| Leading white space truncated by "set /p x=" Posted: 10 Jul 2021 08:01 AM PDT A script to manage incoming files generates an audit trail that logs transaction sets made up of a header record, several transaction records and a trailer record. A single line is written with delimiters, a string for the header, one each for the transactions and finally the trailer. Its fairly simple and the code snippet below describes it perfectly. There is, however, a flaw in the ointment, and one that's been around since XP transitioned out: sometimes the id in the transaction has a leading space, and cmd strips this out. dbenham posted its awfulness here and I'm hoping someone might have chanced on a solution to the bug? feature? issue. The following example shows this, with the first line having leading spaces, and the second replacing the leading and trailing spaces with an underscore by way of contrast, and to see what happens during expansion. The leading space is truncated, the trailing space retained. A delimiter is sent after each string. wrapping the set command in quotes makes no difference. TEST OUTPUT: no 1 line:header:leading space:leading trailing spaces :leadingtrailing pipe : no 2 line:header:_leading char:_leading trailing chars__:_leadingtrailing pipe_:
SAMPLE CODE: type nul>file.txt >>file.txt (<nul set /p x=no 1 line) &&rem first line >>file.txt (<nul set /p x=:) &&rem delimiter >>file.txt (<nul set /p x=header) >>file.txt (<nul set /p x=:) (<nul set /p x= leading space)1>>file.txt &&rem leading space >>file.txt (<nul set /p x=:) (<nul set /p "x= leading trailing spaces ")1>>file.txt &&rem leading space, trailing space >>file.txt (<nul set /p x=:) echo|set /p=" leadingtrailing pipe ">>file.txt >>file.txt (<nul set /p x=:) >>file.txt echo:&&rem force a newline to begin line no 2. >>file.txt (<nul set /p x=no 2 line) &&rem writes to index 1 >>file.txt (<nul set /p x=:) >>file.txt (<nul set /p "x=header") &&rem no leading, no trailing >>file.txt (<nul set /p x=:) (<nul set /p "x=_leading char")1>>file.txt &&rem leading '_' >>file.txt (<nul set /p x=:) (<nul set /p "x=_leading trailing chars__")1>>file.txt &&rem leading, trailing '_' >>file.txt (<nul set /p x=:) echo|set /p="_leadingtrailing pipe_">>file.txt >>file.txt (<nul set /p x=:) rem no newline to avoid a trailing carriage return
CODE EXPANSION: (where the leading white space is stripped out) (set /p x= leading space 0<nul ) 1>>file.txt && rem leading space (set /p "x= leading trailing spaces " 0<nul ) 1>>file.txt && rem leading and trailing'_'
My workaround is to replace any leading spaces in the header id with underscores, and then restore the spaces after the run completes. This works fine because none of the incoming records have an underscore in their id. It would be nice, though, to be able to remove the work-around.  |

| Php 7.4.3 Class not found Posted: 10 Jul 2021 08:01 AM PDT This is my project path configuration ./create.php

Can someone explain me what is happening there ?

| Building an auto-design tool using multi-task learning methods Posted: 10 Jul 2021 08:01 AM PDT I am currently working as a MLE for a startup in the e-commerce space and have recently been tasked with developing a ML model to personalize landing/web pages based on user account data as well as text data that the user provides beforehand. Without getting too deep into the company jargon and weeds my inputs are as follows: BERT embeddings generated from the long form text provided by user Account info and standard headers from http requests My target output is generating a series of parameters/categories that go into a config file (json) that set the formatting of the page, there are roughly ~30 of these, each having roughly ~10 options within, ex: "border color: #fffffff" or " positonalElement4: #000000" and so on... I have existing configs that have been previously generated (randomly) but selected by a user. My question for the sub is as follows: How would you recommend architecting a system that can learn these parameters? My current approach is to utilize multi-task learning to build a unified trunk (backbone) and have a head for each param. This will result in roughly 30 heads. Does this seem doable / reasonable? If anyone knows of any other projects that have been done that are similar to this use case please let me know, any research papers or github links would be appreciated.  |

| How do I properly integrate a modular boost build into my CMake project using FetchContent? Posted: 10 Jul 2021 08:01 AM PDT CMake FetchContent is a great way to manage build dependencies, by integration the dependency into your build and build it from source along with your own sources. I would like to do this with Boost, too. I am encouraged by the fact that CMake support for Boost is steadily improving. Of course since Boost is a large package, and one rarely uses all Boost libraries in a project, it would be rather wasteful to pull the entire Boost sources into one's own build. Given the modularity of the Boost project, using git submodules, it would be much more intelligent and efficient to only fetch the sources for the libraries actually used, and FetchContent supports this via its GIT_SUBMODULES option. However, this doesn't seem to cater for dependencies between the Boost libraries. Do I need to handle this manually, or is there a more intelligent solution? Furthermore, how do I control installation in this scenario? Many Boost libraries are header-only, and I don't want the headers included in my installation, since I'm only using them for my build. Is there a way to tell CMake that I don't want anything installed from what I fetch with FetchContent? I have read Craig Scott's book, and of course the CMake documentation, but there's not much information about this sort of problem. But maybe I'm trying something that I shouldn't be doing. Have others tried this, and can show me how it's done properly?  |

