• Tracking my home IP from anywhere on the internet?

  - by oKtosiTe

  I have an ISP that serves semi-permanent IPv4 addresses. They can't promise fixed IP addresses, but unexpected changes are quite rare. This begs me to ask however: what would be the easiest/most reliable way to track my home IP address so I can access my (Windows 7) home server even in the case of an address change? Please note: for reasons that I don't want to go in to, I'd like to avoid using any "dynamic DNS" type services. Instead I'd prefer some way to perhaps have the home server leave an occasional/triggered "address stamp" on a remote, off-site server (by SSH, HTTP post or similar, preferably over an encrypted connection).

• What is a descriptive name for a web service that responds with plain text?

  - by Rich Shealer

  I'm looking for the proper name for a web service that responds with text as opposed to XML. As an example this "cardServer" service will return 5 cards for a poker hand. http://hostname:8080/cardServer/deal/Game=Poker&Qty=5 The result could look like this: Card1=Ad Card2=Kc Card3=Ts Card4=5d Card5=3d The real world example is not as trivial, but the concept is the same. Parameters if any are passed as POST variables. We currently parse the response into a string list and use the values. The process works just fine. What I'm wondering if this service method has a name that has easier tools to deal with the responses and therefore did we reinvent the wheel? For the record the service was provided and maintained by a customer.

• How to restore default iPod playlists on Amarok?

  - by obvio171

  I wanted to "reset" the collection on my iPod and ended up accidentally deleting, through Amarok, all the playlists, including the default ones like "Most Played" and "Highest Rated". Since these are dynamic playlists with a special meaning for iPod, I don't think creating new, normal playlists with the same name will bring their special behavior back. How do I restore them with the same dynamic functionality? Is there a way to do that on Amarok? Rhythmbox? GTKPod? Command line? P.S.: not entirely sure what the policy about iPod questions are, but this one in particular seems to me to be very computer-related because, although it's about interfacing with a device, everything has to be done on my computer, using standard PC libraries/programs, etc. If it's still off-topic, please point me to where I could post it.

• How to charge an iPhone on a Windows PC without Installing iTunes

  - by Martin Hollingsworth

  I want to be able to charge my iPhone on my work computer, which is running Windows Server 2008 SP1 64-Bit. When I plug the iPhone in with the USB cable, it will not charge. Windows attempts to locate a driver for the device but only comes up with a generic Camera device and even if I allow that to be installed, the iPhone still does not charge. I have checked the computer's BIOS settings and did not find anything relating to power on the USB devices. I also tried this on ports at the back of the computer in addition to those on the front. The PC is a Dell Optiplex 780. As far as I can tell USB devices do not charge unless Windows has installed an appropriate driver. Since it is a work computer I do not want to install iTunes which does include a driver. I have a workaround that I will post as an answer for reference.

• XNA - Obtaining depth from the scene's render target?

  - by user1423893

  I'm currently rendering my scene to a render target so it can be used for rendering methods such as post processing and order independent transparency. rtScene = new RenderTarget2D( GraphicsDevice, GraphicsDevice.PresentationParameters.BackBufferWidth, GraphicsDevice.PresentationParameters.BackBufferHeight, false, SurfaceFormat.Rgba64, DepthFormat.Depth24Stencil8, // Requires a depth format for objects to be drawn correctly (e.g. wireframe model surrounding model) 0, RenderTargetUsage.PreserveContents ); I am required to use RenderTargetUsage.PreserveContents so that the same render target can be rendered to multiple times, once for each of the draw methods below. DrawBackground DrawDeferred DrawForward DrawTransparent The problem is that DrawTransparent requires a copy of the scene's depth as a texture. Is there any way to obtain this from the scene render target above (rtScene)? I can't have more than one render target with RenderTargetUsage.PreserveContents as this causes problems on hardware such as the XBOX 360, so rendering the depth to a separate render target at the same time as I render the scene isn't possible as far as I can tell. Would I be able to get around this problem by "Ping-Ponging" two render targets (using the more compatible RenderTargetUsage.DiscardContents) and using the result for the depth texture?

• How to make Windows display application crashes in the console?

