doovd··on Teaching D from Scratch: Is it a viable first language?
Well, if you learn about chars and then realise a string is a "string" of chars, then it's not so bizarre. If we're starting with ints before introducing floats, then why not start with chars before introducing strings.
doovd··on How the KGB Caught America's 'Volkswagen Spy'
Yeah I don't think the KGB were making artistic scrapbooks in their spare time. Whole article is BS
doovd··on A New Coefficient of Correlation
That's s bit unnecessarily pedantic, I think we all understand in which context we are talking about correlation.
doovd··on Ask HN: Those making $500/month on side projects in 2021 – Show and tell
Well, sure - it could certainly be the case that it's easier to scale selling trade ideas than trading them on yourself - hell there's a whole industry around it (alphacapture). I am somewhat skeptical, especially as this is marketed towards retail who have fewer instruments to guage themselves if the product their getting actually offers trade ideas with positive expected value or not.

> Same could be said about a concept of solo traders. If you are as successful as you claim why don't you run a fund?

This doesn't make sense though, running a fund is not necessarily natural progression of being a successful trader. But if one says they have a real edge that the average retail trader can monetize, then why doesn't one just take advantage of it themselves as this is effectively the lowest size of scale.

How do you answer the following inevitable questions?

If you have good trade ideas/signals, then why do you not use them yourself? I assume you do not use them yourself because it' does not make sense to share your edge (if you have one). If you do not have an edge, how can you be offering "trade ideas"?

> This dog-eat-dog "if you don't steal, you won't survive" endemic level of corruption and ubiquitous legal broken windows is IME not uncommon in shitty third-world countries

No different in most first world countries

doovd··on The Codeless CTO (2019)
What a weird response. Almost all STEM degrees require candidates to write code these days, so coding is far more accessible than underwater welding.

No J or V, Interesting those were sacrificed.

doovd··on Goldman Sachs: Here’s How Oil Prices Could Reach $90 This Winter
This is not necessarily the case, due to market spread. It's very easy to build a strategy that's consistently wrong, but by flipping the signs you will still be consistently wrong because of market spread.
doovd··on Atlassian fired me while I was taking care of my wife who is fighting cancer
Sure, easy for a bystander to make this assessment.
doovd··on NP Complete 3rd Grade Math Problems (2018)
add them all and then one on top.
doovd··on Brazil prisoners reading books to shorten their sentences (2020)
On balance of probability, how likely do you think that the their was referring to the prisoners rather than the books? > 50% presumably?
doovd··on American parents are sending their kids to 'Russian math' (2017)
Everyone understands that Russian math means Russian approach to math. And American approach does not result in general population knowing enough math. And this is why American math is lagging behind.
doovd··on AI tools have been built to catch Covid, but none of them helped
The vaccine doesn't stop you from getting covid. It reduces the effects so you're less likely to need hospitalization. So saying x% of people with covid are vaccinated doesn't mean much. There's some education for you.
doovd··on BLAKE3 1.0
How does it compare against xxhash?

Just keep changing the design on a 0.25s timer and you will satisfy the objective without fancy image processing :p

With climate change etc there probably won't be future archaeologists so :shrug:

I would not blame the problems here, but rather the lack of support.
doovd··on Show HN: A simple lazy Python calculation engine, with spreadsheet demo
This is a core principle in a lot of the dependency-graph-based frameworks seen in banks (secdb, Athena, quartz) etc. Inspired by those?
doovd··on Young Goldman Sachs bankers ask for 80-hour week cap
40 hours is excessive? From a philosophical standpoint, yes, but from the way things are in the world that's totally normal lol
doovd··on Pipe – Instant access to your annual cash flow
Meh, stock market is mostly a casino for the retail investor. If you told the bank you want a loan to pop in the stock market they'd reject you rightly so :-)
doovd··on Pipe – Instant access to your annual cash flow
> You could invest that cash flow up front. 2020 was a very profitable year in the stock market

Yes, investing borrowed money is an excellent idea. /s