| How to nest and group results in Gremlin (CosmosDB) Posted: 10 Jul 2021 07:59 AM PDT I am connecting vertices like so: {user} --> owns --> {computer} --> controls --> {program} --> has --> {features}
I want to list all the computers, programs and features accessible to a user. Preferably in the following JSON format: { userName: Foo, id: XX-1, ownedComputers: [ { computerName: Office-1, computerType: PC installedPrograms: [ { programID: XX-1, programName: FizzBuz programFeatures: [ { access: remote-connection, sudo: required, } }, { programID: XX-1, programName: FizzBuz programFeatures: [ { access: remote-connection, sudo: required, } }, ] }, ... {computer #2} ... ] }
My query looks like this: g.V().has('user', 'id','XX-1').as('selectedUser').out('owns').as('ownedComputers').out('controls').as('installedPrograms').out('has').as('programFeatures').select('selectedUser','ownedComputer','installedPrograms','programFeatures').unfold().dedup()

My query doesn't get me over the line because: - no pretty JSON -- not sure how to use map() and valueMap() to get rid of all unwanted ids.
- installedPrograms are just listed after the ownedComputer, I want them grouped and nested as shown above in my preferred format -- haven't figured out how to use store() or group().
- similarly for programFeatures, these should be grouped together and then nested under installedPrograms.
Any help would be greatly appreciated!  |

To do that I tried to make object mechanics static. pub fn main() { let mut mechanics : &'static Mechanics = &'static mut Mechanics { val : 13. }; let mut renderer = Render::new( "solution1".to_string() ); renderer.f_on_update = Box::new( || { println!( "mechanics.val : {}", mechanics.val ) }); renderer.update(); } // struct Mechanics { val : f32, } // struct Render { name : String, f_on_update : Box< dyn Fn() >, } // impl Render { fn new( name : String ) -> Self { let f_on_update = || {}; Self { name, f_on_update : Box::new( f_on_update ) } } fn update( &self ) { (self.f_on_update)(); } }
But I get the error: error: borrow expressions cannot be annotated with lifetimes --> src/static_solution_1.rs:4:44 | 4 | let mut mechanics : &'static Mechanics = &'static mut Mechanics { val : 13. }; | ^-------^^^^^^^^^^^^^^^^^^^^^^^^^^^^ | | | annotated with lifetime here | help: remove the lifetime annotation
Changing to let mut mechanics : &'static Mechanics = &Mechanics { val : 13. };
Gives the error: error[E0597]: `mechanics` does not live long enough --> src/static_solution_1.rs:8:37 | 6 | renderer.f_on_update = Box::new( || | - -- value captured here | __________________________| | | 7 | | { 8 | | println!( "mechanics.val : {}", mechanics.val ) | | ^^^^^^^^^ borrowed value does not live long enough 9 | | }); | |____- cast requires that `mechanics` is borrowed for `'static` 10 | renderer.update(); 11 | } | - `mechanics` dropped here while still borrowed
I do something wrong but have no clue where to look for an answer. Reading about static lifetime didn't help me to overcome the obstacle. Any suggestion?  |
| Is there any simple way to preserve original indices after sorting array without using Comparator? Posted: 10 Jul 2021 08:00 AM PDT I implemented an array in which I've taken one array which is zero-indexed. Consider the array below : Array : X S T U A C D B F H Index : 0 1 2 3 4 5 6 7 8 9 After sorting this array : Array : A B C D F H S T U X Index : 0 1 2 3 4 5 6 7 8 9 Original indices : 4 7 5 6 8 9 1 2 3 0
Earlier A was at index 4 but in the sorted array, it is at index 0 and the same for other values. The output expected from the program is represented as original indices. Instead of printing the elements in the sorted array, I want to print their original indices after they are sorted. Although this code is working properly, But I want to know if there is any other simple technique that we can use to preserve the original array indices without using Comparator. The idea here is to preserve the index and hence I am using Comparator : In this Comparator, I preserved the actual array which is to be sorted. Also, if you notice, the compare method compares the values of the actual array based on the indices supplied to it. The key here is to supply the indices and not the actual values to be sorted. S is the character array to be sorted, indexArray is an auxiliary array. Before sorting, the index array will contain numbers in a sequence 0 – length of the array to be sorted. When I invoked the Arrays.sort method on the index array, it passes the two indices to the compare method and compares the values stored at those indices. ```public class ArrayIndexComparator implements Comparator<Integer> { private final Character[] A; public ArrayIndexComparator(Character[] arr) { this.A = arr; } public int compare(Integer o1, Integer o2) { return A[o1].compareTo(A[o2]); } }``` ```public static void main(String[] args) { Character[] S = new Character[]{'X','S','T','U','A','C','D','B','F','H'}; Integer[] indexArray = new Integer[S.length]; IntStream.range(0, S.length).forEach(val -> indexArray[val] = val); ArrayIndexComparator comp = new ArrayIndexComparator(S); Arrays.sort(indexArray, comp); System.out.println(Arrays.toString(indexArray)); }```

