  • HTC to launch Windows 7 phone in India

    - by samsudeen
    It is a good news for the Indian smart phone users as the wait is finally over for Windows 7 mobile.The Taiwanese  mobile giant HTC is all set to release its Windows 7 based Smartphone series in India from January. HTC HD7 & HTC Mozart , the two smart phones running on Windows 7 OS started appearing on the HTC Indian website (HTC India) from last week.Though Flip kart (Indian online e-commerce website)  has started getting pre -orders for HTC HD7 a month ago , the buzz has started from last week after the introduction of “HTC Mozart”. The complete feature comparison between both the smart phones is given below.

  • Internet Explorer 9 RC Now Available: Here’s the Most Interesting New Stuff

    - by The Geek
    Yesterday Microsoft announced the release candidate of Internet Explorer 9, which is very close to the final product. Here’s a screenshot tour of the most interesting new stuff, as well as answers to your questions. The most important question is should you install this version? And the answer is absolutely yes. Even if you don’t use IE, it’s better to have a newer, more secure version on your PC. What’s New Under the Hood in Release Candidate vs Beta? If you want to see the full list of changes with all the original marketing detail, you can read Microsoft’s Beauty of the Web page, but here’s the highlights that you might be interested in. Improved Performance – they’ve made a lot of changes, and it really feels faster, especially when using more intensive web apps like Gmail. Power Consumption Settings – since the JavaScript engine in any browser uses a lot of CPU power, they’ve now integrated it into the power settings, so if you’re on battery it will use less CPU, and save battery life. This is really a great change. UI Changes – The tab bar can now be moved below the address bar (see below for more), they’ve shaved some pixels off the design to save space, and now you can toggle the Menu bar to be always on. Pinned Sites – now you can pin multiple pages to a single taskbar button. Very useful if you always use a couple web apps together. You can also pin a site in InPrivate mode. FlashBlock and AdBlock are Integrated (sorta) – there’s a new ActiveX filtering that lets you enable plug-ins only for sites you trust. There’s also a tracking protection list that can block certain content (which can obviously be used to block ads). Geolocation – while a lot of privacy conscious people might complain about this, if you use your laptop while traveling, it’s really useful to have geo-located features when using Google Maps, etc. Don’t worry, it won’t leak your privacy by default. WebM Video – Yeah, Google recently removed H.264 from Chrome, but Microsoft has added Google’s WebM video format to Internet Explorer.

Kernel message: [ 0.208079] [Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored ADVICE: This is not exactly a failure mode but a warning from the kernel. The _OSI() method has implemented a match to the 'Linux' query in the DSDT and this is redundant because the ACPI driver matches onto the Windows _OSI strings by default.

MaxReadReq for pci://00:02:00.0 Network controller: Intel Corporation PRO/Wireless 5100 AGN [Shiloh] Network Connection is low (128) [Network controller]. FAILED [LOW] LowMaxReadReq: Test 1, 2 devices have low MaxReadReq settings. Firmware may have configured these too low. ADVICE: The MaxReadRequest size is set too low and will affect performance. It will provide excellent bus sharing at the cost of bus data transfer rates. Although not a critical issue, it may be worth considering setting the MaxReadRequest size to 256 or 512 to increase throughput on the PCI Express bus. Some drivers (for example the Brocade Fibre Channel driver) allow one to override the firmware settings. Where possible, this BIOS configuration setting is worth increasing it a little more for better performance at a small reduction of bus sharing. ==================================================================================================== PCIe ASPM check. ---------------------------------------------------------------------------------------------------- Test 1 of 2: PCIe ASPM ACPI test. PCIE ASPM is not controlled by Linux kernel. ADVICE: BIOS reports that Linux kernel should not modify ASPM settings that BIOS configured. It can be intentional because hardware vendors identified some capability bugs between the motherboard and the add-on cards. Test 2 of 2: PCIe ASPM registers test.

