• Project manager programming background

  - by Henryk Konsek

  Do you think that project manager should have programming background? Do you consider this role as a natural way of evolution for the skilled/leader programmers (as an alternative for architect role)? Or maybe you believe that PM should be just a good manager with a basic understanding of the programming concepts and a fundamental knowledge about the technology you use. What is your experience with working with both kinds of managers (ex-programmers or just managers).

• More RAM vs. more servers [closed]

  - by user357972

  I was recently asked "Do you know when to decide between going for more RAM or more servers?" (in the context of scaling data mining applications). I had no idea, so what are some ways to decide? I have very little knowledge of architecture and scaling (my understanding of computer memory and what a server does is limited to the high-level basics), so tips on learning more about these things in general are also very welcome.

• How To Prevent Processes From Starting?

  - by Rob P.

  I'm toying around with a very simplistic sort of process-monitor. Currently, it gets a list of the running processes and attempts to kill any process that is not white-listed. What I'm looking for is a way to prevent a process from starting that isn't on the white-list. If that's possible. My knowledge level in this area is pretty non-existent and my Google-fu only returns websites discussing Process.Start() :( Can anyone point me in the right direction?

• How is <tgmath.h> implemented?

  - by sync

  C doesn't have (to the best of my knowledge) overloading or templates, right? So how can a set of type-agnostic functions with the same name exist in plain ol' C? The usual compile-time trickery would involve a whole bunch of macros, wouldn't it?

• Is there a shorthand term for O(n log n)?

  - by jemfinch

  We usually have a single-word shorthand for most complexities we encounter in algorithmic analysis: O(1) == "constant" O(log n) == "logarithmic" O(n) == "linear" O(n^2) == "quadratic" O(n^3) == "cubic" O(2^n) == "exponential" We encounter algorithms with O(n log n) complexity with some regularity (think of all the algorithms dominated by sort complexity) but as far as I know, there's no single word we can use in English to refer to that complexity. Is this a gap in my knowledge, or a real gap in our English discourse on computational complexity?

• 'rsync' is not recognized as an internal or external command, operable program or batch file

  - by user1688269

  I am VERY new to rsync and cygwin and I'm pretty sure I've installed everything correctly. I am trying to (for now) just rsync two Windows XP Laptops to tranfer files across from the one to the other to get a feel of it before I tackle bigger projects. This is the code I try use to transfer the files but I always get the same error. $ rsync -zrptL -v -e 'ssh -p 222' /tmp/rawr/ [email protected]:/tmp/play [email protected]'s password: 'rsync' is not recognized as an internal or external command, operable program or batch file. rsync: connection unexpectedly closed (0 bytes received so far) [sender] rsync error: error in rsync protocol data stream (code 12) at /home/lapo/package/rsync-3.0.9-1/src/rsync-3.0.9/io.c(605) [sender=3.0.9] What could be the problem? I am really stuck at the moment.

• Cannot enable network discovery on Windows Server 2008 R2

  - by dariom

  I'm trying to enable the Network Discovery feature on a newly installed Windows Server 2008 R2 instance. The network connection is in the Home or Work profile (it is not domain joined). These are the steps I've followed: Within the Network and Sharing Center I select Change advanced sharing settings Then I select the Turn on network discovery option for the current network profile (Home or Work) I then click Save changes If I then go back to the Advanced sharing settings screen the Turn off network discovery option is selected and the machine is not visible to others within the Network node in Windows Explorer. Things I've checked: I can ping the server and connect to it using the machine name/IP address. The Windows Firewall has exceptions for Network Discovery for both Private and Public networks. File and Printer sharing is enabled and I can transfer files to/from the server by connecting to the server using a UNC path. What am I missing here?

