  • Is there an Android remote app compatible with LibreOffice Impress under Ubuntu?

    - by WarriorIng64
    I have an upcoming presentation I want to make in LibreOffice Impress on my Ubuntu 12.10 laptop. I was wondering if I could get ahold of an Android app which would act like a remote control, allowing me to switch between slides from my phone over WiFi without having to stay near the laptop (I've been told I need to move around more during my presentations). A quick look on the Google Play store seemed to turn up a handful of PowerPoint remote apps for Windows or maybe Mac. I also took a look at Can an Android phone control Ubuntu like a remote?, but that seems more for controlling an Ubuntu media center. Is there anything which will work with LibreOffice Impress on Ubuntu? My phone is a Samsung Galaxy Precedent on Straight Talk, running Android 2.2.2 (latest available version from the carrier). It's not rooted, and there's not much memory on it either, so the smaller and simpler the app the better. Also, it has to be free because I currently don't have a means to pay for an app I may/may not like.

  • How to get my external IP address (over NAT) from the Windows command-line?

    - by Diogo Rocha
    The Windows "ipconfig" command can only show me the parameters from the Ethernet interfaces from my machine (even with the "ipconfig /all" argument). It can show detailed information about the interface, but it will never show me my external IP address over a NAT network. However, there are several websites, such as "What is my IP address" that can get and show my external IP address. So I'm wondering, is possible to get this value externally? Should I expect that there is some way to get this information from a command line at my local machine... I need to get this value to log on an application that I'm doing with VBScript. There is some way to do this, from a "cmd" on Windows?

  • Developing geometry-based Web Services for WebLogic | Part 1 by Ronald van Luttikhuizen

    - by JuergenKress
    In a recent project we developed Web Services that expose geographical data in their operations. This blog explains the use case for the service, gives an overview of the software architecture, and briefly discusses GML as markup language for geographical data. Part 2 of this blog provides pointers on the implementation of the service while part 3 discusses the deployment on Oracle WebLogic Server. Use Case The "BAG" (Basisregistratie Adressen en Gebouwen) is a Dutch national database containing information on all addresses and buildings in the Netherlands, and is maintained by Dutch municipalities. For several object types the BAG also maintains the associated geographical location and shape; for example for premises and cities. Read the complete article here.

  • Workshop in Holland - and open questions

    - by Mike Dietrich
    Thanks to everybody visiting yesterday the Upgrade Workshop in Maarsen. I had lots of fun - and I hope you'd enjoy it, too :-) The slides, as always, can be downloaded from: http://apex.oracle.com/folien Use the Schluesselwort/Keyword: upgrade112 And thanks to all those of you sending feedback regarding "traget/destination" (will change it in the slides) and other topics such as Enterprise Manager Grid Control 11g. Enterprise Manager 11g will be launched on 22-APR-2010 - and you can join the event live if you will be accidentialy in New York:http://www.oracle.com/enterprisemanager11g/index.html Thanks for this hint!!! Regarding the open questions: Will there be PSUs available for Intel Solaris? PSUs will be made available on nearly all platforms including Intel Solaris. Please see Note:882604.1 for platform information and Note:854428.1 for direct links to the PSU download location. Is COMMIT_WRITE=NOWAIT the default in patch set 10.2.0.4? I tried to verify this and neither couldn't find a bug entry nor a documentation saying the 10.2.0.4 has a different default setting (default behaviour is WAIT). Checked it in my 10.2.0.4 instances as well and there it is set to WAIT. If this parameter is not explicitly specified, then database commit behavior defaults to writing commit records to disk before control is returned to the client. If only IMMEDIATE or BATCH is specified, but not WAIT or NOWAIT, then WAIT mode is assumed. If only WAIT or NOWAIT is specified, but not IMMEDIATE or BATCH, then IMMEDIATE mode is assumed Please feedback to me if you have different experiences. Service Request escalation by telephone? Thanks for this update - I didn't realize that ;-) Now I know why it hasn't helped last month when I've updated an SR ... here's the official information on that: Note:199389.1 - Note has been updated on 24-FEB-2010. See the telephone number to Oracle support to request an escalation here: http://www.oracle.com/support/contact.html

  • Question to ask during interviews to get a sense of the development process

    - by davidk01
    I just watched a presentation about simplicity by Rich Hickey at InfoQ where he goes over the constructs programmers use to produce artifacts and how those constructs make various trade-offs when it comes to achieving simple artifacts. I think that most programmers would agree with a lot of what he says but at the end of the day I don't know how many development shops are actively practicing development processes and using tools that allow them to make simple artifacts. As an interview candidate I would like to work at a software development shop where producing simple artifacts is a top priority. What are some questions I can ask to figure out if the place that is interviewing me is actually such a place.

