| Cleanest way to wrap a static class in a non-static object (refactoring to allow mocking) Posted: 02 Nov 2021 08:16 AM PDT I'm working with Java and Kotlin, and the codebase has some legacy static classes which really should be objects, but are too deeply tangled to make them non-static now. I want to be able to cleanly test (using mocks of these static dependencies) some (non-static) classes that depend on these static classes, so I want to wrap the static classes in non-static dummy wrappers, i.e. instantiatable objects whose instance methods just call their static counterparts. I'll then mock these wrappers in unit tests (I don't want to just use static mocking). The manual way to do this is for each static class Foo with method public static void bar(), define a new class FooWrapper with method public void bar() that just calls Foo.bar(), instantiate a FooWrapper at the top of my class, and switch all the current calls to Foo.bar() to instead call fooWrapperInstance.bar(). The above works fine but involves a lot of boring Wrapper classes that do nothing but pass calls. Is there some syntactic sugar (either Java or Kotlin is fine, but it has to work with Java) that will create, or at least shorten, these wrapper classes for me? I'm familiar with Guava's ForwardingObject but it seems to only work when the underlying logic is in an instance already, which mine is not.  |

| How to obtain "jagged" edges on silhouette images? Posted: 02 Nov 2021 08:15 AM PDT I am trying to replicate a paper in which silhouette images are transformed in order to have jagged edge:  Unfortunately, the paper doesn't provide any detail about how these were generated. Do you guys have any idea how could I go around it? Doesn't need to be exactly the same, the important bit is to mess up with the local features of each object. Ideally I would like to do it in python with OpenCV/PIL/PyTorch, but anything is ok really. Thanks.  |

| Downloading s3 bucket to local directory but files not copying? Posted: 02 Nov 2021 08:15 AM PDT There are many, many examples of how to download a directory of files from an s3 bucket to a local directory. aws s3 cp s3://<bucket>/<directory> /<path>/<to>/<local>/ --recursive
However, I run this command from my AWS CLI that I've connected to and see confirmation in the terminal like: download: s3://mybucket/myfolder/data1.json to /my/local/dir/data1.json download: s3://mybucket/myfolder/data2.json to /my/local/dir/data2.json download: s3://mybucket/myfolder/data3.json to /my/local/dir/data3.json ...
But then I check /my/local/dir for the files, and my directory is empty. I've tried using the sync command instead, I've tried copying just a single file - nothing seems to work right now. In the past I did successfully run this command and downloaded the files as expected. Why are my files not being copied now, despite seeing no errors?  |

| in batch script compare extension with file extension and move Posted: 02 Nov 2021 08:16 AM PDT How to write a batch script according to the following instructions: - Take only folder name as input.

- Loop through each file, and extract its extension.
- Check if a directory exists with that extension, if not, create it.
- Move the file to its respective extension named folder.

| How to split a date column into day/month/year columns using python Posted: 02 Nov 2021 08:15 AM PDT I have a csv file with just one column 'date' formatted as integer: | date | | 20181231 | | 20190107 | | 20210329 | | ... | The solution would be to split the integer into different columns to represent day, month, year and quarter, like: | date | day | month | year | quarter | | 20181231 | 31 | 12 | 2018 | 4 | | 20190107 | 07 | 01 | 2019 | 1 | | 20210329 | 29 | 03 | 2021 | 2 | | ... | ... | ... | ... | ... | I would appreciate every kind of solution but I should resolve it using a python program without using pandas library.