  - by Name is carl

  I'm developping a C application on Windows 7 64 bits, and each time it crashes I get the following dialog: I would prefer something more "old school" with the complete error dumped in the console. Something like > HelloWorld The application has crashed in somedll.dll for some Horrible C reason. I have an error code 0x4445506 And a kinda stacktrace And walls of hexa 0x4445506 0x4445506 0x4445506 0x4445506 0x4445506 0x4445506 0x4445506 0x4445506 0x4445506 0x4445506 0x4445506 0x4445506 0x4445506 0x4445506 0x4445506 0x4445506 0x4445506 0x4445506 0x4445506 0x4445506 0x4445506 0x4445506 0x4445506 0x4445506 0x4445506 0x4445506 0x4445506 0x4445506 0x4445506 0x4445506 Is there a way to get that? Should I run my application with a command line debugger ? Note: should I post this on Stackoverflow instead?

• Windows 8 Secureboot: How do you bootup from another device such as cd/dvd drive or usb flash etc.?

  - by Victor T.

  On PC's and laptops running an older OS, this is just a simple matter of going into the BIOS and setting the boot sequence and putting the boot cd/dvd in the drive. In many cases you can even just hit one of the F* function keys to bring up the boot sequence menu on-the-fly during POST. The main problem I'm running into is that other devices besides the primary HD is disabled when SecureBoot is enabled. So far the only way I've gotten it to work is to disable SecureBoot and enable something called legacy mode. Needless to say this make it difficult to boot things like OS recovery tools, PartitionHD backups, Linux LiveCD's and a bunch of others. Is there another procedure for doing this since it seems to mess up the Windows 8 install? By mess up I mean that after re-enabling SecureBoot and starting Windows 8 normally, the OS goes into a 'preping repair phase' for some reason that takes forever to complete before getting into a usable desktop.

• Implementing my Entity System. Questions about some problems I have found.

  - by Notbad

  Hi!, Well during this week I have deciding about implementation of my entity system. It is a big topic so it has been difficult to take one option from the whole. This has been my decision: 1) I don't have an entity class it is just an id. 2) I have systems that contain a list of components (the list is homegenous, I mean, RenderSystem will just have RenderComponents). 3) Compones will be just data. 4) There would be some kind of "entity prototypes" in a manager or something from we will create entity instances.Ideally they will define the type of components it has and initialization data. 5) Prototype code to create an entity (this is from the top of my head): int id=World::getInstance()->createEntity("entity template"); 6) This will notify all systems that a new entity has been created, and if the entity needs a component that the system handles it will add it to the entity. Ok, this are the ideas. Let's see if some can help with the problems: 1) The main problem is this templates that are sent to the systems in creation process to populate the entity with needed components. What would you use, an OR(ed) int?, a list of strings?. 2) How to do initialization for components when the entity has been created? How to store this in the template? I have thought about having a function in the template that is virtual and after entity is created an populated, gets the components and sets initialization values. 3) Don't you think this is a lot of work for just an entity creation?. Sorry for the long post, I have tried to expose my ideas and finding in order other could have a start beside exposing my problems. Thanks in advance, Notbad.

• lighttpd not reliable

  - by schneck

  Hi there, I have a lighttpd running which serves a django-based webservice. It was running well for some months, but from today on, it returns a 410 sometimes, and sometimes fails silently. To test, I make a curl-call, which most time runs fine; it returns some json test-data. Some times. however, it does not return any data, but the call seems to have run well, since I don't get an error code. When I post to my webservice via third-party-packaged like boto, I sometimes get a "410 gone" - but I do not find any entry in the lighttpd error log. Any ideas what the problem could be or how to avoid this? Thanks a lot

  I have an iMac running Mac OS X 10.5.8 and the RDP Connection Client 2.0.1. http://salle.dyndns.org/misc/rdp%5Fproblem1.png When I try to connect to a Windows 2003 Server on the same network I get a dialog saying "Remote Desktop Connection cannot verify the identity of the computer that you want to connect to".

• Ubuntu Server 12.04 as a router. Problem with DNS?? Or Routing table?

