These are some wild thoughts about Open Source, what it is, and what is should be.

Some trends:

Open source is the new demo

Companies used to make private software, but now they tend to create more open source. Though the open source product is only maintained by the company and is used as a step-up to the paying version.

Take OpenX for example, a package for online advertising. It comes in two flavors: an open source version (the original) and a priced private version. The open source version is far less superior and less maintained than the private. That idea is inherited from the demo-age: a demo was a free version that missed the features to be useful. Today the demo version is licensed as open source, but just because open source is popular.

The open source package isn’t made to be perfect, no, it’s only made to get people warmed up for the paying version. (in terms of OpenX: the open source version has many security holes, which makes it hard to consider).

Open source is company karma

Companies get popular by releasing their open source libraries next to their private software. I may be cynic, but I feel these packages are only made for company karma. A lot of companies sponsor open source projects only to gain karma from the community and eventually sell their services to them.

Because every company wants to have their own open source library, instead of contributing to a library from somebody else, you create a wide field of all sorts of packages that might be abandoned as soon as the company loses interest. The real, well working open source projects are the ones that are supported and used by a wide range of people over a long period of time. These are not the ones that are created because marketing told us so.

I hear you thinking, if private companies want to contribute to open source, why shouldn’t they?

When MySQL was sold to Sun, they didn’t know that Oracle would buy Sun. Widenius, main-developer of MySQL, tried to avoid that Oracle would takeover MySQL at all costs. Right before Oracle bought Sun, he forked MySQL into MariaDB. As soon as Oracle bought MySQL they started adding closed source modules. So there are 2 software packages that are about the same: MySQL owned by Oracle which is partly open and partly closed, and MariaDB owned by Widenius, which is entirely open.

The danger of open source bought or created with private money, is that it might be transformed into closed source software or be taken away from the community. The open source version could be stopped, put on low priority, or be degraded to “demo”.

These moves also cause confusion amongst users. Should they use Open Office or Libre Office? And do they care/know what the difference is? And what about organizations that use an open source package which suddenly transforms into closed source?

The idea behind open source (or community initiatives like Wikipedia or non-technology ones like Transition Network) is: you take from the community, you give to the community. Not necessary in terms of money, but in terms of your skills and your time – whatever your skill may be. Most initiatives need money, so money will be welcomed, but your input is of most importance for the success rate of the project. Wikipedia needs money to run its server and pay its few employees, but even with that money they wouldn’t have made it without the help of all the voluntary writers and readers.

Forks create chaos

The open source community splits into branches. Splitting into branches is a human thing that has been around since the beginning of politics and religion. Splitting up creates quantity but not quality. Just take a look at the discussions about Unity, the new desktop layout of Ubuntu. A part of the community solved it by suggesting another Ubuntu that didn’t implement Unity: Linux Mint. And while Linux Mint is great (I use it daily), why couldn’t we simply agree to stick to Ubuntu and implement the option to disable Unity. It’s open source so it’s possible.

This is where Open Source should make the difference with Microsoft. Microsoft did an equal move by removing the start-button and implementing a dysfunctional desktop (Metro) without any way to “change back to normal” (while Windows users crave for a solution to make their pc’s go faster and don’t care about a new desktop).

Instead of creating one successful well supported product, we create forks, versions that are just slightly different than the original.

All these branches, “doing this different because we believe it’s better” make it impossible to maintain oversight. This is the comparable to Microsoft trying to push their “standards” just for the sake of having an own (in their case: patented) standard.

There are dozens of ways (libraries) to upload a file on a website. If I really want to have the best solution, I have to go to all these projects, demo it or install it. It would be better to have one or two projects that are flexible and well supported by all browsers. Developers just have to learn working with 2 packages and can start working for any employer or follow up any project. It could be taught at school, it could be far more popular and better than any of the dozens of libraries today.

jQuery kind of goes into that direction by creating 1 flexible good javascript library that is wildly supported. But the jQuery-libraries by 3rd party developers make it a mess. There’s no oversight in all these modules, the quality is very different amongst projects, they could conflict with each-other or not be compatible with a new/old version of jQuery.

This is the real pain: “wild” libraries as opposed to “well supported” libraries. This is what gives open initiatives a bad name: the lack of equal quality. Because everybody can create open source, there’s no control, hence no quality assurance.

