Why has wireless disappeared after my 12.10 upgrade?

- by Shay Guy

I just upgraded to 12.10 on my Lenovo B570 laptop. NetworkManager isn't displaying a submenu for wireless connections at all, even though I downloaded the update through the wireless connection. This displeases me. Stuff I've tried includes: $ sudo modprobe wl FATAL: Module wl not found. $ sudo lspci -nn | grep "BCM" 02:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01) $ rfkill list all 0: ideapad_wlan: Wireless LAN Soft blocked: no Hard blocked: no ETA: linux-headers-generic is already the newest version, and what I get when reinstalling bcmwl-kernel-source includes the following, near the end. DKMS: install completed.

Building an ASP.Net 4.5 Web forms application - part 4

- by nikolaosk

?his is the fourth post in a series of posts on how to design and implement an ASP.Net 4.5 Web Forms store that sells posters on line.There are 3 more posts in this series of posts.Please make sure you read them first.You can find the first post here. You can find the second post here. You can find the third post here. In this new post we will build on the previous posts and we will demonstrate how to display the posters per category.We will add a ListView control on the PosterList.aspx and will bind data from the database. We will use the various templates.Then we will write code in the PosterList.aspx.cs to fetch data from the database.1) Launch Visual Studio and open your solution where your project lives2) Open the PosterList.aspx page. We will add some markup in this page. Have a look at the code below <section class="posters-featured"> <ul> <asp:ListView ID="posterList" runat="server" DataKeyNames="PosterID" GroupItemCount="3" ItemType="PostersOnLine.DAL.Poster" SelectMethod="GetPosters"> <EmptyDataTemplate> <table id="Table1" runat="server"> <tr> <td>We have no data.</td> </tr> </table> </EmptyDataTemplate> <EmptyItemTemplate> <td id="Td1" runat="server" /> </EmptyItemTemplate> <GroupTemplate> <tr ID="itemPlaceholderContainer" runat="server"> <td ID="itemPlaceholder" runat="server"></td> </tr> </GroupTemplate> <ItemTemplate> <td id="Td2" runat="server"> <table> <tr> <td> </td> <td> <a href="PosterDetails.aspx?posterID=<%#:Item.PosterID%>"> <img src="<%#:Item.PosterImgpath%>" width="100" height="75" border="1"/></a> </td> <td> <a href="PosterDetails.aspx?posterID=<%#:Item.PosterID%>"> <span class="PosterName"> <%#:Item.PosterName%> </span> </a> <br /> <span class="PosterPrice"> <b>Price: </b><%#:String.Format("{0:c}", Item.PosterPrice)%> </span> <br /> </td> </tr> </table> </td> </ItemTemplate> <LayoutTemplate> <table id="Table2" runat="server"> <tr id="Tr1" runat="server"> <td id="Td3" runat="server"> <table ID="groupPlaceholderContainer" runat="server"> <tr ID="groupPlaceholder" runat="server"></tr> </table> </td> </tr> <tr id="Tr2" runat="server"><td id="Td4" runat="server"></td></tr> </table> </LayoutTemplate> </asp:ListView> </ul> </section> 3) We have a ListView control on the page called PosterList. I set the ItemType property to the Poster class and then the SelectMethod to the GetPosters method. I will create this method later on. (ItemType="PostersOnLine.DAL.Poster" SelectMethod="GetPosters")Then in the code below I have the data-binding expression Item available and the control becomes strongly typed.So when the user clicks on the link of the poster's category the relevant information will be displayed (photo,name and price) <td> <a href="PosterDetails.aspx?posterID=<%#:Item.PosterID%>"> <img src="<%#:Item.PosterImgpath%>" width="100" height="75" border="1"/></a> </td>4) Now we need to write the simple method to populate the ListView control.It is called GetPosters method.The code follows public IQueryable<Poster> GetPosters([QueryString("id")] int? PosterCatID) { PosterContext ctx = new PosterContext(); IQueryable<Poster> query = ctx.Posters; if (PosterCatID.HasValue && PosterCatID > 0) { query = query.Where(p=>p.PosterCategoryID==PosterCatID); } return query; } This is a very simple method that returns information about posters related to the PosterCatID passed to it.I bind the value from the query string to the PosterCatID parameter at run time.This is all possible due to the QueryStringAttribute class that lives inside the System.Web.ModelBinding and gets the value of the query string variable id.5) I run my application and then click on the "Midfilders" link. Have a look at the picture below to see the results. In the Site.css file I added some new CSS rules to make everything more presentable. .posters-featured { width:840px; background-color:#efefef;}.posters-featured a:link, a:visited, a:active, a:hover { color: #000033; }.posters-featured a:hover { background-color: #85c465; } 6) I run the application again and this time I do not choose any category, I simply navigate to the PosterList.aspx page. I see all the posters since no query string was passed as a parameter.Have a look at the picture below ?ake sure you place breakpoints in the code so you can see what is really going on.In the next post I will show you how to display poster details.Hope it helps!!!

