KnackForge: Displaying Webform submission data in Drupal Views

mar, 26/08/2014 - 19:50

Although Webform module comes with limited integration to expose the submitted data in Views, it lacks the fine control to make View by Webform field as rows and columns. There is a workaround to achieve this though which I would like to briefly run through in this blog.

Webform MySQL Views together with Data and Schema modules with a patch to Webform MySQL Views from issue #889306: Allow the designation of a primary key for MySQL views makes this feasible.

Webform MySQL Views, as the name implies, allow us to create MySQL view from Drupal, leveraging the Data module which counts on Schema module.

Data module wraps a bundle of sub-modules, among them Data Search provides Views Integration and Data Admin UI for accessing its administrative pages.

Once the mentioned modules are enabled. You can see a sub-menu "MySQL Views" under Administration » Content » Webforms. Tick the Webform node whose fields are needed in Views. This form is only meant to create MySQL view.

Drupal Association News: Announcing the New Drupal Jobs Career Site

mar, 26/08/2014 - 17:13

Today we’re proud to announce the launch of Drupal Jobs, a career site dedicated completely to Drupal. The Drupal job market is hot (more on that in a moment) and we hope this new tool will help match the right talent with the right positions.

For job seekers, you can start searching for positions by location, position, skill level and more. You can create a profile with your job preferences and salary requirements, and even choose whether you wish to be contacted by employers and recruiters. All for free.

For employers and recruiters there are a variety of packages available, giving them the opportunity to highlight their company with a branded page and feature select postings in newsletters and social media. The great thing is that proceeds from postings are invested back into Drupal.org and its subsites (including Drupal Jobs) and community programs.

The website is launching today and, as with any new website, we expect there will be some kinks to work out. But we know Drupal Jobs will be a valuable addition to the current options for employers, recruiters and job seekers.

The Drupal job market shows no signs of slowing. Our recently conducted survey points to a strong need for talent (see the chart below). In the next few days we’ll publish the full results of the survey. In the meantime, check out Drupal Jobs and let us know what you think.

Palantir: D8FTW: Your Next Drupal Hire Isn't a Drupal Hire

mar, 26/08/2014 - 16:17

One challenge the Drupal community has faced for some time is a labor shortage. There are, quite simply, not enough skilled Drupal developers to go around. That's quite a problem when the Drupal market is continuing to grow steadily.

One of the challenges to finding good Drupal talent is that Drupal has historically been, well, weird. And by "weird" I mean "entirely unlike any other system on the market". That makes few skills transferrable between Drupal and any other PHP framework, application, or system. Developers trained on Drupal cannot easily transition to any other system and developers trained on any other modern PHP system get lost in arrays the minute they set foot in the door. It's a sufficiently large problem that I've talked to other development shop owners that have said outright they have more success hiring fresh, junior developers and training them on Drupal as their first system than hiring anyone with experience, as those with more extensive PHP experience run for the door.

That's a big problem. Fortunately, that's about to change.

For the past several years, the Drupal project has been working to Get Off the Island. Drupal 8 will be using more standard, common PHP and programming-in-general tools, techniques, and architectures, making it more accessible to more developers than ever before, even non-PHP developers. The number of Drupal developers showing up at non-Drupal events is rising; For example, Lonestar PHP 2013 had two; Lonestar PHP 2014 had 10 (which for a 200 person conference is a very respectable number). I've noticed similar trends at other PHP conferences.

But to really seal the deal and help fill the Drupal employment gap, it's time for Drupal employers to step and do their part: Selling off the island.

With Drupal 8, and the buzz around it in the general PHP community, there will be an increasing number of general PHP developers interested in working with Drupal and who are better qualified to work on Drupal. (Not with no training, but with far less retraining than Drupal 7 requires.) Those developers, though, won't just walk in the door. They have no reason to come to a DrupalCamp, and probably not even a DrupalCon. As a Drupal consultancy or Drupal-based company you need to go out and find them. The core team has done its part, now it's time to do yours.

A friend of mine once said that if you want to meet people with whom you have a shared interest you need to go where people with that interest hang out. That applies for hiring, too. So where does the next round of Drupal talent hang out? At non-Drupal events. If you don't then someone else will hire the next generation of senior developers before you do.

  • Have a presence at events: Ensure that your employees aren't just going to Drupal Camps. Make sure that some of them go to general PHP or general Javascript conferences, too. Not only is is good professional development for them (which makes them stronger developers and therefore stronger members of your team) it's good advertising for you. The word-of-mouth impact of knowing one or two smart, friendly people at "that Drupal shop" greatly helps when someone is looking for a new challenge.
  • Have a presence on stage: Make no mistake, presenting is hard work. It takes a lot of preparation to give a good talk, and that takes time. But the impact of having someone from your company on-stage is 10x that of having them walking around the hallway with other attendees. If someone from your team can present on work that you've done that's fantastic. But even just presenting on something cool, interesting, insightful, or otherwise useful can be a big help to your company's brand. Also, light branding of the presentation itself is completely OK as long as it's not gratuitous. That's a much more targeted form of marketing than exists anywhere else, online or off; you have a self-selecting group of potential hires in one room together. Let your team be what they're there to see.
  • Sponsor: Drupal shops sponsor events all the time. Every DrupalCon and DrupalCamp has a long list of sponsors that help make the event happen and many of those have a physical presence as well with a table or booth. Sure, that is in part to help support the community and it should be commended. But let's be honest, few companies are going to sponsor an event unless they think the marketing value of it is a good return. Clearly, many companies do think it's a good return because they keep doing it. Why should the return be any different at a non-Drupal event? Historically it's been lower because Drupal was so isolated from the rest of the PHP world but that's changing. Sponsoring a general PHP, Javascript, or web developer conference is becoming just as useful a marketing endeavor as sponsoring a Drupal-specific event.

