• select tag sits one pixel lower in Firefox than it does in Chrome

  - by sepoto

  #allday { width: 180px; height: 20px; margin-top: 2px !important; margin-right: 0px; padding: 0px; -webkit-appearance: menulist; box-sizing: border-box; -webkit-box-align: center; border: 1px solid; border-image: initial; white-space: pre; -webkit-rtl-ordering: logical; color: black; background-color: white; cursor: default; } I inspected the element in both browsers but I'm not really seeing where the discrepancy is. Has anyone been through this before with the select tag?

• Django GenericRelation doesn't save related object's id - is this a bug or am I doing it wrong?

  - by pinkeen

  I have a model with a generic relation (call it A), when creating an instance of this object I pass an instance of another model (call it B) as the initializer of the content_object field (via kwargs of the constructor). If I don't save B before creating A then when saving A the content_object_id is saved to the db as NULL. If I save B before passing it to the constructor of A then everything's allright. It's not logical. I assumed that the ID of the related object (B) is fetched when doing A.save() and it should throw some kind of an exception if B isn't saved yet but it just fails silently. I don't like the current solution (saving B beforhand) because we don't know yet if I will be always willing to keep the object, not just scrap it, and there are performance considerations - what if I will add some another data and save it once more shortly after. class BaseNodeData(models.Model): ... extnodedata_content_type = models.ForeignKey(ContentType, null=True) extnodedata_object_id = models.PositiveIntegerField(null=True) extnodedata = generic.GenericForeignKey(ct_field='extnodedata_content_type', fk_field='extnodedata_object_id') class MarkupNodeData(models.Model): raw_content = models.TextField() Suppose we do: markup = MarkupNodeData(raw_content='...') base = BaseNodeData(..., extnodedata=markup) markup.save() base.save() # both records are inserted to the DB but base is stored with extnodedata_object_id=NULL markup = MarkupNodeData(raw_content='...') base = BaseNodeData(..., extnodedata=markup) base.save() markup.save() # no exception is thrown and everything is the same as above markup = MarkupNodeData(raw_content='...') markup.save() base = BaseNodeData(..., extnodedata=markup) base.save() # this works as expected Of course I can do it this way, but it doesn't change anything: base = BaseNodeData(...) base.extnodedata = markup My question is - is this a bug in django which I should report or maybe I'm doing something wrong. Docs on GenericRelations aren't exactly verbose.

• Changing CCK content-types details results in numerous DB calls for the menu system

  - by Paul Strugger

  Every time I make a change in the details of a content-type it takes too long. I though it had to do with the fact that I had too many content-types and fields (~500), but when I load the devel module to see the queries that take that long I see: Executed 32212 queries in 12267.57 milliseconds. Queries taking longer than 5 ms and queries executed more than once, are highlighted. Page execution time was 55763.32 ms When I see the details I notice that the vast majority of db calls come from the menu system, e.g.: _menu_route menu_local_tasks admin_menu_link_save Why is that? Can I avoid some of these? It doesn't seem logical!

• Reading function pointer syntax

  - by bobobobo

  Everytime I look at a C function pointer, my eyes glaze over. I can't read them. From here, here are 2 examples of function pointer TYPEDEFS: typedef int (*AddFunc)(int,int); typedef void (*FunctionFunc)(); Now I'm used to something like: typedef vector<int> VectorOfInts ; Which I read as typedef vector<int> /* as */ VectorOfInts ; But I can't read the above 2 typedefs. The bracketing and the asterisk placement, it's just not logical. Why is the * beside the word AddFunc..?

• BlackBerry - Multiple Screens or Single Screen with Content Manager?

  - by Max Gontar

  Hi! I've seen projects which use many screens each one for different layout and functionality. I've seen projects with only one screen (like wizard workflow) where content is changed on user interaction (and this seems to be logical to use single screen in wizards). But also I've seen projects (apps like game or messenger or phone settings utility) which use single screen for different functionalities. I can see such advantages of having single screen in app: keep same decoration design and menu or toolbar (which may be also achieved with inheritance) keep single screen in ui stack (which may be achieved by pop/push screen) easy to handle data over application Can you tell other advantages/disadvantages of single screen app? When its better to use this approach? Thank you!

• Adding characters to string

  - by Jamza

  I am currently trying to build a very basic serial shell with my arduino. I am able to get an output from the device using Serial.read() and can get the character it has outputted, but I cannot work out how to then add that character to a longer to form the full command. I tried the logical thing but it doesn't work: char Command[]; void loop(){ if(Serial.available() > 0){ int clinput = Serial.read(); Command = Command + char(clinput); } Can anybody help? Thank You.

• c++: at what point should I start using "new char[N]" vs a static buffer "char[Nmax]"

  - by dan

  My question is with regard to C++ Suppose I write a function to return a list of items to the caller. Each item has 2 logical fields: 1) an int ID, and 2) some data whose size may vary, let's say from 4 bytes up to 16Kbytes. So my question is whether to use a data structure like: struct item { int field1; char field2[MAX_LEN]; OR, rather, to allocate field2 from the heap, and require the caller to destroy when he's done: struct item{ int field1; char *field2; // new char[N] -- destroy[] when done! Since the max size of field #2 is large, is makes sense that this would be allocated from the heap, right? So once I know the size N, I call field2 = new char[N], and populate it. Now, is this horribly inefficient? Is it worse in cases where N is always small, i.e. suppose I have 10000 items that have N=4?

• The right way to implement communication between java objects

  - by imoschak

  I'm working on an academic project which simulates a rather large queuing procedure in java. The core of the simulator rests within one package where there exist 8 classes each one implementing a single concept. Every class in the project follows SRP. These classes encapsulate the behavior of the simulator and inter-connect every other class in the project. The problem that I has arisen is that most of these 8 classes are, as is logical i think, tightly coupled and each one has to have working knowledge of every other class in this package in order to be able to call methods from it when needed. The application needs only one instance of each class so it might be better to create static fields for each class in a new class and use that to make calls -instead of preserving a reference in each class for every other class in the package (which I'm certain that is incorrect)-, but is this considered a correct design solution? or is there a design pattern maybe that better suits my needs?

