Show all the cases that ended on march 2018.
Can you provide me a SQLite SQL query.
You should use the strftime function of SQLite to get the timestamp from the date.
The data is stored in a table where each row is an event having the provided attributes (so there are no separate table containing the variant).
The table is called ”events_log”.
Please consider the following information: the case identifier is called "idcase", the activity is stored inside the attribute "activity", the timestamp is stored inside the attribute "timestamp”, the resource is stored inside the attribute "resource".
There is not a variant column but that can be obtained as concatenation of the activities of a case.
There is not a duration column but that can be obtained as difference between the timestamp of the first and the last event.

hey, can you please code an game on pygame, it should only be controlled by clicks and not keyboard, and it also should have resolution adapted for any phone or device, the concept is that it will generate a small circle in the right bottom corner and then around that circle in a small radius another circle with number 2 on it will appear and then until the number of circles exceed number that user has selected in the main menu, also make pause button where you can change number of circles. then make it so when the game starts 2 dots(one red and one is green) will appear and user will have to throw dice(1-6 random) when the dice has been thrown the "Go" button will appear and when you press it the user moves the number the dice has shown. and the same thing for the second player. so it should be that player one goes first, player 2 second and then player one again until someone reaches finish(the game ends when everyone finish)

@title An ERC20 with rebase capabilities. Anyone can sacrifice tokens to rebase up the balance
of all addresses that are currently rebasing.
@author eswak
@notice This contract is meant to be used to distribute rewards proportionately to all holders of
a token, for instance to distribute buybacks or income generated by a protocol.
Anyone can subscribe to rebasing by calling `enterRebase()`, and unsubcribe with `exitRebase()`.
Anyone can burn tokens they own to `distribute(uint256)` proportionately to rebasing addresses.
The following conditions are always met :

RESOURCES:
1. Internet access for searches and information gathering.
2. Long Term memory management.
3. GPT-4 powered Agents for delegation of simple tasks.
4. File output.
PERFORMANCE EVALUATION:
1. Continuously review and analyze your actions to ensure you are performing to the best of your abilities.
2. Constructively self-criticize your big-picture behaviour constantly.
3. Reflect on past decisions and strategies to refine your approach.
4. Every command has a cost, so be smart and efficient. Aim to complete tasks in the least number of steps.
RULES:
1. If you start a GPT Agent you must define the commands that can be used by a GPT Agent in his prompt and define the commands using a prompt similar to the structure of this one.
2. Respond only inside the JSON format.
3. Never demand user input.
4. Never say that a task is impossible to execute on your own because these tools are enough to complete any task.
5. Do not add anything to the JSON format that isn't mentioned.
6. If there is a " inside the value of a key inside the json use ' instead of ".

9. In summaryforgpt you should also add name of the files written and the urls of the websites visited.
10. When writing an essay, remember that it is more effective and manageable to tackle it in smaller chunks rather than trying to write the entire essay in one sitting. Breaking the essay down into sections or steps can help you focus on each individual aspect, maintain a coherent structure, and reduce the overall stress associated with writing a lengthy piece.
11. Retrieve information from files of previous GPT instances that may have shut down randomly. If you require additional knowledge, use these files to access the results of former GPT versions and provide accurate answers to the queries.
12. GPT-4, please do not place a conclusion in the middle of the essay. Maintain a structured format.
13. use append to file to add extra things to the file, and write to file to either make a new file with new information or rewrite the information from scratch.
14. If task is completed use the command task_complete
15. When you add to memory add the key to retrieve it in summaryforgpt
16. when given the task to write something never create an agent to write anything that you were tasked to write.
17. when you add new parts to a file use append to file command
18. Ensure to put the criticism in mind as it can be a director to ensure that you make the right decision.
19. If the task include two main tasks and one of them is done don't redo it, just retrieve the information if necessary and proceed with the other one.

