... really matter are algorithmic complexity ... This is not entirely true either... Measure. There are many cases where the optimiser will vectorise a certian algorithm but not another... In many cases On^2 vectorised may be significantly

In my mind this is breaking down the problem into a relevant data structure and algorithms that operate on that data structure. If for instance you used a tree but were constantly looking up an index in the tree you likely needed a flat arr

Not something I've looked deeply in to but would it not make sense to just have a single instance of these SaaS products across your entire range of products? If you are seperating them for accounting reasons, maybe chat to an actual a

Likewise this is getting easier with the auto keyword now being sugar for templates when used in function arguments and return values

Not to be oblivious but what is the attack vector here versus attacking the router on the other end of the cable which has known vulnerabilities? How much L3+ logic is in the NIC? Pretty sure by the time a packet hits the NIC it is encrypte

> Bugs tend to disappear on me when I change the optimiser flags or run the thing under gdb though A lot of that shouts UB or compiler bug to me. I don't get this in my code unless there is some UB I missed. Unfortunately there are

You clearly have no idea how complex routing is if that is your take on this.

Yeah goroutines are a pretty high level abstraction but they are definitely closer in concept to green threads than to coroutines. You can run a C++ coroutine on a seperate thread but you effectively need to build all the task handling logi
549.
by jpc0 3y ago
Except goroutines will absolutely spawn a thread which a coroutine by definition wont. Goroutines are parallel, coroutine are concurrent. Those are not the same thing. Coroutines co-operatively yeild to other coroutines. Parallel constructs
550.
by jpc0 3y ago
I mean goroutines are not exactly coroutines nor are they threads they are somewhere in between. And its pretty easy to use the same workflow as goroutines in C++ using std::thread and a concurrent queue implementation, tbb has a decent one

Sounds like a story I've heard about a conveyer belt and a large fan. I like simple solutions to simple problems

To give some feedback. I tried your prompt and the above approach and it took me about 45 minutes of putsing around to get a result I am happy to begin iteration on. Effectively: I have an 80bit byte array representing a timestamp struct co

Are you happy with the C code generated there? I'm not sure there isn't a buffer overflow in the vector_decode code he showed there, likewise I don't see any error checks on the code and I am not familiar with the sqlite api

I will definitely try this out when I have time later in the day. There is some code I would really prefer not to write that is a decent test case for this and won't expose company code to GPT. Will give feedback when I am done. Maybe

by jpc0 3y ago
Could you maybe give me an example of what is concidered an optimal use of LLMs. Maybe a prompt to GPT
557.
by jpc0 3y ago
I was curious and yes I was mistaken.

by jpc0 3y ago
My guess is that this was generated using GPT4? Free GPT I get https://chat.openai.com/share/f533429d-63ca-4505-8dc8-b8d2e7... which has exactly the same problem as my previous example and doesn't consider the str

I did exactly that and found it lackluster for the domain I asked it for. And most use I've seen on it realistically a good LSP covers. Or to put it a other way. It's no good at writing algorithms or data structures ( or at least

Is it common for you to write the header file to say a BST and the compiler didn't rightfully throw an error? That's what you are asking the LLM to do, you are generating code not searching for an error condition. The parent comme

I think from an exposure point of view, I'm less likely to worry about the software side of my physical security being exploited that the actual hardware side. None of the points you make are relevant since I have yet to see any softwa

I'm not for or against in this case. I'm anti what Redis the company is doing but I don't give a crap otherwise. Are we really counting contribution based on LoC? Haven't we over the decades decided that isn't valid

Reasonably sure neither of those would be copyright infringements in any case. Drawings of apples cannot be copyrighted, copyright requires at least some form of originality... And this is the one that might differ based on jurisdiction but

For some things there is a lot of nuance lost in just writing. The unknowm unknowns. There has been a lot of times where I am showing someone new to my field something and they stop me before I get to what I thought was the "educationa

I figured that but agree with you. I generally wouldn't use that meaning but it's not like I'm going to fight about it being used.

No. I think users feel the other options are better due to familiarity. I generly find modern interfaces clunky and really inefficient to use and this iescoming from a younger person who grew up in win 98+. After I actually spent some time
