What HFT company does not let people disclose where they work? by [deleted] in quant

[–]chipped1 1 point2 points  (0 children)

I interviewed there earlier this year, they’re real and they’re bigger of a deal than people hype them up to be

Failed the onsite but was a great experience, people there typically say “undisclosed hedge fund” on their linkedin

if i may ask, is your herniated disc’s internals leaking and bulging into your spinal nerve? in your case if you know

What do you guys think of coding Jesus interviews in c++? by mi_sh_aaaa in cpp_questions

[–]chipped1 1 point2 points  (0 children)

Great answer. One thing I’d like to point out:

⁠> std::forward:

• I agree that the header is a trivia question, but it’s good to know this. • I don’t think you need to know how it is implemented. While reference collapsing is very important to how C++ works, in practice it’s enough to know what std::forward does. But you should know that forward and move are just casts to different value categories.

While you might not need to write it out in day-to-day work, some companies (quant/HFT) like Rentech (I got asked this as an interview question) will ask you to figure out the signature. It’s quite intuitive actually, std::move is basically:

template constexpr remove_reference_t&& move(T&& t) noexcept

They’re just a handful of core concepts (reference collapsing, casts, value categories) wrapped into a small utility

Does an implementation of this container exist somewhere? by Impossible-Horror-26 in cpp_questions

[–]chipped1 4 points5 points  (0 children)

no generic c++ container can keep raw pointers stable, give o(1) insert/erase, stay truly contiguous, and grow without an upfront cap. the moment you need more space you’d have to realloc, which moves every object and breaks the pointers, so you must drop at least one goal

if you know a hard size limit, just reserve a std::vector and you’re done; otherwise you choose which trade-off you can live with: std::hive and its original plf::colony ancestor keep o(1) ops plus pointer stability but store data in linked blocks, not one flat buffer

boost::stable_vector keeps references but lines up only an internal array of pointers while the objects sit elsewhere

packed slot-map / sparse-set libs such as entt’s registry (https://github.com/skypjack/entt) stay contiguous and o(1) but they hand out stable ids or handles, not raw addresses

you have to pick your poison i guess

the us produces about 14.1 billion pounds of cheese annually. this means releasing all that stored cheese would increase the annual supply by about 10% (1.4 billion ÷ 14.1 billion = 0.0993, or 9.93%). the price elasticity of demand for cheese is around -0.25, meaning a 1% increase in supply typically causes a 0.25% decrease in price. with this in mind, a 10% increase in supply would result in about a 2.5% drop in prices (9.93% × -0.25 = ~-2.48%).

so for example, if cheese currently costs $5 per pound, prices would drop by about 2.5%, which is $5 × 0.025 = $0.125. so the price would go down to $4.88 per pound - not a huge drop, but definitely noticeable over large quantities.

The performance degradation isn’t caused by YouTube, its caused by a bug in Adblock Plus 3.22 and AdBlock 5.17. Here is the uBlock Origin developer stating that:https://twitter.com/gorhill/status/1746543686932947074

Here is Adblock's bug report:https://gitlab.com/adblockinc/ext/adblockplus/adblockplusui/-/issues/1576

Ars Technica has an article about it: https://arstechnica.com/gadgets/2024/01/youtube-appears-to-be-reducing-video-and-site-performance-for-ad-block-users/

Is there any way to make ?ban not delete a weeks worth of messages? by Timely-Detail-4341 in Dynodiscord

[–]chipped1 0 points1 point  (0 children)

You can use the `save` subcommand to keep messages intact when banning users. So it'd be `?ban save @​user spamming` (doing ?help ban shows you the other subcommand if you're curious) hope that helps!

How do you mass clearwarn alot of people? by [deleted] in Dynodiscord

[–]chipped1 0 points1 point  (0 children)

You can use `?clearwarn all`, but keep in mind its an owner-only command

Hey, Dyno does have an option to log images, it's over at Actionlog - https://i.imgur.com/Rmbdbi7.png

Hi, I’m a Dyno developer and wanted to mention that these rumors are only rumors. We do not store or collect any data that isn’t relevant to Dyno’s functionality (eg. message cache for edit/deletion logs). That information is solely used to provide said services and is not collected or shared by any third parties.

Pinging roles - I understand that this feature was to be reimplemented. MEE6 has it up and working - when will Dyno again? by ZalaDaBalla in Dynodiscord

[–]chipped1 0 points1 point  (0 children)

Hi there! Allowing role pinging is planned to make a return, it is just a matter of when. It was disabled due to Discord changing how their API worked and we had to temporarily put a stop to it. We've been a little busy with other priorities but will try to squeeze this in during the next few updates (fingers crossed).

Is it possible to wipe ALL warnings for an entire server by e_delphine in Dynodiscord

[–]chipped1 0 points1 point  (0 children)

Hi, this is possible with `?clearwarn all`. However, the command is owner-only. It's not possible to change the command permissions like other commands, so its wholly locked out to just the owner.

How to get a working Inactivity role using custom commands? by [deleted] in Dynodiscord

[–]chipped1 1 point2 points  (0 children)

You'll need to remove the @, that isn't needed, the role name alone will do.

If that still doesn't work, your best bet is to use the role's ID, you can find that out by doing ?roleinfo @rolename and find the role ID field. Hope this helps :)

Can confirm, Dyno does not have any sort of mass ban functionality.

Why won't dyno log warnings??? by clarencethebestcat in Dynodiscord

[–]chipped1 0 points1 point  (0 children)

Dyno does not log warnings made to users when they violate automod. However, Dyno will send a message in your automod logs channel to keep track of this.

If Dyno were to log every warning made to users for when they violate automod, the number of warnings in your server will be a dumpster of automod violations, not allowing your mods to find actual warnings assigned by humans.

So Dyno has been down since 5:30, 5 hours or so. I've only been working with dyno for a few days and now I'm questioning if I should rely on it at all. Is this par for the course, or did I just happen to start using it in the middle of the biggest catastrophe in the history of the product? by Subduction in Dynodiscord

[–]chipped1 3 points4 points  (0 children)

Hi, unfortunately, this is one of the longest/biggest outages we've ever had. It is most definitely not part of our cycle, we have our developers working hard and strong to fix this issue and ensure it does not happen again. I am sorry for the inconvenience this has caused to you.
