• DIA2012

  - by Chris Kawalek

  If you've read this blog before, you probably know that Oracle desktop virtualization is used to demonstrate Oracle Applications at many different trade shows. This week, the Oracle desktop team is at DIA2012 in Philadelphia, PA. The DIA conference is a large event, hosting about 7,000 professionals in the pharmaceutical, bio technology, and medical device fields. Healthcare and associated fields are leveraging desktop virtualization because the model is a natural fit due to their high security requirements. Keeping all the data on the server and not distributing it on laptops or PCs that could be stolen makes a lot of sense when you're talking about patient records and other sensitive information. We're proud to be supporting the Oracle Health Sciences team at DIA2012 by hosting all of the Oracle healthcare related demos on a central server, and providing simple, smart card based access using our Sun Ray Clients. And remember that you're not limited to using just Sun Ray Clients--you can also use the Oracle Virtual Desktop Client and freely move your session from your iPad, your Windows or Linux PC, your Mac, or Sun Ray Clients. It's a truly mobile solution for an industry that requires mobile, secure access in order to remain compliant. Here are some pics from the show: We also have an informative PDF on Oracle desktop virtualization and Oracle healthcare that you can have a look at.  (Many thanks to Adam Workman for the pics!) -Chris  For more information, please go to the Oracle Virtualization web page, or  follow us at :  Twitter   Facebook YouTube Newsletter

• Is taking a semester or year off from college a good idea?

  - by astrieanna

  I am currently a Junior majoring in Computer Science at a top university (in the USA). As I'm really getting tired of taking classes, I was wondering if taking a semester or year off to do an internship(s) is a reasonable idea? It seems like it would give me more experience programming (making classes a bit easier), and give me a chance to recover from the burnout that comes from taking 18 credits a semester. A friend suggested that I just take a lighter course load, but I only have 2 more semesters of financial aid, so I need to take 18 credits in each of them in order to finish. Taking time off from school is not a normal thing to do, at least at this school. Since more internships are advertised for the summer (that I've seen), I was wondering if there are internships available in times other than the summer? If I took off for a whole year, would it be more valuable to try to stay at the same company for the whole time or to try to get a series of internships at different ones? Valuable in both the sense of resume value and personal value. Would it be easier or harder to get multiple shorter internships?

• Should a programmer "think" for the client?

  - by P.Brian.Mackey

  I have gotten to the point where I hate requirements gathering. Customer's are too vague for their own good. In an agile environment, where we can show the client a piece of work to completion it's not too bad as we can make small regular corrections/updates to functionality. In a "waterfall" type in environment (requirements first, nearly complete product next) things can get ugly. This kind of environment has led me to constantly question requirements. E.G. Customer wants "automatically convert input to the number 1" (referring to a Qty in an order). But what they don't think about is that "input" could be a simple type-o. An "x" in a textbox could be a "woops" not I want 1 of those "toothpaste" products. But, there's so much in the air with requirements that I could stand and correct for hours on end smashing out what they want. This just isn't healthy. Working for a corporation, I could try to adjust the culture to fit the agile model that would help us (no small job, above my pay grade). Or, sweep ugly details under the rug and hope for the best. Maybe my customer is trying to get too close to the code? How does one handle the problem of "thinking for the client" without pissing them off with too many questions?

• SQL query duplicating results [on hold]

  - by Ben

  I have written a query that results in data being retrieved for the top 5 customers in my table per account manager. Here is the query: SELECT account_manager_id, mgap_ska_id, total FROM (SELECT account_manager_id, mgap_ska_id, mgap_growth + mgap_recovery AS total, @grp_rank := IF(@current_accmanid = account_manager_id, @grp_rank + 1, 1) AS grp_rank, @current_accmanid := account_manager_id FROM mgap_orders ORDER BY total DESC ) ranked WHERE grp_rank <= 5 and here is the result of the query: account_manager_id mgap_ska_id total 159840 5062352 61569.21 159840 5062352 61569.21 159840 5062352 61569.21 159840 5062352 61569.21 159840 5062352 61569.21 160023 5024546 52244.29 160023 5024546 52244.29 160023 5024546 52244.29 160023 5024546 52244.29 160023 5024546 52244.29 159669 5323292 50126.38 159669 5323292 50126.38 159669 5323292 50126.38 159669 5323292 50126.38 159669 5323292 50126.38 As you can see the query is partially working as needed, except Im getting duplicates for mgap_ska_id whereas it should be five individual mgap_ska_id numbers. and here is a sample of my data: mgap_ska_id account_manager_id mgap_growth mgap_recovery 5057810 64154 0 1160.78 5178114 24456 0 5773.42 5292421 160338 0 5146.04 5414091 24408 0 104.14 5057810 64154 0 1160.78 Can anyone see where Ive gone wrong in my query and how/where I might correct the error so I get the 5 top individual customers (mgap_ska_id) instead of the duplicated top single customer?

