  • Groovy list.sort by first, second then third elements

    - by Ying
    Hi, I have a groovy list of lists i.e. list = [[2, 0, 1], [1, 5, 2], [1, 0, 3]] I would like sort it by order of the first element, then second, then third. Expected assert list == [[1, 0, 3], [1, 5, 2], [2, 0, 1]] I started with list = list.sort{ a,b -> a[0] <=> b[0] } but that only sorts the first element. How do you finish? Thanks

  • What are the pros and cons of using manual list iteration vs recursion through fail

    - by magus
    I come up against this all the time, and I'm never sure which way to attack it. Below are two methods for processing some season facts. What I'm trying to work out is whether to use method 1 or 2, and what are the pros and cons of each, especially large amounts of facts. methodone seems wasteful since the facts are available, why bother building a list of them (especially a large list). This must have memory implications too if the list is large enough ? And it doesn't take advantage of Prolog's natural backtracking feature. methodtwo takes advantage of backtracking to do the recursion for me, and I would guess would be much more memory efficient, but is it good programming practice generally to do this? It's arguably uglier to follow, and might there be any other side effects? One problem I can see is that each time fail is called, we lose the ability to pass anything back to the calling predicate, eg. if it was methodtwo(SeasonResults), since we continually fail the predicate on purpose. So methodtwo would need to assert facts to store state. Presumably(?) method 2 would be faster as it has no (large) list processing to do? I could imagine that if I had a list, then methodone would be the way to go.. or is that always true? Might it make sense in any conditions to assert the list to facts using methodone then process them using method two? Complete madness? But then again, I read that asserting facts is a very 'expensive' business, so list handling might be the way to go, even for large lists? Any thoughts? Or is it sometimes better to use one and not the other, depending on (what) situation? eg. for memory optimisation, use method 2, including asserting facts and, for speed use method 1? season(spring). season(summer). season(autumn). season(winter). % Season handling showseason(Season) :- atom_length(Season, LenSeason), write('Season Length is '), write(LenSeason), nl. % ------------------------------------------------------------- % Method 1 - Findall facts/iterate through the list and process each %-------------------------------------------------------------- % Iterate manually through a season list lenseason([]). lenseason([Season|MoreSeasons]) :- showseason(Season), lenseason(MoreSeasons). % Findall to build a list then iterate until all done methodone :- findall(Season, season(Season), AllSeasons), lenseason(AllSeasons), write('Done'). % ------------------------------------------------------------- % Method 2 - Use fail to force recursion %-------------------------------------------------------------- methodtwo :- % Get one season and show it season(Season), showseason(Season), % Force prolog to backtrack to find another season fail. % No more seasons, we have finished methodtwo :- write('Done').

  • Converting a string into a list in Python

    - by Sam
    I have a text document that contains a list of numbers and I want to convert it to a list. Right now I can only get the entire list in the 0th entry of the list, but I want each number to be an element of a list. Does anyone know of an easy way to do this in Python? 1000 2000 3000 4000 to ['1000','2000','3000','4000']

  • Circle values that don't match any of the ones in a dropdown list

    - by Robert4242
    I created a dropdown list with values and assigned them to one of the columns in a table. When I changed a few, then changed the name of items in the list and removed some I accidentally did some key combination somewhere around Ctrl+Z or Ctrl+Y and Excel highlighted cells in the table that had a value not on the list. The highlighting looks like a red oval around each such cell. How can I toggle it on and off?

