• Taking too long to get skills for entry level programmer position [closed]

  - by greenonion

  I don't have the skills for an entry level position as a .Net programmer. I am trying to learn what I need but there is too much to learn and too little time. What can I do? About two months ago, I went to a job interview for an entry level C# .Net programming/consultant position in NYC. When I heard back from them, they told me that the knowledge gap between what I knew and what they needed me to know was too big and I might have been a better fit if I had 6 months of experience. This was the first interview that I went on since graduating college. before the interview, I read a book on visual C#. Turns out it wasn't a very good book and I was missing a lot of key areas of knowledge such as ADO.net SQL (I had learned some LINQ) A little bit about how memory is handled Multiple threaded programming, etc. Because the book wasn't very good, the stuff I did know, I didn't know very well. I felt crushed. I've applied for jobs to gain experience but when recruiters hear that I have no experience they lose interest. I figured that I can at least work on my knowledge. Since then, I read "SQL Essentials" to cover the SQL bit and I found a pretty awesome book that is good enough to clear up what's hazy in my mind and covers almost all of the extra topics. The book is "C# 4.0: The Complete Reference" by Herbert Schildt. I'm even learning a lot about the topics I was familiar with. For a month now I've been working my way through this beast of a book. However, gaining the knowledge I need is taking too long. I can't hold off not having a full-time job much longer. I'm not stupid and I'm studying constantly pouring through the book, asking questions on stackoverflow, referencing the C# specification, etc. I have made great progress but there is just too much ground to cover. I'm on chapter 12 which is about a 3rd through the book. To get an idea of what I know vs don't know, the table of contents is on amazon: http://www.amazon.com/C-4-0-The-Complete-Reference/dp/007174116X How on earth can someone know enough to function as a programmer in the real world? Can I try for a job in academia? Will I have time to finish learning the rest of the C# language or am I just un-hireable?

• iOS app with a lot of text

  - by rdurand

  I just asked a question on StackOverflow, but I'm thinking that a part of it belongs here, as questions about design pattern are welcomed by the faq. Here is my situation. I have developed almost completely a native iOS app. The last section I need to implement is all the rules of a sport, so that's a lot of text. It has one main level of sections, divided in subsections, containing a lot of structured text (paragraphs, a few pictures, bulleted/numbered lists, tables). I have absolutely no problem with coding, I'm just looking for advice to improve and make the best design pattern possible for my app. My first shot (the last one so far) was a UITableViewController containing the sections, sending the user to another UITableViewController with the subsections of the selected section, and then one strange last UITableViewController where the cells contain UITextViews, sections header help structure the content, etc. What I would like is your advice on how to improve the structure of this section. I'm perfectly ready to destroy/rebuild the whole thing, I'm really lost in my design here.. As I said on SO, I've began to implement a UIWebView in a UIViewController, showing a html page with JQuery Mobile to display the content, and it's fine. My question is more about the 2 views taking the user to that content. I used UITableViewControllers because that's what seemed the most appropriate for a structured hierarchy like this one. But that doesn't seem like the best solution in term of user experience.. What structure / "view-flow" / kind of presentation would you try to implement in my situation? As always, any help would be greatly appreciated! Just so you can understand better the hierarchy, with a simple example : -----> Section 1 -----> SubSection 1.1 -----> Content | -----> SubSection 1.2 -----> Content | -----> SubSection 1.3 -----> Content | | | UINavigationController -------> Section 2 -----> SubSection 2.1 -----> Content | -----> SubSection 2.2 -----> Content | -----> SubSection 2.3 -----> Content | -----> SubSection 2.4 -----> Content | -----> SubSection 2.5 -----> Content | -----> Section 3 -----> SubSection 3.1 -----> Content -----> SubSection 3.2 -----> Content |------------------| |--------------------| |-------------| 1 UITableViewController 3 UITableViewControllers 10 UIViewControllers (3 rows) (with different with a UIWebView number of rows)

• Should I use my own public API on my site (via JS)?