  Possible Duplicate: What does !! mean in ruby? Ruby, !! operator (a/k/a the double-bang) Sometimes I see a Ruby code like this def sent? !!@sent_at end It seems to be not logical. Is it necessary to use here double !? As far as I'm concerned, it might be just def sent? @sent_at end UPDATE: then what is the difference between these def sent? !!@sent_at end def sent? @sent_at.nil? end def sent? @sent_at == nil end

• Can't remove GPT data from MBR

  - by user2373121

  I am having difficulty getting the Ubuntu installer (and gparted) to recognize the partitions on my MBR type disk. Other operating systems and disk tools read the disk structure and the files on it fine. I have used fixparts to write a new MBR but the issue persists. I assume the issue stems from the Protective MBR data still present on the disk but I am at a loss as to how to remove it while preserving my NTFS data partition.

• Managing Database Clusters - A Whole Lot Simpler

  - by mat.keep(at)oracle.com

  Clustered computing brings with it many benefits: high performance, high availability, scalable infrastructure, etc.  But it also brings with it more complexity.Why ?  Well, by its very nature, there are more "moving parts" to monitor and manage (from physical, virtual and logical hosts) to fault detection and failover software to redundant networking components - the list goes on.  And a cluster that isn't effectively provisioned and managed will cause more downtime than the standalone systems it is designed to improve upon.  Not so great....When it comes to the database industry, analysts already estimate that 50% of a typical database's Total Cost of Ownership is attributable to staffing and downtime costs.  These costs will only increase if a database cluster is to hard to properly administer.Over the past 9 months, monitoring and management has been a major focus in the development of the MySQL Cluster database, and on Tuesday 12th January, the product team will be presenting the output of that development in a new webinar.Even if you can't make the date, it is still worth registering so you will receive automatic notification when the on-demand replay is availableIn the webinar, the team will cover:    * NDBINFO: released with MySQL Cluster 7.1, NDBINFO presents real-time status and usage statistics, providing developers and DBAs with a simple means of pro-actively monitoring and optimizing database performance and availability.    * MySQL Cluster Manager (MCM): available as part of the commercial MySQL Cluster Carrier Grade Edition, MCM simplifies the creation and management of MySQL Cluster by automating common management tasks, delivering higher administration productivity and enhancing cluster agility. Tasks that used to take 46 commands can be reduced to just one!    * MySQL Cluster Advisors & Graphs: part of the MySQL Enterprise Monitor and available in the commercial MySQL Cluster Carrier Grade Edition, the Enterprise Advisor includes automated best practice rules that alert on key performance and availability metrics from MySQL Cluster data nodes.You'll also learn how you can get started evaluating and using all of these tools to simplify MySQL Cluster management.This session will last round an hour and will include interactive Q&A throughout. You can learn more about MySQL Cluster Manager from this whitepaper and on-line demonstration.  You can also download the packages from eDelivery (just select "MySQL Database" as the product pack, select your platform, click "Go" and then scroll down to get the software).While managing clusters will never be easy, the webinar will show hou how it just got a whole lot simpler !

