• weird characters in HTML email

  - by sims

  Hi stackers! I'm reading email from a maildir and some emails have weird sets of characters in them: =3D =09 I think =3D is = and =09 is a space. There are some others, but I'm not sure: =E2 =80 =93 Does anyone know what these are and what encoding issues I'm dealing with here? BTW, I tried fetching these email via POP3 and it's the same thing. The reason I'm posting this on SO is not because I'm using a regular mail client to read the data. I'm reading via PHP out of maildir files. Perhaps a regular email client would detect what encoding this is and deal with it. Thanks!

• Populate new row with VBA button click

  - by AME

  Hi, I am trying to create a list that adds a new row of data each time a button is clicked. I have the following code assigned to the button when clicked: PurchaseDate = InputBox("Enter Purchase Date:") Sheets("TrackRecord").Select i = 0 Row = i + 1 Range("A2").Select ActiveCell.FormulaR1C1 = Row Range("B2").Select ActiveCell.FormulaR1C1 = "=Dashboard!R26C4*(1/Dashboard!R26C12)" Range("C2").Select ActiveCell.FormulaR1C1 = "=Dashboard!R26C2" Range("D2").Select ActiveCell.FormulaR1C1 = PurchaseDate Range("E2").Select ActiveCell.FormulaR1C1 = "=Dashboard!R26C8 + R2C4" Range("F2").Select ActiveCell.FormulaR1C1 = "=Waterfall!R[8]C[5]" Range("F2").Select Selection.AutoFill Destination:=Range("F2:I2"), Type:=xlFillDefault Range("F2:I2").Select End Sub This code works fine, but I'd like it populate the next row below instead of overwriting the same row each time the button is clicked. I know that I have to iterate through the "Range("A2").select" section, e.g. "Range("A2").select" -- "Range("B2").select" .. But I don't know how to do this in VBA for Excel. That's why I am asking you folks ; ) . Thanks,

• Actionscript problems with social share encoding

  - by Rittmeyer

  Hi, I'm trying to make some "social share" buttons at my site, but the urls I generate just don't get decoded by this services. One example, for twitter: private function twitter(e:Event):void { var message:String = "Message with special chars âõáà"; var url:String = "http://www.twitter.com/home?status="; var link:URLRequest = new URLRequest( url + escape(message) ); } But when twitter opens up, the message is: Message with special chars %E2%F5%E1%E0 Something similar is happening with Facebook and Orkut (but these two hide the special chars). Someone know why is this happening?

• Algorithm to split an array into N groups based on item index (should be something simple)

  - by serg

  I feel that it should be something very simple and obvious but just stuck on this for the last half an hour and can't move on. All I need is to split an array of elements into N groups based on element index. For example we have an array of 30 elements [e1,e2,...e30], that has to be divided into N=3 groups like this: group1: [e1, ..., e10] group2: [e11, ..., e20] group3: [e21, ..., e30] I came up with nasty mess like this for N=3 (pseudo language, I left multiplication on 0 and 1 just for clarification): for(i=0;i<array_size;i++) { if(i>=0*(array_size/3) && i<1*(array_size/3) { print "group1"; } else if(i>=1*(array_size/3) && i<2*(array_size/3) { print "group2"; } else if(i>=2*(array_size/3) && i<3*(array_size/3) print "group3"; } } But what would be the proper general solution? Thanks.