| How to edit each line of file and write to file after each edit Posted: 02 Nov 2021 08:16 AM PDT I have a file that is very large. I need to rearrange something in the file but the file is too large to load into memory. I was thinking of ways to achieve this goal and what I came up with was just editing the file line by line. So what I need to do is read the file, remove certain columns, and then write the file. As I mentioned before, the file is very large so I need to write the file as the script runs. I will give an example data set and the code that I am using Here is an example dataset {'CHROM': {0: 'chr1', 1: 'chr1'}, 'POS': {0: 10397, 1: 12719}, 'ID': {0: '.', 1: '.'}, 'REF': {0: 'CCCCTAA', 1: 'G'}, 'ALT': {0: 'C', 1: 'C'}, 'QUAL': {0: 943.64, 1: 255.34}, 'FILTER': {0: 'VQSRTrancheINDEL99.00to100.00', 1: 'VQSRTrancheSNP99.80to100.00'}, 'INFO': {0: 'AC=1;AF=0.5;AN=2;BaseQRankSum=1.07;ClippingRankSum=-0.322;DP=11;ExcessHet=0.2139;FS=1.056;InbreedingCoeff=0.1828;MQ=27.81;MQ0=0;MQRankSum=1.59;NEGATIVE_TRAIN_SITE;QD=25.5;ReadPosRankSum=0.572;SOR=0.922;VQSLOD=-2.735;culprit=DP', 1: 'AC=1;AF=0.5;AN=2;BaseQRankSum=-0.922;ClippingRankSum=-0.198;DP=7;ExcessHet=0.0067;FS=0;InbreedingCoeff=0.4331;MQ=24.5;MQ0=0;MQRankSum=-1.495;QD=17.02;ReadPosRankSum=1.5;SOR=3.126;VQSLOD=-28.96;culprit=MQ'}, 'FORMAT': {0: 'GT:AD:DP:GQ:PL', 1: 'GT:AB:AD:DP:GQ:PL'}, 'CGND-HDA-03201': {0: '0/1:5,6:11:99:224,0,156', 1: '0/1:0.29:2,5:7:42:126,0,42'}, 'CGND-HDA-03202': {0: '0/1:5,6:11:99:224,0,156', 1: '0/1:0.29:2,5:7:42:126,0,42'}}
Here is the code that I am using n = 0 for line in open(input, "r+"): li=line.strip() if li.startswith("#"): n = n+1 if not li.startswith("#"): test = li.split("\t") test2 = (f"{test[0]}\t{test[1]}\t{test[9:]}") with open("output.txt","w") as out: out.write(test2, sep='\t')
I have a few problems here the output contain on one single line, the last line that was read. For example, the file contains one line like this chr1 1021791 ['0/1:0.56:22,17:39:99:414,0,623', '0/1:0.56:22,17:39:99:414,0,623']
I don't want the output to have any bracket. I need the output to look more like this chr1 1021791 0/1:0.56:22,17:39:99:414,0,623 0/1:0.56:22,17:39:99:414,0,623
I need the ouput file to be tab delimited Is there a way I can continuously write to a file after each line is edited? The original file does contain #'s that I didn't show here, so the part of the script that ignores lines with #'s is required I know this can easily be done using bash but I am looking for a solution using python.  |
| Failed call to cuInit: CUDA_ERROR_NOT_INITIALIZED: initialization error Posted: 02 Nov 2021 08:16 AM PDT I am trying to run tensorflow with gpu support in a docker on a virtual machine. I have tried lots of online solutions including: none of the solutions work for me, here some steps: I verified that drivers and cuda and cudnn toolkit are installed inside the container using nvidia-smi and nvcc -V: 
Python version is : Python 3.8.10 and tensorflow version is: import tensorflow as tf tf.__version__ '2.6.0'
The error appears with: tf.config.list_physical_devices() 
So the GPU is somehow not visible to the tensorflow. All tensorflow builds return the same error: E tensorflow/stream_executor/cuda/cuda_driver.cc:271] failed call to cuInit: CUDA_ERROR_NOT_INITIALIZED: initialization error
but for example for 1.14 there is an additional comment regarding the CPU type: Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX2 AVX512F FMA
The GPU is a A100 and the CPU is Intel(R) Xeon(R) Gold 6226R. What is going on here? How do I fix this?  |

| Shift with dynamic n (number of position lead / lag by) Posted: 02 Nov 2021 08:16 AM PDT I have the below df: df <- data.table(user = c('a', 'a', 'a', 'b', 'b') , spend = 1:5 , shift_by = c(1,1,2,1,1) ); df user spend shift_by 1: a 1 1 2: a 2 1 3: a 3 2 4: b 4 1 5: b 5 1
and am looking to create a lead lag column only this time the n parameter in data.table's shift function is dynamic and takes df$shiftby as input. My expected result is: df[, spend_shifted := c(NA, 1, 1, NA, 4)]; df user spend shift_by spend_shifted 1: a 1 1 NA 2: a 2 1 1 3: a 3 2 1 4: b 4 1 NA 5: b 5 1 4
However, with the below attempt it gives: df[, spend_shifted := shift(x=spend, n=shift_by, type="lag"), x]; df user spend shift_by spend_shifted 1: a 1 1 NA 2: a 2 1 NA 3: a 3 2 NA 4: b 4 1 NA 5: b 5 1 NA
This is the closest example I could find. However, I need a group by and am after a data.table solution because of speed. Truly look forward to finding any ideas. Thank you  |

