• c printing string syntax

  - by user535256

  Hello guys, Just stuck on c syntax regarding strings. Say I have a string like (name[5]="peter";) in c say if I just wanted to print the last character of string or check the last character of the string, which in this case would be 'r' how can I do this? The way I was thinking does not seem to work name[5]="peter"; if(name[5]=="r") printf("last character of name is r"); Question: is there some sort of function to do this that can check one character of array, is a certain value, like name[5] is 'r' in string peter or likewise name[1] is 'n' Also how do I use printf to print that certain char, having problems using printf("last character of name is %s",name[5]) ??? Thanks

• Verify windows log-in via smart card

  - by Ronen Rabinovitz

  Hi I need to verify in my WPF application if the user log in to his computer via password or via smart-card. Both login options are available in my company clients but my application need to open only in the smart-card login. All the clients are windows 7 OS. I look at some sites: http://technet.microsoft.com/en-us/library/ff404285(v=ws.10).aspx http://www.codeproject.com/Articles/240655/Using-a-Smart-Card-Certificate-with-NET-Security-i and I'm thinking I need to get the enhanced key usage (EKU) attribute field. If the EKU is empty = then the user was loged via password and not via smartcard. I only need this simple check, I do not care for creating/validations on certificates atc.

• Strategy for storing and displaying form dropdown data for provinces, states, prefixes?

  - by meder

  I'm currently migrating from a class that stores lists of countries, states & provinces in the form of arrays to using Zend's Locale data in the form of ldml xml files. These ldml files provide localised lists of countries, currencies, languages - so I'm not exactly sure where I should store US States, ( Canadian Provinces ), Prefixes - I was thinking possibly just create a generic xml file and store it in the same directory as the ldml files, but having doubts because it wouldn't really be localised as I'd store it in English. Should I go with storing it in a generic xml file, or possibly update each of the locale files ( eg en.xml ) and append them? The latter is probably not worth the work, which is why I'm swaying towards just a general.xml or dropdown-data.xml. As for generating dropdown options, I suppose I could just say, grab all US states, append the array with Canadian provinces, and append that with an 'Other' option - does this seem like the right way to go about?

• Is there a more efficient way to set variables on a RadioButton's CheckChanged event?

  - by C Patton

  I have 16 radio buttons in an application of mine.. I have to set a variable based on which one was selected.. and I've produced some very ugly code doing this.. private void Foo_CheckedChanged(object sender, EventArgs e) { convertSource = 1; } private void Bar_CheckedChanged(object sender, EventArgs e) { convertSource = 2; } private void Baz_RadioButton_CheckedChanged(object sender, EventArgs e) { convertSource = 3; } Now, I've been thinking about it and to be honest I thought there might have been a way to do it with a switch.. I just can't conceptualize it in my mind. If anyone could show me a more efficient way of doing this, I'd really appreciate it. It's just really bugging me that such a simple thing as this is taking up fifty to seventy lines of code. thanks, cpatton

• No Telnet login prompt when used over SSH tunnel

  - by SCO

  Hi there ! I have a device, let's call it d1, runnning a lightweight Linux. This device is NATed by my internet box/router, hence not reachable from the Internet. That device runs a telnet daemon on it, and only has root as user (no pwd). Its ip address is 192.168.0.126 on the private network. From the private network (let's say 192.168.0.x), I can do: telnet 192.168.0.126 Where 192.168.0.126 is the IP address in the private network. This works correctly. However, to allow administration, I'd need to access that device from outside of that private network. Hence, I created an SSH tunnel like this on d1 : ssh -R 4455:localhost:23 ussh@s1 s1 is a server somewhere in the private network (but this is for testing purposes only, it will endup somewhere in the Internet), running a standard Linux distro and on which I created a user called 'ussh'. s1 IP address is 192.168.0.48. When I 'telnet' with the following, let's say from c1, 192.168.0.19 : telnet -l root s1 4455 I get : Trying 192.168.0.48... Connected to 192.168.0.48. Escape character is '^]'. Connection closed by foreign host . The connection is closed after roughly 30 seconds, and I didn't log. I tried without the -l switch, without any success. I tried to 'telnet' with IP addresses instead of names to avoid reverse DNS issues (although I added to d1 /etc/hosts a line refering to s1 IP/name, just in case), no success. I tried on another port than 4455, no success. I gathered Wireshark logs from s1. I can see : s1 sends SSH data to c1, c1 ACK s1 performs an AAAA DNS request for c1, gets only the Authoritave nameservers. s1 performs an A DNS request, then gets c1's IP address s1 sends a SYN packet to c1, c1 replies with a RST/ACK s1 sends a SYN to c1, C1 RST/ACK (?) After 0.8 seconds, c1 sends a SYN to s1, s1 SYN/ACK and then c1 ACK s1 sends SSH content to d1, d1 sends an ACK back to s1 s1 retries AAAA and A DNS requests After 5 seconds, s1 retries a SYN to c1, once again it is RST/ACKed by c1. This is repeated 3 more times. The last five packets : d1 sends SSH content to s1, s1 sends ACK and FIN/ACK to c1, c1 replies with FIN/ACK, s1 sends ACK to c1. The connection seems to be closed by the telnet daemon after 22 seconds. AFAIK, there is no way to decode the SSH stream, so I'm really stuck here ... Any ideas ? Thank you !

