stripeIf there’s one thing experience has taught us here at Digital Peak, it’s that accepting online payments on a global scale is incredibly complex. For bodies that don’t need international payment support, it’s easy enough – just have a local bank account and give people direct debit details. In theory, you could do the same for overseas orders – but telegraphic transfers take time and, more importantly, can be very expensive for the buyer. Large organisations with physical presences in multiple countries can, of course, simply create bank accounts in all the countries they operate – but that obviously doesn't apply to Digital Peak. And as for cheques or money orders, that’s entirely out of the picture.

By far and away the best option is still to accept credit card payments. But credit card merchant accounts can be expensive and have criteria you don’t qualify for – and if you needed to accept multiple credit cards, you may need multiple merchant accounts. The better solution would be to work with an organisation that could itself process credit cards, and paid you in cash to your current bank account. These organisations are PCI DSS compliant to fulfill the highest security standards to safely handle your transactions.

Enter PayPal

Which, if you have been our subscriber for a while, you will notice we have been doing all this time through PayPal. Now, PayPal when we first started out using it was great. Its fees were reasonably low, it had a number of features we liked, we got our money in a timely fashion and most importantly, our subscribers didn't necessarily need to have a PayPal account to use it. In this respect, it worked just like a regular online credit card payment gateway or processor. We needed an account, but it was no real hardship. There’s a reason why PayPal has more or less monopolized the online payment market.

Today, though, PayPal is no longer so great. You can see it start to flex its muscles in various ways, mostly in ways that don’t directly affect us – its anti-porn stance, for instance. However, there is one way in which it has changed which does affect us. That is, it seems to now require you to register an account before you can use it. Apparently, not all countries and regions are affected – but that very uncertainty makes it a non-optimal choice.

Move Over, Stripe’s Coming Through

Enter Stripe, our new alternate payment gateway. It is a platform which handles all the credit card processing for the merchant, but does not currently require setting up an account on the part of the buyers. It has a host of other features that makes it amazingly attractive. It has a well-rounded API which works on just about every platform that is out there. You can now enter your credit card information directly on our web site and it will be transferred over a secure (https) connection to the stripe platform. We do not store your credit card information on our servers at all.

So if you’re one of those people who’s fed up with PayPal and its aggressive posture, then go ahead and pay for your subscription using Stripe. It’s not any harder to use. And if you’re happy with PayPal, then go ahead – we won’t be shutting it down any time soon. At least now, you have a choice.

translate-transifexMore so than any other language, English can lay claim to being truly international. More people speak Mandarin, but most of them are ethnic Chinese concentrated in mainland China and Taiwan. The created language Esperanto is supposed to be international, but it is spoken only by a few million, as opposed to more than a billion English speakers. It is an official language in approximately 1/3 of the world’s nations, as well as that of the European Union. It is the only language used by international air traffic control (a regulation by ICAO). And English words form the basis for most of the more common and popular programming languages. We at Digital Peak are not Englishmen, but we speak, read and write in English (albeit not perfectly all the time).

This being the case, it is not surprising that the early Internet and World Wide Web started out as being predominantly English-based as well. As English is also the international language of the sciences and other academic studies, and as the Internet started becoming popular amongst universities, one can see why this is the case. Today, much of the Internet and the Web remains heavily biased towards English. For instance, Digital Peak’s CMS of choice, Joomla!, supports multiple languages, but the official website is solely in English.

However, that is changing, and has been changing over the past decade. An internationalized software package has access to a greater marketplace, and provides its users with more seamless experiences and wider options. Many factors have come together to drive the internationalization and localisation of software in all the various human languages; the seamless support for Unicode amongst the primary OS players and font developers, the rapid improvement of machine translation, and most of all, crowdsourcing. Joomla itself relies heavily on crowdsourcing for its non-English language support.

Traditionally, translating anything, much less something as complex as software, has been a difficult, expensive and time-consuming process. In addition to the high costs and cultural, sometimes political ramifications that may impact normal translation, software poses its own unique problems as well, since many US-centric third-party developers often assume English language strings and operate on such assumptions. Raymond Chen has highlighted some delightful anecdotes about how the Windows team comes across such issues in his book, The Old New Thing (also the name of his blog).

