• ASP, sorting database with conditions using multiple columns...

  - by Mitch

  First of all, I'm still working in classic ASP (vbScript) with an MS Access Database. And, yes I know its archaic, but I'm still hopeful I can do this! So now to my problem: Take the following table as an example: PROJECTS ContactName StartDate EndDate Complete Mitch 2009-02-13 2011-04-23 No Eric 2006-10-01 2008-11-15 Yes Mike 2007-05-04 2009-03-30 Yes Kyle 2009-03-07 2012-07-08 No Using ASP (with VBScript), and an MS Access Database as the backend, I’d like to be able to sort this table with the following logic: I would like to sort this table by date, however, depending on whether a given project is complete or not I would like it to use either the “StartDate” or “EndDate” as the reference for a particular row. So to break it down further, this is what I’m hoping to achieve: For PROJECTS where Complete = “Yes”, reference “EndDate” for the purpose of sorting. For PROJECTS where Complete = “No”, reference “StartDate” for the purpose of sorting. So, if I were to sort the above table following these rules, the output would be: PROJECTS ContactName StartDate EndDate Complete 1 Eric 2006-10-01 2008-11-15* Yes 2 Mitch 2009-02-13* 2011-04-23 No 3 Kyle 2009-03-07* 2012-07-08 No 4 Mike 2007-05-04 2009-03-30* Yes *I’ve put a star next to the date that should be used for the sort in the table above. NOTE: This is actually a simplified version of what I really need to do, but I think that if I could just figure this out, I’ll be able to do the rest on my own. ANY HELP IS GREATLY APPRECIATED; I’VE BEEN STRUGGLING WITH THIS FOR FAR TOO LONG NOW! Thank you!

• Cannot access a very specific site from my router

  - by DJDarkViper

  This is a problem for me because this site is important to me. It's MY website. And sadly my email is hosted on my site (which I cant access either) When I try to access my website when connected to my Linksys E3000 router, these days it simply just doesn't go through. When I ping it, its all Request Timed Out, and when I tracert C:\Users\Kyle>tracert blackjaguarstudios.com Tracing route to blackjaguarstudios.com [199.188.204.228] over a maximum of 30 hops: 1 <1 ms <1 ms <1 ms CISCO26565 [192.168.1.1] 2 16 ms 15 ms 11 ms 11.4.64.1 3 11 ms 9 ms 11 ms rd1cs-ge1-2-1.ok.shawcable.net [64.59.169.2] 4 20 ms 21 ms 22 ms 66.163.76.98 5 37 ms 36 ms 35 ms rc1nr-tge0-9-2-0.wp.shawcable.net [66.163.77.54] 6 112 ms 84 ms 85 ms rc2ch-pos9-0.il.shawcable.net [66.163.76.174] 7 86 ms 89 ms 90 ms rc4as-ge12-0-0.vx.shawcable.net [66.163.64.46] 8 90 ms 84 ms 85 ms eqix.xe-3-3-0.cr2.iad1.us.nlayer.net [206.223.115.61] 9 97 ms 97 ms 99 ms xe-3-3-0.cr1.atl1.us.nlayer.net [69.22.142.105] 10 128 ms 128 ms 126 ms ae1-40g.ar1.atl1.us.nlayer.net [69.31.135.130] 11 101 ms 97 ms 96 ms as16626.xe-2-0-5-102.ar1.atl1.us.nlayer.net [69.31.135.46] 12 100 ms 97 ms 197 ms 6509-sc1.abstractdns.com [207.210.114.166] 13 * * * Request timed out. 14 * * * Request timed out. 15 * * * Request timed out. 16 * * * Request timed out. 17 * * * Request timed out. 18 * * * Request timed out. 19 * * * Request timed out. 20 * * * Request timed out. 21 * * * Request timed out. 22 * * * Request timed out. 23 * * * Request timed out. 24 * * * Request timed out. 25 * * * Request timed out. 26 * * * Request timed out. 27 * * * Request timed out. 28 * * * Request timed out. 29 * * * Request timed out. 30 * * * Request timed out.

So I'm at a bit of a loss what to do here, as NO device (Computers, Laptops, Tablets, Phones, PS3/ 360, etc) can access my site or its features, so it's not just my computer either. But every other site is just fine. When I connect to my neighbors router, the site comes up just fine. And shes with SHAW as well. What should I do?!

• Why would my 15" MacBook Pro suddenly ask me to Hard Quit while I was in a browser?

