For several years I used Vstarcam software (IP Camera Super Client) on Windows to record video stream from my cameras. This software (I preferred specific version 18.104.22.1687) is quite reliable, though it produces video files that can’t be played by other video players. You can watch them only using this application. It was also painful […]
As I mentioned in the post about Cinnamon power management, I decided to give Linux a try one more time. It happened after I had tried to install Windows 10 and those installation continued the whole night. Moreover, there was no any progressbar or something during the installation of OS and especially during the installation […]
I describe a solution, which I use to make an http live stream (video player embedded into web page) from two Vstarcam surveillance cameras (C7823WIP and C7824WIP).
This post about my personal crusade against horrible power management in Linux Mint Cinnamon 18.2
I had been cursing this subsystem for two years and then found a workaround in 24 hours.
A few days ago I pulled my Acer C720 out of the nightstand and noticed that it has a strange shape…
It’s keyboard was bulged toward the screen so the laptop can’t be closed completely.
Battery was swollen.
After I have removed the battery everything seems to work well except the wifi. Wifi couldn’t connect to anywhere and somehow I understood that the problem is incorrect date in RTC. RTC really had some fake date in the far future. It seems that there is no separate CMOS battery in this laptop. And I was needed to find the way to fix it.
In my family we often used pieces of paper to write down a list for the next grocery store visit.
I think this is a common situation and many people are using such lists.
After some time I have begun to feel some inconvenience because sometimes I forgot to take these lists to the grocery or I couldn’t understand a handwriting.
So I decided to do a simple web service on my own web server, that will serve as a shopping list.
This is a post about my graduation thesis at the University. For now it seems simple and maybe not quite appropriate for such specialty as a physicist, but every measurement needs a scale. For an average student at those times and place it was a decent work and also these results were actually demanded by […]
Here I will describe a pattern that I used for a couple of years to pass filtering and sorting options from jqGrid to MySQL server.
JqGrig that is used here is simple. What I actually want to share is my two Perl subroutines – get_searchstring() and _get_filterops that allows to translate almost any filtering request from jqGrid to MySQL.
I can’t guarantee anything, you know, but these subroutines worked well for several years and didn’t manifest any glitches.
In the project of “internet vending machine” we used almost standard qwerty keyboard and standard PC, so we needed to have possibility to be able to switch off keyboard during reboot, to disable CTRL+ALT+DEL and so on. These functions with a decent quality, until the death of the project, had been performing by “the keyboard interceptor” device. Interceptor is a device that is connected between PC and keyboard for keyboard data filtering. Device also capable to receive from external sensors and transmit to PC via serial port some data, to control some peripheral devices , but it’s main task, which consumes the most of it’s resources, is keyboard data filtering.
When I studied at the university I found out for the first time about existence of watches that have altimeter, compass, automatic light switching and other cool features. I became sick with this kind of watch and desperately wanted to get one of them. The first such watch, that became known to me, was Casio […]
