• Tunnel is up but cannot ping directly connected network

  - by drmanalo

  We configured a site-to-site VPN and here is the topology. I control the network on the left but not the one on the right. All devices in our network has public IPs. Server---ASA5505---Cisco887======Internet=====ASA5510---devices I can see the tunnel is up and can do extended ping using a loopback interface. From the 10.175 and 10.165 networks, they can also ping my loopback address. I can also dial in using a Cisco VPN client, and can connect to the devices on the right. #show crypto session Crypto session current status Interface: Vlan3 Profile: xxx-profile Session status: UP-ACTIVE Peer: 213.121.x.x port 500 IKEv1 SA: local 77.245.x.x/500 remote 213.121.x.x/500 Active IPSEC FLOW: permit ip 10.0.20.0/255.255.255.240 10.175.0.0/255.255.128.0 Active SAs: 0, origin: crypto map IPSEC FLOW: permit ip 10.0.20.0/255.255.255.240 10.165.0.0/255.255.192.0 Active SAs: 2, origin: crypto map #ping 10.165.29.39 source loopback 2 Type escape sequence to abort.

• Linux: Apple Wireless A1314 Fn key not registered, looks like software bug

  - by ramplank

  I'm trying to set up my Apple Wireless Keyboard with my Kubuntu systems. These are PC hardware powered by Intel Atom and Intel i5 respectively. The keyboard has a US keyboard layout and has model number A1314 written on the back. It takes two AA batteries. I'm saying that because it appears there are multiple types of model A1314. I have tried this on a 10.04, 11.04, 11.10 and 12.04 system with no success. Every time using a bluetooth dongle and the KDE bluetooth notification tray applet, the keyboard can be connected. In both cases it shows up as "Apple Wireless Keyboard". Almost everything works as expected, in fact, I'm typing on it right now. But one thing doesn't: The Fn key. I'd like to use Fn + Down Arrow as PgDn / Page Down, I understand this is default behaviour on Apple keyboards. And of course I'd like the same for Page Up, Home and End. I'll stick to Page Down in my example. I used the xev tool to see the keycodes the system receives, and if I press on Fn nothing happens, and nothing is registered. If I press Fn + Down Arrow, xev only registers the down arrow. Here's the output from my 11.04 system to illustrate: Press just the Fn key: no output Press Down Arrow key: KeyPress event, serial 36, synthetic NO, window 0x4400001, root 0x15d, subw 0x4400002, time 2699773, (44,45), root:(1352,298), state 0x10, keycode 116 (keysym 0xff54, Down), same_screen YES, XLookupString gives 0 bytes: XmbLookupString gives 0 bytes: XFilterEvent returns: False KeyRelease event, serial 36, synthetic NO, window 0x4400001, root 0x15d, subw 0x4400002, time 2699860, (44,45), root:(1352,298), state 0x10, keycode 116 (keysym 0xff54, Down), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False Press Fn+Down Arrow Keys together: KeyPress event, serial 36, synthetic NO, window 0x4400001, root 0x15d, subw 0x4400002, time 2701548, (44,45), root:(1352,298), state 0x10, keycode 116 (keysym 0xff54, Down), same_screen YES, XLookupString gives 0 bytes: XmbLookupString gives 0 bytes: XFilterEvent returns: False KeyRelease event, serial 36, synthetic NO, window 0x4400001, root 0x15d, subw 0x4400002, time 2701623, (44,45), root:(1352,298), state 0x10, keycode 116 (keysym 0xff54, Down), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False I've been searching this forum and other Linux-related forums for hours but I still have not found a solution. I mostly found advice on how to fix this when using an actual apple laptop or desktop, but I don't have that. They said to try something like the following echo 2 > /sys/module/hid_apple/ ... But since there's no hid_apple directory present on my systems, I've needed to modprobe hid_apple first. That didn't help either. I'm cool with changing some config files, or compiling my own patched kernel if that's necessary. I currently have a 10.04 and 12.04 system available to test. The same issue occurs when hooked up to Windows 7. Fn key still does nothing, not by itself or in combination with other keys. With some AutoHotkey fiddling, I was able to confirm the key is registered as pressed, but ignored by default. A custom AutoHotkey script can fix that. But AutoHotkey is only for Windows, I want my problem fixed on Linux. Hooked up to an iPad 2 it only works in combination with the F1-F12 keys. Not with the arrow keys. If the screen of the ipad is off, and I press just the Fn key, the screen will come on, so the key itself is registered as pressed. So to sum up my question: Can anyone help me get Page Up, Page Down, Home and End to work on this keyboard, when that requires me to use an Fn key which is currently not registered?

  I wrote a CPU monitoring program in Python. For some reason sometimes the the program will run without any problem. Then other times the program won't even start because of the following error.