How to solve: "Connect to host some_hostname port 22: Connection timed out"

- by Aufwind

I have two Ubuntu machines. Both have openssh-client and openssh-server installed on them. ssh-ing from machine G (fresh Ubuntu 11.10 installation) to machine K works great. But ssh-ing from machine K to machine G results always in the Error: Connect to host some_hostname port 22: Connection timed out I went through the troubleshooting section of help.ubuntu.com and I got the following results: ps -A | grep sshd # results in 848 ? 00:00:00 sshd - sudo ss -lnp | grep sshd # results in 0 128 :::22 :::* users:(("sshd",848,4)) 0 128 *:22 *:* users:(("sshd",848,3)) - ssh -v localhost # works! - sudo ufw status verbose # yields: "Status: inactive" I haven't change anything in the config file. What can I do to locate the Problem and solve it? Glad about every hint! Edit: ping was succesful in both directions! I did a telnet <machineK> 22 from machin G which resulted in Trying and then in telnet: Unable to connect to remote host: Connection timed out. But telnet the other way around worked just fine! Edit 2: ssh start/running, process 966 # yields: ssh start/running, process 966 /etc/hostname # contains my hostname, let's call it blubb /etc/hosts # contains the following 127.0.0.1 localhost # 127.0.1.1 blubb 129.26.68.74 blubb # I added this! - sudo service ufw status # yields: ufw start/running I installed Gufw and set it to ON. Then I selected from Incoming the option ALLOW. Then I sshed to another machine from where I sshed back to my machine. Still the same error as above: connect to host blubb port 22: Connection timed out Any more hints, what I can check?

update-apt-xapian-index hogs CPU, even when Update Manager is set to not check for updates

- by Dave M G

I have a slightly older laptop running Ubuntu 11.10. It runs fine, but frequently, when I start it up, the CPU monitor in my Gnome Panel shows 100% usage for for what can be up to five minutes or so. It seems that the offending process is update-apt-xapian-index, which, if I understand correctly, is the update manager checking for updates. I have gone into the update manager settings, and selected to never check for updates. I'll do that manually when I feel like I have the time to leave the laptop running for that. However, despite my selection, this still happens. Roughly 50% of the time or more, when I start my laptop, it runs update-apt-xapian-index. How can I get the update manager to respect my settings, or at least to get this process to stop eating my CPU cycles?

Restrictive routing best practices for Google App Engine with python?

- by Aleksandr Makov

Say I have a simple structure: app = webapp2.WSGIApplication([ (r'/', 'pages.login'), (r'/profile', 'pages.profile'), (r'/dashboard', 'pages.dash'), ], debug=True) Basically all pages require authentication except for the login. If visitor tries to reach a restrictive page and he isn't authorized (or lacks privileges) then he gets redirected to the login view. The question is about the routing design. Should I check the auth and ACL privs in each of the modules (pages.profile and pages.dash from example above), or just pass all requests through the single routing mechanism: app = webapp2.WSGIApplication([ (r'/', 'pages.login'), (r'/.+', 'router') ], debug=True) I'm still quite new to the GAE, but my app requires authentication as well as ACL. I'm aware that there's login directive on the server config level, but I don't know how it works and how I can tight it with my ACL logic and what's worse I cannot estimate time needed to get it running. Besides, it looks only to provide only 2 user groups: admin and user. In any case, that's the configuration I use: handlers: - url: /favicon.ico static_files: static/favicon.ico upload: static/favicon.ico - url: /static/* static_dir: static - url: .* script: main.app secure: always Or I miss something here and ACL can be set in the config file? Thanks.