There is also an extended 64 bit version of this, the X_FIRMWARE_CTRL pointer that also can point to the FACS. Section 5.2.9 of the ACPI specification states that if the X_FIRMWARE_CTRL field contains a non zero value then the FIRMWARE_CTRL field *must* be zero. This error is also detected by the Linux kernel. If FIRMWARE_CTRL and X_FIRMWARE_CTRL are defined, then the kernel just uses the 64 bit version of the pointer. PASSED: Test 1, Table HPET passed.

  • Running Windows Phone Developers Tools CTP under VMWare Player - Yes you can! - But do you want to?

    - by Liam Westley
    This blog is the result of a quick investigation of running the Windows Phone Developer Tools CTP under VMWare Player.  In the release notes for Windows Phone Developer Tools CTP it mentions that it is not supported under VirtualPC or Hyper-V.  Some developers have policies where ‘no non-production code’ can be installed on their development workstation and so the only way they can use a CTP like this is in a virtual machine. The dilemma here is that the emulator for Windows Phone itself is a virtual machine and running a virtual machine within another virtual machine is normally frowned upon.  Even worse, previous Windows Mobile emulators detected they were in a virtual machine and refused to run.  Why VMWare? I selected VMWare as a possible solution as it is possible to run VMWare ESXi under VMWare Workstation by manually setting configuration options in the VMX configuration file so that it does not detect the presence of a virtual environment. I actually found that I could use VMWare Player (the free version, that can now create VM images) and that there was no need for any editing of the configuration file (I tried various switches, none of which made any difference to performance). So you can run the CTP under VMWare Player, that’s the good news. The bad news is that it is incredibly slow, bordering on unusable.  However, if it’s the only way you can use the CTP, at least this is an option. VMWare Player configuration I used the latest VMWare Player, 3.0, running under Windows x64 on my HP 6910p laptop with an Intel T7500 Dual Core CPU running at 2.2GHz, 4Gb of memory and using a separate drive for the virtual machines. I created a machine in VMWare Player with a single CPU, 1536 Mb memory and installed Windows 7 x64 from an ISO image.  I then performed a Windows Update, installed VMWare Tools, and finally the Windows Phone Developer Tools CTP After a few warnings about performance, I configured Windows 7 to run with Windows 7 Basic theme rather than use Aero (which is available under VMWare Player as it has a WDDM driver). Timings As a test I first launched Microsoft Visual Studio 2010 Express for Windows Phone, and created a default Windows Phone Application project.  I then clicked the run button, which starts the emulator and then loads the default application onto the emulator. For the second test I left the emulator running, stopped the default application, added a single button to change the page title and redeployed to the already running emulator by clicking the run button.   Test 1 (1st run) Test 2 (emulator already running)   VMWare Player 10 minutes  1 minute   Windows x64 native 1 minute  < 10 seconds   Conclusion You can run the Windows Phone Developer Tools CTP under VMWare Player, but it’s really, really slow and you would have to have very good reasons to try this approach. If you need to keep a development system free of non production code, and the two systems aren’t required to run simultaneously, then I’d consider a boot from VHD option.  Then you can completely isolate the Windows Phone Developer Tools CTP and development environment into a single VHD separate from your main development system.