• Trying to create scrolling horizontal thumbnail navigation that hides on left side when not in use

  - by user346602

  Hi, I am trying recreate the following type of scrolling thumbnail navigation as described in the following tutorial: http://tympanus.net/codrops/2010/05/10/scrollable-thumbs-menu/ I require my thumbs to slide out horizontally from the left. I have amended the code to the best of my abilities, but I can't get it to work. (Think the problem is in the top third of the jquery). Here is what I have to date: HTML <ul class="menu" id="menu"> <li> <a href="#"></a> <div class="sc_menu_wrapper"> <div class="sc_menu"> <a href="#"><img src="images/gallery/1.jpg" alt=""/></a> <a href="#"><img src="images/gallery/2.jpg" alt=""/></a> <a href="#"><img src="images/gallery/3.jpg" alt=""/></a> <a href="#"><img src="images/gallery/4.jpg" alt=""/></a> <a href="#"><img src="images/gallery/5.jpg" alt=""/></a> </div> </div> </li> </ul> CSS /* Navigation Style */ ul.menu{ position: fixed; top: 0px; left:0px; width: 100%; } ul.menu li{ position:relative; width: 100% } ul.menu li > a{ position:absolute; top:300px; left:0px; width:40px; height:200px; background-color:#e7e7e8; } /* Thumb Scrolling Style */ div.sc_menu_wrapper { position: absolute; right: 0px; height: 220px; overflow: hidden; top: 300px; left:0px; visibility:hidden; } div.sc_menu { height: 200px; visibility:hidden; } .sc_menu a { display: block; background-color:#e7e7e8; } .sc_menu img { display: block; border: none; opacity:0.3; filter:progid:DXImageTransform.Microsoft.Alpha(opacity=30); } JQUERY $(function(){ // function to make the thumbs menu scrollable function buildThumbs($elem){ var $wrapper = $elem.next(); var $menu = $wrapper.find('.sc_menu'); var inactiveMargin = 220; // move the scroll down to the beggining (move as much as the height of the menu) $wrapper.scrollRight($menu.outerHeight()); //when moving the mouse up or down, the wrapper moves (scrolls) up or down $wrapper.bind('mousemove',function(e){ var wrapperWidth = $wrapper.width(); var menuWidth = $menu.outerWidth() + 2 * inactiveMargin; var top = (e.pageX - $wrapper.offset().right) * (menuWidth - wrapperWidth) / wrapperWidth - inactiveMargin; $wrapper.scrollRight(right+10); }); } var stacktime; $('#menu li > a').bind('mouseover',function () { var $this = $(this); buildThumbs($this); var pos = $this.next().find('a').size(); var f = function(){ if(pos==0) clearTimeout(stacktime); $this.next().find('a:nth-child('+pos+')').css('visibility','visible'); --pos; }; // each thumb will appear with a delay stacktime = setInterval(f , 50); }); /// on mouseleave of the whole <li> the scrollable area is hidden $('#menu li').bind('mouseleave',function () { var $this = $(this); clearTimeout(stacktime); $this.find('.sc_menu').css('visibility','hidden').find('a').css('visibility','hidden'); $this.find('.sc_menu_wrapper').css('visibility','hidden'); }); // when hovering a thumb, change its opacity $('.sc_menu a').hover( function () { var $this = $(this); $this.find('img') .stop() .animate({'opacity':'1.0'},400); }, function () { var $this = $(this); $this.find('img') .stop() .animate({'opacity':'0.3'},400); } ); }); Wondering if some eagle eye might be able to point out where I am going wrong. As my knowledge of JQuery is limited, I'm guessing it is in there. I really appreciate anyone taking the time to look this over. Thank you!

• How to patch an S4 method in an R package?

  - by Richie Cotton

  If you find a bug in a package, it's usually possible to patch the problem with fixInNamespace, e.g. fixInNamespace("mean.default", "base"). For S4 methods, I'm not sure how to do it though. The method I'm looking at is in the gWidgetstcltk package. You can see the source code with getMethod(".svalue", c("gTabletcltk", "guiWidgetsToolkittcltk")) I can't find the methods with fixInNamespace. fixInNamespace(".svalue", "gWidgetstcltk") Error in get(subx, envir = ns, inherits = FALSE) : object '.svalue' not found I thought setMethod might do the trick, but setMethod(".svalue", c("gTabletcltk", "guiWidgetsToolkittcltk"), definition = function (obj, toolkit, index = NULL, drop = NULL, ...) { widget = getWidget(obj) sel <- unlist(strsplit(tclvalue(tcl(widget, "selection")), " ")) if (length(sel) == 0) { return(NA) } theChildren <- .allChildren(widget) indices <- sapply(sel, function(i) match(i, theChildren)) inds <- which(visible(obj))[indices] if (!is.null(index) && index == TRUE) { return(inds) } if (missing(drop) || is.null(drop)) drop = TRUE chosencol <- tag(obj, "chosencol") if (drop) return(obj[inds, chosencol, drop = drop]) else return(obj[inds, ]) }, where = "package:gWidgetstcltk" ) Error in setMethod(".svalue", c("gTabletcltk", "guiWidgetsToolkittcltk"), : the environment "gWidgetstcltk" is locked; cannot assign methods for function ".svalue" Any ideas?

• Recursive code Sorting in VB

  - by Peter

  Ages old question: You have 2 hypothetical eggs, and a 100 story building to drop them from. The goal is to have the least number of guaranteed drops that will ensure you can find what floor the eggs break from the fall. You can only break 2 eggs. Using a 14 drop minimum method, I need help writing code that will allow me to calculate the following: Start with first drop attempt on 14th floor. If egg breaks then drop floors 1-13 to find the floor that causes break. ElseIf egg does not break then move up 13 floors to floor number 27 and drop again. If egg breaks then drop floors 15-26 starting on 15 working up to find the floor egg breaks on. ElseIf egg does not break then move up 12 floors to floor number 39 and drop again. etc. etc. The way this increases is as follows 14+13+12+11+10+9+8+7+6+5+4+3+2+1 So always adding to the previous value, by one less. I have never written a sorting algorithm before, and was curious how I might go about setting this up in a much more efficient way than a mile long of if then statements. My original idea was to store values for the floors in an array, and pull from that, using the index to move up or down and subtract or add to the variables. The most elegant solution would be a recursive function that handled this for any selected floor, 1-100, and ran the math, with an output that shows how many drops were needed in order to find that floor. Maximum is always 14, but some can be done in less.

