  • Client asked for internet radio on his website

    - by Ali
    Hi guys, I have a freelance job for a php site. The client isn't a tech savy guy he says he would like to have internet radio on his website as well. Now the thing is that when we speak of internet radio what are we actually talking about? My client himself has no idea of what internet radio is aside form listening to streaming mp3s on a flash player embedded on a website. I don't think my client would be ready to set up a radio station or so.. I have to give my client a report on what can and cannot be done. So I'm looking for the simplest solution possible that would pass off as internet radio...

  • LINQ 4 XML - What is the proper way to query deep in the tree structure?

    - by Keith Barrows
    I have an XML structure that is 4 deep: <?xml version="1.0" encoding="utf-8"?> <EmailRuleList xmlns:xsd="EmailRules.xsd"> <TargetPST name="Tech Communities"> <Parse emailAsList="true" useJustDomain="false" fromAddress="false" toAddress="true"> <EmailRule address="@aspadvice.com" folder="Lists, ASP" saveAttachments="false" /> <EmailRule address="@sqladvice.com" folder="Lists, SQL" saveAttachments="false" /> <EmailRule address="@xmladvice.com" folder="Lists, XML" saveAttachments="false" /> </Parse> <Parse emailAsList="false" useJustDomain="false" fromAddress="false" toAddress="true"> <EmailRule address="[email protected]" folder="Special Interest Groups|Northern Colorado Architects Group" saveAttachments="false" /> <EmailRule address="[email protected]" folder="Support|SpamBayes" saveAttachments="false" /> </Parse> <Parse emailAsList="false" useJustDomain="false" fromAddress="true" toAddress="false"> <EmailRule address="[email protected]" folder="Support|GoDaddy" saveAttachments="false" /> <EmailRule address="[email protected]" folder="Support|No-IP.com" saveAttachments="false" /> <EmailRule address="[email protected]" folder="Discussions|Orchard Project" saveAttachments="false" /> </Parse> <Parse emailAsList="false" useJustDomain="true" fromAddress="true" toAddress="false"> <EmailRule address="@agilejournal.com" folder="Newsletters|Agile Journal" saveAttachments="false"/> <EmailRule address="@axosoft.ccsend.com" folder="Newsletters|Axosoft Newsletter" saveAttachments="false"/> <EmailRule address="@axosoft.com" folder="Newsletters|Axosoft Newsletter" saveAttachments="false"/> <EmailRule address="@cmcrossroads.com" folder="Newsletters|CM Crossroads" saveAttachments="false" /> <EmailRule address="@urbancode.com" folder="Newsletters|Urbancode" saveAttachments="false" /> <EmailRule address="@urbancode.ccsend.com" folder="Newsletters|Urbancode" saveAttachments="false" /> <EmailRule address="@Infragistics.com" folder="Newsletters|Infragistics" saveAttachments="false" /> <EmailRule address="@zdnet.online.com" folder="Newsletters|ZDNet Tech Update Today" saveAttachments="false" /> <EmailRule address="@sqlservercentral.com" folder="Newsletters|SQLServerCentral.com" saveAttachments="false" /> <EmailRule address="@simple-talk.com" folder="Newsletters|Simple-Talk Newsletter" saveAttachments="false" /> </Parse> </TargetPST> <TargetPST name="[Sharpen the Saw]"> <Parse emailAsList="false" useJustDomain="false" fromAddress="false" toAddress="true"> <EmailRule address="[email protected]" folder="Head Geek|Job Alerts" saveAttachments="false" /> <EmailRule address="[email protected]" folder="Social|LinkedIn USMC" saveAttachments="false"/> </Parse> <Parse emailAsList="false" useJustDomain="false" fromAddress="true" toAddress="false"> <EmailRule address="[email protected]" folder="Head Geek|Job Alerts" saveAttachments="false" /> <EmailRule address="[email protected]" folder="Head Geek|Job Alerts" saveAttachments="false" /> <EmailRule address="[email protected]" folder="Social|Cruise Critic" saveAttachments="false"/> </Parse> <Parse emailAsList="false" useJustDomain="true" fromAddress="true" toAddress="false"> <EmailRule address="@moody.edu" folder="Social|5 Love Languages" saveAttachments="false" /> <EmailRule address="@postmaster.twitter.com" folder="Social|Twitter" saveAttachments="false"/> <EmailRule address="@diabetes.org" folder="Physical|American Diabetes Association" saveAttachments="false"/> <EmailRule address="@membership.webshots.com" folder="Social|Webshots" saveAttachments="false"/> </Parse> </TargetPST> </EmailRuleList> Now, I have both an FromAddress and a ToAddress that is parsed from an incoming email. I would like to do a LINQ query against a class set that was deserialized from this XML. For instance: ToAddress = [email protected] FromAddress = [email protected] Query: Get EmailRule.Include(Parse).Include(TargetPST) where address == ToAddress AND Parse.ToAddress==true AND Parse.useJustDomain==false Get EmailRule.Include(Parse).Include(TargetPST) where address == [ToAddress Domain Only] AND Parse.ToAddress==true AND Parse.useJustDomain==true Get EmailRule.Include(Parse).Include(TargetPST) where address == FromAddress AND Parse.FromAddress==true AND Parse.useJustDomain==false Get EmailRule.Include(Parse).Include(TargetPST) where address == [FromAddress Domain Only] AND Parse.FromAddress==true AND Parse.useJustDomain==true I am having a hard time figuring this LINQ query out. I can, of course, loop on all the bits in the XML like so (includes deserialization into objects): XmlSerializer s = new XmlSerializer(typeof(EmailRuleList)); TextReader r = new StreamReader(path); _emailRuleList = (EmailRuleList)s.Deserialize(r); TargetPST[] PSTList = _emailRuleList.Items; foreach (TargetPST targetPST in PSTList) { olRoot = GetRootFolder(targetPST.name); if (olRoot != null) { Parse[] ParseList = targetPST.Items; foreach (Parse parseRules in ParseList) { EmailRule[] EmailRuleList = parseRules.Items; foreach (EmailRule targetFolders in EmailRuleList) { } } } } However, this means going through all these loops for each and every address. It makes more sense to me to query against the Objects. Any tips appreciated!