  • April 2010 Critical Patch Update Released

    - by eric.maurice
    Hi, this is Eric Maurice. Today Oracle released the April 2010 Critical Patch Update (CPUApr2010),the first one to include security fixes for Oracle Solaris. Today's Critical Patch Update (CPU) provides 47 new security fixes across the following product families: Oracle Database Server, Oracle Fusion Middleware, Oracle Collaboration Suite, Oracle E-Business Suite, Oracle PeopleSoft Enterprise, Oracle Life Sciences, Retail, and Communications Industry Suites, and Oracle Solaris. 28 of these 47 new vulnerabilities are remotely exploitable without authentication, but the criticality of the affected components and the severity of these vulnerabilities vary greatly. Customers should, as usual, refer to the Risk Matrices in the CPU Advisory to assess the relevance of these fixes for their environment (and the urgency with which to apply the fixes). 7 of the 47 new vulnerabilities affect various versions of Oracle Database Server. None of these 7 vulnerabilities are remotely exploitable without authentication. Furthermore, none of these fixes are applicable to client-only deployments. The most severe CVSS Base Score for the Database Server vulnerabilities is 7.1. As a reminder, information about Oracle's use of the CVSS 2.0 standard can be found in Note 394487.1 (My Oracle Support subscription required). Note that this Critical Patch Update includes fixes for vulnerabilities that were publicly disclosed by David Litchfield at the BlackHat DC Conference in early February (CVE-2010-0866 and CVE-2010-0867). 5 of the 47 new vulnerabilities affect various components of the Oracle Fusion Middleware product family. The highest CVSS Base Score for these vulnerabilities is 7.5. Note that the patches for Oracle WebLogic Server are cumulative and this Critical Patch Update therefore also includes a fix for a vulnerability (CVE-2010-0073) that was the subject of a Security Alert issued by Oracle on February 4, 2010. Customers, who have not applied the previously-released patch, should apply today's Critical Patch Update as soon as possible. As stated at the beginning of this blog, it is also noteworthy to highlight that this Critical Patch Update provides 16 new fixes for the Sun product line. With the recent close of the Sun acquisition both security organizations have worked diligently to align Sun's previous security practices with Oracle's. Java users know that Oracle released a Critical Patch Update for Java SE and Java For Business earlier this month (in accordance with the Java patching schedule previously published by Sun Microsystems). Please note that for the first time, the Java advisories included CVSS Scores to help assess the severity of the new vulnerabilities fixed with the advisory. The rapid inclusion of the Solaris product lines in the Critical Patch Update and the extension of Oracle Software Security Assurance to Sun technologies are evidence of the flexibility of Oracle's security assurance programs. These should also result in tangible security benefits for the users of the Oracle hardware and software stack (such as a predictable patching schedule for all Oracle products).

  • TSAM 11gR1

    - by todd.little
    The Tuxedo System and Application Monitor (TSAM) 11gR1 release provides powerful new application monitoring capabilities, as well as significant improvements in ease of use. The first thing users will notice is the completely redesigned user interface in the TSAM console. Based on Oracle ADF, the console is much easier to navigate, provides a Web 2.0 style interface with dynamically updating panels, and a look and feel familiar to those that have used Oracle Enterprise Manager. Monitoring data can be viewed in both tabular and graphical form and exported to Excel for further analysis. A number of new metrics are collected and displayed in this release. Call path monitoring now displays CPU time, message size, total transport time, and client address giving even more end-to-end information about a specific Tuxedo request. As well the call path display has been completely revamped to make it much easier to see the branches of the call path. The call pattern display now provides statistics on successful vs failed calls, system and application failures, and end-to-end average elapsed time. Service monitoring now displays minimum and maximum message size, CPU usage, and client address. System server monitoring now includes monitoring the SALT gateway servers to provide detailed performance metrics about those servers. Perhaps the most significant new feature is the consolidation of alert definitions and policy management. In previous versions of TSAM, some alerts were defined and checked on the monitored systems while others were defined and checked in the console. Policy management could be performed on both the monitored node via environment variable or command, as well as from the console. Now all alert definitions and policy definitions are only made using the console. For alerts this means that regardless of where the alert is evaluated it is defined in one and only one place. Thus the plug-in alert mechanism of previous releases can now be managed using the TSAM console, making SLA alert definition much easier and cleaner. Finally there is support in TSAM for monitoring rehosted mainframe applications. The newly announced Oracle Tuxedo Application Runtime for CICS and Batch can be monitored in the TSAM console using traditional mainframe views of the application such as regions. Look for a future blog entry with more details on this as well as some entries providing a glimpse of the console. TSAM gives users a single point for monitoring the performance of all of their Tuxedo applications.