  - by flathead27ford

  I was in Firefox looking at a search I had performed in eBay and all of a sudden, the screen grayed out starting from the top down. In the middle of the screen was a box with about 5 different languages saying I had to hard quit my computer. I tried other keys on my computer and nothing was working so I hard quit and restarted. Can anyone tell me why this happened? Cheers, Kyle

• Silverlight Firestarter Wrap Up and WCF RIA Services Talk Sample Code

  - by dwahlin

  I had a great time attending and speaking at the Silverlight Firestarter event up in Redmond on December 2, 2010. In addition to getting a chance to hang out with a lot of cool people from Microsoft such as Scott Guthrie, John Papa, Tim Heuer, Brian Goldfarb, John Allwright, David Pugmire, Jesse Liberty, Jeff Handley, Yavor Georgiev, Jossef Goldberg, Mike Cook and many others, I also had a chance to chat with a lot of people attending the event and hear about what projects they’re working on which was awesome. If you didn’t get a chance to look through all of the new features coming in Silverlight 5 check out John Papa’s post on the subject. While at the Silverlight Firestarter event I gave a presentation on WCF RIA Services and wanted to get the code posted since several people have asked when it’d be available. The talk can be viewed by clicking the image below. Code from the talk follows as well as additional links. I had a few people ask about the green bracelet on my left hand since it looks like something you’d get from a waterpark. It was used to get us access down a little hall that led backstage and allowed us to go backstage during the event. I thought it looked kind of dorky but it was required to get through security. Sample Code from My WCF RIA Services Talk (To login to the 2 apps use “user” and “P@ssw0rd”. Make sure to do a rebuild of the projects in Visual Studio before running them.) View All Silverlight Firestarter Talks and Scott Guthrie’s Keynote WCF RIA Services SP1 Beta for Silverlight 4 WCF RIA Services Code Samples (including some SP1 samples) Improved binding support in EntitySet and EntityCollection with SP1 (Kyle McClellan’s Blog) Introducing an MVVM-Friendly DomainDataSource: The DomainCollectionView (Kyle McClellan’s Blog) I’ve had the chance to speak at a lot of conferences but never with as many cameras, streaming capabilities, people watching live and overall hype involved. Over 1000 people registered to attend the conference in person at the Microsoft campus and well over 15,000 to watch it through the live stream.  The event started for me on Tuesday afternoon with a flight up to Seattle from Phoenix. My flight was delayed 1 1/2 hours (I seem to be good at booking delayed flights) so I didn’t get up there until almost 8 PM. John Papa did a tech check at 9 PM that night and I was scheduled for 9:30 PM. We basically plugged in my laptop backstage (amazing number of servers, racks and audio devices back there) and made sure everything showed up properly on the projector and the machines recording the presentation. In addition to a dedicated show director, there were at least 5 tech people back stage and at least that many up in the booth running lights, audio, cameras, and other aspects of the show. I wish I would’ve taken a picture of the backstage setup since it was pretty massive – servers all over the place. I definitely gained a new appreciation for how much work goes into these types of events. Here’s what the room looked like right before my tech check– not real exciting at this point. That’s Yavor Georgiev (who spoke on WCF Services at the Firestarter) in the background. We had plenty of monitors to reference during the presentation. Two monitors for slides (right and left side) and a notes monitor. The 4th monitor showed the time and they’d type in notes to us as we talked (such as “You’re over time!” in my case since I went around 4 minutes over :-)). Wednesday morning I went back on campus at Microsoft and watched John Papa film a few Silverlight TV episodes with Dave Campbell and Ryan Plemons.   Next I had the chance to watch the dry run of the keynote with Scott Guthrie and John Papa. We were all blown away by the demos shown since they were even better than expected. Starting at 1 PM on Wednesday I went over to Building 35 and listened to Yavor Georgiev (WCF Services), Jaime Rodriguez (Windows Phone 7), Jesse Liberty (Data Binding) and Jossef Goldberg and Mike Cook (Silverlight Performance) give their different talks and we all shared feedback with each other which was a lot of fun. Jeff Handley from the RIA Services team came afterwards and listened to me give a dry run of my WCF RIA Services talk. He had some great feedback that I really appreciated getting. That night I hung out with John Papa and Ward Bell and listened to John walk through his keynote demos. I also got a sneak peak of the gift given to Dave Campbell for all his work with Silverlight Cream over the years. It’s a poster signed by all of the key people involved with Silverlight: Thursday morning I got up fairly early to get to the event center by 8 AM for speaker pictures. It was nice and quiet at that point although outside the room there was a huge line of people waiting to get in.     At around 8:30 AM everyone was let in and the main room was filled quickly. Two other overflow rooms in the Microsoft conference center (Building 33) were also filled to capacity. At around 9 AM Scott Guthrie kicked off the event and all the excitement started! From there it was all a blur but it was definitely a lot of fun. All of the sessions for the Silverlight Firestarter were recorded and can be watched here (including the keynote). Corey Schuman, John Papa and I also released 11 lab exercises and associated videos to help people get started with Silverlight. Definitely check them out if you’re interested in learning more!