At the start of 2013 I laid out a challenge to Drupal developers: Attend at least two non-Drupal events that year. I'll now lay the same challenge out to Drupal-based companies: Encourage your team to present at at least two non-Drupal events in the next year, and sponsor at least two non-Drupal events in the next year. There's no shortage of them; there's over a dozen PHP conferences just in the USA every year and more around the world.

Your next Drupal hire is going to come from a non-Drupal background, especially a senior-level developer. If you want to hire them before someone else does, get out to where they are. It's a whole new market if you're willing to embrace it.

ComputerMinds.co.uk: Contribute to Drupal(.org)!

mar, 26/08/2014 - 14:00

So at DrupalCon Austin I had a great time at the contribution sprints. I worked on some issues affecting Drupal.org, it was great fun!

The issues we worked on over the week range from simple things through to some pretty difficult issues.

Although Drupal core can always use more contributors, I would suggest that Drupal.org is also desperately short of contributors too.

KnackForge: Drupal 7: Invoking custom callback in maintenance mode

mar, 26/08/2014 - 13:10
In a Drupal site, if we have any module upgrade or configuration related work to be done in our live site, it is recommended to put the site in maintenance mode, so we can prevent end users from experiencing glitches.   When the site is operating in maintenance mode, any page request would return only maintenance message. Some pages are allowed to access though. The login functionality for instance will work in the maintenance mode. Recently, I faced such a requirements in which a custom module's callback to be invoked as to let Single Sign On (SSO) work for admin in maintenance mode. I would like to explain the way I fixed the same in this blog.   There is a hook in Drupal 7 for that, hook_menu_site_status_alter(). With this hook we can control the site status before menu dispatching, So we can change the site status for the particular path.

Dries Buytaert: Open Source and social capital

mar, 26/08/2014 - 10:27
Topic: Drupal

The notion that people contributing to Open Source don't get paid is false. Contributors to Open Source are compensated for their labor; not always with financial capital (i.e. a paycheck) but certainly with social capital. Social capital is a rather vague and intangible concept so let me give some examples. If you know someone at a company where you are applying for a job and this connection helps you get that job, you have used social capital. Or if you got a lead or a business opportunity through your network, you have used social capital. Or when you fall on hard times and you rely on friends for emotional support, you're also using social capital.

The term "social" refers to the fact that the resources are not personal assets; no single person owns them. Instead, the resources are in the network of relationships. Too many people believe that success in life is based on the individual, and that if you do not have success in life, there is no one to blame but yourself. The truth is that individuals who build and use social capital get better jobs, better pay, faster promotions and are more effective compared to peers who are not tapping the power of social capital. As shown in the examples, social capital also translates into happiness and well-being.

Most Open Source contributors benefit from social capital but may not have stopped to think about it, or may not value it appropriately. Most of us in the Open Source world have made friendships for life, have landed jobs because of our contributions, others have started businesses together, and for others it has provided an important sense of purpose. Once you become attuned to spotting social capital being leveraged, you see it everywhere, every day. I could literally write a book filled with hundreds of stories about how contributing to Open Source changed people's lives -- I love hearing these stories.

Social capital is a big deal; it is worth understanding, worth talking about, and worth investing in. It is key to achieving personal success, business success and even happiness.

Drupal Association News: Drupal Association Board Meeting: 20 August 2014

mar, 26/08/2014 - 01:46

We held our most recent monthly board meeting last Wednesday, 20 August and we had a lot of news to report and a big agenda to cover. You can review the materials or check out the recording

As the year continues to progress, our momentum as a team continues to build. We're accomplishing more and more with the community, which is fantastic to see. That said, it's also been a challenging year. This is the first year we have attempted to systematically measure the impact of our work. On the one hand, it's been wonderful to start to accumulate a baseline of data we can measure against for the future. On the other hand, the data is also a little all over the place. In some cases, we had very little to go on when setting the goals, which means that we aimed way too high or low. In other places, we have some areas of real concern to address. 

Here the topics we tackled on Wednesday:

Drupal.org Improvments

Overall, we've begun to see some significant improvements to the stability and performance of Drupal.org. Although many of our metrics related to performance are still in the red for the year, the last few months have seen significant improvements in page load times, etc. In short, things ARE getting better. Additionally, as the tech team has begun to gel under new CTO Josh Mitchell's leadership, they have begun to rapidly turn out great work on the feature side of Drupal.org. We've tackled a remarkable number of issues in just the last few months:

  • Implemented user pictures on Drupal.org profiles
  • Conducted 30 User Research interviews and began developing personas for a skill acquisition model of user design (more to come from the DCWG)
  • Implemented RESTws API for Drupal.org
  • Implemented Semantic Versioning for Drupal 8
  • Added Supporting Organizations field on projects (entity reference to an organization with an explanation field - we need to promote this change as it was part of the overall efforts to give credit to organizations)
  • Took over maintenance of the PIFT and PFFR testbots so that the community could continue with improvements to a modern, best-practice alternative
  • Updated the Bakery module to allow us to better integrate with subsites like Drupal Jobs
  • Responded to spam on several subsites where the basic Mollom configurations were overwhelmed by human spammers
  • Responded to and deployed several security release updates including the recent XMLRPC response where we teamed up with WordPress
  • Launched a new landing page on Drupal.org for designers and front-end developers
  • Automated process for publishing supporting partners on Drupal.org

Although Drupal.org is chock full of data, this is an area where we had very little longitudinal or granular data to guide our goal setting. Combined with our slow hiring cycle, we've had a tough time really making a dent in some of our red numbers, but we ARE making progress and most importantly will know so much more for next year than we did for this year. 