  - by Lorenzo

  I have a virtualbox lab made up of 4 Windows 2008 R2 servers (DC/DNS,SQL,SHAREPOINT, EXCHANGE) that are configured with static ip addresses with NIC's attached to Internal network. Everything works. I had the requirement to execute some tests that also access external services available on the internet. To keep things clean and similar to the production environment I have installed another VM, with Ubuntu Server 12.04 64 bit and configured (I hope) to work as a router like described on this post. This VM has two network interfaces: first is Bridged with the host and is used as a WAN connection and the other one attached in the Internal Network with its own static IP address on the internal network subnet. But actually the Windows servers does not connect to the internet while the unix one connects. I did a route command. this is the result: Kernel IP Routing table Destination Gateway Genmask Flags Metric Ref Use Iface default 10.69.121.1 0.0.0.0 UG 100 0 0 eth0 10.69.121.0 * 255.255.255.0 U 0 0 0 eth0 192.168.83.0 * 255.255.255.0 U 0 0 0 eth1 Can somebody help me with this configuration? :) Thanks! Addendum: I forgot to mention that one of the windows server hosts a DNS service for which I should maybe configure a forwarding server but I do not exactly know which server to forward on... :(

• How do we increase the maximum allowed HTTP GET query length in Jetty?

  - by Mike

  We are using Jetty to run an Apache Solr index. We've had some queries that have grown way beyond the previously expected maximum length, and are now having issues wehre most queries are not returning any data because the URL gets truncated. These requests are not being made through a browser, they're being made programmatically using the Apache_Solr_Service PHP library. The application is expecting queries to come in as HTTP GET requests, so simply switching to a POST will not solve this problem. How can we increase the maximum allowed HTTP GET query length in Jetty? Thanks!

• Redirection & SEO related stuff while moving to a new blog

  - by Karshim Kanwar

  I have a WordPress blog and recently I have setup a new blog lets call the old blog as blog old and new blog as blog new. What I did is moved the content, photos, pictures and all 250 posts from blog old to blog new. Both the blog name are changed as they are pointing to different domain names! I read helpful things in this site itself at here. I will no longer use blog old, moreover I am concerned about the SEO of the blog new. The blog new is fairly new (just 24 hours and no pages have been indexed in Google). I have done the following stuff: Deleted all the post share at Facebook fan Page, Twitter profile, Google+ page and Finally deleted the fan page/Twitter, Google+ page. Edited the link backs of old blog in the blog new. The question I have is: How do I prevent duplicate content issues? Do I go straightaway and delete all the posts in blog old? Should I start sharing the blog posts in blog new? Should I submit the new site to Webmaster Tools or wait for few weeks? Every comment here is appreciated! What issues can I face relating to SEO?

• Windows 8.1 - unfixable grub

  - by Nick

  I have a Gigabyte laptop that came with secure boot and windows 8. After a bit of battling, I managed to get my dual boot with Ubuntu 13.10.. Anyway, I upgraded zindows to 8.1, now grub is gone. I restarted from a live CD and chrooted to my drive. I used boot-repair multiple times (with successful output) both in default and with some advanced options; also reinstalled grub manually... Each time it tries once to boot to grub but gives a message for a very short amount of time. I recorded it and it is a regular bios message "Rebbot and Select proper Boot device of Insert Boot media in selected boot device and press a key" I even tried something called EasyBCD under winblows, it shows the correct boot options, but same there, it is unable to make the linux partition fire up. Anyway, no way to boot my linux box. Does anyone have an idea how to fix this? No need to redirect me to another post with grub reinstall or boot-repair, seen them all... I am thinking of trying this other boot loader, refind, to see if it works http://www.rodsbooks.com/refind/index.html Also re-reading this bios message, I'm thinking my partition might not have a boot flag anymore... I'll try that too with parted. Although both grub and win 8 are supposed to fire up from the same boot partition (the EFI one) Please help! thx

• Facebook - Isn't this a big vulnerability risk for users? (After Password Change)