• Https in java ends up with strange results

  - by Senne

  I'm trying to illustrate to students how https is used in java. But i have the feeling my example is not really the best out there... The code works well on my windows 7: I start the server, go to https://localhost:8080/somefile.txt and i get asked to trust the certificate, and all goes well. When I try over http (before or after accepting the certificate) I just get a blank page, which is ok for me. BUT when I try the exact same thing on my windows XP: Same thing, all goes well. But then (after accepting the certificate first), I'm also able to get all the the files through http! (if I first try http before https followed by accepting the certificate, I get no answer..) I tried refreshing, hard refreshing a million times but this should not be working, right? Is there something wrong in my code? I'm not sure if I use the right approach to implement https here... package Security; import java.io.*; import java.net.*; import java.util.*; import java.util.concurrent.Executors; import java.security.*; import javax.net.ssl.*; import com.sun.net.httpserver.*; public class HTTPSServer { public static void main(String[] args) throws IOException { InetSocketAddress addr = new InetSocketAddress(8080); HttpsServer server = HttpsServer.create(addr, 0); try { System.out.println("\nInitializing context ...\n"); KeyStore ks = KeyStore.getInstance("JKS"); char[] password = "vwpolo".toCharArray(); ks.load(new FileInputStream("myKeys"), password); KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509"); kmf.init(ks, password); SSLContext sslContext = SSLContext.getInstance("TLS"); sslContext.init(kmf.getKeyManagers(), null, null); // a HTTPS server must have a configurator for the SSL connections. server.setHttpsConfigurator (new HttpsConfigurator(sslContext) { // override configure to change default configuration. public void configure (HttpsParameters params) { try { // get SSL context for this configurator SSLContext c = getSSLContext(); // get the default settings for this SSL context SSLParameters sslparams = c.getDefaultSSLParameters(); // set parameters for the HTTPS connection. params.setNeedClientAuth(true); params.setSSLParameters(sslparams); System.out.println("SSL context created ...\n"); } catch(Exception e2) { System.out.println("Invalid parameter ...\n"); e2.printStackTrace(); } } }); } catch(Exception e1) { e1.printStackTrace(); } server.createContext("/", new MyHandler1()); server.setExecutor(Executors.newCachedThreadPool()); server.start(); System.out.println("Server is listening on port 8080 ...\n"); } } class MyHandler implements HttpHandler { public void handle(HttpExchange exchange) throws IOException { String requestMethod = exchange.getRequestMethod(); if (requestMethod.equalsIgnoreCase("GET")) { Headers responseHeaders = exchange.getResponseHeaders(); responseHeaders.set("Content-Type", "text/plain"); exchange.sendResponseHeaders(200, 0); OutputStream responseBody = exchange.getResponseBody(); String response = "HTTP headers included in your request:\n\n"; responseBody.write(response.getBytes()); Headers requestHeaders = exchange.getRequestHeaders(); Set<String> keySet = requestHeaders.keySet(); Iterator<String> iter = keySet.iterator(); while (iter.hasNext()) { String key = iter.next(); List values = requestHeaders.get(key); response = key + " = " + values.toString() + "\n"; responseBody.write(response.getBytes()); System.out.print(response); } response = "\nHTTP request body: "; responseBody.write(response.getBytes()); InputStream requestBody = exchange.getRequestBody(); byte[] buffer = new byte[256]; if(requestBody.read(buffer) > 0) { responseBody.write(buffer); } else { responseBody.write("empty.".getBytes()); } URI requestURI = exchange.getRequestURI(); String file = requestURI.getPath().substring(1); response = "\n\nFile requested = " + file + "\n\n"; responseBody.write(response.getBytes()); responseBody.flush(); System.out.print(response); Scanner source = new Scanner(new File(file)); String text; while (source.hasNext()) { text = source.nextLine() + "\n"; responseBody.write(text.getBytes()); } source.close(); responseBody.close(); exchange.close(); } } }

• Unicode and URI encoding, decoding and escaping in JavaScript

  - by apphacker

  If you look at this table here, it has a list of escape sequences for Unicode characters that don't actually work for me. For example for "%96", which should be a –, I get an error when trying decode: decodeURIComponent("%96"); URIError: URI malformed If I attempt to encode "–" I actually get: encodeURIComponent("–"); "%E2%80%93" I searched through the internet and I saw this page, which mentions using escape and unescape with decodeURIComponent and encodeURIComponent respectively. This doesn't seem to help because %96 doesn't show up as "–" no matter what I try and this of course wouldn't work: decodeURIComponent(escape("%96)); "%96" Not very helpful. How can I get "%96" to be a "–" with JavaScript (without hardcoding a map for every single possible unicode character I may run into)?

• VB.NET encoding one character wrong

  - by Nick Spiers

  I have a byte array that I'm encoding to a string: Private Function GetKey() As String Dim ba() As Byte = {&H47, &H43, &H44, &H53, &H79, &H73, &H74, &H65, &H6D, &H73, &H89, &HA, &H1, &H32, &H31, &H36} Dim strReturn As String = Encoding.ASCII.GetString(ba) Return strReturn End Function Then I write that to a file via IO.File.AppendAllText. If I open that file in 010 Editor (to view the binary data) it displays as this: 47 43 44 53 79 73 74 65 6D 73 3F 0A 01 32 31 36 The original byte array contained 89 at position 11, and the encoded string contains 3F. If I change my encoding to Encoding.Default.GetString, it gives me: 47 43 44 53 79 73 74 65 6D 73 E2 80 B0 0A 01 32 31 36 Any help would be much appreciated!

• OS X Terminal: Meta key + alt functionality at the same time

  - by abababa22

  Is there a way to use "alt/option" key as a meta key but still be able to use the key to make some characters which need it? For example in my local keyboard layout: @ is alt-2 \ is alt-shift-7 | is alt-7 etc. So if I set alt as meta key, I can't make those characters. On the other hand using "press esc, release esc, press a key" to make meta key sequences makes my hands hurt. Any emacs users with international keyboards who have solved this, please give any tips you might have! :) edit: It appears that I can set alt as meta key and then add these kind of settings in inputrc: "\e2": "@" This works in bash shell but it still won't work with emacs though, so no good.

