• Trouble with StreamReader

  - by John

  Alright so here is what I have so far, List<string> lines = new List<string>(); using (StreamReader r = new StreamReader(f)) { string line; while ((line = r.ReadLine()) != null) { lines.Add(line); } } foreach (string s in lines) { NetworkStream stream = irc.GetStream(); writer.WriteLine(USER); writer.Flush(); writer.WriteLine("NICK " + NICK); writer.Flush(); writer.WriteLine("JOIN " + s); writer.Flush(); string trimmedString = string.Empty; CHANNEL = s; } Unfortunately when my IRC dummy enters a room with a password set it writes out the password, if I make it change channel with a command such as #lol test test being the password, since CHANNEL = s; it writes out the password with the command writer.WriteLine("PRIVMSG " + CHANNEL + " :" + "Hello"); That is the only way to write out to IRC so is there a way for the "CHANNEL" to only be the start of the text and just #lol so it doesn't write out the password? I hope you understand my problem.

• Should I use DATE and TIME as fields rather than DATETIME

  - by whitstone86

  I have a project on going for a TV guide, called mytvguide in the database - I use PHPMyAdmin. This is the structure for one table, which is called tvshow1: Field Type channel varchar(255) date date No airdate time No expiration time No episode varchar(255) setreminder varchar(255) but am not sure how to get DATE, TIME to work with the pagination script (below is the script, which works for the version with DATETIME): http://pastebin.com/6S1ejAFJ However, although the DATETIME one works - it shows programmes that air on the day itself like this: Programme 1 showing on Channel 1 2:35pm "Episode 2" Set Reminder Programme 1 showing on Channel 1 May 26th - 12:50pm "Episode 3" Set Reminder Programme 1 showing on Channel 1 May 26th - 5:55pm "Episode 3" Set Reminder but I'm not quite sure how to replicate that for the fields that use DATE, TIME functions as seen above. Any advice on this is appreciated, thanks!

• How can I specify custom folders for file-browsing in Metro Apps?

  - by klyonrad

  Whenever you use an Metro app and you want to import some files there is a little file browser. Like this: A lot of folders possible; however there is a folder that is very important: The personal Dropbox. How can I add this folder as a "favorite" in this view? Always browsing through the whole filesystem is slow in the Metro Interface. I realize I could make symlinks for all the typical Dropbox folders but that's simply annoying and there has to be another way (just like it's possible to "hack" the "Send To..." options for the context menu.

• How to pass variables to slot methods in QT?

  - by Neko

  Hi. I'm making a little chat messenger program, which needs a list of chat channels the user has joined. To represent this list graphically, I have made a list of QPushButtons, which all represent a different channel. These buttons are made with the following method, and that's where my problem kicks in: void Messenger::addToActivePanels(std::string& channel) { activePanelsContents = this->findChild<QWidget *>(QString("activePanelsContents")); pushButton = new QPushButton(activePanelsContents); pushButton->setObjectName("pushButton"); pushButton->setGeometry(QRect(0, 0, 60, 60)); pushButton->setText(""); pushButton->setToolTip(QString(channel.c_str())); pushButton->setCheckable(true); pushButton->setChecked(false); connect(pushButton, SIGNAL(clicked()), this, SLOT(switchTab(channel))); } (activePanelContents is a QWidget that holds the list.) The point is that each button should call the switchTab(string& tabname) method when clicked, including the specific channel's name as variable. This implementation doesn't work though, and I haven't been able to find out how to properly do this, even after reading several pages on it on the internet. Can anybody please tell me how to do this? It'd be greatly appreciated, as always. :)

• How to configure OpenVPN server to use custom default gateway?

  - by Arenim

  I have a vpn server at address 10.1.0.2 and the server have another ip in it's network -- 10.0.0.2 in his subnet (it's a tun2socks router). But default server's gateway is NOT 10.0.0.2 (and it's ok) but another external IP. I want all the client's traffic to be forwarded through this ip address -- 10.0.0.2. Here is part of my server's config: dev tap0 server-bridge 10.1.0.1 255.255.255.0 10.1.0.50 10.1.0.100 push "route 10.0.0.0 255.255.255.0" ; now client can ping 10.0.0.2 push "redirect-gateway def1 bypass-dhcp" push "dhcp-option DNS 10.1.0.1" push "dhcp-option WINS 10.1.0.1" in fact i want some like push "redirect-gateway 10.0.0.2" How can I achieve this?

