  • 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.

  • Sesame update du jour: SL 4, OOB, Azure, and proxy support

    - by Fabrice Marguerie
    I've just published a new version of Sesame Data Browser. Here's what's new this time: Upgraded to Silverlight 4 Can run out-of-browser (OOB), with elevated permissions. This gives you an icon on your desktop and enables new scenarios. Note: The application is unsigned for the moment. Support for Windows Azure authentication Support for SQL Azure authentication If you are behind a proxy that requires authentication, just give Sesame a new try after clicking on "If you are behind a proxy that requires authentication, please click here" An icon and a button for closing connections are now displayed on connection tabsSome less visible improvements Here is the connection view with anonymous access: If you want to access Windows Azure tables as OData, all you have to do is use your table storage endpoint as the URL, and provide your access key: A Windows Azure table storage address looks like this: http://<your account>.table.core.windows.net/ If you want to browse your SQL Azure databases with Sesame, you have to enable OData support for them at https://www.sqlazurelabs.com/ConfigOData.aspx. I won't show how it works because it's already been done in several places over the Web. Here are pointers: OData.org: Got SQL Azure? Then you've got OData OakLeaf Systems: Enabling and Using the OData Protocol with SQL Azure Patrick Verbruggen: Creating an OData feed for your Azure databases Shawn Wildermuth: SQL Azure's OData Support Jack Greenfield: How to Use OData for SQL Azure with AppFabric Access Control You can choose to enable anonymous access or not. When you don't enable anonymous access, you have to provide an Issuer name and a Secret key, and optionally an Security Token Service (STS) endpoint: Excerpt from Jack Greenfield's blog: To enable OData access to the currently selected database, check the box labeled "Enable OData". When OData access is enabled, database user mapping information is displayed at the bottom of the form.Use the drop down list labeled "Anonymous Access User" to select an anonymous access user. If an anonymous access user is selected, then all queries against the database presented without credentials will execute by impersonating that user. You can access the database as the anonymous user by clicking on the link provided at the bottom of the page. If no anonymous access user is selected, then the OData Service will not allow anonymous access to the database.Click the link labeled "Add User" to add a user for authenticated access. In the pop up panel, select the user from the drop down list. Leave the issuer name empty for simple authentication, or provide the name of a trusted Security Token Service (STS) for federated authentication. For example, to federate with another ACS based STS, provide the base URI for the STS endpoint displayed by the Windows Azure AppFabric Portal for the STS.Click the "OK" button to complete the configuration process and dismiss the pop up panel. When one or more authenticated access users are added, the OData Service will impersonate them when appropriate credentials are presented. You can designate as many authenticated access users as you like. The OData Service will decide which one to impersonate for each query by inspecting the credentials presented with the query.Next time I'll give an overview of how Sesame Data Browser is built.In the meantime, happy data browsing!

  • Backup Azure Tables, schedule Azure scripts&hellip; and more

    - by Herve Roggero
    Well – months of effort are now officially over… or should I say it’s just the beginning?   Enzo Cloud Backup 2.0 (beta) is now officially out!!! This tool will let you do the following: * Backup SQL Database (and SQL Server to a limited extend) * Backup Azure Tables * Restore SQL Backups into another SQL environment * Restore Azure Tables in Azure Storage, or SQL Environment * Manage and schedule database maintenance scripts * Drop database schema containers (with preview) for SaaS environments * Receive alerts (SMTP) when operations complete or fail That’s it at a high level… but you need to see the flexibility around these features. For example you can select a specific backup strategy for Azure Tables allowing faster backup operations when partition keys use GUIDs. You can also call custom stored procedures during the restore operation of Azure Tables, allowing you to transform the data along the way. You can also set a performance threshold during Azure Table backup operations to help you control possible throttling conditions in your Storage Account. Regarding database scripts, you can now define T-SQL scripts and schedule them for execution in a specific order. You can also tell Enzo to execute a pre and post script during Azure Table restore operations against a SQL environment. The backup operation now supports backing up to multiple devices at the same time. So you can execute a backup request to both a local file, and a blob at the same time, guaranteeing that both will contain the exact same data. And due to the level of options that are available, you can save backup definitions for later reuse. The screenshot below backs up Azure Tables to two devices (a blob and a SQL Database). You can also manage your database schemas for SaaS environments that use schema containers to separate customer data. This new edition allows you to see how many objects you have in each schema, backup specific schemas, and even drop all objects in a given schema. For example the screenshot below shows that the EnzoLog database has 4 user-defined schemas, and the AFA schema has 5 tables and 1 module (stored proc, function, view…). Selecting the AFA schema and trying to delete it will prompt another screen to show which objects will be deleted. As you can see, Enzo Cloud Backup provides amazing capabilities that can help you safeguard your data in SQL Database and Azure Tables, and give you advanced management functions for your Azure environment.