• How do I view the parameters of currently running procs in SQL Server 2008

  - by Pez

  I am trying to troubleshoot an issue that is popping up on our new SQL Server. While viewing the running processes (sp_who2) I can't tell what parameters a proc was started with. I can find the name of the proc using: DBCC INPUTBUFFER (spid) I can even find some additional info, but I can't see a way to show the parameters. (http://sqlserverpedia.com/blog/sql-server-bloggers/sql-server-%E2%80%93-get-last-running-query-based-on-spid/) I know I can see the parameters if I do a trace, but that doesn't help in this case.

• Oracle WebCenter Portal: Pagelet Producer – What’s New in 11.1.1.6.0 Release

  - by kellsey.ruppel

  Igor Plyakov, Sr. Principal Product Marketing Manager is back to share what's new in Oracle WebCenter Portal: Pagelet Producer. In February 2012 Oracle released 11g Release 1 (11.1.1.6.0) for WebCenter Portal. Pagelet Producer (aka Ensemble) that came out with this release added support for several new capabilities that are described in this post. As of 11.1.1.5.0 release the Pagelet Producer can expose WSRP and JPDK portlets as pagelets that can then be consumed in any portal or any third-party application that does not have a WSRP consumer. Now Pagelet Producer team is working on simplifying use of pagelets in WebCenter Sites. To expose WSRP portlets a new Producer should be registered with Pagelet Producer which can be done using Enterprise Manager, WLST or the Pagelet Producer Administration Console (for details see Section 25.9 of Administrator’s Guide for Oracle WebCenter Portal). If the producer requires authentication, Pagelet Producer allows you to select and use one of standard WSS token profiles.  After registration is finished a new resource is created and automatically populated with pagelets that represent the portlets associated with the WSRP endpoint.  For 11.1.1.6.0 release we completed extensive testing of consuming all WebCenter Services that are exposed as WSRP portlets by E2.0 Producer and delivery them as pagelets to WebCenter Interaction portal. In Pagelet Producer 11.1.1.6.0 release we added OpenSocial container that allows consuming gadgets from other OpenSocial containers, e.g. iGoogle, and expose them as pagelets. You can also use Pagelet Producer to host OpenSocial gadgets that could leverage OpenSocial APIs that it supports – People, Activities, Appdata and Pub-Sub features. Note that People and Activities expose the People Connections and Activity Stream from WebCenter Portal, i.e. to use these features Pagelet Producer requires connection to WebCenter Portal schema. Pub-Sub allows leveraging OpenAJAX Hub API for inter-gadget communication. In addition to these major new additions in Pagelet Producer 11.1.1.6.0 release we also extended several functional modules: The Clipping module was extended to support clipping of multiple regions on web resource page and then re-assembly of these separately clipped regions into a single pagelet. The auto-login feature can now be applied to web resources protected with Kerberos authentication; you would find this new functionality handy for consuming SharePoint web parts The logging module now supports full HTTP traffic between the Pagelet Producer and proxied web resource. At last, as the rest of WebCenter Portal stack the Pagelet Producer 11.1.1.6.0 can run on IBM WebSphere Application Server.

