Revived Baby Art on the App Store
After not having updated Baby Art for years, it was removed from the Apple App Store. I initially created this app as a very simple drawing tool for the iPad, designed for my daughter when she was still a baby. The idea was simple: open the app and the baby can draw with their fingers in various colors and shapes. It automatically changes colors and shapes with each stroke and also randomly plays some baby sounds. Recently, I decided to revive it. Ten years ago, all the drawing handling had...
Projects page updated with screenshots
I tried to find some old screenshots of the projects and updated the projects page so it looks a bit better. I’m considering reviving some of the projects so they can get back running instead of just being the source code you’re able to see.
Building a simple Tic-Tac-Toe game
Yesterday, I found myself needing to pass some quality time with my daughter and we decided to play tic-tac-toe. To my surprise, there weren’t many options for a simple tic-tac-toe game that allowed two people to play remotely by just sharing a link. Sure you have lots of options if you download a game or want to go to a website and press through 438 ads before playing, but I was looking for a straightforward page where you could click “new game,” and then easily invite someone to join by sha...

Getting back into Rails 7 from Rails 2.3 😱
I’ve decided to revisit Rails after more than a decade of not using it. I have always loved it and created many applications when I was a Ruby on Rails consultant around 15 years ago. I have over 25 RoR applications I could try to migrate from an old Rails version to the new one. However, after a couple of quick attempts, I decided it’s not worth it because so much has changed, and it’s hard to determine the best migration path. Instead, I just set up a clean new Rails 7 app and transferred ...
RSVP: It's Not Just a Polite Request, It's a Reading Revolution
When most of us see the letters RSVP, our minds instinctively translate it to “Répondez s'il vous plaît,” a fancy way of asking us to confirm our attendance at a soirée. But in the world of cognitive neuroscience and advanced reading technologies, RSVP stands for something far more intriguing: Rapid Serial Visual Presentation. It’s not about politely declining a wedding invitation but about turbo-charging our reading speed. What is Rapid Serial Visual Presentation (RSVP)? Rapid Serial Visua...

What is an Online Diary?
History Online diaries have been around since at least 1994, starting a new way for people to share their thoughts and experiences. At first, these diaries were called online journals and created communities of people sharing their daily lives. Over time, the term ‘blog’ became the common name for these journals. ‘Weblog’ was the original term, later shortened to ‘blog.’ Evolution As technology advanced, private and secure online diaries emerged. These digital diaries replaced traditional ...
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...
Restore full backup of Redmine from Google Storage
Restore database from dump file # required settings DB_USERNAME='<redmine db username>' DB_PASSWORD='<redmine db password>' DB_NAME='<redmine db name>' REDMINE_ROOT='<full path to redmine root>' # e.g. /home/peter/rails/redmine.commanigy.com' BACKUP_ROOT='<full path to backup root>' # e.g. /home/peter/backups (will be created) RESTORE_FROM='<date in YYYYmmDD format>' # e.g. '20110201' for February 1, 2011 $ mysql -u $DB_USERNAME --password=$DB_PASSWORD $...
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 ? ...
How to hide icon in your dock for any Mac application
Just got a beta of a Mac notifier for Podio and didn’t like it showed both an icon in my menubar and my dock (sometimes also referred to as the taskbar). If you want to avoid having any Mac application shown in your dock, it’s possible to patch its package by doing these simple steps Open Finder and browse to your application Right-click the file and select “Show Package Content” Browse to “Contents” and open “Info.plist” If you find an element called “Application is agent (UIElement)” ...
Use sensible defaults when building a web, mobile or desktop application
While working on migrating “gomore.dk”, a Danish ridesharing service, to Rails 3, I figured it would make sense to look into the existing database to figure out if I could add some sensible defaults when creating e.g. new rides. The site already contains a decent database so I figured it would be rather easy to measure which defaults to use. As an initial example, I would like to know how many seats were shared on each trip and therefore I did a simple query as shown below: From this, ...
An error occurred while validating. HRESULT = '8001010E'
Just a quick tip. While upgrading one of my projects from VS.NET 2008 to VS.NET 2010 I ran into a problem I wasn’t able to find a correct solution for it anywhere. While building my setup projects I got: An error occurred while validating. HRESULT = ‘8001010E’ Various posts suggested to remove all dependencies but in my case it was caused by an invalid reference to the framework. This is what I did to have it compile again: Right-click .vdproj Select “View” | “Launch Conditions” Right-c...
Universal builds for Mac App Store with Xcode
While working on Wallpapery, I had to do a universal build for both 32- and 64-bit. I expected I should simply set “Architectures” to “Standard (32/64-bit Universal)” but after approval in Mac App Store and user complaints I found out, I had missed a couple of steps. To build your product for both 32- and 64-bit architectures (aka i386 and x86_64) you have to explicitly unmark “Build Active Architecture Only” and filter list of “Valid Architectures” to only list “i386 x86_64” I wasn’t awa...
How to get display name from NSScreen
While working on Wallpapery I needed to get a given screens display name. There is no “displayName” method on NSScreen so I added a category to provide this functionality. Seems like others are looking for this too so I’m posting my code below. NSScreen+DisplayName.h #import <Cocoa/Cocoa.h> @interface NSScreen (DisplayName) - (NSString *)displayName; @end NSScreen+DisplayName.m #import <IOKit/graphics/IOGraphicsLib.h> #import "NSScreen+DisplayName.h" @implementation NSScr...
