  • Handling User Authentication in .NET?

    - by Daniel
    I am new to .NET, and don't have much experience in programming. What is the standard way of handling user authentication in .NET in the following situation? In Process A, User inputs ID/Password Process A sends the ID/Password to Process B over a nonsecure public channel. Process B authenticates the user with the recieved ID/Password what are some of the standard cryptographic algorithms I can use in above model?

  • Regex: How do I match some regex logic 1 or more times?

    - by tom
    I already have some regex logic which says to look for a div tag with class=something. However, this might occur more than once (one after another). You can't simply add square brackets around that complex regex logic already (e.g. [:some complicated regex logic already existing:]* -- so how do you do it in regex? I want to avoid having to use the programming language logic to append that regex logic after itself if I can... Thanks

  • is Checkland's approach still relevant today?

    - by WeNeedAnswers
    I remember back in the mid 90's that I came across a systems methodology called Checkland's Approach or sometimes called SSM (Soft Systems Methodology). With the advent of Agile and Extreme Programming, not to mention some of the harder methodologies and methods out there related to Object technologies. Is the use of such a methodology still relevant in today's world?

  • How to share information across controllers?

    - by Steffen
    Hi everybody, I recently started programming my first Cocoa app. I have ran into a problem i hope you can help me with. I have a MainController who controls the user browsing his computer and sets some textfield = the chosen folder. I need to retrieve that chosen folder in my AnalyzeController in order to do some work. How do i pass the textfield objectValue from the MainController to the AnalyzeController? Thanks

  • why develop in windows/desktop application?

    - by Alexander
    Just wondering what your comments are regarding the current trend as everything is moving to the web or even the cloud. The significance of an OS or desktop application is getting less attention than web application. So to those folks out there who still develop windows applications, such as WPF. Why still do it? Why not move to web programming? Silverlight instead for example...

  • R in a netbook - system requirements for using R

    - by Brani
    I know it's not a programming question but I'm in a hurry to choose a netbook like this and I haven't been able to find the minimum system requirements for an R installation (e.g. minimum RAM). I am interested in a small netbook so as to be able to use it in class. Has anybody used R in a netbook that would recommend for that use?

  • Programmers joy: the proccess or the result?

    - by faya
    Hello, Recently I stumbled upon this curious question: What is importing for yourself when programming: process or result? I found myself that I love outcome, when everything is done! So I tried to ask some colleagues at work, but all of them responded that they like the development process the most. Myself I like process too, but not as much as outcome. So to which people category you belong too? And if there is a reason, could you express why?

  • Will these optimizations to my Ruby implementation of diff improve performance in a Rails app?

    - by grg-n-sox
    <tl;dr> In source version control diff patch generation, would it be worth it to use the optimizations listed at the very bottom of this writing (see <optimizations>) in my Ruby implementation of diff for making diff patches? </tl;dr> <introduction> I am programming something I have never done before and there might already be tools out there to do the exact thing I am programming but at this point I am having too much fun to care so I am still going to do it from scratch, even if there is a tool for this. So anyways, I am working on a Ruby on Rails app and need a certain feature. Basically I want each entry in a table of mine, let's say for example a table of video games, to have a stored chunk of text that represents a review or something of the sort for that table entry. However, I want this text to be both editable by any registered user and also keep track of different submissions in a version control system. The simplest solution I could think of is just implement a solution that keeps track of the text body and the diff patch history of different versions of the text body as objects in Ruby and then serialize it, preferably in human readable form (so I'll most likely use YAML for this) for editing if needed due to corruption by a software bug or a mistake is made by an admin doing some version editing. So at first I just tried to dive in head first into this feature to find that the problem of generating a diff patch is more difficult that I thought to do efficiently. So I did some research and came across some ideas. Some I have implemented already and some I have not. However, it all pretty much revolves around the longest common subsequence problem, as you would already know if you have already done anything with diff or diff-like features, and optimization the function that solves it. Currently I have it so it truncates the compared versions of the text body from the beginning and end until non-matching lines are found. Then it solves the problem using a comparison matrix, but instead of incrementing the value stored in a cell when it finds a matching line like in most longest common subsequence algorithms I have seen examples of, I increment when I have a non-matching line so as to calculate edit distance instead of longest common subsequence. Although as far as I can tell between the two approaches, they are essentially two sides of the same coin so either could be used to derive an answer. It then back-traces through the comparison matrix and notes when there was an incrementation and in which adjacent cell (West, Northwest, or North) to determine that line's diff entry and assumes all other lines to be unchanged. Normally I would leave it at that, but since this is going into a Rails environment and not just some stand-alone Ruby script, I started getting worried about needing to optimize at least enough so if a spammer that somehow knew how I implemented the version control system and knew my worst case scenario entry still wouldn't be able to hit the server that bad. After some searching and reading of research papers and articles through the internet, I've come across several that seem decent but all seem to have pros and cons and I am having a hard time deciding how well in this situation that the pros and cons balance out. So are the ones listed here worth it? I have listed them with known pros and cons. </introduction> <optimizations> Chop the compared sequences into multiple chucks of subsequences by splitting where lines are unchanged, and then truncating each section of unchanged lines at the beginning and end of each section. Then solve the edit distance of each subsequence. Pro: Changes the time increase as the changed area gets bigger from a quadratic increase to something more similar to a linear increase. Con: Figuring out where to split already seems like you have to solve edit distance except now you don't care how it is changed. Would be fine if this was solvable by a process closer to solving hamming distance but a single insertion would throw this off. Use a cryptographic hash function to both convert all sequence elements into integers and ensure uniqueness. Then solve the edit distance comparing the hash integers instead of the sequence elements themselves. Pro: The operation of comparing two integers is faster than the operation of comparing two strings, so a slight performance gain is received after every comparison, which can be a lot overall. Con: Using a cryptographic hash function takes time to convert all the sequence elements and may end up costing more time to do the conversion that you gain back from the integer comparisons. You could use the built in hash function for a string but that will not guarantee uniqueness. Use lazy evaluation to only calculate the three center-most diagonals of the comparison matrix and then only calculate additional diagonals as needed. And then also use this approach to possibly remove the need on some comparisons to compare all three adjacent cells as desribed here. Pro: Can turn an algorithm that always takes O(n * m) time and make it so only worst case scenario is that time, best case becomes practically linear, and average case is somewhere between the two. Con: It is an algorithm I've only seen implemented in functional programming languages and I am having a difficult time comprehending how to convert this into Ruby based on how it is described at the site linked to above. Make a C module and do the hard work at the native level in C and just make a Ruby wrapper for it so Ruby can make all the calls to it that it needs. Pro: I have to imagine that evaluating something like this in could be a LOT faster. Con: I have no idea how Rails handles apps with ruby code that has C extensions and it hurts the portability of the app. This is an optimization for after the solving of edit distance, but idea is to store additional combined diffs with the ones produced by each version to make a delta-tree data structure with the most recently made diff as the root node of the tree so getting to any version takes worst case time of O(log n) instead of O(n). Pro: Would make going back to an old version a lot faster. Con: It would mean every new commit, the delta-tree would get a new root node that will cost time to reorganize the delta-tree for an operation that will be carried out a lot more often than going back a version, not to mention the unlikelihood it will be an old version. </optimizations> So are these things worth the effort?