  - by newboyhun

  First of all, this question is far more different other 'public api questions' like this: Should a website use its own public API?, second, sorry for my English. You can find the question summarized at the bottom of this question. What I want to achieve is a big website with a public api, so who like programming (like me) and likes my website, can replicate my website's data with a much better approach (of course with some restrictions). Almost everything could be used by the public API. Because of this, I was thinking about making the whole website AJAX driven. There would be parts of the API which would be limited only to my website (domain), like login, registering. There would be only an INTERFACE on the client side, which would use the public and private API to make this interface working. The website would be ONLY CLIENT SIDE, well, I mean, the website would only use AJAX to use the api. How do I imagine this? The website would be like a mobile application, the application only sending a request to a webserver, which returns a json, the application parses it, and uses it to advance in the application. (e.g.: login) My thoughts: Pros: The whole website is built up by javascript, this means I don't need to transfer the html to the client, saving bandwidth. (I hope so) Anyone can use up the data of my website to make their own cool things. (Is this a con or pro? O_O) The public API is always in use, so I can see if there are any error. Cons: Without Javascript the website is unusable. The bad guys easily can load the server with requesting too much data (like Request Per Second 10000), but this can be countered via limiting this with some PHP code and logging. Probably much more work So the question in some words is: Should I build my website around my own api? Is it good to work only on the client side? Is this good for a big website? (e.x.: facebook, yeah facebook is a different story, but could it run with an 'architecture' like this?)

• Recommended learning path?

  - by stairmast0r

  First, my current standing: I know C++ at an.. advanced beginner level? I've gone through a book, I know the syntax well enough, I know a fair amount of standard library functions, and I've programmed some simple console stuff with it. I'd probably be able to program more with it if I knew how to structure a program, but I just can't seem to wrap my head around the whole concept of structuring something remotely complex. I've messed around with Java for a day or two, and the syntax was extremely easy to get the hang of, except that I didn't really know any functions. I'm plenty willing to learn, and to work hard to do so, but I don't really know where to go from here. Now, at the risk of sounding cliche, what I'd like to become is someone like the great three of id; Carmack, Romero, and Abrash. To be considered a genius. I believe anything can be learned, and nothing mentally limits anyone except lack of desire to learn. But I don't know how to learn this. They learned by doing, and making do with what resources they had. On the other hand, I have access to almost any books I want, access to the internet, and access to a more than capable computer and software. Should I learn more languages? Assembly? LISP? BASIC? Haskell? Should I dive straight into advanced topics like OpenGL? Or should I wait until I feel I've come closer to mastering the simpler things, like console programs, first? Should I follow tutorials? Should I follow books? Should I just dive into writing something and follow a reference manual as I go? What order should I do all this in? How should I do it? I want to completely master this; to be considered a genius. The most perfect career I can imagine is to start the next id. I have the drive to do it, I just don't know where to begin...

• How should I refactor switch statements like this (Switching on type) to be more OO?

  - by Taytay

  I'm seeing some code like this in our code base, and want to refactor it: (Typescript psuedocode follows): class EntityManager{ private findEntityForServerObject(entityType:string, serverObject:any):IEntity { var existingEntity:IEntity = null; switch(entityType) { case Types.UserSetting: existingEntity = this.getUserSettingByUserIdAndSettingName(serverObject.user_id, serverObject.setting_name); break; case Types.Bar: existingEntity = this.getBarByUserIdAndId(serverObject.user_id, serverObject.id); break; //Lots more case statements here... } return existingEntity; } } The downsides of switching on type are self-explanatory. Normally, when switching behavior based on type, I try to push the behavior into subclasses so that I can reduce this to a single method call, and let polymorphism take care of the rest. However, the following two things are giving me pause: 1) I don't want to couple the serverObject with the class that is storing all of these objects. It doesn't know where to look for entities of a certain type. And unfortunately, the identity of a type of ServerObject varies with the type of ServerObject. (So sometimes it's just an ID, other times it's a combination of an id and a uniquely identifying string, etc). And this behavior doesn't belong down there on those subclasses. It is the responsibility of the EntityManager and its delegates. 2) In this case, I can't modify the ServerObject classes since they're plain old data objects. It should be mentioned that I've got other instances of the above method that take a parameter like "IEntity" and proceed to do almost the same thing (but slightly modify the name of the methods they're calling to get the identity of the entity). So, we might have: case Types.Bar: existingEntity = this.getBarByUserIdAndId(entity.getUserId(), entity.getId()); break; So in that case, I can change the entity interface and subclasses, but this isn't behavior that belongs in that class. So, I think that points me to some sort of map. So eventually I will call: private findEntityForServerObject(entityType:string, serverObject:any):IEntity { return aMapOfSomeSort[entityType].findByServerObject(serverObject); } private findEntityForEntity(someEntity:IEntity):IEntity { return aMapOfSomeSort[someEntity.entityType].findByEntity(someEntity); } Which means I need to register some sort of strategy classes/functions at runtime with this map. And again, I darn well better remember to register one for each my my types, or I'll get a runtime exception. Is there a better way to refactor this? I feel like I'm missing something really obvious here.

