  • Global Adopt a JSR Program Update

    - by heathervc
    The Global Adopt a JSR program, combining efforts of SouJava and London Java Community,  is an excellent place to get some Java User Group (JUG) resources for JSRs.  It also has the potential to act as an extra set of eyes, ears and volunteers for JSRs. The Global project to go to is at: http://adoptajsr.java.net.  The wiki page explaining the whole program and benefits to Spec Leads and EG's can be found there, including: The mailing list: [email protected] . Portugese speakers-mainly Brazlian JUG members-have their own mailing list and more language lists may be added as required. The IRC channel is at adoptajsr on irc.freenode.net Also check out this InfoQ article with Martijn Verburg about the London Java user group, the Adopt a JSR program, the JCP and Oracle’s handling of the Java community.

  • Where is the best and easiest place to store global website settings [migrated]

    - by Darkcat Studios
    I'm just putting together an internal data system for a client, which is ASP.NET VB, backed by an SQL database, on an in-house IIS7.5 dedicated server. I want to store certain global settings, such as the age limit for news articles, admin contacts etc, in a file NOT within the database (i.e. to avoid unnecessary database query's) Where would the best place to store this be? global.asax? app.config? or a custom XML file? how would i import these at runtime? (probably to session variables) ETA: Also - the settings must be editable from within the site, i.e. an admin section i'm yet to build

  • Hibernate Query for a List of Objects that matches a List of Objects' ids

    - by sal
    Given a classes Foo, Bar which have hibernate mappings to tables Foo, A, B and C public class Foo { Integer aid; Integer bid; Integer cid; ...; } public class Bar { A a; B b; C c; ...; } I build a List fooList of an arbitrary size and I would like to use hibernate to fetch List where the resulting list will look something like this: Bar[1] = [X1,Y2,ZA,...] Bar[2] = [X1,Y2,ZB,...] Bar[3] = [X1,Y2,ZC,...] Bar[4] = [X1,Y3,ZD,...] Bar[5] = [X2,Y4,ZE,...] Bar[6] = [X2,Y4,ZF,...] Bar[7] = [X2,Y5,ZG,...] Bar[8] = ... Where each Xi, Yi and Zi represents a unique object. I know I can iterate fooList and fetch each List and call barList.addAll(...) to build the result list with something like this: List<bar> barList.addAll(s.createQuery("from Bar bar where bar.aid = :aid and ... ") .setEntity("aid", foo.getAid()) .setEntity("bid", foo.getBid()) .setEntity("cid", foo.getCid()) .list(); ); Is there any easier way, ideally one that makes better use of hibernate and make a minimal number of database calls? Am I missing something? Is hibernate not the right tool for this?

  • Static IPv6 address in Windows unused for outgoing connections

    - by Luc
    I'm running a Windows server and trying to get it to use a static IPv6 address for outgoing connections to other IPv6 hosts (such as Gmail). I need this because Gmail requires a ptr record, and I can't set one for random addresses. The static address is configured on the host, but it also has a temporary privacy address as well as a random address from the router it seems. By default Windows uses the privacy address; it seems this is the expected behavior (and it makes perfect sense for people/users that did not set a static address, but I did!). I've tried disabling the privacy address with: netsh int ipv6 set privacy disabled This indeed gets rid of the privacy address, but I still have the random address that the router assigned. To disable this, it was said I needed to disable "router discovery" using this command: net interface ipv6 set interface 14 routerdiscovery=disabled Upon doing this, all IPv6 connectivity is lost. If I do this while pinging Gmail, it will report "Destination host unreachable" as soon as I enter the command. In the static IPv6 configuration, I did configure the default gateway and prefix length, so I don't see why it's unable to connect. Probably has something to do with the lack of ARP in IPv6 and somehow being unable to resolve the router's MAC, but I wouldn't know how to fix this. Finally I've tried disabling the DHCPv6 lease with these commands: netsh interface ipv6 set interface "IDMZ Team" managedaddress=disabled netsh interface ipv6 set interface "IDMZ Team" otherstateful=disabled Which was to no avail; the host continues to obtain and use the router-assigned IPv6 address. The router is a FritzBox 7340, which shows me all the IPv4 and IPv6 addresses that the host (identified by MAC) utilizes, but I'm unable to change the assigned address. Maybe this could be done over the telnet interface of the router somehow, but again, I wouldn't know how to do this even if it's the way to go. In short, any of the following would probably solve my problem: Change Windows' source address selection behavior. Have Windows not get an address from the router and not generate a privacy address; Have the router hand out a static address and make Windows use that as source address. Recover connectivity after disabling router discovery on Windows. Alternatively I might use some (batch, perl, ...) script to throw away all IPv6 addresses except the desired one, but this feels rather hacky. If it's the only way (or less hacky than another hacky solution), it might be an option though. Thanks!