• windows 7 randomly shuts down. where do I find related log? so that i can identify the error

  - by kirill_igum

  during the normal use, windows 7 shuts down. sometimes it happened when I start google chrome and few times during system update. after it shuts down, I turn it back on and I get to the screen, where windows asks me if I'd like a safe or normal start. the shutdown happens regardless if i'm on a battery or cord is there a log that can tell me where the error is? it can help me to further identify the solution. my setup: I run windows 7 on thinkpad x201 tablet. i have upgraded hard drive that worked fine for the last 6 months. the system is dual boot with ubuntu. I have installed some software recently, may be that can be the problem but sophos anti-virus cannot find anything. updates are all up to date.

• iptables issue on plesk

  - by Fred Rufin

  i don't know how to open a specific port (rtmp=1935) on my CentOS server using Plesk or itables. I created new rules for port 1935 i/o using Plesk/Modules/Firewall but this doesn't work. Nmap scanning tells me this : 1935/tcp filtered rtmp . So i decided to have look at my iptable using SSH (iptables -L), and iptables seems to contain my rules (tcp spt:macromedia-fcs): Chain INPUT (policy DROP) target prot opt source destination VZ_INPUT all -- anywhere anywhere ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED REJECT tcp -- anywhere anywhere tcp flags:!FIN,SYN,RST,ACK/SYN reject-with tcp-reset DROP all -- anywhere anywhere state INVALID ACCEPT all -- anywhere anywhere Chain FORWARD (policy DROP) target prot opt source destination VZ_FORWARD all -- anywhere anywhere ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED REJECT tcp -- anywhere anywhere tcp flags:!FIN,SYN,RST,ACK/SYN reject-with tcp-reset DROP all -- anywhere anywhere state INVALID ACCEPT all -- anywhere anywhere Chain OUTPUT (policy DROP) target prot opt source destination VZ_OUTPUT all -- anywhere anywhere ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED REJECT tcp -- anywhere anywhere tcp flags:!FIN,SYN,RST,ACK/SYN reject-with tcp-reset DROP all -- anywhere anywhere state INVALID ACCEPT all -- anywhere anywhere Chain VZ_FORWARD (1 references) target prot opt source destination Chain VZ_INPUT (1 references) target prot opt source destination ACCEPT tcp -- anywhere anywhere tcp dpt:http ACCEPT tcp -- anywhere anywhere tcp dpt:ssh ACCEPT tcp -- anywhere anywhere tcp dpt:smtp ACCEPT tcp -- anywhere anywhere tcp dpt:pop3 ACCEPT tcp -- anywhere anywhere tcp dpt:domain ACCEPT udp -- anywhere anywhere udp dpt:domain ACCEPT tcp -- anywhere anywhere tcp dpts:filenet-tms:65535 ACCEPT udp -- anywhere anywhere udp dpts:filenet-tms:65535 ACCEPT tcp -- anywhere anywhere tcp dpt:cddbp-alt ACCEPT tcp -- anywhere anywhere tcp dpt:pcsync-https ACCEPT tcp -- localhost.localdomain localhost.localdomain ACCEPT tcp -- anywhere anywhere tcp dpt:macromedia-fcs ACCEPT udp -- localhost.localdomain localhost.localdomain Chain VZ_OUTPUT (1 references) target prot opt source destination ACCEPT tcp -- anywhere anywhere tcp spt:http ACCEPT tcp -- anywhere anywhere tcp spt:ssh ACCEPT tcp -- anywhere anywhere tcp spt:smtp ACCEPT tcp -- anywhere anywhere tcp spt:pop3 ACCEPT tcp -- anywhere anywhere tcp spt:domain ACCEPT udp -- anywhere anywhere udp spt:domain ACCEPT tcp -- anywhere anywhere ACCEPT udp -- anywhere anywhere ACCEPT tcp -- anywhere anywhere tcp spt:cddbp-alt ACCEPT tcp -- anywhere anywhere tcp spt:pcsync-https ACCEPT tcp -- localhost.localdomain localhost.localdomain ACCEPT tcp -- anywhere anywhere tcp spt:macromedia-fcs ACCEPT udp -- localhost.localdomain localhost.localdomain My rules seems to be OK but there is no connection to 1935 port using a browser. I can connect to this port with SSH (typing "wget myServerIP:1935") but maybe this is because it is an SSH tunelling ? I don't know how to do.