  • 10.10 freezing when sftp downloading

    - by aGr
    My ubuntu 10.10 is freezing during downloading from my other computer on sftp. I thought it might be some nautilus issues so I tried it via command line and I got the same thing - after few minutes the whole computer freezes. Mostly the numlock led is blinking (I've heard somewhere that this means a kernel panic), but not in 100% cases. I dunno if that helps but here is a log from /var/log/message in the time that this happened. At least I hope so - it wasn't that big, when it happened before. But this looks quite "errorish", right?

  • What's up with LDoms: Part 2 - Creating a first, simple guest

    - by Stefan Hinker
    Welcome back! In the first part, we discussed the basic concepts of LDoms and how to configure a simple control domain.  We saw how resources were put aside for guest systems and what infrastructure we need for them.  With that, we are now ready to create a first, very simple guest domain.  In this first example, we'll keep things very simple.  Later on, we'll have a detailed look at things like sizing, IO redundancy, other types of IO as well as security. For now,let's start with this very simple guest.  It'll have one core's worth of CPU, one crypto unit, 8GB of RAM, a single boot disk and one network port.  CPU and RAM are easy.  The network port we'll create by attaching a virtual network port to the vswitch we created in the primary domain.  This is very much like plugging a cable into a computer system on one end and a network switch on the other.  For the boot disk, we'll need two things: A physical piece of storage to hold the data - this is called the backend device in LDoms speak.  And then a mapping between that storage and the guest domain, giving it access to that virtual disk.  For this example, we'll use a ZFS volume for the backend.  We'll discuss what other options there are for this and how to chose the right one in a later article.  Here we go: root@sun # ldm create mars root@sun # ldm set-vcpu 8 mars root@sun # ldm set-mau 1 mars root@sun # ldm set-memory 8g mars root@sun # zfs create rpool/guests root@sun # zfs create -V 32g rpool/guests/mars.bootdisk root@sun # ldm add-vdsdev /dev/zvol/dsk/rpool/guests/mars.bootdisk \ mars.root@primary-vds root@sun # ldm add-vdisk root mars.root@primary-vds mars root@sun # ldm add-vnet net0 switch-primary mars That's all, mars is now ready to power on.  There are just three commands between us and the OK prompt of mars:  We have to "bind" the domain, start it and connect to its console.  Binding is the process where the hypervisor actually puts all the pieces that we've configured together.  If we made a mistake, binding is where we'll be told (starting in version 2.1, a lot of sanity checking has been put into the config commands themselves, but binding will catch everything else).  Once bound, we can start (and of course later stop) the domain, which will trigger the boot process of OBP.  By default, the domain will then try to boot right away.  If we don't want that, we can set "auto-boot?" to false.  Finally, we'll use telnet to connect to the console of our newly created guest.  The output of "ldm list" shows us what port has been assigned to mars.  By default, the console service only listens on the loopback interface, so using telnet is not a large security concern here. root@sun # ldm set-variable auto-boot\?=false mars root@sun # ldm bind mars root@sun # ldm start mars root@sun # ldm list NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME primary active -n-cv- UART 8 7680M 0.5% 1d 4h 30m mars active -t---- 5000 8 8G 12% 1s root@sun # telnet localhost 5000 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. ~Connecting to console "mars" in group "mars" .... Press ~? for control options .. {0} ok banner SPARC T3-4, No Keyboard Copyright (c) 1998, 2011, Oracle and/or its affiliates. All rights reserved. OpenBoot 4.33.1, 8192 MB memory available, Serial # 87203131. Ethernet address 0:21:28:24:1b:50, Host ID: 85241b50. {0} ok We're done, mars is ready to install Solaris, preferably using AI, of course ;-)  But before we do that, let's have a little look at the OBP environment to see how our virtual devices show up here: {0} ok printenv auto-boot? auto-boot? = false {0} ok printenv boot-device boot-device = disk net {0} ok devalias root /virtual-devices@100/channel-devices@200/disk@0 net0 /virtual-devices@100/channel-devices@200/network@0 net /virtual-devices@100/channel-devices@200/network@0 disk /virtual-devices@100/channel-devices@200/disk@0 virtual-console /virtual-devices/console@1 name aliases We can see that setting the OBP variable "auto-boot?" to false with the ldm command worked.  Of course, we'd normally set this to "true" to allow Solaris to boot right away once the LDom guest is started.  The setting for "boot-device" is the default "disk net", which means OBP would try to boot off the devices pointed to by the aliases "disk" and "net" in that order, which usually means "disk" once Solaris is installed on the disk image.  The actual devices these aliases point to are shown with the command "devalias".  Here, we have one line for both "disk" and "net".  The device paths speak for themselves.  Note that each of these devices has a second alias: "net0" for the network device and "root" for the disk device.  These are the very same names we've given these devices in the control domain with the commands "ldm add-vnet" and "ldm add-vdisk".  Remember this, as it is very useful once you have several dozen disk devices... To wrap this up, in this part we've created a simple guest domain, complete with CPU, memory, boot disk and network connectivity.  This should be enough to get you going.  I will cover all the more advanced features and a little more theoretical background in several follow-on articles.  For some background reading, I'd recommend the following links: LDoms 2.2 Admin Guide: Setting up Guest Domains Virtual Console Server: vntsd manpage - This includes the control sequences and commands available to control the console session.