• Is this a valid implementation of the repository pattern?

  - by user1578653

  I've been reading up about the repository pattern, with a view to implementing it in my own application. Almost all examples I've found on the internet use some kind of existing framework rather than showing how to implement it 'from scratch'. Here's my first thoughts of how I might implement it - I was wondering if anyone could advise me on whether this is correct? I have two tables, named CONTAINERS and BITS. Each CONTAINER can contain any number of BITs. I represent them as two classes: class Container{ private $bits; private $id; //...and a property for each column in the table... public function __construct(){ $this->bits = array(); } public function addBit($bit){ $this->bits[] = $bit; } //...getters and setters... } class Bit{ //some properties, methods etc... } Each class will have a property for each column in its respective table. I then have a couple of 'repositories' which handle things to do with saving/retrieving these objects from the database: //repository to control saving/retrieving Containers from the database class ContainerRepository{ //inject the bit repository for use later public function __construct($bitRepo){ $this->bitRepo = $bitRepo; } public function getById($id){ //talk directly to Oracle here to all column data into the object //get all the bits in the container $bits = $this->bitRepo->getByContainerId($id); foreach($bits as $bit){ $container->addBit($bit); } //return an instance of Container } public function persist($container){ //talk directly to Oracle here to save it to the database //if its ID is NULL, create a new container in database, otherwise update the existing one //use BitRepository to save each of the Bits inside the Container $bitRepo = $this->bitRepo; foreach($container->bits as $bit){ $bitRepo->persist($bit); } } } //repository to control saving/retrieving Bits from the database class BitRepository{ public function getById($id){} public function getByContainerId($containerId){} public function persist($bit){} } Therefore, the code I would use to get an instance of Container from the database would be: $bitRepo = new BitRepository(); $containerRepo = new ContainerRepository($bitRepo); $container = $containerRepo->getById($id); Or to create a new one and save to the database: $bitRepo = new BitRepository(); $containerRepo = new ContainerRepository($bitRepo); $container = new Container(); $container->setSomeProperty(1); $bit = new Bit(); $container->addBit($bit); $containerRepo->persist($container); Can someone advise me as to whether I have implemented this pattern correctly? Thanks!

• Trying to find resources to learn how to test software [closed]

  - by Davek804

  First off, yes this is a general question, and I'd be perfectly happy to move this to another portion of SE, but I didn't see a more fitting sub. Basically, I am hoping a more experienced QA tester can come along and really fill in some basics for me. So far, websites seem to be sparse in terms of explaining languages involved, basic practices, etc. So, I'm sorry in advance if this is too general, but towards the end of this post I ask some specific questions if it's just absolutely unacceptable to speak in general terms. I just landed a position as Junior Systems and QA Engineer with a social media startup. Their QA and testing is almost nonexistent, so if I do a good job, I imagine I'll find a lot of bugs and have a secure role in the business. I'm pretty good with the systems aspect of my role, but I need to learn more about the QA and testing aspects. We run hardware that's touchscreen based - the user can use and interact with the devices. So, in terms of my QA role, in the short term, I need to build scripts to test the hardware/software as a 'user' to try to uncover bugs. First off, what language should these scripts be written in? Does anyone have some examples? What about the longer term 'automated testing'? I'm familiar with regression testing as the developer adds in new features, sure, but the 50,000 other types of testing, not so much. Most of our hardware runs dotnet/C# code, with some of the servers running Java - but I don't expect to need to run tests on the Java side at this point. I hope to meet with one developer today and try to get a good idea of the output from the hardware so that I can 'mock' this data that gets sent to servers, to try to bugtest. Eventually, we will be moving the hardware to be closer to where I live and work, so that I can test virtually and on real hardware. So a lot of the bugs we're dealing with now are like this: the Local Server, which kiosks report their data to gets updated from the kiosks, but the remote server does not. Or, vis versa when the user registers on a kiosk, the remote server updates but the local server does not. But yeah, without much more detail, I imagine a lot of this info isn't helpful. I've bought a book "How Google Tests Software", but it's really a book more about 'how their software testing is different from Microsoft'. It doesn't teach how to test so much as why their methods are better. Does anyone have a good book that I can buy? An ebook maybe? My local Barnes and Noble kinda had a terrible selection. I also figure a book from 2005 is not necessarily that good either.