• How can I set the fan speed to 100% on a laptop?

  - by Codemonkey

  I recently purchased a HP Pavilion dv7-4031. When it's cool, it works smoothly and efficiently. However when CPU and GUP temperatures reach 60c and above, the PC starts freezing up and stuttering. I can hear that the fan speeds steadily increase all the way up to 70-80c. This is what pisses me off: I want the fan speeds to run 100% all the time, perhaps preventing the high temperatures in the first place. The way it is now, fan speeds only increase to keep internal temperatures at above 60c. I've searched all over for any sort of speed control, finding nothing. Any help appreciated. I have tried Speedfan. In "Fans" there is nothing listed. I took that as a bad sign. The BIOS is pathetic, and only has 4 or 5 changeable settings, including "Quickstart" and "Boot order"

• Log Blog

  - by PointsToShare

  © 2011 By: Dov Trietsch. All rights reserved Logging – A log blog In a another blog (Missing Fields and Defaults) I spoke about not doing a blog about log files, but then I looked at it again and realized that this is a nice opportunity to show a simple yet powerful tool and also deal with static variables and functions in C#. My log had to be able to answer a few simple logging rules:   To log or not to log? That is the question – Always log! That is the answer  Do we share a log? Even when a file is opened with a minimal lock, it does not share well and performance greatly suffers. So sharing a log is not a good idea. Also, when sharing, it is harder to find your particular entries and you have to establish rules about retention. My recommendation – Do Not Share!  How verbose? Your log can be very verbose – a good thing when testing, very terse – a good thing in day-to-day runs, or somewhere in between. You must be the judge. In my Blog, I elect to always report a run with start and end times, and always report errors. I normally use 5 levels of logging: 4 – write all, 3 – write more, 2 – write some, 1 – write errors and timing, 0 – write none. The code sample below is more general than that. It uses the config file to set the max log level and each call to the log assigns a level to the call itself. If the level is above the .config highest level, the line will not be written. Programmers decide which log belongs to which level and thus we can set the .config differently for production and testing.  Where do I keep the log? If your career is important to you, discuss this with the boss and with the system admin. We keep logs in the L: drive of our server and make sure that we have a directory for each app that needs a log. When adding a new app, add a new directory. The default location for the log is also found in the .config file Print One or Many? There are two options here:   1.     Print many, Open but once once – you start the stream and close it only when the program ends. This is what you can do when you perform in “batch” mode like in a console app or a stsadm extension.The advantage to this is that starting a closing a stream is expensive and time consuming and because we use a unique file, keeping it open for a long time does not cause contention problems. 2.     Print one entry at a time or Open many – every time you write a line, you start the stream, write to it and close it. This work for event receivers, feature receivers, and web parts. Here scalability requires us to create objects on the fly and get rid of them as soon as possible.  A default value of the onceOrMany resides in the .config.  All of the above applies to any windows or web application, not just SharePoint.  So as usual, here is a routine that does it all, and a few simple functions that call it for a variety of purposes.   So without further ado, here is app.config  <?xml version="1.0" encoding="utf-8" ?> <configuration>     <configSections>         <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=2.0.0.0, Culture=neutral, ublicKeyToken=b77a5c561934e089" >         <section name="statics.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />         </sectionGroup>     </configSections>     <applicationSettings>         <statics.Properties.Settings>             <setting name="oneOrMany" serializeAs="String">                 <value>False</value>             </setting>             <setting name="logURI" serializeAs="String">                 <value>C:\staticLog.txt</value>             </setting>             <setting name="highestLevel" serializeAs="String">                 <value>2</value>             </setting>         </statics.Properties.Settings>     </applicationSettings> </configuration>   And now the code:  In order to persist the variables between calls and also to be able to persist (or not to persist) the log file itself, I created an EventLog class with static variables and functions. Static functions do not need an instance of the class in order to work. If you ever wondered why our Main function is static, the answer is that something needs to run before instantiation so that other objects may be instantiated, and this is what the “static” Main does. The various logging functions and variables are created as static because they do not need instantiation and as a fringe benefit they remain un-destroyed between calls. The Main function here is just used for testing. Note that it does not instantiate anything, just uses the log functions. This is possible because the functions are static. Also note that the function calls are of the form: Class.Function.  using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; namespace statics {       class Program     {         static void Main(string[] args)         {             //write a single line             EventLog.LogEvents("ha ha", 3, "C:\\hahafile.txt", 4, true, false);             //this single line will not be written because the msgLevel is too high             EventLog.LogEvents("baba", 3, "C:\\babafile.txt", 2, true, false);             //The next 4 lines will be written in succession - no closing             EventLog.LogLine("blah blah", 1);             EventLog.LogLine("da da", 1);             EventLog.LogLine("ma ma", 1);             EventLog.LogLine("lah lah", 1);             EventLog.CloseLog(); // log will close             //now with specific functions             EventLog.LogSingleLine("one line", 1);             //this is just a test, the log is already closed             EventLog.CloseLog();         }     }     public class EventLog     {         public static string logURI = Properties.Settings.Default.logURI;         public static bool isOneLine = Properties.Settings.Default.oneOrMany;         public static bool isOpen = false;         public static int highestLevel = Properties.Settings.Default.highestLevel;         public static StreamWriter sw;         /// <summary>         /// the program will "print" the msg into the log         /// unless msgLevel is > msgLimit         /// onceOrMany is true when once - the program will open the log         /// print the msg and close the log.