• Oracle collaborates with leading IT vendors on Cloud Management Standards

  - by Anand Akela

  During the last couple of days, two key specifications for cloud management standards have been announced. Oracle collaborated with leading technology vendors from the IT industry on both of these cloud management specifications. One of the specifications focuses "Infrastructure as a Service" ( IaaS )  cloud service model , while the other specification announced today focuses on "Platform as a Service" ( PaaS ) cloud service model. Please see The NIST Definition of Cloud Computing to learn more about IaaS and PaaS . Earlier today Oracle , CloudBees, Cloudsoft, Huawei, Rackspace, Red Hat, and Software AG   announced the Cloud Application Management for Platforms (CAMP) specification that will be submitted to Organization for the Advancement of Structured Information Standards (OASIS) for development of an industry standard, in an effort to help ensure interoperability for deploying and managing applications across cloud environments.  Typical PaaS architecture - Source : CAMP specification The CAMP specification defines the artifacts and APIs that need to be offered by a PaaS cloud to manage the building, running, administration, monitoring and patching of applications in the cloud. Its purpose is to enable interoperability among self-service interfaces to PaaS clouds by defining artifacts and formats that can be used with any conforming cloud and enable independent vendors to create tools and services that interact with any conforming cloud using the defined interfaces. Cloud vendors can use these interfaces to develop new PaaS offerings that will interact with independently developed tools and components. In a separate cloud standards announcement yesterday, the Distributed Management Task Force ( DMTF ), the organization bringing the IT industry together to collaborate on systems management standards development, validation, promotion and adoption, released the new Cloud Infrastructure Management Interface (CIMI) specification. Oracle collaborated with various technology vendors and industry organizations on this specification. CIMI standardizes interactions between cloud environments to achieve interoperable cloud infrastructure management between service providers and their consumers and developers, enabling users to manage their cloud infrastructure use easily and without complexity. DMTF developed CIMI as a self-service interface for infrastructure clouds ( IaaS focus ) , allowing users to dynamically provision, configure and administer their cloud usage with a high-level interface that greatly simplifies cloud systems management. Mark Carlson, Principal Cloud Strategist at Oracle provides more details about CAMP  and CIMI his blog . Stay Connected: Twitter |  Face book |  You Tube |  Linked in |  Newsletter

• Cloud Application Management for Platforms

  - by user756764

  Today Oracle, along with CloudBees, Cloudsoft, Huawei, Rackspace, Red Hat, and Software AG, published the Cloud Application Management for Platforms (CAMP) specification. This spec deals with application management in the context of PaaS. It defines a model (consisting of a set resources and their relationships), a REST-based API for manipulating that model, and a packaging format for getting applications (and their attendant metadata) into and out of the platform. My colleague, Mark Carlson, has already provided an excellent writeup on the spec here. The following, additional points bear emphasizing: CAMP is language, framework and platform neutral; it should be equally applicable to the task of deploying and managing Ruby on Rails applications as Java/Spring applications (as Node.js applications, etc.) CAMP only covers the interactions between a Cloud Consumer and a Cloud Provider (using the definitions of these terms provided in the NIST Cloud Computing Reference Architecture). The internal APIs used by the Cloud Provider to, for example, deploy additional platform services (e.g. a new message queuing service) are out of CAMP's scope. CAMP supports the management of the entire lifecycle of the application (e.g. start/stop, suspend/resume, etc.) not just the deployment of the components that make up the application. Complexity is the antithesis of interoperability. One of CAMP's goals is to be as broadly interoperable as possible. To this end, the authors of CAMP tried to "make things as simple as possible, but no simpler". For example, JSON is the only serialization format used in the spec (although Providers can extend this to support additional serialization formats such as XML). It remains to be seen whether we can preserve this simplicity as the spec is processed by OASIS. So far, those who have indicated an interest in collaborating on the spec seem to be of a like mind with regards to the need for simplicity. The flip side to simplicity is the knowledge that you undoubtedly missed something that is important to someone. To make up for this, CAMP is designed to be extensible. The idea is to ship what we know will work, allow implementers to extend the spec, then re-factor the spec to incorporate the most popular extensions. Anyone interested in this effort, particularly those of you using PaaS-level services, is encouraged to join the forthcoming OASIS TC. As you may have noticed, CAMP is a bit of a departure from some of the more monolithic management standards that have preceded it. The idea is to develop simple, discrete standards targeted to address specific interoperability and portability problems and tie these standards together with common patterns based on REST and HATEOAS. I'm excited to see how this idea plays out.

• What NIS maps are needed for OSX 10.6 to authenticate?

  - by Kyle__

  What NIS maps are necessary for OSX 10.6 to authenticate? I have an ubuntu-sever sharing NIS, and from the OSX client, ypcat passwd, ypcat group and (as root) ypcat shadow.byname all work, and return the correct info. If I type groups kyle (a user in NIS, but not on the local machine), I get all the correct group information. The only thing that doesn't work, is logging in. (And yes, if I point an ubuntu box to that NIS server, everything authenticates off of it just fine).

• Is “Application Programming Interface” a bad name?