• Secure iptables config for Samba

  - by Eric

  I'm trying to setup an iptables config such that outbound connections from my CentOS 6.2 server are allowed ONLY if they are of state ESTABLISHED. Currently, the following setup is working great for sshd, but all the Samba rules get totally ignored for a reason I cannot figure out. iptables Bash script to setup ALL rules: # Remove all existing rules iptables -F # Set default chain policies iptables -P INPUT DROP iptables -P FORWARD DROP iptables -P OUTPUT DROP # Allow incoming SSH iptables -A INPUT -i eth0 -p tcp --dport 22222 -m state --state NEW,ESTABLISHED -j ACCEPT iptables -A OUTPUT -o eth0 -p tcp --sport 22222 -m state --state ESTABLISHED -j ACCEPT # Allow incoming Samba iptables -A INPUT -i eth0 -s 10.1.1.0/24 -p udp --dport 137:138 -m state --state NEW,ESTABLISHED -j ACCEPT iptables -A OUTPUT -o eth0 -d 10.1.1.0/24 -p udp --sport 137:138 -m state --state ESTABLISHED -j ACCEPT iptables -A INPUT -i eth0 -s 10.1.1.0/24 -p tcp --dport 139 -m state --state NEW,ESTABLISHED -j ACCEPT iptables -A OUTPUT -o eth0 -d 10.1.1.0/24 -p tcp --sport 139 -m state --state ESTABLISHED -j ACCEPT # Enable these rules service iptables restart iptables rule list after running the above script: [root@repoman ~]# iptables -L Chain INPUT (policy DROP) target prot opt source destination ACCEPT tcp -- anywhere anywhere tcp dpt:22222 state NEW,ESTABLISHED Chain FORWARD (policy DROP) target prot opt source destination Chain OUTPUT (policy DROP) target prot opt source destination ACCEPT tcp -- anywhere anywhere tcp spt:22222 state ESTABLISHED Ultimately, I'm trying to restrict Samba the same way I have done for sshd. In addition, I'm trying to restrict connections to the following IP address range: 10.1.1.12 - 10.1.1.19 Can you guys offer some pointers or possibly even a full-blown solution? I've read man iptables quite extensively, so I'm not sure why the Samba rules are getting thrown out. Additionally, removing the -s 10.1.1.0/24 flags don't change the fact the rules get ignored.

• How to configure iptables to use apt-get in a server?

  - by segaco

  I'm starting using iptables (newbie) to protect a linux server (specifically Debian 5.0). Before I configure the iptables settings, I can use apt-get without a problem. But after I configure the iptables, the apt-get stop working. For example I use this script in iptables: #!/bin/sh IPT=/sbin/iptables ## FLUSH $IPT -F $IPT -X $IPT -t nat -F $IPT -t nat -X $IPT -t mangle -F $IPT -t mangle -X $IPT -P INPUT DROP $IPT -P OUTPUT DROP $IPT -P FORWARD DROP $IPT -A INPUT -i lo -j ACCEPT $IPT -A OUTPUT -o lo -j ACCEPT $IPT -A INPUT -p tcp --dport 22 -j ACCEPT $IPT -A OUTPUT -p tcp --sport 22 -j ACCEPT $IPT -A INPUT -p tcp --dport 80 -j ACCEPT $IPT -A OUTPUT -p tcp --sport 80 -j ACCEPT $IPT -A INPUT -p tcp --dport 443 -j ACCEPT $IPT -A OUTPUT -p tcp --sport 443 -j ACCEPT # Allow FTP connections @ port 21 $IPT -A INPUT -p tcp --sport 21 -m state --state ESTABLISHED -j ACCEPT $IPT -A OUTPUT -p tcp --dport 21 -m state --state NEW,ESTABLISHED -j ACCEPT # Allow Active FTP Connections $IPT -A INPUT -p tcp --sport 20 -m state --state ESTABLISHED,RELATED -j ACCEPT $IPT -A OUTPUT -p tcp --dport 20 -m state --state ESTABLISHED -j ACCEPT # Allow Passive FTP Connections $IPT -A INPUT -p tcp --sport 1024: --dport 1024: -m state --state ESTABLISHED -j ACCEPT $IPT -A OUTPUT -p tcp --sport 1024: --dport 1024: -m state --state ESTABLISHED,RELATED -j ACCEPT #DNS $IPT -A OUTPUT -p udp --dport 53 --sport 1024:65535 -j ACCEPT $IPT -A INPUT -p tcp --dport 1:1024 $IPT -A INPUT -p udp --dport 1:1024 $IPT -A INPUT -p tcp --dport 3306 -j DROP $IPT -A INPUT -p tcp --dport 10000 -j DROP $IPT -A INPUT -p udp --dport 10000 -j DROP then when I run apt-get I obtain: core:~# apt-get update 0% [Connecting to ftp.us.debian.org] [Connecting to security.debian.org] [Conne and it stalls.

• Game architecture: modeling different steps/types of UI

  - by Sander

  I have not done any large game development projects, only messed around with little toy projects. However, I never found an intuitive answer to a specific design question. Namely, how are different types/states of UI modeled in games? E.g. how is a menu represented? How is it different from a "game world" state (let's use an FPS as an example). How is an overlaid menu on top of a "game world" modeled? Let's imagine the main loop of a game. Where do the game states come into play? It it a simple case-by-case approach? if (menu.IsEnabled) menu.Process(elapsedTime); if (world.IsEnabled) world.Process(elapsedTime); if (menu.IsVisible) menu.Draw(); if (world.IsVisible) world.Draw(); Or are menu and world represented somewhere in a different logic layer and not represented at this level? (E.g. a menu is just another high-level entity like e.g. player input or enemy manager, equal to all others) foreach (var entity in game.HighLevelEntities) entity.Process(elapsedTime); foreach (var entity in game.HighLevelEntities) entity.Draw(elapsedTime); Are there well-known design patterns for this? Come to think of it, I don't know any game-specific design patterns - I assume there are others, as well? Please tell me about them.

