// float->sRGB8 conversions - two variants.

// I hereby place this code in the public domain.

// Both variants come with absolute error bounds and a reversibility and monotonicity
// guarantee (see test driver code below). They should pass D3D10 conformance testing
// (not that you can verify this, but still). They are verified against a clean reference
// implementation provided below, and the test driver checks all floats exhaustively.

Twitter Web Client Inline Image Removal

If you're a heavy user of the Twitter web client like me then you'll find the new inline preview feature extremely intrusive as it breaks up the timeline too much. If I wanted to use facebook or linkedin then I'd be using facebook or linkedin. Having said that, cards in Twitter are great and the ability to preview media before jumping off site is really cool - but it should be my choice, not have everything foisted on my timeline.

That the mobile client allows for this with a setting is even more annoying.

So here's the fix. This only works in Chrome but I'm sure an enterprising person could do something similar for Safari and Firefox using the same CSS. Pull requests to update instructions for other browsers are of course very welcome.

  ZigZag-Encoding

  Maps negative values to positive values while going back and

  (i >> bitlength-1) ^ (i << 1)

  with "i" being the number to be encoded, "^" being
  XOR-operation and ">>" would be arithemtic shifting-operation

Some links from twitter on the topic of parsing PSD files (haven't looked into them in details). PSD include a flattened rasterized image so this is easy to load if that's the only thing you need. Most software / librairies have support for extracting this flattened data (e.g. stb_image.h does).

However if you want access to individual layers, render non-rasterized layers, emulate every photoshop features, extract or apply effects with more granularity, more code is needed. May range from easy to lots-of-work depending on what exactly you need.

As far as I know there isn't a trivial stb-like ready-to-use C++ library to do that sort of things. Posting all links here. Some are probably bloated or hard to use into your project, some lacking features.

TODO: Actually look into the pros/cons of all those.

Hello software developers,

Please check your code to ensure you're not making one of the following mistakes related to cryptography.

I. General Mistakes

• Writing your own home-grown cryptography primitives (For example: Mifare Classic)
  • Exception: For the sake of learning, but don't deploy it in production.
• Using a fast hash function (e.g. MD5, SHA256) for storing passwords. Use bcrypt instead.
• Not using a cryptographically secure random number generator

Orthodox C++

What is Orthodox C++?

Orthodox C++ (sometimes referred as C+) is minimal subset of C++ that improves C, but avoids all unnecessary things from so called Modern C++. It's exactly opposite of what Modern C++ suppose to be.

Why not Modern C++?

Q. Bungie says that there will be no more host migrations, ever, in Destiny 2. Is that right?

A. Yes, it's true that that's what they've said. I'm not sure that I believe it, however. I certainly believe that what Bungie said will be true for PvP matches and for raids. For both of these cases, the console-hosted Physics Hosts of D1 did not always prove reliable-enough for a seamless experience.

On the other hand, the console-hosted Physics Hosts, in my experience, worked flawlessly in almost all other situations. Why fix something that's not broken? While at the same time spinning up expensive servers for no good reason?

Consider too the situation where you are playing the story campaign by yourself in an instanced Bubble. You don't need a remote Physics Host for this. Clearly, the entire game (except for the Mission Host) can run on your console. Why spin up a Physics Host in the cloud for solo play?

So let's assume for the moment, that when playing missions solo, there is no Physics Host,
