Sometimes you need to install a gem in your Rails application for distribution.
If it’s installed as a Ruby gem in your system and you need it to be packaged with the Rails application (/lib or /vendor/plugins directories), go to the target folder and do
gem unpack gem_name
If it’s not installed yet, you need to install it first like below and then do unpacking.
gem install gem_name
I also found several pages that may be interesting:
The default Rails framework seems not support the foreign keys in database migrations and that’s a big omission. You are bound to deal with raw SQL to add these or end up with complex (and often ugly) code to emulate them.
Recently I found a very nice plug-in that adds foreign keys functionality to the migration classes. The syntax looks native and doesn’t stand out prominently. It is also clever enough to recognize some basic intentions, like ‘user_id’ being a reference to the ‘users’ table etc.
Check their other rails works too. They look handy!
First of all, I’m writing this when the most recent firmware version is 1.22. It is important as you may guess from version to version things change, and in case of TC, not necessarily to good.
So you bought one of these Firewire audio-interfaces and tried them with your PC, but you can hear crackles, drop-outs (pauses) and all that unpleasant stuff. Let me show some possible reasons, and see if your setup has similar problems.
All three versions of audio-interfaces use Firewire bus to exchange data with a computer. All of the devices are very sensitive to what’s going on in this bus. When data stops coming, you hear the silence. When an audio stream resumes, you don’t hear silence. These pauses are called drop-outs and happen because your PC is busy with something that claims to be very important while on practice it’s usually a malfunctioning device driver.
It appears Skypecasts aren’t dying, but having some tough times there. Yesterday I had some great fun in one general chat room: met a few new people, showed some of my urban photography works, shared views on modern music influences. Today, I wasn’t able to stay in a room for more than 14 seconds; it simply kicked me out of it and dropped the call all the time.
I can’t get an idea of what’s going on there with Skypecasts. Can somebody enlighten me? I have recently got a headset and decided to have some fun with public chat rooms in Skype, but what I saw didn’t please me at all. There are four to six rooms running at any given moment with almost all of them having no participants. I mean half of these rooms never responded to my call, and the other half had a host user only, which isn’t fun, is it?
Some time in the evening yesterday I finally managed to connect to a group of English learners (they appear to be the only active users of Skypcast these days if I get it right), but after five minutes of me sitting there some weird talkative aussie broke in and scared all the participants off by making fun of them and asking stupid questions. I like one part though… Here’s the short script:
- aussie: … yeah, that’s my name “… Dandy”. You know that Crocodile Dandy? I’m his brother. I wrestle crocodiles.
- one Canadian: well, that’s cool. I wrestle polar bears.
The point is made. Am I missing something or this appears to be a dead branch and isn’t worth monitoring?
For a long time it was a huge pain in the neck to follow the blogs and threads I was ever commenting on. Most of the time I had to make a heart-bleeding decision whether it is going to be a fire-and-forget kind of comment or will I bookmark it somehow for the later returns. I realize everyone has similar problems, otherwise they wouldn’t ask us to add some kind of comments tracking to BlogBridge, so that I’m not alone in these sufferings.
Recently Pito Salas of BlogBridge started a great new series of educational posts on Squidoo. These are intended to bridge the gap between geeky techies chirping with their awful terms, like ‘blogs’, ‘feeds’, ‘rss’ or even scarier stuff, like ‘aggregator’, and simple working bees surfing around.
If you are into SEO, you know how important keywords research phase is. I’m a very newbie in this area and always pay attention to what pro’s suggest. For a couple of weeks, I’ve been using Overture Keywords Inventory and Google External Keyword Tool for my research attempts. They are great tools and they are completely free.