  • Address Match Key Algorithm

    - by sestocker
    I have a list of addresses in two separate tables that are slightly off that I need to be able to match. For example, the same address can be entered in multiple ways: 110 Test St 110 Test St. 110 Test Street Although simple, you can imagine the situation in more complex scenerios. I am trying to develop a simple algorithm that will be able to match the above addresses as a key. For example. the key might be "11TEST" - first two of 110, first two of Test and first two of street variant. A full match key would also include first 5 of the zipcode as well so in the above example, the full key might look like "11TEST44680". I am looking for ideas for an effective algorithm or resources I can look at for considerations when developing this. Any ideas can be pseudo code or in your language of choice. We are only concerned with US addresses. In fact, we are only looking at addresses from 250 zip codes from Ohio and Michigan. We also do not have access to any postal software although would be open to ideas for cost effective solutions (it would essentially be a one time use). Please be mindful that this is an initial dump of data from a government source so suggestions of how users can clean it are helpful as I build out the application but I would love to have the best initial I possibly can by being able to match addresses as best as possible.

  • Are there any useful tools to mirror a mailman mailing list as a forum?

    - by mar10
    We have a mailman mailing list however as we all know this is not very user friendly in terms of searching the archives. I am looking at a way to enable the continued functionality of mailman while having a forum linked to it for a more friendly user-interface approach. Is there a forum application that lets you mirror the mailman service so that posts to mailman are sync'd into the forum and posts to the forum are sync'd to mailman?

  • Calculate directed broadcast address given IP address and subnet in PowerShell

    - by halr9000
    My goal is to calculate the directed broadcast address when given the IP and subnet mask of a host node. I know, sounds like homework. Once I reasoned through my task and boiled it down to this, I was amused with myself. Anyway, the solution will look something like the one in this question I suppose, but I'm not a math major and my C sucks. I could do with a PowerShell (preferred) or C# example to get me going. thanks!

  • Return Selected Phone Address from iPhone Address Book

    - by Ali
    Hey, I found a tutorial online that extends that Apple QuickStart Application which is the basic Address Book Application and another that returns the first phone number regardless of what phone number was clicked. I want to display only the selected phone number in the label. The label is called phoneNumber: - (BOOL)peoplePickerNavigationController: (ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier{ ABMutableMultiValueRef phoneMulti = ABRecordCopyValue(person, kABPersonPhoneProperty); NSMutableArray *phones = [[NSMutableArray alloc] init]; int i; for (i = 0; i < ABMultiValueGetCount(phoneMulti); i++) { NSString *aPhone = [(NSString*)ABMultiValueCopyValueAtIndex(phoneMulti, i)autorelease]; [phones addObject:aPhone]; } NSString *mobileNo = [phones objectAtIndex:0]; self.phoneNumber.text = phones; [self dismissModalViewControllerAnimated:YES]; return NO; } How do I ensure that the label is the one selected by the user and not just the first array entry(or any other array entry i code in) Thanks