• 802.11 Capture Frame

  - by ALi

  I am using wireshark in monitor mode to capture all the frame. I buffered all the QosData in order to calculate the biterate of each station on the network. I calculate the biterate but it is not an accurate value. what i need to know is when the station use the network alone and when it uses it with another station? i know if two station with different wifi card for exemple ( st1 802.11g 54 Mb/s, st2 802.11n 300 Mb/s) if st1 uses alone the line the biterate used is 28 MB/s and if st2 uses alone the network the bit rate increase to approximately 150Mb/s but if the two station use the network at the same time the st1 lost about 80% of its bit rate because of the st1 wifi card thx in advance

• Real tortoises keep it slow and steady. How about the backups?

  - by Maria Zakourdaev

    … Four tortoises were playing in the backyard when they decided they needed hibiscus flower snacks. They pooled their money and sent the smallest tortoise out to fetch the snacks. Two days passed and there was no sign of the tortoise. "You know, she is taking a lot of time", said one of the tortoises. A little voice from just out side the fence said, "If you are going to talk that way about me I won't go." Is it too much to request from the quite expensive 3rd party backup tool to be a way faster than the SQL server native backup? Or at least save a respectable amount of storage by producing a really smaller backup files?  By saying “really smaller”, I mean at least getting a file in half size. After Googling the internet in an attempt to understand what other “sql people” are using for database backups, I see that most people are using one of three tools which are the main players in SQL backup area:  LiteSpeed by Quest SQL Backup by Red Gate SQL Safe by Idera The feedbacks about those tools are truly emotional and happy. However, while reading the forums and blogs I have wondered, is it possible that many are accustomed to using the above tools since SQL 2000 and 2005.  This can easily be understood due to the fact that a 300GB database backup for instance, using regular a SQL 2005 backup statement would have run for about 3 hours and have produced ~150GB file (depending on the content, of course).  Then you take a 3rd party tool which performs the same backup in 30 minutes resulting in a 30GB file leaving you speechless, you run to management persuading them to buy it due to the fact that it is definitely worth the price. In addition to the increased speed and disk space savings you would also get backup file encryption and virtual restore -  features that are still missing from the SQL server. But in case you, as well as me, don’t need these additional features and only want a tool that performs a full backup MUCH faster AND produces a far smaller backup file (like the gain you observed back in SQL 2005 days) you will be quite disappointed. SQL Server backup compression feature has totally changed the market picture. Medium size database. Take a look at the table below, check out how my SQL server 2008 R2 compares to other tools when backing up a 300GB database. It appears that when talking about the backup speed, SQL 2008 R2 compresses and performs backup in similar overall times as all three other tools. 