• Windows using the DNS suffix search list on all lookups, even valid FQDNs. How to stop this?

  - by RealityGone

  When doing DNS lookups (specifically using nslookup, for some reason most things are not effected) Windows XP Pro SP3 is using the DNS suffix search list for every single one. Even for fully qualified domain names. For example I lookup "www.microsoft.com" but windows actually asks for "www.microsoft.com.eondream.com" (eondream.com is my primary domain). Now I can fix the issue by removing the Primary DNS suffix, but it seems to me that the DNS suffix search list should be for short, invalid names (where dots=0 or something). I'm sure I have a misconfiguration somewhere in windows but I don't know where. I've changed every option I can think of or find. Below is the output of ipconfig /all and nslookup (with debug & db2 enabled). This is using a static IP & (internal) DNS server. C:\ipconfig /all Windows IP Configuration Host Name . . . . . . . . . . . . : frayedlogic Primary Dns Suffix . . . . . . . : eondream.com Node Type . . . . . . . . . . . . : Unknown IP Routing Enabled. . . . . . . . : No WINS Proxy Enabled. . . . . . . . : No DNS Suffix Search List. . . . . . : eondream.com Ethernet adapter Wireless Network Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Dell Wireless 1390 WLAN Mini-Card Physical Address. . . . . . . . . : 00-1B-FC-29-EB-6B Dhcp Enabled. . . . . . . . . . . : No IP Address. . . . . . . . . . . . : 192.168.13.32 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.13.13 DNS Servers . . . . . . . . . . . : 192.168.19.19 C:\nslookup Default Server: shardik.eondream.com Address: 192.168.19.19 set debug set db2 www.microsoft.com Server: shardik.eondream.com Address: 192.168.19.19 ------------ Got answer: HEADER: opcode = QUERY, id = 2, rcode = NOERROR header flags: response, want recursion, recursion avail. questions = 1, answers = 1, authority records = 0, additional = 0 QUESTIONS: www.microsoft.com.eondream.com, type = A, class = IN ANSWERS: - www.microsoft.com.eondream.com internet address = 208.69.36.132 ttl = 0 (0 secs) ------------ Non-authoritative answer: Name: www.microsoft.com.eondream.com Address: 208.69.36.132 (Note: it resolves to that IP because I use the opendns service and that is their suggestion page or whatever you want to call it) If I am reading the nslookup output correctly then it is not a problem with my DNS server because windows is actually asking for the incorrect domain.

• SQLAuthority News – SafePeak’s SQL Server Performance Contest – Winners

  - by pinaldave

  SafePeak, the unique automated SQL performance acceleration and performance tuning software vendor, announced the winners of their SQL Performance Contest 2011. The contest quite unique: the writer of the best / most interesting and most community liked “performance story” would win an expensive gadget. The judges were the community DBAs that could participating and Like’ing stories and could also win expensive prizes. Robert Pearl SQL MVP, was the contest supervisor. I liked most of the stories and decided then to contact SafePeak and suggested to participate in the give-away and they have gladly accepted the same. The winner of best story is: Jason Brimhall (USA) with a story about a proc with a fair amount of business logic. Congratulations Jason! The 3 participants won the second prize of $100 gift card on amazon.com are: Michael Corey (USA), Hakim Ali (USA) and Alex Bernal (USA). And 5 participants won a printed copy of a book of mine (Book Reviews of SQL Wait Stats Joes 2 Pros: SQL Performance Tuning Techniques Using Wait Statistics, Types & Queues) are: Patrick Kansa (USA), Wagner Bianchi (USA), Riyas.V.K (India), Farzana Patwa (USA) and Wagner Crivelini (Brazil). The winners are welcome to send safepeak their mail address to receive the prizes (to “info ‘at’ safepeak.com”). Also SafePeak team asked me to welcome you all to continue sending stories, simply because they (and we all) like to read interesting stuff) as well as to send them ideas for future contests. You can do it from here: www.safepeak.com/SQL-Performance-Contest-2011/Submit-Story Congratulations to everybody! I found this very funny video about SafePeak: It looks like someone (maybe the vendor) played with video’s once and created this non-commercial like video: SafePeak dynamic caching is an immediate plug-n-play performance acceleration and scalability solution for cloud, hosted and business SQL server applications. By caching in memory result sets of queries and stored procedures, while keeping all those cache correct and up to date using unique patent pending technology, SafePeak can fix SQL performance problems and bottlenecks of most applications – most importantly: without actual code changes. By the way, I checked their website prior this contest announcement and noticed that they are running these days a special end year promotion giving between 30% to 45% discounts. Since the installation is quick and full testing can be done within couple of days – those have the need (performance problems) and have budget leftovers: I suggest you hurry. A free fully functional trial is here: www.safepeak.com/download, while those that want to start with a quote should ping here www.safepeak.com/quote. Good luck!

