  • International Zip Code Search

    - by Dave
    I implemented a U.S. "find near zip code" search for somebody. The coordinates of U.S. zip codes come from a commercial zip code database. Now, they would like a similar ability for countries other than the U.S. Has anybody implemented something like this for non-U.S. searches? How about general "find close to this address" searches? What commercial data is available?

  • doxygen with IDL/ODL

    - by John
    If you have a C++ project that has a bunch of .ODL files and the generated .h files from the ODL compiler, should doxygen be told to parse both .odl and .h, or only one or the other? In general I don't like documenting generated code but IDL is sort of a special case. In any case, it seems like the member listing of ODL files is not quite working properly in my tests, are ODL files properly parsed?

  • Apache with mod_perl eating memory when idle

    - by syneticon-dj
    An Apache webserver running a mod_perl application is exposing abnormal memory usage - after the "day load" ceases, the system's memory is being exhausted by the Apache processes and oom_killer is being invoked. As the load returns the following morning, the memory usage normalizes - probably because Apache workers get recycled periodically if a sufficient number of hits is generated: This is the graph for apache hits per second to correlate: The remaining 2 hits per second throughout the night are induced by HAProxy checks - it runs HEAD http://mydomain.example.com/running HTTP/1.0 requests against the server every half a second with "running" being a static file (i.e. not invoking any perl code). It also seems that disabling these checks remedies the memory usage problem, but obviously cannot be a solution. All of 3 similarly configured servers (behind HAProxy) expose this behavior. The running OS is Ubuntu 10.10, Apache version 2.2.16. This seems to be a memory leak but I have no idea how to start debugging it - any hints?

  • How does pattern matching work behind the scenes in F#?

    - by kryptic
    Hello Everyone, I am completely new to F# (and functional programming in general) but I see pattern matching used everywhere in sample code. I am wondering for example how pattern matching actually works? For example, I imagine it working the same as a for loop in other languages and checking for matches on each item in a collection. This is probably far from correct, how does it actually work behind the scenes?

  • Is it best to code from a blank sheet or improving a code that's already written?

    - by user300371
    Just had a curious thought, but for general coding and programming, do you think it's best to work out all the logic yourself and start from a blank sheet or just take a code that has been written already(by you or someone else) and just change it to your liking? Assuming you have a programming background of like 1year+. (because as a beginner, it's best to learn from nothing) I'm not saying copy+paste someone else's code and say it's yours.

  • hosting website on a private network

    - by razor
    i'm currently running a website off 3 linux servers. I'd like to setup a private network and only allow port 80 traffic to one of the servers. I'd also like to setup a vpn so only I can access the servers via ssh or any port for developing/debugging. How hard is this to setup and what do I need to get? Do enterprise/commercial routers have vpn functionality built in? how do I handle DNS? eg- www.mydomain.com would need to point to the router, which forwards traffic to the webserver. Do I set the A record to the router, and somehow tell the router which server to send the http request to? And how would I make server1.mydomain.com resolve to server1 within the private network (without editing host files)? Would I need to run my own DNS (eg- powerdns?) to do this?

  • No COM1 port on hyper-v

    - by MPX
    I just made a fresh Windows 8.1 install and am trying to set-up a VM for kernel debugging. Therefore, I need to create a serial link to debug the VM using windbg. Usually I just simply add a new COM port and use it as a named pipe. However, I can't find any way to add this hardware. There is nothing relevant on the "add hardware list". What do I need to install this port then? Thanks in advance!

  • Is there a good free (prefrerably PDF) bash tutorial online?

    - by morpheous
    I am finding myself doing a lot more messing around with scripts than I used to and my lack of knowledge in this area (and linux sysadmin/security in general), is becoming a hindrance. Can anyone recommend a good online resource for bash scripting/linux admin. Preferably, it will be in pdf format, so I can copy it (single file) onto my PDA.

  • Object synchronization with GUI Controls in C#

    - by Heka
    Hi, Every time when I change some values in form controls, I need to set a property of an object or vice versa. Instead of writing some methods for each control, I want a general solution for GUI elements. I do not use WPF but only C# 3.0. Any suggestions? Thanks.

  • How can I get Eclipse to insert tabs instead of spaces for Java content assist?

