I'm not a D expert, but I think the raptor_uri_copy is called in dup() method of URIWithoutFinalize/URI, which is essentially the full_copy() method. The code says only URIWithoutFinalize() is shallow-copyable, and URIWithFinalize

That kind of mitigation just makes me one step away from Rust - system programming languages should stick to the platform behavior, otherwise it's just another Python. Moreover this change is not documented anywhere else. Have a look a

Personal option: Separating leak from UAF and claim the former is more acceptable should not be the case, because leak applies to more than memory, and leaky fds can also create security holes like [0] [0]: https://labs.portculli

Have to say that nothing can make your program automatically safe (defined by common sense, not "memory leaks are also memory safe"[0]) without any effort, and the trend to claim some languages are inherently "safe" whil

I hope the split dwarf problem was fixed (haven't checked it out), which would make linking way more faster.

That's true. Carrier Grade NAT now records NAT log and sends them to tracking servers.

As a C developer I have to say there exists no idiomatic makefile - configuring header file dependencies with -MMD/auto rebuild targets affected by FLAGS change already makes your Makefile look like magic. As the project grows, eventua

To be fair, it is not tough at all for a "high-skilled" foreigner to work at China by getting a Z-visa - I guess most employees at Bay Area fall into this category.

Just an opinion: Rust and C++ are going on different paths and selecting different subset of features. Rust generally lies in higher layer, while when it comes to tough situations like ABI compatibility, a machine that CHAR_SIZE does not eq

The story sounds quite familiar in both data scientist and system programming parts - in past years system programming(especially embedded system) is highly undervalued. As I know some of my friends doubled their package simply by switching

I have to say that most "Rust is fast" articles I read stop at comparing microbenchmarks written with not much care on performance. I really want to see some comparisons in highly-optimized cases like linear algebra library (Eigen

It's more like Chrome/Google play framework in China (and they are all blocked). Not surprising if you compare WeChat to a combination of GPay, GGame, GStore, etc.

It's for app-lockin. Most people will not uninstall an app after installation. Moreover many new Internet users in China cannot even remember a password that's secure enough.

Nice examples and graphs. What really confuses me is the definition of "low-latency" nowadays. The meaning suffers a slippery slope in recent years. It used to refer to a scale of microseconds at HFT shops, then it came to web req

This should be a library function that will not be exposed directly to most developers, who only need to know for_each(Range, fun) which is pretty straightforward.

You cannot understand every assembly generated by modern compilers either. Both C & C++ provide no guarantee for any of these. Since ranges is basically a pair of begin/end iterator, I think it will be almost identical to it.