  - by Trufa

  I would like to know you opinions as programmers / developers. When I changed my Facebook password yesterday, by mistake I entered the old one and got this: Am I missing something here or this is a big potencial risk for users. In my opinion this is a problem BECAUSE it is FaceBook and is used by, well, everyone and the latest statistics show that 76.3% of the users are idiots [source:me], that is more that 3/4!! All kidding aside: Isn't this useful information for an attacker? It reveals private information about the user! It could help the attacker gain access to another site in which the user used the same password Granted, you should't use use the same password twice (but remember: 76.3%!!!) Doesn't this simply increase the surface area for attackers? It increases the chances of getting useful information at least. In a site like Facebook 1st choice for hackers and (bad) people interested in valued personal information shouldn't anything increasing the chance of a vulnerability be removed? Am I missing something? Am I being paranoid? Will 76.3% of the accounts will be hacked after this post? Thanks in advance!! BTW if you want to try it out, a dummy account: user: [email protected] (old) password: hunter2

• Windows 2008 x64 displays SP1 when SP2 is installed

  - by Graham Powell

  After setting up a Windows 2008 x64 server (not R2), I installed a number of Microsoft updates. After installing these updates, the computer reports that it has SP1 installed, not SP2. I believe the culprit is KB917607, which allows Windows 2008 to display .hlp files. Now I have to upgrade Internet Explorer on this server, and it won't install without SP2. I am very leery about reinstalling SP2, as I have installed a large number of post-SP2 updates, and I've had issues after reinstalling SP2 in similar circumstances. How can I fix Windows so it reports the correct service pack?

• Multilingual sites and Google search results, do subfolders really work?

  - by AWinter

  About three months ago we added an English version of our, previously Japanese only, site http://www.clubberia.com under the subfolder http://www.clubberia.com/en/ we've tried to follow the sometimes incomplete best practices laid out by Google by adding alternate tags to all pages that are currently translated. The top page for instance has the following meta tags for language. <link rel="canonical" href="/"> <link rel="alternate" hreflang="ja" href="/"> <link rel="alternate" hreflang="en" href="/en/"> While the English main page under /en/ has <link rel="canonical" href="/en/"> <link rel="alternate" hreflang="ja" href="/"> <link rel="alternate" hreflang="en" href="/en/"> We also have these alternate languages setup in the sitemap. (as per Google's recommendations) http://www.clubberia.com/sitemap.xml It seems however that Google absolutely refuses to show the English top page in results when the user is using English at google.com if you search for "clubberia" you'll, as of this post, get the Japanese description and a title that Google has apparently invented instead of the title and description in the meta-tags for the /en/ index page. Does anyone have any experience with subfolders actually working to affect search results? Am I being too impatient, or possibly doing something incorrect? Should we just give up on subfolders and push to subdomains (not the prettiest option)?

• Interested in scp recipe for sftp [closed]

  - by GJZ

  You wrote in a reply this Blockquote The problem is that sftp runs as the user's id -- first, the sftp client ssh's into the target host as the given user, then runs sftp-server. Since sftp-server is running as a regular user, it has no way to "give away" a file (change owner of a file). However, if you are able to use scp, and assign a key pair to each user, you can get around this. This involves adding a user's key to root's ~/.ssh/authorized_keys file, with a "command=" parameter to force it to run a script that sanitizes and alters the arguments of the server-side scp program. I've used this technique before to set up an anonymous scp dropbox that allowed anyone to submit a file, and ensure that no one could retrieve submitted files and also prevent overwrites. If you are open to this technique, let me know and I'll update this post with a quick recipe. We are interested in this scp quick recipe for our community services file sharing. Best Regards, Gert Jan Zeilstra

• A Web Service to collect data from local servers every hour

  - by anilerduran

  I'm trying to find a way to collect data from different servers around the world. Here are the details: There is only one single PowerShell script on servers that encrypts data (simple csv file) and sends with preferred method (HTTP/HTTPS Post could be) There is no more control on that servers. Can't install any service, process etc. Just I can configure script to execute every hour. This script also will have encrypted username/password/license key for every server. Script will compress data and send to me with these information. So I need a service (I'm not sure if Web Service is the rigth solution) on the cloud that will help me to: Will get data that is sent from servers using a method. Will authenticate request to recognize sender using license key/username/password and most importantly, Will redirect/send this filecab to my SQL Server on the cloud (Azure). Also it should seperate data according to customer information in license key. So every data for every customer will be stored in dedicated DB/Tables on my SQL All the processes above should be completed automatically. No way for manual steps. Question: A Web Service (SOAP or Restful) is the rigth solution for that?