• KnockoutJS - creating object doesn't work

  - by Kiwanax

  I'm doing a navigation list with menus and submenus. I have the following structure: function Menu(navigation) { this.NavigationUrl = ko.observable(navigation.NavigationUrl); this.NavigationTitle = ko.observable(navigation.NavigationTitle); this.NavigationDescription = ko.observable(navigation.NavigationDescription); var mappedChildren = ko.utils.arrayMap(navigation.Children, function (child) { return new Menu(child); }); this.Children = ko.observableArray(mappedChildren); } function DashboardViewModel() { var self = this; self.LoggedUser = ko.observable(""); self.Navigations = ko.observableArray([]); $.get('/Home/DashboardDependencies', {}, function (result) { self.LoggedUser(result.LoggedUser); var mappedNavigations = ko.utils.arrayMap(result.Navigations, function (item) { var menu = new Menu(item); // When I alert item, the result appears properly: // { "NavigationTitle": "blah", "NavigationDescription": "bleh" [...] } alert(JSON.stringify(item)); // But when I alert the new menu object, the result doesn't appear: // Just: "{}" alert(JSON.stringify(menu)); return menu; }); self.Navigations = mappedNavigations; }); } ko.applyBindings(new DashboardViewModel()); So, check it out. When I try to alert the item variable, the result appears properly. When I try to alert the new Menu object, the result just show {}. Why this' happening? Thank you all for the help!

• jquery animated buttons that just wont behave

  - by TJ Sherrill

  Ok I have a inline list of buttons. <ul id="nav"> <li class="home"><a href="#">Menu Item</a></li> <li class="contact"><a href="#">Menu Item</a></li> <li class="about"><a href="#">Menu Item</a></li> </ul> .home{ position:absolute; bottom:0; background-image:url(../img/menu/single_line.png); background-repeat:no-repeat; height:34px; width:134px; } .home_hover{ position:absolute; bottom:0; background-image:url(../img/menu/single_line_over.png); background-repeat:no-repeat; height:70px; width:134px; } $(document).ready(function(){ $("#nav .home").mouseover(function(){ $(this).toggleClass("home_hover").slideToggle("slow"); return false; }).mouseout(function(){ $(this).toggleClass("home_hover").slideToggle("slow"); return false; }); }); Each menu item has a background image, and then when its hovered the background image is replaced by a taller image. Ultimately I am trying to build a simple menu where on mouseover the menu item appears to slide up. But in reality Jquery can animate the toggleClass with slideToggle. The problem is that this current code doesn't behave right. It jumps up and down, because the text is moving. I am pretty new to Jquery so any help is greatly appreciated. I also loaded this up at http://gasworks.ravennainteractive.com/result/ thanks

• Jquery plugin seems to leak memory no matter what I do

  - by ddombrow

  I've recently been tasked with ferreting out some memory leaks in an application for my work. I've narrowed down one of the big leaks to a jquery plugin. It appears we're using a modified version of a popular context menu jquery plugin. It looks like one of the developers before me attempted to add a destroy method. I noticed it wasn't very well written and attempted to rewrite. Here's the meat of my destroy method: if (menu.childMenus) { for (var i = 0; i < menu.childMenus.length; i++) { $(menu.childMenus[i]).destroy(menu.childMenus[i], 'contextmenu'); } } var recursiveUnbind = function(node) { $(node).unbind(); //$(node).empty().remove(); $.each(node, function(obj) { recursiveUnbind(obj); }); }; $.each(menu, function() { recursiveUnbind(menu); }); $(menu).empty().remove(); In my mind this code should blow away all the jquery event binding and remove the dom elements, yet still the plugin leaks gobs of memory in IE7. The modified plugin with a test page can be found here: http://www.olduglyhead.com/jquery/leaks/ Clicking the button repeatedly will cause IE7 to leak a bunch of memory.

• Unordered list appears higher than div

  - by LordArmadillo

  I am trying to create a simple page, which I normally can without any trouble. However, the unordered list appears higher up the page than the div. I do know a solution for this, however I cannot remember it. The page goes like this: <style> ul.menu { list-style-type: none; margin:150; margin-bottom:30px; padding:0; display: block; width: 708px; margin-left: auto; margin-right: auto; } li.menu { float:left; display: block; width: 118px; } a.menu:link,a.menu:visited { color:black; display:block; border:1px solid black; background-color:#FFFF00; width:118px; text-align:center; text-decoration:none; font-family:"Courier New", Courier, monospace } a.menu:hover { background-color:#FFBB11; } </style> <div id="head"> My images here & such</div> <ul class="menu"> <li class="menu"> <a class="menu">Main</a> </li> </ul> Normally I welcome suggestions to change my code, but I have a deadline today! So, quick & simple help would be appreciated! Thanks! LordArmadillo

• Alert visualization recipe: Get out your blender, drop in some sp_send_dbmail, Google Charts API, add your favorite colors and sprinkle with html. Blend till it’s smooth and looks pretty enough to taste.

