## Typing every day…

Good things about a keyboard is to use it regularly. Don’t you enjoy it?

More seriously, I used to have a diary. A leather-bound notebook. Thing is, the times when I wrote were quite random, and a year could pass without me writing anything. Why? Maybe because it was much of a constraint for something I would rarely or never look back to. Plus, no matter how I liked the use of a good ol’ fountain pen, it was quite a hassle and did not fit mobility.

So I searched to go mobile and checked what was available on the internet. This is how I met 750words. But what is it?

Basically, it is a website which encourages you to write at least 750 words every day (now you get the name). How can they? Well, streak points, badges, … Looks stupid, maybe, but I know my weak points, and I know from video games I like to collect such awards, so I just dived in.

What features can you expect besides these awards? Well, first, for geeks, Markdown is fully supported.

For others, each day, a graph is drawn, analyzing the content of your writing. Well, analysis by automated dictionaries and algorithms are more or less accurate, but I think you can’t help and watch what today’s graphs are like, or how you did since you began on 750words.

It has been two weeks since I began on 750words and I have not broken the streak yet. For now, I use it as a diary only, but I guess time will come when I have nothing more interesting to write. So how not to break the streak? Some know I would like to be able to write, and I am hoping for the exercise of writing everyday to make it easier. Only imagination is the weak point right now, but this could become a challenge for short stories, and may lead to even better after. Let us wait and see.

Just a final word: if you are looking for an online diary but do not like the constraint of having to write everyday, 750words’ author publicizes about neat-looking Penzu, which has the only brick I lack for total mobility with 750words: mobile apps.

## How to implode iterables in Java

The PHP implode function can be quite useful, but no equivalent exist in Java that I know of. Luckily, you can quite easily implement your own.

# Implode arrays

This is actually pretty straightforward. Here is what you need to do:

Yeah, I declared this array so that it can contain just any kind of objects. No problem when passing StringBuilder.append(Object), since it will use String.valueOf(Object), returning either the null string if object is null, or the .toString() of the instance.

But arrays in PHP behave more like lists, so why not extend this method to Java Lists?

# Implode lists

Using an Iterator is great. It avoids using the .size() to count the elements of the list, and does not require an explicit loop with the .get(int).

Plus, since Iterator applies to all collections, you can extend the method…

# Implode collections

Alright, now it works for lists and sets. Just remember the order of elements is not garanteed if you use this method with a set.

## The Optimus keyboard might hit the market

I guess you remember about the Optimus keyboard, right? Each key is a screen, thus allowing to change the keys according to the application you use. Well, the people behind it were at CES 2013.

And what is the announcement, then? That they succeeded in making it cheaper, with the Optimus Popularis. The solution? Instead of making each key a screen, make each key transparent, and put a unique screen under the whole keyboard.

Now, how much cheaper does that make it? The announced price tag would be \$700… It might hit the market this summer, we’ll see then if the success is here

For full advice, see news on the net. They are quite numerous about CES, and you might find some from people who actually tried the keyboard…

## KP Dock Icons released

I previously posted about a KP Dock Icons project. For those who have not seen the post from the newly created KeyboardPlaying Twitter user, I published the first batch of icons.

They are now 47 icons available on PNG Factory.

I am not quite done yet, but do not know when I will be able to go on. The roadmap and requests are still open on Trello.

I will initiate a project page as soon as I have some time left… Meanwhile, do not hesitate to comment here!
