Description
openBalena VPN augments an OpenVPN server with the following components/features:
open-balena-connect-proxy is a http connect proxy that handles connections through the vpn to services on connected devices, used by external services such as balena-proxy
open-balena-vpn-api which consists of an internal API for handling authentication and tracking device state, and spawns openvpn server instances
haproxy used for balancing new connections between openvpn instances
libnss-openvpn is used to handle dns lookups of devices for connections via open-balena-connect-proxyExcel est un outil fantastique pour organiser et travailler sur des données, mais également pour les présenter. Il est notamment possible de réaliser des graphiques professionnels qui se mettront à jour directement lorsque vous changez vos données. Dans ce tutoriel, je vous donne tous les outils pour créer un graphique et le présenter de manière claire.
Chaque minute, nombreuses sont les tentatives d'intrusion sur l'ensemble des ordinateurs connectées à Internet. Parmi les attaques les plus virulentes, il y a bien sûr les tentatives d'accès SSH, l'exploitation de failles de sécurité sur des services Web (Wordpress, PhpMyAdmin ...) et l'exploitation des failles de sécurité sur des services contenant
Configure the X Server
To use NVIDIA's PRIME render offload support, configure the X server with an X screen using an integrated GPU with the xf86-video-modesetting X driver and a GPU screen using the nvidia X driver. The X server will normally automatically do this, assuming the system BIOS is configured to boot on the iGPU and NVIDIA GPU screens are enabled in /etc/X11/xorg.conf.d/nvidia.conf:
Section "ServerLayout"
Identifier "layout"
Option "AllowNVIDIAGPUScreens"
EndSection
If GPU screen creation was successful, the log file /var/log/Xorg.0.log should contain lines with "NVIDIA(G0)", and querying the RandR providers with xrandr --listproviders should display a provider named "NVIDIA-G0" (for "NVIDIA GPU screen 0"). For example:
Providers: number : 2
Provider 0: id: 0x221 cap: 0x9, Source Output, Sink Offload crtcs: 3 outputs: 6 associated providers: 0 name:modesetting
Provider 1: id: 0x1f8 cap: 0x0 crtcs: 0 outputs: 0 associated providers: 0 name:NVIDIA-G0
Configure Graphics Applications to Render Using the GPU Screen
To configure a graphics application to be offloaded to the NVIDIA GPU screen, set the environment variable __NV_PRIME_RENDER_OFFLOAD to 1. If the graphics application uses Vulkan or EGL, that should be all that is needed. If the graphics application uses GLX, then also set the environment variable __GLX_VENDOR_LIBRARY_NAME to nvidia, so that GLVND loads the NVIDIA GLX driver.
Examples:
NV_PRIME_RENDER_OFFLOAD=1 vkcube
__NV_PRIME_RENDER_OFFLOAD=1 GLX_VENDOR_LIBRARY_NAME=nvidia glxinfo | grep vendor
Finer-Grained Control of Vulkan
The NV_PRIME_RENDER_OFFLOAD environment variable causes the special Vulkan layer VK_LAYER_NV_optimus to be loaded. Vulkan applications use the Vulkan API to enumerate the GPUs in the system and select which GPU to use; most Vulkan applications will use the first GPU reported by Vulkan. The VK_LAYER_NV_optimus layer causes the GPUs to be sorted such that the NVIDIA GPUs are enumerated first. For finer-grained control, the VK_LAYER_NV_optimus layer looks at the VK_LAYER_NV_optimus environment variable. The value NVIDIA_only causes VK_LAYER_NV_optimus to only report NVIDIA GPUs to the Vulkan application. The value non_NVIDIA_only causes VK_LAYER_NV_optimus to only report non-NVIDIA GPUs to the Vulkan application.