  • Silverlight for Everyone!!

    - by subodhnpushpak
    Someone asked me to compare Silverlight / HTML development. I realized that the question can be answered in many ways: Below is the high level comparison between a HTML /JavaScript client and Silverlight client and why silverlight was chosen over HTML / JavaScript client (based on type of users and major functionalities provided): 1. For end users Browser compatibility Silverlight is a plug-in and requires installation first. However, it does provides consistent look and feel across all browsers. For HTML / DHTML, there is a need to tweak JavaScript for each of the browser supported. In fact, tags like <span> and <div> works differently on different browser / version. So, HTML works on most of the systems but also requires lot of efforts coding-wise to adhere to all standards/ browsers / versions. Out of browser support No support in HTML. Third party tools like  Google gears offers some functionalities but there are lots of issues around platform and accessibility. Out of box support for out-of-browser support. provides features like drag and drop onto application surface. Cut and copy paste in HTML HTML is displayed in browser; which, in turn provides facilities for cut copy and paste. Silverlight (specially 4) provides rich features for cut-copy-paste along with full control over what can be cut copy pasted by end users and .advanced features like visual tree printing. Rich user experience HTML can provide some rich experience by use of some JavaScript libraries like JQuery. However, extensive use of JavaScript combined with various versions of browsers and the supported JavaScript makes the solution cumbersome. Silverlight is meant for RIA experience. User data storage on client end In HTML only small amount of data can be stored that too in cookies. In Silverlight large data may be stored, that too in secure way. This increases the response time. Post back In HTML / JavaScript the post back can be stopped by use of AJAX. Extensive use of AJAX can be a bottleneck as browser stack is used for the calls. Both look and feel and data travel over network.                           In Silverlight everything run the client side. Calls are made to server ONLY for data; which also reduces network traffic in long run. 2. For Developers Coding effort HTML / JavaScript can take considerable amount to code if features (requirements) are rich. For AJAX like interfaces; knowledge of third party kits like DOJO / Yahoo UI / JQuery is required which has steep learning curve. ASP .Net coding world revolves mostly along <table> tags for alignments whereas most popular tools provide <div> tags; which requires lots of tweaking. AJAX calls can be a bottlenecks for performance, if the calls are many. In Silverlight; coding is in C#, which is managed code. XAML is also very intuitive and Blend can be used to provide look and feel. Event handling is much clean than in JavaScript. Provides for many clean patterns like MVVM and composable application. Each call to server is asynchronous in silverlight. AJAX is in built into silverlight. Threading can be done at the client side itself to provide for better responsiveness; etc. Debugging Debugging in HTML / JavaScript is difficult. As JavaScript is interpreted; there is NO compile time error handling. Debugging in Silverlight is very helpful. As it is compiled; it provides rich features for both compile time and run time error handling. Multi -targeting browsers HTML / JavaScript have different rendering behaviours in different browsers / and their versions. JavaScript have to be written to sublime the differences in browser behaviours. Silverlight works exactly the same in all browsers and works on almost all popular browser. Multi-targeting desktop No support in HTML / JavaScript Silverlight is very close to WPF. Bot the platform may be easily targeted while maintaining the same source code. Rich toolkit HTML /JavaScript have limited toolkit as controls Silverlight provides a rich set of controls including graphs, audio, video, layout, etc. 3. For Architects Design Patterns Silverlight provides for patterns like MVVM (MVC) and rich (fat)  client architecture. This segregates the "separation of concern" very clearly. Client (silverlight) does what it is expected to do and server does what it is expected of. In HTML / JavaScript world most of the processing is done on the server side. Extensibility Silverlight provides great deal of extensibility as custom controls may be made. Extensibility is NOT restricted by browser but by the plug-in silverlight runs in. HTML / JavaScript works in a certain way and extensibility is generally done on the server side rather than client end. Client side is restricted by the limitations of the browser. Performance Silverlight provides localized storage which may be used for cached data storage. this reduces the response time. As processing can be done on client side itself; there is no need for server round trips. this decreases the round about time. Look and feel of the application is downloaded ONLY initially, afterwards ONLY data is fetched form the server. Security Silverlight is compiled code downloaded as .XAP; As compared to HTML / JavaScript, it provides more secure sandboxed approach. Cross - scripting is inherently prohibited in silverlight by default. If proper guidelines are followed silverlight provides much robust security mechanism as against HTML / JavaScript world. For example; knowing server Address in obfuscated JavaScript is easier than a compressed compiled obfuscated silverlight .XAP file. Some of these like (offline and Canvas support) will be available in HTML5. However, the timelines are not encouraging at all. According to Ian Hickson, editor of the HTML5 specification, the specification to reach the W3C Candidate Recommendation stage during 2012, and W3C Recommendation in the year 2022 or later. see http://en.wikipedia.org/wiki/HTML5 for details. The above is MY opinion. I will love to hear yours; do let me know via comments. Technorati Tags: Silverlight

