30 years later

I bought my first Game Boy less than 30 years ago. It must have been in the summer of 1991 when I was in England for a language course during the summer holidays. I scraped together all my pocket money and bought with excitement the console and two games: Dynablaster and Super Mario Land.

The first one was the European version of Bomberman, which you could even play against each other, assuming two modules and the multiplayer adapter, of course. And I think that I don't really have to explain Super Mario Land. The name speaks for itself.

But I never managed to play through the entire twelve levels. No idea why. Until last night. With the last life. One less game on the pile of shame.

Surf another way

Update: With release of TYPO3 10.4.8 the problem is gone because the dependencies were adjusted. Apparently there were problems not only with Surf, but also with Solr and dependencies on PHP 7.2. Nevertheless, I will not install Surf with composer in the project, but instead globally in the DDEV container.

Yesterday a planned maintenance update of TYPO3 was published. Version 10.4.7. The best content management system that I know. And of course all projects should get the new version. What was previously possible without any problems with a hearty 'composer update' without any other effort. Just not yesterday.

composer absolutely refused to integrate the new version into the projects. Okay, no problem, let us approach the whole thing systematically. First with 

composer clear-cache && composer update

force composer to forget everything, go through all the sources and try again. But this did not bring any new TYPO3 onto the hard drive.

Then I would look around and with the question

composer why-not typo3/cms-core:10.4.7

it became clear that typo3/surf has a dependency with symfony/console which finally has a dependency with symfony/event-dispatcher-contracts that prevented going to a larger version than 2.0. But what typo3/cms-core absolutely requires. npm, what the hell!

This morning I tried another time to find a solution but maybe I should think about another job in my elderly age. So there was only Twitter left, my grief complained and minutes later the two heroes @t3easy_de and @chriwode came around the corner.

The first attempt to run Surf locally on Windows failed miserably. Yes, Windows. I don't want to talk about that here. The whole thing fails because, among other things, Windows does not know awk and even if you install this, you will be hit with further errors.

To get to the point: so far I have setup projects using DDEV and not only installed TYPO3 and the extensions used via composer, but also Surf. In order to be able to deploy a project via the command line, for example, if no corresponding CI/CD system is available. My solution now looks like this: Surf has removed of this composer.json and is installed globally via the DDEV start hook:

  - exec: composer global require hirak/prestissimo
  - exec: composer global require typo3/surf:^2.0

So TYPO3 10.4.7 can be installed and I can move the project to another system via surf.

Speed is everything

There are investigations for everything. Also for how the loading time of a website affects the possible bounce rate of the visitors. And it's hard to believe, but the bottom line is that the longer it takes a website to load, the higher the chance that the visitor will close the tab. Incredible.

So you should do everything possible to ensure that a website is delivered and, above all, displayed as quickly as possible. Apart from the fact that you should make sure that elements in the visible area are rendered first and certainly not flip back and forth while loading, another factor that can be easily influenced is keeping the number and the size of the required resources like stylesheets and JavaScript as small as possible.

The AssetCollector has been integrated with TYPO3 10.3. With this, scripts and stylesheets in Fluid files can be added to the rendering process with the ViewHelpers f:asset.script and f:asset.css. They behave similar to the renderAssetsForRequest already added in 8.6, with which you could render the corresponding code via the two Fluid sections HeaderAssets and FooterAssets.

The key difference is that, as the name suggests, the AssetCollector first collects the stylesheets and scripts and then only includes them once in the rendering. This means that I can reference the same JavaScript file in various Fluid files with the same name, which I need for example for a slider, but which is then only stored once in the document using a script tag at the end of the document.

Another advantage is that in this way you can ensure that only required resources are sent to the browser and not a JavaScript plugin for an accordion, which is not rendered on the page. Of course, this negates the concept that you always send the same resources to the browser so that it no longer requests them on the second page because it then takes them from its cache.

But with the simultaneous use of HTTP/2, which ensures that the resources for rendering the website are delivered to the browser before it even knows that it needs them, a speed advantage is still achieved in conjunction with the small data size and is especially noticeable in a faster rendering of the page. It is not at all bad that the resources are not integrated into the concatenation or compression process of TYPO3, as you were used to when you integrated your resources using TypoScript.

And so you have already made a few more visitors to your website happier.
And yes, I know, I have unfortunately not yet activated HTTP/2 on this page. It's not me. I'm sorry.


Learned something again and more

I always plan to do more with this blog. To tell something and perhaps give some input to others that will help them. Like the other tens of thousands of blogs and websites I can learn  from every day.

The past few weeks I have been quite offline during my free time. We have build a new terrace, which was already planned when we moved into this house a few years ago. At that time, I just didn't think we would do it all alone.

Next to building and plastering a wall (at least 3,5 x 2 m in size), the extraction, the gravel, pulling of the grit and cutting the plates I've learned that there is simply no need to ask a craftsmen. If you ask how to do one or the other, you get two or three answers which are obsolet one week later. Almost like developers.

And then I taught myself how to solve a Rubik's Cube. My little son brought them in and actually wanted to learn it too. Because I can't help him, I had to have learn it by myself and so I can now solve the cube in a little bit over two minutes with the beginner method. If I will learn other algorithms to solve it in under a minute... I do not know yet.

I will start learning again for the certification of a TYPO3 developer (TCCD). I was able to extend the TCCI certification by one year last Friday, whereby I think that the procedure is worth considering. Just because I took part in a presentation of the innovations of TYPO3 10, which I held in my department in a similar way shortly after its appearance, I have collected a lot of suggestions, but I don't master them. Perhaps this is because I was one of the last ones where the certification is normally valid for three years, the new certificates are only valid for two years.

For the preparations I work through the Exam Study Guide for the Official TCCD Certification of the TYPO3 Association (https://leanpub.com/typo3certifieddeveloper-en) and this time I decided for me to write a blog post for each topic or question that I don't answer correctly when I was studying, in which I then work on this topic. The best way to learn is to write a cheat sheet. There will definitely be some posts. ;-)

A weird time

It's been a weird time when nobody can say, how it will develop. Everyone is swimming.
And even if the effects can already be seen on the horizon and they will be hitting us hard, are all people (TM) kind of friendly to each other. Okay, except the people you get too close to when shopping. They look pretty angry. Or fearful.

Where no man has gone before...

The appearance of Bladerunner on gog.com today made me slightly confused, but I am sticking on my plan, to play both Star Trek adventures. The winter is here on the calendar and maybe I will find some time over the holidays.


How can you only live without a shell?

Hello, my name is Stephan, I'm in the beginning of my fourties and I'm developing under Windows.This is how I would introduce myself to the anonymous developers. After twelve years with macOS I must occupationally get along with Windows since middle of this year. What is going well now, because Windows isn't more bad than macOS or Linux. And the other are not better. Only different.
You realize, I'm in the phase of denial.

But honestly, what do I really need? An IDE (PhpStorm) and DDEV as configuration software for Docker. And a shell.
And the last one is missing under Windows. cmd.exe and the Windows PowerShell can't belong to iTerm2 with Oh My Zsh. And also after several months I'm crying after my shell under macOS. I have by now found a replacement with ConEmu and Oh My Posh but a PowerShell really does not feel so good in comparison to zsh. But there is also the Quake mode with ConEmu.
