Re: Now hosted on DigitalOcean

Wed, 6 Jul 2016 10:17:21 -0400

Thanks, that's valuable information in helping me judge what I'll probably need.

Hi Glen, I'm still happy with DO and still using the $10 plan and just one Droplet, which seems to work fine for my (extremely low :-) level of traffic. I'm using 64-bit Ubuntu. - Dave

Re: Now hosted on DigitalOcean

Sat, 2 Jul 2016 17:52:17 -0400

Hi Dave, I'm thinking of switching my blog's hosting provider and have a few questions about Digital Ocean: (1) are you still happy with DO, (2) was it just one droplet necessary to host both the database and ubuntu/Tomcat? (3) through one year, has the $10 plan held up or you found you needed to upgrade to the $20 plan for performance to be acceptable? (4) What server did you choose -- 32bit or 64bit ubuntu or? Thanks! Glen

Re: Doesn't anybody have anything bad to say about Groovy?

Tue, 29 Mar 2016 16:18:43 -0400

It does not have compile time checking, so some idiot error is not caught until runtime. Sure they added a static compile annotation, but at that point why not just use Java. Groovy programmers are not disciplined, so they write sloppy code that looks like VB 6, and Groovy lets them get away from it. It is 2016, and Groovy is still dog slow when compared to Java. Pivotal dropped Groovy, so who is their sponsor now? Not going to bank a corporate information system on some toy project with no corporate sponsors and then find out the devs have given up to focus on "Real Life (TM)" -> which happens to be the lamest excuse to stop supporting a project.

Thanks Amit, that's nice tip. I don't think manual installation will cause any performance problems.

Re: Now hosted on DigitalOcean

There is also one click install app for roller weblog

(just sign in to bitnami, go to launchpad, and install the roller weblog on digital ocean droplet.)

It is easy then manually installation of roller blog on digital ocean,specially new bee like me.

However I don't know , whether it will make performance issue over manual installation or not?

Here is some example code for displaying the tags of an entry:

Re: Usergrid-Vagrant updated for Usergrid 2

Hi Ganesh,

Thanks for the feedback. I just tried to run the VagrantFile on a different computer and it failed to install.

I'll update this issue once I figure out what is wrong:

Hi Dave,

Thank you for the work you have done. I followed the mentioned steps and bring up the application but the authentication fails for superuser and password test.

Re: How to create a Roller 4.0 theme, part 1

Sat, 19 Dec 2015 10:17:53 -0500

Hi Ron, this is a custom theme and I haven't (yet) made it available outside of my blog site.

Re: How to create a Roller 4.0 theme, part 1

Wed, 9 Dec 2015 11:41:48 -0500

I like your theme! Is this theme available to anyone, or is it your own custom theme?

I just added some more detail to the page. Hope it helps.

Hello, I'm trying to install roller-jspwiki-plugin to latest Roller, but not yet succeeded. do you have any plan to add some notes or instruction for in the repository?

Re: New Bootstrap based theme

Tue, 21 Jan 2014 14:13:57 -0500

Thanks Pat. I'll trim down that header images because you're right, nobody is going to see the whole thing. That Expires:0 thing must be a Roller bug.

Re: New Bootstrap based theme

Mon, 20 Jan 2014 21:59:17 -0500

It appears all your images are coming down with Expires: 0 on them, so they will always be reloaded. In addition, the banner image is 2483x420 and 1.7MB. Should resize that to 1000px wide, and you can prolly apply some JPEG compression. Also, it appears the image is clipped anyway, so almost no one is going to see those red leaves on the far right.

This posting is really helpful for who are new to Cassandra.

Thank you for your posting :-D

The code from the old "Roller Support" project is now part of the "Roller Extras" project on Google Code. That's where you can find the source for the Roller Memcache plugin there:

What happened to the install guide you wrote? I can't seem to get roller running on JBoss 6.0.0 or 6.1.0.

[Trackback] Wouldn't you know it, I missed my 10-year blogiversary. 10 years ago yesterday, I wrote my first blog post . This was shortly after reading Dave Johnson's article about Roller . I originally started this blog to share a bunch of tips and tricks I'd...

Re: 10 years ago today

Sun, 3 Jun 2012 06:36:46 -0400

In my knowledge roller is best blogware. I had used roller 3.1 with struts 1.x and roller 4.x with struts 2.x in 2007-2008. I have learned a lot from this blogware.

Re: 10 years ago today

Tue, 8 May 2012 13:47:10 -0400

A 10 year long Time well spent I must say. This kind of product matters larger than any tangible benefit you could get.

Just stopped by to say thanks for all your work you have done so far to make this great.

Re: The future of Project SocialSite: Apache?

