| Anchor Tag for certain section: Working within the current screen but doesn't work as a link? Posted: 12 Aug 2021 07:49 AM PDT I currently have a file called Illustrations.js and exported it in a Storybook JS project as a story. My page is supposed to be a documentation page and I want to have anchor tags so that when the user clicks on it, it jumps to that section and users can also copy and paste the link and it will automatically go to that section. This is what my code looks like: <div className="template-section-header" id="product_illustrations"> Product Illustrations <a href="#product_illustrations" target="_self"> <img className="link-icon" src={iconsystemlink} /> </a> </div>
When I click on the link, it jumps to that section which is what I want. That part is working as intended. Before clicking on the anchor tag (the url is currently: http://localhost:9001/?path=/story/ccfk-%F0%9F%91%8B-%E2%A0%80templates--illustrations After clicking on the anchor tag (the url is still the same as above but clicks to that section 
However thought when I crtl-click or copy and paste the link in a new tab. It only shows the top of the page. When you copy and paste the link you get this. It just displays the top of the page (the url of the actual link itself is (http://localhost:9001/iframe.html?id=ccfk-%F0%9F%91%8B-%E2%A0%80templates--illustrations&viewMode=story#product_illustrations) 
I'm really confused on why this is so and any help or suggestions would be appreciated. Thank you  |

| Regex: the last match before the first match of a specific token Posted: 12 Aug 2021 07:49 AM PDT I'm quite new to regex, there's my example: <a href="https://www.wb1.com">Pie</a> <a href="https://www.wb2.com">Banana</a> <a href="https://www.wb3.com">Apple</a> <a href="https://www.wb4.com">Source</a> <a href="https://www.wb5.com">Source</a>
I want to get the URL for the first occurrence of Source tohttps://www.wb4.com. However, if I use <a href=(?s:.+?)Source<\/a> to find it, it gives me <a href="https://www.wb1.com">Pie</a> <a href="https://www.wb2.com">Banana</a> <a href="https://www.wb3.com">Apple</a> <a href="https://www.wb4.com">Source</a>
, which starts from the first <a href= token, instead of the one nearest to the first occurrence of Source. I.e., I want to restrict <a href= to match the last one before the first occurrence of Source. I'm using regex101 for my test. Thanks in advance!  |

| Delta tables in Databricks and into Power BI Posted: 12 Aug 2021 07:49 AM PDT I am connecting to a delta table in Azure gen 2 data lake by mounting in Databricks and creating a table ('using delta'). I am then connecting to this in Power BI using the Databricks connector. Firstly, I am unclear as to the relationship between the data lake and the Spark table in Databricks. Is it correct that the Spark table retrieves the latest snapshot from the data lake (delta lake) every time it is itself queried? Is it also the case that it is not possible to effect changes in the data lake via operations on the Spark table? Secondly, what is the best way to reduce the columns in the Spark table (ideally before it is read into Power BI)? I have tried creating the Spark table with specified subset of columns but get a cannot change schema error. Instead I can create another Spark table that selects from the first Spark table, but this seems pretty inefficient and (I think) will need to be recreated frequently in line with the refresh schedule of the Power BI report. I don't know if it's possible to have a Spark delta table that references another Spark Delta table so that the former is also always the latest snapshot when queried? As you can tell, my understanding of this is limited (as is the documentation!) but any pointers very much appreciated. Thanks in advance and for reading!  |
| How to avoid VLA and malloc when using VULKAN VkEnum-foo-bar function in C language? Posted: 12 Aug 2021 07:49 AM PDT Vulkan programming in C language seems unavoidable to use either malloc or VLA, Look at the following example: uint32_t physicalDeviceNumber = 0; vkEnumeratePhysicalDevices(*instance, &physicalDeviceNumber, NULL); VkPhysicalDevice physicalDevice[physicalDeviceNumber]; vkEnumeratePhysicalDevices(*instance, &physicalDeviceNumber, physicalDevice);
This code simply enumerate physical devices, since I don't know the exact number of GPUs, I call vkEnumeratePhysicalDevices to get the number. and then call it again to actually initialize them. On the second function call, the third argument, VkPhysicalDevice *pPhysicalDevices must be a defined array. Its length must equals to the number of GPUs, or the physical device initialization will be incomplete. See specification here. Here comes the problem, the code above use a DANGEROUS feature in C language, called VLA, or "variable-length-array". This feature allows to create a memory chunk on stack with the size of runtime-generated number. They should definitely be avoided. This blog tells us why. Another solution was to use malloc to solve this, I changed the code a bit: uint32_t physicalDeviceNumber = 0; vkEnumeratePhysicalDevices(*instance, &physicalDeviceNumber, NULL); VkPhysicalDevice *physicalDevice = (VkPhysicalDevice *)malloc(physicalDeviceNumber * sizeof(VkPhysicalDevice)); vkEnumeratePhysicalDevices(*instance, &physicalDeviceNumber, physicalDevice);
And this one corrupt the program, of course. Type VkPhysicalDevice is actually a pointer, its real type is struct VkPhysicalDevice_T *, it points to a big chunk of memory which size is unknown. Also, using malloc is considered a BAD habit in vulkan programming. See discussion here. So I was confused. This simple function cannot be safely used to initialize my GPU unless I know how much GPU my computer has. I'm not an expert in C, but I think there should be safer solution than those codes. If you know how, please provide plain C code and explain why. ps: C++ code is NOT what I want, I know std::vector can solve this, but I'm not gonna use C++.  |
| Stroustroup: free(): double free detected in tcache 2 when implementing vector::reserve() Posted: 12 Aug 2021 07:49 AM PDT The code given in Bjarne Stroustrup - Programming Chapter 19.5.6 "RAII for vector" doesn't work when calling push_back() then reserve().