3rd party tools maximum compression level takes twice longer. Backup file gain is not that impressive, except the highest compression levels but the price that you pay is very high cpu load and much longer time. Only SQL Safe by Idera was quite fast with it’s maximum compression level but most of the run time have used 95% cpu on the server. Note that I have used two types of destination storage, SATA 11 disks and FC 53 disks and, obviously, on faster storage have got my backup ready in half time. Looking at the above results, should we spend money, bother with another layer of complexity and software middle-man for the medium sized databases? I’m definitely not going to do so.  Very large database As a next phase of this benchmark, I have moved to a 6 terabyte database which was actually my main backup target. Note, how multiple files usage enables the SQL Server backup operation to use parallel I/O and remarkably increases it’s speed, especially when the backup device is heavily striped. SQL Server supports a maximum of 64 backup devices for a single backup operation but the most speed is gained when using one file per CPU, in the case above 8 files for a 2 Quad CPU server. The impact of additional files is minimal.  However, SQLsafe doesn’t show any speed improvement between 4 files and 8 files. Of course, with such huge databases every half percent of the compression transforms into the noticeable numbers. Saving almost 470GB of space may turn the backup tool into quite valuable purchase. Still, the backup speed and high CPU are the variables that should be taken into the consideration. As for us, the backup speed is more critical than the storage and we cannot allow a production server to sustain 95% cpu for such a long time. Bottomline, 3rd party backup tool developers, we are waiting for some breakthrough release. There are a few unanswered questions, like the restore speed comparison between different tools and the impact of multiple backup files on restore operation. Stay tuned for the next benchmarks.    Benchmark server: SQL Server 2008 R2 sp1 2 Quad CPU Database location: NetApp FC 15K Aggregate 53 discs Backup statements: No matter how good that UI is, we need to run the backup tasks from inside of SQL Server Agent to make sure they are covered by our monitoring systems. I have used extended stored procedures (command line execution also is an option, I haven’t noticed any impact on the backup performance). SQL backup LiteSpeed SQL Backup SQL safe backup database <DBNAME> to disk= '\\<networkpath>\par1.bak' , disk= '\\<networkpath>\par2.bak', disk= '\\<networkpath>\par3.bak' with format, compression EXECUTE master.dbo.xp_backup_database @database = N'<DBName>', @backupname= N'<DBName> full backup', @desc = N'Test', @compressionlevel=8, @filename= N'\\<networkpath>\par1.bak', @filename= N'\\<networkpath>\par2.bak', @filename= N'\\<networkpath>\par3.bak', @init = 1 EXECUTE master.dbo.sqlbackup '-SQL "BACKUP DATABASE <DBNAME> TO DISK= ''\\<networkpath>\par1.sqb'', DISK= ''\\<networkpath>\par2.sqb'', DISK= ''\\<networkpath>\par3.sqb'' WITH DISKRETRYINTERVAL = 30, DISKRETRYCOUNT = 10, COMPRESSION = 4, INIT"' EXECUTE master.dbo.xp_ss_backup @database = 'UCMSDB', @filename = '\\<networkpath>\par1.bak', @backuptype = 'Full', @compressionlevel = 4, @backupfile = '\\<networkpath>\par2.bak', @backupfile = '\\<networkpath>\par3.bak' If you still insist on using 3rd party tools for the backups in your production environment with maximum compression level, you will definitely need to consider limiting cpu usage which will increase the backup operation time even more: RedGate : use THREADPRIORITY option ( values 0 – 6 ) LiteSpeed : use  @throttle ( percentage, like 70%) SQL safe :  the only thing I have found was @Threads option.   Yours, Maria