  • OSX 10.6.6 SSH md5 break-in check

    - by Alex
    Information Recently one of the linux servers that I access was compromised to steal passwords and ssh keys using a modified ssh binary. This lead me to question if the attacker had compromised my OSX Laptop which had ssh access turned on. A sophos virus scan turned up nothing, and I did not have rkhunter installed before the attack, so I could not compare hashes of the system binaries to be sure. However because OSX is relatively standard for each of their major releases, I asked fiends for md5 hashes md5 /usr/bin/ssh and md5 /usr/sbin/sshd as a basic first check to see if there was anything different about my machine. A few emails later I have found the following data: Version (Arch) [N] MD5 (/usr/bin/ssh) MD5 (/usr/sbin/sshd) OSX 10.5.8 (PPC) [3] 1e9fd483eef23464ec61c815f7984d61 9d32a36294565368728c18de466e69f1 OSX 10.5.8 (intel) [5] 1e9fd483eef23464ec61c815f7984d61 9d32a36294565368728c18de466e69f1 OSX 10.6.x (intel) [7] 591fbe723011c17b6ce41c537353b059 e781fad4fc86cf652f6df22106e0bf0e OSX 10.6.x (intel) [4] 58be068ad5e575c303ec348a1c71d48b 33dafd419194b04a558c8404b484f650 Mine 10.6.6 (intel) df344cc00a294c91230c65e8b7332a79 b5094ccf4cd074aaf573d4f5df75906a where N is the number of machines with with that MD5, and the last row is my laptop. The sample is relatively heterogeneous spaning a few years of different makes and models of Apples, and different versions of 10.6.x. The different hash for my system made me worried that these binaries might have been compromised. So I made sure that my backup for the week was good, and dived into formatting my system and reinstalling OSX. After reinstalling OSX from the manufacturer DVD, I found that the MD5 hash did not change for either ssh, or sshd. Goal Make sure that my system is does not have any malicious software. Should I be worried that this base install of OSX (with no other software installed) has been compromised? I have also updated my system to 10.6.6 and found no change as well. Other Information I am not sure if this is helpful information, but my laptop is a i7 15 inch MacBook Pro bought in Nov 2010, and here is some output from system_profiler: System Software Overview: System Version: Mac OS X 10.6.6 (10J567) Kernel Version: Darwin 10.6.0 64-bit Kernel and Extensions: No Time since boot: 1:37 Hardware: Hardware Overview: Model Name: MacBook Model Identifier: MacBook6,2 Processor Name: Intel Core i7 Processor Speed: 2.66 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache (per core): 256 KB L3 Cache: 4 MB Memory: 4 GB Processor Interconnect Speed: 4.8 GT/s Boot ROM Version: MBP61.0057.B0C SMC Version (system): 1.58f16 Sudden Motion Sensor: State: Enabled On the laptop, I find: $ codesign -vvv /usr/bin/ssh /usr/bin/ssh: valid on disk /usr/bin/ssh: satisfies its Designated Requirement $ codesign -vvv /usr/sbin/sshd /usr/sbin/sshd: valid on disk /usr/sbin/sshd: satisfies its Designated Requirement $ ls -la /usr/bin/ssh -rwxr-xr-x 1 root wheel 1001520 Feb 11 2010 /usr/bin/ssh $ ls -la /usr/sbin/sshd -rwxr-xr-x 1 root wheel 1304800 Feb 11 2010 /usr/sbin/sshd $ ls -la /sbin/md5 -r-xr-xr-x 1 root wheel 65232 May 18 2009 /sbin/md5 Update So far I have not gotten an answer about this question, but if you could help by increasing the number of hashes that I can compare against, that would be great. To get hashes, and version numbers, run the following on osx: md5 /usr/bin/ssh md5 /usr/sbin/sshd ssh -V sw_vers

