• Multiple public/private key pairs for the same user

  - by bruceb

  First, sorry if this question has already been asked/answered - I've searched but perhaps I haven't recognised the answer.... What we have is a cluster of servers which need to access a single remote server using sftp. We are migrating from one remote server to another at the same (remote) location. We also want to refresh the public/private key pairs on the configuration as part of an ongoing security review. My question is - can we have multiple public/private key pairs for the same user between server A and server B? I want to do this to allow for cutover testing - but am concerned that the software checking keys may only try one of each type (rsa/dsa?) before rejecting the connection method and moving to the next type of key. Hope it's a straightforward question - please let me know if I need to supply more details. Thanks in advance Bruce

• Getting the keyboard working on a MacBook under Windows XP x64

  - by Theran

  Despite Windows XP Professional x64's unsupported status on MacBooks (model A1181), I've managed to get most of the hardware working by manually installing either the drivers on the OS X Snow Leopard CD, or finding the appropriate drivers online. However, even after installing the Apple keyboard driver from the CD, I can't get Windows to actually use the special driver. Instead, the keyboard just shows up as a generic USB keyboard, with non-functioning Fn and other special keys. Being unable to generate a right-click or Ctrl-Alt-Del makes Windows a bit of a challenge to use. I've tried: uninstalling and reinstalling the keyboard driver removing the keyboard under device manager and letting Windows re-detect it using device manager to manually update the driver How do I get the special functions of the MacBook keyboard working under XP x64?

• A better understanding of the relations beetween database tables

  - by Nistor Alexandru

  Hi I am trying to get a better understanding of relational databases and there is something that I keep bumping into and don't understand.Let's take this two tables: In this case Login.ID is the primary key with auto_increment set and Profile.ID_LOGIN is the Foreign KEY.When a user is created and it's username and password is stored in the login database does the ID coresponding to the curesnt username and password get automaticly added into ID_LOGIN or do I have to create an SQL statement to do this? If I have to create a SQL statement how should I aproach adding the ID_LOGIN to make sure I am adding it corectly?

• How to enter Devanagari half-R character in Emacs MULE?

  - by journeyer

  I am trying the Emacs MULE ITRANS input method to enter Devanagari unicode text. I am looking to enter a key sequence for Devanagari letter "Half-R" (??) i.e. U0931 U094d (which should be mapped to R according to the ITRANS Wikipedia page). While all other keys in the map work fine, this particular one does not! I know I can use M-x ucs-insert (or CTRL-x-8 RET) to enter this sequence, but it is getting tiresome. How do I fix this problem ?

• User HasOne ActiveToken, HasMany Tokens, how to setup in Rails?

  - by viatropos

  I have two simple models: class User < ActiveRecord::Base has_many :tokens # has_one doesn't work, because Token already stores # foreign id to user... # has_one :active_token, :class_name => "Token" # belongs_to doesn't work because Token belongs to # User already, and they both can't belong to each other # belongs_to :active_token, :class_name => "Token" end class Token < ActiveRecord::Base belongs_to :user end I want to say "User has_one :active_token, :class_name => 'Token'", but I can't because Token already belongs_to User. What I did instead was just manually add similar functionality to the user like so: class User < ActiveRecord::Base has_many :tokens attr_accessor :active_token after_create :save_active_token before_destroy :destroy_active_token # it belongs_to, but you can't have both belongs_to each other... def active_token return nil unless self.active_token_id @active_token ||= Token.find(self.active_token_id) end def active_token=(value) self.active_token_id = value.id @active_token = value end def save_active_token self.active_token.user = self self.active_token.save end def destroy_active_token self.active_token.destroy if self.active_token end end Is there a better way?

• How can one make the title bar text have better contrast on dark colors in Windows 8?

  - by zeel

  When Windows 8 color setting are set to a very dark color, such as black or navy blue, the title bar text and the minimize/maximize buttons are nearly invisible. This makes dark colors difficult to work with. In Windows 7 there was an advanced color options, this is gone in 8. The registry keys associated with this seem to still be present, but they have no effect. Is there a way to change this? Or a third party application that can do it? I don't want to use the ugly high contrast theme, I want to use the nice Win 8 theme with a dark color.

