Real Time Stocks price and technology to implement

2022.01.26 07:52 al0890 Real Time Stocks price and technology to implement

Hi guys. I’m studying how to implement real time stocks price in an app. Now, I know the best way to achieve this result is to use web socket, and it’s fine. My questions are: 1. Is there another way to do it? 2. Do you have alternative suggestions? 3. Do you know financial APIs that are free or that have a reasonable price for a personal project (that could scale maybe in the future)? Of course that offers the web socket, if possible.
Thank you!

2022.01.26 07:52 jellyboyyy Im still developing my Solidity security knowledge. Can anyone comment on my approach to multiple contract dApps?

I've been working on a dApp that has started to exceed the byte code size limit for smart contracts. Therefore I'm splitting it into more manageable chunks.
I'm doing this by having an interface in my main contract and using that to call the functions of the second contract. The main contract has an address variable for the second contract, which can only be modified by the owner. The second contract has an address variable for the main contract, which can also only be modified by the owner. This links the two contracts together.
Then in order to restrict direct access to the second contract, all external functions in the second contract require msg.sender to be the main contract. Therefore, all transactions need to be initiated by the main contract.
I suppose my real question is whether there are any security concerns with using msg.sender this way?
This method also allows me to upgrade either contract if necessary, but changes to the second contract are limited to the functions in the interface, so not really that upgradeable. Are there more flexible ways to do this?
Thanks for any help and advice you can give.

2022.01.26 07:52 rh204214 Getting a job in urban design with no masters or portfolio

I’m currently in my 1st year of studying a masters course in Urban Design and Planning. My course is 2 years because I’m doing it alongside working full time.
I work as a Planning Officer and am hoping to transition into working in urban design. However pretty much all of the urban design jobs I look at say you have to have graduated from the masters and /or have an extensive portfolio. I have neither of these. I have only done one urban design project which was submitted recently, so hasn’t even been graded yet. Therefore I have no idea if the work I completed for that project is to a good standard.
I was wondering if anyone had any tips for getting a job in urban design without having graduated from the masters and without having a portfolio? I’m willing to wait until I graduate from the masters to transition into urban design, but I find working as a planning officer very monotonous and unfulfilling, so it would be great if I could make the transition into urban design before I graduate. Also if I went into urban design I might have to take a pay cut because I would be starting right at the bottom, so the sooner I can get into that sector and build up my experience/ salary the better.

2022.01.26 07:52 niray5 please help please!!!

long story short, I have my boyfriend's instagram, the only thing is that he told me is not to look at messages between him and his male friends.
I haven't looked for years and for some reason I looked the other day (whyyy). anyways, I saw that they send pictures of women, and I saw that my bf also sends those and commented something like wow so hot.
This really hurt me and I couldn't go on with my life without telling him what I saw and that it hurt me. The only problem is that I couldn't say that I went into the messages because it's a red line for him, so I said that it opened accidentally.
anyways, he said sorry and told me that he believes me 100% and is sure that it happened accidentally.
Now I feel like a horrible person, I feel as if I cheated and I feel like if I can lie like that, then I'm also am going to cheat and do horrible stuff in the future.
I have to say I never lied to him in my life.
I feel like I have to tell him the truth, but that is gonna be bad and maybe lead to a breakup or him not trusting me again.
what should I do :(

(I have ROCD in general so that is why i wrote that in this group, as I what people to comment from a ROCD perspective)

2022.01.26 07:52 luis200014 Rompi o contrato de estágio, a empresa não quer pagar os dias trabalhados.

Então, recentemente pedir o desligamento nessa empresa da qual eu fazia estágio. Os motivos era, eles sempre pagavam a bolsa atrasado, já cheguei a receber no dia 20. Esse foi um fator que me fez procurar uma melhora, e recentemente consegui um estágio em outro lugar.
Por mais que seja só uma bolsa simples e pequena, de R$ 660,00 ela ajuda muito aqui em casa.
A grande questão é, sai de lá mês passado e até agora eles não me pagaram, provavelmente por raiva de eu ter quebrado o contrato e saído de lá.
Gostaria de saber o que posso fazer nesse caso, pois a única exigência que eu estou fazendo é o pagamento dos dias trabalhados e o valor proporcional as férias desse período. Pois trabalhei até meados do dia 20 praticamente o mês todo.