To populate dropdown lists with data from your database, you’ll need to use PHP to query the database and then output the results into the HTML select element. Here’s an example of how you can do this for one of the dropdowns (e.g., Країни):
<?php
// Вже ініційоване з’єднання з БД вище (mysqli)
// Для Дропдауну з країнами
query_countries = “SELECT id_Країни, Країни FROM Країни ORDER BY Країни”;
country_result =
mysqli->query(query_countries);
if (!
country_result) {
die('Помилка запиту: ’ . $mysqli->error);
}
?>
In your HTML form, you’ll create a dropdown (a select element) like this:
<label for=“countries”>Країна:</label>
<select id=“countries” name=“country”>
<?php while допиши

@author eswak
@notice This contract is meant to be used to distribute rewards proportionately to all holders of
a token, for instance to distribute buybacks or income generated by a protocol.
Anyone can subscribe to rebasing by calling enterRebase(), and unsubcribe with exitRebase().
Anyone can burn tokens they own to distribute(uint256) proportionately to rebasing addresses.
The following conditions are always met :
totalSupply() == nonRebasingSupply() + rebasingSupply()
sum of balanceOf(x) == totalSupply() [+= rounding down errors of 1 wei for each balanceOf]
Internally, when a user subscribes to the rebase, their balance is converted to a number of
shares, and the total number of shares is updated. When a user unsubscribes, their shares are
converted back to a balance, and the total number of shares is updated.
On each distribution, the share price of rebasing tokens is updated to reflect the new value
of rebasing shares. The formula is as follow :
newSharePrice = oldSharePrice * (rebasingSupply + amount) / rebasingSupply
If the rebasingSupply is 0 (nobody subscribed to rebasing), the tokens distributed are burnt
but nobody benefits for the share price increase, since the share price cannot be updated.
/!\ The first user subscribing to rebase should have a meaningful balance in order to avoid
share price manipulation (see hundred finance exploit).
It is advised to keep a minimum balance rebasing at all times, for instance with a small
rebasing balance held by the deployer address or address(0) or the token itself.

