There's a much less nefarious explanation. I'm not saying they didn't manipulate the order book feeds. I work in the regulated trading space. I've written market data decoders. One is in production inside of a bigger tra

I find it interesting that in many C++, Java and C# code bases I have read and worked on, someone cooks up an error type that they use to supplement exception handling. Exceptions are used to handle “truly exceptional” things like running o

Well, requests is a third party library. I don't like Python's standard library's HTTP APIs. I think that's a common sentiment. Similarly, you can get a solid third party its client for dotnet [1]. .NET core certainly ha

Seconded. As another commenter on this thread said, make sure you have a powerful enough machine. I work with Angular a lot. For me, Rider's killer feature is Angular integration [1]. It is far more powerful than Visual Studio's.

I imagine it is because gcc -o is a convenient way to call the linker such that it correctly links the binary and libc. Doing this manually with ld would require several (non-portable) command line arguments that would be distracting from t

What kind of an agreement did you sign with your developers? IANAL. You might be able to invoke some legal means to limit your losses. The associated-account story wasn’t an act of God. You might argue the developers should have known bette

The code has been accessible for a while now, albeit still licensed as proprietary. I went through it a few weeks ago. The Winforms code depends heavily on GDI APIs, which AFAIK are windows only and closed source

Compile it with debugging symbols and run it with gdb in tui mode. This will let you place breakpoints in source files, view back traces, find the definitions of functions, structures, macros, etc. The learning curve is a tad steep, but thi

I think the lazy and somewhat cynical answer is also the most accurate: learn the mathematics.

The chapter you're referring to is called "The Law of Line Extension". The authors call out Microsoft specifically for attempting to expand their operating system business into office software. As we now know, MS did very wel

What I’m most curious about is which business and governments had access to which Microsoft source code, circa 2005. Anyone care to enlighten me?

I think this thread has no shortage of criticisms, but too many are uninformed. The blog post doesn't mention these important things: Package management (from [0]): "Crystal libraries are packed as Shards, and distributed via Gi

Absolutely, yes. Using your CS skills to write CRUD apps is the path of least resistance to create economic value. Where I live (Johannesburg), the demand for CRUD apps is so high that no single firm or group of firms can absorb it all. You

The MS of today has massive skin in this OSS game. They've been contributing to the Linux kernel for years now [0]. They've got over 4000 repos on GitHub. Many projects are actively developed on GH. As an example, the VS code team

I used to be utterly obsessed with QS. I strongly believe that you can only manage what you measure. With that said, I've also found that quantification can have an emotional downside for individuals, especially when the stakes are low

For a gentle appetiser, see Spivak's Calculus on Manifolds. It introduces exterior algebra as a means to and end in doing computations on (embedded) manifolds. At first, the definitions seem opaque and the formalism clunky. At the end,

There is nothing funny about a web service being down? Fuck. Everyone has downtime sometimes. 100% uptime is a fairy tale. Billion dollar businesses (like Microsoft) know this and try to hit lots of nines. This error is probably stressing t

I would advise you to be as experimental as possible, and see what works for you. Each person learns things in their own way. Just picking a particular path (such as using Duolingo, as others have suggested) may work. It may not. I have fou

I agree. This would be awesome if it was written up like the Paul le Roux story on The Atavist [0]. That was gripping. I'd be so excited to read the next piece each week. I want to hear the rest of this story. [0] https://ma

Maybe because of the scale of this attack, relative to the business value Krebs provides Akamai? Shedding an attack of this magnitude (by dumping Krebs) was probably well worth the PR hit Akamai took.
