  • FTP List format

    - by Yvan JANSSENS
    Hi, I'm writing an embedded ftp server, and I cannot get the listing format correctly. The server works completely, only programs like FileZilla cannot interpret the listing format. Here's a sample listing: -rwxr--r-- 1 owner group 640 1970 01 01 test -rwxr--r-- 1 owner group 13440 1970 01 01 test.html -rwxr--r-- 1 owner group 512 1970 01 01 test2.txt Which is basically: permissions[tab]number?[tab]owner[tab]group[tab]filesize[tab]date[tab]filename What am I doing wrong? Thanks, Yvan

  • What are the benefits of learning a new language, as a game developer?

    - by Keand64
    I'm an independant game developer/designer, and I'm wondering what specific benefits are there to learning a new programming language. I do my programming in C++ currently, and I want to know if there are any tangible benefits to learning a different language, as in, benefits to writing a game x in language y versus game w in language z? Basically, I understand that learning a new programming language will help me think about a problem in different ways, but what are some actual benefits to using one language over another in specific scenarios?

  • Concatenate SQL script from Powershell

    - by Jeff Meatball Yang
    I have a bunch of (50+) XML files in a directory that I would like to insert into a SQL server 2008 table. How can I create a SQL script from the command prompt or Powershell that will let me insert the files into a simple table with the following schema: XMLDataFiles ( xmlFileName varchar(255) , content xml ) All I need is for something to generate a script with a bunch of insert statements. Right now, I'm contemplating writing a silly little .NET console app to write the SQL script. Thanks.

  • who wrote 250k unit tests for webkit?

    - by amwinter
    assuming a yield of 3 per hour, that's 83000 hours. 8 hours a day makes 10,500 days, divide by thirty to get 342 mythical man months. I call them mythical because writing 125 tests per person per week is unreal. can any wise soul out there on SO shed some light on what sort of mythical men write unreal quantities of tests for large software projects? thank you.

  • How to make the jump from consumer support to enterprise support?

    - by Zac Cramer
    I am currently a high level consumer break/fix technician responsible for about 300-400 repairs a month. I am good at my job, but bored, and I want to move into the enterprise side of my company, dealing with Server 2008 R2 and exchange and switches and routers that cost more than I make in a month. How do I make this transition? Whats the best thing to learn first? Is there a standard trajectory for making this leap from consumer to business? I am full time employed, so going back to school is not a great option, but I have no life, so spending my nights and weekends reading and practicing is totally within my realm. I am basically overwhelmed by the number of things to learn, and looking for any advice you may have on the best way to proceed. PS - I apologize if this is a not quite the right forum for this, I know its not a technical question exactly, but I also know the sorts of people I want to answer this question are reading this website.

  • Generate 2D cross-section polygon from 3D mesh

    - by nornagon
    I'm writing a game which uses 3D models to draw a scene (top-down orthographic projection), but a 2D physics engine to calculate response to collisions, etc. I have a few 3D assets for which I'd like to be able to automatically generate a hitbox by 'slicing' the 3D mesh with the X-Y plane and creating a polygon from the resultant edges. Google is failing me on this one (and not much helpful material on SO either). Suggestions?

  • linux ftp server with virtual users

    - by kjertil
    i know there are already similar questions for this matter but the answers doesn't really make much sense to anyone who is not really technically comfortable in Linux. I've already tried articles like these for example: http://howto.gumph.org/content/setup-virtual-users-and-directories-in-vsftpd/ with the result of accidently breaking the whole system. The problem is that, while there are several technical possibilities to set up virtual users with a FTP server, it is not as easy as managing for instance a Filezilla server on Windows. I've seen some Web based GUI's but most of them seems to be out of date. The different flavours of Linux and the large amount of different popular FTP servers also seems to make the matter more complicated. I guess my question is, is there a way, to set up virtual FTP users on Linux without the hastle of having to manually edit PAM, MYSQL and config files?

  • Is there a declarative way to force a set of Buttons to be the same size?

    - by Jekke
    I'm writing a form in XAML that has multiple buttons with content of different sizes (ie "OK" and "Save As...") Ideally, I'd like them all to be the smallest size possible to hold the largest content. In the example above, both buttons would be the width necessary to hold "Save As..." plus the margins and padding. If they were Grid cells, I could use a SizeGroup. Is there a similar declaration for Buttons?

  • Commit in SVN without letting other to checkout - is it possible?

    - by strDisplayName
    Hey everybody, I am using SVN as my source control with ANKH and TortoiseSVN. I am writing a huge change in a project, and it takes a few days to make the change, but in the meantime I still want to commit once in a while for backup. But if I commit other team members will get updated with my unfinished work. Is there a way that I can "commit for backup" without changing the revision (so other won't get updated with my changes)? Thanks!

