| Run python function from command-line - invalid syntax due to full file path Posted: 27 Aug 2021 08:01 AM PDT I try to run a python function from command-line: H:\myfolder\python.exe -c "from P:\myproject\myscript import myfct; myfct(1,2)"
An error occurs with this message: P:\myproject\myscript ... ^ SyntaxError: invalid syntax
It works fine without the folder path: H:\myfolder\python.exe -c "from myscript import myfct; myfct(1,2)"
The script should preferably run from other directories as well. Double backslash does not solve the problem as also stated here. As far as I can judge, it's not a problem of directory change. How do I have to write the command string which contains the full file path? The directory P: is a mapped network directoy. Is this a problem? I'm using Python 3.9.5 on Windows 10 Pro.  |
| How to avoid using a package in Angular Universal Posted: 27 Aug 2021 08:01 AM PDT I have been using Angular Universal SSR (Angular 12) with Express and @agm/core (Google Maps). I get this error: ERROR ReferenceError: window is not defined at WindowRef.getNativeWindow
this happens because @agm/core is trying to use window and this is not defined in server side. So my question is, how can i disable this package in server side for not get this type of errors?. For the integration you have to import @agm/core at app.module like this: AgmCoreModule.forRoot({ apiKey: ['YOUR_API_KEY_HERE'], })
And then you will be able to use the agm-map component.  |

| Am I using the useEffect hook correctly to try and fetch data? Posted: 27 Aug 2021 08:01 AM PDT I am having some issues with my React code when trying to use the useEffect hook to fetch data from an API. This is my boiled down code: const App = () => { const [ data, setData ] = useState([]); const [ loading, setLoading ] = useState(false); useEffect(() => { const loadData = async () => { try { setLoading(true); const response = await fetch(`htts://localhost/api/`); const json = await response.json(); console.log(json); setData(json); setLoading(false); } catch (error) { console.log("error: " + error); } } loadData(); }, []); }
I am running into issues that when I render the html it's giving me errors that I am unable to map to some of the data that I am setting from my API. I was thinking that setting the data variable would give me the ability to spit out data in the template and the various object key names like: { data.keyname.map((item, index) => { return ( <option key={ index } value={ item.displayName } > { item.displayName } </option> ); }) }
Am I overlooking something here? It appears that my data isn't loading so the render code can't loop through any of the data it needs to in order to render the app.  |

| React Native Expo-Location returns Location service unavailable during initial useEffect Posted: 27 Aug 2021 08:01 AM PDT Main Problem: I am using expo-location in my Android app in order to find the gps coordinates of the user. I have read and used the sample code provided in the expo documentation. My main problem is that, Location.getCurrentPositionAsync({}) returns Location provider is unavailable. Make sure that location services are enabled. This is my code below: useEffect(() => { (async () => { let { status } = await Location.requestForegroundPermissionsAsync(); if (status !== 'granted') { setErrorMsg('Permission to access location was denied'); return; } let location = await Location.getCurrentPositionAsync({}); console.log(location); })(); }, []);
Status returns granted but getCurrentPositionAsync({}) returns an error. I implemented a janky solution by using try-catch blocks and running getCurrentPositionAsync({}) again in the catch block, which seems to work. This is my code below: useEffect(() => { (async () => { let { status } = await Location.requestForegroundPermissionsAsync(); if (status !== 'granted') { setErrorMsg('Permission to access location was denied'); return; } try { var location = await Location.getCurrentPositionAsync({}); } catch { location = await Location.getCurrentPositionAsync({}); } console.log(location); })(); }, []);

| Missing Value Error although "na.action" was set to "na.roughfix" Posted: 27 Aug 2021 08:01 AM PDT I would like to create a Random Forest model with caret. Since there are missing values in the training set, I was looking for possible solutions and came across the option "na.roughfix" from the package "randomForest". If the library randomForest is loaded, this option can be used as argument for the parameter "na.action" within the train function of caret. Inside the train function I use a 5-fold CV and tune for the best ROC value. I do this to ensure comparability between other models. The method I've chosen for the Random Forest is "ranger". But now something strange happens: When I trigger the train function, the calculation is started, but for example the following error message appears: model fit failed for Fold5: mtry= 7, splitrule=gini, min.node.size= 5 Error : Missing data in columns: ... The "..." stands for the columns in which the missing values occur. Moreover, this error message always occurs, no matter for which fold or value for mtry. I am well aware that there are missing values in these columns ... that's why I use na.roughfix. I also remove the NZVs, but that doesn't help either. I would be very happy about an explanation or even a solution! Many greetings Edit.: I've seen now that, if I want to choose the "na.action" arugment in the train function, it does not appear automatically, which it usually does. It seems that it's somehow lost ... maybe this is the reason, why caret does not use the na.roughfix ... Edit. 2: I guess that this is one part of the problem. train behaves always differently, depending on the previous arguments. In my train function I use a recipe from the recipe package to remove the NZVs. As soon as I remove the recipe, the na.action argument becomes available again. However, now the preProcess argument vanished, meaning I cannot remove the NZVs anymore. This is really a mess ...  |