  • How to edit multilevel list in Word 2011 Mac

    - by Tim Kemp
    I use the multilevel list feature in Word as described here to set up proper nested numbering linked to styles. I did this on Windows, and it worked well. Now I am editing the documents on my Mac using Word 2011. I need to modify the list style; I can create a new multi-level list style from the toolbar dropdown, but I can't right-click to edit an existing one. How can I edit my existing list style on Word for Mac? Thanks

  • Estimating compressed file size using a list parameter

    - by Sai
    I am currently compressing a list of files from a directory in the following format: tar -cvjf test_1.tar.gz -T test_1.lst --no-recursion The above command will compress only those files mentioned in the list. I am doing this because this list is generated such that it fits a DVD. However, during compression the compression rate decreases the estimated file size and there is abundant space left in the DVD. This is something like a Knapsack algorithm. I would like to estimate the compressed file size and add some more files to the list. I found that it is possible to estimate file size using the following command: tar -cjf - Folder/ | wc -c This command does not take a list parameter. Is there a way to estimate compressed file size? I am also looking into options like perl scripts etc. Edit: I think I should provide more information since I have been doing a lot of web search. I came across a perl script(Link)that sort of emulates the Knapsack algorithm. The current problem with the above mentioned script is that it splits the files in their original state. When I compress the files after splitting them, there are opportunities for adding more files which I consider to be inefficient. There are 2 ways I could resolve the inefficiency: a) Compress individual files and save them in a directory using a script. The compressed file could provide a best estimate. I could generate a script using a folder of compressed files and use them on the uncompressed ones. b) Check whether the compressed file's size is less than the required size. If so, I should keep adding files until I meet the requirement. However, the addition of new files to the compressed file is an optimization problem by itself.

  • Access Google Apps Global Address List from Thunderbird

    - by Roy
    We're considering using Google Apps as groupware, with our Mac and Linux users (and likely a few of the Windows users as well) accessing mail and calendar using Thunderbird with Lightning. We seem to have worked out most features, but have not found a way to access Global Address List. Is there a way to sync the Global Address List to Thunderbird? Update: The Zindus addon as suggested by @superuser, does not have support for Global Address List from Google Apps (it does however support GAL from a Zimbra server)

  • Descending list ordered by file modification time

    - by user62367
    How can i generate a list of files in a directory [e.g.: "/mnt/hdd/PUB/"] ordered by the files modification time? [in descending order, the oldest modified file is at the lists end] ls -A -lRt would be great: https://pastebin.com/raw.php?i=AzuSVmrJ but if a file is changed in a directory it lists the full directory...so the pastebined link isn't good [i don't want a list ordered by "directories", i need a "per file" ordered list] os: openwrt..[no perl - not enough space for it :( + no "stat", or "file" command] Thank you!

  • Vim - dynamic list of open buffers in a window

    - by asfallows
    I've investigated a few ways to maintain a list of open buffers in Vim, and some of them are very good, but none of them seem to behave the way I'd like. It's very possible that nothing like what I want exists, and it can't hurt to ask. I've been using NERDTree in GVim, and I like the idea of putting the information in a slender left-hand window. I've put together a handy diagram for how I'd like my environment to look: |--------|---------------------------------------| | | | | | | |NERDTree| Windows | | | | | | | | | | |--------| | | | | | | | | List | | | of | | | Open | | | Buffers| | | | | | | | |--------|---------------------------------------| So my question is: Is there a vim-native or plugin-enabled way to maintain a list of currently open buffers and select/edit/close from that list, inside a window similar to NERDTree? I understand that this approach may be incongruous with the Vim way of doing things, and if you feel like I'm missing something about how to manage multiple files in a Vim session, please leave a comment with suggestions!

