Prefer ObsoletedUser over NewUser for breaking changes
When updating a variable or type, it is a better practice to rename the old one to ObsoletedX and keep the active one as X. This approach enhances clarity, simplifies transitions and refactoring, minimizes errors, and improves overall code readability and maintainability. Adopting this naming convention is a small but powerful step towards writing cleaner, more maintainable code. In the ever-evolving landscape of software development, updates and refactoring are routine. However, the manner ...
Tip: Include email in notification message when sending confirmation mails
If you are a web developer and needs to handle user registration the you probably are sending out confirmation emails to users to ensure they’ve entered a valid email. Lots of web sites (and apps) are showing a message saying “We’ve send you a confirmation mail. Please check your mailbox”. Tip of the day is this - make sure to include the actual email in that notification message. In case a user actually entered a wrong email he will notice immediately and doesn’t need to refresh his email ...
Tweak AppCode font aliasing on your mac
If you can’t use your beloved Monaco font in AppCode because it has gained weight and simply looks too bold, you might want to trim your anti-aliasing settings. Try running this in your terminal $ defaults write com.jetbrains.AppCode.plist AppleFontSmoothing -int 1 You might tweak it even more by using different values for -int 1 e.g. 0, 2 or 3. I’m not changing the system wide font smoothing setting, but only the one for AppCode.
Immediately flush IIS log for real time tail to avoid 60 second buffer delay
I wanted to tail my IIS log in realtime to avoid having to wait 60 seconds as is the default on IIS 7. I found out that I could run the command > netsh http flush logbuffer This is great but I wanted to do a tail so this short script does the trick for you (I assume you have cygwin installed if you’re on Windows) Run command every second in the background and flush output (the “Ok.” message) $ while true; do netsh http flush logbuffer > /dev/null; sleep 1; done & Then you’re ...
How to slice a PSD for use with iPhone & iPad
If you are designer doing iOS interfaces and want to help your developer, these guidelines are for you. Slice both a regular and Retina version. Retina files are postfixed with “@2x.png” (for “two times”) e.g. “account.png” vs “account@2x.png” Retina files must be placed in same folder as its non-retina brother Retina dimensions must be dividable with 2 e.g. 25x13 is not a valid retina dimension but 26x14 is fine All files should be of type PNG (24bit if necessary) Background files might be...
Resolving DNS issues on my ThinkPad running Windows 8
I just installed Windows 8 but had a hard time figuring out why not all sites were available. I quickly found out the DNS lookup failed. Since I had to uninstall my ThinkVantage WIFI manager before installing Windows 8 I assumed it could have something to do with an invalid configuration. I had to reset my TCP/IP stack before I got it to work which is done using C:\> netsh int ip reset reset.log followed by C:\> netsh winsock reset catalog It should do the trick – you might have...

A quick Rails guide for designers
I almost always work with great designers when building Ruby on Rails web applications. These designers are capable of doing amazing HTML and CSS and are already able to navigate a RoR directory structure or able to do so after a quick intro. I’m not focusing on this basic structure convention in this guide but instead I will be taking designers a step further and actually enable them to add a little bit of functionality to views i.e. enabling them to control some logic in *.erb.html files lo...
A bash version of keep_releases known from Capistrano ruby scripts
Today I needed a clean up feature in my bash script similar to what’s known from Capistrano when using the “keep_releases” argument. I wasn’t able to find a simple version so I created it myself. Maybe others find it useful too so here goes releases_path=/data/sites/yoursite.com/releases # change this keep_releases=5 versions=`ls -xt $releases_path` releases=(${versions// / }) # check available number of versions in releases directory releases_count=${#releases[@]} if [ $releases_count -...
Finding Apache configuration file (httpd.conf) location
Just a quick tip for programmers working with Apache. Sometimes I’m asked where to find the Apache configuration file on a given server. Since it’s possible to configure this there is no “default location” so I usually do: $ ps -ef | grep apache which gives me a list like deploy@cmd01:/$ ps -ef | grep apache root 4053 1 0 06:26 ? 00:00:04 /usr/sbin/apache2 -k start www 5189 4053 0 11:00 ? 00:00:00 /usr/sbin/apache2 -k start www 5199 4053 0 11:00 ? ...