| Can I use memory after pointer deinitialization? Posted: 27 Aug 2021 08:01 AM PDT Can I use memory after pointer deinitialization? e.g. let q = UnsafeMutablePointer<Float>.allocate(capacity: 1) q.pointee = 123.125 let bq = UnsafeRawBufferPointer(start: q.deinitialize(count: 1), count: 4) // (*) for i in bq.reversed() { print(String(i, radix: 16), terminator: " ") } q.deallocate() print()
It's my core solution of this task: https://pl.spoj.com/problems/PP0504D/ Problem in the task is simple: Write a function which show binary representation of Float value. float2binary(123.125) prints 42 f6 40 0 But that is not the crux of the problem.
I'm not deeply in pointers. My doubt is: May I use memory after deinitialization which is points by another pointer (this memory is NOT deallocated)? What does deinitialization really mean? let p = UnsafeMutablePointer<Int>.allocate(capacity: 1) p.initialize(to: 7) print(p.pointee) p.initialize(to: 9) p.deinitialize(count: 1) // something may crash the memory in this place? print(p.pointee) p.deallocate()
Anyone can show me the code that causes the crash after deinicialize(count:) ?  |

The logs show that the variables before the function were all initialized, which means the custom function is working. I also tested it an hour ago, and my custom function worked. 
I also have other script files with functions but the only global varialbe is from a Spreadsheet.getActiveSpreadsheet();

To add: onOpen() function seems to be running forever too... 
Code below for onOpen trigger function: function onAppOpen() { const ui = SpreadsheetApp.getUi(); ui.createMenu('⚙️ SLI Tools') .addSubMenu (ui.createMenu('Tracker') .addItem('↺ Refresh data', 'refreshDataToTrackerAlert') .addItem('⇧ Upload changes', 'uploadChangesAlert') .addItem('⇧ Upload ALL rows', 'uploadAllChangesAlert') .addSeparator() .addItem('✕ Clear data', 'clearDataAlert') ) .addSubMenu(ui.createMenu('Billing') .addItem('⇩ Export to PDF', 'printToPdf') .addSeparator() .addItem('🖌 Format tables', 'formatDataTable') ) .addSubMenu(ui.createMenu('Uploader') .addItem('⇧ Upload new JO', 'uploadDataToSourceAlert') .addSeparator() .addItem('✕ Clear data', 'clearUploaderDataAlert') ) .addSeparator() .addSubMenu(ui.createMenu('Data') .addItem('↺ Refresh background query', 'refreshQueryAlert') ) .addToUi(); }
The sheet itself also seems to reload forever. 
This shows that the file is connected to the internet and not disconnected. 
Update: It seems to be working again. Could it be the GAS servers malfunctioning? Update 2: I haven't changed the code for the function in this test. The last 2 runs had an average of 19 seconds runtime. After some minutes, the script gets stuck again. 
Chrome also isnt at full CPU although it is expected to hog the memory with 4 tabs running.

| How does scanf know if it should scan a new value? Posted: 27 Aug 2021 08:00 AM PDT I'm studying about how scanf works. After scanned other type variable, char variable stores a white-space('\n') by getchar() or scanf("%c"). To prevent this, they should clear buffer. And I did it with rewind(stdin) though stdin is rewinded previous input value is keeping in buffer. and I can do something with the previous value normally.(nothing runtime errors) but if I try scanf again, scanf will scan a new value even there is a normal value in buffer. how does scanf determine if it should scan a new value? I found this mechanism with below code. #include <stdio.h> #define p stdin int main() { int x; char ch; void* A, * B, * C, * D, * E; A = p->_Placeholder; printf("A : %p\n", A);//first time, it shows 0000 scanf_s("%d", &x); B = p->_Placeholder; printf("B : %p\n", B);//after scanned something, I think it's begin point of buffer which is assigned for this process rewind(stdin);//rewind _Placeholder C = p->_Placeholder; printf("C : %p\n", C);//it outputs the same value as B - length of x D = p->_Placeholder; printf("D : %c\n", ((char*)D)[0]);//the previous input value is printed successfully without runtime error. it means buffer is not be cleared by scanf scanf_s("%c", &ch, 1);//BUT scanf knows the _Placeholder is not pointing new input value, so it will scan a new value from console. How?? E = p->_Placeholder; printf("E : %p\n", E); printf("ch : %c\n", ch); }