• Setting up a local AI server - easy with Solaris 11

  - by Stefan Hinker

  Many things are new in Solaris 11, Autoinstall is one of them.  If, like me, you've known Jumpstart for the last 2 centuries or so, you'll have to start from scratch.  Well, almost, as the concepts are similar, and it's not all that difficult.  Just new. I wanted to have an AI server that I could use for demo purposes, on the train if need be.  That answers the question of hardware requirements: portable.  But let's start at the beginning. First, you need an OS image, of course.  In the new world of Solaris 11, it is now called a repository.  The original can be downloaded from the Solaris 11 page at Oracle.   What you want is the "Oracle Solaris 11 11/11 Repository Image", which comes in two parts that can be combined using cat.  MD5 checksums for these (and all other downloads from that page) are available closer to the top of the page. With that, building the repository is quick and simple: # zfs create -o mountpoint=/export/repo rpool/ai/repo # zfs create rpool/ai/repo/s11 # mount -o ro -F hsfs /tmp/sol-11-1111-repo-full.iso /mnt # rsync -aP /mnt/repo /export/repo/s11 # umount /mnt # pkgrepo rebuild -s /export/repo/sol11/repo # zfs snapshot rpool/ai/repo/sol11@fcs # pkgrepo info -s /export/repo/sol11/repo PUBLISHER PACKAGES STATUS UPDATED solaris 4292 online 2012-03-12T20:47:15.378639Z That's all there's to it.  Let's make a snapshot, just to be on the safe side.  You never know when one will come in handy.  To use this repository, you could just add it as a file-based publisher: # pkg set-publisher -g file:///export/repo/sol11/repo solaris In case I'd want to access this repository through a (virtual) network, i'll now quickly activate the repository-service: # svccfg -s application/pkg/server \ setprop pkg/inst_root=/export/repo/sol11/repo # svccfg -s application/pkg/server setprop pkg/readonly=true # svcadm refresh application/pkg/server # svcadm enable application/pkg/server That's all you need - now point your browser to http://localhost/ to view your beautiful repository-server. Step 1 is done.  All of this, by the way, is nicely documented in the README file that's contained in the repository image. Of course, we already have updates to the original release.  You can find them in MOS in the Oracle Solaris 11 Support Repository Updates (SRU) Index.  You can simply add these to your existing repository or create separate repositories for each SRU.  The individual SRUs are self-sufficient and incremental - SRU4 includes all updates from SRU2 and SRU3.  With ZFS, you can also get both: A full repository with all updates and at the same time incremental ones up to each of the updates: # mount -o ro -F hsfs /tmp/sol-11-1111-sru4-05-incr-repo.iso /mnt # pkgrecv -s /mnt/repo -d /export/repo/sol11/repo '*' # umount /mnt # pkgrepo rebuild -s /export/repo/sol11/repo # zfs snapshot rpool/ai/repo/sol11@sru4 # zfs set snapdir=visible rpool/ai/repo/sol11 # svcadm restart svc:/application/pkg/server:default The normal repository is now updated to SRU4.  Thanks to the ZFS snapshots, there is also a valid repository of Solaris 11 11/11 without the update located at /export/repo/sol11/.zfs/snapshot/fcs . If you like, you can also create another repository service for each update, running on a separate port. But now lets continue with the AI server.  Just a little bit of reading in the dokumentation makes it clear that we will need to run a DHCP server for this.  Since I already have one active (for my SunRay installation) and since it's a good idea to have these kinds of services separate anyway, I decided to create this in a Zone.  So, let's create one first: # zfs create -o mountpoint=/export/install rpool/ai/install # zfs create -o mountpoint=/zones rpool/zones # zonecfg -z ai-server zonecfg:ai-server> create create: Using system default template 'SYSdefault' zonecfg:ai-server> set zonepath=/zones/ai-server zonecfg:ai-server> add dataset zonecfg:ai-server:dataset> set name=rpool/ai/install zonecfg:ai-server:dataset> set alias=install zonecfg:ai-server:dataset> end zonecfg:ai-server> commit zonecfg:ai-server> exit # zoneadm -z ai-server install # zoneadm -z ai-server boot ; zlogin -C ai-server Give it a hostname and IP address at first boot, and there's the Zone.  For a publisher for Solaris packages, it will be bound to the "System Publisher" from the Global Zone.  The /export/install filesystem, of course, is intended to be used by the AI server.  Let's configure it now: #zlogin ai-server root@ai-server:~# pkg install install/installadm root@ai-server:~# installadm create-service -n x86-fcs -a i386 \ -s pkg://solaris/install-image/[email protected],5.11-0.175.0.0.0.2.1482 \ -d /export/install/fcs -i 192.168.2.20 -c 3 With that, the core AI server is already done.  What happened here?  First, I installed the AI server software.  IPS makes that nice and easy.  If necessary, it'll also pull in the required DHCP-Server and anything else that might be missing.  Watch out for that DHCP server software.  In Solaris 11, there are two different versions.  There's the one you might know from Solaris 10 and earlier, and then there's a new one from ISC.  The latter is the one we need for AI.  The SMF service names of both are very similar.  The "old" one is "svc:/network/dhcp-server:default". The ISC-server comes with several SMF-services. We at least need "svc:/network/dhcp/server:ipv4".  The command "installadm create-service" creates the installation-service. It's called "x86-fcs", serves the "i386" architecture and gets its boot image from the repository of the system publisher, using version 5.11,5.11-0.175.0.0.0.2.1482, which is Solaris 11 11/11.  (The option "-a i386" in this example is optional, since the installserver itself runs on a x86 machine.) The boot-environment for clients is created in /export/install/fcs and the DHCP-server is configured for 3 IP-addresses starting at 192.168.2.20.  This configuration is stored in a very human readable form in /etc/inet/dhcpd4.conf.  An AI-service for SPARC systems could be created in the very same way, using "-a sparc" as the architecture option. Now we would be ready to register and install the first client.  It would be installed with the default "solaris-large-server" using the publisher "http://pkg.oracle.com/solaris/release" and would query it's configuration interactively at first boot.  This makes it very clear that an AI-server is really only a boot-server.  The true source of packets to install can be different.  Since I don't like these defaults for my demo setup, I did some extra config work for my clients. The configuration of a client is controlled by manifests and profiles.  The manifest controls which packets are installed and how the filesystems are layed out.  In that, it's very much like the old "rules.ok" file in Jumpstart.  Profiles contain additional configuration like root passwords, primary user account, IP addresses, keyboard layout etc.  Hence, profiles are very similar to the old sysid.cfg file. The easiest way to get your hands on a manifest is to ask the AI server we just created to give us it's default one.  Then modify that to our liking and give it back to the installserver to use: root@ai-server:~# mkdir -p /export/install/configs/manifests root@ai-server:~# cd /export/install/configs/manifests root@ai-server:~# installadm export -n x86-fcs -m orig_default \ -o orig_default.xml root@ai-server:~# cp orig_default.xml s11-fcs.small.local.xml root@ai-server:~# vi s11-fcs.small.local.xml root@ai-server:~# more s11-fcs.small.local.xml <!DOCTYPE auto_install SYSTEM "file:///usr/share/install/ai.dtd.1"> <auto_install> <ai_instance name="S11 Small fcs local"> <target> <logical> <zpool name="rpool" is_root="true"> <filesystem name="export" mountpoint="/export"/> <filesystem name="export/home"/> <be name="solaris"/> </zpool> </logical> </target> <software type="IPS"> <destination> <image> <!-- Specify locales to install --> <facet set="false">facet.locale.*</facet> <facet set="true">facet.locale.de</facet> <facet set="true">facet.locale.de_DE</facet> <facet set="true">facet.locale.en</facet> <facet set="true">facet.locale.en_US</facet> </image> </destination> <source> <publisher name="solaris"> <origin name="http://192.168.2.12/"/> </publisher> </source> <!-- By default the latest build available, in the specified IPS repository, is installed.