• 404s on password protected content

  - by tjb1982

  I'm new to WordPress and SEO, generally, but we've been running into problems with our site that don't seem to make sense to me. The problem is that our editor likes to schedule posts and/or mark them private until she is ready to make them public, but somehow Google is crawling these posts and getting 404s (because they are password protected). How does Google know they exist in the first place? I checked the sitemap.xml file and don't see a record of the post. One of the offending posts was marked public, but is scheduled for a future date. Could that have something to do with it? I've tried to Google the answer, and I came up with a good amount of reassurance that this won't hurt the site, but I'm still wondering how it's happening in the first place. It's hard because I don't know exactly what the editor's workflow is. Is it possible she's posting publicly first and then revising it to be private only after it's too late? Does anyone know how Google finds WordPress URLs it shouldn't have access to?

• Which is the best way to sync and share contacts and calender between Thunderbird, iPhone and Android?

  - by bensch

  I would like to keep my contacts and a calendar synchronized between several desktops and cellphones. Is there a way to achieve this without using Google or similar organisations? I want to keep my data protected and safe, so an encrypted transfer would be useful. Do i need to install a service on my own rootserver? or are there any services available, that are safe? I read this post, but there is not mentioned not to use Google: Thunderbird contacts sync so no solutions with SoGo or LDAP. maybe Zimbra is a solution? or Funambol? I tried kolab, but had some unsolveable problems.

• Laptop white screen on power-up. Still displays via HDMI output

  - by Inno

  my wife's laptop recently started displaying a white screen. It doesn't show post or anything, just a white screen when it's powered on. However, it works normally with HDMI output to our television. I took it apart and fiddled with both ends of the display cable, but I either didn't fiddle correctly or that's just not the problem. I also noticed that the screen won't turn off anymore when the laptop is closed. Is there a name for the mechanism that controls this function, so I can try and locate it? My guesses are that the problem lies with the screen itself or the display cable, but I'm curious if there's anything else I might be overlooking. Also of note is that the left hinge is partially broken. The corner of the plastic computer case broke off, so the hinge is exposed and doesn't stay in place. I've tried holding it in place, wiggling it around, tapping various parts of the computer, but the white screen remains.

• How to rewrite using htaccess if the file exists in another folder?

  - by Jack

  We are trying to rewrite to another folder if the file does not exist in the document root, but does exist in the other folder. The other folder is in a completely different location, which is located using "Alias" in the vhosts. So, what we have so far (from this post How to rewrite URI from root if file exists in folder?) is: RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_URI} !^/legacy/ RewriteRule ^(.*)$ legacy/$1 [QSA,L] This works to an extent, but seems to direct everything to the legacy folder, not just when the file doesn't exist in the first location and does exist in legacy. Thanks in advance for any help, Jack.

• PHP 5.4.7 and Apache 2.2 Trouble under Windows XP

  - by IssamTP

  I'm trying to setup a test enviroment on a virtual machine running Windows XP Home (totally updated), with Apache 2.2 and PHP 5.4.7. I can load the PHP 5 module inside httpd.conf and if I don't rename php.ini-DEVELOPMENT (or -PRODUCTION) file to php.ini, the engine works fine. This basic configuration doesn't have MySQL module loaded, so I have to rename rename the .ini-DEVELOPMENT into .ini and edit as follows: ; Directory in which the loadable extensions (modules) reside. ; http://php.net/extension-dir ; extension_dir = "./" ; On windows: extension_dir = "C:/php/ext/" ... extension=php_mysql.dll extension=php_mysqli.dll Restart Apache with no problems and... all I can get is a blank page. Where can I see some error or do you know where is the trouble? Tell me if I need to post something else to give you more details.