| Helm dependency range failure Posted: 02 Nov 2021 08:16 AM PDT Take an umbrella chart, umbrella_chart, with one subchart, sub_chart: umbrella_chart has dependencies defined as follows in it's Chart.yaml: apiVersion: v2 name: umbrella_chart description: A Helm chart for Kubernetes type: application version: 0.1.0 appVersion: 0.1.0 dependencies: - name: sub_chart version: "~0.1.0" repository: "@local-development"
And sub_chart has a Chart.yaml like: apiVersion: v2 name: sub_chart description: A Helm chart for Kubernetes type: application version: 0.1.0 maintainers: - name: Me appVersion: 0.1.0
As part of my CI/CD pipeline, I want to append the Jenkins build number to the sub_chart's version number, before packaging and pushing. This works fine. For build 123 I end up with a version of 0.1.0-123 pushed to local-development. helm search repo --versions --devel NAME CHART VERSION APP VERSION DESCRIPTION local-development/sub_chart 0.1.0-123 0.1.0 A Helm chart for Kubernetes
However, when I run helm dep up umbrella_chart I get the following error: Hang tight while we grab the latest from your chart repositories... ...Successfully got an update from the "local-development" chart repository Update Complete. ⎈Happy Helming!⎈ Error: can't get a valid version for repositories sub_chart. Try changing the version constraint in Chart.yaml
I thought the use of the tilde would allow helm take any chart version >0.1.0 and <0.2.0? Do I need to have a version 0.1.0 of sub_chart in my repo to be able to build umbrella_chart? Will it use the correct 0.1.0-123 version of sub_chart in that instance? Thanks for any help  |
| How to determine the port on which a Windows service is listening? Posted: 02 Nov 2021 08:15 AM PDT I have running a Windows service called my-service. The only input that I know is the service name. I can get the process identifier by using the service name: $id = Get-WmiObject -Class Win32_Service -Filter "name='my-service'" | Select-Object -ExpandProperty ProcessId
To get a list of Listening ports, I can use netstat, but all my custom services have PID 4 which is not equal to the service process identifier of Get-WmiObject cmdlet. 
The goal is to get the port on which the service is listening by using PowerShell or CMD based on the service name or the process identifier and NOT by the image name.  |
| Make string operations on field in mongodb collection (Aggregation & regex) Posted: 02 Nov 2021 08:15 AM PDT I am using a collection in Mongo with a price field with multiple money type : { price: '15 gp' // 15 gold pieces }
or { price: '4 sp' // 0.4 gold pieces }
I'm looking for a way to modify this field before querying the collection. For example doing string modifications to remove the gp/sp and doing math operations to have a correct price in "GP" (1 GP = 10 SP) This would help ordering the collection since mongo can't understand that 10 sp < 2 gp. Is there a way to use Aggregation and regex to do it ?  |