Use my own package service as publisher, running on IP address 192.168.2.12 Install the initial release of Solaris 11:  pkg:/[email protected],5.11-0.175.0.0.0.2.0 Using a similar approach, I'll create a default profile interactively and use it as a template for a few customized building blocks, each defining a part of the overall system configuration.  The modular approach makes it easy to configure numerous clients later on: root@ai-server:~# mkdir -p /export/install/configs/profiles root@ai-server:~# cd /export/install/configs/profiles root@ai-server:~# sysconfig create-profile -o

"mars.xml" defines network settings for an individual client.  This profile is associated with an IP-Address.  For this to work, I'll have to tweak the DHCP-settings in the next step: root@ai-server:~# installadm create-client -e 08:00:27:AA:3D:B1 -n x86-fcs root@ai-server:~# vi /etc/inet/dhcpd4.conf root@ai-server:~# tail -5 /etc/inet/dhcpd4.conf host 080027AA3DB1 { hardware ethernet 08:00:27:AA:3D:B1; fixed-address 192.168.2.100; filename "01080027AA3DB1"; } This completes the client preparations.  I manually added the IP-Address for mars to /etc/inet/dhcpd4.conf.  This is needed for the "mars.xml" profile.  Disabling arbitrary DHCP-replies will shut up this DHCP server, making my life in a shared environment a lot more peaceful ;-)Now, I of course want this installation to be completely hands-off.  For this to work, I'll need to modify the grub boot menu for this client slightly.  You can find it in /etc/netboot.  "installadm create-client" will create a new boot menu for every client, identified by the client's MAC address.  The template for this can be found in a subdirectory with the name of the install service, /etc/netboot/x86-fcs in our case.  If you don't want to change this manually for every client, modify that template to your liking instead. root@ai-server:~# cd /etc/netboot root@ai-server:~# cp menu.lst.01080027AA3DB1 menu.lst.01080027AA3DB1.org root@ai-server:~# vi menu.lst.01080027AA3DB1 root@ai-server:~# diff menu.lst.01080027AA3DB1 menu.lst.01080027AA3DB1.org 1,2c1,2 < default=1 < timeout=10 --- > default=0 > timeout=30 root@ai-server:~# more menu.lst.01080027AA3DB1 default=1 timeout=10 min_mem64=0 title Oracle Solaris 11 11/11 Text Installer and command line kernel$ /x86-fcs/platform/i86pc/kernel/$ISADIR/unix -B install_media=htt p://$serverIP:5555//export/install/fcs,install_service=x86-fcs,install_svc_addre ss=$serverIP:5555 module$ /x86-fcs/platform/i86pc/$ISADIR/boot_archive title Oracle Solaris 11 11/11 Automated Install kernel$ /x86-fcs/platform/i86pc/kernel/$ISADIR/unix -B install=true,inst all_media=http://$serverIP:5555//export/install/fcs,install_service=x86-fcs,inst all_svc_address=$serverIP:5555,livemode=text module$ /x86-fcs/platform/i86pc/$ISADIR/boot_archive Now just boot the client off the network using PXE-boot.  For my demo purposes, that's a client from VirtualBox, of course.  That's all there's to it.  And despite the fact that this blog entry is a little longer - that wasn't that hard now, was it?

• The Sitemap Paradox

  - by Jeff Atwood

  We use a sitemap on Stack Overflow, but I have mixed feelings about it. Web crawlers usually discover pages from links within the site and from other sites. Sitemaps supplement this data to allow crawlers that support Sitemaps to pick up all URLs in the Sitemap and learn about those URLs using the associated metadata. Using the Sitemap protocol does not guarantee that web pages are included in search engines, but provides hints for web crawlers to do a better job of crawling your site. Based on our two years' experience with sitemaps, there's something fundamentally paradoxical about the sitemap: Sitemaps are intended for sites that are hard to crawl properly. If Google can't successfully crawl your site to find a link, but is able to find it in the sitemap it gives the sitemap link no weight and will not index it! That's the sitemap paradox -- if your site isn't being properly crawled (for whatever reason), using a sitemap will not help you! Google goes out of their way to make no sitemap guarantees: "We cannot make any predictions or guarantees about when or if your URLs will be crawled or added to our index" citation "We don't guarantee that we'll crawl or index all of your URLs. For example, we won't crawl or index image URLs contained in your Sitemap." citation "submitting a Sitemap doesn't guarantee that all pages of your site will be crawled or included in our search results" citation Given that links found in sitemaps are merely recommendations, whereas links found on your own website proper are considered canonical ... it seems the only logical thing to do is avoid having a sitemap and make damn sure that Google and any other search engine can properly spider your site using the plain old standard web pages everyone else sees. By the time you have done that, and are getting spidered nice and thoroughly so Google can see that your own site links to these pages, and would be willing to crawl the links -- uh, why do we need a sitemap, again? The sitemap can be actively harmful, because it distracts you from ensuring that search engine spiders are able to successfully crawl your whole site. "Oh, it doesn't matter if the crawler can see it, we'll just slap those links in the sitemap!" Reality is quite the opposite in our experience. That seems more than a little ironic considering sitemaps were intended for sites that have a very deep collection of links or complex UI that may be hard to spider. In our experience, the sitemap does not help, because if Google can't find the link on your site proper, it won't index it from the sitemap anyway. We've seen this proven time and time again with Stack Overflow questions. Am I wrong? Do sitemaps make sense, and we're somehow just using them incorrectly?

