• Can't SSH to remote server,how to avoid this

  - by snow8261

  From time to time,we suffer problems like we can not remote connect to our server via ssh.So we have to send someone on site to restart the computer for this problem.It causes a lot of pain.The situation is we have to remote connect to our server,which are very important like database server and application server and etc.We have met problems like ssh hang,like command ssh [email protected] with no response. when using ssh -v debug mode, it says : debug1: Connection established. debug1: identity file /.ssh/identity type -1 debug1: identity file /.ssh/id_rsa type -1 debug1: identity file /.ssh/id_dsa type -1 debug1: loaded 3 keys and we met this situation many times with no clue how to solve it.Is any log which can identify this problem? or Is there a tool for this problem? help needed!any idea are appreciated.

• How does COM registration work in Windows

  - by Air Benji

  I'm an application packager trying to make sense of how the COM registry keys (SelfReg) interrelate to the given .dll in Windows. ProgID's, AppID's, TypeLibs, Extensions & Verbs are all tied around the CLSID right? Do CLSID's always use Prog/App IDs or could you just have a file extension class? Which bits are optional? Some of it seems to be 'like a router' where there's the two interfaces (internal - .dll) and external (the extension etc). How does this all fit? (The SDK documentation doesn't make sense to me) I ask as this is all pivotal to application 'healing' with Windows Installer (which packagers are all 'big' on, but there's no nitty-gritty breakdowns since its a coder-thing really) ---Edit: Am I safe in assuming that for what COM is registered, it must all link back to the CLSID and cannot be a 'dead-end'? Verbs need extensions which need progid's... What about the AppId's, TypeLibs and Interfaces? How do they interrelate?

• Python: Getting INVALID response from PayPal's Sandbox IPN, slowly going insane...

  - by thepeanut

  Hi All I am trying to implement a simple online payment system using PayPal, however I have tried everything I know and am still getting an INVALID response. I know it's nothing too simple, because I get a VERIFIED response when using the IPN simulator. I have tried putting the items into a dict first, I have tried fixing the encoding, and still nothing. PayPal says the reasons for an INVALID response could be: Sending wrong items or in wrong order (pretty sure it's not this) Sending to the wrong address (definitely not this) Encoding items incorrectly (I dont think it's this, set encoding to UTF-8 on both paypal and my script) The following is the snippet concerned: f = cgi.FieldStorage() newparams = 'cmd=_notify-validate' for key in f.keys(): val = f[key].value newparams += '&' + urlencode({key: val.encode('utf-8')}) req = urllib2.Request(PP_URL, newparams) req.add_header("Content-type", "application/x-www-form-urlencoded") http = urllib2.urlopen(req) ret = http.read() fi.write(ret + '\n') if ret == 'VERIFIED': #*do stuff* Can anyone suggest anything I can do to fix this?! Cheers Sam

• how to localize a table with multiple text entries?

  - by rap-uvic

  Hello, I'm writing a web app which will allow creation of events. An event can have a title as well as a description amongst other things. The app needs to be multilingual. So I have 4 tables for localization: ResourceTypes, ResourceKeys, Resources, and Locales. A resource key can have multiple values in Resources table for different locales. So Resources is a many to many table between ResourceKeys and Locales. So in the event table I want to have a resourceKey for its title as well as a resourceKey for its description. So my question is, is it OK from database-design perspective to have two foreign keys from a table into another table? Has anybody used a better approach in such a scenario?

• GnuPG + Webservice + ASP.NET

  - by Karol Bladek

  Hi! I'm exhausted. I have installed GnuPG and exported secret key, and two public keys (my own and one of my client) from another instance of GnuPG. I try to configure 'my encrypting/decrypting' method on the local machine. When I run encrypting method from a little console application it works good. When I run this (same! - with the same body) method from my webservice on my local machine ... I have an ExitCode = 2. Happy in fact of catching the error message, but unhappy with their body. "gpg: no default secret key: secret key not available gpg: XXXXXXXXXXXXXXXX.xml: sign+encrypt failed: secret key not available" What should I do? Whats wrong? Best regards, Karol Bladek