| Using CSVhelper to update a single column into a previously written CSV file . I have the code in Java but can't translate it into C# Posted: 02 Nov 2021 08:15 AM PDT Essentially I have to read and update the CSVfile (only one column) with the current date after the test finishes executing(ie,there are some values written in at the start of the test execution and then I need to update the same file to input another value). I also have a DateTime error which isn't getting resolved no matter what I try. Sample of CSV start of test RunId ProductArea Product Component PageObject Control TimeTakenByLocatorJson Run_645987 R201 BN2018.5 N778 BC1 C143
CSV one column Needs to get updated after test ( TimeTakenByLocatorJson) RunId ProductArea Product Component PageObject Control TimeTakenByLocatorJson Run_645987 R201 BN2018.5 N778 BC1 C143 2021-07-19
I've been trying to update a CSV file using CSVhelper. The code I have is in Java and when I tried translating the same code in C# it doesn't work. This is the code in Java public synchronized void writeEndCSV(String runId) { CSVWriter csvWriter = null; try { String setupCSVLocation = Reporting.getSetupCSVLocation(); CSVReader csvReader = new CSVReader(new FileReader(setupCSVLocation)); List<String[]> records = csvReader.readAll(); for(int i=0;i<records.size();i++) { if(records.get(i)[SETUP_RUNID].equalsIgnoreCase(runId)); { records.get(i)[SETUP_TimeTakenByLocatorJSON] = Reporting.getExecutionEndDate(); } } csvReader.close(); csvWriter = new CSVWriter(new FileWriter(setupCSVLocation)); csvWriter.writeAll(records); csvWriter.flush(); csvWriter.close(); } catch (Exception e) { e.printStackTrace(); } }
This is my code in C# (I'm new to .Net so I'm not sure about many parts) public void writeEnd(string runId) { var records = Enumerable.Empty<LocatorTime>(); try { var config = new CsvConfiguration(CultureInfo.InvariantCulture) { // Don't write the header again. HasHeaderRecord = false, }; using (var reader = new StreamReader(@"D:\Reports\" + runId + @"\LocatorTime.csv")) using (var csv = new CsvReader(reader, config)) { //csv.Context.RegisterClassMap<LocatorTime>(); records = csv.GetRecords<LocatorTime>().ToList(); foreach (var record in records) { if (record.RunID == runId) { record.TimeTakenByLocatorJSON = DateTime.Now; } // Console.WriteLine("inside loop"); } }//Endof Stream Reader using (var stream = File.Open(@"D:\Reports\" + runId + @"\LocatorTime.csv", FileMode.Append)) //not sure what the file mode should be using (var writer = new StreamWriter(stream)) using (var csv = new CsvWriter(writer, CultureInfo.InvariantCulture)) { csv.WriteRecords(records); } } catch (Exception e) { Console.WriteLine(e); } }//end func writeEnd
This is the class used for the csv file & are also the column names in the csvfile public class LocatorTime { public string RunID { get; set; } public string ProductArea { get; set; } public string Product { get; set; } public string Component { get; set; } public string PageObject { get; set; } public string Control { get; set; } public DateTime TimeTakenByLocatorJSON //only this value needs to be written for update at end of exec { get; set; }/*error because of DateTime datatype how to resolve?*/ }//LocatorTimeClass /*public void SetExeDate() //tried this for removing DateTime error, didn't work { DateTime today = DateTime.Today; // As DateTime string s_today = today.ToString("yyyy-MM-dd"); // As String //TimeTakenByLocatorJSON = s_today.Trim(); TimeTakenByLocatorJSON = Convert.ToDateTime(s_today);} */ public sealed class LocatorTimeMap : ClassMap<LocatorTime> //is mapping helpful for updating? currently commented out { public LocatorTimeMap() { Map(m => m.RunID).Index(0); Map(m => m.ProductArea).Index(1); Map(m => m.Product).Index(2); Map(m => m.Component).Index(3); Map(m => m.PageObject).Index(4); Map(m => m.Control).Index(5); Map(m => m.TimeTakenByLocatorJSON).Index(6); //error } }
I had used the below link as reference for trying to update the CSV file hence the use of "HasHeaderRecord = false" https://joshclose.github.io/CsvHelper/examples/writing/appending-to-an-existing-file/  |

