  • Make a connection to a HTTPS server from Java and ignore the validity of the security certificate

    - by justinhj
    I've been testing some that works with a bunch of https servers with different keys, some of which are invalid and all of them are not in the local key store for my JVM. I am really only testing things out, so I don't care about the security at this stage. Is there a good way to make POST calls to the server and tell Java not to worry about the security certificates? My google searches for this have brought up some code examples that make a class to do the validation, that always works, but I cannot get it to connect to any of the servers.

  • sql locking on silverlight app

    - by immuner
    Hi, i am not sure if this is the correct term, but this is what id like to do: I have an application that uses a mssql database. This application can operate in 3 modes. mode 1) user does not alter, but only read the database mode 2) user can add rows (one at a time) onto a table in the database mode 3) user can alter several tables in the database (one person at a time) question 1) how can i ensure that when a user in in mode 3 that the database will "lock" and all logged in users who operate in mode 2 or mode 3 will not be able to change the database until he finishes? question 2) how can i ensure that while there are several users in mode 2, that there will be no conflict while they all update the table? my guess here, is that before adding a new row, you make a server query for the table's current unique keys and add the new entry. will this be safe enough though? Thanks

  • Windows 7 sharing data between users via the registry

    - by r99
    Where can I create/modify/delete registry keys to share data between users in the Windows 7 registry? Both of the users are non administrators and it shouldn't require admin privileges. The application I'm working on uses the registry to write a key from userA and then userB can read/modify/delete it. Neither user has admin privileges and it won't be possible to change this. Is there an official MSDN guide to how to use the registry in Windows 7? Any links describing proper use of the registry would be useful.

  • C++: A variation of priority queue

    - by Helltone
    I need some kind of priority queue to store pairs <key, value>. Values are unique, but keys aren't. I will be performing the following operations (most common first): random insertion; retrieving (and removing) all elements with the least key. random removal (by value); I can't use std::priority_queue because it only supports removing the head. For now, I'm using an unsorted std::list. Insertion is performed by just pushing new elements to the back (O(1)). Operation 2 sorts the list with std::sort (O(N*logN)), before performing the actual retrieval. Removal, however, is O(n), which is a bit expensive. Any idea of a better data structure?

  • MySQL primary/foreign key size?

    - by David
    I seem to see a lot of people arbitrarily assigning large sizes to primary/foreign key fields in their MySQL schemas, such as INT(11) and even BIGINT(20) as WordPress uses. Now correct me if I'm wrong, but even an INT(4) would support (unsigned) values up to over 4 billion. Change it to INT(5) and you allow for values up to a quadrillion, which is more than you would ever need, unless possibly you're storing geodata at NASA/Google, which I'm sure most of us aren't. Is there a reason people use such large sizes for their primary keys? Seems like a waste to me...

  • KRL and Yahoo Local Search

[object Object] and 'title' has {'$t' => 'Pizza Shop 1'} I can't figure out how to get just the title.

  • Getting ssh to execute a command in the background on target machine

    - by dagorym
    This is a follow-on question to the How do you use ssh in a shell script? question. If I want to execute a command on the remote machine that runs in the background on that machine, how do I get the ssh command to return? When I try to just include the ampersand (&) at the end of the command it just hangs. The exact form of the command looks like this: ssh user@target "cd /some/directory; program-to-execute &" Any ideas? One thing to note is that logins to the the target machine always produce a text banner and I have ssh keys set up so no password is required.

  • Perl Hash Slice, Replication x Operator, and sub params

    - by user210757
    Ok, I understand perl hash slices, and the "x" operator in Perl, but can someone explain the following code example from here (slightly simplified)? sub test{ my %hash; @hash{@_} = (undef) x @_; } Example Call to sub: test('one', 'two', 'three'); This line is what throws me: @hash{@_} = (undef) x @_; It is creating a hash where the keys are the parameters to the sub and initializing to undef, so: %hash: 'one' = undef, 'two' = undef, 'three' = undef The rvalue of the x operator should be a number; how is it that @_ is interpreted as the length of the sub's parameter array? I would expect you'd at least have to do this: @hash{@_} = (undef) x length(@_);