How can i change focus when game locks it?

- by GrizzLy

I am playing wolfenstein:enemy territory, and if i play it in windowed mode, i can't change focus from game to something else (alt+tab doesnt work). EDIT1: As far as i could try, only ctrl+alt+Fx works (x is one number, for example F1 will switch to terminal). Could i somehow capture this kind of shortcut somewhere on X level and then send it to compiz to change focus (minimize currently focused window)? EDIT2: I found one other way, it works for Wolf:ET, it may help with other games too, if you turn on gameconsole (usually tilde key) game will release mouse lock (in windowed mode).

Compizconfig Grid doesn't work under Ubuntu as virtual machine

- by SoftTimur

I have installed Ubuntu as virtual machine within Mac. I have installed VM tools. The approach in this link of Compizconfig Grid, which worked in my previous laptop where Ubuntu was not a virtual machine, does not work anymore. I set some shortcut, but no action is launched... Does anyone know why? The major functionality I need from Grid is tiling windows to left/right side of the screen... Does anyone know any alternative?

mount remotely mybook live network drive

- by bob

I have a mybook live western digital 1TB hard disk connected to fritzbox 7270 router in office. When I am in the office, I can mount this drive to ubuntu since I have added to the etc/fstab file: //192.168.178.30/user /home/user/DISK cifs auto,iocharset=utf8,user=user%password 0 0 Is there a similar, easy & safe way, to do the same when I am out of the office using the static IP of the fritzbox router? I have already added tcp port forwarding in the router for ports 8080 (to 80 of the disk) and 8443 (to 443 of the disk). Thank you in advance

How can I restore a country specific apt-get update mirror?

- by ferrarimarco

While configuring my new 13.10 installation, I chose to change the default update server using the "Software & Updates" GUI tool available in the System settings panel. Before this change the selected update server was "Server for Italy" (I live there). Now it's one of the mirrors available in the list of mirrors (one of italian ones). How is "Server for COUNTRY" chosen in the list of mirrors for a country? How can I restore the "Server for Italy" option? Is it advisable to do so? I want to revert that setting because I found that the selected mirror is not up to date (checked from Here).

