Someone on HN that does not use ad block? This is still so confusing for me. Why not spend 40 seconds and never see any ads more?

It is not that simple, atleast in the automotive industry _today_. Atleast here in EU.

Every component is analyzed from a cyber security perspective. Many components needs tampering protection - while others need not. This includes replacing components with malicious ones.

It is not logical at all and a stupid regulation. But it is not as simple as you can do what you want if you have physical access.

New comment by dosshell in "Solid Queue 1.6.0 now supports fiber workers"

Some context:

Fiber is a datastructure where the execution context is saved. Eg. registers (including instruction pointer) and stack etc. That is a fiber: data.

You normally use a threadpool, core pinned, to execute these fibers.

Since you jump in userspace, you more or less only have to pay for cache misses.

There are many upsides of designing a program using fibers. The major downside i see is that you can not blindly trust mutex and semaphores any longer - since the fiber can change execution thread while yielding/waiting for condition.

It is very important to note that you can not leave Ceuta without passport etc. It is not part of Schengen. This is a problem for Ceuta and Spain, and nothing more.

Think about that when you read what your politicians say about the incident. I have seen many lies and false statements the last few days.

The leaders should stand by Spain, not lie to their citizens about the situation to win votes.

Every place I worked at has a git introduction where all new employees learn about how git works internally. Takes 1h, and all junior devs stops memories random commands and actually start to understand. I highly recommend to you to poking around in the .git directory.

The git support for new employees drops basically to zero.

Drivers exclusive for Windows.

You know your old Soundblaster AWE64 Gold, with all bundled programs [0]. Or that very special Analog Video grabber card you have.

Wine is user space. This is the full OS.

[0] Ok, that maybe works in linux, but you get your point.

i investigated this yesterday and there is one cmake extension. It gives basic support to cmake. Not as neat as vscode/jetbrains/qt/vs but it works. It is depends on CMakePresets.json and has no gui etc.

you would lose 80 repos from "10000 : 1847" also in that case.

what do you mean with "The browser-based IDE (editor ...)

You use Monaco Editor for that.

What parts have you exactly built?

All I see are dependencies that are glued together with claude.

Can you clearify exactly what you have developed?

If it captures variables, it is not possible to manually declare the type. You can however hide it in an std::function. But then you probably get some overhead and some heap allocations in real life.

You put the using as class member (private) or as local in the function.

Note that: There are no economic science Nobel prize.

Only one similar named price in the name and memory of Alfred Nobel, which some how, is allowed to be part of the Nobel prize celebration.

I guess my opinion is in minority, but i don't like that another prize hijacks the Nobel prize.

I tried to reproduce it on Ivybridge (Windows VS20122) and failed (mulss and muldd) [0]. single and double precision takes the same time. I also found a behavior where the first batch of iterations takes more time regardless of precision. It is possible that this tricked me last time.

Sorry for the confusion and spreading false information.

dosshell — Mon, 22 Apr 2024 21:03:17 +0000

I agree with you. It should take the same time when thinking more about it. I remember learning this in ~2016 and I did performance test on Skylake which confirmed (Windows VS2015). I think I remember that i only tested with addsd/addss. Definitely not x87. But as always, if the result can not be reproduced... I stand corrected until then.