• NTUSER.DAT and UsrClass.dat files building up by the thousands, why and can I delete?

  - by Anthony

  I've noticed that my web server, 2008 Xen VM, gradually loosing free space - more than I would of though from normal use and decided to investigate. There are two problem areas: *C:\Users\Administrator\ (6,755.0 MB)* with files: NTUSER.DAT{randomness}.TMContainer'0000 randomness'.regtrans-ms NTUSER.DAT{randomness}.TM.blf AND C:\Users\Administrator\AppData\Local\Microsoft\Windows\ (6,743.8 MB) with files UsrClass.dat{randomness}.TMContainer'0000 randomness'.regtrans-ms UsrClass.dat{randomness}.TM.blf From what I understand these are in-time backups of registry changes. If that is the case I cannot possibly understand why there would be 10000+ changes. (That's how many files there are per folder location, over 20,000 per folder in total.) The files are using almost 15GB of space and I want rid of them, I'm just wondering can I remove them. However, I need to understand why they are being created so I can avoid this in the future. Any ideas why there would be so many? Is there a way I can check to see what is making the modifications? Are they created with login attempts? Are they created in relation to every day Web Server use? etc. and so on

• Ubuntu boot hangs after message "Running /scripts/init-bottom ... done"

  - by Douglas B. Staple

  I've been trying to copy a Proxmox container based on the Ubuntu Precise Standard template to a VirtualBox VM. I am now stuck at a point where my new Ubuntu/VirtualBox VM hangs after the message "Running /scripts/init-bottom ... done" during boot. I started by installing Ubuntu Server 12.04.4 LTS on a VirtualBox VM. Ubuntu Server 12.04.4 LTS was the closest "official" Ubuntu ISO to the Proxmox container OS I could find. I installed all updates on both the Proxmox container and on the VirtualBox VM. The idea was to get same version kernal running on the ProxMox container and VirtualBox VM. sudo apt-get update ; sudo apt-get upgrade ; sudo apt-get dist-upgrade sudo reboot rsync the entire proxmox container to a temporary directory in the VirtualBox VM: cd / mkdir /tmp/backup rsync -e ssh -av --exclude={/dev,/proc,/sys,/tmp,/run,/mnt,/media,/lost+found,/boot,/selinux} root@my_proxmox_container_hostname:/ /tmp/backup Shut down the virtual machine, and boot the VM with a bootable linux image. I used the Desktop image of Ubuntu 12.04 LTS, ubuntu-12.04.4-desktop-i386.iso Drop to a root prompt. Mount the VM root filesystem: sudo mount /dev/sda1 /mnt Remove files from most of /mnt cd /mnt sudo rm -rf bin etc home lib opt sbin root usr var Move all of the files from /mnt/backup into /mnt sudo mv /mnt/tmp/backup/* /mnt Rebooted system. For me, at this point the system freezes after starting, after the message: Running /scripts/init-bottom ... done I've tried reinstalling GRUB and all manner of other thing. I am almost ready to give up.