• How do I use runit to manage my custom made node.js service?

  - by apphacker

  My service is very basic, just an HTTP service. I just want it to restart automatically when it quits because of an error. I figured I could use runit to do this, but it seems like the runit docs mostly talk about how to convert your entire init.d to runit. I want to preserve init.d and just use runit for my one service. I was looking at these docs. Thanks. EDIT: I think this is pointing in the right direction, I guess I just need to know how to make a service now.

The structure is following: - root/channel_1/service_1/2014-05-21/file_54544654541.xml - root/channel_1/server2_2/2014-05-20/file_74272172.xml - root/channel_1/service_3/2014-05-22/file_45456546.xml - root/channel_2/service_4/2014-05-23/file_78754456.xml - root/channel_2/service_5/2014-05-24/file_546546546.xml my main problem is to find particular string in these xml files. Lets say, i know the channel name but i dont know the service name under which my particular string should be present. Also i know the date. So in search i want to enter the channel name the date and string.

Either by bash or perl? Any help would be appreciated thanks

• Is there a way to create a custom installer package to do batch installs of a bunch of programs at o

  - by user37860

  Basically I want to create a file which will automatically install a bunch of files without having to manually install each of them (i.e. Flash, Adobe Reader, MS Office, etc.). I'm guessing the easiest way to do this would be to create a batch file but I don't have much experience with the scripting side of things. I remember seeing a website at one point that would do this sort of thing for you but I'm not sure if that could be used offline or not. Thanks in advance...just looking to make things a bit more streamlined on new builds without the costs associated with imaging software. Thanks!

  - by cc1001

  I'm developing a standalone custom registry, custom login portlet, and custom profile portlet for Websphere Portal 6.1. Some existing users have not completed one or more required fields in their profiles. The next time these users log in successfully, how can I get the portal to redirect them to the custom profile portlet before giving them access to the rest of the site?

• Apache Virtualhosts with PHP and custom logs - how to isolate PHP errors?

  - by Repox

  I'm trying to setup a simple hosting enviroment for my application on an Ubuntu server. I created a virtualhost like this: <VirtualHost *:80> ServerAdmin [email protected] ServerName www.example.com ServerAlias example.com DocumentRoot /home/owner/example.com/docs <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /home/owner/example.com/docs/> Options -Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog /home/owner/example.com/logs/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

How can achieve this?

• What if any free video player for windows can I set a custom frame buffer for streaming over the wifi?

  - by user268883

  I currently use DAUM PLayer (Pot Player) but I have problems streaming video to my laptop unless it is plugged into the network. An easy fix (so I thought) would be to find a player were I could adjust the cache / buffer so say 5 mins+ is read to the local Hdrive and then played from there... I can not work out how to do this in any player I have VLC, MPCHC and DAUM installed. All I want to do is increase the file buffer so X amount of the networkfile is copied to the local drive and then played... so all stuttering is stopped? How do I do this?

• .net remoting - Better solution to wait for a service to initialize ?

  - by CitizenInsane

  Context I have a client application (which i cannot modify, i.e. i only have the binary) that needs to run from time to time external commands that depends on a resource which is very long to initialize (about 20s). I thus decided to initialize this resource once for all in a "CommandServer.exe" application (single instance in the system tray) and let my client application call an intermediate "ExecuteCommand.exe" program that uses .net remoting to perform the operation on the server. The "ExecuteCommand.exe" is in charge for starting the server on first call and then leave it alive to speed up further commands. The service: public interface IMyService { void ExecuteCommand(string[] args); } The "CommandServer.exe" (using WindowsFormsApplicationBase for single instance management + user friendly splash screen during resource initializations): private void onStartupFirstInstance(object sender, StartupEventArgs e) { // Register communication channel channel = new TcpServerChannel("CommandServerChannel", 8234); ChannelServices.RegisterChannel(channel, false); // Register service var resource = veryLongToInitialize(); service = new MyServiceImpl(resource); RemotingServices.Marshal(service, "CommandServer"); // Create icon in system tray notifyIcon = new NotifyIcon(); ... } The intermediate "ExecuteCommand.exe": static void Main(string[] args) { startCommandServerIfRequired(); var channel = new TcpClientChannel(); ChannelServices.RegisterChannel(channel, false); var service = (IMyService)Activator.GetObject(typeof(IMyService), "tcp://localhost:8234/CommandServer"); service.RunCommand(args); } Problem As the server is very long to start (about 20s to initialize the required resources), the "ExecuteCommand.exe" fails on service.RunCommand(args) line because the server is yet not available. Question Is there a elegant way I can tune the delay before to receive "service not available" when calling service.RunCommand ? NB1: Currently I'm working around the issue by adding a mutex in server to indicate for complete initiliazation and have "ExecuteCommand.exe" to wait for this mutex before to call service.RunCommand. NB2: I have no background with .net remoting, nor WCF which is recommended replacer. (I chose .net remoting because this looked easier to set-up for this single shot issue in running external commands).