  - by Taylor Hawkes

  Application programming interface seems like a bad name for what it is. Is there a reason it was named such? I understand that people used to call them Advanced Programming Interfaces and then renamed to Application Programming Interface. Is that why it is poorly named? Why is it not named Application (to) Programmer Interface. I guess I'm just confused of the meaning behind that name? I write more about my confusion around the name here: BREAKING DOWN THE WORD “APPLICATION PROGRAMMING INTERFACE” This is a very confusing word. We mostly understand what the word Interface means, but “Application Programming”, what even is that. Honestly I'm confused. Is that suppose to be two words like “Application”, “Programming” and then the “Interface” is suppose to mean between the two? Like would a “Computer Human Interface” be an interface between a “Computer” and a “Human” (monitor , keyboard, mouse ) or is a “Computer Human” a real thing - perhaps the terminator. So a CHI is our boy Kyle Reese who is the only way we are able to work with the computer human. I think more likely “Application Programming Interface” was simply poorly named and doesn't really make sense. It was originally called an “Advanced Programming Interface” , but perhaps being a bit to ostentatious merged into the now wildly accepted “Application Programming Interface”. So now, not wanting to change an acronym has confused the living heck out everyone.... Any thoughts or clarification would be great, I'm giving a lecture on this topic in a month, so I would prefer not to BS my way through it.

• Oracle UCM GET_SEARCH_RESULTS service with full text search

  - by Lyudmil Pelov

  Newly I was working on portlet which should be able to do full text search through the UCM documents and I was experimenting with the Ridc and also with the CIS API's. There are some ticks you may take care of, for example using quotes is a very spacial case and most of situations UCM will throw an exception if you not use them well. So during my tests I was able to develop one solution which works very well for me doing full text search and here is it: final IdcClientManager idcManager = new IdcClientManager(); final IdcClient idcClient = idcManager.createClient("idc://127.0.0.1:4444"); final IdcContext idcContext = new IdcContext("sysadmin"); final DataBinder binder = idcClient.createBinder(); // populate the binder with the parameters binder.putLocal ("IdcService", "GET_SEARCH_RESULTS"); binder.putLocal ("QueryText", "dDocFullText <substring> <qsch>"+yourSearchWordOrWords+"</qsch>");  binder.putLocal ("SearchEngineName", "databasefulltext"); binder.putLocal ("ResultCount", "20"); // execute the request ServiceResponse response = idcClient.sendRequest (idcContext, binder); // get the binder DataBinder serverBinder = response.getResponseAsBinder (); DataResultSet resultSet = serverBinder.getResultSet ("SearchResults"); // loop over the results for (DataObject dataObject : resultSet.getRows ()) { System.out.println ("Title is: " + dataObject.get ("dDocTitle")); System.out.println ("Author is: " + dataObject.get ("dDocAuthor")); }Nothing special so far except the line which declares the full text search. To be able to proceed with the full text search you have to use dDocFullText attribute inside the search query. The tag <substring> is the same as 'like'. Also you have to put your searching string or words in quotes which could be a problem sometime, so I used the tag <qsch>. Using this tag you can have quotes now inside you searching string without to break the code and get parsing exceptions.To be able to test the example, you do have to enable full text search inside UCM. To do this follow the steps for example from this blog here and then re-index the documents in UCM.There is also one very nice article about how to define UCM queries if want to replace the full text search with something more specific, you can read this article from Kyle's Blog here.

• Rsync: General file/folder synchronization

  - by Rey Leonard Amorato

  I have a file server, which is in-charge of pulling a folder tree from multiple workstations on a daily basis. My current method for this is by using rsync, (which works pretty well provided directory names and/or files remain the same) however, when files are renamed or moved about within subdir1, rsync will copy them over to the server, creating duplicates. I have to manually find and delete extraneous files/folders that had been left on the server during previous syncs. Note that I cannot use rsync's --delete flag because any sync from a workstation will then mirror that particular folder tree, instead of merging them to the server. Visual diagram: Server: Workstation1 Workstation2 Workstation(n) Folder* Folder* Folder* Folder* -subdir1 -subdir1 -subdir1 -subdir(n) -file1 -file1 -file2 -file(n) -file2 -file(n) Is there a simple script (preferably in bash, nothing fancy) that can accomplish the deletion of the extraneous files/folders in the event a file is renamed or moved to a different subdir? Is there a different program, much like rsync that can accomplish this task autonomously and in a much simpler manner? I have looked at unison, but I did not like the fact that it keeps a local database for the syncing info. Any tips at all as to how I am supposed to tackle this? Thank you in advanced for your help. EDIT: I have tried unison just recently and I can safely say it is out of the question now. unison is a bi-directional synchronization tool and from my testing, it mirrors the files existing on the server to all workstations. - This is unwanted. preferably, i would want files/folders to stay within their respective workstations and just merge to the server. AKA uni-directional sync; but with renames/moves propagated to the server. I might have to look into Git/Mercurial/Bazaar as mentioned by kyle, but still unsure if they are fit for the job.