  - by Maria Zakourdaev

    I really like database monitoring. My email inbox have a constant flow of different types of alerts coming from our production servers with all kinds of information, sometimes more useful and sometimes less useful. Usually database alerts look really simple, it’s usually a plain text email saying “Prod1 Database data file on Server X is 80% used. You’d better grow it manually before some query triggers the AutoGrowth process”. Imagine you could have received email like the one below.  In addition to the alert description it could have also included the the database file growth chart over the past 6 months. Wouldn’t it give you much more information whether the data growth is natural or extreme? That’s truly what data visualization is for. Believe it or not, I have sent the graph below from SQL Server stored procedure without buying any additional data monitoring/visualization tool.   Would you like to visualize your database alerts like I do? Then like myself, you’d love the Google Charts. All you need to know is a little HTML and have a mail profile configured on your SQL Server instance regardless of the SQL Server version. First of all, I hope you know that the sp_send_dbmail procedure has a great parameter @body_format = ‘HTML’, which allows us to send rich and colorful messages instead of boring black and white ones. All that we need is to dynamically create HTML code. This is how, for instance, you can create a table and populate it with some data: DECLARE @html varchar(max) SET @html = '<html>' + '<H3><font id="Text" style='color: Green;'>Top Databases: </H3>' + '<table border="1" bordercolor="#3300FF" style='background-color:#DDF8CC' width='70%' cellpadding='3' cellspacing='3'>' + '<tr><font color="Green"><th>Database Name</th><th>Size</th><th>Physical Name</th></tr>' + CAST( (SELECT TOP 10                             td = name,'',                             td = size * 8/1024 ,'',                             td = physical_name              FROM sys.master_files               ORDER BY size DESC             FOR XML PATH ('tr'),TYPE ) AS VARCHAR(MAX)) + '</table>' EXEC msdb.dbo.sp_send_dbmail @recipients = '[email protected]', @subject ='Top databases', @body = @html, @body_format = 'HTML' This is the result:   If you want to add more visualization effects, you can use Google Charts Tools https://google-developers.appspot.com/chart/interactive/docs/index which is a free and rich library of data visualization charts, they’re also easy to populate and embed. There are two versions of the Google Charts Image based charts: https://google-developers.appspot.com/chart/image/docs/gallery/chart_gall This is an old version, it’s officially deprecated although it will be up for a next few years or so. I really enjoy using this one because it can be viewed within the email body. For mobile devices you need to change the “Load remote images” property in your email application configuration.           Charts based on JavaScript classes: https://google-developers.appspot.com/chart/interactive/docs/gallery This API is newer, with rich and highly interactive charts, and it’s much more easier to understand and configure. The only downside of it is that they cannot be viewed within the email body. Outlook, Gmail and many other email clients, as part of their security policy, do not run any JavaScript that’s placed within the email body. However, you can still enjoy this API by sending the report as an email attachment.

• Chrome and Firefox not able to find some sites after Ubuntu's recent update?

  - by gkr

  Loading of revision3.com in Chrome stops and status saying "waiting for static.inplay.tubemogul.com" grooveshark.com in Chrome never loads But wikipedia.org, google.com works just normal same behavior in Firefox too. I use wired DSL connection in Ubuntu 12.04. I guess this started happening after I upgraded the Chrome browser or Flash plugin few days ago from Ubuntu updates through update-manager.