• How do I test SendInput in c#

  - by JoelHess

  How can I tell if my call to SendInput is working properly? I have a small snippet below, and the message never seems to get hit. SendInput() returns 1, and there's no errors, so I assume that the message is going out properly. I've also tried the Form KeyPress and KeyDown Events, and I never seem to get those either. private void button1_Click(object sender, EventArgs e) { INPUT input = new INPUT(); input.mkhi.ki.wVk = (byte)System.Windows.Forms.Keys.B; uint result = SendInput(1, ref input, Marshal.SizeOf(new INPUT())); } protected override void WndProc(ref Message m) { if (m.Msg == WM_KEYDOWN) { Console.WriteLine("GotIt"); } base.WndProc(ref m); }

• IE8 Developer Tools won't open

  - by Dave

  Just installed IE8 on WinXP. Trying to use the Dev Tools but, clicking on the menu item or hitting F12 doesn't do anything. I can see the option in the tools menu, just can't use it. I've checked to make sure it wasn't opening minimized or off screen and I've checked the registry settings used to disable them. Those registry keys don't even exists. Suggestions? I was going to reinstall, but, thought I'd check here first.

• Java simple encryption

  - by Ran

  Hello, I would like to encrypt a textual (configuration) file stored on disk. Trying to use DES encryption I've had fatal error on client machines, I later found out caused because the algorithm could not handle accented characters (!) I suspect that was because I was using old packages (sun.misc.BASE64Decoder) - but I'm not sure that is the reason. However, I'm looking for a simpler solution - I need a really simple encryption (I know some people would not agree on that) - not RSA of 128 bit keys or so, just obscuring the text from curious eyes. It is really weird that I could not find on the web a simple trivial solution. Any idea, anyone ? Thanks, Ran

• Rails Foreign key setup question.

  - by James P. Wright

  I'm just (re)starting playing around with Rails and I'm making a little card game app. I cannot seem to figure out my Foreign Key setups. Say I have 4 objects: - Game - Player - Hand - Card A Game has many Players, which have many Hands which have many Cards. But the cards are also independent of a Hand, Player and Game. For example, I have 6 Cards in my database (1 to 6). It is possible that Card 3 could be in 2 Players Hands in the same Game. How can I set up my keys for this? Should I just create another object for "CardInHand" to simplify it?

• LINQ-To-SQL and Many-To-Many Relationship Deletions

  - by Jake

  I have a many-to-many relationship between two tables, let's say Friends and Foods. If a friend likes a food I stick a row into the FriendsFoods table, like this: ID Friend Food 1 'Tom' 'Pizza' FriendsFoods has a Primary Key 'ID', and two non-null foreign keys 'Friend' and 'Food' to the 'Friends' and 'Foods' tables, respectively. Now suppose I have a Friend tom .NET object corresponding to 'Tom', and Tom no longer likes pizza (what is wrong with him?) FriendsFoods ff = tom.FriendsFoods.Where(x => x.Food.Name == 'Pizza').Single(); tom.FriendsFoods.Remove(ff); pizza.FriendsFoods.Remove(ff); If I try to SubmitChanges() on the DataContext, I get an exception because it attempts to insert a null into the Friend and Food columns in the FriendsFoods table. I'm sure I can put together some kind of convoluted logic to track changes to the FriendsFoods table, intercept SubmitChanges() calls, etc to try and get this to work the way I want, but is there a nice, clean way to remove a Many-To-Many relationship with LINQ-To-SQL?

• Best Practise to populate Fact and Dimension Tables from Transactional Flat DB

  - by alex25

  Hi! I want to populate a star schema / cube in SSIS / SSAS. I prepared all my dimension tables and my fact table, primary keys etc. The source is a 'flat' (item level) table and my problem is now how to split it up and get it from one into the respective tables. I did a fair bit of googling but couldn't find a satisfying solution to the problem. One would imagine that this is a rather common problem/situation in BI development?! Thanks, alexl

• Load a Settings.settings into ListView?