    In case you haven’t heard Windows 8 is now available. As a web developer I think one of the best reasons to upgrade to Windows 8 is that you can start testing IIS 8 right from your PC. This way if you don’t have a budget for a new server you can start to familiarize yourself with some of the new features. IIS 8 has some great new features such as Dynamic IP Restrictions an Application Initialization . However one of the best new features of IIS 8 enables you to throttle the CPU utilization for any...(read more)

  • The winning combination: Oracle VM Server for x86 + Oracle Sun Fire HW

    - by Karim Berrah
    You might be wondering why OVM Server for x86 (OVM/x86 here and below) should be seriously considered as a nice (business point of view) alternative to standard Hypervisors, if you are virtualizing Oracle Software, especially if you are planning to move to Oracle x86 Hardware (rackmount or blades). Well, let see some "not well known" facts that might interest you and help you in saving more money for your entire company (and not only the Virtulization team). Fact 1: OVM/x86 is considered as a hard partitionning technology (check page 2 of Oracle Server Partitionning Licencing Policies), so if you are buying new servers based on the latest INTEL Xeon E7 CPUs (10 cores per Socket) and have some licencing issues in deploying further Oracle SW, because you are using a hypervisor not recognized as a hard partitionning technology (like VMware), then you need to check here how to do it with OVM . This might help you to continue to deploy your Oracle DB instances on new x86 HW (12 cores, 40 cores, 64 cores servers) in a reasonable way, without having to pay licences for 12 CPU, 40 CPUs or 64 CPUs. You might also consider migrating your legacy Oracle DB DBs to a virtualized environment like OVM/x86 an recover some CPU licences, that can be reused somewhere else in production. Fact 2: OVM/x86 is free to use, without any extra licence for any specific feature (LiveMigration, High Availability, Embedded Management Console). If you want to use it on non Oracle HW, there is a support fee per  system and per year, that is much below VMware support (Oracle VM Premier Limited Support for systems up to 2 CPUs, and Oracle VM Premier Support for any bigger system, independently on the number of populated sockets). Fact 3: support is included with your Oracle x86 HW support (OPS for systems)  and you can re-install on you system Oracle Linux, Oracle Solaris or Oracle VM server for x86, without beeing charged, an keeping the same support level. Fact 4: it is less expensive to virtualize Oracle Linux or Oracle Solaris on OVM/x86 with Oracle HW that any other similar solution with VMware, because all the VMs are then supported and licenced when you buy Oracle HW with OPS. Fact 5: Oracle VM Templates bring you many Virtual Machines already installed, patched and optimized for various Oracle applications. And to be more specific, those templates are fully supported by Oracle, which is not really true when it comes to another hypervisor. By optimized VM Kernel, I mean PV drivers, OVM-ready kernels in the VM, single source clock for all the VMS, better memory management of the VM ... Fact 6: there is no extra costs for a management console. OVM comes with a free OVM Manager package for Linux.  More infos: Latest announcement of OVM/x86 update 2.2.2 A short flash demo of OVM server for x86 A short flash demo on OVM Templates and Virtual Assembly Builder Oracle Linux Support and Oracle VM Support Global Price List  ISVs: Benefits for Independant Sofwtare Vendors (ISVs) in using OVM/x86 Consultant Services: Advanced Customer Services for OVM/x86  Technical Features Best practices and Guideline for OVM with Oracle Blades Reduce TCO and get more Value from your x86 Infrastructure

