• How do I set zone priority in Microsoft DNS?

  - by Justin

  I have a standard small network setup (20 users) on Active Directory. All Windows machines have a primary DNS server as the AD and a secondary DNS server as Google PDNS. I want to setup a DNS entry that exists in real DNS but set it up on our DC so that local requests would route this public domain to a local development machine on the network. I setup the zone in DNS which results in the clients resolving the public FQDN to our internal IP. However, sometimes it still resolves to the "real" value (I check by pinging it). Is there some way to give the zone definition in my DC DNS higher priority? Or will the client that has secondary public DNS always at sometimes have a competing entry for this zone?

• How can I use an SSH tunnel for all traffic from a single application, without knowing the ports used?

  - by Matthew Read

  I have an application that opens connections on dozens of ports, and doesn't provide documentation about which ports it uses. I could use Wireshark or something to capture the traffic and export the ports from that, but I think it should be simpler than that. (And I'm not sure I would be able to cover all use cases and ensure the app used every single port it can ever use.) So I'm looking for a way to just say "forward all traffic from this application" (bonus points for all traffic from child processes as well) without needing to worry about specific ports. I'm sure there must be a way, but I couldn't hit on the right keywords while searching Google. How can I do this?

• What are the hard and fast rules for Cache Control?

  - by Metalshark

  Confession: sites I maintain have different rules for Cache Control mostly based on the default configuration of the server followed up with recommendations from the Page Speed & Y-Slow Firefox plug-ins and the Network Resources view in Google's Speed Tracer. Cache-Control is set to private/public depending on what they say to do, ETag's/Last-Modified headers are only tinkered with if Y-Slow suggests there is something wrong and Vary-Accept-Encoding seems necessary when manually gziping files for Amazon CloudFront. When reading through the material on the different options and what they do there seems to be conflicting information, rules for broken proxies and cargo cult configurations. Any of the official information provided by the analysis tools mentioned above is quite inaccessible as it deals with each topic individually instead of as a unified strategy (so there is no cross-referencing of techniques). For example, it seems to make no sense that the speed analysis tools rate a site with ETag's the same as a site without them if they are meant to help with caching. What are the hard and fast rules for a platform agnostic Cache Control strategy? EDIT: A link through Jeff Atwood's article explains Caching in superb depth. For the record though here are the hard and fast rules: If the file is Compressed using GZIP, etc - use "cache-control: private" as a proxy may return the compressed version to a client that does not support it (the browser cache will hold files marked this way though). Also remember to include a "Vary: Accept-Encoding" to say that it is compressible. Use Last-Modified in conjunction with ETag - belt and braces usage provides both validators, whilst ETag is based on file contents instead of modification time alone, using both covers all bases. NOTE: AOL's PageTest has a carte blanche approach against ETags for some reason. If you are using Apache on more than one server to host the same content then remove the implicitly declared inode from ETags by excluding it from the FileETag directive (i.e. "FileETag MTime Size") unless you are genuinely using the same live filesystem. Use "cache-control: public" wherever you can - this means that proxy servers (and the browser cache) will return your content even if the rest of the page needs HTTP authentication, etc.

• import macintosh thunderbird emails to windows email

  - by Ryan

  My mac laptop died. The hard drive is good. I am able to pull what I need off my mac and copy it to windows using an open source tool (I forgot the name of it). I need my old mac emails. I was using the macintosh thunderbird for emails. How do I load those emails into thunderbird, outlook, or any other windows email tool? I did google this and there were some brief explanations, but they did not work. The vast majority of posts are about going from windows to mac.

• Need Boxee/Vista remote control recommendations

  - by gurun8

  I have an Acer Aspire X1200 (specs link below) desktop computer that I've installed Boxee on and it works great. And it looks like it's going to be a perfect computer for a media player. It's small with lots of hard drive space and even has a HDMI output on it. http://support.acer.com/acerpanam/desktop/0000/Acer/AspireX1200/AspireX1200sp2.shtml I also have a Harmony® 880 Advanced Universal Remote (specs link below) that I'd like to use with the Acer computer. www.logitech.com/en-us/440/372 My thought is that I need to get a USB remote control adapter, right? So I did a quick Google search and found products from $5 to hundreds of $$$. Does anyone have recommendations? Things you like/dislike about certain remotes? This Acer is running Vista and has a AMD LIVE!: Athlon X2 dual-core processor. 64 bit some times makes it a little more difficult. Thanks for the help.