• Updating Windows DNS records from a remote windows DNS server

  - by Luckyboy

  Does anyone know if it is possible for a windows 2003 DNS server to update the records for a domain so that it contains all the records of a domain of of a remotely based DNS server? Im almost certain that doesn't quite explain the problem so I shall illustrate with an example: We have two offices, both are based about 100 miles apart. One deals with IT (Intranet development etc.) while the other is a call centre that uses the Intranet systems. Currently each office has its own DNS server, with the IT office's and call centre's DNS servers containing entries for intranet site. The difference is that the IT DNS server records point to the various servers that host the Intranet sites (e.g. intranetsite1 - 192.168.1.10, intranetsite2 - 192.168.1.11) while all of the entries in the call centre's DNS point to the IT office's DNS server (intranetsite1 - [it office ip address], intranetsite2 - [it office ip address]). Is there any way that the call centre's DNS server could automatically add all DNS records hosted by the IT office's DNS, translating the IP addresses to the IP address of the IT office?

• My SMTP's outgoing mail gets bounced

  - by BloodPhilia

  I've got a ISPconfig 3 production server set up, running Ubuntu Server 9.04. My e-mail gets delivered ok to almost every other server I send mail to except for one (smtp.chello.nl which bounces my email). In my /var/log/mail.err I found the below error.

• IPtables AWS EC2 NAT/Reverse NAT - For Reverse Proxy style setup but with IPtables

  - by Mark

  I was thinking initially needing to do a reverse proxy or something so I could get some SSL/TLS traffic look like it is being terminated at a server and IP address in the AWS cloud, and then that traffic is forwarded onto our actual web servers that aren't in the cloud... I've not done much iptables pre and post routing before Dnat or Snat which I know are the things I need or a combination of the things I need in order achieve what i'm trying. Things to note:- Client/User - Must not be able to see backend IP address and only see the IP address of the cloud box https (TLS/SSL) - connection shouldn't be terminated at the cloud box, it should act like a router almost EC2 instance - Has only one network interface available to play with... this is thus an (internet <- internet) type of routing going on. EC2 instance IP address is already more or less behind a NAT that I have no control over, for example... Public ip address could be 46.1.1.1 but instance IP will be 10.1.1.1. Connections from client will go to 46.1.1.1 which will end up at the instance and on interface 10.1.1.1. The connection from the client then needs to be forwarded (DNAT) onto the backend web servers which are back out on the internet (SNAT). Possibly a part of the problem could be that the SNAT will need to be set to the external interface of the instance and I wonder if this makes it harder for IPtables to track the connection? So looking to basically, have it look as though connections are terminating at this server and its IP address. Whereas all that's really happening is the https request and connection is being forwarded straight onto another internet facing web server. How possible does that sound?

• Moving from ColdFusion 8 to ColdFusion 10 - Migration Fails

  - by XenoFoxx

  After having made several attempts to migrate from a ColdFusion 8 Standard server to a ColdFusion 10 Standard server, it feels like I am "almost" there. I'm using the 64 bit installer from Adobe's website. I'm using a Windows Server 2008 (64 bit) server with IIS 7.0. The installation itself goes smooth and the services start and are running. But at the end of the installation it says "ColdFusion Installed, but with errors" and it generates a log file. The log file reads: Migration Error: : Check that "C:\ColdFusion8" is a valid directory and is an installation of either ColdFusion MX 6 or ColdFusionMX 7 and further down says: Status: WARNING Additional Notes: WARNING - Could not migrate settings from previous version of ColdFusion Custom Action: com.macromedia.ia.action.MigrateColdFusionAction Status: ERROR Additional Notes: ERROR - class com.macromedia.ia.action.MigrateColdFusionAction NonfatalInstallException null The applicationHost.config file has new XML referencing the ColdFusion 10 directory, but IIS is still using ColdFusion 8. I'm also going to guess that the settings in the CF Administrator have not been migrated based on the message in the log above. I've followed the instructions on Adobe's site, including ensuring that ASP.NET, CGI, ISAPI Extensions, and ISAPI Filters are all enabled. I've also enabled IIS 6 Metabase Compatibility even though I don't think it's needed. Has anyone else had similar issues with ColdFusion 10 and IIS 7. Currently I have uninstalled CF 10 and reverted back to