  • Using Node.js as an accelerator for WCF REST services

    - by Elton Stoneman
    Node.js is a server-side JavaScript platform "for easily building fast, scalable network applications". It's built on Google's V8 JavaScript engine and uses an (almost) entirely async event-driven processing model, running in a single thread. If you're new to Node and your reaction is "why would I want to run JavaScript on the server side?", this is the headline answer: in 150 lines of JavaScript you can build a Node.js app which works as an accelerator for WCF REST services*. It can double your messages-per-second throughput, halve your CPU workload and use one-fifth of the memory footprint, compared to the WCF services direct.   Well, it can if: 1) your WCF services are first-class HTTP citizens, honouring client cache ETag headers in request and response; 2) your services do a reasonable amount of work to build a response; 3) your data is read more often than it's written. In one of my projects I have a set of REST services in WCF which deal with data that only gets updated weekly, but which can be read hundreds of times an hour. The services issue ETags and will return a 304 if the client sends a request with the current ETag, which means in the most common scenario the client uses its local cached copy. But when the weekly update happens, then all the client caches are invalidated and they all need the same new data. Then the service will get hundreds of requests with old ETags, and they go through the full service stack to build the same response for each, taking up threads and processing time. Part of that processing means going off to a database on a separate cloud, which introduces more latency and downtime potential.   We can use ASP.NET output caching with WCF to solve the repeated processing problem, but the server will still be thread-bound on incoming requests, and to get the current ETags reliably needs a database call per request. The accelerator solves that by running as a proxy - all client calls come into the proxy, and the proxy routes calls to the underlying REST service. We could use Node as a straight passthrough proxy and expect some benefit, as the server would be less thread-bound, but we would still have one WCF and one database call per proxy call. But add some smart caching logic to the proxy, and share ETags between Node and WCF (so the proxy doesn't even need to call the servcie to get the current ETag), and the underlying service will only be invoked when data has changed, and then only once - all subsequent client requests will be served from the proxy cache.   I've built this as a sample up on GitHub: NodeWcfAccelerator on sixeyed.codegallery. Here's how the architecture looks:     The code is very simple. The Node proxy runs on port 8010 and all client requests target the proxy. If the client request has an ETag header then the proxy looks up the ETag in the tag cache to see if it is current - the sample uses memcached to share ETags between .NET and Node. If the ETag from the client matches the current server tag, the proxy sends a 304 response with an empty body to the client, telling it to use its own cached version of the data. If the ETag from the client is stale, the proxy looks for a local cached version of the response, checking for a file named after the current ETag. If that file exists, its contents are returned to the client as the body in a 200 response, which includes the current ETag in the header. If the proxy does not have a local cached file for the service response, it calls the service, and writes the WCF response to the local cache file, and to the body of a 200 response for the client. So the WCF service is only troubled if both client and proxy have stale (or no) caches.   The only (vaguely) clever bit in the sample is using the ETag cache, so the proxy can serve cached requests without any communication with the underlying service, which it does completely generically, so the proxy has no notion of what it is serving or what the services it proxies are doing. The relative path from the URL is used as the lookup key, so there's no shared key-generation logic between .NET and Node, and when WCF stores a tag it also stores the "read" URL against the ETag so it can be used for a reverse lookup, e.g:   Key Value /WcfSampleService/PersonService.svc/rest/fetch/3 "28cd4796-76b8-451b-adfd-75cb50a50fa6" "28cd4796-76b8-451b-adfd-75cb50a50fa6" /WcfSampleService/PersonService.svc/rest/fetch/3    In Node we read the cache using the incoming URL path as the key and we know that "28cd4796-76b8-451b-adfd-75cb50a50fa6" is the current ETag; we look for a local cached response in /caches/28cd4796-76b8-451b-adfd-75cb50a50fa6.body (and the corresponding .header file which contains the original service response headers, so the proxy response is exactly the same as the underlying service). When the data is updated, we need to invalidate the ETag cache – which is why we need the reverse lookup in the cache. In the WCF update service, we don't need to know the URL of the related read service - we fetch the entity from the database, do a reverse lookup on the tag cache using the old ETag to get the read URL, update the new ETag against the URL, store the new reverse lookup and delete the old one.   Running Apache Bench against the two endpoints gives the headline performance comparison. Making 1000 requests with concurrency of 100, and not sending any ETag headers in the requests, with the Node proxy I get 102 requests handled per second, average response time of 975 milliseconds with 90% of responses served within 850 milliseconds; going direct to WCF with the same parameters, I get 53 requests handled per second, mean response time of 1853 milliseconds, with 90% of response served within 3260 milliseconds. Informally monitoring server usage during the tests, Node maxed at 20% CPU and 20Mb memory; IIS maxed at 60% CPU and 100Mb memory.   Note that the sample WCF service does a database read and sleeps for 250 milliseconds to simulate a moderate processing load, so this is *not* a baseline Node-vs-WCF comparison, but for similar scenarios where the  service call is expensive but applicable to numerous clients for a long timespan, the performance boost from the accelerator is considerable.     * - actually, the accelerator will work nicely for any HTTP request, where the URL (path + querystring) uniquely identifies a resource. In the sample, there is an assumption that the ETag is a GUID wrapped in double-quotes (e.g. "28cd4796-76b8-451b-adfd-75cb50a50fa6") – which is the default for WCF services. I use that assumption to name the cache files uniquely, but it is a trivial change to adapt to other ETag formats.