• Boot custom linux up by pressing Lenovo OKR button?

  - by Semmu

  I have a Lenovo Y510p laptop and I'm a Linux user, use Windows only for gaming. The device had no OS when I bought it and I also installed an SSD besides the 1TB hard drive. I would like to "hack" the One-Key-Recovery button, because I have no interest in its default behaviour (I don't need Windows recovery), but if I could boot up a hidden, fail-safe Linux with it, that would be great. How could I achieve it? I tried to search what the button does, but I only found some installers for Windows that could magically create a partition for the recovery. I would like to override this behaviour completely to boot up something else.

• Android: Custom ListAdapter extending BaseAdapter crashes on application launch.

  Data being pulled from a local DB, then mapped using a cursor. Custom Adapter displays data similar to a ListView. As items are added/deleted from the DB, the adapter is supposed to refresh.

• How to configure custom binding to consume this WS secure Webservice using WCF?

  Hello all, I'm trying to configure a WCF client to be able to consume a webservice that returns the following response message: Response message <env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ns0="http://myservice.wsdl"> <env:Header> <wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" env:mustUnderstand="1" /> </env:Header> <env:Body> <ns0:StatusResponse> <result> ... </result> </ns0:StatusResponse> </env:Body> </env:Envelope> To do this, I've constructed a custom binding (which doesn't work).

• Why does my TextBox with custom control template not have a visible text cursor?

  - by Philipp Schmid

  I have a custom control template which is set via the style property on a TextBox. The visual poperties are set correctly, even typing to the textbox works, but there is no insertion cursor (the | symbol) visible which makes editing challenging for our users. How does the control template need changing to get the traditional TextBox behavior back? <Style x:Key="DemandEditStyle" TargetType="TextBox"> <EventSetter Event="LostFocus" Handler="DemandLostFocus" /> <Setter Property="HorizontalAlignment" Value="Stretch" /> <Setter Property="VerticalAlignment" Value="Stretch" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate> <Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> <Grid.ColumnDefinitions> <ColumnDefinition Width="*" /> <ColumnDefinition Width="1" /> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition Height="*" /> <RowDefinition Height="1" /> </Grid.RowDefinitions> <Grid.Background> <LinearGradientBrush StartPoint="0,0" EndPoint="0,1"> <GradientStop Color="White" Offset="0" /> <GradientStop Color="White" Offset="0.15" /> <GradientStop Color="#EEE" Offset="1" /> </LinearGradientBrush> </Grid.Background> <Border Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="2" Background="Black" /> <Border Grid.Row="0" Grid.Column="1" Grid.RowSpan="2" Background="Black" /> <Grid Grid.Row="0" Grid.Column="0" Margin="2"> <Grid.ColumnDefinitions> <ColumnDefinition Width="1" /> <ColumnDefinition Width="*" /> <ColumnDefinition Width="1" /> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition Height="1" /> <RowDefinition Height="*" /> <RowDefinition Height="1" /> </Grid.RowDefinitions> <Border Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="3" Background="Black" /> <Border Grid.Row="0" Grid.Column="0" Grid.RowSpan="3" Background="Black" /> <Border Grid.Row="2" Grid.Column="0" Grid.ColumnSpan="3" Background="#CCC" /> <Border Grid.Row="0" Grid.Column="2" Grid.RowSpan="3" Background="#CCC" /> <TextBlock Grid.Row="1" Grid.Column="1" TextAlignment="Right" HorizontalAlignment="Center" VerticalAlignment="Center" Padding="3 0 3 0" Background="Yellow" Text="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Text}" Width="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Grid}, AncestorLevel=1}, Path=ActualWidth}" /> </Grid> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style> Update: Replacing the inner-most TextBox with a ScrollViewer and naming it PART_ContentHost indeed shows the text insertion cursor. Trying to right-align the text in the TextBox by either setting the HorizontalContentAlignment in the Style or as a property on the ScrollViewer were unsuccessful. Suggestions?