Building an ASP.Net 4.5 Web forms application - part 5

- by nikolaosk

?his is the fifth post in a series of posts on how to design and implement an ASP.Net 4.5 Web Forms store that sells posters on line. There are 4 more posts in this series of posts.Please make sure you read them first.You can find the first post here. You can find the second post here. You can find the third post here.You can find the fourth here. In this new post we will build on the previous posts and we will demonstrate how to display the details of a poster when the user clicks on an individual poster photo/link. We will add a FormView control on a web form and will bind data from the database. FormView is a great web server control for displaying the details of a single record. 1) Launch Visual Studio and open your solution where your project lives2) Add a new web form item on the project.Make sure you include the Master Page.Name it PosterDetails.aspx 3) Open the PosterDetails.aspx page. We will add some markup in this page. Have a look at the code below <asp:Content ID="Content2" ContentPlaceHolderID="FeaturedContent" runat="server"> <asp:FormView ID="posterDetails" runat="server" ItemType="PostersOnLine.DAL.Poster" SelectMethod ="GetPosterDetails"> <ItemTemplate> <div> <h1><%#:Item.PosterName %></h1> </div> <br /> <table> <tr> <td> <img src="<%#:Item.PosterImgpath %>" border="1" alt="<%#:Item.PosterName %>" height="300" /> </td> <td style="vertical-align: top"> <b>Description:</b><br /><%#:Item.PosterDescription %> <br /> <span><b>Price:</b> <%#: String.Format("{0:c}", Item.PosterPrice) %></span> <br /> <span><b>Poster Number:</b> <%#:Item.PosterID %></span> <br /> </td> </tr> </table> </ItemTemplate> </asp:FormView></asp:Content> I set the ItemType property to the Poster entity class and the SelectMethod to the GetPosterDetails method.The Item binding expression is available and we can retrieve properties of the Poster object.I retrieve the name, the image,the description and the price of each poster. 4) Now we need to write the GetPosterDetails method.In the code behind of the PosterDetails.aspx page we type public IQueryable<Poster> GetPosterDetails([QueryString("PosterID")]int? posterid) { PosterContext ctx = new PosterContext(); IQueryable<Poster> query = ctx.Posters; if (posterid.HasValue && posterid > 0) { query = query.Where(p => p.PosterID == posterid); } else { query = null; } return query; } I bind the value from the query string to the posterid parameter at run time.This is all possible due to the QueryStringAttribute class that lives inside the System.Web.ModelBinding and gets the value of the query string variable PosterID.If there is a matching poster it is fetched from the database.If not,there is no data at all coming back from the database. 5) I run my application and then click on the "Midfielders" link.Then click on the first poster that appears from the left (Kenny Dalglish) and click on it to see the details. Have a look at the picture below to see the results. You can see that now I have all the details of the poster in a new page.?ake sure you place breakpoints in the code so you can see what is really going on. Hope it helps!!!

Oracle Executive Strategy Brief: Enterprise-Grade Cloud Applications

- by B Shashikumar

Cloud Computing has clearly evolved into one of the dominant secular trends in the industry. Organizations are looking to the cloud to change how they buy and consume IT. And its no longer about just lower up-front costs. The cloud promises to deliver greater agility and free up resources to focus on innovation versus running and maintaining systems. But are organizations actually realizing these benefits? The full promise of cloud is not being realized by customers who entrust their business to multiple niche cloud providers. While almost 9 out of 10 companies expect more IT agility with cloud, only 47% are actually getting it (Source: 2011 State of Cloud Survey by Symantec). These niche cloud customers have also seen the promises of lower costs, efficiency gains, improved security, and compliance go unfulfilled. Having one cloud provider for customer relationship management (CRM) and another for human capital management (HCM), and then trying to glue these proprietary systems together while integrating to a back-office financial system can add to complexity and long-term costs. Completing a business process or generating an integrated report is cumbersome, and leverages incomplete data. Why can’t niche cloud providers deliver on the full promise of cloud? It’s simple: you still need to complete business processes. You still need reporting that enables you to take action using data from multiple systems. You still have to comply with SOX and other industry regulations. These requirements don’t go away just because you deploy in the cloud. Delivering lower up-front costs by enabling customers to buy software as a service (SaaS) is the easy part. To get real value that lasts longer than your quarterly report, it’s important to realize the benefits of cloud without compromising on functionality and while having the right level of control and flexibility. This is the true promise of cloud. Oracle’s cloud strategy centers around delivering the benefits of cloud—without compromise. We uniquely empower our customers with complete solutions and choice. From the richest functionality to integrated reporting and great user experience. It’s all available in the cloud. And it works not just with other Oracle cloud applications, but with your existing Oracle and third-party systems as well. This helps protect your current investments and extend their value as you journey to the cloud. We’ve made the necessary investments not only in our applications but also in the underlying technology that makes it all run—from the platform down to the hardware and operating system. We make it all. And we’ve engineered it to work together and be highly optimized for our customers, in the cloud. With Oracle enterprise-grade cloud applications, you get the benefits of cloud plus more power, more choice, and more confidence. Read more about how you can realize the true advantage of Cloud with Oracle Enterprise-grade Cloud applications in the Oracle Executive Strategy Brief here.