  • Google Earth freezes during zoom-in on Intel processors with integrated graphics

    - by zigma80
    When I zoom in at a certain zoom level, Google Earth makes my system freeze completely so that I have to power off or reboot I use Kubuntu 12.04 and my laptop has an Intel(R)Core(TM)i3-2310M CPU @2.10GHz with HD3000 graphics. I installed intel-gpu-tools and tried to fix it with sudo intel_reg_write 0x2120 0x1206800 as explained [here][1], but that didn't work. I wonder if there any other solution out there...

  • Core Parking in Ubuntu?

    - by Xxx Xxx
    Core parking is a new feature that introduced in Windows 7 to get better Battery performance . Depending on the resource use of the operating system it may park one or multiple cores of a multi-core cpu to reduce the computer’s power consumption and thermal emissions. Once operations require more processing power, the parked cores are activated again to assist in the tasks So my question is that is there any way i can do it on Ubuntu 12.04 " Core Parking " ?

    I want to write an application where I can fetch system information like CPU-Z (for example) does. I don't want to rely on WMI, because I want to grab stuff like information about the manufacturing process of the GPU (like from a database) and I don't want to maintain this by myself, because that would require too much effort. I already came up with HWiNFO32 SDK but I wonder if there are any (maybe free) alternatives to it?