• Enhance GIMP’s Image Editing Power with Gimp Paint Studio

  - by Asian Angel

  Does your GIMP installation need a little super-charging? Using Gimp Paint Studio you can add a wonderful set of brushes, tools, and more to GIMP and take your work up to the next level. For our example we chose to install the beta version of Gimp Paint Studio on Ubuntu 10.10. Once you download the .zip file and unzip it, all that you need to do is manually transfer the contents shown here to the appropriate GIMP folders on your system. You can see the location of the destination folders here on our system… Note: Make certain to make a back-up copy of the “sessionrc and toolrc files” before you transfer Gimp Paint Studio into your installation (in case you would like to or need to revert back to the originals later). When you finish transferring the files start GIMP up and get ready to have fun. And if your experience is like ours then you should see a noticeable difference in window size and arrangement from the default settings. Here are some samples of the exceptional artwork done by Ramon Miranda and Mozart Couto using Gimp Paint Studio. Really impressive! Artwork by Ramon Miranda & Mozart Couto. Watch the introduction video and see Gimp Paint Studio in action.

• Grounded in Dublin

  - by Mike Dietrich

  Friday's hands-on workshop in the Oracle office in Dublin was quite good fun for everybody - except for Mick who has just recognized that his Ryanair flight back to Cork has been canceled (So I hope you've returned home well!) and me as my flights back to Munich via London City had been canceled as well. It's always good to have somebody in the workshop from Air Lingus so I've got hourly information what's going in in the Irish airspace (and now I know that the system dealing with such situations is an well prepared Oracle database which runs just like a switch watch - Thanks again for all your support!!! Was great to talk to you!!!). But to be honest, there are worse places to be grounded for a few days than Dublin. At least it gave me the chance to do something which I never had time enough before when visiting Oracle Ireland: a bit of sightseeing. When I've realized that nothing seems to move over the weekend I started organizing my travel back yesterday. It was no fun at all because there's no single system to book such a travel. Figuring out all possibilities and options going back to Munich was the first challange. Irish Ferries webpage was moaning with all the unexpected load (currently it's fully down). Hotel booking websites showed vacancies in Holyhead but didn't let me book. And calling them just reveiled that there are no rooms left. Haven't stayed overnight in a train station for quite a while ;-) The website of VirginTrains puzzled me with offering a seat at an enormous price for a train ride from Holyhead to London Euston (Thanks, Sir Richard Branson!) just to tell me after I booked a ticket that there are no seats left (but I traveled German railsways a few weeks ago from Düsseldorf to Frankfurt sitting on the floor as well). Eurostar's website let me choose tickets through the tunnel to tell me in the final step that the ticket cannot be confirmed as there are no seats left - but the next check again showed bookable seats - must be a database from some other vendor which has no proper row level locking ... hm ...?! Finally the TGV page for the speed train to Stuttgart and then the ICE to Munich was not allowing searches for quite a while - but ultimately ... after 4.5 hours of searching, waiting, sending credit card information again and again ... So if you have a few spare fingers please keep them crossed :-) And good luck to all my colleagues traveling back from the Exadata training in Berlin. As Mike Appleyard, my colleague from the UK presales team wrote: "Dublin and Berlin aren't too bad a place to get stuck... ;-)"

• Serious about Embedded: Java Embedded @ JavaOne 2012

  - by terrencebarr

  It bears repeating: More than ever, the Java platform is the best technology for many embedded use cases. Java’s platform independence, high level of functionality, security, and developer productivity address the key pain points in building embedded solutions. Transitioning from 16 to 32 bit or even 64 bit? Need to support multiple architectures and operating systems with a single code base? Want to scale on multi-core systems? Require a proven security model? Dynamically deploy and manage software on your devices? Cut time to market by leveraging code, expertise, and tools from a large developer ecosystem? Looking for back-end services, integration, and management? The Java platform has got you covered. Java already powers around 10 billion devices worldwide, with traditional desktops and servers being only a small portion of that. And the ‘Internet of Things‘ is just really starting to explode … it is estimated that within five years, intelligent and connected embedded devices will outnumber desktops and mobile phones combined, and will generate the majority of the traffic on the Internet. Is your platform and services strategy ready for the coming disruptions and opportunities? It should come as no surprise that Oracle is keenly focused on Java for Embedded. At JavaOne 2012 San Francisco the dedicated track for Java ME, Java Card, and Embedded keeps growing, with 52 sessions, tutorials, Hands-on-Labs, and BOFs scheduled for this track alone, plus keynotes, demos, booths, and a variety of other embedded content. To further prove Oracle’s commitment, in 2012 for the first time there will be a dedicated sub-conference focused on the business aspects of embedded Java: Java Embedded @ JavaOne. This conference will run for two days in parallel to JavaOne in San Francisco, will have its own business-oriented track and content, and targets C-level executives, architects, business leaders, and decision makers. Registration and Call For Papers for Java Embedded @ JavaOne are now live. We expect a lot of interest in this new event and space is limited, so be sure to submit your paper and register soon. Hope to see you there! Cheers, – Terrence Filed under: Mobile & Embedded Tagged: ARM, Call for Papers, Embedded Java, Java Embedded, Java Embedded @ JavaOne, Java ME, Java SE Embedded, Java SE for Embedded, JavaOne San Francisco, PowerPC