• How to begin? Windows 8 Development

  - by Dennis Vroegop

  Ok. I convinced you in my last post to do some Win8 development. You want a piece of that cake, or whatever your reasons may be. Good! Welcome to the club! Now let me ask you a question: what are you going to write? Ah. That’s the big one, isn’t it? What indeed? If you have been creating applications for computers before you’re in for quite a shock. The way people perceive apps on a tablet is quite different from what we know as applications. There’s a reason we call them apps instead of applications! Yes, technically they are applications but we don’t call them apps only because it sounds cool. The abbreviated form of the word applications itself is a pointer. Apps are small. Apps are focused. Apps are more lightweight. Apps do one thing but they do that one thing extremely good. In the ‘old’ days we wrote huge systems. We build ecosystems of services, screens, databases and more to create a system that provides value for the user. Think about it: what application do you use most at work? Can you in one sentence describe what it is, or what it does and yet still distinctively describe its purpose? I doubt you can. Let’s have a look at Outlouk. We all know it and we all love or hate it. But what is it? A mail program? No, there’s so much more there: calendar, contacts, RSS feeds and so on. Some call it a ‘collaboration’  application but that’s not really true as well. After all, why should a collaboration application give me my schedule for the day? I think the best way to describe Outlook is “client for Exchange”  although that isn’t accurate either. Anyway: Outlook is a great application but it’s not an ‘app’ and therefor not very suitable for WinRT. Ok. Disclaimer here: yes, you can write big applications for WinRT. Some will. But that’s not what 99.9% of the developers will do. So I am stating here that big applications are not meant for WinRT. If 0.01% of the developers think that this is nonsense then they are welcome to go ahead but for the majority here this is not what we’re talking about. So: Apps are small, lightweight and good at what they do but only at that. If you’re a Phone developer you already know that: Phone apps on any platform fit the description I have above. If you’ve ever worked in a large cooperation before you might have seen one of these before: the Mission Statement. It’s supposed to be a oneliner that sums up what the company is supposed to do. Funny enough: although this doesn’t work for large companies it does work for defining your app. A mission statement for an app describes what it does. If it doesn’t fit in the mission statement then your app is going to get to big and will fail. A statement like this should be in the following style “<your app name> is the best app to <describe single task>” Fill in the blanks, write it and go! Mmm.. not really. There are some things there we need to think about. But the statement is a very, very important one. If you cannot fit your app in that line you’re preparing to fail. Your app will become to big, its purpose will be unclear and it will be hard to use. People won’t download it and those who do will give it a bad rating therefor preventing that huge success you’ve been dreaming about. Stick to the statement! Ok, let’s give it a try: “PlanesAreCool” is the best app to do planespotting in the field. You might have seen these people along runways of airports: taking photographs of airplanes and noting down their numbers and arrival- and departure times. We are going to help them out with our great app! If you look at the statement, can you guess what it does? I bet you can. If you find out it isn’t clear enough of if it’s too broad, refine it. This is probably the most important step in the development of your app so give it enough time! So. We’ve got the statement. Print it out, stick it to the wall and look at it. What does it tell you? If you see this, what do you think the app does? Write that down. Sit down with some friends and talk about it. What do they expect from an app like this? Write that down as well. Brainstorm. Make a list of features. This is mine: Note planes Look up aircraft carriers Add pictures of that plane Look up airfields Notify friends of new spots Look up details of a type of plane Plot a graph with arrival and departure times Share new spots on social media Look up history of a particular aircraft Compare your spots with friends Write down arrival times Write down departure times Write down wind conditions Write down the runway they take Look up weather conditions for next spotting day Invite friends to join you for a day of spotting. Now, I must make it clear that I am not a planespotter nor do I know what one does. So if the above list makes no sense, I apologize. There is a lesson: write apps for stuff you know about…. First of all, let’s look at our statement and then go through the list of features. Remove everything that has nothing to do with that statement! If you end up with an empty list, try again with both steps. Note planes Look up aircraft carriers Add pictures of that plane Look up airfields Notify friends of new spots Look up details of a type of plane Plot a graph with arrival and departure times Share new spots on social media Look up history of a particular aircraft Compare your spots with friends Write down arrival times Write down departure times Write down wind conditions Write down the runway they take Look up weather conditions for next spotting day Invite friends to join you for a day of spotting. That's better. The things I removed could be pretty useful to a plane spotter and could be fun to write. But do they match the statement? I said that the app is for spotting in the field, so “look up airfields” doesn’t belong there: I know where I am so why look it up? And the same goes for inviting friends or looking up the weather conditions for tomorrow. I am at the airfield right now, looking through my binoculars at the planes. I know the weather now and I don’t care about tomorrow. If you feel the items you’ve crossed out are valuable, then why not write another app? One that says “SpotNoter” is the best app for preparing a day of spotting with my friends. That’s a different app! Remember: Win8 apps are small and very good at doing ONE thing, and one thing only! If you have made that list, it’s time to prepare the navigation of your app. The navigation is how users see your app and how they use it. We’ll do that next time!

• Does anyone have database, programming language/framework suggestions for a GUI point of sale system

  - by Jason Down

  Our company has a point of sale system with many extras, such as ordering and receiving functionality, sales and order history etc. Our main issue is that the system was not designed properly from the ground up, so it takes too long to make fixes and handle requests from our customers. Also, the current technology we are using (Progress database, Progress 4GL for the language) incurs quite a bit of licensing expenses on our customers due to mutli-user license fees for database connections etc. After a lot of discussion it is looking like we will probably start over from scratch (while maintaining the current product at least for the time being). We are looking for a couple of things: Create the system with a nice GUI front end (it is currently CHUI and the application was not built in a way that allows us to redesign the front end... no layering or separation of business logic and gui...shudder). Create the system with the ability to modularize different functionality so the product doesn't have to include all features. This would keep the cost down for our current customers that want basic functionality and a lower price tag. The bells and whistles would be available for those that would want them. Use proper design patterns to make the product easy to add or change any part at any time (i.e. change the database or change the front end without needing to rewrite the application or most of it). This is a problem today because the Progress 4GL code is directly compiled against the database. Small changes in the database requires lots of code recompiling. Our new system will be Linux based, with a possibility of a client application providing functionality from one or more windows boxes. So what I'm looking for is any suggestions on which database and/or framework or programming language(s) someone might recommend for this sort of product. Anyone that has experience in this field might be able to point us in the right direction or even have some ideas of what to avoid. We have considered .NET and SQL Express (we don't need an enterprise level DB), but that would limit us to windows (as far as I know anyway). I have heard of Mono for writing .NET code in a Linux environment, but I don't know much about it yet. We've also considered a Java and MySql based implementation. To summarize we are looking to do the following: Keep licensing costs down on the technology we will use to develop the product (Oracle, yikes! MySQL, nice.) Deliver a solution that is easily maintainable and supportable. A solution that has a component capable of running on "old" hardware through a CHUI front end. (some of our customers have 40+ terminals which would be a ton of cash in order to convert over to a PC). Suggestions would be appreciated. Thanks [UPDATE] I should note that we are currently performing a total cost analysis. This question is intended to give us a couple of "educated" options to look into to include in or analysis. Anyone who could share experiences/suggestions about client/server setups would be appreciated (not just those who have experience with point of sale systems... that would just be a bonus).

