Lyx pour auteurs: un premier post

J'ai aidé récemment une auteure à utiliser Lyx pour la rédaction de son roman, et son expérience a été si positive qu'elle a commencé une série de post à ce sujet à destination d'auteurs (non informaticiens). Le premier post vient d'être publié, mais d'autres suivront!

Create and deploy a Jekyll site to Github page in 5 minutes

As I was looking for a simple way to publish documentation but still ensuring a long term availability and full control of the content, I went for a self-developed solution based on Jekyll and YUI Grids.

If you're looking for a solution to rapidly be able to deploy content on Github pages with Google Analytics and Google Search integrated, Jekyll Base might be for you.

All reasoning and information on Nsa.be, and code available on Github.

About Virtualbox, S3, time drift, 403 reponses

I was working on the FileAttachment code of myowndb.com in a virtualbox debian guest, when all request sent to S3 got the 403 Access Forbidden reponse, even code that was working fine in production. The good thing was that the production server still worked flawlessly, but I really asked myself what I had changed to break my code.

After checking my credentials, the code, trying with S3cmd and getting the same problem, I found a forum thread where having the wrong time could cause that problem.

And that was indeed the problem! My time had drifted 15 minutes, so I was sending out request with a timestamp in the future.... An ntpdate later, everything was working fine. Phew!....

From OO to List style: my notes

I've continued development with Clojure and Jwt, and I got stuck: how do I implement my app without class definition and instance variables? It's not hard, but I had to get used to it. You'll find my notes here. Feedback welcome!

Nokia N900: I'm not sure I want it

Today Nokia unveiled specs of their next internet tablet: the N900.

No, I still haven't found my PDA-phone, or do they cal that a smart phone nowadays? But I've bought the N810 in the meantime, and that was a big disappointing experience: the addressbook application was horrible. Of course, Nokia calls it an internet tablet, and for a good reason. But sadly Nokia seems to think that an internet tablet is not made to help contact managment.

When you see the N900 page, there's a lot of talk about internet and network technologies, but not a word about contact management or calendar. That a bad sign, and I fear the situation has not improved a lot.

I'll wait a bit more to see how Android phones evolve. They seem to have very interesting stuff going on....

Tmdtc Interview from this morning

Here is the radio interview (in french) I did this morning:

Sunday 2 August 2009

The Million Dollar TagCloud on the radio

Tomorrow, monday 3 august, I'll give a short interview about TheMillionDollarTagCloud.com on PureFM, a national french-speaking radio. It will be a short interview of about 3 minutes. Even though it is the holyday period, this should give a boost to the project.

If you want to have your tag online before the interview, book it now and I'll put it online in time.

Facebook App for TheMillionDollarTagCloud

I have finally finished the TMDTC Facebook App for TheMillionDollarTagCloud.

For those who don't know, TheMillionDollarTagCloud ( aka TMDTC) is my attempt at selling for $1 million worth of tags, and I'll distribute $100.000 if this works out.

To make a chance to win these $100.000, you just need to register and then click on tag, or publish a tagcloud on your own page (like I did on this blog, see right column) and encourage people to click on your tag cloud.

Each click recorded gives one chance to the clicker and to the publisher of the tagcloud on which the click occured to win the 100.000$.

And now, there's one more way to augment your chances at winning these 100.000$: the TMDTC Facebook app, which lets you publish a tagcloud on your Profile, and share it with your friends.

I hope you join and spread the word around. I really want to distribute these 100.000$! :-)

Next week will take place the Profoss event on legal impact of open source licenses and despite a very interesting that should make it one of the most interesting Profoss event until now, registrations are in the low-end of what I hoped.

My new professional website

It's been one year now that I started work as self-employed, as you could read on this blog. And now I finally took the time to make a website to present my professional activities: http://www.nsa.be is now my online vitrine.

The content of the website is currently available in english and french, with the dutch version to be finalised next week.

I expect most of my future blog posts about FOSS to be made on the website's blog.