Sun, 29 Apr 2012 12:44:25 -0400

Simer, I've given up on trying to get Oracle to donate SocialSite as they promised. If you're interested in OpenSocial-based infrastructure, checkout Apache Rave and Apache Shindig. - Dave

Hey Dave, how is the progress now ?

Re: SocialSite@Apache

Fri, 27 Apr 2012 08:55:18 -0400

That's great Dave. So what's happening with SocialSite now after 3 years ? Is it still in progress ?

Re: The X-rated SocialSite API

Thu, 26 Apr 2012 12:45:35 -0400

Roy Fielding's post is a dictatorial rant showing himself to be petty and egotistical. REST is a great idea, but he should not at all be surprised that many would prefer to cherry pick on his enshrined constraints than wade through pedantic white papers.

There are a lot of broken manuals out there, by his own admission, and he's going to have to accept that his academic dissertation has turned into a buzz word. Just call your API Rest-like, and ignore Fielding.

Re: 10 years ago today

Tue, 17 Apr 2012 16:21:53 -0400

After 2000+ entries on Roller I think I can claim that this is one of the very rare software that has never let me down.

Kudos Dave for all the work and energy you've put into this!

Re: Upgraded to Roller 5.1-dev

Wed, 29 Feb 2012 00:36:36 -0500

It might be possible to integrate Roller with 5.0, but I have never tested it. Your best change of getting an answer is on the Roller mailing lists.

Re: Upgraded to Roller 5.1-dev

Tue, 28 Feb 2012 22:27:12 -0500

Hi Dave, I was trying to figure out how to integrate LDAP with roller 5.0. There's almost no documentation on this. Can you please throw some light on this? I am planning to propose roller as a blogger in our IT organization over here. Thanks for your help.


Re: Comments fixed

Sat, 4 Feb 2012 22:18:53 -0500

Hello, I just installed Roller 5.0 and I'm having an issue with the Fauxcoly Theme. Basically in this theme, if I enable comments for an entry, I get the "Comments are closed for this entry." message. If I switch to the "Brushed metal" theme, the comments are enabled for that entrie. Is this a known issue or do you know how I can fix this?

Re: Obama Administration Comes Out Against SOPA, PIPA

Wed, 18 Jan 2012 19:55:39 -0500

This is just terrible....SOPA is the equivalent of curing a headache with a guillotine. It may stop piracy, but it would shut down our economy and unconstitutionally erode our most basic freedoms in the process.

I just hope that everyone realizes how important this is and does their part to save the internet & our economy! is another good video that explains the consequences of SOPA pretty well:

Re: Fork it all

Sun, 4 Dec 2011 14:56:28 -0500

That is one of my goals, but I don't like the idea of targeting one cloud provider. For now I just want to simplify Roller and drastically reduce the number of modules, dependencies and old legacy stuff that is not fun to work with like Struts and Spring.

Re: Fork it all

Sun, 4 Dec 2011 12:19:04 -0500

So I guess you plan to make cloud-ready version for Roller ;-) Which cloud provider will you target?

Re: Kattare ROCKS!

Thu, 20 Oct 2011 15:05:17 -0400

Kattare have hosted my website for nearly three years in a mixed php/java environment. We have had only two significant outages in the 3 years, and in both cases I was able to reach support quickly and find out what the issue was, and it was quickly resolved. When I cannot reach someone when their offices are closed, I will call the emergency number (when truly needed). In every case someone either answers, or gets back to me within an hour or two (yes, they do not have true 24x7 phone support, but they are on a Linux platform - things seldom go wrong!). Once you reach someone, their service is truly incredible. I am not a programmer, nor do I have a website administrator on staff. Kattare will go out of their way to work through issues with me, including changing my code to close security vulnerabilities when needed. They are never condescending, and will take the time to answer questions when clarification is needed. Having been responsible for several web sites before, their service is the best I have ever experienced. As the COO, it is the best spent $39 a month I have ever authorized. I highly recommend Kattare.

Sounds like a fantastic addition to Roller - great work!

I was lucky to be mentored by Dave.I learned a lot and without his kind guidance it would have been much difficult to me achieve this far.I am really happy that i could contribute to Roller which i am willing to do in the future too.

Thanks a lot.

Tue, 6 Sep 2011 16:58:16 -0400

I apologize in advance for using this form for a contact method in reaching out to you. I couldn't find a way to contact you on this site. I am new to Roller and have been able to find my way around pretty easy. The one thing that has given me a lot of trouble is figuring out how to remove the brackets from around the read more links.

I tried to edit them out of the weblog.vm file located inside the 'deprecated' folder, however this is not reflected in the system.
Could you please point me in the right direction.

I really appreciate any feedback you may provide.