  - by clefranc

  Hi, I've managed to save ListView items to a System.Collections.Specialized.StringCollection property settings using this LINQ one liner: My.Settings.Property1.AddRange(ListView1.Items.Cast(Of ListViewItem)().[Select](Function(a) String.Join(Convert.ToChar(Keys.Tab), a.SubItems.Cast(Of System.Windows.Forms.ListViewItem.ListViewSubItem)().[Select](Function(s) s.Text).ToArray())).ToArray()) Now, I want to do the opposite, ie load the ListView1 from the My.Settings.Property1. It's fairly easy to do using a For Each loop, but I wonder if someone can show me a similar LINQ query. The lines in My.Settings.Property1 looks like this (Tab separated): Word1 Word2 Word3 Word4 Word5 Word6 Original code is from this answer: http://stackoverflow.com/questions/2295068/show-listview-items-in-a-combobox

• Entity Framework - Using a lookup (picklist) table with a lookup key

  - by Dave

  I'm working on a WPF application that is working well using the Entity Framework (3.5 SP1) for complicated table structures. The problem now is I want to get a list from the EF that includes lookups into a picklist table that has multiple picklists in it. In SQL I would write a sub select as such: SELECT Name, (Select typeName from PickLists where type_id = items.type_id and picklist_key=333) as Type_desc FROM Items There are no Foreign keys for this, and the picklists table is never updated using the EF, so it is read only as far as the EF is concerned. I'm not sure the best method to put this into the model if at all. I'm displaying in a read-only datagrid on a dashboard. Thanks!

  - by riya

  Could someone write simple Perl programs for the following scenarios: convert a list from {1,2,3,4,5,7,9,10,11,12,34} to {1-5,7,9-12,34} to sort a list of negative numbers to insert values to hash array there is a file with content: C1 c2 c3 c4 r1 r2 r3 r4 put it into an hash array where keys = {c1,c2,c3,c4} and values = {r1,r2,r3,r4} There are testcases running each testcase runs as a process and has a process ID. The logs are logged in a logfile process ID appended to each line. Prog to find out if the test case has passed or failed. The program shoud be running till the processes are running and display output.

• batch file that detects keystrokes. how?

  - by daniel11

  im designing a collection of video games for the command line (such as deal or no deal, tic tac toe, racing, maze puzzle, connect four, wack a mole, etc.) however it would really make things easier for me if i could make it so that when the user makes a selection (such as what direction to move in the game) , that as soon as they press the arrow keys then it carries out the IF statements that follow. Instead of having to press enter after each selection. something like... :one1 set /p direction1= : IF %direction1%== {ARROW KEY LEFT} goto two2 IF %direction1%== {ARROW KEY RIGHT} goto three3 IF %direction1%== {ARROW KEY UP} goto four4 IF %direction1%== {ARROW KEY DOWN} goto five5 goto one1 Any Ideas?

• Django BigInteger auto-increment field as primary key?

  - by Alex Letoosh

  Hi all, I'm currently building a project which involves a lot of collective intelligence. Every user visiting the web site gets created a unique profile and their data is later used to calculate best matches for themselves and other users. By default, Django creates an INT(11) id field to handle models primary keys. I'm concerned with this being overflown very quickly (i.e. ~2.4b devices visiting the page without prior cookie set up). How can I change it to be represented as BIGINT in MySQL and long() inside Django itself? I've found I could do the following (http://docs.djangoproject.com/en/dev/ref/models/fields/#bigintegerfield): class MyProfile(models.Model): id = BigIntegerField(primary_key=True) But is there a way to make it autoincrement, like usual id fields? Additionally, can I make it unsigned so that I get more space to fill in? Thanks!

• NSMutableDictionary of NSMutableSets... sorting this out

  - by Mike

  I have a NSMutableDictionary of NSMutableSets. Each set entry is a string, something like this: NSMutableSet *mySet = [NSMutableSet setWithObjects: [NSString stringWithFormat:@"%d", time1], [NSString stringWithFormat:@"%d", time2], [NSString stringWithFormat:@"%d", time3], nil]; // time 1,2,3, are NSTimeInterval variables then I store each set on the dictionary using this: NSString *rightNowString = [NSString stringWithFormat:@"%d", rightNow]; [myDict setValue:mySet forKey:rightNow]; // rightNow is NSTimeInterval as rightNow key can occur out of order, I end with a NSDictionary that is not ordered by rightNow. How can I sort this NSDictionary by its keys considering that they are numbers stored as strings on the dictionary...? I don't care for ordering the sets, just the dictionary. thanks for any help.