• How to force a login for an administrator when using Remote Desktop Connection and fast user switching enabled?

  - by brett rogers

  Scenario: I am at work. I want to remote desktop into my machine at home. Problem is, my 5-year-old daughter is playing games on Starfall.com (or something similar) on her (non-admin) account. When I attempt to connect I see this message: Another user is currently logged on to this computer. If you continue, this user has to disconnect from this computer. Do you want to continue? I click Yes and then see Please wait for 'UserName' to respond This presents my daughter with an Allow/Disallow dialog on whether to let me connect. She clicks Disallow (or No or whatever it says) and then I see 'UserName' has denied your request Question: How can I force my account to log in and disconnect her session? Additional Info: My account is an administrator account. My daughter's account is a non-administrator account. Home machine is Windows 7 Pro with fast user switching enabled. Turning off fast user switching is not an option (Kyle pointed out in his answer that turning it off would allow the admin to force another user off). I would keep fast user switching's ability to change accounts without closing the previous account's session over being able to force myself to connect.

• Do background processes get a SIGHUP when logging off?

  - by Massimo

  This is a followup to this question. I've run some more tests; looks like it really doesn't matter if this is done at the physical console or via SSH, neither does this happen only with SCP; I also tested it with cat /dev/zero > /dev/null. The behaviour is exactly the same: Start a process in the background using & (or put it in background after it's started using CTRL-Z and bg); this is done without using nohup. Log off. Log on again. The process is still there, running happily, and is now a direct child of init. I can confirm both SCP and CAT quits immediately if sent a SIGHUP; I tested this using kill -HUP. So, it really looks like SIGHUP is not sent upon logoff, at least to background processes (can't test with a foreground one for obvious reasons). This happened to me initially with the service console of VMware ESX 3.5 (which is based on RedHat), but I was able to replicate it exactly on CentOS 5.4. The question is, again: shouldn't a SIGHUP be sent to processes, even if they're running in background, upon logging off? Why is this not happening? Edit I checked with strace, as per Kyle's answer. As I was expecting, the process doesn't get any signal when logging off from the shell where it was launched. This happens both when using the server's console and via SSH.

• HAProxy crashes on all requests in 1.5-dev12

  - by Daniel Hough

  I'm having an issue where HAProxy is crashing with no explanation when I switch from 1.4.12 to 1.5-dev12. The reason I'm switching is for the SSL offloading. My config file doesn't have any errors, it's quite simple and it works well with 1.4 - but for some reason when I run it with 1.5-dev12 I see the logs noting that the two backends I have have been set up, and then when I hit one of the frontends, I get an HTTP 400 in the browser and suddenly HAProxy isn't running anymore when I check. I understand that a common workaround to the lack of SSL support for HAProxy is to use Stud, and I may go with that since I am in need of an SSL solution for my service, but before I dele into that world I thought I might see if anybody has experienced the same problems and might know how to fix it. The server is Ubuntu 10.04 and I followed the make instructions on the Exceliance blog here. EDIT: On the advice of Kyle Brandt, I did a bit more investigation. I attached gdb to the haproxy process and when the crash occurred this is what I got: Program received signal SIGSEGV, Segmentation fault. 0x0804e5c2 in dequeue_all_listeners (list=0x9e1a418) at src/protocols.c:184 184 list_for_each_entry_safe(listener, l_back, list, wait_queue) { P.S. HAProxy is awesome, so thank you Exceliance for providing us with something so useful :)

