But arr != &arr even though they have the same value. #8 applies to arr (P), but in the post OP is using &arr which is a ptr to array[x] and doesn't apply to it.

by halayli 10y ago
this is undefined behavior. &arr + 1 can overflow. There's no guarantee &arr isn't near memory end boundary. &arr + 1 is converted at compile time to rbp - X where X is an integer determined by the compiler similarly t

you can trust their skills and ability, but trusting their intentions shouldn't necessarily follow.

One benefit of testing is that it can highlight whether your abstractions make sense. If you need to pull in the world to test a small module then probably your dependencies are not right and what you thought was a unit turns out to be more

You want me to trust my life with a source code that uses zmq? no thanks.

Why not use clang's PCH (precompiled headers) feature? http://clang.llvm.org/docs/UsersManual.html#precompiled-head...

It takes time (few months) and plenty of iterations to create the mental map and learn the proper patterns. I suggest to create a simple app and iterate/refactor until you feel comfortable that you got it. Boilerplates are good but t

What evidence do they have that it's a state sponsored attack?

by halayli 10y ago
This increases your attack surface area. Any breach to one of those machines and the attacker can start doing mitm attacks. It also limits auto scalability assuming newly provisioned machines require manual approval of priv key distribution

Wouldn't this require private keys to be sprinkled on all machines running it to inspect the traffic?

It doesn't need a lot of thinking that I was referring to programming languages.

You're in denial. Javascript is everywhere nowadays. It has become the English of languages. It's not my favorite language but it has improved extensively. No one wants to maintain a web app, mobile app, and desktop app separately

Your page can be very fast and uses minimal resources and is hosted in a good place. But you always gotta watch out for proximity to user, time to first byte and dns resolution time. Perceived speed is highly affected by those. It took 2 se

I feel you're trying to defend go without much objectivity. Such performance gap needs to be addressed properly instead of saying it's pretty good already. It doesn't sound right if go takes 5 hours to finish csv parsing job

OO paradigms are not magical and they have a learning curve. They can look simple and obvious but knowing how to abstract your problems using these techniques is not simple and it's what differentiates a good programmer from a bad one.

What about mental fatigue? The more you workout your brain the more it needs to rest. How would you like your brain to tell you that it needs to rest other than feeling fatigue? I find myself consistently productive over long spans without

memcpy is outside the territory of C++. it doesn't fall under the language specification. it's as simple as that. If they go this route what stops them from defining assumptions to system calls?
379.
by halayli 10y ago
but memcpy outside the C++ scope is what I meant. The C++ committee cannot do much about memcpy but they can introduce a new memcpy with a different name that has better ub support.
380.
by halayli 10y ago
memcpy behavior is not part of C++ standard. The C++ standard is only concerned with formally defining the ability to use it and the header name to include.

there's no license for kqueue's interface or netgraph, and many other great interfaces. but they decide to create square wheels and not leverage from errors that others have made before them.

Looking at dtrace, fishwork, zfs and Solaris (imo was the best OS technologically speaking) it's interesting to see how strong and innovative its engineering team was while the business was just going down. How did that happen? How can

This article is coming from a frustrated developer and lacks any scientific evidence. The frustration (understandably) is coming from the overwhelming complex new features and patterns that barely a compiler can understand. C++11 onward rev

you can do x = malloc(sizeof x + <variable_length)) x->zero_array points to the variable_length. The advantage is that you get contiguous memory access and do a single malloc. As opposed to: x = malloc(sizeof x) x->ptr = malloc(&

I bet a package manager will follow it. redis install moduleX and then we'll have lib and target dependencies.

with the risk of sounding cynical here, but it feels this is a solution from people that aren't familiar with what the problem is about, ending up in optimizing the wrong areas. Few observations here: * using udp means you don't c

Goroutines use segmented stacks that allows them to grow dynamically as needed. so 4k goroutines != 4gb of ram. They currently start at 8k and grow as needed but copies are incurred to keep it contiguous. In lthread I preallocate fixed size
