I think my current password are used for last ten years and somehow I still didn't change it and relay on the 2FA to protect my account

What's more I only have one yubikey and doesn't have a backup for those 2FA identities.

Well... That may not be a good practice.

Now I achieved 11+ fps with GLSL shaders to draw a colored circle. This circle has been sliced into 30e5 segments and CPU only give a index of each segment, then shader computes each vertex's coordinate and give them color.

I think that is a nice try for a OpenGL beginner.

Encountered a mind-blowing problem with OpenGL.

When I finally drew a circle using LWJGL with OpenGL, I tried moving my code from glBegin/glEnd calls to VBOs, and today I tried to make my code using shaders. And problem is here.

I draw a circle by slicing it into some segments and calculate the coordinates of points on the edge, then I can use GL_TRIANGLE_FAN or GL_LINE_LOOP to draw a circle. I randomly choose a color by assigning red equals cos(theta), where the i th theta is 2 * pi * i divided by total segments.

If I draw the circle using GL_LINE_LOOP, the color on the edge is correct, where only theta in mines pi to pi is positive number, thus given the red color, which should be the right hand side of the circle. Picture 1 is a compare that on the left I used GL_COLOR_ARRAY client state to draw color, on the right side I use shader but calculated cos before fragment shader(both in CPU part and vertex shader, they are same in result). In picture 2, I calculate cos value in the fragment shader by the theta passed by vertex shader. And it shows on the right of the picture, which is pretty odd.

I knew there other stages between vertex shader and fragment shader, but how they effect those color or theta value? Also on the left side of picture, color gradient given by fixed pipeline also seems a little bit weird.

BTW I have no ideas about where to find those documents. LWJGL doesn't have a detailed document on OpenGL(which I guess they of course not have one), and on the OpenGL side, the documents are just overwhelmed me...

Medicine always amazing

As soon as I take the first pill, my nose feels much better.

have a cold with pretty strong symptoms
95% percent sure it's not covid 19

I feel so fucked up by just having this little flu (I guess), I lost my towel and struggled to finish my passages. I felt like I'm broken and I knew that shouldn't be that hard, but I can't finish that properly. Anyway at least I finished that and found my towel.
Now I somehow understand the feeling who has severe disease, feeling of frustration. A friend of mine has struggled with cancer for several years and it's really unbearable.

Symptoms from flu and the friend trying to fighting the cancer, both make me feel sad.

It's 11:30pm in UTC+8,
I think I'd better go to bed now.

Everybody goodnight 😴

太强了，人均BiLSTM CRF，我记得去年搞这个，因为dl4j没有CRF层，于是用了一层attention代替，结果效果极差

可能还是语料太少（指用整个中文维基作为语料）吧（逃

I rerun the code this morning and it didn't crash.

I didn't change anything and it just magically runs. But still I can't see anything on that window. My OpenGL codes probably still broken.

I want to draw a circle using lwjgl (with OpenGL as underlying library) as a hello world program

...and the jvm just keep crashing

Fine.

Anything related to C++ is hard.

This is why we can't have nice things

New configuration

Dual screen works fine for me.

Another use of dual screen is laptop for gaming guides, monitor for switch XD

I'm confused with squid and octopus, especially as a Chinese 🤔

Fine.

And another point that I HATE HP's customer support is that they charge me 1400CNY(~ 200 less USD) for a M.2 Sata interface SSD, I thought it was NVME with that price, but after 6 month later I find out that is Just a SATA SSD.

As the replacement of my old HP OMEN w205tx, 2.09KG is really good for carrying around in university, while my old HP laptop is 3.35KG.

The only downside of razer blade is the surface. The surface is smooooooooooth but it's really easy to get dirty. Even a slight touch with a fresh washed finger can make it dirty. It's going to make me mad just in my first couple hours with it.

But with 8c16t 10850H and RTX 3070 GPU with so many CUDA cores? It blows away of my old one, with 7700HQ and GTX 1060 mobile. Also the 4~6 hours battery is much better than the old 2 hours less battery life.

Also I heard about bad battery issue on razer blade 15, but my my old hp one encountered same issue too, and it cost my 1300CNY with official custom support, while I can just spend 500CNY to purchase a battery and replace with my self.

New blade 15 arrived

expecting service as daily drive for next 5 years