| Extracting data based off of values in a column - Excel Posted: 27 Aug 2021 08:01 AM PDT How would I set up a sheet that extracts data from a table with selected rows based off of the values from a column.

I have a column simply listing Food Items, "Chip 1","Chip3","Chip4". I would like to have the second table show information for only Chips 1,3,4 on another sheet. This criteria column will likely change as well so the final table must reflect that each time it changes. Thanks! Edit Criteria Table | Food Item | | Chip 1 | | Chip 3 | | Chip 4 | Original table | Food Item | Caloric Count | Percentage of Protein | Percentage of Fat | | Chip 1 | 111 | 1% | 2% | | Chip 2 | 500 | 3% | 2.5% | | Chip 3 | 40 | .4% | .5% | | Chip 4 | 50 | .5% | .5% | | Chip 5 | 372 | 3% | 5% | Table 2 | Food Item | Caloric Count | Percentage of Protein | Percentage of Fat | | Chip 1 | 111 | 1% | 2% | | Chip 3 | 40 | .4% | .5% | | Chip 4 | 50 | .5% | .5% | EDIT I went searching for a solution. Lookup value is in table 'Criteria' row J15 and would match one of the values in 'Data' Column A, the table where rows to be extracted from. I still get an error where Excel thinks I am mistakenly trying to type a formula. I've been trying to work on this for hours, thanks for all the help thus far. Link for reference: https://www.reddit.com/r/excel/comments/8etavq/return_all_rows_that_match_a_certain_criteria_on/dxxyyta/ =INDEX('Data'!A1:A124,SMALL(IF('Data'!$A$5:$A$124='Criteria'!$J$15,ROW('Data'$A$5:$A$124)-ROW(INDEX('Data'$A$5:$A$124,1,1))+1),row()-2))  |
| Livewire: Trying to get property 'id' of non-object generating code from foreach Posted: 27 Aug 2021 08:01 AM PDT I'm new to Livewire and I encounter an error which origin I don't know. I made a page with a list of simple objects (id, name, and description). The page has a list of all the items available and I want to click on that list to view the item properties or a button to delete the item. That list is made with this foreach: @foreach($listaTareas as $t) <div class="data col-12" wire:click="show({{ $t->id }})"> <label>{{ $t->nombre }}</label> <label class="hint">ID: {{ $t->id }}</label> <button type="button" class="btn btn-danger" wire:click="delete({{ $t->id }})"><i class="fas fa-trash"></i></button> </div> @endforeach
Which renders perfectly List rendered However, clicking on any div or in the trash can button results in error Trying to get property 'id' of non-object pointing at <div class="data col-12" wire:click="show({{ $t->id }})">. If I delete the show and delete attributes (and modify the livewire component consequentely) leaving something like this: @foreach($listaTareas as $t) <div class="data col-12" wire:click="show"> <label>{{ $t->nombre }}</label> <label class="hint">ID: {{ $t->id }}</label> <button type="button" class="btn btn-danger" wire:click="delete"><i class="fas fa-trash"></i></button> </div> @endforeach
I still get the same error, this time pointing at <label>{{ $t->nombre }}</label>, so crearly there is something obvious I'm doing incredibly wrong. I have heard about the wire:key attribute but I don't know how to use it for my purposes. All the code: Livewire view <div class="row align-items-start"> <!-- Sección de la lista de tareas --> <div class="col-5"> <div id="listado" class="contenedor-data"> <div id="add"> <label for="btnadd" class="info">Puedes añadir una tarea con este botón...</label> <button id="btnadd" type="button" class="btn btn-primary" wire:click="create">Añadir</button> </div> @foreach($listaTareas as $t) <div class="data col-12" wire:click="show({{ $t->id }})"> <label>{{ $t->nombre }}</label> <label class="hint">ID: {{ $t->id }}</label> <button type="button" class="btn btn-danger" wire:click="delete({{ $t->id }})"><i class="fas fa-trash"></i></button> </div> @endforeach <div id="coletilla"> <a class="btn btn-primary" href="#add" role="button"> <i class="fas fa-angle-up"></i> </a> </div> </div> </div> <!-- Sección del desglose de tareas --> <div class="col-7"> <div id="desglose" class="contenedor-data"> <div class="form-group"> <label for="nombre">Tarea:</label> <label id="id_tarea" class="hint">{{ $tid }}</label> <input type="text" class="form-control" id="nombre" placeholder="Nombre de la tarea" wire:model="nombre"> </div> <div class="form-group"> <label for="descripcion">Descripción</label> <textarea class="form-control" id="descripcion" aria-describedby="hint" wire:model="descripcion"></textarea> <small id="hint" class="form-text text-muted">Aquí va la descripción de la tarea.</small> </div> <div> <button id="btnadd" type="button" class="btn btn-success" wire:click="create">Añadir</button> <button id="btnmod" type="button" class="btn btn-primary">Modificar</button> <button id="btndel" type="button" class="btn btn-danger">Eliminar</button> </div> </div> </div> </div>