  • Single HTML Table from multiple MySQL tables

    - by David Chouinard
    Hi! I've been struggling for a while with this one; I'll try to explain it here as simply as possible. Consider this MySQL table: +----------+-----------+---------+--------+ |status_id |session_id |pilot_id |present | +----------+-----------+---------+--------+ |1 |61 |901 |1 | |2 |63 |901 |1 | |3 |62 |901 |0 | |4 |62 |902 |1 | |5 |63 |903 |1 | +----------+-----------+---------+--------+ Both session_id and pilot_id are foreign keys making reference to a primary key in another table. The same pilot_id can be associated with different session_id, but every pilot_id-session_id combination is unique. I need to make an HTML table (in PHP) that would display the data like this: +----------+---------+---------+---------+ | |61 |62 |63 | +----------+---------+---------+---------+ |901 |X | |X | |902 | |X | | |903 | | |X | +----------+---------+---------+---------+ Hence, rows are pilot_id and columns are session_id. When a pilot_id-session_id combination has a present value of 1, the corresponding cell should be checked. (ie. when the row-combination is zero or the combination does not exist in the MySQL table, nothing should appear in the HTML table) Phew. Any ideas? Thanks!

  • Which containers / graphics components to use in a simple Java Swing game?

    - by rize
    I'm creating a simple labyrinth game with Java + Swing. The game draws a randomized labyrinth on the screen, places a figure in the middle, and the player is then supposed to find the way out by moving the figure with arrow-keys. As for now, I'm using a plain background and drawing the walls of the labyrinth with Graphics.drawLine(). I have a custom picture of the figure in a .gif file, which I load as a BufferedImage object. However, I want the player to see only part of the labyrinth at a time, and the screen should follow the figure in the game, as the player moves around. I'm planning to do this by creating an Image object of the whole labyrinth when it is created, and then "cutting" a square around the current position of the figure and displaying this with Graphics.drawImage(). I'm new with Swing though, and I can't figure out how to draw the figure at different positions "above" the labyrinth without redrawing the whole thing. Which container/component should I use for the labyrinth and then for the figure to achieve this?

  • sql query question / count

    - by scheibenkleister
    Hi, I have houses that belongs to streets. A user can buy several houses. How do I find out, if the user owns an entire street? street table with columns (id/name) house table with columns (id/street_id [foreign key] owner table with columns (id/house_id/user_id) [join table with foreign keys] So far, I'm using count which returns the result: select count(*), street_id from owner left join house on owner.house_id = house.id group by street_id where user_id = 1 count(*) | street_id 3 | 1 2 | 2 A more general count: select count(*) from house group by street_id returns: count(*) | street_id 3 | 1 3 | 2 How can I find out, that user 1 owns the entire street 1 but not street 2? Thanks.

  • Transactional isolation level needed for safely incrementing ids

    - by Knut Arne Vedaa
    I'm writing a small piece of software that is to insert records into a database used by a commercial application. The unique primary keys (ids) in the relevant table(s) are sequential, but does not seem to be set to "auto increment". Thus, I assume, I will have to find the largest id, increment it and use that value for the record I'm inserting. In pseudo-code for brevity: id = select max(id) from some_table id++ insert into some_table values(id, othervalues...) Now, if another thread started the same transaction before the first one finished its insert, you would get two identical ids and a failure when trying to insert the last one. You could check for that failure and retry, but a simpler solution might be setting an isolation level on the transaction. For this, would I need SERIALIZABLE or a lower level? Additionally, is this, generally, a sound way of solving the problem? Are the any other ways of doing it?

  • Using attr_accessible in a join model with has_many :through relationship

    - by Paulo Oliveira
    I have a USER that creates a COMPANY and become an EMPLOYEE in the process. The employees table has an :user_id and a :company_id. class User has_many :employees has_many :companies, :through => :employees class Employee belongs_to :user belongs_to :company attr_accessible :active class Company has_many :employees has_many :users, :through => employees Pretty basic. But here's the thing, the resource EMPLOYEE has other attributes than its foreign keys, like the boolean :active. I would like to use attr_accessible, but this causes some problems. The attribute :user_id is set right, but :company_id is nil. @user.companies << Company.new(...) Employee id:1 user_id:1 company_id:nil So my question is: if :user_id is set right, despite it is not an attr_accessible, why :company_id isn't set right just the same? It shouldn't be an attr_accessible. I'm using Rails 3.0.8, and have also tested with 3.0.7.

  • PHP and Enums

    - by Henrik Paul
    I know that PHP doesn't have native Enumerations. But I have become accustomed to them from the Java world. I would love to use enums as a way to give predefined values which IDEs' auto completion features could understand. Constants do the trick, but there's the namespace collision problem and (or actually because) they're global. Arrays don't have the namespace problem, but they're too vague, they can be overwritten at runtime and IDEs rarely (never?) know how to autofill their keys. Are there any solutions/workarounds you commonly use? Does anyone recall whether the PHP guys have had any thoughts or decisions around enums?