• Multiple sites with the same codebase in Python

  - by Jimmy

  I am trying to run a large amount of sites which share about 90% of their code. They are simply designed to query an API and return the results. They will have a common userbase / database but will be configured slightly different and will have different CSS (perhaps even different templating). My initial idea was to run them as separate applications with a common library but I have read about the sites framework which would allow them to run from a single instance of Django which may help to reduce memory usage. https://docs.djangoproject.com/en/dev/ref/contrib/sites/ Is the site framework the right approach to a problem like this, and does it have real benefits over running separate applications? Initially I thought it was, but now I think otherwise. I have heard the following: Your SITE_ID is set in settings.py, so in order to have multiple sites, you need multiple settings.py configurations, which means multiple distinct processes/instances. You can of course share the code base between them, but each site will need a dedicated worker / WSGIDaemon to serve the site. This effectively removes any benefit of running multiple sites under one hood, if each site needs a UWSGI instance running. Alternative ideas of systems: https://github.com/iivvoo/django_layers https://github.com/shestera/django-multisite I don't know what route to be taking with this.

• Performance of concurrent software on multicore processors

  - by Giorgio

  Recently I have often read that, since the trend is to build processors with multiple cores, it will be increasingly important to have programming languages that support concurrent programming in order to better exploit the parallelism offered by these processors. In this respect, certain programming paradigms or models are considered well-suited for writing robust concurrent software: Functional programming languages, e.g. Haskell, Scala, etc. The actor model: Erlang, but also available for Scala / Java (Akka), C++ (Theron, Casablanca, ...), and other programming languages. My questions: What is the state of the art regarding the development of concurrent applications (e.g. using multi-threading) using the above languages / models? Is this area still being explored or are there well-established practices already? Will it be more complex to program applications with a higher level of concurrency, or is it just a matter of learning new paradigms and practices? How does the performance of highly concurrent software compare to the performance of more traditional software when executed on multiple core processors? For example, has anyone implemented a desktop application using C++ / Theron, or Java / Akka? Was there a boost in performance on a multiple core processor due to higher parallelism?

• unable to access shared drives n win7

  - by colin

  OK, this is doing my head in. Not your usual Win7 sharing problem. Just built a win 7 comp to go onto my home lan and be accessed by all on the network, mostly running XP SP3. Installed it as a single HD+DVD system, got it happy, then added my storage drives, set them up in the right order and letters, rebooted, and shared them. Couldn't access the computer at all from any XP machine. Set the pasword thingy in win7 to NO, and now I can "see" all four shared drives from any machine, but can access only two of them. Please tell me whats going on as I've done nothing different from one drive to the other, just installed and set up drive letters as normal, then shared the damn things. The odd thing about it? the two 1.5T drives that have a lot of data on board are accessable, the two nearly empty 500G ones are not. ANY ideas? Cheers, Colin

• Crawling a Content Folio

  - by Kyle Hatlestad

  Content Folios in WebCenter Content allow you to assemble, track, and access a logical group of documents and/or links.  It allows you to manage them as just a list of items (simple folio) or organized as a hierarchy (advanced folio).  The built-in UI in content server allows you to work with these folios, but publishing them or consuming them externally can be a bit of a challenge.   The folios themselves are actually XML files that contain the structure, attributes, and pointers to the content items.  So to publish this somewhere, such as a Site Studio page, you could perhaps use an XML parser to traverse the structure and create your output.  But XML parsers are not always the easiest or most efficient to use.  In order to more easily crawl and consume a Content Folio, Ed Bryant - Principal Sales Consultant, wrote a component to do just that.  His component adds a service which does all the work for you and returns the folio structure as a simple resultset.  So consuming and publishing that folio on a Site Studio page or in your portal using RIDC is a breeze!  For example, let's take an advanced Content Folio example like this: If we look at the native file, the XML looks like this: But if we access the folio using the new service - http://server/cs/idcplg?IdcService=FOLIO_CRAWL&dDocName=ecm008003&IsPageDebug=1 - this is what the result set looks like (using the IsPageDebug parameter). Given this as the result set, it makes it very easy to consume and repurpose that folio. You can download a copy of the sample component here. Special thanks to Ed for letting me share this component!

• Are IE 9 will have a place in heart of user ?