• SFTP - Unable to Overwrite File - "EOF received from remote side"

  - by NateReid

  I am working with a customer to troubleshoot an error they have when trying to overwrite/"PUT" a file to our SFTP site. When the root directory is empty and they try to upload the file there is no problem but when they try to overwrite an existing file this is when the error occurs. The error they receive when trying a put command in Java Caps is: The error is: Batch SFTP eWay error when doing data transfer operation in [PUT()], message=[EOF received from remote side [Unknown cause]].|#] When they use WinSCP or FileZilla to put the file it overwrites fine with no errors. We have tried: Multiple different files Checking their SFTP user permissions Gave full access permissions to "everyone" to the user's root directory in Windows Recreating their user account Ensured no other processes are using/locking the files that are being overwriten We are using Cerberus Professional FTP server software. Any ideas of what else we could try?

• Run CGI in IIS 7 to work with GET without Requiring POST Request

  - by Mohamed Meligy

  I'm trying to migrate an old CGI application from an existing Windows 2003 server (IIS 6.0) where it works just fine to a new Windows 2008 server with IIS 7.0 where we're getting the following problem: After setting up the module handler and everything, I find that I can only access the CGI application (rdbweb.exe) file if I'm calling it via POST request (form submit from another page). If I just try to type in the URL of the file (issuing a GET request) I get the following error: HTTP Error 502.2 - Bad Gateway The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are "Exception EInOutError in module rdbweb.exe at 00039B44. I/O error 6. ". This is a very old application for one of our clients. When we tried to call the vendor they said we need to pay ~ $3000 annual support fee in order to start the talk about it. Of course I'm trying to avoid that! Note that: If we create a normal HTML form that submits to "rdbweb.exe", we get the CGI working normally. We can't use this as workaround though because some pages in the application link to "rdbweb.exe" with normal link not form submit. If we run "rdbweb.exe". from a Console (Command Prompt) Window not IIS, we get the normal HTML we'd typically expect, no problem. We have tried the following: Ensuring the CGI module mapped to "rdbweb.exe".in IIS has all permissions (read, write, execute) enabled and also all verbs are allowed not just specific ones, also tried allowing GET, POST explicitely. Ensuring the application bool has "enable 32 bit applications" set to true. Ensuring the website runs with an account that has full permissions on the "rdbweb.exe".file and whole website (although we know it "read", "execute" should be enough). Ensuring the machine wide IIS setting for "ISAPI and CGI Restrictions" has the full path to "rdbweb.exe".allowed. Making sure we have the latest Windows Updates (for IIS6 we found knowledge base articles stating bugs that require hot fixes for IIS6, but nothing similar was found for IIS7). Changing the module from CGI to Fast CGI, not working also Now the only remaining possibility we have instigated is the following Microsoft Knowledge Base article:http://support.microsoft.com/kb/145661 - Which is about: CGI Error: The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are: the article suggests the following solution: Modify the source code for the CGI application header output. The following is an example of a correct header: print "HTTP/1.0 200 OK\n"; print "Content-Type: text/html\n\n\n"; Unfortunately we do not have the source to try this out, and I'm not sure anyway whether this is the issue we're having. Can you help me with this problem? Is there a way to make the application work without requiring POST request? Note that on the old IIS6 server the application is working just fine, and I could not find any special IIS configuration that I may want to try its equivalent on IIS7.

  I am upgrading a Windows XP (32-bit) machine and a Windows Vista (32-bit) machine to Windows 7 (32-bit). The most important files and accounts are on the Windows XP machine. What I would like to do is the following: backup the XP machine using Windows Easy Transfer upgrade the Windows Vista machine to a fresh install of Windows 7 install the XP backup on the Vista machine and see if everything is working Is this possible? I would have thought its possible as once the Vista machine is upgraded to Windows 7 it should be the same as if I had upgraded the XP machine, but I don't want to waste my time if its not. Thanks