• [MISC GEEKERY] Lucid Lynx to Come Loaded with Ubuntu One Music Store

  - by Vivek

  Ubuntu 10.04 (code name Lucid Lynx) will come loaded with the Ubuntu One music store. Rhythmbox will have the Ubuntu One music store integrated in it. It’ll also allow users to download purchased music to their local machine. Ubuntu One Music Store Users will be able to access Ubuntu One music store from the sidebar of Rhythmbox. The music store is a web page that opens in the Rhythmbox player. There are albums listed on the home page of the Ubuntu One music store page. Ubuntu One music store is powered by 7digital, which is a leading digital B2B media delivery company based in London and operating globally. Canonical, the company behind Ubuntu, has partnered with 7digital to bring the music store to it’s users, integrating it with Rhythmbox and it’s cloud storage service UbuntuOne which was launched last year. The home screen of the Ubuntu One music store displays popular albums and functionality to browse and search. You can search for Artists, Tracks, Albums, or a combination of all three. Users will also be able to browse the store alphabetically, or based on different music genres. Once you select a specific artist, all their available albums are arranged in a grid. Once an album is selected, you’ll will be able to download specific songs or the whole album. You’ll also be allowed to preview different songs for 60 seconds. You’ll be able to buy tracks using a credit card or with PayPal. The purchased tracks will be visible under Library \ Purchased from Ubuntu One. The downloaded tracks are also synced with your UbuntuOne account. This means that you’ll be able to access your tracks from any where on the web. The default UbuntuOne account comes with 2 GB free storage, however, you can also purchase additional space if you need it.   All the music is in mp3 format which is not supported by default in Ubuntu. However, you can get mp3 playback functionality using GStreamer multimedia framework. Conclusion All in all the Ubuntu One music store is a positive move to enhance the user experience and also increase the popularity of Canonical in bringing Ubuntu closer to regular users. This would also provide Canonical to make some revenue in collaboration with 7digital.

• How to Quickly Cut a Clip From a Video File with Avidemux

  - by Trevor Bekolay

  Whether you’re cutting out the boring parts of your vacation video or getting a hilarious scene for an animated GIF, Avidemux provides a quick and easy way to cut clips from any video file. It’s overkill to use a full-featured video editing program if you just want to cut a few clips from a video file. Even programs that are designed to be small can have confusing interfaces when dealing with video. We’ve found that a great free program, Avidemux, makes the job of cutting clips extremely simple. Note: While the screenshots in this guide are taken from the Windows version, Avidemux runs on all of the major platforms – Windows, Mac OS X and Linux (GTK). Image by Keith Williamson. Cutting Clips from a Video File Open up Avidemux, and load the video file that you want to work with. If you get a prompt like this one: we recommend clicking Yes to use the safer mode. Find the portion of the video that you’d like to isolate. Get as close as you can to the start of the clip you want to cut. Once you find the start of your clip, look at the “Frame Type” of the current frame. You want it to read I; if it isn’t frame type I, then use the single left and right arrow buttons to go forward or backward one frame until you find an appropriate I frame. Once you’ve found the right starting frame, click the button with the A over a red bar. This will set the start of the clip. Advance to where you want your clip to end. Click on the button with a B when you’ve found the appropriate frame. This frame can be of any type. You can now save the clip, either by going to File –> Save –> Save Video… or by pressing Ctrl+S. Give the file a name, and Avidemux will prepare your clip. And that’s it! You should now have a movie file that contains only the portion of the original file that you want.

• An increase to 3 Gig of RAM slows down Ubuntu 10.04 LTS

  - by williepabon

  I have Ubuntu 10.04 running from an external hard drive (installed on an enclosure) connected via USB port. Like a month or so ago, I increased RAM on my pc from 2 Gigs to 3 Gigs. This resulted on extremely long boot times and slow application loads. While I was understanding the nature of my problem, I posted various threads on this forum ( Questions # 188417, 188801), where I was advised to gather speed tests, and other info on my machine. I was also suggested that I might have problems with the RAM installed. Initially, I did not consider that possibility because: 1) I did a memory test with a diagnostic program from DELL (My pc is from Dell) 2) My pc works fine with Windows XP (the default OS), no problems with memory 3) My pc works fine when booting with Ubuntu 10.10 memory stick, no speed problems 4) My pc works fine when booting with Ubuntu 11.10 memory stick, no speed problems Anyway, I performed the memory tests suggested. But before doing it, and to check out any possibility of hardware issues on the hard drive, I did the following: (1) purchased a new hard drive enclosure and moved my hard drive to it, (2) purchased a new USB cable and used it to connect my hard drive/enclosure setup to a different USB port on my pc. Then, I performed speed tests with 1 Gig, 2 Gigs and 3 Gigs of RAM with my Ubuntu 10.04 OS. Ubuntu 10.04 worked well when booted with 1 Gig or 2 Gigs of RAM. When I increased to 3 Gigs, it slowed down to a crawl. I can't understand the relationship between an increase of 1 Gig and the effect it has in Ubuntu 10.04. This doesn't happen with Ubuntu 10.10 and 11.10. Unfortunately for me, Ubuntu 10.04 is my principal work operating system. So, I need a solution for this. Hardware and system information: DELL Precision 670 2 internal SATA Hard drives Audigy 2 ZS audio system Factory OS: Windows XP Professional SP3 NVidia 8400 GTS video card More info: williepabon@WP-WrkStation:~$ uname -a Linux WP-WrkStation 2.6.32-38-generic #83-Ubuntu SMP Wed Jan 4 11:13:04 UTC 2012 i686 GNU/Linux williepabon@WP-WrkStation:~$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 10.04.4 LTS Release: 10.04 Codename: lucid Speed test with the 3 Gigs of RAM installed: williepabon@WP-WrkStation:~$ sudo hdparm -tT /dev/sdc [sudo] password for williepabon: /dev/sdc: Timing cached reads: 84 MB in 2.00 seconds = 41.96 MB/sec Timing buffered disk reads: 4 MB in 3.81 seconds = 1.05 MB/sec This is a very slow transfer rate from a hard drive. I will really appreciate a solution or a work around for this problem. I know that that there are users that have Ubuntu 10.04 with 3 Gigs or more of RAM and they don't have this problem. Same question asked on Launchpad for reference.

