Scientists finally photograph a black hole

Photo of Black Hole

Photo of Black Hole

It’s weird and a too simplistic. It looks like a solar eclipse. Maybe that’s how a black hole is supposed to look like, the inverse of the sun, the inverse of the giver of light.

How To Read Attacker’s Face In Fight

Here are some sketches I’ve done to show you the faces of attackers might have during a life or death confrontation. I’m not an expert, but it might help some.

Read Faces of Attacker in Fight



1. The attacker is just puffing up his chest, showboating. If the attacker is armed, he might even fire some “warning” shots to show how tough and bad-ass he is. He wants you to think he means business. In actuality, he doesn’t want to hurt anyone. An attacker with the intent to kill would kill someone without hesitation without any of this macho theatre. Of course, I’m not an expert. Don’t go putting yourself in front of a bullet’s path.

2. The attacker is enraged, possibly preparing for actual fight or flight mode. A lot of fear at this stage. May even be the expression during the actual attack or fight.

3. The attacker has been defeated or realize he is mortally wounded. There may be shame in his expression.

If you manage to stop an attacker and for sure know he’s got a defeated expression, no. 3 above, on his face, then you can confidently move along. But an attacker isn’t completely subdued until he’s gone blue and stopped breathing or bled out. Humans can survive much physical trauma actually. Use your best judgment. In most cases, you want to avoid any fight completely.

A. If the attacker is concealing their eyes, it’s probably because they are a trained killer, or understand that their eyes give away their emotions. You might notice soldiers who wear shades to conceal their intent so their enemies or targets can’t “read” them. But sometimes you can tell by their exposed face like the mouth, if the attacker is frowning or screaming. The point being, you want to avoid people who have a gun or knife on you but also has shades on. It might mean they are dangerous people because they’re in this fight or flight situation all the time and know about how to read people, the psychology of combat. Cops are dangerous like this too.

B. If an attacker has a cold, focused, zoned-out look, it means they are willing to kill or have killed before. You should never face off with people like this. There’s a world of difference between a gangster who looks like Face #1 above and Face B. Granted, you don’t want to interact with any attacker who has the drop on you, but the point is, if you can read the attacker correctly, then you can react correctly and possibly make it out safe and alive.


Most attackers are in Face #1 or #2 and are only bluffing. They’re out to scare you only, rob you, intimidate you, and don’t intend on shooting you or killing you. However, if the attacker physically “hurts” you with the intention of saying it’s a warning, it means they are actually working themselves up to killing you, so they are an immediate danger. For example, if an attacker shoots you in the leg or cuts you or pistol whips you and say they don’t intend on killing you, that’s a lie because they’ve just caused you physical harm. They’re testing you to see if you’re willing to let them kill you, see your reaction. But I’m not an expert. This is just my personal experience. You can never predict how an attacker reacts. But it doesn’t hurt to know how to read someone’s face during a fight. It’s about survival. I’m still alive.

Green Lantern Corps: Lethal Weapon in Space

My sampling of what it could be:

Earth’s orbit

John Stewart and Hal Jordan are cruising along in a flashy vintage space speeder. Stewart is treating Jordan to lunch at a new satellite diner receiving rave reviews, just got a new shipment of cryogenic fresh food from “mother rock”. Somekind of newly genetically hybridized squid-pig.

Stewart: I hear ISS-F41 got a new shipment of goodies from mother rock. Somekind of new meat hybrid, squid-pig, or squid-cow, I think. Been looking to try it. What about you, Hal?

Jordan: Uck! What are they doing down there on mother rock? What happened to good ol’ hybrid land animals? The ida of mixing sea and land creatures together makes my stomach churn!

Stewart: Really? Remember that mystery meat we ate last week? The one you seemingly howled at the moon over?

Jordan: Yeah, what about it? It was cow-pig, right? Quite delicious.

Stewart: Haha. That was otter-jellyfish.

Jordan: Nah. I know my meats. It was cow-pig.

Stewart: ISS-F32 only gets shipments from the Pacific Coast. They don’t specialize in land hybrids. Ya sure?