  • 1000Base-X layer 2/MAC address details

    - by user69971
    A layer 2 Ethernet frame is sent with a source and destination MAC address. Given a 100Base-TX (copper) trunk between two Cisco switches, I can do a "show interface fa 0/0" on S1 to see the MAC address assigned to the trunking interface, then go to Switch2 and do a "show mac address-table" and find the MAC address of the S1 fa 0/0 interface as a dynamically learned MAC in the table. Given a similar setup with a 1000Base-X (fiber GBIC) trunk, the MAC address shown in "show interface gi 0/0" on S1 does not show up in the MAC address-table of S2. Everything I can find online indicates that 1000Base-X uses largely the same layer 2 format as copper connections. There's some slight alterations - minimum frame size is slightly larger - but the fundamentals of the frame structure appear to be the same, including transmission with a source and destination L2 address. Why doesn't the address of gi 0/0 show up in the MAC address table of the connection switch? The only thing which seems to make sense would be that the GBIC has its own MAC address, almost as if its acting as a mini 2-port switch or hub, with the switch-assigned MAC address showing up on the interface connection and a different MAC address assigned to the fiber side. If this is the case, is there any way to see the GBIC MAC address on the switch? (I've tried to look up the details in IEEE 802.3z but it doesn't seem to be available without an IEEE membership or purchasing the standard. I find the base 802.3 PDFs for download, but not 802.3z.)

  • Procmail Mailing List (With Access Control)

    - by bradlis7
    This seems like it should be fairly easy to do, but I've run into a few problems. I've added a cron job to parse all users whose UID is greater than 5000: * * * * * root /usr/bin/test /etc/passwd -nt ~allusers/.forward \ && /bin/egrep '([5-9]|[0-9]{2})[0-9]{3}' /etc/passwd | /bin/grep -v 65534 \ | /bin/cut -d ':' -f 1 > ~allusers/.forward Then I created a .procmailrc file: VERBOSE=yes LOGFILE=/var/log/procmailrc #Allow only certain users to send :0 * ^From.*[email protected].* {} :0E /dev/null But, the .forward file is processed before it even gets to procmail, evidently. If I moved the .forward file to another filename, can I use it in procmail to send an email to the users in this file?

I don't understand why its showing a capacity of 8, when I only added 7 items.

  • LIST<> AddRange throwing ArgumentException

    - by Tim
    Hi all, I have a particular method that is occasionally crashing with an ArgumentException: Destination array was not long enough. Check destIndex and length, and the array's lower bounds.: at System.Array.Copy(Array sourceArray, Int32 sourceIndex, Array destinationArray, Int32 destinationIndex, Int32 length, Boolean reliable) at System.Collections.Generic.List`1.CopyTo(T[] array, Int32 arrayIndex) at System.Collections.Generic.List`1.InsertRange(Int32 index, IEnumerable`1 collection) at System.Collections.Generic.List`1.AddRange(IEnumerable`1 collection) The code that is causing this crash looks something like this: List<MyType> objects = new List<MyType>(100); objects = FindObjects(someParam); objects.AddRange(FindObjects(someOtherParam); According to MSDN, List<.AddRange() should automatically resize itself as needed: If the new Count (the current Count plus the size of the collection) will be greater than Capacity, the capacity of the List<(Of <(T)) is increased by automatically reallocating the internal array to accommodate the new elements, and the existing elements are copied to the new array before the new elements are added. Can someone think of a circumstance in which AddRange could throw this type of exception?

  • Advanced Python list comprehension

    - by Yuval A
    Given two lists: chars = ['ab', 'bc', 'ca'] words = ['abc', 'bca', 'dac', 'dbc', 'cba'] how can you use list comprehensions to generate a filtered list of words by the following condition: given that each word is of length n and chars is of length n as well, the filtered list should include only words that each i-th character is in the i string in words. In this case, we should get ['abc', 'bca'] as a result. (If this looks familiar to anyone, this was one of the questions in the previous Google code jam)

  • Python: Slicing a list into n nearly-equal-length partitions

    - by Drew
    I'm looking for a fast, clean, pythonic way to divide a list into exactly n nearly-equal partitions. partition([1,2,3,4,5],5)->[[1],[2],[3],[4],[5]] partition([1,2,3,4,5],2)->[[1,2],[3,4,5]] (or [[1,2,3],[4,5]]) partition([1,2,3,4,5],3)->[[1,2],[3,4],[5]] (there are other ways to slice this one too) There are several answers in here http://stackoverflow.com/questions/1335392/iteration-over-list-slices that run very close to what I want, except they are focused on the size of the list, and I care about the number of the lists (some of them also pad with None). These are trivially converted, obviously, but I'm looking for a best practice. Similarly, people have pointed out great solutions here http://stackoverflow.com/questions/312443/how-do-you-split-a-list-into-evenly-sized-chunks-in-python for a very similar problem, but I'm more interested in the number of partitions than the specific size, as long as it's within 1. Again, this is trivially convertible, but I'm looking for a best practice.