  • iPhone init method return type

    - by William Jockusch
    Suppose we are writing a class (let's call it Class) in an iPhone program. In all the samples out there, the init methods are typically declared like this: -(id) initWithFoo: (Foo *) foo My question is: would it be more logical to do the following? Why or why not? -(Class *) initWithFoo: (Foo *) foo

  • How do I use multiple where clauses in GHCi?

    - by T.R.
    I'm playing around with GHCi for the first time, and I'm having some trouble writing multi-line functions. My code is as follows: Prelude> :{ Prelude| let diffSquares lst = abs $ squareOfSums lst - sumOfSquares lst Prelude| where Prelude| squareOfSums lst = (fst (sumsAndSquares lst))^2 Prelude| sumOfSquares lst = snd (sumsAndSquares lst) Prelude| sumsAndSquares = foldl (\(sms,sqrs) x -> (sms+x,sqrs+x^2)) (0,0) Prelude| :} It gives the following error: <interactive>:1:142: parse error on input `=' Could someone kindly point me in the direction of what I'm missing?

  • Software Architecture: Unit of Work design pattern discussion

    - by santiagobasulto
    Hey everybody. According Martin Fowler's Unit of Work description: "Maintains a list of objects that are affected by a business transaction and coordinates the writing out of changes and resolution of concurrency problems." Avoiding very small calls to the database, which ends up being very slow I'm wondering. If we just delimit it to database transaction management, won't prepare statements help with this?

  • Can you authenticate Facebook Graph entirely from command line with Python?

    - by Sebastian
    I'm writing a (tabbed) application for Facebook that requires a background process to run on a server and, periodically, upload images to an album on this application's page. What I'm trying to do is create a script that will: a) authenticate me with the program b) upload an image to a specific album All of this entirely from the command line and completely with the new Graph API. My problem right now is trying to locate the documentation that will allow me to get a token without a pop-up window of sorts. Thoughts?

  • regular expression for string in c

    - by darkie15
    Hi All, I am working writing a regular expression used to validate string in C. Here is to what I have gone so far '^"[A-Za-z0-9]*[\t\n]*"$' for rules - A string should begin with double quotes - May not contain a newline character However, I am not able to capture the rule for allowing '\' or '"' in a string if preceded with '\'. Here is what I tried: '^"[A-Za-z0-9]*[\t\n]*[\\\|\\"]?"$' But this doesn't seem to work. What might be wrong with the regular expression here? Regards, darkie15

  • How do I accurately handle a batch seperator for SQL from C#

    - by Sam Saffron
    For Data Explorer I would like to add support for a Batch separator. So for example if users type in: select 'GO' go select 1 as go Go select 100 I would like to return the three result sets. Its clear that I need some sort of parser here, my hope is that this is a solved problem and I can just plug it in. (writing a full T-SQL parser is not something I would like to do) What component / demo code could achieve splitting this batch into its 3 parts?

  • ARM Simulator on Windows

    - by Betamoo
    I am studying ARM Processors from a textbook... I thought it will be more useful if I could apply what I learn on an ARM simulator... writing code then watching results and different execution stages would be more fun... I have searched for it, but all I could find was either a freeware on linux or a demo on windows Is there a simulator that allow me to see execution steps and different changes for ARM processor (any version!) that runs on windows?? Thanks

  • How do I negotiate for colo space?

    - by randy melder
    I guess this isn't a technical question, but it definitely is something IT teams deal with, so here goes: I'm looking at getting a rack at a local colocation facility. I'm weighing the options versus building out in a cloud platform. We are REALLY low bandwidth and power. There's a total of six hosts for the total operation. You can assume we use <= 10 amps of power and <= 2Mbps 95th percentile. Do you have any advice for getting the best deal?

  • Why is Perl commonly used as CGI scripts?

    - by Michael Vasquez
    I plan to add a better search feature to my site, so I thought that I would write it in C and use the CGI as a means to access it. But it seems that Perl is the most popular language when it comes to CGI-based stuff. Why is that? Wouldn't it be faster programmed in C or machine code? What advantages, if any, are there to writing it in a scripting language? Thanks.

  • What has changed to make it possible to develop USB3.0

    - by RoboShop
    Like I know the transfer speeds are vastly different. But I don't understand is why they are faster. And why couldn't they have implemented USB 3.0 when they released 1.0? Like what technical breakthrough was required to get transfer speeds that fast? Was it cost? capacities of computer? like they couldn't read the data fast enough? Although USB is still well below hard drive transfer speeds engineering breakthrough? They found some new material which could transfer at a faster rate? Was this in the cable itself? In the hardware?