| How can I display data between specified dates and get a summation of only those data's? Posted: 10 Jul 2021 08:01 AM PDT So I am using PHP and MySQL(PDO). I have a form that is a lot like the table image below in which the user is gonna input data (almost) every day. Data Entry Example: | Date | Old Case(1) | New Case(2) | Total Case(1+2) | Discharge | Conviction | Acquittal | Other | | 12-06-2021 | 1000 | 500 | 1500 | 30 | 40 | 18 | 0 | | 13-06-2021 | 1500 | 200 | 1700 | 10 | 14 | 23 | 9 | | 14-06-2021 | 1700 | 100 | 1800 | 19 | 33 | 23 | 18 | | 15-06-2021 | 1800 | 200 | 2000 | 32 | 18 | 07 | 21 | And later maybe he would want to get the total number of data between two specified dates which the user would specify.Here is also another question of mine. How will the user specify the dates?. for example, he would select the 'from' date"01-January-2021" and the 'to' date "01-February-2021" after selection he would enter submit button, and then there would be a table shown in the website like below where the total "Discharge" number, total "Conviction", total "Acquittal" and total "Others" numbers between those dates would show. Final Output: | Date(Between Two Dates) | Last Entry Old Case in Date Range(1) | Last Entry New Case in Daterange(2) | Total Case(1+2) | Total Discharge | Total Conviction | Total Acquittal | Total Other | | 12-6-2021 to 15-6-2021 | 1800 | 200 | 2000 | 91 | 105 | 71 | 48 | Now how can I do this function? I am not being able to figure out the function where all the data between selected dates would get total up according to their fields and then display the totaled results! Do I need to use Ajax? DB-FIDDLE(I have never used this before so don't really know how to use it properly.): https://www.db-fiddle.com/f/goPRNPA8Q6QRkn258sdrsd/1 Another Question: I thought I would be able to figure this issue on my own but I couldn't after trying the whole day. So There are three other columns in my database (after updating the colums). They are "Old Case", "New Case" and the total of these two columns "Total Cases". This "Total Case" becomes the "Old Case" for the next entry or date. And in my Final Output, It would show the last entered "Old Case" and "New Case" between the selected "DateRange". But I am not being able to figure out how I can implement this. Can anyone help me, please?  |
| .NET SqlClient - Timeout expired Posted: 10 Jul 2021 07:59 AM PDT Currently i am building an query on a database in .net core. One of the querys has many different filters like the following example: IQueryable<OperatingInstructionDTO> newQuery = this.Database.Set<OperatingInstructionDTO>() .Include(x => x.CurrentState) .Include(x => x.Plant) .Include(x => x.Department) .Include(x => x.Creator) .Where(x => x.Type != null && x.Type.Equals(type) && x.Department.Id == user.Department.Id); if (filter.InstructionTitle != null) newQuery = newQuery.Where(x => x.Title.Contains(filter.InstructionTitle)); if (filter.SelectedStates != null) newQuery = newQuery.Where(x => filter.SelectedStates.Contains(x.CurrentState.Description)); if (filter.SelectedEditors != null && filter.SelectedEditors.Count == 1) { if (filter.SelectedEditors[0].Equals("Eigene")) newQuery = newQuery.Where(x => x.Creator.Email.Equals(user.Email)); else newQuery = newQuery.Where(x => !x.Creator.Email.Equals(user.Email)); } if (filter.OverallTextFilter != null) newQuery = newQuery.Where(x =>x.Content!=null && x.Content.Contains(filter.OverallTextFilter)); newQuery = newQuery.OrderByDescending(x => x.CreationTimestamp).ThenBy(x => x.Title).Take(filter.SelectedNumberOfResults); return newQuery.Select(x => new OperatingInstructionDTO { CreationTimestamp = x.CreationTimestamp, CurrentState = x.CurrentState, Department = x.Department, ParentOperatingInstruction = new OperatingInstructionDTO { }, Plant = x.Plant, Title = x.Title, Id = x.Id, Creator = x.Creator, Type = x.Type }).ToList();
If i set the filter OverallTextFilter the execution is very slow. I know this but this feature is needed for the customer. Because the exection is so slow i get the following error message: System.Data.SqlClient.SqlException HResult=0x80131904 Message=Timeout expired.

| GORM query to find all the records of a table which are not null for its contact field given a name field Posted: 10 Jul 2021 08:02 AM PDT I have a table in sqlite which consists of three columns, i.e. Name, Surname and Contact_Number. The scenario is, that I am given any name(which is present in the database) and I have to find all the records which are related with that name and have Contact_Number "NOT NULL". (There can be multiple contact numbers for a name, and they are stored each as a different record, For example: Name Surname Contact_Number Ajay Naik 1234 Ajay Naik 6789 Ajay Naik null So the query in GORM should return Upper two records on the name Ajay.  |
| Jaxb marshaling primitive types Posted: 10 Jul 2021 08:00 AM PDT I have a class with primitive types double and long. While marshaling i have to avoid the variables containing zero value. Tried @XmlJavaTypeAdapter and inside the same tried to return null values- but failed. Is there a way? Searched other threads and cant find a solution  |
