• "Countersigning" a CA with openssl

  - by Tom O'Connor

  I'm pretty used to creating the PKI used for x509 authentication for whatever reason, SSL Client Verification being the main reason for doing it. I've just started to dabble with OpenVPN (Which I suppose is doing the same things as Apache would do with the Certificate Authority (CA) certificate) We've got a whole bunch of subdomains, and applicances which currently all present their own self-signed certificates. We're tired of having to accept exceptions in Chrome, and we think it must look pretty rough for our clients having our address bar come up red. For that, I'm comfortable to buy a SSL Wildcard CN=*.mycompany.com. That's no problem. What I don't seem to be able to find out is: Can we have our Internal CA root signed as a child of our wildcard certificate, so that installing that cert into guest devices/browsers/whatever doesn't present anything about an untrusted root? Also, on a bit of a side point, why does the addition of a wildcard double the cost of certificate purchase?

• Private VOIP network

  - by SuppositoryPlacebo

  I own a small private security services business. Some of my clients require 2-10 security officers per location. I'm trying to think outside the box in order to solve my communications problem. I'd rather not buy or lease hf radios or voip systems at the current rates. I'm wondering if there is an existing system, or if is at all possible, to setup a private communications network using only a server and bluetooth devices or a wifi/bluethooth combination. http://25.media.tumblr.com/tumblr_m44f0pn7BL1rwp6tgo1_1280.png I don't need "radio" per se. I just need a simple, private voip network. Is there an existing device that consists of nothing more than a wifi adapter to control a bluetooth device?

• IIS and PHP restrict IO permissions

  - by ULTRA_POROV

  I have php installed trough a fastCGI module. Is there a way to restrict the module (php.exe) read / write permissions to only the directory (+ subdirs) of the IIS site that is calling it? I need this to prevent one IIS PHP site from having access to files outside its own directory. How to do this? Is there a setting in php.ini or in the IIS configuration? I believe such a feature could exist, because when a file on the server is requested the root path of the site is also known, all it would take is that IIS passes this path to the php module, and the php module should on its end allow only IO operations within this path. PS: I know it is possible to achieve this by using a different windows account for each website, this is not an option.

• Should I expect my peers to read or practice on a regular basis? [closed]

  - by Joshua Smith

  I've been debating asking this question for some time. Based several of the comments I read in this question I decided I had to ask. This feels like I'm stating the obvious, but I believe that regular reading (of books, blogs, StackOverflow, whatever) and/or practice are required just to stay current (let alone excel) in whichever stack you use to pay the bills, not to mention playing with things outside your comfort zone to learn new ways of doing things. Yet, I virtually never see this from many of my peers. Even when I go out of my way to point out useful (and almost always free) learning material, I quite often get a sense of total apathy from those I'm speaking to. I'd even go so far as to say that if someone doesn't try to improve (or at least stay current), they'll atrophy as technology advances and actually become less useful to the company. I don't expect people to spend hours a day studying or practicing. I have two young kids and hours of practice simply aren't feasible. Still, I find some time; perhaps on the train, at lunch, in bed for a few minutes, whatever. I'm willing to believe this is arrogance or naivete on my part, but I'd like to hear what the community has to say. So here's my question: Should I expect (and encourage) the same from my peers, or just keep my mouth shut and do my own thing?

• What is the standard technique for shifting the frames of a sprite according to user input?

  - by virtual__

  From my own experience, I developed two techniques for changing the sprites of a character that's reacting to user input -- this in the context of a classic 2D platformer. The first one is to store all character's pixmaps in a list, putting the index of the currently used pixmap in an ordinary variable. This way, every time the player presses a key -- say the right arrow for moving the character forward -- the graphics engine sees what's the next pixmap to draw, draws it, and increments the index counter. That's a pretty common approach I believe, the problem is that in this case the animation's quality depends not only on the number of sprites available but also on how often your engine listens to user input. The second technique is to actually play an animation every key press event. For this you can use any sort of animation framework you want. It's only necessary to set the timer, the animation steps and to call the animation's play() method on your key press event handler. The problem with that approach is that is lacks responsiveness, since the character won't react to any input while the current animation is still being played. What I want to know is whether you are using one of these techniques -- or something similar -- in your games, or whether there's a standard method for animating sprites out there that's widely known by everybody but me.