• Welcome to my geeks blog

  - by bconlon

  Hi and welcome! I'm Bazza and this is my geeks blog. I have 20 years Visual Studio mainly C++, MFC,  ATL and now, thankfully, C# and I am embarking on the new world (well new to me) of WPF, so I thought I would try and capture my successful...and not so successful...WPF experiences with the geek world. So where to start? WPF? What I know so far... From wiki..."Windows Presentation Foundation (or WPF) is a graphical subsystem for rendering user interfaces in Windows-based applications." Hmm, great but didn't MFC, ATL (my head hurt with that one), and .Net all have APIs to allow me to code against the Windows Graphical Device Interface (GDI)? "Rather than relying on the older GDI subsystem, WPF utilizes DirectX. WPF attempts to provide a consistent programming model for building applications and provides a separation between the user interface and the business logic." OK, different drawing code, same Windows and weren't we always taught to separate our UI, Business Layer and Data Access Layer? "WPF employs XAML, a derivative of XML, to define and link various UI elements. WPF applications can be deployed as standalone desktop programs, or hosted as an embedded object in a website." Cool, now we're getting somewhere. So when they say separation they really mean separation. The crux of this appears to be that you can have creative people writing the UI and making it attractive and intuitive to use, whist the geeks concentrate on writing the Business and Data Access stuff. XAML (eXtensible Application Markup Language) maps XML elements and attributes directly to Common Language Runtime (CLR) object instances, properties and events. True separation of the View and Model. WPF also provides logical separation of a control from its appearance. In a traditional Windows system, all Controls have a base class containing a Windows handle and each Control knows how to render itself. In WPF, the controls are more like those in a Web Browser using Cascading Style Sheet, they are not wrappers for standard Windows Controls. Instead, they have a default 'template' that defines a visual theme which can easily be replaced by a custom template. But it gets better. WPF concentrates heavily on Data Binding where the client can bind directly to data on the server. I think this concept was first introduced in 'Classic' Visual Basic, where you could bind a list directly to a data from an Access database, and you could do similar in ASP .Net. However, the WPF implementation is far superior than it's predecessors. There are also other technologies that I want to look at like LINQ and the Entity Framework, but that's all for now. #

• MacBook Pro Late 2009 SATA Resets, Slowness

  - by A Student at a University

  My MacBook Pro runs slower the longer it's on. I am getting kernel warnings. The resets correlate with AC power connects and disconnects. I don't know if the warnings do. (How do I tell?) Are these bus CRC errors? Or something else? Can this damage the drive or corrupt data? What is it seeing that motivates these? 02:37:16 :[ 0.791992] ahci 0000:00:0b.0: PCI INT A -> Link[LSI0] -> GSI 20 (level, low) -> IRQ 20 02:37:16 :[ 0.792053] ahci 0000:00:0b.0: controller can't do PMP, turning off CAP_PMP 02:37:16 :[ 0.792104] ahci 0000:00:0b.0: AHCI 0001.0200 32 slots 6 ports 1.5 Gbps 0x3 impl IDE mode 02:37:16 :[ 0.792107] ahci 0000:00:0b.0: flags: 64bit ncq sntf pm led pio slum part boh 02:37:16 :[ 0.813473] scsi0 : ahci 02:37:16 :[ 0.823340] scsi1 : ahci 02:37:16 :[ 0.848164] ata1: SATA max UDMA/133 abar m8192@0xe7484000 port 0xe7484100 irq 43 02:37:16 :[ 0.848166] ata2: SATA max UDMA/133 abar m8192@0xe7484000 port 0xe7484180 irq 43 02:37:16 :[ 1.190132] ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) 02:37:16 :[ 1.190153] ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300) 02:37:16 :[ 1.213568] ata1.00: ATA-8: OCZ-VERTEX2, 1.23, max UDMA/133 02:37:16 :[ 1.213572] ata1.00: 195371568 sectors, multi 1: LBA48 NCQ (depth 31/32) 02:37:16 :[ 1.227293] ata2.00: ATA-8: ST9500420ASG, 0002SDM1, max UDMA/133 02:37:16 :[ 1.227297] ata2.00: 976773168 sectors, multi 16: LBA48 NCQ (depth 31/32) 02:37:16 :[ 1.229570] ata2.00: configured for UDMA/133 02:37:16 :[ 1.240133] ata2: hard resetting link 02:37:16 :[ 1.260738] ata1.00: configured for UDMA/133 02:37:16 :[ 1.280122] ata1: hard resetting link 02:37:16 :[ 1.470125] usb 2-5: new high speed USB device using ehci_hcd and address 3 02:37:16 :[ 1.550165] firewire_core: created device fw0: GUID 58b035fffea99f5c, S800 02:37:16 :[ 1.631306] Initializing USB Mass Storage driver... 02:37:16 :[ 1.631392] scsi6 : usb-storage 2-5:1.0 02:37:16 :[ 1.631454] usbcore: registered new interface driver usb-storage 02:37:16 :[ 1.631455] USB Mass Storage support registered. 02:37:16 :[ 1.960128] usb 4-1: new full speed USB device using ohci_hcd and address 2 02:37:16 :[ 1.990101] ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300) 02:37:16 :[ 1.994215] ata2.00: configured for UDMA/133 02:37:16 :[ 1.994220] ata2: EH complete 02:37:16 :[ 2.030097] ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) 02:37:16 :[ 2.090773] ata1.00: configured for UDMA/133 02:37:16 :[ 2.090778] ata1: EH complete 02:37:16 :[ 2.090931] scsi 0:0:0:0: Direct-Access ATA OCZ-VERTEX2 1.23 PQ: 0 ANSI: 5 02:37:16 :[ 2.091045] sd 0:0:0:0: Attached scsi generic sg0 type 0 02:37:16 :[ 2.091121] sd 0:0:0:0: [sda] 195371568 512-byte logical blocks: (100 GB/93.1 GiB) 02:37:16 :[ 2.091159] scsi 1:0:0:0: Direct-Access ATA ST9500420ASG 0002 PQ: 0 ANSI: 5 02:37:16 :[ 2.091163] sd 0:0:0:0: [sda] Write Protect is off 02:37:16 :[ 2.091183] sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA 02:37:16 :[ 2.091252] sd 1:0:0:0: Attached scsi generic sg1 type 0 02:37:16 :[ 2.091337] sda: 02:37:16 :[ 2.091446] sd 1:0:0:0: [sdb] 976773168 512-byte logical blocks: (500 GB/465 GiB) 02:37:16 :[ 2.091580] sd 1:0:0:0: [sdb] Write Protect is off 02:37:16 :[ 2.091637] sd 1:0:0:0: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA 02:37:16 :[ 2.091756] sdb: sda1 sda2 02:37:16 :[ 2.093140] sd 0:0:0:0: [sda] Attached SCSI disk 02:37:16 :[ 2.093505] sdb1 sdb2 sdb3 02:37:16 :[ 2.093773] sd 1:0:0:0: [sdb] Attached SCSI disk 02:37:16 :[ 2.693899] EXT4-fs (dm-0): mounted filesystem with ordered data mode.