  • Ha a hutés nem elég a gépteremben: Sun Cooling Door a Database Machine-hoz

    - by Fekete Zoltán
    A Database Machine hatalmas teljesítménye miatt általában jóval kevesebb hutésre van szükség, mintha egy külön high-end servert és külön high-end storage-ot hutenénk! Ha viszont a géptermünk maradék hutési kapacitása nem elegendo, és nem elégszünk meg a "hagyományos mosóporral", akkor újabb hutési trükkre van szükség. Erre kínálnak megoldást a Sun Cooling Door modellek, például az 5200-as és az 5600-as modellek.

  • Uploading to my local server is slower than downloading from the Internet

    - by Olivier Lalonde
    I have a home Ubuntu server that I use for storage. I have mounted a sftp share on my laptop to access my server but the upload speed I get is very slow (~400kb/s) compared to speeds I usually get when downloading through Bittorrent (~800kb/s). It's kind of weird... I should get higher speeds on a LAN than on the Internet... How can I speed up uploads to my server and how can I troubleshoot where the bottleneck is?

  • Clustering for Mere Mortals (Pt 3)

    - by Geoff N. Hiten
    The Controller Now we get to the meat of the matter.  You want a virtual cluster, the first thing you have to do is create your own portable domain.  Start with a plain vanilla install of Windows 2003 R2 Standard on a semi-default VM. (1 GB RAM, 2 cores, 2 NICs, 128GB dynamically expanding VHD file).  I chose this because it had the smallest disk and memory footprint of any current supported Microsoft Server product.  I created the VM with a single dynamically expanding VHD, one fixed 16 GB VHD, and two NICs.  One NIC is connected to the outside world and the other one is part of an internal-only network.  The first NIC is set up as a DHCP client.  We will get to the other one later. I actually tried this with Windows 2008 R2, but it failed miserably.  Not sure whether it was 2008 R2 or the fact I tried to use cloned VMs in the cluster.  Clustering is one place where NewSID would really come in handy.  Too bad Microsoft bought and buried it. Load and Patch the OS (hence the need for the outside connection).This is a good time to go get dinner.  Maybe a movie too.  There are close to a hundred patches that need to be downloaded and applied.  Avoiding that mess was why I put so much time into trying to get the 2008 R2 version working.  Maybe next time.  Don’t forget to add the extensions for VMLite (or whatever virtualization product you prefer). Set a fixed IP address on the internal-only NIC.  Do not give it a gateway.  Put the same IP address for the NIC and for the DNS Server.  This IP should be in a range that is never available on your public network.  You will need all the addresses in the range available.  See the previous post for the exact settings I used. I chose 10.97.230.1 as the server.  The rest of the 10.97.230 range is what I will use later.  For the curious, those numbers are based on elements of my home address.  Not truly random, but good enough for this project. Do not bridge the network connections.  I never allowed the cluster nodes direct access to any public network. Format the fixed VHD and leave it alone for now. Promote the VM to a Domain Controller.  