Jordan silent. Then humiliated.

Jordan: God damnit. The servers on ISS-F32 were Asian!

Stewart and Jordan burst out in laughter.

Stewart and Jordan gracefully dock their vintage space speeder outside ISS-F41, a satellite diner that just opened. It used to be an international armory, but due to administrative corruption and becoming a hub for illegal drug smuggling, ISS-F41 was eventually shut down, bought out by the United Nations Space Reform Coalition, and converted into an international food vendor.

Stewart and Jordan inside ISS-F41, surrounded by other astronauts, servicemen, space lawmen, etc.

Stewart ordered the squid-pig, which came in a heated transparent pouch, looking like a pink human fetus lab experiment. But Stewart was smacking his lips with glee.

Jordan ordered the cow-pig, his favorite. He also enjoyed the green kale and gasoline smoothies. All the foods came in translucent pouches, looking like diarrhea or filled douchebags. But all around the space diner, the patrons were slurping it up, licking their fingers, wiping their greasy chins. Nothing unusual about the norm.

Jordan: Say, partner, did you hear about this new program they got building up over there in sector GL-88?

Stewart: No. I would know.

Jordan: No? It looks interesting. It’s called Green Lancers? Green Landers? Green something.

Stewart: Green Lanterns Corp.

Jordan: Green Lanterns?

Stewart: Green. Lanterns. Corp.

Jordan: But I thought you didn’t know anything about it. Haha.

Stewart: It’s a top secret initiative to recruit average space cops like us to fight an impending alien invasion.

Jordan not sure if Stewart is joking.

Stewart continues to slurp his squid-pig up.

Jordan: Hahaha!

Stewart gives Jordan serious look.

Jordan: Yikes. Are you serious? John, you kidding, right?

Stewart: Haha! Yeah, it’s a joke, man!

Jordan: Jeez. The thing with you former military top brass is you keep too many secrets! Just don’t know when you’re telling the truth or telling a lie that is actually the truth.

Stewart: And you former jet pilots need to know the difference. The universe is never black and white. It wasn’t even but 50 years ago that people were still living on mother rock. We would be out of work or chasing down criminals by foot!

Jordan: What better way to get exercise, though. I recall the training. I spent a few years on mother rock. It’s better to train as a pilot on mother rock because it just looks damn better. If you’re training to pilot spacecraft up here, all you see is black void. There ain’t no amount of VR sim environments that can replicate mother rock’s natural beauty!

Stewart: I was a land commander, way back when, well before you were even born. We only ever traversed sandy plains, dirt, rocks, mountains of dirt and rock.

Jordan: No kidding? Mother rock was still barren even back then?

Stewart: Haha!

A creepy patron is eavesdropping on Stewart and Jordan’s conversation.

Patron: Hello, officers. I hear ya talkin about The Green Lantern Corps?

Stewart: Maybe. What do you know?

The creepy patron holds his fist out in front of him, showing the two space cops the beautiful sparkling emerald ring on his finger.

Stewart reacts weirdly, as though he recognizes it. But then downplays it.

Stewart: Yeah, what’s it mean?

Jordan: It’s a Super Bowl ring, boss? Hahah!

Patron: Hal Jordan, your partner here, Mr. John Stewart, can fill you in on the details. Ask him what it’s like to fly. To really fly?

Jordan: Hey! How do you know our names?! How do you know my name?!!

Patron creepily smiles and walks away.

Jordan gets up to chase the creepy patron, but Stewart reaches out and grabs him, pulls him back into his seat.

Stewart: Listen, Hal…

Jordan: Man, that guy gives me the creeps, John. What’s he talking about? Do you know him?

Stewart: Hal, I think it’s time to tell you the truth… Ask me, Hal…

Jordan: What?

Stewart: Ask me. Ask me what it’s like to fly.

Jordan: I don’t get it. You aren’t a pilot.

Stewart: No, Hal. Ask me what it’s like to fly… to really fly.

Jordan: Haha. You mean fly a plane? Or like fly-fly?