• Cure for puzzle piece programming habits?

  - by Recursion

  Even though I went to a decent CS school, I was still taught with the mentality of programming with puzzle pieces. By puzzle pieces I mean, looking up code segments at each step of the development process and adding them together as needed. Eventually gathering all of the pieces and having a properly working program. So as an example, if in my program the next step is to tokenize a string, I go to google and search "how do I tokenize a string in language". All instead of critically thinking about its implementation. I personally don't think its a very good way to program and I always seem to forget everything that I have searched for. So how can I get out of this puzzle piece mode of programmer that I was taught.

• Safe deployment of ASP.Net applications

  - by gatapia

  Hi All, I have an asp.net app that I want to deploy safely (with as little down time possible). I would love to do something like blue green deployment but without the need for a second web server. So, I know I can use load balancing, etc but I need a quick and cheap approach. I was thinking of doing something like: Setting up another website (copy of original) in IIS, currently I use host headers to direct traffic across sites). I could then view the new site locally until the site is totally online (due to NHibernate start up and various other high intensity tasks this takes a while). Once site 2 is totally started I would then change host headers around giving me a much much smaller down time. So my question is. Has anyone done anything like this? Will IIS restart my app pool or application when changing host headers (making this useless)? Any other options? Thanks for your help all. Guido

• Theory of computation - Using the pumping lemma for context free languages

  - by Tony

  I'm reviewing my notes for my course on theory of computation and I'm having trouble understanding how to complete a certain proof. Here is the question: A = {0^n 1^m 0^n | n>=1, m>=1} Prove that A is not regular. It's pretty obvious that the pumping lemma has to be used for this. So, we have |vy| = 1 |vxy| <= p (p being the pumping length, = 1) uv^ixy^iz exists in A for all i = 0 Trying to think of the correct string to choose seems a bit iffy for this. I was thinking 0^p 1^q 0^p, but I don't know if I can obscurely make a q, and since there is no bound on u, this could make things unruly.. So, how would one go about this?

• Writing temporary data from R

  - by Shane

  I want to write some temporary data to disk in an R package, and I want to be sure that it can run on every OS without assuming the user has admin rights. Is there an existing R function that can provide a path to a temporary directory on all major OS's? Or a way to reference a user's home directory? Otherwise, I was thinking of trying this: Sys.getenv("temp") I presume that I can't expect people to have write access to their R locations, otherwise I could reference a path within the package directory: .find.package("package.name").

• Thoughts/Input about Database Design for a CMS

  - by dallasclark

  I'm just about to expand the functionality of our own CMS but was thinking of restructuring the database to make it simpler to add/edit data types and values. Currently, the CMS is quite flat - the CMS requires a field in the database for every type of stored value (manually created). The first option that comes to mind is simply a table which keeps the data types (ie: Address 1, Suburb, Email Address etc) and another table which holds values for each of these data types. Just like how Wordpress keeps values in the 'options' table, PHP serialize would be used to store an array of values. The second option is how Drupal works, the CMS creates tables for every data type. Unlike Wordpress, this can be a bit of an overkill but really useful for SQL queries when ordering and grouping by a particular value. What's everyone's thoughts?

• Have you been in cases where TDD increased development time?