It sticks for awhile, then it appears to reset to empty. I'm thinking I must have a conflict in the code below, but I can't quite figure it. I'm allowing the user to set a custom page title for posts as well as pages via a custom "post/page title input field). Can anyone see an obvious issue here that might be resetting the page title to blank? // =================== // = POST OPTION BOX = // =================== add_action('admin_menu', 'my_post_options_box'); function my_post_options_box() { if ( function_exists('add_meta_box') ) { //add_meta_box( $id, $title, $callback, $page, $context, $priority ); add_meta_box('post_header', 'Custom Post Header Code (optional)', 'custom_post_images', 'post', 'normal', 'low'); add_meta_box('post_title', 'Custom Post Title', 'custom_post_title', 'post', 'normal', 'high'); add_meta_box('post_title_page', 'Custom Post Title', 'custom_post_title', 'page', 'normal', 'high'); add_meta_box('postexcerpt', __('Excerpt'), 'post_excerpt_meta_box', 'page', 'normal', 'core'); add_meta_box('categorydiv', __('Page Options'), 'post_categories_meta_box', 'page', 'side', 'core'); } } //Adds the custom images box function custom_post_images() { global $post; ?> <div class="inside"> <textarea style="height:70px; width:100%;margin-left:-5px;" name="customHeader" id="customHeader"><?php echo get_post_meta($post->ID, 'customHeader', true); ?></textarea> <p>Enter your custom html code here for the post page header/image area.

• alot questings since i wanted to make a new SSB game or mario game(that use 3d models) [closed]

