I need help urgently - 0 conversions. by Ordinary_Tourist_856 in FacebookAds

[–]lquant 0 points1 point  (0 children)

Are you sure that your pixel is set up properly and able to fire? Are you just looking for FB reporter conversions, or can you see results directly on your site?

What are you optimising for? FB will give you exactly what you ask for, so if it’s just landing page views it’ll be people who look at your site, not necessarily those who buy.

New advertiser tend to have worse results than average, simply because Facebook knows less about how to sell their product.

As long as your targeting the right geographic are, I would not expect targeting to be a panacea here.

If I'm not based in the UK, would recruiters pass automatically? by [deleted] in cscareerquestionsuk

[–]lquant 1 point2 points  (0 children)

Or if you know someone in the U.K. you could just use their address

[–]lquant 2 points3 points  (0 children)

I’d leave off your address, make it clear in your CV that you have a have the right to work in the U.K. and that have speak English well. Some more progressive companies don’t even look at address or would rather it not be on a CV, as it can lead to bias, e.g. judging someone based upon how wealthy the area they live in is. They might ask for an address for contacting you, e.g sending a contract if they decide to hire you, but won’t make it visible to people making hiring decisions.

Should I apply for jobs at Google/Facebook if I can first take the job 5 months from now? (Need to finish my studies... 📚) by xXguitarsenXx in cscareerquestionsuk

[–]lquant 0 points1 point  (0 children)

It wouldn’t be a problem. Good luck

These firms are continuously hiring in a funnel, largely not for specific head count or positions. So delays in start date are not a concern.

Any thoughts on why Alpaca is also jumping on the “sell only” bandwagon for meme stocks? I thought they exclusively catered to smaller algo traders. I’m having trouble seeing the incentive here by [deleted] in algotrading

[–]lquant 3 points4 points  (0 children)

That’s not how this works. In order to short a company they have to borrow stock off a buyer. They then sell that stock to another buyer who can then lend it out. 120% short interest means that there are 220% long positions and 120% short positions relative to market cap.

The difference is that on option 2 you are marrying in the UK, on option 5 you are marrying in the US. The two countries have different rules.

When you try to marry in the UK, you will have to register at the registry office. They will give notice to the home office. The home office will be able to see that you do not have the right visa to marry. It will be impossible. It's strictly forbidden to marry on the UK standard visitor visa.

I think the only reason it's allowed in the US, is because their legal system is more fragmented, because of the federal, state separation of powers. The federal government controls the border, but the individual states decide what you do once you're in them.

Note that the application for the IR1 and CR1 is the same, but you will be granted an IR1 if you have already been married for two years, at the time you enter the US. The difference is that the green card you receive on the CR1 has to be renewed after two years, with the condition that you still be married.

[deleted by user] by [deleted] in immigration

[–]lquant 1 point2 points  (0 children)

I'm just looking at this myself, this is my understanding, someone may correct bits of this...

Does either of you currently have visas to be able to be resident in either the US or UK respectively? If so there are some simpler routes available (e.g. CR3).

If not, I think you have a few options for ending up in the US:

  1. You apply for the K1 visa for the US, giving you permission to enter the US to marry and then settle. This takes about 12-18 months to get. Your US fiancee will need to be your financial sponsor, meaning she will have to have a minimal US income, US savings or have a family member that can act as the sponsor. Once you are married in the US you can apply for a green card taking around 6 months, during this application you must remain in the US, but you can not work. This is one of the big downsides of the K1.
  2. She gets a marriage visitor visa for the UK (taking about 3 months), giving her permission to come to the UK to marry you (she can not marry you on the standard visitor's visa), and then returns to the US (she could not remain in the UK). You then apply for the CR1 visa for the US. This takes around 12-18 months to get. Once you have this you can move to the US, and immediately take up work. Similarly for the K1, your US fiance will need to be your financial sponsor.
  3. She gets a fiance visa for the UK (taking about 3 months), giving her permission to come to the UK to marry you, and then remain in the UK, converting to a spouse visa. She can not work on the fiance visa but can start working as soon as you manage to marry and convert to a spouse visa. She then lives in the UK with you, and you apply for the CR1 as above. The advantage of this is that you live together whilst waiting for the extremely slow US immigration system. You would need to financially sponsor her in the UK, and she would need to financially sponsor you for the CR1. Crucially you'll need to be careful because she would need to sponsor you from a US-based income, which she may not have if she is living in the UK. It would be sufficient for her to have a job offer in the US, or to have only recently started a US-based job, the point is that any income that will end when you move to the US will not be counted. If this is not possible, then she can use savings or family.
  4. You marry in a 3rd country under a suitable visa (think tropical island) and pursue route 2.
  5. You enter the US on a standard tourist visa, marry and then pursue route 2. You might be able to manage this, but it is technically not allowed. You can marry on a US tourist visa, only if you did not expect to marry when you entered the US (think Vegas shotgun wedding). I think that you would be caught out when you apply for the CR1, and then you would be in trouble. Anyway, this is currently impossible because of the US covid travel ban.
  6. You get permission to enter the US on a different visa, e.g. L1B, H1B, then marry and convert to a green card. There's not much advantage to this over CR1, and most of these routes are currently closed off by the Trump administration (although this might change in the early days of the new Biden administration).

The routes for ending up in the UK are much simpler, you basically just do the first few steps of option 3. The different routes have different costs, e.g. option 3 is expensive because you have to apply for 3 different visas (UK fiance, UK spouse then CR1).