Today, though, through the power of crowdsourcing, translation of software into different languages no longer has to be expensive or time-consuming (although it may still be a bit challenging). We at Digital Peak use a cloud solution called Transifex. Free for open source projects (they also have paid plans for seriously large projects), Transifex offers an impressive array of features and facilities in order to ensure that translations of all the language strings in our projects are timely, and as we update our Joomla extensions, we can have all the documentation associated with them translated in near real-time.

You, too, can be a part of the Digital Peak translation team on Transifex! Just sign up and apply to be a contributor. We can be found here on Transifex, so come on by and help out. You’ll have the satisfaction of knowing that you helped to make our great extensions even more awesome. The full documentation how to help translate can be found here. We always update the translation files before we ship a new release. Means, you contribution will be shipped very quickly.



I'm sitting in my living room and think about how should I write an article that the loved GCalendar extensions has evolved and will be now DPCalendar Free? Should I write what has changed or why did we do that or where do we want go? I guess I start with some background information about GCalendar and DPCalendar.

GCalendar vs DPCalendar

I published GCalendar in the JED in 2007, over seven years ago, as a free (in beer and in use) extension. It was the only full featured Google calendar extension for Joomla at that time and continues to be the best Google calendar extension. The first version of GCalendar was created for Joomla v1.0.x series. Over the years many people have contributed to GCalendar. And the forum has grown with almost 25'000 posts. GCalendar has been downloaded over 2 million times at

The demand of the community increased and there were requests for many features that Google's calendar could not support. This meant we should keep the same slick interface but we needed to add the events to the Joomla database, instead of Google's.

We decided to make a commercial calendar version to deliver a professional Joomla calendar and event manager extension. DPCalendar was born! DPCalendar has grown very fast and supports now CalDAV access to its calendars, payment gateways to attend events and tons of external calendar integration plugins like CalDAV/iCloud/ownCloud, Google calendar, Facebook pages, MS Exchange or iCal events (Yahoo,, and many other calendars). To name just a few features.

During this time, GCalendar was at a very stable state and not many changes were needed. We published the GCalendar Action Pack to edit the Google events directly from within Joomla. Minor tweaks and updates have slowed. The options to grow and add new features for GCalendar are very limited due to the Google calendar limitations.

Having one product

Maintaining three products, GCalendar, Action Pack, and DPCalendar, which do basically the same thing was inefficient. Paul and I were discussing back and forth what should we do. I wanted to reduce the development time to be able to put energy into only one calendar extension. At the same time to provide a healthy free event extension for the masses and a commercial one for professionals with proper support. We decided there must be only one product and it will be DPCalendar. But how should the free version look like?

Making a free version

First we thought that we should slim down DPCalendar and provide it with the Google calendar plugin. But that would be more confusing to the people. They would basically have an empty component and a very powerful Google calendar plugin. A next idea was to make DPCalendar free without the external plugins. But what would be the migration path for the GCalendar users? We didn't want to force them to buy the DPCalendar professional version just to be able to use their existing Google calendars. So we decided at the end to make a slimmed down version of DPCalendar with a GCalendar integration plugin. This means that the free version of DPCalendar has a reduced feature set (no CalDAV support, no attending feature, etc.) and the existing GCalendar users can integrate or import their GCalendars. New DPCalendar Free users will have then events stored into the database and benefit from the much richer feature set than GCalendar had.

The table below shows the different versions and feature sets:

Feature Free Standard
Professional Premium
Component (The free version does not contain features like CalDAV access, recurring events or the list/map view and some more.)        
Upcoming Module        
Counter Module        
Mini Module        
Map Module        
Search Plugin
Finder Plugin
Ical Plugin        
Jomsocial Plugin        
CSV Plugin        
JEvents Plugin        
JCalPro Plugin        
Google Calendar Plugin        
Facebook Event Plugin        
CalDAV Plugin        
MS Exchange Plugin        
Manual Payment Plugin        
PayPal Payment Plugin        

What can the DPCalendar Google plugin do?

