Posted on by

It is really hard to find nice and fun pregnancy clothes, there are some existing shops with limited choice, only 1 or 2 fun stuff that are really classical and as this market have at least half of the world population, we could imagine that better thing could be created. More over market price is really expensive and there is a big area for a cheap, young, fun brand for this kind of clothes. As you only need to ware them 9 month, quality is not the major point…

As all the idea in this category, feel free to comment, and develop, if you become rich with it … don’t forget to help me paying my house !

Idea of the day – scancore reader for fridge

Posted on by

The purpose of this idea is to have a mobile scan code reader attach to the fridge to scan each of the product we need to replace once finished. I’m sure that this idea is not new, but the concept is to have an embedded system able to order the full list directly to online shops. The system must be complemented by a mobile application to complete the list and validate the shopping list.

When your need to replicate data from one server to another, the rsync solution is usefull. It works over ssh and you do not really have any specific thing to configure. Here are the options to be used to get a full copy with all the rights and ownership replicated :

 rsync -P -azc src_files_or_dir user@dest_server_ip:/dest_server_dir/

This works if the destination server have ssh open on port 22. If it is not the case another set of options is required :

rsync -P -azc -e "ssh -p dest_port" src_files_or_dir user@dest_server_ip:/dest_server_dir/

Hope it’ll help ! fro sure it will be a good reminder for me 😉

More and more, companies are going to SaaS (Software as a Service) solutions. They offer a quick and generally less expensive solutions compared to standard software approach.

Private Copy tax

As you may know, in France as in a lot of other countries, we are  paying a Tax for private copying, this tax is printed nowhere like State Tax but it exists as a part of each of the storage product we are buying, even if this product is never use to store any copy of your music & video. This is also payed to store your original Mp3 like in an iPhone, iPod for example. This tax does not help the gaming and software industry even if this is where it made sense to apply it some decade ago before it has been locally destroyed.

This tax is apply to many device and grow regarding the size of the storage space. The price per GB is reviewed yearly and generally become higher and higher. The following Graph (copied from numerama) is showing how many euro has been transfered from consumer to music & movie industry in France during last 25 years.

 

 

 

 

 

 

 

This is about 181M€ / year actually with an interesting growth which is also something like 3€ per French and also about 7€ per family. This money is going directly to the artists and it is like, according to different sources,  if we buy 7 album per family per year. In my point of view it is more than the average.

Then, coming the question ? what is the right i get for this price… actually ?