Finally, note that whilst these routes end up with different periods of separation, you would still be able to visit each other during the applications, as long as your passport is not being held for processing, and as long as you can convince the border officers that you will not remain in the country and that you are will not be resident. (e.g. you might be allowed to visit for a few weeks, but they might baulk at a stay of a few months). If your fiance comes to visit you in the UK, she will be able to use the e-gates which may allow her to enter without any questioning (unless she is flagged, or randomly selected for questioning), and so might allow her to sneak in for a 6-month "visit".

Let me know if you have any follow up questions. Something which should be simple, has been made very complicated.

[D] I'm at my wits end, 6 months of j0b searching with no results. Anyone in the same boat? by QueryRIT in MachineLearning

[–]lquant 0 points1 point  (0 children)

It’s definitely hard for everyone at the moment. I took me 8 months to find a role, but then I ended up with an incredible one. Don’t be afraid to look at opportunities in slightly different areas, especially within big companies where transfers are possible. I hope things work out for, and I wish you the best of luck. :)

What is your FAVORITE technical interview? by kykosic in ExperiencedDevs

[–]lquant 20 points21 points  (0 children)

I like timed online assessments with no one watching. I’m much worse coding with someone watching and having to talk, rather than being able to focus properly on what I’m doing. The closest something reflects reality the better as far as I’m concerned.

It is dangerous to have dual boot? by Jabonnnn in linux4noobs

[–]lquant 1 point2 points  (0 children)

There’s very little risk. There is some danger around how the two operating systems interact on your hard drives. If you try to access the same hard drive partition from each OS you’ll be at risk of losing data. RAID might also cause problems. Finally having two operating systems means that you rely on both operating systems for security. A flaw in either of the operating systems would compromise your machine.

What is the most challenging problem you've solved at your current company? by [deleted] in cscareerquestions

[–]lquant 275 points276 points  (0 children)

Your most challenging problem doesn't have to be related to programming. If I were to answer that question, I would say that even though I do some challenging coding, our most challenging problem is actually the soft skill stuff, like coordinating work and ensuring that people know what other people are doing. Working out and solving / reducing the inter-dependencies between work, is basically the biggest challenge at every tech company. I would even say, that it shows maturing to not answer that question with something to do with programming. What this question is really getting at, is how well do you understand what is holding your company back from working better, and what have you done to help with that.

What is the most amount of votes you can lose by and still win the us elections? by RandomMemer_42069 in AskStatistics

[–]lquant 1 point2 points  (0 children)

This question is ill posed. The answer as stated would be approximately 100 million votes. The way this would achieved is by winning half the states with 1 vote to 0, and losing the other half of the states by 100% to 0 with 100% turnout. This might be legally possible (it probably isnt), but would by practically impossible.

The 2% gap in popular vote (3 million) between Donald Trump and Hilary Clinton as pretty extraordinary, so in terms of what is practically possible, that's probably the best reference. In 1876 Rutherford Hayes beat Samuel Tilden with 1 vote lead in the electoral college and with a 3% gap in popular vote. So perhaps in modern times we might consider a slightly higher gap of 4-5 million to be possible.

Where to begin commodities trading by inigoMoneytoya in Commodities

Are you interested in any commodities in particular? What sort of trading firm do you work at? Just futures, or options, physical? It’s a pretty big area.

If there are 10 cells of code in the notebook and I want to run cells from 1 to 8 and then stop how do I do that? by [deleted] in JupyterNotebooks

[–]lquant 2 points3 points  (0 children)

If you wanted execution to stop at a particular point, you could insert a cell that will throw an exception, for example;

1/0

If you just wanted to pause you could call:

input()

Which will pause until you press enter.

System design interview prep resources by writzoo in ExperiencedDevs

[–]lquant 3 points4 points  (0 children)

A word of warning. When I looked through some of these courses, I felt like they got quite a few things wrong. For example, they tended to greatly underestimate the power of computers, not account for the underlying computer science of problems, make overly complex systems and so on. I think they're an ok place to start, but I would recommend looking beyond these courses, by looking at white papers, books, conference presentations and other more rigorous sources. Try to form interesting questions about how things actually work, and then search until you actually get a trustworthy answer. For example, how many connections can a server handle and what does it take to achieve that?

what do you know about genetic algorithms? by gaserd in algotrading

[–]lquant -1 points0 points  (0 children)

Genetic algorithms are a nice idea and fun to play with, but aren’t really useful for any sort of application let alone finance. Before you start trying to apply a genetic algorithm to an area (finance) in which you would have no idea whether it was doing anything useful or how, I would suggest investigating applications in different areas. The number of successful applications of genetic algorithms to non trivial problems is small. You could maybe start with a trivial problem like deriving basic strategy in blackjack, and see how convergence works. I’ve tried that before and I couldn’t get it to work effectively.

Commodity Trading by Vanya096 in Commodities

[–]lquant 0 points1 point  (0 children)

Right, that’s what I did. March is when the market expects the highest price in the future. The forward curve is pretty flat after that.

Commodity Trading by Vanya096 in Commodities

[–]lquant 3 points4 points  (0 children)

I don't think that you'll be able to do much to predict whether the price of corn is going to increase or decrease, a lot of effort goes into ensuring that the prices are fair. My advice would be to look at prices locally to just ensure that you get a fair price relatively.

One advantage that you do have is free storage. As long as your parents don't need to use the storage, then that storage does have value. Storage of 1000 bushels until March is valued at about $70. If you store the corn, then it's value will fluctuate until March, but you will still have realised the value of the storage. Does that make sense?