  • Equals method of System.Collections.Generic.List<T>...?

    - by Sambo
    I'm creating a class that derives from List... public class MyList : List<MyListItem> {} I've overridden Equals of MyListItem... public override bool Equals(object obj) { MyListItem li = obj as MyListItem; return (ID == li.ID); // ID is a property of MyListItem } I would like to have an Equals method in the MyList object too which will compare each item in the list, calling Equals() on each MyListItem object. It would be nice to simply call... MyList l1 = new MyList() { new MyListItem(1), new MyListItem(2) }; MyList l2 = new MyList() { new MyListItem(1), new MyListItem(2) }; if (l1 == l2) { ... } ...and have the comparisons of the list done by value. What's the best way...?

  • List problem in Reporting Services 2005

    Hi, I have a problem with a list in srss 2005. The list is grouping too much information and I dont know how to un-group it. I made a picture to show it. But because I'm new, I can only show it with this link: http://img32.imageshack.us/img32/6058/listproblem.gif So the list is also grouping the weeks, but that is not what I would like. Does anyone know how to change this? (in the designer view) Thanks in advance, Kris

  • F# Active Pattern List.filter or equivalent

    - by akaphenom
    I have a records of types type tradeLeg = { id : int ; tradeId : int ; legActivity : LegActivityType ; actedOn : DateTime ; estimates : legComponents ; entryType : ShareOrDollarBased ; confirmedPrice: DollarsPerShare option; actuals : legComponents option ; type trade = { id : int ; securityId : int ; ricCode : string ; tradeActivity : TradeType ; enteredOn : DateTime ; closedOn : DateTime ; tradeLegs : tradeLeg list ; } Obviously the tradeLegs are a type off of a trade. A leg may be settled or unsettled (or unsettled but price confirmed) - thus I have defined the active pattern: let (|LegIsSettled|LegIsConfirmed|LegIsUnsettled|) (l: tradeLeg) = if Helper.exists l.actuals then LegIsSettled elif Helper.exists l.confirmedPrice then LegIsConfirmed else LegIsUnsettled and then to determine if a trade is settled (based on all legs matching LegIsSettled pattern: let (|TradeIsSettled|TradeIsUnsettled|) (t: trade) = if List.exists ( fun l -> match l with | LegIsSettled -> false | _ -> true) t.tradeLegs then TradeIsSettled else TradeIsUnsettled I can see some advantages of this use of active patterns, however i would think there is a more efficient way to see if any item of a list either matches (or doesn't) an actie pattern without having to write a lambda expression specifically for it, and using List.exist. Question is two fold: is there a more concise way to express this? is there a way to abstract the functionality / expression (fun l - match l with | LegIsSettled - false | _ - true) Such that let itemMatchesPattern pattern item = match item with | pattern -> true | _ -> false such I could write (as I am reusing this design-pattern): let curriedItemMatchesPattern = itemMatchesPattern LegIsSettled if List.exists curriedItemMatchesPattern t.tradeLegs then TradeIsSettled else TradeIsUnsettled Thoughts?

  • Racket: change dotted pair to list

    - by user2963128
    I have a program that recursively calls a hashtable and prints out data from it. Unfortunately my hashtable seems to be saving data as dotted pairs so when I call the hashtable I get an error saying that there is no data for it because its tryign to search the hashtable for a dotted pair instead of a list. Is there an easy way to make the dotted pair into a regular list? IE im getting '("was" . "beginning") instead of '("was" "beginning") Is there a way to change this without re-writing how my hashtable store stuff? im using the let function to set a variable to this and then calling another function based on this variable (let ((data ( list-ref(hash-ref Ngram-table key) (random (length (hash-ref Ngram-table key)))))) is there a way to make the value stored in data just a list like this '("var1" "var2") instead of a dotted pair? edit: im getting dotted pairs because im using let to set data to the part of the hashtable's key and one of the elements in that hash.