• Attempting to caue packet loss with netem doesn't work - possibly because of NAT (but delay does work)

  - by tomdee

  I have traffic from a WIFI access point routed via an Ubuntu box. I have two network interfaces which are NATed *filter :INPUT ACCEPT [11:690] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [37:6224] -A FORWARD -s 192.168.2.0/24 -i eth1 -o eth0 -m conntrack --ctstate NEW -j ACCEPT -A FORWARD -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT COMMIT # Completed on Thu Mar 15 13:37:21 2012 # Generated by iptables-save v1.4.10 on Thu Mar 15 13:37:21 2012 *nat :PREROUTING ACCEPT [0:0] :INPUT ACCEPT [0:0] :OUTPUT ACCEPT [0:0] :POSTROUTING ACCEPT [0:0] -A POSTROUTING -j MASQUERADE COMMIT If I run a ping app on an Android device connected to the WIFI network I can happily ping google. If I use netem to introduce some delay tc qdisc change dev eth0 root netem delay 100ms I can clearly see pings taking longer. If I use netem to introduce some packet loss tc qdisc change dev ifb0 root netem loss 50% then I see no change. Packet loss does work fine for locally generated traffic, just not for traffic coming in over the network that's being NATed. Any ideas how to sort this out?

• Cannot open any web page, but MSN Messenger works

  - by Steven

  I use my computer behind a router. My MSN program can connect to the Internet, but I can not open any web site with my web browser. It seems that this problem is related to DNS because when I input an IP address directly in the address bar of my web browser, the web page can be displayed. However, I don't know how to fix this problem. I choose Google Public DNS server on my computer, this problem still exists. My OS is windows XP. How to fix this problem? Any ideas?

• SEO: Make hashtag links look static

  - by elias94xx

  So I have a website which displays all my content vertically. (like modern websites often do these days). Thus I can't create static links to each section. I'm currently handling the scrolling with javascript. My navigation looks like this. <ul> <li><a href="#services">Services</a></li> <li><a href="#references">References</a></li> <li><a href="#blog">Blog</a></li> <li><a href="#contact">Contact</a></li> </ul> I also created 301 redirect links with htaccess. E.g. /services which leads to /#services. If I were to use them in my navigation, I'd have to trigger the scrolling with the onpopstate event. Thats not really a problem, but would searchengines accept that kind of setup ? I also created a sitemap and submitted it to google, but the indexing is still pending.

• Barring connections if VPN is down.

  - by Majid

  I have a VPN account and use it for sensitive communication. However the VPN connection sometimes is dropped while my main connection to the internet is still alive. The pages I visit through VPN are on HTTP (not secure) and have javascript code which pings the host every minute or so on a timer. So it happens sometimes that the VPN connection is dropped and yet js sends a request to the server (with the cookies). How could I restrict connections so they only happen if the VPN is live? Edit - Some required details were missing OS: Windows XP SP2 Browser (mostly used): Google Chrome Firewall: Windows default Sites to filter: not all traffic but all in a list of sites like abc.com, xyz.com

• How to calculate Bradford Factors with Excel 2007?

  - by pnuts

  Bradford Factors are used by some to measure the significance of absenteeism and are computed for each individual as S squared * D where S is the number of spells (continuous periods of absence) and D is the sum of the days. The calculation is often made over a rolling 52 weeks. Commercial HR software often has the facility to calculate these factors but a Google search indicates quite a lot of interest without any free solutions. Using units of half a day and including any non-working days in each spell, how does one calculate the factors using Excel 2007?

• How to query a DHCP server to get the local DNS servers

  - by Dan Berlyoung

  I have a ClarkConnect (CentOS based) box running as my home router on a RR connection. I had the DNS servers set up to use Google's DNS server. I want to change them back to the local DNS servers but I can't find an obvious/easy way to get those address short of a) reconfiguring the router's network to DHCP them (would rather not interrupt everyone) or b) calling their tech support (kill me now!). Is there a command line tool/command I can use to query the DHCP server on the external NIC to see what DNS servers it would set me up with w/o munging my existing setup?