• Why is /dev/rfcomm0 giving PySerial problems?

  - by Travis G.

  I am connecting my Ubuntu box to a wireless readout setup over Bluetooth. I wrote a Python script to send the serial information through /dev/rfcomm0. The script connects fine and works for a few minutes, but then Python will start using 100% CPU and the messages stop flowing through. I can open rfcomm0 in a serial terminal and communicate through it by hand just fine. When I open it through a terminal it seems to work indefinitely. Also, I can swap the Bluetooth receiver for a USB cable, and change the port to /dev/ttyUSB0, and I don't get any problems over time. It seems either I'm doing something wrong with rfcomm0 or PySerial doesn't handle it well. Here's the script: import psutil import serial import string import time sampleTime = 1 numSamples = 5 lastTemp = 0 TEMP_CHAR = 't' USAGE_CHAR = 'u' SENSOR_NAME = 'TC0D' gauges = serial.Serial() gauges.port = '/dev/rfcomm0' gauges.baudrate = 9600 gauges.parity = 'N' gauges.writeTimeout = 0 gauges.open() print("Connected to " + gauges.portstr) filename = '/sys/bus/platform/devices/applesmc.768/temp2_input' def parseSensorsOutputLinux(output): return int(round(float(output) / 1000)) while(1): usage = psutil.cpu_percent(interval=sampleTime) gauges.write(USAGE_CHAR) gauges.write(chr(int(usage))) #write the first byte #print("Wrote usage: " + str(int(usage))) sensorFile = open(filename) temp = parseSensorsOutputLinux(sensorFile.read()) gauges.write(TEMP_CHAR) gauges.write(chr(temp)) #print("Wrote temp: " + str(temp)) Any thoughts? Thanks. EDIT: Here is the revised code, using Python-BlueZ instead of PySerial: import psutil import serial import string import time import bluetooth sampleTime = 1 numSamples = 5 lastTemp = 0 TEMP_CHAR = 't' USAGE_CHAR = 'u' SENSOR_NAME = 'TC0D' #gauges = serial.Serial() #gauges.port = '/dev/rfcomm0' #gauges.baudrate = 9600 #gauges.parity = 'N' #gauges.writeTimeout = 0 #gauges.open() gaugeSocket = bluetooth.BluetoothSocket(bluetooth.RFCOMM) gaugeSocket.connect(('00:06:66:42:22:96', 1)) filename = '/sys/bus/platform/devices/applesmc.768/temp2_input' def parseSensorsOutputLinux(output): return int(round(float(output) / 1000)) while(1): usage = psutil.cpu_percent(interval=sampleTime) #gauges.write(USAGE_CHAR) gaugeSocket.send(USAGE_CHAR) #gauges.write(chr(int(usage))) #write the first byte gaugeSocket.send(chr(int(usage))) #print("Wrote usage: " + str(int(usage))) sensorFile = open(filename) temp = parseSensorsOutputLinux(sensorFile.read()) #gauges.write(TEMP_CHAR) gaugeSocket.send(TEMP_CHAR) #gauges.write(chr(temp)) gaugeSocket.send(chr(temp)) #print("Wrote temp: " + str(temp)) It seems either Ubuntu must be closing /dev/rfcomm0 after a certain time or my Bluetooth receiver is messing things up. Even when the BluetoothError arises, the "connected" light on the receiver stays illuminated, and it is not until I power-cycle to receiver that I can reconnect. I'm not sure how to approach this problem. It's odd that the connection would work fine for a few minutes (seemingly a random amount of time) and then seize up. In case it helps, the Bluetooth receiver is a BlueSmirf Silver from Sparkfun. Do I need to be trying to maintain the connection from the receiver end or something?