  - by BillyONeal

  Hello everyone :) I was reading http://stackoverflow.com/questions/2512504/tdd-how-to-start-really-thinking-tdd and I noticed many of the answers indicate that tests + application should take less time than just writing the application. In my experience, this is not true. My problem though is that some 90% of the code I write has a TON of operating system calls. The time spent to actually mock these up takes much longer than just writing the code in the first place. Sometimes 4 or 5 times as long to write the test as to write the actual code. I'm curious if there are other developers in this kind of a scenario.

• What are the pros and cons of using an in memory DB rather than a ThreadLocal

  - by Pangea

  We have been using ThreadLocal so far to carry some data so as to not clutter the API. However below are some of issues of using thread local that which I don't like: 1) Over the years the data items being carried in thread local has increased 2) Since we started using threads (for some light weight processing), we have also migrating these data to the threads in the pool and copying them back again I am thinking of using an in memory DB for these (we doesn't want to add this to the API). I wondering if this approach is good. What are the pros and cons? thx in advance.

• How to properly update a feature branch from trunk?

  - by Pavel Radzivilovsky

  SVN book says: ...Another way of thinking about this pattern is that your weekly sync of trunk to branch is analogous to running svn update in a working copy, while the final merge step is analogous to running svn commit from a working copy I find this approach very unpractical in large developments, for several reasons, mostly related to reintegration step. From SVN v1.5, merging is done rev-by-rev. Cherry-picking the areas to be merged would cause us to resolve the trunk-branch conflicts twice (one when merging trunk revisions to the FB, and once more when merging back). Repository size: trunk changes might be significant for a large code base, and copying the differences files (unlike SVN copy) from trunk elsewhere may be a significant overhead. Instead, we do what we call "re-branching". In this case, when a significant chunk of trunk changes is needed, a new feature branch is opened from current trunk, and the merge is always downward (Feature branches - trunk - stable branches). This does not go along SVN book guidelines and developers see it as extra pain. How do you handle this situation?

• Talking to an Authentication Server

  - by Kyle Terry

  I'm building my startup and I'm thinking ahead for shared use of services. So far I want to allow people who have a user account on one app to be able to use the same user account on another app. This means I will have to build an authentication server. I would like some opinions on how to allow an app to talk to the authentication server. Should I use curl? Should I use Python's http libs? All the code will be in Python. All it's going to do is ask the authentication server if the person is allowed to use that app and the auth server will return a JSON user object. All authorization (roles and resources) will be app independent, so this app will not have to handle that. Sorry if this seems a bit newbish; this is the first time I have separated authentication from the actual application.

• Recover history from foolish git-svn merge

  - by Gregg Lind

  the players: master: the svn branch (actual, not local trackign) mybranch: a local branch My mistake: [master] git svn rebase [master] git merge mybranch [master] git svn dcommit I did this twice. Is there a way I can remedy all this? I was thinking something like: git checkout --hard [commit before the merging] git dcommit # that to the svn? git rebase mybranch git dcommit But this doesn't seem to work. (I know I should a. working from a local tracking branch and b. have rebased rather than merged) I'm in the frantic / willing to send beer to respondents stage :)

• Best practices for using memcached in Rails?

  - by Matt

  Hello everybody, as database transcations in our app are getting more and more time consuming, we have started to use memcached to reduce the amount of queries passed to MySQL. All in all, it works fine and really saves a lot of time. But as caching was "silently appearing" as a workaround to give the app more juice, a lot of our models now contain code like this: def self.all_cached Rails.cache.fetch('object_name') { find( :all, :include => [associations]) } end This is getting more and more a pain as filling and flushing the cache happens in several classes accross the application. Now, I was wondering if there was a better way to abstract memcached logic to make it more powerful and easy to use across all needed models? I was thinking about having some kind of memcached-module which is included in all needed modules. But before playing around, I thought: Let's ask experts first :-) Thanks Matt

