Stupidity=Collissions et.al....

this is one stupid action i have to learn and unlearn. i recently set up a semi sub network in the office so i got a hub and pcs..there were two connections comming out from one of the hub connected in our open bay rack ..one was crossover (i did this just last week) and the other was straigh through (i knew it was there) so out of excitement i plugged all cabels from the pc and the two cables to the hub turned on the hub and......boom problems start flowing in. first internet was down the proxy server hangs. other pcs connected to our novell server starts logging off ..and worst offices starts calling staing that they cannot connect ..so i asked our MIS head ( hes been with the school for almost 10 years now handling the whole system before we took over) and started analyzing the error.. one sign we saw was the utilization was running at 98% and no pcs are connected ..looking for clues we stared at the fiber optic hub handling the backbone..and bam the collision error indicator is blinking fast informing us there is a problem ..out of nowhere my thoughts brought me to the straight through cable connected to the hub..immediately unplugging it brought the chaos down..whew!!!!!!!!!!

After doing some time reading and studying the library, I paused and decided it was too complex for my requirement. Using WF would be an overkill and the fact that it has, a rather, steep learning curve, there has to be another option. My mind toyed with the idea of developing a simple workflow library myself. It would be a learning experience but it might end up consuming a lot of time. Why reinvent the wheel? So I started querying the inte

Hiding Unwanted Python Folders and Files in Visual Studio Code

Visual Studio Code is a universal editor and pretty good at it. However, the explorer view maybe cluttered with the automatically generated folders and files confusing developers. Python is no different. Below are example files and folders generated by Python. The __pycache__ folder and *.pyc files  are totally unnecessary to the developer. To hide these files from the explorer view, we need to edit the settings.json for VSCode. Add the folder and the files as shown below: Copy and paste the lines below : "**/*.pyc" : { "when" : "$(basename).py" }, "**/__pycache__" : true

With the advent of social media, the incidents has increased in numbers and the victims does not even know what is hitting them. For the past years, we have heard of  depressions and deaths because of this.