The DPCalendar Google plugin uses the newest Google Calendar API v3 with OAuth2 authentication (it is not required anymore to store your google credentials in DPCalendar). This API is much faster because it uses JSON as transport protocol. More features which are available only in this API v3 are event colors. Events can created/updated/deleted directly from your Joomla web site.

The API v3 doesn't rely on Zend anymore which makes the footprint much smaller and the Zend_Loader errors are history.

What happens to my Action Pack subscription?

We migrate all GCalendar Action Pack subscriptions in the next couple of days from to The subscription will be turned into a DPCalendar professional subscription with the length the Action Pack had. All subscriptions which are expired or less than two months valid will be activated and end two months after migration that you will have enough time to do the move. We will not leave you out in the rain.

Why do I have to do the move?

Google is shutting down their API version 1 which is used in GCalendar on 17. November 2014. You can read the announcement here. GCalendar will not work anymore after that, but the DPCalendar - GCalendar plugin will. You will find all information here how to do the migration from GCalendar to DPCalendar (Free).

Where are we going?

We always want to provide a free extension for the Joomla community because we get back so much from the community. This means there will be always a FREE DPCalendar version. To the subscribers we offer top notch support, a cutting edge DPCalendar version and tons of plugins like Facebook integration or PayPal payments. I really hope that you are taking the next steps with us and that the new strategy will be a success story for all of us, the team of Digital Peak and the Joomla community.

dpcalendar-4 0

We've been working hard in the last couple of weeks to deliver the most feature rich DPCalendar version to our friends and community. The DPCalendar 4.0 release is a new milestone in the area of Digital Peak as we provide now an all in one event experience. The users can navigate through your events on the ajax based intuitive interface or based on locations. Let them attend the events and if needed let them pay for it through our new payment plugins "Manual payment" or "PayPal payment" (more payment plugins will come soon). Send out notifications to get them back to your site. Or do you need to import unlimited Google calendars. We have it now! Read on for a more detailed list of killer features in this release.

Payment Plugins

dpcalendar-4 0-options

A long demandig feature request was to support some payment processors for attendancees to extend DPCalendar to a reservation system. You can now define in the attending options of DPCalendar a price the attendee has to pay for and a payment type with which she/he has to do the payment. On the attending form the visitor can to choose then from one of this options to make the payment.

It sounds like a simple addon but in the background we had to make big changes as it was needed to completely revamp the old workflow. We are proud now to deliver such a feature to you. In the future we will implement more payment gateways like 2checkout, or more. We will see what er the biggest needs from our customers.

Unlimited external calendars

Since the beginning, DPCalendar was designed to support external calendar sources like Facebook pages, CalDAV servers, MS Exchange, Google calendar or more in a seamless way that the visitor will get insights into ALL your events on your Joomla site in one place. We had a limit of 10 calendars per external calendar plugin which was enough for most of our customers but not all. Because of that we implemented in the plugin options a completely new external calendar system which enables the site admin to add as many external calendars as needed.

For the most popular plugins like Google calendar, Facebook pages or CalDAV servers (iCloud, ownCloud, etc.) we made some importers for a hassle free quick setup.

More little features

We packed the verison 4 with tons of new nice little features. We have now an Xmap plugin to add your events easily to your sitemap. A new finder plugin integrates the DPCalendar events into smart search and events from Google can be edited directly in DPCalendar. The changes will be written back to Google immediately. To prevent spam events you can force certain user groups to add a captcha code when editing an event in the front.

What has changed?

Some legacy features like jQuery UI themes are removed in this version and we come now with single installer files for every kind of subscription. If you add the download ID we even support the Joomla core updates. Means you don't have to go extra to the DPCalendar control panel and do the update manually. You will get notified through the Joomla updated manager where the updates can be don through it.