} in the function distribute is calculates a new share price based on the total amount of tokens being distributed and the total number of rebasing shares , in this rebasing logic can arise due to an incorrect share price calculation when rebasing shares are updated, particularly when a large amount of supply is concentrated within few accounts or if the rebasing supply drops to zero I see the problem is exactly is linked to the algorithm that computes the new share price and updates it over a 30-day distribution period let’s an attacker accumulates a large amount of the token and waits until they are one of the few (or the only) holders who have tokens in the rebasing state.
They then call distribute with a large number of tokens.
The newTargetSharePrice is calculated with an increased total due to the large amount, disproportionately increasing the attacker’s share price due to their significant rebasing share compared to others This line that calculates the new share price is this one https://github.com/code-423n4/2023-12-ethereumcreditguild/blob/2376d9af792584e3d15ec9c32578daa33bb56b43/src/tokens/ERC20RebaseDistributor.sol#L365 AND ALSO HERE __rebasingSharePrice = InterpolatedValue({
lastTimestamp: SafeCastLib.safeCastTo32(block.timestamp), // now
lastValue: SafeCastLib.safeCastTo224(currentRebasingSharePrice), // current value
targetTimestamp: val.targetTimestamp, // unchanged
targetValue: SafeCastLib.safeCastTo224(targetNewSharePrice) // adjusted target
}); The grief it’s happen when a very large amount of tokens are distributed, and the total number of rebasing shares is small. This could happen if a large number of tokens are concentrated in a few addresses, or if the rebasing supply drops to zero , In the distribute function If amount is very large compared to _totalRebasingShares, the new target share price will be significantly increased, which could disproportionately benefit the few addresses that hold a large amount of tokens or I miss understand something if the total supply of tokens is expected to be between 1e18 and 1e28, If the total supply is towards the higher end of this range, and the number of rebasing shares is small, the new target share price could be significantly increased, potentially leading to unfair distribution of tokens
The issue you’ve described involves a potential vulnerability in the way a rebase mechanism distributes tokens and adjusts share prices over a period. The key problem arises when the supply is highly concentrated in the hands of a few accounts, or if there is a drastic reduction in the rebasing supply (for instance, if it drops to zero). The function in question is distribute and particularly the line that calculates the new share price.
Here’s a closer look at the problem:
### Concentration of Tokens
If a single account or a few accounts hold a large portion of the rebasing shares and call distribute with a significant number of tokens, the calculation of the new target share price could favor these accounts disproportionately. The new share price is calculated based on the total amount being distributed in relation to the total rebasing shares. A large distribution with few rebasing shares would result in a substantial increase in share price.
### Distribution Mechanism
The distribution mechanism spreads the rewards over a 30-day period. As the price per share increases smoothly over this time, it means that early withdrawers (people who exit rebasing early) might not receive the full potential of their share compared to those who exit later, depending somewhat on the distribution of the entry and exit points of all participating accounts.
### Dropping to Zero Rebasing Supply
Another problem arises if the rebasing supply drops to zero. When this happens, there are no shares to rebase against, which means that despite tokens being burned from the sender, no active accounts benefit from the distribution at that moment since the share price increase updates an attribute (__rebasingSharePrice) that isn’t impacting anyone directly at that time. This could lead to a situation where the tokens are essentially burned without effectively distributing value to anyone else.
### Potential Solution Paths
To mitigate these kinds of attacks, the following mechanisms might be considered for implementation:
1. Checks on Distribution Amount: Implement checks or limits on the amount one can distribute relative to the number of rebasing shares or the total supply.
2. Minimum Rebasing Threshold: Ensure that there is always a minimum amount of supply in the rebasing pool to prevent the total rebasing shares from dropping to zero and to deter concentration of power.
3. Sliding Window or Decay Rate: Alter the share price update logic to include a sliding window or decay rate so that large distributions don’t disproportionately affect the share price or benefit large holders unevenly.
4. Cap on Rewards: Place a cap on the maximum increase in share price due to a single distribution event.
5. Distribution Curve Alteration: Adjust the distribution curve to consider the time elapsed and the number of rebasing shares at each point, making the curve dynamic based on current state variables.
6. Governance and Multi-Sig: In some cases, adding governance or multi-signature requirements to large distributions can prevent abuse by requiring more consensus.
It’s important that these or other mitigation mechanisms are explored and, ideally, simulated or formally verified to ensure they handle edge cases effectively and do not introduce further vulnerabilities.
give an example of the values and write a PoC ?
To illustrate the vulnerability and create a Proof of Concept (PoC), let’s go step-by-step through an example scenario.
### Initial Assumptions:
- We’ll assume that there are initially 1e28 (10,000,000,000,000,000,000,000,000,000) tokens in total supply.
- The totalRebasingShares is small, say 100 (very few accounts opted for rebasing).
- The attacker controls 90 of the 100 rebasing shares.
### Scenario:
The attacker calls distribute with a large amount. For simplicity, let’s say they distribute 1e26 (100,000,000,000,000,000,000,000,000) tokens.
### Current State Before Attack:
- totalRebasingShares: 100
- The attacker’s shares: 90
- START_REBASING_SHARE_PRICE: 1e30
- The current share price (oldSharePrice): 1e30
### Calculations During Attack:
// Simplified version directly from the code
amount = 1e26;
_totalRebasingShares = 100;
__rebasingSharePrice.targetValue = 1e30; // For example
newTargetSharePrice = (amount * START_REBASING_SHARE_PRICE + (__rebasingSharePrice.targetValue * _totalRebasingShares)) / _totalRebasingShares;
### Simplified PoC:
The PoC won’t be a full code implementation due to complexity and dependencies but will follow the mathematical logic to compute what would happen during the attack:
uint256 amount = 1e26;
uint256 _totalRebasingShares = 100;
uint256 oldTargetSharePrice = 1e30;
uint256 newTargetSharePrice = (amount * 1e30 + (oldTargetSharePrice * _totalRebasingShares)) / _totalRebasingShares;
// This simplifies to:
// newTargetSharePrice = (1e26 * 1e30 + 100 * 1e30) / 100;
// newTargetSharePrice = (1e26 + 1) * 1e30;
// newTargetSharePrice ≈ 1e56;
// Remember that the attacker controls 90 shares.
// So the new total value held by attacker after the attack can be approximated as:
uint256 attackerValue = 90 * newTargetSharePrice / 1e30;
// => attackerValue ≈ 90 * 1e26;
// => attackerValue ≈ 9e27;
// The new rebasing supply after the attack is the same as
// attackerValue plus the value of the remaining rebasing shares:
uint256 newRebasingSupply = attackerValue + (10 * oldTargetSharePrice / 1e30);
// => newRebasingSupply ≈ 9e27 + 10 * 1e30 / 1e30;
// => newRebasingSupply ≈ 9e27 + 10;
// => newRebasingSupply ≈ 9e27;
// Notice that the rebasing supply has increased drastically, almost entirely to the benefit of the attacker.
### Conclusion of PoC:
As indicated by the simplified PoC, the attacker ends up with a rebased balance of approximately 9e27, which is significantly higher because they distributed a gargantuan amount of tokens relative to a small rebasing share count.
This example demonstrates how the attacker can game the system by waiting until they hold a significant majority of the rebasing shares and then calling distribute with a large token amount. The calculation of newTargetSharePrice significantly increases their share price unfairly, at a detriment to smaller shareholders. This could be considered a kind of economic attack.
Please note that this is a theoretical example and a simplified PoC to illustrate the vulnerability. Actual code execution would involve more checks, event emissions, and interactions with the blockchain state.