  • SSAS 2008 backup/restore fails with a GetOverlappedResult 'Insufficient system resources exist to co

    - by Anant Aneja
    Hi, On my SSAS 2008 instance if a backup/restore of any database is made to/from a UNC path I get an error : The following system error occurred from a call to GetOverlappedResult for Physical file: '\server\share\OLAPDB.abf', Logical file: '' : Insufficient system resources exist to complete the requested service. . Server: The operation has been cancelled. (Microsoft.AnalysisServices) Creating/copying/moving a file on the share of any size on the share using explorer or the command prompt works. The most useful link I could find is : http://www.tech-archive.net/Archive/Development/microsoft.public.win32.programmer.kernel/2004-07/0475.html Can anyone shed more light on what could be causing this error ? (I've posted the same question on the SSAS forums - just a heads up)

  • How do I sign exes and dlls with my code signing certificate

    - by Tim
    (I purchased a code signing cert from Thawte and have been going out of my mind with frustration at the whole process. What I have from them are: .spc / .p7b file .pvk file (NOTE I do not have a pfx file from them. God knows why, but I have been fighting with their tech support for a week) In any case I find "help" links on their site and at MS for signcode.exe which is useless for me because I can't find that exe on my machine, however I do have signtool.exe. Unfortunately i am mystified at the command line parameters listed on this MS help site. Specifically, what parameters do I use and what values? I tried what I thought was obvious but it does not work at all. I can get the signing wizard to work, however I need this to work non-interactively in a hudson CI batch file. It really doesn't seem like it should be this difficult, but so far it is all black magic. thanks for any help

And I only wish to get info about this single attribute "Employeers-ID". Can anyone help me with this? Thanks in advance!

  • "Cannot perform a differential backup for database "myDb", because a current database backup does no

    - by krimerd
    Hi there, I have what seems to be a pretty common problem when trying to take a differential backup. We have a SQL Server 2008 Standard (64bit) and we use Litespeed v 5.0.2.0 to take our backups. We take full backups once a week and a differential on a daily basis. The problem is, every time I try to take a diff backup I get the following error: "VDI open failed due to requested abort. BACKUP DATABASE is terminating abnormally. Cannot perform a differential backup for database "myDb", because a current database backup does not exist. Perform a full database backup by reissuing BACKUP DATABASE, omitting the WITH DIFFERENTIAL option." The problem is that I know 100% I have a full backup because I just double checked. Only once I was able to take a diff backup and that was when I took it immediately after I took a full backup. I have searched around and noticed that this is pretty common (although mostly with SQL 2005) and a solution that a lot of ppl suggest and that I haven't tried yet is to disable the SQL Server VSS Writer service. The problem with this is #1 I think I might need this service since I am using a third party backup software and #2 I am not sure exactly what the service does and don't want to disable it just like that. Has any of you ever experienced this problem and how did you go about fixing it? Thank you,