| Mac with two Python version (2.7 and 3.9) but pointing to 2.7 [closed] Posted: 27 Aug 2021 08:00 AM PDT I'm trying to install AWS cli (https://docs.aws.amazon.com/cli/latest/userguide/install-macos.html) in my mac (Big Sur 11.5.2). When I try I got an error saying python 2.7 is old and I need at least python 3.6. I found that I have two python versions installed: which python => /usr/bin/python python -V => Python 2.7.16 which python3 => /usr/local/bin/python3 python3 --version => Python 3.9.6
I have two options: 1- Uninstall python 2.7. But it seems that it is a bad idea (How to uninstall Python 2.7 on a Mac OS X 10.6.4?) 2- Keep both python versions, but how do I make AWS use python 3.9.6 instead of python 2.7?  |

| Dynamically add json object into array with jq Posted: 27 Aug 2021 08:01 AM PDT Below is the template of my employee.json file { "orgConfig": { "departments": [] } }
where departments will have array of departments like below { "name" : "physics", "id" : "1234", "head" : "abcd" }
similarly { "name" : "chemistry", "id" : "3421", "head" : "xyz" }
so the final array structure i want to construct is as below { "orgConfig": { "departments": [ { "name" : "physics", "id" : "1234", "head" : "abcd" }, { "name" : "chemistry", "id" : "3421", "head" : "xyz" }, { "name" : "Maths", "id" : "4634", "head" : "jklm" } ] } }
Below is the code where i am adding the json elements to an departments array dynamically #!/bin/bash source department.properties # will have departments=physiscs,chemistry,Maths,computers .. etc IFS=',' read -ra NAMES <<< "$departmentsToImport" position=0 for i in "${NAMES[@]}"; do #./jsonfiles will chemistry.json, physics.json, Maths.json etc value=`cat ./jsonfiles/$i.json` if [ $position -eq 0 ] then cat employee.json | jq --arg value "$value" '.orgConfig.departments[0] |= .+ $value' > tmp.json && mv tmp.json employee.json else cat employee.json | jq --arg position "$position" value "$value" '.orgConfig.departments[$position] |= .+ $value' > tmp.json && mv tmp.json employee.json fi ((position++)) rm -rf tmp.json done exit $?
but program throws below error jq: error (at <stdin>:51): Cannot index array with string "1"
But if use direct index instead of variable position then it works fine. cat employee.json | jq --argjson value "$value" '.orgConfig.departments[1] |= .+ $value' > tmp.json && mv tmp.json employee.json
I do not know how many key value maps of departments i have. I cannot hard code the index. Any help to above problem and Dynamically add json object into array? Thanks  |
| Quartz.NET - Call a function after the Job has completed Full Execution Posted: 27 Aug 2021 08:01 AM PDT We are using Quartz.Net to trigger jobs on a schedule in a Windows Service . I have a situation where I have to Trigger a job every 5 minutes from Start DateTime till End DateTime. After the job is completed we need to calculate the Next Start DateTime and Next End DateTime and save to the DB - For this I tried to override the JobListener which has a method: JobWasExecuted public class xPTJobListener : JobListenerSupport { public override string Name { get { return "xPTJobListener"; } } public override void JobWasExecuted(IJobExecutionContext context, JobExecutionException jobException) { var dataMap = context.MergedJobDataMap; var schedule = (MyDTO)dataMap["Schedule"]; using (var logger = new xPTLogger()) { logger.LogMessage(MessageType.Information, string.Format("Inside JobWasExecuted() - [{0}] - ", schedule.Id)); } base.JobWasExecuted(context, jobException); } }