• Trying to run chrooted suPHP with UserDir, getting 500 server error

  - by Greg Antowski

  I've managed to get suPHP working fine with UserDir (i.e. PHP files run from the /home/$username/public_html) directory, but I can't get it to work when I chroot it to the user's home directory. I've been following this guide: http://compilefailure.blogspot.co.nz/2011/09/suphp-chroot-gotchas.html And adapting it to my needs. I'm not creating vhosts, I just want PHP scripts to be jailed to the user's home directory. I've gotten to the part where you use makejail and set up a symlink. However even with the symlink set up correctly, PHP scripts won't run. This is what's shown in the Apache error log: SoftException in Application.cpp:537: Could not execute script "/home/jimmy/public_html/test.php" [error] [client 127.0.0.1] Caused by SystemException in API_Linux.cpp:444: execve() for program "/usr/bin/php-cgi" failed: No such file or directory The thing is, if I try running either of the following commands in the terminal it works without any issues: /home/jimmy/usr/bin/php-cgi /home/jimmy/public_html/test.php /usr/bin/php-cgi /home/jimmy/public_html/test.php I've been trying for hours to get this going and documentation for this kind of stuff is almost non-existent. If anyone could help me out with this, I'd be extremely grateful.

• Windows 2008 Terminal Services "Easy Print" and Matrix Printers

  - by Cesar87

  Server: Windows 2008 Server Standard SP2 with "Terminal Services" role Clients: Windows XP SP3 + .NET 3.5 Framework SP1 + Remote Desktop Client 7.0 We are using "Easy Print" feature which allows programs running on server to "see" printers installed on client machines. Everything works fine, EXCEPT when we send a text-only output to a dot-matrix printer. In this case, the printer only outputs a blank page. At first, we had problems with the error "Windows Presentation Foundation Terminal Server Print W has encountered a problem and needs to close." but this was fixed by replacing TsWpfWrp.exe with the one from Vista SP1 as suggested here. But now, we only get a blank page! Every other (graphical) document we sent to printer works 100%. We also tried to use the "Generic text-only" driver, but the result is same. Now we are trying to change parameters like print processor on "advanced" tab from printer driver to see if something happen. But this is just guessing and we really don't know what to try anymore. The problem appears to be on Easy Print driver, but we found almost no resources about it. Any tips are welcome.

  Hello, everyone! I have an old Toshiba Satellite 4015CDT, with Pentium II MMX, 32MB RAM, 4GB HDD. It also has one USB 1.0 port, parallel and serial ports, a 3.5" floppy drive and a CD-ROM drive (probably almost dead). I've installed NetBSD on this machine (full install) and now I want to connect it to the Internet. Although it has one PCMCIA modem card in it, it is obviously not an option. I've narrowed down my available options to the following: Connect a USB wireless adapter. I have a Realtek RTL8192 adapter, but although the system gives me the device's name (through dmesg) it fails to recognize it as a network adapter. Connect the laptop to another machine through a serial connection, so that the other machine will serve as a bridge to the Internet. Here is the page from the NetBSD documentation on serial connections. Unfortunately, I was not able to find anything on bridging there. I would very much appreciate your suggestions on the topic. Thanks in advance.

• Firebird 2.1: gfix -online returns "database shutdown"

  - by darvids0n

  Hey all. Googling this one hasn't made a bit of difference, unfortunately, as most results specify the syntax for onlining a database after using gfix -shut -force 30 (or any other number of seconds) as gfix -online dbname, and I have run gfix -online dbname with and without login credentials for the DB in question. The message that I get is: database dbname shutdown Which is fine, except that I want to bring it online now. It's out of the question to close fbserver.exe (running on a Windows box, afaik it's Classic Server 2.1.1 but it may be Super) since we have other databases running off of that which need almost 24/7 uptime. The message from doing another gfix -shut -force or -attach or -tran is invalid shutdown mode for dbname which appears to match with the documentation of what happens if the database is already fully shut down. Ideas and input greatly appreciated, especially since at the moment time is a factor for me. Thanks! EDIT: The whole reason I shut down the DB is to clear out "active" transactions which were linked to a specific IP address, and that computer is my dev terminal (actually a virtual machine where I develop frontends for the database software) but I had no processes connecting to the database at the time. They looked like orphaned transactions to me, and they weren't in limbo afaik. Running a manual sweep didn't clear them out, deleting the rows from MON$STATEMENTS didn't work even though Firebird 2.1 supposedly supports cancelling queries that way. My last resort was to "restart" the database, hence the above issue.