DrupalCons

We shared a very in-depth review of DrupalCon Austin at this board meeting, as well as trends for Amsterdam. The long and short is that we had, in almost every way, a very successful DrupalCon in Texas. We were able to compare evaluation, finance, and attendance numbers to Portland and show our year over year trends, which was very helpful. While there is a lot to be happy about, we also have reason for concern. While DrupalCons have sustained growth year over year since their beginning, Texas was basically flat compared to Portland in terms of attendees. Looking ahead at the Amsterdam numbers, we're also finding that we may be at or slightly below our Prague numbers. 

There are many reason we could be seeing a plateauing of these numbers. It could be a natural by product of where we are in the product development cycle. No Drupal 8 and a really mature Drupal 7 product means there is less to talk about and learn. It may be that our demographics are shifting and the Con is not needing their needs. It may be a combination of many things. 

What we DO know is that we need to get to the bottom of the issue so that we can adjust our strategy accordingly. After Amsterdam, you will see a survey from the Association to help understand your DrupalCon motivations. So whether you've always gone to DrupalCon or have never entertained the notion, we will want to hear from you.

Licensing Issues on Drupal.org

I've heard from lots of volunteers on Drupal.org recently that our policies for enforcing GPL v2 licensing on Drupal.org have been problematic. In short, there are too many issues, those issues are reported inconsistently, and volunteers are not trained on our licensing issues and apply remediation to those issues inconsistently. It's a pretty typical story - great volunteers getting stuck in an escalating situation. 

To help mitigate these issues, I pulled together a call with folks who had been working on these issues for advice about how we can help fix the process. The advice of the group is to form a Licensing team (like the Security Team), that receives training from the Association's lawyers and works together to resolve licensing issues quickly and consistently. We would create a separate queue for licensing issues and get this off the plates of the webmasters queue volunteers (where most issues end up now). 

The board agreed that this woudl be the logical next step and a meeting has been scheduled for September 9th to begin work on a charter for the group.  We'll share more details as we have them.

Quarterly Financials

Finally, in executive session we reviewed and approved the financials for the second quarter of 2014. Here they are:

Next Meeting

The next board meeting was scheduled for 17 September 2014. However, given the proximity to the 3 October board meeting at DrupalCon Amsterdam, the board decided to cancel that meeting. Remember though, you can always review the minutes and meeting materials in the public GDrive

Lullabot: Module Monday: Office Hours

lun, 25/08/2014 - 15:00

Lets say you are building a site for an institution with multiple locations, each of which have varying hours depending on time of year or other variables. What is the best way to manage this data? This is a pretty common type of content modeling problem. The easiest thing to do is to just give each location a text field for their hours, but that limits display options and is prone to data entry errors. You could also build out a whole fancy content type with multi-instance date fields, but that could get bloated and difficult to maintain pretty quickly.

Friendly Machine: Web Performance: A Guide to Building Fast Drupal Websites

lun, 25/08/2014 - 00:50

What follows is part one in a series of posts on web performance that I've wanted to write for quite some time. In this series of posts I'll not only be talking about optimizing web performance generally, but also providing specific guidance for speeding up Drupal sites.

Although I'm not a web performance specialist or expert, I have taken a keen interest in the topic in my work as a frontend developer building responsive websites. I love building fast sites and have gained some experience over the years getting Drupal to shed some its inherent sluggishness. 

As a way of systematically tackling what can be a complex subject, we'll use the results of a test from WebPageTest.org, a Google-sponsored tool that provides very in-depth information about the performance of a site in nice, easily digestible chunks.

How Fast Is Fast Enough?

Before we get into the details of web performance we should first stop to ask how fast a site should be in order to qualify as "fast". Here are some research results courtesy of Radware that might help bring things into focus:

  • 64% of smartphone users expect pages to load in less than 4 seconds.
  • The performance poverty line (i.e. the plateau at which your website’s load time ceases to matter because you’ve hit close to rock bottom in terms of business metrics) for most sites is around 8 seconds.

More guidance comes courtesy of Ilya Grigorek of Google. In his recent presentation at the Velocity conference, he cited research that indicates a target page render time should be 1000ms - or one second  - to avoid "context switching" among users.

Basically, if it takes a page longer than one second to render, you risk losing the attention of the user. If it takes longer than eight seconds for a page to render, it's similar in terms of business metrics (conversions, sales, etc) as if it took 30 seconds or a minute.

If one second sounds impossibly ambitious, there is further research showing that a load time of three seconds or less is probably OK

The bottom line: your pages should load in under three seconds on desktop, and under 4 seconds on a mobile.

Pretty harsh reality check, huh? Let's see what can be done to get our sites whipped into shape.

Test Results for this Analysis

In order for us to have a practical example for our discussion, I ran the Friendly Machine site through WebPageTest. Here are the results (click to enlarge image):

I recently completed a refresh of the design of this site with a lot of attention focused on keeping things fast. My target page load time was one second, so I was happy when the results consistently came in below that.

Let's start our analysis by looking at the first number in the above table - under the heading "Load Time". You'll see the value is 0.662 seconds. That's pretty darn good, but if you scan across the table you may see something on the far right that's a bit confusing - a Fully Loaded Time of 0.761 seconds.