  • script to list user's mapped drive not giving results or error

    - by user223631
    We are in the process of migrating two file servers to a new server. We have mapped drives via user group in group policy. Many users have manually mapped drives and we need to find these mappings. I have created a PowerShell script to run that remotely get the drive mappings. It works on most computers but there are many that are not returning results and I am not getting any error messages. Each workstation on the list creates a text file and the ones that are not returning results have no text in the files. I can ping these machines. If the machine is not turned on, it does come up error message that the RPC server is not available. My domain user account is in a group that is in the local admin account. I have no idea why some are not working. Here is the script. # Load list into variable, which will become an array of strings If( !(Test-Path C:\Scripts)) { New-Item C:\Scripts -ItemType directory } If( !(Test-Path C:\Scripts\Computers)) { New-Item C:\Scripts\Computers -ItemType directory } If( !(Test-Path C:\Scripts\Workstations.txt)) { "No Workstations found. Please enter a list of Workstations under Workstation.txt"; Return} If( !(Test-Path C:\Scripts\KnownMaps.txt)) { "No Mapping to check against. Please enter a list of Known Mappings under KnownMaps.txt"; Return} $computerlist = Get-Content C:\Scripts\Workstations.txt # Loop through each item in the array (each computer in the list of computers we loaded into the variable) ForEach ($computer in $computerlist) { $diskObject = Get-WmiObject Win32_MappedLogicalDisk -computerName $computer | Select Name,ProviderName | Out-File C:\Tester\Computers\$computer.txt -width 200 } Select-String -Path C:\Tester\Computers\*.txt -Pattern cmsfiles | Out-File C:\Tester\Drivemaps-all.txt $strings = Get-Content C:\Tester\KnownMaps.txt Select-String -Path C:\Tester\Drivemaps-all.txt -Pattern $strings -notmatch -simplematch | Out-File C:\Tester\Drivemaps-nonmatch.txt -Width 200 Select-String -Path C:\Tester\Drivemaps-all.txt -Pattern $strings -simplematch | Out-File C:\Tester\Drivemaps-match.txt -Width 200

  • Organizing a random list of objects in Python.

    - by Saebin
    So I have a list that I want to convert to a list that contains a list for each group of objects. ie ['objA.attr1', 'objC', 'objA.attr55', 'objB.attr4'] would return [['objA.attr1', 'objA.attr55'], ['objC'], ['objB.attr4']] currently this is what I use: givenList = ['a.attr1', 'b', 'a.attr55', 'c.attr4'] trgList = [] objNames = [] for val in givenList: obj = val.split('.')[0] if obj in objNames: id = objNames.index(obj) trgList[id].append(val) else: objNames.append(obj) trgList.append([val]) #print trgList It seems to run a decent speed when the original list has around 100,000 ids... but I am curious if there is a better way to do this. Order of the objects or attributes does not matter. Any ideas?

  • Mailing list with dynamically generated addresses

    - by Joe Tomasone
    I am trying to implement a dynamic mailing list from a database that changes quite often. Conditions: Postfix is the MTA Email addresses are in a MySql Database Postfix only allows senders whose emails are in that database (via smtpd_sender_restrictions) Cron job extracts the current emails from the database nightly and puts them into an alias file, then runs postalias on it. This works well, but since the sender remains the same, many domains are rejecting the email since my server is not a DNS listed mail server for the sender's domain. So, I either have to find a way to re-write the outgoing address as "listserv@mydomain" or find some mailing list package that will use database-retrieved emails (either queried directly or in a flat file) as the subscriber list, with that list replaced daily. I've tried Sympa and am pretty much ready to give up on it - it's a nightmare to get working right - but that's the only open source listserver that I have seen that works with dynamic mail lists. Does anyone have any ideas? Thanks, Joe

  • Getting a list of packages installed on CentOS (by command line and on the web)

    - by sameold
    When installing CentOS (6.2), it installs a whole bunch of packages, but the installation is often very fast, it's hard to note the names of the packages. I have a couple of questions: 1) I'm guessing I could wait for the entire installation to complete and then query for the list of installed packages on the system. How do I do that? 2) Is there a printed list somewhere on the web, so I don't have to install the OS first just to get the list?

  • Creating a list based on a column

    - by MikkoP
    I need to create a dropdown list in sheet A based on the values in sheet B in column A. I clicked on the A column in B sheet and named it as Models. Then I clicked on the cell in sheet A where I wanted the list to be and selected Data -> Data validation -> Data validation. In the Settings page I selected List in the Allow section, checked Ignore blank and In-cell dropdown. In the Source section I inserted =Models. This way I get all the right values plus a lot of blank values. How do I prevent the blank lines from appearing in the list?