• Common Live Upgrade problems

  - by user12611829

  As I have worked with customers deploying Live Upgrade in their environments, several problems seem to surface over and over. With this blog article, I will try to collect these troubles, as well as suggest some workarounds. If this sounds like the beginnings of a Wiki, you would be right. At present, there is not enough material for one, so we will use this blog for the time being. I do expect new material to be posted on occasion, so if you wish to bookmark it for future reference, a permanent link can be found here. Live Upgrade copies over ZFS root clone This was introduced in Solaris 10 10/09 (u8) and the root of the problem is a duplicate entry in the source boot environments ICF configuration file. Prior to u8, a ZFS root file system was not included in /etc/vfstab, since the mount is implicit at boot time. Starting with u8, the root file system is included in /etc/vfstab, and when the boot environment is scanned to create the ICF file, a duplicate entry is recorded. Here's what the error looks like. # lucreate -n s10u9-baseline Checking GRUB menu... System has findroot enabled GRUB Analyzing system configuration. Comparing source boot environment file systems with the file system(s) you specified for the new boot environment. Determining which file systems should be in the new boot environment. Updating boot environment description database on all BEs. Updating system configuration files. Creating configuration for boot environment . Source boot environment is . Creating boot environment . Creating file systems on boot environment . Creating file system for in zone on . The error indicator ----- /usr/lib/lu/lumkfs: test: unknown operator zfs Populating file systems on boot environment . Checking selection integrity. Integrity check OK. Populating contents of mount point . This should not happen ------ Copying. Ctrl-C and cleanup If you weren't paying close attention, you might not even know this is an error. The symptoms are lucreate times that are way too long due to the extraneous copy, or the one that alerted me to the problem, the root file system is filling up - again thanks to a redundant copy. This problem has already been identified and corrected, and a patch (121431-58 or later for x86, 121430-57 for SPARC) is available. Unfortunately, this patch has not yet made it into the Solaris 10 Recommended Patch Cluster. Applying the prerequisite patches from the latest cluster is a recommendation from the Live Upgrade Survival Guide blog, so an additional step will be required until the patch is included. Let's see how this works. # patchadd -p | grep 121431 Patch: 121429-13 Obsoletes: Requires: 120236-01 121431-16 Incompatibles: Packages: SUNWluzone Patch: 121431-54 Obsoletes: 121436-05 121438-02 Requires: Incompatibles: Packages: SUNWlucfg SUNWluu SUNWlur # unzip 121431-58 # patchadd 121431-58 Validating patches...

This time it took just a few seconds. A cursory examination of the offending ICF file (/etc/lu/ICF.3 in this case) shows that the duplicate root file system entry is now gone. # cat /etc/lu/ICF.3 s10u8-baseline:-:/dev/zvol/dsk/panroot/swap:swap:8388608 s10u8-baseline:/:panroot/ROOT/s10u8-baseline:zfs:0 s10u8-baseline:/vbox:pandora/vbox:zfs:0 s10u8-baseline:/setup:pandora/setup:zfs:0 s10u8-baseline:/export:pandora/export:zfs:0 s10u8-baseline:/pandora:pandora:zfs:0 s10u8-baseline:/panroot:panroot:zfs:0 s10u8-baseline:/workshop:pandora/workshop:zfs:0 s10u8-baseline:/export/iso:pandora/iso:zfs:0 s10u8-baseline:/export/home:pandora/home:zfs:0 s10u8-baseline:/vbox/HardDisks:pandora/vbox/HardDisks:zfs:0 s10u8-baseline:/vbox/HardDisks/WinXP:pandora/vbox/HardDisks/WinXP:zfs:0 Solaris 10 9/10 introduces new autoregistration file This one is actually mentioned in the Oracle Solaris 9/10 release notes. I know, I hate it when that happens too. Here's what the "error" looks like. # luupgrade -u -s /mnt -n s10u9-baseline System has findroot enabled GRUB No entry for BE in GRUB menu Copying failsafe kernel from media. 61364 blocks miniroot filesystem is Mounting miniroot at ERROR: The auto registration file does not exist or incomplete. The auto registration file is mandatory for this upgrade. Use -k argument along with luupgrade command. autoreg_file is path to auto registration information file. See sysidcfg(4) for a list of valid keywords for use in this file. The format of the file is as follows. oracle_user=xxxx oracle_pw=xxxx http_proxy_host=xxxx http_proxy_port=xxxx http_proxy_user=xxxx http_proxy_pw=xxxx For more details refer "Oracle Solaris 10 9/10 Installation Guide: Planning for Installation and Upgrade". As with the previous problem, this is also easy to work around. Assuming that you don't want to use the auto-registration feature at upgrade time, create a file that contains just autoreg=disable and pass the filename on to luupgrade. Here is an example. # echo "autoreg=disable" /var/tmp/no-autoreg # luupgrade -u -s /mnt -k /var/tmp/no-autoreg -n s10u9-baseline System has findroot enabled GRUB No entry for BE in GRUB menu Copying failsafe kernel from media. 61364 blocks miniroot filesystem is Mounting miniroot at ####################################################################### NOTE: To improve products and services, Oracle Solaris communicates configuration data to Oracle after rebooting. You can register your version of Oracle Solaris to capture this data for your use, or the data is sent anonymously. For information about what configuration data is communicated and how to control this facility, see the Release Notes or www.oracle.com/goto/solarisautoreg.

CAUTION: Interrupting this process may leave the boot environment unstable or unbootable. The Live Upgrade operation now proceeds as expected. Once the system upgrade is complete, we can manually register the system. If you want to do a hands off registration during the upgrade, see the Oracle Solaris Auto Registration section of the Oracle Solaris Release Notes for instructions on how to do that.
