HabitRPG and Remember the Milk Synchronization on the Command-Line

If you, like me, are a user of both HabitRPG and Remember the Milk, you may have been looking for a way to link the two. I developed habitrpg-todo-sync (HabitRPG Todo Synchronization) to do just that.

The README file explains in good detail how to use it.

Come on, just tell me how to use it

OK, here’s the quick version (you need NPM installed, which you get with Node.js):

npm install -g habitrpg-todo-sync

habitsync

It will tell you what to do from there.

Full synchronization

You might be interested in running

habitsync -a

to do a full synchronization of your tasks. By default, it only retrieves the last week of them.

Don’t synchronize everything

You may not want to get all your tasks. habitrpg-todo-sync can make use of Remember the Milk’s advanced search interface (ever tried typing something like addedWithin: 1 week ago in their search box?). Here’s how:

habitsync –filter=”list:Name of Your List”

You can do anything you can do with their interface.

And you can combine command-line options:

habitsync -a –filter=”list:Smart List You Want To Sync”

Run on a schedule

You can run it manually or add it to cron. I have this in my crontab, which runs it every hour against beta.habitrpg.com (which is often more likely to be working). To put it in yours, you generally run

crontab -e

and then add the following line:

# min hour mday month wday command
*/60 * * * * /usr/local/bin/habitsync -qB

You can separate each argument with spaces or tabs, and you don’t need the first line. I just included it for completeness.

It doesn’t do what I want.

Tell me! I really want to hear back from users of it. When I don’t, I assume nobody cares, and I improve it much more slowly. Report issues on GitHub.

DrupalCamp alert: DrupalCamp Gothenburg 2013!

If you haven’t been following any of the calendars listing DrupalCamps, you may have missed the arrangement that’s coming up in Gothenburg, Sweden in a couple weeks. This wouldn’t be surprising, since it’s being marketed in Swedish. People of all languages are welcome, however, so I thought I’d somewhat rehash the post I made in Norwegian.

The camp’s pitch is: “A one-day conference focused on the Drupal CMS. Come along and learn more about Drupal and the web, and have a great day in Gothenburg in late Spring.”

Sessions are here: http://summer2013.drupalcamp.se/program/sessions

As with most DrupalCamp sites, volunteer work lies behind the site you see. A lot of people contributed really great work. Fantastic designs and solid development resulted in the site you see today. I was also involved, mostly behind the scenes. I helped with server administration, Git coordination, transferring the site to another server, and mostly with coordinating the web team’s efforts. It was the first time I had spent as much time helping organize a DrupalCamp (and I’ve been to quite a few; I’ve even volunteered at a couple).

If you’re in Europe or in the area, I encourage you to check it out. You can follow them on Twitter at @DrupalGBG.

Google Translate is getting better and better 🙂

One SSH key to rule them all: Forward your SSH agent session in 15 seconds

Recently, I used a tool that spoke of “forwarding” my SSH session to the server and thus avoiding needing to copy my private key to the server in order to be able to access Git repositories or other servers where I log in by public key.

If you manage your keys at all, you can immediately see the allure here.

The configuration is ridiculously easy. Put this in your $HOME/.ssh/config file* (Windows users, check PuTTY settings; it can probably do this too).

Host <hostname>

ForwardAgent yes

You can, of course, combine this with other options such as HostName and User.

I tested it with Fill PDF Service:

Host fps

HostName fillpdf-service.com

User myusername

ForwardAgent yes

ssh fps
cd /path/to/my/web/root
git pull

(The Git repository is password-protected, and my Git setup uses SSH for authentication by default.)

I got back: Already up to date.

I used to be prompted for my password, but that’s yesterday’s news…quite literally.

Extra tip: If no one else uses your computer, you can put ForwardAgent yes on its own line. This will forward your agent to all servers you connect to. I’m not an SSH expert, but as far as I know, ssh-agent is designed to be extremely secure. The main risk is if someone is using your computer directly, but that applies to most things. SSH Agent sessions are restricted to the current user session via environment variables (so no one can simply switch to you on a server to get access).

It blew me away how easy it is to get this going. 2013 is the year of SSH agent forwarding for me. Hope this helps!

* If the file doesn’t exist, create it. Make sure the permissions on the .ssh directory are 600 (drwx——).

Klar for å ta oppdrag i Norge! (Now open for business in Norway!)

WizOne Solutions has moved to Norway! You’ll see a slight update in the footer showing its Norwegian organization number. The official new name is Kaland Web, but we will continue being WizOne Solutions. A Norwegian version of the site is likely to show up after a while. In short: I haven’t blogged in a while, but I’m still here!

Rates on new work will generally be consistent with the Norwegian economy, so that is something to keep in mind when evaluating my services.

Looking forward to seeing how this new chapter unfolds!

Norwegian speakers only beyond this point:

Kjære norskspråkelig menneske :),

Jeg snakker norsk, så bare ta kontakt direkte på norsk hvis du har behov for tjenestene mine. Jeg kommer ikke til å skrive så mye på norsk på denne bloggen. Jeg vil heller ha en helnorsk side enn å blande språkene. På Twitter kan du sende tviter til @wizoneno eller @wizonesolutions.

Git: Rebase workflow with remotes involved

Note: I haven’t gone to great pains to make this post beginner-friendly, but if you’re in my situation, you should be able to follow along and understand the problem and how I solve it. Feedback welcome in the comments.