The best comes last

Since I put my shoes into the IT world I'm an advocate of Open Source, that's the reason why I started to use Joomla. In my first years of Joomla extension development I gave away my extensions for free with the same passion or even more as I would get payed for it. So became GCalendar one of the most popular Joomla extension. The demand of the community increased and I decided to make a commercial version of GCalendar. DPCalendar was born! DPCalendar grow and became mature with a much more advanced feature set than it was ever possible with GCalendar. At the same time I wanted to give the Joomla community something back, that's the reason why we are offering a FREE version of DPCalendar which as basically the next step in the evolution of GCalendar. If you are a GCalendar user please read the migration guide how to do the transition from GCalendar to DPCalendar.


Allon Moritz (aka laoneo) founder of Digital Peak


By now security and Web experts all over the world have gone berserk over a new – and exceedingly terrifying – vulnerability in the latest versions of OpenSSL called Heartbleed. Since the Joomla! CMS is in use by some of the world’s largest companies for their websites, and since OpenSSL is in use by many, many LAMP architectures (not only by Linux, but also by Apache), and since LAMP is the platform Joomla mostly runs on, we thought we’d give you a quick rundown on what the Heartbleed vulnerability means, whether you are affected by it, and what you can do to fix it.

Firstly, though, let’s give the good news first. If you are in total control over your Joomla website (especially the LAMP part), then you can easily fix Heartbleed on your website (and we’ll tell you how later on). If you are using WIMP or some other SSL implementation library (such as Microsoft’s SChannel or GnuTLS), then rejoice! for the Heartbleed vulnerability does not affect your website in the least. If you are using an older version of OpenSSL (i.e. 1.0.0 or lower), there is no corresponding vulnerability. And of course, if your website does not use SSL/TLS, then this is not an issue for it either.

Now, the bad news. OpenSSL is one of the most popular Free and Open Source (FOSS) SSL/TLS implementation libraries on the world, and Heartbleed affects all OpenSSL 1.0.1 releases until 1.0.1g (which was when it was patched and released on 7th April 2014). Since 1.0.1 came out in 2012, this means that this vulnerability has been around for about 2 years. So, even if your Joomla-powered website is not affected, you probably are. A worst-case scenario shows that about 66% (or 2/3) of the Web could be affected; a more realistic estimate is about 17%-18%, which is still significant (especially if it’s the right – or in this case wrong – 17%-18%).

So what is the Heartbleed (CVE-2014-0160) bug? In essence, it is an implementation bug (not inherent in the actual protocol) involving TLS (more specifically, the TLS heartbeat extension as specified in RFC6520). Some developer of OpenSSL back in 2012 missed a bounds check, which led to an attacker being able to read up to 64kb of process memory on either the implementing server, or a connected client (albeit to an ‘evil’ server).

The problem is that 64KB of RAM is the limit for a single Heartbleed attack. Attackers can spawn any number of attacks, thus reading any arbitrary amount of RAM they want to read that has been allocated to the process. And on a webserver, that includes the most critical component of SSL, the server’s secret/private key used to generate the SSL certificates. That key has to be in RAM, because that’s what is used to decrypt the SSL/TLS-encrypted data. While it can also uncover other bits of data (e.g. usernames, passwords, financial information), that’s not as critical as the fact that it can effortlessly conduct man-in-the-middle attacks and even impersonate the webserver. Imagine the ramifications for major banks and cloud storage providers, for instance.

So, if your website is affected, what can you do about it? For your Joomla-powered website, check and make sure that all of the OpenSSL libraries you’re using (OS and Web server, but possibly also your Joomla extensions) have been updated to the latest version (1.0.1g) or have been patched (many Linux distributions are patching 1.0.1f, and others are backporting the patch all the way back to 1.0.1). After patching or installing the latest version, restart your server (probably best to do a cold boot if you can). If your website is a hosted one, your options are more limited; you will have to bug your webhost to upgrade their systems – but most responsible webhosts should be doing so within the week anyway.

You then need to revoke your existing certificates and create new private keys and fresh certificates (see if your certificate vendor will give you a discount or even make it free). Use a checker like or to verify that your server’s security is no longer compromised. And most importantly, tell your users that you have already fixed the Heartbleed problem, so they should reset their passwords immediately.

This is quite possibly the worst-case scenario for Internet security since the inception of Internet security. It definitely blows the Snowden disclosures out of the water in terms of its impact – it’s a truly global issue and affects everybody.