  • 3G/Edge/GPRS IP addresses and geocoding

    - by LookitsPuck
    Hey all! So, we're looking to develop a mobile website. On this mobile website, we'd like to automatically populate a user's location (with proper fallback) based on their IP address. I'm aware of geocoding a location based on IP address (mapping to latitude, longitude and then getting the location with that information). However, I'm curious how accurate this information is? Are mobile devices assigned IP's when they utilize 3G, EDGE, and GPRS connections? I think so. If that is so, does it map to a relatively accurate location? It doesn't have to be spot on, but relatively accurate would be nice. Thanks! -Steve

  • Solving Kaggle’s Bike Sharing Demand Machine Learning Problem

    - by Gopinath
    Kaggle.com hosts a lot of interesting machine learning problems online and thousands of its members compete to solve them for a bounty. Problems hosted on Kaggle has varying complexity to accomodate newbies to rock star developers – few problems are good enough for  newbies to learn basics of machine learning and few of them challenge the best of machine learning developers. I’m learning basics of machine learning for the past few weeks and had an opportunity to solve Kaggel’s Bike Sharing Demand problem. Bike Sharing systems allows customers to rent a bike (or a cycle as it is called in many part of the world) for several hours and return them back . The problem provides historical information about the demand for bike sharing business and we need to forecast the demand. For more information on the problem, visit Kaggle.com website. Here is the solution I written using random forests algorithm using R programming language and you can download the source code from github.  With this solution I was able to score RMSLE of 0.70117, which placed me somewhere in the mid of the leader board.  This is the best score I could get by spending 4 hours of my time. Please feel free to fork the code and improve it.   Get Kaggle Bike Sharing Demand solution code from GitHub

  • Documentation in Oracle Retail Analytics, Release 13.3

    - by Oracle Retail Documentation Team
    The 13.3 Release of Oracle Retail Analytics is now available on the Oracle Software Delivery Cloud and from My Oracle Support. The Oracle Retail Analytics 13.3 release introduced significant new functionality with its new Customer Analytics module. The Customer Analytics module enables you to perform retail analysis of customers and customer segments. Market basket analysis (part of the Customer Analytics module) provides insight into which products have strong affinity with one another. Customer behavior information is obtained from mining sales transaction history, and it is correlated with customer segment attributes to inform promotion strategies. The ability to understand market basket affinities allows marketers to calculate, monitor, and build promotion strategies based on critical metrics such as customer profitability. Highlighted End User Documentation Updates With the addition of Oracle Retail Customer Analytics, the documentation set addresses both modules under the single umbrella name of Oracle Retail Analytics. Note, however, that the modules, Oracle Retail Merchandising Analytics and Oracle Retail Customer Analytics, are licensed separately. To accommodate new functionality, the Retail Analytics suite of documentation has been updated in the following areas, among others: The User Guide has been updated with an overview of Customer Analytics. It also contains a list of metrics associated with Customer Analytics. The Operations Guide provides details on Market Basket Analysis as well as an updated list of APIs. The program reference list now also details the module (Merchandising Analytics or Customer Analytics) to which each program applies. The Data Model was updated to include new information related to Customer Analytics, and a new section, Market Basket Analysis Module, was added to the document with its own entity relationship diagrams and data definitions. List of Documents The following documents are included in Oracle Retail Analytics 13.3: Oracle Retail Analytics Release Notes Oracle Retail Analytics Installation Guide Oracle Retail Analytics User Guide Oracle Retail Analytics Implementation Guide Oracle Retail Analytics Operations Guide Oracle Retail Analytics Data Model

  • Using the JRockit Flight Recorder as an In-Flight Black Box

    - by Marcus Hirt
    The new JRockit Flight Recorder has some very interesting properties. It can be used like the black box of an airplane, allowing users to go back in time and check what was happening around the time when something went wrong. Here is how to enable the default continuous recording in JRockit to allow for that use case. The flight recorder is on by default in JRockit R28, the problem is that there is no recording running by default. To configure JRockit to start with the default recording running, add the parameter: -XX:FlightRecorderOptions=defaultrecording=true That will enable a recording with recording ID 0. You can see that it has been started properly by choosing Show Recordings from the context menu in JRockit Mission Control.   You should see something similar to the picture below. Simply right click on the recording and select dump to dump information available in the flight recorder. You can select to dump data for a specific period of time or all data. For more information about the command line parameters available to control the Flight Recorder, see the JRockit documentation.