If you have never done this, don’t worry.  The only meaningful decision is what to call the new domain.  I prefer a bogus name that does not correspond to a real Top-Level Domain (TLD).  .com, .biz., .net, .org  are all TLDs that we know and love.  I chose .test as the TLD since it is descriptive AND it does not exist in the real world.  The domain is called MicroAD.  This gives me MicroAD.Test as my domain. During the promotion process, you will be prompted to install DNS as part of the Domain creation process.  You want to accept this option.  The installer will automatically assign this DNS server as the authoritative owner of the MicroAD.test DNS domain (not to be confused with the MicroAD.test Active Directory domain.) For the rest of the DCPROMO process, just accept the defaults. Now let’s make our IP address management easy.  Add the DHCP Role to the server.  Add the server (10.97.230.1 in this case) as the default gateway to assign to DHCP clients.  Here is where you have to be VERY careful and bind it ONLY to the Internal NIC.  Trust me, your network admin will NOT like an extra DHCP server “helping” out on her network.  Go ahead and create a range of 10-20 IP Addresses in your scope.  You might find other uses for a pocket domain controller <cough> Mirroring </cough> than just for building a cluster.  And Clustering in SQL 2008 and Windows 2008 R2 fully supports DHCP addresses. Now we have three of the five key roles ready.  Two more to go. Next comes file sharing.  Since your cluster node VMs will not have access to any outside, you have to have some way to get files into these VMs.  I simply go to the root of C: and create a “Shared” folder.  I then share it out and grant full control to “Everyone” to both the share and to the underlying NTFS folder.   This will be immensely useful for Service Packs, demo databases, and any other software that isn’t packaged as an ISO that we can mount to the VM. Finally we need to create a block-level multi-connect storage device.  The kind folks at Starwinds Software (http://www.starwindsoftware.com/) graciously gave me a non-expiring demo license for expressly this purpose.  Their iSCSI SAN software lets you create an iSCSI target from nearly any storage medium.  Refreshingly, their product does exactly what they say it does.  Thanks. Remember that 16 GB VHD file?  That is where we are going to carve into our LUNs.  I created an iSCSI folder off the root, just so I can keep everything organized.  I then carved 5 ea. 2 GB iSCSI targets from that folder.  I chose a fixed VHD for performance.  I tried this earlier with a dynamically expanding VHD, but too many layers of abstraction and sparseness combined to make it unusable even for a demo.  Stick with a fixed VHD so there is a one-to-one mapping between abstract and physical storage.  If you read the previous post, you know what I named these iSCSI LUNs and why.  Yes, I do have some left over space.  Always leave yourself room for future growth or options. This gets us up to where we can actually build the nodes and install SQL.  As with most clusters, the real work happens long before the individual nodes get installed and configured.  At least it does if you want the cluster to be a true high-availability platform.