  - by anirudha

  in a advertisement of IE 9 MSFT compare two product first is their IE9 and second is chrome 6. I know 6 is not currently [9] but no objection because may be they make ads when 6 is currently version and have RC or beta in their hands. on IE 9 test-drive website they show many of people ads to show the user that IE9 is performance better or other chrome or Firefox not. well they not compare with Firefox because last days firefox not still in news and search trends like before RC release many of user googling for them. Well I myself found IE9 perform smoother then chrome. but what MSFT do after IE9 nothing they waiting for IE 10 not for give updates not as well as Google chrome and Firefox. Are IE9 have anything new for Developer even a small or big. well they tell you blah or useless things everytime when they make for next version no matter for you but a matter for them because they add a new thing even useless for developer. I am not have any feeling with IE bad but I like to make reviews as well as I can make. I show you something who I experience with IE and someother browser like Chrome and Firefox. IE 9 still have no plugin as well as other provided like Firefox have Firebug a great utilities who is best option for developer to debug their code. IE9 developer tool is good but still you never customize them or readymade customization available to work as in firefox many of person make customization for firebug like example :- firepicker for picking color in firebug , firebug autocomplete for intellisense like feature when you write JavaScript inside console panel , pixelperfect , firequery , sitepoint reference and many other great example we all love to use. as other things that Firefox give many things customizable like themes , ui and many thing customization means more thing user or developer want to make themselves and more contribution make them better software so Firefox is great because customization is a great thing inside firefox and chrome. if you read some post of developer on MSDN to what’s new in IE 9 developer tool that you feel they are joking whenever you see some other things of Firefox and chrome. in a Firefox a plugin perform many much things but in IE still use IE 9 developer tool no other option like in Firefox use Firebug and many other utilities to make development easier and time saving and best as we can do.if you see Firefox page on mozilla that sublines of firefox is high performance easy customization advanced security well you can say what’s performance but there is no comparison with IE because IE have only performance and nothing else. but Firefox have these three thing to make product love. and third thing I really love that security yeah security. from long time before whenever IE6 is no hackproff and many other easily hack IE6 whenever Firefox is secure. I found myself that many of website install a software on client’s computer and they still not know about them so they track everything. sometime they hijack the homepage and make their website as their homepage. sometime they do something and you trying  to go to  any website then they go to their site first. the problem I telling about not long before it’s time of late in 2008 whenever Firefox is much better then IE6. if someone have bad experience with anyone of these software share with us I like to hear your voice. whenever IE still not for use Firefox is a good option for us even user or developer. I not know why someone make next version of IE. IE still have time to go away from Web. Firefox not rude as IE they still believe in user feedback and chrome is also open the door for feedback on their product gooogle Chrome. but what thing they made in IE on user feedback nothing. they still thing to teach what they maked not thing about what user need. if you spent some hour on firefox and chrome then you found what’s matter. what thing you have whenever you use IE or other browser like google chrome and Firefox :- as a user IE give you nothing even tell you blah blah and more blah but still next version of IE means next IE6 for the web. as in Google chrome you find plugins addons or customization to make experience better but in IE9 you can’t customize anything even the themes they have by default. Firefox already have a great list of plugins or addons to make experience better with Web but IE9 have nothing. this means IE9 not for user and other like chrome and firefox give you much better experience then IE. next thing after user is developer. first thing is that all developer want smooth development who save their time not take too perhaps saving.posts on IE9 show that a list of thing improved in IE 9 developer tool but are one developer tool enough for web development so developer need more utilities to solve different different type of puzzle who IE 9 never give like in Firefox you have utilities to do a task even small or big one. in chrome same experience you have but IE9 never give any plugin or utilities to make our work faster even they are new headache for developer because IE not give update as soon as other because in Firefox and in chrome if a bug is reported then they solve them fast and distribute them in next version of software very soon but in IE wait for a long time like IE 9 and IE 8 have no official release between them as update. As my conclusion there is no reason to use IE and adopt 9 again. it’s really not for Developer or user even newbie or smart people. as a rule I want to beware you with IE because it’s my responsibilities to move the thing in good way as I can make. well are you sure that there is no reason or profit they thing to have with IE9  if not why they forget luna [windows xp] user. because they are old nothing they want to force user to give them some money by purchasing a new version of OS. so this a thing why they marketed their software. if you thing about what firefox and chrome want to make : Mozilla's mission is to promote openness, innovation and opportunity on the web. chrome mission we all see whenever we use them. but IE9 is a trick they promote because they want to add something to next version of windows. if somebody like IE9 [even surprised by ads they see or post they read] then they purchase windows soon as they possible. Well you feel that I am opposition of IE9 and favor of chrome and Firefox yeah you feel right I hate IE from a heart not from a pencil. well you get same thing when you have trying three product major I described here Chrome firefox and IE. well don’t believe on the blogs , posts or article who are provided by the merchant or vender’s website. open the eyes read and thing what they talk and feel are they really true. if you confused that compare with some other. now you know the true because no one telling so badly as a user can described who use them not only one who make their feature. always open the eyes don’t believe use your mind and find the truth. thanks for reading my post good bye and take care