• Sorting array containing strings in objective c

  - by jakob

  Hello experts! I have an array named 'names' with strings looking like this: ["name_23_something", "name_25_something", "name_2_something"]; Now I would like to sort this array in ascending order so it looks like this: ["name_25_something", "name_23_something", "name_2_something"]; I guess that should start of with extracting the numbers since I want that the sorting is done by them: for(NSString *name in arr) { NSArray *nameSegments = [name componentsSeparatedByString:@"_"]; NSLog("number: %@", (NSString*)[nameSegments objectAtIndex:1]); } I'm thinking of creating a dictionary with the keys but I'm not sure if that is the correct objective-c way, maybe there some some methods I could use instead? Could you please me with some tips or example code how this sorting should be done in a proper way. Thank you

• LocationMatch and DAV svn

  - by Homes2001

  Hi, I am trying to make our subversion repository accessible via multiple URLs. To do so, I was thinking to use the LocationMatch directive. My configuration is: <Location ~ "/(svn|repository)"> DAV svn SVNPath /opt/svn AuthzSVNAccessFile /etc/subversion/access </Location> The above configuration does NOT work ... Strange thing is that if i use for example this configuration, it works well for both URLs: <Location ~ "/(svn|repository)"> SetHandler server-status </Location> For me it looks like the combination of DAV svn and LocationMatch does not really work... or am I doing something wrong here?

• uniform generation of 3D points on cylinder/cone

  - by Myx

  Hello: I wish to randomly and uniformly generate points on a cylinder and a cone (separately). The cylinder is defined by its center, its radius and height. Same specifications for the cone. I am able to get the bounding box for each shape so I was thinking of generating points within the bounding box. However, I'm not sure how to project them onto the cylinder/cone or if this is the best idea. Any suggestions? Thanks.

• Getting php tips and tutorials as daily emails to improve the knowledge in php programming

  - by Sourabh

  Hi Thanks for your time. This question is related to php programming but not a programming question.I have a young team of php (LAMP + javascript) programmers.I want them to learn better coding and keep themselves updated with the latest advancements in web domain. I was thinking if there was any web site which send daily emails about php questions / problems/ solutions to common problems/ tips which will practically help the people to spend 10-15 minutes daily and enjoy the learning.This will also kind of automate the habit of self learning on daily basis. There are lots of PHP forums and php tutorials website, I tried to google but I did not find any website which does what I am looking for. Please let me know if you know such website.If you have any other ideas to achieve the goal are also welcome. -Sourabh

• in-memory database in Python

  - by Claudiu

  I'm doing some queries in Python on a large database to get some stats out of the database. I want these stats to be in-memory so other programs can use them without going to a database. I was thinking of how to structure them, and after trying to set up some complicated nested dictionaries, I realized that a good representation would be an SQL table. I don't want to store the data back into the persistent database, though. Are there any in-memory implementations of an SQL database that supports querying the data with SQL syntax?

• dilemma about mysql. using condition to limit load on a dbf

  - by ondrobaco

  hi, I have a table of about 800 000 records. Its basically a log which I query often. I gave condition to query only queries that were entered last month in attempt to reduce the load on a database. My thinking is a) if the database goes only through the first month and then returns entries, its good. b) if the database goes through the whole database + checking the condition against every single record, it's actually worse than no condition. What is your opinion? How would you go about reducing load on a dbf?

• shared libraries creating a soft link

  - by robUK

  Hello, Redhat 5.5 gcc version 4.1.2 I have a directory call lib, and in that directory I have all the shared libraries (about 30) that we get from our customer as we use their API. We link with this API. directory structure: /usr/CSAPI/lib However, our customer will update their API so we get new libraries, normally about 3 or 4. What I have been doing is when I get new libraries. Is to remove the old one and put in another directory. And replace them with the new libaries in the lib directory. /usr/CSAPI/Old_libs The new and old will have the same name. i.e. libcs.so < old libcs.so < new Is there a better way to manage this? I was thinking of creating a soft line, but as the names are the same, I am not sure that this will work. Many thanks,

• What is a typical scenario for and end-user reports design?

  - by Sebastian

  Hello! I'm wondering what would be the typical scenario for using an end-user report designer. What I'm thinking of is to have a base report with all the columns that I can have, also with a basic view of the report (formatting, order of columns, etc.) and then let the user to change that format and order, take out or add (from the available columns) data to it, etc. Is that a common way to address what is called end-user designer for reports or I'm off track? I know it depends on the user (if it's someone that can handle SQL or not for example), but is it common to have a scenario where the user can build everthing from the sql query to the formatting? Thanks! Sebastian