In this blog series we will review an existing OpenStack setup using the Oracle OpenStack Tech Preview and explain the different network components through use cases and examples. The goal is to show how the different pieces come together and provide a bigger picture view of the network architecture in OpenStack. This can be very helpful to users making their first steps in OpenStack or anyone wishes to understand how networking works in this environment.  We will go through the basics first and build the examples as we go. According to the recent Icehouse user survey and the one before it, Neutron with Open vSwitch plug-in is the most widely used network setup both in production and in POCs (in terms of number of customers) and so in this blog series we will analyze this specific OpenStack networking setup. As we know there are many options to setup OpenStack networking and while Neturon + Open vSwitch is the most popular setup there is no claim that it is either best or the most efficient option. Neutron + Open vSwitch is an example, one which provides a good starting point for anyone interested in understanding OpenStack networking. Even if you are using different kind of network setup such as different Neutron plug-in or even not using Neutron at all this will still be a good starting point to understand the network architecture in OpenStack. The setup we are using for the examples is the one used in the Oracle OpenStack Tech Preview. Installing it is simple and it would be helpful to have it as reference. In this setup we use eth2 on all servers for VM network, all VM traffic will be flowing through this interface.The Oracle OpenStack Tech Preview is using VLANs for L2 isolation to provide tenant and network isolation. The following diagram shows how we have configured our deployment: This first post is a bit long and will focus on some basic concepts in OpenStack networking. The components we will be discussing are Open vSwitch, network namespaces, Linux bridge and veth pairs. Note that this is not meant to be a comprehensive review of these components, it is meant to describe the component as much as needed to understand OpenStack network architecture. All the components described here can be further explored using other resources. Open vSwitch (OVS) In the Oracle OpenStack Tech Preview OVS is used to connect virtual machines to the physical port (in our case eth2) as shown in the deployment diagram. OVS contains bridges and ports, the OVS bridges are different from the Linux bridge (controlled by the brctl command) which are also used in this setup. To get started let’s view the OVS structure, use the following command: # ovs-vsctl show 7ec51567-ab42-49e8-906d-b854309c9edf     Bridge br-int         Port br-int             Interface br-int type: internal         Port "int-br-eth2"             Interface "int-br-eth2"     Bridge "br-eth2"         Port "br-eth2"             Interface "br-eth2" type: internal         Port "eth2"             Interface "eth2"         Port "phy-br-eth2"             Interface "phy-br-eth2" ovs_version: "1.11.0" We see a standard post deployment OVS on a compute node with two bridges and several ports hanging off of each of them. The example above is a compute node without any VMs, we can see that the physical port eth2 is connected to a bridge called “br-eth2”. We also see two ports "int-br-eth2" and "phy-br-eth2" which are actually a veth pair and form virtual wire between the two bridges, veth pairs are discussed later in this post. When a virtual machine is created a port is created on one the br-int bridge and this port is eventually connected to the virtual machine (we will discuss the exact connectivity later in the series). Here is how OVS looks after a VM was launched: # ovs-vsctl show efd98c87-dc62-422d-8f73-a68c2a14e73d     Bridge br-int         Port "int-br-eth2"             Interface "int-br-eth2"         Port br-int             Interface br-int type: internal         Port "qvocb64ea96-9f" tag: 1             Interface "qvocb64ea96-9f"     Bridge "br-eth2"         Port "phy-br-eth2"             Interface "phy-br-eth2"         Port "br-eth2"             Interface "br-eth2" type: internal         Port "eth2"             Interface "eth2" ovs_version: "1.11.0" Bridge "br-int" now has a new port "qvocb64ea96-9f" which connects to the VM and tagged with VLAN 1. Every VM which will be launched will add a port on the “br-int” bridge for every network interface the VM has. Another useful command on OVS is dump-flows for example: # ovs-ofctl dump-flows br-int NXST_FLOW reply (xid=0x4): cookie=0x0, duration=735.544s, table=0, n_packets=70, n_bytes=9976, idle_age=17, priority=3,in_port=1,dl_vlan=1000 actions=mod_vlan_vid:1,NORMAL cookie=0x0, duration=76679.786s, table=0, n_packets=0, n_bytes=0, idle_age=65534, hard_age=65534, priority=2,in_port=1 actions=drop cookie=0x0, duration=76681.36s, table=0, n_packets=68, n_bytes=7950, idle_age=17, hard_age=65534, priority=1 actions=NORMAL As we see the port which is connected to the VM has the VLAN tag 1. However the port on the VM network (eth2) will be using tag 1000. OVS is modifying the vlan as the packet flow from the VM to the physical interface. In OpenStack the Open vSwitch agent takes care of programming the flows in Open vSwitch so the users do not have to deal with this at all. If you wish to learn more about how to program the Open vSwitch you can read more about it at http://openvswitch.org looking at the documentation describing the ovs-ofctl command. Network Namespaces (netns) Network namespaces is a very cool Linux feature can be used for many purposes and is heavily used in OpenStack networking. Network namespaces are isolated containers which can hold a network configuration and is not seen from outside of the namespace. A network namespace can be used to encapsulate specific network functionality or provide a network service in isolation as well as simply help to organize a complicated network setup. Using