Since I've started using StackOverflow, I've always loved their text editor (the one you use when writing a question/answer), because it supports Markdown syntax (a very elegant markup language to add bold, italic, titles, links, itemization, etc.), and even MathJax (which is more or less LaTeX syntax in the browser). I've always wanted to use such an editor for my own documents.
After some research, I found a few existing tools, but:
- half of them don't support LaTeX / MathJax (for math formulas)
- some of them do, but have a 1-sec delay between keypress and display, and I find this annoying, see e.g. StackEdit
- some of them have annoying flickering each time you write new text, once math is present on the page
- most of them are not minimalist / distraction-free enough for me
Let's go and actual build one! Here is the result, Writing:

Have you ever spent more than 1 second wondering:
"How do I get on my computer this photo I just made with my phone?"
"How do I get this PDF from my computer to my phone?"
Then you probably thought "Let's use Dropbox! ... oh no I'm not logged in on my phone, but what is my password again? Well, let's send the file to myself via email! Maybe I should just use a USB cable... but where is my USB cable again?"
Yopp is a solution for this problem, that you can easily install on your web server.
Thoughts about user experience & user interface design
This tool - Yopp - requires a total number of 7 actions to get the work done:
Open browser on phone [1 tap], Open Yopp page [1 tap if it's in the bookmarks], UPLOAD [1 tap], Choose file [1 action] Open browser on computer [1 double click], Open Yopp page [1 click if in bookmarks], DOWNLOAD [1 click]
I'll be happy to switch to another tool if one requiring less actions exists.
I noticed that my likelihood/probability to use any tool (all other things being equal) is more or less proportional to
P = 1 / a^2 (*) where
a is the number of required actions/user inputs. If the number of required actions is doubled, the likelihood to use the tool is divided by 4.
Thus, even if it might sound obvious, one key element for a good user interface is to minimize the number of user actions to get a task done. If not, the user might unconsciously remember that the interface is unnecessarily complicated to use. He will then forget about the product, and look for another solution. (OK this is probably what will happen for you with Yopp if you don't have a web server already!)
As an example, I'm sure I'd use my city's bicycle sharing system Velo+ much more if I could take a bike by just swiping my card on the bike station's card reader (this is technically possible). Instead we have to: Tap on a screen (1), Choose "Subscribed user" (2), Swipe the card (3), Choose "Rent a bike" (4) (this one is particularly unuseful), Accept conditions already accepted many times before (5), etc. at the end it requires at least 12 actions! Any user who has done it at least once will process this data (required amount of inputs) and will probably make the choice of not using it for short distance trips.
It would be interesting to get more statistical data about the empirical result (*), this will be discussed in a future post.
This topic has been present in my thoughts for a long time, probably years:
“How to be able to think/write about lots of unrelated various topics, and still have a way to look at the big picture of what you’re doing?”
Here is my contribution about this:
- bigpictu.re, a ready-to-use infinite notepad (infinite zooming and panning)
- A standalone version of 1. (so you can take notes offline) is also available here: bigpicture-editor
- AReallyBigPage, an infinite collaborative notepad. It has been a real chaos once hundreds of people joined in. Probably internet’s deepest page ;)
Such an interface is called a Zooming User Interface (interesting reading: The humane interface by Jef Raskin, one of the creators of the Apple Macintosh), and strangely, ZUI has been very few used in modern interfaces.
As of 2017, nearly every software interface uses a 2D, or even a 1D navigation process: a web page only offers two scrolling directions: north and south. Even nowadays's apps famous for their "new kind of interface" still use a 1-axis navigation: "Swipe left or right".
Is there a future made of new interfaces?
After having tested many open-source website analytics tool, and haven't found exactly what I was looking for, I started a minimalist project (coded in PHP) that only does this:
number of visits per day
- display the referrers (i.e. the people who have a link to your website)
If you're looking for a tool lighter than Piwik, Open Web Analytics or Google Analytics, then TinyAnalytics might be what you're looking for.
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:
- first I discovered that a gigantic table was growing in the MySQL database:
| owa | owa_request | 4.44 | | owa | owa_click | 5.30 | | owa | owa_domstream | 238.28 | +--------------------+-------------------------------+------------+
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).
today I've seen that a new table in the OWA database was very big (747 MB in a few weeks!)
| owaa | owa_queue_item | 747.92 | +--------------------+-------------------------------+------------+
- some other issues: login impossible from Chrome in certain situations, unique visitors count wrong when using PHP tracker (sometimes, each new visit / refresh of the page is considered as a new visitor), time-range menu not displayed at all (display stuck on 1-week range) in some cases, etc.
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:
it doesn't offer a direct view of what I was looking for out-of-the box, i.e. clear charts for every website à la Google Analytics (I can't really describe what's the problem, but the user interface isn't handy for me)
- maybe there's an easy fix for this, but the interface is very slow
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.