  • The Data Scientist

    - by BuckWoody
    A new term - well, perhaps not that new - has come up and I’m actually very excited about it. The term is Data Scientist, and since it’s new, it’s fairly undefined. I’ll explain what I think it means, and why I’m excited about it. In general, I’ve found the term deals at its most basic with analyzing data. Of course, we all do that, and the term itself in that definition is redundant. There is no science that I know of that does not work with analyzing lots of data. But the term seems to refer to more than the common practices of looking at data visually, putting it in a spreadsheet or report, or even using simple coding to examine data sets. The term Data Scientist (as far as I can make out this early in it’s use) is someone who has a strong understanding of data sources, relevance (statistical and otherwise) and processing methods as well as front-end displays of large sets of complicated data. Some - but not all - Business Intelligence professionals have these skills. In other cases, senior developers, database architects or others fill these needs, but in my experience, many lack the strong mathematical skills needed to make these choices properly. I’ve divided the knowledge base for someone that would wear this title into three large segments. It remains to be seen if a given Data Scientist would be responsible for knowing all these areas or would specialize. There are pretty high requirements on the math side, specifically in graduate-degree level statistics, but in my experience a company will only have a few of these folks, so they are expected to know quite a bit in each of these areas. Persistence The first area is finding, cleaning and storing the data. In some cases, no cleaning is done prior to storage - it’s just identified and the cleansing is done in a later step. This area is where the professional would be able to tell if a particular data set should be stored in a Relational Database Management System (RDBMS), across a set of key/value pair storage (NoSQL) or in a file system like HDFS (part of the Hadoop landscape) or other methods. Or do you examine the stream of data without storing it in another system at all? This is an important decision - it’s a foundation choice that deals not only with a lot of expense of purchasing systems or even using Cloud Computing (PaaS, SaaS or IaaS) to source it, but also the skillsets and other resources needed to care and feed the system for a long time. The Data Scientist sets something into motion that will probably outlast his or her career at a company or organization. Often these choices are made by senior developers, database administrators or architects in a company. But sometimes each of these has a certain bias towards making a decision one way or another. The Data Scientist would examine these choices in light of the data itself, starting perhaps even before the business requirements are created. The business may not even be aware of all the strategic and tactical data sources that they have access to. Processing Once the decision is made to store the data, the next set of decisions are based around how to process the data. An RDBMS scales well to a certain level, and provides a high degree of ACID compliance as well as offering a well-known set-based language to work with this data. In other cases, scale should be spread among multiple nodes (as in the case of Hadoop landscapes or NoSQL offerings) or even across a Cloud provider like Windows Azure Table Storage. In fact, in many cases - most of the ones I’m dealing with lately - the data should be split among multiple types of processing environments. This is a newer idea. Many data professionals simply pick a methodology (RDBMS with Star Schemas, NoSQL, etc.) and put all data there, regardless of its shape, processing needs and so on. A Data Scientist is familiar not only with the various processing methods, but how they work, so that they can choose the right one for a given need. This is a huge time commitment, hence the need for a dedicated title like this one. Presentation This is where the need for a Data Scientist is most often already being filled, sometimes with more or less success. The latest Business Intelligence systems are quite good at allowing you to create amazing graphics - but it’s the data behind the graphics that are the most important component of truly effective displays. This is where the mathematics requirement of the Data Scientist title is the most unforgiving. In fact, someone without a good foundation in statistics is not a good candidate for creating reports. Even a basic level of statistics can be dangerous. Anyone who works in analyzing data will tell you that there are multiple errors possible when data just seems right - and basic statistics bears out that you’re on the right track - that are only solvable when you understanding why the statistical formula works the way it does. And there are lots of ways of presenting data. Sometimes all you need is a “yes” or “no” answer that can only come after heavy analysis work. In that case, a simple e-mail might be all the reporting you need. In others, complex relationships and multiple components require a deep understanding of the various graphical methods of presenting data. Knowing which kind of chart, color, graphic or shape conveys a particular datum best is essential knowledge for the Data Scientist. Why I’m excited I love this area of study. I like math, stats, and computing technologies, but it goes beyond that. I love what data can do - how it can help an organization. I’ve been fortunate enough in my professional career these past two decades to work with lots of folks who perform this role at companies from aerospace to medical firms, from manufacturing to retail. Interestingly, the size of the company really isn’t germane here. I worked with one very small bio-tech (cryogenics) company that worked deeply with analysis of complex interrelated data. So  watch this space. No, I’m not leaving Azure or distributed computing or Microsoft. In fact, I think I’m perfectly situated to investigate this role further. We have a huge set of tools, from RDBMS to Hadoop to allow me to explore. And I’m happy to share what I learn along the way.