| Non destructive modify hash table Posted: 02 Nov 2021 08:16 AM PDT Is it possible to non-destructively add new key-value pairs to a Common Lisp (SBCL) hash table? The standard way to add new elements to a hash table is to call: (setf (gethash key *hash-table*) value)
but the call to setf modifies *hash-table* corrupting the original. I have an application where I'd like to take advantage of the efficiency of hash table lookups, but I also would like to non destructively modify them. The work-around I see is to copy the original hash table before operating on it, but that is not practical in my case since the hash tables I'm dealing with contain many thousands of elements and copying large hash tables, say, in a loop would negate the computational efficiency advantage of using them in the first place.  |
| RecyclerView in ViewPager won't Scroll Posted: 02 Nov 2021 08:16 AM PDT In my app I have my main page, in it a ViewPager. I can navigate between fragments in the ViewPager using a drawerLayout. One of the fragments is a RecyclerView (in a FrameLayout). The problem is I cannot scroll the RecyclerView. I've asked a question of the sort before, and got the solution, only it was a ScrollView instead of RecyclerView, and the ViewPager was in a ConstraintLayout, and now it has to be in a RelativeLayout so the drawerLayout could exist. code of the layouts: activity_main.xml: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/mainScreenContainer" android:layout_width="match_parent" android:layout_height="match_parent" android:background="?attr/colorPrimary" tools:context=".MainActivity"> <include android:id="@+id/mainToolbar" layout="@layout/main_toolbar_layout" /> <com.google.android.material.tabs.TabLayout android:id="@+id/mainTabLayout" android:layout_width="0dp" android:layout_height="0dp" android:visibility="gone"> <com.google.android.material.tabs.TabItem android:id="@+id/main" android:layout_width="match_parent" android:layout_height="0dp" /> <com.google.android.material.tabs.TabItem android:id="@+id/activeGoals" android:layout_width="match_parent" android:layout_height="0dp" /> <com.google.android.material.tabs.TabItem android:id="@+id/achievedGoals" android:layout_width="match_parent" android:layout_height="0dp" /> <com.google.android.material.tabs.TabItem android:id="@+id/stats" android:layout_width="match_parent" android:layout_height="0dp" /> <com.google.android.material.tabs.TabItem android:id="@+id/tipsAndTricks" android:layout_width="match_parent" android:layout_height="0dp" /> <com.google.android.material.tabs.TabItem android:id="@+id/aboutUs" android:layout_width="match_parent" android:layout_height="0dp" /> </com.google.android.material.tabs.TabLayout> <androidx.viewpager.widget.ViewPager android:id="@+id/mainViewPager" android:layout_width="match_parent" android:layout_height="0dp" android:layout_alignParentBottom="true" android:layout_below="@id/mainToolbar"/> <androidx.drawerlayout.widget.DrawerLayout android:id="@+id/drawerLayout" android:layout_width="match_parent" android:layout_height="match_parent" android:fitsSystemWindows="true" android:layout_below="@id/mainToolbar"> <com.google.android.material.navigation.NavigationView android:id="@+id/list_nav_drawer" android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_gravity="start" app:menu="@menu/menu_items" /> </androidx.drawerlayout.widget.DrawerLayout> </RelativeLayout>

| Object returning NaN when sum values Posted: 02 Nov 2021 08:17 AM PDT I'll admit I'm weak in JavaScript and JSON. I've spent a lot of time attempting to figure out why numbers from my objects returns NaN when they are added together. With that in mind, below is my JSON, stored to a variable: var data = [ { "acc_ext_id": null, "cat_code": 10002, "cat_ds": "REVENUE", "category_id": null, "chart_id": null, "created_at": null, "dept_id": null, "feb": null, "id": null, "jan": 30, "note": null, "total_cost": null, "updated_at": null, "year_id": null }, { "acc_ext_id": "41260-02600", "cat_code": 10002, "cat_ds": "REVENUE", "category_id": 2, "chart_id": 2373, "created_at": "2013-01-15 16:43:52.169213", "dept_id": 86, "feb": 45, "id": 3, "jan": 60, "note": "Two", "total_cost": 105, "updated_at": "2013-01-15 16:43:52.169213", "year_id": 1 } ]
I then attempt to iterate over the objects and sum the values: var jan; for (var i=0;i<data.length;i++){ if(data[i].jan != null){ jan += parseFloat(data[i].jan); console.log(jan); } }
Printed out in the console is NaN. I've attempted to parse the number as well as leave it raw, but to no avail. Is there something wrong with my objects? Here is a jsFiddle to illustrate: http://jsfiddle.net/5E2pm/3/  |
| Javascript fade in fade out without Jquery and CSS3 Posted: 02 Nov 2021 08:16 AM PDT I am really squeezing my head to make the simple fade in and fade out of the background image work only with javascript without JQuery and CSS3. I know how easy is to call a fadeIn() and fadeOut() in Jquery. Unfortunately in my project I am working, they don't support Jquery. I want to support the animation from IE6 for your info. On click of the links the corresponding background of the div to be faded in and out from the previously existing background. I am trying to make it work based on setinterval but could not do it. function handleClick(evt){ var element = document.getElementsByClassName(evt.target.id); fade(element); } function fade(element) { var op = 1; // initial opacity var timer = setInterval(function () { if (op <= 0.1){ clearInterval(timer); element.style.display = 'none'; } element.style.opacity = op; element.style.filter = 'alpha(opacity=' + op * 100 + ")"; op -= op * 0.1; }, 50); }