the Oracle OpenStack Tech Preview we are using the latest Unbreakable Enterprise Kernel R3 (UEK3), this kernel provides a complete support for netns. Let's see how namespaces work through couple of examples to control network namespaces we use the ip netns command: Defining a new namespace: # ip netns add my-ns # ip netns list my-ns As mentioned the namespace is an isolated container, we can perform all the normal actions in the namespace context using the exec command for example running the ifconfig command: # ip netns exec my-ns ifconfig -a lo        Link encap:Local Loopback           LOOPBACK  MTU:16436 Metric:1           RX packets:0 errors:0 dropped:0 overruns:0 frame:0           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0           RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b) We can run every command in the namespace context, this is especially useful for debug using tcpdump command, we can ping or ssh or define iptables all within the namespace. Connecting the namespace to the outside world: There are various ways to connect into a namespaces and between namespaces we will focus on how this is done in OpenStack. OpenStack uses a combination of Open vSwitch and network namespaces. OVS defines the interfaces and then we can add those interfaces to namespace. So first let's add a bridge to OVS: # ovs-vsctl add-br my-bridge Now let's add a port on the OVS and make it internal: # ovs-vsctl add-port my-bridge my-port # ovs-vsctl set Interface my-port type=internal And let's connect it into the namespace: # ip link set my-port netns my-ns Looking inside the namespace: # ip netns exec my-ns ifconfig -a lo        Link encap:Local Loopback           LOOPBACK  MTU:65536 Metric:1           RX packets:0 errors:0 dropped:0 overruns:0 frame:0           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0           RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b) my-port   Link encap:Ethernet HWaddr 22:04:45:E2:85:21           BROADCAST  MTU:1500 Metric:1           RX packets:0 errors:0 dropped:0 overruns:0 frame:0           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0           RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b) Now we can add more ports to the OVS bridge and connect it to other namespaces or other device like physical interfaces. Neutron is using network namespaces to implement network services such as DCHP, routing, gateway, firewall, load balance and more. In the next post we will go into this in further details. Linux Bridge and veth pairs Linux bridge is used to connect the port from OVS to the VM. Every port goes from the OVS bridge to a Linux bridge and from there to the VM. The reason for using regular Linux bridges is for security groups’ enforcement. Security groups are implemented using iptables and iptables can only be applied to Linux bridges and not to OVS bridges. Veth pairs are used extensively throughout the network setup in OpenStack and are also a good tool to debug a network problem. Veth pairs are simply a virtual wire and so veths always come in pairs. Typically one side of the veth pair will connect to a bridge and the other side to another bridge or simply left as a usable interface. In this example we will create some veth pairs, connect them to bridges and test connectivity. This example is using regular Linux server and not an OpenStack node: Creating a veth pair, note that we define names for both ends: # ip link add veth0 type veth peer name veth1 # ifconfig -a . . veth0     Link encap:Ethernet HWaddr 5E:2C:E6:03:D0:17           BROADCAST MULTICAST  MTU:1500 Metric:1           RX packets:0 errors:0 dropped:0 overruns:0 frame:0           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000           RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b) veth1     Link encap:Ethernet HWaddr E6:B6:E2:6D:42:B8           BROADCAST MULTICAST  MTU:1500 Metric:1           RX packets:0 errors:0 dropped:0 overruns:0 frame:0           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000           RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b) . . To make the example more meaningful this we will create the following setup: veth0 => veth1 => br-eth3 => eth3 ======> eth2 on another Linux server br-eth3 – a regular Linux bridge which will be connected to veth1 and eth3 eth3 – a physical interface with no IP on it, connected to a private network eth2 – a physical interface on the remote Linux box connected to the private network and configured with the IP of 50.50.50.1 Once we create the setup we will ping 50.50.50.1 (the remote IP) through veth0 to test that the connection is up: # brctl addbr br-eth3 # brctl addif br-eth3 eth3 # brctl addif br-eth3 veth1 # brctl show bridge name     bridge id               STP enabled     interfaces br-eth3         8000.00505682e7f6       no              eth3                                                         veth1 # ifconfig veth0 50.50.50.50 # ping -I veth0 50.50.50.51 PING 50.50.50.51 (50.50.50.51) from 50.50.50.50 veth0: 56(84) bytes of data. 64 bytes from 50.50.50.51: icmp_seq=1 ttl=64 time=0.454 ms 64 bytes from 50.50.50.51: icmp_seq=2 ttl=64 time=0.298 ms When the naming is not as obvious as the previous example and we don't know who are the paired veth interfaces we can use the ethtool command to figure this out. The ethtool command returns an index we can look up using ip link command, for example: # ethtool -S veth1 NIC statistics: peer_ifindex: 12 # ip link . . 12: veth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 Summary That’s all for now, we quickly reviewed OVS, network namespaces, Linux bridges and veth pairs. These components are heavily used in the OpenStack network architecture we are exploring and understanding them well will be very useful when reviewing the different use cases. In the next post we will look at how the OpenStack network is laid out connecting the virtual machines to each other and to the external world. @RonenKofman

