(Tech) Get the reverb impulse response of a church

I recently recorded an impulse response of the reverb of a 14th-century church (more or less the footprint of the sound ambiance of the building). Here is how I did it.

Quite a lot of reverb, that's exactly what we want to catch with an IR!

Then, of course, we can do some cleaning, fade out, etc.


But what is this useful for? You can use this Impulse Response in any music production software (the VST SIR1 is quite good and freeware) , and make any of your recordings (voice, instrument, etc.) sound like if they were recorded in this church. This is the magic of convolution reverb!


Useful trick when you record your own IR: play sweep0.wav in the building instead of sweep.wav. The initial "beep" is helpful to see exactly where things begin. If you don't do that, as the sweep begins with very low frequencies (starting from 20 Hz), you won't know exactly where is the beginning of your microphone-recording. Once your recording is done, you can trim the soundfile by making it begin exactly 10 seconds after the short beep.

Browsers, please don't kill HTTP

I don't share Jeff Atwood's enthusiasm about HTTPS / encryption. What will happen if HTTPS becomes the standard and if HTTP is considered by browsers as unsafe?

It seems to me that then, the web will be separated in 2 worlds: professional websites who have cash for SSL certificates and a dedicated team to maintain the certification process ... and the average small webmaster who just has a shared hosting and a Wordpress. The latter will be slowly "pushed out of internet" with the threatening notice Not secure.

Even with the free Let's Encrypt initiative, maintaining HTTPS requires huge technicity, much more than what the average webmaster has.

Result: if HTTPS becomes the standard and normal HTTP is alerted by browsers as unsafe by default, this will slowly kill amateur content, citizen-powered content.

Welcome to even-more centralized internet. Be sure Facebook and other big content providers will like this.

"Comme un ciel sans nuage"

Here is some cool French pop we made with my lovely girlfriend:

Why I finally won't go for open-source analytics tool (for now)

You discovered Google Analytics a few years ago (a webmaster tool to see how many visits on your websites), and used it efficiently. But, you know, Google-centralized internet, etc. and then you thought "Let's go self-hosted and open-source!". And then you tried Piwik and Open Web Analytics.

I did the same. After a few months, here are my conclusions.

Open Web Analytics has a great look, close to Google Analytics, but every week, I had to deal with new issues:

Nearly 250 MB analytics data in 2 weeks (for only a few small websites), this means more than 6 GB of analytics data per year in the MySQL database! ... or even 60 GB per year if you have 100k+ pageviews. That's far too much for my server. This was (nearly) solved by disabling Domstream feature. (Ok Domstream is a great feature, but I would have liked to know in advance that this would eat so much in the database).

I'm not saying OWA is bad: Open Web Analytics is a good open-source solution, but if and only if you have time to spend, on a regular basis, on configuration issues, which I sadly don't have.

I tried Piwik very quickly. It really is a great project but:

So, conclusion:

Analytics, unsolved problem.

I'm still looking for a lightweight self-hosted solution. Until then, I'll probably have to use Google Analytics again.

PS: No offence meant: most of my work is open-source too, and I know that it takes time to build a stable mature tool. This post is just reflecting the end-of-2016 situation.

bloggggg

Many things begin with

Let's start a new notebook!

(Well sometimes the notebook is abandoned after 3 pages, but hmm, let's not think about it). Writing helps to know what you want, what you don't want, and what you've done so far. So, like every one, I decided

Let's start a blog!

Then I looked at many blog generator tools, and I noticed it would be faster to actually write it myself in PHP, rather than downloading every existing solution and pick the best (so hard to make a choice). So I started yesterday evening, and today it's published:

blogggggg, a blogging platform.