So what's the difference between Load Time and Fully Loaded Time?

Load Time is calculated from the time when the user started navigating to the page until the Document Complete event is fired. The Document Complete event is fired by the browser once the page has completed loading.

The Fully Loaded time, on the other hand, also includes any metrics up until there is no network activity for two seconds. Most of the time this means watching for things being loaded by JavaScript in the background.

First Byte Time = Backend Performance

Whenever talk turns to web performance, it seems a lot of folks immediately start thinking of what's happening on the server. Although it's a very important piece of the puzzle, as we walk through this analysis, you'll see that most web performance issues actually reside on the frontend.

Before we get ahead of ourselves, though, let's return to the results from our test and look at the next metric in our table, First Byte Time (highlighted in blue below) which tells us about performance on the server.

This First Byte Time represents the time from when a user began navigating to the page until the first bit of the server response arrived at the browser. The target time for this on WebPageTest is a meager 87 ms!

This metric is also represented as the first in the series of letter grades you see at the top of the test results. You'll notice Friendly Machine got an "A" and I really wish I could take credit for it, but the truth is my host Pantheon - and the awesome backend performance they provide - are responsible for this metric scoring well.

Backend Drupal Performance

Let's pause here and talk specifically about backend Drupal performance. How would we address this metric if it hadn't scored well? This topic can get pretty deep, so we'll only review the most popular options, but they'll still be able to do wonders for improving this key metric if your site is not performing well.

Let's start by discussing server resources (with a brief, tangential mini-rant about shared hosting).

If you want a fast Drupal website, you really shouldn't be on a shared host, period. Although many of them will claim to be Drupal specialists, very few of them actually are. One giveaway is the number for PHP memory limit.

Although this number doesn't directly impact performance, it can break your site if it's too low and is also useful for smoking out hosts that don't know Drupal. You can find this number at admin/reports/status and it will look something like the image below.

You can see on my site this number is at 256 megabytes and this is most likely where you want it, although if you have a simple site without Views or Panels, then 128M might work. If it's set at 64M, then it's too low and this is often what you'll find with shared hosting arrangements. 

Another issue with shared hosting - and one that does impact performance - is that your website is on a server with perhaps hundreds of other sites. If one of those sites gets hit with a large spike in traffic or some other issue, it can affect all the sites on that server as it gobbles up the available resources.

Perhaps the biggest issue with shared hosting, however, is that advanced caching using tools like Memcached and Varnish are rarely, if ever, available. And when it comes to Drupal backend performance, caching is critical. The best you'll probably be able to do with regard to caching on shared hosting is using the Boost module, which we'll talk about in the next section.

To ensure that server resources aren't an issue for your website, consider either a managed VPS or a Drupal host like Pantheon, both of which start at around $25 per month. Pantheon is what I recommend for small to medium sized sites because your site will scale better with them and they offer tremendous value, although they are a great fit for enterprise clients as well. If you have a bigger budget, Acquia or BlackMesh might fit the bill.

Sure, these options cost more than the $7 per month the cheap hosts offer, but they will provide a professional level of service that will more than pay for itself over time.

Caching for Drupal Websites

We said caching was critical, so here are five of the most important caching solutions for a Drupal website:

  1. Drupal's built-in caching
  2. Boost module
  3. Memcached
  4. Varnish
  5. Views caching

There are other options, of course, but these five cover most of the ground. Let's briefly go through them one at a time.

Drupal's Built-in Caching

Most of a Drupal site is stored in the database - nodes, information about blocks, etc. - and enabling the default caching will store the results of these database queries so that they aren't executed every time a page is requested. Enabling these settings alone can have a big impact on performance, particularly if your pages use a lot of views. This one is kind of a no-brainer.

Boost Module

The Boost module is pretty great. It works very well in tandem with Drupal caching, but it requires some additional configuration. What you end up with after you have the module installed and configured is a caching system that stores the output of your Drupal site as static HTML pages. This takes PHP processing out of the equation, leading to another nice bump in performance.

Memcached

Memcached can speed up dynamic applications (like Drupal) by storing objects in memory. With Boost and Drupal caching, the data being cached is stored on the server's hard drive. With memcached, it's being stored in memory, something that greatly speeds up the response time for a request. Memcached works great in conjunction with both Boost and Drupal caching.

Varnish

Varnish is an HTTP accelerator that, similar to memcached, stores data in memory. It's capable of serving pages much faster than Apache (the most common web server for Drupal sites). It can also be used in conjunction with memcached, although it's often the case that they are not used together and other advanced caching methods are instead implemented alongside Varnish.

Views Caching

Another type of database caching is Views caching. Views is a very popular, but rather resource intensive, Drupal module. Implementing Views caching can give your site a nice additional performance boost by possibly removing a few database queries from the build process.

To set views caching, go to your view. On the right hand side, under Advanced > Other, you'll see a link for Caching. Just go in and set a value - an hour is usually a good default - for each view on your site.

Wrapping Up Part One

Wow, long post and all we've really covered so far is backend performance and caching! This discussion hasn't been comprehensive by any means, but it does provide a great start.

Next time we'll start digging into frontend performance, the area where most of our performance issues reside. What should be obvious so far is that web performance is a subject that is both deep and wide, but also critically important to building successful websites.

If you have any comments about this post, you may politely leave them below.

LookAlive: Saving a serialized data Array as a property on a custom Entity (D7)

dim, 24/08/2014 - 21:42

Doing some initial prototyping work on the Comstack module I hit this question without a clear answer. For clarity here's a chunk of the schema structure for a Message Type (exportable entity).