• Claims-based Identity Terminology

  - by kaleidoscope

  There are several terms commonly used to describe claims-based identity, and it is important to clearly define these terms. · Identity In terms of Access Control, the term identity will be used to refer to a set of claims made by a trusted issuer about the user. · Claim You can think of a claim as a bit of identity information, such as name, email address, age, and so on. The more claims your service receives, the more you’ll know about the user who is making the request. · Security Token The user delivers a set of claims to your service piggybacked along with his or her request. In a REST Web service, these claims are carried in the Authorization header of the HTTP(S) request. Regardless of how they arrive, claims must somehow be serialized, and this is managed by security tokens. A security token is a serialized set of claims that is signed by the issuing authority. · Issuing Authority & Identity Provider An issuing authority has two main features. The first and most obvious is that it issues security tokens. The second feature is the logic that determines which claims to issue. This is based on the user’s identity, the resource to which the request applies, and possibly other contextual data such as time of day. This type of logic is often referred to as policy[1]. There are many issuing authorities, including Windows Live ID, ADFS, PingFederate from Ping Identity (a product that exposes user identities from the Java world), Facebook Connect, and more. Their job is to validate some credential from the user and issue a token with an identifier for the user's account and  possibly other identity attributes. These types of authorities are called identity providers (sometimes shortened as IdP). It’s ultimately their responsibility to answer the question, “who are you?” and ensure that the user knows his or her password, is in possession of a smart card, knows the PIN code, has a matching retinal scan, and so on. · Security Token Service (STS) A security token service (STS) is a technical term for the Web interface in an issuing authority that allows clients to request and receive a security token according to interoperable protocols that are discussed in the following section. This term comes from the WS-Trust standard, and is often used in the literature to refer to an issuing authority. STS when used from developer point of view indicates the URL to use to request a token from an issuer.

• Four Emerging Payment Stories

  - by David Dorf

  The world of alternate payments has been moving fast of late.  Innovation in this area will help both consumers and retailers, but probably hurt the banks (at least that's the plan).  Here are four recent news items in this area: Dwolla, a start-up in Iowa, is trying to make credit cards obsolete.  Twelve guys in Des Moines are using $1.3M they raised to allow businesses to skip the credit card networks and avoid the fees.  Today they move about $1M a day across their network with an average transaction size of $500. Instead of charging merchants 2.9% plus $.30 per transaction, Dwolla charges a quarter -- yep, that coin featuring George Washington. Dwolla (Web + Dollar = Dwolla) avoids the credit networks and connects directly to bank accounts using the bank's ACH network.  They are signing up banks and merchants targeting both B2B and C2B as well as P2P payments.  They leverage social networks to notify people they have a money transfer, and also have a mobile app that uses GPS location. However, all is not rosy.  There have been complaints about unexpected chargebacks and with debit fees being reduced by the big banks, the need is not as pronounced.  The big banks are working on their own network called clearXchange that could provide stiff competition. VeriFone just bought European payment processor Point for around $1B.  By itself this would not have caught my attention except for the fact that VeriFone also announced the acquisition of GlobalBay earlier this month.  In addition to their core business of selling stand-beside payment terminals, with GlobalBay they get employee-operated mobile selling tools and with Point they get a very big payment processing platform. MasterCard and Intel announced a partnership around payments, starting with PayPass, MasterCard's new payment technology.  Intel will lend its expertise to add additional levels of security, which seems to be the biggest barrier for consumer adoption.  Everyone is scrambling to get their piece of cash transactions, which still represents 85% of all transactions. Apple was awarded another mobile payment patent further cementing the rumors that the iPhone 5 will support NFC payments.  As usual, Apple is upsetting the apple cart (sorry) by moving control of key data from the carriers to Apple.  With Apple's vast number of iTunes accounts, they have a ready-made customer base to use the payment infrastructure, which I bet will slowly transition people away from credit cards and toward cheaper ACH.  Gary Schwartz explains the three step process Apple is taking to become a payment processor. Below is a picture I drew representing payments in the retail industry. There's certainly a lot of innovation happening.

• System crashes/lockups + compiz/cairo/gnome-panel crashing due to cached ram, please help?

  - by Kristian Thomson

  Can someone help me to troubleshoot system crashes and lockups which result in compiz/cairo dock and gnome-panel crashing? I also get no window borders after the crash and a lot of kernel memory errors. Logs are telling me that apps were killed due to not enough memory, but the system is caching like 14GB of my ram so I'm a bit stuck on what/how to stop it. I'm running Ubuntu 12.10 on a 2011 Mac Mini with 16 GB ram. Here's some of the logs that look like they could be causing trouble. I woke up this morning to find chrome/skype/cairo dock and a few others had been killed and here is what the log said. Nov 5 04:00:45 linkandzelda-Macmini kernel: [ 9310.959890] Out of memory: Kill process 12247 (chromium-browse) score 101 or sacrifice child Nov 5 04:00:45 linkandzelda-Macmini kernel: [ 9310.959893] Killed process 12247 (chromium-browse) total-vm:238948kB, anon-rss:17064kB, file-rss:20008kB Nov 5 04:00:45 linkandzelda-Macmini kernel: [ 9310.972283] Out of memory: Kill process 10976 (dropbox) score 3 or sacrifice child Nov 5 04:00:45 linkandzelda-Macmini kernel: [ 9310.972288] Killed process 10976 (dropbox) total-vm:316392kB, anon-rss:115484kB, file-rss:16504kB Nov 5 04:00:45 linkandzelda-Macmini kernel: [ 9310.975890] Out of memory: Kill process 10887 (rhythmbox) score 3 or sacrifice child Nov 5 04:00:45 linkandzelda-Macmini kernel: [ 9310.975895] Killed process 11515 (tray_icon_worke) total-vm:63336kB, anon-rss:15960kB, file-rss:11436kB Nov 5 04:00:45 linkandzelda-Macmini kernel: [ 9311.281535] Out of memory: Kill process 10887 (rhythmbox) score 3 or sacrifice child Nov 5 04:00:45 linkandzelda-Macmini kernel: [ 9311.281539] Killed process 10887 (rhythmbox) total-vm:528980kB, anon-rss:92272kB, file-rss:36520kB Nov 5 04:00:45 linkandzelda-Macmini kernel: [ 9311.283110] Out of memory: Kill process 10889 (skype) score 3 or sacrifice child Nov 5 04:00:45 linkandzelda-Macmini kernel: [ 9311.283113] Killed process 10889 (skype) total-vm:415056kB, anon-rss:84880kB, file-rss:22160kB I went to look deeper into things and saw that the whole time I'm having these kernel errors with out of memory and something mentioning radeon. I have a Radeon HD 6600M graphics card using the open source driver, not the proprietary one. I was wondering if perhaps using the proprietary one would solve the problem. Also, while writing this in Chrome rhythmbox and chrome just got killed while typing this, due to out of memory errors or so it reports, though I have 7 GB of free RAM at the time with 7 GB cached as well. Here is a full copy of my logs that happened in kern.log simply from when I began typing this question. http://pastebin.com/cdxxDktG Thanks in advance, Kris