• 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.

• How to (un)dock IBM Thinkpad X41 from X4 Dock(ing station) successfully?

  - by nutty about natty

  I'd like to start using my docking station again; however, it still doesn't work as it should, see the following bug descriptions (with special focus on Thinkpad X41 & the X4 Dock). Given that it still doesn't work (effective April 2012), my hope is fading that it will start working all of a sudden with Precise Pangolin at the end of the month. This issue is VERY important to me and I would be MOST grateful to anyone being able to sieve through the following links (some of which are actually quite recent) and translate their meaning into reliable and concrete simple (?) steps. I've read briefly about hal and udev, and can imagine that they are somewhat related to this, see links below. I don't want to fire at random. I don't want to tinker around with bash scripts if avoidable... Problem description (more or less ;-) Pressing the undock button on a "ThinkPad X4 Dock" with a ThinkPad X40 does not cause any udev events. And the lights on the dock never change to indicate it is safe to undock. and IBM Thinkpad X41 & docking station no joy :-( ... when pressing the blue undock button on the docking station: - The screen goes blank (with backlight remaining on), - with some SSD/HDD activity; - ctrl alt del causes a shut down after ... seconds, indicating that the system itself hasn't "crashed" but is still (somewhat ?) responsive. and With recent distributions, docking and undocking should function out of the box. You can monitor this by running # udevadm monitor and when you dock or press the undock button you should see a flurry of events. There are some issues though: No event on undock. - In some cases you may not get any events on undock. This is due to the ACPI dock drivers only registering the first logical Dock port they encounter and in some rare cases there may be more then one, such as on a ThinkPad X40 with ThinkPad X4 Dock. Patches are available, and are merged in 2.6.34. Now, if patches are available and merged into 2.6.34 - why isn't (un)docking simply working / fully supported in the latest version of Natty (which to my humble understanding has surpassed kernel version 2.6.34 a while ago)? More relevant links: ThinkPad X41 Docking Station issues and [HOWTO] Run scripts for laptop lid open/close and dock/undock events and finally Symptoms corrected by the latest BIOS Update - ThinkPad X41 - (Fix) USB devices connected to UltraBase X4 or ThinkPad X4 Dock may not be recognized in Boot Menu by pressing F12 during POST. Thanks!!

• SQL Developer Data Modeler: On Notes, Comments, and Comments in RDBMS

  - by thatjeffsmith

  Ah the beautiful data model. They say a picture is worth a 1,000 words. And then we have our diagrams, how many words are they worth? Our friends from the Human Relations sample schema So our models describe how the data ‘works’ – whether that be at a logical-business level, or a technical-physical level. Developers like to say that their code is self-documenting. These would be very lazy or very bad (or both) developers. Models are the same way, you should document your models with comments and notes! I have 3 basic options: Comments Comments in RDBMS Notes So what’s the difference? Comments You’re describing the entity/table or attribute/column. This information will NOT be published in the database. It will only be available to the model, and hence, folks with access to the model. Table Comments (in the design only!) Comments in RDBMS You’re doing the same thing as above, but your words will be stored IN the data dictionary of the database. Oracle allows you to store comments on the table and column definitions. So your awesome documentation is going to be viewable to anyone with access to the database. RDBMS is an acronym for Relational Database Management System – of which Oracle is one of the first commercial examples If the DDL is produced and ran against a database, these comments WILL be stored in the data dictionary. Notes A place for you to add notes, maybe from a design meeting. Or maybe you’re using this as a to-do or requirements list. Basically it’s for anything that doesn’t literally describe the object at hand – that’s what the comments are for. I totally made these up. Now these are free text fields and you can put whatever you want here. Just make sure you put stuff here that’s worth reading. And it will live on…forever.

• Autoscaling in a modern world&hellip;. Part 3

  The Wasabi Hands on Labs give you a good look at the basic mechanics, but I don’t find the setup too practical.  Using a local console application to host the Autoscaler and rules files is probably the (IMHO) least likely architecture.  Far more common would be hosting in a service on premise (if you want to have the Autoscaler local) or most likely, host it in a Azure role of it’s own.  I chose to go the Azure route. First step was to get the rules.xml and the services.xml files into the cloud.  I tend to be a “one step at a time” sort of guy, so running the console application with the rules sitting in a Azure hosted set of blobs seemed to be the logical first step.  Here are the steps: 1) Create a container in the storage account you wish to use.  Name does not matter, you will get a chance to set the container name (as well as the file names) in the app.config 2) Copy the two files from where you created them to your  container.  I used the same files I had locally.  I made the container public to eliminate security issues, but in the final application, a bit of security needs to be applied (one problem at a time).  The content type was set to text/xml.  I found one reference claiming the importance of this step, and it makes sense. 3) Adjust the app.config to set the location of the files.  This will let you set all the storage account and key information needed to reach into the cloud form your console application.  The sections of your app.config will look like this: <rulesStores> <add name="Blob Rules Store" type="Microsoft.Practices.EnterpriseLibrary.WindowsAzure.Autoscaling.Rules.Configuration.BlobXmlFileRulesStore, Microsoft.Practices.EnterpriseLibrary.WindowsAzure.Autoscaling, Version=5.0.1118.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" blobContainerName="[ContainerName]" blobName="rules.xml" storageAccount="DefaultEndpointsProtocol=https;AccountName=[StorageAccount];AccountKey=[AccountKey]" monitoringRate="00:00:30" certificateThumbprint="" certificateStoreLocation="LocalMachine" checkCertificateValidity="false" /> </rulesStores> <serviceInformationStores> <add name="Blob Service Information Store" type="Microsoft.Practices.EnterpriseLibrary.WindowsAzure.Autoscaling.ServiceModel.Configuration.BlobXmlFileServiceInformationStore, Microsoft.Practices.EnterpriseLibrary.WindowsAzure.Autoscaling, Version=5.0.1118.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" blobContainerName="[ContainerName]" blobName="services.xml" storageAccount="DefaultEndpointsProtocol=https;AccountName=[StorageAccount];AccountKey=[AccountKey]" monitoringRate="00:00:30" certificateThumbprint="" certificateStoreLocation="LocalMachine" checkCertificateValidity="false" /> </serviceInformationStores> Once I had the files up in the sky, I renamed the local copies to just to make my self feel better about the application using the correct set of rules and services.  Deploy the web role to the cloud.  Once it is up and running, start the console application.  You should find the application scales up and down in response to the buttons on the web site.  Tune in next time for moving the hosting of the Autoscaler to a worker role, discussions on getting the logging information into diagnostics into storage, and a set of discussions about certs and how they play a role.