Overview

I’ve been trying to stick strictly to a rebase workflow in Git, rather than using git merge.

This has not been without it perils.

However, I’ve found a workflow that works for me as an individual developer using my own feature branch that I push to a remote. Do not use the following workflow for other situations unless you know what you’re doing.

“Why are you doing this?” and such

The problem: After rebasing using the mainline as a base (git rebase master) you can no longer push the rebased branch to a remote since it won’t fast-forward anymore.

Why would you push it to a remote? Because you have untracked/dirty files that need to stay that way locally. In my case, my Drupal settings.php is in the repository – don’t blame me, I don’t control the client’s internal processes – and it must stay dirty for my local site to function. Rebasing is much easier when you don’t have to worry about such files, though, so I keep a second clone of the repository that I use for rebasing.

Pushing my changes from the dirty repository works fine, naturally, since I don’t rebase there.

But once I rebase in the clean repository, how do I push those changes back to the dirty one without causing a merge?

It actually only takes a few commands, and it is pretty safe as long as everything you want to commit to your feature branch is already committed.

The good part (commands!)

This is what I do:

cd /path/to/clean/repository/clone

git pull (remember, I don’t work on this repository, so it will always fast-forward)

git checkout featurebranch

git rebase master

(fix any conflicts and complete the rebase)

git push -f origin featurebranch (this overwrites the remote with what I now have)

cd /path/to/dirty/repository/clone

git checkout master

git branch -D featurebranch (this deletes the local featurebranch branch)

git checkout featurebranch (you may have to use git checkout -b featurebranch origin/featurebranch – I don’t know what differentiates if you have to or not)

Explanation and conclusion

So basically, I’m recreating the local branch from the remote branch. Then I continue developing and rinse/repeat when I need to integrate changes from the mainline or when I’m done with my feature and want to make sure it will fast-forward into the mainline. I finally developed this workflow after finding I always had to merge my feature branch into the mainline in the end; it would never fast-forward. This is because I was running git rebase origin/featurebranch from within the feature branch, since then it would let me push. This basically defeated the purpose of rebasing since it would rebase the new commits from the mainline on top of mine. I wanted mine on top of the new mainline commits.

Hope this helps some poor soul out there who’s in the same boat I was.

VirtualBox 4.1.18: How to solve “Failed to load unit ‘HGCM’ (VERR_SSM_UNEXPECTED_DATA)”

(Update 7/18/2012: My theme cuts off the title. The full title is, “VirtualBox 4.1.18: How to solve “Failed to load unit ‘HGCM’ (VERR_SSM_UNEXPECTED_DATA)”.)

So, this is a bit of a departure from my usual type of post, but it’s still DevOps-related (an area I’m increasingly getting into), and people are probably searching for this.

My experience with this error

I had to send in my Windows laptop for warranty repair, and I was running a couple work-critical VirtualBox virtual machines (“VMs”) on it. I use Vagrant to run them without a GUI, and moving them was easy. I used vagrant package, copied over the project files, and ran vagrant up on the destination machine. This was not the issue.

I got this error when I suspended the virtual machines, then tried to resume them

So for some reason the VMs started up without issue. However, upon suspend and resume, I started getting the titular error. I searched for it on the Internet and found a VirtualBox forum which linked to a bug report which suggested editing the .vbox file. This is in <home directory>/VirtualBox VMs/<name of VM> and is named after the VM as well. It ends in .vbox.

Now, before you edit it, make sure you:

  1. Suspend or shut down all running VMs
  2. Close VirtualBox

If you don’t, this won’t work because VirtualBox will use the previous configuration anyway.

OK, so open up the .vbox file. Search for SharedFolders. You will see something like:

<SharedFolders>
<SharedFolder blah blah blah />
</SharedFolders>

Anywhere in the file you see that, change it simply to:

<SharedFolders/>

and save the file.

Now open VirtualBox and try resuming the afflicted VM again.  It should work. If it doesn’t, go check the .vbox file and make sure VirtualBox didn’t change it back. If it did…then make sure you followed the two preparatory steps above. I’m speaking from experience here. You can’t skip those.

And you’ll be good!

Update (7/17/2012): If you have several VMs that you run together, sometimes one of them will resume while the others fail with this error. If you resume that one, you may be able to subsequently resume the others. Not sure why this happens since the VM in question didn’t have any VirtualBox shared folders (not even in the XML), though some were using NFS. Perhaps it was internal-network related. Just noting this here since it happened.

My mobile office is now in the Toolbox

If you follow me on Twitter, you probably already know all this. If not, however, allow me to explain.

When I’m away from home, whether at a cafe or a Drupal event, there are a few things I take with me to ensure a pleasant working experience. You may have encountered me with them at a Drupal event. I’ve had the setup since SANDcamp 2012 and also had it with me at DrupalCamp NJ, DrupalCamp Twin Cities, and DrupalCamp Sacramento.

These tools definitely increase my productivity (hint: one is a USB-powered monitor that you can carry around!).

So, without further delay, check out my mobile office!

I’m a mentor at the free DrupalCamp Sacramento training on June 8!

I haven’t been blogging enough recently, but I will try to keep you posted with short updates at least. It’s been a busy first quarter of the year!

But I wanted to post to announce that I’m mentoring this training, which as I write is tomorrow. It’s full, so this is sure to be an interesting experience on my part. BuildAModule.com’s site is here (affiliate link).