  • Getting CoreMIDI to work in snow leopard with SimpleSynth

    - by suman-gurung
    I have been trying to follow the steps in the book Ruby Practical Project - making music with ruby and was trying to get CoreMIDI and output some notes using SimpleSynth. I can connect to the destination but when i do something like midi = LiveMIDI.new midi.note_on(0, 60, 100) I get no output from the sound system. Has anyone tried the code and faced similar situation?? And also What are the better libraries for music programming in Ruby?

  • How to point a subdomain to local server with dynamic IP

    - by jlego
    I see there are many related questions to this one, however the answers given seem to be a little vague for a novice like me. I've got a dedicated LAMP stack running Fedora 16 locally on my home network. Everything works fine internally. I can access the Apache server from other machines on the network using the internal IP in a browser. I'm using the stack for a local file server as well as a development environment for websites. There are a couple of reasons why I would like the development sites hosted on the machine to be available publicly. 1.) I use a CMS that has paid add-ons which allows you to assign the paid license to a domain. I can't develop with paid add-ons on the closed dev server. 2.) I would occasionally like for clients to be able to view the site dev at late stages before it goes live. I have a domain (foo.com, and I want to point a *sub*domain (dev.foo.com) to the local server. I know this is best accomplished with a Static IP, however my IP from my ISP is Dynamic and I don't think there is any way to change that. From what I have read, services like ZoneEdit & DynDNS are supposed to be able to accomplish this, but I have tried both and found it very confusing. Also the server is behind a router and I have also read that you need to set up DDNS(?) in your router, that many routers have presets for these services, and I've found that DynDNS is the only one my router seems to support.

  • Representing server state with a metric

    - by Sal
    I'm using Microsoft's Performance Monitor to dump logs of RAM, CPU, network, and disk usage from multiple servers. I'd like to get a single metric that captures the state of a given variable to a good extent. For instance, disk usage is pretty stable, so if I take a single reading that says I have 50% remaining disk space, that reading will give me an accurate measure for the day. (The servers aren't doing heavy IO writing.) However, the tricky part here is monitoring CPU and network usage. The logs currently dump the % CPU usage every ten seconds. If I take a straight average of the numbers, it may not represent reality, as % CPU will be much lower during the night than day. (We host websites that sell appliance items.) I'd like to get an average over a span during peak hours (about 5 hours in the day) and present a daily peak hour metric. Of course, there are most likely some readings that will come in as overly spiked (if multiple users pinged the server at once) or no use (a momentary idle state). Is there a standard distribution/test industries use in these situation?

  • SATA Windows 7 Problems

    - by Isaacs
    Scenario: Core 2 Duo processor, Gigabyte MB, 4 SATA Western digital 500 GB hard drives, windows 7 64 bit. Problem: Copying data from USB or among SATA hard drives is faulty. When trying to copy 20GB from one HD to another it starts off with normal ~14-15 MB/s transfer rates and eventually bogs down to < 120KB/s transfer rates. If I leave it alone over night I come back with my computer crashed and setting at BIOS detecting hard drives. Troubleshooting: Removed all but 1 HD with OS on it, everything seems to be happy. I can copy large files from USB HD to main/single HD. Ran SpinRite on all hard drives, no errors found. Tried adding one HD to machine and problem exists, tried switching SATA cables, and SATA ports on MB. Reinstalled windows 7 x2 (from different disks..). Oddly enough if I boot to a ubuntu everything works fine. Getting ready to purchase a new MB, but wanted to see if anyone had suggestions. Thanks!