• How To Backup Of MySQL Database Using PhpMyAdmin

  - by Jyoti

  It is very important to do backup of your MySql database, you will probably realize it when it is too late. A lot of web applications use MySql for storing the content. This can be blogs, and a lot of other things. When you have all your content as html files on your web server it is very easy to keep them safe from crashes, you just have a copy of them on your own PC and then upload them again after the web server is restored after the crash. All the content in the MySql database must also be backed up. If you have spent a lot of time making the content and it is only stored in the Mysql server, you will feel very bad if it gets lost for ever. Backing it up once every month or so makes sure you never loose too much of your work in case of a server crash, and it will make you sleep better at night. It is easy and fast, so there is no reason for not doing it. Step 1: Log into phpMyAdmin on your server. Step2: You can select the database that you would like to backup from the drop-down menu called Database. Step 3: A new page will be loaded in phpMyAdmin showing the selected database. In order to proceed with the backup click on the Export tab. Step 4: The options that you should select apart from the default ones are Save as file which will save the file locally to your computer in an .sql format and Add DROP TABLE which will add the drop table functionality if the table already exists in the database backup as shown below. Step 5: Click on the Go button to start the export/backup procedure for your database. A download window will pop up prompting for the exact place where you would like to save the file on your local computer. It is possible that the download starts automatically. This depends on your browser’s settings.

• Diablo 3 "freezes" periodically

  - by Shauna

  I'm running Diablo 3 (start edition, digital download) on the following: Ubuntu 12.04 64-bit (stock Unity, Gnome, etc; kernel version 3.2.0-29-generic) Wine version 1.5.11 (base, from Wine's PPA, game started with setarch i386 -3) Intel i7 920 CPU nVidia GTX260 with driver version 295.49 ("post-release updates" entry within the proprietary drivers tool), dual monitors 6GB RAM Every so often (and what appears to be at random), the game video will freeze up. I can still move the mouse, and it reacts to ctrl+alt+f2 to drop into text mode, but I can't get back to the desktop (which means I can check terminal to see what's going on after launching from terminal, especially since even in windowed mode, the secondary screen gets shut off by the game), and I can't continue to play the game. In order to get it running again, I have to restart lightdm, then relaunch the game (or, in a couple of rare cases, I had to restart the computer entirely, because running sudo service lightdmn [stop/start] doesn't appear to react). Turning down the video settings seems to have helped in some cases, but not all of them. Times it's frozen on me: The beginning of The Fallen Start quest part 6 - kill the Wretched Mother, right as you walk out of New Tristram and engage in the monsters on the northern path (repeatedly froze here until I adjusted the graphics down) Within the cinematic/event upon finding Deckard Cain While fighting the skeletons to protect Deckard Cain When about to enter Leoric's passage after Cain sends you back to where you found him That's as far as I've gotten through the game so far. Additionally, this doesn't happen on other games I play and seems to only occur with Diablo 3. Has anyone else run into this issue and know a possible cause or fix, or at least know where I can look (and what to look for) to figure out why this is happening?