• emacs and putty on windows 7

  - by twilbrand

  My workstation was recently updated to Windows 7. I've downloaded putty and have configured it to the same settings I had under Vista. Whenever I ssh to a vm running Centos 5.4 and try to run emacs on a file, I'm getting an error about a connection to an X server: [ecto1 ~]$ emacs foo.bar Connection lost to X server `localhost:10.0' I never received this error message when I had Vista. I can get around it by aliasing emacs to 'emacs -nw', but I don't feel that I should have to do this. My co-worker has the same hardware that had the same upgrade and his sessions do not seem to be doing this. Any advice? I can't find anything on google and don't know where else to start. [ecto1 ~]$ emacs -version GNU Emacs 21.4.1

• Problem connecting to MySQL with zend

  - by wheresrhys

  I've set up a virtual host on my local machine (windows xp with xampp installed), have installed zend there and am now trying to connect to the MySQLdatabase. I get the following error message: Message: SQLSTATE[HY000] [2003] Can't connect to MySQL server on ''myhost.com'' (10060) All the tips I've found via google haven't helped. I use kaspersky antivirus and have added port 3306 to the allowed list for MySQL and Apache. I've also pinged myhost.com:3306 and get a response (with ip address 67.63.50.51), though localhost:3306 and 127.0.0.1:3306 aren't found. I've checked that other apps can still access MySQL if the virtual host is pointed at them instead and my non zend apps do work. I guess I have to do something further to the port, or maybe force the app to use a different port, but am not sure how to do either. Any help appreciated.

• Learning good OOP design & unlearning some bad habits

  - by Nick

  I have been mostly a C programmer so far in my career with knowledge of C++. I rely on C++ mostly for the convenience STL provides and I hardly ever focus on good design practices. As I have started to look for a new job position, this bad habit of mine has come back to haunt me. During the interviews, I have been asked to design a problem (like chess, or some other scenario) using OOP and I doing really badly at that (I came to know this through feedback from one interview). I tried to google stuff and came up with so many opinions and related books that I don't know where to begin. I need a good through introduction to OOP design with which I can learn practical design, not just theory. Can you point me to any book which meets my requirements ? I prefer C++, but any other language is fine as long as I can pick-up good practices. Also, I know that books can only go so far. I would also appreciate any good practice project ideas that helped you learn and improve your OOP concepts. Thanks.

• How can I disable logging in Tomcat 7?

  - by WilliamMayor

  I have a Tomcat 7 server running in a VM that has very little disk space (20G). Over the course of a few days Tomcat will fill the space with logging info (usually about 15G before it runs out). I've tried turning down the log level (from INFO to SEVERE) in the logging.properties file, I've also tried sending the log info to /dev/null. It doesn't seem to work as I still get a full log directory after no time at all. Can I put a file size limit on the log files? Is something overriding the properties I'm setting? Where can I find this information? My Google Fu just returns information about logging from within an application using JULI.

• Unable to delete Gmail profile in Outlook 2010

  - by Michele

  I used to have 2 Gmail profiles set up in Outlook 2010. I initially had it set up using IMAP, but I deleted it (or so I thought), and re-set it up the old-fashioned way without IMAP. Then finally, I deleted the 2nd Gmail profile altogether. So now I only have ONE Gmail profile set up in Outlook 2010 and it works fine. The problem is that the original Gmail IMAP folder for the 2nd Gmail account is still in my list of folders when I use Outlook. I've already disabled IMAP via my Google Gmail account. But I am unable to delete the folder from Outlook 2010. I have checked in the account settings and it is NOT in my list of email profiles or the data files. Has anyone else had this problem?

• How can I ensure my Collada model fits on an iPhone screen?

  - by rakeshNS

  Hi I am new to game development. I see many examples and tried myself like displaying triangle, cube etc. Now I am looking to render a Collada object. So I created a Collada object using Google Sketch up and trying to render that now. But the thing I am not understanding is, in all examples the vertices are between -1.0 and +1.0 values. But when I looked into that Collada file, the vertices were ranging from -30.0 to 90.0. I know any vertices greater than 1.0 will not display on iPhone. So can you pleas tell my the secret behind converting Object coordinate to normalized vector coordinate? My previous triangle defined as struct Vertex{ float Position[3]; float Color[4]; }; const Vertex Vertices[] = { {{-0.5, -0.866}, {1, 1, 0.5f, 1}}, {{0.5, -0.866}, {1, 1, 0.5, 1}}, {{0, 1}, {1, 1, 0.5, 1}}, {{-0.5, -0.866}, {0.5f, 0.5f, 0.5f}}, {{0.5, -0.866}, {0.5f, 0.5f, 0.5f}}, {{0, -0.4f}, {0.5f, 0.5f, 0.5f}}, }; And now triangle from collada is const Vertex Vertices[] = { {{39.4202092, 90.1263924, 0.0000000}, {1, 1, 0.5f, 1}}, {{-20.2205588, 90.1263924, 0.0000000}, {1, 1, 0.5, 1}}, {{-20.2205588, 176.3763924, 0.0000000}, {1, 1, 0.5, 1}}, {{-20.2205588, 176.3763924, 0.0000000}, {1, 1, 0.5, 1}}, {{-20.2205588, 90.1263924, 0.0000000}, {1, 1, 0.5, 1}}, {{39.4202092, 90.1263924, 0.0000000}, {1, 1, 0.5, 1}}, };