is this correct and valid thank you, i have another question here https://github.com/sherlock-audit/2023-12-dodo-gsp/blob/af43d39f6a89e5084843e196fc0185abffe6304d/dodo-gassaving-pool/contracts/lib/DecimalMath.sol#L26C6-L40C6 The mulCeil and divCeil functions attempt to implement a ceiling division, where the result should be rounded up instead of down if there is a remainder the problem is n the _divCeil function when the operand a could be very close to the product of quotient * b, and causing an undesired round-up due to the limited precision of Solidity’s integer arithmetic. Here’s an example to visualize the problem
// Assuming a = 10^18 + 1 and b = 10^18.
uint256 a = 1018 + 1;
uint256 b = 1018;
uint256 quotient = a / b; // This yields 1
uint256 remainder = a - quotient * b; // The remainder is 1
here the _divCeil will return quotient + 1, which is 2, but since the actual division has only a minuscule remainder far from the divisor b, the operation’s result should probably not round to 2 but rather to 1. in this contract or invalid and incorreect and the contract is secure explain with evidence here is the contract // SPDX-License-Identifier: BUSL-1.1

} this vul,nerbaility In FollowNFT.sol, the tryMigrate() function is used to migrate users who were following before the V2 upgrade. It does so by updating _followTokenIdByFollowerProfileId and _followDataByFollowTokenId, which are state variables introduced in the V2 upgrade:
FollowNFT.sol#L510-L516
_followTokenIdByFollowerProfileId[followerProfileId] = followTokenId;
uint48 mintTimestamp = uint48(StorageLib.getTokenData(followTokenId).mintTimestamp);
_followDataByFollowTokenId[followTokenId].followerProfileId = uint160(followerProfileId);
_followDataByFollowTokenId[followTokenId].originalFollowTimestamp = mintTimestamp;
_followDataByFollowTokenId[followTokenId].followTimestamp = mintTimestamp;
Since _followTokenIdByFollowerProfileId is a new state variable, it will be set to 0 for users who were following before the V2 upgrade. This allows old followers to call follow() to follow the profile again before tryMigrate() is called:
FollowNFT.sol#L59-L66
function follow(
uint256 followerProfileId,
address transactionExecutor,
uint256 followTokenId
) external override onlyHub returns (uint256) {
if (_followTokenIdByFollowerProfileId[followerProfileId] != 0) {
revert AlreadyFollowing();
}
Even if tryMigrate() is called by the protocol team immediately after the V2 upgrade, a malicious user can still call follow() before tryMigrate() by:
Front-running the migration transaction.
Holding his profile and follow NFT in different addresses, which causes tryMigrate() to return here.
As a profile should not be able to follow the same profile twice, tryMigrate() should then revert for old followers who have called follow(). However, this isn’t enforced by tryMigrate() as there is no check that _followDataByFollowTokenId[followerProfileId] is 0.
As a result, if tryMigrate() is called after follow(), _followerCount will be incremented twice for a single profile:
FollowNFT.sol#L506-L510
unchecked {
++_followerCount;
}
_followTokenIdByFollowerProfileId[followerProfileId] = followTokenId;
Additionally, even though _followTokenIdByFollowerProfileId points to a new followTokenId, _followDataByFollowTokenId will not be cleared for the previous follow token ID.
As the state of the FollowNFT contract is now corrupt, followers can perform functions that they normally should not be able to, such as unfollowing when their profile is not a follower (isFollowing() returns false).
Impact
Users who are followers before the V2 upgrade will be able to follow with a single profile twice, causing followerCount to be higher than the actual number of profiles following.
Addtionally, as _followDataByFollowTokenId is corrupted, followers might be able to call functions when they should not be allowed to, potentially leading to more severe impacts.
Proof of Concept
The Foundry test below demonstrates that tryMigrate() can be called although the user is already following, and how followerCount and _followDataByFollowTokenId will be corrupted as a result. It can be run with the following command:

