minimum effort and investments. And now I’d like to show you quick implementation example.

Magento scalability made easy

In a situation when vertical scaling isn’t flexible and horizontal is expensive the hybrid model comes to the rescue.

Efficient iteration of the new feature

Developers often presented with the problem followed by complete UI design or specification, which, beside the original problem, often covers additions which might improve overall user experience regardless the level of importance.

Get access to printers from web application

Let’s say we’re developing web-based POS system, where receipts needs be printed on the special kind of printer, but we don’t want user to deal with printer confirmation dialog, which will appear each time receipt need be printed due to the nature of web browsers.

Things will get even more complicated when we find that POS workplaces has to be equipped with tablets instead of normal PCs

How could we eliminate those issues?

CoffeeScript does not allow loose equality

Today learned that CoffeeScript doesn’t allow loose equality, so, whenever you use == or is it will compile to JavaScript’s === and that’s by design!

Add validation of uniqueness for the existing attribute

Let’s say we have a City model and corresponding UI enabling user to manage the list of cities, eventually we discovered that forgot to add validation of uniqueness for the city names and some users was able to create duplicate entries.

No panic! Let’s fix it now!

Add class attribute to Markdown table

Earlier this week I faced the problem converting Markdown tables to HTML, unfortunately there was no way to specify custom class attribute in resulting HTML.

And that’s was quite critical for me, since my current theme is Twitter Bootstrap based and I have no other choice, but explicitly specify the class names to make styles works.

Applying styles globally, i.e. to every table element, wasn’t an options, because table element is used in some others plugins, for example for sharing code snippets.

After some research, I come up with a simple and straight forward solution :)

Where is my commit?

With continuous integration responsible for deployment, especially in the mid to large size team the following questions might be popping up time to time:

• Is my commit went to production last night?
• Is it on staging?
• Where is my commit?

No worries, GIT got you covered:

1

git branch -r --contains <commit SHA>

This will show all remote branches where particular SHA is found, for example:

1
2

origin/master
production/master

Also, it might be good idea to fetch updates from remote branches in order to cover most recent change sets:

1
2

git fetch production master
git fetch origin staging

You can skip -r flag if only interested in local branches.

Caution!!!

SHA of commit is changed when you cherry-pick and therefore those won’t be shown in result set for the original commit SHA