I am well aware of that contradiction. It’s a debate: do you allow anyone to contribute (democratic) and risk quality instabilities, or do you select the contributors that probably will assure quality but make it less open?

What to do with “bad” contributors/modules?

At my job, an alternative online newspaper, we have a comparable problem. Many of our writers are volunteers, some of them can write good articles, some of them don’t. But what do we do with bad writers? There are 2 schools of thought:

1. We allow bad writers to continue an open democratic website where everyone can report what they want, with the risk that bad articles can harm our quality level (and reputation). Bad writers take a lot of time and effort (it’s more work to rewrite a bad article than to write a good article yourself).

2. We only keep the good writers. That would transform our website into a closed medium and conflict with our basic ideas. By maintaining a high standard we could scare away potential new volunteers who think they’re not good enough but might be.

Keep in mind that some volunteers are bad writers but have interesting things to say. Though, there aren’t enough resources to train every volunteer who fits that category.

We’ve discussed this for hours and it’s hard to figure out a middle way. Currently we have to idea to “star” contributions which we think are good, a quality label. We only want to make that clear with layout changes, because we don’t want to add a textual “warning-this-article-sucks-disclaimer”. That kind of disapproval would make the volunteer displeased, if not angry.

I think that idea would work for Open Source as well, and some of them have started such an idea. Drupal contributors, for example, start with a sandbox project that has to be reviewed by an admin. If your sandbox is alright, it will be transformed into a module. Too bad, too many modules have features that are just slightly different than another. This confuses people: “what module should I use? Google Analytics Integrator? SEO Expert? or just the module named Google Analytics?

The bigger plan is of most importance

Just “starring” doesn’t work if you allow every module by the simple rule that the contributor must be a good coder. There needs to be a bigger plan:

  • What modules do you want?
  • Are the current modules good enough?
  • Which modules should be replaced by better ones?
  • Who wants to manage that?
  • Do we allow everyone to contribute? Or how will we select?
  • Is the project “owned” by a private investor? And do we allow that?
  • How do we collect money in case we need it?
  • How do we get people to contribute?
  • How do we handle requests for certain modules that might not fit our software?
  • Do we risk losing users by not implementing certain features or do we implement everything just for the sake of attracting as many users as possible?
  • Who will decide what to implement? How is that process defined?
  • How do we handle bad content/contributors?
  • Is their a “leader”, someone who pulls the strings? A decision maker? And if not, how do we organize?

I know this comes scarily close to management, but these are questions any serious open project will have to answer some day. It would be a pity if open source projects fail by not thinking these through. These type of questions should be answered for every community project, and not just tech ones.

The reason I think why these questions are left unanswered, is because it’s not a pleasant task and it doesn’t add production value right away. If I spent one week thinking about the questions, I loose one week of coding. And, maybe my time is limited to one week. In case of open source, most contributors are developers. And developers want to develop. They don’t want to waste time on the above questions, no, they want to code, rather now than tomorrow. Many developers, like me, don’t like to “manage”. They get behind their computer, start coding, and hope someone will spontaneously say “hey, can I contribute?”. That someone would be a great coder with the exact state of mind as ourselves, and not some sucker who just created his first html-page.

If I look deeper into myself, the thought that someone would “take over” my project, scares me. That’s perhaps another reason why some questions don’t get answered. If other people involve, I could loose the project, my name in bold on the about-page.

Of all the payed web-projects I left, every now and then, I check back on that site to see how things went on. What did they implement? What did they cut? How did they handle that complex js-problem?

It happens that nothing changed at all: the bug that was reported 5 years ago is still in it, the “temporary” solution has become older than my cat, and the space looks frighteningly… dead. Is this what I created? Did someone forget to turn that server off? Is it all forgotten?

Or, the other side, the project is gone, replaced by something flashy else, dumped on a backup harddisk in a basement.

Luckily, most of the times, the project appears to be in good shape, nice features have been added, developers clearly knew what they were doing. It has been handled respectful. This is what well managed open source projects should become. This is why the questions are important.

I better start thinking about the questions right away but first I want to code that feature that will make the project look awesome.

This tutorial explains how to created a single page with a login form an a register form in Drupal6.


To accomplish this, we have to go through some concepts first:

It felt like a Monday morning. After my alarm clock didn’t get off (+ 1 hour), I noticed there was only a train 1 hour later, so instead of arriving at half past 9, I arrived at 11 and missed the first speaker.