• Plan Operator Tuesday round-up

  - by Rob Farley

  Eighteen posts for T-SQL Tuesday #43 this month, discussing Plan Operators. I put them together and made the following clickable plan. It’s 1000px wide, so I hope you have a monitor wide enough. Let me explain this plan for you (people’s names are the links to the articles on their blogs – the same links as in the plan above). It was clearly a SELECT statement. Wayne Sheffield (@dbawayne) wrote about that, so we start with a SELECT physical operator, leveraging the logical operator Wayne Sheffield. The SELECT operator calls the Paul White operator, discussed by Jason Brimhall (@sqlrnnr) in his post. The Paul White operator is quite remarkable, and can consume three streams of data. Let’s look at those streams. The first pulls data from a Table Scan – Boris Hristov (@borishristov)’s post – using parallel threads (Bradley Ball – @sqlballs) that pull the data eagerly through a Table Spool (Oliver Asmus – @oliverasmus). A scalar operation is also performed on it, thanks to Jeffrey Verheul (@devjef)’s Compute Scalar operator. The second stream of data applies Evil (I figured that must mean a procedural TVF, but could’ve been anything), courtesy of Jason Strate (@stratesql). It performs this Evil on the merging of parallel streams (Steve Jones – @way0utwest), which suck data out of a Switch (Paul White – @sql_kiwi). This Switch operator is consuming data from up to four lookups, thanks to Kalen Delaney (@sqlqueen), Rick Krueger (@dataogre), Mickey Stuewe (@sqlmickey) and Kathi Kellenberger (@auntkathi). Unfortunately Kathi’s name is a bit long and has been truncated, just like in real plans. The last stream performs a join of two others via a Nested Loop (Matan Yungman – @matanyungman). One pulls data from a Spool (my post – @rob_farley) populated from a Table Scan (Jon Morisi). The other applies a catchall operator (the catchall is because Tamera Clark (@tameraclark) didn’t specify any particular operator, and a catchall is what gets shown when SSMS doesn’t know what to show. Surprisingly, it’s showing the yellow one, which is about cursors. Hopefully that’s not what Tamera planned, but anyway...) to the output from an Index Seek operator (Sebastian Meine – @sqlity). Lastly, I think everyone put in 110% effort, so that’s what all the operators cost. That didn’t leave anything for me, unfortunately, but that’s okay. Also, because he decided to use the Paul White operator, Jason Brimhall gets 0%, and his 110% was given to Paul’s Switch operator post. I hope you’ve enjoyed this T-SQL Tuesday, and have learned something extra about Plan Operators. Keep your eye out for next month’s one by watching the Twitter Hashtag #tsql2sday, and why not contribute a post to the party? Big thanks to Adam Machanic as usual for starting all this. @rob_farley

• Dual booting 12.10 and Win 7 - boots directly to Win 7

  - by user110174

  and thank you kindly for you help! I'll preface this with saying that I realize this is a common problem, with lots of trouble-shooting guides available online; however, after multiple attempts with different guides, I've made zero progress and am hoping to someone could help me with my specific scenario. First, my story: -Initially, I installed Ubuntu 12.10 with the "Something Else" option with no problems. Used 4 GB Swap Logical Partition, 26 GB Primary Root Partition. Wanting to trying out Mint 13, I booted into Windows from GRUB2, used the latest version of EasyBCD (v2.2) to restore the Windows 7 bootloader to the MBR, deleted the Ubuntu partitions, reformatted them in NTFS. I then created a 30 GB partition of free space for Mint. I installed Mint using the same partitioning described above for Ubuntu 12.10, using /dev/sda for the boot installation files, and everything seemed to go well, until I re-booted my computer and it went straight to Windows - I could find no way to get into Mint. So I went into windows, restored windows bootloader to the MBR w/ EasyBCD, deleted partitions, etc., as I figured I'd done enough messing around and would go with Ubuntu 12.10. Now the problem: I restarted my computer booting from the same Ubuntu USB key I originally used. Briefly, "error: "prefix" is not set" flashed on screen, and instead of being greeted with the GUI menu of "try vs. install Ubuntu", there was a menu with minimal graphics (like a BIOS menu) where I could select install, run from USB, etc. After selecting "Install Ubuntu", the familiar install wizard with a GUI came up, I partitioned my drive as described, /dev/sda for the boot installation files, install went well, rebooted and...straight to Windows. This is where I'm at. Fixes I've tried: -This guide: How can I repair grub? (How to get Ubuntu back after installing Windows?) to ensure Grub is on the MBR. I followed all steps, but still when I reboot, I go directly into Windows. -Installing 12.04 instead of 12.10 - same issue -Re-installed Ubuntu, writing the boot files to their own partition, then using EasyBCD to to add a boot option for Ubuntu using the Windows bootloader, ensuring I instruct EasyBCD to look at the partition I created with the Ubuntu installer (instructions here http://neosmart.net/wiki/display/EBCD/Ubuntu). When I reboot, I select the Ubuntu option, and it puts me in GRUB4DOS, with a cursor waiting for input. I have no idea what to put here, so I would just type "reboot" to exit out. And this is where I am now. Any clue as to why I can't boot into Ubuntu? My computer specs are: ASUS UX31A Core i7, Win 7 64 Pro, 256 GB SSD, Intel HM76 Chipset and Integrated Intel HD 4000 Graphics, 4 GB memory I've tried to be as clear as possible, but I'd be happy to provide any info that would help anyone along. Thanks for your patience in reading this! Sincerely, -MN