• Apple iPad 2 In April, iPhone 5 in June With New Hardware[Rumours]

  - by Gopinath

  Blogs and news sites are buzzing with the rumours of Apple’s next generation iPad and iPhone devices. These rumours interests the bloggers, geeks and end users of Apple devices as Apple maintains very tight lip on the new features of their upcoming products. The gadget blog Engadget has some very interesting rumours on the release of iPad 2 & iPhone 5 as well the new hardware they are going to have. Lets get into the details if you love to read the rumours of high profile blogs iPad 2 Release Date and Specs Apple seems to be all set to release iPad 2 in April, that is almost an year after the release of first iPad. It’s common for Apple to enjoy an one year long time to release a new version of their products. So if at all the rumours are to be believed, I can place an order of iPad 2 in April. Just like many of you out there, I’m also holding my iPad buying instinct and waiting for iPad 2 as it’s going to have at the minimum retina display,  Facetime features and few game changing features in Apple’s style. The report claims, iPad 2 will have a front and back cameras retina display SD Card slot (seems to be no USB) a dual GSM / CDMA chipset, that lets you use it with both GSM(AT &T, Airte) and CDMA(Verizon, Reliance) telecom providers iPhone 5 Release Date and Specs When it comes to iPhone 5 information, the rumour claims that the new iPhone is a completed redesigned device and it’s slated to release in summer of United States(i.e. June 2011). The device is also being tested by senior Apple executives right inside the campus and strictly not allowed to carry it outside. This restriction is to make sure that iPhone 5 will not land land up in a bar and then in the hands of geek blogs like how it happened with iPhone 4 last year. When it comes to the hardware of iPhone 5 Apple’s new A5 CPU (a Cortex A9-based, multi-core chip) a dual GSM / CDMA chipset, that lets you use it with both GSM(AT &T, Airte) and CDMA(Verizon, Reliance) telecom providers via Engadget and cc image credit flickr/mr-blixt This article titled,Apple iPad 2 In April, iPhone 5 in June With New Hardware[Rumours], was originally published at Tech Dreams.

• Should I be using a JavaScript SPA designed when security is important

  - by ryanzec

  I asked something kind of similar on stackoverflow with a particular piece of code however I want to try to ask this in a broader sense. So I have this web application that I have started to write in backbone using a Single Page Architecture (SPA) however I am starting to second guess myself because of security. Now we are not storing and sending credit card information or anything like that through this web application but we are storing sensitive information that people are uploading to us and will have the ability to re-download too. The obviously security concern that I have with JavaScript is that you can't trust anything that comes from JavaScript however in a Backbone SPA application, everything is being sent through JavaScript. There are two security features that I will have to build in JavaScript; permissions and authentication. The authentication piece is just me override the Backbone.Router.prototype.navigate method to check the fragment it is trying to load and if the JavaScript application.session.loggedIn is not set to true (and they are not viewing a none authenticated page), they are redirected to the login page automatically. The user could easily modify application.session.loggedIn to equal true (or modify Backbone.Router.prototype.navigate method) but then they would also have to not so easily dynamically embedded a link into the page (or modify a current one) that has the proper classes, data-* attributes, and href values to then load a page that should only be loaded when they user has logged in (and has the permissions). So I have an acl object that deals with the permissions stuff. All someone would have to do to view pages or parts of pages they should not be able to is to call acl.addPermission(resource, permission) with the proper permissions or modify the acl.hasPermission() to always return true and then navigate away and then back to the page. Now certain things is EMCAScript 5 like Object.seal() or Object.freeze() would help with some of this however we have to support IE 8 which does not support those pieces of functionality. Now the REST API also performs security checks on every request so technically even if they are able to see parts of the interface that they should not be able to, they still should not be able to actually affect any data. The main benefits for me in developing a JavaScript SPA application is that the application is a lot more responsive since it is only transferring the minimum amount of JSON data for the requested action and performing the minimum amount of work too. There are also other things that I think are beneficial like you are going to have to develop an API for the data (which is good if you want expand your application to different platforms/technologies) or their is more of a separation between front-end and back-end however if security is a concern, it is really wise to go down the road of a JavaScript SPA application for the front-end?