Lightswith + Drupal

Anyhow. I picked up the last quarter of using Drupal together with Lightswitch (= Visual Studio). Apparently not a lot of devs had interest in the subject because there were only 20 people in the room. And those who didn’t attend were right, because all the speaker could tell us was that marrying Drupal and Lightswith could only result in a divorce.

Lightswitch can create a HTML5-admin environment based on a data layer. That data layer could be your Drupal database. Nothing works out the box for Drupal because MS of course wants to integrate their software (SharePoint, Office) and not someone else’s software.

Another downsides of all these MS-Drag-And-Drop-Automatic-Data-Layer-Builder-stuff, is that when you change your database, something on the other side might break and you could end up writing the data layer yourself (as a attendee commented). Plus, the actual html output looks weak and is unusable in a serious professional environment. Don’t try this at work, pro’s!

Drupal 8 discussion panel

Three Belgian core-devs (swentel, Wim Leers, aspilicious) had a one hour Q&A hour about Drupal 8. They all had a lot to tell so the number of actual public questions was limited.

You had to know some Drupal 8 in forehand, because new projects (say WSCCI, PSR or TWIG) were discussed without being explained.

The main message was that Drupal 8 is ready to port your modules to. But, there’s still a lot of work to be done. There are still upcoming API-changes, you can’t translate a node’s title yet and there are various other big and small release blockers. But: Views should be finished. Ah!

And why Drupal 8 should be better that its processors:

  • PSR proof. PSR is a PHP coding standard. (aimed for PSR 4 however, it’s uncertain if it the project will get there)
  • Display Suite is now a core module (however, is this really such a big plus?)
  • Getting rid of the hooks in favor for a more object oriented way (however, hooks still exist)

A post for the Belgians… Drupalcamp 2013 is about to take place this weekend (september 14+15) in Leuven. The whole event is free, however  you have to register and buying a t-shirt is appreciated.

These are some of Saturday’s topics:

You can read the full program on the Drupalcamp website.

I’m getting back at the PHP Laravel framework. I studied most of its documentation and have a decent idea what it can do.

However, I’ve reached at a point where I need a decent “imagecache” functionality, like you have in Drupal. There’s an attempt in Laravel but it doesn’t come close to the easiness of imagecache (probably one of the best Drupal modules).

Further down the road I must have some permission-system, user forms, a comment tool system, Mollom protection, Captcha’s, forgotten-password-mails, newsletter forms, node locking, search integration, OpenGraph, social media toolbars, permalinks and a zillion other features.

The thing is: do I have to reinvent the wheel? Do I even want to do that?

How much time does it take to make a light version of imagecache? If it’s done in half a day it might be worth it. The powerful thing is that I have total control about every little detail. Gone are the days that you can’t get around something because that’s the way it goes in Drupal (eg: must every node-type have a body-field?)

Can I make an opensource CRM/CMS based on Laravel? Ready for others? Is anybody waiting for that?

(for those wondering if I’m wasting someone else’s money, I spend most of my research in my spare time)

Update: I decided to go for it. Things go pretty well so far but, like any IT-project, it’s a lot of work.

Everything! Really!

Drupal 8 changes for developers

Everything will change and certainly for developers

  • The code will be more object oriented,
  • there will be a Symfony-like approach of theming (say goodbye to the _theme() hooks),
  • migrating from local to staging or a live-environment will be easier, as you will be able to save certain local settings in the code,
  • there’s the development project WSCCI (pronounced “Whiskey”) that will give devs the opportunity to write output for json, for apps, or for anything else besides html,
  • the multi-language-approach will be more logical and out of the box (Europe sighs).

In short… you probably won’t be able to reuse a single line of code from Drupal 7 to Drupal 8.

If you want to learn Drupal from scratch, you might want to wait till the release of 8 before you start to study.

Changes for users

For the users the changes are less dramatic, but there’s one big new feature:

  • In-place-editing, found in almost every commercial CMS will finally come to Drupal. This means that when you want to edit a text on a page, you don’t have to press the edit button, find the right field and save, but instead you’ll be able to change text within the normal website layout.

Still a lot of work

But… there’s still a lot of work. Drupal 8 is far from ready. The official release is planned towards the end of 2013, but the date march 2014 is probably more realistic. The in-place-editing for example is currently not working for the title-field, because the title is technically not a field. WSCCI is also far from ready.

