Like many other anti-depressant Zoloft is selective serotonin reuptake inhibitor...

The other way to treat this is by increasing level of serotonin...

Seeds of Griffonia simplicifolia contain a lot of 5-HTP, a precursor of serotonin..

It's non-patentable so I guess it won't be as popular as patented psychotropic drugs anytime soon..

Yes, thanks to Joyent, who opensourced smartdatacenter the software they use to run their public cloud...

The hypervisor is SmartOS, it is based on Illumos (fork of opensolaris)..
It has ZFS, Dtrace, Zones (think virtualisation with bare metal performance), crossbow.. and KVM as they ported it..
You can run SmartOS instances inside Zones, and even Linux instances (by way of ABI translation), or any OS using KVM,
And even present you datacenter as an elastic docker host, as they implemented Docker API in SDC.. (sdc-docker aka Triton)

I'm currently evaluating it, so far I'm impressed..

Here are the github repository and the docs

They are using their own Illumos-derived distribution, SmartOS, which combines greatest features inherited from Solaris: ZFS, Zones, Dtrace, crossbow...

It run SmartOS containers and Linux containers (via ABI translation), alongside VMs (using their port of KVM), everything being encapsulated into Solaris Zones..

They claim to offer better performance by removing some virtualization layer (and because of the supposed superior performance of their SmartOS hypervisor), and better security because they use solaris Zones, crossbow network virtualization..

You can even use use Dtrace inside Linux Containers..

They implemented Docker API at the datacenter level (via their SmartDatacenter software they opensourced in 2014), the data center is seen as a single, elastic Docker host. Everything is opensource


A preview is available, on-premises or as an hosted service.

Are SmartOS and the solutions built on top of it hidden gems, wrongfully ignored because not being Linux ? A better platform to run Linux than Linux ?

Is this a breakthrough Docker-Wise ? Or an attempt of a niche-player to grab some attention ?

What are the comparable offers running on Linux ?

Our president François Hollande made promises:
Starting September 2016, every highschooler will get a tablet beginning from the 5th grade (typically aged twelve)

Another promise, they will also learn to code.
Great .. but why give them a tablet and not some other device that would allow them to apply what they learnt..

We citizen are told again and again that there is no money, but there is money for buying gadgets..
We are going through the same mistakes that were done years ago in other countries...

2 years ago my son was 3 years old and beginning to go to school, and guess what was in the classroom ? A fracking interactive whiteboard. I have serious doubts about the educational benefits, especially for young childs. Of course teachers weren't even formed..

But, you know, our governments have no money..

One point that is not in the original Guardian article is that this is a proposal only, and a proposal that only applies to French companies that are part of the "Syntec" work agreement.

And it only applies to 200 000 workers whose worktime is not counted not in hours but in days (forfait jour), not one million..

That means they can work much more that 35 hours / week.

The limit being the labour law, ie: you must have rest period of at least 11 consecutive hours between each day of work and 35 consecutive hours each week. (so they can theorically work up to 88 hours in a week)
The modification to the agreement implies that during these mandatory rest periods the worker has to disconnect from work email, remote access.

Seems fair to me..

As a french speaker I am ashamed at the poor level of english reading level of most people in IT, even after five years in college..
A true IT professional should be able to read technical documents in English, which is the de facto standard language for CS ..
One complaining about not being able to read English, needs to be told he'll be doing a great favor to himself by improving his english level.

Recently, physicists Ronan Keane and Wei-Ming Zhang wrote a paper and studied on antimatter propulsion. Their latest results from computer simulators have shown that at least one key component in creating a working antimatter propulsion engine is that of highly efficient magnetic nozzles. Their studies have shown that these nozzles need to be efficient and that it is feasible to make them this way using our current technology.

Keane and Zhang also outlined how the particles would avoid a matter/antimatter annihilation as they exit the engine. Their technique relies on charged pions that result from proton-antiproton collisions. A nozzle that emits a strong magnetic field could channel the emitted charged particles into a focused stream of charged pions accelerating them to make an even stronger thrust.

Past calculations showed the nozzle's efficiency was only 36 percent, but Keane and Zhang redesigned the nozzles to be 85 percent efficient, making the a speed of around 70 percent the speed of light possible, given a pion exit speed of 80 percent of the speed of light. Such a speed gets us to Proxima Centauri 4.3 light years away in 6 years."