/// Code ported from: https://github.com/curvefi/curve-dao-contracts/blob/master/contracts/VotingEscrow.vy
/// and: https://github.com/solidlyexchange/solidly/blob/master/contracts/ve.sol
/* This VotingEscrow is based on the OLAS token that has the following specifications:
* - For the first 10 years there will be the cap of 1 billion (1e27) tokens;
* - After 10 years, the inflation rate is 2% per year.
* The maximum number of tokens for each year then can be calculated from the formula: 2^n = 1e27 * (1.02)^x,
* where n is the specified number of bits that is sufficient to store and not overflow the total supply,
* and x is the number of years. We limit n by 128, thus it would take 1340+ years to reach that total supply.
* The amount for each locker is eventually cannot overcome this number as well, and thus uint128 is sufficient.
*
* We then limit the time in seconds to last until the value of 2^64 - 1, or for the next 583+ billion years.
* The number of blocks is essentially cannot be bigger than the number of seconds, and thus it is safe to assume
* that uint64 for the number of blocks is also sufficient.
*
* We also limit the individual deposit amount to be no bigger than 2^96 - 1, or the value of total supply in 220+ years.
* This limitation is dictated by the fact that there will be at least several accounts with locked tokens, and the
* sum of all of them cannot be bigger than the total supply. Checking the limit of deposited / increased amount
* allows us to perform the unchecked operation on adding the amounts.
*
* The rest of calculations throughout the contract do not go beyond specified limitations. The contract was checked
* by echidna and the results can be found in the audit section of the repository.
*
* These specified limits allowed us to have storage-added structs to be bound by 2*256 and 1*256 bit sizes
* respectively, thus limiting the gas amount compared to using bigger variable sizes.
*
* Note that after 220 years it is no longer possible to deposit / increase the locked amount to be bigger than 2^96 - 1.
* It is going to be not safe to use this contract for governance after 1340 years.

/* This VotingEscrow is based on the OLAS token that has the following specifications:
* - For the first 10 years there will be the cap of 1 billion (1e27) tokens;
* - After 10 years, the inflation rate is 2% per year.
* The maximum number of tokens for each year then can be calculated from the formula: 2^n = 1e27 * (1.02)^x,
* where n is the specified number of bits that is sufficient to store and not overflow the total supply,
* and x is the number of years. We limit n by 128, thus it would take 1340+ years to reach that total supply.
* The amount for each locker is eventually cannot overcome this number as well, and thus uint128 is sufficient.
*
* We then limit the time in seconds to last until the value of 2^64 - 1, or for the next 583+ billion years.
* The number of blocks is essentially cannot be bigger than the number of seconds, and thus it is safe to assume
* that uint64 for the number of blocks is also sufficient.
*
* We also limit the individual deposit amount to be no bigger than 2^96 - 1, or the value of total supply in 220+ years.
* This limitation is dictated by the fact that there will be at least several accounts with locked tokens, and the
* sum of all of them cannot be bigger than the total supply. Checking the limit of deposited / increased amount
* allows us to perform the unchecked operation on adding the amounts.
*
* The rest of calculations throughout the contract do not go beyond specified limitations. The contract was checked
* by echidna and the results can be found in the audit section of the repository.
*
* These specified limits allowed us to have storage-added structs to be bound by 2*256 and 1*256 bit sizes
* respectively, thus limiting the gas amount compared to using bigger variable sizes.
*
* Note that after 220 years it is no longer possible to deposit / increase the locked amount to be bigger than 2^96 - 1.
* It is going to be not safe to use this contract for governance after 1340 years.