  • When Do OS Questions Belong on Hardware Service Requests?

    - by Get Proactive Customer Adoption Team
    Untitled Document My Oracle Support—Logging an Operating System Service Request One of the concerns we hear from our customers with Premier Support for Systems is that they have difficulty logging a Service Request (SR) for an operating system issue. Because Premier Support for Systems includes support for the hardware and the associated operating system, you log any operating system issues through a hardware Service Request. To create a hardware Service Request, you enter the information into the Hardware tab of the Create Service Request screen, but to ensure that the hardware Service Request you enter is recognized and routed appropriately for an operating system issue, you need to change the product from your specific hardware to the operating system that the hardware is running. The example below shows you how to create a Service Request for the operating system when the support level is Premier Support for Systems. The key to success is remembering that the operating system coverage is part of the hardware support. To begin, from anywhere within My Oracle Support, click on the Create SR button as you would to log any SR: Enter your Problem Summary and the Problem Description Next, click on the Hardware tab. Enter the System Serial Number (in this case “12345”) and click on Validate Serial Number: Notice that the product name for the hardware indicates “Sunfire T2000 Server” with an option for a drop down List of Values. Click on the product drop down and choose the correct operating system from the list. In this case I have chosen “OpenSolaris Operating System” Next, you will need to enter the correct operating system version: At this point, you may proceed to complete and submit the Service Request. If your company has Premier Support for Systems, just remember that your operating system has coverage under the hardware it runs on, so start with a Hardware tab on the Service Request screen and change the product related information to reflect the operating system you need help with. Following these simple steps will ensure that the system assigns your Service Request to the right support team for an operating system issue and the support engineer can quickly begin working your issue.