• Failling install Ralink RT5592 driver on Ubuntu 14.04 LTS

  - by atisou

  My problem concerns the installation of a wi-fi driver (RT5592) for my new wi-fi adapter (PCE-N53) on my newly built computer. Basically, I don't manage to get the driver installed and therefore I cannot get the wifi to work. I know I am not the only one having this issue this year, between RT5592 driver and Ubuntu 14.04 LTS, in one way or the other. Is there anybody who has ever been able to fix this problem? It does not look like on all the posts I have been through... Following an answer to a same problem as mine (I was getting the same error message as Christopher Kyle Horton of "incompatible types" etc), I have applied the instructions and done the editings in a script as suggested by Paul B. Unfortunately I still do get error/warnings message (a different one this time) at the end of the make and the wi-fi still does not work. Below is a snapshot of the end of the message: In file included from /home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/include/os/rt_linux.h:31:0, from /home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/include/rtmp_os.h:44, from /home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/include/rtmp_comm.h:69, from /home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/os/linux/../../os/linux/pci_main_dev.c:31: include/linux/module.h:88:32: error: ‘__mod_pci_device_table’ aliased to undefined symbol ‘rt2860_pci_tbl’ extern const struct gtype##_id __mod_##gtype##_table \ ^ include/linux/module.h:146:3: note: in expansion of macro ‘MODULE_GENERIC_TABLE’ MODULE_GENERIC_TABLE(type##_device,name) ^ /home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/os/linux/../../os/linux/pci_main_dev.c:73:1: note: in expansion of macro ‘MODULE_DEVICE_TABLE’ MODULE_DEVICE_TABLE(pci, rt2860_pci_tbl); ^ cc1: some warnings being treated as errors make[2]: *** [/home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/os/linux/../../os/linux/pci_main_dev.o] Error 1 make[1]: *** [_module_/home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/os/linux] Error 2 make[1]: Leaving directory `/usr/src/linux-headers-3.13.0-32-generic' make: *** [LINUX] Error 2 The full pastebin data: paste.ubuntu.com/8088834/ It looks from the message that one would need to edit manually some of/other scripts in the driver package, as did Paul B suggest in one case. But I have no idea how to do that. Here is the driver package of the wifi adapter: www.asus.com/uk/Networking/PCEN53/HelpDesk_Download/ My system is as following: OS: ubuntu 14.04 LTS wi-fi card: Asus PCE-N53 motherboard: Asus KCMA-D8 processor: AMD Opteron 4228 HE kernel: 3.13.0-32-generic Following this info from chili555 in here, below are some extra info about my system: lspci -nn | grep 0280 gives 04:00.0 Network controller [0280]: Ralink corp. RT5592 PCI2 Wireless Network Adapater [1814:5592] and sudo apt-get install linux-headers-generic returns linux-headers-generic is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. If this is a kernel version (I have 3.13.0-32-generic) incompatibility issue with the driver as chilli555 suggests (the README file in the driver package says indeed it is compatible with kernel 2.6), how could one trick this around to make it work? that should be possible right? On ubuntu forums, the patches proposed dont work (leads the computer to freeze). Basically: is there anybody out there who has ever been able to make a PCE-N53 work on Ubuntu 14.04 LTS (kernel 3.13)? how shall I edit the driver package to make it work for my kernel?

• WebCenter Content (WCC) Trace Sections

  - by Kevin Smith

  Kyle has a good post on how to modify the size and number of WebCenter Content (WCC) trace files. His post reminded me I have been meaning to write a post on WCC trace sections for a while. searchcache - Tells you if you query was found in the WCC search cache. searchquery - Shows the processing of the query as it is converted form what the user submitted to the end query that will be sent to the database. Shows conversion from the universal query syntax to the syntax specific to the search solution WCC is configured to use. services (verbose) - Lists the filters that are called for each service. This will let you know what filters are available for each service and will also tell you what filters are used by WCC add-on components and any custom components you have installed. The How To Component Sample has a list of filters, but it has not been updated since 7.5, so it is a little outdated now. With each new release WCC adds more filters. If you have a filter that has no code attached to it you will see output like this: services/6    09.25 06:40:26.270    IdcServer-423    Called filter event computeDocName with no filter plugins registered When a WCC add-on or custom component uses a filter you will see trace output like this: services/6    09.25 06:40:26.275    IdcServer-423    Calling filter event postValidateCheckinData on class collections.CollectionValidateCheckinData with parameter postValidateCheckinDataservices/6    09.25 06:40:26.275    IdcServer-423    Calling filter event postValidateCheckinData on class collections.CollectionFilters with parameter postValidateCheckinData As you can see from this sample output it is possible to have multiple code points using the same filter. systemdatabase - Dumps the database call AFTER it executes. This can be somewhat troublesome if you are trying to track down some weird database problems. We had a problem where WCC was getting into a deadlock situation. We turned on the systemdatabase trace section and thought we had the problem database call, but it turned out since it printed out the database call after it was executed we were looking at the database call BEFORE the one causing the deadlock. We ended up having to turn on tracing at the database level to see the database call WCC was making that was causing the deadlock. socketrequests (verbose) - dumps the actual messages received and sent over the socket connection by WCC for a service. If you have gzip enabled you will see junk on the response coming back from WCC. For debugging disable the gzip of the WCC response.Here is an example of the dump of the request for a GET_SEARCH_RESULTS service call. socketrequests/6 09.25 06:46:02.501 IdcServer-6 request: REMOTE_USER=sysadmin.USER-AGENT=Java;.Stel socketrequests/6 09.25 06:46:02.501 IdcServer-6 request: lent.CIS.11g.CONTENT_TYPE=text/html.HEADER socketrequests/6 09.25 06:46:02.501 IdcServer-6 request: _ENCODING=UTF-8.REQUEST_METHOD=POST.CONTEN socketrequests/6 09.25 06:46:02.501 IdcServer-6 request: T_LENGTH=270.HTTP_HOST=CIS.$$$$.NoHttpHead socketrequests/6 09.25 06:46:02.501 IdcServer-6 request: ers=0.IsJava=1.IdcService=GET_SEARCH_RESUL socketrequests/6 09.25 06:46:02.501 IdcServer-6 request: [email protected] socketrequests/6 09.25 06:46:02.501 IdcServer-6 request: calData.SortField=dDocName.ClientEncoding= socketrequests/6 09.25 06:46:02.501 IdcServer-6 request: UTF-8.IdcService=GET_SEARCH_RESULTS.UserTi socketrequests/6 09.25 06:46:02.501 IdcServer-6 request: meZone=UTC.UserDateFormat=iso8601.SortDesc socketrequests/6 09.25 06:46:02.501 IdcServer-6 request: =ASC.QueryText=dDocType..matches..`Documen socketrequests/6 09.25 06:46:02.501 IdcServer-6 request: t`.@end. userstorage, jps - Provides trace details for user authentication and authorization. Includes information on the determination of what roles and accounts a user has access to. In 11g a new trace section, jps, was added with the addition of the JpsUserProvider to communicate with WebLogic Server. The WCC developers decide when to use the verbose option for their trace output, so sometime you need to try verbose to see what different information you get. One of the things I would always have liked to see if the ability to turn on verbose output selectively for individual trace sections. When you turn on verbose output you get it for all trace sections you have enabled. This can quickly fill up your trace files with a lot of information if you have the socket trace section turned on.