• Unable to transfer data to or from mounted hard drive

  - by user210335

  So usually i'm good at sorting out issues. But this one has me at a loss! This issues has occured since upgrading my ubuntu so this was workingg prior. I use mounted hard drives to manage my downloads which are then copied over accordingly by a python based app. I found it was having issues with permissions to create anything on these mounted hard drives. I'm able to play and access he content of these drives so they're not faulty. My mount script looks like the following rw,user,exec,auto I really am stuck. Could anyone shed any light on how to fix this and allow me to access it. I've checked the properties and all groups should have read and write access so i'm very confused! thanks, edit here's the output of my mount options /dev/sda2 on / type ext4 (rw,errors=remount-ro) proc on /proc type proc (rw,noexec,nosuid,nodev) sysfs on /sys type sysfs (rw,noexec,nosuid,nodev) none on /sys/fs/cgroup type tmpfs (rw) none on /sys/fs/fuse/connections type fusectl (rw) none on /sys/kernel/debug type debugfs (rw) none on /sys/kernel/security type securityfs (rw) none on /sys/firmware/efi/efivars type efivarfs (rw) udev on /dev type devtmpfs (rw,mode=0755) devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620) tmpfs on /run type tmpfs (rw,noexec,nosuid,size=10%,mode=0755) none on /run/lock type tmpfs (rw,noexec,nosuid,nodev,size=5242880) none on /run/shm type tmpfs (rw,nosuid,nodev) none on /run/user type tmpfs (rw,noexec,nosuid,nodev,size=104857600,mode=0755) none on /sys/fs/pstore type pstore (rw) /dev/sda1 on /boot/efi type vfat (rw) /dev/sdc1 on /mnt/tv type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096) /dev/sdb1 on /mnt/B88A30E88A30A4B2 type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096) systemd on /sys/fs/cgroup/systemd type cgroup (rw,noexec,nosuid,nodev,none,name=systemd) gvfsd-fuse on /run/user/1000/gvfs type fuse.gvfsd-fuse (rw,nosuid,nodev,user=simon) /dev/sdd1 on /media/simon/New Volume3 type fuseblk (rw,nosuid,nodev,allow_other,default_permissions,blksize=4096) the main mount in question is /dev/sdc1 on /mnt/tv type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096) heres my dmesg output. I tried cchanging permissions in a terminal and I got an io error.

• Turn off keyboard back-light Sony (VAIO SVF1521DCXW)

  - by KasiyA

  I have a Sony laptop and I want to turn keyboard back-light off. It doesn't have a shortcut function key for doing this on the keyboard . I can turn off it with VAIO Control Center in Windows but I don't know how can I turn it off in Ubuntu 14.04. There isn't available to me: /sys/devices/platform/sony-laptop/kbd_backlight doesn't exist on my machine. I have this folder /sys/devices/platform/sony-laptop/ and there is three folder one power folder and two shortcut-ed folder driver , subsystem and five file contains battery_care_health , battery_care_limiter , modalias , touchpad and event This is the output of running sudo modinfo sony-laptop: filename: /lib/modules/3.13.0-34-generic/kernel/drivers/platform/x86/sony-laptop.ko version: 0.6 license: GPL description: Sony laptop extras driver (SPIC and SNC ACPI device) author: Stelian Pop, Mattia Dongili srcversion: 5C6E050349475558A231C59 alias: acpi*:SNY6001:* alias: acpi*:SNY5001:* depends: intree: Y vermagic: 3.13.0-34-generic SMP mod_unload modversions signer: Magrathea: Glacier signing key sig_key: 50:0B:C5:C8:7D:4B:11:5C:F3:C1:50:4F:7A:92:E2:33:C6:14:3D:58 sig_hashalgo: sha512 parm: debug:set this to 1 (and RTFM) if you want to help the development of this driver (int) parm: no_spic:set this if you don't want to enable the SPIC device (int) parm: compat:set this if you want to enable backward compatibility mode (int) parm: mask:set this to the mask of event you want to enable (see doc) (ulong) parm: camera:set this to 1 to enable Motion Eye camera controls (only use it if you have a C1VE or C1VN model) (int) parm: minor:minor number of the misc device for the SPIC compatibility code, default is -1 (automatic) (int) parm: kbd_backlight:set this to 0 to disable keyboard backlight, 1 to enable it (default: no change from current value) (int) parm: kbd_backlight_timeout:meaningful values vary from 0 to 3 and their meaning depends on the model (default: no change from current value) (int) With the suggested command: sudo modprobe -r sony_laptop sudo modprobe -v sony_laptop kbd_backlight=0 Output was: insmod /lib/modules/3.13.0-34-generic/kernel/drivers/platform/x86/sony-laptop.ko kbd_backlight=0 It doesn't seem to affect the keyboard backlight. And also trying this command: sudo modprobe -v sony_laptop kbd_backlight_timeout=3 kbd_backlight=0 and doesn't seem to effect the keyboard backlight I also test it after restart laptop, And I didn't see any effect too. Important : By default, keyboard backlight is off; when I press a key it turns on and after 15 seconds it turns off again. It's the same result on battery and AC power I followed also http://ubuntuforums.org/showthread.php?t=2139597 and Keyboard backlighting not working on a Vaio VPCSB11FX but didn't work so.

