How to resolve any access in Azure Data Factory 2 to the Azure DevOps repository

I'm having a problem with Azure Data Factory when trying to access the Git Azure DevOps repository I've set up. The error message is: "Invalid GIT configuration." You must access the repository before you can publish the changes Details: Authentication Error – You do not have access to the provided Azure DevOps account. "

I use the same account on DevOps and Data Factory. My access to the Azure portal is "Contributor" at the subscription level and my DevOps role as a project administrator on the project.


I've tried different combinations to create the repository as new from Data Factory, as well as to use an existing repository created (by myself) in Azure DevOps.

From in Open Feedback elements, a user indicates that "the embedded role of Data Factory Contributor is not in the Allow portion:
Action: Microsoft.DataFactory / locations / configureFactoryRepo / action "
I have investigated the role of the contributor and the action seems to have been allowed as "Reading"?

Postfix SASL authentication error – resolve without a symbolic link?

Ubuntu 14.04.6 LTS
I receive the error message "SASL authentication failed: Can not connect to saslauthd server", where the typical fix is ​​a symbolic link.

sudo ln -s /var/spool/postfix/var/run/saslauthd /var/run

The problem is that I already have a symbolic link set to / var / run that points to / run. I do not remember why, but otherwise dozens of things get stuck, mysql, apache, etc.

Is there another way to resolve this error without the symbolic link?

Trying to understand why I have the original symbolic link means a lot more digs than what I want to do at the moment.

np complete – Why did not I resolve the problem of Traveling Salesman with the following argument using the djikstras algorithm?

I claim to have solved the problem of the traveling salesman as follows.

1) I'm about to start using the Djikstra algorithm on any road network, but

2) The end node is not known for the moment, no matter, I start from any arbitrary node, assuming that the final node will be given to me later or that I will will claim it myself.

3) At each step of the jikstra algorithm, you stop me, I claim that the last node that I am currently must be the final node I was looking for.

4) Whenever I am stopped, I am on the shortest possible path from my initial node to the current node under the jikstra algorithm (end node from djikstra's point of view)

5) I continue the process unless I start to reach each node.

6) There is only one endpoint left, and yet, the path I have chosen is the shortest possible path from the initial node to this node, and I have traveled all possible nodes.

7) I return to the initial node by traversing all the nodes with the shortest possible path.

Question: Why did not I solve the problem of the traveling salesman?

P.S. Please comment if my argument is not clear enough, I will try to clarify it. There is clearly a gap in my understanding of the theory and I want to understand what it is. I do not have enough computer experience to ask a question by algorithm.

usability – How to resolve the ambiguity of the selected state in a segmented control with only two segments?

I'm working on a web application with two similar data grids in one page. The user should be able to switch between these two data grids on the same page.

I've used segmented buttons to navigate between these two grids. But I think that this component visually becomes a seesaw and that the current state of the seesaw becomes ambiguous.

For now, I'm only relying on the color / hue to display the selected state, but I do not know which state to choose.

Is there a better approach to solve this problem?

bitcoin core – Resolve BTC long memory pool (lots of unconfirmed messages)

I started with the Bitcoin exchange service, creating rawtransaction and broadcasting it. The problem I have to deal with is the mempool string too long (more than 25 unconfirmed transactions), for example:
64: chain too long

Using limitancestorcount and limitdescendantcount Just solve on the local node, these late txs (transaction after the first 25) have to wait a long time to be rebroadcast like this:
Transaction not found in blockchain

Here is my testnet address has a lot of unconfirmed txs and still waiting, if I search on another explorer, I can not see 45 unconfirmed txs, same for getrawtransaction on the node, respose is No such mempool or blockchain transaction:

So, how can I avoid this problem, I just think of several methods, such as: divide the main address into a few sub-addresses, which divides the main UTXO into a few UTXOs, create a many-to-many transaction (currently 1 to 2, 1 target and 1 changeAddress back), using UTXO first with high confirmation, … Which options can bring better results and performance for a long scaling? term? Any advice is really appreciated. And last question, is there a way to mark 1 UTXO used 25 times (for example, I use UTXO X first, then it is returned, Y is used, Z is returned, total using X = 2, I have no related information to calculate it because the node returns, UTXO only contains txId).

Optical – How can I find the distance needed to resolve a point on a page from a mobile camera?

No, you can not know from the technical specifications you are thinking about. The resolution power of a camera system depends on how the lens is built and the properties of the recording medium, as well as other factors such as lighting and the atmosphere.

You may be able to get some details about the recording media – the sensor – from the camera specifications, but not enough to be really useful in practice. And for lenses, the resolving power is characterized by tests, not calculated in theory.

javascript – how to resolve the unexpected token or illegal return instruction

Good until here I learn and I handle the search and the promises. The problem is that I enter a new function and a new promise back below when I do not see the object. A new unexpected token appears to me.

var divus=document.querySelector("#usuarios");
    var Janet=document.querySelector("#Janet");
    var avatar=document.querySelector("#avatar");
            .then(data => data.json())
            .then(users =>{listadousuarios(;

            return getJanet();
            .then(data => data.json())
            .then(user => {

            return getInfo();
            .then(data =>{

                function getUsuarios(){
                    return fetch("");

                function getJanet(){
                    return fetch("");

                //nueva promesas
                    function getInfo(){
                        var informacion = {
                            nombre: 'Sebastian',
                            Apellidos: 'Zamora Urrego',


                    return new Promise((resolve, reject))=> {
                            var info_string = JSON.stingify(getInfo);
                            if(typeof info_string != "string")return reject(error);

                            return resolve(info_string);
                function listadousuarios(usuarios){

          , i) => {
                    let nombre= document.createElement("h3");

                    nombre.innerHTML=i + user.first_name + " " + user.last_name;
                function Ujanet(user){


                    let nombre= document.createElement("h3");
                    nombre.innerHTML=user.first_name + " " + user.last_name;

But when I close it, an illegal return statement appears, I guide myself through an online course and the teacher uses it in the first way and it does not get any error.

//nueva promesas
                function getInfo(){
                    var informacion = {
                        nombre: 'Sebastian',
                        Apellidos: 'Zamora Urrego',

I would appreciate any help

How to resolve the 404 error on the site?

Hello friends,

How to resolve the 404 error on the site?

operating systems – Resolve Windows 7 Resume

I have a Windows 7 desktop. Today, when I tried to start it. A black screen appeared.
With option

1] continue with recovery data
2] delete the restore data and move to the system boot menu

But the keyboard and the mouse do not work

I tried with these methods
1] Remove the battery from the motherboard and replace it again. And a screen appeared for the configuration of the bios. I've tried all the options. But when the PC restarted. The same screen appeared

I've read in posts that it's because of the corruption
hiberfil.sys file.
My question now is whether I'm using my hard drive enclosure and my current hard drive as an external hard drive on another computer. And from there, I delete the hiberfil.sys file.
1] Will it delete all files from my hard drive?
2] Will I be able to start my PC when I put it in the previous PC