• Book Review: Brownfield Application Development in .NET

  - by DotNetBlues

  I recently finished reading the book Brownfield Application Development in .NET by Kyle Baley and Donald Belcham.  The book is available from Manning.  First off, let me say that I'm a huge fan of Manning as a publisher.  I've found their books to be top-quality, over all.  As a Kindle owner, I also appreciate getting an ebook copy along with the dead tree copy.  I find ebooks to be much more convenient to read, but hard-copies are easier to reference. The book covers, surprisingly enough, working with brownfield applications.  Which is well and good, if that term has meaning to you.  It didn't for me.  Without retreading a chunk of the first chapter, the authors break code bases into three broad categories: greenfield, brownfield, and legacy.  Greenfield is, essentially, new development that hasn't had time to rust and is (hopefully) being approached with some discipline.  Legacy applications are those that are more or less stable and functional, that do not expect to see a lot of work done to them, and are more likely to be replaced than reworked. Brownfield code is the gray (brown?) area between the two and the authors argue, quite effectively, that it is the most likely state for an application to be in.  Brownfield code has, in some way, been allowed to tarnish around the edges and can be difficult to work with.  Although I hadn't realized it, most of the code I've worked on has been brownfield.  Sometimes, there's talk of scrapping and starting over.  Sometimes, the team dismisses increased discipline as ivory tower nonsense.  And, sometimes, I've been the ignorant culprit vexing my future self. The book is broken into two major sections, plus an introduction chapter and an appendix.  The first section covers what the authors refer to as "The Ecosystem" which consists of version control, build and integration, testing, metrics, and defect management.  The second section is on actually writing code for brownfield applications and discusses object-oriented principles, architecture, external dependencies, and, of course, how to deal with these when coming into an existing code base. The ecosystem section is just shy of 140 pages long and brings some real meat to the matter.  The focus on "pain points" immediately sets the tone as problem-solution, rather than academic.  The authors also approach some of the topics from a different angle than some essays I've read on similar topics.  For example, the chapter on automated testing is on just that -- automated testing.  It's all well and good to criticize a project as conflating integration tests with unit tests, but it really doesn't make anyone's life better.  The discussion on testing is more focused on the "right" level of testing for existing projects.  Sometimes, an integration test is the best you can do without gutting a section of functional code.  Even if you can sell other developers and/or management on doing so, it doesn't actually provide benefit to your customers to rewrite code that works.  This isn't to say the authors encourage sloppy coding.  Far from it.  Just that they point out the wisdom of ignoring the sleeping bear until after you deal with the snarling wolf. The other sections take a similarly real-world, workable approach to the pain points they address.  As the section moves from technical solutions like version control and continuous integration (CI) to the softer, process issues of metrics and defect tracking, the authors begin to gently suggest moving toward a zero defect count.  While that really sounds like an unreasonable goal for a lot of ongoing projects, it's quite apparent that the authors have first-hand experience with taming some gruesome projects.  The suggestions are grounded and workable, and the difficulty of some situations is explicitly acknowledged. I have to admit that I started getting bored by the end of the ecosystem section.  No matter how valuable I think a good project manager or business analyst is to a successful ALM, at the end of the day, I'm a gear-head.  Also, while I agreed with a lot of the ecosystem ideas, in theory, I didn't necessarily feel that a lot of the single-developer projects that I'm often involved in really needed that level of rigor.  It's only after reading the sidebars and commentary in the coding section that I had the context for the arguments made in favor of a strong ecosystem supporting the development process.  That isn't to say that I didn't support good product management -- indeed, I've probably pushed too hard, on occasion, for a strong ALM outside of just development.  This book gave me deeper insight into why some corners shouldn't be cut and how damaging certain sins of omission can be. The code section, though, kept me engaged for its entirety.  Many technical books can be used as reference material from day one.  The authors were clear, however, that this book is not one of these.  The first chapter of the section (chapter seven, over all) addresses object oriented (OO) practices.  I've read any number of definitions, discussions, and treatises on OO.  None of the chapter was new to me, but it was a good review, and I'm of the opinion that it's good to review the foundations of what you do, from time to time, so I didn't mind. The remainder of the book is really just about how to apply OOP to existing code -- and, just because all your code exists in classes does not mean that it's object oriented.  That topic has the potential to be extremely condescending, but the authors miraculously managed to never once make me feel like a dolt or that they were wagging their finger at me for my prior sins.  Instead, they continue the "pain points" and problem-solution presentation to give concrete examples of how to apply some pretty academic-sounding ideas.  That's a point worth emphasizing, as my experience with most OO discussions is that they stay in the academic realm.  This book gives some very, very good explanations of why things like the Liskov Substitution Principle exist and why a corporate programmer should even care.  Even if you know, with absolute certainty, that you'll never have to work on an existing code-base, I would recommend this book just for the clarity it provides on OOP. This book goes beyond just theory, or even real-world application.  It presents some methods for fixing problems that any developer can, and probably will, encounter in the wild.  First, the authors address refactoring application layers and internal dependencies.  Then, they take you through those layers from the UI to the data access layer and external dependencies.  Finally, they come full circle to tie it all back to the overall process.  By the time the book is done, you're left with a lot of ideas, but also a reasonable plan to begin to improve an existing project structure. Throughout the book, it's apparent that the authors have their own preferred methodology (TDD and domain-driven design), as well as some preferred tools.  The "Our .NET Toolbox" is something of a neon sign pointing to that latter point.  They do not beat the reader over the head with anything resembling a "One True Way" mentality.  Even for the most emphatic points, the tone is quite congenial and helpful.  With some of the near-theological divides that exist within the tech community, I found this to be one of the more remarkable characteristics of the book.  Although the authors favor tools that might be considered Alt.NET, there is no reason the advice and techniques given couldn't be quite successful in a pure Microsoft shop with Team Foundation Server.  For that matter, even though the book specifically addresses .NET, it could be applied to a Java and Oracle shop, as well.