  • Postgres cannot connect to server

    - by user1408935
    Super stumped by why Postgres isn't working on a new app I just started. I've got it working for one app already. I'm using postgres.app, and it's running. I started a new app with rails new depot -d postgresql and then I went into the database.yml file and changed username to my $USER (which is what it is for the other app, which is working). So now my database.yml file has this development section: development: adapter: postgresql encoding: unicode database: depot_development pool: 5 username: <username> password: But when I run "rake db:create" or "rake db:create:all" I still got this error (in full, cause I don't know what's relevant): Couldn't create database for {"adapter"=>"postgresql", "encoding"=>"unicode", "database"=>"depot_development", "pool"=>5, "username"=>"<username>", "password"=>nil} could not connect to server: Permission denied Is the server running locally and accepting connections on Unix

  • VMware vSphere Hypervisor 5 with Intel SPL 5000 in Raid 0 no boot from DVD?

    - by Richard
    I hope this is the correct StackExchange, since I am only using StackOverflow for Web development, but need some help with my server configuration. I would like to install VMware vSphere Hypervisor 5 on my server here at home and run a view machines on it such as Windows Server 2008 and Red Hat. I used to have either OpenSuse or Windows Server 2008 installed but I would like to get into VMWare Hypervisor. My hardware configuration: - Intel S5000PSL with bios version S5000.86B.10.60.0091 build date 10/09/2008 as of read out of bios - E5420 @ 2.5GHz Intel Xeon CPU The Intel Virtualization Technology is enabled in the BIOS - DVD DH20A4P DVD Writer - 8GB ECC Ram I have configured a RAID 0 on my 2 WD 2TB SATA drives I have burned the Hypervisor 5 on an empty DVD and it is bootable, I tested it on my client PC. The main problem here is basically, that I cannot boot the DVD on my server. I have set the Boot Option to the DVD drive. I have booted from the BIOS straight in the DVD drive and it does not work. I do not see any error messages. The only thing I see are the PXE error messages when it tries booting from the network and other devices, obviously without any result. Does anybody know why I cannot boot the DVD? What could cause the problem? I have sucessfully installed Windows Server 2008 via original DVD about 1 year ago, so the DVD drive can read and does work. The DVD drive is available in the BIOS and I have checked all cables and none of them is loose in any way. I even see the light flashing but it does not want to boot from the DVD. I am looking forward to suggestions and things that I should check. Thank you very much

  • How to start develop for chinese mobile phones based on nucleus RTOS? (MTK)

    - by juckobee
    I've noticed that chinese mobile phones became very popular, perhaps because of their very reasonable price and many modern features (touch screens, advanced multimedia, double sim cards etc). I'm wondering if there's any way to develop custom solutions for this handsets as independent developer? How to obtain a toolkit and documentation? I've found some resources, but mainly inconsistent tech notes, often in chinese only. For now I know, that majority of chinese handsets are based on chips from MediaTek (MTK), with operating system based on Nucleus RTOS and MMI (plutoMMI?) framework. Unfortunately, there is no Java RE avaiable (ok, there are some handsets with Java, however, Java isn't something I'm looking for) Is there any SDK, documentation, emulators/simulators, how-tos, etc avaiable? How to develop, deploy and test custom application for MTK mobile?

