  • SSIS Null Value Questions

    - by Saobi
    I have a table with 5 string columns, all can be NULLs. After I read the data from this table, I want to convert any null values into empty strings. The reason is that I need to compare these columns with columns in another table of the same schema (using conditional split), and null values would cause the comparison to evaluate to NULL. Is there any functionality in SSIS that allows me to convert NULL's to empty strings, or just not having to deal with NULL's at all?

  • void foo(int &x) -> Ruby? Passing integers by reference?

    - by Earlz
    Hello, as a way to spice up my C++ programming homework, I've decided to instead of typing the C++ from the book onto my computer, instead reforming it in Ruby. Yes it's a bit silly, but I'm bored. Anyway, I'm having trouble converting this kind of function to Ruby void swap(int &a,int &b){ int c=b; b=a; a=c } What would the equivalent ruby code looking inside a function ?

  • Python: Comparing specific columns in two csv files

    - by coder999
    Say that I have two CSV files (file1 and file2) with contents as shown below: file1: fred,43,Male,"23,45",blue,"1, bedrock avenue" file2: fred,39,Male,"23,45",blue,"1, bedrock avenue" I would like to compare these two CSV records to see if columns 0,2,3,4, and 5 are the same. I don't care about column 1. What's the most pythonic way of doing this? EDIT: Some example code would be appreciated.

  • Java compilation with two versions of Eclipse

    - by lepnio
    I've got an old project in Eclipse 2.1 and compiled with a JDK 1.4.2_12. I want to upgrade the version of Eclipse to Eclipse Galileo. I've imported my project and set the compilation level to 1.4 and I've also updated my build path to use the correct JDK. The problem is that when I compare the compiled files in the classes folder in the two versions of Eclipse, the MD5 checksum are different. Should I be worried about that fact or this is normal?

  • Unique DVD info?

    - by acidzombie24
    I was wondering, is there some type of disc ID i can use to search in my database to see if that disc is has been scanned or not? All disc were created by me typically burnt on windows. -edit- I could compare write time and volume label to see if the disc has been scanned but i notice if i put in certain commercial disc that fields are blank or wrong causing many false positives (i once had the time set to the future, i dont know if people want to archive the contents of files on a commercial disc in my app).

  • Updating an atom with a single value

    - by mikera
    I have a number of atoms in my code where a common requirement is to update them to a new value, regardless of the current value. I therefore find myself writing something like this: (swap! atom-name (fn [_] (identity new-value))) This works but seems pretty ugly and presumably incurs a performance penalty for constructing the anonymous closure. Is there a better way?

  • making a password-only auth with bcrypt and mongoose

    - by user3081123
    I want to create service that let you login only with password. You type a password and if this password exists - you are logged in and if it's not - username is generated and password is encrypted. I'm having some misunderstandings and hope someone would help me to show where I'm mistaken. I guess, it would look somewhat like this in agularjs First we receive a password in login controller. $scope.signup = function() { var user = { password: $scope.password, }; $http.post('/auth/signup', user); }; Send it via http.post and get in in our node server file. We are provided with a compare password bcrypt function userSchema.methods.comparePassword = function(candidatePassword, cb) { bcrypt.compare(candidatePassword, this.password, function(err, isMatch) { if (err) return cb(err); cb(null, isMatch); }); }; So right now we are creating function to catch our http request app.post('/auth/signup', function(req, res, next) { Inside we use a compair password function to realize if such password exists or not yet. So we have to encrypt a password with bcrypt to make a comparison First we hash it same way as in .pre var encPass; bcrypt.genSalt(10, function(err, salt) { if (err) return next(err); bcrypt.hash(req.body.password, salt, function(err, hash) { if (err) return next(err); encPass=hash; )}; )}; We have encrypted password stored in encPass so now we follow to finding a user in database with this password User.findOne({ password: encPass }, function(err, user) { if (user) { //user exists, it means we should pass an ID of this user to a controller to display it in a view. I don't know how. res.send({user.name}) //like this? How should controller receive this? With $http.post? } else { and now if user doesn't exist - we should create it with user ID generated by my function var nUser = new User({ name: generId(), password: req.body.password }); nUser.save(function(err) { if (err) return next(err); )}; )}; )}; Am I doing anything right? I'm pretty new to js and angular. If so - how do I throw a username back at controller? If someone is interested - this service exists for 100+ symbol passphrases so possibility of entering same passphrase as someone else is miserable. And yeah, If someone logged in under 123 password - the other guy will log in as same user if he entered 123 password, but hey, you are warned to make a big passphrase. So I'm confident about the idea and I only need a help with understanding and realization.

  • What does this `_time_independent_equals` mean?

    - by Satoru.Logic
    In the tornado.web module there is a function called _time_independent_equals: def _time_independent_equals(a, b): if len(a) != len(b): return False result = 0 for x, y in zip(a, b): result |= ord(x) ^ ord(y) return result == 0 It is used to compare secure cookie signatures, and thus the name. But regarding the implementation of this function, is it just a complex way to say a==b?

    - by astropanic
    What are correctly content-types for this documents ? I need to write a simple crawler, that only fetches this kind of files. Nowadays http://somedomain.com/index.html can serve for example an JPEG file due to mod_rewrite, so I need to check the content-type from the response header and compare it with a list of allowed content-types. From where I can get such list ?

  • Merging list problem

    - by Martin Malmstrøm
    Sorry about the bad heading, but the question was not easy to compress into one sentence... I have two lists of contigs (list1 and list2). They contain mostly unique contigs, but with some overlap. I want to compare list1 and list2 and then create a list3 that contains all contigs in list1 minus those also present in list2. Is this possible with a simple cat/paste/grep/sort/uniq kind of batch command? Thanks!
