In this video I am showing how to recover a dropped database, from the binlog files of a MySQL setup. The reason I am doing this video is because I had a situation when I had to do this very thing and I tried looking up on the internet how to do this, but I was having a hard time finding anyone who had gone through the whole process, so I ended up having to manually read through the documentation, in order to see how it could be done. The process turned out to be quite straightforward, so I thought it would be worth doing a video showing how to do it.
Node JS was the newest hot thing on the programming block a few years ago, but it has entrenched itself as the goto place for people who want an easy time of building web applications. Gone are the good old days when programmers used to produce high quality code and then debug it, because they were given the time to do these things, but Node JS was one of the development environments that helped to bring in the new slave programmer generation. Once Node JS became a success and the big companies realised that they could trick the new age programmers into this "new" way of coding, where they just endlessly produce code, without debugging it, we then ended up with other programming languages that now follow this release often and who cares about the bugs trend, like Rust and Go, which also come with the same endless dependencies that Node JS projects bring in with them.
In this video I am showing the suction performance of the Opolar Air Duster and Vacuum, when I am using it to clean some heavy dust of of the big fans on my pc. With th amount of dust I was trying to clean, an air blower would have made a big mess, so this is definitely a situation where a vacuum device comes in much more handy, than a device that would blow the dust all over the place.
This is just a video of me going through a wood near where I live, just so that I could test out a new Chinese torch that I had bought. The torch turned out to be very bright and it certainly did light up the pitch dark wood, as you can see in the video.
This is just a quick video that I am doing to show that you can have negative numbers in a switch/case statement, inside of a C program. The only requirement that I know of is that you must be using GCC to compile (which sensible person doesn't), because the GNU programmers obviously realised that they can't be in a position where their compiler is saying that they are not allowed to do something that is very useful. If GCC did not support this feature, then I would have to resort to typing a whole lot more unnecessary code.
If you are doing a fresh install of Windows 10 on a Lenovo X240 with the 1920x1080 touch display, then you should find that the majority of the drivers for it will be identified, but you will most likely find that there is one annoying device that is left behind and it should have a hardware ID of ACPI\VEN_BCM&DEV_2F09, with it also being located on the "Synaptics SMBus Driver". When doing a search for this identifier, the only place that had a proper reference for it was the Driveridentifier website, but of course the download link is a loaded one that passes information onto them.
Since it took me a while to finally find the right driver for this device and it looked as if there were not any other references for it in the Google search, I decided to include a clean version of the link to the correct driver. This is the genuine driver and it shows up with Lenovo as the Signed vendor when it is installed, with the unknown device also being converted to the correct one which is a "NFC SMBus Device", that is powered by a Broadcom driver. Below is the link to the driver.
00:01:00 Creating a qcow2 file for Windows 11.
00:02:10 Running the virtual machine.
00:03:30 Installing the virtio storage driver.
00:06:10 Installing Windows 11 onto the disk.
00:07:50 Time to boot into the main setup.
00:09:00 Going through the setup with no TPM error.
00:11:10 An error comes up during the setup, but a reboot fixes it.
00:12:25 Installing the virtio network driver.
00:15:50 Installing the QXL graphics driver.
00:17:40 Installing a browser ro check the networking.
In this video I am installing Windows 11 into Qemu and am showing how to install the virtio drivers, so that the disk accesses can be fast. This is also a Windows 11 that has had the hardware check removed, which shows that none of the standard code in it, actually needs the TPM. This shows that Microsoft has decided to switch to doing things like Apple, where they make up some lame excuse for why their next version of their operating system, needs some random hardware feature that is only in the newer computers that are sold. They know full well that the older machines will still be able to run their operating systems, but they are taking a part in the biggest scam of the whole world, which is the stock market, where their share price is dependent on how much profit they make, so they are encouraged by it to use any means that they can, in order to make as much money as they can, while not caring about if those old machines then end up in a land fill, or even in the Pacific ocean. Below is the link to the virtio drivers:

In this video I am installing Windows XP into a Qemu virtual machine and some people more might think that this is a waste of time, because XP has long been out of support, but I ended up having to do this, because I had a client who wanted to upgrade an old accounting program to a new version, but the old version would only run on XP, and they only had the database for that version, so I had to run that old version in an XP vm. XP will only run for 30 days when installed like this, but that was more than enough for me to get the job done. I also decided to install the unofficial service pack 4, which would help the XP to survive a little bit longer, against the newer exploits that have been released.
00:00:15 Download the MSMG toolkit.
00:01:20 Copying the Windows 11 installation files.
00:02:55 Time to run the MSMG script.
00:05:45 Starting to remove the Windows 11 components.
00:09:50 Removing some system components.
00:15:55 Removing some Windows applications.
00:19:40 Time to apply some tweaks.
00:26:35 Applying and saving changes to the source images.
00:27:15 Time to finally create the ISO image.
In this video I am showing how to create a Windows 11 installer, that has had most of the extra bloat ware removed, which Microsoft has decided to add for no useful reason. I am using a utility called MSMG and it was the latest stable release at the time of the recording. The removal process is quite straightforward, but you have to be careful not to remove too many things, because of course Microsoft is useless at dependency management, so you could end up removing something that is required for the setup process to complete, or that is used by the main desktop processes, which will then stop you from being able to run any programs. This version of MSMG also allows you to remove the TPM hardware check, which then allows you to run Windows 11 on a PC without one installed and even on a virtual machine, which shows how much Microsoft are like a bunch of scammers.
00:02:06 Downloading the source files for the compilation process.
00:07:15 Applying a patch for some extra architecture specific speedups.
00:08:22 Editing the config file to remove some debugging.
00:10:20 Configuring the kernel to remove the slower parts of it.
00:35:30 Updating the changelog, so that the kernel version is unique.
00:38:10 Finally it is time to run the build process.
00:39:15 The build fails, so lets find out why.
00:48:35 The build fails again, lets see what the problem is this time.
00:52:45 The build is now successful.
00:53:30 Time to update GRUB so the kernel can be selected.
00:54:35 Time to install the kernel related debs.
00:56:10 Now I am setting up the benchmark results text file.
00:56:40 Time to download the benchmark files.
00:57:24 Now it is time to run the benchmarks.
01:05:50 Now the benchmarks are finished, so it is time to boot into the compiled kernel.
01:09:20 Time to run the benchmarks again on the compiled kernel.
01:14:40 Now it is time to compare the results
In this video I am recompiling the kernel in an Ubuntu installation, to see if I can get any kind of a speedup in a couple of game demos that I will be trying out. The beginning of the video shows how to go through the recompilation process and the ending part of the video shows the results that I managed to get after all of the time spent.
After removing all of these security and debugging options, it is like I have converted a wedding cake kernel into a pancake kernel, so lets see what difference it makes