  • Solving embarassingly parallel problems using Python multiprocessing

    - by gotgenes
    How does one use multiprocessing to tackle embarrassingly parallel problems? Embarassingly parallel problems typically consist of three basic parts: Read input data (from a file, database, tcp connection, etc.). Run calculations on the input data, where each calculation is independent of any other calculation. Write results of calculations (to a file, database, tcp connection, etc.). We can parallelize the program in two dimensions: Part 2 can run on multiple cores, since each calculation is independent; order of processing doesn't matter. Each part can run independently. Part 1 can place data on an input queue, part 2 can pull data off the input queue and put results onto an output queue, and part 3 can pull results off the output queue and write them out. This seems a most basic pattern in concurrent programming, but I am still lost in trying to solve it, so let's write a canonical example to illustrate how this is done using multiprocessing. Here is the example problem: Given a CSV file with rows of integers as input, compute their sums. Separate the problem into three parts, which can all run in parallel: Process the input file into raw data (lists/iterables of integers) Calculate the sums of the data, in parallel Output the sums Below is traditional, single-process bound Python program which solves these three tasks: #!/usr/bin/env python # -*- coding: UTF-8 -*- # basicsums.py """A program that reads integer values from a CSV file and writes out their sums to another CSV file. """ import csv import optparse import sys def make_cli_parser(): """Make the command line interface parser.""" usage = "\n\n".join(["python %prog INPUT_CSV OUTPUT_CSV", __doc__, """ ARGUMENTS: INPUT_CSV: an input CSV file with rows of numbers OUTPUT_CSV: an output file that will contain the sums\ """]) cli_parser = optparse.OptionParser(usage) return cli_parser def parse_input_csv(csvfile): """Parses the input CSV and yields tuples with the index of the row as the first element, and the integers of the row as the second element. The index is zero-index based. :Parameters: - `csvfile`: a `csv.reader` instance """ for i, row in enumerate(csvfile): row = [int(entry) for entry in row] yield i, row def sum_rows(rows): """Yields a tuple with the index of each input list of integers as the first element, and the sum of the list of integers as the second element. The index is zero-index based. :Parameters: - `rows`: an iterable of tuples, with the index of the original row as the first element, and a list of integers as the second element """ for i, row in rows: yield i, sum(row) def write_results(csvfile, results): """Writes a series of results to an outfile, where the first column is the index of the original row of data, and the second column is the result of the calculation.

I would appreciate any insight here as to how you concurrency gurus would approach this problem. Here are some questions I had when thinking about this problem. Bonus points for addressing any/all: Should I have child processes for reading in the data and placing it into the queue, or can the main process do this without blocking until all input is read? Likewise, should I have a child process for writing the results out from the processed queue, or can the main process do this without having to wait for all the results? Should I use a processes pool for the sum operations? If yes, what method do I call on the pool to get it to start processing the results coming into the input queue, without blocking the input and output processes, too? apply_async()? map_async()? imap()? imap_unordered()? Suppose we didn't need to siphon off the input and output queues as data entered them, but could wait until all input was parsed and all results were calculated (e.g., because we know all the input and output will fit in system memory). Should we change the algorithm in any way (e.g., not run any processes concurrently with I/O)?

  • Dynatree multi - selection implementaion ala Windows style

    - by gnomixa
    I would like to implement windows style multi-selection: when user holds CTRL key and selects several nodes of the tree. Dynatree (from here http://wwwendt.de/tech/dynatree/doc/dynatree-doc.html) by default has checkboxes for node selection which my client doesn't seem to like. My question is, is it possible to implement what I need using provided set of callbacks? also, curently, when I hold CTRL key and click on the node, it opens a new window. Is there any way to suppress this functionality? i am guess I would have to do through CSS?

  • ruby xmpfilter on windows

    - by dreftymac
    Has anyone out there ever gotten xmpfilter to work on windows? xmpfilter "unterminated string meets end of file" is the error. The only Google hit is in Japanese: google://xmpfilter "unterminated string meets end of file" http://www.unkar.org/read/pc12.2ch.net/tech/1249687283 For background, the desired feature from xmpfilter is to get automatic "eval" annotations of Ruby sourcecode: Before: a = "bravo alpha charlie" # => b = a.split # => b.sort! # => After: a = "bravo alpha charlie" # => "bravo alpha charlie" b = a.split # => ["bravo", "alpha", "charlie"] b.sort! # => ["alpha", "bravo", "charlie"]

  • How do I make the "change order" button appear in SharePoint 2010?

    - by Jan Aagaard
    How do I make the "change order" button appear in SharePoint 2010? I have followed a guide that allowed me to add OrderedList="TRUE" to my list template. This makes it possible to select "Allow users to order items in this view" for my view. But the change order button is still missing. Any idears on what I am missing? I am using SharePoint 2010 and the guide is from 2006, so that might explain why it doesn't just work. The guide from tech-archive.net.