Examples:
NV_PRIME_RENDER_OFFLOAD=1 VK_LAYER_NV_optimus=NVIDIA_only vkcube
NV_PRIME_RENDER_OFFLOAD=1 VK_LAYER_NV_optimus=non_NVIDIA_only vkcube
Finer-Grained Control of OpenGL
For OpenGL with either GLX or EGL, the environment variable NV_PRIME_RENDER_OFFLOAD_PROVIDER provides finer-grained control. While NV_PRIME_RENDER_OFFLOAD=1 tells GLX or EGL to use the first NVIDIA GPU screen, __NV_PRIME_RENDER_OFFLOAD_PROVIDER can use an RandR provider name to pick a specific NVIDIA GPU screen, using the NVIDIA GPU screen names reported by xrandr --listproviders.
Examples:
NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia glxgears
NV_PRIME_RENDER_OFFLOAD_PROVIDER=NVIDIA-G0 GLX_VENDOR_LIBRARY_NAME=nvidia glxgears
__NV_PRIME_RENDER_OFFLOAD=1 eglinfo
NV_PRIME_RENDER_OFFLOAD_PROVIDER=NVIDIA-G0 eglinfo
Troubleshooting
After starting the X server, verify that the xf86-video-modesetting X driver is using "glamoregl". The log file /var/log/Xorg.0.log should contain something like this:
[1272173.618] (II) Loading sub module "glamoregl"
[1272173.618] (II) LoadModule: "glamoregl"
[1272173.618] (II) Loading /usr/lib/xorg/modules/libglamoregl.so
[1272173.622] (II) Module glamoregl: vendor="X.Org Foundation"
[1272173.622] compiled for 1.20.4, module version = 1.0.1
[1272173.622] ABI class: X.Org ANSI C Emulation, version 0.4
[1272173.638] (II) modeset(0): glamor X acceleration enabled on Mesa DRI Intel(R) HD Graphics 630 (Kaby Lake GT2)
[1272173.638] (II) modeset(0): glamor initialized
If glamoregl could not be loaded, the X log may report something like:
[1271802.673] (II) Loading sub module "glamoregl"
[1271802.673] (II) LoadModule: "glamoregl"
[1271802.673] (WW) Warning, couldn't open module glamoregl
[1271802.673] (EE) modeset: Failed to load module "glamoregl" (module does not exist, 0)
[1271802.673] (EE) modeset(0): Failed to load glamor module.
in which case, consult your distribution's documentation for how to (re-)install the package containing glamoregl.
If the server didn't create a GPU screen automatically, ensure that the nvidia-drm kernel module is loaded. This should normally happen by default, but you can confirm by running lsmod | grep nvidia-drm to see if the kernel module is loaded. Run modprobe nvidia-drm to load it.
If automatic configuration does not work, it may be necessary to explicitly configure the iGPU and dGPU devices in xorg.conf:
Section "ServerLayout"
Identifier "layout"
Screen 0 "iGPU"
Option "AllowNVIDIAGPUScreens"
EndSection
Section "Device"
Identifier "iGPU"
Driver "modesetting"
EndSection
Section "Screen"
Identifier "iGPU"
Device "iGPU"
EndSection
Section "Device"
Identifier "dGPU"
Driver "nvidia"
EndSection

"Hi!
Some people may prefer a desktop solution for OTA DFUing micropython.zip. I found that https://github.com/dingari/ota-dfu-python works well for this:
sudo $HOME/ota-dfu-python/dfu.py -z $HOME/wasp-os/micropython.zip -a D6:62:01:XX:XX:XX
You may want to update your docu accordingly.

PS: Great work BTW!"
The microservices-honeymoon period is over. Uber are refactoring thousands of microservices into a more manageable solution [1], according to Kelsey Hightower monoliths are the future [2], and even Sam Newman says that microservices should never be the default choice, but rather a last resort [3].
What is going on here? Why so many projects became unmaintainable, despite the microservices’ promise of simplicity and flexibility? Or maybe monoliths are better, after all? In this post, I want to address these questions. You will learn about common design issues that turn microservices into distributed big balls of mud, and of course, and how you can avoid them.
(repost because my other discussion is dead) So I am using Steam on Linux Mint 18.3 Sylvia, and recently I got this error message when steam starts up: "glXChoose visual failed", and it won't start. If I run steam in terminal: Running Steam on linuxmint 18.3 64-bit STEAM_RUNTIME is enabled automatically Pins up-to-date!