/**
* Implements hook_schema().
*/
function comstack_schema() {
  $schema = array();

  $schema['comstack_message_type'] = array(
    'description' => 'Stores information about all defined {comstack_message} types.',
    'fields' => array(
      'id' => array(
        'type' => 'serial',
        'not null' => TRUE,
        'description' => 'Primary Key: Unique {comstack_message} type ID.',
      ),
    ...
    'delivery_methods' => array(
        'type' => 'text',
        'not null' => FALSE,
        'size' => 'big',
        'serialize' => TRUE,
        'description' => 'A serialized array of allowed send methods for this type.',
      ),

Following the instructions on how to create an exportable Entity as over here on d.o https://www.drupal.org/node/1021526 and here https://www.drupal.org/node/1021576

The second link has the following code which is the submit process where the form values are wrapped up and a new entity put together for you before saving.

/**
* Form API submit callback for the type form.
*/
function profile2_type_form_submit(&$form, &$form_state) {
  $profile_type = entity_ui_form_submit_build_entity($form, $form_state);
  ...

So how do we construct a form which will allow for arbitrary array structures? Like this (in your form function)!

  $form['delivery_methods'] = array(
    '#title' => t('Delivery methods to allow'),
    '#type' => 'checkboxes',
    '#required' => TRUE,
    '#options' => $delivery_methods,
    '#default_value' => isset($comstack_message_type->delivery_methods) ? $comstack_message_type->delivery_methods : array(),
    '#tree' => TRUE,
  );

It's the #tree bit there that does it. Here's an explanation from the Form API documentation page which is marked as archived but still useful https://www.drupal.org/node/48643.

When we set fieldset value to TRUE we create the form:

<?php
$form['colors'] = array(
'#type' => 'fieldset',
'#title' => t('Choose a color'),
'#collapsible' => FALSE,
'#tree' => TRUE,
);
$form['colors']['green'] = array(
'#type' => 'checkbox',
'#title' => t('Green'),
'#default_value' => $node->green,
'#required' => FALSE,
);

and this is how they are inserted or updated in a db_query:

<?php
function example_insert($node){
  db_query("INSERT INTO {example} (nid, question, green, blue) VALUES (%d,'%s', %d, %d)", $node->nid, $node->title, $node->colors['green'], $node->colors['blue']);
}

Any questions? Leave them in the comments :]

Doug Vann: 10 Useful Ways for Drupal Event Attendees To Be Engaged

sam, 23/08/2014 - 20:09

I am sitting here at DrupalCamp Asheville2014. I took a break and hung out in the BoF room and decided to compose this list of ideas on how Drupal Event attendees can engage the event.

I'd love to hear your comments below!

  1. Know The Session
    • What is this session about? Is it a show-n-tell of a module? Is it a case study of a website? If you are consciously aware of what to expect, then you are prepared to take what you hear and frame it within the context of the session topic. This is important for the attendee because not every element of the presentation will relate directly to the session topic. If the speaker needs to lay down some groundwork for a few minutes, it is important for you to remember what the overall topic is so that you don’t get lost in the weeds.
  2. Know The Session Speaker
    • Check out their Drupal.org Profile or their profile on the Event website. Get a sense of their background and perspective. This is also helpful if you ask questions at their session. You can ask questions that you know relate to elements of their background.
  3. Ask Questions At The Sessions
    • The number of questions at any given session will vary. But when there are none it can be a tad awkward. Then after the session, you might still see ppl walk up and ask questions.
    • I encourage you to fill in that silence with some immediate questions that come to mind. The speakers really really appreciate the questions.
  4. Engage Social Media
    • Tweet about the event. Maybe tweet about each session you attend and provide a link to the session description and invoke the speaker’s twitter name as well. 
    • Take pictures and post them wherever you post your pics.
    • Use the Hashtag if the event has one.
    • Do you blog? Blog about the event and what you liked.
    • The event organizers and spekers REALLY appreciate the media exposure.
    • Don’t forget that many Drupal events publish their videos online so you can catch the ones you missed or revisit the one you liked.
  5. Hang Out
    • Don’t feel like you have to attend a session in every timeslot. Feel free to hang out near the coffee tables or registration tables or in Birds of a Feather rooms. Wherever you see people hanging out, join them!
  6. Join A Stranger For Lunch
    • In general, the Drupal Community is a VERY social bunch. When it’s time to sit down and eat, it is also a good time to make some new friends. To the extent that you are comfortable with it, you can learn a lot by asking ppl how the event is going and what they do with Drupal.
  7. Get Swag
    • Walk around the sponsor’s booths and look for swag. These sponsors often DO NOT want to take that stuff back to the office. Sometimes you find some pretty useful things like shirts, pens, thumb drives, fold-up cloth flying disks, hackysacks, yo-yos, puzzles, keychains, etc.
  8. Talk To The Sponsors
    • I’ve never seen a sponsor bite or hard-sell a passerby at their booth! :-)
    • You may be amazed at what you will learn by reading the signs, looking at any literature on their table, and actually talking to the representative. 
  9. Fill Out Any Feedback Forms
    • Not ever event has feedback forms, but more and more are using them.
    • Forms may be available per-class, and for the event in general.
    • The organizers REALLY appreciate ALL comments.
    • As you might expect, the negative ones get more attention, so don’t hold back about the audio/video comments, or the need for more beginner topics, or how difficult it was to get to the venue from the airport, etc.
    • They really want to hear this!
  10. THANK The Organizers!
    • If you know their faces, be sure to thank them personally for their hard work organizing the speakers, the facilities, the meals, the WiFi, etc.
    • Be sure to tweet and post about it as well when you leave.