• How to import Exchange calendars in Google Calendar (No Desktop Outlook)

  - by Tonny Madsen

  I would like to import my calendar from my company Exchange 2010 server as a new calendar in my private Google account. The primary use is to easy my planning when at home with my laptop. I already have access to both the Google and Exchange calendars on my Android phone, but the size of the screen makes it rather difficult to plan anything serious. Note that I run OSX on my laptop I would prefer a Internet based solution to any software on my own laptop. I do not want an Outlook add-in I do not want to include the work related events in my main calendar I do not want a mobile solution I can pay for the solution

• Location-Based redirection and duplication in sub-directories affecting SEO

  - by Joshua

  I currently own the website www.xyz.com. The website has a sub-directory for each of the 3 target countries: .../en-US/ (United States), .../es-MX/ (Mexico), and .../es-DO/ (Dominican Republic). I have two main questions about this setup: Currently, the main domain/root (xyz.com) contains a blank index.php file, but I would like for a user to be redirected to one of the sub-directories based on their regional location. What is the best way to accomplish this? I have looked at using browser language-based redirection, but how would I know whether to direct a user to the MX or DO site if the browser language is set to spanish? Is there a way to detect a user's geographic location? Also, the 3 websites are practically identical except they all have 3 unique color schemes and the US site is in english while the MX and DO sites are in spanish. My problem is that I believe GoogleBot is penalizing/banning my site because the spanish text on the MX and DO pages are nearly identical and are thus marked as duplicates/spam. Is there a way to avoid this?

• github team workflow - to fork or not?

  - by aporat

  We're a small team of web developers currently using subversion but soon we're making a switch to github. I'm looking at different types of github workflows, and we're not sure if the whole forking concept in github for each developer is such a good idea for us. If we use forks, I understand each developer will have his own private remote & local repositories. I'm worried it will make pushing changesets hard and too complex. Also, my biggest concern is that it will force each developer to have 2 remotes: origin (which is the remote fork) and an upstream (which is used to "sync" changes from the main repository). Not sure if it's such a easy way to do things. This is similar to the workflow explained here: https://github.com/usm-data-analysis/usm-data-analysis.github.com/wiki/Git-workflow If we don't use forks, we can probably get by fine by using a central repo creating a branch for each task we're working on, and merge them into the development branch on the same repository. It means we won't be able to restrict merging of branches and might be a little messy to have many branches on the central repository. Any suggestions from teams who tried both workflow?

• Directory "Bookmarking" in Linux

  - by Jason R. Mick

  Aside from aliasing and links, is there an easy way in Linux to tag commonly used directories and to navigate to a commonly used directory from the terminal. To be clear the disadvantages I see with alternative approaches, and why I want a bookmark/favorites like system: alias Cons: Too specific (every new favorite requires a new alias...although you could in theory make an alias that echo append your dir as a new alias, which would be sort of clever). Can't nest favorites in folders (can't think of a simple solution to this outside of heavy config scripting). links Cons: Clutter directory make ls a headache. pushd/popd Cons: Non-permanent (without shell config file scripting), can't nest favorites in directories, etc. Granted I have multiple ideas for making my own non-standard solution, but before I have at it I wanted to get some perspective on what's out there and if there is nothing, what is a recommended approach. Does anyone know of such a favorites/bookmark-like terminal solution?

• Set Thunderbird "from" address by incoming "to" address

  - by user293698

  I have configured my email server to cache all email to my mailbox. So [email protected] and [email protected] go to one mailbox. Every forum, registration, and guy get their own address for sending me emails so I can deliver it to /dev/null if anyone start spamming. That's the working setup. Now the problem: If I reply to a message, then Thunderbird always sets my default Identity as sender. I know I can add additional identities, but I don't want to add every address. How can I configure when a email is sent to [email protected], I answer with [email protected].

• Migrating Gmail to Office 365

  - by user218699

  Good Morning, I have been setting up Office 365 for my organization. We are currently using Gmail. I have synced our local Active Directory server w/ Office 365, as well as our domains. The problem I am having has to do with migrating mailboxes from Gmail to Office 365. I have been using this article to walk me through the process: http://technet.microsoft.com/en-us/library/dn568114.aspx The issue arises when I begin to sync the mailboxes. Currently I have been trying to sync my own mailbox as a test. The synchronization process has been going on for about 15 hours (for just one mailbox) with no errors or any information given by Office 365, other than the "Syncing" status on the migration page in the Exchange Admin Center. Is syncing a single mailbox supposed to take this long, or have I missed a step? Thanks!

• Is it possible to spoof the From: field in Outlook?

  - by tsvallender

  I am wondering if it is possible to change the From: field (not just the reply-to) in Outlook (specifically in the 2010 beta, but also interested in other versions). I am just moving over from Linux and am used to being able to do this quite simply in some clients. At first I thought it was the option of "Other E-Mail address" on the From drop down menu in a compose window, but that seems to do... nothing! I want to be able to do this so I can have email look like it comes from a domain I own but do not wish to run an SMTP server on.