• Hibernate - hibernate.hbm2ddl.auto = validate

  - by azp74

  I am interested in how hibernate.hbm2ddl.auto=validate actually works and I am struggling to find comprehensive documentation. We've recently discovered production system was affected by http://opensource.atlassian.com/projects/hibernate/browse/HHH-3532 (Hibernate matches foreign keys on name, rather than signature and so will recreate them for you) and hibernate.hbm2ddl.auto=update is being removed from our next release. I would be quite happy to just get rid of hibernate.hbm2ddl.auto altogether and manage our database ourselves. However, not all my colleagues share this world view and some are keen to add back in hibernate.hbm2ddl.auto=validate. I'm concerned this will hit the same problem and I'm interested in finding more documentation about how this validation actually works. The Hibernate Community Documentation (http://docs.jboss.org/hibernate/core/3.3/reference/en/html/session-configuration.html) really just makes reference to the values. Does anyone have any good documentation pointers, or any real life experience of using validate in a production system?

• How can I reprogram a USB "easy button"?

  - by Shawn Simon

  I have a USB "easy button"- is a USB cable attached to a large button. It appears as a keyboard to the computer. When I push the button, it sends the keys Start+R and then quickly types in a pre-configured URL. I am fairly certain that the company that produces these buttons sets the URL via some sort of software over USB. How could I reprogram the button myself? What sort of software would I need? Here is a link to the website: http://www.usbsmartbuttons.com/

• D3.js binding an object to data and appending for each key

  - by frshca

  I'm a D3.js newbie and I'm learning how to play around with data. Let's say I have an object with names as keys, and each key has an array of numbers like this: var userdata = { 'John' : [0, 1, 3, 9, 8, 7], 'Harry': [0, 10, 7, 1, 1, 11], 'Steve': [3, 1, 4, 4, 4, 17], 'Adam' : [4, 77, 2, 13, 11, 13] }; For each user, I would like to append an SVG object and then plot the line with the array of values for that user. So here is my assumption of how that would look based on tutorials, but I know it is incorrect. This is to show my limited knowledge and give better understanding of what I'm doing: First I should create the line var line = d3.svg.line().interpolate('basis'); Then I want to bind the data to my body and append an svg element for each key: d3.select('body') .selectAll('svg') .data(userdata) .enter() .append('svg') .append(line) .x(function(d, i) { return i; }) .y(function(d) { return d[i]; }); So am I close??

• PHP Key name array

  - by Sean McRaghty

  I have an array $data fruit => apple, seat => sofa, etc. I want to loop through so that each key becomes type_key[0]['value'] so eg type_fruit[0]['value'] => apple, type_seat[0]['value'] => sofa, and what I thought would do this, namely foreach ($data as $key => $value) { # Create a new, renamed, key. $array[str_replace("/(.+)/", "type_$1[0]['value']", $key)] = $value; # Destroy the old key/value pair unset($array[$key]); } print_r($array); Doesn't work. How can I make it work? Also, I want everything to be in the keys (not the values) to be lowercase: is there an easy way of doing this too? Thanks.

• Using info.plist for storing target-specific values for a multi-target app

  - by andybee

  I have a multi-target iPhone app which currently includes a header file with constant definitions that are conditionally included at build time depending on which target is being built. However, I was wondering if it might be better to instead include this information in the info.plist for the build, as this generally holds target-specific meta, so logically seems more appropriate. Therefore, my questions are: Is it acceptable to include custom (non-Apple defined) keys in the info.plist file? Is this a suitable place to include meta for the app which changes between targets?

• Database design: circular references

  - by SlappyTheFish

  I have three database tables: users emails invitations Emails are linked to users by a user_id field. Invitations are also linked to users by a user_id field Emails can be created without an invitation, but every invitation must have an email. I would like to link the emails and invitations tables so it is possible to find the email for a particular invitation. However this creates a circular reference, both an invitation and an email record hold the id for the same user. Is this bad design and if so, how could I improve it? My feeling is that with use of foreign keys and good business logic, it is fine.

• fluent nhibernate m-to-m with column

  - by csetzkorn

  Hi, I am used to hbm files and started using fluent nhibernate recently. Creating an m-to-m relationship between two entities A and B is quite simple In A I create: public virtual IList Bs { get; set; } and then I use: mapping.HasManyToMany(x = x.Bs); That’s it and I can do: A a = new A(); a.Bs.Add(b); My problem is that I would like to have an additional column in my dedicated m-to-m database table which holds the two foreign keys. What is the simplest way to achieve this in FNH? Would I have to create a dedicated entity for the m-to-m realtionship or is there a simpler solution? Thanks. Best wishes, Christian