• Sqlalchemy: Many to Many relationship error

  - by 1001010101

  Dear everyone, I am following the Many to many relationship described on http://www.sqlalchemy.org/docs/mappers.html#many-to-many #This is actually a VIEW tb_mapping_uGroups_uProducts = Table( 'mapping_uGroups_uProducts', metadata, Column('upID', Integer, ForeignKey('uProductsInfo.upID')), Column('ugID', Integer, ForeignKey('uGroupsInfo.ugID')) ) tb_uProducts = Table( 'uProductsInfo', metadata, Column('upID', Integer, primary_key=True) ) mapper( UnifiedProduct, tb_uProducts) tb_uGroupsInfo = Table( 'uGroupsInfo', metadata, Column('ugID', Integer, primary_key=True) ) mapper( UnifiedGroup, tb_uGroupsInfo, properties={ 'unifiedProducts': relation(UnifiedProduct, secondary=tb_mapping_uGroups_uProducts, backref="unifiedGroups") }) where the relationship between uProduct and uGroup are N:M. When I run the following sess.query(UnifiedProduct).join(UnifiedGroup).distinct()[:10] I am getting the error: sqlalchemy.exc.ArgumentError: Can't find any foreign key relationships between 'uProductsInfo' and 'uGroupsInfo' What am I doing wrong?

• Set to null a parent record so that children are removed: howto?

  - by EugeneP

  How to delete a child row (on delete cascade ?) when setting a null value on a parent? Here's the db design. table A [id, b_id_1, b_id_2] table B [id, other fields...] b_id_1 and b_id_2 can be NULL if any of them is null, it means NO B records for corresponding FK (there are 2 of them) so (b_id_1,b_id_2) can be (null,null), (100, null), (null, 100_or_any_other_number) etc How in one SQL query both set b_id_1 or b_id_2 to null and delete all rows from B that have this id? What FK design should be applied to the 2 tables? what foreign keys should be added? A - B (FK_1: A.b_id_1 references B.id, FK_2: A.b_id_2 references B.id) and also B-A (FK_3: B.id references A.b_id_1, FK_4: B.id references A.b_id_2) ? But again, setting an A's b_id_1 or A's b_id_2 to null - will it remove any of B's records? I don't think so. So how to do that?

• Update 2 table values in one query in LINQ

  - by fireBand

  Hello, I have 2 tables Table1 with columns [BId,Name,Amount] Table2 with columns [CId,BId, ExpenseType,Expense]. BId Is the foreign key in Table2. The Amount field in Table1 is always higher than Expense in Table2. I need to update the values of Amount (increase or decrease) based on value of Expense and I want to do it in single query in LINQ. Eg If the Expense has to be updated with 200, I would decrease(negate) Amount value with 200. If Expense is reduce to 100 then the Amount is increased by a value of 100. Thanks in advance for any suggestions.

• How to call javascript function when url variable is sent

  - by mattlarkin

  Hello, heres basically what I need to get done. I have a jsp page which allows me to add/modify/delete an item. The items are stored in a database which I have controller classes to access(dont worry bout that part) When an item gets selected and deleted the id of the item gets sent to the controller to be processed. The item will not always be deleted if their is a foreign key constraint so I send either a delete=true or delete=false through url back to the jsp page. I would like to have it so a javascript function gets called displaying an alert saying the item was deleted or the item was not deleted. can someone please tell me the best way to do this? thank you

• Making a many-to-many relationship using DataRelations object

  - by dotnetdev

  Hi, I have about 200 tables which need to relate to another table in a many-to-many fashion. I have the tables (including the intersection table) ready IN SQL Server. How can I write code using the data relation object to make the relationship? The tables are: PartStatPartName PartsMaterialsIntersection << Materials The materials table needs to have a foreign key from the PartStatPartName table. I tried various approaches using the DataRelation class but the change did not sync to SQL Server, despite being connected and adding the relation, and then calling AcceptChanges() on the dataset. Any guidance much appreciated. I have seen some threads covering the same problem but need an example in code so I can follow the right method. Thanks

• The authenticity of host “host” can't be established

  - by Candroid

  I'm running a web app on a Linux server which connects to other servers. When I run the project on my Play framework on loclhost it runs fluently. When I run it on my Linux server I get the above message 3 times, one for each server. I read a post about it where it says that it is a man in the middle warning and if I write yes it should work. But though a write yes, nothing happens and the app doesn't run, and the error message keeps popping up. I tried creating private and public keys and add them to the authorized_keys file, but it didn't work either. What should I so to run my app?