Daniel Pocock: Want to be selected for Google Summer of Code 2015?

sam, 23/08/2014 - 13:37

I've mentored a number of students in 2013 and 2014 for Debian and Ganglia and most of the companies I've worked with have run internships and graduate programs from time to time. GSoC 2014 has just finished and with all the excitement, many students are already asking what they can do to prepare and become selected in 2015.

My own observation is that the more time the organization has to get to know the student, the more confident they can be selecting that student. Furthermore, the more time that the student has spent getting to know the free software community, the more easily they can complete GSoC.

Here I present a list of things that students can do to maximize their chance of selection and career opportunities at the same time. These tips are useful for people applying for GSoC itself and related programs such as GNOME's Outreach Program for Women or graduate placements in companies.

Disclaimers

There is no guarantee that Google will run the program again in 2015 or any future year.

There is no guarantee that any organization or mentor (including myself) will be involved until the official list of organizations is published by Google.

Do not follow the advice of web sites that invite you to send pizza or anything else of value to prospective mentors.

Following the steps in this page doesn't guarantee selection. That said, people who do follow these steps are much more likely to be considered and interviewed than somebody who hasn't done any of the things in this list.

Understand what free software really is

You may hear terms like free software and open source software used interchangeably.

They don't mean exactly the same thing and many people use the term free software for the wrong things. Not all open source projects meet the definition of free software. Those that don't, usually as a result of deficiencies in their licenses, are fundamentally incompatible with the majority of software that does use approved licenses.

Google Summer of Code is about both writing and publishing your code and it is also about community. It is fundamental that you know the basics of licensing and how to choose a free license that empowers the community to collaborate on your code.

Please read up on this topic early on and come back and review this from time to time. The The GNU Project / Free Software Foundation have excellent resources to help you understand what a free software license is and how it works to maximize community collaboration.

Don't look for shortcuts

There is no shortcut to GSoC selection and there is no shortcut to GSoC completion.

The student stipend (USD $5,500 in 2014) is not paid to students unless they complete a minimum amount of valid code. This means that even if a student did find some shortcut to selection, it is unlikely they would be paid without completing meaningful work.

If you are the right candidate for GSoC, you will not need a shortcut anyway. Are you the sort of person who can't leave a coding problem until you really feel it is fixed, even if you keep going all night? Have you ever woken up in the night with a dream about writing code still in your head? Do you become irritated by tedious or repetitive tasks and often think of ways to write code to eliminate such tasks? Does your family get cross with you because you take your laptop to Christmas dinner or some other significant occasion and start coding? If some of these statements summarize the way you think or feel you are probably a natural fit for GSoC.

An opportunity money can't buy

The GSoC stipend will not make you rich. It is intended to make sure you have enough money to survive through the summer and focus on your project. Professional developers make this much money in a week in leading business centers like New York, London and Singapore. When you get to that stage in 3-5 years, you will not even remember exactly how much you made during internships.

GSoC gives you an edge over other internships because it involves publicly promoting your work. Many companies still try to hide the potential of their best recruits for fear they will be poached or that they will be able to demand higher salaries. Everything you complete in GSoC is intended to be published and you get full credit for it. Imagine an amateur musician getting the opportunity to perform on the main stage at a rock festival. This is how the free software community works.

Having a portfolio of free software that you have created or collaborated on and a wide network of professional contacts that you develop before, during and after GSoC will continue to pay you back for years. While other graduates are being screened through group interviews and testing days run by employers, people with a track record in a free software project often find they go straight to the final interview round.

Register your domain name and make a permanent email address

Free software is all about community and collaboration. Register your own domain name as this will become a focal point for your work and for people to get to know you as you become part of the community.

This is sound advice for anybody working in IT, not just programmers. It gives the impression that you are confident and have a long term interest in a technology career.

Choosing the provider: as a minimum, you want a provider that offers DNS management, static web site hosting, email forwarding and XMPP services all linked to your domain. You do not need to choose the provider that is linked to your internet connection at home and that is often not the best choice anyway. The XMPP foundation maintains a list of providers known to support XMPP.

Create an email address within your domain name. The most basic domain hosting providers will let you forward the email address to a webmail or university email account of your choice. Configure your webmail to send replies using your personalized email address in the From header.

Update your ~/.gitconfig file to use your personalized email address in your Git commits.

Create a web site and blog

Start writing a blog. Host it using your domain name.

Some people blog every day, other people just blog once every two or three months.

Create links from your web site to your other profiles, such as a Github profile page. This helps re-inforce the pages/profiles that are genuinely related to you and avoid confusion with the pages of other developers.

Many mentors are keen to see their students writing a weekly report on a blog during GSoC so starting a blog now gives you a head start. Mentors look at blogs during the selection process to try and gain insight into which topics a student is most suitable for.

Create a profile on Github

Github is one of the most widely used software development web sites. Github makes it quick and easy for you to publish your work and collaborate on the work of other people. Create an account today and get in the habbit of forking other projects, improving them, committing your changes and pushing the work back into your Github account.

Github will quickly build a profile of your commits and this allows mentors to see and understand your interests and your strengths.

In your Github profile, add a link to your web site/blog and make sure the email address you are using for Git commits (in the ~/.gitconfig file) is based on your personal domain.