• Running a home mail server using dynamic dns

  - by user4009

  Hi, Is it possible to run an email server on my home box using dynamic dns? The scenario is, I want to auto cc all incoming and outgoing emails from my one account to another, from some server side config instead of configuring email clients for rules. I have tried Google Apps Mail but it doesn't allow auto cc of outgoing emails. After having read tons of blogs, forum messages etc (hope I have been reading the correct info :) ) the only option to achieve what I am needing is to setup my own mail server, but the cost of getting a static IP doesn't fit my budget. Please can someone point me in the correct direction. Platform doesn't matter, I can setup a Windows or Linux server. Many Thanks

• Where are Wireless Profiles stored in Ubuntu

  - by LonnieBest

  Where does Ubuntu store profiles that allow it to remember the credentials to private wireless networks that it has previously authenticate to and used? I just replaced my Uncle's hard drive with a new one and installed Ubuntu 10.04 on it (he had Ubuntu 9.10 on his old hard drive. He is at my house right now, and I want him to be able to access his private wireless network when he gets home. Usually, when I upgrade Ubuntu, I have his /home directory on another partition, so his wireless profile to his own network persists. However, right now, I'm trying to figure out which .folder I need to copy from his /home/user folder on the old hard drive, to the new hard drive, so that he will be able to have wireless Internet when he gets home. Does anyone know with certainty, exactly which folder I need to copy to the new hard drive to achieve this?

• Features and components used in Google Chrome taken from Firefox

  - by tobylane

  20 Things I Learned About Browsers and the Web says, in the following passage, that Chrome has taken things from Firefox: Open-source software plays a big role in many parts of the web, including today’s web browsers. The release of the open-source browser Mozilla Firefox paved the way for many exciting new browser innovations. Google Chrome was built with some components from Mozilla Firefox and with the open-source rendering engine WebKit, among others. In the same spirit, the code for Chrome was made open source so that the global web community could use Chrome’s innovations in their own products, or even improve on the original Chrome source code. Does anyone know what those components are?

• Developing Good Contacts

  There are millions of was you can develop good networking contacts, but you must be open to meeting new people. In the information technology industry, everyone is a potential client. So any place you can meet people is a good place to develop good networking contacts. Here are a few examples Online Discussion Forums – Online forums are a great place to show your knowledge of a subject and allow you to meet people that share your same interests Blog Networks – Allowing others to read your thoughts and comment on them. In addition, you can so the same on other blogs with in the network. Networking Sites – Networking sites are a great way to find new contacts based on your current contacts because you can share common friends, and possibly common interests Volunteering – Volunteering is a great way to meet new contacts, and you can help others at the same time Civic Organizations – Participating in organizations or clubs like the Lions Club, Rotary Club, and religious affiliated organizations because you can meet people of all walks of life, and can share and contribute ideas for common goals Chamber of Commerce – This is another great way to meet contacts especially if you are interested in starting your own business. The chamber is a great way to meet other business oriented people who are always looking to collaborate and improve their business. Family and Friends – Family and friends are another excellent to meet new contacts, because they can always be on the lookout for opportunities for you. For example your brother hears that a friend of his needs a new website, so he gives him your number and highly recommends you. This is really good because the potential client is looking for the service you can perform, and you where already highly recommend.

• Late feedback

  - by Sveta Smirnova

  MySQL Community team asked me to write about Devconf 2013 few months ago. Conference was in June, 2013, but I remembered about this my promise only now: month later after my participating in MySQL Connect and Expert Troubleshooting seminar (change country to United Kingdom if you see blank page). I think it is too late for the feedback, but I still have few thoughts which I want to record.DevConf (former PHPConf) always was a place where I tried new topics. At first, because I know audience there very well and they will be bored if I repeat a story which I was telling last year, but also because it is much easier to get feedback in your own native language. But last years my habit seems started to change and I presented improved version of my 2012 MySQL Connect talk about MySQL backups. Of course, I also had a seminar with unique topic, made for this conference first time: Troubleshooting MySQL Performance with EXPLAIN and Using Performance Schema to Troubleshoot MySQL. And these topics, improved, were presented at the expert seminar. It is interesting how my habit changes and one public speaking activity interferes next one.What is good about DevConf is it forces you to create new ideas and do it really well, because audience is not forgiving at all, so they catch everything you miss or prepared not good enough. This can be bad if you want to make a marketing-style topic for free, but allows to present technical features in really good details: all these sudden discussions really help.In year 2013 Oracle had a booth at the conference and was presented by a bunch of people. Dmitry Lenev presented topic "New features of replication in MySQL 5.6" and Victoria Reznichenko worked on the booth. What was new at the conference this year is greater interest in NoSQL, scale and fast development solutions. This, unfortunately, means not so huge interest in MySQL as it was earlier. However, at the same time, "Common" track was really MySQL track: not only Oracle, but people from other companies presented about it.