• Site Studio Mobile Example - WCM Reuse

  - by john.brunswick

  Mobile internet usage is growing by leaps and bounds and it is theorized that in the not-to-distant future it will eclipse traditional access via desktop browsers. Mary Meeker, a managing director at Morgan Stanley and head of their global technology research team, recently predicted that mobile usage will eclipse desktop usage within the next 5 years in an Events@Google series presentation. In order for organizations to reach their prospects, customers and business partners, they will need to make their content readily available on mobile devices. A few years ago it was fairly challenging to provide a special, separate, site to cater to mobile users using technologies like WML (Wireless Markup Language). Modern mobile browsers have rendered the need for this as irrelevant and now the focus has moved toward providing a browsing experience that works well on small screen sizes and is highly performant. What does all of this mean for Oracle UCM? Taking site content from an existing Site Studio site and targeting it for consumption for mobile devices is a very straightforward process that is aided by a number of native capabilities in the product. The example highlighted in this post takes advantage of dynamic conversion capabilities in Oracle UCM to enable site content to be created and updated via MS Office documents. These documents are then converted to a simple, clean HTML format for consumption in the desktop and mobile browsing experiences. To help better understand how this is possible the example below shows a fictional .COM and its mobile site counterpart that both leverage the same underlying content. The scenario is not complete or production ready, but highlights that a mobile experience may be best delivered by omitting portions of a site that would be present within the version served to desktop clients. If you have browsed CNet (news.com) on a mobile device it becomes quickly apparent that they are serving an optimized version for your mobile device. An iPhone style version can be accessed at http://iphone.cnet.com/. In order to do that they leveraged some work done for the iPhone iUi project developed by Joe Hewitt that provides mobile browsers an experience that is similar to what users may find in a native iPhone application. For our example parts of this framework are used (the CSS) and this approach provides a page that will degrade nicely over a wide range of mobile browsers, since it is comprised of lightweight HTML markup and CSS. The iPhone iUi framework also provides some nice JavaScript to enable animated transitions between pages, but for the widest range of mobile browser compatibility we will only incorporate the CSS and HTML DIV / UL based page markup in our example.

• FREE Windows Azure evening in London on April 15th including FREE access to Windows Azure

  - by Eric Nelson

  [Did I overdo the use of FREE in the title? :-)] April 12th to 16th is Microsoft Tech Days – 5 days of sessions on Visual Studio 2010 through to Windows 7 Phone Series. Many of these days are now full (Tip - Thursday still has room if rich client applications is your thing) but the good news is the development community in the UK has pulled together an awesome series of “fringe events” during April in London and elsewhere in the UK. There are sessions on Silverlight, SQL Server 2008 R2, Sharepoint 2010 and … the Windows Azure Platform. The UK AzureNET user group is planning to put on a great evening and AzureNET will be giving away hundreds of free subscriptions to the Windows Azure Platform during the evening. The subscription includes up to 20 Windows Azure Compute nodes and 3 SQL Azure databases for you to play with over the 2 weeks following the event. This is a great opportunity to really explore the Windows Azure Platform in detail – without a credit card! Register now! (and you might also want to join the UK Fans of Azure Community while I have your attention) FYI The Thursday day time event includes an introduction to Windows Azure session delivered by my colleague David – which would be an ideal session to attend if you are new to Azure and want to get the most out of the evening session. 7:00pm: See the difference: How Windows Azure helped build a new way of giving Simon Evans and James Broome (@broomej) They will cover the business context for Azure and then go into patterns used and lessons learnt from the project....as well as showing off the app of course! 8:00pm: UK AzureNET update 8:15pm: NoSQL databases or: How I learned to love the hash table Mark Rendle (@markrendle) In this session Mark will look at how Azure Table Service works and how to use it. We’ll look briefly at the high-level Data Services SDK, talk about its limitations, and then quickly move on to the REST API and how to use it to improve performance and reduce costs. We’ll make-up some pretend real-world problems and solve them in new and interesting ways. We’ll denormalise data (for fun and profit). We’ll talk about how certain social networking sites can deal with huge volumes of data so quickly, and why it sometimes goes wrong. Check out the complete list of fringe events which covers the UK fairly well:

• How to setup Dual Head with "radeon" driver for R770?