• Difference between EJB Persist & Merge operation

  - by shantala.sankeshwar

  This article gives the difference between EJB Persist & Merge operations with scenarios.Use Case Description Users working on EJB persist & merge operations often have this question in mind " When merge can create new entity as well as modify existing entity,then why do we have 2 separate operations - persist & merge?" The reason is very simple.If we use merge operation to create new entity & if the entity exists then it does not throw any exception,but persist throws exception if the entity already exists.Merge should be used to modify the existing entity.The sql statement that gets executed on persist operation is insert statement.But in case of merge first select statement gets executed & then update sql statement gets executed.Scenario 1: Persist operation to create new Emp recordLet us suppose that we have a Java EE Web Application created with Entities from Emp table & have created session bean with data control. Drop Emp Object(Expand SessionEJBLocal->Constructors under Data Controls) as ADF Parameter form in jspx pageDrop persistEmp(Emp) as ADF CommandButton & provide #{bindings.EmpIterator.currentRow.dataProvider} as the value for emp parameter.Then run this page & provide values for Emp,click on 'persistEmp' button.New Emp record gets created.So when we execute persist operation only insert sql statement gets executed :INSERT INTO EMP (EMPNO, COMM, HIREDATE, ENAME, JOB, DEPTNO, SAL, MGR) VALUES (?, ?, ?, ?, ?, ?, ?, ?)    bind => [2, null, null, e2, null, 10, null, null]Scenario 2: Merge operation to modify existing Emp recordLet us suppose that we have a Java EE Web Application created with Entities from Emp table & have created session bean with data control.Drop empFindAll() Object as ADF form on jspx page.Drop mergeEmp(Emp) operation as commandButton & provide #{bindings.EmpIterator.currentRow.dataProvider} as the value for emp parameter.Then run this page & modify values for Emp record,click on 'mergeEmp' button.The respective Emp record gets modified.So when we execute merge operation select & update sql statements gets executed :SELECT EMPNO, COMM, HIREDATE, ENAME, JOB, DEPTNO, SAL, MGR FROM EMP WHERE (EMPNO = ?) bind => [7566]UPDATE EMP SET ENAME = ? WHERE (EMPNO = ?) bind => [KINGS, 7839]

• GRUB doesn't recognize partitions on one harddisk

  - by knizz

  I have a dualboot computer with Windows Vista (on hd0) and Ubuntu 9.10. The bootloader is GRUB and the windows bootloader lets me decide between Vista and Ubuntu-Installation (broken WuBi). But now (i don't know why that changed) I can't use start the windows-bootloader anymore. I tried "ls" on the grub-prompt and it gave me a list like: (hd0) (hd1) (hd1,0) (hd1,1) (hd1,2) ... (fd0) It recognizes all partitions of hd1 (the ubuntu-harddisk) but not of hd0(the win-disk). .. WHY? Here is the result of the "boot info script" for the technical details: Boot Info Script 0.55 dated February 15th, 2010 ============================= Boot Info Summary: ============================== => Grub 2 is installed in the MBR of /dev/sda and looks for (UUID=a7c510e3-2399-437b-ab92-fa609e48d63f)/boot/grub. => No boot loader is installed in the MBR of /dev/sdb sda1: _________________________________________________________________________ File system: ntfs Boot sector type: Windows Vista/7 Boot sector info: No errors found in the Boot Parameter Block.

• KVM work with bridge network problems

  - by isware

  I try to configure bridge network for KVM(refer to http://www.linux-kvm.org/page/Networking), and it worked for Guest OS, but I have two problems with my Fedora host OS: 1?I can not access internet on host 2?The bridge configuration lost after reboot, I need to execute "service network restart" again to bring it up I checked here(http://serverfault.com/questions/168119/kvm-network-bridge-with-public-static-ip-for-both-host-and-guests) for the first problem, it seems not working for me.