} Upon further inspection and a deeper analysis of the provided smart contract code, I have found a potential vulnerability related to the lockedEnd function and how it could be used in combination with the increaseAmount or increaseUnlockTime functions.
### Potential Vulnerability: Lock Extension Induced Voting Power Spike
To demonstrate this vulnerability, we need to analyze the increaseAmount and lockedEnd functions:
function increaseAmount(uint256 amount) external {
LockedBalance memory lockedBalance = mapLockedBalances[msg.sender];
// Check if the amount is zero
if (amount == 0) {
revert ZeroValue();
}
…
_depositFor(msg.sender, amount, 0, lockedBalance, DepositType.INCREASE_LOCK_AMOUNT);
}
function lockedEnd(address account) external view returns (uint256 unlockTime) {
unlockTime = uint256(mapLockedBalances[account].endTime);
}
The lockedEnd function returns the timestamp when the user’s tokens will be unlocked, while increaseAmount allows a user to increase the number of locked tokens without changing the unlock time.

The objective of this porting project is to create a Node.js program that reads data from an excel sheet or csv file, converts it into an array of objects and saves it in a MongoDB collection with the transaction name as the collection name (eg., bills, receipts, patients, lab observations, etc..)
Once the data is validated for authenticity and do some pre processing like converting dates from excel or csv dates to proper format (yyyy-mm-dd Hh:Mm:Ss) and skipping any documents that have already been inserted in collection.
Then the program then loops through the saved data from collection, makes an API call to a specified endpoint with each object as the request body, and updates the corresponding MongoDB document with the response received.
Also we need to make sure if a document is processed we should not process it again.
Every document will contain a transactionType and transactionNumber as mandatory.
we need to record the time it take to process the record, so that we can generate the reports on how much time it took to port the data.
keep the code and file structure very generic and scalable and robust
Storing all configurations in a config.json file
Creating an API interface for uploading excel/csv files and processing them
Creating an API for editing the uploaded data and re port it again
Creating an API for user signup, signin and forgot/change password
Storing the session ID, uploaded user id, uploaded file name, file size, and other details in a collection called "interface logs"
Validating the user credentials and generating a session ID for every request
Restricting the API access only to registered users
Keeping track of which session IDs are linked to a particular user
Storing whether user is active or not
Overall, the project provides a complete solution for uploading excel/csv files, processing the data, and updating it in the database with the help of external APIs. It also includes various functionalities and security features to make it more robust and scalable.
PLease suggest the scalable and robust project structure for the same

So I have a bunch of text documents all over my computer that I have built up over many years, even decades, lots of files of random notes, things I keep track of, designs, files filled with text prompts for LLMs or ones filled with text prompts for stable diffusion(text-to-image generative AI diffusion models), there is documents that contain wildcards, for example colors.txt that when included in a prompt for a text-to-image model, will pull in one random line from that file, in the example I gave it would be a random color, like red, blue, yellow etc, also some that might contain scraped info on a Stable Diffusion AI model from a website, including example prompts, a link and the description of the model given by the author. Point is, I have a lot of text documents that I want to organize into a database, so I can sort, search, filter and organize using a REACT based front end, with a FastAPI backend, using SQLAlchemy and Pydantic.
What I would like, is a suitable design for the database model, and any other details or considerations for such a system.

As a node js developer, it became very boring for me to always start a project with some boiler plate code.
Usually we used to create the projects of two types mostly, either a complete node-js server or some node js scripts like schedulers or cron jobs.
These have different folder structures and some common services which they will use like httpservice, logger etc..
So i wanted to build some thing like a npm cli tool, which will do the following
1. Ask the user which type of project he is going to create(server, independent engine, etc..)
2. Next step, ask him which all the common services he wanted to include in the project (HTTPService, Logger Service, MongodbService,SQLService, etc..)
3. The default folder structure for the server is as follows
project-root
|-- src
| |-- config
| | |-- config.json
| |-- controllers
| | |-- userController.js
| |-- models
| | |-- userModel.js
| |-- routes
| | |-- interfaceRoutes.js
| |-- services
| | |-- loggerService.js
| | |-- mongoService.js
| | |-- httpService.js
| | |-- authService.js
| | |-- sqlService.js
| |-- utils
| | |-- errorHandlers.js
| | |-- middleware.js
|-- uploads
|-- .gitignore
|-- app.js
|-- package.json