• How to migrate from Natara DayNotez for Pocket PC / Windows Mobile

  - by piggymouse

  I've been using DayNotez as my notes manager since the old Palm PDA days. When I moved to Windows Mobile, I installed DayNotez there and migrated from the Palm version. Now I wish to move from DayNotez altogether (I currently consider Evernote as a decent cross-platform tool). Problem is, DayNotez doesn't let me export the notes (unless I want to transfer them one by one, which is a pain). Natara offers an export tool for Windows, but it only works for Palm HotSync (as it reads from the backed-up PDB file). DayNotez Desktop for Windows stores its local DB under "My Documents\Natara\DayNotez\" directory in a file named "[device name] DayNotez.dnz". Quick look within the file spots a string "Standard Jet DB" near the beginning, but I couldn't open it as a regular JET/MDB file. Any help would be greatly appreciated.

• Packet loss rate with iperf and tcpdump

  - by stefita

  I tested a line for its link quality with iperf. The measured speed (UDP port 9005) was 96Mbps, which is fine, because both servers are connected with 100Mbps to the internet. On the other hand the datagram loss rate was shown to be 3.3-3.7%, which I found a little too much. Using a high-speed transfer protocol I recorded the packets on both sides with tcpdump. Than I calculated the packet loss - average 0.25%. Have anyone an explanation, where this big difference may be coming from? What is an acceptable packet loss in your opinion?

• Join Production Server 2008 to 2003 domain

  - by Campo

  I administer a production server for a .com. It is live right now. Server 2008 x64 IIS 7 SQL 2008 PHP MYSQL I have another server which is a DC Server 2003 x86 and a warm standby for the website, sql, DFS, exchange queue. In order to get DFS going to transfer user photos and other content I need it in the domain. My question is, What preparations do I need to do to the production server to allow a smooth transition onto the domain? Things such as permissions for the website. I do not want to be running around resetting all the permissions. The Group Policy on the DC is completely default. Should I add the DNS manually or allow it to add itself? Anything else I left out.

• Are spurious TCP connections on port 53 a problem?

  - by Darren Greaves

  I run a server which amongst other things uses tinydns for DNS and axfrdns for handling transfer requests from our secondary DNS (another system). I understand that tinydns uses port 53 on UDP and axfrdns uses port 53 on TCP. I've configured axfrdns to only allow connections from my agreed secondary host. I run logcheck to monitor my logs and every day I see spurious connections on port 53 (TCP) from seemingly random hosts. They usually turn out to be from ADSL connections. My question is; are these innocent requests or a security risk? I am happy to block repeat offenders using iptables but don't want to block innocent users of one of the websites I host. Thanks, Darren.

• Why PC reboots when there’s a power failure even with UPS?

  - by Jamil

  I've purchased a Line Interactive UPS 1200VA. It's supposed to give 8~20min backup (as written in the manual). This UPS has transfer time < 10ms. It works fine when the mains is active. But the problem is that when the power went off, the PC also went off for a fraction of a second and started rebooting. The strangest thing though is that it has to be a proper power failure by the service supplier. If I just turn off the power at the wall plug, the UPS kicks in immediately and the PC carries on working fine. What's the solution of that? What should I do? My hard drive was physically damaged because of improper shut down & restart. I've 5~8 times power outage in my country so I badly need an UPS.

• Corporate Wiki Organization - Technical Documentation

  - by Dave Jarvis

  Corporations have documents describing various aspects of their technical systems, including: Custom Applications Custom Development Frameworks Third Party Applications Accounting Bug Tracking Network Management How To Guides User Manuals Web Browsers Software Tools Development IDEs Graphics GIMP xv Text Editing File Transfer ncFTP WinSCP Hardware Servers Web Database Exchange File Network Devices Printers Drawings If you had to use a Wiki to manage the documentation, what other items would you add to the list, and how would you organize it? (For example, would Software Tools make more sense under Third Party Applications?) A few constraints: The structure should not go beyond three levels deep. Avoid the word "and" in favour of two different categories. Keep the structure general: it should appy as broadly as possible. Target audience is primarily technical, but could be visible by anyone.