  - by user20465

  i have just started to study programming and i know already ppl will say why make a so big project like as a SSB game for a noob game development? cuz i always wanted a SSB engine like as Mugen is a fighter game engine but is not like as SSB´s gameplay + is not using 3d models too so i will call it SSBmugen(until i find a better title for it i got afew ideas for titles) also i wanted to make this game so it can use SSBbrawl files(models+animations mainly) the moveset+Stage coding files i wanted to redo cuz so anything can be possible like make a teleporter or a pipe teleporter(like as Super mario bros game) on a stag e or make some stuff there is impossible in SSBbrawl for moveset coding but is not in SSBmugen like make so a char. summon a Clone and the clone will do a attack and then is gone or some attacks/moves also i will make a moveset/stage Coding editor so it will be really easy to make moveset/stages coding for yours 3d models/animations moveset+stage Coding i mean: hitboxes/hurtboxes/moving Stuff/moving bones like cape or hair bones that is moving by wind effects or falling or other stuff like that/other stuff that needed to be coded i have planed to make a editor(for moveset/char. coding) or add the editor in brawlbox for my game so other ppl can easy make moveset/stages Coding to they´s models/animations so it will be easy so even kids can make a custom movesets/stages why using SSBbrawl files?: cuz ppl have made alot of models or textures/custom movesets/custom stages like goku/other anime/not brawl stuff for super smash bros brawl hacking(a.k.a modding) so ppl dont have to redo anything if they wanted to have the custom models or textures/custom movesets/custom stages from SSBbrawl to SSBmugen +there is the program named brawlbox that can open brawl files like model/animations and can edit models or animations and import models from 3ds max to be the right model format for SSBbrawl and i also wanted it so easy to add(a.k.a installer) Recolours or alt. models(like as oneslot doctor mario model over mario´s boneset) or textures/Movesets/new char. slots/new stages so easy so you only needing to download themplace them in right foldername them the right nameStart the gameRecolours or alt. models or textures/Movesets/new char. slots/new stages works an loading right so you wont needing to edit any files for add something so kids/not so smart ppl can easy use the mods other ppl is making/uploading for this game here is the file format i wanted to know if they can be readed/opened if making a game that use these files: .mld0(brawl model file) .chr0(model animation for moving/scale/rota the bones) .srt0(animations for texture like moving eyes or blinking) .vis0(Animations for get polygons to hide/show with visibilitybones on the model there is also some polygons there ) .brres(a file format where stuff like model files or textures or animations is inside) .pac(a file format where the .brres is inside to keep model+textures+model for the shadow in 1 file) .wav (for SoundFX effects or voices to char. or stages) i am sure that one is possible the .wav files is inside a other file format for brawl but that file can´t you add more .wav files inside only replace so i wanted the .wav files outside so its easy to add/replace/remove SoundFX effects or voices to char. or stages .brstm(brawl music file so the music is looped perfect so it loop in middel of the music and not start over again then the music is done) afew more file formats (mainly for the Graphics effects like fire/aura/hit effects if not needing to redo them)so only coding in the editor i will make is needed to be done for port a SSBB hack(a.k.a mod)(moveset/stage coding) to this game wanted the game to be able to load these files and load them right like if loading wait1.chr0(idle animation) it will also load at same time wait1.srt0/wait1.vis0 and all kinda of animations is inside the same .brres file i am needing since it to be able to load the file format i wanted cuz: -the animations can´t be converted to any other animation file format and i dont think ppl want to redo these animations(inc. me for Goku to SSBbrawl) -models can be converted but then they lose all the shader/materials stuff like a shine effect or lighting on the model -.brstm can be converted to .wav but then there will be no loop so i prefer it can load this file format too for the music to stage/menu -brawlbox is really easy to use for make animation for the char. and import models from 3ds max so even around "not too stupid" 10 year kids can make SSBB mods(not try to be rude but to say how easy it is) also i wanted the folder setup for characters/stages/moveset/other stuff to be like this: https://www.dropbox.com/s/2oolm5z5ri234tz/SSBmugen%20Folder%20setup.txt just uploaded a txt file since it is a wall of text and this post is already a wall of test so it easy to place stuff (if not i do a program for to that so it auto place the stuff on right place) not 100% sure what to use of game engine to make this possible but i got a dll file from that brawlbox program that can open/read/edit these file formats if that helps i also got open source of brawlbox i have kinda learned programming(since its kinda the same thing but still not 100% same) from Super smash bros modding/hacking like coding a moveset for the new animations/models + have readed alittle about it but i am soon starting for real to study it for ppl who is alittle confuse for what i am asking for here is the list: -what game engine should i use to make a SSB clone? but at same time to make all this stuff i just said possible so ppl can make they own mods and share them and use the already made mods from SSBbrawl? and easy to use aswell so noob programmors can use it? -where to learning programming on internet to be even more ready to make a game like this? and dont wanted to start in the small like making small boring 2d games that no one care about anyway ps. i am also planing a other project like as SSBmugen but it will be Super mario bros open (again tittle unsure but open means open source) i will make a Mario game engine that also use 3d models and can have 2d or 3d gameplay with any mario powerups/gameplay(from any mario platform games) there is ever made multiplayer like as in New super mario bros wii maybe multiplay over lan or online but for now over 1 PC also alittle planed for that to my SSBmugen a Level/world map editor for it too(easy to use so even kids can use it and make levels for it) so it just place the objects/enemies and options for them enemies since they are not 100% same AI in all mario game like to choose a goomba have AI from SM64 the Editor will be able to change the gameplay on a level while have a other gameplay on a other level like this: 1 level have Super mario bros 3 gameplay (then it will be a 3d model remake) a other level have super mario galaxy gameplay but in a Super mario 3d land level yet a other level have super mario 64 gameplay but with powerups from a other mario game like powerups from mario 3d land or can ride on Yoshi so you can easy remake your fav. level from a old mario game in this mario engine/editor or just make a custom one with yours fav. mario gameplay/powerups so it will be like turn off/on: walljump/triple jump/other kinda or jumps/2x punch and 1 kick+Air kick/SMG spin attack/Fludd/other stuff like that so you can make the gameplay from the first mario game to the newest or make custom gameplay on a level also the star(from 64/sunshine/galaxy) will be replaced with the flag from new super mario bros/mario 3d land since the game is not so much about getting stars its more about making/download the levels you wanted and share them to other ppl and play these level so after have killed like the boss from SM64 bomb omb field(if one have made that) you will get the flag instead of star since i wanted it to be simple to make levels in the editor to make the bosses/new enemies/new powerups/custom char. idk what to do to make that simple yet also thinking the mario game will use brawl files since it almost already got all needed animations/models for this since i dont wanted to redo animations/models and if needing more animations i can just make them easy in brawlbox since thats the program i am most used to make animations but that will be after my SSBmugen project if not this game will be easyer then SSBmugen to make since i am planing then 1 of them is done i use the that game as base to make the other (since both is kinda platfrom games and possible using same file format for both) also wanted to ask what is best to start with out of these 2 games? also will maybe make a DLC site(or ingame) for both of these games if they get done so it wont end up like as Mugen where you needing to look all over the internet to find the stuff you wanted but for my game all the mods for my game is on same place not sure about online mode for SSBmugen or super mario bros open but i can always add that then i get better at programming both games also need to have options on controls/if using joystick also that i have planed these game for a long time and got even more ideas for them but first i wanted to get them to work so i can add the other stuff later(like DLC or online mode or some other stuff later) right now i know 0,0001% to programming(in my option) maybe i know more then that since i have been study it alittle but i learning while making stuff like this that was also my plan for make these game learn while making them and get better to programming so again i say it i kinda dont want to hear dont do these projects cuz i already know it will be hard so dont wanted so much to heard stuff like: you can´t do it since you just started learning programming or this project will fail since somewhere i needing to get started with programming and this is where i want to start to make my dream games(possible other´s dream games too) and i dont think this project will fail if i work hard on it (as i possible will) and ppl will maybe help i think this was all my questing/ideas for now (sorry for it sounds more like ideas then questings) but i needing to say my ideas so you ppl can see what i needing to use for make this possible

