I bought Lego EV3, and plan to use Lejos project.
I follow the very good Getting started with leJOS EV3 howto to create SD card, configure eclipse and so on.
But it’s very boring to turn off EV3, copy program to SD card, then restart EV3 to run it.
As explain in Creating a bootable SD card howto section, using a wifi dongle improve greatly those steps.
However, setup wifi connection using EV3 is really annoying, especially if you use a complex PSK, and impossible if you use hidden SSID.
As explain there, 88.blocklist.zap is Microsoft maintained black-list.
Because of its operating mode, this blacklist can’t be monitored from common online tools like MXToolbox.
However, there is a Microsoft live online tool to query status of your IP, and may be used to follow blacklist IP status, as other anti-spam and antivirus tools implemented on Microsoft online applications.
My Laptop is a Lenovo T420s with 8Gb RAM and a 7400 rpm SATA disk.
I’m using lots of virtuals machines, especialy for BlueMind development and clients projects, and sometimes my laptop is overloaded.
There is mainly 2 bottleneck:
Today I try to setup a DRBD mirror using a hard drive partition. My goal is to setup LVM over this DRBD device.
I’m running a Debian Wheezy, but it’s not so important in this case.
All works fine using DRBD documentation, which is very clear to setup this.
Except that I don’t use a logical volume as backing device for DRBD, but a simple disk partition (/dev/sda5 on my setup). And want to create a volume group using the DRBD device.
My problem becomes when I reboot…
Since I upgrade my Nexus 4 and Nexus 7 to Android Kit-Kat (4.4) from Jelly Bean, and use hangouts as my default SMS application, I received Hangouts messages (not SMS) with very long delay. Sending messages works fine.
I need to clear cache and data for Hangouts application on my devices to fix this.
Since one year now, I’m working on a great project named Blue Mind.
This is a professional groupware including mail, contact and calendar using new web technologies, off-line mode, mobile device synchronization and lots more stuff.
We want to offer a powerful but user and administrator friendly software.
A new attractive adventure !
Suite à l’arrivée du 4° opérateur mobile français, et aux forfaits proposés, j’ai pris la décision de migrer vers l’offre abonnés freebox à 15,99€ par mois.
Et ça y est, c’est fait depuis hier après-midi. J’ai décidé d’écrire ce post uniquement pour faire un retour sur le déroulement de la migration.