• Table naming convention?

  - by MattSlay

  In our manufacturing shop, each Employee hits the time clock every time they change Jobs or Machines (work centers) during their work day. Each record created in the Time Clock app has foreign keys that link the record to: the Employee, the Job, and the Machine which they are about to operate. I’m trying to determine the best name for this table… If I were tempted to call it ClockRecords or TimeClockRecords, why wouldn’t I also consider naming it JobTimeRecords, or why not MachineTimeRecords. Any ideas on a good name?

• Run init.d script in the context of the current user session.

  - by akellehe

  I'd like to run a script in init.d (on Fedora) in the context of the user session I'm logging in as. I have a script called keyboard_deadkeys I wrote to set some deadkeys on my keyboard. The script is very simple: #!/bin/bash /usr/bin/xmodmap /home/julie/keymappings I put it in the directory /etc/init.d so it will run at boot time. It is also in /etc/rc.d/init.d I changed the permissions to a+rwx for good measure. When I boot; the deadkeys aren't set in the user's session. When I then run the script manually; the keys are set. How can I rectify this?

• How to move a Windows instance to a different EC2 data centre?

  - by Darren Cook

  I've a Windows EC2 instance running in one region and need to move it to another region (Tokyo and Singapore in this case). Is that even possible? What potential problems do I need to watch out for? (I found http://stackoverflow.com/questions/2181849/ec2-instance-cloning which is describing how to do it, but appears to assume Linux instances, and to assume the same data centre. Is it possible to move my keys across to another region?) I tried something similar with a Windows instance a few months ago, just trying to clone it in the same data centre, but I couldn't get it working quickly, so I had to give up and just create a fresh instance at that time. This time I've got a bit of breathing space, and want to research how to do it properly! Root Device Type: ebs Block Devices: sda1 xvdf (both are ebs, "attached", and have Delete on termination set to "no"; sda1 is the root device) The AMI is described as "Unavailable" (then an ami number).

• Microsoft word 2003 when I am making deletions or changes they show up on the document in a balloon

  - by Cyberdude

  I am writing a novel in microsoft word 2003, and I am pretty far into it, but one time I hit a one of the F keys (I don't know which one) by accident. Now everytime I go on word I have these stupid balloons with writing in them and all my deletions and everything are highlighted shown. I looked up on google how to stop this and I did as it says, and it worked the balloon with the deletions and all the changes dissapeared, but next time I opened up the document they were back, and they always keep coming back, so when I send my document to anyone it shows them all my deletions and changes I made to the document. Can anyone help please. Thanks

• Is there a tool that will show diagrams of my SQL database in real-time?

  - by Rising Star

  I've created some diagrams of SQL tables using the "Reverse Engineer" feature of Microsoft Office Visio. I like being able to visualize my relational databases in this manner. However, what I get is just a static document that I can print, e-mail to colleagues, and click widgets on. Earlier this year, I saw at a demo that the new version of Visual Studio 2010 has a new feature called the "Architect Explorer", which allows developers to view relationships among .net classes on the fly. It has many features for filtering the data that the developer is interested in. It would be really awesome if I could visually browse my tables and stored procedures and see what is related to what by primary key, foreign key, and referenced in stored procedures. I realize that I'm talking about two entirely different technologies and it's not a perfect analogy, but is there some similar tool that would allow me to visualize tables in my SQL database?

• How does Office 2008 for Mac store its Recent items?

  - by zenopolis

  I don't have access to Office 2008, but require the information for a project I'm working on. I'm mainly interested in Word, Excel and Powerpoint. This is the information I have gathered so far... The preference file is: ~/Library/Preferences/com.microsoft.office.plist The property keys take the form: 2008\File Aliases\{APP}{n} 2008\MRU Access Date\{APP}{n} where {APP} represents an Office application, and {n} represents a number starting from 0. The applications are represented by the following values: MSWD (Word) XCEL (Excel) What value represents PowerPoint? In the property list I've seen, the numbers represented by {n} range from 0-10 (11 items). Is 10 the limit? or is this unrestrained? Finally, I've noticed that Office 2011 does not add its Recent Items to the Apple System menu: Apple > Recent Items Is Office 2008 the same?

