The Real Shape of The Globe
By Chongchen Saelee

Most depictions of the globe is an oversimplification, a mapping projection made by cartographers so it is easier to read and navigate.

But the actual physical earth is not a perfect sphere. If anything was a perfect sphere, it would be the Earth’s atmoshphere. Everything else is irregular. So to map the physical land to a perfect sphere is inaccurate.

So if you were to fly a literal straight path from point-to-point, there would be no curve like how some animations depict it. You would actually travel faster and shorter distances.

How To Fix Windows 7 PowerDVD 17 Error: CL RC Engine3 Dummy Winidow: PowerDVD.exe – No Disk

How To Fix
PowerDVD 17 Error Message
CL RC Engine3 Dummy Winidow: PowerDVD.exe – No Disk
“There is no disk in the drive. Please insert a disk into drive D:”

Symptom: Occurs on some Blu-ray discs upon ejection. Sometimes might even freeze Windows or lock the BD-Rom Drive

PowerDVD 17 Error Message CL RC Engine3 Dummy Winidow: PowerDVD.exe - No Disk "There is no disk in the drive. Please insert a disk into drive D:"

PowerDVD 17 Error Message
CL RC Engine3 Dummy Winidow: PowerDVD.exe – No Disk
“There is no disk in the drive. Please insert a disk into drive D:”

Solution: Apparently, for Windows 7 anyway, there was no option during installation to prevent PowerDVD from setting the Windows Autoplay hardware associations, despite providing a file format associations page. The Windows Autoplay associations deal with hardware rather than software and seems to be automatically set by Windows (you might notice the Autoplay pop-up whenever you put in a new disc of USB with media files on it). To prevent the error from happening, you must disable Windows Autoplay for any devices that were set to call PowerDVD, in this case for the Blu-rays (or any other media).

For Windows 7:
1. Go to Control Panel > Hardware and Sound > AutoPlay
2. Under the Media pane, for every media option that lists “Play {media} using PowerDVD 17” change it to “Take no action”.
3. Click Save.

Change Windows 7 Autoplay settings to fix PowerDVD 17 error

Change Windows 7 Autoplay settings to fix PowerDVD 17 error

Now when you eject a Blu-ray disc through PowerDVD, it won’t give the error message.

If you’re still getting the error message, it might be due to something else. Good luck!

Qt 4.8.5 c++ 3D demo update!!! No OpenGL or DirectX just pure Qt

Had to revert back to Qt 4.8.5 but it works nonetheless. The video is choppy because I’m screencapturing the video as it’s running, but on my quadcore it runs at steady 60 fps. On duo-core it runs a steady 20 to 40 fps, so it really depends on your hardware, or I just need to optimize it more. But check out pure 3D in Qt and c++, no third-party dependency on OpenGL or DirectX!

How To Download m3u8 videos from Twitter

How To Download m3u8 videos from Twitter
By Chongchen Saelee

If you’re browsing websites like Twitter or Facebook, you may notice videos may not be accessible for download. Back in the day, it was quite easy because the actual video file is embedded right into the page. These days, with privacy concerns (and copyright issues), Internet videos are becoming harder to “save for offline viewing”. But with a little know-how, you could successfully save these videos for offline viewing. After all, the data has to be sent to your computer anyway.

So particularly for m3u8 file format, which is just a plain text file that includes a playlist of urls to source videos (and sometimes other playlists), what you’re looking for are ts video source urls. Of course, you have to track down the url of the m3u8 file first. In Google Chrome, there is the very helplful “inspect” tool in the Developer Tools menu. Or, if it hasn’t been obfuscated, you can right-click on the part of the webpage wear the video will render and click on “Inspect” if that option is enabled. Then you want to track down that url for the m3u8 file. Download the m3u8 file and open it with a plain text editor like Notepad. (more…)

Neuromancer (1984) By William Gibson Review

Neuromancer
Author: William Gibson
Published in 1984

Review By Chongchen Saelee

“Neuromancer” is the chosen template for modern sci-fi stories since it’s publication. It seems every modern sci-fi story from The Matrix, Ghost in the Shell, Akira, etc, all borrow heavily from Neuromancer. If not the exact storyline, they borrow the speculative Asian culture imagery. But masquerading around as a futuristic caper story, Neuromancer is actually more like a crime noir story, since main plot device involves protagonist Henry Dorsett Case’s lost love Linda Lee. It bookends the whole story, although executed kinda sloppily.

Overall plot revolves around “cowboy” or what we call these days “hacker” Henry Dorsett Case, a 24-year-old thin druggy white guy. He lives a dangerous lifestyle in a dangerous futuristic world that resembles modern Tokyo. Case makes a living hacking into computer systems and otherwise cyber espionage. He spends that money on drugs and prostitutes. Of course future drugs don’t just come in the form of chemical substances, for those with man-machine interface built into their heads, they can get high off of “microsoft” which is essentially programs that scramble their brains temporarily. Mind-blowing, right? (more…)
