published 239 days, 7 hours, 57 minutes ago posted by

oazabir 247 days, 8 hours, 58 minutes ago

If you have a custom font in any CSS, anywhere on the page, most browsers (like IE) will not render anything (remain white) until the custom font is downloaded, initialized and applied. Usually custom fonts are over 300KB. As a result, they significantly slow down page load speed. Learn how to overcome this. (more)

ReadLine on Binary Stream

posted by

oazabir 414 days, 14 hours, 10 minutes ago

When you are reading data from a binary stream, like NetworkStream or FileStream and you need to read both binary chunks as well as read one text line at a time, you are on your own as BinaryReader nor Stream supports ReadLine. You can use StreamReader to do ReadLine, but it does not allow you to read chunks of bytes. The Read(byte[], int, int) is not there on StreamReader. Here’s an extension of BinaryReader for doing ReadLine over a binary stream. You can read both byte chunks, as well as read text li... (more)

Memory Stream Multiplexer–write and read from many threads simultaneously

posted by

oazabir 414 days, 14 hours, 13 minutes ago

Here’s an implementation of MemoryStream like buffer manager where one thread can write and many threads can read simultaneously. Each reading thread gets its own reader and can read from the shared stream on its own without blocking write operation or other parallel read operations. It supports blocking Read call so that reader threads can call Read(…) and wait until some data is available, exactly the same way you would expect a Stream to behave. (more)

Caching WCF javascript proxy on browser

posted by

oazabir 414 days, 14 hours, 14 minutes ago

When you use WCF services from Javascript, you have to generate the Javascript proxies by hitting the Service.svc/js. If you have five WCF services, then it means five javascripts to download. As browsers download javascripts synchronously, one after another, it adds latency to page load and slows down page rendering performance. Moreover, the same WCF service proxy is downloaded from every page, because the generated javascript file is not cached on browser. Here is a solution that will ensure the gener... (more)

ASP.NET generates some large cookies if you are using ASP.NET membership provider. Especially if you are using the Anonymous provider, then a typical site will send 517 bytes of cookie on every css, js, image request. That's 60 GB worth useless upload for 1M page view.

User story is worthless, Behavior is what we need

published 1019 days, 2 hours, 41 minutes ago posted by

oazabir 1021 days, 6 hours, 24 minutes ago

User Story is suitable for describing what user needs but not what user does and how system reacts to user actions within different contexts. It basically gives product team a way to quantify their output and let their boss know that they are doing their job. As a developer, you can’t write code from user stories because you have no clue on what what is the sequence of user actions and system reactions, what are the validations, what APIs to call and so on. Software, and the universe eventually, is all ... (more)