Disable Alt for window move in gnome-shell

- by artfulrobot

There are lots of posts on this about Unity, this is about gnome-shell As with other posters, I use apps (Inkscape in particular) that uses Alt-Click and Alt-drag. Gnome-shell is grabbing this off me and thus disabling features in the application. I have tried using ccsm's Move plugin - you can turn this off and you still get Alt-drag window moving. using gconf editor to change /apps/metacity/general/mouse_button_modifier - this has no effect AFAICS. It's really hindering me. Otherwise I find gnome-shell a really productive environment.

An icon has recently appeared on my panel with an exclamation mark. The message i get when hovering over this is that the update information is out of date, and that this may be caused by an unavailable repository or a network isssue.

Button "Add" is disabled in VPN Connection's dialog

- by Innuendo

I've just installed elementaryos-jupiter. (It's based on Ubuntu 10.10) I've entered VPN Connections' menu (nm - VPN Connections - Configure VPN) And there should be button "Add" - it is, but it's disabled (I can't press on it) I'm connecting via ethernet (LAN in a students' hostel) and we get internet via VPN connection (It worked for me in Ubuntu for a few years) Any suggestions? I've asked on IRC of elementaryos (there were few people) but they said that VPN is out-of-box, and it should work - they never met this.

Make windows smaller

- by JTS

Currently everything on my laptop takes up too much screen real estate. I can make the launcher icons smaller, the font smaller, I can use ctl-(minus) to make the contents of my browser smaller, but I was wondering if there was a way to do this all at once. Some way to just tell X to multiply the number of pixels anything should take by .75. If this is not possible, the main other thing I want to make smaller and have not been able to, is the top bar of any windows, the one with close/minimize/maximize buttons.

Run a VirtualBox VM in a second X-Server with Graphic support

- by Scindix

I'm starting a VirtualBox VM (Windows 7) in a second X-Server (Ubuntu 14.04) and i'm using the following xinit script (/path/.vboximage): optirun VBoxManage startvm <vm name> & exec tinywm I recognized that while running Virtualbox normally under Gnome (Unity to be precise ;-) ) I get full graphics support. But when I run it on a second xserver there seem to be some problems. E.g. Windows Aero doesn't seem to work and Chrome WebGL demos are running with poorer performance. I'm not a big Windows expert, so I don't know how I could check the used Graphic card (specification). But it is very obvious that something has changed when running the vm in the extra X-Server. Also when I try to replace tinywm with compiz I get the unity frame around the VM, which also seems to have no graphics acceleration (no transparency effects) So it seems that the X-Server doesn't have Graphic acceleration at all. I have a NVidia 525m and an Intel HD3000 which are both capable of advanced graphics. I'm starting the above script with startx /path/.vboximage - :1 How could I fix that?

How to setup VPN as Proxy

- by Nicolas Nox

I have an PerfectPrivacy VPN connected via the OpenVPN-Network-Manger-Plugin (Ubuntu 12.04.1) and I want to assign a system wide proxy over that VPN. I have tried proxydriver that should do that automatically, but it works partially. The browser says that I have the IP of the VPN, but when I tried to send an eMail over SMTP (Port 25), I can´t connect to the mail server. In our company the smtp server port is closed, but that should be not a problem, when I do that over a VPN, shouldn´t it? greetings

How to route KVM virtual machine audio to Ubuntu 11.10 host using virt-manager?

- by iGadget

I've been using KVM in combination with Virt-Manager and Remmina at a fair success up until now. The issue I need to solve now is to get audio from a virtualized Windows XP and make it audible on the Ubuntu 11.10 host. Remmina / RDP works for 'simple' audio (system sounds and such), but when the source gets trickier (e.g. Flash audio), Remmina / RDP messes up. So I figured I'd just connect to the machine directly using Virt-Manager. Unfortunately, it seems that even though I have successfully configured the AC97 audio device on WinXP, it's unable to get it's output to the Ubuntu host. This is probably because Virt-Manager uses VNC (and AFAIK, VNC doesn't transport audio). Does anyone know if there is a solution to fix this? I've heard of Spice, but the installation required so much voodoo last time I checked, I figured I'd let that solution boil to maturity a little longer ;) But perhaps there are other options I haven't thought of yet (which don't require switching to VirtualBox / VMware)...