  • Live Mesh starts exactly once on fresh Win7 Ultimate installation

    - by Reb.Cabin
    I did a fresh install of Windows 7 Ulimate 64-bit on a formatted drive on a refurbed Lenovo PC, applied all 102 (!) windows updates, windows seems to be working fine. No quirks installing, no apps, no junkware, just straight, legal, Win7 Ultimate right from an unopened 2009 Microsoft box. Ok, breathe sigh -- Install Live Mesh (no messenger, no mail, no writer, no photo, none of the rest of the Windows Live freeware). Set up my shares, let it run overnight. watch MOE.exe in the Task-Manager perf pane to make sure it's all settled down. reboot. Ok, check that MOE is running and files are getting updated properly from other machines in the mesh. Great. HOWEVER -- when I try to launch Windows Live Mesh app from the Start jewel, I get a brief hourglass, then nothing. Reboot. Same story. result -- the shares I already posted seem to be synching properly, but I can't run the app, so I can't add and delete shares. The background process MOE seems to run, but I can't get the app going. btw, the reason I did this fresh install is I had exactly the same experience running Vista, so I wiped the machine hoping it would solve this nasty problem. Imagine my surprise! Will be grateful for clues, advice, etc, please & thanks!

  • IBM Thinkpad 240 - Best way to boot from floppy to USB - Best Linux for 300 MHz 128 MB RAM 800x600 s

    - by zillion
    Mostly I still have that old 'ultraportable' laptop that is mostly like a pre-netbook era laptop and a friend and programmer needs a computer because the one he was using just broke and he has to wait until the new one arrive in 4-6 weeks ... This laptop has no LAN connection and CD-ROM so be prepared for a real challenge! All hardware is well supported on Windows XP (included drivers on the Windows XP CD) and on Linux out-of-the-box (but the screen need a special configuration.) Mostly any Linux that will work well with Skype (USB or regular headset), any MSN client and a text writer for code will do. What I have tested so far: Slitaz 2 don't boot because the floppy of GRUB4DOS don't see the USB drive (fully working and tested on my regular laptop), Damn Small Linux was working but was needing a special screen configuration that I don't remember (in the boot options of the floppy) and now I'm thinking about Puppy Linux that is seen to work totally out of the box with it but I will need an old Puppy version (1 or 2 I think) and the Wakepup floppy ... If you got some ideas to help or to try I'm open!

  • Disable write-protection on Micro SD

    - by Tim
    My task today is to open up and copy some files to 700 brand new micro SD cards. As I get going on this task I am finding that some of the Micro SD cards are telling me "sorry this drive is write protected" To copy the files I am using a standard SD to micro SD card adapter, and a USB SD card reader / writer. I have ensured that the switch is set to OFF on all of my adapters. As soon as I get a Micro SD that tells me it is write protected I can use the same adapter with another micro SD and it works fine, so I know the problem is not with my adapters. My question is: How can I disable the write protection on a Micro SD card? This eHow article seems to indicate that there is also a physical switch on Micro SD cards. However I have personally never seen a Micro SD with a physical switch, and none of the ones I am using today have said switch. Since these cards are brand new and thus empty are the ones that are telling me they are write protected simply useless? Could this be caused by some sort of defect in the cards?

  • WAN Optimization Resources

    - by Paul
    I'm looking for resources on writing software to do WAN optimization. I've googled this and searched SO, but there doesn't seem to be much around. The only things I've found are high-level articles in tech magazines, and info for network admins on how to make use of existing WAN optimization products. I'm looking for something on the techniques etc. used to write WAN optimization software. It seems to be a dark art, and the people who know how to do it, guard their secrets closely. Any suggestions?

  • Execution of "mvn sonar:sonar" with no external access

    - by romaintaz
    Hello, I try to execute the mvn sonar:sonar command on a machine where Maven is configured to have no access to external repositories (in reality, this is not exactly the case, but it helps me to explain my problem). So currently, if I run this command, I get the following error: [ERROR] BUILD ERROR [INFO] ------------------------------------------------------------------------ [INFO] The plugin 'org.codehaus.mojo:sonar-maven-plugin' does not exist or no valid version could be found I think it means that I have some incorrect metadata in my local repository, as I have a [local repo]\org\codehaus\mojo\sonar-maven-plugin\1.0-beta-1 directory (with the JAR inside, of course). Have you any idea why my command is failing? tech infos: Maven 2.2.1, Java 1.6, Sonar 2.1.2

  • McAfee Virus Scan and Oracle RAC

    - by Lee Gathercole
    Hi, We're experiencing a strange problem with Oracle RAC and McAfee anti-virus. As part of the installation of the Oracle RAC we disable anti virus as directed. We have had our RAC running fine, but when we came to re-enable the AV and reboot we got the BSOD. Abnormal Program Termination (BugCheck, STOP: 0x00000035 (0x8E984678, 0x00000000, 0x00000000, 0x00000000 NO_MORE_IRP_STACK_LOCATIONS Following the standard process of raising this problem with Microsoft they identify the problem and also a fix. Microsoft talk about too many file filter drivers being present and pushing the DFS upper limit beyond the default size. Upping this value, as per msdn, has no impact. We're able to recover from this BSOD by disabling AV. We don't have the problem if we run the AV service manually whilst the system is up. However, if we make the service automatic we fail to boot.