  • Why is only the suffix of work_index hashed?

    - by Jaroslav Záruba
    I'm reading through the PDF that Brett Slatkin has published for Google I/O 2010: "Data pipelines with Google App Engine": http://tinyurl.com/3523mej In the video (the Fan-in part) Brett says that the work_index has to be a hash, so that 'you distribute the load across the BigTable': http://www.youtube.com/watch?v=zSDC_TU7rtc#t=48m44 ...and this is how work_index is created: work_index = '%s-%d' % (sum_name, knuth_hash(index)) ...which I guess creates something like 'mySum-54657651321987' I do understand the basic idea, but is why only one half of work_index is hashed? Is it important to hash only part of it leaving the suffix out? Would it be wrong to do md5('%s-%d' % (sum_name, index)) so that the hash would be like '6gw8....hq6' ? I'm Java guy so I would use md5 to hash, which means I get id like 'mySum' + 32 characters. (Obviously I want my ids/keys to be as short as possible here.) If I could hash the whole string my id would be just 32 chars. Or would you suggest to use something else to do the hashing with?

  • Is there alternative way to write this query?

    - by Kugel
    I have tables A, B, C, where A represents items which can have zero or more sub-items stored in C. B table only has 2 foreign keys to connect A and C. I have this sql query: select * from A where not exists (select * from B natural join C where B.id = A.id and C.value > 10); Which says: "Give me every item from table A where all sub-items have value less than 10. Is there a way to optimize this? And is there a way to write this not using exists operator?

  • Django how to handle # in variable name.

    - by Jack
    I've got a dictionary in python which is assigned as a template variable. One of the keys is named "#text" but when i try to access it using {{ artist.image.3."#text"}} I get an error which is File "/home/jack/Desktop/test/appengine/lib/django/django/template/__init__.py", line 558, in __init__ raise TemplateSyntaxError, "Could not parse the remainder: %s" % token[upto:] TemplateSyntaxError: Could not parse the remainder: "#text" So how can I use this in the template? I've tried putting quotes around it but to no avail. I'd like to not modify the dictionary if possible, but if its easy enough to do then I guess its okay. Thanks

  • iphone: is there any secure way to establish 2-way SSL from an application

    - by pmilosev
    Hi I need to establish a HTTPS 2-way SSL connection from my iPhone application to the customer's server. However I don't see any secure way to deliver the client side certificates to the application (it's an e-banking app, so security is really an issue). From what I have found so far the only way that the app would be able to access the certificate is to provide it pre-bundeled with the application itself, or expose an URL from which it could be fetched (http://stackoverflow.com/questions/2037172/iphone-app-with-ssl-client-certs). The thing is that neither of this two ways prevent some third party to get the certificate, which if accepted as a risk eliminates the need for 2-way SSL (since anyone can have the client certificate). The whole security protocol should look like this: - HTTPS 2-way SSL to authenticate the application - OTP (token) based user registration (client side key pair generated at this step) - SOAP / WSS XML-Signature (requests signed by the keys generated earlier) Any idea on how to establish the first layer of security (HTTPS) ? regards

  • Python Introspection: How to get varnames of class methods?

  • Implement keyboard control in JavaScript Grid

    - by Vanco
    I finished building a JavaScript grid control, end everything works fine. Paging, button navigation, column sorting, etc. The cells in the grid are DIVs which are generated using Mootools 1.2.4 (which is heavily used throughout the control). I want to implement keyboard control for the grid, both for paging (page up/page down) and for moving with arrow keys inside the rows/cells of the grid. I think that I have to attach an event handler on each cell of the grid and detect what key is being pressed in order to take an appropriate action. But, I can't set the focus on the cells. What am I missing? How do I do this? Any help is appreciated.

  • Is NSDictionary key order guaranteed the same as initialized if it never changes?

    - by Thaurin
    I've run into the same problem as found in this question. However, I have a follow-up question. I seem to be in the same situation as the original asker: I have a plist with a hierarchy of dictionaries that define a configuration screen. These are not mutable and will stay the same throughout the application. Since the original discussion seems to focus on problems arising from mutating the dictionary, I must ask for comfirmation: is the order of a dictionary guaranteed the same as they are in the plist, i.e. as it is read (with initWithContentsOfFile)? Can I use allKeys on it in this case to get a correct-order array of keys if the dictionary never changes?