With debugging I see that after calling swap() inside reserve() the variable b.elem[0] has <error: Cannot access memory at address 0x55555556d> The uninitialized_copy is written wrong in the book so maybe there's something else missing?

| Calculate maximum length of consecutive values in row over a set number Posted: 12 Aug 2021 07:48 AM PDT I have a random 10x10 DF (in reality its a few million rows): df <- replicate(10, sample(0:5, 10, rep=T))
I need to calculate a column on at end of my df that is the a count of the maximum length of consecutive values equal or over a set number e.g. 3 or more. Therefore, a single row that contained the values: 2,4,3,3,4,5,1,0,5,1 would return a value of 5, as the set of values 4,3,3,4,5 are all 3 or more and are consecutive. while a 5 does occur again in the row which is above 3 its consecutive occurrence is less than 5 consecutives numbers over 3 earlier in the row. Any help appreciated.  |

| Postgres grouping by range Posted: 12 Aug 2021 07:49 AM PDT I have data looking like this  What I am trying to achieve is data for historgram that would count values into specific ranges. For category A value range 1-100 and for category B value range 0-125 where value for category C = 5. The problem I have that is data in multiplerows and I need to filter first on C and then count values into ranges to display histogram. To get counts lets say per 10 seconds looking like this  Code to generate data: CREATE TEMP TABLE sample ( ts timestamp ,category varchar(2) , val int) insert into sample values (to_timestamp('01.01.2018 08:00:01', 'dd-mm-yyyy hh24:mi:ss'), 'A', 12) (to_timestamp('01.01.2018 08:00:02', 'dd-mm-yyyy hh24:mi:ss'), 'A', 44), (to_timestamp('01.01.2018 08:00:03', 'dd-mm-yyyy hh24:mi:ss'), 'C', 1), (to_timestamp('01.01.2018 08:00:04', 'dd-mm-yyyy hh24:mi:ss'), 'B', 24), (to_timestamp('01.01.2018 08:00:05', 'dd-mm-yyyy hh24:mi:ss'), 'B', 111), (to_timestamp('01.01.2018 08:00:06', 'dd-mm-yyyy hh24:mi:ss'), 'C', 5), (to_timestamp('01.01.2018 08:00:07', 'dd-mm-yyyy hh24:mi:ss'), 'A', 145)