Send your weight from an iPhone through SMS
While working on lifestyleapps I have been asked a couple of times, if it would be possible to report your weight by sending an SMS from your phone. This is already possible and I have been using it from my iPhone 3G for a long time. The trick is to associate your Twitter account to your lifestyleapps account and set up your Twitter to accept SMS. In order to report your weight you need to follow @reporting which is the lifestyleapps Twitter account and by following this (and it will follow ...
How to send mass text messages from your own number
A couple of months ago we needed to make a service which would be able to send out sms text messages to a large number of people. The text message itself should come from a specific number so recipients would be able to reply back for more information. Another requirement was the ability to send a text message to a specific number and then trigger the mass sending to the configured recipients. The part sending out bulk sms is easy. A lot of companies have great, simple APIs to do this but t...
UIModalPresentationFormSheet width and height for an iPad in landscape mode
In a recent application I was doing, I was designing an interface to be shown as a modal form sheet using setModalPresentationStyle:UIModalPresentationFormSheet. I searched the Apple documentation to find the exact dimensions of this sheet but it isn’t documented. It only states “The width and height of the presented view are smaller than those of the screen and the view is centered on the screen. If the device is in a landscape orientation and the keyboard is visible, the position of the vi...
How to backup Redmine on Google Storage
If you would like to backup your Redmine database and files, you might to consider Google Storage as your backup location. It comes with a 100 GB free monthly usage. First, you need to sign up for a Google Storage account if you don’t have an account already. Once done, download and install GSUtil which is a command line tool, allowing you to manage buckets. Paste the following script into a file called “backup_redmine.sh” # required settings DB_USERNAME='<redmine db username>' DB_...
Using vi for your simple, day-to-day editing needs
My favorite editor isn’t vi, but I’m still using it at least a couple of times each day. It’s a short two character command, it’s always available and it starts fast. I have used it for decades and still, I only know these commands. I really don’t need to learn any others, contrary what some of my friends tell me. Need to know j = move down k = move up l = move right h = move left i = go into “insert” mode = go into “command-line” mode ESC = go out of current mode x = delete chara...
Lesson learned: Put limits on anything you provide for free
With our ShoutSMS service, we provide three free sms credits just for signing up. We do this to allow new users to try our service, without having to buy initial credits, just after they sign up. After initial launch, we almost immediately got people from India hitting our servers. They signed up, confirmed their number and tried to send overtaxed sms to various numbers. Because I had chosen an initial credit limit and a max cost limit on each sms, it was avoided. I know from my previous ...
Marketing tip: Include link to your app in newsletters
I have registered on a lot of sites and opt-in for their newsletter to be notified of updates. One thing bugging me is, when a site sends a great mail in their newsletter but doesn’t include a direct link to their web site. The mail is coming from their domain so it isn’t hard to guess but users are lazy! Since I’m registered on too many sites to visit regularly, I probably do want to visit a site, if it contains exiting updates but I have to admit, that without a direct link, I might not g...
Upgraded ShoutSMS from Rails 2.3.8 to Rails 3 in five minutes
Today I wanted to try how easy it would be to upgrade our existing ShoutSMS (pretty small) Rails application from 2.3.8 to latest Rails 3 release candidate (currently rc3). Without taking our test suite into consideration it took around five minutes with help from the official rails_upgrade[1] plugin. This is fast, yes, but considering the size of this app and possible pitfalls I am not looking forward to upgrade our larger projects. These are the basic steps to perform Install rails_upgra...
Facebook CSS for will_paginate gem
Today I needed to add pagination to our Danish beta application for handling your accounting called Hurtigmoms (defunct). Since we’re developing in Rails it was a logically choice to use “will_paginate” to support pagination. Our prototype layout is using a Facebook header and so I wanted my pagination control to mimick their style. If you need something similar you might want to take a look at my CSS styles which are using the default class names used by will_paginate. .pagination { ...
Tracking coffee intake with touchatag and Lifestyleapps
I have bought a touchatag RFID reader and a couple of touchatag RFID tags and was wondering how I could use these to track my daily intake in lifestyleapps. I noticed a Twitter application already has been developed which post a message from a configured account. Since lifestyleapps already integrate with Twitter it was a simple matter of associating a direct message and prefixing it with “h” or “having” to let lifestyleapps know you are reporting an intake. Many cups of coffee are consu...
Today, we have taken over development of ConquerCam
Today, we have taken over development of ConquerCam. ConquerCam is a low-priced (less than twenty bucks) webcam software package for Windows having quite a few cool features such as built-in web server, motion detection and scheduled uploads via FTP. ConquerCam was initially developed by me back in 1998 and at that time it was surely one of the very best in its category. Lacking time I stopped active development in 2003 but didn’t really give up on it since I continued to get feedback. Con...
Upgrading Rails Engines Project to Rails 2.3.2
Our lifestyleapps project (still in very early beta) was running Rails 2.2.2 with the Rails Engines plugin ten minutes ago. Today, Rails 2.3.2 was released so I decided to try if I could easily upgrade it and avoid using the Rails Engines plugin anymore. It was beautiful simple and took me less than ten minutes. First, I had to update our Apache Passenger module with a version supporting Rails 2.3 so I did a $ gem update passenger and then run the install to build our apache module $ pas...
Extend your shell toolbox with pbcopy
We are developing Rails applications on Mac OSX and a command which isn’t used enough in my opinion is “pbcopy”. This command will allow you to grab the standard input from a terminal and put it on the clipboard. I find myself using commands such as “pwd | pbcopy” all the time. This will grab my current working directory and make it available in my clipboard allowing me to easily paste it into another terminal or application. This avoids the need for you to grab your mouse to paste a simple ...