  • Creating Dynamic Objects

    - by Ramesh Durai
    How to dynamically create objects? string[] columnNames = { "EmpName", "EmpID", "PhoneNo" }; List<string[]> columnValues = new List<string[]>(); for (int i = 0; i < 10; i++) { columnValues.Add(new[] { "Ramesh", "12345", "12345" }); } List<Dictionary<string, object>> testData = new List<Dictionary<string, object>>(); foreach (string[] columnValue in columnValues) { Dictionary<string, object> data = new Dictionary<string, object>(); for (int j = 0; j < columnNames.Count(); j++) { data.Add(columnNames[j], columnValues[j]); } testData.Add(data); } Imaginary Class(Class is not available in code): class Employee { string EmpName { get;set; } string EmpID { get;set; } string PhoneNo { get;set; } } Note: Property/column names are dynamic. Now I want to convert the List<Dictionary<string, object>> to a class of type List<object> (i.e) List<Employee>. Is it Possible? Suggestions please.

  • WCF: Serializing and Deserializing generic collections

    - by Fabiano
    I have a class Team that holds a generic list: [DataContract(Name = "TeamDTO", IsReference = true)] public class Team { [DataMember] private IList<Person> members = new List<Person>(); public Team() { Init(); } private void Init() { members = new List<Person>(); } [System.Runtime.Serialization.OnDeserializing] protected void OnDeserializing(StreamingContext ctx) { Log("OnDeserializing of Team called"); Init(); if (members != null) Log(members.ToString()); } [System.Runtime.Serialization.OnSerializing] private void OnSerializing(StreamingContext ctx) { Log("OnSerializing of Team called"); if (members != null) Log(members.ToString()); } [System.Runtime.Serialization.OnDeserialized] protected void OnDeserialized(StreamingContext ctx) { Log("OnDeserialized of Team called"); if (members != null) Log(members.ToString()); } [System.Runtime.Serialization.OnSerialized] private void OnSerialized(StreamingContext ctx) { Log("OnSerialized of Team called"); Log(members.ToString()); } When I use this class in a WCF service, I get following log output OnSerializing of Team called System.Collections.Generic.List 1[Person] OnSerialized of Team called System.Collections.Generic.List 1[Person] OnDeserializing of Team called System.Collections.Generic.List 1[ENetLogic.ENetPerson.Model.FirstPartyPerson] OnDeserialized of Team called ENetLogic.ENetPerson.Model.Person[] After the deserialization members is an Array and no longer a generic list although the field type is IList< (?!) When I try to send this object back over the WCF service I get the log output OnSerializing of Team called ENetLogic.ENetPerson.Model.FirstPartyPerson[] After this my unit test crashes with a System.ExecutionEngineException, which means the WCF service is not able to serialize the array. (maybe because it expected a IList<) So, my question is: Does anybody know why the type of my IList< is an array after deserializing and why I can't serialize my Team object any longer after that? Thanks

  • c# finding matching words in table column using Linq2Sql

    - by David Liddle
    I am trying to use Linq2Sql to return all rows that contain values from a list of strings. The linq2sql class object has a string property that contains words separated by spaces. public class MyObject { public string MyProperty { get; set; } } Example MyProperty values are: MyObject1.MyProperty = "text1 text2 text3 text4" MyObject2.MyProperty = "text2" For example, using a string collection, I pass the below list var list = new List<>() { "text2", "text4" } This would return both items in my example above as they both contain "text2" value. I attempted the following using the below code however, because of my extension method the Linq2Sql cannot be evaluated. public static IQueryable<MyObject> WithProperty(this IQueryable<MyProperty> qry, IList<string> p) { return from t in qry where t.MyProperty.Contains(p, ' ') select t; } I also wrote an extension method public static bool Contains(this string str, IList<string> list, char seperator) { if (String.IsNullOrEmpty(str) || list == null) return false; var splitStr = str.Split(new char[] { seperator }, StringSplitOptions.RemoveEmptyEntries); foreach (string s in splitStr) foreach (string l in list) if (String.Compare(s, l, true) == 0) return true; return false; } Any help or ideas on how I could achieve this?