Start using PGP

Pretty Good Privacy (PGP) is the industry standard in protecting your identity online. All serious free software projects use PGP to sign tags in Git, to sign official emails and to sign official release files.

The most common way to start using PGP is with the GnuPG (GNU Privacy Guard) utility. It is installed by the package manager on most Linux systems.

When you create your own PGP key, use the email address involving your domain name. This is the most permanent and stable solution.

Print your key fingerprint using the gpg-key2ps command, it is in the signing-party package on most Linux systems. Keep copies of the fingerprint slips with you.

This is what my own PGP fingerprint slip looks like. You can also print the key fingerprint on a business card for a more professional look.

Using PGP, it is recommend that you sign any important messages you send but you do not have to encrypt the messages you send, especially if some of the people you send messages to (like family and friends) do not yet have the PGP software to decrypt them.

If using the Thunderbird (Icedove) email client from Mozilla, you can easily send signed messages and validate the messages you receive using the Enigmail plugin.

Get your PGP key signed

Once you have a PGP key, you will need to find other developers to sign it. For people I mentor personally in GSoC, I'm keen to see that you try and find another Debian Developer in your area to sign your key as early as possible.

Free software events

Try and find all the free software events in your area in the months between now and the end of the next Google Summer of Code season. Aim to attend at least two of them before GSoC.

Look closely at the schedules and find out about the individual speakers, the companies and the free software projects that are participating. For events that span more than one day, find out about the dinners, pub nights and other social parts of the event.

Try and identify people who will attend the event who have been GSoC mentors or who intend to be. Contact them before the event, if you are keen to work on something in their domain they may be able to make time to discuss it with you in person.

Take your PGP fingerprint slips. Even if you don't participate in a formal key-signing party at the event, you will still find some developers to sign your PGP key individually. You must take a photo ID document (such as your passport) for the other developer to check the name on your fingerprint but you do not give them a copy of the ID document.

Events come in all shapes and sizes. FOSDEM is an example of one of the bigger events in Europe, linux.conf.au is a similarly large event in Australia. There are many, many more local events such as the Debian France mini-DebConf in Lyon, 2015. Many events are either free or free for students but please check carefully if there is a requirement to register before attending.

On your blog, discuss which events you are attending and which sessions interest you. Write a blog during or after the event too, including photos.

Quantcast generously hosted the Ganglia community meeting in San Francisco, October 2013. We had a wild time in their offices with mini-scooters, burgers, beers and the Ganglia book. That's me on the pink mini-scooter and Bernard Li, one of the other Ganglia GSoC 2014 admins is on the right.

Install Linux

GSoC is fundamentally about free software. Linux is to free software what a tree is to the forest. Using Linux every day on your personal computer dramatically increases your ability to interact with the free software community and increases the number of potential GSoC projects that you can participate in.

This is not to say that people using Mac OS or Windows are unwelcome. I have worked with some great developers who were not Linux users. Linux gives you an edge though and the best time to gain that edge is now, while you are a student and well before you apply for GSoC.

If you must run Windows for some applications used in your course, it will run just fine in a virtual machine using Virtual Box, a free software solution for desktop virtualization. Use Linux as the primary operating system.

Here are links to download ISO DVD (and CD) images for some of the main Linux distributions:

If you are nervous about getting started with Linux, install it on a spare PC or in a virtual machine before you install it on your main PC or laptop. Linux is much less demanding on the hardware than Windows so you can easily run it on a machine that is 5-10 years old. Having just 4GB of RAM and 20GB of hard disk is usually more than enough for a basic graphical desktop environment although having better hardware makes it faster.

Your experiences installing and running Linux, especially if it requires some special effort to make it work with some of your hardware, make interesting topics for your blog.

Decide which technologies you know best

Personally, I have mentored students working with C, C++, Java, Python and JavaScript/HTML5.

In a GSoC program, you will typically do most of your work in just one of these languages.

From the outset, decide which language you will focus on and do everything you can to improve your competence with that language. For example, if you have already used Java in most of your course, plan on using Java in GSoC and make sure you read Effective Java (2nd Edition) by Joshua Bloch.

Decide which themes appeal to you

Find a topic that has long-term appeal for you. Maybe the topic relates to your course or maybe you already know what type of company you would like to work in.

Here is a list of some topics and some of the relevant software projects:

  • System administration, servers and networking: consider projects involving monitoring, automation, packaging. Ganglia is a great community to get involved with and you will encounter the Ganglia software in many large companies and academic/research networks. Contributing to a Linux distribution like Debian or Fedora packaging is another great way to get into system administration.
  • Desktop and user interface: consider projects involving window managers and desktop tools or adding to the user interface of just about any other software.
  • Big data and data science: this can apply to just about any other theme. For example, data science techniques are frequently used now to improve system administration.
  • Business and accounting: consider accounting, CRM and ERP software.
  • Finance and trading: consider projects like R, market data software like OpenMAMA and connectivity software (Apache Camel)
  • Real-time communication (RTC), VoIP, webcam and chat: look at the JSCommunicator or the Jitsi project
  • Web (JavaScript, HTML5): look at the JSCommunicator

Before the GSoC application process begins, you should aim to learn as much as possible about the theme you prefer and also gain practical experience using the software relating to that theme. For example, if you are attracted to the business and accounting theme, install the PostBooks suite and get to know it. Maybe you know somebody who runs a small business: help them to upgrade to PostBooks and use it to prepare some reports.

Make something

Make some small project, less than two week's work, to demonstrate your skills. It is important to make something that somebody will use for a practical purpose, this will help you gain experience communicating with other users through Github.