  - by user1709408

  I want to make dual head setup without xrandr but with Xinerama. I put "Screen 1" line into xorg.conf, but card still show identical output on DVI-2 and DVI-3 It is important to use xinerama for me (to glue three monitors), that's why i decide not to use ranrd (randr is incompatible with xinerama as i read somewhere) Here is my videocard (HD 4850 X2): lspci | grep R700 03:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI R700 [Radeon HD 4850] 04:00.0 Display controller: Advanced Micro Devices [AMD] nee ATI R700 [Radeon HD 4850] Here is how monitors are connected: grep "DVI" /var/log/Xorg.0.log [ 1210.002] (II) RADEON(0): Output DVI-0 using monitor section Monitor0 [ 1210.048] (II) RADEON(0): Output DVI-1 has no monitor section [ 1210.079] (II) RADEON(0): EDID for output DVI-0 [ 1210.080] (II) RADEON(0): Printing probed modes for output DVI-0 [ 1210.128] (II) RADEON(0): EDID for output DVI-1 [ 1210.128] (II) RADEON(0): Output DVI-0 connected [ 1210.128] (II) RADEON(0): Output DVI-1 disconnected [ 1210.128] (II) RADEON(0): Output DVI-0 using initial mode 1920x1200 [ 1210.160] (II) RADEON(1): Output DVI-2 using monitor section Monitor2 [ 1210.215] (II) RADEON(1): Output DVI-3 has no monitor section [ 1210.246] (II) RADEON(1): EDID for output DVI-2 [ 1210.247] (II) RADEON(1): Printing probed modes for output DVI-2 [ 1210.299] (II) RADEON(1): EDID for output DVI-3 [ 1210.300] (II) RADEON(1): Printing probed modes for output DVI-3 [ 1210.300] (II) RADEON(1): Output DVI-2 connected [ 1210.300] (II) RADEON(1): Output DVI-3 connected [ 1210.300] (II) RADEON(1): Output DVI-2 using initial mode 1920x1200 [ 1210.300] (II) RADEON(1): Output DVI-3 using initial mode 1920x1200 Here is my /etc/X11/xorg.conf Section "ServerFlags" Option "RandR" "0" Option "Xinerama" "1" EndSection Section "ServerLayout" Identifier "Three Head Layout" Screen "MyPrecious0" Screen "MyPrecious2" RightOf "MyPrecious0" Screen "MyPrecious3" LeftOf "MyPrecious0" EndSection Section "Screen" Identifier "MyPrecious0" Monitor "Monitor0" Device "Device300" EndSection Section "Screen" Identifier "MyPrecious2" Monitor "Monitor2" Device "Device400" EndSection Section "Screen" Identifier "MyPrecious3" Monitor "Monitor3" Device "Device401" EndSection Section "Device" Identifier "Device300" BusID "PCI:3:0:0" Screen 0 Driver "radeon" EndSection Section "Device" Identifier "Device400" BusID "PCI:4:0:0" Screen 0 Driver "radeon" EndSection Section "Device" Identifier "Device401" BusID "PCI:4:0:0" Screen 1 Driver "radeon" EndSection Section "Monitor" Identifier "Monitor0" EndSection Section "Monitor" Identifier "Monitor2" EndSection Section "Monitor" Identifier "Monitor3" EndSection I tried to switch to vesa driver (didn't work for me) I tried to add options like Option "ZaphodHeads" "DVI-2" and Option "ZaphodHeads" "DVI-3" into sections "Device 400" and "Device 401" (this didn't help because "ZaphodHeads" option is for ranrd, and randr is disabled by decision) I tried to merge sections "Device 400" and "Device 401" into one section and add Option "ZaphodHeads" "DVI-2,DVI-3" (see comment about randr above) single section setup helps to change log line RADEON(1): Output DVI-3 has no monitor section into RADEON(1): Output DVI-3 using monitor section Monitor3 but nothing was enough to switch from screen cloning to separate screens. This problem (lack of documentation on radeon driver) is similar to these: Radeon display driver clones monitors while using Xinerama (moderators decision to close that problem was wrong) Ubuntu 12.10 multi-monitor setup isn't working The problem is solvable, because this hardware worked as three headed for me earlier with gentoo/xorg-server-1.3 Xorg -configure creates setup for the first monitor on the first GPU Please don't advise to use fglrx/aticonfig/amdcccle (this goes against my religion beliefs)

• Nokia vs. The World

  - by Michael B. McLaughlin

  I’m looking forward to the launch of the Nokia Lumia 920. Why? Well, it stacks up better than the competition for one thing. Then there’s also that security problem that certain other phones have. Mostly, though, it’s because I love my Lumia 900 and the 920, with Windows Phone 8, will be even better. Before I got my Lumia 900, I just took it as given that smart phone cameras couldn’t be good. The Lumia taught me that smart phone cameras can be good if the manufacturer treats them as an important component worth spending time and money on (rather than some thing that consumers expect such that they’d better throw one in). I’m extremely pleased with the quality of pictures that my Lumia 900 gives me as well as the range of settings it provides (you can delve in to tell it a film speed, an f-stop, and a whole range of other settings). And the image stabilization features in the Lumia 920 deliver far better results than the others. Nokia has had great maps for a long time and they continue to improve. Even better, they made a deal that puts many of their excellent maps into Windows Phone 8 itself. There are still Nokia-exclusive features such as Nokia City Lens, of course. But by giving the core OS a great set of fundamental map data and technologies, they help ensure that customers know that buying a Windows Phone 8 will give them a great map experience no matter who made the phone. I’ll be getting a 920, myself, but the HTC and Samsung devices that have been announced have some compelling features, too, and it’s great to know that people who buy one of these won’t need to worry about where their maps might lead them. I’m looking forward to the NFC capabilities and Qi wireless charging my Lumia 920 will have. With the availability of DirectX and C++ programming on Windows Phone 8, I’m also excited about all the great games that will be added to the Windows Phone environment. I love my Xbox Phone. I love my Office phone. I love my Facebook phone. I love my GPS phone. I love my camera phone. I love my SkyDrive phone. In short, I love my Windows Phone!