• Monitor network connectivity in WP7 apps

  - by Daniel Moth

  Most interesting Windows Phone apps rely on some network service for their functionality. So at some point in your app you may need to know programmatically if there is network connection available or not. For example, the Translator by Moth app relies on the Bing Translation service for translations. When a request for translation (text or voice) is made, the network call may fail. The failure reason is not evident from any of the return results, so I check the connection to see if it is present. Dependent on that, a different message is shown to the user. Before the translation phase is even reached, at the app start up time the Bing service is queried for its list of  languages; in that case I don't want to show the user a message and instead want to be notified when the network is available in order to send the query out again. So for those two requirements (which I imagine are common in other apps) I wrote a simple wrapper MyNetwork static class to the framework APIs: Call once MyNetwork.MonitorNetworkAvailability() method so it monitors the network change At any time check the MyNetwork.IsConnected property to check for network presence Subscribe to its MyNetwork.ConnectionEstablished event Optionally, during debugging use its MyNetwork.ChangeStatus method to simulate a change in network status As usual, there may be better ways to achieve this, but this class works perfectly for my scenarios. You can download the code here: MyNetworks.cs. Comments about this post welcome at the original blog.

• NVRAM for journals on Linux?

  - by symcbean

  I've been thinking about ways of speeding up disk I/O, and one of the bottlenecks I keep coming back to is the journal. There's an obvious benefit to using an SSD for the journal - over and above just write caching unless of course I just disable the journal with the write cache (after all devicemapper doesn't seem to support barriers). In order to get the benefits from using a BB write cache on the controller, then I'd need to disable journalling - but then the OS should try to fsck the system after an outage. Of course if the OS knows what's in the batter-backed memory then it could use it as the journal - but that means it must be exposed as a block device and only be under the control of the operating system. However I've not been able to find a suitable low-cost device (no, write-levelling for Flash is not adequate for a journal, at least one which uses Smartmedia). While there's no end of flash devices, disk/array controllers with BB write caches, so far I've not found anything which just gives me non-volatile memory addressable as a block storage device.

• Move drive from iomega home media nas to win 7 pc

  - by user41993

  My Iomega Home Media NAS would not boot, so I unscrewed the enclosure and removed the drive out. It's a 500 GB SATA drive that I plugged into my Win 7 PC so that I could backup the data. Windows does recognize it (it's there in disk management) but I can't assign a letter to it in order to access it. The only option available is Delete Volume... which I obviously don't want to do :) How can I accomplish getting the data off that drive? Thanks.

• Redirect input from one terminal to another

  - by Niki Yoshiuchi

  I have sshed into a linux box and I'm using dvtm and bash (although I have also tried this with Gnu screen and bash). I have two terminals, current /dev/pts/29 and /dev/pts/130. I want to redirect the input from one to the other. From what I understand, in /dev/pts/130 I can type: cat </dev/pts/29 And then when I type in /dev/pts/29 the characters I type should show up in /dev/pts/130. However what ends up happening is that every other character I type gets redirected. For example, if I type "hello" I get this: /dev/pts/29 | /dev/pts/130 $ | $ cat </dev/pts/29 $ el | hlo This is really frustrating as I need to do this in order to redirect the io of a process running in gdb (I've tried both run /dev/pts/# and set inferior-tty /dev/pts/# and both resulted in the aforementioned behavior). Am I doing something wrong, or is this a bug in bash/screen/dvtm?

• GitHub: Are there external tools for managing issues list vs. project backlog

  - by DXM

  Recently I posted one of my the projects1 on GitHub and as I was exploring capabilities of the site, I noticed they have a rather decent issue tracking section. I want to use that section as a) other people can report bugs if they'd like and b) other people can see which bugs I'm aware of. However, as others have noted, issues list cannot be prioritized in order to create a project backlog. For now my backlog has been a text file, but I'd like to be able to have it integrated so the same information isn't maintained in different places. Having a fully ordered list, which is something we also practice at work, has been very useful as I can open one file, start with line 1 and fire off 2 or 3 items in one sitting without having to go back to a full issues/stories bucket. GitHub doesn't offer this. What GitHub does offer is a very nice and clean API so issues can easily be exported into anything else. I've searched to see if there are other websites (like Trello) that integrate with GitHub issues, but did not find anything. Does anyone know of such a product, service or offline tool? Those that use GitHub, what is your experience in managing backlog? I kinda hate the idea of manually managing two disconnected lists like some people seem to be doing with Wiki project pages. 1 - are shameless plugs allowed no this site? Searched but didn't find a definite answer. If it's bad practice, STOP and don't read further As a developer I got sick and tired of navigating to same set of folders 30 times a day, so I wrote a little, auto-collapsible utility that gets stuck to the desktop and allows easy access to the folders you constantly use.