Stewart gives ominous look.

Jordan: No… can’t be.

Stewart: Boy, if you want to know, you’d better ask now. Ask me what it’s like to really fly.

Jordan: Shit. John. What’s it like to really fly?

Stewart gives coy smile. He reaches into his coat pocket and pulls out something. Slides it on the table.

It’s a Green Lantern ring and it starts glowing.

Jordan: I don’t get it. It’s just a glowing ring.

Stewart: Hal, you have a lot to learn.

Stewart raises his hand and slips the ring on. He clenches his fist and a burst of green light and energy fills the space diner. Everything is covered in green tint and stopped in motion.

Jordan: Whoa! What the hell?!!

Stewart has now transformed into a pulsating green energy, like a green spectre, but he still has a humanoid form.

Jordan: Arrrhhhh!!! John! John! What’s happening?! Man, you’re a ghost! What?!!

Stewart: Calm down, Hal. I’m still John Stewart. But I’m also a Green Lantern. Welcome to the Green Lantern Corps, rookie.

Jordan: How?

Stewart manifests another Green Lantern ring by pulling it out from his own ring on his finger. He hands it to Jordan.

Stewart: Put it on. You are a Green Lantern now.

Jordan: Uh…

Stewart: Put the ring on. Then ask me what it’s like to really fly.

Jordan: Fine.

Jordan puts on the ring and…

Now Stewart and Jordan are floating out in the middle of black space, both in spectral Green Lantern form.

Jordan screaming in horror.

Jordan: What’s going on here, John!!! How is this happening?!!

Stewart: Haha! Notice something strange?

Jordan: I dunno, man! We’re green ghosts floating in the middle of space!

Stewart: Floating? Or flying?

Jordan: Holy shit. We’re flying! But how?

Stewart: The universe has all your answers, Green Lantern. You know what it’s like to be tasered?

Jordan: Of course. It’s one of the first things cadets experience during training.

Stewart: Do you feel that similar sensation now?

Jordan: Yeah. I think so.

Stewart: That is the living life force of the universe. That is how we “fly”. We are not in our humanly forms right now. This is our Green Lantern spectral form. You can lean on universe and it’ll lean right back. I guess you can say it lifts and carries you where ever you want to go. Go ahead, give it a try.

Jordan: How?

Stewart: It’s like swimming and walking at the same time.

Jordan: OK…

Stewart demonstrates how to fly as a Green Lantern. Jordan watches in awe.

Jordan floats in space awkwardly. He comically tries to move, but starts spinning out of control in place.

Stewart starts laughing at him.

The Jordan tries to stop himself by spreading out his limbs. Instead of stopping, Jordan balloons up as huge green ball of energy and explodes.

Stewart is laughing harder.

Stewart: Hal, you gotta learn to control your energy. Otherwise the universe will reclaim you.

Jordan (voice only): Say what? Where am I? Where’s my body?

Stewart: Concentrate hard and recollect your energy into one form, Green Lantern.

Jordan: How? I can’t!

Stewart: It would feel as overwhelming as getting tased by a million volts of electricity, like you are containing the energy of the sun.

How To Play MIDI music files on Windows 10 with VLC Media Player

If you missed being able to play MIDI music files on Windows by default, now you can play those tunes you remember again with VLC Media Player version 3.0+. Apparently, there was a security flaw in FluidSynth for VLC version 2.0.x, so MIDI support was dropped until version 3.0+. So download the latest version 3.0.3 (as of this post) along with the free soundfont file VLC recommends, configure Fluidsynth to point to the soundfont through VLC settings, and you’ll be listening to those old video game tunes in no time!

Follow the instructions here:

The Real Shape Of The Globe

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:”

By Chongchen Saelee

UPDATE: April 27, 2018 – It seems all I had to do was click the “Reset to Defaults” button at the bottom of the AutoPlay window, which grays out all the options to “Choose a Default” and no more problem pop-ups now when I eject a Blu-ray from PowerDVD. Of course, this is only a Windows 7 problem.

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!