• Android: Maps - Best way to provide 'search for location' feature?

  - by r3mo

  Hello all, I've got an android app that uses a map activity and serves up content based on map location. I'm looking for a way to allow the user to search for a location by name (anything from 'New York' to 'Eiffel Tower') - e.g. have a text input field into which they could type 'Rome' - after pressing a button, the user would be brought to the coordinates of Rome on the map. What would be the best way to go about this? I've looked into the google geocoding api (http://code.google.com/apis/maps/documentation/geocoding/), but it has limitations of 2,500 geolocation requests per day - I'm presuming this is per API key? Or is it per user/source IP? 2,500 requests for one android app woudln't last long. Ideally, I would be able to search for English and foreign names of countries. Thanks in advance! r3mo

• what are the following keyboard shortcuts in a terminal?

  - by kloop

  I am trying to figure out a few keyboard shortcuts in a terminal in mac osx (and Linux): In the command line: go to the next word go to the previous word go to the end of the line go to the beginning of the line This will make it easier to change commands.. Right now, I am using the left/right arrow keys, which is time consuming. I used bind -p as suggested below. EDIT: What do the following key bindings mean? "\e\e[D": backward-word "\e[1;5D": backward-word "\e[5D": backward-word "\eb": backward-word and: "\e\e[C": forward-word "\e[1;5C": forward-word "\e[5C": forward-word "\ef": forward-word

• Django admin panel doesn't work after modify default user model.

  - by damienix

  I was trying to extend user profile. I founded a few solutions, but the most recommended was to create new user class containing foreign key to original django.contrib.auth.models.User class. I did it with this so i have in models.py: class UserProfile(models.Model): user = models.ForeignKey(User, unique=True) website_url = models.URLField(verify_exists=False) and in my admin.py from django.contrib import admin from someapp.models import * from django.contrib.auth.admin import UserAdmin # Define an inline admin descriptor for UserProfile model class UserProfileInline(admin.TabularInline): model = UserProfile fk_name = 'user' max_num = 1 # Define a new UserAdmin class class MyUserAdmin(UserAdmin): inlines = [UserProfileInline, ] # Re-register UserAdmin admin.site.unregister(User) admin.site.register(User, MyUserAdmin) And now when I'm trying to create/edit user in admin panel i have an error: "Unknown column 'content_userprofile.id' in 'field list'" where content is my appname. I was trying to add line AUTH_PROFILE_MODULE = 'content.UserProfile' to my settings.py but with no effect. How to tell panel admin to know how to correctly display fields in user form?

• Whats wrong with my keyboard?

  - by Neifen

  I have a new kind of weird problem with my laptops keyboard. To be precise with the shift key. Lately the both Shift-Keys doesn't just make the letters big, they also took role of the 2 and the 7 on the numpad. So when i push the left shift key (with num lock) it also writes a 7. When I use the left shift key (without num lock), the cursor goes to the begin of the line. When i push the right shift key (with num lock) it writes a 2. When I use the right shift key (without num lock), the cursor goes to the end of the line. I really don't know what I changed on the computer... it's really weird and really annoying

• Tallying records using annotate() not working as should.

  - by 47

  I have two classes: Vehicle and Issues....a Vehicle object can have several issues recorded in the Issues class. What I want to do is to have a list of all issues, with each vehicle appearing only once and the total number of issues shown, plus other details....clicking on the record will then take the user to another page with all those issues for a selected vehicle shown in detail now. I tried this out using annotate, but I could only access the count and vehicle foreign key, but none of the other fields in the Vehicle class. class Issues(models.Model): vehicle = models.ForeignKey(Vehicle) description = models.CharField('Issue Description', max_length=30,) type = models.CharField(max_length=10, default='Other') status = models.CharField(max_length=12, default='Pending') priority = models.IntegerField(default='8', editable=False) date_time_added = models.DateTimeField(default=datetime.today, editable=False) last_updated = models.DateTimeField(default=datetime.today, editable=False) def __unicode__(self): return self.description The code I was using to annotate is: issues = Issues.objects.all().values('vehicle').annotate(count=Count('id')) What could be the problem?