• Oracle Releases New Mainframe Re-Hosting in Oracle Tuxedo 11g

  - by Jason Williamson

  I'm excited to say that we've released our next generation of Re-hosting in 11g. In fact I'm doing some hands-on labs now for our Systems Integrators in Italy in a couple of weeks and targeting Latin America next month. If you are an SI, or Rehosting firm and are looking to become an Oracle Partner or get a better understanding of Tuxedo and how to use the workbench for rehosting...drop me a line. Oracle Tuxedo Application Runtime for CICS and Batch 11g provides a CICS API emulation and Batch environment that exploits the full range of Oracle Tuxedo's capabilities. Re-hosted applications run in a multi-node, grid environment with centralized production control. Also, enterprise integration of CICS application services benefits from an open and SOA-enabled framework. Key features include: CICS Application Runtime: Can run IBM CICS applications unchanged in an application grid, which enables the distribution of large workloads across multiple processors and nodes. This simplifies CICS administration and can scale to over 100,000 users and over 50,000 transactions per second. 3270 Terminal Server: Protects business users from change through support for tn3270 terminal emulation. Distributed CICS Resource Management: Simplifies deployment and administration by allowing customers to run CICS regions in a distributed configuration. Batch Application Runtime: Provides robust IBM JES-like job management that enables local or remote job submissions. In addition, distributed batch initiators can enable parallelization of jobs and support fail-over, shortening the batch window and helping to meet stringent SLAs. Batch Execution Environment: Helps to run IBM batch unchanged and also supports JCL functionality and all common batch utilities. Oracle Tuxedo Application Rehosting Workbench 11g provides a set of automated migration tools integrated around a central repository. The tools provide high precision which results in very low error rates and the ability to handle large applications. This enables less expensive, low-risk migration projects. Key capabilities include: Workbench Repository and Cataloguer: Ensures integrity of the migrated application assets through full dependency checking. The Cataloguer generates and maintains all relevant meta-data on source and target components. File Migrator: Supports reliable migration of datasets and flat files to an ISAM or Oracle Database 11g. This is done through the automated migration utilities for data unloading, reloading and validation. It also generates logical access functions to shield developers from data repository changes. DB2 Migrator: Similarly, this tool automates the migration of DB2 schema and data to Oracle Database 11g. COBOL Migrator: Supports migration of IBM mainframe COBOL assets (OLTP and Batch) to open systems. Adapts programs for compiler dialects and data access variations. JCL Migrator: Supports migration of IBM JCL jobs to a Tuxedo ART environment, maintaining the flow and characteristics of batch jobs.

• Sony VAIO with Insyde H2O EFI bios will not boot into GRUB EFI

  - by Rohan Dhruva

  I bought a new Sony Vaio S series laptop. It uses Insyde H2O BIOS EFI, and trying to install Linux on it is driving me crazy. root@kubuntu:~# parted /dev/sda print Model: ATA Hitachi HTS72756 (scsi) Disk /dev/sda: 640GB Sector size (logical/physical): 512B/4096B Partition Table: gpt Number Start End Size File system Name Flags 1 1049kB 274MB 273MB fat32 EFI system partition hidden 2 274MB 20.8GB 20.6GB ntfs Basic data partition hidden, diag 3 20.8GB 21.1GB 273MB fat32 EFI system partition boot 4 21.1GB 21.3GB 134MB Microsoft reserved partition msftres 5 21.3GB 342GB 320GB ntfs Basic data partition 6 342GB 358GB 16.1GB ext4 Basic data partition 7 358GB 374GB 16.1GB ntfs Basic data partition 8 374GB 640GB 266GB ntfs Basic data partition What is surprising is that there are 2 EFI system partitions on the disk. The sda2 partition is a 20gb recovery partition which loads windows with a basic recovery interface. This is accessible by pressing the "ASSIST" button as opposed to the normal power button. I presume that the sda1 EFI System Partition (ESP) loads into this recovery. The sda3 ESP has more fleshed out entries for Microsoft Windows, which actually goes into Windows 7 (as confirmed by bcdedit.exe on Windows). Ubuntu is installed on sda6, and while installation I chose sda3 as my boot partition. The installer correctly created a sda3/EFI/ubuntu/grubx64.efi application. The real problem: for the life of me, I can't set it to be the default! I tried creating a sda3/startup.nsh which called grubx64.efi, but it didn't help -- on rebooting, the system still boots into windows. I tried using efibootmgr, and that shows as it it worked: root@kubuntu:~# efibootmgr BootCurrent: 0000 BootOrder: 0000,0001 Boot0000* EFI USB Device Boot0001* Windows Boot Manager root@kubuntu:~# efibootmgr --create --gpt --disk /dev/sda --part 3 --write-signature --label "GRUB2" --loader "\\EFI\\ubuntu\\grubx64.efi" BootCurrent: 0000 BootOrder: 0002,0000,0001 Boot0000* EFI USB Device Boot0001* Windows Boot Manager Boot0002* GRUB2 root@kubuntu:~# efibootmgr BootCurrent: 0000 BootOrder: 0002,0000,0001 Boot0000* EFI USB Device Boot0001* Windows Boot Manager Boot0002* GRUB2 However, on rebooting, as you guessed, the machine rebooted directly back into Windows. The only things I can think of are: The sda1 partition is somehow being used Overwrite /EFI/Boot/bootx64.efi and /EFI/Microsoft/Boot/bootmgfw.efi with grubx64.efi [but this seems really radical]. Can anyone please help me out? Thanks -- any help is greatly appreciated, as this issue is driving me crazy!