• The maximum message size quota for incoming messages (65536) has been exceeded.

  - by DaleyKD

  My WCF Service has an OperationContract that accepts, as a parameter, an array of objects. This can potentially be quite large. After looking for fixes for Bad Request: 400, I found the real reason: the maximum message size. I know this question has been asked before in MANY places. I've tried what everyone says: "Increase the sizes in the client and server config files." I have. It still doesn't work. My Service's web.config: <system.serviceModel> <services> <service name="myService"> <endpoint name="myEndpoint" address="" binding="basicHttpBinding" bindingConfiguration="myBinding" contract="Meisel.WCF.PDFDocs.IPDFDocsService" /> </service> </services> <bindings> <basicHttpBinding> <binding name="myBinding" closeTimeout="00:11:00" openTimeout="00:11:00" receiveTimeout="00:15:00" sendTimeout="00:15:00" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" maxBufferPoolSize="2147483647" transferMode="Buffered" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true"> <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" /> <security mode="None" /> </binding> </basicHttpBinding> </bindings> <behaviors> <serviceBehaviors> <behavior> <serviceMetadata httpGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="true" /> <dataContractSerializer maxItemsInObjectGraph="2147483647" /> </behavior> </serviceBehaviors> </behaviors> <serviceHostingEnvironment multipleSiteBindingsEnabled="true" /> </system.serviceModel> My Client's app.config: <system.serviceModel> <bindings> <basicHttpBinding> <binding name="BasicHttpBinding_IPDFDocsService" closeTimeout="00:11:00" openTimeout="00:11:00" receiveTimeout="00:10:00" sendTimeout="00:11:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="2147483647" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true"> <readerQuotas maxDepth="32" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" /> <security mode="None"> <transport clientCredentialType="None" proxyCredentialType="None" realm="" /> <message clientCredentialType="UserName" algorithmSuite="Default" /> </security> </binding> </basicHttpBinding> </bindings> <client> <endpoint address="http://localhost:8451/PDFDocsService.svc" behaviorConfiguration="MoreItemsInObjectGraph" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IPDFDocsService" contract="PDFDocsService.IPDFDocsService" name="BasicHttpBinding_IPDFDocsService" /> </client> <behaviors> <endpointBehaviors> <behavior name="MoreItemsInObjectGraph"> <dataContractSerializer maxItemsInObjectGraph="2147483647" /> </behavior> </endpointBehaviors> </behaviors> </system.serviceModel> What can I possibly be missing or doing wrong? It's as though the service is ignoring what I typed in the maxReceivedBufferSize. Thanks in advance, Kyle UPDATE Here are two other StackOverflow questions where they never received an answer, either: http://stackoverflow.com/questions/2880623/maxreceivedmessagesize-adjusted-but-still-getting-the-quotaexceedexception-with http://stackoverflow.com/questions/2569715/wcf-maxreceivedmessagesize-property-not-taking