    - by Simon Nickerson
    Is there any way to persuade Eclipse to use tabs instead of spaces for indenting its built-in Java content assist proposals (such as when creating an empty method which overrides a method in the parent class)? The only setting I could find that looked relevant is in Windows/Preferences/General/Editors/Text Editors/Insert spaces for tabs, and this setting is unchecked. At the moment I have to remember to select them and re-format with <Ctrl>+<Shift>+<F>.

  • Your favorite Visual Basic 6 tools and tips

    - by Clay Nichols
    This is somewhat related to a similar post, but that post was Visual Studio 6 in general and a lot of the suggestions didn't apply to VB6. Suggest or vote for tools/tips. Please one tool/tip per post so that everyone can vote on them individually. Include a brief description of what the tools do.

  • Extract dates from filename(C#3.0)

    - by Newbie
    I have a situation where I need to extract dates from the file names whose general pattern is [filename_]YYYYMMDD[.fileExtension] e.g. "xxx_20100326.xls" or x2v_20100326.csv The below program does the work //Number of charecter in the substring is set to 8 //since the length of YYYYMMDD is 8 public static string ExtractDatesFromFileNames(string fileName) { return fileName.Substring(fileName.IndexOf("_") + 1, 8); } Is there any better option of achieving the same? I am basically looking for standard practice. I am using C#3.0 and dotnet framework 3.5 Thanks

  • Delphi: Which are the downsides of having unused units listed in the uses clause?

    - by user193655
    I use cnPack Uses cleaner, but in general which are the downsides of having useless units? I know some of them: 1) of course if the unit is never used across the full project there will be useless resource consuption 2) the code insight will give useless results 3) the code insight will be slower But imagine a simple case: I have a project with 2 forms, I use StrUtils in one of them but I declared StrUtils in both of them... Is there any downside in temrs of memory consumption in this case or not?

  • Referencing dlls built with older .Net versions

    - by stiank81
    In a project using .Net4 - should there be any issues referencing dlls built for older versions of .Net? We're talking 3rd Party dlls here. I'm asking this as a general question. Specifically I have a problem referencing FluentNHibernate.dll - built with .Net3.5. It worked justed fine before I updated my project from .Net3.5 to .Net4.

  • IntelliPoint & Intellitype upgrade to Mouse and Keyboard Center causing system freeze?

    - by Kent England
    I allowed Microsoft to upgrade my wireless keyboard 6000 v3.0 and mouse 6000 v2.0 from Intelliyada v 8.20.468 to what appears to be v9.1.486. This was some time ago, so I can't be certain but this upgrade might be causing my system to freeze on the logon screen (user selection) in Windows 7 Home Premium 32-bit. Mouse and keyboard don't work, but system seems to be running underneath. No indication in Event Viewer about keyboard/mouse driver issues. Might be problem with transceiver hardware. I now have the "Microsoft Mouse and Keyboard Center" UI which isn't very helpful (seems to be very metro) in debugging these drivers. I'm just looking to see if anyone else had problems upgrading to this new Intelliyada software for their MS keyboard and rodent.

  • Why would one server be sending DUP ACK packets to one PC, which is responding with HTTP RST packets?

    - by IronicMuffin
    I'm not a network profressional, so please excuse any wrong language. I was debugging why my DNS traffic was a constant 160Kbps on our corporate network. I opened up a wireshark trace, and I see one PC of a coworker broadcasting HTTP [RST] packets to one of our DMZ servers at the rate of 1000 a second. He restarted his machine, and as soon as it went offline, the server started broadcasting [DUP] [ACK] packets, until he came back online. It then resumed the HTTP [RST] packets. Apparently this server has been doing this kind of behavior since it went live. I believe it did this with a printer and an access point as well. Can anyone explain why this behavior is occurring? Any solutions? The initial research was done because there have been "bandwidth issues" and I wonder if this is contributing.

  • Rails: Serializing objects in a database?

    - by keruilin
    I'm looking for some general guidance on serializing objects in a database. What are serialized objects? What are some best-practice scenarios for serializing objects in a DB? What attributes do you use when creating the column in the DB so you can use a serialized object? How to save a serialized object? And how to access the serialized object and its attributes? (Using hashes?)
