kandi X-RAY | contracts Summary
The first application launched by Alice uses smart contracts to implement a "pay for success" donation model, where donors only pay if the charitable projects they give to achieve their goals. Each charity project encodes a list of "goals" that the charity aims to achieve, and each goal is assigned a price that the charity will receive if/when the goal is provably achieved. Donors give to projects on the Alice platform using fiat, and the payment logic is implemented on the blockchain using a stablecoin token pegged to the value of their gift. When a donor sends money to a project, the corresponding amount of tokens is minted and credited by the Charity contract. These tokens are held in escrow until a dedicated Validator confirms that an expected goal pursued by the charity has been achieved. Once this validation has been performed, the price assigned to the goal is then transferred to the charity's account. If the charity does not achieve any goals, outstanding tokens are unlocked and returned to donors. They can then be reused for future donations.

QUESTION
Can someone help me investigate why my Chainlink requests aren't getting fulfilled. They get fulfilled in my tests (see hardhat test etherscan events(https://kovan.etherscan.io/address/0x8Ae71A5a6c73dc87e0B9Da426c1b3B145a6F0d12#events). But they don't get fulfilled when I make them from my react app (see react app contract's etherscan events https://kovan.etherscan.io/address/0x6da2256a13fd36a884eb14185e756e89ffa695f8#events).
Same contracts (different addresses), same function call.

I'm trying to create a few generic recursive types to modify structure of existing types. I can't tell why the sections inferring arrays and nested objects is not getting triggered. Any idea what I'm doing wrong?

...ANSWER
Answered 2021-Jun-15 at 00:56Assuming what I mentioned in my comment on your question, the fix is just to simplify your FieldWithConfidence type significantly. Right now it is trying to add a number of additional levels of structure beyond what you seem to want. Here is a version of that type that works as I think you intend:

...ANSWER
Answered 2021-Jun-14 at 11:51This is happening because there is no Transaction opened in DTO(object become detached). Wherever you have fetched the object from the DB call contractFile.getContract() so that the ORM framework loads the lazy-loaded object.

My application is returning an error when storing the cache, I saw that it was saving, but it is returning this error. Can anyone say why? Here's my function and the error:

...ANSWER
Answered 2021-Jun-12 at 21:26After thinking a little bit, I think I know what your problem is, you are using function ($keywords), but you should be using function () use ($keywords) because, in the source code, you see that it is doing $value = $callback(), but your function is awaiting $keywords, if you want to share a value, you have to use use ($keywords) again, like your second function in the where.
So, it should be:

QUESTION
I'm looking how to delete something from a table where the result from another query on another table.
I need to delete from "contract" where id is equal to the id of the user, where the email is equal to email@gmail.com.
Something like " DELETE FROM contract WHERE user = (SELECT id FROM users WHERE email = 'testuser****@mailinator.com') "
So I can delete all the contracts from user 3 but without using it's id because I just know the email. (I seed the testusers with a script so I have the email but no the id)

QUESTION
not so long ago I started to practice with writing EOS smart contracts on my windows 10 computer. For this I needed to install among others, a Linux subsystem for Windows and Docker. In the last couple of days I noticed some pretty significant performance issues, when looking for the perpetrator in my task manager I came across Vmmem using up 1.8 GB of ram (which is quite a lot considering I have only 8GB on my laptop):
I Googled around some and figured out that this program handles virtual machines and such, and with that Docker. I don't have Docker Desktop or Ubuntu opened at the time of this screenshot, turned off the setting "Start Docker when you log in" and restarted my computer, but still this program is hogging up my RAM. As you may understand, it isn't worth it for me to keep this running in the background considering this EOS Development is a side-thing for me, hence I don't need to use Docker often. I would deem it a shame if I had to give up on this 'hobby' for performance issues so any help would be appreciated.
...ANSWER
Answered 2021-May-15 at 22:48As @Matze suggested, I made a .wslconfig file in my home directory restricting the memory usage, which solved the problem.

Answered 2021-Jun-12 at 00:19With @url http://www.amazon.com/s?field-keywords=selfish+gene I get also error 503.
Probably it is very old example - it uses http but modern pages use https - and amazone could rebuild page and now it has better system to detect spamers/hackers/bots and block them.
If I use @url http://toscrape.com/ then I don't get error 503 but I still get other error FAILED because it needs some code in parse()