• Adding <span> tags to all text nodes between custom self closing tags.

  - by Rachel

  I have a pair of custom self closing tags s1 and s2 defined in namespace x in my xhtml. For each tag pair s1, s2 having the same id, I want to add span tags to all the text nodes between them. Each s1, s2 tag pair have a unique id. The s1 tag has an attribute 'styleName' which needs to be copied as the class name for the span tags populated for the s1,s2 pair. Within a s1, s2 tag pair, other s1, s2 tags can occur. It is the id attribute of the tags s1 and s2 that help us to find the postion from where we need to start populating the span(for text nodes alone) and the end where we need to stop. In case of common text nodes that is part of the multiple s1, s2 pairs then the span tags needs to be opened and closed appropirately as shown in the sample below. I am not specific with the format of the id populated for the span tag. Along as it is unique it is fine. Can we achive this kind of a solution using XSL. I am using Saxon processor. Sample input: <html xmlns="http://www.w3.org/1999/xhtml" xmlns:x="http://sample.org"> <head> <title>This is my title</title> </head> <body> <h1 align="center">This <x:s1 id="1" styleName="name_1"/>is my <x:s2 id="1" />heading</h1> <p> Sample content <x:s1 id="2" styleName="name_2"/> Some text here. </p> <p> Here you <x:s2 id="2" />go. </p> <p> <x:s1 id="3" styleName="name_3"/>This <x:s1 id="4" styleName="name_4"/>is just a simple text <x:s2 id="4" />Some text here.<x:s2 id="3" /> Some content here. </p> <p> Use this <x:s1 id="5" styleName="name_5"/>space. </p> <p> Indroducing <x:s1 id="6" styleName="name_6"/> more information. </p> <p> Can add some <x:s2 id="6" />more content here. </p> <p> Sample content <x:s2 id="5" />Some text here.

• SSH new connection begins to hang (not reject or terminate) after a day or so on Ubuntu 13.04 server

  Recently we upgraded the server from 12.04 LTS server to 13.04. All was well, including after a reboot.

This now happens every single time. It is imperative that I get it sorted. The strange thing is that it behaves initially then starts to hang after several hours. I perused logs previously and nothing stood out. From the auth.log, I can see that it has allowed me in, but still I get nothing back on the client side: Sep 20 12:47:50 cbear sshd[25376]: Accepted publickey for tfergeson from 10.1.10.14 port 54631 ssh2 Sep 20 12:47:50 cbear sshd[25376]: pam_unix(sshd:session): session opened for user tfergeson by (uid=0) UPDATES: Still occurring even after setting UseDNS no and commenting out #session optional pam_mail.so standard noenv This does not appear to be a network/dns related issue, as all services running on the machine are as responsive and accessible as ever, with the exception of sshd. Any thoughts on where to start?