For an example, see the servlet Juliana Louback created for fixing phone numbers in December 2013. It has since been used as part of the Lumicall web site and Juliana was selected for a GSoC 2014 project with Debian.

There is no better way to demonstrate to a prospective mentor that you are ready for GSoC than by completing and publishing some small project like this yourself. If you don't have any immediate project ideas, many developers will also be able to give you tips on small projects like this that you can attempt, just come and ask us on one of the mailing lists.

Ideally, the project will be something that you would use anyway even if you do not end up participating in GSoC. Such projects are the most motivating and rewarding and usually end up becoming an example of your best work. To continue the example of somebody with a preference for business and accounting software, a small project you might create is a plugin or extension for PostBooks.

Getting to know prospective mentors

Many web sites provide useful information about the developers who contribute to free software projects. Some of these developers may be willing to be a GSoC mentor.

For example, look through some of the following:

Getting on the mentor's shortlist

Once you have identified projects that are interesting to you and developers who work on those projects, it is important to get yourself on the developer's shortlist.

Basically, the shortlist is a list of all students who the developer believes can complete the project. If I feel that a student is unlikely to complete a project or if I don't have enough information to judge a student's probability of success, that student will not be on my shortlist.

If I don't have any student on my shortlist, then a project will not go ahead at all. If there are multiple students on the shortlist, then I will be looking more closely at each of them to try and work out who is the best match.

One way to get a developer's attention is to look at bug reports they have created. Github makes it easy to see complaints or bug reports they have made about their own projects or other projects they depend on. Another way to do this is to search through their code for strings like FIXME and TODO. Projects with standalone bug trackers like the Debian bug tracker also provide an easy way to search for bug reports that a specific person has created or commented on.

Once you find some relevant bug reports, email the developer. Ask if anybody else is working on those issues. Try and start with an issue that is particularly easy and where the solution is interesting for you. This will help you learn to compile and test the program before you try to fix any more complicated bugs. It may even be something you can work on as part of your academic program.

Find successful projects from the previous year

Contact organizations and ask them which GSoC projects were most successful. In many organizations, you can find the past students' project plans and their final reports published on the web. Read through the plans submitted by the students who were chosen. Then read through the final reports by the same students and see how they compare to the original plans.

Start building your project proposal now

Don't wait for the application period to begin. Start writing a project proposal now.

When writing a proposal, it is important to include several things:

  • Think big: what is the goal at the end of the project? Does your work help the greater good in some way, such as increasing the market share of Linux on the desktop?
  • Details: what are specific challenges? What tools will you use?
  • Time management: what will you do each week? Are there weeks where you will not work on GSoC due to vacation or other events? These things are permitted but they must be in your plan if you know them in advance. If an accident or death in the family cut a week out of your GSoC project, which work would you skip and would your project still be useful without that? Having two weeks of flexible time in your plan makes it more resilient against interruptions.
  • Communication: are you on mailing lists, IRC and XMPP chat? Will you make a weekly report on your blog?
  • Users: who will benefit from your work?
  • Testing: who will test and validate your work throughout the project? Ideally, this should involve more than just the mentor.

If your project plan is good enough, could you put it on Kickstarter or another crowdfunding site? This is a good test of whether or not a project is going to be supported by a GSoC mentor.

Learn about packaging and distributing software

Packaging is a vital part of the free software lifecycle. It is very easy to upload a project to Github but it takes more effort to have it become an official package in systems like Debian, Fedora and Ubuntu.

Packaging and the communities around Linux distributions help you reach out to users of your software and get valuable feedback and new contributors. This boosts the impact of your work.

To start with, you may want to help the maintainer of an existing package. Debian packaging teams are existing communities that work in a team and welcome new contributors. The Debian Mentors initiative is another great starting place. In the Fedora world, the place to start may be in one of the Special Interest Groups (SIGs).

Think from the mentor's perspective

After the application deadline, mentors have just 2 or 3 weeks to choose the students. This is actually not a lot of time to be certain if a particular student is capable of completing a project. If the student has a published history of free software activity, the mentor feels a lot more confident about choosing the student.

Some mentors have more than one good student while other mentors receive no applications from capable students. In this situation, it is very common for mentors to send each other details of students who may be suitable. Once again, if a student has a good Github profile and a blog, it is much easier for mentors to try and match that student with another project.

Conclusion

Getting into the world of software engineering is much like joining any other profession or even joining a new hobby or sporting activity. If you run, you probably have various types of shoe and a running watch and you may even spend a couple of nights at the track each week. If you enjoy playing a musical instrument, you probably have a collection of sheet music, accessories for your instrument and you may even aspire to build a recording studio in your garage (or you probably know somebody else who already did that).

The things listed on this page will not just help you walk the walk and talk the talk of a software developer, they will put you on a track to being one of the leaders. If you look over the profiles of other software developers on the Internet, you will find they are doing most of the things on this page already. Even if you are not selected for GSoC at all or decide not to apply, working through the steps on this page will help you clarify your own ideas about your career and help you make new friends in the software engineering community.

Mediacurrent: My first Design 4 Drupal conference

ven, 22/08/2014 - 22:16

Ever since the Drupal community started holding national regional conferences, dubbed DrupalCons and DrupalCamps, there has been a perception that design, usability and “theming” (i.e., managing HTML, CSS and JS output) were afterthoughts. And, to be honest, that has been true for many camps and conferences – while developers were geeking out on advanced Views API usage and performance tuning, those looking for a design focus were often left with introductory theming sessions.