• Learning Programming from scratch

  - by David542

  I am entirely new to programming, other than basic HTML/CSS knowledge. I want to learn programming as quickly and efficiently as possible, and I'm willing to put in the time (at least 70 hours a week). The reason I want to learn is because I have a startup that I've written a business plan for and have prototyped in Photoshop (both front-end and back-end pages). My goals is to have a prototype of the site up within 6 months. I have a good aptitude for math (A's in all math courses up through DiffEq and Linear Algebra). I assume learning programming from scratch can be a daunting task -- not because it is particularly difficult, but because there are so many areas and so much information. I want to make sure that I learn as efficiently as possible and have individuals (in addition to Google) to solicit advice from and that will help me when I get stuck or have questions. I know with other's help, my learning experience will be both more productive and enjoyable. What is the best way to find people that will help me in this? What are some good 'live' resources in addition to asking questions on Stack Overflow? Thank you very much for your time and help.

• Converting PDF eBooks into a Kindle format

  - by Ender

  Over the past couple of years I've amassed quite a collection of guides, tutorials and ebooks in PDF format. A lot of these are quite useful for work, especially PDF documentation, and rather than have to be at a computer every time I want to read how to do something in Sitecore or to read through a software testing ebook I'd like to do it on my brand-spanking-new Kindle. However, even though there is now a native PDF reader on the Kindle due to the nature of PDF's they are practically unreadable. The text doesn't wrap due to how PDF's are sized and so far after a bunch of Google searches I've yet to find a viable solution to get my PDF's converted into a readable Kindle format. Sometimes these books have code or pictures/tables in them, but most of the time they're text-heavy and to be honest I'd be surprised if there wasn't a free tool to handle the converting of PDF to one of the (seemingly many) Kindle formats. So, can anyone help me out with this?

• How to pass AppleScripts display dialog to Growl or growlnotify?

  - by pattulus

  I have this simple AppleScript which takes the text in the clipboard and outputs the amount of words and characters used. What I'm trying to do is passing "display dialog" to Growl or growlnotify. I know how to use growlnotify in the shell - it's great and highly customizable (stick note, assign app icon or an image, etc) - but the point is: I don't know how to do it in AppleScript. I google a bit but now time has passed and I decided to post my question here. So, here's the script: set myCount to count (the clipboard) set myWords to count words of (the clipboard) set myParas to count paragraphs of (the clipboard) display dialog "Characters: " & myCount & " Words: " & myWords & " Paragraphs: " & myParas Thanks.

• Does Firefox Phishing Protection / Safebrowsing have any privacy implications?

  - by Nowo

  The current google results are outdated. What is the current status? I was on www.mozilla.org/en-US/legal/privacy/firefox.html and saw "Protection Against Suspected Forgery and Attack Sites Features". Can you translate please more to human speak? First they download a list and compare local... Ok... Here it gets messy "If there is a match, Firefox will check with its third party provider to ensure that the website is still on the blacklist. The information sent between Firefox and its third party provider(s) are hashed URLs. In fact, multiple hashed URLs are sent with the real hash so that the third party provider(s) will not know what site you are visiting." - If that hash were send to mozilla, they would knew which site were accessed? "In order to safeguard your privacy, Firefox will not transmit the complete URL of web pages that you visit to anyone other than Mozilla and its service providers." - In other words, Mozilla and its service providers get all complete URLs (of sites, which were in blacklist)? "While it is possible that a third party service provider may determine the actual URL from the hashed URL sent, Mozilla’s policy is to require [...]" - Privacy is depends on policy rather than technology?

• Is there a framework for describing object oriented communication standards/protocols?

  - by martin

  Currently I'm dealing with the development of specifications for communication standards/protocols for b2b-integration based on object oriented models. I.e. if you take a look at the healthcare domain there is HL7v3 with its HDF. Now I ask if there is a more generic framework, that describes how a specification for a communication standard should be developed. For b2b-integration I want to describe a communication standard based on uml models for a broad domain. My thought was to divide the domain into subdomains and derive message type from the resulting model. There is already a given framework, but I want to compare it to another framework. My idea is to compare them using a generic framework. It should describe several levels. Does anybody know such a framework? I have searched a while on google scholar, but haven't an appropiate framework yet. The only thing I have found is ebXML, but I think it is not exactly what I need.
