rolling back changes with revert

We’ve all done it. Perhaps you didn’t have enough coffee that morning, or it was just before lunch. Somehow though, that bug got into the repository, and now you need to get it out. Luckily, git revert is just the scalpel you need to extract that bad commit.

Let’s say our history looks like this:

Storing Your Files

This is the second article in my series on file management, the third article will cover the challenges of handling uploads then we should be able to move on to some more advanced topics.

The second problem you’ll face when building an application to handle files is where and how to store them. Thankfully there are lots of well-supported options, each with their own pros and cons.

55 minute video: Flex on Rails presentation at RMAUG on March 10th

This is the edited version of the talk Tony Hillerson and Daniel Wanja gave at the Rocky Mountain Adobe User Group on March 10th. There is an echo the first two minutes, then the sounds stabilize. We also had a software issue on Tony's notebook and display port issue on Daniel's, parts which I edited out. The demo gods where not with us that night :-), but we had fun and I hope we answered many of the questions the attendance had.

poetic tweets

Saul Williams’ trek through the midwest between shows sparked some musings on Twitter.

Driving from Denver to Kansas City. My mind travels at a faster pace than my body. I mark my way with words. If the newest technology enhances transparancy then this is an ideal time to share your process. Share how your mind works. How do you think?

Rails Envy Podcast - Episode #070: 03/13/2009

Episode 70. I was going to try and copy Gregg from last week but my dog can't talk yet to do the introduction. Darn obedience classes. Obie Fernandez from Hashrocket co-hosts this week and we have a blast. I hope you all enjoy the show and am sorry for the delay. But it's a good one, I promise!

WTF does that cron do?

I’ll be the first to admit that I’m not a great system administrator. I was a windows guy for so long, so my only exposure to linux was haggling with shared hosting accounts to run my stupid php apps. While my linux/administration skills have grown by leaps and bounds in the last few years, I still get caught up on something as simple as cron jobs. The syntax is very terse, and probably easy to parse for computers. For the rest of us… Well, what the hell does this mean?

Moves login redesign

Just a quick post. Since our annual fair is coming up next week I decided the Moves login screen could use some new paint. I also added a banner to clearly indicate the demo versions we have running. I just wanted to share the images and see what you guys think!

ActiveRecord + sqlite + in memory db + without rails

For a current data crunching project I’m working on, it makes sense to build a db in memory at the moment. Doing it in memory allowed me to cut the run time by about 75%. I’m sure I could get it down further, but atm this is good enough, and was v. easy to setup.

I started with a yaml config file, probably unnecessary, but I have some other db configs in there too, so makes sense for me.

What's coming on Github: 5 Projects to watch

Ruby Inside does a sort-of monthly “What’s hot on github” post, but the rate of new projects is starting to make it feel somewhat lethargic.

So, I’m going to start doing a somewhat more regular series. Here’s 5 for the next few days:

Ignite RailsConf – Pre-Conference Lightning Talks on June 6, 2010 | Rails Fire

Ignite RailsConf – Pre-Conference Lightning Talks on June 6, 2010

Send to friend

ignitebaltimore.pngBaltimore's Rails community is welcoming this year's RailsConf with an un-official pre-party the evening before RailsConf begins: Ignite RailsConf. Ignite events are lightning talks, where 16 speakers each get 5 minutes to talk about a subject they are passionate about, but with a twist: the speaker's slides are automatically advanced every 15 seconds. Ignite's motto is "enlighten us, but be quick about it!"

Ignite kicks off on June 6, 2010 at 6 pm at the Sheraton Inner Harbor, which is connected to the convention center where RailsConf is taking place. You can register to attend at this link. Tickets are $5, and all proceeds after expenses will benefit a Ruby-related charity or project (if you would like to suggest a charity please email mike@subelsky.com).

We're looking for a wide range of talks, which you can propose here. Not all of the talks will be Rails-specific but all will be of interest to Rails developers. (One ideal talk would be a version of Geoffrey Grosenbach's recent What Pythonistas Think of Ruby post). You do not have to be a RailsConf attendee to attend or speak at the event.

We are looking for a few more sponsors to help defray the cost of renting the space and providing food and videography. So far we have received generous sponsor commitments from NewRelic, Hashrocket, Peepcode, Smartlogic, and Intridea. If you are interested in sponsoring, please email mike@subelsky.com.
