<token>
); - optionally
/setdescription
and/setuserpic
.
- Add the bot to the chat/channel and note its id:
- add the bot to a new or existing chat or group - this is where your bot will send notifications to;

When it comes to assembly language, it isn't as hard as many people think. Fundamentally, you write short, human-readable commands for the processor to execute (your assembly code) and then use a tool (the actual assembler) to translate your code into machine-readable binary instructions. Unlike high-level languages, assembly language is very simple and doesn't have that many features. The difficulty is to deal with memory and build more complex flows (e.g. loops or I/O) from the simple primitives that the assembly language gives you.
CPUs usually have small, very fast storage available for the data that is used in its instructions. This kind of storage is much smaller but also much faster than the RAM and is called registers
. An x86 processor has a bunch of them to store generic data, manage the stack, keep track of the current instruction and other administrative inform
This is a story about how I tried to use Go for scripting. In this story, I’ll discuss the need for a Go script, how we would expect it to behave and the possible implementations; During the discussion I’ll deep dive to scripts, shells, and shebangs. Finally, we’ll discuss solutions that will make Go scripts work.
While python and bash are popular scripting languages, C, C++ and Java are not used for scripts at all, and some languages are somewhere in between.
Ubuntu, Fedora, openSUSE, CentOS, SUSE Linux Enterprise, Debian,... users can finally use Autodesk Fusion 360 in the Linux Browser now.
On Chromium 55.0.2843.0 I get NET::ERR_CERTIFICATE_TRANSPARENCY_REQUIRED
.
Just run this from your Mac terminal and it'll drop you in a container with full permissions on the Docker VM. This also works for Docker for Windows for getting in Moby Linux VM (doesn't work for Windows Containers).
docker run -it --rm --privileged --pid=host justincormack/nsenter1

Displays contents of /proc/net files. It works with the Linux Network Subsystem, it will tell you what the status of ports are ie. open, closed, waiting, masquerade connections. It will also display various other things. It has many different options. Netstat (Network Statistic) command display connection info, routing table information etc. To displays routing table information use option as -r.
Sample output:
Proto Recv-Q Send-Q Local Address Foreign Address (state)