  • Book Review - Programming Windows Azure by Siriram Krishnan

    - by BuckWoody
    As part of my professional development, I’ve created a list of books to read throughout the year, starting in June of 2011. This a review of the first one, called Programming Windows Azure by Siriram Krishnan. You can find my entire list of books I’m reading for my career here: http://blogs.msdn.com/b/buckwoody/archive/2011/06/07/head-in-the-clouds-eyes-on-the-books.aspx  Why I Chose This Book: As part of my learning style, I try to read multiple books about a single subject. I’ve found that at least 3 books are necessary to get the right amount of information to me. This is a “technical” work, meaning that it deals with technology and not business, writing or other facets of my career. I’ll have a mix of all of those as I read along. I chose this work in addition to others I’ve read since it covers everything from an introduction to more advanced topics in a single book. It also has some practical examples of actually working with the product, particularly on storage. Although it’s dated, many examples normally translate. I also saw that it had pretty good reviews. What I learned: I learned a great deal about storage, and many useful code snippets. I do think that there could have been more of a focus on the application fabric - but of course that wasn’t as mature a feature when this book was written. I learned some great architecture examples, and in one section I learned more about encryption. In that example, however, I would rather have seen the examples go the other way - the book focused on moving data from on-premise to Azure storage in an encrypted fashion. Using the Application Fabric I would rather see sensitive data left in a hybrid fashion on premise, and connect to for the Azure application. Even so, the examples were very useful. If you’re looking for a good “starter” Azure book, this is a good choice. I also recommend the last chapter as a quick read for a DBA, or Database Administrator. It’s not very long, but useful. Note that the limits described are incorrect - which is one of the dangers of reading a book about any cloud offering. The services offered are updated so quickly that the information is in constant danger of being “stale”. Even so, I found this a useful book, which I believe will help me work with Azure better. Raw Notes: I take notes as I read, calling that process “reading with a pencil”. I find that when I do that I pay attention better, and record some things that I need to know later. I’ll take these notes, categorize them into a OneNote notebook that I synchronize in my Live.com account, and that way I can search them from anywhere. I can even read them on the web, since the Live.com has a OneNote program built in. Note that these are the raw notes, so they might not make a lot of sense out of context - I include them here so you can watch my though process. Programming Windows Azure by Siriram Krishnan: Learning about how to select applications suitable for Distributed Technology. Application Fabric gets the least attention; probably because it was newer at the time. Very clear (Chapter One) Good foundation Background and history, but not too much I normally arrange my descriptions differently, starting with the use-cases and moving to physicality, but this difference helps me. Interesting that I am reading this using Safari Books Online, which uses many of these concepts. Taught me some new aspects of a Hypervisor – very low-level information about the Azure Fabric (not to be confused with the Application Fabric feature) (Chapter Two) Good detail of what is included in the SDK. Even more is available now. CS = Cloud Service (Chapter 3) Place Storage info in the configuration file, since it can be streamed in-line with a running app. Ditto for logging, and keep separated configs for staging and testing. Easy-switch in and switch out.  (Chapter 4) There are two Runtime API’s, one of external and one for internal. Realizing how powerful this paradigm really is. Some places seem light, and to drop off but perhaps that’s best. Managing API is not charged, which is nice. I don’t often think about the price, until it comes to an actual deployment (Chapter 5) Csmanage is something I want to dig into deeper. API requires package moves to Blob storage first, so it needs a URL. Csmanage equivalent can be written in Unix scripting using openssl. Upgrades are possible, and you use the upgradeDomainCount attribute in the Service-Definition.csdef file  Always use a low-privileged account to test on the dev fabric, since Windows Azure runs in partial trust. Full trust is available, but can be dangerous and must be well-thought out. (Chapter 6) Learned how to run full CMD commands in a web window – not that you would ever do that, but it was an interesting view into those links. This leads to a discussion on hosting other runtimes (such as Java or PHP) in Windows Azure. I got an expanded view on this process, although this is where the book shows its age a little. Books can be a problem for Cloud Computing for this reason – things just change too quickly. Windows Azure storage is not eventually consistent – it is instantly consistent with multi-phase commit. Plumbing for this is internal, not required to code that. (Chapter 7) REST API makes the service interoperable, hybrid, and consistent across code architectures. Nicely done. Use affinity groups to keep data and code together. Side note: e-book readers need a common “notes” feature. There’s a decent quick description of REST in this chapter. Learned about CloudDrive code – PowerShell sample that mounts Blob storage as a local provider. Works against Dev fabric by default, can be switched to Account. Good treatment in the storage chapters on the differences between using Dev storage and Azure storage. These can be mitigated. No, blobs are not of any size or number. Not a good statement (Chapter 8) Blob storage is probably Azure’s closest play to Infrastructure as a Service (Iaas). Blob change operations must be authenticated, even when public. Chapters on storage are pretty in-depth. Queue Messages are base-64 encoded (Chapter 9) The visibility timeout ensures processing of message in a disconnected system. Order is not guaranteed for a message, so if you need that set an increasing number in the queue mechanism. While Queues are accessible via REST, they are not public and are secured by default. Interesting – the header for a queue request includes an estimated count. This can be useful to create more worker roles in a dynamic system. Each Entity (row) in the Azure Table service is atomic – all or nothing. (Chapter 10) An entity can have up to 255 Properties  Use “ID” for the class to indicate the key value, or use the [DataServiceKey] Attribute.  LINQ makes working with the Azure Table Service much easier, although Interop is certainly possible. Good description on the process of selecting the Partition and Row Key.  When checking for continuation tokens for pagination, include logic that falls out of the check in case you are at the last page.  On deleting a storage object, it is instantly unavailable, however a background process is dispatched to perform the physical deletion. So if you want to re-create a storage object with the same name, add retry logic into the code. Interesting approach to deleting an index entity without having to read it first – create a local entity with the same keys and apply it to the Azure system regardless of change-state.  Although the “Indexes” description is a little vague, it’s interesting to see a Folding and Stemming discussion a-la the Porter Stemming Algorithm. (Chapter 11)  Presents a better discussion of indexes (at least inverted indexes) later in the chapter. Great treatment for DBA’s in Chapter 11. We need to work on getting secondary indexes in Table storage. There is a limited form of transactions called “Entity Group Transactions” that, although they have conditions, makes a transactional system more possible. Concurrency also becomes an issue, but is handled well if you’re using Data Services in .NET. It watches the Etag and allows you to take action appropriately. I do not recommend using Azure as a location for secure backups. In fact, I would rather have seen the examples in (Chapter 12) go the other way, showing how data could be brought back to a local store as a DR or HA strategy. Good information on cryptography and so on even so. Chapter seems out of place, and should be combined with the Blob chapter.  (Chapter 13) on SQL Azure is dated, although the base concepts are OK.  Nice example of simple ADO.NET access to a SQL Azure (or any SQL Server Really) database.