• ActiveSync devices causing accounts to lockout

  - by Abdullah

  When a user changes his account password for whatever reason (read: expired), and the old password is stored in his mobile device connected through EAS. This will cause his account almost immediately - as it should according to the lockout policy defined in the AD. It was easy to figure out that part. The hard part is keeping it from happening. I looked everywhere. Nothing. Basically there are four parts to the puzzle: the EAS device, the TMG (ISA) server, the EAS protocol and finally the AD. None of them have a way to stop the EAS device from failing to authenticate. So I figured I'll have to come up with a clever workaround. And the only thing I could come up with is to create a group for all EAS users and exclude them from the lockout policy, which obviously defeats the whole purpose of the policy, or to educate the users to update their devices with the new passwords, which is impossible. The question: Can you think of any other way to prevent EAS from locking out the accounts? Environment: Mostly iOS devices all through EAS. TMG 2010. Exchange 2007. AD 2008 R2.

• certutil -ping fails with 30 seconds timeout - what to do?

  - by mark

  The certificate store on my Win7 box is constantly hanging. Observe: C:\1.cmd C:\certutil -? | findstr /i ping -ping -- Ping Active Directory Certificate Services Request interface -pingadmin -- Ping Active Directory Certificate Services Admin interface C:\set PROMPT=$P($t)$G C:\(13:04:28.57)certutil -ping CertUtil: -ping command FAILED: 0x80070002 (WIN32: 2) CertUtil: The system cannot find the file specified. C:\(13:04:58.68)certutil -pingadmin CertUtil: -pingadmin command FAILED: 0x80070002 (WIN32: 2) CertUtil: The system cannot find the file specified. C:\(13:05:28.79)set PROMPT=$P$G C:\ Explanations: The first command shows you that there are –ping and –pingadmin parameters to certutil Trying any ping parameter fails with 30 seconds timeout (the current time is seen in the prompt) This is a serious problem. It screws all the secure communication in my app. If anyone knows how this can be fixed - please share. Thanks. P.S. 1.cmd is simply a batch of these commands: certutil -? | findstr /i ping set PROMPT=$P($t)$G certutil -ping certutil -pingadmin set PROMPT=$P$G EDIT1 I have succeeded to pin down the single windows API that causes the problem - DsGetDcName According to the windbg, the certutil -ping invokes it like so: PDOMAIN_CONTROLLER_INFO pdci; DWORD ret = ::DsGetDcName(NULL, NULL, NULL, NULL, DS_DIRECTORY_SERVICE_PREFERRED, &pdci); On my workstation it times out for 30 seconds and then returns error code 1355, which is ERROR_NO_SUCH_DOMAIN No domain controller is available for the specified domain or the domain does not exist. On another machine, which is accidentally a windows server 2003, it returns almost immediately with the correct domain controller name inside the returned DOMAIN_CONTROLLER_INFO structure. Now the question is what is missing on my workstation for that API to find the correct domain controller?

• What exactly is a Mobile mouse? + Mouse Recommendation

  - by chobo2

  I am really disappointed with Logitech. My first cordless wireless mouse was from them and it lasted like 5 years. So I decided to get another one from them http://www.futureshop.ca/catalog/proddetail.asp?logon=&langid=EN&sku_id=0665000FS10099373&catid= And this mouse sucks bad. After 6 months it broke. I returned it under warranty and got a new one now 4-6 month later it is on the verge of breaking again.... You pay like $50 for this mouse and it lasts like 6 months that sad. I just lost faith in Logitech mice as I remember my bro also had a logitech mouse too and it broke after like 6 months. He then bought another logitech mouse(different model) that has been working for maybe 2 years(and no signs of breaking) but I am not crazy about the mouse(I don't like the 2 buttons by the wheel) and I not sure if they even sell it(maybe they got rid of it because it lasts too long). http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=1578495&CatId=1285 So I am looking at a Microsoft mouse. http://www.futureshop.ca/catalog/proddetail.asp?logon=&langid=EN&sku_id=0665000FS10125565&catid= I am looking at this one but I am not sure what they mean by mobile mouse. I think that is what MS calls notebook mice. So I am not sure if this would be a good mouse to get for a desktop. I see it uses like a micro usb receiver but I am not sure if it is smaller then a standard mouse. But almost all the mice I looked at at futureshop.ca or staples are labeled notebook mice or mobile mice. So not sure what mice would be right for me. I don't want a corded one though. I really liked the LX6 design alot but it can't last more than 6 months. Thanks

• How does Microsoft Word And Excel Run without any installation?

