No, it happens with a proper RAID controller also, but is now fixed as I mentioned separately.

I’ve run XFS at scale and I’ve seen exactly this behaviour (files open for writing becoming truncated after power loss). However it was definitively fixed in a kernel update about 5-10 years ago. I haven’t seen it since.

It's not going to be a popular opinion due to the 10x difference in price, but I think the Rohde & Schwarz RTB2004 is one of the best hobbyist class scopes you can get (in terms of bang/buck).

No it has its own certificate system, it’s not TLS and it’s not even X.509.

That was 6 years ago and it was indeed tough back then, we were rewriting a huge trading system from Java -> C++ while trying to keep our edge. However, we succeeded and things have changed considerably since. We also have a dev working

Or you could lose nearly everything if it goes sour, I think it’s important to point that out. That’s basically equivalent to betting on options (but wrapped up in a way that looks simple). Always remember XIV.

We absolutely have this in the UK. The IOPC are the body who people can complain to about police conduct and would investigate. I presume most normal countries have such a thing. I believe any death is automatically referred for review, eve

That’s certainly true, a correctly predicted branch costs little more than a nop or unconditional jmp. Code doesn’t have to be branch free, just branch in a predictable way. Statically branch free code is great when you have things that are

I have a Kyocera color laser, no nonsense, it’s a great printer and works fine out of the box with both Linux and iDevices.

Rust becomes extremely painful as soon as you want to push the boundary. If you need to ensure you fit a struct into a cacheline, or you need to ensure an object is reused. All of these things can be done, even things like recycled intrusiv

a) Yes I run technology at a more serious HFT firm than Jane Street. b) Jane Street also use FPGAs, so you cannot exactly say they just use ocaml, it’s more nuanced than that, they are using a mixture of technologies. I think they made a ve

Try doing (serious) high frequency trading in rust, then come back to me.

by jleahy 4y ago
Unfortunately high frequency trading is an area where C++ is normally the right choice, even for a new project.

The word refers to the book of revelation, which describes war followed by famine and death. I would not say the word is being misused.

Energy. If you fire a missile to your rear then it needs to first accelerate to your original speed just to be staying still, only then can it accelerate towards the target. An AIM-9X can do this, but the kill probability drops rapidly as y

As an aside, I find a little macro that expands to asm(“int3”) is useful for this.

I guess it’s similar to comparing a $100,000 sports car to a $100 bicycle. The bicycle is a lot better than walking, but surprisingly a 1000x price difference is considered reasonable even when both products carry out the same superficial f