  • Experience your music in a whole new way with Zune for PC

    - by Matthew Guay
    Tired of the standard Media Player look and feel, and want something new and innovative?  Zune offers a fresh, new way to enjoy your music, videos, pictures, and podcasts, whether or not you own a Zune device. Microsoft started out on a new multimedia experience for PCs and mobile devices with the launch of the Zune several years ago.  The Zune devices have been well received and noted for their innovative UI, and the Zune HD’s fluid interface is the foundation for the widely anticipated Windows Phone 7.  But regardless of whether or not you have a Zune Device, you can still use the exciting new UI and services directly from your PC.  Zune for Windows is a very nice media player that offers a music and video store and wide support for multimedia formats including those used in Apple products.  And if you enjoy listening to a wide variety of music, it also offers the Zune Pass which lets you stream an unlimited number of songs to your computer and download 10 songs for keeps per month for $14.99/month. Or you can do a pre-paid music card as well.  It does all this using the new Metro UI which beautifully shows information using text in a whole new way.  Here’s a quick look at setting up and using Zune on your PC. Getting Started Download the installer (link below), and run it to begin setup.  Please note that Zune offers a separate version for computers running the 64 bit version of Windows Vista or 7, so choose it if your computer is running these. Once your download is finished, run the installer to setup Zune on your computer.  Accept the EULA when prompted. If there are any updates available, they will automatically download and install during the setup.  So, if you’re installing Zune from a disk (for example, one packaged with a Zune device), you don’t have to worry if you have the latest version.  Zune will proceed to install on your computer.   It may prompt you to restart your computer after installation; click Restart Now so you can proceed with your Zune setup.  The reboot appears to be for Zune device support, and the program ran fine otherwise without rebooting, so you could possibly skip this step if you’re not using a Zune device.  However, to be on the safe side, go ahead and reboot. After rebooting, launch Zune.  It will play a cute introduction video on first launch; press skip if you don’t want to watch it. Zune will now ask you if you want to keep the default settings or change them.  Choose Start to keep the defaults, or Settings to customize to your wishes.  Do note that the default settings will set Zune as your default media player, so click Settings if you wish to change this. If you choose to change the default settings, you can change how Zune finds and stores media on your computer.  In Windows 7, Zune will by default use your Windows 7 Libraries to manage your media, and will in fact add a new Podcasts library to Windows 7. If your media is stored on another location, such as on a server, then you can add this to the Library.  Please note that this adds the location to your system-wide library, not just the Zune player. There’s one last step.  Enter three of your favorite artists, and Zune will add Smart DJ mixes to your Quickplay list based on these.  Some less famous or popular artists may not be recognized, so you may have to try another if your choice isn’t available.  Or, you can click Skip if you don’t want to do this right now. Welcome to Zune!  This is the default first page, QuickPlay, where you can easily access your pinned and new items.   If you have a Zune account, or would like to create a new one, click Sign In on the top. Creating a new account is quick and simple, and if you’re new to Zune, you can try out a 14 day trial of Zune Pass for free if you want. Zune allows you to share your listening habits and favorites with friends or the world, but you can turn this off or change it if you like. Using Zune for Windows To access your media, click the Collection link on the top left.  Zune will show all the media you already have stored on your computer, organized by artist and album. Right-click on any album, and you choose to have Zune find album art or do a variety of other tasks with the media.   When playing media, you can view it in several unique ways.  First, the default Mix view will show related tracks to the music you’re playing from Smart DJ.  You can either play these fully if you’re a Zune Pass subscriber, or otherwise you can play 30 second previews. Then, for many popular artists, Zune will change the player background to show pictures and information in a unique way while the music is playing.  