As you may know, this year's Dutch PHP Conference will again take place in Amsterdam in a well-known convention centre called "RAI". At the end of the Tutorial Day we will head back to the centre of town for the second edition of the Code Night...
Last time I blogged about DPC, we were still waiting for some speakers to confirm their presence. Now I can tell you that the schedule is complete (with some of the more recent additions: Sara Goleman with talks on HHVM extensions and types, and Christopher Pitt on functional programming and automation). Don't forget to buy your tickets - Early Bird prices are available until April 22nd!
Now it's time to shine a bit more light on the tutorial day, right before the main conference days (on June 23rd). We have made quite a broad selection of topics:
Hey, guess what, as someone in charge of corporate security for a web development shop, I am not cool with this. I am like totally not cool with this.
I'm not talking about you sharing your personal Netflix account with friends and family (that may not be as security savy as you are). I'm talking about building systems that tightly couple user and resource or charge for additional accounts, thereby encouraging the user to share his or her credentials!
A couple of weeks ago we announced the schedule for the Dutch PHP Conference. I already mentioned that we have a great selection of experienced speakers as well as many speakers who are less familiar with the conference stage but are eager (and ready) to take it. At the main conference days we have 5 tracks packed with interesting talks. At the beginning of the first day and at the end of the second day we'll have a keynote. Let me briefly introduce the keynote speakers to you now!
It's been a great honor to receive a total of 350 talk and tutorial proposals for the 10th edition of our annual Dutch PHP Conference. Proposals covered a wide range of topics. Many talk proposals had been submitted by experienced speakers, some by absolute beginners. A number of speakers seems to have proven their skills at local meetups and are now ready to take the stage on a conference like DPC, where there might be a 100 or up to 220 people listening to you.
This is the first blog post in what will hopefully become a new series where we look at old Drupal 7 & 8 security advisories (at least 3 months ago so they should be patched everywhere) and try to learn from the mistakes of others.
As a first post I'd like to pick an older vulnerability, one I've used in presentations to demonstrate how hard it can be to properly apply HTML encoding for Drupal.
In the previous parts of this series we looked at how to get rid of complexity at the level of algorithms. After discussing the problem of nulls in your code, we looked at object lifecycles and how to encapsulate them properly. Now that we have objects that can be constructed and changed only in valid ways, we need to look at how they communicate with each other and how we can improve our code with regard to that aspect.
This year Ibuildings will host the Dutch PHP Conference (DPC) in Amsterdam for the tenth time in a row, on June 23rd - 25th. As you may have noticed, since a couple of weeks you can send in your tutorial or talk proposals. The Call for Papers closes on February 22nd.
In the first part of this series we looked at ways to reduce the complexity of function bodies. The second part covered several strategies for reducing complexity even more, by getting rid of null in our code. In this article we'll zoom out a bit and look at how to properly organize the lifecycle of our objects, from creating them to changing them, letting them pass away and bringing them back from the dead.
In the previous part of this series we looked at what are basically a lot of guidelines for achieving "clean code". In this part I'd like to take a closer look at something we call null. Our main goal will be: to get rid of it.
PHP is pretty much a freestyle programming language. It's dynamic and quite forgiving towards the programmer. As a PHP developer you therefore need a lot of discipline to get your code right. Over the years I've read many programming books and discussed code style with many fellow developers. I can't remember which rules come from which book or person, but this article (and the following ones) reflect what I see as some of the most helpful rules for delivering better code: code that is future-proof, because it can be read and understood quite well. Fellow developers can reason about it with certainty, quickly spot problems, and easily use it in other parts of a code base.
I can still remember seeing jQuery for the first time. Then we got Node JS! Running client-side code on Node wasn’t always possible, and ECMAScript 6 was great in theory, but how long would we have to wait until all browsers were updated? Much to my surprise, these problems are gone!
With many, many open issues (15496 at the time of writing) for Drupal core alone and even more issues for all the contributed modules it can feel like a big hurdle to start contributing to the project.
Last year we switched to using Slack for all our internal communication and it's working out nicely. It's very developer centric in that it offers integrations with lots of services like Travis CI, GitHub, etc.
When we started using Slack one of our developers was sending a file, had his Developer console open and noticed that even though he'd not chosen to share the file public, the API gave back a public URL anyway. Much to his dismay when he tried it out in a new private browsing window he could download his file without authentication!
Everything you share on Slack automatically becomes available on a public url.
Concerned with the security of our communications (we don't share financials or credentials through Slack fortunately, but we may share company or customer sensitive information) I decided to look into it and make it a teachable moment on 'secret URLs'.