  • Copy a LinkedList that has a Random Pointer in it

    - by Bragaadeesh
    Hi, First of all this is not a homework, this is an interview question that I got from a company I attended today. You have a singly linked list with the Node structure as the following class Node{ int data; Node next; Node random; } You have a typical singly linked list of length n. The random pointer in each node in the linkedlist randomly points to some Node within the linked list. The Question is to create a copy of the linked list efficiently into a different LinkedList. I said that I will first calculate the Random pointer's position in the linked list and store it in an array. Then create a new linked list normally. Then iterate through the linked list by setting the random pointer where they belong by reading the values stored from the array. I know its a very brute force technique and the interviewer asked me to come up with a better solution but I couldnt. Please can someone answer this? I can explain if the question is not clear.

  • How would I compare two Lists(Of <CustomClass>) in VB?

    - by Kumba
    I'm working on implementing the equality operator = for a custom class of mine. The class has one property, Value, which is itself a List(Of OtherClass), where OtherClass is yet another custom class in my project. I've already implemented the IComparer, IComparable, IEqualityComparer, and IEquatable interfaces, the operators =, <>, bool and not, and overriden Equals and GetHashCode for OtherClass. This should give me all the tools I need to compare these objects, and various tests comparing two singular instances of these objects so far checks out. However, I'm not sure how to approach this when they are in a List. I don't care about the list order. Given: Dim x As New List(Of OtherClass) From {New OtherClass("foo"), New OtherClass("bar"), New OtherClass("baz")} Dim y As New List(Of OtherClass) From {New OtherClass("baz"), New OtherClass("foo"), New OtherClass("bar")} Then (x = y).ToString should print out True. I need to compare the same (not distinct) set of objects in this list. The list shouldn't support dupes of OtherClass, but I'll have to figure out how to add that in later as an exception. Not interested in using LINQ. It looks nice, but in the few examples I've played with, adds a performance overhead in that bugs me. Loops are ugly, but they are fast :) A straight code answer is fine, but I'd like to understand the logic needed for such a comparison as well. I'm probably going to have to implement said logic more than a few times down the road.

  • What else I must do allow my method to handle any type of objects

    - by NewHelpNeeder
    So to allow any type object I must use generics in my code. I have rewrote this method to do so, but then when I create an object, for example Milk, it won't let me pass it to my method. Ether there's something wrong with my generic revision, or Milk object I created is not good. How should I pass my object correctly and add it to linked list? This is a method that causes error when I insert an item: public void insertFirst(T dd) // insert at front of list { Link newLink = new Link(dd); // make new link if( isEmpty() ) // if empty list, last = newLink; // newLink <-- last else first.previous = newLink; // newLink <-- old first newLink.next = first; // newLink --> old first first = newLink; // first --> newLink } This is my class I try to insert into linked list: class Milk { String brand; double size; double price; Milk(String a, double b, double c) { brand = a; size = b; price = c; } } This is test method to insert the data: public static void main(String[] args) { // make a new list DoublyLinkedList theList = new DoublyLinkedList(); // this causes: // The method insertFirst(Comparable) in the type DoublyLinkedList is not applicable for the arguments (Milk) theList.insertFirst(new Milk("brand", 1, 2)); // insert at front theList.displayForward(); // display list forward theList.displayBackward(); // display list backward } // end main() } // end class DoublyLinkedApp Declarations: class Link<T extends Comparable<T>> {} class DoublyLinkedList<T extends Comparable<T>> {}