The information may range from history about the artist to the popularity of the song being played.   Zune also works as a nice viewer for the pictures on your computer. Start a slideshow, and Zune will play your pictures with nice transition effects and music from your library. Zune Store The Zune Store offers a wide variety of music, TV shows, and videos for purchase.  If you’re a Zune Pass subscriber, you can listen to or download any song without purchasing it; otherwise, you can preview a 30 second clip first. Zune also offers a wide selection of Podcasts you can subscribe to for free. Using Zune for PC with a Zune Device If you have a Zune device attached to your computer, you can easily add media files to it by simply dragging them to the Zune device icon in the left corner.  In the future, this will also work with Windows Phone 7 devices. If you have a Zune HD, you can also download and add apps to your device. Here’s the detailed information window for the weather app.  Click Download to add it to your device.   Mini Mode The Zune player generally takes up a large portion of your screen, and is actually most impressive when run maximized.  However, if you’re simply wanting to enjoy your tunes while you’re using your computer, you can use the Mini mode to still view music info and control Zune in a smaller mode.  Click the Mini Player button near the window control buttons in the top right to activate it. Now Zune will take up much less of your desktop.  This window will stay on top of other windows so you can still easily view and control it. Zune will display an image of the artist if one is available, and this shows up in Mini mode more often than it does in the full mode. And, in Windows 7, you could simply minimize Zune as you can control it directly from the taskbar thumbnail preview.   Even more controls are available from Zune’s jumplist in Windows 7.  You can directly access your Quickplay links or choose to shuffle all music without leaving the taskbar. Settings Although Zune is designed to be used without confusing menus and settings, you can tweak the program to your liking from the settings panel.  Click Settings near the top left of the window. Here you can change file storage, types, burn, metadata, and many more settings.  You can also setup Zune to stream media to your XBOX 360 if you have one.   You can also customize Zune’s look with a variety of modern backgrounds and gradients. Conclusion If you’re ready for a fresh way to enjoy your media, Zune is designed for you.  It’s innovative UI definitely sets it apart from standard media players, and is very pleasing to use.  Zune is especially nice if your computer is using XP, Vista Home Basic, or 7 Starter as these versions of Windows don’t include Media Center.  Additionally, the mini player mode is a nice touch that brings a feature of Windows 7’s Media Player to XP and Vista.  Zune is definitely one of our favorite music apps.  Try it out, and get a fresh view of your music today!

  • Trying to find video of a talk on the impact of memory access latency

    - by user12889
    Some months ago I stumbled across a video on the internet of somebody giving a very good talk on the impact of memory access latency on the execution of programs. I'm trying to find the video again; maybe you know what video I mean and were I can find it. This is what I remember about the talk/video: I don't remember the title and it may have been broader, but the talk was a lot about impact of memory access latency in modern processors on program execution. The talk was in English and most likely the location was in America. The speaker was very knowledgeable about the topic, but the talk was in an informal setting (not a conference presentation or university lecture). I think the speaker was known to the audience and may even have been famous (I don't remember) The audience may have been a computer club / group of a local community or company (but I don't remember for sure)

  • Interview: how to ask development process/culture related questions

    - by davidk01
    I just watched a presentation about simplicity by Rich Hickey at InfoQ where he goes over the constructs programmers use to produce artifacts and how those constructs make various trade-offs when it comes to achieving simple artifacts. I think that most programmers would agree with a lot of what he says but at the end of the day I don't know how many development shops are actively practicing development processes and using tools that allow them to make simple artifacts. As an interview candidate I would like to work at a software development shop where producing simple artifacts is a top priority. What are some questions I can ask to figure out if the place that is interviewing me is actually such a place.
