--- NVIDIA announces PhysX SDK 4.0, open-sources 3.4 under modified BSD license ---

NVIDIA has announced a new version, 4.0, of PhysX, their physics simulation engine.
Its new features include:

- A "Temporal Gauss-Seidel Solver (TGS)", an algorithm used in this SDK to make things such as robots, character arms, etc. more robust to move around. NVIDIA demonstrates this in the video by making their old version of PhysX, 3.4, seem like an unpredictable mess, the robot demonstrating that version smashing a game of chess.
- New filtering rules for supposedly easier scalability in scenes containing lots of both moving and static objects.
- Faster queries in scenes with actors that have a lot of shapes attached to them, improving performance.
- PhysX can now be more easily used with Cmake-based projects.

In essence, better control over scenes and actors as well as performance improvements are what's new.

Furthermore, NVIDIA has released PhysX version 3.4 under the 3-Clause-BSD-license, except for game console platforms.
As NVIDIA will release the new version on December 20th, it will also be released under the same modified BSD license as PhysX 3.4 is now.

What are your thoughts on NVIDIA making a big move towards the open-source community by releasing PhysX under the BSD license? Feel free to let us know in the comments!

Hi, rant. I've just finished one of my hobby work. :D
Just another O'RLY book cover generator, written in Golang/Vue, supporting more glyph like CJK.

You may try it on https://rly.nanmu.me/

Source code is available via MIT license on https://github.com/nanmu42/orly

Cheers. :)

Lately, I see a lot of rants/comments/jokes about WinRAR and its eternal trial (algorithm, is that you?). Here's a nice video explaining why WinRAR chose it as its business model and how it works: https://youtu.be/fTgZRVVr3_Y

Spoiler alert: WinRAR is brilliant.
But use 7-zip or be a command line ninja.

This time I want to share with you something I am really proud of. As I love sailing (I've been sailing for a long time before I even had my driving license - for over a 20 years now), and I love old, classic, wooden yachts - this is the result of couple of years of work. My own oldtimer Jollenkreuzer 15er:

This is almost the same Jollenkreuzer that Albert Einstein received as a gift (despite the fact that he didn't know how to sail). Emir was built in 1953 and the renovation took over 5 years and it wouldn't be possible if not for my father.

Guys checkout my first UI widget for android here

Feel free to use the widget wherever you want, I havent yet added the license because I'm lazy but its apache 2.0 so enjoy.

Hey everyone, cozyplanes here with another quick excel prank i thought of.

It is called TEEST, and the technique behind is simple, but interesting. Recommend taking a look, and pranking with your friends.

The following is the README of TEEST (Text in Excel Every Single Time) in Github.
You can check the simple project here ( https://github.com/cozyplanes/teest )

Disclaimer: Do not use or modify neither the program or the source code to make software violating the law.

### How do I use it?

1. Head to https://github.com/cozyplanes/teest and download the latest release `EXE` file.
1. Windows may warn you with the missing signature. The file is a DEBUG file, so there isn't a publisher signature. You can proceed downloading anyway since it has been virus checked by the developer.
2. Type the message you want to display in the textbox.
3. Click `Save text` button.
5. To check the file, click `Cancel` button in the opened popup dialog.

### What happens?

When an MS Excel file (`.xlsx`) has been opened, by using TEEST, two files gets opened.

1. The original file user opened
2. Excel file named `message.txt` with the custom message you have written.

`message.txt` excel file will open every single time a person opens a excel file.

*In some older versions of Excel, the message may overlap with the user opened file.*

### Why does this happen?

When MS Excel program is executed, it is programmed to check the files in the following 2 folders.

- `C:\Program Files\Microsoft Office\Office[versionnumber]\XLSTART`
- `C:\Users\%username%\AppData\Roaming\Microsoft\Excel\XLSTART`

In normal conditions, there is no file in those folders (or the folders doesn't exist at all) but when you use TEEST and click `Save text` button, it saves `message.txt` file in the folders above. From MS Excel is executed again, it will find out there is a file in the folders above, so it will show those text files in Excel.

### Where is this technique used?

There should be a lot of software using this trick, but it is widely known for ransomwares such as `GandCrab` and `TeslaCrypt` displaying decryption methods in MS Excel by this trick.

### How can I disable it?

1. Open TEEST again.
2. Click `Save text` button and click `Cancel` in the following popup.
3. Delete `message.txt` file in the opened explorer.

I'm raging all over the place at the moment. I've just inherited possibly the worst PHP project (Codeigniter) in 10 years.

Apart from the fact that the previous developer has created 87 different header and footer files (same content, but each screen has different footer file for some reason, i.e. footer-login.php, header-login.php, footer-profile.php, header-profile.php etc.), he seems to like adding the following comment all over the place: "Released under MIT license: http://opensource.org/licenses/..." to some how protect is shitty code. I mean take a look at the below of some high quality,propriety Jquery he's written, under MIT.

!rant

So, I don't have any idea about copyright law. I've heard, that React is bad, as it has a `if you sue or in any way "compete" against us, we revoke your licence` clause.

So how bad is this? Is this really a thing, unless you either sue FB, or they try to buy you (which are both not very probable for small companies). Could someone who knows their shit give me a tl;dr summary (or feel free to debate)

What I've found so far: https://github.com/facebook/react/... which seams to be kind of ok.

This would be the patent: https://github.com/facebook/react/...