  - by Sathya

  I was having a discussion on bookmarks in Word with a friend, and he suggested me to check out his implementation of a query in Word. Since I did not have Microsoft Word installed, I told him I don't have Word so I won't be able to test it. To this, he mentioned that he'll send the executables and it will work - I argued that without an installation this will fail. I was rather shocked when he sent me the standalone executables and on running them, Word actually launched and I was able to use almost every functionality o_0 How's this possible? I've never installed Microsoft Office on my system, this isn't any "portable" app or VMWare ThinStall ( thanks nhinkle, didn't know about this). There are absolutely no Microsoft Office related files - except for winword.exe and excel.exe. Curiously even Microsoft Excel works fine with just the standalone executable. winword.exe size is about 38 MB, and excel.exe size is just 35kb, which makes it even more strange. I'm running on Windows XP, the files were from Office 2003. I was discussing this on Chat prior to posting, here's the conversation

• ADSIEdit Cleanup After Exchange 2003 Crash During Transition To Exchange 2010

  - by ThaKidd

  Hello all. I would value some input from a few Exchange 2010 experts. I have almost completed the transition from Exchange 2003 Standard to Exchange 2010 Standard. Everything went smoothly until I tried to uninstall Exchange 2003. At that point the server bit the dust and died completely. I now have NO access to the old Exchange System Management MMC as I am running Windows 2008 SR2 and Windows 7 only. I can only fix this with ADSIEdit, EMShell, and EMConsole. I have used the 2010 shell to move/remove/verify that all mailboxes, public folders and OAB are hosted on Exchange 2010. I also verified that the routing connector has been deleted. The only two things that were not done was to remove the Recipient Update Service and actually perform the removal of the 2003 software. I have spent a lot of time going through ASDIedit and have located the old Administrative Group and the Exchange 2003 server listed under it. I also located the Recipient Update Service which includes two entries; Enterprise and my domain name. I have read that it is an unwise idea to remove the old administrative group so I won't bother messing with that. I am repeatedly getting three warnings in the Application Log. Both are from MSExchangeTransport EventID 5006 (Cannot find route to Mailbox Server OLDSERVER) and 5020 (The topology doesn't contain a route to Exchange 2000 Server or Exchange Server 2003) So my questions are: To clean out AD of the old Exchange 2003 info, can I delete the server name folder (Configuration - Services - Microsoft Exchange - ExchOrg - Administrative Groups - First Administrative Group - Servers - Old Server) and also delete the Update Recipient Service (Enterprise) and Update Recipient Service (DOMAIN) containers safely? Are there any additional items I need to address to ensure the AD is clean? Thanks in advance for your help!

• Remote Desktop Mobile mangles barcodes coming from scanner

  - by sfonck

  We have an application here using handhelds to scan barcodes. These handhelds are actually making a remote desktop session towards a server where the application runs. Works fine. Now we have bought some new Motorola MC55's running 'Windows Mobile 6.1 Classic', and when using the application over remote desktop: it mangles the characters of the barcodes.... I already tried following things: When scanning a barcode on the MC55 itself it is displayed correctly When scanning a barcode via the remote desktop into a notepad session it is incorrect. Played with all options of the 'Remote Desktop Mobile' - no result Disabled 'autocorrect' and 'suggest words when entering text' on the input settings - no result The strange things is: a barcode which consists of only numbers gets scanned correctly the mangled characters comes through in lower case For some codes \t is mangled in between (should normally be entered after the barcode) e.g.: 'PERIN4' becomes 'ERINp4' 'MGZB' becomes 'GZB m' 'BAK664' becomes 'AK664 b' 'MAGBFA01' becomes 'AGBFmA01' '5021879949500' gets scanned correctly Final solution: Suppllier of the handhelds said the handheld was sending the characters too fast over the remote desktop connection. They changed the handheld to wait for 50ms between sending each character, which produced correct results right now. Scanning a barcode became somewhat slower but it's almost not remarkable to endusers.