| Azure app uploads from VSCode without linking static sources Posted: 12 Aug 2021 07:48 AM PDT I have an incredibly basic node.js server test app running on port 3000 in VSCode. The server appears to work via node on localhost or deployed to Azure, and hosts an index.html file. I have clients happy to talk to it. /* Server.js */ const express = require('express'); const app = express(); app.use(express.json()); app.get("/", function(request, response){ response.sendFile(__dirname + "/index.html"); }); app.post("/", function(request, result){ console.log(request.body["itema"] + " " + request.body["itemb"]); result.send("Pong!!"); }); app.listen(3000, function(){ console.log("Server started on port 3000"); });
<!-- Index.html --> <!DOCTYPE html> <html> <head> <title>Simple App</title> <link rel="stylesheet" href="style.css" type="text/css"/> </head> <body> <h1>Test!</h1> </body> </html>
/*style.css*/ h1 { color: tomato; }
Azure Configuration Settings
The index.html links to a css file which doesn't appear to be linked when deployed. I've tried deploying the app to azurewebsites.net through VSCode, however I'm seeing the same results. Only index.html is present in the sources view. I get an error claiming it can't render the source it didn't find. "Refused to apply style from https://<appname>.azurewebsites.net/style.css because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled."
If I view the advanced page (.scm.azurewebsites.net), again I can see only index.html. Index only But .scm.azurewebsites.net/wwwroot/ shows me the css file has been uploaded correctly. Index and linked sources I'm convinced it'll be a simple solution to someone and that the PATH variables will need to be set...somehow... but I've hit a brick wall and my Google-Fu has finally been exhausted. Thanks!  |
| How to pass variable inside JMESpath query? Posted: 12 Aug 2021 07:49 AM PDT I am trying to pass an environment variable inside a JMESpath query for an az cli command. Currently the problem is when I am passing the variable at standalone, I am able to get the result as expected but when I using the same command inside a while or for loop, the value is passing as null. Kindly help me on this and appreciate your effort. My script is as follows: jq -c '.[]' 2data.json | while read i do echo "value of i is $i" az postgres server firewall-rule show --ids $firewallName --query "[name == '$i'].{name:name}" done
Output: value of i is "secondrule" { "name": null } value of i is "newRule" { "name": null }
2data.json file contains [ "secondrule", "newRule" ]
Manual execution of az command: data="secondrule" az postgres server firewall-rule show --ids $firewallName --query "[?name == '$data'].{name:name}"
Output of manual execution: (expected) [ { "name": "secondrule" } ]
How I can resolve this and pass the input as variable and get the desired output?  |
| Trying to sort a column that got Multiple Strings (with some restrictions from my Employer) Posted: 12 Aug 2021 07:49 AM PDT I am having some Problems getting a table column sorted the way the employer wants me to. First i used If cases and "data-order" values to sort this column, but i was told i am not supposed to use hardcoded numbers because of possible "big number problems" or things like that. Now i am looking to get another solution but i seem to be stuck: It's a table with 5 Columns, three of those columns got a pair of two Database Strings in them. Columns are: "Type" | "Worklist" | "Task Name/ Task Description" | "After Running hours/ Interval" | "Next due at date / in Running hours" Now i am supposed to make the "After Running hours/ Interval" column sortable and the result should show first: every entry that actually got a "After Running hours" entry, ascending and the rest should be sorted by interval lenght (Intervals can be x day(s), x week(s), x month(s), x year(s) and both entrys (Interval and Running hours) might be empty and those cases should be at the bottom. Currently the code as shown below sorts After Running hours correctly but after that it goes 1 month(s) -> 1 week(s) -> 1 year(s) -> 2month(s) and so on. I was hoping anyone could give me a hint on how to fix that, maybe a hidden input with{{}} which would bring days/weeks/month/year into the right order. @if($task->worklistTask->running_hours) {{$task->worklistTask->running_hours . " h"}} <br> @if($task->worklistTask->interval && $task->worklistTask->intervalunit) {{ $task->worklistTask->interval }} {{ $task->worklistTask->intervalunit->name }} @else {{"-"}} @endif @elseif($task->worklistTask->interval && $task->worklistTask->intervalunit && ($task->worklistTask->intervalunit->name == 'day(s)')) {{"-"}} <br> {{ $task->worklistTask->interval }} {{ $task->worklistTask->intervalunit->name }} @elseif($task->worklistTask->interval && $task->worklistTask->intervalunit && ($task->worklistTask->intervalunit->name == 'week(s)')) {{"-"}} <br> {{ $task->worklistTask->interval }} {{ $task->worklistTask->intervalunit->name }} @elseif($task->worklistTask->interval && $task->worklistTask->intervalunit && ($task->worklistTask->intervalunit->name == 'month(s)')) {{"-"}} <br> {{ $task->worklistTask->interval }} {{ $task->worklistTask->intervalunit->name }} @elseif($task->worklistTask->interval && $task->worklistTask->intervalunit && ($task->worklistTask->intervalunit->name == 'year(s)')) {{"-"}} <br> {{ $task->worklistTask->interval }} {{ $task->worklistTask->intervalunit->name }} @else {{"-"}} <br> {{"-"}} @endif </td> Example Table | Type | Worklist | TaskN./ TaskDes.| ARH <br> Int. | Nextdue/ iRHs| |:------ |:--------:| :--------------:|:-----------------:|-------------:| | Default | WLName1 | Task1/Taskstuff |100h <br> 1 year(s)| -/- | | Default | WLName3 | Task4/Taskstuff |150h <br> - | -/- | | critical| WLName3 | Task5/Taskstuff |200h <br> 1 week(s)| -/- | | Default | WLName1 | Task2/Taskstuff |- <br> 1 month(s) | -/- | | Solas | WLName2 | Task3/Taskstuff |- <br> 1 week(s) | -/- | | Default | WLName4 | Task6/Taskstuff |- <br> 2 month(s) | -/- | We use the js-table plugin. Type and Worklist make no problems at all (Press the header and it gets sorted properly) "TaskN./TaskDes." only sorts the taskNames alphabetically but that seems to be no issue for the customer for now. Next due can't be sorted by "inRunningHours" but thats also not a problem for now. Sorting the ARH/Int. ("After Running hours" / "Interval") Column at the moment sorts The Running hours, ascending, correctly. After that things get messed up. He still sorts the "rest of the string" alphabetically (everything without a running hours value will get a "-" but i would need them to be sorted after interval length. The Previous version was unwanted and now i am looking for a new solution. Previous solution: ```<td data-order="@if($task->worklistTask->running_hours){{ $task->worklistTask->running_hours }} @elseif (!empty($task->worklistTask->interval) && $task->worklistTask->intervalunit->name == 'day(s)') {{50000 + $task->worklistTask->interval * 1}} @elseif (!empty($task->worklistTask->interval) && $task->worklistTask->intervalunit->name == 'week(s)') {{50000 + $task->worklistTask->interval * 7}} @elseif (!empty($task->worklistTask->interval) && $task->worklistTask->intervalunit->name == 'month(s)') {{50000 + $task->worklistTask->interval * 30}} @elseif (!empty($task->worklistTask->interval) && $task->worklistTask->intervalunit->name == 'year(s)') {{50000 + $task->worklistTask->interval * 365}} @else 999999 @endif">

| loop over aws provider to create ressources in every aws account Posted: 12 Aug 2021 07:49 AM PDT I have a list of objects in Terraform called users and the structure is the following: variable "accounts" { type = list(object({ id = string #used in assume_role email = string is_enabled = bool })) }
What I am trying to achieve now is to create a simple S3 bucket in each of those AWS accounts (if the is_enabled is true). I was able to do it for a single account but I am not sure if there is a way to loop over a provider?

| How to make mouse scroll work in AWS Workspace Posted: 12 Aug 2021 07:49 AM PDT I am using AWS Workspace with Linux for some work. And using Windows Client to connect to it.
Everything seems to be working fine except I cannot use mouse scroll in the workspace(not working in firefox/terminal/any-window). (scroll is working fine on the machine where the client is running) Left-click and right-click both are working fine. I tried to find it on AWS forums and SO too, but couldn't find anything related to this. If you try to search the same on Google, there is one similar thread - but it's related to mouse with some extra buttons. Scrolling seems to be a basic functionality that should be provided. Any help would be appreciated. Thanks.  |