and also the TriggerComplete in the TriggerListener public class xPTTriggerListener : TriggerListenerSupport { public override string Name { get { return "xPTTriggerListener"; } } public override void TriggerComplete(ITrigger trigger, IJobExecutionContext context, SchedulerInstruction triggerInstructionCode) { var dataMap = context.MergedJobDataMap; var schedule = (MyDTO)dataMap["Schedule"]; using (var logger = new xPTLogger()) { logger.LogMessage(MessageType.Information, string.Format("Inside Trigger Complete - [{0}] - ", schedule.Id)); } base.TriggerComplete(trigger, context, triggerInstructionCode); } }
But the problem with above methods is that they are both executed each time the job is called. So if I have a Job which runs from 12:01 AM and ends 12:02 AM every 5 seconds - Both these methods get called 12 times What I need is to call a method only once after the One Job iteration has Ended - (After the Job is executed 12 Times)? How do I do this in Quartz? EDIT Creating the Triggers public static ITrigger GenerateTrigger(RouteMonitorScheduleDTO routeSchedule, double fGmtOffset, xPTLogger logger) { ITrigger trigger = null; switch (routeSchedule.ScheduleInfo.PeriodType) { case PeriodTypeEnum.Once: trigger = TriggerBuilder.Create() .WithIdentity(string.Format("trigger_{0}", routeSchedule.RouteScheduleId), DefaultGroup) .StartAt(routeSchedule.DepartureDateTime) .WithSimpleSchedule(s => s.WithIntervalInMinutes(5)) .EndAt(routeSchedule.ArrivalDateTime.AddMinutes(5)) .Build(); break; case PeriodTypeEnum.Daily: case PeriodTypeEnum.WeekDays: case PeriodTypeEnum.Weekly: case PeriodTypeEnum.Monthly: var schedule = routeSchedule.ScheduleInfo; var cronExpresion = xPTCronBuilder.GenerateCronExpression( schedule.PeriodType, schedule.ScheduleStringValue, fGmtOffset, routeSchedule.DepartureDateTime, routeSchedule.ArrivalDateTime.AddMinutes(5), 5); trigger = TriggerBuilder.Create() .WithIdentity(string.Format("trigger_{0}", routeSchedule.RouteScheduleId), DefaultGroup) .WithCronSchedule(cronExpresion) .Build(); break; } return trigger; }
EDIT Trigger with Cron: trigger = TriggerBuilder.Create() .WithIdentity(string.Format("trigger_{0}", 1), "Group1") .WithCronSchedule("0 0-45/5 7-7 ? * TUE,WED *").Build();
As you can see from above cron expression it will run from 7 AM to 7:45 AM every 5 minutes every Tuesday and Wednesday. So 1 iteration is 7AM to 7:45 AM on Tuesday, the Next is 7 AM to 7:45 on Wednesday. I need to call a function after each Iteration has completed. So let's say that when the Last Trigger is fired for 7:45 AM on Tuesday - I need to call the function.  |
| Hierarchical package structure in Eclipse Posted: 27 Aug 2021 08:02 AM PDT I am working with eclipse on an android project. I want to have packages inside of packages inside of packages and so on... The problem is I can only have 1 type of subpackage. (I want more depth) At the moment my project looks like this: - com.company.main - subpackone + class1 + class2 + class3 - subpacktwo + class4 - subpackthree + class5
But what I want is something like this: - com.company.main - subpackone + class1 + class2 + class3 - subpacktwo + class4 - subpackthree + class5
When I try to create more packages inside of subpackages it just changes the name of the already existing subpackage. I already set the Package Presentation to Hierarchical in eclipse.  |
| Fit cell width to content Posted: 27 Aug 2021 08:00 AM PDT Given the following markup, how could I use CSS to force one cell (all cells in column) to fit to the width of the content within it rather than stretch (which is the default behaviour)? <style type="text/css"> td.block { border: 1px solid black; } </style> <table style="width: 100%;"> <tr> <td class="block">this should stretch</td> <td class="block">this should stretch</td> <td class="block">this should be the content width</td> </tr> </table>
EDIT: I realize I could hard code the width, but I'd rather not do that, as the content which will go in that column is dynamic. Looking at the image below, the first image is what the markup produces. The second image is what I want.