Things are even so not-ready that some new features might be cut.


Those who want to contribute or want a sneak preview, can install D8 through GIT. Though, it’s not stable, not even in beta, so don’t use it in a live-environment.

$ git clone --branch 8.x http://git.drupal.org/project/drupal.git

I upgraded my Ubuntu 10.04 to Linux Mint 14. After installing LAMP I got a Drupal WSOD on a previously well working site. As it turned out most errors came from deprecated php-functions and deprecated call by references to functions, introduced with the release of PHP 5.4.

At first I was a somewhat encouraged to solve those deprecated functions, but I gave up pretty soon. Drupal 6 isn’t designed for 5.4. Tweaking Drupal feels the same as upgrading to Drupal 7. Therefor, I keep it to PHP 5.3.

To downgrade 5.4 to 5.3 I recommend this script on the Ubuntu forums.

Introduction (back to the 90’s)

Apple lovers (= those who would kill for a €599 iPhone and trade it for a €20 coupon within two years) have forced webdevelopers to go back to the 90’s. Those phones appear to have 56k modems, can’t play flash videos, and use screens even smaller than 800×600.

If you want to make a mobile version of your Drupal 6 site, you’ll not only have to strip half of your functionality, but also half of your html, css, js, images, flash and anything the w3c recommends since 1989.

I thought in terms of teletext (80’s kids will recall: texts, slow page loading, and low graphical use). (that it is what mobile is).

This post applies when

  • The admin menu suddenly disappears
  • The admin menu is incomplete (menu-items are missing)

Following scenario causes this behaviour:

  • The records of table “menu_links” with menu_name “admin_menu” were deleted (could be caused by an unfinished or erroneous cache wipe).
  • Cache-clear was called and caused a time-out by the webserver or php. (keep in mind cache-clear could’ve been called by cron through wget or by poormanscron)
  • Before the table menu_links was entirely refilled, a page of the website was requested by a user.

Even if you clear-cache afterwards, it says incomplete or missing.

A quick solution I’ve found is this:

  • Backup table “menu_links”
  • Delete the records in the table “menu_links” with menu_name = “admin_menu”. Don’t remove all the records in the table because primary and secondary links are also located in that table and they would be deleted permanently.
    DELETE FROM menu_links WHERE menu_name='admin_menu';
  • Call “cache-clear” but with Drush, because Drush doesn’t get interrupted by time-outs.

Or the more sustainable solution:

  • Change the time-out of the webserver to let’s say 120s.
  • Backup table “menu_links”
  • Delete the records in the table “menu_links” with menu_name = “admin_menu”. Don’t remove all the records in the table because primary and secondary links are also located in that table and they would be deleted permanently.
    DELETE FROM menu_links WHERE menu_name='admin_menu';
  • Call “cache-clear”, preferably with Drush, but you could also call it with the web admin as long as it doesn’t time-out.

It’s difficult to get around Drupal-modules that appear to have the same functionality. This is particularly the case when you want to set-up decent SEO-friendly url’s. The two main modules are called “pathauto” (also named: url-alias) and “path-redirect” (also named: url-redirect). This post applies only to Drupal 6.


pathauto = url-alias = /admin/build/path/list = table url_alias

path-redirect = url-redirect = /admin/build/path-redirect/list = table path_redirect

PathAuto (or URL-alias)

Pathauto is the standard module that creates SEO-friendly URL’s for users, nodes, taxonomy (etc) based on the title of the node. You can set up what the url’s must look like in /admin/build/path/pathauto

But when an url gets changed, the previous url would become unreachable and the user would get a “404 – page not found”-error. This is negative for search engines, bookmarks, and links from other sites. This is where path-redirect comes to the rescue.

Path-Redirect (or URL-redirect)

The path-redirect module keeps a list of all aliases that were changes and redirects them with a 301 (the permanently moved http-status).

In order for this to work, you need to check an checkbox in path-redirect  (see screenshot). Direct link: /admin/build/path-redirect/settings

path-redirect settings for Drupal

As if that ain’t enough, you also have to specify this in PathAuto. Go to: /admin/build/path/pathauto and scroll to “General Settings” > “Update action”. Select “Create a new alias. Redirect from old alias” (see screenshot)