• Very slow write performance on Debian 6.0 (AMD64) with DMCRYPT/LVM/RAID1

  - by jdelic

  I'm seeing very strange performance characteristics on one of my servers. This server is running a simple two-disk software-RAID1 setup with LVM spanning /dev/md0. One of the logical volumes /dev/vg0/secure is encrypted using dmcrypt with LUKS and mounted with the sync and noatimes flag. Writing to that volume is incredibly slow at 1.8 MB/s and the CPU usage stays near 0%. There are 8 crpyto/1-8 processes running (it's a Intel Quadcore CPU). I hope that someone on serverfault has seen this before :-(. uname -a 2.6.32-5-xen-amd64 #1 SMP Tue Mar 8 00:01:30 UTC 2011 x86_64 GNU/Linux Interestingly, when I read from the device I get good performance numbers: reading without encryption: $ dd if=/dev/vg0/secure of=/dev/null bs=64k count=100000 100000+0 records in 100000+0 records out 6553600000 bytes (6.6 GB) copied, 68.8951 s, 95.1 MB/s reading with encryption: $ dd if=/dev/mapper/secure of=/dev/null bs=64k count=100000 100000+0 records in 100000+0 records out 6553600000 bytes (6.6 GB) copied, 69.7116 s, 94.0 MB/s However, when I try to write to the device: $ dd if=/dev/zero of=./test bs=64k 8809+0 records in 8809+0 records out 577306624 bytes (577 MB) copied, 321.861 s, 1.8 MB/s Also, when I read I see CPU usage, when I write, the CPU stays at almost 0% usage.

• Recovering a mdadm+lvm+ext4 partition with read error

  - by bitwelder

  One of disks in my NAS has failed. The NAS is running Linux, and it uses mdadm + LVM technology for its filesystems. I do have backup for most of the contents, but not for the very last changes, and if possible, I'd like to recover that from this failing disk. The disk (a 'green drive' WD10EARS 1TB in size) throws this kind of errors: Oct 3 12:00:41 kernel: [ 3625.620000] ata5.00: read unc at 9453282 Oct 3 12:00:41 kernel: [ 3625.620000] lba 9453282 start 9453280 end 1953511007 Oct 3 12:00:41 kernel: [ 3625.620000] sde5 auto_remap 0 Oct 3 12:00:41 kernel: [ 3625.630000] ata5.00: exception Emask 0x0 SAct 0x1 SErr 0x0 action 0x6 Oct 3 12:00:41 kernel: [ 3625.630000] ata5.00: edma_err_cause=00000084 pp_flags=00000003, dev error, EDMA self-disable Oct 3 12:00:41 kernel: [ 3625.640000] ata5.00: failed command: READ FPDMA QUEUED Oct 3 12:00:41 kernel: [ 3625.650000] ata5.00: cmd 60/40:00:e0:3e:90/00:00:00:00:00/40 tag 0 ncq 32768 in Oct 3 12:00:41 kernel: [ 3625.650000] res 41/40:00:e2:3e:90/12:00:00:00:00/40 Emask 0x409 (media error) <F> Oct 3 12:00:41 kernel: [ 3625.660000] ata5.00: status: { DRDY ERR } However, while testing with 'dd', I noticed that if I skip the first 4kB, the read seems to be ok, i.e. a command like. dd if=/dev/sde5 of=dev/null bs=4k count=1000 skip=1 doesn't return any read error. Supposing that there is no other read failure in the rest of the disk, would I be able to recover this 900 GB partition (as I mentioned before, it's a 'linux raid autodetect' partition, that contains a a LVM2 volume that contains a ext4 filesystem) if I copy-clone the partition somewhere else, but the first 4kB?

• Advanced cell selection in Excel

  - by Supuhstar

  I am new to this flavor of StackExchange, so if this belongs elsewhere, please move it; I figured this would be the best place, though. I am making an Excel Worksheet that simply stores basic financial data in 5 columns (Check Number, Date of Transaction, Description, Profit from Transaction, and Balance After Transaction) and indefinite rows. Each worksheet represents one month, and each Workbook represents a year. As I make or receive a payment, I store it as a new row, which, inherently, makes the number of rows per month indefinite. Each transaction's Balance cell is the sum of the Balance cell of the row above it and the Profit cell of its row. I want each month to start off with a special row (first one after column headers) that displays a summary of the last month's transactions. For instance, the Balance After Transaction cell would display the last row's balance, and the Profit from Transaction cell would display the overall profits of the month) I know that if I knew every month had exactly 100 expenses, I could achieve this for March with the following formulas for profit and balance, respectively: =February!E2 - February!E102 =February!E102 However, I do NOT know how many rows will be in each month's table, and I'd like to automate this as much as possible (for instance, if I find a missed or duplicated expense in January, I don't want to have to update all the formulas that point to the ending January balance). How can I have Excel automatically use the last entered value in a column, in any given Excel spreadsheet, in a formula?