NSA.be is a domain name I've had for years without using it, and those three letters actually have links to what I do: Networking, Software, System Administration, Advising, Support, Solutions, Applications. Yes, I know, I'm not a good salesperson.... Forget about the meaning, just remember the address ;-)

My take on short URLs

Shortening URL services are all the rage these days. Reading Robin's report yesterday on again new services made available, in which he mentions a service developed over a week-end, I wondered what could be the next step....

As the fast-food services of URL shorteners are evaluated to be worth millions of dollars, I thought my service proposing hand-crafted URLs and developed in 2 hours wouldn't be more ridiculous than those valuations.

So here it is: http://hé.pl. Be sure to take a look to the added value of the service!

Oh, and I'm open to investments based on a proper valuation of this revolutionary service! Just let me know :-)

Linkedin: Locked out!

It's been months now that I'm locked out of LinkedIn. their customer support say they're aware of the problem, but don't explain what is causing the trouble, nor when it will be corrected.

The problem is that I have requests to join the Profoss group waiting for approval, as wel as multiple invitations to connect. With an event coming in two weeks, it's a tool I could have used for promo!

If they hoped to make me a paying customer, well, it's not the good approach!

Anyway, if I don't answer to your invitation or approve your Profoss group membership, just know that's it's not because I don't appreciate you, it's because I am

Generate a random string in Clojure

In my quest to learn Lisp, I discovered Clojure, a List inspired language on the JVM. I really like it and hope to be able to use it more and more.
Here's a code snippet to generate a random string in Clojure. This is something I end up using a many projects. This is a version that is not made to be the shortest, but the most readable. And as you can see, access to Java's classes and libraries is very easy:

:use java's random generator
(def random (java.util.Random.))
;define characters list to use to generate string
(def chars
(map char (concat (range 48 58) (range 66 92) (range 97 123))))
;generates 1 random character
(defn random-char []
(nth chars (.nextInt random (count chars))))
; generates random string of length characters
(defn random-string [length]
(apply str (take length (repeatedly random-char))))

Suggestions to improve the code are welcome, I'm still a newbie in Lisp-style programming and Clojure!

Linkedin problems

The last weeks I've had serious problems to access linkedin: I can't accept group memberships, send invitations, accept invitations, etc: when attempting this, the browser waits and waits and doesn't get any answer from the server. And today I can't even access their homepage:

Very annoying...

UploadForMe open to all

I just lifted the need of an invitation to register for an UploadForMe account at http://www.uploadforme.com/a/signup.
With such an account, you can discover how the platform works, as you can upload files (one at a time currently) and then send them to Picasa, Flickr or Youtube.
Importing large number of files by sending a DVD is still limited to users contacting me about it.

Uploadforme open to beta testers with 4Gb of free transfer

Finally, Uploadforme.com is opening the gates!

The idea of the service is simple: help you bring your digital content online. You send it on DVD, we put it online on our server from where you can then import it in the online service you want (currently supported: flickr, picasa, youtube).

Let me know if you want to be part of the beta phase, we propose to put online 4Gb of data from our beta test users for free.

Using the clipboard in vim

How many vim users know that you can copy from and paste to the clipboard?
It's even very easy: use the register +
To use a register with a copy or paste command, you specify it by typing " followed by the register name.
So, to copy to the x register and the clipboard:
and to paste from the x register:

I think this would be best illustrated by a screencast. Anyone interested in vim screencasts? Should I take the time to do some vim screencasts? Let me know.

BDO darts world championship over

The 2009 BDO Lakeside World Professional Championship, a one week darts competition, ended today, with the title going to Ted Hankey after a great and dramatic final, decided in the final set.
Tony O'Shea lost his 4th final of the year, sad for him :(

Before you laugh that I'm looking darts competition on television, did you ever watch a match? Everyone I've talked about it laughed at me first, but got caught when watching. I've started looking at it during my exams as univ, and try to follow the championship every year. I dont watch other competitions, so I can't comment on them, but the BDO world championship at the Lakeside is something you should give a try, usually on BBC2 around this time of the year. That will be for 2010 though!