  • No OS will boot, all freeze

    - by Gyan
    This is for a computer with the following configuration: Asus P5KPL-AM/PS motherboard Pentium D 820 (dual core 2.8 GHz) 1 x 2 GB DDR2-800 Transcend RAM 1 SATA2 Samsung 160 GB HDD 1 PATA LG CD/DVD Writer PS/2 generic Keyboard USB Razer mouse The computer was working fine till a month ago with a Hitachi HDD in place of the Samsung. But that drive died and I sent it in for warranty replacement. Since then and till last week, the computer had not been turned on. I then got hold of a spare but XPSP2-loaded Samsung drive from another computer and decided to get this computer temporarily running. However, when I tried to boot into XP, it didn't load. It got stuck at the first graphical screen. When trying Safe Mode, the file list would be updated up to diskio.sys and then freeze. If I tried to boot Kubuntu off a CD, I would get past the first menu, but then get stuck at the subsequent graphical interface in the loading process. A similar thing happend with a friend's Windows XP-on-a-pen-drive. I switched the RAM into the other slot, but no luck. Then I booted the Ultimate Boot CD and ran Memtest86+ and a couple of the bundled CPU stress tests but these detected no errors. Some searching on the Internet brought up the notion of the CPU failing to switch from "real" to "protected mode". I'm hoping to get a fix on what the problem is and what I can do about it. Edit: I've flashed to the latest BIOS, but that doesn't help. Also, Knoppix LiveCD also freezes. I notice that the LED in my mouse goes off at the time of freeze, but trying to boot without the mouse connected produces the same result.

  • Find and Replace several several different values all at once

    - by matt
    I have a file with multiple instances of Text_1 and Text1 and I need to replace both those strings with Text_A and TextB respectively. Currently I'm doing two Find and Replace functions on each file one that finds Text_1 and replaces it with Text_A and the other that finds Text1 and replaces it with TextB. Is there any way to do this all at once instead of having to run "Find and Replace" twice? I am using Dreamweaver CS3, but I also have Notepad++, regular Notepad, OO Writer, MS Word if those will be easier. Ideally I could do this in Dreamweaver or Notepad++ but I'm open to downloading something else to get the job done. I'd prefer not to have to do any command line stuff or create a batch file (while I'm aware of it, I don't understand it really). Edit: In case the above description isn't clear, let me explain it this way... I want to run Find & Replace 1 time in 1 document and I want it to do ALL of the following during that one Find & Replace instance: Find: Text_1 and Replace with: Text_A Find: Text1 and Replace with: TextB I am not trying to do a Find and Replace across several documents.

  • JD Edwards... call C#?

    - by rbobby
    Hey all, I know very little about JD Edwards. I have a client asking how to call an API we supply (as COM, C#, REST) from JD Edwards. I'm not getting much in terms of high quality answers from their tech guy... so I thought I'd ask here. Can JD Edwards call C#? Can JD Edwards call Java? Can JD Edwards call a Unix scipt? Can anyone point me towards anything useful in terms of developer/customization documentation? Thanks!

  • Integrating Fedex and UPS into Rails Apps

    - by MikeH
    I'm working on integrating a shipping solution into a Rails ecommerce app. We're only going to use one shipping provider. So the question is: Fedex or UPS? I'm wondering what Rails developers think about the tech side of this question. What do you think about the APIs, ease of integration, focus on developer's needs between Fedex and UPS? I was leaning towards Fedex, but from looking at the developers resources sections of both sites, it seems that UPS might be more developer friendly. Also, I'm going to be using Shopify's active_shipping gem: http://github.com/Shopify/active_shipping And I also based my app off the Spree Ecommerce solution, but I don't think that's particularly relevant to the question. Spree wrote a wrapper to integrate active_shipping with the Spree system. I gave away all my points, so SO wont' let me post another link in this question. But if you google "Spree active-shipping", their wrapper on github is the first result. Thanks.