• routing weirdness - traceroute 'vanishes' en route

  - by The Journeyman geek

  I'm attempting to set up one of my boxes as a server (again), but i'm having some odd connection issues- the box itself connects fine to the internet, but trying to connect to my external ip address seems to result in the trace getting 'lost' partway. http://pastebin.com/HCQAGbvn - this is a traceroute from another system that's connected to another ISP - starhub is my own one, while i have another system that i have access to on singtel. I'm wondering if my ISP is messing around with routing, or is something very odd going on. As you note, the traceroute dosen't reach me, but if it helps, i use a dd-wrt router. edit: Facepalmishly, turning the firewall on my router on and off fixed it. I don't get why it dropped off at different ip addresses each time, or why the router set it self to block.. everything, or why it affected the ipv6 tunnel as well.

• unable to kill process / logout on windows server 2003

  - by vitalik

  My own console .net application stuck in a "ghost" stage. It just shows a window that i can't close. It doesn't show up as a process in the task manager. when i try to "find windows process" using Process Explorer (from sysinternals) it says there is no process that owns that window or something like that. The problem is that it doesn't allow me to logout or reboot the server (remotely) because logoff process keeps waiting on that window to close. shutdown /r /f also is stuck waiting for it. I can probably have somebody go an reboot the server but i'd like to know if there is a way to close that process, close that session or force logout remotely. This is windows server 2003, but i had the same issue on XP just a few days ago.

• Shader compile log depending on hardware

  - by dreta

  I'm done with the core of my graphics engine and I'm testing it on every platform I can get my hands on. Now, what I noticed is that different drivers return different shader and program compile log content. For example, on my friend's laptop if you successfuly compile a shader then the log is simply empty. However on my PC I get some useful information along with it. So if I compile a vertex shader, I'll get: Vertex shader was successfully compiled to run on hardware. Which isn't that impressive, but is what happens when I compile a program. On my friend's computer the log is empty, since the program compiles. However on my own computer I get: Vertex shader(s) linked, fragment shader(s) linked. Which is awesome, because I'm attaching a geometry shader with 0 (I have a geometry shader file with trash, so it doesn't compile and the pointer is set to 0), and the compiler just tells me which shaders linked. Now it got me thinking, if I was going to buy a graphics card, is there a way for me to get the information about whether or not I'll get this "extended" compile information? Maybe it's vendor specific? Now I don't expect an answer TBH, this seems a bit obscure, but maybe somebody has any experience with this and could post it.

• Setting up a server with only subdomains, any connection to top level goes to main server on another IP?

  - by Anagio

  I'm developing a web app where users will have their own sub-domain to login to and use the application. I'm running wordpress for the main website to manage the public / front end. Our application is developed in zend framework. The zf project is currently in a subfolder on the main server. I'd like to place the zend framework project onto another server (different IP) and keep it separate from the the wordpress front end www.domain.com site. The zf application server will run nginx. I'm not sure how to setup a server to run strictly sub domains. Setting up the virtual hosts in the configuration file is no problem. To give the users username.domain.com. But what about the main default configuration file? How would that be configured since the top level domain is technically another server (wordpress) on another IP?

• Converting Powerpoint to PDF solutions?

  - by OWiz

  I asked a version of this question earlier, but I'm in need of other solutions, so this is a more pointed question. I'm in need of a server-based solution for converting ppt files to pdf files. This solution can either sit on the current web server as a console command-triggered service, it can be integrated into the C# code of the web all, or it can be it's own server. It also can't be based off of Libreoffice or Openoffice, as those two have problems converting SmartArt. I'm currently using Libreoffice. I've tried Powerpoint console commands combined with a PDF driver but I can't get that to work from C#. I've tried a .vbs script, but that briefly opens the powerpoint window.

• How do I set the TEMP environment variable for the "Network Service" user?

  - by Chris Phillips

  We have a system that uses Path.GetTempFile and Path.GetTempPath calls to work with temporary files fairly frequently. This system also runs as the "Network Service" user. We're finding that we're running out of room on the C drive (for other issues, our temp files are cleaned up correctly) and would like to be able to move the temp directory to a different drive. The easiest solution to this seems to be to change the TMP or TEMP environment variables for the Network Service user, but I only seem to be able to set my own user or the "system" variables that are overwritten by the Network Service user profile. How do I set these variables for the Network Service user?
