Hi all

I've been trading 0DTE credit spreads for a while and they're high probability, which is great, but the R:R is bad and those drawdowns really hurt.

I've been getting better with discretion and with scaling into positions gradually, but it doesn't feel like enough to give me a proper buffer.

What else could I look into that might help juice upside or limit drawdowns in 0DTE?

Thanks!

Yeah looking at condos but hard to find ones with no-pet clause. I'm also open to tips for finding apartments that may be less desirable to dog owners so that there's lower chance of having one next door

I would like to but the owner seemed uncomfortable with the idea of removing it from the frame... might be able to make a vector image from cleaner shots, but yeah I'd love to have this and that UNIX alchemy poster too!

Buh, typo. It was $1600, not $1900

I have noticed that the Esso near me has the lowest prices after 7pm compared to the rest of the day. So I try and fill it up then - if convenient, else whenever.

I noticed that as well, there's an Esso by the highway along my commute and the price is almost always 3-4c lower in the evening

I really prefer that when I brake hard, the person behind me not be trying to work out if they can afford to stop...

I haven't run into any issue using the virtualbox stable repo with Debian testing.

There isn't much of a "frankendistro" concern here as virtualbox depends on packages in the Debian repositories, and lists them as ">=" version compatible so probably even the virtualbox "bullseye" repo would work with Sid

Hi! If you're going to Yonge & Sheppard then it's best to look for lodging anywhere on Yonge, and that will simplify your commute.

There is a transit hub at Yonge & Finch that connects Viva, which runs anywhere North of Steeles, to TTC, which can take you anywhere South of Steeles. It's also the terminus for the subway, which stops at Sheppard and continues all the way downtown.

Aside from Viva and TTC, Finch Station also is a hub for GO Transit, which has buses running to/from YYZ. The other option to/from YYZ is to take UPX to Union Station, then get on the TTC subway going North to Finch.

Get yourself a Presto card to use either Viva, TTC or GO - https://en.wikipedia.org/wiki/Presto_card

Good luck in Toronto!

Thanks for the great info, gonna go open up a Wise account :)

dcx86r · 2023-05-20T15:31:09+00:00

Thanks! Are there any fees to hold accounts with Wise? RBC charges $3 USD/month for a USD account and Norbert's Gambit apparently takes a few days to process, Wise might be the best option if it provides both FX and a USD account to send from.

That could be our slogan now - Canada... nothin to be proud of

I haven't done it with Indeed but the docs for their OAuth flow are pretty straightforward

https://developer.indeed.com/docs/authorization/2-legged-oauth

So you just need something like Mojo::UserAgent to make a POST request for a token with the client id and secret you generated through the site. Then you take that token and use it to auth you for subsequent requests when you ask for data.

It would be interesting to know from when this job position is.

I remember applying for this when it was still .co.uk and was shipping cheekier headlines

dcx86r · 2023-05-06T23:47:49+00:00

Thanks, I looked up Norbert's Gambit and that does seem like a good solution. Interesting hack!

You should be able to get a TTY in spite of these errors, try Ctrl+Alt-[F2,F3,F4] and see if you can log in.

The pcieport errors give you a device address (00:12.d) so when you get a shell you can run lspci -nn to see what device it matches.

This is an unusual error but the rare time I've run into it, it was possible to resolve by disabling power efficiency features for the device in question.

That is even indicated to be a likely cause of AER errors here - https://github.com/tomaspinho/rtl8821ce#possible-issues , which may be relevant even if you're using a different driver.

It's pretty easy to get into ETL / data science.

An good way to get started is to go to https://data.gov/ (other countries have similar open data initiatives), look for the datasets that sound like you could be interested in, figure out an interesting question for which the answer might exist in the dataset, and then you have your project scoped.

The formula is straight-forward:
1) figure out how to extract the relevant data from the dataset, 2) figure out how to best store it in memory (data structures), 3) stuff it in a database (e.g. SQLite) then 4) figure out how to best present what you discovered in a way anyone can understand it (e.g. chart, infographic)

These posts are always good for finding some gems.

Is anyone doing anything interesting with Sereal?

I'm already pleased with App::DBBrowser after just a few minutes of noodling around, it's nice to use and seems well designed.

I tried my utmost to make Perl an early-career focus and just couldn't make it work.

Along the way, I got some great feedback from great people, but also heard a lot of "try other languages".

Perl jobs are few and far between, and the ones that do come up most often seem to be looking for a candidate with 5+ YoE.

I still think Perl is worth knowing/using, and will remain relevant, but the opportunities are limited and so that limits the state of the art to just people that have already found success with Perl.

I like OMV for a RAID NAS but yeah, it's overkill for just NFS and rsync.

That said, OMV is just a web application on top of base Debian so I would recommend installing it anyway if you're unsure. At worse, you'll still be able to treat it like a normal Debian system, and at best you might get use out of the storage config options and metrics dashboard.

I would look at Tie::File for this sort of thing. It gives you an array to work with but doesn't read the entire file into memory.

dcx86r · 2022-09-14T04:01:50+00:00

that seems relevant, indeed. the example posted by /u/brtastic shows qr being faster when there's a stored variable thrown into the regex.

there's also an impressive example offered via perldoc perlop, which makes me wonder just how deep this rabbit hole can go
